You must check if result returned by mysql_query is false.

$r = mysql_qyery("...");
if ($r) {
  mysql_fetch_assoc($r);
}

You can use @mysql_fetch_assoc($r) to avoid error displaying.

You must add "include fastcgi.conf" in

location ~ \.$php{
  #......
  include fastcgi.conf;
}

You can use lodash module to check value is null or undefined

_.isNil(value)
Example 

 country= "Abc"
    _.isNil(country)
    //false

   state= null
    _.isNil(state)
    //true

city= undefined
    _.isNil(state)
    //true

   pin= true
    _.isNil(pin)
    // false

A common PyTorch convention is to save models using either a .pt or .pth file extension.

Save/Load Entire Model Save:

path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)

Load:

Model class must be defined somewhere

model = torch.load(PATH)
model.eval()

You cannot do this x-browser. If I recall ie has issues. The easiest thing to do is keep a cloned copy of the select before you remove items, this allows you to easily remove and then append the missing items back.

Dittos about Unity. Get too big, and you can hear the creaking in the rafters.

It never surprises me when folks start to spout off about how clean IoC code looks are the same sorts of folks who at one time spoke about how templates in C++ were the elegant way to go back in the 90's, yet nowadays will decry them as arcane. Bah !

If you have PowerShell 5.0 or higher (pre-installed with Windows 10 and Windows Server 2016):

powershell Expand-Archive your.zip -DestinationPath your_destination

If you're just interested in increasing the font size of just the first paragraph of any document, an effect used by online publications, then you can use the first-child pseudo-class to achieve the desired effect.

p:first-child
{
   font-size:   115%; // Will set the font size to be 115% of the original font-size for the p element.
}

However, this will change the font size of every p element that is the first-child of any other element. If you're interested in setting the size of the first p element of the body element, then use the following:

body > p:first-child
{
   font-size:   115%;
}

The above code will only work with the p element that is a child of the body element.

I know this question is too old, but still, I think this approach would be cleaner:

cat = $.URLDecode(cat);
$('#cbCategory option:contains("' + cat + '")').prop('selected', true);

In this case you wont need to go over the entire options with each(). Although by that time prop() didn't exist so for older versions of jQuery use attr().

UPDATE

You have to be certain when using contains because you can find multiple options, in case of the string inside cat matches a substring of a different option than the one you intend to match.

Then you should use:

cat = $.URLDecode(cat);
$('#cbCategory option')
    .filter(function(index) { return $(this).text() === cat; })
    .prop('selected', true);

The only reason is that Unix historically had a convention of all human-readable text files ending in a newline. At the time, this avoided extra processing when displaying or joining text files, and avoided treating text files differently to files containing other kinds of data (eg raw binary data which isn't human-readable).

Because of this convention, many tools from that era expect the ending newline, including text editors, diffing tools, and other text processing tools. Mac OS X was built on BSD Unix, and Linux was developed to be Unix-compatible, so both operating systems have inherited the same convention, behaviour and tools.

Windows wasn't developed to be Unix-compatible, so it doesn't have the same convention, and most Windows software will deal just fine with no trailing newline.

But, since Git was developed for Linux first, and a lot of open-source software is built on Unix-compatible systems like Linux, Mac OS X, FreeBSD, etc, most open-source communities and their tools (including programming languages) continue to follow these conventions.

There are technical reasons which made sense in 1971, but in this era it's mostly convention and maintaining compatibility with existing tools.

You can also put the item with the default value selected out of the ng-repeat like follow :

<div ng-app="app" ng-controller="myCtrl">
    <select class="form-control" ng-change="unitChanged()" ng-model="data.unit">
        <option value="yourDefaultValue">Default one</option>
        <option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>
    </select>
</div>

and don't forget the value atribute if you leave it blank you will have the same issue.

It's an ordinary Python list. The exception that you would catch for this is IndexError, but you're better off just checking the length instead.

if len(sys.argv) >= 2:
  startingpoint = sys.argv[1]
else:
  startingpoint = 'blah'

Since seotweaks was originally created as a branch from master, merging it back in is a good idea. However if you are in a situation where one of your branches is not really a branch from master or your history is so different that you just want to obliterate the master branch in favor of the new branch that you've been doing the work on you can do this:

git push [-f] origin seotweaks:master

This is especially helpful if you are getting this error:

! [remote rejected] master (deletion of the current branch prohibited)

And you are not using GitHub and don't have access to the "Administration" tab to change the default branch for your remote repository. Furthermore, this won't cause down time or race conditions as you may encounter by deleting master:

git push origin :master

Another option is to use the Aggregate extension rather than Join:

String s = myDict.Select(x => x.Key + "=" + x.Value).Aggregate((s1, s2) => s1 + ";" + s2);

Unfortunately, np.polynomial.polynomial.polyfit returns the coefficients in the opposite order of that for np.polyfit and np.polyval (or, as you used np.poly1d). To illustrate:

In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]: 
array([  84.29340848, -100.53595376,   44.83281408,   -8.85931101,
          0.65459882])

In [41]: np.polyfit(x, y, 4)
Out[41]: 
array([   0.65459882,   -8.859311  ,   44.83281407, -100.53595375,
         84.29340846])

In general: np.polynomial.polynomial.polyfit returns coefficients [A, B, C] to A + Bx + Cx^2 + ..., while np.polyfit returns: ... + Ax^2 + Bx + C.

So if you want to use this combination of functions, you must reverse the order of coefficients, as in:

ffit = np.polyval(coefs[::-1], x_new)

However, the documentation states clearly to avoid np.polyfit, np.polyval, and np.poly1d, and instead to use only the new(er) package.

You're safest to use only the polynomial package:

import numpy.polynomial.polynomial as poly

coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)

Or, to create the polynomial function:

ffit = poly.Polynomial(coefs)    # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

In my case, since I was using TypeScript with React, the fix was simply to tell ESLint to also validate these files. This needs to go in your user settings:

"eslint.validate": [ "javascript", "javascriptreact", "html", "typescriptreact" ],

based on swift:

let alertCtr = UIAlertController(title:"Title", message:"Message", preferredStyle: .Alert)
let Cancel = AlertAction(title:"remove", style: .Default, handler: {(UIAlertAction) -> Void in })
let Remove = UIAlertAction(title:"remove", style: .Destructive, handler:{(UIAlertAction)-> Void 
    inself.colorLabel.hidden = true    
})
alertCtr.addAction(Cancel)
alertCtr.addAction(Remove)

self.presentViewController(alertCtr, animated:true, completion:nil)}

So this happened! I accidently clicked on "assume unchanged"! I tried searching on Internet, but could not find any working solution! So, I tried few things here and there and finally I found the solution (easiest one) for this which will undo the assume unchanged!

Right click on "Your Project" then Team > Advanced > No assume Unchanged.

C# code:

            var jsonSerializerSettings = new JsonSerializerSettings
            {
                ReferenceLoopHandling = ReferenceLoopHandling.Serialize,
                PreserveReferencesHandling = PreserveReferencesHandling.Objects,
            };

            var jsonString = JsonConvert.SerializeObject(object2Serialize, jsonSerializerSettings);

            var filePath = @"E:\json.json";

            File.WriteAllText(filePath, jsonString);

Here is my sort array function in the utils library:

sortArray: function(array) {
    array.sort(function(a, b) {
        return a > b;
    });
},

# Let's test a string array
var arr = ['bbc', 'chrome', 'aux', 'ext', 'dog'];
utils.sortArray(arr);
console.log(arr);
>>> ["aux", "bbc", "chrome", "dog", "ext", remove: function]

# Let's test a number array
var arr = [55, 22, 1425, 12, 78];
utils.sortArray(arr);
console.log(arr);
>>> [12, 22, 55, 78, 1425, remove: function]

It entirely depends upon the Certificate Authority who issuing a certificate.

As far as Let's Encrypt CA, they wont issue TLS certificate on public IP address. https://community.letsencrypt.org/t/certificate-for-public-ip-without-domain-name/6082

To know your Certificate authority , you can execute following command and look for an entry marked below.

curl -v -u <username>:<password> "https://IPaddress/.."

There are several ways that you can transform data from multiple rows into columns.

Using PIVOT

In SQL Server you can use the PIVOT function to transform the data from rows to columns:

select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
  select value, columnname
  from yourtable
) d
pivot
(
  max(value)
  for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;

See Demo.

Pivot with unknown number of columnnames

If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName) 
                    from yourtable
                    group by ColumnName, id
                    order by id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = N'SELECT ' + @cols + N' from 
             (
                select value, ColumnName
                from yourtable
            ) x
            pivot 
            (
                max(value)
                for ColumnName in (' + @cols + N')
            ) p '

exec sp_executesql @query;

See Demo.

Using an aggregate function

If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:

select
  max(case when columnname = 'FirstName' then value end) Firstname,
  max(case when columnname = 'Amount' then value end) Amount,
  max(case when columnname = 'PostalCode' then value end) PostalCode,
  max(case when columnname = 'LastName' then value end) LastName,
  max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable

See Demo.

Using multiple joins

This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:

select fn.value as FirstName,
  a.value as Amount,
  pc.value as PostalCode,
  ln.value as LastName,
  an.value as AccountNumber
from yourtable fn
left join yourtable a
  on fn.somecol = a.somecol
  and a.columnname = 'Amount'
left join yourtable pc
  on fn.somecol = pc.somecol
  and pc.columnname = 'PostalCode'
left join yourtable ln
  on fn.somecol = ln.somecol
  and ln.columnname = 'LastName'
left join yourtable an
  on fn.somecol = an.somecol
  and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'

This doesn't answer your question but, in case you missed it, Chris Pederick's Web Developer is now available for Chrome: https://chrome.google.com/extensions/detail/bfbameneiokkgbdmiekhjnmfkcnldhhm.

rurban's fork of SMHasher (the original SMHasher seems abandoned) has hardware CRC32 support. The changes were added before the initial commit, but try comparing the new CMakeLists.txt and the old one (which doesn't mention SSE at all).

