Programs & Examples On #Inline editing

Example using std::vector

#include <iostream>
#include <string>
#include <algorithm>
#include <vector>

int main()
{
    /// Initilaize vector using intitializer list ( requires C++11 )
    std::vector<std::string> names = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    // Sort names using std::sort
    std::sort(names.begin(), names.end() );

    // Print using range-based and const auto& for ( both requires C++11 )
    for(const auto& currentName : names)
    {
        std::cout << currentName << std::endl;
    }

    //... or by using your orignal for loop ( vector support [] the same way as plain arrays )
    for(int y = 0; y < names.size(); y++)
    {
       std:: cout << names[y] << std::endl; // you were outputting name[z], but only increasing y, thereby only outputting element z ( 14 )
    }
    return 0;

}

This completely avoids using plain arrays, and lets you use the std::sort function. You might need to update you compiler to use the = {...} You can instead add them by using vector.push_back("name")

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}

gravity--Applies to its own view.

layout-gravity---Applies to view related to its parent.

Set the margin for body at 0 and that will fix it.

body {
   margin: 0;
}

@Servy's answer was nice and succinct. I think it can be even simpler?

private static string[] suffixes = new [] { " B", " KB", " MB", " GB", " TB", " PB" };

public static string ToSize(double number, int precision = 2)
{
    // unit's number of bytes
    const double unit = 1024;
    // suffix counter
    int i = 0;
    // as long as we're bigger than a unit, keep going
    while(number > unit)
    {
        number /= unit;
        i++;
    }
    // apply precision and current suffix
    return Math.Round(number, precision) + suffixes[i];
}

Valid longitudes are from -180 to 180 degrees.

Latitudes are supposed to be from -90 degrees to 90 degrees, but areas very near to the poles are not indexable.

So exact limits, as specified by EPSG:900913 / EPSG:3785 / OSGEO:41001 are the following:

• Valid longitudes are from -180 to 180 degrees.
• Valid latitudes are from -85.05112878 to 85.05112878 degrees.

As others have said SQL 2008 comes with a Filestream type that allows you to store a filename or identifier as a pointer in the db and automatically stores the image on your filesystem which is a great scenario.

If you're on an older database, then I'd say that if you're storing it as blob data, then you're really not going to get anything out of the database in the way of searching features, so it's probably best to store an address on a filesystem, and store the image that way.

That way you also save space on your filesystem, as you are only going to save the exact amount of space, or even compacted space on the filesystem.

Also, you could decide to save with some structure or elements that allow you to browse the raw images in your filesystem without any db hits, or transfer the files in bulk to another system, hard drive, S3 or another scenario - updating the location in your program, but keep the structure, again without much of a hit trying to bring the images out of your db when trying to increase storage.

Probably, it would also allow you to throw some caching element, based on commonly hit image urls into your web engine/program, so you're saving yourself there as well.

I'm using Tortoise SVN, after tring all solution in this page and not working,

I finally back up the problem file. and use Repo Browser delete the problem file in it, then update local folder so the file in local folder is deleted. Then copy back the backup file and Add > Commit, then I can update successfully.

The only disadvantage of this method is the history of this file will be removed.

Ctrl+C terminates the main thread, but because your threads aren't in daemon mode, they keep running, and that keeps the process alive. We can make them daemons:

f = FirstThread()
f.daemon = True
f.start()
s = SecondThread()
s.daemon = True
s.start()

But then there's another problem - once the main thread has started your threads, there's nothing else for it to do. So it exits, and the threads are destroyed instantly. So let's keep the main thread alive:

import time
while True:
    time.sleep(1)

Now it will keep print 'first' and 'second' until you hit Ctrl+C.

Edit: as commenters have pointed out, the daemon threads may not get a chance to clean up things like temporary files. If you need that, then catch the KeyboardInterrupt on the main thread and have it co-ordinate cleanup and shutdown. But in many cases, letting daemon threads die suddenly is probably good enough.

Making it private would still mean it appears in the header. I tend to use "the weakest" way that works. See this classic article by Scott Meyers: http://www.ddj.com/cpp/184401197 (it's about functions, but can be applied here as well).

Add poster="placeholder.png" to the video tag.

<video width="470" height="255" poster="placeholder.png" controls>
    <source src="video.mp4" type="video/mp4">
    <source src="video.ogg" type="video/ogg">
    <source src="video.webm" type="video/webm">
    <object data="video.mp4" width="470" height="255">
    <embed src="video.swf" width="470" height="255">
    </object>
</video>

Does that work?

Another way is to use an array as a type, e.g.:

ObjectMapper objectMapper = new ObjectMapper();
MyPojo[] pojos = objectMapper.readValue(json, MyPojo[].class);

This way you avoid all the hassle with the Type object, and if you really need a list you can always convert the array to a list by:

List<MyPojo> pojoList = Arrays.asList(pojos);

IMHO this is much more readable.

And to make it be an actual list (that can be modified, see limitations of Arrays.asList()) then just do the following:

List<MyPojo> mcList = new ArrayList<>(Arrays.asList(pojos));

Ignoring the jQuery this can be done using ::placeholder of an input element.

<form role="form">
  <div class="form-group">
    <input type="text" class="form-control name" placeholder="&#xF002;"/>
  </div>
</form>

The css part

input.name::placeholder{ font-family:fontAwesome; font-size:[size needed]; color:[placeholder color needed] }

input.name{ font-family:[font family you want to specify] }

THE BEST PART: You can have different font family for placeholder and text

Using some text manipulation we can separate each unit of time and then sum them together with their millisecond coefficients.

To show the formulas in the cells use CTRL + `

Just add the directory on the command line:

svn checkout svn://192.168.1.1/projectname/ target-directory/

I realize this is an old question, but it pops up in Google when you search for 'javascript dictionaries', so I'd like to add to the above answers that in ECMAScript 6, the official Map object has been introduced, which is a dictionary implementation:

var dict = new Map();
dict.set("foo", "bar");

//returns "bar"
dict.get("foo");

Unlike javascript's normal objects, it allows any object as a key:

var foo = {};
var bar = {};
var dict = new Map();
dict.set(foo, "Foo");
dict.set(bar, "Bar");

//returns "Bar"
dict.get(bar);

//returns "Foo"
dict.get(foo);

//returns undefined, as {} !== foo and {} !== bar
dict.get({});

There is a much better and easy way that we can do this using ramda.js. Code sample here

const ary = [5, 5, 5, 2, 2, 2, 2, 2, 9, 4]; R.countBy(r=> r)(ary) countBy documentation is at documentation

Old question but throwing my solution into the ring for completeness. I needed this when I needed a specific find but a different create if it doesn't exist.

def self.find_by_or_create_with(args, attributes) # READ CAREFULLY! args for finding, attributes for creating!
        obj = self.find_or_initialize_by(args)
        return obj if obj.persisted?
        return obj if obj.update_attributes(attributes) 
end

<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic" 
    ValidationGroup="g1" runat="server" ControlToValidate="ControlID"

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

In the root web.config for your project, under the system.web node:

<system.web>
    <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" />
...

In addition, I had to add this under the system.webServer node or I got a security error for my long query strings:

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxUrl="10999" maxQueryString="2097151" />
      </requestFiltering>
    </security>
...

I Prefer these one:

Creates Bitmap from InputStream and returns it:

    public static  Bitmap downloadImage(String url) {
        Bitmap bitmap = null;
        InputStream stream = null;
        BitmapFactory.Options bmOptions = new BitmapFactory.Options();
        bmOptions.inSampleSize = 1;

        try {
            stream = getHttpConnection(url);
            bitmap = BitmapFactory.decodeStream(stream, null, bmOptions);
            stream.close();
        }
        catch (IOException e1) {
            e1.printStackTrace();
            System.out.println("downloadImage"+ e1.toString());
        }
        return bitmap;
    }

  // Makes HttpURLConnection and returns InputStream

 public static  InputStream getHttpConnection(String urlString)  throws IOException {

        InputStream stream = null;
        URL url = new URL(urlString);
        URLConnection connection = url.openConnection();

        try {
            HttpURLConnection httpConnection = (HttpURLConnection) connection;
            httpConnection.setRequestMethod("GET");
            httpConnection.connect();

            if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
                stream = httpConnection.getInputStream();
            }
        }
        catch (Exception ex) {
            ex.printStackTrace();
            System.out.println("downloadImage" + ex.toString());
        }
        return stream;
    }

REMEMBER :

Android includes two HTTP clients: HttpURLConnection and Apache HTTP Client. For Gingerbread and later, HttpURLConnection is the best choice.

From Android 3.x Honeycomb or later, you cannot perform Network IO on the UI thread and doing this throws android.os.NetworkOnMainThreadException. You must use Asynctask instead as shown below

/**     AsyncTAsk for Image Bitmap  */
    private class AsyncGettingBitmapFromUrl extends AsyncTask<String, Void, Bitmap> {


        @Override
        protected Bitmap doInBackground(String... params) {

            System.out.println("doInBackground");

            Bitmap bitmap = null;

            bitmap = AppMethods.downloadImage(params[0]);

            return bitmap;
        }

        @Override
        protected void onPostExecute(Bitmap bitmap) {

            System.out.println("bitmap" + bitmap);

        }
    }

Best solution so far that I have seen is in FastAdapter library for recycler views. It has a EndlessRecyclerOnScrollListener.

Here is an example usage: EndlessScrollListActivity

Once I used it for endless scrolling list I have realised that the setup is a very robust. I'd definitely recommend it.

This should work:

if (!string.IsNullOrWhiteSpace(dateTimeEnd))
    eventCustom.DateTimeEnd = DateTime.Parse(dateTimeEnd);
else
    eventCustom.DateTimeEnd = null;

Note that this will throw an exception if the string is not in the correct format.

