implementation 'com.github.bumptech.glide:glide:4.10.0'

Kotlin:

Glide.with(this)
        .asBitmap()
        .load(imagePath)
        .into(object : CustomTarget<Bitmap>(){
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                imageView.setImageBitmap(resource)
            }
            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })

Bitmap Size:

if you want to use the original size of the image use the default constructor as above, else You can pass your desired size for bitmap

into(object : CustomTarget<Bitmap>(1980, 1080)

Java:

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new CustomTarget<Bitmap>() {
            @Override
            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }

            @Override
            public void onLoadCleared(@Nullable Drawable placeholder) {
            }
        });

Old Answer:

With compile 'com.github.bumptech.glide:glide:4.8.0' and below

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }
        });

For compile 'com.github.bumptech.glide:glide:3.7.0' and below

Glide.with(this)
        .load(path)
        .asBitmap()
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                imageView.setImageBitmap(resource);
            }
        });

Now you might see a warning SimpleTarget is deprecated

Reason:

The main point of deprecating SimpleTarget is to warn you about the ways in which it tempts you to break Glide's API contract. Specifically, it doesn't do anything to force you to stop using any resource you've loaded once the SimpleTarget is cleared, which can lead to crashes and graphical corruption.

The SimpleTarget still can be used as long you make sure you are not using the bitmap once the imageView is cleared.

SELECT  name
FROM    orders,company
WHERE   orderID = 1
        AND companyID IN (attachedCompanyIDs)

attachedCompanyIDs is a scalar value which is cast into INT (type of companyID).

The cast only returns numbers up to the first non-digit (a comma in your case).

Thus,

companyID IN ('1,2,3') = companyID IN (CAST('1,2,3' AS INT)) = companyID IN (1)

In PostgreSQL, you could cast the string into array (or store it as an array in the first place):

SELECT  name
FROM    orders
JOIN    company
ON      companyID = ANY (('{' | attachedCompanyIDs | '}')::INT[])
WHERE   orderID = 1

and this would even use an index on companyID.

Unfortunately, this does not work in MySQL since the latter does not support arrays.

You may find this article interesting (see #2):

• 10 things in MySQL (that won’t work as expected)

Update:

If there is some reasonable limit on the number of values in the comma separated lists (say, no more than 5), so you can try to use this query:

SELECT  name
FROM    orders
CROSS JOIN
        (
        SELECT  1 AS pos
        UNION ALL
        SELECT  2 AS pos
        UNION ALL
        SELECT  3 AS pos
        UNION ALL
        SELECT  4 AS pos
        UNION ALL
        SELECT  5 AS pos
        ) q
JOIN    company
ON      companyID = CAST(NULLIF(SUBSTRING_INDEX(attachedCompanyIDs, ',', -pos), SUBSTRING_INDEX(attachedCompanyIDs, ',', 1 - pos)) AS UNSIGNED)

The best way for me was to put it in a hidden div in php blade

<div hidden id="token">{{$token}}</div>

then call it in javascript as a constant to avoid undefined var errors

const token = document.querySelector('div[id=token]').textContent

// console.log(token)
// eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOiI5MjNlOTcyMi02N2NmLTQ4M2UtYTk4Mi01YmE5YTI0Y2M2MzMiLCJqdGkiOiI2Y2I1ZGRhNzRhZjNhYTkwNzA3ZjMzMDFiYjBiZDUzNTZjNjYxMGUyZWJlNmYzOTI5NzBmMjNjNDdiNjhjY2FiYjI0ZWVmMzYwZmNiZDBmNyIsImlhdCI6IjE2MDgwODMyNTYuNTE2NjE4IiwibmJmIjoiMTYwODA4MzI1Ni41MTY2MjUiLCJleHAiOiIxNjIzODA4MDU2LjMxMTg5NSIsInN1YiI6IjUiLCJzY29wZXMiOlsiYWRtaW4iXX0.GbKZ8CIjt3otzFyE5aZEkNBCtn75ApIfS6QbnD6z0nxDjycknQaQYz2EGems9Z3Qjabe5PA9zL1mVnycCieeQfpLvWL9xDu9hKkIMs006Sznrp8gWy6JK8qX4Xx3GkzWEx8Z7ZZmhsKUgEyRkqnKJ-1BqC2tTiTBqBAO6pK_Pz7H74gV95dsMiys9afPKP5ztW93kwaC-pj4h-vv-GftXXc6XDnUhTppT4qxn1r2Hf7k-NXE_IHq4ZPb20LRXboH0RnbJgq2JA1E3WFX5_a6FeWJvLlLnGGNOT0ocdNZq7nTGWwfocHlv6pH0NFaKa3hLoRh79d5KO_nysPVCDt7jYOMnpiq8ybIbe3oYjlWyk_rdQ9067bnsfxyexQwLC3IJpAH27Az8FQuOQMZg2HJhK8WtWUph5bsYUU0O2uPG8HY9922yTGYwzeMEdAqBss85jdpMNuECtlIFM1Pc4S-0nrCtBE_tNXn8ATDrm6FecdSK8KnnrCOSsZhR04MvTyznqCMAnKtN_vMDpmIAmPd181UanjO_kxR7QIlsEmT_UhM1MBmyfdIEvHkgLgUdUouonjQNvOKwCrrgDkP0hkZQff-iuHPwpL-CUjw7GPa70lp-TIDhfei8T90RkAXte1XKv7ku3sgENHTwPrL9QSrNtdc5MfB9AbUV-tFMJn9T7k

Now that I've separated the classes to .h and .cpp files do I need to use a makefile or can I still use the "g++ main.cpp" command?

Compiling several files at once is a poor choice if you are going to put that into the Makefile.

Normally in a Makefile (for GNU/Make), it should suffice to write that:

# "all" is the name of the default target, running "make" without params would use it
all: executable1

# for C++, replace CC (c compiler) with CXX (c++ compiler) which is used as default linker
CC=$(CXX)

# tell which files should be used, .cpp -> .o make would do automatically
executable1: file1.o file2.o

That way make would be properly recompiling only what needs to be recompiled. One can also add few tweaks to generate the header file dependencies - so that make would also properly rebuild what's need to be rebuilt due to the header file changes.

How about subtracting one and changing Sunday

IF(DAYOFWEEK() = 1, 7, DAYOFWEEK() - 1)

Of course you would have to do this for every query.

You can save the whole jstl object as a Javascript object by converting the whole object to json. It is possible by Jackson in java.

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonUtil{
   public static String toJsonString(Object obj){
      ObjectMapper objectMapper = ...; // jackson object mapper
      return objectMapper.writeValueAsString(obj);
   }
}

I get this error when my project .net framework version does not match the framework version of the DLL I am linking to. In my case, I was getting:

"The type or namespace name 'UserVoice' could not be found (are you missing a using directive or an assembly reference?).

UserVoice was .Net 4.0, and my project properties were set to ".Net 4.0 Client Profile". Changing to .Net 4.0 on the project cleared the error. I hope this helps someone.

String str_date=month+"-"+day+"-"+yr;
DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy");
Date date = (Date)formatter.parse(str_date); 
long output=date.getTime()/1000L;
String str=Long.toString(output);
long timestamp = Long.parseLong(str) * 1000;

A simple solution is send a timestamp to MySQL and let it do the conversion. Javascript uses timestamps in milliseconds whereas MySQL expects them to be in seconds - so a division by 1000 is needed:

// Current date / time as a timestamp:
let jsTimestamp = Date.now();

// **OR** a specific date / time as a timestamp:
jsTimestamp = new Date("2020-11-17 16:34:59").getTime();

// Adding 30 minutes (to answer the second part of the question):
jsTimestamp += 30 * 1000;

// Example query converting Javascript timestamp into a MySQL date
let sql = 'SELECT FROM_UNIXTIME(' + jsTimestamp + ' / 1000) AS mysql_date_time';

If you don't have to use the support library then have a look at Roman's answer.

But if you want to use the support library you have to use the old animation framework as described below.

After consulting Reto's and blindstuff's answers I have gotten the following code working.

The fragments appear sliding in from the right and sliding out to the left when back is pressed.

FragmentManager fragmentManager = getSupportFragmentManager();

FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter, R.anim.exit, R.anim.pop_enter, R.anim.pop_exit);

CustomFragment newCustomFragment = CustomFragment.newInstance();
transaction.replace(R.id.fragment_container, newCustomFragment );
transaction.addToBackStack(null);
transaction.commit();

The order is important. This means you must call setCustomAnimations() before replace() or the animation will not take effect!

Next these files have to be placed inside the res/anim folder.

enter.xml:

<?xml version="1.0" encoding="utf-8"?>
<set>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
               android:fromXDelta="100%"
               android:toXDelta="0"
               android:interpolator="@android:anim/decelerate_interpolator"
               android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit.xml:

<set>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
               android:fromXDelta="0"
               android:toXDelta="-100%"
               android:interpolator="@android:anim/accelerate_interpolator"
               android:duration="@android:integer/config_mediumAnimTime"/>
</set>

pop_enter.xml:

<set>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
               android:fromXDelta="-100%"
               android:toXDelta="0"
               android:interpolator="@android:anim/decelerate_interpolator"
               android:duration="@android:integer/config_mediumAnimTime"/>
</set>

pop_exit.xml:

<?xml version="1.0" encoding="utf-8"?>
<set>
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
               android:fromXDelta="0"
               android:toXDelta="100%"
               android:interpolator="@android:anim/accelerate_interpolator"
               android:duration="@android:integer/config_mediumAnimTime"/>
</set>

The duration of the animations can be changed to any of the default values like @android:integer/config_shortAnimTime or any other number.

Note that if in between fragment replacements a configuration change happens (for example rotation) the back action isn't animated. This is a documented bug that still exists in the rev 20 of the support library.

If you have a compiler that supports the alloca() function, then this is possible solution (quite ugly though):

printf("%s", (char*)memset(memset(alloca(10), '\0', 10), 'x', 9));

It basically allocates 10 bytes on the stack which are filled with '\0' and then the first 9 bytes are filled with 'x'.

If you have a C99 compiler, then this might be a neater solution:

for (int i = 0;  i < 10;  i++, printf("%c", 'x'));

git.exe is common for any git based applications like GitHub, Bitbucket etc. Some times it is possible that you have already installed another git based application so git.exe will be present in the bin folder of that application.

For example if you installed bitbucket before github in your PC, you will find git.exe in C:\Users\{username}\AppData\Local\Atlassian\SourceTree\git_local\bin instead of C:\Users\{username}\AppData\Local\GitHub\PortableGit.....\bin.

I used to always get confused whether I should use break, or continue. This is what helps me remember:

When to use break vs continue?

1. Break - it's like breaking up. It's sad, you guys are parting. The loop is exited.

2. Continue - means that you're gonna give today a rest and sort it all out tomorrow (i.e. skip the current iteration)!

Nobody mentioned:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
    }

If you get your string from stdin().read_line, you have to trim it first.

let my_num: i32 = my_num.trim().parse()
   .expect("please give me correct string number!");

Getting the correct URL for your camera seems to be the actual challenge! I'm putting my working URL here, it might help someone. The camera is EZVIZ C1C with exact model cs-c1c-d0-1d2wf. The working URL is

rtsp://admin:[email protected]/h264_stream

where SZGBZT is the verification code found at the bottom of the camera. admin is always admin regardless of any settings or users you have.

The final code will be

video_capture = cv2.VideoCapture('rtsp://admin:[email protected]/h264_stream')

With Swift 3 and Swift 4, String has a method called data(using:allowLossyConversion:). data(using:allowLossyConversion:) has the following declaration:

func data(using encoding: String.Encoding, allowLossyConversion: Bool = default) -> Data?

Returns a Data containing a representation of the String encoded using a given encoding.

With Swift 4, String's data(using:allowLossyConversion:) can be used in conjunction with JSONDecoder's decode(_:from:) in order to deserialize a JSON string into a dictionary.

Furthermore, with Swift 3 and Swift 4, String's data(using:allowLossyConversion:) can also be used in conjunction with JSONSerialization's json?Object(with:?options:?) in order to deserialize a JSON string into a dictionary.

#1. Swift 4 solution

With Swift 4, JSONDecoder has a method called decode(_:from:). decode(_:from:) has the following declaration:

func decode<T>(_ type: T.Type, from data: Data) throws -> T where T : Decodable

Decodes a top-level value of the given type from the given JSON representation.

