I think the following code will help....

public void btnShareClick(View v) {
    // shareBtnFlag = 1;
    Dialog d = new Dialog(DrawAppActivity.this);
    d.requestWindowFeature(d.getWindow().FEATURE_NO_TITLE);
    d.setCancelable(true);

    d.setContentView(R.layout.sharing);

    final Button btnFacebook = (Button) d.findViewById(R.id.btnFacebook);
    final Button btnEmail = (Button) d.findViewById(R.id.btnEmail);

    btnEmail.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            if (!btnEmail.isSelected()) {
                btnEmail.setSelected(true);
            } else {
                btnEmail.setSelected(false);
            }
            saveBtnFlag = 1;
            // Check if email id is available-------------

For facebook application use facebook SDK

It gets serialized so that the URI can read the name value pairs in the POST request by default. You could try setting processData:false to your list of params. Not sure if that would help.

You may simply read the stream of a file

using (var target = new MemoryStream())
{
    postedFile.InputStream.CopyTo(target);
    var array = target.ToArray();
}

First 5/6 indexes will tell you the file type. In case of FLV its 70, 76, 86, 1, 5.

private static readonly byte[] FLV = { 70, 76, 86, 1, 5};

bool isAllowed = array.Take(5).SequenceEqual(FLV);

if isAllowed equals true then its FLV.

OR

Read the content of a file

var contentArray = target.GetBuffer();
var content = Encoding.ASCII.GetString(contentArray);

First two/three letters will tell you the file type.
In case of FLV its "FLV......"

content.StartsWith("FLV")

I had the same problem, when I was trying to switch "C:\superfolder"

Error messages:

Directory 'C:\superfolder\subfolder\.svn'
containing
working copy admin area is missing
Please execute the 'Cleanup' command.

After trying to do a "cleanup", I got the following error:

 Cleanup failed to process the following paths:
 C:\superfolder\
'C:\superfolder\subfolder\' is not a working copy directory

Solution:

1. Delete the folder "subfolder"
2. Clean up the folder "superfolder"
3. Try to switch again the folder "superfolder"

this worked for me. Please let me know if it also works for you.

Neither code is always better. They do different things, so they are good at different things.

InvariantCultureIgnoreCase uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.

OrdinalIgnoreCase compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é or ö. This is also faster because there are no extra rules to apply before comparing.

this php function explode string by newline

Attention : new line in Windows is \r\n and in Linux and Unix is \n
this function change all new lines to linux mode then split it.
pay attention that empty lines will be ignored

function splitNewLine($text) {
    $code=preg_replace('/\n$/','',preg_replace('/^\n/','',preg_replace('/[\r\n]+/',"\n",$text)));
    return explode("\n",$code);
}

example

$a="\r\n\r\n\n\n\r\rsalam\r\nman khobam\rto chi\n\rche khabar\n\r\n\n\r\r\n\nbashe baba raftam\r\n\r\n\r\n\r\n";
print_r( splitNewLine($a) );

output

Array
(
    [0] => salam
    [1] => man khobam
    [2] => to chi
    [3] => che khabar
    [4] => bashe baba raftam
)

This will make the scroll bars always display when there is content within windows that must be scrolled to access, it applies to all windows and all apps on the Mac:

Generally, the system should be handling view controller instantiation with a storyboard. What you want is to traverse the viewController hierarchy by grabbing a reference to the self.window.rootViewController as opposed to initializing view controllers, which should already be initialized correctly if you've setup your storyboard properly.

So, let's say your rootViewController is a UINavigationController and then you want to send something to its top view controller, you would do it like this in your AppDelegate's didFinishLaunchingWithOptions:

UINavigationController *nav = (UINavigationController *) self.window.rootViewController;
MyViewController *myVC = (MyViewController *)nav.topViewController;
myVC.data = self.data;

In Swift if would be very similar:

let nav = self.window.rootViewController as! UINavigationController;
let myVC = nav.topViewController as! MyViewController
myVc.data = self.data

You really shouldn't be initializing view controllers using storyboard id's from the app delegate unless you want to bypass the normal way storyboard is loaded and load the whole storyboard yourself. If you're having to initialize scenes from the AppDelegate you're most likely doing something wrong. I mean imagine you, for some reason, want to send data to a view controller way down the stack, the AppDelegate shouldn't be reaching way into the view controller stack to set data. That's not its business. It's business is the rootViewController. Let the rootViewController handle its own children! So, if I were bypassing the normal storyboard loading process by the system by removing references to it in the info.plist file, I would at most instantiate the rootViewController using instantiateViewControllerWithIdentifier:, and possibly its root if it is a container, like a UINavigationController. What you want to avoid is instantiating view controllers that have already been instantiated by the storyboard. This is a problem I see a lot. In short, I disagree with the accepted answer. It is incorrect unless the posters means to remove loading of the storyboard from the info.plist since you will have loaded 2 storyboards otherwise, which makes no sense. It's probably not a memory leak because the system initialized the root scene and assigned it to the window, but then you came along and instantiated it again and assigned it again. Your app is off to a pretty bad start!

This error can be caused by trying to end a response more than once. As other answers already mentioned, there are various methods that will end a response (like Response.End, or Response.Redirect). If you call more than one in a row, you'll get this error.

I came across this error when I tried to use Response.End after using Response.TransmitFile which seems to end the response too.

curl -X PUT -T "/path/to/file" "http://myputserver.com/puturl.tmp"

In a JFrame or JDialog you can always overwrite the setVisible() method, it works well. I haven't tried in a JPanel, but can be an alternative.

@Override
public void setVisible(boolean value) {
    super.setVisible(value);
    control.requestFocusInWindow();
}

I have come to the conclusion that this is not possible without any plugins.

With Swift 5.2 and iOS 13.4, according to your needs, you can use one of the following examples to align your VStack with top leading constraints and a full size frame.

Note that the code snippets below all result in the same display, but do not guarantee the effective frame of the VStack nor the number of View elements that might appear while debugging the view hierarchy.

1. Using frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:) method

The simplest approach is to set the frame of your VStack with maximum width and height and also pass the required alignment in frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:):

struct ContentView: View {

    var body: some View {
        VStack(alignment: .leading) {
            Text("Title")
                .font(.title)
            Text("Content")
                .font(.body)
        }
        .frame(
            maxWidth: .infinity,
            maxHeight: .infinity,
            alignment: .topLeading
        )
        .background(Color.red)
    }

}

As an alternative, if setting maximum frame with specific alignment for your Views is a common pattern in your code base, you can create an extension method on View for it:

extension View {

    func fullSize(alignment: Alignment = .center) -> some View {
        self.frame(
            maxWidth: .infinity,
            maxHeight: .infinity,
            alignment: alignment
        )
    }

}

struct ContentView : View {

    var body: some View {
        VStack(alignment: .leading) {
            Text("Title")
                .font(.title)
            Text("Content")
                .font(.body)
        }
        .fullSize(alignment: .topLeading)
        .background(Color.red)
    }

}

2. Using Spacers to force alignment

You can embed your VStack inside a full size HStack and use trailing and bottom Spacers to force your VStack top leading alignment:

struct ContentView: View {

    var body: some View {
        HStack {
            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)

                Spacer() // VStack bottom spacer
            }

            Spacer() // HStack trailing spacer
        }
        .frame(
            maxWidth: .infinity,
            maxHeight: .infinity
        )
        .background(Color.red)
    }

}

3. Using a ZStack and a full size background View

This example shows how to embed your VStack inside a ZStack that has a top leading alignment. Note how the Color view is used to set maximum width and height:

struct ContentView: View {

    var body: some View {
        ZStack(alignment: .topLeading) {
            Color.red
                .frame(maxWidth: .infinity, maxHeight: .infinity)

            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)
            }
        }
    }

}

4. Using GeometryReader

GeometryReader has the following declaration:

A container view that defines its content as a function of its own size and coordinate space. [...] This view returns a flexible preferred size to its parent layout.

The code snippet below shows how to use GeometryReader to align your VStack with top leading constraints and a full size frame:

struct ContentView : View {

    var body: some View {
        GeometryReader { geometryProxy in
            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)
            }
            .frame(
                width: geometryProxy.size.width,
                height: geometryProxy.size.height,
                alignment: .topLeading
            )
        }
        .background(Color.red)
    }

}

5. Using overlay(_:alignment:) method

If you want to align your VStack with top leading constraints on top of an existing full size View, you can use overlay(_:alignment:) method:

struct ContentView: View {

    var body: some View {
        Color.red

Solution without external packages

to perform a GET request using the fetch api I worked on this solution that doesn't require the installation of packages.

this is an example of a call to the google's map api

// encode to scape spaces
const esc = encodeURIComponent;
const url = 'https://maps.googleapis.com/maps/api/geocode/json?';
const params = { 
    key: "asdkfñlaskdGE",
    address: "evergreen avenue",
    city: "New York"
};
// this line takes the params object and builds the query string
const query = Object.keys(params).map(k => `${esc(k)}=${esc(params[k])}`).join('&')
const res = await fetch(url+query);
const googleResponse = await res.json()

feel free to copy this code and paste it on the console to see how it works!!

the generated url is something like:

https://maps.googleapis.com/maps/api/geocode/json?key=asdkf%C3%B1laskdGE&address=evergreen%20avenue&city=New%20York

this is what I was looking before I decided to write this, enjoy :D

<?php
    $res = mysql_query('SELECT getTreeNodeName(1) AS result');
    if ($res === false) {
        echo mysql_errno().': '.mysql_error();
    }
    while ($obj = mysql_fetch_object($res)) {
        echo $obj->result;
    }

Your Activity should have the method getResources. Do:

Drawable myIcon = getResources().getDrawable( R.drawable.icon );

As of API version 21 this method is deprecated and can be replaced with:

Drawable myIcon = AppCompatResources.getDrawable(context, R.drawable.icon);

If you need to specify a custom theme, the following will apply it, but only if API is version 21 or greater:

Drawable myIcon =  ResourcesCompat.getDrawable(getResources(), R.drawable.icon, theme);

I solved a problem to comparing a integer Column x a varchar column with

where CAST(Column_name AS CHAR CHARACTER SET latin1 ) collate latin1_general_ci = varchar_column_name

Without VBA macro, you can use this tips to get the username from the path :

=MID(INFO("DIRECTORY"),10,LEN(INFO("DIRECTORY"))-LEN(MID(INFO("DIRECTORY"),FIND("\",INFO("DIRECTORY"),10),1000))-LEN("C:\Users\"))

The character is a backslash \

From the bash manual:

The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date d = dateFormat.parse(datestring)

This is done with

ANALYZE TABLE table_name;

Read more about it here.

ANALYZE TABLE analyzes and stores the key distribution for a table. During the analysis, the table is locked with a read lock for MyISAM, BDB, and InnoDB. This statement works with MyISAM, BDB, InnoDB, and NDB tables.

