Do you have a bean declared in your context file that has an id of "articleService"? I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire.

I also need this feature on Firebug! Until then, another approach is to use this online service to remove classes and convert the css to inline styles.

Click services on the Xampp control panel (filename is services.msc, extra info).

First, look for IIS, if it is running. Stop it (stop this service option on the left after clicking on the service name.). Then, this is the main problem, Look for Web deployment Service (not the exact name though it has Web deployment at the beginning.). Stop this service too. Try again and Apache should work.

If you are running Skype, exit out of that too, run Apache, then launch Skype

Which version of SQL Server?

For SQL Server 2005 and later, you can obtain the SQL script used to create the view like this:

select definition
from sys.objects     o
join sys.sql_modules m on m.object_id = o.object_id
where o.object_id = object_id( 'dbo.MyView')
  and o.type      = 'V'

This returns a single row containing the script used to create/alter the view.

Other columns in the table tell about about options in place at the time the view was compiled.

Caveats

• If the view was last modified with ALTER VIEW, then the script will be an ALTER VIEW statement rather than a CREATE VIEW statement.

• The script reflects the name as it was created. The only time it gets updated is if you execute ALTER VIEW, or drop and recreate the view with CREATE VIEW. If the view has been renamed (e.g., via sp_rename) or ownership has been transferred to a different schema, the script you get back will reflect the original CREATE/ALTER VIEW statement: it will not reflect the objects current name.

• Some tools truncate the output. For example, the MS-SQL command line tool sqlcmd.exe truncates the data at 255 chars. You can pass the parameter -y N to get the result with N chars.

The equivalent in a more modern and browser compatible way, using modern addEventListener APIs.

window.addEventListener('beforeunload', (event) => {
  // Cancel the event as stated by the standard.
  event.preventDefault();
  // Chrome requires returnValue to be set.
  event.returnValue = '';
});

It doesn't when you start a long operation behind, because everything STOPS since you'Re in the same thread.

Just for someone looking for a solution more similar to R:

df[(df.Product == p_id) & (df.Time> start_time) & (df.Time < end_time)][['Time','Product']]

No need for data.loc or query, but I do think it is a bit long.

Initialize DataTable:

DataTable dt = new DataTable(); 
dt.Columns.Add("id", typeof(String)); 
dt.Columns.Add("name", typeof(String)); 
for (int i = 0; i < 5; i++)
{
    string index = i.ToString();
    dt.Rows.Add(new object[] { index, "name" + index });
}

Query itself:

IList<Class1> items = dt.AsEnumerable().Select(row => 
    new Class1
        {
            id = row.Field<string>("id"),
            name = row.Field<string>("name")
        }).ToList();

Just because no-one else has posted this opinion, I would say

avoid else clauses in try/excepts because they're unfamiliar to most people

Unlike the keywords try, except, and finally, the meaning of the else clause isn't self-evident; it's less readable. Because it's not used very often, it'll cause people that read your code to want to double-check the docs to be sure they understand what's going on.

(I'm writing this answer precisely because I found a try/except/else in my codebase and it caused a wtf moment and forced me to do some googling).

So, wherever I see code like the OP example:

try:
    try_this(whatever)
except SomeException as the_exception:
    handle(the_exception)
else:
    # do some more processing in non-exception case
    return something

I would prefer to refactor to

try:
    try_this(whatever)
except SomeException as the_exception:
    handle(the_exception)
    return  # <1>
# do some more processing in non-exception case  <2>
return something

• <1> explicit return, clearly shows that, in the exception case, we are finished working

• <2> as a nice minor side-effect, the code that used to be in the else block is dedented by one level.

I got same issue. I was getting the System.Data.Entity.Infrastructure; error which is only part of v5.0 or later. Just right click the Reference and select "Manage NuGet Package" . In the Installed Package option , uninstall the Entity FrameWork which is already installed and Install the 5.0 version. It solve the problem. I was trying manually get the System.Data.Entity reference , which was not success.

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

For EF 6 here's a one-liner if you're re-scaffolding a lot in development. Just update the vars and then keep using the up arrow in package manager console to rinse and repeat.

$lastGoodTarget = "OldTargetName"; $newTarget = "NewTargetName"; Update-Database -TargetMigration "$lastGoodTarget" -Verbose; Add-Migration "$newTarget" -Verbose -Force

Why is this necessary you ask? Not sure which versions of EF6 this applies but if your new migration target has already been applied then using '-Force' to re-scaffold in Add-Migration will not actually re-scaffold, but instead make a new file (this is a good thing though because you wouldn't want to lose your 'Down'). The above snippet does the 'Down' first if necessary then -Force works properly to re-scaffold.

If you run the command cmd, it will update all system variables for that command window.

I hope this one might help you.

let data = [];
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };

let tempData = [];

tempData= data.filter((item)=>item.Status!='Invalid')

console.log(tempData)

It doesn't really matter. "".equals(str) is more clear in my opinion.

isEmpty() returns count == 0;

Nodejs supports async/await from version 7.6.

Release post: https://v8project.blogspot.com.br/2016/10/v8-release-55.html

Here is a one liner, to do it. You simply concatenate the two string in each of the column with a " " space in between.

Say df is your dataframe and columns are 'Time' and 'Date'. And your new column is DateAndTime.

df['DateAndTime'] = df['Date'].str.cat(df['Time'],sep=" ")

And if you also wanna handle entries like datetime objects, you can do this. You can tweak the formatting as per your needs.

df['DateAndTime'] = pd.to_datetime(df['DateAndTime'], format="%m/%d/%Y %I:%M:%S %p")

Cheers!! Happy Data Crunching.

Like this:

Dim rng as Range
Set rng = ActiveCell.Resize(numRows, numCols)

then read the contents of that range to an array:

Dim arr As Variant
arr = rng.Value
'arr is now a two-dimensional array of size (numRows, numCols)

or, select the range (I don't think that's what you really want, but you ask for this in the question).

rng.Select

While its true that git commits don't have a specific field called "username", a git repo does have users, and the users do have names. ;) If what you want is the github username, then knittl's answer is right. But since your question asked about git cli and not github, here's how you get a git user's email address using the command line:

To see a list of all users in a git repo using the git cli:

git log --format="%an %ae" | sort | uniq

To search for a specific user by name, e.g., "John":

git log --format="%an %ae" | sort | uniq | grep -i john

Here are few pointers/suggestions for investigation

1. I see that every time you vote, you call vote method which creates a fresh HTTP connection.
2. This might be a problem. I would suggest to use a single HttpClient instance to post to the server. This way it wont create too many connections from the client side.
3. At the end of everything, HttpClient needs to be shut and hence call httpclient.getConnectionManager().shutdown(); to release the resources used by the connections.

1. click on three dots in the top right ->
2. click on "Undock into separate window" icon

I was running Vagrant with VirtualBox 5.1.X, and had to downgrade to VirtualBox 5.0.40, and install the vbguest plugin to solve this problem.

My steps were:

• Uninstall VirtualBox 5.1.X
• Install Vagrant 5.0.40
• Reboot my machine
• Run vagrant up for my vagrant. It'll fail.
• Run vagrant plugin install vagrant-vbguest while my VM is running, to install the vagrant plugin. This manages syncing VirtualBox Guest versions between host and guest.
• Run vagrant reload to reload my virtual machine
• Magic!

As mentioned by phihag in his answer,

b = a[:]

will work for your case since slicing a list creates a new memory id of the list (meaning you are no longer referencing the same object in your memory and the changes you make to one will not be reflected in the other.)

However, there is a slight problem. If your list is multidimensional, as in lists within lists, simply slicing will not solve this problem. Changes made in the higher dimensions, i.e. the lists within the original list, will be shared between the two.

Do not fret, there is a solution. The module copy has a nifty copying technique that takes care of this issue.

from copy import deepcopy

b = deepcopy(a)

will copy a list with a new memory id no matter how many levels of lists it contains!

Since your server already includes the sites-enabled folder ( notice the include /etc/nginx/sites-enabled/* line ), then you better use that.

1. Create a file inside /etc/nginx/sites-available and call it whatever you want, I'll call it django since it's a djanog server

   sudo touch /etc/nginx/sites-available/django
   

2. Then create a symlink that points to it

   sudo ln -s /etc/nginx/sites-available/django /etc/nginx/sites-enabled
   

3. Then edit that file with whatever file editor you use, vim or nano or whatever and create the server inside it

   server {
       # hostname or ip or multiple separated by spaces
       server_name localhost example.com 192.168.1.1; #change to your setting
       location / {
           root /home/techcee/scrapbook/local/lib/python2.7/site-packages/django/__init__.pyc/;
       }
   }
   

4. Restart or reload nginx settings

   sudo service nginx reload
   

Note I believe that your configuration like this probably won't work yet because you need to pass it to a fastcgi server or something, but at least this is how you could create a valid server

Some Linux based MySQL installations require case sensitive. Work around is to apply nativeQuery.

@Query(value = 'select ID, CLUMN2, CLUMN3 FROM VENDOR c where c.ID = :ID', nativeQuery = true)

Use Below Code

$('input[name=your_radio_button_name]:checked').val();

Please note, value attribute should be defined so could get "Male" or "Female" in your result.

<div id='div_container'>
<input type="radio" name="Gender" value="Male" /> Male <br />
<input type="radio" name="Gender" value="Female" /> Female
</div>

I just changed project facet to 1.7 and it worked.

It sounds like you're confused between pointers and arrays. Pointers and arrays (in this case char * and char []) are not the same thing.

• An array char a[SIZE] says that the value at the location of a is an array of length SIZE
• A pointer char *a; says that the value at the location of a is a pointer to a char. This can be combined with pointer arithmetic to behave like an array (eg, a[10] is 10 entries past wherever a points)

In memory, it looks like this (example taken from the FAQ):

 char a[] = "hello";  // array

   +---+---+---+---+---+---+
a: | h | e | l | l | o |\0 |
   +---+---+---+---+---+---+

 char *p = "world"; // pointer

   +-----+     +---+---+---+---+---+---+
p: |  *======> | w | o | r | l | d |\0 |
   +-----+     +---+---+---+---+---+---+

It's easy to be confused about the difference between pointers and arrays, because in many cases, an array reference "decays" to a pointer to it's first element. This means that in many cases (such as when passed to a function call) arrays become pointers. If you'd like to know more, this section of the C FAQ describes the differences in detail.

One major practical difference is that the compiler knows how long an array is. Using the examples above:

char a[] = "hello";  
char *p =  "world";  

sizeof(a); // 6 - one byte for each character in the string,
           // one for the '\0' terminator
sizeof(p); // whatever the size of the pointer is
           // probably 4 or 8 on most machines (depending on whether it's a 
           // 32 or 64 bit machine)

Without seeing your code, it's hard to recommend the best course of action, but I suspect changing to use pointers everywhere will solve the problems you're currently having. Take note that now:

• You will need to initialise memory wherever the arrays used to be. Eg, char a[10]; will become char *a = malloc(10 * sizeof(char));, followed by a check that a != NULL. Note that you don't actually need to say sizeof(char) in this case, because sizeof(char) is defined to be 1. I left it in for completeness.

