I got the errors to go away by installing the Windows Universal CRT SDK component, which adds support for legacy Windows SDKs. You can install this using the Visual Studio Installer:

If the problem still persists, you should change the Target SDK in the Visual Studio Project : check whether the Windows SDK version is 10.0.15063.0.

In : Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0.

Then errno.h and other standard files will be found and it will compile.

From comments:

But, this code never stops (because of integer overflow) !?! Yves Daoust

For many numbers it will not overflow.

If it will overflow - for one of those unlucky initial seeds, the overflown number will very likely converge toward 1 without another overflow.

Still this poses interesting question, is there some overflow-cyclic seed number?

Any simple final converging series starts with power of two value (obvious enough?).

2^64 will overflow to zero, which is undefined infinite loop according to algorithm (ends only with 1), but the most optimal solution in answer will finish due to shr rax producing ZF=1.

Can we produce 2^64? If the starting number is 0x5555555555555555, it's odd number, next number is then 3n+1, which is 0xFFFFFFFFFFFFFFFF + 1 = 0. Theoretically in undefined state of algorithm, but the optimized answer of johnfound will recover by exiting on ZF=1. The cmp rax,1 of Peter Cordes will end in infinite loop (QED variant 1, "cheapo" through undefined 0 number).

How about some more complex number, which will create cycle without 0? Frankly, I'm not sure, my Math theory is too hazy to get any serious idea, how to deal with it in serious way. But intuitively I would say the series will converge to 1 for every number : 0 < number, as the 3n+1 formula will slowly turn every non-2 prime factor of original number (or intermediate) into some power of 2, sooner or later. So we don't need to worry about infinite loop for original series, only overflow can hamper us.

So I just put few numbers into sheet and took a look on 8 bit truncated numbers.

There are three values overflowing to 0: 227, 170 and 85 (85 going directly to 0, other two progressing toward 85).

But there's no value creating cyclic overflow seed.

Funnily enough I did a check, which is the first number to suffer from 8 bit truncation, and already 27 is affected! It does reach value 9232 in proper non-truncated series (first truncated value is 322 in 12th step), and the maximum value reached for any of the 2-255 input numbers in non-truncated way is 13120 (for the 255 itself), maximum number of steps to converge to 1 is about 128 (+-2, not sure if "1" is to count, etc...).

Interestingly enough (for me) the number 9232 is maximum for many other source numbers, what's so special about it? :-O 9232 = 0x2410 ... hmmm.. no idea.

Unfortunately I can't get any deep grasp of this series, why does it converge and what are the implications of truncating them to k bits, but with cmp number,1 terminating condition it's certainly possible to put the algorithm into infinite loop with particular input value ending as 0 after truncation.

But the value 27 overflowing for 8 bit case is sort of alerting, this looks like if you count the number of steps to reach value 1, you will get wrong result for majority of numbers from the total k-bit set of integers. For the 8 bit integers the 146 numbers out of 256 have affected series by truncation (some of them may still hit the correct number of steps by accident maybe, I'm too lazy to check).

Use JSON.stringify() to wrap your json

var parameter = JSON.stringify({type:"user", username:user_email, password:user_password});
    $http.post(url, parameter).
    success(function(data, status, headers, config) {
        // this callback will be called asynchronously
        // when the response is available
        console.log(data);
      }).
      error(function(data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
      });

Try this simple solution to convert file to base64 string

String base64String = imageFileToByte(file);

public String imageFileToByte(File file){

    Bitmap bm = BitmapFactory.decodeFile(file.getAbsolutePath());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
    byte[] b = baos.toByteArray();
    return Base64.encodeToString(b, Base64.DEFAULT);
}

Another good way of dealing with Lion's hidden scroll bars is to display a prompt to scroll down. It doesn't work with small scroll areas such as text fields but well with large scroll areas and keeps the overall style of the site. One site doing this is http://versusio.com, just check this example page and wait 1.5 seconds to see the prompt:

http://versusio.com/en/samsung-galaxy-nexus-32gb-vs-apple-iphone-4s-64gb

The implementation isn't hard but you have to take care, that you don't display the prompt when the user has already scrolled.

You need jQuery + Underscore and

$(window).scroll to check if the user already scrolled by himself,

_.delay() to trigger a delay before you display the prompt -- the prompt shouldn't be to obtrusive

$('#prompt_div').fadeIn('slow') to fade in your prompt and of course

$('#prompt_div').fadeOut('slow') to fade out when the user scrolled after he saw the prompt

In addition, you can bind Google Analytics events to track user's scrolling behavior.

Try change _DEBUG to NDEBUG macro definition in C++ project properties (for Release configuration) Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions

Simple:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

[Update]
I've just realized why you weren't receiving results back... you have a missing line in your Deserialize method. You were forgetting to assign the results to your obj :

public static T Deserialize<T>(string json)
{
    using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
    {
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
        return (T)serializer.ReadObject(ms);
    } 
}

Also, just for reference, here is the Serialize method :

public static string Serialize<T>(T obj)
{
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    using (MemoryStream ms = new MemoryStream())
    {
        serializer.WriteObject(ms, obj);
        return Encoding.Default.GetString(ms.ToArray());
    }
}

Edit

If you want to use Json.NET here are the equivalent Serialize/Deserialize methods to the code above..

Deserialize:

JsonConvert.DeserializeObject<T>(string json);

Serialize:

JsonConvert.SerializeObject(object o);

This are already part of Json.NET so you can just call them on the JsonConvert class.

Link: Serializing and Deserializing JSON with Json.NET

Now, the reason you're getting a StackOverflow is because of your Properties.

Take for example this one :

[DataMember]
public string unescapedUrl
{
    get { return unescapedUrl; } // <= this line is causing a Stack Overflow
    set { this.unescapedUrl = value; }
}

Notice that in the getter, you are returning the actual property (ie the property's getter is calling itself over and over again), and thus you are creating an infinite recursion.

Properties (in 2.0) should be defined like such :

string _unescapedUrl; // <= private field

[DataMember]
public string unescapedUrl
{
    get { return _unescapedUrl; } 
    set { _unescapedUrl = value; }
}

You have a private field and then you return the value of that field in the getter, and set the value of that field in the setter.

Btw, if you're using the 3.5 Framework, you can just do this and avoid the backing fields, and let the compiler take care of that :

public string unescapedUrl { get; set;}

Date -> LocalDate:

LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();

LocalDate -> Date:

Date date = Date.from(localDate.atStartOfDay(ZoneId.systemDefault()).toInstant());

In some circumstances it might be useful to simply remove the bindings and then re-apply:

ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))

For anyone looking for quick working code, try this:

I wrote a function lcm_n(args, num) which computes and returns the lcm of all the numbers in the array args. The second parameternum is the count of numbers in the array.

Put all those numbers in an array args and then call the function like lcm_n(args,num);

This function returns the lcm of all those numbers.

Here is the implementation of the function lcm_n(args, num):

int lcm_n(int args[], int num) //lcm of more than 2 numbers
{
    int i, temp[num-1];

    if(num==2)
    {
        return lcm(args[0], args[1]);
    }
    else
    {
        for(i=0;i<num-1;i++)
        {
           temp[i] = args[i];   
        }

        temp[num-2] = lcm(args[num-2], args[num-1]);
        return lcm_n(temp,num-1);
    }
}

This function needs below two functions to work. So, just add them along with it.

int lcm(int a, int b) //lcm of 2 numbers
{
    return (a*b)/gcd(a,b);
}


int gcd(int a, int b) //gcd of 2 numbers
{
    int numerator, denominator, remainder;

    //Euclid's algorithm for computing GCD of two numbers
    if(a > b)
    {
        numerator = a;
        denominator = b;
    }
    else
    {
        numerator = b;
        denominator = a;
    }
    remainder = numerator % denominator;

    while(remainder != 0)
    {
        numerator   = denominator;
        denominator = remainder;
        remainder   = numerator % denominator;
    }

    return denominator;
}

This blog post explains it perfectly: Ruby's Exception vs StandardError: What's the difference?

Why you shouldn't rescue Exception

The problem with rescuing Exception is that it actually rescues every exception that inherits from Exception. Which is....all of them!

That's a problem because there are some exceptions that are used internally by Ruby. They don't have anything to do with your app, and swallowing them will cause bad things to happen.

Here are a few of the big ones:

• SignalException::Interrupt - If you rescue this, you can't exit your app by hitting control-c.

• ScriptError::SyntaxError - Swallowing syntax errors means that things like puts("Forgot something) will fail silently.

• NoMemoryError - Wanna know what happens when your program keeps running after it uses up all the RAM? Me neither.

begin
  do_something()
rescue Exception => e
  # Don't do this. This will swallow every single exception. Nothing gets past it. 
end

I'm guessing that you don't really want to swallow any of these system-level exceptions. You only want to catch all of your application level errors. The exceptions caused YOUR code.

Luckily, there's an easy way to to this.

Rescue StandardError Instead

All of the exceptions that you should care about inherit from StandardError. These are our old friends:

NoMethodError - raised when you try to invoke a method that doesn't exist

TypeError - caused by things like 1 + ""

RuntimeError - who could forget good old RuntimeError?

To rescue errors like these, you'll want to rescue StandardError. You COULD do it by writing something like this:

begin
  do_something()
rescue StandardError => e
  # Only your app's exceptions are swallowed. Things like SyntaxErrror are left alone. 
end

But Ruby has made it much easier for use.

When you don't specify an exception class at all, ruby assumes you mean StandardError. So the code below is identical to the above code:

begin
  do_something()
rescue => e
  # This is the same as rescuing StandardError
end

For connecting to a sql server database via Windows authentication basically needs which server you want to connect , what is your database name , Integrated Security info and provider name.

Basically this works:

<connectionStrings>      
<add name="MyConnectionString"
         connectionString="data source=ServerName;
   Initial Catalog=DatabaseName;Integrated Security=True;"
         providerName="System.Data.SqlClient" />
</connectionStrings> 

Setting Integrated Security field true means basically you want to reach database via Windows authentication, if you set this field false Windows authentication will not work.

It is also working different according which provider you are using.

• SqlClient both Integrated Security=true; or IntegratedSecurity=SSPI; is working.

• OleDb it is Integrated Security=SSPI;

• Odbc it is Trusted_Connection=yes;
• OracleClient it is Integrated Security=yes;

Integrated Security=true throws an exception when used with the OleDb provider.

Unlike centralized version control systems, Git clones the entire repository, so you don't only get the current remote files, but the whole history. You local repository will include all this.

There might have been tags to mark a particular version at the time. If not, you can create them yourself locally. A good way to do this is to use git log or perhaps more visually with tools like gitk (perhaps gitk --all to see all the branches and tags). If you can spot the commits hashes that were used at the time, you can tag them using git tag <hash> and then check those out in new working copies (for example git checkout -b new_branch_name tag_name or directly with the hash instead of the tag name).

There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.

Your code could look like this:

<script>
    var count = 1;
    function setColor(btn, color) {
        var property = document.getElementById(btn);
        if (count == 0) {
            property.style.backgroundColor = "#FFFFFF"
            count = 1;        
        }
        else {
            property.style.backgroundColor = "#7FFF00"
            count = 0;
        }
    }
</script>

Hope this helps.

Demo : http://jsfiddle.net/NbGBj/

$("document").ready(function(){

    $("#upload").change(function() {
        alert('changed!');
    });
});

This produces a nice effect.

<div style="border: 1px solid gray; padding: 1px">
<div style="border: 1px solid gray">
   internal stuff
</div>
</div>

This kind of error can be caused by LF vs CRLF line ending mismatches, e.g. when you're looking at the patch file and you're absolutely sure it should be able to apply, but it just won't.

To test this out, if you have a patch that applies to just one file, you can try running 'unix2dos' or 'dos2unix' on just that file (try both, to see which one causes the file to change; you can get these utilities for Windows as well as Unix), then commit that change as a test commit, then try applying the patch again. If that works, that was the problem.

NB git am applies patches as LF by default (even if the patch file contains CRLF), so if you want to apply CRLF patches to CRLF files you must use git am --keep-cr, as per this answer.

this should work:

for numbers, strings, date, etc.:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;

            Dictionary<string, string> newDict = new Dictionary<string, string>();
            foreach (object key in idict.Keys)
            {
                newDict.Add(key.ToString(), idict[key].ToString());
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

if your dictionary also contains some other objects:

    public static void MyMethod(object obj)
    {
        if (typeof(IDictionary).IsAssignableFrom(obj.GetType()))
        {
            IDictionary idict = (IDictionary)obj;
            Dictionary<string, string> newDict = new Dictionary<string, string>();

            foreach (object key in idict.Keys)
            {
                newDict.Add(objToString(key), objToString(idict[key]));
            }
        }
        else
        {
            // My object is not a dictionary
        }
    }

    private static string objToString(object obj)
    {
        string str = "";
        if (obj.GetType().FullName == "System.String")
        {
            str = (string)obj;
        }
        else if (obj.GetType().FullName == "test.Testclass")
        {
            TestClass c = (TestClass)obj;
            str = c.Info;
        }
        return str;
    }

You can do it manually. (I know, that that isn't great solution, but..) use while loop till the result hasn't a value

kickOff().then(function(result) {
   while(true){
       if (result === undefined) continue;
       else {
            $("#output").append(result);
            return;
       }
   }
});

chmod +w <directory>

I'd also recommend looking at chpst (part of runit):

chpst -L /tmp/your-lockfile.loc ./script.name.sh

Compressed GZipStream objects written to a file with an extension of .gz can be decompressed using many common compression tools; however, this class does not inherently provide functionality for adding files to or extracting files from .zip archives.

