For JDK 1.3 or earlier :

-Xnoagent -Djava.compiler=NONE -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For JDK 1.4

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6006

For newer JDK :

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=6006

Please change the port number based on your needs.

From java technotes

From 5.0 onwards the -agentlib:jdwp option is used to load and specify options to the JDWP agent. For releases prior to 5.0, the -Xdebug and -Xrunjdwp options are used (the 5.0 implementation also supports the -Xdebug and -Xrunjdwp options but the newer -agentlib:jdwp option is preferable as the JDWP agent in 5.0 uses the JVM TI interface to the VM rather than the older JVMDI interface)

One more thing to note, from JVM Tool interface documentation:

JVM TI was introduced at JDK 5.0. JVM TI replaces the Java Virtual Machine Profiler Interface (JVMPI) and the Java Virtual Machine Debug Interface (JVMDI) which, as of JDK 6, are no longer provided.

Thanks to sud007 for this answer. In my case, I only need this part of the solution:

In CMD/Terminal:

$ adb kill-server

$ adb tcpip 5555
restarting in TCP mode port: 5555

$ adb connect 192.168.XXX.XXX

This bug brings more errors than unable to connect to 192.168.XXX.XXX:5555: Connection refused. In my case, I could connect to the device, but when you try to run the app. AndroidStudio stay in Installing APK forever. In this case, I needed to restart the phone too.

Consider the following two-dimensional list:

original = [[1, 2],
            [3, 4]]

Lets break it down step by step:

>>> original[::-1]   # elements of original are reversed
[[3, 4], [1, 2]]

This list is passed into zip() using argument unpacking, so the zip call ends up being the equivalent of this:

zip([3, 4],
    [1, 2])
#    ^  ^----column 2
#    |-------column 1
# returns [(3, 1), (4, 2)], which is a original rotated clockwise

Hopefully the comments make it clear what zip does, it will group elements from each input iterable based on index, or in other words it groups the columns.

I would advise, it is slightly better practise to use string model references for ForeignKey relationships if utilising an app based approach to seperation of logical concerns .

So, expanding on Martijn Pieters' answer:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        'app_label.Anniversary', on_delete=models.CASCADE)
    address = models.ForeignKey(
        'app_label.Address', on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

This is not possible the way you are trying it. The Jackson unmarshalling works on the compiled java code after type erasure. So your

public @ResponseBody ModelMap setTest(@RequestBody List<TestS> refunds, ModelMap map) 

is really only

public @ResponseBody ModelMap setTest(@RequestBody List refunds, ModelMap map) 

(no generics in the list arg).

The default type Jackson creates when unmarshalling a List is a LinkedHashMap.

As mentioned by @Saint you can circumvent this by creating your own type for the list like so:

class TestSList extends ArrayList<TestS> { }

and then modifying your controller signature to

public @ResponseBody ModelMap setTest(@RequestBody TestSList refunds, ModelMap map) {

As of NuGet 2.8, there is a feature to downgrade a package.

NuGet 2.8 Release Notes

Example:

The following command entered into the Package Manager Console will downgrade the Couchbase client to version 1.3.1.0.

Update-Package CouchbaseNetClient -Version 1.3.1.0

Result:

Updating 'CouchbaseNetClient' from version '1.3.3' to '1.3.1.0' in project [project name].
Removing 'CouchbaseNetClient 1.3.3' from [project name].
Successfully removed 'CouchbaseNetClient 1.3.3' from [project name].

Something to note as per crimbo below:

This approach doesn't work for downgrading from one prerelease version to other prerelease version - it only works for downgrading to a release version

This obviously is deficiency of the API design. In the first place, Activity Context and Application context are totally different objects, so the method parameters where context is used should use ApplicationContext or Activity directly, instead of using parent class Context. In the second place, the doc should specify which context to use or not explicitly.

Whilst there is no portable #define or something to rely upon, platforms do provide standard functions for converting to and from your 'host' endian.

Generally, you do storage - to disk, or network - using 'network endian', which is BIG endian, and local computation using host endian (which on x86 is LITTLE endian). You use htons() and ntohs() and friends to convert between the two.

Have you tried not setting the responseType and just type casting the response?

This is what worked for me:

/**
 * Client for consuming recordings HTTP API endpoint.
 */
@Injectable({
  providedIn: 'root'
})
export class DownloadUrlClientService {
  private _log = Log.create('DownloadUrlClientService');


  constructor(
    private _http: HttpClient,
  ) {}

  private async _getUrl(url: string): Promise<string> {
    const httpOptions = {headers: new HttpHeaders({'auth': 'false'})};
    // const httpOptions = {headers: new HttpHeaders({'auth': 'false'}), responseType: 'text'};
    const res = await (this._http.get(url, httpOptions) as Observable<string>).toPromise();
    // const res = await (this._http.get(url, httpOptions)).toPromise();
    return res;
  }
}

The warning comes from the fact that you're dereferencing src in the assignment. The expression *src has type char, which is an integral type. The expression "anotherstring" has type char [14], which in this particular context is implicitly converted to type char *, and its value is the address of the first character in the array. So, you wind up trying to assign a pointer value to an integral type, hence the warning. Drop the * from *src, and it should work as expected:

src = "anotherstring";

since the type of src is char *.

Ruby 2.1.0 introduced a to_h method on Array that does what you require if your original array consists of arrays of key-value pairs: http://www.ruby-doc.org/core-2.1.0/Array.html#method-i-to_h.

[[:foo, :bar], [1, 2]].to_h
# => {:foo => :bar, 1 => 2}

Maybe you could try

List<Article> findAllByPublicationDate(Date publicationDate);

The detail could be checked in this article:

https://www.baeldung.com/spring-data-jpa-query-by-date

You can also try this:

select MONTH(NOW())-MONTH(table_date) as 'Total Month Difference' from table_name;

OR

select MONTH(Newer_date)-MONTH(Older_date) as 'Total Month Difference' from table_Name;

Yes, this can be done via javascript feature detection ( or browser detection , e.g. Modernizr ) . Then, use yepnope.js to load required resources ( JS and/or CSS )

Use DateTime.AddDays() method with value of -1

var yesterday = DateTime.Today.AddDays(-1);

That will give you : {6/28/2012 12:00:00 AM}

You can also use

DateTime.Now.AddDays(-1)

That will give you previous date with the current time e.g. {6/28/2012 10:30:32 AM}

~ FOR VISUAL STUDIO 6 ~

use: ctrl+shift+8 to toggle on/off.

(or manualy go to: Edit> Advance > "View Whitespaces")

goodluck!

Works also for Visual Studio 2008, when Tools/Options/Environment/Keyboard/Mapping Scheme: Visual C++ 6 is selected.

Why not just simplify it to if($_GET['id']). It will return true or false depending on status of the parameter's existence.

=if(b2 = "", "", b2)

This worked for me

Create the environment with virtualenv --system-site-packages . Then, activate the virtualenv and when you want things installed in the virtualenv rather than the system python, use pip install --ignore-installed or pip install -I . That way pip will install what you've requested locally even though a system-wide version exists. Your python interpreter will look first in the virtualenv's package directory, so those packages should shadow the global ones.

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

You don't need to input form data to make SQL injection.

No one pointed this out before so through I might alert some of you.

Mostly we will try to patch forms input. But this is not the only place where you can get attacked with SQL injection. You can do very simple attack with URL which send data through GET request; Consider the fallowing example:

<a href="/show?id=1">show something</a>

Your url would look http://yoursite.com/show?id=1

Now someone could try something like this

http://yoursite.com/show?id=1;TRUNCATE table_name

Try to replace table_name with the real table name. If he get your table name right they would empty your table! (It is very easy to brut force this URL with simple script)

Your query would look something like this...

"SELECT * FROM page WHERE id = 4;TRUNCATE page"

Example of PHP vulnerable code using PDO:

<?php
...
$id = $_GET['id'];

$pdo = new PDO($database_dsn, $database_user, $database_pass);
$query = "SELECT * FROM page WHERE id = {$id}";
$stmt = $pdo->query($query);
$data = $stmt->fetch(); 
/************* You have lost your data!!! :( *************/
...

Solution - use PDO prepare() & bindParam() methods:

<?php
...
$id = $_GET['id'];

$query = 'SELECT * FROM page WHERE id = :idVal';
$stmt = $pdo->prepare($query);
$stmt->bindParam('idVal', $id, PDO::PARAM_INT);
$stmt->execute();
$data = $stmt->fetch();
/************* Your data is safe! :) *************/
...

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

It seems to me you could split the cookie key-value pairs into an array and base your search on that:

var obligations = getCookieData("obligations");

Which runs the following:

function getCookieData( name ) {
    var pairs = document.cookie.split("; "),
        count = pairs.length, parts; 
    while ( count-- ) {
        parts = pairs[count].split("=");
        if ( parts[0] === name )
            return parts[1];
    }
    return false;
}

Fiddle: http://jsfiddle.net/qFmPc/

Or possibly even the following:

function getCookieData( name ) {
    var patrn = new RegExp( "^" + name + "=(.*?);" ),
        patr2 = new RegExp( " " + name + "=(.*?);" );
    if ( match = (document.cookie.match(patrn) || document.cookie.match(patr2)) )
        return match[1];

I used an approach similar to the one taken by Josh Fraser, which determines the browser time offset from UTC and whether it recognizes DST or not (but somewhat simplified from his code):

var ClientTZ = {
    UTCoffset:  0,          // Browser time offset from UTC in minutes
    UTCoffsetT: '+0000S',   // Browser time offset from UTC in '±hhmmD' form
    hasDST:     false,      // Browser time observes DST

    // Determine browser's timezone and DST
    getBrowserTZ: function () {
        var self = ClientTZ;

        // Determine UTC time offset
        var now = new Date();
        var date1 = new Date(now.getFullYear(), 1-1, 1, 0, 0, 0, 0);    // Jan
        var diff1 = -date1.getTimezoneOffset();
        self.UTCoffset = diff1;

        // Determine DST use
        var date2 = new Date(now.getFullYear(), 6-1, 1, 0, 0, 0, 0);    // Jun
        var diff2 = -date2.getTimezoneOffset();
        if (diff1 != diff2) {
            self.hasDST = true;
            if (diff1 - diff2 >= 0)
                self.UTCoffset = diff2;     // East of GMT
        }

        // Convert UTC offset to ±hhmmD form
        diff2 = (diff1 < 0 ? -diff1 : diff1) / 60;
        var hr = Math.floor(diff2);
        var min = diff2 - hr;
        diff2 = hr * 100 + min * 60;
        self.UTCoffsetT = (diff1 < 0 ? '-' : '+') + (hr < 10 ? '0' : '') + diff2.toString() + (self.hasDST ? 'D' : 'S');

        return self.UTCoffset;
    }
};

// Onload
ClientTZ.getBrowserTZ();

Upon loading, the ClientTZ.getBrowserTZ() function is executed, which sets:

• ClientTZ.UTCoffset to the browser time offset from UTC in minutes (e.g., CST is -360 minutes, which is -6.0 hours from UTC);
• ClientTZ.UTCoffsetT to the offset in the form '±hhmmD' (e.g., '-0600D'), where the suffix is D for DST and S for standard (non-DST);
• ClientTZ.hasDST (to true or false).

The ClientTZ.UTCoffset is provided in minutes instead of hours, because some timezones have fractional hourly offsets (e.g., +0415).

The intent behind ClientTZ.UTCoffsetT is to use it as a key into a table of timezones (not provided here), such as for a drop-down <select> list.

In Swift:

 func pathForResource(  name: String?, 
                        ofType ext: String?, 
                        inDirectory subpath: String?) -> String?  {

  // **name:** Name of Hmtl
  // **ofType ext:** extension for type of file. In this case "html"
  // **inDirectory subpath:** the folder where are the file. 
  //    In this case the file is in root folder

    let path = NSBundle.mainBundle().pathForResource(             "dados",
                                                     ofType:      "html", 
                                                     inDirectory: "root")
    var requestURL = NSURL(string:path!)
    var request = NSURLRequest(URL:requestURL)

    webView.loadRequest(request)
}

You can use the following command to update the DATA PUMP DIRECTORY path,

create or replace directory DATA_PUMP_DIR as '/u01/app/oracle/admin/MYDB/dpdump/';

For me data path correction was required as I have restored the my database from production to test environment.

