Try any one of the below. These should work:

int a = Character.getNumericValue('3');
int a = Integer.parseInt(String.valueOf('3');

Seems a current version of the purrr (0.2.2) package is the fastest solution:

by_row(x, function(v) list(v)[[1L]], .collate = "list")$.out

Let's compare the most interesting solutions:

data("Batting", package = "Lahman")
x <- Batting[1:10000, 1:10]
library(benchr)
library(purrr)
benchmark(
    split = split(x, seq_len(.row_names_info(x, 2L))),
    mapply = .mapply(function(...) structure(list(...), class = "data.frame", row.names = 1L), x, NULL),
    purrr = by_row(x, function(v) list(v)[[1L]], .collate = "list")$.out
)

Rsults:

Also we can get the same result with Rcpp:

#include <Rcpp.h>
using namespace Rcpp;

// [[Rcpp::export]]
List df2list(const DataFrame& x) {
    std::size_t nrows = x.rows();
    std::size_t ncols = x.cols();
    CharacterVector nms = x.names();
    List res(no_init(nrows));
    for (std::size_t i = 0; i < nrows; ++i) {
        List tmp(no_init(ncols));
        for (std::size_t j = 0; j < ncols; ++j) {
            switch(TYPEOF(x[j])) {
                case INTSXP: {
                    if (Rf_isFactor(x[j])) {
                        IntegerVector t = as<IntegerVector>(x[j]);
                        RObject t2 = wrap(t[i]);
                        t2.attr("class") = "factor";
                        t2.attr("levels") = t.attr("levels");
                        tmp[j] = t2;
                    } else {
                        tmp[j] = as<IntegerVector>(x[j])[i];
                    }
                    break;
                }
                case LGLSXP: {
                    tmp[j] = as<LogicalVector>(x[j])[i];
                    break;
                }
                case CPLXSXP: {
                    tmp[j] = as<ComplexVector>(x[j])[i];
                    break;
                }
                case REALSXP: {
                    tmp[j] = as<NumericVector>(x[j])[i];
                    break;
                }
                case STRSXP: {
                    tmp[j] = as<std::string>(as<CharacterVector>(x[j])[i]);
                    break;
                }
                default: stop("Unsupported type '%s'.", type2name(x));
            }
        }
        tmp.attr("class") = "data.frame";
        tmp.attr("row.names") = 1;
        tmp.attr("names") = nms;
        res[i] = tmp;
    }
    res.attr("names") = x.attr("row.names");
    return res;
}

Now caompare with purrr:

benchmark(
    purrr = by_row(x, function(v) list(v)[[1L]], .collate = "list")$.out,
    rcpp = df2list(x)
)

You can't have ngFor and ngIf on the same element. What you could do is hold off on populating the array you're using in ngFor until the toggle in your example is clicked.

Here's a basic (not great) way you could do it: http://plnkr.co/edit/Pylx5HSWIZ7ahoC7wT6P

you do not need a framework to achieve dependency injection. You can do this by core java concepts as well. http://en.wikipedia.org/wiki/Dependency_injection#Code_illustration_using_Java

This depends on what you mean by "get the range of selection". If you mean getting the range address (like "A1:B1") then use the Address property of Selection object - as Michael stated Selection object is much like a Range object, so most properties and methods works on it.

Sub test()
    Dim myString As String
    myString = Selection.Address
End Sub

this is new function so you have to add other lib file after jQuery lib

<script src="http://malsup.github.com/jquery.form.js"></script>

it will work.. I have tested.. hope it will work for you..

I would use the "Responsive Design View" available under Tools -> Web Developer -> Responsive Design View. It will let you test your CSS against different screen sizes.

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)

Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....

However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.

As you're partially working on Linux and Windows, make sure core.eol is set to native and core.autocrlf is set to true.

Then, replace the content of your .gitattributes file with the following

* text=auto

This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.

However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.

Provided you work on a C based image processing project, replace the content of your .gitattributes file with the following

* text=auto
*.txt text
*.c text
*.h text
*.jpg binary

This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.

In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.

As a real world example, you can also peek at this commit where those changes to a .gitattributes file are demonstrated.

UPDATE to the answer considering the following comment

I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory

Makes sense. Thanks for the clarification. In this specific context, the .gitattributes file by itself won't be enough.

Run the following commands against your repository

$ git config core.eol lf
$ git config core.autocrlf input

As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol will make sure text files bear LF line endings on checkouts. core.autocrlf will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.

Optionally, you can help Git distinguish what is a text file by creating a .gitattributes file containing something similar to the following:

# Autodetect text files
* text=auto

# ...Unless the name matches the following
# overriding patterns

# Definitively text files 
*.txt text
*.c text
*.h text

# Ensure those won't be messed up with
*.jpg binary
*.data binary

If you decided to create a .gitattributes file, commit it.

Lastly, ensure git status mentions "nothing to commit (working directory clean)", then perform the following operation

$ git checkout-index --force --all

This will recreate your files in your working directory, taking into account your config changes and the .gitattributes file and replacing any potential overlooked CRLF in your text files.

Once this is done, every text file in your working directory WILL bear LF line endings and git status should still consider the workdir as clean.

If it is going to be a web based application, you can also use the ServletContextListener interface.

public class SLF4JBridgeListener implements ServletContextListener {

   @Autowired 
   ThreadPoolTaskExecutor executor;

   @Autowired 
   ThreadPoolTaskScheduler scheduler;

    @Override
    public void contextInitialized(ServletContextEvent sce) {

    }

    @Override
    public void contextDestroyed(ServletContextEvent sce) {
         scheduler.shutdown();
         executor.shutdown();     

    }

}

function NumberConvertToDecimal (number) {
    if (number == 0) {
       return '0.00'; 
    }
    number = parseFloat(number);
    number = number.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1");
    number = number.split('.').join('*').split('*').join('.');
    return number;
}

There is no platform independent way to do it.

The nearest thing you can do is to run the code without optimizations. That way you can attach to the process (using the visual c++ debugger or GDB) and get a usable stack trace.

The tag set depends on the corpus that was used to train the tagger. The default tagger of nltk.pos_tag() uses the Penn Treebank Tag Set.

In NLTK 2, you could check which tagger is the default tagger as follows:

import nltk
nltk.tag._POS_TAGGER
>>> 'taggers/maxent_treebank_pos_tagger/english.pickle'

That means that it's a Maximum Entropy tagger trained on the Treebank corpus.

nltk.tag._POS_TAGGER does not exist anymore in NLTK 3 but the documentation states that the off-the-shelf tagger still uses the Penn Treebank tagset.

It seems that the navigation controller looks for

previousViewController.navigationItem.title

If nothing there it looks for

previousViewController.title

This will search text in all the td's inside each tr and show/hide tr's based on search text

 $.each($(".table tbody").find("tr"), function () {                              

                if ($(this).text().toLowerCase().replace(/\s+/g, '').indexOf(searchText.replace(/\s+/g, '').toLowerCase()) == -1)
                    $(this).hide();
                else
                    $(this).show();
 });

Here is the complete procedure for IDEA IntelliJ 2019.3:

1. File > Project Structure

2. Under Project Settings > Modules

3. Under 'Sources' tab, right-click on 'src' folder and select 'Sources'.

4. Apply changes.

----------------WARM server.

step 1: go to cmd go to directory C:\wamp\bin\mysql\mysql5.6.17 hold Shift + right click (choose "open command window here")

step 2: C:\wamp\bin\mysql\mysql5.6.17\bin>mysql -u root -p SellProduct < D:\file.sql

in this case
+ Root is username database  
+ SellProduct is name database.
+ D:\file.sql is file you want to import

---------------It's work with me -------------------

A few key changes to Daniel Galasko's answer fixed all my problems. Unfortunately, I don't have enough reputation to comment directly (yet).

In step 1, when using Auto Layout, simply add a single parent UIView to the cell. EVERYTHING inside the cell must be a subview of the parent. That answered all of my problems. While Xcode adds this for UITableViewCells automatically, it doesn't (but it should) for UICollectionViewCells. According to the docs:

To configure the appearance of your cell, add the views needed to present the data item’s content as subviews to the view in the contentView property. Do not directly add subviews to the cell itself.

Then skip step 3 entirely. It isn't needed.

A flow chart details the processes to follow. A DFD details the flow of data through a system.

In a flow chart, the arrows represent transfer of control (not data) between elements and the elements are instructions or decision (or I/O, etc).

In a DFD, the arrows are actually data transfer between the elements, which are themselves parts of a system.

Wikipedia has a good article on DFDs here.

For me put variable before calling did the trick:

OPENSSL_CONF=/usr/ssl/openssl.cnf openssl req -new -x509 -key privatekey.pem -out publickey.cer -days 365

I have put the following down. It's not totally foolproof though.

import os

dirname = 'create/me'

try:
    os.makedirs(dirname)
except OSError:
    if os.path.exists(dirname):
        # We are nearly safe
        pass
    else:
        # There was an error on creation, so make sure we know about it
        raise

Now as I say, this is not really foolproof, because we have the possiblity of failing to create the directory, and another process creating it during that period.

you can replace your pattern with

regex = ur"\[P\]([\w\s]+)\[\/P\]"

EDIT (after comment): the below will solve the coding issue, but is highly not recommended to use this approach because a linear regression model is a very poor classifier, which will very likely not separate the classes correctly.

Read the well written answer below by @desertnaut, explaining why this error is an hint of something wrong in the machine learning approach rather than something you have to 'fix'.

accuracy_score(y_true, y_pred.round(), normalize=False)

POSIX is a family of standards, specified by the IEEE, to clarify and make uniform the application programming interfaces (and ancillary issues, such as commandline shell utilities) provided by Unix-y operating systems. When you write your programs to rely on POSIX standards, you can be pretty sure to be able to port them easily among a large family of Unix derivatives (including Linux, but not limited to it!); if and when you use some Linux API that's not standardized as part of Posix, you will have a harder time if and when you want to port that program or library to other Unix-y systems (e.g., MacOSX) in the future.

Look in the file Microsoft.Common.targets

The answer to the question is in the file Microsoft.Common.targets for your target framework version.

