I believe it means 'anything but a whitespace character'.

From performance point of view the best is to use a sorted list so that data is sorted as it is added to result. Other approaches need at least one extra iteration on data and most create a copy of data so not only performance but memory usage will be affected too. Might not be an issue with couple of hundreds of elements but will be with thousands, especially in services where many concurrent requests may do sorting at the same time. Have a look at System.Collections.Generic namespace and choose a class with sorting instead of List.

And avoid generic implementations using reflection when possible, this can cause performance issues too.

Assuming you just want everything before \n (or any other literal string/char), you should use indexOf() with substring():

result = result.substring(0, result.indexOf('\n'));

If you want to extract the portion before a certain regular expression, you can use split():

result = result.split(regex, 2)[0];

String result = "34.1 -118.33\n<!--ABCDEFG-->";

System.out.println(result.substring(0, result.indexOf('\n')));
System.out.println(result.split("\n", 2)[0]);

34.1 -118.33
34.1 -118.33

(Obviously \n isn't a meaningful regular expression, I just used it to demonstrate that the second approach also works.)

Login to any other EC2 instance you have that has access to the RDS instance in question and has mysqladmin installed and run

I was just faced with a similar problem. I exported the contents of the db into one sql file and used TextEdit to find and replace everything I needed. Simplicity ftw!

U can use eclipse. but u need to download pydev addon for that.

objectForKey will return nil if a key doesn't exist.

I find using str.format much more elegant:

>>> '{0: <5}'.format('s')
's    '
>>> '{0: <5}'.format('ss')
'ss   '
>>> '{0: <5}'.format('sss')
'sss  '
>>> '{0: <5}'.format('ssss')
'ssss '
>>> '{0: <5}'.format('sssss')
'sssss'

If you want to align the string to the right use > instead of <:

>>> '{0: >5}'.format('ss')
'   ss'

Edit 1: As mentioned in the comments: the 0 in '{0: <5}' indicates the argument’s index passed to str.format().

Edit 2: In python3 one could use also f-strings:

sub_str='s'
for i in range(1,6):
    s = sub_str*i
    print(f'{s:>5}')
    
'    s'
'   ss'
'  sss'
' ssss'
'sssss'

or:

for i in range(1,5):
    s = sub_str*i
    print(f'{s:<5}')
's    '
'ss   '
'sss  '
'ssss '
'sssss'

of note, in some places above, ' ' (single quotation marks) were added to emphasize the width of the printed strings.

You can use literal quoting:

stmt := q'[insert into MY_TBL (Col) values('ER0002')]';

Documentation for literals can be found here.

Alternatively, you can use two quotes to denote a single quote:

stmt := 'insert into MY_TBL (Col) values(''ER0002'')';

The literal quoting mechanism with the Q syntax is more flexible and readable, IMO.

onStart() means Activity entered into visible state and layout is created but can't interact with this activity layout.

Resume() means now you can do interaction with activity layout.

In the AVD setup: Change the CPU/ABI option to MIPS. It worked for me

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

In some cases adding "Option Strict On" in VB.NET and resolving all issues it finds by proper casting has solved this problem for me.

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

For narrowing the type of the property, simple extend works perfect, as in Nitzan's answer:

interface A {
    x: string | number;
}

interface B extends A {
    x: number;
}

For widening, or generally overriding the type, you can do Zskycat's solution:

interface A {
    x: string
}

export type B = Omit<A, 'x'> & { x: number };

But, if your interface A is extending a general interface, you will lose the custom types of A's remaining properties when using Omit.

e.g.

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = Omit<A, 'x'> & { x: number };

let b: B = { x: 2, y: "hi" }; // no error on b.y! 

The reason is, Omit internally only goes over Exclude<keyof A, 'x'> keys which will be the general string | number in our case. So, B would become {x: number; } and accepts any extra property with the type of number | string | boolean.

To fix that, I came up with a different OverrideProps utility type as following:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

Example:

type OverrideProps<M, N> = { [P in keyof M]: P extends keyof N ? N[P] : M[P] };

interface A extends Record<string | number, number | string | boolean> {
    x: string;
    y: boolean;
}

export type B = OverrideProps<A, { x: number }>;

let b: B = { x: 2, y: "hi" }; // error: b.y should be boolean!

Edit: While I agree with the commenter who said "censorship is wrong", that is not the nature of this answer.

In a HashMap the key is an object, that contains hashCode() and equals(Object) methods.

When you insert a new entry into the Map, it checks whether the hashCode is already known. Then, it will iterate through all objects with this hashcode, and test their equality with .equals(). If an equal object is found, the new value replaces the old one. If not, it will create a new entry in the map.

Usually, talking about maps, you use collision when two objects have the same hashCode but they are different. They are internally stored in a list.

The problem: The format of the file as to how it is saved. Use a proper text editor and save it with the .py extension and run it in terminal.

eg: file name should be saved as `example.py`
run
python example

1. Do a right click->properties on the file in Visual Studio.
2. Set the Copy to Output Directory to Copy always.

Then you will be able to reference your files by using a path such as @".\my_html.html"

Copy to Output Directory will put the file in the same folder as your binary dlls when the project is built. This works with any content file, even if its in a sub folder.

If you use a sub folder, that too will be copied in to the bin folder so your path would then be @".\my_subfolder\my_html.html"

In order to create a URI you can use locally (instead of served via the web), you'll need to use the file protocol, using the base directory of your binary - note: this will only work if you set the Copy to Ouptut Directory as above or the path will not be correct.

This is what you need:

string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Url = new Uri(String.Format("file:///{0}/my_html.html", curDir));

You'll have to change the variables and names of course.

You can multiply numpy arrays by scalars and it just works.

>>> import numpy as np
>>> np.array([1, 2, 3]) * 2
array([2, 4, 6])
>>> np.array([[1, 2, 3], [4, 5, 6]]) * 2
array([[ 2,  4,  6],
       [ 8, 10, 12]])

This is also a very fast and efficient operation. With your example:

>>> a_1 = np.array([1.0, 2.0, 3.0])
>>> a_2 = np.array([[1., 2.], [3., 4.]])
>>> b = 2.0
>>> a_1 * b
array([2., 4., 6.])
>>> a_2 * b
array([[2., 4.],
       [6., 8.]])

Java 8 has the option of using streams like:

List<Object> lst = new ArrayList<>();
String[] strings = lst.stream().toArray(String[]::new);

By looping it can be done the following way :)

num1= int(input('Enter the number'))
sum1 = num1 #making a alt int to store the value of the orginal so it wont be affected
y = [] #making a list 
while True:
    if(sum1==0):#checking if the number is not zero so it can break if it is
        break
    d = sum1%10 #last number of your integer is saved in d
    sum1 = int(sum1/10) #integer is now with out the last number ie.4320/10 become 432
    y.append(d) # appending the last number in the first place

y.reverse()#as last is in first , reversing the number to orginal form
print(y)

Answer becomes

Enter the number2342

                                   1) for i in xrange(0,total_months) ]
    return month_list

This is first computing the total number of months between the two dates, inclusive. Then it creates a list using the first date as the base and performs modula arithmetic to create the date objects.

Please Note: The original poster was not specifically asking about PHP. All the php centric answers make large assumptions not relevant to the actual question.

The default error log as opposed to the scripts error logs usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found.

This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error.

in perl if you forget

print "content-type: text/html\r\n\r\n";

you will get this error

There are many reasons for it. so please first check your error log and then provide some more information.

The default error log is often in /var/log/httpd/error_log or /var/log/apache2/error.log.

The reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host.

Assumes linux and not necessarily perl

Instead of using JTextArea.setText(String text), use JTextArea.append(String text).

Appends the given text to the end of the document. Does nothing if the model is null or the string is null or empty.

This will add text on to the end of your JTextArea.

Another option would be to use getText() to get the text from the JTextArea, then manipulate the String (add or remove or change the String), then use setText(String text) to set the text of the JTextArea to be the new String.

This article explains all the details http://kunststube.net/encoding/

WRITING TO BUFFER

if you write to a 4 byte buffer, symbol ? with UTF8 encoding, your binary will look like this:

00000000 11100011 10000001 10000010

if you write to a 4 byte buffer, symbol ? with UTF16 encoding, your binary will look like this:

00000000 00000000 00110000 01000010

As you can see, depending on what language you would use in your content this will effect your memory accordingly.

e.g. For this particular symbol: ? UTF16 encoding is more efficient since we have 2 spare bytes to use for the next symbol. But it doesn't mean that you must use UTF16 for Japan alphabet.

READING FROM BUFFER

Now if you want to read the above bytes, you have to know in what encoding it was written to and decode it back correctly.

e.g. If you decode this : 00000000 11100011 10000001 10000010 into UTF16 encoding, you will end up with ? not ?

Note: Encoding and Unicode are two different things. Unicode is the big (table) with each symbol mapped to a unique code point. e.g. ? symbol (letter) has a (code point): 30 42 (hex). Encoding on the other hand, is an algorithm that converts symbols to more appropriate way, when storing to hardware.

30 42 (hex) - > UTF8 encoding - > E3 81 82 (hex), which is above result in binary.

30 42 (hex) - > UTF16 encoding - > 30 42 (hex), which is above result in binary.

As noted above, it appears that the cover photo of the profile album is a hi-res profile picture. I would check for the album type of "profile" rather than the name though, as the name may not be consistent across different languages, but the type should be.

To reduce the number of requests / parsing, you can use this fql: "select cover_object_id from album where type='profile' and owner = user_id"

And then you can construct the image url with: "https://graph.facebook.com/" + cover_object_id + "/picture&type=normal&access_token=" + access_token

Looks like there is no "large" type for this image, but the "normal" one is still quite large.

As noted above, this photo may be less accessible than the public profile picture. You need the user_photos or friend_photos permission to access it.

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

I know this is an old thread, but I was running into the same problem and found HashSet to be very unreliable because given the same seed, GetHashCode() returned different codes. So, I thought, why not just use a List and hide the add method like this

public class UniqueList<T> : List<T>
{
    public new void Add(T obj)
    {
        if(!Contains(obj))
        {
            base.Add(obj);
        }
    }
}

Because List uses the Equals method solely to determine equality, you can define the Equals method on your T type to make sure you get the desired results.

