I ran into the same issue using a COM class, i.e. 'Class not registered exception' at runtime. For me I was able to resolve by going to the app.config file and change the 'startup' and 'supportedRuntime' elements to something like:

<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
  </startup>
</configuration>

Like Query would be as shown below

db.movies.find({title: /.*Twelve Monkeys.*/}).sort({regularizedCorRelation : 1}).limit(10);

for scala ReactiveMongo api,

val query = BSONDocument("title" -> BSONRegex(".*"+name+".*", "")) //like
val sortQ = BSONDocument("regularizedCorRelation" -> BSONInteger(1))
val cursor = collection.find(query).sort(sortQ).options(QueryOpts().batchSize(10)).cursor[BSONDocument]

Let me address your question about "modes." AES256 is a kind of block cipher. It takes as input a 32-byte key and a 16-byte string, called the block and outputs a block. We use AES in a mode of operation in order to encrypt. The solutions above suggest using CBC, which is one example. Another is called CTR, and it's somewhat easier to use:

from Crypto.Cipher import AES
from Crypto.Util import Counter
from Crypto import Random

# AES supports multiple key sizes: 16 (AES128), 24 (AES192), or 32 (AES256).
key_bytes = 32

# Takes as input a 32-byte key and an arbitrary-length plaintext and returns a
# pair (iv, ciphtertext). "iv" stands for initialization vector.
def encrypt(key, plaintext):
    assert len(key) == key_bytes

    # Choose a random, 16-byte IV.
    iv = Random.new().read(AES.block_size)

    # Convert the IV to a Python integer.
    iv_int = int(binascii.hexlify(iv), 16) 

    # Create a new Counter object with IV = iv_int.
    ctr = Counter.new(AES.block_size * 8, initial_value=iv_int)

    # Create AES-CTR cipher.
    aes = AES.new(key, AES.MODE_CTR, counter=ctr)

    # Encrypt and return IV and ciphertext.
    ciphertext = aes.encrypt(plaintext)
    return (iv, ciphertext)

# Takes as input a 32-byte key, a 16-byte IV, and a ciphertext, and outputs the
# corresponding plaintext.
def decrypt(key, iv, ciphertext):
    assert len(key) == key_bytes

    # Initialize counter for decryption. iv should be the same as the output of
    # encrypt().
    iv_int = int(iv.encode('hex'), 16) 
    ctr = Counter.new(AES.block_size * 8, initial_value=iv_int)

    # Create AES-CTR cipher.
    aes = AES.new(key, AES.MODE_CTR, counter=ctr)

    # Decrypt and return the plaintext.
    plaintext = aes.decrypt(ciphertext)
    return plaintext

(iv, ciphertext) = encrypt(key, 'hella')
print decrypt(key, iv, ciphertext)

This is often referred to as AES-CTR. I would advise caution in using AES-CBC with PyCrypto. The reason is that it requires you to specify the padding scheme, as exemplified by the other solutions given. In general, if you're not very careful about the padding, there are attacks that completely break encryption!

Now, it's important to note that the key must be a random, 32-byte string; a password does not suffice. Normally, the key is generated like so:

# Nominal way to generate a fresh key. This calls the system's random number
# generator (RNG).
key1 = Random.new().read(key_bytes)

A key may be derived from a password, too:

# It's also possible to derive a key from a password, but it's important that
# the password have high entropy, meaning difficult to predict.
password = "This is a rather weak password."

# For added # security, we add a "salt", which increases the entropy.
#
# In this example, we use the same RNG to produce the salt that we used to
# produce key1.
salt_bytes = 8 
salt = Random.new().read(salt_bytes)

# Stands for "Password-based key derivation function 2"
key2 = PBKDF2(password, salt, key_bytes)

Some solutions above suggest using SHA256 for deriving the key, but this is generally considered bad cryptographic practice. Check out wikipedia for more on modes of operation.

This explains the whole thing:

The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.

The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.

The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.

According to Wikipedia, the new rupee sign hasn't been added to Unicode yet (U+20B9 ₹ was added to Unicode in late 2010), so you can't use it from HTML. The old (unofficial) symbol is ₨ — ₨.

This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.

I do not have experience with version 7 of JBoss but with 5 I often had issues when redeploying apps which went away when I cleaned the work and tmp folder. I wrote a script for that which was executed everytime the server shut down. Maybe executing it before startup is better considering abnormal shutdowns (which weren't uncommon with Jboss 5 :))

I usually implement a service layer in between views and models. This acts like your project's API and gives you a good helicopter view of what is going on. I inherited this practice from a colleague of mine that uses this layering technique a lot with Java projects (JSF), e.g:

models.py

class Book:
   author = models.ForeignKey(User)
   title = models.CharField(max_length=125)

   class Meta:
       app_label = "library"

services.py

from library.models import Book

def get_books(limit=None, **filters):
    """ simple service function for retrieving books can be widely extended """
    return Book.objects.filter(**filters)[:limit]  # list[:None] will return the entire list

views.py

from library.services import get_books

class BookListView(ListView):
    """ simple view, e.g. implement a _build and _apply filters function """
    queryset = get_books()

Mind you, I usually take models, views and services to module level and separate even further depending on the project's size

var count=30;

var counter=setInterval(timer, 1000); //1000 will  run it every 1 second

function timer()
{
  count=count-1;
  if (count <= 0)
  {
     clearInterval(counter);
     //counter ended, do something here
     return;
  }

  //Do code for showing the number of seconds here
}

To make the code for the timer appear in a paragraph (or anywhere else on the page), just put the line:

<span id="timer"></span>

where you want the seconds to appear. Then insert the following line in your timer() function, so it looks like this:

function timer()
{
  count=count-1;
  if (count <= 0)
  {
     clearInterval(counter);
     return;
  }

 document.getElementById("timer").innerHTML=count + " secs"; // watch for spelling
}

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")

I ended her with the same problem and I could not use the the solution with onEditorAction or onFocusChange and did not want to try the timer. A timer is too dangerous for may taste, because of all the threads and too unpredictable, as you do not know when you code is executed.

The onEditorAction do not catch when the user leave without using a button and if you use it please notice that KeyEvent can be null. The focus is unreliable at both ends the user can get focus and leave without enter any text or selecting the field and the user do not need to leave the last EditText field.

My solution use onFocusChange and a flag set when the user starts editing text and a function to get the text from the last focused view, which I call when need.

I just clear the focus on all my text fields to tricker the leave text view code, The clearFocus code is only executed if the field has focus. I call the function in onSaveInstanceState so I do not have to save the flag (mEditing) as a state of the EditText view and when important buttons is clicked and when the activity is closed.

Be careful with TexWatcher as it is call often I use the condition on focus to not react when the onRestoreInstanceState code entering text. I

final EditText mEditTextView = (EditText) getView();

    mEditTextView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            if (!mEditing && mEditTextView.hasFocus()) {
                mEditing = true;
            }
        }
    });
    mEditTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus && mEditing) {
                mEditing = false;
                ///Do the thing
            }
        }
    });
protected void saveLastOpenField(){
    for (EditText view:getFields()){
            view.clearFocus();
    }
}

You can put them into a list and then sort them using their natural ordering, like so:

final List<Integer> list = Arrays.asList(11367, 11358, 11421, 11530, 11491, 11218, 11789);
Collections.sort( list );
// Use the sorted list

If the numbers are stored in the same variable, then you'll have to somehow put them into a List and then call sort, like so:

final List<Integer> list = new ArrayList<Integer>();
list.add( myVariable );
// Change myVariable to another number...
list.add( myVariable );
// etc...

Collections.sort( list );
// Use the sorted list

• Collections.sort( List )

The solution that worked for me: If you have Sqldeveloper with java incorporated, you can use the \sqldeveloper\bin\sqldeveloper.bat to launch sqldeveloper as told here.

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `dateCreated` datetime DEFAULT CURRENT_TIMESTAMP,
  `dateUpdated` datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  UNIQUE KEY `mobile_UNIQUE` (`mobile`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

The best way is not to write any initializing statements. This is because if you write int a[]=new int[3] then by default, in Java all the values of array i.e. a[0], a[1] and a[2] are initialized to 0! Regarding the local variable hiding a field, post your entire code for us to come to conclusion.

First of all let me say one thing there is no such term as "Access specifier" in java. We should call everything as "Modifiers". As we know that final, static, synchronised, volatile.... are called as modifiers, even Public, private, protected, default, abstract should also be called as modifiers . Default is such a modifiers where physical existence is not there but no modifiers is placed then it should be treated as default modifiers.

To justify this take one example:

public class Simple{  
    public static void main(String args[]){  
     System.out.println("Hello Java");  
    }  
}  

Output will be: Hello Java

Now change public to private and see what compiler error you get: It says "Modifier private is not allowed here" What conclusion is someone can be wrong or some tutorial can be wrong but compiler cannot be wrong. So we can say there is no term access specifier in java everything is modifiers.

JAR files allow to package multiple files in order to use it as a library, plugin, or any kind of application. On the other hand, WAR files are used only for web applications.

JAR can be created with any desired structure. In contrast, WAR has a predefined structure with WEB-INF and META-INF directories.

A JAR file allows Java Runtime Environment (JRE) to deploy an entire application including the classes and the associated resources in a single request. On the other hand, a WAR file allows testing and deploying a web application easily.

Codecs proper:

ffmpeg -codecs

Formats:

ffmpeg -formats

In Ubuntu you can apply this way,

to save file at some location (temporary) and then open and send it to API

      path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
      path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
      data={} #can be anything u want to pass along with File
      file1 = open(path12, 'rb')
      header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
       res= requests.post(url,data,header)

The reason it prints "three" is because you didnt define your array. The equivalent to what you're doing is:

arr = []
for i in array :
    if i == "two" :
        arr.push(i)
print(i)

You are asking for the last element it looked through, which is not what you should be doing. You need to be storing the array to a variable in order to get the element.

The english equivalent of what you are doing is:

You: "I need you to print all the elements in this array that equal two, but in an array. And each time you cycle through the list, define the current element as I."
Computer: "Here: ["two"]"
You: "Now tell me 'i'"
Computer: "'i' is equal to "three"
You: "Why?"

The reason 'i' is equal to "three" is because three was the last thing that was defined as I

the computer did:

i = "one"
i = "two"
i = "three"

print(["two"])

Because you asked it to.

If you want the index, go here If you want the values in an array, define the array, like this:

MyArray = [(i) for i in my_list if i=="two"]

There's one more theoretical possibility to do it: professional versions of Windows have built-in POSIX support, so bash could have been compiled for Windows natively.

Pity, but I still haven't found a compiled one myself...

