If you're using the iframe and postMessage solution just for this particular problem, I think it might be less work (both code-wise and computation-wise) to just store the data in a subdomain-less cookie and, if it's not already in localStorage on load, grab it from the cookie.

Pros:

• Doesn't need the extra iframe and postMessage set up.

Cons:

• Will make the data available across all subdomains (not just www) so if you don't trust all the subdomains it may not work for you.
• Will send the data to the server on each request. Not great, but depending on your scenario, maybe still less work than the iframe/postMessage solution.
• If you're doing this, why not just use the cookies directly? Depends on your context.
• 4K max cookie size, total across all cookies for the domain (Thanks to Blake for pointing this out in comments)

I agree with other commenters though, this seems like it should be a specifiable option for localStorage so work-arounds aren't required.

Using .attr method

.attr(attribute,value); // syntax

.attr("required", true);
// required="required"

.attr("required", false);
// 

Using .prop

.prop(property,value) // syntax

.prop("required", true);
// required=""

.prop("required", false);

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

I solved this problem temporary by disabling the dfs permission.By adding below property code to conf/hdfs-site.xml

<property>
  <name>dfs.permissions</name>
  <value>false</value>
</property>

This is turning out to be a surprisingly tricky question.

I would recommend using Array.Reverse for most cases as it is coded natively and it is very simple to maintain and understand.

It seems to outperform StringBuilder in all the cases I tested.

public string Reverse(string text)
{
   if (text == null) return null;

   // this was posted by petebob as well 
   char[] array = text.ToCharArray();
   Array.Reverse(array);
   return new String(array);
}

There is a second approach that can be faster for certain string lengths which uses Xor.

    public static string ReverseXor(string s)
    {
        if (s == null) return null;
        char[] charArray = s.ToCharArray();
        int len = s.Length - 1;

        for (int i = 0; i < len; i++, len--)
        {
            charArray[i] ^= charArray[len];
            charArray[len] ^= charArray[i];
            charArray[i] ^= charArray[len];
        }

        return new string(charArray);
    }

Note If you want to support the full Unicode UTF16 charset read this. And use the implementation there instead. It can be further optimized by using one of the above algorithms and running through the string to clean it up after the chars are reversed.

Here is a performance comparison between the StringBuilder, Array.Reverse and Xor method.

Keep the h2 at the top, then pull-left on the p and pull-right on the login-box

<div class='container'>
  <div class='hero-unit'>

    <h2>Welcome</h2>

    <div class="pull-left">
      <p>Please log in</p>
    </div>

    <div id='login-box' class='pull-right control-group'>
        <div class='clearfix'>
            <input type='text' placeholder='Username' />
        </div>
        <div class='clearfix'>
            <input type='password' placeholder='Password' />
        </div>
        <button type='button' class='btn btn-primary'>Log in</button>
    </div>

    <div class="clearfix"></div>

  </div>
</div>

the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

Also you can use ilmergertool at codeplex with GUI interface.

When this type of problem occurs simply delete previous path setting and add new path in Environment variable.

new path name JAVA_HOME path "Your computer path" without \bin

and also edit path variable with \bin path.

netbeans will working fine whatever the version is.either jdk 9 or upper version.

I can think of a one liner like this to run

ping -c 1 127.0.0.1 &> /dev/null && echo success || echo fail

Replace 127.0.0.1 with IP or hostname, replace echo commands with what needs to be done in either case.

Code above will succeed, maybe try with an IP or hostname you know that is not accessible.

Like this:

ping -c 1 google.com &> /dev/null && echo success || echo fail

and this

ping -c 1 lolcatz.ninja &> /dev/null && echo success || echo fail

A session cookie is just a normal cookie without an expiration date. Those are handled by the browser to be valid until the window is closed or program is quit.

But if the cookie is a httpOnly cookie (a cookie with the httpOnly parameter set), you cannot read, change or delete it from outside of HTTP (meaning it must be changed on the server).

I see that this question is already old but still...

We made a sipmle library at our company for achieving what is desired - An interactive info window with views and everything. You can check it out on github.

I hope it helps :)

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

Perform multiple queries or use embedded documents or look at "database references".

I have reformatted your code.

The error was situated in this line :

printf("%d", (**c));

To fix it, change to :

printf("%d", (*c));

The * retrieves the value from an address. The ** retrieves the value (an address in this case) of an other value from an address.

In addition, the () was optional.

#include <stdio.h>

int main(void)
{
    int b = 10; 
    int *a = NULL;
    int *c = NULL;

    a = &b;
    c = &a;

    printf("%d", *c);

    return 0;
} 

EDIT :

The line :

c = &a;

must be replaced by :

c = a;

It means that the value of the pointer 'c' equals the value of the pointer 'a'. So, 'c' and 'a' points to the same address ('b'). The output is :

10

EDIT 2:

If you want to use a double * :

#include <stdio.h>

int main(void)
{
    int b = 10; 
    int *a = NULL;
    int **c = NULL;

    a = &b;
    c = &a;

    printf("%d", **c);

    return 0;
} 

Output:

10

std::string the_string(c_string);
if(the_string.size() > max_length)
    the_string.resize(max_length);

try this

the solution is, work with callbacks like this

$(function() {

    var jForm = $('form[name=form]');
    var jPWField = $('#employee_password');

    function getCheckedState() {
        return jForm.data('checked_state');
    };

    function setChecked(s) {
        jForm.data('checked_state', s);
    };


    jPWField.change(function() {
        //reset checked thing
        setChecked(null);
    }).trigger('change');

    jForm.submit(function(){
        switch(getCheckedState()) {
            case 'valid':
                return true;
            case 'invalid':
                //invalid, don submit
                return false;
            default:
                //make your check
                var password = $.trim(jPWField.val());

                $.ajax({
                    type: "POST",
                    async: "false",
                    url: "checkpass.php",
                    data: {
                        "password": $.trim(jPWField.val);
                    }
                    success: function(html) {
                        var arr=$.parseJSON(html);
                        setChecked(arr == "Successful" ? 'valid': 'invalid');
                        //submit again
                        jForm.submit();
                    }
                    });
                return false;
        }

    });
 });

Use --build-arg with each argument.

If you are passing two argument then add --build-arg with each argument like:

docker build \
-t essearch/ess-elasticsearch:1.7.6 \
--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .

Go to your project path on CMD(command Prompt) and execute the following command:-

set FLASK_APP=ABC.py

SET FLASK_ENV=development

flask run -h [yourIP] -p 8080

you will get following o/p on CMD:-

• Serving Flask app "expirement.py" (lazy loading)
  • Environment: development
  • Debug mode: on
  • Restarting with stat
  • Debugger is active!
  • Debugger PIN: 199-519-700
  • Running on http://[yourIP]:8080/ (Press CTRL+C to quit)

Now you can access your flask app on another machine using http://[yourIP]:8080/ url

Expanding on Donut's answer and the other answers here, you can get even better results by using a generator comprehension instead of a list comprehension, and by using a set data structure (since the in operator is O(n) on a list but O(1) on a set).

So here's a function that would work for you:

def filter_list(full_list, excludes):
    s = set(excludes)
    return (x for x in full_list if x not in s)

The result will be an iterable that will lazily fetch the filtered list. If you need a real list object (e.g. if you need to do a len() on the result), then you can easily build a list like so:

filtered_list = list(filter_list(full_list, excludes))

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

Using the Regex methods in .NET you should be able to match any non-numeric digit using \D, like so:

phoneNumber  = Regex.Replace(phoneNumber, "\\D", String.Empty);

How reliable is your format? If the seperator is always exactly ': ', the following works. If not, a comparatively simple regex should do the job.

As long as you're working with fairly simple variable types, Python's eval function makes persisting variables to files surprisingly easy.

(The below gives you a dictionary, btw, which you mentioned was one of your prefered solutions).

def read_config(filename):
    f = open(filename)
    config_dict = {}
    for lines in f:
        items = lines.split(': ', 1)
        config_dict[items[0]] = eval(items[1])
    return config_dict

You are opening the file as "w", which stands for writable.

Using "w" you won't be able to read the file. Use the following instead:

file = open("File.txt","r")

Additionally, here are the other options:

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

Not sure if this is official but this worked for me in typescript 2.7.1:

class Item {
   configs: Map<string, string>;
   constructor () {
     this.configs = new Map();
   }
}

In simple Map<keyType, valueType>

It is also possible to use Spring Data JDBC repository, which is a community project built on top of Spring Data Commons to access to databases with raw SQL, without using JPA.

It is less powerful than Spring Data JPA, but if you want lightweight solution for simple projects without using a an ORM like Hibernate, that a solution worth to try.

I struggled with the same problem. I have stored dates in SQL Server with format 'YYYY-MM-DD HH:NN:SS' for about 20 years, but today that was not able anymore from a C# solution using OleDbCommand and a UPDATE query.

The solution to my problem was to remove the hyphen - in the format, so the resulting formatting is now 'YYYYMMDD HH:MM:SS'. I have no idea why my previous formatting not works anymore, but I suspect there is something to do with some Windows updates for ADO.

