I faced exactly the same issue. My home drive mapped to a network drive. Also

1. No Write access to home drive
2. No write access to Git bash profile
3. No admin rights to change environment variables from control panel.

However below worked from command line and I was able to add HOME to environment variables.

As noted in Chris Dolan's and Wilbert's answers, PS1 slows you down.

Rather than completely disabling (as suggested by Dolan) or using the script offered by Wilbert, I use a "dumb PS1" that is much faster.

It uses (git symbolic-ref -q HEAD || git rev-parse --short HEAD) 2> /dev/null:

PS1='\033[33m\]\w \n\[\033[32m\]$((git symbolic-ref -q HEAD || git rev-parse -q --short HEAD) 2> /dev/null) \[\033[00m\]# '

On my Cygwin, this is faster than Wilbert's "fast_Git_PS1" answer - 200 ms vs. 400 ms, so it shaves off a bit of your prompt sluggishness.

It isn't as sophisticated as __git_ps1 - for example it doesn't change the prompt when you cd into the .git directory, etc. but for normal everyday use it's good enough and fast.

This was tested on Git 1.7.9 (Cygwin, but it should work on any platform).

I got this error when using the Atom editor and mingw (through a package called gpp-compiler) for C++. Closing the open console window fixed my issue.

I use GateOne from the synocommunity.

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

If you want to use environment variable during build. Lets say setting username and password.

username= Ubuntu
password= swed24sw

Dockerfile

FROM ubuntu:16.04
ARG SMB_PASS
ARG SMB_USER
# Creates a new User
RUN useradd -ms /bin/bash $SMB_USER
# Enters the password twice.
RUN echo "$SMB_PASS\n$SMB_PASS" | smbpasswd -a $SMB_USER

Terminal Command

docker build --build-arg SMB_PASS=swed24sw --build-arg SMB_USER=Ubuntu . -t IMAGE_TAG

I use this function in my python programs. The input for the function is as example:
value = time.time()

def stopWatch(value):
    '''From seconds to Days;Hours:Minutes;Seconds'''

    valueD = (((value/365)/24)/60)
    Days = int (valueD)

    valueH = (valueD-Days)*365
    Hours = int(valueH)

    valueM = (valueH - Hours)*24
    Minutes = int(valueM)

    valueS = (valueM - Minutes)*60
    Seconds = int(valueS)


    print Days,";",Hours,":",Minutes,";",Seconds




start = time.time() # What in other posts is described is

***your code HERE***

end = time.time()         
stopWatch(end-start) #Use then my code

This is because charset=utf8 should be without a space after application/json. That will work fine. Use it like application/json;charset=utf-8

White background is caused because of the Android starts while the app loads on memory, and it can be avoided if you just add this 2 line of code under SplashTheme.

<item name="android:windowDisablePreview">true</item>
<item name="android:windowIsTranslucent">true</item>

Take a try on the tiny free tool:

http://keyangxiang.com/csvtojson/

It utilises node.js csvtojson module

try it-

var radioVal = $("#myform").find("input[type='radio']:checked").val();

console.log(radioVal);

After much digging around we were able to scrape the info more or less (mainly from Keycloak's own JS client lib):

• Authorization Endpoint: /auth/realms/{realm}/tokens/login
• Token Endpoint: /auth/realms/{realm}/tokens/access/codes

As for OpenID Connect UserInfo, right now (1.1.0.Final) Keycloak doesn't implement this endpoint, so it is not fully OpenID Connect compliant. However, there is already a patch that adds that as of this writing should be included in 1.2.x.

But - Ironically Keycloak does send back an id_token in together with the access token. Both the id_token and the access_token are signed JWTs, and the keys of the token are OpenID Connect's keys, i.e:

"iss":  "{realm}"
"sub":  "5bf30443-0cf7-4d31-b204-efd11a432659"
"name": "Amir Abiri"
"email: "..."

So while Keycloak 1.1.x is not fully OpenID Connect compliant, it does "speak" in OpenID Connect language.

According to the documentation, just like with any css selector, you can specify as many conditions as you want, and they are treated as logical 'OR'.

This example returns a list of all div elements within the document with a class of either "note" or "alert":

var matches = document.querySelectorAll("div.note, div.alert");

source: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll

Meanwhile to get the 'AND' functionality you can for example simply use a multiattribute selector, as jquery says:

https://api.jquery.com/multiple-attribute-selector/

ex. "input[id][name$='man']" specifies both id and name of the element and both conditions must be met. For classes it's as obvious as ".class1.class2" to require object of 2 classes.

All possible combinations of both are valid, so you can easily get equivalent of more sophisticated 'OR' and 'AND' expressions.

If you want to install a bunch of dependencies from, say a requirements.txt, you would do:

mkdir dependencies
pip download -r requirements.txt -d "./dependencies"
tar cvfz dependencies.tar.gz dependencies

And, once you transfer the dependencies.tar.gz to the machine which does not have internet you would do:

tar zxvf dependencies.tar.gz
cd dependencies
pip install * -f ./ --no-index

Simply use \1 instead of $1:

In [1]: import re

In [2]: method = 'images/:id/huge'

In [3]: re.sub(r'(:[a-z]+)', r'<span>\1</span>', method)
Out[3]: 'images/<span>:id</span>/huge'

Also note the use of raw strings (r'...') for regular expressions. It is not mandatory but removes the need to escape backslashes, arguably making the code slightly more readable.

Code :

var now = new Date();
var time = now.getTime();
time += 3600 * 1000;
now.setTime(time);
document.cookie = 
'username=' + value + 
'; expires=' + now.toUTCString() + 
'; path=/';

add java security in your run command

java -jar -Djava.security.egd="file:///dev/urandom" yourjarfilename.jar

I had the same exception on Tomcat.. I found another problem - when i use wsimport over maven plugin to generate stubs for more then 1 WSDLs - class ObjectFactory (stubs references to this class) contains methods ONLY for one wsdl. So you should merge all methods in one ObjectFactory class (for each WSDL) or generate each wsdl stubs in different directories (there will be separates ObjectFactory classes). It solves problem for me with this exception..J

I was able to resolve this by following the steps posted here: xampp phpmyadmin, Incorrect format parameter

Because I'm not using XAMPP, I also needed to update my php.ini.default to php.ini which finally did the trick.

The issue here is that you've opened a file and read its contents so the cursor is at the end of the file. By writing to the same file handle, you're essentially appending to the file.

The easiest solution would be to close the file after you've read it in, then reopen it for writing.

with open("replayScript.json", "r") as jsonFile:
    data = json.load(jsonFile)

data["location"] = "NewPath"

with open("replayScript.json", "w") as jsonFile:
    json.dump(data, jsonFile)

Alternatively, you can use seek() to move the cursor back to the beginning of the file then start writing, followed by a truncate() to deal with the case where the new data is smaller than the previous.

with open("replayScript.json", "r+") as jsonFile:
    data = json.load(jsonFile)

    data["location"] = "NewPath"

    jsonFile.seek(0)  # rewind
    json.dump(data, jsonFile)
    jsonFile.truncate()

Here's a quick dynamic modern solution which I thought I'll share

const generatePassword = (
  passwordLength = 8,
  useUpperCase = true,
  useNumbers = true,
  useSpecialChars = true,
) => {
  const chars = 'abcdefghijklmnopqrstuvwxyz'
  const numberChars = '0123456789'
  const specialChars = '!"£$%^&*()'

  const usableChars = chars
   + (useUpperCase ? chars.toUpperCase() : '')
   + (useNumbers ? numberChars : '')
   + (useSpecialChars ? specialChars : '')

  let generatedPassword = ''

  for(i = 0; i <= passwordLength; i++) {
    generatedPassword += usableChars[Math.floor(Math.random() * (usableChars.length))]
  }

  return generatedPassword
}

I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.

I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.

Just make sure to execute commit or rollback after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.

As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost'; does not work is quite simple : There is no grant called USAGE.

The actual named grants are in the MySQL Documentation

The grant USAGE is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE. Running DROP USER 'phpmyadmin'@'localhost'; should work just fine. Under the hood, it's really doing this:

DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db   WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;

Therefore, the removal of a row from mysql.user constitutes running REVOKE USAGE, even though REVOKE USAGE cannot literally be executed.

Simple, but complete example showing how to display QImage might look like this:

#include <QtGui/QApplication>
#include <QLabel>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QImage myImage;
    myImage.load("test.png");

    QLabel myLabel;
    myLabel.setPixmap(QPixmap::fromImage(myImage));

    myLabel.show();

    return a.exec();
}

I used a different kind of stack. Here is the implementation.

Minimum element is: 1

Try it. I think it answers the question. The second element of every pair gives the minimum value seen when that element was inserted.

There's no need to use custom serializers/deserializers here. Use jackson-modules-java8's datetime module:

Datatype module to make Jackson recognize Java 8 Date & Time API data types (JSR-310).

This module adds support for quite a few classes:

• Duration
• Instant
• LocalDateTime
• LocalDate
• LocalTime
• MonthDay
• OffsetDateTime
• OffsetTime
• Period
• Year
• YearMonth
• ZonedDateTime
• ZoneId
• ZoneOffset

        This is the simple answer how to add datas dynamically in listview android kotlin


class MainActivity : AppCompatActivity(){
        
            var listItems = arrayListOf<String>()
            val array = arrayOf("a","b","c","d","e")
            var listView: ListView? = null
    
            private lateinit var adapter: listViewAdapter
        
            override fun onCreate(savedInstanceState: Bundle?) {
                super.onCreate(savedInstanceState)
                setContentView(R.layout.scrollview_layout)
        
                listItems.add("a")
                listItems.add("b")
                listItems.add("c")
                listItems.add("d")
                listItems.add("e")

      double value = 3.4555;
      String value1 =  String.format("% .3f", value) ;
      String value2 = value1.substring(0, value1.length() - 1);
      System.out.println(value2);         
      double doublevalue= Double.valueOf(value2);
      System.out.println(doublevalue);

Extension for UISegmentedControl for setting Font Size.

extension UISegmentedControl {
    @available(iOS 8.2, *)
    func setFontSize(fontSize: CGFloat) {
            let normalTextAttributes: [NSObject : AnyObject]!
            if #available(iOS 9.0, *) {
                normalTextAttributes = [
                    NSFontAttributeName: UIFont.monospacedDigitSystemFontOfSize(fontSize, weight: UIFontWeightRegular)
                ]
            } else {
                normalTextAttributes = [
                    NSFontAttributeName: UIFont.systemFontOfSize(fontSize, weight: UIFontWeightRegular)
                ]
            }

        self.setTitleTextAttributes(normalTextAttributes, forState: .Normal)
    }
 }

we can use createNativeQuery("Here Nagitive SQL Query ");

for Example :

Query q = em.createNativeQuery("SELECT a.firstname, a.lastname FROM Author a");
List<Object[]> authors = q.getResultList();

I just came up with a tricky way to get almost the same functionality. Instead of protecting the sheet the normal way, use an event handler to undo anything the user tries to do.

Add the following to the worksheet's module:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Locked = True Then
        Application.EnableEvents = False
        Application.Undo
        Application.EnableEvents = True
    End If
End Sub

If the user does anything to change a cell that's locked, the action will get immediately undone. The temporary disabling of events is to keep the undoing itself from triggering this event, resulting in an infinite loop.