Use the setAttribute method:

document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");

But you really should be using data followed with a dash and with its property, like:

<li ... data-icon="base.gif" ...>

And to do it in JS use the dataset property:

document.getElementById('item1').dataset.icon = "base.gif";

This are the steps :

1. Download and install latest version of pclink for PC from here.
2. Make sure PCLink is running in Foreground on Asus Zenfone 5 and in settings on rightmost topmost corner click on USB icon and then check the MTP checkbox.
3. Click connect on PCLink on PC.
4. If Asus USB Driver for Zenfone 5 is properly installed on your PC.You will see 'Asus Android Device' in your Device Manager otherwise install Asus USB Driver for Zenfone 5 from here then try again
5. Now you will be able to see your device online in Android Studio and screen of your device on PCLink software on your PC.

I haven't tried for eclipse but it might work for that also.

This will allow numbers like 2/4 or numbers like 3.5 to be entered in your textbox if using decim "nonNumberEntered(e,Textbox1, True)".

Allows only numbers to be entered in textbox if using "nonNumberEntered(e,Textbox1, False)" or "nonNumberEntered(e,Textbox1)".

Edit: added text.

Why not just use the HR tag? It's made exactly for what you want. Kinda like trying to make a fork for eating soup when there's a spoon right in front of you on the table.

The current version (2019/03/07) is Build Tools for Visual Studio 2017. It's an online installer, you need to include at least the individual components:

• VC++ 2017 version xx.x tools
• Windows SDK to use standard libraries.

Here is another use case which worked well for me.

1. User tap a button/cell.
2. Scroll to a position just enough to make a target view visible.

Code: Swift 5.3

// Assuming you have a view named "targeView"
scrollView.scroll(to: CGPoint(x:targeView.frame.minX, y:targeView.frame.minY), animated: true)

As you can guess if you want to scroll to make a bottom part of your target view visible then use maxX and minY.

Try this little gem of a variation:

text-shadow:0 1px 1px rgba(255, 255, 255, 0.5);

I usually take "there's no answer" as a challenge

If you modify @hellslam's solution like this then it will work

I use this technique to drop the Database after my integration tests

//CoffeeScript
mongoose = require "mongoose"
conn = mongoose.connect("mongodb://localhost/mydb")

conn.connection.db.dropDatabase()

//JavaScript
var conn, mongoose;
mongoose = require("mongoose");
conn = mongoose.connect("mongodb://localhost/mydb");

conn.connection.db.dropDatabase();

HTH at least it did for me, so I decided to share =)

[A] If each of foo and bar is a single number, then there's nothing wrong with c(foo,bar); and you can also name the components: c(Foo=foo,Bar=bar). So you could access the components of the result 'res' as res[1], res[2]; or, in the named case, as res["Foo"], res["BAR"].

[B] If foo and bar are vectors of the same type and length, then again there's nothing wrong with returning cbind(foo,bar) or rbind(foo,bar); likewise nameable. In the 'cbind' case, you would access foo and bar as res[,1], res[,2] or as res[,"Foo"], res[,"Bar"]. You might also prefer to return a dataframe rather than a matrix:

data.frame(Foo=foo,Bar=bar)

and access them as res$Foo, res$Bar. This would also work well if foo and bar were of the same length but not of the same type (e.g. foo is a vector of numbers, bar a vector of character strings).

[C] If foo and bar are sufficiently different not to combine conveniently as above, then you shuld definitely return a list.

For example, your function might fit a linear model and also calculate predicted values, so you could have

LM<-lm(....) ; foo<-summary(LM); bar<-LM$fit

and then you would return list(Foo=foo,Bar=bar) and then access the summary as res$Foo, the predicted values as res$Bar

function inside a function or so called nested functions are very usable if you need to do some recursion processes such as looping true multiple layer of array or a file tree without multiple loops or sometimes i use it to avoid creating classes for small jobs which require dividing and isolating functionality among multiple functions. but before you go for nested functions you have to understand that

1. child function will not be available unless the main function is executed
2. Once main function got executed the child functions will be globally available to access
3. if you need to call the main function twice it will try to re define the child function and this will throw a fatal error

so is this mean you cant use nested functions? No, you can with the below workarounds

first method is to block the child function being re declaring into global function stack by using conditional block with function exists, this will prevent the function being declared multiple times into global function stack.

function myfunc($a,$b=5){
    if(!function_exists("child")){
        function child($x,$c){
            return $c+$x;   
        }
    }
    
    try{
        return child($a,$b);
    }catch(Exception $e){
        throw $e;
    }
    
}

//once you have invoke the main function you will be able to call the child function
echo myfunc(10,20)+child(10,10);

and the second method will be limiting the function scope of child to local instead of global, to do that you have to define the function as a Anonymous function and assign it to a local variable, then the function will only be available in local scope and will re declared and invokes every time you call the main function.

function myfunc($a,$b=5){
    $child = function ($x,$c){
        return $c+$x;   
    };
    
    try{
        return $child($a,$b);
    }catch(Exception $e){
        throw $e;
    }
    
}

echo myfunc(10,20);

remember the child will not be available outside the main function or global function stack

There's no isNumeric() type of function, but you could add your own:

function isNumeric(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

NOTE: Since parseInt() is not a proper way to check for numeric it should NOT be used.

ffill now has it's own method pd.DataFrame.ffill

df.ffill()

     0    1    2
0  1.0  2.0  3.0
1  4.0  2.0  3.0
2  4.0  2.0  9.0

Select convert(char(8), DATEADD(MINUTE, DATEDIFF(MINUTE, 0, getdate), 0), 108) as Time

will round down seconds to 00

Calling a REST API when using .NET 4.5 or .NET Core

I would suggest DalSoft.RestClient (caveat: I created it). The reason being, because it uses dynamic typing, you can wrap everything up in one fluent call including serialization/de-serialization. Below is a working PUT example:

dynamic client = new RestClient("http://jsonplaceholder.typicode.com");

var post = new Post { title = "foo", body = "bar", userId = 10 };

var result = await client.Posts(1).Put(post);

Java Language Specification says that

Program Exit

A program terminates all its activity and exits when one of two things happens:

All the threads that are not daemon threads terminate.

Some thread invokes the exit method of class Runtime or class System, and the exit operation is not forbidden by the security manager.

It means that You should use it when You have big program (well, at lest bigger than this one) and want to finish its execution.

Just wanted to add -- apparently this can also be caused by installing Instant Client for 10, then realizing you want the full install and installing it again in a parallel directory. I don't know why this broke it.

You have to insert the elements using the insert method present in vectors STL, check the below program to add the elements to it, and you can use in the same way in your program.

#include <iostream>
#include <vector>
#include <string.h>

int main ()
{
  std::vector<std::string> myvector ;
  std::vector<std::string>::iterator it;

   it = myvector.begin();
  std::string myarray [] = { "Hi","hello","wassup" };
  myvector.insert (myvector.begin(), myarray, myarray+3);

  std::cout << "myvector contains:";
  for (it=myvector.begin(); it<myvector.end(); it++)
    std::cout << ' ' << *it;
    std::cout << '\n';

  return 0;
}

For chart.js V2 (beta), use:

var options = {
    scales: {
        yAxes: [{
            display: true,
            ticks: {
                suggestedMin: 0,    // minimum will be 0, unless there is a lower value.
                // OR //
                beginAtZero: true   // minimum value will be 0.
            }
        }]
    }
};

See chart.js documentation on linear axes configuration for more details.

try: typeof(predQuery[preId])=='undefined'
or more generally: typeof(yourArray[yourIndex])=='undefined'
You're comparing "undefined" to undefined, which returns false =)

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

Why you are using row.Cells[row.Index]. You need to specify index of column you want to search (Problem #2). For example, you need to change row.Cells[row.Index] to row.Cells[2] where 2 is index of your column:

private void btnSearch_Click(object sender, EventArgs e)
{
    string searchValue = textBox1.Text;

    dgvProjects.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    try
    {
        foreach (DataGridViewRow row in dgvProjects.Rows)
        {
            if (row.Cells[2].Value.ToString().Equals(searchValue))
            {
                row.Selected = true;
                break;
            }
        }
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.Message);
    }
}

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

    @test
    testAbc() {
        myclass.setMyObj(myInterface); //it is good to have in @before method
        myClass.abc();
        verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
     }
}

The Actual solution of this problem is changing first line in web.php

Just replace Welcome route with following route

Route::view('/', 'welcome');

If still getting same error than you probab

I found that with curl 7.18.2 the download progress bar is not hidden with:

curl -s http://google.com > temp.html

but it is with:

curl -ss http://google.com > temp.html

Convert the argument to int. It's as simple as

int(argument)

This conversion is well defined and will yield the value UINT_MAX - 61. On a platform where unsigned int is a 32-bit type (most common platforms, these days), this is precisely the value that others are reporting. Other values are possible, however.

The actual language in the standard is

If the destination type is unsigned, the resulting value is the least unsigned integer congruent to the source integer (modulo 2^n where n is the number of bits used to represent the unsigned type).

When working collaboratively, or on multiple features at once, it's common that the upstream or even your master contains work that is not included in your branch, and will incorrectly appear in basic diffs.

If your Upstream may have moved, you should do this:

git fetch
git diff origin/master...

Just using git diff master can include, or fail to include, relevant changes.

For Mac users like me, there are several gotchas:

You cannot save to any directory you want. Only few of them can receive your saved files. More info there

Here is a working script that you can copy paste in your excel for Mac:

Public Sub SaveWorksheetsAsCsv()

 Dim WS As Excel.Worksheet
 Dim SaveToDirectory As String

 SaveToDirectory = "~/Library/Containers/com.microsoft.Excel/Data/"

 For Each WS In ThisWorkbook.Worksheet
    WS.SaveAs SaveToDirectory & WS.Name & ".csv", xlCSV
 Next

End Sub

After looking at some solutions, this worked for me.

I have one drop-down list with some values and I want to select the same value from another drop-down list... So first I put in a variable the selectIndex of my first drop-down.

var indiceDatos = $('#myidddl')[0].selectedIndex;

Then, I select that index on my second drop-down list.

$('#myidddl2')[0].selectedIndex = indiceDatos;

Note:

I guess this is the shortest, reliable, general and elegant solution.

Because in my case, I'm using selected option's data attribute instead of value attribute. So if you do not have unique value for each option, above method is the shortest and sweet!!

You can use the mask to copy only the region of interest of an original image to a destination one:

cvCopy(origImage,destImage,mask);

where mask should be an 8-bit single channel array.

See more at the OpenCV docs

You should look at the source of the HashSet constructor it calls... it's a special constructor that makes the backing Map a LinkedHashMap instead of just a HashMap.

try this : worked for me rm -rf .git

You can use mv instead of rm if you don't want to loose your stashed commits

then copy .git from other clone

cp <pathofotherrepository>/.git . -r

then do

git init

this should solve your problem , ALL THE BEST

Before sometime I also had the same problem. I have tried replacing the .dll file but no result. After some debugging I found the solution.