A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

I seem to have a blind spot as regards your html structure, but I think that this is what you're looking for. It should find the currently-selected option from the select input, assign its text to the newVal variable and then apply that variable to the value attribute of the #costLabel label:

jQuery

$(document).ready(
  function() {
    $('select[name=package]').change(
      function(){
        var newText = $('option:selected',this).text();
        $('#costLabel').text('Total price: ' + newText);
      }
      );
  }
  );

html:

  <form name="thisForm" id="thisForm" action="#" method="post">
  <fieldset>
    <select name="package" id="package">
        <option value="standard">Standard - &euro;55 Monthly</option>
        <option value="standardAnn">Standard - &euro;49 Monthly</option>            
        <option value="premium">Premium - &euro;99 Monthly</option>
        <option value="premiumAnn" selected="selected">Premium - &euro;89 Monthly</option>            
        <option value="platinum">Platinum - &euro;149 Monthly</option>
        <option value="platinumAnn">Platinum - &euro;134 Monthly</option>   
    </select>
  </fieldset>
    
    <fieldset>
      <label id="costLabel" name="costLabel">Total price: </label>
    </fieldset>
  </form>

Working demo of the above at: JS Bin

You can use an IF statement to check the referenced cell(s) and return one result for zero or blank, and otherwise return your formula result.

A simple example:

=IF(B1=0;"";A1/B1)

This would return an empty string if the divisor B1 is blank or zero; otherwise it returns the result of dividing A1 by B1.

In your case of running an average, you could check to see whether or not your data set has a value:

=IF(SUM(K23:M23)=0;"";AVERAGE(K23:M23))

If there is nothing entered, or only zeros, it returns an empty string; if one or more values are present, you get the average.

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

This method will get properties of the class and compare the values for each property. If any of the values are different, it will return false, else it will return true.

public static bool Compare<T>(T Object1, T object2)
{
    //Get the type of the object
    Type type = typeof(T);

    //return false if any of the object is false
    if (Object1 == null || object2 == null)
        return false;

    //Loop through each properties inside class and get values for the property from both the objects and compare
    foreach (System.Reflection.PropertyInfo property in type.GetProperties())
    {
        if (property.Name != "ExtensionData")
        {
            string Object1Value = string.Empty;
            string Object2Value = string.Empty;
            if (type.GetProperty(property.Name).GetValue(Object1, null) != null)
                Object1Value = type.GetProperty(property.Name).GetValue(Object1, null).ToString();
            if (type.GetProperty(property.Name).GetValue(object2, null) != null)
                Object2Value = type.GetProperty(property.Name).GetValue(object2, null).ToString();
            if (Object1Value.Trim() != Object2Value.Trim())
            {
                return false;
            }
        }
    }
    return true;
}

Usage:

bool isEqual = Compare<Employee>(Object1, Object2)

a {background-color:transparent !important;}

Since no one else said it, the short-cut to compile (build) a C# app in Visual Studio Code (VSCode) is SHIFT+CTRL+B.

If you want to see the build errors (because they don't pop-up by default), the shortcut is SHIFT+CTRL+M.

(I know this question was asking for more than just the build shortcut. But I wanted to answer the question in the title, which wasn't directly answered by other answers/comments.)

What is SQL JOIN ?

SQL JOIN is a method to retrieve data from two or more database tables.

What are the different SQL JOINs ?

There are a total of five JOINs. They are :

  1. JOIN or INNER JOIN
  2. OUTER JOIN

     2.1 LEFT OUTER JOIN or LEFT JOIN
     2.2 RIGHT OUTER JOIN or RIGHT JOIN
     2.3 FULL OUTER JOIN or FULL JOIN

  3. NATURAL JOIN
  4. CROSS JOIN
  5. SELF JOIN

1. JOIN or INNER JOIN :

In this kind of a JOIN, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.

In other words, INNER JOIN is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.

Note that a JOIN without any other JOIN keywords (like INNER, OUTER, LEFT, etc) is an INNER JOIN. In other words, JOIN is a Syntactic sugar for INNER JOIN (see: Difference between JOIN and INNER JOIN).

2. OUTER JOIN :

OUTER JOIN retrieves

Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).

There are three kinds of Outer Join :

2.1 LEFT OUTER JOIN or LEFT JOIN

This join returns all the rows from the left table in conjunction with the matching rows from the right table. If there are no columns matching in the right table, it returns NULL values.

2.2 RIGHT OUTER JOIN or RIGHT JOIN

This JOIN returns all the rows from the right table in conjunction with the matching rows from the left table. If there are no columns matching in the left table, it returns NULL values.

2.3 FULL OUTER JOIN or FULL JOIN

This JOIN combines LEFT OUTER JOIN and RIGHT OUTER JOIN. It returns rows from either table when the conditions are met and returns NULL value when there is no match.

In other words, OUTER JOIN is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.

Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.

3. NATURAL JOIN :

It is based on the two conditions :

1. the JOIN is made on all the columns with the same name for equality.
2. Removes duplicate columns from the result.

This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.

4. CROSS JOIN :

It is the Cartesian product of the two tables involved. The result of a CROSS JOIN will not make sense in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).

5. SELF JOIN :

It is not a different form of JOIN, rather it is a JOIN (INNER, OUTER, etc) of a table to itself.

JOINs based on Operators

Depending on the operator used for a JOIN clause, there can be two types of JOINs. They are

1. Equi JOIN
2. Theta JOIN

1. Equi JOIN :

For whatever JOIN type (INNER, OUTER, etc), if we use ONLY the equality operator (=), then we say that the JOIN is an EQUI JOIN.

2. Theta JOIN :

This is same as EQUI JOIN but it allows all other operators like >, <, >= etc.

Many consider both EQUI JOIN and Theta JOIN similar to INNER, OUTER etc JOINs. But I strongly believe that its a mistake and makes the ideas vague. Because INNER JOIN, OUTER JOIN etc are all connected with the tables and their data whereas EQUI JOIN and THETA JOIN are only connected with the operators we use in the former.

Again, there are many who consider NATURAL JOIN as some sort of "peculiar" EQUI JOIN. In fact, it is true, because of the first condition I mentioned for NATURAL JOIN. However, we don't have to restrict that simply to NATURAL JOINs alone. INNER JOINs, OUTER JOINs etc could be an EQUI JOIN too.

In C, a "stream" is an abstraction; from the program's perspective it is simply a producer (input stream) or consumer (output stream) of bytes. It can correspond to a file on disk, to a pipe, to your terminal, or to some other device such as a printer or tty. The FILE type contains information about the stream. Normally, you don't mess with a FILE object's contents directly, you just pass a pointer to it to the various I/O routines.

There are three standard streams: stdin is a pointer to the standard input stream, stdout is a pointer to the standard output stream, and stderr is a pointer to the standard error output stream. In an interactive session, the three usually refer to your console, although you can redirect them to point to other files or devices:

$ myprog < inputfile.dat > output.txt 2> errors.txt

In this example, stdin now points to inputfile.dat, stdout points to output.txt, and stderr points to errors.txt.

fprintf writes formatted text to the output stream you specify.

printf is equivalent to writing fprintf(stdout, ...) and writes formatted text to wherever the standard output stream is currently pointing.

sprintf writes formatted text to an array of char, as opposed to a stream.

Extended sort key columns

The reason why what you want to do doesn't work is because of the logical order of operations in SQL, which, for your first query, is (simplified):

• FROM MonitoringJob
• SELECT Category, CreationDate i.e. add a so called extended sort key column
• ORDER BY CreationDate DESC
• SELECT Category i.e. remove the extended sort key column again from the result.

So, thanks to the SQL standard extended sort key column feature, it is totally possible to order by something that is not in the SELECT clause, because it is being temporarily added to it behind the scenes.

So, why doesn't this work with DISTINCT?

If we add the DISTINCT operation, it would be added between SELECT and ORDER BY:

• FROM MonitoringJob
• SELECT Category, CreationDate
• DISTINCT
• ORDER BY CreationDate DESC
• SELECT Category

But now, with the extended sort key column CreationDate, the semantics of the DISTINCT operation has been changed, so the result will no longer be the same. This is not what we want, so both the SQL standard, and all reasonable databases forbid this usage.

Workarounds

It can be emulated with standard syntax as follows

SELECT Category
FROM (
  SELECT Category, MAX(CreationDate) AS CreationDate
  FROM MonitoringJob
  GROUP BY Category
) t
ORDER BY CreationDate DESC

Or, just simply (in this case), as shown also by Prutswonder

SELECT Category, MAX(CreationDate) AS CreationDate
FROM MonitoringJob
GROUP BY Category
ORDER BY CreationDate DESC

I have blogged about SQL DISTINCT and ORDER BY more in detail here.

I downloaded a different installer "SQL Server 2014 Express with Advanced Services" and found Instance Features in it. Thanks for Alberto Solano's answer, it was really helpful.

My first installer was "SQL Server 2014 Express". It installed only SQL Management Studio and tools without Instance features. After installation "SQL Server 2014 Express with Advanced Services" my LocalDB is now alive!!!

Add onload listener in componentDidMount

class Comp1 extends React.Component {
 constructor(props) {
    super(props);
    this.handleLoad = this.handleLoad.bind(this);
 }

 componentDidMount() {
    window.addEventListener('load', this.handleLoad);
 }

 componentWillUnmount() { 
   window.removeEventListener('load', this.handleLoad)  
 }

 handleLoad() {
  $("myclass") //  $ is available here
 }
}

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

At regular intervals, I am adding new lines of text to it. I would like the textbox to automatically scroll to the bottom-most entry (the newest one) whenever a new line is added.

If you use TextBox.AppendText(string text), it will automatically scroll to the end of the newly appended text. It avoids the flickering scrollbar if you're calling it in a loop.

It also happens to be an order of magnitude faster than concatenating onto the .Text property. Though that might depend on how often you're calling it; I was testing with a tight loop.

This will not scroll if it is called before the textbox is shown, or if the textbox is otherwise not visible (e.g. in a different tab of a TabPanel). See TextBox.AppendText() not autoscrolling. This may or may not be important, depending on if you require autoscroll when the user can't see the textbox.

It seems that the alternative method from the other answers also don't work in this case. One way around it is to perform additional scrolling on the VisibleChanged event:

textBox.VisibleChanged += (sender, e) =>
{
    if (textBox.Visible)
    {
        textBox.SelectionStart = textBox.TextLength;
        textBox.ScrollToCaret();
    }
};

Internally, AppendText does something like this:

textBox.Select(textBox.TextLength + 1, 0);
textBox.SelectedText = textToAppend;

But there should be no reason to do it manually.

^{(If you decompile it yourself, you'll see that it uses some possibly more efficient internal methods, and has what seems to be a minor special case.)}

The problem by using stream().forEach(..) with a call to add or put inside the forEach (so you mutate the external myMap or myList instance) is that you can run easily into concurrency issues if someone turns the stream in parallel and the collection you are modifying is not thread safe.

One approach you can take is to first partition the entries in the original map. Once you have that, grab the corresponding list of entries and collect them in the appropriate map and list.

Map<Boolean, List<Map.Entry<K, V>>> partitions =
    animalMap.entrySet()
             .stream()
             .collect(partitioningBy(e -> e.getValue() == null));

Map<K, V> myMap = 
    partitions.get(false)
              .stream()
              .collect(toMap(Map.Entry::getKey, Map.Entry::getValue));

List<K> myList =
    partitions.get(true)
              .stream()
              .map(Map.Entry::getKey) 
              .collect(toList());

... or if you want to do it in one pass, implement a custom collector (assuming a Tuple2<E1, E2> class exists, you can create your own), e.g:

public static <K,V> Collector<Map.Entry<K, V>, ?, Tuple2<Map<K, V>, List<K>>> customCollector() {
    return Collector.of(
            () -> new Tuple2<>(new HashMap<>(), new ArrayList<>()),
            (pair, entry) -> {
                if(entry.getValue() == null) {
                    pair._2.add(entry.getKey());
                } else {
                    pair._1.put(entry.getKey(), entry.getValue());
                }
            },
            (p1, p2) -> {
                p1._1.putAll(p2._1);
                p1._2.addAll(p2._2);
                return p1;
            });
}

with its usage:

Tuple2<Map<K, V>, List<K>> pair = 
    animalMap.entrySet().parallelStream().collect(customCollector());

You can tune it more if you want, for example by providing a predicate as parameter.

It depends on your OS, but if you are on Windows XP, you need to go to Systems Properties, then Advanced, then Environment Variables, and include the php binary path to the %PATH% variable.

Locate it by browsing your WAMP directory. It's called php.exe

First of all, cp33 means that it is to be used when you have Python 3.3 running on your system. So if you have Python 2.7 on your system, try installing the cp27 version.

Installing scipy-0.18.1-cp27-cp27m-win_amd64.whl, needs a Python 2.7 running and a 64-bit system.

If you are still getting an error saying "scipy-0.18.1-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform", then go for the win32 version. By this I mean install scipy-0.18.1-cp27-cp27m-win32.whl instead of the first one. This is because you might be running a 32-bit python on a 64-bit system. The last step successfully installed scipy for me.