Java 8 style

   JSONArray data = jsonObject.getJSONArray("some-node");

   List<JSONObject> list = StreamSupport.stream(data.spliterator(), false)
                .map(e -> (JSONObject)e)
                .collect(Collectors.toList());

If anyone finds their way here with the same problem I was having, my problem was that I was missing the <dependencyManagement> tags around dependencies I had copied from the child pom.

Remember: Javascript functions are CASE SENSITIVE.

I had a case where I'm pretty sure that my code would run smoothly. But still, got an error and I checked the Javascript console of Google Chrome to check what it is.

My error line is

opt.SetAttribute("value",values[a]);

And got the same error message:

Uncaught TypeError: undefined is not a function

Nothing seems wrong with the code above but it was not running. I troubleshoot for almost an hour and then compared it with my other running code. My error is that it was set to SetAttribute, which should be setAttribute.

Use a pattern along these lines:

function getValue(file) {
  return lookupValue(file);
}

getValue('myFile.txt').then(function(res) {
  // do whatever with res here
});

(although this is a bit redundant, I'm sure your actual code is more complicated)

I use XCOPY with the following parameters for copying .NET assemblies:

/D /Y /R /H 

/D:m-d-y - Copies files changed on or after the specified date. If no date is given, copies only those files whose source time is newer than the destination time.

/Y - Suppresses prompting to confirm you want to overwrite an existing destination file.

/R - Overwrites read-only files.

/H - Copies hidden and system files also.

The nested class doesn't know about the outer class, and protected doesn't help. You'll have to pass some actual reference to objects of the nested class type. You could store a foo*, but perhaps a reference to the integer is enough:

class Outer
{
    int n;

public:
    class Inner
    {
        int & a;
    public:
        Inner(int & b) : a(b) { }
        int & get() { return a; }
    };

    // ...  for example:

    Inner inn;
    Outer() : inn(n) { }
};

Now you can instantiate inner classes like Inner i(n); and call i.get().

First of all you need to differentiate between the MySQL as Server, MySQL as Client and the Ruby bindings to MySQL.

I'm not familiar with Mac, but for *nix OS you need to install MySQL through your package manager. To get the Ruby bindings installed with

gem install mysql

you need the development headers of ruby (in Ubuntu it is the package ruby-dev) and the development headers of the MySQL-Client (currently libmysqlclient16-dev in Ubuntu). I don't know if they are named different on Mac, but after you got those installed the Ruby bindings should install without any error.

Many of these answers are simply wrong for the general case, others are unnecessarily complicated if they in fact even work. The jQuery .before and .after methods do most of what you want to do, but you need a 3rd element the way many swap algorithms work. It's pretty simple - make a temporary DOM element as a placeholder while you move things around. There is no need to look at parents or siblings, and certainly no need to clone...

$.fn.swapWith = function(that) {
  var $this = this;
  var $that = $(that);

  // create temporary placeholder
  var $temp = $("<div>");

  // 3-step swap
  $this.before($temp);
  $that.before($this);
  $temp.after($that).remove();

  return $this;
}

1) put the temporary div temp before this

2) move this before that

3) move that after temp

3b) remove temp

Then simply

$(selectorA).swapWith(selectorB);

DEMO: http://codepen.io/anon/pen/akYajE

For add environment variable please add \ after bin like below

C:\Program Files\MongoDB\Server\3.2\bin\

Then try below code in command prompt to run mongo server from parent folder of data folder.

mongod -dbpath ./data

For my case I am unable to run mongo from command prompt(normal mode). You should run as administrator. It also works on git bash.

You can do this too

Before you use this you must declare the DB facade in the controller Simply put this line for that

use Illuminate\Support\Facades\DB;

Now you can get a row using this

$getUserByEmail = DB::table('users')->where('email', $email)->first();

or by this too

$getUserByEmail = DB::select('SELECT * FROM users WHERE email = ?' , ['[email protected]']);

This one returns an array with only one item in it and while the first one returns an object. Keep that in mind.

Hope this helps.

Try this:

I had this issue after installing dotnetframework4.5.
Open path below:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" ( in 64 bits machine)
or
"C:\Program Files\Microsoft Visual Studio 10.0\VC\bin" (in 32 bits machine)
In this path find file cvtres.exe and rename it to cvtres1.exe then compile your project again.

Since you already have sent some data,

System.out.println("going to demo.jsp");

you won't be able to send a redirect.

To people that can't get above fixes working.

Had to change file ssl.py to fix it. Look for function create_default_context and change line:

context = SSLContext(PROTOCOL_SSLv23)

to

context = SSLContext(PROTOCOL_TLSv1)

Maybe someone can create easier solution without editing ssl.py?

When trying to calculate the total of a particular group of files within a directory the -s option does not work (in Hadoop 2.7.1). For example:

Directory structure:

some_dir
+abc.txt    
+count1.txt 
+count2.txt 
+def.txt    

Assume each file is 1 KB in size. You can summarize the entire directory with:

hdfs dfs -du -s some_dir
4096 some_dir

However, if I want the sum of all files containing "count" the command falls short.

hdfs dfs -du -s some_dir/count*
1024 some_dir/count1.txt
1024 some_dir/count2.txt

To get around this I usually pass the output through awk.

hdfs dfs -du some_dir/count* | awk '{ total+=$1 } END { print total }'
2048 

I think you are looking for inputstream.available(). It does not tell you whether its empty but it can give you an indication as to whether data is there to be read or not.

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

git config --global core.askpass "git-gui--askpass"

This worked for me. It may take 3-5 secs for the prompt to appear just enter your login credentials and you are good to go.

Use this syntax:

CREATE TEMPORARY TABLE t1 (select * from t2);

If you are unsure of the size of the array or if it can change you can do this to have a static array.

ArrayList<Player> thePlayersList = new ArrayList<Player>(); 

thePlayersList.add(new Player(1));
thePlayersList.add(new Player(2));
.
.
//Some code here that changes the number of players e.g

Players[] thePlayers = thePlayersList.toArray();

You cannot select on specific values (or types of values). You'd either make a reverse index (map numbers back to (lists of) keys) or you have to loop through all values every time.

If you are processing numbers in arbitrary order anyway, you may as well loop through all items:

for key, value in inputdict.items():
    # do something with value
    inputdict[key] = newvalue

otherwise I'd go with the reverse index:

from collections import defaultdict

reverse = defaultdict(list)
for key, value in inputdict.items():
    reverse[value].append(key)

Now you can look up keys by value:

for key in reverse[value]:
    inputdict[key] = newvalue

Using Oracle's sub query factory clause: "WITH", you can select numbers from 1 to 100:

WITH t(n) AS (
  SELECT 1 from dual
  UNION ALL
    SELECT n+1 FROM t WHERE n < 100
)
SELECT * FROM t;

Give the parent a style of overflow: hidden. If it is overlapping sibling elements, you will have to put it inside of a container with a fixed height/width and give that a style of overflow: hidden.

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.

You should first consider making GetStringData an async method and have it await the task returned from MyAsyncMethod.

If you're absolutely sure that you don't need to handle exceptions from MyAsyncMethod or know when it completes, then you can do this:

public string GetStringData()
{
  var _ = MyAsyncMethod();
  return "hello world";
}

BTW, this is not a "common problem". It's very rare to want to execute some code and not care whether it completes and not care whether it completes successfully.

Update:

Since you're on ASP.NET and wanting to return early, you may find my blog post on the subject useful. However, ASP.NET was not designed for this, and there's no guarantee that your code will run after the response is returned. ASP.NET will do its best to let it run, but it can't guarantee it.

So, this is a fine solution for something simple like tossing an event into a log where it doesn't really matter if you lose a few here and there. It's not a good solution for any kind of business-critical operations. In those situations, you must adopt a more complex architecture, with a persistent way to save the operations (e.g., Azure Queues, MSMQ) and a separate background process (e.g., Azure Worker Role, Win32 Service) to process them.

# yum install -y https://centos7.iuscommunity.org/ius-release.rpm

I hope it will help Someone to resolve "gcc" issue.

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

See themes on android: http://developer.android.com/guide/topics/ui/themes.html.

Under themes.xml there should be android:windowAnimationStyle where you can see the declaration of the style in styles.xml.

Example implementation:

<style name="AppTheme" parent="...">

    ...

    <item name="android:windowAnimationStyle">@style/WindowAnimationStyle</item>

</style>

<style name="WindowAnimationStyle">
    <item name="android:windowEnterAnimation">@android:anim/fade_in</item>
    <item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>

2014 and above at least you can set a default and it will take that and NOT error when you do not pass that parameter. Partial Example: the 3rd parameter is added as optional. exec of the actual procedure with only the first two parameters worked fine

create procedure getlist

   @SortOrder int,
   @contestantsOnly bit = 0

Stop abusing private fields!!!

The comments here seem to be overwhelmingly supportive towards using private fields. Well, then I have something different to say.

Are private fields good in principle? Yes. But saying that a golden rule is make everything private when you're not sure is definitely wrong! You won't see the problem until you run into one. In my opinion, you should mark fields as protected if you're not sure.

There are two cases you want to extend a class:

• You want to add extra functionality to a base class
• You want to modify existing class that's outside the current package (in some libraries perhaps)

There's nothing wrong with private fields in the first case. The fact that people are abusing private fields makes it so frustrating when you find out you can't modify shit.

