No! It's not a joke.

Take a look here: http://msdn.microsoft.com/en-us/library/ms186939.aspx

Character data types that are either fixed-length, nchar, or variable-length, nvarchar, Unicode data and use the UNICODE UCS-2 character set.

And also here: http://en.wikipedia.org/wiki/UTF-16

The older UCS-2 (2-byte Universal Character Set) is a similar character encoding that was superseded by UTF-16 in version 2.0 of the Unicode standard in July 1996.

You could use the Laravel query builder, but this is not the best way to do it.

Check Wader's answer below for the Eloquent way - which is better as it allows you to check that there is actually a user that matches the email address, and handle the error if there isn't.

DB::table('users')
        ->where('email', $userEmail)  // find your user by their email
        ->limit(1)  // optional - to ensure only one record is updated.
        ->update(array('member_type' => $plan));  // update the record in the DB. 

If you have multiple fields to update you can simply add more values to that array at the end.

HashMap is unordered per the second line of the documentation:

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Perhaps you can do as aix suggests and use a LinkedHashMap, or another ordered collection. This link can help you find the most appropriate collection to use.

For Notepad++ 5.9

1. Press Ctrl+H
2. Select Search mode Extended(\n, \r, \t, \o, \x...)
3. Enter Find what: \r\n
4. Enter Replace with: ,
5. Replace_All should get the required result.

In case of multibyte (unicode) strings using str[0] can cause a trouble. mb_substr() is a better solution. For example:

$first_char = mb_substr($title, 0, 1);

Some details here: Get first character of UTF-8 string

this procedure works pretty well

give it a try.

I used to use PageSpiner from optima Software (http://www.optima-system.com/pagespinner/) but converted to Coda when Panic first released it and haven't looked back.

Now that the latest version has multi-file find and replace it has just about everything I need and I use it on a daily basis. Another vote for Coda from me.

The functional way of achieving this is to unzip the list using:

sample = [(2, 9), (2, 9), (8, 9), (10, 9), (23, 26), (1, 9), (43, 44)]
first,snd = zip(*sample)
print(first,snd)

(2, 2, 8, 10, 23, 1, 43) (9, 9, 9, 9, 26, 9, 44)

The right way to iterate on a list inside list is:

//iterate on the general list
for(int i = 0 ; i < collection.size() ; i++) {
    ArrayList<String> currentList = collection.get(i);
    //now iterate on the current list
    for (int j = 0; j < currentList.size(); j++) {
        String s = currentList.get(1);
    }
}

Try @title = "stuff". It worked for me.

Exponential (You have an exponential function if MINIMAL ONE EXPONENT is dependent on a parameter):

• E.g. f(x) = constant ^ x

Polynomial (You have a polynomial function if NO EXPONENT is dependent on some function parameters):

• E.g. f(x) = x ^ constant

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

if you build the source files with lower version of Java (example Java1.5) and trying to run that program/application with higher version of Java (example java 1.6) you will get this problem. for better explanation see this link. click here

There is more than one type of UUID, so "how safe" depends on which type (which the UUID specifications call "version") you are using.

• Version 1 is the time based plus MAC address UUID. The 128-bits contains 48-bits for the network card's MAC address (which is uniquely assigned by the manufacturer) and a 60-bit clock with a resolution of 100 nanoseconds. That clock wraps in 3603 A.D. so these UUIDs are safe at least until then (unless you need more than 10 million new UUIDs per second or someone clones your network card). I say "at least" because the clock starts at 15 October 1582, so you have about 400 years after the clock wraps before there is even a small possibility of duplications.

• Version 4 is the random number UUID. There's six fixed bits and the rest of the UUID is 122-bits of randomness. See Wikipedia or other analysis that describe how very unlikely a duplicate is.

• Version 3 is uses MD5 and Version 5 uses SHA-1 to create those 122-bits, instead of a random or pseudo-random number generator. So in terms of safety it is like Version 4 being a statistical issue (as long as you make sure what the digest algorithm is processing is always unique).

• Version 2 is similar to Version 1, but with a smaller clock so it is going to wrap around much sooner. But since Version 2 UUIDs are for DCE, you shouldn't be using these.

So for all practical problems they are safe. If you are uncomfortable with leaving it up to probabilities (e.g. your are the type of person worried about the earth getting destroyed by a large asteroid in your lifetime), just make sure you use a Version 1 UUID and it is guaranteed to be unique (in your lifetime, unless you plan to live past 3603 A.D.).

So why doesn't everyone simply use Version 1 UUIDs? That is because Version 1 UUIDs reveal the MAC address of the machine it was generated on and they can be predictable -- two things which might have security implications for the application using those UUIDs.

Try using: from cv2 import cv

It works for me.

   implementation 'com.google.android.gms:play-services-location:17.0.0'

   

Many answers suggest to use mysql --version. But the mysql programm is the client. The server is mysqld. So the command should be

mysqld --version

or

mysqld --help

That works for me on Debian and Windows.

When connected to a MySQL server with a client you can use

select version()

or

select @@version

Both nginx -t and nginx -V would print out the default nginx config file path.

$ nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

$ nginx -V
nginx version: nginx/1.11.1
built by gcc 4.9.2 (Debian 4.9.2-10)
built with OpenSSL 1.0.1k 8 Jan 2015
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf ...

If you want, you can get the config file by:

$ nginx -V 2>&1 | grep -o '\-\-conf-path=\(.*conf\)' | cut -d '=' -f2
/etc/nginx/nginx.conf

Even if you have loaded some other config file, they would still print out the default value.

ps aux would show you the current loaded nginx config file.

$ ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root        11  0.0  0.2  31720  2212 ?        Ss   Jul23   0:00 nginx: master process nginx -c /app/nginx.conf

So that you could actually get the config file by for example:

$ ps aux | grep "[c]onf" | awk '{print $(NF)}'
/app/nginx.conf

JChronic is your best choice. Here's an example that adds a .fromString() method to the Date class that parses just about anything you can throw at it:

Date.metaClass.'static'.fromString = { str ->
    com.mdimension.jchronic.Chronic.parse(str).beginCalendar.time
}

You can call it like this:

println Date.fromString("Tue Aug 10 16:02:43 PST 2010")
println Date.fromString("july 1, 2012")
println Date.fromString("next tuesday")

In my opinion the best tool for such testing is curl. Its --upload-file option uploads a file by PUT, which is exactly what you want (and it can do much more, like modifying HTTP headers, in case you need it):

curl http://myservice --upload-file file.txt

Try:

output=$(ps -ef | awk '/siebsvc –s siebsrvr/ && !/awk/ { a++ } END { print a }'); echo $output

Wrapping your command in $( ) tells the shell to run that command, instead of attempting to set the command itself to the variable named "output". (Note that you could also use backticks `command`.)

I can highly recommend http://tldp.org/LDP/abs/html/commandsub.html to learn more about command substitution.

Also, as 1_CR correctly points out in a comment, the extra space between the equals sign and the assignment is causing it to fail. Here is a simple example on my machine of the behavior you are experiencing:

jed@MBP:~$ foo=$(ps -ef |head -1);echo $foo
UID PID PPID C STIME TTY TIME CMD

jed@MBP:~$ foo= $(ps -ef |head -1);echo $foo
-bash: UID: command not found
UID PID PPID C STIME TTY TIME CMD

From stack trace:

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

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

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

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

There's a free Java API called JFreeWebSearch which uses the already mentioned Faroo: http://www.ke.tu-darmstadt.de/resources/jfreewebsearch

Imagine that you have registered for a tech conference. You arrive and walk up to the registration table outside to get your conference badge. You have to first show some form of identification, such as a driver's license. Your driver's license identifies you (with your picture, for example) and is distributed by a trusted entity (the DMV). This is authentication.

The person hands you your badge, which is red, blue, or green. Walking around inside the conference, some of the exhibits are color-coded. With a green badge, you can enter the green exhibits, but not the blue or red exhibits. The badge is not distributed by the DMV -- rather, it is distributed by the conference itself, to access conference resources inside the conference hall.

There is not necessarily anything about the badge that identifies you (it may have your name printed on it, but you can easily borrow your friend's blue badge to visit a blue exhibit -- nobody is going to check your name, just the color blue). The color of your badge grants you access to exhibits. This is authorization.

For Chrome users, I recommend Stylebot, which will let you override any CSS on any page, also let you search and install other share custom CSS. However, for our purpose we don't need any advance theme. Open Stylebot, change to Edit CSS. Jupyter captures some keystrokes, so you will not be able to type the code below in. Just copy and paste, or just your editor:

#notebook-container.container {
    width: 90%;
}

Change the width as you like, I find 90% looks nicer than 100%. But it is totally up to your eye.

Unfortunately, it is not possible to "get" the height of an element via CSS because CSS is not a language that returns any sort of data other than rules for the browser to adjust its styling.

Your resolution can be achieved with jQuery, or alternatively, you can fake it with CSS3's transform:translateY(); rule.

The CSS Route

If we assume that your target div in this instance is 200px high - this would mean that you want the div to have a margin of 190px?

This can be achieved by using the following CSS:

.dynamic-height {
    -webkit-transform: translateY(100%); //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
    transform: translateY(100%);         //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
    margin-top: -10px;
}

In this instance, it is important to remember that translateY(100%) will move the element in question downwards by a total of it's own length.

The problem with this route is that it will not push element below it out of the way, where a margin would.

The jQuery Route

If faking it isn't going to work for you, then your next best bet would be to implement a jQuery script to add the correct CSS for you.

jQuery(document).ready(function($){ //wait for the document to load
    $('.dynamic-height').each(function(){ //loop through each element with the .dynamic-height class
        $(this).css({
            'margin-top' : $(this).outerHeight() - 10 + 'px' //adjust the css rule for margin-top to equal the element height - 10px and add the measurement unit "px" for valid CSS
        });
    });
});

If you want to configure your project logging using log4Net, while using a class library, There is no actual need of any config file. You can configure your log4net logger in a class and can use that class as library.