Create a class like this:

public class Data
{
    public string Id {get; set;}
    public string Name {get; set;}
    public string First_Name {get; set;}
    public string Last_Name {get; set;}
    public string Username {get; set;}
    public string Gender {get; set;}
    public string Locale {get; set;}
}

(I'm not 100% sure, but if that doesn't work you'll need use [DataContract] and [DataMember] for DataContractJsonSerializer.)

Then create JSonSerializer:

private static readonly XmlObjectSerializer Serializer = new DataContractJsonSerializer(typeof(Data));

and deserialize object:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
using(var stream = new MemoryStream(byteArray))
{
    (Data)Serializer.ReadObject(stream);
}

Use this in your my.ini under

[mysqldump]
    user=root
    password=anything

I tweaked the accepted answer to perform the operation for multiple dataframes on different suffix parameters using reduce and i guess it can be extended to different on parameters as well.

from functools import reduce 

dfs_with_suffixes = [(df2,suffix2), (df3,suffix3), 
                     (df4,suffix4)]

merge_one = lambda x,y,sfx:pd.merge(x,y,on=['col1','col2'..], suffixes=sfx)

merged = reduce(lambda left,right:merge_one(left,*right), dfs_with_suffixes, df1)

The quick answer is to use a for() loop in place of your foreach() loops. Something like:

@for(var themeIndex = 0; themeIndex < Model.Theme.Count(); themeIndex++)
{
   @Html.LabelFor(model => model.Theme[themeIndex])

   @for(var productIndex=0; productIndex < Model.Theme[themeIndex].Products.Count(); productIndex++)
   {
      @Html.LabelFor(model=>model.Theme[themeIndex].Products[productIndex].name)
      @for(var orderIndex=0; orderIndex < Model.Theme[themeIndex].Products[productIndex].Orders; orderIndex++)
      {
          @Html.TextBoxFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].Quantity)
          @Html.TextAreaFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].Note)
          @Html.EditorFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].DateRequestedDeliveryFor)
      }
   }
}

But this glosses over why this fixes the problem.

There are three things that you have at least a cursory understanding before you can resolve this issue. I have to admit that I cargo-culted this for a long time when I started working with the framework. And it took me quite a while to really get what was going on.

Those three things are:

• How do the LabelFor and other ...For helpers work in MVC?
• What is an Expression Tree?
• How does the Model Binder work?

All three of these concepts link together to get an answer.

How do the LabelFor and other ...For helpers work in MVC?

So, you've used the HtmlHelper<T> extensions for LabelFor and TextBoxFor and others, and you probably noticed that when you invoke them, you pass them a lambda and it magically generates some html. But how?

So the first thing to notice is the signature for these helpers. Lets look at the simplest overload for TextBoxFor

public static MvcHtmlString TextBoxFor<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression
) 

First, this is an extension method for a strongly typed HtmlHelper, of type <TModel>. So, to simply state what happens behind the scenes, when razor renders this view it generates a class. Inside of this class is an instance of HtmlHelper<TModel> (as the property Html, which is why you can use @Html...), where TModel is the type defined in your @model statement. So in your case, when you are looking at this view TModel will always be of the type ViewModels.MyViewModels.Theme.

Now, the next argument is a bit tricky. So lets look at an invocation

@Html.TextBoxFor(model=>model.SomeProperty);

It looks like we have a little lambda, And if one were to guess the signature, one might think that the type for this argument would simply be a Func<TModel, TProperty>, where TModel is the type of the view model and TProperty is inferred as the type of the property.

But thats not quite right, if you look at the actual type of the argument its Expression<Func<TModel, TProperty>>.

So when you normally generate a lambda, the compiler takes the lambda and compiles it down into MSIL, just like any other function (which is why you can use delegates, method groups, and lambdas more or less interchangeably, because they are just code references.)

However, when the compiler sees that the type is an Expression<>, it doesn't immediately compile the lambda down to MSIL, instead it generates an Expression Tree!

What is an Expression Tree?

So, what the heck is an expression tree. Well, it's not complicated but its not a walk in the park either. To quote ms:

| Expression trees represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y.

Simply put, an expression tree is a representation of a function as a collection of "actions".

In the case of model=>model.SomeProperty, the expression tree would have a node in it that says: "Get 'Some Property' from a 'model'"

This expression tree can be compiled into a function that can be invoked, but as long as it's an expression tree, it's just a collection of nodes.

So what is that good for?

So Func<> or Action<>, once you have them, they are pretty much atomic. All you can really do is Invoke() them, aka tell them to do the work they are supposed to do.

Expression<Func<>> on the other hand, represents a collection of actions, which can be appended, manipulated, visited, or compiled and invoked.

So why are you telling me all this?

So with that understanding of what an Expression<> is, we can go back to Html.TextBoxFor. When it renders a textbox, it needs to generate a few things about the property that you are giving it. Things like attributes on the property for validation, and specifically in this case it needs to figure out what to name the <input> tag.

It does this by "walking" the expression tree and building a name. So for an expression like model=>model.SomeProperty, it walks the expression gathering the properties that you are asking for and builds <input name='SomeProperty'>.

For a more complicated example, like model=>model.Foo.Bar.Baz.FooBar, it might generate <input name="Foo.Bar.Baz.FooBar" value="[whatever FooBar is]" />

Make sense? It is not just the work that the Func<> does, but how it does its work is important here.

(Note other frameworks like LINQ to SQL do similar things by walking an expression tree and building a different grammar, that this case a SQL query)

How does the Model Binder work?

So once you get that, we have to briefly talk about the model binder. When the form gets posted, it's simply like a flat Dictionary<string, string>, we have lost the hierarchical structure our nested view model may have had. It's the model binder's job to take this key-value pair combo and attempt to rehydrate an object with some properties. How does it do this? You guessed it, by using the "key" or name of the input that got posted.

So if the form post looks like

Foo.Bar.Baz.FooBar = Hello

And you are posting to a model called SomeViewModel, then it does the reverse of what the helper did in the first place. It looks for a property called "Foo". Then it looks for a property called "Bar" off of "Foo", then it looks for "Baz"... and so on...

Finally it tries to parse the value into the type of "FooBar" and assign it to "FooBar".

PHEW!!!

And voila, you have your model. The instance the Model Binder just constructed gets handed into requested Action.

So your solution doesn't work because the Html.[Type]For() helpers need an expression. And you are just giving them a value. It has no idea what the context is for that value, and it doesn't know what to do with it.

Now some people suggested using partials to render. Now this in theory will work, but probably not the way that you expect. When you render a partial, you are changing the type of TModel, because you are in a different view context. This means that you can describe your property with a shorter expression. It also means when the helper generates the name for your expression, it will be shallow. It will only generate based on the expression it's given (not the entire context).

So lets say you had a partial that just rendered "Baz" (from our example before). Inside that partial you could just say:

@Html.TextBoxFor(model=>model.FooBar)

Rather than

@Html.TextBoxFor(model=>model.Foo.Bar.Baz.FooBar)

That means that it will generate an input tag like this:

<input name="FooBar" />

Which, if you are posting this form to an action that is expecting a large deeply nested ViewModel, then it will try to hydrate a property called FooBar off of TModel. Which at best isn't there, and at worst is something else entirely. If you were posting to a specific action that was accepting a Baz, rather than the root model, then this would work great! In fact, partials are a good way to change your view context, for example if you had a page with multiple forms that all post to different actions, then rendering a partial for each one would be a great idea.

Now once you get all of this, you can start to do really interesting things with Expression<>, by programatically extending them and doing other neat things with them. I won't get into any of that. But, hopefully, this will give you a better understanding of what is going on behind the scenes and why things are acting the way that they are.

This is the way it worked for me, because with other methods the form was sent empty:

<form name="yourform" id="yourform" method="POST" action="yourpage.html">
    <input type=hidden name="data" value="yourdata">
    <input type="submit" id="send" name="send" value="Send">
</form>
<script>            
    document.addEventListener("DOMContentLoaded", function(event) {
            document.createElement('form').submit.call(document.getElementById('yourform'));
            });         
</script>

In response to Jonathan's answer above, this only seems to work for certain delimiters. For example:

>>> a='Beautiful, is; better*than\nugly'
>>> import re
>>> re.split('; |, |\*|\n',a)
['Beautiful', 'is', 'better', 'than', 'ugly']

>>> b='1999-05-03 10:37:00'
>>> re.split('- :', b)
['1999-05-03 10:37:00']

By putting the delimiters in square brackets it seems to work more effectively.

>>> re.split('[- :]', b)
['1999', '05', '03', '10', '37', '00']

When you go to a stream url, you get offered a file. feed this file to a parser to extract the contents out of it. the file is (usually) plain text and contains the url to play.

A boolean cannot be null in java.

A Boolean, however, can be null.

If a boolean is not assigned a value (say a member of a class) then it will be false by default.

I have solved this cool custom progress bar by creating the custom view. I have overriden the onDraw() method to draw the circles, filled arc and text on the canvas.

following is the custom progress bar

import android.annotation.TargetApi;

import android.content.Context;

import android.graphics.Canvas;

In layout XML

<com.your.package.name.CustomProgressBar
            android:id="@+id/progress_bar"
            android:layout_width="70dp"
            android:layout_height="70dp"

in activity

CustomProgressBar progressBar = (CustomProgressBar)findViewById(R.id.progress_bar);

    progressBar.setMax(9);

    progressBar.setProgress(5);

Also you should know that you can force TLS v1.2 for Android 4.0 devices that don't have it enabled by default:

Put this code in onCreate() of your Application file:

try {
        ProviderInstaller.installIfNeeded(getApplicationContext());
        SSLContext sslContext;
        sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, null);
        sslContext.createSSLEngine();
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
            | NoSuchAlgorithmException | KeyManagementException e) {
        e.printStackTrace();
    }

To hide from the UI, use Format > Sheet > Hide

To hide programatically, use the Visible property of the Worksheet object. If you do it programatically, you can set the sheet as "very hidden", which means it cannot be unhidden through the UI.

ActiveWorkbook.Sheets("Name").Visible = xlSheetVeryHidden 
' or xlSheetHidden or xlSheetVisible

You can also set the Visible property through the properties pane for the worksheet in the VBA IDE (ALT+F11).

The Content-Security-Policy meta-tag allows you to reduce the risk of XSS attacks by allowing you to define where resources can be loaded from, preventing browsers from loading data from any other locations. This makes it harder for an attacker to inject malicious code into your site.

I banged my head against a brick wall trying to figure out why I was getting CSP errors one after another, and there didn't seem to be any concise, clear instructions on just how does it work. So here's my attempt at explaining some points of CSP briefly, mostly concentrating on the things I found hard to solve.

For brevity I won’t write the full tag in each sample. Instead I'll only show the content property, so a sample that says content="default-src 'self'" means this:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'">

1. How can I allow multiple sources?

You can simply list your sources after a directive as a space-separated list:

content="default-src 'self' https://example.com/js/"

Note that there are no quotes around parameters other than the special ones, like 'self'. Also, there's no colon (:) after the directive. Just the directive, then a space-separated list of parameters.

Everything below the specified parameters is implicitly allowed. That means that in the example above these would be valid sources:

https://example.com/js/file.js
https://example.com/js/subdir/anotherfile.js

These, however, would not be valid:

http://example.com/js/file.js
^^^^ wrong protocol

https://example.com/file.js
                   ^^ above the specified path

2. How can I use different directives? What do they each do?

The most common directives are:

• default-src the default policy for loading javascript, images, CSS, fonts, AJAX requests, etc
• script-src defines valid sources for javascript files
• style-src defines valid sources for css files
• img-src defines valid sources for images
• connect-src defines valid targets for to XMLHttpRequest (AJAX), WebSockets or EventSource. If a connection attempt is made to a host that's not allowed here, the browser will emulate a 400 error

There are others, but these are the ones you're most likely to need.

3. How can I use multiple directives?

You define all your directives inside one meta-tag by terminating them with a semicolon (;):

content="default-src 'self' https://example.com/js/; style-src 'self'"

4. How can I handle ports?

Everything but the default ports needs to be allowed explicitly by adding the port number or an asterisk after the allowed domain:

content="default-src 'self' https://ajax.googleapis.com http://example.com:123/free/stuff/"

The above would result in:

https://ajax.googleapis.com:123
                           ^^^^ Not ok, wrong port

https://ajax.googleapis.com - OK

http://example.com/free/stuff/file.js
                 ^^ Not ok, only the port 123 is allowed

http://example.com:123/free/stuff/file.js - OK

As I mentioned, you can also use an asterisk to explicitly allow all ports:

content="default-src example.com:*"

5. How can I handle different protocols?

By default, only standard protocols are allowed. For example to allow WebSockets ws:// you will have to allow it explicitly:

content="default-src 'self'; connect-src ws:; style-src 'self'"
                                         ^^^ web Sockets are now allowed on all domains and ports.

6. How can I allow the file protocol file://?

If you'll try to define it as such it won’t work. Instead, you'll allow it with the filesystem parameter:

content="default-src filesystem"

7. How can I use inline scripts and style definitions?

Unless explicitly allowed, you can't use inline style definitions, code inside <script> tags or in tag properties like onclick. You allow them like so:

content="script-src 'unsafe-inline'; style-src 'unsafe-inline'"

You'll also have to explicitly allow inline, base64 encoded images:

content="img-src data:"

8. How can I allow eval()?

I'm sure many people would say that you don't, since 'eval is evil' and the most likely cause for the impending end of the world. Those people would be wrong. Sure, you can definitely punch major holes into your site's security with eval, but it has perfectly valid use cases. You just have to be smart about using it. You allow it like so:

content="script-src 'unsafe-eval'"

9. What exactly does 'self' mean?

You might take 'self' to mean localhost, local filesystem, or anything on the same host. It doesn't mean any of those. It means sources that have the same scheme (protocol), same host, and same port as the file the content policy is defined in. Serving your site over HTTP? No https for you then, unless you define it explicitly.

