It's possible to set the center aligned view as an anchor for other views. In the example below "@+id/stat_2" centered horizontally in parent and it serves as an anchor for other views in this layout.

Here's how it works on smallest smartphone (3.7 480x800 Nexus One) vs largest smartphone (5.5 1440x2560 Pixel XL)

You should be able to create a query with this filter here:

(&(objectClass=user)(sAMAccountName=yourUserName)
  (memberof=CN=YourGroup,OU=Users,DC=YourDomain,DC=com))

and when you run that against your LDAP server, if you get a result, your user "yourUserName" is indeed a member of the group "CN=YourGroup,OU=Users,DC=YourDomain,DC=com

Try and see if this works!

If you use C# / VB.Net and System.DirectoryServices, this snippet should do the trick:

DirectoryEntry rootEntry = new DirectoryEntry("LDAP://dc=yourcompany,dc=com");

DirectorySearcher srch = new DirectorySearcher(rootEntry);
srch.SearchScope = SearchScope.Subtree;

srch.Filter = "(&(objectClass=user)(sAMAccountName=yourusername)(memberOf=CN=yourgroup,OU=yourOU,DC=yourcompany,DC=com))";

SearchResultCollection res = srch.FindAll();

if(res == null || res.Count <= 0) {
    Console.WriteLine("This user is *NOT* member of that group");
} else {
    Console.WriteLine("This user is INDEED a member of that group");
}

Word of caution: this will only test for immediate group memberships, and it will not test for membership in what is called the "primary group" (usually "cn=Users") in your domain. It does not handle nested memberships, e.g. User A is member of Group A which is member of Group B - that fact that User A is really a member of Group B as well doesn't get reflected here.

alternative solution for this with using many infowindows: save prev opened infowindow in a variable and then close it when new window opened

var prev_infowindow =false; 
...
base.attachInfo = function(marker, i){
    var infowindow = new google.maps.InfoWindow({
        content: 'yourmarkerinfocontent'
    });

    google.maps.event.addListener(marker, 'click', function(){
        if( prev_infowindow ) {
           prev_infowindow.close();
        }

        prev_infowindow = infowindow;
        infowindow.open(base.map, marker);
    });
}

As long as you have unique integers (or some unique value) in the current PK, you could create a new table, and insert into it with IDENTITY INSERT ON. Then drop the old table, and rename the new table.

Don't forget to recreate any indexes.

Use a stored procedure:

EDIT: A complement for serialize List (or anything else):

List<string> testList = new List<int>();

testList.Add(1);
testList.Add(2);
testList.Add(3);

XmlSerializer xs = new XmlSerializer(typeof(List<int>));
MemoryStream ms = new MemoryStream();
xs.Serialize(ms, testList);

string resultXML = UTF8Encoding.UTF8.GetString(ms.ToArray());

The result (ready to use with XML parameter):

<?xml version="1.0"?>
<ArrayOfInt xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <int>1</int>
  <int>2</int>
  <int>3</int>
</ArrayOfInt>

For The Rest Of Us

Here is a simple and clear example of how this works

Regex: ([a-zA-Z0-9]+)([\s]+)([a-zA-Z ]+)([\s]+)([0-9]+)

String: "!* UserName10 John Smith 01123 *!"

group(0): UserName10 John Smith 01123
group(1): UserName10
group(2):  
group(3): John Smith
group(4):  
group(5): 01123

As you can see, I have created FIVE groups which are each enclosed in parentheses.

I included the !* and *! on either side to make it clearer. Note that none of those characters are in the RegEx and therefore will not be produced in the results. Group(0) merely gives you the entire matched string (all of my search criteria in one single line). Group 1 stops right before the first space because the space character was not included in the search criteria. Groups 2 and 4 are simply the white space, which in this case is literally a space character, but could also be a tab or a line feed etc. Group 3 includes the space because I put it in the search criteria ... etc.

Hope this makes sense.

On Windows and Linux, press Ctrl+K, then release the keys and press O (the letter O, not Zero).

On macOS, press command+K, then O (without holding command).

This will open the active file tab in a new window/instance.

Trust store generally (actually should only contain root CAs but this rule is violated in general) contains the certificates that of the root CAs (public CAs or private CAs). You can verify the list of certs in trust store using

keytool -list -v -keystore truststore.jks

class CallByName():
    
    def method1(self):
        pass

    def method2(self):
        pass

    def method3(self):
        pass

    def get_method(self, method_name):
        method = getattr(self, method_name)
        return method()