Use //NOSONAR on the line you get warning if it is something you cannot help your code with. It works!

following are ways to access your different directories:-

./ = Your current directory
../ = One directory lower
../../ = Two directories lower
../../../ = Three directories lower

Python's built-in itertools module actually has a groupby function , but for that the elements to be grouped must first be sorted such that the elements to be grouped are contiguous in the list:

from operator import itemgetter
sortkeyfn = itemgetter(1)
input = [('11013331', 'KAT'), ('9085267', 'NOT'), ('5238761', 'ETH'), 
 ('5349618', 'ETH'), ('11788544', 'NOT'), ('962142', 'ETH'), ('7795297', 'ETH'), 
 ('7341464', 'ETH'), ('9843236', 'KAT'), ('5594916', 'ETH'), ('1550003', 'ETH')] 
input.sort(key=sortkeyfn)

Now input looks like:

[('5238761', 'ETH'), ('5349618', 'ETH'), ('962142', 'ETH'), ('7795297', 'ETH'),
 ('7341464', 'ETH'), ('5594916', 'ETH'), ('1550003', 'ETH'), ('11013331', 'KAT'),
 ('9843236', 'KAT'), ('9085267', 'NOT'), ('11788544', 'NOT')]

groupby returns a sequence of 2-tuples, of the form (key, values_iterator). What we want is to turn this into a list of dicts where the 'type' is the key, and 'items' is a list of the 0'th elements of the tuples returned by the values_iterator. Like this:

from itertools import groupby
result = []
for key,valuesiter in groupby(input, key=sortkeyfn):
    result.append(dict(type=key, items=list(v[0] for v in valuesiter)))

Now result contains your desired dict, as stated in your question.

You might consider, though, just making a single dict out of this, keyed by type, and each value containing the list of values. In your current form, to find the values for a particular type, you'll have to iterate over the list to find the dict containing the matching 'type' key, and then get the 'items' element from it. If you use a single dict instead of a list of 1-item dicts, you can find the items for a particular type with a single keyed lookup into the master dict. Using groupby, this would look like:

result = {}
for key,valuesiter in groupby(input, key=sortkeyfn):
    result[key] = list(v[0] for v in valuesiter)

result now contains this dict (this is similar to the intermediate res defaultdict in @KennyTM's answer):

{'NOT': ['9085267', '11788544'], 
 'ETH': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 
 'KAT': ['11013331', '9843236']}

(If you want to reduce this to a one-liner, you can:

result = dict((key,list(v[0] for v in valuesiter)
              for key,valuesiter in groupby(input, key=sortkeyfn))

or using the newfangled dict-comprehension form:

result = {key:list(v[0] for v in valuesiter)
              for key,valuesiter in groupby(input, key=sortkeyfn)}

Identify the hash of the commit, using git log, then use git revert <commit> to create a new commit that removes these changes. In a way, git revert is the converse of git cherry-pick -- the latter applies the patch to a branch that's missing it, the former removes it from a branch that has it.

Use Where-Object, like:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | 
Where-Object { $_.CreationTime -gt "03/01/2013" -and $_.CreationTime -lt "03/31/2013" }
Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} | 
Export-Csv 'PATH\scans.csv'

Something like this might help (taken from a working app).

#include <memory>
#include <boost/asio.hpp>
#include <boost/thread.hpp>

struct thread_pool {
  typedef std::unique_ptr<boost::asio::io_service::work> asio_worker;

  thread_pool(int threads) :service(), service_worker(new asio_worker::element_type(service)) {
    for (int i = 0; i < threads; ++i) {
      auto worker = [this] { return service.run(); };
      grp.add_thread(new boost::thread(worker));
    }
  }

  template<class F>
  void enqueue(F f) {
    service.post(f);
  }

  ~thread_pool() {
    service_worker.reset();
    grp.join_all();
    service.stop();
  }

private:
  boost::asio::io_service service;
  asio_worker service_worker;
  boost::thread_group grp;
};

You can use it like this:

thread_pool pool(2);

pool.enqueue([] {
  std::cout << "Hello from Task 1\n";
});

pool.enqueue([] {
  std::cout << "Hello from Task 2\n";
});

Keep in mind that reinventing an efficient asynchronous queuing mechanism is not trivial.

Boost::asio::io_service is a very efficient implementation, or actually is a collection of platform-specific wrappers (e.g. it wraps I/O completion ports on Windows).

If the URL is using https instead of http, you need to add the following line:

parsed_url = URI.parse(url)
http = Net::HTTP.new(parsed_url.host, parsed_url.port)
http.use_ssl = true

Note the additional http.use_ssl = true.

And the more appropriate code which would handle both http and https will be similar to the following one.

url = URI.parse(domain)
req = Net::HTTP::Post.new(url.request_uri)
req.set_form_data({'name'=>'Sur Max', 'email'=>'[email protected]'})
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = (url.scheme == "https")
response = http.request(req)

See more in my blog: EOFError: end of file reached issue when post a form with Net::HTTP.

You can even extend the file module and even set the owner,group & permission through it. (Ref: Ansible file documentation)

- name: Creates directory
  file:
    path: /src/www
    state: directory
    owner: www-data
    group: www-data
    mode: 0775

Even, you can create the directories recursively:

- name: Creates directory
  file:
    path: /src/www
    state: directory
    owner: www-data
    group: www-data
    mode: 0775
    recurse: yes

This way, it will create both directories, if they didn't exist.

Its is called immediatly invoking function expression (IIFE). Mainly associated with the JavaScript closure concept. Main use is to run the function before the global variable changed, so that the expected behaviour of code can be retained.

The solution works fine (thanks!), but if you want to avoid casting and leave the low level work to the JDK, you can use a DataOutputStream to write your int's and a DataInputStream to read them back in. They are automatically treated as unsigned bytes then:

For converting int's to binary bytes;

ByteArrayOutputStream bos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(bos);
int val = 250;
dos.write(byteVal);
...
dos.flush();

Reading them back in:

// important to use a (non-Unicode!) encoding like US_ASCII or ISO-8859-1,
// i.e., one that uses one byte per character
ByteArrayInputStream bis = new ByteArrayInputStream(
   bos.toString("ISO-8859-1").getBytes("ISO-8859-1"));
DataInputStream dis = new DataInputStream(bis);
int byteVal = dis.readUnsignedByte();

Esp. useful for handling binary data formats (e.g. flat message formats, etc.)

do this:

SELECT * FROM table ORDER BY column `name`+0 ASC

Appending the +0 will mean that:

0, 10, 11, 2, 3, 4

becomes :

0, 2, 3, 4, 10, 11

In Java 8, you don't have to use isDebugEnabled() to improve the performance.

https://logging.apache.org/log4j/2.0/manual/api.html#Java_8_lambda_support_for_lazy_logging

import java.util.logging.Logger;
...
Logger.getLogger("hello").info(() -> "Hello " + name);

This is my json data:

[
   {
      "name":"Test",
      "value":"TestValue"
   },
   {
      "name":"Test",
      "value":"TestValue"
   }
]

Powershell script:

$data = Get-Content "Path to json file" | Out-String | ConvertFrom-Json

foreach ($line in $data) {
     $line.name
}

Please see this:

http://jsfiddle.net/JSWorld/Hp4W7/32/

<div ng-repeat="division in divisions | orderBy:['group','sub']">{{division.group}}-{{division.sub}}</div>

You've practically written the format yourself.

yourdate.ToString("yyyyMMddHHmmss")

• MM = two digit month
• mm = two digit minutes
• HH = two digit hour, 24 hour clock
• hh = two digit hour, 12 hour clock

Everything else should be self-explanatory.

Just to update this thread, here is how to add a list (as a json array) into JSONObject. Plz substitute YourClass with your class name;

List<YourClass> list = new ArrayList<>();
JSONObject jsonObject = new JSONObject();

org.codehaus.jackson.map.ObjectMapper objectMapper = new 
org.codehaus.jackson.map.ObjectMapper();
org.codehaus.jackson.JsonNode listNode = objectMapper.valueToTree(list);
org.json.JSONArray request = new org.json.JSONArray(listNode.toString());
jsonObject.put("list", request);

I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:

xmlns:android="http://schemas.android.com/apk/res/android"

could also call it like that:

xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"

This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.

Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.

Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.

I had issue with text nodes, and it was showing wrong index. Here is version to fix it.

function getChildNodeIndex(elem)
{   
    let position = 0;
    while ((elem = elem.previousSibling) != null)
    {
        if(elem.nodeType != Node.TEXT_NODE)
            position++;
    }

    return position;
}

let INT_VALUE=80
let FLOAT_VALUE:Double= 80.9999
let doubleValue=65.0
let DOUBLE_VALUE:Double= 65.56
let STRING_VALUE="Hello"

let str = NSString(format:"%d , %f, %ld, %@", INT_VALUE, FLOAT_VALUE, DOUBLE_VALUE, STRING_VALUE);
 println(str);

For 'long-lived connection' you mentioned, you can use Ratchet for PHP. It's a library built based on Stream Socket functions that PHP has supported since PHP 5.

For client side, you need to use WebSocket that HTML5 supported instead of Socket.io (since you know, socket.io only works with node.js).

In case you still want to use Socket.io, you can try this way: - find & get socket.io.js for client to use - work with Ratchet to simulate the way socket.io does on server

Hope this helps!

It's not immediately obvious from the documentation why the following does not work:

<span style={font-size: 1.7} class="glyphicon glyphicon-remove-sign"></span>

But when doing it entirely inline:

• You need double curly brackets
• You don't need to put your values in quotes
• React will add some default if you omit "em"
• Remember to camelCase style names that have dashes in CSS - e.g. font-size becomes fontSize:
• class is className

The correct way looks like this:

<span style={{fontSize: 1.7 + "em"}} className="glyphicon glyphicon-remove-sign"></span>

Simplest way could come up with for files and input controls, w/out a billion libraries:

  <%
  if (request.getContentType()==null) return;
  // for input type=text controls
  String v_Text = 
  (new BufferedReader(new InputStreamReader(request.getPart("Text1").getInputStream()))).readLine();    

  // for input type=file controls
  InputStream inStr = request.getPart("File1").getInputStream();
  char charArray[] = new char[inStr.available()];
  new InputStreamReader(inStr).read(charArray);
  String contents = new String(charArray);
  %>

You need to begin the session at the top of a page or before you call session code

session_start(); 

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

Nevermind....

public class MainClass {

  public static void main(String[] args) {
    java.util.Date utilDate = new java.util.Date();
    java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
    System.out.println("utilDate:" + utilDate);
    System.out.println("sqlDate:" + sqlDate);

  }

}

Referencing XCopy Force File

For forcing files, we could use pipeline "echo F |":

C:\Trash>xcopy 23.txt 24.txt
Does 24.txt specify a file name
or directory name on the target
(F = file, D = directory)?

C:\Trash>echo F | xcopy 23.txt 24.txt
Does 24.txt specify a file name
or directory name on the target
(F = file, D = directory)? F
C:23.txt
1 File(s) copied

For forcing a folder, we could use /i parameter for xcopy or using a backslash() at the end of the destination folder.

my_randoms = [randint(n1,n2) for x in range(listsize)]

Use below extension to set the maximum character length of a UITextField and UITextView.