I had this in my php.ini file:

extension_dir = "ext"

And I'm getting mbstring extension missing error. So I tried putting the full path for the extension directory and it works for me. like:

extension_dir = "C:\php\ext"

Hope this will help.

Cheers,

In VB.NET there's a vbCrLf constant for linebreaks:

Dim s As String = "your string".Replace(vbCrLf, "")

change the opacity of the parent element with the border and this will re organize the stacked elements. This worked miraculously for me after hours of research and failed attempts. It was as simple as adding an opacity of 0.99 to re organize this paint process of browsers. Check out http://philipwalton.com/articles/what-no-one-told-you-about-z-index/

Yes. ArrayList has a toArray() method.

http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html

The problem with changing it via JavaScript or CSS is that if you have a slower connection, the image will take a second to change to the hovered version. This will cause an undesirable flash as one disappears while the other downloads.

What I've done before is have two images. Then hide and show each depending on the hover state. This will allow for a clean switch between the two images.

<a href="/settings">
    <img class="default" src="settings-default.svg"/>
    <img class="hover" src="settings-hover.svg"/>
    <span>Settings</span>
</a>

a img.hover {
    display: none;
}
a img.default {
    display: inherit;
}
a:hover img.hover {
    display: inherit;
}
a:hover img.default {
    display: none;
}

This is an IndexError in python, which means that we're trying to access an index which isn't there in the tensor. Below is a very simple example to understand this error.

# create an empty array of dimension `0`
In [14]: arr = np.array([], dtype=np.int64) 

# check its shape      
In [15]: arr.shape  
Out[15]: (0,)

with this array arr in place, if we now try to assign any value to some index, for example to the index 0 as in the case below

In [16]: arr[0] = 23     

Then, we will get an IndexError, as below:

---

IndexError                                Traceback (most recent call last)
<ipython-input-16-0891244a3c59> in <module>
----> 1 arr[0] = 23

IndexError: index 0 is out of bounds for axis 0 with size 0

The reason is that we are trying to access an index (here at 0^th position), which is not there (i.e. it doesn't exist because we have an array of size 0).

In [19]: arr.size * arr.itemsize  
Out[19]: 0

So, in essence, such an array is useless and cannot be used for storing anything. Thus, in your code, you've to follow the traceback and look for the place where you're creating an array/tensor of size 0 and fix that.

It's much more easier to add only the event for mousedown:

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        var hti = MyDataGridView.HitTest(e.X, e.Y);
        MyDataGridView.Rows[hti.RowIndex].Selected = true;
        MyDataGridView.Rows.RemoveAt(rowToDelete);
        MyDataGridView.ClearSelection();
    }
}

This is easier. Of cource you have to init your mousedown-event as already mentioned with:

this.MyDataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MyDataGridView_MouseDown);

in your constructor.

You guys are completely right numbers can only go in the numeric field. I use the exact same thing as already listed with a bit of css styling on a span tag:

<span>$</span><input type="number" min="0.01" step="0.01" max="2500" value="25.67">

Then add a bit of styling magic:

span{
  position:relative;
  margin-right:-20px
}
input[type='number']{
  padding-left:20px;
  text-align:left;
}

The reason they call it a stack is because each level derives off its base layer. Your operating system, Linux, is the base layer. Then Apache, your web daemon sits on top of your OS. Then your database stores all the information served by your web daemon, and PHP (or any P* scripting language) is used to drive and display all the data, and allow for user interaction.

Don't be overly concerned with the term 'stack'. People really just mean software suite or bundle, but you're using it just fine I am sure as you are.

Some googling led me to the following post:

http://www.developerweb.net/forum/showthread.php?t=3434

The code provided in the post is in C, but it shouldn't be too hard to rewrite it to Java.

This rule is intended to avoid conflicts in legacy code that still uses raw types.

Here's an illustration of why this was not allowed, drawn from the JLS. Suppose, before generics were introduced to Java, I wrote some code like this:

class CollectionConverter {
  List toList(Collection c) {...}
}

You extend my class, like this:

class Overrider extends CollectionConverter{
  List toList(Collection c) {...}
}

After the introduction of generics, I decided to update my library.

class CollectionConverter {
  <T> List<T> toList(Collection<T> c) {...}
}

You aren't ready to make any updates, so you leave your Overrider class alone. In order to correctly override the toList() method, the language designers decided that a raw type was "override-equivalent" to any generified type. This means that although your method signature is no longer formally equal to my superclass' signature, your method still overrides.

Now, time passes and you decide you are ready to update your class. But you screw up a little, and instead of editing the existing, raw toList() method, you add a new method like this:

class Overrider extends CollectionConverter {
  @Override
  List toList(Collection c) {...}
  @Override
  <T> List<T> toList(Collection<T> c) {...}
}

Because of the override equivalence of raw types, both methods are in a valid form to override the toList(Collection<T>) method. But of course, the compiler needs to resolve a single method. To eliminate this ambiguity, classes are not allowed to have multiple methods that are override-equivalent—that is, multiple methods with the same parameter types after erasure.

The key is that this is a language rule designed to maintain compatibility with old code using raw types. It is not a limitation required by the erasure of type parameters; because method resolution occurs at compile-time, adding generic types to the method identifier would have been sufficient.

1. Go to server View
2. Double click the server for which you want to change the time limit
3. On the right hand side you have timeouts dropdown tab. Select that.
4. You then have option to change the time limits.

I just had to do this myself, so I thought I would post another answer here.

Here is another way to create a rounded corner border and clip its inner content. This is the straightforward way by using the Clip property. It's nice if you want to avoid a VisualBrush.

The xaml:

<Border
    Width="200"
    Height="25"
    CornerRadius="11"
    Background="#FF919194"
>
    <Border.Clip>
        <RectangleGeometry
            RadiusX="{Binding CornerRadius.TopLeft, RelativeSource={RelativeSource AncestorType={x:Type Border}}}"
            RadiusY="{Binding RadiusX, RelativeSource={RelativeSource Self}}"
        >
            <RectangleGeometry.Rect>
                <MultiBinding
                    Converter="{StaticResource widthAndHeightToRectConverter}"
                >
                    <Binding
                        Path="ActualWidth"
                        RelativeSource="{RelativeSource AncestorType={x:Type Border}}"
                    />
                    <Binding
                        Path="ActualHeight"
                        RelativeSource="{RelativeSource AncestorType={x:Type Border}}"
                    />
                </MultiBinding>
            </RectangleGeometry.Rect>
        </RectangleGeometry>
    </Border.Clip>

    <Rectangle
        Width="100"
        Height="100"
        Fill="Blue"
        HorizontalAlignment="Left"
        VerticalAlignment="Center"
    />
</Border>

The code for the converter:

public class WidthAndHeightToRectConverter : IMultiValueConverter
{
    public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
    {
        double width = (double)values[0];
        double height = (double)values[1];
        return new Rect(0, 0, width, height);
    }
    public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

This will load a file in working directory:

        static void Main(string[] args)
        {
            string fileName = System.IO.Path.GetFullPath(Directory.GetCurrentDirectory() + @"\Yourfile.txt");

            Console.WriteLine("Your file content is:");
            using (StreamReader sr = File.OpenText(fileName))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
            }

            Console.ReadKey();
        }

If your using console you can also do this.It will prompt the user to write the path of the file(including filename with extension).

        static void Main(string[] args)
        {

            Console.WriteLine("****please enter path to your file****");
            Console.Write("Path: ");
            string pth = Console.ReadLine();
            Console.WriteLine();
            Console.WriteLine("Your file content is:");
            using (StreamReader sr = File.OpenText(pth))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
            }

            Console.ReadKey();
        }

If you use winforms for example try this simple example:

        private void button1_Click(object sender, EventArgs e)
        {
            string pth = "";
            OpenFileDialog ofd = new OpenFileDialog();

            if (ofd.ShowDialog() == DialogResult.OK)
            {
                pth = ofd.FileName;
                textBox1.Text = File.ReadAllText(pth);
            }
        }

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

You can go for identifying a list of elements with xPath:

//td[text() = ' Color Digest ']/following-sibling::td[1]

This will give you a list of two elements, than you can use the 2nd element as your intended one. For example:

List<WebElement> elements = driver.findElements(By.xpath("//td[text() = ' Color Digest ']/following-sibling::td[1]"))

Now, you can use the 2nd element as your intended element, which is elements.get(1)

Use wp_localize_script and pass url there:

wp_localize_script( some_handle, 'admin_url', array('ajax_url' => admin_url( 'admin-ajax.php' ) ) );

then inside js, you can call it by

admin_url.ajax_url 

Cross browser solution for printing pdf from base64 string:

• Chrome: print window is opened
• FF: new tab with pdf is opened
• IE11: open/save prompt is opened

.

const blobPdfFromBase64String = base64String => {
   const byteArray = Uint8Array.from(
     atob(base64String)
       .split('')
       .map(char => char.charCodeAt(0))
   );
  return new Blob([byteArray], { type: 'application/pdf' });
};

const isIE11 = !!(window.navigator && window.navigator.msSaveOrOpenBlob); // or however you want to check it

const printPDF = blob => {
   try {
     isIE11
       ? window.navigator.msSaveOrOpenBlob(blob, 'documents.pdf')
       : printJS(URL.createObjectURL(blob)); // http://printjs.crabbly.com/
   } catch (e) {
     throw PDFError;
   }
};

printPDF(blobPdfFromBase64String(base64String))

BONUS - Opening blob file in new tab for IE11

If you're able to do some preprocessing of the base64 string on the server you could expose it under some url and use the link in printJS :)

I deal with this question at work often:

• FTP feeds of inventory and pricing - Item descriptions and other text were in nvarchar when varchar worked fine. Converting these to varchar reduced file size almost in half and really helped with uploads.

• The above scenario worked fine until someone put a special character in the item description (maybe trademark, can't remember)

I still do not use nvarchar every time over varchar. If there is any doubt or potential for special characters, I use nvarchar. I find I use varchar mostly when I am in 100% control of what is populating the field.

For me following code work

$(function () {
    debugger;
    document.getElementById("FormId").addEventListener("submit", function (e) {
        debugger;
        if (ValidDateFrom()) { // Check Validation 
            var form = e.target;
            if (form.getAttribute("enctype") === "multipart/form-data") {
                debugger;
                if (form.dataset.ajax) {
                    e.preventDefault();
                    e.stopImmediatePropagation();
                    var xhr = new XMLHttpRequest();
                    xhr.open(form.method, form.action);
                    xhr.onreadystatechange = function (result) {
                        debugger;
                        if (xhr.readyState == 4 && xhr.status == 200) {
                            debugger;
                            var responseData = JSON.parse(xhr.responseText);
                            SuccessMethod(responseData); // Redirect to your Success method 
                        }
                    };
                    xhr.send(new FormData(form));
                }
            }
        }
    }, true);
});

In your Action Post Method, pass parameter as HttpPostedFileBase UploadFile and make sure your file input has same as mentioned in your parameter of the Action Method. It should work with AJAX Begin form as well.

