For those of you looking for a Swift 4 solution to this answer, you can use the following to detect a touch event on a UIImageView.

let gestureRecognizer: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageViewTapped))
imageView.addGestureRecognizer(gestureRecognizer)
imageView.isUserInteractionEnabled = true

You will then need to define your selector as follows:

@objc func imageViewTapped() {
    // Image has been tapped
}

Short circuit here means that the second condition won't be evaluated.

If ( A && B ) will result in short circuit if A is False.

If ( A && B ) will not result in short Circuit if A is True.

If ( A || B ) will result in short circuit if A is True.

If ( A || B ) will not result in short circuit if A is False.

Have a look at ConcurrentSkipListMap. It should give you log(n) time for testing and removing an element if it is already contained in the cache, and constant time for re-adding it.

You'd just need some counter etc and wrapper element to force ordering of the LRU order and ensure recent stuff is discarded when the cache is full.

Javascript arrays have a length property. Use it like this:

st.itemb.length

You can add a callback function to your list of get_category(...) parameters.

Ex:

 get_categories(number, callback){
 this.http.post( url, body, {headers: headers, withCredentials:true})
    .subscribe( 
      response => {
        this.total = response.json();
        callback(); 

      }, error => {
    }
  ); 

}

And then you can just call get_category(...) like this:

this.get_category(1, name_of_function);

In C, \0 denotes a character with value zero. The following are identical:

char a = 0;
char b = '\0';

The utility of this escape sequence is greater inside string literals, which are arrays of characters:

char arr[] = "abc\0def\0ghi\0";

(Note that this array has two zero characters at the end, since string literals include a hidden, implicit terminal zero.)

Given say...

std::string x = "hello";

Getting a `char *` or `const char*` from a `string`

How to get a character pointer that's valid while x remains in scope and isn't modified further

C++11 simplifies things; the following all give access to the same internal string buffer:

const char* p_c_str = x.c_str();
const char* p_data  = x.data();
char* p_writable_data = x.data(); // for non-const x from C++17 
const char* p_x0    = &x[0];

      char* p_x0_rw = &x[0];  // compiles iff x is not const...

All the above pointers will hold the same value - the address of the first character in the buffer. Even an empty string has a "first character in the buffer", because C++11 guarantees to always keep an extra NUL/0 terminator character after the explicitly assigned string content (e.g. std::string("this\0that", 9) will have a buffer holding "this\0that\0").

Given any of the above pointers:

char c = p[n];   // valid for n <= x.size()
                 // i.e. you can safely read the NUL at p[x.size()]

Only for the non-const pointer p_writable_data and from &x[0]:

p_writable_data[n] = c;
p_x0_rw[n] = c;  // valid for n <= x.size() - 1
                 // i.e. don't overwrite the implementation maintained NUL

Writing a NUL elsewhere in the string does not change the string's size(); string's are allowed to contain any number of NULs - they are given no special treatment by std::string (same in C++03).

In C++03, things were considerably more complicated (key differences highlighted):

• x.data()

  • returns const char* to the string's internal buffer which wasn't required by the Standard to conclude with a NUL (i.e. might be ['h', 'e', 'l', 'l', 'o'] followed by uninitialised or garbage values, with accidental accesses thereto having undefined behaviour).
    • x.size() characters are safe to read, i.e. x[0] through x[x.size() - 1]
    • for empty strings, you're guaranteed some non-NULL pointer to which 0 can be safely added (hurray!), but you shouldn't dereference that pointer.

• &x[0]

  • for empty strings this has undefined behaviour (21.3.4)
    • e.g. given f(const char* p, size_t n) { if (n == 0) return; ...whatever... } you mustn't call f(&x[0], x.size()); when x.empty() - just use f(x.data(), ...).
  • otherwise, as per x.data() but:
    • for non-const x this yields a non-const char* pointer; you can overwrite string content

• x.c_str()

  • returns const char* to an ASCIIZ (NUL-terminated) representation of the value (i.e. ['h', 'e', 'l', 'l', 'o', '\0']).
  • although few if any implementations chose to do so, the C++03 Standard was worded to allow the string implementation the freedom to create a distinct NUL-terminated buffer on the fly, from the potentially non-NUL terminated buffer "exposed" by x.data() and &x[0]
  • x.size() + 1 characters are safe to read.
  • guaranteed safe even for empty strings (['\0']).

Consequences of accessing outside legal indices

Whichever way you get a pointer, you must not access memory further along from the pointer than the characters guaranteed present in the descriptions above. Attempts to do so have undefined behaviour, with a very real chance of application crashes and garbage results even for reads, and additionally wholesale data, stack corruption and/or security vulnerabilities for writes.

When do those pointers get invalidated?

If you call some string member function that modifies the string or reserves further capacity, any pointer values returned beforehand by any of the above methods are invalidated. You can use those methods again to get another pointer. (The rules are the same as for iterators into strings).

See also How to get a character pointer valid even after x leaves scope or is modified further below....

So, which is better to use?

From C++11, use .c_str() for ASCIIZ data, and .data() for "binary" data (explained further below).

In C++03, use .c_str() unless certain that .data() is adequate, and prefer .data() over &x[0] as it's safe for empty strings....

...try to understand the program enough to use data() when appropriate, or you'll probably make other mistakes...

The ASCII NUL '\0' character guaranteed by .c_str() is used by many functions as a sentinel value denoting the end of relevant and safe-to-access data. This applies to both C++-only functions like say fstream::fstream(const char* filename, ...) and shared-with-C functions like strchr(), and printf().

Given C++03's .c_str()'s guarantees about the returned buffer are a super-set of .data()'s, you can always safely use .c_str(), but people sometimes don't because:

• using .data() communicates to other programmers reading the source code that the data is not ASCIIZ (rather, you're using the string to store a block of data (which sometimes isn't even really textual)), or that you're passing it to another function that treats it as a block of "binary" data. This can be a crucial insight in ensuring that other programmers' code changes continue to handle the data properly.
• C++03 only: there's a slight chance that your string implementation will need to do some extra memory allocation and/or data copying in order to prepare the NUL terminated buffer

As a further hint, if a function's parameters require the (const) char* but don't insist on getting x.size(), the function probably needs an ASCIIZ input, so .c_str() is a good choice (the function needs to know where the text terminates somehow, so if it's not a separate parameter it can only be a convention like a length-prefix or sentinel or some fixed expected length).

How to get a character pointer valid even after x leaves scope or is modified further

You'll need to copy the contents of the string x to a new memory area outside x. This external buffer could be in many places such as another string or character array variable, it may or may not have a different lifetime than x due to being in a different scope (e.g. namespace, global, static, heap, shared memory, memory mapped file).

To copy the text from std::string x into an independent character array:

// USING ANOTHER STRING - AUTO MEMORY MANAGEMENT, EXCEPTION SAFE
std::string old_x = x;
// - old_x will not be affected by subsequent modifications to x...
// - you can use `&old_x[0]` to get a writable char* to old_x's textual content
// - you can use resize() to reduce/expand the string
//   - resizing isn't possible from within a function passed only the char* address

std::string old_x = x.c_str(); // old_x will terminate early if x embeds NUL
// Copies ASCIIZ data but could be less efficient as it needs to scan memory to
// find the NUL terminator indicating string length before allocating that amount
// of memory to copy into, or more efficient if it ends up allocating/copying a
// lot less content.
// Example, x == "ab\0cd" -> old_x == "ab".

// USING A VECTOR OF CHAR - AUTO, EXCEPTION SAFE, HINTS AT BINARY CONTENT, GUARANTEED CONTIGUOUS EVEN IN C++03
std::vector<char> old_x(x.data(), x.data() + x.size());       // without the NUL
std::vector<char> old_x(x.c_str(), x.c_str() + x.size() + 1);  // with the NUL

// USING STACK WHERE MAXIMUM SIZE OF x IS KNOWN TO BE COMPILE-TIME CONSTANT "N"
// (a bit dangerous, as "known" things are sometimes wrong and often become wrong)
char y[N + 1];
strcpy(y, x.c_str());

// USING STACK WHERE UNEXPECTEDLY LONG x IS TRUNCATED (e.g. Hello\0->Hel\0)
char y[N + 1];
strncpy(y, x.c_str(), N);  // copy at most N, zero-padding if shorter
y[N] = '\0';               // ensure NUL terminated

// USING THE STACK TO HANDLE x OF UNKNOWN (BUT SANE) LENGTH
char* y = alloca(x.size() + 1);
strcpy(y, x.c_str());

// USING THE STACK TO HANDLE x OF UNKNOWN LENGTH (NON-STANDARD GCC EXTENSION)
char y[x.size() + 1];
strcpy(y, x.c_str());

// USING new/delete HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = new char[x.size() + 1];
strcpy(y, x.c_str());
//     or as a one-liner: char* y = strcpy(new char[x.size() + 1], x.c_str());
// use y...
delete[] y; // make sure no break, return, throw or branching bypasses this

// USING new/delete HEAP MEMORY, SMART POINTER DEALLOCATION, EXCEPTION SAFE
// see boost shared_array usage in Johannes Schaub's answer

// USING malloc/free HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = strdup(x.c_str());
// use y...
free(y);

Other reasons to want a char* or const char* generated from a string

So, above you've seen how to get a (const) char*, and how to make a copy of the text independent of the original string, but what can you do with it? A random smattering of examples...

• give "C" code access to the C++ string's text, as in printf("x is '%s'", x.c_str());
• copy x's text to a buffer specified by your function's caller (e.g. strncpy(callers_buffer, callers_buffer_size, x.c_str())), or volatile memory used for device I/O (e.g. for (const char* p = x.c_str(); *p; ++p) *p_device = *p;)
• append x's text to an character array already containing some ASCIIZ text (e.g. strcat(other_buffer, x.c_str())) - be careful not to overrun the buffer (in many situations you may need to use strncat)
• return a const char* or char* from a function (perhaps for historical reasons - client's using your existing API - or for C compatibility you don't want to return a std::string, but do want to copy your string's data somewhere for the caller)
  • be careful not to return a pointer that may be dereferenced by the caller after a local string variable to which that pointer pointed has left scope
  • some projects with shared objects compiled/linked for different std::string implementations (e.g. STLport and compiler-native) may pass data as ASCIIZ to avoid conflicts

Setting margins on table cells doesn't really have any effect as far as I know. The true CSS equivalent for cellspacing is border-spacing - but it doesn't work in Internet Explorer.

You can use border-collapse: collapse to reliably set cell spacing to 0 as mentioned, but for any other value I think the only cross-browser way is to keep using the cellspacing attribute.

Read the Advanced Bash-Scripting Guide Chapter 19. Here Documents.