• Anywhere you previously had sizeof(a) for array length will need to be replaced by the length of the memory you allocated (if you're using strings, you could use strlen(), which counts up to the '\0').

• You will need a make a corresponding call to free() for each call to malloc(). This tells the computer you are done using the memory you asked for with malloc(). If your pointer is a, just write free(a); at a point in the code where you know you no longer need whatever a points to.

As another answer pointed out, if you want to get the address of the start of an array, you can use:

char* p = &a[0] 

You can read this as "char pointer p becomes the address of element [0] of a".

A trick:

Use MAMPPRO and create: server name: the EXACT adress of you website (eg: helloworld.com) to your site on your disk

On Facebook: So you can keep your original Site URL as well (eg: helloworld.com)

Now you understand that when you type your website on the adress bar you are in local! ..and when you want to be online, just inactive the server on MAMP PRO..

:)

Heredoc may be an option, see example 2 here: http://php.net/manual/en/language.types.string.php

For Chrome via Chrome Fullscreen API

Note that for (Chrome) security reasons it cannot be called or executed automatically, there must be an interaction from the user first. (Such as button click, keydown/keypress etc.)

addEventListener("click", function() {
    var
          el = document.documentElement
        , rfs =
               el.requestFullScreen
            || el.webkitRequestFullScreen
            || el.mozRequestFullScreen
    ;
    rfs.call(el);
});

Javascript Fullscreen API as demo'd by David Walsh that seems to be a cross browser solution

// Find the right method, call on correct element
function launchFullScreen(element) {
  if(element.requestFullScreen) {
    element.requestFullScreen();
  } else if(element.mozRequestFullScreen) {
    element.mozRequestFullScreen();
  } else if(element.webkitRequestFullScreen) {
    element.webkitRequestFullScreen();
  }
}

// Launch fullscreen for browsers that support it!
launchFullScreen(document.documentElement); // the whole page
launchFullScreen(document.getElementById("videoElement")); // any individual element

In your cmd type command python manage.py findstatic --verbosity 2 static It will give the directory in which Django is looking for static files.If you have created a virtual environment then there will be a static folder inside this virtual_environment_name folder. VIRTUAL_ENVIRONMENT_NAME\Lib\site-packages\django\contrib\admin\static. On running the above 'findstatic' command if Django shows you this path then just paste all your static files in this static directory. In your html file use JINJA syntax for href and check for other inline css. If still there is an image src or url after giving JINJA syntax then prepend it with '/static'. This worked for me.

(updated on 3-29-2019 to use the https instead of ssh, so you don't need to use ssh keys)

It seems like for BitBucket, you do have to create a repo online first. Using the instructions from Atlassian, simply create a new BitBucket repository, copy the repository url to the clipboard, and then add that repository as a new remote to your local repository (full steps below):

Get Repo URL

1. in your BitBucket repo, choose "Clone" on the top-right
2. choose "HTTPS" instead of "SSH" in the top-right of the dialog
3. it should show your repo url in the form git clone <repository url>

Add Remote Using CLI

1. cd /path/to/my/repo
2. git remote add origin https://bitbucket.org/<username>/<reponame>.git
3. git push -u origin --all

Add Remote Using SourceTree

1. Repository>Add Remote...
2. Paste the BitBucket repository url (https://bitbucket.org/<username>/<reponame>.git)

Old Method: Creating & Registering SSH Keys

(this method is if you use the ssh url instead of the https url, which looks like ssh://[email protected]/<username>/<reponame>.git. I recommend just using https)

BitBucket is great for private repos, but you'll need to set up an ssh key to authorize your computer to work with your BitBucket account. Luckily Sourcetree makes it relatively simple:

Creating a Key In SourceTree:

1. In Tools>Options, make sure SSH Client: is set to PuTTY/Plink under the General tab
2. Select Tools>Create or Import SSH Keys
3. In the popup window, click Generate and move your mouse around to give randomness to the key generator

4. You should get something like whats shown in the screenshot below. Copy the public key (highlighted in blue) to your clipboard

   

5. Click Save private Key and Save public key to save your keys to wherever you choose (e.g. to <Home Dir>/putty/ssk-key.ppk and <Home Dir>/putty/ssh-key.pub respectively) before moving on to the next section

Registering The Key In BitBucket

1. Log in to your BitBucket account, and on the top right, click your profile picture and click Settings
2. Go to the SSH Keys tab on the left sidebar
3. Click Add SSH Key, give it a name, and paste the public key you copied in step 4 of the previous section

That's it! You should now be able to push/pull to your BitBucket private repos. Your keys aren't just for Git either, many services use ssh keys to identify users, and the best part is you only need one. If you ever lose your keys (e.g. when changing computers), just follow the steps to create and register a new one.

scp -i ~/.ssh/key.pem ec2-user@ip:/home/ec2-user/file-to-copy.txt .

The file name shouldnt be between the pem file and the ec2-user string - that doesnt work. This also allows you to reserve the name of the copied file.

expanding on @malenkiy_scot's answer. I created a new jenkins job to build up the file that is used by Extended Choice Plugin.

you can do the following (I did it as execute shell steps in jenkins, but you could do it in a script):

git ls-remote [email protected]:my/repo.git |grep refs/heads/* >tmp.txt
sed -e 's/.*refs\/heads\///' tmp.txt > tmp2.txt
tr '\n' ',' < tmp2.txt > tmp3.txt
sed '1i\branches=' tmp3.txt > tmp4.txt
tr -d '\n'  < tmp4.txt > branches.txt

I then use the Artifact deployer plugin to push that file to a shared location, which is in a web url, then just use 'http://localhost/branches.txt' in the Extended Choice plugin as the url. works like a charm.

I found an answer that I like much better here

Looks like this:

$(document).ready(function(){
    $("a").click(function () { 
        $(this).fadeTo("fast", .5).removeAttr("href"); 
    });
});

Enabling would involve setting the href attribute

$(document).ready(function(){
    $("a").click(function () { 
        $(this).fadeIn("fast").attr("href", "http://whatever.com/wherever.html"); 
    });
});

This gives you the appearance that the anchor element becomes normal text, and vice versa.

An example PUT following Martin C. Martin's comment:

curl -T filename.txt http://www.example.com/dir/

With -T (same as --upload-file) curl will use PUT for HTTP.

  InputStream imageStream = null;
    try {
        imageStream = getContext().getContentResolver().openInputStream(uri);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);

Below is the code for pass unique notification id:

//"CommonUtilities.getValudeFromOreference" is the method created by me to get value from savedPreferences.
String notificationId = CommonUtilities.getValueFromPreference(context, Global.NOTIFICATION_ID, "0");
int notificationIdinInt = Integer.parseInt(notificationId);

notificationManager.notify(notificationIdinInt, notification);

// will increment notification id for uniqueness
notificationIdinInt = notificationIdinInt + 1;
CommonUtilities.saveValueToPreference(context, Global.NOTIFICATION_ID, notificationIdinInt + "");
//Above "CommonUtilities.saveValueToPreference" is the method created by me to save new value in savePreferences.

Reset notificationId in savedPreferences at specific range like I have did it at 1000. So it will not create any issues in future. Let me know if you need more detail information or any query. :)

I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,            "http://url/url/url" );

This is a rehash of the previous answer but it's more likely to work on different mongodb versions.

db.collection.find().limit(1).sort({$natural:-1})

To add to Jason's answer:

You can speed the process up (which might be helpful for very large exponents) using the binary expansion of the exponent. First calculate 5, 5^2, 5^4, 5^8 mod 221 - you do this by repeated squaring:

 5^1 = 5(mod 221)
 5^2 = 5^2 (mod 221) = 25(mod 221)
 5^4 = (5^2)^2 = 25^2(mod 221) = 625 (mod 221) = 183(mod221)
 5^8 = (5^4)^2 = 183^2(mod 221) = 33489 (mod 221) = 118(mod 221)
5^16 = (5^8)^2 = 118^2(mod 221) = 13924 (mod 221) = 1(mod 221)
5^32 = (5^16)^2 = 1^2(mod 221) = 1(mod 221)

Now we can write

55 = 1 + 2 + 4 + 16 + 32

so 5^55 = 5^1 * 5^2 * 5^4 * 5^16 * 5^32 
        = 5   * 25  * 625 * 1    * 1 (mod 221)
        = 125 * 625 (mod 221)
        = 125 * 183 (mod 183) - because 625 = 183 (mod 221)
        = 22875 ( mod 221)
        = 112 (mod 221)

You can see how for very large exponents this will be much faster (I believe it's log as opposed to linear in b, but not certain.)

I needed to do the same thing and this is the solution I found:

1. Enable logging from the command line using the flags:

   --enable-logging --v=1

   This logs everything Chrome does internally, but it also logs all the console.log() messages as well. The log file is called chrome_debug.log and is located in the User Data Directory.

2. Filter the log file you get for lines with CONSOLE(\d+).

Note that console logs do not appear with --incognito.

In case you just need to remove the duplicates using only ArrayList, no other Collection classes, then:-

//list is the original arraylist containing the duplicates as well
List<String> uniqueList = new ArrayList<String>();
    for(int i=0;i<list.size();i++) {
        if(!uniqueList.contains(list.get(i)))
            uniqueList.add(list.get(i));
    }

Hope this helps!

Firstly,Object is created and then we assign it 's address to pointers.Constructors are called at the time of object creation and used to initializ the value of data members. Pointer to object comes into scenario after object creation. Thats why, C++ do not allows us to make constructors as virtual . .another reason is that, There is nothing like pointer to constructor , which can point to virtual constructor,because one of the property of virtual function is that it can be used by pointers only.

2. Virtual functions are used to assign value dynamically,as constructors are static,so we can not make them virtual.

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

Unless you have a specific need for a dynamically compiled project, don't use a web site project.

Why? Because web site project will drive you up the wall when trying to change or understand your project. The static typing find features (e.g. find usages, refactor) in Visual Studio will all take forever on any reasonably sized project. For further information, see the Stack Overflow question Slow “Find All References” in Visual Studio.

I really can't see why they dropped web applications in Visual Studio 2005 for the pain-inducing, sanity-draining, productivity carbuncle web site project type.

An another way is simply :

if($test){
    echo "Yes 1";
}
if(!is_null($test)){
    echo "Yes 2";
}

$test = "hello";

if($test){
    echo "Yes 3";
}

Will return :

"Yes 3"

The best way is to use isset(), otherwise you can have an error like "undefined $test".

You can do it like this :

if( isset($test) && ($test!==null) )

You'll not have any error because the first condition isn't accepted.

Another non-allocating alternative: create a singleton, say of class C, as you need it:

singleton<C>()

using

template <class X>
X& singleton()
{
    static X x;
    return x;
}

Neither this nor Catalin's answer is automatically thread-safe in current C++, but will be in C++0x.

If you want all groups known to the system, I would recommend using getent group instead of parsing /etc/group:

getent group

The reason is that on networked systems, groups may not only read from /etc/group file, but also obtained through LDAP or Yellow Pages (the list of known groups comes from the local group file plus groups received via LDAP or YP in these cases).