The Playground code below shows how to use data(using:allowLossyConversion:) and decode(_:from:) in order to get a Dictionary from a JSON formatted String:

let jsonString = """
{"password" : "1234",  "user" : "andreas"}
"""

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let decoder = JSONDecoder()
        let jsonDictionary = try decoder.decode(Dictionary<String, String>.self, from: data)
        print(jsonDictionary) // prints: ["user": "andreas", "password": "1234"]
    } catch {
        // Handle error
        print(error)
    }
}

#2. Swift 3 and Swift 4 solution

With Swift 3 and Swift 4, JSONSerialization has a method called json?Object(with:?options:?). json?Object(with:?options:?) has the following declaration:

class func jsonObject(with data: Data, options opt: JSONSerialization.ReadingOptions = []) throws -> Any

Returns a Foundation object from given JSON data.

The Playground code below shows how to use data(using:allowLossyConversion:) and json?Object(with:?options:?) in order to get a Dictionary from a JSON formatted String:

import Foundation

let jsonString = "{\"password\" : \"1234\",  \"user\" : \"andreas\"}"

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let jsonDictionary = try JSONSerialization.jsonObject(with: data, options: []) as? [String : String]
        print(String(describing: jsonDictionary)) // prints: Optional(["user": "andreas", "password": "1234"])
    } catch {
        // Handle error
        print(error)
    }
}

I am gonna write what iv done very briefly (to delete any CocoaPods from my project)..

1. delete any added folder (frameworks, Pods,...)
2. delete any added files (PROJECT.xcworkspace, PodFile, PodFile.lock, Pods-PROJECT.debug.xcconfig, Pods-PROJECT.release.xcconfig,...)
3. just leave your original ones (PROJECT, PROJECT_Tests, PROJECT.xcodeproj)
4. remove framework reference from the project on xcode

To remove the framework reference from xcode:

1. Use the Project Navigator
2. Select Project
3. Select Target PROJECT
4. Select Build Phases from the top options
5. leave the default groups (Target Dependencies, Compile Sources, Linked Binary with Libraries, Copy Bundle Resources) and delete any other

Also, using the StringBuilder.AppendLine method.

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

Here is a JSFiddle that demonstrates this technique.

First solution: if you are using C++11

Since this was asked there were a bit of new developments: it is important to know that std::isnan() is part of C++11

Synopsis

Defined in header <cmath>

bool isnan( float arg ); (since C++11)
bool isnan( double arg ); (since C++11)
bool isnan( long double arg ); (since C++11)

Determines if the given floating point number arg is not-a-number (NaN).

Parameters

arg: floating point value

Return value

true if arg is NaN, false otherwise

Reference

http://en.cppreference.com/w/cpp/numeric/math/isnan

Please note that this is incompatible with -fast-math if you use g++, see below for other suggestions.

Other solutions: if you using non C++11 compliant tools

For C99, in C, this is implemented as a macro isnan(c)that returns an int value. The type of x shall be float, double or long double.

Various vendors may or may not include or not a function isnan().

The supposedly portable way to check for NaN is to use the IEEE 754 property that NaN is not equal to itself: i.e. x == x will be false for x being NaN.

However the last option may not work with every compiler and some settings (particularly optimisation settings), so in last resort, you can always check the bit pattern ...

If this issue happens for the HTTPS repository, f.e. https://repo.spring.io/milestone you can just try to replace with non secured: http://repo.spring.io/milestone. And that's it

On IntelliJ go to Preference -> Build, Execution, Deployment -> Build Tools -> Maven. Turn on the checkbox for "Always update snapshots" apply and save changes then do mvn clean install

If you simply need to view the table and run queries on it you can use this third party sdf viewer. It is a lightweight viewer that has all the basic functionalities and is ready to use after install.

and ofcourse, its Free.

If you are using Eloquent, in your model put:

public function getPriceAttribute($price)
{
    return $this->attributes['price'] = sprintf('U$ %s', number_format($price, 2));
}

Where getPriceAttribute is your field on database. getSomethingAttribute.

You have given permission to perform commands on objects inside the S3 bucket, but you have not given permission to perform any actions on the bucket itself.

Slightly modifying your policy would look like this:

{
  "Version": "version_id",
  "Statement": [
    {
        "Sid": "some_id",
        "Effect": "Allow",
        "Action": [
            "s3:*"
        ],
        "Resource": [
            "arn:aws:s3:::bucketname",
            "arn:aws:s3:::bucketname/*"
        ]
    }
  ] 
}

However, that probably gives more permission than is needed. Following the AWS IAM best practice of Granting Least Privilege would look something like this:

{
  "Version": "2012-10-17",
  "Statement": [
      {
          "Effect": "Allow",
          "Action": [

Select Custom Structure in permalinks and add /%category%/%postname%/ after your domain. Adding "/" to the category base doesn't work, you have to add a period/dot. I wrote a tutorial for this here: remove category from URL tutorial

You could get the first element in the array_keys() function as well. Or array_search() the keys for the "index" of a key. If you are inside a foreach loop, the simple incrementing counter (suggested by kip or cletus) is probably your most efficient method though.

<?php
   $array = array('test', '1', '2');
   $keys = array_keys($array);
   var_dump($keys[0]); // int(0)

   $array = array('test'=>'something', 'test2'=>'something else');
   $keys = array_keys($array);

   var_dump(array_search("test2", $keys)); // int(1)     
   var_dump(array_search("test3", $keys)); // bool(false)

Use .net inbuilt class JavaScriptSerializer

  JavaScriptSerializer js = new JavaScriptSerializer();
  string json = js.Serialize(obj);

The WebRequest object seems like too much work for me. I prefer to use the WebClient control.

To use this function you just need to create two NameValueCollections holding your parameters and request headers.

Consider the following function:

    private static string DoGET(string URL,NameValueCollection QueryStringParameters = null, NameValueCollection RequestHeaders = null)
    {
        string ResponseText = null;
        using (WebClient client = new WebClient())
        {
            try
            {
                if (RequestHeaders != null)
                {
                    if (RequestHeaders.Count > 0)
                    {
                        foreach (string header in RequestHeaders.AllKeys)
                            client.Headers.Add(header, RequestHeaders[header]);
                    }
                }
                if (QueryStringParameters != null)
                {
                    if (QueryStringParameters.Count > 0)
                    {
                        foreach (string parm in QueryStringParameters.AllKeys)
                            client.QueryString.Add(parm, QueryStringParameters[parm]);
                    }
                }
                byte[] ResponseBytes = client.DownloadData(URL);
                ResponseText = Encoding.UTF8.GetString(ResponseBytes);
            }
            catch (WebException exception)
            {
                if (exception.Response != null)
                {
                    var responseStream = exception.Response.GetResponseStream();

                    if (responseStream != null)
                    {
                        using (var reader = new StreamReader(responseStream))
                        {
                            Response.Write(reader.ReadToEnd());
                        }
                    }
                }
            }
        }
        return ResponseText;
    }

Add your querystring parameters (if required) as a NameValueCollection like so.

        NameValueCollection QueryStringParameters = new NameValueCollection();
        QueryStringParameters.Add("id", "123");
        QueryStringParameters.Add("category", "A");

Add your http headers (if required) as a NameValueCollection like so.

        NameValueCollection RequestHttpHeaders = new NameValueCollection();
        RequestHttpHeaders.Add("Authorization", "Basic bGF3c2912XBANzg5ITppc2ltCzEF");

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

I Reject Embedded JDK ( in 32bit ) because embedded JDK is 64bit

Right click your Project -> Open Module Setting -> SDK Location -> Uncheck Use embedded JDk then set your JDK Path, eg in Ubuntu /usr/lib/jvm/java-8-openjdk-i386

I was having the same problem where the browser was unable to find the font files, and my issue was due to exclusions in my .htaccess file that was whitelisting files that shouldn't be sent to index.php for processing. As the font file couldn't be loaded the characters were replaced with BLOB.

RewriteCond %{REQUEST_URI} !\.(jpg|png|gif|svg|css|js|ico|rss|xml|json)$
RewriteCond %{REQUEST_URI} !-d
RewriteRule ^ index.php [L,QSA]

As you can see, files like images, rss, and xml are excluded from the rewrite, but the font files are .woff and .woff2 files, so these also needed adding to the whitelist.

RewriteCond %{REQUEST_URI} !\.(jpg|png|gif|svg|css|js|ico|rss|xml|json|woff|woff2)$
RewriteCond %{REQUEST_URI} !-d
RewriteRule ^ index.php [L,QSA]

Adding woff and woff2 to the whitelist allows the font files to be loaded, and the glyphicons should then display properly.

This is how I accomplished reading a table in javascript. Basically I drilled down into the rows and then I was able to drill down into the individual cells for each row. This should give you an idea

//gets table
var oTable = document.getElementById('myTable');

//gets rows of table
var rowLength = oTable.rows.length;

//loops through rows    
for (i = 0; i < rowLength; i++){

   //gets cells of current row
   var oCells = oTable.rows.item(i).cells;

   //gets amount of cells of current row
   var cellLength = oCells.length;

   //loops through each cell in current row
   for(var j = 0; j < cellLength; j++){
      /* get your cell info here */
      /* var cellVal = oCells.item(j).innerHTML; */
   }
}

UPDATED - TESTED SCRIPT

<table id="myTable">
    <tr>
        <td>A1</td>
        <td>A2</td>
        <td>A3</td>
    </tr>
    <tr>
        <td>B1</td>
        <td>B2</td>
        <td>B3</td>
    </tr>
</table>
<script>
    //gets table
    var oTable = document.getElementById('myTable');

    //gets rows of table
    var rowLength = oTable.rows.length;

    //loops through rows    
    for (i = 0; i < rowLength; i++){

      //gets cells of current row  
       var oCells = oTable.rows.item(i).cells;

       //gets amount of cells of current row
       var cellLength = oCells.length;

       //loops through each cell in current row
       for(var j = 0; j < cellLength; j++){

              // get your cell info here

              var cellVal = oCells.item(j).innerHTML;
              alert(cellVal);
           }
    }
</script>

I usually create log table with a stored procedure to log to it. The call the logging procedure wherever needed from the procedure under development.

Looking at other posts on this same question, it seems like a common practice, although there are some alternatives.

To verify:

import sys
print(sys.path)

Selected path should be listed here.

This is how I solved this issue:

1. Change the .env file as follow

2. Never forget to restart the server after you change the .env file

I was getting this problem due to pack200 mangling a class file. A bit of searching turned this java bug up. Basically, setting --effort=4 caused the problem to go away.

Using java 1.5.0_17 (though it cropped up in every single variant of java 1.5 I tried it in).

I had to do following:

1. Create an app in google play console

2.Go to App releases -> Manage production -> Create release

3.Click continue on Google Play App Signing

4.Create upload certificate by running "keytool -genkey -v -keystore c:\path\to\cert.keystore -alias uploadKey -keyalg RSA -keysize 2048 -validity 10000"

5.Sign your apk with generated certificate (c:\path\to\cert.keystore)

6.Upload signed apk in App releases -> Manage production -> Edit release

7.By uploading apk, certificate generated in step 4 has been added to App Signing certificates and became your signing cert for all future builds.

Fell into the same trouble with inlining functions into so libraries. It seems that inlined functions are not compiled into the library. as a result the linker puts out a "undefined reference" error, if a executable wants to use the inlined function of the library. (happened to me compiling Qt source with gcc 4.5.

This one works:

<input type="button" value="test" onclick="alert('hey'); alert('ho');" />

And this one too:

function Hey()
{
    alert('hey');
}

function Ho()
{
    alert('ho');
}

.

<input type="button" value="test" onclick="Hey(); Ho();" />

So the answer is - yes you can :) However, I'd recommend to use unobtrusive JavaScript.. mixing js with HTML is just nasty.

I had a similar problem - authenticate device and user at device. I used a Cookie header alongside an Authorization: Bearer... header. One header authenticated the device, the other authenticated the user. I used a Cookie header because these are commonly used for authentication.

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

Am adding few things related to jenkins configuration files storage.

As per my understanding all config file stores in the machine or OS that you have installed jenkins.

The jobs you are going to create in jenkins will be stored in jenkins server and you can find the config.xml etc., here.

After jenkins installation you will find jenkins workspace in server.

*cd>jenkins/jobs/`
cd>jenkins/jobs/$ls
   job1 job2 job3 config.xml ....*

Try something like this: Create the final object table, tmpFerdeen with the structure of the union.

Then

INSERT INTO tmpFerdeen (
SELECT top(100)* 
FROM Customers
UNION All
SELECT top(100)* 
FROM CustomerEurope
UNION All
SELECT top(100)* 
FROM CustomerAsia
UNION All
SELECT top(100)* 
FROM CustomerAmericas
)

NOTE: While my advice was true many years ago, Oracle's optimizer has improved so that the location of the where definitely no longer matters here. However preferring UNION ALL vs UNION will always be true, and portable SQL should avoid depending on optimizations that may not be in all databases.

Short answer, you want the WHERE before the UNION and you want to use UNION ALL if at all possible. If you are using UNION ALL then check the EXPLAIN output, Oracle might be smart enough to optimize the WHERE condition if it is left after.

