I searched for lomob.jar in .m2 repo. Once you double click it -> Search eclipse.exe and select it. After lombok will make the required changes. Explicitly quit eclipse -> it should be fixed by now. If not do a maven Update.

Although all of the answers above are good, I would like to propose a new method instead of using the symbolic link method in public html directory as proposed BEST in the accepted answer. You need to have access to your server virtual host configurations.

It is about configuring virtual host of your web server directly pointing to the repository directory. In Apache you can do it like:

DocumentRoot /var/www/html/website/your-git-repo

Here is an example of a virtual host file:

<VirtualHost *:443>
    ServerName example.com

    DocumentRoot /path/to/your-git-repo
    ...
    ...
    ...
    ...
</VirtualHost>

SELECT set_config('log_statement', 'all', true);

With a corresponding user right may use the query above after connect. This will affect logging until session ends.

If you think you have unique endpoint names and still this error is given then probably you are facing issue. Same was the case with me.

This issue is with flask 0.10 in case you have same version then do following to get rid of this:

sudo pip uninstall flask
sudo pip install flask=0.9

Extension methods are syntactic sugar for making static methods whose first parameter is an instance of type T look as if they were an instance method on T.

As such the benefit is largely lost where you to make 'static extension methods' since they would serve to confuse the reader of the code even more than an extension method (since they appear to be fully qualified but are not actually defined in that class) for no syntactical gain (being able to chain calls in a fluent style within Linq for example).

Since you would have to bring the extensions into scope with a using anyway I would argue that it is simpler and safer to create:

public static class DateTimeUtils
{
    public static DateTime Tomorrow { get { ... } }
}

And then use this in your code via:

WriteLine("{0}", DateTimeUtils.Tomorrow)

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').html(); 
                console.log($variable);
            }
        });
    });

or

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').text(); 
                console.log($variable);
            }
        });
    });

or

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').val(); 
                console.log($variable);
            }
        });
    });

git pull is really equivalent to running git fetch and then git merge. The git fetch updates your so-called "remote-tracking branches" - typically these are ones that look like origin/master, github/experiment, etc. that you see with git branch -r. These are like a cache of the state of branches in the remote repository that are updated when you do git fetch (or a successful git push).

So, suppose you've got a remote called origin that refers to your GitHub repository, you would do:

git fetch origin

... and then do:

git diff master origin/master

... in order to see the difference between your master, and the one on GitHub. If you're happy with those differences, you can merge them in with git merge origin/master, assuming master is your current branch.

Personally, I think that doing git fetch and git merge separately is generally a good idea.

Here, as the Text widget does not have a property that allows us to define a border, we should wrap it with a widget that allows us to define a border. There are several solutions.
But the best solution is the use of BoxDecoration in the Container widget.

Why choose to use BoxDecoration ?
Because BoxDecoration offers more customization like the possibility to define :
First, the border and also define:

• border Color
• border width
• border radius
• shape
• and more ...

An example :

   Container(
     child:Text(' Hello Word '),
     decoration: BoxDecoration(
          color: Colors.yellow,
          border: Border.all(
                color: Colors.red ,
                width: 2.0 ,
              ),
          borderRadius: BorderRadius.circular(15),
            ),
          ),

Output :

New way I've just stumbled upon: css calc():

.calculated-width {
    width: -webkit-calc(100% - 100px);
    width:    -moz-calc(100% - 100px);
    width:         calc(100% - 100px);
}?

Source: css width 100% minus 100px

Your sum

v1 + (incident edges) + v2 + (incident edges) + .... + vn + (incident edges)

can be rewritten as

(v1 + v2 + ... + vn) + [(incident_edges v1) + (incident_edges v2) + ... + (incident_edges vn)]

and the first group is O(N) while the other is O(E).

Ok, well, first of all, let me check if I am on the same page as you:

• You installed python
• You did brew install mysql
• You did export PATH=$PATH:/usr/local/mysql/bin
• And finally, you did pip install MySQL-Python (or pip3 install mysqlclient if using python 3)

If you did all those steps in the same order, and you still got an error, read on to the end, if, however, you did not follow these exact steps try, following them from the very beginning.

So, you followed the steps, and you're still geting an error, well, there are a few things you could try:

1. Try running which mysql_config from bash. It probably won't be found. That's why the build isn't finding it either. Try running locate mysql_config and see if anything comes back. The path to this binary needs to be either in your shell's $PATH environment variable, or it needs to be explicitly in the setup.py file for the module assuming it's looking in some specific place for that file.

2. Instead of using MySQL-Python, try using 'mysql-connector-python', it can be installed using pip install mysql-connector-python. More information on this can be found here and here.

3. Manually find the location of 'mysql/bin', 'mysql_config', and 'MySQL-Python', and add all these to the $PATH environment variable.

4. If all above steps fail, then you could try installing 'mysql' using MacPorts, in which case the file 'mysql_config' would actually be called 'mysql_config5', and in this case, you would have to do this after installing: export PATH=$PATH:/opt/local/lib/mysql5/bin. You can find more details here.

Note1: I've seen some people saying that installing python-dev and libmysqlclient-dev also helped, however I do not know if these packages are available on Mac OS.

Note2: Also, make sure to try running the commands as root.

I got my answers from (besides my brain) these places (maybe you could have a look at them, to see if it would help): 1, 2, 3, 4.

I hoped I helped, and would be happy to know if any of this worked, or not. Good luck.

In spring boot I get same exception by using CrudRepository because I forgot to set generic types. I want to write it here in case it helps someone.

errorneous definition:

public interface OctopusPropertiesRepository extends CrudRepository

error:

Caused by: java.lang.IllegalArgumentException: Not a managed type: class java.lang.Object

successfull definition:

public interface OctopusPropertiesRepository extends CrudRepository<OctopusProperties,Long>{

The ceil and floor methods will help you determine if the number is a whole number.

However if you want to determine if the number can be represented by an int value.

if(value == (int) value)

or a long (64-bit integer)

if(value == (long) value)

or can be safely represented by a float without a loss of precision

if(value == (float) value)

BTW: don't use a 32-bit float unless you have to. In 99% of cases a 64-bit double is a better choice.

Add the NUnit test adapter NuGet package to your test projects

• 2.* (https://www.nuget.org/packages/NUnitTestAdapter/)
• 3.* (https://www.nuget.org/packages/NUnit3TestAdapter/)

Or install the Test Adapter Visual Studio extension. There is one for

• 2.* (https://marketplace.visualstudio.com/items?itemName=NUnitDevelopers.NUnitTestAdapter)
• 3.* (https://marketplace.visualstudio.com/items?itemName=NUnitDevelopers.NUnit3TestAdapter).

I prefer the NuGet package, because it will be in sync with the NUnit version used by your project and will thus automatically match the version used in any build server.

Using the -n /usr/local/bin flag does work, BUT I had to come back to this page every time I wanted to update a package again. So I figured out a permanent fix for this.

For those interested in fixing this permanently:

Create a ~/.gemrc file

vim .gemrc

With the following content:

:gemdir:
   - ~/.gem/ruby
install: -n /usr/local/bin

Now you can run your command normally without the -n flag.

Enjoy!

$('.update-cart').click(function(e) {
    updateCartWidget();
    e.stopPropagation();
    e.preventDefault();
});

$('.update-cart').click(function() {
    updateCartWidget();
    return false;
});

The following methods achieve the exact same thing.

Try this

const returnedTarget = Object.assign(target, source);

and pass empty array to target

in case complex objects this way works for me

$.extend(true, [], originalArray) in case of array

$.extend(true, {}, originalObject) in case of object

I found a way to do it that doesn't depend on non-standard libraries!

Found this in Tkinter

self.winfo_pointerxy()

In my particular instance, I was connected to a VPN and that was blocking the localhost connection to MongoDB somehow. It worked when I disconnected my VPN. It's a special case, but good to know nonetheless. So anything impeding your network connectivity, Get that fixed.

I think you're missing your routes, you need to define at least one route for example '/' to index.

e.g.

app.get('/', function (req, res) {
  res.render('index', {});
});

Simple: When you use curl it encodes the string to utf-8 you just need to decode them..

Description

string utf8_decode ( string $data )

This function decodes data , assumed to be UTF-8 encoded, to ISO-8859-1.

You could use FileAPI, but it's pretty much unsupported.

Use grep -vc to ignore grep in the ps output and count the lines simultaneously.

if [[ $(ps aux | grep process | grep -vc grep)  > 0 ]] ; then echo 1; else echo 0 ; fi

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

When we use crontab or the deprecated /etc/rc.local file, we need a delay (e.g. sleep 10, depending on the machine) to make sure that system services are available. Usually, systemd (or upstart) is used to manage which services start when the system boots. You can try use the similar configuration for this:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Or, if you want run without the -d flag:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitIntervalSec=60
StartLimitBurst=3

[Install]
WantedBy=multi-user.target

Change the WorkingDirectory parameter with your dockerized project path. And enable the service to start automatically:

systemctl enable docker-compose-app

http://localhost/phpmyadmin

Username: root

Many frameworks like Laravel , Django ,... run local web server that work on another port except 80.For example port 8000 is the most commen port that these local web servers use.

So when you run web servers that frameworks build them and type localhost:8000 it works well.But web server that xampp(apache) runs it has another port.In default it has 80 that it does not need to type it in url.And if you change port you should mention it in url.

**In brief:**web server in framework is different from web server in xampp . Check the port of each server and mention it in url when you use them.

UPDATE some_table 
   SET this_column=x, that_column=y 
   WHERE something LIKE 'them'

In this two queries, you are using JOIN to query all employees that have at least one department associated.

But, the difference is: in the first query you are returning only the Employes for the Hibernate. In the second query, you are returning the Employes and all Departments associated.

