This isn't part of numpy, but it will work with numpy.ndarray objects. A numpy.matrix can be converted to a numpy.ndarray and a numpy.ndarray can be converted to a numpy.matrix.

In MVC 3 I had to add:

using System.ComponentModel.DataAnnotations;

among usings when adding properties:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]

Especially if you are adding these properties in .edmx file like me. I found that by default .edmx files don't have this using so adding only propeties is not enough.

One way which I'm currently using measures the spread of edges in the image. Look for this paper:

@ARTICLE{Marziliano04perceptualblur,
    author = {Pina Marziliano and Frederic Dufaux and Stefan Winkler and Touradj Ebrahimi},
    title = {Perceptual blur and ringing metrics: Application to JPEG2000,” Signal Process},
    journal = {Image Commun},
    year = {2004},
    pages = {163--172} }

It's usually behind a paywall but I've seen some free copies around. Basically, they locate vertical edges in an image, and then measure how wide those edges are. Averaging the width gives the final blur estimation result for the image. Wider edges correspond to blurry images, and vice versa.

This problem belongs to the field of no-reference image quality estimation. If you look it up on Google Scholar, you'll get plenty of useful references.

EDIT

Here's a plot of the blur estimates obtained for the 5 images in nikie's post. Higher values correspond to greater blur. I used a fixed-size 11x11 Gaussian filter and varied the standard deviation (using imagemagick's convert command to obtain the blurred images).

If you compare images of different sizes, don't forget to normalize by the image width, since larger images will have wider edges.

Finally, a significant problem is distinguishing between artistic blur and undesired blur (caused by focus miss, compression, relative motion of the subject to the camera), but that is beyond simple approaches like this one. For an example of artistic blur, have a look at the Lenna image: Lenna's reflection in the mirror is blurry, but her face is perfectly in focus. This contributes to a higher blur estimate for the Lenna image.

I stumbled upon this problem during attempt to dockerise Avahi which needs to be aware of its public IP to function properly. Assigning static IP to the container is tricky due to lack of support for static IP assignment in Docker.

This article describes technique how to assign static IP to the container on Debian:

1. Docker service should be started with DOCKER_OPTS="--bridge=br0 --ip-masq=false --iptables=false". I assume that br0 bridge is already configured.

2. Container should be started with --cap-add=NET_ADMIN --net=bridge

3. Inside container pre-up ip addr flush dev eth0 in /etc/network/interfaces can be used to dismiss IP address assigned by Docker as in following example:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
    pre-up ip addr flush dev eth0
    address 192.168.0.249
    netmask 255.255.255.0
    gateway 192.168.0.1

4. Container's entry script should begin with /etc/init.d/networking start. Also entry script needs to edit or populate /etc/hosts file in order to remove references to Docker-assigned IP.

The answers here are worth a try, but you should also review your code. Specifically have a read of Polyfun's answer here: How to get rid of deadlock in a SQL Server 2005 and C# application?

It explains the concurrency issue, and how the usage of "with (updlock)" in your queries might correct your deadlock situation - depending really on exactly what your code is doing. If your code does follow this pattern, this is likely a better fix to make, before resorting to dirty reads, etc.

Also it's important to pay attention if the property android:inputType is textMultiLine. If so, the properties android:singleLine, android:imeOptions, android:ellipsize and android maxLines will be ignored and your EditText will accepted MultiLines anyway.

Preflight is a web security feature implemented by the browser. For Chrome you can disable all web security by adding the --disable-web-security flag.

For example: "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:\newChromeSettingsWithoutSecurity" . You can first create a new shortcut of chrome, go to its properties and change the target as above. This should help!

I made a function version of Oscar's answer, this one also copies the environment and changes to the appropriate directory

function new_window {
    TMP_FILE=$(mktemp "/tmp/command.XXXXXX")
    echo "#!/usr/bin/env bash" > $TMP_FILE

    # Copy over environment (including functions), but filter out readonly stuff
    set | grep -v "\(BASH_VERSINFO\|EUID\|PPID\|SHELLOPTS\|UID\)" >> $TMP_FILE

    # Copy over exported envrionment
    export -p >> $TMP_FILE

    # Change to directory
    echo "cd $(pwd)" >> $TMP_FILE

    # Copy over target command line
    echo "$@" >> $TMP_FILE

    chmod +x "$TMP_FILE"
    open -b com.apple.terminal "$TMP_FILE"

    sleep .1 # Wait for terminal to start
    rm "$TMP_FILE"
}

You can use it like this:

new_window my command here

or

new_window ssh example.com

i was trying allot of slutions but none was working on both iPhone and Android!

now for me it's ok to disable the zoom because the website was mobile-first design!

1 - right click the highlight whose color you want to change

2 - select "Properties" in the popup menu

3 - choose the new color (as coobird suggested)

This solution is easy because you dont have to search for the highlight by its name ("Ocurrence" or "Write Ocurrence" etc), just right click and the appropriate window is shown.

document.getElementById('foo').disabled = true;

or

document.getElementById('foo').readOnly = true;

Note that readOnly should be in camelCase to work correctly in Firefox (magic).

Demo: https://jsfiddle.net/L96svw3c/ -- somewhat explains the difference between disabled and readOnly.

I am so used to just doing this with a Data Dictionary in Objective C. It was harder to get a similar result in Java for Android. I ended up creating a custom class, and then just doing a hashmap of my custom class.

public class Test1 {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.addview);

//create the datastring
    HashMap<Integer, myClass> hm = new HashMap<Integer, myClass>();
    hm.put(1, new myClass("Car", "Small", 3000));
    hm.put(2, new myClass("Truck", "Large", 4000));
    hm.put(3, new myClass("Motorcycle", "Small", 1000));

//pull the datastring back for a specific item.
//also can edit the data using the set methods.  this just shows getting it for display.
    myClass test1 = hm.get(1);
    String testitem = test1.getItem();
    int testprice = test1.getPrice();
    Log.i("Class Info Example",testitem+Integer.toString(testprice));
}
}

//custom class.  You could make it public to use on several activities, or just include in the activity if using only here
class myClass{
    private String item;
    private String type;
    private int price;

    public myClass(String itm, String ty, int pr){
        this.item = itm;
        this.price = pr;
        this.type = ty;
    }

    public String getItem() {
        return item;
    }

    public void setItem(String item) {
        this.item = item;
    }

    public String getType() {
        return item;
    }

    public void setType(String type) {
        this.type = type;
    }

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

}

With the latest version of Xcode (3.2.2), you can drag and drop any crash reports into the Device Logs section of the Xcode Organiser and they will automatically by symbolicated for you. I think this works best if you built that version of the App using Build & Archive (also part of Xcode 3.2.2)

I have found an excellent and relatively short explanation here.

A multipart request is a REST request containing several packed REST requests inside its entity.

C# supports some inherited covariance for event delegates, so a method like this:

void LowestCommonHander( object sender, EventArgs e ) { ... } 

Can be used to subscribe to your event, no explicit cast required

gcInt.MyEvent += LowestCommonHander;

You can even use lambda syntax and the intellisense will all be done for you:

gcInt.MyEvent += (sender, e) =>
{
    e. //you'll get correct intellisense here
};

DataSet ds = new DataSet();

DataTable activity = DTsetgvActivity.Copy();
activity.TableName = "activity";
ds.Tables.Add(activity);

Honer.TableName = "Honer";
ds.Tables.Add(Honer);

DataTable Property = DTsetgvProperty.Copy();

Updated Answer

^{* Updated answer which support the v2.1.1** bootstrap version stylesheet.}

^{**But be careful because this solution has been removed from v3}

Just wanted to point out that this solution is not needed anymore as the latest bootstrap now supports multi-level dropdowns by default. You can still use it if you're on older versions but for those who updated to the latest (v2.1.1 at the time of writing) it is not needed anymore. Here is a fiddle with the updated default multi-level dropdown straight from the documentation:

http://jsfiddle.net/2Smgv/2858/

Original Answer

There have been some issues raised on submenu support over at github and they are usually closed by the bootstrap developers, such as this one, so i think it is left to the developers using the bootstrap to work something out. Here is a demo i put together showing you how you can hack together a working sub-menu.

Relevant code

CSS

.dropdown-menu .sub-menu {
    left: 100%;
    position: absolute;
    top: 0;
    visibility: hidden;
    margin-top: -1px;
}

.dropdown-menu li:hover .sub-menu {
    visibility: visible;
    display: block;
}

.navbar .sub-menu:before {
    border-bottom: 7px solid transparent;
    border-left: none;
    border-right: 7px solid rgba(0, 0, 0, 0.2);
    border-top: 7px solid transparent;
    left: -7px;
    top: 10px;
}
.navbar .sub-menu:after {
    border-top: 6px solid transparent;
    border-left: none;
    border-right: 6px solid #fff;
    border-bottom: 6px solid transparent;
    left: 10px;
    top: 11px;
    left: -6px;
}

Created my own .sub-menu class to apply to the 2-level drop down menus, this way we can position them next to our menu items. Also modified the arrow to display it on the left of the submenu group.

