The Replace operator means Replace something with something else; do not be confused with removal functionality.

Also you should send the result processed by the operator to a variable or to another operator. Neither .Replace(), nor -replace modifies the original variable.

To remove all spaces, use 'Replace any space symbol with empty string'

$string = $string -replace '\s',''

To remove all spaces at the beginning and end of the line, and replace all double-and-more-spaces or tab symbols to spacebar symbol, use

$string = $string -replace '(^\s+|\s+$)','' -replace '\s+',' '

or the more native System.String method

$string = $string.Trim()

Regexp is preferred, because ' ' means only 'spacebar' symbol, and '\s' means 'spacebar, tab and other space symbols'. Note that $string.Replace() does 'Normal' replace, and $string -replace does RegEx replace, which is more heavy but more functional.

Note that RegEx have some special symbols like dot (.), braces ([]()), slashes (\), hats (^), mathematical signs (+-) or dollar signs ($) that need do be escaped. ( 'my.space.com' -replace '\.','-' => 'my-space-com'. A dollar sign with a number (ex $1) must be used on a right part with care

'2033' -replace '(\d+)',$( 'Data: $1')
Data: 2033

UPDATE: You can also use $str = $str.Trim(), along with TrimEnd() and TrimStart(). Read more at System.String MSDN page.

In addition to others' suggestions you can get CSRF token errors if your session storage is not working.

In a recent case a colleague of mine changed 'session_prefix' to a value that had a space in it.

session_prefix: 'My Website'

This broke session storage, which in turn meant my form could not obtain the CSRF token from the session.

Other answers here address the general question of what the proper Content-Type for an XML response is, and conclude (as with What's the difference between text/xml vs application/xml for webservice response) that both text/xml and application/xml are permissible. However, none address whether there are any rules specific to sitemaps.

Answer: there aren't. The sitemap spec is https://www.sitemaps.org, and using Google site: searches you can confirm that it does not contain the words or phrases mime, mimetype, content-type, application/xml, or text/xml anywhere. In other words, it is entirely silent on the topic of what Content-Type should be used for serving sitemaps.

In the absence of any commentary in the sitemap spec directly addressing this question, we can safely assume that the same rules apply as when choosing the Content-Type of any other XML document - i.e. that it may be either text/xml or application/xml.

try this query to have sepratley count of each SELECT statements :

select field1,count(field1) as field1Count,field2,count(field2) as field2Counts,field3, count(field3) as field3Counts
from table_name
group by field1,field2,field3
having count(*) > 1

is just going to look for a div with class="outer inner", is that correct?

No, '.outer .inner' will look for all elements with the .inner class that also have an element with the .outer class as an ancestor. '.outer.inner' (no space) would give the results you're thinking of.

'.outer > .inner' will look for immediate children of an element with the .outer class for elements with the .inner class.

Both '.outer .inner' and '.outer > .inner' should work for your example, although the selectors are fundamentally different and you should be wary of this.

COPY your table (Name, Latitude, Longitude) FROM 'C:\Temp\your file.csv' DELIMITERS ',' CSV HEADER;

Use c:\Temp\"Your File"\.

boolean a = (x < z) && (x == x);

This kind will short-circuit, meaning if (x < z) evaluates to false then the latter is not evaluated, a will be false, otherwise && will also evaluate (x == x).

& is a bitwise operator, but also a boolean AND operator which does not short-circuit.

You can test them by something as follows (see how many times the method is called in each case):

public static boolean getFalse() {
    System.out.println("Method");
    return false;
}

public static void main(String[] args) {
    if(getFalse() && getFalse()) { }        
    System.out.println("=============================");        
    if(getFalse() & getFalse()) { }
}

Here you go...

- (NSString *)removeEndSpaceFrom:(NSString *)strtoremove{
    NSUInteger location = 0;
    unichar charBuffer[[strtoremove length]];
    [strtoremove getCharacters:charBuffer];
    int i = 0;
    for(i = [strtoremove length]; i >0; i--) {
        NSCharacterSet* charSet = [NSCharacterSet whitespaceCharacterSet];
        if(![charSet characterIsMember:charBuffer[i - 1]]) {
            break;
        }
    }
    return [strtoremove substringWithRange:NSMakeRange(location, i  - location)];
}

So now just call it. Supposing you have a string that has spaces on the front and spaces on the end and you just want to remove the spaces on the end, you can call it like this:

NSString *oneTwoThree = @"  TestString   ";
NSString *resultString;
resultString = [self removeEndSpaceFrom:oneTwoThree];

resultString will then have no spaces at the end.

Oh you can Output a message when using QT += gui and CONFIG += console.

You need printf("foo bar") but cout << "foo bar" doesn't works

With Javascript you can get full size profile images like this

pass your accessToken to the getface() function from your FB.init call

function getface(accessToken){
  FB.api('/me/friends', function (response) {
    for (id in response.data) { 
        var homie=response.data[id].id         
        FB.api(homie+'/albums?access_token='+accessToken, function (aresponse) {
          for (album in aresponse.data) {
            if (aresponse.data[album].name == "Profile Pictures") {                      
              FB.api(aresponse.data[album].id + "/photos", function(aresponse) {
                console.log(aresponse.data[0].images[0].source); 
              });                  
            }
          }   
        });
    }
  });
}

And make sure to set the z-index property to get the layering you want.

You need to import ProductName-Swift.h. Note that it's the product name - the other answers make the mistake of using the class name.

This single file is an autogenerated header that defines Objective-C interfaces for all Swift classes in your project that are either annotated with @objc or inherit from NSObject.

Considerations:

• If your product name contains spaces, replace them with underscores (e.g. My Project becomes My_Project-Swift.h)

• If your target is a framework, you need to import <ProductName/ProductName-Swift.h>

• Make sure your Swift file is member of the target

Delete all records. Do not reset the primary index like "truncate".

/// <summary>
/// SET - DELETE all record by table - no truncate - return deleted records
/// </summary>
public static int setListDelAllMYTABLE()
{
    // INIT
    int retObj = 0;
    using (MYDBEntities ctx = new MYDBEntities())
    {
        // GET - all record
        var tempAllRecord = ctx.MYTABLE.ToList();
        // RESET
        ctx.MYTABLE.RemoveRange(tempAllRecord);
        // SET - final save
        retObj += ctx.SaveChanges();
    }
    // RET
    return retObj;
}

In jQuery:

$('some_element').keypress(function(e){
       if(e.keyCode == 20){
             //caps lock was pressed
       }
});

This jQuery plugin (code) implements the same idea as in Rajesh's answer a bit more succinctly.

How was the database exported?

• If it was exported using exp and a full schema was exported, then

  1. Create the user:

     create user <username> identified by <password> default tablespace <tablespacename> quota unlimited on <tablespacename>;
     

  2. Grant the rights:

     grant connect, create session, imp_full_database to <username>;
     

  3. Start the import with imp:

     imp <username>/<password>@<hostname> file=<filename>.dmp log=<filename>.log full=y;
     

• If it was exported using expdp, then start the import with impdp:

  impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;
  

Looking at the error log, it seems you have not specified the directory, so Oracle tries to find the dmp file in the default directory (i.e., E:\app\Vensi\admin\oratest\dpdump\).

Either move the export file to the above path or create a directory object to pointing to the path where the dmp file is present and pass the object name to the impdp command above.

For aspnetcore-3.1, you can also use Problem() like below;

https://docs.microsoft.com/en-us/aspnet/core/web-api/handle-errors?view=aspnetcore-3.1

 [Route("/error-local-development")]
public IActionResult ErrorLocalDevelopment(
    [FromServices] IWebHostEnvironment webHostEnvironment)
{
    if (webHostEnvironment.EnvironmentName != "Development")
    {
        throw new InvalidOperationException(
            "This shouldn't be invoked in non-development environments.");
    }

    var context = HttpContext.Features.Get<IExceptionHandlerFeature>();

    return Problem(
        detail: context.Error.StackTrace,
        title: context.Error.Message);
}

Actually, to properly support sorting, filtering, etc. a CollectionViewSource should be used as a link between the DataGrid and the list, like this:

<Window.Resources>
  <CollectionViewSource x:Key="ItemCollectionViewSource" CollectionViewType="ListCollectionView"/>
</Window.Resources>   

The DataGrid line looks like this:

<DataGrid
  DataContext="{StaticResource ItemCollectionViewSource}"
  ItemsSource="{Binding}"
  AutoGenerateColumns="False">  

In the code behind, you link CollectionViewSource with your link.

CollectionViewSource itemCollectionViewSource;
itemCollectionViewSource = (CollectionViewSource)(FindResource("ItemCollectionViewSource"));
itemCollectionViewSource.Source = itemList;

For detailed example see my article on CoedProject: http://www.codeproject.com/Articles/683429/Guide-to-WPF-DataGrid-formatting-using-bindings

Keytool comes with your Java library. So you have to execute the Keytool command from your /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/bin directory. Or you can add JAVA_HOME to your environmental variables (Windows) or ~/.bash_profile (Linux)

This is another way to specify the range of the bit-vector.

x +: N, The start position of the vector is given by x and you count up from x by N.

There is also

x -: N, in this case the start position is x and you count down from x by N.

N is a constant and x is an expression that can contain iterators.

It has a couple of benefits -

1. It makes the code more readable.

2. You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.

Try something like:

B = np.reshape(A,(-1,ncols))

You'll need to make sure that you can divide the number of elements in your array by ncols though. You can also play with the order in which the numbers are pulled into B using the order keyword.

