I Use

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
    <supportedRuntime version="v2.0.50727"/>
</startup>

It's works but just before de </configuration> tag otherwise the startup tag doesn't work properly

How to SQLITE in C#

I nearly used everything in that article to create the SQLite database for my own C# Application.

Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.

After you added the reference, refer to the dll from your code using the following line on top of your class:

using System.Data.SQLite;

You can find the dll's here:

SQLite DLL's

You can find the NuGet way here:

NuGet

Up next is the create script. Creating a database file:

SQLiteConnection.CreateFile("MyDatabase.sqlite");

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();

string sql = "create table highscores (name varchar(20), score int)";

SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

sql = "insert into highscores (name, score) values ('Me', 9001)";

command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

m_dbConnection.Close();

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.

Example on how to use transactions:

 using (TransactionScope tran = new TransactionScope())
 {
     //Insert create script here.

     //Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
     tran.Complete();
 }

Have you tried .editorconfig? You can create this file in the root of your project and configure indentation for different file types. Your code will be automatically formatted. Here's the example:

# top-most EditorConfig file
root = true

# matches all files
[*]
indent_style = tab
indent_size = 4

# only json
[*.json]
indent_style = space
indent_size = 2

For Angular 9.0 and above, update the "schematics":{} object in angular.json file like this:

"schematics": {
  "@schematics/angular:component": {
    "style": "scss"
  }
}

This code also working .

#!/bin/bash
FILE=$1
if [ -f $FILE ]; then
 echo "File '$FILE' Exists"
else
 echo "The File '$FILE' Does Not Exist"
fi

why dont you add a "source" column to each of the queries with a static value like

select 'source 1' as Source, column1, column2...
from table1

UNION ALL

select 'source 2' as Source, column1, column2...
from table2

The easiest way I've found to create postscripts is the following, using the setEPS() command:

setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()

If Android Studio directly opening your project instead of setup window, then just close the windows of all projects. Now you will able to see the startup window. If SDK is missing then it will provide option to download SDK and other required tools.

It works for me.

This is a REALLY old thread, but it was still the first thing to pop up when I googled the issue. So I just wanted to add this:

InputStream inputStream = conn.getInputStream();
int length = inputStream.available();

Worked for me. And MUCH simpler than the other answers here.

Warning This solution does not provide reliable results regarding the total size of a stream. Except from the JavaDoc:

Note that while some implementations of {@code InputStream} will return * the total number of bytes in the stream, many will not.

It would most likely process them sequentially (why not just test it). But you can also do this:

1. make a file called curlrequests.sh

2. put it in a file like thus:

   curl http://example.com/?update_=1
   curl http://example.com/?update_=3
   curl http://example.com/?update_=234
   curl http://example.com/?update_=65
   

3. save the file and make it executable with chmod:

   chmod +x curlrequests.sh
   

4. run your file:

   ./curlrequests.sh
   

or

   /path/to/file/curlrequests.sh

As a side note, you can chain requests with &&, like this:

   curl http://example.com/?update_=1 && curl http://example.com/?update_=2 && curl http://example.com?update_=3`

And execute in parallel using &:

   curl http://example.com/?update_=1 & curl http://example.com/?update_=2 & curl http://example.com/?update_=3

(class/ID):after {
content:none;
}

Always works for me class or ID can be for a div or even body causing the white space.

Slight modification to what was stated above. My Json format, which validates was

{
    mycollection:{[
           {   
               property0:value,
               property1:value,
             },
             {   
               property0:value,
               property1:value,
             }
           ]

         }
       }

Using AlexDev's response, I did this Looping each child, creating reader from it

 public partial class myModel
{
    public static List<myModel> FromJson(string json) => JsonConvert.DeserializeObject<myModelList>(json, Converter.Settings).model;
}

 public class myModelList {
    [JsonConverter(typeof(myModelConverter))]
    public List<myModel> model { get; set; }

}

class myModelConverter : JsonConverter
{
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        var token = JToken.Load(reader);
        var list = Activator.CreateInstance(objectType) as System.Collections.IList;
        var itemType = objectType.GenericTypeArguments[0];
        foreach (var child in token.Children())  //mod here
        {
            var newObject = Activator.CreateInstance(itemType);
            serializer.Populate(child.CreateReader(), newObject); //mod here
            list.Add(newObject);
        }
        return list;
    }

    public override bool CanConvert(Type objectType)
    {
        return objectType.IsGenericType && (objectType.GetGenericTypeDefinition() == typeof(List<>));
    }
    public override bool CanWrite => false;
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) => throw new NotImplementedException();

}

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

It's used to load modules. Let's use a simple example.

In file circle_object.js:

var Circle = function (radius) {
    this.radius = radius
}
Circle.PI = 3.14

Circle.prototype = {
    area: function () {
        return Circle.PI * this.radius * this.radius;
    }
}

We can use this via require, like:

node> require('circle_object')
{}
node> Circle
{ [Function] PI: 3.14 }
node> var c = new Circle(3)
{ radius: 3 }
node> c.area()

The require() method is used to load and cache JavaScript modules. So, if you want to load a local, relative JavaScript module into a Node.js application, you can simply use the require() method.

Example:

var yourModule = require( "your_module_name" ); //.js file extension is optional

Instead of formatting namenode, may be you can use the below command to restart the namenode. It worked for me:

sudo service hadoop-master restart

2. hadoop dfsadmin -safemode leave

This code example that follows shows a basic UILabel configuration.

let lbl = UILabel(frame: CGRectMake(0, 0, 300, 200))
lbl.text = "yourString"

// Enum type, two variations:
lbl.textAlignment = NSTextAlignment.Right
lbl.textAlignment = .Right

lbl.textColor = UIColor.red
lbl.shadowColor = UIColor.black
lbl.font = UIFont(name: "HelveticaNeue", size: CGFloat(22))
self.view.addSubview(lbl)

s='foo bar baz'
a=( $s )
echo ${a[0]}
echo ${a[1]}
...

Use this one:

ArrayList<String> x = new ArrayList(Arrays.asList("abc", "mno"));

$rootScope.$broadcast is a convenient way to raise a "global" event which all child scopes can listen for. You only need to use $rootScope to broadcast the message, since all the descendant scopes can listen for it.

The root scope broadcasts the event:

$rootScope.$broadcast("myEvent");

Any child Scope can listen for the event:

$scope.$on("myEvent",function () {console.log('my event occurred');} );

Why we use $rootScope.$broadcast? You can use $watch to listen for variable changes and execute functions when the variable state changes. However, in some cases, you simply want to raise an event that other parts of the application can listen for, regardless of any change in scope variable state. This is when $broadcast is helpful.

• name identifies form fields* ; so they can be shared by controls that stand to represent multiple possibles values for such a field (radio buttons, checkboxes). They will be submitted as keys for form values.
• id identifies DOM elements ; so they can be targeted by CSS or Javascript.

* names also used to identify local anchors, but this is deprecated and 'id' is a preferred way to do so nowadays.

I have done some testing and using CSS3 to redefine the scrollbars works and you get to keep your Overflow:scroll; or Overflow:auto

I ended up with something like this...

::-webkit-scrollbar {
    width: 15px;
    height: 15px;
    border-bottom: 1px solid #eee; 
    border-top: 1px solid #eee;
}
::-webkit-scrollbar-thumb {
    border-radius: 8px;
    background-color: #C3C3C3;
    border: 2px solid #eee;
}

::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.2); 
} 

The only down side which I have not yet been able to figure out is how to interact with the scrollbars on iProducts but you can interact with the content to scroll it

Exactly how to do this depends on the version of Jackson that you're using. This changed around version 1.9, before that, you could do this by adding @JsonIgnore to the getter.

Which you've tried:

Add @JsonIgnore on the getter method only

Do this, and also add a specific @JsonProperty annotation for your JSON "password" field name to the setter method for the password on your object.

More recent versions of Jackson have added READ_ONLY and WRITE_ONLY annotation arguments for JsonProperty. So you could also do something like:

@JsonProperty(access = Access.WRITE_ONLY)
private String password;

Docs can be found here.

The API Demos in the Android SDK have an example that does just that.

It's under DIALOG_TEXT_ENTRY. They have a layout, inflate it with a LayoutInflater, and use that as the View.

EDIT: What I had linked to in my original answer is stale. Here is a mirror.

EOF is not a character. It can't be: A (binary) file can contain any character. Assume you have a file with ever-increasing bytes, going 0 1 2 3 ... 255 and once again 0 1 ... 255, for a total of 512 bytes. Whichever one of those 256 possible bytes you deem EOF, the file will be cut short.

That's why getchar() et al. return an int. The range of possible return values are those that a char can have, plus a genuine int value EOF (defined in stdio.h). That's also why converting the return value to a char before checking for EOF will not work.

Note that some protocols have "EOF" "characters." ASCII has "End of Text", "End of Transmission", "End of Transmission Block" and "End of Medium". Other answers have mentioned old OS'es. I myself input ^D on Linux and ^Z on Windows consoles to stop giving programs input. (But files read via pipes can have ^D and ^Z characters anywhere and only signal EOF when they run out of bytes.) C strings are terminated with the '\0' character, but that also means they cannot contain the character '\0'. That's why all C non-string data functions work using a char array (to contain the data) and a size_t (to know where the data ends).

Edit: The C99 standard §7.19.1.3 states:

The macros are [...]
EOF
which expands to an integer constant expression, with type int and a negative value, that is returned by several functions to indicate end-of-?le, that is, no more input from a stream;

I decided to compact everything I learned into one file. There's a lot to take in here especially compared to before RC5. Note that this source file includes the AppModule and AppComponent.

If you also want to keep hash and get parameter, you can do something like this (fill redirectMap at filter init):

String uri = request.getRequestURI();

String[] uriParts = uri.split("[#?]");
String path = uriParts[0];
String rest = uri.substring(uriParts[0].length());

if(redirectMap.containsKey(path)) {
    response.sendRedirect(redirectMap.get(path) + rest);
} else {
    chain.doFilter(request, response);
}

Having this issue with Ruby 2.3.4:

I solved it uninstalling OpenSSL and reinstalling it. I ran:

brew uninstall --ignore-dependencies openssl

then

brew install openssl

It did the job.

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

A great way of handling this is with regular expressions.

string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");

This will replace any of the 3 legal types of newline with the html tag.

If you wish to test that a variable is bound or unbound, this works well, even after you've turned on the nounset option:

set -o noun set

if printenv variableName >/dev/null; then
    # variable is bound to a value
else
    # variable is unbound
fi

You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).

By default, imshow sets the aspect of the plot to 1, as this is often what people want for image data.