If you want just the group names you can use:

getent group | cut -d: -f1

A backslash needs to be escaped with another backslash.

print('\\')

#map {
  float: right;
  width: 700px;
  height: 500px;
}
#list {
  float:left;
  width:200px;
  background: #eee;
  list-style: none;
  padding: 0;
}
#similar {
  float: left;
  clear: left;
  width: 200px;
  background: #000;
}

Using lapply family and anonymous function approach you may:

1. Try to attach all listed packages.
2. Install missing only (using || lazy evaluation).
3. Attempt to attach again those were missing in step 1 and installed in step 2.

4. Print each package final load status (TRUE / FALSE).

   req <- substitute(require(x, character.only = TRUE))
   lbs <- c("plyr", "psych", "tm")
   sapply(lbs, function(x) eval(req) || {install.packages(x); eval(req)})
   
   plyr psych    tm 
   TRUE  TRUE  TRUE 
   

To start/stop the animation, you should do this:

To start:

progressBar1.Style = ProgressBarStyle.Marquee;
progressBar1.MarqueeAnimationSpeed = 30;

To stop:

progressBar1.Style = ProgressBarStyle.Continuous;
progressBar1.MarqueeAnimationSpeed = 0;

Neither, because both are quite verbose for a very simple task. You can just do:

let result = ({
  1: 'One',
  2: 'Two',
  3: 'Three'
})[opt] ?? 'Default'    // opt can be 1, 2, 3 or anything (default)

This, of course, also works with strings, a mix of both or without a default case:

let result = ({
  'first': 'One',
  'second': 'Two',
  3: 'Three'
})[opt]                // opt can be 'first', 'second' or 3

Explanation:

It works by creating an object where the options/cases are the keys and the results are the values. By putting the option into the brackets you access the value of the key that matches the expression via the bracket notation.

This returns undefined if the expression inside the brackets is not a valid key. We can detect this undefined-case by using the nullish coalescing operator ?? and return a default value.

Example:

console.log('Using a valid case:', ({
  1: 'One',
  2: 'Two',
  3: 'Three'
})[1] ?? 'Default')

console.log('Using an invalid case/defaulting:', ({
  1: 'One',
  2: 'Two',
  3: 'Three'
})[7] ?? 'Default')

.as-console-wrapper {max-height: 100% !important;top: 0;}

I assume:

• you want to write 100% valid HTML5
• you want to place the code snippet (almost) literal in the HTML
  • especially < should not need escaping

All your options are in this tree:

• with HTML syntax
  • there are five kinds of elements
  • those called "normal elements" (like <p>)
    • can't have a literal <
    • it would be considered the start of the next tag or comment
  • void elements
    • they have no content
    • you could put your HTML in a data attribute (but this is true for all elements)
    • that would need JavaScript to move the data elsewhere
    • in double-quoted attributes, " and &thing; need escaping: " and &thing; respectively
  • raw text elements
    • <script> and <style> only
    • they are never rendered visible
    • but embedding your text in Javascript might be feasable
    • Javascript allows for multi-line strings with backticks
    • it could then be inserted dynamically
    • a literal </script is not allowed anywhere in <script>
  • escapable raw text elements
    • <textarea> and <title> only
    • <textarea> is a good candidate to wrap code in
    • it is totally legal to write </html> in there
    • not legal is the substring </textarea for obvious reasons
      • escape this special case with </textarea or similar
    • &thing; needs escaping: &thing;
  • foreign elements
    • elements from MathML and SVG namespaces
    • at least SVG allows embedding of HTML again...
    • and CDATA is allowed there, so it seems to have potential
• with XML syntax
  • covered by Konrad's answer

Note: > never needs escaping. Not even in normal elements.

SecurityElement.Escape

Set the CommandText as well, and call Fill on the SqlAdapter to retrieve the results in a DataSet:

var con = new SqlConnection();
con.ConnectionString = "connection string";
var com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "sp_returnTable";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);

(Example is using parameterless constructors for clarity; can be shortened by using other constructors.)

0xA0 (Unicode) is 0xC2A0 in UTF-8. .encode('utf8') will just take your Unicode 0xA0 and replace with UTF-8's 0xC2A0. Hence the apparition of 0xC2s... Encoding is not replacing, as you've probably realized now.

Can you use a List strings and then when you are done use strings.ToArray() to get the array of strings to work with?

I was originally looking for some GUI which would allow renaming using regular expressions and which had a preview of the result before applying changes.

On Linux I have successfully used krename, on Windows Total Commander does renaming with regexes, but I found no decent free equivalent for OSX, so I ended up writing a python script which works recursively and by default only prints the new file names without making any changes. Add the '-w' switch to actually modify the file names.

#!/usr/bin/python
# -*- coding: utf-8 -*-

import os
import fnmatch
import sys
import shutil
import re


def usage():
    print """
Usage:
        %s <work_dir> <search_regex> <replace_regex> [-w|--write]

        By default no changes are made, add '-w' or '--write' as last arg to actually rename files
        after you have previewed the result.
        """ % (os.path.basename(sys.argv[0]))


def rename_files(directory, search_pattern, replace_pattern, write_changes=False):

    pattern_old = re.compile(search_pattern)

    for path, dirs, files in os.walk(os.path.abspath(directory)):

        for filename in fnmatch.filter(files, "*.*"):

            if pattern_old.findall(filename):
                new_name = pattern_old.sub(replace_pattern, filename)

                filepath_old = os.path.join(path, filename)
                filepath_new = os.path.join(path, new_name)

                if not filepath_new:
                    print 'Replacement regex {} returns empty value! Skipping'.format(replace_pattern)
                    continue

                print new_name

                if write_changes:
                    shutil.move(filepath_old, filepath_new)
            else:
                print 'Name [{}] does not match search regex [{}]'.format(filename, search_pattern)

if __name__ == '__main__':
    if len(sys.argv) < 4:
        usage()
        sys.exit(-1)

    work_dir = sys.argv[1]
    search_regex = sys.argv[2]
    replace_regex = sys.argv[3]
    write_changes = (len(sys.argv) > 4) and sys.argv[4].lower() in ['--write', '-w']
    rename_files(work_dir, search_regex, replace_regex, write_changes)

Example use case

I want to flip parts of a file name in the following manner, i.e. move the bit m7-08 to the beginning of the file name:

# Before:
Summary-building-mobile-apps-ionic-framework-angularjs-m7-08.mp4

# After:
m7-08_Summary-building-mobile-apps-ionic-framework-angularjs.mp4

This will perform a dry run, and print the new file names without actually renaming any files:

rename_files_regex.py . "([^\.]+?)-(m\\d+-\\d+)" "\\2_\\1"

This will do the actual renaming (you can use either -w or --write):

rename_files_regex.py . "([^\.]+?)-(m\\d+-\\d+)" "\\2_\\1" --write

The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0^{[Ref 1]}.
The second is more readable.

The choice depends on user preference or the one which your coding standard mandates.

^{[Ref 1]} Reference C99 Standard 6.7.8.21:

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

You can give this a try. I am quite new to the forum but wanted to offer something that worked for me since I've gotten so much help from this site in the past. This is essentially a variation of the above, but I found it simpler.

Just paste this into the Userform_Initialize section of your userform code. Note you must already have a listbox on the userform or have it created dynamically above this code. Also please note the Array is a list of headings (below as "Header1", "Header2" etc. Replace these with your own headings. This code will then set up a heading bar at the top based on the column widths of the list box. Sorry it doesn't scroll - it's fixed labels.

More senior coders - please feel free to comment or improve this.

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

By implement this code in your ViewController you can get this effect Actually the trick is , hide the navigationBar when that Controller is launched

- (void)viewWillAppear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:YES animated:YES];
    [super viewWillAppear:animated];
}

and unhide the navigation bar when user leave that page do this is viewWillDisappear

- (void)viewWillDisappear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:NO animated:YES];
    [super viewWillDisappear:animated];
}

Yes, you can do this in a single line

let ms = Date.parse('2019-05-15 07:11:10.673Z');
console.log(ms);//1557904270673

Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:

jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.

EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.

I tried to optimise SBF's and Michael's code a bit to make it more compact.

I am relying on PowerShell's type coercion where it automatically converts strings to enum values, so I didn't define the lookup dictionary.

I also pulled out the block that adds the new path to the list based on a condition, so that work is done once and stored in a variable for re-use.

It is then applied permanently or just to the Session depending on the $PathContainer parameter.

We can put the block of code in a function or a ps1 file that we call directly from the command prompt. I went with DevEnvAddPath.ps1.

param(
    [Parameter(Position=0,Mandatory=$true)][String]$PathChange,

    [ValidateSet('Machine', 'User', 'Session')]
    [Parameter(Position=1,Mandatory=$false)][String]$PathContainer='Session',
    [Parameter(Position=2,Mandatory=$false)][Boolean]$PathPrepend=$false
)

[String]$ConstructedEnvPath = switch ($PathContainer) { "Session"{${env:Path};} default{[Environment]::GetEnvironmentVariable('Path', $containerType);} };
$PathPersisted = $ConstructedEnvPath -split ';';

if ($PathPersisted -notcontains $PathChange) {
    $PathPersisted = $(switch ($PathPrepend) { $true{,$PathChange + $PathPersisted;} default{$PathPersisted + $PathChange;} }) | Where-Object { $_ };

    $ConstructedEnvPath = $PathPersisted -join ";";
}

if ($PathContainer -ne 'Session') 
{
    # Save permanently to Machine, User
    [Environment]::SetEnvironmentVariable("Path", $ConstructedEnvPath, $PathContainer);
}

# Update the current session
${env:Path} = $ConstructedEnvPath;

I do something similar for a DevEnvRemovePath.ps1.

param(
    [Parameter(Position=0,Mandatory=$true)][String]$PathChange,

    [ValidateSet('Machine', 'User', 'Session')]
    [Parameter(Position=1,Mandatory=$false)][String]$PathContainer='Session'
)

[String]$ConstructedEnvPath = switch ($PathContainer) { "Session"{${env:Path};} default{[Environment]::GetEnvironmentVariable('Path', $containerType);} };
$PathPersisted = $ConstructedEnvPath -split ';';

if ($PathPersisted -contains $PathChange) {
    $PathPersisted = $PathPersisted | Where-Object { $_ -ne $PathChange };

    $ConstructedEnvPath = $PathPersisted -join ";";
}

if ($PathContainer -ne 'Session') 
{
    # Save permanently to Machine, User
    [Environment]::SetEnvironmentVariable("Path", $ConstructedEnvPath, $PathContainer);
}

# Update the current session
${env:Path} = $ConstructedEnvPath;

So far, they seem to work.

The most simple tool: use pdftk (or pdftk.exe, if you are on Windows):

pdftk 10_MB.pdf 100_MB.pdf cat output 110_MB.pdf

This will be a valid PDF. Download pdftk here.

Update: if you want really large (and valid!), non-optimized PDFs, use this command:

pdftk 100MB.pdf 100MB.pdf 100MB.pdf 100MB.pdf 100MB.pdf cat output 500_MB.pdf

or even (if you are on Linux, Unix or Mac OS X):

pdftk $(for i in $(seq 1 100); do echo -n "100MB.pdf "; done) cat output 10_GB.pdf

I came across this question and thought I would clarify that the lists() method of a eloquent builder object was depreciated in Laravel 5.2 and replaced with pluck().