Sorting and filtering do not trigger the Change event, so those functions remain enabled.

Note that this solution prevents changing or clearing cell contents, but does not prevent changing formats. A determined user could get around it by simply setting the cells to be unlocked.

If, for whatever reason (e.g. Space Engineers API), System.array has no definition for Max nor do you have access to Enumerable, a solution for Max of n values is:

public int Max(int[] values) {
    if(values.Length < 1) {
        return 0;
    }
    if(values.Length < 2) {
        return values[0];
    }
    if(values.Length < 3) {
       return Math.Max(values[0], values[1]); 
    }
    int runningMax = values[0];
    for(int i=1; i<values.Length - 1; i++) {
       runningMax = Math.Max(runningMax, values[i]);
    }
    return runningMax;
}

Yes, there is awesome simple bash script I found, which allows you to update the Postman Linux app, straight from the terminal, called postman-updater-linux.

Just install it using NPM:

npm install -g postman-updater-linux

Then check for updates:

sudo postman-updater check

Then install:

sudo postman-updater install

Or update:

sudo postman-updater update

All three last commands can be used with custom location by adding -l /your/custom/path to end of this command.

 public class Stack {
     int[] arr;
     int MAX_SIZE;
     int top;

public Stack(int n){
    MAX_SIZE = n;
    arr = new int[MAX_SIZE];
    top=0;
}

    public boolean isEmpty(){
        if(top ==0)
            return true;
      else
        return false;
   }

public boolean push(int ele){

    if(top<MAX_SIZE){
        arr[top] = ele;
        top++;
        return true;
    }
    else{
        System.out.println("Stack is full");
        return false;
    }
}
public void show(){
    for(int element:arr){
        System.out.print(element+" ");
    }
}
public int size(){
    return top;
}
   public int peek(){
        if(!isEmpty()){
            int peekTest = arr[top-1];
            return peekTest;
                    }
   else{
       System.out.println("Stack is empty");
       return 0;
   } 
}
public int pop(){
    if(isEmpty()){
        System.out.println("Stack is Emmpty");
        return 0;
    }
    else{
        int element = arr[--top];
        return element;
    }
}

}

The Django documentation for database queries includes a section on copying model instances. Assuming your primary keys are autogenerated, you get the object you want to copy, set the primary key to None, and save the object again:

blog = Blog(name='My blog', tagline='Blogging is easy')
blog.save() # blog.pk == 1

blog.pk = None
blog.save() # blog.pk == 2

In this snippet, the first save() creates the original object, and the second save() creates the copy.

If you keep reading the documentation, there are also examples on how to handle two more complex cases: (1) copying an object which is an instance of a model subclass, and (2) also copying related objects, including objects in many-to-many relations.

Note on miah's answer: Setting the pk to None is mentioned in miah's answer, although it's not presented front and center. So my answer mainly serves to emphasize that method as the Django-recommended way to do it.

Historical note: This wasn't explained in the Django docs until version 1.4. It has been possible since before 1.4, though.

Possible future functionality: The aforementioned docs change was made in this ticket. On the ticket's comment thread, there was also some discussion on adding a built-in copy function for model classes, but as far as I know they decided not to tackle that problem yet. So this "manual" way of copying will probably have to do for now.

I based this additional function on Nick Stinemates

def add_node_at_end(self, data):
    new_node = Node()
    node = self.curr_node
    while node:
        if node.next == None:
            node.next = new_node
            new_node.next = None
            new_node.data = data
        node = node.next

The method he has adds the new node at the beginning while I have seen a lot of implementations which usually add a new node at the end but whatever, it is fun to do.

Just try to add this line to your manifest file:

<uses-permission android:name="android.permission.READ_PHONE_STATE" tools:node="remove" />

and add attribute xmlns:tools="http://schemas.android.com/tools" to your <manifest> tag to define namespace tools

From the documentation for tools:node="remove":

Remove this element from the merged manifest. Although it seems like you should instead just delete this element, using this is necessary when you discover an element in your merged manifest that you don't need, and it was provided by a lower-priority manifest file that's out of your control (such as an imported library).

As others have noted, you can't have immutable arrays in Java.

If you absolutely need a method that returns an array that doesn't influence the original array, then you'd need to clone the array each time:

public int[] getFooArray() {
  return fooArray == null ? null : fooArray.clone();
}

Obviously this is rather expensive (as you'll create a full copy each time you call the getter), but if you can't change the interface (to use a List for example) and can't risk the client changing your internals, then it may be necessary.

This technique is called making a defensive copy.

 for(int i=0;i<ytFiles.size();i++){

                    int key = ytFiles.keyAt(i);
                    Log.e("key", String.valueOf(key));
                    String format = ytFiles.get(key).getFormat().toString();
                    String url = ytFiles.get(key).getUrl();
                    Log.e("url",url);
                }

you can get key by method keyat and you have to pass the index then it will return key at that particular index. this loop will get all the key

what you are trying to do is more a segmentedbutton than an imagebutton list.

here http://blog.bookworm.at/2010/10/segmented-controls-in-android.html is an example on how to do so. The basic idea is to customize RadioButton instead of ImageButton, since the RadioButton will have the checked state you need

Have you tried url-encoding the data ? cURL can take care of that for you :

mode: 'no-cors' won’t magically make things work. In fact it makes things worse, because one effect it has is to tell browsers, “Block my frontend JavaScript code from looking at contents of the response body and headers under all circumstances.” Of course you almost never want that.

What happens with cross-origin requests from frontend JavaScript is that browsers by default block frontend code from accessing resources cross-origin. If Access-Control-Allow-Origin is in a response, then browsers will relax that blocking and allow your code to access the response.

But if a site sends no Access-Control-Allow-Origin in its responses, your frontend code can’t directly access responses from that site. In particular, you can’t fix it by specifying mode: 'no-cors' (in fact that’ll ensure your frontend code can’t access the response contents).

However, one thing that will work: if you send your request through a CORS proxy.

You can also easily deploy your own proxy to Heroku in literally just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master

After running those commands, you’ll end up with your own CORS Anywhere server running at, for example, https://cryptic-headland-94862.herokuapp.com/.

Prefix your request URL with your proxy URL; for example:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

I can hit this endpoint, http://catfacts-api.appspot.com/api/facts?number=99 via Postman

https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS explains why it is that even though you can access the response with Postman, browsers won’t let you access the response cross-origin from frontend JavaScript code running in a web app unless the response includes an Access-Control-Allow-Origin response header.

http://catfacts-api.appspot.com/api/facts?number=99 has no Access-Control-Allow-Origin response header, so there’s no way your frontend code can access the response cross-origin.

Your browser can get the response fine and you can see it in Postman and even in browser devtools—but that doesn’t mean browsers will expose it to your code. They won’t, because it has no Access-Control-Allow-Origin response header. So you must instead use a proxy to get it.

The proxy makes the request to that site, gets the response, adds the Access-Control-Allow-Origin response header and any other CORS headers needed, then passes that back to your requesting code. And that response with the Access-Control-Allow-Origin header added is what the browser sees, so the browser lets your frontend code actually access the response.

So I am trying to pass in an object, to my Fetch which will disable CORS

You don’t want to do that. To be clear, when you say you want to “disable CORS” it seems you actually mean you want to disable the same-origin policy. CORS itself is actually a way to do that — CORS is a way to loosen the same-origin policy, not a way to restrict it.

But anyway, it’s true you can — in just your local environment — do things like give your browser runtime flags to disable security and run insecurely, or you can install a browser extension locally to get around the same-origin policy, but all that does is change the situation just for you locally.

No matter what you change locally, anybody else trying to use your app is still going to run into the same-origin policy, and there’s no way you can disable that for other users of your app.

You most likely never want to use mode: 'no-cors' in practice except in a few limited cases, and even then only if you know exactly what you’re doing and what the effects are. That’s because what setting mode: 'no-cors' actually says to the browser is, “Block my frontend JavaScript code from looking into the contents of the response body and headers under all circumstances.” In most cases that’s obviously really not what you want.

As far as the cases when you would want to consider using mode: 'no-cors', see the answer at What limitations apply to opaque responses? for the details. The gist of it is that the cases are:

• In the limited case when you’re using JavaScript to put content from another origin into a <script>, <link rel=stylesheet>, <img>, <video>, <audio>, <object>, <embed>, or <iframe> element (which works because embedding of resources cross-origin is allowed for those) — but for some reason you don’t want to or can’t do that just by having the markup of the document use the resource URL as the href or src attribute for the element.

• When the only thing you want to do with a resource is to cache it. As alluded to in the answer What limitations apply to opaque responses?, in practice the scenario that applies to is when you’re using Service Workers, in which case the API that’s relevant is the Cache Storage API.

But even in those limited cases, there are some important gotchas to be aware of; see the answer at What limitations apply to opaque responses? for the details.

I have also tried to pass in the object { mode: 'opaque'}

There is no mode: 'opaque' request mode — opaque is instead just a property of the response, and browsers set that opaque property on responses from requests sent with the no-cors mode.

But incidentally the word opaque is a pretty explicit signal about the nature of the response you end up with: “opaque” means you can’t see it.

This post is regarding fetching only Distincts rows from Data table on basis of multiple Columns.

Public coid removeDuplicatesRows(DataTable dt)
{
  DataTable uniqueCols = dt.DefaultView.ToTable(true, "RNORFQNo", "ManufacturerPartNo",  "RNORFQId", "ItemId", "RNONo", "Quantity", "NSNNo", "UOMName", "MOQ", "ItemDescription");
} 

You need to call this method and you need to assign value to datatable. In Above code we have RNORFQNo , PartNo,RFQ id,ItemId, RNONo, QUantity, NSNNO, UOMName,MOQ, and Item Description as Column on which we want distinct values.

Some extra information about .NET Core (after reading erdomke's post about setting a private field to supply the content-type on a request that doesn't have content)...

After debugging my code, I can't see the private field to set via reflection - so I thought I'd try to recreate the problem.

I have tried the following code using .Net 4.6:

HttpRequestMessage httpRequest = new HttpRequestMessage(HttpMethod.Get, @"myUrl");
httpRequest.Content = new StringContent(string.Empty, Encoding.UTF8, "application/json");

HttpClient client = new HttpClient();
Task<HttpResponseMessage> response =  client.SendAsync(httpRequest);  //I know I should have used async/await here!
var result = response.Result;

And, as expected, I get an aggregate exception with the content "Cannot send a content-body with this verb-type."

However, if i do the same thing with .NET Core (1.1) - I don't get an exception. My request was quite happily answered by my server application, and the content-type was picked up.

I was pleasantly surprised about that, and I hope it helps someone!

With bootstrap 3, just add the responsive and center classes:

 <img class="img-responsive center-block" src="img/....jpg" alt="First slide">

This automatically does image resizing, and centers the picture.

Edit:

With bootstrap 4, just add the img-fluid class

<img class="img-fluid" src="img/....jpg">

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

This question is old, but I wanted to add my two-cents. I read the question as " I want to run a query to my [my]SQL database and store the returned data as Pandas data structure [DataFrame]."