Here's an example which will write the contents to a file at /tmp/yourfilehere

cat << EOF > /tmp/yourfilehere
These contents will be written to the file.
        This line is indented.
EOF

Note that the final 'EOF' (The LimitString) should not have any whitespace in front of the word, because it means that the LimitString will not be recognized.

In a shell script, you may want to use indentation to make the code readable, however this can have the undesirable effect of indenting the text within your here document. In this case, use <<- (followed by a dash) to disable leading tabs (Note that to test this you will need to replace the leading whitespace with a tab character, since I cannot print actual tab characters here.)

#!/usr/bin/env bash

if true ; then
    cat <<- EOF > /tmp/yourfilehere
    The leading tab is ignored.
    EOF
fi

If you don't want to interpret variables in the text, then use single quotes:

cat << 'EOF' > /tmp/yourfilehere
The variable $FOO will not be interpreted.
EOF

To pipe the heredoc through a command pipeline:

cat <<'EOF' |  sed 's/a/b/'
foo
bar
baz
EOF

Output:

foo
bbr
bbz

... or to write the the heredoc to a file using sudo:

cat <<'EOF' |  sed 's/a/b/' | sudo tee /etc/config_file.conf
foo
bar
baz
EOF

This is easy with a flexbox:

#wrapper {_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
#left {_x000D_
  flex: 0 0 65%;_x000D_
}_x000D_
_x000D_
#right {_x000D_
  flex: 1;_x000D_
}

<div id="wrapper">_x000D_
  <div id="left">Left side div</div>_x000D_
  <div id="right">Right side div</div>_x000D_
</div>

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

You cannot. The column order is just a "cosmetic" thing we humans care about - to SQL Server, it's almost always absolutely irrelevant.

What SQL Server Management Studio does in the background when you change column order there is recreating the table from scratch with a new CREATE TABLE command, copying over the data from the old table, and then dropping it.

There is no SQL command to define the column ordering.

Okay, I'd like to just add my class only because there might be some dev out there in the future that wants to connect to a Netbackup server (or something similar) and do stuff from Java while ignoring the SSL cert. This worked for me and we use windows active directory for auth to the Netbackup server.

    SSLContext sslcontext = null;

}

I know it can be considered off-topic, but I bet the dev that tries to connect to a Netbackup server will probably end up here. By the way many thanks to all the answers in this question! The spec I'm talking about is here and their code samples are (currently) missing a Java example.

***This is of course unsafe since we ignore the cert!

Technically, to repair your statement, you can add LIMIT 1 to the subquery to ensure that at most 1 row is returned. That would remove the error, your code would still be nonsense.

... 'SELECT store_key FROM store LIMIT 1' ...

Practically, you want to match rows somehow instead of picking an arbitrary row from the remote table store to update every row of your local table customer.
Your rudimentary question doesn't provide enough details, so I am assuming a text column match_name in both tables (and UNIQUE in store) for the sake of this example:

... 'SELECT store_key FROM store
     WHERE match_name = ' || quote_literal(customer.match_name)  ...

But that's an extremely expensive way of doing things.

Ideally, you should completely rewrite the statement.

UPDATE customer c
SET    customer_id = s.store_key
FROM   dblink('port=5432, dbname=SERVER1 user=postgres password=309245'
             ,'SELECT match_name, store_key FROM store')
       AS s(match_name text, store_key integer)
WHERE c.match_name = s.match_name
AND   c.customer_id IS DISTINCT FROM s.store_key;

This remedies a number of problems in your original statement.

• Obviously, the basic problem leading to your error is fixed.

• It's almost always better to join in additional relations in the FROM clause of an UPDATE statement than to run correlated subqueries for every individual row.

• When using dblink, the above becomes a thousand times more important. You do not want to call dblink() for every single row, that's extremely expensive. Call it once to retrieve all rows you need.

• With correlated subqueries, if no row is found in the subquery, the column gets updated to NULL, which is almost always not what you want.
  In my updated form, the row only gets updated if a matching row is found. Else, the row is not touched.

• Normally, you wouldn't want to update rows, when nothing actually changes. That's expensively doing nothing (but still produces dead rows). The last expression in the WHERE clause prevents such empty updates:

   AND   c.customer_id IS DISTINCT FROM sub.store_key
  

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

Okay, I assume you using php7.2 (or higher) on Ubuntu 16 or higher

if none of this worked, you must know nginx-fastCGI uses different pid and .sock for different sites hosted on the same server.

To troubleshoot 'No input file specified' problem, you must tell the nginx yoursite.conf file which one of the sock file to use.

1. Uncomment the default fastcgi_pass unix:/var/run/php7.2-fpm.sock Make sure you have the following directives in place on the conf file,

   location / {
       try_files $uri $uri/ /index.php$is_args$args;
   }
   location ~ \.php$ {
           try_files $uri /index.php =404;
           #fastcgi_pass unix:/var/run/php7.2-fpm.sock;
           fastcgi_pass unix:/var/php-nginx/158521651519246.sock/socket;
           fastcgi_index index.php;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           include fastcgi_params;
   }
   

2. have a look at the list of sock and pid files using ls -la /var/php-nginx/(if you have recently added the file, it should be the last one on the list)

3.copy the filename of the .sock file (usually a 15 digit number) and paste it to your location ~ \.php directive

fastcgi_pass unix:/var/php-nginx/{15digitNumber}.sock/socket;

and restart nginx. Let me know if it worked.

ints are value types; they can never be null. Instead, if the parsing failed, parseInt will throw a NumberFormatException that you need to catch.

You can add

DBQuery.prototype._prettyShell = true

to your file in $HOME/.mongorc.js to enable pretty print globally by default.

The first is a list, the second is a tuple. Lists are mutable, tuples are not.

Take a look at the Data Structures section of the tutorial, and the Sequence Types section of the documentation.

Angularjs ui bootstrap you can use angularjs ui bootstrap, it provides date validation also

<input type="text"  class="form-control"

in controller can specify whatever format you want to display the date as datefilter

$scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];

Its a late answer, but as I can see most of the people mentioned about "refresh" method to redirect a webpage. As per W3C, we should not use "refresh" to redirect. Because it could break the "back" button. Imagine that the user presses the "back" button, the refresh would work again, and the user would bounce forward. The user will most likely get very annoyed, and close the window, which is probably not what you, as the author of this page, want.

Use HTTP redirects instead. One can refer the complete documentation here: W3C document

This problem can occur if you have altogether too much stuff being started when the server is started -- or if you are in debug mode and stepping through the initialization sequence. In eclipse, changing the start-timeout by 'opening' the tomcat server entry 'Servers view' tab of the Debug Perspective is convenient. In some situations it is useful to know where this setting is 'really' stored.

Tomcat reads this setting from the element in the element in the servers.xml file. This file is stored in the .metatdata/.plugins/org.eclipse.wst.server.core directory of your eclipse workspace, ie:

//.metadata/.plugins/org.eclipse.wst.server.core/servers.xml

There are other juicy configuration files for Eclipse plugins in other directories under .metadata/.plugins as well.

Here's an example of the servers.xml file, which is what is changed when you edit the tomcat server configuration through the Eclipse GUI:

Note the 'start-timeout' property that is set to a good long 1200 seconds above.

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

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

Add this to your head:

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

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

And your form may still look something like:

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

This works , this is my case ...

Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.

SSLContextBuilder sslcontextbuilder = SSLContexts.custom();

sslcontextbuilder.loadTrustMaterial(
            new File("C:\\path to\\truststore.jks"), //path to jks file
            "password".toCharArray(), //enters in the truststore password for use
            new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
            );

SSLContext sslcontext = sslcontextbuilder.build(); //load trust store

SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory 



try { 
        HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert

        System.out.println("Executing request " + httpget.getRequestLine());

        CloseableHttpResponse response = httpclient.execute(httpget);
        try {
            HttpEntity entity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());

            EntityUtils.consume(entity);
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

if you want to disable the scrollbar, but still able to scroll the content of inner DIV, use below code in css,

.divHideScroll::-webkit-scrollbar {
    width: 0 !important
}
.divHideScroll {
    overflow: -moz-scrollbars-none;
}
.divHideScroll {
    -ms-overflow-style: none;
}

divHideScroll is the class name of the target div.

It will work in all major browser (Chrome, Safari, Mozilla, Opera, and IE)

Why not check if for nothing?

if not inputbox("bleh") = nothing then
'Code
else
' Error
end if

This is what i typically use, because its a little easier to read.

if you have any problem with the library you can use Microsoft.Data.Sqlite;

 public static DataTable GetData(string connectionString, string query)
        {
            DataTable dt = new DataTable();
            Microsoft.Data.Sqlite.SqliteConnection connection;
            Microsoft.Data.Sqlite.SqliteCommand command;

            connection = new Microsoft.Data.Sqlite.SqliteConnection("Data Source= YOU_PATH_BD.sqlite");
            try
            {
                connection.Open();
                command = new Microsoft.Data.Sqlite.SqliteCommand(query, connection);
                dt.Load(command.ExecuteReader());
                connection.Close();
            }
            catch
            {
            }

            return dt;
        }

you can add NuGet Package Microsoft.Data.Sqlite

        Dim aDate As DateTime = #3/1/2008# 'sample date
    Dim StartDate As DateTime = aDate.AddMonths(-1).AddDays(-(aDate.Day - 1))
    Dim EndDate As DateTime = StartDate.AddDays(DateTime.DaysInMonth(StartDate.Year, StartDate.Month) - 1)

    'to access just the date portion
    ' StartDate.Date
    ' EndDate.Date

If you have multiple rows for parent_id.

SELECT GROUP_CONCAT(id) FROM table_level where parent_id=4 GROUP BY parent_id;

If you want to replace space with comma.

SELECT REPLACE(id,' ',',') FROM table_level where parent_id=4;

You can use

moment().isSameOrBefore(Moment|String|Number|Date|Array);
moment().isSameOrAfter(Moment|String|Number|Date|Array);

or

moment().isBetween(moment-like, moment-like);

See here : http://momentjs.com/docs/#/query/

It should be something like...

<xsl:if test="contains($hhref, '1234')">

(not tested)

See w3schools (always a good reference BTW)

URLs are defined in RFC 3986, though other RFCs are relevant as well but RFC 1738 is obsolete.

They may not have spaces in them, along with many other characters. Since those forbidden characters often need to be represented somehow, there is a scheme for encoding them into a URL by translating them to their ASCII hexadecimal equivalent with a "%" prefix.

Most programming languages/platforms provide functions for encoding and decoding URLs, though they may not properly adhere to the RFC standards. For example, I know that PHP does not.

according to documentation:

10.0.2.2 - Special alias to your host loopback interface (i.e., 127.0.0.1 on your development machine)

check Emulator Networking for more tricks on emulator networking.

Partition the table monthly.That is the best way to handle tables with large daily influx ,be it oracle or MSSQL.