I've used 'self' in most examples as it usually makes sense to include it, but it's by no means mandatory. Leave it out if you don't need it.

But hang on a minute! Can't I just use content="default-src *" and be done with it?

No. In addition to the obvious security vulnerabilities, this also won’t work as you'd expect. Even though some docs claim it allows anything, that's not true. It doesn't allow inlining or evals, so to really, really make your site extra vulnerable, you would use this:

content="default-src * 'unsafe-inline' 'unsafe-eval'"

... but I trust you won’t.

This question has been addressed, in a slightly different form, at length, here:

RESTful Authentication

But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:

Javascript Crypto is Hopeless

Matasano's article on this is famous, but the lessons contained therein are pretty important:

https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2011/august/javascript-cryptography-considered-harmful/

To summarize:

• A man-in-the-middle attack can trivially replace your crypto code with <script> function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
• A man-in-the-middle attack is trivial against a page that serves any resource over a non-SSL connection.
• Once you have SSL, you're using real crypto anyways.

And to add a corollary of my own:

• A successful XSS attack can result in an attacker executing code on your client's browser, even if you're using SSL - so even if you've got every hatch battened down, your browser crypto can still fail if your attacker finds a way to execute any javascript code on someone else's browser.

This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!

HTTP Basic Auth

First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.

This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.

The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.

This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!

The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.

HTTP Digest Auth

Is Digest authentication possible with jQuery?

A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.

Query Authentication with Additional Signature Parameters.

Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.

http://tools.ietf.org/html/rfc5849

Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?

JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.

Token

The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.

This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.

SSL Still

The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.

To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.

Token Expiry

It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX". Many of these policies are pretty good ideas.

Firesheeping

However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/

The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.

tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.

A Separate, More Secure Zone

The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?

Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.

Cookie (just means Token)

It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.

Session (still just means Token)

Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:

• Users start with an unauthenticated token.
• The backend maintains a 'state' object that is tied to a user's token.
• The token is provided in a cookie.
• The application environment abstracts the details away from you.

Aside from that, though, it's no different from Token Auth, really.

This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.

OAuth 2.0

OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."

The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."

Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.

There are two ways that OAuth 2.0 can help you:

• Providing Authentication/Information to Others
• Getting Authentication/Information from Others

But when it comes down to it, you're just... using tokens.

Back to your question

So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"

And the answer is: do whatever makes you happy.

The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.

I am 21 so SSL is yes

The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.

Normally you want to perform this check atomically with using the result, so stat() is useless. Instead, open() the file read-only first and use fstat(). If it's a directory, you can then use fdopendir() to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY extension to open which makes the call fail if the name is not a directory.

Your method with opendir() is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.

Create a DTO as CustomObject

Use below method to convert XML String to DTO using JAXB

private static CustomObject getCustomObject(final String ruleStr) {
    CustomObject customObject = null;
    try {
        JAXBContext jaxbContext = JAXBContext.newInstance(CustomObject.class);
        final StringReader reader = new StringReader(ruleStr);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        customObject = (CustomObject) jaxbUnmarshaller.unmarshal(reader);
    } catch (JAXBException e) {
        LOGGER.info("getCustomObject parse error: ", e);
    }
    return customObject;
}

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

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

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

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

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

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

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

You can calculate screen width. And you can scale bitmap.

 public static float getScreenWidth(Activity activity) {
        Display display = activity.getWindowManager().getDefaultDisplay();
        DisplayMetrics outMetrics = new DisplayMetrics();
        display.getMetrics(outMetrics);
        float pxWidth = outMetrics.widthPixels;
        return pxWidth;
    }

calculate screen width and scaled image height by screen width.

float screenWidth=getScreenWidth(act)
  float newHeight = screenWidth;
  if (bitmap.getWidth() != 0 && bitmap.getHeight() != 0) {
     newHeight = (screenWidth * bitmap.getHeight()) / bitmap.getWidth();
  }

After you can scale bitmap.

Bitmap scaledBitmap=Bitmap.createScaledBitmap(bitmap, (int) screenWidth, (int) newHeight, true);

You can change the color of the navigation icon programmatically like this:

mToolbar.setNavigationIcon(getColoredArrow()); 

private Drawable getColoredArrow() {
        Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
        Drawable wrapped = DrawableCompat.wrap(arrowDrawable);

        if (arrowDrawable != null && wrapped != null) {
            // This should avoid tinting all the arrows
            arrowDrawable.mutate();
                DrawableCompat.setTintList(wrapped, ColorStateList.valueOf(this.getResources().getColor(R.color.your_color)));
            }
        }

        return wrapped;
}

You could also use Hex Color Code,

Name    Hex Color Code  RGB Color Code
Red     #FF0000         rgb(255, 0, 0)
Maroon  #800000         rgb(128, 0, 0)
Yellow  #FFFF00         rgb(255, 255, 0)
Olive   #808000         rgb(128, 128, 0)

For example

import matplotlib.pyplot as plt

number_of_colors = 8

color = ["#"+''.join([random.choice('0123456789ABCDEF') for j in range(6)])

Lets try plotting them in a scatter plot

for i in range(number_of_colors):
    plt.scatter(random.randint(0, 10), random.randint(0,10), c=color[i], s=200)

plt.show()

1. Create new text file on desktop;

2. Enter desired commands in text file;

3. Rename extension of text file from ".txt" --> ".bat"

This is really just a syntax switch. OK, so we have this method call:

[NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];

In Swift, constructors skip the "blahWith…" part and just use the class name as a function and then go straight to the arguments, so [NSPredicate predicateWithFormat: …] would become NSPredicate(format: …). (For another example, [NSArray arrayWithObject: …] would become NSArray(object: …). This is a regular pattern in Swift.)

So now we just need to pass the arguments to the constructor. In Objective-C, NSString literals look like @"", but in Swift we just use quotation marks for strings. So that gives us:

let resultPredicate = NSPredicate(format: "name contains[c] %@", searchText)

And in fact that is exactly what we need here.

(Incidentally, you'll notice some of the other answers instead use a format string like "name contains[c] \(searchText)". That is not correct. That uses string interpolation, which is different from predicate formatting and will generally not work for this.)

Used Android Studio 0.8.9. The only way worked for me is using \n. Neither wrapping with CDATA nor <br> or <br /> worked.

You are trying to assign an array to ngClass, but the syntax for the array elements is wrong since you separate them with a || instead of a ,.

Try this:

<section [ngClass]="[menu1 ? 'class1' : '',  menu2 ? 'class1' : '', (something && (menu1 || menu2)) ? 'class2' : '']">

This other option should also work:

<section [ngClass.class1]="menu1 || menu2" [ngClass.class2] = "(menu1 || menu2) && something">    

This

var verificaHorario = $("#tbIntervalos").find("#" + horaInicial);

will find you the td that needs to be blocked.

Actually this will also do:

var verificaHorario = $("#" + horaInicial);

Testing for the size() of the wrapped set will answer your question regarding the existence of the id.

I don't have rep enough to comment so I'll format an answer, yet it is only a demonstration of the issue in question.

It seems, when element styles are defined in stylesheets they are not visible to getElementById("someElement").style

This code illustrates the issue... Code from below on jsFiddle.

In Test 2, on the first call, the items left value is undefined, and so, what should be a simple toggle gets messed up. For my use I will define my important style values inline, but it does seem to partially defeat the purpose of the stylesheet.

Here's the page code...

<html>
  <head>
    <style type="text/css">
      #test2a{
        position: absolute;
        left: 0px;
        width: 50px;
        height: 50px;
        background-color: green;
        border: 4px solid black;
      }
      #test2b{
        position: absolute;
        left: 55px;
        width: 50px;
        height: 50px;
        background-color: yellow;
        margin: 4px;
      }
    </style>
  </head>
  <body>

  <!-- test1 -->
    Swap left positions function with styles defined inline.
    <a href="javascript:test1();">Test 1</a><br>
    <div class="container">
      <div id="test1a" style="position: absolute;left: 0px;width: 50px; height: 50px;background-color: green;border: 4px solid black;"></div>
      <div id="test1b" style="position: absolute;left: 55px;width: 50px; height: 50px;background-color: yellow;margin: 4px;"></div>
    </div>
    <script type="text/javascript">
     function test1(){
       var a = document.getElementById("test1a");
       var b = document.getElementById("test1b");
       alert(a.style.left + " - " + b.style.left);
       a.style.left = (a.style.left == "0px")? "55px" : "0px";
       b.style.left = (b.style.left == "0px")? "55px" : "0px";
     }
    </script>
  <!-- end test 1 -->

  <!-- test2 -->
    <div id="moveDownThePage" style="position: relative;top: 70px;">
    Identical function with styles defined in stylesheet.
    <a href="javascript:test2();">Test 2</a><br>
    <div class="container">
      <div id="test2a"></div>
      <div id="test2b"></div>
    </div>
    </div>
    <script type="text/javascript">
     function test2(){
       var a = document.getElementById("test2a");
       var b = document.getElementById("test2b");
       alert(a.style.left + " - " + b.style.left);
       a.style.left = (a.style.left == "0px")? "55px" : "0px";
       b.style.left = (b.style.left == "0px")? "55px" : "0px";
     }
    </script>
  <!-- end test 2 -->

  </body>
</html>

I hope this helps to illuminate the issue.

Skip

Using generics (as in the above answers) is your best bet here. I've just double checked and:

test.put("test", arraylistone); 
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");

will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.

android:inputType="number" or android:inputType="phone". You can keep this. You will get the keyboard containing numbers. For further details on different types of keyboard, check this link.

I think it is possible only if you create your own soft keyboard. Or try this android:inputType="number|textVisiblePassword. But it still shows other characters. Besides you can keep android:digits="0123456789" to allow only numbers in your edittext. Or if you still want the same as in image, try combining two or more features with | separator and check your luck, but as per my knowledge you have to create your own keypad to get exactly like that..

Why not use list comprehension

l = [1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
n = 4
filler = 0
fills = len(l) % n
chunks = ((l + [filler] * fills)[x * n:x * n + n] for x in range(int((len(l) + n - 1)/n)))
print(chunks)

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

IF YOU CAN AVOID IT.. DON'T DO IT

Databases aren't really designed for this, you are effectively trying to create data (albeit a list of dates) within a query.

For anyone who has an application layer above the DB query the simplest solution is to fill in the blank data there.

You'll more than likely be looping through the query results anyway and can implement something like this:

loop_date = start_date

while (loop_date <= end_date){

  if(loop_date in db_data) {
    output db_data for loop_date
  }
  else {
    output default_data for loop_date
  }

  loop_date = loop_date + 1 day
}

The benefits of this are reduced data transmission; simpler, easier to debug queries; and no worry of over-flowing the calendar table.

Replace this

 <button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">

with

<button  value=" Send" class="btn btn-success" type="submit" id="submit">

so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:

1. delete node_modulesfolder
2. running npm install --global windows-build-tools
3. reinstalling node modules or node-sass with npm install

I suspect the condition you are looking for is DUP_VAL_ON_INDEX

EXCEPTION
    WHEN DUP_VAL_ON_INDEX THEN
        DBMS_OUTPUT.PUT_LINE('OH DEAR. I THINK IT IS TIME TO PANIC!')

In JDK 8 source can be found in /src.zip. Now in some intermediate releases this zip was missing but again it is available.

make sure that you select source as well from installation wizard.

Please try my profiler, called cRunWatch. It is just two files, so it is easy to integrate with your projects, and requires adding exactly one line to instrument a piece of code.

http://ravenspoint.wordpress.com/2010/06/16/timing/

Requires the Boost library.

try below code, it works for me in Mac10.10.2:

import subprocess

if __name__ == "__main__":
    result = subprocess.check_output('ifconfig en0 |grep -w inet', shell=True) # you may need to use eth0 instead of en0 here!!!
    print 'output = %s' % result.strip()
    # result = None
    ip = ''
    if result:
        strs = result.split('\n')
        for line in strs:
            # remove \t, space...
            line = line.strip()
            if line.startswith('inet '):
                a = line.find(' ')
                ipStart = a+1
                ipEnd = line.find(' ', ipStart)
                if a != -1 and ipEnd != -1:
                    ip = line[ipStart:ipEnd]
                    break
    print 'ip = %s' % ip

Below command will push all the branches(including the ones which you have never checked-out but present in your git repo, you can see them by git branch -a)

git push origin '*:*'

NOTE: This command comes handy when you are migrating version control service(i.e migrating from Gitlab to GitHub)

PowerShell has built-in XML and XPath functions. You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then .Node.'#text' to access node value.