From the code it looks like you mean mysql database and assume you mean pandas DataFrame.

import MySQLdb as mdb
import pandas.io.sql as sql
from pandas import *

conn = mdb.connect('<server>','<user>','<pass>','<db>');
df = sql.read_frame('<query>', conn)

For example,

conn = mdb.connect('localhost','myname','mypass','testdb');
df = sql.read_frame('select * from testTable', conn)

This will import all rows of testTable into a DataFrame.

The key is git submodules.

Start reading the Submodules chapter of the Git Community Book or of the Users Manual

Say you have repository PROJECT1, PROJECT2, and MEDIA...

cd /path/to/PROJECT1
git submodule add ssh://path.to.repo/MEDIA
git commit -m "Added Media submodule"

Repeat on the other repo...

Now, the cool thing is, that any time you commit changes to MEDIA, you can do this:

cd /path/to/PROJECT2/MEDIA
git pull
cd ..
git add MEDIA
git commit -m "Upgraded media to version XYZ"

This just recorded the fact that the MEDIA submodule WITHIN PROJECT2 is now at version XYZ.

It gives you 100% control over what version of MEDIA each project uses. git submodules are great, but you need to experiment and learn about them.

With great power comes the great chance to get bitten in the rump.

Here is a sample code with explanation.

 //Create a response instance
 $response = new Illuminate\Http\Response('Hello World');

 //Call the withCookie() method with the response method
 $response->withCookie(cookie('name', 'value', $minutes));

 //return the response
 return $response;

Cookie can be set forever by using the forever method as shown in the below code.

$response->withCookie(cookie()->forever('name', 'value'));

Retrieving a Cookie

//’name’ is the name of the cookie to retrieve the value of
$value = $request->cookie('name');

numpy.isnan(number) tells you if it's NaN or not.

Just to add to Jon's coding if you needed to take it a step further, and do more than just one column you can add something like

Dim copyRange2 As Range
Dim copyRange3 As Range

Set copyRange2 =src.Range("B2:B" & lastRow)
Set copyRange3 =src.Range("C2:C" & lastRow)

copyRange2.SpecialCells(xlCellTypeVisible).Copy tgt.Range("B12")
copyRange3.SpecialCells(xlCellTypeVisible).Copy tgt.Range("C12")

put these near the other codings that are the same you can easily change the Ranges as you need.

I only add this because it was helpful for me. I'd assume Jon already knows this but for those that are less experienced sometimes it's helpful to see how to change/add/modify these codings. I figured since Ruya didn't know how to manipulate the original coding it could be helpful if one ever needed to copy over only 2 visibile columns, or only 3, etc. You can use this same coding, add in extra lines that are almost the same and then the coding is copying over whatever you need.

I don't have enough reputation to reply to Jon's comment directly so I have to post as a new comment, sorry.

Compiled expression is best way! (for performance to repeatedly create instance in runtime).

static readonly Func<X> YCreator = Expression.Lambda<Func<X>>(
   Expression.New(typeof(Y).GetConstructor(Type.EmptyTypes))
 ).Compile();

X x = YCreator();

If you'd like to persisist cookies and session data, you'd best do it like this:

import requests

proxies = {
    'http': 'http://user:[email protected]:3128',
    'https': 'https://user:[email protected]:3128',
}

# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies

# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')

In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).

You get the question-mark-diamond characters when your textfile uses high-ANSI encoding -- meaning it uses characters between 127 and 255. Those characters have the eighth (i.e. the most significant) bit set. When ASP.NET reads the textfile it assumes UTF-8 encoding, and that most significant bit has a special meaning.

You must force ASP.NET to interpret the textfile as high-ANSI encoding, by telling it the codepage is 1252:

String textFilePhysicalPath = System.Web.HttpContext.Current.Server.MapPath("~/textfiles/MyInputFile.txt");
String contents = File.ReadAllText(textFilePhysicalPath, System.Text.Encoding.GetEncoding(1252));
lblContents.Text = contents.Replace("\n", "<br />");  // change linebreaks to HTML

Supposing the form is the direct parent you can do:

<a href='#' onclick='this.parentNode.submit(); return false;'>submit</a>

If not you can access through the forms name attribute like this:

<a href='#' onclick='document.forms["myform"].submit(); return false;'>submit</a>

See both examples here: http://jsfiddle.net/WEZDC/1/

Here is how you can find mean,median and mode of a list:

import numpy as np
from scipy import stats

#to take input
size = int(input())
numbers = list(map(int, input().split()))

print(np.mean(numbers))
print(np.median(numbers))
print(int(stats.mode(numbers)[0]))

Be careful with setup projects if you're using them; Visual Studio setup projects Primary Output pulls from the obj folder rather than the bin.

I was releasing applications I thought were obfuscated and signed in msi setups for quite a while before I discovered that the deployed application files were actually neither obfuscated nor signed as I as performing the post-build procedure on the bin folder assemblies and should have been targeting the obj folder assemblies instead.

This is far from intuitive imho, but the general setup approach is to use the Primary Output of the project and this is the obj folder. I'd love it if someone could shed some light on this btw.

The answer I would provide is that a keystore file is to authenticate yourself to anyone who is asking. It isn't restricted to just signing .apk files, you can use it to store personal certificates, sign data to be transmitted and a whole variety of authentication.

In terms of what you do with it for Android and probably what you're looking for since you mention signing apk's, it is your certificate. You are branding your application with your credentials. You can brand multiple applications with the same key, in fact, it is recommended that you use one certificate to brand multiple applications that you write. It easier to keep track of what applications belong to you.

I'm not sure what you mean by implications. I suppose it means that no one but the holder of your certificate can update your application. That means that if you release it into the wild, lose the cert you used to sign the application, then you cannot release updates so keep that cert safe and backed up if need be.

But apart from signing apks to release into the wild, you can use it to authenticate your device to a server over SSL if you so desire, (also Android related) among other functions.

Atomicity atomic (default)

Atomic is the default: if you don’t type anything, your property is atomic. An atomic property is guaranteed that if you try to read from it, you will get back a valid value. It does not make any guarantees about what that value might be, but you will get back good data, not just junk memory. What this allows you to do is if you have multiple threads or multiple processes pointing at a single variable, one thread can read and another thread can write. If they hit at the same time, the reader thread is guaranteed to get one of the two values: either before the change or after the change. What atomic does not give you is any sort of guarantee about which of those values you might get. Atomic is really commonly confused with being thread-safe, and that is not correct. You need to guarantee your thread safety other ways. However, atomic will guarantee that if you try to read, you get back some kind of value.

nonatomic

On the flip side, non-atomic, as you can probably guess, just means, “don’t do that atomic stuff.” What you lose is that guarantee that you always get back something. If you try to read in the middle of a write, you could get back garbage data. But, on the other hand, you go a little bit faster. Because atomic properties have to do some magic to guarantee that you will get back a value, they are a bit slower. If it is a property that you are accessing a lot, you may want to drop down to nonatomic to make sure that you are not incurring that speed penalty. Access

courtesy https://academy.realm.io/posts/tmi-objective-c-property-attributes/

Atomicity property attributes (atomic and nonatomic) are not reflected in the corresponding Swift property declaration, but the atomicity guarantees of the Objective-C implementation still hold when the imported property is accessed from Swift.

So — if you define an atomic property in Objective-C it will remain atomic when used by Swift.

In c# following code insert data into datatable on specified position

DataTable dt = new DataTable();
dt.Columns.Add("SL");
dt.Columns.Add("Amount");

dt.rows.add(1, 1000)
dt.rows.add(2, 2000)

dt.Rows.InsertAt(dt.NewRow(), 3);

var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;

You can use WMI to get CPU percentage information. You can even log into a remote computer if you have the correct permissions. Look at http://www.csharphelp.com/archives2/archive334.html to get an idea of what you can accomplish.

Also helpful might be the MSDN reference for the Win32_Process namespace.

See also a CodeProject example How To: (Almost) Everything In WMI via C#.

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

Basically, you have three options:

1. Neither specify EXPOSE nor -p
2. Only specify EXPOSE
3. Specify EXPOSE and -p

1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself.

2) If you EXPOSE a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.

3) If you EXPOSE and -p a port, the service in the container is accessible from anywhere, even outside Docker.

The reason why both are separated is IMHO because:

• choosing a host port depends on the host and hence does not belong to the Dockerfile (otherwise it would be depending on the host),
• and often it's enough if a service in a container is accessible from other containers.

The documentation explicitly states:

The EXPOSE instruction exposes ports for use within links.

It also points you to how to link containers, which basically is the inter-container communication I talked about.

PS: If you do -p, but do not EXPOSE, Docker does an implicit EXPOSE. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p includes EXPOSE. That's why I didn't list it above as a fourth case.

You can overwrite the classes in your own css using !important, e.g. if you want to get rid of the rounded corners.

.ui-corner-all
{
border-radius: 0px !important;
}

If you want to use a hex code, here is the best way to do so.

First, define this at the top of your class:

#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

Then inside the "application didFinishLaunchingWithOptions", put this:

[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x00b0f0)];

Put you hex code in place of the 00b0f0.

CORS (Cross-Origin Resource Sharing) and SOP (Same-Origin Policy) are server-side configurations that clients decide to enforce or not.

Related to clients

• Most Browsers do enforce it to prevent issues related to CSRF attack.
• Most Development tools don't care about it.

Here is a Swift way to get screen sizes, this also takes current interface orientation into account:

var screenWidth: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.width
    } else {
        return UIScreen.mainScreen().bounds.size.height
    }
}
var screenHeight: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.height
    } else {
        return UIScreen.mainScreen().bounds.size.width
    }
}
var screenOrientation: UIInterfaceOrientation {
    return UIApplication.sharedApplication().statusBarOrientation
}

These are included as a standard function in:

https://github.com/goktugyil/EZSwiftExtensions

I found all answers above incomplete somehow, Below are exact steps to get it working.

1. We use npm in order to install the package. For this open the Console and go to your Laravel application directory. Enter the following:

   npm install font-awesome --save-dev

2. Now we have to copy the needed files to the public/css and public/fonts directory. In order to do this open the webpack.mix.js file and add the following:

   mix.copy('node_modules/font-awesome/css/font-awesome.min.css', 'public/css'); mix.copy('node_modules/font-awesome/fonts/*', 'public/fonts');

3. Run the following command in order to execute Laravel Mix:

   npm run dev

4. Add the stylesheet for the Font Awesome in your applications layout file (resources/views/layouts/app.blade.phpapp.blade.php):

   <link href="{{ asset('css/font-awesome.min.css') }}" rel="stylesheet" />

5. Use font awesome icons in templates like

   <i class="fa fa-address-book" aria-hidden="true"></i>

I hope it helps!

Sometimes you want to have your GridView as simple as:

  <asp:GridView ID="grid" runat="server" />

You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.

protected void Page_Load(object sender, EventArgs e)
{
  grid.RowDataBound += grid_RowDataBound;
  // Your DB access code here...
  // grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  // grid.DataBind();
}

void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType != DataControlRowType.DataRow)
    return;
  var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
  e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}

The results shown here.

var insertedElement = parentElement.insertBefore(newElement, referenceElement);

If referenceElement is null, or undefined, newElement is inserted at the end of the list of child nodes.

insertedElement The node being inserted, that is newElement
parentElement The parent of the newly inserted node.
newElement The node to insert.
referenceElement The node before which newElement is inserted.