Try this

Window > Show View > Package Explorer

it will display the hidden 'Package Explorer' on your eclipse IDE.

• 'Window' is in your Eclipse' menubar.

you need double quotes in all your three if statements, eg.:

IF "%a%"=="2" (

@echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION
cls
title ~USB Wizard~
echo What do you want to do?
echo 1.Enable/Disable USB Storage Devices.
echo 2.Enable/Disable Writing Data onto USB Storage.
echo 3.~Yet to come~.


set "a=%globalparam1%"
goto :aCheck
:aPrompt
set /p "a=Enter Choice: "
:aCheck
if "%a%"=="" goto :aPrompt
echo %a%

IF "%a%"=="2" (
    title USB WRITE LOCK
    echo What do you want to do?
    echo 1.Apply USB Write Protection
    echo 2.Remove USB Write Protection
    ::param1
    set "param1=%globalparam2%"
    goto :param1Check
    :param1Prompt
    set /p "param1=Enter Choice: "
    :param1Check
    if "!param1!"=="" goto :param1Prompt

    if "!param1!"=="1" (
         REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000001
         USB Write is Locked!
    )
    if "!param1!"=="2" (
         REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000000
         USB Write is Unlocked!
    )
)
pause

It's better to avoid any kind of loops, just remove all elements directly like this:

$("#mytable > tbody").html("");

$.getJSon expects a callback functions either you pass it to the callback function or in callback function assign it to global variale.

var globalJsonVar;

    $.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
               //do some thing with json  or assign global variable to incoming json. 
                globalJsonVar=json;
          });

IMO best is to call the callback function. which is nicer to eyes, readability aspects.

$.getJSON("http://127.0.0.1:8080/horizon-update", callbackFuncWithData);

function callbackFuncWithData(data)
{
 // do some thing with data 
}

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

First shift the column:

df['gdp'] = df['gdp'].shift(-1)

Second remove the last row which contains an NaN Cell:

df = df[:-1]

Third reset the index:

df = df.reset_index(drop=True)

I was getting similar error and please see below how I resolved it.

My directory structure: /opt/git/project.git and git user is git

$ cd /opt/git/project.git
$ sudo chown -R git:git .

chown with -R option recursively changes the ownership and and group (since i typed git:git in above command) of the current directory. chown -R is necessary since git changes many files inside your git directory when you push to the repository.

Here is my Black Eclipse Custom CSS for Chrome Theme Plugin. Usable with eclipse 4.2 and 4.3. Main goal was to make it look nice in ubuntu, besides making it "darker".

Caution: May or may not work on Windows Systems, only checked with ubuntu.

Required: Chrome Theme and Color Theme plugin

1. Install those mentioned plugins. They can be found in the eclipse marketplace.

2. Install my variant of Gedit Oblivion Theme in Color Theme and activate it. (http://eclipsecolorthemes.org/?view=theme&id=12544)

3. Insert the custom css in css editor of Chrome Theme. I spend several hours with CSS Spy to find out all the relevant information to make eclipse as black and this file as small as possible. There is also an .epf File for the Chrome Theme plugin preferences you should import. You can get it from my dropbox: https://www.dropbox.com/sh/ye5tosl3cjhx96d/yL-_Y5j1PE

In the end your eclipse will look like this:

Have Fun!

System32 is where Windows historically placed all 32bit DLLs, and System was for the 16bit DLLs. When microsoft created the 64 bit OS, everyone I know of expected the files to reside under System64, but Microsoft decided it made more sense to put 64bit files under System32. The only reasoning I have been able to find, is that they wanted everything that was 32bit to work in a 64bit Windows w/o having to change anything in the programs -- just recompile, and it's done. The way they solved this, so that 32bit applications could still run, was to create a 32bit windows subsystem called Windows32 On Windows64. As such, the acronym SysWOW64 was created for the System directory of the 32bit subsystem. The Sys is short for System, and WOW64 is short for Windows32OnWindows64.
Since windows 16 is already segregated from Windows 32, there was no need for a Windows 16 On Windows 64 equivalence. Within the 32bit subsystem, when a program goes to use files from the system32 directory, they actually get the files from the SysWOW64 directory. But the process is flawed.

It's a horrible design. And in my experience, I had to do a lot more changes for writing 64bit applications, that simply changing the System32 directory to read System64 would have been a very small change, and one that pre-compiler directives are intended to handle.

Ok, I know there is an accepted answer but… for more special cases you also could use this one:

array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);

Or in a more un-complex way:

function printItem($n){
    echo $n['filename'];
    echo $n['filepath'];
}

array_map('printItem', $array);

This will allow you to manipulate the data in an easier way.

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

create a full-width View with alignItems: "center" then insert desired children inside.

import React from "react";
import {View} from "react-native";

export default class AbsoluteComponent extends React.Component {
  render(){
    return(
     <View style={{position: "absolute", left: 0, right: 0, alignItems: "center"}}>
      {this.props.children}
     </View>    
    )
  }
}

you can add properties like bottom: 30 for bottom aligned component.

To rename file using refactoring (which also updates all occurrences of name in other scripts):

1. Save changes to file before using refactoring/renaming
2. In Project Explorer view, right-click file to be renamed and select Refactor | Rename -or- select it and go to Refactor | Rename from the Menu Bar. A Rename File dialog will appear.
3. Enter the file's new name.
4. Check the "Update references" box and click Preview.
5. You can scroll through changes using the Select Next / Previous Change scrolling arrows.
6. Press OK to rename file and update all occurrences of the script name in other scripts.

See "PHP Developer User Guide > Tasks > Using Refactoring > Renaming Files".

Here's my own:

{
    static void Main(string[] args)
    {
        var tree = new Tree<string>()
            .Begin("Fastfood")
                .Begin("Pizza")
                    .Add("Margherita")
                    .Add("Marinara")
                .End()
                .Begin("Burger")
                    .Add("Cheese burger")
                    .Add("Chili burger")

        if (m_Stack.Count == 0)
        {
            var node = new TreeNode<T>(val, null);
            Nodes.Add(node);

      Marinara
   Burger
      Cheese burger
      Chili burger
      Rice burger

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

Use the unlink function of php, just pass exact path to your file to unlink function :

unlink($file_path);

Do not forget to create complete path of your file if it is not stored in the DB. e.g

$file_path = app_path().'/images/news/'.$news->photo;

If you are using ASP.NET MVC – you do not need an additional HTTP handler and some modifications of the web.config file. All you need – just to add some simple action in a Home/Common controller:

[HttpPost]
public JsonResult KeepSessionAlive() {
    return new JsonResult {Data = "Success"};
}

, write a piece of JavaScript code like this one (I have put it in one of site’s JavaScript file):

var keepSessionAlive = false;
var keepSessionAliveUrl = null;

function SetupSessionUpdater(actionUrl) {
    keepSessionAliveUrl = actionUrl;
    var container = $("#body");
    container.mousemove(function () { keepSessionAlive = true; });
    container.keydown(function () { keepSessionAlive = true; });
    CheckToKeepSessionAlive();
}

function CheckToKeepSessionAlive() {
    setTimeout("KeepSessionAlive()", 5*60*1000);
}

function KeepSessionAlive() {
    if (keepSessionAlive && keepSessionAliveUrl != null) {
        $.ajax({
            type: "POST",
            url: keepSessionAliveUrl,
            success: function () { keepSessionAlive = false; }
        });
    }
    CheckToKeepSessionAlive();
}

, and initialize this functionality by calling a JavaScript function:

SetupSessionUpdater('/Home/KeepSessionAlive');

Please note! I have implemented this functionality only for authorized users (there is no reason to keep session state for guests in most cases) and decision to keep session state active is not only based on – is browser open or not, but authorized user must do some activity on the site (move a mouse or type some key).

You should use something like this:

<div style="text-align:center">  
    <input type="submit" />  
</div>  

Or you could use something like this. By giving the element a width and specifying auto for the left and right margins the element will center itself in its parent.

<input type="submit" style="width: 300px; margin: 0 auto;" />

In my case, I was able to find the problem by temporarily catching the exception, descending into causes as needed (based on how deep the IllegalAnnotationException was), and calling getErrors() on it.

    try {
        // in my case, this was what gave me an exception
        endpoint.publish("/MyWebServicePort");
    // I got a WebServiceException caused by another exception, which was caused by the IllegalAnnotationsException
    } catch (WebServiceException e) {
        // Incidentally, I need to call getCause().getCause() on it, and cast to IllegalAnnotationsException before calling getErrors()
        System.err.println(((com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException)e.getCause().getCause()).getErrors());
    }

$('.button1').click(function() {
   document.location.href='/index.php?id=' + $(this).attr('id');
});

Following code is working for me.

Usings:

using System.IO;
using System.Net;
using Newtonsoft.Json.Linq;

Code:

 using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (Stream responseStream = response.GetResponseStream())
                    {
                        using (StreamReader responseReader = new StreamReader(responseStream))
                        {
                            string json = responseReader.ReadToEnd();
                            string data = JObject.Parse(json)["id"].ToString();
                        }
                    }
                }

//json = {"kind": "ALL", "id": "1221455", "longUrl": "NewURL"}

From performance point of view if two lists contain number of elements that differ significantly, you can try such approach (using conditional operator ?:):

1.First you need to declare a converter:

Converter<string, int> del = delegate(string s) { return Int32.Parse(s); };

2.Then you use a conditional operator:

var r = data1.Count > data2.Count ?
 data2.ConvertAll<int>(del).Intersect(data1) :
 data1.Select(v => v.ToString()).Intersect(data2).ToList<string>().ConvertAll<int>(del);

You convert elements of shorter list to match the type of longer list. Imagine an execution speed if your first set contains 1000 elements and second only 10 (or opposite as it doesn't matter) ;-)

As you want to have a result as List, in a last line you convert the result (only result) back to int.

