Here's an utility function that I wrote to wrap the retry until success into a neater package. It uses the same basic structure, but prevents repetition. It could be modified to catch and rethrow the exception on the final try relatively easily.

def try_until(func, max_tries, sleep_time):
    for _ in range(0,max_tries):
        try:
            return func()
        except:
            sleep(sleep_time)
    raise WellNamedException()
    #could be 'return sensibleDefaultValue'

Can then be called like this

result = try_until(my_function, 100, 1000)

If you need to pass arguments to my_function, you can either do this by having try_until forward the arguments, or by wrapping it in a no argument lambda:

result = try_until(lambda : my_function(x,y,z), 100, 1000)

Remember that after installing Imagick (or indeed any PHP module) you need to restart your web server and/or php-fpm if you're using it, for the module to appear in phpinfo().

In order to keep track of dependency issues, I like to use the conda installer, which simply boils down to:

conda install openpyxl

I just had this problem setting up my new laptop. The issue for me was that my toolchain (CodeSourcery) is 32bit and I had not installed the 32bit libs.

sudo apt-get install ia32-libs

You could implement a showfile function which takes in parameters of the data returned from the WEBApi, and a filename for the file you are trying to download. What I did was create a separate browser service identifies the user's browser and then handles the rendering of the file based on the browser. For instance if the target browser is chrome on an ipad, you have to use javascripts FileReader object.

FileService.showFile = function (data, fileName) {
    var blob = new Blob([data], { type: 'application/pdf' });

    if (BrowserService.isIE()) {
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    }
    else if (BrowserService.isChromeIos()) {
        loadFileBlobFileReader(window, blob, fileName);
    }
    else if (BrowserService.isIOS() || BrowserService.isAndroid()) {
        var url = URL.createObjectURL(blob);
        window.location.href = url;
        window.document.title = fileName;
    } else {
        var url = URL.createObjectURL(blob);
        loadReportBrowser(url, window,fileName);
    }
}


function loadFileBrowser(url, window, fileName) {
    var iframe = window.document.createElement('iframe');
    iframe.src = url
    iframe.width = '100%';
    iframe.height = '100%';
    iframe.style.border = 'none';
    window.document.title = fileName;
    window.document.body.appendChild(iframe)
    window.document.body.style.margin = 0;
}

function loadFileBlobFileReader(window, blob,fileName) {
    var reader = new FileReader();
    reader.onload = function (e) {
        var bdata = btoa(reader.result);
        var datauri = 'data:application/pdf;base64,' + bdata;
        window.location.href = datauri;
        window.document.title = fileName;
    }
    reader.readAsBinaryString(blob);
}

I would add that if you are upgrading from Sublime Text 2, go into /usr/bin and delete your old subl first before following the same instructions above. It's worth the upgrade.

If the value is between –2147483648 and 2147483647, cast(string_filed as int) will work. else cast(string_filed as bigint) will work

    hive> select cast('2147483647' as int);
    OK
    2147483647
    
    hive> select cast('2147483648' as int);
    OK
    NULL
    
    hive> select cast('2147483648' as bigint);
    OK
    2147483648

In my case, I needed to use RedirectToAction to solve the problem.

[HttpGet]
[ControleDeAcessoAuthorize("Report/ExportToPDF")]
public ActionResult ExportToPDF(int id, string month, string output)
{
    try
    {
        // Validate
        if (output != "PDF")
        {
            throw new Exception("Invalid output.");
        }
        else
        {
            ...// code to generate report in PDF format
        }
    }
    catch (Exception ex)
    {
        return RedirectToAction("Error");
    }
}

[ControleDeAcessoAuthorize("Report/Error")]
public ActionResult Error()
{
    return View();
}

You may also want to be aware of the difference between, for example, Sys.setenv(LANG = "ru") and Sys.setlocale(locale = "ru_RU.utf8").

> Sys.setlocale(locale = "ru_RU.utf8")
[1] "LC_CTYPE=ru_RU.utf8;LC_NUMERIC=C;LC_TIME=ru_RU.utf8;LC_COLLATE=ru_RU.utf8;LC_MONETARY=ru_RU.utf8;LC_MESSAGES=en_IE.utf8;LC_PAPER=en_IE.utf8;LC_NAME=en_IE.utf8;LC_ADDRESS=en_IE.utf8;LC_TELEPHONE=en_IE.utf8;LC_MEASUREMENT=en_IE.utf8;LC_IDENTIFICATION=en_IE.utf8"

If you are interested in changing the behaviour of functions that refer to one of these elements (e.g strptime to extract dates), you should use Sys.setlocale(). See ?Sys.setlocale for more details. In order to see all available languages on a linux system, you can run

system("locale -a", intern = TRUE)

If you are using jupyter notebook Try:

!python --version

If you are using terminal Try:

 python --version

Open your.gitconfig file to add the longpaths property. So it will look like the following:

[core]
symlinks = false
autocrlf = true
longpaths = true

See the Parameter Expansion section in the Bash man page. A[@] returns the contents of the array, :1:2 takes a slice of length 2, starting at index 1.

A=( foo bar "a  b c" 42 )
B=("${A[@]:1:2}")
C=("${A[@]:1}")       # slice to the end of the array
echo "${B[@]}"        # bar a  b c
echo "${B[1]}"        # a  b c
echo "${C[@]}"        # bar a  b c 42
echo "${C[@]: -2:2}"  # a  b c 42 # The space before the - is necesssary

Note that the fact that "a b c" is one array element (and that it contains an extra space) is preserved.

Also if you want selected field from table and aggregated then as array .

SELECT json_agg(json_build_object('data_a',a,
                                  'data_b',b,
))  from t;

The result will come .

 [{'data_a':1,'data_b':'value1'}
  {'data_a':2,'data_b':'value2'}]

You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.

Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/

Use splatting.

$CurlArgument = '-u', '[email protected]:yyyy',
                '-X', 'POST',
                'https://xxx.bitbucket.org/1.0/repositories/abcd/efg/pull-requests/2229/comments',
                '--data', 'content=success'
$CURLEXE = 'C:\Program Files\Git\mingw64\bin\curl.exe'
& $CURLEXE @CurlArgument

Generally I'd recommend something cross-platform like cURL, POCO, or Qt. However, here is a Windows example!:

#include <atlbase.h>
#include <msxml6.h>
#include <comutil.h> // _bstr_t

HRESULT hr;
CComPtr<IXMLHTTPRequest> request;

hr = request.CoCreateInstance(CLSID_XMLHTTP60);
hr = request->open(
    _bstr_t("GET"),
    _bstr_t("https://www.google.com/images/srpr/logo11w.png"),
    _variant_t(VARIANT_FALSE),
    _variant_t(),
    _variant_t());
hr = request->send(_variant_t());

// get status - 200 if succuss
long status;
hr = request->get_status(&status);

// load image data (if url points to an image)
VARIANT responseVariant;
hr = request->get_responseStream(&responseVariant);
IStream* stream = (IStream*)responseVariant.punkVal;
CImage *image = new CImage();
image->Load(stream);
stream->Release();

Please try this. This query can be used for date comparison

select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'

TEXT is a string data type that can store up to 65,535 characters. But still if you want to store more data then change its data type to LONGTEXT

ALTER TABLE name_tabel CHANGE text_field LONGTEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

String string = "Ram is going to school";
String[] arrayOfString = string.split("\\s+");

Just to add my two cents to @dbr's answer, following is an example of how to implement this sentence from the official documentation he's cited:

"[...] to return a string that would yield an object with the same value when passed to eval(), [...]"

Given this class definition:

class Test(object):
    def __init__(self, a, b):
        self._a = a
        self._b = b

    def __str__(self):
        return "An instance of class Test with state: a=%s b=%s" % (self._a, self._b)

    def __repr__(self):
        return 'Test("%s","%s")' % (self._a, self._b)

Now, is easy to serialize instance of Test class:

x = Test('hello', 'world')
print 'Human readable: ', str(x)
print 'Object representation: ', repr(x)
print

y = eval(repr(x))
print 'Human readable: ', str(y)
print 'Object representation: ', repr(y)
print

So, running last piece of code, we'll get:

Human readable:  An instance of class Test with state: a=hello b=world
Object representation:  Test("hello","world")

Human readable:  An instance of class Test with state: a=hello b=world
Object representation:  Test("hello","world")

But, as I said in my last comment: more info is just here!

I was looking for a similar solution and this is what I would suggest. In the OnTouch method, record the time for MotionEvent.ACTION_DOWN event and then for MotionEvent.ACTION_UP, record the time again. This way you can set your own threshold also. After experimenting few times you will know the max time in millis it would need to record a simple touch and you can use this in move or other method as you like.

Hope this helped. Please comment if you used a different method and solved your problem.

You can change the index as explained already using set_index. You don't need to manually swap rows with columns, there is a transpose (data.T) method in pandas that does it for you:

> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                    ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> newdf = df.set_index('Locality').T
> newdf

Locality    ABBOTSFORD  ABERFELDIE
2005        427000      534000
2006        448000      600000

then you can fetch the dataframe column values and transform them to a list:

> newdf['ABBOTSFORD'].values.tolist()

[427000, 448000]

The /sys filesystem should contain plenty information for your quest. My system (2.6.32-40-generic #87-Ubuntu) suggests:

/sys/class/tty

Which gives you descriptions of all TTY devices known to the system. A trimmed down example:

# ll /sys/class/tty/ttyUSB*
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/ttyUSB0/tty/ttyUSB0/
lrwxrwxrwx 1 root root 0 2012-03-28 20:44 /sys/class/tty/ttyUSB1 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/ttyUSB1/tty/ttyUSB1/

Following one of these links:

# ll /sys/class/tty/ttyUSB0/
insgesamt 0
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ./
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ../
-r--r--r-- 1 root root 4096 2012-03-28 20:49 dev
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 device -> ../../../ttyUSB0/
drwxr-xr-x 2 root root    0 2012-03-28 20:49 power/
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 subsystem -> ../../../../../../../../../../class/tty/
-rw-r--r-- 1 root root 4096 2012-03-28 20:43 uevent

Here the dev file contains this information:

# cat /sys/class/tty/ttyUSB0/dev
188:0

This is the major/minor node. These can be searched in the /dev directory to get user-friendly names:

# ll -R /dev |grep "188, *0"
crw-rw----   1 root dialout 188,   0 2012-03-28 20:44 ttyUSB0

The /sys/class/tty dir contains all TTY devices but you might want to exclude those pesky virtual terminals and pseudo terminals. I suggest you examine only those which have a device/driver entry:

# ll /sys/class/tty/*/device/driver
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS0/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS1/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS2/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS3/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/
lrwxrwxrwx 1 root root 0 2012-03-28 21:15 /sys/class/tty/ttyUSB1/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/

You can't remove anything from an array - they're always fixed length. Once you've created an array of length 3, that array will always have length 3.