In your case, you can do something like:

import matplotlib.pyplot as plt
import numpy as np

grid = np.random.random((10,10))

fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))

ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')

ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')

ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')

plt.tight_layout()
plt.show()

Why not use the Date object like this?

let getTime = (milli) => {
  let time = new Date(milli);
  let hours = time.getUTCHours();
  let minutes = time.getUTCMinutes();
  let seconds = time.getUTCSeconds();
  let milliseconds = time.getUTCMilliseconds();
  return hours + ":" + minutes + ":" + seconds + ":" + milliseconds;
}

The EOF pattern needs a prime read to 'bootstrap' the EOF checking process. Consider the empty file will not initially have its EOF set until the first read. The prime read will catch the EOF in this instance and properly skip the loop completely.

What you need to remember here is that you don't get the EOF until the first attempt to read past the available data of the file. Reading the exact amount of data will not flag the EOF.

I should point out if the file was empty your given code would have printed since the EOF will have prevented a value from being set to x on entry into the loop.

• 0

So add a prime read and move the loop's read to the end:

int x;

iFile >> x; // prime read here
while (!iFile.eof()) {
    cerr << x << endl;
    iFile >> x;
}

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete()

To delete it from an instance:

instance1 = SomeModel.objects.get(id=id)
instance1.delete()

// don't use same name

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

I cant comment, so just beware, that if your column supports NULL values, OLD.x<>NEW.x isnt enough, because

SELECT IF(1<>NULL,1,0)

returns 0 as same as

NULL<>NULL 1<>NULL 0<>NULL 'AAA'<>NULL

So it will not track changes FROM and TO NULL

The correct way in this scenario is

I ran into this issue running Android Studio 1.4. In the Android Virtual Device (AVD) Manager, I had checked the 'Use Host GPU' box, thinking this would give me some sort of boost in the emulator's speed.
Android Studio will let you choose a device that's configured that way, and it will show you the command it used to start the virtual device:

but for some reason, it doesn't warn you that the program crashed, and it doesn't show you the stderr message that you would see had you run it from the command line yourself:

When I ran it from Android Studio, I didn't see the dialog box in the screenshot above, though it shows up just fine when you run the command from the command line, so I just sat there patiently for a few minutes while nothing happened.
As pointed out elsewhere, the drivers needed for the Use Host GPU option are not yet available. Reading through that post, it appears that this setting can be used with some Intel CPUs but not the ARM chip I chose (see CPU/ABI setting below).

My solution was to just uncheck the "Use Host GPU" box which is near the bottom of the window opened through the 'edit' option after choosing the virtual device in the Android Virtual Devices tab in the AVD Manager. You can get to the AVD manager directly in Windows at
%ANDROID_HOME%\AVD Manager.exe
where in my Windows 8 install, %ANDROID_HOME% resolved to
c:\users\myusername\AppData\Local\Android\Sdk

I don't have it running on Linux at the moment, but I'd assume it's in a similar path there, i.e.:
${ANDROID_HOME}/

After unchecking the 'Use Host GPU' box, I opted to check the 'Snapshot' box next to it (as I understand, that stores a copy of the already-built vm so it doesn't need to get rebuilt every time, which should save some startup time for future instances). Here are the full settings I used:

Cracked it. Just @Damnum steps and then follow the path to run xcode. Bad way but running like a charm.

Double click to /Applications/Xcode102.app/Contents/MacOS/Xcode

Before importing the project, it should be converted into eclipse project mvn eclipse: eclipse Then i found the following error. An internal error occurred during: "Importing Maven projects".Unsupported IClasspathEntry kind=4

Where is the value kind = "var" that M2E does not recognize and therefore throws the error.

Now type this. mvn eclipse: clean

Now refresh the project in eclipse or re-import.

Since i have have just one element in my Set the order is not important So I can access to the first element like this :

${ attachments.iterator().next().id }

.phtml was the standard file extension for PHP 2 programs. .php3 took over for PHP 3. When PHP 4 came out they switched to a straight .php.

The older file extensions are still sometimes used, but aren't so common.

Edit: atp's answer below is better. Please use that one!

You might have an easier time, if you're looking for a specific list of files, putting them directly on the command line instead:

# rsync -avP -e ssh `cat deploy/rsync_include.txt` [email protected]:/var/www/

This is assuming, however, that your list isn't so long that the command line length will be a problem and that the rsync_include.txt file contains just real paths (i.e. no comments, and no regexps).

For Windows users: Try deleting files: java.exe, javaw.exe and javaws.exe from Windows\System32

My issue was the java version 1.7 installed.

Create a new class in Android kotlin with the name DecimalDigitsInputFilter

class DecimalDigitsInputFilter(digitsBeforeDecimal: Int, digitsAfterDecimal: Int) : InputFilter {

    var mPattern: Pattern = Pattern.compile("[0-9]{0,$digitsBeforeDecimal}+((\\.[0-9]{0,$digitsAfterDecimal})?)||(\\.)?")

    override fun filter(
        source: CharSequence?,
        start: Int,
        end: Int,
        dest: Spanned?,
        dstart: Int,
        dend: Int
    ): CharSequence? {
        val matcher: Matcher = mPattern.matcher(
            dest?.subSequence(0, dstart).toString() + source?.subSequence(
                start,
                end
            ).toString() + dest?.subSequence(dend, dest.length).toString()
        )
        if (!matcher.matches())
            return ""
        else
            return null
    }
}

Call this class with the following line

 et_buy_amount.filters = (arrayOf<InputFilter>(DecimalDigitsInputFilter(8,2)))

there are too many answers for the same but it will allow you to enter 8 digit before decimal and 2 digits after decimal

other answers are accepting only 8 digits

With CSS positioning, you can place an element exactly where you want it on your page.

When you are going to use CSS positioning, the first thing you need to do is use the CSS property position to tell the browser if you're going to use absolute or relative positioning.

Both Positions are having different features. In CSS Once you set Position then you can able to use top, right, bottom, left attributes.

Absolute Position

An absolute position element is positioned relative to the first parent element that has a position other than static.

Relative Position

A relative positioned element is positioned relative to its normal position.

To position an element relatively, the property position is set as relative. The difference between absolute and relative positioning is how the position is being calculated.

Choose target device: USB device

(open image in new tab for bigger)

This should work as well

text = 'the car? was big and* red!'

newtext = re.sub( '[^a-z0-9]', ' ', text)

print(newtext)

the car was big and red

IMHO you could just send the JSON encoded (ie. encodeURIComponent) in the URL, this way you do not violate the HTTP specs and get your JSON to the server.

I resolved that situation in this way. I created a util method that return a object extracted from request body, using the readValue method of ObjectMapper that is capable of receiving a Reader.

public static <T> T getBody(ResourceRequest request, Class<T> class) {
    T objectFromBody = null;
    try {
        ObjectMapper objectMapper = new ObjectMapper();
        HttpServletRequest httpServletRequest = PortalUtil.getHttpServletRequest(request);
        objectFromBody = objectMapper.readValue(httpServletRequest.getReader(), class);
    } catch (IOException ex) {
        log.error("Error message", ex);
    }
    return objectFromBody;
}

declare @dateOfBirth date select @dateOfBirth = '2000-01-01'

SELECT datediff(YEAR,@dateOfBirth,getdate()) as Age

If you need to show short date and time (11/08/2018 03:23 a.m.) you can do it like this:

{{your_date_field|date:"SHORT_DATE_FORMAT"}} {{your_date_field|time:"h:i a"}}

Details for this tag here and more about dates according to the given format here

Example:

<small class="text-muted">Last updated: {{your_date_field|date:"SHORT_DATE_FORMAT"}} {{your_date_field|time:"h:i a"}}</small>

One of the way I did and worked for all of the cases is using Guava Library and regex in combination.

public static String getDomainNameWithGuava(String url) throws MalformedURLException, 
  URISyntaxException {
    String host =new URL(url).getHost();
    String domainName="";
    try{
        domainName = InternetDomainName.from(host).topPrivateDomain().toString();
    }catch (IllegalStateException | IllegalArgumentException e){
        domainName= getDomain(url,true);
    }
    return domainName;
}

getDomain() can be any common method with regex.

You might be better off if you just don't use nested classes. If you must nest, try this:

x = 1
class OuterClass:
    outer_var = x
    class InnerClass:
        inner_var = x

Or declare both classes before nesting them:

class OuterClass:
    outer_var = 1

class InnerClass:
    inner_var = OuterClass.outer_var

OuterClass.InnerClass = InnerClass

(After this you can del InnerClass if you need to.)

The Maven profile and the Spring profile are two completely different things. Your pom.xml defines spring.profiles.active variable which is available in the build process, but not at runtime. That is why only the default profile is activated.

How to bind Maven profile with Spring?

You need to pass the build variable to your application so that it is available when it is started.

1. Define a placeholder in your application.properties:

   [email protected]@
   

   The @spring.profiles.active@ variable must match the declared property from the Maven profile.

2. Enable resource filtering in you pom.xml:

   <build>
       <resources>
           <resource>
               <directory>src/main/resources</directory>
               <filtering>true</filtering>
           </resource>
       </resources>
       …
   </build>
   

   When the build is executed, all files in the src/main/resources directory will be processed by Maven and the placeholder in your application.properties will be replaced with the variable you defined in your Maven profile.

For more details you can go to my post where I described this use case.

I guess the verdict is i cannot programmatically uniquely identify a computer which is visiting my web site.

I have the following question. When i use a machine which has never visited my online banking web site i get asked for additional authentification. then, if i go back a second time to the online banking site i dont get asked the additional authentification. reading the answers to my question i decided it must be a cookie involved. therefore, i deleted all cookies in IE and relogged onto my online banking site fully expecting to be asked the authentification questions again. to my surprise i was not asked. doesnt this lead one to believe the bank is doing some kind of pc tagging which doesnt involve cookies?

further, after much googling today i found the following company who claims to sell a solution which does uniquely identify machines which visit a web site. http://www.the41.com/products.asp.

i appreciate all the good information if you could clarify further this conflicting information i found i would greatly appreciate it.

The default shortcut key is Ctrl-Alt-C.

WordPress have the function get_metadata this get all meta of object (Post, term, user...)

Just use

get_metadata( 'post', 15 );

    if (!$_FILES['image']['size'][0] == 0){ //}

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Google Places API also provides REST api including Places Autocomplete. https://developers.google.com/places/documentation/autocomplete

But the data retrieve from the service must use for a map.

The first push should be a:

git push -u origin branchname

That would make sure:

• your local branch has a remote tracking branch of the same name referring an upstream branch in your remote repo 'origin',
• this is compliant with the default push policy 'simple'

Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.

try this:

var c=document.getElementById("alpha");
var d=c.toDataURL("image/png");
var w=window.open('about:blank','image from canvas');
w.document.write("<img src='"+d+"' alt='from canvas'/>");

This shows image from canvas on new page, but if you have open popup in new tab setting it shows about:blank in address bar.

