In my system (Ubuntu 12.04) I found RESET QUERY CACHE and even restarting mysql server not enough. This was due to memory disc caching.
After each query, I clean the disc cache in the terminal:

sync && echo 3 | sudo tee /proc/sys/vm/drop_caches

and then reset the query cache in mysql client:

RESET QUERY CACHE;

Fixing must override a super class method error is not difficult, You just need to change Java source version to 1.6 because from Java 1.6 @Override annotation can be used along with interface method. In order to change source version to 1.6 follow below steps :

1. Select Project , Right click , Properties
2. Select Java Compiler and check the check box "Enable project specific settings"
3. Now make Compiler compliance level to 1.6
4. Apply changes

You just need to set background and give previous.xml file in background of button in your layout file.

<Button
 android:id="@+id/button1"
 android:background="@drawable/previous"
 android:layout_width="200dp"
 android:layout_height="126dp"
 android:text="Hello" />

and done.Edit Following is previous.xml file in drawable directory

<?xml version="1.0" encoding="utf-8"?>

<item android:drawable="@drawable/onclick" android:state_selected="true"></item>
<item android:drawable="@drawable/onclick" android:state_pressed="true"></item>
<item android:drawable="@drawable/normal"></item>

I found that with spring boot 2.0.2.RELEASE, configuring spring-boot-starter-data-jpa and com.h2database in the POM file is not just enough to have H2 console working. You must configure spring-boot-devtools as below. Optionally you could follow the instruction from Aaron Zeckoski in this post

  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
 </dependency>

You can simply use this:

'07311954' in df.date.values which returns True or False

Here is the further explanation:

In pandas, using in check directly with DataFrame and Series (e.g. val in df or val in series ) will check whether the val is contained in the Index.

BUT you can still use in check for their values too (instead of Index)! Just using val in df.col_name.values or val in series.values. In this way, you are actually checking the val with a Numpy array.

And .isin(vals) is the other way around, it checks whether the DataFrame/Series values are in the vals. Here vals must be set or list-like. So this is not the natural way to go for the question.

Pattern p = Pattern.compile("[^a-z0-9 ]", Pattern.CASE_INSENSITIVE);
Matcher m = p.matcher("I am a string");
boolean b = m.find();

if (b)
   System.out.println("There is a special character in my string");

change PYTHONHOME to the parent folder of the bin file of python, like /usr,which is the parent folder of /usr/bin.

I think this is the most annoying little peculiarity of HTML... That button needs to be of type "button" in order to not submit.

<button type="button">My Button</button>

Update 5-Feb-2019: As per the HTML Living Standard (and also HTML 5 specification):

The missing value default and invalid value default are the Submit Button state.

As you are redefining the column again, you have to specify the datatype again and add auto_increment to it as it's a part of datatype.

ALTER TABLE `document` MODIFY COLUMN `document_id` INT AUTO_INCREMENT;

• First, the method in the OP works, but isn't efficient. It may have seemed to run forever, because the dataset was long.
• Use .groupby on the 'method' column, and create a dict of DataFrames with unique 'method' values as the keys, with a dict-comprehension.
  • .groupby returns a groupby object, that contains information about the groups, where g is the unique value in 'method' for each group, and d is the DataFrame for that group.
• The value of each key in df_dict, will be a DataFrame, which can be accessed in the standard way, df_dict['key'].
• The original question wanted a list of DataFrames, which can be done with a list-comprehension
  • df_list = [d for _, d in df.groupby('method')]

Alternatively

• This is a manual method to create separate DataFrames using pandas: Boolean Indexing
• This is similar to the accepted answer, but .loc is not required.
• This is an acceptable method for creating a couple extra DataFrames.
• The pythonic way to create multiple objects, is by placing them in a container (e.g. dict, list, generator, etc.), as shown above.

df1 = df[df.method == 'Astrometry']
df2 = df[df.method == 'Eclipse Timing Variations']

Checkout the -maxdepth flag of find

find . -maxdepth 1 -type d -exec ls -ld "{}" \;

Here I used 1 as max level depth, -type d means find only directories, which then ls -ld lists contents of, in long format.

select TO_CHAR(TRUNC(SYSDATE)+(to_date( '31-MAY-2012 12:25', 'DD-MON-YYYY HH24:MI')

OK it's not quite what the OP asked, but it's what I wanted to do :-)

you can use that code for Kotlin which you will use calendar class from java into Kotlin

    val day = Calendar.getInstance().get(Calendar.DAY_OF_WEEK)

    fun dayOfWeek() {
    println("What day is it today?")
    val day = Calendar.getInstance().get(Calendar.DAY_OF_WEEK)
    println( when (day) {
      1 -> "Sunday"
      2 -> "Monday"
      3 -> "Tuesday"
      4 -> "Wednesday"
      5 -> "Thursday"
      6 -> "Friday"
      7 -> "Saturday"
      else -> "Time has stopped"
   })
 }

You can take advantage of the HTML prompt to unload mechanism, by specifying no unload handler:

window.onbeforeunload = null;
window.location.replace(URL);

See the notes section of the WindowEventHandlers.onbeforeunload for more information.

From, Programming Recommendations, PEP 8:

Comparisons to singletons like None should always be done with is or is not, never the equality operators.

Also, beware of writing if x when you really mean if x is not None — e.g. when testing whether a variable or argument that defaults to None was set to some other value. The other value might have a type (such as a container) that could be false in a boolean context!

PEP 8 is essential reading for any Python programmer.

You can use the beforeSend callback to set additional parameters (The XMLHTTPRequest object is passed to it as its only parameter).

Just so you know, this type of cross-domain request will not work in a normal site scenario and not with any other browser. I don't even know what security limitations FF 3.5 imposes as well, just so you don't beat your head against the wall for nothing:

$.ajax({
    url: 'http://bar.other',
    data: { whatever:'cool' },
    type: 'GET',
    beforeSend: function(xhr){
       xhr.withCredentials = true;
    }
});

One more thing to beware of, is that jQuery is setup to normalize browser differences. You may find that further limitations are imposed by the jQuery library that prohibit this type of functionality.

Edit: replying to self 6 years later

The await keyword is the best way to get a response from an HTTP request, avoiding callbacks and .then()

You'll also need to use an HTTP client that returns Promises. http.get() still returns a Request object, so that won't work.

• fetch is a low level client, that is both available from npm and will be in future versions of node
• superagent is a mature HTTP clients that features more reasonable defaults including simpler query string encoding, properly using mime types, JSON by default, and other common HTTP client features.
• axois is also quite popular and has similar advantages to superagent

await will wait until the Promise has a value - in this case, an HTTP response!

const superagent = require('superagent');

(async function(){
  const response = await superagent.get('https://www.google.com')
  console.log(response.text)
})();

Using await, control simply passes onto the next line once the promise returned by superagent.get() has a value.

var top = $('html').offset().top;

should do it.

edit: this is the negative of $(document).scrollTop()

If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc... you can do this

Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);

And correspondingly, read back to file:

Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);

Following Haskell code calculate the combination number and combinations at the same time, and thanks to Haskell's laziness, you can get one part of them without calculating the other.

import Data.Semigroup
import Data.Monoid

data Comb = MkComb {count :: Int, combinations :: [[Int]]} deriving (Show, Eq, Ord)

instance Semigroup Comb where
    (MkComb c1 cs1) <> (MkComb c2 cs2) = MkComb (c1 + c2) (cs1 ++ cs2)

instance Monoid Comb where
    mempty = MkComb 0 []

addElem :: Comb -> Int -> Comb
addElem (MkComb c cs) x = MkComb c (map (x :) cs)

comb :: Int -> Int -> Comb
comb n k | n < 0 || k < 0 = error "error in `comb n k`, n and k should be natural number"
comb n k | k == 0 || k == n = MkComb 1 [(take k [k-1,k-2..0])]
comb n k | n < k = mempty
comb n k = comb (n-1) k <> (comb (n-1) (k-1) `addElem` (n-1))

It works like:

*Main> comb 0 1
MkComb {count = 0, combinations = []}

*Main> comb 0 0
MkComb {count = 1, combinations = [[]]}

*Main> comb 1 1
MkComb {count = 1, combinations = [[0]]}

*Main> comb 4 2
MkComb {count = 6, combinations = [[1,0],[2,0],[2,1],[3,0],[3,1],[3,2]]}

*Main> count (comb 10 5)
252

Python dictionary is a built-in type that supports key-value pairs.

streetno = {"1": "Sachin Tendulkar", "2": "Dravid", "3": "Sehwag", "4": "Laxman", "5": "Kohli"}

as well as using the dict keyword:

streetno = dict({"1": "Sachin Tendulkar", "2": "Dravid"}) 

or:

streetno = {}
streetno["1"] = "Sachin Tendulkar" 

You can install the JVisualVM plugin from here: https://plugins.jetbrains.com/plugin/3749?pr=

This will allow you to analyse the dump within the plugin.

A check of ibliblio and java.net repositories reveal that jmx related jar is not present in either. I think you should manually download jms and install them locally as discussed here.

Microsoft has a tool called JLCA: Java Language Conversion Assistant. I can't tell if it is better though, as I have never compared the two.

Another (and I think better) way to achieve this is to actually intercept the data. limitTo is okay but what if you're limiting to 10 when your array actually contains thousands?

When calling my service I simply did this:

TaskService.getTasks(function(data){
    $scope.tasks = data.slice(0,10);
});

This limits what is sent to the view, so should be much better for performance than doing this on the front-end.

just write in your css file like bellow

background:url("images/logo.jpg")

np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array).

>>> a = np.array([[0, 1, 6],
                  [2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])

The default behaviour of np.maximum is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:

>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])

But np.maximum is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):

>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])

This is not possible with np.max.

You can make np.maximum imitate np.max to a certain extent when using np.maximum.reduce:

>>> np.maximum.reduce(d)
9
>>> np.max(d)
9

Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max() actually calls np.maximum.reduce to do the computation.

You have to export it from your NgModule:

@NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule],
  providers: []
})
export class TaskModule{}

You can also do it..

editText.setOnKeyListener(new OnKeyListener() {

            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event)
            {
                if (event.getAction() == KeyEvent.ACTION_DOWN
                        && event.getKeyCode() ==       KeyEvent.KEYCODE_ENTER) 
                {
                    Log.i("event", "captured");

                    return false;
                } 

            return false;
        }
    });

function trimArray(&$value) 
{ 
    $value = trim($value); 
}
$pmcArray = array('php ','mysql ', ' code ');
array_walk($pmcArray, 'trimArray');

by using array_walk function, we can remove space from array elements and elements return the result in same array.