Consider a simple library that models cars:

class Car {
    private screw;
    public assembleCar() {
       screw.install();
    };
    private putScrewsTogether() {
       ...
    };
}

The library author thought: there's no reason the users of my library need to access the implementation detail of assembleCar() right? Let's mark screw as private.

Well, the author is wrong. If you want to modify only the assembleCar() method without copying the whole class into your package, you're out of luck. You have to rewrite your own screw field. Let's say this car uses a dozen of screws, and each of them involves some untrivial initialization code in different private methods, and these screws are all marked private. At this point, it starts to suck.

Yes, you can argue with me that well the library author could have written better code so there's nothing wrong with private fields. I'm not arguing that private field is a problem with OOP. It is a problem when people are using them.

The moral of the story is, if you're writing a library, you never know if your users want to access a particular field. If you're unsure, mark it protected so everyone would be happier later. At least don't abuse private field.

I very much support Nick's answer.

tl;dr

LocalDateTime.parse( 
    "2012-07-10 14:58:00.000000".replace( " " , "T" )  
)

Microseconds do not fit

You are attempting to squeeze a value with microseconds (six decimal digits) into a data type capable only of milliseconds resolution (three decimal digits). That is impossible.

Instead, use a data type with fine enough resolution. The java.time classes use nanosecond resolution (nine decimal digits).

Unzoned input does not fit a zoned type

You are attempting to put a value lacking any offset-from-UTC or time zone into a data type (Date) that only represents values in UTC. So you are adding information (UTC offset) not intended by the input.

Use an appropriate data type instead. Specifically, java.time.LocalDateTime.

Case-sensitive

Other Answers and Comments correctly explain that the formatting pattern codes are case-sensitive. So MM and mm have different effects.

Avoid legacy classes

The troublesome old date-time classes bundled with the earliest versions of Java are now legacy, supplanted by the java.time classes built into Java 8 and later.

ISO 8601

Your input strings nearly comply with the ISO 8601 standard formats. Replace the SPACE in the middle with a T to comply fully.

The java.time classes use the standard formats by default when parsing/generating strings. So no need to specify a formatting pattern.

Date-time objects have no "format"

and I need the resultant date object to be of the same format.

No, date-time objects do not have a "format". Do not conflate date-time objects with mere strings. Strings are inputs and outputs of the objects. The objects maintain their own internal representions of the date-time info, the details of which are irrelevant to us as calling programmers.

java.time

Your input lacks any indicator of offset-from-UTC or troublesome me zone. So we parse as a LocalDateTime objects which lacks those concepts.

String input = "2012-07-10 14:58:00.000000".replace( " " , "T" ) ;
LocalDateTime ldt = LocalDateTime.parse( input ) ;

Generating strings

To generate a String representing the value of your LocalDateTime:

• Call toString to get a String in standard ISO 8601 format.
• Use DateTimeFormatter for producing strings in either custom formats or automatically-localized formats.

Search Stack Overflow for more info as these topics have been covered many many times already.

ZonedDateTime

A LocalDateTime does not represent an exact point on the timeline.

To determine an actual moment, assign a time zone. For example noon in Kolkata India comes much earlier than noon in Paris France. Noon without a time zone could be happening at any point over a range of about 26-27 hours.

ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = ldt.atZone( z ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

According to Java Persistence with Hibernate

mapping collections of value types with annotations [...]. At the time of writing it isn't part of the Java Persistence standard

If you were using Hibernate, you could do something like:

@org.hibernate.annotations.CollectionOfElements(
    targetElement = java.lang.String.class
)
@JoinTable(
    name = "foo",
    joinColumns = @JoinColumn(name = "foo_id")
)
@org.hibernate.annotations.IndexColumn(
    name = "POSITION", base = 1
)
@Column(name = "baz", nullable = false)
private List<String> arguments = new ArrayList<String>();

Update: Note, this is now available in JPA2.

git reset HEAD~1 if you don't want your changes to be gone(unstaged changes). Change, commit and push again git push -f [origin] [branch]

Try this C# Reflection link.

Note I think that BindingFlags.Instance and BindingFlags.Static are exclusive.

For normal users. Open the inspect window of current page. And type in:

l = document.getElementsByTagName("a");
for (var i =0; i<l.length; i++) {
    l[i].href = "";
}

Then you shall not see the url links in print preview.

You can get a client with new session directly like below.

 s3_client = boto3.client('s3', 
                      aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, 
                      aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY, 
                      region_name=REGION_NAME
                      )

The User Scripts menu has a lot of goodies in it, and it's relatively easy to add your own. For example, I added a shortcut and bound it to cmd-opt-- to insert a comment divider and a #pragma mark in my code to quickly break up a file.

  #!/bin/sh
  echo -n "//================....================
  #pragma mark "

When I hit cmd-opt--, these lines are inserted into my code and the cursor is pre-positioned to edit the pragma mark component, which shows up in the symbol popup.

Most times, it's not a login issue, but an issue with creating the database itself. So if there is an error creating your database, it would not be created in the first place. In which case if you tried to log in, regardless of the user, login would fail. This usually happens due to logical misinterpretation of the db context.

Visit the site in a browser and REALLY read those error logs, this can help you spot the problem with you code (usually conflicting logic problems with the model).

In my case, the code compiled fine, same login problem, while I was still downloading management studio, I went through the error log, fixed my db context constraints and site started running fine....meanwhile management studio is still downloading

You can get all the IP addresses with GetHostAddresses like this:

$ips = [System.Net.Dns]::GetHostAddresses("yourhosthere")

You can iterate over them like so:

[System.Net.Dns]::GetHostAddresses("yourhosthere") | foreach {echo $_.IPAddressToString }

A server may have more than one IP, so this will return an array of IPs.

ReSharper offers property generation in its extensive feature set. (It's not cheap though, unless you're working on an open-source project.)

Output Caching in MVC

[OutputCache(NoStore = true, Duration = 0, Location="None", VaryByParam = "*")]

OR
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "None")]

if you want to bookkeep some variable before page refresh

$(window).on('beforeunload', function(){
    // your logic here
});

if you want o load some content base on some condition

$(window).on('load', function(){
    // your logic here`enter code here`
});

use this on:

$('body').on('focus',".datumwaehlen", function(){
    $(this).datepicker({
        minDate: -20
    });
});

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.

Server side Comments:

Razor .cshtml

Like so:

@* Comment goes here *@

.aspx
For those looking for the older .aspx view (and Asp.Net WebForms) server side comment syntax:

<%-- Comment goes here --%>

Client Side Comments

HTML Comment

<!-- Comment goes here -->

Javascript Comment

// One line Comment goes Here
/* Multiline comment
   goes here */

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).

My solution to this was to write the script block dynamically with [scriptblock]:Create:

# Or build a complex local script with MARKERS here, and do substitutions
# I was sending install scripts to the remote along with MSI packages
# ...for things like Backup and AV protection etc.

$p1 = "good stuff"; $p2 = "better stuff"; $p3 = "best stuff"; $etc = "!"
$script = [scriptblock]::Create("MyScriptOnRemoteServer.ps1 $p1 $p2 $etc")
#strings get interpolated/expanded while a direct scriptblock does not

# the $parms are now expanded in the script block itself
# ...so just call it:
$result = invoke-command $computer -script $script

Passing arguments was very frustrating, trying various methods, e.g.,
-arguments, $using:p1, etc. and this just worked as desired with no problems.

Since I control the contents and variable expansion of the string which creates the [scriptblock] (or script file) this way, there is no real issue with the "invoke-command" incantation.

(It shouldn't be that hard. :) )

You can not add links from CSS, you will have to do so from the HTML code explicitly. For example, something like this:

<a href="whatever.html"><li id="header"></li></a>

Change var data = 'id='+ id & 'name='+ name; as below,

use this instead.....

var data = "id="+ id + "&name=" + name;

this will going to work fine:)

You can use String.Remove to delete from a specified position to the end of the string.

myString = myString.Remove(myString.Length - 3);

This might be handy for those who want to use the current date in more than one class.

extension String {


func  getCurrentTime() -> String {

    let date = Date()
    let calendar = Calendar.current


    let year = calendar.component(.year, from: date)
    let month = calendar.component(.month, from: date)
    let day = calendar.component(.day, from: date)
    let hour = calendar.component(.hour, from: date)
    let minutes = calendar.component(.minute, from: date)
    let seconds = calendar.component(.second, from: date)

    let realTime = "\(year)-\(month)-\(day)-\(hour)-\(minutes)-\(seconds)"

    return realTime
}

}

Usage

        var time = ""
        time = time.getCurrentTime()
        print(time)   // 1900-12-09-12-59

sudo -sH
java -jar filename.jar

Keep in mind to never run executable file in as root.

This solutions works fine for me.

utils/newid.js:

let lastId = 0;

export default function(prefix='id') {
    lastId++;
    return `${prefix}${lastId}`;
}

And I can use it like this:

import newId from '../utils/newid';

React.createClass({
    componentWillMount() {
        this.id = newId();
    },
    render() {
        return (
            <label htmlFor={this.id}>My label</label>
            <input id={this.id} type="text"/>
        );
    }
});

But it won’t work in isomorphic apps.

