You may use an html parser (many useful links here: java html parser).

The process is called 'grabbing website content'. Search 'grab website content java' for further invertigation.

I had already installed pods. Build worked without any problems when I builded application on my device, but archive didn't work. I just run:

pod install

no new pods were installed, just .xcodeproj file got regenerated and archive started working

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

I have a also same problem.Change old version of FirebaseAuth to newer version. for me I change "com.google.firebase:firebase-auth:11.4.0" to "com.google.firebase:firebase-auth:11.8.0"

Just to give my 5 cents.

My date format is dd.mm.yyyy (UK format) and none of the above examples were working for me. All the parsers were considering mm as day and dd as month.

I've found this library: http://joey.mazzarelli.com/2008/11/25/easy-date-parsing-with-javascript/ and it worked, because you can say the order of the fields like this:

>>console.log(new Date(Date.fromString('09.05.2012', {order: 'DMY'})));
Wed May 09 2012 00:00:00 GMT+0300 (EEST)

I hope that helps someone.

I created a method just for that. I use it any time I need to manually update a ListView. Hopefully this gives you an idea of how to implement your own

public static void UpdateListView(List<SomeObject> SomeObjects, ListView ListVw)
{    
    if(ListVw != null)
    {
        final YourAdapter adapter = (YourAdapter) ListVw.getAdapter();

        //You'll have to create this method in your adapter class. It's a simple setter.
        adapter.SetList(SomeObjects);

        adapter.notifyDataSetChanged();
    }
}

I'm using an adapter that inherites from BaseAdapter. Should work for any other type of adapter.

You can also use myform.$invalid

E.g.

if($scope.myform.$invalid){return;}

use set to de-duplicate a list, return as list

def get_unique_list(lst):
        if isinstance(lst,list):
            return list(set(lst))

As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability:

/// <summary>
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// </summary>
/// <param name="url">The URL helper.</param>
/// <param name="actionName">The name of the action method.</param>
/// <param name="controllerName">The name of the controller.</param>
/// <param name="routeValues">The route values.</param>
/// <returns>The absolute URL.</returns>
public static string AbsoluteAction(this UrlHelper url,
    string actionName, string controllerName, object routeValues = null)
{
    string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

    return url.Action(actionName, controllerName, routeValues, scheme);
}

You can then simply use it like that in your view:

@Url.AbsoluteAction("Action", "Controller")

Dont forget

@ORM\HasLifecycleCallbacks()

Entity :

/**
     * Set gameDate
     *
     * @ORM\PrePersist
     */
    public function setGameDate()
    {
        $this->dateCreated = new \DateTime();

        return $this;
    }

View:

{{ item.gameDate|date('Y-m-d H:i:s') }}

>> Output 2013-09-18 16:14:20

I've experienced the same problem. One of the responds to your question led me to the following idea (which worked eventually). I use Python 3.7.

    # just an example 
    def func(): # define a function
       func.y = 4 # here y is a local variable, which I want to access; func.y defines 
                  # a method for my example function which will allow me to access 
                  # function's local variable y
       x = func.y + 8 # this is the main task for the function: what it should do
       return x

    func() # now I'm calling the function
    a = func.y # I put it's local variable into my new variable
    print(a) # and print my new variable

Then I launch this program in Windows PowerShell and get the answer 4. Conclusion: to be able to access a local function's variable one might add the name of the function and a dot before the name of the local variable (and then, of course, use this construction for calling the variable both in the function's body and outside of it). I hope this will help.

I had this problem with a fork from some online course. I cloned my fork and ran into a permissions error. I couldn't understand why it was insisting I was my user from my other company. But as the previous commenter mentioned I had the Clone git repositories using ssh setting checked and I had forgotten to add an ssh key to my new account. So I did and then still couldn't push because I got THIS error. The way I solved it was to push using the Github Desktop client.

Takeaways:

1. When you open a new GitHub account make sure to add an ssh key to it
2. Use different ssh keys for different accounts
3. In general I run into some GitHub issue on IntelliJ at least once or twice for every project. Make sure you have a copy of GitHub desktop and load your projects into it. It can and will help you with lots of problems you may run into with Intellij - not just this one. It's actually a really nice GUI client and free!
4. It probably makes sense to do what @yabin suggests and use the native client on a Mac

     $().ready(docReady);

     function docReady() {

            $("#myTextbox").focusout(uCaseMe);
     }

     function uCaseMe() {

            var val = $(this).val().toUpperCase();

            // Reset the current value to the Upper Case Value
            $(this).val(val);
        }

This is a reusable approach. Any number of textboxes can be done this way w/o naming them. A page wide solution could be achieved by changing the selector in docReady.

My example uses lost focus, the question did not specify as they type. You could trigger on change if thats important in your scenario.

Just type this command in your command line:

python manage.py changepassword yourusername

It works, when you use both lines:

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

I had a hell of a time finding this option in SQL Management Studio 2012, but I finally found it. The option is hiding in the Advanced button in the screen below.

I always assumed this contained just assumed advanced options for File generation, since that's what it's next to, but it turns out someone at MS is just really bad at UI design in this case. HTH somebody who comes to this thread like I did.

this should work:

public void setSections (Context c,  List<Section> sectionList){
    this.sectionList = sectionList;

    Type sectionListType = new TypeToken<ArrayList<Section>>(){}.getType();
    String sectionListString = new Gson().toJson(sectionList,sectionListType);

    SharedPreferences.Editor editor = getSharedPreferences(c).edit().putString(PREFS_KEY_SECTIONS, sectionListString);
    editor.apply();
}

them, to catch it just:

public List<Section> getSections(Context c){

    if(this.sectionList == null){
        String sSections = getSharedPreferences(c).getString(PREFS_KEY_SECTIONS, null);

        if(sSections == null){
            return new ArrayList<>();
        }

        Type sectionListType = new TypeToken<ArrayList<Section>>(){}.getType();
        try {

            this.sectionList = new Gson().fromJson(sSections, sectionListType);

            if(this.sectionList == null){
                return new ArrayList<>();
            }
        }catch (JsonSyntaxException ex){

            return new ArrayList<>();

        }catch (JsonParseException exc){

            return new ArrayList<>();
        }
    }
    return this.sectionList;
}

it works for me.

If you want to commit on top of the current HEAD with the exact state at a different commit, undoing all the intermediate commits, then you can use reset to create the correct state of the index to make the commit.

# Reset the index and working tree to the desired tree
# Ensure you have no uncommitted changes that you want to keep
git reset --hard 56e05fced

# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}

git commit -m "Revert to 56e05fced"

@JasonTrue is correct, that stripping HTML tags should not be done via regular expressions.

It's quite simple to strip HTML tags using HtmlAgilityPack:

public string StripTags(string input) {
    var doc = new HtmlDocument();
    doc.LoadHtml(input ?? "");
    return doc.DocumentNode.InnerText;
}

You could use assign, but using assign (or get) is often a symptom of a programming structure that is not very R like. Typically, lists or matrices allow cleaner solutions.

• with a list:

  A <- lapply (1 : 10, function (x) d + rnorm (3))
  

• with a matrix:

  A <- matrix (rep (d, each = 10) + rnorm (30), nrow = 10)
  

In my case there was a conflict in the namespaces , I have:

using System.Web.Mvc;

and

using System.Collections.Generic;

I explicitly want to use the Mvc one so I declared it as :

new System.Web.Mvc.SelectList(...)

hmm - pwd works for me on Vista...

Final EDIT: it works for me on Vista because WinAvr installed pwd.exe and added \Program Files\WinAvr\Utils\bin to my path.

You can't. @Alnitak's answer is the best you can do, and will give you all the new files in the time period it's checking for, but -ctime actually checks the modification time of the file's inode (file descriptor), and so will also catch any older files (for example) renamed in the last day.

Currently you can use it, changing the order: (it seems to be a bug)

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);

toolbar.setNavigationIcon(R.drawable.ic_good);
toolbar.setTitle("Title");
toolbar.setSubtitle("Sub");
toolbar.setLogo(R.drawable.ic_launcher);

You will have to access db through the ip of host machine, or if you want to access it via localhost:1521, then run webserver like -

docker run --net=host --name oracle-wls wls-image:latest

Prevent saving changes that require table re-creation

Five swift clicks

1. Tools
2. Options
3. Designers
4. Prevent saving changes that require table re-creation
5. OK.

After saving, repeat the proceudure to re-tick the box. This safe-guards against accidental data loss.

Further explanation

• By default SQL Server Management Studio prevents the dropping of tables, because when a table is dropped its data contents are lost.*

• When altering a column's datatype in the table Design view, when saving the changes the database drops the table internally and then re-creates a new one.

*Your specific circumstances will not pose a consequence since your table is empty. I provide this explanation entirely to improve your understanding of the procedure.

The other option is to tell EF to allow the column to be null:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
        modelBuilder.Entity<SomeObject>().Property(m => m.somefield).IsOptional();            
        base.OnModelCreating(modelBuilder);
}

This code should be in the object that inherits from DbContext.

Just push to the branch that the pull request references. As long as the pull request is still open, it should get updated with any added commits automatically.

This answer is obsolete. Technology has moved on. Unless you're working with legacy systems see Joel's answer.

There is no string concatenation operator in EL. If you don't need the concatenated string to pass into some other operation, just put these expressions next to each other:

${value}${(empty value)? 'none' : ' enabled'}

I made helper functions that were transferred from the below link into swift:

How can we programmatically detect which iOS version is device running on?

func SYSTEM_VERSION_EQUAL_TO(version: String) -> Bool {
    return UIDevice.currentDevice().systemVersion.compare(version,
        options: NSStringCompareOptions.NumericSearch) == NSComparisonResult.OrderedSame
}

func SYSTEM_VERSION_GREATER_THAN(version: String) -> Bool {
    return UIDevice.currentDevice().systemVersion.compare(version,
        options: NSStringCompareOptions.NumericSearch) == NSComparisonResult.OrderedDescending
}

func SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(version: String) -> Bool {
    return UIDevice.currentDevice().systemVersion.compare(version,
        options: NSStringCompareOptions.NumericSearch) != NSComparisonResult.OrderedAscending
}

func SYSTEM_VERSION_LESS_THAN(version: String) -> Bool {
    return UIDevice.currentDevice().systemVersion.compare(version,
        options: NSStringCompareOptions.NumericSearch) == NSComparisonResult.OrderedAscending
}

func SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(version: String) -> Bool {
    return UIDevice.currentDevice().systemVersion.compare(version,
        options: NSStringCompareOptions.NumericSearch) != NSComparisonResult.OrderedDescending
}

It can be used like so:

SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO("7.0")

Swift 4.2

func SYSTEM_VERSION_EQUAL_TO(version: String) -> Bool {
    return UIDevice.current.systemVersion.compare(version, options: .numeric) == .orderedSame
}

func SYSTEM_VERSION_GREATER_THAN(version: String) -> Bool {
    return UIDevice.current.systemVersion.compare(version, options: .numeric) == .orderedDescending
}

func SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(version: String) -> Bool {
    return UIDevice.current.systemVersion.compare(version, options: .numeric) != .orderedAscending
}

func SYSTEM_VERSION_LESS_THAN(version: String) -> Bool {
    return UIDevice.current.systemVersion.compare(version, options: .numeric) == .orderedAscending
}

func SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(version: String) -> Bool {
    return UIDevice.current.systemVersion.compare(version, options: .numeric) != .orderedDescending
}

Have you tried context editor? It is small and fast.