Swift 4.0

    private var kAssociationKeyMaxLength: Int = 0
    private var kAssociationKeyMaxLengthTextView: Int = 0
    extension UITextField {


        @IBInspectable var maxLength: Int {
            get {
                if let length = objc_getAssociatedObject(self, &kAssociationKeyMaxLength) as? Int {
                    return length
                } else {
                    return Int.max
                }
            }
            set {
                objc_setAssociatedObject(self, &kAssociationKeyMaxLength, newValue, .OBJC_ASSOCIATION_RETAIN)
                addTarget(self, action: #selector(checkMaxLength), for: .editingChanged)
            }
        }

        @objc func checkMaxLength(textField: UITextField) {
            guard let prospectiveText = self.text,
                prospectiveText.count > maxLength
                else {
                    return
            }

            let selection = selectedTextRange

            let indexEndOfText = prospectiveText.index(prospectiveText.startIndex, offsetBy: maxLength)
            let substring = prospectiveText[..<indexEndOfText]
            text = String(substring)

            selectedTextRange = selection
        }
    }

UITextView

extension UITextView:UITextViewDelegate {


        @IBInspectable var maxLength: Int {
            get {
                if let length = objc_getAssociatedObject(self, &kAssociationKeyMaxLengthTextView) as? Int {
                    return length
                } else {
                    return Int.max
                }
            }
            set {
                self.delegate = self

                objc_setAssociatedObject(self, &kAssociationKeyMaxLengthTextView, newValue, .OBJC_ASSOCIATION_RETAIN)
            }
        }

        public func textViewDidChange(_ textView: UITextView) {
            checkMaxLength(textField: self)
        }
        @objc func checkMaxLength(textField: UITextView) {
            guard let prospectiveText = self.text,
                prospectiveText.count > maxLength
                else {
                    return
            }

            let selection = selectedTextRange

            let indexEndOfText = prospectiveText.index(prospectiveText.startIndex, offsetBy: maxLength)
            let substring = prospectiveText[..<indexEndOfText]
            text = String(substring)

            selectedTextRange = selection
        }
    }

You can set limit below.

Auto incrementing primary key in postgresql:

Step 1, create your table:

CREATE TABLE epictable
(
    mytable_key    serial primary key,
    moobars        VARCHAR(40) not null,
    foobars        DATE
);

Step 2, insert values into your table like this, notice that mytable_key is not specified in the first parameter list, this causes the default sequence to autoincrement.

insert into epictable(moobars,foobars) values('delicious moobars','2012-05-01')
insert into epictable(moobars,foobars) values('worldwide interblag','2012-05-02')

Step 3, select * from your table:

el@voyager$ psql -U pgadmin -d kurz_prod -c "select * from epictable"

Step 4, interpret the output:

mytable_key  |        moobars        |  foobars   
-------------+-----------------------+------------
           1 | delicious moobars     | 2012-05-01
           2 | world wide interblags | 2012-05-02
(2 rows)

Observe that mytable_key column has been auto incremented.

ProTip:

You should always be using a primary key on your table because postgresql internally uses hash table structures to increase the speed of inserts, deletes, updates and selects. If a primary key column (which is forced unique and non-null) is available, it can be depended on to provide a unique seed for the hash function. If no primary key column is available, the hash function becomes inefficient as it selects some other set of columns as a key.

Can I have each consumer receive the same messages? Ie, both consumers get message 1, 2, 3, 4, 5, 6? What is this called in AMQP/RabbitMQ speak? How is it normally configured?

No, not if the consumers are on the same queue. From RabbitMQ's AMQP Concepts guide:

it is important to understand that, in AMQP 0-9-1, messages are load balanced between consumers.

This seems to imply that round-robin behavior within a queue is a given, and not configurable. Ie, separate queues are required in order to have the same message ID be handled by multiple consumers.

Is this commonly done? Should I just have the exchange route the message into two separate queues, with a single consumer, instead?

No it's not, single queue/multiple consumers with each each consumer handling the same message ID isn't possible. Having the exchange route the message onto into two separate queues is indeed better.

As I don't require too complex routing, a fanout exchange will handle this nicely. I didn't focus too much on Exchanges earlier as node-amqp has the concept of a 'default exchange' allowing you to publish messages to a connection directly, however most AMQP messages are published to a specific exchange.

Here's my fanout exchange, both sending and receiving:

var amqp = require('amqp');
var connection = amqp.createConnection({ host: "localhost", port: 5672 });
var count = 1;

connection.on('ready', function () {
  connection.exchange("my_exchange", options={type:'fanout'}, function(exchange) {   

    var sendMessage = function(exchange, payload) {
      console.log('about to publish')
      var encoded_payload = JSON.stringify(payload);
      exchange.publish('', encoded_payload, {})
    }

    // Recieve messages
    connection.queue("my_queue_name", function(queue){
      console.log('Created queue')
      queue.bind(exchange, ''); 
      queue.subscribe(function (message) {
        console.log('subscribed to queue')
        var encoded_payload = unescape(message.data)
        var payload = JSON.parse(encoded_payload)
        console.log('Recieved a message:')
        console.log(payload)
      })
    })

    setInterval( function() {    
      var test_message = 'TEST '+count
      sendMessage(exchange, test_message)  
      count += 1;
    }, 2000) 
 })
})

So, after alot of struggle, I miraculously solved this everannoying issue ! I was trying to mimic a linux terminal and got stuck at the part where it keeps a command history which can be accessed by pressing up or down arrow keys. I found ncurses lib to be painfuly hard to comprehend and slow to learn.

char ch = 0, k = 0;
while(1)
{
  ch = getch();
  if(ch == 27)                  // if ch is the escape sequence with num code 27, k turns 1 to signal the next
    k = 1;
  if(ch == 91 && k == 1)       // if the previous char was 27, and the current 91, k turns 2 for further use
    k = 2;
  if(ch == 65 && k == 2)       // finally, if the last char of the sequence matches, you've got a key !
    printf("You pressed the up arrow key !!\n");
  if(ch == 66 && k == 2)                             
    printf("You pressed the down arrow key !!\n");
  if(ch != 27 && ch != 91)      // if ch isn't either of the two, the key pressed isn't up/down so reset k
    k = 0;
  printf("%c - %d", ch, ch);    // prints out the char and it's int code

It's kind of bold but it explains alot. Good luck !

If using the Script Console method then try using the following instead to take into account if jobs are being grouped into folder containers.

def jobName = "Your Job Name"
def job = Jenkins.instance.getItemByFullName(jobName)

or

def jobName = "My Folder/Your Job Name
def job = Jenkins.instance.getItemByFullName(jobName)

Rather than WNetUseConnection, I would recommend NetUseAdd. WNetUseConnection is a legacy function that's been superceded by WNetUseConnection2 and WNetUseConnection3, but all of those functions create a network device that's visible in Windows Explorer. NetUseAdd is the equivalent of calling net use in a DOS prompt to authenticate on a remote computer.

If you call NetUseAdd then subsequent attempts to access the directory should succeed.

Main Difference Between PUT and PATCH Requests:

Suppose we have a resource that holds the first name and last name of a person.

If we want to change the first name then we send a put request for Update

{ "first": "Michael", "last": "Angelo" }

Here, although we are only changing the first name, with PUT request we have to send both parameters first and last.
In other words, it is mandatory to send all values again, the full payload.

When we send a PATCH request, however, we only send the data which we want to update. In other words, we only send the first name to update, no need to send the last name.

Check the link Regular Expression Demo

use the below reg exp

[a-z] + [^0-9\s.]+|.(?!\d)

here is a test script to run on your server to see what is reliabel.

<?php
$host = gethostname();
$ip = gethostbyname($host);
echo "gethostname and gethostbyname: $host at $ip<br>";
$server = $_SERVER['SERVER_ADDR'];
echo "_SERVER[SERVER_ADDR]: $server<br>";
$my_current_ip=exec("ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'");
echo "exec ifconfig ... : $my_current_ip<br>";
$external_ip = file_get_contents("http://ipecho.net/plain");
echo "get contents ipecho.net: $external_ip<br>";
?>

The only different option in there is using fiel_get_contents rather than curl for the extrernal website lookup.

This is the result of hitting the web page on a shared hosting, free account. (actual server name and IP changed)

gethostname and gethostbyname: freesites.servercluster.com at 345.27.413.51
_SERVER[SERVER_ADDR]: 127.0.0.7
exec ifconfig ... :
get contents ipecho.net: 345.27.413.51

Why needed this? Decided to point A record at server to see if it opens the web page. Later ran script to save ip and update on ghost site on same server to lookup IP and alert if changed.

In this case, good results optained by:

gethostname() & 
gethostbyname($host)
or 
file_get_contents("http://ipecho.net/plain")

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

I'd probably change your example to look like this:

<ul ng-repeat="task in tasks">
  <li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
  <span ng-show="task.editable"><a>Edit</a></span>
</ul>

//js
$scope.enableEdit = function(item){
  item.editable = true;
};

$scope.disableEdit = function(item){
  item.editable = false;
};

I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.

UPDATE
As of 10 of April 2018, this code still works.
Some users reported "not working", if it doesn't work for you, please read below:

From what I've learned, the problem is related with network speed and or screen size.
When YT player starts, it collects the network speed, screen and player sizes, among other information, if the connection is slow or the screen/player size smaller than the quality requested(vq=), a lower quality video is displayed despite the option selected on vq=.

Also make sure you read the comments below.

You could use

=CELL("width", INDIRECT(ADDRESS(ROW(), COLUMN())))

Units:

The amount of "neurons", or "cells", or whatever the layer has inside it.

It's a property of each layer, and yes, it's related to the output shape (as we will see later). In your picture, except for the input layer, which is conceptually different from other layers, you have:

• Hidden layer 1: 4 units (4 neurons)
• Hidden layer 2: 4 units
• Last layer: 1 unit

Shapes

Shapes are consequences of the model's configuration. Shapes are tuples representing how many elements an array or tensor has in each dimension.

Ex: a shape (30,4,10) means an array or tensor with 3 dimensions, containing 30 elements in the first dimension, 4 in the second and 10 in the third, totaling 30*4*10 = 1200 elements or numbers.

The input shape

What flows between layers are tensors. Tensors can be seen as matrices, with shapes.

In Keras, the input layer itself is not a layer, but a tensor. It's the starting tensor you send to the first hidden layer. This tensor must have the same shape as your training data.

Example: if you have 30 images of 50x50 pixels in RGB (3 channels), the shape of your input data is (30,50,50,3). Then your input layer tensor, must have this shape (see details in the "shapes in keras" section).

Each type of layer requires the input with a certain number of dimensions:

• Dense layers require inputs as (batch_size, input_size)
  • or (batch_size, optional,...,optional, input_size)
• 2D convolutional layers need inputs as:
  • if using channels_last: (batch_size, imageside1, imageside2, channels)
  • if using channels_first: (batch_size, channels, imageside1, imageside2)
• 1D convolutions and recurrent layers use (batch_size, sequence_length, features)
  • Details on how to prepare data for recurrent layers

Now, the input shape is the only one you must define, because your model cannot know it. Only you know that, based on your training data.

All the other shapes are calculated automatically based on the units and particularities of each layer.

Relation between shapes and units - The output shape

Given the input shape, all other shapes are results of layers calculations.

The "units" of each layer will define the output shape (the shape of the tensor that is produced by the layer and that will be the input of the next layer).

