Just try encodeURI() and encodeURIComponent() yourself...

console.log(encodeURIComponent('@#$%^&*'));

Input: @#$%^&*. Output: %40%23%24%25%5E%26*. So, wait, what happened to *? Why wasn't this converted? TLDR: You actually want fixedEncodeURIComponent() and fixedEncodeURI(). Long-story...

You should not be using encodeURIComponent() or encodeURI(). You should use fixedEncodeURIComponent() and fixedEncodeURI(), according to the MDN Documentation.

Regarding encodeURI()...

If one wishes to follow the more recent RFC3986 for URLs, which makes square brackets reserved (for IPv6) and thus not encoded when forming something which could be part of a URL (such as a host), the following code snippet may help:

function fixedEncodeURI(str) { return encodeURI(str).replace(/%5B/g, '[').replace(/%5D/g, ']'); }

Regarding encodeURIComponent()...

To be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

function fixedEncodeURIComponent(str) { return encodeURIComponent(str).replace(/[!'()*]/g, function(c) { return '%' + c.charCodeAt(0).toString(16); }); }

So, what is the difference? fixedEncodeURI() and fixedEncodeURIComponent() convert the same set of values, but fixedEncodeURIComponent() also converts this set: +@?=:*#;,$&. This set is used in GET parameters (&, +, etc.), anchor tags (#), wildcard tags (*), email/username parts (@), etc..

For example -- If you use encodeURI(), [email protected]/?email=me@home will not properly send the second @ to the server, except for your browser handling the compatibility (as Chrome naturally does often).

To be clear when you us the drag indicator it will only copy the cell values down the column whilst there is a value in the adjacent cell in a given row. As soon as the drag operation sees an adjacent cell that is blank it will stop copying the formula down.

.e.g

1,a,b
2,a
3,
4,a

If the above is a spreadsheet then using the double click drag indicator on the 'b' cell will fill row 2 but not row three or four.

Suppose we have a df_data data frame as below

> df_data
   ID MONTH-YEAR VALUE
1 110   JAN.2012  1000
2 111   JAN.2012  2000
3 121   FEB.2012  3000
4 131   FEB.2012  4000
5 141   MAR.2012  5000

To count number of rows in df_data grouped by MONTH-YEAR column, you can use:

> summary(df_data$`MONTH-YEAR`)

FEB.2012 JAN.2012 MAR.2012 
   2        2        1 

summary function will create a table from the factor argument, then create a vector for the result (line 7 & 8)

Declare in your Model with

  [DataType(DataType.MultilineText)]
  public string urString { get; set; }

Then in .cshtml can make use of editor as below. you can make use of @cols and @rows for TextArea size

     @Html.EditorFor(model => model.urString, new { htmlAttributes = new { @class = "",@cols = 35, @rows = 3 } })

Thanks !

This is what helped me to understand the difference, thanks to a blog post by Pascal Precht.

A service is a method on a module that takes a name and a function that defines the service. You can inject and use that particular service in other components, like controllers, directives and filters. A factory is a method on a module and it also takes a name and a function, that defines the factory. We can also inject and use the it same way we did with the service.

Objects created with new use the value of the prototype property of their constructor function as their prototype, so I found the Angular code that calls Object.create(), that I believe is the service constructor function when it gets instantiated. However, a factory function is really just a function that gets called, which is why we have to return an object literal for the factory.

Here is the angular 1.5 code I found for factory:

var needsRecurse = false;
    var destination = copyType(source);

    if (destination === undefined) {
      destination = isArray(source) ? [] : Object.create(getPrototypeOf(source));
      needsRecurse = true;
    }

Angular source code snippet for the factory() function:

 function factory(name, factoryFn, enforce) {
    return provider(name, {
      $get: enforce !== false ? enforceReturnValue(name, factoryFn) : factoryFn
    });
  }

It takes the name and the factory function that is passed and returns a provider with the same name, that has a $get method which is our factory function. Whenever you ask the injector for a specific dependency, it basically asks the corresponding provider for an instance of that service, by calling the $get() method. That’s why $get() is required, when creating providers.

Here is the angular 1.5 code for service.

function service(name, constructor) {
    return factory(name, ['$injector', function($injector) {
      return $injector.instantiate(constructor);
    }]);
  }

It turns out that when we call service(), it actually calls factory()! However, it doesn’t just pass our service constructor function to the factory as is. It also passes a function that asks the injector to instantiate an object by the given constructor.

In other words, if we inject MyService somewhere, what happens in the code is:

MyServiceProvider.$get(); // return the instance of the service

To restate it again, a service calls a factory, which is a $get() method on the corresponding provider. Moreover, $injector.instantiate() is the method that ultimately calls Object.create() with the constructor function. That’s why we use "this" in services.

For ES5 it doesn't matter which we use: service() or factory(), it’s always a factory that is called which creates a provider for our service.

You can do the exact same thing with services as well though. A service is a constructor function, however, that doesn’t prevent us from returning object literals. So we can take our service code and write it in a way that it basically does the exact same thing as our factory or in other words, you can write a service as a factory to return an object.

Why do most people recommend to use factories over services? This is the best answer I've seen which comes from Pawel Kozlowski's book: Mastering Web Application Development with AngularJS.

The factory method is the most common way of getting objects into AngularJS dependency injection system. It is very flexible and can contain sophisticated creation logic. Since factories are regular functions, we can also take advantage of a new lexical scope to simulate "private" variables. This is very useful as we can hide implementation details of a given service."

use encodeURIComponent function to fix url, it works on Browser and node.js

res.redirect("/signin?email="+encodeURIComponent("[email protected]"));


> encodeURIComponent("http://a.com/a+b/c")
'http%3A%2F%2Fa.com%2Fa%2Bb%2Fc'

The simplest solution would be (using 'upstream' as the remote name referencing the original repo forked):

git remote add upstream /url/to/original/repo
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force 

(Similar to this GitHub page, section "What should I do if I’m in a bad situation?")

Be aware that you can lose changes done on the master branch (both locally, because of the reset --hard, and on the remote side, because of the push --force).

An alternative would be, if you want to preserve your commits on master, to replay those commits on top of the current upstream/master.
Replace the reset part by a git rebase upstream/master. You will then still need to force push.
See also "What should I do if I’m in a bad situation?"

A more complete solution, backing up your current work (just in case) is detailed in "Cleanup git master branch and move some commit to new branch".

See also "Pull new updates from original GitHub repository into forked GitHub repository" for illustrating what "upstream" is.

Note: recent GitHub repos do protect the master branch against push --force.
So you will have to un-protect master first (see picture below), and then re-protect it after force-pushing).

Note: on GitHub specifically, there is now (February 2019) a shortcut to delete forked repos for pull requests that have been merged upstream.

Nothing as useful as this: Common Data Structure Operations:

To add exact fontsize you can use following. Worked for me since in my case predefined ranges (Large, tiny) are not match with the font size required to me.

\fontsize{10}{12}\selectfont This is the text you need to be in 10px

More info: https://tug.org/TUGboat/tb33-3/tb105thurnherr.pdf

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

To ignore:

git update-index --assume-unchanged <path/to/file>

To undo ignore:

git update-index --no-assume-unchanged <path/to/file>

Edit: As of 0.1.8 this is now supported in the IDE. Please follow the instructions in there, instead of using the instructions below.

Following the Android Gradle Plugin User Guide I was able to get tests working on the command line by performing the following steps on a newly created project (I used the default 'com.example.myapplication' package):

1. Add a src/instrumentTest/java directory for the tests
2. Add a test class (extending ActivityTestCase) in the package com.example.myapplication.test
3. Start a virtual device
4. On the command line (in the MyApplicationProject/MyApplication directory) use the command '../gradlew connectedInstrumentTest'

This ran my tests and placed the test results in MyApplicationProject/MyApplication/build/reports/instrumentTests/connected. I'm new to testing Android apps, but it seem to work fine.

From within the IDE, it's possible to try and run the same test class. You'll need to

1. Update build.gradle to list Maven Central as a repo
2. Update build.gradle add JUnit 3.8 as a instrumentTestCompile dependency e.g. instrumentTestCompile 'junit:junit:3.8'
3. In 'Project Structure' manually move JUnit to be first in the dependency order

However this fails (the classpath used when running the tests is missing the test output directory). However, I'm not sure that this would work regardless as it's my understanding that an Android specific test runner is required.

I learned how to do these sort of things reading "PRO HTML and CSS Design Patterns". The display:block is the default display value for the div, but I like to make it explicit. The container has to be the right type; position attribute is fixed, relative, or absolute.

  display: block;_x000D_
  position:absolute;_x000D_
  height:auto;_x000D_
  bottom:0;_x000D_

  left:0;_x000D_
  right:0;_x000D_
  margin-top:20px;_x000D_
  margin-bottom:20px;_x000D_
  margin-right:80px;_x000D_
  margin-left:80px;_x000D_

You can fix this by adding this:

import { undefined } from 'undefined-is-a-function';
// Fixed! undefined is now a function.

^ is not the operator you want. You are looking for the pow function of java.lang.Math.

You can use Math.pow(value, power).