Examples can be found here: Node.insertBefore

You can use inline-flex as well which works pretty good and may be a little cleaner than modifying every row element with CSS.

For my project I wanted every row who's child elements had borders to be the same height so the borders would look jagged. For this I created a simple css class.

.row.borders{
    display: inline-flex;
    width: 100%;
}

var secondsToTime = function(duration) {
  var date = new Date(duration);

  return "%hours:%minutes:%seconds:%milliseconds"
    .replace('%hours', date.getHours())
    .replace('%minutes', date.getMinutes())
    .replace('%seconds', date.getSeconds())
    .replace('%milliseconds', date.getMilliseconds());
}

In order to center text in md files you can use the center tag like html tag:

<center>Centered text</center>

Here is my experience after following the hints on this page.

1. pyPDF can't embed images into files. It can only split and merge. (Source: Ctrl+F through its documentation page) Which is great, but not if you have images that are not already embedded in a PDF.

2. pyPDF2 doesn't seem to have any extra documentation on top of pyPDF.

3. ReportLab is very extensive. (Userguide) However, with a bit of Ctrl+F and grepping through its source, I got this:

   • First, download the Windows installer and source

   • Then try this on Python command line:

     from reportlab.pdfgen import canvas
     from reportlab.lib.units import inch, cm
     c = canvas.Canvas('ex.pdf')
     c.drawImage('ar.jpg', 0, 0, 10*cm, 10*cm)
     c.showPage()
     c.save()
     

All I needed is to get a bunch of images into a PDF, so that I can check how they look and print them. The above is sufficient to achieve that goal.

ReportLab is great, but would benefit from including helloworlds like the above prominently in its documentation.

Angular; with IDE keyCode deprecated warning

Functionally the same as rinku's answer but with IDE warning prevention

numericOnly(event): boolean {
    // noinspection JSDeprecatedSymbols
    const charCode = (event.which) ? event.which : event.key || event.keyCode;  // keyCode is deprecated but needed for some browsers
    return !(charCode === 101 || charCode === 69 || charCode === 45 || charCode === 43);
}

I just write a small gem random_token to generate random tokens for most use case, enjoy ~

You sure the timer isn't outliving the 'dbiSchedule' somehow and firing after the 'dbiSchedule' has been been disposed of?

If that is the case you might be able to recreate it more consistently if the timer fires more quickly thus increasing the chances of you closing the Form just as the timer is firing.

You can call the function created in another js file from the file you are working in. So for this firstly you need to add the external js file into the html document as-

<html>
<head>
    <script type="text/javascript" src='path/to/external/js'></script>
</head>
<body>
........

The function defined in the external javascript file -

$.fn.yourFunctionName = function(){
    alert('function called succesfully for - ' + $(this).html() );
}

To call this function in your current file, just call the function as -

......
<script type="text/javascript">
    $(function(){
        $('#element').yourFunctionName();
    });
</script>

If you want to pass the parameters to the function, then define the function as-

$.fn.functionWithParameters = function(parameter1, parameter2){
        alert('Parameters passed are - ' + parameter1 + ' , ' + parameter2);
}

And call this function in your current file as -

$('#element').functionWithParameters('some parameter', 'another parameter');

In your code you are querying for the payment element in default namespace, but in the XML response it is declared as in http://apilistener.envoyservices.com namespace.

So, you are missing a namespace declaration:

$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');

Now you can use the envoy namespace prefix in your xpath query:

xpath('//envoy:payment')

The full code would be:

$xml = simplexml_load_string($soap_response);
$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');
foreach ($xml->xpath('//envoy:payment') as $item)
{
    print_r($item);
}

Note: I removed the soap namespace declaration as you do not seem to be using it (it is only useful if you would use the namespace prefix in you xpath queries).

text-shadow: -1px 0 black, 0 1px black, 1px 0 black, 0 -1px black;

Try this:

select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;

// in C language.. but the algo is same

#include <stdio.h>

int main(){
  float x = 77.6;

  if(x-(int) x>0)
    printf("True! it is float.");
  else
    printf("False! not float.");        

  return 0;
}

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

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

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

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

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

auto lo
iface lo inet loopback

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

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

Maybe because you have a tag like a parent of the tag. That why you have to click two time the images.

For me the solution is this: http://www.w3schools.com/js/tryit.asp?filename=tryjs_intro_lightbulb

You usually get this error if your tables use the InnoDB engine. In that case you would have to drop the foreign key, and then do the alter table and drop the column.

But the tricky part is that you can't drop the foreign key using the column name, but instead you would have to find the name used to index it. To find that, issue the following select:

SHOW CREATE TABLE region;

This should show you the name of the index, something like this:

CONSTRAINT region_ibfk_1 FOREIGN KEY (country_id) REFERENCES country (id) ON DELETE NO ACTION ON UPDATE NO ACTION

Now simply issue an:

alter table region drop foreign key region_ibfk_1;

And finally an:

alter table region drop column country_id;

And you are good to go!

If you only need the bool result, just use the return value and ignore the out parameter.

bool successfullyParsed = int.TryParse(str, out ignoreMe);
if (successfullyParsed){
    // ...
}

Edit: Meanwhile you can also have a look at the original source code:

System.Int32.TryParse

If i want to know how something is actually implemented, i'm using ILSpy to decompile the .NET-code.

This is the result:

// int
/// <summary>Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the operation succeeded.</summary>
/// <returns>true if s was converted successfully; otherwise, false.</returns>
/// <param name="s">A string containing a number to convert. </param>
/// <param name="result">When this method returns, contains the 32-bit signed integer value equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null, is not of the correct format, or represents a number less than <see cref="F:System.Int32.MinValue"></see> or greater than <see cref="F:System.Int32.MaxValue"></see>. This parameter is passed uninitialized. </param>
/// <filterpriority>1</filterpriority>
public static bool TryParse(string s, out int result)
{
    return Number.TryParseInt32(s, NumberStyles.Integer, NumberFormatInfo.CurrentInfo, out result);
}


// System.Number
internal unsafe static bool TryParseInt32(string s, NumberStyles style, NumberFormatInfo info, out int result)
{
    byte* stackBuffer = stackalloc byte[1 * 114 / 1];
    Number.NumberBuffer numberBuffer = new Number.NumberBuffer(stackBuffer);
    result = 0;
    if (!Number.TryStringToNumber(s, style, ref numberBuffer, info, false))
    {
        return false;
    }
    if ((style & NumberStyles.AllowHexSpecifier) != NumberStyles.None)
    {
        if (!Number.HexNumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    else
    {
        if (!Number.NumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    return true;
}

And no, i cannot see any Try-Catchs on the road:

// System.Number

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

For the example given, I prefer the ternary or condition operator (?) for a specific reason: I can clearly see that assigning a is not optional. With a simple example, it's not too hard to scan the if-else block to see that a is assigned in each clause, but imagine several assignments in each clause:

if (i == 0)
{
    a = 10;
    b = 6;
    c = 3;
}
else
{
    a = 5;
    b = 4;
    d = 1;
}

a = (i == 0) ? 10 : 5;
b = (i == 0) ? 6  : 4;
c = (i == 0) ? 3  : 9;
d = (i == 0) ? 12 : 1;

I prefer the latter so that you know you haven't missed an assignment.

The solutions above are completely changed and deprecated. If you want to use CSS modules (assuming you imported css-loaders) and I have been trying to find an answer for this for such a long time and finally did. The default webpack loader is quite different in the new version.

In your webpack, you need to find a part starting with cssRegex and replace it with this;

{
  test: cssRegex,
  exclude: cssModuleRegex,
  use: getStyleLoaders({
      importLoaders: 1,
      modules: true,
      localIdentName: '[name]__[local]__[hash:base64:5]'
  }),
}

How about using a drop-in solution like ShareThis or AddThis? They have similar functionality, so it's quite possible they already solved the problem.

AddThis's code has a huge if/else browser version fork for saving favorites, though, with most branches ending in prompting the user to manually add the favorite themselves, so I am thinking that no such pure JavaScript implementation exists.

Otherwise, if you only need to support IE and Firefox, you have IE's window.externalAddFavorite( ) and Mozilla's window.sidebar.addPanel( ).

If you do not want to create a new row but simply put it in the empty cell then use:

df.columns.name = 'foo'

Otherwise use:

df.index.name = 'foo'

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

The main difference is that Boolean is an object and boolean is an primitive.

• Object default value is null;
• boolean default value is false;

<table cellpadding="pixels"cellspacing="pixels"></table>
<td align="position"valign="position"></td>

cellpadding="length in pixels" ~ The cellpadding attribute, used in the <table> tag, specifies how much blank space to display in between the content of each table cell and its respective border. The value is defined as a length in pixels. Hence, a cellpadding="10" attribute-value pair will display 10 pixels of blank space on all four sides of the content of each cell in that table.

cellspacing="length in pixels" ~ The cellspacing attribute, also used in the <table> tag, defines how much blank space to display in between adjacent table cells and in between table cells and the table border. The value is defined as a length in pixels. Hence, a cellspacing="10" attribute-value pair will horizontally and vertically separate all adjacent cells in the respective table by a length of 10 pixels. It will also offset all cells from the table's frame on all four sides by a length of 10 pixels.

If you want the number to always be positive no matter what you can do this.

function toPositive(n){
    if(n < 0){
        n = n * -1;
    }
    return n;
}
var a = toPositive(2);  // 2
var b = toPositive(-2); // 2

You could also try this, but i don't recommended it:

function makePositive(n){
    return Number((n*-n).toString().replace('-','')); 
}
var a = makePositive(2);  // 2
var b = makePositive(-2); // 2

The problem with this is that you could be changing the number to negative, then converting to string and removing the - from the string, then converting back to int. Which I would guess would take more processing then just using the other function.

I have tested this in php and the first function is faster, but sometimes JS does some crazy things, so I can't say for sure.

Have implemented @Micah 's solution to generate a trendline with a few changes and thought I'd share:

• Coded as a function
• Option for a polynomial trendline (input order=2)
• Function can also just return the coefficient of determination (R^2, input Rval=True)
• More Numpy array optimisations

Code:

def trendline(xd, yd, order=1, c='r', alpha=1, Rval=False):
    """Make a line of best fit"""

    #Calculate trendline
    coeffs = np.polyfit(xd, yd, order)

    intercept = coeffs[-1]
    slope = coeffs[-2]
    power = coeffs[0] if order == 2 else 0

    minxd = np.min(xd)
    maxxd = np.max(xd)

    xl = np.array([minxd, maxxd])
    yl = power * xl ** 2 + slope * xl + intercept

    #Plot trendline
    plt.plot(xl, yl, c, alpha=alpha)

    #Calculate R Squared
    p = np.poly1d(coeffs)

    ybar = np.sum(yd) / len(yd)
    ssreg = np.sum((p(xd) - ybar) ** 2)
    sstot = np.sum((yd - ybar) ** 2)
    Rsqr = ssreg / sstot

    if not Rval:
        #Plot R^2 value
        plt.text(0.8 * maxxd + 0.2 * minxd, 0.8 * np.max(yd) + 0.2 * np.min(yd),
                 '$R^2 = %0.2f$' % Rsqr)
    else:
        #Return the R^2 value:
        return Rsqr

Pushing to the limits corner radius up to get a circle:

    self.btnFoldButton.layer.cornerRadius = self.btnFoldButton.frame.height/2.0;

If button frame is an square it does not matter frame.height or frame.width. Otherwise use the largest of both ones.

