git reset HEAD

Should do it. If you don't have any uncommitted changes that you care about, then

git reset --hard HEAD

should forcibly reset everything to your last commit. If you do have uncommitted changes, but the first command doesn't work, then save your uncommitted changes with git stash:

git stash
git reset --hard HEAD
git stash pop

I don't think the accepted answer works anymore. According to Microsoft here, here, and here, asp.net-5 has been re-branded to ASP.Net Core. It looks like they've taken down the asp.net-5 templates from the general ASP.Net Web Application project type. But now there's a new project type of ASP.Net Core Web Application. I don't see an MVC template for this project type, but I don't think the Core framework has been completely released yet.

You can use SEPARATOR and ORDER BY inside the GROUP_CONCAT function in this way:

SELECT li.client_id, group_concat(li.percentage ORDER BY li.views ASC SEPARATOR ',') 
AS views, group_concat(li.percentage ORDER BY li.percentage ASC SEPARATOR ',') FROM li
GROUP BY client_id;

select * from Reference where reference_dt = DateAdd(month,1,another_date_reference)

As far I know, every concatenation implies a memory reallocation. So the problem is not the operator used to do it, the solution is to reduce the number of concatenations. For example do the concatenations outside of the iteration structures when you can.

The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.

The cleanest and simplest way to do this:

First some CSS:

div.image-wrapper {
    height: 230px; /* Suggestive number; pick your own height as desired */
    position: relative;
    overflow: hidden; /* This will do the magic */
    width: 300px; /* Pick an appropriate width as desired, unless you already use a grid, in that case use 100% */
}
img {
    width: 100%;
    position: absolute;
    left: 0;
    top: 0;
    height: auto;
}

The HTML:

<div class="image-wrapper">
  <img src="yourSource.jpg">
</div>

This should do the trick!

Here is another sample code to use BackgroundWorker to update ProgressBar, just add BackgroundWorker and Progressbar to your main form and use below code:

public partial class Form1 : Form
{
    public Form1()
    {
      InitializeComponent();
      Shown += new EventHandler(Form1_Shown);

    // To report progress from the background worker we need to set this property
    backgroundWorker1.WorkerReportsProgress = true;
    // This event will be raised on the worker thread when the worker starts
    backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
    // This event will be raised when we call ReportProgress
    backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);
}
void Form1_Shown(object sender, EventArgs e)
{
    // Start the background worker
    backgroundWorker1.RunWorkerAsync();
}
// On worker thread so do our thing!
void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    // Your background task goes here
    for (int i = 0; i <= 100; i++)
    {
        // Report progress to 'UI' thread
        backgroundWorker1.ReportProgress(i);
        // Simulate long task
        System.Threading.Thread.Sleep(100);
    }
}
// Back on the 'UI' thread so we can update the progress bar
void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    // The progress percentage is a property of e
    progressBar1.Value = e.ProgressPercentage;
}
}

refrence:from codeproject

You can use \blacksquare ¦:

When creating TeX, Knuth provided the symbol ¦ (solid black square), also called by mathematicians tombstone or Halmos symbol (after Paul Halmos, who pioneered its use as an equivalent of Q.E.D.). The tombstone is sometimes open: ? (hollow black square).

It is a conditional statement.

If browser supprts e.keyCode then take e.keyCode else e.charCode.

It is similar to

var code = event.keyCode || event.charCode

event.keyCode: Returns the Unicode value of a non-character key in a keypress event or any key in any other type of keyboard event.

event.charCode: Returns the Unicode value of a character key pressed during a keypress event.

If you want to restrict user to give blank space in the name just create a if statement and give the condition. like I did:

$j('#fragment_key').bind({
    keypress: function(e){
        var key = e.keyCode;
    var character = String.fromCharCode(key); 
    if(character.match( /[' ']/)) {
        alert("Blank space is not allowed in the Name");
        return false;
        }
    }
});

• create a JQuery function .
• this is key press event.
• Initialize a variable.
• Give condition to match the character
• show a alert message for your matched condition.

In View

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

JS:

In side controller

 $scope.boxModel = 600;

Improvement of @ravi404, in case your autoincrement offset IS NOT 1 :

SELECT (`auto_increment`-1) + IFNULL(@@auto_increment_offset,1) 
FROM INFORMATION_SCHEMA.TABLES
WHERE table_name = your_table_name
AND table_schema = DATABASE( );

(auto_increment-1) : db engine seems to alwaus consider an offset of 1. So you need to ditch this assumption, then add the optional value of @@auto_increment_offset, or default to 1 : IFNULL(@@auto_increment_offset,1)

A more production-ready way to handle this is to actually ensure that name is present. Assuming this is a minimal example of a larger project that a group of people are involved with, you don't know how getPerson will change in the future.

if (!person.name) {
    throw new Error("Unexpected error: Missing name");
}

let name1: string = person.name;

Alternatively, you can type name1 as string | undefined, and handle cases of undefined further down. However, it's typically better to handle unexpected errors earlier on.

You can also let TypeScript infer the type by omitting the explicit type: let name1 = person.name This will still prevent name1 from being reassigned as a number, for example.

Eclipse has a search feature in the top left box of the Preferences. Type in 'line numbers' in that search box, and presto...

For a 2021 Solution in dotnet core, you can fix this error by right-clicking the project in Solution Explorer, and choosing 'Edit Project File'.

On the Debug Tab, at the bottom, you can directly configure the desired port and whether to use SSL or not.

Changes here need to be saved with Control+S. Once that's done, you can launch the project and confirm it fixed your issue, no having to delete IISFolders or anything else suggested here.

Get the value for an associative array property when the property name is an integer:

Starting with an associative array where the property names are integers:

var categories = [
    {"1": "Category 1"},
    {"2": "Category 2"},
    {"3": "Category 3"},
    {"4": "Category 4"}
];

Push items to the array:

categories.push({"2300": "Category 2300"});
categories.push({"2301": "Category 2301"});

Loop through the array and do something with the property value.

for (var i = 0; i < categories.length; i++) {
    for (var categoryid in categories[i]) {
        var category = categories[i][categoryid];
        // Log progress to the console
        console.log(categoryid + ": " + category);
        //  ... do something
    }
}

Console output should look like this:

1: Category 1
2: Category 2
3: Category 3
4: Category 4
2300: Category 2300
2301: Category 2301

As you can see, you can get around the associative array limitation and have a property name be an integer.

NOTE: The associative array in my example is the JSON content you would have if you serialized a Dictionary<string, string>[] object.

PUT and PATCH methods are similar in nature, but there is a key difference.

PUT - in PUT request, the enclosed entity would be considered as the modified version of a resource which residing on server and it would be replaced by this modified entity.

PATCH - in PATCH request, enclosed entity contains the set of instructions that how the entity which residing on server, would be modified to produce a newer version.

Go to Control Panel\User Accounts\Credential Manager and select Windows Credential then remove account of git.

Add client_max_body_size

Now that you are editing the file you need to add the line into the server block, like so;

server {
    client_max_body_size 8M;

    //other lines...
}

If you are hosting multiple sites add it to the http context like so;

http {
    client_max_body_size 8M;

    //other lines...
}

And also update the upload_max_filesize in your php.ini file so that you can upload files of the same size.

Saving in Vi

Once you are done you need to save, this can be done in vi with pressing esc key and typing :wq and returning.

Restarting Nginx and PHP

Now you need to restart nginx and php to reload the configs. This can be done using the following commands;

sudo service nginx restart
sudo service php5-fpm restart

Or whatever your php service is called.

With recent git versions you can git add -N the file (or --intent-to-add), which adds a zero-length blob to the index at that location. The upshot is that your "untracked" file now becomes a modification to add all the content to this zero-length file, and that shows up in the "git diff" output.

git diff

echo "this is a new file" > new.txt
git diff

git add -N new.txt
git diff
diff --git a/new.txt b/new.txt
index e69de29..3b2aed8 100644
--- a/new.txt
+++ b/new.txt
@@ -0,0 +1 @@
+this is a new file

Sadly, as pointed out, you can't git stash while you have an --intent-to-add file pending like this. Although if you need to stash, you just add the new files and then stash them. Or you can use the emulation workaround:

git update-index --add --cacheinfo \
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 new.txt

(setting up an alias is your friend here).

Immutable Object's state cannot be altered.

for example String.

String str= "abc";//a object of string is created
str  = str + "def";// a new object of string is created and assigned to str

As others have said: return value, not out param.

May I recommend to you the book "Framework Design Guidelines" (2nd ed)? Pages 184-185 cover the reasons for avoiding out params. The whole book will steer you in the right direction on all sorts of .NET coding issues.

Allied with Framework Design Guidelines is the use of the static analysis tool, FxCop. You'll find this on Microsoft's sites as a free download. Run this on your compiled code and see what it says. If it complains about hundreds and hundreds of things... don't panic! Look calmly and carefully at what it says about each and every case. Don't rush to fix things ASAP. Learn from what it is telling you. You will be put on the road to mastery.

There are probably less than 20 entries in your xml.

change the code to this

for ($i=0;$i< sizeof($xml->entry); $i++)
...

Here's my suboptimal solution, using a Bash shell script:

#!/bin/bash
# First, rename all folders
for f in `find . -depth ! -name CVS -type d`; do
   g=`dirname "$f"`/`basename "$f" | tr '[A-Z]' '[a-z]'`
   if [ "xxx$f" != "xxx$g" ]; then
      echo "Renaming folder $f"
      mv -f "$f" "$g"
   fi
done

# Now, rename all files
for f in `find . ! -type d`; do
   g=`dirname "$f"`/`basename "$f" | tr '[A-Z]' '[a-z]'`
   if [ "xxx$f" != "xxx$g" ]; then
      echo "Renaming file $f"
      mv -f "$f" "$g"
   fi
done

Folders are all renamed correctly, and mv isn't asking questions when permissions don't match, and CVS folders are not renamed (CVS control files inside that folder are still renamed, unfortunately).