If you're looking for an online calculator for converting DP, SP, inches, millimeters, points or pixels to and from one another at different screen densities, this is the most complete tool I know of.

To answer the final question (the others seem thoroughly answered above), "Should I bubble up the exact exception or mask it using Exception?"

I am assuming you mean something like this:

public void myMethod() throws Exception {
    // ... something that throws FileNotFoundException ...
}

No, always declare the most precise exception possible, or a list of such. The exceptions you declare your method as capable of throwing are a part of the contract between your method and the caller. Throwing "FileNotFoundException" means that it is possible the file name isn't valid and the file will not be found; the caller will need to handle that intelligently. Throwing Exception means "Hey, sh*t happens. Deal." Which is a very poor API.

In the comments on the first article there are some examples where "throws Exception" is a valid and reasonable declaration, but that's not the case for most "normal" code you will ever write.

Since Hadoop 3.0.0 - Alpha 1 there was a Change in the port configuration:

http://localhost:50070

was moved to

http://localhost:9870

see https://issues.apache.org/jira/browse/HDFS-9427

You can run your file in http-server.

1> Have Node.js installed in your system.

2> In CMD, run the command npm install http-server -g

3> Navigate to the specific path of your file folder in CMD and run the command http-server

4> Go to your browser and type localhost:8080. Your Application should run there.

SELECT DATENAME(DW,CONVERT(VARCHAR(20),GETDATE(),101))

Original answer Nov 20 '15:

No option for a specific tag as of Today. Docker compose just does its magic and assigns a tag like you are seeing. You can always have some script call docker tag <image> <tag> after you call docker-compose.

Now there's an option as described above or here

build: ./dir
image: webapp:tag

The tricky part is a regex that includes a dash as one of the valid characters in a character class. The dash has to come immediately after the start for a (normal) character class and immediately after the caret for a negated character class. If you need a close square bracket too, then you need the close square bracket followed by the dash. Mercifully, you only need dash, hence the notation chosen.

grep '^[-d]rwx.*[0-9]$' "$@"

See: Regular Expressions and grep for POSIX-standard details.

Specific type of array in typescript

export class RegisterFormComponent 
{
     genders = new Array<GenderType>();   // Use any array supports different kind objects

     loadGenders()
     {
        this.genders.push({name: "Male",isoCode: 1});
        this.genders.push({name: "FeMale",isoCode: 2});
     }
}

type GenderType = { name: string, isoCode: number };    // Specified format

I had the same problem with a Gradle project with a test SourceSet with two resource directories.

This snippet comes from a main-module.gradle and adds a resource dir to the test SourceSet:

sourceSets {
    test {
        resources {
            srcDir('../other-module/src/test/resources')
        }
    }
}

Doing this I had two resource directories related to the test SourceSet of the project main-module:

../other-module/src/test/resources src/test/resources (relative to the main-module folder, automatically added by the java plugin)

I find out that if I had two files with the same name in both the source directories, something in the process resources stage went wrong. As result, no compilation started and for this reason no .class were copied in the bin directory, where JUnit was looking for the classes. The ClassNotFoundException disappeared just renaming one of the two files.

I had the same problem and non of the given answers worked. But I found a git commit with a fix that did work for me:

sup {
  font-size: 0.8em;
  line-height: 0;
  position: relative;
  vertical-align: baseline;
  top: -0.5em;
}

Personally, I find the TryParse method easier to read, which one you'll actually want to use depends on your use-case: if errors can be handled locally you are expecting errors and a bool from TryParse is good, else you might want to just let the exceptions fly.

I would expect the TryParse to be faster too, since it avoids the overhead of exception handling. But use a benchmark tool, like Jon Skeet's MiniBench to compare the various possibilities.

bar is deprecated. Please check ogp.me for the current docs.

You can try this:

//Your class instance
Publication publication = new Publication();

//Get class with full path(with package name)
Class<?> c = Class.forName("com.example.publication.models.Publication");

//Get method
Method  method = c.getDeclaredMethod ("setTitle", String.class);

//set value
method.invoke (publication,  "Value to want to set here...");

Based on the comments left above I ran this under sqlplus instead of SQL Developer and the UPDATE statement ran perfectly, leaving me to believe this is an issue in SQL Developer particularly as there was no ORA error number being returned. Thank you for leading me in the right direction.

Prior to standardization there was ioctl(...FIONBIO...) and fcntl(...O_NDELAY...), but these behaved inconsistently between systems, and even within the same system. For example, it was common for FIONBIO to work on sockets and O_NDELAY to work on ttys, with a lot of inconsistency for things like pipes, fifos, and devices. And if you didn't know what kind of file descriptor you had, you'd have to set both to be sure. But in addition, a non-blocking read with no data available was also indicated inconsistently; depending on the OS and the type of file descriptor the read may return 0, or -1 with errno EAGAIN, or -1 with errno EWOULDBLOCK. Even today, setting FIONBIO or O_NDELAY on Solaris causes a read with no data to return 0 on a tty or pipe, or -1 with errno EAGAIN on a socket. However 0 is ambiguous since it is also returned for EOF.

POSIX addressed this with the introduction of O_NONBLOCK, which has standardized behavior across different systems and file descriptor types. Because existing systems usually want to avoid any changes to behavior which might break backward compatibility, POSIX defined a new flag rather than mandating specific behavior for one of the others. Some systems like Linux treat all 3 the same, and also define EAGAIN and EWOULDBLOCK to the same value, but systems wishing to maintain some other legacy behavior for backward compatibility can do so when the older mechanisms are used.

New programs should use fcntl(...O_NONBLOCK...), as standardized by POSIX.

surround.vim is going to be your easiest answer. If you are truly set against using it, here are some examples for what you can do. Not necessarily the most efficient, but that's why surround.vim was written.

• Quote a word, using single quotes
  ciw'Ctrl+r"'
  • ciw - Delete the word the cursor is on, and end up in insert mode.
  • ' - add the first quote.
  • Ctrl+r" - Insert the contents of the " register, aka the last yank/delete.
  • ' - add the closing quote.
    
    
• Unquote a word that's enclosed in single quotes
  di'hPl2x
  • di' - Delete the word enclosed by single quotes.
  • hP - Move the cursor left one place (on top of the opening quote) and put the just deleted text before the quote.
  • l - Move the cursor right one place (on top of the opening quote).
  • 2x - Delete the two quotes.
    
    
• Change single quotes to double quotes
  va':s/\%V'\%V/"/g
  • va' - Visually select the quoted word and the quotes.
  • :s/ - Start a replacement.
  • \%V'\%V - Only match single quotes that are within the visually selected region.
  • /"/g - Replace them all with double quotes.

I think this approach is the right one:

public List<Class> getClasses() throws ClassNotFoundException {
    List<Class> classes;
    try {
        classes = Stream.of("java.lang.Object", "java.lang.Integer", "java.lang.String").map(className -> {
            try {
                return Class.forName(className);
            } catch (ClassNotFoundException e) {
                throw new UndeclaredThrowableException(e);
            }
        }).collect(Collectors.toList());
    } catch (UndeclaredThrowableException e) {
        if (e.getCause() instanceof ClassNotFoundException) {
            throw (ClassNotFoundException) e.getCause();
        } else {
            // this should never happen
            throw new IllegalStateException(e.getMessage(), e);
        }
    }
    return classes;
}

Wrapping the checked exception inside the Callable in a UndeclaredThrowableException (that’s the use case for this exception) and unwrapping it outside.

Yes, I find it ugly, and I would advise against using lambdas in this case and just fall back to a good old loop, unless you are working with a parallel stream and paralellization brings an objective benefit that justifies the unreadability of the code.

As many others have pointed out, there are solutions to this situation, and I hope one of them will make it into a future version of Java.

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

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

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

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

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

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

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

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

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

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

How do I suppress the message?

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

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

Alternatively, suppress the message with suppressPackageStartupMessages:

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

Impact of R's Startup Procedures on Function Masking

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

For example, the documentation there says:

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

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

How do I list all the masked functions?

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

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

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

fns <- lapply(envs, ls)

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

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

Find cases where the object appears more than once.

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

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

How do I prevent name conflict bugs?

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

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

I just wanna add this, when you access the position of the array like

arg[n]

is the same as

*(arg + n) than means an offset of n starting from de arg address.

so arg[0] will be *arg

If it's only a placeholder you are trying to achieve: a crazy approach is to inject text as an svg-background. It allows for some flexbility, and from what I've read the browser support should be fairly decent (haven't tested it though):

• Chrome >= 27
• FireFox >= 30
• Internet Explorer >= 9
• Safari >= 5.1

html:

<iframe class="iframe-placeholder" src=""></iframe>

css:

.iframe-placeholder
{
   background: url('data:image/svg+xml;charset=utf-8,<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 100% 100%"><text fill="%23FF0000" x="50%" y="50%" font-family="\'Lucida Grande\', sans-serif" font-size="24" text-anchor="middle">PLACEHOLDER</text></svg>') 0px 0px no-repeat;
}

What can you change?

Inside the background-value:

• font size: look for font-size="" and change the value to anything you want

• font color: look for fill="". Don't forget to replace the # with %23 if you're using hexadecimal color notation. %23 stands for a # in URL encoding which is necessary for the svg-string to be able to be parsed in FireFox.