callbyname = CallByName()
method1 = callbyname.get_method(method_name)

```

You can use join method from android.text.TextUtils class like:

TextUtils.join("",array);

While getting the permanent access token I followed above 5 steps as Donut mentioned. However in the 5th step while generating permanent access token its returning the long lived access token(Which is valid for 2 months) not permanent access token(which never expires). what I noticed is the current version of Graph API is V2.5. If you trying to get the permanent access token with V2.5 its giving long lived access token.Try to make API call with V2.2(if you are not able to change version in the graph api explorer,hit the API call https://graph.facebook.com/v2.2/{account_id}/accounts?access_token={long_lived_access_token} in the new tab with V2.2) then you will get the permanent access token(Which never expires)

There is no $contains operator in mongodb.

You can use the answer from JohnnyHK as that works. The closest analogy to contains that mongo has is $in, using this your query would look like:

PersonModel.find({ favouriteFoods: { "$in" : ["sushi"]} }, ...);

The fsevents warnings are gone (on Linux).

Even the latest yarn (2.x) shows the warnings.

I was befuddled by the same darn issue. I tried to remove and and the global.asax (closed VS2010 before adding). Cleaned the project/solution, checked for any changes in the web application configuration and other stuffs that had worked for other people here in SO threads. I finally cleaned the solution, deleted the bin/obj folders and stopped any running VS2010 development servers then I reverted all the changes back and found the application was running again. I redid the same things and now its working fine.

Happened again and this time this solution worked for me.

Ambu,

I was having the same issue as you, and this is the code I used to figure it out. Although, I don't use the footer row section for my purposes, I did include it in this code.

    DataTable dt = new DataTable();

    // add the columns to the datatable            
    if (GridView1.HeaderRow != null)
    {

        for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
        {
            dt.Columns.Add(GridView1.HeaderRow.Cells[i].Text);
        }
    }

    //  add each of the data rows to the table
    foreach (GridViewRow row in GridView1.Rows)
    {
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < row.Cells.Count; i++)
        {
            dr[i] = row.Cells[i].Text.Replace("&nbsp;","");
        }
        dt.Rows.Add(dr);
    }

    //  add the footer row to the table
    if (GridView1.FooterRow != null)
    {
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < GridView1.FooterRow.Cells.Count; i++)
        {
            dr[i] = GridView1.FooterRow.Cells[i].Text.Replace("&nbsp;","");
        }
        dt.Rows.Add(dr);
    }

Variables (something) are not valid JSON, verify using http://jsonlint.com/

Simply put, don't use DateTime.MinVaue as a default value.

There are a couple of different MinValues out there, depending which environment you are in.

I once had a project, where I was implementing a Windows CE project, I was using the Framework's DateTime.MinValue (year 0001), the database MinValue (1753) and a UI control DateTimePicker (i think it was 1970). So there were at least 3 different MinValues that were leading to strange behavior and unexpected results. (And I believe that there was even a fourth (!) version, I just do not recall where it came from.).

Use a nullable database field and change your value into a Nullable<DateTime> instead. Where there is no valid value in your code, there should not be a value in the database as well. :-)

In the URL you pointed to, the button_text.xml is being used to set the textColor attribute.That it is reason they had the button_text.xml in res/color folder and therefore they used @color/button_text.xml

But you are trying to use it for background attribute. The background attribute looks for something in res/drawable folder.

check this i got this selector custom button from the internet.I dont have the link.but i thank the poster for this.It helped me.have this in the drawable folder

It has to be made clear the HTTP protocol is synchronous and this has nothing to do with the programming language. Client sends a request and gets a synchronous response.

If you want to an asynchronous behavior over HTTP, this has to be built over HTTP (I don't know anything about ActionScript but I suppose that this is what the ActionScript does too). There are many libraries that could give you such functionality (e.g. Jersey SSE). Note that they do somehow define dependencies between the client and the server as they do have to agree on the exact non standard communication method above HTTP.

If you cannot control both the client and the server or if you don't want to have dependencies between them, the most common approach of implementing asynchronous (e.g. event based) communication over HTTP is using the webhooks approach (you can check this for an example implementation in java).

Hope I helped!

To install PDT (PHP Development Tools) for PHP development environment is better in Eclipse. The following are the steps to install PDT in Eclipse (I'm considering version 3.7 (Indigo)):

1. Open Eclipse (in my case Eclipse Indigo).
2. Go to Help --> Install New Software...
3. Expand the "Work with" drop down and select "Indigo - http://download.eclipse.org/releases/indigo".
4. Expand "Programming Languages" from the list.
5. Check PHP Development Tools (PDT) SDK Feature.
6. Click "Next >" at the bottom and follow the further instruction of Eclipse.
7. After successful installation of PDT: Go to Window --> Preferences and see the list as PHP at left panel.

In Java:

    String regex = "[^-\\s]";

    System.out.println("-".matches(regex)); // prints "false"
    System.out.println(" ".matches(regex)); // prints "false"
    System.out.println("+".matches(regex)); // prints "true"

The regex [^-\s] works as expected. [^\s-] also works.

    The hyphen can be included right after the opening bracket, or right before the closing bracket, or right after the negating caret.

I got the same error.

I was refering a VS2010 DLL in a VS2012 project.

Just recompiled the DLL on VS2012 and now everything is fine.

If you haven't commit the local changes yet since the last pull/clone, you can use:

git checkout *
git pull

checkout will clear your local changes with the last local commit, and pull will sincronize it to the remote repository

on the form2.buttonclick put

this.close();

form1 should have object of form2.

you need to subscribe Closing event of form2.

and in closing method put

this.close();

If you want search for printable strings, you can use:

strings -ao filename | grep string

strings will output all printable strings from a binary with offsets, and grep will search within.

If you want search for any binary string, here is your friend:

You'll normally be returning JSON either because:

A) You are building part / all of your application as a Single Page Application (SPA) and you need your client-side JavaScript to be able to pull in additional data without fully reloading the page.

or

B) You are building an API that third parties will be consuming and you have decided to use JSON to serialize your data.

_{Or, possibly, you are eating your own dogfood and doing both}

In both cases render :json => some_data will JSON-ify the provided data. The :callback key in the second example needs a bit more explaining (see below), but it is another variation on the same idea (returning data in a way that JavaScript can easily handle.)

Why :callback?

JSONP (the second example) is a way of getting around the Same Origin Policy that is part of every browser's built-in security. If you have your API at api.yoursite.com and you will be serving your application off of services.yoursite.com your JavaScript will not (by default) be able to make XMLHttpRequest (XHR - aka ajax) requests from services to api. The way people have been sneaking around that limitation (before the Cross-Origin Resource Sharing spec was finalized) is by sending the JSON data over from the server as if it was JavaScript instead of JSON). Thus, rather than sending back:

{"name": "John", "age": 45}

the server instead would send back:

valueOfCallbackHere({"name": "John", "age": 45})

Thus, a client-side JS application could create a script tag pointing at api.yoursite.com/your/endpoint?name=John and have the valueOfCallbackHere function (which would have to be defined in the client-side JS) called with the data from this other origin.)

The problem is that readlines is a list of strings, each of which is a line of filename. Perhaps you meant:

for line in readlines:
    Type = line.split(",")
    x = Type[1]
    y = Type[2]
    print(x,y)

I tried this, but the query won't run telling me my field is invalid in the select statement because it is not contained in either an aggregate function or the GROUP BY clause. It's forcing me to keep it there. Is there a way around this?

You need to do a self-join. You can't both aggregate and preserve non-aggregated data in the same subquery. E.g.

select q2.AccountNumber, q2.Bill, q2.BillDate, q1.BillSum
from
(
SELECT AccountNumber, SUM(Bill) as BillSum
FROM Table1
GROUP BY AccountNumber
) q1,
(
select AccountNumber, Bill, BillDate
from table1
) q2
where q1.AccountNumber = q2.AccountNumber

You can write different sheets as follows

$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("creater");
$objPHPExcel->getProperties()->setLastModifiedBy("Middle field");
$objPHPExcel->getProperties()->setSubject("Subject");
$objWorkSheet = $objPHPExcel->createSheet();
$work_sheet_count=3;//number of sheets you want to create
$work_sheet=0;
while($work_sheet<=$work_sheet_count){ 
     if($work_sheet==0){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 1')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     if($work_sheet==1){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 2')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed

You can also check out examples in TensorFlow/skflow, which offers save and restore methods that can help you easily manage your models. It has parameters that you can also control how frequently you want to back up your model.

Imagine you have a numpy array of integers (it works with other types but you need some slight modification). You can do this:

a = np.array([0, 3, 5])
a_str = ','.join(str(x) for x in a) # '0,3,5'
a2 = np.array([int(x) for x in a_str.split(',')]) # np.array([0, 3, 5])

If you have an array of float, be sure to replace int by float in the last line.

You can also use the __repr__() method, which will have the advantage to work for multi-dimensional arrays:

from numpy import array
numpy.set_printoptions(threshold=numpy.nan)
a = array([[0,3,5],[2,3,4]])
a_str = a.__repr__() # 'array([[0, 3, 5],\n       [2, 3, 4]])'
a2 = eval(a_str) # array([[0, 3, 5],
                 #        [2, 3, 4]])

A catch-block in a try statement needs to catch exactly the exception that the code inside the try {}-block can throw (or a super class of that).

try {
    //do something that throws ExceptionA, e.g.
    throw new ExceptionA("I am Exception Alpha!");
}
catch(ExceptionA e) {
    //do something to handle the exception, e.g.
    System.out.println("Message: " + e.getMessage());
}

What you are trying to do is this:

try {
    throw new ExceptionB("I am Exception Bravo!");
}
catch(ExceptionA e) {
    System.out.println("Message: " + e.getMessage());
}

This will lead to an compiler error, because your java knows that you are trying to catch an exception that will NEVER EVER EVER occur. Thus you would get: exception ExceptionA is never thrown in body of corresponding try statement.

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

You would have to turn your font into a web font as shown in these SO questions:

• Non-Standard fonts in web?
• How to add some non-standard font to a website?

However, you may run into copyright issues with this: Not every font allows distribution as a web font. Check your font license to see whether it is allowed.

One of the easiest free and legal ways to use web fonts is Google Web Fonts. However, sadly, they don't have Helvetica Neue in their portfolio.

One of the easiest non-free and legal ways is to purchase the font from a foundry that offers web licenses. I happen to know that the myFonts foundry does this; they even give you a full package with all the JavaScript and CSS pre-prepared. I'm sure other foundries do the same.

Edit: MyFonts have Helvetica neue in Stock, but apparently not with a web license. Check out this list of similar fonts of which some have a web license. Also, Ray Larabie has some nice fonts there, with web licenses, some of them are free.

I'm trying to find a way to scan my entire Linux system for all files containing a specific string of text. ... Is this close to the proper way to do it? If not, how should I? ... This ability to find text strings in files would be extraordinarily useful for some programming projects I'm doing.

While you should never replace (or alias) a system command with a different program, due to risk of mysterious breakage of scripts or other utilities, if you are running a text search manually or from your own scripts or programs you should consider the fastest suitable program when searching a large number of files a number of times. Ten minutes to half an hour time spent installing and familiarizing yourself with a better utility can be recovered after a few uses for the use-case you described.

A webpage offering a "Feature comparison of ack, ag, git-grep, GNU grep and ripgrep" can assist you to decide which program offers the features you need.

• Andrew Gallant's Blog claims: "ripgrep is faster than {grep, ag, git grep, ucg, pt, sift}" (a claim shared by some of the others, this is why a feature comparison is helpful). Of particular interest is his section on regex implementations and pitfalls.

  The following command searches all files, including hidden and executable:

  $ rg -uuu foobar