Each type of layer works in a particular way. Dense layers have output shape based on "units", convolutional layers have output shape based on "filters". But it's always based on some layer property. (See the documentation for what each layer outputs)

Let's show what happens with "Dense" layers, which is the type shown in your graph.

A dense layer has an output shape of (batch_size,units). So, yes, units, the property of the layer, also defines the output shape.

• Hidden layer 1: 4 units, output shape: (batch_size,4).
• Hidden layer 2: 4 units, output shape: (batch_size,4).
• Last layer: 1 unit, output shape: (batch_size,1).

Weights

Weights will be entirely automatically calculated based on the input and the output shapes. Again, each type of layer works in a certain way. But the weights will be a matrix capable of transforming the input shape into the output shape by some mathematical operation.

In a dense layer, weights multiply all inputs. It's a matrix with one column per input and one row per unit, but this is often not important for basic works.

In the image, if each arrow had a multiplication number on it, all numbers together would form the weight matrix.

Shapes in Keras

Earlier, I gave an example of 30 images, 50x50 pixels and 3 channels, having an input shape of (30,50,50,3).

Since the input shape is the only one you need to define, Keras will demand it in the first layer.

But in this definition, Keras ignores the first dimension, which is the batch size. Your model should be able to deal with any batch size, so you define only the other dimensions:

input_shape = (50,50,3)
    #regardless of how many images I have, each image has this shape        

Optionally, or when it's required by certain kinds of models, you can pass the shape containing the batch size via batch_input_shape=(30,50,50,3) or batch_shape=(30,50,50,3). This limits your training possibilities to this unique batch size, so it should be used only when really required.

Either way you choose, tensors in the model will have the batch dimension.

So, even if you used input_shape=(50,50,3), when keras sends you messages, or when you print the model summary, it will show (None,50,50,3).

The first dimension is the batch size, it's None because it can vary depending on how many examples you give for training. (If you defined the batch size explicitly, then the number you defined will appear instead of None)

Also, in advanced works, when you actually operate directly on the tensors (inside Lambda layers or in the loss function, for instance), the batch size dimension will be there.

• So, when defining the input shape, you ignore the batch size: input_shape=(50,50,3)
• When doing operations directly on tensors, the shape will be again (30,50,50,3)
• When keras sends you a message, the shape will be (None,50,50,3) or (30,50,50,3), depending on what type of message it sends you.

Dim

And in the end, what is dim?

If your input shape has only one dimension, you don't need to give it as a tuple, you give input_dim as a scalar number.

So, in your model, where your input layer has 3 elements, you can use any of these two:

• input_shape=(3,) -- The comma is necessary when you have only one dimension
• input_dim = 3

But when dealing directly with the tensors, often dim will refer to how many dimensions a tensor has. For instance a tensor with shape (25,10909) has 2 dimensions.

Defining your image in Keras

Keras has two ways of doing it, Sequential models, or the functional API Model. I don't like using the sequential model, later you will have to forget it anyway because you will want models with branches.

PS: here I ignored other aspects, such as activation functions.

With the Sequential model:

from keras.models import Sequential  
from keras.layers import *  

model = Sequential()    

#start from the first hidden layer, since the input is not actually a layer   
#but inform the shape of the input, with 3 elements.    
model.add(Dense(units=4,input_shape=(3,))) #hidden layer 1 with input

#further layers:    
model.add(Dense(units=4)) #hidden layer 2
model.add(Dense(units=1)) #output layer   

With the functional API Model:

from keras.models import Model   
from keras.layers import * 

#Start defining the input tensor:
inpTensor = Input((3,))   

#create the layers and pass them the input tensor to get the output tensor:    
hidden1Out = Dense(units=4)(inpTensor)    
hidden2Out = Dense(units=4)(hidden1Out)    
finalOut = Dense(units=1)(hidden2Out)   

#define the model's start and end points    
model = Model(inpTensor,finalOut)

Shapes of the tensors

Remember you ignore batch sizes when defining layers:

• inpTensor: (None,3)
• hidden1Out: (None,4)
• hidden2Out: (None,4)
• finalOut: (None,1)

I was having serious problems with

.data('property', value);

It was not setting the data-property attribute.

Started using jQuery's .attr():

Get the value of an attribute for the first element in the set of matched elements or set one or more attributes for every matched element.

.attr('property', value)

to set the value and

.attr('property')

to retrieve the value.

Now it just works!

Just to add on others' contributions....Another way is look at it from a web server and concurrency's point of view...

HTTP is stateless in nature for a reason...In the case of a web server, being stateful means that it would have to remember a user's 'state' for their last connection, and /or keep an open connection to a requester. That would be very expensive and 'stressful' in an application with thousands of concurrent connections...

Being stateless in this case has obvious efficient usage of resources...i.e support a connection in in a single instance of request and response...No overhead of keeping connections open and/or remember anything from the last request...

You can also do this

SELECT    CONCAT(title, ' ', forename, ' ', surname) AS name
FROM      customer c
LEFT JOIN  (
              SELECT * FROM  customer_data ORDER BY id DESC
          ) customer_data ON (customer_data.customer_id = c.customer_id)
GROUP BY  c.customer_id          
WHERE     CONCAT(title, ' ', forename, ' ', surname) LIKE '%Smith%' 
LIMIT     10, 20;

This seems to solve the problem, using the [index: TYPE] array access type, cheers.

interface ScriptNodeList extends NodeList {
    [index: number]: HTMLScriptElement;
}

var script = ( <ScriptNodeList>document.getElementsByName('foo') )[0];

You can use java script for this:-

<asp:TextBox ID="textbox1" runat="server" Width="150px" MaxLength="8" onkeypress="if(event.keyCode<48 || event.keyCode>57)event.returnValue=false;"></asp:TextBox>

I would like to mention that IE9 does not raise the error if you use console.log with developer tools closed on all versions of Windows. On XP it does, but on Windows 7 it doesn't. So if you dropped support for WinXP in general, you're fine using console.log directly.

1. Go to the IIS Manager.
2. open the server name like (PC-Name)\.
3. then double click on the ISAPI and CGI Restriction.
4. then select ASP.NET v4.0.30319(32-bit) Restriction allowed.

Complete answer, ready to be used:

 var Strings = {
        create : (function() {
                var regexp = /{([^{]+)}/g;

                return function(str, o) {
                     return str.replace(regexp, function(ignore, key){
                           return (key = o[key]) == null ? '' : key;
                     });
                }
        })()
};

Call as

Strings.create("My firstname is {first}, my last name is {last}", {first:'Neo', last:'Andersson'});

To attach it to String.prototype:

String.prototype.create = function(o) {
           return Strings.create(this, o);
}

Then use as :

"My firstname is ${first}".create({first:'Neo'});

add apache.commons dependency on your pom.xml

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-io</artifactId>
    <version>1.3.2</version>
</dependency>

And below code works.

StringUtils.substringBetween(String mydata, String "'", String "'")

The problem occurs when your custom class has for property some other class e.g. "Bitmap". What I made is to change the property field from "private Bitmap photo" to "private transient Bitmap photo". However the image is empty after I getIntent() in the receiver activity. Because of this I passed the custom class to the intent and also I've created a byte array from the image and pass it separatly to the intent:

selectedItem is my custom object and getPlacePhoto is his method to get image. I've already set it before and now I just get it first than convert it and pass it separatly:

 Bitmap image = selectedItem.getPlacePhoto();
 image.compress(Bitmap.CompressFormat.PNG, 100, stream);
 byte[] byteArray = stream.toByteArray();
 Intent intent = new Intent(YourPresentActivity.this, 
 TheReceiverActivity.class);
 intent.putExtra("selectedItem", selectedItem);                 
 intent.putExtra("image", byteArray);
 startActivity(intent);            

`

Then in the receiver activity I get my object and the image as byte array, decode the image and set it to my object as photo property.

 Intent intent = getIntent();
 selectedItem = (ListItem) intent.getSerializableExtra("selectedItem");
 byte[] byteArray = getIntent().getByteArrayExtra("image");
 Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, 
 byteArray.length);
 selectedItem.setPhoto(image);

you just need to use word boundary (\b) instead of ^ and $:

Interestingly, if you're just typing at the python interactive interpreter, you have to follow a function with a blank line. This does not work:

def foo(x):
  return x+1
print "last"

although it is perfectly legal python syntax in a file. There are other syntactic differences when typing to the interpreter too, so beware.

After fiddling around for a while, I figured things out, and am posting them here hoping it will help others.

Intuitively, np.where is like asking "tell me where in this array, entries satisfy a given condition".

>>> a = np.arange(5,10)
>>> np.where(a < 8)       # tell me where in a, entries are < 8
(array([0, 1, 2]),)       # answer: entries indexed by 0, 1, 2

It can also be used to get entries in array that satisfy the condition:

>>> a[np.where(a < 8)] 
array([5, 6, 7])          # selects from a entries 0, 1, 2

When a is a 2d array, np.where() returns an array of row idx's, and an array of col idx's:

>>> a = np.arange(4,10).reshape(2,3)
array([[4, 5, 6],
       [7, 8, 9]])
>>> np.where(a > 8)
(array(1), array(2))

As in the 1d case, we can use np.where() to get entries in the 2d array that satisfy the condition:

>>> a[np.where(a > 8)] # selects from a entries 0, 1, 2

array([9])

Note, when a is 1d, np.where() still returns an array of row idx's and an array of col idx's, but columns are of length 1, so latter is empty array.

Select (Select count(y.au_lname) from dbo.authors y
where y.au_lname + y.au_fname <= x.au_lname + y.au_fname) as Counterid,
x.au_lname,x.au_fname from authors x group by au_lname,au_fname
order by Counterid --Alternatively that can be done which is equivalent as above..

It's (Get-NetTCPConnection -LocalPort "port no.").OwningProcess

You can implement this functionality like this
Firstly, using the ls command pointed to the targeted directory. Later using find command filter the result from it. From your case, it sounds like - always the filename starts with a word file***.txt

ls /some/path/here | find . -name 'file*.txt'   (* represents some wild card search)

You can use svn+ssh:, and then it's based on access control to the repository at the given location.

This is how I host a project group repository at my uni, where I can't set up anything else. Just having a directory that the group owns, and running svn-admin (or whatever it was) in there means that I didn't need to do any configuration.

Microsoft recognized the future web open source paradigm and decided to open .NET to other operating systems. .NET Core is a .NET Framework for Mac and Linux. It is a “lightweight” .NET Framework, so some features/libraries are missing.

On Windows, I would still run .NET Framework and Visual Studio 2015. .NET Core is more friendly with the open source world like Node.js, npm, Yeoman, Docker, etc.

You can develop full-fledged web sites and RESTful APIs on Mac or Linux with Visual Studio Code + .NET Core which wasn't possible before. So if you love Mac or Ubuntu and you are a .NET developer then go ahead and set it up.

For Mono vs. .NET Core, Mono was developed as a .NET Framework for Linux which is now acquired by Microsoft (company called Xamarin) and used in mobile development. Eventually, Microsoft may merge/migrate Mono to .NET Core. I would not worry about Mono right now.