// <= Laravel 5.1
Word_relation::where('word_one', $word_id)->lists('word_one')->toArray();
// >= Laravel 5.2
Word_relation::where('word_one', $word_id)->pluck('word_one')->toArray();

These methods can also be called on a Collection for example

// <= Laravel 5.1
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->lists('word_one');

// >= Laravel 5.2
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->pluck('word_one');

Downcasting is allowed when there is a possibility that it succeeds at run time:

Object o = getSomeObject(),
String s = (String) o; // this is allowed because o could reference a String

In some cases this will not succeed:

Object o = new Object();
String s = (String) o; // this will fail at runtime, because o doesn't reference a String

When a cast (such as this last one) fails at runtime a ClassCastException will be thrown.

In other cases it will work:

Object o = "a String";
String s = (String) o; // this will work, since o references a String

Note that some casts will be disallowed at compile time, because they will never succeed at all:

Integer i = getSomeInteger();
String s = (String) i; // the compiler will not allow this, since i can never reference a String.

I got the same error when the script file I was including container some special characters and when I was running in local moode (directly from local disk). I my case the solution was to explicitly tell the encoding:

<script src="my.js" charset="UTF-8"></script>

http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_now

"NOW() returns a constant time that indicates the time at which the statement began to execute. (Within a stored routine or trigger, NOW() returns the time at which the routine or triggering statement began to execute.) This differs from the behavior for SYSDATE(), which returns the exact time at which it executes as of MySQL 5.0.13. "

I received this error when I copied a class object using JSON.parse and JSON.stringify() which removed the function like:

class Rectangle {
  constructor(height, width) {
    this.height = height;
    this.width = width;
  }
  // Method
  calcArea() {
    return this.height * this.width;
  }
}

const square = new Rectangle(10, 10);

console.log('area of square: ', square.calcArea());

const squareCopy = JSON.parse(JSON.stringify(square));

// Will throw an exception since calcArea() is no longer function 
console.log('area of square copy: ', squareCopy.calcArea());

Using the deactivate feature provided by the venv's activate script requires you to trust the deactivation function to be properly coded to cleanly reset all environment variables back to how they were before— taking into account not only the original activation, but also any switches, configuration, or other work you may have done in the meantime.

It's probably fine, but it does introduce a new, non-zero risk of leaving your environment modified afterwards.

However, it's not technically possible for a process to directly alter the environment variables of its parent, so we can use a separate sub-shell to be absolutely sure our venvs don't leave any residual changes behind:

To activate:

$ bash --init-file PythonVenv/bin/activate

• This starts a new shell around the venv. Your original bash shell remains unmodified.

To deactivate:

$ exit OR [CTRL]+[D]

• This exits the entire shell the venv is in, and drops you back to the original shell from before the activation script made any changes to the environment.

Example:

[user@computer ~]$ echo $VIRTUAL_ENV
No virtualenv!

[user@computer ~]$ bash --init-file PythonVenv/bin/activate

(PythonVenv) [user@computer ~]$ echo $VIRTUAL_ENV
/home/user/PythonVenv

This will also work:

<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
                             Path=DataContext.AllowItemCommand}" />

ListView will inherit its DataContext from Window, so it's available at this point, too.
And since ListView, just like similar controls (e. g. Gridview, ListBox, etc.), is a subclass of ItemsControl, the Binding for such controls will work perfectly.

This is not a generic solution, but some databases allow you to use regular expressions to specify the columns.

For instance, in the case of Hive, the following query selects all columns except ds and hr:

SELECT `(ds|hr)?+.+` FROM sales

I got this error in an application that uses AppFabric. The clue was getting a DataCacheException in the stack trace. To see if this is the issue for you, run the following PowerShell command:

@("AppFabricCachingService","RemoteRegistry") | % { get-service $_ }

If either of these two services are stopped, then you will get this error.

Not sure what your target is, but do you want the text to come on the second line?

Here is your jsFiddle: http://jsfiddle.net/8kvWX/4/ just removed the following:

Im not sure if this is what your are looking for or not.

In my case, I had opened a query from data context, like

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)) _

... and then subsequently queried the same...

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)).ToList

Adding the .ToList to the first resolved my issue. I think it makes sense to wrap this in a property like:

Public ReadOnly Property Stores As List(Of Store)
    Get
        If _stores Is Nothing Then
            _stores = DataContext.Stores _
                .Where(Function(d) Filters.Contains(d.code)).ToList
        End If
        Return _stores
    End Get
End Property

Where _stores is a private variable, and Filters is also a readonly property that reads from AppSettings.

I use Calendar when I need some specific operations over the dates like moving in time, but Date I find it helpful when you need to format the date to adapt your needs, recently I discovered that Locale has a lot of useful operations and methods.So I'm using Locale right now!

function currentUrl() {
    $protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === FALSE ? 'http' : 'https';
    $host     = $_SERVER['HTTP_HOST'];
    $script   = $_SERVER['SCRIPT_NAME'];
    $params   = $_SERVER['QUERY_STRING'];

    return $protocol . '://' . $host . $script . '?' . $params;
}

Then add your value with something like;

echo currentUrl().'&value=myVal';

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Personally I don't like to use TempData, but I prefer to pass a strongly typed object as explained in Passing Information Between Controllers in ASP.Net-MVC.

You should always find a way to make it explicit and expected.

You can do something like this.

Select distinct name from  (SELECT r.name FROM outsider_role_mapping orm1 
    union all
SELECT r.name FROM user_role_mapping orm2
) tmp;

Try this:

String yourVal = "20.5";
float a = (Float.valueOf(yourVal)).floatValue(); 
System.out.println(a);

There are two possibilities, both from Quest Software, TOAD & SQL Navigator:

Here is the TOAD Freeware download: http://www.toadworld.com/Downloads/FreewareandTrials/ToadforOracleFreeware/tabid/558/Default.aspx

And the SQL Navigator (trial version): http://www.quest.com/sql-navigator/software-downloads.aspx

Or... You can use Blob to achive this.

Like:

pdf.addHTML($('#content'), y, x, options, function () {
    var blob = pdf.output("blob");
    window.open(URL.createObjectURL(blob));
});

That code let you create a Blob object inside the browser and show it in the new tab.

or you may try something like

"abc.def.ghi".substring(0,"abc.def.ghi".indexOf(c)-1);

Lets play trick with Boolean.compare(boolean, boolean). Default behavior of function: if both values are equal than it returns 0 otherwise -1.

public int valueOf(Boolean flag) {
   return Boolean.compare(flag, Boolean.TRUE) + 1;
}

Explanation: As we know default return of Boolean.compare is -1 in case of mis-match so +1 make return value to 0 for False and 1 for True

Comparator<User> cmp = new Comparator<User>() {
    @Override
    public int compare(User user1, User user2) {
        return user1.date.compareTo(user2.date);
    }
};

Collections.max(list, cmp);

If you need to order the files by specific parameter (e.g. date time):

gci *.log | sort LastWriteTime | % {$(Get-Content $_)} | Set-Content result.log

MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);

The former code will add the image at the end of the gallery. If you want to modify the date so it appears at the beginning or any other metadata, see the code below (Cortesy of S-K, samkirton):

Android WebView fix ERR_CACHE_MISS error solution

you just need add one line code <uses-permission android:name="android.permission.INTERNET"/> in your app/src/main/AndroidManifest.xml file as below screenshots shows.

2. after

It's not necessary to call repaint unless you need to render something specific onto a component. "Something specific" meaning anything that isn't provided internally by the windowing toolkit you're using.

These days implicit cursors are more efficient than explicit cursors.

You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:

Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);

In C# 6 you can use string interpolation:

string name = "John";
string result = $"Hello {name}";

The syntax highlighting for this in Visual Studio makes it highly readable and all of the tokens are checked.

This is my working code for express 4.0.

express 4.0 is very different from 3.0 and others.

4.0 you have /bin/www file, which you are going to add https here.

"npm start" is standard way you start express 4.0 server.

readFileSync() function should use __dirname get current directory

while require() use ./ refer to current directory.

First you put private.key and public.cert file under /bin folder, It is same folder as WWW file.

no such directory found error:

  key: fs.readFileSync('../private.key'),

  cert: fs.readFileSync('../public.cert')

error, no such directory found

  key: fs.readFileSync('./private.key'),

  cert: fs.readFileSync('./public.cert')

Working code should be

key: fs.readFileSync(__dirname + '/private.key', 'utf8'),

cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')

Complete https code is:

const https = require('https');
const fs = require('fs');

// readFileSync function must use __dirname get current directory
// require use ./ refer to current directory.

const options = {
   key: fs.readFileSync(__dirname + '/private.key', 'utf8'),
  cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')
};


 // Create HTTPs server.

 var server = https.createServer(options, app);

Two problems with your code:

1. You used a ' (tick) instead of a ` (back tick) to surround the commands that generate the string you want to store in the variable.
2. You didn't "echo" the variable "$filename" to the pipe into the "cut" command.

I'd change your code to "name=`echo $filename | cut -f 1 -d '.' `", as shown below (again, notice the back ticks surrounding the name variable definition):

$> filename=foo.txt
$> echo $filename
foo.txt
$> name=`echo $filename | cut -f1 -d'.'`
$> echo $name
foo
$> 

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

Use Rhino Mocks to set what calls, actions and exceptions might be expected. Assuming you can mock or stub out parts of your method. Hard to know without knowing some specifics here about the method, or even context.

Little sum up for searching by row:

This can be useful if you don't know the column values ??or if columns have non-numeric values

if u want get index number as integer u can also do:

item = df[4:5].index.item()
print(item)
4

it also works in numpy / list:

numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]

in [x] u pick number in range [4:7], for example if u want 6:

numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6

for DataFrame:

df[4:7]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449

or:

df[(df.index>=4) & (df.index<7)]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449   

I found this useful and easy to use, plus it looks pretty: http://maxailloud.github.io/confirm-bootstrap/.

To use it, include the .js file in your page then run:

$('your-link-selector').confirmModal();

There are various options you can apply to it, to make it look better when doing it to confirm a delete, I use:

$('your-link-selector').confirmModal({
    confirmTitle: 'Please confirm',
    confirmMessage: 'Are you sure you want to delete this?',
    confirmStyle: 'danger',
    confirmOk: '<i class="icon-trash icon-white"></i> Delete',
    confirmCallback: function (target) {
         //perform the deletion here, or leave this option
         //out to just follow link..
    }
});

There appear to be two problems.

1. You're using the ^ outside a [] which matches the start of the line
2. You're not using a * or + which means you will only match a single character.

I think you want the following regex @"([^a-zA-Z0-9\s])+"

That happens when the debugger hasn't hit a breakpoint or you haven't hit Break All (pause). It couldn't be that simple could it?

Perhaps a code example would help, I'm going to use C#, but you should be able to follow along.