• The Silver Searcher (ag) claims it is 5-10x faster than Ack. This program is suggested in some other answers. The GitHub doesn't appear as recent as ripgrep's and there are noticably more commits and branches with fewer releases, it's hard to draw an absolute claim based on those stats. The short version: ripgrep is faster, but there's a tiny learning curve to not get caught by the differences.

• So what could be next, you guessed it, the platinum searcher. The claims are: it searches code about 3–5× faster than ack, but its speed is equal to the silver searcher. It's written in GoLang and searches UTF-8, EUC-JP and Shift_JIS files; if that's of greater interest. The GitHub is neither particularly recent or active. GoLang itself has a fast and robust regex, but the platinum searcher would be better recommended if it had a better user interest.

For a combination of speed and power indexed query languages such as ElasticSearch or Solr can be a long term investment that pays off, but not if you want a quick and simple replacement for grep. OTOH both have an API which can be called from any program you write, adding powerful searches to your program.

While it's possible to spawn an external program, execute a search, intercept its output and process it, calling an API is the way to go for power and performance.

This question was protected Aug 6 '15 at 19:34 with this caution:
  We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations.

While some answers suggest alternative ways to accomplish a search they don't explain why other than it's "free", "faster", "more sophisticated", "tons of features", etc. Don't try to sell it, just tell us "why your answer is right". I've attempted to teach how to choose what's best for the user, and why. This is why I offer yet another answer, when there are already so many. Otherwise I'd agree that there are already quite a few answers; I hope I've brought a lot new to the table.

When looking for the max performance you run into a lot of issue and potential bottlenecks. Running a simple hello world test is not necessarily going to find them all.

Possible limitations include:

• Kernel socket limitations: look in /proc/sys/net for lots of kernel tuning..
• process limits: check out ulimit as others have stated here
• as your application grows in complexity, it may not have enough CPU power to keep up with the number of connections coming in. Use top to see if your CPU is maxed
• number of threads? I'm not experienced with threading, but this may come into play in conjunction with the previous items.

The RegExp constructor creates a regular expression object for matching text with a pattern.

    var pattern1 = ':\\(|:=\\(|:-\\(';
    var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';
    var regex = new RegExp(pattern1 + '|' + pattern2, 'gi');
    str.match(regex);

Above code works perfectly for me...

You can use either of below :-

1) display : inline-block :

http://jsbin.com/feneni/edit?html,css,js,output

Uncomment the line

 float:left;
 clear:both 

and you will find that parent container has collapsed.

2) Using display : table

Also, one way to solve this is to use document.createElement and create your html img and set its attributes like this.

var image = document.createElement("img");
var imageParent = document.getElementById("Id of HTML element to append the img");
image.id = "Id";
image.className = "class";
image.src = searchPic.src;
imageParent.appendChild(image);

REMARK: One point is that Javascript community right now encourages developers to use document selectors such as querySelector, getElementById and getElementsByClassName rather than document["pic1"].

This solution works with versions of date which do not support date -d @. It does not require AWK or other commands. A Unix timestamp is the number of seconds since Jan 1, 1970, UTC so it is important to specify UTC.

date -d '1970-01-01 1357004952 sec UTC'
Mon Dec 31 17:49:12 PST 2012

If you are on a Mac, then use:

date -r 1357004952

Command for getting epoch:

date +%s
1357004952

To obtain the channel id you can do the following request which gives you the channel id and playlist id.

https://www.googleapis.com/youtube/v3/channels?part=contentDetails%2C+statistics%2Csnippet&mine=true&key={YOUR_API_KEY}

mine parameter means the current authorized user

as u said channel id is perfixed with UC+{your account id} which you get while login, you can use this one also without requesting the above url you can directly call the channel api with your google id and just prefix with UC

https://www.googleapis.com/youtube/v3/channels?part=contentDetails%2C+statistics%2Csnippet&id=UC{your account id}&key={YOUR_API_KEY}

This is not exactly showing you which rows are locked, but this may helpful to you.

You can check which statements are blocked by running this:

select cmd,* from sys.sysprocesses
where blocked > 0

It will also tell you what each block is waiting on. So you can trace that all the way up to see which statement caused the first block that caused the other blocks.

Edit to add comment from @MikeBlandford:

The blocked column indicates the spid of the blocking process. You can run kill {spid} to fix it.

In .NET, the difference between Dictionary<,> and HashTable is primarily that the former is a generic type, so you get all the benefits of generics in terms of static type checking (and reduced boxing, but this isn't as big as people tend to think in terms of performance - there is a definite memory cost to boxing, though).

Just right click on a table and select "backup". The popup will show various options, including "Format", select "plain" and you get plain SQL.

pgAdmin is just using pg_dump to create the dump, also when you want plain SQL.

It uses something like this:

pg_dump --user user --password --format=plain --table=tablename --inserts --attribute-inserts etc.

Typing the SET PATH command into the command shell every time you fire it up could get old for you pretty fast. Three alternatives:

1. Run javac from a batch (.CMD) file. Then you can just put the SET PATH into that file before your javac execution. Or you could do without the SET PATH if you simply code the explicit path to javac.exe
2. Set your enhanced, improved PATH in the "environment variables" configuration of your system.
3. In the long run you'll want to automate your Java compiling with Ant. But that will require yet another extension to PATH first, which brings us back to (1) and (2).

A StaticResource will be resolved and assigned to the property during the loading of the XAML which occurs before the application is actually run. It will only be assigned once and any changes to resource dictionary ignored.

A DynamicResource assigns an Expression object to the property during loading but does not actually lookup the resource until runtime when the Expression object is asked for the value. This defers looking up the resource until it is needed at runtime. A good example would be a forward reference to a resource defined later on in the XAML. Another example is a resource that will not even exist until runtime. It will update the target if the source resource dictionary is changed.

You may use this :

Download "angular-post-fix": "^0.1.0"

Then add 'httpPostFix' to your dependencies while declaring the angular module.

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

In XML

android:textStyle="bold" //only bold
android:textStyle="italic" //only italic
android:textStyle="bold|italic" //bold & italic

You can only use specific fonts sans, serif & monospace via xml, Java code can use custom fonts

android:typeface="monospace" // or sans or serif

Programmatically (Java code)

TextView textView = (TextView) findViewById(R.id.TextView1);

textView.setTypeface(Typeface.SANS_SERIF); //only font style
textView.setTypeface(null,Typeface.BOLD); //only text style(only bold)
textView.setTypeface(null,Typeface.BOLD_ITALIC); //only text style(bold & italic)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD); 
                                         //font style & text style(only bold)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD_ITALIC);
                                         //font style & text style(bold & italic)

List the packages by:

adb shell su 0 pm list packages

Review which package you want to uninstall and copy the package name from there. For example:

com.android.calculator2

Lastly type in:

adb uninstall com.android.calculator2 

and you are done.

It doesn't inherit from Element because not all event targets are elements.

From MDN:

Element, document, and window are the most common event targets, but other objects can be event targets too, for example XMLHttpRequest, AudioNode, AudioContext, and others.

Even the KeyboardEvent you're trying to use can occur on a DOM element or on the window object (and theoretically on other things), so right there it wouldn't make sense for evt.target to be defined as an Element.

If it is an event on a DOM element, then I would say that you can safely assume evt.target. is an Element. I don't think this is an matter of cross-browser behavior. Merely that EventTarget is a more abstract interface than Element.

The way to "start" the array that you want is:

arr = np.empty((0,3), int)

Which is an empty array but it has the proper dimensionality.

>>> arr
array([], shape=(0, 3), dtype=int64)

Then be sure to append along axis 0:

arr = np.append(arr, np.array([[1,2,3]]), axis=0)
arr = np.append(arr, np.array([[4,5,6]]), axis=0)

But, @jonrsharpe is right. In fact, if you're going to be appending in a loop, it would be much faster to append to a list as in your first example, then convert to a numpy array at the end, since you're really not using numpy as intended during the loop:

In [210]: %%timeit
   .....: l = []
   .....: for i in xrange(1000):
   .....:     l.append([3*i+1,3*i+2,3*i+3])
   .....: l = np.asarray(l)
   .....: 
1000 loops, best of 3: 1.18 ms per loop

In [211]: %%timeit
   .....: a = np.empty((0,3), int)
   .....: for i in xrange(1000):
   .....:     a = np.append(a, 3*i+np.array([[1,2,3]]), 0)
   .....: 
100 loops, best of 3: 18.5 ms per loop

In [214]: np.allclose(a, l)
Out[214]: True

The numpythonic way to do it depends on your application, but it would be more like:

In [220]: timeit n = np.arange(1,3001).reshape(1000,3)
100000 loops, best of 3: 5.93 µs per loop

In [221]: np.allclose(a, n)
Out[221]: True

In case the WebSocket server initiative disconnects the ws link after a few minutes there no messages sent between the server and client.

1. client sends a custom ping message, to keep alive by using the keepAlive function

2. server ignore the ping message and response a custom pong message

var timerID = 0; 
function keepAlive() { 
    var timeout = 20000;  
    if (webSocket.readyState == webSocket.OPEN) {  
        webSocket.send('');  
    }  
    timerId = setTimeout(keepAlive, timeout);  
}  
function cancelKeepAlive() {  
    if (timerId) {  
        clearTimeout(timerId);  
    }  
}

In my case it was something else, += operator caused this. I had to replace += X with field = field + X to overcome this. I assume this is a bug though I wasn't able to find any related KB on Microsoft sites.

I am using SQL Server 2008 R2(10.50.1600).

Note that neither DBCC DROPCLEANBUFFERS; nor DBCC FREEPROCCACHE; is supported in SQL Azure / SQL Data Warehouse.

However, if you need to reset the plan cache in SQL Azure, you can alter one of the tables in the query (for instance, just add then remove a column), this will have the side-effect of removing the plan from the cache.

I personally do this as a way of testing query performance without having to deal with cached plans.

No, there is no built-in MySQL command for that. There are various tools and scripts that support it, you can kill some connections manually or restart the server (but that will be slower).

Use SHOW PROCESSLIST to view all connections, and KILL the process ID's you want to kill.

You could edit the timeout setting to have the MySQL daemon kill the inactive processes itself, or raise the connection count. You can even limit the amount of connections per username, so that if the process keeps misbehaving, the only affected process is the process itself and no other clients on your database get locked out.

If you can't connect yourself anymore to the server, you should know that MySQL always reserves 1 extra connection for a user with the SUPER privilege. Unless your offending process is for some reason using a username with that privilege...

Then after you can access your database again, you should fix the process (website) that's spawning that many connections.

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

This message means that for some reason the garbage collector is taking an excessive amount of time (by default 98% of all CPU time of the process) and recovers very little memory in each run (by default 2% of the heap).

This effectively means that your program stops doing any progress and is busy running only the garbage collection at all time.

To prevent your application from soaking up CPU time without getting anything done, the JVM throws this Error so that you have a chance of diagnosing the problem.

The rare cases where I've seen this happen is where some code was creating tons of temporary objects and tons of weakly-referenced objects in an already very memory-constrained environment.

Check out the Java GC tuning guide, which is available for various Java versions and contains sections about this specific problem:

• Java 11 tuning guide has dedicated sections on excessive GC for different garbage collectors:
  • for the Parallel Collector
  • for the Concurrent Mark Sweep (CMS) Collector
  • there is no mention of this specific error condition for the Garbage First (G1) collector.
• Java 8 tuning guide and its Excessive GC section
• Java 6 tuning guide and its Excessive GC section.

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

Use the command as

java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>

The above command will set the mentioned paths to classpath only once for executing the class named TestClass.

If you want to execute more then one classes, then you can follow this