Remember over here that your AJAX BEGIN Form will not work over here since you make your post call defined in the code mentioned above and you can reference your method in the code as per the Requirement

I know I am answering late but this is what worked for me

The windows handle limit for your application is 10,000 handles. You're getting the error because your program is creating too many handles. You'll need to find the memory leak. As other users have suggested, use a Memory Profiler. I use the .Net Memory Profiler as well. Also, make sure you're calling the dispose method on controls if you're removing them from a form before the form closes (otherwise the controls won't dispose). You'll also have to make sure that there are no events registered with the control. I myself have the same issue, and despite what I already know, I still have some memory leaks that continue to elude me..

In View

<select ng-model="boxmodel"><option ng-repeat="lst in list" value="{{lst.id}}">{{lst.name}}</option></select>

JS:

In side controller

 $scope.boxModel = 600;

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

Current thinking seems to be to "tolerate" nulls, that is, to allow them in general, although some operations are less tolerant and may end up throwing NPE. See the discussion of nulls on the Lambda Libraries expert group mailing list, specifically this message. Consensus around option #3 subsequently emerged (with a notable objection from Doug Lea). So yes, the OP's concern about pipelines blowing up with NPE is valid.

It's not for nothing that Tony Hoare referred to nulls as the "Billion Dollar Mistake." Dealing with nulls is a real pain. Even with classic collections (without considering lambdas or streams) nulls are problematic. As fge mentioned in a comment, some collections allow nulls and others do not. With collections that allow nulls, this introduces ambiguities into the API. For example, with Map.get(), a null return indicates either that the key is present and its value is null, or that the key is absent. One has to do extra work to disambiguate these cases.

The usual use for null is to denote the absence of a value. The approach for dealing with this proposed for Java SE 8 is to introduce a new java.util.Optional type, which encapsulates the presence/absence of a value, along with behaviors of supplying a default value, or throwing an exception, or calling a function, etc. if the value is absent. Optional is used only by new APIs, though, everything else in the system still has to put up with the possibility of nulls.

My advice is to avoid actual null references to the greatest extent possible. It's hard to see from the example given how there could be a "null" Otter. But if one were necessary, the OP's suggestions of filtering out null values, or mapping them to a sentinel object (the Null Object Pattern) are fine approaches.

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

varargs could do that (in a way). Other than that, all variables in the declaration of the method must be supplied. If you want a variable to be optional, you can overload the method using a signature which doesn't require the parameter.

private boolean defaultOptionalFlagValue = true;

public void doSomething(boolean optionalFlag) {
    ...
}

public void doSomething() {
    doSomething(defaultOptionalFlagValue);
}

You can also use events to trigger the Popdown.

Here's a fiddle based on satchmorun's solution. It dispenses with the PopdownAPI, and the top-level controller instead $broadcasts 'success' and 'error' events down the scope chain:

$scope.success = function(msg) { $scope.$broadcast('success', msg); };
$scope.error   = function(msg) { $scope.$broadcast('error', msg); };

The Popdown module then registers handler functions for these events, e.g:

$scope.$on('success', function(event, msg) {
    $scope.status = 'success';
    $scope.message = msg;
    $scope.toggleDisplay();
});

This works, at least, and seems to me to be a nicely decoupled solution. I'll let others chime in if this is considered poor practice for some reason.

item=sp.getItemAtPosition(i).toString();
list.add(item);
adapter.notifyDataSetChanged () ;

look up ArrayAdapter.notifyDataSetChanged()

For complete M B answer, if you want to access to an specific attribute of this object already filtered from the array in your HTML, you will have to do it in this way:

{{ (myArray | filter : {'id':73})[0].name }}

So, in this case, it will print john in the HTML.

Regards!

This's a jQuery free solution that can work with SPA inside the iframe

document.getElementById('iframe-id').addEventListener('load', function () {
  let that = this;
  setTimeout(function () {
    that.style.height = that.contentWindow.document.body.offsetHeight + 'px';
  }, 2000) // if you're having SPA framework (angularjs for example) inside the iframe, some delay is needed for the content to populate
});

var $iframe = document.getElementByID('myIfreme');
var childDocument = iframe.contentDocument ? iframe.contentDocument : iframe.contentWindow.document;
 childDocument.documentElement.scrollTop = 0;

I had to restart the rails application on the production so I looked for an another answer. I have found it below:

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

One might consider adding this line to ~/.bash_profile (or similar) in order to can quickly get the current UTC both as current time and as seconds since the epoch.

alias utc='date -u && date -u +%s'

Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.

Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

After sorting out your php scripts, don't forget to tell mysql what charset you are passing and would like to recceive.

Example: set character set utf8

Passing utf8 data to a latin1 table in a latin1 I/O session gives those nasty birdfeets. I see this every other day in oscommerce shops. Back and fourth it might seem right. But phpmyadmin will show the truth. By telling mysql what charset you are passing it will handle the conversion of mysql data for you.

How to recover existing scrambled mysql data is another thread to discuss. :)

<input id="inputFileToLoad" type="file" onchange="encodeImageFileAsURL();" />

    if (filesSelected.length > 0) {
      var fileToLoad = filesSelected[0];

      var fileReader = new FileReader();

      fileReader.onload = function(fileLoadedEvent) {
        var srcData = fileLoadedEvent.target.result; // <--- data: base64

        var newImage = document.createElement('img');
        newImage.src = srcData;

        document.getElementById("imgTest").innerHTML = newImage.outerHTML;
        alert("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);
        console.log("Converted Base64 version is " + document.getElementById("imgTest").innerHTML);

    }

Since Java 8, there are lambda and method references:

• Oracle Docs: Lambda Expressions
• Oracle Docs: Method References

For example, if you want a functional interface A -> B such as:

import java.util.function.Function;

public MyClass {
    public static String applyFunction(String name, Function<String,String> function){
        return function.apply(name);
    }
}

then you can call it like so

MyClass.applyFunction("42", str -> "the answer is: " + str);
// returns "the answer is: 42"

Also you can pass class method. Say you have:

@Value // lombok
public class PrefixAppender {
    private String prefix;

    public String addPrefix(String suffix){
        return prefix +":"+suffix;
    }
}

Then you can do:

PrefixAppender prefixAppender= new PrefixAppender("prefix");
MyClass.applyFunction("some text", prefixAppender::addPrefix);
// returns "prefix:some text"

Note:

Here I used the functional interface Function<A,B>, but there are many others in the package java.util.function. Most notable ones are

• Supplier: void -> A
• Consumer: A -> void
• BiConsumer: (A,B) -> void
• Function: A -> B
• BiFunction: (A,B) -> C

and many others that specialize on some of the input/output type. Then, if it doesn't provide the one you need, you can create your own functional interface like so:

@FunctionalInterface
interface Function3<In1, In2, In3, Out> { // (In1,In2,In3) -> Out
    public Out apply(In1 in1, In2 in2, In3 in3);
}

Example of use:

String computeAnswer(Function3<String, Integer, Integer, String> f){
    return f.apply("6x9=", 6, 9);
}

computeAnswer((question, a, b) -> question + "42");
// "6*9=42"

And you can also do that with thrown exception:

@FunctionalInterface
interface FallibleFunction<In, Out, Ex extends Exception> {
    Out get(In input) throws Ex;
}
public <Ex extends IOException> String yo(FallibleFunction<Integer, String, Ex> f) throws Ex {
    return f.get(42);
}

IF you want to derive usg Boolean true False need to add "[]" around value

<form [formGroup]="form">
  <input type="radio" [value]=true formControlName="gender" >Male
  <input type="radio" [value]=false formControlName="gender">Female
</form>

Look into the MemoryStream class.

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.

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

I think this represents a good answer.

APK Signature Scheme v2 verification

1. Locate the APK Signing Block and verify that:
   1. Two size fields of APK Signing Block contain the same value.
   2. ZIP Central Directory is immediately followed by ZIP End of Central Directory record.
   3. ZIP End of Central Directory is not followed by more data.
2. Locate the first APK Signature Scheme v2 Block inside the APK Signing Block. If the v2 Block if present, proceed to step 3. Otherwise, fall back to verifying the APK using v1 scheme.
3. For each signer in the APK Signature Scheme v2 Block:
   1. Choose the strongest supported signature algorithm ID from signatures. The strength ordering is up to each implementation/platform version.
   2. Verify the corresponding signature from signatures against signed data using public key. (It is now safe to parse signed data.)
   3. Verify that the ordered list of signature algorithm IDs in digests and signatures is identical. (This is to prevent signature stripping/addition.)
   4. Compute the digest of APK contents using the same digest algorithm as the digest algorithm used by the signature algorithm.
   5. Verify that the computed digest is identical to the corresponding digest from digests.
   6. Verify that SubjectPublicKeyInfo of the first certificate of certificates is identical to public key.
4. Verification succeeds if at least one signer was found and step 3 succeeded for each found signer.

Note: APK must not be verified using the v1 scheme if a failure occurs in step 3 or 4.

JAR-signed APK verification (v1 scheme)

The JAR-signed APK is a standard signed JAR, which must contain exactly the entries listed in META-INF/MANIFEST.MF and where all entries must be signed by the same set of signers. Its integrity is verified as follows:

1. Each signer is represented by a META-INF/<signer>.SF and META-INF/<signer>.(RSA|DSA|EC) JAR entry.
2. <signer>.(RSA|DSA|EC) is a PKCS #7 CMS ContentInfo with SignedData structure whose signature is verified over the <signer>.SF file.
3. <signer>.SF file contains a whole-file digest of the META-INF/MANIFEST.MF and digests of each section of META-INF/MANIFEST.MF. The whole-file digest of the MANIFEST.MF is verified. If that fails, the digest of each MANIFEST.MF section is verified instead.
4. META-INF/MANIFEST.MF contains, for each integrity-protected JAR entry, a correspondingly named section containing the digest of the entry’s uncompressed contents. All these digests are verified.
5. APK verification fails if the APK contains JAR entries which are not listed in the MANIFEST.MF and are not part of JAR signature. The protection chain is thus <signer>.(RSA|DSA|EC) ? <signer>.SF ? MANIFEST.MF ? contents of each integrity-protected JAR entry.

This is the fastest and the most readable way:

this.setState({...this.state.jasper, name: 'someothername'});

Even if this.state.jasper already contains a name property, the new name name: 'someothername' with be used.