Same command can be used to create a new DATA PUMP DIRECTORY name and path.

In 2020 Dec, the fix did finally worked for me was restarting my mac.

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

Simple solution:

document.getElementById("upload-files").value = "";

Trying to give a very simplified explanation

Virtual Memory is divided into kernel space and the user space. Kernel space is that area of virtual memory where kernel processes will run and user space is that area of virtual memory where user processes will be running.

This division is required for memory access protections.

Whenever a bootloader starts a kernel after loading it to a location in RAM, (on an ARM based controller typically)it needs to make sure that the controller is in supervisor mode with FIQ's and IRQ's disabled.

Assuming you're using WinForms, as it was the first thing I did when I was starting C# you need to create an event to close this form.

Lets say you've got a button called myNewButton. If you double click it on WinForms designer you will create an event. After that you just have to use this.Close

    private void myNewButton_Click(object sender, EventArgs e) {
        this.Close();
    }

And that should be it.

The only reason for this not working is that your Event is detached from button. But it should create new event if old one is no longer attached when you double click on the button in WinForms designer.

I think you actually provided a good start for the correct answer right in your question (you just need the correct syntax). I had this exact same problem, and putting DISTINCT in a sub-query was indeed less costly than what other answers here have proposed.

select a.FirstName, a.LastName, v.District
from AddTbl a 
inner join (select distinct LastName, District 
    from ValTbl) v
   on a.LastName = v.LastName
order by Firstname   

You can't really "launch an application" in the true sense. You can as you indicated ask the user to open a document (ie a PDF) and windows will attempt to use the default app for that file type. Many applications have a way to do this.

For example you can save RDP connections as a .rdp file. Putting a link on your site to something like this should allow the user to launch right into an RDP session:

<a href="MyServer1.rdp">Server 1</a>

JavaScript

$scope.get_pre = function(x) {
    return $sce.trustAsHtml(x);
};

HTML

<pre ng-bind-html="get_pre(html)"></pre>

On windows 7:

1. Do a search for "cmd" on your Windows computer
   2. right-click cmd and left click "Pin to start menu" (Alternatively, right-click cmd - click copy and then paste to your desktop )
   3. right-click the cmd in your start menu or on your desktop (depending on choice 2 above) - left click properties
   4. inside the "start in" text box paste the location of your default start directory
   5. Press Apply and OK

Every time you click on the cmd in your start menu or your desktop shortcut, the CMD will open in your default location

I had the same issue on a remote windows environment. I tried many solutions found here or on other similars posts but nothing worked. Finally, the solution was quite simple. I had to set NO_PROXY with cmd :

set NO_PROXY="<domain>\<username>:<password>@<host>:<port>"
pip install <packagename>

You have to use double quotes and set NO_PROXY to upper case. You can also add NO_PROXY as an environment variable instead of setting it each time you use the console.

I hope this will help if any other solution posted here works.

Simple short answer is this:

xcopy /Y /I "$(SolutionDir)<my-src-path>" "$(SolutionDir)<my-dst-path>\"

I use it:

$firstDate = date( 'Y-m-d', strtotime( 'Last Monday', strtotime('-1 week') ));
$lastDate = date( 'Y-m-d', strtotime( 'First Sunday', strtotime('-1 week') ));

Hope this help you!

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

I'd like to add on David Hedlund great answer by sharing a more dynamic method than what he posted so it can be used when you do have a negative action to perform and when you don't, i hope it helps.

private void showAlertDialog(@NonNull Context context, @NonNull String alertDialogTitle, @NonNull String alertDialogMessage, @NonNull String positiveButtonText, @Nullable String negativeButtonText, @NonNull final int positiveAction, @Nullable final Integer negativeAction, @NonNull boolean hasNegativeAction)
{
    AlertDialog.Builder builder;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder = new AlertDialog.Builder(context, android.R.style.Theme_Material_Dialog_Alert);
    } else {
        builder = new AlertDialog.Builder(context);
    }
    builder.setTitle(alertDialogTitle)
            .setMessage(alertDialogMessage)
            .setPositiveButton(positiveButtonText, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    switch (positiveAction)
                    {
                        case 1:
                            //TODO:Do your positive action here 
                            break;
                    }
                }
            });
            if(hasNegativeAction || negativeAction!=null || negativeButtonText!=null)
            {
            builder.setNegativeButton(negativeButtonText, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    switch (negativeAction)
                    {
                        case 1:
                            //TODO:Do your negative action here
                            break;
                        //TODO: add cases when needed
                    }
                }
            });
            }
            builder.setIcon(android.R.drawable.ic_dialog_alert);
            builder.show();
}

1. Storing JSON in database violates the first normal form.

   The best thing you can do is to normalize and store features in another table. Then you will be able to use a much better looking and performing query with joins. Your JSON even resembles the table.

2. Mysql 5.7 has builtin JSON functionality:
   http://mysqlserverteam.com/mysql-5-7-lab-release-json-functions-part-2-querying-json-data/

3. Correct pattern is:

   WHERE  `attribs_json` REGEXP '"1":{"value":[^}]*"3"[^}]*}'
   

   [^}] will match any character except }

Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)

Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.

struct foo {
  int bar;
  foo() : bar(3) {}   //look, a constructor
  int getBar() 
  { 
    return bar; 
  }
};

foo f;
int y = f.getBar(); // y is 3

Executing following code from the browser address bar:

javascript: console.log(2);

successfully prints message to the "JavaScript Console" in Google Chrome.

As the jQuery API says: "Load JSON-encoded data from the server using a GET HTTP request."

http://api.jquery.com/jQuery.getJSON/

So you cannot load a local file with that function. But as you browse the web then you will see that loading a file from filesystem is really difficult in javascript as the following thread says:

Local file access with javascript

In my case, I imported a project which has been written on a classmate laptop, the problem is that he was using Java 11 and I was using Java 8, so the project had JDK 11 in it's build path, so I was unable even to import java classes (date, collection,...). So what I've done to solve the problem, is to delete the path of JDK11 and add the my JDK8 path.

Steps:

1. Click on project on the menu bar then properties
2. Choose the libraries tab
3. Click on classpath then on add library from the sidebar
4. Choose the corresponding library to add (remove older ones)

@Franci Penov - modify is possible in the sense of overwrite with /f, eg

reg add "HKCU\Software\etc\etc" /f /v "value" /t REG_SZ /d "Yes"

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

As a Library Project

You should add the resources in a library project as per http://developer.android.com/tools/support-library/setup.html

Section > Adding libraries with resources

You then add the android-support-v7-appcompat library in your workspace and then add it as a reference to your app project.

Defining all the resources in your app project will also work (but there are a lot of definitions to add and you have missed some of them), and it is not the recommended approach.

Even if you use string formatting, sometimes you still need white spaces at the beginning or the end of your string. For these cases, neither escaping with \, nor xml:space attribute helps. You must use HTML entity   for a whitespace.

Use   for non-breakable whitespace.
Use   for regular space.

I got the same error but from a backend job (SSIS job). Upon checking the database's Log file growth setting, the log file was limited growth of 1GB. So what happened is when the job ran and it asked SQL server to allocate more log space, but the growth limit of the log declined caused the job to failed. I modified the log growth and set it to grow by 50MB and Unlimited Growth and the error went away.

I like the answer of coin. It's simple to understand and works with triangles. However the indexes of his program are sometimes over the bounds. So I post here his code with two tiny corrections:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;
    int nextS = (s+1) % sectors;

    indices.push_back(curRow + s);
    indices.push_back(nextRow + s);
    indices.push_back(nextRow + nextS);

    indices.push_back(curRow + s);
    indices.push_back(nextRow + nextS);
    indices.push_back(curRow + nextS);
}

void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
                  float radius, unsigned int rings, unsigned int sectors)
{
    float const R = 1./(float)(rings-1);
    float const S = 1./(float)(sectors-1);

    for(int r = 0; r < rings; ++r) {
        for(int s = 0; s < sectors; ++s) {
            float const y = sin( -M_PI_2 + M_PI * r * R );
            float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
            float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

            texcoords.push_back(vec2(s*S, r*R));
            vertices.push_back(vec3(x,y,z) * radius);
            if(r < rings-1)
                push_indices(indices, sectors, r, s);
        }
    }
}

Usually this region should contains the constructors of the class

This set of utilities to work with the Size abstraction in Android.

It contains a class SizeFromDisplay.java You can use it like this:

ISize size = new SizeFromDisplay(getWindowManager().getDefaultDisplay());
size.width();
size.hight();

Write the function inline, and the interpreter is smart enough to know you're writing a function. Do it like this, and it assumes it's just a string (which it technically is).

go to C:\Windows\System32\drivers\etc and open hosts file and add this

127.0.0.1    example.com
127.0.0.1    www.example.com

then go to C:\xampp\apache\conf\extra open httpd-ajp.conf file and add

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs/pojectroot"
    ServerName example.com
    ServerAlias www.example.com
    <Directory "C:/xampp/htdocs/projectroot">
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

If you want to pass the data on click of browser link, just refer this link.

There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.

One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.

Another short addition to the above mentioned situations is:

• Always unsubscribe, when new values in the subscribed stream is no more required or don't matter, it will result in way less number of triggers and increase in performance in a few cases. Cases such as components where the subscribed data/event no more exists or a new subscription to an all new stream is required (refresh, etc.) is a good example for unsubscription.

It's worth noting that if you use the DownloadManager to kick off your download, be sure to save it to an external location e.g. setDestinationInExternalFilesDir(c, null, "<your name here>).apk";. The intent with a package-archive type doesn't appear to like the content: scheme used with downloads to an internal location, but does like file:. (Trying to wrap the internal path into a File object and then getting the path doesn't work either, even though it results in a file: url, as the app won't parse the apk; looks like it must be external.)

Example:

int uriIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI);
String downloadedPackageUriString = cursor.getString(uriIndex);
File mFile = new File(Uri.parse(downloadedPackageUriString).getPath());
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
        .setDataAndType(Uri.fromFile(mFile), "application/vnd.android.package-archive")
        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
appContext.startActivity(promptInstall);

If you are worried at all about speed, you should instead use:

mag = np.sqrt(x.dot(x))

Here are some benchmarks:

>>> import timeit
>>> timeit.timeit('np.linalg.norm(x)', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0450878
>>> timeit.timeit('np.sqrt(x.dot(x))', setup='import numpy as np; x = np.arange(100)', number=1000)
0.0181372

EDIT: The real speed improvement comes when you have to take the norm of many vectors. Using pure numpy functions doesn't require any for loops. For example:

In [1]: import numpy as np

In [2]: a = np.arange(1200.0).reshape((-1,3))

In [3]: %timeit [np.linalg.norm(x) for x in a]
100 loops, best of 3: 4.23 ms per loop

In [4]: %timeit np.sqrt((a*a).sum(axis=1))
100000 loops, best of 3: 18.9 us per loop

In [5]: np.allclose([np.linalg.norm(x) for x in a],np.sqrt((a*a).sum(axis=1)))
Out[5]: True

If you are not able to find PIA for Office 2013 then follow these steps:

1. Click on Solution Explorer in Visual Studio
2. Right click on your project name (not solution name)
3. Select 'Manage Nuget packages'
4. Click on Browse and search for PIA 2013, choose the shown PIA and click on Install.....

And you are done.

You should be able to install from NuGet (http://www.nuget.org/packages/Microsoft.AspNet.Mvc) into VS2012. Change the Target Framework to .NET 4.5.

Custom Data attribute in HTML5

Would like to quote Ian's comment in my answer:

It's just an attribute (a valid one) on the element that you can use to store data/info about it.

This code then retrieves it later in the event handler, and uses it to find the target output element. It effectively stores the class of the div where its text should be outputted.

reactid is just a suffix, you can have any name here eg: data-Ayman.

