The difference is:
- orphanRemoval = true: "Child" entity is removed when it's no longer referenced (its parent may not be removed).
- CascadeType.REMOVE: "Child" entity is removed only when its "Parent" is removed.

A foreign key with a cascade delete means that if a record in the parent table is deleted, then the corresponding records in the child table will automatically be deleted. This is called a cascade delete.

You are saying in a opposite way, this is not that when you delete from child table then records will be deleted from parent table.

UPDATE 1:

ON DELETE CASCADE option is to specify whether you want rows deleted in a child table when corresponding rows are deleted in the parent table. If you do not specify cascading deletes, the default behaviour of the database server prevents you from deleting data in a table if other tables reference it.

If you specify this option, later when you delete a row in the parent table, the database server also deletes any rows associated with that row (foreign keys) in a child table. The principal advantage to the cascading-deletes feature is that it allows you to reduce the quantity of SQL statements you need to perform delete actions.

So it's all about what will happen when you delete rows from Parent table not from child table.

So in your case when user removes entries from CATs table then rows will be deleted from books table. :)

Hope this helps you :)

See here for an example from the OpenJPA docs. CascadeType.ALL means it will do all actions.

Quote:

CascadeType.PERSIST: When persisting an entity, also persist the entities held in its fields. We suggest a liberal application of this cascade rule, because if the EntityManager finds a field that references a new entity during the flush, and the field does not use CascadeType.PERSIST, it is an error.

CascadeType.REMOVE: When deleting an entity, it also deletes the entities held in this field.

CascadeType.REFRESH: When refreshing an entity, also refresh the entities held in this field.

CascadeType.MERGE: When merging entity state, also merge the entities held in this field.

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

Cascade will work when you delete something on table Courses. Any record on table BookCourses that has reference to table Courses will be deleted automatically.

But when you try to delete on table BookCourses only the table itself is affected and not on the Courses

follow-up question: why do you have CourseID on table Category?

Maybe you should restructure your schema into this,

CREATE TABLE Categories 
(
  Code CHAR(4) NOT NULL PRIMARY KEY,
  CategoryName VARCHAR(63) NOT NULL UNIQUE
);

CREATE TABLE Courses 
(
  CourseID INT NOT NULL PRIMARY KEY,
  BookID INT NOT NULL,
  CatCode CHAR(4) NOT NULL,
  CourseNum CHAR(3) NOT NULL,
  CourseSec CHAR(1) NOT NULL,
);

ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)
REFERENCES Categories(Code)
ON DELETE CASCADE;

If you're looking to match non-blank values or empty cells and having difficulty with wildcard character, I found the solution below from here.

Dim n as Integer
n = Worksheets("Sheet1").Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count

I use this command:

mount -o rw,remount /system

If you're using Android Studio for Windows to create a release keystore and signed .apk, just follow these steps:

1) Build > Generate Signed APK

2) Choose "Create New...", choose the path to the keystore, and enter all the required data

3) After your keystore (your_keystore_name.jks) has been created, you will then use it to create your first signed apk at a destination of your choosing

I haven't seen a need to use the command tool if you have an IDE like Android Studio.

FWIW, you can provide an error message like so:

USERNAME=${1:?"Specify a username"}

This displays a message like this and exits with code 1:

./myscript.sh
./myscript.sh: line 2: 1: Specify a username

A more complete example of everything:

#!/bin/bash
ACTION=${1:?"Specify 'action' as argv[1]"}
DIRNAME=${2:-$PWD}
OUTPUT_DIR=${3:-${HOMEDIR:-"/tmp"}}

echo "$ACTION"
echo "$DIRNAME"
echo "$OUTPUT_DIR"

Output:

$ ./script.sh foo
foo
/path/to/pwd
/tmp

$ export HOMEDIR=/home/myuser
$ ./script.sh foo
foo
/path/to/pwd
/home/myuser

• $ACTION takes the value of the first argument, and exits if empty
• $DIRNAME is the 2nd argument, and defaults to the current directory
• $OUTPUT_DIR is the 3rd argument, or $HOMEDIR (if defined), else, /tmp. This works on OS X, but I'm not positive that it's portable.

Method A is recommended by httpclient developer community.

NULL == NULL -> false (at least in DBMSs)

So you wouldn't be able to retrieve any relationships using a NULL value even with additional columns with real values.

Whatsapp store all messages in an encrypted database (pyCrypt) which is very easy to decipher using Python.

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.

You need to name the entity that holds the association to User. For example,

... INNER JOIN ug.user u ...

That's the "path" the error message is complaining about -- path from UserGroup to User entity.

Hibernate relies on declarative JOINs, for which the join condition is declared in the mapping metadata. This is why it is impossible to construct the native SQL query without having the path.

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

If you want to store multiple values for a key (if I understand you correctly), you could try a MultiHashMap (available in various libraries, not only commons-collections).

One simple way can be the use of assign() function that is pre-defined in vector class.

e.g.

array[5]={1,2,3,4,5};

vector<int> v;
v.assign(array, array+5); // 5 is size of array.

I think you might not see fractals as an algorithm or something to program. Fractals is a concept! It is a mathematical concept of detailed pattern repeating itself.

Therefore you can create a fractal in many ways, using different approaches, as shown in the image below.

Choose an approach and then investigate how to implement it. These four examples were implemented using Marvin Framework. The source codes are available here

I kept getting this error, when using wildcard subdomains with my app. I had the site url set to: http://myapp.com and app domain also to http://myapp.com, and also the same value for the Valid OAuth redirect URIs in the advanced tab of the settings app. I tried different combinations but only setting the http://subdomain.myapp.com as the redirect value worked, of course only for that subdomain.

The solution was to empty the redirect fields, leave it blank, that worked! ;)

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

Why not just do it in css?

Take out the 'href' attribute in your anchor tag

<ul class="product-info">
  <li>
    <a>YOU CLICK THIS TO SHOW/HIDE</a>
    <div class="toggle">
      <p>CONTENT TO SHOW/HIDE</p>
    </div>
  </li>
</ul>

In your css,

  a{
    cursor: pointer;
    }

What do you mean, the error only shows up when you assign? For example on GCC, with no assignment in sight:

int main() {
    struct blah *b = 0;
    *b; // this is line 6
}

incompletetype.c:6: error: dereferencing pointer to incomplete type.

The error is at line 6, that's where I used an incomplete type as if it were a complete type. I was fine up until then.

The mistake is that you should have included whatever header defines the type. But the compiler can't possibly guess what line that should have been included at: any line outside of a function would be fine, pretty much. Neither is it going to go trawling through every text file on your system, looking for a header that defines it, and suggest you should include that.

Alternatively (good point, potatoswatter), the error is at the line where b was defined, when you meant to specify some type which actually exists, but actually specified blah. Finding the definition of the variable b shouldn't be too difficult in most cases. IDEs can usually do it for you, compiler warnings maybe can't be bothered. It's some pretty heinous code, though, if you can't find the definitions of the things you're using.

pip is designed to upgrade python packages and not to upgrade python itself. pip shouldn't try to upgrade python when you ask it to do so.

Don't type pip install python but use an installer instead.

On https://help.directadmin.com/item.php?id=589 they write:

If you need a quick way to reset your public_html data to 755 for directories and 644 for files, then you can use something like this:

cd /home/user/domains/domain.com/public_html
find . -type d -exec chmod 0755 {} \;
find . -type f -exec chmod 0644 {} \;

I tested and ... it works!

Thanks to Service Workers, it is possible to implement a solution similar to Adam's purely on the client-side, granted the browser supports it. Just circumvent heartbeat requests:

// The delay should be longer than the heartbeat by a significant enough amount that there won't be false positives
const liveTimeoutDelay = 10000
let liveTimeout = null

global.self.addEventListener('fetch', event => {
  clearTimeout(liveTimeout)
  liveTimeout = setTimeout(() => {
    console.log('User left page')
    // handle page leave
  }, liveTimeoutDelay)
  // Forward any events except for hearbeat events
  if (event.request.url.endsWith('/heartbeat')) {
    event.respondWith(
      new global.Response('Still here')
    )
  }
})

First install the composer like mentioned in the composer installation documentation. I just added here for reference.

curl -sS https://getcomposer.org/installer | php

and then move the file to '/usr/local/bin'.

sudo mv composer.phar /usr/local/bin/composer

Try to run composer -V. If you get a output like Composer version followed by the version number then the composer is installed successfully.

If you get any output like composer: command not found means use the following command to create a alias for the composer. So it will be executed globally.

alias composer='/usr/local/bin/composer'

Now if you run composer -V means you will get the output as Composer Version followed by the version number.

Hope this will help someone.

The actual way to end a program, is to call

raise SystemExit

It's what sys.exit does, anyway.

A plain SystemExit, or with None as a single argument, sets the process' exit code to zero. Any non-integer exception value (raise SystemExit("some message")) prints the exception value to sys.stderr and sets the exit code to 1. An integer value sets the process' exit code to the value:

$ python -c "raise SystemExit(4)"; echo $?
4

I needed a NSNumber object containing the exact result of [[NSDate date] timeIntervalSince1970]. Since this function was called many times and I didn't really need to create an NSDate object, performance was not great.

So to get the format that the original function was giving me, try this:

#include <sys/time.h>
struct timeval tv;
gettimeofday(&tv,NULL);
double perciseTimeStamp = tv.tv_sec + tv.tv_usec * 0.000001;

Which should give you the exact same result as [[NSDate date] timeIntervalSince1970]

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

this also done the trick.

another way to get exactly the output mentioned in the question:

envtext= "printenv".execute().text
envtext.split('\n').each
{   envvar=it.split("=")
    println envvar[0]+" is "+envvar[1]
}

This can easily be extended to build a map with a subset of env vars matching a criteria:

envdict=[:]
envtext= "printenv".execute().text
envtext.split('\n').each
{   envvar=it.split("=")
    if (envvar[0].startsWith("GERRIT_"))
        envdict.put(envvar[0],envvar[1])
}    
envdict.each{println it.key+" is "+it.value}

Add in the generated migration after creating the column the following (example)

I know this has already been answered. But I would like to add my solution as it may helpful for others in the future..

A common key error is: Permission denied (publickey). You can fix this by using keys:add to notify Heroku of your new key.