Since "find -depth" and "find | sort -r" both return the folder list in a usable order for renaming, I preferred using "-depth" for searching folders.

Have a look at Knockout-Validation which cleanly setups and uses what's described in the knockout documentation. Under: Live Example 1: Forcing input to be numeric

You can see it live in Fiddle

UPDATE: the fiddle has been updated to use the latest KO 2.0.3 and ko.validation 1.0.2 using the cloudfare CDN urls

To setup ko.validation:

ko.validation.rules.pattern.message = 'Invalid.';

ko.validation.configure({
    registerExtenders: true,
    messagesOnModified: true,
    insertMessages: true,
    parseInputAttributes: true,
    messageTemplate: null
});

To setup validation rules, use extenders. For instance:

var viewModel = {
    firstName: ko.observable().extend({ minLength: 2, maxLength: 10 }),
    lastName: ko.observable().extend({ required: true }),
    emailAddress: ko.observable().extend({  // custom message
        required: { message: 'Please supply your email address.' }
    })
};

You must check this: Docblock Comment standards

In case you have a multi-module project :

let us say your module structure is

root-module
 -> a-module
 -> b-module

and the test(testToRun) you are looking to run is in b-module, with full path : com.xyz.b.module.TestClass.testToRun

As here you are interested to run the test in b-module, so you should see the tasks available for b-module.

./gradlew :b-module:tasks

The above command will list all tasks in b-module with description. And in ideal case, you will have a task named test to run the unit tests in that module.

./gradlew :b-module:test

Now, you have reached the point for running all the tests in b-module, finally you can pass a parameter to the above task to run tests which matches the certain path pattern

./gradlew :b-module:test --tests "com.xyz.b.module.TestClass.testToRun"

Now, instead of this if you run

./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"

It will run the test task for both module a and b, which might result in failure as there is nothing matching the above pattern in a-module.

If you are trying to do something similar to the Google search page when open in Chrome, (where certain events are triggered when you 'focus' on the page), then the hover() event may help.

$(window).hover(function() {
  // code here...
});

Use the @Input() decorator in your child component to allow the parent to bind to this input.

In the child component you declare it as is :

@Input() myInputName: myType

To bind a property from parent to a child you must add in you template the binding brackets and the name of your input between them.

Example :

<my-child-component [myChildInputName]="myParentVar"></my-child-component>

But beware, objects are passed as a reference, so if the object is updated in the child the parent's var will be too updated. This might lead to some unwanted behaviour sometime. With primary types the value is copied.

I wrote this a couple years ago but i believe it still works:

if(navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.match(/iPhone/i) || (navigator.userAgent.match(/iPod/i))) 

    {

        alert("Ipod or Iphone");

    }

else if (navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.match(/iPad/i))  

    {

        alert("Ipad");

    }

else if (navigator.vendor != null && navigator.vendor.match(/Apple Computer, Inc./) && navigator.userAgent.indexOf('Safari') != -1)

    {

        alert("Safari");

    }

else if (navigator.vendor == null || navigator.vendor != null)

    {

        alert("Not Apple Based Browser");

    }

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID

The precedent answers show you how to handle bit checks, but more often then not, it is all about flags encoded in an integer, which is not well defined in any of the precedent cases.

In a typical scenario, flags are defined as integers themselves, with a bit to 1 for the specific bit it refers to. In the example hereafter, you can check if the integer has ANY flag from a list of flags (multiple error flags concatenated) or if EVERY flag is in the integer (multiple success flags concatenated).

Following an example of how to handle flags in an integer.

Live example available here: https://rextester.com/XIKE82408

//g++  7.4.0

#include <iostream>
#include <stdint.h>

inline bool any_flag_present(unsigned int value, unsigned int flags) {
    return bool(value & flags);
}

inline bool all_flags_present(unsigned int value, unsigned int flags) {
    return (value & flags) == flags;
}

enum: unsigned int {
    ERROR_1 = 1U,
    ERROR_2 = 2U, // or 0b10
    ERROR_3 = 4U, // or 0b100
    SUCCESS_1 = 8U,
    SUCCESS_2 = 16U,
    OTHER_FLAG = 32U,
};

int main(void)
{
    unsigned int value = 0b101011; // ERROR_1, ERROR_2, SUCCESS_1, OTHER_FLAG
    unsigned int all_error_flags = ERROR_1 | ERROR_2 | ERROR_3;
    unsigned int all_success_flags = SUCCESS_1 | SUCCESS_2;
    
    std::cout << "Was there at least one error: " << any_flag_present(value, all_error_flags) << std::endl;
    std::cout << "Are all success flags enabled: " << all_flags_present(value, all_success_flags) << std::endl;
    std::cout << "Is the other flag enabled with eror 1: " << all_flags_present(value, ERROR_1 | OTHER_FLAG) << std::endl;
    return 0;
}

I'd use iloc, which takes a row/column slice, both based on integer position and following normal python syntax. If you want every 5th row:

df.iloc[::5, :]

You can use moment.js: http://momentjs.com/

var m = moment().format("DD/MM/YYYY");_x000D_
_x000D_
document.write(m);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.14.1/moment.min.js"></script>

DiskFileUpload upload=new DiskFileUpload();

From this object you have to get file items and fields then yo can store into server like followed:

String loc="./webapps/prjct name/server folder/"+contentid+extension;
File uploadFile=new File(loc);
item.write(uploadFile);

Instead of using URI segments you should do this:

$this->router->fetch_class(); // class = controller
$this->router->fetch_method();

That way you know you are always using the correct values even if you are behind a routed URL, in a sub-domain, etc.

Easiest Way: Connect to Sqlite3 via ADB Shell

I haven't found any way to do that in Android Studio, but I access the db with a remote shell instead of pulling the file each time.

Find all info here: http://developer.android.com/tools/help/sqlite3.html

1- Go to your platform-tools folder in a command prompt

2- Enter the command adb devices to get the list of your devices

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb devices
List of devices attached
emulator-xxxx   device

3- Connect a shell to your device:

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb -s emulator-xxxx shell

4a- You can bypass this step on rooted device

run-as <your-package-name> 

4b- Navigate to the folder containing your db file:

cd data/data/<your-package-name>/databases/

5- run sqlite3 to connect to your db:

sqlite3 <your-db-name>.db

6- run sqlite3 commands that you like eg:

Select * from table1 where ...;

Note: Find more commands to run below.

SQLite cheatsheet

There are a few steps to see the tables in an SQLite database:

1. List the tables in your database:

   .tables
   

2. List how the table looks:

   .schema tablename
   

3. Print the entire table:

   SELECT * FROM tablename;
   

4. List all of the available SQLite prompt commands:

   .help
   

This helped me to call API that was using cookie authentication. I have passed authorization in header like this:

request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));

complete code:

// utility method to read the cookie value:
        public static string ReadCookie(string cookieName)
        {
            var cookies = HttpContext.Current.Request.Cookies;
            var cookie = cookies.Get(cookieName);
            if (cookie != null)
                return cookie.Value;
            return null;
        }

// using statements where you are creating your webclient

using (var webClient = new WebClient()) {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
      HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
      request.Method = "POST";
      request.ContentType = "application/json";                        
      request.ContentLength = requestData.Length;
      request.ContentType = "application/json";
      request.Expect = "application/json";
      request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
      request.GetRequestStream().Write(requestData, 0, requestData.Length);

      using (var response = (HttpWebResponse)request.GetResponse()) {
         var reader = new StreamReader(response.GetResponseStream());
         var objText = reader.ReadToEnd(); // objText will have the value
      }
}

Yes.. but awkward. Link

The problem is that the base class foo has no parameterless constructor. So you must call constructor of the base class with parameters from constructor of the derived class:

public bar(int a, int b) : base(a, b)
{
    c = a * b;
}

I suspect you are running Android 6.0 Marshmallow (API 23) or later. If this is the case, you must implement runtime permissions before you try to read/write external storage.

fairly simple if you use stored procedures:

call insert_user_and_profile('f00','http://www.f00.com');

full script:

drop table if exists users;
create table users
(
user_id int unsigned not null auto_increment primary key,
username varchar(32) unique not null
)
engine=innodb;

drop table if exists user_profile;
create table user_profile
(
profile_id int unsigned not null auto_increment primary key,
user_id int unsigned not null,
homepage varchar(255) not null,
key (user_id)
)
engine=innodb;

drop procedure if exists insert_user_and_profile;

delimiter #

create procedure insert_user_and_profile
(
in p_username varchar(32),
in p_homepage varchar(255)
)
begin
declare v_user_id int unsigned default 0;

insert into users (username) values (p_username);
set v_user_id = last_insert_id(); -- save the newly created user_id

insert into user_profile (user_id, homepage) values (v_user_id, p_homepage);

end#

delimiter ;

call insert_user_and_profile('f00','http://www.f00.com');

select * from users;
select * from user_profile;

As others pointed out, the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install. Another option would be to use the manager application if it is installed (this is not always the case), if it's properly configured (i.e. if you have the credentials of a user assigned to the appropriate group) and if it you can access it over an insecure network like Internet (but this is very unlikely and you didn't mention any VPN access). So this leaves you with the webappdirectory.

Now, if Tomcat is installed and running on bilgin.ath.cx (as this is the machine where you uploaded the files), I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache. In that case, I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files (mod_jk?, mod_proxy?). You should either give us more details or discuss this with your hosting provider.