Detect mime type of any file

public String getMimeType(Uri uri) {           
    String mimeType = null;
    if (ContentResolver.SCHEME_CONTENT.equals(uri.getScheme())) {
        ContentResolver cr = getAppContext().getContentResolver();
        mimeType = cr.getType(uri);
    } else {
        String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
                .toString());
        mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
                fileExtension.toLowerCase());
    }
    return mimeType;
}

To summarise solutions from a couple of questions/answers:

If you want to get the current scroll offset use:

$(document).scrollTop()

To set the scroll offset use:

$('html,body').scrollTop(x)

To animate the scroll use use:

$('html,body').animate({scrollTop: x});

Or you may do the following

$(this).animate({color:'black'},1000);

But you need to download the color plugin from here.

use the {10,} operator:

The params object is included in $stateParams, but won't be part of the url.

1) In the route configuration:

$stateProvider.state('edit_user', {
    url: '/users/:user_id/edit',
    templateUrl: 'views/editUser.html',
    controller: 'editUserCtrl',
    params: {
        paramOne: { objectProperty: "defaultValueOne" },  //default value
        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>

Example Plunker

According to the W3C (and they are the official source on these things), a space character in the query string (and in the query string only) may be encoded as either "%20" or "+". From the section "Query strings" under "Recommendations":

Within the query string, the plus sign is reserved as shorthand notation for a space. Therefore, real plus signs must be encoded. This method was used to make query URIs easier to pass in systems which did not allow spaces.

According to section 3.4 of RFC2396 which is the official specification on URIs in general, the "query" component is URL-dependent:

3.4. Query Component The query component is a string of information to be interpreted by the resource.

   query         = *uric

Within a query component, the characters ";", "/", "?", ":", "@", "&", "=", "+", ",", and "$" are reserved.

It is therefore a bug in the other software if it does not accept URLs with spaces in the query string encoded as "+" characters.

As for the third part of your question, one way (though slightly ugly) to fix the output from URLEncoder.encode() is to then call replaceAll("\\+","%20") on the return value.

It manages them because int and long are sibling class definitions. They have appropriate methods for +, -, *, /, etc., that will produce results of the appropriate class.

For example

>>> a=1<<30
>>> type(a)
<type 'int'>
>>> b=a*2
>>> type(b)
<type 'long'>

In this case, the class int has a __mul__ method (the one that implements *) which creates a long result when required.

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

We can't reference the result of an aggregate function (for example MAX() ) in a WHERE clause of the same SELECT.

The normative pattern for solving this type of problem is to use an inline view, something like this:

SELECT t.firstName
     , t.Lastname
     , t.id
  FROM mytable t
  JOIN ( SELECT MAX(mx.id) AS max_id
           FROM mytable mx
       ) m
    ON m.max_id = t.id

This is just one way to get the specified result. There are several other approaches to get the same result, and some of those can be much less efficient than others. Other answers demonstrate this approach:

 WHERE t.id = (SELECT MAX(id) FROM ... )

Sometimes, the simplest approach is to use an ORDER BY with a LIMIT. (Note that this syntax is specific to MySQL)

SELECT t.firstName
     , t.Lastname
     , t.id
  FROM mytable t
 ORDER BY t.id DESC
 LIMIT 1

Note that this will return only one row; so if there is more than one row with the same id value, then this won't return all of them. (The first query will return ALL the rows that have the same id value.)

This approach can be extended to get more than one row, you could get the five rows that have the highest id values by changing it to LIMIT 5.

Note that performance of this approach is particularly dependent on a suitable index being available (i.e. with id as the PRIMARY KEY or as the leading column in another index.) A suitable index will improve performance of queries using all of these approaches.

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

Keep it Simple!

Simpler and a Standard solution to increment the number and to retain the dot at the end. Even if you get the css right, it will not work if your HTML is not correct. see below.

CSS

ol {
  counter-reset: item;
}
ol li {
  display: block;
}
ol li:before {
  content: counters(item, ". ") ". ";
  counter-increment: item;
}

SASS

ol {
    counter-reset: item;
    li {
        display: block;
        &:before {
            content: counters(item, ". ") ". ";
            counter-increment: item
        }
    }
}

HTML Parent Child

If you add the child make sure the it is under the parent li.

<!-- WRONG -->
<ol>
    <li>Parent 1</li> <!-- Parent is Individual. Not hugging -->
        <ol> 
            <li>Child</li>
        </ol>
    <li>Parent 2</li>
</ol>

<!-- RIGHT -->
<ol>
    <li>Parent 1 
        <ol> 
            <li>Child</li>
        </ol>
    </li> <!-- Parent is Hugging the child -->
    <li>Parent 2</li>
</ol>

When you don't give a prototype for the function before using it, C assumes that it takes any number of parameters and returns an int. So when you first try to use do_something, that's the type of function the compiler is looking for. Doing this should produce a warning about an "implicit function declaration".

So in your case, when you actually do declare the function later on, C doesn't allow function overloading, so it gets pissy because to it you've declared two functions with different prototypes but with the same name.

Short answer: declare the function before trying to use it.

You probably want something like this overload of String.Join:

String.Join<T> Method (String, IEnumerable<T>)

Docs:

In your example, you'd use

String.Join("", Client);

Have you looked at vincent? Vincent takes Python data objects and converts them to Vega visualization grammar. Vega is a higher-level visualization tool built on top of D3. As compared to D3py, the vincent repo has been updated more recently. Though the examples are all static D3.

more info:

• https://github.com/wrobstory/vincent

• https://pypi.python.org/pypi/vincent/0.1.6

The graphs can be viewed in Ipython, just add this code

vincent.core.initialize_notebook()

Or output to JSON where you can view the JSON output graph in the Vega online editor (http://trifacta.github.io/vega/editor/) or view them on your Python server locally. More info on viewing can be found in the pypi link above.

Not sure when, but the Pandas package should have D3 integration at some point. http://pandas.pydata.org/developers.html

Bokeh is a Python visualization library that supports interactive visualization. Its primary output backend is HTML5 Canvas and uses client/server model.

examples: http://continuumio.github.io/bokehjs/

You can also add hash when page is loading:

location.hash = "noBack";

Then just handle location hash change to add another hash:

$(window).on('hashchange', function() {
    location.hash = "noBack";
});

That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

Adding the Extension Method I am using all over my projects:

public static string Repeat(this string text, int count)
{
    if (!String.IsNullOrEmpty(text))
    {
        return String.Concat(Enumerable.Repeat(text, count));
    }
    return "";
}

Hope someone can take use of it...

Use jQuery....I know you say you're trying to teach someone javascript, but teach him a cleaner technique... for instance, I could:

<select id="navigation">
    <option value="unit_01.htm">Unit 1</option>
    <option value="#5.2">Bookmark 2</option>
</select>

And with a little jQuery, you could do:

$("#navigation").change(function()
{
    document.location.href = $(this).val();
});

Unobtrusive, and with clean separation of logic and UI.

You can also use ng-template, I think that would be more efficient while run time :)

<div ng-if="!test.view; else somethingElse">1</div>
<ng-template #somethingElse>
    <div>2</div>
</ng-template>

It looks as though it's not an array but an arbitrary object. If you have control over the PHP serialization, you might be able to change that.

As raina77ow pointed out, one way to do this in PHP would be by replacing something like this:

json_encode($something) 

with something like:

json_encode(array_values($something))

But don't ignore the other answers here about Object.keys. They should also accomplish what you want if you don't have the ability or the desire to change the serialization of your object.

how will I know that some tables are locked?

You can use SHOW OPEN TABLES command to view locked tables.

how do I unlock tables manually?

If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.

To kill with grep:

kill -9 `pgrep myprocess`

The SQL standard way to implement recursive queries, as implemented e.g. by IBM DB2 and SQL Server, is the WITH clause. See this article for one example of translating a CONNECT BY into a WITH (technically a recursive CTE) -- the example is for DB2 but I believe it will work on SQL Server as well.

Edit: apparently the original querant requires a specific example, here's one from the IBM site whose URL I already gave. Given a table:

CREATE TABLE emp(empid  INTEGER NOT NULL PRIMARY KEY,
                 name   VARCHAR(10),
                 salary DECIMAL(9, 2),
                 mgrid  INTEGER);

where mgrid references an employee's manager's empid, the task is, get the names of everybody who reports directly or indirectly to Joan. In Oracle, that's a simple CONNECT:

SELECT name 
  FROM emp
  START WITH name = 'Joan'
  CONNECT BY PRIOR empid = mgrid

In SQL Server, IBM DB2, or PostgreSQL 8.4 (as well as in the SQL standard, for what that's worth;-), the perfectly equivalent solution is instead a recursive query (more complex syntax, but, actually, even more power and flexibility):

WITH n(empid, name) AS 
   (SELECT empid, name 
    FROM emp
    WHERE name = 'Joan'
        UNION ALL
    SELECT nplus1.empid, nplus1.name 
    FROM emp as nplus1, n
    WHERE n.empid = nplus1.mgrid)
SELECT name FROM n

Oracle's START WITH clause becomes the first nested SELECT, the base case of the recursion, to be UNIONed with the recursive part which is just another SELECT.

SQL Server's specific flavor of WITH is of course documented on MSDN, which also gives guidelines and limitations for using this keyword, as well as several examples.

There are several tools for converting Matlab to Python code.

The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).

Other options include:

• LiberMate: translate from Matlab to Python and SciPy (Requires Python 2, last update 4 years ago).
• OMPC: Matlab to Python (a bit outdated).

Also, for those interested in an interface between the two languages and not conversion:

• pymatlab: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.
• Python-Matlab wormholes: both directions of interaction supported.
• Python-Matlab bridge: use Matlab from within Python, offers matlab_magic for iPython, to execute normal matlab code from within ipython.
• PyMat: Control Matlab session from Python.
• pymat2: continuation of the seemingly abandoned PyMat.
• mlabwrap, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).
• oct2py: run GNU Octave commands from within Python.
• pymex: Embeds the Python Interpreter in Matlab, also on File Exchange.
• matpy: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).
• MatPy: Python package for numerical linear algebra and plotting with a MatLab-like interface.

Btw might be helpful to look here for other migration tips:

• http://bci2000.org/downloads/BCPy2000/Migration.html

On a different note, though I'm not a fortran fan at all, for people who might find it useful there is:

In Linux, folders are case sensitive. I was getting this error because folder name TestAPI and was putting TestApi.

A simple but relatively insecure way would be to use the --net=host option to docker run.

This option makes it so that the container uses the networking stack of the host. Then you can connect to services running on the host simply by using "localhost" as the hostname.

This is easier to configure because you won't have to configure the service to accept connections from the IP address of your docker container, and you won't have to tell the docker container a specific IP address or host name to connect to, just a port.

For example, you can test it out by running the following command, which assumes your image is called my_image, your image includes the telnet utility, and the service you want to connect to is on port 25:

docker run --rm -i -t --net=host my_image telnet localhost 25

If you consider doing it this way, please see the caution about security on this page:

https://docs.docker.com/articles/networking/

It says:

--net=host -- Tells Docker to skip placing the container inside of a separate network stack. In essence, this choice tells Docker to not containerize the container's networking! While container processes will still be confined to their own filesystem and process list and resource limits, a quick ip addr command will show you that, network-wise, they live “outside” in the main Docker host and have full access to its network interfaces. Note that this does not let the container reconfigure the host network stack — that would require --privileged=true — but it does let container processes open low-numbered ports like any other root process. It also allows the container to access local network services like D-bus. This can lead to processes in the container being able to do unexpected things like restart your computer. You should use this option with caution.