Aggregate can also be used for same.

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";
string joinedString = test.Aggregate((prev, current) => prev + " " + current);

Yes, it is possible to save the configuration - but it pretty much depends on the way you choose to do it. Let me describe the technical differences so you can understand the options you have:

First, you need to distinguish, whether you want to use applicationSettings or AppSettings in your *.exe.config(aka App.config in Visual Studio) file - there are fundamental differences, being described here.

Both provide different ways of saving changes:

• The AppSettings allow you to read and write directly into the config file (via config.Save(ConfigurationSaveMode.Modified);, where config is defined as config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);).
  
  
• The applicationSettings allow to read, but if you write changes (via Properties.Settings.Default.Save();) it will be written on a per-user basis, stored in a special place (e.g. C:\Documents and Settings\USERID\Local Settings\Application Data\FIRMNAME\WindowsFormsTestApplicati_Url_tdq2oylz33rzq00sxhvxucu5edw2oghw\1.0.0.0). As Hans Passant mentioned in his answer, this is because a user usually has restricted rights to Program Files and cannot write to it without invoking the UAC prompt. A disadvantage is if you're adding configuration keys in the future you need to synchronize them with every user profile.
  

Note: As mentioned in the question, there is a 3rd option: If you treat the configuration file as XML document, you can load, modify and save it by using the System.Xml.Linq.XDocument class. It is not required to use a custom XML file, you can read the existing config file; for querying elements, you can even use Linq queries. I have given an example here, check out the function GetApplicationSetting there in the answer.

If you require encryption to protect your values, check out this answer.

just set data-trigger="focus click"

There is a limit, yes. See ulimit.

Also you need to consider the TIMED_WAIT state. Once a TCP socket is closed (by default) the port remains occupied in TIMED_WAIT status for 2 minutes. This value is tunable. This will also "run you out of sockets" even though they are closed.

Run netstat to see the TIMED_WAIT stuff in action.

P.S. The reason for TIMED_WAIT is to handle the case of packets arriving after the socket is closed. This can happen because packets are delayed or the other side just doesn't know that the socket has been closed yet. This allows the OS to silently drop those packets without a chance of "infecting" a different, unrelated socket connection.

Use commons-io IOUtils.toByteArray(URL):

String url = "http://localhost:8080/images/anImage.jpg";
byte[] fileContent = IOUtils.toByteArray(new URL(url));

Maven dependency:

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.6</version>
</dependency>

This won't solve your problem, but if you only needed lat/long data for these addresses, the Google Maps API will parse non-formatted addresses pretty well.

Basically you have two ways to iterate over all elements:

1. Using recursion (the most common way I think):

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
        .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));
    doSomething(document.getDocumentElement());
}

public static void doSomething(Node node) {
    // do something with the current node instead of System.out
    System.out.println(node.getNodeName());

    NodeList nodeList = node.getChildNodes();
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentNode = nodeList.item(i);
        if (currentNode.getNodeType() == Node.ELEMENT_NODE) {
            //calls this method for all the children which is Element
            doSomething(currentNode);
        }
    }
}

2. Avoiding recursion using getElementsByTagName() method with * as parameter:

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
            .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));

    NodeList nodeList = document.getElementsByTagName("*");
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node node = nodeList.item(i);
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            // do something with the current element
            System.out.println(node.getNodeName());
        }
    }
}

I think these ways are both efficient.
Hope this helps.

You used %H (24 hour format) instead of %I (12 hour format).

If you're only running the commands in one shot then you can just use subprocess.check_output convenience function:

def subprocess_cmd(command):
    output = subprocess.check_output(command, shell=True)
    print output

In my case, I was getting this error when I serve the app, not when testing. I didn't realise I had a different configuration setting in my tsconfig.app.json file.

I previously had this:

{
  ...
  "include": [
    "src/**/*.ts"
  ]
}

It was including all my .spec.ts files when serving the app. I changed the include property toexclude` and added a regex to exclude all test files like this:

{
  ...
  "exclude": [
    "**/*.spec.ts",
    "**/__mocks__"
  ]
}

Now it works as expected.

Sometimes You just open too much applications in Windows and make the gradle have no enough memory to start the daemon process.So when you come across with this situation,you can just close some applications such as Chrome and so on. Then restart your android studio.

Hope this will work:

// create activity indicator 
UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] 
    initWithFrame:CGRectMake(0.0f, 0.0f, 20.0f, 20.0f)];
[activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhite];

...
 [self.view addSubview:activityIndicator];
// release it
[activityIndicator release];

I haven't seen someone mention this method but document.createElementNS() is helpful in this instance.

You can create the elements using vanilla Javascript as normal DOM nodes with the correct namespace and then jQuery-ify them from there. Like so:

var svg = document.createElementNS('http://www.w3.org/2000/svg', 'svg'),
    circle = document.createElementNS('http://www.w3.org/2000/svg', 'circle');

var $circle = $(circle).attr({ //All your attributes });

$(svg).append($circle);

The only down side is that you have to create each SVG element with the right namespace individually or it won't work.

    document.getElementById("id").innerHTML='<object type="text/html" data="x.html"></object>';

I think this might be useful... I love example code :)

var fs = require('fs');

var myData = {
  name:'test',
  version:'1.0'
}

var outputFilename = '/tmp/my.json';

fs.writeFile(outputFilename, JSON.stringify(myData, null, 4), function(err) {
    if(err) {
      console.log(err);
    } else {
      console.log("JSON saved to " + outputFilename);
    }
}); 

You need to enqueue the script bootstrap.js or bootstrap.min.js. I had the same problem with bootstrap 4.5.3 and the menu worked when I enqueued one of the above scripts. It can be either.

For people don't care about jquery use, here is a short way without using any id

<label> userAvatar :
  <input type="range" name="userAvatar" min="1" max="100" value="1"
         onchange="$('~ output', this).val(value)" 
         oninput="$('~ output', this).val(value)">
  <output>1</output>
</label>

Just posting because the root cause for my case has not been described her.

In my case the problem was that "assets/js/fuelux/treeview/fuelux.min.js" was adding a constructor .datepicker(), so that was overriding the assets/js/datetime/bootstrap-datepicker.js

just moving the

to be just before the $('.date-picker') solved my problem.

Razorsql can handle many kinds of databases.

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

You were on the right track with your "ng-keydown" attribute on the input, but you missed a simple step. Just because you put the ng-keydown attribute there, doesn't mean angular knows what to do with it. That's where "directives" come into play. You used the attribute correctly, but you now need to write a directive that will tell angular what to do when it sees that attribute on an html element.

The following is an example of how you would do that. We'll rename the directive from ng-keydown to on-keydown (to avoid breaking the "best practice" found here):

var mod = angular.module('mydirectives');
mod.directive('onKeydown', function() {
    return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
             // this next line will convert the string
             // function name into an actual function
             var functionToCall = scope.$eval(attrs.ngKeydown);
             elem.on('keydown', function(e){
                  // on the keydown event, call my function
                  // and pass it the keycode of the key
                  // that was pressed
                  // ex: if ENTER was pressed, e.which == 13
                  functionToCall(e.which);
             });
        }
    };
});

The directive simple tells angular that when it sees an HTML attribute called "ng-keydown", it should listen to the element that has that attribute and call whatever function is passed to it. In the html you would have the following:

<input type="text" on-keydown="onKeydown">

And then in your controller (just like you already had), you would add a function to your controller's scope that is called "onKeydown", like so:

$scope.onKeydown = function(keycode){
    // do something with the keycode
}

Hopefully that helps either you or someone else who wants to know

you can use as.matrix as below:

output <- as.matrix(z)

If you are using Visual S2019, Create a new local branch as shown in following, and then push the changes to the repo.

One can rename indexes the same way:

alter index owner.index_name rename to new_name;

On *nix check nm. On windows use the program Dependency Walker

Look in TomcatDirectory/logs/catalina.out for the logs. If the logs are too long, delete the catalina.out file and rerun the app.

No, the IEnumerable doesn't support adding items to it.

Your 'alternative' is:

var myList = new List(items);
myList.Add(otherItem);

In modern browsers you do not need JQuery for this. Instead use

document.querySelectorAll('option:checked')

Or specify any DOM element instead of document

You should be aware that you should avoid file I/O from within Linux kernel when possible. The main idea is to go "one level deeper" and call VFS level functions instead of the syscall handler directly:

Includes:

#include <linux/fs.h>
#include <asm/segment.h>
#include <asm/uaccess.h>
#include <linux/buffer_head.h>

Opening a file (similar to open):

struct file *file_open(const char *path, int flags, int rights) 
{
    struct file *filp = NULL;
    mm_segment_t oldfs;
    int err = 0;

    oldfs = get_fs();
    set_fs(get_ds());
    filp = filp_open(path, flags, rights);
    set_fs(oldfs);
    if (IS_ERR(filp)) {
        err = PTR_ERR(filp);
        return NULL;
    }
    return filp;
}

Close a file (similar to close):

void file_close(struct file *file) 
{
    filp_close(file, NULL);
}

Reading data from a file (similar to pread):

int file_read(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_read(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}   

Writing data to a file (similar to pwrite):

int file_write(struct file *file, unsigned long long offset, unsigned char *data, unsigned int size) 
{
    mm_segment_t oldfs;
    int ret;

    oldfs = get_fs();
    set_fs(get_ds());

    ret = vfs_write(file, data, size, &offset);

    set_fs(oldfs);
    return ret;
}

Syncing changes a file (similar to fsync):

int file_sync(struct file *file) 
{
    vfs_fsync(file, 0);
    return 0;
}

[Edit] Originally, I proposed using file_fsync, which is gone in newer kernel versions. Thanks to the poor guy suggesting the change, but whose change was rejected. The edit was rejected before I could review it.