Seems like Firebug or whatever Debugger you are using, is not initialized properly. Are you sure Firebug is fully initialized when you try to access the console.log()-method? Check the Console-Tab (if it's set to activated).

Another possibility could be, that you overwrite the console-Object yourself anywhere in the code.

Make an equals check on the keySet() of both HashMaps.

NOTE:

If your Map contains String keys then it is no problem, but if your Map contains objA type keys then you need to make sure that your class objA implements equals().

I had a similar issue when calling the WPF window out of WinForms.

var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
    ElementHost.EnableModelessKeyboardInterop(wpfwindow);
    wpfwindow.Show();

However, showing window as a dialog, it worked

var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
    ElementHost.EnableModelessKeyboardInterop(wpfwindow);
    wpfwindow.ShowDialog();

Hope this helps.

Here is an IIF version with NULL handling (based on of Xin's answer):

IIF(a IS NULL OR b IS NULL, ISNULL(a,b), IIF(a > b, a, b))

The logic is as follows, if either of the values is NULL, return the one that isn't NULL (if both are NULL, a NULL is returned). Otherwise return the greater one.

Same can be done for MIN.

IIF(a IS NULL OR b IS NULL, ISNULL(a,b), IIF(a < b, a, b))

Compound checking:

   if (thing.foo && thing.foo.bar) {
      ... thing.foor.bar exists;
   }

When I was started with express always wanted a solution to use import instead require

const express = require("express");
// to 
import express from "express"

Many time go through this line:- Unfortunately, Node.js doesn't support ES6's import yet.

Now to help other I create new two solutions here

1) esm:-

The brilliantly simple, babel-less, bundle-less ECMAScript module loader. let's make it work

  yarn add esm / npm install esm

create start.js or use your namespace

 require = require("esm")(module/*, options*/)
 // Import the rest of our application.
 module.exports = require('./src/server.js')
 // where server.js is express server start file

Change in your package.josn pass path of start.js

  "scripts": {
    "start": "node start.js",
    "start:dev": "nodemon start.js",
  },
  "dependencies": {
+    "esm": "^3.2.25",
  },
  "devDependencies": {
+   "nodemon": "^1.19.2"
  }

2) Babel js:-

This can be divide into 2 part

a) Solution 1 thanks to timonweb.com

b) Solution 2

use Babel 6 (older version of babel-preset-stage-3 ^6.0) create .babelrc file at your root folder

{
    "presets": ["env", "stage-3"]
}

Install babel-preset-stage-3

yarn add babel-cli babel-polyfill babel-preset-env bable-preset-stage-3 nodemon --dev

Change in package.json

"scripts": {
+   "start:dev": "nodemon --exec babel-node -- ./src/index.js",
+   "start": "npm run build && node ./build/index.js",
+   "build": "npm run clean && babel src -d build -s --source-maps --copy-files",
+   "clean": "rm -rf build && mkdir build"
},
"devDependencies": {
+    "babel-cli": "^6.26.0",
+    "babel-polyfill": "^6.26.0",
+    "babel-preset-env": "^1.7.0",
+    "babel-preset-stage-3": "^6.24.1",
+    "nodemon": "^1.19.4"
},

Start your server

yarn start / npm start

Oooh no we create new problem

regeneratorRuntime.mark(function _callee(email, password) {
^
ReferenceError: regeneratorRuntime is not defined

This error only come when you use async/await in your code. Then use polyfill that includes a custom regenerator runtime and core-js. add on top of index.js

import "babel-polyfill"

This allow you to use async/await

use Babel 7

Need to upto date every thing in your project let start with babel 7 .babelrc

{
  "presets": ["@babel/preset-env"]
}

Some change in package.json

"scripts": {
+  "start:dev": "nodemon --exec babel-node -- ./src/index.js",
+  "start": "npm run build && node ./build/index.js",
+  "build": "npm run clean && babel src -d build -s --source-maps --copy-files",
+  "clean": "rm -rf build && mkdir build",
    ....
}
"devDependencies": {
+   "@babel/cli": "^7.0.0",
+   "@babel/core": "^7.6.4",
+   "@babel/node": "^7.0.0",
+   "@babel/polyfill": "^7.0.0",
+   "@babel/preset-env": "^7.0.0",
+   "nodemon": "^1.19.4"
....
}

and use import "@babel/polyfill" on start point

import "@babel/polyfill"
import express from 'express'
const app = express()

//GET request
app.get('/', async (req, res) {
  // await operation
  res.send('hello world')
})
app.listen(4000, () => console.log(' Server listening on port 400!'))

Are you thinking why start:dev

Seriously. It is good question if you are new. Every change you are boar with start server every time then use yarn start:dev as development server every change restart server automatically for more on nodemon

Since you are in a controller, the action method is given a Request parameter.

You can access all POST data with $request->request->all();. This returns a key-value pair array.

When using GET requests you access data using $request->query->all();

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

On Amazon ec2 with Ubuntu + nginx + php7, I had the same issues, solved it using:

sudo apt-get install php7.0-zip

This should help clear up any questions you may have: C# literals

Here is a table from the linked content:

Regular literal	Verbatim literal	Resulting string
"Hello"	@"Hello"	Hello
"Backslash: \\"	@"Backslash: \"	Backslash: \
"Quote: \""	@"Quote: """	Quote: "
"CRLF:\r\nPost CRLF"	@"CRLF: Post CRLF"	CRLF: Post CRLF

There is a section in the MySQL manual on how to reset the root password which will solve your problem.

For me texBoxName.Clear();is the best method because I have textboxs in binding and if I use other methods I do not have a good day

Working with Git 2.3.2 ...

git branch --set-upstream-to myfork/master

Now status, push and pull are pointed to myfork remote

Please consider the deasync module, personally I don't like the Promise way to make all functions async, and keyword async/await anythere. And I think the official node.js should consider to expose the event loop API, this will solve the callback hell simply. Node.js is a framework not a language.

var node = require("deasync");
node.loop = node.runLoopOnce;

var done = 0;
// async call here
db.query("select * from ticket", (error, results, fields)=>{
    done = 1;
});

while (!done)
    node.loop();

// Now, here you go

The only thing about using telnet to test postfix, or other SMTP, is that you have to know the commands and syntax. Instead, just use swaks :)

It's just one easy command.

My work around for this problem has always been to use the principle that single hash temp tables are in scope to any called procs. So, I have an option switch in the proc parameters (default set to off). If this is switched on, the called proc will insert the results into the temp table created in the calling proc. I think in the past I have taken it a step further and put some code in the called proc to check if the single hash table exists in scope, if it does then insert the code, otherwise return the result set. Seems to work well - best way of passing large data sets between procs.

Try the following to see if you have the proper repository installed:

# yum search java | grep 'java-'

This is going to return a list of available packages that have java in the title. Specifically we are interested in the java- anything, as the jdk will typically be in 'java-version#' type format... Anyhow, if you have to install a repo look at Dag Wieers repo:

http://dag.wieers.com/rpm/FAQ.php#B

After you've got it installed try yum search again... This time you'll have a bunch of java stuff.

# yum search java | grep 'java-'

This will return the list of the available java packages. You can install one like this:

# yum install java-1.7.0-openjdk.x86_64

On Windows 7 one can just open the project folder and do a search for ".svn" if hidden files are enabled and delete all found .svn folders.

You have to be more precise, using parentheses, otherwise Java will not use the order of operands that you want it to use.

if ((a[0] & 1 == 0) && (a[1] & 1== 0) && (a[2] & 1== 0)){

Becomes

if (((a[0] & 1) == 0) && ((a[1] & 1) == 0) && ((a[2] & 1) == 0)){

In OnCreate method of your activity use this code:

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Now your orientation will be set to portrait and will never change.

NODE USERS (REACT,EXPRESS) FOLLOW THESE STEPS

1. npm install base-64 --save
2. import { encode } from "base-64";

3.  const response = await fetch(URL, {
     method: 'post',
     headers: new Headers({
       'Authorization': 'Basic ' + encode(username + ":" + password),
       'Content-Type': 'application/json'
     }),
     body: JSON.stringify({
       "PassengerMobile": "xxxxxxxxxxxx",
       "Password": "xxxxxxx"
     })
   });
   const posts = await response.json();

(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.){3}(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2})))

Test to find matches in text, https://regex101.com/r/9CcMEN/2

Following are the rules defining the valid combinations in each number of an IP address:

• Any one- or two-digit number.

• Any three-digit number beginning with 1.

• Any three-digit number beginning with 2 if the second digit is 0 through 4.

• Any three-digit number beginning with 25 if the third digit is 0 through 5.

Let'start with (((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.), a set of four nested subexpressions, and we’ll look at them in reverse order. (\d{1,2}) matches any one- or two-digit number or numbers 0 through 99. (1\d{2}) matches any three-digit number starting with 1 (1 followed by any two digits), or numbers 100 through 199. (2[0-4]\d) matches numbers 200 through 249. (25[0-5]) matches numbers 250 through 255. Each of these subexpressions is enclosed within another subexpression with an | between each (so that one of the four subexpressions has to match, not all). After the range of numbers comes \. to match ., and then the entire series (all the number options plus \.) is enclosed into yet another subexpression and repeated three times using {3}. Finally, the range of numbers is repeated (this time without the trailing \.) to match the final IP address number. By restricting each of the four numbers to values between 0 and 255, this pattern can indeed match valid IP addresses and reject invalid addresses.

Excerpt From: Ben Forta. “Learning Regular Expressions.”

If neither a character is wanted at the beginning of IP address nor at the end, ^ and $ metacharacters ought to be used, respectively.

^(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.){3}(((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2})))$

100% working

Do some little trick using attribute. In your form add an attribute like data-flag in your form, assign "0" as false.

<form id="from1" data-flag="0">
    //your inputs
</form>

In your javascript:

document.querySelector('#from1').onsubmit = function(e){

    $flag = $(this).attr('data-flag');

    if($flag==0){
        e.preventDefault(); //to prevent submitting

        swal({
            title: "Are you sure?",
            text: "You will not be able to recover this imaginary file!",
            type: "warning",
            showCancelButton: true,
            confirmButtonColor: '#DD6B55',
            confirmButtonText: 'Yes, I am sure!',
            cancelButtonText: "No, cancel it!",
            closeOnConfirm: false,
            closeOnCancel: false
         },
         function(isConfirm){

           if (isConfirm){
                swal("Shortlisted!", "Candidates are successfully shortlisted!", "success");

                //update the data-flag to 1 (as true), to submit
                $('#from1').attr('data-flag', '1');
                $('#from1').submit();
            } else {
                swal("Cancelled", "Your imaginary file is safe :)", "error"); 
            }
         });
    }

    return true;
});

CSS

select.inpSelect {
  //Remove original arrows
  -webkit-appearance: none; 
  //Use png at assets/selectArrow.png for the arrow on the right
  //Set the background color to a BadAss Green color 
  background: url(assets/selectArrow.png) no-repeat right #BADA55;
}

An easy way I'm using:

file_put_contents($output_file, file_get_contents($base64_string));

This works well because file_get_contents can read data from a URI, including a data:// URI.