In short follow these steps: https://devcenter.heroku.com/articles/keys

First you have to create a key if you don't have one:

ssh-keygen -t rsa

Second you have to add the key to Heroku:

heroku keys:add

object.sendKeys("your message", Keys.ENTER);

It works.

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

In order to put the number in the correct order i modified your code to have a variable (s) for the output. This allows you to put the characters in the correct order.

s=""
def ChangeHex(n):
    if (n < 0):
        print(0)
    elif (n<=1):
        print(n)
    else:
        x =(n%16)
        if (x < 10):
            s=str(x)+s, 
        if (x == 10):
            s="A"+s,
        if (x == 11):
            s="B"+s,
        if (x == 12):
            s="C"+s,
        if (x == 13):
            s="D"+s,
        if (x == 14):
            s="E"+s,
        if (x == 15):
            s="F"+s,
        ChangeHex( n / 16 )        

NOTE: This was done in python 3.7.4 so it may not work for you.

If you want to select the columns from First Table "which are also present in Second table, then in this case you can also use EXCEPT. In this case, column names can be different as well but data type should be same.

Example:

select ID, FName
from FirstTable
EXCEPT
select ID, SName
from SecondTable

You could do it like this

var a, b
var foo = {
    a: a = 5,
    b: b = 6,
    c: a + b
}

That method has proven useful to me when I had to refer to the object that a function was originally declared on. The following is a minimal example of how I used it:

function createMyObject() {
    var count = 0, self
    return {
        a: self = {
            log: function() {
                console.log(count++)
                return self
            }
        }
    }
}

By defining self as the object that contains the print function you allow the function to refer to that object. This means you will not have to 'bind' the print function to an object if you need to pass it somewhere else.

If you would, instead, use this as illustrated below

function createMyObject() {
    var count = 0
    return {
        a: {
            log: function() {
                console.log(count++)
                return this
            }
        }
    }
}

Then the following code will log 0, 1, 2 and then give an error

var o = createMyObject()
var log = o.a.log
o.a.log().log() // this refers to the o.a object so the chaining works
log().log() // this refers to the window object so the chaining fails!

By using the self method you guarantee that print will always return the same object regardless of the context in which the function is ran. The code above will run just fine and log 0, 1, 2 and 3 when using the self version of createMyObject().

You can also try figlegend. It is possible to create a legend independent of any Axes object. However, you may need to create some "dummy" Paths to make sure the formatting for the objects gets passed on correctly.

If there's only some few components of your webview that is slow or laggy, try adding this to the elements css:

transform: translate3d(0,0,0);
-webkit-transform: translate3d(0,0,0);

This has been the only speedhack that really had a effect on my webview. But be careful not to overuse it! (you can read more about the hack in this article.)

I used (the suggested answer from above)

sudo apt-get install eclipse eclipse-cdt g++

but ONLY after then also doing

sudo eclipse -clean

Hope that also helps.

A slight variation on andrew.fox answer, as the string to decode might not be a correct base64 encoded string:

using System;

namespace Service.Support
{
    public static class Base64
    {
        public static string ToBase64(this System.Text.Encoding encoding, string text)
        {
            if (text == null)
            {
                return null;
            }

            byte[] textAsBytes = encoding.GetBytes(text);
            return Convert.ToBase64String(textAsBytes);
        }

        public static bool TryParseBase64(this System.Text.Encoding encoding, string encodedText, out string decodedText)
        {
            if (encodedText == null)
            {
                decodedText = null;
                return false;
            }

            try
            {
                byte[] textAsBytes = Convert.FromBase64String(encodedText);
                decodedText = encoding.GetString(textAsBytes);
                return true;
            }
            catch (Exception)
            {
                decodedText = null;
                return false;   
            }
        }
    }
}

You can use the TelephonyManager to do this:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

You'll need to give your application permission to make this query by adding the following to your Manifest:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)

The language used by Facebook is PHP.

Also, do any other social networking sites use the same language?

The other one I know of is friendster.

More simple:

return (byte[])System.ComponentModel.TypeDescriptor.GetConverter(pImagen).ConvertTo(pImagen, typeof(byte[]))

Try doing:

SHOW TABLE STATUS FROM credentialing1;

The foreign key constraints are listed in the Comment column of the output.

The difference is that miniconda is just shipping the repository management system. So when you install it there is just the management system without packages. Whereas with Anaconda, it is like a distribution with some built in packages.

Like with any Linux distribution, there are some releases which bundles lots of updates for the included packages. That is why there is a difference in version numbering. If you only decide to upgrade Anaconda, you are updating a whole system.

@media screen and (max-width:480px) { … } 

screen here is to set the screen size of the media query. E.g the maximum width of the display area is 480px. So it is specifying the screen as opposed to the other available media types.

@media only screen and (max-width: 480px;) { … } 

only screen here is used to prevent older browsers that do not support media queries with media features from applying the specified styles.

In the first line of your JS code:

select.addEventListener('change', getSelection(this), false);

you're invoking getSelection by placing (this) behind the function reference. That is most likely not what you want, because you're now passing the return value of that call to addEventListener, instead of a reference to the actual function itself.

In a function invoked by addEventListener the value for this will automatically be set to the object the listener is attached to, productLineSelect in this case.

If that is what you want, you can just pass the function reference and this will in this example be select in invocations from addEventListener:

select.addEventListener('change', getSelection, false);

If that is not what you want, you'd best bind your value for this to the function you're passing to addEventListener:

var thisArg = { custom: 'object' };
select.addEventListener('change', getSelection.bind(thisArg), false);

The .bind part is also a call, but this call just returns the same function we're calling bind on, with the value for this inside that function scope fixed to thisArg, effectively overriding the dynamic nature of this-binding.

To get to your actual question: "How to pass parameters to function in addEventListener?"

You would have to use an additional function definition:

var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}, false);

Now we pass the event object, a reference to the value of this inside the callback of addEventListener, a variable defined and initialised inside that callback, and a variable from outside the entire addEventListener call to your own getSelection function.

We also might again have an object of our choice to be this inside the outer callback:

var thisArg = { custom: 'object' };
var globalVar = 'global';

productLineSelect.addEventListener('change', function(event) {
    var localVar = 'local';
    getSelection(event, this, globalVar, localVar);
}.bind(thisArg), false);

Several answers above work. I wanted an approach that I did not have to keep making code changes and did not make my code unsecure. Hence I created a whitelist. Whitelist can be maintained in any datastore. I used config file since it is a very small list.

My code is below.

ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, error) => {
    return error == System.Net.Security.SslPolicyErrors.None || certificateWhitelist.Contains(cert.GetCertHashString());
};

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

Well its a sequential process. The Request first treat by FrontController and then moves towards our own customize controller with @Controller annotation.

but our controller method is binding bean using modelattribute and we are also performing few validations on bean values.

so instead of moving the request to our controller class, FrontController moves it towards one interceptor which creates the temp object of our bean and the validate the values. if validation successful then bind the temp obj values with our actual bean which is stored in @ModelAttribute otherwise if validation fails it does not bind and moves the resp towards error page or wherever u want.

Complement of information for those people who use .on() to listen to events bound on inputs inside lately loaded table cells; I managed to bind event handlers to such table cells by using delegate(), but .on() wouldn't work.

I bound the table id to .delegate() and used a selector that describes the inputs.

e.g.

HTML

<table id="#mytable">
  <!-- These three lines below were loaded post-DOM creation time, using a live callback for example -->
  <tr><td><input name="qty_001" /></td></tr>
  <tr><td><input name="qty_002" /></td></tr>
  <tr><td><input name="qty_003" /></td></tr>
</table>

jQuery

$('#mytable').delegate('click', 'name^=["qty_"]', function() {
    console.log("you clicked cell #" . $(this).attr("name"));
});

When you run git commit with no arguments, it will open your default editor to allow you to type a commit message. Saving the file and quitting the editor will make the commit.

It looks like your default editor is Vi or Vim. The reason "weird stuff" happens when you type is that Vi doesn't start in insert mode - you have to hit i on your keyboard first! If you don't want that, you can change it to something simpler, for example:

git config --global core.editor nano

Then you'll load the Nano editor (assuming it's installed!) when you commit, which is much more intuitive for users who've not used a modal editor such as Vi.

That text you see on your screen is just to remind you what you're about to commit. The lines are preceded by # which means they're comments, i.e. Git ignores those lines when you save your commit message. You don't need to type a message per file - just enter some text at the top of the editor's buffer.

To bypass the editor, you can provide a commit message as an argument, e.g.

git commit -m "Added foo to the bar"

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

Assuming you were branching from the master, you don't need to enter yourBranch into the reset step all the time:

git checkout yourBranch
git reset --soft HEAD~$(git rev-list --count HEAD ^master)
git add -A
git commit -m "one commit on yourBranch"

Explanation:

• git rev-list --count HEAD ^master counts the commits since you made your feature branch from the master, f.ex. 20.
• git reset --soft HEAD~20 will make a soft reset of the last 20 commits. This leaves your changes in the files, but removes the commits.

Usage:

In my .bash_profile I have added an alias for gisquash to do this with one command:

# squash all commits into one
alias gisquash='git reset --soft HEAD~$(git rev-list --count HEAD ^master)'

After reseting and committing you need to do a git push --force.

Hint:

If you're using Gitlab >= 11.0 you don't need to do this anymore as it has a squashing option when merging branches.

First things first :) reading books is an excellent approach to problem solving; it's the difference between band-aid fixes and long-term investments in solving problems. Never miss an opportunity to learn. :D

You might choose to interpret the 1 as a number, but environment variables don't care. They just pass around strings:

   The argument envp is an array of character pointers to null-
   terminated strings. These strings shall constitute the
   environment for the new process image. The envp array is
   terminated by a null pointer.

(From environ(3posix).)

You access environment variables in python using the os.environ dictionary-like object:

>>> import os
>>> os.environ["HOME"]
'/home/sarnold'
>>> os.environ["PATH"]
'/home/sarnold/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games'
>>> os.environ["PATH"] = os.environ["PATH"] + ":/silly/"
>>> os.environ["PATH"]
'/home/sarnold/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/silly/'

This thread is kind of old, and most of what I want to share is already here.