Adapted from Richard Ayotte's code - To target an img in a ul/li list (found via wrapper div class here), something like this:

$('div.navlist li').bind('mouseenter mouseleave', function() {    
    $(this).find('img').attr({ src: $(this).find('img').attr('data-alt-src'), 
    'data-alt-src':$(this).find('img').attr('src') }
); 

In Python 3, print is a function, you need to call it like print("hello world").

This will do:

/^(apple|banana)$/

to exclude from captured strings (e.g. $1,$2):

(?:apple|banana)

Yes, it's possible. for example checkout:

<div class="singleMatch" ng-if="match.date | date:'ddMMyyyy' === main.date &&  match.team1.code === main.team1code && match.team2.code === main.team2code">
    //Do something here
    </div>

Simple example that works with Java 1.7 to recursively list files in directories specified on the command-line:

import java.io.File;

public class List {
    public static void main(String[] args) {
        for (String f : args) {
            listDir(f);
        }
    }

    private static void listDir(String dir) {
        File f = new File(dir);
        File[] list = f.listFiles();

        if (list == null) {
            return;
        }

        for (File entry : list) {
            System.out.println(entry.getName());
            if (entry.isDirectory()) {
                listDir(entry.getAbsolutePath());
            }
        }
    }
}

This worked for me just by restarting android studio 2 times :D. I'm using Android Studio 2.1.

There's no need to use onAuthStateChanged() function in this scenario.

You can easily detect if the user is logged or not by executing:

var user = firebase.auth().currentUser;

For those who face the "returning null" issue, it's just because you are not waiting for the firebase call to complete.

Let's suppose you perform the login action on Page A and then you invoke Page B, on Page B you can call the following JS code to test the expected behavior:

  var config = {
    apiKey: "....",
    authDomain: "...",
    databaseURL: "...",
    projectId: "..",
    storageBucket: "..",
    messagingSenderId: ".."
  };
  firebase.initializeApp(config);

    $( document ).ready(function() {
        console.log( "testing.." );
        var user = firebase.auth().currentUser;
        console.log(user);
    });

If the user is logged then "var user" will contain the expected JSON payload, if not, then it will be just "null"

And that's all you need.

Just use $evalAsync instead of $apply.

It's hard to escape a single quote within single quotes. Try this:

sed "s@['\"]http://www.\([^.]\+).com['\"]@URL_\U\1@g" 

Example:

$ sed "s@['\"]http://www.\([^.]\+\).com['\"]@URL_\U\1@g" <<END
this is "http://www.fubar.com" and 'http://www.example.com' here
END

produces

this is URL_FUBAR and URL_EXAMPLE here

<system.webServer>
   <modules runAllManagedModulesForAllRequests="true"/> 
 </system.webServer>

U can use above code

You could use .contents() method of jQuery.

The .contents() method can also be used to get the content document of an iframe, if the iframe is on the same domain as the main page.

$(document).ready(function(){
    $('#frameID').load(function(){
        $('#frameID').contents().find('body').html('Hey, i`ve changed content of <body>! Yay!!!');
    });
});

The simplest solution is to apply Python str function to the column you are trying to loop through.

If you are using pandas, this can be implemented as:

dataframe['column_name']=dataframe['column_name'].apply(str)

I came across this problem and my senior told me about a solution i.e:

Right click on your projectname.xcodeproj file here projectname will be the name of your project. Now after right clicked select Show Packages Contents. After that open your projectname.pbxproj file in a text editor. Now search for the line containing <<<<<<< .mine, ======= and >>>>>>> .r. For example in my case it looked liked this

<<<<<<< .mine
    9ADAAC6A15DCEF6A0019ACA8 .... in Resources */,
=======
    52FD7F3D15DCEAEF009E9322 ... in Resources */,
>>>>>>> .r269

Now remove those <<<<<<< .mine, ======= and >>>>>>> .r lines so it would look like this

    9ADAAC6A15DCEF6A0019ACA8 /* BuyPriceBtn.png in Resources */,

    52FD7F3D15DCEAEF009E9322 /* discussionForm.zip in Resources */,

Now save and open your Xcode project and build it. Everything will be fine.

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

Percent encoding. Replace the hash with %23.

Use asp:Panel for that. It translates into a div.

cur.execute( "SELECT * FROM records WHERE email LIKE %s", (search,) )

I do not why, but this works for me . rather than use '%s'.

Instead of - fd.append( 'userfile', $('#userfile')[0].files[0]);

Use - fd.append( 'file', $('#userfile')[0].files[0]);

For other future users who do not want to make their controllers asynchronous, or cannot access the HttpContext, or are using dotnet core (this answer is the first I found on Google trying to do this), the following worked for me:

[HttpPut("{pathId}/{subPathId}"),
public IActionResult Put(int pathId, int subPathId, [FromBody] myViewModel viewModel)
{

    var body = new StreamReader(Request.Body);
    //The modelbinder has already read the stream and need to reset the stream index
    body.BaseStream.Seek(0, SeekOrigin.Begin); 
    var requestBody = body.ReadToEnd();
    //etc, we use this for an audit trail
}

https://www.npmjs.com/package/babel-register

// This is to allow ES6 export syntax
// to be properly read and processed by node.js application
require('babel-register')({
  presets: [

});

// After that, any line you add below that has typical ES6 export syntax
// will work just fine

const utils = require('../../utils.js');
const availableMixins = require('../../../src/lib/mixins/index.js');

Below is definition of file *mixins/index.js

That worked just fine inside my Node.js CLI application.

For Python >= 2.7, use subprocess.check_output().

The actual representation of a null pointer is irrelevant here. An integer literal with value zero (including 0 and any valid definition of NULL) can be converted to any pointer type, giving a null pointer, whatever the actual representation. So p != NULL, p != 0 and p are all valid tests for a non-null pointer.

You might run into problems with non-zero representations of the null pointer if you wrote something twisted like p != reinterpret_cast<void*>(0), so don't do that.

Although I've just noticed that your question is tagged C as well as C++. My answer refers to C++, and other languages may be different. Which language are you using?

GraphQL query format was designed in order to allow:

1. Both query and result shape be exactly the same.
2. The server knows exactly the requested fields, thus the client downloads only essential data.

However, according to GraphQL documentation, you may create fragments in order to make selection sets more reusable:

# Only most used selection properties

fragment UserDetails on User {
    id,
    username
} 

Then you could query all user details by:

FetchUsers {
    users() {
        ...UserDetails
    }
}

You can also add additional fields alongside your fragment:

FetchUserById($id: ID!) {
    users(id: $id) {
        ...UserDetails
        count
    }
}

This one is Best in my case

    var value = $(this).val().toLowerCase();
    $("#myTable tr").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});
</script>

If you need rock solid integrity, have both tables in one database, and use an FK constraint. If your parent table is in another database, nothing prevents anyone from restoring that parent database from an old backup, and then you have orphans.

This is why FK between databases is not supported.

I would suggest TARGET_FILE_DIR if you want the file to be copied to the same folder as your .exe file.

$ Directory of main file (.exe, .so.1.2, .a).

  COMMAND ${CMAKE_COMMAND} -E copy 
    ${CMAKE_CURRENT_SOURCE_DIR}/input.txt 
    $<TARGET_FILE_DIR:${PROJECT_NAME}>)

In VS, this cmake script will copy input.txt to the same file as your final exe, no matter it's debug or release.

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____ 

(extract from the implementation)

Sometime we get this error when we select static character as a field in source query/view/procedure and the destination field data type in Unicode.

Below is the issue i faced: I used the script below at source

and got the error message Column "CATEGORY" cannot convert between Unicode and non-Unicode string data types. as below: error message

Resolution: I tried multiple options but none worked for me. Then I prefixed the static value with N to make in Unicode as below:

SELECT N'STUDENT DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM STUDENTS
UNION
SELECT N'FACULTY DETAIL' CATEGORY, NAME, DATEOFBIRTH FROM FACULTY

The question is already answered (BTW, really good and comprehensive answer provided by Ben), but I would like to add another element for completeness, which may be also very handy.

In the example suggested by Ben:

<select ng-model="blah" ng-options="item.ID as item.Title for item in items"></select>

the following ngOptions form has been used: select as label for value in array.

Label is an expression, which result will be the label for <option> element. In that case you can perform certain string concatenations, in order to have more complex option labels.

Examples:

• ng-options="item.ID as item.Title + ' - ' + item.ID for item in items" gives you labels like Title - ID
• ng-options="item.ID as item.Title + ' (' + item.Title.length + ')' for item in items" gives you labels like Title (X), where X is length of Title string.

You can also use filters, for example,

• ng-options="item.ID as item.Title + ' (' + (item.Title | uppercase) + ')' for item in items" gives you labels like Title (TITLE), where Title value of Title property and TITLE is the same value but converted to uppercase characters.
• ng-options="item.ID as item.Title + ' (' + (item.SomeDate | date) + ')' for item in items" gives you labels like Title (27 Sep 2015), if your model has a property SomeDate

Because I have to write a decimal number in a xml file I have find out the problem. In this discussion I have learned that xml file standard use dot for decimal value and this is culture independent. So my solution is write dot decimal number in a xml file and convert the readed string from the same xml file mystring.Replace(".", ","); Thanks Agat for suggestion to research the problem in xml context and ? ? ? ? ? ? because I didn't know visual studio doesn't respect the culture settings I have in my code.

In regards Jared's response, having Windows 2000 or better will not necessarily fix the issue at hand. Rob's response does work, however it is possible that this fix introduces security issues, as Windows updates will not be able to patch applications built as such.

In another post, Nick Guerrera suggests packaging the Visual C++ Runtime Redistributable with your applications, which installs quickly, and is independent of Visual Studio.

create an array of ones; multiply each list times the array; convert array to a list

import numpy as np

a = [1,2,3,4]
b = [2,3,4,5]

c = (np.ones(len(a))*a*b).tolist()

[2.0, 6.0, 12.0, 20.0]

Here is an appendTo version using the html dropdown you mentioned. It inserts another row on "change".

$('#dropdown').on( 'change', function(e) {
    $('#table').append('<tr><td>COL1</td><td>COL2</td></tr>');
});

With an example for you to play with. Best of luck!

Additional info to generate absolute URL using a command (to send an email for instance)

In a command, {{ absolute_url(path('index')) }} is not working out of the box.

You will need to add the additional configuration shown in antongorodezkiy's answer.

But in case you don't want to change the configuration because you are not sure how it could impact the whole app, you can configure the router in the command.