set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"

After this you can execute as many classes as you want just by simply typing

java <your-class-name>

The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)

If you want to set the classpth only once so that it could work for everytime, then do as follows

1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
    a.  Variable Name-     classpath
    b.  Variable Value-    .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.

Remember this will work every time. You don't need to explicitly set the classpath again and again.

NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.

Hope this will help you.

Not exactly a setting but you can override the default TrustManager and HostnameVerifier to accept anything. Not a safe approach but in your situation, it can be acceptable.

Here a more complete snippet that crops out the center of an [bitmap] of arbitrary dimensions and scales the result to your desired [IMAGE_SIZE]. So you will always get a [croppedBitmap] scaled square of the image center with a fixed size. ideal for thumbnailing and such.

Its a more complete combination of the other solutions.

final int IMAGE_SIZE = 255;
boolean landscape = bitmap.getWidth() > bitmap.getHeight();

float scale_factor;
if (landscape) scale_factor = (float)IMAGE_SIZE / bitmap.getHeight();
else scale_factor = (float)IMAGE_SIZE / bitmap.getWidth();
Matrix matrix = new Matrix();
matrix.postScale(scale_factor, scale_factor);

Bitmap croppedBitmap;
if (landscape){
    int start = (tempBitmap.getWidth() - tempBitmap.getHeight()) / 2;
    croppedBitmap = Bitmap.createBitmap(tempBitmap, start, 0, tempBitmap.getHeight(), tempBitmap.getHeight(), matrix, true);
} else {
    int start = (tempBitmap.getHeight() - tempBitmap.getWidth()) / 2;
    croppedBitmap = Bitmap.createBitmap(tempBitmap, 0, start, tempBitmap.getWidth(), tempBitmap.getWidth(), matrix, true);
}

Based upon dwanderson's helpful comment, I was able to do this in a Bash one-liner:

conda create --name envpython2 --file <(conda list -n env1 -e )

My badly named env was "env1" and the new one I wish to clone from it is "envpython2".

In Windows inorder to set

Step 1 : Right Click on MyComputer and click on properties .

Step 2 : Click on Advanced tab

Step 3: Click on Environment Variables

Step 4: Create a new class path for JAVA_HOME

Step 5: Enter the Variable name as JAVA_HOME and the value to your jdk bin path ie c:\Programfiles\Java\jdk-1.6\bin and

NOTE Make sure u start with .; in the Value so that it doesn't corrupt the other environment variables which is already set.

Step 6 : Follow the Above step and edit the Path in System Variables add the following ;c:\Programfiles\Java\jdk-1.6\bin in the value column.

Step 7 :Your are done setting up your environment variables for your Java , In order to test it go to command prompt and type

 java   

who will get a list of help doc

In order make sure whether compiler is setup Type in cmd

  javac

who will get a list related to javac

Hope this Helps !

For object iteration we usually use a for..in loop. This structure will loop through all enumerable properties, including ones who are inherited via prototypal inheritance. For example:

let obj = {_x000D_
  prop1: '1',_x000D_
  prop2: '2'_x000D_
}_x000D_
_x000D_
for(let el in obj) {_x000D_
  console.log(el);_x000D_
  console.log(obj[el]);_x000D_
}

However, for..in will loop over all enumerable elements and this will not able us to split the iteration in chunks. To achieve this we can use the built in Object.keys() function to retrieve all the keys of an object in an array. We then can split up the iteration into multiple for loops and access the properties using the keys array. For example:

let obj = {_x000D_
  prop1: '1',_x000D_
  prop2: '2',_x000D_
  prop3: '3',_x000D_
  prop4: '4',_x000D_
};_x000D_
_x000D_
const keys = Object.keys(obj);_x000D_
console.log(keys);_x000D_
_x000D_
_x000D_
for (let i = 0; i < 2; i++) {_x000D_
  console.log(obj[keys[i]]);_x000D_
}_x000D_
_x000D_
_x000D_
for (let i = 2; i < 4; i++) {_x000D_
  console.log(obj[keys[i]]);_x000D_
}

This simple trick works: Copy and Paste. Do NOT cut and paste. After you paste, then reselect the part you copied and go to EDIT, slide down to CLEAR, and CLEAR CONTENTS.

You'd be surprised to find out that 80/20 is quite a commonly occurring ratio, often referred to as the Pareto principle. It's usually a safe bet if you use that ratio.

However, depending on the training/validation methodology you employ, the ratio may change. For example: if you use 10-fold cross validation, then you would end up with a validation set of 10% at each fold.

There has been some research into what is the proper ratio between the training set and the validation set:

The fraction of patterns reserved for the validation set should be inversely proportional to the square root of the number of free adjustable parameters.

In their conclusion they specify a formula:

Validation set (v) to training set (t) size ratio, v/t, scales like ln(N/h-max), where N is the number of families of recognizers and h-max is the largest complexity of those families.

What they mean by complexity is:

Each family of recognizer is characterized by its complexity, which may or may not be related to the VC-dimension, the description length, the number of adjustable parameters, or other measures of complexity.

Taking the first rule of thumb (i.e.validation set should be inversely proportional to the square root of the number of free adjustable parameters), you can conclude that if you have 32 adjustable parameters, the square root of 32 is ~5.65, the fraction should be 1/5.65 or 0.177 (v/t). Roughly 17.7% should be reserved for validation and 82.3% for training.

If by "empty" you mean undefined, it is the way ng-expressions are interpreted. Then, you could use :

random.seed(a, version) in python is used to initialize the pseudo-random number generator (PRNG).

PRNG is algorithm that generates sequence of numbers approximating the properties of random numbers. These random numbers can be reproduced using the seed value. So, if you provide seed value, PRNG starts from an arbitrary starting state using a seed.

Argument a is the seed value. If the a value is None, then by default, current system time is used.

and version is An integer specifying how to convert the a parameter into a integer. Default value is 2.

import random
random.seed(9001)
random.randint(1, 10) #this gives output of 1
# 1

If you want the same random number to be reproduced then provide the same seed again

random.seed(9001)
random.randint(1, 10) # this will give the same output of 1
# 1

If you don't provide the seed, then it generate different number and not 1 as before

random.randint(1, 10) # this gives 7 without providing seed
# 7

If you provide different seed than before, then it will give you a different random number

random.seed(9002)
random.randint(1, 10) # this gives you 5 not 1
# 5

So, in summary, if you want the same random number to be reproduced, provide the seed. Specifically, the same seed.

In addition to the answers above you can pass in command line parameters to the mysqld process for logging options instead of manually editing your conf file. For example, to enable general logging and specifiy a file:

mysqld --general-log --general-log-file=/var/log/mysql.general.log

Confirming other answers above, mysqld --help --verbose gives you the values from the conf file (so running with command line options general-log is FALSE); whereas mysql -se "SHOW VARIABLES" | grep -e log_error -e general_log gives:

general_log     ON
general_log_file        /var/log/mysql.general.log

Use slightly more compact syntax for the error log:

mysqld --general-log --general-log-file=/var/log/mysql.general.log --log-error=/var/log/mysql.error.log

After hours of having the same problem, notice that if your jar is on the libs folder will cause problem once you set it upon the "Dependencies ", so i just comment the file tree dependencies and keep the one using

dependencies

//compile fileTree(dir: 'libs', include: ['*.jar'])  <-------- commented one 
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.android.support:appcompat-v7:22.2.1'

and the problem was solved.

No you don't need to check if you're in the main thread. Here is how you can do this in Swift:

runThisInMainThread { () -> Void in
    runThisInMainThread { () -> Void in
        // No problem
    }
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

The accepted answer will work if you can easily reproduce the issue. However, as a matter of best practice, you should be catching any exceptions (and logging) that are executed within a task. Otherwise, your application will crash if anything unexpected occurs within the task.

Task.Factory.StartNew(x=>
   throw new Exception("I didn't account for this");
)

However, if we do this, at least the application does not crash.

Task.Factory.StartNew(x=>
   try {
      throw new Exception("I didn't account for this");
   }
   catch(Exception ex) {
      //Log ex
   }
)

With parallel execution, global variables can cause unexpected results if you don't understand what is happening. Here is an example of using a global variable within multiprocessing. We can clearly see that each process works with its own copy of the variable:

import multiprocessing
import os
import random
import sys
import time

def worker(new_value):
    old_value = get_value()
    set_value(random.randint(1, 99))
    print('pid=[{pid}] '
          'old_value=[{old_value:2}] '
          'new_value=[{new_value:2}] '
          'get_value=[{get_value:2}]'.format(
          pid=str(os.getpid()),
          old_value=old_value,
          new_value=new_value,
          get_value=get_value()))

def get_value():
    global global_variable
    return global_variable

def set_value(new_value):
    global global_variable
    global_variable = new_value

global_variable = -1

print('before set_value(), get_value() = [%s]' % get_value())
set_value(new_value=-2)
print('after  set_value(), get_value() = [%s]' % get_value())

processPool = multiprocessing.Pool(processes=5)
processPool.map(func=worker, iterable=range(15))

Output:

before set_value(), get_value() = [-1]
after  set_value(), get_value() = [-2]
pid=[53970] old_value=[-2] new_value=[ 0] get_value=[23]
pid=[53971] old_value=[-2] new_value=[ 1] get_value=[42]
pid=[53970] old_value=[23] new_value=[ 4] get_value=[50]
pid=[53970] old_value=[50] new_value=[ 6] get_value=[14]
pid=[53971] old_value=[42] new_value=[ 5] get_value=[31]
pid=[53972] old_value=[-2] new_value=[ 2] get_value=[44]
pid=[53973] old_value=[-2] new_value=[ 3] get_value=[94]
pid=[53970] old_value=[14] new_value=[ 7] get_value=[21]
pid=[53971] old_value=[31] new_value=[ 8] get_value=[34]
pid=[53972] old_value=[44] new_value=[ 9] get_value=[59]
pid=[53973] old_value=[94] new_value=[10] get_value=[87]
pid=[53970] old_value=[21] new_value=[11] get_value=[21]
pid=[53971] old_value=[34] new_value=[12] get_value=[82]
pid=[53972] old_value=[59] new_value=[13] get_value=[ 4]
pid=[53973] old_value=[87] new_value=[14] get_value=[70]

It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:

Access-Control-Allow-Origin:*

or

Access-Control-Allow-Origin:your domain

In Apache config files, the code is like this:

Header set Access-Control-Allow-Origin "*"

In nodejs,the code is like this:

res.setHeader('Access-Control-Allow-Origin','*');

it works for me, try This.. you need to configure your terminal with remote access.

     git config --global user.name "abc"
     git config --global user.email "[email protected]"

I needed the last day of the next month, maybe someone will need it:

echo date("Y-m-t", strtotime("next month")); //is 2020-08-13, return 2020-09-30

Complementing Aillyn's answer, you could use a function like the one below to mimic the behavior of file_get_contents:

function get_content($URL){
      $ch = curl_init();
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_URL, $URL);
      $data = curl_exec($ch);
      curl_close($ch);
      return $data;
}

echo get_content('http://example.com');

Here is a good introduction to logging in Java: http://www.javapractices.com/topic/TopicAction.do?Id=143

Java comes with a logging API since it's 1.4.2 version: http://download.oracle.com/javase/1.4.2/docs/guide/util/logging/overview.html

You can also use other logging frameworks like Apache Log4j which is the most popular one: http://logging.apache.org/log4j

I suggest you to use a logging abstraction framework which allows you to change your logging framework without re-factoring you code. So you can starts by using Jul (Java Util Logging) then swith to Log4j without changing you code. The most popular logging facade is slf4j: http://www.slf4j.org/

Regards,

If it matters whether the file you're looking for is a directory and not just a file, you could use File.directory? or Dir.exist?. This will return true only if the file exists and is a directory.

As an aside, a more idiomatic way to write the method would be to take advantage of the fact that Ruby automatically returns the result of the last expression inside the method. Thus, you could write it like this:

def directory_exists?(directory)
  File.directory?(directory)
end

Note that using a method is not necessary in the present case.

I used $(document).on("keydown").

On some browsers keyCode is not supported. The same with which so if keyCode is not supported you need to use which and vice versa.

$(document).on("keydown", function(e) {_x000D_
  const ENTER_KEY_CODE = 13;_x000D_
  const ENTER_KEY = "Enter";_x000D_
  var code = e.keyCode || e.which_x000D_
  var key = e.key_x000D_
  if (code == ENTER_KEY_CODE || key == ENTER_KEY) {_x000D_
    console.log("Enter key pressed")_x000D_
  }_x000D_
});

Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.

DECLARE @CountResults TABLE (CountReturned INT)
DECLARE 
    @SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
    , @Count INT

INSERT @CountResults
EXEC(@SqlStatement)

SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count

function json2array(json){
    var result = [];
    var keys = Object.keys(json);
    keys.forEach(function(key){