I just wanted to add an additional option: In your input add the form tag and specify the name of a form that doesn't exist on your page:

<input form="fakeForm" type="text" readonly value="random value" />

One of the most easy ways to find where the app is within the simulator. User "NSTemporaryDirectory()"

Steps-

1. Apply breakpoint anywhere within the app and run the app.

2. When the app stops at the breakpoint, type following command in Xcode console.

   po NSTemporaryDirectory()

See the below image for a proper insight

Now you have the exact path upto temporary folder. You can go back and see all app related folders.

Hope this also helps. Happy Coding :)

SQLExplorer is a great Eclipse plugin or standalone interface that works with many different database systems, either with dedicated drivers or with ODBC.

The canonical solution in the standard library is argparse (docs):

Here is an example:

from argparse import ArgumentParser

parser = ArgumentParser()
parser.add_argument("-f", "--file", dest="filename",
                    help="write report to FILE", metavar="FILE")
parser.add_argument("-q", "--quiet",
                    action="store_false", dest="verbose", default=True,
                    help="don't print status messages to stdout")

args = parser.parse_args()

argparse supports (among other things):

• Multiple options in any order.
• Short and long options.
• Default values.
• Generation of a usage help message.

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

the return statement exits from the current function and exit() exits from the program

they are the same when used in main() function

also return is a statement while exit() is a function which requires stdlb.h header file

None of the above answers worked for me. I was going crazy until I found this solution below!

Simply run:

sudo apt install python-opencv

@Html.LabelFor(model => model.SomekingStatus, "foo bar")

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

Press app --> Edit Configurations
After that change value in Launch on "Nothing"

For simple types you can use "IndexOf" :

List<string> arr = new List<string>();
arr.Add("aaa");
arr.Add("bbb");
arr.Add("ccc");
int i = arr.IndexOf("bbb"); // RETURNS 1.

As others already replied, it's late to write unit tests, but not too late. The question is whether your code is testable or not. Indeed, it's not easy to put existing code under test, there is even a book about this: Working Effectively with Legacy Code (see key points or precursor PDF).

Now writing the unit tests or not is your call. You just need to be aware that it could be a tedious task. You might tackle this to learn unit-testing or consider writing acceptance (end-to-end) tests first, and start writing unit tests when you'll change the code or add new feature to the project.

You could fill the C Column with variations on the following formula:

=IF(ISERROR(MATCH(A1,$B:$B,0)),"",A1)

Then C would only contain values that were in A and C.

Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>

This is crazily stupid, but if you use the code:

fprintf("%x", variable)

and you use the -Wall flag while compiling, then gcc will kick out a warning of that it expects an argument of 'unsigned int' while the argument is of type '____'. (If this warning doesn't appear, then your variable is of type 'unsigned int'.)

Best of luck!

Edit: As was brought up below, this only applies to compile time. Very helpful when trying to figure out why your pointers aren't behaving, but not very useful if needed during run time.

Just for fun I thought I'd knock it up. It ended up being trickier than I thought because I went in not fully understanding how the boundary part works, eventually I worked out that the starting and ending '--' were significant and off it went.

<?php
    if(isset($_POST['submit']))
    {
        //The form has been submitted, prep a nice thank you message
        $output = '<h1>Thanks for your file and message!</h1>';
        //Set the form flag to no display (cheap way!)
        $flags = 'style="display:none;"';

        //Deal with the email
        $to = '[email protected]';
        $subject = 'a file for you';

        $message = strip_tags($_POST['message']);
        $attachment = chunk_split(base64_encode(file_get_contents($_FILES['file']['tmp_name'])));
        $filename = $_FILES['file']['name'];

        $boundary =md5(date('r', time())); 

        $headers = "From: [email protected]\r\nReply-To: [email protected]";
        $headers .= "\r\nMIME-Version: 1.0\r\nContent-Type: multipart/mixed; boundary=\"_1_$boundary\"";

        $message="This is a multi-part message in MIME format.

--_1_$boundary
Content-Type: application/octet-stream; name=\"$filename\" 
Content-Transfer-Encoding: base64 
Content-Disposition: attachment 

$attachment

        mail($to, $subject, $message, $headers);
    }
?>

<p><input type="submit" name="submit" id="submit" value="send"></p>
</form>
</body>
</html>

Very barebones really, and obviously the using inline CSS to hide the form is a bit cheap and you'd almost certainly want a bit more feedback to the user! Also, I'd probably spend a bit more time working out what the actual Content-Type for the file is, rather than cheating and using application/octet-stream but that part is quite as interesting.

In which scenarios does one out-perform the other?

For smaller tables (less than 1000 rows) use a temp variable, otherwise use a temp table.

Actually this is not a duplicate question. And this how i solve my problem after several times :

   int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());

This is the way to get offset from desired timezone.

Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.

   DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
                         DateTimeZone.forID("anytimezone"));

Now we will add our offset to the datetime, and get the timestamp from it.

    dt = dt.plusMillis(offset);
    Timestamp ts = new Timestamp(dt.getMillis());

May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.

We released a new library: PySimpleSOAP, that provides support for simple and functional client/server. It goals are: ease of use and flexibility (no classes, autogenerated code or xml is required), WSDL introspection and generation, WS-I standard compliance, compatibility (including Java AXIS, .NET and Jboss WS). It is included into Web2Py to enable full-stack solutions (complementing other supported protocols such as XML_RPC, JSON, AMF-RPC, etc.).

If someone is learning SOAP or want to investigate it, I think it is a good choice to start.

A simple way of doing is to press Ctrl + Shift + C, on the lines of your code.

For comment and for uncomment do same .. :)

Use SHOW CREATE TABLE your-table-name to see what column is your primary key.

Use the vlookup function.

Put both sets of data in the same excel file, on different sheets. Then, in the column next to the 805 row set (which I assume is on sheet2), enter

=if(isna(vlookup(A1, Sheet1!$A$1:$A$800, 1, false)), 0, 1)

The column will contain 0 for values that are not found in the other sheet, and 1 for values that are. You can sort the sheet to find all the missing values.

I've experienced the same problem. The thing is that I forgot to start the apache and mysql in xampp... :S

Instead of launching the batch directly from explorer - create a shortcut to the batch and set the starting directory in the properties of the shortcut to a local path like %TEMP% or something.

To delete the symbolic link, use the rmdir command.

You can use not(expression) function

not() is a function in xpath (as opposed to an operator)

Example:

//a[not(contains(@id, 'xx'))]

OR

expression != true()

Try this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
     fillButton[i].setBackground(getBaseContext().getResources().getDrawable(R.drawable.drawable_name));
}
else {
    fillButton[i].setBackgroundColor(Color.argb(255,193,234,203));
}

$date=date("Y-m-d");
echo"$date";
echo"<br>SELECT DATE: <input type='date'  name='date'  id='datepicker' 
value='$date' required >";

If you want a permanent solution for wordwrapping lines, go to menu File → Preference → Settings and change editor.wordWrap: "on". This will apply always.

However, we usually keep changing our preference to check code. So, I use the Alt + Z key to wrap written code of a file or you can go to menu View → Toggle Word Wrap. This applies whenever you want not always. And again Alt + Z to undo wordwrap (will show the full line in one line).

I just changed project facet to 1.7 and it worked.

The issue here is that you've opened a file and read its contents so the cursor is at the end of the file. By writing to the same file handle, you're essentially appending to the file.

The easiest solution would be to close the file after you've read it in, then reopen it for writing.

with open("replayScript.json", "r") as jsonFile:
    data = json.load(jsonFile)

data["location"] = "NewPath"

with open("replayScript.json", "w") as jsonFile:
    json.dump(data, jsonFile)

Alternatively, you can use seek() to move the cursor back to the beginning of the file then start writing, followed by a truncate() to deal with the case where the new data is smaller than the previous.

with open("replayScript.json", "r+") as jsonFile:
    data = json.load(jsonFile)

    data["location"] = "NewPath"

    jsonFile.seek(0)  # rewind
    json.dump(data, jsonFile)
    jsonFile.truncate()

To filter a list of dicts you can use the selectattr filter together with the equalto test:

network.addresses.private_man | selectattr("type", "equalto", "fixed")

The above requires Jinja2 v2.8 or later (regardless of Ansible version).

Ansible also has the tests match and search, which take regular expressions:

match will require a complete match in the string, while search will require a match inside of the string.

network.addresses.private_man | selectattr("type", "match", "^fixed$")

To reduce the list of dicts to a list of strings, so you only get a list of the addr fields, you can use the map filter:

... | map(attribute='addr') | list

Or if you want a comma separated string:

... | map(attribute='addr') | join(',')

Combined, it would look like this.

- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

If you already have a config.json file then the final file should look something like this... Here registry.myprivate.com is the one which was giving me problems.

{ "auths": { "https://index.docker.io/v1/": { "auth": "xxxxxxxxxxxxxxxxxxxx==" }, "registry.myprivate.com": { "auth": "xxxxxxxxxxxxxxxxxxxx=" } }, "HttpHeaders": { "User-Agent": "Docker-Client/19.03.8 (linux)" }, "insecure-registries" : ["registry.myprivate.com"] }

For just in case someone need it i made and use the following static class in my projects

Usage example:

if (!ModelState.IsValid)
{
    var errors = ModelState.GetModelErrors();
    return Json(new { errors });
}

Usings:

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Mvc;
using WebGrease.Css.Extensions;

Class:

public static class ModelStateErrorHandler
{
    /// <summary>
    /// Returns a Key/Value pair with all the errors in the model
    /// according to the data annotation properties.
    /// </summary>
    /// <param name="errDictionary"></param>
    /// <returns>
    /// Key: Name of the property
    /// Value: The error message returned from data annotation
    /// </returns>
    public static Dictionary<string, string> GetModelErrors(this ModelStateDictionary errDictionary)
    {
        var errors = new Dictionary<string, string>();
        errDictionary.Where(k => k.Value.Errors.Count > 0).ForEach(i =>
        {
            var er = string.Join(", ", i.Value.Errors.Select(e => e.ErrorMessage).ToArray());
            errors.Add(i.Key, er);
        });
        return errors;
    }

    public static string StringifyModelErrors(this ModelStateDictionary errDictionary)
    {
        var errorsBuilder = new StringBuilder();
        var errors = errDictionary.GetModelErrors();
        errors.ForEach(key => errorsBuilder.AppendFormat("{0}: {1} -", key.Key,key.Value));
        return errorsBuilder.ToString();
    }
}

Building on a previous answer by @user1172173 that addressed SQL Injection vulnerabilities, see below:

CREATE PROCEDURE [dbo].[spQ_SomeColumnByCustomerId](
@CustomerId int,
@SchemaName varchar(20),
@TableName nvarchar(200)) AS
SET Nocount ON
DECLARE @SQLQuery AS NVARCHAR(500)
DECLARE @ParameterDefinition AS NVARCHAR(100)
DECLARE @Table_ObjectId int;
DECLARE @Schema_ObjectId int;
DECLARE @Schema_Table_SecuredFromSqlInjection NVARCHAR(125)

SET @Table_ObjectId = OBJECT_ID(@TableName)
SET @Schema_ObjectId = SCHEMA_ID(@SchemaName)
SET @Schema_Table_SecuredFromSqlInjection = SCHEMA_NAME(@Schema_ObjectId) + '.' + OBJECT_NAME(@Table_ObjectId)

SET @SQLQuery = N'SELECT TOP 1 ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn 
FROM dbo.Customer 
INNER JOIN ' + @Schema_Table_SecuredFromSqlInjection + ' 
ON dbo.Customer.Customerid = ' + @Schema_Table_SecuredFromSqlInjection + '.CustomerId 
WHERE dbo.Customer.CustomerID = @CustomerIdParam 
ORDER BY ' + @Schema_Table_SecuredFromSqlInjection + '.SomeColumn DESC' 
SET @ParameterDefinition =  N'@CustomerIdParam INT'

EXECUTE sp_executesql @SQLQuery, @ParameterDefinition, @CustomerIdParam = @CustomerId; RETURN

Waking up an old thread here I see, but I felt the urge to add the "new" .xlsx format.