You'd be better off with a List<String>, e.g. an ArrayList<String>:

List<String> list = new ArrayList<String>();
list.add("google");
list.add("microsoft");
list.add("apple");
System.out.println(list.size()); // 3

list.remove("apple");
System.out.println(list.size()); // 2

Collections like this are generally much more flexible than working with arrays directly.

EDIT: For removal:

void removeRandomElement(List<?> list, Random random)
{
    int index = random.nextInt(list.size());
    list.remove(index);
}

If you need to know the default collation for a newly created database use:

SELECT SERVERPROPERTY('Collation')

This is the server collation for the SQL Server instance that you are running.

Any reference to current date/time will disable the query cache for that selection:

SELECT *,NOW() FROM TABLE

See "Prerequisites and Notes for MySQL Query Cache Use" @ http://dev.mysql.com/tech-resources/articles/mysql-query-cache.html

it should be enough to mark your aspect method like this:

@After("@annotation(com.marcot.CommitTransaction)")
    public void after() {

have a look at this for a step by step guide on this.

In case someone wants to rename all the keys at once providing a list with the new names:

def rename_keys(dict_, new_keys):
    """
     new_keys: type List(), must match length of dict_
    """

    # dict_ = {oldK: value}
    # d1={oldK:newK,} maps old keys to the new ones:  
    d1 = dict( zip( list(dict_.keys()), new_keys) )

          # d1{oldK} == new_key 
    return {d1[oldK]: value for oldK, value in dict_.items()}

Or you can do this without using Delay.

set /a "counter=0"

-> your for loop here

do (
   statement1
   statement2
   call :increaseby1
 )

:increaseby1
set /a "counter+=1"

Is this really possible.

Yes.

function a(x) {    // <-- function_x000D_
  function b(y) { // <-- inner function_x000D_
    return x + y; // <-- use variables from outer scope_x000D_
  }_x000D_
  return b;       // <-- you can even return a function._x000D_
}_x000D_
console.log(a(3)(4));

You can use this simple online service. It supports both HTML and PDF.

For BSD sockets I'd check out Beej's guide. When recv returns 0 you know the other side disconnected.

Now you might actually be asking, what is the easiest way to detect the other side disconnecting? One way of doing it is to have a thread always doing a recv. That thread will be able to instantly tell when the client disconnects.

Whether an object is mutable or not depends on its type. This doesn't depend on whether or not it has certain methods, nor on the structure of the class hierarchy.

User-defined types (i.e. classes) are generally mutable. There are some exceptions, such as simple sub-classes of an immutable type. Other immutable types include some built-in types such as int, float, tuple and str, as well as some Python classes implemented in C.

A general explanation from the "Data Model" chapter in the Python Language Reference":

The value of some objects can change. Objects whose value can change are said to be mutable; objects whose value is unchangeable once they are created are called immutable.

(The value of an immutable container object that contains a reference to a mutable object can change when the latter’s value is changed; however the container is still considered immutable, because the collection of objects it contains cannot be changed. So, immutability is not strictly the same as having an unchangeable value, it is more subtle.)

An object’s mutability is determined by its type; for instance, numbers, strings and tuples are immutable, while dictionaries and lists are mutable.

It is an attribute, but a boolean one (so it doesn't need a name, just a value -- I know, it's weird). You can set the property equivalent in Javascript:

document.getElementsByName("myButton")[0].disabled = true;

array_splice — Remove a portion of the array and replace it with something else:

$input = array(1, 2, 3, 4, 5, 6);
array_splice($input, 5); // $input is now array(1, 2, 3, 4, 5)

From PHP manual:

array array_splice ( array &$input , int $offset [, int $length = 0 [, mixed $replacement]])

If length is omitted, removes everything from offset to the end of the array. If length is specified and is positive, then that many elements will be removed. If length is specified and is negative then the end of the removed portion will be that many elements from the end of the array. Tip: to remove everything from offset to the end of the array when replacement is also specified, use count($input) for length .

The best and most intuitive way is to use serialEvent() callback Arduino defines along with loop() and setup().

I've built a small library a while back that handles message reception, but never had time to opensource it. This library receives \n terminated lines that represent a command and arbitrary payload, space-separated. You can tweak it to use your own protocol easily.

First of all, a library, SerialReciever.h:

#ifndef __SERIAL_RECEIVER_H__
#define __SERIAL_RECEIVER_H__
    
class IncomingCommand {
  private:
    static boolean hasPayload;
  public:
    static String command;
    static String payload;
    static boolean isReady;
    static void reset() {
      isReady = false;
      hasPayload = false;
      command = "";
      payload = "";
    }
    static boolean append(char c) {
      if (c == '\n') {
        isReady = true;
        return true;
      }
      if (c == ' ' && !hasPayload) {
        hasPayload = true;
        return false;
      }
      if (hasPayload)
        payload += c;
      else
        command += c;
      return false;
    }
};
    
boolean IncomingCommand::isReady = false;
boolean IncomingCommand::hasPayload = false;
String IncomingCommand::command = false;
String IncomingCommand::payload = false;
    
#endif // #ifndef __SERIAL_RECEIVER_H__

To use it, in your project do this:

#include <SerialReceiver.h>
    
void setup() {
  Serial.begin(115200);
  IncomingCommand::reset();
}
    
void serialEvent() {
  while (Serial.available()) {
    char inChar = (char)Serial.read();
    if (IncomingCommand::append(inChar))
      return;
  }
}

To use the received commands:

void loop() {
  if (!IncomingCommand::isReady) {
    delay(10);
    return;
  }

executeCommand(IncomingCommand::command, IncomingCommand::payload); // I use registry pattern to handle commands, but you are free to do whatever suits your project better.
    
IncomingCommand::reset();

Open servers view, open Timeouts and set up Start

You can use T-Regx library, that doesn't need delimiters

pattern('^([0-9]+)$')->match($input);

For React Native version = 0.60, in your root file create a file called react-native.config.js and put the followings, then just run react-native link

module.exports = {
  assets: ["./assets/fonts"]
}

MySQL supports Spatial data types and Point is a single-value type which can be used. Example:

CREATE TABLE `buildings` (
  `coordinate` POINT NOT NULL,
  /* Even from v5.7.5 you can define an index for it */
  SPATIAL INDEX `SPATIAL` (`coordinate`)
) ENGINE=InnoDB;

/* then for insertion you can */
INSERT INTO `buildings` 
(`coordinate`) 
VALUES
(POINT(40.71727401 -74.00898606));

I would try any(byte[].class)

The following resolved the issue:

ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("JavaScript");
String str = "4*5";
System.out.println(engine.eval(str));

<script type="text/javascript">
    function hide(){
        document.getElementById('id').hidden = true;
    }
    function show(){
        document.getElementById('id').hidden = false;
    }
</script>

I believe some of the respondents of this question have missed the broader implication of the fold function as an abstract tool. Yes, sum can do the same thing for a list of integers, but this is a trivial case. fold is more generic. It is useful when you have a sequence of data structures of varying shape and want to cleanly express an aggregation. So instead of having to build up a for loop with an aggregate variable and manually recompute it each time, a fold function (or the Python version, which reduce appears to correspond to) allows the programmer to express the intent of the aggregation much more plainly by simply providing two things:

• A default starting or "seed" value for the aggregation.
• A function that takes the current value of the aggregation (starting with the "seed") and the next element in the list, and returns the next aggregation value.

As dplyr 1.0.0 deprecated the scoped variants which @Feng Mai nicely showed, here is an update with the new syntax. This might be useful because in this case, across() doesn't work, and it took me some time to figure out the solution as follows.

The goal was to extract all rows that contain at least one 0 in a column.

df %>% 
  rowwise() %>% 
  filter(any(c_across(everything(.)) == 0))

with the data

df <- data.frame(a = 1:4, b= 1:0, c=0:3)
df <- rbind(df, c(0,0,0))
df <- rbind(df, c(9,9,9))

# A tibble: 4 x 3
# Rowwise: 
      a     b     c
  <dbl> <dbl> <dbl>
1     1     1     0
2     2     0     1
3     4     0     3
4     0     0     0

So it correctly doesn't return the last row containing all 9s.

I also had the newest version of ca-certificates installed but was still getting the error:

curl: (77) error setting certificate verify locations:
  CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none

The issue was that curl expected the certificate to be at the path /etc/pki/tls/certs/ca-bundle.crt but could not find it because it was at the path /etc/ssl/certs/ca-certificates.crt.

Copying my certificate to the expected destination by running

sudo cp /etc/ssl/certs/ca-certificates.crt /etc/pki/tls/certs/ca-bundle.crt

worked for me. You will need to create folders for the target destination if they do not exist by running

sudo mkdir -p /etc/pki/tls/certs

If needed, modify the above command to make the destination file name match the path expected by curl, i.e. replace /etc/pki/tls/certs/ca-bundle.crt with the path following "CAfile:" in your error message.

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

The Python reference manual includes several string literals that can be used in a string. These special sequences of characters are replaced by the intended meaning of the escape sequence.

Here is a table of some of the more useful escape sequences and a description of the output from them.

Escape Sequence       Meaning
\t                    Tab
\\                    Inserts a back slash (\)
\'                    Inserts a single quote (')
\"                    Inserts a double quote (")
\n                    Inserts a ASCII Linefeed (a new line)

Basic Example

If i wanted to print some data points separated by a tab space I could print this string.

DataString = "0\t12\t24"
print (DataString)

Returns

0    12    24

Example for Lists

Here is another example where we are printing the items of list and we want to sperate the items by a TAB.