You can use the Windows 'SendTo' functionality to make running PS1 scripts easier. Using this method you can right click on a PS1 script and execute. This is doesn't exactly answer the OP question but it is close. Hopefully, this is useful to others. BTW.. this is helpful for a variety of other tasks.

• Locate / Search for Powershell.exe
• Right click on Powershell.exe and choose Open File Location
• Right click on Powershell.exe and choose Create Shortcut. Temporarily save some place like your desktop
• You might want to open as Admin by default. Select Shortcut > Properties > Advanced > Open As Admin
• Open the Sendto folder. Start > Run > Shell:Sendto
• Move the Powershell.exe shortcut to the Sendto folder
• You should now be able to right click on a PS1 script.
• Right Click on a PS1 file, Select the SendTo context option > Select the Powershell shortcut
• Your PS1 script should execute.

I tested dkarp's solution with gmail and it was filtered to spam. Use the Reply-To header instead (or in addition, although gmail apparently doesn't need it). Here's how linkedin does it:

Sender: [email protected]
From: John Doe via LinkedIn <[email protected]>
Reply-To: John Doe <[email protected]>
To: My Name <[email protected]>

Once I switched to this format, gmail is no longer filtering my messages as spam.

Say you have commit id 2 after commit 1 you would be able to run:

git diff 2 1 > mypatch.diff

where 2 and 1 are SHA hashes.

You should download MariaDB connector.
Then:

1. Expand your project.
2. Right-click on Libraries.
3. Select Add Jar/Folder.
4. Add mariadb-java-client-2.0.2.jar which you just downloaded.

This happened to me when I tried to install a newer version of PHP. After finding that I also would need to reconfigure Apache for that I switched back to the old PHP version. Here the solution which worked for me:

change the httpd.conf to the correct versions:

 PHPIniDir ...
 LoadModule php5_module ...

Changed the

PATH - Environment Variable

When that does not take any effect

rename or delete the new PHP(-Version)-Folder

For some reason the last step did the trick for me. Even after a restart it did not have an effect before doing this.

you don't need define positioning when you need vertical align center for inline and block elements you can take mentioned below idea:-

inline-elements :- <img style="vertical-align:middle" ...>
                   <span style="display:inline-block; vertical-align:middle"> foo<br>bar </span>  

block-elements :- <td style="vertical-align:middle"> ... </td>
                  <div style="display:table-cell; vertical-align:middle"> ... </div>

see the demo:- http://jsfiddle.net/Ewfkk/2/

Check out the docs here: https://matplotlib.org/users/legend_guide.html#legend-location

adding this simply worked to bring legend out of the plot:

plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)

It is the best way to remove the rounded in IOS.

textarea,
input[type="text"],
input[type="button"],
input[type="submit"] {
     -webkit-appearance: none;
     border-radius: 0;
}

Note: Please don't use this code for the Select Option. It will have problem on our select.

Here is what I did that worked great. I just imported an existing project under general instead of importing an android project.

I resolved by adding - %AppData%\npm\node_modules@angular\cli\bin\ path to my environment variables path

To assign multiple classes to an html element, include both class names within the quotations of the class attribute and have them separated by a space:

<article class="column wrapper"> 

In the above example, column and wrapper are two separate css classes, and both of their properties will be applied to the article element.

I faced with this problem if i leave the empty constructor in the receiver class. After the removing the empty contsructor onRreceive methos started working fine.

To sandwich an my element between the modal screen and a dialog, I need to lift my element above the modal-screen, and then lift the dialog above my element.

I had a small success by doing the following after creating the dialog on element $dlg.

$dlg.closest('.ui-dialog').css('zIndex',adjustment);

Since each dialog has a different starting z-index (they incrementally get larger) I make adjustment a string with a boost value, like this:

const adjustment = "+=99";

However, jQuery just keeps increasing the zIndex value on the modal screen, so by the second dialog, the sandwich no longer worked. I gave up on ui-dialog "modal", made it "false", and just created my own modal. It imitates jQueryUI exactly. Here it is:

CoverAll = {};
CoverAll.modalDiv = null;

CoverAll.modalCloak = function(zIndex) {
  var div = CoverAll.modalDiv;
  if(!CoverAll.modalDiv) {
    div = CoverAll.modalDiv = document.createElement('div');
    div.style.background = '#aaaaaa';
    div.style.opacity    = '0.3';
    div.style.position   = 'fixed';
    div.style.top        = '0';
    div.style.left       = '0';
    div.style.width      = '100%';
    div.style.height     = '100%';
  }
  if(!div.parentElement) {
    document.body.appendChild(div);
  }
  if(zIndex == null)
    zIndex = 100;
  div.style.zIndex  = zIndex;
  return div;
}

CoverAll.modalUncloak = function() {
  var div = CoverAll.modalDiv;
  if(div && div.parentElement) {
    document.body.removeChild(div);
  }
  return div;
}

SELECT COUNT(1)

    Dte BETWEEN CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(DATEADD(month, -1, GETDATE())) AS VARCHAR(2)) + '-20 00:00:00'
        AND CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(GETDATE()) AS VARCHAR(2)) + '-20 00:00:00'

Solved this by adding following

 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

Yes. You know that you can put any Object into the Object parameter of most JOptionPane.showXXX methods, and often that Object happens to be a JPanel.

In your situation, perhaps you could use a JPanel that has several JTextFields in it:

import javax.swing.*;

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField xField = new JTextField(5);
      JTextField yField = new JTextField(5);

      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("x:"));
      myPanel.add(xField);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("y:"));
      myPanel.add(yField);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("x value: " + xField.getText());
         System.out.println("y value: " + yField.getText());
      }
   }
}

playing with globals() makes it possible:

import random

alphabet = tuple('abcdefghijklmnopqrstuvwxyz')


print '\n'.join(repr(u) for u in globals() if not u.startswith('__'))

for i in xrange(8):
    globals()[''.join(random.sample(alphabet,random.randint(3,26)))] = random.choice(alphabet)

print

print '\n'.join(repr((u,globals()[u])) for u in globals() if not u.startswith('__'))

one result:

'alphabet'
'random'

('hadmgoixzkcptsbwjfyrelvnqu', 'h')
('nzklv', 'o')
('alphabet', ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'))
('random', <module 'random' from 'G:\Python27\lib\random.pyc'>)
('ckpnwqguzyslmjveotxfbadh', 'f')
('i', 7)
('xwbujzkicyd', 'j')
('isjckyngxvaofdbeqwutl', 'n')
('wmt', 'g')
('aesyhvmw', 'q')
('azfjndwhkqgmtyeb', 'o')

I used random because you don't explain which names of "variables" to give, and which values to create. Because i don't think it's possible to create a name without making it binded to an object.

Implementing the two directives already worked for me from within "C:\Windows\SysWOW64"

regsvr32 MSCOMCTL.OCX
regtlib msdatsrc.tlb

It's worth noting that the DOS box should be in Administrator mode. Prior to this, I kept having errors in the vein "Class MSComctlLib.TreeView of control tvTreeView was not a loaded control class" and "Class MSComctlLib.ListView of control lvListView was not a loaded control class".

I am also using Visual Studio 6 on 64 bit Windows 7, with SP6 updates. I was driven here due to the same problem. In my case, I did not need to go through the registry.

function function_one() {_x000D_
    function_two(); // considering the next alert, I figured you wanted to call function_two first_x000D_
    alert("The function called 'function_one' has been called.");_x000D_
}_x000D_
_x000D_
function function_two() {_x000D_
    alert("The function called 'function_two' has been called.");_x000D_
}_x000D_
_x000D_
function_one();

A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).

If your script always requires an Administrator's privileges then:

runas /user:Administrator "python your_script.py"

One approach you could take is the following method:

// Counts how many of a certain character occurs in the given string
public static int CharCountInString(char chr, string str)
{
    return str.Split(chr).Length-1;
}

As per the parameters this method returns the count of a specific character within a specific string.

This method works by splitting the string into an array by the specified character and then returning the length of that array -1.

I haven't tested this on a 500 code, but it works on others like 200, 302 and 404.

response=$(curl --write-out '%{http_code}' --silent --output /dev/null servername)

Note, format provided for --write-out should be quoted. As suggested by @ibai, add --head to make a HEAD only request. This will save time when the retrieval is successful since the page contents won't be transmitted.

An exemple of the only solution that works for me in the simple usecase where I am on a fork and I want to checkout a new branch from a tag that is on the main project repository ( here upstream )

git fetch upstream --tags

Give me

From https://github.com/keycloak/keycloak
   90b29b0e31..0ba9055d28  stage      -> upstream/stage
 * [new tag]    11.0.0     -> 11.0.0

Then I can create a new branch from this tag and checkout on it

git checkout -b tags/<name> <newbranch>

git checkout tags/11.0.0 -b v11.0.0

As others have pointed out, params values can come from the query string of a GET request, or the form data of a POST request, but there's also a third place they can come from: The path of the URL.

As you might know, Rails uses something called routes to direct requests to their corresponding controller actions. These routes may contain segments that are extracted from the URL and put into params. For example, if you have a route like this:

match 'products/:id', ...

Then a request to a URL like http://example.com/products/42 will set params[:id] to 42.

Numpy arrays have an astype method. Just do y.astype(int).

Note that it might not even be necessary to do this, depending on what you're using the array for. Bool will be autopromoted to int in many cases, so you can add it to int arrays without having to explicitly convert it:

>>> x
array([ True, False,  True], dtype=bool)
>>> x + [1, 2, 3]
array([2, 2, 4])

Your error shows you are not compiling file with the definition of the insert function. Update your command to include the file which contains the definition of that function and it should work.

Since there's no answer stating just this, summarized succinctly:

Carriage Return (MAC pre-OSX)

• CR
• \r
• ASCII code 13

Line Feed (Linux, MAC OSX)

• LF
• \n
• ASCII code 10

Carriage Return and Line Feed (Windows)

• CRLF
• \r\n
• ASCII code 13 and then ASCII code 10

If you see ASCII code in a strange format, they are merely the number 13 and 10 in a different radix/base, usually base 8 (octal) or base 16 (hexadecimal).

http://www.bluesock.org/~willg/dev/ascii.html

Get the current URL including the query string.

echo url()->full();

in Kotlin :

val jsonArrayString = "['A','B','C']"

val gson = Gson()

val listType: Type = object : TypeToken<List<String?>?>() {}.getType()

val stringList : List<String> = gson.fromJson(
                            jsonArrayString,
                            listType)

For me, I would go with interfaces in many cases. But I prefer abstract classes in some cases.