EDIT:- though window.open("<img src='"+ c.toDataURL('image/png') +"'/>") does not work in FF or Chrome, following works though rendering is somewhat different from what is shown on canvas, I think transparency is the issue:

window.open(c.toDataURL('image/png'));

You do NOT need openssl or makecert or any of that. You also don't need the personal key given to you by your CA. I can almost guarantee that the problem is that you expect to be able to use the key and cer files provided by your CA but they aren't based on "the IIS way". I'm so tired of seeing bad and difficult info out here that I decided to blog the subject and the solution. When you realize what's going on and see how easy it is, you will want to hug me :)

SSL Certs for IIS with PFX once and for all - SSL and IIS Explained - http://rainabba.blogspot.com/2014/03/ssl-certs-for-iis-with-pfx-once-and-for.html

Use IIS "Server Certificates" UI to "Generate Certificate Request" (the details of this request are out of the scope of this article but those details are critical). This will give you a CSR prepped for IIS. You then give that CSR to your CA and ask for a certificate. Then you take the CER/CRT file they give you, go back to IIS, "Complete Certificate Request" in the same place you generated the request. It may ask for a .CER and you might have a .CRT. They are the same thing. Just change the extension or use the . extension drop-down to select your .CRT. Now provide a proper "friendly name" (*.yourdomain.com, yourdomain.com, foo.yourdomain.com, etc..) THIS IS IMPORTANT! This MUST match what you setup the CSR for and what your CA provided you. If you asked for a wildcard, your CA must have approved and generated a wildcard and you must use the same. If your CSR was generated for foo.yourdomain.com, you MUST provide the same at this step.

It's getElementsByName() and getElementsByTagName() - note the "s" in "Elements", indicating that both functions return a list of elements, i.e., a NodeList, which you will access like an array. Note that the second function ends with "TagName" not "Tag".

Even if the function only returns one element it will still be in a NodeList of length one. So:

var els = document.getElementsByName('frmMain');
// els.length will be the number of elements returned
// els[0] will be the first element returned
// els[1] the second, etc.

Assuming your form is the first (or only) form on the page you can do this:

document.getElementsByName('frmMain')[0].elements
document.getElementsByTagName('table')[0].elements

Try using firefox 46.0.1. It best matches with Selenium 2.53

https://ftp.mozilla.org/pub/firefox/releases/46.0.1/win64/en-US/

"location" : null // this is not really an array it's a null object
"location" : []   // this is an empty array

It looks like this API returns null when there is no location defined - instead of returning an empty array, not too unusual really - but they should tell you if they're going to do this.

For large datasets, it is memory efficient to read only selected rows via the skiprows parameter.

Example

pred = lambda x: x not in [1, 3]
pd.read_csv("data.csv", skiprows=pred, index_col=0, names=...)

This will now return a DataFrame from a file that skips all rows except 1 and 3.

Details

From the docs:

skiprows : list-like or integer or callable, default None

...

If callable, the callable function will be evaluated against the row indices, returning True if the row should be skipped and False otherwise. An example of a valid callable argument would be lambda x: x in [0, 2]

This feature works in version pandas 0.20.0+. See also the corresponding issue and a related post.

I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account

In my RegisterActivity, use an AsyncTask

//AsyncTask
private class Register extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {..}

    @Override
    protected String doInBackground(String... params) {
        new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
        responseMensaje = StaticValues.mensaje ;
        mensajeCodigo = StaticValues.mensajeCodigo;
        return String.valueOf(StaticValues.code);
    }

    @Override
    protected void onPostExecute(String codeResult) {..}

And in my Register.java class is where use Retrofit with synchronous call

import android.util.Log;

        // add another part within the multipart request
        RequestBody requestEmail =
                RequestBody.create(
                        MediaType.parse("multipart/form-data"), email);

            // MultipartBody.Part is used to send also the actual file name
            imagenPerfil = MultipartBody.Part.createFormData("imagenPerfil", file.getName(), requestFile);
        }

        Log.i("Register","mensajeCodigo "+StaticValues.mensaje);
    }
    catch (Exception e){
        e.printStackTrace();

}

In the interface of RegisterService

public interface RegisterService {

                                @Part("nombre") RequestBody nombre
);
}

For the Utilities parse ofr InputStream response

public class Utilities {
public static String mensajeCodigoDeLaRespuestaJSON(InputStream inputStream){
    String mensajeCodigo = null;
    try {
        BufferedReader reader = new BufferedReader(
                new InputStreamReader(
                    inputStream, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            sb.append(line).append("\n");
        }
        inputStream.close();
        mensajeCodigo = sb.toString();
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }
    return mensajeCodigo;
}
}

It is kind of screwy, but in a pinch you can use sed or awk to make small edits or remove text. Be careful with your regex targets of course and be aware that you're likely root on your container and might have to re-adjust permissions.

For example, removing a full line that contains text matching a regex:

awk '!/targetText/' file.txt > temp && mv temp file.txt

(More)

var n_numTabs = $("#superpics div").size();

or

var n_numTabs = $("#superpics div").length;

As was already said, both return the same result.
But the size() function is more jQuery "P.C".
I had a similar problem with my page.
For now on, just omit the > and it should work fine.

What you're trying to accomplish is called Reverse DNS lookup.

socket.gethostbyaddr("IP") 
# => (hostname, alias-list, IP)

http://docs.python.org/library/socket.html?highlight=gethostbyaddr#socket.gethostbyaddr

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.

As the previous answers exhaustively covered the theory behind the value categories, there is just another thing I'd like to add: you can actually play with it and test it.

For some hands-on experimentation with the value categories, you can make use of the decltype specifier. Its behavior explicitly distinguishes between the three primary value categories (xvalue, lvalue, and prvalue).

Using the preprocessor saves us some typing ...

Primary categories:

#define IS_XVALUE(X) std::is_rvalue_reference<decltype((X))>::value
#define IS_LVALUE(X) std::is_lvalue_reference<decltype((X))>::value
#define IS_PRVALUE(X) !std::is_reference<decltype((X))>::value

Mixed categories:

#define IS_GLVALUE(X) (IS_LVALUE(X) || IS_XVALUE(X))
#define IS_RVALUE(X) (IS_PRVALUE(X) || IS_XVALUE(X))

Now we can reproduce (almost) all the examples from cppreference on value category.

Here are some examples with C++17 (for terse static_assert):

void doesNothing(){}
struct S
{
    int x{0};
};
int x = 1;
int y = 2;
S s;

static_assert(IS_LVALUE(x));
static_assert(IS_LVALUE(x+=y));
static_assert(IS_LVALUE("Hello world!"));
static_assert(IS_LVALUE(++x));

static_assert(IS_PRVALUE(1));
static_assert(IS_PRVALUE(x++));
static_assert(IS_PRVALUE(static_cast<double>(x)));
static_assert(IS_PRVALUE(std::string{}));
static_assert(IS_PRVALUE(throw std::exception()));
static_assert(IS_PRVALUE(doesNothing()));

static_assert(IS_XVALUE(std::move(s)));
// The next one doesn't work in gcc 8.2 but in gcc 9.1. Clang 7.0.0 and msvc 19.16 are doing fine.
static_assert(IS_XVALUE(S().x)); 

The mixed categories are kind of boring once you figured out the primary category.

For some more examples (and experimentation), check out the following link on compiler explorer. Don't bother reading the assembly, though. I added a lot of compilers just to make sure it works across all the common compilers.

IE11 uses an older version of the Grid specification.

The properties you are using don't exist in the older grid spec. Using prefixes makes no difference.

Here are three problems I see right off the bat.

repeat()

The repeat() function doesn't exist in the older spec, so it isn't supported by IE11.

You need to use the correct syntax, which is covered in another answer to this post, or declare all row and column lengths.

Instead of:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: repeat( 4, 1fr );
      grid-template-columns: repeat( 4, 1fr );
  -ms-grid-rows: repeat( 4, 270px );
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Use:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: 1fr 1fr 1fr 1fr;             /* adjusted */
      grid-template-columns:  repeat( 4, 1fr );
  -ms-grid-rows: 270px 270px 270px 270px;        /* adjusted */
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-repeating-columns-and-rows

span

The span keyword doesn't exist in the older spec, so it isn't supported by IE11. You'll have to use the equivalent properties for these browsers.

Instead of:

.grid .grid-item.height-2x {
  -ms-grid-row: span 2;
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column: span 2;
      grid-column: span 2;
}

Use:

.grid .grid-item.height-2x {
  -ms-grid-row-span: 2;          /* adjusted */
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column-span: 2;       /* adjusted */
      grid-column: span 2;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-row-span-and-grid-column-span

grid-gap

The grid-gap property, as well as its long-hand forms grid-column-gap and grid-row-gap, don't exist in the older spec, so they aren't supported by IE11. You'll have to find another way to separate the boxes. I haven't read the entire older spec, so there may be a method. Otherwise, try margins.

grid item auto placement

There was some discussion in the old spec about grid item auto placement, but the feature was never implemented in IE11. (Auto placement of grid items is now standard in current browsers).

So unless you specifically define the placement of grid items, they will stack in cell 1,1.

Use the -ms-grid-row and -ms-grid-column properties.

The API Doc are very clear on this.

All generators implement the interface org.hibernate.id.IdentifierGenerator. This is a very simple interface. Some applications can choose to provide their own specialized implementations, however, Hibernate provides a range of built-in implementations. The shortcut names for the built-in generators are as follows:

increment

generates identifiers of type long, short or int that are unique only when no other process is inserting data into the same table. Do not use in a cluster.

identity

supports identity columns in DB2, MySQL, MS SQL Server, Sybase and HypersonicSQL. The returned identifier is of type long, short or int.

sequence

uses a sequence in DB2, PostgreSQL, Oracle, SAP DB, McKoi or a generator in Interbase. The returned identifier is of type long, short or int

hilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a table and column (by default hibernate_unique_key and next_hi respectively) as a source of hi values. The hi/lo algorithm generates identifiers that are unique only for a particular database.

seqhilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a named database sequence.

uuid

uses a 128-bit UUID algorithm to generate identifiers of type string that are unique within a network (the IP address is used). The UUID is encoded as a string of 32 hexadecimal digits in length.

guid

uses a database-generated GUID string on MS SQL Server and MySQL.

native

selects identity, sequence or hilo depending upon the capabilities of the underlying database.

assigned

lets the application assign an identifier to the object before save() is called. This is the default strategy if no element is specified.

select

retrieves a primary key, assigned by a database trigger, by selecting the row by some unique key and retrieving the primary key value.

foreign

uses the identifier of another associated object. It is usually used in conjunction with a primary key association.

sequence-identity

a specialized sequence generation strategy that utilizes a database sequence for the actual value generation, but combines this with JDBC3 getGeneratedKeys to return the generated identifier value as part of the insert statement execution. This strategy is only supported on Oracle 10g drivers targeted for JDK 1.4. Comments on these insert statements are disabled due to a bug in the Oracle drivers.

If you are building a simple application with not much concurrent users, you can go for increment, identity, hilo etc.. These are simple to configure and did not need much coding inside the db.

You should choose sequence or guid depending on your database. These are safe and better because the id generation will happen inside the database.

Update: Recently we had an an issue with idendity where primitive type (int) this was fixed by using warapper type (Integer) instead.

