In my case the problem was that many scikit functions return numpy arrays, which are devoid of pandas index. So there was an index mismatch when I used those numpy arrays to build new DataFrames and then I tried to mix them with the original data.

If you are using Netbeans, try to hit the Clean and Build button, let it do the thing and try again. Worked for me!

How do I create a new column with Groupby().Sum()?

There are two ways - one straightforward and the other slightly more interesting.

Everybody's Favorite: GroupBy.transform() with 'sum'

@Ed Chum's answer can be simplified, a bit. Call DataFrame.groupby rather than Series.groupby. This results in simpler syntax.

# The setup.
df[['Date', 'Data3']]

         Date  Data3
0  2015-05-08      5
1  2015-05-07      8
2  2015-05-06      6
3  2015-05-05      1
4  2015-05-08     50
5  2015-05-07    100
6  2015-05-06     60
7  2015-05-05    120

df.groupby('Date')['Data3'].transform('sum')

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Data3, dtype: int64 

It's a tad faster,

df2 = pd.concat([df] * 12345)

%timeit df2['Data3'].groupby(df['Date']).transform('sum')
%timeit df2.groupby('Date')['Data3'].transform('sum')

10.4 ms ± 367 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
8.58 ms ± 559 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Unconventional, but Worth your Consideration: GroupBy.sum() + Series.map()

I stumbled upon an interesting idiosyncrasy in the API. From what I tell, you can reproduce this on any major version over 0.20 (I tested this on 0.23 and 0.24). It seems like you consistently can shave off a few milliseconds of the time taken by transform if you instead use a direct function of GroupBy and broadcast it using map:

df.Date.map(df.groupby('Date')['Data3'].sum())

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Date, dtype: int64

Compare with

df.groupby('Date')['Data3'].transform('sum')

0     55
1    108
2     66
3    121
4     55
5    108
6     66
7    121
Name: Data3, dtype: int64

My tests show that map is a bit faster if you can afford to use the direct GroupBy function (such as mean, min, max, first, etc). It is more or less faster for most general situations upto around ~200 thousand records. After that, the performance really depends on the data.

(Left: v0.23, Right: v0.24)

Nice alternative to know, and better if you have smaller frames with smaller numbers of groups. . . but I would recommend transform as a first choice. Thought this was worth sharing anyway.

Benchmarking code, for reference:

import perfplot

perfplot.show(
    setup=lambda n: pd.DataFrame({'A': np.random.choice(n//10, n), 'B': np.ones(n)}),
    kernels=[
        lambda df: df.groupby('A')['B'].transform('sum'),
        lambda df:  df.A.map(df.groupby('A')['B'].sum()),
    ],
    labels=['GroupBy.transform', 'GroupBy.sum + map'],
    n_range=[2**k for k in range(5, 20)],
    xlabel='N',
    logy=True,
    logx=True
)

Thread is a class, not an instance; currentThread() is a static method that returns the Thread instance corresponding to the calling thread.

Use (2). interrupt() is a bit brutal for normal use.

Here is a simple interpretation about your problem:

== (equal to) used to evaluate arithmetic expression

where as

equals() method used to compare string

Therefore, it its better to use == for numeric operations & equals() method for String related operations. So, for comparison of objects the equals() method would be right choice.

The simplest solution is:

git clone --recursive [email protected]:name/repo.git

Then cd in the repo directory and:

git submodule update --init
git submodule foreach -q --recursive 'git checkout $(git config -f $toplevel/.gitmodules submodule.$name.branch || echo master)'
git config --global status.submoduleSummary true

You either need to create an object of type Beta in the Alpha class or its method

Like you do here in the Main Beta cBeta = new Beta();

If you want to use the variable you create in your Main then you have to parse it to cAlpha as a parameter by making the Alpha constructor look like

public class Alpha 
{

    Beta localInstance;

    public Alpha(Beta _beta)
    {
        localInstance = _beta;
    }


     public void DoSomethingAlpha() 
     {
          localInstance.DoSomethingAlpha();     
     }
}