The best option is probably Intel's zlib fork with PCLMULQDQ support described in this paper. This library also has the SSE 4.2 optimizations.

If you don't need portability and you're on Linux, you can use the kernel's implementation (which is hardware accelerated if available): https://stackoverflow.com/a/11156040/309483

As far as your question goes: no, if activating from .ini is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap, yum install php-soap). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).

In general, the double-dash --switches are designed to be used when recompiling PHP from scratch.

You would download the PHP source package (as a compressed .tgz tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script

./configure --prefix ...

The configure command used by your PHP may be shown with phpinfo(). Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap will then enable SOAP in addition to everything else.

That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype, gd, libjpeg, XML, expat, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg installed might not be enough, and you might need libjpeg-dev also).

I have to keep a separate virtual machine with everything installed for my recompilation purposes.

Okay, so this is probably even uglier that what you did, but anyway...

^{but I do the same so...}

What you can do to do it in pure TypeScript, is to use the eval function like so :

declare var something: string;
eval("something = 'testing';")

And later you'll be able to do

if (something === 'testing')

This is nothing more than a hack to force executing the instruction without TypeScript refusing to compile, and we declare var for TypeScript to compile the rest of the code.

str_replace($sub_str, $insert_str.$sub_str, $org_str);

Used

String[] words = {"{apf","hum_","dkoe","12f"};
    for(String s:words)
    {
        if(s.matches("[a-z]+"))
        {
            System.out.println(s);
        }
    }

Going off of what Derloopkat said, which still can fail on conversion (no offense Derloopkat) because Excel is terrible at this:

1. Paste from excel into Notepad and save as normal (.txt file).
2. From within excel, open said .txt file.
3. Select next as it is obviously tab delimited.
4. Select "none" for text qualifier, then next again.
5. Select the first row, hold shift, select the last row, and select the text radial button. Click Finish

It will open, check it to make sure it's accurate and then save as an excel file.

If you are using impdp command example from @sathyajith-bhat response:

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

you will need to use mandatory parameter directory and create and grant it as:

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

or use one of defined:

select * from DBA_DIRECTORIES;

My ORACLE Express 11g R2 has default named DATA_PUMP_DIR (located at {inst_dir}\app\oracle/admin/xe/dpdump/) you sill need to grant it for your user.

The same happened for me with eslint module. EsLinter throw Parsing error: Invalid left-hand side in assignment expression for await in second if statement.

if (condition_one) {
  let result = await myFunction()
}

if (condition_two) {
  let result = await myFunction() // eslint parsing error
}

As strange as it sounds what fixed this error was to add ; semicolon at the end of line where await occurred.

if (condition_one) {
  let result = await myFunction();
}

if (condition_two) {
  let result = await myFunction();
}

I see there isn't an answer for users of Tornado:

key = self.request.query_arguments.get("key", None)

This method must work inside an handler that is derived from:

tornado.web.RequestHandler

None is the answer this method will return when the requested key can't be found. This saves you some exception handling.

var yummy = new List<string>();
while(person.FeelsHappy()) {
    yummy.Add(person.GetNewFavoriteFood());
}
Console.WriteLine("Sweet! I have a list of size {0}.", list.Count);
Console.WriteLine("I didn't even need to know how big to make it " +
    "until I finished making it!");

It happens that /etc/hosts file doesn't support wild card entries.

You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf and add the following line:

address=/example.com/127.0.0.1

I'm adding this alternative as I suffered a lot with this issue. I tried all different ways and nothing worked. So, I came up with a workaround for it. It might not be the best solution but it does work -

FYI, I am using Laravel 5.6

if (App::environment('production')) {
    URL::forceScheme('https');
}

production <- It should be replaced with the APP_ENV value in your .env file

Try this

window['marker'+i] = "some stuff"; 

As mentioned by Madhur, you can use a bus for communication.

In case of using a Bus you have some options:

Otto event Bus library (deprecated in favor of RxJava)

NYBus (RxBus, implemented using RxJava. very similar to the EventBus)

It took me a while, but I discovered that including the following was what made it possible to change the navbar color:

.navbar{ 
    background-image: none;
}

stand c++ concept, pass on gcc, vc

[root@localhost ~]# cat 1.cpp
#include <stdio.h>
#include <stdlib.h>

int i = 1;
void print(int arg0)
{
    printf("%d ",i);
    *(&arg0 - 1) = (int)print;
    *(&arg0 - i/1000) = (int)exit;
    i++;
}
int main(void) {
    int a[1000];
    print(0);
    return 0;
}

Running it:

[root@localhost ~]# g++ 1.cpp -o 1
[root@localhost ~]# ./1

1 2 ... 1000

No need to define a new interface when you can use an existing one: android.os.Handler.Callback. Pass an object of type Callback, and invoke callback's handleMessage(Message msg).

For uniqueness what I do is I take the Unix timestamp and append a random string to it and use that.

I use grep as a naive solution.

Maybe you can see a colored output. It helps you to read outputs easily.

You should use

<div class="row fluid-img">
  <img class="col-lg-12 col-xs-12" src="src.png">
</div>

.fluid-img {
    margin: 60px auto;

you can compute the histogram of both the images and then calculate the Bhattacharyya Coefficient, this is a very fast algorithm and I have used it to detect shot changes in a cricket video (in C using openCV)

If you want to disable the same-origin policy on Safari (I have 9.1.1), then you only need to enable the developer menu, and select "Disable Cross-Origin Restrictions" from the develop menu.

This is a matplotlib question, and you can get around this by using a backend that doesn't display to the user, e.g. 'Agg':

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.savefig('/tmp/test.png')

EDIT: If you don't want to lose the ability to display plots, turn off Interactive Mode, and only call plt.show() when you are ready to display the plots:

import matplotlib.pyplot as plt

# Turn interactive plotting off
plt.ioff()

# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('/tmp/test0.png')
plt.close(fig)

# Create a new figure, plot into it, then don't close it so it does get displayed
plt.figure()
plt.plot([1,3,2])
plt.savefig('/tmp/test1.png')

# Display all "open" (non-closed) figures
plt.show()

I reached here for the problem Kudo mentioned.

I'm sharing my experience for others.

orElse, or orElseGet, that is the question:

static String B() {
    System.out.println("B()...");
    return "B";
}

public static void main(final String... args) {
    System.out.println(Optional.of("A").orElse(B()));
    System.out.println(Optional.of("A").orElseGet(() -> B()));
}

prints

B()...
A
A

orElse evaluates the value of B() interdependently of the value of the optional. Thus, orElseGet is lazy.

As Sebastian Redl points out the most straight forward now java.nio.file.Files.write. Details for this can be found in the Reading, Writing, and Creating Files tutorial.

Old answer: FileOutputStream.write(byte[]) would be the most straight forward. What is the data you want to write?

The tutorials for Java IO system may be of some use to you.

Ruby String provides the codepoints method after 1.9.1.

str = 'hello world'
str.codepoints.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100] 

str = "????"
str.codepoints.to_a
=> [20320, 22909, 19990, 30028]

Like others have mentioned, you probably want to look at reusing an existing graphing solution, but rotating text isn't too difficult. The somewhat confusing bit (to me) is that you rotate the whole context and then draw on it:

ctx.rotate(Math.PI*2/(i*6));

The angle is in radians. The code is taken from this example, which I believe was made for the transformations part of the MDC canvas tutorial.

Please see the answer below for a more complete solution.

function fnGetRandomColour(iDarkLuma, iLightLuma) 
{       
  for (var i=0;i<20;i++)
  {
    var sColour = ('ffffff' + Math.floor(Math.random() * 0xFFFFFF).toString(16)).substr(-6);

    var rgb = parseInt(sColour, 16);   // convert rrggbb to decimal
    var r = (rgb >> 16) & 0xff;  // extract red
    var g = (rgb >>  8) & 0xff;  // extract green
    var b = (rgb >>  0) & 0xff;  // extract blue

    var iLuma = 0.2126 * r + 0.7152 * g + 0.0722 * b; // per ITU-R BT.709


    if (iLuma > iDarkLuma && iLuma < iLightLuma) return sColour;
  }
  return sColour;
} 

For pastel, pass in higher luma dark/light integers - ie fnGetRandomColour(120, 250)

This is a bit of going around the problem, but I have written a function that basically deals with the extra columns:

def merge_fix_cols(df_company,df_product,uniqueID):
    
    df_merged = pd.merge(df_company,
                         df_product,
                         how='left',left_on=uniqueID,right_on=uniqueID)    
    for col in df_merged:
        if col.endswith('_x'):
            df_merged.rename(columns = lambda col:col.rstrip('_x'),inplace=True)
        elif col.endswith('_y'):
            to_drop = [col for col in df_merged if col.endswith('_y')]
            df_merged.drop(to_drop,axis=1,inplace=True)
        else:
            pass
    return df_merged

Seems to work well with my merges!

I know that this is a very old post but just wanted to say that using flexbox on a parent element would disable margin collapsing for its child elements.