• font family: look for font-family="" remember to escape the single quotes if you have a font that consists of multiple words (like with \'Lucida Grande\')

• text: look for the element value of the text-element where you see the PLACEHOLDER string. You can replace the PLACEHOLDER string with anything that is url-compliant (special characters need to be converted to percent notation)

Example on fiddle

Pros:

• No extra HTML-elements
• No js
• Text can easily (...) be adjusted without the need of an external program
• It's SVG, so you can easily put any SVG you want in there.

Cons:

• Browser support
• It's complex
• It's hacky
• If the iframe-src doesn't have a background set, the placeholder will shine through (which is not inherent to this method, but just standard behaviour when you use a bg on the iframe)

I would only recommend this only if it's absolutely necessary to show text as a placeholder in an iframe which requires a little bit of flexbility (multiple languages, ...). Just take a moment and reflect on it: is all this really necessary? If I had a choice, I'd go for @Christina's method

Other answers work, but

To get the full/default price:

$product->get_price_html();

printStackTrace() prints to a console. In production settings, nobody is ever watching at that. Suraj is correct, should pass this information to a logger.

Also, you can overwrite some variables:

s = input('UPPER CASE')
lower = s.lower()

If you use like this:

s = "Kilometer"
print(s.lower())     - kilometer
print(s)             - Kilometer

It will work just when called.

You can use the following commands:

• To save your uncommitted changes

  git stash

• To list your saved stashes

  git stash list

• To apply/get back the uncommited changes where x is 0,1,2...

  git stash apply stash@{x}

Note:

• To apply a stash and remove it from the stash list

  git stash pop stash@{x}

• To apply a stash and keep it in the stash list

  git stash apply stash@{x}

Using command line, you can do this:

AT \\computername time "NET STOP servicename"
AT \\computername time "NET START servicename"

npm set registry http://85.10.209.91/

(this proxy fetches the original data from registry.npmjs.org and manipulates the tarball urls to fix the tarball file structure issue).

The other solutions seem to have outdated versions.

In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.

I was using the HTTP_ACCEPT_LANGUAGE header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.

Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).

From what i understand, you can just manage windows using microsoft. hold control and select multiple windows in the taskbar, then right click it and tile whatever way you want. what i've been looking for is a way to actually split a physical monitor into two. so you can run not just windowed prgrams (explorer, firefox, whatever) but full screen programs like games or movies or whatever else you want. this is super useful to fix bugs in full screen programs. im tired of these "windows mangagers" its easier just to click and drag it where you want. and im not OCD about it lining up just right. i just want to split a monitor into two. is that so hard to ask?

I followed these steps:

Pull the master:

git pull origin master

This will sync your local repo with the Github repo. Add your new file and then:

git add .

Commit the changes:

git commit -m "adding new file  Xyz"

Finally, push the origin master:

git push origin master

Refresh your Github repo, you will see the newly added files.

Try this:

$Object = 'FirstPart SecondPart' | ConvertFrom-String -PropertyNames Val1, Val2
$Object.Val1
$Object.Val2

As @kosev said in his answer you can use JobIntentService. But I use an alternative solution - I catch IllegalStateException and start the service as foreground. For example, this function starts my service:

@JvmStatic
protected fun startService(intentAction: String, serviceType: Class<*>, intentExtraSetup: (Intent) -> Unit) {
    val context = App.context
    val intent = Intent(context, serviceType)
    intent.action = intentAction
    intentExtraSetup(intent)
    intent.putExtra(NEED_FOREGROUND_KEY, false)

    try {
        context.startService(intent)
    }
    catch (ex: IllegalStateException) {
        intent.putExtra(NEED_FOREGROUND_KEY, true)
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            context.startForegroundService(intent)
        }
        else {
            context.startService(intent)
        }
    }
}

and when I process Intent I do such thing:

override fun onHandleIntent(intent: Intent?) {
    val needToMoveToForeground = intent?.getBooleanExtra(NEED_FOREGROUND_KEY, false) ?: false
    if(needToMoveToForeground) {
        val notification = notificationService.createSyncServiceNotification()
        startForeground(notification.second, notification.first)

        isInForeground = true
    }

    intent?.let {
        getTask(it)?.process()
    }
}

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

Try this when your application still demands $parse, $eval, $watch like behavior in Angular

https://github.com/vinayk406/angular-expression-parser

An example to help you get off the ground.

for f in *.jpg; do mv "$f" "$(echo "$f" | sed s/IMG/VACATION/)"; done

In this example, I am assuming that all your image files contain the string IMG and you want to replace IMG with VACATION.

The shell automatically evaluates *.jpg to all the matching files.

The second argument of mv (the new name of the file) is the output of the sed command that replaces IMG with VACATION.

If your filenames include whitespace pay careful attention to the "$f" notation. You need the double-quotes to preserve the whitespace.

Since Java 8 this kind of code compiles as expected and the type parameter gets inferred by the compiler.

public Person(String name) {
    this(name, Collections.emptyList()); // Inferred to List<String> in Java 8
}

public Person(String name, List<String> nicknames) {
    this.name = name;
    this.nicknames = nicknames;
}

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only direct assignments and arguments to methods where used for type parameter inference.

In this case the parameter type of the constructor will be the target type for Collections.emptyList(), and the return value type will get chosen to match the parameter type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Java is getting closer to proper Hindley–Milner type inference with every release!

_{Old answer before your edit: http://jsfiddle.net/thirtydot/DsqWr/}

Easiest way is probably to convert from a VARCHAR to a DATE; then format it back to a VARCHAR again in the format you want;

SELECT TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') FROM EmpTable;

An SQLfiddle to test with.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Never fails, once I post the question to SO, I get some enlightening "aha" moment and figure it out. The solution:

    .container {_x000D_
       border: 1px solid #DDDDDD;_x000D_
       width: 200px;_x000D_
       height: 200px;_x000D_
       position: relative;_x000D_
    }_x000D_
    .tag {_x000D_
       float: left;_x000D_
       position: absolute;_x000D_
       left: 0px;_x000D_
       top: 0px;_x000D_
       z-index: 1000;_x000D_
       background-color: #92AD40;_x000D_
       padding: 5px;_x000D_
       color: #FFFFFF;_x000D_
       font-weight: bold;_x000D_
    }

<div class="container">_x000D_
       <div class="tag">Featured</div>_x000D_
       <img src="http://www.placehold.it/200x200">_x000D_
</div>

The key is the container has to be positioned relative and the tag positioned absolute.

<select id="test" name="sel">
  <option disabled>1</option>
  <option disabled>2</option>
</select>   

or you can use jQuery

$("#test option:not(:selected)").prop("disabled", true);

Its actually enough to add -m to startup parameters on Sql Server Configuration Manager, restart service, go to ssms an add checkbox sysadmin on your account, then remove -m restart again and use as usual.

-m Starts an instance of SQL Server in single-user mode.

Take a substr of the CLOB and then convert it to a char:

UPDATE IMS_TEST 
  SET TEST_Category           = 'just testing' 
WHERE to_char(substr(TEST_SCRIPT, 1, 9))    = 'something'
  AND ID                      = '10000239';

In C# Predicates are simply delegates that return booleans. They're useful (in my experience) when you're searching through a collection of objects and want something specific.

I've recently run into them in using 3rd party web controls (like treeviews) so when I need to find a node within a tree, I use the .Find() method and pass a predicate that will return the specific node I'm looking for. In your example, if 'a' mod 2 is 0, the delegate will return true. Granted, when I'm looking for a node in a treeview, I compare it's name, text and value properties for a match. When the delegate finds a match, it returns the specific node I was looking for.

You can use DataSourceBuilder if you are using jdbc starter. Also, in order to override the default autoconfiguration bean you need to mark your bean as a @Primary

In my case I have properties starting with datasource.postgres prefix.

E.g

@ConfigurationProperties(prefix = "datasource.postgres")
@Bean
@Primary
public DataSource dataSource() {
    return DataSourceBuilder
        .create()
        .build();
}

If it is not feasible for you, then you can use

@Bean
@Primary
public DataSource dataSource() {
    return DataSourceBuilder
        .create()
        .username("")
        .password("")
        .url("")
        .driverClassName("")
        .build();
}

As mentioned by Adam you have to take your system limitations into consideration before you can decide on approach whether you have enough memory to read it all into memory replace parts of it and re-write it.

If you're dealing with a small file or have no memory issues this might help:

Option 1) Read entire file into memory, do a regex substitution on the entire or part of the line and replace it with that line plus the extra line. You will need to make sure that the 'middle line' is unique in the file or if you have timestamps on each line this should be pretty reliable.

# open file with r+b (allow write and binary mode)
f = open("file.log", 'r+b')   
# read entire content of file into memory
f_content = f.read()
# basically match middle line and replace it with itself and the extra line
f_content = re.sub(r'(middle line)', r'\1\nnew line', f_content)
# return pointer to top of file so we can re-write the content with replaced string
f.seek(0)
# clear file content 
f.truncate()
# re-write the content with the updated content
f.write(f_content)
# close file
f.close()

Option 2) Figure out middle line, and replace it with that line plus the extra line.