Example:

Math.pow(23, 5); // 23 to the fifth power

We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:

https://gitlab.example.com/<group>/<project>/commit/<commit hash>

We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.

to check out your PATH variable, act as follow:

1. From the Desktop, right-click My Computer and click Properties.
2. Click Advanced System Settings link in the left column.
3. In the System Properties window click the Environment Variables button.

Once there, scroll to get the Path row, you'll get a long string of paths (e.g. C:\windows\bin;C:\program files\git, etc)

Find the line or lines where git is referenced. Then, make sure this path point to your Git 1.8.x installation. If not, delete it and add the real path to the newest Git version. At the end, you should only have one path in the string linking to Git.

How you deal with this at the moment depends on what model you are using Linq to SQL or EntityFramework?

In L2S you can add

public partial class NWDataContext
{
    partial void InsertCategory(Category instance)
    {
        if(Instance.Date == null)
            Instance.Data = DateTime.Now;

        ExecuteDynamicInsert(instance);
    }
}

EF is a little more complicated see http://msdn.microsoft.com/en-us/library/cc716714.aspx for more info on EF buisiness logic.

Guessing from your directory name, you are trying to access the repository on the local filesystem. You still need to use URL syntax to access it:

svn export file:///e:/repositories/process/test.txt c:\test.txt

Thanks.I changed heap space from 2000MB to 1024MB and it worked...

I've coded up a simple example for you and annotated the source. The example shows how to grab live json and parse into a JSONObject for detail extraction:

try{
    // Create a new HTTP Client
    DefaultHttpClient defaultClient = new DefaultHttpClient();
    // Setup the get request
    HttpGet httpGetRequest = new HttpGet("http://example.json");

    // Execute the request in the client
    HttpResponse httpResponse = defaultClient.execute(httpGetRequest);
    // Grab the response
    BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
    String json = reader.readLine();

    // Instantiate a JSON object from the request response
    JSONObject jsonObject = new JSONObject(json);

} catch(Exception e){
    // In your production code handle any errors and catch the individual exceptions
    e.printStackTrace();
}

Once you have your JSONObject refer to the SDK for details on how to extract the data you require.

You should specify formGroupName for nested controls

<div class="panel panel-default" formGroupName="address"> <== add this

            document.querySelector(this.getAttribute('href')).scrollIntoView({
                behavior: 'smooth'
            });
        });
    });

I would like to share this answer I found because the cause of the problem was not the firewall or the process not listening correctly, it was the code sample provided from Microsoft that I used.

https://msdn.microsoft.com/en-us/library/system.net.sockets.socket%28v=vs.110%29.aspx

I implemented this function almost exactly as written, but what happened is I got this error:

2016-01-05 12:00:48,075 [10] ERROR - The error is: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it [fe80::caa:745:a1da:e6f1%11]:4080

This code would say the socket is connected, but not under the correct IP address actually needed for proper communication. (Provided by Microsoft)

private static Socket ConnectSocket(string server, int port)
    {
        Socket s = null;
        IPHostEntry hostEntry = null;

        // Get host related information.
        hostEntry = Dns.GetHostEntry(server);

        // Loop through the AddressList to obtain the supported AddressFamily. This is to avoid
        // an exception that occurs when the host IP Address is not compatible with the address family
        // (typical in the IPv6 case).
        foreach(IPAddress address in hostEntry.AddressList)
        {
            IPEndPoint ipe = new IPEndPoint(address, port);
            Socket tempSocket = 
                new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

            tempSocket.Connect(ipe);

            if(tempSocket.Connected)
            {
                s = tempSocket;
                break;
            }
            else
            {
                continue;
            }
        }
        return s;
    }

I re-wrote the code to just use the first valid IP it finds. I am only concerned with IPV4 using this, but it works with localhost, 127.0.0.1, and the actually IP address of you network card, where the example provided by Microsoft failed!

    private Socket ConnectSocket(string server, int port)
    {
        Socket s = null;

        try
        {
            // Get host related information.
            IPAddress[] ips;
            ips = Dns.GetHostAddresses(server);

            Socket tempSocket = null;
            IPEndPoint ipe = null;

            ipe = new IPEndPoint((IPAddress)ips.GetValue(0), port);
            tempSocket = new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

            Platform.Log(LogLevel.Info, "Attempting socket connection to " + ips.GetValue(0).ToString() + " on port " + port.ToString());
            tempSocket.Connect(ipe);

            if (tempSocket.Connected)
            {
                s = tempSocket;
                s.SendTimeout = Coordinate.HL7SendTimeout;
                s.ReceiveTimeout = Coordinate.HL7ReceiveTimeout;
            }
            else
            {
                return null;
            }

            return s;
        }
        catch (Exception e)
        {
            Platform.Log(LogLevel.Error, "Error creating socket connection to " + server + " on port " + port.ToString());
            Platform.Log(LogLevel.Error, "The error is: " + e.ToString());
            if (g_NoOutputForThreading == false)
                rtbResponse.AppendText("Error creating socket connection to " + server + " on port " + port.ToString());
            return null;
        }
    }

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

DATEPART function doesn't work on MySQL 5.6, instead use MONTH('2018-01-01')

As discussed in the comments, this can be achieved by converting the entry into Date format and extracting the year, for instance like this:

format(as.Date(df1$Date, format="%d/%m/%Y"),"%Y")

Potentially for a different question, but I'm providing my version of @Alvero's answer (using unidecode). I want to do a "regular" strip on my strings, i.e. the beginning and end of my string for whitespace characters, and then replace only other whitespace characters with a "regular" space, i.e.

"Ceñía?mañana????"

to

"Ceñía mañana"

,

def safely_stripped(s: str):
    return ' '.join(
        stripped for stripped in
        (bit.strip() for bit in
         ''.join((c if unidecode(c) else ' ') for c in s).strip().split())
        if stripped)

We first replace all non-unicode spaces with a regular space (and join it back again),

''.join((c if unidecode(c) else ' ') for c in s)

And then we split that again, with python's normal split, and strip each "bit",

(bit.strip() for bit in s.split())

And lastly join those back again, but only if the string passes an if test,

' '.join(stripped for stripped in s if stripped)

And with that, safely_stripped('????Ceñía?mañana????') correctly returns 'Ceñía mañana'.

We had this case where an .html file was seen as binary whenever we tried to make changes in it. Very uncool to not see diffs. To be honest, I didn't checked all the solutions here but what worked for us was the following:

1. Removed the file (actually moved it to my Desktop) and commited the git deletion. Git says Deleted file with mode 100644 (Regular) Binary file differs
2. Re-added the file (actually moved it from my Desktop back into the project). Git says New file with mode 100644 (Regular) 1 chunk, 135 insertions, 0 deletions The file is now added as a regular text file

From now on, any changes I made in the file is seen as a regular text diff. You could also squash these commits (1, 2, and 3 being the actual change you make) but I prefer to be able to see in the future what I did. Squashing 1 & 2 will show a binary change.

The issue caused by the docker container which exits as soon as the "start" process finishes. i added a command that runs forever and it worked. This issue mentioned here

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:
http://www.sublimetext.com/forum/viewtopic.php?f=3&p=42052
This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.

Another website that lists great monospaced free fonts for programmers. http://hivelogic.com/articles/top-10-programming-fonts

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

For me I just noticed that it was my .h archive with a '{'. Maye that can help someone =)

Expanding on First Zero's answer, I'm guess you want something where you can also run gradle build without errors.

Both gradle build and gradle -PmainClass=foo runApp work with this:

task runApp(type:JavaExec) {
    classpath = sourceSets.main.runtimeClasspath

    main = project.hasProperty("mainClass") ? project.getProperty("mainClass") : "package.MyDefaultMain"
}

where you set your default main class.

The new Selenium IDE (released in 2019) has a much broader API and new documentation.

The reason is mips are deprecated in the latest ndk versions, Gradle version 3.1.2 will not have a compulsion for mips. It assumes the presence for these missing folders.

Here is a solution to prevent session shearing between browser tabs for a java application. This will work for IE (JSP/Servlet)

1. In your first JSP page, onload event call a servlet (ajex call) to setup a "window.title" and event tracker in the session(just a integer variable to be set as 0 for first time)
2. Make sure none of the other pages set a window.title
3. All pages (including the first page) add a java script to check the window title once the page load is complete. if the title is not found then close the current page/tab(make sure to undo the "window.unload" function when this occurs)
4. Set page window.onunload java script event(for all pages) to capture the page refresh event, if a page has been refreshed call the servlet to reset the event tracker.