Compare-Object $a1 $b1

you can do this easily by using jquery using .css property... try this one: http://api.jquery.com/css/

Do I use one of these then cast to an Int?

Yes. There is no problem doing that. Decimals and doubles can represent integers exactly, so there will be no representation error. (You won't get a case, for instance, where Round returns 4.999... instead of 5.)

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

Annotation that binds a method parameter or method return value to a named model attribute, exposed to a web view.

public String add(@ModelAttribute("specified") Model model) {
    ...
}

If your center content is deep inside other divs then only margin can save you. Nothing else. I face it always when not using a framework like Bootstrap.

Try this instead:

var responseObject = proxy.CallService(new RequestObject
{
    Data = "misc. data",
    Guid = new Guid.NewGuid()
});

This will generate a 'real' Guid value. When you new a reference type, it will give you the default value (which in this case, is all zeroes for a Guid).

When you create a new Guid, it will initialize it to all zeroes, which is the default value for Guid. It's basically the same as creating a "new" int (which is a value type but you can do this anyways):

Guid g1;                    // g1 is 00000000-0000-0000-0000-000000000000
Guid g2 = new Guid();       // g2 is 00000000-0000-0000-0000-000000000000
Guid g3 = default(Guid);    // g3 is 00000000-0000-0000-0000-000000000000
Guid g4 = Guid.NewGuid();   // g4 is not all zeroes

Compare this to doing the same thing with an int:

int i1;                     // i1 is 0
int i2 = new int();         // i2 is 0
int i3 = default(int);      // i3 is 0

I know this question was already answered, but this is what I use:

using (FileStream fStream = File.OpenRead(filename)) {
    return GetHash<MD5>(fStream)
}

Where GetHash:

public static String GetHash<T>(Stream stream) where T : HashAlgorithm {
    StringBuilder sb = new StringBuilder();

    MethodInfo create = typeof(T).GetMethod("Create", new Type[] {});
    using (T crypt = (T) create.Invoke(null, null)) {
        byte[] hashBytes = crypt.ComputeHash(stream);
        foreach (byte bt in hashBytes) {
            sb.Append(bt.ToString("x2"));
        }
    }
    return sb.ToString();
}

Probably not the best way, but it can be handy.

I met the problem too, and I found the way to set style programatically. Maybe you all need it, So I update there.

The third param of View constructor accepts a type of attr in your theme as the source code below:

public TextView(Context context, AttributeSet attrs) {
    this(context, attrs, com.android.internal.R.attr.textViewStyle);
}

So you must pass a type of R.attr.** rather than R.style.**

In my codes, I did following steps:

First, customize a customized attr to be used by themes in attr.xml.

<attr name="radio_button_style" format="reference" />

Second, specific your style in your used theme in style.xml.

 <style name="AppTheme" parent="android:Theme.Translucent">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="radio_button_style">@style/radioButtonStyle</item>
</style>
<style name="radioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">64dp</item>
    <item name="android:background">#000</item>
    <item name="android:button">@null</item>
    <item name="android:gravity">center</item>
    <item name="android:saveEnabled">false</item>
    <item name="android:textColor">@drawable/option_text_color</item>
    <item name="android:textSize">9sp</item>
</style>

At the end, use it!

            RadioButton radioButton = new RadioButton(mContext, null, R.attr.radio_button_style);

the view created programatically will use the specified style in your theme.

You can have a try, and hope it can work for you perfectly.

In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.

http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client

You should have a look at the HttpClient

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");

Make sure your requests ask for the response in JSON using the Accept header like this:

client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));

Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API, if not, then you have to map the objects to your own objects. ASP.NET will convert the JSON you receive to the object you want it to be.

HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
    var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
    foreach (var x in yourcustomobjects)
    {
        //Call your store method and pass in your own object
        SaveCustomObjectToDB(x);
    }
}
else
{
    //Something has gone wrong, handle it here
}

please note that I use .Result for the case of the example. You should consider using the async await pattern here.

fn literally refers to the jquery prototype.

This line of code is in the source code:

jQuery.fn = jQuery.prototype = {
 //list of functions available to the jQuery api
}

But the real tool behind fn is its availability to hook your own functionality into jQuery. Remember that jquery will be the parent scope to your function, so this will refer to the jquery object.

$.fn.myExtension = function(){
 var currentjQueryObject = this;
 //work with currentObject
 return this;//you can include this if you would like to support chaining
};

So here is a simple example of that. Lets say I want to make two extensions, one which puts a blue border, and which colors the text blue, and I want them chained.

jsFiddle Demo

$.fn.blueBorder = function(){
 this.each(function(){
  $(this).css("border","solid blue 2px");
 });
 return this;
};
$.fn.blueText = function(){
 this.each(function(){
  $(this).css("color","blue");
 });
 return this;
};

Now you can use those against a class like this:

$('.blue').blueBorder().blueText();

(I know this is best done with css such as applying different class names, but please keep in mind this is just a demo to show the concept)

This answer has a good example of a full fledged extension.

Using this code you can take input till pressing enter of your keyboard.

char ch[100];
int i;
for (i = 0; ch[i] != '\n'; i++)
{
    scanf("%c ", &ch[i]);
}

As example (DEMO):

HTML:

<div class="header">
  <img src="img/logo.png" alt="logo" />
  <h1>My website name</h1>
</div>

CSS:

.header img {
  float: left;
  width: 100px;
  height: 100px;
  background: #555;
}

.header h1 {
  position: relative;
  top: 18px;
  left: 10px;
}

Updating this topic with a more recent answer, solution that worked for me with version 8.0 of MySQL Connector/ODBC (downloaded at https://downloads.mysql.com/archives/c-odbc/):

Public oConn As ADODB.Connection
Sub MySqlInit()
    If oConn Is Nothing Then
        Dim str As String
        str = "Driver={MySQL ODBC 8.0 Unicode Driver};SERVER=xxxxx;DATABASE=xxxxx;PORT=3306;UID=xxxxx;PWD=xxxxx;"
        Set oConn = New ADODB.Connection
        oConn.Open str
    End If
End Sub

The most important thing on this matter is to check the proper name and version of the installed driver at: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers\

I assume you already know that MongoDB is a NoSQL database system which stores data in the form of BSON documents. Your question, however is about the packages for Node.js.

In terms of Node.js, mongodb is the native driver for interacting with a mongodb instance and mongoose is an Object modeling tool for MongoDB.

Mongoose is built on top of the MongoDB driver to provide programmers with a way to model their data.

EDIT: I do not want to comment on which is better, as this would make this answer opinionated. However I will list some advantages and disadvantages of using both approaches.

Using Mongoose, a user can define the schema for the documents in a particular collection. It provides a lot of convenience in the creation and management of data in MongoDB. On the downside, learning mongoose can take some time, and has some limitations in handling schemas that are quite complex.

However, if your collection schema is unpredictable, or you want a Mongo-shell like experience inside Node.js, then go ahead and use the MongoDB driver. It is the simplest to pick up. The downside here is that you will have to write larger amounts of code for validating the data, and the risk of errors is higher.

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

Remember to press Alt+Enter or add the import.

import android.support.v7.app.AppCompatActivity; 

There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:

sudo apt-get install eclipse eclipse-cdt g++

Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.

Because interfaces specify only what the class is doing, not how it is doing it.

The problem with multiple inheritance is that two classes may define different ways of doing the same thing, and the subclass can't choose which one to pick.

In Java, the equals() method that is inherited from Object is:

public boolean equals(Object other);

In other words, the parameter must be of type Object. This is called overriding; your method public boolean equals(Book other) does what is called overloading to the equals() method.

The ArrayList uses overridden equals() methods to compare contents (e.g. for its contains() and equals() methods), not overloaded ones. In most of your code, calling the one that didn't properly override Object's equals was fine, but not compatible with ArrayList.

So, not overriding the method correctly can cause problems.

I override equals the following everytime:

@Override
public boolean equals(Object other){
    if (other == null) return false;
    if (other == this) return true;
    if (!(other instanceof MyClass)) return false;
    MyClass otherMyClass = (MyClass)other;
    ...test other properties here...
}

The use of the @Override annotation can help a ton with silly mistakes.

Use it whenever you think you are overriding a super class' or interface's method. That way, if you do it the wrong way, you will get a compile error.

You need to have the 'data' array outside of the loop, otherwise it will get reset in every loop and also you can directly push the json. Find the solution below:-

var my_json;
$.getJSON("https://api.thingspeak.com/channels/"+did+"/feeds.json?api_key="+apikey+"&results=300", function(json1) {
console.log(json1);
var data = [];
json1.feeds.forEach(function(feed,i){
    console.log("\n The details of " + i + "th Object are :  \nCreated_at: " + feed.created_at + "\nEntry_id:" + feed.entry_id + "\nField1:" + feed.field1 + "\nField2:" + feed.field2+"\nField3:" + feed.field3);      
    my_json = feed;
    console.log(my_json); //Object {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}
    data.push(my_json);
     //["2017-03-14T01:00:32Z", 33358, "4", "4", "0"]
}); 
console.log(data);

Since version 2.0.0-beta.8 (2016-03-02), Angular now includes a Validators.pattern regex validator.

I like to use gitk name_of_file

This shows a nice list of the changes that happened to a file at each commit, instead of showing the changes to all the files. Makes it easier to track down something that happened.

I assume due diligence here that you confirmed the CPU is actually consumed by SQL process (perfmon Process category counters would confirm this). Normally for such cases you take a sample of the relevant performance counters and you compare them with a baseline that you established in normal load operating conditions. Once you resolve this problem I recommend you do establish such a baseline for future comparisons.

You can find exactly where is SQL spending every single CPU cycle. But knowing where to look takes a lot of know how and experience. Is is SQL 2005/2008 or 2000 ? Fortunately for 2005 and newer there are a couple of off the shelf solutions. You already got a couple good pointer here with John Samson's answer. I'd like to add a recommendation to download and install the SQL Server Performance Dashboard Reports. Some of those reports include top queries by time or by I/O, most used data files and so on and you can quickly get a feel where the problem is. The output is both numerical and graphical so it is more usefull for a beginner.

I would also recommend using Adam's Who is Active script, although that is a bit more advanced.

And last but not least I recommend you download and read the MS SQL Customer Advisory Team white paper on performance analysis: SQL 2005 Waits and Queues.

My recommendation is also to look at I/O. If you added a load to the server that trashes the buffer pool (ie. it needs so much data that it evicts the cached data pages from memory) the result would be a significant increase in CPU (sounds surprising, but is true). The culprit is usually a new query that scans a big table end-to-end.

After click on run icon. If it stuck at waiting for debugger means it is not attached to the app. You have to manually attach by clicking on Attach Debugger to Android process. It is on the right side of run icon. I had focus this icon in linked image.