As log4net provides all the options to configure it.

Please find the code below.

public static void SetLogger(string pathName, string pattern)
        {
            Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();

            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = pattern;
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = false;
            roller.File = pathName;
            roller.Layout = patternLayout;
            roller.MaxSizeRollBackups = 5;
            roller.MaximumFileSize = "1GB";
            roller.RollingStyle = RollingFileAppender.RollingMode.Size;
            roller.StaticLogFileName = true;
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

            MemoryAppender memory = new MemoryAppender();
            memory.ActivateOptions();
            hierarchy.Root.AddAppender(memory);

            hierarchy.Root.Level = log4net.Core.Level.Info;
            hierarchy.Configured = true;
      }

Now instead of calling XmlConfigurator.Configure(new FileInfo("app.config")) you can directly call SetLogger with desired path and pattern to set the logger in Global.asax application start function.

And use the below code to log the error.

        public static void getLog(string className, string message)
        {
            log4net.ILog iLOG = LogManager.GetLogger(className);
            iLOG.Error(message);    // Info, Fatal, Warn, Debug
        }

By using following code you need not to write a single line neither in application web.config nor inside the app.config of library.

Highlight the cells, format cells, select Custom then select zero.

You could use

os.path.abspath(path_with_backlash)

it returns the path with \

Why could you not just do something like this?

class Foo {
  constructor(myObj){
     Object.assign(this, myObj);
  }
  get name() { return this._name; }
  set name(v) { this._name = v; }
}

let foo = new Foo({ name: "bat" });
foo.toJSON() //=> your json ...

Just an idea, but is it possible to put an onclick on each of the <option> elements?

<select>
  <option onclick="doSomething(this);">A</option>
  <option onclick="doSomething(this);">B</option>
  <option onclick="doSomething(this);">C</option>
</select>

Another option could be to use onblur on the select. This will fire anytime the user clicks away from the select. At this point you could determine what option was selected. To have this even trigger at the correct time, the onclick of the option's could blur the field (make something else active or just .blur() in jQuery).

you can try to add these code:

VelocityEngine ve = new VelocityEngine();
String vmPath = request.getSession().getServletContext().getRealPath("${your dir}");
Properties p = new Properties();
p.setProperty("file.resource.loader.path", vmPath+"//");
ve.init(p);

I do this, and pass!

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

there is an important difference between delete and splice:

ORIGINAL ARRAY:

[<1 empty item>, 'one',<3 empty items>, 'five', <3 empty items>,'nine']

AFTER SPLICE (array.splice(1,1)):

[ <4 empty items>, 'five', <3 empty items>, 'nine' ]

AFTER DELETE (delete array[1]):

[ <5 empty items>, 'five', <3 empty items>, 'nine' ]

The accepted answer has to load the whole file into memory, which doesn't work nicely for large files. The following solution writes the file contents with the new data inserted into the right line to a temporary file in the same directory (so on the same file system), only reading small chunks from the source file at a time. It then overwrites the source file with the contents of the temporary file in an efficient way (Python 3.8+).

from pathlib import Path
from shutil import copyfile
from tempfile import NamedTemporaryFile

sourcefile = Path("/path/to/source").resolve()
insert_lineno = 152  # The line to insert the new data into.
insert_data = "..."  # Some string to insert.

with sourcefile.open(mode="r") as source:
    destination = NamedTemporaryFile(mode="w", dir=str(sourcefile.parent))
    lineno = 1

    while lineno < insert_lineno:
        destination.file.write(source.readline())
        lineno += 1

    # Insert the new data.
    destination.file.write(insert_data)

    # Write the rest in chunks.
    while True:
        data = source.read(1024)
        if not data:
            break
        destination.file.write(data)

# Finish writing data.
destination.flush()
# Overwrite the original file's contents with that of the temporary file.
# This uses a memory-optimised copy operation starting from Python 3.8.
copyfile(destination.name, str(sourcefile))
# Delete the temporary file.
destination.close()

EDIT 2020-09-08: I just found an answer on Code Review that does something similar to above with more explanation - it might be useful to some.

I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.

I'm omitting the com port settings here:

>>>import serial

>>>ser = serial.Serial(5)

>>>ser.close()

>>>ser.open()

>>>ser.write("1".encode())

Sometimes you can refactor your @Component to use constructor or setter based injection to setup your testcase (you can and still rely on @Autowired). Now, you can create your test entirely without a mocking framework by implementing test stubs instead (e.g. Martin Fowler's MailServiceStub):

@Component
public class MyLauncher {

    private MyService myService;

    @Autowired
    MyLauncher(MyService myService) {
        this.myService = myService;
    }

    // other methods
}

public class MyServiceStub implements MyService {
    // ...
}

public class MyLauncherTest
    private MyLauncher myLauncher;
    private MyServiceStub myServiceStub;

    @Before
    public void setUp() {
        myServiceStub = new MyServiceStub();
        myLauncher = new MyLauncher(myServiceStub);
    }

    @Test
    public void someTest() {

    }
}

This technique especially useful if the test and the class under test is located in the same package because then you can use the default, package-private access modifier to prevent other classes from accessing it. Note that you can still have your production code in src/main/java but your tests in src/main/test directories.

If you like Mockito then you will appreciate the MockitoJUnitRunner. It allows you to do "magic" things like @Manuel showed you:

@RunWith(MockitoJUnitRunner.class)
public class MyLauncherTest
    @InjectMocks
    private MyLauncher myLauncher; // no need to call the constructor

    @Mock
    private MyService myService;

    @Test
    public void someTest() {

    }
}

Alternatively, you can use the default JUnit runner and call the MockitoAnnotations.initMocks() in a setUp() method to let Mockito initialize the annotated values. You can find more information in the javadoc of @InjectMocks and in a blog post that I have written.

Combining several conditions:

• write mongo query in JS file and send it from terminal
• switch/define a database programmatically
• output all found records
• cut initial output lines
• save the output into JSON file

myScriptFile.js

// Switch current database to "mydatabase"
db = db.getSiblingDB('mydatabase');

// The mark for cutting initial output off
print("CUT_TO_HERE");

// Main output
// "toArray()" method allows to get all records
printjson( db.getCollection('jobs').find().toArray() );

Sending the query from terminal

-z key of sed allows treat output as a single multi-line string

$> mongo localhost --quiet myScriptFile.js | sed -z 's/^.*CUT_TO_HERE\n//' > output.json

Get the latest pre-built OpenCV for Android release from https://github.com/opencv/opencv/releases and unpack it (for example, opencv-4.4.0-android-sdk.zip).

Create an empty Android Studio project

Open Android Studio. Start a new project. 

Keep default target settings.

Use "Empty Activity" template. Name activity as MainActivity with a corresponding layout activity_main. Plug in your device and run the project. It should be installed and launched successfully before we'll go next.

 Add OpenCV dependency

Go to File->New->Import module

and provide a path to unpacked_OpenCV_package/sdk/java. The name of module detects automatically. Disable all features that Android Studio will suggest you on the next window.

Configure your library build.gradle (openCVLibrary build.gradle)

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    buildTypes {
        release {

This is basically the same answer provided by Evert, but extended to show-off some cool options of fill_between

from matplotlib import pyplot as pl
import numpy as np

pl.clf()
pl.hold(1)

x = np.linspace(0, 30, 100)
y = np.sin(x) * 0.5
pl.plot(x, y, '-k')


x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape) +.1
y += np.random.normal(0, 0.1, size=y.shape)

pl.plot(x, y, 'k', color='#CC4F1B')
pl.fill_between(x, y-error, y+error,
    alpha=0.5, edgecolor='#CC4F1B', facecolor='#FF9848')

y = np.cos(x/6*np.pi)    
error = np.random.rand(len(y)) * 0.5
y += np.random.normal(0, 0.1, size=y.shape)
pl.plot(x, y, 'k', color='#1B2ACC')
pl.fill_between(x, y-error, y+error,
    alpha=0.2, edgecolor='#1B2ACC', facecolor='#089FFF',
    linewidth=4, linestyle='dashdot', antialiased=True)



y = np.cos(x/6*np.pi)  + np.sin(x/3*np.pi)  
error = np.random.rand(len(y)) * 0.5
y += np.random.normal(0, 0.1, size=y.shape)
pl.plot(x, y, 'k', color='#3F7F4C')
pl.fill_between(x, y-error, y+error,
    alpha=1, edgecolor='#3F7F4C', facecolor='#7EFF99',

pl.show()

This should work:

public static dynamic Cast(dynamic obj, Type castTo)
{
    return Convert.ChangeType(obj, castTo);
}

Edit

I've written the following test code:

var x = "123";
var y = Cast(x, typeof(int));
var z = y + 7;
var w = Cast(z, typeof(string)); // w == "130"

It does resemble the kind of "typecasting" one finds in languages like PHP, JavaScript or Python (because it also converts the value to the desired type). I don't know if that's a good thing, but it certainly works... :-)

For a lack of a better solution, I got this working for me: Assume I have 1 activity (MyActivity) and few fragments that replaces each other (only one is visible at a time).

In MyActivity, add this listener:

getSupportFragmentManager().addOnBackStackChangedListener(getListener());

(As you can see I'm using the compatibility package).

getListener implementation:

private OnBackStackChangedListener getListener()
    {
        OnBackStackChangedListener result = new OnBackStackChangedListener()
        {
            public void onBackStackChanged() 
            {                   
                FragmentManager manager = getSupportFragmentManager();

                if (manager != null)
                {
                    MyFragment currFrag = (MyFragment) manager.findFragmentById(R.id.fragmentItem);

                    currFrag.onFragmentResume();
                }                   
            }
        };

        return result;
    }

MyFragment.onFragmentResume() will be called after a "Back" is pressed. few caveats though:

1. It assumes you added all transactions to the backstack (using FragmentTransaction.addToBackStack())
2. It will be activated upon each stack change (you can store other stuff in the back stack such as animation) so you might get multiple calls for the same instance of fragment.