The reason is the following. The definition of a UNION says that if there are duplicates in the two data sets, they have to be removed. Therefore there is an implicit GROUP BY in that operation, which tends to be slow. Worse yet, Oracle's optimizer (at least as of 3 years ago, and I don't think it has changed) doesn't try to push conditions through a GROUP BY (implicit or explicit). Therefore Oracle has to construct larger data sets than necessary, group them, and only then gets to filter. Thus prefiltering wherever possible is officially a Good Idea. (This is, incidentally, why it is important to put conditions in the WHERE whenever possible instead of leaving them in a HAVING clause.)

Furthermore if you happen to know that there won't be duplicates between the two data sets, then use UNION ALL. That is like UNION in that it concatenates datasets, but it doesn't try to deduplicate data. This saves an expensive grouping operation. In my experience it is quite common to be able to take advantage of this operation.

Since UNION ALL does not have an implicit GROUP BY in it, it is possible that Oracle's optimizer knows how to push conditions through it. I don't have Oracle sitting around to test, so you will need to test that yourself.

use [\\W+] or "[^a-zA-Z0-9]" as regex to match any special characters and also use String.replaceAll(regex, String) to replace the spl charecter with an empty string. remember as the first arg of String.replaceAll is a regex you have to escape it with a backslash to treat em as a literal charcter.

          String c= "hjdg$h&jk8^i0ssh6";
        Pattern pt = Pattern.compile("[^a-zA-Z0-9]");
        Matcher match= pt.matcher(c);
        while(match.find())
        {
            String s= match.group();
        c=c.replaceAll("\\"+s, "");
        }
        System.out.println(c);

For things like numbers (decimal points, commas in amounts), they are usually preferred in the specific culture.

A appropriate way to do this would be set it at the culture level (for German) like this:

Thread.CurrentThread.CurrentCulture.NumberFormat = new CultureInfo("de").NumberFormat;

I assume you mean list and not array? There is such a thing as an array in Python, but more often than not you want a list instead of an array.

The way to check if a list contains a value is to use in:

if paid[j] in d:
    # ...

You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.

I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).

To install it, you can either download it from the linked website or use the command:

pip install pyinstaller

...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:

pyinstaller myscript.py

You can find more information about how to use Pyinstaller and customize the build process via the documentation.

You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.

Why not use the PDFMergerUtility of pdfbox?

PDFMergerUtility ut = new PDFMergerUtility();
ut.addSource(...);
ut.addSource(...);
ut.addSource(...);
ut.setDestinationFileName(...);
ut.mergeDocuments();

It's very simple.

You can call it from anywhere in APP.

$out = new \Symfony\Component\Console\Output\ConsoleOutput();
$out->writeln("Hello from Terminal");

I recently came across this problem myself.

<!--Instead of using input-->
<input type="submit"/>
<!--Use button-->
<button type="submit">
<!--You can then attach your custom CSS to the button-->

Hope that helps.

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.

Since converting unsigned values use to represent positive numbers converting it can be done by setting the most significant bit to 0. Therefore a program will not interpret that as a Two`s complement value. One caveat is that this will lose information for numbers that near max of the unsigned type.

template <typename TUnsigned, typename TSinged>
TSinged UnsignedToSigned(TUnsigned val)
{
    return val & ~(1 << ((sizeof(TUnsigned) * 8) - 1));
}

\d+

\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"

As to the "problem" of what key to press to close it, I (and thousands of others, I'm sure) simply use input("Press Enter to close").

This is just an explanation not addressed in other answers

At least in recent versions of Mysql, your first query is not committed.

If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.

What's going on?

When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.

So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE, UPDATE, INSERT or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).

That's why the solution involves declaring handlers to immediately ROLLBACK when an error happens.

Extra

Inside the handler you can also re-raise the error using RESIGNAL, otherwise the stored procedure executes "Successfully"

BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
        BEGIN
            ROLLBACK;
            RESIGNAL;
        END;

    START TRANSACTION;
        #.. Query 1 ..
        #.. Query 2 ..
        #.. Query 3 ..
    COMMIT;
END

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

now 2020, i am face to same question, but for this old question, there are so many new answer, just list some of it:

• this is webpack.config.js

plugins: [
        new HtmlWebpackPlugin({
            // 1. title is the parameter, you can use in ejs template
            templateParameters:{
                title: JSON.stringify(someting: 'something'),
            },
        }), 


        //2. BUILT_AT is a parameter too. can use it.
        new webpack.DefinePlugin({
            BUILT_AT: webpack.DefinePlugin.runtimeValue(Date.now,"some"),

        }),

        //3. for webpack5, you can use global variable: __webpack_hash__
        //new webpack.ExtendedAPIPlugin()
    ],
    //4. this is not variable, this is module, so use 'import tt' to use it.
    externals: { 
        'ex_title': JSON.stringify({
            tt: 'eitentitle',
        })
    },

the 4 ways only basic, there are even more ways that i believe. but i think maybe this 4ways is the most simple.

I had ran into this similar problem as well. In my case, my resolution is quite different. Here's my spring context xml file:

...
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd">
...

I'm not specifying any xsd version as I want spring to use the latest xsd version inside spring dependencies. The spring version my application used was spring-beans-4.3.1.RELEASE.jar:4.3.1.RELEASE and when I assembly my application into jar, all spring dependencies exist in my classpath. However, I received following error during startup of my spring application context:

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

After some hard time troubleshooting, I found the issue is due to the index.list inside the META-INF folder of my jar file. With index.list file, spring namespace handlers cannot be located to parse the spring application context xml correctly. You can read more about this spring issue SPR-5705

By removing indexing from my maven-jar-plugin, I manage to resolve the issue. Hope this will save some times for people having the same problem.

Combine @vincsilver and @jdigital's answers with some modifications,

1. export .reg to current directory
2. add date mark

code:

set TODAY=%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%

regedit /e "%CD%\user_env_variables[%TODAY%].reg" "HKEY_CURRENT_USER\Environment"
regedit /e "%CD%\global_env_variables[%TODAY%].reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

Output would like:

global_env_variables[2017-02-14].reg

I know Edwin answered it above but his only prints one document. I use this code to print all files from a given directory.

public void PrintAllFiles()
{
    System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo();
    info.Verb = "print";
    System.Diagnostics.Process p = new System.Diagnostics.Process();
    //Load Files in Selected Folder
    string[] allFiles = System.IO.Directory.GetFiles(Directory);
    foreach (string file in allFiles)
    {
        info.FileName = @file;
        info.CreateNoWindow = true;
        info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
         p.StartInfo = info;
        p.Start();
    }
    //p.Kill(); Can Create A Kill Statement Here... but I found I don't need one
    MessageBox.Show("Print Complete");
}

It essentually cycles through each file in the given directory variable Directory - > for me it was @"C:\Users\Owner\Documents\SalesVaultTesting\" and prints off those files to your default printer.

(1) This just happened to me, and I thought it was interesting how it happened. Basically I had copied the folder to a new location and modified it, forgetting that it would bring along all the hidden .svn directories. Once you realize how it happens it is easier to avoid in the future.

(2) Removing the .svn directories is the solution, but you have to do it recursively all the way down the directory tree. The easiest way to do that is:

find troublesome_folder -name .svn -exec rm -rf {} \;

IF EXISTS() is semantically incorrect. EXISTS condition can be used only inside a SQL statement. So you might rewrite your pl/sql block as follows:

declare
  l_exst number(1);
begin
  select case 
           when exists(select ce.s_regno 
                         from courseoffering co
                         join co_enrolment ce
                           on ce.co_id = co.co_id
                        where ce.s_regno=403 
                          and ce.coe_completionstatus = 'C' 
                          and ce.c_id = 803
                          and rownum = 1
                        )
           then 1
           else 0
         end  into l_exst
  from dual;

  if l_exst = 1 
  then
    DBMS_OUTPUT.put_line('YES YOU CAN');
  else
    DBMS_OUTPUT.put_line('YOU CANNOT'); 
  end if;
end;

Or you can simply use count function do determine the number of rows returned by the query, and rownum=1 predicate - you only need to know if a record exists:

declare
  l_exst number;
begin
   select count(*) 
     into l_exst
     from courseoffering co
          join co_enrolment ce
            on ce.co_id = co.co_id
    where ce.s_regno=403 
      and ce.coe_completionstatus = 'C' 
      and ce.c_id = 803
      and rownum = 1;

  if l_exst = 0
  then
    DBMS_OUTPUT.put_line('YOU CANNOT');
  else
    DBMS_OUTPUT.put_line('YES YOU CAN');
  end if;
end;

Would you be satisfied with a Map from Jackson?

ObjectMapper objectMapper = new ObjectMapper();
Map<String, Object> map = objectMapper.readValue(jsonString, new TypeReference<HashMap<String,Object>>(){});

Or maybe a JsonNode?

JsonNode jsonNode = objectMapper.readTree(String jsonString) 

Absolutely valid.

    <form action="javascript:alert('Hello there, I am being submitted');">
        <button type="submit">
            Let's do it
        </button>
    </form>
    <!-- Tested in Firefox, Chrome, Edge and Safari -->

So for a short answer: yes, this is an option, and a nice one. It says "when submitted, please don't go anywhere, just run this script" - quite to the point.

A minor improvement

To let the event handler know which form we're dealing with, it would seem an obvious way to pass on the sender object:

    <form action="javascript:myFunction(this)">  <!-- should work, but it won't -->

But instead, it will give you undefined. You can't access it because javascript: links live in a separate scope. Therefore I'd suggest the following format, it's only 13 characters more and works like a charm:

    <form action="javascript:;" onsubmit="myFunction(this)">  <!-- now you have it! -->

... now you can access the sender form properly. (You can write a simple "#" as action, it's quite common - but it has a side effect of scrolling to the top when submitting.)

Again, I like this approach because it's effortless and self-explaining. No "return false", no jQuery/domReady, no heavy weapons. It just does what it seems to do. Surely other methods work too, but for me, this is The Way Of The Samurai.

A note on validation

Forms only get submitted if their onsubmit event handler returns something truthy, so you can easily run some preemptive checks:

    <form action="/something.php" onsubmit="return isMyFormValid(this)">

Now isMyFormValid will run first, and if it returns false, server won't even be bothered. Needless to say, you will have to validate on server side too, and that's the more important one. But for quick and convenient early detection this is fine.

For Windows:

1. Open the start menu

2. Type windows+R or open "Run"

3. Execute the following command:

    chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security
   

For Mac:

1. Go to Terminal

2. Execute the following command:

    open /Applications/Google\ Chrome.app --args --user-data-dir="/var/tmp/Chrome dev session" --disable-web-security
   

A new web security disabled chrome browser should open with the following message:

For Mac

If you want to open new instance of web security disabled Chrome browser without closing existing tabs then use below command

open -na Google\ Chrome --args --user-data-dir=/tmp/temporary-chrome-profile-dir --disable-web-security

It will open new instance of web security disabled Chrome browser as shown below

- Here its more about the coding style than being the functionality....

- The 1st option is very clear, but then the 2nd one is quite elegant... no offense, its just my view..

Should be :

<h2 class="col-md-4 col-md-offset-1">Browse.</h2>
<h2 class="col-md-4 col-md-offset-2">create.</h2>
<h2 class="col-md-4 col-md-offset-3">share.</h2>

you can use solutions without adding "Access-Control-Allow-Origin": "*", if your server is already using Proxy gateway this issue will not happen because the front and backend will be route in the same IP and port in client side but for development, you need one of this three solution if you don't need extra code 1- simulate the real environment by using a proxy server and configure the front and backend in the same port

2- if you using Chrome you can use the extension called Allow-Control-Allow-Origin: * it will help you to avoid this problem

3- you can use the code but some browsers versions may not support that so try to use one of the previous solutions

the best solution is using a proxy like ngnix its easy to configure and it will simulate the real situation of the production deployment

Seems pretty straightforward, according to the docs on the page you linked (emphasis mine).

requests.get(url, params=None, headers=None, cookies=None, auth=None, timeout=None)

Sends a GET request. Returns Response object.

Parameters:

• url – URL for the new Request object.
• params – (optional) Dictionary of GET Parameters to send with the Request.
• headers – (optional) Dictionary of HTTP Headers to send with the Request.
• cookies – (optional) CookieJar object to send with the Request.
• auth – (optional) AuthObject to enable Basic HTTP Auth.
• timeout – (optional) Float describing the timeout of the request.