Yet another solution, assuming the number of items in the folder is not huge:

tar -czf workspace.tar.gz `ls -A`

(ls -A prints normal and hidden files but not "." and ".." as ls -a does.)

On textarea resizing in webkit based browsers:

Setting max-height and max-width on the textarea will not remove the visual resize handle. Try:

resize: none;

(and yes I agree with "try to avoid doing anything which breaks the user's expectation", but sometimes it does make sense, i.e. in the context of a web application)

To customize the look and feel of webkit form elements from scratch:

-webkit-appearance: none;

string name;
char *c_string;

getline(cin, name);

c_string = new char[name.length()];

for (int index = 0; index < name.length(); index++){
    c_string[index] = name[index];
}
c_string[name.length()] = '\0';//add the null terminator at the end of
                              // the char array

This post on the bitbucket issue tracker of virtualenvwrapper may be of interest. It is mentioned there that most of virtualenvwrapper's functions work with the venv virtual environments in Python 3.3.

Here is settings.xml --> C:\maven\conf\settings.xml

jQuery's id selector only returns one result. The descendant and multiple selectors in the second and third statements are designed to select multiple elements. It's similar to:

Statement 1

var length = document.getElementById('a').length;

...Yields one result.

Statement 2

var length = 0;
for (i=0; i<document.body.childNodes.length; i++) {
    if (document.body.childNodes.item(i).id == 'a') {
        length++;
    }
}

...Yields two results.

Statement 3

var length = document.getElementById('a').length + document.getElementsByTagName('div').length;

...Also yields two results.

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

Check if the cell is being registered with self.collectionView.registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String). If so, then remove that line of code.

I had this same problem on Window's and came across this solution. So if someone comes across this problem in Windows the solution for me was to increase the pagefile size, as it was a Memory overcommitment problem for me too.

Windows 8

1. On the Keyboard Press the WindowsKey + X then click System in the popup menu
2. Tap or click Advanced system settings. You might be asked for an admin password or to confirm your choice
3. On the Advanced tab, under Performance, tap or click Settings.
4. Tap or click the Advanced tab, and then, under Virtual memory, tap or click Change
5. Clear the Automatically manage paging file size for all drives check box.
6. Under Drive [Volume Label], tap or click the drive that contains the paging file you want to change
7. Tap or click Custom size, enter a new size in megabytes in the initial size (MB) or Maximum size (MB) box, tap or click Set, and then tap or click OK
8. Reboot your system

Windows 10

1. Press the Windows key
2. Type SystemPropertiesAdvanced
3. Click Run as administrator
4. Under Performance, click Settings
5. Select the Advanced tab
6. Select Change...
7. Uncheck Automatically managing paging file size for all drives
8. Then select Custom size and fill in the appropriate size
9. Press Set then press OK then exit from the Virtual Memory, Performance Options, and System Properties Dialog
10. Reboot your system

Note: I did not have the enough memory on my system for the ~282GB in this example but for my particular case this worked.

EDIT

From here the suggested recommendations for page file size:

There is a formula for calculating the correct pagefile size. Initial size is one and a half (1.5) x the amount of total system memory. Maximum size is three (3) x the initial size. So let's say you have 4 GB (1 GB = 1,024 MB x 4 = 4,096 MB) of memory. The initial size would be 1.5 x 4,096 = 6,144 MB and the maximum size would be 3 x 6,144 = 18,432 MB.

Some things to keep in mind from here:

However, this does not take into consideration other important factors and system settings that may be unique to your computer. Again, let Windows choose what to use instead of relying on some arbitrary formula that worked on a different computer.

Also:

Increasing page file size may help prevent instabilities and crashing in Windows. However, a hard drive read/write times are much slower than what they would be if the data were in your computer memory. Having a larger page file is going to add extra work for your hard drive, causing everything else to run slower. Page file size should only be increased when encountering out-of-memory errors, and only as a temporary fix. A better solution is to adding more memory to the computer.

Use something like this:

class Tree < T > : Dictionary < T, IList< Tree < T > > >  
{  
}  

It's ugly, but I think it will give you what you want. Too bad KeyValuePair is sealed.

I use TINYINT(1) in order to store boolean values in Mysql.

I don't know if there is any advantage to use this... But if i'm not wrong, mysql can store boolean (BOOL) and it store it as a tinyint(1)

put a simple .cmd file in my subfolder with my .ps1 file with the same name, so, for example, a script named "foobar" would have "foobar.ps1" and "foobar.cmd". So to run the .ps1, all I have to do is click the .cmd file from explorer or run the .cmd from a command prompt. I use the same base name because the .cmd file will automatically look for the .ps1 using its own name.

::====================================================================
:: Powershell script launcher
::=====================================================================
:MAIN
    @echo off
    for /f "tokens=*" %%p in ("%~p0") do set SCRIPT_PATH=%%p
    pushd "%SCRIPT_PATH%"

    powershell.exe -sta -c "& {.\%~n0.ps1 %*}"

    popd
    set SCRIPT_PATH=
    pause

The pushd/popd allows you to launch the .cmd file from a command prompt without having to change to the specific directory where the scripts are located. It will change to the script directory then when complete go back to the original directory.

You can also take the pause off if you want the command window to disappear when the script finishes.

If my .ps1 script has parameters, I prompt for them with GUI prompts using .NET Forms, but also make the scripts flexible enough to accept parameters if I want to pass them instead. This way I can just double-click it from Explorer and not have to know the details of the parameters since it will ask me for what I need, with list boxes or other forms.

Try this?

encodeURIComponent('space word').replace(/%20/g,'+')

In my case I found that I have an aggressive plugin for Vim, just restarted it.

tl;dr

LocalTime.parse( "10:30" )  // Parsed as 24-hour time.

java.time

Avoid the troublesome old date-time classes such as Date and Calendar that are now supplanted by the java.time classes.

LocalTime

The java.time classes provide a way to represent the time-of-day without a date and without a time zone: LocalTime

LocalTime lt = LocalTime.of( 10 , 30 );  // 10:30 AM.
LocalTime lt = LocalTime.of( 22 , 30 );  // 22:30 is 10:30 PM.

ISO 8601

The java.time classes use standard ISO 8601 formats by default when generating and parsing strings. These formats use 24-hour time.

String output = lt.toString();

LocalTime.of( 10 , 30 ).toString() : 10:30

LocalTime.of( 22 , 30 ).toString() : 22:30

So parsing 10:30 will be interpreted as 10:30 AM.

LocalTime lt = LocalTime.parse( "10:30" );  // 10:30 AM.

DateTimeFormatter

If you need to generate or parse strings in 12-hour click format with AM/PM, use the DateTimeFormatter class. Tip: make a habit of specifying a Locale.

class Foo {
public:
    Foo(int a) {

    }
}
int func() {
    int a1, a2;
    std::cin >> a1;
    std::cin >> a2;

    Foo f1(a1);
    __asm push a1;
    __asm lea ecx, [this];
    __asm call Foo::Foo(int);

    Foo* f2 = new Foo(a2);
    __asm push sizeof(Foo);
    __asm call operator new;//there's a lot instruction here(depends on system)
    __asm push a2;
    __asm call Foo::Foo(int);

    delete f2;
}

It would be like this in asm. When you're in func, the f1 and pointer f2 has been allocated on stack (automated storage). And by the way, Foo f1(a1) has no instruction effects on stack pointer (esp),It has been allocated, if func wants get the member f1, it's instruction is something like this: lea ecx [ebp+f1], call Foo::SomeFunc(). Another thing the stack allocate may make someone think the memory is something like FIFO, the FIFO just happened when you go into some function, if you are in the function and allocate something like int i = 0, there no push happened.

In my case, I needed to close just one excel window and not the entire application, so, I needed to tell which exact window to close, without saving it.

The following lines work just fine:

Sub test_t()
  Windows("yourfilename.xlsx").Activate
  ActiveWorkbook.Close SaveChanges:=False
End Sub

on macOS (/ OS X), if someone else is having trouble with the OS apparently leaking memory:

• https://github.com/phvu/cuda-smi is useful for quickly checking free memory
• Quitting applications seems to free the memory they use. Quit everything you don't need, or quit applications one-by-one to see how much memory they used.
• If that doesn't cut it (quitting about 10 applications freed about 500MB / 15% for me), the biggest consumer by far is WindowServer. You can Force quit it, which will also kill all applications you have running and log you out. But it's a bit faster than a restart and got me back to 90% free memory on the cuda device.

// copy /tmp/abc.txt to /tmp/abc.txt (target path)

// username and password of 10.1.1.2 is "username" and "password"

sshpass -p "password" scp /tmp/abc.txt [email protected]:/tmp/abc.txt

// install sshpass (ubuntu)

sudo apt-get install sshpass

The best way to do this is to use view port styles. It just does the work and no other techniques needed.

Code:

div{_x000D_
  height:100vh;_x000D_
}

<div></div>

please do read observer pattern

listener interface

public interface OnEventListener {
    void onEvent(EventResult er);
    // or void onEvent(); as per your need
}

then in your class say Event class

public class Event {
    private OnEventListener mOnEventListener;

    public void setOnEventListener(OnEventListener listener) {
        mOnEventListener = listener;
    }

    public void doEvent() {
        /*
         * code code code
         */

         // and in the end

         if (mOnEventListener != null)
             mOnEventListener.onEvent(eventResult); // event result object :)
    }
}

in your driver class MyTestDriver

public class MyTestDriver {
    public static void main(String[] args) {
        Event e = new Event();
        e.setOnEventListener(new OnEventListener() {
             public void onEvent(EventResult er) {
                 // do your work. 
             }
        });
        e.doEvent();
    }
}

We should set to overflow: auto and hide a scrollbar which we don't use for working on unsupporting CSS3 browser. Look at this CSS Overflow; XME.im

for example try this :

<a href="http://www.google.com" id="myLink1">open link 1</a><br/> <a href="http://www.youtube.com" id="myLink2">open link 2</a>

    document.getElementById("myLink1").onclick = function() {
    window.open(
    "http://www.facebook.com"
        );
        return false;
      };

      document.getElementById("myLink2").onclick = function() {
    window.open(
    "http://www.yahoo.com"
        );
        return false;
      };

String.prototype.trim = function(){return his.replace(/^\s+|\s+$/g,"");}
function getHost(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    var _host,_arr;
    if(-1<url.indexOf("://")){
        _arr = url.split('://');
        if(-1<_arr[0].indexOf("/")||-1<_arr[0].indexOf(".")||-1<_arr[0].indexOf("\?")||-1<_arr[0].indexOf("\&")){
            _arr[0] = _arr[0].trim();
            if(0==_arr[0].indexOf("//")) _host = _arr[0].split("//")[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
            else return "";
        }
        else{
            _arr[1] = _arr[1].trim();
            _host = _arr[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
        }
    }
    else{
        if(0==url.indexOf("//")) _host = url.split("//")[1].split("/")[0].trim().split("\?")[0].split("\&")[0];
        else return "";
    }
    return _host;
}
function getHostname(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    return getHost(url).split(':')[0];
}
function getDomain(url){
    if("undefined"==typeof(url)||null==url) return "";
    url = url.trim(); if(""==url) return "";
    return getHostname(url).replace(/([a-zA-Z0-9]+.)/,"");
}

I had two significant errors in my program. From the other answers, I learned in a single java program, one can not declare two classes as "public". So I changed the access specifier, but got another error as added to my question as "EDIT" that "Selection does not contain a main type". Finally I observed I forgot to add "String args[]" part in my main method. That's why the code was not working. After rectification, it worked as expected.

