I think...

Search partial value:

SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])*key_word([^"])*"';

Search exact word:

SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';

They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.

-- Initialize a variable, give it a data type and an initial value

declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed

-- Increse that the vaue by 1

set @myvar = 123456.7

--Retrieve that value

select @myvar as myVariable

In Kotlin you can use extensions as below:

fun String.toDoubleEx() : Double {
   val decimalSymbol = DecimalFormatSymbols.getInstance().decimalSeparator
  return if (decimalSymbol == ',') {
      this.replace(decimalSymbol, '.').toDouble()
  } else {
      this.toDouble()
  }
}

and you can use it everywhere in your code like this:

val myNumber1 = "5,2"
val myNumber2 = "6.7"

val myNum1 = myNumber1.toDoubleEx()
val myNum2 = myNumber2.toDoubleEx()

It is easy and universal!

First of all, you can't pass to alert second argument, use concatenation instead

alert("Input is " + inputValue);

Example

However in order to get values from input better to use states like this

var MyComponent = React.createClass({_x000D_
  getInitialState: function () {_x000D_
    return { input: '' };_x000D_
  },_x000D_
_x000D_
  handleChange: function(e) {_x000D_
    this.setState({ input: e.target.value });_x000D_
  },_x000D_
_x000D_
  handleClick: function() {_x000D_
    console.log(this.state.input);_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <input type="text" onChange={ this.handleChange } />_x000D_
        <input_x000D_
          type="button"_x000D_
          value="Alert the text input"_x000D_
          onClick={this.handleClick}_x000D_
        />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
ReactDOM.render(_x000D_
  <MyComponent />,_x000D_
  document.getElementById('container')_x000D_

From C++ FAQ Lite -

Use references when you can, and pointers when you have to.

References are usually preferred over pointers whenever you don't need "reseating". This usually means that references are most useful in a class's public interface. References typically appear on the skin of an object, and pointers on the inside.

The exception to the above is where a function's parameter or return value needs a "sentinel" reference — a reference that does not refer to an object. This is usually best done by returning/taking a pointer, and giving the NULL pointer this special significance (references must always alias objects, not a dereferenced NULL pointer).

Note: Old line C programmers sometimes don't like references since they provide reference semantics that isn't explicit in the caller's code. After some C++ experience, however, one quickly realizes this is a form of information hiding, which is an asset rather than a liability. E.g., programmers should write code in the language of the problem rather than the language of the machine.

Definitely, there is no solution with pure HTML to submit a form with a link (a) tag. The standard HTML accepts only buttons or images. As some other collaborators have said, one can simulate the appearance of a link using a button, but I guess that's not the purpose of the question.

IMHO, I believe that the proposed and accepted solution does not work.

I have tested it on a form and the browser didn't find the reference to the form.

So it is possible to solve it using a single line of JavaScript, using this object, which references the element being clicked, which is a child node of the form, that needs to be submitted. So this.parentNode is the form node. After it's just calling submit() method in that form. It's no necessary research from whole document to find the right form.

<form action="http://www.greatsolutions.com.br/indexint.htm"                   
   method="get">
    <h3> Enter your name</h3>
    First Name <input type="text"  name="fname"  size="30"><br>
    Last Name <input type="text" name="lname" size="30"><br>
    <a href="#" onclick="this.parentNode.submit();"> Submit here</a>
</form>

Suppose that I enter with my own name:

I've used get in form method attribute because it's possible to see the right parameters in the URL at loaded page after submit.

http://www.greatsolutions.com.br/indexint.htm?fname=Paulo&lname=Buchsbaum

This solution obviously applies to any tag that accepts the onclick event or some similar event.

this is a excellent choice to recover the context together with event variable (available in all major browsers and IE9 onwards) that can be used directly or passed as an argument to a function.

In this case, replace the line with a tag by the line below, using the property target, that indicates the element that has started the event.

<a href="#" onclick="event.target.parentNode.submit();"> Submit here</a>

$record = '123';

$this->db->distinct();

$this->db->select('accessid');

$this->db->where('record', $record); 

$query = $this->db->get('accesslog');

then

$query->num_rows();

should go a long way towards it.

Since Java 8, there are some standard options to do this in JDK:

Collection<E> in = ...
Object[] mapped = in.stream().map(e -> doMap(e)).toArray();
// or
List<E> mapped = in.stream().map(e -> doMap(e)).collect(Collectors.toList());

See java.util.Collection.stream() and java.util.stream.Collectors.toList().

This is building off the work Daniel Little did for this question, but taking into account daylight savings time (works for dates 01-01 1902 and greater due to int limit on dateadd function):

We first need to create a table that will store the date ranges for daylight savings time (source: History of time in the United States):

CREATE TABLE [dbo].[CFG_DAY_LIGHT_SAVINGS_TIME](
  [BEGIN_DATE] [datetime] NULL,
  [END_DATE] [datetime] NULL,
  [YEAR_DATE] [smallint] NULL
) ON [PRIMARY]

A Subquery in the Select clause, as in your case, is also known as a Scalar Subquery, which means that it's a form of expression. Meaning that it can only return one value.

I'm afraid you can't return multiple columns from a single Scalar Subquery, no.

Here's more about Oracle Scalar Subqueries:

http://docs.oracle.com/cd/B19306_01/server.102/b14200/expressions010.htm#i1033549

Well. This question is old, i was here today...but in the end i used an way simpler approach.

1. Boolean - if something is being done, true. When it ends, false.
2. Before processing , add it to a HashSet. This way i won't be repeating elements.
3. Every 30 minutes the elapsed event of an timer runs, and if there's no job being executed it will clear the list (just hashset = new hashset).

I hope i contributed with something =)

in bootstrap 3.3.7 (and 4.0 presumably), this works:

instead of:

<nav class="navbar navbar-inverse navbar-fixed-top">

use:

<nav class="navbar bg-transparent navbar-fixed-top">

no CSS required!

You can use the EXACT Function for exact string comparisons.

=IF(EXACT(A1, "ENG"), 1, 0)

After lot of struggle finally got it working. ( Perfectly tested)

The below example will also support the fact that color of already clicked button should not be changes

JQuery Code

var flag = 0; // Flag is to check if you are hovering on already clicked item

$("a").click(function() {
    $('a').removeClass("YourColorClass");
    $(this).addClass("YourColorClass");
    flag=1;
}); 

$("a").mouseover(function() {
    if ($(this).hasClass("YourColorClass")) {
        flag=1;
    }
    else{
        $(this).addClass("YourColorClass");
    };
});

$("a").mouseout(function() {
    if (flag == 0) {
        $(this).removeClass("YourColorClass");
    }
    else{
        flag = 0;
    }
});

The behaviour may be undefined, but that just means there isn't a "standard". All decent compilers offer #pragmas to control packing and alignment, but may have different defaults. The defaults will also change depending on the optimisation settings used.

Also, unions are not just for saving space. They can help modern compilers with type punning. If you reinterpret_cast<> everything the compiler can't make assumptions about what you are doing. It may have to throw away what it knows about your type and start again (forcing a write back to memory, which is very inefficient these days compared to CPU clock speed).

To add some clarification here, when you create your service, the service class uses the default 'wsdlLocation', which was inserted into it when the class was built from the wsdl. So if you have a service class called SomeService, and you create an instance like this:

SomeService someService = new SomeService();

If you look inside SomeService, you will see that the constructor looks like this:

public SomeService() {
        super(__getWsdlLocation(), SOMESERVICE_QNAME);
}

So if you want it to point to another URL, you just use the constructor that takes a URL argument (there are 6 constructors for setting qname and features as well). For example, if you have set up a local TCP/IP monitor that is listening on port 9999, and you want to redirect to that URL:

URL newWsdlLocation = new URL("http://theServerName:9999/somePath");
SomeService someService = new SomeService(newWsdlLocation);

and that will call this constructor inside the service:

public SomeService(URL wsdlLocation) {
    super(wsdlLocation, SOMESERVICE_QNAME);
}

Encapsulation is wrapping up of data and methods in a single unit and making the data accessible only through methods(getter/setter) to ensure safety of data.

Abstraction is hiding internal implementation details of how work is done.

Take and example of following stack class:

Class Stack
{
private top;
void push();
int pop();
}

Now encapsulation helps to safeguard internal data as top cannot be accessed directly outside.

And abstraction helps to do push or pop on stack without worrying about what are steps to push or pop

Here's how you can POST XML on Windows using curl command line on Windows. Better use batch/.cmd file for that:

curl -i -X POST -H "Content-Type: text/xml" -d             ^

Like what has been mentioned before, pandas object is most efficient when process the whole array at once. However for those who really need to loop through a pandas DataFrame to perform something, like me, I found at least three ways to do it. I have done a short test to see which one of the three is the least time consuming.

t = pd.DataFrame({'a': range(0, 10000), 'b': range(10000, 20000)})
B = []
C = []
A = time.time()
for i,r in t.iterrows():
    C.append((r['a'], r['b']))
B.append(time.time()-A)

C = []
A = time.time()
for ir in t.itertuples():
    C.append((ir[1], ir[2]))    
B.append(time.time()-A)

C = []
A = time.time()
for r in zip(t['a'], t['b']):
    C.append((r[0], r[1]))
B.append(time.time()-A)

print B

Result:

[0.5639059543609619, 0.017839908599853516, 0.005645036697387695]

This is probably not the best way to measure the time consumption but it's quick for me.

Here are some pros and cons IMHO:

• .iterrows(): return index and row items in separate variables, but significantly slower
• .itertuples(): faster than .iterrows(), but return index together with row items, ir[0] is the index
• zip: quickest, but no access to index of the row

For what it is worth, here is an updated benchmark with some other alternatives (perf with MacBookPro 2,4 GHz Intel Core i9 8 cores 32 Go 2667 MHz DDR4)

    A = time.time()
    for i,r in t.iterrows():
        C.append((r['a'], r['b']))
    B.append({"method": "iterrows", "time": time.time()-A})

    C = []
    A = time.time()
    for ir in t.itertuples():
        C.append((ir[1], ir[2]))
    B.append({"method": "itertuples", "time": time.time()-A})

    C = []
    A = time.time()
    for r in zip(t['a'], t['b']):
        C.append((r[0], r[1]))
    B.append({"method": "zip", "time": time.time()-A})

    C = []
    A = time.time()
    for r in zip(*t.to_dict("list").values()):
        C.append((r[0], r[1]))
    B.append({"method": "zip + to_dict('list')", "time": time.time()-A})

    C = []
    A = time.time()
    for r in t.to_dict("records"):
        C.append((r["a"], r["b"]))
    B.append({"method": "to_dict('records')", "time": time.time()-A})

    A = time.time()
    t.agg(tuple, axis=1).tolist()
    B.append({"method": "agg", "time": time.time()-A})

    A = time.time()
    t.apply(tuple, axis=1).tolist()
    B.append({"method": "apply", "time": time.time()-A})

print(f'Python {sys.version} on {sys.platform}')

That's it...