Lets pretend we have an interface called IPayable

public interface IPayable
{
    public Pay(double amount);
}

Now, we have two concrete classes that implement this interface:

public class BusinessAccount : IPayable
{
    public void Pay(double amount)
    {
        //Logic
    }
}

public class CustomerAccount : IPayable
{
    public void Pay(double amount)
    {
        //Logic
    }
}

Now, lets pretend we have a collection of various accounts, to do this we will use a generic list of the type IPayable

List<IPayable> accountsToPay = new List<IPayable>();
accountsToPay.add(new CustomerAccount());
accountsToPay.add(new BusinessAccount());

Now, we want to pay $50.00 to all those accounts:

foreach (IPayable account in accountsToPay)
{
    account.Pay(50.00);
}

So now you see how interfaces are incredibly useful.

They are used on instantiated objects only. Not on static classes.

If you had made pay static, when looping through the IPayable's in accountsToPay there would be no way to figure out if it should call pay on BusinessAcount or CustomerAccount.

Slightly modified from: Python Pandas Dataframe: Normalize data between 0.01 and 0.99? but from some of the comments thought it was relevant (sorry if considered a repost though...)

I wanted customized normalization in that regular percentile of datum or z-score was not adequate. Sometimes I knew what the feasible max and min of the population were, and therefore wanted to define it other than my sample, or a different midpoint, or whatever! This can often be useful for rescaling and normalizing data for neural nets where you may want all inputs between 0 and 1, but some of your data may need to be scaled in a more customized way... because percentiles and stdevs assumes your sample covers the population, but sometimes we know this isn't true. It was also very useful for me when visualizing data in heatmaps. So i built a custom function (used extra steps in the code here to make it as readable as possible):

def NormData(s,low='min',center='mid',hi='max',insideout=False,shrinkfactor=0.):    
    if low=='min':
        low=min(s)
    elif low=='abs':
        low=max(abs(min(s)),abs(max(s)))*-1.#sign(min(s))
    if hi=='max':
        hi=max(s)
    elif hi=='abs':
        hi=max(abs(min(s)),abs(max(s)))*1.#sign(max(s))

    if center=='mid':
        center=(max(s)+min(s))/2
    elif center=='avg':
        center=mean(s)
    elif center=='median':
        center=median(s)

    s2=[x-center for x in s]
    hi=hi-center
    low=low-center
    center=0.

    r=[]

    for x in s2:
        if x<low:
            r.append(0.)
        elif x>hi:
            r.append(1.)
        else:
            if x>=center:
                r.append((x-center)/(hi-center)*0.5+0.5)
            else:
                r.append((x-low)/(center-low)*0.5+0.)

    if insideout==True:
        ir=[(1.-abs(z-0.5)*2.) for z in r]
        r=ir

    rr =[x-(x-0.5)*shrinkfactor for x in r]    
    return rr

This will take in a pandas series, or even just a list and normalize it to your specified low, center, and high points. also there is a shrink factor! to allow you to scale down the data away from endpoints 0 and 1 (I had to do this when combining colormaps in matplotlib:Single pcolormesh with more than one colormap using Matplotlib) So you can likely see how the code works, but basically say you have values [-5,1,10] in a sample, but want to normalize based on a range of -7 to 7 (so anything above 7, our "10" is treated as a 7 effectively) with a midpoint of 2, but shrink it to fit a 256 RGB colormap:

#In[1]
NormData([-5,2,10],low=-7,center=1,hi=7,shrinkfactor=2./256)
#Out[1]
[0.1279296875, 0.5826822916666667, 0.99609375]

It can also turn your data inside out... this may seem odd, but I found it useful for heatmapping. Say you want a darker color for values closer to 0 rather than hi/low. You could heatmap based on normalized data where insideout=True:

#In[2]
NormData([-5,2,10],low=-7,center=1,hi=7,insideout=True,shrinkfactor=2./256)
#Out[2]
[0.251953125, 0.8307291666666666, 0.00390625]

So now "2" which is closest to the center, defined as "1" is the highest value.

Anyways, I thought my application was relevant if you're looking to rescale data in other ways that could have useful applications to you.

try this:

<script src="https://maps.googleapis.com/maps/api/js"></script>

it works for me... the point is, change HTTP to HTTPS

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

Here's a good example:

int number = 1;
//D4 = pad with 0000
string outputValue = String.Format("{0:D4}", number);
Console.WriteLine(outputValue);//Prints 0001
//OR
outputValue = number.ToString().PadLeft(4, '0');
Console.WriteLine(outputValue);//Prints 0001 as well

The href is probably generated in a javascript function. For example with jQuery:

$(function() {
    $('a.view').attr('href', 'http://www.google.com');
});

also you can use this way. it will change your big drawble fit to your canvas:

Resources res = getResources();
Bitmap bitmap = BitmapFactory.decodeResource(res, yourDrawable);
yourCanvas.drawBitmap(bitmap, 0, 0, yourPaint);

Here is an example for all six boolean comparison operators (<, ==, >, >=, !=, <=):

BigDecimal big10 = new BigDecimal(10);
BigDecimal big20 = new BigDecimal(20);

System.out.println(big10.compareTo(big20) < -1);  // false
System.out.println(big10.compareTo(big20) <= -1); // true
System.out.println(big10.compareTo(big20) == -1); // true
System.out.println(big10.compareTo(big20) >= -1); // true
System.out.println(big10.compareTo(big20) > -1);  // false
System.out.println(big10.compareTo(big20) != -1); // false

System.out.println(big10.compareTo(big20) < 0);   // true
System.out.println(big10.compareTo(big20) <= 0);  // true
System.out.println(big10.compareTo(big20) == 0);  // false
System.out.println(big10.compareTo(big20) >= 0);  // false
System.out.println(big10.compareTo(big20) > 0);   // false
System.out.println(big10.compareTo(big20) != 0);  // true

System.out.println(big10.compareTo(big20) < 1);   // true
System.out.println(big10.compareTo(big20) <= 1);  // true
System.out.println(big10.compareTo(big20) == 1);  // false
System.out.println(big10.compareTo(big20) >= 1);  // false
System.out.println(big10.compareTo(big20) > 1);   // false
System.out.println(big10.compareTo(big20) != 1);  // true

You can monkey-patch the Array class:

class Array
    def contains_all?(ary)
        ary.uniq.all? { |x| count(x) >= ary.count(x) }
    end
end

test

irb(main):131:0> %w[a b c c].contains_all? %w[a b c]
=> true
irb(main):132:0> %w[a b c c].contains_all? %w[a b c c]
=> true
irb(main):133:0> %w[a b c c].contains_all? %w[a b c c c]
=> false
irb(main):134:0> %w[a b c c].contains_all? %w[a]
=> true
irb(main):135:0> %w[a b c c].contains_all? %w[x]
=> false
irb(main):136:0> %w[a b c c].contains_all? %w[]
=> true
irb(main):137:0> %w[a b c d].contains_all? %w[d c h]
=> false
irb(main):138:0> %w[a b c d].contains_all? %w[d b c]
=> true

Of course the method can be written as a standard-alone method, eg

def contains_all?(a,b)
    b.uniq.all? { |x| a.count(x) >= b.count(x) }
end

and you can invoke it like

contains_all?(%w[a b c c], %w[c c c])

Indeed, after profiling, the following version is much faster, and the code is shorter.

def contains_all?(a,b)
    b.all? { |x| a.count(x) >= b.count(x) }
end

You could use the window’s name window.name to store the information. This is known as JavaScript session. But it only works as long as the same window/tab is used.

Ok, The Windows 10 BatchFile is done works just like I had hoped. First press the windows key and R. Type mmc and Enter. In File Add SnapIn>Got to a specific Website and add it to the list. Press OK in the tab, and on the left side console root menu double click your site. Once it opens Add it to favourites. That should place it in C:\Users\user\AppData\Roaming\Microsoft\StartMenu\Programs\Windows Administrative Tools. I made a shortcut of this to a folder on the desktop. Right click the Shortcut and view the properties. In the Shortcut tab of the Properties click advanced and check the Run as Administrator. The Start in Location is also on the Shortcuts Tab you can add that to your batch file if you need. The Batch I made is as follows

@echo off
title Manage SiteEnviro
color 0a
:Clock
cls
echo Date:%date% Time:%time%
pause
cls
c:\WINDOWS\System32\netstat
c:\WINDOWS\System32\netstat -an
goto Greeting

:Greeting
cls
echo Open ShellSite
pause
cls
goto Manage SiteEnviro

:Manage SiteEnviro
"C:\Users\user\AppData\Roaming\Microsoft\Start Menu\Programs\Administrative Tools\YourCustomSavedMMC.msc"

You need to make a shortcut when you save this as a bat file and in the properties>shortcuts>advanced enable administrator access, can also set a keybind there and change the icon if you like. I probably did not need :Clock. The netstat commands can change to setting a hosted network or anything you want including nothing. Can Canscade websites in 1 mmc console and have more than 1 favourite added into the batch file.

Try implementing code given below

package com.kagrana;

import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Action;
import org.openqa.selenium.interactions.Actions;

public class DragAndDrop {
    @Test
    public void test() throws InterruptedException{
        WebDriver driver = new FirefoxDriver();
        driver.get("http://dhtmlx.com/docs/products/dhtmlxTree/");
        Thread.sleep(5000);
        driver.findElement(By.cssSelector("#treebox1 > div > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(3) > td:nth-child(2) > table > tbody > tr > td.standartTreeRow > span")).click();
        WebElement elementToMove = driver.findElement(By.cssSelector("#treebox1 > div > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(3) > td:nth-child(2) > table > tbody > tr > td.standartTreeRow > span"));
        WebElement moveToElement = driver.findElement(By.cssSelector("#treebox1 > div > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(2) > td:nth-child(2) > table > tbody > tr:nth-child(1) > td.standartTreeRow > span"));
        Actions dragAndDrop = new Actions(driver);
        Action action = dragAndDrop.dragAndDrop(elementToMove, moveToElement).build();
        action.perform();
    }
}

You can use strrpos() to find last match.

$string = "picture_0007_value";
$findChar =strrpos($string,"_");

$string[$findChar]=".";

echo $string;

Output : picture_0007.value

Under Winpython : the Winpython-64bit-.../python_.../DLLs directory the file cv2.pyd should be renamed to _cv2.pyd

Go to Build Gradle (Module:app) Change the following. In my case, I choose 25.0.3

android {

    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.example.cesarhcq.viisolutions"
        minSdkVersion 15
        targetSdkVersion 25

After that, it works fine!

The Template Editor will work for display purposes only. If you use the same editor (which makes sense because its an editor) and you supplied a value like 31/01/2010 - you'll get an error message saying the format is invalid.

Dim distinctValues As List(Of Double) = (From r In _
DirectCast(DataTable.AsEnumerable(),IEnumerable(Of DataRow)) Where (Not r.IsNull("ColName")) _
Select r.Field(Of Double)("ColName")).Distinct().ToList()

Actually, in iOS development by react-native when I use display: 'none' or something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 0,
    height: 0
  }
});

The iOS doesn't load anything else of the Image component like onLoad or etc, so I decided to use something like below:

const styles = StyleSheet.create({
  disappearImage: {
    width: 1,
    height: 1,
    position: 'absolute',
    top: -9000,
    opacity: 0
  }
});

If using pip 6.0 or newer, try adding the --no-cache-dir option (source).