HTML
<img id="close" className="fa fa-close" src="" alt="" title="Close Me" />

CSS
#close[title]:hover:after {
  color: red;
  content: attr(title);
  position: absolute;
  left: 50px;
}

I installed using the command:

./configure --prefix=/usr       \
            --enable-shared     \
            --with-system-expat \
            --with-system-ffi   \
            --enable-unicode=ucs4 &&

make

Now, as the root user:

make install &&
chmod -v 755 /usr/lib/libpython2.7.so.1.0

Then I tried to execute python and got the error:

/usr/local/bin/python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

Then, I logged out from root user and again tried to execute the Python and it worked successfully.

This often occurs when you build software in RHEL 7 and try to run on RHEL 6.

To update GLIBC to any version, simply download the package from

https://ftp.gnu.org/gnu/libc/

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. sudo make install
8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

Then try to run your software, glibc-2.14 should be linked.

Instead of using the full plugin name (with groupId) like described in Bartosz's answer, you could add

<pluginGroups>
    <pluginGroup>org.springframework.boot</pluginGroup>
</pluginGroups>

to your .m2/settings.xml.

This is not an answer, really and I would have entered it as a comment had the question not been locked. This answers the question:

Why would you want it?

Assume you have a table with the sequence as the primary key and the sequence is generated by an insert trigger. If you wanted to have the sequence available for subsequent updates to the record, you need to have a way to extract that value.

In order to make sure you get the right one, you might want to wrap the INSERT and RonK's query in a transaction.

RonK's Query:

select MY_SEQ_NAME.currval from DUAL;

In the above scenario, RonK's caveat does not apply since the insert and update would happen in the same session.

create_function did not work for me inside a class. I had to use call_user_func.

<?php

class Dispatcher {
    //Added explicit callback declaration.
    var $callback;

    public function Dispatcher( $callback ){
         $this->callback = $callback;
    }

    public function asynchronous_method(){
       //do asynch stuff, like fwrite...then, fire callback.
       if ( isset( $this->callback ) ) {
            if (function_exists( $this->callback )) call_user_func( $this->callback, "File done!" );
        }
    }

}

Then, to use:

<?php 
include_once('Dispatcher.php');
$d = new Dispatcher( 'do_callback' );
$d->asynchronous_method();

function do_callback( $data ){
   print 'Data is: ' .  $data .  "\n";
}
?>

[Edit] Added a missing parenthesis. Also, added the callback declaration, I prefer it that way.

You can convert the int back to an enumeration member with a simple cast, and then call ToString():

int value = GetValueFromDb();
var enumDisplayStatus = (EnumDisplayStatus)value;
string stringValue = enumDisplayStatus.ToString();

I use mysql workbench to do the same job.

1. create new schema
2. open newly created schema
3. right click on "Tables" and select "Table Data Import Wizard"
4. give the csv file path and table name and finally configure your column type because the wizard set default column type based on their values.

Note: take a look at mysql workbench's log file for any errors by using "tail -f [mysqlworkbenchpath]/log/wb*.log"

Here It is actually returning tuple.

If you execute this code in Python 3:

def get():
    a = 3
    b = 5
    return a,b
number = get()
print(type(number))
print(number)

Output :

<class 'tuple'>
(3, 5)

But if you change the code line return [a,b] instead of return a,b and execute :

def get():
    a = 3
    b = 5
    return [a,b]
number = get()
print(type(number))
print(number)

Output :

<class 'list'>
[3, 5]

It is only returning single object which contains multiple values.

There is another alternative to return statement for returning multiple values, use yield( to check in details see this What does the "yield" keyword do in Python?)

Sample Example :

def get():
    for i in range(5):
        yield i
number = get()
print(type(number))
print(number)
for i in number:
    print(i)

Output :

<class 'generator'>
<generator object get at 0x7fbe5a1698b8>
0
1

3
4

In regards to your error and what's missing in your code. m is a name which is not defined for getmd5() function.

