use your ip address or a service like noip.com if you need something more practical. Then eventually configure your router properly so incoming connection will be forwarded to the machine with the server running.

As of npm 5, npm will now save by default. In case,if you would like npm to work in a similar old fashion (no autosave) to how it was working in previous versions, you can update the config option to enable autosave as below.

npm config set save false

To get the current setting, you can execute the following command:

npm config get save

With /^[a-zA-Z]/ you only check the first character:

• ^: Assert position at the beginning of the string
• [a-zA-Z]: Match a single character present in the list below:
  • a-z: A character in the range between "a" and "z"
  • A-Z: A character in the range between "A" and "Z"

If you want to check if all characters are letters, use this instead:

/^[a-zA-Z]+$/.test(str);

• ^: Assert position at the beginning of the string
• [a-zA-Z]: Match a single character present in the list below:
  • +: Between one and unlimited times, as many as possible, giving back as needed (greedy)
  • a-z: A character in the range between "a" and "z"
  • A-Z: A character in the range between "A" and "Z"
• $: Assert position at the end of the string (or before the line break at the end of the string, if any)

Or, using the case-insensitive flag i, you could simplify it to

/^[a-z]+$/i.test(str);

Or, since you only want to test, and not match, you could check for the opposite, and negate it:

!/[^a-z]/i.test(str);

We use this function to handle multiple subdomain and multiple tld also handle ip and localhost

function analyse_host($_host)
    {
        $my_host   = explode('.', $_host);
        $my_result = ['subdomain' => null, 'root' => null, 'tld' => null];

        // if host is ip, only set as root
        if(filter_var($_host, FILTER_VALIDATE_IP))
        {
            // something like 127.0.0.5
            $my_result['root'] = $_host;
        }
        elseif(count($my_host) === 1)
        {
            // something like localhost
            $my_result['root'] = $_host;
        }
        elseif(count($my_host) === 2)
        {
            // like jibres.com
            $my_result['root'] = $my_host[0];
            $my_result['tld']  = $my_host[1];
        }
        elseif(count($my_host) >= 3)
        {
            // some conditons like
            // ermile.ac.ir
            // ermile.jibres.com
            // ermile.jibres.ac.ir
            // a.ermile.jibres.ac.ir

            // get last one as tld
            $my_result['tld']  = end($my_host);
            array_pop($my_host);

            // check last one after remove is probably tld or not
            $known_tld    = ['com', 'org', 'net', 'gov', 'co', 'ac', 'id', 'sch', 'biz'];
            $probably_tld = end($my_host);
            if(in_array($probably_tld, $known_tld))
            {
                $my_result['tld'] = $probably_tld. '.'. $my_result['tld'];
                array_pop($my_host);
            }

            $my_result['root'] = end($my_host);
            array_pop($my_host);

            // all remain is subdomain
            if(count($my_host) > 0)
            {
                $my_result['subdomain'] = implode('.', $my_host);
            }
        }

        return $my_result;
    }

The verbose method to check if value is undefined or null is:

return value === undefined || value === null;

You can also use the == operator but this expects one to know all the rules:

return value == null; // also returns true if value is undefined

I actually had a situation where I needed to run multiple commands one after another from a package.json preinstall script in a way that would work on both Windows and Linux/OSX, so I couldn't rely on a non-core module.

So this is what I came up with:

#cmds.coffee
childproc = require 'child_process'

exports.exec = (cmds) ->
  next = ->
    if cmds.length > 0
      cmd = cmds.shift()
      console.log "Running command: #{cmd}"
      childproc.exec cmd, (err, stdout, stderr) ->
        if err? then console.log err
        if stdout? then console.log stdout
        if stderr? then console.log stderr
        next()
    else
      console.log "Done executing commands."

  console.log "Running the follows commands:"
  console.log cmds
  next()

You can use it like this:

require('./cmds').exec ['grunt coffee', 'nodeunit test/tls-config.js']

EDIT: as pointed out, this doesn't actually return the output or allow you to use the result of the commands in a Node program. One other idea for that is to use LiveScript backcalls. http://livescript.net/

I have a similar problem, I want to lock only 1 row. As far as I know, with UPDLOCK option, SQLSERVER locks all the rows that it needs to read in order to get the row. So, if you don't define a index to direct access to the row, all the preceded rows will be locked. In your example:

Asume that you have a table named TBL with an id field. You want to lock the row with id=10. You need to define a index for the field id (or any other fields that are involved in you select):

CREATE INDEX TBLINDEX ON TBL ( id )

And then, your query to lock ONLY the rows that you read is:

SELECT * FROM TBL WITH (UPDLOCK, INDEX(TBLINDEX)) WHERE id=10.

If you don't use the INDEX(TBLINDEX) option, SQLSERVER needs to read all rows from the beginning of the table to find your row with id=10, so those rows will be locked.

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

According to this article, you may try following command:

   ssh-add -l

If your key isn't in the list, then

   ssh-add /var/lib/jenkins/.ssh/id_rsa_project

Fast and simple Javascript image resizer:

https://github.com/calvintwr/blitz-hermite-resize

const blitz = Blitz.create()

/* Promise */
blitz({
    source: DOM Image/DOM Canvas/jQuery/DataURL/File,
    width: 400,
    height: 600
}).then(output => {
    // handle output
})catch(error => {
    // handle error
})

/* Await */
let resized = await blizt({...})

/* Old school callback */
const blitz = Blitz.create('callback')
blitz({...}, function(output) {
    // run your callback.
})

History

This is really after many rounds of research, reading and trying.

The resizer algorithm uses @ViliusL's Hermite script (Hermite resizer is really the fastest and gives reasonably good output). Extended with features you need.

Forks 1 worker to do the resizing so that it doesn't freeze your browser when resizing, unlike all other JS resizers out there.

I have faced same issue a couple of days ago while updating the database. In my case, there was few new non nullable columns added for maintenance which was not supplied in the code which is causing the exception. I figure out those fields and supplied values for them and its resolved.

You should use the same encoding on all layers of your application to avoid this problem. It is useful to add a filter to set the encoding:

public void doFilter(ServletRequest request,
                     ServletResponse response,
                     FilterChain chain) throws ServletException {
   request.setCharacterEncoding("UTF-8");
   chain.doFilter(request, response);
}

To only set the encoding on your JSP pages, add this line to them:

<%@ page contentType="text/html; charset=UTF-8" %>

Configure your database to use the same char encoding as well.

If you need to convert the encoding of a string see:

• Encoding conversion in java

I would not recommend to store HTML encoded text in your database. For example, if you need to generate a PDF (or anything other than HTML) you need to convert the HTML encoding first.

Had a friend show me this amazing site https://www.gitignore.io/. Enter the IDE of your choice or other options and it will automatically generate a gitignore file consisting of useful ignores, one of which is the xcuserstate. You can preview the gitignore file before downloading.

Follow the steps mentioned for using support ActionBar in Android Studio(0.4.2) :

Download the Android Support Repository from Android SDK Manager, SDK Manager icon will be available on Android Studio tool bar (or Tools -> Android -> SDK Manager).

After download you will find your Support repository here

$SDK_DIR\extras\android\m2repository\com\android\support\appcompat-v7

Open your main module's build.gradle file and add following dependency for using action bar in lower API level

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

Sync your project with gradle using the tiny Gradle icon available in toolbar (or Tools -> Android -> Sync Project With Gradle Files).

There is some issue going on with Android Studio 0.4.2 so check this as well if you face any issue while importing classes in code.

Import Google Play Services library in Android Studio

If Required follow the steps as well :

• Exit Android Studio
• Delete all the .iml files and files inside .idea folder from your project
• Relaunch Android Studio and wait till the project synced completely with gradle. If it shows an error in Event Log with import option click on Import Project.

This is bug in Android Studio 0.4.2 and fixed for Android Studio 0.4.3 release.

Use traceback.extract_stack() if you want convenient access to module and function names and line numbers.

Use ''.join(traceback.format_stack()) if you just want a string that looks like the traceback.print_stack() output.

Notice that even with ''.join() you will get a multi-line string, since the elements of format_stack() contain \n. See output below.

Remember to import traceback.

Here's the output from traceback.extract_stack(). Formatting added for readability.

>>> traceback.extract_stack()
[
   ('<string>', 1, '<module>', None),
   ('C:\\Python\\lib\\idlelib\\run.py', 126, 'main', 'ret = method(*args, **kwargs)'),
   ('C:\\Python\\lib\\idlelib\\run.py', 353, 'runcode', 'exec(code, self.locals)'),
   ('<pyshell#1>', 1, '<module>', None)
]

Here's the output from ''.join(traceback.format_stack()). Formatting added for readability.

>>> ''.join(traceback.format_stack())
'  File "<string>", line 1, in <module>\n
   File "C:\\Python\\lib\\idlelib\\run.py", line 126, in main\n
       ret = method(*args, **kwargs)\n
   File "C:\\Python\\lib\\idlelib\\run.py", line 353, in runcode\n
       exec(code, self.locals)\n  File "<pyshell#2>", line 1, in <module>\n'

I fixed the same problem on Google Chrome with the following:

1. Choose Customize and control Google Chrome (the button in the top right corner).

2. Choose Settings.

3. Go to Extensions.

4. Unmark all the extensions there. (They should show as Enable instead of Enabled.)

Recursive traverse object or array with array or objects elements:

function traverse(&$objOrArray)
{
    foreach ($objOrArray as $key => &$value)
    {
        if (is_array($value) || is_object($value))
        {
            traverse($value);
        }
        else
        {
            // DO SOMETHING
        }
    }
}

SVN is case-sensitive. Make sure that you're spelling it properly. If it got renamed, you can relocate the working folder to the new URL. See https://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-relocate.html

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

Let maven generate a batch file to start your application. This is the simplest way to this.

You can use the appassembler-maven-plugin for such purposes.

One is a static import (<%=@ include...>"), the other is a dynamic one (jsp:include). It will affect for example the path you gonna have to specify for your included file. A little research on Google will tell you more.

In case you are looking for a cut and paste method that creates and writes to a file, here's one I wrote that just takes a String input. Remove 'true' from PrintWriter if you want to overwrite the file each time.

private static final String newLine = System.getProperty("line.separator");

private synchronized void writeToFile(String msg)  {
    String fileName = "c:\\TEMP\\runOutput.txt";
    PrintWriter printWriter = null;
    File file = new File(fileName);
    try {
        if (!file.exists()) file.createNewFile();
        printWriter = new PrintWriter(new FileOutputStream(fileName, true));
        printWriter.write(newLine + msg);
    } catch (IOException ioex) {
        ioex.printStackTrace();
    } finally {
        if (printWriter != null) {
            printWriter.flush();
            printWriter.close();
        }
    }
}

In regards Jared's response, having Windows 2000 or better will not necessarily fix the issue at hand. Rob's response does work, however it is possible that this fix introduces security issues, as Windows updates will not be able to patch applications built as such.