Update: As expected, the bilgin.ath.cx is using Apache Tomcat + Apache HTTPD + mod_jk. The configuration usually involves two files: the worker.properties file to configure the workers and the httpd.conf for Apache. Now, without seeing the current configuration, it's not easy to give a definitive answer but, basically, you may have to add a JkMount directive in Apache httpd.conf for your new webapp¹. Refer to the mod_jk documentation, it has a simple configuration example. Note that modifying httpd.conf will require access to (obviously) and proper rights and that you'll have to restart Apache after the modifications.

_{¹ I don't think you'll need to define a new worker if you are deploying to an already used Tomcat instance, especially if this sounds like Chinese for you :)}

I had the exact same problem. The problem was that Anaconda had not registered Python in the windows registry.

1) pip install pywin
2) execute this script to register Python in the windows registry
3) download the appropriate package form Corey Goldberg's answer and python will be detected

How about that?

function internalHandler(e) {
    e.preventDefault(); // required in some browsers
    e.returnValue = ""; // required in some browsers
    return "Custom message to show to the user"; // only works in old browsers
}

if (window.addEventListener) {
    window.addEventListener('beforeunload', internalHandler, true);
} else if (window.attachEvent) {
    window.attachEvent('onbeforeunload', internalHandler);
}

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Rows.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Cells.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Count

select count(*) from dbo.tablename where address_line_1 LIKE '%[\'']%' {eSCAPE'\'}

You could call it just style, but I prefer aliasing to improve readability.

At the time of writing this, the current version of Tomcat 7 (7.0.41) has a built-in CORS filter http://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#CORS_Filter

The manual uses the terms "callback" and "callable" interchangeably, however, "callback" traditionally refers to a string or array value that acts like a function pointer, referencing a function or class method for future invocation. This has allowed some elements of functional programming since PHP 4. The flavors are:

$cb1 = 'someGlobalFunction';
$cb2 = ['ClassName', 'someStaticMethod'];
$cb3 = [$object, 'somePublicMethod'];

// this syntax is callable since PHP 5.2.3 but a string containing it
// cannot be called directly
$cb2 = 'ClassName::someStaticMethod';
$cb2(); // fatal error

// legacy syntax for PHP 4
$cb3 = array(&$object, 'somePublicMethod');

This is a safe way to use callable values in general:

if (is_callable($cb2)) {
    // Autoloading will be invoked to load the class "ClassName" if it's not
    // yet defined, and PHP will check that the class has a method
    // "someStaticMethod". Note that is_callable() will NOT verify that the
    // method can safely be executed in static context.

    $returnValue = call_user_func($cb2, $arg1, $arg2);
}

Modern PHP versions allow the first three formats above to be invoked directly as $cb(). call_user_func and call_user_func_array support all the above.

See: http://php.net/manual/en/language.types.callable.php

Notes/Caveats:

1. If the function/class is namespaced, the string must contain the fully-qualified name. E.g. ['Vendor\Package\Foo', 'method']
2. call_user_func does not support passing non-objects by reference, so you can either use call_user_func_array or, in later PHP versions, save the callback to a var and use the direct syntax: $cb();
3. Objects with an __invoke() method (including anonymous functions) fall under the category "callable" and can be used the same way, but I personally don't associate these with the legacy "callback" term.
4. The legacy create_function() creates a global function and returns its name. It's a wrapper for eval() and anonymous functions should be used instead.

This may not be from the script end but you can use the below css and add this class to the div. This will truncate the text and also show full text on mouseover. You can add a more text and add a angular click hadler to change the class of div on cli

.ellipseContent {
    overflow: hidden;
    white-space: nowrap;
    -ms-text-overflow: ellipsis;
    text-overflow: ellipsis;
}

    .ellipseContent:hover {
        overflow: visible;
        white-space: normal;
    }

Using Https is fine, run git config --global credential.helper wincred to create a Github credential helper that stores your credentials for you. If this doesn't work, then you need to edit your config file in your .git directory and update the origin to the https url.

While in your example, int(input(...)) does the trick in any case, python-future's builtins.input is worth consideration since that makes sure your code works for both Python 2 and 3 and disables Python2's default behaviour of input trying to be "clever" about the input data type (builtins.input basically just behaves like raw_input).

You can use Path API as follow:

 var filenNme = Path.GetFileNameWithoutExtension([File Path]);

In my android device I had different flavors of the same app install. This gives me error INSTALL FAILED CONFLICTING PROVIDER. so I uninstall my all flavors of the same app. and tried

adb install -r /Users/demo-debug-92acfc5.apk

It solved my problem.

All you have to do is apply the format you want in the html helper call, ie.

@Html.TextBoxFor(m => m.RegistrationDate, "{0:dd/MM/yyyy}")

You don't need to provide the date format in the model class.

Try this:

dict = {0:{1:'a'}, 1:{2:'b'}, 2:{3:'c'}}
for (var key in dict){
  console.log( key, dict[key] );
}

0 Object { 1="a"}
1 Object { 2="b"}
2 Object { 3="c"}

I found, bizarrely, that I could fix the errors by placing the timezone declaration at the TOP of my php.ini file.

It was already in my php.ini. Twice, actually. And I was pulling my hair out because everyone was saying there must be another ini being loaded... There wasn't.

Hope this can save someone else the time/hair loss.

I don't think this is the BEST solution, but it does appear to work. Instead of using the background color, I'm going to just embed an image of the background, position it relatively and then wrap the text in a child element and position it absolute - in the centre.

There are two branches lets say

• A (Branch on which you are working)
• B (Another branch with which you want to compare)

Being in branch A you can type

git diff --color B

then this will give you a output of

The important point about this is

1. Text in green is inside present in Branch A

2. Text in red is present in Branch B

You can use the standard Python idiom, vars():

for attr, value in vars(k).items():
    print(attr, '=', value)

You can have all the different styles to datetime conversion :

https://www.w3schools.com/sql/func_sqlserver_convert.asp

This has range of values :-

CONVERT(data_type(length),expression,style)

For style values,
Choose anyone you need like I needed 106.

This happens because there are fields with the same name in more than one table, in the query, because of the joins, so you should reference the fields differently, giving names (aliases) to the tables.

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

Other answers have already explained why virtual function calls don't work as expected when called from a constructor. I'd like to instead propose another possible work around for getting polymorphic-like behavior from a base type's constructor.

By adding a template constructor to the base type such that the template argument is always deduced to be the derived type it's possible to be aware of the derived type's concrete type. From there, you can call static member functions for that derived type.

This solution does not allow non-static member functions to be called. While execution is in the base type's constructor, the derived type's constructor hasn't even had time to go through it's member initialization list. The derived type portion of the instance being created hasn't begun being initialized it. And since non-static member functions almost certainly interact with data members it would be unusual to want to call the derived type's non-static member functions from the base type's constructor.

Here is a sample implementation :

#include <iostream>
#include <string>

struct Base {
protected:
    template<class T>
    explicit Base(const T*) : class_name(T::Name())
    {
        std::cout << class_name << " created\n";
    }

public:
    Base() : class_name(Name())
    {
        std::cout << class_name << " created\n";
    }


    virtual ~Base() {
        std::cout << class_name << " destroyed\n";
    }

    static std::string Name() {
        return "Base";
    }

private:
    std::string class_name;
};


struct Derived : public Base
{   
    Derived() : Base(this) {} // `this` is used to allow Base::Base<T> to deduce T

    static std::string Name() {
        return "Derived";
    }
};

int main(int argc, const char *argv[]) {

    Derived{};  // Create and destroy a Derived
    Base{};     // Create and destroy a Base

    return 0;
}

This example should print

Derived created
Derived destroyed
Base created
Base destroyed

When a Derived is constructed, the Base constructor's behavior depends on the actual dynamic type of the object being constructed.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['62.63.141.41', 'namjoosadr.com']

and then restart your apache. in ubuntu:

/etc/init.d/apache2 restart

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

In addition to the already great and respected answers in here, I would like to expand on PHP having no setters/getters.

PHP does not have getter and setter syntax. It provides subclassed or magic methods to allow "hooking" and overriding the property lookup process, as pointed out by Dave.

Magic allows us lazy programmers to do more with less code at a time at which we are actively engaged in a project and know it intimately, but usually at the expense of readability.

Performance Every unnecessary function, that results from forcing a getter/setter-like code-architecture in PHP, involves its own memory stack-frame upon invocation and is wasting CPU cycles.

Readability: The codebase incurs bloating code-lines, which impacts code-navigation as more LOC mean more scrolling,.

Preference: Personally, as my rule of thumb, I take the failure of static code analysis as a sign to avoid going down the magical road as long as obvious long-term benefits elude me at that time.

Fallacies:

A common argument is readability. For instance that $someobject->width is easier to read than $someobject->width(). However unlike a planet's circumference or width, which can be assumed to be static, an object's instance such as $someobject, which requires a width function, likely takes a measurement of the object's instance width.
Therefore readability increases mainly because of assertive naming-schemes and not by hiding the function away that outputs a given property-value.

__get / __set uses:

• pre-validation and pre-sanitation of property values

• strings e.g.

  "
  some {mathsobj1->generatelatex} multi
  line text {mathsobj1->latexoutput}
  with lots of variables for {mathsobj1->generatelatex}
   some reason
  "
  

  In this case generatelatex would adhere to a naming scheme of actionname + methodname

• special, obvious cases

  $dnastringobj->homeobox($one_rememberable_parameter)->gattaca->findrelated()
  $dnastringobj->homeobox($one_rememberable_parameter)->gttccaatttga->findrelated()
  

Note: PHP chose not to implement getter/setter syntax. I am not claiming that getters/setter are generally bad.

Try this method then you can do every thing you want.
It is like a stack so be careful which item comes first or last.

