There is a HUGE difference between VARCHAR and TEXT. While VARCHAR fields can be indexed, TEXT fields cannot. VARCHAR type fields are stored inline while TEXT are stored offline, only pointers to TEXT data is actually stored in the records.

If you have to index your field for faster search, update or delete than go for VARCHAR, no matter how big. A VARCHAR(10000000) will never be the same as a TEXT field bacause these two data types are different in nature.

• If you use you field only for archiving
• you don't care about data speed retrival
• you care about speed but you will use the operator '%LIKE%' in your search query so indexing will not help much
• you can't predict a limit of the data length

than go for TEXT.

As suggested before, the clean way of deep copying objects having nested objects inside is by using lodash's cloneDeep method.

For Angular, you can do it like this:

Install lodash with yarn add lodash or npm install lodash.

In your component, import cloneDeep and use it:

import * as cloneDeep from 'lodash/cloneDeep';
...
clonedObject = cloneDeep(originalObject);

It's only 18kb added to your build, well worth for the benefits.

I've also written an article here, if you need more insight on why using lodash's cloneDeep.

You can't really compare NA with another value, so using == would not work. Consider the following:

NA == NA
# [1] NA

You can just change your comparison from == to %in%:

ifelse(is.na(test$time) | test$type %in% "A", NA, "1")
# [1] NA  "1" NA  "1"

Regarding your other question,

I could get this to work with my existing code if I could somehow change the result of is.na(test$type) to return FALSE instead of TRUE, but I'm not sure how to do that.

just use ! to negate the results:

!is.na(test$time)
# [1]  TRUE  TRUE FALSE  TRUE

Homebrew users: you can get lsusb by installing usbutils formula from my tap:

brew install mikhailai/misc/usbutils

It installs the REAL lsusb based on Linux sources (version 007).

To activate the installRelease task, you simply need a signingConfig. That is all.

From http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Android-tasks:

Finally, the plugin creates install/uninstall tasks for all build types (debug, release, test), as long as they can be installed (which requires signing).

Here is what you want:

Install tasks
-------------
installDebug - Installs the Debug build
installDebugTest - Installs the Test build for the Debug build
installRelease - Installs the Release build
uninstallAll - Uninstall all applications.
uninstallDebug - Uninstalls the Debug build
uninstallDebugTest - Uninstalls the Test build for the Debug build
uninstallRelease - Uninstalls the Release build   <--- release

Here is how to obtain the installRelease task:

Example build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}

apply plugin: 'com.android.application'

android {
  compileSdkVersion 22
  buildToolsVersion '22.0.1'

  defaultConfig {
    applicationId 'demo'
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName '1.0'
  }

  signingConfigs {
      release {
          storeFile <file>
          storePassword <password>
          keyAlias <alias>
          keyPassword <password>
      }
  }

  buildTypes {
    release {
        signingConfig signingConfigs.release
    }
  }
}

You can use file -i file_name to check what exactly your original file format is.

Once you get that, you can do the following:

iconv -f old_format -t utf-8 input_file -o output_file

How is this different from the following?

This line of code here:

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));

constructs a new String object (i.e. a copy of oldString), while this line of code:

String newString = oldString;

declares a new variable of type java.lang.String and initializes it to refer to the same String object as the variable oldString.

Is there any scenario in which the two lines will have different outputs?

Absolutely:

String newString = oldString;
boolean isSameInstance = newString == oldString; // isSameInstance == true

vs.

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));
 // isSameInstance == false (in most cases)    
boolean isSameInstance = newString == oldString;

a_horse_with_no_name (see comment) is right of course. The equivalent of

String newString = new String(oldString.getBytes("UTF-8"), "UTF-8"));

is

String newString = new String(oldString);

minus the subtle difference wrt the encoding that Peter Lawrey explains in his answer.

Just in case this helps anyone else; this error can occur in Visual Studio if you have a View as the open tab, and that tab depends on a parameter.

Close the current view and start your application and the app will start 'Normally'; if you have a view open, Visual Studio interprets this as you want to run the current view.

.NET has two CLRs 2.0 and 4.0. CLR 2.0 works till .NET framework 3.5. CLR 4.0 works from .NET 4.0 onwards. Its possible that your solution is using a different CLR than your reference assemblies. In your local development environment, you might have both the CLRs and hence you did not faced any problem. However when you moved to deployment environments, they might have a single CLR only and you got this error.

If you have Multiple iFrames inside the page, then this script might be useful. I am asuming there is a specific value in the iFrame source which can be used to find the specific iFrame.

var iframes = document.getElementsByTagName('iframe');
var yourIframe = null
for(var i=0; i < iframes.length ;i++){
    var source =  iframes[i].attributes.src.nodeValue;
    if(source.indexOf('/yourSorce') > -1){
        yourIframe = iframes[i];
    }   
}
var iSource = yourIframe.attributes.src.nodeValue;
yourIframe.src = iSource;

Replace "/yourSource" with value you need.

That is for people who prefer to have the constant on the left side. In most cases having the constant on the left side will prevent NullPointerException to be thrown (or having another nullcheck). For example the String method equals does also a null check. Having the constant on the left, will keep you from writing the additional check. Which, in another way is also performed later. Having the null value on the left is just being consistent.

like:

 String b = null;
 "constant".equals(b);  // result to false
 b.equals("constant");  // NullPointerException
 b != null && b.equals("constant");  // result to false

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)  { /* STYLES GO HERE */}

iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) { /* STYLES GO HERE */}

iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) { /* STYLES GO HERE */ }

iPad 3 & 4 Media Queries

If you're looking to target only 3rd and 4th generation Retina iPads (or tablets with similar resolution) to add @2x graphics, or other features for the tablet's Retina display, use the following media queries.

Retina iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */ }

iPad 1 & 2 Media Queries

If you're looking to supply different graphics or choose different typography for the lower resolution iPad display, the media queries below will work like a charm in your responsive design!

iPad 1 & 2 in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (-webkit-min-device-pixel-ratio: 1){ /* STYLES GO HERE */}

iPad 1 & 2 in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 1)  { /* STYLES GO HERE */}

iPad 1 & 2 in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) 
and (-webkit-min-device-pixel-ratio: 1) { /* STYLES GO HERE */ }

I think some explanation of Jon's answer would be constructive. The following:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

checks that if the specified file or directory respectively doesn't exist, then the rewrite rule proceeds:

RewriteRule ^(.*)\.html$ /$1 [L,R=301]

But what does that mean? It uses regex (regular expressions). Here is a little something I made earlier...

I think that's correct.

NOTE: When testing your .htaccess do not use 301 redirects. Use 302 until finished testing, as the browser will cache 301s. See https://stackoverflow.com/a/9204355/3217306

Update: I was slightly mistaken, . matches all characters except newlines, so includes whitespace. Also, here is a helpful regex cheat sheet

Sources:

http://community.sitepoint.com/t/what-does-this-mean-rewritecond-request-filename-f-d/2034/2

https://mediatemple.net/community/products/dv/204643270/using-htaccess-rewrite-rules

One possible solution would to use regex.

'phone' => 'required|regex:/(01)[0-9]{9}/'

This will check the input starts with 01 and is followed by 9 numbers. By using regex you don't need the numeric or size validation rules.

If you want to reuse this validation method else where, it would be a good idea to create your own validation rule for validating phone numbers.

Docs: Custom Validation

In your AppServiceProvider's boot method:

Validator::extend('phone_number', function($attribute, $value, $parameters)
{
    return substr($value, 0, 2) == '01';
});

This will allow you to use the phone_number validation rule anywhere in your application, so your form validation could be:

'phone' => 'required|numeric|phone_number|size:11'

In your validator extension you could also check if the $value is numeric and 11 characters long.

Another way this can be accomplished, and have not really seen any others give it as an option, is to instead use an anchor as a container around your input and label, and handle the removal of the label via some color trickory, the #hashtag, and the css a:visited. (jsfiddle at the bottom)

Your HTML would look like this:

<a id="Trickory" href="#OnlyHappensOnce">
    <input type="text" value="" id="email1" class="inputfield_ui" />
    <label>Email address 1</label>
</a>

And your CSS, something like this:

html, body {margin:0px}
a#Trickory {color: #CCC;} /* Actual Label Color */
a#Trickory:visited {color: #FFF;} /* Fake "Turn Off" Label */

a#Trickory:visited input {border-color: rgb(238, 238, 238);} /* Make Sure We Dont Mess With The Border Of Our Input */

a#Trickory input:focus + label {display: none;} /* "Turn Off" Label On Focus */

a#Trickory input {
    width:95%;
    z-index:3;
    position:relative;
    background-color:transparent;
}
a#Trickory label {
    position:absolute;
    pointer-events: none;
    display:block;
    top:3px;
    left:4px;
    z-index:1;
}

You can see this working over at jsfiddle, note that this solution only allows the user to select the field once, before it removes the label for good. Maybe not the solution you want, but definitely an available solution out there that I have not seen others mention. If you want to experiment multiple times, just change your #hashtag to a new 'non-visited' tag.

MVC doesn't do events. Just put a form and submit button on the page and the method decorated with the HttpPost attribute will process that request.

You might want to read a tutorial or two on how to create views, forms and controllers.

I had this issue and after hours of uninstalling and reinstalling I found out the issue in my instance.

The reason why I got this was down to the fact that I didn't have the correct extension.

In my case the ASP.net project (my startup) was the incompatible project and this was because I didn't have the following:

• Microsoft ASP.NET and Web Tools
• Micrsoft ASP.NET Web Frameworks and Tools

It was a simple case of going into extensions and updates under the Tools menu

you can use html entity as •

I solved this with this commands:

1- Run the container

# docker run -d <image-name>

2- List containers

   # docker ps -a

3- Use the container ID

# docker exec -it <container-id> /bin/sh

Follow these steps :

1. Create a project using the WSDL.
2. Choose your interface and open in interface viewer.
3. Navigate to the tab 'WSDL Content'.
4. Use the last icon under the tab 'WSDL Content' : 'Export the entire WSDL and included/imported files to a local directory'.
5. select the folder where you want the XSDs to be exported to.

Note: SOAPUI will remove all relative paths and will save all XSDs to the same folder. Refer the screenshot :

I'm using the environment variable COMPUTERNAME:

copy "C:\Program Files\Windows Resource Kits\Tools\" %SYSTEMROOT%\system32
srvcheck \\%COMPUTERNAME% > c:\shares.txt
echo %COMPUTERNAME%

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value=""></option>
    <option value="http://google.com">Google</option>
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

If your string is

foo="US/Central - 10:26 PM (CST)"

then

echo "${foo}" | cut -d ' ' -f3

will do the job.

you can pass multiple params in url like

http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc

and in order to get this query fields , you can use map like

    @RequestMapping(method = RequestMethod.GET, value = "/custom")
    public String controllerMethod(@RequestParam Map<String, String> customQuery) {

        System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
        System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
        System.out.println("customQuery = price " + customQuery.containsKey("price"));
        System.out.println("customQuery = other " + customQuery.containsKey("other"));
        System.out.println("customQuery = sort " + customQuery.containsKey("sort"));

        return customQuery.toString();
    }

You have a scope problem indeed, because statement is a local method variable defined here:

protected void createContents() {
    ...
    Statement statement = null; // local variable
    ...
     btnInsert.addMouseListener(new MouseAdapter() { // anonymous inner class
        @Override
        public void mouseDown(MouseEvent e) {
            ...
            try {
                statement.executeUpdate(query); // local variable out of scope here
            } catch (SQLException e1) {
                e1.printStackTrace();
            }
            ...
    });
}

When you try to access this variable inside mouseDown() method you are trying to access a local variable from within an anonymous inner class and the scope is not enough. So it definitely must be final (which given your code is not possible) or declared as a class member so the inner class can access this statement variable.