Demo

echo "blahblah"> txt.txt will erase the txt and put blahblah in it's place

echo "blahblah">> txt.txt will write blahblah on a new line in the txt

I think that both will create a new txt if none exists (I know that the first one does)

Where "txt.txt" is written above, a file path can be inserted if wanted. e.g. C:\Users\<username>\desktop, which will put it on their desktop.

Build an expression that matches, and use !match()... (logical negation) That's probably how grep does anyway...

This works for me:

    ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    // Mobile
    State mobile = conMan.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState();

    // Wi-Fi
    State wifi = conMan.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();

    // And then use it like this:

    if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING)
    {
        Toast.makeText(Wifi_Gprs.this,"Mobile is Enabled :) ....",Toast.LENGTH_LONG).show();
    }
    else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING)
    {
        Toast.makeText(Wifi_Gprs.this,"Wifi is Enabled  :) ....",Toast.LENGTH_LONG).show();
    }
    else
    {
        Toast.makeText(Wifi_Gprs.this,"No Wifi or Gprs Enabled :( ....",Toast.LENGTH_LONG).show();
    }

And add this permission:

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

I had a similar issue when I tried to get a pull with a single quote ' in it's name.

I had to escape the pull request name:

git pull https://github.com/foo/bar namewithsingle"'"quote

There is no guarantee that your threads are executing simultaneously regardless of any trivial example anyone else posts. If your OS only gives the java process one processor to work on, your java threads will still be scheduled for each time slice in a round robin fashion. Meaning, no two will ever be executing simultaneously, but the work they do will be interleaved. You can use monitoring tools like Java's Visual VM (standard in the JDK) to observe the threads executing in a Java process.

List is the preferred way in java 1.5 and beyond as it can use generics. Arrays cannot have generics. Also Arrays have a pre defined length, which cannot grow dynamically. Initializing an array with a large size is not a good idea. ArrayList is the the way to declare an array with generics and it can dynamically grow. But if delete and insert is used more frequently, then linked list is the fastest data structure to be used.

If you have a pandas serie with NaN, and want to remove it (without loosing index):

serie = serie.dropna()

# create data for example
data = np.array(['g', 'e', 'e', 'k', 's']) 
ser = pd.Series(data)
ser.replace('e', np.NAN)
print(ser)

0      g
1    NaN
2    NaN
3      k
4      s
dtype: object

# the code
ser = ser.dropna()
print(ser)

0    g
3    k
4    s
dtype: object

You can either use:

• return X. this will return only one value.

• return object. will return a full object. For example your object might include X, Y, and Z values.

• pass array. arrays are passed by reference. i.e. if you pass array of integers, modified the array inside the method, then the original code will see the changes.

Example on passing Array.

void methodOne{
    int [] arr = {1,2,3};
    methodTwo(arr);
    ...//print arr here
}
void methodTwo(int [] arr){
    for (int i=0; i<arr.length;i++){
         arr[i]+=3;
    }
}

This will print out: 4,5,6.

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

Your problem is here:

2013-11-14 17:57:20 5180 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode

There's some problem with the ibdata1 file - maybe the permissions have changed on it? Perhaps some other process has it open. Does it even exist?

Fix this and possibly everything else will fall into place.

That is because in Python 3, they have replaced the print statement with the print function.

The syntax is now more or less the same as before, but it requires parens:

From the "what's new in python 3" docs:

Old: print "The answer is", 2*2
New: print("The answer is", 2*2)

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Old: print              # Prints a newline
New: print()            # You must call the function!

Old: print >>sys.stderr, "fatal error"
New: print("fatal error", file=sys.stderr)

Old: print (x, y)       # prints repr((x, y))
New: print((x, y))      # Not the same as print(x, y)!

Use SVD or QR-decomposition to calculate exact solution in real or complex number fields:

numpy.linalg.svd numpy.linalg.qr

Another excellent fractal to learn is the Sierpinski Triangle Fractal.

Basically, draw three corners of a triangle (an equilateral is preferred, but any triangle will work), then start a point P at one of those corners. Move P halfway to any of the 3 corners at random, and draw a point there. Again move P halfway towards any random corner, draw, and repeat.

You'd think the random motion would create a random result, but it really doesn't.

Reference: http://en.wikipedia.org/wiki/Sierpinski_triangle

The task must be configured in two steps.

First you create a simple task that start at 0:00, every day. Then, you go in Advanced... (or similar depending on the operating system you are on) and select the Repeat every X minutes option for 24 hours.

The key here is to find the advanced properties. If you are using the XP wizard, it will only offer you to launch the advanced dialog once you created the task.

On more recent versions of Windows (7+ I think?):

1. Double click the task and a property window will show up.
2. Click the Triggers tab.
3. Double click the trigger details and the Edit Trigger window will show up.
4. Under Advanced settings panel, tick Repeat task every xxx minutes, and set Indefinitely if you need.
5. Finally, click ok.

It does 5 things:

1. It creates a new object. The type of this object is simply object.
2. It sets this new object's internal, inaccessible, [[prototype]] (i.e. __proto__) property to be the constructor function's external, accessible, prototype object (every function object automatically has a prototype property).
3. It makes the this variable point to the newly created object.
4. It executes the constructor function, using the newly created object whenever this is mentioned.
5. It returns the newly created object, unless the constructor function returns a non-null object reference. In this case, that object reference is returned instead.

Note: constructor function refers to the function after the new keyword, as in

new ConstructorFunction(arg1, arg2)

Once this is done, if an undefined property of the new object is requested, the script will check the object's [[prototype]] object for the property instead. This is how you can get something similar to traditional class inheritance in JavaScript.

The most difficult part about this is point number 2. Every object (including functions) has this internal property called [[prototype]]. It can only be set at object creation time, either with new, with Object.create, or based on the literal (functions default to Function.prototype, numbers to Number.prototype, etc.). It can only be read with Object.getPrototypeOf(someObject). There is no other way to set or read this value.

Functions, in addition to the hidden [[prototype]] property, also have a property called prototype, and it is this that you can access, and modify, to provide inherited properties and methods for the objects you make.

Here is an example:

ObjMaker = function() {this.a = 'first';};
// ObjMaker is just a function, there's nothing special about it that makes 
// it a constructor.

ObjMaker.prototype.b = 'second';
// like all functions, ObjMaker has an accessible prototype property that 
// we can alter. I just added a property called 'b' to it. Like 
// all objects, ObjMaker also has an inaccessible [[prototype]] property
// that we can't do anything with

obj1 = new ObjMaker();
// 3 things just happened.
// A new, empty object was created called obj1.  At first obj1 was the same
// as {}. The [[prototype]] property of obj1 was then set to the current
// object value of the ObjMaker.prototype (if ObjMaker.prototype is later
// assigned a new object value, obj1's [[prototype]] will not change, but you
// can alter the properties of ObjMaker.prototype to add to both the
// prototype and [[prototype]]). The ObjMaker function was executed, with
// obj1 in place of this... so obj1.a was set to 'first'.

obj1.a;
// returns 'first'
obj1.b;
// obj1 doesn't have a property called 'b', so JavaScript checks 
// its [[prototype]]. Its [[prototype]] is the same as ObjMaker.prototype
// ObjMaker.prototype has a property called 'b' with value 'second'
// returns 'second'

It's like class inheritance because now, any objects you make using new ObjMaker() will also appear to have inherited the 'b' property.

If you want something like a subclass, then you do this:

SubObjMaker = function () {};
SubObjMaker.prototype = new ObjMaker(); // note: this pattern is deprecated!
// Because we used 'new', the [[prototype]] property of SubObjMaker.prototype
// is now set to the object value of ObjMaker.prototype.
// The modern way to do this is with Object.create(), which was added in ECMAScript 5:
// SubObjMaker.prototype = Object.create(ObjMaker.prototype);

SubObjMaker.prototype.c = 'third';  
obj2 = new SubObjMaker();
// [[prototype]] property of obj2 is now set to SubObjMaker.prototype
// Remember that the [[prototype]] property of SubObjMaker.prototype
// is ObjMaker.prototype. So now obj2 has a prototype chain!
// obj2 ---> SubObjMaker.prototype ---> ObjMaker.prototype

obj2.c;
// returns 'third', from SubObjMaker.prototype

obj2.b;
// returns 'second', from ObjMaker.prototype

obj2.a;
// returns 'first', from SubObjMaker.prototype, because SubObjMaker.prototype 
// was created with the ObjMaker function, which assigned a for us

I read a ton of rubbish on this subject before finally finding this page, where this is explained very well with nice diagrams.

your data is something like this "{"model": "ID":0,"ProductID":6,"PartNumber":7,"VendorID":8}}" web api controller cannot bind it to Your model

I'm using Debian, and I was unable to use tilde for the path. Originally I was using

curl -c "~/cookie" http://localhost:5000/login -d username=myname password=mypassword

I had to change this to:

curl -c "/tmp/cookie" http://localhost:5000/login -d username=myname password=mypassword

-c creates the cookie, -b uses the cookie

so then I'd use for instance:

curl -b "/tmp/cookie" http://localhost:5000/getData

Unicode is a standard which provides a unique number for every character. These unique numbers are called code points (which is just unique code) to all characters existing in the world (some's are still to be added).

For different purposes, you might need to represent this code points in bytes (most programming languages do so), and here's where Character Encoding kicks in.

