If you would like to query all columns

List<Users> list_users = new List<Users>();
MySqlConnection cn = new MySqlConnection("connection");
MySqlCommand cm = new MySqlCommand("select * from users",cn);
try
{
    cn.Open();
    MySqlDataReader dr = cm.ExecuteReader();
    while (dr.Read())
    {
        list_users.Add(new Users(dr));
    }
}
catch { /* error */ }
finally { cn.Close(); }

The User's constructor would do all the "dr.GetString(i)"

FuzzyFinder has been mentioned, however I love the textmate like behaviour of the FuzzyFinderTextmate plugin which extends the behaviour to include all subdirs.

Make sure you are using version 2.16 of fuzzyfinder.vim - The higher versions break the plugin.

you can set android theme of the checkbox to get the color you want in your styles.xml add :

<style name="checkBoxStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">CHECKEDHIGHLIGHTCOLOR</item>
    <item name="android:textColorSecondary">UNCHECKEDCOLOR</item>
</style>

then in your layout file :

<CheckBox
     android:theme="@style/checkBoxStyle"
     android:id="@+id/chooseItemCheckBox"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"/>

unlike using android:buttonTint="@color/CHECK_COLOR" this method works under Api 23

Downloading java dependencies is possible, if you actually really need to download them into a folder.

Example:

apply plugin: 'java'

dependencies {
  runtime group: 'com.netflix.exhibitor', name: 'exhibitor-standalone', version: '1.5.2'
  runtime group: 'org.apache.zookeeper',  name: 'zookeeper', version: '3.4.6'
}

repositories { mavenCentral() }

task getDeps(type: Copy) {
  from sourceSets.main.runtimeClasspath
  into 'runtime/'
}

Download the dependencies (and their dependencies) into the folder runtime when you execute gradle getDeps.

If I understand correctly, you have a vector containing variable names and would like loop through each name and sort your data frame by them. If so, this example should illustrate a solution for you. The primary issue in yours (the full example isn't complete so I"m not sure what else you may be missing) is that it should be order(Q1_R1000[,parameter[X]]) instead of order(Q1_R1000$parameter[X]), since parameter is an external object that contains a variable name opposed to a direct column of your data frame (which when the $ would be appropriate).

set.seed(1)
dat <- data.frame(var1=round(rnorm(10)),
                   var2=round(rnorm(10)),
                   var3=round(rnorm(10)))
param <- paste0("var",1:3)
dat
#   var1 var2 var3
#1    -1    2    1
#2     0    0    1
#3    -1   -1    0
#4     2   -2   -2
#5     0    1    1
#6    -1    0    0
#7     0    0    0
#8     1    1   -1
#9     1    1    0
#10    0    1    0

for(p in rev(param)){
   dat <- dat[order(dat[,p]),]
 }
dat
#   var1 var2 var3
#3    -1   -1    0
#6    -1    0    0
#1    -1    2    1
#7     0    0    0
#2     0    0    1
#10    0    1    0
#5     0    1    1
#8     1    1   -1
#9     1    1    0
#4     2   -2   -2

Try this:

package main

import (
  "io"; 
  )


func main() {
  contents,_ := io.ReadFile("filename");
  println(string(contents));
  io.WriteFile("filename", contents, 0644);
}

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    [CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [smalldatetime] NOT NULL

)

PS I think a smalldatetime is good enough. You may decide differently.

Can you not do this at the "moment of impact" ?

In Sql Server, this is common:

Update dbo.MyTable 
Set 

ColA = @SomeValue , 
UpdateDS = CURRENT_TIMESTAMP
Where...........

Sql Server has a "timestamp" datatype.

But it may not be what you think.

Here is a reference:

http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx

Here is a little RowVersion (synonym for timestamp) example:

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)


INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Maybe a complete working example:

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS

BEGIN

Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where 
triggerInsertedTable.Name = myAlias.Name

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Matching on the "Name" value is probably not wise.

Try this more mainstream example with a SurrogateKey

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    SurrogateKey int not null Primary Key Identity (1001,1),
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS

BEGIN

   UPDATE dbo.Names
    SET UpdateTS = CURRENT_TIMESTAMP
    From  dbo.Names myAlias
    WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

The question is limited by 'with jQuery' but it might help some to know that the jQuery code given in the best answer here does the following underneath...this works with or without jQuery:

function decodeEntities(input) {
  var y = document.createElement('textarea');
  y.innerHTML = input;
  return y.value;
}

Below is a fast approach to remove a potential '\n' from a string saved by fgets().
It uses strlen(), with 2 tests.

char buffer[100];
if (fgets(buffer, sizeof buffer, stdin) != NULL) {

  size_t len = strlen(buffer);
  if (len > 0 && buffer[len-1] == '\n') {
    buffer[--len] = '\0';
  }

Now use buffer and len as needed.

This method has the side benefit of a len value for subsequent code. It can be easily faster than strchr(Name, '\n'). Ref YMMV, but both methods work.

buffer, from the original fgets() will not contain in "\n" under some circumstances:
A) The line was too long for buffer so only char preceding the '\n' is saved in buffer. The unread characters remain in the stream.
B) The last line in the file did not end with a '\n'.

If input has embedded null characters '\0' in it somewhere, the length reported by strlen() will not include the '\n' location.

Some other answers' issues:

1. strtok(buffer, "\n"); fails to remove the '\n' when buffer is "\n". From this answer - amended after this answer to warn of this limitation.

2. The following fails on rare occasions when the first char read by fgets() is '\0'. This happens when input begins with an embedded '\0'. Then buffer[len -1] becomes buffer[SIZE_MAX] accessing memory certainly outside the legitimate range of buffer. Something a hacker may try or found in foolishly reading UTF16 text files. This was the state of an answer when this answer was written. Later a non-OP edited it to include code like this answer's check for "".

   size_t len = strlen(buffer);
   if (buffer[len - 1] == '\n') {  // FAILS when len == 0
     buffer[len -1] = '\0';
   }
   

3. sprintf(buffer,"%s",buffer); is undefined behavior: Ref. Further, it does not save any leading, separating or trailing whitespace. Now deleted.

4. [Edit due to good later answer] There are no problems with the 1 liner buffer[strcspn(buffer, "\n")] = 0; other than performance as compared to the strlen() approach. Performance in trimming is usually not an issue given code is doing I/O - a black hole of CPU time. Should following code need the string's length or is highly performance conscious, use this strlen() approach. Else the strcspn() is a fine alternative.

this work for me

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

java.util.Stack inherits the synchronization overhead of java.util.Vector, which is usually not justified.

It inherits a lot more than that, though. The fact that java.util.Stack extends java.util.Vector is a mistake in object-oriented design. Purists will note that it also offers a lot of methods beyond the operations traditionally associated with a stack (namely: push, pop, peek, size). It's also possible to do search, elementAt, setElementAt, remove, and many other random-access operations. It's basically up to the user to refrain from using the non-stack operations of Stack.

For these performance and OOP design reasons, the JavaDoc for java.util.Stack recommends ArrayDeque as the natural replacement. (A deque is more than a stack, but at least it's restricted to manipulating the two ends, rather than offering random access to everything.)

netstat -a -n | find /c "10.240.199.9:8080"

it will give you number of sockets active on a specific IP and port(Server port number)

The answer accepted above is not fully accurate. According to information obtained by inspecting Android source code:

Resources.getDimension() and getDimensionPixelOffset()/getDimensionPixelSize() differ only in that the former returns float while the latter two return the same value rounded to int appropriatelly. For all of them, the return value is in raw pixels.

All three functions are implementedy by calling Resources.getValue() and converting thus obtained TypedValue by calling TypedValue.complexToDimension(), TypedValue.complexToDimensionPixelOffset() and TypedValue.complexToDimensionPixelSize(), respectively.

Therefore, if you want to obtain "raw" value together with the unit specified in XML source, call Resources.getValue() and use methods of the TypedValue class.

Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.

Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information, including certificates, certificate chains, root authority certificates, and private keys. Its contents can be cryptographically protected (with passwords) to keep private keys private and preserve the integrity of root certificates.

Windows uses .pvk for a private key file. I'm not sure what standard (if any) Windows follows for these. Hopefully they are PKCS #8 encoded keys. Emmanuel Bourg reports that these are a proprietary format. Some documentation is available.

You should never disclose your private key. These are contained in .pfx and .pvk files.

Generally, you only exchange your certificate (.cer) and the certificates of any intermediate issuers (i.e., the certificates of all of your CAs, except the root CA) with other parties.

This is an old question asked two years prior to my answer, I am going to post what worked for me anyways.

In my working directory I have two files: Dockerfile & provision.sh

Dockerfile:

FROM centos:6.8

# put the script in the /root directory of the container
COPY provision.sh /root

# execute the script inside the container
RUN /root/provision.sh

EXPOSE 80

# Default command
CMD ["/bin/bash"]

provision.sh:

#!/usr/bin/env bash

yum upgrade

I was able to make the file in the docker container executable by setting the file outside the container as executable chmod 700 provision.sh then running docker build . .

The JAVA_HOME you have above only points to the JRE, which does not contain the compiler. Set your JAVA_HOME to

/usr/lib/jvm/java-6-openjdk

...and try again.

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

By example:

# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

DocumentFilter ? It gives you the ability to manipulate.

Sorry. J am using Jython (Python in Java) - but easy to understand

def insertString(self,FilterBypass_fb, offset, text, AttributeSet_attrs):
    txt = self._jtext.getText()
    print('DocumentFilter-insertString:',offset,text,'old:',txt)
    FilterBypass_fb.insertString(offset, text.upper(), AttributeSet_attrs)

def replace(self,FilterBypass_fb, offset, length, text, AttributeSet_attrs):
    txt = self._jtext.getText()
    print('DocumentFilter-replace:',offset, length, text,'old:',txt)
    FilterBypass_fb.replace(offset, length, text.upper(), AttributeSet_attrs)

def remove(self,FilterBypass_fb, offset, length):
    txt = self._jtext.getText()
    print('DocumentFilter-remove:',offset, length, 'old:',txt)
    FilterBypass_fb.remove(offset, length)

// (java style ~example for ComboBox-jTextField)
cb = new ComboBox();
cb.setEditable( true );
cbEditor = cb.getEditor();
cbEditorComp = cbEditor.getEditorComponent();
cbEditorComp.getDocument().setDocumentFilter(new myComboBoxEditorDocumentFilter(cbEditorComp));

An array doesn't have an add method. You assign a value to an element of the array with num[i]=value;.

public static void main(String[] args) {
    int[] num = new int[args.length];
    for (int i=0; i < num.length; i++){
      int neki = Integer.parseInt(args[i]);
      num[i]=neki;
    }
}

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #. That will abort the commit.