Sources:

• Anonymous Classes
• How are Anonymous (inner) classes used in Java?

How to solve it?

You could...

Make statement a class member instead of a local variable:

public class A1 { // Note Java Code Convention, also class name should be meaningful   
    private Statement statement;
    ...
}

You could...

Define another final variable and use this one instead, as suggested by @HotLicks:

protected void createContents() {
    ...
    Statement statement = null;
    try {
        statement = connect.createStatement();
        final Statement innerStatement = statement;
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    ...
}

But you should...

Reconsider your approach. If statement variable won't be used until btnInsert button is pressed then it doesn't make sense to create a connection before this actually happens. You could use all local variables like this:

btnInsert.addMouseListener(new MouseAdapter() {
   @Override
   public void mouseDown(MouseEvent e) {
       try {
           Class.forName("com.mysql.jdbc.Driver");
           try (Connection connect = DriverManager.getConnection(...);
                Statement statement = connect.createStatement()) {

                // execute the statement here

           } catch (SQLException ex) {
               ex.printStackTrace();
           }

       } catch (ClassNotFoundException ex) {
           e.printStackTrace();
       }
});

I would recommend adding headers for the same. Moving metadata to headers helps in getting rid of envelops like result , data or records and response body only contains the data we need. You can use Link header if you generate pagination links too.

    HTTP/1.1 200
    Pagination-Count: 100
    Pagination-Page: 5
    Pagination-Limit: 20
    Content-Type: application/json

    [
      {
        "id": 10,
        "name": "shirt",
        "color": "red",
        "price": "$23"
      },
      {
        "id": 11,
        "name": "shirt",
        "color": "blue",
        "price": "$25"
      }
    ]

For swagger file:

Your .gitignore file should look like this:

# Ignore Mac DS_Store files
.DS_Store

As long as you don't include a slash, it is matched against the file name in all directories. (from here)

I hit similar issue - in my case Source contained <, > characters. 64 bit machines are using new even log - xml base I would say and these characters (set from string) create invalid xml which causes exception. Arguably this should be consider Microsoft issue - not handling the Source (name/string) correctly.

Another possibility only present in comments yet:

Map<String, Choice> result =
choices.stream().collect(Collectors.toMap(c -> c.getName(), c -> c)));

Useful if you want to use a parameter of a sub-object as Key:

Map<String, Choice> result =
choices.stream().collect(Collectors.toMap(c -> c.getUser().getName(), c -> c)));

If you append ..\.. to your existing path, the operating system will correctly browse the grand-parent folder.

That should do the job:

System.IO.Path.Combine("C:\\Users\\Masoud\\Documents\\Visual Studio 2008\\Projects\\MyProj\\MyProj\\bin\\Debug", @"..\..");

If you browse that path, you will browse the grand-parent directory.

/* This is not the proper way, this is a solution for older devices that run Android 4.0 or older. This can be used for testing purposes, but not recommended for main development.

This one can also be used with less effort I believe (but I am in MVC 5)

@Html.Description(model => model.Story, 20, 50, new { })

(I've lightly modified the identifiers as fixed-width names aren't representative of real code – at least not real code that I encounter – and will belie an example's readability.)

if (cond1 == "val1" and cond22 == "val2"
and cond333 == "val3" and cond4444 == "val4"):
    do_something

This works well for "and" and "or" (it's important that they're first on the second line), but much less so for other long conditions. Fortunately, the former seem to be the more common case while the latter are often easily rewritten with a temporary variable. (It's usually not hard, but it can be difficult or much less obvious/readable to preserve the short-circuiting of "and"/"or" when rewriting.)

Since I found this question from your blog post about C++, I'll include that my C++ style is identical:

if (cond1 == "val1" and cond22 == "val2"
and cond333 == "val3" and cond4444 == "val4") {
    do_something
}

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

tf.nn.softmax computes the forward propagation through a softmax layer. You use it during evaluation of the model when you compute the probabilities that the model outputs.

tf.nn.softmax_cross_entropy_with_logits computes the cost for a softmax layer. It is only used during training.

The logits are the unnormalized log probabilities output the model (the values output before the softmax normalization is applied to them).

There are two operators for type testing: E is T tests for E an instance of type T while E is! T tests for E not an instance of type T.

Note that E is Object is always true, and null is T is always false unless T===Object.

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

With Swift 5 this is what, worked for me!!

Step 1. Created IBOutlet for UIButton in My CustomCell.swift

class ListProductCell: UITableViewCell {
@IBOutlet weak var productMapButton: UIButton!
//todo
}

Step 2. Added action method in CellForRowAtIndex method and provided method implementation in the same view controller

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ListProductCell") as! ListProductCell
cell.productMapButton.addTarget(self, action: #selector(ListViewController.onClickedMapButton(_:)), for: .touchUpInside)
return cell
    }

@objc func onClickedMapButton(_ sender: Any?) {

        print("Tapped")
    }

In general, that depends on your shell, but if you use bash, zsh, ksh or sh (as provided by dash), the following should work:

if ! type "$foobar_command_name" > /dev/null; then
  # install foobar here
fi

For a real installation script, you'd probably want to be sure that type doesn't return successfully in the case when there is an alias foobar. In bash you could do something like this:

if ! foobar_loc="$(type -p "$foobar_command_name")" || [[ -z $foobar_loc ]]; then
  # install foobar here
fi

The short answer:

Use the click event, which won't fire until after the value has been updated, and fires when you want it to:

<label><input type='checkbox' onclick='handleClick(this);'>Checkbox</label>

function handleClick(cb) {
  display("Clicked, new value = " + cb.checked);
}

Live example | Source

The longer answer:

The change event handler isn't called until the checked state has been updated (live example | source), but because (as Tim Büthe points out in the comments) IE doesn't fire the change event until the checkbox loses focus, you don't get the notification proactively. Worse, with IE if you click a label for the checkbox (rather than the checkbox itself) to update it, you can get the impression that you're getting the old value (try it with IE here by clicking the label: live example | source). This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing.

But you can avoid all of that unpleasantness if you use click instead.

I've used DOM0 handlers (onxyz attributes) because that's what you asked about, but for the record, I would generally recommend hooking up handlers in code (DOM2's addEventListener, or attachEvent in older versions of IE) rather than using onxyz attributes. That lets you attach multiple handlers to the same element and lets you avoid making all of your handlers global functions.

An earlier version of this answer used this code for handleClick:

function handleClick(cb) {
  setTimeout(function() {
    display("Clicked, new value = " + cb.checked);
  }, 0);
}

The goal seemed to be to allow the click to complete before looking at the value. As far as I'm aware, there's no reason to do that, and I have no idea why I did. The value is changed before the click handler is called. In fact, the spec is quite clear about that. The version without setTimeout works perfectly well in every browser I've tried (even IE6). I can only assume I was thinking about some other platform where the change isn't done until after the event. In any case, no reason to do that with HTML checkboxes.

I ran into a real problem where it was indeed evil. Essentially a developer returned a reference to an object in a vector. That was Bad!!!

The full details I wrote about in Janurary: http://developer-resource.blogspot.com/2009/01/pros-and-cons-of-returing-references.html

No need to use select just use [ instead

data[,grepl("search_string", colnames(data))]

Let's try with iris dataset

>iris[,grepl("Sepal", colnames(iris))]
  Sepal.Length Sepal.Width
1          5.1         3.5
2          4.9         3.0
3          4.7         3.2
4          4.6         3.1
5          5.0         3.6
6          5.4         3.9

The lock statement is translated to calls to the Enter and Exit methods of Monitor.

The lock statement will wait indefinitely for the locking object to be released.

For the sake of snippet of what the guys have explained above:

import socket
from contextlib import closing

def find_free_port():
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as s:
        s.bind(('', 0))
        s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        return s.getsockname()[1]

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

I found this to work for me:

iconv -f ISO-8859-14 Agreement.txt -t UTF-8 -o agreement.txt

TASK:

Let's consider the following example:

if (!answer.isSuccessful()) {
    result = "wrong"
} else {
    result = answer.body().string()
}
return result

We need the following equivalent in Kotlin:

return ( !answer.isSuccessful() ) ? "wrong" : answer.body().string()

SOLUTION 1.a. You can use if-expression in Kotlin:

return if (!answer.isSuccessful()) "wrong" else answer.body().string()

SOLUTION 1.b. It can be much better if you flip this if-expression (let's do it without not):

return if (answer.isSuccessful()) answer.body().string() else "wrong"

SOLUTION 2. Kotlin’s Elvis operator ?: can do a job even better:

return answer.body()?.string() ?: "wrong"

SOLUTION 3. Or use an Extension function for the corresponding Answer class:

fun Answer.bodyOrNull(): Body? = if (isSuccessful()) body() else null

SOLUTION 4. Using the Extension function you can reduce a code thanks to Elvis operator:

return answer.bodyOrNull()?.string() ?: "wrong"

SOLUTION 5. Or just use when operator:

when (!answer.isSuccessful()) {
    parseInt(str) -> result = "wrong"
    else -> result = answer.body().string()
}

Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.

Writing that much data to a file is going to take a while.

You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).

You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?

You should also write a function to do the calculation; you could use an inline function in C99 or later (or C++). The repetition in the code is excruciating to behold.

You should also use C99 notation for main(), with the explicit return type (and preferably void for the argument list when you are not using argc or argv):

int main(void)

Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 }; (thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static in front of the functions, and the main array; file becomes a local to main; error check the fopen(), etc.).

I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.

#include <stdio.h>

#define   lambda   2.0
#define   g        1.0
#define   F0       1.0
#define   h        0.1
#define   e        0.00001

enum { ROWS = 1000, COLS = 10000 };

static double F[ROWS][COLS];

static void Inicio(double D[ROWS][COLS])
{
    for (int i = 399; i < 600; i++) // Magic numbers!!
        D[i][0] = F0;
}

enum { R = ROWS - 1 };

static inline int ko(int k, int n)
{
    int rv = k + n;
    if (rv >= R)
        rv -= R;
    else if (rv < 0)
        rv += R;
    return(rv);
}

static inline void calculate_value(int i, int k, double A[ROWS][COLS])
{
    int ks2 = ko(k, -2);
    int ks1 = ko(k, -1);
    int kp1 = ko(k, +1);
    int kp2 = ko(k, +2);

    A[k][i] = A[k][i-1]
            + e/(h*h*h*h) * g*g * (A[kp2][i-1] - 4.0*A[kp1][i-1] + 6.0*A[k][i-1] - 4.0*A[ks1][i-1] + A[ks2][i-1])
            + 2.0*g*e/(h*h) * (A[kp1][i-1] - 2*A[k][i-1] + A[ks1][i-1])
            + e * A[k][i-1] * (lambda - A[k][i-1] * A[k][i-1]);
}

static void Iteration(double A[ROWS][COLS])
{
    for (int i = 1; i < COLS; i++)
    {
        for (int k = 0; k < R; k++)
            calculate_value(i, k, A);
        A[999][i] = A[0][i];
    }
}

int main(void)
{
    FILE *file = fopen("P2.txt","wt");
    if (file == 0)
        return(1);
    Inicio(F);
    Iteration(F);
    for (int i = 0; i < COLS; i++)
    {
        for (int j = 0; j < ROWS; j++)
        {
            fprintf(file,"%lf \t %.4f \t %lf\n", 1.0*j/10.0, 1.0*i, F[j][i]);
        }
    }
    fclose(file);
    return(0);
}

This program writes to P2.txt instead of P1.txt. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for loop became:

for (int i = COLS - 1; i < COLS; i++)

the timings were vastly reduced and very much more consistent:

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.

      new AsyncRoute({path: '/demo/:demoKey1/:demoKey2', loader: () => {
      return System.import('app/modules/demo/demo').then(m =>m.demoComponent);
       }, name: 'demoPage'}),
       export class demoComponent {
       onClick(){
            this._router.navigate( ['/demoPage', {demoKey1: "123", demoKey2: "234"}]);
          }
        }

I don't know if javaw will write to the %errorlevel% variable, but it might.

echo %errorlevel% after you run it directly to see.