1)first page JS

BODY onload="javascript:initPageLoad()"

function initPageLoad() {
    var xmlhttp;

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {                           var serverResponse = xmlhttp.responseText;
            top.document.title=serverResponse;
        }
    };
                xmlhttp.open("GET", 'data.do', true);
    xmlhttp.send();

}

2)common JS for all pages

window.onunload = function() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {             
            var serverResponse = xmlhttp.responseText;              
        }
    };

    xmlhttp.open("GET", 'data.do?reset=true', true);
    xmlhttp.send();
}

var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
    init();
    clearInterval(readyStateCheckInterval);
}}, 10);
function init(){ 
  if(document.title==""){   
  window.onunload=function() {};
  window.open('', '_self', ''); window.close();
  }
 }

3)web.xml - servlet mapping

<servlet-mapping>
<servlet-name>myAction</servlet-name>
<url-pattern>/data.do</url-pattern>     
</servlet-mapping>  
<servlet>
<servlet-name>myAction</servlet-name>
<servlet-class>xx.xxx.MyAction</servlet-class>
</servlet>

4)servlet code

public class MyAction extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException {
    Integer sessionCount = (Integer) request.getSession().getAttribute(
            "sessionCount");
    PrintWriter out = response.getWriter();
    Boolean reset = Boolean.valueOf(request.getParameter("reset"));
    if (reset)
        sessionCount = new Integer(0);
    else {
        if (sessionCount == null || sessionCount == 0) {
            out.println("hello Title");
            sessionCount = new Integer(0);
        }
                          sessionCount++;
    }
    request.getSession().setAttribute("sessionCount", sessionCount);
    // Set standard HTTP/1.1 no-cache headers.
    response.setHeader("Cache-Control", "private, no-store, no-cache, must-                      revalidate");
    // Set standard HTTP/1.0 no-cache header.
    response.setHeader("Pragma", "no-cache");
} 
  }

First of all, checked can have a value of checked, or an empty string.

$("input:checkbox").uniform();

$('#check1').live('click', function() {
    $('#check2').attr('checked', 'checked').uniform();
});

I have written a quick example to demonstrate how to create a layout programmatically.

public class CodeLayout extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Creating a new RelativeLayout
        RelativeLayout relativeLayout = new RelativeLayout(this);

        // Defining the RelativeLayout layout parameters.
        // In this case I want to fill its parent
        RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.FILL_PARENT);

        // Creating a new TextView
        TextView tv = new TextView(this);
        tv.setText("Test");

        // Defining the layout parameters of the TextView
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);
        lp.addRule(RelativeLayout.CENTER_IN_PARENT);

        // Setting the parameters on the TextView
        tv.setLayoutParams(lp);

        // Adding the TextView to the RelativeLayout as a child
        relativeLayout.addView(tv);

        // Setting the RelativeLayout as our content view
        setContentView(relativeLayout, rlp);
    }
}

In theory everything should be clear as it is commented. If you don't understand something just tell me.

I wrote extension method

public static string ToMatrixString<T>(this T[,] matrix, string delimiter = "\t")
{
    var s = new StringBuilder();

    for (var i = 0; i < matrix.GetLength(0); i++)
    {
        for (var j = 0; j < matrix.GetLength(1); j++)
        {
            s.Append(matrix[i, j]).Append(delimiter);
        }

        s.AppendLine();
    }

    return s.ToString();
}

To use just call the method

results.ToMatrixString();

How to fade borders with CSS:

<div style="border-style:solid;border-image:linear-gradient(red, transparent) 1;border-bottom:0;">Text</div>

Please excuse the inline styles for the sake of demonstration. The 1 property for the border-image is border-image-slice, and in this case defines the border as a single continuous region.

Your example works for conditioned classes (the class name will show if the expressionDataX is true):

<div ng-class="{class1: expressionData1, class2: expressionData2}"></div>

You can also add multiple classes, supplied by the user of the element:

<div ng-class="[class1, class2]"></div>

Usage:

<div class="foo bar" class1="foo" class2="bar"></div>

I would prefer to see the use of a css class here. It avoids having hard to read colors / hex codes in javascript.

document.body.className = className;

It's simpler if you modify your HTML a little bit:

<label for="first_name">First Name</label>
<input type="text" id="name" name="name" />

<label for="surname">Surname</label>
<input type="text" id="surname" name="surname" />

<label for="firstname">Firstname</label>
<input type="text" id="firstname" name="firstname" disabled="disabled" />

then it's relatively simple

$(document).ready(function() { 
    $('#name').change(function() {
      $('#firstname').val($('#name').val());
    });
});

Multi joins in SQL work by progressively creating derived tables one after the other. See this link explaining the process:

This is a big gray area in cookie SOP (Same Origin Policy).

Theoretically, you can specify port number in the domain and the cookie will not be shared. In practice, this doesn't work with several browsers and you will run into other issues. So this is only feasible if your sites are not for general public and you can control what browsers to use.

The better approach is to get 2 domain names for the same IP and not relying on port numbers for cookies.

You are running Composer with SSL/TLS protection disabled.

In Matlab, you can iterate over the elements in the list directly. This can be useful if you don't need to know which element you're currently working on.

Thus you can write

for elm = list
%# do something with the element
end

Note that Matlab iterates through the columns of list, so if list is a nx1 vector, you may want to transpose it.

I recently run into the same problem. I solved it by implementing my own ImageView class.

Here is my Kotlin implementation:

class MyImageView(context: Context): ImageView(context) {
    private var currentDrawableId: Int? = null

    override fun setImageResource(resId: Int) {
        super.setImageResource(resId)
        currentDrawableId = resId
    }

    fun getDrawableId() {
        return currentDrawableId
    }

    fun compareCurrentDrawable(toDrawableId: Int?): Boolean {
        if (toDrawableId == null || currentDrawableId != toDrawableId) {
            return false
        }

        return true
    }

}

Instead of passing the properties as an argument, you may use a .properties for storing them.

If the string is already in list format, you can use the JSON.parse:

var a = "['a', 'b', 'c']";
a = a.replace(/'/g, '"');
a = JSON.parse(a);

Just to add to the thread as a POSSIBLE solution, I faced a similar issue when developing on a Linux system that was behind a company firewall. However, using a Windows XP machine, Eclipse was able to access different update sites just fine as both the manual and native network connection providers worked just fine using the company proxy.

After stumbling around for some time, I came across a discussion about using NTLMv2 and an implementation to be found at http://cntlm.sourceforge.net/. To whomever posted this, I give much credit to as it helped me get past the issue running on Linux. As a side note, I was using Eclipse 3.6.2 / Helios on both the Linux and Windows distros.

Best of luck on finding a solution!

The easiest solution to animate the DOM elements is using CSS transitions/animations but I think you already know that and you try to use canvas to do stuff CSS doesn't let you to do. What about CSS custom filters? you can transform your elements in any imaginable way if you know how to write shaders. Some other link and don't forget to check the CSS filter lab.
Note: As you can probably imagine browser support is bad.

If none of this did not help, then try to swap ^ in "^version" to ~ "~version".

I had a table change and it created another entity with a number 1 at the end (such as MyEntity1 and a MyEntity) as confirmed by the edmx model browser. Something about the two entities together confused the processing.

Removal of the table and re-adding it fixed it.

Note that if TFS is hooked up, then do a check-in of the edmx in after the delete. Then and only then get the latest and re-add it in a definite two step process. Otherwise TFS gets confused with the delete and re-add of same named entity(ies) which seems to cause problems.

in /etc/my.cnf:

[mysqld]
...

performance_schema = 0

table_cache = 0
table_definition_cache = 0
max-connect-errors = 10000

query_cache_size = 0
query_cache_limit = 0

...

Good work on server with 256MB Memory.

Note, that starting from PostgreSQL 8.4 you can get all information about sequences used in the database via:

SELECT * FROM information_schema.sequences;

Since I'm using a higher version of PostgreSQL (9.1), and was searching for same answer high and low, I added this answer for posterity's sake and for future searchers.

I can tell you from personal experience this is a bad idea. Native Windows programs cannot accept Cygwin paths. For example with Cygwin you might run a command

grep -r --color foo /opt

with no issue. With Cygwin / represents the root directory. Native Windows programs have no concept of this, and will likely fail if invoked this way. You should not mix Cygwin and Native Windows programs unless you have no other choice.

Uninstall what Git you have and install the Cygwin git package, save yourself the headache.

I'd suggest following a few debugging steps.

First run the query directly against the DB. Confirm it is bringing results back. Even with something as simple as this you can find you've made a mistake, or the table is empty, or somesuch oddity.

If the above is ok, then try looping and echoing out the contents of $row just directly into the HTML to see what you've getting back in the mysql_query - see if it matches what you got directly in the DB.

If your data is output onto the page, then look at what's going wrong in your HTML formatting.

However, if nothing is output from $row, then figure out why the mysql_query isn't working e.g. does the user have permission to query that DB, do you have an open DB connection, can the webserver connect to the DB etc [something on these lines can often be a gotcha]

Changing your query slightly to

$sql = mysql_query("SELECT username FROM users") or die(mysql_error());  

may help to highlight any errors: php manual

You can use either jQuery Autocomplete or ASP.NET AJAX Toolkit Autocomplete

For a variable number of arguments like this the only way I'm aware of is to either generate the SQL explicitly or do something that involves populating a temporary table with the items you want and joining against the temp table.

Use the preprocessor # operator:

#define CALL_DO_SOMETHING(VAR) do_something(#VAR, VAR);

If you need a CakePHP Docker Container with MySQL, I have created a Docker image for that purpose! No need to worry about setting it up. It just works!

• GitHub: https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker
• DockerHub: https://hub.docker.com/r/marcellodesales/php-apache-cakephp-mysql/

Here's how I installed in Ubuntu-based image:

https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker/blob/master/Dockerfile#L8

RUN docker-php-ext-install mysql mysqli pdo pdo_mysql

Building and running your application is just a 2 step process (considering you are in the current directory of the app):

$ docker build -t myCakePhpApp .
$ docker run -ti myCakePhpApp

I was dealing with DateTimeOffset and unfortunately the "o" prints out "+0000" not "Z".