DataPoints = [0,12,24]
print (str(DataPoints[0]) + "\t" + str(DataPoints[1]) + "\t" + str(DataPoints[2]))

Returns

0    12    24

Raw Strings

Note that raw strings (a string which include a prefix "r"), string literals will be ignored. This allows these special sequences of characters to be included in strings without being changed.

DataString = r"0\t12\t24"
print (DataString)

Returns

0\t12\t24

Which maybe an undesired output

String Lengths

It should also be noted that string literals are only one character in length.

DataString = "0\t12\t24"
print (len(DataString))

Returns

7

The raw string has a length of 9.

Look into the File class.

You can create a streamwriter with

StreamWriter sw = File.Create(....) 

You can open an existing file with

File.Open(...)

You can append text easily with

File.AppendAllText(...);

You might need a bit more background on what a Materialized View actually is. In Oracle these are an object that consists of a number of elements when you try to build it elsewhere.

An MVIEW is essentially a snapshot of data from another source. Unlike a view the data is not found when you query the view it is stored locally in a form of table. The MVIEW is refreshed using a background procedure that kicks off at regular intervals or when the source data changes. Oracle allows for full or partial refreshes.

In SQL Server, I would use the following to create a basic MVIEW to (complete) refresh regularly.

First, a view. This should be easy for most since views are quite common in any database Next, a table. This should be identical to the view in columns and data. This will store a snapshot of the view data. Then, a procedure that truncates the table, and reloads it based on the current data in the view. Finally, a job that triggers the procedure to start it's work.

Everything else is experimentation.

I wrote a small tool that does just that. Code is available on github.

To dump the results of one (or more) SQL queries to one (or more) CSV files:

java -jar sql_dumper.jar /path/sql/files/ /path/out/ user pass jdbcString

Take a look at "using WCF Services with PHP". It explains the basics of what you need.

As a theory summary:

WCF or Windows Communication Foundation is a technology that allow to define services abstracted from the way - the underlying communication method - they'll be invoked.

The idea is that you define a contract about what the service does and what the service offers and also define another contract about which communication method is used to actually consume the service, be it TCP, HTTP or SOAP.

You have the first part of the article here, explaining how to create a very basic WCF Service.

More resources:

Using WCF with PHP5.

Aslo take a look to NuSOAP. If you now NuSphere this is a toolkit to let you connect from PHP to an WCF service.

Orion Adrian, let me invert your post to see how unfounded your remarks are, because a lot can be said about C++ as well. And telling that Java/C# compiler optimize away empty functions does really make you sound like you are not my expert in optimization, because a) why should a real program contain empty functions, except for really bad legacy code, b) that is really not black and bleeding edge optimization.

Apart from that phrase, you ranted blatantly about pointers, but don't objects in Java and C# basically work like C++ pointers? May they not overlap? May they not be null? C (and most C++ implementations) has the restrict keyword, both have value types, C++ has reference-to-value with non-null guarantee. What do Java and C# offer?

>>>>>>>>>>

Generally, C and C++ can be just as fast or faster because the AOT compiler -- a compiler that compiles your code before deployment, once and for all, on your high memory many core build server -- can make optimizations that a C# compiled program cannot because it has a ton of time to do so. The compiler can determine if the machine is Intel or AMD; Pentium 4, Core Solo, or Core Duo; or if supports SSE4, etc, and if your compiler does not support runtime dispatch, you can solve for that yourself by deploying a handful of specialized binaries.

A C# program is commonly compiled upon running it so that it runs decently well on all machines, but is not optimized as much as it could be for a single configuration (i.e. processor, instruction set, other hardware), and it must spend some time first. Features like loop fission, loop inversion, automatic vectorization, whole program optimization, template expansion, IPO, and many more, are very hard to be solved all and completely in a way that does not annoy the end user.

Additionally certain language features allow the compiler in C++ or C to make assumptions about your code that allows it to optimize certain parts away that just aren't safe for the Java/C# compiler to do. When you don't have access to the full type id of generics or a guaranteed program flow there's a lot of optimizations that just aren't safe.

Also C++ and C do many stack allocations at once with just one register incrementation, which surely is more efficient than Javas and C# allocations as for the layer of abstraction between the garbage collector and your code.

Now I can't speak for Java on this next point, but I know that C++ compilers for example will actually remove methods and method calls when it knows the body of the method is empty, it will eliminate common subexpressions, it may try and retry to find optimal register usage, it does not enforce bounds checking, it will autovectorize loops and inner loops and will invert inner to outer, it moves conditionals out of loops, it splits and unsplits loops. It will expand std::vector into native zero overhead arrays as you'd do the C way. It will do inter procedural optimmizations. It will construct return values directly at the caller site. It will fold and propagate expressions. It will reorder data into a cache friendly manner. It will do jump threading. It lets you write compile time ray tracers with zero runtime overhead. It will make very expensive graph based optimizations. It will do strength reduction, were it replaces certain codes with syntactically totally unequal but semantically equivalent code (the old "xor foo, foo" is just the simplest, though outdated optimization of such kind). If you kindly ask it, you may omit IEEE floating point standards and enable even more optimizations like floating point operand re-ordering. After it has massaged and massacred your code, it might repeat the whole process, because often, certain optimizations lay the foundation for even certainer optimizations. It might also just retry with shuffled parameters and see how the other variant scores in its internal ranking. And it will use this kind of logic throughout your code.

So as you can see, there are lots of reasons why certain C++ or C implementations will be faster.

Now this all said, many optimizations can be made in C++ that will blow away anything that you could do with C#, especially in the number crunching, realtime and close-to-metal realm, but not exclusively there. You don't even have to touch a single pointer to come a long way.

So depending on what you're writing I would go with one or the other. But if you're writing something that isn't hardware dependent (driver, video game, etc), I wouldn't worry about the performance of C# (again can't speak about Java). It'll do just fine.

<<<<<<<<<<

Generally, certain generalized arguments might sound cool in specific posts, but don't generally sound certainly credible.

Anyways, to make peace: AOT is great, as is JIT. The only correct answer can be: It depends. And the real smart people know that you can use the best of both worlds anyways.

• tput cols tells you the number of columns.
• tput lines tells you the number of rows.

Keep in mind that international users may be using a decimal separator other than . in which case values can get mixed up or just become nil when using intValue on a string.

For example, in the UK 1.23 is written 1,23, so the number 1.777 would be input by user as 1,777, which, as .intValue, will be 1777 not 1 (truncated).

I've made a macro that will convert input text to an NSNumber based on a locale argument which can be nil (if nil it uses device current locale).

#define stringToNumber(__string, __nullable_locale) (\
(^NSNumber *(void){\
NSLocale *__locale = __nullable_locale;\
if (!__locale) {\
__locale = [NSLocale currentLocale];\
}\
NSString *__string_copy = [__string stringByReplacingOccurrencesOfString:__locale.groupingSeparator withString:@""];\
__string_copy = [__string_copy stringByReplacingOccurrencesOfString:__locale.decimalSeparator withString:@"."];\
return @([__string_copy doubleValue]);\
})()\
)

Yes, the biggest difference is that reject is a callback function that gets carried out after the promise is rejected, whereas throw cannot be used asynchronously. If you chose to use reject, your code will continue to run normally in asynchronous fashion whereas throw will prioritize completing the resolver function (this function will run immediately).

An example I've seen that helped clarify the issue for me was that you could set a Timeout function with reject, for example:

new Promise((resolve, reject) => {
  setTimeout(()=>{reject('err msg');console.log('finished')}, 1000);
  return resolve('ret val')
})
.then((o) => console.log("RESOLVED", o))
.catch((o) => console.log("REJECTED", o));

The above could would not be possible to write with throw.

try{
  new Promise((resolve, reject) => {
    setTimeout(()=>{throw new Error('err msg')}, 1000);
    return resolve('ret val')
  })
  .then((o) => console.log("RESOLVED", o))
  .catch((o) => console.log("REJECTED", o));
}catch(o){
  console.log("IGNORED", o)
}

In the OP's small example the difference in indistinguishable but when dealing with more complicated asynchronous concept the difference between the two can be drastic.

Mine was complaining about 26. I looked in my folders and found a folder for 27, but not 26. So I modified my build.gradle file, replacing 26 with 27. compileSdkVersion, targetSdkVersion, and implementation (changed those numbers to v:7:27.02). That changed my error message. Then I added buildToolsVersion "27.0.3" to the android bracket section right under compileSdkVersion.

Now the make project button works with 0 messages.

Next up, how to actually select a module in my configuration so I can run this.

You need to add this value to the form data that is submitted to the server. You can use

If you look for sofar != totalwork you'll see ones that haven't completed, but the entries aren't removed when the operation completes so you can see a lot of history there too.

add a folder animator into res folder. (the name must be animator). Add an animator resource file. For example res/animator/fade.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:propertyName="backgroundColor"
        android:duration="1000"
        android:valueFrom="#000000"
        android:valueTo="#FFFFFF"
        android:startOffset="0"
        android:repeatCount="-1"
        android:repeatMode="reverse" />
</set>

Inside Activity java file, call this

View v = getWindow().getDecorView().findViewById(android.R.id.content);
AnimatorSet set = (AnimatorSet) AnimatorInflater.loadAnimator(this, R.animator.fade);
set.setTarget(v);
set.start();

$(window).bind("load", function() {
  // write your code here
});

Here is an example for shared memory :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>

#define SHM_SIZE 1024  /* make it a 1K shared memory segment */

int main(int argc, char *argv[])
{
    key_t key;
    int shmid;
    char *data;
    int mode;

    if (argc > 2) {
        fprintf(stderr, "usage: shmdemo [data_to_write]\n");
        exit(1);
    }

    /* make the key: */
    if ((key = ftok("hello.txt", 'R')) == -1) /*Here the file must exist */ 
{
        perror("ftok");
        exit(1);
    }

    /*  create the segment: */
    if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) {
        perror("shmget");
        exit(1);
    }

    /* attach to the segment to get a pointer to it: */
    data = shmat(shmid, NULL, 0);
    if (data == (char *)(-1)) {
        perror("shmat");
        exit(1);
    }

    /* read or modify the segment, based on the command line: */
    if (argc == 2) {
        printf("writing to segment: \"%s\"\n", argv[1]);
        strncpy(data, argv[1], SHM_SIZE);
    } else
        printf("segment contains: \"%s\"\n", data);

    /* detach from the segment: */
    if (shmdt(data) == -1) {
        perror("shmdt");
        exit(1);
    }

    return 0;
}

Steps :

1. Use ftok to convert a pathname and a project identifier to a System V IPC key

2. Use shmget which allocates a shared memory segment

3. Use shmat to attache the shared memory segment identified by shmid to the address space of the calling process

4. Do the operations on the memory area

5. Detach using shmdt

In Sequel Pro, access the User Accounts window. Note that any MySQL administration program could be substituted in place of Sequel Pro.