However, my favorite method is not mentioned, and AFAIK there’s no native support in the current Clang, so here I go…

First, and foremost (as others have pointed out already) abstract classes are something very uncommon in Objective-C — we usually use composition (sometimes through delegation) instead. This is probably the reason why such a feature doesn’t already exist in the language/compiler — apart from @dynamic properties, which IIRC have been added in ObjC 2.0 accompanying the introduction of CoreData.

But given that (after careful assessment of your situation!) you have come to the conclusion that delegation (or composition in general) isn’t well suited to solving your problem, here’s how I do it:

1. Implement every abstract method in the base class.
2. Make that implementation [self doesNotRecognizeSelector:_cmd];…
3. …followed by __builtin_unreachable(); to silence the warning you’ll get for non-void methods, telling you “control reached end of non-void function without a return”.
4. Either combine steps 2. and 3. in a macro, or annotate -[NSObject doesNotRecognizeSelector:] using __attribute__((__noreturn__)) in a category without implementation so as not to replace the original implementation of that method, and include the header for that category in your project’s PCH.

I personally prefer the macro version as that allows me to reduce the boilerplate as much as possible.

Here it is:

// Definition:
#define D12_ABSTRACT_METHOD {\
 [self doesNotRecognizeSelector:_cmd]; \
 __builtin_unreachable(); \
}

// Usage (assuming we were Apple, implementing the abstract base class NSString):
@implementation NSString

#pragma mark - Abstract Primitives
- (unichar)characterAtIndex:(NSUInteger)index D12_ABSTRACT_METHOD
- (NSUInteger)length D12_ABSTRACT_METHOD
- (void)getCharacters:(unichar *)buffer range:(NSRange)aRange D12_ABSTRACT_METHOD

#pragma mark - Concrete Methods
- (NSString *)substringWithRange:(NSRange)aRange
{
    if (aRange.location + aRange.length >= [self length])
        [NSException raise:NSInvalidArgumentException format:@"Range %@ exceeds the length of %@ (%lu)", NSStringFromRange(aRange), [super description], (unsigned long)[self length]];

    unichar *buffer = (unichar *)malloc(aRange.length * sizeof(unichar));
    [self getCharacters:buffer range:aRange];

    return [[[NSString alloc] initWithCharactersNoCopy:buffer length:aRange.length freeWhenDone:YES] autorelease];
}
// and so forth…

@end

As you can see, the macro provides the full implementation of the abstract methods, reducing the necessary amount of boilerplate to an absolute minimum.

An even better option would be to lobby the Clang team to providing a compiler attribute for this case, via feature requests. (Better, because this would also enable compile-time diagnostics for those scenarios where you subclass e.g. NSIncrementalStore.)

Why I Choose This Method

1. It get’s the job done efficiently, and somewhat conveniently.
2. It’s fairly easy to understand. (Okay, that __builtin_unreachable() may surprise people, but it’s easy enough to understand, too.)
3. It cannot be stripped in release builds without generating other compiler warnings, or errors — unlike an approach that’s based on one of the assertion macros.

That last point needs some explanation, I guess:

Some (most?) people strip assertions in release builds. (I disagree with that habit, but that’s another story…) Failing to implement a required method — however — is bad, terrible, wrong, and basically the end of the universe for your program. Your program cannot work correctly in this regard because it is undefined, and undefined behavior is the worst thing ever. Hence, being able to strip those diagnostics without generating new diagnostics would be completely unacceptable.

It’s bad enough that you cannot obtain proper compile-time diagnostics for such programmer errors, and have to resort to at-run-time discovery for these, but if you can plaster over it in release builds, why try having an abstract class in the first place?

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

double ToRadians(double degrees) 
{
  double radians = degrees * LOCAL_PI / 180;
  return radians;
}

double DirectDistance(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 3958.75;
  double dLat = ToRadians(lat2-lat1);
  double dLng = ToRadians(lng2-lng1);
  double a = sin(dLat/2) * sin(dLat/2) + 
             cos(ToRadians(lat1)) * cos(ToRadians(lat2)) * 
             sin(dLng/2) * sin(dLng/2);
  double c = 2 * atan2(sqrt(a), sqrt(1-a));
  double dist = earthRadius * c;
  double meterConversion = 1609.00;
  return dist * meterConversion;
}

In your spring class, You can inject a bean annotated like as

@Autowired
@Qualifier("dbDataSource")
private DataSource dataSource;

and You add this in your context.xml

<beans:bean id="dbDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <beans:property name="jndiName" value="java:comp/env/jdbc/MyLocalDB"/>
</beans:bean>

You can declare the JNDI resource in tomcat's server.xml using

<Resource name="jdbc/TestDB" 
  global="jdbc/TestDB" 
  auth="Container" 
  type="javax.sql.DataSource" 
  driverClassName="com.mysql.jdbc.Driver" 
  url="jdbc:mysql://localhost:3306/TestDB" 
  username="pankaj" 
  password="pankaj123" 

  maxActive="100" 
  maxIdle="20" 
  minIdle="5" 
  maxWait="10000"/>

back to context.xml de spring add this

if, like this exmple you are injecting connection to database, make sure that MySQL jar is present in the tomcat lib directory, otherwise tomcat will not be able to create the MySQL database connection pool.

"Visual Studio does not support std::cout as debug tool for non-console applications"
_{- from Marius Amado-Alves' answer to "How can I see cout output in a non-console application?"}

Which means if you use it, Visual Studio shows nothing in the "output" window (in my case VS2008)

EDIT:

The gcc guys really improved the diagnosis experience in gcc (ah competition). They created a wiki page to showcase it here. gcc 4.8 now has quite good diagnostics as well (gcc 4.9x added color support). Clang is still in the lead, but the gap is closing.

Original:

For students, I would unconditionally recommend Clang.

The performance in terms of generated code between gcc and Clang is now unclear (though I think that gcc 4.7 still has the lead, I haven't seen conclusive benchmarks yet), but for students to learn it does not really matter anyway.

On the other hand, Clang's extremely clear diagnostics are definitely easier for beginners to interpret.

Consider this simple snippet:

#include <string>
#include <iostream>

struct Student {
std::string surname;
std::string givenname;
}

std::ostream& operator<<(std::ostream& out, Student const& s) {
  return out << "{" << s.surname << ", " << s.givenname << "}";
}

int main() {
  Student me = { "Doe", "John" };
  std::cout << me << "\n";
}

You'll notice right away that the semi-colon is missing after the definition of the Student class, right :) ?

Well, gcc notices it too, after a fashion:

prog.cpp:9: error: expected initializer before ‘&’ token
prog.cpp: In function ‘int main()’:
prog.cpp:15: error: no match for ‘operator<<’ in ‘std::cout << me’

And Clang is not exactly starring here either, but still:

I purposefully choose an example which triggers an unclear error message (coming from an ambiguity in the grammar) rather than the typical "Oh my god Clang read my mind" examples. Still, we notice that Clang avoids the flood of errors. No need to scare students away.

I remember someday that I spent a lot of time trying to center a div, using margin: 0 auto.

I had display: inline-block on it, when I removed it, the div centered correctly.

As Ross pointed out, it doesn't work on inline elements.

One point is that this is a good coding approach. It satisfies many OOP principles, eg., SRP, Separation of concerns etc.

So, the view controller presenting the view should be the one dismissing it.

Like, a real estate company who gives a house on rent should be the authority to take it back.

After a few futile hours battling with a 'SyntaxError: missing : after property id' message I can now expand on this topic:

border-width is a valid css property but it is not included in the jQuery css oject definition, so .css({border-width: '2px'}) will cause an error, but it's quite happy with .css({'border-width': '2px'}), presumably property names in quotes are just passed on as received.

For the php_intl.dll extension to work correctly, you need to have the following files in a folder in your PATH:

• icudt36.dll
• icuin36.dll
• icuio36.dll
• icule36.dll
• iculx36.dll
• icutu36.dll
• icuuc36.dll

By default they're sitting in your PHP directory, but that directory isn't necessarily in your PATH (it wasn't for me, using xampp)

This has to be in your global path, not just your user's path. To set the global path, go to system info (windows key + PAUSE), then Advanced System Settings (Vista+) or Advanced (XP) and click the "Environment Variables" button and add the appropriate directory to the PATH variable in the System Variables list.

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

Go to the flask file in microblog, then activate the virtual environment with source bin/activate, then go to flask/bin and install flask, and the rest of the packages, pip install flask. You will see flask listed inside bin directory. Try to run ./run.py again from microblog (or from wherever you have the file).

to convert a TimestampTZ in oracle, you do

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

I am having the same problem, I found the below on the web somewhere....

Event handlers in Docs are a little tricky though. Because docs can handle multiple simultaneous edits by multiple users, the event handlers are handled server-side. The major issue with this structure is that when an event trigger script fails, it fails on the server. If you want to see the debug info you'll need to setup an explicit trigger under the triggers menu that emails you the debug info when the event fails or else it will fail silently.

A simple, easy, hands-on, way to get you out of hot water, especially if you're not so comfortable with git:

1. View the log of your file

   git log myFile.js

   commit 1023057173029091u23f01w276931f7f42595f84f Author: kmiklas Date: Tue Aug 7 09:29:34 2018 -0400

   JIRA-12345 - Refactor with new architecture.

2. Note hash of file:

   1023057173029091u23f01w276931f7f42595f84f

3. Show the file using the hash. Make sure it's what you want:

   git show 1023057173029091u23f01w276931f7f42595f84f:./myFile.js

4. Redirect file to a local copy

   git show 1023057173029091u23f01w276931f7f42595f84f:./myFile.js > myFile.07aug2018.js

5. Back up your current file.

   cp myFile.js myFile.bak.js

6. Open both files in your favorite text editor.

   vim myFile.js
   vim myFile.07aug2018.js

7. Copy n' paste code from myFile.07aug2018.js to myFile.js, and save.

8. Commit and push myFile.js

9. Again view the log, and confirm that your file is properly in place.

10. Tell your clients to pull the latest, happily watch it work with the old version in place.

Not the sexiest, or most git-centric solution, and definitely a "manual" reset/reversion, but it works. It requires minimal knowledge of git, and doesn't disturb the commit history.