For .Net Framework version 4.0 (and 4.5 !) the AssemblySearchPaths-element is defined like this:

    <!--
    The SearchPaths property is set to find assemblies in the following order:

        (1) Files from current project - indicated by {CandidateAssemblyFiles}
        (2) $(ReferencePath) - the reference path property, which comes from the .USER file.
        (3) The hintpath from the referenced item itself, indicated by {HintPathFromItem}.
        (4) The directory of MSBuild's "target" runtime from GetFrameworkPath.
            The "target" runtime folder is the folder of the runtime that MSBuild is a part of.
        (5) Registered assembly folders, indicated by {Registry:*,*,*}
        (6) Legacy registered assembly folders, indicated by {AssemblyFolders}
        (7) Resolve to the GAC.
        (8) Treat the reference's Include as if it were a real file name.
        (9) Look in the application's output folder (like bin\debug)
    -->
<AssemblySearchPaths Condition=" '$(AssemblySearchPaths)' == ''">
  {CandidateAssemblyFiles};
  $(ReferencePath);
  {HintPathFromItem};
  {TargetFrameworkDirectory};
  {Registry:$(FrameworkRegistryBase),$(TargetFrameworkVersion),$(AssemblyFoldersSuffix)$(AssemblyFoldersExConditions)};
  {AssemblyFolders};
  {GAC};
  {RawFileName};
  $(OutDir)
</AssemblySearchPaths>

For .Net Framework 3.5 the definition is the same, but the comment is wrong. The 2.0 definition is slightly different, it uses $(OutputPath) instead of $(OutDir).

On my machine I have the following versions of the file Microsoft.Common.targets:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets

This is with Visual Studio 2008, 2010 and 2013 installed on Windows 7.

The fact that the output directory is searched can be a bit frustrating (as the original poster points out) because it may hide an incorrect HintPath. The solution builds OK on your local machine, but breaks when you build on in a clean folder structure (e.g. on the build machine).

There are a couple of options:

• You can use line-height and make sure it is tall as the containing element
• Use display: table-cell and vertical align: middle

My preferred option would be the first one, if it's a short space, or the latter otherwise.

In My Case I had a UILabel under the UITableView in view hierarchy.

I moved it "forward" and the blank space appeared. Not sure why but it works like this, if theres anything under the tableView, it hides the blank space.

Also you can try checking/uncheking "Adjust Scroll View Insets" on your view controller inspector on storyboard.

$(function() {
    $("#show-background").click(function () {
        $("#content-area").animate({opacity: 'toggle'}, 'slow'); 
    });

    var text = $('#show-background').text();
    $('#show-background').text(
        text == "Show Background" ? "Show Text" : "Show Background");
});

Toggle hides or shows elements. You could achieve the same effect using toggle by having 2 links and toggling them when either is clicked.

If you don't mind creating an extra date object, you could try:

var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());

I do something very similar to get a date of the current month without the time.

In my case, I couldn't get the error message in my PHP script no matter what I do (error_get_last(), or ini_set('display_errors',1);) don't show the error message

according to this post

The return value from $mail refers only to whether or not your server's mailing system accepted the message for delivery, and does not and can not in any way know whether or not you are providing valid arguments. For example, the return value would be false if sendmail failed to load (e.g. if it wasn't installed properly), but would return true if sendmail loaded properly but the recipient address doesn't exist.

I confirm this because after some failed attempts to use mail() in my PHP scripts, it turns that sendmail was not installed on my machine, however the php.ini variable sendmail_path was /usr/sbin/sendmail -t -i

1- I installed sendmail from my package manager shell> dnf install sendmail

2- I started it shell> service sendmail start

3- Now if any PHP mail() function fails I find the errors of the sendmail program logged under /var/mail/ directory. 1 file per user

For example this snippet is taken from my /var/mail/root file

This code works with integer lists in a recursive way. Looks for the simplest case scenario, which is: list length less than 2. It means the answer is already there and a test is performed to check for the correct answer. If not, a middle value is set and tested to be the correct, if not bisection is performed by calling again the function, but setting middle value as the upper or lower limit, by shifting it to the left or right

def binary_search(intList, intValue, lowValue, highValue):
    if(highValue - lowValue) < 2:
        return intList[lowValue] == intValue or intList[highValue] == intValue
    middleValue = lowValue + ((highValue - lowValue)/2)
    if intList[middleValue] == intValue:
        return True
    if intList[middleValue] > intValue:
        return binary_search(intList, intValue, lowValue, middleValue - 1)
   return binary_search(intList, intValue, middleValue + 1, highValue)

I have tried using php -l and a couple of other tools.

However, the best one in my experience (your mileage may vary, of course) is scheck of pfff toolset. I heard about pfff on Quora (Is there a good PHP lint / static analysis tool?).

You can compile and install it. There are no nice packages (on my Linux Mint Debian system, I had to install the libpcre3-dev, ocaml, libcairo-dev, libgtk-3-dev and libgimp2.0-dev dependencies first) but it should be worth an install.

The results are reported like

$ ~/sw/pfff/scheck ~/code/github/sc/
login-now.php:7:4: CHECK: Unused Local variable $title
go-automatic.php:14:77: CHECK: Use of undeclared variable $goUrl.

A couple of methods that, if the char does not exists, return the original string.

This one cuts the string after the first occurrence of the pivot:

public static string truncateStringAfterChar(string input, char pivot){         
    int index = input.IndexOf(pivot);   
    if(index >= 0) {
        return input.Substring(index + 1);          
    }           
    return input;       
}

This one instead cuts the string after the last occurrence of the pivot:

public static string truncateStringAfterLastChar(string input, char pivot){         
    return input.Split(pivot).Last();   
}

I found that the example I was using had an xml document specification on the first line. I was using a stylesheet I got at this blog entry and the first line was

<?xmlversion="1.0"encoding="utf-8"?>

which was causing the error. When I removed that line, so that the stylesheet started with the line

<xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

my transform worked. By the way, that blog post was the first good, easy-to follow example I have found for trying to get information from the XML definition of an SSIS package, but I did have to modify the paths in the example for my SSIS 2008 packages, so you might too. I also created a version to extract the "flow" from the precedence constraints. My final one looks like this:

    <xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" encoding="utf-8" />
    <xsl:template match="/">
    <xsl:text>From,To~</xsl:text>
    <xsl:text>
</xsl:text>
    <xsl:for-each select="//DTS:PrecedenceConstraints/DTS:PrecedenceConstraint">
      <xsl:value-of select="@DTS:From"/>
      <xsl:text>,</xsl:text>
      <xsl:value-of select="@DTS:To"/>
       <xsl:text>~</xsl:text>
      <xsl:text>
</xsl:text>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

and gave me a CSV with the tilde as my line delimiter. I replaced that with a line feed in my text editor then imported into excel to get a with look at the data flow in the package.

Html:

<div class="outerDiv">
    <div class="innerDiv">Content</div>
</div>

CSS:

.outerDiv{
    background: #000;
    padding: 10px;
 }

 .innerDiv{
     border: 2px dashed #fff;
     min-height: 200px; //adding min-height as there is no content inside

 }

You probably want the isinstance builtin function:

self.data = data if isinstance(data, list) else self.parse(data)

Direct answer: No

But you can simulate reference with wrappers.

And do the following:

void changeString( _<String> str ) {
    str.s("def");
}

void testRef() {
     _<String> abc = new _<String>("abc");
     changeString( abc );
     out.println( abc ); // prints def
}

Out

void setString( _<String> ref ) {
    str.s( "def" );
}
void testOut(){
    _<String> abc = _<String>();
    setString( abc );
    out.println(abc); // prints def
}

And basically any other type such as:

_<Integer> one = new <Integer>(1);
addOneTo( one );

out.println( one ); // May print 2

I wrote a library that extends EditText which supports natively some validation methods and is actually very flexible.

Current, as I write, natively supported (through xml attributes) validation methods are:

1. regexp: for custom regexp
2. numeric: for an only numeric field
3. alpha: for an alpha only field
4. alphaNumeric: guess what?
5. email: checks that the field is a valid email
6. creditCard: checks that the field contains a valid credit card using Luhn Algorithm
7. phone: checks that the field contains a valid phone number
8. domainName: checks that field contains a valid domain name ( always passes the test in API Level < 8 )
9. ipAddress: checks that the field contains a valid ip address webUrl: checks that the field contains a valid url ( always passes the test in API Level < 8 )
10. nocheck: It does not check anything. (Default)

You can check it out here: https://github.com/vekexasia/android-form-edittext

Hope you enjoy it :)

In the page I linked you'll be able to find also an example for email validation. I'll copy the relative snippet here:

I had the same problem using Git to synchronise repositories on my Android phone and laptop. The solution for me was to do a pull instead of a push, as @CharlesBailey suggested.

git push origin master on the Android repository fails for me with the same error messages that @hap497 got because of a push to a nonbare checkout of a repository + working-copy.

git pull droid master on the laptop repository and working-copy works for me. Of course, you need to have previously run something like git remote add droid /media/KINGSTON4GB/notes_repo/.

Try

List<SubProduct> subProducts = new List<SubProduct>(Model.subproduct);

or

List<SubProduct> subProducts = Model.subproducts as List<SubProduct>;

You can change the comment character to something besides # like this:

git config --global core.commentchar "@"

edit: Now I'd say the clearest way to do this is via the platform module, as per the other answer.

At the beginning of your data frame include stringsAsFactors = FALSE to ignore all misunderstandings.

Note that :

typeof $(this) is JQuery object.

and

typeof $(this)[0] is HTMLElement object

then : if you want to apply .val() on HTMLElement , you can add this extension .

HTMLElement.prototype.val=function(v){
   if(typeof v!=='undefined'){this.value=v;return this;}
   else{return this.value}
}

Then :

document.getElementById('myDiv').val() ==== $('#myDiv').val()

And

 document.getElementById('myDiv').val('newVal') ==== $('#myDiv').val('newVal')

????? INVERSE :

Conversely? if you want to add value property to jQuery object , follow those steps :

1. Download the full source code (not minified) i.e: example http://code.jquery.com/jquery-1.11.1.js .

2. Insert Line after L96 , add this code value:"" to init this new prop

3. Search on jQuery.fn.init , it will be almost Line 2747

4. Now , assign a value to value prop : (Before return statment add this.value=jQuery(selector).val())

Enjoy now : $('#myDiv').value

The usual approach is to uppercase the strings or lower case them for the lookups and comparisons. For example:

>>> "hello".upper() == "HELLO".upper()
True
>>> 

//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]

The reason why I add this answer is that I want to explain the relationship of . and text() .