Added 17.08.2015. Instead of custom newId function you can use uniqueId from lodash.

Updated 28.01.2016. It’s better to generate ID in componentWillMount.

I've written this little plugin for jQuery which will make all calls to .val(value) update the angular element if present:

(function($, ng) {
  'use strict';

  var $val = $.fn.val; // save original jQuery function

  // override jQuery function
  $.fn.val = function (value) {
    // if getter, just return original
    if (!arguments.length) {
      return $val.call(this);
    }

    // get result of original function
    var result = $val.call(this, value);

    // trigger angular input (this[0] is the DOM object)
    ng.element(this[0]).triggerHandler('input');

    // return the original result
    return result; 
  }
})(window.jQuery, window.angular);

Just pop this script in after jQuery and angular.js and val(value) updates should now play nice.

Minified version:

!function(n,t){"use strict";var r=n.fn.val;n.fn.val=function(n){if(!arguments.length)return r.call(this);var e=r.call(this,n);return t.element(this[0]).triggerHandler("input"),e}}(window.jQuery,window.angular);

Since 0.14.1, you can now do nlargest and nsmallest on a groupby object:

In [23]: df.groupby('id')['value'].nlargest(2)
Out[23]: 
id   
1   2    3
    1    2
2   6    4
    5    3
3   7    1
4   8    1
dtype: int64

There's a slight weirdness that you get the original index in there as well, but this might be really useful depending on what your original index was.

If you're not interested in it, you can do .reset_index(level=1, drop=True) to get rid of it altogether.

(Note: From 0.17.1 you'll be able to do this on a DataFrameGroupBy too but for now it only works with Series and SeriesGroupBy.)

The interpretation of the backspace and carriage return characters is left to the software you use for display. A terminal emulator, when displaying \b would move the cursor one step back, and when displaying \r to the beginning of the line. If you print these characters somewhere else, like a text file, the software may choose. to do something else.

ImageIO.write() will compress the image by default - the compressed image has a smaller size but looks strange sometimes. I use BufferedOutputStream to save the byte array data - this will keep the original image size.

Here is the code:

import javax.xml.bind.DatatypeConverter;
import java.io.*;

public class ImageTest {
    public static void main(String[] args) {
        String base64String = "data:image/jpeg;base64,iVBORw0KGgoAAAANSUhEUgAAAHkAAAB5C...";
        String[] strings = base64String.split(",");
        String extension;
        switch (strings[0]) {//check image's extension
            case "data:image/jpeg;base64":
                extension = "jpeg";
                break;
            case "data:image/png;base64":
                extension = "png";
                break;
            default://should write cases for more images types
                extension = "jpg";
                break;
        }
        //convert base64 string to binary data
        byte[] data = DatatypeConverter.parseBase64Binary(strings[1]);
        String path = "C:\\Users\\Ene\\Desktop\\test_image." + extension;
        File file = new File(path);
        try (OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(file))) {
            outputStream.write(data);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

I use the Description attribute from the System.ComponentModel namespace. Simply decorate the enum:

private enum PublishStatusValue
{
    [Description("Not Completed")]
    NotCompleted,
    Completed,
    Error
};

Then use this code to retrieve it:

public static string GetDescription<T>(this T enumerationValue)
    where T : struct
{
    Type type = enumerationValue.GetType();
    if (!type.IsEnum)
    {
        throw new ArgumentException("EnumerationValue must be of Enum type", "enumerationValue");
    }

    //Tries to find a DescriptionAttribute for a potential friendly name
    //for the enum
    MemberInfo[] memberInfo = type.GetMember(enumerationValue.ToString());
    if (memberInfo != null && memberInfo.Length > 0)
    {
        object[] attrs = memberInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);

        if (attrs != null && attrs.Length > 0)
        {
            //Pull out the description value
            return ((DescriptionAttribute)attrs[0]).Description;
        }
    }
    //If we have no description attribute, just return the ToString of the enum
    return enumerationValue.ToString();
}

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

ES6:

function params(data) {_x000D_
  return Object.keys(data).map(key => `${key}=${encodeURIComponent(data[key])}`).join('&');_x000D_
}_x000D_
_x000D_
console.log(params({foo: 'bar'}));_x000D_
console.log(params({foo: 'bar', baz: 'qux$'}));

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.

If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.

Yep, Oracle has temporary tables. Here is a link to an AskTom article describing them and here is the official oracle CREATE TABLE documentation.

However, in Oracle, only the data in a temporary table is temporary. The table is a regular object visible to other sessions. It is a bad practice to frequently create and drop temporary tables in Oracle.

CREATE GLOBAL TEMPORARY TABLE today_sales(order_id NUMBER)
ON COMMIT PRESERVE ROWS;

Oracle 18c added private temporary tables, which are single-session in-memory objects. See the documentation for more details. Private temporary tables can be dynamically created and dropped.

CREATE PRIVATE TEMPORARY TABLE ora$ptt_today_sales AS
SELECT * FROM orders WHERE order_date = SYSDATE;

Temporary tables can be useful but they are commonly abused in Oracle. They can often be avoided by combining multiple steps into a single SQL statement using inline views.

I had this problem with only with redirectMode="ResponseRewrite" (redirectMode="ResponseRedirect" worked fine) and none of the above solutions helped my resolve the issue. However, once I changed the server's application pool's "Managed Pipeline Mode" from "Classic" to "Integrated" the custom error page appeared as expected.

With Python 3.8 this workes for me. For instance to execute a python script within the venv:

    import subprocess
    import sys
    res = subprocess.run([
              sys.executable,            # venv3.8/bin/python
              'main.py', '--help',], 
            stdout=PIPE, 
            text=True)
    print(res.stdout)

var dictionary = {
        "data":[{"id":"0","name":"ABC"}, {"id":"1","name":"DEF"}],
        "images": [ {"id":"0","name":"PQR"},"id":"1","name":"xyz"}]
};


for (var key in dictionary) {
    var getKey = dictionary[key];
    getKey.forEach(function(item) {
        console.log(item.name + ' ' + item.id);
    });
}

An alternative that also has the added benefit of easily logging its output:

hexs = "13 00 00 00 08 00"
logging.debug(hexs)
key = bytearray.fromhex(hexs)

allows you to do easy substitutions like so:

hexs = "13 00 00 00 08 {:02X}".format(someByte)
logging.debug(hexs)
key = bytearray.fromhex(hexs)

This is not perfect, but it works.

<asp:LinkButton id="lbnkVidTtile1" runat="Server" 
    CssClass="bodytext" Text='<%# Eval("newvideotitle") %>'
    OnClientClick="return PostToNewWindow();"  />

<script type="text/javascript">
function PostToNewWindow()
{
    originalTarget = document.forms[0].target;
    document.forms[0].target='_blank';
    window.setTimeout("document.forms[0].target=originalTarget;",300);
    return true;
}
</script>

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

Some of you may be getting this error because Git doesn't know which branch you're trying to push.

If your error message also includes

error: failed to push some refs to '[email protected]:jkubicek/my_proj.git'
hint: Updates were rejected because a pushed branch tip is behind its remote
hint: counterpart. If you did not intend to push that branch, you may want to
hint: specify branches to push or set the 'push.default' configuration
hint: variable to 'current' or 'upstream' to push only the current branch.

then you may want to follow the handy tips from Jim Kubicek, Configure Git to Only Push Current Branch, to set the default branch to current.

git config --global push.default current

Hope this helps, with Serverless framework you can do something like this:

1. Add these things in your serverless.yml file:

plugins: - serverless-webpack custom: webpackIncludeModules: forceInclude: - <your package name> (for example: node-fetch) 2. Then create your Lambda function, deploy it by serverless deploy, the package that included in serverless.yml will be there for you.

For more information about serverless: https://serverless.com/framework/docs/providers/aws/guide/quick-start/

I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:

<form action="some.jsp">
  <select name="item">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
  </select>
  <input type="submit" value="Submit">
</form>

in some.jsp

request.getParameter("item");

this line will return the selected option (from the example it is: 1, 2 or 3)

var x = $($('div').html($('#container').clone())).html();

I am just providing another case where you can get this error message. The solution will be the same as Adam has mentioned above. This is from a real code and I renamed the class name.

class FooReader {
  public:
     /** Constructor */
     FooReader() : d(new FooReaderPrivate(this)) { }  // will not compile here
     .......
  private:
     FooReaderPrivate* d;
};

====== In a separate file =====
class FooReaderPrivate {
  public:
     FooReaderPrivate(FooReader*) : parent(p) { }
  private:
     FooReader* parent;
};

The above will no pass the compiler and get error: invalid use of incomplete type FooReaderPrivate. You basically have to put the inline portion into the *.cpp implementation file. This is OK. What I am trying to say here is that you may have a design issue. Cross reference of two classes may be necessary some cases, but I would say it is better to avoid them at the start of the design. I would be wrong, but please comment then I will update my posting.

I think you can't increase the time for query execution, but you need to increase the timeout for the request.

Execution Timeout Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET. (Default time is 110 seconds.)