        result.push(json[key]);
    });
    return result;
}

My understanding is that a mutex is only for use within a single process, but across its many threads, whereas a semaphore may be used across multiple processes, and across their corresponding sets of threads.

Also, a mutex is binary (it's either locked or unlocked), whereas a semaphore has a notion of counting, or a queue of more than one lock and unlock requests.

Could someone verify my explanation? I'm speaking in the context of Linux, specifically Red Hat Enterprise Linux (RHEL) version 6, which uses kernel 2.6.32.

I think leverage this functionality using Java

long time= System.currentTimeMillis();

this will return current time in milliseconds mode . this will surely work

long time= System.currentTimeMillis();
android.util.Log.i("Time Class ", " Time value in millisecinds "+time);

Here is my logcat using the above function

05-13 14:38:03.149: INFO/Time Class(301): Time value in millisecinds 1368436083157

If you got any doubt with millisecond value .Check Here

EDIT : Time Zone I used to demo the code IST(+05:30) ,So if you check milliseconds that mentioned in log to match with time in log you might get a different value based your system timezone

EDIT: This is easy approach .but if you need time zone or any other details I think this won't be enough Also See this approach using android api support

Why not try this?:

import os

def touch(fname):
    try:
        os.utime(fname, None)
    except OSError:
        open(fname, 'a').close()

I believe this eliminates any race condition that matters. If the file does not exist then an exception will be thrown.

The only possible race condition here is if the file is created before open() is called but after os.utime(). But this does not matter because in this case the modification time will be as expected since it must have happened during the call to touch().

Follow the next steps:

1. Open the app.config and comment on the connection string (save file)
2. Open the edmx (go to properties, the connection string should be blank), close the edmx file again
3. Open the app.config and uncomment the connection string (save file)
4. Open the edmx, go to properties, you should see the connection string uptated!!

Quoting API on referencedColumnName:

The name of the column referenced by this foreign key column.

Default (only applies if single join column is being used): The same name as the primary key column of the referenced table.

Q/A

Where this would be used?

When there is a composite PK in referenced table, then you need to specify column name you are referencing.

String g = "line";
//string to char
char c = g.charAt(0);
char[] c_arr = g.toCharArray();
//char to string
char[] charArray = {'a', 'b', 'c'};
String str = String.valueOf(charArray);
//(or iterate the charArray and append each character to str -> str+=charArray[i])

//or String s= new String(chararray);

Replace:

myBinding.Source = ViewModel.SomeString;

with:

myBinding.Source = ViewModel;

Example:

Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);

Your source should be just ViewModel, the .SomeString part is evaluated from the Path (the Path can be set by the constructor or by the Path property).

Try to use this:

using (var handler = new HttpClientHandler() { CookieContainer = new CookieContainer() })
{
    using (var client = new HttpClient(handler) { BaseAddress = new Uri("site.com") })
    {
        //add parameters on request
        var body = new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>("test", "test"),
            new KeyValuePair<string, string>("test1", "test1")
        };

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "site.com");

        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded; charset=UTF-8"));
        client.DefaultRequestHeaders.Add("Upgrade-Insecure-Requests", "1");
        client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");
        client.DefaultRequestHeaders.Add("X-MicrosoftAjax", "Delta=true");
        //client.DefaultRequestHeaders.Add("Accept", "*/*");

        client.Timeout = TimeSpan.FromMilliseconds(10000);

        var res = await client.PostAsync("", new FormUrlEncodedContent(body));

        if (res.IsSuccessStatusCode)
        {
            var exec = await res.Content.ReadAsStringAsync();
            Console.WriteLine(exec);
        }                    
    }
}

Yes, this is possible.

<form id="formName" action="<?php echo $_SERVER['PHP_SELF'];?>" method="get">
    <input type ="checkbox" name="cBox[]" value = "3" onchange="document.getElementById('formName').submit()">3</input>
    <input type ="checkbox" name="cBox[]" value = "4" onchange="document.getElementById('formName').submit()">4</input>
    <input type ="checkbox" name="cBox[]" value = "5" onchange="document.getElementById('formName').submit()">5</input>
    <input type="submit" name="submit" value="Search" />
</form>

By adding onchange="document.getElementById('formName').submit()" to each checkbox, you'll submit any time a checkbox is changed.

If you're OK with jQuery, it's even easier (and unobtrusive):

$(document).ready(function(){
    $("#formname").on("change", "input:checkbox", function(){
        $("#formname").submit();
    });
});

For any number of checkboxes in your form, when the "change" event happens, the form is submitted. This will even work if you dynamically create more checkboxes thanks to the .on() method.

This is not a problem with the function at all.

It took me a bit of digging, but the problem is in copying and pasting. Try copying this: RANDBETWEEN(0,6553??5) string, posted in your original question, and paste it into a Hex Editor, then you'll see that there are actually two null characters in the 65535:

00000000  52 41 4E 44 42 45 54 57 45 45 4E 28 30 2C 36 35  RANDBETWEEN(0,65
00000010  35 33 00 00 35 29                                53?..?5)

Just to add my $.02 here, I ran into a similar issue just yesterday, where 168 of my tests were missing. I tried most everything in this post - most especially making sure my version(s) of NUnit were the same - all to no avail. I then remembered that I had my tests divided into playlists; and these do not update automatically as you add new tests. So, when I deleted the playlists, BAM!, all of my tests were back once more.

Further to Joao Cunha's answer, this problem is now on Mozilla's ToDo List and is targeted for ver 35.

Another aproach is:

But Object spread isn't yet standardized.

I have a convention of naming xibs with views in them the same as the view. Same as one would do for a view controller. Then, I don't have to write out class names in code. I load a UIView from a nib file with the same name.

Example for a class called MyView.

• Create a nib file called MyView.xib in Interface Builder
• In Interface Builder, add a UIView. Set its class to MyView. Customize to your heart's content, wire up instance variables of MyView to subviews you might want to access later.

• In your code, create a new MyView like this:

  MyView *myView = [MyView nib_viewFromNibWithOwner:owner];

Here's the category for this:

@implementation UIView (nib)

+ (id) nib_viewFromNib {
    return [self nib_viewFromNibWithOwner:nil];
}

+ (id) nib_viewFromNibWithOwner:(id)owner {
    NSString *className = NSStringFromClass([self class]);
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:className owner:owner options:nil];
    UIView *view = nil;
    for(UIView *v in nib) {
        if ([v isKindOfClass:[self class]]) {
            view = v;
            break;
        }
    }
    assert(view != nil && "View for class not found in nib file");
    [view nib_viewDidLoad];
    return view;
}

// override this to do custom setup
-(void)nib_viewDidLoad {

}

I'd then wire up buttons with actions from the controller I am using, and set things on labels using the outlets in my custom view subclass.

This might be a simple solution to achieve this:

INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
  FROM dual
 WHERE NOT EXISTS (SELECT 1 
                     FROM funds 
                    WHERE ID = 23
                      AND date = DATE('2013-02-12'));

p.s. alternatively (if ID a primary key):

 INSERT INTO funds (ID, date, price)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need

see this Fiddle.

One shouldn't use set_yticklabels to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter), which is usually undesired. The easiest is to set the respective tick_params:

ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)

or

ax.tick_params(labelsize=8)

in case both axes shall have the same size.

Of course using the rcParams as in @tmdavison's answer is possible as well.

public class TestStringCount {

  public static void main(String[] args) {
    int count=0;
    boolean word= false;
    String str = "how ma ny wo rds are th ere in th is sente nce";
    char[] ch = str.toCharArray();
    for(int i =0;i<ch.length;i++){
        if(!(ch[i]==' ')){
            for(int j=i;j<ch.length;j++,i++){
                if(!(ch[j]==' ')){
                    word= true;
                    if(j==ch.length-1){
                        count++;
                    }
                    continue;
                }
                else{
                    if(word){
                        count++;
                    }
                    word = false;
                }
            }
        }
        else{
            continue;
        }
    }
    System.out.println("there are "+(count)+" words");      
    }
}

Do this for a cool border and font effect:

#ck-button:hover {             /*ADD :hover */
    margin:4px;
    background-color:#EFEFEF;
    border-radius:4px;
    border:1px solid red;      /*change border color*/ 
    overflow:auto;
    float:left;
    color:red;                 /*add font color*/
}

This is because chrome handles the mailto in different way. You can go to chrome://settings/handlers and make sure that which is the default handler. In your case it will be none (i.e. not listed). Now go to gmail.com. You should see something like this when you click on the button beside the bookmark button.

If you wish to open all email links through gmail then set "Use Gmail". Now when you click on mailto button, chrome will automatically opens in gmail.

I'll not address the order of tests, sorry. Others already did it. Also, if you know about "ordered tests" - well, this is MS VS's response to the problem. I know that those ordered-tests are no fun. But they thought it will be "it" and there's really nothing more in MSTest about that.

I write about one of your assumptions:

as there is no way to tear down the static class.

Unless your static class represents some process-wide external state external to your code (like ie. the state of an unmanaged native DLL library thats P/Invoked by the rest of your code), your assumption that there is no way is not true.

If your static class refers to this, then sorry, you are perfectly right, the rest of this anwer is irrelevant. Still, as you didn't say that, I assume your code is "managed".

Think and check the AppDomain thingy. Rarely it is needed, but this is exactly the case when you'd probably like to use them.

You can create a new AppDomain, and instantiate the test there, and run the test method there. Static data used by managed code will isolated there and upon completion, you will be able to unload the AppDomain and all the data, statics included, will evaporate. Then, next test would initialize another appdomain, and so on.

This will work unless you have external state that you must track. AppDomains only isolate the managed memory. Any native DLL will still be load per-process and their state will be shared by all AppDomains.

Also, creating/tearing down the appdomains will, well, slow down the tests. Also, you may have problems with assembly resolution in the child appdomain, but they are solvable with reasonable amount of reusable code.

Also, you may have small problems with passing test data to - and back from - the child AppDomain. Objects passed will either have to be serializable in some way, or be MarshalByRef or etc. Talking cross-domain is almost like IPC.

However, take care here, it will be 100% managed talking. If you take some extra care and add a little work to the AppDomain setup, you will be able to even pass delegates and run them in the target domain. Then, instead of making some hairy cross-domain setup, you can wrap your tests with to something like:

void testmethod()
{
    TestAppDomainHelper.Run( () =>
    {
        // your test code
    });
}

or even

[IsolatedAppDomain]
void testmethod()
{
    // your test code
}

if your test framework supports creating such wrappers/extensions. After some initial research and work, using them is almost trivial.

Declare it as a decimal which uses the int variable and divide this by 100

int number = 700
decimal correctNumber = (decimal)number / 100;

Edit: Bala was faster with his reaction

An efficient code in C++ that works for any angle and in both: radians and degrees is:

inline double getAbsoluteDiff2Angles(const double x, const double y, const double c)
{
    // c can be PI (for radians) or 180.0 (for degrees);
    return c - fabs(fmod(fabs(x - y), 2*c) - c);
}

This worked for me to solve jpeg and zlib error :

There are many open source projects that can generate screenshots. For example PhantomJS, webkit2png etc

The big problem with these projects is that they are based on older browser technology and have problems rendering many sites, especially sites that use webfonts, flexbox, svg and various other additions to the HTML5 and CSS spec over the last couple of months/years.

I've tried a few of the third party services, and most are based on PhantomJS, meaning they also produce poor quality screenshots. The best third party service for generating website screenshots is urlbox.io. It is a paid service, although there is a free 7-day trial to test it out without committing to any paid plan.

Here is a link to the documentation, and below are simple steps to get it working in PHP with composer.

// 1 . Get the urlbox/screenshots composer package (on command line):
composer require urlbox/screenshots

