As per your description, things don't add up. If aSourceDictionary is a dictionary, then your for loop has to work properly.

>>> source = {'a': [1, 2], 'b': [2, 3]}
>>> target = {}
>>> for key in source:
...   target[key] = []
...   target[key].extend(source[key])
... 
>>> target
{'a': [1, 2], 'b': [2, 3]}
>>> 

A more appropriate method is to use std::cin.ignore:

#include <iostream>

void Pause()
{
   std::cout << "Press Enter to continue...";
   std::cout.flush();
   std::cin.ignore(10000, '\n');
   return;
}

Yes. It is done with a filter on the appender.

Here is the appender configuration I normally use, limited to only INFO level.

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="${HOMEDRIVE}\\PI.Logging\\PI.ECSignage.${COMPUTERNAME}.log" />
  <appendToFile value="true" />
  <maxSizeRollBackups value="30" />
  <maximumFileSize value="5MB" />
  <rollingStyle value="Size" />     <!--A maximum number of backup files when rolling on date/time boundaries is not supported. -->
  <staticLogFileName value="false" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%date{yyyy-MM-dd HH:mm:ss.ffff} [%2thread] %-5level %20.20type{1}.%-25method at %-4line| (%-30.30logger) %message%newline" />
  </layout>

  <filter type="log4net.Filter.LevelRangeFilter">
        <levelMin value="INFO" />
        <levelMax value="INFO" />
  </filter>
</appender>    

You can use the Javascript library PDF.JS to display a PDF inside a div. The size of the PDF can be adjusted according to the size of the div. You can also setup event handlers for moving to next / previous pages of the PDF.

You can checkout PDF.JS Tutorial - How to display a PDF with Javascript to see how PDF.JS can be integrated in your HTML code.

It is as simple as

hash.values
#=> [["a", "b", "c"], ["b", "c"]]

this will return a new array populated with the values from hash

if you want to store that new array do

array_of_values = hash.values
#=> [["a", "b", "c"], ["b", "c"]]

array_of_values
 #=> [["a", "b", "c"], ["b", "c"]]

Good Semantics is important in programming.

Utilizing more methods besides GET/POST will be helpful because it will increase the readability of your code and make it easier to maintain.

Why?

Because you know GET will retrieve data from your api. You know POST will add new data to your system. You know PUT will make updates. DELETE will delete rows etc, etc,

I normally structure my RESTFUL Web Services so that I have a function callback named the same thing as the method.

I use PHP, so I use function_exists (I think its called). If the function doesn't exist, I throw a 405 (METHOD NOT ALLOWED).

The answer are accepted but one thing you could also do is to define the libraries from your project structure. What you can do is :

1. Comment all the libraries in which problem is coming
2. Goto your project structure
3. Add libraries from there and it'll sync automatically and the problem goes off.
4. If problem persists try looking from the error log that what library is it demanding after following all the above 3 steps.

What happens is the predefined libraries as off now now I'm taking the appcompat:26.0.0-alpha1 it uses the older version of the things when you add something new and tries to resolve it with the old stuffs. When you add it from your project structure, it'll add the same thing but with the new stuffs to resolve it. Your problem would be resolved.

Simple and dynamic solution (Swift 5):

extension FileManager {

  class func directoryUrl() -> URL? {
      let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
      return paths.first
  }

  class func allRecordedData() -> [URL]? {
     if let documentsUrl = FileManager.directoryUrl() {
        do {
            let directoryContents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil)
            return directoryContents.filter{ $0.pathExtension == "m4a" }
        } catch {
            return nil
        }
     }
     return nil
  }}

I was frustrated by the lack of a fast, high quality way to marshal JSON to a colorized string in Go so I wrote my own Marshaller called ColorJSON.

With it, you can easily produce output like this using very little code:

package main

import (
    "fmt"
    "encoding/json"

    "github.com/TylerBrock/colorjson"
)

func main() {
    str := `{
      "str": "foo",
      "num": 100,
      "bool": false,
      "null": null,
      "array": ["foo", "bar", "baz"],
      "obj": { "a": 1, "b": 2 }
    }`

    var obj map[string]interface{}
    json.Unmarshal([]byte(str), &obj)

    // Make a custom formatter with indent set
    f := colorjson.NewFormatter()
    f.Indent = 4

    // Marshall the Colorized JSON
    s, _ := f.Marshal(obj)
    fmt.Println(string(s))
}

I'm writing the documentation for it now but I was excited to share my solution.

Just extending on the many other excellent answers - if you are using jQuery - you could just do something like

$.fn.getMonthName = function(date) {

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

    return monthNames[date.getMonth()];

};

where date is equal to the var d = new Date(somevalue). The primary advantage of this is per @nickf said about avoiding the global namespace.

A lot of the old TextFX operations like removing empty lines and sorting are available under:

Menu Edit ? Line Operations

Check out this site: http://rubular.com/ Basically the site allows you to enter some example text (what you would be looking for on your site) and then as you build the regular expression it will highlight what is being matched in real time.

Use [^\p{L}\p{Nd}]+ - this matches all (Unicode) characters that are neither letters nor (decimal) digits.

In Java:

String resultString = subjectString.replaceAll("[^\\p{L}\\p{Nd}]+", "");

Edit:

I changed \p{N} to \p{Nd} because the former also matches some number symbols like ¼; the latter doesn't. See it on regex101.com.

simple one:

[[@"first" stringByAppendingString:@"second"] stringByAppendingString:@"third"];

if you have many STRINGS to Concatenate, you should use NSMutableString for better performance

Make sure that you have the correct layout, and that the RecyclerView id is inside the layout. Otherwise, you will be getting this error. I had the same problem, then I noticed the layout was wrong.

    public class ColorsFragment extends Fragment {

         public ColorsFragment() {}

         @Override
         public View onCreateView(LayoutInflater inflater, ViewGroup container,
             Bundle savedInstanceState) {

==> make sure you are getting the correct layout here. R.layout...

             View rootView = inflater.inflate(R.layout.fragment_colors, container, false); 

I work at Auth0 and I was involved in the design of the refresh token feature.

It all depends on the type of application and here is our recommended approach.

Web applications

A good pattern is to refresh the token before it expires.

Set the token expiration to one week and refresh the token every time the user opens the web application and every one hour. If a user doesn't open the application for more than a week, they will have to login again and this is acceptable web application UX.

To refresh the token, your API needs a new endpoint that receives a valid, not expired JWT and returns the same signed JWT with the new expiration field. Then the web application will store the token somewhere.

Mobile/Native applications

Most native applications do login once and only once.

The idea is that the refresh token never expires and it can be exchanged always for a valid JWT.

The problem with a token that never expires is that never means never. What do you do if you lose your phone? So, it needs to be identifiable by the user somehow and the application needs to provide a way to revoke access. We decided to use the device's name, e.g. "maryo's iPad". Then the user can go to the application and revoke access to "maryo's iPad".

Another approach is to revoke the refresh token on specific events. An interesting event is changing the password.

We believe that JWT is not useful for these use cases, so we use a random generated string and we store it on our side.

rt.jar contains all of the compiled class files for the base Java Runtime environment. You should not be messing with this jar file.

For MacOS it is called classes.jar and located under /System/Library/Frameworks/<java_version>/Classes . Same not messing with it rule applies there as well :).

Perhaps this will work?

I encounter the same problem. I inited a bean object in static block like below:

static {
    try{
        mqttConfiguration = SpringBootBeanUtils.<MqttConfiguration>getBean(MqttConfiguration.class);
    }catch (Throwable e){
        System.out.println(e);
    }
 }

Just because the process the my bean obejct inition caused a NPE, I get trouble into it. So I think you should check you static code block carefully.

Easiest Way!!!

1. Right click on project and select "Manage NuGet Packages..."
2. Search for Oracle.ManagedDataAccess. Install it.

If you are using Entity Framework and your Visual Studio Version is 2012 or higher,then

3. Again search for Oracle.ManagedDataAccess.EntityFramework. Install it.
   
4. Use below name spaces in your .cs file:
   using Oracle.ManagedDataAccess.Client;
   using Oracle.ManagedDataAccess.EntityFramework;

Its done. Now restart your visual studio and build your code.

What do these packages do?
After installing these packages no additional Oracle client software is required to be installed to connect to database.

assume series s

s = pd.Series(np.arange(100))

Get quantiles for [.1, .2, .3, .4, .5, .6, .7, .8, .9]

s.quantile(np.linspace(.1, 1, 9, 0))

0.1     9.9
0.2    19.8
0.3    29.7
0.4    39.6
0.5    49.5
0.6    59.4
0.7    69.3
0.8    79.2
0.9    89.1
dtype: float64

OR

s.quantile(np.linspace(.1, 1, 9, 0), 'lower')

0.1     9
0.2    19
0.3    29
0.4    39
0.5    49
0.6    59
0.7    69
0.8    79
0.9    89

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

As this is the first result on google and there's no C++20 answer yet, here's how to use std::chrono to do this:

#include <chrono>

//...

using namespace std::chrono;
int64_t timestamp = duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();

In versions of C++ before 20, system_clock's epoch being Unix epoch is a de-facto convention, but it's not standardized. If you're not on C++20, use at your own risk.

For the times when some fields have a ";" and some do not you can also add a semi-colon to the field and use the same method described.

SET MyText = LEFT(MyText+';', CHARINDEX(';',MyText+';')-1)

Use event.source.window.postMessage to send back to sender.

From Iframe

window.top.postMessage('I am Iframe', '*')
window.onmessage = (event) => {
    if (event.data === 'GOT_YOU_IFRAME') {
        console.log('Parent received successfully.')
    }
}

Then from parent say back.

window.onmessage = (event) => {
    event.source.window.postMessage('GOT_YOU_IFRAME', '*')
}

That's the way to do that: Using OAuth 2.0 for Login.

You may use other authentication methods other then Google's as long as it supports OAuth.