For Details, please have a look at https://msdn.microsoft.com/en-us/library/e1f13641%28v=vs.100%29.aspx

You can do in the web.config. e.g

<httpRuntime maxRequestLength="2097152" executionTimeout="600" />

You will need to clone the ArrayList by hand (by iterating over it and copying each element to a new ArrayList), because clone() will not do it for you. Reason for this is that the objects contained in the ArrayList may not implement Clonable themselves.

Edit: ... and that is exactly what Varkhan's code does.

If it were an "ordered factor" things would be different. Which is not to say I like "ordered factors", I don't, only to say that some relationships are defined for 'ordered factors' that are not defined for "factors". Factors are thought of as ordinary categorical variables. You are seeing the natural sort order of factors which is alphabetical lexical order for your locale. If you want to get an automatic coercion to "numeric" for every column, ... dates and factors and all, then try:

sapply(df, function(x) max(as.numeric(x)) )   # not generally a useful result

Or if you want to test for factors first and return as you expect then:

sapply( df, function(x) if("factor" %in% class(x) ) { 
            max(as.numeric(as.character(x)))
            } else { max(x) } )

@Darrens comment does work better:

 sapply(df, function(x) max(as.character(x)) )  

max does succeed with character vectors.

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

public boolean isElementFound( String text) {
        try{
            WebElement webElement = appiumDriver.findElement(By.xpath(text));
            System.out.println("isElementFound : true :"+text + "true");
        }catch(NoSuchElementException e){
            System.out.println("isElementFound : false :"+text);
            return false;
        }
        return true;
    }

    text is the xpath which you would be passing when calling the function.
the return value will be true if the element is present else false if element is not pressent

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

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

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

Refer to this documentation.

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

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

You do not need to call toString explicitly.

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

I was using ubuntu 18 and simply installed MySQL (password:root) with the following commands.

sudo apt install mysql-server
sudo mysql_secure_installation

When I tried to log in with the normal ubuntu user it was throwing me this issue.

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

But I was able to login to MySQL via the super user. Using the following commands I was able to log in via a normal user.

sudo mysql    
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
exit;

Then you should be able to login to Mysql with the normal account.

That answer really helped me, in my case i had to filter some elements out and have special aligment on their error div,

errorPlacement:function(error,element) {
    if (element.attr("id") == "special_element") {
        // special align
    } else { // default error scheme
        error.insertAfter(element);
    }
}

You can remove the UI to control this with:

frmYour.MinimizeBox = False
frmYour.MaximizeBox = False

Perl might be overkill, but it works just as well.

Removes all lines which are completely blank:

perl -ne 'print if /./' file

Removes all lines which are completely blank, or only contain whitespace:

perl -ne 'print if ! /^\s*$/' file

Variation which edits the original and makes a .bak file:

perl -i.bak -ne 'print if ! /^\s*$/' file

You can use this code. This works very fast!

public String[] loadFileToArray(String fileName) throws IOException {
    String s = new String(Files.readAllBytes(Paths.get(fileName)));
    return Arrays.stream(s.split("\n")).toArray(String[]::new);
}

A direct process to install / configure Plugin Manager :

1. Download the latest version of NotepadPlus Plugin Manager from the official Github handle.
2. Extract the zip file.
3. Copy the pluginmanager.dll file and paste in C:\Program Files\Notepad++\Plugins\PluginManager directory.
4. Restart the Notepad++

Note: Create the PluginManager directory if it is not present.

ALTER TABLE TableName ADD NewColumnName INTEGER, FOREIGN KEY(NewColumnName) REFERENCES [ForeignKey_TableName](Foreign_Key_Column)

Using you current code, make this tweak:

public void listf(String directoryName, List<File> files) {
    File directory = new File(directoryName);

    // Get all files from a directory.
    File[] fList = directory.listFiles();
    if(fList != null)
        for (File file : fList) {      
            if (file.isFile()) {
                files.add(file);
            } else if (file.isDirectory()) {
                listf(file.getAbsolutePath(), files);
            }
        }
    }
}

You can also run conda init as below,

C:\ProgramData\Anaconda3\Scripts\conda init cmd.exe

or

C:\ProgramData\Anaconda3\Scripts\conda init powershell

Note that the execution policy of powershell must be set, e.g. using Set-ExecutionPolicy Unrestricted.

Use df.schema.names:

spark.version
# u'2.2.0'

df = spark.createDataFrame([("foo", 1), ("bar", 2)])
df.show()
# +---+---+ 
# | _1| _2|
# +---+---+
# |foo|  1| 
# |bar|  2|
# +---+---+

df.schema.names
# ['_1', '_2']

for i in df.schema.names:
  # df_new = df.withColumn(i, [do-something])
  print i
# _1
# _2

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

Coffee Cup Just released one. July 6, 2010 http://www.coffeecup.com/html-editor/

I confronted similar issue when I wanted to post image file to a rest API from Python (Not wechat API though). The solution for me was to use 'data' parameter to post the file in binary data instead of 'files'. Requests API reference

data = open('your_image.png','rb').read()
r = requests.post(your_url,data=data)

Hope this works for your case.

There is no equivalent to LINQ for Java. But there is some of the external API which is looks like LINQ such as https://github.com/nicholas22/jpropel-light, https://code.google.com/p/jaque/

If you want to use steffens21's approach with unittest.TestLoader, you can modify the original test loader (see unittest.py):

        if not testCaseNames and hasattr(testCaseClass, 'runTest'):
            testCaseNames = ['runTest']

I am using laravel5.2 and we can add joins with different options, you can modify as per your requirement.

Option 1:    
    DB::table('users')
            ->join('contacts', function ($join) {
                $join->on('users.id', '=', 'contacts.user_id')->orOn(...);//you add more joins here
            })// and you add more joins here
        ->get();

Option 2:
    $users = DB::table('users')
        ->join('contacts', 'users.id', '=', 'contacts.user_id')
        ->join('orders', 'users.id', '=', 'orders.user_id')// you may add more joins
        ->select('users.*', 'contacts.phone', 'orders.price')
        ->get();

option 3:
    $users = DB::table('users')
        ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
        ->leftJoin('...', '...', '...', '...')// you may add more joins
        ->get();

use dirname(__FILE__) in a global configuration file.

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

you should check if it is less than 10... not looking for the length of it , because this is a number and not a string

cleaned solution :

$.fn.donetyping = function(callback, delay){
  delay || (delay = 1000);
  var timeoutReference;
  var doneTyping = function(elt){
    if (!timeoutReference) return;
    timeoutReference = null;
    callback(elt);
  };

  this.each(function(){
    var self = $(this);
    self.on('keyup',function(){
      if(timeoutReference) clearTimeout(timeoutReference);
      timeoutReference = setTimeout(function(){
        doneTyping(self);
      }, delay);
    }).on('blur',function(){
      doneTyping(self);
    });
  });

  return this;
};

Warning: Both solutions given ( astype() and apply() ) do not preserve NULL values in either the nan or the None form.

import pandas as pd
import numpy as np

df = pd.DataFrame([None,'string',np.nan,42], index=[0,1,2,3], columns=['A'])

df1 = df['A'].astype(str)
df2 =  df['A'].apply(str)

print df.isnull()
print df1.isnull()
print df2.isnull()

I believe this is fixed by the implementation of to_string()

In intellij8 I was using a specific plugin "Jar Tool" that is configurable and allows to pack a JAR archive.

Creating and destroying the connections in each query maybe complicated, i had some headaches with a server migration when i decided to install MariaDB instead MySQL. For some reason in the file etc/my.cnf the parameter wait_timeout had a default value of 10 sec (it causes that the persistence can't be implemented). Then, the solution was set it in 28800, that's 8 hours. Well, i hope help somebody with this "güevonada"... excuse me for my bad english.

NSString * str = [componentsJoinedByString:@""];

and you have dic or multiple array then used bellow

NSString * result = [[array valueForKey:@"description"] componentsJoinedByString:@""];   

If you want your application on same port i.e port=5000 then just in your terminal run this command:

fuser -k 5000/tcp

and then run:

python app.py

If you want to run on a specified port, e.g. if you want to run on port=80, in your main file just mention this:

if __name__ == '__main__':  
    app.run(host='0.0.0.0', port=80)

It's simple. Just do this:

#include <iostream>
#include <vector>
#include <string.h>

int main(int argc, char *argv[])
{
    std::vector<std::string> argList;
    for(int i=0;i<argc;i++)
        argList.push_back(argv[i]);
    //now you can access argList[n]
}

@Benjamin Lindley You are right. This is not a good solution. Please read the one answered by juanchopanza.

In my experience it may be the result of auto-generation by a string-based tools, where the author did not understand the rules of HTML.

When some developers generate HTML without the use of special XML-oriented tools, they may try to be sure the resulting HTML is valid by taking the approach that everything must be escaped.

Referring to your example, the reason why every occurrence of " is represented by " could be because using that approach, you can safely use such "special" characters in both attributes and values.

Another motivation I've seen is where people believe, "We must explicitly show that our symbols are not part of the syntax." Whereas, valid HTML can be created by using the proper string-manipulation tools, see the previous paragraph again.