// 2. Set up the composer package with Urlbox API credentials:
$urlbox = UrlboxRenderer::fromCredentials('API_KEY', 'API_SECRET');

// 3. Set your options (all options such as full page/full height screenshots, retina resolution, viewport dimensions, thumbnail width etc can be set here. See the docs for more.)
$options['url'] = 'example.com';

// 4. Generate the Urlbox url
$urlboxUrl = $urlbox->generateUrl($options);
// $urlboxUrl is now 'https://api.urlbox.io/v1/API_KEY/TOKEN/png?url=example.com'

// 5. Now stick it in an img tag, when the image is loaded in browser, the API call to urlbox will be triggered and a nice PNG screenshot will be generated!
<img src="$urlboxUrl" />

For e.g. here's a full height screenshot of this very page:

https://api.urlbox.io/v1/ca482d7e-9417-4569-90fe-80f7c5e1c781/8f1666d1f4195b1cb84ffa5f992ee18992a2b35e/png?url=http%3A%2F%2Fstackoverflow.com%2Fquestions%2F757675%2Fwebsite-screenshots-using-php%2F43652083%2343652083&full_page=true

You can declare a dictionary inside a dictionary by nesting the {} containers:

d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}

And then you can access the elements using the [] syntax:

print d['dict1']           # {'foo': 1, 'bar': 2}
print d['dict1']['foo']    # 1
print d['dict2']['quux']   # 4

Given the above, if you want to add another dictionary to the dictionary, it can be done like so:

d['dict3'] = {'spam': 5, 'ham': 6}

or if you prefer to add items to the internal dictionary one by one:

d['dict4'] = {}
d['dict4']['king'] = 7
d['dict4']['queen'] = 8

Use the following will help

Just for a more animated and cute solution:

$(window).scroll(function(){
  $("#div").stop().animate({"marginTop": ($(window).scrollTop()) + "px", "marginLeft":($(window).scrollLeft()) + "px"}, "slow" );
});

And a pen for those who want to see: http://codepen.io/think123/full/mAxlb, and fork: http://codepen.io/think123/pen/mAxlb

Update: and a non-animated jQuery solution:

$(window).scroll(function(){
  $("#div").css({"margin-top": ($(window).scrollTop()) + "px", "margin-left":($(window).scrollLeft()) + "px"});
});

Permanent:

Apart from the difference that Scripting language is Interpreted and Programming language is Compiled, there is another difference as below, which I guess has been missed..

A scripting language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. In such systems, useful functionality is already available through a user interface, and the scripting language is a mechanism for exposing that functionality to program control.

Whereas a Programming Language generally is used to code the system from Scratch.

Using UIApplication.openSettingsURLString

Update for Swift 5.1

 override func viewDidAppear(_ animated: Bool) {
    let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (_) -> Void in

        guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        }
    }
    alertController.addAction(settingsAction)
    let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)
}

Swift 4.2

override func viewDidAppear(_ animated: Bool) {
    let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)

In my case, I had left over references to classes in a recently removed composer package. In your laravel app, check config/app.php, particularly the providers and aliases properties, for references to the class specified in the error.

It is written here that "By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing."

As it seems that these new checkboxes appeared with Android 2.3, I understand that my previous versions of Android Studio (at least the 2.2) did sign with both signatures. So, to continue as I did before, I think that it is better to check both checkboxes.

EDIT March 31st, 2017 : submitted several apps with both signatures => no problem :)

You've got an array of objects, so you'll need to use ng-repeat twice, like:

<ul ng-repeat="item in items">
  <li ng-repeat="(key, val) in item">
    {{key}}: {{val}}
  </li>
</ul>

Example: http://jsfiddle.net/Vwsej/

Edit:

Note that properties order in objects are not guaranteed.

<table>
    <tr>
        <th ng-repeat="(key, val) in items[0]">{{key}}</th>
    </tr>
    <tr ng-repeat="item in items">
        <td ng-repeat="(key, val) in item">{{val}}</td>
    </tr>
</table>

Example: http://jsfiddle.net/Vwsej/2/

Example JS Fiddle

Bullets take the color property of the list:

.listStyle {
    color: red;
}

Note if you want your list text to be a different colour, you have to wrap it in say, a p, for example:

.listStyle p {
    color: black;
}

Example HTML:

<ul class="listStyle">
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
</ul>

git diff -a treats all file as text and it works for me.

Since (still) nobody got check-mark, I assume that you have some practical issue in mind, mostly because you haven't specified what type of vector you want to convert to numeric. I suggest that you should apply transform function in order to complete your task.

Now I'm about to demonstrate certain "conversion anomaly":

# create dummy data.frame
d <- data.frame(char = letters[1:5], 
                fake_char = as.character(1:5), 
                fac = factor(1:5), 
                char_fac = factor(letters[1:5]), 
                num = 1:5, stringsAsFactors = FALSE)

Let us have a glance at data.frame

> d
  char fake_char fac char_fac num
1    a         1   1        a   1
2    b         2   2        b   2
3    c         3   3        c   3
4    d         4   4        d   4
5    e         5   5        e   5

and let us run:

> sapply(d, mode)
       char   fake_char         fac    char_fac         num 
"character" "character"   "numeric"   "numeric"   "numeric" 
> sapply(d, class)
       char   fake_char         fac    char_fac         num 
"character" "character"    "factor"    "factor"   "integer" 

Now you probably ask yourself "Where's an anomaly?" Well, I've bumped into quite peculiar things in R, and this is not the most confounding thing, but it can confuse you, especially if you read this before rolling into bed.

Here goes: first two columns are character. I've deliberately called 2^nd one fake_char. Spot the similarity of this character variable with one that Dirk created in his reply. It's actually a numerical vector converted to character. 3^rd and 4^th column are factor, and the last one is "purely" numeric.

If you utilize transform function, you can convert the fake_char into numeric, but not the char variable itself.

> transform(d, char = as.numeric(char))
  char fake_char fac char_fac num
1   NA         1   1        a   1
2   NA         2   2        b   2
3   NA         3   3        c   3
4   NA         4   4        d   4
5   NA         5   5        e   5
Warning message:
In eval(expr, envir, enclos) : NAs introduced by coercion

but if you do same thing on fake_char and char_fac, you'll be lucky, and get away with no NA's:

> transform(d, fake_char = as.numeric(fake_char), 
               char_fac = as.numeric(char_fac))

  char fake_char fac char_fac num
1    a         1   1        1   1
2    b         2   2        2   2
3    c         3   3        3   3
4    d         4   4        4   4
5    e         5   5        5   5

If you save transformed data.frame and check for mode and class, you'll get:

> D <- transform(d, fake_char = as.numeric(fake_char), 
                    char_fac = as.numeric(char_fac))

> sapply(D, mode)
       char   fake_char         fac    char_fac         num 
"character"   "numeric"   "numeric"   "numeric"   "numeric" 
> sapply(D, class)
       char   fake_char         fac    char_fac         num 
"character"   "numeric"    "factor"   "numeric"   "integer"

So, the conclusion is: Yes, you can convert character vector into a numeric one, but only if it's elements are "convertible" to numeric. If there's just one character element in vector, you'll get error when trying to convert that vector to numerical one.

And just to prove my point:

> err <- c(1, "b", 3, 4, "e")
> mode(err)
[1] "character"
> class(err)
[1] "character"
> char <- as.numeric(err)
Warning message:
NAs introduced by coercion 
> char
[1]  1 NA  3  4 NA

And now, just for fun (or practice), try to guess the output of these commands:

> fac <- as.factor(err)
> fac
???
> num <- as.numeric(fac)
> num
???

Kind regards to Patrick Burns! =)

From Spark 2.0 onwards what you can do is use SparkSession to get this done as a one liner:

val spark = SparkSession.builder.config(conf).getOrCreate()

and then as @SandeepPurohit said:

val dataFrame = spark.read.format("CSV").option("header","true").load(csvfilePath)

I hope it solved your question !

P.S: SparkSession is the new entry point introduced in Spark 2.0 and can be found under spark_sql package

echo 5/2 | bc -l

this '-l' option in 'bc' allows floating results

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

I had to benchmark the different ways. I shall comment on my findings but, in short, the fastest way is to use a plain old BufferedInputStream over a FileInputStream. If many files must be read then three threads will reduce the total execution time to roughly half, but adding more threads will progressively degrade performance until making it take three times longer to complete with twenty threads than with just one thread.

The assumption is that you must read a file and do something meaningful with its contents. In the examples here is reading lines from a log and count the ones which contain values that exceed a certain threshold. So I am assuming that the one-liner Java 8 Files.lines(Paths.get("/path/to/file.txt")).map(line -> line.split(";")) is not an option.

I tested on Java 1.8, Windows 7 and both SSD and HDD drives.

I wrote six different implementations:

rawParse: Use BufferedInputStream over a FileInputStream and then cut lines reading byte by byte. This outperformed any other single-thread approach, but it may be very inconvenient for non-ASCII files.

lineReaderParse: Use a BufferedReader over a FileReader, read line by line, split lines by calling String.split(). This is approximatedly 20% slower that rawParse.

lineReaderParseParallel: This is the same as lineReaderParse, but it uses several threads. This is the fastest option overall in all cases.

nioFilesParse: Use java.nio.files.Files.lines()

nioAsyncParse: Use an AsynchronousFileChannel with a completion handler and a thread pool.

nioMemoryMappedParse: Use a memory-mapped file. This is really a bad idea yielding execution times at least three times longer than any other implementation.

These are the average times for reading 204 files of 4 MB each on an quad-core i7 and SSD drive. The files are generated on the fly to avoid disk caching.

rawParse                11.10 sec
lineReaderParse         13.86 sec
lineReaderParseParallel  6.00 sec
nioFilesParse           13.52 sec
nioAsyncParse           16.06 sec
nioMemoryMappedParse    37.68 sec

I found a difference smaller than I expected between running on an SSD or an HDD drive being the SSD approximately 15% faster. This may be because the files are generated on an unfragmented HDD and they are read sequentially, therefore the spinning drive can perform nearly as an SSD.

I was surprised by the low performance of the nioAsyncParse implementation. Either I have implemented something in the wrong way or the multi-thread implementation using NIO and a completion handler performs the same (or even worse) than a single-thread implementation with the java.io API. Moreover the asynchronous parse with a CompletionHandler is much longer in lines of code and tricky to implement correctly than a straight implementation on old streams.

Now the six implementations followed by a class containing them all plus a parametrizable main() method that allows to play with the number of files, file size and concurrency degree. Note that the size of the files varies plus minus 20%. This is to avoid any effect due to all the files being of exactly the same size.

FULL RUNNABLE IMPLEMENTATION OF ALL CASES

I had a similar issue using the JAXB reference implementation and JBoss AS 7.1. I was able to write an integration test that confirmed JAXB worked outside of the JBoss environment (suggesting the problem might be the class loader in JBoss).

This is the code that was giving the error (i.e. not working):

private static final JAXBContext JC;

static {
    try {
        JC = JAXBContext.newInstance("org.foo.bar");
    } catch (Exception exp) {
        throw new RuntimeException(exp);
    }
}

and this is the code that worked (ValueSet is one of the classes marshaled from my XML).

private static final JAXBContext JC;

static {
    try {
        ClassLoader classLoader = ValueSet.class.getClassLoader();
        JC = JAXBContext.newInstance("org.foo.bar", classLoader);
    } catch (Exception exp) {
        throw new RuntimeException(exp);
    }
}

In some cases I got the Class nor any of its super class is known to this context. In other cases I also got an exception of org.foo.bar.ValueSet cannot be cast to org.foo.bar.ValueSet (similar to the issue described here: ClassCastException when casting to the same class).

select into is used in pl/sql to set a variable to field values. Instead, use

create table new_table as select * from old_table

The best i could think of a variable is a int Is a combination with MySQL's functions CAST() and LENGTH().
This method will work on strings, integers, doubles/floats datatypes.

SELECT (LENGTH(CAST(<data> AS UNSIGNED))) = (LENGTH(<data>)) AS is_int

see demo http://sqlfiddle.com/#!9/ff40cd/44

it will fail if the column has a single character value. if column has a value 'A' then Cast('A' as UNSIGNED) will evaluate to 0 and LENGTH(0) will be 1. so LENGTH(Cast('A' as UNSIGNED))=LENGTH(0) will evaluate to 1=1 => 1

True Waqas Malik totally fogotten to test that case. the patch is.

SELECT <data>, (LENGTH(CAST(<data> AS UNSIGNED))) = CASE WHEN CAST(<data> AS UNSIGNED) = 0 THEN CAST(<data> AS UNSIGNED) ELSE (LENGTH(<data>)) END AS is_int;

Here's an alternative solution using requests:

import requests
wjdata = requests.get('url').json()
print wjdata['data']['current_condition'][0]['temp_C']

Starting with Spring 4.1, We can directly set the property in application.yml using the @TestPropertySource annotation.