Classes in OO generaly refers to implementation. I use abstract classes when I want to force some implementation details to the childs else I go with interfaces.

Of course, abstract classes are useful not only in forcing implementation but also in sharing some specific details among many related classes.

void foo(vector<int> test)

vector would be passed by value in this.

You have more ways to pass vectors depending on the context:-

1) Pass by reference:- This will let function foo change your contents of the vector. More efficient than pass by value as copying of vector is avoided.

2) Pass by const-reference:- This is efficient as well as reliable when you don't want function to change the contents of the vector.

I find that the --tree-filter option used in other answers can be very slow, especially on larger repositories with lots of commits.

Here is the method I use to completely remove a directory from the git history using the --index-filter option, which runs much quicker:

# Make a fresh clone of YOUR_REPO
git clone YOUR_REPO
cd YOUR_REPO

# Create tracking branches of all branches
for remote in `git branch -r | grep -v /HEAD`; do git checkout --track $remote ; done

# Remove DIRECTORY_NAME from all commits, then remove the refs to the old commits
# (repeat these two commands for as many directories that you want to remove)
git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY_NAME/' --prune-empty --tag-name-filter cat -- --all
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

# Ensure all old refs are fully removed
rm -Rf .git/logs .git/refs/original

# Perform a garbage collection to remove commits with no refs
git gc --prune=all --aggressive

# Force push all branches to overwrite their history
# (use with caution!)
git push origin --all --force
git push origin --tags --force

You can check the size of the repository before and after the gc with:

git count-objects -vH

The default port for SQL Server Database Engine is 1433.

And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

Without JavaScript, it's not possible to open two pages by clicking one link unless both pages are framed on the one page that opens from clicking the link. With JS it's trivial:

<p><a href="#" onclick="window.open('http://google.com');
    window.open('http://yahoo.com');">Click to open Google and Yahoo</a></p>

Do note that this will be blocked by popup blockers built into web browsers but you are usually notified of this.

There's no built-in method for doing this in Python 2. If you need this, you need to write a prepend() method/function that operates on the OrderedDict internals with O(1) complexity.

For Python 3.2 and later, you should use the move_to_end method. The method accepts a last argument which indicates whether the element will be moved to the bottom (last=True) or the top (last=False) of the OrderedDict.

Finally, if you want a quick, dirty and slow solution, you can just create a new OrderedDict from scratch.

Details for the four different solutions:

Extend OrderedDict and add a new instance method

from collections import OrderedDict

class MyOrderedDict(OrderedDict):

    def prepend(self, key, value, dict_setitem=dict.__setitem__):

        root = self._OrderedDict__root
        first = root[1]

        if key in self:
            link = self._OrderedDict__map[key]
            link_prev, link_next, _ = link
            link_prev[1] = link_next
            link_next[0] = link_prev
            link[0] = root
            link[1] = first
            root[1] = first[0] = link
        else:
            root[1] = first[0] = self._OrderedDict__map[key] = [root, first, key]
            dict_setitem(self, key, value)

Demo:

>>> d = MyOrderedDict([('a', '1'), ('b', '2')])
>>> d
MyOrderedDict([('a', '1'), ('b', '2')])
>>> d.prepend('c', 100)
>>> d
MyOrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> d.prepend('a', d['a'])
>>> d
MyOrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> d.prepend('d', 200)
>>> d
MyOrderedDict([('d', 200), ('a', '1'), ('c', 100), ('b', '2')])

Standalone function that manipulates OrderedDict objects

This function does the same thing by accepting the dict object, key and value. I personally prefer the class:

from collections import OrderedDict

def ordered_dict_prepend(dct, key, value, dict_setitem=dict.__setitem__):
    root = dct._OrderedDict__root
    first = root[1]

    if key in dct:
        link = dct._OrderedDict__map[key]
        link_prev, link_next, _ = link
        link_prev[1] = link_next
        link_next[0] = link_prev
        link[0] = root
        link[1] = first
        root[1] = first[0] = link
    else:
        root[1] = first[0] = dct._OrderedDict__map[key] = [root, first, key]
        dict_setitem(dct, key, value)

Demo:

>>> d = OrderedDict([('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'c', 100)
>>> d
OrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'a', d['a'])
>>> d
OrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> ordered_dict_prepend(d, 'd', 500)
>>> d
OrderedDict([('d', 500), ('a', '1'), ('c', 100), ('b', '2')])

Use OrderedDict.move_to_end() (Python >= 3.2)

Python 3.2 introduced the OrderedDict.move_to_end() method. Using it, we can move an existing key to either end of the dictionary in O(1) time.

>>> d1 = OrderedDict([('a', '1'), ('b', '2')])
>>> d1.update({'c':'3'})
>>> d1.move_to_end('c', last=False)
>>> d1
OrderedDict([('c', '3'), ('a', '1'), ('b', '2')])

If we need to insert an element and move it to the top, all in one step, we can directly use it to create a prepend() wrapper (not presented here).

Create a new OrderedDict - slow!!!

If you don't want to do that and performance is not an issue then easiest way is to create a new dict:

from itertools import chain, ifilterfalse
from collections import OrderedDict


def unique_everseen(iterable, key=None):
    "List unique elements, preserving order. Remember all elements ever seen."
    # unique_everseen('AAAABBBCCDAABBB') --> A B C D
    # unique_everseen('ABBCcAD', str.lower) --> A B C D
    seen = set()
    seen_add = seen.add
    if key is None:
        for element in ifilterfalse(seen.__contains__, iterable):
            seen_add(element)
            yield element
    else:
        for element in iterable:
            k = key(element)
            if k not in seen:
                seen_add(k)
                yield element

d1 = OrderedDict([('a', '1'), ('b', '2'),('c', 4)])
d2 = OrderedDict([('c', 3), ('e', 5)])   #dict containing items to be added at the front
new_dic = OrderedDict((k, d2.get(k, d1.get(k))) for k in \
                                           unique_everseen(chain(d2, d1)))
print new_dic

output:

OrderedDict([('c', 3), ('e', 5), ('a', '1'), ('b', '2')])

In Eclipse, you will find it under the project properties > C/C++ Build > Settings > MinGW C++ Linker > Misc

You must add it to the "linker flags" at the top; nowhere else. Then just rebuild.

I have found that linking those statically explodes the size up to 1,400kb even with optimizations. It's 277kb larger compared to just copying over the shared DLLs. It's 388kb larger as well after UPXing everything. Very lose/lose here. Just include the DLLs as the end-user can decide to delete them or not if they have them installed elsewhere.

I have been using this function for a while with no problems. You just need to provide the number columns there are in the csv file, and it will take the header names from the first row and create the table for you:

create or replace function data.load_csv_file
    (
        target_table  text, -- name of the table that will be created
        csv_file_path text,
        col_count     integer
    )

    returns void

as $$

declare
    iter      integer; -- dummy integer to iterate columns with
    col       text; -- to keep column names in each iteration
    col_first text; -- first column name, e.g., top left corner on a csv file or spreadsheet

begin
    set schema 'data';

    create table temp_table ();

    -- add just enough number of columns
    for iter in 1..col_count
    loop
        execute format ('alter table temp_table add column col_%s text;', iter);
    end loop;

    -- copy the data from csv file
    execute format ('copy temp_table from %L with delimiter '','' quote ''"'' csv ', csv_file_path);

    iter := 1;
    col_first := (select col_1
                  from temp_table
                  limit 1);

    -- update the column names based on the first row which has the column names
    for col in execute format ('select unnest(string_to_array(trim(temp_table::text, ''()''), '','')) from temp_table where col_1 = %L', col_first)
    loop
        execute format ('alter table temp_table rename column col_%s to %s', iter, col);
        iter := iter + 1;
    end loop;

    -- delete the columns row // using quote_ident or %I does not work here!?
    execute format ('delete from temp_table where %s = %L', col_first, col_first);

    -- change the temp table name to the name given as parameter, if not blank
    if length (target_table) > 0 then
        execute format ('alter table temp_table rename to %I', target_table);
    end if;
end;

Here is a possible solution the solution #3 on my comments to blubill's answer:

yourscript.php
========================
<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if (file_exists($dir) == false) 
    {
        echo 'Directory "', $dir, '" not found!';
    } 
    else 
    {
        $dir_contents = scandir($dir);

        foreach ($dir_contents as $file) 
        {
            $file_type = strtolower(end(explode('.', $file)));
            if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true)     
            {
                $name = basename($file);
                echo "<img src='img.php?name={$name}' />";
            }
        }
    }
?>


img.php
========================
<?php
    $name = $_GET['name'];
    $mimes = array
    (
        'jpg' => 'image/jpg',
        'jpeg' => 'image/jpg',
        'gif' => 'image/gif',
        'png' => 'image/png'
    );

    $ext = strtolower(end(explode('.', $name)));

    $file = '/home/users/Pictures/'.$name;
    header('content-type: '. $mimes[$ext]);
    header('content-disposition: inline; filename="'.$name.'";');
    readfile($file);
?>

You can start by reading the data structure alignment wikipedia article to get a better understanding of data alignment.

From the wikipedia article:

Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

From 6.54.8 Structure-Packing Pragmas of the GCC documentation:

For compatibility with Microsoft Windows compilers, GCC supports a set of #pragma directives which change the maximum alignment of members of structures (other than zero-width bitfields), unions, and classes subsequently defined. The n value below always is required to be a small power of two and specifies the new alignment in bytes.

1. #pragma pack(n) simply sets the new alignment.
2. #pragma pack() sets the alignment to the one that was in effect when compilation started (see also command line option -fpack-struct[=] see Code Gen Options).
3. #pragma pack(push[,n]) pushes the current alignment setting on an internal stack and then optionally sets the new alignment.
4. #pragma pack(pop) restores the alignment setting to the one saved at the top of the internal stack (and removes that stack entry). Note that #pragma pack([n]) does not influence this internal stack; thus it is possible to have #pragma pack(push) followed by multiple #pragma pack(n) instances and finalized by a single #pragma pack(pop).

Some targets, e.g. i386 and powerpc, support the ms_struct #pragma which lays out a structure as the documented __attribute__ ((ms_struct)).

1. #pragma ms_struct on turns on the layout for structures declared.
2. #pragma ms_struct off turns off the layout for structures declared.
3. #pragma ms_struct reset goes back to the default layout.

Try this:

=IF(NOT(ISERROR(MATCH(A3,worksheet2!A:A,0))),COUNTIF(worksheet2!A:A,A3),"No Match Found")

You can get it to display time. From that you will probably have to have two controls (one date, one time) the accomplish what you want.