Here is the doc :

https://symfony.com/doc/3.4/console/request_context.html

Here is the code :

use Symfony\Component\Routing\RouterInterface;
// ...

class DemoCommand extends Command
{
    private $router;

    public function __construct(RouterInterface $router)
    {
        parent::__construct();

        $this->router = $router;
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $context = $this->router->getContext();
        $context->setHost('example.com');
        $context->setScheme('https');
        $context->setBaseUrl('my/path');

        $url = $this->router->generate('route-name', ['param-name' => 'param-value']);
        // ...
    }
}

To generate the URL in the Twig template

<a href="{{ absolute_url(path(...)) }}"></a>

You can fetch the HOST and SCHEME from your env file

$context = $this->router->getContext();
$context->setHost($_ENV['NL_HOST']);
$context->setScheme($_ENV['NL_SCHEME']);

Just define the variable in .env and .env.local files

NL_HOST=mydomain.com
NL_SCHEME=https

This problem occurs when the controller or directive are not specified as a array of dependencies and function. For example

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html',
        controller: function ($scope) {
            $scope.selectThisOption = function () {
                // some code
            };
        }
    };
});

When minified The '$scope' passed to the controller function is replaced by a single letter variable name . This will render angular clueless of the dependency . To avoid this pass the dependency name along with the function as a array.

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html'
        controller: ['$scope', function ($scope) { //<-- difference
            $scope.selectThisOption = function () {
                // some code
            };
        }]
    };
});

This is not related to performance at all. But consider this: you are using two libraries called Foo and Bar:

using namespace foo;
using namespace bar;

Everything works fine, and you can call Blah() from Foo and Quux() from Bar without problems. But one day you upgrade to a new version of Foo 2.0, which now offers a function called Quux(). Now you've got a conflict: Both Foo 2.0 and Bar import Quux() into your global namespace. This is going to take some effort to fix, especially if the function parameters happen to match.

If you had used foo::Blah() and bar::Quux(), then the introduction of foo::Quux() would have been a non-event.

Other useful registers:

"* or "+ - the contents of the system clipboard

"/ - last search command

": - last command-line command.

Note with vim macros, you can edit them, since they are just a list of the keystrokes used when recording the macro. So you can write to a text file the macro (using "ap to write macro a) and edit them, and load them into a register with "ay$. Nice way of storing useful macros.

Take a look at Beaker:

• Caching Documentation
• Good quick-start article about using Beaker with Django (but useful in any other apps too)

user2532030's answer is the correct and most simple answer.

I just want to add, that in the case, where the value of the determining cell is not suitable for a RegEx-match, I found the following syntax to work the same, only with numerical values, relations et.c.:

[Custom formula is]
=$B$2:$B = "Complete"
Range: A2:Z1000

If column 2 of any row (row 2 in script, but the leading $ means, this could be any row) textually equals "Complete", do X for the Range of the entire sheet (excluding header row (i.e. starting from A2 instead of A1)).

But obviously, this method allows also for numerical operations (even though this does not apply for op's question), like:

=$B$2:$B > $C$2:$C

So, do stuff, if the value of col B in any row is higher than col C value.

One last thing: Most likely, this applies only to me, but I was stupid enough to repeatedly forget to choose Custom formula is in the drop-down, leaving it at Text contains. Obviously, this won't float...

Google recommend that you don't use any of them, source.

There is no need to use entity references like &mdash, &rdquo, or &#x263a, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.

Is there a reason you can't simply use "?

Not only are you reading the whole of each file into memory, but also you laboriously replicate the information in a table called list_of_lines.

You have a secondary problem: your choices of variable names severely obfuscate what you are doing.

Here is your script rewritten with the readlines() caper removed and with meaningful names:

file_A1_B1 = open("A1_B1_100000.txt", "r")
file_A2_B2 = open("A2_B2_100000.txt", "r")
file_A1_B2 = open("A1_B2_100000.txt", "r")
file_A2_B1 = open("A2_B1_100000.txt", "r")
file_write = open ("average_generations.txt", "w")
mutation_average = open("mutation_average", "w") # not used
files = [file_A2_B2,file_A2_B2,file_A1_B2,file_A2_B1]
for afile in files:
    table = []
    for aline in afile:
        values = aline.split('\t')
        values.remove('\n') # why?
        table.append(values)
    row_count = len(table)
    row0length = len(table[0])
    print_counter = 4
    for column_index in range(row0length):
        column_total = 0
        for row_index in range(row_count):
            number = float(table[row_index][column_index])
            column_total = column_total + number
        column_average = column_total/row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1
file_write.write('\n')

It rapidly becomes apparent that (1) you are calculating column averages (2) the obfuscation led some others to think you were calculating row averages.

As you are calculating column averages, no output is required until the end of each file, and the amount of extra memory actually required is proportional to the number of columns.

Here is a revised version of the outer loop code:

for afile in files:
    for row_count, aline in enumerate(afile, start=1):
        values = aline.split('\t')
        values.remove('\n') # why?
        fvalues = map(float, values)
        if row_count == 1:
            row0length = len(fvalues)
            column_index_range = range(row0length)
            column_totals = fvalues
        else:
            assert len(fvalues) == row0length
            for column_index in column_index_range:
                column_totals[column_index] += fvalues[column_index]
    print_counter = 4
    for column_index in column_index_range:
        column_average = column_totals[column_index] / row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1

To find files accessed 1, 2, or 3 minutes ago use -3

find . -cmin -3

This is old topic but on my last test on one my API, cURL is faster and more stable. Sometimes file_get_contents on larger request need over 5 seconds when cURL need only from 1.4 to 1.9 seconds what is double faster.

I need to add one note on this that I just send GET and recive JSON content. If you setup cURL properly, you will have a great response. Just "tell" to cURL what you need to send and what you need to recive and that's it.

On your exampe I would like to do this setup:

$ch =  curl_init('http://api.bitly.com/v3/shorten?login=user&apiKey=key&longUrl=url');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 3);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
$result = curl_exec($ch);

This request will return data in 0.10 second max

Felix Kling did a great comparison on those two, for anyone wondering how to do an export default alongside named exports with module.exports in nodejs

module.exports = new DAO()
module.exports.initDAO = initDAO // append other functions as named export

// now you have
let DAO = require('_/helpers/DAO');
// DAO by default is exported class or function
DAO.initDAO()

$(this) is a jQuery object that is wrapping the DOM element this and jQuery objects don't have id properties. You probably want just this.id to get the id attribute of the clicked element.

A year after the question, I had to find an answer for this question as non of these gave the actual answer, at least to me.

You have asked how to select the option, but nobody has said that these two things are NOT the same:

If we have an options like this:

$scope.options = [
    { label: 'one', value: 1 },
    { label: 'two', value: 2 }
  ];

And we try to set a default option like this:

$scope.incorrectlySelected = { label: 'two', value: 2 };

It will NOT work, but if you try to select the option like this:

$scope.correctlySelected = $scope.options[1];

It will WORK.

Even though these two objects have the same properties, AngularJS is considering them as DIFFERENT because AngularJS compares by the reference.

Take a look at the fiddle http://jsfiddle.net/qWzTb/.

DEVELOPER runs autoconf and automake:

1. autoconf -- creates shippable configure script
   (which the installer will later run to make the Makefile)

• ‘autoconf’ is a macro processor.
• It converts configure.ac, which is a shell script using macro instructions, into configure, a full-fledged shell script.

2. automake - creates shippable Makefile.in data file
   (which configure will later read to make the Makefile)

• Automake helps with creating portable and GNU-standard compliant Makefiles.
• ‘automake’ creates complex Makefile.ins from simple Makefile.ams

INSTALLER runs configure, make and sudo make install:

./configure       # Creates  Makefile        (from     Makefile.in).  
make              # Creates  the application (from the Makefile just created).  

sudo make install # Installs the application 
                  #   Often, by default its files are installed into /usr/local

INPUT/OUTPUT MAP

Notation below is roughly: inputs --> programs --> outputs

DEVELOPER runs these:

configure.ac -> autoconf -> configure (script) --- (*.ac = autoconf)
configure.in --> autoconf -> configure (script) --- (configure.in depreciated. Use configure.ac)

Makefile.am -> automake -> Makefile.in ----------- (*.am = automake)

INSTALLER runs these:

Makefile.in -> configure -> Makefile (*.in = input file)

Makefile -> make ----------> (puts new software in your downloads or temporary directory)
Makefile -> make install -> (puts new software in system directories)

"autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls."

"automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards. Automake requires the use of Autoconf."

Manuals:

• GNU AutoTools (The definitive manual on this stuff)

• m4 (used by autoconf)

• autoconf

• automake

Free online tutorials:

• Using GNU Autotools

Example:

The main configure.ac used to build LibreOffice is over 12k lines of code, (but there are also 57 other configure.ac files in subfolders.)

From this my generated configure is over 41k lines of code.

And while the Makefile.in and Makefile are both only 493 lines of code. (But, there are also 768 more Makefile.in's in subfolders.)

You can use

map(lambda a : chr(a),  np.random.randint(low=65, high=90, size=4))

build gradle:

testImplementation "com.nhaarman.mockitokotlin2:mockito-kotlin:2.2.0"

code:

interface MyCallback {
  fun someMethod(value: String)
}

class MyTestableManager(private val callback: MyCallback){
  fun perform(){
    callback.someMethod("first")
    callback.someMethod("second")
    callback.someMethod("third")
  }
}

test:

import com.nhaarman.mockitokotlin2.times
import com.nhaarman.mockitokotlin2.verify
import com.nhaarman.mockitokotlin2.mock
...
val callback: MyCallback = mock()
val manager = MyTestableManager(callback)
manager.perform()

val captor: KArgumentCaptor<String> = com.nhaarman.mockitokotlin2.argumentCaptor<String>()

verify(callback, times(3)).someMethod(captor.capture())

assertTrue(captor.allValues[0] == "first")
assertTrue(captor.allValues[1] == "second")
assertTrue(captor.allValues[2] == "third")

If you already test with a submit action, you have noticed that not works too.

The reason is the form is alread posted in a $(document).read(...

So, all you need to do is change that to $(document).load(...

Now, in the moment of you browaser load the page, he will execute.

And will work ;D

As noted in the comments, there are some things to try: gc.collect (@EdChum) may clear stuff, for example. At least from my experience, these things sometimes work and often don't.

There is one thing that always works, however, because it is done at the OS, not language, level.