So, if you use the second query, you will not need to do a new query to hit the database again to see the Departments of each Employee.

You can use the second query when you are sure that you will need the Department of each Employee. If you not need the Department, use the first query.

I recomend read this link if you need to apply some WHERE condition (what you probably will need): How to properly express JPQL "join fetch" with "where" clause as JPA 2 CriteriaQuery?

Update

If you don't use fetch and the Departments continue to be returned, is because your mapping between Employee and Department (a @OneToMany) are setted with FetchType.EAGER. In this case, any HQL (with fetch or not) query with FROM Employee will bring all Departments. Remember that all mapping *ToOne (@ManyToOne and @OneToOne) are EAGER by default.

Like any project setting, the buildevents can be configured per Configuration. Just select the configuration you want to change in the dropdown of the Property Pages dialog and edit the post build step.

First off, you'll want to go through Oracle's tutorial to learn how to do basic I/O in Java.

After that, you will want to look at the tutorial on how to use a file chooser.

1. first download below software https://www.microsoft.com/en-us/download/details.aspx?id=30679 - need to install

https://www.microsoft.com/en-us/download/details.aspx?id=20098 - when you run this software . it will extract dll file. and paste two dll file(php_pdo_sqlsrv_55_ts.dll,extension=php_sqlsrv_55_ts.dll) this location C:\wamp\bin\php\php5.6.40\ext\ (pls make sure your current version)

2)edit php.ini file add below line extension=php_pdo_sqlsrv_55_ts.dll extension=php_sqlsrv_55_ts.dll

Please refer screenshort add dll in your php.ini file

If you're using Selenium with Firefox you should be able to use EXSLT extensions, and regexp:test()

Does this work for you?

String expr = "//*[regexp:test(@id, 'sometext[0-9]+_text')]";
driver.findElement(By.xpath(expr));

To create a read-only user, you have to setup a different user than the one owning the tables you want to access.

If you just create the user and grant SELECT permission to the read-only user, you'll need to prepend the schema name to each table name. To avoid this, you have basically two options:

1. Set the current schema in your session:

ALTER SESSION SET CURRENT_SCHEMA=XYZ

2. Create synonyms for all tables:

CREATE SYNONYM READER_USER.TABLE1 FOR XYZ.TABLE1

So if you haven't been told the name of the owner schema, you basically have three options. The last one should always work:

1. Query the current schema setting:

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL

2. List your synonyms:

SELECT * FROM ALL_SYNONYMS WHERE OWNER = USER

3. Investigate all tables (with the exception of the some well-known standard schemas):

SELECT * FROM ALL_TABLES WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'CTXSYS', 'MDSYS');

As mentioned in Jonathan's answer, FETCH_HEAD corresponds to the file .git/FETCH_HEAD. Typically, the file will look like this:

71f026561ddb57063681109aadd0de5bac26ada9                        branch 'some-branch' of <remote URL>
669980e32769626587c5f3c45334fb81e5f44c34        not-for-merge   branch 'some-other-branch' of <remote URL>
b858c89278ab1469c71340eef8cf38cc4ef03fed        not-for-merge   branch 'yet-some-other-branch' of <remote URL>

Note how all branches but one are marked not-for-merge. The odd one out is the branch that was checked out before the fetch. In summary: FETCH_HEAD essentially corresponds to the remote version of the branch that's currently checked out.

This is actually very simple, and that worked for me :)

        if (id == "DK")
        {
            string longurl = "selectServer.aspx?country=";
            var uriBuilder = new UriBuilder(longurl);
            var query = HttpUtility.ParseQueryString(uriBuilder.Query);
            query["country"] = "DK";

            uriBuilder.Query = query.ToString();
            longurl = uriBuilder.ToString();
        } 

I had the same problem. So here is the real answer: Mount the system under /proc. Here is my command:

mount -o rw,remount /proc /system

It works, and in fact is the only way I can overcome the Read-only System problem.

On MAC OS X Leopard and higher

cd /etc/paths.d

There may be a text file in the above directory that contains the path you are trying to remove.

vim textfile //check and see what is in it when you are done looking type :q 
//:q just quits, no saves

If its the one you want to remove do this

rm textfile //remove it, delete it

Here is a link to a site that has more info on it, even though it illustrates 'adding' the path. However, you may gain some insight.

If you are accessing your repositories over the SSH protocol, you will receive a warning message each time your client connects to a new IP address for github.com. As long as the IP address from the warning is in the range of IP addresses , you shouldn't be concerned. Specifically, the new addresses that are being added this time are in the range from 192.30.252.0 to 192.30.255.255. The warning message looks like this:

Warning: Permanently added the RSA host key for IP address '$IP' to the list of

LinqPad is a quick way to test out some C# code, and its free.

@WilliamJockusch, if I understood correctly your concern, it's not possible (from a mathematical point of view) to always identify an infinite recursion as it would mean to solve the Halting problem. To solve it you'd need a Super-recursive algorithm (like Trial-and-error predicates for example) or a machine that can hypercompute (an example is explained in the following section - available as preview - of this book).

From a practical point of view, you'd have to know:

• How much stack memory you have left at the given time
• How much stack memory your recursive method will need at the given time for the specific output.

Keep in mind that, with the current machines, this data is extremely mutable due to multitasking and I haven't heard of a software that does the task.

Let me know if something is unclear.

INSERT INTO ... ON DUPLICATE KEY UPDATE will only work for MYSQL, not for SQL Server.

for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE

Like this:

declare @Source table
(
name varchar(30),
age decimal(23,0)
)

insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);


MERGE beautiful  AS Tg
using  @source as Sc
on tg.namet=sc.name 

when matched then update 
set tg.age=sc.age

when not matched then 
insert (name, age) VALUES
(SC.name, sc.age);

drop procedure if exists doWhile;
DELIMITER //  
CREATE PROCEDURE doWhile()   
BEGIN
DECLARE i INT DEFAULT 2376921001; 
WHILE (i <= 237692200) DO
    INSERT INTO `mytable` (code, active, total) values (i, 1, 1);
    SET i = i+1;
END WHILE;
END;
//  

CALL doWhile(); 

What you could also have a look at is the exposed method Application->loadEnvironmentFrom($file)

I needed one application to run on multiple subdomains. So in bootstrap/app.php I added something like:

$envFile = '.env';
// change $envFile conditionally here
$app->loadEnvironmentFrom($envFile);

I found the perfect way to Ignore files in TFS like SVN does.
First of all, select the file that you want to ignore (e.g. the Web.config).
Now go to the menu tab and select:

File Source control > Advanced > Exclude web.config from source control

... and boom; your file is permanently excluded from source control.

Also, name it divrat.m, not divrat.M. This shouldn't matter on most OSes, but who knows...

You can also test whether matlab can find a function by using the which command, i.e.

which divrat

First, revert the working copy to 1943.

> svn merge -c -1943 .

Second, check what is about to be commited.

> svn status

Third, commit version 1945.

> svn commit -m "Fix bad commit."

Fourth, look at the new log.

> svn log -l 4

As per my understanding data structure is any data residing in memory of any electronic system that can be efficiently managed. Many times it is a game of memory or faster accessibility of data. In terms of memory again, there are tradeoffs done with the management of data based on cost to the company of that end product. Efficiently managed tells us how best the data can be accessed based on the primary requirement of the end product. This is a very high level explanation but data structures is a vast subjects. Most of the interviewers dive into data structures that they can afford to discuss in the interviews depending on the time they have, which are linked lists and related subjects.

Now, these data types can be divided into primitive, abstract, composite, based on the way they are logically constructed and accessed.

• primitive data structures are basic building blocks for all data structures, they have a continuous memory for them: boolean, char, int, float, double, string.
• composite data structures are data structures that are composed of more than one primitive data types.class, structure, union, array/record.
• abstract datatypes are composite datatypes that have way to access them efficiently which is called as an algorithm. Depending on the way the data is accessed data structures are divided into linear and non linear datatypes. Linked lists, stacks, queues, etc are linear data types. heaps, binary trees and hash tables etc are non linear data types.

I hope this helps you dive in.

Here's a very simple solution without too much code using a very simple map of diacritics that includes some or all that map to ascii equivalents containing more than one character, i.e. Æ => AE, ? => ffi, etc... Also included some very basic functional tests

Can't be done natively with VBA. VBA is built in a single-threaded apartment. The only way to get multiple threads is to build a DLL in something other than VBA that has a COM interface and call it from VBA.

INFO: Descriptions and Workings of OLE Threading Models

You can check Long object for null value with longValue == null , you can use longValue == 0L for long (primitive), because default value of long is 0L, but it's result will be true if longValue is zero too

in python the operators should be in quotes: db.ProductData.update({'fromAddress':'http://localhost:7000/'}, {"$set": {'fromAddress': 'http://localhost:5000/'}},{"multi": True})

Start with:

find . -name '*.log.*.zip' -a -mtime +1

You may not need a regex, try:

 find . -name '*.log.*-*-*.zip' -a -mtime +1

You will want the +1 in order to match 1, 2, 3 ...

Yes, it does deserialize to List<>. No need to keep it in an array and wrap/encapsulate it in a list.

public class UserHolder
{
    private List<User> users = null;

    public UserHolder()
    {
    }

    [XmlElement("user")]
    public List<User> Users
    {
        get { return users; }
        set { users = value; }
    }
}

Deserializing code,

XmlSerializer xs = new XmlSerializer(typeof(UserHolder));
UserHolder uh = (UserHolder)xs.Deserialize(new StringReader(str));

When you use Vector *one you are merely creating a pointer to the structure but there is no memory allocated to it.

Simply use one = (Vector *)malloc(sizeof(Vector)); to declare memory and instantiate it.