Also, there is the solution for IvyDE users. Right click on project -> Ivy -> resolve It's necessary to set ivy.mirror property in build.properties

A trick that works is to position box #2 with position: absolute instead of position: relative. We usually put a position: relative on an outer box (here box #2) when we want an inner box (here box #3) with position: absolute to be positioned relative to the outer box. But remember: for box #3 to be positioned relative to box #2, box #2 just need to be positioned. With this change, we get:

And here is the full code with this change:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
        <style type="text/css">

            /* Positioning */
            #box1 { overflow: hidden }
            #box2 { position: absolute }
            #box3 { position: absolute; top: 10px }

            /* Styling */
            #box1 { background: #efe; padding: 5px; width: 125px }
            #box2 { background: #fee; padding: 2px; width: 100px; height: 100px }
            #box3 { background: #eef; padding: 2px; width: 75px; height: 150px }

        </style>
    </head>
    <body>
        <br/><br/><br/>
        <div id="box1">
            <div id="box2">
                <div id="box3"/>
            </div>
        </div>
    </body>
</html>

You'd use a self-join on a table that "refers" to itself - e.g. a table of employees where managerid is a foreign-key to employeeid on that same table.

Example:

SELECT E.name, ME.name AS manager
FROM dbo.Employees E
LEFT JOIN dbo.Employees ME
ON ME.employeeid = E.managerid

There are two ways to take a photo:

1 - Using an Intent to make a photo

2 - Using the camera API

I think you should use the second way and there is a sample code here for two of them.

System.Environment.Exit(0); in view model would work.

As to me, i need to caffe to my python path. I can add it's path to the file /home/xy/.bashrc by add

export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH.

to my /home/xy/.bashrc file.

But when I use pycharm, the path is still not in.

So I can add path to PYTHONPATH variable, by run -> edit Configuration.

Tracking individual changed items in a list

If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal, oldVal) {
      // Handle changes here!
      // NOTE: For mutated objects, newVal and oldVal will be identical.
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

If your list isn't populated straight away (like in the original question), you can move the logic out of created to wherever needed, e.g. inside the .then() block.

Watching a changing list

If your list itself updates to have new or removed items, I've developed a useful pattern that "shallow" watches the list itself, and dynamically watches/unwatches items as the list changes:

// NOTE: This example uses Lodash (_.differenceBy and _.pull) to compare lists
//       and remove list items. The same result could be achieved with lots of
//       list.indexOf(...) if you need to avoid external libraries.

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
    watchTracker: [],
  },
  methods: {
    handleChange (newVal, oldVal) {
      // Handle changes here!
      console.log(newVal);
    },
    updateWatchers () {
      // Helper function for comparing list items to the "watchTracker".
      const getItem = (val) => val.item || val;

      // Items that aren't already watched: watch and add to watched list.
      _.differenceBy(this.list, this.watchTracker, getItem).forEach((item) => {
        const unwatch = this.$watch(() => item, this.handleChange, {deep: true});
        this.watchTracker.push({ item: item, unwatch: unwatch });
        // Uncomment below if adding a new item to the list should count as a "change".
        // this.handleChange(item);
      });

      // Items that no longer exist: unwatch and remove from the watched list.
      _.differenceBy(this.watchTracker, this.list, getItem).forEach((watchObj) => {
        watchObj.unwatch();
        _.pull(this.watchTracker, watchObj);
        // Optionally add any further cleanup in here for when items are removed.
      });
    },
  },
  watch: {
    list () {
      return this.updateWatchers();
    },
  },
  created () {
    return this.updateWatchers();
  },
});

Changing XAMPP Default Port: If you want to get XAMPP up and running, you should consider changing the port from the default 80 to say 7777.

• In the XAMPP Control Panel, click on the Apache – Config button which is located next to the ‘Logs’ button.

• Select ‘Apache (httpd.conf)’ from the drop down. (Notepad should open)

• Do Ctrl+F to find ’80’ and change line Listen 80 to Listen 7777

• Find again and change line ServerName localhost:80 to ServerName localhost:7777

• Save and re-start Apache. It should be running by now.

The only demerit to this technique is, you have to explicitly include the port number in the localhost url. Rather than http://localhost it becomes http://localhost:7777.

It is because display:inline-block takes into account white-space in the html. If you remove the white-space between the div's it works as expected. Live Example: http://jsfiddle.net/XCDsu/4/

<div id="col1">content</div><div id="col2">content</div>

After doing an insert into a table with an identity column, you can reference @@IDENTITY to get the value: http://msdn.microsoft.com/en-us/library/aa933167%28v=sql.80%29.aspx

Make sure that you aren't clicking on "Run unnamed" from 'run' tab. You must click on "run ". Or just click the green shortcut button.

If you want to print the text of a UITableViewCell according to its matching NSIndexPath, you have to use UITableViewDelegate's tableView:didSelectRowAtIndexPath: method and get a reference of the selected UITableViewCell with UITableView's cellForRowAtIndexPath: method.

For example:

import UIKit

class TableViewController: UITableViewController {

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 4
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)

        switch indexPath.row {
        case 0: cell.textLabel?.text = "Bike"
        case 1: cell.textLabel?.text = "Car"
        case 2: cell.textLabel?.text = "Ball"
        default: cell.textLabel?.text = "Boat"
        }

        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        let selectedCell = tableView.cellForRowAtIndexPath(indexPath)
        print(selectedCell?.textLabel?.text)
        // this will print Optional("Bike") if indexPath.row == 0
    }

}

However, for many reasons, I would not encourage you to use the previous code. Your UITableViewCell should only be responsible for displaying some content given by a model. In most cases, what you want is to print the content of your model (could be an Array of String) according to a NSIndexPath. By doing things like this, you will separate each element's responsibilities.

Thereby, this is what I would recommend:

import UIKit

class TableViewController: UITableViewController {

    let toysArray = ["Bike", "Car", "Ball", "Boat"]

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return toysArray.count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
        cell.textLabel?.text = toysArray[indexPath.row]
        return cell
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        let toy = toysArray[indexPath.row]
        print(toy)
        // this will print "Bike" if indexPath.row == 0
    }

}

As you can see, with this code, you don't have to deal with optionals and don't even need to get a reference of the matching UITableViewCell inside tableView:didSelectRowAtIndexPath: in order to print the desired text.

I'm using this lib to access nested dict keys

https://github.com/mewwts/addict

 import requests
 from addict import Dict
 r = requests.get('http://api.zippopotam.us/us/ma/belmont')
 j = Dict(r.json())

 print j.state
 print j.places[1]['post code']  # only work with keys without '-', space, or starting with number 

I understand that this is a response to an old post-

I like the If() function combined with Index()/Match():

=IF(B2>0,"x",INDEX($H$2:$I$9,MATCH(A2,$H$2:$H$9,0),2))

The if function compare what is in column b and if it is greater than 0, it returns x, if not it uses the array (table of information) identified by the Index() function and selected by Match() to return the value that a corresponds to.

The Index array has the absolute location set $H$2:$I$9 (the dollar signs) so that the place it points to will not change as the formula is copied. The row with the value that you want returned is identified by the Match() function. Match() has the added value of not needing a sorted list to look through that Vlookup() requires. Match() can find the value with a value: 1 less than, 0 exact, -1 greater than. I put a zero in after the absolute Match() array $H$2:$H$9 to find the exact match. For the column that value of the Index() array that one would like returned is entered. I entered a 2 because in my array the return value was in the second column. Below my index array looked like this:

32   1420

36   1650

40   1790

44   1860

55   2010

The value in your 'a' column to search for in the list is in the first column in my example and the corresponding value that is to be return is to the right. The look up/reference table can be on any tab in the work book - or even in another file. -Book2 is the file name, and Sheet2 is the 'other tab' name.

=IF(B2>0,"x",INDEX([Book2]Sheet2!$A$1:$B$8,MATCH(A2,[Book2]Sheet2!$A$1:$A$8,0),2))

If you do not want x return when the value of b is greater than zero delete the x for a 'blank'/null equivalent or maybe put a 0 - not sure what you would want there.

Below is beginning of the function with the x deleted.

=IF(B2>0,"",INDEX...

If you want to revert changes made to your working copy, do this:

git checkout .

If you want to revert changes made to the index (i.e., that you have added), do this. Warning this will reset all of your unpushed commits to master!:

git reset

If you want to revert a change that you have committed, do this:

git revert <commit 1> <commit 2>

If you want to remove untracked files (e.g., new files, generated files):

git clean -f

Or untracked directories (e.g., new or automatically generated directories):

git clean -fd

You don't really need jQuery for this as there is a Media API that provides you with all you need.

var video = document.getElementById('myVideo');
video.src = 'my_video_' + value + '.ogg';
video.load();

The Media API also contains a load() method which: "Causes the element to reset and start selecting and loading a new media resource from scratch."

(Ogg isn't the best format to use, as it's only supported by a limited number of browsers. I'd suggest using WebM and MP4 to cover all major browsers - you can use the canPlayType() function to decide on which one to play).

You can then wait for either the loadedmetadata or loadeddata (depending on what you want) events to fire:

video.addEventListener('loadeddata', function() {
   // Video is loaded and can be played
}, false);

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

Well you could use the <Directory> tag for example:

<Directory /inscription>
  <Files log.txt>
    Order allow,deny
    Deny from all
  </Files>
</Directory>

Do not use ./ because if you just use / it looks at the root directory of your site.

Even I got the same problem when I've first installed Anaconda. It said 'conda' command not found.

So I've just setup two values[added two new paths of Anaconda] system environment variables in the PATH variable which are: C:\Users\mshas\Anaconda2\ & C:\Users\mshas\Anaconda2\Scripts

Lot of people forgot to add the second variable which is "Scripts" just add that then 'conda' command works.

I think you should do

for index, row in result: 

If you wanna access by name.

Use the following code

$("#modal").trigger('click');

As mentioned you should assign the connection and you should preferably also use sql parameters instead, so your command assignment would read:

    // 3. Pass the connection to a command object
    SqlCommand cmd=new SqlCommand ("insert into time(project,iteration) values (@project, @iteration)", conn); // ", conn)" added
    cmd.Parameters.Add("project", System.Data.SqlDbType.NVarChar).Value = this.name1.SelectedValue;
    cmd.Parameters.Add("iteration", System.Data.SqlDbType.NVarChar).Value = this.name1.SelectedValue;

    //
    // 4. Use the connection
    //

By using parameters you avoid SQL injection and other problematic typos (project names like "myproject's" is an example).

You can do the following if you already know the number of fields of the input:

client_name = raw_input("Enter you first and last name: ")
first_name, last_name = client_name.split() 

and in case you want to iterate through the fields separated by spaces, you can do the following:

some_input = raw_input() # This input is the value separated by spaces
for field in some_input.split():
    print field # this print can be replaced with any operation you'd like
    #             to perform on the fields.

A more generic use of the "split()" function would be:

    result_list = some_string.split(DELIMITER)

where DELIMETER is replaced with the delimiter you'd like to use as your separator, with single quotes surrounding it.

An example would be:

    result_string = some_string.split('!')    

The code above takes a string and separates the fields using the '!' character as a delimiter.

While you are switching, switch to PDO instead of mysqli, It helps you write database agnositc code and have better features for prepared statements.

http://www.php.net/pdo

Bindparam for PDO: http://se.php.net/manual/en/pdostatement.bindparam.php

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->bindParam(':value1', 'foo');
$sth->bindParam(':value2', 'bar');
$sth->execute();

or:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = ? && field2 = ?");
$sth->bindParam(1, 'foo');
$sth->bindParam(2, 'bar');
$sth->execute();

or execute with the parameters as an array:

$sth = $dbh->prepare("SELECT * FROM tablename WHERE field1 = :value1 && field2 = :value2");
$sth->execute(array(':value1' => 'foo' , ':value2' => 'bar'));

It will be easier for you if you would like your application to be able to run on different databases in the future.

I also think you should invest some time in using some of the classes from Zend Framwework whilst working with PDO. Check out their Zend_Db and more specifically [Zend_Db_Factory][2]. You do not have to use all of the framework or convert your application to the MVC pattern, but using the framework and reading up on it is time well spent.

$result = mysql_query($query) or die("Data not found."); 
$rows=array(); 
while($r=mysql_fetch_assoc($result))
{ 
$rows[]=$r;
}
header("Content-type:application/json"); 
echo json_encode($rows);

Here is a good tutorial with code. Let me know if it works for you! This is also a good tutorial.

EDIT

In This example, all you need to do is add this line:

gallery.setSelection(1);

after setting the adapter to gallery object, that is this line:

gallery.setAdapter(new ImageAdapter(this));

UPDATE1

Alright, I got your problem. This open source library is your solution. I also have used it for one of my projects. Hope this will solve your problem finally.

UPDATE2:

I would suggest you to go through this tutorial. You might get idea. I think I got your problem, you want the horizontal scrollview with snap. Try to search with that keyword on google or out here, you might get your solution.