<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="50dp" android:start="10dp" android:left="10dp">
    <shape
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">

</item>
<item android:top="90dp" android:end="60dp">
    <shape android:shape="rectangle">
        <solid android:color="#e2cc2626" />
    </shape>

<item android:start="50dp" android:bottom="20dp" android:top="120dp">

Something new to think about looking forward to Object.observe in ES7 and with data-binding in general. Consider:

var foo={
   name: "hello"
};

Object.observe(foo, function(){alert('modified');}); // bind to foo

foo={}; // You are no longer bound to foo but to an orphaned version of it
foo.name="there"; // This change will be missed by Object.observe()

So under that circumstance #2 can be the best choice.

[\W_]+

$string = preg_replace("/[\W_]+/u", '', $string);

It select all not A-Z, a-z, 0-9 and delete it.

See example here: https://regexr.com/3h1rj

This can be quite easily achieved using the ProcessStartInfo.RedirectStandardOutput property. A full sample is contained in the linked MSDN documentation; the only caveat is that you may have to redirect the standard error stream as well to see all output of your application.

Process compiler = new Process();
compiler.StartInfo.FileName = "csc.exe";
compiler.StartInfo.Arguments = "/r:System.dll /out:sample.exe stdstr.cs";
compiler.StartInfo.UseShellExecute = false;
compiler.StartInfo.RedirectStandardOutput = true;
compiler.Start();    

Console.WriteLine(compiler.StandardOutput.ReadToEnd());

compiler.WaitForExit();

If you have a list view you can do this:

1. Define a select list:

   @{
      var Acciones = new SelectList(new[]
      {
     new SelectListItem { Text = "Modificar", Value = 
      Url.Action("Edit", "Countries")},
     new SelectListItem { Text = "Detallar", Value = 
     Url.Action("Details", "Countries") },
     new SelectListItem { Text = "Eliminar", Value = 
     Url.Action("Delete", "Countries") },
    }, "Value", "Text");
   }
   

2. Use the defined SelectList, creating a diferent id for each record (remember that id of each element must be unique in a view), and finally call a javascript function for onchange event (include parameters in example url and record key):

   @Html.DropDownList("ddAcciones", Acciones, "Acciones", new { id = 
   item.CountryID, @onchange = "RealizarAccion(this.value ,id)" })
   

3. onchange function can be something as:

   @section Scripts {
   <script src="~/Scripts/jquery-1.10.2.min.js"></script>
   <script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
   
   <script type="text/javascript">
   
   function RealizarAccion(accion, country)
   {
   
       var url = accion + '/' + country;
       if (url != null && url != '') {
           window.location.href = url ;
       }
   }
   </script>
   
   @Scripts.Render("~/bundles/jqueryval")
   }
   

You can get Current timestamp in Android by trying below code

time.setText(String.valueOf(System.currentTimeMillis()));

and timeStamp to time format

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(Long.parseLong(time.getText().toString())));
time.setText(dateString);

PowerShell features a Restart-Service cmdlet, which either starts or restarts the service as appropriate.

The Restart-Service cmdlet sends a stop message and then a start message to the Windows Service Controller for a specified service. If a service was already stopped, it is started without notifying you of an error.

You can specify the services by their service names or display names, or you can use the InputObject parameter to pass an object that represents each service that you want to restart.

It is a little more foolproof than running two separate commands.

The easiest way to use it just pass either the service name or the display name directly:

Restart-Service 'Service Name'

It can be used directly from the standard cmd prompt with a command like:

powershell -command "Restart-Service 'Service Name'"

 if (true)
 {
   return View();
 }
 else
 {
   return View("another view name");
 }

When one has to scroll down a gridview to select a row, MaintainScrollPositionOnPostBack="true" will make it continue to show that row after one has selected it.

iOS 9.2.1, Xcode 7.2.1, ARC enabled

You can always append the '%' by itself without any other format specifiers in the string you are appending, like so...

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [stringTest stringByAppendingString:@"%"];
NSLog(@"%@", stringTest);

For iOS7.0+

To expand the answer to other characters that might cause you conflict you may choose to use:

- (NSString *)stringByAddingPercentEncodingWithAllowedCharacters:(NSCharacterSet *)allowedCharacters

Written out step by step it looks like this:

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [[stringTest stringByAppendingString:@"%"] 
             stringByAddingPercentEncodingWithAllowedCharacters:
             [NSCharacterSet alphanumericCharacterSet]];
stringTest = [stringTest stringByRemovingPercentEncoding];

NSLog(@"percent value of test: %@", stringTest);

Or short hand:

NSLog(@"percent value of test: %@", [[[[NSString stringWithFormat:@"%d", test] 
stringByAppendingString:@"%"] stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]] stringByRemovingPercentEncoding]);

Thanks to all the original contributors. Hope this helps. Cheers!

While setting the paste mode with paste/nopaste/pastetoggle is perfectly fine, you still have to manually enable paste mode before pasting and disable paste mode after pasting. Being the lazy person that I am, below is the best solution that I've found so far, which automatically toggles the paste mode when you paste.

Here's a little trick that uses terminal's bracketed paste mode to automatically set/unset Vim's paste mode when you paste. Put following in your .vimrc:

let &t_SI .= "\<Esc>[?2004h"
let &t_EI .= "\<Esc>[?2004l"

inoremap <special> <expr> <Esc>[200~ XTermPasteBegin()

function! XTermPasteBegin()
  set pastetoggle=<Esc>[201~
  set paste
  return ""
endfunction

Now you can paste without explicitly turning paste mode on/off - it is handled automatically for you.

You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify

My issue was that I used this URL:

https://accounts.google.com/o/oauth2/token

When I should have used this URL:

https://www.googleapis.com/oauth2/v4/token

This was testing a service account which wanted offline access to the Storage engine.

I've solved this problem by using the search function on Docker's website where '*' is a valid search that returns 200k repositories and then I crawled each invididual page. HTML parsing allows me to extract all the image names on each page.

For me it was related to the lack of virtual resources (Ram and CPU). Go to the virtual box, right click on device -> Setting and increase the value of each resource.

64-bit tools are not available on Visual C++ Express by default. To enable 64-bit tools on Visual C++ Express, install the Windows Software Development Kit (SDK) in addition to Visual C++ Express. Otherwise, an error occurs when you attempt to configure a project to target a 64-bit platform using Visual C++ Express.

ls = [x if (condition) else None for x in ls]

Using only substring() and recursion:

public String rev(String rest) {
    if (rest.equals(""))
        return "";
    return rev(rest.substring(1)) + rest.substring(0,1);
}

The short answer is that not only is static useful, it is pretty well always going to be desired.

First, note that static and constexpr are completely independent of each other. static defines the object's lifetime during execution; constexpr specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr is no longer relevant.

Every variable declared constexpr is implicitly const but const and static are almost orthogonal (except for the interaction with static const integers.)

The C++ object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if principle provided it can prove that no other such object can be observed.

That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr) array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.

On the other hand, a local static const object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.

So you should definitely use static constexpr in your example.

However, there is one case where you wouldn't want to use static constexpr. Unless a constexpr declared object is either ODR-used or declared static, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static, since static is likely to force the object to exist at runtime.

I am a beginner and may not clear syntax. To refer above information, I still not clear.

Both "arrA" & "arrB" can be accessed (print it out). However, can't get a size of "arrB".

What is a problem there?

1. Is 'char[]' incomplete type? or
2. 'sizeof' does not accept the extern variable/ label?

In my program, "arrA" & "arrB" are constant lists and fixed before to compile. I would like to use a label(let me easy to maintenance & save RAM memory).

Just add the line below to the <TextInput>

And it worked

This worked for me:

1. Create a new project
2. Create a class in it
3. Add erroneous code, let error come
4. Now go to your project
5. Go to Problems window
6. Double click on a error

It starts showing compilation errors in the code.

If you plan to create a PHP package you most likely want to put in on Packagist to make it available for other with composer. Composer has the as naming-convention to use vendorname/package-name-is-lowercase-with-hyphens.

If you plan to create a JS package you probably want to use npm. One of their naming conventions is to not permit upper case letters in the middle of your package name.

Therefore, I would recommend for PHP and JS packages to use lowercase-with-hyphens and name your packages in composer or npm identically to your package on GitHub.

Try

DecimalFormat df = new DecimalFormat("#,##0.00");

I don't want to sound too negative, but there are occasions when what you want is almost impossible without a lot of "artificial" tuning of page breaks.

If the callout falls naturally near the bottom of a page, and the figure falls on the following page, moving the figure back one page will probably displace the callout forward.

I would recommend (as far as possible, and depending on the exact size of the figures):

• Place the figures with [t] (or [h] if you must)
• Place the figures as near as possible to the "right" place (differs for [t] and [h])
• Include the figures from separate files with \input, which will make them much easier to move around when you're doing the final tuning

In my experience, this is a big eater-up of non-available time (:-)

In reply to Jon's comment, I think this is an inherently difficult problem, because the LaTeX guys are no slouches. You may like to read Frank Mittelbach's paper.

In my case, web server prevented "OPTIONS" method

innerHTML is a string representing the contents of the element.

You want to modify the element itself. Drop the .innerHTML part.

I would think the big factor would be performance. Both the web server/app code and SQL Server would cache commonly requested data in memory and you're killing your cache performance by running them in the same memory space.