If you want to find the difference check the fiddles in this SO answer and comment.

You can do so by extending jQuerys functionality. This will shorten the amount of text you have to write for the selector.

$.extend($.expr[':'], {
        unchecked: function (obj) {
            return ((obj.type == 'checkbox' || obj.type == 'radio') && !$(obj).is(':checked'));
        }
    }
);

You can then use $("input:unchecked") to get all checkboxes and radio buttons that are checked.

Service:

import {Injectable, EventEmitter} from "@angular/core";    

@Injectable()
export class DataService {
onGetData: EventEmitter = new EventEmitter();

getData() {
  this.http.post(...params).map(res => {
    this.onGetData.emit(res.json());
  })
}

Component:

import {Component} from '@angular/core';    
import {DataService} from "../services/data.service";       
    
@Component()
export class MyComponent {
  constructor(private DataService:DataService) {
    this.DataService.onGetData.subscribe(res => {
      (from service on .emit() )
    })
  }

  //To send data to all subscribers from current component
  sendData() {
    this.DataService.onGetData.emit(--NEW DATA--);
  }
}

U can also use CoreImage to create blurred image with dark effect

1. Make snapshot for image

   func snapShotImage() -> UIImage {
       UIGraphicsBeginImageContext(self.frame.size)
       if let context = UIGraphicsGetCurrentContext() {
           self.layer.renderInContext(context)
           let image = UIGraphicsGetImageFromCurrentImageContext()
           UIGraphicsEndImageContext()
           return image
       }
   
       return UIImage()
   }
   

2. Apply CoreImage Filters as u wish with

   private func bluredImage(view:UIView, radius:CGFloat = 1) -> UIImage {
   let image = view.snapShotImage()
   
   if let source = image.CGImage {
       let context = CIContext(options: nil)
       let inputImage = CIImage(CGImage: source)
   
       let clampFilter = CIFilter(name: "CIAffineClamp")
       clampFilter?.setDefaults()
       clampFilter?.setValue(inputImage, forKey: kCIInputImageKey)
   
       if let clampedImage = clampFilter?.valueForKey(kCIOutputImageKey) as? CIImage {
           let explosureFilter = CIFilter(name: "CIExposureAdjust")
           explosureFilter?.setValue(clampedImage, forKey: kCIInputImageKey)
           explosureFilter?.setValue(-1.0, forKey: kCIInputEVKey)
   
           if let explosureImage = explosureFilter?.valueForKey(kCIOutputImageKey) as? CIImage {
               let filter = CIFilter(name: "CIGaussianBlur")
               filter?.setValue(explosureImage, forKey: kCIInputImageKey)
               filter?.setValue("\(radius)", forKey:kCIInputRadiusKey)
   
               if let result = filter?.valueForKey(kCIOutputImageKey) as? CIImage {
                   let bounds = UIScreen.mainScreen().bounds
                   let cgImage = context.createCGImage(result, fromRect: bounds)
                   let returnImage = UIImage(CGImage: cgImage)
                   return returnImage
               }
           }
       }
   }
   return UIImage()
   }
   

Following on from Jakub's answer. git archive produces a tar or zip archive, so you need to pipe the output through tar to get the file content:

git archive --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | tar -x

Will save a copy of 'filename' from the HEAD of the remote repository in the current directory.

The :path/to/directory part is optional. If excluded, the fetched file will be saved to <current working dir>/path/to/directory/filename

In addition, if you want to enable use of git archive --remote on Git repositories hosted by git-daemon, you need to enable the daemon.uploadarch config option. See https://kernel.org/pub/software/scm/git/docs/git-daemon.html

This is the way i ve got the value of a property value of a dinamic:

    public dynamic Post(dynamic value)

        try
        {
            if (value != null)
            {
                var valorCampos = "";

                foreach (Newtonsoft.Json.Linq.JProperty item in value)
                {
                    if (item.Name == "valorCampo")//property name
                        valorCampos = item.Value.ToString();
                }                                           

            }
        }
        catch (Exception ex)
        {

        }


    }

The Enterprise Library configuration editor can help you do this. It allows you to create a base config file and then deltas for each environment. You can then merge the base config and the delta to create an environment-specific web.config. Take a look at the information here which takes you through it better than I can.

I recently encountered this issue while mocking a function in a Kotlin data class. For some unknown reason one of my test runs ended up in a frozen state. When I ran the tests again some of my tests that had previously passed started to fail with the WrongTypeOfReturnValue exception.

I ensured I was using org.mockito:mockito-inline to avoid the issues with final classes (mentioned by Arvidaa), but the problem remained. What solved it for me was to kill the process and restart Android Studio. This terminated my frozen test run and the following test runs passed without issues.

And escape your values with mysql_real_escape_string since PHP6 won't do that for you anymore! :)

It's a named export vs a default export. export const is a named export that exports a const declaration or declarations.

To emphasize: what matters here is the export keyword as const is used to declare a const declaration or declarations. export may also be applied to other declarations such as class or function declarations.

Default Export (export default)

You can have one default export per file. When you import you have to specify a name and import like so:

import MyDefaultExport from "./MyFileWithADefaultExport";

You can give this any name you like.

Named Export (export)

With named exports, you can have multiple named exports per file. Then import the specific exports you want surrounded in braces:

// ex. importing multiple exports:
import { MyClass, MyOtherClass } from "./MyClass";
// ex. giving a named import a different name by using "as":
import { MyClass2 as MyClass2Alias } from "./MyClass2";

// use MyClass, MyOtherClass, and MyClass2Alias here

Or it's possible to use a default along with named imports in the same statement:

import MyDefaultExport, { MyClass, MyOtherClass} from "./MyClass";

Namespace Import

It's also possible to import everything from the file on an object:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass, MyClasses.MyOtherClass and MyClasses.default here

Notes

• The syntax favours default exports as slightly more concise because their use case is more common (See the discussion here).

• A default export is actually a named export with the name default so you are able to import it with a named import:

  import { default as MyDefaultExport } from "./MyFileWithADefaultExport";
  

Because this post is the top one found on stackoverflow when searching for "ORA-00942: table or view does not exist insert", I want to mention another possible cause of this error (at least in Oracle 12c): a table uses a sequence to set a default value and the user executing the insert query does not have select privilege on the sequence. This was my problem and it took me an unnecessarily long time to figure it out.

To reproduce the problem, execute the following SQL as user1:

create sequence seq_customer_id;

create table customer (
c_id number(10) default seq_customer_id.nextval primary key,
name varchar(100) not null,
surname varchar(100) not null
);

grant select, insert, update, delete on customer to user2;

Then, execute this insert statement as user2:

insert into user1.customer (name,surname) values ('michael','jackson');

The result will be "ORA-00942: table or view does not exist" even though user2 does have insert and select privileges on user1.customer table and is correctly prefixing the table with the schema owner name. To avoid the problem, you must grant select privilege on the sequence:

grant select on seq_customer_id to user2;

You can use glob:

import glob, os
os.chdir("/mydir")
for file in glob.glob("*.txt"):
    print(file)

or simply os.listdir:

import os
for file in os.listdir("/mydir"):
    if file.endswith(".txt"):
        print(os.path.join("/mydir", file))

or if you want to traverse directory, use os.walk:

import os
for root, dirs, files in os.walk("/mydir"):
    for file in files:
        if file.endswith(".txt"):
             print(os.path.join(root, file))

Use the length() method in the File class. From the javadocs:

Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

UPDATED Nowadays we should use the Files.size() method:

Paths path = Paths.get("/path/to/file");
long size = Files.size(path);

For the second part of the question, straight from File's javadocs:

• getUsableSpace() Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

• getTotalSpace() Returns the size of the partition named by this abstract pathname

• getFreeSpace() Returns the number of unallocated bytes in the partition named by this abstract path name

Here's a polyfill for the Number predicate functions:

"use strict";

Number.isNaN = Number.isNaN ||
    n => n !== n; // only NaN

Number.isNumeric = Number.isNumeric ||
    n => n === +n; // all numbers excluding NaN

Number.isFinite = Number.isFinite ||
    n => n === +n               // all numbers excluding NaN
      && n >= Number.MIN_VALUE  // and -Infinity
      && n <= Number.MAX_VALUE; // and +Infinity

Number.isInteger = Number.isInteger ||
    n => n === +n              // all numbers excluding NaN
      && n >= Number.MIN_VALUE // and -Infinity
      && n <= Number.MAX_VALUE // and +Infinity
      && !(n % 1);             // and non-whole numbers

Number.isSafeInteger = Number.isSafeInteger ||
    n => n === +n                     // all numbers excluding NaN
      && n >= Number.MIN_SAFE_INTEGER // and small unsafe numbers
      && n <= Number.MAX_SAFE_INTEGER // and big unsafe numbers
      && !(n % 1);                    // and non-whole numbers

All major browsers support these functions, except isNumeric, which is not in the specification because I made it up. Hence, you can reduce the size of this polyfill:

"use strict";

Number.isNumeric = Number.isNumeric ||
    n => n === +n; // all numbers excluding NaN

Alternatively, just inline the expression n === +n manually.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

In your first example, you are making a blank array, same as doing var x = []. The 2nd example makes an array of size 3 (with all elements undefined). The 3rd and 4th examples are the same, they both make arrays with those elements.

Be careful when using new Array().

var x = new Array(10); // array of size 10, all elements undefined
var y = new Array(10, 5); // array of size 2: [10, 5]

The preferred way is using the [] syntax.

var x = []; // array of size 0
var y = [10] // array of size 1: [1]

var z = []; // array of size 0
z[2] = 12;  // z is now size 3: [undefined, undefined, 12]

installing python packages offline

For windows users:

To download into a file open your cmd and folow this:

cd <*the file-path where you want to save it*>

pip download <*package name*>

the package and the dependencies will be downloaded in the current working directory.

To install from the current working directory:

set your folder where you downloaded as the cwd then follow these:

pip install <*the package name which is downloded as .whl*> --no-index --find-links <*the file locaation where the files are downloaded*>

this will search for dependencies in that location.

You can %HOMEDRIVE%%HOMEPATH% for the drive + \docs settings\username or \users\username.

For "100% of the browser window", if you mean this literally, you should use fixed positioning. The top, bottom, right, and left properties are then used to offset the divs edges from the respective edges of the viewport:

#nav, #content{position:fixed;top:0px;bottom:0px;}
#nav{left:0px;right:235px;}
#content{left:235px;right:0px}

This will set up a screen with the left 235 pixels devoted to the nav, and the right rest of the screen to content.

Note, however, you won't be able to scroll the whole screen at once. Though you can set it to scroll either pane individually, by applying overflow:auto to either div.

Note also: fixed positioning is not supported in IE6 or earlier.

This is a simple solution where we do not need to use JSON

public interface RegisterAPI {
@FormUrlEncoded
@POST("/RetrofitExample/insert.php")
public void insertUser(
        @Field("name") String name,
        @Field("username") String username,
        @Field("password") String password,
        @Field("email") String email,
        Callback<Response> callback);
}

method to send data

private void insertUser(){
    //Here we will handle the http request to insert user to mysql db
    //Creating a RestAdapter
    RestAdapter adapter = new RestAdapter.Builder()
            .setEndpoint(ROOT_URL) //Setting the Root URL
            .build(); //Finally building the adapter

    //Creating object for our interface
    RegisterAPI api = adapter.create(RegisterAPI.class);

    //Defining the method insertuser of our interface
    api.insertUser(

            //Passing the values by getting it from editTexts
            editTextName.getText().toString(),
            editTextUsername.getText().toString(),
            editTextPassword.getText().toString(),
            editTextEmail.getText().toString(),

            //Creating an anonymous callback
            new Callback<Response>() {
                @Override
                public void success(Response result, Response response) {
                    //On success we will read the server's output using bufferedreader
                    //Creating a bufferedreader object
                    BufferedReader reader = null;

                    //An string to store output from the server
                    String output = "";

                    try {
                        //Initializing buffered reader
                        reader = new BufferedReader(new InputStreamReader(result.getBody().in()));

                        //Reading the output in the string
                        output = reader.readLine();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    //Displaying the output as a toast
                    Toast.makeText(MainActivity.this, output, Toast.LENGTH_LONG).show();
                }

                @Override
                public void failure(RetrofitError error) {
                    //If any error occured displaying the error as toast
                    Toast.makeText(MainActivity.this, error.toString(),Toast.LENGTH_LONG).show();
                }
            }
    );
}

Now we can get the post request using php aur any other server side scripting.