UTF-8, UTF-16, UTF-32 and so on are all Character Encodings, and Unicode's code points are represented in these encodings, in different ways.

UTF-8 encoding has a variable-width length, and characters, encoded in it, can occupy 1 to 4 bytes inclusive;

UTF-16 has a variable length and characters, encoded in it, can take either 1 or 2 bytes (which is 8 or 16 bits). This represents only part of all Unicode characters called BMP (Basic Multilingual Plane) and it's enough for almost all the cases. Java uses UTF-16 encoding for its strings and characters;

UTF-32 has fixed length and each character takes exactly 4 bytes (32 bits).

You can un-check the build automatically in Project menu and then build by hand by type Ctrl + B, or clicking an icon the appears to the right of the printer icon.

I tried lots of method but below work like charm....

After this command run these :-

curl -sL https://deb.nodesource.com/setup_14.x 565 | sudo -E bash -
sudo apt-get install -y nodejs

Now check…

node -v
npm -v

If you are using the certificate in a new computer or not. The easiest thing to do would be to revoke the previous certificate relating to the project. Then re-upload to the store. Xcode will generate a new one.

Use a simple method in php copy()

copy($source_url, $local_path_with_file_name);

Note: if the destination file already exists, it will be overwritten

PHP copy() Function

Note: You need to set permission 777 for the destination folder. Use this method when you are downloading to your local machine.

Special Note: 777 is a permission in Unix based system with full read/write/execute permission to owner, group and everyone. In general we give this permission to assets which are not much needed to be hidden from public on a web server. Example: images folder.

return in function return execution back to caller and exit from function terminates the program.

in main function return 0 or exit(0) are same but if you write exit(0) in different function then you program will exit from that position.

returning different values like return 1 or return -1 means that program is returning error .

When exit(0) is used to exit from program, destructors for locally scoped non-static objects are not called. But destructors are called if return 0 is used.

I disagree with the previous answers suggesting ArrayList, because ArrayList is not a Dynamic Array but a List backed by an array. The difference is that you cannot do the following:

ArrayList list = new ArrayList(4);
list.put(3,"Test");

It will give you an IndexOutOfBoundsException because there is no element at this position yet even though the backing array would permit such an addition. So you need to use a custom extendable Array implementation like suggested by @randy-lance

I usually host the image on the site, this can link to any hosted image. Just toss this in the readme. Works for .rst files, not sure about .md

function sort() only is only good if your number has same digit, example:

var myData = ["3","11","1","2"]

will return;

var myData = ["1","11","2","3"]

and here improvement for function from mrmonkington

myData.sort().sort(function(a,b){return a - b;}).filter(function(el,i,a){if(i==a.indexOf(el) & el.length>0)return 1;return 0;})

the above function will also delete empty array and you can checkout the demo below

By using transform: works like a charm!

<div class="parent">
    <span>center content using transform</span>
    </div>

    //CSS
    .parent {
        position: relative;
        height: 200px;
        border: 1px solid;
    }
    .parent span {
        position: absolute;
        top: 50%;
        left: 50%;
        -webkit-transform: translate(-50%, -50%);
        transform: translate(-50%, -50%);
    }

It looks like you may be confused as to when commands are run. In your example, you are calling the get method before the GUI has a chance to be displayed on the screen (which happens after you call mainloop.

Try adding a button that calls the get method. This is much easier if you write your application as a class. For example:

import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.button = tk.Button(self, text="Get", command=self.on_button)
        self.button.pack()
        self.entry.pack()

    def on_button(self):
        print(self.entry.get())

app = SampleApp()
app.mainloop()

Run the program, type into the entry widget, then click on the button.

On Windows OS create a file and give it a invalid character like \ in the filename. As a result you will get a popup with all the invalid characters in a filename.

no need to do a replacement. the regex will give you what u wanted directly:

"(?<=_)[^_]*\.jpg"

tested with grep:

 echo "3.04_somename.jpg"|grep -oP "(?<=_)[^_]*\.jpg"
somename.jpg

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

1. Performance:

Assume your where clause is like this:

WHERE NAME='JON'

If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.

2. Character set:

If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.

Firstly, try / except are not functions, but statements.

To convert a string (or any other type that can be converted) to an integer in Python, simply call the int() built-in function. int() will raise a ValueError if it fails and you should catch this specifically:

In Python 2.x:

>>> for value in '12345', 67890, 3.14, 42L, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print '%s as an int is %d' % (str(value), int(value))
...     except ValueError as ex:
...         print '"%s" cannot be converted to an int: %s' % (value, ex)
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

In Python 3.x

the syntax has changed slightly:

>>> for value in '12345', 67890, 3.14, 42, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print('%s as an int is %d' % (str(value), int(value)))
...     except ValueError as ex:
...         print('"%s" cannot be converted to an int: %s' % (value, ex))
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

I had a requirement where in the Firstname and Lastname are user inputs which were required fields and user should not be able to hit space as the first character.

Import AbstractControl from node_modules.

import { AbstractControl } from '@angular/forms';

check if the first character is space If yes then blank the value and return required: true. If no return null

export function spaceValidator(control: AbstractControl) {
if (control && control.value && !control.value.replace(/\s/g, '').length) {
    control.setValue('');
    console.log(control.value);
    return { required: true }
}
else {
    return null;
}
}

the above code will trigger an error if the first character is space and will not allow space to be the first character.

And in form builder group declare

this.paInfoForm = this.formBuilder.group({
        paFirstName: ['', [Validators.required, spaceValidator]],
        paLastName: ['', [Validators.required, spaceValidator]]
})

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

I want to add something on @Michael Laffargue's post:

jqXHR.done() is faster!

jqXHR.success() have some load time in callback and sometimes can overkill script. I find that on hard way before.

UPDATE:

Using jqXHR.done(), jqXHR.fail() and jqXHR.always() you can better manipulate with ajax request. Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster. Good example:

/* Initialize some your AJAX function */
function call_ajax(attr){
    var settings=$.extend({
        call            : 'users',
        option          : 'list'
    }, attr );

    return $.ajax({
        type: "POST",
        url: "//exapmple.com//ajax.php",
        data: settings,
        cache : false
    });
}

/* .... Somewhere in your code ..... */

call_ajax({
    /* ... */
    id : 10,
    option : 'edit_user'
    change : {
          name : 'John Doe'
    }
    /* ... */
}).done(function(data){

    /* DO SOMETHING AWESOME */

});

You don't need substr or strip.

input(monyy,date9.);

I like the simplicity of tabulary package:

\usepackage{tabulary}
...
\begin{tabulary}{\linewidth}{LCL}
    \hline
    Short sentences      & \#  & Long sentences                                                 \\
    \hline
    This is short.       & 173 & This is much loooooooonger, because there are many more words.  \\
    This is not shorter. & 317 & This is still loooooooonger, because there are many more words. \\
    \hline
\end{tabulary} 

In the example, you arrange the whole width of the table with respect to \textwidth. E.g 0.4 of it. Then the rest is automatically done by the package.

Most of the example is taken from http://en.wikibooks.org/wiki/LaTeX/Tables .

The answer is a simple PowerShell one-liner:

Get-WmiObject Win32_NetworkConnection | ft "RemoteName","LocalName" -A

If you only want to pull the UNC for one particular drive, add a where statement:

Get-WmiObject Win32_NetworkConnection | where -Property 'LocalName' -eq 'Z:'  | ft "RemoteName","LocalName" -A

I know this is old but none of the above solutions worked for me. After extensive debugging, I figured out the issue. The solution is setting the android:windowTranslucentStatus attribute to false in my styles.xml

You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.

This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

There's been a fair amount of recent research in considering how REST HTTP calls could replace the message queue concept.

If you introduce the concept of a process and a task as a resource, the need for middle messaging layer starts to evaporate.

Ex:

POST /task/name
    - Returns a 202 accepted status immediately
    - Returns a resource url for the created task: /task/name/X
    - Returns a resource url for the started process: /process/Y

GET /process/Y
    - Returns status of ongoing process

A task can have multiple steps for initialization, and a process can return status when polled or POST to a callback URL when complete.

This is dead simple, and becomes quite powerful when you realize that you can now subscribe to an rss/atom feed of all running processes and tasks without any middle layer. Any queuing system is going to require some sort of web front end anyway, and this concept has it built in without another layer of custom code.

Your resources exist until you delete them, which means you can view historical information long after the process and task complete.

You have built in service discovery, even for a task that has multiple steps, without any extra complicated protocols.

GET /task/name
    - returns form with required fields

POST (URL provided form's "action" attribute)

Your service discovery is an HTML form - a universal and human readable format.

The entire flow can be used programmatically or by a human, using universally accepted tools. It's a client driven, and therefore RESTful. Every tool created for the web can drive your business processes. You still have alternate message channels by POSTing asynchronously to a separate array of log servers.

After you consider it for a while, you sit back and start to realize that REST may just eliminate the need for a messaging queue and an ESB altogether.

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

In Ef .net core there are two options that you can do; first with data annotations:

public class Blog
{
    public int BlogId { get; set; }
    [Required]
    public string Url { get; set; }
}

Or with fluent api:

class MyContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Blog>()
            .Property(b => b.Url)
            .IsRequired(false)//optinal case
            .IsRequired()//required case
            ;
    }
}

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}

There are more details here

if ($(".mydivclass").size()){
   // code here
}

The size() method just returns the number of elements that the jQuery selector selects - in this case the number of elements with the class mydivclass. If it returns 0, the expression is false, and therefore there are none, and if it returns any other number, the divs must exist.