I met the same problem and I noticed the sample code was put under directory "java" instead of directory "src". After moving the code to src, the problem was solved.

Also make sure the app directory is split into multiple folders. e.g. /main/com/site/appname/ not /main/com.site.appname/

Hope it works~

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

You should look at the article C++ Programming/Type Casting.

It contains a good description of all of the different cast types. The following taken from the above link:

const_cast

const_cast(expression) The const_cast<>() is used to add/remove const(ness) (or volatile-ness) of a variable.

static_cast

static_cast(expression) The static_cast<>() is used to cast between the integer types. 'e.g.' char->long, int->short etc.

Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type.

dynamic_cast

Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy).

dynamic_cast(expression)

The target type must be a pointer or reference type, and the expression must evaluate to a pointer or reference. Dynamic cast works only when the type of object to which the expression refers is compatible with the target type and the base class has at least one virtual member function. If not, and the type of expression being cast is a pointer, NULL is returned, if a dynamic cast on a reference fails, a bad_cast exception is thrown. When it doesn't fail, dynamic cast returns a pointer or reference of the target type to the object to which expression referred.

reinterpret_cast

Reinterpret cast simply casts one type bitwise to another. Any pointer or integral type can be casted to any other with reinterpret cast, easily allowing for misuse. For instance, with reinterpret cast one might, unsafely, cast an integer pointer to a string pointer.

Class org.apache.commons.lang3.CharEncoding.UTF_8 is deprecated after Java 7 introduced java.nio.charset.StandardCharsets

• @see JRE character encoding names
• @since 2.1
• @deprecated Java 7 introduced {@link java.nio.charset.StandardCharsets}, which defines these constants as
• {@link Charset} objects. Use {@link Charset#name()} to get the string values provided in this class.
• This class will be removed in a future release.

Simply follow the code

public static String getFormatedDate(String strDate,StringsourceFormate,
                                     String destinyFormate) {
    SimpleDateFormat df;
    df = new SimpleDateFormat(sourceFormate);
    Date date = null;
    try {
        date = df.parse(strDate);

    } catch (ParseException e) {
        e.printStackTrace();
    }

    df = new SimpleDateFormat(destinyFormate);
    return df.format(date);

}

and pass the value into the function like that,

getFormatedDate("21:30:00", "HH:mm", "hh:mm aa");

or checkout this documentation SimpleDateFormat for StringsourceFormate and destinyFormate.

There is a workaround.

1. Import excel sheet with numbers as float (default).
2. After importing, Goto Table-Design
3. Change DataType of the column from Float to Int or Bigint
4. Save Changes
5. Change DataType of the column from Bigint to any Text Type (Varchar, nvarchar, text, ntext etc)
6. Save Changes.

That's it.

Try to play with

setMinSize()
setMaxSize()
setPreferredSize()

These method are used by layout when it decide what should be the size of current element. The layout manager calls setSize() and actually overrides your values.

As noted by CommonsWare in this question https://stackoverflow.com/a/16064418/1319061, this error can also occur if you are creating an anonymous subclass of a Fragment, since anonymous classes cannot have constructors.

Don't make anonymous subclasses of Fragment :-)

Based on my Comment here is one way to get what you want done:

Start byt selecting any cell in your range and Press Ctrl + T

This will give you this pop up:

make sure the Where is your table text is correct and click ok you will now have:

Now If you add a column header in D it will automatically be added to the table all the way to the last row:

Now If you enter a formula into this column:

After you enter it, the formula will be auto filled all the way to last row:

Now if you add a new row at the next row under your table:

Once entered it will be resized to the width of your table and all columns with formulas will be added also:

Hope this solves your problem!

I want to add another solution: In my case, I need to use a Enum group in a drop down button list items. So they might have space, i.e. more user friendly descriptions needed:

  public enum CancelReasonsEnum
{
    [Description("In rush")]
    InRush,
    [Description("Need more coffee")]
    NeedMoreCoffee,
    [Description("Call me back in 5 minutes!")]
    In5Minutes
}

In a helper class (HelperMethods) I created the following method:

 public static List<string> GetListOfDescription<T>() where T : struct
    {
        Type t = typeof(T);
        return !t.IsEnum ? null : Enum.GetValues(t).Cast<Enum>().Select(x => x.GetDescription()).ToList();
    }

When you call this helper you will get the list of item descriptions.

 List<string> items = HelperMethods.GetListOfDescription<CancelReasonEnum>();

ADDITION: In any case, if you want to implement this method you need :GetDescription extension for enum. This is what I use.

 public static string GetDescription(this Enum value)
    {
        Type type = value.GetType();
        string name = Enum.GetName(type, value);
        if (name != null)
        {
            FieldInfo field = type.GetField(name);
            if (field != null)
            {
                DescriptionAttribute attr =Attribute.GetCustomAttribute(field,typeof(DescriptionAttribute)) as DescriptionAttribute;
                if (attr != null)
                {
                    return attr.Description;
                }
            }
        }
        return null;
        /* how to use
            MyEnum x = MyEnum.NeedMoreCoffee;
            string description = x.GetDescription();
        */

    }

This might help you

In most cases, the system does not relaunch apps after they are force quit by the user. One exception is location apps, which in iOS 8 and later are relaunched after being force quit by the user. In other cases, though, the user must launch the app explicitly or reboot the device before the app can be launched automatically into the background by the system. When password protection is enabled on the device, the system does not launch an app in the background before the user first unlocks the device.

If this doesn't work it may be overridden by your current settings. You can right-click in the bar to the left of the code where line numbers would normally appear and turn them on with the context menu.

Here's what I've learned as I determine the best way to move forward with a couple of my current app projects.

Async Storage (formerly "built-in" to React Native, now moved on its own)

I use AsyncStorage for an in-production app. Storage stays local to the device, is unencrypted (as mentioned in another answer), goes away if you delete the app, but should be saved as part of your device's backups and persists during upgrades (both native upgrades ala TestFlight and code upgrades via CodePush).

Conclusion: Local storage; you provide your own sync/backup solution.

SQLite

Other projects I have worked on have used sqlite3 for app storage. This gives you an SQL-like experience, with compressible databases that can also be transmitted to and from the device. I have not had any experience with syncing them to a back end, but I imagine various libraries exist. There are RN libraries for connecting to SQLite.

Data is stored in your traditional database format with databases, tables, keys, indices, etc. all saved to disk in a binary format. Direct access to the data is available via command line or apps that have SQLite drivers.

Conclusion: Local storage; you supply the sync and backup.

Firebase

Firebase offers, among other things, a real time noSQL database along with a JSON document store (like MongoDB) meant for keeping from 1 to n number of clients synchronized. The docs talk about offline persistence, but only for native code (Swift/Obj-C, Java). Google's own JavaScript option ("Web") which is used by React Native does not provide a cached storage option (see 2/18 update below). The library is written with the assumption that a web browser is going to be connecting, and so there will be a semi-persistent connection. You could probably write a local caching mechanism to supplement the Firebase storage calls, or you could write a bridge between the native libraries and React Native.

Update 2/2018 I have since found React Native Firebase which provides a compatible JavaScript interface to the native iOS and Android libraries (doing what Google probably could/should have done), giving you all the goodies of the native libraries with the bonus of React Native support. With Google's introduction of a JSON document store beside the real-time database, I'm giving Firebase a good second look for some real-time apps I plan to build.

The real-time database is stored as a JSON-like tree that you can edit on the website and import/export pretty simply.

Conclusion: With react-native-firebase, RN gets same benefits as Swift and Java. [/update] Scales well for network-connected devices. Low cost for low utilization. Combines nicely with other Google cloud offerings. Data readily visible and editable from their interface.

Realm

Update 4/2020 MongoDB has acquired Realm and is planning to combine it with MongoDB Stitch (discussed below). This looks very exciting.

Update 9/2020 Having used Realm vs. Stitch: Stitch API's essentially allowed a JS app (React Native or web) to talk directly to the Mongo database instead of going through an API server you build yourself.

Realm was meant to synchronize portions of the database whenever changes were made.

The combination of the two gets a little confusing. The formerly-known-as-Stitch API's still work like your traditional Mongo query and update calls, whereas the newer Realm stuff attaches to objects in code and handles synchronization all by itself... mostly. I'm still working through the right way to do things in one project, which is using SwiftUI, so it's a bit off-topic. But promising and neat nonetheless.

Also a real time object store with automagic network synchronization. They tout themselves as "device first" and the demo video shows how the devices handle sporadic or lossy network connectivity.

They offer a free version of the object store that you host on your own servers or in a cloud solution like AWS or Azure. You can also create in-memory stores that do not persist with the device, device-only stores that do not sync up with the server, read-only server stores, and the full read-write option for synchronization across one or more devices. They have professional and enterprise options that cost more up front per month than Firebase.

Unlike Firebase, all Realm capabilities are supported in React Native and Xamarin, just as they are in Swift/ObjC/Java (native) apps.

Your data is tied to objects in your code. Because they are defined objects, you do have a schema, and version control is a must for code sanity. Direct access is available via GUI tools Realm provides. On-device data files are cross-platform compatible.

Conclusion: Device first, optional synchronization with free and paid plans. All features supported in React Native. Horizontal scaling more expensive than Firebase.

iCloud

I honestly haven't done a lot of playing with this one, but will be doing so in the near future.

If you have a native app that uses CloudKit, you can use CloudKit JS to connect to your app's containers from a web app (or, in our case, React Native). In this scenario, you would probably have a native iOS app and a React Native Android app.

Like Realm, this stores data locally and syncs it to iCloud when possible. There are public stores for your app and private stores for each customer. Customers can even chose to share some of their stores or objects with other users.

I do not know how easy it is to access the raw data; the schemas can be set up on Apple's site.

Conclusion: Great for Apple-targeted apps.

Couchbase

Big name, lots of big companies behind it. There's a Community Edition and Enterprise Edition with the standard support costs.

They've got a tutorial on their site for hooking things up to React Native. I also haven't spent much time on this one, but it looks to be a viable alternative to Realm in terms of functionality. I don't know how easy it is to get to your data outside of your app or any APIs you build.

[Edit: Found an older link that talks about Couchbase and CouchDB, and CouchDB may be yet another option to consider. The two are historically related but presently completely different products. See this comparison.]

Conclusion: Looks to have similar capabilities as Realm. Can be device-only or synced. I need to try it out.

MongoDB

Update 4/2020

Mongo acquired Realm and plans to combine MongoDB Stitch (discussed below) with Realm (discussed above).

I'm using this server side for a piece of the app that uses AsyncStorage locally. I like that everything is stored as JSON objects, making transmission to the client devices very straightforward. In my use case, it's used as a cache between an upstream provider of TV guide data and my client devices.

There is no hard structure to the data, like a schema, so every object is stored as a "document" that is easily searchable, filterable, etc. Similar JSON objects could have additional (but different) attributes or child objects, allowing for a lot of flexibility in how you structure your objects/data.

I have not tried any client to server synchronization features, nor have I used it embedded. React Native code for MongoDB does exist.