@Pratik Sharma

For support negative numbers, add the following code within the filter method:

package ir.aboy.electronicarsenal;

import android.text.InputFilter;
import android.text.Spanned;

public class InputFilterMinMax implements InputFilter {

  private int min, max;
  int input;

  InputFilterMinMax(int min, int max) {
    this.min = min;
    this.max = max;
  }

  public InputFilterMinMax(String min, String max) {
    this.min = Integer.parseInt(min);
    this.max = Integer.parseInt(max);
  }

  @Override
  public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    try {

      if ((dest.toString() + source.toString()).equals("-")) {
        source = "-1";
      }

      input = Integer.parseInt(dest.toString() + source.toString());
      if (isInRange(min, max, input))
        return null;

    } catch (NumberFormatException ignored) {
    }
    return "";
  }

  private boolean isInRange(int a, int b, int c) {
    return b > a ? c >= a && c <= b : c >= b && c <= a;
  }

}

Then use this from your Activity :

findViewById(R.id.myEditText).setFilters(new InputFilter[]{ new InputFilterMinMax(1, 12)});

Set your edittext with:

android:inputType="number|numberSigned"

We could simply write the following method

public static void ClearLine()
{
    Console.SetCursorPosition(0, Console.CursorTop - 1);
    Console.Write(new string(' ', Console.WindowWidth));
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}

and then call it when needed like this

Console.WriteLine("Test");
ClearLine();

It works fine for me.

In here you can save the phone number as international formatted phone number

internationalFormatPhoneNumber = phoneUtil.format(givenPhoneNumber, PhoneNumberFormat.INTERNATIONAL);

it return the phone number as International format +94 71 560 4888

so now I have get country code as this

String countryCode = internationalFormatPhoneNumber.substring(0,internationalFormatPhoneNumber.indexOf('')).replace('+', ' ').trim();

Hope this will help you

Extending the Quote idea for Objective-C:

#define NSStringMultiline(...) [[NSString alloc] initWithCString:#__VA_ARGS__ encoding:NSUTF8StringEncoding]

NSString *sql = NSStringMultiline(
    SELECT name, age
    FROM users
    WHERE loggedin = true
);

By the way, instead of generating the x and y coordinates yourself, you can also use the curve() function, which is intended to draw curves corresponding to a function (such as the density of a standard normal function).

see

help(curve)

and its examples.

And if you want to add som text to properly label the mean and standard deviations, you can use the text() function (see also plotmath, for annotations with mathematical symbols) .

Disclaimer: As of early 2015, there is a great comparison of IoC Container features from Jimmy Bogard, here is a summary:

Compared Containers:

• Autofac
• Ninject
• Simple Injector
• StructureMap
• Unity
• Windsor

The scenario is this: I have an interface, IMediator, in which I can send a single request/response or a notification to multiple recipients:

public interface IMediator 
{ 
    TResponse Send<TResponse>(IRequest<TResponse> request);

    Task<TResponse> SendAsync<TResponse>(IAsyncRequest<TResponse> request);

    void Publish<TNotification>(TNotification notification)
        where TNotification : INotification;

    Task PublishAsync<TNotification>(TNotification notification)
        where TNotification : IAsyncNotification; 
}

I then created a base set of requests/responses/notifications:

public class Ping : IRequest<Pong>
{
    public string Message { get; set; }
}
public class Pong
{
    public string Message { get; set; }
}
public class PingAsync : IAsyncRequest<Pong>
{
    public string Message { get; set; }
}
public class Pinged : INotification { }
public class PingedAsync : IAsyncNotification { }

I was interested in looking at a few things with regards to container support for generics:

• Setup for open generics (registering IRequestHandler<,> easily)
• Setup for multiple registrations of open generics (two or more INotificationHandlers)

Setup for generic variance (registering handlers for base INotification/creating request pipelines) My handlers are pretty straightforward, they just output to console:

public class PingHandler : IRequestHandler<Ping, Pong> { /* Impl */ }
public class PingAsyncHandler : IAsyncRequestHandler<PingAsync, Pong> { /* Impl */ }

public class PingedHandler : INotificationHandler<Pinged> { /* Impl */ }
public class PingedAlsoHandler : INotificationHandler<Pinged> { /* Impl */ }
public class GenericHandler : INotificationHandler<INotification> { /* Impl */ }

public class PingedAsyncHandler : IAsyncNotificationHandler<PingedAsync> { /* Impl */ }
public class PingedAlsoAsyncHandler : IAsyncNotificationHandler<PingedAsync> { /* Impl */ }

each socket joins a room with a socket id for a name, so you can just

ICollection<T> is used because the IEnumerable<T> interface provides no way of adding items, removing items, or otherwise modifying the collection.

If you have SSH access, you don't need to SSH first and then copy, just use Secure Copy (SCP) from the destination.

scp user@host:/path/file /localpath/file

Wild card characters are supported, so

scp user@host:/path/folder/* /localpath/folder

will copy all of the remote files in that folder.If copying more then one directory.

note -r will copy all sub-folders and content too.

React recommends bind this in all methods that needs to use this of class instead this of self function.

constructor(props) {
    super(props)
    this.onClick = this.onClick.bind(this)
}

 onClick () {
     this.setState({...})
 }

Or you may to use arrow function instead.

For Python 3:

>>> exec(open("helloworld.py").read())

Make sure that you're in the correct directory before running the command.

To run a file from a different directory, you can use the below command:

with open ("C:\\Users\\UserName\\SomeFolder\\helloworld.py", "r") as file:
    exec(file.read())

For selections, you can also convert the selection using the "To spaces" function. I usually just use it via the ctrl-shift-A then find "To Spaces" from there.

To write a newline use \n not /n the latter is just a slash and a n

Thanks to @nekno and @ale84 for great answers.

However, I modified @ale84's script it little to increment build numbers for floating point.

the value of incl can be changed according to your floating format requirements. For eg: if incl = .01, output format would be ... 1.19, 1.20, 1.21 ...

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
incl=.01
buildNumber=`echo $buildNumber + $incl|bc`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

This is the class where the connection is established and messages are recieved. Make sure to pair the devices before you run the application. If you want to have a slave/master connection, where each slave can only send messages to the master , and the master can broadcast messages to all slaves. You should only pair the master with each slave , but you shouldn't pair the slaves together.

Your main activity should be as follow :

package com.example.gaby.coordinatorv1;

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

public class MainActivity extends Activity {

    private Button discoveryButton;
    private Button messageButton;

    private Piconet piconet;

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

        piconet = new Piconet(getApplicationContext());

        messageButton = (Button) findViewById(R.id.messageButton);
        messageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                piconet.bluetoothBroadcastMessage("Hello World---*Gaby Bou Tayeh*");
            }
        });

        discoveryButton = (Button) findViewById(R.id.discoveryButton);
        discoveryButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                piconet.startPiconet();
            }
        });

    }

}

And here's the XML Layout :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Button
    android:id="@+id/discoveryButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Discover"
    />

<Button
    android:id="@+id/messageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Send message"
    />

Do not forget to add the following permissions to your Manifest File :

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

name = ( (city.getName() == null)? "N/A" : city.getName() );

firstly the condition (city.getName() == null) is checked. If yes, then "N/A" is assigned to name or simply name="N/A" or else the value from city.getName() is assigned to name, i.e. name=city.getName().

Things to look out here:

1. condition is in the parenthesis followed by a question mark. That's why I write (city.getName() == null)?. Here the question mark is right after the condition. Easy to see/read/guess even!
2. value left of colon (:) and value right of colon (a) value left of colon is assigned when condition is true, else the value right of colon is assigned to the variable.

here's a reference: http://www.cafeaulait.org/course/week2/43.html

rem set defaults:
set filename1="c:\file1.txt"
set filename2="c:\file2.txt"
set filename3="c:\file3.txt"
rem set parameters:
IF NOT "a%1"=="a" (set filename1="%1")
IF NOT "a%2"=="a" (set filename2="%2")
IF NOT "a%3"=="a" (set filename1="%3")
echo %filename1%, %filename2%, %filename3%

Be careful with quotation characters though, you may or may not need them in your variables.

Instead of gdb, run gdbtui. Or run gdb with the -tui switch. Or press C-x C-a after entering gdb. Now you're in GDB's TUI mode.

Enter layout asm to make the upper window display assembly -- this will automatically follow your instruction pointer, although you can also change frames or scroll around while debugging. Press C-x s to enter SingleKey mode, where run continue up down finish etc. are abbreviated to a single key, allowing you to walk through your program very quickly.

I think the docs explain the difference and usage of these two functions pretty well:

newFixedThreadPool

Creates a thread pool that reuses a fixed number of threads operating off a shared unbounded queue. At any point, at most nThreads threads will be active processing tasks. If additional tasks are submitted when all threads are active, they will wait in the queue until a thread is available. If any thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks. The threads in the pool will exist until it is explicitly shutdown.

newCachedThreadPool

Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available. These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks. Calls to execute will reuse previously constructed threads if available. If no existing thread is available, a new thread will be created and added to the pool. Threads that have not been used for sixty seconds are terminated and removed from the cache. Thus, a pool that remains idle for long enough will not consume any resources. Note that pools with similar properties but different details (for example, timeout parameters) may be created using ThreadPoolExecutor constructors.

In terms of resources, the newFixedThreadPool will keep all the threads running until they are explicitly terminated. In the newCachedThreadPool Threads that have not been used for sixty seconds are terminated and removed from the cache.

Given this, the resource consumption will depend very much in the situation. For instance, If you have a huge number of long running tasks I would suggest the FixedThreadPool. As for the CachedThreadPool, the docs say that "These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks".

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

    String tempVal = null;
    for (int i = 0; i < l.size(); i++) {
        tempVal = l.get(i); //take the ith object out of list
        while (l.contains(tempVal)) {
            l.remove(tempVal); //remove all matching entries
        }
        l.add(tempVal); //at last add one entry
    }

Note: this will have major performance hit though as items are removed from start of the list. To address this, we have two options. 1) iterate in reverse order and remove elements. 2) Use LinkedList instead of ArrayList. Due to biased questions asked in interviews to remove duplicates from List without using any other collection, above example is the answer. In real world though, if I have to achieve this, I will put elements from List to Set, simple!

find is just made for that.

find /tmp -name '*.pdf' -or -name '*.doc' | xargs rm

Your item variable holds Array instance (in [hash_key, hash_value] format), so it doesn't expect Symbol in [] method.

This is how you could do it using Hash#each:

def format(hash)
  output = Hash.new
  hash.each do |key, value|
    output[key] = cleanup(value)
  end
  output
end

or, without this:

def format(hash)
  output = hash.dup
  output[:company_name] = cleanup(output[:company_name])
  output[:street] = cleanup(output[:street])
  output
end

If you are using the XmlDocument and XmlNode.

Say:

XmlNode f = root.SelectSingleNode("//form[@id='myform']");

Use:

XmlNode s = f.SelectSingleNode(".//input[@type='submit']");

It depends on the tool that you use. But .// will select any child, any depth from a reference node.