Use the Linux Command Line

Use the command line, as described in this related question: How do I check if my SSL Certificate is SHA1 or SHA2 on the commandline.

Command

Here's the command. Replace www.yoursite.com:443 to fit your needs. Default SSL port is 443:

openssl s_client -connect www.yoursite.com:443 < /dev/null 2>/dev/null \
    | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm"

Results

This should return something like this for the sha1:

Signature Algorithm: sha1WithRSAEncryption

or this for the newer version:

Signature Algorithm: sha256WithRSAEncryption

References

The article Why Google is Hurrying the Web to Kill SHA-1 describes exactly what you would expect and has a pretty graphic, too.

Here is a nice way to display the information that you want:

SELECT B.table_catalog as 'Database_Name',
         B.table_name as 'Table_Name',
        stuff((select ', ' + A.column_name
              from INFORMATION_SCHEMA.COLUMNS A
              where A.Table_name = B.Table_Name
              FOR XML PATH(''),TYPE).value('(./text())[1]','NVARCHAR(MAX)')
              , 1, 2, '') as 'Columns'
  FROM INFORMATION_SCHEMA.COLUMNS B
  WHERE B.TABLE_NAME like '%%'
        AND B.COLUMN_NAME like '%%'
  GROUP BY B.Table_Catalog, B.Table_Name
  Order by 1 asc

Add anything between either '%%' in the main select to narrow down what tables and/or column names you want.

I also had to remove the SMSS before it would get past that step.

Node.js was created explicitly as an experiment in async processing. The theory was that doing async processing on a single thread could provide more performance and scalability under typical web loads than the typical thread-based implementation.

And you know what? In my opinion that theory's been borne out. A node.js app that isn't doing CPU intensive stuff can run thousands more concurrent connections than Apache or IIS or other thread-based servers.

The single threaded, async nature does make things complicated. But do you honestly think it's more complicated than threading? One race condition can ruin your entire month! Or empty out your thread pool due to some setting somewhere and watch your response time slow to a crawl! Not to mention deadlocks, priority inversions, and all the other gyrations that go with multithreading.

In the end, I don't think it's universally better or worse; it's different, and sometimes it's better and sometimes it's not. Use the right tool for the job.

Old question but I stumbled here so why not take a shot at it since the question is seeking various perspective and not a definitive answer.

w3c may have its recommendations - which I care a lot - but want to rethink since the question is here.

Why does w3c consider domain names be case insensitive and leaves anything afterwards case insensitive ?

I am thinking that the rationale is that the domain part of the URL is hand typed by a user. Everything after being hyper text will be resolved by the machine (browser and server in the back).

Machines can handle case insensitivity better than humans (not the technical kind:)).

But the question is just because the machines CAN handle that should it be done that way ?

I mean what are the benefits of naming and accessing a resource sitting at hereIsTheResource vs hereistheresource ?

The lateral is very unreadable than the camel case one which is more readable. Readable to Humans (including the technical kind.)

So here are my points:-

Resource Path falls in the somewhere in the middle of programming structure and being close to an end user behind the browser sometimes.

Your URL (excluding the domain name) should be case insensitive if your users are expected to touch it or type it etc. You should develop your application to AVOID having users type the path as much as possible.

Your URL (excluding the domain name) should be case sensitive if your users would never type it by hand.

Conclusion

Path should be case sensitive. My points are weighing towards the case sensitive paths.

you need javascript and some client side calculations: http://jsfiddle.net/omegaiori/NERE8/2/

you will need jquery to effectively achieve what you want. this function is very simple but very effective:

(function () {


    var heights = $("#wrapper").outerHeight(true);
    var outerHeights = $("#first").outerHeight(true);
    jQuery('#second').css('height', (heights - outerHeights) + "px");

})();

first it detects the wrapper height, as it is set to 100% it's different everytime (it depends on what screen you are landing). in the second step it gives the #second div the appropriate height subtracting from the wrapper height the #first div height. the result is the available height left in the wrapper div

I was struggling with finding an answer that suited my needs of manually delete a queue in rabbigmq. I therefore think it is worth mentioning in this thread that it is possible to delete a single queue without rabbitmqadmin using the following command:

rabbitmqctl delete_queue <queue_name>

It's plain javascript:

new Date()

#case_date= 03/31/2020   

#Above is the value stored in case_date in format(mm/dd/yyyy )

demo=case_date.split("/")
new_case_date = demo[1]+"-"+demo[0]+"-"+demo[2]
#new format of date is (dd/mm/yyyy) test by printing it 
print(new_case_date)

If you need to do this frequently, I would probably add a computed column PaymentMonth to the table:

ALTER TABLE dbo.Payments ADD PaymentMonth AS MONTH(PaymentDate) PERSISTED

It's persisted and stored in the table - so there's really no performance overhead querying it. It's a 4 byte INT value - so the space overhead is minimal, too.

Once you have that, you could simplify your query to be something along the lines of:

SELECT ItemID, IsPaid,
(SELECT SUM(Amount) FROM Payments WHERE Year = 2010 And PaymentMonth = 1 AND UserID = 100) AS 'Jan',
(SELECT SUM(Amount) FROM Payments WHERE Year = 2010 And PaymentMonth = 2 AND UserID = 100) AS 'Feb',
.... and so on .....
FROM LIVE L 
INNER JOIN Payments I ON I.LiveID = L.RECORD_KEY 
WHERE UserID = 16178 

In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <Preference
        android:key="pref_edit_recipe_key"
        android:title="Add/Edit Recipe">
        <intent
            android:action="android.intent.action.VIEW"
            android:targetPackage="com.ssimon.olddirectory"
            android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
    </Preference>
</PreferenceScreen> 

I needed the following instead:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <Preference
        android:key="pref_edit_recipe_key"
        android:title="Add/Edit Recipe">
        <intent
            android:action="android.intent.action.VIEW"
            android:targetPackage="com.ssimon.newdirectory"
            android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>

Correcting the path names fixed the problem.

I faced this exception for a long time and was not able to pinpoint the problem. The exception says line 1 column 9. The mistake I did is to get the first line of the file which flume is processing.

Apache flume process the content of the file in patches. So, when flume throws this exception and says line 1, it means the first line in the current patch.

If your flume agent is configured to use batch size = 100, and (for example) the file contains 400 lines, this means the exception is thrown in one of the following lines 1, 101, 201,301.

How to discover the line which causes the problem?

You have three ways to do that.

1- pull the source code and run the agent in debug mode. If you are an average developer like me and do not know how to make this, check the other two options.

2- Try to split the file based on the batch size and run the flume agent again. If you split the file into 4 files, and the invalid json exists between lines 301 and 400, the flume agent will process the first 3 files and stop at the fourth file. Take the fourth file and again split it into more smaller files. continue the process until you reach a file with only one line and flume fails while processing it.

3- Reduce the batch size of the flume agent to only one and compare the number of processed events in the output of the sink you are using. For example, in my case I am using Solr sink. The file contains 400 lines. The flume agent is configured with batch size=100. When I run the flume agent, it fails at some point and throw that exception. At this point check how many documents are ingested in Solr. If the invalid json exists at line 346, the number of documents indexed into Solr will be 345, so the next line is the line which causes the problem.

In my case I followed the third option and fortunately I pinpoint the line which causes the problem.

This is a long answer but it actually does not solve the exception. How I overcome this exception?

I have no idea why Jackson library complain while parsing a json string contains escaped characters \n \r \t. I think (but I am not sure) the Jackson parser is by default escaping these characters which cases the json string to be split into two lines (in case of \n) and then it deals each line as a separate json string.

In my case we used a customized interceptor to remove these characters before being processed by the flume agent. This is the way we solved this problem.

It's a good idea too to check that you are not trying to pass an undefined term.

function TestMe() {
  if((typeof str != 'undefined') && str) {
    alert(str);
  }
 };

TestMe();

var str = 'hello';

TestMe();

I usually run into the case where I want to do something when a string attribute for an object instance is not empty. Which is fine, except that attribute is not always present.

You can also use functions with $filter('filter'):

var foo = $filter('filter')($scope.results.subjects, function (item) {
  return item.grade !== 'A';
});

On Windows, you may be silently blocked by your Antivirus or Windows firewall. Temporarily turn off those services and push/pull from remote origin.

If you would like to ignore case you could use the following:

String s = "yip";
String best = "yodel";
int compare = s.compareToIgnoreCase(best);
if(compare < 0){
    //-1, --> s is less than best. ( s comes alphabetically first)
}
else if(compare > 0 ){
// best comes alphabetically first.
}
else{
    // strings are equal.
}

If your table is MyISAM:

SELECT  *
FROM    pages
WHERE   MATCH(title, content) AGAINST ('keyword' IN BOOLEAN MODE)

This will be much faster if you create a FULLTEXT index on your columns:

CREATE FULLTEXT INDEX fx_pages_title_content ON pages (title, content)

, but will work even without the index.

In App.config:

<add key="YOURKEY" value="a,b,c"/>

In C#:

string[] InFormOfStringArray = ConfigurationManager.AppSettings["YOURKEY"].Split(',').Select(s => s.Trim()).ToArray();
List<string> list = new List<string>(InFormOfStringArray);

You're receiving this error because you did not pass a data variable to the DHT constructor.

aIKid and Alexander's answers are nice but it wont work because you still have to initialize self.data in the class constructor like this:

class DHT:
   def __init__(self, data=None):
      if data is None:
         data = {}
      else:
         self.data = data
      self.data['one'] = '1'
      self.data['two'] = '2'
      self.data['three'] = '3'
   def showData(self):
      print(self.data)

And then calling the method showData like this:

DHT().showData()

Or like this:

DHT({'six':6,'seven':'7'}).showData()

or like this:

# Build the class first
dht = DHT({'six':6,'seven':'7'})
# The call whatever method you want (In our case only 1 method available)
dht.showData()

How about:

if('functionName' in Obj){
    //code
}

e.g.

var color1 = new String("green");
"length" in color1 // returns true
"indexOf" in color1 // returns true
"blablabla" in color1 // returns false

or as for your case:

if('onChange' in me){
    //code
}

See MDN docs.

Defining a NAME containing the lookup is a neat solution, HOWEVER, it always seems to store the sheet name with the cell reference. However, I think if you delete the sheet name in the '' quotes but leave the "!", it may work.

The general approach to this is to:

1. Get the time at the start of your benchmark, say at the start of main().
2. Run your code.
3. Get the time at the end of your benchmark, say at the end of main().
4. Subtract the start time from the end time and convert into appropriate units.

A hint: look at System.nanoTime() or System.currentTimeMillis().

 select * 
 from [ServerName(IP)].[DatabaseName].[dbo].[TableName]

Use \W which is equivalent to [^a-zA-Z0-9_]. Check the documentation, https://docs.python.org/2/library/re.html

Import re
s =  'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'

update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.

To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.

protected override void OnConfiguring(DbContextOptionsBuilder options)
        => options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");

To use the EF core SqlServer provider and compile the above code install the EF SqlServer package

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

After compilation before running the code do the following for the first time

dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update

To run the code

dotnet run

A python string is a list of characters. You can iterate over it right now!

justdigits = ""
for char in string:
    if char.isdigit():
        justdigits += str(char)

You need to modify the method GetData() and add your "experimental" code there, and return t1.