No offence, I know you are a beginner, but your code is all over the place. Let's look at your issues one by one :)

First, you are not using hashlib.md5.hexdigest() method correctly. Please refer explanation on hashlib functions in Python Doc Library. The correct way to return MD5 for provided string is to do something like this:

>>> import hashlib
>>> hashlib.md5("filename.exe").hexdigest()
'2a53375ff139d9837e93a38a279d63e5'

However, you have a bigger problem here. You are calculating MD5 on a file name string, where in reality MD5 is calculated based on file contents. You will need to basically read file contents and pipe it though MD5. My next example is not very efficient, but something like this:

>>> import hashlib
>>> hashlib.md5(open('filename.exe','rb').read()).hexdigest()
'd41d8cd98f00b204e9800998ecf8427e'

As you can clearly see second MD5 hash is totally different from the first one. The reason for that is that we are pushing contents of the file through, not just file name.

A simple solution could be something like that:

# Import hashlib library (md5 method is part of it)
import hashlib

# File to check
file_name = 'filename.exe'

# Correct original md5 goes here
original_md5 = '5d41402abc4b2a76b9719d911017c592'  

# Open,close, read file and calculate MD5 on its contents 
with open(file_name) as file_to_check:
    # read contents of the file
    data = file_to_check.read()    
    # pipe contents of the file through
    md5_returned = hashlib.md5(data).hexdigest()

# Finally compare original MD5 with freshly calculated
if original_md5 == md5_returned:
    print "MD5 verified."
else:
    print "MD5 verification failed!."

Please look at the post Python: Generating a MD5 checksum of a file. It explains in detail a couple of ways how it can be achieved efficiently.

Best of luck.

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

In addition, If you know your code should not work if object is null, you can throw exception by using Optional.orElseThrow

String nullName = null;

String name = Optional.ofNullable(nullName)
                      .orElseThrow(NullPointerException::new);
                   // .orElseThrow(CustomException::new);

Adding to @David Roussel answer, classes may be loaded by multiple class loaders.

Lets understand how class loader works.

From javin paul blog in javarevisited :

ClassLoader follows three principles.

Delegation principle

A class is loaded in Java, when its needed. Suppose you have an application specific class called Abc.class, first request of loading this class will come to Application ClassLoader which will delegate to its parent Extension ClassLoader which further delegates to Primordial or Bootstrap class loader

• Bootstrap ClassLoader is responsible for loading standard JDK class files from rt.jar and it is parent of all class loaders in Java. Bootstrap class loader don't have any parents.

• Extension ClassLoader delegates class loading request to its parent, Bootstrap and if unsuccessful, loads class form jre/lib/ext directory or any other directory pointed by java.ext.dirs system property

• System or Application class loader and it is responsible for loading application specific classes from CLASSPATH environment variable, -classpath or -cp command line option, Class-Path attribute of Manifest file inside JAR.

• Application class loader is a child of Extension ClassLoader and its implemented by sun.misc.Launcher$AppClassLoader class.

NOTE: Except Bootstrap class loader, which is implemented in native language mostly in C, all Java class loaders are implemented using java.lang.ClassLoader.

Visibility Principle

According to visibility principle, Child ClassLoader can see class loaded by Parent ClassLoader but vice-versa is not true.

Uniqueness Principle

According to this principle a class loaded by Parent should not be loaded by Child ClassLoader again

There only two things that MapReduce does NATIVELY: Sort and (implemented by sort) scalable GroupBy.

Most of applications and Design Patterns over MapReduce are built over these two operations, which are provided by shuffle and sort.

I had a case where I had to fetch the first result of a very big Cartesian product. And it would take ages despite I only wanted one item. The problem was that it had to iterate through many unwanted results before finding a correct one because of the order of the results. So if I had 10 lists of 50 elements and the first element of the two first lists were incompatible, it had to iterate through the Cartesian product of the last 8 lists despite that they would all get rejected.