The first thing is when using [], there are only two types of data:

1. [number] to select a node from node-set
2. [bool] to filter a node-set from node-set

In this case, the value is evaluated to boolean by function boolean(), and there is a rule:

Filters are always evaluated with respect to a context.

When you need to compare text() or . with a string "Data", it first uses string() function to transform those to string type, than gets a boolean result.

There are two important rule about string():

1. The string() function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.

   text() is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]. When it is evaluated by string(["Data"]), it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.

2. If you want the string() function to concatenate all child text, you must then pass a single node instead of a node-set.

   For example, we get a node-set ['a', 'b'], you can pass there parent node to string(parent), this will return 'ab', and of cause string(.) in you case will return an concatenated string "Data".

Both way will get same result only when there is a text node.

You can use WebClient to download the html for any url. Once you have the html, you can use a third-party library like HtmlAgilityPack to lookup values in the html as in below code -

public static string GetInnerHtmlFromDiv(string url)
    {
        string HTML;
        using (var wc = new WebClient())
        {
            HTML = wc.DownloadString(url);
        }
        var doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(HTML);
        
        HtmlNode element = doc.DocumentNode.SelectSingleNode("//div[@id='<div id here>']");
        if (element != null)
        {
            return element.InnerHtml.ToString();
        }   
        return null;            
    }

Bootstrap is an HTML, CSS, JS framework with many components that let you create beautiful and modern web sites or web applications very fast.

The following websites contain examples, elements and reusable components that you can integrate into your project using bootstrap framework

bootsnipp.com

startbootstrap.com

bootdey.com

This should do it:

ALTER TABLE test MODIFY locationExpert VARCHAR(120) 

Instead of step="any", which allows for any number of decimal places, use step=".01", which allows up to two decimal places.

It works for me with $(window).focus().

var w;
var src = 'http://pagetoprint';
if (/chrom(e|ium)/.test(navigator.userAgent.toLowerCase())) {
    w = $('<iframe></iframe>');
    w.attr('src', src);
    w.css('display', 'none');
    $('body').append(w);
    w.load(function() {
        w[0].focus();
        w[0].contentWindow.print();
    });
    $(window).focus(function() {
        console.log('After print');
    });
}
else {
    w = window.open(src);
    $(w).unload(function() {
        console.log('After print');
    });
}

Please make sure your code is fine. I too got stuck in this problem once and tried the solution accepted here but in vain. So I wrote my code again. Apparently I was using a custom array list and adding the values from an array. I tried changing the ArrayList to accept the primitive values only and it worked.

The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.

However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub. What if there are multiple jenkins servers that need to access the same gitolite server?

(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)

So in this case you do need to run the Jenkins daemon as a different user.

There are two steps:

Step 1

The main thing is to update the JENKINS_USER environment variable. Here's a patch showing how to change the user to ptran.

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

I cannot get case to work at all. Heres what I have:

logfile="/home/name/public_html/cgi-bin/check.log"

case "$(pidof -x script.pl | wc -w)" in

0)  echo "script not running, Restarting script:     $(date)" >> $logfile
#  ./restart-script.sh
;;
1)  echo "script Running:     $(date)" >> $logfile
;;
*)  echo "Removed duplicate instances of script: $(date)" >> $logfile
 #   kill $(pidof -x ./script.pl | awk '{ $1=""; print $0}')
;;
esac

rem the case action commands for now just to test the script. the above pidof -x command is returning '1', the case statement is returning the results for '0'.

Anyone have any idea where I'm going wrong?

Solved it by adding the following to my BIN/BASH Script: PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Since 2019, Array.prototype.flatMap is good option.

options.flatMap(o => o.assigned ? [o.name] : []);

From the MDN page linked above:

flatMap can be used as a way to add and remove items (modify the number of items) during a map. In other words, it allows you to map many items to many items (by handling each input item separately), rather than always one-to-one. In this sense, it works like the opposite of filter. Simply return a 1-element array to keep the item, a multiple-element array to add items, or a 0-element array to remove the item.

You can cast your timestamp to a date by suffixing it with ::date. Here, in psql, is a timestamp:

# select '2010-01-01 12:00:00'::timestamp;
      timestamp      
---------------------
 2010-01-01 12:00:00

Now we'll cast it to a date:

wconrad=# select '2010-01-01 12:00:00'::timestamp::date;
    date    
------------
 2010-01-01

On the other hand you can use date_trunc function. The difference between them is that the latter returns the same data type like timestamptz keeping your time zone intact (if you need it).

=> select date_trunc('day', now());
       date_trunc

Here's an answer using the latest Bootstrap 4.0.0. This layout is easier using the flexbox and sizing utility classes that are all provided in Bootstrap 4. This layout is possible with very little extra CSS.

#mmenu_screen > .row {
    min-height: 100vh;
}

.flex-fill {
    flex:1 1 auto;
}

<div id="mmenu_screen" class="container-fluid main_container d-flex">
    <div class="row flex-fill">
        <div class="col-sm-6 h-100">
            <div class="row h-50">
                <div class="col-sm-12" id="mmenu_screen--book">
                    <!-- Button for booking -->
                    Booking
                </div>
            </div>
            <div class="row h-50">
                <div class="col-sm-12" id="mmenu_screen--information">
                    <!-- Button for information -->
                    Info
                </div>
            </div>
        </div>
        <div class="col-sm-6 mmenu_screen--direktaction flex-fill">
            <!-- Button for direktaction -->
            Action
        </div>
    </div>
</div>

Demo

The flex-fill and vh-100 classes are included in Bootstrap 4.1 (and later)

You can pass lists just like other types:

l = [1,2,3]

def stuff(a):
   for x in a:
      print a


stuff(l)

This prints the list l. Keep in mind lists are passed as references not as a deep copy.

Also, if you'd like to know global memory rather than node process':

var os = require('os');

os.freemem();
os.totalmem();

Just an update for Mysqli users :

$base= mysqli_connect($dbhost,  $dbuser, $dbpass, $dbbase);

if (mysqli_connect_errno()) 
  die('Could not connect: ' . mysql_error());

$return_arr = array();

if ($result = mysqli_query( $base, $sql )){
    while ($row = mysqli_fetch_assoc($result)) {
    $row_array['id'] = $row['id'];
    $row_array['col1'] = $row['col1'];
    $row_array['col2'] = $row['col2'];

    array_push($return_arr,$row_array);
   }
 }

mysqli_close($base);

echo json_encode($return_arr);

If your HTML contains heavy HTML-contents like iframe's (i.e. facebook-, twitter, instagram-embeds) the real solution is much more difficult, first wrap your HTML:

[htmlContent appendFormat:@"<html>", [[LocalizationStore instance] currentTextDir], [[LocalizationStore instance] currentLang]];
[htmlContent appendFormat:@"<head>"];
[htmlContent appendString:@"<script type=\"text/javascript\">"];
[htmlContent appendFormat:@"    var lastHeight = 0;"];
[htmlContent appendFormat:@"    function updateHeight() { var h = document.getElementById('content').offsetHeight; if (lastHeight != h) { lastHeight = h; window.location.href = \"x-update-webview-height://\" + h } }"];
[htmlContent appendFormat:@"    window.onload = function() {"];
[htmlContent appendFormat:@"        setTimeout(updateHeight, 1000);"];
[htmlContent appendFormat:@"        setTimeout(updateHeight, 3000);"];
[htmlContent appendFormat:@"        if (window.intervalId) { clearInterval(window.intervalId); }"];
[htmlContent appendFormat:@"        window.intervalId = setInterval(updateHeight, 5000);"];
[htmlContent appendFormat:@"        setTimeout(function(){ clearInterval(window.intervalId); window.intervalId = null; }, 30000);"];
[htmlContent appendFormat:@"    };"];
[htmlContent appendFormat:@"</script>"];
[htmlContent appendFormat:@"..."]; // Rest of your HTML <head>-section
[htmlContent appendFormat:@"</head>"];
[htmlContent appendFormat:@"<body>"];
[htmlContent appendFormat:@"<div id=\"content\">"]; // !important https://stackoverflow.com/a/8031442/1046909
[htmlContent appendFormat:@"..."]; // Your HTML-content
[htmlContent appendFormat:@"</div>"]; // </div id="content">
[htmlContent appendFormat:@"</body>"];
[htmlContent appendFormat:@"</html>"];

Then add handling x-update-webview-height-scheme into your shouldStartLoadWithRequest:

    if (navigationType == UIWebViewNavigationTypeLinkClicked || navigationType == UIWebViewNavigationTypeOther) {
    // Handling Custom URL Scheme
    if([[[request URL] scheme] isEqualToString:@"x-update-webview-height"]) {
        NSInteger currentWebViewHeight = [[[request URL] host] intValue];
        if (_lastWebViewHeight != currentWebViewHeight) {
            _lastWebViewHeight = currentWebViewHeight; // class property
            _realWebViewHeight = currentWebViewHeight; // class property
            [self layoutSubviews];
        }
        return NO;
    }
    ...

And finally add the following code inside your layoutSubviews:

    ...
    NSInteger webViewHeight = 0;

    if (_realWebViewHeight > 0) {
        webViewHeight = _realWebViewHeight;
        _realWebViewHeight = 0;
    } else {
        webViewHeight = [[webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"content\").offsetHeight;"] integerValue];
    }

    upateWebViewHeightTheWayYorLike(webViewHeight);// Now your have real WebViewHeight so you can update your webview height you like.
    ...

P.S. You can implement time delaying (SetTimeout and setInterval) inside your ObjectiveC/Swift-code - it's up to you.