SELECT  * 
FROM 
        (
            SELECT * FROM TABLE_A 
            UNION ALL 
            SELECT * FROM TABLE_B
        ) dum
-- ORDER BY .....

but if you want to have all records from Table_A on the top of the result list, the you can add user define value which you can use for ordering,

SELECT  * 
FROM 
        (
            SELECT *, 1 sortby FROM TABLE_A 
            UNION ALL 
            SELECT *, 2 sortby FROM TABLE_B
        ) dum
ORDER   BY sortby

I have read or heard that Mac OS X is written mostly in Objective-C with some of the lower level parts, such as the kernel, and hardware device drivers written in C. I believe that Apple "eat(s) its own dog food", meaning that they write Mac OS X using their own Xcode Developer Tools. The GCC(GNU Compiler Collection) compiler-linker is the unix command line tool that xCode used for most of its compiling and/or linking of executables. Among other possible languages, I know GCC compiles source code from the C, Objective-C, C++ and Objective-C++ languages.

Add this single line in manifest (for permission)

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

Then paste this code in your activity

private ArrayList<String> getPrimaryMailId() {
    ArrayList<String> accountsList = new ArrayList<String>();
    try {
        Account[] accounts = AccountManager.get(this).getAccountsByType("com.google");
        for (Account account : accounts) {
            accountsList.add(account.name);
            Log.e("GetPrimaryMailId ", account.name);
        }
    } catch (Exception e) {
        Log.e("GetPrimaryMailId", " Exception : " + e);
    }
    return accountsList;
}

This is what I expected to see when I came to this question:

import pandas as pd


df = pd.DataFrame([(1, 2, 3, 4),
                   (5, 6, 7, 8),
                   (9, 0, 1, 2),
                   (3, 4, 5, 6)],
                  columns=list('abcd'),
                  index=['India', 'France', 'England', 'Germany'])
print(df)

gives

France   5  6  7  8
England  9  0  1  2

you can use System.Diagnostics.Process.Start as well as WIN32 ShellExecute function by means of interop, for opening PDF files using the default viewer:

System.Diagnostics.Process.Start("SOMEAPP.EXE","Path/SomeFile.Ext");

[System.Runtime.InteropServices.DllImport("shell32. dll")]
private static extern long ShellExecute(Int32 hWnd, string lpOperation, 
                                    string lpFile, string lpParameters, 
                                        string lpDirectory, long nShowCmd);

Another approach is to place a WebBrowser Control into your Form and then use the Navigate method for opening the PDF file:

ThewebBrowserControl.Navigate(@"c:\the_file.pdf");

//: Playground - noun: a place where people can play

import UIKit

class A {
    class func a() {
        print("yeah")
    }

    func getInnerValue() {
        self.dynamicType.a()
    }
}

class B: A {
    override class func a() {
        print("yeah yeah")
    }
}

B.a() // yeah yeah
A.a() // yeah
B().getInnerValue() // yeah yeah
A().getInnerValue() // yeah

a bit late, but it might be worth checking the "indicator" parameter of pd.merge.

Performance: as Jeffrey said in his reply, in Java it doesn't make much difference.

Generally, for readability of the code, your choice of where to catch the exception depends upon whether you want the loop to keep processing or not.

In your example you returned upon catching an exception. In that case, I'd put the try/catch around the loop. If you simply want to catch a bad value but carry on processing, put it inside.

The third way: You could always write your own static ParseFloat method and have the exception handling dealt with in that method rather than your loop. Making the exception handling isolated to the loop itself!

class Parsing
{
    public static Float MyParseFloat(string inputValue)
    {
        try
        {
            return Float.parseFloat(inputValue);
        }
        catch ( NumberFormatException e )
        {
            return null;
        }
    }

    // ....  your code
    for(int i = 0; i < max; i++) 
    {
        String myString = ...;
        Float myNum = Parsing.MyParseFloat(myString);
        if ( myNum == null ) return;
        myFloats[i] = (float) myNum;
    }
}

You can use CAST() to convert from string to int. e.g. SELECT CAST('123' AS INTEGER);

I just utilize Network Interface Names, my custom command is

[[ $(ip addr | grep enp0s25) != '' ]] && ip addr show dev enp0s25 | sed -n -r 's@.*inet (.*)/.*brd.*@\1@p' || ip addr show dev eth0 | sed -n -r 's@.*inet (.*)/.*brd.*@\1@p' 

in my own notebook

[flying@lempstacker ~]$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 
[flying@lempstacker ~]$ [[ $(ip addr | grep enp0s25) != '' ]] && ip addr show dev enp0s25 | sed -n -r 's@.*inet (.*)/.*brd.*@\1@p' || ip addr show dev eth0 | sed -n -r 's@.*inet (.*)/.*brd.*@\1@p'
192.168.2.221

but if the network interface owns at least one ip, then it will show all ip belong to it

Swift 3, with extension:

extension UIView{
    var globalPoint :CGPoint? {
        return self.superview?.convert(self.frame.origin, to: nil)
    }

    var globalFrame :CGRect? {
        return self.superview?.convert(self.frame, to: nil)
    }
}

move does not make sense for a hashmap since its a dictionary with a hashcode for bucketing based on key and then a linked list for colliding hashcodes resolved via equals. Use a TreeMap for sorted maps and then pass in a custom comparator.

Swift 3:

private func validate(phoneNumber: String) -> Bool {
    let charcterSet  = NSCharacterSet(charactersIn: "+0123456789").inverted
    let inputString = phoneNumber.components(separatedBy: charcterSet)
    let filtered = inputString.joined(separator: "")
    return  phoneNumber == filtered
}

bash handles only integer maths but you can use bc command as follows:

$ num1=3.17648E-22
$ num2=1.5
$ echo $num1'>'$num2 | bc -l
0
$ echo $num2'>'$num1 | bc -l
1

Note that exponent sign must be uppercase

In this case, you may want to check if element exists in current DOM

if you want to check if element exist in DOM tree (is attached to DOM), you can use:

var data = $('#data_1'); 
if(jQuery.contains(document.documentElement, data[0])){
    // #data_1 element attached to DOM
} else {
    // is not attached to DOM
}

select Id, StartDate,
Case IsNull (StartDate , '01/01/1800')
When '01/01/1800' then
  'Awaiting'
Else
  'Approved'
END AS StartDateStatus
From MyTable

A "name" (Net, Host, Gateway, or Domain name) is a text string up to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus sign (-), and period (.). Note that periods are only allowed when they serve to delimit components of "domain style names". (See RFC-921, "Domain Name System Implementation Schedule", for background). No blank or space characters are permitted as part of a name. No distinction is made between upper and lower case. The first character must be an alpha character. The last character must not be a minus sign or period. A host which serves as a GATEWAY should have "-GATEWAY" or "-GW" as part of its name. Hosts which do not serve as Internet gateways should not use "-GATEWAY" and "-GW" as part of their names. A host which is a TAC should have "-TAC" as the last part of its host name, if it is a DoD host. Single character names or nicknames are not allowed.

I got this error generating a data frame consisting of timestamps and data:

df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp))

Adding the suggested solution works for me:

df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp), dtype=float))

Visual Studio's UserVoice gives a link to generic OrderedDictionary implementation by dotmore.

But if you only need to get key/value pairs by index and don't need to get values by keys, you may use one simple trick. Declare some generic class (I called it ListArray) as follows:

class ListArray<T> : List<T[]> { }

You may also declare it with constructors:

class ListArray<T> : List<T[]>
{
    public ListArray() : base() { }
    public ListArray(int capacity) : base(capacity) { }
}

For example, you read some key/value pairs from a file and just want to store them in the order they were read so to get them later by index:

ListArray<string> settingsRead = new ListArray<string>();
using (var sr = new StreamReader(myFile))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {
        string[] keyValueStrings = line.Split(separator);
        for (int i = 0; i < keyValueStrings.Length; i++)
            keyValueStrings[i] = keyValueStrings[i].Trim();
        settingsRead.Add(keyValueStrings);
    }
}
// Later you get your key/value strings simply by index
string[] myKeyValueStrings = settingsRead[index];

As you may have noticed, you can have not necessarily just pairs of key/value in your ListArray. The item arrays may be of any length, like in jagged array.

Sometime I have seen this error when you are switching between the projects and running the projects on the same port one after the other. In that case goto chrome Developer Tools > Network and try to check the actual written js file for: if the file match with the workspce. To resolve this select Disable Cache under network.

Kotlin

You can use .toString directly on any data type in kotlin, like

val d : Double = 100.00
val string : String = d.toString()

thanks for the help, I've solved my problem :) Here is the code if anyone else needs it :D

import java.util.*;

public class HelloWorld {


public static void main(String[] Args) {

Map<Integer,List<Integer>> map = new HashMap<Integer,List<Integer>>();
List<Integer> list = new ArrayList<Integer>();
list.add(1);
list.add(9);
list.add(11);
map.put(1,list);        

    int First = list.get(1);
    int Second = list.get(2);

    if (First < Second) {

        System.out.println("One or more of your items have been restocked. The current stock is: " + First);

        Random rn = new Random();
int answer = rn.nextInt(99) + 1;

System.out.println("You are buying " + answer + " New stock");

First = First + answer;
list.set(1, First);
System.out.println("There are now " + First + " in stock");
}     
}  
}

I had a similar issue and found that pandas.get_dummies() solved the problem. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In your case, you would replace train_x = test[cols] with:

train_x = pandas.get_dummies(test[cols])

This transforms the train_x Dataframe into the following form, which RandomForestClassifier can accept:

   C  A_Hello  A_Hola  B_Bueno  B_Hi
0  0        1       0        0     1
1  1        0       1        1     0

I use the suffixes option in .merge():

dfNew = df.merge(df2, left_index=True, right_index=True,
                 how='outer', suffixes=('', '_y'))
dfNew.drop(dfNew.filter(regex='_y$').columns.tolist(),axis=1, inplace=True)

Thanks @ijoseph

Building upon @B.M answer, here is a more general version and updated to work with newer library version: (numpy version 1.19.2, pandas version 1.2.1) And this solution can also deal with multi-indices:

However this is not heavily tested, use with caution.