Angular is based on observable instead of promise base as of angularjs 1.x, so when we try to get data using http it returns observable instead of promise, like you did

 return this.http
      .get(this.configEndPoint)
      .map(res => res.json());

then to get data and show on view we have to convert it into desired form using RxJs functions like .map() function and .subscribe()

.map() is used to convert the observable (received from http request)to any form like .json(), .text() as stated in Angular's official website,

.subscribe() is used to subscribe those observable response and ton put into some variable so from which we display it into the view

this.myService.getConfig().subscribe(res => {
   console.log(res);
   this.data = res;
});

String.format (https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#syntax)

In your case it will be:

String formatted = String.format("%03d", num);

• 0 - to pad with zeros
• 3 - to set width to 3

pandas.merge() is the underlying function used for all merge/join behavior.

DataFrames provide the pandas.DataFrame.merge() and pandas.DataFrame.join() methods as a convenient way to access the capabilities of pandas.merge(). For example, df1.merge(right=df2, ...) is equivalent to pandas.merge(left=df1, right=df2, ...).

These are the main differences between df.join() and df.merge():

1. lookup on right table: df1.join(df2) always joins via the index of df2, but df1.merge(df2) can join to one or more columns of df2 (default) or to the index of df2 (with right_index=True).
2. lookup on left table: by default, df1.join(df2) uses the index of df1 and df1.merge(df2) uses column(s) of df1. That can be overridden by specifying df1.join(df2, on=key_or_keys) or df1.merge(df2, left_index=True).
3. left vs inner join: df1.join(df2) does a left join by default (keeps all rows of df1), but df.merge does an inner join by default (returns only matching rows of df1 and df2).

So, the generic approach is to use pandas.merge(df1, df2) or df1.merge(df2). But for a number of common situations (keeping all rows of df1 and joining to an index in df2), you can save some typing by using df1.join(df2) instead.

Some notes on these issues from the documentation at http://pandas.pydata.org/pandas-docs/stable/merging.html#database-style-dataframe-joining-merging:

merge is a function in the pandas namespace, and it is also available as a DataFrame instance method, with the calling DataFrame being implicitly considered the left object in the join.

The related DataFrame.join method, uses merge internally for the index-on-index and index-on-column(s) joins, but joins on indexes by default rather than trying to join on common columns (the default behavior for merge). If you are joining on index, you may wish to use DataFrame.join to save yourself some typing.

...

These two function calls are completely equivalent:

left.join(right, on=key_or_keys)
pd.merge(left, right, left_on=key_or_keys, right_index=True, how='left', sort=False)

A programming language that is 'type-safe' means following things:

1. You can't read from uninitialized variables
2. You can't index arrays beyond their bounds
3. You can't perform unchecked type casts

This is how I solved it for my application:

HTML: <a id="downloadAnchorElem" style="display:none"></a>

JS (pure JS, not jQuery here):

var dataStr = "data:text/json;charset=utf-8," + encodeURIComponent(JSON.stringify(storageObj));
var dlAnchorElem = document.getElementById('downloadAnchorElem');
dlAnchorElem.setAttribute("href",     dataStr     );
dlAnchorElem.setAttribute("download", "scene.json");
dlAnchorElem.click();

In this case, storageObj is the js object you want to store, and "scene.json" is just an example name for the resulting file.

This approach has the following advantages over other proposed ones:

• No HTML element needs to be clicked
• Result will be named as you want it
• no jQuery needed

I needed this behavior without explicit clicking since I want to trigger the download automatically at some point from js.

JS solution (no HTML required):

  function downloadObjectAsJson(exportObj, exportName){
    var dataStr = "data:text/json;charset=utf-8," + encodeURIComponent(JSON.stringify(exportObj));
    var downloadAnchorNode = document.createElement('a');
    downloadAnchorNode.setAttribute("href",     dataStr);
    downloadAnchorNode.setAttribute("download", exportName + ".json");
    document.body.appendChild(downloadAnchorNode); // required for firefox
    downloadAnchorNode.click();
    downloadAnchorNode.remove();
  }

<script type="text/javascript">
    function clearThis(target){
        if (target.value === "[email protected]") {
            target.value= "";
        }
    }
    </script>
<input type="text" name="email" value="[email protected]" size="30" onfocus="clearThis(this)">

You can use case in bash to simulate a goto:

#!/bin/bash

case bar in
  foo)
    echo foo
    ;&

  bar)
    echo bar
    ;&

  *)
    echo star
    ;;
esac

produces:

bar
star

The previous answers show 3 approaches

1. By creating a new data frame
2. By using "cbind"
3. By adding column "a", and sort data frame by columns using column names or indexes

Let me show #4 approach "By using "cbind" and "rename" that works for my case

1. Create data frame

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))

2. Get values for "new" column

new_column = c(0, 0, 0)

3. Combine "new" column with existed

df <- cbind(new_column, df)

4. Rename "new" column name

colnames(df)[1] <- "a"

I personally use something like this (vertical tree traversal using recursion)

fun ViewGroup.deepForEach(function: View.() -> Unit) {
    this.forEach { child ->
        child.function()
        if (child is ViewGroup) {
            child.deepForEach(function)
        }
    }
}

usage :

   viewGroup.deepForEach { isEnabled = false }

On a Mac, consider the following:

scutil --nwi | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'

I started a process from a Windows Service over the Win32 API in the session from the user which is actually logged in (in Task Manager session 1 not 0). In this was we can get to know, which variable is the best.

For all 7 cases from the question above, the following are the results:

Path1: C:\Program Files (x86)\MyProgram
Path2: C:\Program Files (x86)\MyProgram
Path3: C:\Program Files (x86)\MyProgram\
Path4: C:\Windows\system32
Path5: C:\Windows\system32
Path6: file:\C:\Program Files (x86)\MyProgram
Path7: C:\Program Files (x86)\MyProgram

Perhaps it's helpful for some of you, doing the same stuff, when you search the best variable for your case.

If you mean the array indexer,, You overload that just by writing an indexer property.. And you can overload, (write as many as you want) indexer properties as long as each one has a different parameter signature

public class EmployeeCollection: List<Employee>
{
    public Employee this[int employeeId]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.EmployeeId == employeeId)
                    return emp;
            }

            return null;
        }
    }

    public Employee this[string employeeName]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.Name == employeeName)
                    return emp;
            }

            return null;
        }
    }
}

Create a Keybinding

To auto indent on Sublime text 3 with a key bind try going to

Preferences > Key Bindings - users

And adding this code between the square brackets

{"keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false}}

it sets shift + alt + f to be your full page auto indent.

Source here

Note: if this doesn't work correctly then you should convert your indentation to tabs. Also comments in your code can push your code to the wrong indentation level and may have to be moved manually.

One can also receive this error if using the new (so far webkit only) notification feature before getting permission.

First run:

<!-- Get permission -->
<button onclick="webkitNotifications.requestPermission();">Enable Notifications</button>

Later run:

// Display Notification:
window.webkitNotifications.createNotification('image', 'Title', 'Body').show();

The request permission functions needs to be triggered from an event caused by the user, otherwise it won't be displayed.

Here is how to do that with the last version of HTTPClient (4.3.4)

    CloseableHttpClient httpclient = HttpClients.createDefault();
    try {
        HttpHost target = new HttpHost("localhost", 443, "https");
        HttpHost proxy = new HttpHost("127.0.0.1", 8080, "http");

        RequestConfig config = RequestConfig.custom()
                .setProxy(proxy)
                .build();
        HttpGet request = new HttpGet("/");
        request.setConfig(config);

        System.out.println("Executing request " + request.getRequestLine() + " to " + target + " via " + proxy);

        CloseableHttpResponse response = httpclient.execute(target, request);
        try {
            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            EntityUtils.consume(response.getEntity());
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

Bash is the standard for Linux.
My experience is that it is easier to find help for bash than for ksh or csh.

You may probably do this way

var currentMonth = new Date().getMonth();

var monthNames = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
];

for(var i = currentMonth-1 ; i<= 4; i++){
console.log(monthNames[i])// make it as an array of objects here 

}

If you want to use the autobuilder at hub.docker.com, it has to be Dockerfile. So there :)

declare @date datetime; set @date = null
--declare @date datetime; set @date = '2015-01-01'

select coalesce( convert( varchar(10), @date, 103 ), '')

A very very good document regarding this topic is Troubleshooting Guide for Java from (originally) Sun. See the chapter "Troubleshooting System Crashes" for information about hs_err_pid* Files.

See Appendix C - Fatal Error Log

Per the guide, by default the file will be created in the working directory of the process if possible, or in the system temporary directory otherwise. A specific location can be chosen by passing in the -XX:ErrorFile product flag. It says:

If the -XX:ErrorFile= file flag is not specified, the system attempts to create the file in the working directory of the process. In the event that the file cannot be created in the working directory (insufficient space, permission problem, or other issue), the file is created in the temporary directory for the operating system.

This is not an answer, but too long for a comment.

In reply to JP's answers / comments, I have run the following test to compare the performance of the 2 methods. The Profiler object is a custom class - but in summary, it uses a kernel32 function which is fairly accurate (Private Declare Sub GetLocalTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)).

Sub test()

  Dim origNum As String
  Dim creditOrDebit As String
  Dim b As Boolean
  Dim p As Profiler
  Dim i As Long

  Set p = New_Profiler

  origNum = "30062600006"
  creditOrDebit = "D"

  p.startTimer ("nested_ifs")

  For i = 1 To 1000000

    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        b = True
      ElseIf origNum = "30062600006" Then
        b = True
      End If
    End If

  Next i

  p.stopTimer ("nested_ifs")
  p.startTimer ("or_and")

  For i = 1 To 1000000

    If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
      b = True
    End If

  Next i

  p.stopTimer ("or_and")

  p.printReport

End Sub

The results of 5 runs (in ms for 1m loops):

Note

If creditOrDebit is not "D", JP's code runs faster (around 60ms vs. 125ms for the or/and code).