Other than that, you can pipe the output of javaw to a file, then use find to see what the results were. Without knowing the output of it, I can't really help you with that.

If you are using an IDE, go to run, edit configurations, gradle, select gradle task and update the environment variables. See the picture below.

Alternatively, if you are executing gradle commands using terminal, just type 'export KEY=VALUE', and your job is done.

The .clone() thing does not work in Opera (and possibly others). It keeps the content.

The closest method here for me was Jonathan's earlier, however ensuring that the field preserved its name, classes, etc made for messy code in my case.

Something like this might work well (thanks to Quentin too):

function clearInput($source) {
    var $form = $('<form>')
    var $targ = $source.clone().appendTo($form)
    $form[0].reset()
    $source.replaceWith($targ)
}

It's work for Iphone

<?php
  $browser = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
  if ($browser == true){
    $browser = 'iphone';
  }
?>

You can use the following code to both work with the command line and a web browser. Put this code above your PHP code. It creates a $_GET variable for each command line parameter.

In your code you only need to check for $_GET variables then, not worrying about if the script is called from the web browser or command line.

if(isset($argv))
    foreach ($argv as $arg) {
        $e=explode("=",$arg);
        if(count($e)==2)
            $_GET[$e[0]]=$e[1];
        else
            $_GET[$e[0]]=0;
    }

I've always tested to find the MAX string length of an encrypted string and set that as the character length of a VARCHAR type. Depending on how many records you're going to have, it could really help the database size.

This page contains all the cached urls

chrome://cache

Unfortunately to actually see the file you have to select everything on the page and paste it in this tool: http://www.sensefulsolutions.com/2012/01/viewing-chrome-cache-easy-way.html

The name of the DOM function is actually getElementsByClassName, not getElementByClassName, simply because more than one element on the page can have the same class, hence: Elements.

The return value of this will be a NodeList instance, or a superset of the NodeList (FF, for instance returns an instance of HTMLCollection). At any rate: the return value is an array-like object:

var y = document.getElementsByClassName('foo');
var aNode = y[0];

If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:

var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);

As yckart suggested querySelector('.foo') and querySelectorAll('.foo') would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:

• querySelector(all)
• getElementsByClassName
• Don't use w3schools to learn something
• Refer to MDN for accurate information

If you have (or create) a single string, you can use np.fromstring:

import numpy as np
x = ["1.1", "2.2", "3.2"]
x = ','.join(x)
x = np.fromstring( x, dtype=np.float, sep=',' )

Note, x = ','.join(x) transforms the x array to string '1.1, 2.2, 3.2'. If you read a line from a txt file, each line will be already a string.

just delete the app and try again, it happens to me when i try to launch over a device that has the same app but generated by an ipa file.

I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.

ul li{
text-indent: -1em;
}

If you want to present it modally, you should have something like bellow:

let vc = self.storyboard!.instantiateViewControllerWithIdentifier("YourViewControllerID")
self.showDetailViewController(vc as! YourViewControllerClassName, sender: self)

Most of these answers circulate around removing a file from the "staging area" pre-commit, but I often find myself looking here after I've already committed and I want to remove some sensitive information from the commit I just made.

An easy to remember trick for all of you git commit --amend folks out there like me is that you can:

1. Delete the accidentally committed file.
2. git add . to add the deletion to the "staging area"
3. git commit --amend to remove the file from the previous commit.

You will notice in the commit message that the unwanted file is now missing. Hooray! (Commit SHA will have changed, so be careful if you already pushed your changes to the remote.)

Not the perfect answer but works better for people using Github:

Go to your repo: Insights -> Network

This is a follow up to my original question to help out others with the same problem. If you need to filter by an attribute, rather than manually looking up the id you can use the following code to retrieve all the id, value pairs for an attribute. The data is returned as an array with the attribute name as the key.

function getAttributeOptions($attributeName) {
    $product = Mage::getModel('catalog/product');
    $collection = Mage::getResourceModel('eav/entity_attribute_collection')
              ->setEntityTypeFilter($product->getResource()->getTypeId())
              ->addFieldToFilter('attribute_code', $attributeName);

    $_attribute = $collection->getFirstItem()->setEntity($product->getResource());
    $attribute_options  = $_attribute->getSource()->getAllOptions(false);
    foreach($attribute_options as $val) {
        $attrList[$val['label']] = $val['value'];
    }   

    return $attrList;
}

Here is a function you can use to get products by their attribute set id. Retrieved using the previous function.

function getProductsByAttributeSetId($attributeSetId) {
   $products = Mage::getModel('catalog/product')->getCollection();
   $products->addAttributeToFilter('attribute_set_id',$attributeSetId);

   $products->addAttributeToSelect('*');

   $products->load();
   foreach($products as $val) {
     $productsArray[] = $val->getData();
  }

  return $productsArray;
}

Server restart helped, I'm able to connect to server again.

You can do it by using GeometryReader

GeometryReader

Code:

struct ContentView : View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
               Text("Turtle Rock").frame(width: geometry.size.width, height: geometry.size.height, alignment: .topLeading).background(Color.red)
            }
        }
    }
}

Your output like:

How about something like

git log --pretty=oneline master > 1
git log --pretty=oneline branch_A > 2

git rev-parse `diff 1 2 | tail -1 | cut -c 3-42`^

Importing the namespace is somewhat cleaner. Imagine you have two different modules you import, both of them with the same method/class. Some bad stuff might happen. I'd dare say it is usually good practice to use:

import module

over

from module import function/class

For counting a character in a string you have to use YOUR_VARIABLE.count('WHAT_YOU_WANT_TO_COUNT').

If summarization is needed you have to use count() function.

variable = 'turkiye'
print(variable.count('u'))

output: 1

I was also confused as to why we're adding a cmd at the beginning and I was wondering if I had to open the command prompt first. What you need to do is type the full command along with cmd /k. For example assume your batch file name is "my_command.bat" which runs the command javac my_code.java then the code in your batch file should be:

cmd /k javac my_code.java

So basically there is no need to open command prompt at the current folder and type the above command but you can save this code directly in your batch file and execute it directly.

The \caption command is restricted to floats: you will need to place the equation in a figure or table environment (or a new kind of floating environment). For example:

\begin{figure}
\[ E = m c^2 \]
\caption{A famous equation}
\end{figure}

The point of floats is that you let LaTeX determine their placement. If you want to equation to appear in a fixed position, don't use a float. The \captionof command of the caption package can be used to place a caption outside of a floating environment. It is used like this:

\[ E = m c^2 \]
\captionof{figure}{A famous equation}

This will also produce an entry for the \listoffigures, if your document has one.

To align parts of an equation, take a look at the eqnarray environment, or some of the environments of the amsmath package: align, gather, multiline,...

You could try:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.ToArray());

Not sure if .ToArray() is available for the collection. If you do use the code you posted, make sure you initialize the List with the number of existing elements:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.Count);  // or .Length

Disclaimer: I work for a company, Particle Code, that makes a cross-platform framework. There are a ton of companies in this space. New ones seem to spring up every week. Good news for you: you have a lot of choices.

These frameworks take different approaches, and many of them are fundamentally designed to solve different problems. Some are focused on games, some are focused on apps. I would ask the following questions:

What do you want to write? Enterprise application, personal productivity application, puzzle game, first-person shooter?

What kind of development environment do you prefer? IDE or plain ol' text editor?

Do you have strong feelings about programming languages? Of the frameworks I'm familiar with, you can choose from ActionScript, C++, C#, Java, Lua, and Ruby.

My company is more in the game space, so I haven't played as much with the JavaScript+CSS frameworks like Titanium, PhoneGap, and Sencha. But I can tell you a bit about some of the games-oriented frameworks. Games and rich internet applications are an area where cross-platform frameworks can shine, because these applications tend to place more importance of being visually unique and less on blending in with native UIs. Here are a few frameworks to look for:

• Unity www.unity3d.com is a 3D games engine. It's really unlike any other development environment I've worked in. You build scenes with 3D models, and define behavior by attaching scripts to objects. You can script in JavaScript, C#, or Boo. If you want to write a 3D physics-based game that will run on iOS, Android, Windows, OS X, or consoles, this is probably the tool for you. You can also write 2D games using 3D assets--a fine example of this is indie game Max and the Magic Marker, a 2D physics-based side-scroller written in Unity. If you don't know it, I recommend checking it out (especially if there are any kids in your household). Max is available for PC, Wii, iOS and Windows Phone 7 (although the latter version is a port, since Unity doesn't support WinPhone). Unity comes with some sample games complete with 3D assets and textures, which really helps getting up to speed with what can be a pretty complicated environment.

• Corona www.anscamobile.com/corona is a 2D games engine that uses the Lua scripting language and supports iOS and Android. The selling point of Corona is the ability to write physics-based games very quickly in few lines of code, and the large number of Corona-based games in the iOS app store is a testament to its success. The environment is very lean, which will appeal to some people. It comes with a simulator and debugger. You add your text editor of choice, and you have a development environment. The base SDK doesn't include any UI components, like buttons or list boxes, but a CoronaUI add-on is available to subscribers.

• The Particle SDK www.particlecode.com is a slightly more general cross-platform solution with a background in games. You can write in either Java or ActionScript, using a MVC application model. It includes an Eclipse-based IDE with a WYSIWYG UI editor. We currently support building for Android, iOS, webOS, and Windows Phone 7 devices. You can also output Flash or HTML5 for the web. The framework was originally developed for online multiplayer social games, such as poker and backgammon, and it suits 2D games and apps with complex logic. The framework supports 2D graphics and includes a 2D physics engine.

NB:

_{Today we announced that Particle Code has been acquired by Appcelerator, makers of the Titanium cross-platform framework.}

_...

_{As of January 1, 2012, [Particle Code] will no longer officially support the [Particle SDK] platform.}

• The Airplay SDK www.madewithmarmalade.com is a C++ framework that lets you develop in either Visual Studio or Xcode. It supports both 2D and 3D graphics. Airplay targets iOS, Android, Bada, Symbian, webOS, and Windows Mobile 6. They also have an add-on to build AirPlay apps for PSP. My C++ being very rusty, I haven't played with it much, but it looks cool.

In terms of learning curve, I'd say that Unity had the steepest learning curve (for me), Corona was the simplest, and Particle and Airplay are somewhere in between.