No, there are no dictionaries in php. The closest thing you have is an array. However, an array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index. What do I mean by that?

$array = array(
    "foo" => "bar",
    "bar" => "foo"
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];

The following line is allowed with the above array but would give an error if it was a dictionary.

print $array[0]

Python has both arrays and dictionaries.

Expand your one liner into multiple lines. Then it becomes easy:

f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])

parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)

I just type following keywords in the opened terminal;

1. powershell
2. bash
3. cmd
4. node
5. python (or python3)

See details in the below image. (VSCode version 1.19.1 - windows 10 OS)

It works on VS Code Mac as well. I tried it with VSCode (Version 1.20.1)

Keep in mind that if you're doing a cross-domain Ajax call (by using JSONP) - you can't do it synchronously, the async flag will be ignored by jQuery.

$.ajax({
    url: "testserver.php",
    dataType: 'jsonp', // jsonp
    async: false //IGNORED!!
});

For JSONP-calls you could use:

1. Ajax-call to your own domain - and do the cross-domain call server-side
2. Change your code to work asynchronously
3. Use a "function sequencer" library like Frame.js (this answer)
4. Block the UI instead of blocking the execution (this answer) (my favourite way)

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

I have 1 WorkBook("SOURCE") that contains around 20 Sheets. I want to copy only 1 particular sheet to another Workbook("TARGET") using Excel VBA. Please note that the "TARGET" Workbook doen't exist yet. It should be created at runtime.

Another Way

Sub Sample()
    '~~> Change Sheet1 to the relevant sheet
    '~~> This will create a new workbook with the relevant sheet
    ThisWorkbook.Sheets("Sheet1").Copy

    '~~> Save the new workbook
    ActiveWorkbook.SaveAs "C:\Target.xlsx", FileFormat:=51
End Sub

This will automatically create a new workbook called Target.xlsx with the relevant sheet

Try over-riding CSS using !important

like this

.icon-bar {
   background-color:#FF0000 !important;
}

arr = new int[cols*rows];

If you either don't mind syntax

arr[row * cols + col] = Aij;

or use operator[] overaloading somewhere. This may be more cache-friendly than array of arrays, or may be not, more probably you shouldn't care about it. I just want to point out that a) array of arrays is not only solution, b) some operations are more easier to implement if matrix located in one block of memory. E.g.

for(int i=0;i < rows*cols;++i)
   matrix[i]=someOtherMatrix[i];

one line shorter than

for(int r=0;i < rows;++r)
  for(int c=0;i < cols;++s)
     matrix[r][c]=someOtherMatrix[r][c];

though adding rows to such matrix is more painful

Try this:

echo mysql_result($result, 0);

This is enough because you are only fetching one field of one row.

Yes, you can set cookie in the AJAX request in the server-side code just as you'd do for a normal request since the server cannot differentiate between a normal request or an AJAX request.

AJAX requests are just a special way of requesting to server, the server will need to respond back as in any HTTP request. In the response of the request you can add cookies.

Regarding the performance of a many-to-many table, if you have 2 32-bit ints linking user IDs, your basic data storage for 200,000,000 users averaging 200 friends apiece is just under 300GB.

Obviously, you would need some partitioning and indexing and you're not going to keep that in memory for all users.

There is a simple way to solve this: you can execute php file by cron every 1 minute, and inside php executable file make "if" statement to execute when time "now" like this

<?/** suppose we have 1 hour and 1 minute inteval 01:01 */

$interval_source = "01:01";
$time_now = strtotime( "now" ) / 60;
$interval = substr($interval_source,0,2) * 60 + substr($interval_source,3,2);


if( $time_now % $interval == 0){
/** do cronjob */
}

If you have PHP >= 5.1:

function isWeekend($date) {
    return (date('N', strtotime($date)) >= 6);
}

otherwise:

function isWeekend($date) {
    $weekDay = date('w', strtotime($date));
    return ($weekDay == 0 || $weekDay == 6);
}

You have already staged the changes (presumably by running git add), so in order to get their diff, you need to run:

git diff --cached

(A plain git diff will only show unstaged changes.)

For example:

SELECT owner, table_name
  FROM dba_constraints
 WHERE constraint_name = <<your constraint name>>

will give you the name of the table. If you don't have access to the DBA_CONSTRAINTS view, ALL_CONSTRAINTS or USER_CONSTRAINTS should work as well.

tolist() works fine even if encountered a nested array, say a pandas DataFrame;

my_list = [0,1,2,3,4,5,4,3,2,1,0]
my_dt = pd.DataFrame(my_list)
new_list = [i[0] for i in my_dt.values.tolist()]

print(type(my_list),type(my_dt),type(new_list))

Useful thread and I don't bring much new to the table. The step I took is also part of the description Maxime helpfully points to but some may overlook it. The section is Adding your SSH key to the ssh-agent.

I had already generated my ssh-key but after a reboot I was unable to clone one of my own repositories.

I had to start the ssh-agent and add the private key to this agent in order to clone.

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa

I propose to use

SET time_zone = 'proper timezone';

being done once right after connect to database. and after this all timestamps will be converted automatically when selecting them.

The above answers didn't work for me. Possibly the option names were changed since '11, but the following did the trick for me:

ChartJsProvider.setOptions
  scaleBeginAtZero: true

It can be done by many ways in sql server the most simplest way to do so is: Insert the distinct rows from the duplicate rows table to new temporary table. Then delete all the data from duplicate rows table then insert all data from temporary table which has no duplicates as shown below.

select distinct * into #tmp From table
   delete from table
   insert into table
   select * from #tmp drop table #tmp

   select * from table

Delete duplicate rows using Common Table Expression(CTE)

With CTE_Duplicates as 
(select id,name , row_number() 
over(partition by id,name order by id,name ) rownumber  from table  ) 
delete from CTE_Duplicates where rownumber!=1

For development: use a browser setting: for example, Chrome network tab has a disable cache option.

For production: append a unique query parameter to the request (for example, q?Date.now()) with a server-side rendering framework or pure JavaScript code.

// Pure JavaScript unique query parameter generation
//
//=== myfile.js

function hello() { console.log('hello') };

//=== end of file

<script type="text/javascript">
    document.write('<script type="text/javascript" src="myfile.js?q=' + Date.now() + '">
    // document.write is considered bad practice!
    // We can't use hello() yet
</script>')

<script type="text/javascript">
    hello();
</script>

You can also use MongoDB's geospatial indexing feature to select the documents 'nearest' to a random number.

First, enable geospatial indexing on a collection:

db.docs.ensureIndex( { random_point: '2d' } )

To create a bunch of documents with random points on the X-axis:

for ( i = 0; i < 10; ++i ) {
    db.docs.insert( { key: i, random_point: [Math.random(), 0] } );
}

Then you can get a random document from the collection like this:

db.docs.findOne( { random_point : { $near : [Math.random(), 0] } } )

Or you can retrieve several document nearest to a random point:

db.docs.find( { random_point : { $near : [Math.random(), 0] } } ).limit( 4 )

This requires only one query and no null checks, plus the code is clean, simple and flexible. You could even use the Y-axis of the geopoint to add a second randomness dimension to your query.

As a string extension:

    public static string RemoveIntegers(this string input)
    {
        return Regex.Replace(input, @"[\d-]", string.Empty);
    }

Usage:

"My text 1232".RemoveIntegers(); // RETURNS "My text "

(I thought it might be helpful to lay out the ideas very simply here to summarize the good material posted by @doug, & linked by @duffymo; +1 to each,btw.)

?order tells you which element of the original vector needs to be put first, second, etc., so as to sort the original vector, whereas ?rank tell you which element has the lowest, second lowest, etc., value. For example:

> a <- c(45, 50, 10, 96)
> order(a)  
[1] 3 1 2 4  
> rank(a)  
[1] 2 3 1 4  

So order(a) is saying, 'put the third element first when you sort... ', whereas rank(a) is saying, 'the first element is the second lowest... '. (Note that they both agree on which element is lowest, etc.; they just present the information differently.) Thus we see that we can use order() to sort, but we can't use rank() that way:

> a[order(a)]  
[1] 10 45 50 96  
> sort(a)  
[1] 10 45 50 96  
> a[rank(a)]  
[1] 50 10 45 96  

In general, order() will not equal rank() unless the vector has been sorted already:

> b <- sort(a)  
> order(b)==rank(b)  
[1] TRUE TRUE TRUE TRUE  

Also, since order() is (essentially) operating over ranks of the data, you could compose them without affecting the information, but the other way around produces gibberish:

> order(rank(a))==order(a)  
[1] TRUE TRUE TRUE TRUE  
> rank(order(a))==rank(a)  
[1] FALSE FALSE FALSE  TRUE  

For me changing the build configuration from release to Debug solved the issue.

You can find Build Configuration in Edit Scheme -> Run -> Info -> Build Configuration

Clean your project and re run.

Having the same exact issue with iOS 10.3 and Xcode 8.2.1. I'm not going to download the new Xcode beta just to fix this. Come on Apple!

To anyone reading this, you have to go to https://developer.apple.com/download/ and get the latest version, which might even be the beta, if the stable release doesn't work.

In the future, I would be aware if you update iOS on your devices you may break Xcode/iOS version so update wisely if you want to keep testing on it without jumping through hoops that Apple makes.

If you are making jquery ajax request, dont forget to add

contentType:'application/json'

The instance in which you're using a single character (i.e. | or &) is a bitwise comparison of the results. As long as your language evaluates these expressions to a binary value they should return the same results. As a best practice, however, you should use the logical operator as that's what you mean (I think).

Aahh got it... I got it working :)

Thanks Christopher, your suggesion is correct.

But, finding "Default SMTP Virtual Server" was tricky ;)

Even if you use IIS7 to deploy your web site, you have to open IIS6 Manager to configure SMTP server (why?).