I've assumed a named JSONArray is a JSONObject and accessed the data from the server to populate an Android GridView. For what it is worth my method is:

private String[] fillTable( JSONObject jsonObject ) {
   String[] dummyData = new String[] {"1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7", };
  if( jsonObject != null ) {
      ArrayList<String> data = new ArrayList<String>();
      try {
          // jsonArray looks like { "everything" : [{}, {},] }
          JSONArray jsonArray = jsonObject.getJSONArray( "everything" );
          int number = jsonArray.length(); //How many rows have got from the database?
          Log.i( Constants.INFORMATION, "Number of ows returned:  " + Integer.toString( number ) );
                  // Array elements look like this
          //{"success":1,"error":0,"name":"English One","owner":"Tutor","description":"Initial Alert","posted":"2013-08-09 15:35:40"}
          for( int element = 0; element < number; element++ ) { //visit each element
             JSONObject jsonObject_local = jsonArray.getJSONObject( element );
             //  Overkill on the error/success checking
             Log.e("JSON SUCCESS", Integer.toString( jsonObject_local.getInt(Constants.KEY_SUCCESS) ) );
             Log.e("JSON ERROR", Integer.toString( jsonObject_local.getInt(Constants.KEY_ERROR) ) );
                if ( jsonObject_local.getInt( Constants.KEY_SUCCESS) == Constants.JSON_SUCCESS ) {
                   String name = jsonObject_local.getString( Constants.KEY_NAME );
                   data.add( name );
                   String owner = jsonObject_local.getString( Constants.KEY_OWNER );
                   data.add( owner );
                   String description = jsonObject_local.getString( Constants.KEY_DESCRIPTION );
                   Log.i( "DESCRIPTION", description );
                   data.add( description ); 
                   String date = jsonObject_local.getString( Constants.KEY_DATE );
                   data.add( date );
                }
                else {
                    for( int i = 0; i < 4; i++ ) {
                        data.add( "ERROR" );
                    }
                }
          }
  }  //JSON object is null
  catch ( JSONException jsone) {
      Log.e( "JSON EXCEPTION", jsone.getMessage() );
  }
      dummyData = data.toArray( dummyData );
  }
  return dummyData;

}

I've heard stories that they were to be included close to the orignal Java release. Oak was the precursor to Java, and in some spec documents there was mention of usigned values. Unfortunately these never made it into the Java language. As far as anyone has been able to figure out they just didn't get implemented, likely due to a time constraint.

here is my recursive solution.

vector<vector<int> > getSubsets(vector<int> a){


//base case
    //if there is just one item then its subsets are that item and empty item
    //for example all subsets of {1} are {1}, {}

    if(a.size() == 1){
        vector<vector<int> > temp;
        temp.push_back(a);

        vector<int> b;
        temp.push_back(b);

        return temp;

    }
    else
    {


         //here is what i am doing

         // getSubsets({1, 2, 3})
         //without = getSubsets({1, 2})
         //without = {1}, {2}, {}, {1, 2}

         //with = {1, 3}, {2, 3}, {3}, {1, 2, 3}

         //total = {{1}, {2}, {}, {1, 2}, {1, 3}, {2, 3}, {3}, {1, 2, 3}}

         //return total

        int last = a[a.size() - 1];

        a.pop_back();

        vector<vector<int> > without = getSubsets(a);

        vector<vector<int> > with = without;

        for(int i=0;i<without.size();i++){

            with[i].push_back(last);

        }

        vector<vector<int> > total;

        for(int j=0;j<without.size();j++){
            total.push_back(without[j]);
        }

        for(int k=0;k<with.size();k++){
            total.push_back(with[k]);
        }


        return total;
    }


}

A more groovyesque approach would be to use inject in combination with metaClass:

I would to love to say:

String myInput="This string is FORBIDDEN"
myInput.containsAny(["FORBIDDEN","NOT_ALLOWED"]) //=>true

And the method would be:

myInput.metaClass.containsAny={List<String> notAllowedTerms->
   notAllowedTerms?.inject(false,{found,term->found || delegate.contains(term)})
}

If you need containsAny to be present for any future String variable then add the method to the class instead of the object:

String.metaClass.containsAny={notAllowedTerms->
   notAllowedTerms?.inject(false,{found,term->found || delegate.contains(term)})
}

I created a small working "migration file generator". It creates files which are working perfectly fine using sequelize db:migrate - even with foreign keys!

You can find it here: https://gist.github.com/manuelbieh/ae3b028286db10770c81

I tested it in an application with 12 different models covering:

• STRING, TEXT, ENUM, INTEGER, BOOLEAN, FLOAT as DataTypes

• Foreign key constraints (even reciprocal (user belongsTo team, team belongsTo user as owner))

• Indexes with name, method and unique properties

I'd suggest you go the other way around by writing unobtrusive JavaScript.

Make the features of your project work for users with JavaScript disabled, and when you're done, implement your JavaScript UI-enhancements.

https://en.wikipedia.org/wiki/Unobtrusive_JavaScript

There is no native map to the Object object, but how about this:

var myObject = { 'a': 1, 'b': 2, 'c': 3 };_x000D_
_x000D_
Object.keys(myObject).map(function(key, index) {_x000D_
  myObject[key] *= 2;_x000D_
});_x000D_
_x000D_
console.log(myObject);_x000D_
// => { 'a': 2, 'b': 4, 'c': 6 }

But you could easily iterate over an object using for ... in:

var myObject = { 'a': 1, 'b': 2, 'c': 3 };_x000D_
_x000D_
for (var key in myObject) {_x000D_
  if (myObject.hasOwnProperty(key)) {_x000D_
    myObject[key] *= 2;_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log(myObject);_x000D_
// { 'a': 2, 'b': 4, 'c': 6 }

Update

A lot of people are mentioning that the previous methods do not return a new object, but rather operate on the object itself. For that matter I wanted to add another solution that returns a new object and leaves the original object as it is:

var myObject = { 'a': 1, 'b': 2, 'c': 3 };_x000D_
_x000D_
// returns a new object with the values at each key mapped using mapFn(value)_x000D_
function objectMap(object, mapFn) {_x000D_
  return Object.keys(object).reduce(function(result, key) {_x000D_
    result[key] = mapFn(object[key])_x000D_
    return result_x000D_
  }, {})_x000D_
}_x000D_
_x000D_
var newObject = objectMap(myObject, function(value) {_x000D_
  return value * 2_x000D_
})_x000D_
_x000D_
console.log(newObject);_x000D_
// => { 'a': 2, 'b': 4, 'c': 6 }_x000D_
_x000D_
console.log(myObject);_x000D_
// => { 'a': 1, 'b': 2, 'c': 3 }

Array.prototype.reduce reduces an array to a single value by somewhat merging the previous value with the current. The chain is initialized by an empty object {}. On every iteration a new key of myObject is added with twice the key as the value.

Update

With new ES6 features, there is a more elegant way to express objectMap.

const objectMap = (obj, fn) =>_x000D_
  Object.fromEntries(_x000D_
    Object.entries(obj).map(_x000D_
      ([k, v], i) => [k, fn(v, k, i)]_x000D_
    )_x000D_
  )_x000D_
  _x000D_
const myObject = { a: 1, b: 2, c: 3 }_x000D_
_x000D_
console.log(objectMap(myObject, v => 2 * v)) 

You need to run the script as source or the shorthand .

source ./myscript.sh

or

. ./myscript.sh

This will run within the existing shell, ensuring any variables created or modified by the script will be available after the script completes.

Running the script just using the filename will execute the script in a separate subshell.

There is also a project on Github that aims to be a more direct port of the jQuery.extend():

https://github.com/dreamerslab/node.extend

An example, modified from the jQuery docs:

var extend = require('node.extend');

var object1 = {
    apple: 0,
    banana: {
        weight: 52,
        price: 100
    },
    cherry: 97
};

var object2 = {
    banana: {
        price: 200
    },
    durian: 100
};

var merged = extend(object1, object2);

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

for (int i = 0; i < dr_art_line_2.Rows.Count; i++)
{
    QuantityInIssueUnit_value = Convert.ToInt32(dr_art_line_2.Rows[i]["columnname"]);
    //Similarly for QuantityInIssueUnit_uom.
}

There are three scenarios (that I can think of) where you would call a method in a subclass where the method exits in the parent class:

1. Method is not overwritten by subclass, only exists in parent.

   This is the same as your example, and generally it's better to use $this -> get_species(); You are right that in this case the two are effectively the same, but the method has been inherited by the subclass, so there is no reason to differentiate. By using $this you stay consistent between inherited methods and locally declared methods.

2. Method is overwritten by the subclass and has totally unique logic from the parent.

   In this case, you would obviously want to use $this -> get_species(); because you don't want the parent's version of the method executed. Again, by consistently using $this, you don't need to worry about the distinction between this case and the first.

3. Method extends parent class, adding on to what the parent method achieves.

   In this case, you still want to use `$this -> get_species(); when calling the method from other methods of the subclass. The one place you will call the parent method would be from the method that is overwriting the parent method. Example:

   abstract class Animal {
   
       function get_species() {
   
           echo "I am an animal.";
   
       }
   
    }
   
    class Dog extends Animal {
   
        function __construct(){
   
            $this->get_species();
        }
   
        function get_species(){
   
            parent::get_species();
            echo "More specifically, I am a dog.";
        }
   }
   

The only scenario I can imagine where you would need to call the parent method directly outside of the overriding method would be if they did two different things and you knew you needed the parent's version of the method, not the local. This shouldn't be the case, but if it did present itself, the clean way to approach this would be to create a new method with a name like get_parentSpecies() where all it does is call the parent method:

function get_parentSpecies(){

     parent::get_species();
}

Again, this keeps everything nice and consistent, allowing for changes/modifications to the local method rather than relying on the parent method.

This worked like magic for me.

celltype_hesc_bool = expr['cell_type'] == 'hesc'

expr_celltype_hesc = expr[celltype_hesc]

A clean if/else conditional shell script:

if ./somecommand | grep -q 'some_string'; then
  echo "exists"
else
  echo "doesn't exist"
fi

I think the java.lang.UnsupportedOperationException is what you are looking for.