In another post, Nick Guerrera suggests packaging the Visual C++ Runtime Redistributable with your applications, which installs quickly, and is independent of Visual Studio.

You can add an alias or a function in your startup script file. Usually this is .bashrc, .bash_login or .profile file in your home directory.

Since these files are hidden you will have to do an ls -a to list them. If you don't have one you can create one.

If I remember correctly, when I had bought my Mac, the .bash_login file wasn't there. I had to create it for myself so that I could put prompt info, alias, functions, etc. in it.

Here are the steps if you would like to create one:

1. Start up Terminal
2. Type cd ~/ to go to your home folder
3. Type touch .bash_profile to create your new file.
4. Edit .bash_profile with your favorite editor (or you can just type open -e .bash_profile to open it in TextEdit.
5. Type . .bash_profile to reload .bash_profile and update any alias you add.

<properties>
    <maven.test.skip>true</maven.test.skip>
</properties>

is also a way to add in pom file

Because "append" existed long before "pop" was thought of. Python 0.9.1 supported list.append in early 1991. By comparison, here's part of a discussion on comp.lang.python about adding pop in 1997. Guido wrote:

To implement a stack, one would need to add a list.pop() primitive (and no, I'm not against this particular one on the basis of any principle). list.push() could be added for symmetry with list.pop() but I'm not a big fan of multiple names for the same operation -- sooner or later you're going to read code that uses the other one, so you need to learn both, which is more cognitive load.

You can also see he discusses the idea of if push/pop/put/pull should be at element [0] or after element [-1] where he posts a reference to Icon's list:

I stil think that all this is best left out of the list object implementation -- if you need a stack, or a queue, with particular semantics, write a little class that uses a lists

In other words, for stacks implemented directly as Python lists, which already supports fast append(), and del list[-1], it makes sense that list.pop() work by default on the last element. Even if other languages do it differently.

Implicit here is that most people need to append to a list, but many fewer have occasion to treat lists as stacks, which is why list.append came in so much earlier.

myCars.Select((v, i) => new {car = v, index = i}).First(myCondition).index;

or the slightly shorter

myCars.Select((car, index) => new {car, index}).First(myCondition).index;

I tried the steps mentioned in the earlier posts but without any success. However, what worked for me was uninstalling R completely and then deleting the R folder which files in the documents folder, so basically everything do with R except the scripts and work spaces I had saved. I then reinstalled R and ran

remove.packages(c("ggplot2", "data.table"))
install.packages('Rcpp', dependencies = TRUE)
install.packages('ggplot2', dependencies = TRUE)
install.packages('data.table', dependencies = TRUE)

This rather crude method somehow worked for me.

JavaScript is always synchronous and single-threaded. If you're executing a JavaScript block of code on a page then no other JavaScript on that page will currently be executed.

JavaScript is only asynchronous in the sense that it can make, for example, Ajax calls. The Ajax call will stop executing and other code will be able to execute until the call returns (successfully or otherwise), at which point the callback will run synchronously. No other code will be running at this point. It won't interrupt any other code that's currently running.

JavaScript timers operate with this same kind of callback.

Describing JavaScript as asynchronous is perhaps misleading. It's more accurate to say that JavaScript is synchronous and single-threaded with various callback mechanisms.

jQuery has an option on Ajax calls to make them synchronously (with the async: false option). Beginners might be tempted to use this incorrectly because it allows a more traditional programming model that one might be more used to. The reason it's problematic is that this option will block all JavaScript on the page until it finishes, including all event handlers and timers.

Alternatively, if you do not wish to push to a repository:

1. Export the container to a tarball

   docker export <CONTAINER ID> > /home/export.tar
   

2. Move your tarball to new machine

3. Import it back

   cat /home/export.tar | docker import - some-name:latest
   

A quick fix where nothing else works:

const a.b = 5 // error

const a['b'] = 5 // error if ts-lint rule no-string-literal is enabled

const B = 'b'
const a[B] = 5 // always works

Not good practice but provides a solution without needing to turn off no-string-literal

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative
 #   expr       min         lq       mean     median         uq      max   neval
 # konvas()   1.00000   1.000000   1.000000   1.000000   1.000000  1.00000    20

For ncol = 10, the results are slighjtly different:

For me it worked to delete a Capability and then add it back.

Your compiled classes may need to be recompiled from the source with the new jars.

Try running "mvn clean" and then rebuild

Run

pip freeze

It works the same as above.

pip show pandas

I provide multiple solutions with descriptions in this answer. Feel free to ask questions if anything is unclear
PS: sadly someone merged this to the top answer without giving credit.

Quick and dirty solution:

Date.now() /1000 |0

Warning: it might break in 2038 and return negative numbers if you do the |0 magic. Use Math.floor() instead by that time

Math.floor() solution:

Math.floor(Date.now() /1000);

Some nerdy alternative by Derek ???? taken from the comments below this answer:

new Date/1e3|0

Polyfill to get Date.now() working:

To get it working in IE you could do this (Polyfill from MDN):

if (!Date.now) {
    Date.now = function now() {
        return new Date().getTime();
    };
}

If you do not care about the year / day of week / daylight saving time you could strip it away and use this after 2038:

var now = (function () {
    var year = new Date(new Date().getFullYear().toString()).getTime();
    return function () {
        return Date.now() - year
    }
})();

Some output of how it will look:

new Date()
Thu Oct 29 2015 08:46:30 GMT+0100 (Mitteleuropäische Zeit )
new Date(now())
Thu Oct 29 1970 09:46:30 GMT+0100 (Mitteleuropäische Zeit )

Of course it will break daylight saving time but depending on what you are building this might be useful to you if you need to do binary operations on timestamps after int32 will break in 2038.

This will also return negative values but only if the user of that PC you are running your code on is changing their PC's clock at least to 31th of december of the previous year.

If you just want to know the relative time from the point of when the code was run through first you could use something like this:

var relativeTime = (function () {
    var start = Date.now();
    return function () {
        return Date.now() - start
    }
})();

In case you are using jQuery you could use $.now() as described in jQuery's Docs which makes the polyfill obsolete since $.now() internally does the same thing: (new Date).getTime()

If you are just happy about jQuery's version consider upvoting this answer since I did not find it myself.

Now a tiny explaination of what |0 does:

By providing |, you tell the interpreter to do a binary OR operation. Bit operations require absolute numbers which turns the decimal result from Date.now() / 1000 into an integer.

During that conversion, decimals are removed, resulting in the same result as using Math.floor() but using less code.

Be warned though: it will convert a 64 bit double to a 32 bit integer. This will result in information loss when dealing with huge numbers. Timestamps will break after 2038 due to 32 bit integer overflow.

All answers on this page are really great for a complex object. But for those containing builtin iterable types as attributes, like str, list, set or dict, or any implementation of collections.Iterable, you can omit certain things in your class.

class Test(object):
    def __init__(self, string):
        self.string = string

    def __iter__(self):
        # since your string is already iterable
        return (ch for ch in self.string)
        # or simply
        return self.string.__iter__()
        # also
        return iter(self.string)

It can be used like:

for x in Test("abcde"):
    print(x)

# prints
# a
# b
# c
# d
# e

srand() seeds the random number generator. Without a seed, the generator is unable to generate the numbers you are looking for. As long as one's need for random numbers is not security-critical (e.g. any sort of cryptography), common practice is to use the system time as a seed by using the time() function from the <ctime> library as such: srand(time(0)). This will seed the random number generator with the system time expressed as a Unix timestamp (i.e. the number of seconds since the date 1/1/1970). You can then use rand() to generate a pseudo-random number.

Here is a quote from a duplicate question:

The reason is that a random number generated from the rand() function isn't actually random. It simply is a transformation. Wikipedia gives a better explanation of the meaning of pseudorandom number generator: deterministic random bit generator. Every time you call rand() it takes the seed and/or the last random number(s) generated (the C standard doesn't specify the algorithm used, though C++11 has facilities for specifying some popular algorithms), runs a mathematical operation on those numbers, and returns the result. So if the seed state is the same each time (as it is if you don't call srand with a truly random number), then you will always get the same 'random' numbers out.

If you want to know more, you can read the following:

Your question is dependent on the shell that you are using.

Bourne shell leaves very little in the way of what you're after.

BUT...

It does work, just about everywhere.

Just try and stay away from csh. It was good for the bells and whistles it added, compared the Bourne shell, but it is really creaking now. If you don't believe me, just try and separate out STDERR in csh! (-:

There are two possibilities here. The example above, namely using:

${MyVariable:=SomeDefault}

for the first time you need to refer to $MyVariable. This takes the env. var MyVariable and, if it is currently not set, assigns the value of SomeDefault to the variable for later use.

You also have the possibility of:

${MyVariable:-SomeDefault}

which just substitutes SomeDefault for the variable where you are using this construct. It doesn't assign the value SomeDefault to the variable, and the value of MyVariable will still be null after this statement is encountered.

There's always a problem accessing files on your file directory from a jar file. Providing the classpath in a jar file is very limited. Instead try using a bat file or a sh file to start your program. In that way you can specify your classpath anyway you like, referencing any folder anywhere on the system.

Also check my answer on this question:

Calling erase will invalidate iterators, you could use:

void erase(std::vector<int>& myNumbers_in, int number_in)
{
    std::vector<int>::iterator iter = myNumbers_in.begin();
    while (iter != myNumbers_in.end())
    {
        if (*iter == number_in)
        {
            iter = myNumbers_in.erase(iter);
        }
        else
        {
           ++iter;
        }
    }

}

Or you could use std::remove_if together with a functor and std::vector::erase:

struct Eraser
{
    Eraser(int number_in) : number_in(number_in) {}
    int number_in;
    bool operator()(int i) const
    {
        return i == number_in;
    }
};

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), Eraser(number_in)), myNumbers.end());

Instead of writing your own functor in this case you could use std::remove:

std::vector<int> myNumbers;
myNumbers.erase(std::remove(myNumbers.begin(), myNumbers.end(), number_in), myNumbers.end());

In C++11 you could use a lambda instead of a functor:

std::vector<int> myNumbers;
myNumbers.erase(std::remove_if(myNumbers.begin(), myNumbers.end(), [number_in](int number){ return number == number_in; }), myNumbers.end());

In C++17 std::experimental::erase and std::experimental::erase_if are also available, in C++20 these are (finally) renamed to std::erase and std::erase_if (note: in Visual Studio 2019 you'll need to change your C++ language version to the latest experimental version for support):

std::vector<int> myNumbers;
std::erase_if(myNumbers, Eraser(number_in)); // or use lambda

or:

std::vector<int> myNumbers;
std::erase(myNumbers, number_in);

This is a classic case of rebase --onto:

 # let's go to current master (X, where quickfix2 should begin)
 git checkout master

 # replay every commit *after* quickfix1 up to quickfix2 HEAD.
 git rebase --onto master quickfix1 quickfix2 

So you should go from

o-o-X (master HEAD)
     \ 
      q1a--q1b (quickfix1 HEAD)
              \
               q2a--q2b (quickfix2 HEAD)

to:

      q2a'--q2b' (new quickfix2 HEAD)
     /
o-o-X (master HEAD)
     \ 
      q1a--q1b (quickfix1 HEAD)

This is best done on a clean working tree.
See git config --global rebase.autostash true, especially after Git 2.10.

my.data.frame <- subset(data , V1 > 2 | V2 < 4)

An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:

new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]

Some people criticize the use of which as not needed, but it does prevent the NA values from throwing back unwanted results. The equivalent (.i.e not returning NA-rows for any NA's in V1 or V2) to the two options demonstrated above without the which would be:

 new.data <- data[ !is.na(data$V1 | data$V2) & ( data$V1 > 2 | data$V2 < 4)  , ]

Note: I want to thank the anonymous contributor that attempted to fix the error in the code immediately above, a fix that got rejected by the moderators. There was actually an additional error that I noticed when I was correcting the first one. The conditional clause that checks for NA values needs to be first if it is to be handled as I intended, since ...