You can check

if(Looper.myLooper() == Looper.getMainLooper()) {
   // You are on mainThread 
}else{
// you are on non-ui thread
}

Some modifications were made on posted answer UnderWaterKremlin to make it python3 proof. A surprising result below as answer.

System specs:

• python =3.7.4,
• conda = 4.8.0
• 3.6Ghz, 8 core, 16gb.

import timeit

d = {x: x**2 for x in range(1000)}
#print (d)
print (len(d))
# 1000

print (len(d.keys()))
# 1000

print (timeit.timeit('len({x: x**2 for x in range(1000)})', number=100000))        # 1

print (timeit.timeit('len({x: x**2 for x in range(1000)}.keys())', number=100000)) # 2

Result:

1) = 37.0100378

2) = 37.002148899999995

So it seems that len(d.keys()) is currently faster than just using len().

For convenience, here's an implementation that works for 0 to 70 arguments, and works in Visual Studio, GCC, and Clang. I believe it will work in Visual Studio 2010 and later, but have only tested it in VS2013.

You can do it using javascript

• Change iframe background color
• Change background color of the loaded page (same domain)

Plain javascript

var iframe = document.getElementsByTagName('iframe')[0];
iframe.style.background = 'white';
iframe.contentWindow.document.body.style.backgroundColor = 'white';

jQuery

$('iframe').css('background', 'white');
$('iframe').contents().find('body').css('backgroundColor', 'white');

It's better to encode first to a JSON string and then encode with Base64, for example, on the server side in reverse order: use first the base64_decode and then json_decode functions. So you will restore your PHP array.

You can use Facebook Chat API to send private messages, here is an example in Ruby using xmpp4r_facebook gem:

sender_chat_id = "-#{sender_uid}@chat.facebook.com"
receiver_chat_id = "-#{receiver_uid}@chat.facebook.com"
message_body = "message body"
message_subject = "message subject"

jabber_message = Jabber::Message.new(receiver_chat_id, message_body)
jabber_message.subject = message_subject

client = Jabber::Client.new(Jabber::JID.new(sender_chat_id))
client.connect
client.auth_sasl(Jabber::SASL::XFacebookPlatform.new(client,
   ENV.fetch('FACEBOOK_APP_ID'), facebook_auth.token,
   ENV.fetch('FACEBOOK_APP_SECRET')), nil)
client.send(jabber_message)
client.close

If JDK installed but still not working.

In Eclipse follow below steps:- Window --> Preference --> Installed JREs -->Change path of JRE to JDK(add).

Yes. There are methods on the String itself for this.

Note that the result depends on the Locale the JVM is using. Beware, locales is an art in itself.

Assign NOW() to a variable then update the datetime with variable:

update_date_time=now()

now update like this

UPDATE table SET datetime =update_date_time;

correct the syntax, as per your requirement

Android MediaPlayer doesn't support streaming of MP3 natively until 2.2. In older versions of the OS it appears to only stream 3GP natively. You can try the pocketjourney code, although it's old (there's a new version here) and I had trouble making it sticky — it would stutter whenever it refilled the buffer.

The NPR News app for Android is open source and uses a local proxy server to handle MP3 streaming in versions of the OS before 2.2. You can see the relevant code in lines 199-216 (r94) here: http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/PlaybackService.java?r=7cf2352b5c3c0fbcdc18a5a8c67d836577e7e8e3

And this is the StreamProxy class: http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/StreamProxy.java?r=e4984187f45c39a54ea6c88f71197762dbe10e72

The NPR app is also still getting the "error (-38, 0)" sometimes while streaming. This may be a threading issue or a network change issue. Check the issue tracker for updates.

I found that the best way to embed a pdf for my case was by using bootstrap because not only does it show the pdf but it also fill available space and you can specify the ratio as you wish. Here's an example of what i made with it:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css">

<div class="embed-responsive embed-responsive-1by1">
  <iframe class="embed-responsive-item" src="http://example.com/the.pdf" type="application/pdf" allowfullscreen></iframe>
</div>

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

This problem was driving me crazy too. I was using PHP on my server side so I was not able to use @The Lazy Log(ruby) & @deweydb(python) solutions. However it pointed me to the right direction. I fixed it on the backed using Imagick's getImageOrientation().

<?php 
// Note: $image is an Imagick object, not a filename! See example use below. 
function autoRotateImage($image) { 
    $orientation = $image->getImageOrientation(); 

    switch($orientation) { 
        case imagick::ORIENTATION_BOTTOMRIGHT: 
            $image->rotateimage("#000", 180); // rotate 180 degrees 
        break; 

        case imagick::ORIENTATION_RIGHTTOP: 
            $image->rotateimage("#000", 90); // rotate 90 degrees CW 
        break; 

        case imagick::ORIENTATION_LEFTBOTTOM: 
            $image->rotateimage("#000", -90); // rotate 90 degrees CCW 
        break; 
    } 

    // Now that it's auto-rotated, make sure the EXIF data is correct in case the EXIF gets saved with the image! 
    $image->setImageOrientation(imagick::ORIENTATION_TOPLEFT); 
} 
?>

I had exactly this problem running ff4 on a mac. I had a local development server running and my @font-face declaration worked fine. I migrated to live and FF would 'flash' the correct type on first page load, but when navigating deeper the typeface defaulted to the browser stylesheet.

I found the solution lay in adding the following declaration to .htaccess

<FilesMatch "\.(ttf|otf|eot)$">
    <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
    </IfModule>
</FilesMatch>

As Kaboing mentioned, MAXDOP(n) actually controls the number of CPU cores that are being used in the query processor.

On a completely idle system, SQL Server will attempt to pull the tables into memory as quickly as possible and join between them in memory. It could be that, in your case, it's best to do this with a single CPU. This might have the same effect as using OPTION (FORCE ORDER) which forces the query optimizer to use the order of joins that you have specified. IN some cases, I have seen OPTION (FORCE PLAN) reduce a query from 26 seconds to 1 second of execution time.

Books Online goes on to say that possible values for MAXDOP are:

0 - Uses the actual number of available CPUs depending on the current system workload. This is the default value and recommended setting.

1 - Suppresses parallel plan generation. The operation will be executed serially.

2-64 - Limits the number of processors to the specified value. Fewer processors may be used depending on the current workload. If a value larger than the number of available CPUs is specified, the actual number of available CPUs is used.

I'm not sure what the best usage of MAXDOP is, however I would take a guess and say that if you have a table with 8 partitions on it, you would want to specify MAXDOP(8) due to I/O limitations, but I could be wrong.

Here are a few quick links I found about MAXDOP:

General guidelines to use to configure the MAXDOP option

In jQuery, the fn property is just an alias to the prototype property.

The jQuery identifier (or $) is just a constructor function, and all instances created with it, inherit from the constructor's prototype.

A simple constructor function:

function Test() {
  this.a = 'a';
}
Test.prototype.b = 'b';

var test = new Test(); 
test.a; // "a", own property
test.b; // "b", inherited property

A simple structure that resembles the architecture of jQuery:

(function() {
  var foo = function(arg) { // core constructor
    // ensure to use the `new` operator
    if (!(this instanceof foo))
      return new foo(arg);
    // store an argument for this example
    this.myArg = arg;
    //..
  };

  // create `fn` alias to `prototype` property
  foo.fn = foo.prototype = {
    init: function () {/*...*/}
    //...
  };

  // expose the library
  window.foo = foo;
})();

// Extension:

foo.fn.myPlugin = function () {
  alert(this.myArg);
  return this; // return `this` for chainability
};

foo("bar").myPlugin(); // alerts "bar"

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

DEMO: http://jsfiddle.net/Y4bHh/

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

There is no functional or performance difference between the two. Use whichever syntax appeals to you.

It's just like the use of AS and IS when declaring a function or procedure. They are completely interchangeable.

>>> mydict = {'a':1,'b':3,'c':2}
>>> sorted(mydict, key=lambda key: mydict[key])
['a', 'c', 'b']

select P.*,
A.Street,
A.City,
A.State
from Preson P
inner join Address A on P.id=A.Person_id
where A.Zip=97229
Order by A.Street,A.City,A.State

For positive integer values without separators:

return ( data !== '' && data === data.replace(/\D/, '') );

Tests 1. if not empty and 2. if value is equal to the result of a replace of a non-digit char in its value.

Sorry for comment in an old post but if you want to use an else if statement this will help you

{% if title == source %}
    Do This
{% elif title == value %}
    Do This
{% else %}
    Do This
{% endif %}

To insert a CR into XML, you need to use its character entity 
.

This is because compliant XML parsers must, before parsing, translate CRLF and any CR not followed by a LF to a single LF. This behavior is defined in the End-of-Line handling section of the XML 1.0 specification.

Adding binding redirect configuration for Newtonsoft.Json in your configuration file (web.config) will resolve the issue.

<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">   
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>

Since Newtonsoft.Json version in your case is 9 update the version appropriatly in the configuration.

If this configuration does not work make sure the namespace (xmlns) in your configuration tag is correct or remove the name space completely.