Use 'w' and not, 'a'.

if (!$handle = fopen($file, 'w'))

Based on Anastasiya's answer. I think this is the shortest vba command:

Option Explicit

Sub Sample()
    Dim sColumnLetter as String
    Dim iColumnNumber as Integer

    sColumnLetter = "C"
    iColumnNumber = Columns(sColumnLetter).Column

    MsgBox "The column number is " & iColumnNumber
End Sub

Caveat: The only condition for this code to work is that a worksheet is active, because Columns is equivalent to ActiveSheet.Columns. ;)

You can wrap and unwrap exceptions this way.

class A {
    void foo() throws Exception {
        throw new Exception();
    }
};

interface Task {
    void run() throws Exception;
}

static class TaskException extends RuntimeException {
    private static final long serialVersionUID = 1L;
    public TaskException(Exception e) {
        super(e);
    }
}

void bar() throws Exception {
      Stream<A> as = Stream.generate(()->new A());
      try {
        as.forEach(a -> wrapException(() -> a.foo())); // or a::foo instead of () -> a.foo()
    } catch (TaskException e) {
        throw (Exception)e.getCause();
    }
}

static void wrapException(Task task) {
    try {
        task.run();
    } catch (Exception e) {
        throw new TaskException(e);
    }
}

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"
EOF
ansible-playbook -v test.yml

Gradle 6.3, Java library. The code from "jar task" adds the dependencies to the "build/libs/xyz.jar" when running "gradle build" task.

plugins {

}

        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

Delete and Reset the prefix

$ npm config delete prefix 
$ npm config set prefix $NVM_DIR/versions/node/v6.11.1

Note: Change the version number with the one indicated in the error message.

nvm is not compatible with the npm config "prefix" option: currently set to "/usr/local" Run "npm config delete prefix" or "nvm use --delete-prefix v6.11.1 --silent" to unset it.

Using ES6 the javascript becomes a little cleaner

handleFiles(input) {

    const file = input.target.files[0];
    const reader = new FileReader();

    reader.onload = (event) => {
        const file = event.target.result;
        const allLines = file.split(/\r\n|\n/);
        // Reading line by line
        allLines.forEach((line) => {
            console.log(line);
        });
    };

    reader.onerror = (event) => {
        alert(event.target.error.name);
    };

    reader.readAsText(file);
}

This worked for me ...

Install nodemon as a local dev dependency

npm install --save-dev nodemon

Add script to your application package.json to start the application.

"scripts": {
  "start": "nodemon app.js"
},

Start nodemon with npm start

$ npm start

> [email protected] start node-rest-demo
> nodemon app.js

[nodemon] 1.19.4 [nodemon] to restart at any time, enter `rs` [nodemon] watching dir(s): *.* [nodemon] watching extensions: js,mjs,json [nodemon] starting `node app.js` Starting server ...

You can start your session with

export HISTFILE=/dev/null ;history -d $(history 1)

then proceed with your sneaky doings. Setting the histfile to /dev/null will be logged to the history file, yet this entry will be readily deleted and no traces (at least in the history file) will be shown.

Also, this is non-permanent.

Max. capacity is 2 gigabytes of space - so you're looking at just over 1 billion 2-byte characters that will fit into a NVARCHAR(MAX) field.

Using the other answer's more detailed numbers, you should be able to store

(2 ^ 31 - 1 - 2) / 2 = 1'073'741'822 double-byte characters

1 billion, 73 million, 741 thousand and 822 characters to be precise

in your NVARCHAR(MAX) column (unfortunately, that last half character is wasted...)

Update: as @MartinMulder pointed out: any variable length character column also has a 2 byte overhead for storing the actual length - so I needed to subtract two more bytes from the 2 ^ 31 - 1 length I had previously stipulated - thus you can store 1 Unicode character less than I had claimed before.

You can use lookups in Ansible in order to get the contents of a file, e.g.

user_data: "{{ lookup('file', user_data_file) }}"

Caveat: This lookup will work with local files, not remote files.

Here's a complete example from the docs:

- hosts: all
  vars:
     contents: "{{ lookup('file', '/etc/foo.txt') }}"
  tasks:
     - debug: msg="the value of foo.txt is {{ contents }}"

Like this for the server ip:

$_SERVER['SERVER_ADDR'];

and this for the port

$_SERVER['SERVER_PORT'];

As pointed out in this answer, Django 1.9 added the Field.disabled attribute:

The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in favor of the value from the form’s initial data.

With Django 1.8 and earlier, to disable entry on the widget and prevent malicious POST hacks you must scrub the input in addition to setting the readonly attribute on the form field:

class ItemForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(ItemForm, self).__init__(*args, **kwargs)
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            self.fields['sku'].widget.attrs['readonly'] = True

    def clean_sku(self):
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            return instance.sku
        else:
            return self.cleaned_data['sku']

Or, replace if instance and instance.pk with another condition indicating you're editing. You could also set the attribute disabled on the input field, instead of readonly.

The clean_sku function will ensure that the readonly value won't be overridden by a POST.

Otherwise, there is no built-in Django form field which will render a value while rejecting bound input data. If this is what you desire, you should instead create a separate ModelForm that excludes the uneditable field(s), and just print them inside your template.

A better way to do a break line is using span with CSS style parameter white-space: nowrap;

span.nobreak {
  white-space: nowrap;
}

or
span.nobreak {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Example directly in your HTML

<span style='overflow:hidden; white-space: nowrap;'> YOUR EXTENSIVE TEXT THAT YOU CAN´T BREAK LINE ....</span>

I know this is an old question, however here is a simple one-liner to switch it on or off depending on its current state:

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable -value (-not ([bool](get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable).proxyenable))

Another easy way is to set the logger like this- ensure that you do it before you load the cxf web service related classes. You can use it in some static blocks.

YourClientConstructor() {

  LogUtils.setLoggerClass(org.apache.cxf.common.logging.Log4jLogger.class);

  URL wsdlURL = YOurURL;//

  //create the service
  YourService = new YourService(wsdlURL, SERVICE_NAME);
  port = yourService.getServicePort(); 

  Client client = ClientProxy.getClient(port);
  client.getInInterceptors().add(new LoggingInInterceptor());
  client.getOutInterceptors().add(new LoggingOutInterceptor());
}

Then the inbound and outbound messages will be printed to Log4j file instead of the console. Make sure your log4j is configured properly

One thing you could try is using the following css:

.child-element {
    padding-left: inherit;
    padding-right: inherit;
    position: absolute;
    left: 0;
    right: 0;
}

It lets the child element inherit the padding from the parent, then the child can be positioned to match the parents widht and padding.

Also, I am using box-sizing: border-box; for the elements involved.

I have not tested this in all browsers, but it seems to be working in Chrome, Firefox and IE10.

This is fastest way I know of, even though you said you didn't want to use regular expressions:

Regex.Replace(XML, @"\s+", "")

you can also try

var query = from p in list
            where p.Age > 18
            select p;

Update 2018 Bootstrap 4

In Boostrap 4, the .open class has been replaced with .show. I wanted to implement this using only CSS transistions without the need for extra JS or jQuery...

.show > .dropdown-menu {
  max-height: 900px;
  visibility: visible;
}

.dropdown-menu {
  display: block;
  max-height: 0;
  visibility: hidden;
  transition: all 0.5s ease-in-out;
  overflow: hidden;
}

Demo: https://www.codeply.com/go/3i8LzYVfMF

Note: max-height can be set to any large value that's enough to accommodate the dropdown content.

For the following statement shared by Alex Booker in their answer

When the compiler encounters an expression-bodied property member, it essentially converts it to a getter like this:

Please see the following screenshot, it shows how this statement (using SharpLab link)

public string APIBasePath => Configuration.ToolsAPIBasePath;

converts to

public string APIBasePath
{
    get
    {
        return Configuration.ToolsAPIBasePath;
    }
}

Just an addition to the solved answer:

This COULD be a problem with Android Studio's Instant Run feature, for example, if you realized you forgot to add the line of code: finish() to your activity after opening another one, and you already re-opened the activity you shouldn't have reopened (which the finish() solved), then you add finish() and Instant Run occurs, then the app will crash since the logic has been broken.

TL:DR;

This is not necessarily a code problem, just an Instant Run problem

As Sagiv b.g. pointed out, the npm start command is a shortcut for npm run start. I just wanted to add a real-life example to clarify it a bit more.

The setup below comes from the create-react-app github repo. The package.json defines a bunch of scripts which define the actual flow.

"scripts": {
  "start": "npm-run-all -p watch-css start-js",
  "build": "npm run build-css && react-scripts build",
  "watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive",
  "build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/",
  "start-js": "react-scripts start"
},

For clarity, I added a diagram.

The blue boxes are references to scripts, all of which you could executed directly with an npm run <script-name> command. But as you can see, actually there are only 2 practical flows:

• npm run start
• npm run build

The grey boxes are commands which can be executed from the command line.

So, for instance, if you run npm start (or npm run start) that actually translate to the npm-run-all -p watch-css start-js command, which is executed from the commandline.

In my case, I have this special npm-run-all command, which is a popular plugin that searches for scripts that start with "build:", and executes all of those. I actually don't have any that match that pattern. But it can also be used to run multiple commands in parallel, which it does here, using the -p <command1> <command2> switch. So, here it executes 2 scripts, i.e. watch-css and start-js. (Those last mentioned scripts are watchers which monitor file changes, and will only finish when killed.)

• The watch-css makes sure that the *.scss files are translated to *.cssfiles, and looks for future updates.

• The start-js points to the react-scripts start which hosts the website in a development mode.

In conclusion, the npm start command is configurable. If you want to know what it does, then you have to check the package.json file. (and you may want to make a little diagram when things get complicated).

In my case I've used this:

var query = "select * from table where Id IN @Ids";
var result = conn.Query<MyEntity>(query, new { Ids = ids });

my variable "ids" in the second line is an IEnumerable of strings, also they can be integers I guess.

• %lu for unsigned long
• %llu for unsigned long long

if (element.nodeName == "A") {
 ...
} else if (element.nodeName == "TD") {
 ...
}

Using CSS, you set the logo div to position absolute, and set the z-order to be above the second div.

#logo
{
    position: absolute:
    z-index: 2000;
    left: 100px;
    width: 100px;
    height: 50px;
}

Or this:

f(x)=\begin{cases}
0, & -\pi\leqslant x <0\\
\pi, & 0 \leqslant x \leqslant +\pi
\end{cases}

if (!file_exists('http://example.com/images/thumbnail_1286954822.jpg')) {   
$filefound = '0';
}

Even though this is a pretty old questions with multiple accepted answers, I'd like to share how to resolve an obscure "undefined reference to" error.

Different versions of libraries

I was using an alias to refer to std::filesystem::path: filesystem is in the standard library since C++17 but my program needed to also compile in C++14 so I decided to use a variable alias:

#if (defined _GLIBCXX_EXPERIMENTAL_FILESYSTEM) //is the included filesystem library experimental? (C++14 and newer: <experimental/filesystem>)
using path_t = std::experimental::filesystem::path;
#elif (defined _GLIBCXX_FILESYSTEM) //not experimental (C++17 and newer: <filesystem>)
using path_t = std::filesystem::path;
#endif

Let's say I have three files: main.cpp, file.h, file.cpp:

• file.h #include's <experimental::filesystem> and contains the code above
• file.cpp, the implementation of file.h, #include's "file.h"
• main.cpp #include's <filesystem> and "file.h"

Note the different libraries used in main.cpp and file.h. Since main.cpp #include'd "file.h" after <filesystem>, the version of filesystem used there was the C++17 one. I used to compile the program with the following commands:

$ g++ -g -std=c++17 -c main.cpp -> compiles main.cpp to main.o
$ g++ -g -std=c++17 -c file.cpp -> compiles file.cpp and file.h to file.o
$ g++ -g -std=c++17 -o executable main.o file.o -lstdc++fs -> links main.o and file.o

This way any function contained in file.o and used in main.o that required path_t gave "undefined reference" errors because main.o referred to std::filesystem::path but file.o to std::experimental::filesystem::path.