[xml]$xml = Get-Content $serviceStatePath
$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml
$nodes | ForEach-Object {$_.Node.'#text'}

Or shorter

[xml]$xml = Get-Content $serviceStatePath
Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |
  % {$_.Node.'#text'}

In theory, yes, it's just a matter of plugging things in. Zipfile can give you a file-like object for a file in a zip archive, and image.load will accept a file-like object. So something like this should work:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
try:
    image = pygame.image.load(imgfile, 'img_01.png')
finally:
    imgfile.close()

here's non-paste methods

awk

awk 'BEGIN {OFS=" "}{
  getline line < "file2"
  print $0,line
} ' file1

Bash

exec 6<"file2"
while read -r line
do
    read -r f2line <&6
    echo "${line}${f2line}"
done <"file1"
exec 6<&-

I see you have a problem. Try building your app as Release and then check out your source codes build folder. It may be called Release-iphonesimulator. Inside here will be the app. Then go to (home folder)/Library/Application Support/iPhone Simulator (if you can't find it, try pressing Command - J and choosing arrange by name). Go to an OS that has apps in it in the iPhone sim, like 4.1. In that folder there should be an Applications folder. Open that, and there should be folders with random lettering. Pick any one, and replace it with the app you have. Make sure to delete anything in the little folders!

If it doesn't work, then I'm dumbfounded.

A quick and dirty hack to do this within the script is to direct the screen output to a file:

import sys 

stdoutOrigin=sys.stdout 
sys.stdout = open("log.txt", "w")

and then reverting back to outputting to screen at the end of your code:

sys.stdout.close()
sys.stdout=stdoutOrigin

This should work for a simple code, but for a complex code there are other more formal ways of doing it such as using Python logging.

str = "aaaaabbbb"
newstr = str[-4:]

See : http://codepad.org/S3zjnKoD

Short answer no :)

But you could just use the same CSS for the hover like so:

a:hover, .hoverclass {
    background:red;
}

Maybe if you explain why you need the class added, there may be a better solution?

In iOS 7 the status bar doesn't have a background, therefore if you put a black 20px-high view behind it you will achieve the same result as iOS 6.

Also you may want to read the iOS 7 UI Transition Guide for further information on the subject.

You can use reflection.

Type typeOfMyObject = myObject.GetType();
PropertyInfo[] properties =typeOfMyObject.GetProperties();

In XML add one line inside <Toolbar/>

<com.google.android.material.appbar.MaterialToolbar
app:menu="@menu/main_menu"/>

In java file, replace this:

 setSupportActionBar(toolbar);
        if (getSupportActionBar() != null) {
            getSupportActionBar().setTitle("Main Page");
        }

with this:

toolbar.setTitle("Main Page")

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

Use System.nanoTime to get the current time.

long startTime = System.nanoTime();
.....your program....
long endTime   = System.nanoTime();
long totalTime = endTime - startTime;
System.out.println(totalTime);

The above code prints the running time of the program in nanoseconds.

I simply declared as below in web.xml file and Its working for me :

 <welcome-file-list>
    <welcome-file>/WEB-INF/jsps/index.jsp</welcome-file>
</welcome-file-list>

And NO html/jsp pages present in public directory except static resources(css, js, images). Now I can access my index page with URL like : http://localhost:8080/app/ Its calling /WEB-INF/jsps/index.jsp page. When hosted live in production the final URL looks like https://eisdigital.com/

I presume you want to copy C:\OtherFolder\fileToCheck.bat to C:\MyFolder if the existing file in C:\MyFolder is either missing entirely, or if it is missing "stringToCheck".

FINDSTR sets ERRORLEVEL to 0 if the string is found, to 1 if it is not. It also sets errorlevel to 1 if the file is missing. It also prints out each line that matches. Since you are trying to use it as a condition, I presume you don't need or want to see any of the output. The 1st thing I would suggest is to redirect both the normal and error output to nul using >nul 2>&1.

Solution 1 (mostly the same as previous answers)

You can use IF ERRORRLEVEL N to check if the errorlevel is >= N. Or you can use IF NOT ERRORLEVEL N to check if errorlevel is < N. In your case you want the former.

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if errorlevel 1 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

Solution 2

You can test for a specific value of errorlevel by using %ERRORLEVEL%. You can probably check if the value is equal to 1, but it might be safer to check if the value is not equal to 0, since it is only set to 0 if the file exists and it contains the string.

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if not %errorlevel% == 0 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

or

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1
if %errorlevel% neq 0 xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

Solution 3

There is a very compact syntax to conditionally execute a command based on the success or failure of the previous command: cmd1 && cmd2 || cmd3 which means execute cmd2 if cmd1 was successful (errorlevel=0), else execute cmd3 if cmd1 failed (errorlevel<>0). You can use && alone, or || alone. All the commands need to be on the same line. If you need to conditionally execute multiple commands you can use multiple lines by adding parentheses

cmd1 && (
   cmd2
   cmd3
) || (
   cmd4
   cmd5
)

So for your case, all you need is

findstr /c:"stringToCheck" "c:\MyFolder\fileToCheck.bat" >nul 2>&1 || xcopy "C:\OtherFolder\fileToCheck.bat" "c:\MyFolder"

But beware - the || will respond to the return code of the last command executed. In my earlier pseudo code the || will obviously fire if cmd1 fails, but it will also fire if cmd1 succeeds but then cmd3 fails.

So if your success block ends with a command that may fail, then you should append a harmless command that is guaranteed to succeed. I like to use (CALL ), which is harmless, and always succeeds. It also is handy that it sets the ERRORLEVEL to 0. There is a corollary (CALL) that always fails and sets ERRORLEVEL to 1.

I had to do something very similar to find out why my iPhone was bleeding cellular network data, eating 80% of my 500Mb allowance in a couple of days.

Unfortunately I had to packet sniff whilst on 3G/4G and couldn't rely on being on wireless. So if you need an "industrial" solution then this is how you sniff all traffic (not just http) on any network.

Basic recipe:

1. Install VPN server
2. Run packet sniffer on VPN server
3. Connect iPhone to VPN server and perform operations
4. Download .pcap from VPN server and use your favourite .pcap analyser on it.

Detailed'ish instructions:

1. Get yourself a linux server, I used Fedora 20 64bit from Digirtal Ocean on a $5/month box
2. Configure OpenVPN on it. OpenVPN has comprehensive instructions
3. Ensure you configure the Routing all traffic through the VPN section
4. Be aware the instructions for (3) are all iptables which has been superseded, at time of writing, by firewall-cmd. This website explains the firewall-cmd to use
5. Check that you can connect your iPhone to the VPN. I did this by downloading the free OpenVPN software. I then set up a OpenVPN certificate. You can embed your ca, crt & key files by opening up and embedding the --- BEGIN CERTIFACTE --- ---- END CERTIFICATE --- in < ca > < /ca > < crt >< /crt>< key > < /key > blocks. Note that I had to do this in Mac with text editor, when I used notepad.exe on Win it didn't work. I then emailed this to my iphone and picked installed it.
6. Check the iPhone connects to VPN and routes it's traffic through (google what's my IP should return the VPN server IP when you run it on iPhone)
7. Now that you can connect go to your linux server & install wireshark (yum install wireshark)
8. This installs tshark, which is a command line packet sniffer. Run this in the background with screen tshark -i tun0 -x -w capture.pcap -F pcap (assuming vpn device is tun0)
9. Now when you want to capture traffic simply start the VPN on your machine
10. When complete switch off the VPN
11. Download the .pcap file from your server, and run analysis as you normally would. It's been decrypted on the server when it arrives so the traffic is viewable in plain text (obviously https still encrypted)

Note that the above implementation is not security focussed it's simply about getting a detailed packet capture of all of your iPhone's traffic on 3G/4G/Wireless networks

COUNT( posts.solved_post ) AS solved_post,
(SELECT users.username AS posted_by,
    users.id AS posted_by_id
    FROM users
    WHERE users.id = posts.posted_by)

Well, you can’t get multiple columns from one subquery like that. Luckily, the second column is already posts.posted_by! So:

SELECT
topics.id,
topics.name,
topics.post_count,
topics.view_count,
posts.posted_by
COUNT( posts.solved_post ) AS solved_post,
(SELECT users.username AS posted_by_username
    FROM users
    WHERE users.id = posts.posted_by)
...

Here's the solution I plan to go with. Not only does this work with non-sequential integers, but it should work with any other data type you may want to use as the underlying id for your enum values.

public Enum MyEnum {
    THIS(5),
    THAT(16),
    THE_OTHER(35);

    private int id; // Could be other data type besides int
    private MyEnum(int id) {
        this.id = id;
    }

    public int getId() {
        return this.id;
    }

    public static Map<Integer, MyEnum> buildMap() {
        Map<Integer, MyEnum> map = new HashMap<Integer, MyEnum>();
        MyEnum[] values = MyEnum.values();
        for (MyEnum value : values) {
            map.put(value.getId(), value);
        }

        return map;
    }
}

I only need to convert id's to enums at specific times (when loading data from a file), so there's no reason for me to keep the Map in memory at all times. If you do need the map to be accessible at all times, you can always cache it as a static member of your Enum class.

StringBuilder and StringBuffer are almost the same. The difference is that StringBuffer is synchronized and StringBuilder is not. Although, StringBuilder is faster than StringBuffer, the difference in performance is very little. StringBuilder is a SUN's replacement of StringBuffer. It just avoids synchronization from all the public methods. Rather than that, their functionality is the same.

Example of good usage:

If your text is going to change and is used by multiple threads, then it is better to use StringBuffer. If your text is going to change but is used by a single thread, then use StringBuilder.

This might be an old thread, but I'd like to mention Appcelerator Titanium, which allows anyone versed in HTML5/JavaScript/CSS to develop iOS applications.

Use GREATEST()

E.g.:

SELECT GREATEST(2,1);

Note: Whenever if any single value contains null at that time this function always returns null (Thanks to user @sanghavi7)

Providing the implementation details for the steps proposed by @CodesInChaos:

1) Check if there is a Byte Order Mark

2) Check if the file is valid UTF8

3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)

Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8. https://stackoverflow.com/a/4522251/867248 explains the tactic in more details.

using System; using System.IO; using System.Text;

// Using encoding from BOM or UTF8 if no BOM found,
// check if the file is valid, by reading all lines
// If decoding fails, use the local "ANSI" codepage

public string DetectFileEncoding(Stream fileStream)
{
    var Utf8EncodingVerifier = Encoding.GetEncoding("utf-8", new EncoderExceptionFallback(), new DecoderExceptionFallback());
    using (var reader = new StreamReader(fileStream, Utf8EncodingVerifier,
           detectEncodingFromByteOrderMarks: true, leaveOpen: true, bufferSize: 1024))
    {
        string detectedEncoding;
        try
        {
            while (!reader.EndOfStream)
            {
                var line = reader.ReadLine();
            }
            detectedEncoding = reader.CurrentEncoding.BodyName;
        }
        catch (Exception e)
        {
            // Failed to decode the file using the BOM/UT8. 
            // Assume it's local ANSI
            detectedEncoding = "ISO-8859-1";
        }
        // Rewind the stream
        fileStream.Seek(0, SeekOrigin.Begin);
        return detectedEncoding;
   }
}


[Test]
public void Test1()
{
    Stream fs = File.OpenRead(@".\TestData\TextFile_ansi.csv");
    var detectedEncoding = DetectFileEncoding(fs);

    using (var reader = new StreamReader(fs, Encoding.GetEncoding(detectedEncoding)))
    {
       // Consume your file
        var line = reader.ReadLine();
        ...

=IF(ISNA(INDEX(B:B,MATCH(C2,A:A,0))),"",INDEX(B:B,MATCH(C2,A:A,0)))

Your __init__.py should have a docstring.

Although all the functionality is implemented in modules and subpackages, your package docstring is the place to document where to start. For example, consider the python email package. The package documentation is an introduction describing the purpose, background, and how the various components within the package work together. If you automatically generate documentation from docstrings using sphinx or another package, the package docstring is exactly the right place to describe such an introduction.

Create a repository folder under your project. Let's take

${project.basedir}/src/main/resources/repo

Then, install your custom jar to this repo:

mvn install:install-file -Dfile=[FILE_PATH] \
-DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] \ 
-Dpackaging=jar -DlocalRepositoryPath=[REPO_DIR]

Lastly, add the following repo and dependency definitions to the projects pom.xml:

<repositories>
    <repository>
        <id>project-repo</id>
        <url>file://${project.basedir}/src/main/resources/repo</url>
    </repository>
</repositories>

<dependencies>    
    <dependency>
        <groupId>[GROUP]</groupId>
        <artifactId>[ARTIFACT]</artifactId>
        <version>[VERS]</version>
    </dependency>

@Steve Hobbs' answer is probably the best, but some of your other solutions could have worked. For example, @Html.Label(ViewBag.CurrentPath); will probably work with an explicit cast, like @Html.Label((string)ViewBag.CurrentPath);. Also, your reference to currentPath in @Html.Label(ViewData["CurrentPath"].ToString()); is capitalized, wherein your other code it is not, which is probably why you were getting null reference exceptions.

There's no defined order in a switch statement. You may look at the cases as something like a named label, like a goto label. Contrary to what people seem to think here, in the case of value 2 the default label is not jumped to. To illustrate with a classical example, here is Duff's device, which is the poster child of the extremes of switch/case in C.

send(to, from, count)
register short *to, *from;
register count;
{
  register n=(count+7)/8;
  switch(count%8){
    case 0: do{ *to = *from++;
    case 7:     *to = *from++;
    case 6:     *to = *from++;
    case 5:     *to = *from++;
    case 4:     *to = *from++;
    case 3:     *to = *from++;
    case 2:     *to = *from++;
    case 1:     *to = *from++;
            }while(--n>0);
  }
}

I think you might need to declare a view engine.