Swanand's answer is great.

if you are using FactoryGirl, you can use its build method to generate the attribute hash without the key id. e.g.

build(:post).attributes

I figured it out. Need to use echo in PHP instead of return.

<?php 
  $output = some_function();
  echo $output;
?> 

And the jQ:

success: function(data) {
  doSomething(data);
}

This is the solution if your file has more . (dots) in the name.

<script type="text/javascript">var x = "file1.asdf.txt";
var y = x.split(".");
alert(y[(y.length)-1]);</script>

You may also consider using line.rstrip() to remove the whitespaces at the end of your line.

For Laravel 5.5+

Controller:

return redirect()->back()->with('success', 'your message here');

Blade:

@if (Session::has('success'))
    <div class="alert alert-success">
        <ul>
            <li>{{ Session::get('success') }}</li>
        </ul>
    </div>
@endif

use the Date.toLocaleString() method :

new Date(dateString).toLocaleString('en-us', {weekday:'long'})

What are you doing: (I am using bytes instead of in for better reading)

You start with int *ap and so on, so your (your computers) memory looks like this:

-------------- memory used by some one else --------
000: ?
001: ?
...
098: ?
099: ?
-------------- your memory  --------
100: something          <- here is *ap
101: 41                 <- here starts a[] 
102: 42
103: 43
104: 44
105: 45
106: something          <- here waits x

lets take a look waht happens when (print short cut for ...print("$d", ...)

print a[0]  -> 41   //no surprise
print a     -> 101  // because a points to the start of the array
print *a    -> 41   // again the first element of array
print a+1   -> guess? 102
print *(a+1)    -> whats behind 102? 42 (we all love this number)

and so on, so a[0] is the same as *a, a[1] = *(a+1), ....

a[n] just reads easier.

now, what happens at line 9?

ap=a[4] // we know a[4]=*(a+4) somehow *105 ==>  45 
// warning! converting int to pointer!
-------------- your memory  --------
100: 45         <- here is *ap now 45

x = *ap;   // wow ap is 45 -> where is 45 pointing to?
-------------- memory used by some one else --------
bang!      // dont touch neighbours garden

So the "warning" is not just a warning it's a severe error.

For those not sure about which peak-finding algorithms to use in Python, here a rapid overview of the alternatives: https://github.com/MonsieurV/py-findpeaks

Wanting myself an equivalent to the MatLab findpeaks function, I've found that the detect_peaks function from Marcos Duarte is a good catch.

Pretty easy to use:

import numpy as np
from vector import vector, plot_peaks
from libs import detect_peaks
print('Detect peaks with minimum height and distance filters.')
indexes = detect_peaks.detect_peaks(vector, mph=7, mpd=2)
print('Peaks are: %s' % (indexes))

Which will give you:

echo '<a href="' . $folder_path . '">Link text</a>';

Please note that you must use the path relative to your domain and, if the folder path is outside the public htdocs directory, it will not work.

EDIT: maybe i misreaded the question; you have a file on your pc and want to insert the path on the html page, and then send it to the server?

The solution here worked for me. It's a matter of importing the library to the libs folder, then modifying the build.gradle file and then cleaning with gradlew.

Alternatively, you can use numpy underlying function:

>>> import numpy as np
>>> df = pd.DataFrame({"A": [10,20,30], "B": [20, 30, 10]})
>>> df['new_column'] = np.multiply(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

or vectorize arbitrary function in general case:

>>> def fx(x, y):
...     return x*y
...
>>> df['new_column'] = np.vectorize(fx)(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

You can also use .map() as:

var list=[];

response.data.message.map(function(value, key) {
     list.push(value);
   });

Following worked for me:
<context:property-placeholder location="file:src/resources/spring/AppController.properties"/>

Somehow "classpath:xxx" is not picking the file.

    python 3.2

    with open("d://test.txt") as f:
              k=(((i.split("\n"))[0].rstrip()).split() for i in f.readlines())
              d={}
              for i,_,v in k:
                      d.setdefault(i,[]).append(v)

I spent a lot of time looking for a solution to this problem too. Here's what i've found thus far:

If you want your users to be able to click on a button and copy some text, you may have to use Flash.

If you want your users to press Ctrl+C anywhere on the page, but always copy xyz to the clipboard, I wrote an all-JS solution in YUI3 (although it could easily be ported to other frameworks, or raw JS if you're feeling particularly self-loathing).

It involves creating a textbox off the screen which gets highlighted as soon as the user hits Ctrl/CMD. When they hit 'C' shortly after, they copy the hidden text. If they hit 'V', they get redirected to a container (of your choice) before the paste event fires.

This method can work well, because while you listen for the Ctrl/CMD keydown anywhere in the body, the 'A', 'C' or 'V' keydown listeners only attach to the hidden text box (and not the whole body). It also doesn't have to break the users expectations - you only get redirected to the hidden box if you had nothing selected to copy anyway!

Here's what i've got working on my site, but check http://at.cg/js/clipboard.js for updates if there are any:

YUI.add('clipboard', function(Y) {


// Change this to the id of the text area you would like to always paste in to:

pasteBox = Y.one('#pasteDIV');


// Make a hidden textbox somewhere off the page.

Y.one('body').append('<input id="copyBox" type="text" name="result" style="position:fixed; top:-20%;" onkeyup="pasteBox.focus()">');
copyBox = Y.one('#copyBox');


// Key bindings for Ctrl+A, Ctrl+C, Ctrl+V, etc:

// Catch Ctrl/Window/Apple keydown anywhere on the page.
Y.on('key', function(e) {
    copyData();
        //  Uncomment below alert and remove keyCodes after 'down:' to figure out keyCodes for other buttons.
        //  alert(e.keyCode);
        //  }, 'body',  'down:', Y);
}, 'body',  'down:91,224,17', Y);

// Catch V - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // Oh no! The user wants to paste, but their about to paste into the hidden #copyBox!!
    // Luckily, pastes happen on keyPress (which is why if you hold down the V you get lots of pastes), and we caught the V on keyDown (before keyPress).
    // Thus, if we're quick, we can redirect the user to the right box and they can unload their paste into the appropriate container. phew.
    pasteBox.select();
}, '#copyBox',  'down:86', Y);

// Catch A - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // User wants to select all - but he/she is in the hidden #copyBox! That wont do.. select the pasteBox instead (which is probably where they wanted to be).
    pasteBox.select();
}, '#copyBox',  'down:65', Y);



// What to do when keybindings are fired:

// User has pressed Ctrl/Meta, and is probably about to press A,C or V. If they've got nothing selected, or have selected what you want them to copy, redirect to the hidden copyBox!
function copyData() {
    var txt = '';
    // props to Sabarinathan Arthanari for sharing with the world how to get the selected text on a page, cheers mate!
        if (window.getSelection) { txt = window.getSelection(); }
        else if (document.getSelection) { txt = document.getSelection(); }
        else if (document.selection) { txt = document.selection.createRange().text; }
        else alert('Something went wrong and I have no idea why - please contact me with your browser type (Firefox, Safari, etc) and what you tried to copy and I will fix this immediately!');

    // If the user has nothing selected after pressing Ctrl/Meta, they might want to copy what you want them to copy. 
        if(txt=='') {
                copyBox.select();
        }
    // They also might have manually selected what you wanted them to copy! How unnecessary! Maybe now is the time to tell them how silly they are..?!
        else if (txt == copyBox.get('value')) {
        alert('This site uses advanced copy/paste technology, possibly from the future.\n \nYou do not need to select things manually - just press Ctrl+C! \n \n(Ctrl+V will always paste to the main box too.)');
                copyBox.select();
        } else {
                // They also might have selected something completely different! If so, let them. It's only fair.
        }
}
});

Hope someone else finds this useful :]

I not expert in MySQL but you probably should look on triggers e.g. BEFORE INSERT. In the trigger you can run select query on your original table and if it found something just update the row 'logins' instead of inserting new values. But all this depends on version of MySQL you running.

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

If you are using Android Studio 3.0 or later version then follow these steps.

1. Click View > Tool Windows > Device File Explorer.
2. Expand /data/data/[package-name] nodes.

You can only expand packages which runs in debug mode on non-rooted device.

You should be checking the root directory and not the app directory.

Look in $ROOT/storage/laravel.log not app/storage/laravel.log, where root is the top directory of the project.

I also faced similar issues when tried to do ng serve. I was able to resolve it as below.
Note:

C:\Windows\system32> is on windows command prompt
C:\apps\workspace\testProj>  is on VS code Terminal (can also be doable in another command prompt)

Following are the steps which I used to resolve this.

Step1. Verify the cli version installed on command prompt (will be Angular CLI global version)

C:\Windows\system32>ng --version

Angular CLI: 8.3.13

If cli was installed earlier, it shows the global cli version.

If cli was not installed, we may get the error
ng is not recognized as an internal or external command

a. (Optional Step) Install Angular CLI global version

C:\Windows\system32>npm install -g @angular/cli
C:\Windows\system32>npm install -g @angular-cli/latest

b. Check version again

C:\Windows\system32>ng --version
Angular CLI: 8.3.13

Step2. Verify the local cli version installed on your angular project(VS code ide or command prompt cd'd to your project project)

C:\apps\workspace\testProj>ng --version
Angular CLI: 7.3.8

Note: Clearly versions are not in sync. Do the following in your angular project

C:\apps\workspace\testProj>ng update @angular/cli        -> important to sync with global cli version

Note: If upgrade donot work using above command (ref: How to upgrade Angular CLI to the latest version) On command prompt, uninstall global angular cli, clean the cache and reinstall the cli

C:\Windows\system32>npm uninstall -g angular-cli
C:\Windows\system32>npm cache clean or npm cache verify #(if npm > 5)
C:\Windows\system32>npm install -g @angular/cli@latest

Now update your local project version, because cli version of your local project is having higher priority than global one when you try to execute your project.