Add the following accounts and privileges:

AngularJS directives ng-show, ng-hide allows to display and hide a row:

   <tr ng-show="rw.isExpanded">
   </tr>

A row will be visible when rw.isExpanded == true and hidden when rw.isExpanded == false. ng-hide performs the same task but requires inverse condition.

In addition to the other answers, the following directory contains deletable system images on a Mac for Android Studio 2.3.3.

What i have also noticed is that you have to save the file as Unicode, UTF-8, no BOM in an Windows format with CRLF (Carriage Return, Line Feed). Because if you don't, the import will break. (Saying something about weird chars in the file)

Good luck :) Sid

Following is a simple working example to explain how standarization calculation works. The theory part is already well explained in other answers.

>>>import numpy as np
>>>data = [[6, 2], [4, 2], [6, 4], [8, 2]]
>>>a = np.array(data)

>>>np.std(a, axis=0)
array([1.41421356, 0.8660254 ])

>>>np.mean(a, axis=0)
array([6. , 2.5])

>>>from sklearn.preprocessing import StandardScaler
>>>scaler = StandardScaler()
>>>scaler.fit(data)
>>>print(scaler.mean_)

#Xchanged = (X-µ)/s  WHERE s is Standard Deviation and µ is mean
>>>z=scaler.transform(data)
>>>z

Calculation

As you can see in the output, mean is [6. , 2.5] and std deviation is [1.41421356, 0.8660254 ]

Data is (0,1) position is 2 Standardization = (2 - 2.5)/0.8660254 = -0.57735027

Data in (1,0) position is 4 Standardization = (4-6)/1.41421356 = -1.414

Result After Standardization

Check Mean and Std Deviation After Standardization

Note: -2.77555756e-17 is very close to 0.

This isn't a problem with your proxy. It's a problem with github (or git). It fails for me on git-1.6.0.1 on linux as well. Bug is already reported (by you no less).

Make sure to delete your pasties, they're already on google. Edit: Must've been dreaming, i guess you can't delete them. Use Gist instead?

txtPath.Text = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)+"\\\Tasks";

If You are comparing only with the date vale, then converting it to date (not datetime) will work

select id,numbers_from,created_date,amount_numbers,SMS_text 
 from Test_Table
 where 
 created_date <= convert(date,'2013-04-12',102)

This conversion is also applicable during using GetDate() function

When you execute something synchronously, you wait for it to finish before moving on to another task. When you execute something asynchronously, you can move on to another task before it finishes.

That being said, in the context of computers this translates into executing a process or task on another "thread." A thread is a series of commands (a block of code) that exists as a unit of work. The operating system can manage multiple threads and assign a thread a piece ("slice") of processor time before switching to another thread to give it a turn to do some work. At its core (pardon the pun), a processor can simply execute a command, it has no concept of doing two things at one time. The operating system simulates this by allocating slices of time to different threads.

Now, if you introduce multiple cores/processors into the mix, then things CAN actually happen at the same time. The operating system can allocate time to one thread on the first processor, then allocate the same block of time to another thread on a different processor. All of this is about allowing the operating system to manage the completion of your task while you can go on in your code and do other things.

Asynchronous programming is a complicated topic because of the semantics of how things tie together when you can do them at the same time. There are numerous articles and books on the subject; have a look!

If it works for MySQL 5.6 and 5.7.8, but fails on 5.7.11. Then it probably is a regression bug for 5.7.11.

Updating, as this is extremely old. You should, of course, use string.Join now. It didn't exist as an option at the time of writing.

Why you just not read the File line by line and add it to a StringBuffer?

After you reach end of File you can get the String from the StringBuffer.

So I know this is an older question but I think it could stand an updated answer.

Microsoft has officially released asp.net vnext and its open source and deploy-able to both Linux and Mac. Its all still pretty new but does rely on the latest builds of mono and thus currently needs you to compile the mono-framework but in time I suspect that it will be easier to access as various linux distros release updated versions of mono. This is a how to setup guide

This information may be somewhat volatile and with updates is due to change.

Update ASP.NET CORE 11/10/2017

• asp.net vnext is now known as asp.net core.
• asp.net core is being treated as a high priority in Microsoft due in part to its use with microservice architecture and docker and container technologies
• It has become much more compatible with existing .net libraries due to .net standard 2.0.
• It performs well when compared to other technology stacks such as go and node.js

Here is another approach using read. I am using this for brute search of a file by its name fragment, ignoring the "permission denied" messages.

alias loc0='{ IFS= read -r x; find . -iname "*" -print 2>/dev/null | grep $x;} <<<'

A simple example:

$ { IFS= read -r x; echo "1 $x 2 ";} <<< "a b"
1 a b 2 

Note, that this converts the argument as a string into variable(s). One could use several parameters within quotes for this, space separated:

$ { read -r x0 x1; echo "1 ${x0} 2 ${x1} 3 ";} <<< "a b"
1 a 2 b 3 

The easies way i know of is this

function stipTrailingSlash(str){
   if(srt.charAt(str.length-1) == "/"){ str = str.substr(0, str.length - 1);}
   return str
}

This will then check for a / on the end and if its there remove it if its not will return your string as it was

Just one thing that i cant comment on yet @ThiefMaster wow you dont care about memory do you lol runnign a substr just for an if?

Fixed the calucation for zero-based index on the string.

Update to angular 4.X.X, there is a new way to mark an option selected:

<select [compareWith]="byId" [(ngModel)]="selectedItem">
  <option *ngFor="let item of items" [ngValue]="item">{{item.name}}
  </option>
</select>

byId(item1: ItemModel, item2: ItemModel) {
  return item1.id === item2.id;
}

If the already posted answers aren't fast enough you'll probably have to look for a solution specific to your particular problem.

For example if these text files are logs that are only appended to and you regularly need to know the number of lines in them you could create an index. This index would contain the number of lines in the file, when the file was last modified and how large the file was then. This would allow you to recalculate the number of lines in the file by skipping over all the lines you had already seen and just reading the new lines.

Here's an alternative method that uses only the numpy package. It takes advantage of numpy's array functions, so may be faster when interpolating/extrapolating large arrays:

import numpy as np

def extrap(x, xp, yp):
    """np.interp function with linear extrapolation"""
    y = np.interp(x, xp, yp)
    y = np.where(x<xp[0], yp[0]+(x-xp[0])*(yp[0]-yp[1])/(xp[0]-xp[1]), y)
    y = np.where(x>xp[-1], yp[-1]+(x-xp[-1])*(yp[-1]-yp[-2])/(xp[-1]-xp[-2]), y)
    return y

x = np.arange(0,10)
y = np.exp(-x/3.0)
xtest = np.array((8.5,9.5))

print np.exp(-xtest/3.0)
print np.interp(xtest, x, y)
print extrap(xtest, x, y)

Edit: Mark Mikofski's suggested modification of the "extrap" function:

def extrap(x, xp, yp):
    """np.interp function with linear extrapolation"""
    y = np.interp(x, xp, yp)
    y[x < xp[0]] = yp[0] + (x[x<xp[0]]-xp[0]) * (yp[0]-yp[1]) / (xp[0]-xp[1])
    y[x > xp[-1]]= yp[-1] + (x[x>xp[-1]]-xp[-1])*(yp[-1]-yp[-2])/(xp[-1]-xp[-2])
    return y

nothing much to add,

1 - if you want to execute a query in a loop (more than 1 time), prepared statement can be faster, because of optimization that you mentioned.

2 - parameterized query is a good way to avoid SQL Injection. Parameterized querys are only available in PreparedStatement.

This took me a little while to figure out. The real key is to read that Formatter documentation.

// Get your data from wherever.
final byte[] data = getData();
// Get the digest engine.
final MessageDigest md5= MessageDigest.getInstance("MD5");
// Send your data through it.
md5.update(data);
// Parse the data as a positive BigInteger.
final BigInteger digest = new BigInteger(1,md5.digest());
// Pad the digest with blanks, 32 wide.
String hex = String.format(
    // See: http://download.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html
    // Format: %[argument_index$][flags][width]conversion
    // Conversion: 'x', 'X'  integral    The result is formatted as a hexadecimal integer
    "%1$32x",
    digest
);
// Replace the blank padding with 0s.
hex = hex.replace(" ","0");
System.out.println(hex);

I suspect the problem is because the json represents an object with the list of users as a property. Try deserializing to something like:

public class UsersResponse
{
    public List<User> Data { get; set; }
}

The <Comment> tag contains two text nodes and two <br> nodes as children.

Your xpath expression was

//*[contains(text(),'ABC')]

To break this down,

1. * is a selector that matches any element (i.e. tag) -- it returns a node-set.
2. The [] are a conditional that operates on each individual node in that node set. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
3. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
4. contains is a function that operates on a string. If it is passed a node set, the node set is converted into a string by returning the string-value of the node in the node-set that is first in document order. Hence, it can match only the first text node in your <Comment> element -- namely BLAH BLAH BLAH. Since that doesn't match, you don't get a <Comment> in your results.

You need to change this to

//*[text()[contains(.,'ABC')]]

1. * is a selector that matches any element (i.e. tag) -- it returns a node-set.
2. The outer [] are a conditional that operates on each individual node in that node set -- here it operates on each element in the document.
3. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
4. The inner [] are a conditional that operates on each node in that node set -- here each individual text node. Each individual text node is the starting point for any path in the brackets, and can also be referred to explicitly as . within the brackets. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
5. contains is a function that operates on a string. Here it is passed an individual text node (.). Since it is passed the second text node in the <Comment> tag individually, it will see the 'ABC' string and be able to match it.