I configured SMTP server as follows to make things work:

1. Open IIS6 Manager using Control Panel --> Administrative Tools.
2. Open SMTP Virtual Server properties.
3. On General tab, Set IP address of the Web server instead of "All Unassigned".
4. In Access tab, click on Relay button, this will open Relay Restrictions dialog.
5. In relay computers list, add the loopback IP address i.e 127.0.0.1 and IP address of the Web server, so that they can pass/relay emails through the SMTP server.

The Output window of Visual Studio 2017 have a menu called Show output from, in my case ASP.NET Core Web Server was the option to select in order to see the printed out, I came across this issue since I had it set to Build so I wasn't seeing the printed out lines at runtime.

Here is my solution (derived from SaraubhM's answer)

**Jump To**: [Hotkeys & Markers](#hotkeys-markers) / [Radii](#radii) / [Route Wizard 2.0](#route-wizard-2-0)

Which gives you:

Jump To: Hotkeys & Markers / Radii / Route Wizard 2.0

Note the changes from and . to - and also the loss of the & in the links.

To count items after some number of items (offset), $qb->setFirstResults() cannot be applied in this case, as it works not as a condition of query, but as an offset of query result for a range of items selected (i. e. setFirstResult cannot be used togather with COUNT at all). So to count items, which are left I simply did the following:

   //in repository class:
   $count = $qb->select('count(p.id)')
      ->from('Products', 'p')
      ->getQuery()
      ->getSingleScalarResult();

    return $count;

    //in controller class:
    $count = $this->em->getRepository('RepositoryBundle')->...

    return $count-$offset;

Anybody knows more clean way to do it?

I just read in the MySQL documentation that SHOW FULL PROCESSLIST by default only lists the threads from your current user connection.

Quote from the MySQL SHOW FULL PROCESSLIST documentation:

If you have the PROCESS privilege, you can see all threads.

So you can enable the Process_priv column in your mysql.user table. Remember to execute FLUSH PRIVILEGES afterwards :)

Sorry being late to the party, but it seems like there is another solution which works perfectly for the case you mentioned.

If you use a recycler view inside a recycler view, it seems to work perfectly fine. I have personally tried and used it, and it seems to give no slowness and no jerkyness at all. Now I am not sure if this is a good practice or not, but nesting multiple recycler views , even nested scroll view slows down. But this seems to work nicely. Please give it a try. I am sure nesting is going to be perfectly fine with this.

I had a similar problem. As you increase the line-height the space above the text increases. It's not padding but it will affect the vertical space between content. I found that adding a -ve top margin seemed to do the trick. It had to be done for all of the different instances of line-height and it varies with font-family too. Maybe this is something which designers need to be more aware of when passing design requirements (?) So for a particular instance of font-family and line-height:

h1 {
    font-family: 'Garamond Premier Pro Regular';
    font-size: 24px;
    color: #001230;
    line-height: 29px;
    margin-top: -5px;    /* CORRECTION FOR LINE-HEIGHT */
}

 $endOfCycle = date("Y-m", mktime(0, 0, 0, date("m", time())+1 , 15, date("m", time())));

Some inputs to NN might not have a 'naturally defined' range of values. For example, the average value might be slowly, but continuously increasing over time (for example a number of records in the database).

In such case feeding this raw value into your network will not work very well. You will teach your network on values from lower part of range, while the actual inputs will be from the higher part of this range (and quite possibly above range, that the network has learned to work with).

You should normalize this value. You could for example tell the network by how much the value has changed since the previous input. This increment usually can be defined with high probability in a specific range, which makes it a good input for network.

C++17 has <experimental\filesystem> which is based on the boost version.

Use std::experimental::filesystem::remove_all to remove recursively.

If you need more control, try std::experimental::filesystem::recursive_directory_iterator.

You can also write your own recursion with the non-resursive version of the iterator.

namespace fs = std::experimental::filesystem;
void IterateRecursively(fs::path path)
{
  if (fs::is_directory(path))
  {
    for (auto & child : fs::directory_iterator(path))
      IterateRecursively(child.path());
  }

  std::cout << path << std::endl;
}

$*

Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

$@

Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

Vim's <leader> key is a way of creating a namespace for commands you want to define. Vim already maps most keys and combinations of Ctrl + (some key), so <leader>(some key) is where you (or plugins) can add custom behavior.

For example, if you find yourself frequently deleting exactly 3 words and 7 characters, you might find it convenient to map a command via nmap <leader>d 3dw7x so that pressing the leader key followed by d will delete 3 words and 7 characters. Because it uses the leader key as a prefix, you can be (relatively) assured that you're not stomping on any pre-existing behavior.

The default key for <leader> is \, but you can use the command :let mapleader = "," to remap it to another key (, in this case).

Usevim's page on the leader key has more information.

>>> mylist = [["%s,%s"%(i,j) for j in range(columns)] for i in range(rows)]
>>> mylist
[['0,0', '0,1', '0,2'], ['1,0', '1,1', '1,2'], ['2,0', '2,1', '2,2']]
>>> zip(*mylist)
[('0,0', '1,0', '2,0'), ('0,1', '1,1', '2,1'), ('0,2', '1,2', '2,2')]
>>> sum(zip(*mylist),())
('0,0', '1,0', '2,0', '0,1', '1,1', '2,1', '0,2', '1,2', '2,2')

After @Arvis reply i decided to dig even deeper and I've written a tech article about this here: http://www.andreabaccega.com/blog/2015/08/16/how-to-avoid-fragments-overlapping-due-to-backstack-nightmare-in-android/

For the lazy developers around. My solution consists in always adding the transactions to the backstack and perform an extra FragmentManager.popBackStackImmediate() when needed (automatically).

The code is very few lines of code and, in my example, I wanted to skip from C to A without jumping back to "B" if the user didn't went deeper in the backstack (ex from C navigates to D).

Hence the code attached would work as follow A -> B -> C (back) -> A & A -> B -> C -> D (back) -> C (back) -> B (back) -> A

where

fm.beginTransaction().replace(R.id.content, new CFragment()).commit()

were issued from "B" to "C" as in the question.

Ok,Ok here is the code :)

public static void performNoBackStackTransaction(FragmentManager fragmentManager, String tag, Fragment fragment) {
  final int newBackStackLength = fragmentManager.getBackStackEntryCount() +1;

  fragmentManager.beginTransaction()
      .replace(R.id.content, fragment, tag)
      .addToBackStack(tag)
      .commit();

  fragmentManager.addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
    @Override
    public void onBackStackChanged() {
      int nowCount = fragmentManager.getBackStackEntryCount();
      if (newBackStackLength != nowCount) {
        // we don't really care if going back or forward. we already performed the logic here.
        fragmentManager.removeOnBackStackChangedListener(this);

        if ( newBackStackLength > nowCount ) { // user pressed back
          fragmentManager.popBackStackImmediate();
        }
      }
    }
  });
}

When you use a code like this:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   // Do something with the key...
   // Encrypt, export, etc.
}

.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET

This means:

1. Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.

2. Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).

To resolve these issues:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   try
   {
      // Do something with the key...
      // Encrypt, export, etc.
   }
   finally
   {
      rsa.PersistKeyInCsp = false;
   }
}

You can use dijkstra's algorithm with negative edges not including negative cycle, but you must allow a vertex can be visited multiple times and that version will lose it's fast time complexity.

In that case practically I've seen it's better to use SPFA algorithm which have normal queue and can handle negative edges.

Perl doesn't have a native boolean type, but you can use comparison of integers or strings in order to get the same behavior. Alan's example is a nice way of doing that using comparison of integers. Here's an example

my $boolean = 0;
if ( $boolean ) {
    print "$boolean evaluates to true\n";
} else {
    print "$boolean evaluates to false\n";
}

One thing that I've done in some of my programs is added the same behavior using a constant:

#!/usr/bin/perl

use strict;
use warnings;

use constant false => 0;
use constant true  => 1;

my $val1 = true;
my $val2 = false;

print $val1, " && ", $val2;
if ( $val1 && $val2 ) {
    print " evaluates to true.\n";
} else {
    print " evaluates to false.\n";
}

print $val1, " || ", $val2;
if ( $val1 || $val2 ) {
    print " evaluates to true.\n";
} else {
    print " evaluates to false.\n";
}

The lines marked in "use constant" define a constant named true that always evaluates to 1, and a constant named false that always evaluates by 0. Because of the way that constants are defined in Perl, the following lines of code fails as well:

true = 0;
true = false;

The error message should say something like "Can't modify constant in scalar assignment."

I saw that in one of the comments you asked about comparing strings. You should know that because Perl combines strings and numeric types in scalar variables, you have different syntax for comparing strings and numbers:

my $var1 = "5.0";
my $var2 = "5";

print "using operator eq\n";
if ( $var1 eq $var2 ) {
    print "$var1 and $var2 are equal!\n";
} else {
    print "$var1 and $var2 are not equal!\n";
}

print "using operator ==\n";
if ( $var1 == $var2 ) {
    print "$var1 and $var2 are equal!\n";
} else {
    print "$var1 and $var2 are not equal!\n";
}

The difference between these operators is a very common source of confusion in Perl.

In the specific case of a String array you could initialize the array using the Split Function as it returns a String array rather than a Variant array:

Dim arrWsNames() As String
arrWsNames = Split("Value1,Value2,Value3", ",")

This allows you to avoid using the Variant data type and preserve the desired type for arrWsNames.

• In SQLDeveloper browse Tools --> Preferences, as shown in below image.
  
  
  
  
• In the Preferences options expand Database --> select Advanced --> under "Tnsnames Directory" --> Browse the directory where tnsnames.ora present.
  
• Then click on Ok, as shown in below diagram.
  tnsnames.ora available at Drive:\oracle\product\10x.x.x\client_x\NETWORK\ADMIN
  
  

Now you can connect via the TNSnames options.