Another interesting point is how the frameworks handle different form factors. Corona supports dynamic scaling, which will be familiar to Flash developers. This is very easy to use but means that you end up wasting screen space when going from a 4:3 screen like the iPhone to a 16:9 like the new qHD Android devices. The Particle SDK's UI editor lets you design flexible layouts that scale, but also lets you adjust the layouts for individual screen sizes. This takes a little more time but lets you make the app look custom made for each screen.

Of course, what works for you depends on your individual taste and work style as well as your goals -- so I recommend downloading a couple of these tools and giving them a shot. All of these tools are free to try.

Also, if I could just put in a public service announcement -- most of these tools are in really active development. If you find a framework you like, by all means send feedback and let them know what you like, what you don't like, and features you'd like to see. You have a real opportunity to influence what goes into the next versions of these tools.

Hope this helps.

Pass the correct arguments? :P

On the more serious note, you can pass the argument -Wi::DeprecationWarning on the command line to the interpreter to ignore the deprecation warnings.

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

I have faced similar problem and it was returning #N/A. That means matching data is present but you might having extra space in the M3 column record, that may prevent it from getting exact value. Because you have set last parameter as FALSE, it is looking for "exact match". This formula is correct: =VLOOKUP(M3,Sheet1!$A$2:$Q$47,13,FALSE)

Sadly, as of this writing, DESPITE their own documentation readme, there is no src.zip in the JDK 7 or 8 install directories when you download the Windows version.

Note: perhaps this happens because many of us don't actually run the install .exe, but instead extract it. Many of us don't run the Java install (the full blown windows install) for security reasons....we just want the JDK put someplace out of the way where potential viruses cannot find it.

But their policy regarding the windows .exe (whatever it truly is) is indeed nuts, HOWEVER, the src.zip DOES exist in the linux install (a .tar.gz). There are multiple ways of extracting a .tar and a .gz, and I prefer the free "7Zip" utility.

1. download the Linux 64 bit .tar.gz
2. use 7zip to uncompress the .tar.gz to a .tar
3. use 7zip to extract the .tar to the installation directory
4. src.zip will be waiting for you in that installation directory.
5. pull it out and place it where you like.

Oracle, this is really beyond stupid.

object-fit: cover will do exactly what you need.

But it might not work on IE/Edge. Follow as shown below to fix it with just CSS to work on all browsers.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Once it is in the centre, I give to the image,

// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;

// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;

This makes the image get the effect of Object-fit:cover.

Here is a demonstration of the above logic.

https://jsfiddle.net/furqan_694/s3xLe1gp/

This logic works in all browsers.

Original Image

Vertically Cropped

Horizontally Cropped

An object is only once in memory. Your first addition to list just adds the object references.

anotherList.addAll will also just add the references. So still only 100 objects in memory.

If you change list by adding/removing elements, anotherList won't be changed. But if you change any object in list, then it's content will be also changed, when accessing it from anotherList, because the same reference is being pointed to from both lists.

You may also try this jQuery plugin: https://github.com/morr/jquery.appear

BufferedReader in = new BufferedReader(new InputStreamReader(
        new GZIPInputStream(new FileInputStream("F:/gawiki-20090614-stub-meta-history.xml.gz"))));

String content;

while ((content = in.readLine()) != null)

   System.out.println(content);

You can also have a look at FLTK (C++ and not plain C though)

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Here are some quickstart screencasts

[Happy New Year!]

If your tld's are on the classpath, typically under the WEB-INF directory, the following two tips should resolve the issue (irrespective of your environment setup):

1. Ensure that the <uri> in the TLD and the uri in the taglib directive of your jsp pages match. The <uri> element of the tld is a unique name for the tag library.

2. If the tld does not have a <uri> element, the Container will attempt to use the uri attribute in the taglib directive as a path to the actual TLD. for e.g. I could have a custom tld file in my WEB-INF folder and use the path to the this tld as the uri value in my JSP. However, this is a bad practice and should be avoided since the paths would then be hardcoded.

One of the most straightforward ways to do it is

git for-each-ref --format='%(refname:short)' refs/heads/

This works perfectly for scripts as well.

Unfortunately, IE and VLC don't really work right now... I found this on the vlc forums:

VLC included activex support up until version 0.8.6, I believe. At that time, you could
access a cab on the videolan and therefore 'automatic' installation into IE and Firefox
family browsers was fine. Thereafter support for activex seemed to stop; no cab, no
activex component.

VLC 1.0.* once again contains activex support, and that's brilliant. A good decision in
my opinion. What's lacking is a cab installer for the latest version.

This basically means that even if you found a way to make it work, anyone trying to view the video on your site in IE would have to download and install the entire VLC player program to have it work in IE, and users probably don't want to do that. I can't get your code to work in firefox or IE8 on my boyfriends computer, although I might not have been putting the video address in properly... I get some message about no video output...

I'll take a guess and say it probably works for you locally because you have VLC installed, but your server doesn't. Unfortunately you'll probably have to use Windows media player or something similar (Microsoft is great at forcing people to use their stuff!)

And if you're wondering, it appears that the reason there is no cab file is because of the cost of having an active-x control signed.

It's rather simple to have your page use VLC for firefox and chrome users, and Windows Media Player for IE users, if that would work for you.

<form id="myform">
    <input type="textbox" id="field"/>
    <input type="button" value="submit">
</form>

<script>
    $(function () {
        $("#field").keyup(function (event) {
            if (event.which === 13) {
                document.myform.submit();
            }
        }
    });
</script>

The problem is the indexing subplot is using. Subplots are counted starting with 1! Your code thus needs to read

fig=plt.figure(figsize=(15, 6),facecolor='w', edgecolor='k')
for i in range(10):

    #this part is just arranging the data for contourf 
    ind2 = py.find(zz==i+1)
    sfr_mass_mat = np.reshape(sfr_mass[ind2],(pixmax_x,pixmax_y))
    sfr_mass_sub = sfr_mass[ind2]
    zi = griddata(massloclist, sfrloclist, sfr_mass_sub,xi,yi,interp='nn')


    temp = 251+i  # this is to index the position of the subplot
    ax=plt.subplot(temp)
    ax.contourf(xi,yi,zi,5,cmap=plt.cm.Oranges)
    plt.subplots_adjust(hspace = .5,wspace=.001)

    #just annotating where each contour plot is being placed
    ax.set_title(str(temp))

Note the change in the line where you calculate temp

The derivedFactor function from mosaic package seems to be designed to handle this. Using this example, it would look like:

library(dplyr)
library(mosaic)
df <- mutate(df, g = derivedFactor(
     "2" = (a == 2 | a == 5 | a == 7 | (a == 1 & b == 4)),
     "3" = (a == 0 | a == 1 | a == 4 | a == 3 |  c == 4),
     .method = "first",
     .default = NA
     ))

(If you want the result to be numeric instead of a factor, you can wrap derivedFactor in an as.numeric call.)

derivedFactor can be used for an arbitrary number of conditionals, too.

I suggest using one of the exchange methods that accepts an HttpEntity for which you can also set the HttpHeaders. (You can also specify the HTTP method you want to use.)

For example,

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));

HttpEntity<String> entity = new HttpEntity<>("body", headers);

restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

I prefer this solution because it's strongly typed, ie. exchange expects an HttpEntity.

However, you can also pass that HttpEntity as a request argument to postForObject.

HttpEntity<String> entity = new HttpEntity<>("body", headers);
restTemplate.postForObject(url, entity, String.class); 

This is mentioned in the RestTemplate#postForObject Javadoc.

The request parameter can be a HttpEntity in order to add additional HTTP headers to the request.

You could also give them all the same name so they are an array, but give them different values:

<div id="checkboxes">
    <input type="checkbox" name="c_n[]" value="c_n_0" checked="checked" />Option 1
    <input type="checkbox" name="c_n[]" value="c_n_1" />Option 2
    <input type="checkbox" name="c_n[]" value="c_n_2" />Option 3
    <input type="checkbox" name="c_n[]" value="c_n_3" checked="checked" />Option 4
</div>

You can then get only the value of only the ticked ones using map:

$('#checkboxes input:checked[name="c_n[]"]')
            .map(function () { return $(this).val(); }).get()

Use numeric(n,n) where n has enough resolution to round to 1.00. For instance:

declare @discount numeric(9,9)
    , @quantity int
select @discount = 0.999999999
    , @quantity = 10000

select convert(money, @discount * @quantity)

I suspect ^ doesn't work the way you think it does outside of a character class.

What you're telling it to do is replace everything that isn't an alphanumeric with an empty string, OR any leading space. I think what you mean to say is that spaces are ok to not replace - try moving the \s into the [] class.

I had this problem when I try to write a very long url, the following works.

image_url = %w(
    http://minio.127.0.0.1.xip.io:9000/
    bucket29/docs/b7cfab0e-0119-452c-b262-1b78e3fccf38/
    28ed3774-b234-4de2-9a11-7d657707f79c?
    X-Amz-Algorithm=AWS4-HMAC-SHA256&
    X-Amz-Credential=ABABABABABABABABA
    %2Fus-east-1%2Fs3%2Faws4_request&
    X-Amz-Date=20170702T000940Z&
    X-Amz-Expires=3600&X-Amz-SignedHeaders=host&
    X-Amz-Signature=ABABABABABABABABABABAB
    ABABABABABABABABABABABABABABABABABABA
).join

Note, there must not be any newlines, white spaces when the url string is formed. If you want newlines, then use HEREDOC.

Here you have indentation for readability, ease of modification, without the fiddly quotes and backslashes on every line. The cost of joining the strings should be negligible.

Update Nevermind, this doesn't work in IE or it's new brother, FF. Works on every other type of element as expected, but doesn't work on file inputs. A much better way to do this is to just create a file input and a label that links to it. Make the file input display none and boom, it works in IE9+ seamlessly.

Warning: Everything below this is crap!

By using pseudo elements positioned/sized against their container, we can get by with only one input file (no additional markup needed), and style as per usual.

Demo

<input type="file" class="foo">

.foo {
    display: block;
    position: relative;
    width: 300px;
    margin: auto;
    cursor: pointer;
    border: 0;
    height: 60px;
    border-radius: 5px;
    outline: 0;
}
.foo:hover:after {
    background: #5978f8;
}
.foo:after {
    transition: 200ms all ease;
    border-bottom: 3px solid rgba(0,0,0,.2);
    background: #3c5ff4;
    text-shadow: 0 2px 0 rgba(0,0,0,.2);
    color: #fff;
    font-size: 20px;
    text-align: center;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: block;
    content: 'Upload Something';
    line-height: 60px;
    border-radius: 5px;
}

Enjoy guys!

Old Update

Turned this into a Stylus mixin. Should be easy enough for one of you cool SCSS cats to convert it.

file-button(button_width = 150px)
  display block

  outline none
  &:after
    position absolute
    top 0
    text-align center

A bit like what @Hossein Hajizadeh alerady said, though in more detail:

There is an alternative to eval().

The function setTimeout() is designed to execute something after an interval of milliseconds, and the code to be executed just so happens to be formatted as a string.

It would work like this:

ExecuteJavascriptString(); //Just for running it_x000D_
_x000D_
function ExecuteJavascriptString()_x000D_
{_x000D_
    var s = "alert('hello')";_x000D_
    setTimeout(s, 1);_x000D_
}

1 means it will wait 1 millisecond before executing the string.

It might not be the most correct way to do it, but it works.

I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.