Suppose you have a function that creates an intermediate huge DataFrame, and returns a smaller result (which might also be a DataFrame):

def huge_intermediate_calc(something):
    ...
    huge_df = pd.DataFrame(...)
    ...
    return some_aggregate

Then if you do something like

import multiprocessing

result = multiprocessing.Pool(1).map(huge_intermediate_calc, [something_])[0]

Then the function is executed at a different process. When that process completes, the OS retakes all the resources it used. There's really nothing Python, pandas, the garbage collector, could do to stop that.

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

In Objective-C, a @synchronized block handles locking and unlocking (as well as possible exceptions) automatically for you. The runtime dynamically essentially generates an NSRecursiveLock that is associated with the object you're synchronizing on. This Apple documentation explains it in more detail. This is why you're not seeing the log messages from your NSLock subclass — the object you synchronize on can be anything, not just an NSLock.

Basically, @synchronized (...) is a convenience construct that streamlines your code. Like most simplifying abstractions, it has associated overhead (think of it as a hidden cost), and it's good to be aware of that, but raw performance is probably not the supreme goal when using such constructs anyway.

Besides what I came across here, running the following was the simplest way to dump queries to a log file without restarting

SET global log_output = 'FILE';
SET global general_log_file='/Applications/MAMP/logs/mysql_general.log';
SET global general_log = 1;

can be turned off with

SET global general_log = 0;

Don't forget to make sure that the "Reduce data usage" setting is turned OFF, as it seems to download cached data (from Google servers?) even though your local cache is flushed.

gcc -dumpversion

-dumpversion Print the compiler version (for example, 3.0) — and don't do anything else.

The same works for following compilers/aliases:

cc -dumpversion
g++ -dumpversion
clang -dumpversion
tcc -dumpversion

Be careful with automate parsing the GCC output:

• Output of --version might be localized (e.g. to Russian, Chinese, etc.)
• GCC might be built with option --with-gcc-major-version-only. And some distros (e.g. Fedora) are already using that
• GCC might be built with option --with-pkgversion. And --version output will contain something like Android (5220042 based on r346389c) clang version 8.0.7 (it's real version string)

As stated by Buffernet, you cannot use a distribution provisioning profile to debug. When I switched to a developer provisioning profile, I got the error "A Valid Provisioning Profile For This Executable Was Not Found".

A quick google for this lead me to the article listed below. From there, I realised that I hadn't got a valid development provisioning profile as my iPhone hadn't been added to the Provisioning Portal and all the other stuff involved.

Make sure you run an iPhone developer provisioning profile and your device has been added to the provisioning portal!

You can set custom fonts for every layout one by one ,with just one function call from every layout by passing its root View.First ,create a singelton approach for accessing font object like this

 public class Font {
    private static Font font;
    public Typeface ROBO_LIGHT;

    private Font() {

    }

    public static Font getInstance(Context context) {
        if (font == null) {
            font = new Font();
            font.init(context);
        }
        return font;

    }

    public void init(Context context) {

        ROBO_LIGHT = Typeface.createFromAsset(context.getAssets(),
                "Roboto-Light.ttf");
    }

}

You can define different fonts in above class, Now Define a font Helper class that will apply fonts :

   public class FontHelper {

    private static Font font;

    public static void applyFont(View parentView, Context context) {

        font = Font.getInstance(context);

        apply((ViewGroup)parentView);

    }

    private static void apply(ViewGroup parentView) {
        for (int i = 0; i < parentView.getChildCount(); i++) {

            View view = parentView.getChildAt(i);

//You can add any view element here on which you want to apply font 

            if (view instanceof EditText) {

                ((EditText) view).setTypeface(font.ROBO_LIGHT);

            }
            if (view instanceof TextView) {

                ((TextView) view).setTypeface(font.ROBO_LIGHT);

            }

            else if (view instanceof ViewGroup
                    && ((ViewGroup) view).getChildCount() > 0) {
                apply((ViewGroup) view);
            }

        }

    }

}

In the above code, I am applying fonts on textView and EditText only , you can apply fonts on other view elements as well similarly.You just need to pass the id of your root View group to the above apply font method. for example your layout is :

<RelativeLayout 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"
    android:orientation="vertical"
    android:id="@+id/mainParent"
    tools:context="${relativePackage}.${activityClass}" >

    <RelativeLayout
        android:id="@+id/mainContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/homeFooter"
        android:layout_below="@+id/edit" >

        <ImageView
            android:id="@+id/PreviewImg"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/abc_list_longpressed_holo"
            android:visibility="gone" />

        <RelativeLayout
            android:id="@+id/visibilityLayer"
            android:layout_width="match_parent"
            android:layout_height="fill_parent" >

            <ImageView
                android:id="@+id/UseCamera"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:src="@drawable/camera" />

            <TextView
                android:id="@+id/tvOR"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@+id/UseCamera"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="20dp"
                android:text="OR"
                android:textSize="30dp" />

            <TextView
                android:id="@+id/tvAND"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="20dp"
                android:text="OR"
                android:textSize="30dp" />

</RelativeLayout>

In the Above Layout the root parent id is "Main Parent " now lets apply font

public class MainActivity extends BaseFragmentActivity {

    private EditText etName;
    private EditText etPassword;
    private TextView tvTitle;
    public static boolean isHome = false;

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

       Font font=Font.getInstance(getApplicationContext());
        FontHelper.applyFont(findViewById(R.id.mainParent),          getApplicationContext());
   }    
}

Cheers :)

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

I know DOS and cmd prompt DOES NOT LIKE spaces in folder names. Your code starts with

cd c:\Program files\IIS Express

and it's trying to go to c:\Program in stead of C:\"Program Files"

Change the folder name and *.exe name. Hope this helps

Another option is to use an array, e.g. void method(SomeClass[] v) { v[0] = ...; } but 1) the array must be initialized before method invoked, 2) still one cannot implement e.g. swap method in this way... This way is used in JDK, e.g. in java.util.concurrent.atomic.AtomicMarkableReference.get(boolean[]).

Considering that both strings may be very large, there are 2 main approaches bitwise search and localeCompare

I recommed this function

function compareLargeStrings(a,b){
    if (a.length !== b.length) {
         return false;
    }
    return a.localeCompare(b) === 0;
}

I tried everything on my end and ended up with the following.

I had the first line as:

<?xmlversion="1.0"encoding="utf-8"?>

And I was missing two spaces there, and it should be:

<?xml version="1.0" encoding="utf-8"?>

Before the version and before the encoding there should be a space.

<a href="javascript:alert('Hello!');">Clicky</a>

EDIT, years later: NO! Don't ever do this! I was young and stupid!

Edit, again: A couple people have asked why you shouldn't do this. There's a couple reasons:

1. Presentation: HTML should focus on presentation. Putting JS in an HREF means that your HTML is now, kinda, dealing with business logic.

2. Security: Javascript in your HTML like that violates Content Security Policy (CSP). Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement or distribution of malware. Read more here.

3. Accessibility: Anchor tags are for linking to other documents/pages/resources. If your link doesn't go anywhere, it should be a button. This makes it a lot easier for screen readers, braille terminals, etc, to determine what's going on, and give visually impaired users useful information.

The easiest way:

Step 1: Open AndroidManifest.xml file

You can see the file here!

Step 2: Locate android:theme="@style/AppTheme" >

Step 3: Change to android:theme="@style/Theme.AppCompat.NoActionBar" >

Step 4: Then Add ImageView & Image

Step 4: That's it!

Try to declare UseHttpGet over your method.

[ScriptMethod(UseHttpGet = true)]
public string HelloWorld()
{
    return "Hello World";

Sometimes it may happen that you run multiple applications on the same java VM. In Case you have tried all the other solutions described above and it didnt work. Try Running your process by running it on a newly created java VM by passing vmargs

-agentlib:jdwp=transport=dt_socket,server=y,address=10049,suspend=n . 

Here address is what the vm takes.

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug flags.

First as a baseline, try running

$ openssl s_client -connect host:443 -state -debug

You'll get a ton of output, but the lines we are interested in look like this:

SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03                        .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A

What's happening here:

• The -state flag is responsible for displaying the end of the previous section:

  SSL_connect:SSLv3 read server done A  
  

  This is only important for helping you find your place in the output.

• Then the -debug flag is showing the raw bytes being sent in the next step:

  write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
  0000 - 16 03 01 00 07 0b 00 00-03                        .........
  000c - <SPACES/NULS>
  

• Finally, the -state flag is once again reporting the result of the step that -debug just echoed:

  SSL_connect:SSLv3 write client certificate A
  

So in other words: s_client finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.

If you repeat the test, but this time include the -cert and -key flags like this:

$ openssl s_client -connect host:443 \
   -cert cert_and_key.pem \
   -key cert_and_key.pem  \
   -state -debug

your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:

SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31   ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11-                          ..^%/lC.
SSL_connect:SSLv3 write client certificate A

The 1576 bytes is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.

If that's what you want to do, it would be better to use if statements. For example:

if(liCount == 0){
    setLayoutState('start');
}
if(liCount<=5 && liCount>0){
    setLayoutState('upload1Row');
}
if(liCount<=10 && liCount>5){
    setLayoutState('upload2Rows');
}             
var api = $('#UploadList').data('jsp');
    api.reinitialise();

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

I once had a json that had ids that needed to be incremented by one since they were 0-indexed and that was breaking Mysql auto-increment.

So for each object I wrote this code - might be helpful to someone:

public static void  incrementValue(JSONObject obj, List<String> keysToIncrementValue) {
        Set<String> keys = obj.keySet();
        for (String key : keys) {
            Object ob = obj.get(key);

            if (keysToIncrementValue.contains(key)) {
                obj.put(key, (Integer)obj.get(key) + 1);
            }

            if (ob instanceof JSONObject) {
                incrementValue((JSONObject) ob, keysToIncrementValue);
            }
            else if (ob instanceof JSONArray) {
                JSONArray arr = (JSONArray) ob;
                for (int i=0; i < arr.length(); i++) {
                    Object arrObj = arr.get(0);
                    if (arrObj instanceof JSONObject) {
                        incrementValue((JSONObject) arrObj, keysToIncrementValue);
                    }
                }
            }
        }
    }

usage:

JSONObject object = ....
incrementValue(object, Arrays.asList("id", "product_id", "category_id", "customer_id"));

this can be transformed to work for JSONArray as parent object too

Something like this would work

/^\d{2}$/

If you try joining C on a field from B before joining B, i.e.:

SELECT A.x, 
       A.y, 
       A.z 
FROM A 
   INNER JOIN C
       on B.x = C.x
   INNER JOIN B
       on A.x = B.x

your query will fail, so in this case the order matters.