> NA & 1
[1] NA
> 0 & NA
[1] FALSE

Order of arguments may matter when using '&".

Angular doesn't know about that change. For this you should call $scope.$digest() or make the change inside of $scope.$apply():

$scope.$apply(function() { 
   // every changes goes here
   $('#selectedDueDate').val(dateText); 
});

See this to better understand dirty-checking

If you move the files for whatever reason manually, then Elipse lost the reference and output a missing project file error, but the reason is thaty you move manually the files and Eclipse lost the reference

If you are using Spyder in the Anaconda package...

In the IPython Console, use

!conda install packageName

This works locally too.

!conda install /path/to/package.tar

Note: the ! is required when using IPython console from within Spyder.

The latest docker supports setting ulimits through the command line and the API. For instance, docker run takes --ulimit <type>=<soft>:<hard> and there can be as many of these as you like. So, for your nofile, an example would be --ulimit nofile=262144:262144

If you have installed via pip, just run the following

Use extension for UIImageView to Load URL Images.

The pid of a backgrounded child process is stored in $!. You can store all child processes' pids into an array, e.g. PIDS[].

wait [-n] [jobspec or pid …]

Wait until the child process specified by each process ID pid or job specification jobspec exits and return the exit status of the last command waited for. If a job spec is given, all processes in the job are waited for. If no arguments are given, all currently active child processes are waited for, and the return status is zero. If the -n option is supplied, wait waits for any job to terminate and returns its exit status. If neither jobspec nor pid specifies an active child process of the shell, the return status is 127.

Use wait command you can wait for all child processes finish, meanwhile you can get exit status of each child processes via $? and store status into STATUS[]. Then you can do something depending by status.

I have tried the following 2 solutions and they run well. solution01 is more concise, while solution02 is a little complicated.

solution01

#!/bin/bash

# start 3 child processes concurrently, and store each pid into array PIDS[].
process=(a.sh b.sh c.sh)
for app in ${process[@]}; do
  ./${app} &
  PIDS+=($!)
done

# wait for all processes to finish, and store each process's exit code into array STATUS[].
for pid in ${PIDS[@]}; do
  echo "pid=${pid}"
  wait ${pid}
  STATUS+=($?)
done

# after all processed finish, check their exit codes in STATUS[].
i=0
for st in ${STATUS[@]}; do
  if [[ ${st} -ne 0 ]]; then
    echo "$i failed"
  else
    echo "$i finish"
  fi
  ((i+=1))
done

solution02

#!/bin/bash

# start 3 child processes concurrently, and store each pid into array PIDS[].
i=0
process=(a.sh b.sh c.sh)
for app in ${process[@]}; do
  ./${app} &
  pid=$!
  PIDS[$i]=${pid}
  ((i+=1))
done

# wait for all processes to finish, and store each process's exit code into array STATUS[].
i=0
for pid in ${PIDS[@]}; do
  echo "pid=${pid}"
  wait ${pid}
  STATUS[$i]=$?
  ((i+=1))
done

# after all processed finish, check their exit codes in STATUS[].
i=0
for st in ${STATUS[@]}; do
  if [[ ${st} -ne 0 ]]; then
    echo "$i failed"
  else
    echo "$i finish"
  fi
  ((i+=1))
done

Renaming the file by moving it to a new name. (FileUtils is from Apache Commons IO lib)

  String newFilePath = oldFile.getAbsolutePath().replace(oldFile.getName(), "") + newName;
  File newFile = new File(newFilePath);

  try {
    FileUtils.moveFile(oldFile, newFile);
  } catch (IOException e) {
    e.printStackTrace();
  }

If you got only one column in the range to clean, just add "(1)" to the end. It indicates in wich column of the range Excel will remove the duplicates. Something like:

 Sub norepeat()

    Range("C8:C16").RemoveDuplicates (1)

End Sub

Regards

[[ -d "$DIR" && ! -L "$DIR" ]] && echo "It's a directory and not a symbolic link"

N.B: Quoting variables is a good practice.

Explanation:

• -d: check if it's a directory
• -L: check if it's a symbolic link

No there is no built-in support for this.

You have to make your own "INIFileReader". Maybe something like this?

var data = new Dictionary<string, string>();
foreach (var row in File.ReadAllLines(PATH_TO_FILE))
  data.Add(row.Split('=')[0], string.Join("=",row.Split('=').Skip(1).ToArray()));

Console.WriteLine(data["ServerName"]);

Edit: Updated to reflect Paul's comment.

Recently ran into a problem with this and a Chrome extension that was corrupting a JSON stream when the response header labeled the content-type as 'text/html' apparently extensions can and will use the response header to alter the content prior to further processing by the browser. Changing the content-type fixed the issue.

a = ['it']
b = ['was']
c = ['annoying']

a.extend(b)
a.extend(c)

# a now equals ['it', 'was', 'annoying']

You can write an extra function to process form data and you should add your nonform data as the data valu in the form.seethe example :

<form method="POST" id="add-form">
    <div class="form-group required ">
        <label for="key">Enter key</label>
        <input type="text" name="key" id="key"  data-nonformdata="hai"/>
    </div>
    <div class="form-group required ">
        <label for="name">Ente Name</label>
        <input type="text" name="name" id="name"  data-nonformdata="hello"/>
    </div>
    <input type="submit" id="add-formdata-btn" value="submit">
</form>

Then add this jquery for form processing

<script>
$(document).onready(function(){
    $('#add-form').submit(function(event){
        event.preventDefault();
        var formData = $("form").serializeArray();
        formData = processFormData(formData);
        // write further code here---->
    });
});
processFormData(formData)
{
    var data = formData;
    data.forEach(function(object){
        $('#add-form input').each(function(){
            if(this.name == object.name){
                var nonformData = $(this).data("nonformdata");
                formData.push({name:this.name,value:nonformData});
            }
        });
    });
    return formData;
}

On macOS, none of the answers worked for me. I discovered that was due to differences in how sed works on macOS and other BSD systems compared to GNU.

In particular BSD sed takes the -i option but requires a suffix for the backup (but an empty suffix is permitted)

grep version from this answer.

grep -rl 'foo' ./ | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

find version from this answer.

find . \( ! -regex '.*/\..*' \) -type f | LC_ALL=C xargs sed -i '' 's/foo/bar/g'

Don't omit the Regex to ignore . folders if you're in a Git repo. I realized that the hard way!

That LC_ALL=C option is to avoid getting sed: RE error: illegal byte sequence if sed finds a byte sequence that is not a valid UTF-8 character. That's another difference between BSD and GNU. Depending on the kind of files you are dealing with, you may not need it.

For some reason that is not clear to me, the grep version found more occurrences than the find one, which is why I recommend to use grep.

You should use this one too:

./gradlew :app:dependencies (Mac and Linux) -With ./

gradlew :app:dependencies (Windows) -Without ./

The libs you are using internally using any other versions of google play service.If yes then remove or update those libs.

I wrote some script for me its working .. I hope it may useful to you

</form>

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

Another way of doing this is to use ravel

model = forest.fit(train_fold, train_y.values.reshape(-1,))

You can use :

window.history.pushState('obj', 'newtitle', newUrlWithQueryString)

Simple answer: (watch for blank & null)

Edit:
In the newer version of pandas, you can pass the sheet name as a parameter.

file_name =  # path to file + file name
sheet =  # sheet name or sheet number or list of sheet numbers and names

import pandas as pd
df = pd.read_excel(io=file_name, sheet_name=sheet)
print(df.head(5))  # print first 5 rows of the dataframe

Check the docs for examples on how to pass sheet_name:
https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_excel.html

Old version:
you can use pandas package as well....

When you are working with an excel file with multiple sheets, you can use:

import pandas as pd
xl = pd.ExcelFile(path + filename)
xl.sheet_names

>>> [u'Sheet1', u'Sheet2', u'Sheet3']

df = xl.parse("Sheet1")
df.head()

df.head() will print first 5 rows of your Excel file

If you're working with an Excel file with a single sheet, you can simply use:

import pandas as pd
df = pd.read_excel(path + filename)
print df.head()

It's a place to put an embedded database, such as Sql Server Express, Access, or SQLite.

In my case the cause was AdBlock extension.

The request to server went through and I got the response but I could not see the request cookies due to "Provisional headers.." being shown in Dev tools. After disabling AdBlock for the site, the warning went away and dev tools started to show the cookies again.

For the change to take effect, it was also necessary to close the Dev tools and refresh the page

I recently had to resolve this issue and here's what I did :

First of all, this solution is around tuning Apache server.

Second main think is that there's a bug in the IE9 which means that the meta tag will not work, instead of this solution try this

• find/open your httpd.conf

• uncomment/or add the following line

  LoadModule headers_module modules/mod_headers.so
  

• add the following lines

  <IfModule headers_module>
      Header set X-UA-Compatible: IE=EmulateIE8
  </IfModule>
  

• save/restart your Apache server,

• browse to your page with IE9, use tools like wireshark or fiddler or use IE developer tools to check the header is there

Make sure if root project directory is coming up in sys.path output. If not, please add path of root project directory to sys.path.

Note that if you're using NSButton there is no setTitle func, instead, it's a property.

@IBOutlet weak var classToButton: NSButton!

The get(int index) method is declared to throw only the IndexOutOfBoundException which extends RuntimeException.
You are trying to tell Mockito to throw an exception SomeException() that is not valid to be thrown by that particular method call.

To clarify further.
The List interface does not provide for a checked Exception to be thrown from the get(int index) method and that is why Mockito is failing.
When you create the mocked List, Mockito will use the definition of List.class to creates its mock.