Using an in can have a performance impact. Joining two subqueries will not have the same performance impact and can be accomplished like this:

SELECT *
  FROM (SELECT msisdn
              ,callid
              ,Change_color
              ,play_file_name
              ,date_played
          FROM insert_log
         WHERE play_file_name NOT IN('Prompt1','Conclusion_Prompt_1','silent')
        ORDER BY callid ASC) t1
       JOIN (SELECT MAX(date_played) AS date_played
               FROM insert_log GROUP BY callid) t2
         ON t1.date_played = t2.date_played

A flexible solution with Java 8 lambda that lets you provide a Consumer that will process the output (eg. log it) line by line. run() is a one-liner with no checked exceptions thrown. Alternatively to implementing Runnable, it can extend Thread instead as other answers suggest.

class StreamGobbler implements Runnable {
    private InputStream inputStream;
    private Consumer<String> consumeInputLine;

    public StreamGobbler(InputStream inputStream, Consumer<String> consumeInputLine) {
        this.inputStream = inputStream;
        this.consumeInputLine = consumeInputLine;
    }

    public void run() {
        new BufferedReader(new InputStreamReader(inputStream)).lines().forEach(consumeInputLine);
    }
}

You can then use it for example like this:

public void runProcessWithGobblers() throws IOException, InterruptedException {
    Process p = new ProcessBuilder("...").start();
    Logger logger = LoggerFactory.getLogger(getClass());

    StreamGobbler outputGobbler = new StreamGobbler(p.getInputStream(), System.out::println);
    StreamGobbler errorGobbler = new StreamGobbler(p.getErrorStream(), logger::error);

    new Thread(outputGobbler).start();
    new Thread(errorGobbler).start();
    p.waitFor();
}

Here the output stream is redirected to System.out and the error stream is logged on the error level by the logger.

Classic javascript mistake.

setTimeout(function(){this.setState({timePassed: true})}, 1000)

When setTimeout runs this.setState, this is no longer CowtanApp, but window. If you define the function with the => notation, es6 will auto-bind this.

setTimeout(() => {this.setState({timePassed: true})}, 1000)

Alternatively, you could use a let that = this; at the top of your render, then switch your references to use the local variable.

render() {
  let that = this;
  setTimeout(function(){that.setState({timePassed: true})}, 1000);

If not working, use bind.

setTimeout(
  function() {
      this.setState({timePassed: true});
  }
  .bind(this),
  1000
);

Have a look at the following example of the jQueryUI Autocomplete, as it is keeping a select around and I think that is what you are looking for. Hope this helps.

I think what you're trying to do is wrap loooooooooooooong words or URLs so they don't push the size of the table out. (I've just been trying to do the same thing!)

You can do this easily with a DIV by giving it the style word-wrap: break-word (and you may need to set its width, too).

div {
    word-wrap: break-word;         /* All browsers since IE 5.5+ */
    overflow-wrap: break-word;     /* Renamed property in CSS3 draft spec */
    width: 100%;
}

However, for tables, you must either wrap the content in a DIV (or other block tag) or apply: table-layout: fixed. This means the columns widths are no longer fluid, but are defined based on the widths of the columns in the first row only (or via specified widths). Read more here.

Sample code:

table {
    table-layout: fixed;
    width: 100%;
}

table td {
    word-wrap: break-word;         /* All browsers since IE 5.5+ */
    overflow-wrap: break-word;     /* Renamed property in CSS3 draft spec */
}

Hope that helps somebody.

This is what you're looking for:

List<String> dan = Arrays.asList("Red", "Orange", "Yellow", "Green", "Blue", "Violet", "Orange", "Blue");

boolean contains = dan.contains(say.getText());

If you have a list of not repeated values, prefer using a Set<String> which has the same contains method

I've the same problem just today. This is my solution (which I think is better and simpler):

<!-- Modal dialog -->
<div class="modal fade" id="frmPrenotazione" tabindex="-1">
    <!-- CUTTED -->
    <div id="step1" class="modal-footer">
      <button type="button" class="glyphicon glyphicon-erase btn btn-default" id="btnDelete"> Delete</button>
    </div>
</div>

<!-- Modal confirm -->
<div class="modal" id="confirmModal" style="display: none; z-index: 1050;">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body" id="confirmMessage">
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" id="confirmOk">Ok</button>
                <button type="button" class="btn btn-default" id="confirmCancel">Cancel</button>
            </div>
        </div>
    </div>
</div>

And in my .js:

$('#btnDelete').on('click', function(e){
    confirmDialog(YOUR_MESSAGE_STRING_CONST, function(){
        //My code to delete
    });
});

function confirmDialog(message, onConfirm){
    var fClose = function(){
        modal.modal("hide");
    };
    var modal = $("#confirmModal");
    modal.modal("show");
    $("#confirmMessage").empty().append(message);
    $("#confirmOk").unbind().one('click', onConfirm).one('click', fClose);
    $("#confirmCancel").unbind().one("click", fClose);
}

Using unbind before the one prevents that the removal function is invoked at the next opening of the dialog.

I hope this could be helpful.

Follow a complete example:

var YOUR_MESSAGE_STRING_CONST = "Your confirm message?";_x000D_
      $('#btnDelete').on('click', function(e){_x000D_
      confirmDialog(YOUR_MESSAGE_STRING_CONST, function(){_x000D_

SQLite can use text, real, or integer data types to store dates. Even more, whenever you perform a query, the results are shown using format %Y-%m-%d %H:%M:%S.

Now, if you insert/update date/time values using SQLite date/time functions, you can actually store milliseconds as well. If that's the case, the results are shown using format %Y-%m-%d %H:%M:%f. For example:

sqlite> create table test_table(col1 text, col2 real, col3 integer);
sqlite> insert into test_table values (
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.123'),
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.123'),
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.123')
        );
sqlite> insert into test_table values (
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.126'),
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.126'),
            strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.126')
        );
sqlite> select * from test_table;
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123
2014-03-01 13:01:01.126|2014-03-01 13:01:01.126|2014-03-01 13:01:01.126

Now, doing some queries to verify if we are actually able to compare times:

sqlite> select * from test_table /* using col1 */
           where col1 between 
               strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.121') and
               strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.125');
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123

You can check the same SELECT using col2 and col3 and you will get the same results. As you can see, the second row (126 milliseconds) is not returned.

Note that BETWEEN is inclusive, therefore...

sqlite> select * from test_table 
            where col1 between 
                 /* Note that we are using 123 milliseconds down _here_ */
                strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.123') and
                strftime('%Y-%m-%d %H:%M:%f', '2014-03-01 13:01:01.125');

... will return the same set.

Try playing around with different date/time ranges and everything will behave as expected.

What about without strftime function?

sqlite> select * from test_table /* using col1 */
           where col1 between 
               '2014-03-01 13:01:01.121' and
               '2014-03-01 13:01:01.125';
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123

What about without strftime function and no milliseconds?

sqlite> select * from test_table /* using col1 */
           where col1 between 
               '2014-03-01 13:01:01' and
               '2014-03-01 13:01:02';
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123
2014-03-01 13:01:01.126|2014-03-01 13:01:01.126|2014-03-01 13:01:01.126

What about ORDER BY?

sqlite> select * from test_table order by 1 desc;
2014-03-01 13:01:01.126|2014-03-01 13:01:01.126|2014-03-01 13:01:01.126
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123
sqlite> select * from test_table order by 1 asc;
2014-03-01 13:01:01.123|2014-03-01 13:01:01.123|2014-03-01 13:01:01.123
2014-03-01 13:01:01.126|2014-03-01 13:01:01.126|2014-03-01 13:01:01.126

Works just fine.

Finally, when dealing with actual operations within a program (without using the sqlite executable...)

BTW: I'm using JDBC (not sure about other languages)... the sqlite-jdbc driver v3.7.2 from xerial - maybe newer revisions change the behavior explained below... If you are developing in Android, you don't need a jdbc-driver. All SQL operations can be submitted using the SQLiteOpenHelper.

JDBC has different methods to get actual date/time values from a database: java.sql.Date, java.sql.Time, and java.sql.Timestamp.

The related methods in java.sql.ResultSet are (obviously) getDate(..), getTime(..), and getTimestamp() respectively.

For example:

Statement stmt = ... // Get statement from connection
ResultSet rs = stmt.executeQuery("SELECT * FROM TEST_TABLE");
while (rs.next()) {
    System.out.println("COL1 : "+rs.getDate("COL1"));
    System.out.println("COL1 : "+rs.getTime("COL1"));
    System.out.println("COL1 : "+rs.getTimestamp("COL1"));
    System.out.println("COL2 : "+rs.getDate("COL2"));
    System.out.println("COL2 : "+rs.getTime("COL2"));
    System.out.println("COL2 : "+rs.getTimestamp("COL2"));
    System.out.println("COL3 : "+rs.getDate("COL3"));
    System.out.println("COL3 : "+rs.getTime("COL3"));
    System.out.println("COL3 : "+rs.getTimestamp("COL3"));
}
// close rs and stmt.

Since SQLite doesn't have an actual DATE/TIME/TIMESTAMP data type all these 3 methods return values as if the objects were initialized with 0:

new java.sql.Date(0)
new java.sql.Time(0)
new java.sql.Timestamp(0)

So, the question is: how can we actually select, insert, or update Date/Time/Timestamp objects? There's no easy answer. You can try different combinations, but they will force you to embed SQLite functions in all the SQL statements. It's far easier to define an utility class to transform text to Date objects inside your Java program. But always remember that SQLite transforms any date value to UTC+0000.

In summary, despite the general rule to always use the correct data type, or, even integers denoting Unix time (milliseconds since epoch), I find much easier using the default SQLite format ('%Y-%m-%d %H:%M:%f' or in Java 'yyyy-MM-dd HH:mm:ss.SSS') rather to complicate all your SQL statements with SQLite functions. The former approach is much easier to maintain.

TODO: I will check the results when using getDate/getTime/getTimestamp inside Android (API15 or better)... maybe the internal driver is different from sqlite-jdbc...

Using Redux-saga

As Dan Abramov said, if you want more advanced control over your async code, you might take a look at redux-saga.

This answer is a simple example, if you want better explanations on why redux-saga can be useful for your application, check this other answer.

The general idea is that Redux-saga offers an ES6 generators interpreter that permits you to easily write async code that looks like synchronous code (this is why you'll often find infinite while loops in Redux-saga). Somehow, Redux-saga is building its own language directly inside Javascript. Redux-saga can feel a bit difficult to learn at first, because you need basic understanding of generators, but also understand the language offered by Redux-saga.

I'll try here to describe here the notification system I built on top of redux-saga. This example currently runs in production.

Advanced notification system specification

• You can request a notification to be displayed
• You can request a notification to hide
• A notification should not be displayed more than 4 seconds
• Multiple notifications can be displayed at the same time
• No more than 3 notifications can be displayed at the same time
• If a notification is requested while there are already 3 displayed notifications, then queue/postpone it.