This implementation enables to test a result before it includes one item from each list. So when I check that an element is incompatible with the already included elements from the previous lists, I immediately go to the next element of the current list rather than iterating through all products of the following lists.

set @StartDate = '10/01/2012 08:40:18.000'

-CAST(CONVERT(varchar(23),@StartDate,121)AS DATETIME),8) AS TimeDiff

do not change the props directly in components.if you need change it set a new property like this:

data () {
    return () {
        listClone: this.list
    }
}

And change the value of listClone.

Normally views are not parameterized. But you could always inject some parameters. For example using session context:

CREATE VIEW my_view
AS
SELECT *
FROM tab
WHERE num = SESSION_CONTEXT(N'my_num');

Invocation:

EXEC sp_set_session_context 'my_num', 1; 
SELECT * FROM my_view;

And another:

EXEC sp_set_session_context 'my_num', 2; 
SELECT * FROM my_view;

DBFiddle Demo

The same is applicable for Oracle (of course syntax for context function is different).

I originally used the solution that @Mrchief for years (it works great). But when when I added Swagger to my project for API documentation my end point was NOT showing up.

It took me a while, but this is what I came up with. It works with Swagger, and your API method signatures look cleaner:

In the end you can do:

    // GET: /api/values/1,2,3,4 

    [Route("api/values/{ids}")]
    public IHttpActionResult GetIds(int[] ids)
    {
        return Ok(ids);
    }

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Allow WebApi to Use a Custom Parameter Binding
        config.ParameterBindingRules.Add(descriptor => descriptor.ParameterType == typeof(int[]) && descriptor.ActionDescriptor.SupportedHttpMethods.Contains(HttpMethod.Get)
                                                           ? new CommaDelimitedArrayParameterBinder(descriptor)
                                                           : null);

        // Allow ApiExplorer to understand this type (Swagger uses ApiExplorer under the hood)
        TypeDescriptor.AddAttributes(typeof(int[]), new TypeConverterAttribute(typeof(StringToIntArrayConverter)));

        // Any existing Code ..

    }
}

Create a new class: CommaDelimitedArrayParameterBinder.cs

public class CommaDelimitedArrayParameterBinder : HttpParameterBinding, IValueProviderParameterBinding
{
    public CommaDelimitedArrayParameterBinder(HttpParameterDescriptor desc)
        : base(desc)
    {
    }

    /// <summary>
    /// Handles Binding (Converts a comma delimited string into an array of integers)
    /// </summary>
    public override Task ExecuteBindingAsync(ModelMetadataProvider metadataProvider,
                                             HttpActionContext actionContext,
                                             CancellationToken cancellationToken)
    {
        var queryString = actionContext.ControllerContext.RouteData.Values[Descriptor.ParameterName] as string;

        var ints = queryString?.Split(',').Select(int.Parse).ToArray();

        SetValue(actionContext, ints);

        return Task.CompletedTask;
    }

    public IEnumerable<ValueProviderFactory> ValueProviderFactories { get; } = new[] { new QueryStringValueProviderFactory() };
}

Create a new class: StringToIntArrayConverter.cs

public class StringToIntArrayConverter : TypeConverter
{
    public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
    {
        return sourceType == typeof(string) || base.CanConvertFrom(context, sourceType);
    }
}

Notes:

• https://stackoverflow.com/a/47123965/862011 pointed me in the right direction
• Swagger was only failing to pick my comma delimited end points when using the [Route] attribute

try this code ['12','34','35','231']*","

will give you result "12,34,35,231"

I hope this is the result you, let me know

  $("#select_all").live("click", function(){
            $("input").prop("checked", $(this).prop("checked"));
    }
  });

For what it's worth, I hit a similar error in XCode 9.0.1. I tried uninstalling and reinstalling all my certs, but when I reinstalled, they seemed to remember the trust setting I had previously. What ended up working for me (it seems) was turning off the 'Always Trust' setting of the "Apple Worldwide Developer Relations Certification Authority" cert followed by a reboot. What a cryptic issue!