So I ended up with:

dateTimeOffset.UtcDateTime.ToString("o")

I solved it this way: download the zipped package from here and follow this set of instructions:

unzip  /path/to/downloads/folder/mysql-connector-python-VER.zip  

In case u got a .gz u can use ->

tar xzf mysql-connector-python-VER.tar.gz 

And then:

cd mysql-connector-python-VER  # move into the directory

sudo python3 setup.py install # NOTICE I USED PYTHON3 INSTEAD OF PYTHON

You can read about it here

As described here, you can also attempt the command

npm cache clean

That fixed it for me, after the other steps had not fully yielded results (other than updating everything).

You can view these with Process Explorer from sysinternals. Use the "Find -> Find Handle or DLL..." option and enter the pattern "\Device\NamedPipe\". It will show you which processes have which pipes open.

If boolean() is not available (the tool I'm using does not) one way to achieve it is:

//SELECT[@id='xpto']/OPTION[not(not(@selected))]

In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.

The method setAlpha(int) from the type ImageView is deprecated.

Instead of

image.setImageAlpha(127);
//value: [0-255]. Where 0 is fully transparent and 255 is fully opaque.

PS> I posted this answer on a related question. Here's how I got round the issue of my async ajax request losing the trusted context:

I opened the popup directly on the users click, directed the url to about:blank and got a handle on that window. You could probably direct the popup to a 'loading' url while your ajax request is made

var myWindow = window.open("about:blank",'name','height=500,width=550');

Then, when my request is successful, I open my callback url in the window

function showWindow(win, url) {
     win.open(url,'name','height=500,width=550');
}

try the below one. it will give ur expected output

select c.name as Fields from 
tempdb.sys.columns c
    inner join tempdb.sys.tables t
 ON c.object_id = t.object_id
where t.name like '#MyTempTable%'

instead of id use title to identify your element and write the code as below.

$(document).ready(()=>{

 $("input[title='MyObject']").change(()=>{
        console.log("Field has been changed...")
    })  
});

You could also have a look at testing using Groovy. In Groovy you can easily mock Java interfaces using the 'as' operator:

def request = [isUserInRole: { roleName -> roleName == "testRole"}] as HttpServletRequest 

Apart from this basic functionality Groovy offers a lot more on the mocking front, including the powerful MockFor and StubFor classes.

Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));

https://developer.mozilla.org/en/CSS/Media_queries#-moz-device-pixel-ratio

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.

this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

I have found Adobe Dreamweaver to be quite good at that. However, it's not free.

Try to change where Member class

public function users() {
    return $this->hasOne('User');
} 

return $this->belongsTo('User');

Mutable means you will save the same reference to variable and change its contents but immutable you can not change contents but you will declare new reference contains the new and the old value of the variable

Ex Immutable -> String

String x = "value0ne";// adresse one x += "valueTwo"; //an other adresse {adresse two} adresse on the heap memory change.

Mutable -> StringBuffer - StringBuilder StringBuilder sb = new StringBuilder(); sb.append("valueOne"); // adresse One sb.append("valueTwo"); // adresse One

sb still in the same adresse i hope this comment helps

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList instead of array:

List<Car> garage = new ArrayList<Car>();
garage.add(redCar);

If your modal div is dynamically added then use( For bootstrap 3 and 4)

$(document).on('hide.bs.modal','#modal-id', function () {
                alert('');
 //Do stuff here
});

This will work for non-dynamic content also.

This one-liner tells where the shell script is, does not matter if you ran it or if you sourced it. Also, it resolves any symbolic links involved, if that is the case:

dir=$(dirname $(test -L "$BASH_SOURCE" && readlink -f "$BASH_SOURCE" || echo "$BASH_SOURCE"))

By the way, I suppose you are using /bin/bash.

Assuming you have some level of control over the protocol, I'm a big fan of sending heartbeats to verify that a connection is active. It's proven to be the most fail proof method and will often give you the quickest notification when a connection has been broken.

TCP keepalives will work, but what if the remote host is suddenly powered off? TCP can take a long time to timeout. On the other hand, if you have logic in your app that expects a heartbeat reply every x seconds, the first time you don't get them you know the connection no longer works, either by a network or a server issue on the remote side.

See Do I need to heartbeat to keep a TCP connection open? for more discussion.

If you need to store a member function without the class instance, you can do something like this:

class MyClass
{
public:
    void MemberFunc(int value)
    {
      //do something
    }
};

// Store member function binding
auto callable = std::mem_fn(&MyClass::MemberFunc);

// Call with late supplied 'this'
MyClass myInst;
callable(&myInst, 123);

What would the storage type look like without auto? Something like this:

std::_Mem_fn_wrap<void,void (__cdecl TestA::*)(int),TestA,int> callable

You can also pass this function storage to a standard function binding

std::function<void(int)> binding = std::bind(callable, &testA, std::placeholders::_1);
binding(123); // Call

Past and future notes: An older interface std::mem_func existed, but has since been deprecated. A proposal exists, post C++17, to make pointer to member functions callable. This would be most welcome.

you can also mark the application as private if you don’t plan to put it in an actual repository.

{
  "name": "my-application",
  "version": "0.0.1",
  "private": true
}

This actually works for me:

Per the README.SSO that comes with the jtdsd distribution:

In order for Single Sign On to work, jTDS must be able to load the native SPPI library ntlmauth.dll. Place this DLL anywhere in the system path (defined by the PATH system variable) and you're all set.

I placed it in my jre/bin folder

The WHY: dates are objects

In Python, dates are objects. Therefore, when you manipulate them, you manipulate objects, not strings or timestamps.

Any object in Python has TWO string representations:

• The regular representation that is used by print can be get using the str() function. It is most of the time the most common human readable format and is used to ease display. So str(datetime.datetime(2008, 11, 22, 19, 53, 42)) gives you '2008-11-22 19:53:42'.

• The alternative representation that is used to represent the object nature (as a data). It can be get using the repr() function and is handy to know what kind of data your manipulating while you are developing or debugging. repr(datetime.datetime(2008, 11, 22, 19, 53, 42)) gives you 'datetime.datetime(2008, 11, 22, 19, 53, 42)'.

What happened is that when you have printed the date using print, it used str() so you could see a nice date string. But when you have printed mylist, you have printed a list of objects and Python tried to represent the set of data, using repr().

The How: what do you want to do with that?

Well, when you manipulate dates, keep using the date objects all long the way. They got thousand of useful methods and most of the Python API expect dates to be objects.

When you want to display them, just use str(). In Python, the good practice is to explicitly cast everything. So just when it's time to print, get a string representation of your date using str(date).

One last thing. When you tried to print the dates, you printed mylist. If you want to print a date, you must print the date objects, not their container (the list).

E.G, you want to print all the date in a list :

for date in mylist :
    print str(date)

Note that in that specific case, you can even omit str() because print will use it for you. But it should not become a habit :-)

Practical case, using your code

import datetime
mylist = []
today = datetime.date.today()
mylist.append(today)
print mylist[0] # print the date object, not the container ;-)
2008-11-22

# It's better to always use str() because :

print "This is a new day : ", mylist[0] # will work
>>> This is a new day : 2008-11-22

print "This is a new day : " + mylist[0] # will crash
>>> cannot concatenate 'str' and 'datetime.date' objects

print "This is a new day : " + str(mylist[0]) 
>>> This is a new day : 2008-11-22

Advanced date formatting

Dates have a default representation, but you may want to print them in a specific format. In that case, you can get a custom string representation using the strftime() method.

strftime() expects a string pattern explaining how you want to format your date.

E.G :

print today.strftime('We are the %d, %b %Y')
>>> 'We are the 22, Nov 2008'

All the letter after a "%" represent a format for something:

• %d is the day number (2 digits, prefixed with leading zero's if necessary)
• %m is the month number (2 digits, prefixed with leading zero's if necessary)
• %b is the month abbreviation (3 letters)
• %B is the month name in full (letters)
• %y is the year number abbreviated (last 2 digits)
• %Y is the year number full (4 digits)

etc.

Have a look at the official documentation, or McCutchen's quick reference you can't know them all.

Since PEP3101, every object can have its own format used automatically by the method format of any string. In the case of the datetime, the format is the same used in strftime. So you can do the same as above like this:

print "We are the {:%d, %b %Y}".format(today)
>>> 'We are the 22, Nov 2008'

The advantage of this form is that you can also convert other objects at the same time.
With the introduction of Formatted string literals (since Python 3.6, 2016-12-23) this can be written as

import datetime
f"{datetime.datetime.now():%Y-%m-%d}"
>>> '2017-06-15'

Localization

Dates can automatically adapt to the local language and culture if you use them the right way, but it's a bit complicated. Maybe for another question on SO(Stack Overflow) ;-)

You can use modern Java to solve this problem. Please use the code below:

Obviously you can use maxLength in xml or InputFilter.LengthFilter as answered above. But for me in some cases, it was not enough. I created a class for more flexible settings of EditText: https://github.com/devapro/NumberWatcher It is implementation only for numbers input, but you can change it for any of the types.