FAQ: ICON / SPLASH SCREEN (Cordova 5.x / 2015)

I present my answer as a general FAQ that may help you to solve many problems I've encountered while dealing with icons/splash screens. You may find out like me that the documentation is not always very clear nor up to date. This will probably go to StackOverflow documentation when available.

First: answering the question

How can I add custom app icons for iOS and Android with phonegap?

In your version of Cordova the icon tag is useless. It is not even documented in Cordova 3.0.0. You should use the documentation version that fits the cli you are using and not the latest one!

The icon tag does not work for Android at all before the version 3.5.0 according to what I can see in the different versions of the documentation. In 3.4.0 they still advice to manually copy the files

In newer versions: your config.xml looks better for newer Cordova versions. However there are still many things you may want to know. If you decide to upgrade here are some useful things to modify:

• You don't need the gap: namespace
• You need <preference name="SplashScreen" value="screen" /> for Android

Here are more details of the questions you might ask yourself when trying to deal with icons and splash screen:

Can I use an old version of Cordova / Phonegap

No, the icon/splashscreen feature was not in former versions of Cordova so you must use a recent version. In former versions, only Phonegap Build did handle the icons/splash screen so building locally and handling icons was only possible with a hook. I don't know the minimum version to use this feature but with 5.1.1 it works fine in both Cordova/Phonegap cli. With Cordova 3.5 it didn't work for me.

Edit: for Android you must use at least 3.5.0

How can I debug the build process about icons?

The cli use a CP command. If you provide an invalid icon path, it will show a cp error:

sebastien@sebastien-xps:cordova (dev *+$%)$ cordova run android --device
cp: no such file or directory: /home/sebastien/Desktop/Stample-react/cordova/res/www/stample_splash.png

Edit: you have use cordova build <platform> --verbose to get logs of cp command usage to see where your icons gets copied

The icons should go in a folder according to the config. For me it goes in many subfolders in : platforms/android/build/intermediates/res/armv7/debug/drawable-hdpi-v4/icon.png

Then you can find the APK, and open it as a zip archive to check the icons are present. They must be in a res/drawable* folder because it's a special folder for Android.

Where should I put the icons/splash screens in my project?

In many examples you will find the icons/splash screens are declared inside a res folder. This res is a special Android folder in the output APK, but it does not mean you have to use a res folder in your project.

You can put your icon anywhere, but the path you use must be relative to the root of the project, and not www so take care! This is documented, but not clearly because all the examples are using res and you don't know where this folder is :(

I mean if you put the icon in www/icon.png you absolutly must include www in your path.

Edit Mars 2016: after upgrading my versions, now it seems that icons are relative to www folder but documentation has not been changed (issue)

Does <icon src="icon.png"/> work?

No it does not!.

On Android, it seems it used to work before (when the density attribute was not supported yet?) but not anymore. See this Cordova issue

On iOS, it seems using this global declaration may override more specific declarations so take care and build with --verbose to ensure everything works as expected.

Can I use the same icon/splash screen file for all the densities.

Yes you can. You can even use the same file for both the icon, and splash screen (just to test!). I have used a "big" icon file of 65kb without any problem.

What's the difference when using the platform tag vs the platform attribute

<icon src="icon.png" platform="android" density="ldpi" />

is the same as

<platform name="android">
    <icon src="www/stample_icon.png" density="ldpi" />
</platform>

Should I use the gap: namespace if using Phonegap?

In my experience new versions of Phonegap or Cordova are both able to understand icon declarations without using any gap: xml namespace.

However I'm still waiting for a valid answer here: cordova/phonegap plugin add VS config.xml

As far as I understand, some features with the gap: namespace may be available earlier in PhonegapBuild, then in Phonegap and then being ported to Cordova (?)

Is <preference name="SplashScreen" value="screen" /> required?

At least for Android yes it is. I opened an issue with additional explainations.

Does icon declaration order matters?

Yes it does! It may not have any impact on Android but it has on iOS according to my tests. This is unexpected and undocumented behavior so I opened another issue.

Do I need cordova-plugin-splashscreen?

Yes this is absolutly required if you want the splash screen to work. The documentation is not clear (issue) and let us think that the plugin is required only to offer a splash screen javascript API.

How can I resize the images for all width/height/densities fastly

There are tools to help you do that. The best one for me is http://makeappicon.com/ but it requires to provide an email address.

Other possible solutions are:

• AndroidAssetStudio
• https://gist.github.com/LinusU/7515016
• cordova-icon

Can you give me an example config?

Yes. Here's my real config.xml

A good source of examples are starter kits. Like phonegap-start or Ionic starter

Had the same issue with another number, this worked for me:

1. Click the error message at top "Gradle project sync failed" where the text says ´Open message view´

2. In the "Message Gradle Sync" window on the bottom left corner, click the provided solution "Install missing ... "

3. Repeat 1 and 2 if necessary

23:08 Gradle sync failed: Failed to find target with hash string 'android-26' in: C:\Users\vik\AppData\Local\Android\Sdk

Android SDK providing a solution in the bottom left corner

Basically, there are two ways to set / update data attribute value, depends on your need. The difference is just, where the data saved,

If you use .data() it will be saved in local variable called data_user, and its not visible upon element inspection, If you use .attr() it will be publicly visible.

Much clearer explanation on this comment

you can use this approach, pure HTML and CSS no JS needed :)

Just had to delete all inputs within a div & using the colon in front of the input when targeting gets most everything.

$('#divId').find(':input').val('');

When to do what is a very simple thing if you have the concept clear in your mind.

Abstract classes can be Derived whereas Interfaces can be Implemented. There is some difference between the two. When you derive an Abstract class, the relationship between the derived class and the base class is 'is a' relationship. e.g., a Dog is an Animal, a Sheep is an Animal which means that a Derived class is inheriting some properties from the base class.

Whereas for implementation of interfaces, the relationship is "can be". e.g., a Dog can be a spy dog. A dog can be a circus dog. A dog can be a race dog. Which means that you implement certain methods to acquire something.

I hope I am clear.

Solved my issue in Ubuntu 14.04 OS with python 2.7.6, by adding below two lines into ~/.bash_profile (or ~/.bashrc in unix) files.

source "/usr/local/bin/virtualenvwrapper.sh"

export WORKON_HOME="/opt/virtual_env/"

And then executing both these lines onto the terminal.

Try this:

sed -i 's/\s*$//' youfile.txt

I've been in this (Twitter) industry for a long time and witnessed lots of changes in Twitter API and documentation. I would like to clarify one thing to you. There is no way to surpass 3200 tweets limit. Twitter doesn't provide this data even in its new premium API.

The only way someone can surpass this limit is by saving the tweets of an individual Twitter user.

There are tools available which claim to have a wide database and provide more than 3200 tweets. Few of them are followersanalysis.com, keyhole.co which I know of.

You should not use ftp. Like telnet it is not using secure protocols, and passwords are transmitted in clear text. This makes it very easy for third parties to capture your username and password.

To copy remote directories remotely, these options are better:

• rsync is the best-suited tool if you can login via ssh, because it copies only the differences, and can easily restart in the middle in case the connection breaks.

• ssh -r is the second-best option to recursively copy directory structures.

See:

• rsync man page

• ssh man page

I had the following error while running the cell.

This may be due to not having ffmpeg in your system. Try the following command in your terminal.

sudo apt install ffmpeg

This works for me. I hope it will work out for you too.

For my case, the culprit was the semicolon and double quotes in the password for prod DB. Our IT team use some tool to generate passwords, so it generated one with the semicolon and double quotes Connectionstring looks like

<add key="BusDatabaseConnectionString" value="Data Source=myserver;Initial Catalog=testdb;User Id=Listener;Password=BlaBla"';[]qrk/>

Got the password changed and it worked.

I think you can try this gcc -I/usr/include/mysql *.c -L/usr/lib/mysql -lmysqlclient -o *

Hi First write the Activity class. The following class have a Name of category and small add button. When you press on add (+) button it adds the new row which contains an EditText and an ImageButton which performs the delete of the row.

3. Once you finished your view will as shown below

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

In my case the flask version was only visible under so I had to go to C:\Users\\AppData\Local\flask\venv\Scripts>pip freeze --local

The ffead-cpp provides multiple utility classes for various tasks, one such class is the Date class which provides a lot of features right from Date operations to date arithmetic, there's also a Timer class provided for timing operations. You can have a look at the same.

<button type="button" onclick="loadXMLDoc()"> GET CONTENT</button>

 <script>
        function loadXMLDoc() {
            var xmlhttp = new XMLHttpRequest();
            var url = "<Enter URL>";``
            xmlhttp.onload = function () {
                if (xmlhttp.readyState == 4 && xmlhttp.status == "200") {
                    document.getElementById("demo").innerHTML = this.responseText;
                }
            }
            xmlhttp.open("GET", url, true);
            xmlhttp.send();
        }
    </script>

This is the result from

library(scales)
show_col(hue_pal()(4))

show_col(hue_pal()(3))

I think you've answered your own question: try not to go beyond the 70 Mb limit, however it really depends on many things: what iOS version you're using (not SDK), how many applications running in background, what exact memory you're using etc.

Just avoid the instant memory splashes (e.g. you're using 40 Mb of RAM, and then allocating 80 Mb's more for some short computation). In this case iOS would kill your application immediately.

You should also consider lazy loading of assets (load them only when you really need and not beforehand).

There are many ways to scroll up and down in Selenium Webdriver I always use Java Script to do the same.

Below is the code which always works for me if I want to scroll up or down

 // This  will scroll page 400 pixel vertical
  ((JavascriptExecutor)driver).executeScript("scroll(0,400)");

You can get full code from here Scroll Page in Selenium

If you want to scroll for a element then below piece of code will work for you.

je.executeScript("arguments[0].scrollIntoView(true);",element);

Source code can be:

import urllib
sock = urllib.urlopen("http://diveintopython.org/")
htmlSource = sock.read()                            
sock.close()                                        
print htmlSource  

In this example ordering adds no information - the COUNT of a set is the same whatever order it is in!

If you were selecting something that did depend on order, you would need to do one of the things the error message tells you - use TOP or FOR XML

$_SERVER['REMOTE_ADDR'] may not actually contain real client IP addresses, as it will give you a proxy address for clients connected through a proxy, for example. That may well be what you really want, though, depending what your doing with the IPs. Someone's private RFC1918 address may not do you any good if you're say, trying to see where your traffic is originating from, or remembering what IP the user last connected from, where the public IP of the proxy or NAT gateway might be the more appropriate to store.