$("#btnAddProfile").html('Save').button('refresh');

It looks that whatever that text is containing some characters which cannot be converted to integer like space, letters, special characters etc. Check what is coming through dropdown as below

lvTwoOrMoreOptions.SelectedItems[0].Text.ToString();

and see if that is the case.

One liner:

location.search.replace('?','').split('&').reduce(function(s,c){var t=c.split('=');s[t[0]]=t[1];return s;},{})

In swift language we can set content mode of UIImage view like following as:

let newImgThumb = UIImageView(frame: CGRect(x: 10, y: 10, width: 100, height: 100))
newImgThumb.contentMode = .scaleAspectFit

Make sure you add both Jackson jars to classpath:

• jackson-core-asl-x.jar
• jackson-mapper-asl-x.jar

Also, you must have the following in your Spring xml file:

<mvc:annotation-driven />

There are several solutions depending on what you need...

If you want to add a custom header (or set of headers) to an individual request then just add the headers property:

// Request with custom header
$.ajax({
    url: 'foo/bar',
    headers: { 'x-my-custom-header': 'some value' }
});

If you want to add a default header (or set of headers) to every request then use $.ajaxSetup():

$.ajaxSetup({
    headers: { 'x-my-custom-header': 'some value' }
});

// Sends your custom header
$.ajax({ url: 'foo/bar' });

// Overwrites the default header with a new header
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });

If you want to add a header (or set of headers) to every request then use the beforeSend hook with $.ajaxSetup():

$.ajaxSetup({
    beforeSend: function(xhr) {
        xhr.setRequestHeader('x-my-custom-header', 'some value');
    }
});

// Sends your custom header
$.ajax({ url: 'foo/bar' });

// Sends both custom headers
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });

Edit (more info): One thing to be aware of is that with ajaxSetup you can only define one set of default headers and you can only define one beforeSend. If you call ajaxSetup multiple times, only the last set of headers will be sent and only the last before-send callback will execute.

It's 2018 now, and Python have already evolve to the __future__ long time ago. So how about using the amazing pathlib coming with Python 3.4 to accomplish the task instead of struggling with os, os.path, glob, shutil, etc.

So we have 3 paths here (possibly duplicated):

• mod_path: which is the path of the simple helper script
• src_path: which contains a couple of template files waiting to be copied.
• cwd: current directory, the destination of those template files.

and the problem is: we don't have the full path of src_path, only know it's relative path to the mod_path.

Now let's solve this with the the amazing pathlib:

# Hope you don't be imprisoned by legacy Python code :)
from pathlib import Path

# `cwd`: current directory is straightforward
cwd = Path.cwd()

# `mod_path`: According to the accepted answer and combine with future power
# if we are in the `helper_script.py`
mod_path = Path(__file__).parent
# OR if we are `import helper_script`
mod_path = Path(helper_script.__file__).parent

# `src_path`: with the future power, it's just so straightforward
relative_path_1 = 'same/parent/with/helper/script/'
relative_path_2 = '../../or/any/level/up/'
src_path_1 = (mod_path / relative_path_1).resolve()
src_path_2 = (mod_path / relative_path_2).resolve()

In the future, it just that simple. :D

Moreover, we can select and check and copy/move those template files with pathlib:

if src_path != cwd:
    # When we have different types of files in the `src_path`
    for template_path in src_path.glob('*.ini'):
        fname = template_path.name
        target = cwd / fname
        if not target.exists():
            # This is the COPY action
            with target.open(mode='wb') as fd:
                fd.write(template_path.read_bytes())
            # If we want MOVE action, we could use:
            # template_path.replace(target)

I think that they are often not "versus", but you can combine them. I also think that oftentimes, the words you mention are just buzzwords. There are few people who actually know what "object-oriented" means, even if they are the fiercest evangelists of it.

For Anaconda3, simply install in Anaconda Navigator:

Direct answer:

• Use a = operator

We can use the public member function std::vector::operator= of the container std::vector for assigning values from a vector to another.