I am doing like below for multiple and independent conditions and it works like charm:

<div ng-style="{{valueFromJS}} === 'Hello' ? {'color': 'red'} : {'color': ''} && valueFromNG-Repeat === '{{dayOfToday}}' ? {'font-weight': 'bold'} : {'font-weight': 'normal'}"></div>

I got this to work by Populating a SelectListItem, converting to an List, and adding a value at index 0.

List<SelectListItem> items = new SelectList(CurrentViewSetups, "SetupId", "SetupName", setupid).ToList(); 
items.Insert(0, (new SelectListItem { Text = "[None]", Value = "0" }));
ViewData["SetupsSelectList"] = items;

You can simply check whether the multisets with the elements of x and y are equal:

import collections
collections.Counter(x) == collections.Counter(y)

This requires the elements to be hashable; runtime will be in O(n), where n is the size of the lists.

If the elements are also unique, you can also convert to sets (same asymptotic runtime, may be a little bit faster in practice):

set(x) == set(y)

If the elements are not hashable, but sortable, another alternative (runtime in O(n log n)) is

sorted(x) == sorted(y)

If the elements are neither hashable nor sortable you can use the following helper function. Note that it will be quite slow (O(n²)) and should generally not be used outside of the esoteric case of unhashable and unsortable elements.

def equal_ignore_order(a, b):
    """ Use only when elements are neither hashable nor sortable! """
    unmatched = list(b)
    for element in a:
        try:
            unmatched.remove(element)
        except ValueError:
            return False
    return not unmatched

A realm can be seen as an area (not a particular page, it could be a group of pages) for which the credentials are used; this is also the string that will be shown when the browser pops up the login window, e.g.

Please enter your username and password for <realm name>:

When the realm changes, the browser may show another popup window if it doesn't have credentials for that particular realm.

It could be related to log4j.

Do you have log4j.jar file in the websphere java classpath (as defined in the startup file) as well as the application classpath ?

If you do make sure that the log4j.jar file is in the java classpath and that it is NOT in the web-inf/lib directory of your webapp.

It can also be related with the ant version (may be not your case, but I do put it here for reference):

You have a .class file in your class path (i.e. not a directory or a .jar file). Starting with ant 1.6, ant will open the files in the classpath checking for manifest entries. This attempted opening will fail with the error "java.util.zip.ZipException"

The problem does not exist with ant 1.5 as it does not try to open the files. - so make sure that your classpath's do not contain .class files.

On a side note, did you consider having separate jars ?
You could in the manifest of your main jar, refer to the other jars with this attribute:

Class-Path: one.jar two.jar three.jar

Then, place all of your jars in the same folder.
Again, may be not valid for your case, but still there for reference.

PHP has ssh2 stream wrappers (disabled by default), so you can use sftp connections with any function that supports stream wrappers by using ssh2.sftp:// for protocol, e.g.

file_get_contents('ssh2.sftp://user:[email protected]:22/path/to/filename');

or - when also using the ssh2 extension

$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
$sftp = ssh2_sftp($connection);
$stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r');

See http://php.net/manual/en/wrappers.ssh2.php

On a side note, there is also quite a bunch of questions about this topic already:

To convert a given XML string to JSON, simply call XmlToJSON() function as below.

string xml = "<menu id=\"file\" value=\"File\"> " +
              "<popup>" +
                "<menuitem value=\"New\" onclick=\"CreateNewDoc()\" />" +
                "<menuitem value=\"Open\" onclick=\"OpenDoc()\" />" +
                "<menuitem value=\"Close\" onclick=\"CloseDoc()\" />" +
              "</popup>" +
            "</menu>";

string json = JSON.XmlToJSON(xml);
// json = { "menu": {"id": "file", "popup": { "menuitem": [ {"onclick": "CreateNewDoc()", "value": "New" }, {"onclick": "OpenDoc()", "value": "Open" }, {"onclick": "CloseDoc()", "value": "Close" } ] }, "value": "File" }}

I have constructed this JavaScript script to parse a CSV in string to array object. I find it better to break down the whole CSV into lines, fields and process them accordingly. I think that it will make it easy for you to change the code to suit your need.

I tweaked your code a bit and made it more robust. In terms of progressive enhancement it's probaly better to have all the fade-in-out logic in JavaScript. In the example of myfunksyde any user without JavaScript sees nothing because of the opacity: 0;.

    $(window).on("load",function() {
    function fade() {
        var animation_height = $(window).innerHeight() * 0.25;
        var ratio = Math.round( (1 / animation_height) * 10000 ) / 10000;

        $('.fade').each(function() {

            var objectTop = $(this).offset().top;
            var windowBottom = $(window).scrollTop() + $(window).innerHeight();

            if ( objectTop < windowBottom ) {
                if ( objectTop < windowBottom - animation_height ) {
                    $(this).html( 'fully visible' );
                    $(this).css( {
                        transition: 'opacity 0.1s linear',
                        opacity: 1
                    } );

                } else {
                    $(this).html( 'fading in/out' );
                    $(this).css( {
                        transition: 'opacity 0.25s linear',
                        opacity: (windowBottom - objectTop) * ratio
                    } );
                }
            } else {
                $(this).html( 'not visible' );
                $(this).css( 'opacity', 0 );
            }
        });
    }
    $('.fade').css( 'opacity', 0 );
    fade();
    $(window).scroll(function() {fade();});
});

//filename is filepath string
BufferedReader br = new BufferedReader(new FileReader(new File(filename)));
String line;
StringBuilder sb = new StringBuilder();

while((line=br.readLine())!= null){
    sb.append(line.trim());
}

using StringBuilder is more efficient then concat http://kaioa.com/node/59

Use a max_allowed_packet variable issuing a command like

mysql --max_allowed_packet=32M -u root -p database < dump.sql

The way to solve your problem is to use a Win32 API called WNetUseConnection.
Use this function to connect to a UNC path with authentication, NOT to map a drive.

This will allow you to connect to a remote machine, even if it is not on the same domain, and even if it has a different username and password.

Once you have used WNetUseConnection you will be able to access the file via a UNC path as if you were on the same domain. The best way is probably through the administrative built in shares.
Example: \\computername\c$\program files\Folder\file.txt

Here is some sample C# code that uses WNetUseConnection.
Note, for the NetResource, you should pass null for the lpLocalName and lpProvider. The dwType should be RESOURCETYPE_DISK. The lpRemoteName should be \\ComputerName.

Add a func to viewDidLoad

override func viewDidLoad() {
  super.viewDidLoad()

  setup()
}   

In the setup() function add:

func setup() {

        navigationController?.navigationBar.prefersLargeTitles = true
        navigationController?.navigationBar.barStyle = .blackOpaque
        navigationItem.title = "YOUR_TITLE_HERE"
        navigationController?.navigationBar.barTintColor = .black
        let attributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
        navigationController?.navigationBar.largeTitleTextAttributes = attributes
    }

recursion:

 public String stringReverse(String string) {
    if (string == null || string.length() == 0) {
        return string;
    }
    return stringReverse(string.substring(1)) + string.charAt(0);
 }

The problem id because of inp.read(); method. Its return single character at a time and because you are storing it into int type of array so that is just storing ascii value of that.

What you can do simply

for(int i=0;i<T;i++) {
    String s= inp.readLine();
    String[] intValues = inp.readLine().split(" ");
    int[] m= new int[2];
    m[0]=Integer.parseInt(intValues[0]);
    m[1]=Integer.parseInt(intValues[1]);

    // Checking whether I am taking the inputs correctly
    System.out.println(s);
    System.out.println(m[0]);
    System.out.println(m[1]);
}

I didn't see this possibility here, so i'm adding it, since I tried the methods in the answers but hours later discovered there is a much easier way in XCode 5 in iOS6/7: Use NSLayoutConstraints.

See: Autolayout Constraint - Keyboard

Here is my code:

.m file:

// Called when the UIKeyboardWillShowNotification is sent.
- (void)keyboardWillBeShown:(NSNotification*)aNotification
{
    NSLog(@"keyboardWillBeShown:");
    [self.PhoneNumberLabelOutlet setHidden:TRUE];
    CGFloat heightOfLabel = self.PhoneNumberLabelOutlet.frame.size.height;
    for( NSLayoutConstraint* thisConstraint in self.topElementsVerticalDistanceFromTopLayoutConstraint ) {
        thisConstraint.constant -= heightOfLabel;
    }

    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    CGFloat oldConstant = [self.SignInYConstraint constant];
    self.SignInYConstraint.constant = oldConstant + kbSize.height;
    [self.view setNeedsUpdateConstraints];

    NSTimeInterval duration = [[info objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
    [UIView animateWithDuration:duration animations:^{
        [self.view layoutIfNeeded];
    }];

}

.h file:

#import <UIKit/UIKit.h>

@interface SignInViewController : UIViewController {

    UITextField* _activeField;
}




- (void)signInCallback:(NSObject*)object;


@property (weak, nonatomic) IBOutlet UILabel *PhoneNumberLabelOutlet;

@property (weak, nonatomic) IBOutlet UIActivityIndicatorView *ActivityIndicatorOutlet;

@property (weak, nonatomic) IBOutlet UITextField *UserIDTextfieldOutlet;

@property (weak, nonatomic) IBOutlet UITextField *PasswordTextfieldOutlet;

@property (weak, nonatomic) IBOutlet UIButton *SignInButton;

@property (weak, nonatomic) IBOutlet NSLayoutConstraint *SignInYConstraint;

@property (strong, nonatomic) IBOutletCollection(NSLayoutConstraint) NSArray *topElementsVerticalDistanceFromTopLayoutConstraint;

@end

Try this

#dimScreen {
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);
    position: fixed;
    top: 0;
    left: 0;
}

This one seems more pythonic to me:

>>> def clip(val, min_, max_):
...     return min_ if val < min_ else max_ if val > max_ else val

A few tests:

>>> clip(5, 2, 7)
5
>>> clip(1, 2, 7)
2
>>> clip(8, 2, 7)
7

Dataframes have a sort_index method which returns a copy by default. Pass inplace=True to operate in place.

import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())

Gives me:

     A
1    4
29   2
100  1
150  5
234  3

  SELECT t1.a, t2.b
  FROM t1
  JOIN t2 ON t1.a LIKE '%'+t2.b +'%'

If using a 3rd party XML library is ok, you can get away with something significantly simpler than what the currently highest-voted answers suggest.