I do this all the time. If you're using ADO, you're not really using Access, but Jet, the underlying database. That means anybody with Excel can use the app - Access not required. Oh I should mention, the place I work bought a bunch of Office Small Business licenses - no Access. Prior to working here, I would have assumed that anyone who had Excel would also have Access. Not so.

I create one class for every table in Access. I very rarely run queries through ADO, instead I keep that logic in the class modules. I read in with a SELECT statement and write out with and UPDATE or INSERT using the Execute method of the ADODB.Connection object.

See http://www.dailydoseofexcel.com/archives/2008/12/21/vba-framework-ii/

if you want to see how I set up my code.

To answer your questions: It will be a small learning curve for you if you already know Excel VBA, but there will be some learning to do; you will pay a performance penalty over doing it all in Access, but it's not that bad and only you can decide if it's worth it; and you can have multiple people accessing the database.

I used the plugin Smooth Scroll, at http://plugins.jquery.com/smooth-scroll/. With this plugin all you need to include is a link to jQuery and to the plugin code:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="javascript/smoothscroll.js"></script>

(the links need to have the class smoothScroll to work).

Another feature of Smooth Scroll is that the ancor name is not displayed in the URL!

event.stopPropagation() allows other handlers on the same element to be executed, while event.stopImmediatePropagation() prevents every event from running. For example, see below jQuery code block.

$("p").click(function(event)
{ event.stopImmediatePropagation();
});
$("p").click(function(event)
{ // This function won't be executed 
$(this).css("color", "#fff7e3");
});

If event.stopPropagation was used in previous example, then the next click event on p element which changes the css will fire, but in case event.stopImmediatePropagation(), the next p click event will not fire.

For me I usually send back an HttpResponseException and set the status code accordingly depending on the exception thrown and if the exception is fatal or not will determine whether I send back the HttpResponseException immediately.

At the end of the day it's an API sending back responses and not views, so I think it's fine to send back a message with the exception and status code to the consumer. I currently haven't needed to accumulate errors and send them back as most exceptions are usually due to incorrect parameters or calls etc.

An example in my app is that sometimes the client will ask for data, but there isn't any data available so I throw a custom NoDataAvailableException and let it bubble to the Web API app, where then in my custom filter which captures it sending back a relevant message along with the correct status code.

I am not 100% sure on what's the best practice for this, but this is working for me currently so that's what I'm doing.

Update:

Since I answered this question a few blog posts have been written on the topic:

https://weblogs.asp.net/fredriknormen/asp-net-web-api-exception-handling

(this one has some new features in the nightly builds) https://docs.microsoft.com/archive/blogs/youssefm/error-handling-in-asp-net-webapi

Update 2

Update to our error handling process, we have two cases:

1. For general errors like not found, or invalid parameters being passed to an action we return a HttpResponseException to stop processing immediately. Additionally for model errors in our actions we will hand the model state dictionary to the Request.CreateErrorResponse extension and wrap it in a HttpResponseException. Adding the model state dictionary results in a list of the model errors sent in the response body.

2. For errors that occur in higher layers, server errors, we let the exception bubble to the Web API app, here we have a global exception filter which looks at the exception, logs it with ELMAH and tries to make sense of it setting the correct HTTP status code and a relevant friendly error message as the body again in a HttpResponseException. For exceptions that we aren't expecting the client will receive the default 500 internal server error, but a generic message due to security reasons.

Update 3

Recently, after picking up Web API 2, for sending back general errors we now use the IHttpActionResult interface, specifically the built in classes for in the System.Web.Http.Results namespace such as NotFound, BadRequest when they fit, if they don't we extend them, for example a NotFound result with a response message:

public class NotFoundWithMessageResult : IHttpActionResult
{
    private string message;

    public NotFoundWithMessageResult(string message)
    {
        this.message = message;
    }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var response = new HttpResponseMessage(HttpStatusCode.NotFound);
        response.Content = new StringContent(message);
        return Task.FromResult(response);
    }
}

For strings of non-numbers, try: except: is actually slower than regular expressions. For strings of valid numbers, regex is slower. So, the appropriate method depends on your input.

If you find that you are in a performance bind, you can use a new third-party module called fastnumbers that provides a function called isfloat. Full disclosure, I am the author. I have included its results in the timings below.

fastnumbers with integer strings 0.179651021957 seconds
fastnumbers with float strings 0.20222902298 seconds

As you can see

• try: except: was fast for numeric input but very slow for an invalid input
• regex is very efficient when the input is invalid
• fastnumbers wins in both cases

If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:

sudo nano .bashrc

chmod 777 .bashrc 

it is worthless

You can try this, see if it works for you.

Rather than choosing date from date picker, you can enable the date box using javascript & enter the required date, this would avoid excessive time required to traverse through all date elements till you reach one you require to select.

Code for from date

((JavascriptExecutor)driver).executeScript ("document.getElementById('fromDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement fromDateBox= driver.findElement(By.id("fromDate"));
fromDateBox.clear();
fromDateBox.sendKeys("8-Dec-2014"); //Enter date in required format

Code for to date

((JavascriptExecutor)driver).executeScript ("document.getElementById('toDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement toDateBox= driver.findElement(By.id("toDate"));
toDateBox.clear();
toDateBox.sendKeys("15-Dec-2014"); //Enter date in required format

I had exactly this problem a couple of months ago while working on a WYSIWYG email editor for my company. Outlook only supports background images if they're applied to the <body> tag - any other element and it'll fail.

In the end, the only workaround I found was to use <div> element for text input, then during the content submission process I fired an AJAX request with the <div>'s content to a PHP script which wrote the text onto a blank version of our header image, saved the file and returned its (uniquely generated) name. I then used Javascript to remove the <div> and add an <img> tag using the returned filename in the src attribute.

You can get all the info/methodology from the imagecreatefrompng() page on the PHP Docs site.

when you upload your files to the server be careful ,some tomes your images will not appear on the web page and a crashed icon will appear that means your file path is not properly arranged or coded when you have the the following file structure the code should be like this File structure: ->web(main folder) ->images(subfolder)->logo.png(image in the sub folder)the code for the above is below follow this standard

 <img src="../images/logo.jpg" alt="image1" width="50px" height="50px">

if you uploaded your files to the web server by neglecting the file structure with out creating the folder web if you directly upload the files then your images will be broken you can't see images,then change the code as following

 <img src="images/logo.jpg" alt="image1" width="50px" height="50px">

Might wanna check this, got everything you need for your app icons

http://developer.android.com/guide/practices/ui_guidelines/icon_design.html

update

I think by default it uses your launcher icon... Your best bet is to create a separate image... Designed for the action bar and using that. For that check: http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems

C lets you use the subscript operator [] on arrays and on pointers. When you use this operator on a pointer, the resultant type is the type to which the pointer points to. For example, if you apply [] to int*, the result would be an int.

That is precisely what's going on: you are passing int*, which corresponds to a vector of integers. Using subscript on it once makes it int, so you cannot apply the second subscript to it.

It appears from your code that arr should be a 2-D array. If it is implemented as a "jagged" array (i.e. an array of pointers) then the parameter type should be int **.

Moreover, it appears that you are trying to return a local array. In order to do that legally, you need to allocate the array dynamically, and return a pointer. However, a better approach would be declaring a special struct for your 4x4 matrix, and using it to wrap your fixed-size array, like this:

// This type wraps your 4x4 matrix
typedef struct {
    int arr[4][4];
} FourByFour;
// Now rotate(m) can use FourByFour as a type
FourByFour rotate(FourByFour m) {
    FourByFour D;
    for(int i = 0; i < 4; i ++ ){
        for(int n = 0; n < 4; n++){
            D.arr[i][n] = m.arr[n][3 - i];
        }
    }
    return D;
}
// Here is a demo of your rotate(m) in action:
int main(void) {
    FourByFour S = {.arr = {
        { 1, 4, 10, 3 },
        { 0, 6, 3, 8 },
        { 7, 10 ,8, 5 },
        { 9, 5, 11, 2}
    } };
    FourByFour r = rotate(S);
    for(int i=0; i < 4; i ++ ){
        for(int n=0; n < 4; n++){
            printf("%d ", r.arr[i][n]);
        }
        printf("\n");
    }
    return 0;
}

This prints the following:

3 8 5 2 
10 3 8 11 
4 6 10 5 
1 0 7 9 

My freely available memory profiler MemPro allows you to compare 2 snapshots and gives stack traces for all of the allocations.

This code works even faster (two 1.5 faster than my previous version):

    public List<String> GetUserGroups(WindowsIdentity identity)
    {
        List<String> groups = new List<String>();

        String userName = identity.Name;
        int pos = userName.IndexOf(@"\");
        if (pos > 0) userName = userName.Substring(pos + 1);

        PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
        UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName); // NGeodakov

        DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
        DirectorySearcher search = new DirectorySearcher(de);
        search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
        search.PropertiesToLoad.Add("cn");
        search.PropertiesToLoad.Add("samaccountname");
        search.PropertiesToLoad.Add("memberOf");

        SearchResultCollection results = search.FindAll();
        foreach (SearchResult sr in results)
        {
            GetUserGroupsRecursive(groups, sr, de);
        }

        return groups;
    }

    public void GetUserGroupsRecursive(List<String> groups, SearchResult sr, DirectoryEntry de)
    {
        if (sr == null) return;

        String group = (String)sr.Properties["cn"][0];
        if (String.IsNullOrEmpty(group))
        {
            group = (String)sr.Properties["samaccountname"][0];
        }
        if (!groups.Contains(group))
        {
            groups.Add(group);
        }

        DirectorySearcher search;
        SearchResult sr1;
        String name;
        int equalsIndex, commaIndex;
        foreach (String dn in sr.Properties["memberof"])
        {
            equalsIndex = dn.IndexOf("=", 1);
            if (equalsIndex > 0)
            {
                commaIndex = dn.IndexOf(",", equalsIndex + 1);
                name = dn.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);

                search = new DirectorySearcher(de);
                search.Filter = "(&(objectClass=group)(|(cn=" + name + ")(samaccountname=" + name + ")))";
                search.PropertiesToLoad.Add("cn");
                search.PropertiesToLoad.Add("samaccountname");
                search.PropertiesToLoad.Add("memberOf");
                sr1 = search.FindOne();
                GetUserGroupsRecursive(groups, sr1, de);
            }
        }
    }

I found a more complete listing at user agent string. BTW, this site has more than just iOS user agent strings. Also, the home page will "break down" the user agent string of your current browser for you.