Be careful that when you using: curl -H "Authorization: token_str" http://www.example.com

token_str and Authorization must be separated by white space, otherwise server-side will not get the HTTP_AUTHORIZATION environment.

I am having problems with stdin/stout - when payload size exceeds several kilobytes it hangs. I need to call Python functions not only with some short arguments, but with a custom payload that could be big.

A while ago, I wrote a virtual actor library that allows to distribute task on different machines via Redis. To call Python code, I added functionality to listen for messages from Python, process them and return results back to .NET. Here is a brief description of how it works.

It works on a single machine as well, but requires a Redis instance. Redis adds some reliability guarantees - payload is stored until a worked acknowledges completion. If a worked dies, the payload is returned to a job queue and then is reprocessed by another worker.

IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'MyType')

sys.types... they aren't schema-scoped objects so won't be in sys.objects

Update, Mar 2013

You can use TYPE_ID too

You can simply use:

""+ Modes.mode1

Did you actually set up your specific user? The walkthrough setup guide in AWS explains how to set a default user, and then how to set up additional users. If you didn't complete the full setup, you'll just have a default block and your myName won't have been created..

The below 'd help you to add the cert to the Root Store-

certutil -enterprise -f -v -AddStore "Root" <Cert File path>

This worked for me perfectly.

if you are using the "Google Cloud Message" to receive push notifications with "PendingIntent" class, the following code displays the notification in the action bar only.

Clicking the notification no activity will be created, the last active activity is restored retaining current state without problems.

Intent notificationIntent = new Intent(this, ActBase.class); **notificationIntent.setAction(Intent.ACTION_MAIN); notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);** PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("Localtaxi") .setVibrate(vibrate) .setStyle(new NotificationCompat.BigTextStyle().bigText(msg)) .setAutoCancel(true) .setOnlyAlertOnce(true) .setContentText(msg);

mBuilder.setContentIntent(contentIntent);

NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

Ciao!

It doesn't work on Ubuntu 16.04, it seems that some libraries have been forgotten in the python installation package on this one. You should use package manager instead.

Solution

Uninstall matplotlib from pip then install it again with apt-get

python 2:

sudo pip uninstall matplotlib
sudo apt-get install python-matplotlib

python 3:

sudo pip3 uninstall matplotlib
sudo apt-get install python3-matplotlib

Alternate solution of the values check

//Duplicate Title Entry 
    $.each(ar , function (i, val) {
        if ( jQuery("input:first").val()== val) alert('VALUE FOUND'+Valuecheck);
  });

<select name="FakeName" id="Fake-ID" aria-required="true" required>  <?php $options=nl2br(file_get_contents("employees.txt")); $options=explode("<br />",$options);  foreach ($options as $item_array) { echo "<option value='".$item_array"'>".$item_array"</option>";  } ?> </select> 

EDIT The iOS 11 way to work out where to put the top of your view content is UIView's safeAreaLayoutGuide See UIView Documentation.

DEPRECATED ANSWER If you're targeting iOS 7+, The documentation for UIViewController advises that the viewController's topLayoutGuide property gives you the bottom of the status bar, or the bottom of the navigation bar, if it's also visible. That may be of use, and is certainly less hack than many of the previous solutions.

list.ForEach(x=>Console.WriteLine(x));

In 2018,

$('#datepicker').datepicker({
    format: "yyyy",
    weekStart: 1,
    orientation: "bottom",
    language: "{{ app.request.locale }}",
    keyboardNavigation: false,
    viewMode: "years",
    minViewMode: "years"
});

I've found this to work:

var element1 = document.createElement("input");
element1.type = "hidden";
element1.value = "10";
element1.name = "a";
document.getElementById("chells").appendChild(element1);

If you don't want to leave base R, here's a fairly succinct and expressive possibility:

x <- q.data$string
lengths(regmatches(x, gregexpr("a", x)))
# [1] 2 1 0

This is the main difference between username variable and whoami command:

C:\Users\user.name>echo %username%
user.name

C:\Users\user.name>whoami
domain\user.name

DOMAIN = bios name of the domain (not fqdn)

That is not how the PUBLIC_URL variable is used. According to the documentation, you can use the PUBLIC_URL in your HTML:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

Or in your JavaScript:

render() {
  // Note: this is an escape hatch and should be used sparingly!
  // Normally we recommend using `import` for getting asset URLs
  // as described in “Adding Images and Fonts” above this section.
  return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;
}

The PUBLIC_URL is not something you set to a value of your choosing, it is a way to store files in your deployment outside of Webpack's build system.

To view this, run your CRA app and add this to the src/index.js file:

console.log('public url: ', process.env.PUBLIC_URL)

You'll see the URL already exists.

Read more in the CRA docs.

Relative to most people here I am new to java but since I haven't seen a similar suggestion I have another alternative to suggest. Im not sure if its a good practice or not, or even suggested before and I just didn't get it. I just like it since I think its self descriptive.

 /*Just to merge functions in a common name*/
 public class CustomFunction{ 
 public CustomFunction(){}
 }

 /*Actual functions*/
 public class Function1 extends CustomFunction{
 public Function1(){}
 public void execute(){...something here...}
 }

 public class Function2 extends CustomFunction{
 public Function2(){}
 public void execute(){...something here...}
 }

 .....
 /*in Main class*/
 CustomFunction functionpointer = null;

then depending on the application, assign

 functionpointer = new Function1();
 functionpointer = new Function2();

etc.

and call by

 functionpointer.execute();

Being aware of the transaction (autocommit, explicit and implicit) handling for your database can save you from having to restore data from a backup.

Transactions control data manipulation statement(s) to ensure they are atomic. Being "atomic" means the transaction either occurs, or it does not. The only way to signal the completion of the transaction to database is by using either a COMMIT or ROLLBACK statement (per ANSI-92, which sadly did not include syntax for creating/beginning a transaction so it is vendor specific). COMMIT applies the changes (if any) made within the transaction. ROLLBACK disregards whatever actions took place within the transaction - highly desirable when an UPDATE/DELETE statement does something unintended.

Typically individual DML (Insert, Update, Delete) statements are performed in an autocommit transaction - they are committed as soon as the statement successfully completes. Which means there's no opportunity to roll back the database to the state prior to the statement having been run in cases like yours. When something goes wrong, the only restoration option available is to reconstruct the data from a backup (providing one exists). In MySQL, autocommit is on by default for InnoDB - MyISAM doesn't support transactions. It can be disabled by using:

SET autocommit = 0

An explicit transaction is when statement(s) are wrapped within an explicitly defined transaction code block - for MySQL, that's START TRANSACTION. It also requires an explicitly made COMMIT or ROLLBACK statement at the end of the transaction. Nested transactions is beyond the scope of this topic.

Implicit transactions are slightly different from explicit ones. Implicit transactions do not require explicity defining a transaction. However, like explicit transactions they require a COMMIT or ROLLBACK statement to be supplied.

Conclusion

Explicit transactions are the most ideal solution - they require a statement, COMMIT or ROLLBACK, to finalize the transaction, and what is happening is clearly stated for others to read should there be a need. Implicit transactions are OK if working with the database interactively, but COMMIT statements should only be specified once results have been tested & thoroughly determined to be valid.

That means you should use:

SET autocommit = 0;

START TRANSACTION;
  UPDATE ...;

...and only use COMMIT; when the results are correct.

That said, UPDATE and DELETE statements typically only return the number of rows affected, not specific details. Convert such statements into SELECT statements & review the results to ensure correctness prior to attempting the UPDATE/DELETE statement.

Addendum

DDL (Data Definition Language) statements are automatically committed - they do not require a COMMIT statement. IE: Table, index, stored procedure, database, and view creation or alteration statements.

Short answer, no. Long answer, you can run Linux application if you install some software.

To avoid rooting your device, you can try the GnuRoot and XSDL combo to get a minimal chrooted environment, (Actually, it use proot to enable a rootless chrooted jail), or get the Debian Noroot application, which combine the former two application in a single virtual machine environment. Both can be fetch from Google Play.

However, there is a few drawbacks: first, the X11 Server bundled by XSDL and DNR is a compatibility layer wrapped around a Android port of SDL library and SurfaceFlinger. This means, hardware accelerated OpenGL graphics are not avaliable, and even the sound support requires some hacks. So, the author choose a simple Desktop Environment: XFCE4 suitable to low memmory and no 3D support. The second problem is the incompatibility from the DNR Virtual Machine of direct hardware acess, since it requires real root privileges. So you can't burn DVD, print using USB cables,... even the author's projects may promise a workaround in a future. Finally, this solution enables to install user-space programs like LibreOffice, Gimp, Samba,... not kernel-space modules.

Even with this limitations, the DNR is a very powerfull program.

or you can use java 8 lambda

test.removeIf(i -> i==2);

it will simply remove all object that meet the condition

Node.js as a background service in WINDOWS XP

• Kudos goes to Hacksparrow at: http://www.hacksparrow.com/install-node-js-and-npm-on-windows.html for tutorial installing Node.js + npm for windows.
• Kudos goes to Tatham Oddie at: http://blog.tatham.oddie.com.au/2011/03/16/node-js-on-windows/ for nnsm.exe implementation.

Installation:

1. Install WGET http://gnuwin32.sourceforge.net/packages/wget.htm via installer executable
2. Install GIT http://code.google.com/p/msysgit/downloads/list via installer executable
3. Install NSSM http://nssm.cc/download/?page=download via copying nnsm.exe into %windir%/system32 folder

4. Create c:\node\helloworld.js

   // http://howtonode.org/hello-node
   var http = require('http');
   var server = http.createServer(function (request, response) {
       response.writeHead(200, {"Content-Type": "text/plain"});
       response.end("Hello World\n");
   });
   server.listen(8000);
   console.log("Server running at http://127.0.0.1:8000/");
   

5. Open command console and type the following (setx only if Resource Kit is installed)

   C:\node> set path=%PATH%;%CD%
   C:\node> setx path "%PATH%"
   C:\node> set NODE_PATH="C:\Program Files\nodejs\node_modules"
   C:\node> git config --system http.sslcainfo /bin/curl-ca-bundle.crt    
   C:\node> git clone --recursive git://github.com/isaacs/npm.git    
   C:\node> cd npm    
   C:\node\npm> node cli.js install npm -gf   
   C:\node> cd ..    
   C:\node> nssm.exe install node-helloworld "C:\Program Files\nodejs\node.exe" c:\node\helloworld.js    
   C:\node> net start node-helloworld
   

6. A nifty batch goodie is to create c:\node\ServiceMe.cmd

   @echo off
   nssm.exe install node-%~n1 "C:\Program Files\nodejs\node.exe" %~s1
   net start node-%~n1
   pause
   

Service Management:

• The services themselves are now accessible via Start-> Run-> services.msc or via Start->Run-> MSCONFIG-> Services (and check 'Hide All Microsoft Services').
• The script will prefix every node made via the batch script with 'node-'.
• Likewise they can be found in the registry: "HKLM\SYSTEM\CurrentControlSet\Services\node-xxxx"

So, I had this code:

<div class="dropdown-select-wrapper" *ngIf="contentData">
    <button mat-stroked-button [disableRipple]="true" class="mat-button" (click)="openSelect()" [ngClass]="{'only-icon': !contentData?.buttonText?.length}">
      <i *ngIf="contentData.iconClassInfo" class="dropdown-icon {{contentData.iconClassInfo.name}}"></i>
      <span class="button-text" *ngIf="contentData.buttonText">{{contentData.buttonText}}</span>
    </button>
    <mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();">
      <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
        {{option[contentData.optionsStructure.keyName]}}
      </mat-option>
    </mat-select>
  </div>

Here I was using standalone formControl, and I was getting the error we are talking about, which made no sense for me, since I wasn't working with formgroups or formarrays... it only disappeared when I added the *ngIf to the select it self, so is not being used before it actually exists. That's what solved the issue in my case.

