If you want to add a photo rotate button that'll keep rotating the photo in 90 degree increments, here you go. (finalImage is a UIImage that's already been created elsewhere.)

- (void)rotatePhoto {
    UIImage *rotatedImage;

    if (finalImage.imageOrientation == UIImageOrientationRight)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationDown];
    else if (finalImage.imageOrientation == UIImageOrientationDown)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationLeft];
    else if (finalImage.imageOrientation == UIImageOrientationLeft)
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                              scale: 1.0
                                        orientation: UIImageOrientationUp];
    else
        rotatedImage = [[UIImage alloc] initWithCGImage: finalImage.CGImage
                                                     scale: 1.0
                                               orientation: UIImageOrientationRight];
    finalImage = rotatedImage;
}

For a '97 Database...

1. Open the Access 97 database in Access 2003.
2. On the Tools menu, click Database Utilities, click Convert Database, and then click to Access 2002-2003 file format.
3. Enter a name for the database, and then click Save.
4. Exit Access 2003.
5. Open the database in Access 2013.
6. On the File tab, click Save As, select Access Database (*.accdb), and then click Save As. In the Save As dialog box, click Save.

All other versions:

To convert an Access 2000 or Access 2002 - 2003 database (.mdb) to the .accdb file format, you must first open the database by using Access 2007, Access 2010, or Access 2013, and then save it in the .accdb file format.

1. Click File, and then click Open.

2. Click the Access 2000 or Access 2002 - 2003 database (.mdb) that you want to convert.

   NOTE If the Database Enhancement dialog box appears, the database is using a file format that is earlier than Access 2000. To continue, see the section Convert an Access 97 database to the .accdb format.

3. Click File, click Save As, and then click Save Database As.

4. Choose the Access file type, and then click Save As.

If any database objects are open when you click Save As, Access prompts you to close them prior to creating the copy. Click Yes to make Access close the objects, or click No to cancel the entire process. If needed, Access will also prompt you to save any changes.

1. In the Save As dialog box, type a file name in the File name box, and then click Save.

Access creates the copy of the database, and then opens the copy. Access automatically closes the original database.

Right from MS Office Documentation

Simpler approach? A little more Pythonic?

>>> ok = "0123456789abcdef"
>>> all(c in ok for c in "123456abc")
True
>>> all(c in ok for c in "hello world")
False

It certainly isn't the most efficient, but it's sure readable.

I was facing a similar issue. Actually the command is :

java -version and not java --version.

You will get output something like this:

java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

Using PuTTY's pscp.exe (which I have in an $env:path directory):

pscp -sftp -pw passwd c:\filedump\* user@host:/Outbox/
mv c:\filedump\* c:\backup\*

You could inspect the available apache2 modules:

$ ls /usr/lib/apache2/modules/

Or try to enable the php module, if you have the appropriate access:

$ a2enmod
Which module would you like to enable?
Your choices are: actions alias asis ...
... php5 proxy_ajp proxy_balancer proxy_connect ..

You probably used the "Fix Issue" option in Xcode when plugging in a new device. Old question but I believe this is the actual answer to WHY this is happening. When you install an app on a device it is signed with a specific development provisioning profile. If, for instance, you plug in another device that is not registered on your developer account Xcode will ask you to "fix the issue". When you press that the device is added and another provisioning profile is created/modified. If you try to overwrite an existing app you'll receive that error. Deleting the app and reinstalling it works since the profile has been altered. I find this often happens when a Team is set and a member plugs in a new device then Xcode "Fixes" the problem.

If you're on a linux system, once you have the file descriptor you can get a lot of information about the file using fstat()

http://linux.die.net/man/2/stat

so you might have

#include  <unistd.h> 
void main()
{
    struct stat stat;
    int fd;
    //get file descriptor
    fstat(fd, &stat);
    //the size of the file is now in stat.st_size
}

This avoids seeking to the beginning and end of the file.

ARIA (Accessible Rich Internet Applications) defines a way to make Web content and Web applications more accessible to people with disabilities.

The hidden attribute is new in HTML5 and tells browsers not to display the element. The aria-hidden property tells screen-readers if they should ignore the element. Have a look at the w3 docs for more details:

https://www.w3.org/WAI/PF/aria/states_and_properties#aria-hidden

Using these standards can make it easier for disabled people to use the web.

There is the Importing a repository with GitHub Importer

If you have a project hosted on another version control system as Mercurial, you can automatically import it to GitHub using the GitHub Importer tool.

1. In the upper-right corner of any page, click , and then click Import repository.
2. Under "Your old repository's clone URL", type the URL of the project you want to import.
3. Choose your user account or an organization to own the repository, then type a name for the repository on GitHub.
4. Specify whether the new repository should be public or private.
   • Public repositories are visible to any user on GitHub, so you can benefit from GitHub's collaborative community.
   • Public or private repository radio buttonsPrivate repositories are only available to the repository owner, as well as any collaborators you choose to share with.
5. Review the information you entered, then click Begin import.

You'll receive an email when the repository has been completely imported.

1. https://help.github.com/categories/importing-your-projects-to-github
2. https://help.github.com/articles/importing-a-repository-with-github-importer/

Correct syntax looks like this. See MSDN.

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p

  ON p.vTreasuryId COLLATE Latin1_General_CI_AS = f.RFC COLLATE Latin1_General_CI_AS 

This should work for you

 public class MyActivity extends Activity {

    protected ProgressDialog mProgressDialog;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        populateTable();
    }

    private void populateTable() {
        mProgressDialog = ProgressDialog.show(this, "Please wait","Long operation starts...", true);
        new Thread() {
            @Override
            public void run() {

                doLongOperation();
                try {

                    // code runs in a thread
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            mProgressDialog.dismiss();
                        }
                    });
                } catch (final Exception ex) {
                    Log.i("---","Exception in thread");
                }
            }
        }.start();

    }

    /** fake operation for testing purpose */
    protected void doLongOperation() {
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
        }

    }
}

You don't have to set either of them. PYTHONPATH can be set to point to additional directories with private libraries in them. If PYTHONHOME is not set, Python defaults to using the directory where python.exe was found, so that dir should be in PATH.

Use ON DUPLICATE KEY UPDATE ...,
Negative : because the UPDATE uses resources for the second action.

Use INSERT IGNORE ...,
Negative : MySQL will not show any errors if something goes wrong, so you cannot handle the errors. Use it only if you don’t care about the query.

unsigned char takes only positive values: 0 to 255 while signed char takes positive and negative values: -128 to +127.

I have a one-liner answer (this example gives you 999 lines of data and one header row per file)

I believe +%s is seconds since epoch. It's timezone invariant.

The evaluation of condition resulted in an NA. The if conditional must have either a TRUE or FALSE result.

if (NA) {}
## Error in if (NA) { : missing value where TRUE/FALSE needed

This can happen accidentally as the results of calculations:

if(TRUE && sqrt(-1)) {}
## Error in if (TRUE && sqrt(-1)) { : missing value where TRUE/FALSE needed

To test whether an object is missing use is.na(x) rather than x == NA.

See also the related errors:

Error in if/while (condition) { : argument is of length zero

Error in if/while (condition) : argument is not interpretable as logical

if (NULL) {}
## Error in if (NULL) { : argument is of length zero

if ("not logical") {}
## Error: argument is not interpretable as logical

if (c(TRUE, FALSE)) {}
## Warning message:
## the condition has length > 1 and only the first element will be used

@echo off

on the first "set countfiles" the 10 you see is the amount it will loop the echo hi is the thing you want to loop

This question is very general and there are a couple of assumptions I'll make to simplify it a bit. We'll assume that you want to update your master branch.

If you haven't made any changes locally, you can use git pull to bring down any new commits and add them to your master.

git pull origin master

If you have made changes, and you want to avoid adding a new merge commit, use git pull --rebase.

git pull --rebase origin master

git pull --rebase will work even if you haven't made changes and is probably your best call.

$var = 'abcdef';
if(isset($var))
{
   if (strlen($var) > 0);
   {
      //do something, string length greater than zero
   }
   else
   {
     //do something else, string length 0 or less
   }
}

This is a simple example. Hope it helps.

edit: added isset in the event a variable isn't defined like above, it would cause an error, checking to see if its first set at the least will help remove some headache down the road.

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!

with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

Starting from tonight nightly build of 4.6/Neon, the Eclipse Platform includes a way to increase/decrease font size on text editors using Ctrl+ and Ctrl- (on Windows or Linux, Cmd= and Cmd- on Mac OS X) : https://www.eclipse.org/eclipse/news/4.6/M4/#text-zoom-commands . The implementation is shipped with any product using a recent build of the platform, and is more reliable that the one in the alternative plugins mentioned above. It will be more widely available within weeks, when the IDE packages for Neon M4 will be available, and it will be part of the public Neon release in June 2016.

You can open a command prompt and do a

route print

and see your current routing table.

You can modify it by

route add    d.d.d.d mask m.m.m.m g.g.g.g 
route delete d.d.d.d mask m.m.m.m g.g.g.g 
route change d.d.d.d mask m.m.m.m g.g.g.g

these seem to work

I run a ping d.d.d.d -t change the route and it changes. (my test involved routing to a dead route and the ping stopped)

Booleans in python are subclass of integer. Constructor of booleans is bool. bool class inherits from int class.

 issubclass(bool,int) // will return True
 isinstance(True,bool) , isinstance(False,bool) //they both True

True and False are singleton objects. they will retain same memory address throughout the lifetime of your app. When you type True, python memory manager will check its address and will pull the value '1'. for False its value is '0'.

Comparisons of any boolean expression to True or False can be performed using either is (identity) or == (equality) operator.

int(True) == 1
int(False) == 0

But note that True and '1' are not the same objects. You can check:

 id(True) == id(1) // will return False

you can also easily see that

  True > False // returns true cause 1>0

any integer operation can work with the booleans.

  True + True + True =3 

All objects in python have an associated truth value. Every object has True value except:

• None

• False

• 0 in any numeric type (0,0.0,0+0j etc)

• empty sequences (list, tuple, string)

• empty mapping types (dictionary, set, etc)

• custom classes that implement __bool__ or __len__ method that returns False or 0.

every class in python has truth values defined by a special instance method:

 __bool__(self)   OR
 __len__

When you call bool(x) python will actually execute

 x.__bool__() 

if instance x does not have this method, then it will execute

 x.__len__()

if this does not exist, by default value is True.