The behavior you are specifying with the when(list.get(0)).thenThrow(new SomeException()) doesn't match the method signature in List API, because get(int index) method does not throw SomeException() so Mockito fails.

If you really want to do this, then have Mockito throw a new RuntimeException() or even better throw a new ArrayIndexOutOfBoundsException() since the API specifies that that is the only valid Exception to be thrown.

It took me quite a while to figure out, how to not get a false when using openssl_decrypt() and get encrypt and decrypt working.

    // cryptographic key of a binary string 16 bytes long (because AES-128 has a key size of 16 bytes)
    $encryption_key = '58adf8c78efef9570c447295008e2e6e'; // example
    $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc'));
    $encrypted = openssl_encrypt($plaintext, 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, $iv);
    $encrypted = $encrypted . ':' . base64_encode($iv);

    // decrypt to get again $plaintext
    $parts = explode(':', $encrypted);
    $decrypted = openssl_decrypt($parts[0], 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, base64_decode($parts[1])); 

If you want to pass the encrypted string via a URL, you need to urlencode the string:

    $encrypted = urlencode($encrypted);

To better understand what is going on, read:

• http://blog.turret.io/the-missing-php-aes-encryption-example/
• http://thefsb.tumblr.com/post/110749271235/using-opensslendecrypt-in-php-

To generate 16 bytes long keys you can use:

    $bytes = openssl_random_pseudo_bytes(16);
    $hex = bin2hex($bytes);

To see error messages of openssl you can use: echo openssl_error_string();

Hope that helps.

As Daniel A. White said in his comment, the OPTIONS request is most likely created by the client as part of a cross domain JavaScript request. This is done automatically by Cross Origin Resource Sharing (CORS) compliant browsers. The request is a preliminary or pre-flight request, made before the actual AJAX request to determine which request verbs and headers are supported for CORS. The server can elect to support it for none, all or some of the HTTP verbs.

To complete the picture, the AJAX request has an additional "Origin" header, which identified where the original page which is hosting the JavaScript was served from. The server can elect to support request from any origin, or just for a set of known, trusted origins. Allowing any origin is a security risk since is can increase the risk of Cross site Request Forgery (CSRF).

So, you need to enable CORS.

Here is a link that explains how to do this in ASP.Net Web API

http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api#enable-cors

The implementation described there allows you to specify, amongst other things

• CORS support on a per-action, per-controller or global basis
• The supported origins
• When enabling CORS a a controller or global level, the supported HTTP verbs
• Whether the server supports sending credentials with cross-origin requests

In general, this works fine, but you need to make sure you are aware of the security risks, especially if you allow cross origin requests from any domain. Think very carefully before you allow this.

In terms of which browsers support CORS, Wikipedia says the following engines support it:

• Gecko 1.9.1 (FireFox 3.5)
• WebKit (Safari 4, Chrome 3)
• MSHTML/Trident 6 (IE10) with partial support in IE8 and 9
• Presto (Opera 12)

Java VM contains a single class object per class. Each class may have some shared variables called static variables. If the critical section of the code plays with these variables in a concurrent environment, then we need to make that particular section as synchronized. When there is more than one static synchronized method only one of them will be executed at a time without preemption. That's what lock on class object does.

Check this:

<?php
if (mysqli_num_rows(mysqli_query($con, sqlselectquery)) > 0)
{
    echo "found";
}
else
{
    echo "not found";
}
?>

What are the differences between the assignment operators = and <- in R?

As your example shows, = and <- have slightly different operator precedence (which determines the order of evaluation when they are mixed in the same expression). In fact, ?Syntax in R gives the following operator precedence table, from highest to lowest:

…
‘-> ->>’           rightwards assignment
‘<- <<-’           assignment (right to left)
‘=’                assignment (right to left)
…

But is this the only difference?

Since you were asking about the assignment operators: yes, that is the only difference. However, you would be forgiven for believing otherwise. Even the R documentation of ?assignOps claims that there are more differences:

The operator <- can be used anywhere, whereas the operator = is only allowed at the top level (e.g., in the complete expression typed at the command prompt) or as one of the subexpressions in a braced list of expressions.

Let’s not put too fine a point on it: the R documentation is wrong. This is easy to show: we just need to find a counter-example of the = operator that isn’t (a) at the top level, nor (b) a subexpression in a braced list of expressions (i.e. {…; …}). — Without further ado:

x
# Error: object 'x' not found
sum((x = 1), 2)
# [1] 3
x
# [1] 1

Clearly we’ve performed an assignment, using =, outside of contexts (a) and (b). So, why has the documentation of a core R language feature been wrong for decades?

It’s because in R’s syntax the symbol = has two distinct meanings that get routinely conflated (even by experts, including in the documentation cited above):

1. The first meaning is as an assignment operator. This is all we’ve talked about so far.
2. The second meaning isn’t an operator but rather a syntax token that signals named argument passing in a function call. Unlike the = operator it performs no action at runtime, it merely changes the way an expression is parsed.

So how does R decide whether a given usage of = refers to the operator or to named argument passing? Let’s see.

In any piece of code of the general form …

‹function_name›(‹argname› = ‹value›, …)
‹function_name›(‹args›, ‹argname› = ‹value›, …)

… the = is the token that defines named argument passing: it is not the assignment operator. Furthermore, = is entirely forbidden in some syntactic contexts:

if (‹var› = ‹value›) …
while (‹var› = ‹value›) …
for (‹var› = ‹value› in ‹value2›) …
for (‹var1› in ‹var2› = ‹value›) …

Any of these will raise an error “unexpected '=' in ‹bla›”.

In any other context, = refers to the assignment operator call. In particular, merely putting parentheses around the subexpression makes any of the above (a) valid, and (b) an assignment. For instance, the following performs assignment:

median((x = 1 : 10))

But also:

if (! (nf = length(from))) return()

_{Now you might object that such code is atrocious (and you may be right). But I took this code from the base::file.copy function (replacing <- with =) — it’s a pervasive pattern in much of the core R codebase.}

The original explanation by John Chambers, which the the R documentation is probably based on, actually explains this correctly:

[= assignment is] allowed in only two places in the grammar: at the top level (as a complete program or user-typed expression); and when isolated from surrounding logical structure, by braces or an extra pair of parentheses.

In sum, by default the operators <- and = do the same thing. But either of them can be overridden separately to change its behaviour. By contrast, <- and -> (left-to-right assignment), though syntactically distinct, always call the same function. Overriding one also overrides the other. Knowing this is rarely practical but it can be used for some fun shenanigans.

The other answers suggesting checking out the other branch, then committing to it, only work if the checkout is possible given the local modifications. If not, you're in the most common use case for git stash:

git stash
git checkout other-branch
git stash pop

The first stash hides away your changes (basically making a temporary commit), and the subsequent stash pop re-applies them. This lets Git use its merge capabilities.

If, when you try to pop the stash, you run into merge conflicts... the next steps depend on what those conflicts are. If all the stashed changes indeed belong on that other branch, you're simply going to have to sort through them - it's a consequence of having made your changes on the wrong branch.

On the other hand, if you've really messed up, and your work tree has a mix of changes for the two branches, and the conflicts are just in the ones you want to commit back on the original branch, you can save some work. As usual, there are a lot of ways to do this. Here's one, starting from after you pop and see the conflicts:

# Unstage everything (warning: this leaves files with conflicts in your tree)
git reset

# Add the things you *do* want to commit here
git add -p     # or maybe git add -i
git commit

# The stash still exists; pop only throws it away if it applied cleanly
git checkout original-branch
git stash pop

# Add the changes meant for this branch
git add -p
git commit

# And throw away the rest
git reset --hard

Alternatively, if you realize ahead of the time that this is going to happen, simply commit the things that belong on the current branch. You can always come back and amend that commit:

git add -p
git commit
git stash
git checkout other-branch
git stash pop

And of course, remember that this all took a bit of work, and avoid it next time, perhaps by putting your current branch name in your prompt by adding $(__git_ps1) to your PS1 environment variable in your bashrc file. (See for example the Git in Bash documentation.)

There is a bot that echoes your chat id upon starting a conversation.

Just search for @chatid_echo_bot and tap /start. It will echo your chat id.

Another option is @getidsbot which gives you much more information. This bot also gives information about a forwarded message (from user, to user, chad ids, etc) if you forward the message to the bot.

To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space

    <View
        android:layout_width="0dp"
        android:layout_height="20dp"
        android:layout_weight="1" />

Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.

    <ImageButton
        android:id="@+id/btnGenesis"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_marginBottom="2dp"
        android:layout_marginLeft="0dp"
        android:layout_marginTop="2dp"
        android:background="@null"
        android:gravity="left"
        android:src="@drawable/prev" />

    <View
        android:layout_width="0dp"

As has just happened to me - this can also happen when you add a required property to your model without updating your form. In this case the ValidationSummary will not list the error message.

In general error is which nobody can control or guess when it occurs.Exception can be guessed and can be handled. In Java Exception and Error are sub class of Throwable.It is differentiated based on the program control.Error such as OutOfMemory Error which no programmer can guess and can handle it.It depends on dynamically based on architectire,OS and server configuration.Where as Exception programmer can handle it and can avoid application's misbehavior.For example if your code is looking for a file which is not available then IOException is thrown.Such instances programmer can guess and can handle it.