This actually depends on your external component. When you reference an external component in a .NET application it generates a GUID to identify that component. This error occurs when the external component referenced by one of your projects has the same name and but different version as another such component in another assembly.

This sometimes happens when you use "Browse" to find references and add the wrong version of the assembly, or you have a different version of the component in your code repository as the one you installed in the local machine.

Do try to find which projects have these conflicts, remove the components from the reference list, then add them again making sure that you're pointing to the same file.

you can unpack your tuples and get only the first element using a list comprehension:

l = [(1, u'abc'), (2, u'def')]
[f for f, *_ in l]

output:

[1, 2]

this will work no matter how many elements you have in a tuple:

l = [(1, u'abc'), (2, u'def', 2, 4, 5, 6, 7)]
[f for f, *_ in l]

output:

[1, 2]

The main function must be declared as a non-member function in the global namespace. This means that it cannot be a static or non-static member function of a class, nor can it be placed in a namespace (even the unnamed namespace).

The name main is not reserved in C++ except as a function in the global namespace. You are free to declare other entities named main, including among other things, classes, variables, enumerations, member functions, and non-member functions not in the global namespace.

You can declare a function named main as a member function or in a namespace, but such a function would not be the main function that designates where the program starts.

The main function cannot be declared as static or inline. It also cannot be overloaded; there can be only one function named main in the global namespace.

The main function cannot be used in your program: you are not allowed to call the main function from anywhere in your code, nor are you allowed to take its address.

The return type of main must be int. No other return type is allowed (this rule is in bold because it is very common to see incorrect programs that declare main with a return type of void; this is probably the most frequently violated rule concerning the main function).

There are two declarations of main that must be allowed:

int main()               // (1)
int main(int, char*[])   // (2)

In (1), there are no parameters.

In (2), there are two parameters and they are conventionally named argc and argv, respectively. argv is a pointer to an array of C strings representing the arguments to the program. argc is the number of arguments in the argv array.

Usually, argv[0] contains the name of the program, but this is not always the case. argv[argc] is guaranteed to be a null pointer.

Note that since an array type argument (like char*[]) is really just a pointer type argument in disguise, the following two are both valid ways to write (2) and they both mean exactly the same thing:

int main(int argc, char* argv[])
int main(int argc, char** argv)

Some implementations may allow other types and numbers of parameters; you'd have to check the documentation of your implementation to see what it supports.

main() is expected to return zero to indicate success and non-zero to indicate failure. You are not required to explicitly write a return statement in main(): if you let main() return without an explicit return statement, it's the same as if you had written return 0;. The following two main() functions have the same behavior:

int main() { }
int main() { return 0; }

There are two macros, EXIT_SUCCESS and EXIT_FAILURE, defined in <cstdlib> that can also be returned from main() to indicate success and failure, respectively.

The value returned by main() is passed to the exit() function, which terminates the program.

Note that all of this applies only when compiling for a hosted environment (informally, an environment where you have a full standard library and there's an OS running your program). It is also possible to compile a C++ program for a freestanding environment (for example, some types of embedded systems), in which case startup and termination are wholly implementation-defined and a main() function may not even be required. If you're writing C++ for a modern desktop OS, though, you're compiling for a hosted environment.

Reasons I've encountered this error:

1. Did not use .AsNoTracking() when querying for existing entities. Especially when calling a helper function to check permissions.
2. Calling .Include() on a query and then trying to edit the parent. Example: var ent = repo.Query<Ent>().Include(e=>e.Ent2).First(); ...repo.Edit(e.Ent2); repo.Edit(e); If I'm going to edit a nested object, I try to separate these into separate query calls now. If you can't do that, set the child object to null and iterate through lists, detaching objects like this
3. Editing an old entity in a Put web call. The new item is already added to the repo, so modify that one and have it be saved in super.Put(). Example of what will throw an error: public void Put(key, newItem){ var old = repo.Query<Entity>().Where(e=>Id==key).First(); ... repo.Edit(old); super.Put(key,newItem); ... }
4. Multiple helper functions edit the same entity. Instead of passing the ID as a parameter into each function, pass a reference to the entity. Error solved!

In Selenium Java, you can try it using Javascript:

WebDriver driver = new ChromeDriver();_x000D_
_x000D_
if (driver instanceof JavascriptExecutor) {_x000D_
 ((JavascriptExecutor) driver).executeScript("el = document.elementFromPoint(x-cordinate, y-cordinate); el.click();");_x000D_
}

Just say :

git commit --amend -m "New commit message"

and then

git push --force

This works for me when disabling finish Activity animation.

@Override
protected void onPause() {
    super.onPause();
    overridePendingTransition(0, 0);
}

{ } -->

defines scope, so if(a==1) { int b = 10; } says, you are defining int b, for {}- this scope. For

if(a==1)
  int b =10;

there is no scope. And you will not be able to use b anywhere.

Why are you doing this?

 reader = csv.reader(open(filepath, "rU"))

The docs are pretty clear that you must do this:

with open(filepath, "rb") as src:
    reader= csv.reader( src )

The mode must be "rb" to read.

http://docs.python.org/library/csv.html#csv.reader

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

A Nuget solved my problem:Geocoding.Google 4.0.0. Install it so not necessary to write extra classes etc.

https://www.nuget.org/packages/Geocoding.Google/

Since version 3.0 of Jquery you might get an error

TypeError: url.indexOf is not a function

Which can be easily fix by doing

$('#iframe').on('load', function() {
    alert('frame has (re)loaded ');
});

String mQuery = "SELECT Name,Family From tblName";
Cursor mCur = db.rawQuery(mQuery, new String[]{});
mCur.moveToFirst();
while ( !mCur.isAfterLast()) {
        String name= mCur.getString(mCur.getColumnIndex("Name"));
        String family= mCur.getString(mCur.getColumnIndex("Family"));
        mCur.moveToNext();
}

Name and family are your result

strtok doesn't change the parameter itself (str). It stores that pointer (in a local static variable). It can then change what that parameter points to in subsequent calls without having the parameter passed back. (And it can advance that pointer it has kept however it needs to perform its operations.)

From the POSIX strtok page:

This function uses static storage to keep track of the current string position between calls.

There is a thread-safe variant (strtok_r) that doesn't do this type of magic.

I have the same issue, where I want to replace the white space in any pdf file to a dash -. But the files were in multiple sub-directories. So, I had to use os.walk(). In your case for multiple sub-directories, it could be something like this:

import os
for dpath, dnames, fnames in os.walk('/path/to/directory'):
    for f in fnames:
        os.chdir(dpath)
        if f.startswith('cheese_'):
            os.rename(f, f.replace('cheese_', ''))

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

This is a Python 101 type question,

It's a simple question but one where the answer is not so simple.

In python3, a "bytes" object represents a sequence of bytes, a "string" object represents a sequence of unicode code points.

To convert between from "bytes" to "string" and from "string" back to "bytes" you use the bytes.decode and string.encode functions. These functions take two parameters, an encoding and an error handling policy.

Sadly there are an awful lot of cases where sequences of bytes are used to represent text, but it is not necessarily well-defined what encoding is being used. Take for example filenames on unix-like systems, as far as the kernel is concerned they are a sequence of bytes with a handful of special values, on most modern distros most filenames will be UTF-8 but there is no gaurantee that all filenames will be.

If you want to write robust software then you need to think carefully about those parameters. You need to think carefully about what encoding the bytes are supposed to be in and how you will handle the case where they turn out not to be a valid sequence of bytes for the encoding you thought they should be in. Python defaults to UTF-8 and erroring out on any byte sequence that is not valid UTF-8.

print(bytesThing)

Python uses "repr" as a fallback conversion to string. repr attempts to produce python code that will recreate the object. In the case of a bytes object this means among other things escaping bytes outside the printable ascii range.

You really should be using a Ruby version manager.

Using one properly would prevent and can resolve your permission problem when executing a gem update command.

I recommend rbenv.

However, even when you use a Ruby version manager, you may still get that same error message.

If you do, and you are using rbenv, just verify that the ~/.rbenv/shims directory is before the path for the system Ruby.

$ echo $PATH will show you the order of your load path.

If you find that your shims directory comes after your system Ruby bin directory, then edit your ~/.bashrc file and put this as your last export PATH command: export PATH=$HOME/.rbenv/shims:$PATH

$ ruby -v shows you what version of Ruby you are using

This shows that I'm currently using the system version of Ruby (usually not good)

$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

$ rbenv global 1.9.3-p448 switches me to a newer, pre-installed version (see references below).

This shows that I'm using a newer version of Ruby (that likely won't cause the Gem::FilePermissionError)

$ ruby -v
ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.4.0]

You typically should not need to preface a gem command with sudo. If you feel the need to do so, something is probably misconfigured.

For details about rbenv see the following:

• https://github.com/sstephenson/rbenv
• http://robots.thoughtbot.com/post/47273164981/using-rbenv-to-manage-rubies-and-gems

As Kristian has pointed out, good control over z-values will often solve your problems.

If that does not work you can take a look at CSS Box Shadow Bottom Only on using overflow hidden to hide excess shadow.

I would also have in mind that the box-shadow property can accept a comma-separated list of shadows like this:

box-shadow: 0px 10px 5px #888, 0px -10px 5px #888;

This will give you some control over the "amount" of shadow in each direction.

Have a look at http://www.css3.info/preview/box-shadow/ for more information about box-shadow.

Hope this was what you were looking for!

This function should work whichever the locale and currency settings :

function getNumPrice(price, decimalpoint) {
    var p = price.split(decimalpoint);
    for (var i=0;i<p.length;i++) p[i] = p[i].replace(/\D/g,'');
    return p.join('.');
}

This assumes you know the decimal point character (in my case the locale is set from PHP, so I get it with <?php echo cms_function_to_get_decimal_point(); ?>).

Linux/OS X:

Starting from the current directory, recursively find all files ending in .dll or .exe

find . -type f | grep -P "\.dll$|\.exe$"

Starting from the current directory, recursively find all files that DON'T end in .dll or .exe

find . -type f | grep -vP "\.dll$|\.exe$"

Notes:

(1) The P option in grep indicates that we are using the Perl style to write our regular expressions to be used in conjunction with the grep command. For the purpose of excecuting the grep command in conjunction with regular expressions, I find that the Perl style is the most powerful style around.

(2) The v option in grep instructs the shell to exclude any file that satisfies the regular expression

(3) The $ character at the end of say ".dll$" is a delimiter control character that tells the shell that the filename string ends with ".dll"

Use the modulus operator %, it returns the remainder.

int a = 5;
int b = 3;

if (a % b != 0) {
   printf("The remainder is: %i", a%b);
}

If someone is looking for a way to parse float from an arbitrary string,

it can be done like that:

function extractFloat(text) {
  const match = text.match(/\d+((\.|,)\d+)?/)
  return match && match[0]
}

extractFloat('some text with float 5.25') // 5.25

You should use

inputvalue=Math.Round(inputValue, 2, MidpointRounding.AwayFromZero)

Math.Round

Math.Round rounds a double-precision floating-point value to a specified number of fractional digits.