If using pip older than pip 6.0, upgrade it with pip install -U pip.

A little bit off topic maybe, but for modern browsers (IE9 and newer) you can use the css odd/even selectors to achieve want you want.

tr:nth-child(even) { /* your alt-row stuff */}
tr:nth-child(odd) { /* the other rows */ }

or

tr { /* all table rows */ }
tr:nth-child(even) { /* your alt-row stuff */}

Another possibility is to use the Maven Shade Plugin, e.g. to exclude a logging properties file used only locally in your IDE:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>${maven-shade-plugin-version}</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>log4j2.xml</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
        </execution>
    </executions>
</plugin>

This will however exclude the files from every artifact, so it might not be feasible in every situation.

In addition to using jQuery methods, you can use the native cells collection that the <tr> gives you.

$(t)[0].cells[1].innerHTML

Assuming t is a DOM element, you could bypass the jQuery object creation.

t.cells[1].innerHTML

I have created a new library to implement swippable buttons which supports a variety of transitions and expandable buttons like iOS 8 mail app.

https://github.com/MortimerGoro/MGSwipeTableCell

This library is compatible with all the different ways to create a UITableViewCell and its tested on iOS 5, iOS 6, iOS 7 and iOS 8.

Here a sample of some transitions:

Border transition:

Clip transition

3D Transition:

document.getElementById('child') should return you the correct element - remember that id's need to be unique across a document to make it valid anyway.

edit : see this page - ids MUST be unique.

edit edit : alternate way to solve the problem :

<div onclick="test('child1')">
    Test
    <div id="child1">child</div>
</div>

then you just need the test() function to look up the element by id that you passed in.

Based on your requirements you can also do the following without libraries like jQuery:

Add this to your head:

window.onload = function () {
    document.getElementById("frmSubmit").onsubmit = function onSubmit(form) {
        var isValid = true;
        //validate your elems here
        isValid = false;

        if (!isValid) {
            alert("Please check your fields!");
            return false;
        }
        else {
            //you are good to go
            return true;
        }
    }
}

And your form may still look something like:

    <form id="frmSubmit" action="/Submit">
        <input type="submit" value="Submit" />
    </form>

This worked perfectly for me, although fetching all branches could be a bit too much:

git init
git remote add origin https://github.com/Vitosh/VBA_personal.git
git fetch --all
git checkout develop

I thought my problem and its solution could help.So i was getting this same error in my eclipse project.In my project i have couple of jar files and the NOCLASSDEFERROR was thrown for a file in the jar file.

My library files were part of a folder name "lib" in my project heirarchy.I changed my folders name to "libs" and voila it worked.

(I looked into the .classpath file and i had key-value pairs,and the entry for my jar file had key named "lib" and hence i thought probably changing from lib could help.)

This function is re-usable:

function usortarr(&$array, $key, $callback = 'strnatcasecmp') {
    uasort($array, function($a, $b) use($key, $callback) {
        return call_user_func($callback, $a[$key], $b[$key]);
    });
}

It works well on string values by default, but you'll have to sub the callback for a number comparison function if all your values are numbers.

There are a few libraries that help out here. For cmdline tools I sometimes use colorama.

e.g.

from colorama import init, Fore, Back, Style
init()

def cprint(msg, foreground = "black", background = "white"):
    fground = foreground.upper()
    bground = background.upper()
    style = getattr(Fore, fground) + getattr(Back, bground)
    print(style + msg + Style.RESET_ALL)

cprint("colorful output, wohoo", "red", "black")

But instead of using strings, you might want to use an enum and/or add a few checks. Not the prettiest solution, but works on osx/linux and windows and is easy to use.

Other threads about this topic and cross-platform support: e.g. here.

You can first choose which cells you don't want to be protected (to be user-editable) by setting the Locked status of them to False:

Worksheets("Sheet1").Range("B2:C3").Locked = False

Then, you can protect the sheet, and all the other cells will be protected. The code to do this, and still allow your VBA code to modify the cells is:

Worksheets("Sheet1").Protect UserInterfaceOnly:=True

or

Call Worksheets("Sheet1").Protect(UserInterfaceOnly:=True)

I also agree with the OP that all these things should come with Python already set. I guess we will have to deal with it until that day comes. Here is a solution that actually worked for me :

installing easy_install faster and easier

I hope it helps you or anyone with the same problem!

If your docker.service enabled on system startup

$ sudo systemctl enable docker

and your services in your docker-compose.yml has

restart: always

all of the services run when you reboot your system if you run below command only once

docker-compose up -d

You can first convert the enum to List and then use list contains method

enum Choices{A1, A2, B1, B2};

List choices = Arrays.asList(Choices.values());

//compare with enum value 
if(choices.contains(Choices.A1)){
   //do something
}

//compare with String value
if(choices.contains(Choices.valueOf("A1"))){
   //do something
}

There is another way to find the page update which could be useful for some occasions (if works:).

If the page has been indexed by Google, or by Wayback Machine you can try to find out what date(s) was(were) saved by them (these methods do not work for any page, and have some limitations, which are extensively investigated in this webmasters.stackexchange question's answers. But in many cases they can help you to find out the page update date(s):

1. Google way: Go by link https://www.google.com.ua/search?q=site%3Awww.example.com&biw=1855&bih=916&source=lnt&tbs=cdr%3A1%2Ccd_min%3A1%2F1%2F2000%2Ccd_max%3A&tbm=
   • You can change text in search field by any page URL you want.
   • For example, the current stackoverflow question page search gives us as a result May 14, 2014 - which is the question creation date:
2. Wayback machine way: Go by link https://web.archive.org/web/*/www.example.com
   • for this stackoverflow page wayback machine gives us more results: Saved 6 times between June 7, 2014 and November 23, 2016., and you can view all saved copies for each date

you can turn off the warning message as explained in the other answers or you can understand what's happening and fix it.

As of MySQL 5.7.5, the default SQL mode includes ONLY_FULL_GROUP_BY which means when you are grouping rows and then selecting something out of that groups, you need to explicitly say which row should that selection be made from.

Mysql needs to know which row in the group you're looking for, which gives you two options

• You can also add the column you want to the group statement group by rect.color, rect.value which can be what you want in some cases otherwise would return duplicate results with the same color which you may not want
• you could also use aggregate functions of mysql to indicate which row you are looking for inside the groups like AVG() MIN() MAX() complete list
• AND finally you can use ANY_VALUE() if you are sure that all the results inside the group are the same. doc

Various answers and notes are claiming that finish() can skip onPause() and onStop() and directly execute onDestroy(). To be fair, the Android documentation on this (http://developer.android.com/reference/android/app/Activity.html) notes "Activity is finishing or being destroyed by the system" which is pretty ambiguous but might suggest that finish() can jump to onDestroy().

The JavaDoc on finish() is similarly disappointing (http://developer.android.com/reference/android/app/Activity.html#finish()) and does not actually note what method(s) are called in response to finish().

So I wrote this mini-app below which logs each state upon entry. It includes a button which calls finish() -- so you can see the logs of which methods get fired. This experiment would suggested that finish() does indeed also call onPause() and onStop(). Here is the output I get:

Re-review the Android Activity Lifecycle reference. There is a nice picture, and the table showing what methods get called. reference Link google

https://developer.android.com/reference/android/app/Activity.html

• validate: validates the schema, no change happens to the database.
• update: updates the schema with current execute query.
• create: creates new schema every time, and destroys previous data.
• create-drop: drops the schema when the application is stopped or SessionFactory is closed explicitly.

Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

1. Can not instantiate abstract class: Classes defined as abstract may not be instantiated, and any class that contains at least one abstract method must also be abstract.

Example below :

abstract class AbstractClass
{

    abstract protected function getValue();
    abstract protected function prefixValue($prefix);


    public function printOut() {
        echo "Hello how are you?";
    }
}

$obj=new AbstractClass();
$obj->printOut();
//Fatal error: Cannot instantiate abstract class AbstractClass

2. Any class that contains at least one abstract method must also be abstract: Abstract class can have abstract and non-abstract methods, but it must contain at least one abstract method. If a class has at least one abstract method, then the class must be declared abstract.

Note: Traits support the use of abstract methods in order to impose requirements upon the exhibiting class.

Example below :

class Non_Abstract_Class
{
   abstract protected function getValue();

    public function printOut() {
        echo "Hello how are you?";
    }
}

$obj=new Non_Abstract_Class();
$obj->printOut();
//Fatal error: Class Non_Abstract_Class contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Non_Abstract_Class::getValue)

3. An abstract method can not contain body: Methods defined as abstract simply declare the method's signature - they cannot define the implementation. But a non-abstract method can define the implementation.

abstract class AbstractClass
{
   abstract protected function getValue(){
   return "Hello how are you?";
   }

    public function printOut() {
        echo $this->getValue() . "\n";
    }
}

class ConcreteClass1 extends AbstractClass
{
    protected function getValue() {
        return "ConcreteClass1";
    }

    public function prefixValue($prefix) {
        return "{$prefix}ConcreteClass1";
    }
}

$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."\n";
//Fatal error: Abstract function AbstractClass::getValue() cannot contain body

4. When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child :If you inherit an abstract class you have to provide implementations to all the abstract methods in it.

abstract class AbstractClass
{
    // Force Extending class to define this method
    abstract protected function getValue();

    // Common method
    public function printOut() {
        print $this->getValue() . "<br/>";
    }
}

class ConcreteClass1 extends AbstractClass
{
    public function printOut() {
        echo "dhairya";
    }

}
$class1 = new ConcreteClass1;
$class1->printOut();
//Fatal error: Class ConcreteClass1 contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (AbstractClass::getValue)

5. Same (or a less restricted) visibility:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child; additionally, these methods must be defined with the same (or a less restricted) visibility. For example, if the abstract method is defined as protected, the function implementation must be defined as either protected or public, but not private.