This worked for me:

composer require "ext-gd:*" --ignore-platform-reqs

The answers here got me close, but in 2016, I was able to write the following LINQ:

List<ObjectType> objectList = similarTypeList.Select(o =>
    new ObjectType
    {
        PropertyOne = o.PropertyOne,
        PropertyTwo = o.PropertyTwo,
        PropertyThree = o.PropertyThree
    }).ToList();

This is the simple example to use both of them:

import {
  Directive, HostListener, HostBinding
}
from '@angular/core';

@Directive({
  selector: '[Highlight]'
})
export class HighlightDirective {
  @HostListener('mouseenter') mouseover() {
    this.backgroundColor = 'green';
  };

  @HostListener('mouseleave') mouseleave() {
    this.backgroundColor = 'white';
  }

  @HostBinding('style.backgroundColor') get setColor() {
     return this.backgroundColor;
  };

  private backgroundColor = 'white';
  constructor() {}

}

Introduction:

1. HostListener can bind an event to the element.

2. HostBinding can bind a style to the element.

3. this is directive, so we can use it for

   Some Text

4. So according to the debug, we can find that this div has been binded style = "background-color:white"

   Some Text

5. we also can find that EventListener of this div has two event: mouseenter and mouseleave. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.

Try this:

Dim i = Datagridview1.currentrow.index
textbox1.text = datagridview1.item(columnindex, i).value

It should work :)

You need to perform the action from the thread that owns the control.

That's how I'm doing that without adding too much code noise:

control.Invoke(() => textBox1.Text += "hi");

Where Invoke overload is a simple extension from Lokad Shared Libraries:

/// <summary>
/// Invokes the specified <paramref name="action"/> on the thread that owns     
/// the <paramref name="control"/>.</summary>
/// <typeparam name="TControl">type of the control to work with</typeparam>
/// <param name="control">The control to execute action against.</param>
/// <param name="action">The action to on the thread of the control.</param>
public static void Invoke<TControl>(this TControl control, Action action) 
  where TControl : Control
{
  if (!control.InvokeRequired)
  {
    action();
  }
  else
  {
    control.Invoke(action);
  }
}

In case you don't want this changes to be committed at all do git reset --hard.

Next you can checkout to wanted branch, but remember that uncommitted changes will be lost.

you can use getBackStackEntryAt(). In order to know how many entry the activity holds in the backstack you can use getBackStackEntryCount()

int lastFragmentCount = getBackStackEntryCount() - 1;

Just tested it myself and here's how I approached it. Pretty straight forward, let me know if you need any clarification

HTML

<div id="map_canvas" style="width:700px; height:500px; margin-left:80px;" ></div>
<button onclick="displayMap()">Show Map</button>

CSS

<style type="text/css">
#map_canvas {display:none;}
</style>

Javascript

<script>
function displayMap()
{
    document.getElementById( 'map_canvas' ).style.display = "block";
    initialize();
}
function initialize()
{
    // create the map
    var myOptions = {
        zoom: 14,
        center: new google.maps.LatLng( 0.0, 0.0 ),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map( document.getElementById( "map_canvas" ),myOptions );
}
</script>

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

To prevent the browser validation message from appearing in your document, with jQuery:

$('input, select, textarea').on("invalid", function(e) {
    e.preventDefault();
});

I add the region option and everything works then fine for me:

aws ecr get-login --no-include-email --region eu-west-3

NSMutableArray *arrayThatYouCanRemoveObjects = [NSMutableArray arrayWithArray:your_array];

[arrayThatYouCanRemoveObjects removeObjectAtIndex:your_object_index];

[your_array release];

 your_array = [[NSArray arrayWithArray: arrayThatYouCanRemoveObjects] retain];

that's about it

if you dont own your_array(i.e it's autoreleased) remove the release & retain messages

Short answer, you can't.

HTML is used for the page's structure and can't send e-mails, you will need a server side language (such as PHP) to send e-mails, you can also use a third party service and let them handle the e-mail sending for you.

This worked for me with 5 images in diferent sizes.

1. Create a container div
2. An Unordered list for the images
3. On css the unordened must be displayed vertically and without bullets
4. Justify content of container div

This works because of justify-content:space-between, and it's on a list, displayed horizontally.

On CSS

 #container {
            display: flex;
            justify-content: space-between;
 }
    #container ul li{ display:inline; list-style-type:none;
}

On html

<div id="container"> 
  <ul>  
        <li><img src="box1.png"><li>
        <li><img src="box2.png"><li>
        <li><img src="box3.png"><li>
        <li><img src="box4.png"><li>
        <li><img src="box5.png"><li>
    </ul>
</div>

try below query:

DELETE FROM tablename WHERE id < (SELECT * FROM (SELECT (MAX(id)-10) FROM tablename ) AS a)

the inner sub query will return the top 10 value and the outer query will delete all the records except the top 10.

Email address: RFC 2822 Format
Matches a normal email address. Does not check the top-level domain.
Requires the "case insensitive" option to be ON.

[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?

Usage :

bool isEmail = Regex.IsMatch(emailString, @"\A(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)\Z", RegexOptions.IgnoreCase);

The heredoc solutions are certainly the most common way to do this. Other common solutions are:

echo 'line 1, '"${kernel}"'
line 2,
line 3, '"${distro}"'
line 4' > /etc/myconfig.conf

and

exec 3>&1 # Save current stdout
exec > /etc/myconfig.conf
echo line 1, ${kernel}
echo line 2, 
echo line 3, ${distro}
...
exec 1>&3  # Restore stdout

public DateTime DateCreated
{
   get
   {
      return (this.dateCreated == default(DateTime))
         ? this.dateCreated = DateTime.Now
         : this.dateCreated;
   }

   set { this.dateCreated = value; }
}
private DateTime dateCreated = default(DateTime);

Try to use classpath*: prefix instead.

Also please try to deploy exploded war, to ensure that all files are there.

Here's a very simple no-framework wrapper based on the other answers and articles posted in here:

var http = require('http');
var querystring = require('querystring');

function processPost(request, response, callback) {
    var queryData = "";
    if(typeof callback !== 'function') return null;

    if(request.method == 'POST') {
        request.on('data', function(data) {
            queryData += data;
            if(queryData.length > 1e6) {
                queryData = "";
                response.writeHead(413, {'Content-Type': 'text/plain'}).end();
                request.connection.destroy();
            }
        });

        request.on('end', function() {
            request.post = querystring.parse(queryData);
            callback();
        });

    } else {
        response.writeHead(405, {'Content-Type': 'text/plain'});
        response.end();
    }
}

Usage example:

http.createServer(function(request, response) {
    if(request.method == 'POST') {
        processPost(request, response, function() {
            console.log(request.post);
            // Use request.post here

            response.writeHead(200, "OK", {'Content-Type': 'text/plain'});
            response.end();
        });
    } else {
        response.writeHead(200, "OK", {'Content-Type': 'text/plain'});
        response.end();
    }

}).listen(8000);

I faced the same issue and solved using the below steps. Go to Windows->preferences->Editors->File Associations

Here click on Add then type .class click on OK

again click on Add then type .classwithoughtsource click on OK

Now you will be able to see JadClipse option under Java section in Windows->Preferences

Please provide the path of jad.exe file as shown below.

Path for Decompiler-C:\Users\ahr\Documents\eclipse-jee-galileo-SR2-win32\jad.exe Directory for temporary Files-C:\Users\ahr.net.sf.jadclipse

click on Apply

Now you should be able to see the classfiles in proper format.

Hi we can use ToLower Method sometimes it is not filter.

EmployeeId = Session["EmployeeID"].ToString();
var rows = dtCrewList.AsEnumerable().Where
   (row => row.Field<string>("EmployeeId").ToLower()== EmployeeId.ToLower());

   if (rows.Any())
   {
        tblFiltered = rows.CopyToDataTable<DataRow>();
   }

I think the easiest way is using TextBox.SelectAll like in an Enter event:

private void TextBox_Enter(object sender, EventArgs e)
{
    ((TextBox)sender).SelectAll();
}

Try this

AlphaAnimation animation1 = new AlphaAnimation(0.2f, 1.0f);
animation1.setDuration(1000);
animation1.setStartOffset(5000);
animation1.setFillAfter(true);
iv.startAnimation(animation1);

The Servlet Specification JSR-315 clearly defines the web container behavior in the service (and doGet, doPost, doPut etc.) methods (2.3.3.1 Multithreading Issues, Page 9):

A servlet container may send concurrent requests through the service method of the servlet. To handle the requests, the Servlet Developer must make adequate provisions for concurrent processing with multiple threads in the service method.

Although it is not recommended, an alternative for the Developer is to implement the SingleThreadModel interface which requires the container to guarantee that there is only one request thread at a time in the service method. A servlet container may satisfy this requirement by serializing requests on a servlet, or by maintaining a pool of servlet instances. If the servlet is part of a Web application that has been marked as distributable, the container may maintain a pool of servlet instances in each JVM that the application is distributed across.

For servlets not implementing the SingleThreadModel interface, if the service method (or methods such as doGet or doPost which are dispatched to the service method of the HttpServlet abstract class) has been defined with the synchronized keyword, the servlet container cannot use the instance pool approach, but must serialize requests through it. It is strongly recommended that Developers not synchronize the service method (or methods dispatched to it) in these circumstances because of detrimental effects on performance

This is something that keeps coming up -- especially for Google Chrome on Mac OS X Yosemite!

There are numexpr, numba and cython around, the goal of this answer is to take these possibilities into consideration.

But first let's state the obvious: no matter how you map a Python-function onto a numpy-array, it stays a Python function, that means for every evaluation:

• numpy-array element must be converted to a Python-object (e.g. a Float).
• all calculations are done with Python-objects, which means to have the overhead of interpreter, dynamic dispatch and immutable objects.

So which machinery is used to actually loop through the array doesn't play a big role because of the overhead mentioned above - it stays much slower than using numpy's built-in functionality.

Let's take a look at the following example:

# numpy-functionality
def f(x):
    return x+2*x*x+4*x*x*x

# python-function as ufunc
import numpy as np
vf=np.vectorize(f)
vf.__name__="vf"

np.vectorize is picked as a representative of the pure-python function class of approaches. Using perfplot (see code in the appendix of this answer) we get the following running times:

We can see, that the numpy-approach is 10x-100x faster than the pure python version. The decrease of performance for bigger array-sizes is probably because data no longer fits the cache.