And, of course

 ("ABCD"[2] == 2["ABCD"]) && (2["ABCD"] == 'C') && ("ABCD"[2] == 'C')

The main reason for this was that back in the 70's when C was designed, computers didn't have much memory (64KB was a lot), so the C compiler didn't do much syntax checking. Hence "X[Y]" was rather blindly translated into "*(X+Y)"

This also explains the "+=" and "++" syntaxes. Everything in the form "A = B + C" had the same compiled form. But, if B was the same object as A, then an assembly level optimization was available. But the compiler wasn't bright enough to recognize it, so the developer had to (A += C). Similarly, if C was 1, a different assembly level optimization was available, and again the developer had to make it explicit, because the compiler didn't recognize it. (More recently compilers do, so those syntaxes are largely unnecessary these days)

The Updated code is :

 private class SMSReceiver extends BroadcastReceiver {
                private Bundle bundle;
                private SmsMessage currentSMS;
                private String message;

                @Override
                public void onReceive(Context context, Intent intent) {

                    if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
                        bundle = intent.getExtras();
                        if (bundle != null) {
                            Object[] pdu_Objects = (Object[]) bundle.get("pdus");
                            if (pdu_Objects != null) {

                                for (Object aObject : pdu_Objects) {

                                    currentSMS = getIncomingMessage(aObject, bundle);

                                    String senderNo = currentSMS.getDisplayOriginatingAddress();

                                    message = currentSMS.getDisplayMessageBody();
                                    Toast.makeText(OtpActivity.this, "senderNum: " + senderNo + " :\n message: " + message, Toast.LENGTH_LONG).show();
                                }
                                this.abortBroadcast();
                                // End of loop
                            }
                        }
                    } // bundle null
                }
            }

        private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) {
            SmsMessage currentSMS;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                String format = bundle.getString("format");
                currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);
            } else {
                currentSMS = SmsMessage.createFromPdu((byte[]) aObject);
            }
    return currentSMS;
}

older code was :

Object [] pdus = (Object[]) myBundle.get("pdus");

    messages = new SmsMessage[pdus.length];

    for (int i = 0; i < messages.length; i++)
    {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            String format = myBundle.getString("format");
            messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i], format);
        }
        else {
            messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
        }
        strMessage += "SMS From: " + messages[i].getOriginatingAddress();
        strMessage += " : ";
        strMessage += messages[i].getMessageBody();
        strMessage += "\n";
    } 

The simple SYntax of code is :

private class SMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Telephony.Sms.Intents.SMS_RECEIVED_ACTION)) {
            SmsMessage[] smsMessages = Telephony.Sms.Intents.getMessagesFromIntent(intent);
            for (SmsMessage message : smsMessages) {
                // Do whatever you want to do with SMS.
            }
        }
    }
}

On the Mac, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

I launched the Console utility and scrolled down to ~/Library/Logs -> AndroidStudioBeta ->idea.log.1 (or any old log number)

Then I searched for “android.injected.signing.store” and found this from an earlier date:

-Pandroid.injected.signing.store.file=/Users/myuserid/AndroidStudioProjects/keystore/keystore.jks, 
-Pandroid.injected.signing.store.password=mystorepassword, 
-Pandroid.injected.signing.key.alias=myandroidkey, 
-Pandroid.injected.signing.key.password=mykeypassword,

On Windows

you can find your lost key password in below path

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin or ..taskHistory\taskHistory.bin

open the file using appropriate tools e.g. NotePad++ and search with the part of the password that you remember. You will find it definitely. Else, try searching with this string "signingConfig.storePassword".

Note: I have experienced the same and i am able to find it. In case if you didn't find may be you cleared all the cache and temp files.

var confirm=document.getElementById("confirm").value;
         if((confirm.checked==false)
         {
         alert("plz check the checkbox field");
         document.getElementbyId("confirm").focus();
         return false;
         }

Run:

rvm implode

Now you need to uninstall the RVM gem using:

gem uninstall rvm

Check if there are any remaining RVM files in your home directory, if yes remove them.

Go to the home directory and list all hidden files:

ls -a

rm  .rvm
rm  .rvmrc

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

Summary (Some examples of how to define methods in classes in python)

#!/usr/bin/env python   # (if running from bash)

class Class1(object):

    def A(self, arg1):
        print arg1
        # this method requires an instance of Class1   
        # can access self.variable_name, and other methods in Class1

    @classmethod
    def B(cls, arg1):
        cls.C(arg1)
        # can access methods B and C in Class1 

    @staticmethod
    def C(arg1):
        print arg1
        # can access methods B and C in Class1 
        # (i.e. via Class1.B(...) and Class1.C(...))

Example

my_obj=Class1()

my_obj.A("1")
# Class1.A("2") # TypeError: method A() must be called with Class1 instance

my_obj.B("3")
Class1.B("4")
my_obj.C("5")
Class1.C("6")`

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button2_Click(Sender, e)
End Sub

This Code call button click event programmatically

you can try this (I don't have sql server here today so I can't verify syntax, sorry)

select attributeName
  from tableName
 where CONVERT(varchar,attributeName,101) BETWEEN '03/01/2009' AND '03/31/2009'
   and CONVERT(varchar, attributeName,108) BETWEEN '06:00:00' AND '22:00:00'
   and DATEPART(day,attributeName) BETWEEN 2 AND 4

If you need to do it manually, one time:

First, merge in a temporary table, with something like:

create table MERGED as select * from table 1 UNION select * from table 2

Then, identify the primary key constraints with something like

SELECT COUNT(*), PK from MERGED GROUP BY PK HAVING COUNT(*) > 1

Where PK is the primary key field...

Solve the duplicates.

Rename the table.

[edited - removed brackets in the UNION query, which was causing the error in the comment below]

It seems you need to define your protocol as as subprotocol of NSObjectProtocol ... then you'll get respondsToSelector method

@objc protocol YourDelegate : NSObjectProtocol
{
    func yourDelegateMethod(passObject: SomeObject)
}

note that only specifying @objc was not enough. You should be also careful that the actual delegate is a subclass of NSObject - which in Swift might not be.

If you're going to be using arrays, consider the numpy or scipy packages, which give you arrays with a lot more flexibility.

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

You can use this:

Besides, you might want to use -iname instead of -name to catch files with ".PDF" (upper-case) extension as well.

The parentheses are poorly placed.

You need to use:

doThrow(new Exception()).when(mockedObject).methodReturningVoid(...);
                                          ^

This is explained in the documentation

You can remove "JavaAppletPlugin.plugin" found in Spotlight or Finder, then re-install downloaded Java 8.

This will simply solve your problem.

As said, the objectForKey: datatype is :(id)aKey whereas the valueForKey: datatype is :(NSString *)key.

For example:

 NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[NSArray arrayWithObject:@"123"],[NSNumber numberWithInteger:5], nil];

 NSLog(@"objectForKey : --- %@",[dict objectForKey:[NSNumber numberWithInteger:5]]);  
    //This will work fine and prints (    123    )  

 NSLog(@"valueForKey  : --- %@",[dict valueForKey:[NSNumber numberWithInteger:5]]); 
    //it gives warning "Incompatible pointer types sending 'NSNumber *' to parameter of type 'NSString *'"   ---- This will crash on runtime. 

So, valueForKey: will take only a string value and is a KVC method, whereas objectForKey: will take any type of object.

The value in objectForKey will be accessed by the same kind of object.

Very simple:

setlocal
cd /d %~dp0

Here is the corresponding presentViewController version that I used if it helps other newbies like myself:

if ([self respondsToSelector:@selector(presentModalViewController:animated:)]) {
    [self performSelector:@selector(presentModalViewController:animated:) withObject:testView afterDelay:0];
} else {
    [self presentViewController:configView animated:YES completion:nil];
}
[testView.testFrame setImage:info]; //this doesn't work for performSelector
[testView.testText setHidden:YES];

I had used a ViewController 'generically' and was able to get the modal View to appear differently depending what it was called to do (using setHidden and setImage). and things were working nicely before, but performSelector ignores 'set' stuff, so in the end it seems to be a poor solution if you try to be efficient like I tried to be...

why not try opening your file as text?

with open(fname, 'rt') as f:
    lines = [x.strip() for x in f.readlines()]

Additionally here is a link for python 3.x on the official page: https://docs.python.org/3/library/io.html And this is the open function: https://docs.python.org/3/library/functions.html#open

If you are really trying to handle it as a binary then consider encoding your string.

The manual uses the terms "callback" and "callable" interchangeably, however, "callback" traditionally refers to a string or array value that acts like a function pointer, referencing a function or class method for future invocation. This has allowed some elements of functional programming since PHP 4. The flavors are:

$cb1 = 'someGlobalFunction';
$cb2 = ['ClassName', 'someStaticMethod'];
$cb3 = [$object, 'somePublicMethod'];

// this syntax is callable since PHP 5.2.3 but a string containing it
// cannot be called directly
$cb2 = 'ClassName::someStaticMethod';
$cb2(); // fatal error

// legacy syntax for PHP 4
$cb3 = array(&$object, 'somePublicMethod');

This is a safe way to use callable values in general:

if (is_callable($cb2)) {
    // Autoloading will be invoked to load the class "ClassName" if it's not
    // yet defined, and PHP will check that the class has a method
    // "someStaticMethod". Note that is_callable() will NOT verify that the
    // method can safely be executed in static context.

    $returnValue = call_user_func($cb2, $arg1, $arg2);
}

Modern PHP versions allow the first three formats above to be invoked directly as $cb(). call_user_func and call_user_func_array support all the above.

See: http://php.net/manual/en/language.types.callable.php

Notes/Caveats:

1. If the function/class is namespaced, the string must contain the fully-qualified name. E.g. ['Vendor\Package\Foo', 'method']
2. call_user_func does not support passing non-objects by reference, so you can either use call_user_func_array or, in later PHP versions, save the callback to a var and use the direct syntax: $cb();
3. Objects with an __invoke() method (including anonymous functions) fall under the category "callable" and can be used the same way, but I personally don't associate these with the legacy "callback" term.
4. The legacy create_function() creates a global function and returns its name. It's a wrapper for eval() and anonymous functions should be used instead.

You must use OverridePendingTransition method to achieve it, which is in the Activity class. Sample Animations in the apidemos example's res/anim folder. Check it. More than check the demo in ApiDemos/App/Activity/animation.

Example:

@Override
public void onResume(){
    // TODO LC: preliminary support for views transitions
    this.overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}

Here's a simple working solution:

@-moz-keyframes spin { 100% { -moz-transform: rotate(360deg); } }
@-webkit-keyframes spin { 100% { -webkit-transform: rotate(360deg); } }
@keyframes spin { 100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); } }

.elem:hover {
    -webkit-animation:spin 1.5s linear infinite;
    -moz-animation:spin 1.5s linear infinite;
    animation:spin 1.5s linear infinite;
}

• Only one import needed.
• No if statement needed.
• Use the client built-in exception as intended.

Ex:

from boto3 import client

cli = client('iam')
try:
    cli.create_user(
        UserName = 'Brian'
    )
except cli.exceptions.EntityAlreadyExistsException:
    pass

a CloudWatch example:

cli = client('logs')
try:
    cli.create_log_group(
        logGroupName = 'MyLogGroup'
    )
except cli.exceptions.ResourceAlreadyExistsException:
    pass

I am facing the same issue, I am able to hide android keyboard even focus is in textbox by just adding one css property

<input type="text" style="pointer-events:none" />

and it works fine...

The message that you are getting is not for the default Exception of Python:

For a fresh python list, IndexError is thrown only on index not being in range (even docs say so).

>>> l = []
>>> l[1]
IndexError: list index out of range

If we try passing multiple items to list, or some other value, we get the TypeError:

>>> l[1, 2]
TypeError: list indices must be integers, not tuple

>>> l[float('NaN')]
TypeError: list indices must be integers, not float

However, here, you seem to be using matplotlib that internally uses numpy for handling arrays. On digging deeper through the codebase for numpy, we see:

static NPY_INLINE npy_intp
unpack_tuple(PyTupleObject *index, PyObject **result, npy_intp result_n)
{
    npy_intp n, i;
    n = PyTuple_GET_SIZE(index);
    if (n > result_n) {
        PyErr_SetString(PyExc_IndexError,
                        "too many indices for array");
        return -1;
    }
    for (i = 0; i < n; i++) {
        result[i] = PyTuple_GET_ITEM(index, i);
        Py_INCREF(result[i]);
    }
    return n;
}

where, the unpack method will throw an error if it the size of the index is greater than that of the results.