C:\apps\workspace\testProj>rm -rf node_modules
C:\apps\workspace\testProj>npm uninstall --save-dev angular-cli
C:\apps\workspace\testProj>npm install --save-dev @angular/cli@latest
C:\apps\workspace\testProj>npm install
C:\apps\workspace\testProj>ng update @angular/cli

Step3. Verify if local project cli version now in sync with global one

C:\Windows\system32>ng --version
Angular CLI: 8.3.13

C:\apps\workspace\testProj>ng --version
Angular CLI: 8.3.13

Step4.. Revalidate on the project

C:\apps\workspace\testProj>ng serve

Should work now

As error message said your application has no permissions to read from the directory. It can be the case when you created the directory as one user and run script as another user.

You can use an extension method like this:

internal static class ArrayExt
{
    public static IEnumerable<int> Indices(this Array array, int dimension)
    {
        for (var i = array.GetLowerBound(dimension); i <= array.GetUpperBound(dimension); i++)
        {
            yield return i;
        }
    }
}

And then:

int[,] array = { { 1, 2, 3 }, { 4, 5, 6 } };
foreach (var i in array.Indices(0))
{
    foreach (var j in array.Indices(1))
    {
        Console.Write(array[i, j]);
    }

    Console.WriteLine();
}

It will be a bit slower than using for loops but probably not an issue in most cases. Not sure if it makes things more readable.

Note that c# arrays can be other than zero-based so you can use a for loop like this:

int[,] array = { { 1, 2, 3 }, { 4, 5, 6 } };
for (var i = array.GetLowerBound(0); i <= array.GetUpperBound(0); i++)
{
    for (var j= array.GetLowerBound(1); j <= array.GetUpperBound(1); j++)
    {
        Console.Write(array[i, j]);
    }

    Console.WriteLine();
}

Hey I have answered this question here. Basically, you need to override

public Object instantiateItem(ViewGroup container, int position)

method of FragmentStatePagerAdapter.

To add a column I just had to follow these steps :

1. rails generate migration add_fieldname_to_tablename fieldname:string

   Alternative

   rails generate migration addFieldnameToTablename

   Once the migration is generated, then edit the migration and define all the attributes you want that column added to have.

   Note: Table names in Rails are always plural (to match DB conventions). Example using one of the steps mentioned previously-

   rails generate migration addEmailToUsers

2. rake db:migrate

Or

1. You can change the schema in from db/schema.rb, Add the columns you want in the SQL query.

2. Run this command: rake db:schema:load

   Warning/Note

   Bear in mind that, running rake db:schema:load automatically wipes all data in your tables.

Edge has dropped all support for plugins. This means that Java, ActiveX, Silverlight, and other plugins are no longer supported. For this reason Microsoft has included Internet Explorer 11, which does support these plugins, with non-mobile versions of Windows 10. If you are running Windows 10 and need plugin support Edge is not an option, but IE 11 is.

Rather simple:

Key = i.ToString("D2");

D stands for "decimal number", 2 for the number of digits to print.

If you’re not opposed to jquery, this can be done in one line:

jQuery 1.7+

$("#myEl").off()

jQuery < 1.7

$('#myEl').replaceWith($('#myEl').clone());

Here’s an example:

This change worked for me:

// The size returned by CGImageGetWidth(imgRef) & CGImageGetHeight(imgRef) is incorrect as it doesn't respect the image orientation!
// CGImageRef imgRef = [image CGImage];
// CGFloat width = CGImageGetWidth(imgRef);
// CGFloat height = CGImageGetHeight(imgRef);
//
// This returns the actual width and height of the photo (and hence solves the problem
CGFloat width = image.size.width; 
CGFloat height = image.size.height;
CGRect bounds = CGRectMake(0, 0, width, height);

Eclipse has limit of 32000 characters per line. If you have, for example JSONObject, which you want to log into console, you won't succeed. You can't handle this with the checkbox. Tested

Please follow these steps carefully to enable it.

1) create Spring Boot project with SB V1.3 and add "Devtools" (1*) to dependencies

2) invoke Help->Find Action... and type "Registry", in the dialog search for "automake" and enable the entry "compiler.automake.allow.when.app.running", close dialog

3) enable background compilation in Settings->Build, Execution, Deployment->Compiler "Make project automatically"

4) open Spring Boot run config, you should get warning message if everything is configured correctly

5) Run your app, change your classes on-the-fly

The @ operator calls the array's __matmul__ method, not dot. This method is also present in the API as the function np.matmul.

>>> a = np.random.rand(8,13,13)
>>> b = np.random.rand(8,13,13)
>>> np.matmul(a, b).shape
(8, 13, 13)

From the documentation:

matmul differs from dot in two important ways.

• Multiplication by scalars is not allowed.
• Stacks of matrices are broadcast together as if the matrices were elements.

The last point makes it clear that dot and matmul methods behave differently when passed 3D (or higher dimensional) arrays. Quoting from the documentation some more:

For matmul:

If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly.

For np.dot:

For 2-D arrays it is equivalent to matrix multiplication, and for 1-D arrays to inner product of vectors (without complex conjugation). For N dimensions it is a sum product over the last axis of a and the second-to-last of b

ZXing is an open source project that can detect and parse a number of different barcodes. It can also generate QR-codes. (Only QR-codes, though).

There are a number of variants for different languages: ActionScript, Android (java), C++, C#, IPhone (Obj C), Java ME, Java SE, JRuby, JSP. Support for generating QR-codes comes with some of those: ActionScript, Android, C# and the Java variants.

Upload a file

Upload a file to a SharePoint site (including SharePoint Online) using File.SaveBinaryDirect Method:

using (var clientContext = new ClientContext(url))
{
     using (var fs = new FileStream(fileName, FileMode.Open))
     {
         var fi = new FileInfo(fileName);
         var list = clientContext.Web.Lists.GetByTitle(listTitle);
         clientContext.Load(list.RootFolder);
         clientContext.ExecuteQuery();
         var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);

         Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, fileUrl, fs, true);
     }
}

Download file

Download file from a SharePoint site (including SharePoint Online) using File.OpenBinaryDirect Method:

using (var clientContext = new ClientContext(url))
{

     var list = clientContext.Web.Lists.GetByTitle(listTitle);
     var listItem = list.GetItemById(listItemId);
     clientContext.Load(list);
     clientContext.Load(listItem, i => i.File);
     clientContext.ExecuteQuery();

     var fileRef = listItem.File.ServerRelativeUrl;
     var fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, fileRef);
     var fileName = Path.Combine(filePath,(string)listItem.File.Name);
     using (var fileStream = System.IO.File.Create(fileName))
     {                  
          fileInfo.Stream.CopyTo(fileStream);
     }
}

With Swift you don't need anymore to check the equality with isEqualToString

You can now use ==

Example:

let x = "hello"
let y = "hello"
let isEqual = (x == y)

now isEqual is true.

This can be done using the unique function in ufp.path module.

import ufp.path
ufp.path.unique('./test.ext')

if current path exists 'test.ext' file. ufp.path.unique function return './test (d1).ext'.

If you send the form empty, $_POST['mail'] will still be sent, but the value is empty. To check if the field is empty you need to check

if(isset($_POST["mail"]) && trim($_POST["mail"]) != "") { .. }

\s means "one space", and \s+ means "one or more spaces".

But, because you're using the /g flag (replace all occurrences) and replacing with the empty string, your two expressions have the same effect.

I (being people myself) wrote this statement because I wanted to detect the key which the user typed on the keyboard across different browsers.

In firefox for example, characters have > 0 charCode and 0 keyCode, and keys such as arrows & backspace have > 0 keyCode and 0 charCode.

However, using this statement can be problematic as "collisions" are possible. For example, if you want to distinguish between the Delete and the Period keys, this won't work, as the Delete has keyCode = 46 and the Period has charCode = 46.

or... you can just put some style like this.

.panel-title a.collapsed {
     background: url(../img/arrow_right.png) center right no-repeat;
}
.panel-title a {
     background: url(../img/arrow_down.png) center right no-repeat;
}

Here is a solution in Java a bit lengthy but works..

public static int getHeight (Node root){
    int lheight = 0, rheight = 0;
    if(root==null) {
        return 0;
    }
    else {
        if(root.left != null) {
            lheight = 1 + getHeight(root.left);
            System.out.println("lheight" + " " + lheight);
        }
        if (root.right != null) {
            rheight = 1+ getHeight(root.right);
            System.out.println("rheight" + " " + rheight);
        }
        if(root != null && root.left == null && root.right == null) {
            lheight += 1; 
            rheight += 1;
        }

    }
    return Math.max(lheight, rheight);
    }

The proper way is to manually put the repository in the right place. Once the repository is there, you can use go get -u to update the package and go install to install it. A package named

github.com/secmask/awserver-go

goes into

$GOPATH/src/github.com/secmask/awserver-go

The commands you type are:

cd $GOPATH/src/github.com/secmask
git clone [email protected]:secmask/awserver-go.git

There are multiple versions of the echo command, with different behaviors. Apparently the shell used for your script uses a version that doesn't recognize -n.

The printf command has much more consistent behavior. echo is fine for simple things like echo hello, but I suggest using printf for anything more complicated.

What system are you on, and what shell does your script use?

The whole reason you have a special Interface type-category in addition to abstract base classes in C#/Java is because C#/Java do not support multiple inheritance.