AutoFilterMode will be True if engaged, regardless of whether there is actually a filter applied to a specific column or not. When this happens, ActiveSheet.ShowAllData will still run, throwing an error (because there is no actual filtering).

I had the same issue and got it working with

If (ActiveSheet.AutoFilterMode And ActiveSheet.FilterMode) Or ActiveSheet.FilterMode Then
  ActiveSheet.ShowAllData
End If

This seems to prevent ShowAllData from running when there is no actual filter applied but with AutoFilterMode turned on.

The second catch Or ActiveSheet.FilterMode should catch advanced filters

You'll be able to set and get cookies like this

docCookies.setItem(name, value);
docCookies.getItem(name);

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

The other one doesn't work. According to the docs this is the way you should do it.

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {

    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      resolve: {
        test: function () {
          return 'test variable';
        }
      }
    });
};

var ModalInstanceCtrl = function ($scope, $modalInstance, test) {

  $scope.test = test;
};

See plunkr

Have you tried the power button :) ... it really worked for me. Actually emulator saves the device state before closing so at the last run if you switched off the device & closed the emulator then in the next run it will load previous state & display switched off phone aka blank screen. Although there might be many other causes of this issue.

The javascript has

var canvasW     = 640;
var canvasH     = 480;

in it. Try changing those as well as the css for the canvas.

Or better yet, have the initialize function determine the size of the canvas from the css!

in response to your edits, change your init function:

function init()
{
    canvas = document.getElementById("mainCanvas");
    canvas.width = document.body.clientWidth; //document.width is obsolete
    canvas.height = document.body.clientHeight; //document.height is obsolete
    canvasW = canvas.width;
    canvasH = canvas.height;

    if( canvas.getContext )
    {
        setup();
        setInterval( run , 33 );
    }
}

Also remove all the css from the wrappers, that just junks stuff up. You have to edit the js to get rid of them completely though... I was able to get it full screen though.

html, body {
    overflow: hidden;
}

Edit: document.width and document.height are obsolete. Replace with document.body.clientWidth and document.body.clientHeight

this is my sample you can use:

        public static string GetFileNameValidChar(string fileName)
    {
        foreach (var item in System.IO.Path.GetInvalidFileNameChars())
        {
            fileName = fileName.Replace(item.ToString(), "");
        }
        return fileName;
    }

    public static string GetFileNameFromUrl(string url)
    {
        string fileName = "";
        if (Uri.TryCreate(url, UriKind.Absolute, out Uri uri))
        {
            fileName = GetFileNameValidChar(Path.GetFileName(uri.AbsolutePath));
        }
        string ext = "";
        if (!string.IsNullOrEmpty(fileName))
        {
            ext = Path.GetExtension(fileName);
            if (string.IsNullOrEmpty(ext))
                ext = ".html";
            else
                ext = "";
            return GetFileNameValidChar(fileName + ext);

        }

        fileName = Path.GetFileName(url);
        if (string.IsNullOrEmpty(fileName))
        {
            fileName = "noName";
        }
        ext = Path.GetExtension(fileName);
        if (string.IsNullOrEmpty(ext))
            ext = ".html";
        else
            ext = "";
        fileName = fileName + ext;
        if (!fileName.StartsWith("?"))
            fileName = fileName.Split('?').FirstOrDefault();
        fileName = fileName.Split('&').LastOrDefault().Split('=').LastOrDefault();
        return GetFileNameValidChar(fileName);
    }

Usage:

var fileName = GetFileNameFromUrl("http://cdn.p30download.com/?b=p30dl-software&f=Mozilla.Firefox.v58.0.x86_p30download.com.zip");

A percentage in the value of the font-size property is relative to the parent element’s font size. CSS 2.1 says this obscurely and confusingly (referring to “inherited font size”), but CSS3 Text says it very clearly.

The parent of the body element is the root element, i.e. the html element. Unless set in a style sheet, the font size of the root element is implementation-dependent. It typically depends on user settings.

Setting font-size: 100% is pointless in many cases, as an element inherits its parent’s font size (leading to the same result), if no style sheet sets its own font size. However, it can be useful to override settings in other style sheets (including browser default style sheets).

For example, an input element typically has a setting in browser style sheet, making its default font size smaller than that of copy text. If you wish to make the font size the same, you can set

input { font-size: 100% }

For the body element, the logically redundant setting font-size: 100% is used fairly often, as it is believed to help against some browser bugs (in browsers that probably have lost their significance now).

I suspect you are having a problem with factors. For example,

> x = factor(4:8)
> x
[1] 4 5 6 7 8
Levels: 4 5 6 7 8
> as.numeric(x)
[1] 1 2 3 4 5
> as.numeric(as.character(x))
[1] 4 5 6 7 8

Some comments:

• You mention that your vector contains the characters "Down" and "NoData". What do expect/want as.numeric to do with these values?
• In read.csv, try using the argument stringsAsFactors=FALSE
• Are you sure it's sep="/t and not sep="\t"
• Use the command head(pitchman) to check the first fews rows of your data
• Also, it's very tricky to guess what your problem is when you don't provide data. A minimal working example is always preferable. For example, I can't run the command pichman <- read.csv(file="picman.txt", header=TRUE, sep="/t") since I don't have access to the data set.

Your hosts file does not include a valid FQDN, nor is localhost an FQDN. An FQDN must include a hostname part, as well as a domain name part. For example, the following is a valid FQDN:

host.server4-245.com

Choose an FQDN and include it both in your /etc/hosts file on both the IPv4 and IPv6 addresses you are using (in your case, localhost or 127.0.0.1), and change your ServerName in your httpd configuration to match.

/etc/hosts:

127.0.0.1    localhost.localdomain localhost host.server4-245.com
::1          localhost.localdomain localhost host.server4-245.com

httpd.conf:

ServerName host.server4-245.com

You can use this: document.getElementById('h1_id').innerHTML = 'the new text';

Yes. You need to close the resultset, the statement and the connection. If the connection has come from a pool, closing it actually sends it back to the pool for reuse.

You typically have to do this in a finally{} block, such that if an exception is thrown, you still get the chance to close this.

Many frameworks will look after this resource allocation/deallocation issue for you. e.g. Spring's JdbcTemplate. Apache DbUtils has methods to look after closing the resultset/statement/connection whether null or not (and catching exceptions upon closing), which may also help.

Prerequisite:

Aria is used to improve the user experience of visually impaired users. Visually impaired users navigate though application using screen reader software like JAWS, NVDA,.. While navigating through the application, screen reader software announces content to users. Aria can be used to add content in the code which helps screen reader users understand role, state, label and purpose of the control

Aria does not change anything visually. (Aria is scared of designers too).

aria-label

aria-label attribute is used to communicate the label to screen reader users. Usually search input field does not have visual label (thanks to designers). aria-label can be used to communicate the label of control to screen reader users

How To Use:

<input type="edit" aria-label="search" placeholder="search">

There is no visual change in application. But screen readers can understand the purpose of control

aria-labelledby

Both aria-label and aria-labelledby is used to communicate the label. But aria-labelledby can be used to reference any label already present in the page whereas aria-label is used to communicate the label which i not displayed visually

Approach 1:

<span id="sd">Search</span>

<input type="text" aria-labelledby="sd">

Approach 2:

aria-labelledby can also be used to combine two labels for screen reader users

<span id="de">Billing Address</span>

<span id="sd">First Name</span>

<input type="text" aria-labelledby="de sd">

The approximate conversions are:

• Latitude: 1 deg = 110.574 km
• Longitude: 1 deg = 111.320*cos(latitude) km

This doesn't fully correct for the Earth's polar flattening - for that you'd probably want a more complicated formula using the WGS84 reference ellipsoid (the model used for GPS). But the error is probably negligible for your purposes.

Source: http://en.wikipedia.org/wiki/Latitude

Caution: Be aware that latlong coordinates are expressed in degrees, while the cos function in most (all?) languages typically accepts radians, therefore a degree to radians conversion is needed.

One more way:

git diff stash@{N}^! -- path/to/file1 path/to/file2  | git apply -R

You can just simply use Flexbox like this:

#outer {_x000D_
    display: flex;_x000D_
    justify-content: center_x000D_
}

<div id="outer">_x000D_
    <div id="inner">Foo foo</div>_x000D_
</div>

Apply Autoprefixer for all browser support:

#outer {
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    width: 100%;
    -webkit-box-pack: center;
    -ms-flex-pack: center;
    justify-content: center
}

Or else

Use transform:

#inner {_x000D_
    position: absolute;_x000D_
    left: 50%;_x000D_
    transform: translate(-50%)_x000D_
}

<div id="outer">_x000D_
    <div id="inner">Foo foo</div>_x000D_
</div>

With Autoprefixer:

#inner {
    position: absolute;
    left: 50%;
    -webkit-transform: translate(-50%);
    -ms-transform:     translate(-50%);
    transform:         translate(-50%)
}

This error can also happen if you pass a key word argument for which one of the keys is similar (has same string name) to a positional argument.

>>> class Foo():
...     def bar(self, bar, **kwargs):
...             print(bar)
... 
>>> kwgs = {"bar":"Barred", "jokes":"Another key word argument"}
>>> myfoo = Foo()
>>> myfoo.bar("fire", **kwgs)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: bar() got multiple values for argument 'bar'
>>> 

"fire" has been accepted into the 'bar' argument. And yet there is another 'bar' argument present in kwargs.