Run the code either in onload event, either just before you close body tag. You try to find an element wich is not there at the moment you do it.

Notice that another issue that might be causing this is that, the "FollowSymLinks" option of a parent directory might have been mistakenly overwritten by the options of your project's directory. This was the case for me and made me pull my hair until I found out the cause!

Here's an example of such a mistake:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options Indexes # <--- NOT OK! It's overwriting the above option of the "/" directory.
        AllowOverride all
        Require all granted
</Directory>

So now if you check the Apache's log message(tail -n 50 -f /var/www/html/{the_error_log_file_of_your_site}) you'll see such an error:

Options FollowSymLinks and SymLinksIfOwnerMatch are both off, so the RewriteRule directive
is also forbidden due to its similar ability to circumvent directory restrictions

That's because Indexes in the above rules for /var/www directory is overwriting the FolowSymLinks of the / directory. So now that you know the cause, in order to fix it, you can do many things depending on your need. For instance:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options FollowSymLinks Indexes # <--- OK.
        AllowOverride all
        Require all granted
</Directory>

Or even this:

<Directory />
        Options FollowSymLinks
        AllowOverride all
        Require all denied
</Directory>

<Directory /var/www/>
        Options -Indexes # <--- OK as well! It will NOT cause an overwrite.
        AllowOverride all
        Require all granted
</Directory>

The example above will not cause the overwrite issue, because in Apache, if an option is "+" it will overwrite the "+"s only, and if it's a "-", it will overwrite the "-"s... (Don't ask me for a reference on that though, it's just my interpretation of an Apache's error message(checked through journalctl -xe) which says: Either all Options must start with + or -, or no Option may. when an option has a sign, but another one doesn't(E.g., FollowSymLinks -Indexes). So it's my personal conclusion -thus should be taken with a grain of salt- that if I've used -Indexes as the option, that will be considered as a whole distinct set of options by the Apache from the other option in the "/" which doesn't have any signs on it, and so no annoying rewrites will occur in the end, which I could successfully confirm by the above rules in a project directory of my own).

Hope that this will help you pull much less of your hair! :)

(parseFloat('2.3') + parseFloat('2.4')).toFixed(1);

its going to give you solution i suppose

As far as I know its not possible with javascript.

What you can do for every result create a screenshot, save it somewhere and point the user when clicked on save result. (I guess no of result is only 10 so not a big deal to create 10 jpeg image of results)

import time

abort_after = 5 * 60
start = time.time()

while True:
  delta = time.time() - start
  if delta >= abort_after:
    break

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

$('div').css({"-webkit-transform":"translate(100px,100px)"});?

Try the Date function. It will give you today's date in a MM/DD/YYYY format. If you're looking for today's date in the MM-DD-YYYY format try Date$. Now() also includes the current time (which you might not need). It all depends on what you need. :)

I found solution from below link.

[Text] Text doesn't wrap #1438

As @sudoPlz mentioned in comments it works with flexShrink: 1 updating this answer.

We can copy all columns from one table to another, existing table:

INSERT INTO table2 SELECT * FROM table1;

Or we can copy only the columns we want to into another, existing table:

INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1;

or SELECT * INTO BACKUP_TABLE1 FROM TABLE1

You forgot to add std:: namespace prefix to vector class name.

Passing the dataframes to concat in a dictionary, results in a multi-index dataframe from which you can easily delete the duplicates, which results in a multi-index dataframe with the differences between the dataframes:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
""")
DF2 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow
2013-11-24 Orange  8.6 Orange
2013-11-24 Apple   7.6 Green
2013-11-24 Celery 10.2 Green
2013-11-25 Apple  22.1 Red
2013-11-25 Orange  8.6 Orange""")


df1 = pd.read_table(DF1, sep='\s+')
df2 = pd.read_table(DF2, sep='\s+')
#%%
dfs_dictionary = {'DF1':df1,'DF2':df2}
df=pd.concat(dfs_dictionary)
df.drop_duplicates(keep=False)

Result:

             Date   Fruit   Num   Color
DF2 4  2013-11-25   Apple  22.1     Red
    5  2013-11-25  Orange   8.6  Orange

You can clean cache in React Native >= 0.50 and npm > 5 :

watchman watch-del-all && 
rm -rf $TMPDIR/react-native-packager-cache-* &&
rm -rf $TMPDIR/metro-bundler-cache-* && 
rm -rf node_modules/ 
&& npm cache clean --force &&
npm install && 
npm start -- --reset-cache

Apart from cleaning npm cache you might need to reset simulator or clean build etc.

This is the solution but you have to set:

echo 1 > /proc/sys/vm/overcommit_memory

Take a look at the border-collapse: separate attribute (default) and the border-spacing property.

First, you have to seperate them with border-collapse, then you can define the space between columns and rows with border-spacing .

Both of these CSS properties are actually well-supported on every browser, see here.

table     {border-collapse: separate;  border-spacing: 10px 20px;}_x000D_
_x000D_
table, _x000D_
table td,_x000D_
table th  {border: 1px solid black;}

<table>_x000D_
  <tr>_x000D_
    <td>Some text - 1</td>_x000D_
    <td>Some text - 1</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Some text - 2</td>_x000D_
    <td>Some text - 2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Some text - 3</td>_x000D_
    <td>Some text - 3</td>_x000D_
  </tr>_x000D_
</table>

You can use the SOUNDEX and related DIFFERENCE function in SQL Server to find similar names. The reference on MSDN is here.

>>> a = '&#'
>>> print a.replace('&', r'\&')
\&#
>>> print a.replace('#', r'\#')
&\#
>>> 

You want to use a 'raw' string (denoted by the 'r' prefixing the replacement string), since raw strings to not treat the backslash specially.

Try Math.log(x) / Math.log(2)

You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.

[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment

#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")

produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token

]

However, for general token pasting, try this:

/*
 * Concatenate preprocessor tokens A and B without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define PPCAT_NX(A, B) A ## B

/*
 * Concatenate preprocessor tokens A and B after macro-expanding them.
 */
#define PPCAT(A, B) PPCAT_NX(A, B)

Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.

Continuing on the theme are these macros:

/*
 * Turn A into a string literal without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define STRINGIZE_NX(A) #A

/*
 * Turn A into a string literal after macro-expanding it.
 */
#define STRINGIZE(A) STRINGIZE_NX(A)

Then,

#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"

By contrast,

STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"

#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"

I have worked alot with msaccess vba. I think you are looking for MID function

example

    dim myReturn as string
    myreturn = mid("bonjour tout le monde",9,4)

will give you back the value "tout"

when you start in cygwin, you are in your $HOME, like in unix generally, which maps to c:/cygwin/home/$YOURNAME by default. So you could put everything there.

You can also access the c: drive from cygwin through /cygdrive/c/ (e.g. /cygdrive/c/Documents anb Settings/yourname/Desktop).

Also, their "device dashboard" stats at:

http://developer.android.com/about/dashboards/index.html#Screens

can be pretty helpful. They are current and derived from Android Market visits.

Run ./gradlew build -stacktrace in Android Studio terminal. It helps you to find a file that causes this error.

You can use this code snippet:

var New1 = EmpList.OrderBy(z => z.Age).ToList();

where New1 is a List<Employee>.

EmpList is variable of a List<Employee>.

z is a variable of Employee type.

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

This is not the best way of going about solving the issue

vertical-align: middle

Adding style="position:relative;top:2px;" to the input box would move it down 2px. So depending on your font size, you can move it along.

The .map files are for js and css (and now ts too) files that have been minified. They are called SourceMaps. When you minify a file, like the angular.js file, it takes thousands of lines of pretty code and turns it into only a few lines of ugly code. Hopefully, when you are shipping your code to production, you are using the minified code instead of the full, unminified version. When your app is in production, and has an error, the sourcemap will help take your ugly file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.

Same for CSS files. Once you take a SASS or LESS file and compile it to CSS, it looks nothing like its original form. If you enable sourcemaps, then you can see the original state of the file, instead of the modified state.

So, to answer you questions in order:

• What is it for? To de-reference uglified code
• How can a developer use it? You use it for debugging a production app. In development mode you can use the full version of Angular. In production, you would use the minified version.
• Should I care about creating a js.map file? If you care about being able to debug production code easier, then yes, you should do it.
• How does it get created? It is created at build time. There are build tools that can build your .map file for you as it does other files. https://github.com/gruntjs/grunt-contrib-uglify/issues/71

I hope this makes sense.

I know I'm WAY late to this question, but figured I'd throw my snippets up here. A lot of the answers here are OK, and, as one points out, it's generally best to use feature detection rather than rely on the userAgent string. However, if you are going to go that route, I've written a complete snippet, as well as an alternate jQuery implementation to replace the depricated $.browser.

Vanilla JS

My first snippet simply adds four properties to the navigator object: browser, version, mobile, & webkit.

Here is a minor improvement to CMS's solution:

if(!String.prototype.startsWith){
    String.prototype.startsWith = function (str) {
        return !this.indexOf(str);
    }
}

"Hello World!".startsWith("He"); // true

 var data = "Hello world";
 var input = 'He';
 data.startsWith(input); // true

Checking whether the function already exists in case a future browser implements it in native code or if it is implemented by another library. For example, the Prototype Library implements this function already.

Using ! is slightly faster and more concise than === 0 though not as readable.

    import org.json.JSONObject;

    HashMap<Object, Object> map = new HashMap<>();
    String[] list={"Grader","Participant"};
    String[] list1={"Assistant","intern"};
    map.put("TeachingAssistant",list);
    map.put("Writer",list1);
    JSONObject jsonObject = new JSONObject(map);
    System.out.printf(jsonObject.toString());

    // Result: {"TeachingAssistant":["Grader","Participant"],"Writer":["Assistant","intern"]}

Use the show_source(); function of PHP. Check for more details in show_source. This is a better method I guess.

Make sure you have all the required software to run node-gyp:

• https://github.com/TooTallNate/node-gyp

You can configure version of Visual Studio used by node-gyp via an environment variable so you can avoid having to set the --msvs_version=2012 property every time you do an npm install.