Complementing @Bob Jarvis and @dmikam answer, Postgres don't perform a good plan when you don't use LATERAL, below a simulation, in both cases the query data results are the same, but the cost are very different

Table structure

CREATE TABLE ITEMS (
    N INTEGER NOT NULL,
    S TEXT NOT NULL
);

INSERT INTO ITEMS
  SELECT
    (random()*1000000)::integer AS n,
    md5(random()::text) AS s
  FROM
    generate_series(1,1000000);

CREATE INDEX N_INDEX ON ITEMS(N);

Performing JOIN with GROUP BY in subquery without LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    GROUP BY N
) I2 ON I2.N = I.N
WHERE I.N IN (243477, 997947);

The results

Merge Join  (cost=0.87..637500.40 rows=23 width=37)
  Merge Cond: (i.n = items.n)
  ->  Index Scan using n_index on items i  (cost=0.43..101.28 rows=23 width=37)
        Index Cond: (n = ANY ('{243477,997947}'::integer[]))
  ->  GroupAggregate  (cost=0.43..626631.11 rows=861418 width=12)
        Group Key: items.n
        ->  Index Only Scan using n_index on items  (cost=0.43..593016.93 rows=10000000 width=4)

Using LATERAL

EXPLAIN 
SELECT 
    I.*
FROM ITEMS I
INNER JOIN LATERAL (
    SELECT 
        COUNT(1), n
    FROM ITEMS
    WHERE N = I.N
    GROUP BY N
) I2 ON 1=1 --I2.N = I.N
WHERE I.N IN (243477, 997947);

Results

Nested Loop  (cost=9.49..1319.97 rows=276 width=37)
  ->  Bitmap Heap Scan on items i  (cost=9.06..100.20 rows=23 width=37)
        Recheck Cond: (n = ANY ('{243477,997947}'::integer[]))

My Postgres version is PostgreSQL 10.3 (Debian 10.3-1.pgdg90+1)

Use the command dir to list all the directories and files in a directory; ls is a unix command.

function function_one() {
  function_two();

function function_two() {

I read these algorithm from the book "multiple view geometry"

following text using

' as transpose sign

* as dot product

x as cross product, when using as operator

1. line definition

a point x_vec = (x, y)' lies on the line ax + by + c = 0

we denote L = (a, b, c)', the point as (x, y, 1)' as homogeneous coordinates

the line equation can be written as

(x, y, 1)(a, b, c)' = 0 or x' * L = 0

2. intersection of lines

we have two lines L1=(a1, b1, c1)', L2=(a2, b2, c2)'

assume x is a point, a vector, and x = L1 x L2 (L1 cross product L2).

be careful, x is always a 2D point, please read homogeneous coordinates if you are confused about (L1xL2) is a three elements vector, and x is a 2D coordinates.

according to triple product, we know that

L1 * ( L1 x L2 ) = 0, and L2 * (L1 x L2) = 0, because of L1,L2 co-plane

we substitute (L1xL2) with vector x, then we have L1*x=0, L2*x=0, which means x lie on both L1 and L2, x is the intersection point.

be careful, here x is homogeneous coordinates, if the last element of x is zero, it means L1 and L2 are parallel.

I solved with these:

.card-img-top {
    max-height: 20vh; /*not want to take all vertical space*/
    object-fit: contain;/*show all image, autosized, no cut, in available space*/
}

I know this has been answered many times, and all are correct, but I though I would add another:

Similar to the Ctrl - D method to select individual occurrences of the current selection, you can select all occurrences in the file with Alt+F3 when using Windows or Linux (CMD+CTRL+G in Mac world).

This is helpful for mass-changes.

You can set the color of a JLabel by altering the foreground category:

JLabel title = new JLabel("I love stackoverflow!", JLabel.CENTER);

title.setForeground(Color.white);

As far as I know, the simplest way to create the two-color label you want is to simply make two labels, and make sure they get placed next to each other in the proper order.

The [] operator is called an indexer. You can provide indexers that take an integer, a string, or any other type you want to use as a key. The syntax is straightforward, following the same principles as property accessors.

For example, in your case where an int is the key or index:

public int this[int index]
{
    get => GetValue(index);
}

You can also add a set accessor so that the indexer becomes read and write rather than just read-only.

public int this[int index]
{
    get => GetValue(index);
    set => SetValue(index, value);
}

If you want to index using a different type, you just change the signature of the indexer.

public int this[string index]
...

Since, I test more times this script more useful by 1 million records each page 100 records with pagination work faster my PC execute this script 0 sec while compare with mysql have own limit and offset about 4.5 sec to get the result.

Someone may miss understanding Row_Number() always sort by specific field. In case we need to define only row in sequence should use:

ROW_NUMBER() OVER (ORDER BY (SELECT NULL))

SELECT TOP {LIMIT} * FROM (
      SELECT TOP {LIMIT} + {OFFSET} ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS ROW_NO,*
      FROM  {TABLE_NAME}
) XX WHERE ROW_NO > {OFFSET}

Explain:

• {LIMIT}: Number of records for each page
• {OFFSET}: Number of skip records

I added Anaconda3/Library/Bin to the environment path and PyCharm no longer complained with the error.

IN GALAXY Devices :

You need to make sure that you havn't turned it off in the device using the Settings > Developer Options:

I'm not sure if this was your problem but for anyone that's trying to access his web application from his machine and having this problem:

Make sure you're connecting to 127.0.0.1 (a.k.a localhost) and not to your external IP address.

Your URL should be something like http://localhost:8181/ or http://127.0.0.1:8181 and not http://YourExternalIPaddress:8181/.

When you connect to your external IP address, you connect to you from the internet, as if you were a stranger (or a hacker).
However when you connect to your localhost, you connect locally as yourself and the block is obviously not needed (& avoided altogether).

I just use contentsMargin to fix the aspect ratio.

    updateMargins();
    QLabel::resizeEvent(event);
}

void AspectRatioLabel::updateMargins()
{
    if (pixmapWidth <= 0 || pixmapHeight <= 0)
        return;

    int w = this->width();
    int h = this->height();

    if (w <= 0 || h <= 0)
        return;

    if (w * pixmapHeight > h * pixmapWidth)
    {
        int m = (w - (pixmapWidth * h / pixmapHeight)) / 2;
        setContentsMargins(m, 0, m, 0);
    }
    else
    {
        int m = (h - (pixmapHeight * w / pixmapWidth)) / 2;
        setContentsMargins(0, m, 0, m);
    }
}

Works perfectly for me so far. You're welcome.

The best solution is: from positive to negative or from negative to positive

For negative:

SELECT ABS(a) * -1 AS AbsoluteA, ABS(b) * -1 AS AbsoluteB
FROM YourTable

For positive:

SELECT ABS(a) AS AbsoluteA, ABS(b)  AS AbsoluteB
FROM YourTable

It reads Hello World (cat), replaces all (g) occurrences of % by $ and (over)writes it to /etc/init.d/dropbox as root.

I tried this (and worked for me):

var img = 'data:image/png;base64, ...'; //place ur base64 encoded img here
document.body.style.backgroundImage = 'url(\'' + img + '\')';

ES6 syntax:

let img = 'data:image/png;base64, ...'
document.body.style.backgroundImage = `url('${img}')`

A bit better:

let setBackground = src => {
    this.style.backgroundImage = `url('${src}')`
};

let node = nodeIGotFromDOM, img = imageBase64EncodedFromMyGF;
setBackground.call(node, img);

From this article on web.archive.org :

The trick is to use the OnClientClick and UseSubmitBehavior properties of the button control. There are other methods, involving code on the server side to add attributes, but I think the simplicity of doing it this way is much more attractive:

<asp:Button runat="server" ID="BtnSubmit"  OnClientClick="this.disabled = true; this.value = 'Submitting...';"   UseSubmitBehavior="false"  OnClick="BtnSubmit_Click"  Text="Submit Me!" />

OnClientClick allows you to add client side OnClick script. In this case, the JavaScript will disable the button element and change its text value to a progress message. When the postback completes, the newly rendered page will revert the button back its initial state without any additional work.

The one pitfall that comes with disabling a submit button on the client side is that it will cancel the browser’s submit, and thus the postback. Setting the UseSubmitBehavior property to false tells .NET to inject the necessary client script to fire the postback anyway, instead of relying on the browser’s form submission behavior. In this case, the code it injects would be:

__doPostBack('BtnSubmit','')

This is added to the end of our OnClientClick code, giving us this rendered HTML:

<input type="button" name="BtnSubmit"  onclick="this.disabled = true; this.value ='Submitting...';__doPostBack('BtnSubmit','')"  value="Submit Me!" id="BtnSubmit" />

This gives a nice button disable effect and processing text, while the postback completes.

In Python 2:

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a, list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

In Python 3:

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> list(zip(list_a, list_b))
[(1, 5), (2, 6), (3, 7), (4, 8)]

There are a few ways to go about this. One option would be to use inputfile.read() instead of inputfile.readlines() - you'd need to write separate code to strip the first four lines, but if you want the final output as a single string anyway, this might make the most sense.

A second, simpler option would be to rejoin the strings after striping the first four lines with my_text = ''.join(my_text). This is a little inefficient, but if speed isn't a major concern, the code will be simplest.

Finally, if you actually want the output as a list of strings instead of a single string, you can just modify your data parser to iterate over the list. That might looks something like this:

def data_parser(lines, dic):
    for i, j in dic.iteritems():
        for (k, line) in enumerate(lines):
            lines[k] = line.replace(i, j)
    return lines

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

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

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

It looks like you forgot the prefix on the color attribute. Try

 <stroke android:width="2dp" android:color="#ff00ffff"/>

Updated Feb 2018: OpenBrace Limited has closed down, and its ObMimic product is no longer supported.

Here's another alternative, using OpenBrace's ObMimic library of Servlet API test-doubles (disclosure: I'm its developer).

        assertEquals("...expected result from dataManager.register...",
            response.getMimicState().getBodyContentAsString());

    }

}

Notes:

• Each "mimic" has a "mimicState" object for its logical state. This provides a clear distinction between the Servlet API methods and the configuration and inspection of the mimic's internal state.

• You might be surprised that the check of Content-Type includes "charset=ISO-8859-1". However, for the given "doPost" code this is as per the Servlet API Javadoc, and the HttpServletResponse's own getContentType method, and the actual Content-Type header produced on e.g. Glassfish 3. You might not realise this if using normal mock objects and your own expectations of the API's behaviour. In this case it probably doesn't matter, but in more complex cases this is the sort of unanticipated API behaviour that can make a bit of a mockery of mocks!