C++ supports multiple inheritance, and so a special type isn't needed. An abstract base class with no non-abstract (pure virtual) methods is functionally equivalent to a C#/Java interface.

The problem is that your ApplicationUser inherits from IdentityUser, which is defined like this:

IdentityUser : IdentityUser<string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUser
....
public virtual ICollection<TRole> Roles { get; private set; }
public virtual ICollection<TClaim> Claims { get; private set; }
public virtual ICollection<TLogin> Logins { get; private set; }

and their primary keys are mapped in the method OnModelCreating of the class IdentityDbContext:

modelBuilder.Entity<TUserRole>()
            .HasKey(r => new {r.UserId, r.RoleId})
            .ToTable("AspNetUserRoles");

modelBuilder.Entity<TUserLogin>()
            .HasKey(l => new {l.LoginProvider, l.ProviderKey, l.UserId})
            .ToTable("AspNetUserLogins");

and as your DXContext doesn't derive from it, those keys don't get defined.

If you dig into the sources of Microsoft.AspNet.Identity.EntityFramework, you will understand everything.

I came across this situation some time ago, and I found three possible solutions (maybe there are more):

1. Use separate DbContexts against two different databases or the same database but different tables.
2. Merge your DXContext with ApplicationDbContext and use one database.
3. Use separate DbContexts against the same table and manage their migrations accordingly.

Option 1: See update the bottom.

Option 2: You will end up with a DbContext like this one:

public class DXContext : IdentityDbContext<User, Role,
    int, UserLogin, UserRole, UserClaim>//: DbContext
{
    public DXContext()
        : base("name=DXContext")
    {
        Database.SetInitializer<DXContext>(null);// Remove default initializer
        Configuration.ProxyCreationEnabled = false;
        Configuration.LazyLoadingEnabled = false;
    }

    public static DXContext Create()
    {
        return new DXContext();
    }

    //Identity and Authorization
    public DbSet<UserLogin> UserLogins { get; set; }
    public DbSet<UserClaim> UserClaims { get; set; }
    public DbSet<UserRole> UserRoles { get; set; }
    
    // ... your custom DbSets
    public DbSet<RoleOperation> RoleOperations { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();

        // Configure Asp Net Identity Tables
        modelBuilder.Entity<User>().ToTable("User");
        modelBuilder.Entity<User>().Property(u => u.PasswordHash).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.Stamp).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.PhoneNumber).HasMaxLength(50);

        modelBuilder.Entity<Role>().ToTable("Role");
        modelBuilder.Entity<UserRole>().ToTable("UserRole");
        modelBuilder.Entity<UserLogin>().ToTable("UserLogin");
        modelBuilder.Entity<UserClaim>().ToTable("UserClaim");
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimType).HasMaxLength(150);
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimValue).HasMaxLength(500);
    }
}

Option 3: You will have one DbContext equal to the option 2. Let's name it IdentityContext. And you will have another DbContext called DXContext:

public class DXContext : DbContext
{        
    public DXContext()
        : base("name=DXContext") // connection string in the application configuration file.
    {
        Database.SetInitializer<DXContext>(null); // Remove default initializer
        Configuration.LazyLoadingEnabled = false;
        Configuration.ProxyCreationEnabled = false;
    }

    // Domain Model
    public DbSet<User> Users { get; set; }
    // ... other custom DbSets
    
    public static DXContext Create()
    {
        return new DXContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        // IMPORTANT: we are mapping the entity User to the same table as the entity ApplicationUser
        modelBuilder.Entity<User>().ToTable("User"); 
    }

    public DbQuery<T> Query<T>() where T : class
    {
        return Set<T>().AsNoTracking();
    }
}

where User is:

public class User
{
    public int Id { get; set; }

    [Required, StringLength(100)]
    public string Name { get; set; }

    [Required, StringLength(128)]
    public string SomeOtherColumn { get; set; }
}

With this solution, I'm mapping the entity User to the same table as the entity ApplicationUser.

Then, using Code First Migrations you'll need to generate the migrations for the IdentityContext and THEN for the DXContext, following this great post from Shailendra Chauhan: Code First Migrations with Multiple Data Contexts

You'll have to modify the migration generated for DXContext. Something like this depending on which properties are shared between ApplicationUser and User:

        //CreateTable(
        //    "dbo.User",
        //    c => new
        //        {
        //            Id = c.Int(nullable: false, identity: true),
        //            Name = c.String(nullable: false, maxLength: 100),
        //            SomeOtherColumn = c.String(nullable: false, maxLength: 128),
        //        })
        //    .PrimaryKey(t => t.Id);
        AddColumn("dbo.User", "SomeOtherColumn", c => c.String(nullable: false, maxLength: 128));

and then running the migrations in order (first the Identity migrations) from the global.asax or any other place of your application using this custom class:

public static class DXDatabaseMigrator
{
    public static string ExecuteMigrations()
    {
        return string.Format("Identity migrations: {0}. DX migrations: {1}.", ExecuteIdentityMigrations(),
            ExecuteDXMigrations());
    }

    private static string ExecuteIdentityMigrations()
    {
        IdentityMigrationConfiguration configuration = new IdentityMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string ExecuteDXMigrations()
    {
        DXMigrationConfiguration configuration = new DXMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string RunMigrations(DbMigrationsConfiguration configuration)
    {
        List<string> pendingMigrations;
        try
        {
            DbMigrator migrator = new DbMigrator(configuration);
            pendingMigrations = migrator.GetPendingMigrations().ToList(); // Just to be able to log which migrations were executed

            if (pendingMigrations.Any())                
                    migrator.Update();     
        }
        catch (Exception e)
        {
            ExceptionManager.LogException(e);
            return e.Message;
        }
        return !pendingMigrations.Any() ? "None" : string.Join(", ", pendingMigrations);
    }
}

This way, my n-tier cross-cutting entities don't end up inheriting from AspNetIdentity classes, and therefore I don't have to import this framework in every project where I use them.

Sorry for the extensive post. I hope it could offer some guidance on this. I have already used options 2 and 3 in production environments.

UPDATE: Expand Option 1

For the last two projects I have used the 1st option: having an AspNetUser class that derives from IdentityUser, and a separate custom class called AppUser. In my case, the DbContexts are IdentityContext and DomainContext respectively. And I defined the Id of the AppUser like this:

public class AppUser : TrackableEntity
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
    // This Id is equal to the Id in the AspNetUser table and it's manually set.
    public override int Id { get; set; }

(TrackableEntity is the custom abstract base class that I use in the overridden SaveChanges method of my DomainContext context)

I first create the AspNetUser and then the AppUser. The drawback with this approach is that you have ensured that your "CreateUser" functionality is transactional (remember that there will be two DbContexts calling SaveChanges separately). Using TransactionScope didn't work for me for some reason, so I ended up doing something ugly but that works for me:

        IdentityResult identityResult = UserManager.Create(aspNetUser, model.Password);

        if (!identityResult.Succeeded)
            throw new TechnicalException("User creation didn't succeed", new LogObjectException(result));

        AppUser appUser;
        try
        {
            appUser = RegisterInAppUserTable(model, aspNetUser);
        }
        catch (Exception)
        {
            // Roll back
            UserManager.Delete(aspNetUser);
            throw;
        }

(Please, if somebody comes with a better way of doing this part I appreciate commenting or proposing an edit to this answer)

The benefits are that you don't have to modify the migrations and you can use any crazy inheritance hierarchy over the AppUser without messing with the AspNetUser. And actually, I use Automatic Migrations for my IdentityContext (the context that derives from IdentityDbContext):

public sealed class IdentityMigrationConfiguration : DbMigrationsConfiguration<IdentityContext>
{
    public IdentityMigrationConfiguration()
    {
        AutomaticMigrationsEnabled = true;
        AutomaticMigrationDataLossAllowed = false;
    }

    protected override void Seed(IdentityContext context)
    {
    }
}

This approach also has the benefit of avoiding to have your n-tier cross-cutting entities inheriting from AspNetIdentity classes.

The keyword simply pops a frame from the call stack returning the control to the line following the function call.

Following on from jpw it might be good to encapsulate his solution in a small subroutine to save on having lots of lines of code:

Private Sub CommandButton1_Click()
Dim i As Integer
Dim a As Integer
a = 15

I prefer this small method.

function getAgeFromBirthday(birthday) {
    if(birthday){
      var totalMonths = moment().diff(birthday, 'months');
      var years = parseInt(totalMonths / 12);
      var months = totalMonths % 12;
        if(months !== 0){
           return parseFloat(years + '.' + months);
         }
    return years;
      }
    return null;
}

You can also pull the latest commit and just undo until the commit you desire:

git pull origin master
git reset --hard HEAD~1

Replace master with your desired branch.

Use git log to see to which commit you would like to revert:

git log

Personally, this has worked for me better.

Basically, what this does is pulls the latest commit, and you manually revert commits one by one. Use git log in order to see commit history.

Good points: Works as advertised. You don't have to use commit hash or pull unneeded branches.

Bad points: You need to revert commits on by one.

WARNING: Commit/stash all your local changes, because with --hard you are going to lose them. Use at your own risk!

Example-

For cells containing the values between 21-31, the formula is:

=COUNTIF(M$7:M$83,">21")-COUNTIF(M$7:M$83,">31")

If you want a minimum of 4 characters, for instance,

System.out.println(String.format("%4d", 5));
// Results in "   5", minimum of 4 characters

i Did it, just follow this tutorial. helps a lot

If this seems inconsistent from machine to machine, have you made sure that some 3rd party app like virus scan isn't intercepting something?

Agree with Nick. Here is more elaborated code.

#count=0
for idx, item in enumerate(list):
    print item
    #count +=1
    #if count % 10 == 0:
    if (idx+1) % 10 == 0:
        print 'did ten'

I have commented out the count variable in your code.