According to http://filext.com/file-extension/XLSX the extension for .xlsx is application/vnd.openxmlformats-officedocument.spreadsheetml.sheet. It might be a good idea to include it when checking for mime types!

A couple of distinctions that weren't touched on here:

• With exec(), you can pass an optional param variable which will receive an array of output lines. In some cases this might save time, especially if the output of the commands is already tabular.

Compare:

exec('ls', $out);
var_dump($out);
// Look an array

$out = shell_exec('ls');
var_dump($out);
// Look -- a string with newlines in it

Conversely, if the output of the command is xml or json, then having each line as part of an array is not what you want, as you'll need to post-process the input into some other form, so in that case use shell_exec.

It's also worth pointing out that shell_exec is an alias for the backtic operator, for those used to *nix.

$out = `ls`;
var_dump($out);

exec also supports an additional parameter that will provide the return code from the executed command:

exec('ls', $out, $status);
if (0 === $status) {
    var_dump($out);
} else {
    echo "Command failed with status: $status";
}

As noted in the shell_exec manual page, when you actually require a return code from the command being executed, you have no choice but to use exec.

I've had to do this a few times to-date. Note that this only works on 1 file at a time.

1. Get a list of all commits that modified a file. The one at the bottom will the the first commit:

   git log --pretty=oneline --branches -- pathToFile

2. To remove the file from history use the first commit sha1 and the path to file from the previous command, and fill them into this command:

   git filter-branch --index-filter 'git rm --cached --ignore-unmatch <path-to-file>' -- <sha1-where-the-file-was-first-added>..

STEP 1: cd /opt/google/chrome

STEP 2: edit google-chrome file. gedit google-chrome

STEP 3: find this line: exec -a "$0" "$HERE/chrome" "$@".

Mostly this line is in the end of google-chrome file.

Comment it out like this : #exec -a "$0" "$HERE/chrome" "$@"

STEP 4:add a new line at the same place.

exec -a "$0" "$HERE/chrome" "$@" --user-data-dir

STEP 5: save google-chrome file and quit. And then you can use chrome as root user. Enjoy it!

That is because you pass string to the function. Just remove quotes and pass real values:

<a href=# onclick="return ReAssign(valuationId, user)">Re-Assign</a>

Guess the ReAssign function should return true or false.

.nav ul li a#nav-ask{
    display:none;
}

A submodule is its own repo/work-area, with its own .git directory.

So, first commit/push your submodule's changes:

$ cd path/to/submodule
$ git add <stuff>
$ git commit -m "comment"
$ git push

Then, update your main project to track the updated version of the submodule:

$ cd /main/project
$ git add path/to/submodule
$ git commit -m "updated my submodule"
$ git push

More compact way to get the difference between two datetime objects and then convert the difference into seconds is shown below (Python 3x):

from datetime import datetime
        
time1 = datetime.strftime('18 01 2021', '%d %m %Y')
    
time2 = datetime.strftime('19 01 2021', '%d %m %Y')

difference = time2 - time1

difference_in_seconds = difference.total_seconds()

Change 'middle' to 'center'. Like so:

<img align="center" ....>

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last else "" }}

Issues

blak3r / Rushyo's solution works fine for everything except Windows 8. Running AT on Windows 8 results in:

The AT command has been deprecated. Please use schtasks.exe instead.

The request is not supported.

(see screenshot #1) and will return %errorLevel% 1.

Research

So, I went searching for other commands that require elevated permissions. rationallyparanoid.com had a list of a few, so I ran each command on the two opposite extremes of current Windows OSs (XP and 8) in the hopes of finding a command that would be denied access on both OSs when run with standard permissions.

Eventually, I did find one - NET SESSION. A true, clean, universal solution that doesn't involve:

• the creation of or interaction with data in secure locations
• analyzing data returned from FOR loops
• searching strings for "Administrator"
• using AT (Windows 8 incompatible) or WHOAMI (Windows XP incompatible).

Each of which have their own security, usability, and portability issues.

Testing

I've independently confirmed that this works on:

• Windows XP, x86
• Windows XP, x64
• Windows Vista, x86
• Windows Vista, x64
• Windows 7, x86
• Windows 7, x64
• Windows 8, x86
• Windows 8, x64
• Windows 10 v1909, x64

(see screenshot #2)

Implementation / Usage

So, to use this solution, simply do something like this:

@echo off

Explanation

NET SESSION is a standard command used to "manage server computer connections. Used without parameters, [it] displays information about all sessions with the local computer."

So, here's the basic process of my given implementation:

1. @echo off
   • Disable displaying of commands
2. goto check_Permissions
   • Jump to the :check_Permissions code block
3. net session >nul 2>&1
   • Run command
   • Hide visual output of command by
     1. Redirecting the standard output (numeric handle 1 / STDOUT) stream to nul
     2. Redirecting the standard error output stream (numeric handle 2 / STDERR) to the same destination as numeric handle 1
4. if %errorLevel% == 0
   • If the value of the exit code (%errorLevel%) is 0 then this means that no errors have occurred and, therefore, the immediate previous command ran successfully
5. else
   • If the value of the exit code (%errorLevel%) is not 0 then this means that errors have occurred and, therefore, the immediate previous command ran unsuccessfully
6. The code between the respective parenthesis will be executed depending on which criteria is met

Thank you, @Tilka, for changing your accepted answer to mine. :)

Setting links on the page woud require a combination of @Ravi and @ncksllvn's answers:

// Find link in $(".product-item") and set "target" attribute to "_blank".
$(this).find("a").attr("target", "_blank");

For opening the page in another window, see this question: jQuery click _blank And see this reference for window.open options for customization.

Update:

You would need something along:

$(document).ready(function() {
  $(".product-item").click(function() {
    var productLink = $(this).find("a");

    productLink.attr("target", "_blank");
    window.open(productLink.attr("href"));

    return false;
  });
});

Note the usage of .attr():

$element.attr("attribute_name")                   // Get value of attribute.
$element.attr("attribute_name", attribute_value)  // Set value of attribute.

#include<time.h> // for clock
#include<math.h> // for fmod
#include<cstdlib> //for system
#include <stdio.h> //for delay

using namespace std;

int main()
{


   clock_t t1,t2;

   t1=clock(); // first time capture

   // Now your time spanning loop or code goes here
   // i am first trying to display time elapsed every time loop runs

   int ddays=0; // d prefix is just to say that this variable will be used for display
   int dhh=0;
   int dmm=0;
   int dss=0;

   int loopcount = 1000 ; // just for demo your loop will be different of course

   for(float count=1;count<loopcount;count++)
   {

     t2=clock(); // we get the time now

     float difference= (((float)t2)-((float)t1)); // gives the time elapsed since t1 in milliseconds

    // now get the time elapsed in seconds

    float seconds = difference/1000; // float value of seconds
    if (seconds<(60*60*24)) // a day is not over
    {
        dss = fmod(seconds,60); // the remainder is seconds to be displayed
        float minutes= seconds/60;  // the total minutes in float
        dmm= fmod(minutes,60);  // the remainder are minutes to be displayed
        float hours= minutes/60; // the total hours in float
        dhh= hours;  // the hours to be displayed
        ddays=0;
    }
    else // we have reached the counting of days
    {
        float days = seconds/(24*60*60);
        ddays = (int)(days);
        float minutes= seconds/60;  // the total minutes in float
        dmm= fmod(minutes,60);  // the rmainder are minutes to be displayed
        float hours= minutes/60; // the total hours in float
        dhh= fmod (hours,24);  // the hours to be displayed

    }

    cout<<"Count Is : "<<count<<"Time Elapsed : "<<ddays<<" Days "<<dhh<<" hrs "<<dmm<<" mins "<<dss<<" secs";


    // the actual working code here,I have just put a delay function
    delay(1000);
    system("cls");

 } // end for loop

}// end of main 

The primary role of the @Named annotation is to define a bean for the purpose of resolving EL statements within the application, usually through JSF EL resolvers. Injection can be performed using names but this was not how injection in CDI was meant to work since CDI gives us a much richer way to express injection points and the beans to be injected into them.

Uncheck the "copy projects into workspace" checkbox, and then click "refresh" button, you will be able to import the project

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) 
    textView.setTextAppearance(R.style.yourStyle)

Swift 5 You can use a UIView extension so that you can add bottom border to any view:

extension UIView {

    func addBottomLine(width: CGFloat, color: UIColor) {
        let lineView: UIView = {
            let view = UIView()
            view.translatesAutoresizingMaskIntoConstraints = false
            view.backgroundColor = color
            return view
        }()
        addSubview(lineView)
        NSLayoutConstraint.activate([
            lineView.heightAnchor.constraint(equalToConstant: width),
            lineView.leadingAnchor.constraint(equalTo: leadingAnchor),
            lineView.trailingAnchor.constraint(equalTo: trailingAnchor),
            lineView.bottomAnchor.constraint(equalTo: bottomAnchor)
        ])
    }

}

You need to make the extension as .php to run a php code BUT if you can't change the extension you could use Ajax to run the php externally and get the result

For eg:

<html>
<head>
<script src="js/jquery.min.js"></script>
<script>
$(document).ready(function(){
   $.ajax({
        url:'php_File_with_php_code.php',
        type:'GET', 
        data:"parameter=some_parameter",
       success:function(data)
       {
              $("#thisdiv").html(data);
           }
    });
});
</script>
</head>
<body>
<div id="thisdiv"></div>
</body>
</html>

Here, the JQuery is loaded and as soon as the pages load, the ajax call a php file from where the data is taken, the data is then put in the div

Hope This Helps

You cannot directly copy a table into a destination server database from a different database if source db is not in your linked servers. But one way is possible that, generate scripts (schema with data) of the desired table into one table temporarily in the source server DB, then execute the script in the destination server DB to create a table with your data. Finally use INSERT INTO [DESTINATION_TABLE] select * from [TEMPORARY_SOURCE_TABLE]. After getting the data into your destination table drop the temporary one.