It is worth also mentioning, that vectorize also uses a lot of memory, so often memory-usage is the bottle-neck (see related SO-question). Also note, that numpy's documentation on np.vectorize states that it is "provided primarily for convenience, not for performance".

Other tools should be used, when performance is desired, beside writing a C-extension from the scratch, there are following possibilities:

One often hears, that the numpy-performance is as good as it gets, because it is pure C under the hood. Yet there is a lot room for improvement!

The vectorized numpy-version uses a lot of additional memory and memory-accesses. Numexp-library tries to tile the numpy-arrays and thus get a better cache utilization:

# less cache misses than numpy-functionality
import numexpr as ne
def ne_f(x):
    return ne.evaluate("x+2*x*x+4*x*x*x")

Leads to the following comparison:

I cannot explain everything in the plot above: we can see bigger overhead for numexpr-library at the beginning, but because it utilize the cache better it is about 10 time faster for bigger arrays!

Another approach is to jit-compile the function and thus getting a real pure-C UFunc. This is numba's approach:

# runtime generated C-function as ufunc
import numba as nb
@nb.vectorize(target="cpu")
def nb_vf(x):
    return x+2*x*x+4*x*x*x

It is 10 times faster than the original numpy-approach:

However, the task is embarrassingly parallelizable, thus we also could use prange in order to calculate the loop in parallel:

@nb.njit(parallel=True)
def nb_par_jitf(x):
    y=np.empty(x.shape)
    for i in nb.prange(len(x)):
        y[i]=x[i]+2*x[i]*x[i]+4*x[i]*x[i]*x[i]
    return y

As expected, the parallel function is slower for smaller inputs, but faster (almost factor 2) for larger sizes:

While numba specializes on optimizing operations with numpy-arrays, Cython is a more general tool. It is more complicated to extract the same performance as with numba - often it is down to llvm (numba) vs local compiler (gcc/MSVC):

%%cython -c=/openmp -a
import numpy as np
import cython

#single core:
@cython.boundscheck(False) 
@cython.wraparound(False) 
def cy_f(double[::1] x):
    y_out=np.empty(len(x))
    cdef Py_ssize_t i
    cdef double[::1] y=y_out
    for i in range(len(x)):
        y[i] = x[i]+2*x[i]*x[i]+4*x[i]*x[i]*x[i]
    return y_out

#parallel:
from cython.parallel import prange
@cython.boundscheck(False) 
@cython.wraparound(False)  
def cy_par_f(double[::1] x):
    y_out=np.empty(len(x))
    cdef double[::1] y=y_out
    cdef Py_ssize_t i
    cdef Py_ssize_t n = len(x)
    for i in prange(n, nogil=True):
        y[i] = x[i]+2*x[i]*x[i]+4*x[i]*x[i]*x[i]
    return y_out

Cython results in somewhat slower functions:

Conclusion

Obviously, testing only for one function doesn't prove anything. Also one should keep in mind, that for the choosen function-example, the bandwidth of the memory was the bottle neck for sizes larger than 10^5 elements - thus we had the same performance for numba, numexpr and cython in this region.

In the end, the ultimative answer depends on the type of function, hardware, Python-distribution and other factors. For example Anaconda-distribution uses Intel's VML for numpy's functions and thus outperforms numba (unless it uses SVML, see this SO-post) easily for transcendental functions like exp, sin, cos and similar - see e.g. the following SO-post.

Yet from this investigation and from my experience so far, I would state, that numba seems to be the easiest tool with best performance as long as no transcendental functions are involved.

Plotting running times with perfplot-package:

import perfplot
perfplot.show(
    setup=lambda n: np.random.rand(n),
    n_range=[2**k for k in range(0,24)],
    kernels=[
        f, 
        vf,
        ne_f, 
        nb_vf, nb_par_jitf,
        cy_f, cy_par_f,
        ],
    logx=True,
    logy=True,
    xlabel='len(x)'
    )

This should solve your problem: FB Share button/dialog documentation Genereally speaking you can use either normal HTML code and style it with CSS, or you can use Javascript.

Movitz is a Lisp environment written in Common Lisp and running "on the metal". Unfortunately, some links on the Movitz main page deny access, but you can find instructions on how to download and compile the source code from the trac page. Also, a ready image can be found on the archive of this page.

IMHO this is utmost interesting, as it brings back the Lisp machine concept on the currently available hardware. It failed commercially, but this does not prove to me that the idea was bad.

The Unix haters handbook is a fun book that semi-seriously berates the concept of Unix and its derivatives. Many sections argument about how better the Lisp machine concept was.

It's possible that you're not fetching the Joined Set. Be sure to include the set in your HQL:

public List<Node> getAll() {
    Session session = sessionFactory.getCurrentSession();
    Query query = session.createQuery("FROM Node as n LEFT JOIN FETCH n.nodeValues LEFT JOIN FETCH n.nodeStats");
    return  query.list();
}

Where your class has 2 sets like:

public class Node implements Serializable {

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeValue> nodeValues;

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeStat> nodeStats;

}

Below code does the work for converting ms to min:secs with [m:ss] format

int seconds;
int minutes;
String Sec;
long Mills = ...;  // Milliseconds goes here
minutes = (int)(Mills / 1000)  / 60;
seconds = (int)((Mills / 1000) % 60);
Sec = seconds+"";

TextView.setText(minutes+":"+Sec);//Display duration [3:40]

As others have mentioned, the load data local infile works just fine. I tried the php script that Hawkee posted, but didnt work for me. Rather than debug it, here's what i did:

1) copy/paste the header row of the CSV file into a txt file and edit with emacs. add a comma and CR between each field to get each on on it's own line.
2) Save that file as FieldList.txt
3) edit the file to include defns for each field (most were varchar, but quite a few were int(x). Add create table tablename ( to the beginning of the file and ) to the end of the file. Save it as CreateTable.sql
4) start mysql client with input from the Createtable.sql file to create the table
5) start mysql client, copy/paste in most of the 'LOAD DATA INFILE' command subsituting my table name and csv file name. Paste in the FieldList.txt file. Be sure to include the 'IGNORE 1 LINES' before pasting in the field list

Sounds like a lot of work, but easy with emacs.....

ConcurrentLinkedQueue means no locks are taken (i.e. no synchronized(this) or Lock.lock calls). It will use a CAS - Compare and Swap operation during modifications to see if the head/tail node is still the same as when it started. If so, the operation succeeds. If the head/tail node is different, it will spin around and try again.

LinkedBlockingQueue will take a lock before any modification. So your offer calls would block until they get the lock. You can use the offer overload that takes a TimeUnit to say you are only willing to wait X amount of time before abandoning the add (usually good for message type queues where the message is stale after X number of milliseconds).

Fairness means that the Lock implementation will keep the threads ordered. Meaning if Thread A enters and then Thread B enters, Thread A will get the lock first. With no fairness, it is undefined really what happens. It will most likely be the next thread that gets scheduled.

As for which one to use, it depends. I tend to use ConcurrentLinkedQueue because the time it takes my producers to get work to put onto the queue is diverse. I don't have a lot of producers producing at the exact same moment. But the consumer side is more complicated because poll won't go into a nice sleep state. You have to handle that yourself.

You can also use OpenCV's inbuilt functions cv2.hconcat and cv2.vconcat which like their names suggest are used to join images horizontally and vertically respectively.

import cv2

img1 = cv2.imread('opencv/lena.jpg')
img2 = cv2.imread('opencv/baboon.jpg')

v_img = cv2.vconcat([img1, img2])
h_img = cv2.hconcat([img1, img2])

cv2.imshow('Horizontal', h_img)
cv2.imshow('Vertical', v_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Horizontal Concatenation

Vertical Concatenation

Pointing CATALINA_BASE to a different directory from CATALINA_HOME allows you to separate the configuration directory from the binaries directory.

By default, CATALINA_BASE (configurations) and CATALINA_HOME (binaries) point to the same folder, but separating the configurations from the binaries can help you to run multiple instances of Tomcat side by side without duplicating the binaries.

It is also useful when you want to update the binaries, without modifying, or needing to backup/restore your configuration files for Tomcat.

Update 2018

There is an easier way to set CATALINA_BASE now with the makebase utility. I have posted a tutorial that covers this subject at http://blog.rasia.io/blog/how-to-easily-setup-lucee-in-tomcat.html along with a video tutorial at https://youtu.be/nuugoG5c-7M

Original answer continued below

To take advantage of this feature, simply create the config directory and point to it with the CATALINA_BASE environment variable. You will have to put some files in that directory:

• Copy the conf directory from the original Tomcat installation directory, including its contents, and ensure that Tomcat has read permissions to it. Edit the configuration files according to your needs.
• Create a logs directory if conf/logging.properties points to ${catalina.base}/logs, and ensure that Tomcat has read/write permissions to it.
• Create a temp directory if you are not overriding the default of $CATALINA_TMPDIR which points to ${CATALINA_BASE}/temp, and ensure that Tomcat has write permissions to it.
• Create a work directory which defaults to ${CATALINA_BASE}/work, and ensure that Tomcat has write permissions to it.

@PathVariable is used to tell Spring that part of the URI path is a value you want passed to your method. Is this what you want, or are the variables supposed to be form data posted to the URI?

If you want form data, use @RequestParam instead of @PathVariable.

If you want @PathVariable, you need to specify placeholders in the @RequestMapping entry to tell Spring where the path variables fit in the URI. For example, if you want to extract a path variable called contentId, you would use:

@RequestMapping(value = "/whatever/{contentId}", method = RequestMethod.POST)

Edit: Additionally, if your path variable could contain a '.' and you want that part of the data, then you will need to tell Spring to grab everything, not just the stuff before the '.':

@RequestMapping(value = "/whatever/{contentId:.*}", method = RequestMethod.POST)

This is because the default behaviour of Spring is to treat that part of the URL as if it is a file extension, and excludes it from variable extraction.

JavaScript's forEach works a bit different from how one might be used to from other languages for each loops. If reading on the MDN, it says that a function is executed for each of the elements in the array, in ascending order. To continue to the next element, that is, run the next function, you can simply return the current function without having it do any computation.