So you can delete all lines so that the commit message is empty, then save the file:

You'll then get a message that says Aborting commit due to empty commit message..

EDIT:

You can also delete all the lines and the result will be exactly the same.

To delete all lines in vim (if that is your default editor), once you're in the editor, type gg to go to the first line, then dG to delete all lines. Finally, write and quit the file with wq and your commit will be aborted.

{ // json object node
    "formules": [ // json array formules
    { // json object 
      "formule": "Linear Motion", // string
      "url": "qp1"
    }

What you are doing

  Context context = null; // context is null 
    try {
        String jsonLocation = AssetJSONFile("formules.json", context);

So change to

   try {
        String jsonLocation = AssetJSONFile("formules.json", CatList.this);

To parse

I believe you get the string from the assests folder.

try
{
String jsonLocation = AssetJSONFile("formules.json", context);
JSONObject jsonobject = new JSONObject(jsonLocation);
JSONArray jarray = (JSONArray) jsonobject.getJSONArray("formules");
for(int i=0;i<jarray.length();i++)
{
JSONObject jb =(JSONObject) jarray.get(i);
String formula = jb.getString("formule");
String url = jb.getString("url");
}
} catch (IOException e) {
        e.printStackTrace();
} catch (JSONException e) {
        e.printStackTrace();
}

Call sys.exit.

this is my solution:

    public Bitmap Blend(Bitmap topImage1, Bitmap bottomImage1, PorterDuff.Mode Type) {

        Bitmap workingBitmap = Bitmap.createBitmap(topImage1);
        Bitmap topImage = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);

        Bitmap workingBitmap2 = Bitmap.createBitmap(bottomImage1);
        Bitmap bottomImage = workingBitmap2.copy(Bitmap.Config.ARGB_8888, true);

        Rect dest = new Rect(0, 0, bottomImage.getWidth(), bottomImage.getHeight());
        new BitmapFactory.Options().inPreferredConfig = Bitmap.Config.ARGB_8888;
        bottomImage.setHasAlpha(true);
        Canvas canvas = new Canvas(bottomImage);
        Paint paint = new Paint();

        paint.setXfermode(new PorterDuffXfermode(Type));

        paint.setFilterBitmap(true);
        canvas.drawBitmap(topImage, null, dest, paint);
        return bottomImage;
    }

usage :

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.SCREEN));

or

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.OVERLAY));

and the results :

Overlay mode :

Screen mode:

I know this is possible if the other application can attach itself to a win32 window handle. For example, we have a separate C# application that hosts a DirectX application inside one of its windows. I'm not familiar with the exact details of how this is implemented, but I think just passing the win32 Handle of your panel to the other application is enough for that application to attach its DirectX surface.

Sounds like mssql jdbc is buffering the entire resultset for you. You can add a connect string parameter saying selectMode=cursor or responseBuffering=adaptive. If you are on version 2.0+ of the 2005 mssql jdbc driver then response buffering should default to adaptive.

If you don't want to use the CLI and are working on Windows, a very simple solution is to use TortoiseGit, it has the "Delete (keep local)" Action in the menu which works fine.

I know this is a bit old, but I thought I would provide another tip. In my situation, I inherited this application that I had to maintain. The VS2008 project came with the same string in C/C++->OutputFIles->"ObjectFIleName" and "Program Database File Name" (for both platforms Win32 and x64). So when I built Win32 platform, it built fine, but when I tried to build x64, I got the error:

\Debug64\Objects\common.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'

Obviously, both patforms were storing common.obj at the same location, so when I tried to build x64, the linker took the existing object file, which was x86.

To fix I just replaced the existing string with the macro "$(IntDir)\" for x64 (no quotes), and made sure that the macro resolved to the correct path, as in the rest of the projects. That solved my problem.

For the latest versions of iOS, simply add UITraitCollection:

extension UITraitCollection {

    var isIpad: Bool {
        return horizontalSizeClass == .regular && verticalSizeClass == .regular
    }
}

and then within UIViewController just check:

if traitCollection.isIpad { ... }

I liked the Brian answer:

function is_array(o){
    // make sure an array has a class attribute of [object Array]
    var check_class = Object.prototype.toString.call([]);
    if(check_class === '[object Array]')    {
        // test passed, now check
        return Object.prototype.toString.call(o) === '[object Array]';
    } else{
        // may want to change return value to something more desirable
        return -1; 
    }
}

but you could just do like this:

return Object.prototype.toString.call(o) === Object.prototype.toString.call([]);

Both are supported. To quote the Arduino homepage,

The core libraries are written in C and C++ and compiled using avr-gcc

Note that C++ is a superset of C (well, almost), and thus can often look very similar. I am not an expert, but I guess that most of what you will program for the Arduino in your first year on that platform will not need anything but plain C.

Had the same problem here but a different solution worked.

First, I tried the following, none of which worked:

1. Load symbols as suggested by seanlitow

2. Remove/Add reference to PresentationFramework and PresentationCore

3. Restart system

The solution was to undo the last few changes I had made to my code. I had just added a couple radio buttons and event handlers for checked and unchecked events. After removing my recent changes everything compiled. I then added my exact changes back and everything compiled properly. I don't understand why this worked - only thing I can think of is a problem with my VS Solution. Anyway, if none of the other suggestions work, you might try reverting back your most recent changes. NOTE: if you close & re-open Visual Studio your undo history is lost.. so you might try this before you close VS.

If you are working with ASP.NET MVC, you can solve the problem by adding the MaxJsonLength to your result:

var jsonResult = Json(new
{
    draw = param.Draw,
    recordsTotal = count,
    recordsFiltered = count,
    data = result
}, JsonRequestBehavior.AllowGet);
jsonResult.MaxJsonLength = int.MaxValue;

I had the same problem. None of the solutions here worked. I had to completely reinstall eclipse and make a new workspace. Then it worked!

You can place these macros in your pch file and used at anywhere in project by using "SCREEN_WIDTH"

#define SCREEN_WIDTH                ((([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait) || ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)) ? [[UIScreen mainScreen] bounds].size.width : [[UIScreen mainScreen] bounds].size.height)

and "SCREEN_HEIGHT"

#define SCREEN_HEIGHT               ((([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait) || ([UIApplication sharedApplication].statusBarOrientation ==   UIInterfaceOrientationPortraitUpsideDown)) ? [[UIScreen mainScreen] bounds].size.height : [[UIScreen mainScreen] bounds].size.width)

Example of using:

CGSize calCulateSizze ;
calCulateSizze.width = SCREEN_WIDTH/2-8;
calCulateSizze.height = SCREEN_WIDTH/2-8;

You can't. XSS protection. Cross site contents can not be read by javascript. No major browser will allow you that. I'm sorry, but this is a design flaw, you should drop the idea.

EDIT

Note that if you have editing access to the website loaded into the iframe, you can use postMessage (also see the browser compatibility)

Suppose you have

boolean active;

Accessors method would be

public boolean isActive(){return this.active;}

public void setActive(boolean active){this.active = active;}

According to man(2)stat you can use the S_ISDIR macro on the st_mode field:

bool isdir = S_ISDIR(st.st_mode);

Side note, I would recommend using Boost and/or Qt4 to make cross-platform support easier if your software can be viable on other OSs.

You can override the default css rules with this:

.table tbody tr > td.success {
  background-color: #dff0d8 !important;
}

.table tbody tr > td.error {
  background-color: #f2dede !important;
}

.table tbody tr > td.warning {
  background-color: #fcf8e3 !important;
}

.table tbody tr > td.info {
  background-color: #d9edf7 !important;
}

.table-hover tbody tr:hover > td.success {
  background-color: #d0e9c6 !important;
}

.table-hover tbody tr:hover > td.error {
  background-color: #ebcccc !important;
}

.table-hover tbody tr:hover > td.warning {
  background-color: #faf2cc !important;
}

.table-hover tbody tr:hover > td.info {
  background-color: #c4e3f3 !important;
}

!important is needed as bootstrap actually colours the cells individually (afaik it's not possible to just apply background-color to a tr). I couldn't find any colour variables in my version of bootstrap but that's the basic idea anyway.

A quick check is to use the Math.floor method. I created a method to check a double for two or less decimal places below:

public boolean checkTwoDecimalPlaces(double valueToCheck) {

    // Get two decimal value of input valueToCheck 
    double twoDecimalValue = Math.floor(valueToCheck * 100) / 100;

    // Return true if the twoDecimalValue is the same as valueToCheck else return false
    return twoDecimalValue == valueToCheck;
}

Bootstrap 3 now has Responsive tables out of the box. Hooray! :)

You can check it here: https://getbootstrap.com/docs/3.3/css/#tables-responsive

Add a <div class="table-responsive"> surrounding your table and you should be good to go:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

To make it work on all layouts you can do this:

.table-responsive
{
    overflow-x: auto;
}

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

You can make the output just 4 and 24 using unlist:

unlist(gregexpr(pattern ='2',"the2quickbrownfoxeswere2tired"))
[1]  4 24

Getting the second largest number from an array is pretty easy in python, I have done with simple steps and put various ways of test cases and it gave the right answer every time. PS. I know it's for c but I just gave a simple solution to the question if done in python

n = int(input()) #taking number of elements in array
arr = map(int, input().split()) #taking differet elements
l=[]
s=set()
for i in arr: #putting all the elemnents in set to remove any duplicate number
    s.add(i)
for j in s:  #putting all element from the set in the list to sort and get the second largest number
    l.append(j)
l.sort()
c=len(l)
print(l[c-2]) #printing second largest number

I'm currently in the process of building a single page application. Here is what I have thus far that I believe would be answering your question. I have a base template (base.html) that has a div with the ng-view directive in it. This directive tells angular where to put the new content in. Note that I'm new to angularjs myself so I by no means am saying this is the best way to do it.

app = angular.module('myApp', []);                                                                             

app.config(function($routeProvider, $locationProvider) {                        
  $routeProvider                                                                
       .when('/home/', {                                            
         templateUrl: "templates/home.html",                                               
         controller:'homeController',                                
        })                                                                      
        .when('/about/', {                                       
            templateUrl: "templates/about.html",     
            controller: 'aboutController',  
        }) 
        .otherwise({                      
            template: 'does not exists'   
        });      
});

app.controller('homeController', [              
    '$scope',                              
    function homeController($scope,) {        
        $scope.message = 'HOME PAGE';                  
    }                                                
]);                                                  

app.controller('aboutController', [                  
    '$scope',                               
    function aboutController($scope) {        
        $scope.about = 'WE LOVE CODE';                       
    }

I have tried www.wheresmymac.com they are cheap and they have great bandwith so their is low latency. You need teamviewer to log into the virtual system though

If you are in a submodule, don't forget to declare the module in main app. ie :

<scrip>
angular.module('mainApp', ['subModule1', 'subModule2']);

angular.module('subModule1')
   .controller('MyController', ['$scope', function($scope) {
      $scope.moduleName = 'subModule1';
   }]);
</script>
...
<div ng-app="mainApp">
   <div ng-controller="MyController">
   <span ng-bind="moduleName"></span>
</div>

If you don't declare subModule1 in mainApp, you will got a "[ng:areq] Argument "MyController" is not a function, got undefined.