You can use nsolve of sympy, meaning numerical solver.

Example snippet:

from sympy import *

L = 4.11 * 10 ** 5
nu = 1
rho = 0.8175
mu = 2.88 * 10 ** -6
dP = 20000
eps = 4.6 * 10 ** -5

Re, D, f = symbols('Re, D, f')

nsolve((Eq(Re, rho * nu * D / mu),
       Eq(dP, f * L / D * rho * nu ** 2 / 2),
       Eq(1 / sqrt(f), -1.8 * log ( (eps / D / 3.) ** 1.11 + 6.9 / Re))),
      (Re, D, f), (1123, -1231, -1000))

where (1123, -1231, -1000) is the initial vector to find the root. And it gives out:

The imaginary part are very small, both at 10^(-20), so we can consider them zero, which means the roots are all real. Re ~ 13602.938, D ~ 0.047922 and f~0.0057.

with git 1.7, there's a really easy way using git rebase:

stage your files:

git add $files

create a new commit and re-use commit message of your "broken" commit

git commit -c master~4

prepend fixup! in the subject line (or squash! if you want to edit commit (message)):

fixup! Factored out some common XPath Operations

use git rebase -i --autosquash to fixup your commit

dict.copy() is a shallow copy function for dictionary
id is built-in function that gives you the address of variable

First you need to understand "why is this particular problem is happening?"

In [1]: my_dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}

In [2]: my_copy = my_dict.copy()

In [3]: id(my_dict)
Out[3]: 140190444167808

In [4]: id(my_copy)
Out[4]: 140190444170328

In [5]: id(my_copy['a'])
Out[5]: 140190444024104

In [6]: id(my_dict['a'])
Out[6]: 140190444024104

The address of the list present in both the dicts for key 'a' is pointing to same location.
Therefore when you change value of the list in my_dict, the list in my_copy changes as well.

Solution for data structure mentioned in the question:

In [7]: my_copy = {key: value[:] for key, value in my_dict.items()}

In [8]: id(my_copy['a'])
Out[8]: 140190444024176

Or you can use deepcopy as mentioned above.

Having the following XML:

<node>Text1<subnode/>text2</node> 

How do I select either the first or the second text node via XPath?

Use:

/node/text()

This selects all text-node children of the top element (named "node") of the XML document.

/node/text()[1]

This selects the first text-node child of the top element (named "node") of the XML document.

/node/text()[2]

This selects the second text-node child of the top element (named "node") of the XML document.

/node/text()[someInteger]

This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:

/node/text()[position() = someInteger]

import numpy as np, cv2

img1 = cv2.imread(fn1, 0)
img2 = cv2.imread(fn2, 0)
h1, w1 = img1.shape[:2]
h2, w2 = img2.shape[:2]
vis = np.zeros((max(h1, h2), w1+w2), np.uint8)
vis[:h1, :w1] = img1
vis[:h2, w1:w1+w2] = img2
vis = cv2.cvtColor(vis, cv2.COLOR_GRAY2BGR)

cv2.imshow("test", vis)
cv2.waitKey()

or if you prefer legacy way:

import numpy as np, cv

img1 = cv.LoadImage(fn1, 0)
img2 = cv.LoadImage(fn2, 0)

h1, w1 = img1.height,img1.width
h2, w2 = img2.height,img2.width
vis = np.zeros((max(h1, h2), w1+w2), np.uint8)
vis[:h1, :w1] = cv.GetMat(img1)
vis[:h2, w1:w1+w2] = cv.GetMat(img2)
vis2 = cv.CreateMat(vis.shape[0], vis.shape[1], cv.CV_8UC3)
cv.CvtColor(cv.fromarray(vis), vis2, cv.CV_GRAY2BGR)

cv.ShowImage("test", vis2)
cv.WaitKey()

Here's how I would solve it:

1. Just Save your CSV File as a XLS Sheet in excel(By Doing so, you wouldn't have to worry about delimitiers. Excel's spreadsheet format will be read as a table and imported directly into a SQL Table)

2. Import the File Using SSIS

3. Write a Custom Script in the import manager to omit/modify the data you're looking for.(Or run a master script to scrutinize the data you're looking to remove)

Good Luck.

IMHO, fs.readFile() should be avoided because it loads ALL the file in memory and it won't call the callback until all the file has been read.

The easiest way to read a text file is to read it line by line. I recommend a BufferedReader:

new BufferedReader ("file", { encoding: "utf8" })
    .on ("error", function (error){
        console.log ("error: " + error);
    })
    .on ("line", function (line){
        console.log ("line: " + line);
    })
    .on ("end", function (){
        console.log ("EOF");
    })
    .read ();

For complex data structures like .properties or json files you need to use a parser (internally it should also use a buffered reader).

Why not store the function itself? myvar = mypackage.mymodule.myfunction is much cleaner.

One caveat, though. Note that np.array(None).size returns 1! This is because a.size is equivalent to np.prod(a.shape), np.array(None).shape is (), and an empty product is 1.

>>> import numpy as np
>>> np.array(None).size
1
>>> np.array(None).shape
()
>>> np.prod(())
1.0

Therefore, I use the following to test if a numpy array has elements:

>>> def elements(array):
    ...     return array.ndim and array.size

>>> elements(np.array(None))
0
>>> elements(np.array([]))
0
>>> elements(np.zeros((2,3,4)))
24

If you're using oh-my-zsh

Type omz update in the terminal

Note: upgrade_oh_my_zsh is deprecated

You should use urllib.reuqest, not urllib3.

import urllib.request   # not urllib - important!
urllib.request.urlopen('https://...')

Yes there is:

https://www.youtube.com/embed/kObNpTFPV5c?vq=hd1440
https://www.youtube.com/embed/kObNpTFPV5c?vq=hd1080
etc...

Options are:

Code for 1440: vq=hd1440
Code for 1080: vq=hd1080
Code for 720: vq=hd720
Code for 480p: vq=large
Code for 360p: vq=medium
Code for 240p: vq=small

UPDATE
As of 10 of April 2018, this code still works.
Some users reported "not working", if it doesn't work for you, please read below:

From what I've learned, the problem is related with network speed and or screen size.
When YT player starts, it collects the network speed, screen and player sizes, among other information, if the connection is slow or the screen/player size smaller than the quality requested(vq=), a lower quality video is displayed despite the option selected on vq=.

Also make sure you read the comments below.

you can also use a namedQuery named findAll for all your entities and call it in your generic FindAll with

entityManager.createNamedQuery(persistentClass.getSimpleName()+"findAll").getResultList();

On CentOS/RHEL:

yum install cronie

This may be possible by using the refs attribute.

In the example of wanting to to reach a <div> what you would want to do is use is <div ref="myExample">. Then you would be able to get that DOM node by using React.findDOMNode(this.refs.myExample).

From there getting the correct DOM node of each child may be as simple as mapping over this.refs.myExample.children(I haven't tested that yet) but you'll at least be able to grab any specific mounted child node by using the ref attribute.

Here's the official react documentation on refs for more info.

It solved throung second parameter in Model load:

$this->load->model('user','User');

first parameter is the model's filename, and second it defining the name of model to be used in the controller:

function alluser() 
{
$this->load->model('User');
$result = $this->User->showusers();
}

Syntax

To create user in MySQL/MariaDB 5.7.6 and higher, use CREATE USER syntax:

CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'new_password';

then to grant all access to the database (e.g. my_db), use GRANT Syntax, e.g.

GRANT ALL ON my_db.* TO 'new_user'@'localhost';

^{Where ALL (priv_type) can be replaced with specific privilege such as SELECT, INSERT, UPDATE, ALTER, etc.}

Then to reload newly assigned permissions run:

FLUSH PRIVILEGES;

Executing

To run above commands, you need to run mysql command and type them into prompt, then logout by quit command or Ctrl-D.

To run from shell, use -e parameter (replace SELECT 1 with one of above commands):

$ mysql -e "SELECT 1"

or print statement from the standard input:

$ echo "FOO STATEMENT" | mysql

If you've got Access denied with above, specify -u (for user) and -p (for password) parameters, or for long-term access set your credentials in ~/.my.cnf, e.g.

[client]
user=root
password=root

Shell integration

For people not familiar with MySQL syntax, here are handy shell functions which are easy to remember and use (to use them, you need to load the shell functions included further down).