Adding a return and it will go to the next run of the loop:

var myArr = [1,2,3,4];_x000D_
_x000D_
myArr.forEach(function(elem){_x000D_
  if (elem === 3) {_x000D_
    return;_x000D_
  }_x000D_
_x000D_
  console.log(elem);_x000D_
});

Output: 1, 2, 4

I got the following for me:

formSubmit('#login-form', '/api/user/login', '/members/');

where

function formSubmit(form, url, target) {
    $(form).submit(function(event) {
        $.post(url, $(form).serialize())
            .done(function(res) {
                if (res.success) {
                    window.location = target;
                }
                else {
                    alert(res.error);
                }
            })
            .fail(function(res) {
                alert("Server Error: " + res.status + " " + res.statusText);

            })
        event.preventDefault();
    });
}

This assumes the post to 'url' returns an ajax in the form of {success: false, error:'my Error to display'}

You can vary this as you like. Feel free to use that snippet.

There are severals ways to communicate between activities, fragments, services etc. The obvious one is to communicate using interfaces. However, it is not a productive way to communicate. You have to implement the listeners etc.

My suggestion is to use an event bus. Event bus is a publish/subscribe pattern implementation.

You can subscribe to events in your activity and then you can post that events in your fragments etc.

Here on my blog post you can find more detail about this pattern and also an example project to show the usage.

Your response must return some sort of Response object. You can't just return an object.

So change it to something like:

return Response::json($promotion);

or my favorite using the helper function:

return response()->json($promotion);

If returning a response doesn't work it may be some sort of encoding issue. See this article: The Response content must be a string or object implementing __toString(), \"boolean\" given."

There's a much easier way of doing this. You can assign a Name to your Window or UserControl, and then binding by ElementName.

Window1.xaml

<Window x:Class="QuizBee.Host.Window1"
        x:Name="Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <ListView ItemsSource="{Binding ElementName=Window1, Path=myDictionary}" />
</Window>

Window1.xaml.cs

public partial class Window1:Window
{
    // the property must be public, and it must have a getter & setter
    public Dictionary<string, myClass> myDictionary { get; set; }

    public Window1()
    {
        // define the dictionary items in the constructor
        // do the defining BEFORE the InitializeComponent();

        myDictionary = new Dictionary<string, myClass>()
        {
            {"item 1", new myClass(1)},
            {"item 2", new myClass(2)},
            {"item 3", new myClass(3)},
            {"item 4", new myClass(4)},
            {"item 5", new myClass(5)},
        }; 

        InitializeComponent();
    }
}

Put the values you need someplace where the other script can retrieve them, like a hidden input, and then pull those values from their container when you initialize your new script. You could even put all your params as a JSON string into one hidden field.

It should be (-### is similar to -v):

echo | gcc -### -E - -march=native 

To show the "real" native flags for gcc.

You can make them appear more "clearly" with a command:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )//g'

and you can get rid of flags with -mno-* with:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'

If you are using an <a/> to trigger the report, you can try this approach. Instead of attempting to spawn a new window when window.open() fails, make the default scenario to open a new window via target (and prevent it if window.open() succeeds).

HTML

<a href="http://my/url" target="_blank" id="myLink">Link</a>

JS

var spawn = function (e) {
    try {
        window.open(this.href, "","width=1002,height=700,location=0,menubar=0,scrollbars=1,status=1,resizable=0")
        e.preventDefault(); // Or: return false;
    } catch(e) {
    // Allow the default event handler to take place
    }
}

document.getElementById("myLink").onclick = spawn;

For existing jobs you're editing, the JDK drop-down choice may not be available if you've just added a single JDK config in the 'Configure System' Jenkins settings.

However, it is available for new jobs.

Surprisingly, if you add a second JDK config, it becomes available in an existing job too.

This looks to me like a bug (tested in Jenkins ver. 1.629).

See a similar issue raised here: JDK selection is hidden even when a JDK is configured

Looks like something is wrong with your data, it isn't in the format you are expecting. It could be a new line character or a blank space in the data that is tinkering with your code.

To make things simple, here is how you can get just the one you want:

Simple:

$headerValue = $_SERVER['HTTP_X_REQUESTED_WITH'];

or when you need to get one at a time:

<?php
/**
 * @param $pHeaderKey
 * @return mixed
 */
function get_header( $pHeaderKey )
{
    // Expanded for clarity.
    $headerKey = str_replace('-', '_', $pHeaderKey);
    $headerKey = strtoupper($headerKey);
    $headerValue = NULL;
    // Uncomment the if when you do not want to throw an undefined index error.
    // I leave it out because I like my app to tell me when it can't find something I expect.
    //if ( array_key_exists($headerKey, $_SERVER) ) {
    $headerValue = $_SERVER[ $headerKey ];
    //}
    return $headerValue;
}
// X-Requested-With mainly used to identify Ajax requests. Most JavaScript frameworks
// send this header with value of XMLHttpRequest, so this will not always be present.
$header_x_requested_with = get_header( 'X-Requested-With' );

The other headers are also in the super global array $_SERVER, you can read about how to get at them here: http://php.net/manual/en/reserved.variables.server.php

How do I have to do in Python for calling an static method from another static method of the same class?

Follow these steps to reset password in Windows system

1. Stop Mysql service from task manager

2. Create a text file and paste the below statement

MySQL 5.7.5 and earlier:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yournewpassword');

MySQL 5.7.6 and later:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yournewpassword';

3. Save as mysql-init.txt and place it in 'C' drive.

4. Open command prompt and paste the following

C:\> mysqld --init-file=C:\\mysql-init.txt

I use it like this in asp.net core 3.1

 var url =Request.Scheme+"://"+ Request.Host.Value;

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

The time diff in milliseconds

firstDate.getTime() - secondDate.getTime() 

As Herman pointed out, you can get the index and element from each iteration.

{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}

Working example:

package main

import (
    "html/template"
    "os"
)

type EntetiesClass struct {
    Name string
    Value int32
}

// In the template, we use rangeStruct to turn our struct values
// into a slice we can iterate over
var htmlTemplate = `{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}`

func main() {
    data := map[string][]EntetiesClass{
        "Yoga": {{"Yoga", 15}, {"Yoga", 51}},
        "Pilates": {{"Pilates", 3}, {"Pilates", 6}, {"Pilates", 9}},
    }

    t := template.New("t")
    t, err := t.Parse(htmlTemplate)
    if err != nil {
        panic(err)
    }

    err = t.Execute(os.Stdout, data)
    if err != nil {
        panic(err)
    }

}

Output:

Pilates
3
6
9

Yoga
15
51

@FXML
private void mnuUserLevel_onClick(ActionEvent event) {
    FXMLLoader loader = new FXMLLoader(getClass().getResource("DBedit.fxml"));
    loader.setController(new DBeditEntityUserlevel());

    try {
           Node n = (Node)loader.load();
           AnchorPane.setTopAnchor(n, 0.0);
           AnchorPane.setRightAnchor(n, 0.0);
           AnchorPane.setLeftAnchor(n, 0.0);
           AnchorPane.setBottomAnchor(n, 0.0);
           mainContent.getChildren().setAll(n);
    } catch (IOException e){
           System.out.println(e.getMessage());
    }
}

The scenario is to load a child fxml into parent AnchorPane. To make the child to stretch in accords to its parent use AnChorPane.setxxxAnchor command.

No need to add new plugin in pom.xml. Just run this command

mvn org.codehaus.mojo:exec-maven-plugin:1.5.0:java -Dexec.mainClass="com.example.Main" | grep -Ev '(^\[|Download\w+:)' 

See the maven exec plugin for more usage.

rm -rf some_dir

-r "recursive" -f "force" (suppress confirmation messages)

Be careful!

Try using

git reset --hard <commit id> 

Please Note : Here commit id will the id of the commit you want to go to but not the id you want to reset. this was the only point where i also got stucked.

then push

git push -f <remote> <branch>

Use JQuery, its easy.

Include the JQuery library into your html file in the head as such:

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>

(Make sure that this script tag goes before your other script tags in your html file)

Target your id in your JavaScript file as such:

<script>
var youtubeimcsrc = $('#youtubeimg').attr('src');

//your var will be the src string that you're looking for

</script>

Let us consider table name as tblperson and column name as city. I want to retrieve the most repeated city from the city column:

 select city,count(*) as nor from tblperson
        group by city
          having count(*) =(select max(nor) from 
            (select city,count(*) as nor from tblperson group by city) tblperson)

Here nor is an alias name.

I'd take that a slightly different way if I were you. Change the text link when the page loads, not on the click. I'll give the example in jQuery, but it could easily be done in vanilla javascript (though, jQuery is nicer)

$(function() {
    $('a[href$="url="]')    // all links whose href ends in "url="
        .each(function(i, el) {
            this.href += escape(document.location.href);
        })
    ;
});

and write your HTML like this:

<a href="http://example.com/submit.php?url=">...</a>

the benefits of this are that people can see what they're clicking on (the href is already set), and it removes the javascript from your HTML.

All this said, it looks like you're using PHP... why not add it in server-side?

To make it work I build my directory like this:

Project Public Restrict

So I edited my webconfig for my public folder:

<location path="Project/Public">
    <system.web>
      <authorization>
        <allow users="?"/>
      </authorization>
    </system.web>
  </location>

And for my Restricted folder:

 <location path="Project/Restricted">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorizatio>
    </system.web>
  </location>

See here for the spec of * and ?:

https://docs.microsoft.com/en-us/iis/configuration/system.webserver/security/authorization/add

I hope I have helped.

One additional reason to add final to parameter declarations is that it helps to identify variables that need to be renamed as part of a "Extract Method" refactoring. I have found that adding final to each parameter prior to starting a large method refactoring quickly tells me if there are any issues I need to address before continuing.

However, I generally remove them as superfluous at the end of the refactoring.