I was looking for this to use on link-buttons within an ASP.NET Gridview (GridView Control build in Commands) So the "Confirm" action in the dialog needs to activate a script generated by the Gridview control at run-time. this worked for me:

 $(".DeleteBtnClass").click(function (e) {
     e.preventDefault();
     var inlineFunction = $(this).attr("href") + ";";
     $("#dialog").dialog({
         buttons: {
             "Yes": function () {
                 eval(inlineFunction); // eval() can be harmful!
             },
                 "No": function () {
                 $(this).dialog("close");
             }
         }
     });
 });

Apart from the alternative solutions that were posted here (which are correct), no one has actually answered your question by addressing what was wrong with your code.

It seems as though you were trying to implement a selection sort algorithm. I will not go into the details of how sorting works here, but I have included a few links for your reference =)

Your code was syntactically correct, but logically wrong. You were partially sorting your strings by only comparing each string with the strings that came after it. Here is a corrected version (I retained as much of your original code to illustrate what was "wrong" with it):

static  String Array[]={" Hello " , " This " , "is ", "Sorting ", "Example"};
String  temp;

//Keeps track of the smallest string's index
int  shortestStringIndex; 

public static void main(String[] args)  
{              

 //I reduced the upper bound from Array.length to (Array.length - 1)
 for(int j=0; j < Array.length - 1;j++)
 {
     shortestStringIndex = j;

     for (int i=j+1 ; i<Array.length; i++)
     {
         //We keep track of the index to the smallest string
         if(Array[i].trim().compareTo(Array[shortestStringIndex].trim())<0)
         {
             shortestStringIndex = i;  
         }
     }
     //We only swap with the smallest string
     if(shortestStringIndex != j)
     {
         String temp = Array[j];
         Array[j] = Array[shortestStringIndex]; 
         Array[shortestStringIndex] = temp;
     }
 }
}

Further Reading

The problem with this approach is that its asymptotic complexity is O(n^2). In simplified words, it gets very slow as the size of the array grows (approaches infinity). You may want to read about better ways to sort data, such as quicksort.

var Person = function (lastname, age, job){
this.name = name;
this.age = age;
this.job = job;
this.changeName = function(name){
this.lastname = name;
}
}
var myWorker = new Person('Adeola', 23, 'Web Developer');
myWorker.changeName('Timmy');

console.log("New Worker" + myWorker.lastname);

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

If you want to remove/clean all the values from local storage than use

localStorage.clear();

And if you want to remove the specific item from local storage than use the following code

localStorage.removeItem(key);

Assert is very useful when developing. You use it when something just cannot happen if your code is working correctly. It's easy to use, and can stay in the code for ever, because it will be turned off in real life.

If there is any chance that the condition can occur in real life, then you must handle it.

I love it, but don't know how to turn it on in Eclipse/Android/ADT . It seems to be off even when debugging. (There is a thread on this, but it refers to the 'Java vm', which does not appear in the ADT Run Configuration).

In Centos

 sudo yum install php-xml

and restart apache

jQuery Ajax loader is not working well when you call two APIs simultaneously. To resolve this problem you have to call the APIs one by one using the isAsync property in Ajax setting. You also need to make sure that there should not be any error in the setting. Otherwise, the loader will not work. E.g undefined content-type, data-type for POST/PUT/DELETE/GET call.

in main:

@Override
public void onRestart()
{
    super.onRestart();
    finish();
    startActivity(getIntent());
}

I don't think there is a way to do variable length string comparisons completely in preprocessor directives. You could perhaps do the following though:

#define USER_JACK 1
#define USER_QUEEN 2

#define USER USER_JACK 

#if USER == USER_JACK
#define USER_VS USER_QUEEN
#elif USER == USER_QUEEN
#define USER_VS USER_JACK
#endif

Or you could refactor the code a little and use C code instead.

In my case error is because i have put ">>" twice

mongodump --db=$DB_NAME --collection=$col --out=$BACKUP_LOCATION/$DB_NAME-$BACKUP_DATE >> >> $LOG_PATH

i just correct it as

mongodump --db=$DB_NAME --collection=$col --out=$BACKUP_LOCATION/$DB_NAME-$BACKUP_DATE >> $LOG_PATH

With the latest version of Picasso (2.71828 at the time of writing this answer), the with method has been deprecated.

So the correct way would be-

Picasso.get().load("https://<image-url>").into(imageView);

where imageView is the ImageView you want to load your image into.

After installing weblogic and forms server on a Linux machine we met some problems initializing sqlplus and tnsping. We altered the bash_profile in a way that the forms_home acts as the oracle home. It works fine, both commands (sqlplus and tnsping) are executable for user oracle

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc

Use a slice, not an arrray. Just create it using

reg := []string {"a","b","c"}

An alternative would have been to convert your array to a slice when joining :

fmt.Println(strings.Join(reg[:],","))

Read the Go blog about the differences between slices and arrays.

In my case I didn't need entryComponents at all - just the basic setup as described in the link below, but I needed to include the import in both the main app module and the enclosing module.

imports: [
    NgbModule.forRoot(),
    ...
]

https://medium.com/@sunilk/getting-started-angular-6-and-ng-bootstrap-4-4b314e015c1c

You only need to add it to entryComponents if a component will be included in the modal. From the docs:

You can pass an existing component as content of the modal window. In this case remember to add content component as an entryComponents section of your NgModule.

The best way I've found is to delegate the exception to the HandlerExceptionResolver

@Component("restAuthenticationEntryPoint")
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Autowired
    private HandlerExceptionResolver resolver;

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        resolver.resolveException(request, response, null, exception);
    }
}

then you can use @ExceptionHandler to format the response the way you want.

First call startactivity() then use finish()

I listed dates of 2 Weeks later. You can use variable @period OR function datediff(dd, @date_start, @date_end)

declare @period INT, @date_start datetime, @date_end datetime, @i int;

set @period = 14
set @date_start = convert(date,DATEADD(D, -@period, curent_timestamp))
set @date_end = convert(date,current_timestamp)
set @i = 1

create table #datesList(dts datetime)
insert into #datesList values (@date_start)
while @i <= @period
    Begin
        insert into #datesList values (dateadd(d,@i,@date_start))
        set @i = @i + 1
    end
select cast(dts as DATE) from #datesList
Drop Table #datesList

If you want to log a stacktrace without involving an exception just do this:

String message = "";

for(StackTraceElement stackTraceElement : Thread.currentThread().getStackTrace()) {                         
    message = message + System.lineSeparator() + stackTraceElement.toString();
}   
log.warn("Something weird happened. I will print the the complete stacktrace even if we have no exception just to help you find the cause" + message);

Concepts

Observables in short tackles asynchronous processing and events. Comparing to promises this could be described as observables = promises + events.

What is great with observables is that they are lazy, they can be canceled and you can apply some operators in them (like map, ...). This allows to handle asynchronous things in a very flexible way.

A great sample describing the best the power of observables is the way to connect a filter input to a corresponding filtered list. When the user enters characters, the list is refreshed. Observables handle corresponding AJAX requests and cancel previous in-progress requests if another one is triggered by new value in the input. Here is the corresponding code:

this.textValue.valueChanges
    .debounceTime(500)
    .switchMap(data => this.httpService.getListValues(data))
    .subscribe(data => console.log('new list values', data));

(textValue is the control associated with the filter input).

Here is a wider description of such use case: How to watch for form changes in Angular 2?.

There are two great presentations at AngularConnect 2015 and EggHead:

In action

In fact regarding your code, you mixed two approaches ;-) Here are they:

• Manage the observable by your own. In this case, you're responsible to call the subscribe method on the observable and assign the result into an attribute of the component. You can then use this attribute in the view for iterate over the collection:

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of result">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit, OnDestroy {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.friendsObservable = http.get('friends.json')
                    .map(response => response.json())
                    .subscribe(result => this.result = result);
     }
  
     ngOnDestroy() {
       this.friendsObservable.dispose();
     }
  }
  

  Returns from both get and map methods are the observable not the result (in the same way than with promises).

• Let manage the observable by the Angular template. You can also leverage the async pipe to implicitly manage the observable. In this case, there is no need to explicitly call the subscribe method.

  @Component({
    template: `
      <h1>My Friends</h1>
      <ul>
        <li *ngFor="#frnd of (result | async)">
          {{frnd.name}} is {{frnd.age}} years old.
        </li>
      </ul>
    `,
    directive:[CORE_DIRECTIVES]
  })
  export class FriendsList implement OnInit {
    result:Array<Object>; 
  
    constructor(http: Http) {
    }
  
    ngOnInit() {
      this.result = http.get('friends.json')
                    .map(response => response.json());
     }
  }
  

You can notice that observables are lazy. So the corresponding HTTP request will be only called once a listener with attached on it using the subscribe method.

You can also notice that the map method is used to extract the JSON content from the response and use it then in the observable processing.

Hope this helps you, Thierry

Import mplot3d whole to use "projection = '3d'".