Resolution

To fix this I just needed to change <experimental::filesystem> in file.h to <filesystem>.

but the file i am getting from server after download it gives the size of 226 bytes

This is the size of a ZIP header. Apparently there is no data in the downloaded ZIP file. So, can you verify that the files to be added into the ZIP file are, indeed, there (relative to the path of the download PHP script)?

Consider adding a check on addFile too:

foreach($file_names as $file)
{
    $inputFile = $file_path . $file;
    if (!file_exists($inputFile))
        trigger_error("The input file $inputFile does not exist", E_USER_ERROR);
    if (!is_readable($inputFile))
        trigger_error("The input file $inputFile exists, but has wrong permissions or ownership", E_USER_ERROR);
    if (!$zip->addFile($inputFile, $file))
        trigger_error("Could not add $inputFile to ZIP file", E_USER_ERROR);
}

The observed behaviour is consistent with some problem (path error, permission problems, ...) preventing the files from being added to the ZIP file. On receiving an "empty" ZIP file, the client issues an error referring to the ZIP central directory missing (the actual error being that there is no directory, and no files).

The Ternary operator is just written as a boolean expression followed by a questionmark and then two further expressions separated by a colon.

The first thing that I can see that you have got wrong is that your first expression isn't returning a boolean or anything sensible that could be converted to a boolean. Your first expression is always going to return a jQuery object that has no sensible interpretation as a boolean and what it does convert to is probably an unchanging interpretation. You are always best off returning something that has a well known boolean interpretation, if nothign else for the sake of readability.

The second thing is that you are putting a semicolon after each of your expressions which is wrong. In effect this is saying "end of construct" and so is breaking your ternary operator.

In this situation though you probably can do this a more easy way. If you use classes and the toggleClass method then you can easily get it to switch a class on and off and then you can put your styles in that class definition (Kudos to @yoavmatchulsky for suggesting use of classes up there in comments).

A fiddle of this is found here: http://jsfiddle.net/chrisvenus/wSMnV/ (based on the original)

Just for clarification: a table can have at most one primary key. A primary key consists of one or more columns (from that table). If a primary key consists of two or more columns it is called a composite primary key. It is defined as follows:

CREATE TABLE voting (
  QuestionID NUMERIC,
  MemberID NUMERIC,
  PRIMARY KEY (QuestionID, MemberID)
);

The pair (QuestionID,MemberID) must then be unique for the table and neither value can be NULL. If you do a query like this:

SELECT * FROM voting WHERE QuestionID = 7

it will use the primary key's index. If however you do this:

SELECT * FROM voting WHERE MemberID = 7

it won't because to use a composite index requires using all the keys from the "left". If an index is on fields (A,B,C) and your criteria is on B and C then that index is of no use to you for that query. So choose from (QuestionID,MemberID) and (MemberID,QuestionID) whichever is most appropriate for how you will use the table.

If necessary, add an index on the other:

CREATE UNIQUE INDEX idx1 ON voting (MemberID, QuestionID);

I think the problem is that you are using type="text" instead of textarea. What you want is:

<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>

To clarify, a type="text" will always be one row, where-as a textarea can be multiple.

I thought the question was "Move cursor to end of file in vim" ?

Retuning false from a JavaScript event usually cancels the "default" behavior - in the case of links, it tells the browser to not follow the link.

instead of

document.getElementById("txtBillingGroupName").value = groupName;

You can use

$("#txtBillingGroupName").val(groupName);

instead of groupName you can pass string value like "Group1"

You can use round function. Here some example

numpy.round([2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01],2)
array([ 21.53,   8.13,   3.97,  10.08])

IF you want change just display representation, I would not recommended to alter printing format globally, as it suggested above. I would format my output in place.

>>a=np.array([2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01])
>>> print([ "{:0.2f}".format(x) for x in a ])
['21.53', '8.13', '3.97', '10.08']

I also met this problem just now and solved it in this way. So I recorded it here, and I wish it be useful for others.

Scenario:

1. Before I commit the code, revision: 100
2. (Someone else commits the code... revision increased to 199)
3. I (forgot to run "svn up", ) commit the code, now my revision: 200
4. I run "svn up".

The error occurred.

Solution:

1. $ mv current_copy copy_back # Rename the current code copy
2. $ svn checkout current_copy # Check it out again
3. $ cp copy_back/ current_copy # Restore your modifications

var newTH = document.createElement('th');
newTH.innerHTML = 'Hello, World!';
newTH.onclick = function () {
    this.parentElement.removeChild(this);
};

var table = document.getElementById('content');
table.appendChild(newTH);

You can also just hide with this.style.display = 'none'.

PHP runs in the server. JavaScript runs in the client. So php can't call a JavaScript function.

Permanent for all users (when you alone on server):

# echo "set tabstop=4" >> /etc/vim/vimrc

Appends the setting in the config file. Normally on new server apt-get purge nano mc and all other to save your time. Otherwise, you will redefine editor in git, crontab etc.

My favorite: Smart::Comments

use Smart::Comments;
# ...

That's it.

you can achive this by calling a function also

<div [style.width.px]="getCustomeWidth()"></div>

  getCustomeWidth() {
    //do what ever you want here
    return customeWidth;
  }

As @Graham42 said, from version 2.1 mouse options has been renamed but you can use the mouse with any version of tmux adding this to your ~/.tmux.conf:

if-shell "$is_pre_2_1" "setw -g mode-mouse on; set -g mouse-resize-pane on;\
      set -g mouse-select-pane on; set -g mouse-select-window on" "set -g mouse on"

Sh (Bourne shell) shells:

is_pre_2_1="tmux -V | cut -d' ' -f2 | awk '{print ($0 < 2.1) ? "true" : "false"}'"
if-shell "$is_pre_2_1" "setw -g mode-mouse on; set -g mouse-resize-pane on;\
      set -g mouse-select-pane on; set -g mouse-select-window on" "set -g mouse on"

You could always use mysql's LOAD DATA:

LOAD DATA LOCAL INFILE '/full/path/to/file/foo.csv' INTO TABLE `footable` FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n' 

to do bulk inserts rather than using a bunch of INSERT statements.

Ran into a similar issue, in that creating custom error messages for my custom exceptions make ugly code. This was my solution:

class MyRunTimeException: public std::runtime_error
{
public:
      MyRunTimeException(const std::string &filename):std::runtime_error(GetMessage(filename)) {}
private:
      static std::string GetMessage(const std::string &filename)
     {
           // Do your message formatting here. 
           // The benefit of returning std::string, is that the compiler will make sure the buffer is good for the length of the constructor call
           // You can use a local std::ostringstream here, and return os.str()
           // Without worrying that the memory is out of scope. It'll get copied
           // You also can create multiple GetMessage functions that take all sorts of objects and add multiple constructors for your exception
     }
}

This separates the logic for creating the messages. I had originally thought about overriding what(), but then you have to capture your message somewhere. std::runtime_error already has an internal buffer.

Add position:fixed. Then the cover is fixed over the whole screen, also when you scroll.
And add maybe also margin: 0; padding:0; so it wont have some space's around the cover.

#dimScreen
{
    position:fixed;
    padding:0;
    margin:0;

    top:0;
    left:0;

    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);
}

And if it shouldn't stick on the screen fixed, use position:absolute;

CSS Tricks have also an interesting article about fullscreen property.

Edit:
Just came across this answer, so I wanted to add some additional things.
Like Daniel Allen Langdon mentioned in the comment, add top:0; left:0; to be sure, the cover sticks on the very top and left of the screen.

If you some elements are at the top of the cover (so it doesn't cover everything), then add z-index. The higher the number, the more levels it covers.

Maybe you are trying to set it in Apache's php.ini, but your CLI (Command Line Interface) php.ini is not good.

Find your php.ini file with the following command:

php -i | grep php.ini

And then search for date.timezone and set it to "Europe/Amsterdam". all valid timezone will be found here http://php.net/manual/en/timezones.php

Another way (if the other does not work), search for the file AppKernel.php, which should be under the folder app of your Symfony project directory. Overwrite the __construct function below in the class AppKernel:

<?php     

class AppKernel extends Kernel
{
    // Other methods and variables


    // Append this init function below

    public function __construct($environment, $debug)
    {
        date_default_timezone_set( 'Europe/Paris' );
        parent::__construct($environment, $debug);
    }

}

There's a function called dropNamed() in Bernd Bischl's BBmisc package that does exactly this.

BBmisc::dropNamed(df, "x")

The advantage is that it avoids repeating the data frame argument and thus is suitable for piping in magrittr (just like the dplyr approaches):

df %>% BBmisc::dropNamed("x")

If you are not sure if the call to "back" will exit the app, or will take the user to another activity, you can wrap the above answers in a check, isTaskRoot(). This can happen if your main activity can be added to the back stack multiple times, or if you are manipulating your back stack history.

if(isTaskRoot()) {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Are you sure you want to exit?")
       .setCancelable(false)
       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                YourActivity.super.onBackPressed;
           }
       })
       .setNegativeButton("No", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
           }
       });
    AlertDialog alert = builder.create();
    alert.show();

} else {
    super.onBackPressed();
}

I came up with an alternative that actually hides sections and doesn't delete them. I tried @henning77's approach, but I kept running into problems when I changed the number of sections of the static UITableView. This method has worked really well for me, but I'm primarily trying to hide sections instead of rows. I am removing some rows on the fly successfully, but it is a lot messier, so I've tried to group things into sections that I need to show or hide. Here is an example of how I'm hiding sections:

First I declare a NSMutableArray property

@property (nonatomic, strong) NSMutableArray *hiddenSections;

In the viewDidLoad (or after you have queried your data) you can add sections you want to hide to the array.

- (void)viewDidLoad
{
    hiddenSections = [NSMutableArray new];

    if(some piece of data is empty){
        // Add index of section that should be hidden
        [self.hiddenSections addObject:[NSNumber numberWithInt:1]];
    }

    ... add as many sections to the array as needed

    [self.tableView reloadData];
}

Then implement the following the TableView delegate methods

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    if([self.hiddenSections containsObject:[NSNumber numberWithInt:section]]){
        return nil;
    }

    return [super tableView:tableView titleForHeaderInSection:section];
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if([self.hiddenSections containsObject:[NSNumber numberWithInt:indexPath.section]]){
        return 0;
    }

    return [super tableView:tableView heightForRowAtIndexPath:[self offsetIndexPath:indexPath]];
}

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if([self.hiddenSections containsObject:[NSNumber numberWithInt:indexPath.section]]){
        [cell setHidden:YES];
    }
}

Then set the header and footer height to 1 for hidden sections because you can't set the height to 0. This causes an additional 2 pixel space, but we can make up for it by adjusting the height of the next visible header.