You would have to remove the keyword argument from the kwargs before passing it to the method.

A TCP/IP connection is always made to an IP address (you can think of an IP-address as the address of a certain computer, even if that is not always the case) and a specific (logical, not physical) port on that address.

Usually one port is coupled to a specific process or "service" on the target computer. Some port numbers are standardized, like 80 for http, 25 for smtp and so on. Because of that standardization you usually don't need to put port numbers into your web adresses.

So if you say something like http://www.stackoverflow.com, the part "stackoverflow.com" resolves to an IP address (in my case 64.34.119.12) and because my browser knows the standard it tries to connect to port 80 on that address. Thus this is the same as http://www.stackoverflow.com:80.

But there is nothing that stops a process to listen for http requests on another port, like 12434, 4711 or 8080. Usually (as in your case) this is used for debugging purposes to not intermingle with another process (like IIS) already listening to port 80 on the same machine.

Yes, you can do <property name="defaultLocale" value="#{ systemProperties['user.region']}"/> for instance.

The variable systemProperties is predefined, see 6.4.1 XML based configuration.

There are two things,

1) You can run the mongodb instance without username and password first.

2) Then you can add the user to the system database of the mongodb which is default one using the query below.

db.createUser({
  user: "myUserAdmin",
  pwd: "abc123",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})

Thanks.

You have a view model to which your view is strongly typed => use strongly typed helpers:

<%= Html.DropDownListFor(
    x => x.SelectedAccountId, 
    new SelectList(Model.Accounts, "Value", "Text")
) %>

Also notice that I use a SelectList for the second argument.

And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:

public ActionResult AccountTransaction()
{
    var accounts = Services.AccountServices.GetAccounts(false);
    var viewModel = new AccountTransactionView
    {
        Accounts = accounts.Select(a => new SelectListItem
        {
            Text = a.Description,
            Value = a.AccountId.ToString()
        })
    };
    return View(viewModel);
}

I just closed all the files and reopened them, and voila!!! Hope this helps someone in the future ;)

I had this issue when my appdelegate class was not linked against my main app target but a separate static framework. Linking it directly against the target app fixed the issue.

This is what has worked for me in order to disable CORS between Spring boot and React

@Configuration
public class CorsConfig implements WebMvcConfigurer {

    /**
     * Overriding the CORS configuration to exposed required header for ussd to work
     *
     * @param registry CorsRegistry
     */

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("*")
                .allowedHeaders("*")
                .allowCredentials(true)
                .maxAge(4800);
    }
}

I had to modify the Security configuration also like below:

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable()
                    .cors().configurationSource(new CorsConfigurationSource() {

                @Override
                public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
                    CorsConfiguration config = new CorsConfiguration();
                    config.setAllowedHeaders(Collections.singletonList("*"));
                    config.setAllowedMethods(Collections.singletonList("*"));
                    config.addAllowedOrigin("*");
                    config.setAllowCredentials(true);
                    return config;
                }
            }).and()
                    .antMatcher("/api/**")
                    .authorizeRequests()
                    .anyRequest().authenticated()
                    .and().httpBasic()
                    .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    .and().exceptionHandling().accessDeniedHandler(apiAccessDeniedHandler());
        }

sourceString.Replace(removeString, "");

how about

echo $list | grep -w -q $x

you could either check the output or $? of above line to make the decision.

grep -w checks on whole word patterns. Adding -q prevents echoing the list.

In that case, you don't need to use angular.copy()

Explanation :

• = represents a reference whereas angular.copy() creates a new object as a deep copy.

• Using = would mean that changing a property of response.data would change the corresponding property of $scope.example or vice versa.

• Using angular.copy() the two objects would remain seperate and changes would not reflect on each other.

Use the vbcrlf for new line in SSSR. e.g.

= First(Fields!SAPName.Value, "DataSet1") & vbcrlf & First(Fields!SAPStreet.Value, "DataSet1") & vbcrlf & First(Fields!SAPCityPostal.Value, "DataSet1") & vbcrlf & First(Fields!SAPCountry.Value, "DataSet1") 

If you need to create a user_id then it would be a reasonable assumption that you are referencing a user table. In which case the migration shall be:

rails generate migration AddUserRefToProducts user:references

This command will generate the following migration:

class AddUserRefToProducts < ActiveRecord::Migration
  def change
    add_reference :user, :product, index: true
  end
end

After running rake db:migrate both a user_id column and an index will be added to the products table.

In case you just need to add an index to an existing column, e.g. name of a user table, the following technique may be helpful:

rails generate migration AddIndexToUsers name:string:index will generate the following migration:

class AddIndexToUsers < ActiveRecord::Migration
  def change
    add_column :users, :name, :string
    add_index :users, :name
  end
end

Delete add_column line and run the migration.

In the case described you could have issued rails generate migration AddIndexIdToTable index_id:integer:index command and then delete add_column line from the generated migration. But I'd rather recommended to undo the initial migration and add reference instead:

rails generate migration RemoveUserIdFromProducts user_id:integer
rails generate migration AddUserRefToProducts user:references

DirectoryIndex index.html index.htm default.htm index.php index.php3 index.phtml index.php5 index.shtml mwindex.phtml

it doesn't has any means? you may be just need to add like this!

<IfModule dir_module>
    DirectoryIndex index.php index.html index.htm
</IfModule>

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

the first way is better, the second way cost more time on creating a new array and converting to a list

Include <%@ page isELIgnored="false"%> on top of your jsp page.

This is how I do it:

std::string removeAll(std::string str, char c) {
    size_t offset = 0;
    size_t size = str.size();

    size_t i = 0;
    while (i < size - offset) {
        if (str[i + offset] == c) {
            offset++;
        }

        if (offset != 0) {
            str[i] = str[i + offset];
        }

        i++;
    }

    str.resize(size - offset);
    return str;
}

Basically whenever I find a given char, I advance the offset and relocate the char to the correct index. I don't know if this is correct or efficient, I'm starting (yet again) at C++ and i'd appreciate any input on that.

'so many subjective answers to an objective question. "Unobtrusive" JavaScript is superstition like the old rule to never use gotos. Write code in a way that helps you reliably accomplish your goal, not according to someone's trendy religious beliefs.

Anyone who finds:

 <body onload="body_onload();">

to be overly distracting is overly pretentious and doesn't have their priorities straight.

I normally put my JavaScript code in a separate .js file, but I find nothing cumbersome about hooking event handlers in HTML, which is valid HTML by the way.

This worked for me.

<table>
  <tr>
    <td *ngFor="#group of groups">
       <h1>{{group.name}}</h1>
   </td>
  </tr>
</table>

I am trying to do that in jQuery 2.1, and with the "$().click() -> $(element).data("events").click;" method it doesn't work.

I realized that only the $._data() functions works in my case :

 $(document).ready(function(){_x000D_
_x000D_
  var node = $('body');_x000D_

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

document.location isn't a string.

You're probably wanting to use document.location.href or document.location.pathname instead.

If you want them to be displayed side by side, why is sideContent the child of mainContent? make them siblings then use:

float:left; display:inline; width: 49%;

on both of them.

#mainContent, #sideContent {float:left; display:inline; width: 49%;}

It is not (with current browsers) possible to make an input field read-only through CSS alone.

Though, as you have already mentioned, you can apply the attribute readonly='readonly'.

If your main criteria is to not alter the markup in the source, there are ways to get this in, unobtrusively, with javascript.

With jQuery, this is easy:

 $('input').attr('readonly', true);

Or even with plain Javascript:

document.getElementById('someId').setAttribute('readonly', 'readonly');

Bootstrap rows always contain their floats and create new lines. You don't need to worry about filling blank columns, just make sure they don't add up to more than 12.

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">_x000D_
_x000D_
<div class="container">_x000D_
  <div class="row">_x000D_
    <div class="col-xs-3 col-xs-offset-9">_x000D_
      I'm a right column of 3_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="row">_x000D_
    <div class="col-xs-3">_x000D_
      I'm a left column of 3_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="panel panel-default">_x000D_
    <div class="panel-body">_x000D_
      And I'm some content below both columns_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

You can also take advantage of the fact that a lambda or anonymous method can close over variables in its enclosing scope.

MyType result;

SimpleUsing.DoUsing(db => 
{
  result = db.SomeQuery(); //whatever returns the MyType result
}); 

//do something with result

I'd add Commons NullComparator instead to avoid some problems...

You could find the difference between dates in columns in a data frame by using the function difftime as follows:

df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))

The slightly modified version of COPY below worked better for me, where I specify the CSV format. This format treats backslash characters in text without any fuss. The default format is the somewhat quirky TEXT.

COPY myTable FROM '/path/to/file/on/server' ( FORMAT CSV, DELIMITER('|') );

Try with this one:

$(document).ready(function(){
  $('a').click(function(e){
     e.preventDefault();
     $("#content").load($(this).attr('href'));
  });
});

and make sure to call this library first:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">
</script>

While agf was right with the answer in the past, now with PEP-3124 we got our syntactic sugar.

See typing documentation for details on the @overload decorator, but note that this is really just syntactic sugar and IMHO this is all people have been arguing about ever since.