This topic, especially the answer of Xotic750 was very helpful to me. I wanted to generate a json variable to pass it to a php script using ajax. My values were stored into two arrays, and i wanted them in json format. This is a generic example:

valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray1[k];
    myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray2[k];
    myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));

The result in the console Log should be something like this:

{
   "objArray1": {
        "obj1": 121,
        "obj2": 324,
        "obj3": 42,
        "obj4": 31
   },
   "objArray2": {
        "obj1": 232,
        "obj2": 131,
        "obj3": 443
  }
}

Solved issue using below steps :

1) edit file "/etc/apache2/sites-enabled/000-default.conf"

    DocumentRoot "dir_name"

    ServerName <server_IP>

    <Directory "dir_name">
       Options Indexes FollowSymLinks
       AllowOverride None
       Require all granted
    </Directory>

    <Directory "dir_name">
       AllowOverride None
       # Allow open access:
       Require all granted

2) change folder permission sudo chmod -R 777 "dir_name"

For Python:

from boto import utils, ec2
from os import environ

# import keys from os.env or use default (not secure)
aws_access_key_id = environ.get('AWS_ACCESS_KEY_ID', failobj='XXXXXXXXXXX')
aws_secret_access_key = environ.get('AWS_SECRET_ACCESS_KEY', failobj='XXXXXXXXXXXXXXXXXXXXX')

#load metadata , if  = {} we are on localhost
# http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AESDG-chapter-instancedata.html
instance_metadata = utils.get_instance_metadata(timeout=0.5, num_retries=1)
region = instance_metadata['placement']['availability-zone'][:-1]
instance_id = instance_metadata['instance-id']

conn = ec2.connect_to_region(region, aws_access_key_id=aws_access_key_id, aws_secret_access_key=aws_secret_access_key)
# get tag status for our  instance_id using filters
# http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-DescribeTags.html
tags = conn.get_all_tags(filters={'resource-id': instance_id, 'key': 'status'})
if tags:
    instance_status = tags[0].value
else:
    instance_status = None
    logging.error('no status tag for '+region+' '+instance_id)

As rightly said in above answers, by calling flush() we force hibernate to execute the SQL commands on Database. But do understand that changes are not "committed" yet. So after doing flush and before doing commit, if you access DB directly (say from SQL prompt) and check the modified rows, you will NOT see the changes.

This is same as opening 2 SQL command sessions. And changes done in 1 session are not visible to others until committed.

Try this in your styles.xml:

colorPrimary will be the toolbar color.

<resources>

<style name="AppTheme" parent="Theme.AppCompat">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_pressed</item>
    <item name="colorAccent">@color/accent</item>
</style>

Did you build this in Eclipse by the way?

Actually, I was looking for that.

<?php

$url = 'http://example.com/myfolder/sympony.mp3?a=1&b=2#XYZ';
$tmp = @parse_url($url)['path'];
$ext = pathinfo($tmp, PATHINFO_EXTENSION);

var_dump($ext);

You can use foreignobject for more control and placing rich HTML content over rect or circle

    <svg width="250" height="250" xmlns="http://www.w3.org/2000/svg">_x000D_
        <rect x="0" y="0" width="250" height="250" fill="aquamarine" />_x000D_
        <foreignobject x="0" y="0" width="250" height="250">_x000D_
            <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
                <div>Here is a long text that runs more than one line and works as a paragraph</div>_x000D_
                <br />_x000D_
                <div>This is <u>UNDER LINE</u> one</div>_x000D_
                <br />_x000D_
                <div>This is <b>BOLD</b> one</div>_x000D_
                <br />_x000D_
                <div>This is <i>Italic</i> one</div>_x000D_
            </body>_x000D_
        </foreignobject>_x000D_
    </svg>

I have a far more simple solution, it is working for me; it is also a workaround but might be usable and you dont have to change your settings. I assume you can use value that will never be there, then you use it on your WHERE clause

DELETE FROM MyTable WHERE MyField IS_NOT_EQUAL AnyValueNoItemOnMyFieldWillEverHave

I don't like that solution either too much, that's why I am here, but it works and it seems better than what it has been answered

try this

$("label").html(your value); or $("label").text(your value);

There is no difference, in browsers that you can find in the wild these days (that is, excluding things like Netscape 1 that you might find in a museum). There is no reason to suspect that any of them would be deprecated ever, especially since they are all valid in XML, in HTML 4.01, and in HTML5 CR.

There is no reason to use any of them, as opposite to using the Ascii quotation mark (") directly, except in the very special case where you have an attribute value enclosed in such marks and you would like to use the mark inside the value (e.g., title="Hello "world""), and even then, there are almost always better options (like title='Hello "word"' or title="Hello “word”".

If you want to use “smart” quotation marks instead, then it’s a different question, and none of the constructs has anything to do with them. Some people expect notations like " to produce “smart” quotes, but it is easy to see that they don’t; the notations unambiguously denote the Ascii quote ("), as used in computer languages.

FYI if you can want to replace simultaneous muti-linebreaks with single line break then you can use

myString.trim().replaceAll("[\n]{2,}", "\n")

Or replace with a single space

myString.trim().replaceAll("[\n]{2,}", " ")

It is working fine for me, but with a different command:

root@ubuntu:/usr/bin# sudo apt-get install sun-java6

Error message:

Couldn't find package sun-java6.

root@ubuntu:/usr/bin# sudo apt-get install sun-java*

Bam, it worked.

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

Or if you want a simple one-liner:

Person person = JAXB.unmarshal(new StringReader("<?xml ..."), Person.class);

Have a look in the syslogins or sysusers tables in the master schema. Not sure if this still still around in more recent MSSQL versions though. In MSSQL 2005 there are views called sys.syslogins and sys.sysusers.

The error here, is since calling the DataFrame constructor with scalar values (where it expects values to be a list/dict/... i.e. have multiple columns):

pd.DataFrame(d)
ValueError: If using all scalar values, you must must pass an index

You could take the items from the dictionary (i.e. the key-value pairs):

In [11]: pd.DataFrame(d.items())  # or list(d.items()) in python 3
Out[11]:
             0    1
0   2012-07-02  392
1   2012-07-06  392
2   2012-06-29  391
3   2012-06-28  391
...

In [12]: pd.DataFrame(d.items(), columns=['Date', 'DateValue'])
Out[12]:
          Date  DateValue
0   2012-07-02        392
1   2012-07-06        392
2   2012-06-29        391

But I think it makes more sense to pass the Series constructor:

In [21]: s = pd.Series(d, name='DateValue')
Out[21]:
2012-06-08    388
2012-06-09    388
2012-06-10    388

In [22]: s.index.name = 'Date'

In [23]: s.reset_index()
Out[23]:
          Date  DateValue
0   2012-06-08        388
1   2012-06-09        388
2   2012-06-10        388

If you need a directive more advanced, I recomend the solution that I implemnted, correctly tested on Internet Explorer 11, Chrome and FireFox.

I hope it, will be helpfull.

There's much simpler solution today — pem. This tool makes life much easier.

For example, to generate or renew your push notification certificate just enter:

fastlane pem 

and it's done in under a minute. In case you need a sandbox certificate, enter:

fastlane pem --development

And that's pretty it.

You might also have a use case where you want to delete a block of text and replace it .

Like this

Hello World
Hello World

You can visual block select before "W" and hit Shift+i - Type "Cool" - Hit ESC and then delete "World" by visual block selection .

Alternatively, the cooler way to do it is to just visual block select "World" in both lines. Type c for change. Now you are in the insert mode. Insert the stuff you want and hit ESC. Both gets reflected with lesser keystrokes.

Hello Cool 
Hello Cool

There is the easy way

HTML:

<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]"  />y
<input type="checkbox" name="test[]" />z
<button type="button" id="submit">Submit</button>

JQUERY:

$("#submit").on("click",function(){
    if (($("input[name*='test']:checked").length)<=0) {
        alert("You must check at least 1 box");
    }
    return true;
});

For this you not need any plugin. Enjoy;)

Fundamentally, in C, "types" are a way to interpret bytes in memory. For example, what the following code

struct Point {
  int x;
  int y;
};

int main() {
  struct Point p;
  p.x = 0;
  p.y = 0;
}

Says "When I run main, I want to allocate 4 (size of integer) + 4 (size of integer) = 8 (total bytes) of memory. When I write '.x' as a lvalue on a value with the type label Point at compile time, retrieve data from the pointer's memory location plus four bytes. Give the return value the compile-time label "int.""

Inside the computer at runtime, your "Point" structure looks like this:

00000000 00000000 00000000 00000000 00000000 00000000 00000000

And here's what your void* data type might look like: (assuming a 32-bit computer)

10001010 11111001 00010010 11000101

You can use the convert statement in Microsoft SQL Server to convert a date to a string. An example of the syntax used would be:

SELECT convert(varchar(20), getdate(), 120)

The above would return the current date and time in a string with the format of YYYY-MM-DD HH:MM:SS in 24 hour clock.

You can change the number at the end of the statement to one of many which will change the returned strings format. A list of these codes can be found on the MSDN in the CAST and CONVERT reference section.

Notes.Select(x => x.Author).Distinct();

This will return a sequence (IEnumerable<string>) of Author values -- one per unique value.

Decimal has a fixed precision while float has variable precision.

EDIT (failed to read entire question): Float(53) (aka real) is a double-precision (64-bit) floating point number in SQL Server. Regular Float is a single-precision (32-bit) floating point number. Double is a good combination of precision and simplicty for a lot of calculations. You can create a very high precision number with decimal -- up to 136-bit -- but you also have to be careful that you define your precision and scale correctly so that it can contain all your intermediate calculations to the necessary number of digits.