Here is some pseudo-code loosely based on C#, although it is preferred to use valid methods and tools:

public class HtmlAndXmlWriter
{
    private string Escape(string badString)
    {
        return badString.Replace("&", "&amp;").Replace("\"", "&quot;").Replace("'", "&apos;").Replace(">", "&gt;").Replace("<", "&lt;");

    }

    public string GetHtmlFromOutObject(Object obj)
    {
        return "<div class='type_" + Escape(obj.Type) + "'>" + Escape(obj.Value) + "</div>";    

    }

}

It's really very common to see such approaches taken to generate HTML.

Your array is of byte primitives, but you're trying to call a method on them.

You don't need to do anything explicit to convert a byte to an int, just:

int i=rno[0];

...since it's not a downcast.

Note that the default behavior of byte-to-int conversion is to preserve the sign of the value (remember byte is a signed type in Java). So for instance:

byte b1 = -100;
int i1 = b1;
System.out.println(i1); // -100

If you were thinking of the byte as unsigned (156) rather than signed (-100), as of Java 8 there's Byte.toUnsignedInt:

byte b2 = -100; // Or `= (byte)156;`
int = Byte.toUnsignedInt(b2);
System.out.println(i2); // 156

Prior to Java 8, to get the equivalent value in the int you'd need to mask off the sign bits:

byte b2 = -100; // Or `= (byte)156;`
int i2 = (b2 & 0xFF);
System.out.println(i2); // 156

Just for completeness #1: If you did want to use the various methods of Byte for some reason (you don't need to here), you could use a boxing conversion:

Byte b = rno[0]; // Boxing conversion converts `byte` to `Byte`
int i = b.intValue();

Or the Byte constructor:

Byte b = new Byte(rno[0]);
int i = b.intValue();

But again, you don't need that here.

Just for completeness #2: If it were a downcast (e.g., if you were trying to convert an int to a byte), all you need is a cast:

int i;
byte b;

i = 5;
b = (byte)i;

This assures the compiler that you know it's a downcast, so you don't get the "Possible loss of precision" error.

import re

htmlString = '</dd><dt> Fine, thank you.&#160;</dt><dd> Molt bé, gràcies. (<i>mohl behh, GRAH-syuhs</i>)'

SearchStr = '(\<\/dd\>\<dt\>)+ ([\w+\,\.\s]+)([\&\#\d\;]+)(\<\/dt\>\<dd\>)+ ([\w\,\s\w\s\w\?\!\.]+) (\(\<i\>)([\w\s\,\-]+)(\<\/i\>\))'

Result = re.search(SearchStr.decode('utf-8'), htmlString.decode('utf-8'), re.I | re.U)

print Result.groups()

Works that way. The expression contains non-latin characters, so it usually fails. You've got to decode into Unicode and use re.U (Unicode) flag.

I'm a beginner too and I faced that issue a couple of times myself.

Adding an answer because none of the existing answers specifically address the confusion in the official literature.

Generator functions are ordinary functions defined using yield instead of return. When called, a generator function returns a generator object, which is a kind of iterator - it has a next() method. When you call next(), the next value yielded by the generator function is returned.

Either the function or the object may be called the "generator" depending on which Python source document you read. The Python glossary says generator functions, while the Python wiki implies generator objects. The Python tutorial remarkably manages to imply both usages in the space of three sentences:

Generators are a simple and powerful tool for creating iterators. They are written like regular functions but use the yield statement whenever they want to return data. Each time next() is called on it, the generator resumes where it left off (it remembers all the data values and which statement was last executed).

The first two sentences identify generators with generator functions, while the third sentence identifies them with generator objects.

Despite all this confusion, one can seek out the Python language reference for the clear and final word:

The yield expression is only used when defining a generator function, and can only be used in the body of a function definition. Using a yield expression in a function definition is sufficient to cause that definition to create a generator function instead of a normal function.

When a generator function is called, it returns an iterator known as a generator. That generator then controls the execution of a generator function.

So, in formal and precise usage, "generator" unqualified means generator object, not generator function.

The above references are for Python 2 but Python 3 language reference says the same thing. However, the Python 3 glossary states that

generator ... Usually refers to a generator function, but may refer to a generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity.

You can have a table variable as a return type and then update or insert on a table based on that output. In other words, you can set the variable output as the original table, make the modifications and then do an insert to the original table from function output. It is a little hack but if you insert the @output_table from the original table and then say for example: Insert into my_table select * from my_function

then you can achieve the result.

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

@Component({

You will have to modify the below line:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

modalRegister is the ID and hence requires a preceding # for ID reference in html.

So, the modified html code snippet would be as follows:

<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>

async is used for binding to Observables and Promises, but it seems like you're binding to a regular object. You can just remove both async keywords and it should probably work.

In C# These ways you can Solve the problem, In UIkit these methods are available.

Label.Font = Label.Font.WithSize(5.0f);
       Or
Label.Font = UIFont.FromName("Copperplate", 10.0f);  
       Or
Label.Font = UIFont.WithSize(5.0f);

You don't need to use linq since List<T> provides the methods to do this:

int index = lst.FindLastIndex(c => c.Number == textBox6.Text);
if(index != -1)
{
    lst[index] = new Class1() { ... };
}

Where Xcode stores simulators in 2019+ Catalina, Xcode 11.0

Runtimes

$ open ~/Library/Developer/CoreSimulator/Profiles/Runtimes

For example: iOS 13.0, watchOS 6.0 These take the most space, by far. Each one can be up to ~5GB

Devices

$ open ~/Library/Developer/CoreSimulator/Devices

For example: iPhone Xr, iPhone 11 Pro Max. These are typically <15 mb each.

Explanation

Simulators are split between runtimes and devices. If you run $ xcrun simctl list you can see an overview, but if you want to find the physical location of these simulators, look in these directories I've shown.

It's totally safe to delete runtimes you don't support. You can reinstall these later if you want.

and the initial question was... how to convert scatter values to grid values, right? histogram2d does count the frequency per cell, however, if you have other data per cell than just the frequency, you'd need some additional work to do.

x = data_x # between -10 and 4, log-gamma of an svc
y = data_y # between -4 and 11, log-C of an svc
z = data_z #between 0 and 0.78, f1-values from a difficult dataset

So, I have a dataset with Z-results for X and Y coordinates. However, I was calculating few points outside the area of interest (large gaps), and heaps of points in a small area of interest.

Yes here it becomes more difficult but also more fun. Some libraries (sorry):

from matplotlib import pyplot as plt
from matplotlib import cm
import numpy as np
from scipy.interpolate import griddata

pyplot is my graphic engine today, cm is a range of color maps with some initeresting choice. numpy for the calculations, and griddata for attaching values to a fixed grid.

The last one is important especially because the frequency of xy points is not equally distributed in my data. First, let's start with some boundaries fitting to my data and an arbitrary grid size. The original data has datapoints also outside those x and y boundaries.

#determine grid boundaries
gridsize = 500
x_min = -8
x_max = 2.5
y_min = -2
y_max = 7

So we have defined a grid with 500 pixels between the min and max values of x and y.

In my data, there are lots more than the 500 values available in the area of high interest; whereas in the low-interest-area, there are not even 200 values in the total grid; between the graphic boundaries of x_min and x_max there are even less.

So for getting a nice picture, the task is to get an average for the high interest values and to fill the gaps elsewhere.

I define my grid now. For each xx-yy pair, i want to have a color.

xx = np.linspace(x_min, x_max, gridsize) # array of x values
yy = np.linspace(y_min, y_max, gridsize) # array of y values
grid = np.array(np.meshgrid(xx, yy.T))
grid = grid.reshape(2, grid.shape[1]*grid.shape[2]).T

Why the strange shape? scipy.griddata wants a shape of (n, D).

Griddata calculates one value per point in the grid, by a predefined method. I choose "nearest" - empty grid points will be filled with values from the nearest neighbor. This looks as if the areas with less information have bigger cells (even if it is not the case). One could choose to interpolate "linear", then areas with less information look less sharp. Matter of taste, really.

points = np.array([x, y]).T # because griddata wants it that way
z_grid2 = griddata(points, z, grid, method='nearest')
# you get a 1D vector as result. Reshape to picture format!
z_grid2 = z_grid2.reshape(xx.shape[0], yy.shape[0])

And hop, we hand over to matplotlib to display the plot

fig = plt.figure(1, figsize=(10, 10))
ax1 = fig.add_subplot(111)
ax1.imshow(z_grid2, extent=[x_min, x_max,y_min, y_max,  ],
            origin='lower', cmap=cm.magma)
ax1.set_title("SVC: empty spots filled by nearest neighbours")
ax1.set_xlabel('log gamma')
ax1.set_ylabel('log C')
plt.show()

Around the pointy part of the V-Shape, you see I did a lot of calculations during my search for the sweet spot, whereas the less interesting parts almost everywhere else have a lower resolution.

I recently used requests_html library to solve this problem.