# open file with r+b (allow write and binary mode)
f = open("file.log" , 'r+b')   
# get array of lines
f_content = f.readlines()
# get middle line
middle_line = len(f_content)/2
# overwrite middle line
f_content[middle_line] += "\nnew line"
# return pointer to top of file so we can re-write the content with replaced string
f.seek(0)
# clear file content 
f.truncate()
# re-write the content with the updated content
f.write(''.join(f_content))
# close file
f.close()

You should write your own stream manipulator

• http://www.two-sdg.demon.co.uk/curbralan/papers/WritingStreamManipulators.html

cout << multi(5) << "whatever" << "lolcat";

Requests and httplib2 are great options:

# Using requests.
import requests
request = requests.get(value)
if request.status_code == 200:
    return True
return False

# Using httplib2.
import httplib2

try:
    http = httplib2.Http()
    response = http.request(value, 'HEAD')

    if int(response[0]['status']) == 200:
        return True
except:
    pass
return False

If using Ansible, you can use the fetch_url function:

from ansible.module_utils.basic import AnsibleModule
from ansible.module_utils.urls import fetch_url

module = AnsibleModule(
    dict(),
    supports_check_mode=True)

try:
    response, info = fetch_url(module, url)
    if info['status'] == 200:
        return True

except Exception:
    pass

return False

I added the .ico file to my project, setting the Build Action to Embedded Resource. I specified the path to that file as the project's icon in the project settings, and then I used the code below in the form's constructor to share it. This way, I don't need to maintain a resources file anywhere with copies of the icon. All I need to do to update it is to replace the file.

var exe = System.Reflection.Assembly.GetExecutingAssembly();
var iconStream = exe.GetManifestResourceStream("Namespace.IconName.ico");
if (iconStream != null) Icon = new Icon(iconStream);

"Z" doesn't stand for "Zulu"

I don't have any more information than the Wikipedia article cited by the two existing answers, but I believe the interpretation that "Z" stands for "Zulu" is incorrect. UTC time is referred to as "Zulu time" because of the use of Z to identify it, not the other way around. The "Z" seems to have been used to mark the time zone as the "zero zone", in which case "Z" unsurprisingly stands for "zero" (assuming the following information from Wikipedia is accurate):

Around 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A–M (except J) to the east and N–Y to the west (J may be assigned to local time in non-nautical applications — zones M and Y have the same clock time but differ by 24 hours: a full day). These can be vocalized using the NATO phonetic alphabet which pronounces the letter Z as Zulu, leading to the use of the term "Zulu Time" for Greenwich Mean Time, or UT1 from January 1, 1972 onward.

mysql_connect("localhost", "root", "") or die(mysql_error()) ;

That image is called 'favicon' and it's a small square shaped .ico file, which is the standard file type for favicons. You could use .png or .gif too, but you should follow the standard for better compatibility.

To set one for your website you should:

1. Make a square image of your logo (preferably 32x32 or 16x16 pixels, as far as I know there's no max size*), and transform it into an .ico file. You can do this on Gimp, Photoshop (with help of a plugin) or a website like Favicon.cc or RealFaviconGenerator.

2. Then, you have two ways of setting it up:

   A) Placing it on the root folder/directory of your website (next to index.html) with the name favicon.ico.

   or

   B) Link to it between the <head></head> tags of every .html file on your site, like this:

   <head>
     <link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
   </head>
   

If you want to see the favicon from any website, just write www.url.com/favicon.ico and you'll (probably) see it. Stackoverflow's favicon is 16x16 pixels and Wikipedia is 32x32.

*: There's even a browser problem with no filesize limit. You could easily crash a browser with an exceedingly large favicon, more info here

You have to enable Type Name Handling and pass that to the (de)serializer as a settings parameter.

Base object1 = new Base() { Name = "Object1" };
Derived object2 = new Derived() { Something = "Some other thing" };
List<Base> inheritanceList = new List<Base>() { object1, object2 };

JsonSerializerSettings settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
string Serialized = JsonConvert.SerializeObject(inheritanceList, settings);
List<Base> deserializedList = JsonConvert.DeserializeObject<List<Base>>(Serialized, settings);

This will result in correct deserialization of derived classes. A drawback to it is that it will name all the objects you are using, as such it will name the list you are putting the objects in.

$('td').click(function() {
    var myCol = $(this).index();
    var $tr = $(this).closest('tr');
    var myRow = $tr.index();
});

That's exactly why the "fuser -m /mount/point" exists.

BTW, I don't think "fuser" or "lsof" will indicate when a resource is held by kernel module, although I don't usually have that issue..

I ended up spending quite some time going through material in this great thread. I doubt everyone wants to spend so much time so I would highlight the summary of what I learned and the solution I implemented.

Quick Summary

1. Is 1e-8 approximately same as 1e-16? If you are looking at noisy sensor data then probably yes but if you are doing molecular simulation then may be not! Bottom line: You always need to think of tolerance value in context of specific function call and not just make it generic app-wide hard-coded constant.
2. For general library functions, it's still nice to have parameter with default tolerance. A typical choice is numeric_limits::epsilon() which is same as FLT_EPSILON in float.h. This is however problematic because epsilon for comparing values like 1.0 is not same as epsilon for values like 1E9. The FLT_EPSILON is defined for 1.0.
3. The obvious implementation to check if number is within tolerance is fabs(a-b) <= epsilon however this doesn't work because default epsilon is defined for 1.0. We need to scale epsilon up or down in terms of a and b.
4. There are two solution to this problem: either you set epsilon proportional to max(a,b) or you can get next representable numbers around a and then see if b falls into that range. The former is called "relative" method and later is called ULP method.
5. Both methods actually fails anyway when comparing with 0. In this case, application must supply correct tolerance.

Utility Functions Implementation (C++11)

    TReal max_a = a + (std::nextafter(a, std::numeric_limits<TReal>::max()) - a) * interval_size;

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:

Use jQuery's IsNumeric method.

http://api.jquery.com/jQuery.isNumeric/

if ($.isNumeric(id)) {
   //it's numeric
}

CORRECTION: that would not ensure an integer. This would:

if ( (id+"").match(/^\d+$/) ) {
   //it's all digits
}

That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works

Here my complete authentication solution for your reference.

First, add the following four references

If you are looking for interoperability between different systems and languages, I would definately go for REST. I've had a lot of problems trying to get SOAP working between .NET and Java, for example.

1. extern "C" doesn't change the presence or absence of the __cplusplus macro. It just changes the linkage and name-mangling of the wrapped declarations.

2. You can nest extern "C" blocks quite happily.

3. If you compile your .c files as C++ then anything not in an extern "C" block, and without an extern "C" prototype will be treated as a C++ function. If you compile them as C then of course everything will be a C function.

4. Yes

5. You can safely mix C and C++ in this way.

There are two common "security" implications to using GET. Since data appears in the URL string its possible someone looking over your shoulder at Address Bar/URL may be able to view something they should not be privy to such as a session cookie that could potentially be used to hijack your session. Keep in mind everyone has camera phones.

The other security implication of GET has to do with GET variables being logged to most web servers access log as part of the requesting URL. Depending on the situation, regulatory climate and general sensitivity of the data this can potentially raise concerns.

Some clients/firewalls/IDS systems may frown upon GET requests containing an excessive amount of data and may therefore provide unreliable results.

POST supports advanced functionality such as support for multi-part binary input used for file uploads to web servers.

POST requires a content-length header which may increase the complexity of an application specific client implementation as the size of data submitted must be known in advance preventing a client request from being formed in an exclusively single-pass incremental mode. Perhaps a minor issue for those choosing to abuse HTTP by using it as an RPC (Remote Procedure Call) transport.

Others have already done a good job in covering the semantic differences and the "when" part of this question.

You absolutely can, I use this approach a lot w/ both JavaScript and PHP.

Field definition:

<input type="hidden" name="foo" value="<?php echo $var;?>" />

Access w/ PHP:

$_GET['foo'] or $_POST['foo']

Also: Don't forget to sanitize your inputs if they are going into a database. Feel free to use my routine: https://github.com/niczak/PHP-Sanitize-Post/blob/master/sanitize.php

Cheers!

Eclipse:

Having code higlighting, compiling in the background, pointing out my errors as I go along.

Integration with javadoc, suggesting variable names with ctrl-Space.

When I compile, I get errors right there. I can double click on an error, and it displays the appropriate line.

Really well integrated with JUnit, ctrl-F11 runs the test, tells me the tests have failed. If there is an exception in the output window, I can double click on a line, and takes me to the line that failed. Not only that, but ctrl-F11 makes sure everything is compiled before it runs the tests (which means I never forget to do that).

Integration with ant. One command to build and deploy the application.

Integration with debuggers, including remote debugging of web servers.

FANTASTIC refactoring tools, searching for references to a section of code. Helps me know the impact of a change.

All in all, it makes me more productive.

If you deployed the package to the "Integration Services Catalog" on SSMS you can retrieve the package using Visual studio.

Do everything in the inline of UL tag

<ul class="dropdown-menu scrollable-menu" role="menu" style="height: auto;max-height: 200px; overflow-x: hidden;">
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
                <li><a href="#">Something else here</a></li>
                <li><a href="#">Action</a></li>
                ..
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
            </ul>

Looking at your requirement, there is alternate solution as well. It seems you know the dimensions in dp at compile time, so you can add a dimen entry in the resources. Then you can query the dimen entry and it will be automatically converted to pixels in this call:

final float inPixels= mActivity.getResources().getDimension(R.dimen.dimen_entry_in_dp);

And your dimens.xml will have:

<dimen name="dimen_entry_in_dp">72dp</dimen>

Extending this idea, you can simply store the value of 1dp or 1sp as a dimen entry and query the value and use it as a multiplier. Using this approach you will insulate the code from the math stuff and rely on the library to perform the calculations.

The following is from Adobe docs.