I found this solution when I faced the same situation. Hope this helps you too.

Please see if following solution works for you. The trick is to define a base processor interface which takes a base type of message.

interface IMessage
{
}

class LoginMessage : IMessage
{
}

class LogoutMessage : IMessage
{
}

class UnknownMessage : IMessage
{
}

interface IMessageProcessor
{
    void PrcessMessageBase(IMessage msg);
}

abstract class MessageProcessor<T> : IMessageProcessor where T : IMessage
{
    public void PrcessMessageBase(IMessage msg)
    {
        ProcessMessage((T)msg);
    }

    public abstract void ProcessMessage(T msg);

}

class LoginMessageProcessor : MessageProcessor<LoginMessage>
{
    public override void ProcessMessage(LoginMessage msg)
    {
        System.Console.WriteLine("Handled by LoginMsgProcessor");
    }
}

class LogoutMessageProcessor : MessageProcessor<LogoutMessage>
{
    public override void ProcessMessage(LogoutMessage msg)
    {
        System.Console.WriteLine("Handled by LogoutMsgProcessor");
    }
}

class MessageProcessorTest
{
    /// <summary>
    /// IMessage Type and the IMessageProcessor which would process that type.
    /// It can be further optimized by keeping IMessage type hashcode
    /// </summary>
    private Dictionary<Type, IMessageProcessor> msgProcessors = 
                                new Dictionary<Type, IMessageProcessor>();
    bool processorsLoaded = false;

    public void EnsureProcessorsLoaded()
    {
        if(!processorsLoaded)
        {
            var processors =
                from processorType in Assembly.GetExecutingAssembly().GetTypes()
                where processorType.IsClass && !processorType.IsAbstract &&
                      processorType.GetInterface(typeof(IMessageProcessor).Name) != null
                select Activator.CreateInstance(processorType);

            foreach (IMessageProcessor msgProcessor in processors)
            {
                MethodInfo processMethod = msgProcessor.GetType().GetMethod("ProcessMessage");
                msgProcessors.Add(processMethod.GetParameters()[0].ParameterType, msgProcessor);
            }

            processorsLoaded = true;
        }
    }

    public void ProcessMessages()
    {
        List<IMessage> msgList = new List<IMessage>();
        msgList.Add(new LoginMessage());
        msgList.Add(new LogoutMessage());
        msgList.Add(new UnknownMessage());

        foreach (IMessage msg in msgList)
        {
            ProcessMessage(msg);
        }
    }

    public void ProcessMessage(IMessage msg)
    {
        EnsureProcessorsLoaded();
        IMessageProcessor msgProcessor = null;
        if(msgProcessors.TryGetValue(msg.GetType(), out msgProcessor))
        {
            msgProcessor.PrcessMessageBase(msg);
        }
        else
        {
            System.Console.WriteLine("Processor not found");
        }
    }

    public static void Test()
    {
        new MessageProcessorTest().ProcessMessages();
    }
}

I copy the file "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5.1\Facades\system.runtime.dll" to bin folder of production server, this solve the problem.

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

Ubuntu 18.04.5 LTS (Bionic Beaver):

apt --reinstall install python3-debian
apt --reinstall install python3-six

If /usr/bin/chardet3 fails with error "ModuleNotFoundError: No module named 'pkg_resources'":

apt --reinstall install python3-pkg-resources

You can use argv npm module (install it by running npm install argv --save) for getting params in your webpack.config.js file and as for production you use -p flag "build": "webpack -p", you can add condition in webpack.config.js file like below

plugins: [
    new webpack.DefinePlugin({
        'process.env':{
            'NODE_ENV': argv.p ? JSON.stringify('production') : JSON.stringify('development')
        }
    })
]

And thats it.

A slightly more general solution based on join, that works even for pandas.Timestamp:

print("\n".join(map(str, my_list)))

The following seems to confirm that there are comparison operators for the DateTime class:

dev:~# php
<?php
date_default_timezone_set('Europe/London');

$d1 = new DateTime('2008-08-03 14:52:10');
$d2 = new DateTime('2008-01-03 11:11:10');
var_dump($d1 == $d2);
var_dump($d1 > $d2);
var_dump($d1 < $d2);
?>
bool(false)
bool(true)
bool(false)
dev:~# php -v
PHP 5.2.6-1+lenny3 with Suhosin-Patch 0.9.6.2 (cli) (built: Apr 26 2009 20:09:03)

Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
dev:~#

I would use this code. It includes an instancesOf function, and it runs through each number.

public class MathFunctions {

public static int mode(final int[] n) {
    int maxKey = 0;
    int maxCounts = 0;

    for (int i : n) {
        if (instancesOf(i, n) > maxCounts) {
            maxCounts = instancesOf(i, n);
            maxKey = i;
        }
    }

    return maxKey;
}

public static int instancesOf(int n, int[] Array) {
    int occurences = 0;
    for (int j : Array) {
        occurences += j == n ? 1 : 0;
    }
    return occurences;
}

public static void main (String[] args) {
    //TODO Auto-generated method stub
    System.out.println(mode(new int[] {100,200,2,300,300,300,500}));
}
}

I noticed that the code Gubatron posted doesn't work on my computer; it gave me an ArrayIndexOutOfBoundsException.

The best way to solve this is going to the AndroidManifest.xml: package="com.foocomp.fooapp:

• Set the cursor on "foocomp"
• Press Shift+F6
• Rename Package to whatever you want
• Repeat for "fooapp".

Works for me.

Also, replace in Path in Whole Project as it didn't change everything. Then Clean, Rebuild and it works --> In Android Studio / IntelliJ you should unmark "Compact Empty Middle Packages"

Root Cause

The JPA (Java persistence API) is a java specification for ORM (Object-Relational Mapping) tools. The spring-boot-starter-data-jpa dependency enables ORM in the context of the spring boot framework.

The JPA auto configuration feature of the spring boot application attempts to establish database connection using JPA Datasource. The JPA DataSource bean requires database driver to connect to a database.

The database driver should be available as a dependency in the pom.xml file. For the external databases such as Oracle, SQL Server, MySql, DB2, Postgres, MongoDB etc requires the database JDBC connection properties to establish the connection.

You need to configure the database driver and the JDBC connection properties to fix this exception Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured. Reason: Failed to determine a suitable driver class.

application.properties

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration 

application.yaml

spring:
autoconfigure:
    exclude:org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

By Programming

@SpringBootApplication(exclude =  {DataSourceAutoConfiguration.class })

I think @Evert has the right answer:

plt.scatter(dates,values)
plt.plot(dates, values)
plt.show()

Which is pretty much the same as

plt.plot(dates, values, '-o')
plt.show()

or whatever linestyle you prefer.

You probably need to open a command prompt with the PATH set up properly. Look for an icon in the start menu that says something like "Visual C++ 2005 Command Prompt". You should be able to run dumpbin (and all the other command line tools) from there.

I think the already provided solutions are overly verbose. A more concise way to do a frequency sorted barplot with ggplot is

ggplot(theTable, aes(x=reorder(Position, -table(Position)[Position]))) + geom_bar()

It's similar to what Alex Brown suggested, but a bit shorter and works without an anynymous function definition.

Update

I think my old solution was good at the time, but nowadays I'd rather use forcats::fct_infreq which is sorting factor levels by frequency:

require(forcats)

ggplot(theTable, aes(fct_infreq(Position))) + geom_bar()

Tuples are immutable and not supposed to be changed - that is what the list type is for. You could replace each tuple by originalTuple + (newElement,), thus creating a new tuple. For example:

t = (1,2,3)
t = t + (1,)
print t
(1,2,3,1)

But I'd rather suggest to go with lists from the beginning, because they are faster for inserting items.

And another hint: Do not overwrite the built-in name list in your program, rather call the variable l or some other name. If you overwrite the built-in name, you can't use it anymore in the current scope.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

If you want to know on which platform you are on out of "Linux", "Windows", or "Darwin" (Mac), without more precision, you should use:

>>> import platform
>>> platform.system()
'Linux'  # or 'Windows'/'Darwin'

The platform.system function uses uname internally.

The Differences in as easy as much possible: After having a basic understanding, the other comments posted above will be easier to catch.

Shell - "Shell" is a program, which facilitates the interaction between the user and the operating system (kernel). There are many shell implementation available, like sh, bash, csh, zsh...etc.

Using any of the Shell programs, we will be able to execute commands that are supported by that shell program.

Bash - It derived from Bourne-again Shell. Using this program, we will be able to execute all the commands specified by Shell. Also, we will be able to execute some commands that are specifically added to this program. Bash has backward compatibility with sh.

Sh - It derived from Bourne Shell. "sh" supports all the commands specified in the shell. Means, Using this program, we will be able to execute all the commands specified by Shell.

For more information, do: - https://man.cx/sh - https://man.cx/bash

I use the following command:

git checkout --track origin/other_remote_branch

When running a single test I usually do:

go test -run TestSomethingReallyCool ./folder1/folder2/ -v -count 1

-count 1 also ensures that the test is ran every time instead of being cached. Useful when you are testing against race conditions and have a test that fails only sometimes. In Go versions not using modules the same could be achieved by setting GOCACHE=off but this interacts poorly with Go modules.

I would put the secondSet in a HashMap before the comparison. This way you will reduce the second list's search time to n(1). Like this:

HashMap<Integer,Record> hm = new HashMap<Integer,Record>(secondSet.size());
int i = 0;
for(Record secondRecord : secondSet){
    hm.put(i,secondRecord);
    i++;
}
for(Record firstRecord : firstSet){
    for(int i=0; i<secondSet.size(); i++){
    //use hm for comparison
    }
}

If you're using SQL Server 2008, you can do this:

WHERE CONVERT(time(0), startHour) >= CONVERT(time(0), @startTime)

Here's a full test:

DECLARE @tbEvents TABLE (
    timeEvent   int      IDENTITY,
    startHour   datetime
)

INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 0, GETDATE())
INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 1, GETDATE())
INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 2, GETDATE())
INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 3, GETDATE())
INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 4, GETDATE())
INSERT INTO @tbEvents (startHour) SELECT DATEADD(hh, 5, GETDATE())

--SELECT * FROM @tbEvents

DECLARE @startTime  datetime

SET @startTime = DATEADD(mi, 65, GETDATE())

SELECT
    timeEvent,
    CONVERT(time(0), startHour)  AS 'startHour',
    CONVERT(time(0), @startTime) AS '@startTime'
FROM @tbEvents
WHERE CONVERT(time(0), startHour) >= CONVERT(time(0), @startTime)

Quick and in some cases error-prone solution:

Find Regexp: (?sm)(.*?)([^\n]*\b(class|interface|enum)\b.*)

Replace: $1/**\n * \n * @author <a href="mailto:[email protected]">John Smith</a>\n */\n$2

This will add the header to the first encountered class/interface/enum in the file. Class should have no existing header yet.