You cannot create a table with a name that is identical to an existing table or view in the cluster. To modify an existing table, use ALTER TABLE (link), or to drop all data currently in the table and create an empty table with the desired schema, issue DROP TABLE before CREATE TABLE.

It could be that the sequence you are creating is the culprit. In PostgreSQL, sequences are implemented as a table with a particular set of columns. If you already have the sequence defined, you should probably skip creating it. Unfortunately, there's no equivalent in CREATE SEQUENCE to the IF NOT EXISTS construct available in CREATE TABLE. By the looks of it, you might be creating your schema unconditionally, anyways, so it's reasonable to use

DROP TABLE IF EXISTS csd_relationship;
DROP SEQUENCE IF EXISTS csd_relationship_csd_relationship_id_seq;

before the rest of your schema update; In case it isn't obvious, This will delete all of the data in the csd_relationship table, if there is any

This is not the same as using a sequence. When using a sequence, you are not inserting or updating anything. You are simply retrieving the next sequence value. It looks like hibernate does not support it.

create external table table_name( 
Year int, 
Month int,
column_name data_type ) 
row format delimited fields terminated by ',' 
location '/user/user_name/example_data' TBLPROPERTIES('serialization.null.format'='', 'skip.header.line.count'='1');

Pure CSS solution, using calc

.modal-body {
    max-height: calc(100vh - 200px);
    overflow-y: auto;
}

200px may be adjusted in accordance to height of header & footer

This is a lot simpler with .slideToggle():

jQuery('.class1 a').click( function() {
  $(this).next('.class2').slideToggle();
});

EDIT: made it .next instead of .siblings

http://www.mredesign.com/demos/jquery-effects-1/

You can also add cookie's to remember where you're at...

http://c.hadcoleman.com/2008/09/jquery-slide-toggle-with-cookie/

input_str = "ABC"
[bin(byte) for byte in bytes(input_str, "utf-8")]

Will give:

['0b1000001', '0b1000010', '0b1000011']

There are pieces to this answer that helped me get what I needed (easy multi-line concatenation WITHOUT extra whitespace), but since none of the actual answers had it, I'm compiling them here:

str = 'this is a multi-line string'\
  ' using implicit concatenation'\
  ' to prevent spare \n\'s'

=> "this is a multi-line string using implicit concatenation to eliminate spare
\\n's"

As a bonus, here's a version using funny HEREDOC syntax (via this link):

p <<END_SQL.gsub(/\s+/, " ").strip
SELECT * FROM     users
         ORDER BY users.id DESC
END_SQL
# >> "SELECT * FROM users ORDER BY users.id DESC"

The latter would mostly be for situations that required more flexibility in the processing. I personally don't like it, it puts the processing in a weird place w.r.t. the string (i.e., in front of it, but using instance methods that usually come afterward), but it's there. Note that if you are indenting the last END_SQL identifier (which is common, since this is probably inside a function or module), you will need to use the hyphenated syntax (that is, p <<-END_SQL instead of p <<END_SQL). Otherwise, the indenting whitespace causes the identifier to be interpreted as a continuation of the string.

This doesn't save much typing, but it looks nicer than using + signs, to me.

Also (I say in an edit, several years later), if you're using Ruby 2.3+, the operator <<~ is also available, which removes extra indentation from the final string. You should be able to remove the .gsub invocation, in that case (although it might depend on both the starting indentation and your final needs).

EDIT: Adding one more:

p %{
SELECT * FROM     users
         ORDER BY users.id DESC
}.gsub(/\s+/, " ").strip
# >> "SELECT * FROM users ORDER BY users.id DESC"

As an alternative to Node’s answer, if you use InnoDB and defined FK’s you could query the information_schema database e.g.:

SELECT CONSTRAINT_NAME, TABLE_NAME, REFERENCED_TABLE_NAME
FROM information_schema.REFERENTIAL_CONSTRAINTS
WHERE CONSTRAINT_SCHEMA = '<schema>'
AND TABLE_NAME = '<table>'

for foreign keys from <table>, or

SELECT CONSTRAINT_NAME, TABLE_NAME, REFERENCED_TABLE_NAME
FROM information_schema.REFERENTIAL_CONSTRAINTS
WHERE CONSTRAINT_SCHEMA = '<schema>'
AND REFERENCED_TABLE_NAME = '<table>'

for foreign keys to <table>

You can also get the UPDATE_RULE and DELETE_RULE if you want them.

self.navigationController != nil would mean it's in a navigation stack.

I liked @KyleMit's answer on how to make an unstyled input group, but in my case, I only wanted the right side unstyled - I still wanted to use an input-group-addon on the left side and have it look like normal bootstrap. So, I did this:

css

.input-group.input-group-unstyled-right input.form-control {
    border-top-right-radius: 4px;
    border-bottom-right-radius: 4px;
}
.input-group-unstyled-right .input-group-addon.input-group-addon-unstyled {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

html

<div class="input-group input-group-unstyled-right">
    <span class="input-group-addon">
        <i class="fa fa-envelope-o"></i>
    </span>
    <input type="text" class="form-control">
    <span class="input-group-addon input-group-addon-unstyled">
        <i class="fa fa-check"></i>
    </span>
</div>

Class.cast() is rarely ever used in Java code. If it is used then usually with types that are only known at runtime (i.e. via their respective Class objects and by some type parameter). It is only really useful in code that uses generics (that's also the reason it wasn't introduced earlier).

It is not similar to reinterpret_cast, because it will not allow you to break the type system at runtime any more than a normal cast does (i.e. you can break generic type parameters, but can't break "real" types).

The evils of the C-style cast operator generally don't apply to Java. The Java code that looks like a C-style cast is most similar to a dynamic_cast<>() with a reference type in Java (remember: Java has runtime type information).

Generally comparing the C++ casting operators with Java casting is pretty hard since in Java you can only ever cast reference and no conversion ever happens to objects (only primitive values can be converted using this syntax).

With version 1.2.0-alpha06 of material design library, now we can use android:background="..." on MaterialButton components:

<com.google.android.material.button.MaterialButton
    android:background="#fff"
    ...
/>

No you are not required to close anything BUT the connection. Per JDBC specs closing any higher object will automatically close lower objects. Closing Connection will close any Statements that connection has created. Closing any Statement will close all ResultSets that were created by that Statement. Doesn't matter if Connection is poolable or not. Even poolable connection has to clean before returning to the pool.

Of course you might have long nested loops on the Connection creating lots of statements, then closing them is appropriate. I almost never close ResultSet though, seems excessive when closing Statement or Connection WILL close them.

As of PHP 5.6 @$filePath will not work in CURLOPT_POSTFIELDS without CURLOPT_SAFE_UPLOAD being set and it is completely removed in PHP 7. You will need to use a CurlFile object, RFC here.

$fields = [
    'name' => new \CurlFile($filePath, 'image/png', 'filename.png')
];
curl_setopt($resource, CURLOPT_POSTFIELDS, $fields);

Descendants will do exactly what you need, but be sure that you have included a namespace name together with element's name. If you omit it, you will probably get an empty list.

I know I'm late to party, but for everyone else who comes to visit this page, u could try this, it's easier than everything there and makes more sense:

namespace texs {
    typedef std::string Type;
    Type apple = "apple";
    Type wood = "wood";
}

You should use this:

<Link to={this.props.myroute} onClick={hello}>Here</Link>

Or (if method hello lays at this class):

<Link to={this.props.myroute} onClick={this.hello}>Here</Link>

Update: For ES6 and latest if you want to bind some param with click method, you can use this:

    const someValue = 'some';  
....  
    <Link to={this.props.myroute} onClick={() => hello(someValue)}>Here</Link>

Now we have Icon Button to achieve rounded button click and overlay. However background color is not yet available but the same can be achieved by Circle avatar widget as follows:

CircleAvatar(
            backgroundColor: const Color(0xffF4F3FA),
            child: IconButton(
              onPressed: () => FlushbarHelper.createInformation(
                      message: 'Work in progress...')
                  .show(context),
              icon: Icon(Icons.more_vert),
            ),
          ),

Hope this helps some one.

If this is UNIX:

sort -k 2 file.txt

You can use multiple -k flags to sort on more than one column. For example, to sort by family name then first name as a tie breaker:

sort -k 2,2 -k 1,1 file.txt

Relevant options from "man sort":

-k, --key=POS1[,POS2]

start a key at POS1, end it at POS2 (origin 1)

POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.

-t, --field-separator=SEP

use SEP instead of non-blank to blank transition

Meanwhile I do in general no more use

Bundle savedInstanceState & Co

The life cycle is for most activities too complicated and not necessary.

And Google states itself, it is NOT even reliable.

My way is to save any changes immediately in the preferences:

 SharedPreferences p;
 p.edit().put(..).commit()

In some way SharedPreferences work similar like Bundles. And naturally and at first such values have to be read from preferences.

In the case of complex data you may use SQLite instead of using preferences.