There are several HTTP headers like X-Forwarded-For which may or may not be set by various proxies. The problem is that those are merely HTTP headers which can be set by anyone. There's no guarantee about their content. $_SERVER['REMOTE_ADDR'] is the actual physical IP address that the web server received the connection from and that the response will be sent to. Anything else is just arbitrary and voluntary information. There's only one scenario in which you can trust this information: you are controlling the proxy that sets this header. Meaning only if you know 100% where and how the header was set should you heed it for anything of importance.

Having said that, here's some sample code:

if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $ip = $_SERVER['REMOTE_ADDR'];
}

Editor's note: Using the above code has security implications. The client can set all HTTP header information (ie. $_SERVER['HTTP_...) to any arbitrary value it wants. As such it's far more reliable to use $_SERVER['REMOTE_ADDR'], as this cannot be set by the user.

FWIW, here is a sort method for showing which processes are using the most virt memory.

memstat | sort -k 1 -t':' -g -r | less

Sort options are set to first column, using : as column seperator, numeric sort and sort in reverse.

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

To check the existence of a local variable:

if 'myVar' in locals():
  # myVar exists.

To check the existence of a global variable:

if 'myVar' in globals():
  # myVar exists.

To check if an object has an attribute:

if hasattr(obj, 'attr_name'):
  # obj.attr_name exists.

Try this one:

private String toDate() {
    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

    // Create a calendar object with today date. Calendar is in java.util pakage.
    Calendar calendar = Calendar.getInstance();

    // Move calendar to yesterday
    calendar.add(Calendar.DATE, -1);

    // Get current date of calendar which point to the yesterday now
    Date yesterday = calendar.getTime();

    return dateFormat.format(yesterday).toString();
}

My full example is here, but I will provide a summary below.

Layout

Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).

Make the swift file the xib file's owner.

Code

Add the following code to the .swift file and hook up the outlets and actions from the .xib file.

import UIKit
class ResuableCustomView: UIView {

    let nibName = "ReusableCustomView"
    var contentView: UIView?

    @IBOutlet weak var label: UILabel!
    @IBAction func buttonTap(_ sender: UIButton) {
        label.text = "Hi"
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        guard let view = loadViewFromNib() else { return }
        view.frame = self.bounds
        self.addSubview(view)
        contentView = view
    }

    func loadViewFromNib() -> UIView? {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: nibName, bundle: bundle)
        return nib.instantiate(withOwner: self, options: nil).first as? UIView
    }
}

Use it

Use your custom view anywhere in your storyboard. Just add a UIView and set the class name to your custom class name.

For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.

1. Create a custom UIView class in a .swift file to control your xib. i.e. MyCustomClass.swift
2. Create a .xib file and style it as you want. i.e. MyCustomClass.xib
3. Set the File's Owner of the .xib file to be your custom class (MyCustomClass)
4. GOTCHA: leave the class value (under the identity Inspector) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.
5. Hook up your outlets as you normally would using the Assistant Editor.
   • NOTE: If you look at the Connections Inspector you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass), but rather reference File's Owner. Since File's Owner is specified to be your custom class, the outlets will hook up and work propery.
6. Make sure your custom class has @IBDesignable before the class statement.
7. Make your custom class conform to the NibLoadable protocol referenced below.
   • NOTE: If your custom class .swift file name is different from your .xib file name, then set the nibName property to be the name of your .xib file.
8. Implement required init?(coder aDecoder: NSCoder) and override init(frame: CGRect) to call setupFromNib() like the example below.
9. Add a UIView to your desired storyboard and set the class to be your custom class name (i.e. MyCustomClass).
10. Watch IBDesignable in action as it draws your .xib in the storyboard with all of it's awe and wonder.

Here is the protocol you will want to reference:

public protocol NibLoadable {
    static var nibName: String { get }
}

public extension NibLoadable where Self: UIView {

    public static var nibName: String {
        return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
    }

    public static var nib: UINib {
        let bundle = Bundle(for: Self.self)
        return UINib(nibName: Self.nibName, bundle: bundle)
    }

    func setupFromNib() {
        guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
        addSubview(view)
        view.translatesAutoresizingMaskIntoConstraints = false
        view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
        view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
        view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
        view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
    }
}

And here is an example of MyCustomClass that implements the protocol (with the .xib file being named MyCustomClass.xib):

@IBDesignable
class MyCustomClass: UIView, NibLoadable {

    @IBOutlet weak var myLabel: UILabel!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupFromNib()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupFromNib()
    }

}

NOTE: If you miss the Gotcha and set the class value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder) method which then calls Self.nib.instantiate and calls the init again.

How floats work

When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.

float vs display:inline

Before the invention of display:inline-block, websites use float to set elements beside each other. float is preferred over display:inline since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.

Float problems

The main problem is that we're using float against its intended purpose.

Another is that while float allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>, the <div> will not impart 100px in height to the container.

Unlike position:absolute, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.

Clearfix to the rescue

What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear.

Examples

Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.

What you have

Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:

• The first clearfix you have appends an invisible pseudo-element, which is styled clear:both, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.

• The second one appends the style display:inline-block which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.

• This was the reapplication of display:block due to IE-MAC rule above. This rule was "hidden" from IE-MAC.

All in all, these 3 rules keep the .clearfix working cross-browser, with old browsers in mind.

I don't think that can be done RELIABLY with built in methods on the native Date object. The toLocaleString method gets close, but if I am remembering correctly, it won't work correctly in IE < 10. If you are able to use a library for this task, MomentJS is a really amazing library; and it makes working with dates and times easy. Otherwise, I think you will have to write a basic function to give you the format that you are after.

function formatDate(date) {
    var year = date.getFullYear(),
        month = date.getMonth() + 1, // months are zero indexed
        day = date.getDate(),
        hour = date.getHours(),
        minute = date.getMinutes(),
        second = date.getSeconds(),
        hourFormatted = hour % 12 || 12, // hour returned in 24 hour format
        minuteFormatted = minute < 10 ? "0" + minute : minute,
        morning = hour < 12 ? "am" : "pm";

    return month + "/" + day + "/" + year + " " + hourFormatted + ":" +
            minuteFormatted + morning;
}

I noticed few things:

Ctrl+/ toggles Folding-enabled or -disabled.

It is Ctrl+* that expands. Ctrl+Shift+* collapses just like Ctrl+Shift+/

It is funny that a lot of answers here from not knowing the languages. This is especially true for C/C++ programmers who have opened and old FORTRAN 77 code and discuss the weaknesses.

I suppose that the speed issue is mostly a question between C/C++ and Fortran. In a Huge code, it always depends on the programmer. There are some features of the language that Fortran outperforms and some features which C does. So, in 2011, no one can really say which one is faster.

About the language itself, Fortran nowadays supports Full OOP features and it is fully backward compatible. I have used the Fortran 2003 thoroughly and I would say it was just delightful to use it. In some aspects, Fortran 2003 is still behind C++ but let's look at the usage. Fortran is mostly used for Numerical Computation, and nobody uses fancy C++ OOP features because of speed reasons. In high performance computing, C++ has almost no place to go(have a look at the MPI standard and you'll see that C++ has been deprecated!).

Nowadays, you can simply do mixed language programming with Fortran and C/C++. There are even interfaces for GTK+ in Fortran. There are free compilers (gfortran, g95) and many excellent commercial ones.

Using Redux-saga

As Dan Abramov said, if you want more advanced control over your async code, you might take a look at redux-saga.

This answer is a simple example, if you want better explanations on why redux-saga can be useful for your application, check this other answer.

The general idea is that Redux-saga offers an ES6 generators interpreter that permits you to easily write async code that looks like synchronous code (this is why you'll often find infinite while loops in Redux-saga). Somehow, Redux-saga is building its own language directly inside Javascript. Redux-saga can feel a bit difficult to learn at first, because you need basic understanding of generators, but also understand the language offered by Redux-saga.

I'll try here to describe here the notification system I built on top of redux-saga. This example currently runs in production.

Advanced notification system specification

• You can request a notification to be displayed
• You can request a notification to hide
• A notification should not be displayed more than 4 seconds
• Multiple notifications can be displayed at the same time
• No more than 3 notifications can be displayed at the same time
• If a notification is requested while there are already 3 displayed notifications, then queue/postpone it.

Result

Screenshot of my production app Stample.co

Code

Here I named the notification a toast but this is a naming detail.

function* toastSaga() {

    // Some config constants
    const MaxToasts = 3;
    const ToastDisplayTime = 4000;


    // Local generator state: you can put this state in Redux store
    // if it's really important to you, in my case it's not really
    let pendingToasts = []; // A queue of toasts waiting to be displayed
    let activeToasts = []; // Toasts currently displayed


    // Trigger the display of a toast for 4 seconds
    function* displayToast(toast) {
        if ( activeToasts.length >= MaxToasts ) {
            throw new Error("can't display more than " + MaxToasts + " at the same time");
        }
        activeToasts = [...activeToasts,toast]; // Add to active toasts
        yield put(events.toastDisplayed(toast)); // Display the toast (put means dispatch)
        yield call(delay,ToastDisplayTime); // Wait 4 seconds
        yield put(events.toastHidden(toast)); // Hide the toast
        activeToasts = _.without(activeToasts,toast); // Remove from active toasts
    }

    // Everytime we receive a toast display request, we put that request in the queue
    function* toastRequestsWatcher() {
        while ( true ) {
            // Take means the saga will block until TOAST_DISPLAY_REQUESTED action is dispatched
            const event = yield take(Names.TOAST_DISPLAY_REQUESTED);
            const newToast = event.data.toastData;
            pendingToasts = [...pendingToasts,newToast];
        }
    }


    // We try to read the queued toasts periodically and display a toast if it's a good time to do so...
    function* toastScheduler() {
        while ( true ) {
            const canDisplayToast = activeToasts.length < MaxToasts && pendingToasts.length > 0;
            if ( canDisplayToast ) {
                // We display the first pending toast of the queue
                const [firstToast,...remainingToasts] = pendingToasts;
                pendingToasts = remainingToasts;
                // Fork means we are creating a subprocess that will handle the display of a single toast
                yield fork(displayToast,firstToast);
                // Add little delay so that 2 concurrent toast requests aren't display at the same time
                yield call(delay,300);
            }
            else {
                yield call(delay,50);
            }
        }
    }

    // This toast saga is a composition of 2 smaller "sub-sagas" (we could also have used fork/spawn effects here, the difference is quite subtile: it depends if you want toastSaga to block)
    yield [
        call(toastRequestsWatcher),
        call(toastScheduler)
    ]
}

And the reducer:

const reducer = (state = [],event) => {
    switch (event.name) {
        case Names.TOAST_DISPLAYED:
            return [...state,event.data.toastData];
        case Names.TOAST_HIDDEN:
            return _.without(state,event.data.toastData);
        default:
            return state;
    }
};

Usage

You can simply dispatch TOAST_DISPLAY_REQUESTED events. If you dispatch 4 requests, only 3 notifications will be displayed, and the 4th one will appear a bit later once the 1st notification disappears.