Note that abstract method should not be private.

abstract class AbstractClass
{

    abstract public function getValue();
    abstract protected function prefixValue($prefix);

        public function printOut() {
        print $this->getValue();
    }
}

class ConcreteClass1 extends AbstractClass
{
    protected function getValue() {
        return "ConcreteClass1";
    }

    public function prefixValue($prefix) {
        return "{$prefix}ConcreteClass1";
    }
}
$class1 = new ConcreteClass1;
$class1->printOut();
echo $class1->prefixValue('FOO_') ."<br/>";
//Fatal error: Access level to ConcreteClass1::getValue() must be public (as in class AbstractClass)

6. Signatures of the abstract methods must match:When inheriting from an abstract class, all methods marked abstract in the parent's class declaration must be defined by the child;the signatures of the methods must match, i.e. the type hints and the number of required arguments must be the same. For example, if the child class defines an optional argument, where the abstract method's signature does not, there is no conflict in the signature.

abstract class AbstractClass
{

    abstract protected function prefixName($name);

}

class ConcreteClass extends AbstractClass
{


    public function prefixName($name, $separator = ".") {
        if ($name == "Pacman") {
            $prefix = "Mr";
        } elseif ($name == "Pacwoman") {
            $prefix = "Mrs";
        } else {
            $prefix = "";
        }
        return "{$prefix}{$separator} {$name}";
    }
}

$class = new ConcreteClass;
echo $class->prefixName("Pacman"), "<br/>";
echo $class->prefixName("Pacwoman"), "<br/>";
//output: Mr. Pacman
//        Mrs. Pacwoman

7. Abstract class doesn't support multiple inheritance:Abstract class can extends another abstract class,Abstract class can provide the implementation of interface.But it doesn't support multiple inheritance.

interface MyInterface{
    public function foo();
    public function bar();
}

abstract class MyAbstract1{
    abstract public function baz();
}


abstract class MyAbstract2 extends MyAbstract1 implements MyInterface{
    public function foo(){ echo "foo"; }
    public function bar(){ echo "bar"; }
    public function baz(){ echo "baz"; }
}

class MyClass extends MyAbstract2{
}

$obj=new MyClass;
$obj->foo();
$obj->bar();
$obj->baz();
//output: foobarbaz

Note: Please note order or positioning of the classes in your code can affect the interpreter and can cause a Fatal error. So, when using multiple levels of abstraction, be careful of the positioning of the classes within the source code.

below example will cause Fatal error: Class 'horse' not found

class cart extends horse {
    public function get_breed() { return "Wood"; }
}

abstract class horse extends animal {
    public function get_breed() { return "Jersey"; }
}

abstract class animal {
    public abstract function get_breed();
}

$cart = new cart();
print($cart->get_breed());

It really depends on where your JavaScript code is located.

The problem is probably caused by the DOM not being loaded when the line

var systemStatus = document.getElementById("system-status");

is executed. You could try calling this in an onload event, or ideally use a DOM ready type event from a JavaScript framework.

You can do it this way:

(Edit: Considering that you're waiting for a response json with dataType: 'json')

.NET

public JsonResult Edit(EditPostViewModel data)
{
    if(ModelState.IsValid) 
    {
       // Save  
       return Json(new { Ok = true } );
    }

    return Json(new { Ok = false } );
}

JS:

success: function (data) {
    if (data.Ok) {
      alert('success');
    }
    else {
      alert('problem');
    }
},

If you need I can also explain how to do it by returning a error 500, and get the error in the event error (ajax). But in your case this may be an option

Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:

String to match: "my word"

String to search: "I'm searching for my funny words inside this text"

You need the following regex: /^(?=.*my)(?=.*word).*$/im

Explaining:

^ assert position at start of a line

?= Positive Lookahead

.* matches any character (except newline)

() Groups

$ assert position at end of a line

i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])

m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)

Test the Regex here: https://regex101.com/r/iS5jJ3/1

So, you can create a javascript function that:

1. Replace regex reserved characters to avoid errors
2. Split your string at spaces
3. Encapsulate your words inside regex groups
4. Create a regex pattern
5. Execute the regex match

Example:

function fullTextCompare(myWords, toMatch){_x000D_
    //Replace regex reserved characters_x000D_
    myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
    //Split your string at spaces_x000D_
    arrWords = myWords.split(" ");_x000D_
    //Encapsulate your words inside regex groups_x000D_
    arrWords = arrWords.map(function( n ) {_x000D_
        return ["(?=.*"+n+")"];_x000D_
    });_x000D_
    //Create a regex pattern_x000D_
    sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
    //Execute the regex match_x000D_
    return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
    fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
    fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);

Well, no. Why there should be? Just discard the string if you don't need it anymore.

&str is more useful than String when you need to only read a string, because it is only a view into the original piece of data, not its owner. You can pass it around more easily than String, and it is copyable, so it is not consumed by the invoked methods. In this regard it is more general: if you have a String, you can pass it to where an &str is expected, but if you have &str, you can only pass it to functions expecting String if you make a new allocation.

You can find more on the differences between these two and when to use them in the official strings guide.

Be careful to check if

display_errors

or

error_reporting

is active (not a comment) somewhere else in the ini file.

My development server refused to display errors after upgrade to Kubuntu 16.04 - I had checked php.ini numerous times ... turned out that there was a diplay_errors = off; about 100 lines below my

display_errors = on;

So remember the last one counts!

There's a native DOM API that achieves this out of the box — getBoundingClientRect:

document.querySelector("#whatever").getBoundingClientRect().right

Try the code

awk '{s=($3==0)?"-":$3/$4; print s}'

Here is a stripped down example, using as little HTML markup as possible.

The Basics

• The overlay is provided by the :before pseudo element on the .content container.

• No z-index is required, :before is naturally layered over the video element.

• The .content container is position: relative so that the position: absolute overlay is positioned in relation to it.

• The overlay is stretched to cover the entire .content div width with left / right / bottom and left set to 0.

• The width of the video is controlled by the width of its container with width: 100%

The Demo

.content {
  position: relative;
  width: 500px;
  margin: 0 auto;
  padding: 20px;
}
.content video {
  width: 100%;
  display: block;
}
.content:before {
  content: '';
  position: absolute;
  background: rgba(0, 0, 0, 0.5);
  border-radius: 5px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
}

<div class="content">
  <video id="player" src="https://upload.wikimedia.org/wikipedia/commons/transcoded/1/18/Big_Buck_Bunny_Trailer_1080p.ogv/Big_Buck_Bunny_Trailer_1080p.ogv.360p.vp9.webm" autoplay loop muted></video>
</div>

This should be more helpful for debug. Answer from @Juned Ahsan will not specify full URL and will not print multiple headers/parameters.

private String httpServletRequestToString(HttpServletRequest request) {
    StringBuilder sb = new StringBuilder();

    sb.append("Request Method = [" + request.getMethod() + "], ");
    sb.append("Request URL Path = [" + request.getRequestURL() + "], ");

    String headers =
        Collections.list(request.getHeaderNames()).stream()
            .map(headerName -> headerName + " : " + Collections.list(request.getHeaders(headerName)) )
            .collect(Collectors.joining(", "));

    if (headers.isEmpty()) {
        sb.append("Request headers: NONE,");
    } else {
        sb.append("Request headers: ["+headers+"],");
    }

    String parameters =
        Collections.list(request.getParameterNames()).stream()
            .map(p -> p + " : " + Arrays.asList( request.getParameterValues(p)) )
            .collect(Collectors.joining(", "));             

    if (parameters.isEmpty()) {
        sb.append("Request parameters: NONE.");
    } else {
        sb.append("Request parameters: [" + parameters + "].");
    }

    return sb.toString();
}

You can create a new group with both the apache user and FTP user as members and then make the permission on the upload folder 775. This should give both the apache and FTP users the ability to write to the files in the folder but keep everyone else from modifying them.

You could try Davis.js, it gives you routing in your JavaScript using pushState when available and without JavaScript it allows your server side code to handle the requests.

Place this line before the closing script tag,writing from memory:

window.onload  = GetTimeZoneOffset;

i think the question is how to call the javascript function on pageload

Underscore's extend is the easiest and quickest way to achieve this, like James commented.

Here's an example using underscore:

var _ = require('underscore'), // npm install underscore to install
  object1 = {name: "John"},
  object2 = {location: "San Jose"};

var target = _.extend(object1, object2);

object 1 will get the properties of object2 and be returned and assigned to target. You could do it like this as well, depending on whether you mind object1 being modified:

var target = {};
_.extend(target, object1, object2);

Remove the position: absolute; attribute in the style

Well, I'd say it depends what you want to see in the logs, doesn't it? If you're happy with what ex.Message provides, use that. Otherwise, use ex.toString() or even log the stack trace.

You can use the Bean Comparator to sort on any property in your custom class.

$http is a promise too, you can make it simpler:

return $q.all(tasks.map(function(d){
        return $http.post('upload/tasks',d).then(someProcessCallback, onErrorCallback);
    }));

new and delete are C++ primitives which declare a new instance of a class or delete it (thus invoking the destructor of the class for the instance).

malloc and free are C functions and they allocate and free memory blocks (in size).

Both use the heap to make the allocation. malloc and free are nonetheless more "low level" as they just reserve a chunk of memory space which will probably be associated with a pointer. No structures are created around that memory (unless you consider a C array to be a structure).

I'm going to provide a functional (immutable) way of doing it.

1. The standard and easy way of doing it is to use slicing:

   index_to_remove = 3
   data = [*range(5)]
   new_data = data[:index_to_remove] + data[index_to_remove + 1:]
   
   print(f"data: {data}, new_data: {new_data}")
   

   Output:

   data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
   

2. Use list comprehension:

   data = [*range(5)]
   new_data = [v for i, v in enumerate(data) if i != index_to_remove]
   
   print(f"data: {data}, new_data: {new_data}") 
   

   Output:

   data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
   

3. Use filter function:

   index_to_remove = 3
   data = [*range(5)]
   new_data = [*filter(lambda i: i != index_to_remove, data)]
   

   Output:

   data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
   

4. Using masking. Masking is provided by itertools.compress function in the standard library:

   from itertools import compress
   
   index_to_remove = 3
   data = [*range(5)]
   mask = [1] * len(data)
   mask[index_to_remove] = 0
   new_data = [*compress(data, mask)]
   
   print(f"data: {data}, mask: {mask}, new_data: {new_data}")
   

   Output:

   data: [0, 1, 2, 3, 4], mask: [1, 1, 1, 0, 1], new_data: [0, 1, 2, 4]
   

5. Use itertools.filterfalse function from Python standard library

   from itertools import filterfalse
   
   index_to_remove = 3
   data = [*range(5)]
   new_data = [*filterfalse(lambda i: i == index_to_remove, data)]
   
   print(f"data: {data}, new_data: {new_data}")
   

   Output:

   data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
   

OpenJDK is OK for the most cases, but Oracle JDK can be required for some bank client applications (my case) - I can't use OpenJDK.

I'm surprised that I don't see any answer with the default method (repository without external PPAs) in Ubuntu 12.10+ for Oracle's JDK - I will try to describe it.

• Install JavaPackage: sudo apt-get install java-package
• Download Oracle JDK from Oracle downloads page
• Make a Debian package from the downloaded .tar.gz archive: make-jpkg jdk-YOUR_VERSION-linux-PLATFORM.tar.gz This command will produce a .deb package.
• Install the package in your favourite way (for example, sudo dpkg -i oracle-java8-jdk_8u40_amd64.deb)

It's the officially supported way from Debian developers for installing Oracle JDK, and I suppose it's very simple.

For where field not empty this worked for me:

->where('table_name.field_name', '<>', '')

If you declare your callback as mentioned by @lex82 like

callback = "callback(item.id, arg2)"

You can call the callback method in the directive scope with object map and it would do the binding correctly. Like

scope.callback({arg2:"some value"});

without requiring for $parse. See my fiddle(console log) http://jsfiddle.net/k7czc/2/

Update: There is a small example of this in the documentation:

& or &attr - provides a way to execute an expression in the context of the parent scope. If no attr name is specified then the attribute name is assumed to be the same as the local name. Given and widget definition of scope: { localFn:'&myAttr' }, then isolate scope property localFn will point to a function wrapper for the count = count + value expression. Often it's desirable to pass data from the isolated scope via an expression and to the parent scope, this can be done by passing a map of local variable names and values into the expression wrapper fn. For example, if the expression is increment(amount) then we can specify the amount value by calling the localFn as localFn({amount: 22}).