I cannot get a match using Xpather, but the following worked for me with plain XML and XSL files in Microsoft's XML Notepad:

<xsl:value-of select="count(//td[text()='&nbsp;'])" />

The value returned is 1, which is the correct value in my test case.

However, I did have to declare nbsp as an entity within my XML and XSL using the following:

<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#160;"> ]>

I'm not sure if that helps you, but I was able to actually find nbsp using an XPath expression.

Edit: My code sample actually contains the characters ' ' but the JavaScript syntax highlight converts it to the space character. Don't be mislead!

Here is a way to do it with PHP PEAR

// Pear Mail Library
require_once "Mail.php";

$from = '<[email protected]>'; //change this to your email address
$to = '<[email protected]>'; // change to address
$subject = 'Insert subject here'; // subject of mail
$body = "Hello world! this is the content of the email"; //content of mail

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => '[email protected]', //your gmail account
        'password' => 'snip' // your password
    ));

// Send the mail
$mail = $smtp->send($to, $headers, $body);

//check mail sent or not
if (PEAR::isError($mail)) {
    echo '<p>'.$mail->getMessage().'</p>';
} else {
    echo '<p>Message successfully sent!</p>';
}

If you use Gmail SMTP remember to enable SMTP in your Gmail account, under settings

EDIT: If you can't find Mail.php on debian/ubuntu you can install php-pear with

sudo apt install php-pear

Then install the mail extention:

sudo pear install mail
sudo pear install Net_SMTP
sudo pear install Auth_SASL
sudo pear install mail_mime

Then you should be able to load it by simply require_once "Mail.php" else it is located here: /usr/share/php/Mail.php

 function resize() {
        var map_obj = document.getElementById("map_canvas");

      /*  map_obj.style.width = "500px";

        if (map) {
            map.checkResize();
            map.panTo(new GLatLng(lat,lon));
        }
    }

Original Answer: Resetting a multi-stage form with jQuery

Mike's suggestion (from the comments) to keep checkbox and selects intact!

Warning: If you're creating elements (so they're not in the dom), replace :hidden with [type=hidden] or all fields will be ignored!

$(':input','#myform')
  .removeAttr('checked')
  .removeAttr('selected')
  .not(':button, :submit, :reset, :hidden, :radio, :checkbox')
  .val('');

use a debugging software how to identify where the code is running slowly ?

just think you have a obstacle while you are in motion then it will decrease your speed

like that unwanted reallocation's looping,buffer overflows,searching,memory leakages etc operations consumes more execution power it will effect adversely over performance of the code, Be sure to add -pg to compilation before profiling:

g++ your_prg.cpp -pg or cc my_program.cpp -g -pg as per your compiler

haven't tried it yet but I've heard good things about google-perftools. It is definitely worth a try.

valgrind --tool=callgrind ./(Your binary)

It will generate a file called gmon.out or callgrind.out.x. You can then use kcachegrind or debugger tool to read this file. It will give you a graphical analysis of things with results like which lines cost how much.

i think so

In case one does not have sudo privilege, but still needs to install the library.

Download source for the software/library using:

apt-get source libaio

or

wget https://src.fedoraproject.org/lookaside/pkgs/libaio/libaio-0.3.110.tar.gz/2a35602e43778383e2f4907a4ca39ab8/libaio-0.3.110.tar.gz

unzip the library

Install with the following command to user-specific library:

make prefix=`pwd`/usr install #(Copy from INSTALL file of libaio-0.3.110)

or

make prefix=/path/to/your/lib/libaio install

Include libaio library into LD_LIBRARY_PATH for your app:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/your/lib/libaio/lib

Now, your app should be able to find libaio.so.1

Try this cmd in terminal

$ ulimit -c unlimited

As I understand you use ASP.NET authentication and to set cookies persistent you need to set FormsAuthenticationTicket.IsPersistent = true It is the main idea.

bool isPersisted = true;
var authTicket = new FormsAuthenticationTicket(
1,
user_name, 
DateTime.Now,
DateTime.Now.AddYears(1),//Expiration (you can set it to 1 year)
isPersisted,//THIS IS THE MAIN FLAG
addition_data);
    HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, authTicket );
    if (isPersisted)
        authCookie.Expires = authTicket.Expiration;

HttpContext.Current.Response.Cookies.Add(authCookie);

There are many JSON libraries available in Java.

The most notorious ones are: Jackson, GSON, Genson, FastJson and org.json.

There are typically three things one should look at for choosing any library:

1. Performance
2. Ease of use (code is simple to write and legible) - that goes with features.
3. For mobile apps: dependency/jar size

Specifically for JSON libraries (and any serialization/deserialization libs), databinding is also usually of interest as it removes the need of writing boiler-plate code to pack/unpack the data.

For 1, see this benchmark: https://github.com/fabienrenaud/java-json-benchmark I did using JMH which compares (jackson, gson, genson, fastjson, org.json, jsonp) performance of serializers and deserializers using stream and databind APIs. For 2, you can find numerous examples on the Internet. The benchmark above can also be used as a source of examples...

Quick takeaway of the benchmark: Jackson performs 5 to 6 times better than org.json and more than twice better than GSON.

For your particular example, the following code decodes your json with jackson:

public class MyObj {

    private List<Interest> interests;

    static final class Interest {
        private String interestKey;
    }

    private static final ObjectMapper MAPPER = new ObjectMapper();
    public static void main(String[] args) throws IOException {
        MyObj o = JACKSON.readValue("{\"interests\": [{\"interestKey\": \"Dogs\"}, {\"interestKey\": \"Cats\" }]}", MyObj.class);
    }
}

Let me know if you have any questions.

The endpoint of the term is the URL that is focused on creating a request. Take a look at the following examples from different points:

/api/groups/6/workings/1
/api/v2/groups/5/workings/2
/api/workings/3

They can clearly access the same source in a given API.

"Add a reference to MySql.Data.dll" means you need to add a library reference to the downloaded connector. The IDE will link the database connection library with your application when it compiles.

Step-by-Step Example

I downloaded the binary (no installer) zip package from the MySQL web site, extracted onto the desktop, and did the following:

1. Create a new project in Visual Studio
2. In the Solution Explorer, under the project name, locate References and right-click on it. Select "Add Reference".
3. In the "Add Reference" dialog, switch to the "Browse" tab and browse to the folder containing the downloaded connector. Navigate to the "bin" folder, and select the "MySql.Data.dll" file. Click OK.
4. At the top of your code, add using MySql.Data.MySqlClient;. If you've added the reference correctly, IntelliSense should offer to complete this for you.

StewieFG suggestion is valid but if you want to add the recipient name use this, with what Marco has posted above but is email address first and display name second:

msg.To.Add(new MailAddress("[email protected]","Your name 1"));
msg.To.Add(new MailAddress("[email protected]","Your name 2"));

Use toFixed to convert it to a string with some decimal places shaved off, and then convert it back to a number.

+(0.1 + 0.2).toFixed(12) // 0.3

It looks like IE's toFixed has some weird behavior, so if you need to support IE something like this might be better:

Math.round((0.1 + 0.2) * 1e12) / 1e12

<table border="1" cellspacing="0" cellpadding="0">
    <tr>
        <td>
            <table border="0">
                <tr>
                    <td>one</td>
                    <td>two</td>
                </tr>
                <tr>
                    <td>one</td>
                </tr>
            </table>
        </td>
    </tr>
</table>

This is a pure JavaScript solution without any libraries or plugins:

document.addEventListener('click', function (e) {
    if (hasClass(e.target, 'bu')) {
        // .bu clicked
        // Do your thing
    } else if (hasClass(e.target, 'test')) {
        // .test clicked
        // Do your other thing
    }
}, false);

where hasClass is

function hasClass(elem, className) {
    return elem.className.split(' ').indexOf(className) > -1;
}

Live demo

Credit goes to Dave and Sime Vidas

Using more modern JS, hasClass can be implemented as:

function hasClass(elem, className) {
    return elem.classList.contains(className);
}

You can initialize after filling the array or you can write:

 small =~ unsigned(0)/2; // Using the bit-wise complement to flip 0's bits and dividing by 2 because unsigned can hold twice the +ve value an

integer can hold.

 big =- 1*(small) - 1;

instead of:

big = small = values[0]

because when you write this line before filling the array, big and small values will equal to a random leftover value (as integer is a POD) from the memory and if those numbers are either bigger or smaller than any other value in you array, you will get them as an output.

Look up NR and FNR in the awk manual and then ask yourself what is the condition under which NR==FNR in the following example:

$ cat file1
a
b
c

$ cat file2
d
e

$ awk '{print FILENAME, NR, FNR, $0}' file1 file2
file1 1 1 a
file1 2 2 b
file1 3 3 c
file2 4 1 d

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

1 - You can script sshpass's ssh command like this:

#!/bin/bash

export SSHPASS=password
sshpass -e ssh -oBatchMode=no user@host

2 - You can script sshpass's sftp commandlike this:

#!/bin/bash

export SSHPASS=password

sshpass -e sftp -oBatchMode=no -b - user@host << !
   put someFile
   get anotherFile
   bye
!

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

I have very easy way to do this but now sure its the foolproof way There is my code PullDownListView.java

package com.myproject.widgets;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.AbsListView;
import android.widget.AbsListView.OnScrollListener;
import android.widget.ListView;

/**

public class PullDownListView extends ListView implements OnScrollListener {

    private ListViewTouchEventListener mTouchListener;
    private boolean pulledDown;

    public PullDownListView(Context context) {
        super(context);
        init();
    }

    public PullDownListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public PullDownListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        setOnScrollListener(this);
    }

    private float lastY;

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            lastY = ev.getRawY();
        } else if (ev.getAction() == MotionEvent.ACTION_MOVE) {
            float newY = ev.getRawY();
            setPulledDown((newY - lastY) > 0);
            postDelayed(new Runnable() {
                @Override
                public void run() {
                    if (isPulledDown()) {
                        if (mTouchListener != null) {
                            mTouchListener.onListViewPulledDown();
                            setPulledDown(false);
                        }
                    }
                }
            }, 400);
            lastY = newY;
        } else if (ev.getAction() == MotionEvent.ACTION_UP) {
            lastY = 0;
        }
        return super.dispatchTouchEvent(ev);
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {
        setPulledDown(false);
    }

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
    }

    public interface ListViewTouchEventListener {
        public void onListViewPulledDown();
    }

    public void setListViewTouchListener(
            ListViewTouchEventListener touchListener) {
        this.mTouchListener = touchListener;
    }

    public ListViewTouchEventListener getListViewTouchListener() {
        return mTouchListener;
    }

    public boolean isPulledDown() {
        return pulledDown;
    }

    public void setPulledDown(boolean pulledDown) {
        this.pulledDown = pulledDown;
    }
}

You just need to implement ListViewTouchEventListener on your activity where you want to use this ListView and set the listener

I have it implemented in PullDownListViewActivity

package com.myproject.activities;

import android.app.Activity;
import android.os.Bundle;

/**
 * @author Pushpan
 *
 */
public class PullDownListViewActivity extends Activity implements ListViewTouchEventListener {

    private PullDownListView listView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        listView = new PullDownListView(this);
        setContentView(listView);
        listView.setListViewTouchListener(this);

        //setItems in listview
    }

    public void onListViewPulledDown(){
        Log.("PullDownListViewActivity", "ListView pulled down");
    }
}

It works for me :)

In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.