Examples:

• set GYP_MSVS_VERSION=2012 for Visual Studio 2012
• set GYP_MSVS_VERSION=2013e (the 'e' stands for FREE 'express edition')

For the full list see - https://github.com/joyent/node/blob/v0.10.29/tools/gyp/pylib/gyp/MSVSVersion.py#L209-294

This is still painful for Windows users of NodeJS as it assumes you have a copy of Visual Studio installed and many end users will never have this. So I'm lobbying Joyent to the encourage them to include web sockets as part of CORE node and also to possible ship a GNU gcc compiler as part of NodeJS install so we can permanently fix this problem.

Feel free to add your vote at:

There is LIKE operator is added in Entity Framework Core 2.0:

var query = from e in _context.Employees
                    where EF.Functions.Like(e.Title, "%developer%")
                    select e;

Comparing to ... where e.Title.Contains("developer") ... it is really translated to SQL LIKE rather than CHARINDEX we see for Contains method.

DF[ ! ( ( DF$sub ==1 & DF$day==2) | ( DF$sub ==3 & DF$day==4) ) , ]   # note the ! (negation)

Or if sub is a factor as suggested by your use of quotes:

DF[ ! paste(sub,day,sep="_") %in% c("1_2", "3_4"), ]

Could also use subset:

subset(DF,  ! paste(sub,day,sep="_") %in% c("1_2", "3_4") )

(And I endorse the use of which in Dirk's answer when using "[" even though some claim it is not needed.)

Jinja 2.6 does not have the map function. So an alternate way of doing this would be:

set_fact: foo="{% for i in bar_result.results %}{{ i.ansible_facts.foo_item }}{%endfor%}"

A better and modern approach is to use ES6 Fetch API to check if an image exists or not:

fetch('https://via.placeholder.com/150', { method: 'HEAD' })
    .then(res => {
        if (res.ok) {
            console.log('Image exists.');
        } else {
            console.log('Image does not exist.');
        }
    }).catch(err => console.log('Error:', err));

Make sure you are either making the same-origin requests or CORS is enabled on the server.

I was able to get this done following more complex instructions suggested by Valentino Vranken and rao , but here is a more simple approach , for a more simple report . This will put each table on a separate sheet and name them in Excel . It doesn't seem to have an effect on other exports like PDF and Word .

First in the Tablix Properties of of your tables under General , check either Add a page break before or after , this separates the report into sheets .

Then in each table , click the table , then in the Grouping view , on the Row Groups side , select the parent group or the default row group and then in the Properties view under Group -> PageBreak set BreakLocation to None and PageName to the sheet's name .

You can use javascript for this purpose, this way:

1. first you set the CSS for the 'normal' class and for the 'active' class
2. then you give to your element the id 'MyElement'
3. and now you make your condition in JavaScript, something like the example below... (you can run it, change the value of myVar to 5 and you will see how it works)

var myVar = 4;_x000D_
_x000D_
if(myVar == 5){_x000D_
  document.getElementById("MyElement").className = "active";_x000D_
}_x000D_
else{_x000D_
  document.getElementById("MyElement").className = "normal";_x000D_
}

.active{_x000D_
  background-position : 150px 8px;_x000D_
  background-color: black;_x000D_
}_x000D_
.normal{_x000D_
  background-position : 4px 8px; _x000D_
  background-color: green;_x000D_
}_x000D_
div{_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  }

<div id="MyElement">_x000D_
  _x000D_
  </div>

I use android studio in Windows 7 and i have AVG for antivirus. The first time you launch adb, AVG prompts you to add avg.exe in antivirus vault. If you accept, then you android studio dont have access to run adb.exe. So open avg >> options >> Virus Vault >> Restore (select the adb file)

to get the text from a

<option value="1" data-sigla="AC">Acre</option>

uf = $("#selectestado option:selected").attr('data-sigla');

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

For me, and other newbies who has just contacted with Javascript,
I think that the Closeure Solution is a little kind of too confusing.

While I found that, you can easilly pass as many parameters as you want to every ajax callback using jquery.

Here are two easier solutions.

First one, which @zeroasterisk has mentioned above, example:

var $items = $('.some_class');
$.each($items, function(key, item){
    var url = 'http://request_with_params' + $(item).html();
    $.ajax({
        selfDom     : $(item),
        selfData    : 'here is my self defined data',

        url         : url,
        dataType    : 'json',
        success     : function(data, code, jqXHR){
            // in $.ajax callbacks, 
            // [this] keyword references to the options you gived to $.ajax
            // if you had not specified the context of $.ajax callbacks.
            // see http://api.jquery.com/jquery.ajax/#jQuery-ajax-settings context
            var $item = this.selfDom;
            var selfdata = this.selfData;
            $item.html( selfdata );
            ...
        } 
    });
});

Second one, pass self-defined-datas by adding them into the XHR object which exists in the whole ajax-request-response life span.

var $items = $('.some_class');
$.each($items, function(key, item){
    var url = 'http://request_with_params' + $(item).html();
    $.ajax({
        url         : url,
        dataType    : 'json',
        beforeSend  : function(XHR) {
            // ??????,???? jquery??????? XHR
            XHR.selfDom = $(item);
            XHR.selfData = 'here is my self defined data';
        },
        success     : function(data, code, jqXHR){
            // jqXHR is a superset of the browser's native XHR object
            var $item = jqXHR.selfDom;
            var selfdata = jqXHR.selfData;
            $item.html( selfdata );
            ...
        } 
    });
});

As you can see these two solutions has a drawback that : you need write a little more code every time than just write:

$.get/post (url, data, successHandler);

Read more about $.ajax : http://api.jquery.com/jquery.ajax/

You should be able to set the server.session.timeout in your application.properties file.

ref: http://docs.spring.io/spring-boot/docs/1.4.x/reference/html/common-application-properties.html

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

I was trying to do this as I wanted to use a records "title" as an id in the view but the titles had spaces.

a solution is:

record.value.delete(' ') # Foo Bar -> FooBar

here is a function that fix your problem

    public static void fixID(Connection conn, String table) {

    try {
        Statement myStmt = conn.createStatement();
        ResultSet myRs;
        int i = 1, id = 1, n = 0;
        boolean b;
        String sql;

        myRs = myStmt.executeQuery("select max(id) from " + table);
        if (myRs.next()) {
            n = myRs.getInt(1);
        }
        while (i <= n) {
            b = false;
            myRs = null;
            while (!b) {
                myRs = myStmt.executeQuery("select id from " + table + " where id=" + id);
                if (!myRs.next()) {
                    id++;
                } else {
                    b = true;
                }
            }

            sql = "UPDATE " + table + " set id =" + i + " WHERE id=" + id;
            myStmt.execute(sql);
            i++;
            id++;
        }

    } catch (SQLException e) {
        e.printStackTrace();
    }
}

You could format the dates before you add them to your array. That is how I did. I used AngularJS

//convert the date to a standard format

var dt = new Date(date);

//take only the date and month and push them to your label array

$rootScope.charts.mainChart.labels.push(dt.getDate() + "-" + (dt.getMonth() + 1));

Use this array in your chart presentation

Just for the record, there is an alternative solution that does not require javascript. It is a bit of a hack, exploiting the fact that clicking on a label sets the focus on the associated input.

You need a <label> with a proper for attribute (points to the input), optionnaly styled like a button (with bootstrap, use btn btn-default). When the user clicks the label, the dialog opens, example :

<!-- optionnal, to add a bit of style -->_x000D_
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
_x000D_
<!-- minimal setup -->_x000D_
<label for="exampleInput" class="btn btn-default">_x000D_
  Click me_x000D_
</label>_x000D_
<input type="file" id="exampleInput" style="display: none" />

// This is wrong 
categoryTitle.textColor = [UIColor colorWithRed:188 green:149 blue:88 alpha:1.0];

// This should be  
categoryTitle.textColor = [UIColor colorWithRed:188/255 green:149/255 blue:88/255 alpha:1.0];

// In the documentation, the limit of the parameters are mentioned.

colorWithRed:green:blue:alpha: documentation link

I had to look for them in C:\Users\Dell\AppData\Local\Arduino15\

I had to take help from the "date created" and "date modified" attributes to identify which libraries to delete.

But the names still show in the IDE... But it is something I can live with for now.

I use the following technique. It makes it easy to keep the column names in sync with the content:

var cursor = db.getCollection('Employees.Details').find({})

var header = []
var rows = []

var firstRow = true
cursor.forEach((doc) => 
{
    var cells = []
    
    if (firstRow) header.push("employee_number")
    cells.push(doc.EmpNum.valueOf())

    if (firstRow) header.push("name")
    cells.push(doc.FullName.valueOf())    

    if (firstRow) header.push("dob")
    cells.push(doc.DateOfBirth.valueOf())   
    
    row = cells.join(',')
    rows.push(row)    

    firstRow =  false
})

print(header.join(','))
print(rows.join('\n'))

from django.db import models

class Foo(models.Model):
    any_field = models.BooleanField(default=True)

A "JSON object" doesn't make sense : JSON is an exchange format based on the structure of Javascript object declaration.

If you want to convert your javascript object to a json string, use JSON.stringify(yourObject);

If you want to create a javascript object, simply do it like this :

var yourObject = {
          test:'test 1',
          testData: [ 
                {testName: 'do',testId:''}
          ],
          testRcd:'value'   
};

use this:

pil_image = PIL.Image.open('Image.jpg').convert('RGB') 
open_cv_image = numpy.array(pil_image) 
# Convert RGB to BGR 
open_cv_image = open_cv_image[:, :, ::-1].copy() 

You can also do it on the worksheet level captured in the worksheet's change event. If that suites your needs better. Allows for dynamic locking based on values, criteria, ect...

Private Sub Worksheet_Change(ByVal Target As Range)

    'set your criteria here
    If Target.Column = 1 Then

        'must disable events if you change the sheet as it will
        'continually trigger the change event
        Application.EnableEvents = False
        Application.Undo
        Application.EnableEvents = True

        MsgBox "You cannot do that!"
    End If
End Sub

From the documentation. The develop will not install the package but it will create a .egg-link in the deployment directory back to the project source code directory.

So it's like installing but instead of copying to the site-packages it adds a symbolic link (the .egg-link acts as a multiplatform symbolic link).