So, Unlike Python which raises a TypeError on incorrect Indexes, Numpy raises the IndexError because it supports multidimensional arrays.

In case you want the difference recursively, I have written a package for python: https://github.com/seperman/deepdiff

If they're both strings you can just do:

#define STR3 STR1 STR2

This then expands to:

#define STR3 "s" "1"

and in the C language, separating two strings with space as in "s" "1" is exactly equivalent to having a single string "s1".

Use these codes for 404 not found.

if(strstr($_SERVER['REQUEST_URI'],'index.php')){
  header('HTTP/1.0 404 Not Found');

}

Here 404missing.html is your Not found design page. (it can be .html or .php)

PowerShell has built-in XML and XPath functions. You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then .Node.'#text' to access node value.

[xml]$xml = Get-Content $serviceStatePath
$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml
$nodes | ForEach-Object {$_.Node.'#text'}

Or shorter

[xml]$xml = Get-Content $serviceStatePath
Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |
  % {$_.Node.'#text'}

The clean way to use mbstowcs is to call it twice to find the length of the result:

  const char * cs = <your input char*>
  size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);

  // error if wn == size_t(-1)

  wchar_t * buf = new wchar_t[wn + 1]();  // value-initialize to 0 (see below)

  wn = mbsrtowcs(buf, &cs, wn + 1, NULL);

  // error if wn == size_t(-1)

  assert(cs == NULL); // successful conversion

  // result now in buf, return e.g. as std::wstring

  delete[] buf;

Don't forget to call setlocale(LC_CTYPE, ""); at the beginning of your program!

The advantage over the Windows MultiByteToWideChar is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.

I usually wrap this method, along with the opposite one, in two conversion functions string->wstring and wstring->string. If you also add trivial overloads string->string and wstring->wstring, you can easily write code that compiles with the Winapi TCHAR typedef in any setting.

[Edit:] I added zero-initialization to buf, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn), though, but do beware if you plan on using C-style null-terminated arrays.[/]

In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.

Here is a small rant of mine on this topic.

List<Book> books_2 = new List<Book>(books_2.ToArray());

That should do exactly what you want. Demonstrated here.

The solution is much too big. Try this simple one. Please provide a 7+ character buffer, no check made.

char *i2str(int i, char *buf){
  byte l=0;
  if(i<0) buf[l++]='-';
  boolean leadingZ=true;
  for(int div=10000, mod=0; div>0; div/=10){
    mod=i%div;
    i/=div;
    if(!leadingZ || i!=0){
       leadingZ=false;
       buf[l++]=i+'0';
    }
    i=mod;
  }
  buf[l]=0;
  return buf;
}

Can be easily modified to give back end of buffer, if you discard index 'l' and increment the buffer directly.

I imagine a simple Replace in Files (Ctrl+Shift+H) will just about do the trick; simply replace namespace DemoApp with namespace MyApp. After that, build the solution and look for compile errors for unknown identifiers. Anything that fully qualified DemoApp will need to be changed to MyApp.

I experienced the same issue as the OP - Wordpress keeps redirecting to install-php after migration.

Problem was my database tables are named as prefix_tablename and I missed the underscore from $table_prefix in wp-config.

First, I'd like to apologize for bringing this question back up, but I felt that it could use another answer.

Derek Schultz is kind of correct. The '\b' character moves the printing cursor one character backwards, allowing you to overwrite the character that was printed there (it does not delete the entire line or even the character that was there unless you print new information on top). The following is an example of a progress bar using Java though it does not follow your format, it shows how to solve the core problem of overwriting characters (this has only been tested in Ubuntu 12.04 with Oracle's Java 7 on a 32-bit machine, but it should work on all Java systems):

public class BackSpaceCharacterTest
{
    // the exception comes from the use of accessing the main thread
    public static void main(String[] args) throws InterruptedException
    {
        /*
            Notice the user of print as opposed to println:
            the '\b' char cannot go over the new line char.
        */
        System.out.print("Start[          ]");
        System.out.flush(); // the flush method prints it to the screen

        // 11 '\b' chars: 1 for the ']', the rest are for the spaces
        System.out.print("\b\b\b\b\b\b\b\b\b\b\b");
        System.out.flush();
        Thread.sleep(500); // just to make it easy to see the changes

        for(int i = 0; i < 10; i++)
        {
            System.out.print("."); //overwrites a space
            System.out.flush();
            Thread.sleep(100);
        }

        System.out.print("] Done\n"); //overwrites the ']' + adds chars
        System.out.flush();
    }
}

I'm not sure how to extract the position from String.Index, but if you're willing to fall back on some Objective-C frameworks, you can bridge to objective-c and do it the same way you used to.

"abcdefghi".bridgeToObjectiveC().rangeOfString("c").location

It seems like some NSString methods haven't yet been (or maybe won't be) ported to String. Contains also comes to mind.

CREATE OR REPLACE can only be used on functions, procedures, types, views, or packages - it will not work on tables.

Code to simply get the contents as text instead of html:

'html_text' parameter is the string which you will pass in this function to get the text

from bs4 import BeautifulSoup

soup = BeautifulSoup(html_text, 'lxml')
text = soup.get_text()
print(text)

Your Code is:

FROM
 dbo.Employees
TO
 exe.Employees

I tried with this query.

ALTER SCHEMA exe TRANSFER dbo.Employees

Just write create schema exe and execute it

Go to the Sdk manager--> SDKtools --> instal the emulator 25.3.1

You are missing a semicolon at the end of your 'struct' definition.

Also,

Expanding on Mirek's answer, for the case when you want to use the swipe gestures inside a scroll view. By default the touch listener for the scroll view get disabled and therefore scroll action does not happen. In order to fix this you need to override the dispatchTouchEvent method of the Activity and return the inherited version of this method after you're done with your own listener.

In order to do a few modifications to Mirek's code: I add a getter for the gestureDetector in the OnSwipeTouchListener.

public GestureDetector getGestureDetector(){
    return  gestureDetector;
}

Declare the OnSwipeTouchListener inside the Activity as a class-wide field.

OnSwipeTouchListener onSwipeTouchListener;

Modify the usage code accordingly:

onSwipeTouchListener = new OnSwipeTouchListener(MyActivity.this) {
    public void onSwipeTop() {
        Toast.makeText(MyActivity.this, "top", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeRight() {
        Toast.makeText(MyActivity.this, "right", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeLeft() {
        Toast.makeText(MyActivity.this, "left", Toast.LENGTH_SHORT).show();
    }
    public void onSwipeBottom() {
        Toast.makeText(MyActivity.this, "bottom", Toast.LENGTH_SHORT).show();
    }
});

imageView.setOnTouchListener(onSwipeTouchListener);

And override the dispatchTouchEvent method inside Activity:

@Override
    public boolean dispatchTouchEvent(MotionEvent ev){
        swipeListener.getGestureDetector().onTouchEvent(ev); 
            return super.dispatchTouchEvent(ev);   
    }

Now both scroll and swipe actions should work.

No it is not possible in java (Maybe in java 8 it will be avilable). Except the case when you extend in a tree. For example:

class A
class B extends A
class C extends B

However this seems inefficient to me, as the filter will scan the whole list

No it won't - it will "break" as soon as the first element satisfying the predicate is found. You can read more about laziness in the stream package javadoc, in particular (emphasis mine):

Many stream operations, such as filtering, mapping, or duplicate removal, can be implemented lazily, exposing opportunities for optimization. For example, "find the first String with three consecutive vowels" need not examine all the input strings. Stream operations are divided into intermediate (Stream-producing) operations and terminal (value- or side-effect-producing) operations. Intermediate operations are always lazy.

Actually, when you do not want to use external sources (or cannot), I would recommend:

DEVICE=$(ls -l /sys/class/net | awk '$NF~/pci0/ { print $(NF-2); exit }')
IPADDR=$(ip -br address show dev $DEVICE | awk '{print substr($3,1,index($3,"/")-1);}')

The first line gets the name of the first network device on the PCI bus, the second one gives you its IP address.

BTW ps ... | grep ... | awk ... stinks. awk does not need grep.

I'll post what worked for me, thanks to @xavi-montero.

Put your CSS in your bundle's Resource/public/css directory, and your images in say Resource/public/img.

            apply_to: "\.css$"

Now install assets and compile with assetic:

$ rm -r app/cache/* # just in case
$ php app/console assets:install --symlink
$ php app/console assetic:dump --env=prod

This is good enough for the development box, and --symlink is useful, so you don't have to reinstall your assets (for example, you add a new image) when you enter through app_dev.php.

For the production server, I just removed the '--symlink' option (in my deployment script), and added this command at the end:

$ rm -r web/bundles/*/css web/bundles/*/js # all this is already compiled, we don't need the originals

All is done. With this, you can use paths like this in your .css files: ../img/picture.jpeg

If it's not the Home edition of XP, you can use \\servername\c$

Mark Brackett's comment:

Note that you need to be an Administrator on the local machine, as the share permissions are locked down

It 's working for me!

//
if(isset($_POST['post_var'])&&$_POST['post_var']!==''){
echo $_POST['post_var'];
}

//results:
1 if $_POST['post_var']='1'
0 if $_POST['post_var']='0'
skip if $_POST['post_var']=''

I also had the same problem and and it looks like this problem is due to the gradle version in the project directory

• This is the version of my jdk:

openjdk version "15-ea" 2020-09-15
OpenJDK Runtime Environment (build 15-ea+32-Ubuntu-220.04)
OpenJDK 64-Bit Server VM (build 15-ea+32-Ubuntu-220.04, mixed mode, sharing)

• Please check gradle whether it is installed. This is the version of my gradle:

------------------------------------------------------------
Gradle 6.8

• Then open the gradle-wrapper.properties file in your project folder, in the folder: project name/android/gradle/wrapper/gradle-wrapper.properties

• Change the gradle version. Here I changed the gradle version to 6.5

As of V8 v7.0 / Chrome 70, V8 uses TimSort, Python's sorting algorithm. Chrome 70 was released on September 13, 2018.

See the the post on the V8 dev blog for details about this change. You can also read the source code or patch 1186801.

For those using CanCanCan:

You will get this error if CanCanCan cannot find the correct params method.

For the :create action, CanCan will try to initialize a new instance with sanitized input by seeing if your controller will respond to the following methods (in order):

1. create_params
2. <model_name>_params such as article_params (this is the default convention in rails for naming your param method)
3. resource_params (a generically named method you could specify in each controller)

Additionally, load_and_authorize_resource can now take a param_method option to specify a custom method in the controller to run to sanitize input.