Result

Screenshot of my production app Stample.co

Code

Here I named the notification a toast but this is a naming detail.

function* toastSaga() {

    // Some config constants
    const MaxToasts = 3;
    const ToastDisplayTime = 4000;


    // Local generator state: you can put this state in Redux store
    // if it's really important to you, in my case it's not really
    let pendingToasts = []; // A queue of toasts waiting to be displayed
    let activeToasts = []; // Toasts currently displayed


    // Trigger the display of a toast for 4 seconds
    function* displayToast(toast) {
        if ( activeToasts.length >= MaxToasts ) {
            throw new Error("can't display more than " + MaxToasts + " at the same time");
        }
        activeToasts = [...activeToasts,toast]; // Add to active toasts
        yield put(events.toastDisplayed(toast)); // Display the toast (put means dispatch)
        yield call(delay,ToastDisplayTime); // Wait 4 seconds
        yield put(events.toastHidden(toast)); // Hide the toast
        activeToasts = _.without(activeToasts,toast); // Remove from active toasts
    }

    // Everytime we receive a toast display request, we put that request in the queue
    function* toastRequestsWatcher() {
        while ( true ) {
            // Take means the saga will block until TOAST_DISPLAY_REQUESTED action is dispatched
            const event = yield take(Names.TOAST_DISPLAY_REQUESTED);
            const newToast = event.data.toastData;
            pendingToasts = [...pendingToasts,newToast];
        }
    }


    // We try to read the queued toasts periodically and display a toast if it's a good time to do so...
    function* toastScheduler() {
        while ( true ) {
            const canDisplayToast = activeToasts.length < MaxToasts && pendingToasts.length > 0;
            if ( canDisplayToast ) {
                // We display the first pending toast of the queue
                const [firstToast,...remainingToasts] = pendingToasts;
                pendingToasts = remainingToasts;
                // Fork means we are creating a subprocess that will handle the display of a single toast
                yield fork(displayToast,firstToast);
                // Add little delay so that 2 concurrent toast requests aren't display at the same time
                yield call(delay,300);
            }
            else {
                yield call(delay,50);
            }
        }
    }

    // This toast saga is a composition of 2 smaller "sub-sagas" (we could also have used fork/spawn effects here, the difference is quite subtile: it depends if you want toastSaga to block)
    yield [
        call(toastRequestsWatcher),
        call(toastScheduler)
    ]
}

And the reducer:

const reducer = (state = [],event) => {
    switch (event.name) {
        case Names.TOAST_DISPLAYED:
            return [...state,event.data.toastData];
        case Names.TOAST_HIDDEN:
            return _.without(state,event.data.toastData);
        default:
            return state;
    }
};

Usage

You can simply dispatch TOAST_DISPLAY_REQUESTED events. If you dispatch 4 requests, only 3 notifications will be displayed, and the 4th one will appear a bit later once the 1st notification disappears.

Note that I don't specifically recommend dispatching TOAST_DISPLAY_REQUESTED from JSX. You'd rather add another saga that listens to your already-existing app events, and then dispatch the TOAST_DISPLAY_REQUESTED: your component that triggers the notification, does not have to be tightly coupled to the notification system.

Conclusion

My code is not perfect but runs in production with 0 bugs for months. Redux-saga and generators are a bit hard initially but once you understand them this kind of system is pretty easy to build.

It's even quite easy to implement more complex rules, like:

• when too many notifications are "queued", give less display-time for each notification so that the queue size can decrease faster.
• detect window size changes, and change the maximum number of displayed notifications accordingly (for example, desktop=3, phone portrait = 2, phone landscape = 1)

Honnestly, good luck implementing this kind of stuff properly with thunks.

Note you can do exactly the same kind of thing with redux-observable which is very similar to redux-saga. It's almost the same and is a matter of taste between generators and RxJS.

$('input[type=text],select', '.sys');

for looping:

$('input[type=text],select', '.sys').each(function() {
   // code
});

I would like to specify something. If someone want to get the whole url with path like I need, can use:

var fullUrl = window.location.protocol + "//" + window.location.hostname + window.location.pathname;

string.split("=", 2);

As String.split(java.lang.String regex, int limit) explains:

The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string. The substrings in the array are in the order in which they occur in this string. If the expression does not match any part of the input then the resulting array has just one element, namely this string.

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter.

The string boo:and:foo, for example, yields the following results with these parameters:

Regex Limit    Result
:     2        { "boo", "and:foo" }
:     5        { "boo", "and", "foo" }
:    -2        { "boo", "and", "foo" }
o     5        { "b", "", ":and:f", "", "" }
o    -2        { "b", "", ":and:f", "", "" }
o     0        { "b", "", ":and:f" }

__pycache__ is a folder containing Python 3 bytecode compiled and ready to be executed.

I don't recommend routinely deleting these files or suppressing creation during development as it may hurt performance. Just have a recursive command ready (see below) to clean up when needed as bytecode can become stale in edge cases (see comments).

Python programmers usually ignore bytecode. Indeed __pycache__ and *.pyc are common lines to see in .gitignore files. Bytecode is not meant for distribution and can be disassembled using dis module.

If you are using OS X you can easily hide all of these folders in your project by running following command from the root folder of your project.

find . -name '__pycache__' -exec chflags hidden {} \;

Replace __pycache__ with *.pyc for Python 2.

This sets a flag on all those directories (.pyc files) telling Finder/Textmate 2 to exclude them from listings. Importantly the bytecode is there, it's just hidden.

Rerun the command if you create new modules and wish to hide new bytecode or if you delete the hidden bytecode files.

On Windows the equivalent command might be (not tested, batch script welcome):

dir * /s/b | findstr __pycache__ | attrib +h +s +r

Which is same as going through the project hiding folders using right-click > hide...

Running unit tests is one scenario (more in comments) where deleting the *.pyc files and __pycache__ folders is indeed useful. I use the following lines in my ~/.bash_profile and just run cl to clean up when needed.

alias cpy='find . -name "__pycache__" -delete'
alias cpc='find . -name "*.pyc"       -delete'
...
alias cl='cpy && cpc && ...'

and more lately

# pip install pyclean
pyclean .

In addition to what's already been said, don't use ToString() on the exception object for displaying to the user. Just the Message property should suffice, or a higher level custom message.

In terms of logging purposes, definitely use ToString() on the Exception, not just the Message property, as in most scenarios, you will be left scratching your head where specifically this exception occurred, and what the call stack was. The stacktrace would have told you all that.

Adding into this: it depends on what your array is defined as. Consider:

dim a() as integer
dim b() as string
dim c() as variant

'these doesn't work
if isempty(a) then msgbox "integer arrays can be empty"
if isempty(b) then msgbox "string arrays can be empty"

'this is because isempty can only be tested on classes which have an .empty property

'this do work
if isempty(c) then msgbox "variants can be empty"

So, what can we do? In VBA, we can see if we can trigger an error and somehow handle it, for example

dim a() as integer
dim bEmpty as boolean

bempty=false

on error resume next
bempty=not isnumeric(ubound(a))
on error goto 0

But this is really clumsy... A nicer solution is to declare a boolean variable (a public or module level is best). When the array is first initialised, then set this variable. Because it's a variable declared at the same time, if it loses it's value, then you know that you need to reinitialise your array. However, if it is initialised, then all you're doing is checking the value of a boolean, which is low cost. It depends on whether being low cost matters, and if you're going to be needing to check it often.

option explicit

'declared at module level
dim a() as integer
dim aInitialised as boolean

sub DoSomethingWithA()
if not aInitialised then InitialiseA
'you can now proceed confident that a() is intialised
end sub

sub InitialiseA()
'insert code to do whatever is required to initialise A
'e.g. 
redim a(10)
a(1)=123
'...
aInitialised=true
end sub

The last thing you can do is create a function; which in this case will need to be dependent on the clumsy on error method.

function isInitialised(byref a() as variant) as boolean
isInitialised=false
on error resume next
isinitialised=isnumeric(ubound(a))
end function

Here are two extension methods you can use. They ensure any existing classes are preserved and do not duplicate classes being added.

public static void RemoveCssClass(this WebControl control, String css) {
  control.CssClass = String.Join(" ", control.CssClass.Split(' ').Where(x => x != css).ToArray());
}

public static void AddCssClass(this WebControl control, String css) {
  control.RemoveCssClass(css);
  css += " " + control.CssClass;
  control.CssClass = css;
}

Usage: hlCreateNew.AddCssClass("disabled");

Usage: hlCreateNew.RemoveCssClass("disabled");

I came across this question when trying to check if a file existed on an FTP site or not. If the file doesn't exist there will be an error when trying to check its timestamp. But I want to make sure the error is not something else, by checking its type.

The Response property on WebException will be of type FtpWebResponse on which you can check its StatusCode property to see which FTP error you have.

Here's the code I ended up with:

    public static bool FileExists(string host, string username, string password, string filename)
    {
        // create FTP request
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + host + "/" + filename);
        request.Credentials = new NetworkCredential(username, password);

        // we want to get date stamp - to see if the file exists
        request.Method = WebRequestMethods.Ftp.GetDateTimestamp;

        try
        {
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            var lastModified = response.LastModified;

            // if we get the last modified date then the file exists
            return true;
        }
        catch (WebException ex)
        {
            var ftpResponse = (FtpWebResponse)ex.Response;

            // if the status code is 'file unavailable' then the file doesn't exist
            // may be different depending upon FTP server software
            if (ftpResponse.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
            {
                return false;
            }

            // some other error - like maybe internet is down
            throw;
        }
    }

With this type of thing you need to be careful what your actual working directory is. For example, you may not run the script from the directory the file is in. In this case, you can't just use a relative path by itself.

If you are sure the file you want is in a subdirectory beneath where the script is actually located, you can use __file__ to help you out here. __file__ is the full path to where the script you are running is located.

So you can fiddle with something like this:

import os
script_dir = os.path.dirname(__file__) #<-- absolute dir the script is in
rel_path = "2091/data.txt"
abs_file_path = os.path.join(script_dir, rel_path)

When dealing with VARCHAR/NVARCHAR data most other examples treat white-space the same as empty string which is equal to C# function IsNullOrWhiteSpace.

This version respects white-space and works the same as the C# function IsNullOrEmpty:

IIF(ISNULL(DATALENGTH(val), 0) = 0, whenTrueValue, whenFalseValue)

Simple test:

SELECT
    '"' + val + '"' AS [StrValue],
    IIF(ISNULL(DATALENGTH(val), 0) = 0, 'TRUE', 'FALSE') AS IsNullOrEmpty
FROM ( VALUES 
    (NULL), 
    (''), 
    (' '), 
    ('a'), 
    ('a ')
) S (val)

WARNING: git clean -f will remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.

Try this and see git clean -f.

git reset --hard will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under Git tracking.

Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)

• git clean -df
• git clean -xdf CAUTION! This will also delete ignored files

Building on Sklivvz' answer, here's a nice function one can put in a .bash_aliases file. It is efficient on huge files when printing stuff from the front of the file.

function middle()
{
    startidx=$1
    len=$2
    endidx=$(($startidx+$len))
    filename=$3

    awk "FNR>=${startidx} && FNR<=${endidx} { print NR\" \"\$0 }; FNR>${endidx} { print \"END HERE\"; exit }" $filename
}

change the div to display block

.topbar{
    display:block;
    width:100%;
    height:70px;
    background-color:#475;
    overflow:scroll;
    }

The below might help anyone that is looking to reverse a string recursively. Was asked to do this in a recent job interview using functional programming style:

var reverseStr = function(str) {
    return (str.length > 0) ? str[str.length - 1] + reverseStr(str.substr(0, str.length -   1)) : '';
};

//tests
console.log(reverseStr('setab retsam')); //master bates

Display array in beautiful way:

function arrayDisplay($input)
{
    return implode(
        ', ',
        array_map(
            function ($v, $k) {
                return sprintf("%s => '%s'", $k, $v);
            },
            $input,
            array_keys($input)
        )
    );
}

$arr = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo arrayDisplay($arr);

Displays:

foo => 'bar', baz => 'boom', cow => 'milk', php => 'hypertext processor'

The answer above seemed to comment out too much for the solution I reached. This is what my file looked like:

/etc/nginx/sites-available/default

location ~ \.php$ {
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

Hope this helps some folks who are frustrated on a sunday afternoon (c:

In iOS 5 there is a new and easy way to this. I'm not sure if the implementation is fully complete yet as it's not a gracious as, say, a UITableViewCell, but it should definitly do the trick as it is now standard supported in the iOS API. You will not need a private API for this.

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"This is an example alert!" delegate:self cancelButtonTitle:@"Hide" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
[alert release];

This renders an alertView like this (screenshot taken from the iPhone 5.0 simulator in XCode 4.2):

When pressing any buttons, the regular delegate methods will be called and you can extract the textInput there like so:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ 
    NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);
}

Here I just NSLog the results that were entered. In production code, you should probably keep a pointer to your alertView as a global variable or use the alertView tag to check if the delegate function was called by the appropriate UIAlertView but for this example this should be okay.

You should check out the UIAlertView API and you'll see there are some more styles defined.

Hope this helped!

-- EDIT --

I was playing around with the alertView a little and I suppose it needs no announcement that it's perfectly possible to edit the textField as desired: you can create a reference to the UITextField and edit it as normal (programmatically). Doing this I constructed an alertView as you specified in your original question. Better late than never, right :-)?