If you need to scroll to a point of an element. You can use Jquery function to scroll it up/down.

$('html, body').animate({
                scrollTop: $("#div1").offset().top
            }, 'slow');

git reset --hard origin/master

says: throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master.

You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".

Slightly simpler:

def round_int(x):
    return 10 * ((x + 5) // 10)

1 ) Only the copy of reference is sent as a value to the formal parameter. When the formal parameter variable is assigned other value ,the formal parameter's reference changes but the actual parameter's reference remain the same incase of this integer object.

public class UnderstandingObjects {

public static void main(String[] args) {

    Integer actualParam = new Integer(10);

    changeValue(actualParam);

    System.out.println("Output " + actualParam); // o/p =10

    IntObj obj = new IntObj();

    obj.setVal(20);

    changeValue(obj);

    System.out.println(obj.a); // o/p =200

}

private static void changeValue(Integer formalParam) {

    formalParam = 100;

    // Only the copy of reference is set to the formal parameter
    // this is something like => Integer formalParam =new Integer(100);
    // Here we are changing the reference of formalParam itself not just the
    // reference value

}

private static void changeValue(IntObj obj) {
    obj.setVal(200);

    /*
     * obj = new IntObj(); obj.setVal(200);
     */
    // Here we are not changing the reference of obj. we are just changing the
    // reference obj's value

    // we are not doing obj = new IntObj() ; obj.setValue(200); which has happend
    // with the Integer

}

}

class IntObj { Integer a;

public void setVal(int a) {
    this.a = a;
}

}

I have multiple version of Xcode installed at the same time. The framework was built with a newer version of Xcode. The app that I tried to compile was with an older version of Xcode. When I cleaned and compiled both the framework and the app with the same version of Xcode then things worked.

I had this same issue. I had copied a view "Movie" and renamed it "Customer" accordingly. I also did the same with the models and the controllers.

The resolution was this...I rename the Customer View to Customer1 and just created a new view and called it Customer....I then just copied the Customer1 code into Customer.

This worked.

I would love to know the real cause of the problem.

UPDATE Just for grins....I went back and replicated all the renaming scenario again...and did not get any errors.

I know it's not related to the image load but here what I did in one of the job interview test.

Demo

add Location to your constructor from @angular/common

constructor(private _location: Location) {}

add the back function:

back() {
  this._location.back();
}

and then in your view:

<button class="btn" (click)="back()">Back</button>

Option 1: Put this in your procedure to print 'comment' to stdout when it runs.

SELECT 'Comment';

Option 2: Put this in your procedure to print a variable with it to stdout:

declare myvar INT default 0;
SET myvar = 5;
SELECT concat('myvar is ', myvar);

This prints myvar is 5 to stdout when the procedure runs.

Option 3, Create a table with one text column called tmptable, and push messages to it:

declare myvar INT default 0;
SET myvar = 5;
insert into tmptable select concat('myvar is ', myvar);

You could put the above in a stored procedure, so all you would have to write is this:

CALL log(concat('the value is', myvar));

Which saves a few keystrokes.

Option 4, Log messages to file

select "penguin" as log into outfile '/tmp/result.txt';

There is very heavy restrictions on this command. You can only write the outfile to areas on disk that give the 'others' group create and write permissions. It should work saving it out to /tmp directory.

Also once you write the outfile, you can't overwrite it. This is to prevent crackers from rooting your box just because they have SQL injected your website and can run arbitrary commands in MySQL.

This works 100%

window.open('http://www.google.com/','_newtab' + Date.now());

autocomplete="off" this should fix the issue for all modern browsers.

<form name="form1" id="form1" method="post" autocomplete="off"
   action="http://www.example.com/form.cgi">
  [...]
</form>

In current versions of Gecko browsers, the autocomplete attribute works perfectly. For earlier versions, going back to Netscape 6.2, it worked with the exception for forms with "Address" and "Name"

Update

In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:

autocomplete="nope"

Since this random value is not a valid one, the browser will give up.

Documetation

Little bit late to the party but had some problems with getting something useful out from a ReadableStream produced from a Odata $batch request using the Sharepoint Framework.

Had similar issues as OP, but the solution in my case was to use a different conversion method than .json(). In my case .text() worked like a charm. Some fiddling was however necessary to get some useful JSON from the textfile.

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object).

At most one parameter is allowed to read from the message body. So this will not work:

// Caution: Will not work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

Please go through the website for more details: https://docs.microsoft.com/en-us/aspnet/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

In this case you need to go up to the <tr> then use .next(), like this:

$(obj).closest('tr').next().find('.class');

Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this:

$(obj).closest('tr').nextAll(':has(.class):first').find('.class');

The canvas element provides a toDataURL method which returns a data: URL that includes the base64-encoded image data in a given format. For example:

var jpegUrl = canvas.toDataURL("image/jpeg");
var pngUrl = canvas.toDataURL(); // PNG is the default

Although the return value is not just the base64 encoded binary data, it's a simple matter to trim off the scheme and the file type to get just the data you want.

The toDataURL method will fail if the browser thinks you've drawn to the canvas any data that was loaded from a different origin, so this approach will only work if your image files are loaded from the same server as the HTML page whose script is performing this operation.

For more information see the MDN docs on the canvas API, which includes details on toDataURL, and the Wikipedia article on the data: URI scheme, which includes details on the format of the URI you'll receive from this call.

1) Locate server.xml in {Tomcat installation folder}\ conf \ 2) Find following similar statement

       <!-- Define a non-SSL HTTP/1.1 Connector on port 8180 -->
      <Connector port="8080" maxHttpHeaderSize="8192"

if you use Picasso change to Glide like this.

Remove picasso

Picasso.get().load(Uri.parse("url")).into(imageView)

Change Glide

Glide.with(context).load("url").into(imageView)

More efficient Glide than Picasso draw to large bitmap

The first answer is good for understanding how it works. But I wanted to understand how I should be using it in practice.

SUMMARY

• for moderately imbalanced data WITHOUT noise, there is not much of a difference in applying class weights
• for moderately imbalanced data WITH noise and strongly imbalanced, it is better to apply class weights
• param class_weight="balanced" works decent in the absence of you wanting to optimize manually
• with class_weight="balanced" you capture more true events (higher TRUE recall) but also you are more likely to get false alerts (lower TRUE precision)
  • as a result, the total % TRUE might be higher than actual because of all the false positives
  • AUC might misguide you here if the false alarms are an issue
• no need to change decision threshold to the imbalance %, even for strong imbalance, ok to keep 0.5 (or somewhere around that depending on what you need)

NB

The result might differ when using RF or GBM. sklearn does not have class_weight="balanced" for GBM but lightgbm has LGBMClassifier(is_unbalance=False)

since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of

"scale_area()" and nows uses scale_size_area()
"opts()" has changed to theme()

In my answer,I have stored the plot in mygraph variable and then I have used

mygraph$labels$x="Discharge of materials" #changes x axis title
       mygraph$labels$y="Area Affected" # changes y axis title

And the work is done. Below is the complete answer.

install.packages("Sleuth2")
library(Sleuth2)
library(ggplot2)

ex1221new<-data.frame(Discharge<-c(100:109),Area<-c(120:129),NO3<-seq(2,5,length.out = 10))
discharge<-ex1221new$Discharge
area<-ex1221new$Area
nitrogen<-ex1221new$NO3
p <- ggplot(ex1221new, aes(discharge, area), main="Point")
mygraph<-p + geom_point(aes(size= nitrogen)) + 
  scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")+
theme(
 plot.title =  element_text(color="Blue", size=30, hjust = 0.5), 

 # change the styling of both the axis simultaneously from this-
 axis.title = element_text(color = "Green", size = 20, family="Courier",)
 

   # you can change the  axis title from the code below
   mygraph$labels$x="Discharge of materials" #changes x axis title
   mygraph$labels$y="Area Affected" # changes y axis title
   mygraph



   

Also, you can change the labels title from the same formula used above -

mygraph$labels$size= "N2" #size contains the nitrogen level 

No, just include the different fields in the "ON" clause of 1 inner join statement:

SELECT * from Evalulation e JOIN Value v ON e.CaseNum = v.CaseNum
    AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum

You need to link both a.o and b.o:

gcc -o program a.c b.c

If you have a main() in each file, you cannot link them together.

However, your a.c file contains a reference to doSomething() and expects to be linked with a source file that defines doSomething() and does not define any function that is defined in a.c (such as main()).

You cannot call a function in Process B from Process A. You cannot send a signal to a function; you send signals to processes, using the kill() system call.

The signal() function specifies which function in your current process (program) is going to handle the signal when your process receives the signal.

You have some serious work to do understanding how this is going to work - how ProgramA is going to know which process ID to send the signal to. The code in b.c is going to need to call signal() with dosomething as the signal handler. The code in a.c is simply going to send the signal to the other process.

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

I just ran into another cause for this error that you can check for.

The base class defined a pure virtual function as:

virtual int foo(int x = 0);

And the subclass had

int foo(int x) override;

The problem was the typo that the "=0" was supposed to be outside of the parenthesis:

virtual int foo(int x) = 0;

So, in case you're scrolling this far down, you probably didn't find the answer - this is something else to check for.