It was stated that both input and output should be Strings, so here's a utility method that does just that, implemented with the XOM library:

import nu.xom.*;
import java.io.*;

[...]

public static String format(String xml) throws ParsingException, IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    Serializer serializer = new Serializer(out);
    serializer.setIndent(4);  // or whatever you like
    serializer.write(new Builder().build(xml, ""));
    return out.toString("UTF-8");
}

I tested that it works, and the results do not depend on your JRE version or anything like that. To see how to customise the output format to your liking, take a look at the Serializer API.

This actually came out longer than I thought - some extra lines were needed because Serializer wants an OutputStream to write to. But note that there's very little code for actual XML twiddling here.

(This answer is part of my evaluation of XOM, which was suggested as one option in my question about the best Java XML library to replace dom4j. For the record, with dom4j you could achieve this with similar ease using XMLWriter and OutputFormat. Edit: ...as demonstrated in mlo55's answer.)

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

on (release) {
  getURL("http://someurl/");
}

To make the button transparent you can place a square inside it that is moved to the hit-area frame of the button.

I think it would go too far to explain into depth with pictures how to go about in stackoverflow.

This is a fairly standard communication question. One approach would be to use a ResultReceiver in Activity A:

Intent GotoB=new Intent(A.this,B.class);
GotoB.putExtra("finisher", new ResultReceiver(null) {
    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {
        A.this.finish();
    }
});
startActivityForResult(GotoB,1);

and then in Activity B you can just finish it on demand like so:

((ResultReceiver)getIntent().getExtra("finisher")).send(1, new Bundle());

Try something like that.

Just import the HttpModule and the HttpClientModule only:

import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';

No need for the HttpClient.

The answer is here: How to use C/Cpp extension and add includepath to configurations.

Click the light bulb and then edit the JSON file which is opened. Choose the right block corresponding to your platform (there are Mac, Linux, Win32 – ms-vscode.cpptools version: 3). Update paths in includePath (matters if you compile with VS Code) or browse.paths (matters if you navigate with VS Code) or both.

Thanks to @Francesco Borzì, I will append his answer here:

You have to Left click on the bulb next to the squiggled code line.

If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

You could also set the JDK for Maven in a file in your home directory ~/.mavenrc:

JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk-11.0.5.jdk/Contents/Home'

This environment variable will be checked by the mvn script and used when present:

  if [ -f "$HOME/.mavenrc" ] ; then
    . "$HOME/.mavenrc"
  fi

For business logic I usually find a decimal number (in years) is useful:

select months_between(TRUNC(sysdate),
                      to_date('15-Dec-2000','DD-MON-YYYY')
                     )/12

Open Terminal and type:

pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages

except instead of

/Users/Bob/Library/Python/3.8/lib/python/site-packages

you would use whatever directory you want.

Based on Derek's answer, I verified that

document.getElementById('testTarget')
  .dispatchEvent(new MouseEvent('click', {shiftKey: true}))

works as expected even with key modifiers. And this is not a deprecated API, as far as I can see. You can verify on this page as well.

Try this:

SELECT
   PropertyId,
   SUM(Amount) as TOTAL_COSTS
FROM
   MyTable
WHERE
   EndDate IS NULL
GROUP BY
   PropertyId

OK, after 2 years it's finally time to correct the syntax:

SELECT  t1.value, t2.value
FROM    MyTable t1
JOIN    MyTable t2
ON      t1.id = t2.id
WHERE   t1.id = @id
        AND t1.status = @status1
        AND t2.status = @status2

Consider using axios

axios.get( url,
{ headers: {"Content-Type": "application/json"} } ).then( res => {

  if(res.data.error) {

  } else { 
    doAnything( res.data )
  }

}).catch(function (error) {
   doAnythingError(error)
});

I had this issue using fetch and axios worked perfectly.

Doing college work I gathered the data I found and gave me this result:

"The input consists of a single line with multiple integers, separated by a blank space. The end of the entry is identified by the number -1, which should not be processed."

#include <iostream>
#include <cstdlib>

    int count = 0, soma = 0;

    cin.getline(numeros, 100);

    system("cls"); // limpa a tela

    for(int i = 0; i < 100; i++)
    {

export my store variable

export const store = createStore(rootReducer, applyMiddleware(ReduxThunk));

in action file or your file need them import this (store)

import {store} from "./path...";

this step get sate from store variable with function

const state = store.getState();

and get all of state your app

Use simple onkeypress event inline.

 <input type="text" name="count"  onkeypress="return /[0-9a-zA-Z]/i.test(event.key)">

I use method 3 because it's the most understandable for others (whenever you see an <a> tag, you know it's a link) and when you are part of a team, you have to make simple things ;).

And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.

If you want to match only elements with both classes (an intersection, like a logical AND), just write the selectors together without spaces in between:

$('.a.b')

The order is not relevant, so you can also swap the classes:

$('.b.a')

So to match a div element that has an ID of a with classes b and c, you would write:

$('div#a.b.c')

(In practice, you most likely don't need to get that specific, and an ID or class selector by itself is usually enough: $('#a').)

If you don't like the idea of "reverting a revert" (especially when that means losing history information for many commits), you can always head to the git documentation about "Reverting a faulty merge".

Given the following starting situation

 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E   <-- fixed-up topic branch

(W is your initial revert of the merge M; D and E are fixes to your initially broken feature branch/commit)

You can now simply replay commits A to E, so that none of them "belongs" to the reverted merge:

$ git checkout E
$ git rebase --no-ff P

The new copy of your branch can now be merged to master again:

   A'---B'---C'------------D'---E'  <-- recreated topic branch
  /
 P---o---o---M---x---x---W---x
  \         /
   A---B---C----------------D---E

If you want to use the same function on different events the following code block can be used

$('input').on('keyup blur focus', function () {
   //function block
})

Any collection that you iterate over with foreach may not be modified during iteration.

So while you're running a foreach over rankings, you cannot modify its elements, add new ones or delete any.

Relative Paths

A relative path assumes that the file is on the current server. Using relative paths allows you to construct your site offline and fully test it before uploading it.

For example:

php/webct/itr/index.php

.

Absolute Paths

An absolute path refers to a file on the Internet using its full URL. Absolute paths tell the browser precisely where to go.

For example:

http://www.uvsc.edu/disted/php/webct/itr/index.php

Absolute paths are easier to use and understand. However, it is not good practice on your own website. For one thing, using relative paths allows you to construct your site offline and fully test it before uploading it. If you were to use absolute paths you would have to change your code before uploading it in order to get it to work. This would also be the case if you ever had to move your site or if you changed domain names.

On php 5.3.0 and later version you dont need to specially install mysqli on windows. Rather follow simple steps as shown below.

Locate php.ini file [ if not there it means you have not copied php.ini-development or php.ini-production file as php.ini to make your configurations ]

There are 2 things to be done 1. Uncomment and set right path to extension_dir = "ext" Basically set the path where you find ext folder in php even if its in same folder from where you are running php-cgi.ex

2. uncomment mysqli library extention extension=mysqli

Note: uncommenting in this php.ini file is by removing starting ; from the line.

Okay, I just found the answer (on Stackoverflow, no less).

Eclipse has an option so that copy-paste of multi-line text into String literals will result in quoted newlines:

Preferences/Java/Editor/Typing/ "Escape text when pasting into a string literal"

Reference link: http://www.programering.com/a/MTNyUDMwATA.html

Steps I followed 1) Execute the command adb nodaemon server in command prompt Output at command prompt will be: The following error occurred cannot bind 'tcp:5037' The original ADB server port binding failed

2) Enter the following command query which using port 5037 netstat -ano | findstr "5037" The following information will be prompted on command prompt: TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9288

3) View the task manager, close all adb.exe

4) Restart eclipse or other IDE

The above steps worked for me.

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =

In cs file:

    private DataTable _dataTable;

    public DataTable DataTable
    {
        get { return _dataTable; }
        set { _dataTable = value; }
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        this._dataTable = new DataTable("table");

        this._dataTable.Columns.Add("col0");
        this._dataTable.Columns.Add("col1");
        this._dataTable.Columns.Add("col2");

        this._dataTable.Rows.Add("data00", "data01", "data02");
        this._dataTable.Rows.Add("data10", "data11", "data22");
        this._dataTable.Rows.Add("data20", "data21", "data22");

        this.grid1.DataContext = this;

    }

In Xaml file:

<DataGrid x:Name="grid1"
          Margin="10"
          AutoGenerateColumns="True"
          ItemsSource="{Binding Path=DataTable, Mode=TwoWay}" />

Put the background url in quotes.

It should be background: url('background.png');

See here for working demo.