MidpointRounding

Specifies how mathematical rounding methods should process a number that is midway between two numbers.

Basically the function above will take your inputvalue and round it to 2 (or whichever number you specify) decimal places. With MidpointRounding.AwayFromZero when a number is halfway between two others, it is rounded toward the nearest number that is away from zero. There is also another option you can use that rounds towards the nearest even number.

The JWT aud (Audience) Claim

According to RFC 7519:

The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

The Audience (aud) claim as defined by the spec is generic, and is application specific. The intended use is to identify intended recipients of the token. What a recipient means is application specific. An audience value is either a list of strings, or it can be a single string if there is only one aud claim. The creator of the token does not enforce that aud is validated correctly, the responsibility is the recipient's to determine whether the token should be used.

Whatever the value is, when a recipient is validating the JWT and it wishes to validate that the token was intended to be used for its purposes, it MUST determine what value in aud identifies itself, and the token should only validate if the recipient's declared ID is present in the aud claim. It does not matter if this is a URL or some other application specific string. For example, if my system decides to identify itself in aud with the string: api3.app.com, then it should only accept the JWT if the aud claim contains api3.app.com in its list of audience values.

Of course, recipients may choose to disregard aud, so this is only useful if a recipient would like positive validation that the token was created for it specifically.

My interpretation based on the specification is that the aud claim is useful to create purpose-built JWTs that are only valid for certain purposes. For one system, this may mean you would like a token to be valid for some features but not for others. You could issue tokens that are restricted to only a certain "audience", while still using the same keys and validation algorithm.

Since in the typical case a JWT is generated by a trusted service, and used by other trusted systems (systems which do not want to use invalid tokens), these systems simply need to coordinate the values they will be using.

Of course, aud is completely optional and can be ignored if your use case doesn't warrant it. If you don't want to restrict tokens to being used by specific audiences, or none of your systems actually will validate the aud token, then it is useless.

Example: Access vs. Refresh Tokens

One contrived (yet simple) example I can think of is perhaps we want to use JWTs for access and refresh tokens without having to implement separate encryption keys and algorithms, but simply want to ensure that access tokens will not validate as refresh tokens, or vice-versa.

By using aud, we can specify a claim of refresh for refresh tokens and a claim of access for access tokens upon creating these tokens. When a request is made to get a new access token from a refresh token, we need to validate that the refresh token was a genuine refresh token. The aud validation as described above will tell us whether the token was actually a valid refresh token by looking specifically for a claim of refresh in aud.

OAuth Client ID vs. JWT aud Claim

The OAuth Client ID is completely unrelated, and has no direct correlation to JWT aud claims. From the perspective of OAuth, the tokens are opaque objects.

The application which accepts these tokens is responsible for parsing and validating the meaning of these tokens. I don't see much value in specifying OAuth Client ID within a JWT aud claim.

To summarise some of the current options for traversing/filtering JSON data, and provide some syntax examples...

• JSPath
  .automobiles{.maker === "Honda" && .year > 2009}.model

• json:select() (inspired more by CSS selectors)
  .automobiles .maker:val("Honda") .model

• JSONPath (inspired more by XPath)
  $.automobiles[?(@.maker='Honda')].model

I think JSPath looks the nicest, so I'm going to try and integrate it with my AngularJS + CakePHP app.

(I originally posted this answer in another thread but thought it would be useful here, also.)

You could do the opposite of what you proposed.

location (/test)/ {
   set $folder $1;
}

location (/test_/something {
   set $folder $1;
}

One problem with sockets is that they do not have a way to flush the buffer. There is something called the Nagle algorithm which collects all data and flushes it after 40ms. So if it is responsiveness and not bandwidth you might be better off with a pipe.

You can disable the Nagle with the socket option TCP_NODELAY but then the reading end will never receive two short messages in one single read call.

So test it, i ended up with none of this and implemented memory mapped based queues with pthread mutex and semaphore in shared memory, avoiding a lot of kernel system calls (but today they aren't very slow anymore).

That is taking the parameter by reference. So in the first case you are taking a pointer parameter by reference so whatever modification you do to the value of the pointer is reflected outside the function. Second is the simlilar to first one with the only difference being that it is a double pointer. See this example:

void pass_by_value(int* p)
{
    //Allocate memory for int and store the address in p
    p = new int;
}

void pass_by_reference(int*& p)
{
    p = new int;
}

int main()
{
    int* p1 = NULL;
    int* p2 = NULL;

    pass_by_value(p1); //p1 will still be NULL after this call
    pass_by_reference(p2); //p2 's value is changed to point to the newly allocate memory

    return 0;
}

Try:

Iterator<Map.Entry<String,String>> iter = testMap.entrySet().iterator();
while (iter.hasNext()) {
    Map.Entry<String,String> entry = iter.next();
    if("Sample".equalsIgnoreCase(entry.getValue())){
        iter.remove();
    }
}

With Java 1.8 and onwards you can do the above in just one line:

testMap.entrySet().removeIf(entry -> "Sample".equalsIgnoreCase(entry.getValue()));

To create a read-only user, you have to setup a different user than the one owning the tables you want to access.

If you just create the user and grant SELECT permission to the read-only user, you'll need to prepend the schema name to each table name. To avoid this, you have basically two options:

1. Set the current schema in your session:

ALTER SESSION SET CURRENT_SCHEMA=XYZ

2. Create synonyms for all tables:

CREATE SYNONYM READER_USER.TABLE1 FOR XYZ.TABLE1

So if you haven't been told the name of the owner schema, you basically have three options. The last one should always work:

1. Query the current schema setting:

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL

2. List your synonyms:

SELECT * FROM ALL_SYNONYMS WHERE OWNER = USER

3. Investigate all tables (with the exception of the some well-known standard schemas):

SELECT * FROM ALL_TABLES WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'CTXSYS', 'MDSYS');

From (source) one can read:

Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. (..) In computer science, big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size grows.

Big O notation does not represent a function per si but rather a set of functions with a certain asymptotic upper-bound; as one can read from source:

Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.

Informally, in computer-science time-complexity and space-complexity theories, one can think of the Big O notation as a categorization of algorithms with a certain worst-case scenario concerning time and space, respectively. For instance, O(n):

An algorithm is said to take linear time/space, or O(n) time/space, if its time/space complexity is O(n). Informally, this means that the running time/space increases at most linearly with the size of the input (source).

and O(n log n) as:

An algorithm is said to run in quasilinear time/space if T(n) = O(n log^k n) for some positive constant k; linearithmic time/space is the case k = 1 (source).

Nonetheless, typically such relaxed phrasing is normally used to quantify (for the worst-case scenario) how a set of algorithms behaves compared with another set of algorithms regarding the increase of their input sizes. To compare two classes of algorithms (e.g., O(n log n) and O(n)) one should analyze how both classes of algorithms behaves with the increase of their input size (i.e., n) for the worse-case scenario; analyzing n when it tends to the infinity

In the image above big-O denote one of the asymptotically least upper-bounds of the plotted functions, and does not refer to the sets O(f(n)).

For instance comparing O(n log n) vs. O(n) as one can see in the image after a certain input, O(n log n) (green line) grows faster than O(n) (yellow line). That is why (for the worst-case) O(n) is more desirable than O(n log n) because one can increase the input size, and the growth rate will increase slower with the former than with the latter.

The history seem to look like this:

1. Google needs a storage layer for their inverted search index. They figure a traditional RDBMS is not going to cut it. So they implement a NoSQL data store, BigTable on top of their GFS file system. The major part is that thousands of cheap commodity hardware machines provides the speed and the redundancy.

2. Everyone else realizes what Google just did.

3. Brewers CAP theorem is proven. All RDBMS systems of use are CA systems. People begin playing with CP and AP systems as well. K/V stores are vastly simpler, so they are the primary vehicle for the research.

4. Software-as-a-service systems in general do not provide an SQL-like store. Hence, people get more interested in the NoSQL type stores.

I think much of the take-off can be related to this history. Scaling Google took some new ideas at Google and everyone else follows suit because this is the only solution they know to the scaling problem right now. Hence, you are willing to rework everything around the distributed database idea of Google because it is the only way to scale beyond a certain size.

C - Consistency
A - Availability
P - Partition tolerance

Rather than finding top view controller, one can use

viewController.modalPresentationStyle = UIModalPresentationStyle.currentContext

Where viewController is the controller which you want to present This is useful when there are different kinds of views in hierarchy like TabBar, NavBar, though others seems to be correct but more sort of hackish

The other presentation style can be found on apple doc

The better approach uses Shredder's css rule: padding: 0 15px 0 15px only instead of inline css, define a css rule that applies to all tds. Do This by using a style tag in your page:

<style type="text/css">
td
{
    padding:0 15px;
}
</style>

or give the table a class like "paddingBetweenCols" and in the site css use

.paddingBetweenCols td
{
    padding:0 15px;
}

The site css approach defines a central rule that can be reused by all pages.

If your doing to use the site css approach, it would be best to define a class like above and apply the padding to the class...unless you want all td's on the entire site to have the same rule applied.

This issue can even occur when you try to run your project from controller page. Run your project from the jsp page. Go to your jsp page; right-click->Run As->Run on Server. I faced the same issue.I was running my project from the controller page. Run your project from jsp page.

If you change the classes and load the content within the same function you should be fine.

$(document).ready(function(){
    $('.nav li').click(function(event){
        //remove all pre-existing active classes
        $('.active').removeClass('active');

        //add the active class to the link we clicked
        $(this).addClass('active');

        //Load the content
        //e.g.
        //load the page that the link was pointing to
        //$('#content').load($(this).find(a).attr('href'));      

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

You can also try this:

var data= _.reverse(_.sortBy(res.locals.subscriptionList.items, ['type', 'name']));

Delegates Overview

Delegates have the following properties:

• Delegates are similar to C++ function pointers, but are type safe.
• Delegates allow methods to be passed as parameters.
• Delegates can be used to define callback methods.
• Delegates can be chained together; for example, multiple methods can be called on a single event.
• Methods don't need to match the delegate signature exactly. For more information, see Covariance and Contra variance.
• C# version 2.0 introduces the concept of Anonymous Methods, which permit code blocks to be passed as parameters in place of a separately defined method.

AJAX requests are no different from GET and POST requests initiated through a <form> element. Which means you can use $_GET and $_POST to retrieve the data.

When you're making an AJAX request (jQuery example):

// JavaScript file

elements = [1, 2, 9, 15].join(',')
$.post('/test.php', {elements: elements})

It's (almost) equivalent to posting this form:

<form action="/test.php" method="post">
  <input type="text" name="elements" value="1,2,9,15">
</form>

In both cases, on the server side you can read the data from the $_POST variable:

// test.php file

$elements = $_POST['elements'];
$elements = explode(',', $elements);

For the sake of simplicity I'm joining the elements with comma here. JSON serialization is a more universal solution, though.