Since you're using express, just add bodyParser:

app.use(express.bodyParser());

then your route automatically has access to the uploaded file(s) in req.files:

app.post('/todo/create', function (req, res) {
    // TODO: move and rename the file using req.files.path & .name)
    res.send(console.dir(req.files));  // DEBUG: display available fields
});

If you name the input control "todo" like this (in Jade):

form(action="/todo/create", method="POST", enctype="multipart/form-data")
    input(type='file', name='todo')
    button(type='submit') New

Then the uploaded file is ready by the time you get the path and original filename in 'files.todo':

• req.files.todo.path, and
• req.files.todo.name

other useful req.files properties:

• size (in bytes)
• type (e.g., 'image/png')
• lastModifiedate
• _writeStream.encoding (e.g, 'binary')

Yes, you can use substitutions and check against the original string:

if not x%str1:bcd=%==x%str1% echo It contains bcd

The %str1:bcd=% bit will replace a bcd in str1 with an empty string, making it different from the original.

If the original didn't contain a bcd string in it, the modified version will be identical.

Testing with the following script will show it in action:

@setlocal enableextensions enabledelayedexpansion
@echo off
set str1=%1
if not x%str1:bcd=%==x%str1% echo It contains bcd
endlocal

And the results of various runs:

c:\testarea> testprog hello

c:\testarea> testprog abcdef
It contains bcd

c:\testarea> testprog bcd
It contains bcd

A couple of notes:

• The if statement is the meat of this solution, everything else is support stuff.
• The x before the two sides of the equality is to ensure that the string bcd works okay. It also protects against certain "improper" starting characters.

This problems comes while .metadata of current workspace has been corrupted due to shut down Eclipse Unexpectedly. So if you face this problem just do the following steps:

• Create a new workspace. Import your existing projects to your new workspace.

you made it!

There are many ways to reload the current pages, but somehow using those approaches you can see page updated but not with few cache values will be there, so overcome that issue or if you wish to make hard requests then use the below code.

    location.reload(true);
    //Here, it will make a hard request or reload the current page and clear the cache as well.


    location.reload(false); OR location.reload();
    //It can be reload the page with cache

A Maven SNAPSHOT is an artifact created by a Maven build and pretends to help developers in the software development cycle. A SNAPSHOT is an artifact (or project build result ) that is not pretended to be used anywhere, it's only a temporarily .jar, ear, ... created to test the build process or to test new requirements that are not yet ready to go to a production environment. After you are happy with the SNAPSHOT artifact quality, you can create a RELEASE artifact that can be used by other projects or can be deployed itself.

In your project, you can define a SNAPSHOT using the version element in the pom.xml file of Maven:

<groupId>example.project.maven</groupId>
<artifactId>MavenEclipseExample</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<description>Maven pom example</description>

If you want to understand better Maven you can look into these articles too:

Thread.currentThread().isInterrupted() is superbly working. but this code is only pause the timer.

This code is stop and reset the thread timer. h1 is handler name. This code is add on inside your button click listener. w_h =minutes w_m =milli sec i=counter

 i=0;
            w_h = 0;
            w_m = 0;


            textView.setText(String.format("%02d", w_h) + ":" + String.format("%02d", w_m));
                        hl.removeCallbacksAndMessages(null);
                        Thread.currentThread().isInterrupted();


                        }


                    });


                }`

No, there is no way to specify defaults. I believer this is done on purpose to enhance readability, at the cost of a little more time (and, hopefully, thought) on the writer's end.

I think the proper approach to having a "default" is to have a new function which supplies that default to the more generic function. Having this, your code becomes clearer on your intent. For example:

func SaySomething(say string) {
    // All the complicated bits involved in saying something
}

func SayHello() {
    SaySomething("Hello")
}

With very little effort, I made a function that does a common thing and reused the generic function. You can see this in many libraries, fmt.Println for example just adds a newline to what fmt.Print would otherwise do. When reading someone's code, however, it is clear what they intend to do by the function they call. With default values, I won't know what is supposed to be happening without also going to the function to reference what the default value actually is.

I think you are looking for this: RowHeaderMouseDoubleClick event

private void DgwModificar_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e) {
...
}

to get the row index:

int indice = e.RowIndex

You might take a look at JavaScience's source for OpenSSLKey

There's code in there that does exactly what you want to do.

In fact, they have a lot of crypto source code available here.

None of the other suggestions worked for me, but this did:

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

Just checked out P4merge since I heard about it in another blog article:

Very slick interface, and FREE! I've been a faithful Araxis Merge user, but considering this is free and awesome, I'd encourage you to check it out.

When your program has more open descriptors than the open files ulimit (ulimit -a will list this), the kernel will refuse to open any more file descriptors. Make sure you don't have any file descriptor leaks - for example, by running it for a while, then stopping and seeing if any extra fds are still open when it's idle - and if it's still a problem, change the nofile ulimit for your user in /etc/security/limits.conf

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

I agree with @Brian Clapper. I have used SuperCSV as a parser though I've had mixed results. I enjoy the versatility of it, but there are some situations within my own csv files for which I have not been able to reconcile "yet". I have faith in this product and would recommend it overall--I'm just missing something simple, no doubt, that I'm doing in my own implementation.

SuperCSV can parse the columns into various formats, do edits on the columns, etc. It's worth taking a look-see. It has examples as well, and easy to follow.

The one/only limitation I'm having is catching an 'empty' column and parsing it into an Integer or maybe a blank, etc. I'm getting null-pointer errors, but javadocs suggest each cellProcessor checks for nulls first. So, I'm blaming myself first, for now. :-)

Anyway, take a look at SuperCSV. http://supercsv.sourceforge.net/

You can find the kth smallest element in O(n) time and constant space. If we consider the array is only for integers.

The approach is to do a binary search on the range of Array values. If we have a min_value and a max_value both in integer range, we can do a binary search on that range. We can write a comparator function which will tell us if any value is the kth-smallest or smaller than kth-smallest or bigger than kth-smallest. Do the binary search until you reach the kth-smallest number

Here is the code for that

class Solution:

def _iskthsmallest(self, A, val, k):
    less_count, equal_count = 0, 0

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

I recommend my solution. My situation: g++(cygwin) on win10

My solution: Write a .bat batch file and execute compiler in that batch. compileCpp.bat

@echo off  
set PATH=%PATH%;C:\cygwin64\bin\
rm %~n1.exe
c++.exe -g %~dpnx1 -o %~dpn1.exe
%~n1.exe  

Console:

NPP_EXEC: "runCpp"
NPP_SAVE: E:\hw.cpp
CD: E:\
Current directory: E:\
cmd /c C:\cygwin64\bin\compileCpp.bat "hw.cpp"
Process started >>>
Hello World<<< Process finished. (Exit code 0)

x86 is rather broad range of devices.

For totally generic x86 target, an assembly block with "rep movsd" could blast out zeros to memory 32-bits at time. Try to make sure the bulk of this work is DWORD aligned.

For chips with mmx, an assembly loop with movq could hit 64bits at a time.

You might be able to get a C/C++ compiler to use a 64-bit write with a pointer to a long long or _m64. Target must be 8 byte aligned for the best performance.

for chips with sse, movaps is fast, but only if the address is 16 byte aligned, so use a movsb until aligned, and then complete your clear with a loop of movaps

Win32 has "ZeroMemory()", but I forget if thats a macro to memset, or an actual 'good' implementation.

Toastr is a very nice component, and you can show messages with theses commands:

// for success - green box
toastr.success('Success messages');

// for errors - red box
toastr.error('errors messages');

// for warning - orange box
toastr.warning('warning messages');

// for info - blue box
toastr.info('info messages');

If you want to provide a title on the toastr message, just add a second argument:

// for info - blue box
toastr.success('The process has been saved.', 'Success');

you also can change the default behaviour using something like this:

toastr.options.timeOut = 3000; // 3s

See more on the github of the project.

Edits

A sample of use:

$(document).ready(function() {

    // show when page load
    toastr.info('Page Loaded!');

    $('#linkButton').click(function() {
       // show when the button is clicked
       toastr.success('Click Button');

    });

});

and a html:

<a id='linkButton'>Show Message</a>

findIndex works for modern browsers:

var myArr = [{id:'a'},{id:'myid'},{id:'c'}];
var index = myArr.findIndex(function(o){
  return o.id === 'myid';
})
if (index !== -1) myArr.splice(index, 1);

If you a framework like Bootstrap you can make any iframe video responsive by using this snippet:

<div class="embed-responsive embed-responsive-16by9">
    <iframe class="embed-responsive-item" src="vid.mp4" allowfullscreen></iframe>
</div>

This has been answered by numerous ways but what I came up with was the simplest and easiest for me with Bootstrap 3 and font awesome. I just did

$('a.toggler').on('click', function () {$('i', this).toggleClass('fa-caret-up');});

This just toggles the CSS class of the icon I want to show. I add the class toggler to the item I want to apply this to. This can be added onto any item you want to toggle an icon.

my issue was (master|REBASE 1/1)

this command worked for me

 git rebase --skip

Underscore Mixins

Extending on @emil_lundberg's answer, you can also write a "mixin" if you're using Underscore to make a custom function for sorting if it's a kind of sorting you might repeat in an application somewhere.

For example, maybe you have a controller or view sorting results with sort order of "ASC" or "DESC", and you want to toggle between that sort, you could do something like this:

Mixin.js

_.mixin({
    sortByOrder: function(stooges, prop, order) {
      if (String(order) === "desc") {
          return _.sortBy(stooges, prop).reverse();
      } else if (String(order) === "asc") {
          return _.sortBy(stooges, prop);
      } else {
          return stooges;
      }
    }
})

Usage Example

var sort_order = "asc";
var stooges = [
  {name: 'moe', age: 40}, 
  {name: 'larry', age: 50}, 
  {name: 'curly', age: 60},
  {name: 'July', age: 35},
  {name: 'mel', age: 38}
 ];

_.mixin({
    sortByOrder: function(stooges, prop, order) {
    if (String(order) === "desc") {
        return _.sortBy(stooges, prop).reverse();
    } else if (String(order) === "asc") {
        return _.sortBy(stooges, prop);
    } else {
        return stooges;
    }
  }
})


// find elements
var banner = $("#banner-message");
var sort_name_btn = $("button.sort-name");
var sort_age_btn = $("button.sort-age");

function showSortedResults(results, sort_order, prop) {
    banner.empty();
    banner.append("<p>Sorting: " + prop + ', ' + sort_order + "</p><hr>")
  _.each(results, function(r) {
    banner.append('<li>' + r.name + ' is '+ r.age + ' years old.</li>');
  }) 
}

// handle click and add class
sort_name_btn.on("click", function() {
  sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'name', sort_order);
  showSortedResults(sortedResults, sort_order, 'name');
})

sort_age_btn.on('click', function() {
    sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'age', sort_order);
  showSortedResults(sortedResults, sort_order, 'age');
})