Here is example:

$ mysql-create-user admin mypass
| CREATE USER 'admin'@'localhost' IDENTIFIED BY 'mypass'

$ mysql-create-db foo
| CREATE DATABASE IF NOT EXISTS foo

$ mysql-grant-db admin foo
| GRANT ALL ON foo.* TO 'admin'@'localhost'
| FLUSH PRIVILEGES

$ mysql-show-grants admin
| SHOW GRANTS FOR 'admin'@'localhost'
| Grants for admin@localhost                                                                                   
| GRANT USAGE ON *.* TO 'admin'@'localhost' IDENTIFIED BY PASSWORD '*6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4' |
| GRANT ALL PRIVILEGES ON `foo`.* TO 'admin'@'localhost'

$ mysql-drop-user admin
| DROP USER 'admin'@'localhost'

$ mysql-drop-db foo
| DROP DATABASE IF EXISTS foo

To use above commands, you need to copy&paste the following functions into your rc file (e.g. .bash_profile) and reload your shell or source the file. In this case just type source .bash_profile:

# Create user in MySQL/MariaDB.
mysql-create-user() {
  [ -z "$2" ] && { echo "Usage: mysql-create-user (user) (password)"; return; }
  mysql -ve "CREATE USER '$1'@'localhost' IDENTIFIED BY '$2'"
}

# Delete user from MySQL/MariaDB
mysql-drop-user() {
  [ -z "$1" ] && { echo "Usage: mysql-drop-user (user)"; return; }
  mysql -ve "DROP USER '$1'@'localhost';"
}

# Create new database in MySQL/MariaDB.
mysql-create-db() {
  [ -z "$1" ] && { echo "Usage: mysql-create-db (db_name)"; return; }
  mysql -ve "CREATE DATABASE IF NOT EXISTS $1"
}

# Drop database in MySQL/MariaDB.
mysql-drop-db() {
  [ -z "$1" ] && { echo "Usage: mysql-drop-db (db_name)"; return; }
  mysql -ve "DROP DATABASE IF EXISTS $1"
}

# Grant all permissions for user for given database.
mysql-grant-db() {
  [ -z "$2" ] && { echo "Usage: mysql-grand-db (user) (database)"; return; }
  mysql -ve "GRANT ALL ON $2.* TO '$1'@'localhost'"
  mysql -ve "FLUSH PRIVILEGES"
}

# Show current user permissions.
mysql-show-grants() {
  [ -z "$1" ] && { echo "Usage: mysql-show-grants (user)"; return; }
  mysql -ve "SHOW GRANTS FOR '$1'@'localhost'"
}

Note: If you prefer to not leave trace (such as passwords) in your Bash history, check: How to prevent commands to show up in bash history?

Even though, the best approach for this situation is set custom CSS styles - an alternative could be:

• Use Width property and set the percentaje as you see more suitable for your purposes.

In my desired scenario, I need set (2) radiobuttons/items as follows:

Example:

<asp:RadioButtonList ID="rbtnLstOptionsGenerateCertif" runat="server" 
    BackColor="Transparent" BorderColor="Transparent" RepeatDirection="Horizontal" 
    EnableTheming="False" Width="40%">
    <asp:ListItem Text="Item 1" Value="0" />
    <asp:ListItem Text="Item 2" Value="1" />
</asp:RadioButtonList>

Rendered result:

<table id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif" class="chxbx2" border="0" style="background-color:Transparent;border-color:Transparent;width:40%;">
  <tbody>
    <tr>
      <td>
        <input id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_0" type="radio" name="ctl00$ContentPlaceHolder$rbtnLstOptionsGenerateCertif" value="0" checked="checked">
        <label for="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_0">Item 1</label>
      </td>
      <td>
        <input id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_1" type="radio" name="ctl00$ContentPlaceHolder$rbtnLstOptionsGenerateCertif" value="1">
        <label for="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_1">Item 2</label>
      </td>
    </tr>
  </tbody>
</table>

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

Update #2:

for that true:

When TRUE, returned objects will be converted into associative arrays. for more information, click here

This function allows you to create a directory on the user home directory.

private static void createDirectory(final String directoryName) {
    final File homeDirectory = new File(System.getProperty("user.home"));
    final File newDirectory = new File(homeDirectory, directoryName);
    if(!newDirectory.exists()) {
        boolean result = newDirectory.mkdir();

        if(result) {
            System.out.println("The directory is created !");
        }
    } else {
        System.out.println("The directory already exist");
    }
}

Well, I just did

brew install mongodb

and followed the instructions that were output to the STDOUT after it finished installing, and that seems to have worked just fine. I guess it kinda works just like make install and overwrites (upgrades) a previous install.

Perform the following steps:

• Stop the Tomcat
• Right Click on Project and click on "Clean and Build"
• Go to your project Directory and inside Dist Folder you will get war file that you copy on your tomcat
• webApp Folder
• Start the tomcat
• automatic war file extract and run your project

Take a look at the INFORMATION_SCHEMA.TABLES table. It contains metadata about all your tables.

Example:

SELECT * FROM `INFORMATION_SCHEMA`.`TABLES`
WHERE TABLE_NAME LIKE 'table1'

The advantage of this over other methods is that you can easily use queries like the one above as subqueries in your other queries.

As suggested by @[Tomasz Zielinski] and @Williams python-dateutil can do it just 5 lines.

from dateutil.relativedelta import *
from datetime import date
today = date.today()
dob = date(1982, 7, 5)
age = relativedelta(today, dob)

>>relativedelta(years=+33, months=+11, days=+16)`

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

I found out that with MySQL probably the correct query is the following:

SELECT SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                 '%Y-%m-%d %H:%i:%S' ) , 1, 19 ) AS ts_CEILING,
SUM(value)
FROM group_interval
GROUP BY SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                   '%Y-%m-%d %H:%i:%S' ) , 1, 19 )
ORDER BY SUBSTRING( FROM_UNIXTIME( CEILING( timestamp /300 ) *300,  
                                   '%Y-%m-%d %H:%i:%S' ) , 1, 19 ) DESC

Let me know what you think.

you can also use

.detail_container h1:nth-of-type(1)

By changing the number 1 by any other number you can select any other h1 item.

As noted in this answer, you can check the value of document.activeElement. document is a global variable, so you don't have to do any magic to use it in your onBlur handler:

function myOnBlur(e) {
  if(document.activeElement ===
       document.getElementById('elementToCheckForFocus')) {
    // Focus went where we expected!
    // ...
  }
}

Default is:

Username: root

Password: [null]

The Password is set to 'password' in some versions.

if you don't want to create a UDF in VBA or you can't, this could be an alternative.

=Cell("Filename",A1) this will give you the full file name, and from this you could get the user name with something like this:

=Mid(A1,Find("\",A1,4)+1;Find("\";A1;Find("\";A1;4))-2)

This Formula runs only from a workbook saved earlier.

You must start from 4th position because of the first slash from the drive.

The below code reads a file, converts it to a byte array and then makes a request to the server.

    public void PostImage()
    {
        HttpClient httpClient = new HttpClient();
        MultipartFormDataContent form = new MultipartFormDataContent();

        byte[] imagebytearraystring = ImageFileToByteArray(@"C:\Users\Downloads\icon.png");
        form.Add(new ByteArrayContent(imagebytearraystring, 0, imagebytearraystring.Count()), "profile_pic", "hello1.jpg");
        HttpResponseMessage response = httpClient.PostAsync("your url", form).Result;

        httpClient.Dispose();
        string sd = response.Content.ReadAsStringAsync().Result;
    }

    private byte[] ImageFileToByteArray(string fullFilePath)
    {
        FileStream fs = File.OpenRead(fullFilePath);
        byte[] bytes = new byte[fs.Length];
        fs.Read(bytes, 0, Convert.ToInt32(fs.Length));
        fs.Close();
        return bytes;
    }

Here is yet another variant:

public static string RemoveAllWhitespace(string aString)
{
  return String.Join(String.Empty, aString.Where(aChar => aChar !Char.IsWhiteSpace(aChar)));
}

As with most of the other solutions, I haven't performed exhaustive benchmark tests, but this works well enough for my purposes.

Adding the following on top of your JS file will tell JSHint to supress the radix warning:

/*jshint -W065 */

Although it is an old question, another solution is to use datetime2 for the database column. MSDN Link

I solved this after 8 or 9 days. Just uninstall android emulator SDK(from SDK manager) and then reinstall android emulator SDK. in 8 or 9 days i tried :

1.new windows setup
2.uninstall and install android studio
3.change windows sharing setting
4.change DNS server addresses
5.delete and create some AVDs
6.delete .android folder and create new one etc.

During an object's de-serialization, the class responsible for de-serializing an object creates an instance of the serialized class and then proceeds to populate the serialized fields and properties only after acquiring an instance to populate.

You can make your constructor private or internal if you want, just so long as it's parameterless.

I had to do something similar to Sean and ilalex's answer.
But I had too many options to explicitly define the sort order for and only needed to float certain entries to the front of the list ... in the specified (non-natural) order.
Hopefully this is helpful to someone else.

public class CarComparator implements Comparator<Car> {

    //sort these items in this order to the front of the list 
    private static List<String> ORDER = Arrays.asList("dd", "aa", "cc", "bb");

    public int compare(final Car o1, final Car o2) {
        int result = 0;
        int o1Index = ORDER.indexOf(o1.getName());

I am placing JLBorges's excellent response to a similar question verbatim from cplusplus.com, as it is the most succinct explanation I've read on the subject.

In a template that we write, there are two kinds of names that could be used - dependant names and non- dependant names. A dependant name is a name that depends on a template parameter; a non-dependant name has the same meaning irrespective of what the template parameters are.

For example:

template< typename T > void foo( T& x, std::string str, int count )
{
    // these names are looked up during the second phase
    // when foo is instantiated and the type T is known
    x.size(); // dependant name (non-type)
    T::instance_count ; // dependant name (non-type)
    typename T::iterator i ; // dependant name (type)
      
    // during the first phase, 
    // T::instance_count is treated as a non-type (this is the default)
    // the typename keyword specifies that T::iterator is to be treated as a type.

    // these names are looked up during the first phase
    std::string::size_type s ; // non-dependant name (type)
    std::string::npos ; // non-dependant name (non-type)
    str.empty() ; // non-dependant name (non-type)
    count ; // non-dependant name (non-type)
}

What a dependant name refers to could be something different for each different instantiation of the template. As a consequence, C++ templates are subject to "two-phase name lookup". When a template is initially parsed (before any instantiation takes place) the compiler looks up the non-dependent names. When a particular instantiation of the template takes place, the template parameters are known by then, and the compiler looks up dependent names.