I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:

    $('.start').keyup(function() {
        var otherInputs = $(this).parents('td').siblings().find('input');

        for(var i = 0; i < otherInputs.length; i++) {
            alert($(otherInputs[i]).val());
        }
        return false;
    });

This bash script is for N parallel threads. Each argument is a command.

trap will kill all subprocesses when SIGINT is catched.
wait $PID_LIST is waiting each process to complete. When all processes have completed, the program exits.

#!/bin/bash

for cmd in "$@"; do {
  echo "Process \"$cmd\" started";
  $cmd & pid=$!
  PID_LIST+=" $pid";
} done

trap "kill $PID_LIST" SIGINT

echo "Parallel processes have started";

wait $PID_LIST

echo
echo "All processes have completed";

Save this script as parallel_commands and make it executable.
This is how to use this script:

parallel_commands "cmd arg0 arg1 arg2" "other_cmd arg0 arg2 arg3"

Example:

parallel_commands "sleep 1" "sleep 2" "sleep 3" "sleep 4"

Start 4 parallel sleep and waits until "sleep 4" finishes.

React events are actually Synthetic Events, not Native Events. As it is written here:

Event delegation: React doesn't actually attach event handlers to the nodes themselves. When React starts up, it starts listening for all events at the top level using a single event listener. When a component is mounted or unmounted, the event handlers are simply added or removed from an internal mapping. When an event occurs, React knows how to dispatch it using this mapping. When there are no event handlers left in the mapping, React's event handlers are simple no-ops.

Try to use Use Event.stopImmediatePropagation:

upvote: (e) ->
  e.stopPropagation();
  e.nativeEvent.stopImmediatePropagation();

The </script> inside the Javascript string litteral is interpreted by the HTML parser as a closing tag, causing unexpected behaviour (see example on JSFiddle).

To avoid this, you can place your javascript between comments (this style of coding was common practice, back when Javascript was poorly supported among browsers). This would work (see example in JSFiddle):

<script type="text/javascript">
    <!--
    if (jQuery === undefined) {
        document.write('<script type="text/javascript" src="http://z-ecx.images-amazon.com/images/G/01/javascripts/lib/jquery/jquery-1.2.6.pack._V265113567_.js"></script>');
    }
    // -->
</script>

...but to be honest, using document.write is not something I would consider best practice. Why not manipulating the DOM directly?

<script type="text/javascript">
    <!--
    if (jQuery === undefined) {
        var script = document.createElement('script');
        script.setAttribute('type', 'text/javascript');
        script.setAttribute('src', 'http://z-ecx.images-amazon.com/images/G/01/javascripts/lib/jquery/jquery-1.2.6.pack._V265113567_.js');
        document.body.appendChild(script);
    }
    // -->
</script>

h = ['a','b','c','d','e','f']
g = ''
for f in h:
    g = g + f

>>> g
'abcdef'

In my case, it ended up being a simple double quote issue in my bookmarklet, remember only use single quotes on bookmarklets. Just in case this helps someone.

nice one line alternative

element.addEventListener('dragstart',(evt) => onDragStart(param1, param2, param3, evt));

function onDragStart(param1, param2, param3, evt) {

 //some action...

}

For anybody interested in Titanium i must say that they don't have a very good documentation some classes, properties, methods are missing. But a lot is "documented" in their sample app the KitchenSink so it is not THAT bad.

I came here looking for a simple 1-liner to remove/correct the identation level of the docstring for printing, without making it look untidy, for example by making it "hang outside the function" within the script.

Here's what I ended up doing:

import string
def myfunction():

    """
    line 1 of docstring
    line 2 of docstring
    line 3 of docstring"""

print str(string.replace(myfunction.__doc__,'\n\t','\n'))[1:] 

Obviously, if you're indenting with spaces (e.g. 4) rather than the tab key use something like this instead:

print str(string.replace(myfunction.__doc__,'\n    ','\n'))[1:]

And you don't need to remove the first character if you like your docstrings to look like this instead:

    """line 1 of docstring
    line 2 of docstring
    line 3 of docstring"""

print string.replace(myfunction.__doc__,'\n\t','\n') 

.icon{
background: url(1.jpg) no-repeat;
padding-left:25px;
}

add above tags into your CSS file and use the specified class.

   <input type="text" id="text" name="search">
<table id="table_data">
        <tr class="listR"><td>PHP</td></tr>
        <tr class="listR"><td>MySql</td></tr>
        <tr class="listR"><td>AJAX</td></tr>
        <tr class="listR"><td>jQuery</td></tr>
        <tr class="listR"><td>JavaScript</td></tr>
        <tr class="listR"><td>HTML</td></tr>
        <tr class="listR"><td>CSS</td></tr>
        <tr class="listR"><td>CSS3</td></tr>
</table>

$("#textbox").on('keyup',function(){
        var f = $(this).val();
      $("#table_data tr.listR").each(function(){
            if ($(this).text().search(new RegExp(f, "i")) < 0) {
                $(this).fadeOut();
             } else {
                 $(this).show();
            }
        });
    });

Demo You can perform by search() method with use RegExp matching text

**In my case problem solved with Instant Run DISABLE **

There is no way to convert a VBScript (.vbs file) into an executable (.exe file) because VBScript is not a compiled language. The process of converting source code into native executable code is called "compilation", and it's not supported by scripting languages like VBScript.

Certainly you can add your script to a self-extracting archive using something like WinZip, but all that will do is compress it. It's doubtful that the file size will shrink noticeably, and since it's a plain-text file to begin with, it's really not necessary to compress it at all. The only purpose of a self-extracting archive is that decompression software (like WinZip) is not required on the end user's computer to be able to extract or "decompress" the file. If it isn't compressed in the first place, this is a moot point.

Alternatively, as you mentioned, there are ways to wrap VBScript code files in a standalone executable file, but these are just wrappers that automatically execute the script (in its current, uncompiled state) when the user double-clicks on the .exe file. I suppose that can have its benefits, but it doesn't sound like what you're looking for.

In order to truly convert your VBScript into an executable file, you're going to have to rewrite it in another language that can be compiled. Visual Basic 6 (the latest version of VB, before the .NET Framework was introduced) is extremely similar in syntax to VBScript, but does support compiling to native code. If you move your VBScript code to VB 6, you can compile it into a native executable. Running the .exe file will require that the user has the VB 6 Run-time libraries installed, but they come built into most versions of Windows that are found now in the wild.

Alternatively, you could go ahead and make the jump to Visual Basic .NET, which remains somewhat similar in syntax to VB 6 and VBScript (although it won't be anywhere near a cut-and-paste migration). VB.NET programs will also compile to an .exe file, but they require the .NET Framework runtime to be installed on the user's computer. Fortunately, this has also become commonplace, and it can be easily redistributed if your users don't happen to have it. You mentioned going this route in your question (porting your current script in to VB Express 2008, which uses VB.NET), but that you were getting a lot of errors. That's what I mean about it being far from a cut-and-paste migration. There are some huge differences between VB 6/VBScript and VB.NET, despite some superficial syntactical similarities. If you want help migrating over your VBScript, you could post a question here on Stack Overflow. Ultimately, this is probably the best way to do what you want, but I can't promise you that it will be simple.

<?
     $day1 = "2014-01-26 11:30:00";
     $day1 = strtotime($day1);
     $day2 = "2014-01-26 12:30:00";
     $day2 = strtotime($day2);

   $diffHours = round(($day2 - $day1) / 3600);

   echo $diffHours;

?>

In case you don't want to use return statement for each case, try this:

Calculate(int left, int right, Operator op)
{
   int result = 0;
   switch(op)
   {
        case Operator.PLUS:
        {
            result = left + right;;  
        }
        break;
        ....
   }

   return result;
}

There are two issues here. The first is to access fields in the array returned by your JSON parse, the second is to rename collections/fields (like sentences) away from VBA reserved names.

Let's address the second concern first. You were on the right track. First, replace all instances of sentences with jsentences If text within your JSON also contains the word sentences, then figure out a way to make the replacement unique, such as using "sentences":[ as the search string. You can use the VBA Replace method to do this.

Once that's done, so VBA will stop renaming sentences to Sentences, it's just a matter of accessing the array like so:

'first, declare the variables you need:
Dim jsent as Variant

'Get arr all setup, then
For Each jsent in arr.jsentences
  MsgBox(jsent.orig)
Next

$('#input').on("input",function () {alert('changed');});

works for me.

Function:

public float simpleSimilarity(String u, String v) {
    String[] a = u.split(" ");
    String[] b = v.split(" ");

    long correct = 0;
    int minLen = Math.min(a.length, b.length);

    for (int i = 0; i < minLen; i++) {
        String aa = a[i];
        String bb = b[i];
        int minWordLength = Math.min(aa.length(), bb.length());

        for (int j = 0; j < minWordLength; j++) {
            if (aa.charAt(j) == bb.charAt(j)) {
                correct++;
            }
        }
    }

    return (float) (((double) correct) / Math.max(u.length(), v.length()));
}

Test:

String a = "This is the first string.";

String b = "this is not 1st string!";

// for exact string comparison, use .equals

boolean exact = a.equals(b);

// For similarity check, there are libraries for this
// Here I'll try a simple example I wrote

float similarity = simple_similarity(a,b);

In C, except for a few special cases, an array reference always "decays" to a pointer to the first element of the array. Therefore, it isn't possible to pass an array "by value". An array in a function call will be passed to the function as a pointer, which is analogous to passing the array by reference.

EDIT: There are three such special cases where an array does not decay to a pointer to it's first element:

1. sizeof a is not the same as sizeof (&a[0]).
2. &a is not the same as &(&a[0]) (and not quite the same as &a[0]).
3. char b[] = "foo" is not the same as char b[] = &("foo").

Free, and no external DLL files. Everything is in one CS file. One download is just the CS file, another download is a very easy to understand example. Just tried it today and I can't believe how simple the setup was. It worked on first try, no errors, no nothing.

Well, depending on your needs you can choose any of the following. Out put is written against each method

You can choose the one you need

This will round

decimal d = 2.5789m;
Console.WriteLine(d.ToString("#.##")); // 2.58

This will ensure that 2 decimal places are written.

d = 2.5m;
Console.WriteLine(d.ToString("F")); //2.50

if you want to write commas you can use this

d=23545789.5432m;
Console.WriteLine(d.ToString("n2")); //23,545,789.54

if you want to return the rounded of decimal value you can do this

d = 2.578m;
d = decimal.Round(d, 2, MidpointRounding.AwayFromZero); //2.58

Sam's solution is already great, despite it doesn't take different bundles into account (NSBundle:forClass comes to the rescue) and requires manual loading, a.k.a typing code.

If you want full support for your Xib Outlets, different Bundles (use in frameworks!) and get a nice preview in Storyboard try this:

// NibLoadingView.swift
import UIKit

/* Usage: 
- Subclass your UIView from NibLoadView to automatically load an Xib with the same name as your class
- Set the class name to File's Owner in the Xib file
*/

@IBDesignable
class NibLoadingView: UIView {

    @IBOutlet weak var view: UIView!

    override init(frame: CGRect) {
        super.init(frame: frame)
        nibSetup()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        nibSetup()
    }

    private func nibSetup() {
        backgroundColor = .clearColor()

        view = loadViewFromNib()
        view.frame = bounds
        view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
        view.translatesAutoresizingMaskIntoConstraints = true

        addSubview(view)
    }

    private func loadViewFromNib() -> UIView {
        let bundle = NSBundle(forClass: self.dynamicType)
        let nib = UINib(nibName: String(self.dynamicType), bundle: bundle)
        let nibView = nib.instantiateWithOwner(self, options: nil).first as! UIView

        return nibView
    }

}

Use your xib as usual, i.e. connect Outlets to File Owner and set File Owner class to your own class.