The media queries specification also provides the keyword only, which is intended to hide media queries from older browsers. Like not, the keyword must come at the beginning of the declaration. For example:

media="only screen and (min-width: 401px) and (max-width: 600px)"

Browsers that don't recognize media queries expect a comma-separated list of media types, and the specification says they should truncate each value immediately before the first nonalphanumeric character that isn't a hyphen. So, an old browser should interpret the preceding example as this:

media="only"

Because there is no such media type as only, the stylesheet is ignored. Similarly, an old browser should interpret

media="screen and (min-width: 401px) and (max-width: 600px)"

as

media="screen"

In other words, it should apply the style rules to all screen devices, even though it doesn't know what the media queries mean.

Unfortunately, IE 6–8 failed to implement the specification correctly.

Instead of applying the styles to all screen devices, it ignores the style sheet altogether.

In spite of this behavior, it's still recommended to prefix media queries with only if you want to hide the styles from other, less common browsers.

So, using

media="only screen and (min-width: 401px)"

and

media="screen and (min-width: 401px)"

will have the same effect in IE6-8: both will prevent those styles from being used. They will, however, still be downloaded.

Also, in browsers that support CSS3 media queries, both versions will load the styles if the viewport width is larger than 401px and the media type is screen.

I'm not entirely sure which browsers that don't support CSS3 media queries would need the only version

media="only screen and (min-width: 401px)" 

as opposed to

media="screen and (min-width: 401px)"

to make sure it is not interpreted as

media="screen"

It would be a good test for someone with access to a device lab.

After compiling it you can jar it.

java -jar AppName.jar

<div class="container">
    <div class="row">
        <div class="col-md-12">
            <div class="row">
                <div class="col-md-4">  
                    <a href="">About</a>
                </div>
                <div class="col-md-4">
                    <img src="image.png">
                </div>
                <div class="col-md-4"> 
                    <a href="#myModal1" data-toggle="modal">SHARE</a>
                </div>
            </div>
        </div>
    </div>
</div>

You need to nest the interior columns inside of a row rather than just another column. It offsets the padding caused by the column with negative margins.

A simpler way would be

<div class="container">
   <div class="row">
       <div class="col-md-4">  
          <a href="">About</a>
       </div>
       <div class="col-md-4">
          <img src="image.png">
       </div>
       <div class="col-md-4"> 
           <a href="#myModal1" data-toggle="modal">SHARE</a>
       </div>
    </div>
</div>

That means a topic is appropriate. A queue means a message goes to one and only one possible subscriber. A topic goes to each and every subscriber.

Use df.count() to get the number of rows.

I will second madExcept and similar tools, like Eurekalog, but I think you can come a good way with FastMM also. With full debugmode enabled, it should give you some clues of whats wrong.

Anyway, even though Delphi uses FastMM as default, it's worth getting the full FastMM for it's additional control over logging.

Instead of

return new ResponseEntity<JSONObject>(entities, HttpStatus.OK);

try

return new ResponseEntity<List<JSONObject>>(entities, HttpStatus.OK);

Open terminal. Type the following

echo>sure.sh
chmod 700 sure.sh

Paste this inside sure.sh

#!\bin\bash

echo -n 'Are you sure? [Y/n] '
read yn

if [ "$yn" = "n" ]; then
    exit 1
fi

exit 0

Close sure.sh and type this in terminal.

alias sure='~/sure&&'

Now, if you type sure before typing the command it will give you an are you sure prompt before continuing the command.

Hope this is helpful!

This is working in my project. I think, This will be helpful for you.

If Date is in past then invert will 1.
If Date is in future then invert will 0.

$defaultDate = date('Y-m-d');   
$datetime1   = new DateTime('2013-03-10');  
$datetime2   = new DateTime($defaultDate);  
$interval    = $datetime1->diff($datetime2);  
$days        = $interval->format('%a');
$invert      = $interval->invert;

String text = readFileAsString("textfile.txt").replace("\n","");

.replace returns a new string, strings in Java are Immutable.

You can define the variable inside the document ready function without var to make it a global variable. In javascript any variable declared without var automatically becomes a global variable

$(document).ready(function() {
    intro =  "something";
});

although you cant use the variable immediately, but it would be accessible to other functions

I offer one more solution in case it is worthful for someone else.

I have a history.js file where I have the following:

import createHistory from 'history/createBrowserHistory'
const history = createHistory()
history.pushLater = (...args) => setImmediate(() => history.push(...args))
export default history

Next, on my Root where I define my router I use the following:

import history from '../history'
import { Provider } from 'react-redux'
import { Router, Route, Switch } from 'react-router-dom'

export default class Root extends React.Component {
  render() {
    return (
     <Provider store={store}>
      <Router history={history}>
       <Switch>
        ...
       </Switch>
      </Router>
     </Provider>
    )
   }
  }

Finally, on my actions.js I import History and make use of pushLater

import history from './history'
export const login = createAction(
...
history.pushLater({ pathname: PATH_REDIRECT_LOGIN })
...)

This way, I can push to new actions after API calls.

Hope it helps!

A callback function is a function you specify to an existing function/method, to be invoked when an action is completed, requires additional processing, etc.

In Javascript, or more specifically jQuery, for example, you can specify a callback argument to be called when an animation has finished.

In PHP, the preg_replace_callback() function allows you to provide a function that will be called when the regular expression is matched, passing the string(s) matched as arguments.

find . -type d > list.txt

Will list all directories and subdirectories under the current path. If you want to list all of the directories under a path other than the current one, change the . to that other path.

If you want to exclude certain directories, you can filter them out with a negative condition:

find . -type d ! -name "~snapshot" > list.txt

System32 is where Windows historically placed all 32bit DLLs, and System was for the 16bit DLLs. When microsoft created the 64 bit OS, everyone I know of expected the files to reside under System64, but Microsoft decided it made more sense to put 64bit files under System32. The only reasoning I have been able to find, is that they wanted everything that was 32bit to work in a 64bit Windows w/o having to change anything in the programs -- just recompile, and it's done. The way they solved this, so that 32bit applications could still run, was to create a 32bit windows subsystem called Windows32 On Windows64. As such, the acronym SysWOW64 was created for the System directory of the 32bit subsystem. The Sys is short for System, and WOW64 is short for Windows32OnWindows64.
Since windows 16 is already segregated from Windows 32, there was no need for a Windows 16 On Windows 64 equivalence. Within the 32bit subsystem, when a program goes to use files from the system32 directory, they actually get the files from the SysWOW64 directory. But the process is flawed.

It's a horrible design. And in my experience, I had to do a lot more changes for writing 64bit applications, that simply changing the System32 directory to read System64 would have been a very small change, and one that pre-compiler directives are intended to handle.

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

My favorite way of doing this is using PsExec.exe from SysInternals, available at http://technet.microsoft.com/en-us/sysinternals/bb897553

.\psexec.exe -accepteula -h -u "$username" -p "$password" cmd.exe

The "-h" switch is the one doing the magic:

-h If the target system is Vista or higher, has the process run with the account's elevated token, if available.

Here is a simple one liner

var segment = (arr, n) => arr.reduce((r,e,i) => i%n ? (r[r.length-1].push(e), r)_x000D_
                                                    : (r.push([e]), r), []),_x000D_
        arr = Array.from({length: 31}).map((_,i) => i+1);_x000D_
console.log(segment(arr,7));

There is a function strtobool in Python's standard library: http://docs.python.org/2/distutils/apiref.html?highlight=distutils.util#distutils.util.strtobool

You can use it to check user's input and transform it to True or False value.

Add two bindings to your website, one for local access and another for LAN access like so:

Open IIS and select your local website (that you want to access from your local network) from the left panel:

Connections > server (user-pc) > sites > local site

Open Bindings on the right panel under Actions tab add these bindings:

1. Local:

   Type: http
   Ip Address: All Unassigned
   Port: 80
   Host name: samplesite.local
   

2. LAN:

   Type: http
   Ip Address: <Network address of the hosting machine ex. 192.168.0.10>
   Port: 80
   Host name: <Leave it blank>
   

Voila, you should be able to access the website from any machine on your local network by using the host's LAN IP address (192.168.0.10 in the above example) as the site url.

NOTE:

if you want to access the website from LAN using a host name (like samplesite.local) instead of an ip address, add the host name to the hosts file on the local network machine (The hosts file can be found in "C:\Windows\System32\drivers\etc\hosts" in windows, or "/etc/hosts" in ubuntu):

192.168.0.10 samplesite.local

The below css code always keep the button at the bottom of the page

position:absolute;
bottom:0;

Since you want to do it in relative positioning, you should go for margin-top:100%

position:relative;
margin-top:100%;

EDIT1: JSFiddle1

EDIT2: To place button at center of the screen,

position:relative;
left: 50%;
margin-top:50%;

Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:

// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.

You can also ignore a single line with a trailing comment like this:

ignoreThis(); // jshint ignore:line

If you just want to disable validation for a single field in client side then you can override the validation attributes as follows:

@Html.TextBoxFor(model => model.SomeValue, 
                new Dictionary<string, object> { { "data-val", false }})

Allain Lalonde's link made my day. Just adding some simple working html code here.
Works with any reasonable browser since ages plus IE9+ and Presto-Opera 12.

<!DOCTYPE html>
<title>(XHR) Show all response headers</title>

<h1>All Response Headers with XHR</h1>
<script>
 var X= new XMLHttpRequest();
 X.open("HEAD", location);
 X.send();
 X.onload= function() { 
   document.body.appendChild(document.createElement("pre")).textContent= X.getAllResponseHeaders();
 }
</script>

Note: You get headers of a second request, the result may differ from the initial request.