For Example for int class we can define bool as below:

  def __bool__(self):
      return self != 0

for bool(100), 100 !=0 will return True. So

bool(100) == True

you can easily check that bool(0) will be False. with this for instances of int class only 0 will return False.

another example= bool([1,2,3])

[1,2,3] has no __bool__() method defined but it has __len__() and since its length is greater than 0, it will return True. Now you can see why empty lists return False.

I think the docs explain the difference and usage of these two functions pretty well:

newFixedThreadPool

Creates a thread pool that reuses a fixed number of threads operating off a shared unbounded queue. At any point, at most nThreads threads will be active processing tasks. If additional tasks are submitted when all threads are active, they will wait in the queue until a thread is available. If any thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks. The threads in the pool will exist until it is explicitly shutdown.

newCachedThreadPool

Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available. These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks. Calls to execute will reuse previously constructed threads if available. If no existing thread is available, a new thread will be created and added to the pool. Threads that have not been used for sixty seconds are terminated and removed from the cache. Thus, a pool that remains idle for long enough will not consume any resources. Note that pools with similar properties but different details (for example, timeout parameters) may be created using ThreadPoolExecutor constructors.

In terms of resources, the newFixedThreadPool will keep all the threads running until they are explicitly terminated. In the newCachedThreadPool Threads that have not been used for sixty seconds are terminated and removed from the cache.

Given this, the resource consumption will depend very much in the situation. For instance, If you have a huge number of long running tasks I would suggest the FixedThreadPool. As for the CachedThreadPool, the docs say that "These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks".

What about simply

    if (condition) { code if condition = true };

run github that you downloaded, click tools and options symbol(top right), click about github for windows and then open the debug log. under DIAGNOSTICS look for Git Executable Exists:

Here is another implementation of this solution:

using System.Net;

///
/// Checks the file exists or not.
///
/// The URL of the remote file.
/// True : If the file exits, False if file not exists
private bool RemoteFileExists(string url)
{
    try
    {
        //Creating the HttpWebRequest
        HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
        //Setting the Request method HEAD, you can also use GET too.
        request.Method = "HEAD";
        //Getting the Web Response.
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        //Returns TRUE if the Status code == 200
        response.Close();
        return (response.StatusCode == HttpStatusCode.OK);
    }
    catch
    {
        //Any exception will returns false.
        return false;
    }
}

I came across this solution from @jbabey while trying to solve a similar problem. With a little modification, I got it right. In my case, the object keys are numbers (489) and strings ("489"). Hence to solve this, each key is parse. The following code works:

var array = {"nR": 22, "nH": 7, "totB": "2761", "nSR": 16, "htRb": "91981"}
var parskey = 0;
for (var key in array) {
    parskey = parseInt(array[key]);
    sum += parskey;
};
return(sum);

here's a solution using a stack. No recursion.

def flatten_nested_dict(nested):
    stack = list(nested.items())
    ans = {}
    while stack:
        key, val = stack.pop()
        if isinstance(val, dict):
            for sub_key, sub_val in val.items():
                stack.append((f"{key}_{sub_key}", sub_val))
        else:
            ans[key] = val
    return ans

Instead of appending element you can just do.

 document.getElementById("p").textContent += " this has just been added";

document.getElementById("p").textContent += " this has just been added";

<p id ="p">This is some text</p>

In Xcode 5.1

Enable Done Button

• In Attributes Inspector for the UITextField in Storyboard find the field "Return Key" and select "Done"

Hide Keyboard when Done is pressed

• In Storyboard make your ViewController the delegate for the UITextField

• Add this method to your ViewController

  -(BOOL)textFieldShouldReturn:(UITextField *)textField
  {
      [textField resignFirstResponder];
      return YES;
  }
  

In your example parts of your passed-in URL are not URL encoded (for example the colon should be %3A, the forward slashes should be %2F). It looks like you have encoded the parameters to your parameter URL, but not the parameter URL itself. Try encoding it as well. You can use encodeURIComponent.

You should move it:

Directory.Move(source, destination);

git difftool -d HEAD filename.txt

This shows a comparison using VI slit window in the terminal.

I understand you want to display using HTMl but you can also open the PDF file using php by pointing out the path and the browser will render it in a few simple steps

<?php
$your_file_name = "url_here";

//Content type and this case its a PDF
header("Content-type: application/pdf");

header("Content-Length: " . filesize($your_file_name )); 

//Display the file
readfile($your_file_name );
?>

Actually SELECT ... INTO not only creates the table but will fail if it already exists, so basically the only time you would use it is when the table you are inserting to does not exists.

In regards to your EDIT:

I personally mainly use SELECT ... INTO when I am creating a temp table. That to me is the main use. However I also use it when creating new tables with many columns with similar structures to other tables and then edit it in order to save time.

In my case, changin screen resolution from WVGA720 to WSVGA works for me.

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

The graphicx package provides the command \resizebox{width}{height}{object}:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\hrule
%%%
\makeatletter%
\setlength{\@tempdima}{\the\columnwidth}% the, well columnwidth
\settowidth{\@tempdimb}{(\ref{Equ:TooLong})}% the width of the "(1)"
\addtolength{\@tempdima}{-\the\@tempdimb}% which cannot be used for the math
\addtolength{\@tempdima}{-1em}%
% There is probably some variable giving the required minimal distance
% between math and label, but because I do not know it I used 1em instead.
\addtolength{\@tempdima}{-1pt}% distance must be greater than "1em"
\xdef\Equ@width{\the\@tempdima}% space remaining for math
\begin{equation}%
\resizebox{\Equ@width}{!}{$\displaystyle{% to get everything inside "big"

I had the case where the name of the function varied according to a variable (var 'x' in this case) added to the functions name. This works:

if ( typeof window['afunction_'+x] === 'function' ) { window['afunction_'+x](); } 

If number could be None or a number, and you wanted to include 0, filter on None instead:

if number is not None:

If number can be any number of types, test for the type; you can test for just int or a combination of types with a tuple:

if isinstance(number, int):  # it is an integer
if isinstance(number, (int, float)):  # it is an integer or a float

or perhaps:

from numbers import Number

if isinstance(number, Number):

to allow for integers, floats, complex numbers, Decimal and Fraction objects.

This isn't the exact answer you are looking for but it was a solution that i needed on my project and hope this helps someone. This will list 1 to n row items separated by commas. Group_Concat makes this possible in MySQL.

select
cemetery.cemetery_id as "Cemetery_ID",
GROUP_CONCAT(distinct(names.name)) as "Cemetery_Name",
cemetery.latitude as Latitude,
cemetery.longitude as Longitude,
c.Contact_Info,
d.Direction_Type,
d.Directions

    from cemetery
    left join cemetery_names on cemetery.cemetery_id = cemetery_names.cemetery_id 
    left join names on cemetery_names.name_id = names.name_id 
    left join cemetery_contact on cemetery.cemetery_id = cemetery_contact.cemetery_id 

    left join 
    (
        select 
            cemetery_contact.cemetery_id as cID,
            group_concat(contacts.name, char(32), phone.number) as Contact_Info

                from cemetery_contact
                left join contacts on cemetery_contact.contact_id = contacts.contact_id 
                left join phone on cemetery_contact.contact_id = phone.contact_id 

            group by cID
    )
    as c on c.cID = cemetery.cemetery_id


    left join
    (
        select 
            cemetery_id as dID, 
            group_concat(direction_type.direction_type) as Direction_Type,
            group_concat(directions.value , char(13), char(9)) as Directions

                from directions
                left join direction_type on directions.type = direction_type.direction_type_id

            group by dID


    )
    as d on d.dID  = cemetery.cemetery_id

group by Cemetery_ID

This cemetery has two common names so the names are listed in different rows connected by a single id but two name ids and the query produces something like this

    CemeteryID     Cemetery_Name             Latitude
    1                    Appleton,Sulpher Springs   35.4276242832293

I used below regex to get that result also when its finished by a \

(\\[^\\]+)\\?$

[Regex Demo]

You should check for permissions in the following way (as described here Android permissions):

int result = ContextCompat.checkSelfPermission(getContext(), Manifest.permission.READ_PHONE_STATE);

then, compare your result to either:

result == PackageManager.PERMISSION_DENIED

or:

result == PackageManager.PERMISSION_GRANTED

By the way, you can use next code in you event handler:

switch(e.EventType)
{
  case SerialData.Chars:
  {
    // means you receives something
    break;
  }
  case SerialData.Eof:
  {
    // means receiving ended
    break;
  }
}

I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

Every example here shows a solution using the FileReader. It is convenient if you do not need to care about a file encoding. If you use some other languages than english, encoding is quite important. Imagine you have file with this text

Príliš žlutoucký kun
úpel dábelské ódy

and the file uses windows-1250 format. If you use FileReader you will get this result:

P??li? ?lu?ou?k? k??
?p?l ??belsk? ?dy

So in this case you would need to specify encoding as Cp1250 (Windows Eastern European) but the FileReader doesn't allow you to do so. In this case you should use InputStreamReader on a FileInputStream.

Example:

String encoding = "Cp1250";
File file = new File("foo.txt");

if (file.exists()) {
    try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), encoding))) {
        String line = null;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}
else {
    System.out.println("file doesn't exist");
}

In case you want to read the file character after character do not use BufferedReader.

try (InputStreamReader isr = new InputStreamReader(new FileInputStream(file), encoding)) {
    int data = isr.read();
    while (data != -1) {
        System.out.print((char) data);
        data = isr.read();
    }
} catch (IOException e) {
    e.printStackTrace();
}

Try this; bear in mind that JavaScript months are 0-indexed, whilst days are 1-indexed.

var date = new Date('2010-10-11T00:00:00+05:30');_x000D_
    alert(((date.getMonth() > 8) ? (date.getMonth() + 1) : ('0' + (date.getMonth() + 1))) + '/' + ((date.getDate() > 9) ? date.getDate() : ('0' + date.getDate())) + '/' + date.getFullYear());

If you want to do this in a robust way that works for every possible command line argument (values with spaces, values with newlines, values with literal quote characters, non-printable values, values with glob characters, etc), it gets a bit more interesting.