Usage: Just subclass your own View class from NibLoadingView & Set the class name to File's Owner in the Xib file

No additional code required anymore.

You can use any XML API of Java as Document and Node..as XML is a tree structure with Strings

Using Firebase's Query API, you might be tempted to try this:

// !!! THIS WILL NOT WORK !!!
ref
  .orderBy('genre')
  .startAt('comedy').endAt('comedy')
  .orderBy('lead')                  // !!! THIS LINE WILL RAISE AN ERROR !!!
  .startAt('Jack Nicholson').endAt('Jack Nicholson')
  .on('value', function(snapshot) { 
      console.log(snapshot.val()); 
  });

But as @RobDiMarco from Firebase says in the comments:

multiple orderBy() calls will throw an error

So my code above will not work.

I know of three approaches that will work.

1. filter most on the server, do the rest on the client

What you can do is execute one orderBy().startAt()./endAt() on the server, pull down the remaining data and filter that in JavaScript code on your client.

ref
  .orderBy('genre')
  .equalTo('comedy')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      if (movie.lead == 'Jack Nicholson') {
          console.log(movie);
      }
  });

2. add a property that combines the values that you want to filter on

If that isn't good enough, you should consider modifying/expanding your data to allow your use-case. For example: you could stuff genre+lead into a single property that you just use for this filter.

"movie1": {
    "genre": "comedy",
    "name": "As good as it gets",
    "lead": "Jack Nicholson",
    "genre_lead": "comedy_Jack Nicholson"
}, //...

You're essentially building your own multi-column index that way and can query it with:

ref
  .orderBy('genre_lead')
  .equalTo('comedy_Jack Nicholson')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      console.log(movie);
  });

David East has written a library called QueryBase that helps with generating such properties.

You could even do relative/range queries, let's say that you want to allow querying movies by category and year. You'd use this data structure:

"movie1": {
    "genre": "comedy",
    "name": "As good as it gets",
    "lead": "Jack Nicholson",
    "genre_year": "comedy_1997"
}, //...

And then query for comedies of the 90s with:

ref
  .orderBy('genre_year')
  .startAt('comedy_1990')
  .endAt('comedy_2000')
  .on('child_added', function(snapshot) { 
      var movie = snapshot.val();
      console.log(movie);
  });

If you need to filter on more than just the year, make sure to add the other date parts in descending order, e.g. "comedy_1997-12-25". This way the lexicographical ordering that Firebase does on string values will be the same as the chronological ordering.

This combining of values in a property can work with more than two values, but you can only do a range filter on the last value in the composite property.

A very special variant of this is implemented by the GeoFire library for Firebase. This library combines the latitude and longitude of a location into a so-called Geohash, which can then be used to do realtime range queries on Firebase.

3. create a custom index programmatically

Yet another alternative is to do what we've all done before this new Query API was added: create an index in a different node:

  "movies"
      // the same structure you have today
  "by_genre"
      "comedy"
          "by_lead"
              "Jack Nicholson"
                  "movie1"
              "Jim Carrey"
                  "movie3"
      "Horror"
          "by_lead"
              "Jack Nicholson"
                  "movie2"
      

There are probably more approaches. For example, this answer highlights an alternative tree-shaped custom index: https://stackoverflow.com/a/34105063

If none of these options work for you, but you still want to store your data in Firebase, you can also consider using its Cloud Firestore database.

Cloud Firestore can handle multiple equality filters in a single query, but only one range filter. Under the hood it essentially uses the same query model, but it's like it auto-generates the composite properties for you. See Firestore's documentation on compound queries.

I had the same issue, but with a different cause that may help others.

Use a commandprompt in admin mode for this: - TYPE: netsh http show iplisten If there are any IP entries: - TYPE: netsh http delete iplisten Repeat until the list is empty. Check if IIS Express starts now.

Hope this helps, Niels

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

This happened to me after I ran a script with cProfile a la python3 -m cProfile script.py even though xlrd was already installed and had never thrown this error before. it persisted even under python3 script.py. (Granted, I agree this wasn't what happened to OP, given the obvious import error)

However, for cases like mine, the following fixed the issue, despite being told "requirement already met" in every case.

pip install --upgrade pandas
pip install --upgrade xlrd

Pretty confounding stuff; not sure if cProfile was the cause or just a coincidence

The following should work, assuming your pip install operated on python2.

python3 -m pip install xlrd

The easiest way to do this, is to use the disabled attribute, as you had done in your original question:

<button class="btn btn-disabled" disabled>Content of Button</button>

As of now, Twitter Bootstrap doesn't have a method to disable a button's functionality without using the disabled attribute.

Nonetheless, this would be an excellent feature for them to implement into their javascript library.

Alternatively, you could invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

I liked this example.

You don't say which version of Excel you are using. This is written for 2007/2010 (a different apprach is required for Excel 2003 )

You also don't say how you are calling addDataToTable and what you are passing into arrData.
I'm guessing you are passing a 0 based array. If this is the case (and the Table starts in Column A) then iCount will count from 0 and .Cells(lLastRow + 1, iCount) will try to reference column 0 which is invalid.

You are also not taking advantage of the ListObject. Your code assumes the ListObject1 is located starting at row 1. If this is not the case your code will place the data in the wrong row.

Here's an alternative that utilised the ListObject

Sub MyAdd(ByVal strTableName As String, ByRef arrData As Variant)
    Dim Tbl As ListObject
    Dim NewRow As ListRow

    ' Based on OP 
    ' Set Tbl = Worksheets(4).ListObjects(strTableName)
    ' Or better, get list on any sheet in workbook
    Set Tbl = Range(strTableName).ListObject
    Set NewRow = Tbl.ListRows.Add(AlwaysInsert:=True)

    ' Handle Arrays and Ranges
    If TypeName(arrData) = "Range" Then
        NewRow.Range = arrData.Value
    Else
        NewRow.Range = arrData
    End If
End Sub

Can be called in a variety of ways:

Sub zx()
    ' Pass a variant array copied from a range
    MyAdd "MyTable", [G1:J1].Value
    ' Pass a range
    MyAdd "MyTable", [G1:J1]
    ' Pass an array
    MyAdd "MyTable", Array(1, 2, 3, 4)
End Sub

The primary key in Cassandra usually consists of two parts - Partition key and Clustering columns.

primary_key((partition_key), clustering_col )

Partition key - The first part of the primary key. The main aim of a partition key is to identify the node which stores the particular row.

CREATE TABLE phone_book ( phone_num int, name text, age int, city text, PRIMARY KEY ((phone_num, name), age);

Here, (phone_num, name) is the partition key. While inserting the data, the hash value of the partition key is generated and this value decides which node the row should go into.

Consider a 4 node cluster, each node has a range of hash values it can store. (Write) INSERT INTO phone_book VALUES (7826573732, ‘Joey’, 25, ‘New York’);

Now, the hash value of the partition key is calculated by Cassandra partitioner. say, hash value(7826573732, ‘Joey’) ? 12 , now, this row will be inserted in Node C.

(Read) SELECT * FROM phone_book WHERE phone_num=7826573732 and name=’Joey’;

Now, again the hash value of the partition key (7826573732,’Joey’) is calculated, which is 12 in our case which resides in Node C, from which the read is done.

2. Clustering columns - Second part of the primary key. The main purpose of having clustering columns is to store the data in a sorted order. By default, the order is ascending.

There can be more than one partition key and clustering columns in a primary key depending on the query you are solving.

primary_key((pk1, pk2), col 1,col2)

... Or instead of treating the commas as garbage to be filtered out, we could treat the overall string as a localized formatting of the float, and use the localization services:

from locale import atof, setlocale, LC_NUMERIC
setlocale(LC_NUMERIC, '') # set to your default locale; for me this is
# 'English_Canada.1252'. Or you could explicitly specify a locale in which floats
# are formatted the way that you describe, if that's not how your locale works :)
atof('123,456') # 123456.0
# To demonstrate, let's explicitly try a locale in which the comma is a
# decimal point:
setlocale(LC_NUMERIC, 'French_Canada.1252')
atof('123,456') # 123.456

There are several possible catches. I think that the most common error is in this part of the connection string:

res://xxx/yyy.csdl|res://xxx/yyy.ssdl|res://xxx/yyy.msl;

This is no magic. Once you understand what is stands for you'll get the connection string right.

First the xxx part. That's nothing else than an assembly name where you defined you EF context clas. Usually it would be something like MyProject.Data. Default value is * which stands for all loaded assemblies. It's always better to specify a particular assembly name.

Now the yyy part. That's a resource name in the xxx assembly. It will usually be something like a relative path to your .edmx file with dots instead of slashes. E.g. Models/Catalog - Models.Catalog The easiest way to get the correct string for your application is to build the xxx assembly. Then open the assembly dll file in a text editor (I prefer the Total Commander's default viewer) and search for ".csdl". Usually there won't be more than 1 occurence of that string.

Your final EF connection string may look like this:

res://MyProject.Data/Models.Catalog.DataContext.csdl|res://MyProject.Data/Models.Catalog.DataContext.ssdl|res://MyProject.Data/Models.Catalog.DataContext.msl;

I got this error because i was calling "notifyItemInserted" twice by mistake.

I used below method, which doesn't require any change in config, tested on mysql-5.5.51-winx64 and 5.5.50-MariaDB:

put 'load data...' in .sql file (ex: LoadTableName.sql)

LOAD DATA INFILE 'D:\\Work\\TableRecords.csv' INTO TABLE tbl1 FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (col1,col2);

then:

mysql -uroot -pStr0ngP@ss -Ddatabasename -e "source D:\Work\LoadTableName.sql"

list multiplication works.

>>> [0] * 10
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

You can try ng-file-upload angularjs plugin (instead of ng-upload).

It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

html

<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script> 
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script> 

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        data: {myObj: $scope.myModelObj},
        file: file,
      }).progress(function(evt) {
        console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
      }).then(function(response) {
        var data = response.data;
        // file is uploaded successfully
        console.log(data);
      });
    }
  };
}];

Its simply creating a wrapper to call multiple methods . You have an A class with method x() and y() and B class with method k() and z(). You want to call x, y, z at once , to do that using Facade pattern you just create a Facade class and create a method lets say xyz(). Instead of calling each method (x,y and z) individually you just call the wrapper method (xyz()) of the facade class which calls those methods .

Similar pattern is repository but it s mainly for the data access layer.

Yes; all primitive numeric types default to 0.

However, calculations involving floating-point types (double and float) can be imprecise, so it's usually better to check whether it's close to 0:

if (Math.abs(foo.x) < 2 * Double.MIN_VALUE)

You need to pick a margin of error, which is not simple.

Although all other answers are technically correct, I would recommend you adding the custom path to the beginning of your PATH, not at the end. That way it would be the first place to look for instead of the last:

Add to bottom of ~/.bash_profile:

export PATH="/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/":$PATH

That way if you have more than one java or javac it will use the one you provided first.

I wrote about it on my blog a long time ago, WPF's support for common file dialogs is really bad (or at least is was in 3.5 I didn't check in version 4) - but it's easy to work around it.