<mat-select class="small-dropdown-select" [formControl]="theFormControl" #buttonSelect (selectionChange)="onSelect(buttonSelect.selected)" (click)="$event.stopPropagation();" *ngIf="theFormControl">
          <mat-option *ngFor="let option of options" [ngClass]="{'selected-option': buttonSelect.selected?.value === option[contentData.optionsStructure.valName]}" [disabled]="buttonSelect.selected?.value === option[contentData.optionsStructure.valName] && contentData.optionSelectedWillDisable" [value]="option[contentData.optionsStructure.valName]">
            {{option[contentData.optionsStructure.keyName]}}
          </mat-option>
        </mat-select>

Code:

if(preg_match('/[^a-z_\-0-9]/i', $string))
{
  echo "not valid string";
}

Explanation:

• [] => character class definition
• ^ => negate the class
• a-z => chars from 'a' to 'z'
• _ => underscore
• - => hyphen '-' (You need to escape it)
• 0-9 => numbers (from zero to nine)

The 'i' modifier at the end of the regex is for 'case-insensitive' if you don't put that you will need to add the upper case characters in the code before by doing A-Z

here is the swift version of @jhibberd

    let cell:MsgTableViewCell! = self.tableView.dequeueReusableCellWithIdentifier("MsgTableViewCell", forIndexPath: indexPath) as? MsgTableViewCell
    cell.msgText.text = self.items[indexPath.row]
    var fixedWidth:CGFloat = cell.msgText.frame.size.width
    var size:CGSize = CGSize(width: fixedWidth,height: CGFloat.max)
    var newSize:CGSize = cell.msgText.sizeThatFits(size)
    var newFrame:CGRect = cell.msgText.frame;
    newFrame.size = CGSizeMake(CGFloat(fmaxf(Float(newSize.width), Float(fixedWidth))), newSize.height);
    cell.msgText.frame = newFrame
    cell.msgText.frame.size = newSize        
    return cell

Another way to do it, using axes.get_xlim():

import matplotlib.pyplot as plt
import numpy as np

def scatter_plot_with_correlation_line(x, y, graph_filepath):
    '''
    http://stackoverflow.com/a/34571821/395857
    x does not have to be ordered.
    '''
    # Create scatter plot
    plt.scatter(x, y)

    # Add correlation line
    axes = plt.gca()
    m, b = np.polyfit(x, y, 1)
    X_plot = np.linspace(axes.get_xlim()[0],axes.get_xlim()[1],100)
    plt.plot(X_plot, m*X_plot + b, '-')

    # Save figure
    plt.savefig(graph_filepath, dpi=300, format='png', bbox_inches='tight')

def main():
    # Data
    x = np.random.rand(100)
    y = x + np.random.rand(100)*0.1

    # Plot
    scatter_plot_with_correlation_line(x, y, 'scatter_plot.png')

if __name__ == "__main__":
    main()
    #cProfile.run('main()') # if you want to do some profiling

I would use your suggested code, but with a slight simplification:

KeyGenerator keyGen = KeyGenerator.getInstance("AES");
keyGen.init(256); // for example
SecretKey secretKey = keyGen.generateKey();

Let the provider select how it plans to obtain randomness - don't define something that may not be as good as what the provider has already selected.

This code example assumes (as Maarten points out below) that you've configured your java.security file to include your preferred provider at the top of the list. If you want to manually specify the provider, just call KeyGenerator.getInstance("AES", "providerName");.

For a truly secure key, you need to be using a hardware security module (HSM) to generate and protect the key. HSM manufacturers will typically supply a JCE provider that will do all the key generation for you, using the code above.

As the best anwser have writed using XMLHttpResponse except window.open, and I make the abstracts-anwser as a instance.

The main Js file is download.js Download-JS

 // var download_url = window.BASE_URL+ "/waf/p1/download_rules";
    var download_url = window.BASE_URL+ "/waf/p1/download_logs_by_dt";
    function download33() {
        var sender_data = {"start_time":"2018-10-9", "end_time":"2018-10-17"};
        var x=new XMLHttpRequest();
        x.open("POST", download_url, true);
        x.setRequestHeader("Content-type","application/json");
//        x.setRequestHeader("Access-Control-Allow-Origin", "*");
        x.setRequestHeader("Authorization", "JWT " + localStorage.token );
        x.responseType = 'blob';
        x.onload=function(e){download(x.response, "test211.zip", "application/zip" ); }
        x.send( JSON.stringify(sender_data) ); // post-data
    }

Your guess is right: the code is trying to evaluate x**3+2*x-4 immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:

import numpy as np  
import matplotlib.pyplot as plt  

def graph(formula, x_range):  
    x = np.array(x_range)  
    y = formula(x)  # <- note now we're calling the function 'formula' with x
    plt.plot(x, y)  
    plt.show()  

def my_formula(x):
    return x**3+2*x-4

graph(my_formula, range(-10, 11))

If you wanted to do it all in one line, you could use what's called a lambda function, which is just a short function without a name where you don't use def or return:

graph(lambda x: x**3+2*x-4, range(-10, 11))

And instead of range, you can look at np.arange (which allows for non-integer increments), and np.linspace, which allows you to specify the start, stop, and the number of points to use.

char **orderIds;

orderIds = malloc(variableNumberOfElements * sizeof(char*));

for(int i = 0; i < variableNumberOfElements; i++) {
  orderIds[i] = malloc((ID_LEN + 1) * sizeof(char));
  strcpy(orderIds[i], your_string[i]);
}

Best choice is using

AppDomain.CurrentDomain.BaseDirectory

because it's in the system namespace and there is no dependency to system.web

this way your code will be more portable

One simple way is

Comparator<Dog> ageAscendingComp = ...;
Comparator<Dog> ageDescendingComp = Collections.reverseOrder(ageAscendingComp);
// then call the sort method

On a side note, Dog should really not implement Comparator. It means you have to do strange things like

Collections.sort(myList, new Dog("Rex", 4));
// ^-- why is a new dog being made? What are we even sorting by?!
Collections.sort(myList, myList.get(0));
// ^-- or perhaps more confusingly

Rather you should make Compartors as separate classes.

eg.

public class DogAgeComparator implments Comparator<Dog> {
    public int compareTo(Dog d1, Dog d2) {
        return d1.getAge() - d2.getAge();
    }
}

This has the added benefit that you can use the name of the class to say how the Comparator will sort the list. eg.

Collections.sort(someDogs, new DogNameComparator());
// now in name ascending order

Collections.sort(someDogs, Collections.reverseOrder(new DogAgeComparator()));
// now in age descending order

You should also not not have Dog implement Comparable. The Comparable interface is used to denote that there is some inherent and natural way to order these objects (such as for numbers and strings). Now this is not the case for Dog objects as sometimes you may wish to sort by age and sometimes you may wish to sort by name.

Take care to provide only 1 setter and getter for any attribute. The best way to approach is to write down the definition of all the attributes then use eclipse generate setter and getter utility rather than doing it manually. The option comes on right click-> source -> Generate Getter and Setter.

Your regular expression [a-z] doesn't match dkoe since it only matches Strings of lenght 1. Use something like [a-z]+.

I used Custom Action separately coded in C++ DLL and used the DLL to call appropriate function on Uninstalling using this syntax :

<CustomAction Id="Uninstall" BinaryKey="Dll_Name" 
              DllEntry="Function_Name" Execute="deferred" />

Using the above code block, I was able to run any function defined in C++ DLL on uninstall. FYI, my uninstall function had code regarding Clearing current user data and registry entries.

Since arrays must be indexed with integers, the maximum length of an array is Integer.MAX_INT (2³¹-1, or 2 147 483 647). This is assuming you have enough memory to hold an array of that size, of course.

Use the end() function.

$array = [1,2,3,4,5];
$last = end($array); // 5

Using HTTP Request verb such as GET, POST, DELETE, PUT etc... enables you to build RESTful web applications. Read about it here: http://en.wikipedia.org/wiki/Representational_state_transfer

The easiest way to see benefits from this is to look at this example. Every MVC framework has a Router/Dispatcher that maps URL-s to actionControllers. So URL like this: /blog/article/1 would invoke blogController::articleAction($id); Now this Router is only aware of the URL or /blog/article/1/

But if that Router would be aware of whole HTTP Request object instead of just URL, he could have access HTTP Request verb (GET, POST, PUT, DELETE...), and many other useful stuff about current HTTP Request.

That would enable you to configure application so it can accept the same URL and map it to different actionControllers depending on the HTTP Request verb.

For example:

if you want to retrive article 1 you can do this:

GET /blog/article/1 HTTP/1.1

but if you want to delete article 1 you will do this:

DELETE /blog/article/1 HTTP/1.1

Notice that both HTTP Requests have the same URI, /blog/article/1, the only difference is the HTTP Request verb. And based on that verb your router can call different actionController. This enables you to build neat URL-s.

Read this two articles, they might help you:

Symfony 2 - HTTP Fundamentals

Symfony 2 - Routing

These articles are about Symfony 2 framework, but they can help you to figure out how does HTTP Requests and Responses work.

Hope this helps!

I follow Wordpress's example on this one. I go and define a root path, normally the document root, and then go define a bunch of other path's along with that (one for each of my class dirs. IE: database, users, html, etc). Often I will define the root path manually instead of relying on a server variable.

Example

if($_SERVER['SERVERNAME'] == "localhost")
{
    define("ABS_PATH", "/path/to/upper/most/directory"); // Manual
}
else
{
    define("ABS_PATH, dirname(__FILE__));
    // This defines the path as the directory of the containing file, normally a config.php
}

// define other paths...

include(ABS_PATH."/mystuff.php");

From Python 3.9, the zoneinfo module can be used for getting timezones rather than using a third party library.

To get the current time in a particular timezone:

from datetime import datetime
from zoneinfo import ZoneInfo

datetime.now(tz=ZoneInfo("Europe/Amsterdam"))

It's possible to prevent webpage scaling in safari on iOS 10, but it's going to involve more work on your part. I guess the argument is that a degree of difficulty should stop cargo-cult devs from dropping "user-scalable=no" into every viewport tag and making things needlessly difficult for vision-impaired users.

Still, I would like to see Apple change their implementation so that there is a simple (meta-tag) way to disable double-tap-to-zoom. Most of the difficulties relate to that interaction.

You can stop pinch-to-zoom with something like this:

document.addEventListener('touchmove', function (event) {
  if (event.scale !== 1) { event.preventDefault(); }
}, false);

Note that if any deeper targets call stopPropagation on the event, the event will not reach the document and the scaling behavior will not be prevented by this listener.

Disabling double-tap-to-zoom is similar. You disable any tap on the document occurring within 300 milliseconds of the prior tap:

var lastTouchEnd = 0;
document.addEventListener('touchend', function (event) {
  var now = (new Date()).getTime();
  if (now - lastTouchEnd <= 300) {
    event.preventDefault();
  }
  lastTouchEnd = now;
}, false);

If you don't set up your form elements right, focusing on an input will auto-zoom, and since you have mostly disabled manual zoom, it will now be almost impossible to unzoom. Make sure the input font size is >= 16px.

If you're trying to solve this in a WKWebView in a native app, the solution given above is viable, but this is a better solution: https://stackoverflow.com/a/31943976/661418. And as mentioned in other answers, in iOS 10 beta 6, Apple has now provided a flag to honor the meta tag.

Update May 2017: I replaced the old 'check touches length on touchstart' method of disabling pinch-zoom with a simpler 'check event.scale on touchmove' approach. Should be more reliable for everyone.

A snippet out of the MSDN:

'The following code sample shows how to create a DateTimePicker that enables users to choose a time only.'

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Time;
timePicker.ShowUpDown = true;

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

No you are not required to close anything BUT the connection. Per JDBC specs closing any higher object will automatically close lower objects. Closing Connection will close any Statements that connection has created. Closing any Statement will close all ResultSets that were created by that Statement. Doesn't matter if Connection is poolable or not. Even poolable connection has to clean before returning to the pool.

Of course you might have long nested loops on the Connection creating lots of statements, then closing them is appropriate. I almost never close ResultSet though, seems excessive when closing Statement or Connection WILL close them.

I would recommend you look at getting the anaconda package, it will install and configure Sklearn and its dependencies.

With the Hub command-line wrapper you can link it to git and then you can do git pull-request

From the man page of hub:

   git pull-request [-f] [TITLE|-i ISSUE|ISSUE-URL] [-b BASE] [-h HEAD]
          Opens a pull request on GitHub for the project that the "origin" remote points to. The default head of the pull request is the current branch. Both base and head of the pull request can be explicitly given in one  of  the  following  formats:  "branch",  "owner:branch",
          "owner/repo:branch". This command will abort operation if it detects that the current topic branch has local commits that are not yet pushed to its upstream branch on the remote. To skip this check, use -f.

          If TITLE is omitted, a text editor will open in which title and body of the pull request can be entered in the same manner as git commit message.

          If instead of normal TITLE an issue number is given with -i, the pull request will be attached to an existing GitHub issue. Alternatively, instead of title you can paste a full URL to an issue on GitHub.

Adding another answer to this question because I needed precisely what @derek was asking for and I'd already gotten a bit further before seeing the answers here. Specifically, I needed CSS that could also account for the case with exactly two list items, where the comma is NOT desired. As an example, some authorship bylines I wanted to produce would look like the following:

One author: By Adam Smith.

Two authors: By Adam Smith and Jane Doe.

Three authors: By Adam Smith, Jane Doe, and Frank Underwood.

The solutions already given here work for one author and for 3 or more authors, but neglect to account for the two author case—where the "Oxford Comma" style (also known as "Harvard Comma" style in some parts) doesn't apply - ie, there should be no comma before the conjunction.