During the first phase, the parser needs to know if a dependant name is the name of a type or the name of a non-type. By default, a dependant name is assumed to be the name of a non-type. The typename keyword before a dependant name specifies that it is the name of a type.

Summary

Use the keyword typename only in template declarations and definitions provided you have a qualified name that refers to a type and depends on a template parameter.

There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:

http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html

WKWebView: I find this question to be the best place to let people know that they should start using WKWebview as UIWebView is now deprecated.

Objective C

WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.frame];
webView.navigationDelegate = self;
NSURL *nsurl=[NSURL URLWithString:@"https://www.example.com/document.pdf"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
[self.view addSubview:webView];

Swift

let myURLString = "https://www.example.com/document.pdf"
let url = NSURL(string: myURLString)
let request = NSURLRequest(URL: url!)  
let webView = WKWebView(frame: self.view.frame)
webView.navigationDelegate = self
webView.loadRequest(request)
view.addSubview(webView)

I haven't copied this code directly from Xcode, so it might, it might contain some syntax error. Please check while using it.

That should be simple. Try this:

var idList = new int[1, 2, 3, 4, 5];
var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e));

Apache Commons CSV

Check out Apache Common CSV.

This library reads and writes several variations of CSV, including the standard one RFC 4180. Also reads/writes Tab-delimited files.

• Excel
• InformixUnload
• InformixUnloadCsv
• MySQL
• Oracle
• PostgreSQLCsv
• PostgreSQLText
• RFC4180
• TDF

You need to make the strings raw and use latex:

fig.gca().set_ylabel(r'$\lambda$')

As of matplotlib 2.0 the default font supports most western alphabets and can simple do

ax.set_xlabel('?')

with unicode.

This worked for me.

using System.IO;

//  

    string readStr = File.ReadAllText(file.FullName);          
    string[] read = readStr.Split(new char[] {'\r','\n'},StringSplitOptions.RemoveEmptyEntries);

This will give you the current element name (tag name)

<xsl:value-of select ="name(.)"/>

OP-Edit: This will also do the trick:

<xsl:value-of select ="local-name()"/>

If you are using the portable XAMPP installation and Windows 7, and, like me have the version after they removed the XAMPP shell from the control panel none of the suggested answers here will do you much good as the packages will not install.

The problem is with the config file. I found the correct settings after a lot of trial and error.

Simply pull up a command window in the \xampp\php directory and run

pear config-set doc_dir :\xampp\php\docs\PEAR
pear config-set cfg_dir :\xampp\php\cfg
pear config-set data_dir :\xampp\php\data\PEAR
pear config-set test_dir :\xampp\php\tests
pear config-set www_dir :\xampp\php\www

you will want to replace the ':' with the actual drive letter that your portable drive is running on at the moment. Unfortunately, this needs to be done any time this drive letter changes, but it did get the module I needed installed.

I prefer to just return a null, and rely on the caller to handle it appropriately. The (for lack of a better word) exception is if I am absolutely 'certain' this method will return an object. In that case a failure is an exceptional should and should throw.

You can use the following command to revert all local changes:

svn st -q | awk '{print $2;}' | xargs svn revert

I wrote this so I could edit all tables and columns to null at once:

select 
case
when sc.max_length = '-1' and st.name in ('char','decimal','nvarchar','varchar')
then
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + '(MAX) NULL'
when st.name in ('char','decimal','nvarchar','varchar')
then
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + '(' + cast(sc.max_length as varchar(4)) + ') NULL'
else
'alter table  [' + so.name + '] alter column [' + sc.name + '] ' + st.name + ' NULL'
end as query
from sys.columns sc
inner join sys.types st on st.system_type_id = sc.system_type_id
inner join sys.objects so on so.object_id = sc.object_id
where so.type = 'U'
and st.name <> 'timestamp'
order by st.name

You are trying to sum up all the elements of 2-D Array

In Matlab use

Array_Sum = sum(sum(Array_Name));

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

[Quick Answer]

You can do it in 2 steps:

1. Use the checkout for create the local branch:

git checkout -b yourBranchName

2. Use the push command to autocreate the branch and send the code to the remote repository:

git push -u origin yourBranchName

There are multiple ways to do this but I think that this way is really simple.

It fires in this order.

1. = (exactly)

   location = /path

2. ^~ (forward match)

   location ^~ /path

3. ~ (regular expression case sensitive)

   location ~ /path/

4. ~* (regular expression case insensitive)

   location ~* .(jpg|png|bmp)

5. /

   location /path

You need to

#include <string>

<iostream> declares cout, cin, not string.

No. Neither Visual Studio or the .NET framework will run on Mac OSX (although the latter is changing). However, if you want to write an application in a similar framework, you could use Mono and MonoDevelop.

<script type="text/javascript">

    $('#upload').on('change',function(){
       // output raw value of file input
       $('#filename').html($(this).val().replace(/.*(\/|\\)/, '')); 

        // or, manipulate it further with regex etc.
        var filename = $(this).val().replace(/.*(\/|\\)/, '');
        // .. do your magic

        $('#filename').html(filename);
    });
</script>

If you don't want to have fix heights for your main-container (top, bottom, ....), you can simply use this css-file to get a flex-container which uses the remaining space incl. working!!! scrollbars

Here is how to get rid of the top section header in a grouped UITableView, in Swift:

tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: 0, height: CGFloat.leastNormalMagnitude))

For a seaborn.heatmap, you can rotate these using (based on @Aman's answer)

pandas_frame = pd.DataFrame(data, index=names, columns=names)
heatmap = seaborn.heatmap(pandas_frame)
loc, labels = plt.xticks()
heatmap.set_xticklabels(labels, rotation=45)
heatmap.set_yticklabels(labels[::-1], rotation=45) # reversed order for y

This error means that the value indexed by the key "l_messages" is not of type hash, but rather something else. You've probably set it to that other value earlier in your code. Try various other value-getter commands, starting with GET, to see which one works and you'll know what type is actually here.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

int[] and int* are represented the same way, except int[] allocates (IIRC).

ap is a pointer, therefore giving it the value of an integer is dangerous, as you have no idea what's at address 45.

when you try to access it (x = *ap), you try to access address 45, which causes the crash, as it probably is not a part of the memory you can access.

Quick solution I found was inside the pgAdmin program for windows. Under Tools menu there is a "Query Tool". Inside the Query Tool there is a Graphical Query Builder that can quickly show the database tables details. Good for a basic view

worked with adding $request_uri proxy_pass http://apache/$request_uri;

Try :

Configure in web config file

I like Ryan Phelan's solution. But I don't see any point of extending jQuery for that? There is no usage of jQuery functionality.

On the other hand, I like the built-in function in Google Chrome: window.location.getParameter.

So why not to use this? Okay, other browsers don't have. So let's create this function if it does not exist:

if (!window.location.getParameter ) {
  window.location.getParameter = function(key) {
    function parseParams() {
        var params = {},
            e,
            a = /\+/g,  // Regex for replacing addition symbol with a space
            r = /([^&=]+)=?([^&]*)/g,
            d = function (s) { return decodeURIComponent(s.replace(a, " ")); },
            q = window.location.search.substring(1);

        while (e = r.exec(q))
            params[d(e[1])] = d(e[2]);

        return params;
    }

    if (!this.queryStringParams)
        this.queryStringParams = parseParams(); 

    return this.queryStringParams[key];
  };
}

This function is more or less from Ryan Phelan, but it is wrapped differently: clear name and no dependencies of other javascript libraries. More about this function on my blog.

No one has explained that you can dynamically define classes. So you can have a decorator that defines (and returns) a subclass:

def addId(cls):

    class AddId(cls):

        def __init__(self, id, *args, **kargs):
            super(AddId, self).__init__(*args, **kargs)
            self.__id = id

        def getId(self):
            return self.__id

    return AddId

Which can be used in Python 2 (the comment from Blckknght which explains why you should continue to do this in 2.6+) like this:

class Foo:
    pass

FooId = addId(Foo)

And in Python 3 like this (but be careful to use super() in your classes):

@addId
class Foo:
    pass

So you can have your cake and eat it - inheritance and decorators!

Try an OUTER APPLY

SELECT 
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
FROM 
    tbl_Contents C
    OUTER APPLY
    (
        SELECT TOP 1 *
        FROM tbl_Media M 
        WHERE M.Content_Id = C.Content_Id 
    ) m
ORDER BY 
    C.Content_DatePublished ASC

Alternatively, you could GROUP BY the results

SELECT 
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
FROM 
    tbl_Contents C
    LEFT OUTER JOIN tbl_Media M ON M.Content_Id = C.Content_Id 
GROUP BY
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
ORDER BY
    C.Content_DatePublished ASC

The OUTER APPLY selects a single row (or none) that matches each row from the left table.

The GROUP BY performs the entire join, but then collapses the final result rows on the provided columns.

A user above says "well, you'll never really need to go above 10 for most designs."

Depending on your project, you may only need z-indexes 0-1, or z-indexes 0-10000. You'll often need to play in the higher digits...especially if you are working with lightbox viewers (9999 seems to be the standard and if you want to top their z-index, you'll need to exceed that!)

Chrome seems to have a bug where in certain situations, hiding elements post-load with display:none, leaves a lot of extra space behind. I would guess they are calculating document height before the document is done rendering. Chrome also fires 2 media change events, and doesn't support onbeforeprint, etc. They are basically being the ie of printing. Here's my workaround:

@media print {
    body {
        display: none;
    }
}

body.printing {
    display: block;
}

You give body class="printing" on doc ready, and that enables the print styles. This system allows for modularization of print styles, and in-browser print preview.