If performance is important go down to numpy level:

import pandas as pd
import numpy as np

np.random.seed(0)
df = pd.DataFrame({'a': np.random.randint(0, 10, 90), 'b': [1,2,3]*30, 'c':list('abcefghij')*10, 'd': list('hij')*30})


def f_multi(df,col_names):
    if not isinstance(col_names,list):
        col_names = [col_names]
        
    values = df.sort_values(col_names).values.T

    col_idcs = [df.columns.get_loc(cn) for cn in col_names]
    other_col_names = [name for idx, name in enumerate(df.columns) if idx not in col_idcs]
    other_col_idcs = [df.columns.get_loc(cn) for cn in other_col_names]

    # split df into indexing colums(=keys) and data colums(=vals)
    keys = values[col_idcs,:]
    vals = values[other_col_idcs,:]
    
    # list of tuple of key pairs
    multikeys = list(zip(*keys))
    
    # remember unique key pairs and ther indices
    ukeys, index = np.unique(multikeys, return_index=True, axis=0)
    
    # split data columns according to those indices
    arrays = np.split(vals, index[1:], axis=1)

    # resulting list of subarrays has same number of subarrays as unique key pairs
    # each subarray has the following shape:
    #    rows = number of non-grouped data columns
    #    cols = number of data points grouped into that unique key pair
    
    # prepare multi index
    idx = pd.MultiIndex.from_arrays(ukeys.T, names=col_names) 

    list_agg_vals = dict()
    for tup in zip(*arrays, other_col_names):
        col_vals = tup[:-1] # first entries are the subarrays from above 
        col_name = tup[-1]  # last entry is data-column name
        
        list_agg_vals[col_name] = col_vals

    df2 = pd.DataFrame(data=list_agg_vals, index=idx)
    return df2

You should use the new HttpClient. You can find more information here.

http
  .get<any>('url', {observe: 'response'})
  .subscribe(resp => {
    console.log(resp.headers.get('X-Token'));
  });

This is because PHP uses the period character . for string concatenation, not the plus character +. Therefore to append to a string you want to use the .= operator:

for ($i=1;$i<=100;$i++)
{
    $selectBox .= '<option value="' . $i . '">' . $i . '</option>';
}
$selectBox .= '</select>';

If anyone else had problems doing two transitions at once, here's what I did. I needed text to come from top to bottom on page load.

HTML

<body class="existing-class-name" onload="document.body.classList.add('loaded')">

HTML

<div class="image-wrapper">
    <img src="db-image.jpg" alt="db-image-name">
    <span class="text-over-image">DB text</span>
</div>

CSS

.text-over-image {
    position: absolute;
    background-color: rgba(110, 186, 115, 0.8);
    color: #eee;
    left: 0;
    width: 100%;
    padding: 10px;
    opacity: 0;
    bottom: 100%;
    -webkit-transition: opacity 2s, bottom 2s;
    -moz-transition: opacity 2s, bottom 2s;
    -o-transition: opacity 2s, bottom 2s;
    transition: opacity 2s, bottom 2s;
}

body.loaded .text-over-image {
    bottom: 0;
    opacity: 1;
}

Don't know why I kept trying to use 2 transition declarations in 1 selector and (not really) thinking it would use both.

Just install the updated versions of all of them.

apt-get install -y gnupg2 gnupg gnupg1

I am using Docker. I am trying to create a docker image that has all of my node dependencies installed, but can use my local app directory at container run time (without polluting it with a node_modules directory or link). This causes problems in this scenario. My workaround is to require from the exact path where the module, e.g. require('/usr/local/lib/node_modules/socket.io')

It is possibly because the value of val is actually the string "null" rather than the value null.

Just open your repository file and add this new function, then call it inside your controller:

 public function distinctCategories(){
        return $this->createQueryBuilder('cc')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->groupBy('cc.blogarticle')
        ->getQuery()
        ->getResult()
        ;
    }

Then within your controller:

public function index(YourRepository $repo)
{
    $distinctCategories = $repo->distinctCategories();


    return $this->render('your_twig_file.html.twig', [
        'distinctCategories' => $distinctCategories
    ]);
}

Good luck!

You don't need to wrap it in a list with [..], just provide the subselection of the columns index:

df.drop(df.columns[[1, 69]], axis=1, inplace=True)

as the index object is already regarded as list-like.

You can use JSON to convert it to dictionary

import json
data = b'{"key":"value"}'
print(json.loads(data))

{"key":"value"}

FLASK:

This is an example from flask. Run this on terminal line:

import requests
requests.post(url='http://localhost(example)/',json={'key':'value'})

In flask/routes.py

@app.route('/', methods=['POST'])
def api_script_add():
    print(request.data) # --> b'{"hi":"Hello"}'
    print(json.loads(request.data))
return json.loads(request.data)

{'key':'value'}

Here's also nice way to achieve this via UI.

Read this (supplementary) answer (that is sometimes the answer) to understand where this is going and why some people in this thread complain that "it is still not working"

I wrote exactly same code as one of the answers here. But I still had an issue. I placed break point on

var mi = o.GetType().GetMethod(methodName, BindingFlags.NonPublic | BindingFlags.Instance );

It executed but mi == null

And it continued behavior like this until I did "re-build" on all projects involved. I was unit testing one assembly while the reflection method was sitting in third assembly. It was totally confusing but I used Immediate Window to discover methods and I found that a private method I tried to unit test had old name (I renamed it). This told me that old assembly or PDB is still out there even if unit test project builds - for some reason project it tests didn't built. "rebuild" worked

I stumbled in the same problem while working on a web api Asp Net Core project. I followed the suggestion to change the reference in my code to:

ConfigurationManager.ConnectionStrings["NameOfTheConnectionString"].ConnectionString

but adding the reference to System.Configuration.dll caused the error "Reference not valid or not supported".

To fix the problem I had to download the package System.Configuration.ConfigurationManager using NuGet (Tools -> Nuget Package-> Manage Nuget packages for the solution)

The key is calling the parent's method using super.methodName();

class A {
    // A protected method
    protected doStuff()
    {
        alert("Called from A");
    }

    // Expose the protected method as a public function
    public callDoStuff()
    {
        this.doStuff();
    }
}

class B extends A {

    // Override the protected method
    protected doStuff()
    {
        // If we want we can still explicitly call the initial method
        super.doStuff();
        alert("Called from B");
    }
}

var a = new A();
a.callDoStuff(); // Will only alert "Called from A"

var b = new B()
b.callDoStuff(); // Will alert "Called from A" then "Called from B"

I had another requirement like only few stash have to be removed, below code would be helpful in that case.

#!/bin/sh
for i in `seq 5 8`
do
   git stash drop stash@{$i}
done

/* will delete from 5 to 8 index*/

With your example:

<input type="checkbox" id="c2" name="c2" value="DE039230952"/>

Replace $$ with document.querySelectorAll in the examples:

$$('input') //Every input
$$('[id]') //Every element with id
$$('[id="c2"]') //Every element with id="c2"
$$('input,[id]') //Every input + every element with id
$$('input[id]') //Every input including id
$$('input[id="c2"]') //Every input including id="c2"
$$('input#c2') //Every input including id="c2" (same as above)
$$('input#c2[value="DE039230952"]') //Every input including id="c2" and value="DE039230952"
$$('input#c2[value^="DE039"]') //Every input including id="c2" and value has content starting with DE039
$$('input#c2[value$="0952"]') //Every input including id="c2" and value has content ending with 0952
$$('input#c2[value*="39230"]') //Every input including id="c2" and value has content including 39230

Use the examples directly with:

const $$ = document.querySelectorAll.bind(document);

Some additions:

$$(.) //The same as $([class])
$$(div > input) //div is parent tag to input
document.querySelector() //equals to $$()[0] or $()

This is another option, using jQuery and getting only tbody rows (with the data) and desconsidering thead/tfoot.

$("#tableId > tbody > tr").length

console.log($("#myTableId > tbody > tr").length);

JSON (JavaScript Object Notation) is a lightweight format that is used for data interchanging. It is based on a subset of JavaScript language (the way objects are built in JavaScript). As stated in the MDN, some JavaScript is not JSON, and some JSON is not JavaScript.

An example of where this is used is web services responses. In the 'old' days, web services used XML as their primary data format for transmitting back data, but since JSON appeared (The JSON format is specified in RFC 4627 by Douglas Crockford), it has been the preferred format because it is much more lightweight

You can find a lot more info on the official JSON web site.

JSON is built on two structures:

• A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
• An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.

JSON Structure

Here is an example of JSON data:

{
     "firstName": "John",
     "lastName": "Smith",
     "address": {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": 10021
     },
     "phoneNumbers": [
         "212 555-1234",
         "646 555-4567"
     ]
 }

JSON in JavaScript

JSON (in Javascript) is a string!

People often assume all Javascript objects are JSON and that JSON is a Javascript object. This is incorrect.

In Javascript var x = {x:y} is not JSON, this is a Javascript object. The two are not the same thing. The JSON equivalent (represented in the Javascript language) would be var x = '{"x":"y"}'. x is an object of type string not an object in it's own right. To turn this into a fully fledged Javascript object you must first parse it, var x = JSON.parse('{"x":"y"}');, x is now an object but this is not JSON anymore.

See Javascript object Vs JSON

When working with JSON and JavaScript, you may be tempted to use the eval function to evaluate the result returned in the callback, but this is not suggested since there are two characters (U+2028 & U+2029) valid in JSON but not in JavaScript (read more of this here).

Therefore, one must always try to use Crockford's script that checks for a valid JSON before evaluating it. Link to the script explanation is found here and here is a direct link to the js file. Every major browser nowadays has its own implementation for this.

Example on how to use the JSON parser (with the json from the above code snippet):

//The callback function that will be executed once data is received from the server
var callback = function (result) {
    var johnny = JSON.parse(result);
    //Now, the variable 'johnny' is an object that contains all of the properties 
    //from the above code snippet (the json example)
    alert(johnny.firstName + ' ' + johnny.lastName); //Will alert 'John Smith'
};

The JSON parser also offers another very useful method, stringify. This method accepts a JavaScript object as a parameter, and outputs back a string with JSON format. This is useful for when you want to send data back to the server:

var anObject = {name: "Andreas", surname : "Grech", age : 20};
var jsonFormat = JSON.stringify(anObject);
//The above method will output this: {"name":"Andreas","surname":"Grech","age":20}

The above two methods (parse and stringify) also take a second parameter, which is a function that will be called for every key and value at every level of the final result, and each value will be replaced by result of your inputted function. (More on this here)

Btw, for all of you out there who think JSON is just for JavaScript, check out this post that explains and confirms otherwise.