• I've used response.getMimicState().getContentType() as the simplest way to check Content-Type and illustrate the above point, but you could indeed check for "text/html" on its own if you wanted (using response.getMimicState().getContentTypeMimeType()). Checking the Content-Type header the same way as for the Cache-Control header also works.

• For this example the response content is checked as character data (with this using the Writer's encoding). We could also check that the response's Writer was used rather than its OutputStream (using response.getMimicState().isWritingCharacterContent()), but I've taken it that we're only concerned with the resulting output, and don't care what API calls produced it (though that could be checked too...). It's also possible to retrieve the response's body content as bytes, examine the detailed state of the Writer/OutputStream etc.

There are full details of ObMimic and a free download at the OpenBrace website. Or you can contact me if you have any questions (contact details are on the website).

I usually use

if(!(jQuery.inArray("test", myarray) < 0))

or

if(jQuery.inArray("test", myarray) >= 0)

There is a way to do this without installing putty on your Mac. You can easily convert your existing PPK file to a PEM file using PuTTYgen on Windows.

Launch PuTTYgen and then load the existing private key file using the Load button. From the "Conversions" menu select "Export OpenSSH key" and save the private key file with the .pem file extension.

Copy the PEM file to your Mac and set it to be read-only by your user:

chmod 400 <private-key-filename>.pem

Then you should be able to use ssh to connect to your remote server

ssh -i <private-key-filename>.pem username@hostname

// Here is very simple way to go:

// Your DataSet.

let numberArray = [
  {
    "x": "8/11/2009",
    "y": 0.026572007
  },
  {
    "x": "8/12/2009",
    "y": 0.025057454
  },
  {
    "x": "8/13/2009",
    "y": 0.024530916
  },
  {
    "x": "8/14/2009",
    "y": 0.031004457
  }
]

// 1. First create Array, containing all the value of Y
let result = numberArray.map((y) => y)
console.log(result) // >> [0.026572007,0.025057454,0.024530916,0.031004457]

// 2.
let maxValue = Math.max.apply(null, result)
console.log(maxValue) // >> 0.031004457

Although the given responses are correct, they modify the initial data frame, which is not always desirable (and, given the OP asked for examples "using apply", it might be they wanted a version that returns a new data frame, as apply does).

This is possible using assign: it is valid to assign to existing columns, as the documentation states (emphasis is mine):

Assign new columns to a DataFrame.

Returns a new object with all original columns in addition to new ones. Existing columns that are re-assigned will be overwritten.

In short:

In [1]: import pandas as pd

In [2]: df = pd.DataFrame([{'a': 15, 'b': 15, 'c': 5}, {'a': 20, 'b': 10, 'c': 7}, {'a': 25, 'b': 30, 'c': 9}])

In [3]: df.assign(a=lambda df: df.a / 2)
Out[3]: 
      a   b  c
0   7.5  15  5
1  10.0  10  7
2  12.5  30  9

In [4]: df
Out[4]: 
    a   b  c
0  15  15  5
1  20  10  7
2  25  30  9

Note that the function will be passed the whole dataframe, not only the column you want to modify, so you will need to make sure you select the right column in your lambda.

The answer of @NeplatnyUdaj is right but consider that Excel want the function name in the set language, in my case German. Then you need to use "DATUM" instead of "DATE":

=(((COLUMN_ID_HERE/60)/60)/24)+DATUM(1970,1,1)

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

public static int RemoveDuplicates(ref int[] array)
{
    int size = array.Length;

    // if 0 or 1, return 0 or 1:
    if (size  < 2) {
        return size;
    }

    int current = 0;
    for (int candidate = 1; candidate < size; ++candidate) {
        if (array[current] != array[candidate]) {
            array[++current] = array[candidate];
        }
    }

    // index to count conversion:
    return ++current;
}

<div style="cursor: pointer;" onclick="theFunction()">

is the simplest thing that works.

Of course in the final solution you should separate the markup from styling (css) and behavior (javascript) - read on it on a list apart for good practices on not just solving this particular problem but in markup design in general.

In case you don't have Linq, I solved it the following way:

    private T[] GetArray<T>(IList<T> iList) where T: new()
    {
        var result = new T[iList.Count];

        iList.CopyTo(result, 0);

        return result;
    }

Hope it helps

Here's an alternate solution, without using dblink.

Suppose B represents the source database and A represents the target database: Then,

1. Copy table from source DB to target DB:

   pg_dump -t <source_table> <source_db> | psql <target_db>
   

2. Open psql prompt, connect to target_db, and use a simple insert:

   psql
   # \c <target_db>;
   # INSERT INTO <target_table>(id, x, y) SELECT id, x, y FROM <source_table>;
   

3. At the end, delete the copy of source_table that you created in target_table.

   # DROP TABLE <source_table>;
   

Yo can set FlowDirection of Stack panel to RightToLeft, and then all items will be aligned to the right side.

I've found the taglist plug-in a must-have. It lists all tags that it knows about (files that you have opened) in a seperate window and makes it very easy to navigate larger files.

I use it mostly for Python development, but it can only be better for C/C++.

First check the variables declared using proper Datatypes. I had a same problem then I have checked, by mistake I declared SAPUser as int datatype so that the error occurred. One more thing XML file stores its data using concept like array but its first index starts having +1. e.g. if error is in(7,2) then check for 6th line always.....

For everyone who is encountering this and wants to accept the risk to test it, there is a solution: go to Incognito mode in Chrome and you'll be able to open "Advanced" and click "Proceed to some.url".

This can be helpful if you need to check some website which you are maintaining yourself and just testing as a developer (and when you don't yet have proper development certificate configured).

Of course this is NOT FOR PEOPLE using a website in production where this error indicates that there is a problem with website security.

This is what ended up working.

$("select").change(function(){
    $.get("/page.html?" + $(this).parent("form").find(":input").serialize()); 
});

background: rgba(0,0,0,.5);

you can use rgba for opacity, will only work in ie9+ and better browsers

If you have to click OK after entering your passcode, this command will unlock your phone:

adb shell input text XXXX && adb shell input keyevent 66

Where

• XXXX is your passcode.
• 66 is keycode of button OK.
• adb shell input text XXXX will enter your passcode.
• adb shell input keyevent 66 will simulate click the OK button

What

Basically the difference between kernel and user modes is not OS dependent and is achieved only by restricting some instructions to be run only in kernel mode by means of hardware design. All other purposes like memory protection can be done only by that restriction.

How

It means that the processor lives in either the kernel mode or in the user mode. Using some mechanisms the architecture can guarantee that whenever it is switched to the kernel mode the OS code is fetched to be run.

Why

Having this hardware infrastructure these could be achieved in common OSes:

• Protecting user programs from accessing whole the memory, to not let programs overwrite the OS for example,
• preventing user programs from performing sensitive instructions such as those that change CPU memory pointer bounds, to not let programs break their memory bounds for example.

this works for me:

It can be used inside the dialog, but the dialog can´t be inside any componet such as panels, accordion, etc.

Use this

select * from (
 SELECT ARIDNR,LIEFNR,row_number() over 
     (partition by ARIDNR order by ARIDNR) as RowNum) a
where a.RowNum >1

Presuming you have a .dmp file created by oracle exp then

imp help=y

will be your friend. It will lead you to

imp file=<file>.dmp show=y

to see the contents of the dump and then something like

imp scott/tiger@example file=<file>.dmp fromuser=<source> touser=<dest>

to import from one user to another. Be prepared for a long haul though if it is a complicated schema as you will need to precreate all referenced schema users, and tablespaces to make the imp work correctly

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

Below are code snippets to create and delete a cookie. The cookie is set for 1 day.

// 1 Day = 24 Hrs = 24*60*60 = 86400.

1. By using max-age:

   • Creating the cookie:

   document.cookie = "cookieName=cookieValue; max-age=86400; path=/;";
   

   • Deleting the cookie:

   document.cookie = "cookieName=; max-age=- (any digit); path=/;";
   

2. By using expires:

   • Syntax for creating the cookie for one day:

   var expires = (new Date(Date.now()+ 86400*1000)).toUTCString();
   document.cookie = "cookieName=cookieValue; expires=" + expires + 86400) + ";path=/;"
   

The best solution is to get a copy of Node's type definitions. This will solve all kinds of dependency issues, not only require(). This was previously done using packages like typings, but as Mike Chamberlain mentioned, Typings are deprecated. The modern way is doing it like this:

npm install --save-dev @types/node

Not only will it fix the compiler error, it will also add the definitions of the Node API to your IDE.

If you want to use the SQL ISO standard INFORMATION_SCHEMA and not the SQL Server-specific sysobjects, you can do this:

IF EXISTS (
    SELECT ROUTINE_NAME FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_NAME = N'FunctionName'
)
   DROP FUNCTION [dbo].[FunctionName]
GO

Try this:

print("".join(str(x) for x in This))

Above shown methods did not work for me, may be i am using bit old jquery, then finally the below shown code snippet works for - posting just in case somebody in my same position

$('#textBox').live('keydown', function(e) {
    if (e.keyCode == 9) {
        e.preventDefault();
        alert('tab');
    }
});

Yes it's an issue in webkit and also reported in chromium: http://code.google.com/p/chromium/issues/detail?id=773 It's there since 2008... and still not fixed!!

I'm using a piece of javacsript and jQuery to make my way around this.

function showAlt(){$(this).replaceWith(this.alt)};
function addShowAlt(selector){$(selector).error(showAlt).attr("src", $(selector).src)};
addShowAlt("img");

If you only want one some images:

addShowAlt("#myImgID");

The detach/copy/attach method will take down the database. That's not something you'd want in production.

The backup/restore will only work if you have write permissions to the production server. I work with Amazon RDS and I don't.