Conclusion: Local only NoSQL solution, no obvious sync option like Realm or Firebase.

Update 2/2019

MongoDB has a "product" (or service) called Stitch. Since clients (in the sense of web browsers and phones) shouldn't be talking to MongoDB directly (that's done by code on your server), they created a serverless front-end that your apps can interface with, should you choose to use their hosted solution (Atlas). Their documentation makes it appear that there is a possible sync option.

This writeup from Dec 2018 discusses using React Native, Stitch, and MongoDB in a sample app, with other samples linked in the document (https://www.mongodb.com/blog/post/building-ios-and-android-apps-with-the-mongodb-stitch-react-native-sdk).

Twilio Sync

Another NoSQL option for synchronization is Twilio's Sync. From their site: "Sync lets you manage state across any number of devices in real time at scale without having to handle any backend infrastructure."

I looked at this as an alternative to Firebase for one of the aforementioned projects, especially after talking to both teams. I also like their other communications tools, and have used them for texting updates from a simple web app.

[Edit] I've spent some time with Realm since I originally wrote this. I like how I don't have to write an API to sync the data between the app and the server, similar to Firebase. Serverless functions also look to be really helpful with these two, limiting the amount of backend code I have to write.

I love the flexibility of the MongoDB data store, so that is becoming my choice for the server side of web-based and other connection-required apps.

I found RESTHeart, which creates a very simple, scalable RESTful API to MongoDB. It shouldn't be too hard to build a React (Native) component that reads and writes JSON objects to RESTHeart, which in turn passes them to/from MongoDB.

[Edit] I added info about how the data is stored. Sometimes it's important to know how much work you might be in for during development and testing if you've got to tweak and test the data.

Edits 2/2019 I experimented with several of these options when designing a high-concurrency project this past year (2018). Some of them mention hard and soft concurrency limits in their documentation (Firebase had a hard one at 10,000 connections, I believe, while Twilio's was a soft limit that could be bumped, according to discussions with both teams at AltConf).

If you are designing an app for tens to hundreds of thousands of users, be prepared to scale the data backend accordingly.

The following snippet shows an example, which can archive a throughput of 400 MB/s while reading and hashing the file.

It is using a library called hash-wasm, which is based on WebAssembly and calculates the hash faster than js-only libraries. As of 2020, all modern browsers support WebAssembly.

const chunkSize = 64 * 1024 * 1024;
const fileReader = new FileReader();
let hasher = null;

function hashChunk(chunk) {
  return new Promise((resolve, reject) => {
    fileReader.onload = async(e) => {
      const view = new Uint8Array(e.target.result);
      hasher.update(view);
      resolve();
    };

    fileReader.readAsArrayBuffer(chunk);
  });
}

const readFile = async(file) => {
  if (hasher) {
    hasher.init();
  } else {
    hasher = await hashwasm.createMD5();
  }

  const chunkNumber = Math.floor(file.size / chunkSize);

  for (let i = 0; i <= chunkNumber; i++) {
    const chunk = file.slice(
      chunkSize * i,
      Math.min(chunkSize * (i + 1), file.size)
    );
    await hashChunk(chunk);
  }

  const hash = hasher.digest();
  return Promise.resolve(hash);
};

const fileSelector = document.getElementById("file-input");
const resultElement = document.getElementById("result");

fileSelector.addEventListener("change", async(event) => {
  const file = event.target.files[0];

  resultElement.innerHTML = "Loading...";
  const start = Date.now();
  const hash = await readFile(file);
  const end = Date.now();
  const duration = end - start;

I'll explain the main use cases of implicits below, but for more detail see the relevant chapter of Programming in Scala.

Implicit parameters

The final parameter list on a method can be marked implicit, which means the values will be taken from the context in which they are called. If there is no implicit value of the right type in scope, it will not compile. Since the implicit value must resolve to a single value and to avoid clashes, it's a good idea to make the type specific to its purpose, e.g. don't require your methods to find an implicit Int!

example:

  // probably in a library
class Prefixer(val prefix: String)
def addPrefix(s: String)(implicit p: Prefixer) = p.prefix + s

  // then probably in your application
implicit val myImplicitPrefixer = new Prefixer("***")
addPrefix("abc")  // returns "***abc"

Implicit conversions

When the compiler finds an expression of the wrong type for the context, it will look for an implicit Function value of a type that will allow it to typecheck. So if an A is required and it finds a B, it will look for an implicit value of type B => A in scope (it also checks some other places like in the B and A companion objects, if they exist). Since defs can be "eta-expanded" into Function objects, an implicit def xyz(arg: B): A will do as well.

So the difference between your methods is that the one marked implicit will be inserted for you by the compiler when a Double is found but an Int is required.

implicit def doubleToInt(d: Double) = d.toInt
val x: Int = 42.0

will work the same as

def doubleToInt(d: Double) = d.toInt
val x: Int = doubleToInt(42.0)

In the second we've inserted the conversion manually; in the first the compiler did the same automatically. The conversion is required because of the type annotation on the left hand side.

Regarding your first snippet from Play:

Actions are explained on this page from the Play documentation (see also API docs). You are using

apply(block: (Request[AnyContent]) ? Result): Action[AnyContent]

on the Action object (which is the companion to the trait of the same name).

So we need to supply a Function as the argument, which can be written as a literal in the form

request => ...

In a function literal, the part before the => is a value declaration, and can be marked implicit if you want, just like in any other val declaration. Here, request doesn't have to be marked implicit for this to type check, but by doing so it will be available as an implicit value for any methods that might need it within the function (and of course, it can be used explicitly as well). In this particular case, this has been done because the bindFromRequest method on the Form class requires an implicit Request argument.

EDIT: This is not working with latest version of 63.0+

I was able to disable it using help from one of above comments, go to

chrome://flags/#enable-webfonts-intervention-v2

The trick is to also disable the "Trigger User Agent Intervention for WebFonts loading always" option just below that as well.

Just want to mention that pdub's GOTO solution is not fully correct in case :comment label appear in multiple times. I modify the code from this question as the example.

@ECHO OFF
SET FLAG=1
IF [%FLAG%]==[1] (
    ECHO IN THE FIRST IF...
    GOTO comment
    ECHO "COMMENT PART 1"
:comment
    ECHO HERE AT TD_NEXT IN THE FIRST BLOCK
)

IF [%FLAG%]==[1] (
    ECHO IN THE SECOND IF...
    GOTO comment
    ECHO "COMMENT PART"
:comment
    ECHO HERE AT TD_NEXT IN THE SECOND BLOCK
)

The output will be

IN THE FIRST IF...
HERE AT TD_NEXT IN THE SECOND BLOCK

The command ECHO HERE AT TD_NEXT IN THE FIRST BLOCK is skipped.

Use mathematics first find square root of number then start loop till the number ends which you get after square rooting. check for each value whether the given number is divisible by the iterating value .if any value divides the given number then it is not a prime number otherwise prime. Here is the code

 bool is_Prime(int n)
 {

   int square_root = sqrt(n); // use math.h
   int toggle = 1;
   for(int i = 2; i <= square_root; i++)
   {
     if(n%i==0)
     { 
        toggle = 0;
        break;
     }
   }

   if(toggle)
     return true;
   else
     return false;

 } 

First at all i'm seing your code and you haven't any controller. So i suggest that you use a controller. I think you have to use a controller because your variable {{myStyle}} isn't compile because the 2 curly brace are visible and they shouldn't.

Second you have to use ng-model for your input, this directive will bind the value of the input to your variable.

The original request has been answered already.

However, I am posting the below answer for those who might be looking for generic transliteration code to transliterate any charset to Latin/English in Java.

Naive meaning of tranliteration: Translated string in it's final form/target charset sounds like the string in it's original form. If we want to transliterate any charset to Latin(English alphabets), then ICU4(ICU4J library in java ) will do the job.

Here is the code snippet in java:

    import com.ibm.icu.text.Transliterator; //ICU4J library import

    public static String TRANSLITERATE_ID = "NFD; Any-Latin; NFC";
    public static String NORMALIZE_ID = "NFD; [:Nonspacing Mark:] Remove; NFC";

    /**
    * Returns the transliterated string to convert any charset to latin.
    */
    public static String transliterate(String input) {
        Transliterator transliterator = Transliterator.getInstance(TRANSLITERATE_ID + "; " + NORMALIZE_ID);
        String result = transliterator.transliterate(input);
        return result;
    }

It is meaningless to talk about TCP or UDP without taking the network condition into account. If the network between the two point have a very high quality, UDP is absolutely faster than TCP, but in some other case such as the GPRS network, TCP may been faster and more reliability than UDP.

*ngIf removes the element from the DOM when the expression becomes false. You can't have a transition on a non-existing element.

Use instead hidden:

Also, you can utilize crash dumps to debug your software. The customer sends it to you and then you can use it to identify the exact version of your source - and Visual Studio will even pull the right set of debugging symbols (and source if you're set up correctly) using the crash dump. See Microsoft's documentation on Symbol Stores.

When it comes to applications that run on a server, including web sites and other back-end services, the time zone setting of the server should be ignored by the application.

The common advice is to set the server's time zone to UTC. This is indeed a good best practice, but it's there as a band-aid for applications that do not follow other best practices. For example, a service might be writing to log files with local timestamps instead of UTC-based timestamps, thus creating ambiguities during the daylight saving time fall-back transition. Setting the server's time zone to UTC will fix that application. However the real fix would be for the application to log using UTC to begin with.

Server-side code, including web sites, should never expect the local time zone of the server to be anything in particular.

In some languages, the local time zone can easily creep in to application code. For example, the DateTime.ToUniversalTime method in .NET will convert from the local time zone to UTC, and the DateTime.Now property returns the current time in the local time zone. Also, the Date constructor in JavaScript uses the computer's local time zone. There are many other examples like this. It is important to practice defensive programming, avoiding any code that uses the computer's local time zone setting.

Reserve using the local time zone for client-side code, such as desktop applications, mobile applications, and client-side JavaScript.

The problem occurs in declaring context, while using Glide for ImageView or While using intent in recyclerview for item onClick. I Found this working for me which helps me to Declare context to use in Glide or Intent or Toast.

public class NoteAdapter extends FirestoreRecyclerAdapter<Note,NoteAdapter.NoteHolder> {

Context context;

public NoteAdapter(@NonNull FirestoreRecyclerOptions<Note> options) {
    super(options);
}

@Override
protected void onBindViewHolder(@NonNull NoteHolder holder, int position, @NonNull Note model) {
    holder.r_tv.setText(model.getTitle());
    Glide.with(CategoryActivity.context).load(model.getImage()).into(holder.r_iv);

    context = holder.itemView.getContext();

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(context, SuggestActivity.class);
            context.startActivity(i);
        }
    });

}

@NonNull
@Override
public NoteHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_category,parent,false);

    return new NoteHolder(v);
}

public static class NoteHolder extends RecyclerView.ViewHolder
{
    TextView r_tv;
    ImageView r_iv;

    public NoteHolder(@NonNull View itemView) {
        super(itemView);

        r_tv = itemView.findViewById(R.id.r_tv);
        r_iv = itemView.findViewById(R.id.r_iv);


    }
}
}

I had exactly the same error message. In my case, making an entry in my /etc/hosts file (on the server hosting the service) for the target server referenced in the WSDL fixed it.