Since the login page is a separate page, I am assuming that you want to redirect to the page that the user reached the login page from.

$_SERVER['REQUEST_URI'] will simply hold the current page. What you want to do is use $_SERVER['HTTP_REFERER']

So save the HTTP_REFERER in a hidden element on your form <input type="hidden" name="referer" value="<?= $_SERVER['HTTP_REFERER'] ?>" /> but keep in mind that in the PHP that processes the form you will need some logic that redirects back to the login page if login fails but also to check that the referer is actually your website, if it isn't, then redirect back to the homepage.

After a lot of struggle, I have found that the solution is a lot more simple that you could imagine:

Instead of autocomplete="off" just simply use autocomplete="false" ;)

Try this...

$(document).ready(function () {
    $('input').attr('autocomplete', 'false');
});

try something like this

 URL u = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
 InputStream in = u.openStream();

Then use it as any plain old input stream

As an addition to @dulgan's answer, it is always a good approach to use firstObject over objectAtIndex:0, because while first one returns nil if there is no object in the array, latter one throws exception.

UIViewController *rootViewController = self.navigationController.rootViewController;

Alternatively, it'd be a big plus for you to create a category named UINavigationController+Additions and define your method in that.

@interface UINavigationController (Additions)

- (UIViewController *)rootViewController;

@end

@implementation UINavigationController (Additions)

- (UIViewController *)rootViewController
{
    return self.viewControllers.firstObject;
}

@end

You can do that using Requestify, a very simple and cool HTTP client I wrote for nodeJS, it support easy use of cookies and it also supports caching.

To perform a request with a cookie attached just do the following:

var requestify = require('requestify');
requestify.post('http://google.com', {}, {
    cookies: {
        sessionCookie: 'session-cookie-data'   
    }
});

For me it was - you can't omit prefixing the current DB table if you create a FK for a non-current DB referencing the current DB:

USE currrent_db;
ALTER TABLE other_db.tasks ADD CONSTRAINT tasks_fk FOREIGN KEY (user_id) REFERENCES currrent_db.users (id);

If I omit "currrent_db." for users table, I get the FK error. Interesting that SHOW ENGINE INNODB STATUS; shows nothing in this case.

when it comes to subquery and co-related query both have inner query and outer query the only difference is in subquery the inner query doesn't depend on outer query, whereas in co-related inner query depends on outer.

if is there only one Top-Level Container then last lines in GUI constructor would be for example

.
.
.
myFrame.setVisible(true);
EventQueue.invokeLater(new Runnable() {

   @Override
     public void run() {
         myComponent.grabFocus();
         myComponent.requestFocus();//or inWindow
     }
});

The above didn't work for me in 3.3. Try this instead (YMMV, etc)

import urllib.request
url = "http://www.google.com/"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
print (response.read().decode('utf-8'))

System.TypeInitializationException happens when the code that gets executed during the process of loading the type throws an exception.

When .NET loads the type, it must prepare all its static fields before the first time that you use the type. Sometimes, initialization requires running code. It is when that code fails that you get a System.TypeInitializationException.

In your specific case, the following three static fields run some code:

private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);

Note that s_bstCommonAppData depends on s_commonAppData, but it is declared ahead of its dependency. Therefore, the value of s_commonAppData is null at the time that the Path.Combine is called, resulting in ArgumentNullException. Same goes for the s_bstUserDataDir and s_bstCommonAppData: they are declared in reverse order to the desired order of initialization.

Re-order the lines to fix this problem:

private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");

If you use eclipse you can install Data Tools Platform plugin on it and use it for every DB engines including MS SQLServer. It just needs to get JDBC driver for that DB engine.

Adding another solution for this issue.

in my Global.asax.cs file I had disabled attempted php files from being consumed by the MVC pipeline using the following:

routes.IgnoreRoute( "{*php}" );

I had done these previously in a MVC2 project and it worked fine, but doing this in my MVC 3 app caused the issue reported above.

I'm not familiar with grep but with Select-String you can do:

Get-ChildItem filename.txt | Select-String -Pattern <regexPattern>

You can also do that with Get-Content:

(Get-Content filename.txt) -match 'pattern'

Use this line simply inside your head with

       window.location.reload(true);

It will load your current page or view.

Although it is probably easiest to generate a new CSR using IIS (like @rainabba said), assuming you have the intermediate certificates there are some online converters out there - for instance: https://www.sslshopper.com/ssl-converter.html

This will allow you to create a PFX from your certificate and private key without having to install another program.

The structure of your menu code is the issue:

cin >> choice;   // new line character is left in the stream

 switch ( ... ) {
     // We enter the handlers, '\n' still in the stream
 }

cin.ignore();   // Put this right after cin >> choice, before you go on
                // getting input with getline.

Took me couple trials, had same issue, this worked for me:

Check your spelling at -

(BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];

I corrected mine at textField instead of textfield, capitalise "F"... and bingo!! it worked..

You specify the escape character. Documentation here:
http://msdn.microsoft.com/en-us/library/ms179859.aspx

Twood, Visibility expression is the expressions you write on how you want the "visibility" to behave. So, if you would want to hide or show the textbox, you want to write this:

=IIf((CountRows("ScannerStatisticsData")=0),True,False)

This means, if the dataset is 0, you want to hide the textbox.

You can wrap those elements in anchor tag

like this

<a href="your link here"> <i class="fa fa-dribbble fa-4x"></i></a>
<a href="your link here"> <i class="fa fa-behance-square fa-4x"></i></a>
<a href="your link here"> <i class="fa fa-linkedin-square fa-4x"></i></a>
<a href="your link here"> <i class="fa fa-twitter-square fa-4x"></i></a>
<a href="your link here"> <i class="fa fa-facebook-square fa-4x"></i></a>

Note: Replace href="your link here" with your desired link e.g. href="https://www.stackoverflow.com".

One more solution, version for the 'years' difference:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('year', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

    2

(1 row)

And the same trick for the months:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('month', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

   23

(1 row)

In real life query there can be some timestamp sequences grouped by hour/day/week/etc instead of generate_series.

This 'count(distinct(date_trunc('month', ts)))' can be used right in the 'left' side of the select:

SELECT sum(a - b)/count(distinct(date_trunc('month', c))) FROM d

I used generate_series() here just for the brevity.

Use the below code to find the count of number of matches that the regex finds in your input

        Pattern p = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);// "regex" here indicates your predefined regex.
        Matcher m = p.matcher(pattern); // "pattern" indicates your string to match the pattern against with
        boolean b = m.matches();
        if(b)
        count++;
        while (m.find())
        count++;

This is a generalized code not specific one though, tailor it to suit your need

Please feel free to correct me if there is any mistake.

Recommendation from JAVA is to assign to null

From https://docs.oracle.com/cd/E19159-01/819-3681/abebi/index.html

Explicitly assigning a null value to variables that are no longer needed helps the garbage collector to identify the parts of memory that can be safely reclaimed. Although Java provides memory management, it does not prevent memory leaks or using excessive amounts of memory.

An application may induce memory leaks by not releasing object references. Doing so prevents the Java garbage collector from reclaiming those objects, and results in increasing amounts of memory being used. Explicitly nullifying references to variables after their use allows the garbage collector to reclaim memory.

One way to detect memory leaks is to employ profiling tools and take memory snapshots after each transaction. A leak-free application in steady state will show a steady active heap memory after garbage collections.

Some compilers support compound literals as an extention, allowing this construct:

Customer customerRecords[2];
customerRecords[0] = (Customer){25, "Bob Jones"};
customerRecords[1] = (Customer){26, "Jim Smith"};

But it's rather unportable.

You can pass using -e parameters with docker run .. command as mentioned here and as mentioned by @errata.

However, the possible downside of this approach is that your credentials will be displayed in the process listing, where you run it.

To make it more secure, you may write your credentials in a configuration file and do docker run with --env-file as mentioned here. Then you can control the access of that config file so that others having access to that machine wouldn't see your credentials.

.form-group .required .control-label:after should probably be .form-group.required .control-label:after. The removal of the space between .form-group and .required is the change.

Here is the better way, just pass your whole model

import torch.nn as nn
def initialize_weights(model):
    # Initializes weights according to the DCGAN paper
    for m in model.modules():
        if isinstance(m, (nn.Conv2d, nn.ConvTranspose2d, nn.BatchNorm2d)):
            nn.init.normal_(m.weight.data, 0.0, 0.02)
        # if you also want for linear layers ,add one more elif condition 

Dns.GetHostEntry(Dns.GetHostName()).AddressList[1].MapToIPv4() //returns 192.168.14.1

This can also be done by using partial from the standard library functools, like this:

from functools import partial
#(...)
action_with_arg = partial(action, arg)
button = Tk.Button(master=frame, text='press', command=action_with_arg)

I'm fairly sure the primary monitor is the default. If the app was coded decently, when it's closed, it'll remember where it was last at and will reopen there, but -- as you've noticed -- it isn't a default behavior.

EDIT: The way I usually do it is to have the location stored in the app's settings. On load, if there is no value for them, it defaults to the center of the screen. On closing of the form, it records its position. That way, whenever it opens, it's where it was last. I don't know of a simple way to tell it to launch onto the second monitor the first time automatically, however.

you can write !important in front of background-color property value like this it will change the color of links.

.nav-link {
    color: white !important;
}

Most of the simple programs have computation time in milli-seconds. So, i suppose, you will find this useful.

#include <time.h>
#include <stdio.h>

int main(){
    clock_t start = clock();
    // Execuatable code
    clock_t stop = clock();
    double elapsed = (double)(stop - start) * 1000.0 / CLOCKS_PER_SEC;
    printf("Time elapsed in ms: %f", elapsed);
}

If you want to compute the runtime of the entire program and you are on a Unix system, run your program using the time command like this time ./a.out

public void sampleConnection() throws Exception {

     Configuration cfg = new Configuration().addResource("hibernate.cfg.xml").configure();
     StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
     SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
     Session session = sessionFactory.openSession();
     logger.debug(" connection with the database created successfuly.");
}

I have a function which returns a CLOB and I was seeing the above error when I'd forgotten to declare the return value as an output parameter. Initially I had:

        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        };
}

The buildSqlParameters method should have included the SqlOutParameter:

public SqlParameter[] buildSqlParameters() {
    return new SqlParameter[]{
        new SqlParameter("p_names", Types.VARCHAR),
        new SqlParameter("p_format", Types.VARCHAR),
        new SqlParameter("p_units", Types.VARCHAR),
        new SqlParameter("p_datums", Types.VARCHAR),
        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        new SqlOutParameter("l_clob", Types.CLOB)  // <-- This was missing!
    }; 
}

The Miro video converter does a beautiful job and is drag-n-drop. http://www.mirovideoconverter.com/

BTW it's FREE and also very good for mobile device encoding.