Note that I don't specifically recommend dispatching TOAST_DISPLAY_REQUESTED from JSX. You'd rather add another saga that listens to your already-existing app events, and then dispatch the TOAST_DISPLAY_REQUESTED: your component that triggers the notification, does not have to be tightly coupled to the notification system.

Conclusion

My code is not perfect but runs in production with 0 bugs for months. Redux-saga and generators are a bit hard initially but once you understand them this kind of system is pretty easy to build.

It's even quite easy to implement more complex rules, like:

• when too many notifications are "queued", give less display-time for each notification so that the queue size can decrease faster.
• detect window size changes, and change the maximum number of displayed notifications accordingly (for example, desktop=3, phone portrait = 2, phone landscape = 1)

Honnestly, good luck implementing this kind of stuff properly with thunks.

Note you can do exactly the same kind of thing with redux-observable which is very similar to redux-saga. It's almost the same and is a matter of taste between generators and RxJS.

If you want your dates to conform a particular format or formats then use DateTime.TryParseExact otherwise that is the default behaviour of DateTime.TryParse

DateTime.TryParse

This method tries to ignore unrecognized data, if possible, and fills in missing month, day, and year information with the current date. If s contains only a date and no time, this method assumes the time is 12:00 midnight. If s includes a date component with a two-digit year, it is converted to a year in the current culture's current calendar based on the value of the Calendar.TwoDigitYearMax property. Any leading, inner, or trailing white space character in s is ignored.

If you want to confirm against multiple formats then look at DateTime.TryParseExact Method (String, String[], IFormatProvider, DateTimeStyles, DateTime) overload. Example from the same link:

string[] formats= {"M/d/yyyy h:mm:ss tt", "M/d/yyyy h:mm tt", 
                   "MM/dd/yyyy hh:mm:ss", "M/d/yyyy h:mm:ss", 
                   "M/d/yyyy hh:mm tt", "M/d/yyyy hh tt", 
                   "M/d/yyyy h:mm", "M/d/yyyy h:mm", 
                   "MM/dd/yyyy hh:mm", "M/dd/yyyy hh:mm"};
string[] dateStrings = {"5/1/2009 6:32 PM", "05/01/2009 6:32:05 PM", 
                        "5/1/2009 6:32:00", "05/01/2009 06:32", 
                        "05/01/2009 06:32:00 PM", "05/01/2009 06:32:00"}; 
DateTime dateValue;

foreach (string dateString in dateStrings)
{
   if (DateTime.TryParseExact(dateString, formats, 
                              new CultureInfo("en-US"), 
                              DateTimeStyles.None, 
                              out dateValue))
      Console.WriteLine("Converted '{0}' to {1}.", dateString, dateValue);
   else
      Console.WriteLine("Unable to convert '{0}' to a date.", dateString);
}
// The example displays the following output: 
//       Converted '5/1/2009 6:32 PM' to 5/1/2009 6:32:00 PM. 
//       Converted '05/01/2009 6:32:05 PM' to 5/1/2009 6:32:05 PM. 
//       Converted '5/1/2009 6:32:00' to 5/1/2009 6:32:00 AM. 
//       Converted '05/01/2009 06:32' to 5/1/2009 6:32:00 AM. 
//       Converted '05/01/2009 06:32:00 PM' to 5/1/2009 6:32:00 PM. 
//       Converted '05/01/2009 06:32:00' to 5/1/2009 6:32:00 AM.

try this

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

You can also use the FileFilter interface to filter out what you want. It is best used when you create an anonymous class that implements it:

import java.io.File;
import java.io.FileFilter;

public class ListFiles {
    public File[] findDirectories(File root) { 
        return root.listFiles(new FileFilter() {
            public boolean accept(File f) {
                return f.isDirectory();
            }});
    }

    public File[] findFiles(File root) {
        return root.listFiles(new FileFilter() {
            public boolean accept(File f) {
                return f.isFile();
            }});
    }
}

I found this method: Matcher.replaceAll(String replacement); In java.util.regex.Matcher.java you can see more:

 /**
 * Replaces every subsequence of the input sequence that matches the
 * pattern with the given replacement string.
 *
 * <p> This method first resets this matcher.  It then scans the input
 * sequence looking for matches of the pattern.  Characters that are not
 * part of any match are appended directly to the result string; each match
 * is replaced in the result by the replacement string.  The replacement
 * string may contain references to captured subsequences as in the {@link
 * #appendReplacement appendReplacement} method.
 *
 * <p> Note that backslashes (<tt>\</tt>) and dollar signs (<tt>$</tt>) in
 * the replacement string may cause the results to be different than if it
 * were being treated as a literal replacement string. Dollar signs may be

 *
 * <p> Given the regular expression <tt>a*b</tt>, the input

 */
public String replaceAll(String replacement) {
    reset();
    StringBuffer buffer = new StringBuffer(input.length());
    while (find()) {
        appendReplacement(buffer, replacement);
    }
    return appendTail(buffer).toString();
}

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance application

H264 is now enshrined in MPEG4 as part 10 also known as AVC

Refer to: http://www.velleman.eu/downloads/3/h264_vs_mpeg4_en.pdf

Hope this helps.

Here is a userAgent solution that is more efficent than match...

function _isMobile(){
    // if we want a more complete list use this: http://detectmobilebrowsers.com/
    // str.test() is more efficent than str.match()
    // remember str.test is case sensitive
    var isMobile = (/iphone|ipod|android|ie|blackberry|fennec/).test
         (navigator.userAgent.toLowerCase());
    return isMobile;
}

Add this to script object from your project's package.json file

    "start":"nodemon index.js"

It should be like this

    "scripts": {
        "start":"nodemon index.js"
    }

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

Very easy way to separate value and its fractional part value.

double  d = 3.5;
int i = (int)d;
string s = d.ToString();
s = s.Replace(i + ".", "");

s is fractional part = 5 and
i is value as integer = 3

You have multiple options. Two options are the following.

numpy.sum(boolarr)
numpy.count_nonzero(boolarr)

Here's an example:

>>> import numpy as np
>>> boolarr = np.array([[0, 0, 1], [1, 0, 1], [1, 0, 1]], dtype=np.bool)
>>> boolarr
array([[False, False,  True],
       [ True, False,  True],
       [ True, False,  True]], dtype=bool)

>>> np.sum(boolarr)
5

Of course, that is a bool-specific answer. More generally, you can use numpy.count_nonzero.

>>> np.count_nonzero(boolarr)
5

Chances are that you've not included the header file that declares system().

In order to be able to compile C++ code that uses functions which you don't (manually) declare yourself, you have to pull in the declarations. These declarations are normally stored in so-called header files that you pull into the current translation unit using the #include preprocessor directive. As the code does not #include the header file in which system() is declared, the compilation fails.

To fix this issue, find out which header file provides you with the declaration of system() and include that. As mentioned in several other answers, you most likely want to add #include <cstdlib>

Thanks Sanoj, that worked for me.
However iOS does not support "onbeforeunload" on iPhone. Workaround for me was to set localStorage with js:

<button onclick="myFunction()">Click me</button>

<script>
document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });
function myFunction() {
  localStorage.setItem('scrollpos', window.scrollY);
  location.reload(); 
}
</script>

Bash sets the shell variable OSTYPE. From man bash:

Automatically set to a string that describes the operating system on which bash is executing.

This has a tiny advantage over uname in that it doesn't require launching a new process, so will be quicker to execute.

However, I'm unable to find an authoritative list of expected values. For me on Ubuntu 14.04 it is set to 'linux-gnu'. I've scraped the web for some other values. Hence:

case "$OSTYPE" in
  linux*)   echo "Linux / WSL" ;;
  darwin*)  echo "Mac OS" ;; 
  win*)     echo "Windows" ;;
  msys*)    echo "MSYS / MinGW / Git Bash" ;;
  cygwin*)  echo "Cygwin" ;;
  bsd*)     echo "BSD" ;;
  solaris*) echo "Solaris" ;;
  *)        echo "unknown: $OSTYPE" ;;
esac

The asterisks are important in some instances - for example OSX appends an OS version number after the 'darwin'. The 'win' value is actually 'win32', I'm told - maybe there is a 'win64'?

Perhaps we could work together to populate a table of verified values here:

• Linux Ubuntu (incl. WSL): linux-gnu
• Cygwin 64-bit: cygwin
• Msys/MINGW (Git Bash for Windows): msys

(Please append your value if it differs from existing entries)

I've answered my own question. Call apply_filter and there you go.

<?php 
$id=47; 
$post = get_post($id); 
$content = apply_filters('the_content', $post->post_content); 
echo $content;

One of the main motivations for using an abstract class is to enable polymorphism within your application -- i.e: you can substitute a different version at runtime. In fact, this is very much the same thing as using an interface except the abstract class provides some common plumbing, often referred to as a Template pattern.

From a unit testing perspective, there are two things to consider:

1. Interaction of your abstract class with it related classes. Using a mock testing framework is ideal for this scenario as it shows that your abstract class plays well with others.

2. Functionality of derived classes. If you have custom logic that you've written for your derived classes, you should test those classes in isolation.

edit: RhinoMocks is an awesome mock testing framework that can generate mock objects at runtime by dynamically deriving from your class. This approach can save you countless hours of hand-coding derived classes.

This is an answer targeting primarily developers using Windows, as the path syntax of the diff tool differs from other platforms.

I use Kdiff3 as the git mergetool, but to set up the git difftool as Meld, I first installed the latest version of Meld from Meldmerge.org then added the following to my global .gitconfig using:

git config --global -e

Note, if you rather want Sublime Text 3 instead of the default Vim as core ditor, you can add this to the .gitconfig file:

[core]
editor = 'c:/Program Files/Sublime Text 3/sublime_text.exe'

Then you add inn Meld as the difftool

[diff]
tool = meld
guitool = meld 

[difftool "meld"]
cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" \"$LOCAL\" \"$REMOTE\" --label \"DIFF 
(ORIGINAL MY)\"
prompt = false
path = C:\\Program Files (x86)\\Meld\\Meld.exe

Note the leading slash in the cmd above, on Windows it is necessary.

It is also possible to set up an alias to show the current git diff with a --dir-diff option. This will list the changed files inside Meld, which is handy when you have altered multiple files (a very common scenario indeed).