Typically, for passing arguments to a command line script, you will use either argv global variable or getopt:

// bash command:
//   php -e myscript.php hello
echo $argv[1]; // prints hello

// bash command:
//   php -e myscript.php -f=world
$opts = getopt('f:');
echo $opts['f']; // prints world

$_GET refers to the HTTP GET method parameters, which are unavailable in command line, since they require a web server to populate.

If you really want to populate $_GET anyway, you can do this:

// bash command:
//   export QUERY_STRING="var=value&arg=value" ; php -e myscript.php
parse_str($_SERVER['QUERY_STRING'], $_GET);
print_r($_GET);
/* outputs:
     Array(
        [var] => value
        [arg] => value
     )
*/

You can also execute a given script, populate $_GET from the command line, without having to modify said script:

export QUERY_STRING="var=value&arg=value" ; \
php -e -r 'parse_str($_SERVER["QUERY_STRING"], $_GET); include "index.php";'

Note that you can do the same with $_POST and $_COOKIE as well.

Maybe you want more simple and short approach. This will clear all TextBoxes too. (Except TextBoxes inside Panel or GroupBox).

 foreach (TextBox textBox in Controls.OfType<TextBox>())
    textBox.Text = "";

you can use script module

Example

- name: Transfer and execute a script.
  hosts: all
  tasks:

     - name: Copy and Execute the script 
       script: /home/user/userScript.sh

The essence of the APPLY operator is to allow correlation between left and right side of the operator in the FROM clause.

In contrast to JOIN, the correlation between inputs is not allowed.

Speaking about correlation in APPLY operator, I mean on the right hand side we can put:

• a derived table - as a correlated subquery with an alias
• a table valued function - a conceptual view with parameters, where the parameter can refer to the left side

Both can return multiple columns and rows.

Just use Array.length:

var arr = [];

if (arr.length)
   console.log('not empty');
else
   console.log('empty');

There are many good answers here already, I just want to contribute something from a UX perspective. Keyboard controls in forms are very important.

The question is how to disable from submission on keypress Enter. Not how to ignore Enter in an entire application. So consider attaching the handler to a form element, not the window.

Disabling Enter for form submission should still allow the following:

1. Form submission via Enter when submit button is focused.
2. Form submission when all fields are populated.
3. Interaction with non-submit buttons via Enter.

This is just boilerplate but it follows all three conditions.

$('form').on('keypress', function(e) {
  // Register keypress on buttons.
  $attr = $(e.target).attr('type');
  if ($attr === 'button' || $attr === 'submit') {
    return true;
  }

  // Ignore keypress if all fields are not populated.
  if (e.which === 13 && !fieldsArePopulated(this)) {
    return false;
  }
});

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

You can use this:

function same(a) {
    if (!a.length) return true;
    return !a.filter(function (e) {
        return e !== a[0];
    }).length;
}

The function first checks whether the array is empty. If it is it's values are equals.. Otherwise it filter the array and takes all elements which are different from the first one. If there are no such values => the array contains only equal elements otherwise it doesn't.

To get the right ownership, you can set the group setuid bit on the directory with

chmod g+rwxs dirname

This will ensure that files created in the directory are owned by the group. You should then make sure everyone runs with umask 002 or 007 or something of that nature---this is why Debian and many other linux systems are configured with per-user groups by default.

I don't know of a way to force the permissions you want if the user's umask is too strong.

Personally, I use Emacs with hexl-mod.

Emacs is able to work with really huge files. You can use search/replace value easily. Finally, you can use 'ediff' to do some diffs.

I encountered the same error. My linker command did have the rt library included -lrt which is correct and it was working for a while. After re-installing Kubuntu it stopped working.

A separate forum thread suggested the -lrt needed to come after the project object files. Moving the -lrt to the end of the command fixed this problem for me although I don't know the details of why.

For Transaction in database level

mostly I used @Transactional in DAO's just on method level, so configuration can be specifically for a method / using default (required)

1. DAO's method that get data fetch (select .. ) - don't need @Transactional this can lead to some overhead because of transaction interceptor / and AOP proxy that need to be executed as well.

2. DAO's methods that do insert / update will get @Transactional

very good blog on transctional

For application level -
I am using transactional for business logic I would like to be able rolback in case of unexpected error

@Transactional(rollbackFor={MyApplicationException.class})
public void myMethod(){

    try {    
        //service logic here     
    } catch(Throwable e) {

        log.error(e)
        throw new MyApplicationException(..);
    }
}

I would do this in CSS:

div.centered {
  position: fixed; 
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

then in HTML:

<div class="centered"></div>

More details that help in logging

    String client = request.getRemoteAddr();
    logger.info("###### requested client: {} , Session ID : {} , URI :" + request.getMethod() + ":" + request.getRequestURI() + "", client, request.getSession().getId());

    Map params = request.getParameterMap();
    Iterator i = params.keySet().iterator();
    while (i.hasNext()) {
        String key = (String) i.next();
        String value = ((String[]) params.get(key))[0];
        logger.info("###### Request Param Name : {} , Value :  {} ", key, value);
    }

In my case it did not work in the WSL (Windows Subsystem for Linux).

When I start the WSL, I must

• start ssh-agent_ eval $(ssh-agent -s)
• add the key to the ssh-agent: ssh-add ~/.ssh/id_rsa
• if prompted, enter the password

Now the connection works.
We can test this with ssh -T [email protected]

notes:

• weasel-pageant allows us to reuse the ssh keys that are loaded in PuTTY pageant inside the WSL
• detailed explanation: Git via SSH from Windows returns Permission Denied

Check your real my.ini file location and set --defaults-file="location" with this command

mysql --defaults-file="C:\MYSQL\my.ini" -u root -p

This solution is permanently for your cmd Screen.

The proper way to do it is using the ng-options directive. The HTML would look like this.

<select ng-model="selectedTestAccount" 
        ng-options="item.Id as item.Name for item in testAccounts">
    <option value="">Select Account</option>
</select>

JavaScript:

angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
    $scope.selectedTestAccount = null;
    $scope.testAccounts = [];

    $http({
            method: 'GET',
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 }
        }).success(function (result) {
        $scope.testAccounts = result;
    });
});

You'll also need to ensure angular is run on your html and that your module is loaded.

<html ng-app="test">
    <body ng-controller="DemoCtrl">
    ....
    </body>
</html>

It is not recursion, it is overloading. The two add methods (the one in your snippet, and the one "provided" by ArrayList that you are extending) are not the same method, cause they are declared with different parameters.

Here is a function to convert UNICODE (ISO_8859_1) to UTF-8

public static String String_ISO_8859_1To_UTF_8(String strISO_8859_1) {
final StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < strISO_8859_1.length(); i++) {
  final char ch = strISO_8859_1.charAt(i);
  if (ch <= 127) 
  {
      stringBuilder.append(ch);
  }
  else 
  {
      stringBuilder.append(String.format("%02x", (int)ch));
  }
}
String s = stringBuilder.toString();
int len = s.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
    data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                         + Character.digit(s.charAt(i+1), 16));
}
String strUTF_8 =new String(data, StandardCharsets.UTF_8);
return strUTF_8;
}

TEST

String strA_ISO_8859_1_i = new String("??????".getBytes(StandardCharsets.UTF_8), StandardCharsets.ISO_8859_1);

System.out.println("ISO_8859_1 strA est = "+ strA_ISO_8859_1_i + "\n String_ISO_8859_1To_UTF_8 = " + String_ISO_8859_1To_UTF_8(strA_ISO_8859_1_i));

RESULT

ISO_8859_1 strA est = اÙغÙا٠String_ISO_8859_1To_UTF_8 = ??????

AWS SNS is a publisher subscriber network, where subscribers can subscribe to topics and will receive messages whenever a publisher publishes to that topic.

AWS SQS is a queue service, which stores messages in a queue. SQS cannot deliver any messages, where an external service (lambda, EC2, etc.) is needed to poll SQS and grab messages from SQS.

SNS and SQS can be used together for multiple reasons.

1. There may be different kinds of subscribers where some need the immediate delivery of messages, where some would require the message to persist, for later usage via polling. See this link.

2. The "Fanout Pattern." This is for the asynchronous processing of messages. When a message is published to SNS, it can distribute it to multiple SQS queues in parallel. This can be great when loading thumbnails in an application in parallel, when images are being published. See this link.

3. Persistent storage. When a service that is going to process a message is not reliable. In a case like this, if SNS pushes a notification to a Service, and that service is unavailable, then the notification will be lost. Therefore we can use SQS as a persistent storage and then process it afterwards.

If your table columns contains duplicate data and If you directly apply row_ number() and create PARTITION on column, there is chance to have result in duplicated row and with row number value.

To remove duplicate row, you need one more INNER query in from clause which eliminates duplicate rows and then it will give output to it's foremost outer FROM clause where you can apply PARTITION and ROW_NUMBER ().

As like below example:

SELECT DATE, STATUS, TITLE, ROW_NUMBER() OVER (PARTITION BY DATE, STATUS, TITLE ORDER BY QUANTITY ASC) AS Row_Num
FROM (
     SELECT DISTINCT <column names>...
) AS tbl

This should get the id added.

ASP.NET MVC 5 and lower:

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))
   { } %>

ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id.

<form asp-controller="Account" asp-action="Register" method="post" id="signupform" role="form"></form>

Something missing from gipinani's answer

@Scheduled(cron = "0 1 1,13 * * ?", zone = "CST")

This will execute at 1.01 and 13.01. It can be used when you need to run the job without a pattern multiple times a day.

And the zone attribute is very useful, when you do deployments in remote servers. This was introduced with spring 4.

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Fiddle to your heart's content

HTML

<div>
<a tabindex="1" class="testA">Test A</a> | <a tabindex="2" class="testB">Test B</a>
<div class="hiddendiv" id="testA">1</div>
<div class="hiddendiv" id="testB">2</div>
</div>

CSS

.hiddendiv {display: none; }
.testA:focus ~ #testA {display: block; }
.testB:focus ~ #testB {display: block; }

Benefits

You can put your menu links horizontally = one after the other in HTML code, and then you can put all the content one after another in the HTML code, after the menu.

In other words - other solutions offer an accordion approach where you click a link and the content appears immediately after the link. The next link then appears after that content.

With this approach you don't get the accordion effect. Rather, all links remain in a fixed position and clicking any link simply updates the displayed content. There is also no limitation on content height.

How it works

In your HTML, you first have a DIV. Everything else sits inside this DIV. This is important - it means every element in your solution (in this case, A for links, and DIV for content), is a sibling to every other element.

Secondly, the anchor tags (A) have a tabindex property. This makes them clickable and therefore they can get focus. We need that for the CSS to work. These could equally be DIVs but I like using A for links - and they'll be styled like my other anchors.

Third, each menu item has a unique class name. This is so that in the CSS we can identify each menu item individually.

Fourth, every content item is a DIV, and has the class="hiddendiv". However each each content item has a unique id.