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText 
        android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" 
        android:inputType="text" 
        android:maxLines="1"/>
    <ListView 
        android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">
    <EditText 
        android:id="@+id/userName" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:hint="Username"  
        android:imeOptions="actionDone" 
        android:inputType="text"
        android:maxLines="1"
       />
    <EditText 
        android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Password" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

Let's see:

• O(N) pass to find min/max allocate
• bit-array for found
• O(N) pass swapping duplicates to end.

A method group is the name for a set of methods (that might be just one) - i.e. in theory the ToString method may have multiple overloads (plus any extension methods): ToString(), ToString(string format), etc - hence ToString by itself is a "method group".

It can usually convert a method group to a (typed) delegate by using overload resolution - but not to a string etc; it doesn't make sense.

Once you add parentheses, again; overload resolution kicks in and you have unambiguously identified a method call.

I faced similar exception in my application. After looking into the stacktrace it was clear that exception was thrown within a FlushEntityEventListener class.

In Hibernate 4.3.7 the MSLocalSessionFactory bean no longer supports the eventListeners property. Hence, one has to explicitly fetch the service registry from individual Hibernate session beans and then set the required custom event listeners.

In the process of adding custom event listeners we need to make sure the corresponding default event listeners are removed from the respective Hibernate session.

If the default event listener is not removed then the case arises of two event listeners registered against same event. In this case while iterating over these listeners, against first listeners any collections in the session will be flagged as reached and while processing the same collection against second listener would throw this Hibernate exception.

So, make sure that when registering custom listeners corresponding default listeners are removed from registry.

: is the delimiter of the slice syntax to 'slice out' sub-parts in sequences , [start:end]

[1:5] is equivalent to "from 1 to 5" (5 not included)
[1:] is equivalent to "1 to end"
[len(a):] is equivalent to "from length of a to end"

Watch https://youtu.be/tKTZoB2Vjuk?t=41m40s at around 40:00 he starts explaining that.

Works with tuples and strings, too.

I have done the following on a Citrix XenDesktop VM, however you could just do this on your local PC:

Microsoft Virtual PC

If you are running Windows 7, you can download Microsoft virtual PC and create as many copies of Virtual PC as you need for testing without any licensing issues:

• http://www.microsoft.com/windows/virtual-pc/default.aspx

This requires no additional Windows licenses; you simply set up multiple machines with different browsers on them. You can run the browsers out of the window by following the tutorial available here:

• http://ieblog.members.winisp.net/images/InstallingXPMode.htm

Installing Browsers

You will need to create at least 3 virtual PC's (tip: keep the memory down to 256mb for each virtual PC to avoid wasting memory on the virtual desktops).

On the first VPC I installed this:

• http://tredosoft.com/Multiple_IE

along with Chrome 1, Safari 3.1, Opera 8.

On the second I installed Internet Explorer 7, Chrome 3, Safari 3.2.1, Opera 9.

On the third I installed Internet Explorer 8, Chrome 8. Safari 4.0.5, Opera 10.

On Windows 7 (native machine) I had Internet Explorer 9, Chrome 11, Safari 5, Opera 11 and for Firefox I install the following app natively too:

• http://utilu.com/UtiluMFC/

Personally I would not go back further than 5 years with compatibility (other than IE for government networks) unless you have a specific requirement (I split Chrome & Opera across years as I decided there were just to many releases). However, if you find that someone has a specific issue with a site using a specific version of the browser it becomes very easy to install additional virtual machines to run additional browser versions.

Obtaining Older Browsers

You can download older versions of Chrome from here:

• http://www.oldapps.com/google_chrome.php

and Opera here:

• http://www.oldapps.com/opera.php

Virtualizing The Test Platform (Optional)

I use Xen Desktop to virtualize the testing platform so that I can use it anywhere and have included my favorite development tools on there as well:

• http://deliver.citrix.com/go/citrix/XenDesktop

The express edition is available for free.

A Good Commercial Alternative

Another great product I recently came accross is Stylizer which is a CSS editor that installs multiple versions of browsers for testing purposes, however this is a commercial paid for product but is very good and worth the small fee they require to run it.

I'm running into the same issue with one of my own apps. So far I've found the only non-deprecated way to access Google News data is through their RSS feeds. They have a feed for each section and also a useful search function. However, these are only for noncommercial use.

As for viable alternatives I'll be trying out these two services: Feedzilla, Daylife

According to the spec RFC 2045 #Syntax of the Content-Type Header Field application/myappname is not allowed, but application/x-myappname is allowed and sounds most appropriate for you're application to me.

According to the HTML standard, the content model of the HTML element is:

A head element followed by a body element.

You can either define the BODY element in the source code:

<html>
    <body>
        ... web-page ...
    </body>
</html>

or you can omit the BODY element:

<html>
    ... web-page ...
</html>

However, it is invalid to place the BODY element inside the web-page content (in-between other elements or text content), like so:

<html>
    ... content ...
    <body>
        ... content ...
    </body>
    ... content ...
</html>

My guess is:

SELECT       LastName + ', ' + FirstName AS 'FullName'
FROM         customers
GROUP BY     LastName + ', ' + FirstName

Oracle has a similar limitation, which is annoying. I'm curious if there exists a better solution.

To answer the second half of the question, this limitation applies to more complex expressions such as your case statement as well. The best suggestion I've seen it to use a sub-select to name the complex expression.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Other answers have given clear enough examples of a record referencing another record in the same table.

There are even valid use cases for a record referencing itself in the same table. For example, a point of sale system accepting many tenders may need to know which tender to use for change when the payment is not the exact value of the sale. For many tenders that's the same tender, for others that's domestic cash, for yet other tenders, no form of change is allowed.

All this can be pretty elegantly represented with a single tender attribute which is a foreign key referencing the primary key of the same table, and whose values sometimes match the respective primary key of same record. In this example, the absence of value (also known as NULL value) might be needed to represent an unrelated meaning: this tender can only be used at its full value.

Popular relational database management systems support this use case smoothly.

Take-aways:

1. When inserting a record, the foreign key reference is verified to be present after the insert, rather than before the insert.

2. When inserting multiple records with a single statement, the order in which the records are inserted matters. The constraints are checked for each record separately.

3. Certain other data patterns, such as those involving circular dependences on record level going through two or more tables, cannot be purely inserted at all, or at least not with all the foreign keys enabled, and they have to be established using a combination of inserts and updates (if they are truly necessary).

For anyone that needs to set the EditText cursor color dynamically, below you will find two ways to achieve this.

First, create your cursor drawable:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="#ff000000" />

    <size android:width="1dp" />

</shape>

Set the cursor drawable resource id to the drawable you created (https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564">source)):

try {
    Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
    f.setAccessible(true);
    f.set(yourEditText, R.drawable.cursor);
} catch (Exception ignored) {
}

To just change the color of the default cursor drawable, you can use the following method:

public static void setCursorDrawableColor(EditText editText, int color) {
    try {
        Field fCursorDrawableRes = 
            TextView.class.getDeclaredField("mCursorDrawableRes");
        fCursorDrawableRes.setAccessible(true);
        int mCursorDrawableRes = fCursorDrawableRes.getInt(editText);
        Field fEditor = TextView.class.getDeclaredField("mEditor");
        fEditor.setAccessible(true);
        Object editor = fEditor.get(editText);
        Class<?> clazz = editor.getClass();
        Field fCursorDrawable = clazz.getDeclaredField("mCursorDrawable");
        fCursorDrawable.setAccessible(true);

        Drawable[] drawables = new Drawable[2];
        Resources res = editText.getContext().getResources();
        drawables[0] = res.getDrawable(mCursorDrawableRes);
        drawables[1] = res.getDrawable(mCursorDrawableRes);
        drawables[0].setColorFilter(color, PorterDuff.Mode.SRC_IN);
        drawables[1].setColorFilter(color, PorterDuff.Mode.SRC_IN);
        fCursorDrawable.set(editor, drawables);
    } catch (final Throwable ignored) {
    }
}

You can design a range method that increments a 'from' number by a desired amount until it reaches a 'to' number. This example will 'count' up or down, depending on whether from is larger or smaller than to.

Array.range= function(from, to, step){
    if(typeof from== 'number'){
        var A= [from];
        step= typeof step== 'number'? Math.abs(step):1;
        if(from> to){
            while((from -= step)>= to) A.push(from);
        }
        else{
            while((from += step)<= to) A.push(from);
        }
        return A;
    }   
}

If you ever want to step by a decimal amount : Array.range(0,1,.01) you will need to truncate the values of any floating point imprecision. Otherwise you will return numbers like 0.060000000000000005 instead of .06.

This adds a little overhead to the other version, but works correctly for integer or decimal steps.

Array.range= function(from, to, step, prec){
    if(typeof from== 'number'){
        var A= [from];
        step= typeof step== 'number'? Math.abs(step):1;
        if(!prec){
            prec= (from+step)%1? String((from+step)%1).length+1:0;
        }
        if(from> to){
            while(+(from -= step).toFixed(prec)>= to) A.push(+from.toFixed(prec));
        }
        else{
            while(+(from += step).toFixed(prec)<= to) A.push(+from.toFixed(prec));
        }
        return A;
    }   
}

You can use input type="reset"

<form action="/action_page.php">
  text: <input type="text" name="email" /><br />  
  <input type="reset" defaultValue="Reset" />  
</form>

For HSQLDB:

ALTER TABLE tableName ALTER COLUMN columnName SET NULL;

Here's how to do it from a csv:

import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import griddata

# Load data from CSV
dat = np.genfromtxt('dat.xyz', delimiter=' ',skip_header=0)
X_dat = dat[:,0]
Y_dat = dat[:,1]
Z_dat = dat[:,2]

# Convert from pandas dataframes to numpy arrays
X, Y, Z, = np.array([]), np.array([]), np.array([])
for i in range(len(X_dat)):
        X = np.append(X, X_dat[i])
        Y = np.append(Y, Y_dat[i])
        Z = np.append(Z, Z_dat[i])

# create x-y points to be used in heatmap
xi = np.linspace(X.min(), X.max(), 1000)
yi = np.linspace(Y.min(), Y.max(), 1000)

# Interpolate for plotting
zi = griddata((X, Y), Z, (xi[None,:], yi[:,None]), method='cubic')

# I control the range of my colorbar by removing data 
# outside of my range of interest
zmin = 3
zmax = 12
zi[(zi<zmin) | (zi>zmax)] = None

# Create the contour plot
CS = plt.contourf(xi, yi, zi, 15, cmap=plt.cm.rainbow,
                  vmax=zmax, vmin=zmin)
plt.colorbar()  
plt.show()

where dat.xyz is in the form

x1 y1 z1
x2 y2 z2
...