P.S.S. Important info about UIWebView and Facebook Embeds: Embedded Facebook post does not shows properly in UIWebView

I'm not sure if it's worth it, but you can emulate Java's named loops with a few simple macros:

#define LOOP_NAME(name) \
    if ([[maybe_unused]] constexpr bool _namedloop_InvalidBreakOrContinue = false) \
    { \
        [[maybe_unused]] CAT(_namedloop_break_,name): break; \
        [[maybe_unused]] CAT(_namedloop_continue_,name): continue; \
    } \
    else

#define BREAK(name) goto CAT(_namedloop_break_,name)
#define CONTINUE(name) goto CAT(_namedloop_continue_,name)

#define CAT(x,y) CAT_(x,y)
#define CAT_(x,y) x##y

Example usage:

#include <iostream>

int main()
{
    // Prints:
    // 0 0
    // 0 1
    // 0 2
    // 1 0
    // 1 1

    for (int i = 0; i < 3; i++) LOOP_NAME(foo)
    {
        for (int j = 0; j < 3; j++)
        {
            std::cout << i << ' ' << j << '\n';
            if (i == 1 && j == 1)
                BREAK(foo);
        }
    }
}

Another example:

#include <iostream>

int main()
{
    // Prints: 
    // 0
    // 1
    // 0
    // 1
    // 0
    // 1

    int count = 3;
    do LOOP_NAME(foo)
    {
        for (int j = 0; j < 3; j++)
        {
            std::cout << ' ' << j << '\n';
            if (j == 1)
                CONTINUE(foo);
        }
    }
    while(count-- > 1);
}

Also, you can do:

b = list(a)

This will work for any sequence, even those that don't support indexers and slices...

No, not quite.

Firstly, there's a slight difference in semantics. If a is null, then a.concat(b) throws a NullPointerException but a+=b will treat the original value of a as if it were null. Furthermore, the concat() method only accepts String values while the + operator will silently convert the argument to a String (using the toString() method for objects). So the concat() method is more strict in what it accepts.

To look under the hood, write a simple class with a += b;

public class Concat {
    String cat(String a, String b) {
        a += b;
        return a;
    }
}

Now disassemble with javap -c (included in the Sun JDK). You should see a listing including:

java.lang.String cat(java.lang.String, java.lang.String);
  Code:
   0:   new     #2; //class java/lang/StringBuilder
   3:   dup
   4:   invokespecial   #3; //Method java/lang/StringBuilder."<init>":()V
   7:   aload_1
   8:   invokevirtual   #4; //Method java/lang/StringBuilder.append:(Ljava/lang/String;)Ljava/lang/StringBuilder;
   11:  aload_2
   12:  invokevirtual   #4; //Method java/lang/StringBuilder.append:(Ljava/lang/String;)Ljava/lang/StringBuilder;
   15:  invokevirtual   #5; //Method java/lang/StringBuilder.toString:()Ljava/lang/    String;
   18:  astore_1
   19:  aload_1
   20:  areturn

So, a += b is the equivalent of

a = new StringBuilder()
    .append(a)
    .append(b)
    .toString();

The concat method should be faster. However, with more strings the StringBuilder method wins, at least in terms of performance.

The source code of String and StringBuilder (and its package-private base class) is available in src.zip of the Sun JDK. You can see that you are building up a char array (resizing as necessary) and then throwing it away when you create the final String. In practice memory allocation is surprisingly fast.

Update: As Pawel Adamski notes, performance has changed in more recent HotSpot. javac still produces exactly the same code, but the bytecode compiler cheats. Simple testing entirely fails because the entire body of code is thrown away. Summing System.identityHashCode (not String.hashCode) shows the StringBuffer code has a slight advantage. Subject to change when the next update is released, or if you use a different JVM. From @lukaseder, a list of HotSpot JVM intrinsics.

Console.WriteLine(decimal.Round(pay,2));

document.querySelectorAll("[data-foo]")

will get you all elements with that attribute.

document.querySelectorAll("[data-foo='1']")

will only get you ones with a value of 1.

If you want to just compare dates,

yourdatetime.date() < datetime.today().date()

Or, obviously,

yourdatetime.date() == datetime.today().date()

If you want to check that they're the same date.

The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about. Unless your question is about a function/module named "snake".

Basically, the datetime module has three types for storing a point in time:

• date for year, month, day of month
• time for hours, minutes, seconds, microseconds, time zone info
• datetime combines date and time. It has the methods date() and time() to get the corresponding date and time objects, and there's a handy combine function to combine date and time into a datetime.

Java <= 6.x just allows you to catch one exception for each catch block:

try {

} catch (ExceptionType name) {

} catch (ExceptionType name) {

}

Documentation:

Each catch block is an exception handler and handles the type of exception indicated by its argument. The argument type, ExceptionType, declares the type of exception that the handler can handle and must be the name of a class that inherits from the Throwable class.

For Java 7 you can have multiple Exception caught on one catch block:

catch (IOException|SQLException ex) {
    logger.log(ex);
    throw ex;
}

Documentation:

In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception.

They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"

For Mac OS, you can use the following -

1. /usr/local/opt/gradle/libexec/ or more generically - path/to/gradle/libexec/ - this is recommended. (the first path is what's achieved after installing gradle via Homebrew)
2. /path/to/android/studio/plugins/gradle - I don't recommend this because this version of Gradle might be out of date, and Android Studio itself might say it's incompatible.

With the help of this post, I create following function with additional length checks

public string ReplaceStringByIndex(string original, string replaceWith, int replaceIndex)
{
    if (original.Length >= (replaceIndex + replaceWith.Length))
    {
        StringBuilder rev = new StringBuilder(original);
        rev.Remove(replaceIndex, replaceWith.Length);
        rev.Insert(replaceIndex, replaceWith);
        return rev.ToString();
    }
    else
    {
        throw new Exception("Wrong lengths for the operation");

You can create a dict and pass this as the data param to the dataframe constructor:

df = pd.DataFrame({'Gene':s.index, 'count':s.values})
df
Out[235]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Alternatively you can create a df from the series, you need to call reset_index as the index will be used and then rename the columns:

In [237]:

df = pd.DataFrame(s).reset_index()
df.columns = ['Gene', 'count']
df
Out[237]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Try vi with the -b option, this will show special end of line characters (I typically use it to see windows line endings in a txt file on a unix OS)

But if you want a scripted solution obviously vi wont work so you can try the -f or -e options with grep and pipe the result into sed or awk. From grep man page:

Matcher Selection -E, --extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). (-E is specified by POSIX.)

   -F, --fixed-strings
          Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.  (-F is specified
          by POSIX.)

var depthead = (from s in db.M_Users
                  join m in db.M_User_Types on s.F_User_Type equals m.UserType_Id
                  where m.UserType_Name.ToUpper().Trim().Contains("DEPARTMENT HEAD")
                  select new {s.FullName,s.F_User_Type,s.userId,s.UserCode } 
               ).OrderBy(d => d.userId).ToList();

Model.AvailableDeptHead.Add(new SelectListItem { Text = "Select", Value = "0" });
for (int i = 0; i < depthead.Count; i++)
    Model.AvailableDeptHead.Add(new SelectListItem { Text = depthead[i].UserCode + " - " + depthead[i].FullName, Value = Convert.ToString(depthead[i].userId) });

For me the error came after changing my password for my AD account.

I had to remove the line from credential manager (which contained the previous password.)

Then it worked again.

#include<stdio.h>
using namespace std;

int main()
{
printf("%s",__DATE__);
printf("%s",__TIME__);

return 0;
}

Try passing it directly to the ng-click function:

<div class="col-lg-1 text-center">
    <span class="glyphicon glyphicon-trash" data="{{event.id}}"
          ng-click="deleteEvent(event.id)"></span>
</div>

Then it should be available in your handler:

$scope.deleteEvent=function(idPassedFromNgClick){
    console.log(idPassedFromNgClick);
}

Here's an example

One-liner solution

import pandas as pd

dict = {row[0] : row[1] for _, row in pd.read_csv("file.csv").iterrows()}

For python 3

First install module:

pip3 install gitpython

and later, code it :)

import os
from git.repo.base import Repo
Repo.clone_from("https://github.com/*****", "folderToSave")

I hope this helps you

shortest way: fping 4.2.2.1 => "4.2.2.1 is alive"

i prefer this as it's faster and less verbose output than ping, downside is you will have to install it.

you can use any public dns rather than a specific website.

fping -q google.com && echo "do something because you're connected!"

-q returns an exit code, so i'm just showing an example of running something you're online.

to install on mac: brew install fping; on ubuntu: sudo apt-get install fping

Oracle views like ALL_TABLES and ALL_CONSTRAINTS have an owner column, which you can use to restrict your query. There are also variants of these tables beginning with USER instead of ALL, which only list objects which can be accessed by the current user.

One of these views should help to solve your problem. They always worked fine for me for similar problems.

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".

An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).

Their perception is different but the moment is the same.

You can find more details in this answer.

UPDATE

OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".

Let's look at your original question code broken down like this:

// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");

// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));

// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());

I haven't run this code but I am certain it will print true and the same number of milliseconds each time:

System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));

System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());

But as you said yourself printing them out as strings will result in "different" time because DateTime applies the time zone. That's why "time" is stored and transferred as Timestamp objects (which basically wraps a long) and displayed or entered as Date[Time].

In your own answer you are artificially adding an offset and creating a "wrong" time. If you use that timestamp to create another DateTime and print it out it will be offset twice.

// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));

P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

The pthread_exit() API

as has been already remarked, is used for the calling thread termination. After a call to that function a complicating clean up mechanism is started. When it completes the thread is terminated. The pthread_exit() API is also called implicitly when a call to the return() routine occurs in a thread created by pthread_create(). Actually, a call to return() and a call to pthread_exit() have the same impact, being called from a thread created by pthread_create().

It is very important to distinguish the initial thread, implicitly created when the main() function starts, and threads created by pthread_create(). A call to the return() routine from the main() function implicitly invokes the exit() system call and the entire process terminates. No thread clean up mechanism is started. A call to the pthread_exit() from the main() function causes the clean up mechanism to start and when it finishes its work the initial thread terminates.

What happens to the entire process (and to other threads) when pthread_exit() is called from the main() function depends on the PTHREAD implementation. For example, on IBM OS/400 implementation the entire process is terminated, including other threads, when pthread_exit() is called from the main() function. Other systems may behave differently. On most modern Linux machines a call to pthread_exit() from the initial thread does not terminate the entire process until all threads termination. Be careful using pthread_exit() from main(), if you want to write a portable application.