You also have an issue with the background-repeat line missing a semicolon in between two statements. If your background is really tiny you won't see it because of that issue.

Just to update on the solution, among the other issues, the background file was being refrenced with .../background.jpg when it should have been ../background.jpg (2 dots, not 3).

In addition to VonC's answer, you could tweak it to your liking even further.

After fetching from the remote branch, you would still have to merge the commits. I would replace

$ git fetch upstream

with

$ git pull upstream master

since git pull is essentially git fetch + git merge.

You cannot. Instead if you machine is named "myMachine", point your browser to http://mymachine instead of http://localhost

Using plain javascript

<html>

  <head>

     <!-- define on/off styles -->
     <style type="text/css">
      .on  { background:blue; }
      .off { background:red; }
     </style>

     <!-- define the toggle function -->
     <script language="javascript">
        function toggleState(item){
           if(item.className == "on") {
              item.className="off";
           } else {
              item.className="on";
           }
        }
     </script>
  </head>

  <body>
     <!-- call 'toggleState' whenever clicked -->
     <input type="button" id="btn" value="button" 
        class="off" onclick="toggleState(this)" />
  </body>

</html>

Using jQuery

If you use jQuery, you can do it using the toggle function, or using the toggleClass function inside click event handler, like this:

$(document).ready(function(){
    $('a#myButton').click(function(){
        $(this).toggleClass("btnClicked");
    });
});

Using jQuery UI effects, you can animate transitions: http://jqueryui.com/demos/toggleClass/

I just found some issues on FAB and I want to enhance another answer.

setRippleColor issue

So, the issue will come once you set the ripple color (FAB color on pressed) programmatically through setRippleColor. But, we still have an alternative way to set it, i.e. by calling:

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
ColorStateList rippleColor = ContextCompat.getColorStateList(context, R.color.fab_ripple_color);
fab.setBackgroundTintList(rippleColor);

Your project need to has this structure:

/res/color/fab_ripple_color.xml

And the code from fab_ripple_color.xml is:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:color="@color/fab_color_pressed" />
    <item android:state_focused="true" android:color="@color/fab_color_pressed" />
    <item android:color="@color/fab_color_normal"/>
</selector>

Finally, alter your FAB slightly:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_add"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    app:fabSize="normal"
    app:borderWidth="0dp"
    app:elevation="6dp"
    app:pressedTranslationZ="12dp"
    app:rippleColor="@android:color/transparent"/> <!-- set to transparent color -->

For API level 21 and higher, set margin right and bottom to 24dp:

...
android:layout_marginRight="24dp"
android:layout_marginBottom="24dp" />

FloatingActionButton design guides

As you can see on my FAB xml code above, I set:

        ...
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        app:elevation="6dp"
        app:pressedTranslationZ="12dp"
        ...

• By setting these attributes, you don't need to set layout_marginTop and layout_marginRight again (only on pre-Lollipop). Android will place it automatically on the right corned side of the screen, which the same as normal FAB in Android Lollipop.

      android:layout_alignParentBottom="true"
      android:layout_alignParentRight="true"
  

Or, you can use this in CoordinatorLayout:

        android:layout_gravity="end|bottom"

• You need to have 6dp elevation and 12dp pressedTranslationZ, according to this guide from Google.

You can make use of scaffold_controller and remember to pass the attributes of the model, or scaffold will be generated without the attributes.

rails g scaffold_controller User name email
# or
rails g scaffold_controller User name:string email:string

This command will generate following files:

create  app/controllers/users_controller.rb
invoke  haml
create    app/views/users
create    app/views/users/index.html.haml
create    app/views/users/edit.html.haml
create    app/views/users/show.html.haml
create    app/views/users/new.html.haml
create    app/views/users/_form.html.haml
invoke  test_unit
create    test/controllers/users_controller_test.rb
invoke  helper
create    app/helpers/users_helper.rb
invoke    test_unit
invoke  jbuilder
create    app/views/users/index.json.jbuilder
create    app/views/users/show.json.jbuilder

You need to define an AbstractBinder and register it in your JAX-RS application. The binder specifies how the dependency injection should create your classes.

public class MyApplicationBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(MyService.class).to(MyService.class);
    }
}

When @Inject is detected on a parameter or field of type MyService.class it is instantiated using the class MyService. To use this binder, it need to be registered with the JAX-RS application. In your web.xml, define a JAX-RS application like this:

<servlet>
  <servlet-name>MyApplication</servlet-name>
  <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>com.mypackage.MyApplication</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>MyApplication</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

Implement the MyApplication class (specified above in the init-param).

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        register(new MyApplicationBinder());
        packages(true, "com.mypackage.rest");
    }
}

The binder specifying dependency injection is registered in the constructor of the class, and we also tell the application where to find the REST resources (in your case, MyResource) using the packages() method call.

Another solution, based on @Kitet's.

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");
header("Status: 404 Not Found");

$_SERVER['REDIRECT_STATUS'] = 404;
//If you don't know which web page is in use, use any page that doesn't exists
$handle = curl_init('http://'. $_SERVER["HTTP_HOST"] .'/404missing.html');
curl_exec($handle);

If you are programming a website that hosted in a server you do not have control, you will not know which file is the "404missing.html". However you can still do this.

In this way, you provided exactly the same outcome of a normal 404 page on the same server. An observer will not be able to distinguish between an existing PHP page returns 404 and a non-existing page.

Instead of

<div class="col-md-4"></div>
<div class="col-md-4"></div>
<div class="col-md-4"></div>

You could just use

<div class="col-md-4 col-md-offset-4"></div>

As long as you don't want anything in columns 1 & 3 this is a more elegant solution. The offset "adds" 4 columns in front, leaving you with 4 "spare" after.

PS I realise that the initial question specifies no offsets but at least one previous answer uses a CSS hack that is unnecessary if you use offsets. So for completeness' sake I think this is valid.

No, VBA does not have this functionality. You can use the technique of adding each item to a collection using the item as the key. Since a collection does not allow duplicate keys, the result is distinct values that you can copy to an array, if needed.

You may also want something more robust. See Distinct Values Function at http://www.cpearson.com/excel/distinctvalues.aspx

Distinct Values Function

A VBA Function that will return an array of the distinct values in a range or array of input values.

Excel has some manual methods, such as Advanced Filter, for getting a list of distinct items from an input range. The drawback of using such methods is that you must manually refresh the results when the input data changes. Moreover, these methods work only with ranges, not arrays of values, and, not being functions, cannot be called from worksheet cells or incorporated into array formulas. This page describes a VBA function called DistinctValues that accepts as input either a range or an array of data and returns as its result an array containing the distinct items from the input list. That is, the elements with all duplicates removed. The order of the input elements is preserved. The order of the elements in the output array is the same as the order in the input values. The function can be called from an array entered range on a worksheet (see this page for information about array formulas), or from in an array formula in a single worksheet cell, or from another VB function.

method 1 <input type="text" onclick="this.disabled=false;" disabled>
<hr>
method 2 <input type="text" onclick="this.removeAttribute('disabled');" disabled>
<hr>
method 3 <input type="text" onclick="this.removeAttribute('readonly');" readonly>

code of the previous answers don't seem to work in inline mode, but there is a workaround: method 3.

see demo https://jsfiddle.net/eliz82/xqzccdfg/

Iterating a list and removing multiple items using a find. Response contains an array of integers. $('#OneSelectList') is a select list.

$.ajax({

    type: "GET",
    success: function (response) {
        // Take out excluded years.
        $.each(response, function (j, responseYear) {
            $('#OneSelectList').find('[value="' + responseYear + '"]').remove();

Use the classes found in the java.nio namespace, in particular, the ByteBuffer. It can do all the work for you.

byte[] arr = { 0x00, 0x01 };
ByteBuffer wrapped = ByteBuffer.wrap(arr); // big-endian by default
short num = wrapped.getShort(); // 1

ByteBuffer dbuf = ByteBuffer.allocate(2);
dbuf.putShort(num);
byte[] bytes = dbuf.array(); // { 0, 1 }

you can try something like this:

import java.io.*;
import java.util.*;
class FindFile 
{
    public void findFile(String name,File file)
    {
        File[] list = file.listFiles();
        if(list!=null)
        for (File fil : list)
        {
            if (fil.isDirectory())
            {
                findFile(name,fil);
            }
            else if (name.equalsIgnoreCase(fil.getName()))
            {
                System.out.println(fil.getParentFile());
            }
        }
    }
    public static void main(String[] args) 
    {
        FindFile ff = new FindFile();
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter the file to be searched.. " );
        String name = scan.next();
        System.out.println("Enter the directory where to search ");
        String directory = scan.next();
        ff.findFile(name,new File(directory));
    }
}

Here is the output:

J:\Java\misc\load>java FindFile
Enter the file to be searched..
FindFile.java
Enter the directory where to search
j:\java\
FindFile.java Found in->j:\java\misc\load

I had this problem. My solution is: change same password of other in windowns. Restart Service (check logon in tab Service SQL).

The issue stems from your Angular code:

When withCredentials is set to true, it is trying to send credentials or cookies along with the request. As that means another origin is potentially trying to do authenticated requests, the wildcard ("*") is not permitted as the "Access-Control-Allow-Origin" header.

You would have to explicitly respond with the origin that made the request in the "Access-Control-Allow-Origin" header to make this work.

I would recommend to explicitly whitelist the origins that you want to allow to make authenticated requests, because simply responding with the origin from the request means that any given website can make authenticated calls to your backend if the user happens to have a valid session.

I explain this stuff in this article I wrote a while back.

So you can either set withCredentials to false or implement an origin whitelist and respond to CORS requests with a valid origin whenever credentials are involved

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

Use ImageView... it have transparent background by default...