Check whether your app has the needed permissions.I was also getting the same error and I checked the logcat debug log which showed this:

04-15 13:38:25.387: E/AndroidRuntime(694): java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:555-555-5555 cmp=com.android.phone/.OutgoingCallBroadcaster } from ProcessRecord{44068640 694:rahulserver.test/10055} (pid=694, uid=10055) requires android.permission.CALL_PHONE

I then gave the needed permission in my android-manifest which worked for me.

SMH, a lot of hours wasted on this due to lack of proper documentation and not everyone uses IIS... If anyone else is still stuck on this issue I hope this helps.

Solution: Trusted Self Signed SSL CERT for localhost on Windows 10

Note: If you only need the SSL cert follow the Certification Creation section

Stack: Azure Function App(Node.js), React.js - Windows 10

Certification Creation

Step 1 - Create Certificate: OpenPowershell and run the following:

New-SelfSignedCertificate -NotBefore (Get-Date) -NotAfter (Get-Date).AddYears(5) `
-Subject "CN=localhost" -KeyAlgorithm "RSA" -KeyLength 2048 `
-HashAlgorithm "SHA256" -CertStoreLocation "Cert:\CurrentUser\My" `
-FriendlyName "HTTPS Development Certificate" `
-TextExtension @("2.5.29.19={text}","2.5.29.17={text}DNS=localhost")

Step 2 - Copy Certificate: Open Certificate Manager by pressing the windows key and search for "manage user certificates". Navigate to Personal -> Certificates and copy the localhost cert to Trusted Root Certification Authorities -> Certificates

Personal -> Certificates

Trusted Root Certification Authorities -> Certificates

(Friendly Name will be HTTPS Development Certificate)

Step 3. Export Certificate right click cert -> All Tasks -> Export which will launch the Certificate Export Wizard: Certificate Export Wizard

• Click next
• Select Yes, export the private Key Export private key
• Select the following format Personal Information Exchange - PKCS #12 and leave the first and last checkboxes selected. Export format
• Select a password; enter something simple if you like ex. "1111" Enter password
• Save file to a location you will remember ex. Desktop or Sites (you can name the file development.pfx) Save file

Step 4. Restart Chrome

Azure Function App (Server) - SSL Locally with .PFX

In this case we will run an Azure Function App with the SSL cert.

• copy the exported development.pfx file to your azure functions project root
• from cmd.exe run the following to start your functions app func start --useHttps --cert development.pfx --password 1111" (If you used a different password and filename don't forget to update the values in this script)
• Update your package.json scripts to start your functions app:

React App (Client) - Run with local SSL

Install openssl locally, this will be used to convert the development.pfx to a cert.pem and server.key. Source - Convert pfx to pem file

1. open your react app project root and create a cert folder. (project-root/cert)
2. create a copy of the development.pfx file in the cert folder. (project-root /cert/development.pfx)
3. open command prompt from the cert directory and run the following:
4. convert development.pfx to cert.pem: openssl pkcs12 -in development.pfx -out cert.pem -nodes
5. extract private key from development.pfx to key.pem: openssl pkcs12 -in development.pfx -nocerts -out key.pem
6. remove password from the extracted private key: openssl rsa -in key.pem -out server.key
7. update your .env.development.local file by adding the following lines:

SSL_CRT_FILE=cert.pem
SSL_KEY_FILE=server.key

8. start your react app npm start

Here is the direct solution:

// POST api/<controller>
[HttpPost, Route("postproducts/{product1}/{product2}")]
public void PostProducts([FromUri]Product product, Product product2)
{
    Product productOne = product; 
    Product productTwo = product2; 
}

$scope.url = 'http://localhost:53263/api/Products/' +
                 $scope.product + '/' + $scope.product2
$http.post($scope.url)
    .success(function(response) {
        alert("success") 
    })
    .error(function() { alert("fail") });
};

If you are sane you do this:

var $scope.products.product1 = product1;
var $scope.products.product2 = product2;

And then send products in the body (like a balla).

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

Check this example:

class CartridgeShell extends React.Component {_x000D_
_x000D_
   constructor(props) {_x000D_
      super(props);_x000D_
      this.state = {value:''}_x000D_
_x000D_
      this.handleChange = this.handleChange.bind(this);_x000D_
      this.keyPress = this.keyPress.bind(this);_x000D_
   } _x000D_
 _x000D_
   handleChange(e) {_x000D_
      this.setState({ value: e.target.value });_x000D_
   }_x000D_
_x000D_
   keyPress(e){_x000D_
      if(e.keyCode == 13){_x000D_
         console.log('value', e.target.value);_x000D_
         // put the login here_x000D_
      }_x000D_
   }_x000D_
_x000D_
   render(){_x000D_
      return(_x000D_
         <input value={this.state.value} onKeyDown={this.keyPress} onChange={this.handleChange} fullWidth={true} />_x000D_
      )_x000D_
    }_x000D_
}_x000D_
_x000D_

Based on my comment to the accepted answer, there are a lot potential pitfalls that you may encounter by declaring font-sizes smaller than 12px. By declaring styles that lead to computed font-sizes of less than 12px, like so:

html {
  font-size: 8px;
}
p {
  font-size: 1.4rem;
}
// Computed p size: 11px.

You'll run into issues with browsers, like Chrome with a Chinese language pack that automatically renders any font sizes computed under 12px as 12px. So, the following is true:

h6 {
    font-size: 12px;
}
p {
   font-size: 8px;
}
// Both render at 12px in Chrome with a Chinese language pack.   
// How unpleasant of a surprise.

I would also argue that for accessibility reasons, you generally shouldn't use sizes under 12px. You might be able to make a case for captions and the like, but again--prepare to be surprised under some browser setups, and prepared to make your grandma squint when she's trying to read your content.

I would instead, opt for something like this:

h1 {
    font-size: 2.5rem;
}

h2 {
    font-size: 2.25rem;
}

h3 {
    font-size: 2rem;
}

h4 {
    font-size: 1.75rem;
}

h5 {
    font-size: 1.5rem;
}

h6 {
    font-size: 1.25rem;
}

p {
    font-size: 1rem;
}

@media (max-width: 480px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 480px) {
    html {
        font-size: 13px;
    }
}

@media (min-width: 768px) {
    html {
        font-size: 14px;
    }
}

@media (min-width: 992px) {
    html {
        font-size: 15px;
    }
}

@media (min-width: 1200px) {
    html {
        font-size: 16px;
    }
}

You'll find that tons of sites that have to focus on accessibility use rather large font sizes, even for p elements.

As a side note, setting margin-bottom equal to the font-size usually also tends to be attractive, i.e.:

h1 {
    font-size: 2.5rem;
    margin-bottom: 2.5rem;
}

Good luck.

I ran into a similar problem where I have a dependency property that I wanted the class to listen to change events to grab related data from a service.

public static readonly DependencyProperty CustomerProperty = 
    DependencyProperty.Register("Customer", typeof(Customer),
        typeof(CustomerDetailView),
        new PropertyMetadata(OnCustomerChangedCallBack));

public Customer Customer {
    get { return (Customer)GetValue(CustomerProperty); }
    set { SetValue(CustomerProperty, value); }
}

private static void OnCustomerChangedCallBack(
        DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
    CustomerDetailView c = sender as CustomerDetailView;
    if (c != null) {
        c.OnCustomerChanged();
    }
}

protected virtual void OnCustomerChanged() {
    // Grab related data.
    // Raises INotifyPropertyChanged.PropertyChanged
    OnPropertyChanged("Customer");
}

In Debian Linux wget can be configured to use a proxy both via environment variables and via wgetrc. In both cases the variable names to be used for HTTP and HTTPS connections are

http_proxy=hostname_or_IP:portNumber
https_proxy=hostname_or_IP:portNumber

Note that the file /etc/wgetrc takes precedence over the environment variables, hence if your system has a proxy configured there and you try to use the environment variables, they would seem to have no effect!

I had to split a list for feature extraction in two parts lt,lc:

ltexts = ((df4.ix[0:,[3,7]]).values).tolist()
random.shuffle(ltexts)

featsets = [(act_features((lt)),lc) 
              for lc, lt in ltexts]

def act_features(atext):
  features = {}
  for word in nltk.word_tokenize(atext):
     features['cont({})'.format(word.lower())]=True
  return features

The algo will need to work on the following model,

• keep track of the head
• Recurse till end of linklist
• Reverse linkage

Structure:

Head    
|    
1-->2-->3-->4-->N-->null

null-->1-->2-->3-->4-->N<--null

null-->1-->2-->3-->4<--N<--null

null-->1-->2-->3<--4<--N<--null

null-->1-->2<--3<--4<--N<--null

null-->1<--2<--3<--4<--N<--null

null<--1<--2<--3<--4<--N
                       |
                       Head

Code:

public ListNode reverse(ListNode toBeNextNode, ListNode currentNode)
{               
        ListNode currentHead = currentNode; // keep track of the head

        if ((currentNode==null ||currentNode.next==null )&& toBeNextNode ==null)return currentHead; // ignore for size 0 & 1

        if (currentNode.next!=null)currentHead = reverse(currentNode, currentNode.next); // travarse till end recursively

        currentNode.next = toBeNextNode; // reverse link

        return currentHead;
}

Output:

head-->12345

head-->54321

I faced this issue and it get resolved by following steps.

1. Open Eclipse.ini file in Notepad
2. Search vm

3. Delete non existing JRE path from this file as mention in below

   -vm C:/Program Files/Java/jre1.8.0_181/bin

4. Save this file and run eclipse again.

you can use also this way to write css for placeholder

input::placeholder{
   text-align: center;
}

This should do the trick!

google.maps.event.trigger(map, "resize");
map.panTo(marker.getPosition());
map.setZoom(14);

You will need to have your maps global

Another crucial method not mentioned here is using the same TCP connection for multiple HTTP requests, and exactly one curl command for this.

This is very useful to save network bandwidth, client and server resources, and overall the need of using multiple curl commands, as curl by default closes the connection when end of command is reached.