If you want to use a view/template engine:

app.set('view engine', 'ejs');

or

app.set('view engine', 'jade');

But to render plain-html, see this post: Render basic HTML view?.

You can download recent packages manually from these pages:

• https://packages.debian.org/fr/stretch/all/python3-pip/download
• https://packages.debian.org/fr/stretch/all/python-pip-whl/download

Then, install it by running dpkg:

dpkg -i *.deb

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms.

In the Java context, we first need to make a distinction between "copying a value" and "copying an object".

int a = 1;
int b = a;     // copying a value
int[] s = new int[]{42};
int[] t = s;   // copying a value (the object reference for the array above)

StringBuffer sb = new StringBuffer("Hi mom");
               // copying an object.
StringBuffer sb2 = new StringBuffer(sb);

In short, an assignment of a reference to a variable whose type is a reference type is "copying a value" where the value is the object reference. To copy an object, something needs to use new, either explicitly or under the hood.

Now for "shallow" versus "deep" copying of objects. Shallow copying generally means copying only one level of an object, while deep copying generally means copying more than one level. The problem is in deciding what we mean by a level. Consider this:

public class Example {
    public int foo;
    public int[] bar;
    public Example() { };
    public Example(int foo, int[] bar) { this.foo = foo; this.bar = bar; };
}

Example eg1 = new Example(1, new int[]{1, 2});
Example eg2 = ... 

The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g.

Example eg2 = new Example(eg1.foo, eg1.bar);

The normal interpretation of a "deep" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to a copy of the original array; e.g.

Example eg2 = new Example(eg1.foo, Arrays.copy(eg1.bar));

(People coming from a C / C++ background might say that a reference assignment produces a shallow copy. However, that's not what we normally mean by shallow copying in the Java context ...)

Two more questions / areas of uncertainty exist:

• How deep is deep? Does it stop at two levels? Three levels? Does it mean the whole graph of connected objects?

• What about encapsulated data types; e.g. a String? A String is actually not just one object. In fact, it is an "object" with some scalar fields, and a reference to an array of characters. However, the array of characters is completely hidden by the API. So, when we talk about copying a String, does it make sense to call it a "shallow" copy or a "deep" copy? Or should we just call it a copy?

Finally, clone. Clone is a method that exists on all classes (and arrays) that is generally thought to produce a copy of the target object. However:

• The specification of this method deliberately does not say whether this is a shallow or deep copy (assuming that is a meaningful distinction).

• In fact, the specification does not even specifically state that clone produces a new object.

Here's what the javadoc says:

"Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression x.clone() != x will be true, and that the expression x.clone().getClass() == x.getClass() will be true, but these are not absolute requirements. While it is typically the case that x.clone().equals(x) will be true, this is not an absolute requirement."

Note, that this is saying that at one extreme the clone might be the target object, and at the other extreme the clone might not equal the original. And this assumes that clone is even supported.

In short, clone potentially means something different for every Java class.

Some people argue (as @supercat does in comments) that the Java clone() method is broken. But I think the correct conclusion is that the concept of clone is broken in the context of OO. AFAIK, it is impossible to develop a unified model of cloning that is consistent and usable across all object types.

I was creating a form in which the user enters an email address used by another macro to email a specific cell group to the address entered. I patched together this simple code from several sites and my limited knowledge of VBA. This simply watches for one cell (In my case K22) to be updated and then kills any hyperlink in that cell.

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim KeyCells As Range

    ' The variable KeyCells contains the cells that will
    ' cause an alert when they are changed.
    Set KeyCells = Range("K22")

I'd suggest pulling from the remote branch as often as possible in order to minimise large merges and possible conflicts.

Having said that, I would go with the first option:

git add foo.js
git commit foo.js -m "commit"
git pull
git push

Commit your changes before pulling so that your commits are merged with the remote changes during the pull. This may result in conflicts which you can begin to deal with knowing that your code is already committed should anything go wrong and you have to abort the merge for whatever reason.

I'm sure someone will disagree with me though, I don't think there's any correct way to do this merge flow, only what works best for people.

Assuming a Windows installation, do please refer to this:

http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php

• Uninstall all Oracle components using the Oracle Universal Installer (OUI).
• Run regedit.exe and delete the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE key. This contains registry entires for all Oracle products.
• Delete any references to Oracle services left behind in the following part of the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ora* It should be pretty obvious which ones relate to Oracle.
• Reboot your machine.
• Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
• Delete the "C:\Program Files\Oracle" directory.
• Empty the contents of your "C:\temp" directory.
• Empty your recycle bin.

Calling additional attention to some great comments that were left here:

• Be careful when following anything listed here (above or below), as doing so may remove or damage any other Oracle-installed products.
• For 64-bit Windows (x64), you need also to delete the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE key from the registry.
• Clean-up by removing any related shortcuts that were installed to the Start Menu.
• Clean-up environment variables:
  • Consider removing %ORACLE_HOME%.
  • Remove any paths no longer needed from %PATH%.

This set of instructions happens to match an almost identical process that I had reverse-engineered myself over the years after a few messed-up Oracle installs, and has almost always met the need.

Note that even if the OUI is no longer available or doesn't work, simply following the remaining steps should still be sufficient.

Try an OUTER APPLY

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

Alternatively, you could GROUP BY the results

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

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

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

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

    List<Employee> employees = new ArrayList<>();
    employees.add(new Employee(1, "name1", addDays(new Date(), 1)));
    employees.add(new Employee(2, "name2", addDays(new Date(), 3)));
    employees.add(new Employee(3, "name3", addDays(new Date(), 6)));
    employees.add(new Employee(4, "name4", null));
    employees.add(new Employee(5, "name5", addDays(new Date(), 4)));
    employees.add(new Employee(6, "name6", addDays(new Date(), 5)));
    System.out.println(employees);
    Date maxDate = employees.stream().filter(emp -> emp.getJoiningDate() != null).map(Employee::getJoiningDate).max(Date::compareTo).get();
    System.out.println(format.format(maxDate));

}

public static Date addDays(Date date, int days) {
    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    cal.add(Calendar.DATE, days); // minus number would decrement the days

You would get below results :

Employee [empId=4, empName=name4, joiningDate=null],
Employee [empId=5, empName=name5, joiningDate=Sat Mar 24 13:33:09 EDT 2018],
Employee [empId=6, empName=name6, joiningDate=Sun Mar 25 13:33:09 EDT 2018]
]
2018-03-26
 maxDatedEmploye : Employee [empId=3, empName=name3, joiningDate=Mon Mar 26 13:33:09 EDT 2018]

 minDatedEmployee : Employee [empId=1, empName=name1, joiningDate=Wed Mar 21 13:33:09 EDT 2018]

Update : What if list itself is empty ?

        Date maxDate = employees.stream().filter(emp -> emp.getJoiningDate() != null).map(Employee::getJoiningDate).max(Date::compareTo).orElse(new Date());
    System.out.println(format.format(maxDate));
    Comparator<Employee> comparator = Comparator.comparing(Employee::getJoiningDate);
    Employee maxDatedEmploye = employees.stream().filter(emp -> emp.getJoiningDate() != null).max(comparator).orElse(null);
    System.out.println(" maxDatedEmploye : " + maxDatedEmploye);

Task.Run(() => Foo("bar"));

In windows first check under services if world wide web publishing services is running. If not start it.

If you cannot find it switch on IIS features of windows: In 7,8,10 it is under control panel , "turn windows features on or off". Internet Information Services World Wide web services and Internet information Services Hostable Core are required. Not sure if there is another way to get it going on windows, but this worked for me for all browsers. You might need to add localhost or http:/127.0.0.1 to the trusted websites also under IE settings.

Though the complete difference is more complicated, the only difference that concerns me is when the machine creates the function object. Which in the case of declarations is before any statement is executed but after a statement body is invoked (be that the global code body or a sub-function's), and in the case of expressions is when the statement it is in gets executed. Other than that for all intents and purposes browsers treat them the same.

To help you understand, take a look at this performance test which busted an assumption I had made of internally declared functions not needing to be re-created by the machine when the outer function is invoked. Kind of a shame too as I liked writing code that way.

Simplest solution:

$converted_res = $res ? 'true' : 'false';

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

As previously mentioned, the "correct" way to return a string from a function is with command substitution. In the event that the function also needs to output to console (as @Mani mentions above), create a temporary fd in the beginning of the function and redirect to console. Close the temporary fd before returning your string.

#!/bin/bash
# file:  func_return_test.sh
returnString() {
    exec 3>&1 >/dev/tty
    local s=$1
    s=${s:="some default string"}
    echo "writing directly to console"
    exec 3>&-     
    echo "$s"
}

my_string=$(returnString "$*")
echo "my_string:  [$my_string]"

executing script with no params produces...

# ./func_return_test.sh
writing directly to console
my_string:  [some default string]

hope this helps people

The only solution I have found is not to set the index to a previous frame and wait (then OpenCV stops reading frames, anyway), but to initialize the capture one more time. So, it looks like this:

cap = cv2.VideoCapture(camera_url)
while True:
    ret, frame = cap.read()

    if not ret:
        cap = cv.VideoCapture(camera_url)
        continue

    # do your processing here

And it works perfectly!

I use const on function parameters that are references (or pointers) which are only [in] data and will not be modified by the function. Meaning, when the purpose of using a reference is to avoid copying data and not to allow changing the passed parameter.

Putting const on the boolean b parameter in your example only puts a constraint on the implementation and doesn't contribute for the class's interface (although not changing parameters is usually advised).

The function signature for

void foo(int a);

and

void foo(const int a);

is the same, which explains your .c and .h

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

What about the shortcut CTRL+L?

It works for all shells e.g. Python, Bash, MySQL, MATLAB, etc.

You need to do this in a loop, there is no built-in operation to remove a number of indexes at once.

Your example is actually a contiguous sequence of indexes, so you can do this:

del my_list[2:6]

which removes the slice starting at 2 and ending just before 6.

It isn't clear from your question whether in general you need to remove an arbitrary collection of indexes, or if it will always be a contiguous sequence.

If you have an arbitrary collection of indexes, then:

indexes = [2, 3, 5]
for index in sorted(indexes, reverse=True):
    del my_list[index]

Note that you need to delete them in reverse order so that you don't throw off the subsequent indexes.

We create a resources.utf8 file that contains the resources in UTF-8 and have a rule to run the following:

native2ascii -encoding utf8 resources.utf8 resources.properties

We tried several things before arriving at an acceptable solution:

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....


root# grep -ibH "df" /usr/bin/xxd
Binary file /usr/bin/xxd matches
xxd -u /usr/bin/xxd | grep -H 'DF'
(standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....

Then found we could get usable results with

xxd -u /usr/bin/xxd > /tmp/xxd.hex ; grep -H 'DF' /tmp/xxd

Note that using a simple search target like 'DF' will incorrectly match characters that span across byte boundaries, i.e.

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....
--------------------^^

So we use an ORed regexp to search for ' DF' OR 'DF ' (the searchTarget preceded or followed by a space char).

The final result seems to be

xxd -u -ps -c 10000000000 DumpFile > DumpFile.hex
egrep ' DF|DF ' Dumpfile.hex

Add this function to your root App component and then run it from your constructor after adding your font using these instructions. https://medium.com/react-native-training/react-native-custom-fonts-ccc9aacf9e5e

import {Text, TextInput} from 'react-native'

SetDefaultFontFamily = () => {
    let components = [Text, TextInput]

    const customProps = {
        style: {
            fontFamily: "Rubik"
        }
    }

    for(let i = 0; i < components.length; i++) {
        const TextRender = components[i].prototype.render;
        const initialDefaultProps = components[i].prototype.constructor.defaultProps;
        components[i].prototype.constructor.defaultProps = {
            ...initialDefaultProps,
            ...customProps,
        }
        components[i].prototype.render = function render() {
            let oldProps = this.props;
            this.props = { ...this.props, style: [customProps.style, this.props.style] };
            try {
                return TextRender.apply(this, arguments);
            } finally {
                this.props = oldProps;
            }
        };
    }
}

I found the solution with this link : http://pixelsvsbytes.com/blog/2013/02/nice-web-fonts-for-every-browser/

Step by step method :

• send your font to a WebFontGenerator and get the zip
• find the TTF font on the Zip file
• then, on linux, do this command (or install by apt-get install ttfautohint):
  ttfautohint --strong-stem-width=g neosansstd-black.ttf neosansstd-black.changed.ttf
• then, one more, send the new TTF file (neosansstd-black.changed.ttf) on the WebFontGenerator
• you get a perfect Zip with all your webfonts !

I hope this will help.

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.

It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

You need to convert Array to string :

//arrayOfValues = [1, 2, 3];  
$.get('/controller/MyAction', { arrayOfValues: "1, 2, 3" }, function (data) {...

this works even in form of int, long or string

public ActionResult MyAction(int[] arrayOfValues )

int rows = 5;
int cols = 10;

int[] multD = new int[rows * cols];

for (int r = 0; r < rows; r++)
{
  for (int c = 0; c < cols; c++)
  {
     int index = r * cols + c;
     multD[index] = index * 2;
  }
}

Enjoy!