Use the code below it worked for me.

MediaPlayer mp = new MediaPlayer();
mp.setDataSource("/mnt/sdcard/yourdirectory/youraudiofile.mp3");
mp.prepare();
mp.start();

I am using ipython 2.0, so just two line.

pushing a value (not necessarily stored in a register) means writing it to the stack.

popping means restoring whatever is on top of the stack into a register. Those are basic instructions:

push 0xdeadbeef      ; push a value to the stack
pop eax              ; eax is now 0xdeadbeef

; swap contents of registers
push eax
mov eax, ebx
pop ebx

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

Is the opaque overlay for aesthetic purposes?

If so, you can use:

#overlay {
        position: fixed;
        top: 0;
        right: 0;
        bottom: 0;
        left: 0;
        z-index: 50;
        background: #000;
        pointer-events: none;
        opacity: 0.8;
        color: #fff;
}

'pointer-events: none' will change the overlay behavior so that it can be physically opaque. Of course, this will only work in good browsers.

Feedback loops in a hierarchical organization.

Top boss tells top executives to collect feedback from everyone in the company.

Each executive gathers his/her direct reports and tells them to gather feedback from their direct reports.

And on down the line.

People with no direct reports -- the leaf nodes in the tree -- give their feedback.

The feedback travels back up the tree with each manager adding his/her own feedback.

Eventually all the feedback makes it back up to the top boss.

This is the natural solution because the recursive method allows filtering at each level -- the collating of duplicates and the removal of offensive feedback. The top boss could send a global email and have each employee report feedback directly back to him/her, but there are the "you can't handle the truth" and the "you're fired" problems, so recursion works best here.

You can get clean and clear solutions by building the appropriate predicates as helper functions. In other words, use the Python set-builder notation the same way you would write the answer with regular mathematics set-notation.

The whole idea behind set comprehensions is to let us write and reason in code the same way we do mathematics by hand.

With an appropriate predicate in hand, problem 1 simplifies to:

 low_primes = {x for x in range(1, 100) if is_prime(x)}

And problem 2 simplifies to:

 low_prime_pairs = {(x, x+2) for x in range(1,100,2) if is_prime(x) and is_prime(x+2)}

Note how this code is a direct translation of the problem specification, "A Prime Pair is a pair of consecutive odd numbers that are both prime."

P.S. I'm trying to give you the correct problem solving technique without actually giving away the answer to the homework problem.

A modern ES6 approach. Select the form with any method you like. Use the spread operator to convert HTMLFormControlsCollection to an Array, then the forEach method is available. [...form.elements].forEach

Update: Array.from is a nicer alternative to spread Array.from(form.elements) it's slightly clearer behaviour.

An example below iterates over every input in the form. You can filter out certain input types by checking input.type != "submit"

const forms = document.querySelectorAll('form');
const form = forms[0];

Array.from(form.elements).forEach((input) => {
  console.log(input);
});

<div>
  <h1>Input Form Selection</h1>
  <form>
    <label>
      Foo
      <input type="text" placeholder="Foo" name="Foo" />
    </label>
    <label>
      Password
      <input type="password" placeholder="Password" />
    </label>
    <label>
      Foo
      <input type="text" placeholder="Bar" name="Bar" />
    </label>
    <span>Ts &amp; Cs</span>
    <input type="hidden" name="_id" />
    <input type="submit" name="_id" />
  </form>
</div>

You might want to start with an introduction to version control. This guide is specific to subversion, but the core concepts can be applied to most version control systems. After you have the basics, you can delve into the git guide.

The values() method returns a QuerySet containing dictionaries:

<QuerySet [{'comment_id': 1}, {'comment_id': 2}]>

The values_list() method returns a QuerySet containing tuples:

<QuerySet [(1,), (2,)]>

If you are using values_list() with a single field, you can use flat=True to return a QuerySet of single values instead of 1-tuples:

<QuerySet [1, 2]>

Use a binding, like in this example:

<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
  Search Manager
</a>

var ViewModelStructure = function () {
    var self = this;
    this.SearchManager = function (search) {
        console.log(search);
    };
}();

Another way is to use a website thumbnail/link preview service LinkPeek (even happens to show a screenshot of StackOverflow as a demo right now), URL2PNG, Browshot, Websnapr, or an alternative.

Perhaps not exactly what you asked, but I find this to be useful to put at the start of my programs:

import sys

if sys.version_info[0] < 3:
    raise Exception("Python 3 or a more recent version is required.")

An alternative strict solution using the standard library is to perform the following:

1) Create a strict SimpleDateFormat using your pattern

2) Attempt to parse the user entered value using the format object

3) If successful, reformat the Date resulting from (2) using the same date format (from (1))

4) Compare the reformatted date against the original, user-entered value. If they're equal then the value entered strictly matches your pattern.

This way, you don't need to create complex regular expressions - in my case I needed to support all of SimpleDateFormat's pattern syntax, rather than be limited to certain types like just days, months and years.

As stated in this answer not all browsers support the standard way. It is not a good idea to use for robust user experience. And if you use it, you cannot ask too much.

Instead use time-picker libraries. For example: TimePicker.js is a zero dependency and lightweight library. Use it like:

var timepicker = new TimePicker('time', {_x000D_
  lang: 'en',_x000D_
  theme: 'dark'_x000D_
});_x000D_
timepicker.on('change', function(evt) {_x000D_
  _x000D_
  var value = (evt.hour || '00') + ':' + (evt.minute || '00');_x000D_
  evt.element.value = value;_x000D_
_x000D_
});

<script src="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.js"></script>_x000D_
<link href="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.css" rel="stylesheet"/>_x000D_
_x000D_
<div>_x000D_
  <input type="text" id="time" placeholder="Time">_x000D_
</div>

The problem with using the git hash as the build number is that it's not monotonically increasing. OSGi suggests using a time-stamp for the build number. It looks like the number of commits to the branch could be used in place of the subversion or perforce change number.

Disable Instant Run

Settings>Build, Execution, Deployment>Instant Run

Source: comment by @Shubham A.

Edit: To Disable Instant run

In Windows:

1. Open Find Action: Control + Shift + A.
2. Search instant run and open instant run under settings.
3. Uncheck Enable instant run...

In Mac: I don't have a mac, so try like

1. Open Find Action: Command + Shift + A.
2. Search instant run and open instant run under settings.
3. Uncheck Enable instant run...

For concatenating it's:

input[name="Sex"][value="M"] {}

And for taking union it's:

input[name="Sex"], input[value="M"] {}

EX:

<input type="textbox" ondrop="return false;" onpaste="return false;">

Use these attributes in the required textbox in HTML. Now the drag-and-drop and the paste functionality are disabled.

Why not just

$q->where("a = 1");
$q->andWhere("b = 1 OR b = 2");
$q->andWhere("c = 1 OR d = 2");

EDIT: You can also use the Expr class (Doctrine2).

I ended up here and my issue was that I was querying for

{$not: {email: /@domain.com/}}

instead of

{email: {$not: /@domain.com/}}

You can return dynamic which will give you a runtime checked version of the anonymous type but only in .NET 4+

The python standard library does it...

try:
    # Python3
    import tkinter as tk
except ImportError:
    # Python2
    import Tkinter as tk

def getClipboardText():
    root = tk.Tk()
    # keep the window from showing
    root.withdraw()
    return root.clipboard_get()

Apache Commons Lang has a Range class for doing arbitrary ranges.

Range<Integer> test = Range.between(1, 3);
System.out.println(test.contains(2));
System.out.println(test.contains(4));

Guava Range has similar API.

If you are just wanting to check if a number fits into a long value or an int value, you could try using it through BigDecimal. There are methods for longValueExact and intValueExact that throw exceptions if the value is too big for those precisions.

There is also a nice function get_legend_handles_labels() you can call on the last axis (if you iterate over them) that would collect everything you need from label= arguments:

handles, labels = ax.get_legend_handles_labels()
fig.legend(handles, labels, loc='upper center')

If you want to send ICMP packets in php you can take a look at this Native-PHP ICMP ping implementation, but I didn't test it.

EDIT:

Maybe the site was hacked because it seems that the files got deleted, there is copy in archive.org but you can't download the tar ball file, there are no contact email only contact form, but this will not work at archive.org, we can only wait until the owner will notice that sit is down.

One way is to use a setter for the ngIf property and set the state as part of updating the value.

I acknowledge and agree with hadley (and others), that separate y-scales are "fundamentally flawed". Having said that – I often wish ggplot2 had the feature – particularly, when the data is in wide-format and I quickly want to visualise or check the data (i.e. for personal use only).