You need to add the correct manifest to your application - that will give you a modern style message boxes and folder browser (WinForms FolderBrowserDialog) but not WPF file open/save dialogs, this is described in those 3 posts (if you don't care about the explanation and only want the solution go directly to the 3rd):

• Why am I Getting Old Style File Dialogs and Message Boxes with WPF
• Will Setting a Manifest Solve My WPF Message Box Style Problems?
• The Application Manifest Needed for XP and Vista Style File Dialogs and Message Boxes with WPF

Fortunately, the open/save dialogs are very thin wrappers around the Win32 API that is easy to call with the right flags to get the Vista/7 style (after setting the manifest)

• Vista style open and save dialogs with WPF (without using the Vista bridge sample)

and add textbox StaticResource style

  <TextBox

<?php
$myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
echo fread($myfile,filesize("webdictionary.txt"));
fclose($myfile);
?>

Try this to open a file in php

Refer this: (http://www.w3schools.com/php/showphp.asp?filename=demo_file_fopen)

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

This works fine for me:

{{ app('request')->input('a') }}

Ex: to get pagination param on blade view:

{{ app('request')->input('page') }}

ALLOW-FROM is not supported in Chrome or Safari. See MDN article: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options

You are already doing the work to make a custom header and send it with the correct data, can you not just exclude the header when you detect it is from a valid partner and add DENY to every other request? I don't see the benefit of AllowFrom when you are already dynamically building the logic up?

You could also try to include md5-hash-sums or similar do determine whether there are any differences at all. Then, only compare files which have different hashes...

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

Array.prototype.removeItem = function(a) {
    for (i = 0; i < this.length; i++) {
        if (this[i] == a) {
            for (i2 = i; i2 < this.length - 1; i2++) {
                this[i2] = this[i2 + 1];
            }
            this.length = this.length - 1
            return;
        }
    }
}

var recentMovies = ['Iron Man', 'Batman', 'Superman', 'Spiderman'];
recentMovies.removeItem('Superman');

Kotlin Solution:

1) Paste this extension function somewhere.

fun LocalDate.toDate(): Date = Date.from(this.atStartOfDay(ZoneId.systemDefault()).toInstant())

2) Use it, and never google this again.

val myDate = myLocalDate.toDate()

Try ["points.bean.pointsBase"]

There is no such thing as a byte or short literal. You need to cast to short using (short)100

you can also use the following:

s.concat("world")

You can use the sp_MSforeachtable stored procedure like so:

USE MyDatabase
EXEC sp_MSforeachtable 'TRUNCATE TABLE ?'

Be warned that this will delete (by truncation) ALL data from all user tables. And in case you can't TRUNCATE due to foreign keys etc. you can run the same as a delete:

USE MyDatabase
EXEC sp_MSforeachtable 'DELETE FROM ?'

Woohoo my first post even though this is a year old. To avoid the background-coloring issues with wrappers, you could use inline-block with hr (nobody said that explicitly). Text-align should center correctly since they are inline elements.

<div style="text-align:center">
    <hr style="display:inline-block; position:relative; top:4px; width:45%" />
       &nbsp;New Section&nbsp;
    <hr style="display:inline-block; position:relative; top:4px; width:45%" />
</div>

If JSON is dynamic as below

{
 "Items": [{
        "Name": "Apple",
        "Price": 12.3
    },
    {
        "Name": "Grape",
        "Price": 3.21
    }
   ],
   "Date": "21/11/2010"
}

Then, Once you install NewtonSoft.Json from NuGet and include it in your project, you can serialize it as

string jsonString = "{\"Items\": [{\"Name\": \"Apple\",\"Price\": 12.3},{\"Name\": \"Grape\",\"Price\": 3.21}],\"Date\": \"21/11/2010\"}";

        dynamic DynamicData = JsonConvert.DeserializeObject(jsonString);

        Console.WriteLine(   DynamicData.Date); // "21/11/2010"
        Console.WriteLine(DynamicData.Items.Count); // 2
        Console.WriteLine(DynamicData.Items[0].Name); // "Apple"

Source: How to read JSON data in C# (Example using Console app & ASP.NET MVC)?

When posting form data with an HTML form, be sure the input tags have name attributes, otherwise they won't be present in request.form.

@app.route('/', methods=['GET', 'POST'])
def index():
    print(request.form)
    return """
<form method="post">
    <input type="text">
    <input type="text" id="txt2">
    <input type="text" name="txt3" id="txt3">  
    <input type="submit">
</form>
"""

ImmutableMultiDict([('txt3', 'text 3')])

Only the txt3 input had a name, so it's the only key present in request.form.

Here's how I ended up doing this:

        <div id="divform">
            <form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
                <div>Certificate 1: <input type="file" name="cert1"/></div>
                <div>Certificate 2: <input type="file" name="cert2"/></div>

                <div><input type="button" value="Upload" onclick="closeSelf();"/></div>
            </form>
        </div>
        <div  id="closelink" style="display:none">
            <a href="javascript:window.close()">Click Here to Close this Page</a>
        </div>

function closeSelf(){
    document.forms['certform'].submit();
    hide(document.getElementById('divform'));
    unHide(document.getElementById('closelink'));

}

Where hide() and unhide() set the style.display to 'none' and 'block' respectively.

Not exactly what I had in mind, but this will have to do for the time being. Works on IE, Safari, FF and Chrome.

Here is the syntax to create a trigger:

CREATE TRIGGER trigger_name
ON { table | view }
[ WITH ENCRYPTION ]
{
    { { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] }
        [ WITH APPEND ]
        [ NOT FOR REPLICATION ]
        AS
        [ { IF UPDATE ( column )
            [ { AND | OR } UPDATE ( column ) ]
                [ ...n ]
        | IF ( COLUMNS_UPDATED ( ) { bitwise_operator } updated_bitmask )
                { comparison_operator } column_bitmask [ ...n ]
        } ]
        sql_statement [ ...n ]
    }
} 

If you want to use On Update you only can do it with the IF UPDATE ( column ) section. That's not possible to do what you are asking.

If you want the exact number of full months, always positive (2000-01-15, 2000-02-14 returns 0), considering a full month is when you reach the same day the next month (something like the age calculation)

public static int GetMonthsBetween(DateTime from, DateTime to)
{
    if (from > to) return GetMonthsBetween(to, from);

    var monthDiff = Math.Abs((to.Year * 12 + (to.Month - 1)) - (from.Year * 12 + (from.Month - 1)));

    if (from.AddMonths(monthDiff) > to || to.Day < from.Day)
    {
        return monthDiff - 1;
    }
    else
    {
        return monthDiff;
    }
}

Edit reason: the old code was not correct in some cases like :

new { From = new DateTime(1900, 8, 31), To = new DateTime(1901, 8, 30), Result = 11 },

Test cases I used to test the function:

var tests = new[]
{
    new { From = new DateTime(1900, 1, 1), To = new DateTime(1900, 1, 1), Result = 0 },
    new { From = new DateTime(1900, 1, 1), To = new DateTime(1900, 1, 2), Result = 0 },
    new { From = new DateTime(1900, 1, 2), To = new DateTime(1900, 1, 1), Result = 0 },
    new { From = new DateTime(1900, 1, 1), To = new DateTime(1900, 2, 1), Result = 1 },
    new { From = new DateTime(1900, 2, 1), To = new DateTime(1900, 1, 1), Result = 1 },
    new { From = new DateTime(1900, 1, 31), To = new DateTime(1900, 2, 1), Result = 0 },
    new { From = new DateTime(1900, 8, 31), To = new DateTime(1900, 9, 30), Result = 0 },
    new { From = new DateTime(1900, 8, 31), To = new DateTime(1900, 10, 1), Result = 1 },
    new { From = new DateTime(1900, 1, 1), To = new DateTime(1901, 1, 1), Result = 12 },
    new { From = new DateTime(1900, 1, 1), To = new DateTime(1911, 1, 1), Result = 132 },
    new { From = new DateTime(1900, 8, 31), To = new DateTime(1901, 8, 30), Result = 11 },
};

I think it's better to point out that using Make (recursive or not) is something that usually you may want to avoid, because compared to today tools, it's difficult to learn, maintain and scale.

It's a wonderful tool but it's direct use should be considered obsolete in 2010+.

Unless, of course, you're working in a special environment i.e. with a legacy project etc.

Use an IDE, CMake or, if you're hard cored, the Autotools.

(edited due to downvotes, ty Honza for pointing out)

By default, the hr element in Twitter Bootstrap CSS file has a top and bottom margin of 18px. That's what creates a gap. If you want the gap to be smaller you'll need to adjust margin property of the hr element.

In your example, do something like this:

.container hr {
margin: 2px 0;
}

if(Number.isInteger(Number(data))){

Update 2016:

Google Chrome released the storage API: http://developer.chrome.com/extensions/storage.html

It is pretty easy to use like the other Chrome APIs and you can use it from any page context within Chrome.

    // Save it using the Chrome extension storage API.
    chrome.storage.sync.set({'foo': 'hello', 'bar': 'hi'}, function() {
      console.log('Settings saved');
    });

    // Read it using the storage API
    chrome.storage.sync.get(['foo', 'bar'], function(items) {
      message('Settings retrieved', items);
    });

To use it, make sure you define it in the manifest:

    "permissions": [
      "storage"
    ],

There are methods to "remove", "clear", "getBytesInUse", and an event listener to listen for changed storage "onChanged"

Using native localStorage (old reply from 2011)

Content scripts run in the context of webpages, not extension pages. Therefore, if you're accessing localStorage from your contentscript, it will be the storage from that webpage, not the extension page storage.

Now, to let your content script to read your extension storage (where you set them from your options page), you need to use extension message passing.

The first thing you do is tell your content script to send a request to your extension to fetch some data, and that data can be your extension localStorage:

contentscript.js

chrome.runtime.sendMessage({method: "getStatus"}, function(response) {
  console.log(response.status);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getStatus")
      sendResponse({status: localStorage['status']});
    else
      sendResponse({}); // snub them.
});

You can do an API around that to get generic localStorage data to your content script, or perhaps, get the whole localStorage array.

I hope that helped solve your problem.

To be fancy and generic ...

contentscript.js

chrome.runtime.sendMessage({method: "getLocalStorage", key: "status"}, function(response) {
  console.log(response.data);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getLocalStorage")
      sendResponse({data: localStorage[request.key]});
    else
      sendResponse({}); // snub them.
});

If the XML module is not installed, install it.

Current version 5.6 on ubuntu 14.04:

public T[] toArray(T[] a) - In this method we create a array with size of arraylist and pass it as argument and it will return array of element of arraylist

    String[] arr = new String[list.size()]; 

    arr = list.toArray(arr);

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

Adding onKeyPress will work onChange in Text Field.

<TextField
  onKeyPress={(ev) => {
    console.log(`Pressed keyCode ${ev.key}`);
    if (ev.key === 'Enter') {
      // Do code here
      ev.preventDefault();
    }
  }}
/>

Sounds like you probably want a simple method like this:

public String getValueOrDefault(String value, String defaultValue) {
    return isNotNullOrEmpty(value) ? value : defaultValue;
}

Then:

String result = getValueOrDefault(System.getProperty("XYZ"), "default");

At this point, you don't need temp... you've effectively used the method parameter as a way of initializing the temporary variable.