Keeping the connection open and reusing it is very common for standard clients running a web-app.

Starting curl version 7.36.0, the --next or -: command-line option allows to chain multiple requests, and usable both in command-line and scripting.

For example:

• Sending multiple requests on the same TCP connection:

curl http://example.com/?update_=1 -: http://example.com/foo

• Sending multiple different HTTP requests on the same connection:

curl http://example.com/?update_=1 -: -d "I am posting this string" http://example.com/?update_=2

• Sending multiple HTTP requests with different curl options for each request:

curl -o 'my_output_file' http://example.com/?update_=1 -: -d "my_data" -s -m 10 http://example.com/foo -: -o /dev/null http://example.com/random

From the curl manpage:

-:, --next

Tells curl to use a separate operation for the following URL and associated options. This allows you to send several URL requests, each with their own specific options, for example, such as different user names or custom requests for each.

-:, --next will reset all local options and only global ones will have their values survive over to the operation following the -:, --next instruction. Global options include -v, --verbose, --trace, --trace-ascii and --fail-early.

For example, you can do both a GET and a POST in a single command line:

curl www1.example.com --next -d postthis www2.example.com

Added in 7.36.0.

Given the, most than probable similarities in performance, use whatever feel more correct and readable to the piece of code you're using.

I feel an operation that describes an addition, being the presence of the key already a really rare exception is best represented with the add. Semantically it makes more sense.

The dict[key] = value represents better a substitution. If I see that code I half expect the key to already be in the dictionary anyway.

If you use toFixed(n) where n > 0, a more simple and stable (no more float operations) solution can be:

(+n).toFixed(2).replace(/(\.0+|0+)$/, '')


// 0 => 0
// 0.1234 => 0.12
// 0.1001 => 0.1

// 1 => 1
// 1.1234 => 1.12
// 1.1001 => 1.1

// 100 => 100
// 100.1234 => 100.12
// 100.1001 => 100.1

PS: if you use toFixed(0), then no replace is needed.

You must use Eclipse WTP (Web Tool Platform), and should use the lastest version is Luna 4.4. Link download: Eclipse IDE for Java EE Developers http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/lunar

The message from Linus Torvalds may answer your question:

Modify/edit old commit messages

Short answer: you can not (if pushed).

extract (Linus refers to BitKeeper as BK):

Side note, just out of historical interest: in BK you could.

And if you're used to it (like I was) it was really quite practical. I would apply a patch-bomb from Andrew, notice something was wrong, and just edit it before pushing it out.

I could have done the same with git. It would have been easy enough to make just the commit message not be part of the name, and still guarantee that the history was untouched, and allow the "fix up comments later" thing.

But I didn't.

Part of it is purely "internal consistency". Git is simply a cleaner system thanks to everything being SHA1-protected, and all objects being treated the same, regardless of object type. Yeah, there are four different kinds of objects, and they are all really different, and they can't be used in the same way, but at the same time, even if their encoding might be different on disk, conceptually they all work exactly the same.

But internal consistency isn't really an excuse for being inflexible, and clearly it would be very flexible if we could just fix up mistakes after they happen. So that's not a really strong argument.

The real reason git doesn't allow you to change the commit message ends up being very simple: that way, you can trust the messages. If you allowed people to change them afterwards, the messages are inherently not very trustworthy.

To be complete, you could rewrite your local commit history in order to reflect what you want, as suggested by sykora (with some rebase and reset --hard, gasp!)

However, once you publish your revised history again (with a git push origin +master:master, the + sign forcing the push to occur, even if it doesn't result in a "fast-forward" commit)... you might get into some trouble.

Extract from this other SO question:

I actually once pushed with --force to git.git repository and got scolded by Linus BIG TIME. It will create a lot of problems for other people. A simple answer is "don't do it".

It works for me...

 <input id="relacionac" name="relacionac" type="number" min="0.4" max="0.7" placeholder="0,40-0,70" class="form-control input-md" step="0.01">

then, I define min in 0.4 and max in 0.7 with step 0.01: 0.4, 0.41, 0,42 ... 0.7

On bash at least, we can force the return value of the exit code of the command to be 0

You can remove the old remote and add it again

git remote remove $1 || true
git remote add $1 $2

1. insert into mytable(id, myblob) values (1,EMPTY_BLOB);
2. SELECT * FROM mytable mt where mt.id=1 for update
3. Click on the Lock icon to unlock for editing
4. Click on the ... next to the BLOB to edit
5. Select the appropriate tab and click open on the top left.
6. Click OK and commit the changes.

EDIT: Starting from IPython 3 (now Jupyter project), the notebook has a text editor that can be used as a more convenient alternative to load/edit/save text files.

A text file can be loaded in a notebook cell with the magic command %load.

If you execute a cell containing:

%load filename.py

the content of filename.py will be loaded in the next cell. You can edit and execute it as usual.

To save the cell content back into a file add the cell-magic %%writefile filename.py at the beginning of the cell and run it. Beware that if a file with the same name already exists it will be silently overwritten.

To see the help for any magic command add a ?: like %load? or %%writefile?.

For general help on magic functions type "%magic" For a list of the available magic functions, use %lsmagic. For a description of any of them, type %magic_name?, e.g. '%cd?'.

See also: Magic functions from the official IPython docs.

If your table view is in editing mode (eg. [tableView setEditing:YES animated:NO];), you need to set tableView.allowsSelectionDuringEditing = YES;

1. The .git at the end of the repository name is just a convention. Typically, on git servers repositories are kept in directories named project.git. The git client and protocol honours this convention by testing for project.git when only project is specified.

2. git://[email protected]/peter/first_app.git is not a valid git url. git repositories can be identified and accessed via various url schemes specified here. [email protected]:peter/first_app.git is the ssh url mentioned on that page.

3. git is flexible. It allows you to track your local branch against almost any branch of any repository. While master (your local default branch) tracking origin/master (the remote default branch) is a popular situation, it is not universal. Many a times you may not want to do that. This is why the first git push is so verbose. It tells git what to do with the local master branch when you do a git pull or a git push.

4. The default for git push and git pull is to work with the current branch's remote. This is a better default than origin master. The way git push determines this is explained here.

git is fairly elegant and comprehensible but there is a learning curve to walk through.

The classical way to achieve this is to put the text into the div and use an image replacement technique.

<div class"ir background-image">Your alt text</div>

with background-image beeing the class where you assign the background image and ir could be HTML5boilerplates image replacement class, below:

/* ==========================================================================
   Helper classes
   ========================================================================== */

/*
 * Image replacement
 */

.ir {
    background-color: transparent;
    border: 0;
    overflow: hidden;
    /* IE 6/7 fallback */
    *text-indent: -9999px;
}

.ir:before {
    content: "";
    display: block;
    width: 0;
    height: 150%;
}

To change use of class instead of ID

<script type="text/javascript"> 
    $(function() { 
        $('.my_date1').datepicker(); 
        $('.my_date2').datepicker(); 
        $('.my_date3').datepicker(); 
        ... 
    }); 
</script>

I have a search form with an icon that clears the text when clicked. However, the problem (on mobile & tablets) was that the keyboard would collapse/hide, as the click event removed focus was removed from the input.

Goal: after clearing the search form (clicking/tapping on x-icon) keep the keyboard visible!

To accomplish this, apply stopPropagation() on the event like so:

function clear ($event) {
    $event.preventDefault();
    $event.stopPropagation();
    self.query = '';
    $timeout(function () {
        document.getElementById('sidebar-search').focus();
    }, 1);
}

And the HTML form:

<form ng-controller="SearchController as search"
    ng-submit="search.submit($event)">
        <input type="search" id="sidebar-search" 
            ng-model="search.query">
                <span class="glyphicon glyphicon-remove-circle"
                    ng-click="search.clear($event)">
                </span>
</form>

When you say "called" I'm going to assume you mean an ID tag.

To make it cross-brower, I wouldn't suggest using the CSS3 [], although it is an option. This being said, give each of your textboxes a class like "tb" and the radio button "rb".

Then:

#divContainer .tb { width: 150px }
#divContainer .rb { width: 20px }

This assumes you are using the same classes elsewhere, if not, this will suffice:

.tb { width: 150px }
.rb { width: 20px }

As @David mentioned, to access anything within the division itself:

#divContainer [element] { ... }

Where [element] is whatever HTML element you need.

Here is a class I use when writing services. I usually have an interactive screen that comes up when the service is not called. From there I use the class as needed. It allows for multiple named instances on the same machine -hence the InstanceID field

Sample Call

  IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
  Inst.Install("MySvc", "My Sample Service", "Service that executes something",
                    _InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService,      // this is more secure, but only available in XP and above and WS-2003 and above
  System.ServiceProcess.ServiceAccount.LocalSystem,       // this is required for WS-2000
  System.ServiceProcess.ServiceStartMode.Automatic);
  if (controller == null)
  {
    controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
                }
                if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                {
                    Start_Stop.Text = "Stop Service";
                    Start_Stop_Debugging.Enabled = false;
                }
                else
                {
                    Start_Stop.Text = "Start Service";
                    Start_Stop_Debugging.Enabled = true;
                }

You Need to change your code as below:-

<html>
<body>
<div>
<form align="center" method=post>
    <input id="mainText" type="text" align="center"placeholder="Search">

    <input type="submit" onclick="myFunction()" style="position: absolute; left: 450px"/>
</form>
</div>
<script>
function myFunction(){
    $a= document.getElementById("mainText").value;
    alert($a);
        }
</script>
</body>
</html>

French translations:

$('#my_table').DataTable({
  "language": {
    "sProcessing": "Traitement en cours ...",
    "sLengthMenu": "Afficher _MENU_ lignes",
    "sZeroRecords": "Aucun résultat trouvé",
    "sEmptyTable": "Aucune donnée disponible",

OP's code is incorrect for the following reasons:

• The swaps are being performed on a nibble (4-bit) boundary, instead of a byte (8-bit) boundary.
• The shift-left << operations of the final four swaps are incorrect, they should be shift-right >> operations and their shift values would also need to be corrected.
• The use of intermediary storage is unnecessary, and the code can therefore be rewritten to be more concise/recognizable. In doing so, some compilers will be able to better-optimize the code by recognizing the oft-used pattern.