After an afternoon of tinkering, I had come up with the following:

<html>
 <head>
  <style type="text/css">
    .byline-list {
      list-style: none;
      padding: 0;
      margin: 0;
    }
    .byline-list > li {
      display: inline;
      padding: 0;
      margin: 0;
    }
    .byline-list > li::before {
      content: ", ";
    }
    .byline-list > li:last-child::before {
      content: ", and ";
    }
    .byline-list > li:first-child + li:last-child::before {
      content: " and ";
    }
    .byline-list > li:first-child::before {
      content: "By ";
    }
    .byline-list > li:last-child::after {
      content: ".";
    }
  </style>
 </head>
 <body>
  <ul class="byline-list">
   <li>Adam Smith</li>
  </ul>
  <ul class="byline-list">
   <li>Adam Smith</li><li>Jane Doe</li>
  </ul>
  <ul class="byline-list">
   <li>Adam Smith</li><li>Jane Doe</li><li>Frank Underwood</li>
  </ul>
 </body>
</html>

It displays the bylines as I've got them above.

In the end, I also had to get rid of any whitespace between li elements, in order to get around an annoyance: the inline-block property would otherwise leave a space before each comma. There's probably an alternative decent hack for it but that isn't the subject of this question so I'll leave that for someone else to answer.

Fiddle here: http://jsfiddle.net/5REP2/

I think your cron is not correct. According to what you described, you may need to change cron schedule to

*/5 * * * *

What you put in your schedule now mean it will poll the SCM at 5 past of every hour.

If you're trying to stop someone from updating the checkbox so it appears disabled then just use JQuery

$('input[type=checkbox]').click(false);

You can then style the checkbox.

DEMO: Resizing images with JS and HTML Canvas Demo fiddler.

You may find 3 different methods to do this resize, that will help you understand how the code is working and why.

https://jsfiddle.net/1b68eLdr/93089/

Full code of both demo, and TypeScript method that you may want to use in your code, can be found in the GitHub project.

https://github.com/eyalc4/ts-image-resizer

This is the final code:

export class ImageTools {
base64ResizedImage: string = null;

constructor() {
}

ResizeImage(base64image: string, width: number = 1080, height: number = 1080) {
    let img = new Image();
    img.src = base64image;

    img.onload = () => {

        // Check if the image require resize at all
        if(img.height <= height && img.width <= width) {
            this.base64ResizedImage = base64image;

            // TODO: Call method to do something with the resize image
        }
        else {
            // Make sure the width and height preserve the original aspect ratio and adjust if needed
            if(img.height > img.width) {
                width = Math.floor(height * (img.width / img.height));
            }
            else {
                height = Math.floor(width * (img.height / img.width));
            }

            let resizingCanvas: HTMLCanvasElement = document.createElement('canvas');
            let resizingCanvasContext = resizingCanvas.getContext("2d");

            // Start with original image size
            resizingCanvas.width = img.width;
            resizingCanvas.height = img.height;


            // Draw the original image on the (temp) resizing canvas
            resizingCanvasContext.drawImage(img, 0, 0, resizingCanvas.width, resizingCanvas.height);

            let curImageDimensions = {
                width: Math.floor(img.width),
                height: Math.floor(img.height)
            };

            let halfImageDimensions = {
                width: null,
                height: null
            };

            // Quickly reduce the size by 50% each time in few iterations until the size is less then
            // 2x time the target size - the motivation for it, is to reduce the aliasing that would have been
            // created with direct reduction of very big image to small image
            while (curImageDimensions.width * 0.5 > width) {
                // Reduce the resizing canvas by half and refresh the image
                halfImageDimensions.width = Math.floor(curImageDimensions.width * 0.5);
                halfImageDimensions.height = Math.floor(curImageDimensions.height * 0.5);

                resizingCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                    0, 0, halfImageDimensions.width, halfImageDimensions.height);

                curImageDimensions.width = halfImageDimensions.width;
                curImageDimensions.height = halfImageDimensions.height;
            }

            // Now do final resize for the resizingCanvas to meet the dimension requirments
            // directly to the output canvas, that will output the final image
            let outputCanvas: HTMLCanvasElement = document.createElement('canvas');
            let outputCanvasContext = outputCanvas.getContext("2d");

            outputCanvas.width = width;
            outputCanvas.height = height;

            outputCanvasContext.drawImage(resizingCanvas, 0, 0, curImageDimensions.width, curImageDimensions.height,
                0, 0, width, height);

            // output the canvas pixels as an image. params: format, quality
            this.base64ResizedImage = outputCanvas.toDataURL('image/jpeg', 0.85);

            // TODO: Call method to do something with the resize image
        }
    };
}}

Decision tree:

1. Frameworks like Qt and SWT need native DLLs. So you have to ask yourself: Are all necessary platforms supported? Can you package the native DLLs with your app?

   See here, how to do this for SWT.

   If you have a choice here, you should prefer Qt over SWT. Qt has been developed by people who understand UI and the desktop while SWT has been developed out of necessity to make Eclipse faster. It's more a performance patch for Java 1.4 than a UI framework. Without JFace, you're missing many major UI components or very important features of UI components (like filtering on tables).

   If SWT is missing a feature that you need, the framework is somewhat hostile to extending it. For example, you can't extend any class in it (the classes aren't final, they just throw exceptions when the package of this.getClass() isn't org.eclipse.swt and you can't add new classes in that package because it's signed).

2. If you need a native, pure Java solution, that leaves you with the rest. Let's start with AWT, Swing, SwingX - the Swing way.

   AWT is outdated. Swing is outdated (maybe less so but not much work has been done on Swing for the past 10 years). You could argue that Swing was good to begin with but we all know that code rots. And that's especially true for UIs today.

   That leaves you with SwingX. After a longer period of slow progress, development has picked up again. The major drawback with Swing is that it hangs on to some old ideas which very kind of bleeding edge 15 years ago but which feel "clumsy" today. For example, the table views do support filtering and sorting but you still have to configure this. You'll have to write a lot of boiler plate code just to get a decent UI that feels modern.

   Another weak area is theming. As of today, there are a lot of themes around. See here for a top 10. But some are slow, some are buggy, some are incomplete. I hate it when I write a UI and users complain that something doesn't work for them because they selected an odd theme.

3. JGoodies is another layer on top of Swing, like SwingX. It tries to make Swing more pleasant to use. The web site looks great. Let's have a look at the tutorial ... hm ... still searching ... hang on. It seems that there is no documentation on the web site at all. Google to the rescue. Nope, no useful tutorials at all.

   I'm not feeling confident with a UI framework that tries so hard to hide the documentation from potential new fans. That doesn't mean JGoodies is bad; I just couldn't find anything good to say about it but that it looks nice.

4. JavaFX. Great, stylish. Support is there but I feel it's more of a shiny toy than a serious UI framework. This feeling roots in the lack of complex UI components like tree tables. There is a webkit-based component to display HTML.

   When it was introduced, my first thought was "five years too late." If your aim is a nice app for phones or web sites, good. If your aim is professional desktop application, make sure it delivers what you need.

5. Pivot. First time I heard about it. It's basically a new UI framework based on Java2D. So I gave it a try yesterday. No Swing, just tiny bit of AWT (new Font(...)).

   My first impression was a nice one. There is an extensive documentation that helps you getting started. Most of the examples come with live demos (Note: You must have Java enabled in your web browser; this is a security risk) in the web page, so you can see the code and the resulting application side by side.

   In my experience, more effort goes into code than into documentation. By looking at the Pivot docs, a lot of effort must have went into the code. Note that there is currently a bug which prevents some of the examples to work (PIVOT-858) in your browser.

   My second impression of Pivot is that it's easy to use. When I ran into a problem, I could usually solve it quickly by looking at an example. I'm missing a reference of all the styles which each component supports, though.

   As with JavaFX, it's missing some higher level components like a tree table component (PIVOT-306). I didn't try lazy loading with the table view. My impression is that if the underlying model uses lazy loading, then that's enough.

   Promising. If you can, give it a try.

Try

LimitRequestBody 1024000000

You can just use relative layout inside toolbar view group in your xml file and adjust the positions of widgets as you require them for your use case.No need to create custom layout & inflate it and attach to toolbar. Once done in your java code use setContentInsetsAbsolute(0,0) with your toolbar object before setting it as support action bar in your layout.

On OSX use fn instead of shift.

You may want to take a look at Pyschools, the website has quite a lot of practice questions on Python Programming.

If you would like to apply all of the common boolean masks as well as a general purpose mask you can chuck the following in a file and then simply assign them all as follows:

pd.DataFrame = apply_masks()

Usage:

A = pd.DataFrame(np.random.randn(4, 4), columns=["A", "B", "C", "D"])
A.le_mask("A", 0.7).ge_mask("B", 0.2)... (May be repeated as necessary

It's a little bit hacky but it can make things a little bit cleaner if you're continuously chopping and changing datasets according to filters. There's also a general purpose filter adapted from Daniel Velkov above in the gen_mask function which you can use with lambda functions or otherwise if desired.

File to be saved (I use masks.py):

import pandas as pd

def eq_mask(df, key, value):
    return df[df[key] == value]

def ge_mask(df, key, value):
    return df[df[key] >= value]

def gt_mask(df, key, value):
    return df[df[key] > value]

def le_mask(df, key, value):
    return df[df[key] <= value]

def lt_mask(df, key, value):
    return df[df[key] < value]

def ne_mask(df, key, value):
    return df[df[key] != value]

def gen_mask(df, f):
    return df[f(df)]

def apply_masks():

    pd.DataFrame.eq_mask = eq_mask
    pd.DataFrame.ge_mask = ge_mask
    pd.DataFrame.gt_mask = gt_mask
    pd.DataFrame.le_mask = le_mask
    pd.DataFrame.lt_mask = lt_mask
    pd.DataFrame.ne_mask = ne_mask
    pd.DataFrame.gen_mask = gen_mask

    return pd.DataFrame

if __name__ == '__main__':
    pass

Good answers above- if you're looking for something reusable here is the code. Note that you might want to check the decimal places value, and this may overflow.

public static decimal TruncateToDecimalPlace(this decimal numberToTruncate, int decimalPlaces)
{
    decimal power = (decimal)(Math.Pow(10.0, (double)decimalPlaces));

    return Math.Truncate((power * numberToTruncate)) / power;
}

Two entries in an array can't share a key, you'll need to change the key for the duplicate

have you installed a user db2inst2, i think, i remember, that db2inst1 is very administrative

Whenever I attempt to remove the constraints that the system had to break, my constraints are no longer enough to satisfy the IB (ie "missing constraints" shows in the IB, which means they're incomplete and won't be used). I actually got around this by setting the constraint it wants to break to low priority, which (and this is an assumption) allows the system to break the constraint gracefully. It's probably not the best solution, but it solved my problem and the resulting constraints worked perfectly.

I got into a similar situation (svn: 'papers' is not a working copy directory) a different way, so I thought I'd post my battle story (simplified):

$ svn add papers
svn: Can't create directory 'papers/.svn': Permission denied

Oops! fix permissions... then:

$ svn add papers
svn: warning: 'papers' is already under version control
$ svn st
~     papers
$ svn cleanup
svn: 'papers' is not a working copy directory

And even moving papers out of the way and running svn up (which worked for the OP) didn't fix it. Here's what I did:

$ mv papers papers_
$ svn cleanup
$ svn revert papers
Reverted 'papers'
$ mv papers_/ papers
$ svn add papers

That worked.

I would like to offer a generalized example for a very similar use case:

Use Case: I have a csv consisting of:

First|Third|Fifth
data|data|data
data|data|data
...billion more lines

I need to perform some transformations and the final csv needs to look like

First|Second|Third|Fourth|Fifth
data|null|data|null|data
data|null|data|null|data
...billion more lines

I need to do this because this is the schema defined by some model and I need for my final data to be interoperable with SQL Bulk Inserts and such things.

so:

1) I read the original csv using spark.read and call it "df".

2) I do something to the data.

3) I add the null columns using this script:

outcols = []
for column in MY_COLUMN_LIST:
    if column in df.columns:
        outcols.append(column)
    else:
        outcols.append(lit(None).cast(StringType()).alias('{0}'.format(column)))

df = df.select(outcols)

In this way, you can structure your schema after loading a csv (would also work for reordering columns if you have to do this for many tables).