The method arrayList.size() returns the number of items in the list - so if the index is greater than or equal to the size(), it doesn't exist.

if(index >= myList.size()){
  //index not exists
}else{
 // index exists
}

When mysql was installed with Homebrew, the following command did the trick for me:

1) Install 'body-parser' from npm.

2) Then in your app.ts

var bodyParser = require('body-parser');

3) then you need to write

app.use(bodyParser.json())

in app.ts module

4) keep in mind that you include

app.use(bodyParser.json())

in the top or before any module declaration.

Ex:

app.use(bodyParser.json())
app.use('/user',user);

5) Then use

var postdata = req.body;

**Use Spread Operators| ES6 **

let datesVar = [ 2017-10-26T03:37:10.876Z,

  2017-10-23T03:37:10.876Z,
  2015-10-23T03:37:10.876Z ]

Math.min(...datesVar);

That will give the minimum date from the array.

Its shorthand Math.min.apply(null, ArrayOfdates);

One reason to use an explicite Platform.runLater() could be that you bound a property in the ui to a service (result) property. So if you update the bound service property, you have to do this via runLater():

In UI thread also known as the JavaFX Application thread:

...    
listView.itemsProperty().bind(myListService.resultProperty());
...

in Service implementation (background worker):

...
Platform.runLater(() -> result.add("Element " + finalI));

To get left and right tabs (now also with sideways) support for Bootstrap 3, bootstrap-vertical-tabs component can be used.

https://github.com/dbtek/bootstrap-vertical-tabs

from datetime import datetime, timedelta

nine_hours_from_now = datetime.now() + timedelta(hours=9)
#datetime.datetime(2012, 12, 3, 23, 24, 31, 774118)

And then use string formatting to get the relevant pieces:

>>> '{:%H:%M:%S}'.format(nine_hours_from_now)
'23:24:31'

If you're only formatting the datetime then you can use:

>>> format(nine_hours_from_now, '%H:%M:%S')
'23:24:31'

Or, as @eumiro has pointed out in comments - strftime

We can use TRUNC function in Oracle DB. Here is an example.

SELECT TRUNC(TO_DATE('01 Jan 2018 08:00:00','DD-MON-YYYY HH24:MI:SS')) FROM DUAL

Output: 1/1/2018

You are passing into the JSONObject constructor an instance of a StringBuilder class.

This is using the JSONObject(Object) constructor, not the JSONObject(String) one.

Your code should be:

JSONObject jsonObj = new JSONObject(jsonString.toString());

Berkelium is a C++ tool for making chrome embeddable.

AwesomiumDotNet is a wrapper around both Berkelium and Awesomium

BTW, the link here to Awesomium appears to be more current.

if what you need is the width and height of the frame in the circle, why not pass the DrawFrame width and height into the DrawCircle constructor:

public DrawCircle(int w, int h){
    this.w = w;
    this.h = h;
    diBig = 300;
    diSmall = 10;
    maxRad = (diBig/2) - diSmall;
    xSq = 50;
    ySq = 50;
    xPoint = 200;
    yPoint = 200;
}

you could also add a couple new methods to DrawCircle:

public void setWidth(int w) 
   this.w = w;

public void setHeight(int h)
   this.h = h; 

or even:

public void setDimension(Dimension d) {
   w=d.width;
   h=d.height;
}

if you go down this route, you will need to update DrawFrame to make a local var of the DrawCircle on which to call these methods.

edit:

when changing the DrawCircle constructor as described at the top of my post, dont forget to add the width and height to the call to the constructor in DrawFrame:

public class DrawFrame extends JFrame {
 public DrawFrame() {
    int width = 400;
    int height = 400;

    setTitle("Frame");
    setSize(width, height);

    addWindowListener(new WindowAdapter()
    {
            public void windowClosing(WindowEvent e)
            {
                    System.exit(0);
            }
    });

    Container contentPane = getContentPane();
    //pass in the width and height to the DrawCircle contstructor
    contentPane.add(new DrawCircle(width, height));
 }
}

Although others have already clarified that there is no direct goto equivalent in bash (and provided the closest alternatives such as functions, loops, and break), I would like to illustrate how using a loop plus break can simulate a specific type of goto statement.

The situation where I find this the most useful is when I need to return to the beginning of a section of code if certain conditions are not met. In the example below, the while loop will run forever until ping stops dropping packets to a test IP.

#!/bin/bash

TestIP="8.8.8.8"

# Loop forever (until break is issued)
while true; do

    # Do a simple test for Internet connectivity
    PacketLoss=$(ping "$TestIP" -c 2 | grep -Eo "[0-9]+% packet loss" | grep -Eo "^[0-9]")

    # Exit the loop if ping is no longer dropping packets
    if [ "$PacketLoss" == 0 ]; then
        echo "Connection restored"
        break
    else
        echo "No connectivity"
    fi
done

The ** syntax tells Python to collect keyword arguments into a dictionary. The save2 is passing it down as a non-keyword argument (a dictionary object). The openX is not seeing any keyword arguments so the **args doesn't get used. It's instead getting a third non-keyword argument (the dictionary). To fix that change the definition of the openX function.

def openX(filename, mode, kwargs):
    pass

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

You will need to add a "kernel" for it. Run your enviroment:

>activate tensorflow

Then add a kernel by command (after --name should follow your env. with tensorflow):

>python -m ipykernel install --user --name tensorflow --display-name "TensorFlow-GPU"

After that run jupyter notebook from your tensorflow env.

>jupyter notebook

And then you will see the following enter image description here

Click on it and then in the notebook import packages. It will work out for sure.

As per the comments in the question... On Windows 10 Signtool.exe and other SDK tools have been moved into "%programfiles(x86)%\Windows Kits\".

Typical path to signtool on Windows 10.

• 32 bit = "c:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe"
• 64 bit = "c:\Program Files (x86)\Windows Kits\10\bin\x64\signtool.exe"

Tools for SDK 8.0 and 8.1 also reside in the "Windows Kits" folder.

You need to install it first. Create a new Dockerfile, and install wget in it:

FROM ubuntu:14.04
RUN  apt-get update \
  && apt-get install -y wget \
  && rm -rf /var/lib/apt/lists/*

Then, build that image:

docker build -t my-ubuntu .

Finally, run it:

docker run my-ubuntu wget https://downloads-packages.s3.amazonaws.com/ubuntu-14.04/gitlab_7.8.2-omnibus.1-1_amd64.deb

You can use this code(Recommended)

 MemoryStream objMS = new MemoryStream();
 DataTable oDT = new DataTable();//Your DataTable which you want to convert
 oDT.WriteXml(objMS);
 objMS.Position = 0;
 XPathDocument result = new XPathDocument(objMS);

This is another way but first ex. is recommended

StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

Run the commented out section once, populate the _TruncateList table with the tables you want truncated, then run the rest of the script. The _ScriptLog table will need to be cleaned up over time if you do this a lot.

You can modify this if you want to do all tables, just put in SELECT name INTO #TruncateList FROM sys.tables. However, you usually don't want to do them all.

Also, this will affect all foreign keys in the database, and you can modify that as well if it's too blunt-force for your application. It's not for my purposes.

Logically there are no difference at all. Performance-wise there are -typically, on most DBMSes- no difference at all.

Handy one-liners

for D in *; do echo "$D"; done
for D in *; do find "$D" -type d; done ### Option A

find * -type d ### Option B

Option A is correct for folders with spaces in between. Also, generally faster since it doesn't print each word in a folder name as a separate entity.

# Option A
$ time for D in ./big_dir/*; do find "$D" -type d > /dev/null; done

As we recently posted on the React blog, in the vast majority of cases you don't need getDerivedStateFromProps at all.

If you just want to compute some derived data, either:

1. Do it right inside render
2. Or, if re-calculating it is expensive, use a memoization helper like memoize-one.

Here's the simplest "after" example:

import memoize from "memoize-one";

class ExampleComponent extends React.Component {
  getDerivedData = memoize(computeDerivedState);

  render() {
    const derivedData = this.getDerivedData(this.props.someValue);
    // ...
  }
}

Check out this section of the blog post to learn more.

include() needs a full file path, relative to the file system's root directory.

This should work:

 include_once("C:/xampp/htdocs/PoliticalForum/headerSite.php");

Environment.GetSystemVariable("%SystemDrive%"); will provide the drive OS installed, and you can set filters to savedialog Obtain file path of C# save dialog box

If you fill the DropdownList through client side script then clear the list before submit the form back to server; then ASP.NET will not complain and the security will be still on.

And to get the data selected from the DDL, you can attach an "OnChange" event to the DDL to collect the value in a hidden Input or in a textbox with Style="display: none;"

This should do the trick.....

reset($array);
while (list($elementKey, $element) = each($array)) {
    while (list($key, $value2) = each($element)) {
        if($key == 'id' && $value == 'searched_value') {
            unset($array[$elementKey]);
        }
    }
}

You can code like this:

$query_select = "SELECT * FROM shouts ORDER BY id DESC LIMIT 8;";
$result_select = mysql_query($query_select) or die(mysql_error());
$rows = array();
while($row = mysql_fetch_array($result_select))
    $rows[] = $row;
foreach($rows as $row){ 
    $ename = stripslashes($row['name']);
    $eemail = stripcslashes($row['email']);
    $epost = stripslashes($row['post']);
    $eid = $row['id'];

    $grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=".md5(strtolower($eemail))."&size=70";

    echo ('<img src = "' . $grav_url . '" alt="Gravatar">'.'<br/>');

    echo $eid . '<br/>';

    echo $ename . '<br/>';

    echo $eemail . '<br/>';

    echo $epost . '<br/><br/><br/><br/>';
}

As you can see, it's still need a loop while to get data from mysql_fetch_array

Useful commands to work in daily life:

git checkout -b "branchname" ->  creates new branch
git branch                   ->  lists all branches
git checkout "branchname"    ->  switches to your branch
git push origin "branchname" ->  Pushes to your branch
git add */filename           -> Stages *(All files) or by given file name
git commit -m "commit message" -> Commits staged files
git push                     -> Pushes to your current branch

If you want to merge to dev from feature branch, First check out dev branch with command "git branch dev/develop" Then enter merge commadn "git merge featurebranchname"

You can do:

t1<- t1[-4:-6,-7:-9]

Java9 uses byte[] to store String.value, so you can only get about 1GB Strings in Java9. Java8 on the other hand can have 2GB Strings.