The alias looks like this inside the .gitconfig file, beneath [alias] section:

showchanges = difftool --dir-diff

To show the changes I have made to the code I then just enter the following command:

git showchanges

The following image shows how this --dir-diff option can show a listing of changed files (example):

Then it is possible to click on each file and show the changes inside Meld.

pam-face-authentication a PAM Module for Face Authentication: but it would require some work to get what you want. A quick test showed, that the recognition rate are not as good as those of VeriLook from NeuroTechnology.

Malic is another open source face recognition software, which uses Gabor Wavelet descriptors. But the last update to the source is 3 years old.

From the website: "Malic is an opensource face recognition software which uses gabor wavelet. It is realtime face recognition system that based on Malib and CSU Face Identification Evaluation System (csuFaceIdEval).Uses Malib library for realtime image processing and some of csuFaceIdEval for face recognition."

SPServices is a jQuery library which abstracts SharePoint's Web Services and makes them easier to use

It is certified for SharePoint 2007

The list of supported operations for Lists.asmx could be found here

Example

In this example, we're grabbing all of the items in the Announcements list and displaying the Titles in a bulleted list in the tasksUL div:

<script type="text/javascript" src="filelink/jquery-1.6.1.min.js"></script>
<script type="text/javascript" src="filelink/jquery.SPServices-0.6.2.min.js"></script>
<script language="javascript" type="text/javascript">

$(document).ready(function() {
  $().SPServices({
    operation: "GetListItems",
    async: false,
    listName: "Announcements",
    CAMLViewFields: "<ViewFields><FieldRef Name='Title' /></ViewFields>",
    completefunc: function (xData, Status) {
      $(xData.responseXML).SPFilterNode("z:row").each(function() {
        var liHtml = "<li>" + $(this).attr("ows_Title") + "</li>";
        $("#tasksUL").append(liHtml);
      });
    }
  });
});
</script>
<ul id="tasksUL"/>

I just added a custom class to the ul section named target-active

<ul class="nav navbar-nav target-active">
    <li><a href="/">HOME</a></li>
    <li><a href="find-truck">FIND A TRUCK</a></li>
    <li><a href="our-service">OUR SERVICES</a></li>
    <li><a href="about-us">ABOUT US</a></li>
</ul>

If each li tags click get a new page from different place or same place, no need to add jquery removeClass function.

Add simple one line jquery code to each page to get your desired result

1st link page

$(function(){
    $(".target-active").find("[href='/']").parent().addClass("active");
});

2nd link page

$(function(){
    $(".target-active").find("[href=find-truck]").parent().addClass("active");
});

3rd link page

$(function(){
    $(".target-active").find("[href=our-service]").parent().addClass("active");
});

4th link page

$(function(){
    $(".target-active").find("[href=about-us]").parent().addClass("active");
});

If you can depend on the Google libraries being there for you target market, then you may want to piggy back on GTalk functionality (registering a resource on the existing username - the intercepting it the messages as they come in with a BroadcastReceiver).

If not, and I expect you can't, then you're into bundling your own versions of XMPP. This is a pain, but may be made easier if XMPP is bundled separately as a standalone library.

You may also consider PubSubHubub, but I have no idea the network usage of it. I believe it is built atop of XMPP.

You can access this by

Right click on instance (IE SQLServer2008)
Select "Properties"
Select "Security" option
Change "Server authentication" to "SQL Server and Windows Authentication mode"
Restart the SQLServer service
    Right click on instance
    Click "Restart"

Just for anyone else reading this: This worked for me on 2012 SQL Server too. Thanks

There is no good way to do that, but you should use portable solution, so avoid system() calls, in your case you could use cin.get() or getch() as you mentioned in your question, also there is one advice. Make all pauses controlled by one (or very few) preprocessor definitions.

For example:

Somewhere in global file:

#define USE_PAUSES
#ifndef _DEBUG    //I asume you have _DEBUG definition for debug and don't have it for release build
#undef USE_PAUSES
#endif

Somewhere in code

#ifdef USE_PAUSES
cin.get();
#endif

This is not universal advice, but you should protect yourself from putting pauses in release builds and these should have easy control, my mentioned global file may not be so global, because changes in that may cause really long compilation.

Make it like this:

$scope.users.data.length;

After some trial and error and observing the results (in other words, I hacked it), I got it to work.

Quotes ARE required to use a path name with spaces. The trick is there MUST be a space after the path names before the closing quote...like this...

robocopy "C:\Source Path " "C:\Destination Path " /option1 /option2...

This almost seems like a bug and certainly not very intuitive.

We've been working on a similar issue at work today, trying to figure out how to make a dropdown div disappear when it is clicked off of. Ours is slightly different than the initial poster's question because we didn't want to click away from a different component or directive, but merely outside of the particular div.

We ended up solving it by using the (window:mouseup) event handler.

Steps:
1.) We gave the entire dropdown menu div a unique class name.

2.) On the inner dropdown menu itself (the only portion that we wanted clicks to NOT close the menu), we added a (window:mouseup) event handler and passed in the $event.

NOTE: It could not be done with a typical "click" handler because this conflicted with the parent click handler.

3.) In our controller, we created the method that we wanted to be called on the click out event, and we use the event.closest (docs here) to find out if the clicked spot is within our targeted-class div.

 autoCloseForDropdownCars(event) {_x000D_
        var target = event.target;_x000D_
        if (!target.closest(".DropdownCars")) { _x000D_
            // do whatever you want here_x000D_
        }_x000D_
    }

 <div class="DropdownCars">_x000D_
   <span (click)="toggleDropdown(dropdownTypes.Cars)" class="searchBarPlaceholder">Cars</span>_x000D_
   <div class="criteriaDropdown" (window:mouseup)="autoCloseForDropdownCars($event)" *ngIf="isDropdownShown(dropdownTypes.Cars)">_x000D_
   </div>_x000D_
</div>

This is what I came up with

from calendar  import monthrange

def same_day_months_after(start_date, months=1):
    target_year = start_date.year + ((start_date.month + months) / 12)
    target_month = (start_date.month + months) % 12
    num_days_target_month = monthrange(target_year, target_month)[1]
    return start_date.replace(year=target_year, month=target_month, 
        day=min(start_date.day, num_days_target_month))

There is a parse_dates parameter for read_csv which allows you to define the names of the columns you want treated as dates or datetimes:

date_cols = ['col1', 'col2']
pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=date_cols)

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

Regarding number of days in month just use static switch command and check if (year % 4 == 0) in which case February will have 29 days.

Minute, hour, day etc:

var someMillisecondValue = 511111222127;
var date = new Date(someMillisecondValue);
var minute = date.getMinutes();
var hour = date.getHours();
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
alert([minute, hour, day, month, year].join("\n"));

My current solution is to run:

my_string.unpack("C*").pack("U*")

This will at least get rid of the exceptions which was my main problem

Python 3:

import urllib.request

wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)

Python 2:

import urllib
import sys

wp = urllib.urlopen("http://google.com")
for line in wp:
    sys.stdout.write(line)

While I have tested both the Codes in respective versions.

From the javascript I tried from several ways and I could not.

You need an server side solution, for example on c# I did create an controller that call to the http, en deserialize the object, and the result is that when I call from javascript, I'm doing an request from my https://domain to my htpps://domain. Please see my c# code:

[Authorize]
public class CurrencyServicesController : Controller
{
    HttpClient client;
    //GET: CurrencyServices/Consultar?url=valores?moedas=USD&alt=json
    public async Task<dynamic> Consultar(string url)
    {
        client = new HttpClient();
        client.BaseAddress = new Uri("http://api.promasters.net.br/cotacao/v1/");
        client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
        System.Net.Http.HttpResponseMessage response = client.GetAsync(url).Result;

        var FromURL = response.Content.ReadAsStringAsync().Result;

        return JsonConvert.DeserializeObject(FromURL);
    }

And let me show to you my client side (Javascript)

<script async>
$(document).ready(function (data) {

    var TheUrl = '@Url.Action("Consultar", "CurrencyServices")?url=valores';
    $.getJSON(TheUrl)
        .done(function (data) {
            $('#DolarQuotation').html(
                '$ ' + data.valores.USD.valor.toFixed(2) + ','
            );
            $('#EuroQuotation').html(
                '€ ' + data.valores.EUR.valor.toFixed(2) + ','
            );

            $('#ARGPesoQuotation').html(
                'Ar$ ' + data.valores.ARS.valor.toFixed(2) + ''
            );

        });       

});

I wish that this help you! Greetings

var str = "How are you doing today?";

var res = str.split(" ");

Here the variable "res" is kind of array.

You can also take this explicity by declaring it as

var res[]= str.split(" ");

Now you can access the individual words of the array. Suppose you want to access the third element of the array you can use it by indexing array elements.

var FirstElement= res[0];

Now the variable FirstElement contains the value 'How'

If both "document.ready" variants are used they will both fire, in the order of appearance

$(function(){
    alert('shorthand document.ready');
});

//try changing places
$(document).ready(function(){
    alert('document.ready');
});

You try and compare pointers here, not the contents of what is pointed to (ie, your characters).

You must use either memcmp or str{,n}cmp to compare the contents.

You also use this below to expand the memory

export _JAVA_OPTIONS="-Xms512m -Xmx1024m -Xss512m -XX:MaxPermSize=1024m"

Xmx specifies the maximum memory allocation pool for a Java virtual machine (JVM)

Xms specifies the initial memory allocation pool.

Xss setting memory size of thread stack

XX:MaxPermSize: the maximum permanent generation size

puts or p is a good start to do that.

p "asd"       # => "asd"
puts "asd"    # => asd

here is more information about that: http://www.ruby-doc.org/core-1.9.3/ARGF.html

I put together a little category on UITableView based on Anna Karenina's excellent answer.

Like this you'll have a convenient delegate method like you're used to when dealing with regular table views. Check it out:

//  UITableView+LongPress.h

#import <UIKit/UIKit.h>

@protocol UITableViewDelegateLongPress;

@interface UITableView (LongPress) <UIGestureRecognizerDelegate>
@property(nonatomic,assign)   id <UITableViewDelegateLongPress>   delegate;
- (void)addLongPressRecognizer;
@end


@protocol UITableViewDelegateLongPress <UITableViewDelegate>
- (void)tableView:(UITableView *)tableView didRecognizeLongPressOnRowAtIndexPath:(NSIndexPath *)indexPath;
@end



//  UITableView+LongPress.m

#import "UITableView+LongPress.h"

@implementation UITableView (LongPress)
@dynamic delegate;

- (void)addLongPressRecognizer {
    UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc]
                                          initWithTarget:self action:@selector(handleLongPress:)];
    lpgr.minimumPressDuration = 1.2; //seconds
    lpgr.delegate = self;
    [self addGestureRecognizer:lpgr];
}


- (void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self];

    NSIndexPath *indexPath = [self indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    }
    else {
        if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
            // I am not sure why I need to cast here. But it seems to be alright.
            [(id<UITableViewDelegateLongPress>)self.delegate tableView:self didRecognizeLongPressOnRowAtIndexPath:indexPath];
        }
    }
}

If you want to use this in a UITableViewController, you probably need to subclass and conform to the new protocol.