Insert the command below in top of your script. It should run fine.

from mpl_toolkits import mplot3d

I couldn't hide the separator on a specific cell except using the following workaround

- (void)layoutSubviews {
    [super layoutSubviews];
    [self hideCellSeparator];
}
// workaround
- (void)hideCellSeparator {
    for (UIView *view in  self.subviews) {
        if (![view isKindOfClass:[UIControl class]]) {
            [view removeFromSuperview];
        }
    }
}

You can also try this way:

<?php
   echo "<script>console.log('$variableName')</script>";
?>

UPDATE: you don't need to convert your values afterwards, you can do it on-the-fly when reading your CSV:

In [165]: df=pd.read_csv(url, index_col=0, na_values=['(NA)']).fillna(0)

In [166]: df.dtypes
Out[166]:
GeoName                    object
ComponentName              object
IndustryId                  int64
IndustryClassification     object

If you need to convert multiple columns to numeric dtypes - use the following technique:

Sample source DF:

In [271]: df
Out[271]:
     id    a  b  c  d  e    f
0  id_3  AAA  6  3  5  8    1
1  id_9    3  7  5  7  3  BBB
2  id_7    4  2  3  5  4    2
3  id_0    7  3  5  7  9    4
4  id_0    2  4  6  4  0    2

In [272]: df.dtypes
Out[272]:
id    object
a     object
b      int64
c      int64
d      int64
e      int64
f     object
dtype: object

Converting selected columns to numeric dtypes:

In [273]: cols = df.columns.drop('id')

In [274]: df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')

In [275]: df
Out[275]:
     id    a  b  c  d  e    f
0  id_3  NaN  6  3  5  8  1.0
1  id_9  3.0  7  5  7  3  NaN
2  id_7  4.0  2  3  5  4  2.0
3  id_0  7.0  3  5  7  9  4.0
4  id_0  2.0  4  6  4  0  2.0

In [276]: df.dtypes
Out[276]:
id     object
a     float64
b       int64
c       int64
d       int64
e       int64
f     float64
dtype: object

PS if you want to select all string (object) columns use the following simple trick:

cols = df.columns[df.dtypes.eq('object')]

We faced this issue, when the windowsuser detaching the database and windowsuser attaching the database are different. When the windowsuser detaching the database, tried to attach it, it worked fine without issues.

MSDN: ROW_NUMBER (Transact-SQL)

Returns the sequential number of a row within a partition of a result set, starting at 1 for the first row in each partition.

The following example returns rows with numbers 50 to 60 inclusive in the order of the OrderDate.

WITH OrderedOrders AS
(
    SELECT
        ROW_NUMBER() OVER(ORDER BY FirstName DESC) AS RowNumber, 
        FirstName, LastName, ROUND(SalesYTD,2,1) AS "Sales YTD"
    FROM [dbo].[vSalesPerson]
) 
SELECT RowNumber, 
    FirstName, LastName, Sales YTD 
FROM OrderedOrders 
WHERE RowNumber > 50 AND RowNumber < 60;

  RowNumber FirstName    LastName               SalesYTD

Archive process (using Xcode 8.3.2)

Note : If you are using creating IPA using drag-and-drop process using iTunes Mac app then this is no longer applicable for iTunes 12.7 since there is no built-in App store in iTunes 12.7.

1. Select ‘Generic iOS Device’ on device list in Xcode

2. Clean the project (cmd + shift + k as shortcut)

3. Go to Product -> Archive your project

4. Once archive is succeeded this will open a window with archived project

5. You can validate your archive by pressing Validate (optional step but recommended)

6. Now press on Export button

7. This will open list of method for export. Select the export method as per your requirement and click on Next button.

8. This will show list of team for provisioning. Select accordingly and press on ‘Choose’ button.

9. Now you’ve to select Device support -> Export one app for all compatible devices (recommended). If you want IPA for specific device then select the device variant from list and press on ‘Next’ button.

10. Now you’ll be able to see the ‘Summary’ and then press on ‘Next’ button

11. Thereafter IPA file generation beings and later you’ll be able to export the IPA as [App Name - Date Time] and then press on ‘Done’.

Must Read This (how-do-the-bitwise-shift-operators-work)

based on other answers this is my current working implementation, which retrieves nested xml files in a root directory:

files = []
for root, dirnames, filenames in os.walk(myDir):
    files.extend(glob.glob(root + "/*.xml"))

I'm really having fun with python :)

The accepted answer here is a bit dated. As of April 2020, a recommended approach seen on the MDN website suggests using FormData and also does not ask to set the content type. https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

I'm quoting the code snippet for convenience:

const formData = new FormData();
const fileField = document.querySelector('input[type="file"]');

formData.append('username', 'abc123');
formData.append('avatar', fileField.files[0]);

fetch('https://example.com/profile/avatar', {
  method: 'PUT',
  body: formData
})
.then((response) => response.json())
.then((result) => {
  console.log('Success:', result);
})
.catch((error) => {
  console.error('Error:', error);
});

You cannot drop a database currently being used however you can use sp_detach_db stored procedure if you want to remove a database from the server without deleting the database files.

Here u Go

f = open('test.txt','rb+')
ch=f.read(1)
ch=str(ch,'utf-8')
print(ch)

I dont do it like this. I find it easier to overload the constructor of the asychtask class ..

public class calc_stanica extends AsyncTask>

String String mWhateveryouwantToPass;

 public calc_stanica( String whateveryouwantToPass)
{

    this.String mWhateveryouwantToPass = String whateveryouwantToPass;
}
/*Now you can use  whateveryouwantToPass in the entire asynchTask ... you could pass in a context to your activity and try that too.*/   ...  ...  

float(str(round(answer, 2)))
float(str(round(0.0556781255, 2)))

You just put them in __init__.py.

So with test/classes.py being:

class A(object): pass
class B(object): pass

... and test/__init__.py being:

from classes import *

class Helper(object): pass

You can import test and have access to A, B and Helper

>>> import test
>>> test.A
<class 'test.classes.A'>
>>> test.B
<class 'test.classes.B'>
>>> test.Helper
<class 'test.Helper'>

Step 1: Create a maven project in Eclipse and add the below dependency in the pom.xml

<dependencies>
  <dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.18</version>
</dependency>

Step 2: Run As --> Configuraitons --> Goto Arguments --> give arguments like below maven -clean install

Step 3: Run As --> maven clean

Once you do the maven clean you see Build Success and lombok jar file in the maven Dependencies

Step 4: Goto the jar location as shown in the below screen shot.

Step 5: Give command as shown like below after reaching in the .m2 folder

Step 6: Locate where is your eclipse folder once you this window.Once you see Install Successfull message click on Quit Installer option at the bottom.

Step 7 : We have finished installing the lombok.jar successfully .Now restart your Eclipse IDE and Start below Sample Code to check whether the data is coming or not in the getters and setters.

Step 8: Open Eclipse and create simple Java Maven project and see in the Outline section you can see getters and setters are created you can use either @Data or @Getter @Setter On top of class or you can give on top of variable

@Getter @Setter
privateString riverName;

{OR}

@Getter
@Setter
Class River{
String riverName;
}

[OR]

@Data
class River 
{
Private String riverName;

}

You can see the project structure and Outline Structure how it got created in simple steps.

There is already a command in the ssh suite to do this automatically for you. I.e log into a remote host and add the public key to that computers authorized_keys file.

ssh-copy-id -i /path/to/key/file [email protected]

If the key you are installing is ~/.ssh/id_rsa then you can even drop the -i flag completely.

Much better than manually doing it!

Install Aptana plugin to your Eclipse installation.

It has built-in FTP support, and it works excellently.

You can:

• Edit files directly from the FTP server
• Perform file/folder management (copy, delete, move, rename, etc.)
• Upload/download files to/from FTP server
• Synchronize local files with FTP server. You can make several profiles (actually projects) for this so you won't have to reinput over and over again.

As a matter of fact the FTP support is so good I'm using Aptana (or Eclipse + Aptana) now for all my FTP needs. Plus I get syntax highlighting/whatever coding support there is. Granted, Eclipse is not the speediest app to launch, but it doesn't bug me so much.

The best plain English explanation comes from using an analogy:

• Web pages allow people to communicate and collaborate with each other.
• Web services allow programs to communicate and collaborate with each other.

Your PHP example is a web service by that definition, because the output could be consumed by another program. But in reality, HTML screen-scraping is not a reliable or maintainable way of producing web services.

from the docs

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

i applied the .navbar-text class to my <li> element, so the result is

<li class="nav-item navbar-text">

this centers the links vertically with respect to my navbar-brand img

you are going to want to separate your arguments into separate parameter

$msbuild = "C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe"
$arguments = "/v:q /nologo"
start-process $msbuild $arguments 

The layout to use is indeed "2006-01-02T15:04:05.000Z" described in RickyA's answer.
It isn't "the time of the first commit of go", but rather a mnemonic way to remember said layout.
See pkg/time:

The reference time used in the layouts is:

Mon Jan 2 15:04:05 MST 2006

which is Unix time 1136239445.
Since MST is GMT-0700, the reference time can be thought of as

 01/02 03:04:05PM '06 -0700

(1,2,3,4,5,6,7, provided you remember that 1 is for the month, and 2 for the day, which is not easy for an European like myself, used to the day-month date format)

As illustrated in "time.parse : why does golang parses the time incorrectly?", that layout (using 1,2,3,4,5,6,7) must be respected exactly.

In Symfony forms, there are two different types of transformers and three different types of underlying data: In any form, the three different types of data are:

• Model data

  This is the data in the format used in your application (e.g. an Issue object). If you call Form::getData() or Form::setData(), you're dealing with the "model" data.

• Norm Data

  This is a normalized version of your data and is commonly the same as your "model" data (though not in our example). It's not commonly used directly.

• View Data

  This is the format that's used to fill in the form fields themselves. It's also the format in which the user will submit the data. When you call Form::submit($data), the $data is in the "view" data format.

The two different types of transformers help convert to and from each of these types of data:

• Model transformers:

  transform(): "model data" => "norm data"
  reverseTransform(): "norm data" => "model data"

• View transformers:

  transform(): "norm data" => "view data"
  reverseTransform(): "view data" => "norm data"

Which transformer you need depends on your situation.

To use the view transformer, call addViewTransformer().

If you want to get all form data:

$form->getData();

If you are after a specific form field (for example first_name):

$form->get('first_name')->getData();

!important, after your CSS declaration.

div {
   color: blue !important; 

   /* This Is Now Working */
}

Is this what you're looking for?

if (request instanceof HttpServletRequest) {
 String url = ((HttpServletRequest)request).getRequestURL().toString();
 String queryString = ((HttpServletRequest)request).getQueryString();
}

To Reconstruct:

System.out.println(url + "?" + queryString);

Info on HttpServletRequest.getRequestURL() and HttpServletRequest.getQueryString().