When applying this concept, the activity just continues to use the last saved state, regardless of whether it was an initial open with reboots in between or a reopen due to the back stack.

You can get other constructors with getConstructor(...).

    static File mainFolder = new File("Folder");
    public static void main(String[] args) {

        lf.getFiles(lf.mainFolder);
    }
    public void getFiles(File f) {
        File files[];
        if (f.isFile()) {
            String name=f.getName();

        } else {
            files = f.listFiles();
            for (int i = 0; i < files.length; i++) {
                getFiles(files[i]);
            }
        }
    }

The SuppressWarning annotation is used to suppress compiler warnings for the annotated element. Specifically, the unchecked category allows suppression of compiler warnings generated as a result of unchecked type casts.

The RSACryptoServiceProvider(CspParameters) constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.

It sounds as if you are not interested in having the key stored on the machine.

So use the RSACryptoServiceProvider(Int32) constructor:

public static void AssignNewKey(){
    RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

EDIT:

Alternatively try setting the PersistKeyInCsp to false:

public static void AssignNewKey(){
    const int PROVIDER_RSA_FULL = 1;
    const string CONTAINER_NAME = "KeyContainer";
    CspParameters cspParams;
    cspParams = new CspParameters(PROVIDER_RSA_FULL);
    cspParams.KeyContainerName = CONTAINER_NAME;
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
    rsa = new RSACryptoServiceProvider(cspParams);

    rsa.PersistKeyInCsp = false;

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

I wanted a one-time solution:

ssh -o ServerAliveInterval=60 [email protected]

Stored it in an alias:

alias sshprod='ssh -v -o ServerAliveInterval=60 [email protected]'

Now can connect like this:

me@MyMachine:~$ sshprod

You can use a middleware to set the default Content-Type, and set Content-Type differently for particular APIs. Here is an example:

const express = require('express');
const app = express();

const port = process.env.PORT || 3000;

const server = app.listen(port);

server.timeout = 1000 * 60 * 10; // 10 minutes

// Use middleware to set the default Content-Type
app.use(function (req, res, next) {
    res.header('Content-Type', 'application/json');
    next();
});

app.get('/api/endpoint1', (req, res) => {
    res.send(JSON.stringify({value: 1}));
})

app.get('/api/endpoint2', (req, res) => {
    // Set Content-Type differently for this particular API
    res.set({'Content-Type': 'application/xml'});
    res.send(`<note>
        <to>Tove</to>
        <from>Jani</from>
        <heading>Reminder</heading>
        <body>Don't forget me this weekend!</body>
        </note>`);
})

With SQL server you can just use a CTE instead of IF/THEN logic to make it easy to map from your existing queries and change the number of involved queries;

WITH cte AS (
    SELECT product,price,1 a FROM table1 WHERE project=1   UNION ALL
    SELECT product,price,2 a FROM table1 WHERE customer=2  UNION ALL
    SELECT product,price,3 a FROM table1 WHERE company=3
)
SELECT TOP 1 WITH TIES product,price FROM cte ORDER BY a;

An SQLfiddle to test with.

Alternately, you can combine it all into one SELECT to simplify it for the optimizer;

SELECT TOP 1 WITH TIES product,price FROM table1 
WHERE project=1 OR customer=2 OR company=3
ORDER BY CASE WHEN project=1  THEN 1 
              WHEN customer=2 THEN 2
              WHEN company=3  THEN 3 END;

Another SQLfiddle.

In javascript , the Date.getTimezoneOffset() method returns the time-zone offset from UTC, in minutes, for the current locale.

var x = new Date();
var currentTimeZoneOffsetInHours = x.getTimezoneOffset() / 60;

Moment'timezone will be a useful tool. http://momentjs.com/timezone/

Convert Dates Between Timezones

var newYork    = moment.tz("2014-06-01 12:00", "America/New_York");
var losAngeles = newYork.clone().tz("America/Los_Angeles");
var london     = newYork.clone().tz("Europe/London");

newYork.format();    // 2014-06-01T12:00:00-04:00
losAngeles.format(); // 2014-06-01T09:00:00-07:00
london.format();     // 2014-06-01T17:00:00+01:00

This is a simple solution which solved the problem for me:

label 
{

/* for firefox */
vertical-align:middle; 

/*for internet explorer */
*bottom:3px;
*position:relative; 

padding-bottom:7px; 

}

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.

$( this ).attr( 'checked', 'checked' )

just attr( 'checked' ) will return the value of $( this )'s checked attribute. To set it, you need that second argument. Based on <input type="checkbox" checked="checked" />

Edit:

Based on comments, a more appropriate manipulation would be:

$( this ).attr( 'checked', true )

And a straight javascript method, more appropriate and efficient:

this.checked = true;

Thanks @Andy E for that.

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.Integer;

you try to cast an Array of Object to cast into Array of Integer. You cant do it. This type of downcast is not permitted.

You can make an array of Integer, and after that copy every value of the first array into second array.

By default mongodb has no enabled access control, so there is no default user or password.

To enable access control, use either the command line option --auth or security.authorization configuration file setting.

You can use the following procedure or refer to Enabling Auth in the MongoDB docs.

Procedure

1. Start MongoDB without access control.

   mongod --port 27017 --dbpath /data/db1
   

2. Connect to the instance.

   mongo --port 27017
   

3. Create the user administrator.

   use admin
   db.createUser(
     {
       user: "myUserAdmin",
       pwd: "abc123",
       roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
     }
   )
   

4. Re-start the MongoDB instance with access control.

   mongod --auth --port 27017 --dbpath /data/db1
   

5. Authenticate as the user administrator.

   mongo --port 27017 -u "myUserAdmin" -p "abc123" \
     --authenticationDatabase "admin"
   

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

If you want to use hex codes, you should add -e option to enable interpretation of backslash escapes by echo (but the result is the same as with echoCtrlRCtrlB). And as wallyk said, you probably want to add -n to prevent the output of a newline:

echo -en '\x12\x02' > /dev/ttyS0

Also make sure that /dev/ttyS0 is the port you want.

All variables are cached so the loop and keyup event doesn't have to create a jQuery object everytime it runs.

var $input = $('input:text'),
    $register = $('#register');    
$register.attr('disabled', true);

$input.keyup(function() {
    var trigger = false;
    $input.each(function() {
        if (!$(this).val()) {
            trigger = true;
        }
    });
    trigger ? $register.attr('disabled', true) : $register.removeAttr('disabled');
});

Check working example at http://jsfiddle.net/DKNhx/3/

You should be able to use the format method:

"Location: {0:20} Revision {1}".format(Location,Revision)

You will have to figure out the of the format length for each line depending on the length of the label. The User line will need a wider format width than the Location or District lines.

Google will eventually block your IP when you exceed a certain amount of requests.

Normally it happens when the target is null. So better check the invoke target first then do the linq query.

Here the code to use your app.js

input specifies file name

res.download(__dirname+'/'+input);

Running git pull performs the following tasks, in order:

1. git fetch
2. git merge

The merge step combines branches that have been setup to be merged in your config. You want to undo the merge step, but probably not the fetch (doesn't make a lot of sense and shouldn't be necessary).

To undo the merge, use git reset --hard to reset the local repository to a previous state; use git-reflog to find the SHA-1 of the previous state and then reset to it.

Warning

The commands listed in this section remove all uncommitted changes, potentially leading to a loss of work:

git reset --hard

Alternatively, reset to a particular point in time, such as:

git reset --hard master@{"10 minutes ago"}

Taking Lea's demo, here's a different way of making unordered lists, with borders: http://jsfiddle.net/vX4K8/7/

If adding an extra column with the hyperlinks is not an option, the alternative is to use an external editor to enclose your hyperlink into =hyperlink(" and "), in order to obtain =hyperlink("originalCellContent")

If you have Notepad++, this is a recipe you can use to perform this operation semi-automatically:

• Copy the column of addresses to Notepad++
• Keeping ALT-SHIFT pressed, extended your cursor from the top left corner to the bottom left corner, and type =hyperlink(". This adds =hyperlink(" at the beginning of each entry.
• Open "Replace" menu (Ctrl-H), activate regular expressions (ALT-G), and replace $ (end of line) with "\). This adds a closed quote and a closed parenthesis (which needs to be escaped with \ when regular expressions are activated) at the end of each line.
• Paste back the data in Excel. In practice, just copy the data and select the first cell of the column where you want the data to end up.

It's worth to mention that CLOB / BLOB data types and their sizes are supported by MySQL 5.0+, so you can choose the proper data type for your need.

http://dev.mysql.com/doc/refman/5.7/en/storage-requirements.html

Data Type   Date Type   Storage Required
(CLOB)      (BLOB)

TINYTEXT    TINYBLOB    L + 1 bytes, where L < 2**8  (255)
TEXT        BLOB        L + 2 bytes, where L < 2**16 (64 K)
MEDIUMTEXT  MEDIUMBLOB  L + 3 bytes, where L < 2**24 (16 MB)
LONGTEXT    LONGBLOB    L + 4 bytes, where L < 2**32 (4 GB)

where L stands for the byte length of a string

You can try this command,

adb shell dumpsys activity recents

There you can find current activity name in activity stack.

To get most recent activity name:

adb shell dumpsys activity recents | find "Recent #0"

The file needs be writable by the camera, as Praveen pointed out.