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

1. ADD THIS

**<HEAD>**

  < link rel="icon" href="directory/image.png">

Then run and enjoy it

If you just want to get the minimum of a list, instead of sorting it and then getting the first element (O(N log N)), you can use do it in linear time using min:

<T extends Object & Comparable<? super T>> T min(Collection<? extends T> coll)

That looks gnarly at first, but looking at your previous questions, you have a List<String>. In short: min works on it.

For the long answer: all that super and extends stuff in the generic type constraints is what Josh Bloch calls the PECS principle (usually presented next to a picture of Arnold -- I'M NOT KIDDING!)

Producer Extends, Consumer Super

It essentially makes generics more powerful, since the constraints are more flexible while still preserving type safety (see: what is the difference between ‘super’ and ‘extends’ in Java Generics)

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

You can use the % operator to find the remainder of a division, and compare the result with 0.

Example:

if (number % divisor == 0)
{
    //code for perfect divisor
}
else
{
    //the number doesn't divide perfectly by divisor
}

String toCamelCase(String string) {
    StringBuffer sb = new StringBuffer(string);
    sb.replace(0, 1, string.substring(0, 1).toUpperCase());
    return sb.toString();

}

Further to what Steve Baker has said, you can find a description of the SIOCGIFCONF ioctl in the netdevice(7) man page.

Once you have the list of all the IP addresses on the host, you will have to use application specific logic to filter out the addresses you do not want and hope you have one IP address left.

Try replacing <%# Eval("item") %> with <%# If(Eval("item"), "0 value") %> (or <%# Eval("item") ?? "0 value" %>, when using C#).

def extended_string (word, length) :

    extra_long_word = word * (length//len(word) + 1)
    required_string = extra_long_word[:length]
    return required_string

print(extended_string("abc", 7))

xml was not in the WEB-INF folder, thats why i was getting this error, make sure that web.xml and xxx-servlet.xml is inside WEB_INF folder and not in the webapp folder .

using is used when you have a resource that you want disposed after it's been used.

For instance if you allocate a File resource and only need to use it in one section of code for a little reading or writing, using is helpful for disposing of the File resource as soon as your done.

The resource being used needs to implement IDisposable to work properly.

Example:

using (File file = new File (parameters))
{
    *code to do stuff with the file*
}

function googleTranslateElementInit() {
  new google.translate.TranslateElement(
    {pageLanguage: 'en'},
    'google_translate_element'
  );
}

On Windows pip3 should be in the Scripts path of your Python installation:

C:\path\to\python\Scripts\pip3

Use:

where python

to find out where your Python executable(s) is/are located. The result should look like this:

C:\path\to\python\python.exe

or:

C:\path\to\python\python3.exe

You can check if pip3 works with this absolute path:

C:\path\to\python\Scripts\pip3

if yes, add C:\path\to\python\Scripts to your environmental variable PATH .

Your code:

import matplotlib.pyplot as plt
import matplotlib.image as mpimg

What it should be:

plt.imshow(mpimg.imread('MyImage.png'))
File_name = mpimg.imread('FilePath')
plt.imshow(FileName)
plt.show()

you're missing a plt.show() unless you're in Jupyter notebook, other IDE's do not automatically display plots so you have to use plt.show() each time you want to display a plot or made a change to an existing plot in follow up code.

Create index.html or index.php file in root directory (in your case - /var/www/html, as @jabaldonedo mentioned)

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

I had similar message and after several searches online and doing all suggestions, nothing helped. Finally I found the solution. In my IIS server, under the application pool advance option, there is an option for "Enable 32-Bit Applications" - that was changed from false to true and after restarting IIS server, My program started generating pdf files.

All the answers so far here seems to have one or more of these problems: (1) it may not work on VC++ (2) it requires additional dependencies like boost or fmt (3) its too complicated custom implementation and probably not tested well.

Below code addresses all of above issues.

#include <string>
#include <cstdarg>
#include <memory>

std::string stringf(const char* format, ...)
{
    va_list args;
    va_start(args, format);
    #ifndef _MSC_VER

        //GCC generates warning for valid use of snprintf to get
        //size of result string. We suppress warning with below macro.
        #ifdef __GNUC__
        #pragma GCC diagnostic push
        #pragma GCC diagnostic ignored "-Wformat-nonliteral"
        #endif

        size_t size = std::snprintf(nullptr, 0, format, args) + 1; // Extra space for '\0'

        #ifdef __GNUC__
        # pragma GCC diagnostic pop
        #endif

        std::unique_ptr<char[]> buf(new char[ size ] ); 
        std::vsnprintf(buf.get(), size, format, args);
        return std::string(buf.get(), buf.get() + size - 1 ); // We don't want the '\0' inside
    #else
        int size = _vscprintf(format, args);
        std::string result(++size, 0);
        vsnprintf_s((char*)result.data(), size, _TRUNCATE, format, args);
        return result;
    #endif
    va_end(args);
}    

int main() {
    float f = 3.f;
    int i = 5;
    std::string s = "hello!";
    auto rs = stringf("i=%d, f=%f, s=%s", i, f, s.c_str());
    printf("%s", rs.c_str());
    return 0;
}

Notes:

1. Separate VC++ code branch is necessary because VC++ has decided to deprecate snprintf which will generate compiler warnings for other highly voted answers above. As I always run in "warnings as errors" mode, its no go for me.
2. The function accepts char * instead of std::string. This because most of the time this function would be called with literal string which is indeed char *, not std::string. In case you do have std::string as format parameter, then just call .c_str().
3. Name of the function is stringf instead of things like string_format to keepup with printf, scanf etc.
4. It doesn't address safety issue (i.e. bad parameters can potentially cause seg fault instead of exception). If you need this then you are better off with boost or fmt libraries. My preference here would be fmt because it is just one header and source file to drop in the project while having less weird formatting syntax than boost. However both are non-compatible with printf format strings so below is still useful in that case.
5. The stringf code passes through GCC strict mode compilation. This requires extra #pragma macros to suppress false positives in GCC warnings.

Above code was tested on,

• GCC 4.9.2/C++11/C++14
• VC++ compiler ver 19.0
• Clang 3.7.0

ClassFinder is a program that's designed to solve this problem. It allows you to search recursively through directories and jar files to find all instances of a class matching a pattern. It is written in Java, not python. It has a nice GUI which makes it easy to use. And it runs fast. This release is precompiled in a runnable jar so you don't have to build it from source.

from itertools import product, combinations


fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_aspect("equal")

        ax.plot3D(*zip(s, e), color="b")

# draw sphere
u, v = np.mgrid[0:2*np.pi:20j, 0:np.pi:10j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
ax.plot_wireframe(x, y, z, color="r")

# draw a point
ax.scatter([0], [0], [0], color="g", s=100)

# draw a vector

plt.show()

PHP > 5.3 use fgetcsv() or str_getcsv(). Couldn't be simpler.

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.

Additional data (in case you have more questions):

FOO: {
       for my $i ( @listone ){
          for my $j ( @listtwo ){
                 if ( cond( $i,$j ) ){

You can attempt to push the cookie val to another domain using an image tag.

Your mileage may vary when trying to do this because some browsers require you to have a proper P3P Policy on the WebApp2 domain or the browser will reject the cookie.

If you look at plus.google.com p3p policy you will see that their policy is:

CP="This is not a P3P policy! See http://www.google.com/support/accounts/bin/answer.py?hl=en&answer=151657 for more info."

that is the policy they use for their +1 buttons to these cross domain requests.

Another warning is that if you are on https make sure that the image tag is pointing to an https address also otherwise the cookies will not set.

I couldn't get this working. Started with PHP 5.3, then tried to switch to PHP 5.28 from xampp-win32-1.7.0.zip. Couldn't get it to work. Then, I got smart and figured out i was working with XAMPP and you can install it wherever you want, so I did a fresh install from scratch with xampp-win32-1.7.0.zip. The whole point of working with XAMPP is so you don't have to fuss with the sysadmin stuff. Using it in that context got me up and running in no time.

When using System.Net.WebRequest your application will negotiate with the server to determine the highest TLS version that both your application and the server support, and use this. You can see more details on how this works here:

http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_handshake

If the server doesn't support TLS it will fallback to SSL, therefore it could potentially fallback to SSL3. You can see all of the versions that .NET 4.5 supports here:

http://msdn.microsoft.com/en-us/library/system.security.authentication.sslprotocols(v=vs.110).aspx

In order to prevent your application being vulnerable to POODLE, you can disable SSL3 on the machine that your application is running on by following this explanation:

https://serverfault.com/questions/637207/on-iis-how-do-i-patch-the-ssl-3-0-poodle-vulnerability-cve-2014-3566

You can simply use jQuery’s delay() method to set the delay time interval.

HTML code:

  <div class="box"></div>

JQuery code:

  $(document).ready(function(){ 
    $(".show-box").click(function(){
      $(this).text('loading...').delay(1000).queue(function() {
        $(this).hide();
        showBox(); 
        $(this).dequeue();
      });        
    });
  });

Clarification (thanks @vgm64): if you're already in Terminal, this lets you quickly change to the topmost Finder window without leaving Terminal. This way, you can avoid using the mouse.

I've added the following to my .bash_profile so I can type cdff in Terminal at any time.

function ff { osascript -e 'tell application "Finder"'\
 -e "if (${1-1} <= (count Finder windows)) then"\
 -e "get POSIX path of (target of window ${1-1} as alias)"\
 -e 'else' -e 'get POSIX path of (desktop as alias)'\
 -e 'end if' -e 'end tell'; };\

function cdff { cd "`ff $@`"; };

This is from this macosxhints.com Terminal hint.