The pthread_join() API

is a convenient way to wait for a thread termination. You may write your own function that waits for a thread termination, perhaps more suitable to your application, instead of using pthread_join(). For example, it can be a function based on waiting on conditional variables.

I would recommend for reading a book of David R. Butenhof “Programming with POSIX Threads”. It explains the discussed topics (and more complicated things) very well (although some implementation details, such as pthread_exit usage in the main function, not always reflected in the book).

If you are using IBM RAD, then ensure the to remove any j2ee.jar in your projects build path -> libraries tab, and then click on "add external jar" and select the j2ee.jar that is shipped with RAD.

The first thing you need to know is that HashSet acts like a Set, which means you add your object directly to the HashSet and it cannot contain duplicates. You just add your value directly in HashSet.

However, HashMap is a Map type. That means every time you add an entry, you add a key-value pair.

In HashMap you can have duplicate values, but not duplicate keys. In HashMap the new entry will replace the old one. The most recent entry will be in the HashMap.

Understanding Link between HashMap and HashSet:

Remember, HashMap can not have duplicate keys. Behind the scene HashSet uses a HashMap.

When you attempt to add any object into a HashSet, this entry is actually stored as a key in the HashMap - the same HashMap that is used behind the scene of HashSet. Since this underlying HashMap needs a key-value pair, a dummy value is generated for us.

Now when you try to insert another duplicate object into the same HashSet, it will again attempt to be insert it as a key in the HashMap lying underneath. However, HashMap does not support duplicates. Hence, HashSet will still result in having only one value of that type. As a side note, for every duplicate key, since the value generated for our entry in HashSet is some random/dummy value, the key is not replaced at all. it will be ignored as removing the key and adding back the same key (the dummy value is the same) would not make any sense at all.

Summary:

HashMap allows duplicate values, but not keys. HashSet cannot contains duplicates.

To play with whether the addition of an object is successfully completed or not, you can check the boolean value returned when you call .add() and see if it returns true or false. If it returned true, it was inserted.

I know it's a bit late but I had issues with a modal window not allowing some links on the menu bar to work, even when it has not been triggered. But I solved it by doing the following:

.modal{
display:none;
}

It's simple with some flex and overflow set to hidden.

<!DOCTYPE html>
<html lang="en">
<head>
    <style>
        div {
            height: 150px;
            width: 150px;
            border: 2px solid red;
        
            overflow: hidden;
            display: flex;
            align-items: center;
            justify-content: center;
        }
    </style>
</head>
<body>
    <div>
        <img src="sun.jpg" alt="">
    </div>
</body>
</html>

The ES6 way of require is import. You can export your class and import it somewhere else using import { ClassName } from 'path/to/ClassName'syntax.

import fs from 'fs';
export default class Animal {

  constructor(name){
    this.name = name ;
  }

  print(){
    console.log('Name is :'+ this.name);
  }
}

import Animal from 'path/to/Animal.js';

require 'time'
require 'date'

t = Time.now
d = DateTime.now

dd = DateTime.parse(t.to_s)
tt = Time.parse(d.to_s)

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

BE CAREFUL with those other answers as they will not play properly with bodyParser if you're looking to also support json, urlencoded, etc. To get it to work with bodyParser you should condition your handler to only register on the Content-Type header(s) you care about, just like bodyParser itself does.

To get the raw body content of a request with Content-Type: "text/plain" into req.rawBody you can do:

app.use(function(req, res, next) {
  var contentType = req.headers['content-type'] || ''
    , mime = contentType.split(';')[0];

  if (mime != 'text/plain') {
    return next();
  }

  var data = '';
  req.setEncoding('utf8');
  req.on('data', function(chunk) {
    data += chunk;
  });
  req.on('end', function() {
    req.rawBody = data;
    next();
  });
});

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

First of all, with regards to FormatType.JSON: JSON is not a member of FormatType, it's a possible value of the type. FormatType isn't even a composite type — it's a scalar.

Second, the only way to do this is to create a mapping table. The more common way to do this in Objective-C is to create a series of constants referring to your "symbols", so you'd have NSString *FormatTypeJSON = @"JSON" and so on.

Install 7zip (or download the command line version instead) and use this PowerShell method:

function create-7zip([String] $aDirectory, [String] $aZipfile){
    [string]$pathToZipExe = "$($Env:ProgramFiles)\7-Zip\7z.exe";
    [Array]$arguments = "a", "-tzip", "$aZipfile", "$aDirectory", "-r";
    & $pathToZipExe $arguments;
}

You can the call it like this:

create-7zip "c:\temp\myFolder" "c:\temp\myFolder.zip"

Significant differences between var_dump and print_r

both the functions dumps information about the variable, but var_dump multiple parameters which will be dumped, where as print_r can take two parameters out of which first parameter is the variable you want to dump and second is a boolean value.

var_dump can't return any value it can only dump/print the values where as print_r can return the variable information if we set second parameter of print_r to true. The returned value of print_r will be in string format.

The information printed by print_r is much more in readable format where as var_dump prints raw values.

print_r function can be used in many contexts where as var_dump can be used in debugging purposes mainly since it can't return value.

A char doesn't have any methods - it's a Java primitive. You're looking for the Character wrapper class.

The usage would be:

if(Character.isLetter(ch)) { //... }

In Oracle we can use below.

SELECT * FROM TABLE_A WHERE ASCIISTR(COLUMN_A) <> COLUMN_A;

I've used the below before, and it has worked. It isn't very pretty, but you can alter it to suit your needs.

The following JavaScript function grabs the location.href & document.title for the sharer, and you can ultimately change these.

function fbs_click() {
        u=location.href;
        t=document.title;
window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),
                'sharer',
                'toolbar=0,status=0,width=626,height=436');

            return false;
        }

Usage:

<a rel="nofollow" href="http://www.facebook.com/share.php?u=<;url>" onclick="return fbs_click()" target="_blank">
    Share on Facebook
</a>

It looks like this is what you could possibly be looking for: Facebook sharer title / desc....

Use the following syntax:

  ALTER TABLE your_table
  MODIFY COLUMN column1 datatype,
  MODIFY COLUMN column2 datatype,
  ... ... ... ... ... 
  ... ... ... ... ...

Based on that, your ALTER command should be:

  ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100)

Note that:

1. There are no second brackets around the MODIFY statements.
2. I used two separate MODIFY statements for two separate columns.

This is the standard format of the MODIFY statement for an ALTER command on multiple columns in a MySQL table.

Take a look at the following: http://dev.mysql.com/doc/refman/5.1/en/alter-table.html and Alter multiple columns in a single statement

to close bootstrap modal you can pass 'hide' as option to modal method as follow

$('#modal').modal('hide');

Please take a look at working fiddle here

bootstrap also provide events that you can hook into modal functionality, like if you want to fire a event when the modal has finished being hidden from the user you can use hidden.bs.modal event you can read more about modal methods and events here in Documentation

If non of the above method work, give a id to your close button and trigger click on close button.

Do a reset of the configuration and set the root level to OFF

LogManager.getLogManager().reset();
Logger globalLogger = Logger.getLogger(java.util.logging.Logger.GLOBAL_LOGGER_NAME);
globalLogger.setLevel(java.util.logging.Level.OFF);

Frankly speaking, your case works fine for me!

I'm using Angular 5.

<script type='text/javascript'>
    var base = window.location.href.substring(0, window.location.href.toLowerCase().indexOf('index.aspx'))
    document.write('<base href="' + base + '" />');
</script>

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.
debug1: connect to address 173.194.43.20 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

Tomcat 8:

The following worked for me with tomcat 8.

Add these lines to apache-tomcat-8.0.9/conf/tomcat-users.xml

For Manager:

<role rolename="manager-gui"/>
<user username="admin" password="pass" roles="manager-gui"/>

For Host Manager:

<role rolename="admin-gui"/>
<user username="admin" password="pass" roles="admin-gui"/>

You can sort-of do that with objects, as in the following.

Dim w As New Widget

But not with strings or variants.

I updated to 0.3.0 and had the same issue. I had to end up changing my Gradle version to classpath 'com.android.tools.build:gradle:0.6.1+' and in build.gradle and also changing the distributionUrl to distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-bin.zip in the gradle-wrapper.properties file. Then I did a local import of the Gradle file. That worked for me.

How do I properly compare strings?

char input[40];
char check[40];
strcpy(input, "Hello"); // input assigned somehow
strcpy(check, "Hello"); // check assigned somehow

// insufficient
while (check != input)

// good
while (strcmp(check, input) != 0)
// or 
while (strcmp(check, input))

Let us dig deeper to see why check != input is not sufficient.

In C, string is a standard library specification.

A string is a contiguous sequence of characters terminated by and including the first null character.
C11 §7.1.1 1

input above is not a string. input is array 40 of char.

The contents of input can become a string.

In most cases, when an array is used in an expression, it is converted to the address of its 1st element.

The below converts check and input to their respective addresses of the first element, then those addresses are compared.

check != input   // Compare addresses, not the contents of what addresses reference

To compare strings, we need to use those addresses and then look at the data they point to.
strcmp() does the job. §7.23.4.2

int strcmp(const char *s1, const char *s2);

The strcmp function compares the string pointed to by s1 to the string pointed to by s2.

The strcmp function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to by s1 is greater than, equal to, or less than the string pointed to by s2.

Not only can code find if the strings are of the same data, but which one is greater/less when they differ.

The below is true when the string differ.

strcmp(check, input) != 0

For insight, see Creating my own strcmp() function

If the backup wasn't created in the default location, you can use this T-SQL (run this in SSMS) to find the file path for the most recent backup for all DBs on your SQL Server instance:

SELECT  DatabaseName = x.database_name,
        LastBackupFileName = x.physical_device_name,
        LastBackupDatetime = x.backup_start_date
FROM (  SELECT  bs.database_name,
                bs.backup_start_date,
                bmf.physical_device_name,
                  Ordinal = ROW_NUMBER() OVER( PARTITION BY bs.database_name ORDER BY bs.backup_start_date DESC )
          FROM  msdb.dbo.backupmediafamily bmf
                  JOIN msdb.dbo.backupmediaset bms ON bmf.media_set_id = bms.media_set_id
                  JOIN msdb.dbo.backupset bs ON bms.media_set_id = bs.media_set_id
          WHERE   bs.[type] = 'D'
                  AND bs.is_copy_only = 0 ) x
WHERE x.Ordinal = 1
ORDER BY DatabaseName;

Although I'm sure this won't be accepted as the answer to this very old question, I came here looking for a way to do this and this is how I solved the problem.