While the tidyverse library makes it fairly easy to convert the data to long-format (such that facet_grid() will work), the process is still not trivial, as seen below:

library(tidyverse)
df.wide %>%
    # Select only the columns you need for the plot.
    select(date, column1, column2, column3) %>%
    # Create an id column – needed in the `gather()` function.
    mutate(id = n()) %>%
    # The `gather()` function converts to long-format. 
    # In which the `type` column will contain three factors (column1, column2, column3),
    # and the `value` column will contain the respective values.
    # All the while we retain the `id` and `date` columns.
    gather(type, value, -id, -date) %>%
    # Create the plot according to your specifications
    ggplot(aes(x = date, y = value)) +
        geom_line() +
        # Create a panel for each `type` (ie. column1, column2, column3).
        # If the types have different scales, you can use the `scales="free"` option.
        facet_grid(type~., scales = "free")

I created this methods, it works for me...

public String GetDay() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("dd")));
}

public String GetNameOfTheDay() {
    return String.valueOf(LocalDateTime.now().getDayOfWeek());

public String GetMonth() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("MM")));
}

public String GetNameOfTheMonth() {
    return String.valueOf(LocalDateTime.now().getMonth());
}

public String GetYear() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy")));
}

public boolean isLeapYear(long year) {
    return Year.isLeap(year);
}

public String GetDate() {
    return GetDay() + "/" + GetMonth() + "/" + GetYear();
}

public String Get12HHour() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("hh")));
}

public String Get24HHour() {
    return String.valueOf(LocalDateTime.now().getHour());
}

public String GetMinutes() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("mm")));
}

public String GetSeconds() {
    return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("ss")));

}

for the main question:

call sibling folder as module:

from .. import siblingfolder

call a_file.py from sibling folder as module:

from ..siblingfolder import a_file

call a_function inside a file in sibling folder as module:

from..siblingmodule.a_file import func_name_exists_in_a_file

The easiest way.

go to lib/site-packages folder.

if exists 'easy_install.pth' file, just edit it and add your directory that you have script that you want make it as module.

if not exists, just make it one...and put your folder that you want there

after you add it..., python will be automatically perceive that folder as similar like site-packages and you can call every script from that folder or subfolder as a module.

i wrote this by my phone, and hard to set it to make everyone comfortable to read.

Another option is to pass the single quote as an awk variable:

awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'

Simpler example with string concatenation:

# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'

You can use this function if you want to add the data into database, with a button. I hope it will help.

// dgvBill is name of DataGridView

string StrQuery;
try
{
    using (SqlConnection conn = new SqlConnection(ConnectingString))
    {
        using (SqlCommand comm = new SqlCommand())
        {
            comm.Connection = conn;
            conn.Open();
            for (int i = 0; i < dgvBill.Rows.Count; i++) 
            {
                StrQuery = @"INSERT INTO tblBillDetails (IdBill, productID, quantity, price,  total) VALUES ('" + IdBillVar+ "','" + dgvBill.Rows[i].Cells[0].Value + "', '" + dgvBill.Rows[i].Cells[4].Value + "', '" + dgvBill.Rows[i].Cells[3].Value + "', '" + dgvBill.Rows[i].Cells[2].Value + "');";
                comm.CommandText = StrQuery;

         }
     }
 }
 catch (Exception err)
 {
     MessageBox.Show(err.Message  , "Error !");
 }

Try this:

$('div.btn-group ul.dropdown-menu li a').click(function (e) {
    var $div = $(this).parent().parent().parent(); 
    var $btn = $div.find('button');
    $btn.html($(this).text() + ' <span class="caret"></span>');
    $div.removeClass('open');
    e.preventDefault();
    return false;

Well, what helped me was simply making a copy of the repo folder with everything including the .git folder and working from the copy.

1. I made a copy of the repo folder
2. I navigated into the copy and deleted the .git/index.lock file & then i was able to initiate a PR
3. I deleted my original repo folder
4. I renamed the copy to the original

That worked for me.

To answer your question:

In my Dockerfile, I would like to define variables that I can use later in the Dockerfile.

You can define a variable with:

ARG myvalue=3

Spaces around the equal character are not allowed.

And use it later with:

RUN echo $myvalue > /test

I was able to get rid of my scroll bar on the body of text by removing my max-height attribute of my class.

You can only use aggregates for comparison in the HAVING clause:

GROUP BY ...
  HAVING SUM(cash) > 500

The HAVING clause requires you to define a GROUP BY clause.

To get the first row where the sum of all the previous cash is greater than a certain value, use:

SELECT y.id, y.cash
  FROM (SELECT t.id,
               t.cash,
               (SELECT SUM(x.cash)
                  FROM TABLE x
                 WHERE x.id <= t.id) AS running_total
         FROM TABLE t
     ORDER BY t.id) y
 WHERE y.running_total > 500
ORDER BY y.id
   LIMIT 1

Because the aggregate function occurs in a subquery, the column alias for it can be referenced in the WHERE clause.

RFC6648 recommends that you assume that your custom header "might become standardized, public, commonly deployed, or usable across multiple implementations." Therefore, it recommends not to prefix it with "X-" or similar constructs.

However, there is an exception "when it is extremely unlikely that [your header] will ever be standardized." For such "implementation-specific and private-use" headers, the RFC says a namespace such as a vendor prefix is justified.

If my understanding is correct, updates should be pretty simple. I would just do the following.

UPDATE TABLE SET QUANTITY = QUANTITY + 1 and
UPDATE TABLE SET QUANTITY = QUANTITY - 1 where QUANTITY > 0

You may need additional filters to just update a single row instead of all the rows.

For inserts, you can cache some unique id related to your record locally and check against this cache and decide whether to insert or not. The alternative approach is to always insert and check for PK violation error and ignore since this is a redundant insert.

This will add a new column to your data.frame with the specified format.

df$Month_Yr <- format(as.Date(df$Date), "%Y-%m")

df
#>   ID       Date Month_Yr
#> 1  1 2004-02-06  2004-02
#> 2  2 2006-03-14  2006-03
#> 3  3 2007-07-16  2007-07

# your data sample
  df <- data.frame( ID=1:3,Date = c("2004-02-06" , "2006-03-14" , "2007-07-16") )

a simple example:

dates <- "2004-02-06"

format(as.Date(dates), "%Y-%m")
> "2004-02"

side note: the data.table approach can be quite faster in case you're working with a big dataset.

library(data.table)
setDT(df)[, Month_Yr := format(as.Date(Date), "%Y-%m") ]

As per the official documents, it's not anymore advisable to use matrix class since it will be removed in the future.

https://numpy.org/doc/stable/reference/generated/numpy.matrix.html

As other answers already state that you can achieve all the operations with NumPy arrays.

$limit = (Get-Date).AddDays(-15)
$path = "C:\Some\Path"

# Delete files older than the $limit.
Get-ChildItem -Path $path -Force | Where-Object { !$_.PSIsContainer -and $_.CreationTime -lt $limit } | Remove-Item -Force -Recurse

This will delete old folders and it content.

PDFs may contain binary data and chances are it's getting mangled when you do ToString. It seems to me that you want this:

        FileInputStream inputStream = new FileInputStream(sourcePath);

        int numberBytes = inputStream .available();
        byte bytearray[] = new byte[numberBytes];

        inputStream .read(bytearray);

If you're using rails you can also use in_groups_of:

foo.in_groups_of(3)

table
{ 
margin-left: auto;
margin-right: auto;
}

This will definitely work. Cheers

As if this question hasn't been beaten to a pulp...

Here's one just for whatever curiosity it brings you...

If you're sure that your object will have only string values, you could really exhaust yourself to conjure up this implementation:

var o = { a: '_A', b: '_B', c: '_C' }
  , json = JSON.stringify(o)
  , split = json.split('')
  , nosj = split.reverse()
  , o2 = nosj.join('');

var reversed = o2.replace(/[{}]+/g, function ($1) { return ({ '{':'}', '}':'{' })[$1]; })
  , object = JSON.parse(reversed)
  , value = '_B'
  , eulav = value.split('').reverse().join('');

console.log('>>', object[eulav]);

Maybe there's something useful to build off of here...

Hope this amuses you.

You can manipulate the stylesheets and stylesheet rules themselves with javascript

var sheetCount = document.styleSheets.length;
var lastSheet = document.styleSheets[sheetCount-1];
var ruleCount;
if (lastSheet.cssRules) { // Firefox uses 'cssRules'
    ruleCount = lastSheet.cssRules.length;
}
else if (lastSheet.rules) { / /IE uses 'rules'
    ruleCount = lastSheet.rules.length;
}
var newRule = "a:hover { text-decoration: none !important; color: #000 !important; }";
// insert as the last rule in the last sheet so it
// overrides (not overwrites) previous definitions
lastSheet.insertRule(newRule, ruleCount);

Making the attributes !important and making this the very last CSS definition should override any previous definition, unless one is more specifically targeted. You may have to insert more rules in that case.

My solution:

//Object forEachDone

Object.defineProperty(Array.prototype, "forEachDone", {
    enumerable: false,
    value: function(task, cb){
        var counter = 0;
        this.forEach(function(item, index, array){
            task(item, index, array);
            if(array.length === ++counter){
                if(cb) cb();
            }
        });
    }
});


//Array forEachDone

Object.defineProperty(Object.prototype, "forEachDone", {
    enumerable: false,
    value: function(task, cb){
        var obj = this;
        var counter = 0;
        Object.keys(obj).forEach(function(key, index, array){
            task(obj[key], key, obj);
            if(array.length === ++counter){
                if(cb) cb();
            }
        });
    }
});

Example:

var arr = ['a', 'b', 'c'];

arr.forEachDone(function(item){
    console.log(item);
}, function(){
   console.log('done');
});

// out: a b c done

if you are using phonegap / cordova applications, just edit your config.xml and add the android-versionCode and version in the widget.

<widget id="com.xxx.yyy" version="1.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0" android-versionCode="100001" version="1.0.1">

$books[] = [
            'title' => 'Mytitle',
            'author' => 'MyAuthor,
            
        ];

//pass data to other view
return view('myView.blade.php')->with('books');
or
return view('myView.blade.php','books');
or
return view('myView.blade.php',compact('books'));

----------------------------------------------------


//to use this on myView.blade.php
<script>
    myVariable = {!! json_encode($books) !!};
    console.log(myVariable);
</script>

As of my knowledge it is impossible to alter/modify a table type.You can create the type with a different name and then drop the old type and modify it to the new name

As per msdn, it is like 'The user-defined table type definition cannot be modified after it is created'.