Just add these lines

     override fun onBackPressed() {
            if(navController.popBackStack().not()) {
            //Last fragment: Do your operation here 
            finish()
   } 

navController.popBackStack() will just pop your fragment if this is not your last fragment

You can also access through docker exec command by:

$ docker exec -it postgres-container bash

# su postgres

$ psql

Or

$ docker exec -it postgres-container psql -U postgres

I think you are looking for std::any_of, which will return a true/false answer to detect if an element is in a container (array, vector, deque, etc.)

int val = SOME_VALUE; // this is the value you are searching for
bool exists = std::any_of(std::begin(myArray), std::end(myArray), [&](int i)
{
    return i == val;
});

If you want to know where the element is, std::find will return an iterator to the first element matching whatever criteria you provide (or a predicate you give it).

int val = SOME_VALUE;
int* pVal = std::find(std::begin(myArray), std::end(myArray), val);
if (pVal == std::end(myArray))
{
    // not found
}
else
{
    // found
}

The new testing improvements that debuted in Spring Boot 1.4.M2 can help reduce the amount of code you need to write situation such as these.

The test would look like so:

import static org.springframework.test.web.servlet.request.MockMvcRequestB??uilders.get; 
import static org.springframework.test.web.servlet.result.MockMvcResultMat??chers.content; 
import static org.springframework.test.web.servlet.result.MockMvcResultMat??chers.status;

    @RunWith(SpringRunner.class)
    @WebMvcTest(HelloWorld.class)
    public class UserVehicleControllerTests {

        @Autowired
        private MockMvc mockMvc;

        @Test
        public void testSayHelloWorld() throws Exception {
            this.mockMvc.perform(get("/").accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
                    .andExpect(status().isOk())
                    .andExpect(content().contentType("application/json"));

        }

    }

Suprised no-one has yet mentioned the recommended solution in the Python 3 docs:

See also:

• The linspace recipe shows how to implement a lazy version of range that suitable for floating point applications.

Once defined, the recipe is easy to use and does not require numpy or any other external libraries, but functions like numpy.linspace(). Note that rather than a step argument, the third num argument specifies the number of desired values, for example:

print(linspace(0, 10, 5))
# linspace(0, 10, 5)
print(list(linspace(0, 10, 5)))
# [0.0, 2.5, 5.0, 7.5, 10]

I quote a modified version of the full Python 3 recipe from Andrew Barnert below:

import collections.abc
import numbers

class linspace(collections.abc.Sequence):
    """linspace(start, stop, num) -> linspace object

    Return a virtual sequence of num numbers from start to stop (inclusive).

    If you need a half-open range, use linspace(start, stop, num+1)[:-1].
    """
    def __init__(self, start, stop, num):
        if not isinstance(num, numbers.Integral) or num <= 1:
            raise ValueError('num must be an integer > 1')
        self.start, self.stop, self.num = start, stop, num
        self.step = (stop-start)/(num-1)
    def __len__(self):
        return self.num
    def __getitem__(self, i):
        if isinstance(i, slice):
            return [self[x] for x in range(*i.indices(len(self)))]
        if i < 0:
            i = self.num + i
        if i >= self.num:
            raise IndexError('linspace object index out of range')
        if i == self.num-1:
            return self.stop
        return self.start + i*self.step
    def __repr__(self):
        return '{}({}, {}, {})'.format(type(self).__name__,
                                       self.start, self.stop, self.num)
    def __eq__(self, other):
        if not isinstance(other, linspace):
            return False
        return ((self.start, self.stop, self.num) ==
                (other.start, other.stop, other.num))
    def __ne__(self, other):
        return not self==other
    def __hash__(self):
        return hash((type(self), self.start, self.stop, self.num))

None of the current answers including the accepted one will use Apple's San Francisco font on systems that don't have it installed as the system font. Since the question isn't "how do I use the OS X system font on a webpage" the correct solution is to use web fonts:

@font-face {
  font-family: "San Francisco";
  font-weight: 400;
  src: url("https://applesocial.s3.amazonaws.com/assets/styles/fonts/sanfrancisco/sanfranciscodisplay-regular-webfont.woff");

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}

If you're interested in seeing which specific headers a remote client is sending to your server, and you can cause the request to run a CGI script, then the simplest solution is to have your server script dump the environment variables into a file somewhere.

e.g. run the shell command "env > /tmp/headers" from within your script

Then, look for the environment variables that start with HTTP_...

You will see lines like:

HTTP_ACCEPT=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
HTTP_ACCEPT_ENCODING=gzip, deflate
HTTP_ACCEPT_LANGUAGE=en-US,en;q=0.5
HTTP_CACHE_CONTROL=max-age=0

Each of those represents a request header.

Note that the header names are modified from the actual request. For example, "Accept-Language" becomes "HTTP_ACCEPT_LANGUAGE", and so on.

The below Sample code worked for me and might help someone.

import org.springframework.core.io.ByteArrayResource;
import org.springframework.core.io.Resource;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

@RestController
@RequestMapping("/app")
public class ImageResource {

    private static final String EXTENSION = ".jpg";
    private static final String SERVER_LOCATION = "/server/images";

    @RequestMapping(path = "/download", method = RequestMethod.GET)
    public ResponseEntity<Resource> download(@RequestParam("image") String image) throws IOException {
        File file = new File(SERVER_LOCATION + File.separator + image + EXTENSION);

        HttpHeaders header = new HttpHeaders();
        header.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=img.jpg");
        header.add("Cache-Control", "no-cache, no-store, must-revalidate");
        header.add("Pragma", "no-cache");
        header.add("Expires", "0");

        Path path = Paths.get(file.getAbsolutePath());
        ByteArrayResource resource = new ByteArrayResource(Files.readAllBytes(path));

        return ResponseEntity.ok()
                .headers(header)
                .contentLength(file.length())
                .contentType(MediaType.parseMediaType("application/octet-stream"))
                .body(resource);
    }

}

it is enough to call it this way:

<a href="home.php?date=<?= date('Y-m-d', strtotime('-1 day')) ?>" class="prev_day" title="Previous Day" ></a>
<a href="home.php?date=<?= date('Y-m-d', strtotime('+1 day')) ?>" class="next_day" title="Next Day" ></a>

Also see the documentation.

To undo the most recent commit I do this:

First:

git log

get the very latest SHA id to undo.

git revert SHA

That will create a new commit that does the exact opposite of your commit. Then you can push this new commit to bring your app to the state it was before, and your git history will show these changes accordingly.

This is good for an immediate redo of something you just committed, which I find is more often the case for me.

As Mike metioned, you can also do this:

git revert HEAD

<input type="checkbox" id="something" />

$("#something").click( function(){
   if( $(this).is(':checked') ) alert("checked");
});

Edit: Doing this will not catch when the checkbox changes for other reasons than a click, like using the keyboard. To avoid this problem, listen to changeinstead of click.

For checking/unchecking programmatically, take a look at Why isn't my checkbox change event triggered?

Handy if used in a common file - prints file name, line number and function of the caller:

import inspect
def getLineInfo():
    print(inspect.stack()[1][1],":",inspect.stack()[1][2],":",
          inspect.stack()[1][3])

esp is as you say it is, the top of the stack.

ebp is usually set to esp at the start of the function. Function parameters and local variables are accessed by adding and subtracting, respectively, a constant offset from ebp. All x86 calling conventions define ebp as being preserved across function calls. ebp itself actually points to the previous frame's base pointer, which enables stack walking in a debugger and viewing other frames local variables to work.

Most function prologs look something like:

push ebp      ; Preserve current frame pointer
mov ebp, esp  ; Create new frame pointer pointing to current stack top
sub esp, 20   ; allocate 20 bytes worth of locals on stack.

Then later in the function you may have code like (presuming both local variables are 4 bytes)

mov [ebp-4], eax    ; Store eax in first local
mov ebx, [ebp - 8]  ; Load ebx from second local

FPO or frame pointer omission optimization which you can enable will actually eliminate this and use ebp as another register and access locals directly off of esp, but this makes debugging a bit more difficult since the debugger can no longer directly access the stack frames of earlier function calls.

EDIT:

For your updated question, the missing two entries in the stack are:

var_C = dword ptr -0Ch
var_8 = dword ptr -8
var_4 = dword ptr -4
*savedFramePointer = dword ptr 0*
*return address = dword ptr 4*
hInstance = dword ptr  8h
PrevInstance = dword ptr  0C
hlpCmdLine = dword ptr  10h
nShowCmd = dword ptr  14h

This is because the flow of the function call is:

• Push parameters (hInstance, etc.)
• Call function, which pushes return address
• Push ebp
• Allocate space for locals

I had the same problem with Pool() in Python 3.6.3.

Error received: TypeError: can't pickle _thread.RLock objects

Let's say we want to add some number num_to_add to each element of some list num_list in parallel. The code is schematically like this:

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1 

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list)) 
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

    def run_parallel(self, num, shared_new_num_list):
        new_num = num + self.num_to_add # uses class parameter
        shared_new_num_list.append(new_num)

The problem here is that self in function run_parallel() can't be pickled as it is a class instance. Moving this parallelized function run_parallel() out of the class helped. But it's not the best solution as this function probably needs to use class parameters like self.num_to_add and then you have to pass it as an argument.

Solution:

def run_parallel(num, shared_new_num_list, to_add): # to_add is passed as an argument
    new_num = num + to_add
    shared_new_num_list.append(new_num)

class DataGenerator:
    def __init__(self, num_list, num_to_add)
        self.num_list = num_list # e.g. [4,2,5,7]
        self.num_to_add = num_to_add # e.g. 1

        self.run()

    def run(self):
        new_num_list = Manager().list()

        pool = Pool(processes=50)
        results = [pool.apply_async(run_parallel, (num, new_num_list, self.num_to_add)) # num_to_add is passed as an argument
                      for num in num_list]
        roots = [r.get() for r in results]
        pool.close()
        pool.terminate()
        pool.join()

Other suggestions above didn't help me.

In addition from the command prompt run SET.

This displayed the "LOGONSERVER" value which indicates the specific domain controller you are using (there can be more than one).

Then you got to that server's NetBios Share \Servername\SYSVOL\domain.local\scripts.

You can use strtotime:

$date = strtotime('2010-01-01 -1 year');

The strtotime function returns a unix timestamp, to get a formatted string you can use date:

echo date('Y-m-d', $date); // echoes '2009-01-01'

Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:

1. You should never send your model to the view => This is correct
2. If you create a ViewModel, and include the Model as member in the ViewModel, then you effectively sent your model to the View => this is BAD
3. Using dictionaries to send the options to the view => this not good style

So how can you create a better coupling?