I created a demonstration here at codepen.io.

The Html:

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/moment.min.js" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/mckamey/countdownjs/master/countdown.min.js" type="text/javascript"></script>
<script src="https://code.jquery.com/jquery-3.0.0.min.js" type="text/javascript"></script>
<div>
  The time is now: <span class="now"></span>, a timer will go off <span class="duration"></span> at <span class="then"></span>
</div>
<div class="difference">The timer is set to go off <span></span></div>
<div class="countdown"></div>

The Javascript:

var now = moment(); // new Date().getTime();
var then = moment().add(60, 'seconds'); // new Date(now + 60 * 1000);

$(".now").text(moment(now).format('h:mm:ss a'));
$(".then").text(moment(then).format('h:mm:ss a'));
$(".duration").text(moment(now).to(then));
(function timerLoop() {
  $(".difference > span").text(moment().to(then));
  $(".countdown").text(countdown(then).toString());
  requestAnimationFrame(timerLoop);
})();

Output:

The time is now: 5:29:35 pm, a timer will go off in a minute at 5:30:35 pm
The timer is set to go off in a minute
1 minute

Note: 2nd line above updates as per momentjs and 3rd line above updates as per countdownjs and all of this is animated at about ~60FPS because of requestAnimationFrame()

Code Snippet:

Alternatively you can just look at this code snippet:

var now = moment(); // new Date().getTime();_x000D_
var then = moment().add(60, 'seconds'); // new Date(now + 60 * 1000);_x000D_

Requirements:

• CountdownJS: http://countdownjs.org/ (And Rawgit to be able to use countdownjs)
• MomentJS: http://momentjs.com/
• requestAnimationFrame() - use this for animation rather than setInterval().

Optional Requirements:

• jQuery: https://jquery.com/

Additionally here is some light reading about the requestAnimationFrame() pattern:

• http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
• https://css-tricks.com/using-requestanimationframe/

I found the requestAnimationFrame() pattern to be much a more elegant solution than the setInterval() pattern.

What is the return type of the round() method in the snippet?

If this is the Math.round() method, it returns a Long when the input param is Double.

So, you will have to cast the return value:

int a = (int) Math.round(doubleVar);

As of Python 3.6, you can use f-strings:

list_ = [9.0, 0.052999999999999999, 
         0.032575399999999997, 0.010892799999999999, 
         0.055702500000000002, 0.079330300000000006]

print(*[f"{element:.2f}" for element in list_])
#9.00 0.05 0.03 0.01 0.06 0.08

You can use print parameters while keeping code very readable:

print(*[f"{element:.2f}" for element in list_], sep='|', end='<--')
#9.00|0.05|0.03|0.01|0.06|0.08<--

Try to open Visual Studio as admin.

In order for z-index to work, you'll need to give the element a position:absolute or a position:relative property. Once you do that, your links will function properly, though you may have to tweak your CSS a bit afterwards.

This can happen if curl is asked to do plain HTTP on a server that does HTTPS.

Example:

$ curl http://google.com:443
curl: (52) Empty reply from server

Ok. I found the solution here tessnet2 fails to load the Ans given by Adam

Apparently i was using wrong version of tessdata. I was following the the source page instruction intuitively and that caused the problem.

it says

Quick Tessnet2 usage

1. Download binary here, add a reference of the assembly Tessnet2.dll to your .NET project.

2. Download language data definition file here and put it in tessdata directory. Tessdata directory and your exe must be in the same directory.

After you download the binary, when you follow the link to download the language file, there are many language files. but none of them are right version. you need to select all version and go to next page for correct version (tesseract-2.00.eng)! They should either update download binary link to version 3 or put the the version 2 language file on the first page. Or at least bold mention the fact that this version issue is a big deal!

Anyway I found it. Thanks everyone.

i know it is not the best solution, but the only one supposed solution that i have read for all the web is to install chrome cast extension, so, i've decide, not to put the iframe into the website, i just insert the thumnail of my video from youtube like in this post explain.

and here we have two options:
1) Target the video to the channel and play it there
2) Call the video via ajax, like explain here (i've decided for this one) in a colorbox or any another plugin.

and like this, i prevent the google cast sender error make my site slow

colrm x

For example, if you need the first 100 characters:

cat file |colrm 101 

It's been around for years and is in most linux's and bsd's (freebsd for sure), usually by default. I can't remember ever having to type apt-get install colrm.

New way I've just stumbled upon: css calc():

.calculated-width {
    width: -webkit-calc(100% - 100px);
    width:    -moz-calc(100% - 100px);
    width:         calc(100% - 100px);
}?

Source: css width 100% minus 100px

1. Switch to Branch2

   git checkout Branch2
   

2. Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:

   git rebase Branch1
   

Which would leave you with the desired result in Branch2:

a -- b -- c                      <-- Master
           \
            d -- e               <-- Branch1
           \
            d -- e -- f' -- g'   <-- Branch2

You can delete Branch1.

This stratify parameter makes a split so that the proportion of values in the sample produced will be the same as the proportion of values provided to parameter stratify.

For example, if variable y is a binary categorical variable with values 0 and 1 and there are 25% of zeros and 75% of ones, stratify=y will make sure that your random split has 25% of 0's and 75% of 1's.

Option down resolve this problem

I run my compose file:

docker-compose -f docker/docker-compose.yml up -d

then I delete all with down --rmi all

docker-compose -f docker/docker-compose.yml down --rmi all

Stops containers and removes containers, networks, volumes, and images
created by `up`.

By default, the only things removed are:

- Containers for services defined in the Compose file
- Networks defined in the `networks` section of the Compose file
- The default network, if one is used

Networks and volumes defined as `external` are never removed.

Usage: down [options]

Options:
    --rmi type          Remove images. Type must be one of:
                        'all': Remove all images used by any service.
                        'local': Remove only images that don't have a custom tag
                        set by the `image` field.
    -v, --volumes       Remove named volumes declared in the `volumes` section
                        of the Compose file and anonymous volumes

set the system property log4j.debug=true. Then you can determine where your configuration is running amuck.

Install the latest version of TDM-GCC here is the link-http://wiki.codeblocks.org/index.php/MinGW_installation

The reason for this is PHP doesn't recognise utf-8.

Here you can check it for all Special Characters in HTML

You can create a mapping to do this for you.

This one will auto indent the whole file and still keep your cursor in the position you are:

nmap <leader>ai mzgg=G`z

You can add some ALT+Letter shortcuts to the VBA editor environment. I added ALT+C to Comment selected text lines and A+X to Uncomment selected text lines:

1. In the VBE, right-click on a toolbar and select Customize
2. Optionally create a new toolbar
3. Select the Command Tab and 'Edit' in the Categories listbox. Find 'Comment Block' in the Commands listbox. Click and drag it to the target toolbar. Left-click on it to open the context popup menu and select 'Image and Text'. Replace the name with &C.
4. Repeat step 3 for the Uncomment Block command and replace the name with &X.
5. Close the Customize popup window.

There are built-in Alt+Letter commands that cannot be used for new shortcuts using letters: A,D,E,D,H,I,O,Q,R,T,V,W.

Just return any kind of list. ArrayList will be fine, its not static.

    ArrayList<yourClass> list = new ArrayList<yourClass>();
for (yourClass item : yourArray) 
{
   list.add(item); 
}

import os, sys, re, glob

pattern = re.compile(r"\<\[\d\>")
replacementStringMatchesPattern = "<[1>"

for infile in glob.glob(os.path.join(os.getcwd(), '*.txt')):
   for line in reader: 
      retline =  pattern.sub(replacementStringMatchesPattern, "", line)         
      sys.stdout.write(retline)
      print (retline)

to get dynamic height based on browser window. Use vh instead of %

e.g: pass following height: 100vh; to the specific div

Import the spring util namespace. Then you can define a list bean as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                    http://www.springframework.org/schema/util
                    http://www.springframework.org/schema/util/spring-util-2.5.xsd">


<util:list id="myList" value-type="java.lang.String">
    <value>foo</value>
    <value>bar</value>
</util:list>

The value-type is the generics type to be used, and is optional. You can also specify the list implementation class using the attribute list-class.

The angular way is shown in the angular docs :)

https://docs.angularjs.org/api/ng/directive/ngReadonly

Here is the example they use:

<body>
    Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
    <input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>

Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).

So basically in your case you would want to do something like below or check out this working example.

<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>

from tkinter import *
from PIL import ImageTk, Image

window = Tk()
window.geometry("1000x300")

path = "1.jpg"

image = PhotoImage(Image.open(path))

panel = Label(window, image = image)

panel.pack()

window.mainloop()

In my case if i append script tag like this :

var script = document.createElement('script');
script.src = 'url/test.js';
$('head').append($(script));

i get that warning but if i append script tag to head first then change src warning gone !

var script = document.createElement('script');
$('head').append($(script));
script.src = 'url/test.js';

works fine!!

I'll start off with this: consistency is king, the decision is less important than the consistency in your code base.

In C++

NULL is defined as 0 or 0L in C++.

If you've read The C++ Programming Language Bjarne Stroustrup suggests using 0 explicitly to avoid the NULL macro when doing assignment, I'm not sure if he did the same with comparisons, it's been a while since I read the book, I think he just did if(some_ptr) without an explicit comparison but I am fuzzy on that.

The reason for this is that the NULL macro is deceptive (as nearly all macros are) it is actually 0 literal, not a unique type as the name suggests it might be. Avoiding macros is one of the general guidelines in C++. On the other hand, 0 looks like an integer and it is not when compared to or assigned to pointers. Personally I could go either way, but typically I skip the explicit comparison (though some people dislike this which is probably why you have a contributor suggesting a change anyway).

Regardless of personal feelings this is largely a choice of least evil as there isn't one right method.