Personally, I agree that having multiple functions with different signatures makes it more readable then having a single function with 20+ arguments all set to a default value (None most of the time) and then having to fiddle around using endless if, elif, else chains to find out what the caller actually wants our function to do with the provided set of arguments. This was long overdue following the Python Zen:

Beautiful is better than ugly.

and arguably also

Simple is better than complex.

Straight from the official Python documentation linked above:

from typing import overload
@overload
def process(response: None) -> None:
    ...
@overload
def process(response: int) -> Tuple[int, str]:
    ...
@overload
def process(response: bytes) -> str:
    ...
def process(response):
    <actual implementation>

For those who (unlike OP) are using the express lib:

http.get('*',function(req,res){  
    res.redirect('http://exmple.com'+req.url)
})

Since I never can remember that LINQ calls it Where, Select and Aggregate instead of Filter, Map and Reduce so I created a few extension methods you can use:

IEnumerable<string> myStrings = new List<string>() { "1", "2", "3", "4", "5" };
IEnumerable<int> convertedToInts = myStrings.Map(s => int.Parse(s));
IEnumerable<int> filteredInts = convertedToInts.Filter(i => i <= 3); // Keep 1,2,3
int sumOfAllInts = filteredInts.Reduce((sum, i) => sum + i); // Sum up all ints
Assert.Equal(6, sumOfAllInts); // 1+2+3 is 6

Here are the 3 methods (from https://github.com/cs-util-com/cscore/blob/master/CsCore/PlainNetClassLib/src/Plugins/CsCore/com/csutil/collections/IEnumerableExtensions.cs ):

public static IEnumerable<R> Map<T, R>(this IEnumerable<T> self, Func<T, R> selector) {
    return self.Select(selector);
}

public static T Reduce<T>(this IEnumerable<T> self, Func<T, T, T> func) {
    return self.Aggregate(func);
}

public static IEnumerable<T> Filter<T>(this IEnumerable<T> self, Func<T, bool> predicate) {
    return self.Where(predicate);
}

Hi recently looked into this and had issues referencing the named table (list object) within excel

if you place a suffix '$' on the table name all is well in the world

Sub testSQL()

    Dim cn As ADODB.Connection
    Dim rs As ADODB.Recordset

    ' Declare variables
    strFile = ThisWorkbook.FullName

    ' construct connection string
    strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile _
    & ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"

    ' create connection and recordset objects
    Set cn = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")

    ' open connection
    cn.Open strCon

    ' construct SQL query
    strSQL = "SELECT * FROM [TableName$] where [ColumnHeader] = 'wibble';"

    ' execute SQL query
    rs.Open strSQL, cn

    Debug.Print rs.GetString

    ' close connection
    rs.Close
    cn.Close
    Set rs = Nothing
    Set cn = Nothing
End Sub

I had the same problem, but caused by Homebrew:

[~]$ rbenv version
2.3.0 (set by /Users/user/.rbenv/version)
[~]$ ruby -v
ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-darwin16]
[~]$ which ruby
/usr/local/bin/ruby

Somehow I had installed Ruby via Homebrew too, and the Homebrew path was ahead of the rbenv path in my $PATH. Running brew uninstall ruby fixed it for me.

The connectivity: package does not guarantee the actual internet connection (could be just wifi connection without internet access).

Quote from the documentation:

Note that on Android, this does not guarantee connection to Internet. For instance, the app might have wifi access but it might be a VPN or a hotel WiFi with no access.

If you really need to check the connection to the www Internet the better choice would be

data_connection_checker package

The first four functions you list will work on vectors as well, with the exception that lower_wick needs to be adapted. Something like this,

def lower_wick_vec(o, l, c):
    min_oc = numpy.where(o > c, c, o)
    return min_oc - l

where o, l and c are vectors. You could do it this way instead which just takes the df as input and avoid using numpy, although it will be much slower:

def lower_wick_df(df):
    min_oc = df[['Open', 'Close']].min(axis=1)
    return min_oc - l

The other three will work on columns or vectors just as they are. Then you can finish off with

def is_hammer(df):
    lw = lower_wick_at_least_twice_real_body(df["Open"], df["Low"], df["Close"]) 
    cl = closed_in_top_half_of_range(df["High"], df["Low"], df["Close"])
    return cl & lw

Bit operators can perform set logic on boolean vectors, & for and, | for or etc. This is enough to completely vectorize the sample calculations you gave and should be relatively fast. You could probably speed up even more by temporarily working with the numpy arrays underlying the data while performing these calculations.

For the second part, I would recommend introducing a column indicating the pattern for each row and writing a family of functions which deal with each pattern. Then groupby the pattern and apply the appropriate function to each group.

I resolved this problem by following steps:

1. Right click on root folder of project.
2. Goto properties
3. Click web in left menu
4. change current port http://localhost:####/
5. click create virtual directory
6. Save the changes (ctrl+s)
7. Run

may be it help you to.

There is another library called arrow really great to make manipulation on python date.

import arrow
import datetime

a = arrow.get('24052010', 'DMYYYY').date()
print(isinstance(a, datetime.date)) # True

DISTINCT is the keyword
For me your query is correct

Just try to do this first

SELECT DISTINCT title,id FROM tbl_countries

Later on you can try with order by.

In Python, paths are relative to the current working directory, which in most cases is the directory from which you run your program. The current working directory is very likely not as same as the directory of your module file, so using a path relative to your current module file is always a bad choice.

Using absolute path should be the best solution:

import os
package_dir = os.path.dirname(os.path.abspath(__file__))
thefile = os.path.join(package_dir,'test.cvs')

var element =  document.querySelector('selector');
var bodyRect = document.body.getBoundingClientRect(),
    elemRect = element.getBoundingClientRect(),
    offset   = elemRect.top - bodyRect.top;

You could do like this:

SELECT city FROM user WHERE (firstName, lastName) IN (('a', 'b'), ('c', 'd'));

Call WinAPI function (if u are developing win-application)

You reference a Linux distribution, so you need to install the readline development libraries

On Debian based platforms, like Ubuntu, you can run:

sudo apt-get install libreadline-dev 

and that should install the correct headers in the correct places,.

If you use a platform with yum, like SUSE, then the command should be:

yum install readline-devel

This method is deprecated now from now starting with Android Q.

Try This will really help.

                    } else {

                        btnOnOff.setText("Wifi OFF");
                    }
                } else {// if it is Android Q and above go for the newer way    NOTE: You can also use this code for less than android Q also

... except ValueError:
...   print "not found"
... else:

...
not found

find()

>>> if "xxxxABCDyyyy".find("ABCD") != -1:
...   print "found"
...
found

re

1. The point of using CDN is that it is faster, first of all, because it is a distributed network, but secondly, because the static files are being cached by the browsers and chances are high that, for example, the CDN's jquery library that your site uses had already been downloaded by the user's browser, and therefore the file had been cached, and therefore no unnecessary download is taking place. That being said, it is still a good idea to provide a fallback.

   Now, the point of bootstrap's npm package

   is that it provides bootstrap's javascript file as a module. As has been mentioned above, this makes it possible to require it using browserify, which is the most likely use case and, as I understand it, the main reason for bootstrap being published on npm.

2. How to use it

   Imagine the following project structure:

   project
   |-- node_modules
   |-- public
   |   |-- css
   |   |-- img
   |   |-- js
   |   |-- index.html
   |-- package.json
   
   

In your index.html you can reference both css and js files like this:

<link rel="stylesheet" href="../node_modules/bootstrap/dist/css/bootstrap.min.css">
<script src="../node_modules/bootstrap/dist/js/bootstrap.min.js"></script>

Which is the simplest way, and correct for the .css files. But it is much better to include the bootstrap.js file like this somewhere in your public/js/*.js files:

var bootstrap = require('bootstrap');

And you include this code only in those javascript files where you actually need bootstrap.js. Browserify takes care of including this file for you.

Now, the drawback is that you now have your front-end files as node_modules dependencies, and the node_modules folder is usually not checked in with git. I think this is the most controversial part, with many opinions and solutions.

UPDATE March 2017

Almost two years have passed since I wrote this answer and an update is in place.

Now the generally accepted way is to use a bundler like webpack (or another bundler of choice) to bundle all your assets in a build step.

Firstly, it allows you to use commonjs syntax just like browserify, so to include bootstrap js code in your project you do the same:

const bootstrap = require('bootstrap');

As for the css files, webpack has so called "loaders". They allow you write this in your js code:

require('bootstrap/dist/css/bootstrap.css');

and the css files will be "magically" included in your build. They will be dynamically added as <style /> tags when your app runs, but you can configure webpack to export them as a separate css file. You can read more about that in webpack's documentation.

In conclusion.

1. You should "bundle" your app code with a bundler
2. You shouldn't commit neither node_modules nor the dynamically built files to git. You can add a build script to npm which should be used to deploy files on server. Anyway, this can be done in different ways depending on your preferred build process.

It is very straight forward

HTML

<input type="text" placeholder="some text" />
<input type="button" value="button" class="button"/>
<button class="button">Another button</button>

jQuery

$(document).ready(function(){
  $('.button').css( 'cursor', 'pointer' );

  // for old IE browsers
  $('.button').css( 'cursor', 'hand' ); 
});

Do you mean any specific syntax for wildcards? Usually * stands for "one or many" characters and ? stands for one.