<!DOCTYPE html>
<title>fetch() all Response Headers</title>

<h1>All Response Headers with fetch()</h1>
<script>
 var x= "";
 if(window.fetch)
    fetch(location, {method:'HEAD'})
    .then(function(r) {
       r.headers.forEach(
          function(Value, Header) { x= x + Header + "\n" + Value + "\n\n"; }
       );
    })
    .then(function() {
       document.body.appendChild(document.createElement("pre")).textContent= x;
    });
 else
   document.write("This does not work in your browser - no support for fetch API");
</script>

After making sure your environment is not active, type:

$ conda env remove --name ENVIRONMENT

Just create .gitignore file in your project folder Then add the name of the folder in it for ex:

frontend/node_modules

You can do this by just changing the html. Here's an example:

<hmtl>
  <head>
    <title>Some title</title>
  </head>
  <body> 
  <map name="navigatemap">
    <area shape="rect"  
          coords="166,4,319,41" 
          href="WII.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverWII).png'" 
    />
    <area shape="rect"
          coords="330,4,483,41" 
          href="OT.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOT).png'" 
    />

    <area shape="rect" 
          coords="491,3,645,41" 
          href="OP.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOP).png'" 
   />
  </map> 

  <img src="Assets/NavigationBar(OnHome).png" 
     name="navbar" 
     usemap="#navigatemap" />
  </body>
</html>

You could embed the '' default in your regex by adding |$:

>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''

Also works with re.search pointed out by others:

>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''

For oracle you can

group by trunc(created);

as this truncates the created datetime to the previous midnight.

Another option is to

group by to_char(created, 'DD.MM.YYYY');

which achieves the same result, but may be slower as it requires a type conversion.

If you don't have DBA rights then you can use user_segments table:

select bytes/1024/1024 MB from user_segments where segment_name='Table_name'

To get fixed padding, I will set layout to java.awt.GridBagLayout with one cell. You can then set padding for each cell. Then you can insert inner JPanel to that cell and (if you need) delegate proper JPanel methods to the inner JPanel.

Fully fleshed out example with arrows for only the red edges:

import networkx as nx
import matplotlib.pyplot as plt

G = nx.DiGraph()
G.add_edges_from(
    [('A', 'B'), ('A', 'C'), ('D', 'B'), ('E', 'C'), ('E', 'F'),
     ('B', 'H'), ('B', 'G'), ('B', 'F'), ('C', 'G')])

val_map = {'A': 1.0,
           'D': 0.5714285714285714,
           'H': 0.0}

values = [val_map.get(node, 0.25) for node in G.nodes()]

# Specify the edges you want here
red_edges = [('A', 'C'), ('E', 'C')]
edge_colours = ['black' if not edge in red_edges else 'red'
                for edge in G.edges()]
black_edges = [edge for edge in G.edges() if edge not in red_edges]

# Need to create a layout when doing
# separate calls to draw nodes and edges
pos = nx.spring_layout(G)
nx.draw_networkx_nodes(G, pos, cmap=plt.get_cmap('jet'), 
                       node_color = values, node_size = 500)
nx.draw_networkx_labels(G, pos)
nx.draw_networkx_edges(G, pos, edgelist=red_edges, edge_color='r', arrows=True)
nx.draw_networkx_edges(G, pos, edgelist=black_edges, arrows=False)
plt.show()

For CodeIgniter 4, you can use the built-in API Response Trait

Here's sample code for reference:

<?php namespace App\Controllers;

use CodeIgniter\API\ResponseTrait;

class Home extends BaseController
{
    use ResponseTrait;

    public function index()
    {
        $data = [
            'data' => 'value1',
            'data2' => 'value2',
        ];

        return $this->respond($data);
    }
}

Do,

git add .

while in the root of the repository. It will add everything. If you do git add *, it will only add the files * points to. The single dot refers to the directory.

If your directory or file wasn't added to git index/repo after the above command, remember to check if it's marked as ignored by git in .gitignore file.

At the present time, Intel graphics chips do not support CUDA. It is possible that, in the nearest future, these chips will support OpenCL (which is a standard that is very similar to CUDA), but this is not guaranteed and their current drivers do not support OpenCL either. (There is an Intel OpenCL SDK available, but, at the present time, it does not give you access to the GPU.)

Newest Intel processors (Sandy Bridge) have a GPU integrated into the CPU core. Your processor may be a previous-generation version, in which case "Intel(HD) graphics" is an independent chip.

pip install PyYAML

If libyaml is not found or compiled PyYAML can do without it on Mavericks.

Use the -J compression option for xz. And remember to man tar :)

tar cfJ <archive.tar.xz> <files>

Edit 2015-08-10:

If you're passing the arguments to tar with dashes (ex: tar -cf as opposed to tar cf), then the -f option must come last, since it specifies the filename (thanks to @A-B-B for pointing that out!). In that case, the command looks like:

tar -cJf <archive.tar.xz> <files>

You can do this inside your $.post calls success callback like this

$.post('mail.php',{name:$('#name').val(),
                              email:$('#e-mail').val(),
                              phone:$('#phone').val(),
                              message:$('#message').val()},

            //return the data
            function(data){

              //hide the graphic
              $('.bar').css({display:'none'});
              $('.loader').append(data);

              //clear fields
              $('input[type="text"],textarea').val('');

            });

Something like this should do the trick:

$(document).ready(function() {
    $('#toptitle').text(function(i, oldText) {
        return oldText === 'Profil' ? 'New word' : oldText;
    });
});

This only replaces the content when it is Profil. See text in the jQuery API.

To decode HTML take a look below code

string s = "Svendborg Værft A/S";
string a = HttpUtility.HtmlDecode(s);
Response.Write(a);

Output is like

 Svendborg Værft A/S

1. define it like your_field DATETIME NULL DEFAULT NULL
2. dont insert a blank string, insert a NULL INSERT INTO x(your_field)VALUES(NULL)

We can use date -d option

1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12

date -d '20121212' +'%Y-%m-%d'

2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format

date -d '20121212 -7 days' +'%Y-%m-%d'

3) If we are getting date in some variable say dat

dat2=$(date -d "$dat -1 days" +'%Y%m%d')

I've been in the need for this feature many times, therefore I've extracted it into a mixin. It can be used like this:

import windowScrollPosition from 'path/to/mixin.js'

new Vue({
  mixins: [ windowScrollPosition('position') ]
})

This creates a reactive position property (can be named whatever we like) on the Vue instance. The property contains the window scroll position as an [x,y] array.

Feel free to play around with this CodeSandbox demo.

Here's the code of the mixin. It's thoroughly commentated, so it should not be too hard to get an idea how it works:

function windowScrollPosition(propertyName) {
  return {
    data() {
      return {
        // Initialize scroll position at [0, 0]
        [propertyName]: [0, 0]
      }
    },
    created() {
      // Only execute this code on the client side, server sticks to [0, 0]
      if (!this.$isServer) {
        this._scrollListener = () => {
          // window.pageX/YOffset is equivalent to window.scrollX/Y, but works in IE
          // We round values because high-DPI devies can provide some really nasty subpixel values
          this[propertyName] = [
            Math.round(window.pageXOffset),
            Math.round(window.pageYOffset)
          ]
        }

        // Call listener once to detect initial position
        this._scrollListener()

        // When scrolling, update the position
        window.addEventListener('scroll', this._scrollListener)
      }
    },
    beforeDestroy() {
      // Detach the listener when the component is gone
      window.removeEventListener('scroll', this._scrollListener)
    }
  }
}

1. Open Run in your system.

2. Type %windir%\System32\cliconfg.exe

3. Click on ok button then check that the "TCP/IP Network Protocol Default Value Setup" pop-up is open.

4. Highlight TCP/IP under the Enabled protocols window.

5. Click the Properties button.

6. Enter the new port number, then click OK.

XMLBeans works great if you have a schema for your XML. It creates Java objects for the schema and creates easy to use parse methods.

For me the issue was I did not have my webpack build mode set to production for the package I was referencing in. Explicitly setting it to "build": "webpack --mode production" fixed the issue.

I solved this by renaming the branch in the file .git/refs/remotes/origin/HEAD.

Try this for stored procedures:

SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'P'
AND name = 'myProc'

How about an approach that not only allows multiple domains, but allows dynamic domains.

The use case here is with a Sharepoint app part which loads our site inside of Sharepoint via an iframe. The problem is that sharepoint has dynamic subdomains such as https://yoursite.sharepoint.com. So for IE, we need to specify ALLOW-FROM https://.sharepoint.com

Tricky business, but we can get it done knowing two facts:

1. When an iframe loads, it only validates the X-Frame-Options on the first request. Once the iframe is loaded, you can navigate within the iframe and the header isn't checked on subsequent requests.

2. Also, when an iframe is loaded, the HTTP referer is the parent iframe url.

You can leverage these two facts server side. In ruby, I'm using the following code:

  uri = URI.parse(request.referer)
  if uri.host.match(/\.sharepoint\.com$/)
    url = "https://#{uri.host}"
    response.headers['X-Frame-Options'] = "ALLOW-FROM #{url}"
  end

Here we can dynamically allow domains based upon the parent domain. In this case, we ensure that the host ends in sharepoint.com keeping our site safe from clickjacking.

I'd love to hear feedback on this approach.