There are two ways to go about this:

I recommend the first option initially, due to its ease of implementation. Once you mature in your build processes, switch over to the second.

1. Poll the repository to see if changes occurred. This might "skip" a commit if two commits come in within the same polling interval. Description of how to do so here, note the fourth screenshot where you configure on the job a "build trigger" based on polling the repository (with a crontab-like configuration).

2. Configure your repository to have a post-commit hook which notifies Jenkins that a build needs to start. Description of how to do so here, in the section "post-commit hooks"

The SVN Tag feature is not part of the polling, it is part of promoting the current "head" of the source code to a tag, to snapshot a build. This allows you to refer to Jenkins buid #32 as SVN tag /tags/build-32 (or something similar).

For .NET Core, add System.Configuration.ConfigurationManager from NuGet manager.
And read appSetting from App.config

<appSettings>
  <add key="appSetting1" value="1000" />
</appSettings>

Add System.Configuration.ConfigurationManager from NuGet Manager

ConfigurationManager.AppSettings.Get("appSetting1")

Off the top of my head:

float fl = 0.678;
int rounded_f = (int)(fl+0.5f);

I'm a little surprised it doesn't just do that. Could there another element inside the div that has a width set to something greater than 250?

I was trying to concatenate three .mp3 audio files into one .m4a file and this ffmpeg command works.

Input command:

ffmpeg -i input1.mp3 -i input2.mp3 -i input3.mp3 \
       -filter_complex "concat=n=3:v=0:a=1" -f MOV -vn -y input.m4a

Meanings of : -filter_complex "concat=n=3:v=0:a=1" :

concat means use the media concatenate (joining) function.
n means confirm total count of input files.
v means has video? use 0 = no video, 1 = contains video.
a means has audio? use 0 = no audio, 1 = contain audio.
-f means force set file format (to see all supported formats, use ffmpeg -formats)
-vn means disable video (and also -an would disable audio if not wanted)
-y means overwrite output files (if the output file already exists).

For more info: use ffmpeg -h full print all options (including all format and codec specific options, very long)

If you are on a OS X, this probably has nothing to do with the sed command. On the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code.

Try adding the -e argument explicitly and giving '' as argument to -i:

find ./ -type f -exec sed -i '' -e "s/192.168.20.1/new.domain.com/" {} \;

See this.

src is to used to add that resource to the page, whereas href is used to link to a particular resource from that page.

When you use in your webpage, the browser sees that its a style sheet and hence continues with the page rendering as the style sheet is downloaded in parellel.

When you use in your webpage, it tells the browser to insert the resource at the location. So now the browser has to fetch the js file and then loads it. Until the browser finishes the loading process, the page rendering process is halted. That is the reason why YUI recommends to load your JS files at the very bottom of your web page.

For Windows users, you can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there. The JVM should be able to grab the virtual machine options from _JAVA_OPTIONS.

I use a combination of json.get() and instanceof to read in values that might be either integers or integer strings.

These three test cases illustrate:

int val;
Object obj;
JSONObject json = new JSONObject();
json.put("number", 1);
json.put("string", "10");
json.put("other", "tree");

obj = json.get("number");
val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
System.out.println(val);

obj = json.get("string");
val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
System.out.println(val);

try {
    obj = json.get("other");
    val = (obj instanceof Integer) ? (int) obj : (int) Integer.parseInt((String) obj);
} catch (Exception e) {
    // throws exception
}

Simply put, hash-based collections aren't indexed so you have to do it manually.

Use the global flag.

I worked on Zingd idea and made it simpler to use.

I also added the standard F11 key to toggle fullscreen mode.

Setup

Everything is now in the FullScreen class, so you don't have to declare a bunch of variables in your Form. You just instanciate a FullScreen object in your form's constructor :

FullScreen fullScreen;

public Form1()
{
    InitializeComponent();
    fullScreen = new FullScreen(this);
}

Please note this assumes the form is not maximized when you create the FullScreen object.

Usage

You just use one of the classe's functions to toggle the fullscreen mode :

fullScreen.Toggle();

or if you need to handle it explicitly :

fullScreen.Enter();
fullScreen.Leave();

Code

using System.Windows.Forms;


class FullScreen
{ 
    Form TargetForm;

    FormWindowState PreviousWindowState;

    public FullScreen(Form targetForm)
    {
        TargetForm = targetForm;
        TargetForm.KeyPreview = true;
        TargetForm.KeyDown += TargetForm_KeyDown;
    }

    private void TargetForm_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyData == Keys.F11)
        {
            Toggle();
        }
    }

    public void Toggle()
    {
        if (TargetForm.WindowState == FormWindowState.Maximized)
        {
            Leave();
        }
        else
        {
            Enter();
        }
    }
        
    public void Enter()
    {
        if (TargetForm.WindowState != FormWindowState.Maximized)
        {
            PreviousWindowState = TargetForm.WindowState;
            TargetForm.WindowState = FormWindowState.Normal;
            TargetForm.FormBorderStyle = FormBorderStyle.None;
            TargetForm.WindowState = FormWindowState.Maximized;
        }
    }
      
    public void Leave()
    {
        TargetForm.FormBorderStyle = FormBorderStyle.Sizable;
        TargetForm.WindowState = PreviousWindowState;
    }
}

Contanis occur if using the method of the present letter, and store the corresponding number using the IndexOf method, see example below.

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim myString As String = "abcdef"
    Dim numberString As String = String.Empty

    If myString.Contains("d") Then
        numberString = myString.IndexOf("d")
    End If
End Sub

Another sample with TextBox

  Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim myString As String = "abcdef"
    Dim numberString As String = String.Empty

    If myString.Contains(me.TextBox1.Text) Then
        numberString = myString.IndexOf(Me.TextBox1.Text)
    End If
End Sub

There is a lot of excellent information here. Unfortunately a lot of this fling-processing code is scattered around on various sites in various states of completion, even though one would think this is essential to many applications.

I've taken the time to create a fling listener that verifies that the appropriate conditions are met. I've added a page fling listener that adds more checks to ensure that flings meet the threshold for page flings. Both of these listeners allow you to easily restrict flings to the horizontal or vertical axis. You can see how it's used in a view for sliding images. I acknowledge that the people here have done most of the research---I've just put it together into a usable library.

These last few days represent my first stab at coding on Android; expect much more to come.

UPDATE 24.04.2016.

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)

EDIT

I've tested this on Twenty Fifteen and it's working, so it should be working for you.

In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:

    <div id="ajax-posts" class="row">
        <?php
            $postsPerPage = 3;
            $args = array(
                    'post_type' => 'post',
                    'posts_per_page' => $postsPerPage,
                    'cat' => 8
            );

            $loop = new WP_Query($args);

            while ($loop->have_posts()) : $loop->the_post();
        ?>

         <div class="small-12 large-4 columns">
                <h1><?php the_title(); ?></h1>
                <p><?php the_content(); ?></p>
         </div>

         <?php
                endwhile;
        wp_reset_postdata();
         ?>
    </div>
    <div id="more_posts">Load More</div>

This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with

$cat_id = get_query_var('cat');

This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like

<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>

And pull the category with

var cat = $('#more_posts').data('category');

But for now, you can leave this out.

Next in functions.php I added

wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
    'ajaxurl' => admin_url( 'admin-ajax.php' ),
    'noposts' => __('No older posts found', 'twentyfifteen'),
));

Right after the existing wp_localize_script. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.

At the end of the functions.php file I added the function that will load your posts:

function more_post_ajax(){

    $ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
    $page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;

    header("Content-Type: text/html");

    $args = array(
        'suppress_filters' => true,
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'cat' => 8,
        'paged'    => $page,
    );

    $loop = new WP_Query($args);

    $out = '';

    if ($loop -> have_posts()) :  while ($loop -> have_posts()) : $loop -> the_post();
        $out .= '<div class="small-12 large-4 columns">
                <h1>'.get_the_title().'</h1>
                <p>'.get_the_content().'</p>
         </div>';

    endwhile;
    endif;
    wp_reset_postdata();
    die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.

If you've added your category in the loader, you'd add:

$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';

And instead of 8, you'd put $cat. This will be in the $_POST array, and you'll be able to use it in ajax.

Last part is the ajax itself. In functions.js I put inside the $(document).ready(); enviroment

var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;


function load_posts(){
    pageNumber++;
    var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
    $.ajax({
        type: "POST",
        dataType: "html",
        url: ajax_posts.ajaxurl,
        data: str,
        success: function(data){
            var $data = $(data);
            if($data.length){
                $("#ajax-posts").append($data);
                $("#more_posts").attr("disabled",false);
            } else{
                $("#more_posts").attr("disabled",true);
            }
        },
        error : function(jqXHR, textStatus, errorThrown) {
            $loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
        }

    });
    return false;
}

$("#more_posts").on("click",function(){ // When btn is pressed.
    $("#more_posts").attr("disabled",true); // Disable the button, temp.
    load_posts();
});

Saved it, tested it, and it works :)

Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD

UPDATE

For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;) you can try with

$(window).on('scroll', function () {
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

This should run the load_posts() function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer

$(window).on('scroll', function(){
    if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
        if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
                load_posts();
        }
    }
});

Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100 or $('footer').offset().top for some reason. If that should happen, just increase the number where the scroll goes to.

You can easily check it by putting console.logs in your code and see in the inspector what they throw out

$(window).on('scroll', function () {
    console.log($(window).scrollTop() + $(window).height());
    console.log($(document).height() - 100);
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

And just adjust accordingly ;)

Hope this helps :) If you have any questions just ask.

I used this to access the ID in my component:

<Route path="/details/:id" component={DetailsPage}/>

And in the detail component:

export default class DetailsPage extends Component {
  render() {
    return(
      <div>
        <h2>{this.props.match.params.id}</h2>
      </div>
    )
  }
}

This will render any ID inside an h2, hope that helps someone.