I would use a tool like AutoMapper or ValueInjecter to map between ViewModel and Model. AutoMapper does seem to have the better syntax and feel to it, but the current version lacks a very severe topic: It is not able to perform the mapping from ViewModel to Model (under certain circumstances like flattening, etc., but this is off topic) So at present I prefer to use ValueInjecter.

So you create a ViewModel with the fields you need in the view. You add the SelectList items you need as lookups. And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist: You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList from the view to the controller.

  // StaffTypes is an IEnumerable<StaffType> from dbContext
  // viewModel is the viewModel initialized to copy content of Model Employee  
  // viewModel.StaffTypes is of type SelectList

  viewModel.StaffTypes =
    new SelectList(
        StaffTypes.OrderBy( item => item.Name )
        "StaffTypeID",
        "Type",
        viewModel.StaffTypeID
    );

In the view you just have to call

@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )

Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel. You then check for validation. If the validation fails, you have to remember to re-populate the viewModel.StaffTypes SelectList, because this item will be null on entering the post function. So I tend to have those population things separated into a function. You just call back return new View(viewModel) if anything is wrong. Validation errors found by MVC3 will automatically be shown in the view.

If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState to get info on that.

If the viewModel is valid you have to perform the next step:

If it is a create of a new item, you have to populate a model from the viewModel (best suited is ValueInjecter). Then you can add it to the EF collection of that type and commit changes.

If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel back to the model (again using ValueInjecter gets you do that very quick). After that you can SaveChanges and are done.

Feel free to ask if anything is unclear.

The other way to make your submodule to check out the branch is to go the .gitmodules file in the root folder and add the field branch in the module configuration as following:

branch = <branch-name-you-want-module-to-checkout>

My VPN connection was not enabled. I was trying all possible way to open up the Firwall and Ports until I realized, I am working from home and my VPN connection was down. But yes, Firewall and ssh configurations can be a reason.

If the error persists after doing what @Burhan Khalid said

Try this line: python manage.py migrate --run-syncdb

You could try changing the: SizeMode property of the PictureBox.

You could also set your image as the BackGroundImage of the PictureBox and try changing the BackGroundImageLayout to the correct mode.

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

here is my solution using c++ if brackets are matched then returns true if not then gives false

#include <iostream>
#include <stack>
#include <string.h>
using namespace std;

int matchbracket(string expr){
    stack<char> st;
    int i;
    char x;
    for(i=0;i<expr.length();i++){
        if(expr[i]=='('||expr[i]=='{'||expr[i]=='[')
          st.push(expr[i]);
          
        if(st.empty())
         return -1;
        switch(expr[i]){
            case ')' :
             x=expr[i];
             st.pop();
             if(x=='}'||x==']')
              return 0;
              break;
            
            case '}' :
             x=expr[i];
             st.pop();
             if(x==')'||x==']')
              return 0;
              break;
        
            case ']' :
            x=expr[i];
            st.pop();
            if(x==')'||x=='}')
             return 1;
             break;
        } 

    }
    return(st.empty());
}

int main()
{
 string expr;
 cin>>expr;
 
 if(matchbracket(expr)==1)
  cout<<"\nTRUE\n";
  else
  cout<<"\nFALSE\n";
}

Using --disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files switch?

Before using these commands be sure to end all running instances of Chrome.

On Windows:

chrome.exe --allow-file-access-from-files

On Mac:

open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files

Discussions of this "feature" of Chrome:

• https://bugs.chromium.org/p/chromium/issues/detail?id=37586,

This is possible.

//Create the select list item you want to add
SelectListItem selListItem = new SelectListItem() { Value = "null", Text = "Select One" };

//Create a list of select list items - this will be returned as your select list
List<SelectListItem> newList = new List<SelectListItem>();

//Add select list item to list of selectlistitems
newList.Add(selListItem);

//Return the list of selectlistitems as a selectlist
return new SelectList(newList, "Value", "Text", null);

I believe a simple cast can work

int ascii = (int) "A"

$_POST is an array in itsself you don't need to make an array out of it. What you did is nest the $_POST array inside a new array. This is why you print Array. Change it to:

foreach ($_POST as $key => $value) {

  echo "<p>".$key."</p>";
  echo "<p>".$value."</p>";
  echo "<hr />";

} 

Using Linq to find the object you can do:

var obj = myList.FirstOrDefault(x => x.MyProperty == myValue);
if (obj != null) obj.OtherProperty = newValue;

But in this case you might want to save the List into a Dictionary and use this instead:

// ... define after getting the List/Enumerable/whatever
var dict = myList.ToDictionary(x => x.MyProperty);
// ... somewhere in code
MyObject found;
if (dict.TryGetValue(myValue, out found)) found.OtherProperty = newValue;

You can always use STATUS command to get to know Current database & Current User

You can use Jquery's on method and listen for the scroll event.

Try this

var url = "http://www.exmple.com/234234234"
var res = url.split("/").pop();
alert(res);

If I read the specification correctly, no.

You can match on an element, the name of an attribute in the element, and the value of a named attribute in an element. I don't see anything for matching content within an element, though.

Installing the "security" package extras for requests solved for me:

sudo apt-get install libffi-dev
sudo pip install -U requests[security]

There is another scenario where this issue reproduces (as in my case). When THE CLIENT REQUEST doesn't contain the right extension on the url, the controller can't identify the desired result format.

For example: the controller is set to respond_to :json (as a single option, without a HTML response)- while the client call is set to /reservations instead of /reservations.json.

Bottom line, change the client call to /reservations.json.

The point about generics is to give compile-time type safety - which means that types need to be known at compile-time.

You can call generic methods with types only known at execution time, but you have to use reflection:

// For non-public methods, you'll need to specify binding flags too
MethodInfo method = GetType().GetMethod("DoesEntityExist")
                             .MakeGenericMethod(new Type[] { t });
method.Invoke(this, new object[] { entityGuid, transaction });

Ick.

Can you make your calling method generic instead, and pass in your type parameter as the type argument, pushing the decision one level higher up the stack?

If you could give us more information about what you're doing, that would help. Sometimes you may need to use reflection as above, but if you pick the right point to do it, you can make sure you only need to do it once, and let everything below that point use the type parameter in a normal way.

If I understand correctly you want to change the CSS style of an element by clicking an item in a ul list. Am I right?

HTML:

<div class="results" style="background-color:Red;">
</div>

 <ul class="colors-list">
     <li>Red</li>
     <li>Blue</li>
     <li>#ffee99</li>
 </ul>

jquery

$('.colors-list li').click(function(e){
    var color = $(this).text();
    $('.results').css('background-color',color);
});

Note that jquery can use addClass, removeClass and toggleClass if you want to use classes rather than inline styling. This means that you can do something like that:

$('.results').addClass('selected');

And define the 'selected' styling in the CSS.

Working example: http://jsfiddle.net/uuJmP/

SELECT COUNT(1)
FROM FB
WHERE
    Dte BETWEEN CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(DATEADD(month, -1, GETDATE())) AS VARCHAR(2)) + '-20 00:00:00'
        AND CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(GETDATE()) AS VARCHAR(2)) + '-20 00:00:00'

You can use flexbox for this.

ul {
    display: flex;
    align-items: center;
}

A detailed explanation of how to use flexbox can be found here.

Use something like this:

var myVar = null;

And then inside your function:

myVar = fldID;

And then:

setTimeout(setFocus,1000)

And then:

function setFocus(){ document.getElementById(fldID).focus(); }

Final code:

<html>
<head>
    <script type="text/javascript">
        function somefunction(){
            var myVar = null;

            myVar = document.getElementById('myInput');

            if(myVar.value=='')
                setTimeout(setFocusOnJobTitle,1000);
            else
                myVar.value='Success';
        }
        function setFocusOnJobTitle(){
            document.getElementById('myInput').focus();
        }
    </script>
</head>
<body>
<label id="jobTitleId" for="myInput">Job Title</label>
<input id="myInput" onblur="somefunction();"></input>
</body>
</html>

I apply a short solution that is suitable even for fragments of dialogue.

            //The listener of a drawableEnd button for clear a TextInputEditText
            textValue.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if(event.getAction() == MotionEvent.ACTION_UP) {
                        final TextView textView = (TextView)v;
                        if(event.getX() >= textView.getWidth() - textView.getCompoundPaddingEnd()) {
                            textView.setText(""); //Clear a view, example: EditText or TextView
                            return true;
                        }
                    }
                    return false;
                }
            });

php artisan serve 

this command get the env contents for the first time and if you update .env file need to restart it.

in my case my username and dbname is valid and php artisan migrate worked

but need to cntrl+c , to cancel php artisan serve , and run it again

php artisan serve

I already found the solution to this problem which I forgot to post here.

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Test.class })
public class SampleTest {

@Mock
Person person;

@Test
public void testPrintName() throws Exception {
    PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);
    Test test= new Test();
    test.testMethod();
    }
}

Key points to this solution are:

1. Running my test cases with PowerMockRunner: @RunWith(PowerMockRunner.class)

2. Instruct Powermock to prepare Test.class for manipulation of private fields: @PrepareForTest({ Test.class })

3. And finally mock the constructor for Person class:

   PowerMockito.mockStatic(Person.class); PowerMockito.whenNew(Person.class).withNoArguments().thenReturn(person);

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

For me something was wrong in the PATH enviroment variable. I removed all path related to npm and added at the start of PATH this folder:

c:\Users\<your-user-name>\AppData\Roaming\npm\

Make sure you have ; between paths.

Make sure that you actually save the file as UTF-8, alternatively use HTML entities (&#nnn;) for the special characters.

It will render html element using creating SVG images.