I know it's been a year since this was asked, but just for people that are going to visit this page I am posting my solution.

By using what @Aldi Unanto suggested here is a more complete answer:

  jQuery('.show_hide').click(function(e) {
    e.preventDefault();
    if (jQuery('.slidingDiv').is(":visible") ) {
      jQuery('.slidingDiv').stop(true,true).hide("slide", { direction: "left" }, 200);
    } else {
      jQuery('.slidingDiv').stop(true,true).show("slide", { direction: "left" }, 200);
    }
  });

First I prevent the link from doing anything on click. Then I add a check if the element is visible or not. When visible I hide it. When hidden I show it. You can change direction to left or right and duration from 200 ms to anything you like.

Edit: I have also added

.stop(true,true)

in order to clearQueue and jumpToEnd. Read about jQuery stop here

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;

import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

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

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

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }

}

It would depend on why you want it to restart itself.

If you are just looking for a way to have the service clean itself out periodically then you could have a timer running in the service that periodically causes a purge routine.

If you are looking for a way to restart on failure - the service host itself can provide that ability when it is setup.

So why do you need to restart the server? What are you trying to achieve?

To send an objective-c message in this instance you would do

[self score];

I suggest you read the Objective-C programming guide Objective-C Programming Guide

Another option is tcping.

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;

I use the "heredoc" syntax, which David Young mentions. But there is a catch:

#!/usr/bin/sh

mongo <db> <<EOF
db.<collection>.find({
  fieldName: { $exists: true }
})
.forEach( printjson );
EOF

The above will NOT work, because the phrase "$exists" will be seen by the shell and substituted with the value of the environment variable named "exists." Which, likely, doesn't exist, so after shell expansion, it becomes:

#!/usr/bin/sh

mongo <db> <<EOF
db.<collection>.find({
  fieldName: { : true }
})
.forEach( printjson );
EOF

In order to have it pass through you have two options. One is ugly, one is quite nice. First, the ugly one: escape the $ signs:

#!/usr/bin/sh

mongo <db> <<EOF
db.<collection>.find({
  fieldName: { \$exists: true }
})
.forEach( printjson );
EOF

I do NOT recommend this, because it is easy to forget to escape.

The other option is to escape the EOF, like this:

#!/usr/bin/sh

mongo <db> <<\EOF
db.<collection>.find({
  fieldName: { $exists: true }
})
.forEach( printjson );
EOF

Now, you can put all the dollar signs you want in your heredoc, and the dollar signs are ignored. The down side: That doesn't work if you need to put shell parameters/variables in your mongo script.

Another option you can play with is to mess with your shebang. For example,

#!/bin/env mongo
<some mongo stuff>

There are several problems with this solution:

1. It only works if you are trying to make a mongo shell script executable from the command line. You can't mix regular shell commands with mongo shell commands. And all you save by doing so is not having to type "mongo" on the command line... (reason enough, of course)

2. It functions exactly like "mongo <some-js-file>" which means it does not let you use the "use <db>" command.

I have tried adding the database name to the shebang, which you would think would work. Unfortunately, the way the system processes the shebang line, everything after the first space is passed as a single parameter (as if quoted) to the env command, and env fails to find and run it.

Instead, you have to embed the database change within the script itself, like so:

#!/bin/env mongo
db = db.getSiblingDB('<db>');
<your script>

As with anything in life, "there is more than one way to do it!"

public - can be access by anyone anywhere.
private - can only be accessed from with in the class it is a part of.
protected - can only be accessed from with in the class or any object that inherits off of the class.

Nothing is like null but in VB.
Static means you have one instance of that object, method for every instance of that class.

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

Details

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/

After a lot of trial and error i actually find the best, clearest and easiest multidimensional array on bash is to use a regular var. Yep.

Advantages: You don't have to loop through a big array, you can just echo "$var" and use grep/awk/sed. It's easy and clear and you can have as many columns as you like.

Example:

$ var=$(echo -e 'kris hansen oslo\nthomas jonson peru\nbibi abu johnsonville\njohnny lipp peru')

$ echo "$var"
kris hansen oslo
thomas johnson peru
bibi abu johnsonville
johnny lipp peru

If you want to find everyone in peru

$ echo "$var" | grep peru
thomas johnson peru
johnny lipp peru

Only grep(sed) in the third field

$ echo "$var" | sed -n -E '/(.+) (.+) peru/p'
thomas johnson peru
johnny lipp peru

If you only want x field

$ echo "$var" | awk '{print $2}'
hansen
johnson
abu
johnny

Everyone in peru that's called thomas and just return his lastname

$ echo "$var" |grep peru|grep thomas|awk '{print $2}'
johnson

Any query you can think of... supereasy.

To change an item:

$ var=$(echo "$var"|sed "s/thomas/pete/")

To delete a row that contains "x"

$ var=$(echo "$var"|sed "/thomas/d")

To change another field in the same row based on a value from another item

$ var=$(echo "$var"|sed -E "s/(thomas) (.+) (.+)/\1 test \3/")
$ echo "$var"
kris hansen oslo                                                                                                                                             
thomas test peru                                                                                                                                          
bibi abu johnsonville
johnny lipp peru

Of course looping works too if you want to do that

$ for i in "$var"; do echo "$i"; done
kris hansen oslo
thomas jonson peru
bibi abu johnsonville
johnny lipp peru

The only gotcha iv'e found with this is that you must always quote the var(in the example; both var and i) or things will look like this

$ for i in "$var"; do echo $i; done
kris hansen oslo thomas jonson peru bibi abu johnsonville johnny lipp peru

and someone will undoubtedly say it won't work if you have spaces in your input, however that can be fixed by using another delimeter in your input, eg(using an utf8 char now to emphasize that you can choose something your input won't contain, but you can choose whatever ofc):

$ var=$(echo -e 'field one?field two hello?field three yes moin\nfield 1?field 2?field 3 dsdds aq')

$ for i in "$var"; do echo "$i"; done
field one?field two hello?field three yes moin
field 1?field 2?field 3 dsdds aq

$ echo "$var" | awk -F '?' '{print $3}'
field three yes moin
field 3 dsdds aq

$ var=$(echo "$var"|sed -E "s/(field one)?(.+)?(.+)/\1?test?\3/")
$ echo "$var"
field one?test?field three yes moin
field 1?field 2?field 3 dsdds aq

If you want to store newlines in your input, you could convert the newline to something else before input and convert it back again on output(or don't use bash...). Enjoy!

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

while true ; do
    ...
    if [ something ]; then
        break
    fi
done

Try this

SELECT Count(*) AS N
FROM
(SELECT DISTINCT Name FROM table1) AS T;

Read this for more info.

RGB='#ffabcd';
A='0.5';
RGBA='('+parseInt(RGB.substring(1,3),16)+','+parseInt(RGB.substring(3,5),16)+','+parseInt(RGB.substring(5,7),16)+','+A+')';

I try to make it simple. You have two options while using Selenium 3+:

• Either upgrade your Firefox to 47.0.1 or higher and use the default geckodriver of Selenium3.

• Or disable using of geckodriver by specifying marionette to false and use the legacy Firefox driver. a simple command to run selenium is: java -Dwebdriver.firefox.marionette=false -jar selenium-server-standalone-3.0.1.jar. You can also disable using geckodriver from other commands that are mentioned in other answers.

To delete via SQL

Item.delete_all # accepts optional conditions

To delete by calling each model's destroy method (expensive but ensures callbacks are called)

Item.destroy_all # accepts optional conditions

All here

del statement does not delete an instance, it merely deletes a name.

When you do del i, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.

If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.

If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.

>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst     # memory is released

If you created some variables, you have to delete them all.

>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst     # memory release now

Building on @P-Lapointe solution, but making it extremely easy, you could use the maximum values from your data using max() and then you re-use those maximum values to set the legend xy coordinates. To make sure you don't get beyond the borders, you set up ylim slightly over the maximum values.

a=c(rnorm(1000))
b=c(rnorm(1000))
par(mfrow=c(1,2))
plot(a,ylim=c(0,max(a)+1))
legend(x=max(a)+0.5,legend="a",pch=1)
plot(a,b,ylim=c(0,max(b)+1),pch=2)
legend(x=max(b)-1.5,y=max(b)+1,legend="b",pch=2)

Your string has a non ascii character encoded in it.

Not being able to decode with utf-8 may happen if you've needed to use other encodings in your code. For example:

>>> 'my weird character \x96'.decode('utf-8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\encodings\utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x96 in position 19: invalid start byte

In this case, the encoding is windows-1252 so you have to do:

>>> 'my weird character \x96'.decode('windows-1252')
u'my weird character \u2013'

Now that you have Unicode, you can safely encode into utf-8.

If you want some icons (or all) from font-awesome including yout custom svg icons you can:

1- Go to http://fontawesome.io/ Download the zip and extract-it for example in your Desktop.

2- Go to http://fontastic.me/ use your email to create an account.

3- Once you have been logged-in click on the header option: Add More Icons.

4- Select the SVG of font-awesome located in your extracted zip inside fonts.

5- Repeat the procces uploading your own svg files.

6- Inside Home (at the header of the page) Select the icons you want to download, customize them to give your custom names and select publish to have a link or download the fonts and css.

Sorry about my english ! :D

Answer for the "new" and "cool" Microsoft.

Yay, SQL Server driver now under MIT license on

• GitHub: https://github.com/Microsoft/mssql-jdbc
• Maven Central: http://search.maven.org/#search%7Cga%7C1%7Cmssql-jdbc

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>6.1.0.jre8</version>
</dependency>

Answer for the "old" Microsoft:

For my use-case (integration testing) it was sufficient to use a system scope for the JDBC driver's dependency as such:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>3.0</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/sqljdbc4.jar</systemPath>
    <optional>true</optional>
</dependency>

That way, I could put the JDBC driver into local version control. No need to have each developer manually set stuff up in their own repositories.

I took inspiration from this answer to another Stack Overflow question and I've also blogged about it here.

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

The plugin doesn't look very robust. If you call .placeholder() again, it creates a new Placeholder instance while events are still bound to the old one.

Looking at the code, it looks like you could do:

$("#serMemtb").attr("placeholder", "Type a name (Lastname, Firstname)").blur();

EDIT

placeholder is an HTML5 attribute, guess who's not supporting it?