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

If you are having a lot activity like mine, in your application Or if you dont want to enter the code for each activity tag in manifest you can do this .

in your Application Base class you will get a lifecycle callback

so basically what happens in for each activity when creating the on create in Application Class get triggered here is the code ..

public class MyApplication extends Application{

@Override
    public void onCreate() {
        super.onCreate();  

  registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle bundle) {
                activity.setRequestedOrientation(
                        ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);


// for each activity this function is called and so it is set to portrait mode


            }

            @Override
            public void onActivityStarted(Activity activity) {

            }

            @Override
            public void onActivityResumed(Activity activity) {

            }

            @Override
            public void onActivityPaused(Activity activity) {

            }

            @Override
            public void onActivityStopped(Activity activity) {

            }

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {

            }

            @Override
            public void onActivityDestroyed(Activity activity) {

            }
        });
}

i hope this helps.

I had the same issue as described above the solutions given above are correct, the set up I have is as follows 1) Angularjs for the Client 2) Beego framework for GO server

Please following these points 1) CORS settings must be enabled only on GO server 2) Do NOT add any type of headers in angularJS except for this

.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }])

In you GO server add the CORS settings before the request starts to get processed so that the preflight request receives a 200 OK after which the the OPTIONS method will get converted to GET,POST,PUT or what ever is your request type.

Simple Fix that Worked for Me

Run df.reset_index(inplace=True) before grouping.

Thank you to this github comment for the solution.

Remove inplace if you want it to return the dataframe.

You can use the following URL as per the WhatsApp FAQ:

https://wa.me/PHONENUMBERHERE

Add the country code in front of the number and don't add any plus (+) sign or any dashes (-) or any other characters in the number. Only integrers/numeric values.

You can also predefine a text message to start with:

https://wa.me/PHONENUMBERHERE/?text=urlencodedtext

Yow can change the DropDownStyle in properties to DropDownList. This will not show the TextBox for filter.

_{(Screenshot provided by FUSION CHA0S.)}

You can use

String.PadLeft()
String.Format()

ProxyCommand nc -proxy xxx.com:8080 %h %p

remove -X connect and use -proxy instead.

Worked for me.

You use css to change the opacity. To cope with IE you'd need something like:

.opaque {
    opacity : 0.3;
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
    filter: alpha(opacity=30);
}

But the only problem with this is that it means anything inside the container will also be 0.3 opacity. Thus you'll have to change your HTML to have another container, not inside the transparent one, that holds your content.

Otherwise the png technique, would work. Except you'd need a fix for IE6, which in itself could cause problems.

itemgetter() is somewhat faster than lambda tup: tup[1], but the increase is relatively modest (around 10 to 25 percent).

(IPython session)

>>> from operator import itemgetter
>>> from numpy.random import randint
>>> values = randint(0, 9, 30000).reshape((10000,3))
>>> tpls = [tuple(values[i,:]) for i in range(len(values))]

>>> tpls[:5]    # display sample from list
[(1, 0, 0), 
 (8, 5, 5), 
 (5, 4, 0), 
 (5, 7, 7), 
 (4, 2, 1)]

>>> sorted(tpls[:5], key=itemgetter(1))    # example sort
[(1, 0, 0), 
 (4, 2, 1), 
 (5, 4, 0), 
 (8, 5, 5), 
 (5, 7, 7)]

>>> %timeit sorted(tpls, key=itemgetter(1))
100 loops, best of 3: 4.89 ms per loop

>>> %timeit sorted(tpls, key=lambda tup: tup[1])
100 loops, best of 3: 6.39 ms per loop

>>> %timeit sorted(tpls, key=(itemgetter(1,0)))
100 loops, best of 3: 16.1 ms per loop

>>> %timeit sorted(tpls, key=lambda tup: (tup[1], tup[0]))
100 loops, best of 3: 17.1 ms per loop

You can also use serializeArray function to do the same.

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()

Happy coding..

gcc and g++ are compiler-drivers of the GNU Compiler Collection (which was once upon a time just the GNU C Compiler).

Even though they automatically determine which backends (cc1 cc1plus ...) to call depending on the file-type, unless overridden with -x language, they have some differences.

The probably most important difference in their defaults is which libraries they link against automatically.

According to GCC's online documentation link options and how g++ is invoked, g++ is equivalent to gcc -xc++ -lstdc++ -shared-libgcc (the 1st is a compiler option, the 2nd two are linker options). This can be checked by running both with the -v option (it displays the backend toolchain commands being run).

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

Do as this:

Windows -> Show View -> Servers

Then in the Servers view, right-click and add new. It will show a pop up containing many server vendors. Under Apache select Tomcat v7.0 (Depending upon your downloaded server version). And in the run time configuration point it to the Tomcat folder you have downloaded.

You can try this article. It has the info you want !!

sudo apt-get install php-intl

then restart your server

Give a look at this link : http://zircote.com/swagger-php/installation.html

1. Download phar file https://github.com/zircote/swagger-php/blob/master/swagger.phar
2. Install Composer https://getcomposer.org/download/
3. Make composer.json
4. Clone swagger-php/library
5. Clone swagger-ui/library
6. Make Resource and Model php classes for the API
7. Execute the PHP file to generate the json
8. Give path of json in api-doc.json
9. Give path of api-doc.json in index.php inside swagger-ui dist folder

We can implement ajax request by using http service in AngularJs, which helps to read/load data from remote server.

$http service methods are listed below,

 $http.get()
 $http.post()
 $http.delete()
 $http.head()
 $http.jsonp()
 $http.patch()
 $http.put()

One of the Example:

    $http.get("sample.php")
        .success(function(response) {
            $scope.getting = response.data; // response.data is an array
    }).error(){

        // Error callback will trigger
    });

I think you will find that the following is more efficient:

IF OBJECT_ID('dbo.ProperCase') IS NOT NULL
    DROP FUNCTION dbo.ProperCase
GO
CREATE FUNCTION dbo.PROPERCASE (
    @str VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
    SET @str = ' ' + @str
    SET @str = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE( @str, ' a', ' A'), ' b', ' B'), ' c', ' C'), ' d', ' D'), ' e', ' E'), ' f', ' F'), ' g', ' G'), ' h', ' H'), ' i', ' I'), ' j', ' J'), ' k', ' K'), ' l', ' L'), ' m', ' M'), ' n', ' N'), ' o', ' O'), ' p', ' P'), ' q', ' Q'), ' r', ' R'), ' s', ' S'), ' t', ' T'), ' u', ' U'), ' v', ' V'), ' w', ' W'), ' x', ' X'), ' y', ' Y'), ' z', ' Z')
    RETURN RIGHT(@str, LEN(@str) - 1)
END
GO

The replace statement could be cut and pasted directly into a SQL query. It is ultra ugly, however by replacing @str with the column you are interested in, you will not pay a price for an implicit cursor like you will with the udfs thus posted. I find that even using my UDF it is much more efficient.

Oh and instead of generating the replace statement by hand use this:

-- Code Generator for expression
DECLARE @x  INT,
    @c  CHAR(1),
    @sql    VARCHAR(8000)
SET @x = 0
SET @sql = '@str' -- actual variable/column you want to replace
WHILE @x < 26
BEGIN
    SET @c = CHAR(ASCII('a') + @x)
    SET @sql = 'REPLACE(' + @sql + ', '' ' + @c+  ''', '' ' + UPPER(@c) + ''')'
    SET @x = @x + 1
END
PRINT @sql

Anyway it depends on the number of rows. I wish you could just do s/\b([a-z])/uc $1/, but oh well we work with the tools we have.

NOTE you would have to use this as you would have to use it as....SELECT dbo.ProperCase(LOWER(column)) since the column is in uppercase. It actually works pretty fast on my table of 5,000 entries (not even one second) even with the lower.

In response to the flurry of comments regarding internationalization I present the following implementation that handles every ascii character relying only on SQL Server's Implementation of upper and lower. Remember, the variables we are using here are VARCHAR which means that they can only hold ASCII values. In order to use further international alphabets, you have to use NVARCHAR. The logic would be similar but you would need to use UNICODE and NCHAR in place of ASCII AND CHAR and the replace statement would be much more huge....

-- Code Generator for expression
DECLARE @x  INT,
    @c  CHAR(1),
    @sql    VARCHAR(8000),
    @count  INT
SEt @x = 0
SET @count = 0
SET @sql = '@str' -- actual variable you want to replace
WHILE @x < 256
BEGIN
    SET @c = CHAR(@x)
    -- Only generate replacement expression for characters where upper and lowercase differ
    IF @x = ASCII(LOWER(@c)) AND @x != ASCII(UPPER(@c))
    BEGIN
        SET @sql = 'REPLACE(' + @sql + ', '' ' + @c+  ''', '' ' + UPPER(@c) + ''')'
        SET @count = @count + 1
    END
    SET @x = @x + 1
END
PRINT @sql
PRINT 'Total characters substituted: ' + CONVERT(VARCHAR(255), @count)

Basically the premise of the my method is trading pre-computing for efficiency. The full ASCII implementation is as follows:

IF OBJECT_ID('dbo.ProperCase') IS NOT NULL
    DROP FUNCTION dbo.ProperCase
GO
CREATE FUNCTION dbo.PROPERCASE (
    @str VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
    SET @str = ' ' + @str
SET @str =     REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(@str, ' a', ' A'), ' b', ' B'), ' c', ' C'), ' d', ' D'), ' e', ' E'), ' f', ' F'), ' g', ' G'), ' h', ' H'), ' i', ' I'), ' j', ' J'), ' k', ' K'), ' l', ' L'), ' m', ' M'), ' n', ' N'), ' o', ' O'), ' p', ' P'), ' q', ' Q'), ' r', ' R'), ' s', ' S'), ' t', ' T'), ' u', ' U'), ' v', ' V'), ' w', ' W'), ' x', ' X'), ' y', ' Y'), ' z', ' Z'), ' š', ' Š'), ' œ', ' Œ'), ' ž', ' Ž'), ' à', ' À'), ' á', ' Á'), ' â', ' Â'), ' ã', ' Ã'), ' ä', ' Ä'), ' å', ' Å'), ' æ', ' Æ'), ' ç', ' Ç'), ' è', ' È'), ' é', ' É'), ' ê', ' Ê'), ' ë', ' Ë'), ' ì', ' Ì'), ' í', ' Í'), ' î', ' Î'), ' ï', ' Ï'), ' ð', ' Ð'), ' ñ', ' Ñ'), ' ò', ' Ò'), ' ó', ' Ó'), ' ô', ' Ô'), ' õ', ' Õ'), ' ö', ' Ö'), ' ø', ' Ø'), ' ù', ' Ù'), ' ú', ' Ú'), ' û', ' Û'), ' ü', ' Ü'), ' ý', ' Ý'), ' þ', ' Þ'), ' ÿ', ' Ÿ')
    RETURN RIGHT(@str, LEN(@str) - 1)
END
GO

What you are saying is in conflict with what it says in the MSDN library at this location:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer.aspx

I don't see any mention of the SP1 feature you mention.

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

$arr1 = array(
   "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
   "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
   "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
   "3" => array("fid" => 1, "tid" => 7, "name" => "Xi"),
   "4" => array("fid" => 2, "tid" => 9, "name" => "Xigua")
);

if you want to convert this array as following:

$arr2 = array(
   "0" => array(
          "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
          "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
          "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
          "3" => array("fid" => 1, "tid" => 7, "name" => "Xi")
    ),

    "1" => array(
          "0" =>array("fid" => 2, "tid" => 9, "name" => "Xigua")
     )
);

so, my answer will be like this:

$outer_array = array();
$unique_array = array();
foreach($arr1 as $key => $value)
{
    $inner_array = array();

    $fid_value = $value['fid'];
    if(!in_array($value['fid'], $unique_array))
    {
            array_push($unique_array, $fid_value);
            unset($value['fid']);
            array_push($inner_array, $value);
            $outer_array[$fid_value] = $inner_array;


    }else{
            unset($value['fid']);
            array_push($outer_array[$fid_value], $value);

    }
}
var_dump(array_values($outer_array));

hope this answer will help somebody sometime.

You can use @JsonFormat annotation with shape as STRING on your BigDecimal variables. Refer below:

 import com.fasterxml.jackson.annotation.JsonFormat;

  class YourObjectClass {

      @JsonFormat(shape=JsonFormat.Shape.STRING)
      private BigDecimal yourVariable;

 }

Add a WHERE clause

UPDATE dbo.TestStudents  
SET     LASTNAME =  CASE  
                        WHEN LASTNAME = 'AAA' THEN 'BBB' 
                        WHEN LASTNAME = 'CCC' THEN 'DDD' 
                        WHEN LASTNAME = 'EEE' THEN 'FFF' 
                        ELSE LASTNAME
                    END 
WHERE   LASTNAME IN ('AAA', 'CCC', 'EEE')

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

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

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

libs/* is a path to your dependency JARs

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

The jar and dependent jar should have execute permissions.