Line width in ggplot2 can be changed with argument lwd= in geom_line().

geom_line(aes(x=..., y=..., color=...), lwd=1.5)

Maybe you want to use twill. It's quite easy to use and should be able to do what you want.

It will look like the following:

from twill.commands import *
go('http://example.org')

fv("1", "email-email", "blabla.com")
fv("1", "password-clear", "testpass")

submit('0')

You can use showforms() to list all forms once you used go… to browse to the site you want to login. Just try it from the python interpreter.

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

mysql --help | grep /my.cnf | xargs ls

will tell you where my.cnf is located on Mac/Linux

ls: cannot access '/etc/my.cnf': No such file or directory
ls: cannot access '~/.my.cnf': No such file or directory
 /etc/mysql/my.cnf

In this case, it is in /etc/mysql/my.cnf

ls: /etc/my.cnf: No such file or directory
ls: /etc/mysql/my.cnf: No such file or directory
ls: ~/.my.cnf: No such file or directory
/usr/local/etc/my.cnf

In this case, it is in /usr/local/etc/my.cnf

Try this:

public void paint (Graphics g) {    
    Rectangle r = new Rectangle(xPos,yPos,width,height);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());  
}

[edit]

// With explicit casting
public void paint (Graphics g) {    
        Rectangle r = new Rectangle(xPos, yPos, width, height);
        g.fillRect(
           (int)r.getX(),
           (int)r.getY(),
           (int)r.getWidth(),
           (int)r.getHeight()
        );  
    }

try CAST function in MySQL:

mysql_query("INSERT INTO data_table (title, date_of_event)
VALUES('". $_POST['post_title'] ."',
CAST('". $date ."' AS DATE))") or die(mysql_error()); 

Well, you would typically use

System.out.println("print something");

which doesn't require any imports. However, since out is a static field inside of System, you could write use a static import like this:

import static java.lang.System.*;

class Test {
    public static void main(String[] args) {
        out.println("print something");
    }
}

Take a look at this link. Typically you would only do this if you are using a lot of static methods from a particular class, like I use it all the time for junit asserts, and easymock.

env VAR=value myScript args ...

<script  type="text/javascript">
    $(document).ready(function () {
        $("#txtDate").datepicker({ dateFormat: 'yy/mm/dd' }).datepicker("setDate", "0");
        $("#txtDate2").datepicker({ dateFormat: 'yy/mm/dd',  }).datepicker("setDate", new Date().getDay+15); });                       </script>   

The idiomatic way is to use a class, which can have attributes. If you need instances to not be separate, use a singleton.

There are a number of ways you could fake or munge "static" variables into Python (one not mentioned so far is to have a mutable default argument), but this is not the Pythonic, idiomatic way to do it. Just use a class.

Or possibly a generator, if your usage pattern fits.

This will give the correct (custom) filter when the file dialog is showing:

<input type="file" accept=".jpg, .png, .jpeg, .gif, .bmp, .tif, .tiff|image/*">

For a more detailed answer on creating your own colormaps, I highly suggest visiting this page

If that answer is too much work, you can quickly make your own list of colors and pass them to the color parameter. All the colormaps are in the cm matplotlib module. Let's get a list of 30 RGB (plus alpha) color values from the reversed inferno colormap. To do so, first get the colormap and then pass it a sequence of values between 0 and 1. Here, we use np.linspace to create 30 equally-spaced values between .4 and .8 that represent that portion of the colormap.

from matplotlib import cm
color = cm.inferno_r(np.linspace(.4, .8, 30))
color

array([[ 0.865006,  0.316822,  0.226055,  1.      ],
       [ 0.851384,  0.30226 ,  0.239636,  1.      ],
       [ 0.832299,  0.283913,  0.257383,  1.      ],
       [ 0.817341,  0.270954,  0.27039 ,  1.      ],
       [ 0.796607,  0.254728,  0.287264,  1.      ],
       [ 0.775059,  0.239667,  0.303526,  1.      ],
       [ 0.758422,  0.229097,  0.315266,  1.      ],
       [ 0.735683,  0.215906,  0.330245,  1.      ],
       .....

Then we can use this to plot, using the data from the original post:

import random
x = [{i: random.randint(1, 5)} for i in range(30)]
df = pd.DataFrame(x)
df.plot(kind='bar', stacked=True, color=color, legend=False, figsize=(12, 4))

        print request.body

It switches back because by default, when you click a link, it follows the link and loads the page. In your case, you don't want that. You can prevent it either by doing e.preventDefault(); (like Neal mentioned) or by returning false :

$(function() {
 $('.menulink').click(function(){
   $("#bg").attr('src',"img/picture1.jpg");
   return false;
 });
});

Interesting question on the differences between prevent default and return false.

In this case, return false will work just fine because the event doesn't need to be propagated.

Some context additional about basic authentication, it consists in a header which contains the key/value pair:

Authorization: Basic Z2VybWFuOmdlcm1hbg==

where "Authorization" is the headers key, and the headers value has a string ( "Basic" word plus blank space) concatenated to "Z2VybWFuOmdlcm1hbg==", which are the user and password in base 64 joint by double dot

String name = "username";
String password = "secret";
String authString = name + ":" + password;
String authStringEnc = new BASE64Encoder().encode(authString.getBytes());
...
objectXXX.header("Authorization", "Basic " + authStringEnc);

Double quotes can be achieved using VBA in one of two ways

First one is often the best

"...text..." & Chr(34) & "...text..."

Or the second one, which is more literal

"...text..." & """" & "...text..."

From the manual:

If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns FALSE or emits PDOException (depending on error handling).

The prepare statement likely caused an error because the db would be unable to prepare the statement. Try testing for an error immediately after you prepare your query and before you execute it.

$qry = '
    INSERT INTO non-existant-table (id, score) 
    SELECT id, 40 
    FROM another-non-existant-table
    WHERE description LIKE "%:search_string%"
    AND available = "yes"
    ON DUPLICATE KEY UPDATE score = score + 40
';
$sth = $this->pdo->prepare($qry);
print_r($this->pdo->errorInfo());

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

I was able to solve the problem running MS SQL Management Studio as ADMINISTRATOR.

The ModelState property on the controller is actually a ModelStateDictionary object. You can iterate through the keys on the dictionary and use the IsValidField method to check if that particular field is valid.

Another way to do it in Postgres would be to use the idx function.

SELECT *
FROM comments
ORDER BY idx(array[1,3,2,4], comments.id)

Don't forget to create the idx function first, as described here: http://wiki.postgresql.org/wiki/Array_Index

I'm not really sure, I guess it depends on the task: how often to run, how much complicated and how much direct communication with the rails project is needed etc. I guess if there was just "One Best Way" to do something, there wouldn't be so many different ways to do it.

At my last job in a Rails project, we needed to make a batch invitation mailer (survey invitations, not spamming) which should send the planned mails whenever the server had time. I think we were going to use daemon tools to run the rake tasks I had created.

Unfortunately, our company had some money problems and was "bought" by the main rival so the project was never completed, so I don't know what we would eventually have used.

You can chain methods off the returned object, so you can immediately close the file you just opened in a single statement.

File.Open("filename", FileMode.Create).Close();

you can use asctime() function of time.h to get a string simply .

time_t _tm =time(NULL );

struct tm * curtime = localtime ( &_tm );
cout<<"The current date/time is:"<<asctime(curtime);

Sample output:

The current date/time is:Fri Oct 16 13:37:30 2015

I know this question was asked a long time ago, but I wanted to provide another way to do this that I found useful for an issue I just worked on:

lshw -c memory

lshw

lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work).

Just need to add version of which you want

upgrade or downgrade

npm install -g npm@version

Example if you want to downgrade from npm 5.6.0 to 4.6.1 then,

npm install -g [email protected]

It is tested on linux

Don't forget. if you are trying to hover around an image, you have to put it around a container. css:

.brand:hover + .brand-sales {
    display: block;
}

.brand-sales {
    display: none;
}

If you hover on this:

<span className="brand">
   <img src="https://murmure.me/wp-content/uploads/2017/10/nike-square-1900x1900.jpg" 
     alt"some image class="product-card-place-logo"/>
</span>

This will show:

<div class="product-card-sales-container brand-sales">
    <div class="product-card-">Message from the business goes here. They can talk alot or not</div>
</div>

Is an array variable really necessary?

I ask because I originally landed here wanting to add an array as a MySQL table variable. I was relatively new to database design and trying to think of how I'd do it in a typical programming language fashion.

But databases are different. I thought I wanted an array as a variable, but it turns out that's just not a common MySQL database practice.

Standard Practice

The alternative solution to arrays is to add an additional table, and then reference your original table with a foreign key.

As an example, let's imagine an application that keeps track of all the items every person in a household wants to buy at the store.

The commands for creating the table I originally envisioned would have looked something like this:

#doesn't work
CREATE TABLE Person(
  name VARCHAR(50) PRIMARY KEY
  buy_list ARRAY
);

I think I envisioned buy_list to be a comma-separated string of items or something like that.

But MySQL doesn't have an array type field, so I really needed something like this:

CREATE TABLE Person(
  name VARCHAR(50) PRIMARY KEY
);
CREATE TABLE BuyList(
  person VARCHAR(50),
  item VARCHAR(50),
  PRIMARY KEY (person, item),
  CONSTRAINT fk_person FOREIGN KEY (person) REFERENCES Person(name)
);

Here we define a constraint named fk_person. It says that the 'person' field in BuyList is a foreign key. In other words, it's a primary key in another table, specifically the 'name' field in the Person table, which is what REFERENCES denotes.

We also defined the combination of person and item to be the primary key, but technically that's not necessary.

Finally, if you want to get all the items on a person's list, you can run this query:

SELECT item FROM BuyList WHERE person='John';

This gives you all the items on John's list. No arrays necessary!

I suggest use the common way of import.

First I will explain the way it called "relative import" maybe this way cause of some error

Second I will explain the common way of import.

FIRST:

In go version >= 1.12 there is some new tips about import file and somethings changed.