In my usage I wanted to store the file in internal storage. I did this with:

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (i.resolveActivity(getPackageManager()!=null)){
    try{
        cacheFile = createTempFile("img",".jpg",getCacheDir());
        cacheFile.setWritavle(true,false);
    }catch(IOException e){}
    if(cacheFile != null){
        i.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(cacheFile));
        startActivityForResult(i,REQUEST_IMAGE_CAPTURE);
    }
}

Here cacheFile is a global file used to refer to the file which is written. Then in the result method the returned intent is null. Then the method for processing the intent looks like:

protected void onActivityResult(int requestCode,int resultCode,Intent data){
    if(requestCode != RESULT_OK){
        return;
    }
    if(requestCode == REQUEST_IMAGE_CAPTURE){
        try{
            File output = getImageFile();
            if(output != null && cacheFile != null){
                copyFile(cacheFile,output);

                //Process image file stored at output

                cacheFile.delete();
                cacheFile=null;
            }
        }catch(IOException e){}
    }
}

Here getImageFile() is a utility method to name and create the file in which the image should be stored, and copyFile() is a method to copy a file.

Byterbit solution is problematic because:

1. having the client control expiration of a server side cookie is a security issue.
2. if expiration timeout set on server side is smaller than the timeout set on client side, the page would not reflect the actual state of the cookie.
3. even if for the sake of comfort in development stage, this is a problem because it won't reflect the right behaviour (in timing) on release stage.

for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.

expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.

making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

One line solution

var id = request.Headers.GetValues("MyCustomID").FirstOrDefault();

Maybe a little late to the party but why don't you use sessions to store your data?

bookingfacilities.php

session_start();
$_SESSION['form_date'] = $date;

successfulbooking.php

session_start();
$date = $_SESSION['form_date']; 

Nobody will see this.

Because otherwise scanf will think you are passing a pointer to a float which is a smaller size than a double, and it will return an incorrect value.

I know this is old but I have come across this issue as well but found a fix for this that worked for me:

1. go to "Services"
2. under "Name" find your username
3. right click and select "Start"

Go to your MySQL workbench and select "Startup / Shutdown" under "INSTANCE" and you should be good to go. Hope this helps anyone that comes across this.

If you use IIS Express via Visual Studio instead of the builtin ASP.net host, you can achieve this.

Binding IIS Express to an IP Address

(The following comes from experience with VS2005.)

If you edit an ASPX page while debugging, then the codebehind doesn't get updated with the new classes. So, you have to stop debugging, trivially edit the ASPX page (like add a button or something), then click Design View, then delete the button. Then, your designer files should be updated.

If you are having a different issue with VS2008, then I can't help.

get-windowsfeature | where name -like RSAT-AD-PowerShell | Install-WindowsFeature

I personally prefer "" unless there is a good reason to something more complex.

this will also work

data.groupby(data['date'].dt.year)

This works for me in PowerShell:

docker run --rm -v ${PWD}:/data alpine ls /data

TextWatcher didn't work for me as it kept firing for every EditText and messing up each others values.

Here is my solution:

public class ConsultantTSView extends Activity {
    .....

    //Submit is called when I push submit button.
    //I wanted to retrieve all EditText(tsHours) values in my HoursList

    public void submit(View view){

        ListView TSDateListView = (ListView) findViewById(R.id.hoursList);
        String value = ((EditText) TSDateListView.getChildAt(0).findViewById(R.id.tsHours)).getText().toString();
    }
}

Hence by using the getChildAt(xx) method you can retrieve any item in the ListView and get the individual item using findViewById. And it will then give the most recent value.

Another problem is that CSS has to be defined outside component scope, breaking component encapsulation

This is not true. With scss (SASS) you can easily style the component (itself;host) as so:

:host {
    display: block;
    position: absolute;
    width: 100%;
    height: 100%;
    pointer-events: none;
    visibility: hidden;

    &.someClass {
        visibility: visible;
    }
}

This way the encapsulation is "unbroken".

I also underwent the same issue as Maven doesn't create the settings.xml file under .m2 folder. What I did was the following and it works smoothly without any issues.

Go to the location where you maven was unzipped.

Direct to following path,

\apache-maven-3.0.4\conf\ and copy the settings.xml file and paste it inside your .m2 folder.

Now create a maven project.

This code will print an asterisk instead of every letter.

import sys
import msvcrt

passwor = ''
while True:
    x = msvcrt.getch()
    if x == '\r':
        break
    sys.stdout.write('*')
    passwor +=x

print '\n'+passwor

Use the replace() method on string:

>>> stuff = "Big and small"
>>> stuff.replace( " and ", "/" )
'Big/small'

Whilst, as has been pointed out, it is possible to see the current default socket buffer sizes in /proc, it is also possible to check them using sysctl (Note: Whilst the name includes ipv4 these sizes also apply to ipv6 sockets - the ipv6 tcp_v6_init_sock() code just calls the ipv4 tcp_init_sock() function):

 sysctl net.ipv4.tcp_rmem
 sysctl net.ipv4.tcp_wmem

However, the default socket buffers are just set when the sock is initialised but the kernel then dynamically sizes them (unless set using setsockopt() with SO_SNDBUF). The actual size of the buffers for currently open sockets may be inspected using the ss command (part of the iproute package), which can also provide a bunch more info on sockets like congestion control parameter etc. E.g. To list the currently open TCP (t option) sockets and associated memory (m) information:

ss -tm

Here's some example output:

State       Recv-Q Send-Q        Local Address:Port        Peer Address:Port
ESTAB       0      0             192.168.56.102:ssh        192.168.56.1:56328
skmem:(r0,rb369280,t0,tb87040,f0,w0,o0,bl0,d0)

Here's a brief explanation of skmem (socket memory) - for more info you'll need to look at the kernel sources (e.g. sock.h):

r:sk_rmem_alloc
rb:sk_rcvbuf          # current receive buffer size
t:sk_wmem_alloc
tb:sk_sndbuf          # current transmit buffer size
f:sk_forward_alloc
w:sk_wmem_queued      # persistent transmit queue size
o:sk_omem_alloc
bl:sk_backlog
d:sk_drops

In my case, it was the missing trailing slash in the url. Adding the trailing slash solved my problem.

Here's an approach that could resolve your problem, and if not would help with troubleshooting.

1. Create a second Apache virtual server identical to the current one

2. Send all "normal" user traffic to the original virtual server

3. Send special or long-running traffic to the new virtual server

Special or long-running traffic could be report-generation, maintenance ops or anything else you don't expect to complete in <<1 second. This can happen serving APIs, not just web pages.

If your resource utilization is low but you still exceed MaxClients, the most likely answer is you have new connections arriving faster than they can be serviced. Putting any slow operations on a second virtual server will help prove if this is the case. Use the Apache access logs to quantify the effect.

Assuming you want all "overlapping" time periods, i.e. all that have at least one day in common.

Try to envision time periods on a straight time line and move them around before your eyes and you will see the necessary conditions.

SELECT *
FROM   tbl
WHERE  start_date <= '2012-04-12'::date
AND    end_date   >= '2012-01-01'::date;

This is sometimes faster for me than OVERLAPS - which is the other good way to do it (as @Marco already provided).

Note the subtle difference (per documentation):

OVERLAPS automatically takes the earlier value of the pair as the start. Each time period is considered to represent the half-open interval start <= time < end, unless start and end are equal in which case it represents that single time instant. This means for instance that two time periods with only an endpoint in common do not overlap.

Bold emphasis mine.

Performance

For big tables the right index can help performance (a lot).

CREATE INDEX tbl_date_inverse_idx ON tbl(start_date, end_date DESC);

Possibly with another (leading) index column if you have additional selective conditions.

Note the inverse order of the two columns. Detailed explanation:

• Optimizing queries on a range of timestamps (two columns)

I want to delete my sqlite db from document directory.I delete the sqlite db successfully by below answer

NSString *strFileName = @"sqlite";
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSArray *contents = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:NULL];
NSEnumerator *enumerator = [contents objectEnumerator];
NSString *filename;
while ((filename = [enumerator nextObject])) {
    NSLog(@"The file name is - %@",[filename pathExtension]);
    if ([[filename pathExtension] isEqualToString:strFileName]) {
       [fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL];
        NSLog(@"The sqlite is deleted successfully");
    }
}

Per Steven C. Howell's comment on Mark Rushakoff's answer

j = (i + 1) / n
stdout.write('\r')
stdout.write('[%-20s] %d%%' % ('='*int(20*j), 100*j))
stdout.flush()

where i is the current item and n is the total number of items

For me above solutions didn't work then I tried

map.setCenter(new google.maps.LatLng(lat, lng));

and it worked as expected.

In iOS development NIB loading is a little bit different from Mac development.

In Mac development an IBOutlet is usually a weak reference: if you have a subclass of NSViewController only the top-level view will be retained and when you dealloc the controller all its subviews and outlets are freed automatically.

UiViewController use Key Value Coding to set the outlets using strong references. So when you dealloc your UIViewController, the top view will automatically deallocated, but you must also deallocate all its outlets in the dealloc method.

In this post from the Big Nerd Ranch, they cover this topic and also explain why using a strong reference in IBOutlet is not a good choice (even if it is recommended by Apple in this case).