In your CSS, we set all .hiddendiv elements to display:none; - that is, we hide them all.

Secondly, for each menu item we have a line of CSS. This means if you add more menu items (ie. and more hidden content), you will have to update your CSS, yes.

Third, the CSS is saying that when .testA gets focus (.testA:focus) then the corresponding DIV, identified by ID (#testA) should be displayed.

Last, when I just said "the corresponding DIV", the trick here is the tilde character (~) - this selector will select a sibling element, and it does not have to be the very next element, that matches the selector which, in this case, is the unique ID value (#testA).

It is this tilde that makes this solution different than others offered and this lets you simply update some "display panel" with different content, based on clicking one of those links, and you are not as constrained when it comes to where/how you organise your HTML. All you need, though, is to ensure your hidden DIVs are contained within the same parent element as your clickable links.

Season to taste.

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

Or, if you prefer it the other way around:

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

To preserve the order:

def f(seq): # Order preserving
  ''' Modified version of Dave Kirby solution '''
  seen = set()
  return [x for x in seq if x not in seen and not seen.add(x)]

OK, now how does it work, because it's a little bit tricky here if x not in seen and not seen.add(x):

In [1]: 0 not in [1,2,3] and not print('add')
add
Out[1]: True

Why does it return True? print (and set.add) returns nothing:

In [3]: type(seen.add(10))
Out[3]: <type 'NoneType'>

and not None == True, but:

In [2]: 1 not in [1,2,3] and not print('add')
Out[2]: False

Why does it print 'add' in [1] but not in [2]? See False and print('add'), and doesn't check the second argument, because it already knows the answer, and returns true only if both arguments are True.

More generic version, more readable, generator based, adds the ability to transform values with a function:

def f(seq, idfun=None): # Order preserving
  return list(_f(seq, idfun))

def _f(seq, idfun=None):  
  ''' Originally proposed by Andrew Dalke '''
  seen = set()
  if idfun is None:
    for x in seq:
      if x not in seen:
        seen.add(x)
        yield x
  else:
    for x in seq:
      x = idfun(x)
      if x not in seen:
        seen.add(x)
        yield x

Without order (it's faster):

def f(seq): # Not order preserving
  return list(set(seq))

SUM(IF(PaymentType = "credit card", totalamount, 0)) AS CreditCardTotal

Candidate Key: The candidate key can be defined as minimal set of attribute which can uniquely identify a tuple is known as candidate key. For Example, STUD_NO in below STUDENT relation.

• The value of Candidate Key is unique and non-null for every tuple.
• There can be more than one candidate key in a relation. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT.
• The candidate key can be simple (having only one attribute) or composite as well. For Example, {STUD_NO, COURSE_NO} is a composite
  candidate key for relation STUDENT_COURSE.

Super Key: The set of attributes which can uniquely identify a tuple is known as Super Key. For Example, STUD_NO, (STUD_NO, STUD_NAME) etc. Adding zero or more attributes to candidate key generates super key. A candidate key is a super key but vice versa is not true. Primary Key: There can be more than one candidate key in a relation out of which one can be chosen as primary key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_NO can be chosen as primary key (only one out of many candidate keys).

Alternate Key: The candidate key other than primary key is called as alternate key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_PHONE will be alternate key (only one out of many candidate keys).

Foreign Key: If an attribute can only take the values which are present as values of some other attribute, it will be foreign key to the attribute to which it refers. The relation which is being referenced is called referenced relation and corresponding attribute is called referenced attribute and the relation which refers to referenced relation is called referencing relation and corresponding attribute is called referencing attribute. Referenced attribute of referencing attribute should be primary key. For Example, STUD_NO in STUDENT_COURSE is a foreign key to STUD_NO in STUDENT relation.

C# developer working on Windows here. What works for me is simply download the file eng.traineddata from the following URL:

https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata

and copy it to the following directory in my Console Application project:

[Project Directory]\bin\Debug\tessdata

I did manually create the tessdata folder above.

Escape the apostrophe in O'Neal by writing O''Neal (two apostrophes).

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

.left {
  float: left;
  width: 125px;
  text-align: right;
  margin: 2px 10px;
  display: inline;
}

.right {
  float: left;
  text-align: left;
  margin: 2px 10px;
  display: inline;
}

Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.

a = {}
k = 0
while k < 10:
    <dynamically create key> 
    key = ...
    <calculate value> 
    value = ...
    a[key] = value 
    k += 1

There are also some interesting data structures in the new 'collections' module that might be applicable:

http://docs.python.org/dev/library/collections.html

fastest one:

$("div#selected ul li").length

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

i've solve all with

.setInputType(InputType.TYPE_CLASS_NUMBER);

for see clear data and

.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

for see the dots (if the data is a number, it isn't choice che other class)

It can be done by using ecapture First, run

pip install ecapture

Then in a new python script type:

    from ecapture import ecapture as ec

    ec.capture(0,"test","img.jpg")

Start your activity with request code :

StartActivityForResult(intent,1234);

And you can close it from any other activity like this :

finishActivity(1234);

I guess I found a simpler solution

temp1 = pd.melt(df1, id_vars=["location"], var_name='Date', value_name='Value')
temp2 = pd.melt(df1, id_vars=["name"], var_name='Date', value_name='Value')

Concat whole temp1 with temp2's column name

temp1['new_column'] = temp2['name']

You now have what you asked for.

If the divs are hidden, they will never trigger the mouseover event.

You will have to listen to the event of some other unhidden element.

You can consider wrapping your hidden divs into container divs that remain visible, and then act on the mouseover event of these containers.

<div style="width: 80px; height: 20px; background-color: red;" _x000D_
        onmouseover="document.getElementById('div1').style.display = 'block';">_x000D_
   <div id="div1" style="display: none;">Text</div>_x000D_
</div>

You could also listen for the mouseout event if you want the div to disappear when the mouse leaves the container div:

onmouseout="document.getElementById('div1').style.display = 'none';"

Wrapping it with div should work. I tested it in Firefox, Chrome on Fedora 13 (demo).

#content {
   width: 95%;
   height: 95%;
   margin: auto;
}

#myCanvas {
   width: 100%;
   height: 100%;
   border: 1px solid black;
}

And the canvas should be enclosed in tag

<div id="content">
    <canvas id="myCanvas">Your browser doesn't support canvas tag</canvas>
</div>

Let me know if it works. Cheers.

Check the -R option

chmod -R <permissionsettings> <dirname>

In the future, you can save a lot of time by checking the man page first:

man <command name>

So in this case:

man chmod

If you are using Spring Framework, you can use Spring TagLib and SpEL:

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
---
<spring:eval var="containsValue" expression="mylist.contains(myValue)" />
<c:if test="${containsValue}">style='display:none;'</c:if>

It is called the extended call syntax. From the documentation:

If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments; if there are positional arguments x1,..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

and:

If the syntax **expression appears in the function call, expression must evaluate to a mapping, the contents of which are treated as additional keyword arguments. In the case of a keyword appearing in both expression and as an explicit keyword argument, a TypeError exception is raised.

Edit: 2015-10-26: thanks for the upvotes - but take a look at tchrist's answer, especially if you develop for the web or something more "international".

Oren Trutners answer isn't quite right (see sample input of "RightHerE" which must be matched but isn't)

Here is the correct solution:

(?!^.*[A-Z]{2,}.*$)^[A-Za-z]*$

edit:

(?!^.*[A-Z]{2,}.*$)  // don't match the whole expression if there are two or more consecutive uppercase letters
^[A-Za-z]*$          // match uppercase and lowercase letters

/edit

the key for the solution is a negative lookahead see: http://www.regular-expressions.info/lookaround.html

Just git rm subdir will be ok. that will remove the subdir as an index.

A recursive function is a function that contains a call to itself. A recursive struct is a struct that contains an instance of itself. You can combine the two as a recursive class. The key part of a recursive item is that it contains an instance/call of itself.

Consider two mirrors facing each other. We've seen the neat infinity effect they make. Each reflection is an instance of a mirror, which is contained within another instance of a mirror, etc. The mirror containing a reflection of itself is recursion.

A binary search tree is a good programming example of recursion. The structure is recursive with each Node containing 2 instances of a Node. Functions to work on a binary search tree are also recursive.

It works like this. View.OnClickListenere is defined -

public interface OnClickListener {
    void onClick(View v);
}

As far as we know you cannot instantiate an object OnClickListener, as it doesn't have a method implemented. So there are two ways you can go by - you can implement this interface which will override onClick method like this:

public class MyListener implements View.OnClickListener {
    @Override
    public void onClick (View v) {
         // your code here;
    }
}

But it's tedious to do it each time as you want to set a click listener. So in order to avoid this you can provide the implementation for the method on spot, just like in an example you gave.

setOnClickListener takes View.OnClickListener as its parameter.

Thanks to your comments. I've made a function that give an error message when it happens:

/**
 * Replaces a string in a file
 *
 * @param string $FilePath
 * @param string $OldText text to be replaced
 * @param string $NewText new text
 * @return array $Result status (success | error) & message (file exist, file permissions)
 */
function replace_in_file($FilePath, $OldText, $NewText)
{
    $Result = array('status' => 'error', 'message' => '');
    if(file_exists($FilePath)===TRUE)
    {
        if(is_writeable($FilePath))
        {
            try
            {
                $FileContent = file_get_contents($FilePath);
                $FileContent = str_replace($OldText, $NewText, $FileContent);
                if(file_put_contents($FilePath, $FileContent) > 0)
                {
                    $Result["status"] = 'success';
                }
                else
                {
                   $Result["message"] = 'Error while writing file';
                }
            }
            catch(Exception $e)
            {
                $Result["message"] = 'Error : '.$e;
            }
        }
        else
        {
            $Result["message"] = 'File '.$FilePath.' is not writable !';
        }
    }
    else
    {
        $Result["message"] = 'File '.$FilePath.' does not exist !';
    }
    return $Result;
}

According to cppreference, nullptr is a keyword that:

denotes the pointer literal. It is a prvalue of type std::nullptr_t. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. Similar conversions exist for any null pointer constant, which includes values of type std::nullptr_t as well as the macro NULL.

So nullptr is a value of a distinct type std::nullptr_t, not int. It implicitly converts to the null pointer value of any pointer type. This magic happens under the hood for you and you don't have to worry about its implementation. NULL, however, is a macro and it is an implementation-defined null pointer constant. It's often defined like this:

#define NULL 0

i.e. an integer.

This is a subtle but important difference, which can avoid ambiguity.

For example:

int i = NULL;     //OK
int i = nullptr;  //error
int* p = NULL;    //OK
int* p = nullptr; //OK

and when you have two function overloads like this:

void func(int x);   //1)
void func(int* x);  //2)

func(NULL) calls 1) because NULL is an integer. func(nullptr) calls 2) because nullptr converts implicitly to a pointer of type int*.

Also if you see a statement like this:

auto result = findRecord( /* arguments */ );

if (result == nullptr)
{
 ...
}

and you can't easily find out what findRecord returns, you can be sure that result must be a pointer type; nullptr makes this more readable.