You can associate the param_method option with a symbol corresponding to the name of a method that will get called:

class ArticlesController < ApplicationController
  load_and_authorize_resource param_method: :my_sanitizer

  def create
    if @article.save
      # hurray
    else
      render :new
    end
  end

  private

  def my_sanitizer
    params.require(:article).permit(:name)
  end
end

Just use \" instead ", it should resolve the issue.

A variant of Marks (excellent) answer

• Add "using"s
• Make the class IDisposable
• Remove the URL encoding code to make the example simpler.
• Add a simple test fixture to demonstrate usage

Hope this helps

In solution explorer, right-click References, then click to expand assemblies, find System.IO.Compression.FileSystem and make sure it's checked. Then you can use it in your class - using System.IO.Compression;

The technique I use frequently to simulate a random connection timeout is to use ssh local port forwarding.

ssh -L 12345:realserver.com:80 localhost

This will forward traffic on localhost:12345 to realserver.com:80 You can loop this around in your own local machine as well, if you want:

ssh -L 12345:localhost:8080 localhost

So you can point your application at your localhost and custom port, and the traffic will get routed to the target host:port. Then you can exit out of this shell (you may also need to ctrl+c the shell after you exit) and it will kill the forwarding which causes your app to see a connection loss.

You can also use the element.scrollIntoView() options

el.scrollIntoView(
  { 
    behavior: 'smooth', 
    block: 'start' 
  },
);

which most browsers support

If your action is not idempotent, then you MUST use POST. If you don't, you're just asking for trouble down the line. GET, PUT and DELETE methods are required to be idempotent. Imagine what would happen in your application if the client was pre-fetching every possible GET request for your service – if this would cause side effects visible to the client, then something's wrong.

I agree that sending a POST with a query string but without a body seems odd, but I think it can be appropriate in some situations.

Think of the query part of a URL as a command to the resource to limit the scope of the current request. Typically, query strings are used to sort or filter a GET request (like ?page=1&sort=title) but I suppose it makes sense on a POST to also limit the scope (perhaps like ?action=delete&id=5).

Try this:

>>> i = 3
>>> a = [1, 2, 3, 4]
>>> next(iter(a[i:]), 'fail')
4
>>> next(iter(a[i + 1:]), 'fail')
'fail'

I really wanted this (placeholders should look the same for text boxes as select boxes!) and straight CSS wasn't working in Chrome. Here is what I did:

First make sure your select tag has a .has-prompt class.

Then initialize this class somewhere in document.ready.

# Adds a class to select boxes that have prompt currently selected.
# Allows for placeholder-like styling.
# Looks for has-prompt class on select tag.
Mess.Views.SelectPromptStyler = Backbone.View.extend
  el: 'body'

  initialize: ->
    @$('select.has-prompt').trigger('change')

  events:
    'change select.has-prompt': 'changed'

  changed: (e) ->
    select = @$(e.currentTarget)
    if select.find('option').first().is(':selected')
      select.addClass('prompt-selected')
    else
      select.removeClass('prompt-selected')

Then in CSS:

select.prompt-selected {
  color: $placeholder-color;
}

In at least Postgres, you can use the alias name in the group by clause:

SELECT itemName as ItemName1, substring(itemName, 1,1) as FirstLetter, Count(itemName) FROM table1 GROUP BY ItemName1, FirstLetter;

I wouldn't recommend renaming an alias as a change in capitalization, that causes confusion.

For example summer :

lblSummer.foreColor = color.Yellow;

You start looking near that code that you know ran, and you stop looking when you reach the code you know didn't run.

What you're looking for is probably some place where your program calls a function through a function pointer, but that pointer is null.

It's also possible you have stack corruption. You might have overwritten a function's return address with zero, and the exception occurs at the end of the function. Check for possible buffer overflows, and if you are calling any DLL functions, make sure you used the right calling convention and parameter count.

This isn't an ordinary case of using a null pointer, like an unassigned object reference or PChar. In those cases, you'll have a non-zero "at address x" value. Since the instruction occurred at address zero, you know the CPU's instruction pointer was not pointing at any valid instruction. That's why the debugger can't show you which line of code caused the problem — there is no line of code. You need to find it by finding the code that lead up to the place where the CPU jumped to the invalid address.

The call stack might still be intact, which should at least get you pretty close to your goal. If you have stack corruption, though, you might not be able to trust the call stack.

Try this:

if ( jQuery('#postageyes').is(':checked') ){ ... }

var a = A.parentNode.replaceChild(document.createElement("span"), A);

a is the replaced A element.

To change into another directory use WORKDIR. All the RUN, CMD and ENTRYPOINT commands after WORKDIR will be executed from that directory.

RUN git clone XYZ 
WORKDIR "/XYZ"
RUN make

answer = None
while True:
    answer = raw_input("Do you like pie?")
    if answer in ("yes", "no"): break
    print "That is not a yes or a no"

Would give you what you want with no goto statement.

One easy solution is to use delayed expansion, as this doesn't change any special characters.

set "line=<?xml version="1.0" encoding="utf-8" ?>"
setlocal EnableDelayedExpansion
(
  echo !line!
) > myfile.xml

EDIT : Another solution is to use a disappearing quote.

This technic uses a quotation mark to quote the special characters

@echo off
setlocal EnableDelayedExpansion
set ""="
echo !"!<?xml version="1.0" encoding="utf-8" ?>

The trick works, as in the special characters phase the leading quotation mark in !"! will preserve the rest of the line (if there aren't other quotes).
And in the delayed expansion phase the !"! will replaced with the content of the variable " (a single quote is a legal name!).

If you are working with disabled delayed expansion, you could use a FOR /F loop instead.

for /f %%^" in ("""") do echo(%%~" <?xml version="1.0" encoding="utf-8" ?>

But as the seems to be a bit annoying you could also build a macro.

set "print=for /f %%^" in ("""") do echo(%%~""

%print%<?xml version="1.0" encoding="utf-8" ?>
%print% Special characters like &|<>^ works now without escaping

Use RGBA like this: background-color: rgba(255, 0, 0, .5)

All of these answers miss one important point -- the n'th line is the n'th line in the file, and not the n'th row in the dataset. I have a situation where I download some antiquated stream gauge data from the USGS. The head of the dataset is commented with '#', the first line after that are the labels, next comes a line that describes the date types, and last the data itself. I never know how many comment lines there are, but I know what the first couple of rows are. Example:

----------------------------- WARNING ----------------------------------

Some of the data that you have obtained from this U.S. Geological Survey database

may not have received Director's approval. ... agency_cd site_no datetime tz_cd 139719_00065 139719_00065_cd

5s 15s 20d 6s 14n 10s USGS 08041780 2018-05-06 00:00 CDT 1.98 A

It would be nice if there was a way to automatically skip the n'th row as well as the n'th line.

As a note, I was able to fix my issue with:

import pandas as pd
ds = pd.read_csv(fname, comment='#', sep='\t', header=0, parse_dates=True)
ds.drop(0, inplace=True)

I have used FileSaver.js to save the blob as file.

This is the repo : https://github.com/eligrey/FileSaver.js/

Usage:

import { saveAs } from 'file-saver';

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

saveAs("https://httpbin.org/image", "image.jpg");

When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:

<input type="radio" name="rdb" value="male"/>

then in your php code you need to use:

$rdb_value = $_POST['rdb'];

Thanks to Waseem05 for his Swift 3 translation but his method only worked for me when I wrapped it inside an extension to UIImage and placed it outside/below the parent class like so:

extension UIImage {

        func fixOrientation() -> UIImage
        {

            if self.imageOrientation == UIImageOrientation.up {
            return self
        }

        var transform = CGAffineTransform.identity

        switch self.imageOrientation {
        case .down, .downMirrored:
            transform = transform.translatedBy(x: self.size.width, y: self.size.height)
            transform = transform.rotated(by: CGFloat(M_PI));

        case .left, .leftMirrored:
            transform = transform.translatedBy(x: self.size.width, y: 0);
            transform = transform.rotated(by: CGFloat(M_PI_2));

        case .right, .rightMirrored:
            transform = transform.translatedBy(x: 0, y: self.size.height);
            transform = transform.rotated(by: CGFloat(-M_PI_2));

        case .up, .upMirrored:
            break
        }


        switch self.imageOrientation {

        case .upMirrored, .downMirrored:
            transform = transform.translatedBy(x: self.size.width, y: 0)
            transform = transform.scaledBy(x: -1, y: 1)

        case .leftMirrored, .rightMirrored:
            transform = transform.translatedBy(x: self.size.height, y: 0)
            transform = transform.scaledBy(x: -1, y: 1);

        default:
            break;
        }

        // Now we draw the underlying CGImage into a new context, applying the transform
        // calculated above.
        let ctx = CGContext(
            data: nil,
            width: Int(self.size.width),
            height: Int(self.size.height),
            bitsPerComponent: self.cgImage!.bitsPerComponent,
            bytesPerRow: 0,
            space: self.cgImage!.colorSpace!,
            bitmapInfo: UInt32(self.cgImage!.bitmapInfo.rawValue)
        )



        ctx!.concatenate(transform);

        switch self.imageOrientation {

        case .left, .leftMirrored, .right, .rightMirrored:
            // Grr...
            ctx?.draw(self.cgImage!, in: CGRect(x:0 ,y: 0 ,width: self.size.height ,height:self.size.width))

        default:
            ctx?.draw(self.cgImage!, in: CGRect(x:0 ,y: 0 ,width: self.size.width ,height:self.size.height))
            break;
        }

        // And now we just create a new UIImage from the drawing context
        let cgimg = ctx!.makeImage()

        let img = UIImage(cgImage: cgimg!)

        return img;

    }
}

Then called it with:

let correctedImage:UIImage = wonkyImage.fixOrientation()

And all was then well! Apple should make it easier to discard orientation when we don't need front/back camera and up/down/left/right device orientation metadata.

Try Collections.shuffle(list).If usage of this method is barred for solving the problem, then one can look at the actual implementation.

I understand this question is for sql server 2012, but if the same scenario for SQL Server 2017 or SQL Azure you can use Trim directly as below:

UPDATE *tablename*
   SET *columnname* = trim(*columnname*);

OBJECT vs. EMBED - why not always use embed?

Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not.

object is the current standard tag to embed something on a page. embed was included by Netscape (along img) before anything like object were on the w3c mind.

This is how you include a PDF with object:

<object data="data/test.pdf" type="application/pdf" width="300" height="200">
  alt : <a href="data/test.pdf">test.pdf</a>
</object>

If you really need the inline PDF to show in almost every browser, as older browsers understand embed but not object, you'll need to do this:

<object data="abc.pdf" type="application/pdf">
    <embed src="abc.pdf" type="application/pdf" />
</object>

This version does not validate.

This is not a direct answer to the question. Rather it answers this question: "How do I choose a specific function output from many possible options?".