That way you can edit the source code and see the changes directly without having to reinstall every time that you make a little change. This is useful when you are the developer of that project hence the name develop. If you are just installing someone else's package you should use install

Inspired by cfeduke's answer, I made this function which uses IndexOf to find the old value in the string and then replaces it with the new value. I used this in an SSIS script processing millions of rows, and the regex-method was way slower than this.

public static string ReplaceCaseInsensitive(this string str, string oldValue, string newValue)
{
    int prevPos = 0;
    string retval = str;
    // find the first occurence of oldValue
    int pos = retval.IndexOf(oldValue, StringComparison.InvariantCultureIgnoreCase);

    while (pos > -1)
    {
        // remove oldValue from the string
        retval = retval.Remove(pos, oldValue.Length);

        // insert newValue in it's place
        retval = retval.Insert(pos, newValue);

        // check if oldValue is found further down
        prevPos = pos + newValue.Length;
        pos = retval.IndexOf(oldValue, prevPos, StringComparison.InvariantCultureIgnoreCase);
    }

    return retval;
}

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

You can use VBScript regular expression features using OLE Automation. This is way better than the overhead of creating and maintaining an assembly. Please make sure you go through the comments section to get a better modified version of the main one.

http://blogs.msdn.com/b/khen1234/archive/2005/05/11/416392.aspx

DECLARE @obj INT, @res INT, @match BIT;
DECLARE @pattern varchar(255) = '<your regex pattern goes here>';
DECLARE @matchstring varchar(8000) = '<string to search goes here>';
SET @match = 0;

-- Create a VB script component object
EXEC @res = sp_OACreate 'VBScript.RegExp', @obj OUT;

-- Apply/set the pattern to the RegEx object
EXEC @res = sp_OASetProperty @obj, 'Pattern', @pattern;

-- Set any other settings/properties here
EXEC @res = sp_OASetProperty @obj, 'IgnoreCase', 1;

-- Call the method 'Test' to find a match
EXEC @res = sp_OAMethod @obj, 'Test', @match OUT, @matchstring;

-- Don't forget to clean-up
EXEC @res = sp_OADestroy @obj;

If you get SQL Server blocked access to procedure 'sys.sp_OACreate'... error, use sp_reconfigure to enable Ole Automation Procedures. (Yes, unfortunately that is a server level change!)

Happy coding

At one time, I remember seeing the MSDN library state to use CStr() because it was faster. I do not know if this is true though.

If you do not wait for the page to be loaded you will not be able to select the element by id. This solution should work for anyone having trouble getting the code to execute

<script type="text/javascript">
window.onload = function() {
    document.getElementById("delete").onclick = function() {myFunction()};

    function myFunction() {
        //your code goes here
        alert('Alert message here');
    }
};
</script>

<a href='#' id='delete'>Delete Document</a>

The accepted solution did not work for me.

After some more research I came across this workaround, and it actually does work.

Here is the gist of it:

function showProgress() {
    var pb = document.getElementById("progressBar");
    pb.innerHTML = '<img src="./progress-bar.gif" width="200" height ="40"/>';
    pb.style.display = '';
}

and in your html:

<input type="submit" value="Submit" onclick="showProgress()" />
<div id="progressBar" style="display: none;">
    <img src="./progress-bar.gif" width="200" height ="40"/>
</div>

So when the form is submitted, the <img/> tag is inserted, and for some reason it is not affected by the ie animation issues.

Tested in Firefox, ie6, ie7 and ie8.

You entity is not correctly annotated, you must use the @javax.persistence.Entity annotation. You can use the Hibernate extension @org.hibernate.annotations.Entity to go beyond what JPA has to offer but the Hibernate annotation is not a replacement, it's a complement.

So change your code into:

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
public class Message { 
    ...  
}

Are you asking about this?

    public VariantDate(int day) : this(day, 1) {}

    public VariantDate(int day, int month) : this(day, month,1900){}

    public VariantDate(int day, int month, int year){
    this.day=day;
    this.month=month;
    this.year=year;

            // TODO Auto-generated method stub

        }

I don't see why you shouldn't be able to send html content via a post.

if you encounter any issues, you could perhaps use some kind of encoding / decoding - but I don't see that you will.

Subprocess is good but some people may like scriptine better. Scriptine has more high-level set of methods like shell.call(args), path.rename(new_name) and path.move(src,dst). Scriptine is based on subprocess and others.

Two drawbacks of scriptine:

• Current documentation level would be more comprehensive even though it is sufficient.
• Unlike subprocess, scriptine package is currently not installed by default.

     {"colour": None},
 ]

 pandas_df = pd.DataFrame.from_dict(records)
 pyspark_df = sqlContext.createDataFrame(records)

So if we wanted the rows that are not red:

pandas_df[~pandas_df["colour"].isin(["red"])]

Looking good, and in our pyspark DataFrame

pyspark_df.filter(~pyspark_df["colour"].isin(["red"])).collect()

So after some digging, I found this: https://issues.apache.org/jira/browse/SPARK-20617 So to include nothingness in our results:

pyspark_df.filter(~pyspark_df["colour"].isin(["red"]) | pyspark_df["colour"].isNull()).show()

Maybe one of the easiest solutions would be to use the x descriptor of the srcset attribute as such:

<!-- With a 80% size reduction (1/0.8=1.25) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 1.25x" />

<!-- With a 50% size reduction (1/0.5=2) -->
<img srcset="https://fr.wikipedia.org/static/images/mobile/copyright/wikipedia.png 2x" />

Simple, use array_intersect() instead:

$result = array_intersect($array1, $array2);

String time1 = "16:00:00";
String time2 = "19:00:00";

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date date1 = format.parse(time1);
Date date2 = format.parse(time2);
long difference = date2.getTime() - date1.getTime(); 

Difference is in milliseconds.

You may need to handle javax.persistence.RollbackException

Just to elaborate a bit more on Henry's answer, you can also use specific error codes, from raise_application_error and handle them accordingly on the client side. For example:

Suppose you had a PL/SQL procedure like this to check for the existence of a location record:

   PROCEDURE chk_location_exists
   (
      p_location_id IN location.gie_location_id%TYPE
   )
   AS
      l_cnt INTEGER := 0;
   BEGIN
      SELECT COUNT(*)
        INTO l_cnt
        FROM location
       WHERE gie_location_id = p_location_id;

       IF l_cnt = 0
       THEN
          raise_application_error(
             gc_entity_not_found,
             'The associated location record could not be found.');
       END IF;
   END;

The raise_application_error allows you to raise a specific error code. In your package header, you can define: gc_entity_not_found INTEGER := -20001;

If you need other error codes for other types of errors, you can define other error codes using -20002, -20003, etc.

Then on the client side, you can do something like this (this example is for C#):

/// <summary>
/// <para>Represents Oracle error number when entity is not found in database.</para>
/// </summary>
private const int OraEntityNotFoundInDB = 20001;

And you can execute your code in a try/catch

try
{
   // call the chk_location_exists SP
}
catch (Exception e)
{
    if ((e is OracleException) && (((OracleException)e).Number == OraEntityNotFoundInDB))
    {
        // create an EntityNotFoundException with message indicating that entity was not found in
        // database; use the message of the OracleException, which will indicate the table corresponding
        // to the entity which wasn't found and also the exact line in the PL/SQL code where the application
        // error was raised
        return new EntityNotFoundException(
            "A required entity was not found in the database: " + e.Message);
    }
}

I've merged the solutions of user157196 and Carter Page:

class MapUtil {

    public static <K, V extends Comparable<? super V>> Map<K, V> sortByValue( Map<K, V> map ){
        ValueComparator<K,V> bvc =  new ValueComparator<K,V>(map);
        TreeMap<K,V> sorted_map = new TreeMap<K,V>(bvc);
        sorted_map.putAll(map);
        return sorted_map;
    }

}

class ValueComparator<K, V extends Comparable<? super V>> implements Comparator<K> {

    Map<K, V> base;
    public ValueComparator(Map<K, V> base) {
        this.base = base;
    }

    public int compare(K a, K b) {
        int result = (base.get(a).compareTo(base.get(b)));
        if (result == 0) result=1;
        // returning 0 would merge keys
        return result;
    }
}

A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision.

IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).

A Double in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double object.

Thanks for the replies.

I tried the first approach, but nothing changed. Then, I tried to log the results. I just drilled down level by level, until I finally got to where the data was being displayed.

After a while I found the problem: When I was sending the response, I was converting it to a string via .toString().

I fixed that and now it works brilliantly. Sorry for the false alarm.

In case you want to utilize .then() which has a subtle difference in comparison with .done() :

return $.post(url, payload)
.then(
    function (result, textStatus, jqXHR) {
        return result;
    },
    function (jqXHR, textStatus, errorThrown) {
        return console.error(errorThrown);
    });

I could help you out with the html:

<option value="">abc</option>

instead of

<option value="4">abc</option>

to set abc as the default value.

There is two steps to extract year for all the dataframe without using method apply.

Step1

convert the column to datetime :

df['ArrivalDate']=pd.to_datetime(df['ArrivalDate'], format='%Y-%m-%d')

Step2

extract the year or the month using DatetimeIndex() method

 pd.DatetimeIndex(df['ArrivalDate']).year

In a nutshell, three easy rules to remember PECS:

1. Use the <? extends T> wildcard if you need to retrieve object of type T from a collection.
2. Use the <? super T> wildcard if you need to put objects of type T in a collection.
3. If you need to satisfy both things, well, don’t use any wildcard. As simple as that.

The problem occurs because webpack-dev-server 2.4.4 adds a host check. You can disable it by adding this to your webpack config:

 devServer: {
    compress: true,
    disableHostCheck: true,   // That solved it

 }      

EDIT: Please note, this fix is insecure.

Please see the following answer for a secure solution: https://stackoverflow.com/a/43621275/5425585

Here's a screenshot from that updated repo:

Thanks @Waylan, your comment was exactly right.

This approach works well:

gci C:\Projects *.config -recurse | ForEach {
  (Get-Content $_ | ForEach {$_ -replace "old", "new"}) | Set-Content $_ 
}

• Change "old" and "new" to their corresponding values (or use variables).
• Don't forget the parenthesis -- without which you will receive an access error.