In a deduced context, things work a little differently. If you have a template function like this:

template<typename T>
void func(T *ptr)
{
    ...
}

and you try to call it with nullptr:

func(nullptr);

you will get a compiler error because nullptr is of type nullptr_t. You would have to either explicitly cast nullptr to a specific pointer type or provide an overload/specialization for func with nullptr_t.

• avoid ambiguity between function overloads
• enables you to do template specialization
• more secure, intuitive and expressive code, e.g. if (ptr == nullptr) instead of if (ptr == 0)

String str[] = {"aa", "55"};

byte b[] = new byte[str.length];

for (int i = 0; i < str.length; i++) {
    b[i] = (byte) Integer.parseInt(str[i], 16);
}

Integer.parseInt(string, radix) converts a string into an integer, the radix paramter specifies the numeral system.

Use a radix of 16 if the string represents a hexadecimal number.
Use a radix of 2 if the string represents a binary number.
Use a radix of 10 (or omit the radix paramter) if the string represents a decimal number.

For further details check the Java docs: https://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#parseInt(java.lang.String,%20int)

You can also use query which is very readable in my opinion and straightforward to use:

import pandas as pd

df = pd.DataFrame({'A': [1, 2, 3, 4], 'B': [10, 20, 50, 80], 'C': [6, 7, 8, 9]})
df = df.set_index(['A', 'B'])

      C
A B    
1 10  6
2 20  7
3 50  8
4 80  9

For what you had in mind you can now simply do:

df.query('A == 1')

      C
A B    
1 10  6

You can also have more complex queries using and

df.query('A >= 1 and B >= 50')

      C
A B    
3 50  8
4 80  9

and or

df.query('A == 1 or B >= 50')

      C
A B    
1 10  6
3 50  8
4 80  9

You can also query on different index levels, e.g.

df.query('A == 1 or C >= 8')

will return

      C
A B    
1 10  6
3 50  8
4 80  9

If you want to use variables inside your query, you can use @:

b_threshold = 20
c_threshold = 8

df.query('B >= @b_threshold and C <= @c_threshold')

      C
A B    
2 20  7
3 50  8

This is happening because there is no package cache in the image, you need to run:

apt-get -qq update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -qq -y install curl

After that install ZSH and GIT Core:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird since sh does not understand the source command. So, you do this to install zsh:

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh:

chsh -s `which zsh`

and then restart:

sudo shutdown -r 0

This problem is explained in depth in this issue.

Try the RoundUp function:

Dim i As Double

i = Application.WorksheetFunction.RoundUp(Cells(1, 1).Value * Cells(1, 2).Value, 2)

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

and if data in "age" column has similar records (i.e. many people are 25 years old, many others are 32 and so on), it causes confusion in aligning right count to each student. in order to avoid it, I joined the tables on student ID as well.

SELECT S.id, S.age, C.cnt
FROM Students S 
INNER JOIN (SELECT id, age, count(age) as cnt  FROM Students GROUP BY student,age) 
C ON S.age = C.age *AND S.id = C.id*

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

Unfortunately inline elements (or elements having display:inline) ignore the width property. You should use floating divs instead:

<style type="text/css">
div.f1 { float: left; width: 20px; }
div.f2 { float: left; }
div.f3 { clear: both; }
</style>

<div class="f1"></div><div class="f2">The Lazy dog</div><div class="f3"></div>
<div class="f1">AND</div><div class="f2">The Lazy cat</div><div class="f3"></div>
<div class="f1">OR</div><div class="f2">The active goldfish</div><div class="f3"></div>

Now I see you need to use spans and lists, so we need to rewrite this a little bit:

<html><head>
<style type="text/css">
        span.f1 { display: block; float: left; clear: left; width: 60px; }
    li { list-style-type: none; }
    </style>

</head><body>
<ul>
<li><span class="f1">&nbsp;</span>The lazy dog.</li>
<li><span class="f1">AND</span> The lazy cat.</li>
<li><span class="f1">OR</span> The active goldfish.</li>
</ul>
</body>
</html>

Had a similar problem and was getting the following errors depending on what app I used and if we bypassed the firewall / load balancer or not:

HTTPS handshake to [blah] (for #136) failed. System.IO.IOException Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

and

ReadResponse() failed: The server did not return a complete response for this request. Server returned 0 bytes.

The problem turned out to be that the SSL Server Certificate got missed and wasn't installed on a couple servers.

You can use model.predict() to predict the class of a single image as follows [doc]:

# load_model_sample.py
from keras.models import load_model
from keras.preprocessing import image
import matplotlib.pyplot as plt
import numpy as np
import os


def load_image(img_path, show=False):

    img = image.load_img(img_path, target_size=(150, 150))
    img_tensor = image.img_to_array(img)                    # (height, width, channels)
    img_tensor = np.expand_dims(img_tensor, axis=0)         # (1, height, width, channels), add a dimension because the model expects this shape: (batch_size, height, width, channels)
    img_tensor /= 255.                                      # imshow expects values in the range [0, 1]

    if show:
        plt.imshow(img_tensor[0])                           
        plt.axis('off')
        plt.show()

    return img_tensor


if __name__ == "__main__":

    # load model
    model = load_model("model_aug.h5")

    # image path
    img_path = '/media/data/dogscats/test1/3867.jpg'    # dog
    #img_path = '/media/data/dogscats/test1/19.jpg'      # cat

    # load a single image
    new_image = load_image(img_path)

    # check prediction
    pred = model.predict(new_image)

In this example, a image is loaded as a numpy array with shape (1, height, width, channels). Then, we load it into the model and predict its class, returned as a real value in the range [0, 1] (binary classification in this example).

This is how it works fine to me:

var things = [
    { id: 1, color: 'yellow' },
    { id: 2, color: 'blue' },
    { id: 3, color: 'red' }

You need to select both Match Case and Regular Expressions for regex expressions with case. Else [A-Z] won't work.enter image description here

Path.GetDirectoryName()... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).

You could validate first by testing File.Exists() and/or Directory.Exists() on your path first to see if you need to call Path.GetDirectoryName

Creating Tags

Git uses two main types of tags: lightweight and annotated.

Annotated Tags:

To create an annotated tag in Git you can just run the following simple commands on your terminal.

$ git tag -a v2.1.0 -m "xyz feature is released in this tag."
$ git tag
v1.0.0
v2.0.0
v2.1.0

The -m denotes message for that particular tag. We can write summary of features which is going to tag here.

Lightweight Tags:

The other way to tag commits is lightweight tag. We can do it in the following way:

$ git tag v2.1.0
$ git tag
v1.0.0
v2.0.0
v2.1.0

Push Tag

To push particular tag you can use below command:

git push origin v1.0.3

Or if you want to push all tags then use the below command:

git push --tags

List all tags:

To list all tags, use the following command.

git tag

this answer helped me out a lot and pointed me in the right direction but what worked for me, and hopefully others, is:

menuApp.controller("dynamicMenuController", function($scope, $http) {
$scope.appetizers= [];
$http.get('config/menu.json').success(function(data) { 
    console.log("success!");
    $scope.appetizers = data.appetizers;
        console.log(data.appetizers);
    });    
});

There is no correct answer, since it depends on what the definition of "syntax" is for your request. The most important thing is that you:

1. Use the response code(s) consistently
2. Include as much additional information in the response body as you can to help the developer(s) using your API figure out what's going on.=

Before everyone jumps all over me for saying that there is no right or wrong answer here, let me explain a bit about how I came to the conclusion.

In this specific example, the OP's question is about a JSON request that contains a different key than expected. Now, the key name received is very similar, from a natural language standpoint, to the expected key, but it is, strictly, different, and hence not (usually) recognized by a machine as being equivalent.

As I said above, the deciding factor is what is meant by syntax. If the request was sent with a Content Type of application/json, then yes, the request is syntactically valid because it's valid JSON syntax, but not semantically valid, since it doesn't match what's expected. (assuming a strict definition of what makes the request in question semantically valid or not).

If, on the other hand, the request was sent with a more specific custom Content Type like application/vnd.mycorp.mydatatype+json that, perhaps, specifies exactly what fields are expected, then I would say that the request could easily be syntactically invalid, hence the 400 response.

In the case in question, since the key was wrong, not the value, there was a syntax error if there was a specification for what valid keys are. If there was no specification for valid keys, or the error was with a value, then it would be a semantic error.

Would the use of <caption> be allowed?

<ul>
  <caption> Title of List </caption>
  <li> Item 1 </li>
  <li> Item 2 </li>
</ul>

.row {
    letter-spacing: -.31em;
    word-spacing: -.43em;
}
.col-md-4 {
    float: none;
    display: inline-block;
    vertical-align: middle;
}

Note: .col-md-4 could be any grid column, its just an example here.

Trim() will only remove leading or trailing spaces.

Try .Contains() to check if a string contains white space

"sossjjs sskkk".Contains(" ") // returns true

Try this:

df.my_channel = df.my_channel.where(df.my_channel <= 20000, other= 0)

or

df.my_channel = df.my_channel.mask(df.my_channel > 20000, other= 0)

According to php.net the Salt option has been deprecated as of PHP 7.0.0, so you should use the salt that is generated by default and is far more simpler

Example for store the password:

$hashPassword = password_hash("password", PASSWORD_BCRYPT);

Example to verify the password:

$passwordCorrect = password_verify("password", $hashPassword);

Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

Also this could be that you have forgotten to set your working directory in eclipse to be the correct local for the application to run in.

If a <script> has a src then the text content of the element will be not be executed as JS (although it will appear in the DOM).

You need to use multiple script elements.

1. a <script> to load the external script

2. a <script> to hold your inline code (with the call to the function in the external script)

@AmitKB, Your procedure is correct. Although this error

Query error: #1075 - Incorrect table definition; there can be only one auto column and it must be defined as a key

can be solved by first marking the field as key(using the key icon with label primary),unless you have other key then it may not work.

I had this problem. I think that it was caused by the socket getting opened and no data arriving within a short time after the open. I was reading from a serial to ethernet box called a Devicemaster. I changed the Devicemaster port setting from "connect always" to "connect on data" and the problem disappeared. I have great respect for Hans Passant but I do not agree that this is an error code that you can easily solve by scrutinizing code.

That’s right, Executors.newCachedThreadPool() isn't a great choice for server code that's servicing multiple clients and concurrent requests.

Why? There are basically two (related) problems with it:

1. It's unbounded, which means that you're opening the door for anyone to cripple your JVM by simply injecting more work into the service (DoS attack). Threads consume a non-negligible amount of memory and also increase memory consumption based on their work-in-progress, so it's quite easy to topple a server this way (unless you have other circuit-breakers in place).

2. The unbounded problem is exacerbated by the fact that the Executor is fronted by a SynchronousQueue which means there's a direct handoff between the task-giver and the thread pool. Each new task will create a new thread if all existing threads are busy. This is generally a bad strategy for server code. When the CPU gets saturated, existing tasks take longer to finish. Yet more tasks are being submitted and more threads created, so tasks take longer and longer to complete. When the CPU is saturated, more threads is definitely not what the server needs.