Just add like this in case 1: like this

 case 0:
     list = DBAdpter.requestUserData(assosiatetoken);
     Collections.sort(list, byDate);
     for (int i = 0; i < list.size(); i++) {
         if (list.get(i).lastModifiedDate != null) {
             lv.setAdapter(new MyListAdapter(
                     getApplicationContext(), list));
         }
     }
     break;

and put this method at end of the your class

static final Comparator<All_Request_data_dto> byDate = new Comparator<All_Request_data_dto>() {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");

    public int compare(All_Request_data_dto ord1, All_Request_data_dto ord2) {
        Date d1 = null;
        Date d2 = null;
        try {
            d1 = sdf.parse(ord1.lastModifiedDate);
            d2 = sdf.parse(ord2.lastModifiedDate);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


        return (d1.getTime() > d2.getTime() ? -1 : 1);     //descending
    //  return (d1.getTime() > d2.getTime() ? 1 : -1);     //ascending
    }
};

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

String.Format also works in Razor:

String.Format("{0} - {1}", Model.address, Model.city)

This isn't strictly SQL language, but in SQL Server if your database collation is case-sensitive, then all table names are case-sensitive.

https://www.cloudjojo.com/how-to-connect-ec2-machine-with-ftp/

1. First you have to install some ftp server on your ec2 machine like vsftpd.
2. Configure vsftpd config file to allow writes and open ports.
3. Create user for ftp client.
4. Connect with ftp client like filezilla.

Make sure you open port 21 on aws security group.

I had the same issue recently on my test server. After searching for reasons this might be happening and testing the solutions I found here, I recalled that I had clicked the "Stop this page from creating pop-ups" option a few hours before when the script I was working on was wildly popping up alerts.

The solution was as simple as closing the tab and opening a fresh one!

An array is a pointer. It points to the start of a sequence of "objects".

If we do this: ìnt arr[10];, then arr is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];.

You can specify an empty string as an argument to join, if no argument is specified a comma is used.

 arr.join('');

http://jsfiddle.net/mowglisanu/CVr25/1/

I think there is no need to specify

'http://localhost:8080`" 

in the URI part.. because. if you specify it, You'll have to change it manually for every environment.

Only

"/restws/json/product/get" also works

You have an error in you script tag construction, this:

<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

Should look like this:

<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.

UPDATE

But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

on your terminal run this command on your ionic project folder ionic info and you will get the following :

This one will only remove empty values and not falsey ones, which I think is more desirable.

There is an option to also remove null values.

This method should be much faster than using splice.

    function cleanArray(a, removeNull) {
        var i, l, temp = [];
        l = a.length;
        if (removeNull) {
            for (i = 0; i < l; i++) {
                if (a[i] !== undefined && a[i] !== null) {
                    temp.push(a[i]);
                }
            }
        } else {
            for (i = 0; i < l; i++) {
                if (a[i] !== undefined) {
                    temp.push(a[i]);
                }
            }
        }
        a.length = 0;
        l = temp.length;
        for (i = 0; i < l; i++) {
            a[i] = temp[i];
        }
        temp.length = 0;
        return a;
    }
    var myArray = [1, 2, , 3, , 3, , , 0, , null, false, , NaN, '', 4, , 4, , 5, , 6, , , , ];
    cleanArray(myArray);
    myArray;

Improved code to return the duplicate elements

• Can find duplicates in a Collection
• return the set of duplicates
• Unique Elements can be obtained from the Set

public static <T> List getDuplicate(Collection<T> list) {

    final List<T> duplicatedObjects = new ArrayList<T>();
    Set<T> set = new HashSet<T>() {
    @Override
    public boolean add(T e) {
        if (contains(e)) {
            duplicatedObjects.add(e);
        }
        return super.add(e);
    }
    };
   for (T t : list) {
        set.add(t);
    }
    return duplicatedObjects;
}


public static <T> boolean hasDuplicate(Collection<T> list) {
    if (getDuplicate(list).isEmpty())
        return false;
    return true;
}

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

bind is deprecated. Use on:

$("#textarea").on('change keyup paste', function() {
    // your code here
});

Note: The code above will fire multiple times, once for each matching trigger-type. To handle that, do something like this:

var oldVal = "";
$("#textarea").on("change keyup paste", function() {
    var currentVal = $(this).val();
    if(currentVal == oldVal) {
        return; //check to prevent multiple simultaneous triggers
    }

    oldVal = currentVal;
    //action to be performed on textarea changed
    alert("changed!");
});

To complement the existing helpful answers:

Using Bash's own regex-matching operator, =~, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:

set -- '12-34-5678' # set $1 to sample value

kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match

Note, however, that the caveat re using flavor-specific regex constructs such as \d equally applies: While =~ supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.

To remain portable (in the context of Bash), stick to the POSIX ERE specification.

Note that =~ even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]} array variable.

Further notes:

• $kREGEX_DATE is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).

• While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \.

  • E.g., on Linux, where \< is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes does.

• I've changed variable name REGEX_DATE to kREGEX_DATE (k signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.

Here is the code that I am using:

Inside WebViewClient:

               @Override
             public void onPageStarted(WebView view, String url, Bitmap favicon) {

              super.onPageStarted(view, url, favicon);
              findViewById(R.id.progress1).setVisibility(View.VISIBLE);
             }

            @Override
            public void onPageFinished(WebView view, String url) {
                findViewById(R.id.progress1).setVisibility(View.GONE);
            }

Here is the XML :

<ProgressBar
    android:id="@+id/progress1"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Hope this helps..

Heres a variant on WWs answer, it includes partitions and sub-partitions as others above have suggested, plus a column to show the TYPE: Table/Index/LOB etc

SELECT
   owner, "Type", table_name "Name", TRUNC(sum(bytes)/1024/1024) Meg
FROM
(  SELECT segment_name table_name, owner, bytes, 'Table' as "Type"
   FROM dba_segments
   WHERE segment_type in  ('TABLE','TABLE PARTITION','TABLE SUBPARTITION')
 UNION ALL
   SELECT i.table_name, i.owner, s.bytes, 'Index' as "Type"
   FROM dba_indexes i, dba_segments s
   WHERE s.segment_name = i.index_name
   AND   s.owner = i.owner
   AND   s.segment_type in ('INDEX','INDEX PARTITION','INDEX SUBPARTITION')
 UNION ALL
   SELECT l.table_name, l.owner, s.bytes, 'LOB' as "Type"
   FROM dba_lobs l, dba_segments s
   WHERE s.segment_name = l.segment_name
   AND   s.owner = l.owner
   AND   s.segment_type IN ('LOBSEGMENT','LOB PARTITION','LOB SUBPARTITION')
 UNION ALL
   SELECT l.table_name, l.owner, s.bytes, 'LOB Index' as "Type"
   FROM dba_lobs l, dba_segments s
   WHERE s.segment_name = l.index_name
   AND   s.owner = l.owner
   AND   s.segment_type = 'LOBINDEX')
   WHERE owner in UPPER('&owner')
GROUP BY table_name, owner, "Type"
HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
ORDER BY SUM(bytes) desc;

Use String#next as the counter.

>> n = "000"
>> 3.times { puts "file_#{n.next!}" }
file_001
file_002
file_003

next is relatively 'clever', meaning you can even go for

>> n = "file_000"
>> 3.times { puts n.next! }
file_001
file_002
file_003

I have used a syntax like this before:

$(ProjectDir)..\headers

or

..\headers

As other have pointed out, the starting directory is the one your project file is in(vcproj or vcxproj), not where your main code is located.

Like @maerics said, your target machine and browser will determine performance.

But for some real world numbers, on my 2017 enterprise Chromebook, running the operation:

console.time();
Array(x).fill(0).filter(x => x < 6).length
console.timeEnd();

• x=5e4 takes 16ms, good enough for 60fps
• x=4e6 takes 250ms, which is noticeable but not a big deal
• x=3e7 takes 1300ms, which is pretty bad
• x=4e7 takes 11000ms and allocates an extra 2.5GB of memory

So around 30 million elements is a hard upper limit, because the javascript VM falls off a cliff at 40 million elements and will probably crash the process.

EDIT: In the code above, I'm actually filling the array with elements and looping over them, simulating the minimum of what an app might want to do with an array. If you just run Array(2**32-1) you're creating a sparse array that's closer to an empty JavaScript object with a length, like {length: 4294967295}. If you actually tried to use all those 4 billion elements, you'll definitely your user's javascript process.

This should be working: jdbc:oracle:thin//hostname:Port/ServiceName=SERVICE_NAME

A key issue here is that this loop iterates over the rows (1st dimension) of B:

In [258]: B
Out[258]: 
array([[ 0,  1,  2],
       [ 3,  4,  5],
       [ 6,  7,  8],
       [ 9, 10, 11]])
In [259]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b += 1
     ...:     print(b)
     ...:     
[0 1 2] =>[1 2 3]
[3 4 5] =>[4 5 6]
[6 7 8] =>[7 8 9]
[ 9 10 11] =>[10 11 12]

Thus the += is acting on a mutable object, an array.

This is implied in the other answers, but easily missed if your focus is on the a = a+1 reassignment.

I could also make an in-place change to b with [:] indexing, or even something fancier, b[1:]=0:

In [260]: for b in B:
     ...:     print(b,'=>',end='')
     ...:     b[:] = b * 2

[1 2 3] =>[2 4 6]
[4 5 6] =>[ 8 10 12]
[7 8 9] =>[14 16 18]
[10 11 12] =>[20 22 24]

Of course with a 2d array like B we usually don't need to iterate on the rows. Many operations that work on a single of B also work on the whole thing. B += 1, B[1:] = 0, etc.

You can use sshpass for it. Below are the steps

1. Install sshpass For Ubuntu - sudo apt-get install sshpass
2. Add the Remote IP to your known-host file if it is first time For Ubuntu -> ssh user@IP -> enter 'yes'
3. give a combined command of scp and sshpass for it. Below is a sample code for war coping to remote tomcat sshpass -p '#Password_For_remote_machine' scp /home/ubuntu/latest_build/abc.war #user@#RemoteIP:/var/lib/tomcat7/webapps

This one liner replaces all the ^M characters:

dos2unix <file-name>

You can call this from inside Perl or directly on your Unix prompt.

I came here looking for exporting blob into file with least effort. CLR functions is not something what I'd call least effort. Here described lazier one, using OLE Automation:

declare @init int
declare @file varbinary(max) = CONVERT(varbinary(max), N'your blob here')
declare @filepath nvarchar(4000) = N'c:\temp\you file name here.txt'

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1; 
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @file; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @filepath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources

You'll potentially need to allow to run OA stored procedures on server (and then turn it off, when you're done):

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

There are a few things which new does that malloc doesn’t:

1. new constructs the object by calling the constructor of that object
2. new doesn’t require typecasting of allocated memory.
3. It doesn’t require an amount of memory to be allocated, rather it requires a number of objects to be constructed.