An md5 encryption is one of the worst, because you have to turn the code and it is already decrypted. I would recommend you the SHA256. I'm programming a bit longer and have had a good experience. Below would also be an encryption.

password_hash() example using Argon2i

<?php
echo 'Argon2i hash: ' . password_hash('rasmuslerdorf', PASSWORD_ARGON2I);
?>
The above example will output something similar to:

Argon2i hash: $argon2i$v=19$m=1024,t=2,p=2$YzJBSzV4TUhkMzc3d3laeg$zqU/1IN0/AogfP4cmSJI1vc8lpXRW9/S0sYY2i2jHT0

You can use the command PSGetSid from Microsoft's SysInternals team.

Download URL: http://technet.microsoft.com/en-gb/sysinternals/bb897417.aspx

Usage:

psgetsid [\\computer[,computer[,...] | @file] [-u username [-p password]]] [account|SID]
-u  Specifies optional user name for login to remote computer.
-p  Specifies optional password for user name. If you omit this you will be prompted to enter a hidden password.
Account PsGetSid will report the SID for the specified user account rather than the computer.
SID PsGetSid will report the account for the specified SID.
Computer    Direct PsGetSid to perform the command on the remote computer or computers specified. If you omit the computer name PsGetSid runs the command on the local system, and if you specify a wildcard (\\*), PsGetSid runs the command on all computers in the current domain.
@file   PsGetSid will execute the command on each of the computers listed in the file.

Example:

psgetsid S-1-5-21-583907252-682003330-839522115-63941

NB:

• Where the user is a domain/AD(LDAP) user, running this on any computer on the domain should give the same results.
• Where the user is local to the machine the command should either be run on that machine, or you should specify the computer via the optional parameter.

Update

If you use PowerShell, the following may be useful for resolving any AD users listed:

#create a drive for HKEY USERS:
New-PSDrive -PSProvider Registry -Name HKU -Root HKEY_USERS -ErrorAction SilentlyContinue

#List all immediate subfolders
#where they're a folder (not a key)
#and they's an SID (i.e. exclude .DEFAULT and SID_Classes entries)
#return the SID
#and return the related AD entry (should one exist).
Get-ChildItem -Path 'HKU:\' `
| ?{($_.PSIsContainer -eq $true) `
-and ($_.PSChildName -match '^S-[\d-]+$')} `
| select @{N='SID';E={$_.PSChildName}} `
, @{N='Name';E={Get-ADUser $_.PSChildName | select -expand Name}}

You could also refine the SID filter further to only pull back those SIDs which will resolve to an AD account if you wished; more on the SID structure here: https://technet.microsoft.com/en-us/library/cc962011.aspx

Also, the ternary operator expects expressions, not statements. Do not use semicolons, only at the end of the ternary op.

$("#blackbox").css({'background': 
    $("#blackbox").css('background') === 'pink' ? 'black' : 'pink'});

You're right using div.container-fluid and you also need a div.row child. Then, the content must be placed inside without any grid columns. If you have a look at the docs you can find this text:

• Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
• Use rows to create horizontal groups of columns.

Not using grid columns it's ok as stated here:

• Content should be placed within columns, and only columns may be immediate children of rows.

And looking at this example, you can read this text:

Full width, single column: No grid classes are necessary for full-width elements.

Here's a live example showing some elements using the correct layout. This way you don't need any custom CSS or hack.

Actually it can be done in pure css and it's pretty easy...

HTML Code

<label class="filebutton">
Browse For File!
<span><input type="file" id="myfile" name="myfile"></span>
</label>

CSS Styles

label.filebutton {
    width:120px;
    height:40px;
    overflow:hidden;
    position:relative;
    background-color:#ccc;
}

label span input {
    z-index: 999;
    line-height: 0;
    font-size: 50px;
    position: absolute;
    top: -2px;
    left: -700px;
    opacity: 0;
    filter: alpha(opacity = 0);
    -ms-filter: "alpha(opacity=0)";
    cursor: pointer;
    _cursor: hand;
    margin: 0;
    padding:0;
}

The idea is to position the input absolutely inside your label. set the font size of the input to something large, which will increase the size of the "browse" button. It then takes some trial and error using the negative left / top properties to position the input browse button behind your label.

When positioning the button, set the alpha to 1. When you've finished set it back to 0 (so you can see what you're doing!)

Make sure you test across browsers because they'll all render the input button a slightly different size.

Extend HttpServletRequestWrapper, override the header getters to return the parameters as well:

public class AddParamsToHeader extends HttpServletRequestWrapper {
    public AddParamsToHeader(HttpServletRequest request) {
        super(request);
    }

    public String getHeader(String name) {
        String header = super.getHeader(name);
        return (header != null) ? header : super.getParameter(name); // Note: you can't use getParameterValues() here.
    }

    public Enumeration getHeaderNames() {
        List<String> names = Collections.list(super.getHeaderNames());
        names.addAll(Collections.list(super.getParameterNames()));
        return Collections.enumeration(names);
    }
}

..and wrap the original request with it:

chain.doFilter(new AddParamsToHeader((HttpServletRequest) request), response);

That said, I personally find this a bad idea. Rather give it direct access to the parameters or pass the parameters to it.

There are some cases where your rows/LINES and columns do not match the actual size of the "terminal" being used. Perhaps you may not have a "tput" or "stty" available.

Here is a bash function you can use to visually check the size. This will work up to 140 columns x 80 rows. You can adjust the maximums as needed.

function term_size
{
    local i=0 digits='' tens_fmt='' tens_args=()
    for i in {80..8}
    do
        echo $i $(( i - 2 ))
    done
    echo "If columns below wrap, LINES is first number in highest line above,"
    echo "If truncated, LINES is second number."
    for i in {1..14}
    do
        digits="${digits}1234567890"
        tens_fmt="${tens_fmt}%10d"
        tens_args=("${tens_args[@]}" $i)
    done
    printf "$tens_fmt\n" "${tens_args[@]}"
    echo "$digits"
}

Maximum is 2097151, If you try set more error occurred.

You might find a use for the methods method which returns an array of methods for an object. It's not the same as print_r, but still useful at times.

I am using WIN 10, just figure it out for this problem. Type the code below in cmd:

npm config get prefix

and copy&paste the path that you get it from the top into your computer environment variables-->user variables box --> path --> edit -- C:\Program Files\nodejs\node_global, your path may different.

Click Ok and reopen your cmd window, type in ng version, then it works! Cheers!

Here's yet another solution. This uses POSIX substring parameter expansion, so it works in Bash, Dash, KornShell (ksh), Z shell (zsh), etc.

test "${string#*$word}" != "$string" && echo "$word found in $string"

A functionalized version with some examples:

# contains(string, substring)
#
# Returns 0 if the specified string contains the specified substring,
# otherwise returns 1.
contains() {
    string="$1"
    substring="$2"
    if test "${string#*$substring}" != "$string"
    then
        return 0    # $substring is in $string
    else
        return 1    # $substring is not in $string
    fi
}

contains "abcd" "e" || echo "abcd does not contain e"
contains "abcd" "ab" && echo "abcd contains ab"
contains "abcd" "bc" && echo "abcd contains bc"
contains "abcd" "cd" && echo "abcd contains cd"
contains "abcd" "abcd" && echo "abcd contains abcd"
contains "" "" && echo "empty string contains empty string"
contains "a" "" && echo "a contains empty string"
contains "" "a" || echo "empty string does not contain a"
contains "abcd efgh" "cd ef" && echo "abcd efgh contains cd ef"
contains "abcd efgh" " " && echo "abcd efgh contains a space"

Additionally, if you want to use the filter in your controller the same way you do it here:

<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
  {{ item }}
</div>

You could do something like:

var filteredItems =  $scope.$eval('items | filter:filter:criteriaMatch(criteria)');

if you still getting this error try this.

1. Go to Netbeans services
2. Remove Apache Tomcat.
3. Add Apache Tomcat again.
4. Build Project.
5. Deploy Project

Replace [True | False (default)]

Effect

1.  Replace the directive element. 

Dependency:

1. When replace: true, the template or templateUrl must be required. 

As the rule of thumb, NumPy arrays often outperform other solutions while working with POD, Plain Old Data. A string is an example of POD and a character too. To find all the indices of only one char in a string, NumPy ndarrays may be the fastest way:

def find1(str, ch):
  # 0.100 seconds for 1MB str 
  npbuf = np.frombuffer(str, dtype=np.uint8) # Reinterpret str as a char buffer
  return np.where(npbuf == ord(ch))          # Find indices with numpy

def find2(str, ch):
  # 0.920 seconds for 1MB str 
  return [i for i, c in enumerate(str) if c == ch] # Find indices with python

You need to update your virtualbox sw. On new version, there is VBoxDarwinAdditions.pkg included in a additions iso image, in older versions is missing.

As you have already stated in your question you have more than one option. A very basic approach would be using the tag referencing your PHP file in the method attribute. However as esoteric as it may sound AJAX is a more complete approach. Considering that an AJAX call (in combination with jQuery) can be as simple as:

$.post("yourfile.php", {data : "This can be as long as you want"});

And you get a more flexible solution, for example triggering a function after the server request is completed. Hope this helps.

Assuming type TreeMap<String,Integer> :

for(Map.Entry<String,Integer> entry : treeMap.entrySet()) {
  String key = entry.getKey();
  Integer value = entry.getValue();

  System.out.println(key + " => " + value);
}

(key and Value types can be any class of course)

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

SELECT 'DROP TABLE "' || TABLE_NAME || '" CASCADE CONSTRAINTS;' 
FROM user_tables;

user_tables is a system table which contains all the tables of the user the SELECT clause will generate a DROP statement for every table you can run the script

Why are you trying to run "./adb"? That skips the path variable entirely and only looks for "adb" in the current directory. Try running "adb" instead.

Edit: your path looks wrong. You say you get

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Libs/android-sdk-mac_x86/tools:/Libs/android-sdk-mac_x86/platform-tools

You're missing the /Users/simon part.

Also note that if you have both .profile and .bash_profile files, only the latter gets executed.

Here's a jsfiddle with a function call: https://jsfiddle.net/8282emwn/

var marker = new L.Marker([46.947, 7.4448]).on('click', markerOnClick).addTo(map);

function markerOnClick(e)
{
  alert("hi. you clicked the marker at " + e.latlng);
}

Many built-in operations like sum and prod are already able to operate across rows or columns, so you may be able to refactor the function you are applying to take advantage of this.