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeNumberPad;
alertTextField.placeholder = @"Enter your name";
[alert show];
[alert release];

This produces this alert:

You can use the same delegate method as I poster earlier to process the result from the input. I'm not sure if you can prevent the UIAlertView from dismissing though (there is no shouldDismiss delegate function AFAIK) so I suppose if the user input is invalid, you have to put up a new alert (or just reshow this one) until correct input was entered.

Have fun!

I solved this way, when I had to use the foreach index and value in the same context:

$array = array('a', 'b', 'c');
foreach ($array as $letter=>$index) {

  echo $letter; //Here $letter content is the actual index
  echo $array[$letter]; // echoes the array value

}//foreach

It means "a python object", i.e. not one of the builtin scalar types supported by numpy.

np.array([object()]).dtype
=> dtype('O')

I know that the question was how to do it with Jquery, but you can achieve the same affect with simple css and just a little jquery...

For example, you have a div with 'box' class, add the following css

.box {
background-color: black;
-webkit-transition: background 0.5s linear;
-moz-transition: background 0.5s linear;
-ms-transition: background 0.5s linear;
-o-transition: background 0.5s linear;
transition: background 0.5s linear;
}

and then use AddClass function to add another class with different background color like 'box highlighted' or something like that with the following css:

.box.highlighted {
  background-color: white;
}

I am a beginner and maybe there are some disadvantages of this method but maybe it'll be helpful for somebody

Here's a codepen: https://codepen.io/anon/pen/baaLYB

On jQuery for designers there's a well written post about this, this is the jQuery snippet that does the magic. just replace #comment with the selector of the div that you want to float.

Note: To see the whole article go here: http://jqueryfordesigners.com/fixed-floating-elements/

$(document).ready(function () {
  var $obj = $('#comment');
  var top = $obj.offset().top - parseFloat($obj.css('marginTop').replace(/auto/, 0));

  $(window).scroll(function (event) {
    // what the y position of the scroll is
    var y = $(this).scrollTop();

    // whether that's below the form
    if (y >= top) {
      // if so, ad the fixed class
      $obj.addClass('fixed');
    } else {
      // otherwise remove it
      $obj.removeClass('fixed');
    }
  });
});

According to SLF4J official documentation

Failed to load class org.slf4j.impl.StaticLoggerBinder

This warning message is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

Simply add this jar along with slf4j api.jar to your classpath to get things done. Best of luck

There should be a program called dos2unix that will fix line endings for you. If it's not already on your Linux box, it should be available via the package manager.

First of all I'd like to say that all users who said about lazy and transactions were right. But in my case there was a slight difference in that I used result of @Transactional method in a test and that was outside real transaction so I got this lazy exception.

My service method:

@Transactional
User get(String uid) {};

My test code:

User user = userService.get("123");
user.getActors(); //org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role

My solution to this was wrapping that code in another transaction like this:

List<Actor> actors = new ArrayList<>();
transactionTemplate.execute((status) 
 -> actors.addAll(userService.get("123").getActors()));

df = pd.DataFrame({'movie': ['thg', 'thg', 'mol', 'mol', 'lob', 'lob'],'rating': [3., 4., 5., np.nan, np.nan, np.nan],'name': ['John','James', np.nan, np.nan, np.nan,np.nan]})

for col in df.columns:
    df = df[~pd.isnull(df[col])]

Yes. Fetch the repository and then cherry-pick from the remote branch.

Instead of writing a form into the new window (which is tricky to get correct, with encoding of values in the HTML code), just open an empty window and post a form to it.

Example:

<form id="TheForm" method="post" action="test.asp" target="TheWindow">
<input type="hidden" name="something" value="something" />
<input type="hidden" name="more" value="something" />
<input type="hidden" name="other" value="something" />
</form>

<script type="text/javascript">
window.open('', 'TheWindow');
document.getElementById('TheForm').submit();
</script>

Edit:

To set the values in the form dynamically, you can do like this:

function openWindowWithPost(something, additional, misc) {
  var f = document.getElementById('TheForm');
  f.something.value = something;
  f.more.value = additional;
  f.other.value = misc;
  window.open('', 'TheWindow');
  f.submit();
}

To post the form you call the function with the values, like openWindowWithPost('a','b','c');.

Note: I varied the parameter names in relation to the form names to show that they don't have to be the same. Usually you would keep them similar to each other to make it simpler to track the values.

If anyone comes looking for first day of previous month and last day of previous month:

public static LocalDate firstDayOfPreviousMonth(LocalDate date) {
        return date.minusMonths(1).withDayOfMonth(1);
    }


public static LocalDate lastDayOfPreviousMonth(LocalDate date) {
        return date.withDayOfMonth(1).minusDays(1);
    }

Here is what I believe answers the question (Python 3, with type hints):

from datetime import date


def int2date(argdate: int) -> date:
    """
    If you have date as an integer, use this method to obtain a datetime.date object.

    Parameters
    ----------
    argdate : int
      Date as a regular integer value (example: 20160618)

    Returns
    -------
    dateandtime.date
      A date object which corresponds to the given value `argdate`.
    """
    year = int(argdate / 10000)
    month = int((argdate % 10000) / 100)
    day = int(argdate % 100)

    return date(year, month, day)


print(int2date(20160618))

The code above produces the expected 2016-06-18.

 Try this:- SELECT Case WHEN COLUMNNAME=0 THEN 'sex'
              ELSE WHEN COLUMNNAME=1 THEN 'Female' END AS YOURGRIDCOLUMNNAME FROM YOURTABLENAME

Use the reflect package:

Package reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types. The typical use is to take a value with static type interface{} and extract its dynamic type information by calling TypeOf, which returns a Type.

package main

import (
    "fmt"
    "reflect"
)

func main() {
    b := true
    s := ""
    n := 1
    f := 1.0
    a := []string{"foo", "bar", "baz"}

    fmt.Println(reflect.TypeOf(b))
    fmt.Println(reflect.TypeOf(s))
    fmt.Println(reflect.TypeOf(n))
    fmt.Println(reflect.TypeOf(f))
    fmt.Println(reflect.TypeOf(a))
}

Produces:

bool
string
int
float64
[]string

Playground

Example using ValueOf(i interface{}).Kind():

package main

import (
    "fmt"
    "reflect"
)

func main() {
    b := true
    s := ""
    n := 1
    f := 1.0
    a := []string{"foo", "bar", "baz"}

    fmt.Println(reflect.ValueOf(b).Kind())
    fmt.Println(reflect.ValueOf(s).Kind())
    fmt.Println(reflect.ValueOf(n).Kind())
    fmt.Println(reflect.ValueOf(f).Kind())
    fmt.Println(reflect.ValueOf(a).Index(0).Kind()) // For slices and strings
}

Produces:

I made this method that could help. It is not a big deal but it works:

def colorize(text, color = "default", bgColor = "default")
    colors = {"default" => "38","black" => "30","red" => "31","green" => "32","brown" => "33", "blue" => "34", "purple" => "35",
     "cyan" => "36", "gray" => "37", "dark gray" => "1;30", "light red" => "1;31", "light green" => "1;32", "yellow" => "1;33",
      "light blue" => "1;34", "light purple" => "1;35", "light cyan" => "1;36", "white" => "1;37"}
    bgColors = {"default" => "0", "black" => "40", "red" => "41", "green" => "42", "brown" => "43", "blue" => "44",
     "purple" => "45", "cyan" => "46", "gray" => "47", "dark gray" => "100", "light red" => "101", "light green" => "102",
     "yellow" => "103", "light blue" => "104", "light purple" => "105", "light cyan" => "106", "white" => "107"}
    color_code = colors[color]
    bgColor_code = bgColors[bgColor]
    return "\033[#{bgColor_code};#{color_code}m#{text}\033[0m"
end

Here's how to use it:

puts "#{colorize("Hello World")}"
puts "#{colorize("Hello World", "yellow")}"
puts "#{colorize("Hello World", "white","light red")}"

Possible improvements could be:

• colors and bgColors are being defined each time the method is called and they don't change.
• Add other options like bold, underline, dim, etc.

This method does not work for p, as p does an inspect to its argument. For example:

p "#{colorize("Hello World")}"

will show "\e[0;38mHello World\e[0m"

I tested it with puts, print, and the Logger gem, and it works fine.

I improved this and made a class so colors and bgColors are class constants and colorize is a class method:

EDIT: Better code style, defined constants instead of class variables, using symbols instead of strings, added more options like, bold, italics, etc.

                light_blue: '1;34', light_purple: '1;35', light_cyan: '1;36', white: '1;37' }.freeze
    BG_COLOURS = { default: '0', black: '40', red: '41', green: '42', brown: '43', blue: '44',
                   purple: '45', cyan: '46', gray: '47', dark_gray: '100', light_red: '101', light_green: '102',
                   yellow: '103', light_blue: '104', light_purple: '105', light_cyan: '106', white: '107' }.freeze

    FONT_OPTIONS = { bold: '1', dim: '2', italic: '3', underline: '4', reverse: '7', hidden: '8' }.freeze

    def self.colorize(text, colour = :default, bg_colour = :default, **options)
        colour_code = COLOURS[colour]
        bg_colour_code = BG_COLOURS[bg_colour]
        font_options = options.select { |k, v| v && FONT_OPTIONS.key?(k) }.keys
        font_options = font_options.map { |e| FONT_OPTIONS[e] }.join(';').squeeze
        return "\e[#{bg_colour_code};#{font_options};#{colour_code}m#{text}\e[0m".squeeze(';')
    end
end

You can use it by doing:

Colorizator.colorize "Hello World", :gray, :white
Colorizator.colorize "Hello World", :light_blue, bold: true
Colorizator.colorize "Hello World", :light_blue, :white, bold: true, underline: true

Get input1 data to send them to input2 immediately

<div>
<label>Input1</label>
 <input type="text" id="input1" value="">
</div>

</br>
<label>Input2</label>
<input type="text" id="input2" value="">

<script type="text/javascript">
        $(document).ready(function () {
            $("#input1").keyup(function () {
                var value = $(this).val();
                $("#input2").val(value);
            });
        });
</script>

I think you want something along the line of:

Parent:

<Editor name={this.state.fileData} />

Editor:

var Editor = React.createClass({
  displayName: 'Editor',
  propTypes: {
    name: React.PropTypes.string.isRequired
  },
  getInitialState: function() { 
    return {
      value: this.props.name
    };
  },
  handleChange: function(event) {
    this.setState({value: event.target.value});
  },
  render: function() {
    return (
      <form id="noter-save-form" method="POST">
        <textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
        <input type="submit" value="Save" />
      </form>
    );
  }
});

This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html

Update for React 16.8:

import React, { useState } from 'react';

const Editor = (props) => {
    const [value, setValue] = useState(props.name);

    const handleChange = (event) => {
        setValue(event.target.value);
    };

    return (
        <form id="noter-save-form" method="POST">
            <textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
            <input type="submit" value="Save" />
        </form>
    );
}

Editor.propTypes = {
    name: PropTypes.string.isRequired
};

TLDR; The best I can come up with is this: (Depending on your use case, there are a number of ways to optimize this function.)

function arrayIndexExists(array, index){
    if ( typeof index !== 'number' && index === parseInt(index).toString()) {
        index = parseInt(index);
    } else {
        return false;//to avoid checking typeof again
    }
    return typeof index === 'number' && index % 1===0 && index >= 0 && array.hasOwnKey(index);
}

The other answer's examples get close and will work for some (probably most) purposes, but are technically quite incorrect for reasons I explain below.

Javascript arrays only use 'numerical' keys. When you set an "associative key" on an array, you are actually setting a property on that array object, not an element of that array. For example, this means that the "associative key" will not be iterated over when using Array.forEach() and will not be included when calculating Array.length. (The exception for this is strings like '0' will resolve to an element of the array, but strings like ' 0' won't.)