So, if you use malloc, then you need to do above things explicitly, which is not always practical. Additionally, new can be overloaded but malloc can’t be.

In a word, if you use C++, try to use new as much as possible.

1) HTML is downloaded.

2) HTML is parsed progressively. When a request for an asset is reached the browser will attempt to download the asset. A default configuration for most HTTP servers and most browsers is to process only two requests in parallel. IE can be reconfigured to downloaded an unlimited number of assets in parallel. Steve Souders has been able to download over 100 requests in parallel on IE. The exception is that script requests block parallel asset requests in IE. This is why it is highly suggested to put all JavaScript in external JavaScript files and put the request just prior to the closing body tag in the HTML.

3) Once the HTML is parsed the DOM is rendered. CSS is rendered in parallel to the rendering of the DOM in nearly all user agents. As a result it is strongly recommended to put all CSS code into external CSS files that are requested as high as possible in the <head></head> section of the document. Otherwise the page is rendered up to the occurance of the CSS request position in the DOM and then rendering starts over from the top.

4) Only after the DOM is completely rendered and requests for all assets in the page are either resolved or time out does JavaScript execute from the onload event. IE7, and I am not sure about IE8, does not time out assets quickly if an HTTP response is not received from the asset request. This means an asset requested by JavaScript inline to the page, that is JavaScript written into HTML tags that is not contained in a function, can prevent the execution of the onload event for hours. This problem can be triggered if such inline code exists in the page and fails to execute due to a namespace collision that causes a code crash.

Of the above steps the one that is most CPU intensive is the parsing of the DOM/CSS. If you want your page to be processed faster then write efficient CSS by eliminating redundent instructions and consolidating CSS instructions into the fewest possible element referrences. Reducing the number of nodes in your DOM tree will also produce faster rendering.

Keep in mind that each asset you request from your HTML or even from your CSS/JavaScript assets is requested with a separate HTTP header. This consumes bandwidth and requires processing per request. If you want to make your page load as fast as possible then reduce the number of HTTP requests and reduce the size of your HTML. You are not doing your user experience any favors by averaging page weight at 180k from HTML alone. Many developers subscribe to some fallacy that a user makes up their mind about the quality of content on the page in 6 nanoseconds and then purges the DNS query from his server and burns his computer if displeased, so instead they provide the most beautiful possible page at 250k of HTML. Keep your HTML short and sweet so that a user can load your pages faster. Nothing improves the user experience like a fast and responsive web page.

This is easily accomplished with jQuery's clone() function.

So you must create two wrapper divs for the recaptcha. My first form's recaptcha div:

<div id="myrecap">
    <?php
        require_once('recaptchalib.php');
        $publickey = "XXXXXXXXXXX-XXXXXXXXXXX";
        echo recaptcha_get_html($publickey);
    ?>
</div>

The second form's div is empty (different ID). So mine is just:

<div id="myraterecap"></div>

Then the javascript is quite simple:

$(document).ready(function() {
    // Duplicate our reCapcha 
    $('#myraterecap').html($('#myrecap').clone(true,true));
});

Probably don't need the second parameter with a true value in clone(), but doesn't hurt to have it... The only issue with this method is if you are submitting your form via ajax, the problem is that you have two elements that have the same name and you must me a bit more clever with the way you capture that correct element's values (the two ids for reCaptcha elements are #recaptcha_response_field and #recaptcha_challenge_field just in case someone needs them)

Try to use:

String buttonText = ((Button)v).getText().toString();

@Test(expected = Exception.class)  

Tells Junit that exception is the expected result so test will be passed (marked as green) when exception is thrown.

For

@Test

Junit will consider test as failed if exception is thrown, provided it's an unchecked exception. If the exception is checked it won't compile and you will need to use other methods. This link might help.

For merging small sets, using the above function is fine. However, if you are merging large amounts of data, I'd suggest looking into http://mbk.projects.postgresql.org

The current best practice that I'm aware of is:

1. COPY new/updated data into temp table (sure, or you can do INSERT if the cost is ok)
2. Acquire Lock [optional] (advisory is preferable to table locks, IMO)
3. Merge. (the fun part)

To put space between CollectionItems use this

write this two Line in viewdidload

UICollectionViewFlowLayout *collectionViewLayout = (UICollectionViewFlowLayout*)self.collectionView.collectionViewLayout;
collectionViewLayout.sectionInset = UIEdgeInsetsMake(<CGFloat top>, <CGFloat left>, <CGFloat bottom>, <CGFloat right>)

If you need to print it and don't need a newline, you can use:

printf $(md5sum filename)

$('#userid').change(function(){
  //fire your ajax call  
});

$('#userid').val(10).change();

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

In my case I got this error because of a line

Chrome tried to interpret the current HTML file then as javascript.

git rm --cached is used to remove a file from the index. In the case where the file is already in the repo, git rm --cached will remove the file from the index, leaving it in the working directory and a commit will now remove it from the repo as well. Basically, after the commit, you would have unversioned the file and kept a local copy.

git reset HEAD file ( which by default is using the --mixed flag) is different in that in the case where the file is already in the repo, it replaces the index version of the file with the one from repo (HEAD), effectively unstaging the modifications to it.

In the case of unversioned file, it is going to unstage the entire file as the file was not there in the HEAD. In this aspect git reset HEAD file and git rm --cached are same, but they are not same ( as explained in the case of files already in the repo)

To the question of Why are there 2 ways to unstage a file in git? - there is never really only one way to do anything in git. that is the beauty of it :)

The other answers have one problem: they rely on the action you do and not on the link itself to decide whether to load it in Safari or in webview.

Now sometimes this is exactly what you want, which is fine; but some other times, especially if you have anchor links in your page, you want really to open only external links in Safari, and not internal ones. In that case you should check the URL.host property of your request.

I use that piece of code to check whether I have a hostname in the URL that is being parsed, or if it is embedded html:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    static NSString *regexp = @"^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9-]*[a-zA-Z0-9])[.])+([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$";
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regexp];

    if ([predicate evaluateWithObject:request.URL.host]) {
        [[UIApplication sharedApplication] openURL:request.URL];
        return NO; 
    } else {
        return YES; 
    }
}

You can of course adapt the regular expression to fit your needs.

Why I can't initialize static data members in class?

The C++ standard allows only static constant integral or enumeration types to be initialized inside the class. This is the reason a is allowed to be initialized while others are not.

Reference:
C++03 9.4.2 Static data members
§4

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

What are integral types?

C++03 3.9.1 Fundamental types
§7

Types bool, char, wchar_t, and the signed and unsigned integer types are collectively called integral types.43) A synonym for integral type is integer type.

Footnote:

⁴³⁾ Therefore, enumerations (7.2) are not integral; however, enumerations can be promoted to int, unsigned int, long, or unsigned long, as specified in 4.5.

Workaround:

You could use the enum trick to initialize an array inside your class definition.

class A 
{
    static const int a = 3;
    enum { arrsize = 2 };

    static const int c[arrsize] = { 1, 2 };

};

Why does the Standard does not allow this?

Bjarne explains this aptly here:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

Why are only static const integral types & enums allowed In-class Initialization?

The answer is hidden in Bjarne's quote read it closely,
"C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects."

Note that only static const integers can be treated as compile time constants. The compiler knows that the integer value will not change anytime and hence it can apply its own magic and apply optimizations, the compiler simply inlines such class members i.e, they are not stored in memory anymore, As the need of being stored in memory is removed, it gives such variables the exception to rule mentioned by Bjarne.

It is noteworthy to note here that even if static const integral values can have In-Class Initialization, taking address of such variables is not allowed. One can take the address of a static member if (and only if) it has an out-of-class definition.This further validates the reasoning above.

enums are allowed this because values of an enumerated type can be used where ints are expected.^{see citation above}

How does this change in C++11?

C++11 relaxes the restriction to certain extent.

C++11 9.4.2 Static data members
§3

If a static data member is of const literal type, its declaration in the class definition can specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. A static data member of literal type can be declared in the class definition with the constexpr specifier; if so, its declaration shall specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. [ Note: In both these cases, the member may appear in constant expressions. —end note ] The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

Also, C++11 will allow(§12.6.2.8) a non-static data member to be initialized where it is declared(in its class). This will mean much easy user semantics.

Note that these features have not yet been implemented in latest gcc 4.7, So you might still get compilation errors.

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

If you want to be able to call the func with or without the parameter you can create a second func of the same name which calls the other.

func test(firstThing: Int?) {
    if firstThing != nil {
        print(firstThing!)
    }
    print("done")
}

func test() {
    test(firstThing: nil)
}

now you can call a function named test without or without the parameter.

// both work
test()
test(firstThing: 5)

This tip shows how to use Logger in any java application. Logger needs to configure Formatter and Handler. There are many types of handlers and formatters present. In this example FileHandler is used to store all the log messages in a log file. And Simple formatter is used to format the log messages in human readable form.

package MyProject;

import java.io.IOException;
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;

public class MyLogger {

  public static void main(String[] args) {

    Logger logger = Logger.getLogger("MyLog");
    FileHandler fh;

    try {

      // This block configure the logger with handler and formatter
      fh = new FileHandler("c:\\MyLogFile.log", true);
      logger.addHandler(fh);
      logger.setLevel(Level.ALL);
      SimpleFormatter formatter = new SimpleFormatter();
      fh.setFormatter(formatter);

      // the following statement is used to log any messages   
      logger.log(Level.WARNING,"My first log");

    } catch (SecurityException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }

  }

Take any web application whether it is Gmail or Facebook or Instagram or any other web application, it's all about exchanging data or information between the end user and the application or the UI and the back end application. Even in Spring MVC world there are two ways to exchange data:

1. from the Controller to the UI, and
2. from the UI to the Controller.

What we are interested here is how the data is communicated from the UI to Controller. This can also be done in 2 ways:

1. Using an HTML Form
2. Using Query Parameters.

Using an HTML Form: Consider the below scenario,

When we submit the form data from the web browser, we can access that data in our Controller class as an object. When we submit an HTML form, the Spring Container does four things. It will,

1. first read all the data that is submitted that comes in the request using the request.getParameter method.
2. once it reads them, it will convert them into the appropriate Java type using integer.parseInt, double.parseDouble and all the other parse methods that are available based on the data type of the data.
3. once parsed, it will create a object of the model class that we created. For example, in this scenario, it is the user information that is being submitted and we create a class called User, which the Container will create an object of and it will set all the values that come in automatically into that object.
4. it will then handover that object by setting the values to the Controller.