This is clear and a common idiom and I prefer it, there is no chance of accidentally assigning a value during the comparison and it reads clearly:

if (some_ptr) {}

This is clear if you know that some_ptr is a pointer type, but it may also look like an integer comparison:

if (some_ptr != 0) {}

This is clear-ish, in common cases it makes sense... But it's a leaky abstraction, NULL is actually 0 literal and could end up being misused easily:

if (some_ptr != NULL) {}

C++11 has nullptr which is now the preferred method as it is explicit and accurate, just be careful about accidental assignment:

if (some_ptr != nullptr) {}

Until you are able to migrate to C++0x I would argue it's a waste of time worrying about which of these methods you use, they are all insufficient which is why nullptr was invented (along with generic programming issues which came up with perfect forwarding.) The most important thing is to maintain consistency.

In C

C is a different beast.

In C NULL can be defined as 0 or as ((void *)0), C99 allows for implementation defined null pointer constants. So it actually comes down to the implementation's definition of NULL and you will have to inspect it in your standard library.

Macros are very common and in general they are used a lot to make up for deficiencies in generic programming support in the language and other things as well. The language is much simpler and reliance on the preprocessor more common.

From this perspective I'd probably recommend using the NULL macro definition in C.

This is how to get the html DOM element purely with JS:

var htmlElement = document.getElementsByTagName("html")[0];

or

var htmlElement = document.querySelector("html");

And if you want to use jQuery to get attributes from it...

$(htmlElement).attr(INSERT-ATTRIBUTE-NAME);

If this is in fact a ListObject table (Insert Table from the ribbon) then you can use the table's .DataBodyRange object to get the number of rows and columns. This ignores the header row.

Sub TableTest()

Dim tbl As ListObject
Dim tRows As Long
Dim tCols As Long

Set tbl = ActiveSheet.ListObjects("Table1")  '## modify to your table name.

With tbl.DataBodyRange
    tRows = .Rows.Count
    tCols = .Columns.Count
End With

MsgBox tbl.Name & " contains " & tRows & " rows and " & tCols & " columns.", vbInformation

End Sub

If you need to use the header row, instead of using tbl.DataBodyRange just use tbl.Range.

Yes. Click on the object (textbox, shape, etc.) to select the object and in the Drawing Tools | Format tab, click on Selection Pane in the Arrange group. From there, you'll see names of objects - you can double click (or press F2) on any name and rename it. By deselecting it, it becomes renamed. You can also get to this from the Home tab -> Drawing group -> Arrange drop-down -> Selection pane or by pressing ALT + F10.

To try and answer your main question:

why would you use .append() rather then .after() or vice verses?

When you are manipulating the DOM with jquery the methods you use depend on the result you want and a frequent use is to replace content.

In replacing content you want to .remove() the content and replace it with new content. If you .remove() the existing tag and then try to use .append() it won't work because the tag itself has been removed, whereas if you use .after(), the new content is added 'outside' the (now removed) tag and isn't affected by the previous .remove().

Your case is an extreme one, but here is a solution for others that fits a more common scenario of wanting to style fewer than 4 borders exactly the same.

border: 1px dashed red; border-width: 1px 1px 0 1px;

that is a little shorter, and maybe easier to read than

border-top: 1px dashed red;  border-right: 1px dashed red; border-left: 1px dashed red;

or

border-color: red; border-style: dashed; border-width: 1px 1px 0 1px;

It is not improbable, that programmers looking for python on windows, also use the Python Tools for Visual Studio. In this case it is easy to install additional packages, by taking advantage of the included "Python Environment" Window. "Overview" is selected within the window as default. You can select "Pip" there.

Then you can install numpy without additional work by entering numpy into the seach window. The coresponding "install numpy" instruction is already suggested.

Nevertheless I had 2 easy to solve Problems in the beginning:

• "error: Unable to find vcvarsall.bat": This problem has been solved here. Although I did not find it at that time and instead installed the C++ Compiler for Python.
• Then the installation continued but failed because of an additional inner exception. Installing .NET 3.5 solved this.

Finally the installation was done. It took some time (5 minutes), so don't cancel the process to early.

I got this confusion in one of my project as well and found this post, very helpful. Tried the same in my playground and here is the summary. Hope this helps someone with stored properties and functions of type static, final,class, overriding class vars etc.

class Simple {

    init() {print("init method called in base")}

    class func one() {print("class - one()")}

    class func two() {print("class - two()")}

    static func staticOne() {print("staticOne()")}

    static func staticTwo() {print("staticTwo()")}

    final func yesFinal() {print("yesFinal()")}

    static var myStaticVar = "static var in base"

    //Class stored properties not yet supported in classes; did you mean 'static'?
    class var myClassVar1 = "class var1"

    //This works fine
    class var myClassVar: String {
       return "class var in base"
    }
}

class SubSimple: Simple {
    //Successful override
    override class func one() {
        print("subClass - one()")
    }
    //Successful override
    override class func two () {
        print("subClass - two()")
    }

    //Error: Class method overrides a 'final' class method
    override static func staticOne() {

    }

    //error: Instance method overrides a 'final' instance method
    override final func yesFinal() {

    }

    //Works fine
    override class var myClassVar: String {
        return "class var in subclass"
    }
}

And here is the testing samples:

print(Simple.one())
print(Simple.two())
print(Simple.staticOne())
print(Simple.staticTwo())
print(Simple.yesFinal(Simple()))
print(SubSimple.one())
print(Simple.myStaticVar)
print(Simple.myClassVar)
print(SubSimple.myClassVar)

//Output
class - one()
class - two()
staticOne()
staticTwo()
init method called in base
(Function)
subClass - one()
static var in base
class var in base
class var in subclass

My url is like this http://www.default-search.net/?sid=503 . I want to get 503 . I wrote the following code .

var baseUrl = (window.location).href; // You can also use document.URL
var koopId = baseUrl.substring(baseUrl.lastIndexOf('=') + 1);
alert(koopId)//503

If you use

var v = window.location.pathname;
console.log(v)

You will get only "/";

Nice one, big thanks to Max.

I've wrapped the functionality in his answer into jQuery if anyone wants to use it.

(function($) {
    $.fn.getCursorPosition = function() {
        var input = this.get(0);
        if (!input) return; // No (input) element found
        if ('selectionStart' in input) {
            // Standard-compliant browsers
            return input.selectionStart;
        } else if (document.selection) {
            // IE
            input.focus();
            var sel = document.selection.createRange();
            var selLen = document.selection.createRange().text.length;
            sel.moveStart('character', -input.value.length);
            return sel.text.length - selLen;
        }
    }
})(jQuery);

Scanner sc = new Scanner (System.in)
char c = sc.next().trim().charAt(0);

Actually you can do with VS Code the following:

document.referrer is not the same as the actual URL in all situations.

I have an application where I need to establish a frameset with 2 frames. One frame is known, the other is the page I am linking from. It would seem that document.referrer would be ideal because you would not have to pass the actual file name to the frameset document.

However, if you later change the bottom frame page and then use history.back() it does not load the original page into the bottom frame, instead it reloads document.referrer and as a result the frameset is gone and you are back to the original starting window.

Took me a little while to understand this. So in the history array, document.referrer is not only a URL, it is apparently the referrer window specification as well. At least, that is the best way I can understand it at this time.

If you're using Less, you can use fade(color, 30%).

Use the optional font argument to turtle.write(), from the docs:

turtle.write(arg, move=False, align="left", font=("Arial", 8, "normal"))
 Parameters:

• arg – object to be written to the TurtleScreen
• move – True/False
• align – one of the strings “left”, “center” or right”
• font – a triple (fontname, fontsize, fonttype)

So you could do something like turtle.write("messi fan", font=("Arial", 16, "normal")) to change the font size to 16 (default is 8).

To save your work and exit press Esc and then :wq (w for write and q for quit).

Alternatively, you could both save and exit by pressing Esc and then :x

To set another editor run export EDITOR=myFavoriteEdioron your terminal, where myFavoriteEdior can be vi, gedit, subl(for sublime) etc.

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

Note that you also can use insert in order to put number into the required position within list:

initList = [1,2,3,4,5]
initList.insert(2, 10) # insert(pos, val) => initList = [1,2,10,3,4,5]

And also note that in python you can always get a list length using method len()

I found this one useful. For VB.NET developers:

    Public Shared Function GetFromFileName(ByVal fileName As String) As String
        Return GetFromExtension(Path.GetExtension(fileName).Remove(0, 1))
    End Function

    Public Shared Function GetFromExtension(ByVal extension As String) As String
        If extension.StartsWith("."c) Then
            extension = extension.Remove(0, 1)
        End If

        If MIMETypesDictionary.ContainsKey(extension) Then
            Return MIMETypesDictionary(extension)
        End If

        Return "unknown/unknown"
    End Function

It just associates a semaphore with every object, and uses that.

There is an easy way with Sharpeserializer (open source) :

http://www.sharpserializer.com/

It can directly serialize/de-serialize dictionary.

There is no need to mark your object with any attribute, nor do you have to give the object type in the Serialize method (See here ).

To install via nuget : Install-package sharpserializer

Then it is very simple :

Hello World (from the official website):

// create fake obj
var obj = createFakeObject();

// create instance of sharpSerializer
// with standard constructor it serializes to xml
var serializer = new SharpSerializer();

// serialize
serializer.Serialize(obj, "test.xml");

// deserialize
var obj2 = serializer.Deserialize("test.xml");

I can see some people have asked, so on OSX you can still go to navigate->test or use cmd+shift+T

Remember you have to be focused in the class for this to work

You need to return your promise to the calling function.

islogged:function(){
    var cUid=sessionService.get('uid');
    alert("in loginServce, cuid is "+cUid);
    var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
    $checkSessionServer.then(function(){
        alert("session check returned!");
        console.log("checkSessionServer is "+$checkSessionServer);
    });
    return $checkSessionServer; // <-- return your promise to the calling function
}

To do this in any ES5-compatible environment, such as Node, Chrome, IE 9+, Firefox 4+, or Safari 5+:

Object.keys(obj).length

• Browser compatibility
• Object.keys documentation (includes a method you can add to non-ES5 browsers)

I had the exact same issue. The following thread helped me solve it. Just set your Compile SDK version to Android P.

https://stackoverflow.com/a/49172361/1542720

I fixed this issue by selecting:

API 27+: Android API 27, P preview (Preview)

in the project structure settings. the following image shows my settings. The 13 errors that were coming while building the app, have disappeared.