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Hope this is your structure:

   <ul> 
     <li>
        <div ><img.. /><p>text</p></div>
    </li>
     <li>
        <div ><img.. /><p>text</p></div>
    </li>
     <li>
        <div ><img.. /><p>text</p></div>
    </li>
   </ul> 

By default, it will be add one after another row:

-----
-----
-----

if you want to make it vertical, just add float left to li, give width and height, make sure that content will not break the width:

|  |  |
|  |  |

li
{
   display:block;
   float:left;
   width:300px; /* adjust */
   height:150px; /* adjust */
   padding: 5px; /*adjust*/
}

Using the client instead of resource:

s3 = boto3.client('s3')
bucket='bucket_name'
result = s3.list_objects(Bucket = bucket, Prefix='/something/')
for o in result.get('Contents'):
    data = s3.get_object(Bucket=bucket, Key=o.get('Key'))
    contents = data['Body'].read()
    print(contents)

Try to use createChild() method of DOM or insertRow() and insertCell() method of table object in script tag.

this is pretty basic stuff, all you need to do is to create a base view model and make sure ALL! and i mean ALL! of your views that will ever use that layout will receive views that use that base model!

public class SomeViewModel : ViewModelBase
{
    public bool ImNotEmpty = true;
}

public class EmptyViewModel : ViewModelBase
{
}

public abstract class ViewModelBase
{
}

in the _Layout.cshtml:

@model Models.ViewModelBase
<!DOCTYPE html>
  <html>
  and so on...

in the the Index (for example) method in the home controller:

    public ActionResult Index()
    {
        var model = new SomeViewModel()
        {
        };
        return View(model);
    }

the Index.cshtml:

@model Models.SomeViewModel

@{
  ViewBag.Title = "Title";
  Layout = "~/Views/Shared/_Layout.cshtml";
}

<div class="row">

i disagree that passing a model to the _layout is an error, some user info can be passed and the data can be populate in the controllers inheritance chain so only one implementation is needed.

obviously for more advanced purpose you should consider creating custom static contaxt using injection and include that model namespace in the _Layout.cshtml.

but for basic users this will do the trick

The following will work for a DateTime that has fractional milliseconds, and also preserves the Kind property (Local, Utc or Undefined).

DateTime dateTime = ... anything ...
dateTime = new DateTime(
    dateTime.Ticks - (dateTime.Ticks % TimeSpan.TicksPerSecond), 
    dateTime.Kind
    );

or the equivalent and shorter:

dateTime = dateTime.AddTicks( - (dateTime.Ticks % TimeSpan.TicksPerSecond));

This could be generalized into an extension method:

public static DateTime Truncate(this DateTime dateTime, TimeSpan timeSpan)
{
    if (timeSpan == TimeSpan.Zero) return dateTime; // Or could throw an ArgumentException
    if (dateTime == DateTime.MinValue || dateTime == DateTime.MaxValue) return dateTime; // do not modify "guard" values
    return dateTime.AddTicks(-(dateTime.Ticks % timeSpan.Ticks));
}

which is used as follows:

dateTime = dateTime.Truncate(TimeSpan.FromMilliseconds(1)); // Truncate to whole ms
dateTime = dateTime.Truncate(TimeSpan.FromSeconds(1)); // Truncate to whole second
dateTime = dateTime.Truncate(TimeSpan.FromMinutes(1)); // Truncate to whole minute
...

The following is my solutions which works ( 5 steps )

Step1: Add an observer to catch which UITEXTFIELD or UITEXTVIEW ShoudBeginEditing ( where object is inited or ViewDidLoad.

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(updateActiveField:)
                                             name:@"UPDATE_ACTIVE_FIELD" object:nil];

Step2: Post a notification when ..ShouldBeginEditing with OBJECT of UITEXTFIELD or UITEXTVIEW

-(BOOL)textViewShouldBeginEditing:(UITextView *)textView {

[[NSNotificationCenter defaultCenter] postNotificationName:@"UPDATE_ACTIVE_FIELD" 
                                                    object:textView];
return YES;
}

Step3: The method that (Step1 calles ) assigns the current UITEXTFIELD or UITEXTVIEW

-(void) updateActiveField: (id) sender {
    activeField = [sender object];
}

Step4: Add Keyboard observer UIKeyboardWillShowNotification ( same place as Step1 )

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWasShown:)
                                             name:UIKeyboardDidShowNotification object:nil];

and method:

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);

    _currentEdgeInsets = self.layoutPanel.contentInset; // store current insets to restore them later
    self.layoutPanel.contentInset = contentInsets;
    self.layoutPanel.scrollIndicatorInsets = contentInsets;

    // If active text field is hidden by keyboard, scroll it so it's visible
    CGRect aRect =  self.view.frame;
    aRect.size.height -= kbSize.height;

    UIWindow *window = [[UIApplication sharedApplication] keyWindow];
    CGPoint p = [activeField convertPoint:activeField.bounds.origin toView:window];

    if (!CGRectContainsPoint(aRect, p) ) {
        CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y +kbSize.height);
       [self.layoutPanel setContentOffset:scrollPoint animated:YES];
       self.layoutPanel.scrollEnabled = NO;
    }
}

Step5: Add Keyboard observer UIKeyboardWillHideNotification ( same place as step 1 )

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillBeHidden:)
                                                 name:UIKeyboardWillHideNotification object:nil];

and method:

// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    self.layoutPanel.contentInset = _currentEdgeInsets;
    self.layoutPanel.scrollIndicatorInsets = _currentEdgeInsets;
    self.layoutPanel.scrollEnabled = YES;
}

Remember to remove observers!

The pseudo-code "implementation" of strcmp would go something like:

define strcmp (s1, s2):
    p1 = address of first character of str1
    p2 = address of first character of str2

    while contents of p1 not equal to null:
        if contents of p2 equal to null: 
            return 1

        if contents of p2 greater than contents of p1:
            return -1

        if contents of p1 greater than contents of p2:
            return 1

        advance p1
        advance p2

    if contents of p2 not equal to null:
        return -1

    return 0

That's basically it. Each character is compared in turn an a decision is made as to whether the first or second string is greater, based on that character.

Only if the characters are identical do you move to the next character and, if all the characters were identical, zero is returned.

Note that you may not necessarily get 1 and -1, the specs say that any positive or negative value will suffice, so you should always check the return value with < 0, > 0 or == 0.

Turning that into real C would be relatively simple:

int myStrCmp (const char *s1, const char *s2) {
    const unsigned char *p1 = (const unsigned char *)s1;
    const unsigned char *p2 = (const unsigned char *)s2;

    while (*p1 != '\0') {
        if (*p2 == '\0') return  1;
        if (*p2 > *p1)   return -1;
        if (*p1 > *p2)   return  1;

        p1++;
        p2++;
    }

    if (*p2 != '\0') return -1;

    return 0;
}

Also keep in mind that "greater" in the context of characters is not necessarily based on simple ASCII ordering for all string functions.

C has a concept called 'locales' which specify (among other things) collation, or ordering of the underlying character set and you may find, for example, that the characters a, á, à and ä are all considered identical. This will happen for functions like strcoll.

assuming certain column names...

INSERT one

newToner = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

dbsession.add(newToner)   
dbsession.commit()

INSERT multiple

newToner1 = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

newToner2 = Toner(toner_id = 2,
                    toner_color = 'red',
                    toner_hex = '#F01731')

dbsession.add_all([newToner1, newToner2])   
dbsession.commit()

UPDATE

q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'

dbsession.commit()

or using a fancy one-liner using MERGE

record = dbsession.merge(Toner( **kwargs))

In addition to the ioctl() method Filip demonstrated you can use getifaddrs(). There is an example program at the bottom of the man page.

Take it from someone who has tried it all three ways... just use a varchar(39)

The slightly less efficient storage far outweighs any benefit of having to convert it on insert/update and format it when showing it anywhere.

app.use() is intended for binding middleware to your application. The path is a "mount" or "prefix" path and limits the middleware to only apply to any paths requested that begin with it. It can even be used to embed another application:

// subapp.js
var express = require('express');
var app = modules.exports = express();
// ...

// server.js
var express = require('express');
var app = express();

app.use('/subapp', require('./subapp'));

// ...

By specifying / as a "mount" path, app.use() will respond to any path that starts with /, which are all of them and regardless of HTTP verb used:

• GET /
• PUT /foo
• POST /foo/bar
• etc.

app.get(), on the other hand, is part of Express' application routing and is intended for matching and handling a specific route when requested with the GET HTTP verb:

• GET /

And, the equivalent routing for your example of app.use() would actually be:

app.all(/^\/.*/, function (req, res) {
    res.send('Hello');
});

(Update: Attempting to better demonstrate the differences.)

The routing methods, including app.get(), are convenience methods that help you align responses to requests more precisely. They also add in support for features like parameters and next('route').

Within each app.get() is a call to app.use(), so you can certainly do all of this with app.use() directly. But, doing so will often require (probably unnecessarily) reimplementing various amounts of boilerplate code.

Examples:

• For simple, static routes:

  app.get('/', function (req, res) {
    // ...
  });
  

  vs.

  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    // ...
  });
  

• With multiple handlers for the same route:

  app.get('/', authorize('ADMIN'), function (req, res) {
    // ...
  });
  

  vs.

  const authorizeAdmin = authorize('ADMIN');
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    authorizeAdmin(req, res, function (err) {
      if (err) return next(err);
  
      // ...
    });
  });
  

• With parameters:

  app.get('/item/:id', function (req, res) {
    let id = req.params.id;
    // ...
  });
  

  vs.

  const pathToRegExp = require('path-to-regexp');
  
  function prepareParams(matches, pathKeys, previousParams) {
    var params = previousParams || {};
  
    // TODO: support repeating keys...
    matches.slice(1).forEach(function (segment, index) {
      let { name } = pathKeys[index];
      params[name] = segment;
    });
  
    return params;
  }
  
  const itemIdKeys = [];
  const itemIdPattern = pathToRegExp('/item/:id', itemIdKeys);
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET') return next();
  
    var urlMatch = itemIdPattern.exec(req.url);
    if (!urlMatch) return next();
  
    if (itemIdKeys && itemIdKeys.length)
      req.params = prepareParams(urlMatch, itemIdKeys, req.params);
  
    let id = req.params.id;
    // ...
  });
  

Note: Express' implementation of these features are contained in its Router, Layer, and Route.

If you don't want to go the SMO route you can search and replace "GO" for ";" and the query as you would. Note that soly the the last result set will be returned.

If you are trying to debug your virtual host configuration, you may find the Apache -S command line switch useful. That is, type the following command:

httpd -S

This command will dump out a description of how Apache parsed the configuration file. Careful examination of the IP addresses and server names may help uncover configuration mistakes. (See the docs for the httpd program for other command line options).

No need to care of whether before/after this digit having other type of words

To just match the pattern of 5 digits number anywhere in the string, no matter it is separated by space or not, use this regular expression (?<!\d)\d{5}(?!\d).

Sample JavaScript codes:

var regexp = new RegExp(/(?<!\d)\d{5}(?!\d)/g); 
    var matches = yourstring.match(regexp);
    if (matches && matches.length > 0) {
        for (var i = 0, len = matches.length; i < len; i++) {
            // ... ydo something with matches[i] ...
        } 
    }

Here's some quick results.

• abc12345xyz (?)

• 12345abcd (?)

• abcd12345 (?)

• 0000aaaa2 (?)

• a1234a5 (?)

• 12345 (?)

• <space>12345<space>12345 (??)