You don't really need to install or use any third party tools.

The drivers located in ...\Android\Sdk\extras\google\usb_driver work just fine.

Step 1: In Device Manager, Right click on the malfunctioning Android ADB Interface driver

Step 2: Select Update Driver Software

Step 3: Select Browse my computer for driver software

Step 4: Select Let me pick from a list of device drivers on my computer

Step 5: Select Have Disk

This window pops up:

Step 6: Copy the location of the Google USB Driver (...\Android\Sdk\extras\google\usb_driver) or browse to it.

Step 7: Click Ok

This window pops up:

Step 8: Select Android ADB Interface and click Next

The window below pops up with a warning:

That's it. You driver installation will start and in a few seconds, you should be able to see your device

dependencies {

    compile 'com.android.support:appcompat-v7:23.0.0'

}

This worked for me... in Android Studio...

/usr/bin/java_home tool returns 1 if java not installed.

So you can check if java is installed by the next way:

/usr/libexec/java_home &> /dev/null && echo "installed" || echo  "not installed"

Without telling us what language this dll/assembly is from, we can only guess.

So how about .NET Reflector

This should do the trick:

$ echo "$var" | awk -F':' '{print $NF}'
/home/some/directory/file

One way of doing this is via an exists clause:

select * from genes g
where exists
(select null from genes g1
 where g.locus = g1.locus and g.chromosome = g1.chromosome and g.id <> g1.id)

Alternatively, in MySQL you can get a summary of all matching ids with a single table access, using group_concat:

select group_concat(id) matching_ids, chromosome, locus 
from genes
group by chromosome, locus
having count(*) > 1

-z string True if the string is null (an empty string)

At first, you need to add : after the IP address to indicate the path is following:

scp magento.tar.gz [email protected]:/var/www

I don't think you need to sudo the scp. In this case it doesn't affect the remote machine, only the local command.

Then if your user@xx.x.x.xx doesn't have write access to /var/www then you need to do it in 2 times:

Copy to remote server in your home folder (: represents your remote home folder, use :subfolder/ if needed, or :/home/user/ for full path):

scp magento.tar.gz [email protected]:

Then SSH and move the file:

ssh [email protected]
sudo mv magento.tar.gz /var/www

OK! I'm really sorry to those that have actually submitted comments and answers, but I found the problem. I don't think this will help a lot of others trying to track down their personal SIGSEGV, but mine (and it was very hard) was entirely related to this:

https://code.google.com/p/android/issues/detail?id=8709

The libcrypto.so in my dump kind of clued me in. I do a MD5 hash of packet data when trying to determine if I've already seen the packet, and skipping it if I had. I thought at one point this was an ugly threading issue related to tracking those hashes, but it turned out it was the java.security.MessageDigest class! It's not thread safe!

I swapped it out with a UID I was stuffing in every packet based on the device UUID and a timestamp. No problems since.

I guess the lesson I can impart to those that were in my situation is, even if you're a 100% Java application, pay attention to the native library and symbol noted in the crash dump for clues. Googling for SIGSEGV + the lib .so name will go a lot farther than the useless code=1, etc... Next think about where your Java app could touch native code, even if it's nothing you're doing. I made the mistake of assuming it was a Service + UI threading issue where the Canvas was drawing something that was null, (the most common case I Googled on SIGSEGV) and ignored the possibility it could have been completely related to code I wrote that was related to the lib .so in the crash dump. Naturally java.security would use a native component in libcrypto.so for speed, so once I clued in, I Googled for Android + SIGSEGV + libcrypto.so and found the documented issue. Good luck!

This Python snippet will git mv --force all files in a directory to be lowercase. For example, foo/Bar.js will become foo/bar.js via git mv foo/Bar.js foo/bar.js --force.

Modify it to your liking. I just figured I'd share :)

import os
import re

searchDir = 'c:/someRepo'
exclude = ['.git', 'node_modules','bin']
os.chdir(searchDir)

for root, dirs, files in os.walk(searchDir):
    dirs[:] = [d for d in dirs if d not in exclude]
    for f in files:
        if re.match(r'[A-Z]', f):
            fullPath = os.path.join(root, f)
            fullPathLower = os.path.join(root, f[0].lower() + f[1:])
            command = 'git mv --force ' + fullPath + ' ' + fullPathLower
            print(command)
            os.system(command)

SELECT COALESCE(
    (SELECT SUM(Price) AS TotalPrice 
    FROM Inventory
    WHERE (DateAdded BETWEEN @StartDate AND @EndDate))
    , 0)

If the table has rows in the response it returns the SUM(Price). If the SUM is NULL or there are no rows it will return 0.

Putting COALESCE(SUM(Price), 0) does NOT work in MSSQL if no rows are found.

I have to offer this as a better approach - you don't always have the luxury of an identity field:

UPDATE m
SET [status]=10
FROM (
  Select TOP (10) *
  FROM messages
  WHERE [status]=0
  ORDER BY [priority] DESC
) m

You can also make the sub-query as complicated as you want - joining multiple tables, etc...

Why is this better? It does not rely on the presence of an identity field (or any other unique column) in the messages table. It can be used to update the top N rows from any table, even if that table has no unique key at all.

 String s1="[a,b,c,d]";
 String replace = s1.replace("[","");
 System.out.println(replace);
 String replace1 = replace.replace("]","");
 System.out.println(replace1);
 List<String> myList = new ArrayList<String>(Arrays.asList(replace1.split(",")));
 System.out.println(myList.toString());

It's a placeholder for the first parameter, which in your case evaluates to "wordpad.exe".

If you had an additional parameter, you'd use {1}, etc.

You have a company and there is only 1 worker but you got 1 new project at that time you hire new candidate -- this is horizontal scaling. where new candidate is new machines and project is new traffic/calls to your api's.

Where as 1 project with an IIT/NIT guy handling all request to your api/traffic. If any time more request to your api's then fire him and replacing him with a high IQ NIT/IIT guy -- this is vertical scaling.

If scope resolution :: had to be used outside the class then the respective function or variable should be declared as static

class Foo { 
        //Static variable 
        public static $static_var = 'static variable'; 
        //Static function 
        static function staticValue() { return 'static function'; } 

        //function 
        function Value() { return 'Object'; } 
} 



 echo Foo::$static_var . "<br/>"; echo Foo::staticValue(). "<br/>"; $foo = new Foo(); echo $foo->Value();

There is a major error in the tutorials destined for newbies here: http://developer.android.com/training/basics/actionbar/styling.html

It is major because it is almost impossible to detect cause of error for a newbie.

The error is that this tutorial explicitly states that the tutorial is valid for api level 11 (Android 3.0), while in reality this is only true for the theme Theme.Holo (without further extensions and variants)

But this tutorial uses the the theme Theme.holo.Light.DarkActionBar which is only a valid theme from api level 14 (Android 4.0) and above.

This is only one of many examples on errors found in these tutorials (which are great in other regards). Somebody should correct these errors this weekend because they are really costly and annoying timethieves. If there is a way I can send this info to the Android team, then please tell me and I will do it. Hopefully, however, they read Stackoverflow. (let me suggest: The Android team should consider to put someone newbie to try out all tutorials as a qualification that they are valid).

Another error I (and countless other people) have found is that the appcombat backward compliance module really is not working if you strictly follow the tutorials. Error unknown. I had to give up.

Regarding the error in this thread, here is a quote from the tutorial text with italics on the mismatch:

" For Android 3.0 and higher only

When supporting Android 3.0 and higher only, you can define the action bar's background like this:

    <resources>
        <!-- the theme applied to the application or activity -->
        <style name="CustomActionBarTheme"
        parent="@style/Theme.Holo.Light.DarkActionBar"> 

ERROR1: Only Theme.Holo can be used with Android 3.0. Therefore, remove the "Light.DarkActionBar etc.

ERROR2: @style/Theme.Holo"> will not work. It is necessary to write @android:style/Theme.Holo">in order to indicate that it is a built in Theme that is being referenced. (A bit strange that "built in" is not the default, but needs to be stated?)

The compiler advice for error correction is to define api level 14 as minimum sdk. This is not optimal because it creates incompliance to Andreoid 3.0 (api level 11). Therefore, I use Theme.Holo only and this seems to work fine (a fresh finding, though).

I am using Netbeans with Android support. Works nicely.

Use any JDK installation as long as it is NOT 64bit. The easiest way to find out if it is 64bit installation is to check the folder it resides into. e.g.

C:\Program Files\... is for 64 bit programs
C:\Program Files (x86)\... is for 32 bit programs

#define CTTimeStart() NSDate * __date = [NSDate date]
#define CTTimeEnd(MSG) NSLog(MSG " %g",[__date timeIntervalSinceNow]*-1)

Usage:

CTTimeStart();
...
CTTimeEnd(@"that was a long time:");

Output:

2013-08-23 15:34:39.558 App-Dev[21229:907] that was a long time: .0023

I uninstalled xampp, deleted everything under the c:\xampp folder, then reinstalled xampp as administrator and it worked like a charm.

Used pip3 install <package> instead and solved the permission problem with pip.

MySQL v5.5.3 and greater:

Just add three lines only in the [mysqld] section:

[mysqld]
character-set-server = utf8
collation-server = utf8_unicode_ci
skip-character-set-client-handshake

Note: Including skip-character-set-client-handshake here obviates the need to include both init-connect in [mysqld] and default-character-set in the [client] and [mysql] sections.

For old-school CD keys, it was just a matter of making up an algorithm for which CD keys (which could be any string) are easy to generate and easy to verify, but the ratio of valid-CD-keys to invalid-CD-keys is so small that randomly guessing CD keys is unlikely to get you a valid one.