@RunWith(SpringRunner.class)
@SpringBootTest
@TestPropertySource(properties = {"yoursection.yourparameter=your_value"})
public MyIntTest
{
 //your test methods
}

Just convert your yaml parameters into complete property structure. For example: If content of application.yml is like below

yoursection:
  yourparameter:your_value

Then value to go inside the @TestPropertySource will be,

yoursection.yourparameter=your_value

@jbochniak: Thanks, although at first read I thought I've already discovered all of this, it turned out that your example (esp. the version of the Mongo Docker image) helped me out!

That version (v3.4.2) and the v3.4 (currently corresponding to v3.4.3) still support 'MONGO_INITDB_ROOT' specified through those variables, as of v3.5 (at least tags '3' and 'latest') DON'T work as described in your answer and in the docs.

I quickly had a look at the code on GitHub, but saw similar usage of these variables and couldn't find the bug immediately, should do so before filing this as a bug...

It may also happen in the following case:

eg. if we consider the push function of a stack:

typedef struct stack
{
    int a[20];
    int head;
}stack;

void push(stack **s)
{
    int data;
    printf("Enter data:");
    scanf("%d",&(*s->a[++*s->head])); /* this is where the error is*/
}

main()
{
    stack *s;
    s=(stack *)calloc(1,sizeof(stack));
    s->head=-1;
    push(&s);
    return 0;
}

The error is in the push function and in the commented line. The pointer s has to be included within the parentheses. The correct code:

scanf("%d",&( (*s)->a[++(*s)->head]));

If you add the android:theme="@style/Theme.AppCompat.Light" to <application> in AndroidManifest.xml file, problem is solving.

It is probably due to an Outdated yarn.lock file

Just run the following commands

yarn install
git add yarn.lock

in your question you mentioned that your phpinfo was stating that apache was loading xdebug's configuration in /etc/php5/apache2/conf.d/xdebug.ini In many of the instructions online you may note that they ask you to put xdebug config in php.ini (and that is what I did) HOWEVER, if the configuration is set to /etc/php5/apache2/conf.d/xdebug.ini, then you should remove the [XDebug] configuration settings from /etc/php5/apache2/php.ini and put it in /etc/php5/apache2/conf.d/xdebug.ini INSTEAD. Once I removed from /etc/php5/apache2/php.ini and put in /etc/php5/apache2/conf.d/xdebug.ini instead, and restarted apache, it worked!!

Therefore, in your /etc/php5/apache2/conf.d/xdebug.ini, put the following:

[XDebug]
zend_extension="/usr/lib/php5/20121212+lfs/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_port="9000"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="/home/paul/tmp"

xdebug.remote_host="localhost"
xdebug.remote_handler="dbgp";
xdebug.idekey="phpstorm_xdebug"

then remove this from the /etc/php5/apache2/php.ini if you put it there as well.

Then do:

sudo service apache2 restart

Then it should work!!!

I usually use

#define INFINITY (1e999)

or

const double INFINITY = 1e999

which works at least in IEEE 754 contexts because the highest representable double value is roughly 1e308. 1e309 would work just as well, as would 1e99999, but three nines is sufficient and memorable. Since this is either a double literal (in the #define case) or an actual Inf value, it will remain infinite even if you're using 128-bit (“long double”) floats.

I would prefer std::distance(vec.begin(), it) as it will allow me to change the container without any code changes. For example, if you decide to use std::list instead of std::vector which doesn't provide a random access iterator your code will still compile. Since std::distance picks up the optimal method depending on iterator traits you'll not have any performance degradation either.

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

@Configuration
public class CorsConfig implements WebMvcConfigurer {

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

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

I had to modify the Security configuration also like below:

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

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

Time to go back in time for a lesson. While we don't think about these things much in our fancy managed languages today, they are built on the same foundation, so let's look at how memory is managed in C.

Before I dive in, a quick explanation of what the term "pointer" means. A pointer is simply a variable that "points" to a location in memory. It doesn't contain the actual value at this area of memory, it contains the memory address to it. Think of a block of memory as a mailbox. The pointer would be the address to that mailbox.

In C, an array is simply a pointer with an offset, the offset specifies how far in memory to look. This provides O(1) access time.

  MyArray   [5]
     ^       ^
  Pointer  Offset

All other data structures either build upon this, or do not use adjacent memory for storage, resulting in poor random access look up time (Though there are other benefits to not using sequential memory).

For example, let's say we have an array with 6 numbers (6,4,2,3,1,5) in it, in memory it would look like this:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================

In an array, we know that each element is next to each other in memory. A C array (Called MyArray here) is simply a pointer to the first element:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^
MyArray

If we wanted to look up MyArray[4], internally it would be accessed like this:

   0     1     2     3     4 
=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
                           ^
MyArray + 4 ---------------/
(Pointer + Offset)

Because we can directly access any element in the array by adding the offset to the pointer, we can look up any element in the same amount of time, regardless of the size of the array. This means that getting MyArray[1000] would take the same amount of time as getting MyArray[5].

An alternative data structure is a linked list. This is a linear list of pointers, each pointing to the next node

========    ========    ========    ========    ========
| Data |    | Data |    | Data |    | Data |    | Data |
|      | -> |      | -> |      | -> |      | -> |      | 
|  P1  |    |  P2  |    |  P3  |    |  P4  |    |  P5  |        
========    ========    ========    ========    ========

P(X) stands for Pointer to next node.

Note that I made each "node" into its own block. This is because they are not guaranteed to be (and most likely won't be) adjacent in memory.

If I want to access P3, I can't directly access it, because I don't know where it is in memory. All I know is where the root (P1) is, so instead I have to start at P1, and follow each pointer to the desired node.

This is a O(N) look up time (The look up cost increases as each element is added). It is much more expensive to get to P1000 compared to getting to P4.

Higher level data structures, such as hashtables, stacks and queues, all may use an array (or multiple arrays) internally, while Linked Lists and Binary Trees usually use nodes and pointers.

You might wonder why anyone would use a data structure that requires linear traversal to look up a value instead of just using an array, but they have their uses.

Take our array again. This time, I want to find the array element that holds the value '5'.

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^     ^     ^     ^     ^   FOUND!

In this situation, I don't know what offset to add to the pointer to find it, so I have to start at 0, and work my way up until I find it. This means I have to perform 6 checks.

Because of this, searching for a value in an array is considered O(N). The cost of searching increases as the array gets larger.

Remember up above where I said that sometimes using a non sequential data structure can have advantages? Searching for data is one of these advantages and one of the best examples is the Binary Tree.

A Binary Tree is a data structure similar to a linked list, however instead of linking to a single node, each node can link to two children nodes.

         ==========
         |  Root  |         
         ==========
        /          \ 
  =========       =========
  | Child |       | Child |
  =========       =========
                  /       \
            =========    =========
            | Child |    | Child |
            =========    =========

 Assume that each connector is really a Pointer

When data is inserted into a binary tree, it uses several rules to decide where to place the new node. The basic concept is that if the new value is greater than the parents, it inserts it to the left, if it is lower, it inserts it to the right.

This means that the values in a binary tree could look like this:

         ==========
         |   100  |         
         ==========
        /          \ 
  =========       =========
  |  200  |       |   50  |
  =========       =========
                  /       \
            =========    =========
            |   75  |    |   25  |
            =========    =========

When searching a binary tree for the value of 75, we only need to visit 3 nodes ( O(log N) ) because of this structure:

• Is 75 less than 100? Look at Right Node
• Is 75 greater than 50? Look at Left Node
• There is the 75!

Even though there are 5 nodes in our tree, we did not need to look at the remaining two, because we knew that they (and their children) could not possibly contain the value we were looking for. This gives us a search time that at worst case means we have to visit every node, but in the best case we only have to visit a small portion of the nodes.

That is where arrays get beat, they provide a linear O(N) search time, despite O(1) access time.

This is an incredibly high level overview on data structures in memory, skipping over a lot of details, but hopefully it illustrates an array's strength and weakness compared to other data structures.

You could use the System.Web.UI.WebControls.CheckBoxList control or use the System.Web.UI.WebControls.ListBox control with the SelectionMode property set to Multiple.

row.IsNull("column")

you can try

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));

Document doc = db.parse(is);

You may see if you are not loading jQuery twice somehow. Especially after your plugin JavaScript file loaded.

I has the same error and found that one of my external PHP files was loading jQuery again.

For Spring Boot 2.3.3.RELEASE straight from Spring Initialzr:

POM: data jpa, h2, web

application properties: spring.h2.console.enabled=true

When you run the application look for line like below in the run console:

2020-08-18 21:12:32.664  INFO 63256 --- [           main] o.s.b.a.h2.H2ConsoleAutoConfiguration    : H2 console available at '/h2-console'. Database available at 'jdbc:h2:mem:eaa9d6da-aa2e-4ad3-9e5b-2b60eb2fcbc5'

Now use the above JDBC URL for h2-console and click on Connect.

The onClick attribute of html tags only takes Javascript but not PHP code. However, you can easily call a PHP function from within the Javascript code by using the JS document.write() function - effectively calling the PHP function by "writing" its call to the browser window: Eg.

onclick="document.write('<?php //call a PHP function here ?>');"

Your example:

    <?php
          function hello(){
              echo "Hello";
          }
    ?>

<input type="button" name="Release" onclick="document.write('<?php hello() ?>');" value="Click to Release">

JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.

JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.

Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.

Check the parse_string function http://php.net/manual/en/function.parse-str.php

It will return all the variables from a query string, including arrays.

Example from php.net:

<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz

parse_str($str, $output);
echo $output['first'];  // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz

?>

you can use servlet filter chain, but instead use the original one, you can create your own request yourownrequests extends HttpServletRequestWrapper.

I like s3fs which lets you use s3 (almost) like a local filesystem.

You can do this:

import s3fs

bytes_to_write = df.to_csv(None).encode()
fs = s3fs.S3FileSystem(key=key, secret=secret)
with fs.open('s3://bucket/path/to/file.csv', 'wb') as f:
    f.write(bytes_to_write)

s3fs supports only rb and wb modes of opening the file, that's why I did this bytes_to_write stuff.

Remember that ConfigurationManager uses only one app.config - one that is in startup project.

If you put some app.config to a solution A and make a reference to it from another solution B then if you run B, app.config from A will be ignored.

So for example unit test project should have their own app.config.

For jQuery (at least version 1.11.2) the following procedure worked for me.

1. Right click on the element and open 'Chrome Developer Tools'
2. Type $._data(($0), 'events'); in the 'Console'
3. Expand the attached objects and double click the handler: value.
4. This shows the source code of the attached function, search for part of that using the 'Search' tab.

And it's time to stop re-inventing the wheel and start using vanilla JS events ... :)

my issue was (master|REBASE 1/1)

this command worked for me

 git rebase --skip

Well you understood it partially. You have to tailor the beans according to your need and inform Spring container to manage it when required, by using a methodology populalrly known as IoC (Inversion of Control) coined by Martin Fowler, also known as Dependency Injection (DI).

You wire the beans in a way, so that you do not have to take care of the instantiating or evaluate any dependency on the bean. This is popularly known as Hollywood Principle.

Google is the best tool to explore more on this in addition to the links you would get flooded with here in this question. :)

string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);

If you have a single character delimiter (like for instance ,), you can reduce that to (note the single quotes):

string[] tokens = str.Split(',');