You have to disable the sandbox for Groovy in your job configuration.

Currently this is not possible for multibranch projects where the groovy script comes from the scm. For more information see https://issues.jenkins-ci.org/browse/JENKINS-28178

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

Yeah that's it without no further issues, to avoid raw string json this is it.

    public ActionResult GetJson()
    {
        var json = System.IO.File.ReadAllText(
            Server.MapPath(@"~/App_Data/content.json"));

        return new ContentResult
        {
            Content = json,
            ContentType = "application/json",
            ContentEncoding = Encoding.UTF8
        };
    } 

NOTE: please note that method return type of JsonResult is not working for me, since JsonResult and ContentResult both inherit ActionResult but there is no relationship between them.

The new version 2.4 of Apache HTTP Server has a module called mod_proxy_wstunnel which is a websocket proxy.

http://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html

In addition to the above, and just to point out the bleedin' obvious...

To many this is hyper obvious, but to someone used to writing apps which are just run and then end: a servlet spends most of its time hanging around doing nothing... waiting to be sent something, a request, and then responding to it. For this reason a servlet has a lifetime: it is initalised and then waits around, responding to anything thrown at it, and is then destroyed. Which implies that it has to be created (and later destroyed) by something else (a framework), that it runs in its own thread or process, and that it does nothing unless asked to. And also that, by some means or other, a mechanism must be implemented whereby this "entity" can "listen" for requests.

I suggest that reading about threads, processes and sockets will throw some light on this: it's quite different to the way a basic "hello world" app functions.

It could be argued that the term "server" or "servlet" is a bit of an overkill. A more rational and simpler name might be "responder". The reason for the choice of the term "server" is historical: the first such arrangements were "file servers", where multiple user/client terminals would ask for a specific file from a central machine, and this file would then be "served up" like a book or a plate of fish and chips.

If you want to join the selected lines (you are in visual mode), then just press gJ to join your lines with no spaces whatsoever.

Most of the answers dont include the results of ALL promises individually, so in case someone is looking for this particular behaviour, this is a possible solution using recursion.

It follows the style of Promise.all:

• Returns the array of results in the .then() callback.

• If some promise fails, its returned immediately in the .catch() callback.

const promiseEach = (arrayOfTasks) => {_x000D_
  let results = []_x000D_
  return new Promise((resolve, reject) => {_x000D_
    const resolveNext = (arrayOfTasks) => {_x000D_
      // If all tasks are already resolved, return the final array of results_x000D_
      if (arrayOfTasks.length === 0) return resolve(results)_x000D_
_x000D_
      // Extract first promise and solve it_x000D_
      const first = arrayOfTasks.shift()_x000D_
_x000D_
      first().then((res) => {_x000D_
        results.push(res)_x000D_
        resolveNext(arrayOfTasks)_x000D_
      }).catch((err) => {_x000D_
        reject(err)_x000D_
      })_x000D_
    }_x000D_
    resolveNext(arrayOfTasks)_x000D_
  })_x000D_
}_x000D_
_x000D_
// Lets try it _x000D_
_x000D_
const promise = (time, shouldThrowError) => new Promise((resolve, reject) => {_x000D_
  const timeInMs = time * 1000_x000D_
  setTimeout(()=>{_x000D_
    console.log(`Waited ${time} secs`)_x000D_
    if (shouldThrowError) reject(new Error('Promise failed'))_x000D_
    resolve(time)_x000D_
  }, timeInMs)_x000D_
})_x000D_
_x000D_
const tasks = [() => promise(1), () => promise(2)]_x000D_
_x000D_
promiseEach(tasks)_x000D_
  .then((res) => {_x000D_
    console.log(res) // [1, 2]_x000D_
  })_x000D_
  // Oops some promise failed_x000D_
  .catch((error) => {_x000D_
    console.log(error)_x000D_
  })

Note about the tasks array declaration:

In this case is not possible to use the following notation like Promise.all would use:

const tasks = [promise(1), promise(2)]

And we have to use:

const tasks = [() => promise(1), () => promise(2)]

The reason is that JavaScript starts executing the promise immediatelly after its declared. If we use methods like Promise.all, it just checks that the state of all of them is fulfilled or rejected, but doesnt start the exection itself. Using () => promise() we stop the execution until its called.

I have solved this issue about $ sudo docker run hello-world following the Docker doc.

If you are behind an HTTP Proxy server of corporate, this may solve your problem.

Docker doc also displays other situation about HTTP proxy setting.

ffmpeg -i infile.mp4 -i infile.srt -c copy -c:s mov_text outfile.mp4

-vf subtitles=infile.srt will not work with -c copy

The order of -c copy -c:s mov_text is important. You are telling FFmpeg:

1. Video: copy, Audio: copy, Subtitle: copy
2. Subtitle: mov_text

If you reverse them, you are telling FFmpeg:

1. Subtitle: mov_text
2. Video: copy, Audio: copy, Subtitle: copy

Alternatively you could just use -c:v copy -c:a copy -c:s mov_text in any order.

Ok uninstall the app, but we admit that the data not must be lost? This can be resolve, upgrading versionCode and versionName and try the application in "Release" mode.

For example, this is important when we want to try the migration of our Database. We can compare the our application on play store with actual application not release yet.

If you are using wamp you can try this. Just type use your_Database_name first.

1. Click your wamp server icon then look for MYSQL > MSQL Console then run it.

2. If you dont have password, just hit enter and type :

   mysql> use database_name;
   mysql> source location_of_your_file;
   

   If you have password, you will promt to enter a password. Enter you password first then type:

   mysql> use database_name;
   mysql> source location_of_your_file;
   

location_of_your_file should look like C:\mydb.sql

so the commend is mysql>source C:\mydb.sql;

This kind of importing sql dump is very helpful for BIG SQL FILE.

I copied my file mydb.sq to directory C: .It should be capital C: in order to run

and that's it.

"AND" does not work in my PHP code.

Server's version maybe?

"&&" works fine.

Somewhat cleaner solution than the accepted answer (based on this question):

public static boolean isAppInstalled(Context context, String packageName) {
    try {
        context.getPackageManager().getApplicationInfo(packageName, 0);
        return true;
    }
    catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

I chose to put it in a helper class as a static utility. Usage example:

boolean whatsappFound = AndroidUtils.isAppInstalled(context, "com.whatsapp");

This answer shows how to get the app from the Play Store if the app is missing, though care needs to be taken on devices that don't have the Play Store.

To avoid having "pod install" reset only_active_arch for debug each time it's run, you can add the following to your pod file

# Append to your Podfile
post_install do |installer_representation|
    installer_representation.project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
        end
    end
end

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

If you declare your callback as mentioned by @lex82 like

callback = "callback(item.id, arg2)"

You can call the callback method in the directive scope with object map and it would do the binding correctly. Like

scope.callback({arg2:"some value"});

without requiring for $parse. See my fiddle(console log) http://jsfiddle.net/k7czc/2/

Update: There is a small example of this in the documentation:

& or &attr - provides a way to execute an expression in the context of the parent scope. If no attr name is specified then the attribute name is assumed to be the same as the local name. Given and widget definition of scope: { localFn:'&myAttr' }, then isolate scope property localFn will point to a function wrapper for the count = count + value expression. Often it's desirable to pass data from the isolated scope via an expression and to the parent scope, this can be done by passing a map of local variable names and values into the expression wrapper fn. For example, if the expression is increment(amount) then we can specify the amount value by calling the localFn as localFn({amount: 22}).

In case someone wants to make use of sorting at a critical part of their programs here's a performance comparison for the different proposals:

import numpy as np
table = np.random.rand(5000, 10)

%timeit table.view('f8,f8,f8,f8,f8,f8,f8,f8,f8,f8').sort(order=['f9'], axis=0)
1000 loops, best of 3: 1.88 ms per loop

%timeit table[table[:,9].argsort()]
10000 loops, best of 3: 180 µs per loop

import pandas as pd
df = pd.DataFrame(table)
%timeit df.sort_values(9, ascending=True)
1000 loops, best of 3: 400 µs per loop

So, it looks like indexing with argsort is the quickest method so far...

I typically make this function apart of all my projects. Quick and easy.

unfactorize <- function(df){
  for(i in which(sapply(df, class) == "factor")) df[[i]] = as.character(df[[i]])
  return(df)
}

Please check this answer

// In angularJS script
$scope.foo = function() {
    console.log('test');
};
$window.angFoo = function() {
    $scope.foo();
    $scope.$apply(); 
};
    
// In jQuery
if (window.angFoo) {
    window.angFoo();
}

Using this fiddle, you can play around with the width of each div. I've tried in both Chrome and IE and I notice a difference in width between 33% and 33.3%. I also notice a very small difference between 33.3% and 33.33%. I don't notice any difference further than this.

The difference between 33.33% and the theoretical 33.333...% is a mere 0.00333...%.

For arguments sake, say my screen width is 1960px; a fairly high but common resolution. The difference between these two widths is still only 0.065333...px.

So, further than two decimal places, the difference in precision is negligible.