Consider the following code, which efficiently converts an unsigned value:

// Swap endian (big to little) or (little to big)
uint32_t num = 0x12345678;
uint32_t res =
    ((num & 0x000000FF) << 24) |
    ((num & 0x0000FF00) << 8) |
    ((num & 0x00FF0000) >> 8) |
    ((num & 0xFF000000) >> 24);

printf("%0x\n", res);

The result is represented here in both binary and hex, notice how the bytes have swapped:

?0111 1000 0101 0110 0011 0100 0001 0010?

Optimizing

In terms of performance, leave it to the compiler to optimize your code when possible. You should avoid unnecessary data structures like arrays for simple algorithms like this, doing so will usually cause different instruction behavior such as accessing RAM instead of using CPU registers.

It should be document.getElementById("hidden").style.display = "block"; not document.getElementById["hidden"].style.display = "block";

EDIT due to author edit:

Why are you using a <div> here? Just add an ID to the table element and add a hidden style to it. E.g. <td id="hidden" style="display:none" class="depot_table_left">

Easy way to handle onBackPressed() in Fragments

Step 1: Create a static boolean in activity.

public static Fragment_one;

Step 2: On MainActivity(Activity that holds fragment) in On Create method, declare

Fragment_one=true;

Step 3: Override onBackPressed() in MainActivity

@Override
public void onBackPressed() {

    if(Fragment_one) {
     //Back key pressed on fragment one

    }else {
      //Back key pressed on fragment two
    }
}

Step 4: On fragment_one onCreateView method declare

MainActivity.Fragment_one=true;

Step 5 On fragment_two onCreateView method declare

MainActivity.Fragment_one=false;

Note: This method can be only applicable to TWO fragments.

Adding on to @Rob Hruska's sol, this setting in server.xml inside section works:

<Context path="" docBase="gateway" reloadable="true" override="true"> </Context>

Note: override="true" might be required in some cases.

Use executeUpdate() to issue data manipulation statements. executeQuery() is only meant for SELECT queries (i.e. queries that return a result set).

Try this to avoid to_char limitations:

SELECT 
regexp_replace(regexp_replace(n,'^-\'||s,'-0'||s),'^\'||s,'0'||s)
FROM (SELECT -0.89 n,RTrim(1/2,5) s FROM dual);

If you want to fully protect your app from decompilation, look at Aladdin's Hasp. You can wrap your assemblies in an encrypted shell that can only be accessed by your application. Of course one wonders how they're able to do this but it works. I don't know however if they protect your app from runtime attachment/reflection which is what Crack.NET is able to do.

-- Edit Also be careful of compiling to native code as a solution...there are decompilers for native code as well.

If you referring to ASP.Net callbacks:

In the default model for ASP.NET Web pages, the user interacts with a page and clicks a button or performs some other action that results in a postback. The page and its controls are re-created, the page code runs on the server, and a new version of the page is rendered to the browser. However, in some situations, it is useful to run server code from the client without performing a postback. If the client script in the page is maintaining some state information (for example, local variable values), posting the page and getting a new copy of it destroys that state. Additionally, page postbacks introduce processing overhead that can decrease performance and force the user to wait for the page to be processed and re-created.

To avoid losing client state and not incur the processing overhead of a server roundtrip, you can code an ASP.NET Web page so that it can perform client callbacks. In a client callback, a client-script function sends a request to an ASP.NET Web page. The Web page runs a modified version of its normal life cycle. The page is initiated and its controls and other members are created, and then a specially marked method is invoked. The method performs the processing that you have coded and then returns a value to the browser that can be read by another client script function. Throughout this process, the page is live in the browser.

Source: http://msdn.microsoft.com/en-us/library/ms178208.aspx

If you are referring to callbacks in code:

Callbacks are often delegates to methods that are called when the specific operation has completed or performs a sub-action. You'll often find them in asynchronous operations. It is a programming principle that you can find in almost every coding language.

More info here: http://msdn.microsoft.com/en-us/library/ms173172.aspx

As for the page, I'm working on a higher order component that uses basically the above methods to do exactly this. It actually takes just a bit of time when you get down to the subtleties like initial layout and content changes. I won't claim to have done it 'correctly', but in some sense I'd consider the correct answer to use component that does this carefully and consistently.

See: react-native-paged-scroll-view. Would love feedback, even if it's that I've done it all wrong!

Consider using a package to automatically generate inline styles from your css files. A good one is Grunt Critical or Critical css for Laravel.

There is one example where in actually kills your performance.

If you use in on a O(1) container that only implements __getitem__ and has_key() but not __contains__ you will turn an O(1) search into an O(N) search (as in falls back to a linear search via __getitem__).

Fix is obviously trivial:

def __contains__(self, x):
    return self.has_key(x)

<script type="text/javascript">
function showDiv(toggle){
document.getElementById(toggle).style.display = 'block';
}
</script>

<input type="button" name="answer" onclick="showDiv('toggle')">Show</input>

<div id="toggle" style="display:none">Hello</div>

I would do something like this:

HTML:

<div class="wrapper">
    <div class="side">sidebar here</div>
    <div class="main">
        <textarea class="taclass"></textarea>
    </div>
</div><!--/ wrapper -->

CSS:

.wrapper{
    display: block;
    width: 100%;
    overflow: hidden;
}
.side{
    float:left;
    width:20%;
}
.main{
    float:right;
    width:80%;
}
.taclass{
    display:block;
    width:100%;
    padding:2%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}

SELECT sql FROM sqlite_master
WHERE tbl_name = 'table_name' AND type = 'table'

Then parse this value with Reg Exp (it's easy) which could looks similar to this: [(.*?)]

Alternatively you can use:

PRAGMA table_info(table_name)

You should be using posts with proper expires and caching headers.

I had the same problem. This work fine for me:

str(objdata).encode('utf-8')

please use this code for input text

$('#search').on("input",function (e) {});

if you use .on("change",function (e) {}); then you need to blur input

if you use .on("keyup",function (e) {}); then you get value before the last character you typed

Open a cmd shell,

cd \\
dir javaw.exe /s

In my Firefox this trick works:

function SetPixel(canvas, x, y)
{
  canvas.beginPath();
  canvas.moveTo(x, y);
  canvas.lineTo(x+0.4, y+0.4);
  canvas.stroke();
}

Small offset is not visible on screen, but forces rendering engine to actually draw a point.

package com;
import java.io.File;
public class Delete {
    public static void main(String[] args) {

        String files; 
        File file = new File("D:\\del\\yc\\gh");
        File[] listOfFiles = file.listFiles(); 
        for (int i = 0; i < listOfFiles.length; i++) 
        {
            if (listOfFiles[i].isFile()) 
            {
                files = listOfFiles[i].getName();
                System.out.println(files);
                if(!files.equalsIgnoreCase("Scan.pdf"))
                {
                    boolean issuccess=new File(listOfFiles[i].toString()).delete();
                    System.err.println("Deletion Success "+issuccess);
                }
            }
        }
    }
}

If you want to delete all files remove

if(!files.equalsIgnoreCase("Scan.pdf"))

statement it will work.

Your HTML file is not going to interact with C# directly, but you can write some C# to behave as if it were the HTML file.

For example: there is a class called System.Net.WebClient with simple methods:

using System.Net;
using System.Collections.Specialized;

...
using(WebClient client = new WebClient()) {

    NameValueCollection vals = new NameValueCollection();
    vals.Add("test", "test string");
    client.UploadValues("http://www.someurl.com/page.php", vals);
}

I'm using CentOS 7 with virtualmin and three PHP versions. I also have REMI repo enabled. it worked for me:

Step 1:

Just append PHP major version number like this php{version number}-xml. And run yum install

yum install php70-php-xml
yum install php71-php-xml
yum install php72-php-xml

Step 2:

Don't forget to restart Apache:

service httpd restart

This is basically a "some (but not all)" functionality (when contrasted with the any() and all() builtin functions).

This implies that there should be Falses and Trues among the results. Therefore, you can do the following:

some = lambda ii: frozenset(bool(i) for i in ii).issuperset((True, False))

# one way to test this is...
test = lambda iterable: (any(iterable) and (not all(iterable))) # see also http://stackoverflow.com/a/16522290/541412

# Some test cases...
assert(some(()) == False)       # all() is true, and any() is false
assert(some((False,)) == False) # any() is false
assert(some((True,)) == False)  # any() and all() are true

assert(some((False,False)) == False)
assert(some((True,True)) == False)
assert(some((True,False)) == True)
assert(some((False,True)) == True)

One advantage of this code is that you only need to iterate once through the resulting (booleans) items.

One disadvantage is that all these truth-expressions are always evaluated, and do not do short-circuiting like the or/and operators.

Five years later (I hope this developer isn't still waiting for a fix to this..)

I had the same issue, caused by the same error: I was declaring the SmtpClient inside the loop.

The fix is simple - declare it once, outside the loop...

MailAddress mail = null;
SmtpClient client = new SmtpClient();
client.Port = 25;
client.EnableSsl = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = true;
client.Host = smtpAddress;       //  Enter your company's email server here!

for(int i = 0; i < number ; i++)
{
    mail = new MailMessage(iMail.from, iMail.to);
    mail.Subject = iMail.sub;
    mail.Body = iMail.body;
    mail.IsBodyHtml = true;
    mail.Priority = MailPriority.Normal;
    mail.Sender = from;
    client.Send(mail);
}
mail.Dispose();
client.Dispose();

Trying to explain this doubt with simple diagrams.

Read Committed: Here in this isolation level, Transaction T1 will be reading the updated value of the X committed by Transaction T2.

Repeatable Read: In this isolation level, Transaction T1 will not consider the changes committed by the Transaction T2.

For some people, this will work:

You could simply add the following command into System → Preferences → Startup Applications:

bash /full/path/to/your/script.sh

There are two ways to use void:

void foo(void);

or

void *bar(void*);

The first indicates that no argument is being passed or that no argument is being returned.

The second tells the compiler that there is no type associated with the data effectively meaning that the you can't make use of the data pointed to until it is cast to a known type.

For example you will see void* used a lot when you have an interface which calls a function whose parameters can't be known ahead of time.

For example, in the Linux Kernel when deferring work you will setup a function to be run at a latter time by giving it a pointer to the function to be run and a pointer to the data to be passed to the function:

struct _deferred_work {
sruct list_head mylist;
.worker_func = bar;
.data        = somedata;
} deferred_work;

Then a kernel thread goes over a list of deferred work and when it get's to this node it effectively executes:

bar(somedata);

Then in bar you have:

void bar(void* mydata) {
    int *data = mydata;
    /* do something with data */;
}