The import/export method doesn't really work because of foreign keys - unless you do tables one by one in the order they reference one another. You can do an import/export to a new database. That will copy all the tables and data, but not the foreign keys.

This sounds like a common operation one needs to do with database. Why isn't SQL Server handling this properly? Every time I had to do this it was frustrating.

That being said, the only painless solution I've encountered was Sql Azure Migration Tool which is maintained by the community. It works with SQL Server too.

I have a cook recipe for finding things in linux/macos

First update the locate db then do a

locate WHATiWANTtoSEARCH | less

do a /find to find what you are looking for.

to update your locate db in macos do this:

sudo /usr/libexec/locate.updatedb

it sometimes takes a while. Hope this helps :)

I think stash -p is probably the choice you want, but just in case you run into other even more tricky things in the future, remember that:

Stash is really just a very simple alternative to the only slightly more complex branch sets. Stash is very useful for moving things around quickly, but you can accomplish more complex things with branches without that much more headache and work.

# git checkout -b tmpbranch
# git add the_file
# git commit -m "stashing the_file"
# git checkout master

go about and do what you want, and then later simply rebase and/or merge the tmpbranch. It really isn't that much extra work when you need to do more careful tracking than stash will allow.

You have to pass the route parameters to the route method, for example:

<li><a href="{{ route('user.profile', $nickname) }}">Profile</a></li>
<li><a href="{{ route('user.settings', $nickname) }}">Settings</a></li>

It's because, both routes have a {nickname} in the route declaration. I've used $nickname for example but make sure you change the $nickname to appropriate value/variable, for example, it could be something like the following:

<li><a href="{{ route('user.settings', auth()->user()->nickname) }}">Settings</a></li>

I recently ran into the same problem having the TCPDF work with my CSS. Take a look at the code below. It worked for me after I changed the standard CSS to a format PHP would understand

Code Sample Below

$table = '<table width="100%" cellspacing="0" cellpadding="55%">
          <tr valign="bottom">
                <td class="header1" rowspan="2" align="center" valign="middle"
                      width="6%">Category</td>
                <td class="header1" rowspan="2" align="center" valign="middle"
                      width="26%">Project Description</td>
          </tr></table>';

If you use jquery.ui, try this code:

$.position.scrollbarWidth()

Element needs to be a variant, so you can't declare it as a string. Your function should accept a variant if it is a string though as long as you pass it ByVal.

Public Sub example()
    Dim sArray(4) As string
    Dim element As variant

    For Each element In sArray
        do_something (element)
    Next element
End Sub


Sub do_something(ByVal e As String)

End Sub

The other option is to convert the variant to a string before passing it.

  do_something CStr(element)

You can try:

$("._someDropDown").val();

sys.stdout.write("%-6s %-50s %-25s\n" % (code, name, industry))

on a side note you can make the width variable with *-s

>>> d = "%-*s%-*s"%(25,"apple",30,"something")
>>> d
'apple                    something                     '

You can use the CultureInfo to get the month name. You can even get the short month name as well as other fun things.

I would suggestion you put these into extension methods, which will allow you to write less code later. However you can implement however you like.

Here is an example of how to do it using extension methods:

using System;
using System.Globalization;

class Program
{
    static void Main()
    {

        Console.WriteLine(DateTime.Now.ToMonthName());
        Console.WriteLine(DateTime.Now.ToShortMonthName());
        Console.Read();
    }
}

static class DateTimeExtensions
{
    public static string ToMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(dateTime.Month);
    }

    public static string ToShortMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(dateTime.Month);
    }
}

Hope this helps!

You have no shell at /bin/sh? Have you tried docker run -it pensu/busybox /usr/bin/sh ?

ReSTful APIs are consumed primarily by other systems, which is why I put paging data in the response headers. However, some API consumers may not have direct access to the response headers, or may be building a UX over your API, so providing a way to retrieve (on demand) the metadata in the JSON response is a plus.

I believe your implementation should include machine-readable metadata as a default, and human-readable metadata when requested. The human-readable metadata could be returned with every request if you like or, preferably, on-demand via a query parameter, such as include=metadata or include_metadata=true.

In your particular scenario, I would include the URI for each product with the record. This makes it easy for the API consumer to create links to the individual products. I would also set some reasonable expectations as per the limits of my paging requests. Implementing and documenting default settings for page size is an acceptable practice. For example, GitHub's API sets the default page size to 30 records with a maximum of 100, plus sets a rate limit on the number of times you can query the API. If your API has a default page size, then the query string can just specify the page index.

In the human-readable scenario, when navigating to /products?page=5&per_page=20&include=metadata, the response could be:

{
  "_metadata": 
  {
      "page": 5,
      "per_page": 20,
      "page_count": 20,
      "total_count": 521,
      "Links": [
        {"self": "/products?page=5&per_page=20"},
        {"first": "/products?page=0&per_page=20"},
        {"previous": "/products?page=4&per_page=20"},
        {"next": "/products?page=6&per_page=20"},
        {"last": "/products?page=26&per_page=20"},
      ]
  },
  "records": [
    {
      "id": 1,
      "name": "Widget #1",
      "uri": "/products/1"
    },
    {
      "id": 2,
      "name": "Widget #2",
      "uri": "/products/2"
    },
    {
      "id": 3,
      "name": "Widget #3",
      "uri": "/products/3"
    }
  ]
}

For machine-readable metadata, I would add Link headers to the response:

Link: </products?page=5&perPage=20>;rel=self,</products?page=0&perPage=20>;rel=first,</products?page=4&perPage=20>;rel=previous,</products?page=6&perPage=20>;rel=next,</products?page=26&perPage=20>;rel=last

(the Link header value should be urlencoded)

...and possibly a custom total-count response header, if you so choose:

total-count: 521

The other paging data revealed in the human-centric metadata might be superfluous for machine-centric metadata, as the link headers let me know which page I am on and the number per page, and I can quickly retrieve the number of records in the array. Therefore, I would probably only create a header for the total count. You can always change your mind later and add more metadata.

As an aside, you may notice I removed /index from your URI. A generally accepted convention is to have your ReST endpoint expose collections. Having /index at the end muddies that up slightly.

These are just a few things I like to have when consuming/creating an API. Hope that helps!

Same with the following code:

static int f() {
    while (true) {
        try {
            return 1;
        } finally {
            break;
        }
    }
    return 2;
}

f will return 2!

To solve the 4G issue mentioned in the comments I have used @AshleyMills reachability implementation as a reference and rewritten Reachability for Swift 3.1:

updated: Xcode 10.1 • Swift 4 or later

Reachability.swift file

Usage

Initialize it in your AppDelegate.swift didFinishLaunchingWithOptions method and handle any errors that might occur:

import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        do {
            try Network.reachability = Reachability(hostname: "www.google.com")
        }
        catch {
            switch error as? Network.Error {
            case let .failedToCreateWith(hostname)?:
                print("Network error:\nFailed to create reachability object With host named:", hostname)
            case let .failedToInitializeWith(address)?:
                print("Network error:\nFailed to initialize reachability object With address:", address)
            case .failedToSetCallout?:
                print("Network error:\nFailed to set callout")
            case .failedToSetDispatchQueue?:
                print("Network error:\nFailed to set DispatchQueue")
            case .none:
                print(error)
            }
        }
        return true
    }
}

And a view controller sample:

import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        NotificationCenter.default
            .addObserver(self,
                         selector: #selector(statusManager),
                         name: .flagsChanged,
                         object: nil)
        updateUserInterface()
    }
    func updateUserInterface() {
        switch Network.reachability.status {
        case .unreachable:
            view.backgroundColor = .red
        case .wwan:
            view.backgroundColor = .yellow
        case .wifi:
            view.backgroundColor = .green
        }
        print("Reachability Summary")
        print("Status:", Network.reachability.status)
        print("HostName:", Network.reachability.hostname ?? "nil")
        print("Reachable:", Network.reachability.isReachable)
        print("Wifi:", Network.reachability.isReachableViaWiFi)
    }
    @objc func statusManager(_ notification: Notification) {
        updateUserInterface()
    }
}

Sample Project

StringUtils is in org.apache.commons.lang.* not in java.lang.*. Most importantly learn to read javadoc file. All java programmers after learning basic java learn to read javadoc, execute tests from public projects, use those jars in their projects.

If you are working on eclipse or netbeans you can make a directory (folder) called lib in your project (from within the IDE) and copy the downloaded jar from hard disk and paste it in that directory from eclipse or netbeans. Next you have to add it to your project.

E.g in case of eclipse from Project->Properties select Java Build Path -> Add Jars, point to the jar you copied earlier. In your case it might be commons-lang-version.jar.

After this step whenever you add above import in a java file, those libraries will be available on your project (in case of eclipse or netbeans).

From where do you get the jar for commons-lang? Root directory of any apache commons is http://commons.apache.org/ And for commons-lang it is http://commons.apache.org/lang/

Some of these libraries contain User Guide and other help to get you started, but javadoc is the ultimate guide for any java programmer.

It is right time you asked about this library, because you should never re-invent the wheel. Use apache commons and other well tested libraries whenever possible. By using those libraries you omit some common human errors and even test those libraries (using is testing). Sometimes in future when using this library, you may even write some modifications or addition to this library. If you contribute back, the world benefits.

Most common use of StringUtils is in web projects (when you want to check for blank or null strings, checking if a string is number, splitting strings with some token). StringUtils helps to get rid of those nasty NumberFormat and Null exceptions. But StringUtils can be used anywhere String is used.

We can simply use Collections.max() and Collections.min() method.

public class MaxList {
    public static void main(String[] args) {
        List l = new ArrayList();
        l.add(1);
        l.add(2);
        l.add(3);
        l.add(4);
        l.add(5);
        System.out.println(Collections.max(l)); // 5
        System.out.println(Collections.min(l)); // 1
    }
}

Add a reference to 'Microsoft.VisualStudio.QualityTools.UnitTestFramework" NuGet packet and it should successfully build it.