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

Let yet add up to the answer from @Drew Noakes:

Target:

"C:\Program Files\Git\git-bash.exe" --cd=C:\GitRepo

The cd param should be one of the options how to specify the working directory.

Also notice, that I have not any --login param there: Instead, I use another extra app, dedicated just for SSH keys: Pageant (PuTTY authentication agent).

Start in:

C:\GitRepo

The same possible way, as @Drew Noakes mentioned/shown here sooner, I use it too.

Shortcut key:

Ctrl + Alt + B

Such shortcuts are another less known feature in Windows. But there is a restriction: To let the shortcut take effect, it must be placed somewhere on the User's subdirectory: The Desktop is fine.

If you do not want it visible, yet still activatable, place this .lnk file i.e. to the quick launch folder, as that dir is purposed for such shortcuts. (no matter whether displayed on the desktop) #76080 #3619355

Apache Commons has a nice implementation of Base64. You can do this as simply as:

// Encrypt data on your side using BASE64
byte[] bytesEncoded = Base64.encodeBase64(str .getBytes());
System.out.println("ecncoded value is " + new String(bytesEncoded));

// Decrypt data on other side, by processing encoded data
byte[] valueDecoded= Base64.decodeBase64(bytesEncoded );
System.out.println("Decoded value is " + new String(valueDecoded));

You can find more details about base64 encoding at Base64 encoding using Java and JavaScript.

The trim() method removes whitespace from both sides of a string.

To remove all the spaces from the string use .replace(/\s/g, "")

 this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();

This is another option:

     switch (true) {
         case (value > 100):
             //do stuff
             break;
         case (value <= 100)&&(value > 75):
             //do stuff
             break;
         case (value < 50):
            //do stuff
             break;
     }

To prevent the checkbox from taking up any space without removing it from the DOM, use hidden.

To prevent the checkbox from taking up any space and also removing it from the DOM, use display: none.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

May be you can find answer here? Equivalent of double-clickable .sh and .bat on Mac?

Usually you can create bash script for Mac OS, where you put similar commands as in batch file. For your case create bash file and put same command, but change back-slashes with regular ones.

Your file will look something like:

#! /bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;./supportlibraries/Framework_DataTable.jar;./supportlibraries/Framework_Reporting.jar;./supportlibraries/Framework_Utilities.jar;./supportlibraries/poi-3.8-20120326.jar;PATH_TO_YOUR_SELENIUM_SERVER_FOLDER/selenium-server-standalone-2.19.0.jar" allocator.testTrack

Change folders in path above to relevant one.

Then make this script executable: open terminal and navigate to folder with your script. Then change read-write-execute rights for this file running command:

chmod 755 scriptname.sh

Then you can run it like any other regular script: ./scriptname.sh

or you can run it passing file to bash:

bash scriptname.sh

Bitwise operators are operators that work on multi-bit values, but conceptually one bit at a time.

• AND is 1 only if both of its inputs are 1, otherwise it's 0.
• OR is 1 if one or both of its inputs are 1, otherwise it's 0.
• XOR is 1 only if exactly one of its inputs are 1, otherwise it's 0.
• NOT is 1 only if its input is 0, otherwise it's 0.

These can often be best shown as truth tables. Input possibilities are on the top and left, the resultant bit is one of the four (two in the case of NOT since it only has one input) values shown at the intersection of the inputs.

AND | 0 1     OR | 0 1     XOR | 0 1    NOT | 0 1
----+-----    ---+----     ----+----    ----+----
 0  | 0 0      0 | 0 1       0 | 0 1        | 1 0
 1  | 0 1      1 | 1 1       1 | 1 0

One example is if you only want the lower 4 bits of an integer, you AND it with 15 (binary 1111) so:

    201: 1100 1001
AND  15: 0000 1111
------------------
 IS   9  0000 1001

The zero bits in 15 in that case effectively act as a filter, forcing the bits in the result to be zero as well.

In addition, >> and << are often included as bitwise operators, and they "shift" a value respectively right and left by a certain number of bits, throwing away bits that roll of the end you're shifting towards, and feeding in zero bits at the other end.

So, for example:

1001 0101 >> 2 gives 0010 0101
1111 1111 << 4 gives 1111 0000

Note that the left shift in Python is unusual in that it's not using a fixed width where bits are discarded - while many languages use a fixed width based on the data type, Python simply expands the width to cater for extra bits. In order to get the discarding behaviour in Python, you can follow a left shift with a bitwise and such as in an 8-bit value shifting left four bits:

bits8 = (bits8 << 4) & 255

With that in mind, another example of bitwise operators is if you have two 4-bit values that you want to pack into an 8-bit one, you can use all three of your operators (left-shift, and and or):

packed_val = ((val1 & 15) << 4) | (val2 & 15)

• The & 15 operation will make sure that both values only have the lower 4 bits.
• The << 4 is a 4-bit shift left to move val1 into the top 4 bits of an 8-bit value.
• The | simply combines these two together.

If val1 is 7 and val2 is 4:

                val1            val2
                ====            ====
 & 15 (and)   xxxx-0111       xxxx-0100  & 15
 << 4 (left)  0111-0000           |
                  |               |
                  +-------+-------+
                          |
| (or)                0111-0100

== and != work on object identity. While the two Strings have the same value, they are actually two different objects.

use !"success".equals(statusCheck) instead.

To use the current date as the default for a date column, you will need to:

1- open table designer

2- select the column

3- go to column proprerties

4- set the value of Default value or binding propriete To (getdate())

I got around it by wrapping the supplied runnable submitted to the executor.

CompletableFuture.runAsync(() -> {
        try {
              runnable.run();

              Log.info(Concurrency.class, "runAsync", e);
        }

The count method of NSArray returns an NSUInteger, and on the 64-bit OS X platform

• NSUInteger is defined as unsigned long, and
• unsigned long is a 64-bit unsigned integer.
• int is a 32-bit integer.

So int is a "smaller" datatype than NSUInteger, therefore the compiler warning.

See also NSUInteger in the "Foundation Data Types Reference":

When building 32-bit applications, NSUInteger is a 32-bit unsigned integer. A 64-bit application treats NSUInteger as a 64-bit unsigned integer.

To fix that compiler warning, you can either declare the local count variable as

NSUInteger count;

or (if you are sure that your array will never contain more than 2^31-1 elements!), add an explicit cast:

int count = (int)[myColors count];

You'd be much better off using the same array with both lists, and creating angular filters to achieve your goal.

http://docs.angularjs.org/guide/dev_guide.templates.filters.creating_filters

Rough, untested code follows:

appModule.filter('checked', function() {
    return function(input, checked) {
        if(!input)return input;
        var output = []
        for (i in input){
            var item = input[i];
            if(item.checked == checked)output.push(item);
        }
        return output
    }
});

and the view (i added an "uncheck" button too)

<div id="AddItem">
     <h3>Add Item</h3>

    <input value="1" type="number" placeholder="1" ng-model="itemAmount">
    <input value="" type="text" placeholder="Name of Item" ng-model="itemName">

               <button ng-click="item.checked = false">uncheck item</button>

            </td>

As far as I understand

P is the set of problems which could be solved in polynomial time with a deterministic TM.

NP is the set of problems which requires a non-deterministic TM to be solved in polynomial time. This means that we can check all different combinations of variables in parallel with each instance taking polynomial time. If the problem is solvable then at least one of those parallel instances of TM would halt with "yes". This also means that if you could make a correct guess about the variables/solution then you just need to check it's validity in polynomial time.

NP-Hard is the set where problems are at least as hard as NP. This means NP-Hard problem are equally or more difficult than any problem in NP set.

1. Example of a NP-hard problem which is more difficult than NP is the halting problem.
2. Example of a NP-hard problem which is equally difficult to a NP problem is any problem in NP-Complete set (see below).

NP-Complete is the intersection set of NP and NP-Hard. A problems in NP-Complete set can be reduced to any other NP-Complete problem. That means if any of the NP-Complete problem would have an efficient solution then all of the NP-Complete problems could be solved with same solution.

How can you prove P=NP and win a US $1,000,000 prize?
If you could show that every NP problem is reducible to any other NP problem, then NP-Complete set spans over entire NP sets (definition of NP-Complete), i.e NP-Complete=NP. Also since P?NP, this means that at least one of those NP-Complete problem is solvable in polynomial time, which implies that entire NP set can be solved in polynomial time. Clearly it would conclude that P=NP. Well this is just one way to prove P=NP, there might be many other ways.

Please let me know if I made any mistake.

When you create a stored routine that has a BEGIN...END block, statements within the block are terminated by semicolon (;). But the CREATE PROCEDURE statement also needs a terminator. So it becomes ambiguous whether the semicolon within the body of the routine terminates CREATE PROCEDURE, or terminates one of the statements within the body of the procedure.

The way to resolve the ambiguity is to declare a distinct string (which must not occur within the body of the procedure) that the MySQL client recognizes as the true terminator for the CREATE PROCEDURE statement.

For Android 5.0, if you want to set it directly into a style use:

<item name="android:elevation">0dp</item>

and for Support library compatibility use:

<item name="elevation">0dp</item>

Example of style for a AppCompat light theme:

<style name="Theme.MyApp.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <!-- remove shadow below action bar -->
    <!-- <item name="android:elevation">0dp</item> -->
    <!-- Support library compatibility -->
    <item name="elevation">0dp</item>
</style>

Then apply this custom ActionBar style to you app theme:

<style name="Theme.MyApp" parent="Theme.AppCompat.Light">
    <item name="actionBarStyle">@style/Theme.MyApp.ActionBar</item>
</style>

For pre 5.0 Android, add this too to your app theme:

<!-- Remove shadow below action bar Android < 5.0 -->
<item name="android:windowContentOverlay">@null</item>

This is how I calculated the real dimensions for the first letter (you can change the method header to suit your needs, i.e. instead of char[] use String):

private void calculateTextSize(char[] text, PointF outSize) {
    // use measureText to calculate width
    float width = mPaint.measureText(text, 0, 1);

    // use height from getTextBounds()
    Rect textBounds = new Rect();
    mPaint.getTextBounds(text, 0, 1, textBounds);
    float height = textBounds.height();
    outSize.x = width;
    outSize.y = height;
}

Note that I'm using TextPaint instead of the original Paint class.