Here's my code (not optimized but a full working example):

<head>
<style>
#divtoshow {position:absolute;display:none;color:white;background-color:black}
#onme {width:150px;height:80px;background-color:yellow;cursor:pointer}
</style>
<script type="text/javascript">
var divName = 'divtoshow'; // div that is to follow the mouse (must be position:absolute)
var offX = 15;          // X offset from mouse position
var offY = 15;          // Y offset from mouse position

function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ?  document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;}
function mouseY(evt) {if (!evt) evt = window.event; if (evt.pageY) return evt.pageY; else if (evt.clientY)return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); else return 0;}

function follow(evt) {
    var obj = document.getElementById(divName).style;
    obj.left = (parseInt(mouseX(evt))+offX) + 'px';
    obj.top = (parseInt(mouseY(evt))+offY) + 'px'; 
    }
document.onmousemove = follow;
</script>
</head>
<body>
<div id="divtoshow">test</div>
<br><br>
<div id='onme' onMouseover='document.getElementById(divName).style.display="block"' onMouseout='document.getElementById(divName).style.display="none"'>Mouse over this</div>
</body>

My answer is a mod of some prior answers from @JoeMills and @user.

1. Get a cURL command to log into server:

   • Load login page for website and open Network pane of Developer Tools
     • In firefox, right click page, choose 'Inspect Element (Q)' and click on Network tab
   • Go to login form, enter username, password and log in
   • After you have logged in, go back to Network pane and scroll to the top to find the POST entry. Right click and choose Copy -> Copy as CURL
   • Paste this to a text editor and try this in command prompt to see if it works
     • Its possible that some sites have hardening that will block this type of login spoofing that would require more steps below to bypass.

2. Modify cURL command to be able to save session cookie after login

   • Remove the entry -H 'Cookie: <somestuff>'
   • Add after curl at beginning -c login_cookie.txt
   • Try running this updated curl command and you should get a new file 'login_cookie.txt' in the same folder

3. Call a new web page using this new cookie that requires you to be logged in

   • curl -b login_cookie.txt <url_that_requires_log_in>

I have tried this on Ubuntu 20.04 and it works like a charm.

try this one:

    <td style="min-width:50px">one</td>
    <td style="min-width:100px">two</td>
</tr>
</table>

Here's an updated link.

There are updated now and then, just keep checking for the latest version.

Gitk sometime painful for me to read.

Motivate me to write GitVersionTree.

your string should be in the following format:

$str = '{"action": "create","record": {"type": "n$product","fields": {"n$name": "Bread","n$price": 2.11},"namespaces": { "my.demo": "n" }}}';
$array = json_decode($str, true);

echo "<pre>";
print_r($array);

Output:

Array
 (
    [action] => create
    [record] => Array
        (
            [type] => n$product
            [fields] => Array
                (
                    [n$name] => Bread
                    [n$price] => 2.11
                )

            [namespaces] => Array
                (
                    [my.demo] => n
                )

        )

)

Clean and Simple:

$('#signup').submit(function(event) {

      alert(this.action);
});

as @rampion mentioned, if you are in clang gcc, the warnings are by name, not number, and you'll need to do:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused-variable"
// ..your code..
#pragma clang diagnostic pop

this info comes from here

Simply add this to your pom.xml:

I'm adding this for posterity; There's an easier way that doesn't involve writing more JS. Using the amazing firebug addon for firefox,

1. Right click on the element and select 'Inspect element with Firebug'
2. In the sidebar panels (shown in the screenshot), navigate to the events tab using the tiny > arrow
3. The events tab shows the events and corresponding functions for each event
4. The text next to it shows the function location

With CSS:

selector { cursor: none; }

An example:

<div class="nocursor">_x000D_
   Some stuff_x000D_
</div>_x000D_
<style type="text/css">_x000D_
    .nocursor { cursor:none; }_x000D_
</style>

To set this on an element in Javascript, you can use the style property:

<div id="nocursor"><!-- some stuff --></div>
<script type="text/javascript">
    document.getElementById('nocursor').style.cursor = 'none';
</script>

If you want to set this on the whole body:

<script type="text/javascript">
    document.body.style.cursor = 'none';
</script>

Make sure you really want to hide the cursor, though. It can really annoy people.

You can use like this

$(".jsgrid-cell").each(function(i,v){
    var txt=$(v).text();
    if(txt.length>100){
        var shortText=txt.substring(0, 100)+
        "<span onclick='$(this).hide();$(this).next().toggle();'>"+
            "..."+
        "</span>"+
        "<span  style='display:none'>"+
            txt.substring(100, txt.length)+
        "</span>";

        $(v).html(shortText );
    }
});

This is slightly modified version of Mark Ransom's answer that works if ch could be more than one character in length.

def find(term, ch):
    """Find all places with ch in str
    """
    for i in range(len(term)):
        if term[i:i + len(ch)] == ch:
            yield i

You can do it with an UPDATE statement setting the value with a REPLACE

UPDATE
    Table
SET
    Column = Replace(Column, 'find value', 'replacement value')
WHERE
    xxx

You will want to be extremely careful when doing this! I highly recommend doing a backup first.

Declare @phoneNumber int

select @phoneNumber=Isnull('08041159620',0);

Give error :

The conversion of the varchar value '8041159620' overflowed an int column.: select cast('8041159620' as int)

AS

Integer is defined as :

Integer (whole number) data from -2^31 (-2,147,483,648) through 2^31 - 1 (2,147,483,647). Storage size is 4 bytes. The SQL-92 synonym for int is integer.

Solution

Declare @phoneNumber bigint

Reference

As I've said as "Thrift vs Protocol buffers" topic :

Referring to Thrift vs Protobuf vs JSON comparison :

• Thrift supports out of the box AS3, C++, C#, D, Delphi, Go, Graphviz, Haxe, Haskell, Java, Javascript, Node.js, OCaml, Smalltalk, Typescript, Perl, PHP, Python, Ruby, ...
• C++, Python, Java - in-box support in Protobuf
• Protobuf support for other languages (including Lua, Matlab, Ruby, Perl, R, Php, OCaml, Mercury, Erlang, Go, D, Lisp) is available as Third Party Addons (btw. Here is SWI-Prolog support).
• Protobuf has much better documentation and plenty of examples.
• Thrift comes with a good tutorial
• Protobuf objects are smaller
• Protobuf is faster when using "optimize_for = SPEED" configuration
• Thrift has integrated RPC implementation, while for Protobuf RPC solutions are separated, but available (like Zeroc ICE ).
• Protobuf is released under BSD-style license
• Thrift is released under Apache 2 license

Additionally, there are plenty of interesting additional tools available for those solutions, which might decide. Here are examples for Protobuf: Protobuf-wireshark , protobufeditor.

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

Use the HorizontalAlignment and VerticalAlignment layout properties. They control how an element uses the space it has inside its parent when more room is available than it required by the element.

The width of a StackPanel, for example, will be as wide as the widest element it contains. So, all narrower elements have a bit of excess space. The alignment properties control what the child element does with the extra space.

The default value for both properties is Stretch, so the child element is stretched to fill all available space. Additional options include Left, Center and Right for HorizontalAlignment and Top, Center and Bottom for VerticalAlignment.

bash -c works well if the commands you are running are relatively simple. However, if you're trying to run a long series of commands full of control characters, it can get complex.

I successfully got around this by piping my commands into the process from the outside, i.e.

cat script.sh | docker run -i <image> /bin/bash

If are you working with numbers a lot, you might want to take a look at NumPy. It lets you perform all kinds of operation directly on numerical arrays. For example:

>>> import numpy
>>> array = numpy.array([49, 51, 53, 56])
>>> array - 13
array([36, 38, 40, 43])

The safest way is to put the files you want kept to yourself outside of the web root directory, like Damien suggested. This works because the web server follows local file system privileges, not its own privileges.

However, there are a lot of hosting companies that only give you access to the web root. To still prevent HTTP requests to the files, put them into a directory by themselves with a .htaccess file that blocks all communication. For example,

Order deny,allow
Deny from all

Your web server, and therefore your server side language, will still be able to read them because the directory's local permissions allow the web server to read and execute the files.

For many types (integer, double, DateTime etc), there is a static Parse method. You can invoke it using reflection:

MethodInfo m = typeof(T).GetMethod("Parse", new Type[] { typeof(string) } );

if (m != null)
{
    return m.Invoke(null, new object[] { base.Value });
}

I think that understanding why you can't change the referer header might help people reading this question.

From this page: https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name

From that link:

A forbidden header name is the name of any HTTP header that cannot be modified programmatically...

Modifying such headers is forbidden because the user agent retains full control over them.

Forbidden header names ... are one of the following names:

Anonymous functions are meant to be one-shot deal where you define a function on the fly so that it generates an output from you from an input that you are providing. Except that you did not provide the input. Instead, you wrote something on the second line ('SO'); - an independent statement that has nothing to do with the function. What did you expect? :)

I have just got an solution a little bit easier do get an list out of an JSON object. Hope this can help.

I got an JSON like this:

{"Accounts":"[{\"bank\":\"Itau\",\"account\":\"456\",\"agency\":\"0444\",\"digit\":\"5\"}]"}

And made some types like this

    public class FinancialData
{
    public string Accounts { get; set; } // this will store the JSON string
    public List<Accounts> AccountsList { get; set; } // this will be the actually list. 
}

    public class Accounts
{
    public string bank { get; set; }
    public string account { get; set; }
    public string agency { get; set; }
    public string digit { get; set; }

}

and the "magic" part

 Models.FinancialData financialData = (Models.FinancialData)JsonConvert.DeserializeObject(myJSON,typeof(Models.FinancialData));
        var accounts = JsonConvert.DeserializeObject(financialData.Accounts) as JArray;

        foreach (var account in  accounts)
        {
            if (financialData.AccountsList == null)
            {
                financialData.AccountsList = new List<Models.Accounts>();
            }

            financialData.AccountsList.Add(JsonConvert.DeserializeObject<Models.Accounts>(account.ToString()));
        }

First of all, I want to say a big screw you to React for designing an interface that doesn't let us access 'ref' on the instantiated child components, in whatever context, without having to use the 'forwardRef' "hack" (which technically only works on specific/single instances, and not dynamic collections). Thanks for making our lives harder with your proprietary hook crap and now forcing us to use functional components (which can't inherit base functionality without more hacks). Why did JavaScript add class support to begin with? Right...

With that said, here is how I solve the problem for dynamic components:

On the parent, dynamically create references to the child components, for example:

class Form extends Component {
    fieldRefs: [];

    componentWillMount = () => {
        this.fieldRefs = [];
        for(let f of this.props.children) {
            if (f && f.type.name == 'FormField') {
                f.ref = createRef();
                this.fieldRefs.push(f);
            }
        }
    }

    public getFields = () => {
        let data = {};

        for(let r of this.fieldRefs) {
            let f = r.ref.current;
            data[f.props.id] = f.field.current.value;
        }

        return data;
    }
}

The Child component (ie <FormField />) implements it's own 'field' ref, to be referred to from the parent:

class FormField extends Component {
    field = createRef();
    
    render() {
        return(
            <input ref={this.field} type={type} />
        );
    }
}

Then in your main page, "Parent Parent" component, you can get the field values from the reference with:

class Page extends Component {
    form = createRef();

    onSubmit = () => {
        let fields = this.form.current.getFields();
    }

    render() {
        return (
            <Form ref={this.form}>
                <FormField id="email" type="email" autoComplete="email" label="E-mail" />
                <FormField id="password" type="password" autoComplete="password" label="Password" />

                <div class="button" onClick={this.onSubmit}>Submit</div>
            </Form>
        );
    }
}

I implemented this because I wanted to encapsulate all generic form functionality from a main <Form /> component, and the only way to be able to have the main client/page component set and style its own inner components was to use child components (ie. <FormField /> items within the parent <Form />, which is inside some other <Page /> component).

So, while some might consider this a hack, it's just as hackey as React's attempts to block the actual 'ref' from any parent, which I think is a ridiculous design, however they want to rationalize it.

Also wtf SO. It's 2021 and we still don't have get proper code-editing tools in your editor. Ffs.

Use ViewChild with #localvariable as shown here,

<textarea  #someVar  id="tasknote"
                  name="tasknote"
                  [(ngModel)]="taskNote"
                  placeholder="{{ notePlaceholder }}"
                  style="background-color: pink"
                  (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} 

</textarea>

In component,

OLDEST Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

ngAfterViewInit()
{
   this.el.nativeElement.focus();
}

OLD Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer) {}
ngAfterViewInit() {
    this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}

NEW Way

Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed. Since Angular team will deprecate invokeElementMethod, above code no longer can be used.

BREAKING CHANGES

since 4.0 rc.1:

rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2

import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer2) {}

ngAfterViewInit() {
      console.log(this.rd); 
      this.el.nativeElement.focus();      //<<<=====same as oldest way
}

console.log(this.rd) will give you following methods and you can see now invokeElementMethod is not there. Attaching img as yet it is not documented.

NOTE: You can use following methods of Rendere2 with/without ViewChild variable to do so many things.