The simplest way probably is to translate a wildcard expression into a regular expression, then use that for filtering the results.

easily kick out the problem by just add this line both try and catch block path: node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js

bson = require('bson');  instead

That is all!!!

You can groupby the 'name' and 'month' columns, then call transform which will return data aligned to the original df and apply a lambda where we join the text entries:

In [119]:

df['text'] = df[['name','text','month']].groupby(['name','month'])['text'].transform(lambda x: ','.join(x))
df[['name','text','month']].drop_duplicates()
Out[119]:
    name         text  month
0  name1       hej,du     11
2  name1        aj,oj     12
4  name2     fin,katt     11
6  name2  mycket,lite     12

I sub the original df by passing a list of the columns of interest df[['name','text','month']] here and then call drop_duplicates

EDIT actually I can just call apply and then reset_index:

In [124]:

df.groupby(['name','month'])['text'].apply(lambda x: ','.join(x)).reset_index()

Out[124]:
    name  month         text
0  name1     11       hej,du
1  name1     12        aj,oj
2  name2     11     fin,katt
3  name2     12  mycket,lite

update

the lambda is unnecessary here:

In[38]:
df.groupby(['name','month'])['text'].apply(','.join).reset_index()

Out[38]: 
    name  month         text
0  name1     11           du
1  name1     12        aj,oj
2  name2     11     fin,katt
3  name2     12  mycket,lite

I got the same problem when toggling the accordion. But when I try to put the script block in the header block, it works for my case!!

<head>   
...   
<link rel="stylesheet" href="../assets/css/bootstrap.css" />       
<script src="../assets/js/jquery-1.9.1.min.js" ></script>   
<script src="../assets/js/bootstrap.js" ></script> 
</head>

If you specify CSS attributes for your body element it should apply to anything within <body></body> so long as you don't override them later in the stylesheet.

Similar to tight_layout matplotlib now (as of version 2.2) provides constrained_layout. In contrast to tight_layout, which may be called any time in the code for a single optimized layout, constrained_layout is a property, which may be active and will optimze the layout before every drawing step.

Hence it needs to be activated before or during subplot creation, such as figure(constrained_layout=True) or subplots(constrained_layout=True).

Example:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(4,4, constrained_layout=True)

plt.show()

constrained_layout may as well be set via rcParams

plt.rcParams['figure.constrained_layout.use'] = True

See the what's new entry and the Constrained Layout Guide

If you want it visually formatted to two decimals as a string (for output) use toFixed():

var priceString = someValue.toFixed(2);

The answer by @David has two problems:

1. It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999 instead of "134.20".

2. If your value is an integer or rounds to one tenth, you will not see the additional decimal value:

   var n = 1.099;
   (Math.round( n * 100 )/100 ).toString() //-> "1.1"
   n.toFixed(2)                            //-> "1.10"
   
   var n = 3;
   (Math.round( n * 100 )/100 ).toString() //-> "3"
   n.toFixed(2)                            //-> "3.00"
   

And, as you can see above, using toFixed() is also far easier to type. ;)

I'm blind, and have been programming for about 13 years on Windows, Mac, Linux and DOS, in languages from C/C++, Python, Java, C# and various smaller languages along the way. Though the original question was around configuring the environment, I think it's best answered by looking at how a blind person would use a computer.

Some people use a talking environment, such as T. V. Raman and the Emacspeak environment mentioned in other answers. The more common solution by far is to have a screen reader which runs in the background monitoring OS activity and alerting the user via synthetic speech or a physical braille display (generally showing somewhere from 20 to 80 characters at a time). This then means a blind person can use any accessible application.

So, I personally use Visual Studio 2008 these days, and run it with very few modifications. I turn off certain features like displaying errors as I type since I find this distracting. Prior to joining Microsoft all my development was done in a standard text editor like Notepad, so once again no customisations.

It is possible to configure a screen reader to announce indentation. I personally don't use this, since Visual Studio takes care of this, and C# uses braces. But this would be very important in a language like Python where whitespace matters. Finally, Emacspeak does make use of different voices/pitches to indicate different parts of syntax (keywords, comments, identifiers, etc).

As an alternative you may want to check out BridgeIt at bridgeit.mobi. Open source, it has resolved the browser performance / consistency issue discussed above in that it leverages the standard browser on the device vs. the web-view browser. It also allows you to access the native features without having to worry about app store deployments and/or native containers.

I've used if for simple camera based access and scanner access and it works well for simple apps. Documentation is a bit light. Not sure how it would do on more complex apps.

This alternative approach uses SQL Server's OUTER APPLY clause. This way, it

1. creates the distinct list of games, and
2. fetches and outputs the record with the lowest point number for that game.

The OUTER APPLY clause can be imagined as a LEFT JOIN, but with the advantage that you can use values of the main query as parameters in the subquery (here: game).

SELECT colMinPointID
FROM (
  SELECT game
  FROM table
  GROUP BY game
) As rstOuter
OUTER APPLY (
  SELECT TOP 1 id As colMinPointID
  FROM table As rstInner
  WHERE rstInner.game = rstOuter.game
  ORDER BY points
) AS rstMinPoints

There are two issues here.

Firstly, you can't use the [] syntax like you may be able to in other languages. Square brackets only apply to arrays in Java, and so can only be used with integer indexes.

data.put is correct but that is a statement and so must exist in a method block. Only field declarations can exist at the class level. Here is an example where everything is within the local scope of a method:

public class Data {
     public static void main(String[] args) {
         Map<String, String> data = new HashMap<String, String>();
         data.put("John", "Taxi Driver");
         data.put("Mark", "Professional Killer");
     }
 }

If you want to initialize a map as a static field of a class then you can use Map.of, since Java 9:

public class Data {
    private static final Map<String, String> DATA = Map.of("John", "Taxi Driver");
}

Before Java 9, you can use a static initializer block to accomplish the same thing:

public class Data {
    private static final Map<String, String> DATA = new HashMap<>();

    static {
        DATA.put("John", "Taxi Driver");
    }
}

$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
    $IP
}

Get-content Filename returns an array of strings for each line.

On the first string only, I split it based on ",". Dumping it into $IP_Array.

$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
  if ($IP -eq "2.2.2.2") {
    Write-Host "Found $IP"
  }
}

My understanding of the Android application framework is that this is specifically not permitted. An application is closed automatically when it contains no more current activities. Trying to create a "kill" button is apparently contrary to the intended design of the application system.

To get the sort of effect you want, you could initiate your various activities with startActivityForResult(), and have the exit button send back a result which tells the parent activity to finish(). That activity could then send the same result as part of its onDestroy(), which would cascade back to the main activity and result in no running activities, which should cause the app to close.

The relevel() command is a shorthand method to your question. What it does is reorder the factor so that whatever is the ref level is first. Therefore, reordering your factor levels will also have the same effect but gives you more control. Perhaps you wanted to have levels 3,4,0,1,2. In that case...

bFactor <- factor(b, levels = c(3,4,0,1,2))

I prefer this method because it's easier for me to see in my code not only what the reference was but the position of the other values as well (rather than having to look at the results for that).

NOTE: DO NOT make it an ordered factor. A factor with a specified order and an ordered factor are not the same thing. lm() may start to think you want polynomial contrasts if you do that.

Add vertical-align: middle; to the td element that contains the button

<td style="vertical-align:middle;">  <--add this to center vertically
  <a href="#" class="btn btn-primary">
    <i class="icon-check icon-white"></i>
  </a>
</td>

Of course. That is normal and sane behaviour. Instead of closing and re-opening, you could rewind the file.

boolval() works for complicated tables where declaring variables and adding loops and filters do not work. Example:

$result[$row['name'] . "</td><td>" . (boolval($row['special_case']) ? 'True' : 'False') . "</td><td>" . $row['more_fields'] = $tmp

where $tmp is a key used in order to transpose other data. Here, I wanted the table to display "Yes" for 1 and nothing for 0, so used (boolval($row['special_case']) ? 'Yes' : '').

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

You can just split the string..

public String[] split(String regex)

Note that java.lang.String.split uses delimiter's regular expression value. Basically like this...

String filename = "abc.def.ghi";     // full file name
String[] parts = filename.split("\\."); // String array, each element is text between dots

String beforeFirstDot = parts[0];    // Text before the first dot

Of course, this is split into multiple lines for clairity. It could be written as

String beforeFirstDot = filename.split("\\.")[0];

If you installed rspec as a plugin rather than as a gem, then you won't have the spec executable.

At any rate, All you need to do is run the file using ruby. The rspec code is clever enough to run the tests for you.

eg:

ruby myclass_spec.rb

The right solution is to use grep -v "word" file, with its awk equivalent:

awk '!/word/' file

However, if you happen to have a more complex situation in which you want, say, XXX to appear and YYY not to appear, then awk comes handy instead of piping several greps:

awk '/XXX/ && !/YYY/' file
#    ^^^^^    ^^^^^^
# I want it      |
#            I don't want it

You can even say something more complex. For example: I want those lines containing either XXX or YYY, but not ZZZ:

awk '(/XXX/ || /YYY/) && !/ZZZ/' file

etc.