INCORRECT WAY TO DO IT:

Starcraft and Half-life both used the same checksum, where the 13th digit verified the first 12. Thus, you could enter anything for the first 12 digits, and guess the 13th (there's only 10 possibilities), leading to the infamous 1234-56789-1234

The algorithm for verifying is public, and looks something like this:

x = 3;
for(int i = 0; i < 12; i++)
{
    x += (2 * x) ^ digit[i];
}
lastDigit = x % 10;

CORRECT WAY TO DO IT

Windows XP takes quite a bit of information, encrypts it, and puts the letter/number encoding on a sticker. This allowed MS to both verify your key and obtain the product-type (Home, Professional, etc.) at the same time. Additionally, it requires online activation.
The full algorithm is rather complex, but outlined nicely in this (completely legal!) paper, published in Germany.

Of course, no matter what you do, unless you are offering an online service (like World of Warcraft), any type of copy protection is just a stall: unfortunately, if it's any game worth value, someone will break (or at least circumvent) the CD-key algorithm, and all other copyright protections.

REAL CORRECT WAY TO DO IT:

For online-services, life is a bit simpler, since even with the binary file you need to authenticate with their servers to make any use of it (eg. have a WoW account). The CD-key algorithm for World of Warcraft - used, for instance, when buying playtime cards - probably looks something like this:

1. Generate a very large cryptographically-secure random number.
2. Store it in our database and print it on the card.
   
   Then, when someone enters a playtime-card number, check if it's in the database, and if it is, associate that number with the current user so it can never be used again.

For online services, there is no reason not to use the above scheme; using anything else can lead to problems.

I am experiencing the same problem right now. According to this post you need to have a C Compiler or GCC. I'll try to fix the problem by installing C compiler. I'll inform you if it works (we'll I guess you don't need it anymore, but I'll post the result anyway) :)

You need to convert your private key to PKCS8 format using following command:

openssl pkcs8 -topk8 -inform PEM -outform DER -in private_key_file  -nocrypt > pkcs8_key

After this your java program can read it.

• Remove the file from the index, but keep it versioned and left with uncommitted changes in working copy:

  git reset head <file>
  

• Reset the file to the last state from HEAD, undoing changes and removing them from the index:

  git reset HEAD <file>
  git checkout <file>
  
  # If you have a `<branch>` named like `<file>`, use:
  git checkout -- <file>
  

  This is needed since git reset --hard HEAD won't work with single files.

• Remove <file> from index and versioning, keeping the un-versioned file with changes in working copy:

  git rm --cached <file>
  

• Remove <file> from working copy and versioning completely:

  git rm <file>
  

If you just want the difference in years, there's:

SELECT EXTRACT(YEAR FROM date1) - EXTRACT(YEAR FROM date2) FROM mytable

Or do you want fractional years as well?

SELECT (date1 - date2) / 365.242199 FROM mytable

365.242199 is 1 year in days, according to Google.

I don't know if it is help. Create an AVD for a tablet-type device: Set the target to "Android 3.0" and the skin to "WXGA" (the default skin). You can check this site. http://developer.android.com/guide/practices/optimizing-for-3.0.html

Try this:

function validate() {
  var remember = document.getElementById("remember");
  if (remember.checked) {
    alert("checked");
  } else {
    alert("You didn't check it! Let me check it for you.");
  }
}

Your script doesn't know what the variable remember is. You need to get the element first using getElementById().

a simple moving average for 10 items, using a list:

#include <list>

std::list<float> listDeltaMA;

float getDeltaMovingAverage(float delta)
{
    listDeltaMA.push_back(delta);
    if (listDeltaMA.size() > 10) listDeltaMA.pop_front();
    float sum = 0;
    for (std::list<float>::iterator p = listDeltaMA.begin(); p != listDeltaMA.end(); ++p)
        sum += (float)*p;
    return sum / listDeltaMA.size();
}

map(float, mylist) should do it.

(In Python 3, map ceases to return a list object, so if you want a new list and not just something to iterate over, you either need list(map(float, mylist) - or use SilentGhost's answer which arguably is more pythonic.)

location.href does not work in chrome when called through the body/window unload event

Can brackets be nested?

If not: \[([^]]+)\] matches one item, including square brackets. Backreference \1 will contain the item to be match. If your regex flavor supports lookaround, use

(?<=\[)[^]]+(?=\])

This will only match the item inside brackets.

I'll answer this question in Go because Go does not have a rich a lot of collections in its standard library.

Since a stack is really easy to implement I thought I'd try and use two stacks to accomplish a double ended queue. To better understand how I arrived at my answer I've split the implementation in two parts, the first part is hopefully easier to understand but it's incomplete.

type IntQueue struct {
    front       []int
    back        []int
}

func (q *IntQueue) PushFront(v int) {
    q.front = append(q.front, v)
}

func (q *IntQueue) Front() int {
    if len(q.front) > 0 {
        return q.front[len(q.front)-1]
    } else {
        return q.back[0]
    }
}

func (q *IntQueue) PopFront() {
    if len(q.front) > 0 {
        q.front = q.front[:len(q.front)-1]
    } else {
        q.back = q.back[1:]
    }
}

func (q *IntQueue) PushBack(v int) {
    q.back = append(q.back, v)
}

func (q *IntQueue) Back() int {
    if len(q.back) > 0 {
        return q.back[len(q.back)-1]
    } else {
        return q.front[0]
    }
}

func (q *IntQueue) PopBack() {
    if len(q.back) > 0 {
        q.back = q.back[:len(q.back)-1]
    } else {
        q.front = q.front[1:]
    }
}

It's basically two stacks where we allow the bottom of the stacks to be manipulated by each other. I've also used the STL naming conventions, where the traditional push, pop, peek operations of a stack have a front/back prefix whether they refer to the front or back of the queue.

The issue with the above code is that it doesn't use memory very efficiently. Actually, it grows endlessly until you run out of space. That's really bad. The fix for this is to simply reuse the bottom of the stack space whenever possible. We have to introduce an offset to track this since a slice in Go cannot grow in the front once shrunk.

type IntQueue struct {
    front       []int
    frontOffset int
    back        []int
    backOffset  int
}

func (q *IntQueue) PushFront(v int) {
    if q.backOffset > 0 {
        i := q.backOffset - 1
        q.back[i] = v
        q.backOffset = i
    } else {
        q.front = append(q.front, v)
    }
}

func (q *IntQueue) Front() int {
    if len(q.front) > 0 {
        return q.front[len(q.front)-1]
    } else {
        return q.back[q.backOffset]
    }
}

func (q *IntQueue) PopFront() {
    if len(q.front) > 0 {
        q.front = q.front[:len(q.front)-1]
    } else {
        if len(q.back) > 0 {
            q.backOffset++
        } else {
            panic("Cannot pop front of empty queue.")
        }
    }
}

func (q *IntQueue) PushBack(v int) {
    if q.frontOffset > 0 {
        i := q.frontOffset - 1
        q.front[i] = v
        q.frontOffset = i
    } else {
        q.back = append(q.back, v)
    }
}

func (q *IntQueue) Back() int {
    if len(q.back) > 0 {
        return q.back[len(q.back)-1]
    } else {
        return q.front[q.frontOffset]
    }
}

func (q *IntQueue) PopBack() {
    if len(q.back) > 0 {
        q.back = q.back[:len(q.back)-1]
    } else {
        if len(q.front) > 0 {
            q.frontOffset++
        } else {
            panic("Cannot pop back of empty queue.")
        }
    }
}

It's a lot of small functions but of the 6 functions 3 of them are just mirrors of the other.

Don't let white space fool you. Just test this in a console browser.

Use native javascript. Here is and example with two 'ul' sets with the same class. You don't need to have your 'ul' list all in one line to avoid white space just use your array count to jump over white space.

How to get around white space with querySelector() then childNodes[] js fiddle link: https://jsfiddle.net/aparadise/56njekdo/

var y = document.querySelector('.list');
var myNode = y.childNodes[11].style.backgroundColor='red';

<ul class="list">
    <li>8</li>
    <li>9</li>
    <li>100</li>
</ul>

<ul class="list">
    <li>ABC</li>
    <li>DEF</li>
    <li>XYZ</li>
</ul>

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

I think you (meant)want an list with the first 30 cells already filled. So

   f = []

   for i in range(30):
       f.append(0)

An example to where this could be used is in Fibonacci sequence. See problem 2 in Project Euler

Because growthRates is a sequence (you're even iterating it!) and you multiply it by (1 + 0.01), which is obviously a float (1.01). I guess you mean for growthRate in growthRates: ... * growthrate?

you can see the result here In these simple block of code you can change the size of your image ,and make it bigger when the mouse enter over the image , and it will return to its original size when mouve leave.

html:

<div>
<img  onmouseover="fifo()" onmouseleave="fifo()" src="your_image"   
       width="10%"  id="f" >
</div>

js file:

var b=0;
function fifo() {
       if(b==0){
            document.getElementById("f").width = "300";
           b=1;
          }
       else
          {
         document.getElementById("f").width = "100";
          b=0;
        }
   }

There is additionally collections’ stream() util with Java 8

collection.forEach((temp) -> {
            System.out.println(temp);
});

or

collection.forEach(System.out::println);

More information about Java 8 stream and collections for wonderers link

#Try without dot notation
sample_dict = {'name': 'John', 'age': 29}
print(sample_dict['name']) # John
print(sample_dict['age']) # 29

It can be done like this:

import numpy as np

# create a random matrix:
A = np.random.normal(size=(5,2))

# add a column of zeros to it:
print(np.hstack((A,np.zeros((A.shape[0],1)))))

In general, if A is an m*n matrix, and you need to add a column, you have to create an n*1 matrix of zeros, then use "hstack" to add the matrix of zeros to the right of the matrix A.