Additionally, checking array element or object property that doesn't exist does evaluate as undefined, but that doesn't actually tell you that the array element or object property hasn't been set yet. For example, undefined is also the result you get by calling a function that doesn't terminate with a return statement. This could lead to some strange errors and difficulty debugging code.

This can be confusing, but can be explored very easily using your browser's javascript console. (I used chrome, each comment indicates the evaluated value of the line before it.);

var foo = new Array();
foo;
//[]
foo.length;
//0
foo['bar'] = 'bar';
//"bar"
foo;
//[]
foo.length;
//0
foo.bar;
//"bar"

This shows that associative keys are not used to access elements in the array, but for properties of the object.

foo[0] = 0;
//0
foo;
//[0]
foo.length;
//1
foo[2] = undefined
//undefined
typeof foo[2]
//"undefined"
foo.length
//3

This shows that checking typeof doesn't allow you to see if an element has been set.

var foo = new Array();
//undefined
foo;
//[]
foo[0] = 0;
//0
foo['0']
//0
foo[' 0']
//undefined

This shows the exception I mentioned above and why you can't just use parseInt();

If you want to use associative arrays, you are better off using simple objects as other answers have recommended.

I find the Code Metrics and Dependency Structure Matrix add-ins for Reflector very useful.

In addition to @JBNizet's answer, my general use case for ifPresent is to combine .isPresent() and .get():

Old way:

Optional opt = getIntOptional();
if(opt.isPresent()) {
    Integer value = opt.get();
    // do something with value
}

New way:

Optional opt = getIntOptional();
opt.ifPresent(value -> {
    // do something with value
})

This, to me, is more intuitive.

You need to initialize the list first:

protected List<string> list = new List<string>();

Actually, there are different ways to downcast float to int, depending on the result you want to achieve: (for int i, float f)

• round (the closest integer to given float)

  i = Math.round(f);
    f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  3
    f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -3
  

  note: this is, by contract, equal to (int) Math.floor(f + 0.5f)

• truncate (i.e. drop everything after the decimal dot)

  i = (int) f;
    f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  2
    f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2
  

• ceil/floor (an integer always bigger/smaller than a given value if it has any fractional part)

  i = (int) Math.ceil(f);
    f =  2.0 -> i =  2 ; f =  2.22 -> i =  3 ; f =  2.68 -> i =  3
    f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2
  
  i = (int) Math.floor(f);
    f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  2
    f = -2.0 -> i = -2 ; f = -2.22 -> i = -3 ; f = -2.68 -> i = -3
  

For rounding positive values, you can also just use (int)(f + 0.5), which works exactly as Math.Round in those cases (as per doc).

You can also use Math.rint(f) to do the rounding to the nearest even integer; it's arguably useful if you expect to deal with a lot of floats with fractional part strictly equal to .5 (note the possible IEEE rounding issues), and want to keep the average of the set in place; you'll introduce another bias, where even numbers will be more common than odd, though.

Please use:

logging.level.org.hibernate.type=TRACE
spring.jpa.show-sql=true

for the line you wrote

var g = $('<%=Label1.ClientID%>').val(); // Also I tried .text() and .html()

you missed adding #. it should be like this

var g = $('#<%=Label1.ClientID%>').text();

also I do not prefer using this method

that's because if you are calling a control in master or nested master page or if you are calling a control in page from master. Also controls in Repeater. regardless the MVC. this will cause problems.

you should ALWAYS call the ID of the control directly. like this

$('#ControlID')

this is simple and clear. but do not forget to set

ClientIDMode="Static"

in your controls to remain with same ID name after render. that's because ASP.net will modify the ID name in HTML rendered file in some contexts i.e. the page is for Master page the control name will be ConetentPlaceholderName_controlID

I hope it clears the question Good Luck

Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:

CSS:

.div-wrapper {
    position: relative;
    height: 300px;
    width: 300px;
}

.div-wrapper img {
    position: absolute;
    left: 0;
    bottom: 0;
}

HTML:

<div class="div-wrapper">
    <img src="blah.png"/>
</div>

Now the image sits at the bottom of the div.

I see some other answers have given the alternative, I personally think that intuitively you're doing the right thing ;). Sorry, at devoxx where several speakers have been ranting about this sort of thing.

That's why I personally use Apache's HTTPClient/HttpCore libraries to do this sort of work, I find their API to be easier to use than Java's native HTTP support. YMMV of course!

This was killing me as well, I must have re-installed visual studios a thousand times before Stack Overflow helped me! First is began with a Windows update problem While installing Visual Studio 2015 the Update flagged me that it needed - the update KB2919355. Went to the Windows update and saw several failed updates. No matter how I tried did not work. The Error code that were cited was 80070543 did some research found nothing worked until I encountered this advice http://www.dell.com/support/article/us/en/04/SLN293803/en Having followed those instructions did the Windows update again and it worked. Went back to to do the Visual Studios update got the same error again! So I decided to research KB2919355 and was frustrated until I found this site http://www.eightforums.com/windows-updates-activation/45441-update-kb2919355-finally-successful-after-multiple-fails.html

followed the instruction precisely about loading other updates and they worked. KB2919355 was finally updated so I tried again and a different error came up involving language packs. “Fatal Installation error”. After going through a series of frustrating reinstallations, uninstallations light broke through of the advice of that came this (the above) Stack Overflow entry “repairing the C++ Redistributables” which involves: Going to Start -> Control Panel -> Programs and Features Right mouse-clicks on each the redistributables (from the bottom up) and click repair for all. If any ask for a “Restart” do it immediately right then and there! Then I did the Visual Studio installations….finally after days and days of trying….it worked.

It will work.

Use reference wherever you can, pointers wherever you must.

Avoid pointers until you can't.

The reason is that pointers make things harder to follow/read, less safe and far more dangerous manipulations than any other constructs.

So the rule of thumb is to use pointers only if there is no other choice.

For example, returning a pointer to an object is a valid option when the function can return nullptr in some cases and it is assumed it will. That said, a better option would be to use something similar to std::optional (requires C++17; before that, there's boost::optional).

Another example is to use pointers to raw memory for specific memory manipulations. That should be hidden and localized in very narrow parts of the code, to help limit the dangerous parts of the whole code base.

In your example, there is no point in using a pointer as argument because:

1. if you provide nullptr as the argument, you're going in undefined-behaviour-land;
2. the reference attribute version doesn't allow (without easy to spot tricks) the problem with 1.
3. the reference attribute version is simpler to understand for the user: you have to provide a valid object, not something that could be null.

If the behaviour of the function would have to work with or without a given object, then using a pointer as attribute suggests that you can pass nullptr as the argument and it is fine for the function. That's kind of a contract between the user and the implementation.

We can pretend they are filenames and remove extensions:

tools::file_path_sans_ext(a)
# [1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"

for me this how I solve it:

• go to the build path of the current project

under Libraries

• select the "JRE System Library [jdk1.8xxx]"
• click edit
• and select either "Workspace default JRE(jdk1.8xx)" OR Alternate JRE
• Click finish
• Click OK

Note: make sure that in Eclipse / Preferences (NOT the project) / Java / Installed JRE ,that the jdk points to the JDK folder not the JRE C:\Program Files\Java\jdk1.8.0_74

In httpd.conf

1. Make sure these are loaded:

LoadModule headers_module modules/mod_headers.so

LoadModule rewrite_module modules/mod_rewrite.so

2. In the target directory:

<Directory "**/usr/local/PATH**">
    AllowOverride None
    Require all granted

    Header always set Access-Control-Allow-Origin "*"
    Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
    Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"
    Header always set Access-Control-Expose-Headers "Content-Security-Policy, Location"
    Header always set Access-Control-Max-Age "600"

    RewriteEngine On
    RewriteCond %{REQUEST_METHOD} OPTIONS
    RewriteRule ^(.*)$ $1 [R=200,L]

</Directory>

If running outside container, you may need to restart apache service.

It is possible and Spring MVC 3 does it, but I didn't take the time to see exactly how.

The matching of method parameter names to URI Template variable names can only be done if your code is compiled with debugging enabled. If you do have not debugging enabled, you must specify the name of the URI Template variable name in the @PathVariable annotation in order to bind the resolved value of the variable name to a method parameter. For example:

Answers suggesting to disable CURLOPT_SSL_VERIFYPEER should not be accepted. The question is "Why doesn't it work with cURL", and as correctly pointed out by Martijn Hols, it is dangerous.

The error is probably caused by not having an up-to-date bundle of CA root certificates. This is typically a text file with a bunch of cryptographic signatures that curl uses to verify a host’s SSL certificate.

You need to make sure that your installation of PHP has one of these files, and that it’s up to date (otherwise download one here: http://curl.haxx.se/docs/caextract.html).

Then set in php.ini:

curl.cainfo = <absolute_path_to> cacert.pem

If you are setting it at runtime, use:

curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/cacert.pem");

as a few people mentioned scala.io.Source is best to be avoided due to connection leaks.

Probably scalax and pure java libs like commons-io are the best options until the new incubator project (ie scala-io) gets merged.

I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled, it may have left a temp file e.g. default~ (watch the ~).

Depending on your editor, the file could be named .save or something like it. Just run $ ls -lah to see which files are unintended to be there and remove them (Thanks @Tisch for this).

Delete this file, and it will solve your problem.

suppose you have a nested object, like

var obj = {"parent": {"child": {....}}}

If you passed the reference of the complete object, like

[wholeObj] = "obj"

In that case, you can't detect the changes in the child objects, so to overcome this problem you can also pass the reference of the child object through another property, like

[wholeObj] = "obj" [childObj] = "obj.parent.child"

So you can also detect the changes from the child objects too.

ngOnChanges(changes: SimpleChanges) { 
    if (changes.childObj) {// your logic here}
}

var groupedCustomerList = CustomerList.GroupBy(u => u.GroupID)
                                      .Select(grp =>new { GroupID =grp.Key, CustomerList = grp.ToList()})
                                      .ToList();

For completeness and future searches:

It's a matter of how cURL manages the buffer, the buffer disables the output stream with the -N option.

Example: curl -s -N "URL" | grep -q Welcome

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

This appears to be a limitation in git-bash. The recommendation to use winpty python.exe worked for me. See Python not working in the command line of git bash for additional information.

WARNING: Security researches have found several poisoned packages on PyPI, including a package named urllib, which will 'phone home' when installed. If you used pip install urllib some time after June 2017, remove that package as soon as possible.

You can't, and you don't need to.

urllib2 is the name of the library included in Python 2. You can use the urllib.request library included with Python 3, instead. The urllib.request library works the same way urllib2 works in Python 2. Because it is already included you don't need to install it.

If you are following a tutorial that tells you to use urllib2 then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2 comes with that version.

Alternatively, install the requests library for a higher-level and easier to use API. It'll work on both Python 2 and 3.

The following will return you the "a" letter:

$a = array_shift(explode('.', 'a.b'));

Easiest and Simplest method of solving this problem is using re

import re

search_list = ['one', 'two', 'there']
long_string = 'some one long two phrase three'
if re.compile('|'.join(search_list),re.IGNORECASE).search(long_string): #re.IGNORECASE is used to ignore case
    # Do Something if word is present
else:
    # Do Something else if word is not present

If bringing existing Visual Studio 2015 solution into Visual Studio 2017 and you want to build it with c++17 native compiler, you should first Retarget the solution/projects to v141 , THEN the dropdown will appear as described above ( Configuration Properties -> C/C++ -> Language -> Language Standard)

With the later spring-boot releases switching to Hikari can be done entirely in configuration. I'm using 1.5.6.RELEASE and this approach works.

build.gradle:

compile "com.zaxxer:HikariCP:2.7.3"

application YAML

spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      idleTimeout: 60000
      minimumIdle: 2
      maximumPoolSize: 20
      connectionTimeout: 30000
      poolName: MyPoolName
      connectionTestQuery: SELECT 1

Change connectionTestQuery to suit your underlying DB. That's it, no code required.

Rand() does generate a uniform distribution of random numbers between 0 and 1, but the norminv (or norm.inv) function is taking the uniform distributed Rand() as an input to generate the normally distributed sample set.