It works great for me, hope it helps others!

const o = {
  name: "Max",
  location: "London"
};

for (const [key, value] of Object.entries(o)) {
  console.log(`${key}: ${value}`);
}

Try online

On the data dictionary side there are a lot of tools you can use to such as Schema Spy

To look at what queries are running look at views sys.v_$sql and sys.v_$sqltext. You will also need access to sys.all_users

One thing to note that queries that use parameters will show up once with entries like

and TABLETYPE=’:b16’

while others that dont will show up multiple times such as:

and TABLETYPE=’MT’

An example of these tables in action is the following SQL to find the top 20 diskread hogs. You could change this by removing the WHERE rownum <= 20 and maybe add ORDER BY module. You often find the module will give you a bog clue as to what software is running the query (eg: "TOAD 9.0.1.8", "JDBC Thin Client", "runcbl@somebox (TNS V1-V3)" etc)

SELECT 
 module, 
 sql_text, 
 username, 
 disk_reads_per_exec, 
 buffer_gets, 
 disk_reads, 
 parse_calls, 
 sorts, 
 executions, 
 rows_processed, 
 hit_ratio, 
 first_load_time, 
 sharable_mem, 
 persistent_mem, 
 runtime_mem, 
 cpu_time, 
 elapsed_time, 
 address, 
 hash_value 
FROM 
  (SELECT
   module, 
   sql_text , 
   u.username , 
   round((s.disk_reads/decode(s.executions,0,1, s.executions)),2)  disk_reads_per_exec, 
   s.disk_reads , 
   s.buffer_gets , 
   s.parse_calls , 
   s.sorts , 
   s.executions , 
   s.rows_processed , 
   100 - round(100 *  s.disk_reads/greatest(s.buffer_gets,1),2) hit_ratio, 
   s.first_load_time , 
   sharable_mem , 
   persistent_mem , 
   runtime_mem, 
   cpu_time, 
   elapsed_time, 
   address, 
   hash_value 
  FROM
   sys.v_$sql s, 
   sys.all_users u 
  WHERE
   s.parsing_user_id=u.user_id 
   and UPPER(u.username) not in ('SYS','SYSTEM') 
  ORDER BY
   4 desc) 
WHERE
 rownum <= 20;

Note that if the query is long .. you will have to query v_$sqltext. This stores the whole query. You will have to look up the ADDRESS and HASH_VALUE and pick up all the pieces. Eg:

SELECT
 *
FROM
 sys.v_$sqltext
WHERE
 address = 'C0000000372B3C28'
 and hash_value = '1272580459'
ORDER BY 
 address, hash_value, command_type, piece
;

I think this is what you are looking for:

df.drop('Region', axis=1).apply(lambda x: x.mean(), axis=1)

To simply redirect a browser using javascript:

window.location.href = "http://example.com/new_url";

To redirect AND submit a form (i.e. login details), requires no javascript:

<form action="/new_url" method="POST">
   <input name="username">
   <input type="password" name="password">
   <button type="submit">Submit</button>
</form>

Another thing to keep in mind is that the string itself might be null.

public static Nullable<T> ToNullable<T>(this string s) where T: struct
{
    Nullable<T> result = new Nullable<T>();
    try
    {
        if (!string.IsNullOrEmpty(s) && s.Trim().Length > 0)
        {
            TypeConverter conv = TypeDescriptor.GetConverter(typeof(T));
            result = (T)conv.ConvertFrom(s);
        }
    }
    catch { } 
    return result;
}

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

Using regular for-loop without external libraries:

Convert int[] to Integer[]:

Integer[] objectArray = new Integer[primitiveArray.length];

for(int ctr = 0; ctr < primitiveArray.length; ctr++) {
    objectArray[ctr] = Integer.valueOf(primitiveArray[ctr]); // returns Integer value
}

Convert Integer[] to int[]:

int[] primitiveArray = new int[objectArray.length];

for(int ctr = 0; ctr < objectArray.length; ctr++) {
    primitiveArray[ctr] = objectArray[ctr].intValue(); // returns int value
}

You can also try the HTTP Debugger, it has the built-in ability to display incoming HTTP requests and does not require any changes to the system configuration.

Start an Android Emulator (make sure that all supported APIs are included when you created the emulator, we needed to have the Google APIs for instance).

Then simply email yourself a link to the .apk file, and download it directly in the emulator, and click the downloaded file to install it.

I hope this code will help someone. It took me 2 days to figure out how to log from device, and then filter it:

public File extractLogToFileAndWeb(){
        //set a file
        Date datum = new Date();
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd", Locale.ITALY);
        String fullName = df.format(datum)+"appLog.log";
        File file = new File (Environment.getExternalStorageDirectory(), fullName);

        //clears a file
        if(file.exists()){
            file.delete();
        }


        //write log to file
        int pid = android.os.Process.myPid();
        try {
            String command = String.format("logcat -d -v threadtime *:*");        
            Process process = Runtime.getRuntime().exec(command);

            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            StringBuilder result = new StringBuilder();
            String currentLine = null;

            while ((currentLine = reader.readLine()) != null) {
                   if (currentLine != null && currentLine.contains(String.valueOf(pid))) {
                       result.append(currentLine);
                       result.append("\n");
                    }
            }

            FileWriter out = new FileWriter(file);
            out.write(result.toString());
            out.close();

            //Runtime.getRuntime().exec("logcat -d -v time -f "+file.getAbsolutePath());
        } catch (IOException e) {
            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();
        }


        //clear the log
        try {
            Runtime.getRuntime().exec("logcat -c");
        } catch (IOException e) {
            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();
        }

        return file;
    }

as pointed by @mehdok

add the permission to the manifest for reading logs

<uses-permission android:name="android.permission.READ_LOGS" />

If you just want to do it once, without adding a shortcut, you can always type

<prefix> 
:
kill-window
<enter>

Try PyPDF2.

There is a good tutorial here: https://automatetheboringstuff.com/chapter13/

I had issue with McAfee on my mac blocking port 8081, had to change it to 8082.

First run your package server:

react-native start --port 8082

Open another terminal, start the android app as usual:

react-native run-android

Once it finishes, now rewrite the tcp port that adb tunnels:

adb reverse tcp:8081 tcp:8082

See the list of adb tcp tunnels:

adb reverse --list

You should now see a heartwarming message:

(reverse) tcp:8081 tcp:8082

Go to your app and reload, done!

PS: Don't change anything in the app Dev settings, if you added "localhost:8082", just remove it, leave it blank.

EDIT: To all the McAfee victims out there, there's easier solution if you have root access, just temporarily kill the McAfee process sitting on port 8081 and no need for port change at all:

sudo launchctl remove com.mcafee.agent.macmn

Please Use map() python function.

Input: In case of list of values

index = [u'CARBO1004' u'CARBO1006' u'CARBO1008' u'CARBO1009' u'CARBO1020']

encoded_string = map(str, index)

Output: ['CARBO1004', 'CARBO1006', 'CARBO1008', 'CARBO1009', 'CARBO1020']

For a Single string input:

index = u'CARBO1004'
# Use Any one of the encoding scheme.
index.encode("utf-8")  # To utf-8 encoding scheme
index.encode('ascii', 'ignore')  # To Ignore Encoding Errors and set to default scheme

Output: 'CARBO1004'

Scripted languages

Scripting languages are interpreted within another program. JavaScript is embedded within a browser and interpreted by that browser.

Examples of scripting languages

1. JavaScript
2. Perl
3. Python

Advantages of Scripting languages:

1. Simple – Scripting languages are easier to write than programming language.

2. Fewer Lines of Code (LOC)

Programmed languages

Programming languages like Java are compiled and not interpreted by another application in the same way.

Examples programming languages

1. C
2. C++ and
3. Java

$('tr').click(function(){
 alert( $('tr').index(this) );
});

For first tr, it alerts 0. If you want to alert 1, you can add 1 to index.

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

Whilst not disagreeing with the complex answers about half-way marks and so on, for the more common (and possibly trivial) use-case:

my $rounded = int($float + 0.5);

UPDATE

If it's possible for your $float to be negative, the following variation will produce the correct result:

my $rounded = int($float + $float/abs($float*2 || 1));

With this calculation -1.4 is rounded to -1, and -1.6 to -2, and zero won't explode.

I also had this problem today. Mine was caused by a cyclic dependency. Project A referenced Project B and vice versa.

Yes:

<input required title="Enter something OR ELSE." /> 

The title attribute will be used to notify the user of a problem.

Installing CocoaPods on OS X 10.11

These instructions were tested on all betas and the final release of El Capitan.

Custom GEM_HOME

This is the solution when you are receiving above error

$ mkdir -p $HOME/Software/ruby
$ export GEM_HOME=$HOME/Software/ruby
$ gem install cocoapods
[...]
1 gem installed
$ export PATH=$PATH:$HOME/Software/ruby/bin
$ pod --version

Put your ScrollViewer in a DockPanel and set the DockPanel MaxHeight property

[...]
<DockPanel MaxHeight="700">
  <ScrollViewer VerticalScrollBarVisibility="Auto">
   <ItemsControl ItemSource ="{Binding ...}">
     [...]
   </ItemsControl>
  </ScrollViewer>
</DockPanel>
[...]

I had the same problem. It's true the password is empty, but even so the error message is shown. The solution is just using "sudo" so

$ sudo mysql

will open the mysql tool

For securing the database, you should use sudo again.

$ sudo mysql_secure_installation

To expand on what Shimi has said, you should only be running your loop from 1 to the square root of n. Then to find the pair, do n / i, and this will cover the whole problem space.

As was also noted, this is a NP, or 'difficult' problem. Exhaustive search, the way you are doing it, is about as good as it gets for guaranteed answers. This fact is used by encryption algorithms and the like to help secure them. If someone were to solve this problem, most if not all of our current 'secure' communication would be rendered insecure.

Python code:

import math

def divisorGenerator(n):
    large_divisors = []
    for i in xrange(1, int(math.sqrt(n) + 1)):
        if n % i == 0:
            yield i
            if i*i != n:
                large_divisors.append(n / i)
    for divisor in reversed(large_divisors):
        yield divisor

print list(divisorGenerator(100))

Which should output a list like:

[1, 2, 4, 5, 10, 20, 25, 50, 100]

You can also add prompt option like this.