Their expanded documentation at readthedocs.io is pretty good (skip the annotated version at pypi.org). If your use case is basic, you are likely to have some success.

from requests_html import HTMLSession
session = HTMLSession()
response = session.request(method="get",url="www.google.com/")
response.html.render()

If you are having trouble rendering the data you need with response.html.render(), you can pass some javascript to the render function to render the particular js object you need. This is copied from their docs, but it might be just what you need:

If script is specified, it will execute the provided JavaScript at runtime. Example:

script = """
    () => {
        return {
            width: document.documentElement.clientWidth,
            height: document.documentElement.clientHeight,
            deviceScaleFactor: window.devicePixelRatio,
        }
    } 
"""

Returns the return value of the executed script, if any is provided:

>>> response.html.render(script=script)
{'width': 800, 'height': 600, 'deviceScaleFactor': 1}

In my case, the data I wanted were the arrays that populated a javascript plot but the data wasn't getting rendered as text anywhere in the html. Sometimes its not clear at all what the object names are of the data you want if the data is populated dynamically. If you can't track down the js objects directly from view source or inspect, you can type in "window" followed by ENTER in the debugger console in the browser (Chrome) to pull up a full list of objects rendered by the browser. If you make a few educated guesses about where the data is stored, you might have some luck finding it there. My graph data was under window.view.data in the console, so in the "script" variable passed to the .render() method quoted above, I used:

return {
    data: window.view.data
}

I think you may use the callback from a JSONP request or maybe just the pure JSON data using an external service but based on the output of javascript location.host that way:

$.getJSON( "//freegeoip.net/json/" + window.location.host + "?callback=?", function(data) {
    console.warn('Fetching JSON data...');
    // Log output to console
    console.info(JSON.stringify(data, null, 2));
});

I'll use this code for my personal needs, as first I was coming on this site for the same reason.

You may use another external service instead the one I'm using for my needs. A very nice list exist and contains tests done here https://stackoverflow.com/a/35123097/5778582

This problem:

$ brew install docker docker-machine
$ docker ps

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This apparently meant do the following:

$ docker-machine create default # default driver is apparently vbox:
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
$  brew cask install virtualbox
…
$ docker-machine create default 
# works this time
$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
$ eval "$(docker-machine env default)"
$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

It finally works.

You can use the “xhyve” driver if you don’t want to install virtual box. Also you can install the “docker app” (then run it) which apparently makes it so you don’t have to run some of the above. brew cask install docker then run the app, see the other answers. But apparently isn't necessary per se.

if you use Tomcat in your boot app here is org.apache.catalina.filters.RequestDumperFilter in a class path for you. (but it will not provide you "with exceptions in single place").

How to find elements by class

I'm having trouble parsing html elements with "class" attribute using Beautifulsoup.

You can easily find by one class, but if you want to find by the intersection of two classes, it's a little more difficult,

From the documentation (emphasis added):

If you want to search for tags that match two or more CSS classes, you should use a CSS selector:

css_soup.select("p.strikeout.body")
# [<p class="body strikeout"></p>]

To be clear, this selects only the p tags that are both strikeout and body class.

To find for the intersection of any in a set of classes (not the intersection, but the union), you can give a list to the class_ keyword argument (as of 4.1.2):

soup = BeautifulSoup(sdata)
class_list = ["stylelistrow"] # can add any other classes to this list.
# will find any divs with any names in class_list:
mydivs = soup.find_all('div', class_=class_list) 

Also note that findAll has been renamed from the camelCase to the more Pythonic find_all.

Yes; you can use return instead of exit. Its main purpose is to return from a shell function, but if you use it within a source-d script, it returns from that script.

As §4.1 "Bourne Shell Builtins" of the Bash Reference Manual puts it:

     return [n]

Cause a shell function to exit with the return value n. If n is not supplied, the return value is the exit status of the last command executed in the function. This may also be used to terminate execution of a script being executed with the . (or source) builtin, returning either n or the exit status of the last command executed within the script as the exit status of the script. Any command associated with the RETURN trap is executed before execution resumes after the function or script. The return status is non-zero if return is used outside a function and not during the execution of a script by . or source.

The compiler can't figure out what type to make the Dictionary, because it's not homogenous. You have values of different types. The only way to get around this is to make it a [String: Any], which will make everything clunky as all hell.

return [
    "title": title,
    "is_draft": isDraft,
    "difficulty": difficulty,
    "duration": duration,
    "cost": cost,
    "user_id": userId,
    "description": description,
    "to_sell": toSell,
    "images": [imageParameters, imageToDeleteParameters].flatMap { $0 }
] as [String: Any]

This is a job for a struct. It'll vastly simplify working with this data structure.

just as a .crt file is in .pem format, a .key file is also stored in .pem format. Assuming that the cert is the only thing in the .crt file (there may be root certs in there), you can just change the name to .pem. The same goes for a .key file. Which means of course that you can rename the .pem file to .key.

Which makes gtrig's answer the correct one. I just thought I'd explain why.

To bypass google's check, which is what you really want, simply remove the extensions from the file when you send it, and add them back after you download it. For example:

• tar czvf file.tar.gz directory
• mv file.tar.gz filetargz
• [send filetargz via gmail]
• [download filetargz]
• [rename filetargz to file.tar.gz and open]

Use below function

// Enable error reporting
ini_set('display_errors', 1);
//Report runtime errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
//error_reporting(E_ALL & ~E_NOTICE);
// Tell php where your custom php error log is
ini_set('error_log', 'php_error.log');

$dateTime=date("Y-m-d H:i:s");
$ip= $_SERVER['REMOTE_ADDR'];
$errorString="Error occured on time $dateTime by ip $ip";
$php_error_msg.=$errorString;
// Append the error message to the php-error log
//error_log($php_error_msg);
error_log("A custom error has been triggered",1,"email_address","From: email_address");

Above function will create a log in file php_error with proper description and email will be sent.

This will definately work for you.

If you already have a table pre_loaded_tbl with some data. You can use a trick to load the data into your table with following query

INSERT INTO TABLE tweet_table 
  SELECT  "my_data" AS my_column 
    FROM   pre_loaded_tbl 
   LIMIT   5;

Also please note that "my_data" is independent of any data in the pre_loaded_tbl. You can select any data and write any column name (here my_data and my_column). Hive does not require it to have same column name. However structure of select statement should be same as that of your tweet_table. You can use limit to determine how many times you can insert into the tweet_table.

However if you haven't' created any table, you will have to load the data using file copy or load data commands in above answers.

If you'd checked the results of stream.Read, you'd have seen that it hadn't read anything - because you haven't rewound the stream. (You could do this with stream.Position = 0;.) However, it's easier to just call ToArray:

settingsString = LocalEncoding.GetString(stream.ToArray());

(You'll need to change the type of stream from Stream to MemoryStream, but that's okay as it's in the same method where you create it.)

Alternatively - and even more simply - just use StringWriter instead of StreamWriter. You'll need to create a subclass if you want to use UTF-8 instead of UTF-16, but that's pretty easy. See this answer for an example.

I'm concerned by the way you're just catching Exception and assuming that it means something harmless, by the way - without even logging anything. Note that using statements are generally cleaner than writing explicit finally blocks.

In the current version of select2 you just need to add the attribute data-placeholder="A NICE PLACEHOLDER". select2 will automatically assign the placeholder. Please note: adding an empty <option></option> inside the select is still mandatory.

I had a need to open a special html file locally (by pressing Enter when the file is selected in the file explorer in Windows), either just for viewing the file or for editing it in a special online editor.

So I wanted to distinguish between these two options by holding down the Ctrl-key or not, while pressing Enter.

As you all have understood from all the answers here, this seems to be not really possible, but here is a way that mimics this behaviour in a way that was acceptable for me.

The way this works is like this:

If you hold down the Ctrl-key when opening the file then a keydown event will never fire in the javascript code. But a keyup event will fire (when you finally release the Ctrl-key). The code captures that.

The code also turns off keyevents (both keyup and keydown) as soon as one of them occurs. So if you press the Ctrl-key after the file has opened, nothing will happen.

window.onkeyup = up;
window.onkeydown = down;
function up(e) {
  if (e.key === 'F5') return; // if you want this to work also on reload with F5.

  window.onkeyup = null;
  window.onkeyup = null;
  if (e.key === 'Control') {
    alert('Control key was released. You must have held it down while opening the file, so we will now load the file into the editor.');
  }         
}
function down() {
  window.onkeyup = null;
  window.onkeyup = null;
}

I just resolved this for myself, so hope this helps. My project runs on GlassFish 4, Eclipse MARS, with JDK 1.8 and JavaEE 7.

Firstly, you can find javax.mail.jar in the extracted glassfish folder: glassfish4->glassfish->modules

Next, in Eclipse, Right Click on your project in the explorer and navigate the following: Properties->Java Build Path->Libraries->Add External JARs-> Go to the aforementioned folder to add javax.mail.jar

For a variable:

foo.h:

class foo
{
private:
    static int i;
};

foo.cpp:

int foo::i = 0;

This is because there can only be one instance of foo::i in your program. It's sort of the equivalent of extern int i in a header file and int i in a source file.