To write to a file, given an array of arguments:

printf '%s\0' "${arguments[@]}" >file

...replace with "argument one", "argument two", etc. as appropriate.

To read from that file and use its contents (in bash, ksh93, or another recent shell with arrays):

declare -a args=()
while IFS='' read -r -d '' item; do
  args+=( "$item" )
done <file
run_your_command "${args[@]}"

To read from that file and use its contents (in a shell without arrays; note that this will overwrite your local command-line argument list, and is thus best done inside of a function, such that you're overwriting the function's arguments and not the global list):

set --
while IFS='' read -r -d '' item; do
  set -- "$@" "$item"
done <file
run_your_command "$@"

Note that -d (allowing a different end-of-line delimiter to be used) is a non-POSIX extension, and a shell without arrays may also not support it. Should that be the case, you may need to use a non-shell language to transform the NUL-delimited content into an eval-safe form:

quoted_list() {
  ## Works with either Python 2.x or 3.x
  python -c '
import sys, pipes, shlex
quote = pipes.quote if hasattr(pipes, "quote") else shlex.quote
print(" ".join([quote(s) for s in sys.stdin.read().split("\0")][:-1]))
  '
}

eval "set -- $(quoted_list <file)"
run_your_command "$@"

You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build --build-arg arg=2.3 ..

For iOS 9 beta 3,4 users. Since the option to view profiles is not viewable do the following from Xcode.

1. Open Xcode 7.
2. Go to window, devices.
3. Select your device.
4. Delete all of the profiles loaded on the device.
5. Delete the old app on your device.
6. Clean and rebuild the app to your device.

On iOS 9.1+ n iOS 9.2+ go to Settings -> General -> Device Management -> press the Profile -> Press Trust.

This will also restore the staging directory:

git stash apply --index

Services are quite complicated sometimes.

When you start a service from an activity (or your process), the service is essentially on the same process.

quoting from the developer notes

Most confusion about the Service class actually revolves around what it is not:

A Service is not a separate process. The Service object itself does not imply it is running in its own process; unless otherwise specified, it runs in the same process as the application it is part of.

A Service is not a thread. It is not a means itself to do work off of the main thread (to avoid Application Not Responding errors).

So, what this means is, if the user swipes the app away from the recent tasks it will delete your process(this includes all your activities etc). Now, lets take three scenarios.

First where the service does not have a foreground notification.

In this case your process is killed along with your service.

Second where the service has a foreground notification

In this case the service is not killed and neither is the process

Third scenario If the service does not have a foreground notification, it can still keep running if the app is closed. We can do this by making the service run in a different process. (However, I've heard some people say that it may not work. left to you to try it out yourself)

you can create a service in a separate process by including the below attribute in your manifest.

android:process=":yourService"

or

android:process="yourService" process name must begin with lower case.

quoting from developer notes

If the name assigned to this attribute begins with a colon (':'), a new process, private to the application, is created when it's needed and the service runs in that process. If the process name begins with a lowercase character, the service will run in a global process of that name, provided that it has permission to do so. This allows components in different applications to share a process, reducing resource usage.

this is what I have gathered, if anyone is an expert, please do correct me if I'm wrong :)

This worked for me, source: here

I had this error and it wasn't related with the DB constrains (at least in my case). I have an .xsd file with a GetRecord query that returns a group of records. One of the columns of that table was "nvarchar(512)" and in the middle of the project I needed to changed it to "nvarchar(MAX)".

Everything worked fine until the user entered more than 512 on that field and we begin to get the famous error message "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."

Solution: Check all the MaxLength property of the columns in your DataTable.

The column that I changed from "nvarchar(512)" to "nvarchar(MAX)" still had the 512 value on the MaxLength property so I changed to "-1" and it works!!.

After trying all the other solutions posted here (Skype, updates to C++ Redistributable), I found that another process was using port 80. The culprit was Microsoft Internet Information Server (IIS). You can stop the service from the command line on Windows 7/Vista:

net stop was /y

Or set the service to not start automatically by going to Services: click Start, click Control Panel, click Performance and Maintenance, click Administrative Tools, and then double-click Services. There, locate "WAS Service" and "World Wide Web Publication Service" and set them to manual or deactivate them completely.

Then restart the WAMP server.

More info: http://www.sitepoint.com/unblock-port-80-on-windows-run-apache/

You can define your versionName and versionCode in your module's build.gradle file like this :

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    .... //Other Configuration
}

I've found all solutions above can produce a false positive if a package is installed and then removed yet the installation package remains on the system.

To replicate: Install package apt-get install curl
Remove package apt-get remove curl

Now test above answers.

The following command seems to solve this condition:
dpkg-query -W -f='${Status}\n' curl | head -n1 | awk '{print $3;}' | grep -q '^installed$'

This will result in a definitive installed or not-installed

Check Below Codes :

1. SynchonousRequest

Swift 1.2

    let urlPath: String = "YOUR_URL_HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSURLRequest = NSURLRequest(URL: url)
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var dataVal: NSData =  NSURLConnection.sendSynchronousRequest(request1, returningResponse: response, error:nil)!
    var err: NSError
    println(response)
    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary
    println("Synchronous\(jsonResult)")

Swift 2.0 +

            print(response)
            do {
                if let jsonResult = try NSJSONSerialization.JSONObjectWithData(dataVal, options: []) as? NSDictionary {
                    print("Synchronous\(jsonResult)")
                }

Unity supports:
1. UnityScript(Is known as Javascript but includes more functionality for the Unity game engine. I think this could be very easy to learn)
2. Boo (No experience)
3. C# (I prefer this as it is useful to learn and you will be able to use this outside of unity as well. I also think it is easy to get used to)

Since value is the last entry, you can do:

metrics.sort_by(&:last)

The for loop iterates over the elements of the array, not its indexes. Suppose you have a list ar = [2, 4, 6]:

When you iterate over it with for i in ar: the values of i will be 2, 4 and 6. So, when you try to access ar[i] for the first value, it might work (as the last position of the list is 2, a[2] equals 6), but not for the latter values, as a[4] does not exist.

If you intend to use indexes anyhow, try using for index, value in enumerate(ar):, then theSum = theSum + ar[index] should work just fine.

I suggest you use curses.h or ncurses.h these implement keyboard management routines including getch(). You have several options to change the behavior of getch (i.e. wait for keypress or not).

$(...)[index]      // gives you the DOM element at index
$(...).get(index)  // gives you the DOM element at index
$(...).eq(index)   // gives you the jQuery object of element at index

DOM objects don't have css function, use the last...

$('ul li').eq(index).css({'background-color':'#343434'});

docs:

.get(index) Returns: Element

• Description: Retrieve the DOM elements matched by the jQuery object.
• See: https://api.jquery.com/get/

.eq(index) Returns: jQuery

• Description: Reduce the set of matched elements to the one at the specified index.
• See: https://api.jquery.com/eq/

I had the idea of simply copy the source code from android.support.v4.app.FragmentPagerAdpater into a custom class named CustumFragmentPagerAdapter. This gave me the chance to modify the instantiateItem(...) so that every time it is called, it removes / destroys the currently attached fragment before it adds the new fragment received from getItem() method.

Simply modify the instantiateItem(...) in the following way:

@Override
public Object instantiateItem(ViewGroup container, int position) {
    if (mCurTransaction == null) {
        mCurTransaction = mFragmentManager.beginTransaction();
    }
    final long itemId = getItemId(position);

    // Do we already have this fragment?
    String name = makeFragmentName(container.getId(), itemId);
    Fragment fragment = mFragmentManager.findFragmentByTag(name);

    // remove / destroy current fragment
    if (fragment != null) {
        mCurTransaction.remove(fragment);

I'm new to NHibernate, and my problem was that I used a different session to query my object than I did to save it. So the saving session didn't know about the object.

It seems obvious, but from reading the previous answers I was looking everywhere for 2 objects, not 2 sessions.

Use LayoutParams (as explained already). However be careful which LayoutParams to choose. According to https://stackoverflow.com/a/11971553/3184778 "you need to use the one that relates to the PARENT of the view you're working on, not the actual view"

If for example the TextView is inside a TableRow, then you need to use TableRow.LayoutParams instead of RelativeLayout or LinearLayout

If you are using jaxrs or any other, then there will be a class called mediatype.User interceptor before sending the request and compare it against this.

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

This program will prints all the classes with its physical path. use can simply copy this to any JSP if you need to analyse the class loading from any web/application server.

import java.lang.reflect.Field;
import java.util.Vector;

public class TestMain {

    public static void main(String[] args) {
        Field f;
        try {
            f = ClassLoader.class.getDeclaredField("classes");
            f.setAccessible(true);
            ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
            Vector<Class> classes =  (Vector<Class>) f.get(classLoader);

            for(Class cls : classes){
                java.net.URL location = cls.getResource('/' + cls.getName().replace('.',
                '/') + ".class");
                System.out.println("<p>"+location +"<p/>");
            }
        } catch (Exception e) {

            e.printStackTrace();
        }
    }
}

If you have anaconda, you can just install desired version and conda will automatically downgrade the current package for you.

For example:

conda install tensorflow=1.1

You can do like this:

    TimeZone tz = TimeZone.getDefault();
    int offset = tz.getRawOffset();

    String timeZone = String.format("%s%02d%02d", offset >= 0 ? "+" : "-", offset / 3600000, (offset / 60000) % 60);

If you provide your JVM the Spring profile there should be no problems:

java -Dspring.profiles.active=development -jar yourApplication.jar 

Also see Spring-Documentation:

http://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html

69.5 Set the active Spring profiles

The Spring Environment has an API for this, but normally you would set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE). E.g. launch your application with a -D argument (remember to put it before the main class or jar archive):

$ java -jar -Dspring.profiles.active=production demo-0.0.1-SNAPSHOT.jar

In Spring Boot you can also set the active profile in application.properties, e.g.

spring.profiles.active=production

A value set this way is replaced by the System property or environment variable setting, but not by the SpringApplicationBuilder.profiles() method. Thus the latter Java API can be used to augment the profiles without changing the defaults.