Kind of a strangely worded error message..

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)

Here is a slightly concised edition of what Jason suggested:

DateTime? d; DateTime dt;
d = DateTime.TryParse(DateTime.Now.ToString(), out dt)? dt : (DateTime?)null;

If it supports standard regex...

find:
^.*#RedirectMatch Permanent.*$

replace:

Replace with nothing.

The usual way to do it is as outlined by Guffa, nested elements. It's a bit sad having to add extra markup to get the hooks you need for this, but in practice a wrapper div here or there isn't going to hurt anyone.

If you must do it without extra elements (eg. when you don't have control of the page markup), you can use box-sizing, which has pretty decent but not complete or simple browser support. Likely more fun than having to rely on scripting though.

$listOfUsernames = @("user1", "user2", "etc", "and so on")
Get-EventLog -LogName Security | 
    where { $_.Username -notmatch (
        '(' + [string]::Join(')|(', $listOfUsernames) + ')') }

It's a little crazy I'll grant you, and it fails to escape the usernames (in the unprobable case a username uses a Regex escape character like '\' or '(' ), but it works.

As "slipsec" mentioned above, use -notcontains if possible.

If you have Xcode 4 Build Location setting set to "Place build products in derived data location (recommended), it should be located in ~/Library/Developer/Xcode/DerivedData. This directory will have your project in there as a directory, the project name will be appended with a bunch of generated letters so look carefully.

Many others have failed to point out the real issue:

An operation on only integers casts the result of the operation to an integer.

This necessarily means that floating point results, that could be displayed as an integer, will be truncated (lop off the decimal part).

What is casting (typecasting / type conversion) you ask?

It varies on the implementation of the language, but Wikipedia has a fairly comprehensive view, and it does talk about coercion as well, which is a pivotal piece of information in answering your question.

In my case form Data was data , fire base was expecting an object but data contains object as well as all other stuffs so i tried data.value it worked!!!

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.

I recommend using this:

1. Retrieve the father Intent.

   Intent intentParent = getIntent();
   

2. Convey the message directly.

   setResult(RESULT_OK, intentParent);
   

This prevents the loss of its activity which would generate a null data error.

If you were running a 64 bit platform you would see x86_64 or something very similar in the output from uname -a

To get your specific machine hardware name run

uname -m

You can also call

getconf LONG_BIT

which returns either 32 or 64

This happens because your click handler fires before the value of the radio button changes. You need to listen to the change event instead:

<input 
  type="radio" 
  name="optionsRadios" 
  id="optionsRadios2" 
  value=""
  v-model="srStatus" 
  v-on:change="foo"> //here

Also, make sure you really want to call foo() on ready... seems like maybe you don't actually want to do that.

ready:function(){
    foo();
},

I haven't tried it, but iOS WebKit debug proxy (ios_webkit_debug_proxy / iwdp) supposedly lets you remotely debug UIWebView. From the README.md

The ios_webkit_debug_proxy (aka iwdp) allows developers to inspect MobileSafari and UIWebViews on real and simulated iOS devices via the Chrome DevTools UI and Chrome Remote Debugging Protocol. DevTools requests are translated into Apple's Remote Web Inspector service calls.

I had that problem on code pen, and it turn out it's just because I was loading JQuery before Angular. Don't know if that can apply for other cases.

For any method in a Spring CrudRepository you should be able to specify the @Query yourself. Something like this should work:

@Query( "select o from MyObject o where inventoryId in :ids" )
List<MyObject> findByInventoryIds(@Param("ids") List<Long> inventoryIdList);

Try replacing your meta tag with this below:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' http://* 'unsafe-inline'; script-src 'self' http://* 'unsafe-inline' 'unsafe-eval'" />

Or in addition to what you have, you should add http://* to both style-src and script-src as seen above added after 'self'.

If your server is including the Content-Security-Policy header, the header will override the meta.

findIndex works for modern browsers:

var myArr = [{id:'a'},{id:'myid'},{id:'c'}];
var index = myArr.findIndex(function(o){
  return o.id === 'myid';
})
if (index !== -1) myArr.splice(index, 1);

I used this a little example and it worked.

$('#date').datetimepicker({
    defaultDate: new Date()
});

Damien_The_Unbeliever noted that his was only good for digits

Wade73 added a bit to handle decimal points

neizan made an additional tweak as did notwhereuareat

Unfortunately, none appear to handle negative values and they appear to have issues with a comma in the value...

Here's my tweak to pick up negative values and those with commas

declare @MyTable table(MyVar nvarchar(10));
insert into @MyTable (MyVar) 
values 
(N'1234')
, (N'000005')
, (N'1,000')
, (N'293.8457')
, (N'x')
, (N'+')
, (N'293.8457.')
, (N'......')
, (N'.')
, (N'-375.4')
, (N'-00003')
, (N'-2,000')
, (N'3-3')
, (N'3000-')
;

-- This shows that Neizan's answer allows "." to slip through.
select * from (
select 
    MyVar
    , case when MyVar not like N'%[^0-9.]%' then 1 else 0 end as IsNumber 
from 
    @MyTable
) t order by IsNumber;

-- Notice the addition of "and MyVar not like '.'".
select * from (
select 
    MyVar
    , case when MyVar not like N'%[^0-9.]%' and MyVar not like N'%.%.%' and MyVar not like '.' then 1 else 0 end as IsNumber 
from 
    @MyTable
) t 
order by IsNumber;

--Trying to tweak for negative values and the comma
--Modified when comparison
select * from (
select 
    MyVar
    , case 
        when MyVar not like N'%[^0-9.,-]%' and MyVar not like '.' and isnumeric(MyVar) = 1 then 1
        else 0 
    end as IsNumber 
from 
    @MyTable
) t 
order by IsNumber;

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)

Also, your method is always returning a string in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value))

I have done with below single git command:

git clone [url] -b [branch-name] --single-branch

Completeness

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

Even the first answer is absolutely brilliant, you probably want to only run script under sudo.

You have to specify the absolute path like:

sudo /home/user/example.sh
sudo ~/example.sh

(both are working)

THIS WONT WORK!

sudo /bin/sh example.sh
sudo example.sh

It will always return

sudo: bin/sh: command not found
sudo: example.sh: command not found

I think it is a bug.

Try adjust height not by Utility inspector but by mouse drag on the storyboard directly.

I solved this problem with this method.

Hold on...

From my experience, you SHOULD make sure that the DocumCompleted belongs to YOUR URL and not to a frame sub-page, script, image, CSS, etc. And that is regardless of the IsBusy or the ReadyState is finished or not, which both are often inaccurate when page is slightly complex.

Well, that is my own personal experience, on a working program of VB.2013 and IE11. Let me also mention that you should take into account also the compatibility mode IE7 which is ON by default at the webBrowser1.

' Page, sub-frame or resource was totally loaded.
Private Sub webBrowser1_DocumentCompleted(sender As Object, _ 
    e As WebBrowserDocumentCompletedEventArgs) _ 
    Handles webBrowser1.DocumentCompleted

    ' Check if finally the full page was loaded (inc. sub-frames, javascripts, etc)
    If e.Url.ToString = webBrowser1.Url.ToString Then
        ' Only now you are sure!
        fullyLoaded = True
    End If

End Sub

Just to be different:

MOREF=$(sudo run command against $VAR1 | grep name | cut -c7-)

I arrived here like most people with this same issue, and left shocked that none of the answer even remotely worked.

For anyone interested, here is the actual solution:

... //rest of options
width: '100%',
height: '350',
chartArea:{
    left:5,
    top: 20,
    width: '100%',
    height: '350',
}
... //rest of options

The key here has nothing to do with the "left" or "top" values. But rather that the:

Dimensions of both the chart and chart-area are SET and set to the SAME VALUE

As an amendment to my answer. The above will indeed solve the "excessive" padding/margin/whitespace problem. However, if you wish to include axes labels and/or a legend you will need to reduce the height & width of the chart area so something slightly below the outer width/height. This will "tell" the chart API that there is sufficient room to display these properties. Otherwise it will happily exclude them.

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

When using Date and Time values, you must cast the fields as DateTime and not Date. Try :

SELECT * FROM `objects` 
WHERE (CAST(date_field AS DATETIME) 
BETWEEN CAST('2010-09-29 10:15:55' AS DATETIME) AND CAST('2010-01-30 14:15:55' AS DATETIME))

Maybe placing the jquery.ui.widget.js as second after jquery.ui.core.js.

As a one-liner function:

def is_leap_year(year):
    """Determine whether a year is a leap year."""

    return year % 4 == 0 and (year % 100 != 0 or year % 400 == 0)

It's similar to the Mark's answer, but short circuits at the first test (note the parenthesis).

Alternatively, you can use the standard library's calendar.isleap, which has exactly the same implementation:

from calendar import isleap
print(isleap(1900))

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {
    MediaPlayer mp;
    Button one;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mp = MediaPlayer.create(this, R.raw.soho);
        one = (Button)this.findViewById(R.id.button1);

        one.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                mp.start();

        });

}

You could use a regular expression such as the following:

/([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/

So for example:

$s = "abc-456-hu5t10 (High priority) *";
$s =~ /([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/;
print "$1\n$2\n$3\n";

prints

abc-456-hu5t10
High priority
*

.Net Core Solution

Handles null situation and does not throw an exception, but returns true if no value is presented; otherwise takes the inputted Boolean and reverses it.

public class BooleanToReverseConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
     => !(bool?) value ?? true;

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
     => !(value as bool?);
}

Xaml

IsEnabled="{Binding IsSuccess Converter={StaticResource BooleanToReverseConverter}}"

App.Xaml I like to put all my converter statics in the app.xaml file so I don't have to redeclare them throughout the windows/pages/controls of the project.

<Application.Resources>
    <converters:BooleanToReverseConverter x:Key="BooleanToReverseConverter"/>
    <local:FauxVM x:Key="VM" />
</Application.Resources>

To be clear converters: is the namespace to the actual class implementation (xmlns:converters="clr-namespace:ProvingGround.Converters").

The complement of a regular language is also a regular language, but to construct it you have to build the DFA for the regular language, and make any valid state change into an error. See this for an example. What the page doesn't say is that it converted /(ac|bd)/ into /(a[^c]?|b[^d]?|[^ab])/. The conversion from a DFA back to a regular expression is not trivial. It is easier if you can use the regular expression unchanged and change the semantics in code, like suggested before.

For those of you want to copy the cURL output in the clipboard instead of outputting to a file, you can use pbcopy by using the pipe | after the cURL command.

Example: curl https://www.google.com/robots.txt | pbcopy. This will copy all the content from the given URL to your clipboard.

A straight, jagged version of 1d Perlin, essentially a random lfo zigzag.

half  rn(float xx){         
    half x0=floor(xx);
    half x1=x0+1;
    half v0 = frac(sin (x0*.014686)*31718.927+x0);
    half v1 = frac(sin (x1*.014686)*31718.927+x1);          

    return (v0*(1-frac(xx))+v1*(frac(xx)))*2-1*sin(xx);
}

I also have found 1-2-3-4d perlin noise on shadertoy owner inigo quilez perlin tutorial website, and voronoi and so forth, he has full fast implementations and codes for them.