Your plugin doesn't really seem to help you overcome the fact that IE doesn't support it, so while my solution works, your plugin doesn't. Why don't you find one that does.

Thought this might help to someone, it happens because "When the number of data queries is greater than 1".reference

Just create another class and add along with the bootstrap container class. You can also use container-fluid though.

<div class="container full-width">
    <div class="row">
        ....
    </div>
</div>

The CSS part is pretty simple

* {
    margin: 0;
    padding: 0;
}
.full-width {
    width: 100%;
    min-width: 100%;
    max-width: 100%;
}

Hope this helps, Thanks!

The simplest way would be to directly subtract the date objects from one another.

For example:

var hours = Math.abs(date1 - date2) / 36e5;

The subtraction returns the difference between the two dates in milliseconds. 36e5 is the scientific notation for 60*60*1000, dividing by which converts the milliseconds difference into hours.

The property to set is => WindowStyle="None"

<Window x:Class="mdaframework.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Title="Start" Height="350" Width="525" ResizeMode="NoResize"  WindowStartupLocation="CenterScreen" WindowStyle="None">

I would suggest following design : Item Table: Itemid, taglist1, taglist2
this will be fast and make easy saving and retrieving the data at item level.

In parallel build another table: Tags tag do not make tag unique identifier and if you run out of space in 2nd column which contains lets say 100 items create another row.

Now while searching for items for a tag it will be super fast.

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

Your tomcat-users.xml looks good.

Make sure you have the manager/ application inside your $CATALINA_BASE/webapps/

• Linux:

You have to install tomcat-admin package: sudo apt-get install tomcat8-admin (for version 8)

• Windows:

I am using Eclipse. I had to copy the manager/ folder from C:\Program Files\apache-tomcat-8.5.20\webapps to my Eclipse workspace (~\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps\).

By this code for formating price in product list

echo Mage::helper('core')->currency($_product->getPrice());

I ran into this when trying to run spring boot from the command line...

mvn spring-boot:run

I accidentally mis-typed the command as...

mvn spring-boot run

So it was looking for the commands... run, build etc...

The best way is to create special source folder named resources and use it for all resource including log4j.properties. So, just put it there.

On the Java Resources folder that was automatically created by the Dynamic Web Project, right click and add a new Source Folder and name it 'resources'. Files here will then be exported to the war file to the classes directory

$('#myDiv').hide() will hide the div...

You can position your background image in an editor to be x pixels from the right side.

background: url(images_url) no-repeat right top;

The background image will be positioned in top right, but will appear to be x pixels from the right.

as @PhilHarvey said, you can use mysqld --verbose --help | grep datadir

Here's a solution to your problem using dplyr's filter function.

Although you can pass your data frame as the first argument to any dplyr function, I've used its %>% operator, which pipes your data frame to one or more dplyr functions (just filter in this case).

Once you are somewhat familiar with dplyr, the cheat sheet is very handy.

> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
   sub day
1    1   1
2    1   2
3    1   3
4    1   4

I'm Daniel Stenberg.

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

I'd personally make use of the table.insert function:

table.insert(a,"b");

This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.

var lat = homeMarker.getPosition().lat();
var lng = homeMarker.getPosition().lng();

See the google.maps.LatLng docs and google.maps.Marker getPosition().

Almost all public CDNs are pretty reliably. However, if you are worried about blocked google domain, then you can simply fallback to an alternative jQuery CDN. However, in such a case, you may prefer to do it opposite way and use some other CDN as your preferred option and fallback to Google CDN to avoid failed requests and waiting time:

<script src="https://pagecdn.io/lib/jquery/3.2.1/jquery.min.js"></script>
<script>
   window.jQuery || document.write('<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"><\/script>');
</script>

Do you have something against splitting it up?

...FROM <blah> 
   WHERE 
     (fieldA LIKE '%THIS%' OR fieldA LIKE '%THAT%') 
     AND something = else

Use

Intent myIntent = new Intent(v.getContext(), MyClass.class);

or

 Intent myIntent = new Intent(MyFragment.this.getActivity(), MyClass.class);

to start a new Activity. This is because you will need to pass Application or component context as a first parameter to the Intent Constructor when you are creating an Intent for a specific component of your application.

sqlplus user/password@sid < sqlfile.sql

This will also work from the DOS command line. In this case the file sqlfile.sql contains the SQL you wish to execute.

Answer:

Your traceback is telling you that int() takes integers, you are trying to give a decimal, so you need to use float():

a = float(a)

This should work as expected:

>>> int(input("Type a number: "))
Type a number: 0.3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '0.3'
>>> float(input("Type a number: "))
Type a number: 0.3
0.3

Computers store numbers in a variety of different ways. Python has two main ones. Integers, which store whole numbers (Z), and floating point numbers, which store real numbers (R). You need to use the right one based on what you require.

(As a note, Python is pretty good at abstracting this away from you, most other language also have double precision floating point numbers, for instance, but you don't need to worry about that. Since 3.0, Python will also automatically convert integers to floats if you divide them, so it's actually very easy to work with.)

Previous guess at answer before we had the traceback:

Your problem is that whatever you are typing is can't be converted into a number. This could be caused by a lot of things, for example:

>>> int(input("Type a number: "))
Type a number: -1
-1
>>> int(input("Type a number: "))
Type a number: - 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '- 1'

Adding a space between the - and 1 will cause the string not to be parsed correctly into a number. This is, of course, just an example, and you will have to tell us what input you are giving for us to be able to say for sure what the issue is.

Advice on code style:

y = [int(a)**(-2),int(a)**(-1.75),int(a)**(-1.5),int(a)**(-1.25),
            int(a)**(-1),int(a)**(-0.75),int(a)**(-0.5),int(a)**(-0.25),
            int(a)**(0),int(a)**(0.25),int(a)**(0.5),int(a)**(0.75),
            int(a)**1,int(a)**(1.25),int(a)**(1.5),int(a)**(1.75), int(a)**(2)]

This is an example of a really bad coding habit. Where you are copying something again and again something is wrong. Firstly, you use int(a) a ton of times, wherever you do this, you should instead assign the value to a variable, and use that instead, avoiding typing (and forcing the computer to calculate) the value again and again:

a = int(a)

In this example I assign the value back to a, overwriting the old value with the new one we want to use.

y = [a**i for i in x]

This code produces the same result as the monster above, without the masses of writing out the same thing again and again. It's a simple list comprehension. This also means that if you edit x, you don't need to do anything to y, it will naturally update to suit.

Also note that PEP-8, the Python style guide, suggests strongly that you don't leave spaces between an identifier and the brackets when making a function call.

These are the steps necessary to use OpenCV with Android Studio 1.2:

• Download OpenCV and extract the archive
• Open your app project in Android Studio
• Go to File -> New -> Import Module...
• Select sdk/java in the directory you extracted before
• Set Module name to opencv
• Press Next then Finish
• Open build.gradle under imported OpenCV module and update compileSdkVersion and buildToolsVersion to versions you have on your machine

• Add compile project(':opencv') to your app build.gradle

  dependencies {
      ...
      compile project(':opencv')
  }
  

• Press Sync Project with Gradle Files

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

Queue is an interface that extends Collection in Java. It has all the functions needed to support FIFO architecture.

For concrete implementation you may use LinkedList. LinkedList implements Deque which in turn implements Queue. All of these are a part of java.util package.

For details about method with sample example you can refer FIFO based Queue implementation in Java.

PS: Above link goes to my personal blog that has additional details on this.

It's often sufficient to use sibling's or parent's brush for the purpose, and that's easily available in wpf via retrieving their Foreground or Background property.

ref: Control.Background

It has 2 purposes.

yentup has given the first one.

It's used for raising your own errors.

if something:
    raise Exception('My error!')

The second is to reraise the current exception in an exception handler, so that it can be handled further up the call stack.

try:
  generate_exception()
except SomeException as e:
  if not can_handle(e):
    raise
  handle_exception(e)

one of the other tool (besides file) you can use is xdg-mime

eg xdg-mime query filetype <file>

if you have yum,

yum install xdg-utils.noarch

An example comparison of xdg-mime and file on a Subrip(subtitles) file

$ xdg-mime query filetype subtitles.srt
application/x-subrip

$ file --mime-type subtitles.srt
subtitles.srt: text/plain

in the above file only show it as plain text.

For a faster NLTK-based solution you could hash the set of words to avoid a linear search.

from nltk.corpus import words as nltk_words
def is_english_word(word):
    # creation of this dictionary would be done outside of 
    #     the function because you only need to do it once.
    dictionary = dict.fromkeys(nltk_words.words(), None)
    try:
        x = dictionary[word]
        return True
    except KeyError:
        return False

The right way to do that is:

for(std::vector<T>::iterator it = v.begin(); it != v.end(); ++it) {
    it->doSomething();
 }

Where T is the type of the class inside the vector. For example if the class was CActivity, just write CActivity instead of T.

This type of method will work on every STL (Not only vectors, which is a bit better).

If you still want to use indexes, the way is:

for(std::vector<T>::size_type i = 0; i != v.size(); i++) {
    v[i].doSomething();
}

Assign your image to a string. Eg image Now set icon to a fixed size label.

image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));

Here is another solution

var arr = Array.apply( null, { length: 4 } );
arr;  // [undefined, undefined, undefined, undefined] (in Chrome)
arr.length; // 4

The first argument of apply() is a this object binding, which we don't care about here, so we set it to null.

Array.apply(..) is calling the Array(..) function and spreading out the { length: 3 } object value as its arguments.

It is XOR operator. It is use to do bit operations on numbers. It has the behavior such that when you do a xor operation on same bits say 0 XOR 0 / 1 XOR 1 the result is 0. But if any of the bits is different then result is 1. So when you did 5^3 then you can look at these numbers 5, 6 in their binary forms and thus the expression becomes (101) XOR (110) which gives the result (011) whose decimal representation is 3.

Custom format

[>=1000]#,##0,"K";0

will give you:

Note the comma between the zero and the "K". To display millions or billions, use two or three commas instead.

Call below method just after calling the method for opening new window, this will close the current window.

private void close(){
    WindowEvent windowEventClosing = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
    Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(windowEventClosing);
}

Also in properties of JFrame, make sure defaultCloseOperation is set as DISPOSE.

After looking around on Google for a long time, trying out several solutions, both CSS, JavaScript and JQuery, i found that most of them were using an Image as the button. Some of them were hard to use, but i did manage to piece together something that ended out working out for me.

The important parts for me was:

• The Browse button had to be a Button (not an image).
• The button had to have a hover effect (to make it look nice).
• The Width of both the Text and the button had to be easy to adjust.
• The solution had to work in IE8, FF, Chrome and Safari.