See Chapter 25, Profiles in the ‘Spring Boot features’ section for more information.

It's possible to create an httpserver that provides basic support for J2EE servlets with just the JDK and the servlet api in a just a few lines of code.

I've found this very useful for unit testing servlets, as it starts much faster than other lightweight containers (we use jetty for production).

Most very lightweight httpservers do not provide support for servlets, but we need them, so I thought I'd share.

The below example provides basic servlet support, or throws and UnsupportedOperationException for stuff not yet implemented. It uses the com.sun.net.httpserver.HttpServer for basic http support.

Using ios_base::sync_with_stdio(false); is sufficient to decouple the C and C++ streams. You can find a discussion of this in Standard C++ IOStreams and Locales, by Langer and Kreft. They note that how this works is implementation-defined.

The cin.tie(NULL) call seems to be requesting a decoupling between the activities on cin and cout. I can't explain why using this with the other optimization should cause a crash. As noted, the link you supplied is bad, so no speculation here.

Installing cordova version 5.0 helps me:

npm install -g [email protected]

You can just add the number to the cell with the date.

so if A1: 12/3/2012 and A2: =A1+7 then A2 would display 12/10/2012

you could connect all the data you need from the file to a single string, and in the excel sheet seperate it with text to column. here is an example i did for same issue, enjoy:

Sub CP()
Dim ToolFile As String

Cells(3, 2).Select

For i = 0 To 5
    r = ActiveCell.Row
    ToolFile = Cells(r, 7).Value
    On Error Resume Next
    ActiveCell.Value = CP_getdatta(ToolFile)

    'seperate data by "-"
    Selection.TextToColumns Destination:=Range("C3"), DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, _
        Semicolon:=False, Comma:=False, Space:=False, Other:=True, OtherChar _
        :="-", FieldInfo:=Array(Array(1, 1), Array(2, 1)), TrailingMinusNumbers:=True

Cells(r + 1, 2).Select
Next


End Sub

Function CP_getdatta(ToolFile As String) As String
    Workbooks.Open Filename:=ToolFile, UpdateLinks:=False, ReadOnly:=True

    Range("A56000").Select
    Selection.End(xlUp).Select
    x = CStr(ActiveCell.Value)
    ActiveCell.Offset(0, 20).Select
    Selection.End(xlToLeft).Select
    While IsNumeric(ActiveCell.Value) = False
        ActiveCell.Offset(0, -1).Select
    Wend
    ' combine data to 1 string
    CP_getdatta = CStr(x & "-" & ActiveCell.Value)
    ActiveWindow.Close False

End Function

Based on @ofer.sheffer answer this command will mass rename and append the current date to the filename. ie "file.txt" becomes "20180329 - file.txt" for all files in the current folder

for %a in (*.*) do ren "%a" "%date:~-4,4%%date:~-7,2%%date:~-10,2% - %a"

I'm late to this party, but for any future C folks on Windows, Visual Studio targets C90 instead of C99, which is what you'd get on *nix. I am currently targeting C99 on Windows by using Sublime Text 2 in tandem with Cygwin.

If all you are trying to do is get the value out of the hashmap itself, you can do something like the following:

for (Object key : map.keySet()) {
    Object value = map.get(key);
    //TODO: this
}

Or, you can iterate over the entries of a map, if that is what you are interested in:

for (Map.Entry<Object, Object> entry : map.entrySet()) {
    Object key = entry.getKey();
    Object value = entry.getValue();
    //TODO: other cool stuff
}

As a community, we might be able to give you better/more appropriate answers if we had some idea why you needed the indexes or what you thought the indexes could do for you.

When you pass a pointer by a non-const reference, you are telling the compiler that you are going to modify that pointer's value. Your code does not do that, but the compiler thinks that it does, or plans to do it in the future.

To fix this error, either declare x constant

// This tells the compiler that you are not planning to modify the pointer
// passed by reference
void test(float * const &x){
    *x = 1000;
}

or make a variable to which you assign a pointer to nKByte before calling test:

float nKByte = 100.0;
// If "test()" decides to modify `x`, the modification will be reflected in nKBytePtr
float *nKBytePtr = &nKByte;
test(nKBytePtr);

Ranges from -9,223,372,036,854,775,808 to +9,223,372,036,854,775,807.

It will start from -9,223,372,036,854,775,808

Long.MIN_VALUE.

The only way I'm aware of is building CSV list and then passing it as string. Then, on SP side, just split it and do whatever you need.

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:

http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http

810    style = "body { background-color: white; color: black; font-family: "
811        "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812        "hr { border: 0; border-bottom: 1px dashed; }\n";

E.g., try this:

font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;

Java's Scanner class does not have a built in method to read from a Scanner character-by-character.

http://java.sun.com/javase/6/docs/api/java/util/Scanner.html

However, it should still be possible to fetch individual characters from the Scanner as follows:

Scanner sc:

char c = sc.findInLine(".").charAt(0);

And you could use it to fetch each character in your scanner like this:

while(sc.hasNext()){
    char c = sc.findInLine(".").charAt(0);
    System.out.println(c); //to print out every char in the scanner
}

The findInLine() method searches through your scanner and returns the first String that matches the regular expression you give it.

Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"

To change the size of a button called button1 you simple call

button1.config( height = WHATEVER, width = WHATEVER2 )

If you know what size you want at initialization these options can be added to the constructor.

button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100) 

From my notes:

http://maps.google.com/maps?q=37.4185N+122.08774W+(label)&ll=37.419731,-122.088715&spn=0.004250,0.011579&t=h&iwloc=A&hl=en

Which parses like this:

    q=latN+lonW+(label)     location of teardrop

    t=k             keyhole (satelite map)
    t=h             hybrid

    ll=lat,-lon     center of map
    spn=w.w,h.h     span of map, degrees

iwloc has something to do with the info window. hl is obviously language.

Try using the WHERE clause:

SELECT column1 FROM table WHERE Isnumeric(column1);

Use Layout inflater method in your button click. it will change your current .xml to targeted .xml file. Google for layout inflater code.

Generics can be defined using Wrapper classes only. If you don't want to define using Wrapper types, you may use the Raw definition as below

@SuppressWarnings("rawtypes")
public HashMap buildMap(String letters)
{
    HashMap checkSum = new HashMap();

    for ( int i = 0; i < letters.length(); ++i )
    {
       checkSum.put(letters.charAt(i), primes[i]);
    }
    return checkSum;
}

Or define the HashMap using wrapper types, and store the primitive types. The primitive values will be promoted to their wrapper types.

public HashMap<Character, Integer> buildMap(String letters)
{
  HashMap<Character, Integer> checkSum = new HashMap<Character, Integer>();

  for ( int i = 0; i < letters.length(); ++i )
  {
    checkSum.put(letters.charAt(i), primes[i]);
  }
  return checkSum;
}

Try using OPENDATASOURCE The syntax is like this:

select * from OPENDATASOURCE ('SQLNCLI', 'Data Source=192.168.6.69;Initial Catalog=AnotherDatabase;Persist Security Info=True;User ID=sa;Password=AnotherDBPassword;MultipleActiveResultSets=true;' ).HumanResources.Department.MyTable    

What do you mean by "not always reliable"? If the system succeeds in setting your socket non non-blocking, it will be non-blocking. Socket operations will return EWOULDBLOCK if they would block need to block (e.g. if the output buffer is full and you're calling send/write too often).

This forum thread has a few good points when working with non-blocking calls.

Have you googled about it - insert update delete access vb.net, there are lots of reference about this.

Insert Update Delete Navigation & Searching In Access Database Using VB.NET

• Create Visual Basic 2010 Project: VB-Access
• Assume that, we have a database file named data.mdb
• Place the data.mdb file into ..\bin\Debug\ folder (Where the project executable file (.exe) is placed)

what could be the easier way to connect and manipulate the DB?
Use OleDBConnection class to make connection with DB

is it by using MS ACCESS 2003 or MS ACCESS 2007?
you can use any you want to use or your client will use on their machine.

it seems that you want to find some example of opereations fo the database. Here is an example of Access 2010 for your reference:

Example code snippet:

As it is said, a picture is worth 1000 words. I say: some code is better than 1000 words. Here's the source code of HashMap. Get method:

/**
     * Implements Map.get and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @return the node, or null if none
     */
    final Node<K,V> getNode(int hash, Object key) {
        Node<K,V>[] tab; Node<K,V> first, e; int n; K k;
        if ((tab = table) != null && (n = tab.length) > 0 &&
            (first = tab[(n - 1) & hash]) != null) {
            if (first.hash == hash && // always check first node
                ((k = first.key) == key || (key != null && key.equals(k))))
                return first;
            if ((e = first.next) != null) {
                if (first instanceof TreeNode)
                    return ((TreeNode<K,V>)first).getTreeNode(hash, key);
                do {
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        return e;
                } while ((e = e.next) != null);
            }
        }
        return null;
    }

So it becomes clear that hash is used to find the "bucket" and the first element is always checked in that bucket. If not, then equals of the key is used to find the actual element in the linked list.

Let's see the put() method:

  /**
     * Implements Map.put and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @param value the value to put
     * @param onlyIfAbsent if true, don't change existing value
     * @param evict if false, the table is in creation mode.
     * @return previous value, or null if none
     */
    final V putVal(int hash, K key, V value, boolean onlyIfAbsent,
                   boolean evict) {
        Node<K,V>[] tab; Node<K,V> p; int n, i;
        if ((tab = table) == null || (n = tab.length) == 0)
            n = (tab = resize()).length;
        if ((p = tab[i = (n - 1) & hash]) == null)
            tab[i] = newNode(hash, key, value, null);
        else {
            Node<K,V> e; K k;
            if (p.hash == hash &&
                ((k = p.key) == key || (key != null && key.equals(k))))
                e = p;
            else if (p instanceof TreeNode)
                e = ((TreeNode<K,V>)p).putTreeVal(this, tab, hash, key, value);
            else {
                for (int binCount = 0; ; ++binCount) {
                    if ((e = p.next) == null) {
                        p.next = newNode(hash, key, value, null);
                        if (binCount >= TREEIFY_THRESHOLD - 1) // -1 for 1st
                            treeifyBin(tab, hash);
                        break;
                    }
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        break;
                    p = e;
                }
            }
            if (e != null) { // existing mapping for key
                V oldValue = e.value;
                if (!onlyIfAbsent || oldValue == null)
                    e.value = value;
                afterNodeAccess(e);
                return oldValue;
            }
        }
        ++modCount;
        if (++size > threshold)
            resize();
        afterNodeInsertion(evict);
        return null;
    }

It's slightly more complicated, but it becomes clear that the new element is put in the tab at the position calculated based on hash:

i = (n - 1) & hash here i is the index where the new element will be put (or it is the "bucket"). n is the size of the tab array (array of "buckets").