System.Text.Json

This can now be done using System.Text.Json which is built-in to .NET Core 3.0. It's now possible to deserialize JSON without using third-party libraries.

var json = @"{""key1"":""value1"",""key2"":""value2""}";
var values = JsonSerializer.Deserialize<Dictionary<string, string>>(json);

Also available in NuGet package System.Text.Json if using .NET Standard or .NET Framework.

More generally, git help will help with at least simple questions like this:

zhasper@berens:/media/Kindle/documents$ git help
usage: git [--version] [--exec-path[=GIT_EXEC_PATH]] [--html-path] [-p|--paginate|--no-pager] [--bare] [--git-dir=GIT_DIR] [--work-tree=GIT_WORK_TREE] [--help] COMMAND [ARGS]

The most commonly used git commands are:
   add        Add file contents to the index
   :
   rm         Remove files from the working tree and from the index

I added a "Height" to my ListBox and it added the scrollbar nicely.

For me the problem was that I was running the migrate command not from inside the container where php was running. The extension was properly set there but not at my host machine.

You need to create an alias for the mother.kind. You do this like so.

Criteria c = session.createCriteria(Cat.class);
c.createAlias("mother.kind", "motherKind");
c.addOrder(Order.asc("motherKind.value"));
return c.list();

You need to change the xml file file_paths.xml from

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <files-path name="my_images" path="images/"/>
</paths>

to

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <fexeternal-path name="my_images" path="Android/data/com.example.marek.myapplication/files/Pictures"/>
</paths>

To install a service, run the InstallAndStart command as follows:

  SystemControl.InstallAndStart(
                                 "apache",
                                 "Apache Web Server",
                                 @"""c:\apache\bin\httpd.exe"" -k runservice"
  );

Make sure the account that is running the program has permission to install services. You can always 'Run As Administrator' on the program.

I have also included several commands for non-api access which do not install or remove services, but you can list them and control several (start, stop, restart). You really only need to elevate permissions for installing or removing services.

There are a couple of commands for getting and setting environment variables as well, such as OPENSSL_CONF or TEMP. For the most part, the parameters and method names should be pretty self-explanatory.

JonH has covered very well the part on how to write the query. There is another significant issue that must be mentioned too, however, which is the performance characteristics of such a query. Let's repeat it here (adapted to Oracle):

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(EmployeeName) > 4;

This query is restricting the result of a function applied to a column value (the result of applying the LENGTH function to the EmployeeName column). In Oracle, and probably in all other RDBMSs, this means that a regular index on EmployeeName will be useless to answer this query; the database will do a full table scan, which can be really costly.

However, various databases offer a function indexes feature that is designed to speed up queries like this. For example, in Oracle, you can create an index like this:

CREATE INDEX EmployeeTable_EmployeeName_Length ON EmployeeTable(LENGTH(EmployeeName));

This might still not help in your case, however, because the index might not be very selective for your condition. By this I mean the following: you're asking for rows where the name's length is more than 4. Let's assume that 80% of the employee names in that table are longer than 4. Well, then the database is likely going to conclude (correctly) that it's not worth using the index, because it's probably going to have to read most of the blocks in the table anyway.

However, if you changed the query to say LENGTH(EmployeeName) <= 4, or LENGTH(EmployeeName) > 35, assuming that very few employees have names with fewer than 5 character or more than 35, then the index would get picked and improve performance.

Anyway, in short: beware of the performance characteristics of queries like the one you're trying to write.

It depends on whether you are using JPA or Hibernate.

From the JPA 2.0 spec, the defaults are:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

And in hibernate, all is Lazy

UPDATE:

The latest version of Hibernate aligns with the above JPA defaults.

100% working Concept to send email with attachment in php :

if (isset($_POST['submit'])) {
  extract($_POST);
  require_once('mail/class.phpmailer.php');

  $subject = "$name Applied For - $position";
  $email_message = "<div>Thanks for Applying ....</div> ";

  $mail = new PHPMailer;
  $mail->IsSMTP(); // telling the class to use SMTP
  $mail->Host = "mail.companyname.com"; // SMTP server
  $mail->SMTPDebug = 0;
  $mail->SMTPAuth = true;
  $mail->SMTPSecure = "ssl";
  $mail->Host = "smtp.gmail.com";
  $mail->Port = 465;
  $mail->IsHTML(true);
  $mail->Username = "[email protected]";  // GMAIL username
  $mail->Password = "mailPassword";          // GMAIL password

  $mail->SetFrom('[email protected]', 'new application submitted');
  $mail->AddReplyTo("[email protected]","First Last");
  $mail->Subject = "your subject";

  $mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

  $mail->MsgHTML($email_message);

  $address = '[email protected]';
  $mail->AddAddress($address, "companyname");

  $mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']);      // attachment

  if (!$mail->Send()) {
    /* Error */
    echo 'Message not Sent! Email at [email protected]';
  } else {
    /* Success */
    echo 'Sent Successfully! <b> Check your Mail</b>';
  }
}

I used this code for google smtp mail sending with Attachment....

If you want to send exactly post request with verify=False option, fastest way is to use this code:

import requests

requests.api.request('post', url, data={'bar':'baz'}, json=None, verify=False)

Turns out that EVERY part of an NSAttributedString must have a dictionary set with at least NSFontAttributeName and NSForegroundColorAttributeName set, if you wish boundingRectWithSize to actually work!

I don't see that documented anywhere.

Also, CasperJS provides a nice high-level interface for navigation in PhantomJS, including clicking on links and filling out forms.

(Thanks to commenter Mr. M!)

Each node is named uniquely and knows who it is connected to. The List of connections allows for a Node to be connected to an arbitrary number of other nodes.

public class Node {
    public String name;
    public List<Edge> connections;
}

Each connection is directed, has a start and an end, and is weighted.

public class Edge {
    public Node start;
    public Node end;
    public double weight;
}

A graph is just your collection of nodes. Instead of List<Node> consider Map<String, Node> for fast lookup by name.

public class Graph {
    List<Node> nodes;
}

How about

sub foo()
  dim r As Range, rows As Long, i As Long
  Set r = ActiveSheet.Range("A1:Z50")
  rows = r.rows.Count
  For i = rows To 1 Step (-1)
    If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
  Next
End Sub

Try this

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Range("A" & i & ":" & "Z" & i)
            Else
                Set DelRange = Union(DelRange, Range("A" & i & ":" & "Z" & i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

IF you want to delete the entire row then use this code

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50

            Else
                Set DelRange = Union(DelRange, Rows(i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp

You can use this to get the parent directory of the current location of your py file.

Go into the mysql data directory and run du -h --max-depth=1 | grep databasename

According to the examples base64 encoding is directly supported, although I've not tested it myself. Take your base64 string (derived from a file or loaded with any other method, POST/GET, websockets etc), turn it to a binary with atob, and then parse this to getDocument on the PDFJS API likePDFJS.getDocument({data: base64PdfData}); Codetoffel answer does work just fine for me though.

Best Solution is go to File -> Sync Project With Gradle Files

I hope this helped

If you would like to redirect requests for "domain1.com" to "domain2.com", you could create a server block that looks like this:

server {
    listen 80;
    server_name domain1.com;
    return 301 $scheme://domain2.com$request_uri;
}

For binding Dynamic Data in a DropDownList you can do the following:

Create ViewBag in Controller like below

ViewBag.ContribTypeOptions = yourFunctionValue();

now use this value in view like below:

@Html.DropDownListFor(m => m.ContribType, 
    new SelectList(@ViewBag.ContribTypeOptions, "ContribId", 
                   "Value", Model.ContribTypeOptions.First().ContribId), 
    "Select, please")

Either of the latter two, since val could potentially be of a type that defines __eq__() to return true when passed None.

You should save the chart as a variable. On global scope, if its pure javascript, or as a class property, if its Angular.

Then you'll be able to use this reference to call destroy().

Pure Javascript:

var chart;

function startChart() {
    // Code for chart initialization
    chart = new Chart(...); // Replace ... with your chart parameters
}

function destroyChart() {
    chart.destroy();
}

Angular:

export class MyComponent {
    chart;

    constructor() {
        // Your constructor code goes here
    }

    ngOnInit() {
        // Probably you'll start your chart here

        // Code for chart initialization
        this.chart = new Chart(...); // Replace ... with your chart parameters
    }

    destroyChart() {
        this.chart.destroy();
    }
}

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

Selectors can be combined:

.bar:nth-child(2)

means "thing that has class bar" that is also the 2nd child.

You can make a bookmark with this as the url:

javascript:
var cached_anchors = $$('a');
for (var i in cached_anchors) {
    var ca = cached_anchors[i];
    if(ca.href.search('sprite') < 0 && ca.href.search('.png') > -1 || ca.href.search('.gif') > -1 || ca.href.search('.jpg') > -1) {
        var a = document.createElement('a');
        a.href = ca.innerHTML;
        a.target = '_blank';

        var img = document.createElement('img');
        img.src = ca.innerHTML;
        img.style.maxHeight = '100px';

        a.appendChild(img);
        document.getElementsByTagName('body')[0].appendChild(a);
    }
}
document.getElementsByTagName('body')[0].removeChild(document.getElementsByTagName('table')[0]);
void(0);

Then just go to chrome://cache and then click your bookmark and it'll show you all the images.

Use:

clear fileName:lineNum   // Removes all breakpoints at the specified line.
delete breakpoint number // Delete one breakpoint whose number is 'number'

On Debian 7 Wheezy, I had to do:

pip install --upgrade dnspython

even if python-dns package was installed.