This is the solution i came up with. And hope it can be of use to others as well.

Change the width of .file_input_textbox to change the width of the textbox.

Change the width of both .file_input_div, .file_input_button and .file_input_button_hover to change the width of the button. You might need to tweak a bit on the positions also. I never figured out why...

To test this solution, make a new html file and paste the content into it.

<html>
<head>

<style type="text/css">

.file_input_textbox {height:25px;width:200px;float:left; }
.file_input_div     {position: relative;width:80px;height:26px;overflow: hidden; }
.file_input_button  {width: 80px;position:absolute;top:0px;
                     border:1px solid #F0F0EE;padding:2px 8px 2px 8px; font-weight:bold; height:25px; margin:0px; margin-right:5px; }
.file_input_button_hover{width:80px;position:absolute;top:0px;
                     border:1px solid #0A246A; background-color:#B2BBD0;padding:2px 8px 2px 8px; height:25px; margin:0px; font-weight:bold; margin-right:5px; }
.file_input_hidden  {font-size:45px;position:absolute;right:0px;top:0px;cursor:pointer;
                     opacity:0;filter:alpha(opacity=0);-ms-filter:"alpha(opacity=0)";-khtml-opacity:0;-moz-opacity:0; }
</style>
</head>
<body>
    <input type="text" id="fileName" class="file_input_textbox" readonly="readonly">
 <div class="file_input_div">
  <input id="fileInputButton" type="button" value="Browse" class="file_input_button" />
  <input type="file" class="file_input_hidden" 
      onchange="javascript: document.getElementById('fileName').value = this.value" 
      onmouseover="document.getElementById('fileInputButton').className='file_input_button_hover';"
      onmouseout="document.getElementById('fileInputButton').className='file_input_button';" />

Use a div #overlay with your loading info / .gif that will cover all your page:

<div id="overlay">
     <img src="loading.gif" alt="Loading" />
     Loading...
</div>

jQuery:

$(window).load(function(){
   // PAGE IS FULLY LOADED  
   // FADE OUT YOUR OVERLAYING DIV
   $('#overlay').fadeOut();
});

Here's an example with a Loading bar:

jsBin demo

  <div id="overlay">
    <div id="progstat"></div>
    <div id="progress"></div>
  </div>

  <div id="container">
    <img src="http://placehold.it/3000x3000/cf5">
  </div>

CSS:

*{margin:0;}
body{ font: 200 16px/1 sans-serif; }
img{ width:32.2%; }

#overlay{
  position:fixed;
  z-index:99999;
  top:0;
  left:0;
  bottom:0;
  right:0;
  background:rgba(0,0,0,0.9);
  transition: 1s 0.4s;
}
#progress{
  height:1px;
  background:#fff;
  position:absolute;
  width:0;                /* will be increased by JS */
  top:50%;
}
#progstat{
  font-size:0.7em;
  letter-spacing: 3px;
  position:absolute;
  top:50%;
  margin-top:-40px;
  width:100%;
  text-align:center;
  color:#fff;
}

JavaScript:

;(function(){
  function id(v){ return document.getElementById(v); }
  function loadbar() {
    var ovrl = id("overlay"),
        prog = id("progress"),
        stat = id("progstat"),
        img = document.images,
        c = 0,
        tot = img.length;
    if(tot == 0) return doneLoading();

    function imgLoaded(){
      c += 1;
      var perc = ((100/tot*c) << 0) +"%";
      prog.style.width = perc;
      stat.innerHTML = "Loading "+ perc;
      if(c===tot) return doneLoading();
    }
    function doneLoading(){
      ovrl.style.opacity = 0;
      setTimeout(function(){ 
        ovrl.style.display = "none";
      }, 1200);
    }
    for(var i=0; i<tot; i++) {
      var tImg     = new Image();
      tImg.onload  = imgLoaded;
      tImg.onerror = imgLoaded;
      tImg.src     = img[i].src;
    }    
  }
  document.addEventListener('DOMContentLoaded', loadbar, false);
}());

I'm not familiar with grep but with Select-String you can do:

Get-ChildItem filename.txt | Select-String -Pattern <regexPattern>

You can also do that with Get-Content:

(Get-Content filename.txt) -match 'pattern'

You can using onAttach or if you do not want to put onAttach everywhere then you can put a method that returns ApplicationContext on the main App class :

public class App {
    ...  
    private static Context context;

    @Override
    public void onCreate() {
        super.onCreate();
        context = this;
    }

    public static Context getContext() {
        return context;
    }
    ...
}

After that you can re-use it everywhere in all over your project, like this :

App.getContext().getString(id)

Please let me know if this does not work for you.

I ran into this issue when I was manually beginning and committing transactions inside of method annotated as @Transactional. I fixed the problem by detecting if an active transaction already existed.

//Detect underlying transaction
if (session.getTransaction() != null && session.getTransaction().isActive()) {
    myTransaction = session.getTransaction();
    preExistingTransaction = true;
} else {
    myTransaction = session.beginTransaction();
}

Then I allowed Spring to handle committing the transaction.

private void finishTransaction() {
    if (!preExistingTransaction) {
        try {
            tx.commit();
        } catch (HibernateException he) {
            if (tx != null) {
                tx.rollback();
            }
            log.error(he);
        } finally {
            if (newSessionOpened) {
                SessionFactoryUtils.closeSession(session);
                newSessionOpened = false;
                maxResults = 0;
            }
        }
    }
}

You are used to using the javascript if, and I assume you know how it works.

in is a Pythonic way of implementing iteration. It's supposed to be easier for non-programmatic thinkers to adopt, but that can sometimes make it harder for programmatic thinkers, ironically.

When you say if x in y, you are literally saying:

"if x is in y", which assumes that y has an index. In that if statement then, each object at each index in y is checked against the condition.

Similarly,

for x in y

iterates through x's in y, where y is that indexable set of items.

Think of the if situation this way (pseudo-code):

for i in next:
    if i == "0" || i == "1":
        how_much = int(next)

It takes care of the iteration over next for you.

Happy coding!

You can only use the window.close function when you have opened the window using window.open(), so I use the following function:

function close_window(url){
    var newWindow = window.open('', '_self', ''); //open the current window
    window.close(url);
 }

I had this problem (403 error for each package) and I found nothing great in the internet to solve it. My .npmrc file inside my user folder was wrong and misunderstood. I changed this npmrc line from

proxy=http://XX.XX.XXX.XXX:XXX/

to :

proxy = XX.XX.XXX.XXX:XXXX

I used SOAP UI for functional and automated testing. SOAP UI allows you to run the tests on the click of a button. There is also a spring controllers testing page created by Ted Young. I used this article to create Rest unit tests in our application.

You should be get the data through the dataset attributes

var data = element.dataset;

dataset is useful tool for get data-attribute

Write a Boolean function that checks the regex and use apply on the column

foo[foo['b'].apply(regex_function)]

You don't need to use the asterisk to accept a list.

Simply give the argument a name in the definition, and pass in a list like

def takes_list(a_list):
    for item in a_list:
         print item

Less and Sass are CSS pre-processors which extend CSS language in valuable ways. Just one of many improvements they offer is just the option you're looking for. There are some very good answers with Less and I will add Sass solution.

Sass has extend option which allows one class to be fully extended to another one. More about extend you can read in this article

My problem was not related to skype as i didn't had it installed. The solution I found was that 2 .dll files(msvcp110.dll, msvcr110.dll) were missing from the directory :

C:\wamp\bin\apache\apache2.4.9\bin

So I copied these 2 files to all these locations just in case and restarted wamp it worked

C:\wamp
C:\wamp\bin\apache\apache2.4.9\bin
C:\wamp\bin\apache\apache2.4.9
C:\wamp\bin\mysql\mysql5.6.17
C:\wamp\bin\php\php5.5.12

I hope this helps someone out.

If you write Perl with use strict;, then you'll find that the one line syntax isn't valid, even when declared.

With:

my ($newstring = $oldstring) =~ s/foo/bar/;

You get:

Can't declare scalar assignment in "my" at script.pl line 7, near ") =~"
Execution of script.pl aborted due to compilation errors.

Instead, the syntax that you have been using, while a line longer, is the syntactically correct way to do it with use strict;. For me, using use strict; is just a habit now. I do it automatically. Everyone should.

#!/usr/bin/env perl -wT

use strict;

my $oldstring = "foo one foo two foo three";
my $newstring = $oldstring;
$newstring =~ s/foo/bar/g;

print "$oldstring","\n";
print "$newstring","\n";

If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-

[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb

Mysql would then open this file for each user account read the credentials and open the selected database.

Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Result:

"Hello, this is Mike"

To add a completely plain JavaScript solution that addressed @icedwater's issue with form submission, here's a complete solution with form.

NOTE: This is for "modern browsers", including IE9+. The IE8 version isn't much more complicated, and can be learned here.

Fiddle: https://jsfiddle.net/rufwork/gm6h25th/1/

HTML

<body>
    <form>
        <input type="text" id="txt" />
        <input type="button" id="go" value="Click Me!" />
        <div id="outige"></div>
    </form>
</body>

JavaScript

// The document.addEventListener replicates $(document).ready() for
// modern browsers (including IE9+), and is slightly more robust than `onload`.
// More here: https://stackoverflow.com/a/21814964/1028230
document.addEventListener("DOMContentLoaded", function() {
    var go = document.getElementById("go"),
        txt = document.getElementById("txt"),
        outige = document.getElementById("outige");

    // Note that jQuery handles "empty" selections "for free".
    // Since we're plain JavaScripting it, we need to make sure this DOM exists first.
    if (txt && go)    {
        txt.addEventListener("keypress", function (e) {
            if (event.keyCode === 13)   {
                go.click();
                e.preventDefault(); // <<< Most important missing piece from icedwater
            }
        });

        go.addEventListener("click", function () {
            if (outige) {
                outige.innerHTML += "Clicked!<br />";
            }
        });
    }
});

Use the :first-child selector.

In your example...

$('div.alldivs div:first-child')

This will also match any first child descendents that meet the selection criteria.

While :first matches only a single element, the :first-child selector can match more than one: one for each parent. This is equivalent to :nth-child(1).

For the first matched only, use the :first selector.

Alternatively, Felix Kling suggested using the direct descendent selector to get only direct children...

$('div.alldivs > div:first-child')

NPM shrinkwrap offers a nice solution to this problem. It allows us to override that version of a particular dependency of a particular sub-module.

Essentially, when you run npm install, npm will first look in your root directory to see whether a npm-shrinkwrap.json file exists. If it does, it will use this first to determine package dependencies, and then falling back to the normal process of working through the package.json files.

To create an npm-shrinkwrap.json, all you need to do is

 npm shrinkwrap --dev

code:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

You can use substr

for example:

new Date().getFullYear().toString().substr(-2)