First, it is tried to be put as the first element of in that "bucket". If there is already an element, then append a new node to the list.

html, body {
    min-height: 100%;
}

Will do the trick.

By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

There are some great ways do achieve a very good and scalable full background image.

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

Don't use exceptions for flow control. Use DateTime.TryParse and DateTime.TryParseExact. Personally I prefer TryParseExact with a specific format, but I guess there are times when TryParse is better. Example use based on your original code:

DateTime value;
if (!DateTime.TryParse(startDateTextBox.Text, out value))
{
    startDateTextox.Text = DateTime.Today.ToShortDateString();
}

Reasons for preferring this approach:

• Clearer code (it says what it wants to do)
• Better performance than catching and swallowing exceptions
• This doesn't catch exceptions inappropriately - e.g. OutOfMemoryException, ThreadInterruptedException. (Your current code could be fixed to avoid this by just catching the relevant exception, but using TryParse would still be better.)

Please refer to this http://technet.microsoft.com/en-us/library/bb490982.aspx which explains what you can do with command output.

You should consider creating a timestamp from that date witk mktime()

eg:

$date = explode('/', $_POST['date']);
$time = mktime(0,0,0,$date[0],$date[1],$date[2]);
$mysqldate = date( 'Y-m-d H:i:s', $time );

Here's how I "automate" Dropping connected users in Oracle database:

# A shell script to Drop a Database Schema, forcing off any Connected Sessions (for example, before an Import) 
# Warning! With great power comes great responsibility.
# It is often advisable to take an Export before Dropping a Schema

if [ "$1" = "" ] 
then
    echo "Which Schema?"
    read schema
else
    echo "Are you sure? (y/n)"
    read reply
    [ ! $reply = y ] && return 1
    schema=$1
fi

sqlplus / as sysdba <<EOF
set echo on
alter user $schema account lock;
-- Exterminate all sessions!
begin     
  for x in ( select sid, serial# from v\$session where username=upper('$schema') )
  loop  
   execute immediate ( 'alter system kill session '''|| x.Sid || ',' || x.Serial# || ''' immediate' );  
  end loop;  
  dbms_lock.sleep( seconds => 2 ); -- Prevent ORA-01940: cannot drop a user that is currently connected
end;
/
drop user $schema cascade;
quit
EOF

What worked for me is:

• make sure java path is available:

$ which java
/usr/bin/java

• then in etc/netbeans.conf make sure netbeans_jdkhome is commented out
• in Finder go to /bin/ click on netbeans (terminal icon)

You would expect ./netbeans --jdkhome=/usr/bin/java to work, but it doesn't for some reason.

Try Using:

utf8_decode() and utf8_encode

set @latitude=53.754842;
set @longitude=-2.708077;
set @radius=20;

set @lng_min = @longitude - @radius/abs(cos(radians(@latitude))*69);
set @lng_max = @longitude + @radius/abs(cos(radians(@latitude))*69);
set @lat_min = @latitude - (@radius/69);
set @lat_max = @latitude + (@radius/69);

SELECT * FROM postcode
WHERE (longitude BETWEEN @lng_min AND @lng_max)
AND (latitude BETWEEN @lat_min and @lat_max);

It will focus with mouse point

$("#TextBox").focus();

Try this:

webBrowser1.DocumentText =
    "<html><body>Please enter your name:<br/>" +
    "<input type='text' name='userName'/><br/>" +
    "<a href='http://www.microsoft.com'>continue</a>" +
    "</body></html>";

As hinted at in one of the above answers, you won't get an XMLRootElement on your root element if in the XSD its type is defined as a named type, since that named type could be used elsewhere in your XSD. Try mking it an anonymous type, i.e. instead of:

<xsd:element name="myRootElement" type="MyRootElementType" />

<xsd:complexType name="MyRootElementType">
...
</xsd:complexType>

you would have:

<xsd:element name="myRootElement">
    <xsd:complexType>
    ...
    <xsd:complexType>
</xsd:element>

You have to explicitly cast the string types to the same in order to concatenate them, In your case you may solve the issue by simply addig an 'N' in front of 'SomeText' (N'SomeText'). If that doesn't work, try Cast('SomeText' as nvarchar(8)).

It is possible to play a local video file.

<input type="file" accept="video/*"/>
<video controls autoplay></video>

When a file is selected via the input element:

1. 'change' event is fired
2. Get the first File object from the input.files FileList
3. Make an object URL that points to the File object
4. Set the object URL to the video.src property

5. Lean back and watch :)

Old answer

requires no 3rd party gems

Person.where(
    Person.where(:name => "John").where(:lastname => "Smith")
      .where_values.reduce(:or)
)

There is the solution with Kotlin :

given(myObject.myCall()).willAnswer {
    throw IOException("Ooops")
}

Where given comes from

import org.mockito.BDDMockito.given

Never mind -- I'm an idiot. I just needed <xsl:value-of select="/root/Image/node()"/>

Actually I don't see any nulls:

given:

static void Main()
        {
            string[] testArray = new string[]
            {
                "aa",
                "ab",
                "ac",
                "ad",
                "ab",
                "af"
            };

            Array.Sort(testArray, StringComparer.InvariantCulture);

            Array.ForEach(testArray, x => Console.WriteLine(x));
        }

I obtained:

delete from t
where id in (1, 4, 6, 7)

JavaScript perfectly supports date difference out of the box

https://jsfiddle.net/b9chris/v5twbe3h/

var msMinute = 60*1000, 
    msDay = 60*60*24*1000,
    a = new Date(2012, 2, 12, 23, 59, 59),
    b = new Date("2013 march 12");


console.log(Math.floor((b - a) / msDay) + ' full days between'); // 364
console.log(Math.floor(((b - a) % msDay) / msMinute) + ' full minutes between'); // 0

Now some pitfalls. Try this:

console.log(a - 10); // 1331614798990
console.log(a + 10); // mixed string

So if you have risk of adding a number and Date, convert Date to number directly.

console.log(a.getTime() - 10); // 1331614798990
console.log(a.getTime() + 10); // 1331614799010

My fist example demonstrates the power of Date object but it actually appears to be a time bomb

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

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

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

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

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

EDIT

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

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

e.g.

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

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

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

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

A way to be able to use {% break %} or {% continue %} is to write TokenParsers for them.

I did it for the {% break %} token in the code below. You can, without much modifications, do the same thing for the {% continue %}.

• AppBundle\Twig\AppExtension.php:

  namespace AppBundle\Twig;
  
  class AppExtension extends \Twig_Extension
  {
      function getTokenParsers() {
          return array(
              new BreakToken(),
          );
      }
  
      public function getName()
      {
          return 'app_extension';
      }
  }
  

• AppBundle\Twig\BreakToken.php:

  namespace AppBundle\Twig;
  
  class BreakToken extends \Twig_TokenParser
  {
      public function parse(\Twig_Token $token)
      {
          $stream = $this->parser->getStream();
          $stream->expect(\Twig_Token::BLOCK_END_TYPE);
  
          // Trick to check if we are currently in a loop.
          $currentForLoop = 0;
  
          for ($i = 1; true; $i++) {
              try {
                  // if we look before the beginning of the stream
                  // the stream will throw a \Twig_Error_Syntax
                  $token = $stream->look(-$i);
              } catch (\Twig_Error_Syntax $e) {
                  break;
              }
  
              if ($token->test(\Twig_Token::NAME_TYPE, 'for')) {
                  $currentForLoop++;
              } else if ($token->test(\Twig_Token::NAME_TYPE, 'endfor')) {
                  $currentForLoop--;
              }
          }
  
  
          if ($currentForLoop < 1) {
              throw new \Twig_Error_Syntax(
                  'Break tag is only allowed in \'for\' loops.',
                  $stream->getCurrent()->getLine(),
                  $stream->getSourceContext()->getName()
              );
          }
  
          return new BreakNode();
      }
  
      public function getTag()
      {
          return 'break';
      }
  }
  

• AppBundle\Twig\BreakNode.php:

  namespace AppBundle\Twig;
  
  class BreakNode extends \Twig_Node
  {
      public function compile(\Twig_Compiler $compiler)
      {
          $compiler
              ->write("break;\n")
          ;
      }
  }
  

Then you can simply use {% break %} to get out of loops like this:

{% for post in posts %}
    {% if post.id == 10 %}
        {% break %}
    {% endif %}
    <h2>{{ post.heading }}</h2>
{% endfor %}

To go even further, you may write token parsers for {% continue X %} and {% break X %} (where X is an integer >= 1) to get out/continue multiple loops like in PHP.

Assuming you use the declarative style (i.e. ORM classes), it is pretty easy:

query = db_session.query(User.id, User.name).filter(User.id.in_([123,456]))
results = query.all()

db_session is your database session here, while User is the ORM class with __tablename__ equal to "users".

• ^ matches position just before the first character of the string
• $ matches position just after the last character of the string
• . matches a single character. Does not matter what character it is, except newline
• * matches preceding match zero or more times

So, ^.*$ means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.

Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones and Matthew's last name is Jones. The pattern ^Matt.*Jones$ will match Matthew's last name is Jones. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.

Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.

I can offer you some general algorithms...

• O(1): Accessing an element in an array (i.e. int i = a[9])
• O(n log n): quick or mergesort (On average)
• O(log n): Binary search

These would be the gut responses as this sounds like homework/interview kind of question. If you are looking for something more concrete it's a little harder as the public in general would have no idea of the underlying implementation (Sparing open source of course) of a popular application, nor does the concept in general apply to an "application"

Just in case if you can't change HTML. Very primitive but short & works. (It will empty the parent div hence the child divs will be removed)

$('#one').text('Hi I am replace');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="one">_x000D_
  <div class="first"></div>_x000D_
  "Hi I am text"_x000D_
  <div class="second"></div>_x000D_
  <div class="third"></div>_x000D_
</div>

It turns out the compiler version I was using did not match the compiled version done with the coreset.o.