If you are able to write the function (ie, it is not in a library you cannot modify), then add an input argument that indicates what you want out of the function. Make it a named argument with a default value so in the "common case" you don't even have to specify it.

    def fancy_function( arg1, arg2, return_type=1 ):
        ret_val = None
        if( 1 == return_type ):
            ret_val = arg1 + arg2
        elif( 2 == return_type ):
            ret_val = [ arg1, arg2, arg1 * arg2 ]
        else:
            ret_val = ( arg1, arg2, arg1 + arg2, arg1 * arg2 ) 
        return( ret_val )

This method gives the function "advanced warning" regarding the desired output. Consequently it can skip unneeded processing and only do the work necessary to get your desired output. Also because Python does dynamic typing, the return type can change. Notice how the example returns a scalar, a list or a tuple... whatever you like!

i found this way useful also.

import tkinter.filedialog
from_filename = tkinter.filedialog.askopenfilename()  

here a window will appear so you can browse till you find the file , you click on it then you can continue using open , and read .

from_file = open(from_filename, 'r')
contents = from_file.read()
contents

To get the index values as a list/list of tuples for Index/MultiIndex do:

df.index.values.tolist()  # an ndarray method, you probably shouldn't depend on this

or

list(df.index.values)  # this will always work in pandas

It's better, if you use two div containers in HTML .

As Shown Below:

HTML:

<div id="container1">
    <div id="container2">
        // Content here
    </div>
</div>

CSS:

 #container1{
    height: 100%;
    width: 100%;
    overflow: hidden;
}

 #container2{
    height: 100%;
    width: 100%;
    overflow: auto;
    padding-right: 20px;
}

A try block has just one mandatory clause: The try statement. The except, else and finally clauses are optional and based on user preference.

finally: Before Python leaves the try statement, it will run the code in the finally block under any conditions, even if it's ending the program. E.g., if Python ran into an error while running code in the except or else block, the finally block will still be executed before stopping the program.

boolean atLeastTwo(boolean a, boolean b, boolean c) 
{
  return ((a && b) || (b && c) || (a && c));
}

In case someone needs a CSS background with different color repeating horizontal stripes, here is how I managed to achieve this:

It's actually not really clearly stated in the standard (RFC 3986) whether a percent-encoded version of . or .. is supposed to have the same this-folder/up-a-folder meaning as the unescaped version. Section 3.3 only talks about “The path segments . and ..”, without clarifying whether they match . and .. before or after pct-encoding.

Personally I find Firefox's interpretation that %2E does not mean . most practical, but unfortunately all the other browsers disagree. This would mean that you can't have a path component containing only . or ...

I think the only possible suggestion is “don't do that”! There are other path components that are troublesome too, typically due to server limitations: %2F, %00 and %5C sequences in paths may also be blocked by some web servers, and the empty path segment can also cause problems. So in general it's not possible to fit all possible byte sequences into a path component.

I had this problem and all I had to do is return true from touchend and the warning went away.

You can check whether the connection was lost or not by using this function:-

var socket = io( /**connection**/ );
socket.on('disconnect', function(){

Hope it will help you.

You can use fuckit module.
Wrap your code in a function with @fuckit decorator:

@fuckit
def func():
    code a
    code b #if b fails, it should ignore, and go to c.
    code c #if c fails, go to d

myCollection.ToDictionary(x => x.PartNumber, x => x.PartDescription, StringComparer.OrdinalIgnoreCase)

Just make a new folder inside C:\xampp\htdocs like C:\xampp\htdocs\test and place your index.php or whatever file in it. Access it by browsing localhost/test/

Good luck!

I had the same problem and I figured it out. To make life much simpler, I wrote an util class to handle runtime permissions.

public class PermissionUtil {
    /*
    * Check if version is marshmallow and above.
    * Used in deciding to ask runtime permission
    * */
    public static boolean shouldAskPermission() {
        return (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M);
    }
private static boolean shouldAskPermission(Context context, String permission){
        if (shouldAskPermission()) {
            int permissionResult = ActivityCompat.checkSelfPermission(context, permission);
            if (permissionResult != PackageManager.PERMISSION_GRANTED) {
                return true;
            }
        }
        return false;
    }
public static void checkPermission(Context context, String permission, PermissionAskListener listener){
/*
        * If permission is not granted
        * */
        if (shouldAskPermission(context, permission)){
/*
            * If permission denied previously
            * */
            if (((Activity)context).shouldShowRequestPermissionRationale(permission)) {
                listener.onPermissionPreviouslyDenied();
            } else {
                /*
                * Permission denied or first time requested
                * */
if (PreferencesUtil.isFirstTimeAskingPermission(context, permission)) {
                    PreferencesUtil.firstTimeAskingPermission(context, permission, false);
                    listener.onPermissionAsk();
                } else {
                    /*
                    * Handle the feature without permission or ask user to manually allow permission
                    * */
                    listener.onPermissionDisabled();
                }
            }
        } else {
            listener.onPermissionGranted();
        }
    }
/*
    * Callback on various cases on checking permission
    *
    * 1.  Below M, runtime permission not needed. In that case onPermissionGranted() would be called.
    *     If permission is already granted, onPermissionGranted() would be called.
    *
    * 2.  Above M, if the permission is being asked first time onPermissionAsk() would be called.
    *
    * 3.  Above M, if the permission is previously asked but not granted, onPermissionPreviouslyDenied()
    *     would be called.
    *
    * 4.  Above M, if the permission is disabled by device policy or the user checked "Never ask again"
    *     check box on previous request permission, onPermissionDisabled() would be called.
    * */
    public interface PermissionAskListener {
/*
        * Callback to ask permission
        * */
        void onPermissionAsk();
/*
        * Callback on permission denied
        * */
        void onPermissionPreviouslyDenied();
/*
        * Callback on permission "Never show again" checked and denied
        * */
        void onPermissionDisabled();
/*
        * Callback on permission granted
        * */
        void onPermissionGranted();
    }
}

And the PreferenceUtil methods are as follows.

public static void firstTimeAskingPermission(Context context, String permission, boolean isFirstTime){
SharedPreferences sharedPreference = context.getSharedPreferences(PREFS_FILE_NAME, MODE_PRIVATE;
 sharedPreference.edit().putBoolean(permission, isFirstTime).apply();
 }
public static boolean isFirstTimeAskingPermission(Context context, String permission){
return context.getSharedPreferences(PREFS_FILE_NAME, MODE_PRIVATE).getBoolean(permission, true);
}

Now, all you need is to use the method * checkPermission* with proper arguments.

Here is an example,

PermissionUtil.checkPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    new PermissionUtil.PermissionAskListener() {
                        @Override
                        public void onPermissionAsk() {
                            ActivityCompat.requestPermissions(
                                    thisActivity,
              new String[]{Manifest.permission.READ_CONTACTS},
                            REQUEST_EXTERNAL_STORAGE
                            );
                        }
@Override
                        public void onPermissionPreviouslyDenied() {
                       //show a dialog explaining permission and then request permission
                        }
@Override
                        public void onPermissionDisabled() {
Toast.makeText(context, "Permission Disabled.", Toast.LENGTH_SHORT).show();
                        }
@Override
                        public void onPermissionGranted() {
                            readContacts();
                        }
                    });

how does my app know whether the user has checked the "Never ask again"?

If user checked Never ask again, you'll get callback on onPermissionDisabled.

Happy coding :)

Do a GROUP BY after the ORDER BY by wrapping your query with the GROUP BY like this:

SELECT t.* FROM (SELECT * FROM table ORDER BY time DESC) t GROUP BY t.from

I had this problem when having a Nginx server that exposing the node-js application to the external world. The Nginx made the file (css, js, ...) compressed with gzip and with Chrome it looked like the same.

The problem solved when we found that the node-js server is also compressed the content with gzip. In someway, this double compressing leading to this problem. Canceling node-js compression solved the issue.

For reference and adding to answers citing mefa, it might worth to take a look on the implementation of mefa::rep.data.frame() in case you don't want to include the whole package:

> data <- data.frame(a=letters[1:3], b=letters[4:6])
> data
  a b
1 a d
2 b e
3 c f
> as.data.frame(lapply(data, rep, 2))
  a b
1 a d
2 b e
3 c f
4 a d
5 b e
6 c f

EDIT 2

• For all object changes that need reactivity use Vue.set(object, prop, value)
• For array mutations, you can look at the currently supported list here

EDIT 1

For vuex you will want to do Vue.set(state.object, key, value)

Original

So just for others who come to this question. It appears at some point in Vue 2.* they removed this.items.$set(index, val) in favor of this.$set(this.items, index, val).

Splice is still available and here is a link to array mutation methods available in vue link.

4 spaces do the trick even inside definition list:

Endpoint
: `/listAgencies`

Method
: `GET`

Arguments
:   * `level` - bla-bla.
    * `withDisabled` - should we include disabled `AGENT`s.
    * `userId` - bla-bla.

I am documenting API using BitBucket Wiki and Markdown proprietary extension for definition list is most pleasing (MD's table syntax is awful, imaging multiline and embedding requirements...).

Like this

<a href="www.yoursite.com/theThingYouWantToDownload">Link name</a>

So a file name.jpg on a site example.com would look like this

<a href="www.example.com/name.jpg">Image</a>

You should check it against null.

If you want to check if object x is null or not, you can do:

    if(x != null)

But if it is not null, it can have properties which are null or empty. You will check those explicitly:

    if(x.getProperty() != null)

For "empty" check, it depends on what type is involved. For a Java String, you usually do:

    if(str != null && !str.isEmpty())

As you haven't mentioned about any specific problem with this, difficult to tell.

You must make sure your requests module is not being installed in a more recent version of python.

When using python 3.7, run your python file like:

python3 myfile.py

or enter python interactive mode with:

python3

Yes, this works for me. Run your file like this: python3 file.py

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

I wrote a wrapper, that will cache text surfaces, only re-render when dirty. googlecode/ninmonkey/nin.text/demo/

This worked for me

var dateToFormat = "2018-05-16 12:57:13"; //TIMESTAMP

moment(dateToFormat).format("DD/MM/YYYY"); // you get "16/05/2018"

Recovering from Repository Corruption is the official answer.

The really short answer is: find uncorrupted objects and copy them.

Static files should be served from resources, not from controller.

Spring Boot will automatically add static web resources located within any of the following directories:

/META-INF/resources/  
/resources/  
/static/  
/public/

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

    image = (ImageView) findViewById(R.id.imageID);
    MarginLayoutParams marginParams = new MarginLayoutParams(image.getLayoutParams());
    marginParams.setMargins(left_margin, top_margin, right_margin, bottom_margin);
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
    image.setLayoutParams(layoutParams);

This solution works if you're using chrome (can't verify other browsers) and if the text is located in the same DOM Element:

window.getSelection().anchorNode.textContent.substring(
  window.getSelection().extentOffset, 
  window.getSelection().anchorOffset)