When running the Team Explorer version, only the Blank Solution option was available.

The Team Explorer EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"

Once I launched the correct EXE, Visual Studio started working as expected.

The Professional EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"

This solved my issue, and the reason was I had enterprise edition previously installed and then uninstalled and installed the professional edition. Team Explorer was not modified later when I moved to professional from enterprise edition.

Converting of a hash map to a string of query parameters:

Map<String, String> params = new HashMap<>();
params.put("msisdn", msisdn);
params.put("email", email);
params.put("clientVersion", clientVersion);
params.put("clientType", clientType);
params.put("issuerName", issuerName);
params.put("applicationName", applicationName);

UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url);
for (Map.Entry<String, String> entry : params.entrySet()) {
    builder.queryParam(entry.getKey(), entry.getValue());
}

HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");

HttpEntity<String> response = restTemplate.exchange(builder.toUriString(), HttpMethod.GET, new HttpEntity(headers), String.class);

Turn on Client Statistics by doing one of the following:

• Menu: Query > Include client Statistics
• Toolbar: Click the button (next to Include Actual Execution Time)
• Keyboard: Shift-Alt-S

Then you get a new tab which records the timings, IO data and rowcounts etc for (up to) the last 10 exections (plus averages!):

Path.GetDirectoryName(filename);

I had a similar problem when I recreated my workspace that was fixed in the following way:

Go to Eclipse -> Preferences, under Java select "Installed JREs" and check one of the boxes to specify a default JRE. Click OK and then go back to your project's properties. Go to the "Java Build Path" section and choose the "Libraries" tab. Remove the unbound System Default library, then click the "Add Library" button. Select "JRE System Library" and you should be good to go!

Height is missing a p from its value.

Should be height:200*p*x

Click "query tool" button in the list of "tool".

And then click the "open file" image button in the tool bar.

The simple way to get any row in csv file

import csv
csvfile = open('some.csv','rb')
csvFileArray = []
for row in csv.reader(csvfile, delimiter = '.'):
    csvFileArray.append(row)
print(csvFileArray[0])

How floats work

When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.

float vs display:inline

Before the invention of display:inline-block, websites use float to set elements beside each other. float is preferred over display:inline since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.

Float problems

The main problem is that we're using float against its intended purpose.

Another is that while float allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>, the <div> will not impart 100px in height to the container.

Unlike position:absolute, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.

Clearfix to the rescue

What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear.

Examples

Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.

What you have

Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:

• The first clearfix you have appends an invisible pseudo-element, which is styled clear:both, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.

• The second one appends the style display:inline-block which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.

• This was the reapplication of display:block due to IE-MAC rule above. This rule was "hidden" from IE-MAC.

All in all, these 3 rules keep the .clearfix working cross-browser, with old browsers in mind.

If you need to handle values that cannot be converted separately, you can use this method:

try {
    $valueToUse = trim($stringThatMightBeNumeric) + 0;
} catch (\Throwable $th) {
    // bail here if you need to
}

Not tested, but I think this will be close?

SELECT m1.id
FROM mytable m1
INNER JOIN mytable m2 ON m1.id < m2.id
GROUP BY m1.id
HAVING SUM(m1.cash) > 500
ORDER BY m1.id
LIMIT 1,2

The idea is to SUM up all the previous rows, get only the ones where the sum of the previous rows is > 500, then skip one and return the next one.

select min(table.id), table.column1
from table 
group by table.column1

Of course, to see the result in logcat, you should set the Log level at least to "Info" (Log level in logcat); otherwise, as it happened to me, you won't see your output.

var newTH = document.createElement('th');
newTH.onclick = function() {
      //Your code here
}

return b(); calls the function b(), and returns its result.

return b; returns a reference to the function b, which you can store in a variable to call later.

Favicons only work when served from a web-server which sets mime-types correctly for served content. Loading from a local file might not work in chromium. Loading from an incorrectly configured web-server will not work.

Web-servers such as lighthttpd must be configured manually to set the mime type correctly.

Because of the likelihood that mimetype assignment will not work in all environments, I would suggest you use an inline base64 encoded ico file instead. This will load faster as well, as it reduces the number of http requests sent to the server.

On POSIX based systems you can base64 encode a file with the base64 command.

To create a base64 encoded ico line use the command:

$ base64 favicon.ico --wrap 0

And insert the output into the line:

<link href="data:image/x-icon;base64,HERE" rel="icon" type="image/x-icon" />

Replacing the word HERE like so:

<link href="data:image/x-icon;base64,AAABAAEAEBAQAAEABAAoAQAAFgAAACgAAAAQAAAAIAAAAAEABAAAAAAAgAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAA////AERpOgA5cCcA7vDtAF6jSABllFcAuuCvAK2trQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAFjMzMzMzNxARYzMzMzVBEEERYzMzNhERZxRGMzZxQEA2FER3cRSAgTNxgEEREIQBMzFIARERFEEzNhERARFAATMzYREBEAhBMzMzEYEBFEEzMzNhEQQRQDMzMzcRgEAAMzMzNhERgIEzMzMyERgEQDMzMzMRAEgEMzMzMxERAEEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" rel="icon" type="image/x-icon" />

Try this code:

s = input() 
a = int(input()) 
b = s.replace(s[a],'')
print(b)

Uh, WHERE mydate<='2008-11-25' is the way to do it. That should work.

Do you get an error message? Are you using an ancient version of MySQL?

Edit: The following works fine for me on MySQL 5.x

create temporary table foo(d datetime);
insert into foo(d) VALUES ('2000-01-01');
insert into foo(d) VALUES ('2001-01-01');
select * from foo where d <= '2000-06-01';

If u want to join two dataframes in pandas you can simply use available attributes like merge or concatenate. For example if I have two dataframes df1 and df2 I can join them by:

newdataframe=merge(df1,df2,left_index=True,right_index=True)

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

I wondered why this appeared during my unit tests.

I have added a method declaration to a protocol which included throws; but the potentially throwing method wasn't even used in that particular test. Enabling Zombies in test sounded like too much trouble.

Turns out a ?K clean did the trick. I'm always flabberghasted when that solves actual problems.

I don't try changing sequence via setval. But using ALTER I was issued how to write sequence name properly. And this only work for me:

1. Check required sequence name using SELECT * FROM information_schema.sequences;

2. ALTER SEQUENCE public."table_name_Id_seq" restart {number};

   In my case it was ALTER SEQUENCE public."Services_Id_seq" restart 8;

Also there is a page on wiki.postgresql.org where describes a way to generate sql script to fix sequences in all database tables at once. Below the text from link:

Save this to a file, say 'reset.sql'

SELECT 'SELECT SETVAL(' ||
       quote_literal(quote_ident(PGT.schemaname) || '.' || quote_ident(S.relname)) ||
       ', COALESCE(MAX(' ||quote_ident(C.attname)|| '), 1) ) FROM ' ||
       quote_ident(PGT.schemaname)|| '.'||quote_ident(T.relname)|| ';'
FROM pg_class AS S,
     pg_depend AS D,
     pg_class AS T,
     pg_attribute AS C,
     pg_tables AS PGT
WHERE S.relkind = 'S'
    AND S.oid = D.objid
    AND D.refobjid = T.oid
    AND D.refobjid = C.attrelid
    AND D.refobjsubid = C.attnum
    AND T.relname = PGT.tablename
ORDER BY S.relname;

Run the file and save its output in a way that doesn't include the usual headers, then run that output. Example:

psql -Atq -f reset.sql -o temp
psql -f temp
rm temp

And the output will be a set of sql commands which look exactly like this:

SELECT SETVAL('public."SocialMentionEvents_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."SocialMentionEvents";
SELECT SETVAL('public."Users_Id_seq"', COALESCE(MAX("Id"), 1) ) FROM public."Users";

SQL Server ignores trailing whitespace when comparing strings, so ' ' = ''. Just use the following query for your update

UPDATE table
SET col1 = NULL
WHERE col1 = ''

NULL values in your table will stay NULL, and col1s with any number on space only characters will be changed to NULL.

If you want to do it during your copy from one table to another, use this:

INSERT INTO newtable ( col1, othercolumn )
SELECT
   NULLIF(col1, ''),
   othercolumn
FROM table

If you have not pushed the changes already:

git rm -r --cached .
git add .
git commit -m 'clear git cache'
git push

In light of Django 1.8's release (and the formalization of the Model _meta API, I figured I would update this with a more recent answer.

Assuming the same model:

class Client(Model):
    name = CharField(max_length=150)
    email = EmailField(max_length=100, verbose_name="E-mail")

Django <= 1.7

fields = [(f.verbose_name, f.name) for f in Client._meta.fields]
>>> fields
[(u'ID', u'id'), (u'name', u'name'), (u'E-mail', u'email')]

Django 1.8+ (formalized Model _meta API)

Changed in Django 1.8:

The Model _meta API has always existed as a Django internal, but wasn’t formally documented and supported. As part of the effort to make this API public, some of the already existing API entry points have changed slightly. A migration guide has been provided to assist in converting your code to use the new, official API.

In the below example, we will utilize the formalized method for retrieving all field instances of a model via Client._meta.get_fields():

fields = [(f.verbose_name, f.name) for f in Client._meta.get_fields()]
>>> fields
[(u'ID', u'id'), (u'name', u'name'), (u'E-mail', u'email')]

Actually, it has been brought to my attention that the above is slightly overboard for what was needed (I agree!). Simple is better than complex. I am leaving the above for reference. However, to display in the template, the best method would be to use a ModelForm and pass in an instance. You can iterate over the form (equivalent of iterating over each of the form's fields) and use the label attribute to retrieve the verbose_name of the model field, and use the value method to retrieve the value:

from django.forms import ModelForm
from django.shortcuts import get_object_or_404, render
from .models import Client

def my_view(request, pk):
    instance = get_object_or_404(Client, pk=pk)
    
    class ClientForm(ModelForm):
        class Meta:
            model = Client
            fields = ('name', 'email')

    form = ClientForm(instance=instance)

    return render(
        request, 
        template_name='template.html',
        {'form': form}
    )

Now, we render the fields in the template:

<table>
    <thead>
        {% for field in form %}
            <th>{{ field.label }}</th>
        {% endfor %}
    </thead>
    <tbody>
        <tr>
            {% for field in form %}
                <td>{{ field.value|default_if_none:'' }}</td>
            {% endfor %}
        </tr>
    </tbody>
</table>

It's not that above answers are incorrect, but I find this code extremely easy to understand and therefore I am sharing it here with everyone. And there is also the check for WRITE_CONTACTS permission.