If that's not a viable option, one way to do it is to collect the rows or columns into cells using mat2cell or num2cell, then use cellfun to operate on the resulting cell array.

As an example, let's say you want to sum the columns of a matrix M. You can do this simply using sum:

M = magic(10);           %# A 10-by-10 matrix
columnSums = sum(M, 1);  %# A 1-by-10 vector of sums for each column

And here is how you would do this using the more complicated num2cell/cellfun option:

M = magic(10);                  %# A 10-by-10 matrix
C = num2cell(M, 1);             %# Collect the columns into cells
columnSums = cellfun(@sum, C);  %# A 1-by-10 vector of sums for each cell

As for someone don't like gray background like academic editor, try this:

p <- p + theme_bw()
p

Below is a very simple VB.NET program that will do what you want.

It will set the buffer to 100 chars wide by 1000 chars high. It then sets the width of the window to match the buffer size.

Module ConsoleBuffer
  Sub Main()
    Console.WindowWidth = 100
    Console.BufferWidth = 100
    Console.BufferHeight = 1000
  End Sub
End Module

UPDATE

I modified the code to first set Console.WindowWidth and then set Console.BufferWidth because if you try to set Console.BufferWidth to a value less than the current Console.WindowWidth the program will throw an exception.

This is only a sample...you should add code to handle command line parameters and error handling.

On modern CMake (>= 3.1) the best way to set global requirements is:

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

It translates to "I want C++11 for all targets, it's not optional, I don’t want to use any GNU or Microsoft extensions." As of C++17, this still is IMHO the best way.

This error occurred for me when I was trying to update the same row from 2 different sessions. I updated a field in one browser while a second was open and had already stored the original object in its session. When I attempted to update from this second "stale" session I get the stale object error. In order to correct this I refetch my object to be updated from the database before I set the value to be updated, then save it as normal.

You can use input text with "list" attribute, which refers to the datalist of values.

<input type="text" name="city" list="cityname">_x000D_
    <datalist id="cityname">_x000D_
      <option value="Boston">_x000D_
      <option value="Cambridge">_x000D_
    </datalist>

This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist

The typical pattern would be as follows, but you need to actually define how the ordering should be applied (since a table is, by definition, an unordered bag of rows):

SELECT t.A, t.B, t.C, number = ROW_NUMBER() OVER (ORDER BY t.A)
  FROM dbo.tableZ AS t
  ORDER BY t.A;

Not sure what the variables in your question are supposed to represent (they don't match).

If it is not Oracle's Java, you may not be able to tell. When I install Oracle Java 64-bit, the files go into C:\Program Files\Java, but when I install a 32-bit version, they default to C:\Program Files (x86)\Java instead. Of course, the person who installed Java could have overridden those defaults.

Here is my solution:

public long GetTime()
{
    DateTime dtCurTime = DateTime.Now.ToUniversalTime();

    DateTime dtEpochStartTime = Convert.ToDateTime("1/1/1970 0:00:00 AM");

    TimeSpan ts = dtCurTime.Subtract(dtEpochStartTime);

    double epochtime;

    epochtime = ((((((ts.Days * 24) + ts.Hours) * 60) + ts.Minutes) * 60) + ts.Seconds);   

    return Convert.ToInt64(epochtime);
}

Better

if ! wget -q --spider --tries=10 --timeout=20 google.com
then
  echo 'Sorry you are Offline'
  exit 1
fi

You have "runs on actual browser" as a pro, but in my experience that is a con because it is slow. But what makes it valuable is the lack of sufficient JS emulation from the non-browser alternatives. It could be that if your JS is complex enough that only an in browser test will suffice, but there are a couple more options to consider:

HtmlUnit: "It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use." If its emulation is good enough for your use then it will be much faster than driving a browser.

But maybe HtmlUnit has good enough JS support but you don't like Java? Then maybe:

Celerity: Watir API running on JRuby backed by HtmlUnit.

or similarly

Schnell: another JRuby wrapper of HtmlUnit.

Of course if HtmlUnit isn't good enough and you have to drive a browser then you might consider Watir to drive your JS.

Just set using JS as follows:

<script>
    var vid = document.getElementById("myVideo");
    vid.autoplay = false;
    vid.load();
</script>

Set true to turn on autoplay. Set false to turn off autoplay.

Try to use this , it works perfectly for me

  // 

   varb = new List<object>();

 // Example 

   varb.Add(new[] { float.Parse(GridView1.Rows[1].Cells[2].Text )});

 // JSON  + Serializ

public string Json()
        {  
            return (new JavaScriptSerializer()).Serialize(varb);
        }


//  Jquery SIDE 

  var datasets = {
            "Products": {
                label: "Products",
                data: <%= getJson() %> 
            }

For builtin JS types you can use:

function getTypeName(val) {
    return {}.toString.call(val).slice(8, -1);
}

Here we use 'toString' method from 'Object' class which works different than the same method of another types.

Examples:

// Primitives
getTypeName(42);        // "Number"
getTypeName("hi");      // "String"
getTypeName(true);      // "Boolean"
getTypeName(Symbol('s'))// "Symbol"
getTypeName(null);      // "Null"
getTypeName(undefined); // "Undefined"

// Non-primitives
getTypeName({});            // "Object"
getTypeName([]);            // "Array"
getTypeName(new Date);      // "Date"
getTypeName(function() {}); // "Function"
getTypeName(/a/);           // "RegExp"
getTypeName(new Error);     // "Error"

If you need a class name you can use:

instance.constructor.name

Examples:

({}).constructor.name       // "Object"
[].constructor.name         // "Array"
(new Date).constructor.name // "Date"

function MyClass() {}
let my = new MyClass();
my.constructor.name         // "MyClass"

But this feature was added in ES2015.

You can use Javascript to dynamically set the height to 100% of the window and then center it using a negative left margin based on the ratio of video width to window width.

http://jsfiddle.net/RfV5C/

var $video  = $('video'),
    $window = $(window); 

$(window).resize(function(){
    var height = $window.height();
    $video.css('height', height);

    var videoWidth = $video.width(),
        windowWidth = $window.width(),
    marginLeftAdjust =   (windowWidth - videoWidth) / 2;

    $video.css({
        'height': height, 
        'marginLeft' : marginLeftAdjust
    });
}).resize();

If you are looking for a way to import all your images from the image

// Import all images in image folder
function importAll(r) {
    let images = {};
    r.keys().map((item, index) => { images[item.replace('./', '')] = r(item); });
    return images;
}

const images = importAll(require.context('../images', false, /\.(gif|jpe?g|svg)$/));

Then:

<img src={images['image-01.jpg']}/>

An alternative solution to that of @Aaron is the bquote() function. We need to supply a valid R expression, in this case LABEL ~ x^2 for example, where LABEL is the string you want to assign from the vector labNames. bquote evaluates R code within the expression wrapped in .( ) and subsitutes the result into the expression.

Here is an example:

labNames <- c('xLab','yLab')
xlab <- bquote(.(labNames[1]) ~ x^2)
ylab <- bquote(.(labNames[2]) ~ y^2)
plot(c(1:10), xlab = xlab, ylab = ylab)

(Note the ~ just adds a bit of spacing, if you don't want the space, replace it with * and the two parts of the expression will be juxtaposed.)

i had the same problem with more than 250 lines and here is how i did it:

for example :

<row id="1" />
<row id="1" />
<row id="1" />
<row id="1" />
<row id="1" />

you put the cursor just after the "1" and you click on alt + shift and start descending with down arrow until your reach the bottom line now you see a group of selections click on erase to erase the number 1 on each line simultaneously and go to Edit -> Column Editor and select Number to Insert then put 1 in initial number field and 1 in incremented by field and check zero numbers and click ok

Congratulations you did it :)

Methods suggest something has to happen to return the value, properties suggest that the value is already there. This is a rule of thumb, sometimes you might want a property that does a little work (i.e. Count), but generally it's a useful way to decide.

If you are using Git GUI, first fetch then merge.

Fetch via Remote menu >> Fetch >> Origin. Merge via Merge menu >> Merge Local.

The following dialog appears.

Select the tracking branch radio button (also by default selected), leave the yellow box empty and press merge and this should update the files.

I had already reverted some local changes before doing these steps since I wanted to discard those anyways so I don't have to eliminate via merge later.

~ FOR VISUAL STUDIO 6 ~

use: ctrl+shift+8 to toggle on/off.

(or manualy go to: Edit> Advance > "View Whitespaces")

goodluck!

Works also for Visual Studio 2008, when Tools/Options/Environment/Keyboard/Mapping Scheme: Visual C++ 6 is selected.

You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5. The custom formula should be =IF($B$5="X", TRUE, FALSE), shown in the example below.

Use FUNCTION:

CREATE OR REPLACE FUNCTION test_function
RETURN VARCHAR2 IS

BEGIN
  RETURN 'This is being returned from a function';
END test_function;

It should be:

document.getElementById("placehere").appendChild(elem);

And place your div before your javascript, because if you don't, the javascript executes before the div exists. Or wait for it to load. So your code looks like this:

<html>

<body>
<script type="text/javascript">
window.onload=function(){
var elem = document.createElement("img");
elem.setAttribute("src", "http://img.zohostatic.com/discussions/v1/images/defaultPhoto.png");
elem.setAttribute("height", "768");
elem.setAttribute("width", "1024");
elem.setAttribute("alt", "Flower");
document.getElementById("placehere").appendChild(elem);
}
</script>
<div id="placehere">

</div>

</body>
</html>

To prove my point, see this with the onload and this without the onload. Fire up the console and you'll find an error stating that the div doesn't exist or cannot find appendChild method of null.

Some thing like this should also work

import numpy as np    

def proper_round(a):
    '''
    given any real number 'a' returns an integer closest to 'a'
    '''
    a_ceil = np.ceil(a)
    a_floor = np.floor(a)
    if np.abs(a_ceil - a) < np.abs(a_floor - a):
        return int(a_ceil)
    else:
        return int(a_floor)

You can get a more detailed list (e.g. structured by defining class) with gems like debugging or looksee.

You can do it this way:

@Html.EditorFor(m => m.userName, new { htmlAttributes = new { disabled = true } })

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

The RemoveAll method should do the trick:

parameterList.RemoveAll(delegate (object o) { return o == null; });