For a constant you can put the value straight in the class declaration:

class foo
{
private:
    static int i;
    const static int a = 42;
};

You can use the re.sub() function to remove these characters:

>>> import re
>>> re.sub("[^a-zA-Z]+", "", "ABC12abc345def")
'ABCabcdef'

re.sub(MATCH PATTERN, REPLACE STRING, STRING TO SEARCH)

• "[^a-zA-Z]+" - look for any group of characters that are NOT a-zA-z.
• "" - Replace the matched characters with ""

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

You should be able to access the INSERTED table and retrieve ID or table's primary key. Something similar to this example ...

CREATE TRIGGER [dbo].[after_update] ON [dbo].[MYTABLE]
AFTER UPDATE AS 
BEGIN
    DECLARE @id AS INT
    SELECT @id = [IdColumnName]
    FROM INSERTED

    UPDATE MYTABLE 
    SET mytable.CHANGED_ON = GETDATE(),
    CHANGED_BY=USER_NAME(USER_ID())
    WHERE [IdColumnName] = @id

Here's a link on MSDN on the INSERTED and DELETED tables available when using triggers: http://msdn.microsoft.com/en-au/library/ms191300.aspx

The answer shared by @mockinterface is correct. Although I would like to add my 2 cents to it.

If someone is using frameworks like scrapy the you will have to use /html/body//a[contains(@href,'com')][2]/@href along with get() like this:

response.xpath('//a[contains(@href,'com')][2]/@href').get()

Using Ellipsis

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),

Using Fade

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),

Using Clip

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),

Note:

If you are using Text inside a Row, you can put above Text inside Expanded like:

Expanded(
  child: AboveText(),
)

For me implementing a new library just because Safari cannot do it correctly is too much and a regex is overkill. Here is the oneliner:

console.log (new Date('2011-04-12'.replace(/-/g, "/")));

Try man perllocal or perldoc perllocal.

There is way to do that ;)

You would need a mapping provider for MySQL. That is an extra thing the Entity Framework needs to make the magic happen. This blog talks about other mapping providers besides the one Microsoft is supplying. I haven't found any mentionings of MySQL.

Not a big fun of updating user input, however considering your constraints...

public int[] removeDup(int[] nums) {
  Arrays.sort(nums);
  int x = 0;
  for (int i = 0; i < nums.length; i++) {
    if (i == 0 || nums[i] != nums[i - 1]) {
    nums[x++] = nums[i];
    }
  }
  return Arrays.copyOf(nums, x);
}

Array sort can be easily replaced with any nlog(n) algorithm.

Weird thing for me was that I had the provider:[], but the HTML tag that uses the provider was what was causing the error. I'm referring to the red box below:

It turns out I had two classes in different components with the same "employee-list.component.ts" filename and so the project compiled fine, but the references were all messed up.

Check "Getting a list of all subdirectories in the current directory".

Here's a Python 3 version:

import os

dir_list = next(os.walk('.'))[1]

print(dir_list)

Install Tidy2 plugin. I have Notepad++ v6.2.2, and Tidy2 works fine so far.

In C# :

public bool EhPalindromo(string text)
{
 var reverseText = string.Join("", text.ToLower().Reverse());
 return reverseText == text;
}

The AddRange method

aList.AddRange( anotherList );

I noticed creation of 'appcompat' library while creating new android project with ADT 22.6.2 version, even when the minSDK was set to 11 and targetSDK was set 19

This was happening because, in the new project template android is using some attributes that are from the support library. For instance if a new project was created with actionbar then in the menu's main.xml one could find app:showAsAction="never" which is from support library.

• If the app is targeted at android version 11 and above then one can change this attribute to android:showAsAction in menu's main.xml

• Also the default theme set could be "Theme.AppCompat.Light.DarkActionBar" as shown below (styles.xml)

  <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
         <!-- API 14 theme customizations can go here. -->
     </style> 
  

  In this case the parent theme in style.xml has to be changed to "android:style/Theme.Holo.Light.DarkActionBar"

• In addition to this if reference to Fragment,Fragments Manager from support library was made in the code of MainActivity.java, these have to appropriately changed to Fragment, FragmentManager of the SDK.

Here's how you should do it:

change_column :users, :admin, :boolean, :default => false

But some databases, like PostgreSQL, will not update the field for rows previously created, so make sure you update the field manaully on the migration too.

In your file.php of request ajax, can set value header.

<?php header('Access-Control-Allow-Origin: *'); //for all ?>

I have used a different USB cable and it started working. This is weird because the USB cable (which was not detected in android studio) was charging the phone. This made me feel like there was a problem on my Mac.

However changing the cable worked for me. Just check this option as well if you got stuck with this problem.

Set height and overflow:

html, body {margin: 0; height: 100%; overflow: hidden}

I suppose you could get a good guess by running top and looking for active processes using a lot of memory. Doing this programatically is harder---just look at the endless debates about the Linux OOM killer heuristics.

Swapping is a function of having more memory in active use than is installed, so it is usually hard to blame it on a single process. If it is an ongoing problem, the best solution is to install more memory, or make other systemic changes.

If by binary you mean bytes type, you can just use encode method of the string object that encodes your string as a bytes object using the passed encoding type. You just need to make sure you pass a proper encoding to encode function.

In [9]: "hello world".encode('ascii')                                                                                                                                                                       
Out[9]: b'hello world'

In [10]: byte_obj = "hello world".encode('ascii')                                                                                                                                                           

In [11]: byte_obj                                                                                                                                                                                           
Out[11]: b'hello world'

In [12]: byte_obj[0]                                                                                                                                                                                        
Out[12]: 104

Otherwise, if you want them in form of zeros and ones --binary representation-- as a more pythonic way you can first convert your string to byte array then use bin function within map :

>>> st = "hello world"
>>> map(bin,bytearray(st))
['0b1101000', '0b1100101', '0b1101100', '0b1101100', '0b1101111', '0b100000', '0b1110111', '0b1101111', '0b1110010', '0b1101100', '0b1100100']
 

Or you can join it:

>>> ' '.join(map(bin,bytearray(st)))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

Note that in python3 you need to specify an encoding for bytearray function :

>>> ' '.join(map(bin,bytearray(st,'utf8')))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

You can also use binascii module in python 2:

>>> import binascii
>>> bin(int(binascii.hexlify(st),16))
'0b110100001100101011011000110110001101111001000000111011101101111011100100110110001100100'

hexlify return the hexadecimal representation of the binary data then you can convert to int by specifying 16 as its base then convert it to binary with bin.

Matrix operations using SIMD instructions is probably faster than compiler generated code.

You could also use a static class, such as a Config class or something along those lines...

public static class Config
{
    public static readonly string SomeValue = "blah";
}

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var textLbl: UILabel!

    var containerView = UIView()
    var loadingView = UIView()
    var activityIndicator = UIActivityIndicatorView()

    override func viewDidLoad() {
        super.viewDidLoad()

        let _  = Timer.scheduledTimer(withTimeInterval: 10, repeats: false) { (_) in
            self.textLbl.text = "Stop ActivitiIndicator"
            self.activityIndicator.stopAnimating()
            self.containerView.removeFromSuperview()
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    @IBAction func palyClicked(sender: AnyObject){

        containerView.frame = self.view.frame
        containerView.backgroundColor = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.3)
        self.view.addSubview(containerView)

        loadingView.frame = CGRect(x: 0, y: 0, width: 80, height: 80)
        loadingView.center = self.view.center
        loadingView.backgroundColor = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.5)
        loadingView.clipsToBounds = true
        loadingView.layer.cornerRadius = 10
        containerView.addSubview(loadingView)

        activityIndicator.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
        activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.whiteLarge
        activityIndicator.center = CGPoint(x:loadingView.frame.size.width / 2, y:loadingView.frame.size.height / 2);
        activityIndicator.startAnimating()
        loadingView.addSubview(activityIndicator)

    }
}

You can try the following code:

unsigned char a = 0;
unsigned char b = 0xff;
cout << hex << "a is " << int(a) << "; b is " << int(b) << endl;
cout << hex
     <<   "a is " << setfill('0') << setw(2) << int(a)
     << "; b is " << setfill('0') << setw(2) << int(b)
     << endl;
cout << hex << uppercase
     <<   "a is " << setfill('0') << setw(2) << int(a)
     << "; b is " << setfill('0') << setw(2) << int(b)
     << endl;

Output:

a is 0; b is ff

a is 00; b is ff

a is 00; b is FF

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:

• If the object I'm creating conceptually holds the values I'm passing in the constructor (e.g. containers, POD structs, atomics, smart pointers etc.), then I'm using the braces.
• If the constructor resembles a normal function call (it performs some more or less complex operations that are parametrized by the arguments) then I'm using the normal function call syntax.
• For default initialization I always use curly braces.
  For one, that way I'm always sure that the object gets initialized irrespective of whether it e.g. is a "real" class with a default constructor that would get called anyway or a builtin / POD type. Second it is - in most cases - consistent with the first rule, as a default initialized object often represents an "empty" object.

In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).

It e.g. fits nicely with standard library-types like std::vector:

vector<int> a{10,20};   //Curly braces -> fills the vector with the arguments

vector<int> b(10,20);   //Parentheses -> uses arguments to parametrize some functionality,                          
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.

vector<int> d{};      //empty braces -> default constructs vector, which is equivalent
                      //to a vector that is filled with zero elements