I generally prefer to add these codes in a function to get the Android version:

int whichAndroidVersion;

whichAndroidVersion= Build.VERSION.SDK_INT;
textView.setText("" + whichAndroidVersion); //If you don't use "" then app crashes.

For example, that code above will set the text into my textView as "29" now.

You don't have to use Calendar. You can just play with timestamps :

Date d = initDate();//intialize your date to any date 
Date dateBefore = new Date(d.getTime() - n * 24 * 3600 * 1000 l ); //Subtract n days   

UPDATE DO NOT FORGET TO ADD "l" for long by the end of 1000.

Please consider the below WARNING:

Adding 1000*60*60*24 milliseconds to a java date will once in a great while add zero days or two days to the original date in the circumstances of leap seconds, daylight savings time and the like. If you need to be 100% certain only one day is added, this solution is not the one to use.

You did everything except copying the new pixel value back to the image.

This line takes a copy of the pixel into a local variable:

Vec3b color = image.at<Vec3b>(Point(x,y));

So, after changing color as you require, just set it back like this:

image.at<Vec3b>(Point(x,y)) = color;

So, in full, something like this:

Mat image = img;
for(int y=0;y<img.rows;y++)
{
    for(int x=0;x<img.cols;x++)
    {
        // get pixel
        Vec3b & color = image.at<Vec3b>(y,x);

        // ... do something to the color ....
        color[0] = 13;
        color[1] = 13;
        color[2] = 13;

        // set pixel
        //image.at<Vec3b>(Point(x,y)) = color;
        //if you copy value
    }
}

You're on the wrong end of the Intertube. It is the server that can have only one particular port open. Some code:

  IPAddress ipAddress = Dns.GetHostEntry("localhost").AddressList[0];
  try {
    TcpListener tcpListener = new TcpListener(ipAddress, 666);
    tcpListener.Start();
  }
  catch (SocketException ex) {
    MessageBox.Show(ex.Message, "kaboom");
  }

Fails with:

Only one usage of each socket address (protocol/network address/port) is normally permitted.

I have the feeling that the check should be different

new: h < 768 || w < 1024

public static void main(String args[])
{
    Scanner s = new Scanner(System.in);

    System.out.println("Press enter to continue.....");

    s.nextLine();   
}

This nextline is a pretty good option as it will help us run next line whenever the enter key is pressed.

You can use the function:

get.elementbyId();

I think you should be able to select a disabled button using the following:

button[disabled=disabled], button:disabled {
    // your css rules
}

I work at an imaging vendor and wrote an adapter for WPF to our image format which is similar to a System.Drawing.Bitmap.

I wrote this KB to explain it to our customers:

http://www.atalasoft.com/kb/article.aspx?id=10156

And there is code there that does it. You need to replace AtalaImage with Bitmap and do the equivalent thing that we are doing -- it should be pretty straightforward.

The ContextSwitchDeadlock doesn't necessarily mean your code has an issue, just that there is a potential. If you go to Debug > Exceptions in the menu and expand the Managed Debugging Assistants, you will find ContextSwitchDeadlock is enabled. If you disable this, VS will no longer warn you when items are taking a long time to process. In some cases you may validly have a long-running operation. It's also helpful if you are debugging and have stopped on a line while this is processing - you don't want it to complain before you've had a chance to dig into an issue.

IIS7 defines a defaultDocument section in its configuration files which can be found in the %WinDir%\System32\InetSrv\Config folder. Most likely, the file index.aspx is already defined as a default document in one of IIS7's configuration files and you are adding it again in your web.config.

I suspect that removing the line <add value="index.aspx" />

from the defaultDocument/files section will fix your issue.

The defaultDocument section of your config will look like:

<defaultDocument>
  <files>
    <remove value="default.aspx" />
    <remove value="index.html" />
    <remove value="iisstart.htm" />
    <remove value="index.htm" />
    <remove value="Default.asp" />
    <remove value="Default.htm" />
  </files>
</defaultDocument>

Note that index.aspx will still appear in the list of default documents for your site in the IIS manager.

import { HttpClientModule } from '@angular/common/http';

The HttpClient API was introduced in the version 4.3.0. It is an evolution of the existing HTTP API and has it's own package @angular/common/http. One of the most notable changes is that now the response object is a JSON by default, so there's no need to parse it with map method anymore .Straight away we can use like below

http.get('friends.json').subscribe(result => this.result =result);

Select all the data and use the option "Text to Columns", that will allow your data for Applying Number Formatting ERIK

I had a similar issue, in that I only wanted return elements that were visible in a page object. I found that I'm able to use the css :not. In the case of this issue, this should do you...

expect($('i.icon-spinner:not(.ng-hide)').isDisplayed()).toBeTruthy();

In the context of a page object, you can get ONLY those elements that are visible in this way as well. Eg. given a page with multiple items, where only some are visible, you can use:

this.visibileIcons = $$('i.icon:not(.ng-hide)'); 

This will return you all visible i.icons

$.getJSON() is pretty handy for sending an AJAX request and getting back JSON data as a response. Alas, the jQuery documentation lacks a sister function that should be named $.postJSON(). Why not just use $.getJSON() and be done with it? Well, perhaps you want to send a large amount of data or, in my case, IE7 just doesn’t want to work properly with a GET request.

It is true, there is currently no $.postJSON() method, but you can accomplish the same thing by specifying a fourth parameter (type) in the $.post() function:

My code looked like this:

$.post('script.php', data, function(response) {
  // Do something with the request
}, 'json');

I ran into a problem where the browser refused to serve up content that it had retrieved when the request passed in cookies (e.g., the xhr had its withCredentials=true), and the site had Access-Control-Allow-Origin set to *. (The error in Chrome was, "Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.")

Building on the answer from @jgauffin, I created this, which is basically a way of working around that particular browser security check, so caveat emptor.

public class AllowCrossSiteJsonAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // We'd normally just use "*" for the allow-origin header, 
        // but Chrome (and perhaps others) won't allow you to use authentication if
        // the header is set to "*".
        // TODO: Check elsewhere to see if the origin is actually on the list of trusted domains.
        var ctx = filterContext.RequestContext.HttpContext;
        var origin = ctx.Request.Headers["Origin"];
        var allowOrigin = !string.IsNullOrWhiteSpace(origin) ? origin : "*";
        ctx.Response.AddHeader("Access-Control-Allow-Origin", allowOrigin);
        ctx.Response.AddHeader("Access-Control-Allow-Headers", "*");
        ctx.Response.AddHeader("Access-Control-Allow-Credentials", "true");
        base.OnActionExecuting(filterContext);
    }
}

This is an html5 error like has been said, you can still have the button as a submit (if you want to cover both javascript and non javascript users) using it like:

     <button type="submit" onclick="return false"> Register </button>

This way you will cancel the submit but still do whatever you are doing in jquery or javascript function`s and do the submit for users who dont have javascript.

Use ORACLE equivalent of getdate() which is sysdate . Read about here. Getdate() belongs to SQL Server , will not work on Oracle.

Other option is current_date

Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

Assume that foo.jsp is your jsp file. and following code is the button that you want do redirect.

<h:commandButton value="Redirect" action="#{trial.enter }"/>  

And now we'll check the method for directing in your java (service) class

 public String enter() {
            if (userName.equals("xyz") && password.equals("123")) {
                return "enter";
            } else {
                return null;
            }
        } 

and now this is a part of faces-config.xml file

<managed-bean>
        <managed-bean-name>'class_name'</managed-bean-name>
        <managed-bean-class>'package_name'</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
    </managed-bean>


    <navigation-case>
                <from-outcome>enter</from-outcome>
                <to-view-id>/foo.jsp</to-view-id>
                <redirect />
            </navigation-case>

Sometimes you can pass multiple strings separated by a space and it will be interpreted as \n.

For example when using a shell script for multi-line notifcations:

#!/bin/bash
notify-send 'notification success' 'another line' 'time now '`date +"%s"`

ps is not installed in the base wheezy image. Try this from within the container:

RUN apt-get update && apt-get install -y procps

My workabout: I use asynchronous requests dumping the code to a buffer. I have a loop checking the buffer every second. When the dump has arrived to the buffer I execute the code. I also use a timeout. For the end user the page works as if synchronous requests would be used.

One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).

What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then() on the promise, and the result will be there when the promise has been resolved.

Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:
http://www.html5rocks.com/en/tutorials/es6/promises/

You could also do this:

$dump = print_r($variable, true);

Make sure those two types are nullable DateTime

var lastPostDate = reader[3] == DBNull.Value ?
                                        null : 
                                   (DateTime?) Convert.ToDateTime(reader[3]);

• Usage of DateTime? instead of Nullable<DateTime> is a time saver...
• Use better indent of the ? expression like I did.

I have found this excellent explanations in Eric Lippert blog:

The specification for the ?: operator states the following:

The second and third operands of the ?: operator control the type of the conditional expression. Let X and Y be the types of the second and third operands. Then,

• If X and Y are the same type, then this is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from X to Y, but not from Y to X, then Y is the type of the conditional expression.

• Otherwise, if an implicit conversion exists from Y to X, but not from X to Y, then X is the type of the conditional expression.

• Otherwise, no expression type can be determined, and a compile-time error occurs.

The compiler doesn't check what is the type that can "hold" those two types.

In this case:

• null and DateTime aren't the same type.
• null doesn't have an implicit conversion to DateTime
• DateTime doesn't have an implicit conversion to null

So we end up with a compile-time error.