• Use a constructor function

Besides, a constructor function also makes sense. A constructor function with another vector as parameter(e.g. x) constructs a container with a copy of each of the elements in x , in the same order.

Caution:

• Do not use std::vector::swap

std::vector::swap is not copying a vector to another, it is actually swapping elements of two vectors, just as its name suggests. In other words, the source vector to copy from is modified after std::vector::swap is called, which is probably not what you are expected.

• Deep or shallow copy?

If the elements in the source vector are pointers to other data, then a deep copy is wanted sometimes.

According to wikipedia:

A deep copy, meaning that fields are dereferenced: rather than references to objects being copied, new copy objects are created for any referenced objects, and references to these placed in B.

Actually, there is no currently a built-in way in C++ to do a deep copy. All of the ways mentioned above are shallow. If a deep copy is necessary, you can traverse a vector and make copy of the references manually. Alternatively, an iterator can be considered for traversing. Discussion on iterator is beyond this question.

You say that your module-info.java contains

module myModule {}

That means it declares a module called myModule, not com.pantech.myModule. Pointing this from the command format:

 -m <module-name>/<main-class>

In C, you can use int atoi (const char * str),

Parses the C-string str interpreting its content as an integral number, which is returned as a value of type int.

Here is a one line lambda that also works:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Input:

searchfor = ['og', 'at']

df = pd.DataFrame([('cat', 1000.0), ('hat', 2000000.0), ('dog', 1000.0), ('fog', 330000.0),('pet', 330000.0)], columns=['col1', 'col2'])

   col1  col2
0   cat 1000.0
1   hat 2000000.0
2   dog 1000.0
3   fog 330000.0
4   pet 330000.0

Apply Lambda:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Output:

    col1    col2        TrueFalse
0   cat     1000.0      1
1   hat     2000000.0   1
2   dog     1000.0      1
3   fog     330000.0    1
4   pet     330000.0    0

You can check if it's not set (or empty) in a number of ways.

if (!$var){ }

Or:

if ($var === null){ } // This checks if the variable, by type, IS null.

Or:

if (empty($var)){ }

You can check if it's declared with:

if (!isset($var)){ }

Take note that PHP interprets 0 (integer) and "" (empty string) and false as "empty" - and dispite being different types, these specific values are by PHP considered the same. It doesn't matter if $var is never set/declared or if it's declared as $var = 0 or $var = "". So often you compare by using the === operator which compares with respect to data type. If $var is 0 (integer), $var == "" or $var == false will validate, but $var === "" or $var === false will not.

Why not using Cakes Response Class? You can set the status code of the response simply by this:

$this->response->statusCode(200);

Then just render a file with the error message, which suits best with JSON.

If you're using Python 2.5, this won't work, but for people using 2.6 or 2.7, try

from __future__ import print_function

print("abcd", end='')
print("efg")

results in

abcdefg

For those using 3.x, this is already built-in.

Similar to several answers like Alex V's and NDavis, but none of them are quite the same.

When already in the branch in question

Using:

git diff master...

Which combines several features:

• it's super short
• shows the actual changes

Update:

This should probably be git diff master, but also this shows the diff, not the commits as the question specified.

The zip() function in Python 3 returns an iterator. That is the reason why when you print test1 you get - <zip object at 0x1007a06c8>. From documentation -

Make an iterator that aggregates elements from each of the iterables.

But once you do - list(test1) - you have exhausted the iterator. So after that anytime you do list(test1) would only result in empty list.

In case of test2, you have already created the list once, test2 is a list, and hence it will always be that list.

This is another way of viewing definition of stored procedure

SELECT OBJECT_DEFINITION (OBJECT_ID(N'Your_SP'))

One problem here is that your method expects int values while you are passing string from ajax call. Try to change it to string and parse inside the webmethod if necessary :

[System.Web.Services.WebMethod]
public static string AddTo_Cart(string quantity, string itemId)
{
    //parse parameters here
    SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
    return "Add";
}

Edit : or Pass int parameters from ajax call.