1- You should put your file in another folder for example I create a file in "model" folder and the file's name is "example.go"

2- You have to use uppercase when you want to import a file!

3- Use Uppercase for variables, structures and functions that you want to import in another files

Notice: There is no way to import the main.go in another file.

file directory is:

root
|_____main.go
|_____model
          |_____example.go

this is a example.go:

package model

import (
    "time"
)

var StartTime = time.Now()

and this is main.go you should use uppercase when you want to import a file. "Mod" started with uppercase

package main

import (
    Mod "./model"
    "fmt"
)

func main() {
    fmt.Println(Mod.StartTime)
}

NOTE!!!

NOTE: I don't recommend this this type of import!

SECOND:

(normal import)

the better way import file is:

your structure should be like this:

root
|_____github.com
         |_________Your-account-name-in-github
         |                |__________Your-project-name
         |                                |________main.go
         |                                |________handlers
         |                                |________models
         |               
         |_________gorilla
                         |__________sessions

and this is a example:

package main

import (
    "github.com/gorilla/sessions"
)

func main(){
     //you can use sessions here
}

so you can import "github.com/gorilla/sessions" in every where that you want...just import it.

In the manual (https://angular.io/guide/http) I read: The HttpHeaders class is immutable, so every set() returns a new instance and applies the changes.

The following code works for me with angular-4:

 return this.http.get(url, {headers: new HttpHeaders().set('UserEmail', email ) });

You can use below command if you want to print entire line and file name if the occurrence of particular word in current directory you are searching.

grep -m 1 -r "Not caching" * | head -1

If u want to add Hello world at the end of each line:

:%s/$/HelloWorld/

If you want to do this for specific number of line say, from 20 to 30 use:

:20,30s/$/HelloWorld/

If u want to do this at start of each line then use:

:20,30s/^/HelloWorld/

The Following command displays extra informations

curl -X POST http://httpbin.org/post -v > /dev/null

You can ask server to send just HEAD, instead of full response

curl -X HEAD -I http://httpbin.org/

Note: In some cases, server may send different headers for POST and HEAD. But in almost all cases headers are same.

I just came up with this very simple method of clearing an entire sheet.

Sub ClearThisSheet()

ActiveSheet.UsedRange.ClearContents

End Sub

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

assert_has_calls is another approach to this problem.

From the docs:

assert_has_calls (calls, any_order=False)

assert the mock has been called with the specified calls. The mock_calls list is checked for the calls.

If any_order is False (the default) then the calls must be sequential. There can be extra calls before or after the specified calls.

If any_order is True then the calls can be in any order, but they must all appear in mock_calls.

Example:

>>> from unittest.mock import call, Mock
>>> mock = Mock(return_value=None)
>>> mock(1)
>>> mock(2)
>>> mock(3)
>>> mock(4)
>>> calls = [call(2), call(3)]
>>> mock.assert_has_calls(calls)
>>> calls = [call(4), call(2), call(3)]
>>> mock.assert_has_calls(calls, any_order=True)

Source: https://docs.python.org/3/library/unittest.mock.html#unittest.mock.Mock.assert_has_calls

I had a problem with go get using private repository on gitlab from our company. I lost a few minutes trying to find a solution. And I did find this one:

1. You need to get a private token at:
   https://gitlab.mycompany.com/profile/account

2. Configure you git to add extra header with your private token:

   $ git config --global http.extraheader "PRIVATE-TOKEN: YOUR_PRIVATE_TOKEN
   

3. Configure your git to convert requests from http to ssh:

   $ git config --global url."[email protected]:".insteadOf "https://gitlab.mycompany.com/"
   

4. Finally you can use your go get normally:

   $ go get gitlab.com/company/private_repo
   

If you just want to filter everything other than the numbers out, the easiest is to use filter_var:

$str = 'In My Cart : 11 items';
$int = (int) filter_var($str, FILTER_SANITIZE_NUMBER_INT);

All the languages you've mentioned are Turing Complete, so in theory there is nothing one can do and another can't. In practice of course, there are differences, especially in productivity and efficiency. Compared to C, C++ and Java, which are static typed, Python is a dynamic language and can help you write the same code in significantly fewer lines. Python has a moto "batteries included", which means that the standard library offers all the things needed to build a complex application. Other languages would need external libraries for this. On top of this, since Python is an old and mature language (older than Java), many external libraries (for game development and scientific calculations just to mention a few) have been evolved. So Python can be used to program desktop applications and in fact in some cases more efficiently than other traditional languages.

Python is also a scripting language. This means that you can easily and quickly write scripts and simple tests with it.

More recently python is also used for web frameworks. Since there is a big code base and many python programmers, this was a logical thing to do. These web frameworks follow the practice mainly introduced by Ruby on Rails.

I had to struggle to find an answer, I was very new to iPython environment.

This will work

If your iPython session looks like this

In [1] : import numpy as np
....
In [135]: counter=collections.Counter(mapusercluster[3])
In [136]: counter
Out[136]: Counter({2: 700, 0: 351, 1: 233})

You want to save lines from 1 till 135 then on the same ipython session use this command

In [137]: %save test.py 1-135

This will save all your python statements in test.py file in your current directory ( where you initiated the ipython).

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

In the above example

int a = 5,i;

i=++a + ++a + a++;        //Ans: i = 6 + 7 + 7 = 20 then a = 8 

i=a++ + ++a + ++a;        //Ans: i = 8 + 10 + 11 = 29 then a = 11

a=++a + ++a + a++;        //Ans: a = 12 + 13 + 13 = 38

System.out.println(a);    //Ans: a = 38

System.out.println(i);    //Ans: i = 29

webpack.config.js:

const webpack = require("webpack");

module.exports = {
  entry: {
    "bundle": "./entry.js",
    "bundle.min": "./entry.js",
  },
  devtool: "source-map",
  output: {
    path: "./dist",
    filename: "[name].js"
  },
  plugins: [
    new webpack.optimize.UglifyJsPlugin({
      include: /\.min\.js$/,
      minimize: true
    })
  ]
};

Since Webpack 4, webpack.optimize.UglifyJsPlugin has been deprecated and its use results in error:

webpack.optimize.UglifyJsPlugin has been removed, please use config.optimization.minimize instead

As the manual explains, the plugin can be replaced with minimize option. Custom configuration can be provided to the plugin by specifying UglifyJsPlugin instance:

const webpack = require("webpack");
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');

module.exports = {
  // ...
  optimization: {
    minimize: true,
    minimizer: [new UglifyJsPlugin({
      include: /\.min\.js$/
    })]
  }
};

This does the job for a simple setup. A more effective solution is to use Gulp together with Webpack and do the same thing in one pass.

Have you read this? How do I create an AUTOINCREMENT field.

INSERT INTO people
VALUES (NULL, "John", "Smith");

@m59 Directives will work for ng-bind-html you just need to wait for $viewContentLoaded to finish

app.directive('targetBlank', function($timeout) {
  return function($scope, element) {
    $scope.initializeTarget = function() {
      return $scope.$on('$viewContentLoaded', $timeout(function() {
        var elems;
        elems = element.prop('tagName') === 'A' ? element : element.find('a');
        elems.attr('target', '_blank');
      }));
    };
    return $scope.initializeTarget();

  };
});

You could use a nested Any() for this check which is available on any Enumerable:

bool hasMatch = myStrings.Any(x => parameters.Any(y => y.source == x));

Faster performing on larger collections would be to project parameters to source and then use Intersect which internally uses a HashSet<T> so instead of O(n^2) for the first approach (the equivalent of two nested loops) you can do the check in O(n) :

bool hasMatch = parameters.Select(x => x.source)
                          .Intersect(myStrings)
                          .Any(); 

Also as a side comment you should capitalize your class names and property names to conform with the C# style guidelines.

Try this Using the substring(int start, int end); method

String myLongString = "abcdefghij";
if (myLongString .length() >= 10)
String shortStr = myLongString.substring(0, 5)+ "...";

this will return abcde.

java.exe is the console app while javaw.exe is windows app (console-less). You can't have Console with javaw.exe.

What you exactly wan't to do ?. To change Datatype of column you can simple use alter command as

ALTER TABLE table_name ALTER COLUMN LoginDate DateTime;

But remember there should valid Date only in this column however data-type is nvarchar.

If you wan't to convert data type while fetching data then you can use CONVERT function as,

CONVERT(data_type(length),expression,style)

eg:

SELECT CONVERT(DateTime, loginDate, 6)

This will return 29 AUG 13. For details about CONVERT function you can visit ,

http://www.w3schools.com/sql/func_convert.asp.

Remember, Always use DataTime data type for DateTime column.

Thank You

Here is a simple method to read the text file from the raw folder:

public static String readTextFile(Context context,@RawRes int id){
    InputStream inputStream = context.getResources().openRawResource(id);
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

    byte buffer[] = new byte[1024];
    int size;
    try {
        while ((size = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, size);
        }
        outputStream.close();
        inputStream.close();
    } catch (IOException e) {

    }
    return outputStream.toString();
}

Here is a function that calculates the current position of an element within the viewport:

/**
 * Calculates the position of a given element within the viewport
 *
 * @param {string} obj jQuery object of the dom element to be monitored
 * @return {array} An array containing both X and Y positions as a number
 * ranging from 0 (under/right of viewport) to 1 (above/left of viewport)
 */
function visibility(obj) {
    var winw = jQuery(window).width(), winh = jQuery(window).height(),
        elw = obj.width(), elh = obj.height(),
        o = obj[0].getBoundingClientRect(),
        x1 = o.left - winw, x2 = o.left + elw,
        y1 = o.top - winh, y2 = o.top + elh;

    return [
        Math.max(0, Math.min((0 - x1) / (x2 - x1), 1)),
        Math.max(0, Math.min((0 - y1) / (y2 - y1), 1))
    ];
}

The return values are calculated like this:

Usage:

visibility($('#example'));  // returns [0.3742887830933581, 0.6103752759381899]