• Elasticsearch will assign the entire heap specified in jvm.options via the Xms (minimum heap size) and Xmx (maximum heap size) settings.
  • -Xmx12g
  • -Xmx12g
• Set the minimum heap size (Xms) and maximum heap size (Xmx) to be equal to each other.

• Don’t set Xmx to above the cutoff that the JVM uses for compressed object pointers (compressed oops), the exact cutoff varies but is near 32 GB.

• It is also possible to set the heap size via an environment variable

Java 1.5 introduced the Scanner class for handling input from file and streams.

It is used for getting integers from a file and would look something like this:

List<Integer> integers = new ArrayList<Integer>();
Scanner fileScanner = new Scanner(new File("c:\\file.txt"));
while (fileScanner.hasNextInt()){
   integers.add(fileScanner.nextInt());
}

Check the API though. There are many more options for dealing with different types of input sources, differing delimiters, and differing data types.

My worry is if I say delete evertything with an ID (>79 AND < 296) then it may literally wipe the whole table...

That wont happen because you will have a where clause. What happens is that, if you have a statement like delete * from Table1 where id between 70 and 1296 , the first thing that sql query processor will do is to scan the table and look for those records in that range and then apply a delete.

The solution for this question is here https://docops.ca.com/devtest-solutions/8-0-2/en/installing/setting-up-the-mobile-testing-environment/preinstallation-steps-for-mobile-testing/

Please follow this steps, and solve your problem.

The Android SDK package contains a component called compile tools. The mobile test requires at least version 19.0.1, 19.1.0 or 20.0.0.

If these versions are not installed with your ADT package, you may receive an error message when creating a mobile asset in the DevTest Workstation:

SELECT COUNT(job_id) FROM jobs WHERE posted_date < NOW()-30;

Now() returns the current Date and Time.

This is an old question, but no one responded to the question regarding centering text in a terminal.

/**
 * Centers a string of text in a terminal window
 *
 * @param string $text The text to center
 * @param string $pad_string If set, the string to pad with (eg. '=' for a nice header)
 *
 * @return string The padded result, ready to echo
 */
function center($text, $pad_string = ' ') {
    $window_size = (int) `tput cols`;
    return str_pad($text, $window_size, $pad_string, STR_PAD_BOTH)."\n";
}

echo center('foo');
echo center('bar baz', '=');

See the isDigit(char ch) method:

https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Character.html

and pass it to the first character of the String using the String.charAt() method.

Character.isDigit(myString.charAt(0));

// String.class here is the parameter type, that might not be the case with you
Method method = clazz.getMethod("methodName", String.class);
Object o = method.invoke(null, "whatever");

In case the method is private use getDeclaredMethod() instead of getMethod(). And call setAccessible(true) on the method object.

Here is the non-jQuery way of tapping into the resize event:

window.addEventListener('resize', function(event){
  // do stuff here
});

It works on all modern browsers. It does not throttle anything for you. Here is an example of it in action.

You can do the HTML parsing but it is not at all recommended instead ask the website owners to provide web services then you can parse that information.

zerkms told you the difference. If you like you can "convert" a string to an array of strings with length of 1.

If you want to send the string as a argument for example you can do like this:

var myString = "Test";

MethodThatRequiresStringArrayAsParameter( new[]{myString} );

I honestly can't see any other reason of doing the conversion than to satisty a method argument, but if it's another reason you will have to provide some information as to what you are trying to accomplish since there is probably a better solution.

For some reason, I was missing the settings.gradle file.

1. Create settings.gradle under your root directory, and inside it:

include ':app'

(assuming your app is indeed inside /app directory).

2. Hit File -> Sync Project with Gradle Files.

After that everything worked out for me.

Another built-in command that's long been installed in Windows by default dating back to 2003 is Certutil, which of course can be invoked from PowerShell, too.

CertUtil -hashfile file.foo MD5

(Caveat: MD5 should be in all caps for maximum robustness)

If you don't need to worry about scientific or other expressions of numbers and are only working with strings that could be numbers with or without a period:

Function

def is_float(s):
    result = False
    if s.count(".") == 1:
        if s.replace(".", "").isdigit():
            result = True
    return result

Lambda version

is_float = lambda x: x.replace('.','',1).isdigit() and "." in x

Example

if is_float(some_string):
    some_string = float(some_string)
elif some_string.isdigit():
    some_string = int(some_string)
else:
    print "Does not convert to int or float."

This way you aren't accidentally converting what should be an int, into a float.

To see a list of HTTP request headers, you can use :

console.log(JSON.stringify(req.headers));

to return a list in JSON format.

{
"host":"localhost:8081",
"connection":"keep-alive",
"cache-control":"max-age=0",
"accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"upgrade-insecure-requests":"1",
"user-agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36",
"accept-encoding":"gzip, deflate, sdch",
"accept-language":"en-US,en;q=0.8,et;q=0.6"
}

Apply does the job well, but is quite slow. Using sapply and vapply could be useful. dplyr's rowwise could also be useful Let's see an example of how to do row wise product of any data frame.

a = data.frame(t(iris[1:10,1:3]))
vapply(a, prod, 0)
sapply(a, prod)

Note that assigning to variable before using vapply/sapply/ apply is good practice as it reduces time a lot. Let's see microbenchmark results

a = data.frame(t(iris[1:10,1:3]))
b = iris[1:10,1:3]
microbenchmark::microbenchmark(
    apply(b, 1 , prod),
    vapply(a, prod, 0),
    sapply(a, prod) , 
    apply(iris[1:10,1:3], 1 , prod),
    vapply(data.frame(t(iris[1:10,1:3])), prod, 0),
    sapply(data.frame(t(iris[1:10,1:3])), prod) ,
    b %>%  rowwise() %>%
        summarise(p = prod(Sepal.Length,Sepal.Width,Petal.Length))
)

Have a careful look at how t() is being used

Get List of function_schema and function_name...

SELECT
    n.nspname AS function_schema,
    p.proname AS function_name
FROM
    pg_proc p
    LEFT JOIN pg_namespace n ON p.pronamespace = n.oid
WHERE
    n.nspname NOT IN ('pg_catalog', 'information_schema')
ORDER BY
    function_schema,
    function_name;

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

I recently got this error because the typo, I write 'canavas' instead of 'canvas', hope this could help someone who is searching for this.

What about the Activity.finish() method (quoting) :

Call this when your activity is done and should be closed.

url_for in Flask is used for creating a URL to prevent the overhead of having to change URLs throughout an application (including in templates). Without url_for, if there is a change in the root URL of your app then you have to change it in every page where the link is present.

Syntax: url_for('name of the function of the route','parameters (if required)')

It can be used as:

@app.route('/index')
@app.route('/')
def index():
    return 'you are in the index page'

Now if you have a link the index page:you can use this:

<a href={{ url_for('index') }}>Index</a>

You can do a lot o stuff with it, for example:

@app.route('/questions/<int:question_id>'):    #int has been used as a filter that only integer will be passed in the url otherwise it will give a 404 error
def find_question(question_id):  
    return ('you asked for question{0}'.format(question_id))

For the above we can use:

<a href = {{ url_for('find_question' ,question_id=1) }}>Question 1</a>

Like this you can simply pass the parameters!

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

The simplest way to initialize an array

Create array

$array = @()

Create your header

$line = "" | select name,age,phone

Fill the line

$line.name = "Leandro"
$line.age = "39"
$line.phone = "555-555555"

Add line to $array

$array += $line

Result

$array

name                                                     age                                                      phone
----                                                     ---                                                      -----
Leandro                                                  39                                                       555-555555

A modified python version of @danack's PHP generate script. It generates all files & folders that live inside of build/ to the parent directory, replacing all {{placeholder}} matches. You need to cd into build/ before running the script.

File structure

build/
-- (files/folders you want to generate)
-- build.py

sites-available/...
sites-enabled/...
nginx.conf
...

build.py

import os, re

# Configurations
target = os.path.join('.', '..')
variables = {
  'placeholder': 'your replacement here'
}


# Loop files
def loop(cb, subdir=''):
  dir = os.path.join('.', subdir);

  for name in os.listdir(dir):
    file = os.path.join(dir, name)
    newsubdir = os.path.join(subdir, name)

    if name == 'build.py': continue
    if os.path.isdir(file): loop(cb, newsubdir)
    else: cb(subdir, name)


# Update file
def replacer(subdir, name):
  dir  = os.path.join(target, subdir)
  file = os.path.join(dir, name)
  oldfile = os.path.join('.', subdir, name)

  with open(oldfile, "r") as fin:
    data = fin.read()

  for key, replacement in variables.iteritems():
    data = re.sub(r"{{\s*" + key + "\s*}}", replacement, data)

  if not os.path.exists(dir):
    os.makedirs(dir)

  with open(file, "w") as fout:
    fout.write(data)


# Start variable replacements.
loop(replacer)

Note that you can also create your own structures using a Map.Entry as the main type, using its basic implementation AbstractMap.SimpleEntry. For instance, if you wanted to have an ordered list of entries, you could write:

List<Map.Entry<String, Integer>> entries = new ArrayList<>();
entries.add(new AbstractMap.SimpleEntry<String, Integer>(myStringValue, myIntValue));

And so on. From there, you have a list of tuples. Very useful when you want ordered tuples and a basic Map is a no-go.

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

Suppose I have Hashmap with key datatype as KeyDataType and value datatype as ValueDataType

HashMap<KeyDataType,ValueDataType> list;

Add all items you needed to it. Now you can retrive all hashmap keys to a list by.

KeyDataType[] mKeys;
mKeys=list.keySet().toArray(new KeyDataType[list.size()]);

So, now you got your all keys in an array mkeys[]

you can now retrieve any value by calling

 list.get(mkeys[position]);

Here is a working example of how you could implement custom functions for your anchors.

http://jsfiddle.net/CH2NZ/43/

You can attach an id to your anchor:

<li><a id="alertMe" href="#">Action</a></li>

And then use jQuery's click event listener to listen for the click action and fire you function:

$('#alertMe').click(function(e) {
    alert('alerted');
    e.preventDefault();// prevent the default anchor functionality
});