-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section 
{
    CGFloat height = [super tableView:tableView heightForHeaderInSection:section];

    if([self.hiddenSections containsObject:[NSNumber numberWithInt:section]]){
        height = 1; // Can't be zero
    }
    else if([self tableView:tableView titleForHeaderInSection:section] == nil){ // Only adjust if title is nil
        // Adjust height for previous hidden sections
        CGFloat adjust = 0;

        for(int i = (section - 1); i >= 0; i--){
            if([self.hiddenSections containsObject:[NSNumber numberWithInt:i]]){
                adjust = adjust + 2;
            }
            else {
                break;
            }
        }

        if(adjust > 0)
        {                
            if(height == -1){
                height = self.tableView.sectionHeaderHeight;
            }

            height = height - adjust;

            if(height < 1){
                height = 1;
            }
        }
    }

    return height;
}

-(CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section 
{   
    if([self.hiddenSections containsObject:[NSNumber numberWithInt:section]]){
        return 1;
    }
    return [super tableView:tableView heightForFooterInSection:section];
}

Then, if you do have specific rows to hide you can adjust the numberOfRowsInSection and which rows are returned in cellForRowAtIndexPath. In this example here I have a section that has three rows where any three could be empty and need to be removed.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSInteger rows = [super tableView:tableView numberOfRowsInSection:section];

    if(self.organization != nil){
        if(section == 5){ // Contact
            if([self.organization objectForKey:@"Phone"] == [NSNull null]){     
                rows--;
            }

            if([self.organization objectForKey:@"Email"] == [NSNull null]){     
                rows--;
            }

            if([self.organization objectForKey:@"City"] == [NSNull null]){     
                rows--;
            }
        }
    }

    return rows;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{    
    return [super tableView:tableView cellForRowAtIndexPath:[self offsetIndexPath:indexPath]];
}

Use this offsetIndexPath to calculate the indexPath for rows where you are conditionally removing rows. Not needed if you are only hiding sections

- (NSIndexPath *)offsetIndexPath:(NSIndexPath*)indexPath
{
    int row = indexPath.row;

    if(self.organization != nil){
        if(indexPath.section == 5){
            // Adjust row to return based on which rows before are hidden
            if(indexPath.row == 0 && [self.organization objectForKey:@"Phone"] == [NSNull null] && [self.organization objectForKey:@"Email"] != [NSNull null]){     
                row++;
            }
            else if(indexPath.row == 0 && [self.organization objectForKey:@"Phone"] == [NSNull null] && [self.organization objectForKey:@"Address"] != [NSNull null]){     
                row = row + 2;
            }
            else if(indexPath.row == 1 && [self.organization objectForKey:@"Phone"] != [NSNull null] && [self.organization objectForKey:@"Email"] == [NSNull null]){     
                row++;
            }
            else if(indexPath.row == 1 && [self.organization objectForKey:@"Phone"] == [NSNull null] && [self.organization objectForKey:@"Email"] != [NSNull null]){     
                row++;
            }
        }
    }

    NSIndexPath *offsetPath = [NSIndexPath indexPathForRow:row inSection:indexPath.section];

    return offsetPath;
}

There are a lot of methods to override, but what I like about this approach is that it is re-usable. Setup the hiddenSections array, add to it, and it will hide the correct sections. Hiding the rows it a little trickier, but possible. We can't just set the height of the rows we want to hide to 0 if we're using a grouped UITableView because the borders will not get drawn correctly.

My images were not getting displayed even after putting them in the correct folder, problem was they did not have the right permission, I changed the permission to read write execute. I used chmod 777 image.png. All worked then, images were getting displayed. :)

Use disabled true property

<TouchableOpacity disabled={true}> </TouchableOpacity>

return "default" if x is None else x

try the above.

An org.json.JSONArray is not iterable.
Here's how I process elements in a net.sf.json.JSONArray:

    JSONArray lineItems = jsonObject.getJSONArray("lineItems");
    for (Object o : lineItems) {
        JSONObject jsonLineItem = (JSONObject) o;
        String key = jsonLineItem.getString("key");
        String value = jsonLineItem.getString("value");
        ...
    }

Works great... :)

You can do it using the fs-extra module very easily:

const fse = require('fs-extra');

let srcDir = 'path/to/file';
let destDir = 'pat/to/destination/directory';

fse.moveSync(srcDir, destDir, function (err) {

    // To move a file permanently from a directory
    if (err) {
        console.error(err);
    } else {
        console.log("success!");
    }
});

Or

fse.copySync(srcDir, destDir, function (err) {

     // To copy a file from a directory
     if (err) {
         console.error(err);
     } else {
         console.log("success!");
     }
});

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

Way out for me was to add

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

annotation to class running Spring boot (marked with `@SpringBootApplication).

Finally, it looks like:

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class Application{

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
 }

I faced same issue while using card-columns

i fixed it using

 display: inline-flex ;
 column-break-inside: avoid;
 width:100%;

There is a great library for it ts-json-object

In your case you would need to run the following code:

import {JSONObject, required} from 'ts-json-object'

class Response extends JSONObject {
    @required
    name: string;

    @required
    error: boolean;
}

let resp = new Response({"name": "Bob", "error": false});

This library will validate the json before parsing

Spring Boot 1.4 Use this for Javascript HTML Json all compressions.

server.compression.enabled: true
server.compression.mime-types: application/json,application/xml,text/html,text/xml,text/plain,text/css,application/javascript

Kris Erickson is right, vote him up. In my case the problem was installing TFS powertools , which adds explorer shell integration just like TSVN and TCVS. It adds another 5 overlays. Since they are prefixed with Tfs*, they take priority over Tortoise*. I also just prefixed the Tfs stuff with z_ and the TSVN overlays came back. No need to reboot/logoff though, just kill explorer.exe and start it again.

That's called SQL INJECTION. The ' tries to open/close a string in your mysql query. You should always escape any string that gets into your queries.

for example,

instead of this:

"VALUES ('$sender_id') "

do this:

"VALUES ('". mysql_real_escape_string($sender_id)  ."') "

(or equivalent, of course)

However, it's better to automate this, using PDO, named parameters, prepared statements or many other ways. Research about this and SQL Injection (here you have some techniques).

Hope it helps. Cheers

$("select#selectbox option:eq(0)").text()

The 0 index in the "option:eq(0)" can be exchanged for whichever indexed option you'd like to retrieve.

The problem I need to solve is to store contracts containing a few fields (address, book, num_of_days, borrower_addr, blk_data), blk_data is a transaction list (block number and transaction address). This question and answer helped me. I would like to share my code as below. Hope this helps.

1. Schema definition. See blk_data.

var ContractSchema = new Schema(
    {
        address: {type: String, required: true, max: 100},  //contract address
        // book_id: {type: String, required: true, max: 100},  //book id in the book collection
        book: { type: Schema.ObjectId, ref: 'clc_books', required: true }, // Reference to the associated book.
        num_of_days: {type: Number, required: true, min: 1},
        borrower_addr: {type: String, required: true, max: 100},
        // status: {type: String, enum: ['available', 'Created', 'Locked', 'Inactive'], default:'Created'},

        blk_data: [{
            tx_addr: {type: String, max: 100}, // to do: change to a list
            block_number: {type: String, max: 100}, // to do: change to a list
        }]
    }
);

2. Create a record for the collection in the MongoDB. See blk_data.

// Post submit a smart contract proposal to borrowing a specific book.
exports.ctr_contract_propose_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('req_addr', 'req_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('new_contract_addr', 'contract_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),
    body('num_of_days', 'num_of_days must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data and old id.
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                cur_contract: req.body.new_contract_addr,
                status: 'await_approval'
            };

        async.parallel({
            //call the function get book model
            books: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if (results.books.isNew) {
                // res.render('pg_error', {
                //     title: 'Proposing a smart contract to borrow the book',
                //     c: errors.array()
                // });
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var contract = new Contract(
                {
                    address: req.body.new_contract_addr,
                    book: req.body.book_id,
                    num_of_days: req.body.num_of_days,
                    borrower_addr: req.body.req_addr

                });

            var blk_data = {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                };
            contract.blk_data.push(blk_data);

            // Data from form is valid. Save book.
            contract.save(function (err) {
                if (err) { return next(err); }
                // Successful - redirect to new book record.
                resObj = {
                    "res": contract.url
                };
                res.status(200).send(JSON.stringify(resObj));
                // res.redirect();
            });

        });

    },
];

3. Update a record. See blk_data.

// Post lender accept borrow proposal.
exports.ctr_contract_propose_accept_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('contract_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                status: 'on_loan'
            };

        // Create a contract object with escaped/trimmed data
        var contract_fields = {
            $push: {
                blk_data: {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                }
            }
        };

        async.parallel({
            //call the function get book model
            book: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
            contract: function(callback) {
                Contract.findByIdAndUpdate(req.body.contract_id, contract_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if ((results.book.isNew) || (results.contract.isNew)) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var resObj = {
                "res": results.contract.url
            };
            res.status(200).send(JSON.stringify(resObj));
        });
    },
];

By using the Date object and its milliseconds value, differences can be calculated:

var a = new Date(); // Current date now.
var b = new Date(2010, 0, 1, 0, 0, 0, 0); // Start of 2010.
var d = (b-a); // Difference in milliseconds.

You can get the number of seconds (as a integer/whole number) by dividing the milliseconds by 1000 to convert it to seconds then converting the result to an integer (this removes the fractional part representing the milliseconds):

var seconds = parseInt((b-a)/1000);

You could then get whole minutes by dividing seconds by 60 and converting it to an integer, then hours by dividing minutes by 60 and converting it to an integer, then longer time units in the same way. From this, a function to get the maximum whole amount of a time unit in the value of a lower unit and the remainder lower unit can be created:

function get_whole_values(base_value, time_fractions) {
    time_data = [base_value];
    for (i = 0; i < time_fractions.length; i++) {
        time_data.push(parseInt(time_data[i]/time_fractions[i]));
        time_data[i] = time_data[i] % time_fractions[i];
    }; return time_data;
};
// Input parameters below: base value of 72000 milliseconds, time fractions are
// 1000 (amount of milliseconds in a second) and 60 (amount of seconds in a minute). 
console.log(get_whole_values(72000, [1000, 60]));
// -> [0,12,1] # 0 whole milliseconds, 12 whole seconds, 1 whole minute.

If you're wondering what the input parameters provided above for the second Date object are, see their names below:

new Date(<year>, <month>, <day>, <hours>, <minutes>, <seconds>, <milliseconds>);

As noted in the comments of this solution, you don't necessarily need to provide all these values unless they're necessary for the date you wish to represent.

The docs for Google Test 1.7 suggest:

"If you have a broken test that you cannot fix right away, you can add the DISABLED_ prefix to its name. This will exclude it from execution."