To get this whole thing to work, we'll have to follow certain steps.

We first need to define a model class, like User, in which the number of fields should exactly match the number of fields in the HTML form. Also, the names that we use in the HTML form should match the names that we have in the Java class. These two are very important. Names should match, the number of fields in the form should match the number of fields in the class that we create. Once we do that, the Container will automatically read the data that comes in, creates an object of this model, sets the values and it hands it over to the Controller. To read those values inside the Controller, we use the @ModelAttribute annotation on the method parameters. When we create methods in the Controller, we are going to use the @ModelAttribute and add a parameter to it which will automatically have this object given by the Container.

Here is an example code for registering an user:

@RequestMapping(value = "registerUser", method = RequestMethod.POST)
public String registerUser(@ModelAttribute("user") User user, ModelMap model) {
    model.addAttribute("user", user);
    return "regResult";
}

Hope this diagrammatic explanation helped!

You need to call finish() from the UI thread, not a background thread. The way to do this is to declare a Handler and ask the Handler to run a Runnable on the UI thread. For example:

public class LoadingScreen extends Activity{
    private LoadingScreen loadingScreen;
    Intent i = new Intent(this, HomeScreen.class);
    Handler handler;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        handler = new Handler();
        setContentView(R.layout.loading);

        CountDownTimer timer = new CountDownTimer(10000, 1000) //10seceonds Timer
        {
             @Override
             public void onTick(long l) 
             {

             }

             @Override
             public void onFinish() 
             {
                 handler.post(new Runnable() {
                     public void run() {
                         loadingScreen.finishActivity(0);
                         startActivity(i);
                     }
                 });
             };
        }.start();
    }
}

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.

When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.

Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:

http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database

Update Collation of all fields in database on the fly

http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx

If you need to have different collation on two objects or can't change collations - you can still JOIN between them using COLLATE command, and choosing the collation you want for join.

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS 

or using default database collation:

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

Since the only missing example is the ANDROID example, I'll add it. This technique uses a custom AsyncTask that should be declared inside your Activity class.

private class UploadFile extends AsyncTask<Void, Integer, String> {
    @Override
    protected void onPreExecute() {
        // set a status bar or show a dialog to the user here
        super.onPreExecute();
    }

    @Override
    protected void onProgressUpdate(Integer... progress) {
        // progress[0] is the current status (e.g. 10%)
        // here you can update the user interface with the current status
    }

    @Override
    protected String doInBackground(Void... params) {
        return uploadFile();
    }

    private String uploadFile() {

        String responseString = null;
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("http://example.com/upload-file");

        try {
            AndroidMultiPartEntity ampEntity = new AndroidMultiPartEntity(
                new ProgressListener() {
                    @Override
                        public void transferred(long num) {
                            // this trigger the progressUpdate event
                            publishProgress((int) ((num / (float) totalSize) * 100));
                        }
            });

            File myFile = new File("/my/image/path/example.jpg");

            ampEntity.addPart("fileFieldName", new FileBody(myFile));

            totalSize = ampEntity.getContentLength();
            httpPost.setEntity(ampEntity);

            // Making server call
            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();

            int statusCode = httpResponse.getStatusLine().getStatusCode();
            if (statusCode == 200) {
                responseString = EntityUtils.toString(httpEntity);
            } else {
                responseString = "Error, http status: "
                        + statusCode;
            }

        } catch (Exception e) {
            responseString = e.getMessage();
        }
        return responseString;
    }

    @Override
    protected void onPostExecute(String result) {
        // if you want update the user interface with upload result
        super.onPostExecute(result);
    }

}

So, when you want to upload your file just call:

new UploadFile().execute();

Even if that's a 7 years old question, people new to R should consider using the data.table, package.

A data.table is a data.frame so all you can do for/to a data.frame you can also do. But many think are ORDERS of magnitude faster with data.table.

vec <- 1:10
library(data.table)
DT <- data.table(start=c(1,3,5,7), end=c(2,6,7,9))
DT[,new:=apply(DT,1,function(row) mean(vec[ row[1] : row[2] ] ))]

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

I wish I still had a link to the source that lead me in this direction, but this is the code that ended up working for me. By looking over the JavaDoc for X509TrustManager it looks like the way the TrustManagers work is by returning nothing on successful validation, otherwise throwing an exception. Thus, with a null implementation, it is treated as a successful validation. Then you remove all other implementations.

import javax.net.ssl.*;
import java.security.*;
import java.security.cert.X509Certificate;

public final class SSLUtil{

    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers(){
                    return null;
                }
                public void checkClientTrusted( X509Certificate[] certs, String authType ){}
                public void checkServerTrusted( X509Certificate[] certs, String authType ){}
            }
        };

    public  static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {
        // Install the all-trusting trust manager
        final SSLContext sc = SSLContext.getInstance("SSL");
        sc.init( null, UNQUESTIONING_TRUST_MANAGER, null );
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    public static void turnOnSslChecking() throws KeyManagementException, NoSuchAlgorithmException {
        // Return it to the initial state (discovered by reflection, now hardcoded)
        SSLContext.getInstance("SSL").init( null, null, null );
    }

    private SSLUtil(){
        throw new UnsupportedOperationException( "Do not instantiate libraries.");
    }
}

I ran into this just now with SQL Server 2014 SP1. The installer gave me the exact same problem and I followed suggestions from other answers to this question, but it got me nowhere.

In the end I figured out that I needed to download and install SQL Server 2014 first, and then apply SP1 to it. (doh)

Generic Solution

@Override
        public void onClick(View v) {
            tempDisableButton(v);
            //all the buttons view..
        }

public void tempDisableButton(View viewBtn) {
        final View button = viewBtn;

        button.setEnabled(false);
        button.postDelayed(new Runnable() {
            @Override
            public void run() {
                button.setEnabled(true);
            }
        }, 3000);
    }

Sadly it appears that the /deep/ selector is deprecated (at least in Chrome) https://www.chromestatus.com/features/6750456638341120

In short it appears there is (currently) no long term solution other than to somehow get your child component to style things dynamically.

You could pass a style object to your child and have it applied via:
<div [attr.style]="styleobject">

Or if you have a specific style you can use something like:
<div [style.background-color]="colorvar">

As Already mentioned we have two ways!

 Per screen (session) interactive setting

And it's done interactively! And take effect immediately!

CTRL + A followed by : And we type scrollback 1000000 And hit ENTER

You detach from the screen and come back! It will be always the same.

You open another new screen! And the value is reset again to default! So it's not a global setting!

 And the permanent default setting

Which is done by adding defscrollback 1000000 to .screenrc (in home)

defscrollback and not scrollback (def stand for default)

What you need to know is if the file is not created ! You create it !

> cd ~ && vim .screenrc

And you add defscrollback 1000000 to it!

Or in one command

> echo "defscrollback 1000000" >> .screenrc

(if not created already)

Taking effect

When you add the default to .screenrc! The already running screen at re-attach will not take effect! The .screenrc run at the screen creation! And it make sense! Just as with a normal console and shell launch!

And all the new created screens will have the set value!

Checking the screen effective buffer size

To check type CTRL + A followed by i

And The result will be as

Importantly the buffer size is the number after the + sign
(in the illustration i set it to 1 000 000)

Note too that when you change it interactively! The effect is immediate and take over the default value!

Scrolling

CTRL+ A followed by ESC (to enter the copy mode).

Then navigate with Up,Down or PgUp PgDown

And ESC again to quit that mode.

(Extra info: to copy hit ENTER to start selecting! Then ENTER again to copy! Simple and cool)

Now the buffer is bigger!

And that's sum it up for the important details!

The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:

=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60

If you want to do this using regex, you could simply use a non-capturing group, to get the word "world" and then grab everything after, like so

(?:world).*

The example string is tested here

It's an HtmlGenericControl so not sure what the recommended way to do this is, so you could also do:

testSpace.Attributes.Add("style", "text-align: center;");

or

testSpace.Attributes.Add("class", "centerIt");

or

testSpace.Attributes["style"] = "text-align: center;";

or

testSpace.Attributes["class"] = "centerIt";

Since Java 9 you have Objects#requireNonNullElse which does:

public static <T> T requireNonNullElse(T obj, T defaultObj) {
    return (obj != null) ? obj : requireNonNull(defaultObj, "defaultObj");
}

Your code would be

dinner = Objects.requireNonNullElse(cage.getChicken(), getFreeRangeChicken());

Which is 1 line and calls getChicken() only once, so both requirements are satisfied.

Note that the second argument cannot be null as well; this method forces non-nullness of the returned value.

Consider also the alternative Objects#requireNonNullElseGet:

public static <T> T requireNonNullElseGet(T obj, Supplier<? extends T> supplier)

which does not even evaluate the second argument if the first is not null, but does have the overhead of creating a Supplier.

Generally speaking, for boolean or bit data types, you would use 0 or 1 like so:

UPDATE tbl SET bitCol = 1 WHERE bitCol = 0

See also:

• Which MySQL data type to use for storing boolean values
• How do you create a yes/no boolean field in SQL server?

I use the "an index points between elements" method of thinking about it myself, but one way of describing it which sometimes helps others get it is this:

mylist[X:Y]

X is the index of the first element you want.
Y is the index of the first element you don't want.

Current Working Directory

To get the current working directory, you can use:

process.cwd()

However, be aware that some scripts, notably gulp, will change the current working directory with process.chdir().

Node Module Path

You can get the path of the current module with:

• __filename
• __dirname

Original Directory (where the command was initiated)

If you are running a script from the command line, and you want the original directory from which the script was run, regardless of what directory the script is currently operating in, you can use:

process.env.INIT_CWD

Original directory, when working with NPM scripts

It's sometimes desirable to run an NPM script in the current directory, rather than the root of the project.

This variable is available inside npm package scripts as:

$INIT_CWD.

You must be running a recent version of NPM. If this variable is not available, make sure NPM is up to date.

This will allow you access the current path in your package.json, e.g.:

scripts: {
  "customScript": "gulp customScript --path $INIT_CWD"
}

I could not install lombok.jar on my MacBook Pro because of the version of Java. I had to downgrade to Java 1.6 to install and then I reused Java 1.7 when the installation worked !

You can see the different JVM installed on your machine here : /System/Library/Java/JavaVirtualMachines

I tried all the answers and nothing really worked for me.