Make sure you are clicking on the specific Resource first in the Stages tree, as that will populate a URL with the full path to the resource (rather than just the root path):

I found mongo-connector useful. It is form Mongo Labs (MongoDB Inc.) and can be used now with Elasticsearch 2.x

Elastic 2.x doc manager: https://github.com/mongodb-labs/elastic2-doc-manager

mongo-connector creates a pipeline from a MongoDB cluster to one or more target systems, such as Solr, Elasticsearch, or another MongoDB cluster. It synchronizes data in MongoDB to the target then tails the MongoDB oplog, keeping up with operations in MongoDB in real-time. It has been tested with Python 2.6, 2.7, and 3.3+. Detailed documentation is available on the wiki.

Another option is to add another tag with flex: auto style in between your tags that you want to fill in the remaining space.

https://jsfiddle.net/tsey5qu4/

The HTML:

<div class="parent">
  <div class="left">Left</div>
  <div class="fill-remaining-space"></div>
  <div class="right">Right</div>
</div>

The CSS:

.fill-remaining-space {
  flex: auto;
}

This is equivalent to flex: 1 1 auto, which absorbs any extra space along the main axis.

UPDATE table1 SET col_a = 'newvalue'

Add a WHERE condition if you want to only update some of the rows.

Starting from material components android 1.2.0-alpha01, you have slider component

ex:

<com.google.android.material.slider.Slider

        android:layout_height="wrap_content"
        android:valueFrom="20f"
        android:valueTo="70f"
        android:stepSize="10" />

Use ChartNew.js instead of Chart.js

...

So, I have re-worked Chart.js. Most of the changes, are associated to requests in "GitHub" issues of Chart.js.

And here is a sample http://jsbin.com/lakiyu/2/edit

var newopts = {
    inGraphDataShow: true,
    inGraphDataRadiusPosition: 2,
    inGraphDataFontColor: 'white'
}
var pieData = [
    {
        value: 30,
        color: "#F38630",
    },
    {
       value: 30,
       color: "#F34353",
    },
    {
        value: 30,
        color: "#F34353",
    }
]
var pieCtx = document.getElementById('pieChart').getContext('2d');
new Chart(pieCtx).Pie(pieData, newopts);

It even provides a GUI editor http://charts.livegap.com/

So sweet.

You can load an XML document into an XMLType, then query it, e.g.:

DECLARE
  x XMLType := XMLType(
    '<?xml version="1.0" ?> 
<person>
   <row>
       <name>Tom</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
   <row>
       <name>Jim</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
</person>');
BEGIN
  FOR r IN (
    SELECT ExtractValue(Value(p),'/row/name/text()') as name
          ,ExtractValue(Value(p),'/row/Address/State/text()') as state
          ,ExtractValue(Value(p),'/row/Address/City/text()') as city
    FROM   TABLE(XMLSequence(Extract(x,'/person/row'))) p
    ) LOOP
    -- do whatever you want with r.name, r.state, r.city
  END LOOP;
END;

You can do an http DELETE via a URL like /users/1/roles/2. That would be the most RESTful way to do it.

Otherwise I guess you can just pass the user id as part of the query params? Something like

$http.delete('/roles/' + roleid, {params: {userId: userID}}).then...

Just add this android:inputType="textMultiLine" in XML file on relevant field.

You are looking for map_keys, with it you can write things like

BOOST_FOREACH(const key_t key, the_map | boost::adaptors::map_keys)
{
  // do something with key
}

On my Ubuntu machine, I can see the output at /var/log/syslog.

On a RHEL/CentOS machine, the output is found in /var/log/messages.

This is controlled by the rsyslog service, so if this is disabled for some reason you may need to start it with systemctl start rsyslog.

As noted by others, your syslog() output would be logged by the /var/log/syslog file.
You can see system, user, and other logs at /var/log.