By character I mean "char"s, some character is not representable in BMP(like some of the emojis), so it will take more(currently 2) chars.

Use https://prestodb.io/docs/current/connector/kafka-tutorial.html

A super SQL engine, provided by Facebook, that connects on several data sources (Cassandra, Kafka, JMX, Redis ...).

PrestoDB is running as a server with optional workers (there is a standalone mode without extra workers), then you use a small executable JAR (called presto CLI) to make queries.

Once you have configured well the Presto server , you can use traditionnal SQL:

This is the hardware serial number. To access it on

• Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices.

• Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN.

• Android 7.1 and earlier (<= SDK 25) and earlier android.os.Build.SERIAL does return a valid serial.

It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here.

For a solution involving reflection without requiring a permission see this answer.

"If you want to Select multiple Cells and Copy their values to the Clipboard without all those annoying quotes" (without the bugs in Peter Smallwood's multi-Cells solution) "the following code may be useful." This is an enhancement of the code given above from Peter Smallwood (which "is an enhancement of the code given above from user3616725"). This fixes the following bugs in Peter Smallwood's solution:

• Avoids "Variable not defined" Compiler Error (for "CR" - "clibboardFieldDelimiter " here)
• Convert an Empty Cell to an empty String vs. "0".
• Append Tab (ASCII 9) vs. CR (ASCII 13) after each Cell.
• Append a CR (ASCII 13) + LF (ASCII 10) (vs. CR (ASCII 13)) after each Row.

NOTE: You still won't be able to copy characters embedded within a Cell that would cause an exit of the target field you're Pasting that Cell into (i.e. Tab or CR when Pasting into the Edit Table Window of Access or SSMS).

Here's a very simple solution that works on my Samsung Galaxy S II and Note 1; I have no idea about other models:

1. Open the phone app and switch to keypad.
2. Dial *#9900#
3. On the screen that appears, click on the button labelled "Delete dumpstate/logcat".

I've restored about one GB of system space this way.

Are you sure you are not mixing tabs and spaces in your indentation white space? (That will cause that error.)

Note, it is recommended that you don't use tabs in Python code. See the style guide. You should configure Notepad++ to insert spaces for tabs.

I just had the same issue on visual studio 2012. For a internet application project. How to resolve “Server Error in '/' Application” error?

Searching for answer I came across this post, but none of these answer help me. Than I found another post here on stackoverflow that has the answer for resolving this issue. Specified argument was out of the range of valid values. Parameter name: site

You could also just use the NSUUID API:

let uuid = NSUUID()

If you want to get the string value back out, you can use uuid.UUIDString.

Note that NSUUID is available from iOS 6 and up.

In Go with "sql.DB" (note the search_path with underscore):

postgres://user:password@host/dbname?sslmode=disable&search_path=schema

See this link. It shows you how to dynamically create variables in PowerShell.

Here is the basic idea:

Use New-Variable and Get-Variable,

for ($i=1; $i -le 5; $i++)
{
    New-Variable -Name "var$i" -Value $i
    Get-Variable -Name "var$i" -ValueOnly
}

(It is taken from the link provided, and I don't take credit for the code.)

If you want do many calculation with 2d array, you should use NumPy array instead of nest list.

for your question, you can use:zip(*a) to transpose it:

In [55]: a=[[1,1],[2,1],[3,1]]
In [56]: zip(*a)
Out[56]: [(1, 2, 3), (1, 1, 1)]
In [57]: zip(*a)[0]
Out[57]: (1, 2, 3)

For my layout, I didn't want a hack (no width increasing, no on click with auto and then coming to original). It broke my existing layout. I just wanted it to work normally like other browsers.

I found this to be exactly like that :-

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

$(document).ready(function () {

        $("img").on('contextmenu', function (e) {
           e.preventDefault();
        });

});

I found the same issue when upgrading to pgAdmin 4 (v1.6). On Windows I found that clearing out the C:\Users\%USERNAME%\AppData\Roaming\pgAdmin folder fixed the issue for me. I believe it was attempting to use the sessions from the prior version and was failing. I know the question was marked as answered, but downgrading may not always be an option.

Note: AppData\Roaming\pgAdmin is a hidden folder.

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

batchfiles perform simple string substitution with variables. so, a simple

goto :language%language%
echo notfound
...

does this without any need for if.

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

Remove all non dot / digits:

var currency = "-$4,400.50";
var number = Number(currency.replace(/[^0-9.-]+/g,""));

tabletext fit this well

import tabletext

data = [[1,2,30],
        [4,23125,6],
        [7,8,999],
        ]

print tabletext.to_text(data)

result:

+-----------------+
¦ 1 ¦     2 ¦  30 ¦
+---+-------+-----¦
¦ 4 ¦ 23125 ¦   6 ¦
+---+-------+-----¦
¦ 7 ¦     8 ¦ 999 ¦
+-----------------+

An easy way to print the sorted contents of the dictionary, in Python 3:

>>> dict_example = {'c': 1, 'b': 2, 'a': 3}
>>> for key, value in sorted(dict_example.items()):
...   print("{} : {}".format(key, value))
... 
a : 3
b : 2
c : 1

The expression dict_example.items() returns tuples, which can then be sorted by sorted():

>>> dict_example.items()
dict_items([('c', 1), ('b', 2), ('a', 3)])
>>> sorted(dict_example.items())
[('a', 3), ('b', 2), ('c', 1)]

Below is an example to pretty print the sorted contents of a Python dictionary's values.

for key, value in sorted(dict_example.items(), key=lambda d_values: d_values[1]): 
    print("{} : {}".format(key, value))

LTRIM(RTRIM(FCT_TYP_CD)) & ') AND (' & LTRIM(RTRIM(DEP_TYP_ID)) & ')'

I think you're missing a ) on both of the trims. Some SQL versions support just TRIM which does both L and R trims...

if you're happy using it as a background image and CSS3 then background-size: cover; would do the trick

As I did not find a proper way I wrote a script to do it and I'm sharing it here for those who need it. The script runs through all user tables and collects the columns. If the column type is any char type then it tries to convert it to the given collation.

Columns has to be index and constraint free for this to work.

If someone still has a better solution to this please post it!

DECLARE @table nvarchar(255);
DECLARE @column_name nvarchar(255);

DECLARE @data_type nvarchar(255);
DECLARE @max_length int;
DECLARE @row_id int;
DECLARE @sql nvarchar(max);
DECLARE @sql_column nvarchar(max);

SET @collate = 'Latin1_General_CI_AS';

DECLARE local_table_cursor CURSOR FOR

Just wrap floated elements in a <div> and give it this CSS:

.wrapper {

display: table;
margin: auto;

}

I think you are talking about class level variables. As mentioned above using global variable/class level variables are not a good practice.

If you really want to use it. and if you are sure that there will not be impact...

Declare any variable out side the method. at the class level with out the variable type

eg:

{
   method()
   {
      a=10
      print(a)
   }

// def a or int a wont work

a=0

}

Where is the file that you're running? If it is in your public html folder, you can do echo dirname(__FILE__);

window.location.assign did not work for me. it downloads fine but downloads without an extension for a CSV file on Windows platform. The following worked for me.

    var blob = new Blob([csvString], { type: 'text/csv' });
    //window.location.assign(window.URL.createObjectURL(blob));
    var link = window.document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    // Construct filename dynamically and set to link.download
    link.download = link.href.split('/').pop() + '.' + extension; 
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);

this works for me:

public static class eSound_Def
{
  private static Android.Media.MediaPlayer mpBeep;

  public static void InitSounds( Android.Content.Res.AssetManager Assets )
  {
    mpBeep = new Android.Media.MediaPlayer();

    InitSound_Beep( Assets );
  }

  private static void InitSound_Beep( Android.Content.Res.AssetManager Assets )
  {
    Android.Content.Res.AssetFileDescriptor AFD;

    AFD = Assets.OpenFd( "Sounds/beep-06.mp3" );
    mpBeep.SetDataSource( AFD.FileDescriptor, AFD.StartOffset, AFD.Length );
    AFD.Close();

    mpBeep.Prepare();
    mpBeep.SetVolume( 1f, 1f );
    mpBeep.Looping = false;
  }

  public static void PlaySound_Beep()
  {
    if (mpBeep.IsPlaying == true) 
    {
      mpBeep.Stop();
      mpBeep.Reset();
      InitSound_Beep(); 
    }
    mpBeep.Start();
  }
}

In main activity, on create:

protected override void OnCreate( Bundle savedInstanceState )
{
  base.OnCreate( savedInstanceState );
  SetContentView( Resource.Layout.lmain_activity );
  ...
  eSound_Def.InitSounds( Assets );
  ...
}

how to use in code (on button click):

private void bButton_Click( object sender, EventArgs e )
{
  eSound_Def.PlaySound_Beep();
}

Unless your compiler is different than the one supplied with the Mac XCode Dev tools, just follow the instructions in section 5.1 of Getting Started Guide for Unix Variants. The configuration and building of the latest source couldn't be easier, and it took all about about 1 minute to configure and 10 minutes to compile.