" is on the official list of valid HTML 4 entities, but ' is not.

From C.16. The Named Character Reference ':

The named character reference ' (the apostrophe, U+0027) was introduced in XML 1.0 but does not appear in HTML. Authors should therefore use ' instead of ' to work as expected in HTML 4 user agents.

I had this problem when trying to run 'npm install' in a Terminal window which had been opened before installing Node.js.

Opening a new Terminal window (i.e. bash session) worked. (Presumably this provided the correct environment variables for npm to run correctly.)

data <- data[-which(data[,1] %in% c("b","d","e")),]

input[type="checkbox"] {
 /* your style */
}

But this will only work for browsers except IE7 and below, for those you will have to use a class.

I had the same issue when updating an older project. Here's what I did to resolve it:

• Converted all projects to .NET 4.5.
• Uninstalled the NuGet package for Entity Framework 5.
• Reinstalled the NuGet package for Entity Framework 5.
• Cleaned the solution.
• Rebuilt the solution.

The projects that used Entity Framework 5 and .NET 4 were installing the Entity Framework dll version 4.4. Once I switched the .NET version to 4.5 on the project, the dll version would be 5.

My problem came from older projects being on .NET 4 and a newer project running .NET 4.5 so there were 2 dll versions of EF in my solution.

Hope this helps someone...

UPDATE

By Android Support Library 23.2 update, all WRAP_CONTENT should work correctly.

Please update version of a library in gradle file.

compile 'com.android.support:recyclerview-v7:23.2.0'

Original Answer

As answered on other question, you need to use original onMeasure() method when your recycler view height is bigger than screen height. This layout manager can calculate ItemDecoration and can scroll with more.

    public class MyLinearLayoutManager extends LinearLayoutManager {

public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout)    {
    super(context, orientation, reverseLayout);
}

private int[] mMeasuredDimension = new int[2];

@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    final int widthMode = View.MeasureSpec.getMode(widthSpec);
    final int heightMode = View.MeasureSpec.getMode(heightSpec);
    final int widthSize = View.MeasureSpec.getSize(widthSpec);
    final int heightSize = View.MeasureSpec.getSize(heightSpec);
    int width = 0;
    int height = 0;
    for (int i = 0; i < getItemCount(); i++) {
        measureScrapChild(recycler, i,
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                mMeasuredDimension);

        if (getOrientation() == HORIZONTAL) {
            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }

    // If child view is more than screen size, there is no need to make it wrap content. We can use original onMeasure() so we can scroll view.
    if (height < heightSize && width < widthSize) {

        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    } else {
        super.onMeasure(recycler, state, widthSpec, heightSpec);
    }
}

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {

   View view = recycler.getViewForPosition(position);

   // For adding Item Decor Insets to view
   super.measureChildWithMargins(view, 0, 0);
    if (view != null) {
        RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();

Thanks guys, I was migrating an existing project to Gradle and didn't like the idea of changing the project structure that much.

I have figured it out, thought this information could be useful to beginners.

Here is a sample task from my 'build.gradle':

version = '1.0.0'

jar {
   baseName = 'analytics'
   from('src/main/java') {
      include 'config/**/*.xml'
   }

   manifest {
       attributes 'Implementation-Title': 'Analytics Library', 'Implementation-Version': version
   }
}

It depends on what function you want to run. If you need something done on server side, like querying a database or setting something in the session or anything that can not be done on client side, you need AJAX, else you can do it on client-side with JavaScript. Don't make the server work when you can do what you need to do on client side.

jQuery provides an easy way to do ajax : http://api.jquery.com/jQuery.ajax/

Without more details as to what the question is exactly asking, I am going to answer the title of the question,

Create an Array:

String[] myArray = new String[2];
int[] intArray = new int[2];

// or can be declared as follows
String[] myArray = {"this", "is", "my", "array"};
int[] intArray = {1,2,3,4};

Create an ArrayList:

ArrayList<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("World");

ArrayList<Integer> myNum = new ArrayList<Integer>();
myNum.add(1);
myNum.add(2);

This means, create an ArrayList of String and Integer objects. You cannot use int because thats a primitive data types, see the link for a list of primitive data types.

Create a Stack:

Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);

Create an Queue: (using LinkedList)

Queue<String> myQueue = new LinkedList<String>();
Queue<Integer> myNumbers = new LinkedList<Integer>();
myQueue.add("Hello");
myQueue.add("World");
myNumbers.add(1);
myNumbers.add(2);

Same thing as an ArrayList, this declaration means create an Queue of String and Integer objects.

Update:

In response to your comment from the other given answer,

i am pretty confused now, why are using string. and what does <String> means

We are using String only as a pure example, but you can add any other object, but the main point is that you use an object not a primitive type. Each primitive data type has their own primitive wrapper class, see link for list of primitive data type's wrapper class.

I have posted some links to explain the difference between the two, but here are a list of primitive types

• byte
• short
• char
• int
• long
• boolean
• double
• float

Which means, you are not allowed to make an ArrayList of integer's like so:

ArrayList<int> numbers = new ArrayList<int>(); 
           ^ should be an object, int is not an object, but Integer is!
ArrayList<Integer> numbers = new ArrayList<Integer>();
            ^ perfectly valid

Also, you can use your own objects, here is my Monster object I created,

public class Monster {
   String name = null;
   String location = null;
   int age = 0;

public Monster(String name, String loc, int age) { 
   this.name = name;
   this.loc = location;
   this.age = age;
 }

public void printDetails() {
   System.out.println(name + " is from " + location +
                                     " and is " + age + " old.");
 }
} 

Here we have a Monster object, but now in our Main.java class we want to keep a record of all our Monster's that we create, so let's add them to an ArrayList

public class Main {
    ArrayList<Monster> myMonsters = new ArrayList<Monster>();

public Main() {
    Monster yetti = new Monster("Yetti", "The Mountains", 77);
    Monster lochness = new Monster("Lochness Monster", "Scotland", 20);

    myMonsters.add(yetti); // <-- added Yetti to our list
    myMonsters.add(lochness); // <--added Lochness to our list
  
    for (Monster m : myMonsters) {
        m.printDetails();
     }
   }

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

(I helped my girlfriend's brother with a Java game, and he had to do something along those lines as well, but I hope the example was well demonstrated)

It could also be that the button needs to have CausesValidation="false". That worked for me.

File Comparer VS Extension by Akhil Mittal. Excellent lightweight tool that gets the job done.

In Case of password also we need to pass one more parameter

redis-cli -h host -p port -a password

Sometimes even the simplest things can make a difference. One of these simple items that should be part of every stored procedure is SET NOCOUNT ON. This one line of code, put at the top of a stored procedure turns off the messages that SQL Server sends back to the client after each T-SQL statement is executed. This is performed for all SELECT, INSERT, UPDATE, and DELETE statements. Having this information is handy when you run a T-SQL statement in a query window, but when stored procedures are run there is no need for this information to be passed back to the client.

By removing this extra overhead from the network it can greatly improve overall performance for your database and application.

If you still need to get the number of rows affected by the T-SQL statement that is executing you can still use the @@ROWCOUNT option. By issuing a SET NOCOUNT ON this function (@@ROWCOUNT) still works and can still be used in your stored procedures to identify how many rows were affected by the statement.

for classes you can use:

div[class^="jander"]

After you get an error, in the next cell just run %debug and that's it.

I had the same problem then I found that I wasn´t hitting the node server command in the proper directory where the server.js is located.

Hope this helps.

In my case I have had similar error message:

The 'ObjectContent`1' type failed to serialize the response body for content type 'application/xml; charset=utf-8'.

But when I dig deeper in it, the issue was:

Type 'name.SomeSubRootType' with data contract name 'SomeSubRootType://schemas.datacontract.org/2004/07/WhatEverService' is not expected. Consider using a DataContractResolver if you are using DataContractSerializer or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to the serializer.

The way I solved by adding KnownType.

[KnownType(typeof(SomeSubRootType))]
public partial class SomeRootStructureType

This was solved inspired from this answer.

@ is used as a prefix denoting stored procedure and function parameter names, and also variable names

Go to Start and search for "Anaconda Prompt" - right click this and choose "Open File Location", which will open a folder of shortcuts. Right click the "Anaconda Prompt" shortcut, choose "Properties" and you can adjust the starting dir in the "Start in" box.

First off:

public class ProfileCollection implements Iterable<Profile> {

Second:

return m_Profiles.get(m_ActiveProfile);

I can see what @Þaw mentioned :

$ENROLLEES = $this->load->database('ENROLLEES', TRUE);
$ACCOUNTS = $this->load->database('ACCOUNTS', TRUE);

CodeIgniter supports multiple databases. You need to keep both database reference in separate variable as you did above. So far you are right/correct.

Next you need to use them as below:

$ENROLLEES->query();
$ENROLLEES->result();

and

$ACCOUNTS->query();
$ACCOUNTS->result();

Instead of using

$this->db->query();
$this->db->result();

See this for reference: http://ellislab.com/codeigniter/user-guide/database/connecting.html

Use negative lookahead:

^(?!.*ab).*$

UPDATE: In the comments below, I stated that this approach is slower than the one given in Peter's answer. I've run some tests since then, and found that it's really slightly faster. However, the reason to prefer this technique over the other is not speed, but simplicity.

The other technique, described here as a tempered greedy token, is suitable for more complex problems, like matching delimited text where the delimiters consist of multiple characters (like HTML, as Luke commented below). For the problem described in the question, it's overkill.

For anyone who's interested, I tested with a large chunk of Lorem Ipsum text, counting the number of lines that don't contain the word "quo". These are the regexes I used:

(?m)^(?!.*\bquo\b).+$

(?m)^(?:(?!\bquo\b).)+$

Whether I search for matches in the whole text, or break it up into lines and match them individually, the anchored lookahead consistently outperforms the floating one.

HashSet hs = new HashSet();
                hs.addAll(arrayList);
                arrayList.clear();
                arrayList.addAll(hs);

You can add more key value pair in the same object without replacing old ones in following way:

var obj = {};

obj = {
"1": "aa",
"2": "bb"
};

obj["3"] = "cc";

Below is the code and jsfiddle link to sample demo that will add more key value pairs to the already existed obj on clicking of button:

var obj = {
    "1": "aa",
    "2": "bb"
};

var noOfItems = Object.keys(obj).length;

$('#btnAddProperty').on('click', function() {
    noOfItems++;
    obj[noOfItems] = $.trim($('#txtName').val());
    console.log(obj);
});

Use double quotes:

$i = 1;
echo "
<p class=\"paragraph$i\">
</p>
";
++i;

You can limit the depth of the history while cloning:

--depth <depth>
Create a shallow clone with a history truncated to the specified 
number of revisions.

Use this if you want limited history, but still some.

Here is an example using RSA.

Important: There is a limit to the size of data you can encrypt with the RSA encryption, KeySize - MinimumPadding. e.g. 256 bytes (assuming 2048 bit key) - 42 bytes (min OEAP padding) = 214 bytes (max plaintext size)

Replace your_rsa_key with your RSA key.

var provider = new System.Security.Cryptography.RSACryptoServiceProvider();
provider.ImportParameters(your_rsa_key);

var encryptedBytes = provider.Encrypt(
    System.Text.Encoding.UTF8.GetBytes("Hello World!"), true);

string decryptedTest = System.Text.Encoding.UTF8.GetString(
    provider.Decrypt(encryptedBytes, true));

You have used some type errors. If you want to set 08/16/2011 to following pattern. It is wrong because,

mm stands for minutes, use MM as it is for Months

DD is wrong, it should be dd which represents Days

Try this to achieve the output you want to get ( Tue Aug 16 "Whatever Time" IST 2011 ),

    String date = "08/16/2011"; //input date as String

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy"); // date pattern

    Date myDate = simpleDateFormat.parse(date); // returns date object 

    System.out.println(myDate); //outputs: Tue Aug 16 00:00:00 IST 2011

This error was caused, for me, by different circumstances. A downloaded project tutorial had a default setting of [Project]>Targets>Build Settings>Architectures>Build Active Architecture Only>Release = "Yes." I wasn't intending to build a release, so the solution was to set Release (which presumably requires not just a developer profile but distribution profile) to "No."

in the head section add

<script src="fileName.js"></script>