Swift 3

UINavigationBar.appearance().barTintColor = UIColor(colorLiteralRed: 51/255, green: 90/255, blue: 149/255, alpha: 1)

This will set your navigation bar color like Facebook bar color :)

the below function will check the column if exist return appropriate message else it will add the column to the table.

create or replace function addcol(schemaname varchar, tablename varchar, colname varchar, coltype varchar)
returns varchar 
language 'plpgsql'
as 
$$
declare 
    col_name varchar ;
begin 
      execute 'select column_name from information_schema.columns  where  table_schema = ' ||
      quote_literal(schemaname)||' and table_name='|| quote_literal(tablename) || '   and    column_name= '|| quote_literal(colname)    
      into   col_name ;   

      raise info  ' the val : % ', col_name;
      if(col_name is null ) then 
          col_name := colname;
          execute 'alter table ' ||schemaname|| '.'|| tablename || ' add column '|| colname || '  ' || coltype; 
      else
           col_name := colname ||' Already exist';
      end if;
return col_name;
end;

I encountered same problem with ORACLE 11G express on Windows. After a long time waiting I got the same error message.

My solution is to make sure the hostname in tnsnames.ora (usually it's not "localhost") and the default hostname in sql developer(usually it's "localhost") same. You can either do this by changing it in the tnsnames.ora, or filling up the same in the sql developer.

Oh, of course you need to reboot all the oracle services (just to be safe).

Hope it helps.

I came across the similar problem again on another machine, but this time above solution doesn't work. After some trying, I found restarting all the oracle related services can fix the problem. Originally when the installation is done, connection can be made. Somehow after several reboot of computer, there is problem. I change all the oracle services with start time as auto. And once I could not connect, I restart them all over again (the core service should be restarted at last order), and works fine.

Some article says it might be due to the MTS problem. Microsoft's problem. Maybe!

You need to modify your function as:

function toggleTable()
{
   if (document.getElementById("loginTable").style.display == "table" ) {
       document.getElementById("loginTable").style.display="none";

   } else {
      document.getElementById("loginTable").style.display="table";

}

currently it is checking based on the boolean parameter, you don't have to pass the parameter with your function.

You need to modify your anchor tag as:

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

How about this version in plain ES6/ES2015?

function get(url) {
  return new Promise((resolve, reject) => {
    const req = new XMLHttpRequest();
    req.open('GET', url);
    req.onload = () => req.status === 200 ? resolve(req.response) : reject(Error(req.statusText));
    req.onerror = (e) => reject(Error(`Network Error: ${e}`));
    req.send();
  });
}

The function returns a promise. Here is an example on how to use the function and handle the promise it returns:

get('foo.txt')
.then((data) => {
  // Do stuff with data, if foo.txt was successfully loaded.
})
.catch((err) => {
  // Do stuff on error...
});

If you need to load a json file you can use JSON.parse() to convert the loaded data into an JS Object.

You can also integrate req.responseType='json' into the function but unfortunately there is no IE support for it, so I would stick with JSON.parse().

Makefile.am is a programmer-defined file and is used by automake to generate the Makefile.in file (the .am stands for automake). The configure script typically seen in source tarballs will use the Makefile.in to generate a Makefile.

The configure script itself is generated from a programmer-defined file named either configure.ac or configure.in (deprecated). I prefer .ac (for autoconf) since it differentiates it from the generated Makefile.in files and that way I can have rules such as make dist-clean which runs rm -f *.in. Since it is a generated file, it is not typically stored in a revision system such as Git, SVN, Mercurial or CVS, rather the .ac file would be.

Read more on GNU Autotools. Read about make and Makefile first, then learn about automake, autoconf, libtool, etc.

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

DateTime.Now.DayOfWeek quite easy to guess actually.

for any given date:

   DateTime dt = //....
   DayOfWeek dow = dt.DayOfWeek; //enum
   string str = dow.ToString(); //string

Here it is using jQuery. See it in action at http://jsfiddle.net/sQnSZ/

<button id="x">test</button>

$('#x').click(function(){
    location.href='http://cnn.com'
})

No need to store it anywhere. Just output the content with the appropriate content type.

<?php
    header('Content-type: text/plain');
?>Hello, world.

Add content-disposition if you wish to trigger a download prompt.

header('Content-Disposition: attachment; filename="default-filename.txt"');

I believe you should escape the dot. Try:

String filename = "D:/some folder/001.docx";
String extensionRemoved = filename.split("\\.")[0];

Otherwise dot is interpreted as any character in regular expressions.

You don't want to stringify large objects into a single localStorage entry. That would be very inefficient - the whole thing would have to be parsed and re-encoded every time some slight detail changes. Also, JSON can't handle multiple cross references within an object structure and wipes out a lot of details, e.g. the constructor, non-numerical properties of arrays, what's in a sparse entry, etc.

Instead, you can use Rhaboo. It stores large objects using lots of localStorage entries so you can make small changes quickly. The restored objects are much more accurate copies of the saved ones and the API is incredibly simple. E.g.:

var store = Rhaboo.persistent('Some name');
store.write('count', store.count ? store.count+1 : 1);
store.write('somethingfancy', {
  one: ['man', 'went'],
  2: 'mow',
  went: [  2, { mow: ['a', 'meadow' ] }, {}  ]
});
store.somethingfancy.went[1].mow.write(1, 'lawn');

BTW, I wrote it.

You just have to use class="row-eq-height" with your class="row" to get equal height columns for previous bootstrap versions.

but with bootstrap 4 this comes natively.

check this link --http://getbootstrap.com.vn/examples/equal-height-columns/

You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest(). A function to do this would look like the following:

def File_Checksum_Dis(dirname):
    
    if not os.path.exists(dirname):
        print(dirname+" directory is not existing");
    
    for fname in os.listdir(dirname):
        if not fname.endswith('~'):
            fnaav = os.path.join(dirname, fname);
            fd = open(fnaav, 'rb');
            data = fd.read();
            fd.close();
        
            print("-"*70);
            print("File Name is: ",fname);          
            print(hashlib.md5(data).hexdigest())
            print("-"*70);
                

I've developed a tool called Doxygraph which can parse the XML generated by Doxygen and turn it into an interactive UML class diagram which you can view in a web browser or import into any software that can read Graphviz "dot" files.

By.cssSelector(".ban") or By.cssSelector(".hot") or By.cssSelector(".ban.hot") should all select it unless there is another element that has those classes.

In CSS, .name means find an element that has a class with name. .foo.bar.baz means to find an element that has all of those classes (in the same element).

However, each of those selectors will select only the first element that matches it on the page. If you need something more specific, please post the HTML of the other elements that have those classes.

Use double quotes while using BASH variables.

mysql --user="$user" --password="$password" --database="$database" --execute="DROP DATABASE $user; CREATE DATABASE $database;"

BASH doesn't expand variables in single quotes.

Firstly you need to install a SSH server in the images you wish to ssh-into. You can use a base image for all your container with the ssh server installed. Then you only have to run each container mapping the ssh port (default 22) to one to the host's ports (Remote Server in your image), using -p <hostPort>:<containerPort>. i.e:

docker run -p 52022:22 container1 
docker run -p 53022:22 container2

Then, if ports 52022 and 53022 of host's are accessible from outside, you can directly ssh to the containers using the ip of the host (Remote Server) specifying the port in ssh with -p <port>. I.e.:

ssh -p 52022 myuser@RemoteServer --> SSH to container1

ssh -p 53022 myuser@RemoteServer --> SSH to container2

Many answers here tells to delete a specific k8s object, but you can delete multiple objects at once, instead of one by one:

kubectl delete deployments,jobs,services,pods --all -n <namespace>

In my case, I'm running OpenShift cluster with OLM - Operator Lifecycle Manager. OLM is the one who controls the deployment, so when I deleted the deployment, it was not sufficient to stop the pods from restarting.

Only when I deleted OLM and its subscription, the deployment, services and pods were gone.

First list all k8s objects in your namespace:

$ kubectl get all -n openshift-submariner

NAME                                       READY   STATUS    RESTARTS   AGE
pod/submariner-operator-847f545595-jwv27   1/1     Running   0          8d  
NAME                                  TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
service/submariner-operator-metrics   ClusterIP   101.34.190.249   <none>        8383/TCP   8d
NAME                                  READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/submariner-operator   1/1     1            1           8d
NAME                                             DESIRED   CURRENT   READY   AGE
replicaset.apps/submariner-operator-847f545595   1         1         1       8d

OLM is not listed with get all, so I search for it specifically:

$ kubectl get olm -n openshift-submariner

NAME                                                      AGE
operatorgroup.operators.coreos.com/openshift-submariner   8d
NAME                                                             DISPLAY      VERSION
clusterserviceversion.operators.coreos.com/submariner-operator   Submariner   0.0.1 

Now delete all objects, including OLMs, subscriptions, deployments, replica-sets, etc:

$ kubectl delete olm,svc,rs,rc,subs,deploy,jobs,pods --all -n openshift-submariner

operatorgroup.operators.coreos.com "openshift-submariner" deleted
clusterserviceversion.operators.coreos.com "submariner-operator" deleted
deployment.extensions "submariner-operator" deleted
subscription.operators.coreos.com "submariner" deleted
service "submariner-operator-metrics" deleted
replicaset.extensions "submariner-operator-847f545595" deleted
pod "submariner-operator-847f545595-jwv27" deleted

List objects again - all gone:

$ kubectl get all -n openshift-submariner
No resources found.

$ kubectl get olm -n openshift-submariner
No resources found.

We have some generic playbooks that are usable by a large number of teams. We also have environment specific inventory files, that contain multiple group declarations.

To force someone calling a playbook to specify a group to run against, we seed a dummy entry at the top of the playbook:

[ansible-dummy-group]
dummy-server

We then include the following check as a first step in the shared playbook:

- hosts: all
  gather_facts: False
  run_once: true
  tasks:
  - fail:
      msg: "Please specify a group to run this playbook against"
    when: '"dummy-server" in ansible_play_batch'

If the dummy-server shows up in the list of hosts this playbook is scheduled to run against (ansible_play_batch), then the caller didn't specify a group and the playbook execution will fail.