Use jQuery.In the HTML page -

<button type="button">Click Me</button>

<script>
$(document).ready(function() {
$("button").click(function(){
  $.ajax({
    url:"php_page.php", //the page containing php script
    type: "POST", //request type
    success:function(result){
    alert(result);
    }
  });
});
})
</script>

Php page -

echo "Hello";

System.out.println(pageCrawling.getHtmlFromURL("http://ipecho.net/plain"));

I was confused as I knew VueJS should only contain 1 root element and yet I was still getting this same "template syntax error Component template should contain exactly one root element..." error on an extremely simple component. Turns out I had just mispelled </template> as </tempate> and that was giving me this same error in a few files I copied and pasted. In summary, check your syntax for any mispellings in your component.

has_key is fast and efficient.

Instead of array use an hash:

valueTo1={"a","b","c"}

if valueTo1.has_key("a"):
        print "Found key in dictionary"

Syntax:

CASE value WHEN [compare_value] THEN result 
[WHEN [compare_value] THEN result ...] 
[ELSE result] 
END

Alternative: CASE WHEN [condition] THEN result [WHEN [condition] THEN result ...]

The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.

Regarding the original question asked in the title ...

• sudo apt-get install libtcnative-1

• or if you are on RHEL Linux yum install tomcat-native

The documentation states you need http://tomcat.apache.org/native-doc/

• sudo apt-get install libapr1.0-dev libssl-dev
• or RHEL yum install apr-devel openssl-devel

Please define what you mean by "empty".

The test I normally use is isset().

My 2 cents - you don't need to store the excel as a physical file on the server - instead, store it in the (Session) Cache. Use a uniquely generated name for your Cache variable (that stores that excel file) - this will be the return of your (initial) ajax call. This way you don't have to deal with file access issues, managing (deleting) the files when not needed, etc. and, having the file in the Cache, is faster to retrieve it.

The accepted answer works like a charm unless you're applying it to a vector. Since a vector is non-recursive, you'll get an error like this

$ operator is invalid for atomic vectors

You can use [ in that case

foo[order(foo["V1"]),]

You can try:

sudo npm i -g npm

I found the cleanest way of doing it is this.

Tested on Django 3.1.5

class MyForm(forms.Form):
    my_boolean = forms.BooleanField(required=False, initial=True)

I found the answer here

Resurrecting the dead here, but just in case someone stumbles against this like myself. I know where to get the maximum value of a double, the (more) interesting part was to how did they get to that number.

double has 64 bits. The first one is reserved for the sign.

Next 11 represent the exponent (that is 1023 biased). It's just another way to represent the positive/negative values. If there are 11 bits then the max value is 1023.

Then there are 52 bits that hold the mantissa.

This is easily computed like this for example:

public static void main(String[] args) {

    String test = Strings.repeat("1", 52);

    double first = 0.5;
    double result = 0.0;
    for (char c : test.toCharArray()) {
        result += first;
        first = first / 2;
    }

    System.out.println(result); // close approximation of 1
    System.out.println(Math.pow(2, 1023) * (1 + result));
    System.out.println(Double.MAX_VALUE);

} 

You can also prove this in reverse order :

    String max = "0" + Long.toBinaryString(Double.doubleToLongBits(Double.MAX_VALUE));

    String sign = max.substring(0, 1);
    String exponent = max.substring(1, 12); // 11111111110
    String mantissa = max.substring(12, 64);

    System.out.println(sign); // 0 - positive
    System.out.println(exponent); // 2046 - 1023 = 1023
    System.out.println(mantissa); // 0.99999...8

Here's another way without using calc().

// 4 PER ROW
// 100 divided by 4 is 25. Let's use 21% for width, and the remainder 4% for left & right margins...
.child {
  margin: 0 2% 0 2%;
  width: 21%;
}

// 3 PER ROW
// 100 divided by 3 is 33.3333... Let's use 30% for width, and remaining 3.3333% for sides (hint: 3.3333 / 2 = 1.66666)
.child {
  margin: 0 1.66666% 0 1.66666%;
  width: 30%;
}

// and so on!

That's all there is to it. You can get fancy with the dimensions to get a more aesthetic sizes but this is the idea.

check the following things when you interact with facebook graph api.

1) Application connect URL should be the base of your "redirect_uri" connect URL:- www.x-minds.org/fb/connect/ redirect_uri - www.x-minds.org/fb/connect/redirect 2) Your "redirect_uri" should be same in the both case (when you request for a verification code and request for an access_token) redirect_uri - www.x-minds.org/fb/connect/redirect 3) you should encode the the argument when you request for an access_token 4) shouldn't pass the argument (type=client_cred) when you request for an access_token. the authorization server will issue a token without session part. we can't use this token with "me" alias in graph api. This token will have length of (40) but a token with session part will have a length of(81). An access token without session part will work with some cases

eg: -https://graph.facebook.com/?access_token=116122545078207|EyWJJYqrdgQgV1bfueck320z7MM. But Graph API with "me" alias will work with only token with session part.

I was fetching data from backend and updated the screen with just one line of code. It worked. Not sure, why we need to implement Interface. (windows 10, UWP)

    private void populateInCurrentScreen()
    {
        (this.FindName("Dets") as Grid).Visibility = Visibility.Visible;
        this.Bindings.Update();
    }

And for PHP 5.3, you can use this function, which can be embedded in a class or used in procedural style:

run this python code:

import pip
pip.main(['install','flask']) # replace flask with the name of module you want to install

If you need to install multiple modules from a requirements.txt file,

import pip
fo = open("C:/...../requirements.txt", "r")
inp = fo.read()
ls =inp.split()     

for i in ls:
    pip.main(['install',i])

cd to the repository then

find . -name ".git*" -exec rm -R {} \;

Make sure not to accidentally pipe a single dot, slash, asterisk, or other regex wildcard into find, or else rm will happily delete it.

Use a StringWriter instead of a StreamWriter:

public static string SerializeObject<T>(this T toSerialize)
{
    XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType());

    using(StringWriter textWriter = new StringWriter())
    {
        xmlSerializer.Serialize(textWriter, toSerialize);
        return textWriter.ToString();
    }
}

Note, it is important to use toSerialize.GetType() instead of typeof(T) in XmlSerializer constructor: if you use the first one the code covers all possible subclasses of T (which are valid for the method), while using the latter one will fail when passing a type derived from T.    Here is a link with some example code that motivate this statement, with XmlSerializer throwing an Exception when typeof(T) is used, because you pass an instance of a derived type to a method that calls SerializeObject that is defined in the derived type's base class: http://ideone.com/1Z5J1.

Also, Ideone uses Mono to execute code; the actual Exception you would get using the Microsoft .NET runtime has a different Message than the one shown on Ideone, but it fails just the same.

simple just change it to : const uuidv1 = require('uuid'); it will work fine.

Imagine you have a Computer entity, this entity also cannot live without its Software entity and Hardware entity. These form the Computer aggregate, the mini-ecosystem for the Computer portion of the domain.

Aggregate Root is the mothership entity inside the aggregate (in our case Computer), it is a common practice to have your repository only work with the entities that are Aggregate Roots, and this entity is responsible for initializing the other entities.

Consider Aggregate Root as an Entry-Point to an Aggregate.

In C# code:

public class Computer : IEntity, IAggregateRoot
{
    public Hardware Hardware { get; set; }
    public Software Software { get; set; }
}

public class Hardware : IEntity { }
public class Software : IValueObject { }

public class Repository<T> : IRepository<T> where T : IAggregateRoot {}

Keep in mind that Hardware would likely be a ValueObject too (do not have identity on its own), consider it as an example only.

While this seems to work

Code::query()
    ->where('to_be_used_by_user_id', '!=' , 2)
    ->orWhereNull('to_be_used_by_user_id')
    ->get();

you should not use it for big tables, because as a general rule "or" in your where clause is stopping query to use index. You are going from "Key lookup" to "full table scan"

Instead, try Union

$first = Code::whereNull('to_be_used_by_user_id');

$code = Code::where('to_be_used_by_user_id', '!=' , 2)
        ->union($first)
        ->get();

Doing something like

git commit -m"test\ntest"

doesn't work, but something like

git commit -m"$(echo -e "test\ntest")"

works, but it's not very pretty. You set up a git-commitlb command in your PATH which does something like this:

#!/bin/bash

message=$1

git commit -m"$(echo -e "$message")"

And use it like this:

git commitlb "line1\nline2\nline3"

Word of warning, I have a feeling that the general convention is to have a summary line as the first line, and then two line breaks, and then an extended message in the commit message, so doing something like this would break that convention. You could of course do:

git commitlb "line1\n\nline2\nline3"

For a single boxplot:

sb.boxplot(data=Array).set_title('Title')

For more boxplot in the same plot:

import seaborn as sb
sb.boxplot(data=ArrayofArray).set_title('Title')

e.g.

import seaborn as sb
myarray=[78.195229, 59.104538, 19.884109, 25.941648, 72.234825, 82.313911]

Two options I just ran into:

• http://sojo.sourceforge.net/
• http://supercsv.sourceforge.net/

Your code should work, but I'm aware that answer doesn't help you. You can see a working example here (jsfiddle).

Jquery:

$(document).on('click','#test-element',function(){
    alert("You clicked the element with and ID of 'test-element'");
});

As someone already pointed out, you are using an ID instead of a class. If you have more that one element on the page with an ID, then jquery will return only the first element with that ID. There won't be any errors because that's how it works. If this is the problem, then you'll notice that the click event works for the first test-element but not for any that follow.

If this does not accurately describe the symptoms of the problem, then perhaps your selector is wrong. Your update leads me to believe this is the case because of inspecting an element then clicking the page again and triggering the click. What could be causing this is if you put the event listener on the actual document instead of test-element. If so, when you click off the document and back on (like from the developer window back to the document) the event will trigger. If this is the case, you'll also notice the click event is triggered if you click between two different tabs (because they are two different documents and therefore you are clicking the document.

If neither of these are the answer, posting HTML will go a long way toward figuring it out.

I'm asked this question very frequently, if it's smart to use "Share project..." if a eclipse project has been disconnected from it SVN counterpart in the repository. So, I append my answer to this thread.

The SVN-Team option "Share project ..." is totally fine for projects that exist in SVN and in your Eclipse workspace, even if the Eclipse project is missing the hidden .svn configuration. You can still connect them. Eclipse SVN-implementation (Subclipse/Subversive) will verify if the provided SVN http(s) source is populated. If yes, all existing files will be copied and linked (checked out in SVN terms) to your very personal Eclipse workspace.

Word of caution:

• Do a backup if you depend on you local files. The SVN implementation may vary its behaviour with every release.
• If you have multiple projects encapsulated within each other, make sure you point the SVN path to the correct local path.

regards, Feder

Run a jar file and specify a class path like this:

java -cp <jar_name.jar:libs/*> com.test.App

jar_name.jar is the full name of the JAR you want to execute

libs/* is a path to your dependency JARs

com.test.App is the fully qualified name of the class from the JAR that has the main(String[]) method

The jar and dependent jar should have execute permissions.