Provided you aren't using the same destination view controller with different identifiers, the code can be more concise than the other solutions (and avoids the as! in some of the other answers):

override func prepare(for segue: NSStoryboardSegue, sender: Any?) {
    if let myViewController = segue.destinationController as? MyViewController { 
        // Set up the VC
    }
}

To properly answer this qustion you need to consider PHP internals or the target that PHP is built for.

To answer this from a typical Linux perspective on x86...

Sizes of types in C: https://usrmisc.wordpress.com/2012/12/27/integer-sizes-in-c-on-32-bit-and-64-bit-linux/

Types used in PHP for variables: http://php.net/manual/en/internals2.variables.intro.php

Strings are always 2GB as the length is always 32bits and a bit is wasted because it uses int rather than uint. int is impractical for lengths over 2GB as it requires a cast to avoid breaking arithmetic or "than" comparisons. The extra bit is likely being used for overflow checks.

Strangely, hash keys might internally support 4GB as uint is used although I have never put this to the test. PHP hash keys have a +1 to the length for a trailing null byte which to my knowledge gets ignored so it may need to be unsigned for that edge case rather than to allow longer keys.

A 32bit system may impose more external limits.

Also, if you're just looking for a specific value nested within the JSON content you can do something like so:

yourJObject.GetValue("jsonObjectName").Value<string>("jsonPropertyName");

And so on from there.

This could help if you don't want to bear the cost of converting the entire JSON into a C# object.

You are getting a table scan there, meaning that you do not have an index defined on er101_upd_date_iso, or if that column is part of an existing index, the index can't be used (possibly it is not the primary indexer column).

Adding missing indexes will help performance no end.

there are already indexs on the columns which are queried most commonly

That does not mean they are used in this query (and they probably are not).

I suggest reading Finding the Causes of Poor Performance in SQL Server by Gail Shaw, part 1 and part 2.

SSH and Run Multiple Commands in Bash.

Separate commands with semicolons within a string, passed to echo, all piped into the ssh command. For example:

echo "df -k;uname -a" | ssh 192.168.79.134

I know this might be redundant but I use this script to batch convert files.

old_extension=$1
new_extension=$2

for i in *."$old_extension";
  do ffmpeg -i "$i" "${i%.*}.$new_extension";
done

It takes 2 arguments to make it more flexible :

1. the extension you want to convert from
2. the new extension you want to convert to

I create an alias for it but you can also use it manually like this:

sh batch_convert.sh mkv mp4

This would convert all the mkv files into mp4 files.

As you can see it slightly more versatile. As long as ffmpeg can convert it you can specify any two extensions.

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

Just want to point out you do not need to specify all dimensions of the array.

The leftmost dimension can be 'guessed' by the compiler.

#include <stdio.h>
int main(void) {
  int arr[][5] = {{1,2,3,4,5}, {5,6,7,8,9}, {6,5,4,3,2}};
  printf("sizeof arr is %d bytes\n", (int)sizeof arr);
  printf("number of elements: %d\n", (int)(sizeof arr/sizeof arr[0]));
  return 0;
}

10 * * * Sun

Position 1 for minutes, allowed values are 1-60
position 2 for hours, allowed values are 1-24
position 3 for day of month ,allowed values are 1-31
position 4 for month ,allowed values are 1-12 
position 5 for day of week ,allowed values are 1-7 or and the day starts at Monday. 

I think it is worthwhile to recap/summarize the choices here for clarity... then offer a new variation that I believe provides the best utility.

<1> ReadKey (System.Console)

write-host "Press any key to continue..."
[void][System.Console]::ReadKey($true)

• Advantage: Accepts any key but properly excludes Shift, Alt, Ctrl modifier keys.
• Disadvantage: Does not work in PS-ISE.

<2> ReadKey (RawUI)

Write-Host "Press any key to continue ..."
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

• Disadvantage: Does not work in PS-ISE.
• Disadvantage: Does not exclude modifier keys.

<3> cmd

cmd /c Pause | Out-Null

• Disadvantage: Does not work in PS-ISE.
• Disadvantage: Visibly launches new shell/window on first use; not noticeable on subsequent use but still has the overhead

<4> Read-Host

Read-Host -Prompt "Press Enter to continue"

• Advantage: Works in PS-ISE.
• Disadvantage: Accepts only Enter key.

<5> ReadKey composite

This is a composite of <1> above with the ISE workaround/kludge extracted from the proposal on Adam's Tech Blog (courtesy of Nick from earlier comments on this page). I made two slight improvements to the latter: added Test-Path to avoid an error if you use Set-StrictMode (you do, don't you?!) and the final Write-Host to add a newline after your keystroke to put the prompt in the right place.

Function Pause ($Message = "Press any key to continue . . . ") {
    if ((Test-Path variable:psISE) -and $psISE) {
        $Shell = New-Object -ComObject "WScript.Shell"
        $Button = $Shell.Popup("Click OK to continue.", 0, "Script Paused", 0)
    }
    else {     
        Write-Host -NoNewline $Message
        [void][System.Console]::ReadKey($true)
        Write-Host
    }
}

• Advantage: Accepts any key but properly excludes Shift, Alt, Ctrl modifier keys.
• Advantage: Works in PS-ISE (though only with Enter or mouse click)
• Disadvantage: Not a one-liner!

Why and when you should mark the request parameter as implicit:

Some methods that you will make use of in the body of your action have an implicit parameter list like, for example, Form.scala defines a method:

def bindFromRequest()(implicit request: play.api.mvc.Request[_]): Form[T] = { ... }

You don't necessarily notice this as you would just call myForm.bindFromRequest() You don't have to provide the implicit arguments explicitly. No, you leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit.

You explicitly mark it as available for implicit use.

You hint the compiler that it's "OK" to use the request object sent in by the Play framework (that we gave the name "request" but could have used just "r" or "req") wherever required, "on the sly".

myForm.bindFromRequest()

see it? it's not there, but it is there!

It just happens without your having to slot it in manually in every place it's needed (but you can pass it explicitly, if you so wish, no matter if it's marked implicit or not):

myForm.bindFromRequest()(request)

Without marking it as implicit, you would have to do the above. Marking it as implicit you don't have to.

When should you mark the request as implicit? You only really need to if you are making use of methods that declare an implicit parameter list expecting an instance of the Request. But to keep it simple, you could just get into the habit of marking the request implicit always. That way you can just write beautiful terse code.

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.

First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).

But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:

dotnet restore Project-File-Name.csproj

And that installs the package

Reasons why id based selectors don't work

1. The element/DOM with id specified doesn't exist yet.
2. The element exists, but it is not registered in DOM [in case of HTML nodes appended dynamically from Ajax responses].
3. More than one element with the same id is present which is causing a conflict.

Solutions

1. Try to access the element after its declaration or alternatively use stuff like $(document).ready();

2. For elements coming from Ajax responses, use the .bind() method of jQuery. Older versions of jQuery had .live() for the same.

3. Use tools [for example, webdeveloper plugin for browsers] to find duplicate ids and remove them.

text-align aligns text and other inline content. It doesn't align block element children.

To do that, you want to give the element you want aligned a width, with ‘auto’ left and right margins. This is the standards-compliant way that works everywhere except IE5.x.

<div style="width: 50%; margin: 0 auto;">Hello</div>

For this to work in IE6, you need to make sure Standards Mode is on by using a suitable DOCTYPE.

If you really need to support IE5/Quirks Mode, which these days you shouldn't really, it is possible to combine the two different approaches to centering:

<div style="text-align: center">
    <div style="width: 50%; margin: 0 auto; text-align: left">Hello</div>
</div>

(Obviously, styles are best put inside a stylesheet, but the inline version is illustrative.)

This is basically Marco Antônio's answer for a React custom hook, but modified to set the dimensions initially and not only after a resize.

export const useContainerDimensions = myRef => {
  const getDimensions = () => ({
    width: myRef.current.offsetWidth,
    height: myRef.current.offsetHeight
  })

  const [dimensions, setDimensions] = useState({ width: 0, height: 0 })

  useEffect(() => {
    const handleResize = () => {
      setDimensions(getDimensions())
    }

    if (myRef.current) {
      setDimensions(getDimensions())
    }

    window.addEventListener("resize", handleResize)

    return () => {
      window.removeEventListener("resize", handleResize)
    }
  }, [myRef])

  return dimensions;
};

Used in the same way:

const MyComponent = () => {
  const componentRef = useRef()
  const { width, height } = useContainerDimensions(componentRef)

  return (
    <div ref={componentRef}>
      <p>width: {width}px</p>
      <p>height: {height}px</p>
    <div/>
  )
}

Use .astype.

>>> a = numpy.array([1, 2, 3, 4], dtype=numpy.float64)
>>> a
array([ 1.,  2.,  3.,  4.])
>>> a.astype(numpy.int64)
array([1, 2, 3, 4])

See the documentation for more options.

That's because abc is undefined at the moment of the template rendering. You can use safe navigation operator (?) to "protect" template until HTTP call is completed:

{{abc?.xyz?.name}}

You can read more about safe navigation operator here.

Update:

Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf directive to overcome this problem:

<div *ngIf="arr && arr.length > 0">
    {{arr[0].name}}
</div>

Read more about NgIf directive here.

It comes with lots of easy array functions to never write a loop again

So you can just do:

NSArray* youngHeroes = [self.heroes filter:^BOOL(Hero *object) {
    return object.age.intValue < 20;
}];

or

NSArray* oldHeroes = [self.heroes reject:^BOOL(Hero *object) {
    return object.age.intValue < 20;
}];