So here is a simple example of how to use classes: Suppose you are a finance institute. You want your customer's accounts to be managed by a computer. So you need to model those accounts. That is where classes come in. Working with classes is called object oriented programming. With classes you model real world objects in your computer. So, what do we need to model a simple bank account? We need a variable that saves the balance and one that saves the customers name. Additionally, some methods to in- and decrease the balance. That could look like:

class bankaccount():
    def __init__(self, name, money):
        self.name = name
        self.money = money

    def earn_money(self, amount):
        self.money += amount

    def withdraw_money(self, amount):
        self.money -= amount

    def show_balance(self):
        print self.money

Now you have an abstract model of a simple account and its mechanism. The def __init__(self, name, money) is the classes' constructor. It builds up the object in memory. If you now want to open a new account you have to make an instance of your class. In order to do that, you have to call the constructor and pass the needed parameters. In Python a constructor is called by the classes's name:

spidermans_account = bankaccount("SpiderMan", 1000)

If Spiderman wants to buy M.J. a new ring he has to withdraw some money. He would call the withdraw method on his account:

spidermans_account.withdraw_money(100)

If he wants to see the balance he calls:

spidermans_account.show_balance()

The whole thing about classes is to model objects, their attributes and mechanisms. To create an object, instantiate it like in the example. Values are passed to classes with getter and setter methods like `earn_money()´. Those methods access your objects variables. If you want your class to store another object you have to define a variable for that object in the constructor.

You can leverage Apache Commons StringUtils.isEmpty(str), which checks for empty strings and handles null gracefully.

Example:

System.out.println(StringUtils.isEmpty("")); // true
System.out.println(StringUtils.isEmpty(null)); // true

Google Guava also provides a similar, probably easier-to-read method: Strings.isNullOrEmpty(str).

Example:

System.out.println(Strings.isNullOrEmpty("")); // true
System.out.println(Strings.isNullOrEmpty(null)); // true

Only want to clone the structure of table:

CREATE TABLE foo SELECT * FROM bar WHERE 1 = 2;

Also wants to copy the data:

CREATE TABLE foo as SELECT * FROM bar;

In My Visual Studio 2015, I ensured that the offending Visual Studio Project's Reference Paths List is empty:

I like google gson library.
When you don't know structure of json. You can use

JsonElement root = new JsonParser().parse(jsonString);

and then you can work with json. e.g. how to get "value1" from your gson:

String value1 = root.getAsJsonObject().get("data").getAsJsonObject().get("field1").getAsString();

dplyr

packages is always a saver in case of data wrangling. To add the desired division as a third variable I would use mutate()

d <- mutate(d, new = min / count2.freq)

Easy solution for .Net Core WinForms / WPF / .Net Standard Class Library projects

step 1: Install System.Configuration.ConfigurationManager by Nuget Manager

step 2: Add a new App.Config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Bodrum" value="Yalikavak" />    
  </appSettings>
</configuration>

step3: Get the value

string value = ConfigurationManager.AppSettings.Get("Bodrum");
// value is Yalikavak

If you are calling it from a Class Library then add the App.Config file on your Main Project.

I recently ran into this issue and none of the solutions proposed fixed it. The issue turned out to be an excessive use of datasets stored in the session. There was a flaw in the code that results in the session size to increase 10x.

There is an article on the msdn blog that also talks about this. http://blogs.msdn.com/b/johan/archive/2006/11/20/sessionstate-performance.aspx

I used a function to write custom trace messages to measure the size of the session data on the live site.

UPDATE 2016-03-02: As of Docker 1.9.0, Docker has named volumes which replace data-only containers. The answer below, as well as my linked blog post, still has value in the sense of how to think about data inside docker but consider using named volumes to implement the pattern described below rather than data containers.

I believe the canonical way to solve this is by using data-only containers. With this approach, all access to the volume data is via containers that use -volumes-from the data container, so the host uid/gid doesn't matter.

For example, one use case given in the documentation is backing up a data volume. To do this another container is used to do the backup via tar, and it too uses -volumes-from in order to mount the volume. So I think the key point to grok is: rather than thinking about how to get access to the data on the host with the proper permissions, think about how to do whatever you need -- backups, browsing, etc. -- via another container. The containers themselves need to use consistent uid/gids, but they don't need to map to anything on the host, thereby remaining portable.

This is relatively new for me as well but if you have a particular use case feel free to comment and I'll try to expand on the answer.

UPDATE: For the given use case in the comments, you might have an image some/graphite to run graphite, and an image some/graphitedata as the data container. So, ignoring ports and such, the Dockerfile of image some/graphitedata is something like:

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
RUN mkdir -p /data/graphite \
  && chown -R graphite:graphite /data/graphite
VOLUME /data/graphite
USER graphite
CMD ["echo", "Data container for graphite"]

Build and create the data container:

docker build -t some/graphitedata Dockerfile
docker run --name graphitedata some/graphitedata

The some/graphite Dockerfile should also get the same uid/gids, therefore it might look something like this:

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
# ... graphite installation ...
VOLUME /data/graphite
USER graphite
CMD ["/bin/graphite"]

And it would be run as follows:

docker run --volumes-from=graphitedata some/graphite

Ok, now that gives us our graphite container and associated data-only container with the correct user/group (note you could re-use the some/graphite container for the data container as well, overriding the entrypoing/cmd when running it, but having them as separate images IMO is clearer).

Now, lets say you want to edit something in the data folder. So rather than bind mounting the volume to the host and editing it there, create a new container to do that job. Lets call it some/graphitetools. Lets also create the appropriate user/group, just like the some/graphite image.

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
VOLUME /data/graphite
USER graphite
CMD ["/bin/bash"]

You could make this DRY by inheriting from some/graphite or some/graphitedata in the Dockerfile, or instead of creating a new image just re-use one of the existing ones (overriding entrypoint/cmd as necessary).

Now, you simply run:

docker run -ti --rm --volumes-from=graphitedata some/graphitetools

and then vi /data/graphite/whatever.txt. This works perfectly because all the containers have the same graphite user with matching uid/gid.

Since you never mount /data/graphite from the host, you don't care how the host uid/gid maps to the uid/gid defined inside the graphite and graphitetools containers. Those containers can now be deployed to any host, and they will continue to work perfectly.

The neat thing about this is that graphitetools could have all sorts of useful utilities and scripts, that you can now also deploy in a portable manner.

UPDATE 2: After writing this answer, I decided to write a more complete blog post about this approach. I hope it helps.

UPDATE 3: I corrected this answer and added more specifics. It previously contained some incorrect assumptions about ownership and perms -- the ownership is usually assigned at volume creation time i.e. in the data container, because that is when the volume is created. See this blog. This is not a requirement though -- you can just use the data container as a "reference/handle" and set the ownership/perms in another container via chown in an entrypoint, which ends with gosu to run the command as the correct user. If anyone is interested in this approach, please comment and I can provide links to a sample using this approach.

Go to app/config/app.php

and set 'debug' => true,

Step 1: Open plugin manager in notepad++

Plugins -> Plugin Manager -> Show Plugin Manager.

Step 2:install XML Tool plugin

Search "XML TOOLS" from the "Available" option then click in install.

Now you can use shortcut key CTRL+ALT+SHIFT+B to indent the code.

The following code works fine with me:

brew install zbar
pip install pyqrcode
pip install pyzbar

For QR code image creation:

import pyqrcode
qr = pyqrcode.create("test1")
qr.png("test1.png", scale=6)

For QR code decoding:

from PIL import Image
from pyzbar.pyzbar import decode
data = decode(Image.open('test1.png'))
print(data)

that prints the result:

[Decoded(data=b'test1', type='QRCODE', rect=Rect(left=24, top=24, width=126, height=126), polygon=[Point(x=24, y=24), Point(x=24, y=150), Point(x=150, y=150), Point(x=150, y=24)])]

If your project is not a Gradle project,

And you got this "local path doesn't exist" error after updating Android Studio to 0.9.2+ version

You should open the .iml file of the project and remove this:

<facet type="android-gradle" name="Android-Gradle">
  <configuration>
    <option name="GRADLE_PROJECT_PATH" />
  </configuration>
</facet>

It solved the problem for me.

Use Kotlin Coroutines to Handle Threading

The reason the code is crashing is because the Bitmap is attempting to be created on the Main Thread which is not allowed since it may cause Android Not Responding (ANR) errors.

Concepts Used

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

Implementation

Code

1. Create Bitmap in a different thread then the Main Thread.

In this sample using Kotlin Coroutines the function is being executed in the Dispatchers.IO thread which is meant for CPU based operations. The function is prefixed with suspend which is a Coroutine syntax.

Bonus - After the Bitmap is created it is also compressed into an ByteArray so it can be passed via an Intent later outlined in this full sample.

Repository.kt

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

ViewModel.kt

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

Bonus - Convert ByteArray back to Bitmap.

Utils.kt

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

geolocator.js can do that. (I'm the author).

Getting City Name (Limited Address)

geolocator.locateByIP(options, function (err, location) {
    console.log(location.address.city);
});

Getting Full Address Information

Example below will first try HTML5 Geolocation API to obtain the exact coordinates. If fails or rejected, it will fallback to Geo-IP look-up. Once it gets the coordinates, it will reverse-geocode the coordinates into an address.

var options = {
    enableHighAccuracy: true,
    fallbackToIP: true, // fallback to IP if Geolocation fails or rejected
    addressLookup: true
};
geolocator.locate(options, function (err, location) {
    console.log(location.address.city);
});

This uses Google APIs internally (for address lookup). So before this call, you should configure geolocator with your Google API key.

geolocator.config({
    language: "en",
    google: {
        version: "3",
        key: "YOUR-GOOGLE-API-KEY"
    }
});

Geolocator supports geo-location (via HTML5 or IP lookups), geocoding, address look-ups (reverse geocoding), distance & durations, timezone information and a lot more features...

Just create your own template for the type in Views/Shared/EditorTemplates/MyTypeEditor.vbhtml

@ModelType MyType

@ModelType MyType
@Code
    Dim name As String = ViewData("ControlId")
    If String.IsNullOrEmpty(name) Then
        name = "MyTypeEditor"
    End If
End Code

' Mark-up for MyType Editor
@Html.TextBox(name, Model, New With {.style = "width:65px;background-color:yellow"})

Invoke editor from your view with the model property:

@Html.EditorFor(Function(m) m.MyTypeProperty, "MyTypeEditor", New {.ControlId = "uniqueId"})

Pardon the VB syntax. That's just how we roll.

I use WinSplit Revolution for the keyboard arrangement capability and I use bblean as a replacement for Explorer. It has multiple workspace capabilities built right in and it allows you to customize it exactly how you want it to look.

Be careful with the syntax! Great Turtle used them interchangeably, but:

error_page 404 = /404.html;

Will return the 404.html page with a status code of 200 (because = has relayed that to this page)

error_page 404 /404.html;

Will return the 404.html page with a (the original) 404 error code.

I use this function in my python programs. The input for the function is as example:
value = time.time()

def stopWatch(value):
    '''From seconds to Days;Hours:Minutes;Seconds'''

    valueD = (((value/365)/24)/60)
    Days = int (valueD)

    valueH = (valueD-Days)*365
    Hours = int(valueH)

    valueM = (valueH - Hours)*24
    Minutes = int(valueM)

    valueS = (valueM - Minutes)*60
    Seconds = int(valueS)


    print Days,";",Hours,":",Minutes,";",Seconds




start = time.time() # What in other posts is described is

***your code HERE***

end = time.time()         
stopWatch(end-start) #Use then my code

In case you need to apply a dynamic delay with the lodash's debounce function:

props: {
  delay: String
},

data: () => ({
  search: null
}),

created () {
     this.valueChanged = debounce(function (event) {
      // Here you have access to `this`
      this.makeAPIrequest(event.target.value)
    }.bind(this), this.delay)

},

methods: {
  makeAPIrequest (newVal) {
    // ...
  }
}

And the template:

<template>
  //...

   <input type="text" v-model="search" @input="valueChanged" />

  //...
</template>

NOTE: in the example above I made an example of search input which can call the API with a custom delay which is provided in props

It works in Chrome 19.0.1084.41 beta!

So at some point in the future, keyframes could really be... frames!

If you use ng-model, you don't want to also use ng-checked. Instead just initialize the model variable to true. Normally you would do this in a controller that is managing your page (add one). In your fiddle I just did the initialization in an ng-init attribute for demonstration purposes.

http://jsfiddle.net/UTULc/

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-init="checked=true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>

To resolve this problem you first need to check the SSL certificates of the host your are connecting to. For example using ssllabs or other ssl tools. In my case the intermediate certificate was wrong.

If the certificate is ok, make sure the openSSL on your server is up to date. Run openssl -v to check your version. Maybe your version is to old to work with the certificate.

In very rare cases you might want to disable ssl security features like verify_peer, verify_peer_name or allow_self_signed. Please be very careful with this and never use this in production. This is only an option for temporary testing.

If you are looking for a built-in Java two-element tuple, try AbstractMap.SimpleEntry.

I don't know what things were like in the alpha, but I'm using beta 12 right now and this works fine. If you have an array of objects, create a select like this:

<select [(ngModel)]="simpleValue"> // value is a string or number
    <option *ngFor="let obj of objArray" [value]="obj.value">{{obj.name}}</option>
</select>

If you want to match on the actual object, I'd do it like this:

<select [(ngModel)]="objValue"> // value is an object
    <option *ngFor="let obj of objArray" [ngValue]="obj">{{obj.name}}</option>
</select>

I want to add to Michael Berkowski's answer that this can also happen if the array's order is reversed, in which case it's a bit trickier to observe the issue, because in the json object, the order will be ordered ascending.

For example:

[
    3 => 'a',
    2 => 'b',
    1 => 'c',
    0 => 'd'
]

Will return:

{
    0: 'd',
    1: 'c',
    2: 'b',
    3: 'a'
}

So the solution in this case, is to use array_reverse before encoding it to json

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

Here is a working Swift 3 solution from one of my apps.