One was 32bit the other was 64bit. I'll leave this up in case anyone else runs into a similar problem.

ffmpeg \
  -i input_1.mp4 \
  -i input_2.mp4 \
  -filter_complex '[0:v]pad=iw*2:ih[int];[int][1:v]overlay=W/2:0[vid]' \
  -map [vid] \
  -c:v libx264 \

I've always wondered how costly it is to always assume that invoke is required...

private void OnCoolEvent(CoolObjectEventArgs e)
{
  BeginInvoke((o,e) => /*do work here*/,this, e);
}

I like to avoid raising a new exception while handling an old one. It makes the error messages confusing to read.

For example, in my code, I originally wrote

try:
    return tuple.__getitem__(self, i)(key)
except IndexError:
    raise KeyError(key)

And I got this message.

>>> During handling of above exception, another exception occurred.

I wanted this:

try:
    return tuple.__getitem__(self, i)(key)
except IndexError:
    pass
raise KeyError(key)

It doesn't affect how exceptions are handled. In either block of code, a KeyError would have been caught. This is merely an issue of getting style points.

As ghills had already mentioned

inp = int(input("Enter a number:"))

n = 0
for i in str(inp):
    n = n + int(i);
    print n

When you are looping through something, keyword is "IN", just always think of it as a list of something. You cannot loop through a plain integer. Therefore, it is not iterable.

The simple way to create Current TimeStamp. like below,

func generateCurrentTimeStamp () -> String {
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy_MM_dd_hh_mm_ss"
    return (formatter.string(from: Date()) as NSString) as String
}

d.keys()[0] to get the individual key.

Update:- @AlejoBernardin , am not sure why you said it didn't work. here I checked and it worked. import collections

prices  = collections.OrderedDict((

    ("banana", 4),
    ("apple", 2),
    ("orange", 1.5),
    ("pear", 3),
))
prices.keys()[0]

'banana'

JavaScript does not have such declarations. It would be:

var cubes = ...

regardless

But you can do:

for(var i = 0; i < cubes.length; i++)
{
  for(var j = 0; j < cubes[i].length; j++)
  {

  }
}

Note that JavaScript allows jagged arrays, like:

[
  [1, 2, 3],
  [1, 2, 3, 4]
]

since arrays can contain any type of object, including an array of arbitrary length.

As noted by MDC:

"for..in should not be used to iterate over an Array where index order is important"

If you use your original syntax, there is no guarantee the elements will be visited in numeric order.

If you want the second highest number you can use

=LARGE(E4:E9;2)

although that doesn't account for duplicates so you could get the same result as the Max

If you want the largest number that is smaller than the maximum number you can use this version

=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)

Browsers are getting smarter. Today your browser (depending on the version) might skip the image loading if it can determine it's not useful.

The image has a display:none style but its size may be read by the script. Chrome v68.0 does not load images if the parent is hidden.

You may check it there : http://jsfiddle.net/tnk3j08s/

You could also have checked it by looking at the "network" tab of your browser's developer tools.

Note that if the browser is on a small CPU computer, not having to render the image (and layout the page) will make the whole rendering operation faster but I doubt this is something that really makes sense today.

If you want to prevent the image from loading you may simply not add the IMG element to your document (or set the IMG src attribute to "data:" or "about:blank").

Boolean is threadsafe, so you can consider this factor as well along with all other listed in answers

I use the free file searching program Everything, search for *.sql files across my C: drive, and then sort by Last Modified, and then browse by the date I think it was probably last executed.

It usually brings up loads of autorecovery files from a variety of locations. And you don't have to worry where the latest version of SSMS/VS is saving the backup files this version.

public String convertImageToBase64(String filePath) {
    byte[] fileContent = new byte[0];
    String base64encoded = null;
    try {
        fileContent = FileUtils.readFileToByteArray(new File(filePath));
    } catch (IOException e) {
        log.error("Error reading file: {}", filePath);
    }
    try {
        base64encoded = Base64.getEncoder().encodeToString(fileContent);
    } catch (Exception e) {
        log.error("Error encoding the image to base64", e);
    }
    return base64encoded;
}

Excerpted from the documentation for Percent Strings at http://ruby-doc.org/core/doc/syntax/literals_rdoc.html#label-Percent+Strings:

Besides %(...) which creates a String, the % may create other types of object. As with strings, an uppercase letter allows interpolation and escaped characters while a lowercase letter disables them.

These are the types of percent strings in ruby:
...
%w: Array of Strings

You can use an OFFSET in a LIMIT command:

SELECT * FROM aTable LIMIT 1 OFFSET 99

in case your table has 100 rows this return the last row without relying on a primary_key

This can now also happen in Node.js as of version 14.

It happens when you declare your package type as module in your package.json. If you do this, certain CommonJS variables can't be used, including require.

To fix this, remove "type": "module" from your package.json and make sure you don't have any files ending with .mjs.

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

If you are using tox to run tests on multiple versions of Python, you may need to install the Python dev libraries for each version of Python you are testing on.

sudo apt-get install python2.6-dev 
sudo apt-get install python2.7-dev 
etc.

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

Might not be so related to the issue above. However if you are looking for a way to serialize Java object as string, this could come in hand

package pt.iol.security;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
import org.apache.commons.codec.binary.Base64;

public class ObjectUtil {

    static final Base64 base64 = new Base64();

    public static String serializeObjectToString(Object object) throws IOException {
        try (
                ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();
                GZIPOutputStream gzipOutputStream = new GZIPOutputStream(arrayOutputStream);
                ObjectOutputStream objectOutputStream = new ObjectOutputStream(gzipOutputStream);) {
            objectOutputStream.writeObject(object);
            objectOutputStream.flush();
            return new String(base64.encode(arrayOutputStream.toByteArray()));
        }
    }

    public static Object deserializeObjectFromString(String objectString) throws IOException, ClassNotFoundException {
        try (
                ByteArrayInputStream arrayInputStream = new ByteArrayInputStream(base64.decode(objectString));
                GZIPInputStream gzipInputStream = new GZIPInputStream(arrayInputStream);
                ObjectInputStream objectInputStream = new ObjectInputStream(gzipInputStream)) {
            return objectInputStream.readObject();
        }
    }
}

Another strange behavior in my case I have a table without any primary key.EF itself creates composite primary key using all columns i.e.:

 <Key>
        <PropertyRef Name="ID" />
        <PropertyRef Name="No" />
       <PropertyRef Name="Code" />
   </Key>

And whenever I do any update operation it throws this exception:

The property 'Code' is part of the object's key information and cannot be modified.

Solution: remove table from EF diagram and go to your DB add primary key on table that is creating problem and re-add table to EF diagram it's all now it will have single key i.e.

<Key>
        <PropertyRef Name="ID" />
</Key>

The Main Differences:

1. Scanner

• A simple text scanner which can parse primitive types and strings using regular expressions.
• A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods.

Example

 String input = "1 fish 2 fish red fish blue fish";
 Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
 System.out.println(s.nextInt());
 System.out.println(s.nextInt());
 System.out.println(s.next());
 System.out.println(s.next());
 s.close(); 

prints the following output:

 1
 2
 red
 blue 

The same output can be generated with this code, which uses a regular expression to parse all four tokens at once:

 String input = "1 fish 2 fish red fish blue fish";

 Scanner s = new Scanner(input);
 s.findInLine("(\\d+) fish (\\d+) fish (\\w+) fish (\\w+)");
 MatchResult result = s.match();
 for (int i=1; i<=result.groupCount(); i++)
     System.out.println(result.group(i));
 s.close(); `

2. BufferedReader:

   • Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.

   • The buffer size may be specified, or the default size may be used. The default is large enough for most purposes.

In general, each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders. For example,

BufferedReader in
   = new BufferedReader(new FileReader("foo.in"));

will buffer the input from the specified file. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. Programs that use DataInputStreams for textual input can be localized by replacing each DataInputStream with an appropriate BufferedReader.

You can use the javascript in the second link provided by Ravi Khakhkhar or you are going to have to perform some string manipulation to convert your orginal string (as some of the special characters in your original format aren't being recognised as valid delimeters) but once you do that, you can use "new"

Use negative lookaround: (?!pattern)

Positive lookarounds can be used to assert that a pattern matches. Negative lookarounds is the opposite: it's used to assert that a pattern DOES NOT match. Some flavor supports assertions; some puts limitations on lookbehind, etc.

Assuming there is a column named business:

SELECT Business, COUNT(*) FROM eventsTable GROUP BY Business

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]", "[email protected]" };

var result = (from t2 in test2
              where test1.Any(t => t2.Contains(t)) == false
              select t2);

If query form is what you want to use, this is legible and more or less as "performant" as this could be.

What i mean is that what you are trying to do is an O(N*M) algorithm, that is, you have to traverse N items and compare them against M values. What you want is to traverse the first list only once, and compare against the other list just as many times as needed (worst case is when the email is valid since it has to compare against every black listed domain).

from t2 in test we loop the email list once.

test1.Any(t => t2.Contains(t)) == false we compare with the blacklist and when we found one match return (hence not comparing against the whole list if is not needed)

select t2 keep the ones that are clean.

So this is what I would use.

Tried everything mentioned (browser preferences, hsts, etc.) but nothing worked for me.

I solved it by adding a trailing .localhost to the host aliases.

Like this:

127.0.0.1    myproject.localhost
127.0.0.1    dev.project.localhost

the best way if you use Spring Boot is :

1/ Create a ServletInitializer extends SpringBootServletInitializer Class . With method configure which run your Application Class

2/ Generate always a maven install WAR file

3/ With this artefact you can even :

    . start application from war file with java -jar file.war

    . put your war file in your favorite Web App server (like tomcat, ...)

If you download the repository with git clone <repo_url> -b <branch> (only cloning certaing branch), you should modify the <repo_name>/.git/config file. Replace or modify the line that references the fetch target of the [remote "origin"] section to let the command git fetch --all discover all branches:

[remote "origin"]
        url = <repo_git_url>
        fetch = +refs/heads/master:refs/remotes/origin/master

Be sure to set the fetch parameter point to /heads/master.