When I started using json, I was confused and unable to figure it out for some time, but finally I got what I wanted
Here is the simple solution

import json
m = {'id': 2, 'name': 'hussain'}
n = json.dumps(m)
o = json.loads(n)
print(o['id'], o['name'])

i Did it, just follow this tutorial. helps a lot

The easiest way is to use a JsonResponse.

For a queryset, you should pass a list of the the values for that queryset, like so:

from django.http import JsonResponse

queryset = YourModel.objects.filter(some__filter="some value").values()
return JsonResponse({"models_to_return": list(queryset)})

If splitting very large files, the solution I found is an adaptation from this, with PowerShell "embedded" in a batch file. This works fast, as opposed to many other things I tried (I wouldn't know about other options posted here).

The way to use mysplit.bat below is

mysplit.bat <mysize> 'myfile'

Note: The script was intended to use the first argument as the split size. It is currently hardcoded at 100Mb. It should not be difficult to fix this.

Note 2: The filname should be enclosed in single quotes. Other alternatives for quoting apparently do not work.

Note 3: It splits the file at given number of bytes, not at given number of lines. For me this was good enough. Some lines of code could be probably added to complete each chunk read, up to the next CR/LF. This will split in full lines (not with a constant number of them), with no sacrifice in processing time.

set environment variable in deployment server(ex: like NODE_ENV=production). You can access your environmental variable through process.env.NODE_ENV. Find the following config file for the global settings

const env = process.env.NODE_ENV || "development"

const configs = {
    base: {
        env,
        host: '0.0.0.0',
        port: 3000,
        dbPort: 3306,
        secret: "secretKey for sessions",
        dialect: 'mysql',
        issuer : 'Mysoft corp',
        subject : '[email protected]',
    },
    development: {
        port: 3000,
        dbUser: 'root',
        dbPassword: 'root',

    },
    smoke: {
        port: 3000,
        dbUser: 'root',
    },
    integration: {
        port: 3000,
        dbUser: 'root',
    },
    production: {
        port: 3000,
        dbUser: 'root',
    }
};

const config = Object.assign(configs.base, configs[env]);

module.exports= config;

base contains common config for all environments.

then import in other modules like

const config =  require('path/to/config.js')
console.log(config.port)

Happy Coding...

After trying virtually every answer in SO, I finally found this gem that quickly removed and deleted the large files in my repository and allowed me to sync again: http://www.zyxware.com/articles/4027/how-to-delete-files-permanently-from-your-local-and-remote-git-repositories

CD to your local working folder and run the following command:

git filter-branch -f --index-filter "git rm -rf --cached --ignore-unmatch FOLDERNAME" -- --all

replace FOLDERNAME with the file or folder you wish to remove from the given git repository.

Once this is done run the following commands to clean up the local repository:

rm -rf .git/refs/original/
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now

Now push all the changes to the remote repository:

git push --all --force

This will clean up the remote repository.

A "u" prefix denotes the value has type unicode rather than str.

Raw string literals, with an "r" prefix, escape any escape sequences within them, so len(r"\n") is 2. Because they escape escape sequences, you cannot end a string literal with a single backslash: that's not a valid escape sequence (e.g. r"\").

"Raw" is not part of the type, it's merely one way to represent the value. For example, "\\n" and r"\n" are identical values, just like 32, 0x20, and 0b100000 are identical.

You can have unicode raw string literals:

>>> u = ur"\n"
>>> print type(u), len(u)
<type 'unicode'> 2

The source file encoding just determines how to interpret the source file, it doesn't affect expressions or types otherwise. However, it's recommended to avoid code where an encoding other than ASCII would change the meaning:

Files using ASCII (or UTF-8, for Python 3.0) should not have a coding cookie. Latin-1 (or UTF-8) should only be used when a comment or docstring needs to mention an author name that requires Latin-1; otherwise, using \x, \u or \U escapes is the preferred way to include non-ASCII data in string literals.

In addition to the existing answer it is possible to set a default option as follows:

echo off
ECHO A current build of Test Harness exists.
set delBuild=n
set /p delBuild=Delete preexisting build [y/n] (default - %delBuild%)?:

This allows users to simply hit "Enter" if they want to enter the default.

dynamic x = new ExpandoObject();
x.NewProp = string.Empty;

Alternatively:

var x = new ExpandoObject() as IDictionary<string, Object>;
x.Add("NewProp", string.Empty);

This is working fine:

$('#country').val($("#country option:contains('It\'s Me')").val());

double jhon = 3;
double[] numbers = new double[3];
for (int i = 0; i < 3; i++)

{
    numbers[i] = double.Parse(Console.ReadLine());

}
Console.WriteLine("\n");

Array.Sort(numbers);

for (int i = 0; i < 3; i++)
{
    Console.WriteLine(numbers[i]);

}

Console.ReadLine();

In your JSON format, it do not have starting JSON object

Like :

{
    "info" :       <!-- this is starting JSON object -->
        {
        "caller":"getPoiById",
        "results":
        {
            "indexForPhone":0,
            "indexForEmail":"NULL",
            .
            .
         }
    }
}

Above Json starts with info as JSON object. So while executing :

JSONObject json = new JSONObject(result);    // create JSON obj from string
JSONObject json2 = json.getJSONObject("info");    // this will return correct

Now, we can access result field :

JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"

I think this was missing and so the problem was solved while we use JSONTokener like answer of yours.

Your answer is very fine. Just i think i add this information so i answered

Thank you

Boost contains cstdint.hpp header file with the types you are looking for: http://www.boost.org/doc/libs/1_36_0/boost/cstdint.hpp

Just to add to the thread as a POSSIBLE solution, I faced a similar issue when developing on a Linux system that was behind a company firewall. However, using a Windows XP machine, Eclipse was able to access different update sites just fine as both the manual and native network connection providers worked just fine using the company proxy.

After stumbling around for some time, I came across a discussion about using NTLMv2 and an implementation to be found at http://cntlm.sourceforge.net/. To whomever posted this, I give much credit to as it helped me get past the issue running on Linux. As a side note, I was using Eclipse 3.6.2 / Helios on both the Linux and Windows distros.

Best of luck on finding a solution!

I have found that from version 1.8.4 on, the libraries can be found in ~/Arduino/Libraries. Hope this helps anyone else.

I suggest you to go to Query Browser and do the following:

1. Go to schemata and find the table you want to alter.

2. Right click and select copy create statement.

3. Open a result tab and paste the create statement their.

4. Go to the last line of the create statement and look for the Auto_Increment=N, (Where N is a current number for auto_increment field.)

5. Replace N with 1.

6. Press ctrl+enter.

Auto_increment should reset to one once you enter new row int the table.

I don't know what will happen if you try to add a row where an auto_increment field value already exist.

If compareParents(s1, s2) == -1 then compareParents(s2, s1) == 1 is expected. With your code it's not always true.

Specifically if s1.getParent() == s2 && s2.getParent() == s1. It's just one of the possible problems.

t.integer :retweets_count, :default => 0

... should work.

See the Rails guide on migrations

#!/bin/bash

pattern=$1
shift

for jar in $(find $* -type f -name "*.jar")
do
  match=`jar -tvf $jar | grep $pattern`
  if [ ! -z "$match" ]
  then
    echo "Found in: $jar"
    echo "$match"
  fi
done

This happens due to current branch has no tracking on the branch on the remote. so you can do it with 2 ways.

1. Pull with specific branch name

git pull origin master

2. Or you can specific branch to track to the local branch.

git branch --set-upstream-to=origin/

I achieved this with the code below.

First, you flex the container which makes the input and the icon be on the same line. Aligning items makes them be on the same level.

Then, make the input take up 100% of the width regardless. Give the icon absolute positioning which allows it to overlap with the input.

Then add right padding to the input so the text typed in doesn't get to the icon. And finally use the right css property to give the icon some space from the edge of the input.

Note: The Icon tag could be a real icon if you are working with ReactJs or a placeholder for any other way you work with icons in your project.

.inputContainer {
  display: flex;
  align-items: center;
  position: relative;
}

.input {
  width: 100%;
  padding-right: 40px;
}

.inputIcon {
  position: absolute;
  right: 10px;
}

<div class="inputContainer">
   <input class="input" />
   <Icon class="inputIcon" />
 </div>

Find below 3 methods:

readyState

Checking page readyState (not reliable):

def page_has_loaded(self):
    self.log.info("Checking if {} page is loaded.".format(self.driver.current_url))
    page_state = self.driver.execute_script('return document.readyState;')
    return page_state == 'complete'

The wait_for helper function is good, but unfortunately click_through_to_new_page is open to the race condition where we manage to execute the script in the old page, before the browser has started processing the click, and page_has_loaded just returns true straight away.

id

Comparing new page ids with the old one:

def page_has_loaded_id(self):
    self.log.info("Checking if {} page is loaded.".format(self.driver.current_url))
    try:
        new_page = browser.find_element_by_tag_name('html')
        return new_page.id != old_page.id
    except NoSuchElementException:
        return False

It's possible that comparing ids is not as effective as waiting for stale reference exceptions.

staleness_of

Using staleness_of method:

@contextlib.contextmanager
def wait_for_page_load(self, timeout=10):
    self.log.debug("Waiting for page to load at {}.".format(self.driver.current_url))
    old_page = self.find_element_by_tag_name('html')
    yield
    WebDriverWait(self, timeout).until(staleness_of(old_page))

If pattern match, copy next line into the pattern buffer, delete a return, then quit -- side effect is to print.

sed '/pattern/ { N; s/.*\n//; q }; d'