Examples:

// Tests that Foo does Abc.
TEST(FooTest, DISABLED_DoesAbc) { ... }

class DISABLED_BarTest : public ::testing::Test { ... };

// Tests that Bar does Xyz.
TEST_F(DISABLED_BarTest, DoesXyz) { ... }

DECLARE @source varbinary(max),  
@encoded_base64 varchar(max),  
@decoded varbinary(max) 
SET @source = CONVERT(varbinary(max), 'welcome') 
-- Convert from varbinary to base64 string 
SET @encoded_base64 = CAST(N'' AS xml).value('xs:base64Binary(sql:variable       
("@source"))', 'varchar(max)') 
  -- Convert back from base64 to varbinary 
   SET @decoded = CAST(N'' AS xml).value('xs:base64Binary(sql:variable             
  ("@encoded_base64"))', 'varbinary(max)') 

 SELECT
  CONVERT(varchar(max), @source) AS [Source varchar], 
   @source AS [Source varbinary], 
     @encoded_base64 AS [Encoded base64], 
     @decoded AS [Decoded varbinary], 
     CONVERT(varchar(max), @decoded) AS [Decoded varchar]

This is usefull for encode and decode.

Basend on the example of Gary Kerr and as proposed here one may create empty circles related to specified values with following code:

import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.markers import MarkerStyle

x = np.random.randn(60) 
y = np.random.randn(60)
z = np.random.randn(60)

g=plt.scatter(x, y, s=80, c=z)
g.set_facecolor('none')
plt.colorbar()
plt.show()

This must be a matter of http headers.

see here: HTTP Headers for File Downloads

The server should tell your browser to download the file by sending

Content-Type: application/octet-stream; 
Content-Disposition: attachment;

in the headers

"Empty": only works on variables. Empty can mean different things for different variable types (check manual: http://php.net/manual/en/function.empty.php).

"isset": checks if the variable exists and checks for a true NULL or false value. Can be unset by calling "unset". Once again, check the manual.

Use of either one depends of the variable type you are using.

I would say, it's safer to check for both, because you are checking first of all if the variable exists, and if it isn't really NULL or empty.

Oh there are many differences you will need to consider

Views for selection:

1. Views provide abstraction over tables. You can add/remove fields easily in a view without modifying your underlying schema
2. Views can model complex joins easily.
3. Views can hide database-specific stuff from you. E.g. if you need to do some checks using Oracles SYS_CONTEXT function or many other things
4. You can easily manage your GRANTS directly on views, rather than the actual tables. It's easier to manage if you know a certain user may only access a view.
5. Views can help you with backwards compatibility. You can change the underlying schema, but the views can hide those facts from a certain client.

Views for insertion/updates:

1. You can handle security issues with views by using such functionality as Oracle's "WITH CHECK OPTION" clause directly in the view

Drawbacks

1. You lose information about relations (primary keys, foreign keys)
2. It's not obvious whether you will be able to insert/update a view, because the view hides its underlying joins from you

Do you want the first and last name of the row with the largest id?

If so (and you were missing a FROM clause):

SELECT firstname, lastname, id
FROM foo
ORDER BY id DESC
LIMIT 1;

The official language specification for XPath 2.0 on W3.org details that the language does indeed support if statements. See Section 3.8 Conditional Expressions, in particular. Along with the syntax format and explanation, it gives the following example:

if ($widget1/unit-cost < $widget2/unit-cost) 
  then $widget1
  else $widget2

This would suggest that you shouldn't have brackets surrounding your expressions (otherwise the syntax looks correct). I'm not wholly confident, but it's surely worth a try. So you'll want to change your query to look like this:

if (fn:ends-with(//div [@id='head']/text(),': '))
  then fn:substring-before(//div [@id='head']/text(),': ')
  else //div [@id='head']/text()

I do strongly suspect this may fix it however, as the fact that your XPath engine seems to be trying to interpret if as a function, where it is in fact a special construct of the language.

Finally, to point out the obvious, insure that your XPath engine does in fact support XPath 2.0 (as opposed to an earlier version)! I don't believe conditional expressions are part of previous versions of XPath.

You can simply define the key to use directly when running the command:

ansible-playbook \
        \ # Super verbose output incl. SSH-Details:
    -vvvv \
        \ # The Server to target: (Keep the trailing comma!)
    -i "000.000.0.000," \
        \ # Define the key to use:
    --private-key=~/.ssh/id_rsa_ansible \
        \ # The `env` var is needed if `python` is not available:
    -e 'ansible_python_interpreter=/usr/bin/python3' \ # Needed if `python` is not available
        \ # Dry–Run:
    --check \
    deploy.yml

Copy/ Paste:

ansible-playbook -vvvv --private-key=/Users/you/.ssh/your_key deploy.yml

The data in COL1 is in dd-mon-yy

No it's not. A DATE column does not have any format. It is only converted (implicitely) to that representation by your SQL client when you display it.

If COL1 is really a DATE column using to_date() on it is useless because to_date() converts a string to a DATE.

You only need to_char(), nothing else:

SELECT TO_CHAR(col1, 'mm/dd/yyyy') 
FROM TABLE1

What happens in your case is that calling to_date() converts the DATE into a character value (applying the default NLS format) and then converting that back to a DATE. Due to this double implicit conversion some information is lost on the way.

Edit

So you did make that big mistake to store a DATE in a character column. And that's why you get the problems now.

The best (and to be honest: only sensible) solution is to convert that column to a DATE. Then you can convert the values to any rerpresentation that you want without worrying about implicit data type conversion.

But most probably the answer is "I inherited this model, I have to cope with it" (it always is, apparently no one ever is responsible for choosing the wrong datatype), then you need to use RR instead of YY:

SELECT TO_CHAR(TO_DATE(COL1,'dd-mm-rr'), 'mm/dd/yyyy')
FROM TABLE1

should do the trick. Note that I also changed mon to mm as your example is 27-11-89 which has a number for the month, not an "word" (like NOV)

For more details see the manual: http://docs.oracle.com/cd/B28359_01/server.111/b28286/sql_elements004.htm#SQLRF00215

SELECT * FROM table ORDER BY id DESC,datechat desc LIMIT 50

If you have a date field that is storing the date(and time) on which the chat was sent or any field that is filled with incrementally(order by DESC) or desinscrementally( order by ASC) data per row put it as second column on which the data should be order.

That's what worked for me!!!! hope it will help!!!!

I have never seen double-backslashed paths, are they existing? The built-in feature of python module os fails for those. All others work, also the caveat given by you with os.path.normpath():

paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c', 
...     'a/b/../../a/b/c/', 'a/b/../../a/b/c', 'a/./b/c', 'a\b/c']
for path in paths:
    os.path.basename(os.path.normpath(path))

In addition to all the other answers I'd like to note that if you want to write that number as a literal in your Java code, you'll need to append a L or l to tell the compiler that it's a long constant:

long l1 = 9999999999;  // this won't compile
long l2 = 9999999999L; // this will work

Use the Date property:

var dateAndTime = DateTime.Now;
var date = dateAndTime.Date;

The date variable will contain the date, the time part will be 00:00:00.

If I get you right, you want something that seems to be the opposite of what is desired normally: you want a horizontal layout for small screens and vertically stacked elements on large screens. You may achieve this in a way like this:

<div class="container">
    <div class="row">
        <div class="hidden-md hidden-lg col-xs-3 col-xs-offset-6">a</div>
        <div class="hidden-md hidden-lg col-xs-3">b</div>
    </div>
    <div class="row">
        <div class="hidden-xs hidden-sm">c</div>

    </div>
</div>

On small screens, i.e. xs and sm, this generates one row with two columns with an offset of 6. On larger screens, i.e. md and lg, it generates two vertically stacked elements in full width (12 columns).

Description and examples can be found in IEEE Std 1800-2017 § 11.5.1 "Vector bit-select and part-select addressing". First IEEE appearance is IEEE 1364-2001 (Verilog) § 4.2.1 "Vector bit-select and part-select addressing". Here is an direct example from the LRM:

logic [31: 0] a_vect;
logic [0 :31] b_vect;
logic [63: 0] dword;
integer sel;
a_vect[ 0 +: 8] // == a_vect[ 7 : 0]
a_vect[15 -: 8] // == a_vect[15 : 8]
b_vect[ 0 +: 8] // == b_vect[0 : 7]
b_vect[15 -: 8] // == b_vect[8 :15]
dword[8*sel +: 8] // variable part-select with fixed width

If sel is 0 then dword[8*(0) +: 8] == dword[7:0]
If sel is 7 then dword[8*(7) +: 8] == dword[63:56]

The value to the left always the starting index. The number to the right is the width and must be a positive constant. the + and - indicates to select the bits of a higher or lower index value then the starting index.

Assuming address is in little endian ([msb:lsb]) format, then if(address[2*pointer+:2]) is the equivalent of if({address[2*pointer+1],address[2*pointer]})

You probably finally realized this between posting this question and today, but the very nature of selectors makes it impossible to navigate through hierarchically unrelated HTML elements.

Or, to put it simply, since you said in your comment that

there are no uniform parent containers

... it's just not possible with selectors alone, without modifying the markup in some way as shown by the other answers.

You have to use the jQuery .eq() solution.

If I'm not mistaken, the default bean name of a bean declared with @Component is the name of its class its first letter in lower-case. This means that

@Component
public class SuggestionService {

declares a bean of type SuggestionService, and of name suggestionService. It's equivalent to

@Component("suggestionService")
public class SuggestionService {

or to

<bean id="suggestionService" .../>

You're redefining another bean of the same type, but with a different name, in the XML:

<bean id="SuggestionService" class="com.hp.it.km.search.web.suggestion.SuggestionService">
    ...
</bean>

So, either specify the name of the bean in the annotation to be SuggestionService, or use the ID suggestionService in the XML (don't forget to also modify the <ref> element, or to remove it, since it isn't needed). In this case, the XML definition will override the annotation definition.

It looks like you're not memory managing the view controller properly and it is being deallocated at some point - which causes the numberButtonClicked: method to be sent to another object that is now occupying the memory that the view controller was previously occupying...

Make sure you're properly retaining/releasing your view controller.

When you install Kafka in Centos7 with confluent :

yum install confluent-platform-oss-2.11

You can see the version of Kafka with :

yum deplist confluent-platform-oss-2.11

You can read : confluent-kafka-2.11 >= 0.10.2.1

I don't know if this helps, but when you subclass (including anonymously) a generic type, the type information is available via reflection. e.g.,

public abstract class Foo<E> {

  public E instance;  

  public Foo() throws Exception {
    instance = ((Class)((ParameterizedType)this.getClass().
       getGenericSuperclass()).getActualTypeArguments()[0]).newInstance();
    ...
  }

}

So, when you subclass Foo, you get an instance of Bar e.g.,

// notice that this in anonymous subclass of Foo
assert( new Foo<Bar>() {}.instance instanceof Bar );

But it's a lot of work, and only works for subclasses. Can be handy though.