You can also use your own timing mechanisms if you want a little more control, but possibly less accuracy and more code/complexity, but I would still recommend a timer. Use this though if you need to have control over the actual timing thread:

private void ThreadLoop(object callback)
{
    while(true)
    {
        ((Delegate) callback).DynamicInvoke(null);
        Thread.Sleep(5000);
    }
}

would be your timing thread(modify this to stop when reqiuired, and at whatever time interval you want).

and to use/start you can do:

Thread t = new Thread(new ParameterizedThreadStart(ThreadLoop));

t.Start((Action)CallBack);

Callback is your void parameterless method that you want called at each interval. For example:

private void CallBack()
{
    //Do Something.
}

Performance Analysis For loops performs faster than map or foreach as number of elements in a array increases.

let array = [];
for (var i = 0; i < 20000000; i++) {
  array.push(i)
}

console.time('map');
array.map(num => {
  return num * 4;
});
console.timeEnd('map');


console.time('forEach');
array.forEach((num, index) => {
  return array[index] = num * 4;
});
console.timeEnd('forEach');

console.time('for');
for (i = 0; i < array.length; i++) {
  array[i] = array[i] * 2;

}
console.timeEnd('for');

NewValue = (((OldValue - OldMin) * (NewMax - NewMin)) / (OldMax - OldMin)) + NewMin

Or a little more readable:

OldRange = (OldMax - OldMin)  
NewRange = (NewMax - NewMin)  
NewValue = (((OldValue - OldMin) * NewRange) / OldRange) + NewMin

Or if you want to protect for the case where the old range is 0 (OldMin = OldMax):

OldRange = (OldMax - OldMin)
if (OldRange == 0)
    NewValue = NewMin
else
{
    NewRange = (NewMax - NewMin)  
    NewValue = (((OldValue - OldMin) * NewRange) / OldRange) + NewMin
}

Note that in this case we're forced to pick one of the possible new range values arbitrarily. Depending on context, sensible choices could be: NewMin (see sample), NewMax or (NewMin + NewMax) / 2

The function supports the dry principle - ensuring that you don't hard code urls throughout your app. A url should be defined in one place, and only one place - your url conf. After that you're really just referencing that info.

Use reverse() to give you the url of a page, given either the path to the view, or the page_name parameter from your url conf. You would use it in cases where it doesn't make sense to do it in the template with {% url 'my-page' %}.

There are lots of possible places you might use this functionality. One place I've found I use it is when redirecting users in a view (often after the successful processing of a form)-

return HttpResponseRedirect(reverse('thanks-we-got-your-form-page'))

You might also use it when writing template tags.

Another time I used reverse() was with model inheritance. I had a ListView on a parent model, but wanted to get from any one of those parent objects to the DetailView of it's associated child object. I attached a get__child_url() function to the parent which identified the existence of a child and returned the url of it's DetailView using reverse().

$num += (6-$num%6)%6;

no need for a while loop! Modulo (%) returns the remainder of a division. IE 20%6 = 2. 6-2 = 4. 20+4 = 24. 24 is divisible by 6.

Compress and Send Bitmap

The accepted answer will crash when the Bitmap is too large. I believe it's a 1MB limit. The Bitmap must be compressed into a different file format such as a JPG represented by a ByteArray, then it can be safely passed via an Intent.

Implementation

The function is contained in a separate thread using Kotlin Coroutines because the Bitmap compression is chained after the Bitmap is created from an url String. The Bitmap creation requires a separate thread in order to avoid Application Not Responding (ANR) errors.

Concepts Used

• Kotlin Coroutines notes.
• The Loading, Content, Error (LCE) pattern is used below. If interested you can learn more about it in this talk and video.
• LiveData is used to return the data. I've compiled my favorite LiveData resource in these notes.
• In Step 3, toBitmap() is a Kotlin extension function requiring that library to be added to the app dependencies.

Code

1. Compress Bitmap to JPG ByteArray after it has been created.

Repository.kt

suspend fun bitmapToByteArray(url: String) = withContext(Dispatchers.IO) {
    MutableLiveData<Lce<ContentResult.ContentBitmap>>().apply {
        postValue(Lce.Loading())
        postValue(Lce.Content(ContentResult.ContentBitmap(
            ByteArrayOutputStream().apply {
                try {                     
                    BitmapFactory.decodeStream(URL(url).openConnection().apply {
                        doInput = true
                        connect()
                    }.getInputStream())
                } catch (e: IOException) {
                   postValue(Lce.Error(ContentResult.ContentBitmap(ByteArray(0), "bitmapToByteArray error or null - ${e.localizedMessage}")))
                   null
                }?.compress(CompressFormat.JPEG, BITMAP_COMPRESSION_QUALITY, this)
           }.toByteArray(), "")))
        }
    }

ViewModel.kt

//Calls bitmapToByteArray from the Repository
private fun bitmapToByteArray(url: String) = liveData {
    emitSource(switchMap(repository.bitmapToByteArray(url)) { lce ->
        when (lce) {
            is Lce.Loading -> liveData {}
            is Lce.Content -> liveData {
                emit(Event(ContentResult.ContentBitmap(lce.packet.image, lce.packet.errorMessage)))
            }
            is Lce.Error -> liveData {
                Crashlytics.log(Log.WARN, LOG_TAG,
                        "bitmapToByteArray error or null - ${lce.packet.errorMessage}")
            }
        }
    })
}

2. Pass image as ByteArray via an Intent.

In this sample it's passed from a Fragment to a Service. It's the same concept if being shared between two Activities.

Fragment.kt

ContextCompat.startForegroundService(
    context!!,
    Intent(context, AudioService::class.java).apply {
        action = CONTENT_SELECTED_ACTION
        putExtra(CONTENT_SELECTED_BITMAP_KEY, contentPlayer.image)
    })

3. Convert ByteArray back to Bitmap.

Utils.kt

fun ByteArray.byteArrayToBitmap(context: Context) =
    run {
        BitmapFactory.decodeByteArray(this, BITMAP_OFFSET, size).run {
            if (this != null) this
            // In case the Bitmap loaded was empty or there is an error I have a default Bitmap to return.
            else AppCompatResources.getDrawable(context, ic_coinverse_48dp)?.toBitmap()
        }
    }

In Xcode 9 and Swift 4:

Print exception stack to know the reason of the exception:

1. Go to show break point navigator.

2. Add (+) Add Exception Breakpoint.

3. Select the new breakpoint, Control-Click, Edit Breakpoint.

4. Add Action and Enter: po $arg1

When learning a new language, there are some nice problem sets you can use to learn the language better.

• Project Euler has some nice problems with a strong mathematical twist.
• Practice on Google Code Jam past problems, stick to the qualification rounds for the easier problems

_ has 3 main conventional uses in Python:

1. To hold the result of the last executed expression(/statement) in an interactive interpreter session (see docs). This precedent was set by the standard CPython interpreter, and other interpreters have followed suit

2. For translation lookup in i18n (see the gettext documentation for example), as in code like

   raise forms.ValidationError(_("Please enter a correct username"))
   

3. As a general purpose "throwaway" variable name:

   1. To indicate that part of a function result is being deliberately ignored (Conceptually, it is being discarded.), as in code like:

      label, has_label, _ = text.partition(':')
      

   2. As part of a function definition (using either def or lambda), where the signature is fixed (e.g. by a callback or parent class API), but this particular function implementation doesn't need all of the parameters, as in code like:

      def callback(_):
          return True
      

      [For a long time this answer didn't list this use case, but it came up often enough, as noted here, to be worth listing explicitly.]

   This use case can conflict with the translation lookup use case, so it is necessary to avoid using _ as a throwaway variable in any code block that also uses it for i18n translation (many folks prefer a double-underscore, __, as their throwaway variable for exactly this reason).

   Linters often recognize this use case. For example year, month, day = date() will raise a lint warning if day is not used later in the code. The fix, if day is truly not needed, is to write year, month, _ = date(). Same with lambda functions, lambda arg: 1.0 creates a function requiring one argument but not using it, which will be caught by lint. The fix is to write lambda _: 1.0. An unused variable is often hiding a bug/typo (e.g. set day but use dya in the next line).

I used the following:

import matplotlib.pyplot as plt

p1 = plt.plot(dates, temp, 'r-', label="Temperature (celsius)")  
p2 = plt.plot(dates, psal, 'b-', label="Salinity (psu)")  
plt.legend(loc='upper center', numpoints=1, bbox_to_anchor=(0.5, -0.05),        ncol=2, fancybox=True, shadow=True)

plt.savefig('data.png')  
plt.show()  
f.close()
plt.close()

I found very important to use plt.show after saving the figure, otherwise it won't work.figure exported in png

Something like this should work: From Frans Bouma's Blog

SELECT * FROM
(
    SELECT a.*, rownum r__
    FROM
    (
        SELECT * FROM ORDERS WHERE CustomerID LIKE 'A%'
        ORDER BY OrderDate DESC, ShippingDate DESC
    ) a
    WHERE rownum < ((pageNumber * pageSize) + 1 )
)
WHERE r__ >= (((pageNumber-1) * pageSize) + 1)

STRING TO URI.

Uri uri=Uri.parse("YourString");

URI TO STRING

Uri uri;
String andro=uri.toString();

use groupby and filter

import pandas as pd
df = pd.DataFrame({"A":["foo", "foo", "foo", "bar"], "B":[0,1,1,1], "C":["A","A","B","A"]})
df.groupby(["A", "C"]).filter(lambda df:df.shape[0] == 1)

Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). If you have normal distribution with mean and std (which is sqr(var)) and you want to calculate:

from scipy.stats import norm

# cdf(x < val)
print norm.cdf(val, m, s)

# cdf(x > val)
print 1 - norm.cdf(val, m, s)

# cdf(v1 < x < v2)
print norm.cdf(v2, m, s) - norm.cdf(v1, m, s)

Read more about cdf here and scipy implementation of normal distribution with many formulas here.

That's the other way around. You should write:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    click: function() {
        // Handle click...
    }
}, "td");

This worked for me:

select * from mytable
where array_to_string(pub_types, ',') like '%Journal%'

Depending on your normalization needs, it might be better to implement a separate table with a FK reference as you may get better performance and manageability.

Try to use strstr

char* lastSlash;
lastSlash = strstr(filename, ".");

Use git clean

when I create my JLabel and enter the text to it, there is no wordwrap or anything

HTML formatting can be used to cause word wrap in any Swing component that offers styled text. E.G. as demonstrated in this answer.

I wanted to be able to take a function name as a string, call it, AND pass an argument to the function. I couldn't get the selected answer for this question to do that, but this answer explained it exactly, and here is a short demo.

function test_function(argument)    {
    alert('This function ' + argument); 
}

functionName = 'test_function';

window[functionName]('works!');

This also works with multiple arguments.