Easy peasy. Your data frame will look like this:

df <- data.frame(sex=c('M','F','M'),
                 occupation=c('Student','Analyst','Analyst'))

You can then do the equivalent of a COUNTIF by first specifying the IF part, like so:

df$sex == 'M'

This will give you a boolean vector, i.e. a vector of TRUE and FALSE. What you want is to count the observations for which the condition is TRUE. Since in R TRUE and FALSE double as 1 and 0 you can simply sum() over the boolean vector. The equivalent of COUNTIF(sex='M') is therefore

sum(df$sex == 'M')

Should there be rows in which the sex is not specified the above will give back NA. In that case, if you just want to ignore the missing observations use

sum(df$sex == 'M', na.rm=TRUE)

The complete example with an array. Replace "constructArrayType()" by "constructCollectionType()" or any other type you need.

Angular Concepts

• imports makes the exported declarations of other modules available in the current module
• declarations are to make directives (including components and pipes) from the current module available to other directives in the current module. Selectors of directives, components or pipes are only matched against the HTML if they are declared or imported.
• providers are to make services and values known to DI (dependency injection). They are added to the root scope and they are injected to other services or directives that have them as dependency.

A special case for providers are lazy loaded modules that get their own child injector. providers of a lazy loaded module are only provided to this lazy loaded module by default (not the whole application as it is with other modules).

For more details about modules see also https://angular.io/docs/ts/latest/guide/ngmodule.html

• exports makes the components, directives, and pipes available in modules that add this module to imports. exports can also be used to re-export modules such as CommonModule and FormsModule, which is often done in shared modules.

• entryComponents registers components for offline compilation so that they can be used with ViewContainerRef.createComponent(). Components used in router configurations are added implicitly.

TypeScript (ES2015) imports

import ... from 'foo/bar' (which may resolve to an index.ts) are for TypeScript imports. You need these whenever you use an identifier in a typescript file that is declared in another typescript file.

Angular's @NgModule() imports and TypeScript import are entirely different concepts.

See also jDriven - TypeScript and ES6 import syntax

Most of them are actually plain ECMAScript 2015 (ES6) module syntax that TypeScript uses as well.

In the case of stored procedure update, you should delete it from the .dbml file and reinsert it again. But if the stored procedure have two paths (ex: if something; display some columns; else display some other columns), make sure the two paths have the same columns aliases!!! Otherwise only the first path columns will exist.

To add to this answer. I just found out that it will also break down if you use a hyphen in your form name (Angular 1.3):

So this will not work:

<form name="my-form">
    <input name="myText" type="text" ng-model="mytext" required />
    <button ng-disabled="my-form.$invalid">Save</button>
</form>

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.

With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:

|--------|-------------------|
| P(dBm) |        P(mW)      |
|--------|-------------------|
|    50  |  100000           |    
|    40  |   10000           |    strong transmitter
|    30  |    1000           |             ^  
|    20  |     100           |             |
|    10  |      10           |             |
|     0  |       1           |
|   -10  |       0.1         |
|   -20  |       0.01        |
|   -30  |       0.001       |
|   -40  |       0.0001      |
|   -50  |       0.00001     |             |
|   -60  |       0.000001    |             |
|   -70  |       0.0000001   |             v
|   -80  |       0.00000001  |    sensitive receiver
|   -90  |       0.000000001 |
|--------|-------------------|

When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.

When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.

Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

The following should work with the latest version of Apache common codec

byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes));

and for encoding

byte[] encodedBytes = Base64.getEncoder().encode(decodedBytes);
System.out.println(new String(encodedBytes));

You just need to 'capture' the bit between the brackets.

\[(.*?)\]

To capture you put it inside parentheses. You do not say which language this is using. In Perl for example, you would access this using the $1 variable.

my $string ='This is the match [more or less]';
$string =~ /\[(.*?)\]/;
print "match:$1\n";

Other languages will have different mechanisms. C#, for example, uses the Match collection class, I believe.

try this

public void setUpTableData() {
    DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();

    /**
    * additional code.
    **/
    tableModel.setRowCount(0);
    /**/
    ArrayList<Contact> list = new ArrayList<Contact>();
    if (!con.equals(""))
        list = sql.getContactListsByGroup(con);
    else
        list = sql.getContactLists();
    for (int i = 0; i < list.size(); i++) {
        String[] data = new String[7];

        data[0] = list.get(i).getName();
        data[1] = list.get(i).getEmail();
        data[2] = list.get(i).getPhone1();
        data[3] = list.get(i).getPhone2();
        data[4] = list.get(i).getGroup();
        data[5] = list.get(i).getId();

        tableModel.addRow(data);
    }
    jTable.setModel(tableModel);
    /**
    * additional code.
    **/
    tableModel.fireTableDataChanged();
    /**/
}

It's odd how many incorrect answers has been given to asynchronous case! It can be simply shown that checking index does not provide expected behavior:

// INCORRECT
var list = [4000, 2000];
list.forEach(function(l, index) {
    console.log(l + ' started ...');
    setTimeout(function() {
        console.log(index + ': ' + l);
    }, l);
});

output:

4000 started
2000 started
1: 2000
0: 4000

If we check for index === array.length - 1, callback will be called upon completion of first iteration, whilst first element is still pending!

To solve this problem without using external libraries such as async, I think your best bet is to save length of list and decrement if after each iteration. Since there's just one thread we're sure there no chance of race condition.

var list = [4000, 2000];
var counter = list.length;
list.forEach(function(l, index) {
    console.log(l + ' started ...');
    setTimeout(function() {
        console.log(index + ': ' + l);
        counter -= 1;
        if ( counter === 0)
            // call your callback here
    }, l);
});

git reset --hard will force the working directory back to the last commit and delete new/changed files.

 txtText.Font = new Font("Segoe UI", 8,FontStyle.Bold);
 //Font(Font Name,Font Size,Font.Style)

$(document).ready(function() {
  $(':checkbox').click(function() {
    var cObj = $(this);
    var cVal = cObj.val();
    var tObj = $('#t');
    var tVal = tObj.val();
    if (cObj.attr("checked")) {
      tVal = tVal + "," + cVal;
      $('#t').attr("value", tVal);
    } else {
      //TODO remove unchecked value.
    }
  });
});

With a mediaquery based on a min-width you could achieve something like http://jsbin.com/aruyiq/1/edit

CSS

.wrapper { 
  border : 2px dotted #ccc; padding: 2px; 
}

.wrapper div {
   width: 100%; 
   min-height: 200px;
   padding: 10px;
   -webkit-box-sizing: border-box;
   -moz-box-sizing: border-box;
   box-sizing: border-box;
}
#one { background-color: gray; }
#two { background-color: white; }

@media screen and (min-width: 600px) {
   .wrapper {
      height: auto; overflow: hidden; // clearing 
   }
   #one { width: 200px; float: left; }
   #two { margin-left: 200px; }
}

In my example the breakpoint is 600px but you could adapt it to your needs.

exec

executes a command and never returns. It's like a return statement in a function.

If the command is not found exec returns false. It never returns true, because if the command is found it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

system

executes a command and your Perl script is continued after the command has finished.

The return value is the exit status of the command. You can find documentation about it in perlfunc.

backticks

like system executes a command and your perl script is continued after the command has finished.

In contrary to system the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and execit is an operator.

Other ways

What is missing from the above is a way to execute a command asynchronously. That means your perl script and your command run simultaneously. This can be accomplished with open. It allows you to read STDOUT/STDERR and write to STDIN of your command. It is platform dependent though.

There are also several modules which can ease this tasks. There is IPC::Open2 and IPC::Open3 and IPC::Run, as well as Win32::Process::Create if you are on windows.

Apache commons provides utility to convert the stack trace from throwable to string.

Usage:

ExceptionUtils.getStackTrace(e)

Just use MS Web platform Installer 4.5 to install all stuff for MS SQL Server 2008 R2.

And don't forget to reload machine.

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

SELECT ROUTINE_TYPE, ROUTINE_NAME, ROUTINE_DEFINITION
FROM INFORMATION_SCHEMA.ROUTINES 
WHERE ROUTINE_DEFINITION LIKE '%Your Text%' 

The Newest MySQL Versions have the new BIT data type in which you can specify the number of bits in the field, for example BIT(1) to use as Boolean type, because it can be only 0 or 1.

If I google for "Unable to convert MySQL date/time value to System.DateTime" I see numerous references to a problem accessing MySQL from Visual Studio. Is that your context?

One solution suggested is:

This is not a bug but expected behavior. Please check manual under connect options and set "Allow Zero Datetime" to true, as on attached pictures, and the error will go away.

None of the above solutions alone worked for me. On Windows 7 this worked:

Install Rapid Environment Editor and remove any entries for node, npm, angular-cli or @angular/cli

Uninstall node.js and reinstall. Run Rapid Environment Editor again and make sure node.js and npm are in your System or User path. Uninstall any existing ng versions with:

npm uninstall -g angular-cli

npm uninstall -g @angular/cli

npm cache clean

Delete the C:\Users\YOU\AppData\Roaming\npm\node_modules\@angular folder.

Reboot, then, finally, run:

npm install -g @angular/cli

Then hold your breath and run ng -v. If you're lucky, you'll get some love. Hold your breath henceforward every time you run the ng command, because 'command not found' has magically reappeared for me several times after ng was running fine and I thought the problem was solved.