Care with git fetch --all because this will fetch all, so may take a long time.

I found that even after following all the steps above, I was still getting errors saying that my Maven dependencies (i.e. pom.xml) were pointing to jar files that didn't exist.

Viewing the errors in the Problems tab, for some reason these were still pointing to the old location of my repository. This was probably because I'd changed the location of my Maven repository since creating the workspace and project.

This can be easily solved by deleting the project from the Eclipse workspace, and re-adding it again through Package Explorer -> R/Click -> Import... -> Existing Projects.

In C and C++, \n is a concept, \r is a character, and \r\n is (almost always) a portability bug.

Think of an old teletype. The print head is positioned on some line and in some column. When you send a printable character to the teletype, it prints the character at the current position and moves the head to the next column. (This is conceptually the same as a typewriter, except that typewriters typically moved the paper with respect to the print head.)

When you wanted to finish the current line and start on the next line, you had to do two separate steps:

1. move the print head back to the beginning of the line, then
2. move it down to the next line.

ASCII encodes these actions as two distinct control characters:

• \x0D (CR) moves the print head back to the beginning of the line. (Unicode encodes this as U+000D CARRIAGE RETURN.)
• \x0A (LF) moves the print head down to the next line. (Unicode encodes this as U+000A LINE FEED.)

In the days of teletypes and early technology printers, people actually took advantage of the fact that these were two separate operations. By sending a CR without following it by a LF, you could print over the line you already printed. This allowed effects like accents, bold type, and underlining. Some systems overprinted several times to prevent passwords from being visible in hardcopy. On early serial CRT terminals, CR was one of the ways to control the cursor position in order to update text already on the screen.

But most of the time, you actually just wanted to go to the next line. Rather than requiring the pair of control characters, some systems allowed just one or the other. For example:

• Unix variants (including modern versions of Mac) use just a LF character to indicate a newline.
• Old (pre-OSX) Macintosh files used just a CR character to indicate a newline.
• VMS, CP/M, DOS, Windows, and many network protocols still expect both: CR LF.
• Old IBM systems that used EBCDIC standardized on NL--a character that doesn't even exist in the ASCII character set. In Unicode, NL is U+0085 NEXT LINE, but the actual EBCDIC value is 0x15.

Why did different systems choose different methods? Simply because there was no universal standard. Where your keyboard probably says "Enter", older keyboards used to say "Return", which was short for Carriage Return. In fact, on a serial terminal, pressing Return actually sends the CR character. If you were writing a text editor, it would be tempting to just use that character as it came in from the terminal. Perhaps that's why the older Macs used just CR.

Now that we have standards, there are more ways to represent line breaks. Although extremely rare in the wild, Unicode has new characters like:

• U+2028 LINE SEPARATOR
• U+2029 PARAGRAPH SEPARATOR

Even before Unicode came along, programmers wanted simple ways to represent some of the most useful control codes without worrying about the underlying character set. C has several escape sequences for representing control codes:

• \a (for alert) which rings the teletype bell or makes the terminal beep
• \f (for form feed) which moves to the beginning of the next page
• \t (for tab) which moves the print head to the next horizontal tab position

(This list is intentionally incomplete.)

This mapping happens at compile-time--the compiler sees \a and puts whatever magic value is used to ring the bell.

Notice that most of these mnemonics have direct correlations to ASCII control codes. For example, \a would map to 0x07 BEL. A compiler could be written for a system that used something other than ASCII for the host character set (e.g., EBCDIC). Most of the control codes that had specific mnemonics could be mapped to control codes in other character sets.

Huzzah! Portability!

Well, almost. In C, I could write printf("\aHello, World!"); which rings the bell (or beeps) and outputs a message. But if I wanted to then print something on the next line, I'd still need to know what the host platform requires to move to the next line of output. CR LF? CR? LF? NL? Something else? So much for portability.

C has two modes for I/O: binary and text. In binary mode, whatever data is sent gets transmitted as-is. But in text mode, there's a run-time translation that converts a special character to whatever the host platform needs for a new line (and vice versa).

Great, so what's the special character?

Well, that's implementation dependent, too, but there's an implementation-independent way to specify it: \n. It's typically called the "newline character".

This is a subtle but important point: \n is mapped at compile time to an implementation-defined character value which (in text mode) is then mapped again at run time to the actual character (or sequence of characters) required by the underlying platform to move to the next line.

\n is different than all the other backslash literals because there are two mappings involved. This two-step mapping makes \n significantly different than even \r, which is simply a compile-time mapping to CR (or the most similar control code in whatever the underlying character set is).

This trips up many C and C++ programmers. If you were to poll 100 of them, at least 99 will tell you that \n means line feed. This is not entirely true. Most (perhaps all) C and C++ implementations use LF as the magic intermediate value for \n, but that's an implementation detail. It's feasible for a compiler to use a different value. In fact, if the host character set is not a superset of ASCII (e.g., if it's EBCDIC), then \n will almost certainly not be LF.

So, in C and C++:

• \r is literally a carriage return.
• \n is a magic value that gets translated (in text mode) at run-time to/from the host platform's newline semantics.
• \r\n is almost always a portability bug. In text mode, this gets translated to CR followed by the platform's newline sequence--probably not what's intended. In binary mode, this gets translated to CR followed by some magic value that might not be LF--possibly not what's intended.
• \x0A is the most portable way to indicate an ASCII LF, but you only want to do that in binary mode. Most text-mode implementations will treat that like \n.

Angularjs already has filter option to do this , https://docs.angularjs.org/api/ng/filter/filter

I found the solution for it by analyzing the data packets using wireshark. What I found is that while making a secure connection, android was falling back to SSLv3 from TLSv1 . It is a bug in android versions < 4.4 , and it can be solved by removing the SSLv3 protocol from Enabled Protocols list. I made a custom socketFactory class called NoSSLv3SocketFactory.java. Use this to make a socketfactory.

Use this class like this while connecting :

SSLContext sslcontext = SSLContext.getInstance("TLSv1");
sslcontext.init(null, null, null);
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());

HttpsURLConnection.setDefaultSSLSocketFactory(NoSSLv3Factory);
l_connection = (HttpsURLConnection) l_url.openConnection();
l_connection.connect();

UPDATE :

Now, correct solution would be to install a newer security provider using Google Play Services:

    ProviderInstaller.installIfNeeded(getApplicationContext());

This effectively gives your app access to a newer version of OpenSSL and Java Security Provider, which includes support for TLSv1.2 in SSLEngine. Once the new provider is installed, you can create an SSLEngine which supports SSLv3, TLSv1, TLSv1.1 and TLSv1.2 the usual way:

    SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
    sslContext.init(null, null, null);
    SSLEngine engine = sslContext.createSSLEngine();

Or you can restrict the enabled protocols using engine.setEnabledProtocols.

Don't forget to add the following dependency (check the latest version here):

implementation 'com.google.android.gms:play-services-auth:17.0.0'

For more info, checkout this link.

This is a solution and a model for possible solutions. Use Moment.js in your client to format dates, convert to unix time.

 $scope.startDate.unix()

Setup your route parameters to be long.

[Route("{startDate:long?}")]
public async Task<object[]> Get(long? startDate)
{
    DateTime? sDate = new DateTime();

        if (startDate != null)
        {
            sDate = new DateTime().FromUnixTime(startDate.Value); 
        }
        else
        {
            sDate = null;
        }
         ... your code here!
  }

Create an extension method for Unix time. Unix DateTime Method

You don't tend to execute the make file itself, rather you execute make, giving it the make file as an argument:

make -f pax.mk

If your make file is actually one of the standard names (like makefile or Makefile), you don't even need to specify it. It'll be picked up by default (if you have more than one of these standard names in your build directory, you better look up the make man page to see which takes precedence).

It's the directory where java was run from, where you started the JVM. Does not have to be within the user's home directory. It can be anywhere where the user has permission to run java.

So if you cd into /somedir, then run your program, user.dir will be /somedir.

A different property, user.home, refers to the user directory. As in /Users/myuser or /home/myuser or C:\Users\myuser.

See here for a list of system properties and their descriptions.

You don't need regex to split a string on whitespace:

In [1]: text = '''WYATT    - Ranked # 855 with    0.006   %
   ...: XAVIER   - Ranked # 587 with    0.013   %
   ...: YONG     - Ranked # 921 with    0.006   %
   ...: YOUNG    - Ranked # 807 with    0.007   %'''

In [2]: print '\n'.join(line.split()[0] for line in text.split('\n'))
WYATT
XAVIER
YONG
YOUNG

You can use C style string formatting:

"%d:%d:d" % (hours, minutes, seconds)

See here, especially: https://web.archive.org/web/20120415173443/http://diveintopython3.ep.io/strings.html

It may help to use a different constructor for Uri.

If you have the server name

string server = "http://www.myserver.com";

and have a relative Uri path to append to it, e.g.

string relativePath = "sites/files/images/picture.png"

When creating a Uri from these two I get the "format could not be determined" exception unless I use the constructor with the UriKind argument, i.e.

// this works, because the protocol is included in the string
Uri serverUri = new Uri(server);

// needs UriKind arg, or UriFormatException is thrown
Uri relativeUri = new Uri(relativePath, UriKind.Relative); 

// Uri(Uri, Uri) is the preferred constructor in this case
Uri fullUri = new Uri(serverUri, relativeUri);

The using keyword defines the scope for the object and then disposes of the object when the scope is complete. For example.

using (Font font2 = new Font("Arial", 10.0f))
{
    // use font2
}

See here for the MSDN article on the C# using keyword.

This might be what you are looking for:

<?php

$text = 'This is a Simple text.';

// this echoes "is is a Simple text." because 'i' is matched first
echo strpbrk($text, 'mi');

// this echoes "Simple text." because chars are case sensitive
echo strpbrk($text, 'S');
?>

Is it?

Or maybe this:

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Or even this

<?php
$email  = '[email protected]';
$domain = strstr($email, '@');
echo $domain; // prints @example.com

$user = strstr($email, '@', true); // As of PHP 5.3.0
echo $user; // prints name
?>

You can read all about them in the documentation here:

http://php.net/manual/en/book.strings.php

java.lang.StringBuilder. Use int constructor to create an initial size.