So I've created my own method that compares simple java objects without going deep into nested structures...

Method returns null if all fields match or string containing mismatch details.

Only properties that have a getter method are compared.

How to use

        assertNull(TestUtils.diff(obj1,obj2,ignore_field1, ignore_field2));

Sample output if there is a mismatch

Output shows property names and respective values of compared objects

alert_id(1:2), city(Moscow:London)

Code (Java 8 and above):

 public static String diff(Object x1, Object x2, String ... ignored) throws Exception{
        final StringBuilder response = new StringBuilder();
        for (Method m:Arrays.stream(x1.getClass().getMethods()).filter(m->m.getName().startsWith("get")
        && m.getParameterCount()==0).collect(toList())){

            final String field = m.getName().substring(3).toLowerCase();
            if (Arrays.stream(ignored).map(x->x.toLowerCase()).noneMatch(ignoredField->ignoredField.equals(field))){
                Object v1 = m.invoke(x1);
                Object v2 = m.invoke(x2);
                if ( (v1!=null && !v1.equals(v2)) || (v2!=null && !v2.equals(v1))){
                    response.append(field).append("(").append(v1).append(":").append(v2).append(")").append(", ");
                }
            }
        }
        return response.length()==0?null:response.substring(0,response.length()-2);
    }

If your index is less than the size of your list then it does exist, possibly with null value. If index is bigger then you may call ensureCapacity() to be able to use that index.

If you want to check if a value at your index is null or not, call get()

On Linux you can also use:

struct timeval timeout;
timeout.tv_sec  = 7;  // after 7 seconds connect() will timeout
timeout.tv_usec = 0;
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
connect(...)

Don't forget to clear SO_SNDTIMEO after connect() if you don't need it.

Here is a quite clean way to end edition with the Return Key or a touch in the background.

In Interface builder, embed your fields in a view of class UIFormView

What does this class :

• Automatically attach itself as fields delegate ( Either awaked from nib, or added manually )
• Keep a reference on the current edited field
• Dismiss the keyboard on return or touch in the background

Here is the code :

Interface

#import <UIKit/UIKit.h>

@interface UIFormView : UIView<UITextFieldDelegate>

-(BOOL)textFieldValueIsValid:(UITextField*)textField;
-(void)endEdit;

@end

Implementation

#import "UIFormView.h"

@implementation UIFormView
{
    UITextField* currentEditingTextField;
}

// Automatically register fields

-(void)addSubview:(UIView *)view
{
    [super addSubview:view];
    if ([view isKindOfClass:[UITextField class]]) {
        if ( ![(UITextField*)view delegate] ) [(UITextField*)view setDelegate:self];
    }
}

// UITextField Protocol

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    currentEditingTextField = textField;
}

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    currentEditingTextField = NULL;
}

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self endEdit];
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if ([self textFieldValueIsValid:textField]) {
        [self endEdit];
        return YES;
    } else {
        return NO;
    }
}

// Own functions

-(void)endEdit
{
    if (currentEditingTextField) {
        [currentEditingTextField endEditing:YES];
        currentEditingTextField = NULL;
    }
}


// Override this in your subclass to handle eventual values that may prevent validation.

-(BOOL)textFieldValueIsValid:(UITextField*)textField
{
    return YES;
}

@end

• By subclassing the form and overriding the textFieldValueIsValid: method, you can avoid end of edition if the value is not correct for the given field.

• If a field has a delegate set in Interface Builder, then the form does not change it. I don't see many reasons to set a different delegate to a particular field, but why not…

There is many ways to improve this form view class - Attach a delegate, do some layout, handle when the keyboards covers a field ( using the currentEditingTextField frame ), automatically start edition for the next field, ...

I personally keep it in my framework, and always subclass it to add features, it is quite often useful "as-is".

I hope it will helps. Cheers all

The another solution is service volume, You can define a service volume and mount host's PostgreSQL Data directory in that volume. Check out the given compose file for details.

version: '2'
services:
  db:   
    image: postgres:9.6.1
    volumes:
      - "/var/lib/postgresql/data:/var/lib/postgresql/data" 
    ports:
      - "5432:5432"

By doing this, another PostgreSQL service will run under container but uses same data directory which host PostgreSQL service is using.

function return_var_dump(){
    // It works like var_dump, but it returns a string instead of printing it.
    $args = func_get_args(); // For <5.3.0 support ...
    ob_start();
    call_user_func_array('var_dump', $args);
    return ob_get_clean();
}

 let error = NSError(domain:"", code:401, userInfo:[ NSLocalizedDescriptionKey: "Invaild UserName or Password"]) as Error
            self.showLoginError(error)

create an NSError object and typecast it to Error ,show it anywhere

private func showLoginError(_ error: Error?) {
    if let errorObj = error {
        UIAlertController.alert("Login Error", message: errorObj.localizedDescription).action("OK").presentOn(self)
    }
}

Make changes in the activity of your Manifest file like

android:windowSoftInputMode="adjustResize"

OR

Make changes in your onCreate() method in the activity class like

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

You can try a list comp

>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Another way is by using filter

>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Just to give you an another option, you could use https://sourceforge.net/projects/dd2vmdk/ as well. dd2vmdk is a *nix-based program that allows you to mount raw disk images (created by dd, dcfldd, dc3dd, ftk imager, etc) by taking the raw image, analyzing the master boot record (physical sector 0), and getting specific information that is need to create a vmdk file.

Personally, imo Qemu and the Zapotek's raw2vmdk tools are the best overall options to convert dd to vmdks.

Disclosure: I am the author of this project.

Run this command:

select @@version

There is a whole Section in the docs called 16.3.3.4 Mapping the request body with the @RequestBody annotation. And one called 16.3.3.5 Mapping the response body with the @ResponseBody annotation. I suggest you consult those sections. Also relevant: @RequestBody javadocs, @ResponseBody javadocs

Usage examples would be something like this:

Using a JavaScript-library like JQuery, you would post a JSON-Object like this:

{ "firstName" : "Elmer", "lastName" : "Fudd" }

Your controller method would look like this:

// controller
@ResponseBody @RequestMapping("/description")
public Description getDescription(@RequestBody UserStats stats){
    return new Description(stats.getFirstName() + " " + stats.getLastname() + " hates wacky wabbits");
}

// domain / value objects
public class UserStats{
    private String firstName;
    private String lastName;
    // + getters, setters
}
public class Description{
    private String description;
    // + getters, setters, constructor
}

Now if you have Jackson on your classpath (and have an <mvc:annotation-driven> setup), Spring would convert the incoming JSON to a UserStats object from the post body (because you added the @RequestBody annotation) and it would serialize the returned object to JSON (because you added the @ResponseBody annotation). So the Browser / Client would see this JSON result:

{ "description" : "Elmer Fudd hates wacky wabbits" }

See this previous answer of mine for a complete working example: https://stackoverflow.com/a/5908632/342852

Note: RequestBody / ResponseBody is of course not limited to JSON, both can handle multiple formats, including plain text and XML, but JSON is probably the most used format.

Update

Ever since Spring 4.x, you usually won't use @ResponseBody on method level, but rather @RestController on class level, with the same effect.

Here is a quote from the official Spring MVC documentation:

@RestController is a composed annotation that is itself meta-annotated with @Controller and @ResponseBody to indicate a controller whose every method inherits the type-level @ResponseBody annotation and, therefore, writes directly to the response body versus view resolution and rendering with an HTML template.

The underlying connection was closed: An unexpected error occurred on a receive.

This problem occurs when the server or another network device unexpectedly closes an existing Transmission Control Protocol (TCP) connection. This problem may occur when a time-out value on the server or on the network device is set too low. To resolve this problem, see resolutions A, D, E, F, and O. The problem can also occur if the server resets the connection unexpectedly, such as if an unhandled exception crashes the server process. Analyze the server logs to see if this may be the issue.

Resolution

To resolve this problem, make sure that you are using the most recent version of the .NET Framework.

Add a method to the class to override the GetWebRequest method. This change lets you access the HttpWebRequest object. If you are using Microsoft Visual C#, the new method must be similar to the following.

class MyTestService:TestService.TestService
{
    protected override WebRequest GetWebRequest(Uri uri)
    {
        HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);
        //Setting KeepAlive to false
        webRequest.KeepAlive = false;
        return webRequest;
    }
}

Excerpt from KB915599: You receive one or more error messages when you try to make an HTTP request in an application that is built on the .NET Framework 1.1 Service Pack 1.

The offending lines are the following:

MaxConnections=90
InitialConnections=80

You can increase the values to allow more connections.

Based on @Nick keets answer, here is a more complete example:

extension String: Error {} // Enables you to throw a string

extension String: LocalizedError { // Adds error.localizedDescription to Error instances
    public var errorDescription: String? { return self }
}

func test(color: NSColor) throws{
    if color == .red {
        throw "I don't like red"
    }else if color == .green {
        throw "I'm not into green"
    }else {
        throw "I like all other colors"
    }
}

do {
    try test(color: .green)
} catch let error where error.localizedDescription == "I don't like red"{
    Swift.print ("Error: \(error)") // "I don't like red"
}catch let error {
    Swift.print ("Other cases: Error: \(error.localizedDescription)") // I like all other colors
}

SQL Server drops and recreates the tables only if you:

• Add a new column
• Change the Allow Nulls setting for a column
• Change the column order in the table
• Change the column data type

Using ALTER is safer, as in case the metadata is lost while you re-create the table, your data will be lost.

I had the same problem. I wanted to 'bury' a folder at the bottom of the sort instead of bringing it to the top with the '!' character. Windows recognizes most special characters as just that, 'special', and therefore they ALL are sorted at the top.

However, if you think outside of the English characters, you will find a lot of luck. I used Character Map and the arial font, scrolled down past '~' and the others to the greek alphabet. Capitol Xi, ?, worked best for me, but I didn't check to see which was the actual 'lowest' in the sort.

Have a look to this wiki: LaTeX/Labels and Cross-referencing:

The hyperref package automatically includes the nameref package, and a similarly named command. It inserts text corresponding to the section name, for example:

\section{MyFirstSection}
\label{marker}
\section{MySecondSection} In section \nameref{marker} we defined...

I had the same ERROR message. tbrisker's solution did not work in my case. Instead this solved the issue:

$ python3 -m venv .env