Here are my recommendations:

Use a fixed-size thread pool Executors.newFixedThreadPool or a ThreadPoolExecutor. with a set maximum number of threads;

Okay, let's re-iterate...

The actual question (and an excellent one at that)

"What does 'run as admin' do that being a member of the administrators group does not?"

(Answer)1. It allows you to call on administrator rights while under a user session.

Note: The question is wrongly put; one is a command and the other is a group object to apply policies.

Open a command prompt and type runas /?.

This will list all the switches the runas command line can use.

As for the Administrators Group this is based on GPEDIT or SECPOL and whether or not a Domain administrator is present or not or a network is present or not.

Usually these things will apply restrictions on computers that the administrators group is not affected by.

The question should be

What does runas admin do that run as user does not?

OR

What does the Administrator group do that a customized user group can't?

You are mixing apples and oranges.

On MySQL 8.0.4+

To update current root user:

select current_user();
set password = 'new_password';

To update other user:

set password for 'otherUser'@'localhost' = 'new_password';

To set password policy before updating password:

set global validate_password.policy = 0;
set password = 'new_password';
set password for 'otherUser'@'localhost' = 'new_password';

Other / better way to update root password:

mysql_secure_installation

Want to stick with 5.x authentication so you can still use legacy apps?

On my.cnf

default_authentication_plugin = mysql_native_password

To update root:

set global validate_password.policy = 0;
alter user 'root'@'localhost' identified with mysql_native_password by 'new_password';

where java works for me to list all java exe but java -verbose tells you which rt.jar is used and thus which jre (full path):

[Opened C:\Program Files\Java\jre6\lib\rt.jar]
...

Edit: win7 and java:

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

select   UserId,max(Date) over (partition by UserId) value from users;

char c = '5'

A char (1 byte) is allocated on stack at address 0x12345678.

char *d = &c;

You obtain the address of c and store it in d, so d = 0x12345678.

int *e = (int*)d;

You force the compiler to assume that 0x12345678 points to an int, but an int is not just one byte (sizeof(char) != sizeof(int)). It may be 4 or 8 bytes according to the architecture or even other values.

So when you print the value of the pointer, the integer is considered by taking the first byte (that was c) and other consecutive bytes which are on stack and that are just garbage for your intent.

For me, it wasn't just getting the javadoc window to open, but also getting the complete javadoc to present. You may still get a sparse javadoc that is based solely on the method signature if you are importing libraries from a Maven repository and do not tell Idea to include the javadocs in the download. Be sure to tick the "JavaDocs" option in the "Download Library From Maven Repository" dialog, which can be found under Project Structure -> Projtect Settings -> Libraries.

Here is a very simple jade file that have a loop in it. Jade is very sensitive about white space. After loop definition line (for) you should give an indent(tab) to stuff that want to go inside the loop. You can do this without {}:

- var arr=['one', 'two', 'three'];
- var s = 'string';
doctype html
html
    head
    body
        section= s
        - for (var i=0; i<3; i++)
            div= arr[i]

Use:

mysqldump --extended-insert=FALSE 

Be aware that multiple inserts will be slower than one big insert.

The most intuitive way of doing this without using literals or regular expressions:

yourString.replaceAll(" ","");

List<ProjectResources> list = new List<ProjectResources>();        
IList<ProjectResources> obj = `Your Data Will Be Here`;
list = obj.ToList<ProjectResources>();

This Would Convert IList Object to List Object.

I met the issue before when using a fullscreen dialogFragment: there is always a padding while having set fullscreen. try this code in dialogFragment's onActivityCreated() method:

public void onActivityCreated(Bundle savedInstanceState)
{   
    super.onActivityCreated(savedInstanceState);
    Window window = getDialog().getWindow();
    LayoutParams attributes = window.getAttributes();
    //must setBackgroundDrawable(TRANSPARENT) in onActivityCreated()
    window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    if (needFullScreen)
    {
        window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    }
}

Very easy to do it ,

Write it at your controller

$this->validate($request,[
     'email'=>['required',Rule::unique('yourTableName')->ignore($request->id)]
]);
Note : Rule::unique('yourTableName')->ignore($idParameter) , here $idParameter you can receive from get url also you can get it from hidden field.
Most important is don't forget to import Rule at the top.

Your if statements are checking for int values. raw_input returns a string. Change the following line:

tSizeAns = raw_input() 

to

tSizeAns = int(raw_input()) 

You can keep your CONTACT parameter with the following approach:

using (var stream = new MemoryStream())
{
    var context = (HttpContextBase)Request.Properties["MS_HttpContext"];
    context.Request.InputStream.Seek(0, SeekOrigin.Begin);
    context.Request.InputStream.CopyTo(stream);
    string requestBody = Encoding.UTF8.GetString(stream.ToArray());
}

Returned for me the json representation of my parameter object, so I could use it for exception handling and logging.

Found as accepted answer here

I am not an expert in HTML but here is what worked for me:

<div class="img-with-text-below">
    <img src="your-image.jpg" alt="alt-text" />
    <p><center>Your text</center></p>
</div>

As of Swift 4 (Xcode 9), the Swift standard library provides methods to convert between Swift string ranges (Range<String.Index>) and NSString ranges (NSRange). Example:

let str = "abc"
let r1 = str.range(of: "")!

// String range to NSRange:
let n1 = NSRange(r1, in: str)
print((str as NSString).substring(with: n1)) // 

// NSRange back to String range:
let r2 = Range(n1, in: str)!
print(str[r2]) // 

Therefore the text replacement in the text field delegate method can now be done as

func textField(_ textField: UITextField,
               shouldChangeCharactersIn range: NSRange,
               replacementString string: String) -> Bool {

    if let oldString = textField.text {
        let newString = oldString.replacingCharacters(in: Range(range, in: oldString)!,
                                                      with: string)
        // ...
    }
    // ...
}

(Older answers for Swift 3 and earlier:)

As of Swift 1.2, String.Index has an initializer

init?(_ utf16Index: UTF16Index, within characters: String)

which can be used to convert NSRange to Range<String.Index> correctly (including all cases of Emojis, Regional Indicators or other extended grapheme clusters) without intermediate conversion to an NSString:

extension String {
    func rangeFromNSRange(nsRange : NSRange) -> Range<String.Index>? {
        let from16 = advance(utf16.startIndex, nsRange.location, utf16.endIndex)
        let to16 = advance(from16, nsRange.length, utf16.endIndex)
        if let from = String.Index(from16, within: self),
            let to = String.Index(to16, within: self) {
                return from ..< to
        }
        return nil
    }
}

This method returns an optional string range because not all NSRanges are valid for a given Swift string.

The UITextFieldDelegate delegate method can then be written as

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

    if let swRange = textField.text.rangeFromNSRange(range) {
        let newString = textField.text.stringByReplacingCharactersInRange(swRange, withString: string)
        // ...
    }
    return true
}

The inverse conversion is

extension String {
    func NSRangeFromRange(range : Range<String.Index>) -> NSRange {
        let utf16view = self.utf16
        let from = String.UTF16View.Index(range.startIndex, within: utf16view) 
        let to = String.UTF16View.Index(range.endIndex, within: utf16view)
        return NSMakeRange(from - utf16view.startIndex, to - from)
    }
}

A simple test:

let str = "abc"
let r1 = str.rangeOfString("")!

// String range to NSRange:
let n1 = str.NSRangeFromRange(r1)
println((str as NSString).substringWithRange(n1)) // 

// NSRange back to String range:
let r2 = str.rangeFromNSRange(n1)!
println(str.substringWithRange(r2)) // 

Update for Swift 2:

The Swift 2 version of rangeFromNSRange() was already given by Serhii Yakovenko in this answer, I am including it here for completeness:

extension String {
    func rangeFromNSRange(nsRange : NSRange) -> Range<String.Index>? {
        let from16 = utf16.startIndex.advancedBy(nsRange.location, limit: utf16.endIndex)
        let to16 = from16.advancedBy(nsRange.length, limit: utf16.endIndex)
        if let from = String.Index(from16, within: self),
            let to = String.Index(to16, within: self) {
                return from ..< to
        }
        return nil
    }
}

The Swift 2 version of NSRangeFromRange() is

extension String {
    func NSRangeFromRange(range : Range<String.Index>) -> NSRange {
        let utf16view = self.utf16
        let from = String.UTF16View.Index(range.startIndex, within: utf16view)
        let to = String.UTF16View.Index(range.endIndex, within: utf16view)
        return NSMakeRange(utf16view.startIndex.distanceTo(from), from.distanceTo(to))
    }
}

Update for Swift 3 (Xcode 8):

extension String {
    func nsRange(from range: Range<String.Index>) -> NSRange {
        let from = range.lowerBound.samePosition(in: utf16)
        let to = range.upperBound.samePosition(in: utf16)
        return NSRange(location: utf16.distance(from: utf16.startIndex, to: from),
                       length: utf16.distance(from: from, to: to))
    }
}

extension String {
    func range(from nsRange: NSRange) -> Range<String.Index>? {
        guard
            let from16 = utf16.index(utf16.startIndex, offsetBy: nsRange.location, limitedBy: utf16.endIndex),
            let to16 = utf16.index(utf16.startIndex, offsetBy: nsRange.location + nsRange.length, limitedBy: utf16.endIndex),
            let from = from16.samePosition(in: self),
            let to = to16.samePosition(in: self)
            else { return nil }
        return from ..< to
    }
}

Example:

let str = "abc"
let r1 = str.range(of: "")!

// String range to NSRange:
let n1 = str.nsRange(from: r1)
print((str as NSString).substring(with: n1)) // 

// NSRange back to String range:
let r2 = str.range(from: n1)!
print(str.substring(with: r2)) // 

In C or C++ local objects are usually allocated on the stack. You are allocating a large array on the stack, more than the stack can handle, so you are getting a stackoverflow.

Don't allocate it local on stack, use some other place instead. This can be achieved by either making the object global or allocating it on the global heap. Global variables are fine, if you don't use the from any other compilation unit. To make sure this doesn't happen by accident, add a static storage specifier, otherwise just use the heap.

This will allocate in the BSS segment, which is a part of the heap:

static int c[1000000];
int main()
{
   cout << "done\n";
   return 0;
}

This will allocate in the DATA segment, which is a part of the heap too:

int c[1000000] = {};
int main()
{
   cout << "done\n";
   return 0;
}

This will allocate at some unspecified location in the heap:

int main()
{
   int* c = new int[1000000];
   cout << "done\n";
   return 0;
}

Once you have obtained the context in your onTap() you can also do:

Intent myIntent = new Intent(mContext, theNewActivity.class);
mContext.startActivity(myIntent);

Method #1

The first method is to replace extra spaces between words with an uncommon symbol combination as a temporary marker. Then you can replace the temporary marker symbols using the replace function rather than a loop.