<%= f.select(:object_field, ['Item 1', 'Item 2'], {include_blank: "Select something"}, { :class => 'my_style_class' }) %>

To get the latest tag only on the current branch/tag name that prefixes with current branch, I had to execute the following

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags --abbrev=0 $BRANCH^ | grep $BRANCH

Branch master:

git checkout master

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

master-1448

Branch custom:

git checkout 9.4

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

9.4-6

And my final need to increment and get the tag +1 for next tagging.

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags  --abbrev=0 $BRANCH^ | grep $BRANCH | awk -F- '{print $NF}'

The direct way of doing this is to create triggers on tables. Set some conditions or mapping methods. When update or delete occurs, it will insert into 'change' table automatically.

But the biggest part is what if we got lots columns and lots of table. We have to type every column's name of every table. Obviously, It's waste of time.

To handle this more gorgeously, we can create some procedures or functions to retrieve name of columns.

We can also use 3rd-part tool simply to do this. Here, I write a java program Mysql Tracker

Use request.get_data() to get the raw data, regardless of content type. The data is cached and you can subsequently access request.data, request.json, request.form at will.

If you access request.data first, it will call get_data with an argument to parse form data first. If the request has a form content type (multipart/form-data, application/x-www-form-urlencoded, or application/x-url-encoded) then the raw data will be consumed. request.data and request.json will appear empty in this case.

Try this:

   import * as moment from 'moment';

     ngOnInit() {
     this.date = moment().format("YYYY Do MMM");
                }

Thank you all for your help.

This is what I have used in the end:

SELECT *, 
  CASE WHEN [url] NOT LIKE '%[^-A-Za-z0-9/.+$]%' 
    THEN 'Valid' 
    ELSE 'No valid' 
  END [Validate]
FROM 
  *table*
  ORDER BY [Validate]

[excel 2010] separate the date and time into separate columns and select both as X-Axis and data as graph series see http://www.79783.mrsite.com/USERIMAGES/horizontal_axis_date_and_time2.xlsx

The simplest way to display last element in python is

>>> list[-1:] # returns indexed value
    [3]
>>> list[-1]  # returns value
    3

there are many other method to achieve such a goal but these are short and sweet to use.

It appears as though you need to explicitly set a font, and change the line-height and height as needed. Assuming 'Times New Roman' is your browser's default font:

span {_x000D_
  display: inline-block;_x000D_
  font-size: 50px;_x000D_
  background-color: green;_x000D_
  /*new:*/_x000D_
  font-family: 'Times New Roman';_x000D_
  line-height: 34px;_x000D_
  height: 35px;_x000D_
}

<link href='http://fonts.googleapis.com/css?family=Tinos' rel='stylesheet' type='text/css'>_x000D_
<span>_x000D_
    BIG TEXT_x000D_
</span>

Starting with Node.js 11, the url.parse and other methods of the Legacy URL API were deprecated (only in the documentation, at first) in favour of the standardized WHATWG URL API. The new API does not offer parsing the query string into an object. That can be achieved using tthe querystring.parse method:

// Load modules to create an http server, parse a URL and parse a URL query.
const http = require('http');
const { URL } = require('url');
const { parse: parseQuery } = require('querystring');

// Provide the origin for relative URLs sent to Node.js requests.
const serverOrigin = 'http://localhost:8000';

// Configure our HTTP server to respond to all requests with a greeting.
const server = http.createServer((request, response) => {
  // Parse the request URL. Relative URLs require an origin explicitly.
  const url = new URL(request.url, serverOrigin);
  // Parse the URL query. The leading '?' has to be removed before this.
  const query = parseQuery(url.search.substr(1));
  response.writeHead(200, { 'Content-Type': 'text/plain' });
  response.end(`Hello, ${query.name}!\n`);
});

// Listen on port 8000, IP defaults to 127.0.0.1.
server.listen(8000);

// Print a friendly message on the terminal.
console.log(`Server running at ${serverOrigin}/`);

If you run the script above, you can test the server response like this, for example:

curl -q http://localhost:8000/status?name=ryan
Hello, ryan!

I just got another case to display backslash \ with Razor and Java Script.

My @Model.AreaName looks like Name1\Name2\Name3 so when I display it all backslashes are gone and I see Name1Name2Name3

I found solution to fix it:

var areafullName =  JSON.parse("@Html.Raw(HttpUtility.JavaScriptStringEncode(JsonConvert.SerializeObject(Model.AreaName)))");

Don't forget to add @using Newtonsoft.Json on top of chtml page.

The Default Expiration Period for Session is 20 Minutes.

You can update sessionstate and configure the minutes under timeout

<sessionState 
timeout="30">
</sessionState>

With Sequel Pro:

Restarting the app unlocked my tables. It resets the session connection.

NOTE: I was doing this for a site on my local machine.

I'm under the impression that some enterprises (e.g.: JackBe) put encrypted JavaScript code inside *.gif files, rather than JS files, as an additional measure of obfuscation.

No, since the new throw is not in the try block directly.

One best way is by using window.INITIAL_STATE

<script src="/firstfile.js">
    // first.js
    window.__INITIAL_STATE__ = {
      back  : "#fff",
      front : "#888",
      side  : "#369"
    };
</script>
<script src="/secondfile.js">
    //second.js
    console.log(window.__INITIAL_STATE__)
    alert (window.__INITIAL_STATE__);
</script>

Yes you can. You write your code in tinypy (which is restricted Python), then use tinypy to convert it to C++, and finally compile this with XCode into a native iPhone app. Phil Hassey has published a game called Elephants! using this approach. Here are more details,

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing } character. What's the length of result1 versus result2? I'll note that result2 as you've quoted it has 169 characters.

GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t, \n, \r, and space count as whitespace. In particular, note that trailing NUL (\0) characters do not count as whitespace and will cause this error.

If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);

exec is for statement and does not return anything. eval is for expression and returns value of expression.

expression means "something" while statement means "do something".

Try swapping your colon : for a bar |. that should do it

With dplyr you would do:

library(dplyr)

df = data.frame(q = 1, w = 2, e = 3)
    
df %>% rename(A = q, B = e)

#  A w B
#1 1 2 3

Or if you want to use vectors, as suggested by @Jelena-bioinf:

library(dplyr)

df = data.frame(q = 1, w = 2, e = 3)

oldnames = c("q","e")
newnames = c("A","B")

df %>% rename_at(vars(oldnames), ~ newnames)

#  A w B
#1 1 2 3

L. D. Nicolas May suggested a change given rename_at is being superseded by rename_with:

df %>% 
  rename_with(~ newnames[which(oldnames == .x)], .cols = oldnames)

#  A w B
#1 1 2 3

Removed original answer because it was wrong.

The width is ok- but the height resets to 0

so

 min-height: 400px;

When Python2.x sees a == b, it tries the following.

• If type(b) is a new-style class, and type(b) is a subclass of type(a), and type(b) has overridden __eq__, then the result is b.__eq__(a).
• If type(a) has overridden __eq__ (that is, type(a).__eq__ isn't object.__eq__), then the result is a.__eq__(b).
• If type(b) has overridden __eq__, then the result is b.__eq__(a).
• If none of the above are the case, Python repeats the process looking for __cmp__. If it exists, the objects are equal iff it returns zero.
• As a final fallback, Python calls object.__eq__(a, b), which is True iff a and b are the same object.

If any of the special methods return NotImplemented, Python acts as though the method didn't exist.

Note that last step carefully: if neither a nor b overloads ==, then a == b is the same as a is b.

This provides you the code example on sorting map. Basically this is what they provide:

var keys []int
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark1-8      2863149           374 ns/op         152 B/op          5 allocs/op

and this is what I would suggest using instead:

keys := make([]int, 0, len(myMap))
for k := range myMap {
    keys = append(keys, k)
}
sort.Ints(keys)

// Benchmark2-8      5320446           230 ns/op          80 B/op          2 allocs/op

Full code can be found in this Go Playground.

let str = "January,February,March,April,May,June,July,August,September,October,November,December"

let arr = str.split(',');

it will result:

["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

and if you want to convert following to:

["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

this:

"January,February,March,April,May,June,July,August,September,October,November,December";

use:

str = arr.join(',')

gahooa's answer is correct for the question as phrased in the heading, but if the lists are already numpy format or larger than ten it will be MUCH faster (3 orders of magnitude) as well as more readable, to do simple numpy multiplication as suggested by NPE. I get these timings:

0.0049ms -> N = 4, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0075ms -> N = 4, a = [i for i in range(N)], c = a * b
0.0167ms -> N = 4, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 4, a = np.arange(N), c = a * b
0.0171ms -> N = 40, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0095ms -> N = 40, a = [i for i in range(N)], c = a * b
0.1077ms -> N = 40, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 40, a = np.arange(N), c = a * b
0.1485ms -> N = 400, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0397ms -> N = 400, a = [i for i in range(N)], c = a * b
1.0348ms -> N = 400, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0020ms -> N = 400, a = np.arange(N), c = a * b

i.e. from the following test program.

import timeit

init = ['''
import numpy as np
N = {}
a = {}
b = np.linspace(0.0, 0.5, len(a))
'''.format(i, j) for i in [4, 40, 400] 
                  for j in ['[i for i in range(N)]', 'np.arange(N)']]

func = ['''c = [a*b for a,b in zip(a, b)]''',
'''c = a * b''']

for i in init:
  for f in func:
    lines = i.split('\n')
    print('{:6.4f}ms -> {}, {}, {}'.format(
           timeit.timeit(f, setup=i, number=1000), lines[2], lines[3], f))

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

In combination of PHP and MySQL, double quotes and single quotes make your query-writing time so much easier.

$query = "INSERT INTO `table` (`id`, `col1`, `col2`) VALUES (NULL, '$val1', '$val2')";

Now, suppose you are using a direct post variable into the MySQL query then, use it this way:

$query = "INSERT INTO `table` (`id`, `name`, `email`) VALUES (' ".$_POST['id']." ', ' ".$_POST['name']." ', ' ".$_POST['email']." ')";

This is the best practice for using PHP variables into MySQL.

I also made this simple code example on Codepen when I was working with a designer who asked me to show her what it would look like when I asked if I could replace your close button with a coded version rather than an image.

You can use the values 'TRUE' and 'FALSE'. From https://docs.microsoft.com/en-us/sql/t-sql/data-types/bit-transact-sql:

The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.