I might consider using a dict and re.sub for something like this:

import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
    return repldict[match.group(0)]

regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
    for line in fin:
        fout.write(regex.sub(replfunc,line))

This has a slight advantage to replace in that it is a bit more robust to overlapping matches.

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()):

entryList.forEach(e->e.setTempId(tempId));

List<Entry> updatedEntries = entryList.stream()
  .map(e->entityManager.update(entry, entry.getId()))
  .collect(toList());

Words in a text are always a source of randomness. Given a certain word, nothing can be inferred about the next word. For each word, we can take the ASCII codes of its letters, add those codes to form a number. The parity of this number is a good candidate for a random boolean.

Possible drawbacks:

1. this strategy is based upon using a text file as a source for the words. At some point, the end of the file will be reached. However, you can estimate how many times you are expected to call the randomBoolean() function from your app. If you will need to call it about 1 million times, then a text file with 1 million words will be enough. As a correction, you can use a stream of data from a live source like an online newspaper.

2. using some statistical analysis of the common phrases and idioms in a language, one can estimate the next word in a phrase, given the first words of the phrase, with some degree of accuracy. But statistically, these cases are rare, when we can accuratelly predict the next word. So, in most cases, the next word is independent on the previous words.

In Eclipse, in the root of my project, there is a file called 'the_comedy_of_errors' (no extension) - created with File> New > File , where I pasted some content from here: http://shakespeare.mit.edu/comedy_errors/comedy_errors.1.1.html

As a workaround, you could use the timestamp (old and new) for checking though, that one is not updated when there are no changes to the row. (Possibly that is the source for confusion? Because that one is also called 'on update' but is not executed when no change occurs) Changes within one second will then not execute that part of the trigger, but in some cases that could be fine (like when you have an application that rejects fast changes anyway.)

For example, rather than

IF NEW.a <> OLD.a or NEW.b <> OLD.b /* etc, all the way to NEW.z <> OLD.z */ 
THEN  
  INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF

you could use

IF NEW.ts <> OLD.ts 
THEN  
  INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF

Then you don't have to change your trigger every time you update the scheme (the issue you mentioned in the question.)

EDIT: Added full example

create table foo (a INT, b INT, ts TIMESTAMP);
create table bar (a INT, b INT);

INSERT INTO foo (a,b) VALUES(1,1);
INSERT INTO foo (a,b) VALUES(2,2);
INSERT INTO foo (a,b) VALUES(3,3);

It is working because of mysql's behavior on handling timestamps. The time stamp is only updated if a change occured in the updates.

If the header file is /usr/include/sdl/SDL.h and your code has:

#include "SDL.h"

You need to either fix your code:

#include "sdl/SDL.h"

Or tell the preprocessor where to find include files:

CFLAGS = ... -I/usr/include/sdl ...

The easiest solution is to simply style the element you're inserting the text into with the following CSS property:

white-space: pre-wrap;

This property causes whitespace and newlines within the matching elements to be treated in the same way as inside a <textarea>. That is, consecutive whitespace is not collapsed, and lines are broken at explicit newlines (but are also wrapped automatically if they exceed the width of the element).

Given that several of the answers posted here so far have been vulnerable to HTML injection (e.g. because they assign unescaped user input to innerHTML) or otherwise buggy, let me give an example of how to do this safely and correctly, based on your original code:

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.append(postText);_x000D_
  var card = document.createElement('div');_x000D_
  card.append(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.prepend(card);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
  white-space: pre-wrap;  /* <-- THIS PRESERVES THE LINE BREAKS */_x000D_
}_x000D_
textarea {_x000D_
  width: 100%;_x000D_
}

<textarea id="post-text" class="form-control" rows="8" placeholder="What's up?" required>Group Schedule:_x000D_
_x000D_
Tuesday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Thursday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Sunday practice @ (9pm - 12 am)</textarea><br>_x000D_
<input type="button" id="post-button" value="Post!">_x000D_
<div id="card-stack"></div>

Note that, like your original code, the snippet above uses append() and prepend(). As of this writing, those functions are still considered experimental and not fully supported by all browsers. If you want to be safe and remain compatible with older browsers, you can substitute them pretty easily as follows:

• element.append(otherElement) can be replaced with element.appendChild(otherElement);
• element.prepend(otherElement) can be replaced with element.insertBefore(otherElement, element.firstChild);
• element.append(stringOfText) can be replaced with element.appendChild(document.createTextNode(stringOfText));
• element.prepend(stringOfText) can be replaced with element.insertBefore(document.createTextNode(stringOfText), element.firstChild);
• as a special case, if element is empty, both element.append(stringOfText) and element.prepend(stringOfText) can simply be replaced with element.textContent = stringOfText.

Here's the same snippet as above, but without using append() or prepend():

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.insertBefore(card, cardStack.firstChild);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
  white-space: pre-wrap;  /* <-- THIS PRESERVES THE LINE BREAKS */_x000D_
}_x000D_
textarea {_x000D_
  width: 100%;_x000D_
}

<textarea id="post-text" class="form-control" rows="8" placeholder="What's up?" required>Group Schedule:_x000D_
_x000D_
Tuesday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Thursday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Sunday practice @ (9pm - 12 am)</textarea><br>_x000D_
<input type="button" id="post-button" value="Post!">_x000D_
<div id="card-stack"></div>

Ps. If you really want to do this without using the CSS white-space property, an alternative solution would be to explicitly replace any newline characters in the text with <br> HTML tags. The tricky part is that, to avoid introducing subtle bugs and potential security holes, you have to first escape any HTML metacharacters (at a minimum, & and <) in the text before you do this replacement.

Probably the simplest and safest way to do that is to let the browser handle the HTML-escaping for you, like this:

var post = document.createElement('p');
post.textContent = postText;
post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');

document.getElementById('post-button').addEventListener('click', function () {_x000D_
  var post = document.createElement('p');_x000D_
  var postText = document.getElementById('post-text').value;_x000D_
  post.textContent = postText;_x000D_
  post.innerHTML = post.innerHTML.replace(/\n/g, '<br>\n');  // <-- THIS FIXES THE LINE BREAKS_x000D_
  var card = document.createElement('div');_x000D_
  card.appendChild(post);_x000D_
  var cardStack = document.getElementById('card-stack');_x000D_
  cardStack.insertBefore(card, cardStack.firstChild);_x000D_
});

#card-stack p {_x000D_
  background: #ddd;_x000D_
}_x000D_
textarea {_x000D_
  width: 100%;_x000D_
}

<textarea id="post-text" class="form-control" rows="8" placeholder="What's up?" required>Group Schedule:_x000D_
_x000D_
Tuesday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Thursday practice @ 5th floor (8pm - 11 pm)_x000D_
_x000D_
Sunday practice @ (9pm - 12 am)</textarea><br>_x000D_
<input type="button" id="post-button" value="Post!">_x000D_
<div id="card-stack"></div>

Note that, while this will fix the line breaks, it won't prevent consecutive whitespace from being collapsed by the HTML renderer. It's possible to (sort of) emulate that by replacing some of the whitespace in the text with non-breaking spaces, but honestly, that's getting rather complicated for something that can be trivially solved with a single line of CSS.

This working fine for me.

I believe telnet 74.255.12.25 8089 . Why don't u try both

Vim's <leader> key is a way of creating a namespace for commands you want to define. Vim already maps most keys and combinations of Ctrl + (some key), so <leader>(some key) is where you (or plugins) can add custom behavior.

For example, if you find yourself frequently deleting exactly 3 words and 7 characters, you might find it convenient to map a command via nmap <leader>d 3dw7x so that pressing the leader key followed by d will delete 3 words and 7 characters. Because it uses the leader key as a prefix, you can be (relatively) assured that you're not stomping on any pre-existing behavior.

The default key for <leader> is \, but you can use the command :let mapleader = "," to remap it to another key (, in this case).

Usevim's page on the leader key has more information.

XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);

For information purpose, _timestamp is now deprecated since 2.0.0-beta2. Use date type in your mapping.

A simple date mapping JSON from date datatype doc:

{
  "mappings": {
     "my_type": {
        "properties": {
          "date": {
          "type": "date" 
        }
      }
    }
  }
}

You can also add a format field in date:

{
  "mappings": {
    "my_type": {
      "properties": {
        "date": {
          "type":   "date",
          "format": "yyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
        }
      }
    }
  }
}

Well, I made a simple two liner script for this, Its small and does what u want.

Check it http://jsfiddle.net/9RxLM/

Its a jquery solution :D

Simply type the table name and select it and press ATL + F1

Say your table name is Customer then open a new query window, type and select the table name and press ALT + F1

It will show the complete definition of table.

I recorded a macro making a hiperlink. This resulted.

ActiveCell.FormulaR1C1 = "=HYPERLINK(""[Workbook.xlsx]Sheet1!A1"",""CLICK HERE"")"

String value = someMethod();
switch(0) {
default:
    if ("apple".equals(value)) {
        method1();
        break;
    }
    if ("carrot".equals(value)) {
        method2();
        break;
    }
    if ("mango".equals(value)) {
        method3();
        break;
    }
    if ("orance".equals(value)) {
        method4();
        break;
    }
}

If you insert ng-click="$event.stopPropagation" on the parent element of your template, the stopPropogation will be caught as it bubbles up the tree, so you only have to write it once for your entire template.

Give Icomoon a try. You can upload your own SVGs, add them to the library, then create a custom font combining FontAwesome with your own icons.

To add on to what Alisson said you could check to see if a row is returned.

// Query stuff ...
$query = $this->db->get();

if ($query->num_rows() > 0)
{
    $row = $query->row(); 
    return $row->campaign_id;
}

return null; // or whatever value you want to return for no rows found

There is one example where in actually kills your performance.

If you use in on a O(1) container that only implements __getitem__ and has_key() but not __contains__ you will turn an O(1) search into an O(N) search (as in falls back to a linear search via __getitem__).

Fix is obviously trivial:

def __contains__(self, x):
    return self.has_key(x)

Try this:

function welcomeMessage()
{
    var shape1 = new Shape();
    //alert(shape1.draw());
    alert(shape1.hasOwnProperty("name"));
}

When working with reflection in JavaScript, member objects are always refered to as the name as a string. For example:

for(i in obj) { ... }

The loop iterator i will be hold a string value with the name of the property. To use that in code you have to address the property using the array operator like this:

 for(i in obj) {
   alert("The value of obj." + i + " = " + obj[i]);
 }

Free "Export to KML" script for ArcGIS 9

Here is a list of available methods that someone found.

Also, it seems to me that the most efficient representation of a polygon layer is by using Google Maps API's polyline encoding, which significantly compresses lat-lng data. But getting into that format takes work: use ArcMap to export Shape as lat/lng coordinates, then convert into polylines using Google Maps API.

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.