Here is a code example that replaces text within a String variable.

DECLARE @testString AS VARCHAR(256) = ' Test        text   with  random*        spacing. Please normalize  this spacing!';
SELECT REPLACE(REPLACE(REPLACE(@testString, ' ', '*^'), '^*', ''), '*^', ' ');

Execution Time Test #1: In ten runs of this replacement method, the average wait time on server replies was 1.7 milliseconds and total execution time was 4.6 milliseconds. Execution Time Test #2: The average wait time on server replies was 1.7 milliseconds and total execution time was 3.7 milliseconds.

Method #2

The second method is not quite as elegant as the first, but also gets the job done. This method works by nesting four (or optionally more) replace statements that replace two blank spaces with one blank space.

DECLARE @testString AS VARCHAR(256) = ' Test        text   with  random*        spacing. Please normalize  this spacing!';
SELECT REPLACE(REPLACE(REPLACE(REPLACE(@testString,' ',' '),' ',' '),' ',' '),' ',' ')

Execution Time Test #1: In ten runs of this replacement method, the average wait time on server replies was 1.9 milliseconds and total execution time was 3.8 milliseconds. Execution Time Test #2: The average wait time on server replies was 1.8 milliseconds and total execution time was 4.8 milliseconds.

Method #3

The third method of replacing extra spaces between words is to use a simple loop. You can do a check on extra spaces in a while loop and then use the replace function to reduce the extra spaces with each iteration of the loop.

DECLARE @testString AS VARCHAR(256) = ' Test text with random* spacing. Please normalize this spacing!';
WHILE CHARINDEX(' ',@testString) > 0
SET @testString = REPLACE(@testString, ' ', ' ')
SELECT @testString

Execution Time Test #1: In ten runs of this replacement method, the average wait time on server replies was 1.8 milliseconds and total execution time was 3.4 milliseconds. Execution Time Test #2: The average wait time on server replies was 1.9 milliseconds and total execution time was 2.8 milliseconds.

The example below is based on the html5rocks solution. It uses the browser's FileReader() function. Newer browsers only.

See http://www.html5rocks.com/en/tutorials/file/dndfiles/#toc-reading-files

In this example, the user selects an HTML file. It uploaded into the <textarea>.

<form enctype="multipart/form-data">
<input id="upload" type=file   accept="text/html" name="files[]" size=30>
</form>

<textarea class="form-control" rows=35 cols=120 id="ms_word_filtered_html"></textarea>

<script>
function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // use the 1st file from the list
    f = files[0];

    var reader = new FileReader();

    // Closure to capture the file information.
    reader.onload = (function(theFile) {
        return function(e) {

          jQuery( '#ms_word_filtered_html' ).val( e.target.result );
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsText(f);
  }

  document.getElementById('upload').addEventListener('change', handleFileSelect, false);
</script>

Try json_dto. It is header-only and easy to use.

Simple example:

struct message_t
{
  std::string m_from;
  std::string m_text;

  // Entry point for json_dto.
  template < typename JSON_IO >
  void
  json_io( JSON_IO & io )
  {
    io
      & json_dto::mandatory( "from", m_from )
      & json_dto::mandatory( "text", m_text );
  }
};

This will be convertable to and from JSON:

{ "from" : "json_dto", "text" : "Hello world!" }

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

array_1 = np.array(list_1)

You need to have a doGet method as:

public void doGet(HttpServletRequest request,
        HttpServletResponse response)
throws IOException, ServletException
{
    response.setContentType("text/html");

curl https://bootstrap.pypa.io/get-pip.py | python3.4

Or if you don't have curl for some reason:

wget https://bootstrap.pypa.io/get-pip.py
python3.4 get-pip.py

After this you should be able to run

$ pip3

I had a similar problem what worked for me was to set JAVA_HOME. I tired it first in R:

Sys.setenv(JAVA_HOME = "C:/Program Files/Java/jdk1.8.0_101/")

And when it actually worked I set it in

System Properties -> Advanced -> Environment Variables

by adding a new System variable. I then restarted R/RStudio and everything worked.

EOF is -1 because that's how it's defined. The name is provided by the standard library headers that you #include. They make it equal to -1 because it has to be something that can't be mistaken for an actual byte read by getchar(). getchar() reports the values of actual bytes using positive number (0 up to 255 inclusive), so -1 works fine for this.

The != operator means "not equal". 0 stands for false, and anything else stands for true. So what happens is, we call the getchar() function, and compare the result to -1 (EOF). If the result was not equal to EOF, then the result is true, because things that are not equal are not equal. If the result was equal to EOF, then the result is false, because things that are equal are not (not equal).

The call to getchar() returns EOF when you reach the "end of file". As far as C is concerned, the 'standard input' (the data you are giving to your program by typing in the command window) is just like a file. Of course, you can always type more, so you need an explicit way to say "I'm done". On Windows systems, this is control-Z. On Unix systems, this is control-D.

The example in the book is not "wrong". It depends on what you actually want to do. Reading until EOF means that you read everything, until the user says "I'm done", and then you can't read any more. Reading until '\n' means that you read a line of input. Reading until '\0' is a bad idea if you expect the user to type the input, because it is either hard or impossible to produce this byte with a keyboard at the command prompt :)

include the css file into your blade template in laravel

1. move css file into public->css folder in your laravel project.
2. use <link rel="stylesheet" href="{{ asset('css/filename') }}">

so css is applied in a blade.php file.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

I had the same problem and I solved by using the postcast server. You can install it locally and use it.

__init__ is a special method in Python classes, it is the constructor method for a class. It is called whenever an object of the class is constructed or we can say it initialises a new object. Example:

    In [4]: class A:
   ...:     def __init__(self, a):
   ...:         print(a)
   ...:
   ...: a = A(10) # An argument is necessary
10

If we use A(), it will give an error TypeError: __init__() missing 1 required positional argument: 'a' as it requires 1 argument a because of __init__ .

........

__call__ when implemented in the Class helps us invoke the Class instance as a function call.

Example:

In [6]: class B:
   ...:     def __call__(self,b):
   ...:         print(b)
   ...:
   ...: b = B() # Note we didn't pass any arguments here
   ...: b(20)   # Argument passed when the object is called
   ...:
20

Here if we use B(), it runs just fine because it doesn't have an __init__ function here.

For rails6, I was facing the same problem, as I was missing following files, once I added them, the issue resolved:

1. config/master.key
2. config/credentials.yml.enc

Make sure you have this files.!!!

this should work.

TextView t2 = (TextView) findViewById(R.id.text2);
t2.setMovementMethod(LinkMovementMethod.getInstance());

and

<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="@string/txtCredits"
android:id="@+id/text2"
 android:layout_centerInParent="true"
android:layout_marginTop="20dp"></TextView>

I found this to be more helpfull, since it is an extention, and it allows you to select the source of your code.

static string
    numbers = "0123456789",
    letters = "abcdefghijklmnopqrstvwxyz",
    lettersUp = letters.ToUpper(),
    codeAll = numbers + letters + lettersUp;

static Random m_rand = new Random();

public static string GenerateCode(this int size)
{
    return size.GenerateCode(CodeGeneratorType.All);
}

public static string GenerateCode(this int size, CodeGeneratorType type)
{
    string source;

    if (type == CodeGeneratorType.All)
    {
        source = codeAll;
    }
    else
    {
        StringBuilder sourceBuilder = new StringBuilder();
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.Numbers)
            sourceBuilder.Append(numbers);
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.Letters)
            sourceBuilder.Append(letters);
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.LettersUpperCase)
            sourceBuilder.Append(lettersUp);

        source = sourceBuilder.ToString();
    }

    return size.GenerateCode(source);
}

public static string GenerateCode(this int size, string source)
{
    StringBuilder code = new StringBuilder();
    int maxIndex = source.Length-1;
    for (int i = 0; i < size; i++)
    {

        code.Append(source[Convert.ToInt32(Math.Round(m_rand.NextDouble() * maxIndex))]);
    }

    return code.ToString();
}

public enum CodeGeneratorType { Numbers = 1, Letters = 2, LettersUpperCase = 4, All = 16 };

Hope this helps.

Use ROUND but with num_digits = -1

=ROUND(A1,-1)

Also applies to ROUNDUP and ROUNDDOWN

From Excel help:

• If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places.
• If num_digits is 0, then number is rounded to the nearest integer.
• If num_digits is less than 0, then number is rounded to the left of the decimal point.

EDIT: To get the numbers to always round up use =ROUNDUP(A1,-1)

Just use /\s+/ against '' as a splitter. In this case all "extra" blanks were removed. Usually this particular behaviour is required. So, in you case it will be:

my $line = "file1.gz file1.gz file3.gz";
my @abc = split(/\s+/, $line);

A little bit late but I got the same error and I realized that it was because I copied some code from a PDF. Check the difference between these two: - - The first one is from hitting the minus sign on keyboard and the second is from a latex generated PDF.

You can use the CSS3 Linear Gradient property along with your background-image like this:

#landing-wrapper {
    display:table;
    width:100%;
    background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
    background-position:center top;
    height:350px;
}

Here's a demo:

#landing-wrapper {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
  background-position: center top;_x000D_
  height: 350px;_x000D_
  color: white;_x000D_
}

<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>

Isn't this exactly what squashing a rebase does? Just squash everything except the last commit and then (force) push it.

You don't have to give up simple css :)

.short { max-width: 300px; }

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

Looking for the possibility to put a powershell script into a batch file, I found this thread. The idea of walid2mi did not worked 100% for my script. But via a temporary file, containing the script it worked out. Here is the skeleton of the batch file:

;@echo off
;setlocal ENABLEEXTENSIONS
;rem make from X.bat a X.ps1 by removing all lines starting with ';' 
;Findstr -rbv "^[;]" %0 > %~dpn0.ps1 
;powershell -ExecutionPolicy Unrestricted -File %~dpn0.ps1 %*
;del %~dpn0.ps1
;endlocal
;goto :EOF
;rem Here start your power shell script.
param(
    ,[switch]$help
)

There is $RANDOM. I don't know exactly how it works. But it works. For testing, you can do :

echo $RANDOM

mysqldump will backup by default all the triggers but NOT the stored procedures/functions. There are 2 mysqldump parameters that control this behavior:

• --routines – FALSE by default
• --triggers – TRUE by default

so in mysqldump command , add --routines like :

mysqldump <other mysqldump options> --routines > outputfile.sql

See the MySQL documentation about mysqldump arguments.

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510
1     ok  2.829  1.036  0.751  1.001  0.247  2.456    0.3216
2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0

Actually you can add your table inside a div as its wrapper. and then assign these CSS codes to wrapper:

.table-wrapper {
  border: 1px solid #f00;
  border-radius: 5px;
  overflow: hidden;
}

table {
  border-collapse: collapse;
}

There are indeed C# compilers for Android available. Even though I prefer developing Android Apps in Java, I can recommend MonoForAndroid. You find more information on http://xamarin.com/monoforandroid