You can also do this much easier with a plugin called jQuery-confirm. All you have to do is add the script tag and the style sheet they provide in your page

<link rel="stylesheet" 
href="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-
confirm/3.3.0/jquery-confirm.min.js"></script>

And then an example of calling the alert box is:

   <script>
        $.alert({
    title: 'Alert!',
    content: 'Simple alert!',
     });

Is this what you are looking for:

myListBox.DataSource = MyList;

Althugh you asked for Google Maps API, I suggest an open source, working, legal, free and crowdsourced API by Open street maps

https://nominatim.openstreetmap.org/search?q=Mumbai&format=json

Here is the API documentation for reference.

Edit: It looks like there are discrepancies occasionally, at least in terms of postal codes, when compared to the Google Maps API, and the latter seems to be more accurate. This was the case when validating addresses in Canada with the Canada Post search service, however, it might be true for other countries too.

From Ubuntu Terminal, below works for me.

./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/'

uni2ascii is very handy:

$ echo -ne '????' | uni2ascii -aJ
%E4%BD%A0%E5%A5%BD%E4%B8%96%E7%95%8C

var str = "123456789";
var chunks = [];
var chunkSize = 2;

while (str) {
    if (str.length < chunkSize) {
        chunks.push(str);
        break;
    }
    else {
        chunks.push(str.substr(0, chunkSize));
        str = str.substr(chunkSize);
    }
}

alert(chunks); // chunks == 12,34,56,78,9

Spring Security Documentation mentions the reason for blocking // in the request.

For example, it could contain path-traversal sequences (like /../) or multiple forward slashes (//) which could also cause pattern-matches to fail. Some containers normalize these out before performing the servlet mapping, but others don’t. To protect against issues like these, FilterChainProxy uses an HttpFirewall strategy to check and wrap the request. Un-normalized requests are automatically rejected by default, and path parameters and duplicate slashes are removed for matching purposes.

So there are two possible solutions -

1. remove double slash (preferred approach)
2. Allow // in Spring Security by customizing the StrictHttpFirewall using the below code.

Step 1 Create custom firewall that allows slash in URL.

@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
    StrictHttpFirewall firewall = new StrictHttpFirewall();
    firewall.setAllowUrlEncodedSlash(true);    
    return firewall;
}

Step 2 And then configure this bean in websecurity

@Override
public void configure(WebSecurity web) throws Exception {
    //@formatter:off
    super.configure(web);
    web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
....
}

Step 2 is an optional step, Spring Boot just needs a bean to be declared of type HttpFirewall and it will auto-configure it in filter chain.

Spring Security 5.4 Update

In Spring security 5.4 and above (Spring Boot >= 2.4.0), we can get rid of too many logs complaining about the request rejected by creating the below bean.

import org.springframework.security.web.firewall.RequestRejectedHandler;
import org.springframework.security.web.firewall.HttpStatusRequestRejectedHandler;

@Bean
RequestRejectedHandler requestRejectedHandler() {
   return new HttpStatusRequestRejectedHandler();
}

I was asking the same too. Another solution is you could overload your method:

void remove_id(EmployeeClass);
void remove_id(ProductClass);
void remove_id(DepartmentClass);

in the call the argument will fit accordingly the object you pass. but then you will have to repeat yourself

void remove_id(EmployeeClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(ProductClass _obj) {
    int saveId = _obj->id;
    ...
};

void remove_id(DepartmentClass _obj) {
    int saveId = _obj->id;
    ...
};

Normally svn add * works. But if you get message like svn: warning: W150002: due to mix off versioned and non-versioned files in working copy. Use this command:

svn add <path to directory> --force

or

svn add * --force

After doing that don't forget to change your href in, <a href="{the chosen redirected name}"> home</a>

Example:

.htaccess file

RewriteEngine On

RewriteRule ^about/$ /about.php

PHP file:

<a href="about/"> about</a>

I would counsel against using if ($hash{$key}) since it will not do what you expect if the key exists but its value is zero or empty.

Since upgrading my typings to react 0.14.43 (I'm not sure exactly when this was introduced), the React.FormEvent type is now generic and this removes the need for a cast.

import React = require('react');

interface ITestState {
    selectedValue: string;
}

export class Test extends React.Component<{}, ITestState> {

    constructor() {
        super();
        this.state = { selectedValue: "A" };
    }

    change(event: React.FormEvent<HTMLSelectElement>) {
        // No longer need to cast to any - hooray for react!
        var safeSearchTypeValue: string = event.currentTarget.value;

        console.log(safeSearchTypeValue); // in chrome => B

        this.setState({
            selectedValue: safeSearchTypeValue
        });
    }

    render() {
        return (
            <div>
                <label htmlFor="searchType">Safe</label>
                <select className="form-control" id="searchType" onChange={ e => this.change(e) } value={ this.state.selectedValue }>
                    <option value="A">A</option>
                    <option value="B">B</option>
                </select>
                <h1>{this.state.selectedValue}</h1>
            </div>
        );
    }
}

Based on answer by @Cici I give here a more generic solution:

=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))

In Italian version of Excel:

=SOMMA(INDIRETTO(CONCATENA(B1;C1)):INDIRETTO(CONCATENA(B2;C2)))

Where B1-C2 cells hold these values:

• A, 1
• A, 5

You can change these valuese to change the final range at wish.

Splitting the formula in parts:

• SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))
• CONCATENATE(B1,C1) - result is A1
• INDIRECT(CONCATENATE(B1,C1)) - result is reference to A1

Hence:

=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))

results in

=SUM(A1:A5)

I'll write down here a couple of SEO keywords for Italian users:

• come creare dinamicamente l'indirizzo di un intervallo in excel
• formula per definire un intervallo di celle in excel.

Con la formula indicata qui sopra basta scrivere nelle caselle da B1 a C2 gli estremi dell'intervallo per vedelo cambiare dentro la formula stessa.

You can actually do this within the query.

$results = Project::orderBy('name')->get();

This will return all results with the proper order.

EDIT: chardet seems to be unmantained but most of the answer applies. Check https://pypi.org/project/charset-normalizer/ for an alternative

Correctly detecting the encoding all times is impossible.

(From chardet FAQ:)

However, some encodings are optimized for specific languages, and languages are not random. Some character sequences pop up all the time, while other sequences make no sense. A person fluent in English who opens a newspaper and finds “txzqJv 2!dasd0a QqdKjvz” will instantly recognize that that isn't English (even though it is composed entirely of English letters). By studying lots of “typical” text, a computer algorithm can simulate this kind of fluency and make an educated guess about a text's language.

There is the chardet library that uses that study to try to detect encoding. chardet is a port of the auto-detection code in Mozilla.

You can also use UnicodeDammit. It will try the following methods:

• An encoding discovered in the document itself: for instance, in an XML declaration or (for HTML documents) an http-equiv META tag. If Beautiful Soup finds this kind of encoding within the document, it parses the document again from the beginning and gives the new encoding a try. The only exception is if you explicitly specified an encoding, and that encoding actually worked: then it will ignore any encoding it finds in the document.
• An encoding sniffed by looking at the first few bytes of the file. If an encoding is detected at this stage, it will be one of the UTF-* encodings, EBCDIC, or ASCII.
• An encoding sniffed by the chardet library, if you have it installed.
• UTF-8
• Windows-1252

You want .iloc with double brackets.

import pandas as pd
df = pd.DataFrame({"date": range(10, 64, 8), "not_date": "fools"})
df.index += 17
df.iloc[[0,-1]][['date']]

You give .iloc a list of indexes - specifically the first and last, [0, -1]. That returns a dataframe from which you ask for the 'date' column. ['date'] will give you a series (yuck), and [['date']] will give you a dataframe.

For people that don't like horrible looking code with php tags blasted everywhere...

<?php
if (have_posts()):
  while (have_posts()) : the_post();
    the_content();
  endwhile;
else:
  echo '<p>Sorry, no posts matched your criteria.</p>';
endif;
?>

select * from my_table where my_field Like '[a-z][a-z]%'

Try using border=0 in the img tag to make the ugly square go away.

<img src="someimage.png" border="0" alt="some alternate text" />

Yesterday's date can be calculated as,

var prev_date = new Date();
prev_date.setDate(prev_date.getDate() - 1);

Update: Angular v6+

For Apps converted from older versions (Angular v2 - v5): HttpModule is now deprecated and you need to replace it with HttpClientModule or else you will get the error too.

1. In your app.module.ts replace import { HttpModule } from '@angular/http'; with the new HttpClientModule import { HttpClientModule} from "@angular/common/http"; Note: Be sure to then update the modules imports[] array by removing the old HttpModule and replacing it with the new HttpClientModule.
2. In any of your services that used HttpModule replace import { Http } from '@angular/http'; with the new HttpClient import { HttpClient } from '@angular/common/http';

3. Update how you handle your Http response. For example - If you have code that looks like this

   http.get('people.json').subscribe((res:Response) => this.people = res.json());

The above code example will result in an error. We no longer need to parse the response, because it already comes back as JSON in the config object.

The subscription callback copies the data fields into the component's config object, which is data-bound in the component template for display.

For more information please see the - Angular HttpClientModule - Official Documentation

I ran some other question regarding ARIA. But it's content looks more promising for this question. would like to share them

What is ARIA?

If you put effort into making your website accessible to users with a variety of different browsing habits and physical disabilities, you'll likely recognize the role and aria-* attributes. WAI-ARIA (Accessible Rich Internet Applications) is a method of providing ways to define your dynamic web content and applications so that people with disabilities can identify and successfully interact with it. This is done through roles that define the structure of the document or application, or through aria-* attributes defining a widget-role, relationship, state, or property.

ARIA use is recommended in the specifications to make HTML5 applications more accessible. When using semantic HTML5 elements, you should set their corresponding role.

And see this you tube video for ARIA live.

The solution is:

 $('body').scroll(function(e){
    console.log(e);
});

You can change the mysql root password by logging in to the database directly (mysql -h your_host -u root) then run

SET PASSWORD FOR root@localhost = PASSWORD('yourpassword');

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.