If you really want temp and you don't want an extra method, you can do it in one statement, but I really wouldn't:

public class Test {
    public static void main(String[] args) {
        String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
        System.out.println("result: " + result);
        System.out.println("temp: " + temp);
    }

    private static boolean isNotNullOrEmpty(String str) {
        return str != null && !str.isEmpty();
    }
}

Why choose between a traditional database and a NoSQL data store? Use both! The problem with NoSQL solutions (beyond the initial learning curve) is the lack of transactions -- you do all updates to MySQL and have MySQL populate a NoSQL data store for reads -- you then benefit from each technology's strengths. This does add more complexity, but you already have the MySQL side -- just add MongoDB, Cassandra, etc to the mix.

NoSQL datastores generally scale way better than a traditional DB for the same otherwise specs -- there is a reason why Facebook, Twitter, Google, and most start-ups are using NoSQL solutions. It's not just geeks getting high on new tech.

A simpler Java 8 alternative:

JSONArray data = new JSONArray(); //create data from this -> [{"thumb_url":"tb-1370913834.jpg","event_id":...}]

List<JSONObject> list = data.stream().map(o -> (JSONObject) o).collect(Collectors.toList());

The other methods described assume a binary mask. If you want to use a real-valued single-channel grayscale image as a mask (e.g. from an alpha channel), you can expand it to three channels and then use it for interpolation:

assert len(mask.shape) == 2 and issubclass(mask.dtype.type, np.floating)
assert len(foreground_rgb.shape) == 3
assert len(background_rgb.shape) == 3

alpha3 = np.stack([mask]*3, axis=2)
blended = alpha3 * foreground_rgb + (1. - alpha3) * background_rgb

Note that mask needs to be in range 0..1 for the operation to succeed. It is also assumed that 1.0 encodes keeping the foreground only, while 0.0 means keeping only the background.

If the mask may have the shape (h, w, 1), this helps:

alpha3 = np.squeeze(np.stack([np.atleast_3d(mask)]*3, axis=2))

Here np.atleast_3d(mask) makes the mask (h, w, 1) if it is (h, w) and np.squeeze(...) reshapes the result from (h, w, 3, 1) to (h, w, 3).

Try this (apply to a class you image is in (not img itself), e.g.

.myimage {
  background: transparent url("yourimage.png") no-repeat top center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: 100%;
  height: 500px;
}

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset {

    CGPoint targetPoint = *targetContentOffset;
    CGPoint currentPoint = scrollView.contentOffset;

    if (targetPoint.y > currentPoint.y) {
        NSLog(@"up");
    }
    else {
        NSLog(@"down");
    }
}

Just use break, like that:

int cont = 0;
foreach (ListViewItem lvi in listView.Items) {
   if(cont==50) { //if listViewItem reach 50 break out.
      break; 
   }
   cont++;   //increment cont.
}

To use getSingleResult on a TypedQuery you can use

query.setFirstResult(0);
query.setMaxResults(1);
result = query.getSingleResult();

In MySQL

select convert( if( listPrice REGEXP '^[0-9]+$', listPrice, '0' ), DECIMAL(15, 3) ) from MyProduct WHERE 1

//Add a list of BBDD
var item = myEntities.getList().ToList();
//Insert a new object of type in a position of the list       
item.Insert(0,(new Model.getList_Result { id = 0, name = "Coca Cola" }));

//List assigned to DataGridView
dgList.DataSource = item; 

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

For react-native users who don't use Xcode often, you can just use find. Open a terminal and search by with the database name.

$ find ~/Library/Developer -name 'myname.db'

If you don't know the exact name you can use wildcards:

$ find ~/Library/Developer -name 'myname.*'

For anyone stumbling here like I did, here is a jQuery 1.10.2 version I wrote which is working very well for me albeit resource intensive:

/***************************************************
* Only allow numbers and one decimal in text boxes
***************************************************/
$('body').on('keydown keyup keypress change blur focus paste', 'input[type="text"]', function(){
    var target = $(this);

    var prev_val = target.val();

    setTimeout(function(){
        var chars = target.val().split("");

        var decimal_exist = false;
        var remove_char = false;

        $.each(chars, function(key, value){
            switch(value){
                case '0':
                case '1':
                case '2':
                case '3':
                case '4':
                case '5':
                case '6':
                case '7':
                case '8':
                case '9':
                case '.':
                    if(value === '.'){
                        if(decimal_exist === false){
                            decimal_exist = true;
                        }
                        else{
                            remove_char = true;
                            chars[''+key+''] = '';
                        }
                    }
                    break;
                default:
                    remove_char = true;
                    chars[''+key+''] = '';
                    break;
            }
        });

        if(prev_val != target.val() && remove_char === true){
            target.val(chars.join(''))
        }
    }, 0);
});

You can pass multiple arguments like this.

List<object> arguments = new List<object>();
arguments.Add("first");      //argument 1
arguments.Add(new Object()); //argument 2
// ...
arguments.Add(10);           //argument n

backgroundWorker.RunWorkerAsync(arguments);

private void worker_DoWork(object sender, DoWorkEventArgs e) 
{
  List<object> genericlist = e.Argument as List<object>;
  //extract your multiple arguments from 
  //this list and cast them and use them. 
}

Remove the display:none, and use ng-show instead:

<ul class="procedures">
    <li ng-repeat="procedure in procedures | filter:query | orderBy:orderProp">
        <h4><a href="#" ng-click="showDetails = ! showDetails">{{procedure.definition}}</a></h4>
         <div class="procedure-details" ng-show="showDetails">
            <p>Number of patient discharges: {{procedure.discharges}}</p>
            <p>Average amount covered by Medicare: {{procedure.covered}}</p>
            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

Here's the fiddle: http://jsfiddle.net/asmKj/

You can also use ng-class to toggle a class:

<div class="procedure-details" ng-class="{ 'hidden': ! showDetails }">

I like this more, since it allows you to do some nice transitions: http://jsfiddle.net/asmKj/1/

This work better for me. Try :

 self.navigationController.navigationBar.topItem.backBarButtonItem = [[UIBarButtonItem alloc] 
initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil];

Solving this problem is much more within reach nowadays. The HTML5 History API allows us to manipulate the location bar to display any URL within the current domain.

function removeHash () { 
    history.pushState("", document.title, window.location.pathname
                                                       + window.location.search);
}

Working demo: http://jsfiddle.net/AndyE/ycmPt/show/

This works in Chrome 9, Firefox 4, Safari 5, Opera 11.50 and in IE 10. For unsupported browsers, you could always write a gracefully degrading script that makes use of it where available:

function removeHash () { 
    var scrollV, scrollH, loc = window.location;
    if ("pushState" in history)
        history.pushState("", document.title, loc.pathname + loc.search);
    else {
        // Prevent scrolling by storing the page's current scroll offset
        scrollV = document.body.scrollTop;
        scrollH = document.body.scrollLeft;

        loc.hash = "";

        // Restore the scroll offset, should be flicker free
        document.body.scrollTop = scrollV;
        document.body.scrollLeft = scrollH;
    }
}

So you can get rid of the hash symbol, just not in all browsers — yet.

_{Note: if you want to replace the current page in the browser history, use replaceState() instead of pushState().}

Just to let everyone out there know that is using Linq to Entities the methods above will not work...

If you try to do something like

var max = new[]{0}
      .Concat((From y In context.MyTable _
               Where y.MyField = value _
               Select y.MyCounter))
      .Max();

It will throw an exception:

System.NotSupportedException: The LINQ expression node type 'NewArrayInit' is not supported in LINQ to Entities..

I would suggest just doing

(From y In context.MyTable _
                   Where y.MyField = value _
                   Select y.MyCounter))
          .OrderByDescending(x=>x).FirstOrDefault());

And the FirstOrDefault will return 0 if your list is empty.

I'm not sure if this answers your question, but using the IS NULL construct, you can test whether any given scalar expression is NULL:

SELECT * FROM customers WHERE first_name IS NULL

On MS SQL Server, the ISNULL() function returns the first argument if it's not NULL, otherwise it returns the second. You can effectively use this to make sure a query always yields a value instead of NULL, e.g.:

SELECT ISNULL(column1, 'No value found') FROM mytable WHERE column2 = 23

Other DBMSes have similar functionality available.

If you want to know whether a column can be null (i.e., is defined to be nullable), without querying for actual data, you should look into information_schema.

In my experience, the things I need to make environment-specific are things like connection strings, appsettings and often smpt settings. The config system allows to specify these things in separate files. So you can use this in your app.config/web.config:

 <appSettings configSource="appsettings.config" />
 <connectionStrings configSource="connection.config" />
 <system.net>
    <mailSettings>
       <smtp configSource="smtp.config"/>
    </mailSettings>
 </system.net>

What I typically do is to put these config-specific sections in separate files, in a subfolder called ConfigFiles (either in the solution root or at the project level, depends). I define a file per configuration, e.g. smtp.config.Debug and smtp.config.Release.

Then you can define a pre-build event like so:

copy $(ProjectDir)ConfigFiles\smtp.config.$(ConfigurationName) $(TargetDir)smtp.config

In team development, you can tweak this further by including the %COMPUTERNAME% and/or %USERNAME% in the convention.

Of course, this implies that the target files (x.config) should NOT be put in source control (since they are generated). You should still add them to the project file and set their output type property to 'copy always' or 'copy if newer' though.

Simple, extensible, and it works for all types of Visual Studio projects (console, winforms, wpf, web).

My case: configuring the service on new server. ASP.NET 4.0 was not installed/registered properly; svc extension was not recognized.

Objects in JavaScript can be thought of as associative arrays, mapping keys (properties) to values.

To remove a property from an object in JavaScript you use the delete operator:

const o = { lastName: 'foo' }
o.hasOwnProperty('lastName') // true
delete o['lastName']
o.hasOwnProperty('lastName') // false

Note that when delete is applied to an index property of an Array, you will create a sparsely populated array (ie. an array with a missing index).

When working with instances of Array, if you do not want to create a sparsely populated array - and you usually don't - then you should use Array#splice or Array#pop.

Note that the delete operator in JavaScript does not directly free memory. Its purpose is to remove properties from objects. Of course, if a property being deleted holds the only remaining reference to an object o, then o will subsequently be garbage collected in the normal way.

Using the delete operator can affect JavaScript engines' ability to optimise code.

I fixed this issue by reinstalling it in Program Files, it originally tried to install it in c:/Users/.../AppData/Android/....

Mine was caused by a user permission issue that running as admin didn't seem to fix (perhaps because they call batch files?).

Try:

title = re.search('<title>(.*)</title>', html, re.IGNORECASE).group(1)

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

THanks!

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

The solution which ultimately worked best for my organization is detailed below, it just adds a check on render for the sysadmin route and redirects the user to a different main path of the application if they are not allowed to be in the page.

SysAdminRoute.tsx

import React from 'react';
import { Route, Redirect, RouteProps } from 'react-router-dom';
import AuthService from '../services/AuthService';
import { appSectionPageUrls } from './appSectionPageUrls';
interface IProps extends RouteProps {}
export const SysAdminRoute = (props: IProps) => {
    var authService = new AuthService();
    if (!authService.getIsSysAdmin()) { //example
        authService.logout();
        return (<Redirect to={{
            pathname: appSectionPageUrls.site //front-facing
        }} />);
    }
    return (<Route {...props} />);
}

There are 3 main routes for our implementation, the public facing /site, the logged in client /app, and sys admin tools at /sysadmin. You get redirected based on your 'authiness' and this is the page at /sysadmin.

SysAdminNav.tsx

<Switch>
    <SysAdminRoute exact path={sysadminUrls.someSysAdminUrl} render={() => <SomeSysAdminUrl/> } />
    //etc
</Switch>