Use JS String.prototype.replace first argument should be Regex pattern or String and Second argument should be a String or function.

str.replace(regexp|substr, newSubStr|function);

Ex:

var str = 'this is some sample text that i want to replace'; var newstr = str.replace(/want/i, "dont't want"); document.write(newstr); // this is some sample text that i don't want to replace

By default setTextSize, without units work in SP (scales pixel)

public void setTextSize (float size) 
Added in API level 1
Set the default text size to the given value, interpreted as "scaled pixel" units. This 
size is adjusted based on the current density and user font size preference.

what language is this? If you're using a language that passes everything by reference like Java (except for native types), typically you can call .clone() method. The .clone() method is typically implemented by copying/cloning all relevant instance fields into the new object.

not a one-line-code solution, but pretty easy:

sub-class Activity, then override and add finish() to onPause() method

this way, activity will be gone once it enters background, therefore the app won't keep a stack of activities, you can finish() the current activity and the app is gone!

I took a similar approach as Sean3z but instead I have the connection closed everytime i make a query.

His way works if it's only executed on the entry point of your app, but let's say you have controllers that you want to do a var db = require('./db'). You can't because otherwise everytime you access that controller you will be creating a new connection.

To avoid that, i think it's safer, in my opinion, to open and close the connection everytime.

here is a snippet of my code.

mysq_query.js

// Dependencies
var mysql   = require('mysql'),
    config  = require("../config");

/*
 * @sqlConnection
 * Creates the connection, makes the query and close it to avoid concurrency conflicts.
 */
var sqlConnection = function sqlConnection(sql, values, next) {

    // It means that the values hasnt been passed
    if (arguments.length === 2) {
        next = values;
        values = null;
    }

    var connection = mysql.createConnection(config.db);
    connection.connect(function(err) {
        if (err !== null) {
            console.log("[MYSQL] Error connecting to mysql:" + err+'\n');
        }
    });

    connection.query(sql, values, function(err) {

        connection.end(); // close the connection

        if (err) {
            throw err;
        }

        // Execute the callback
        next.apply(this, arguments);
    });
}

module.exports = sqlConnection;

Than you can use it anywhere just doing like

var mysql_query = require('path/to/your/mysql_query');
mysql_query('SELECT * from your_table where ?', {id: '1'}, function(err, rows)   {
    console.log(rows);
});

UPDATED: config.json looks like

{
        "db": {
        "user"     : "USERNAME",
        "password" : "PASSWORD",
        "database" : "DATABASE_NAME",
        "socketPath": "/tmp/mysql.sock"
    }
}

Hope this helps.

You can find their 5-step pem creation process right at the bottom of the page.

You would have to tune it according to your environment.

Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.

Say, instead of

<Connector ... maxThreads="500" acceptCount="50"

you use

<Connector ... maxThreads="300" acceptCount="150"

you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.

In any case, though, you have to do some benchmarks to really know what is best.

The following works for me.

#include <algorithm>
void  toUpperCase(std::string& str)
{
    std::transform(str.begin(), str.end(), str.begin(), ::toupper);
}

int main()
{
   std::string str = "hello";
   toUpperCase(&str);
}

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

I know its an old question, but in terms of listing untracked files I thought I would add another one which also lists untracked folders:

You can used the git clean operation with -n (dry run) to show you which files it will remove (including the .gitignore files) by:

git clean -xdn

This has the advantage of showing all files and all folders that are not tracked. Parameters:

• x - Shows all untracked files (including ignored by git and others, like build output etc...)
• d - show untracked directories
• n - and most importantly! - dryrun, i.e. don't actually delete anything, just use the clean mechanism to display the results.

It can be a little bit unsafe to do it like this incase you forget the -n. So I usually alias it in git config.

Git has a limit of 4096 characters for a filename, except on Windows when Git is compiled with msys. It uses an older version of the Windows API and there's a limit of 260 characters for a filename.

So as far as I understand this, it's a limitation of msys and not of Git. You can read the details here: https://github.com/msysgit/git/pull/110

You can circumvent this by using another Git client on Windows or set core.longpaths to true as explained in other answers.

git config --system core.longpaths true

Git is build as a combination of scripts and compiled code. With the above change some of the scripts might fail. That's the reason for core.longpaths not to be enabled by default.

The windows documentation at https://docs.microsoft.com/en-us/windows/desktop/fileio/naming-a-file has some more information:

Starting in Windows 10, version 1607, MAX_PATH limitations have been removed from common Win32 file and directory functions. However, you must opt-in to the new behavior.

A registry key allows you to enable or disable the new long path behavior. To enable long path behavior set the registry key at HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD)

If you are using the Python wrappers, then (assuming your matrix name is mat):

• mat.shape gives you an array of the type- [height, width, channels]

• mat.size gives you the size of the array

Sample Code:

import cv2
mat = cv2.imread('sample.png')
height, width, channel = mat.shape[:3]
size = mat.size

In Python >= 3.5 using subprocess.run works for me:

import subprocess

cmd = 'echo foo; sleep 1; echo foo; sleep 2; echo foo'
subprocess.run(cmd, shell=True)

(getting the output during execution also works without shell=True) https://docs.python.org/3/library/subprocess.html#subprocess.run

The default configuration of most SMTP servers is not to relay from an untrusted source to outside domains. For example, imagine that you contact the SMTP server for foo.com and ask it to send a message to [email protected]. Because the SMTP server doesn't really know who you are, it will refuse to relay the message. If the server did do that for you, it would be considered an open relay, which is how spammers often do their thing.

If you contact the foo.com mail server and ask it to send mail to [email protected], it might let you do it. It depends on if they trust that you're who you say you are. Often, the server will try to do a reverse DNS lookup, and refuse to send mail if the IP you're sending from doesn't match the IP address of the MX record in DNS. So if you say that you're the bar.com mail server but your IP address doesn't match the MX record for bar.com, then it will refuse to deliver the message.

You'll need to talk to the administrator of that SMTP server to get the authentication information so that it will allow relay for you. You'll need to present those credentials when you contact the SMTP server. Usually it's either a user name/password, or it can use Windows permissions. Depends on the server and how it's configured.

See Unable to send emails to external domain using SMTP for an example of how to send the credentials.

Coming from Python this bugged me. I wrote a simple wrapper/Proxy for node that will accept both positional and keyword objects.

Microsoft Visual Studio 2015 now has options for Android development: C++, Cordova, and C# with Xamarin. When choosing one of those Android development options, Visual Studio will also install the brand new Visual Studio Emulator for Android to use as a target for debugging your app. You can also download the emulator without needing to install Visual Studio. For more details see

I think you are getting confused about what the a:active CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected into your CSS and when you select a link, update the selected menu item with new class e.g.

<div class="menuBar">
    <ul>
        <li class="selected"><a href="index.php">HOME</a></li>
        <li><a href="two.php">PORTFOLIO</a></li>
        ....
    </ul>
</div>

// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; } 
// more general CSS
li.selected a { color: #FF0000; }

You will need to update your template page to take in a selectedPage parameter.

You can redirect stdout to nul to hide it.

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >nul

Just add >nul to the commands you want to hide the output from.

Here you can see all the different ways of redirecting the std streams.

As to UTF-8 is multibite characters string and so you get some problems to work and it's a bad idea/ Instead use normal Unicode.

So by my opinion best is use ordinary ASCII char text with some codding set. Need to use Unicode if you use more than 2 sets of different symbols (languages) in single.

It's rather rare case. In most cases enough 2 sets of symbols. For this common case use ASCII chars, not Unicode.

Effect of using multibute chars like UTF-8 you get only China traditional, arabic or some hieroglyphic text. It's very very rare case!!!

I don't think there are many peoples needs that. So never use UTF-8!!! It's avoid strong headache of manipulate such strings.

Usually I will just use the undocumented proc sp_MSForEachTable

-- disable referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' 
GO 

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?' 
GO 

-- enable referential integrity again 
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL' 
GO

I had this problem using GitExtensions on windows. Fixed by granting full permission for the current user (me) on the folder that contained the repo.

Another time, I even though I was getting the error from Git Extensions, I was able to commit the same files from Visual Studio 2015.

Another time I had to delete the "index" file from the .git folder

Open angular.json file and find budgets keyword.

It should look like:

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

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

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

What does budgets mean?

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

In our case budget is the limit for bundle sizes.

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

You can't use php code client-side. You need to use javascript.

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="document.location.href='some/page'" />

However, you really shouldn't be using inline js (like onclick here). Study about this here: https://www.google.com/search?q=Why+is+inline+js+bad%3F

Here's a clean way of doing this: Live demo (click).

Markup:

<button id="myBtn">Redirect</button>

JavaScript:

var btn = document.getElementById('myBtn');
btn.addEventListener('click', function() {
  document.location.href = 'some/page';
});

If you need to write in the location with php:

  <button id="myBtn">Redirect</button>
  <script>
    var btn = document.getElementById('myBtn');
    btn.addEventListener('click', function() {
      document.location.href = '<?php echo $page; ?>';
    });
  </script>

I met the same issue while experimenting with my own Python library and what I've found out is that pip freeze will show you the library as installed if your current directory contains lib.egg-info folder. And pip uninstall <lib> will give you the same error message.

1. Make sure your current directory doesn't have any egg-info folders
2. Check pip show <lib-name> to see the details about the location of the library, so you can remove files manually.

Regular expressions work pretty well for HTML scraping as well ;-) Though after looking at Beautiful Soup, I can see why this would be a valuable tool.

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

Here's a simple function I made. It accepts a string CSV line and returns an array of fields:

It works well with Excel generated CSV files, and many other variations.

    public static string[] ParseCsvRow(string r)
    {

        string[] c;
        string t;
        List<string> resp = new List<string>();
        bool cont = false;
        string cs = "";

        c = r.Split(new char[] { ',' }, StringSplitOptions.None);

        foreach (string y in c)
        {
            string x = y;


            if (cont)
            {
                // End of field
                if (x.EndsWith("\""))
                {
                    cs += "," + x.Substring(0, x.Length - 1);
                    resp.Add(cs);
                    cs = "";
                    cont = false;
                    continue;

                }
                else
                {
                    // Field still not ended
                    cs += "," + x;
                    continue;
                }
            }

            // Fully encapsulated with no comma within
            if (x.StartsWith("\"") && x.EndsWith("\""))
            {
                if ((x.EndsWith("\"\"") && !x.EndsWith("\"\"\"")) && x != "\"\"")
                {
                    cont = true;
                    cs = x;
                    continue;
                }

                resp.Add(x.Substring(1, x.Length - 2));
                continue;
            }

            // Start of encapsulation but comma has split it into at least next field
            if (x.StartsWith("\"") && !x.EndsWith("\""))
            {
                cont = true;
                cs += x.Substring(1);
                continue;
            }

            // Non encapsulated complete field
            resp.Add(x);

        }

        return resp.ToArray();

    }