For more details: here's an interesting link.

formatDate is the function you can call it and pass the date you want to format to dd/mm/yyyy

var unformatedDate = new Date("2017-08-10 18:30:00");_x000D_
 _x000D_
$("#hello").append(formatDate(unformatedDate));_x000D_
function formatDate(nowDate) {_x000D_
 return nowDate.getDate() +"/"+ (nowDate.getMonth() + 1) + '/'+ nowDate.getFullYear();_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="hello">_x000D_
_x000D_
_x000D_
</div>

You can build a nice tree of dicts of dicts like this:

import collections

def Tree():
    return collections.defaultdict(Tree)

It might not be exactly what you want but it's quite useful! Values are saved only in the leaf nodes. Here is an example of how it works:

>>> t = Tree()
>>> t
defaultdict(<function tree at 0x2142f50>, {})
>>> t[1] = "value"
>>> t[2][2] = "another value"
>>> t
defaultdict(<function tree at 0x2142f50>, {1: 'value', 2: defaultdict(<function tree at 0x2142f50>, {2: 'another value'})}) 

For more information take a look at the gist.

I guess it should be readability ;)

CROSS APPLY will be somewhat unique for people reading to tell them that a UDF is being used which will be applied to each row from the table on the left.

Ofcourse, there are other limitations where a CROSS APPLY is better used than JOIN which other friends have posted above.

adjust video start and end time when using the video tag in html5;

where left of comma is start time in seconds, right of comma is end time in seconds. drop the comma and end time to effect the start time only.

To get started, you should download the source code from Github, by following the instructions here (you'll need Bazel and a recent version of GCC).

The C++ API (and the backend of the system) is in tensorflow/core. Right now, only the C++ Session interface, and the C API are being supported. You can use either of these to execute TensorFlow graphs that have been built using the Python API and serialized to a GraphDef protocol buffer. There is also an experimental feature for building graphs in C++, but this is currently not quite as full-featured as the Python API (e.g. no support for auto-differentiation at present). You can see an example program that builds a small graph in C++ here.

The second part of the C++ API is the API for adding a new OpKernel, which is the class containing implementations of numerical kernels for CPU and GPU. There are numerous examples of how to build these in tensorflow/core/kernels, as well as a tutorial for adding a new op in C++.

This is a well-known nuisance when posting multiline commands in R. (You can get different behavior when you source() a script to when you copy-and-paste the lines, both with multiline and comments)

Rule: always put the dangling '+' at the end of a line so R knows the command is unfinished:

ggplot(...) + geom_whatever1(...) +
  geom_whatever2(...) +
  stat_whatever3(...) +
  geom_title(...) + scale_y_log10(...)

Don't put the dangling '+' at the start of the line, since that tickles the error:

Error in "+ geom_whatever2(...) invalid argument to unary operator"

And obviously don't put dangling '+' at both end and start since that's a syntax error.

So, learn a habit of being consistent: always put '+' at end-of-line.

cf. answer to "Split code over multiple lines in an R script"

Easiest way is to select it from xml as follows,

<menu>
   <group android:checkableBehavior="single">
         <item
              android:checked="true"
              android:id="@+id/nav_home"
              android:icon="@drawable/nav_home"
              android:title="@string/main_screen_title_home" />

Note the line android:checked="true"

Here's an utility that rounds (instead of truncating) a double to specified number of decimal places.

For example:

round(200.3456, 2); // returns 200.35

Original version; watch out with this

public static double round(double value, int places) {
    if (places < 0) throw new IllegalArgumentException();

    long factor = (long) Math.pow(10, places);
    value = value * factor;
    long tmp = Math.round(value);
    return (double) tmp / factor;
}

This breaks down badly in corner cases with either a very high number of decimal places (e.g. round(1000.0d, 17)) or large integer part (e.g. round(90080070060.1d, 9)). Thanks to Sloin for pointing this out.

I've been using the above to round "not-too-big" doubles to 2 or 3 decimal places happily for years (for example to clean up time in seconds for logging purposes: 27.987654321987 -> 27.99). But I guess it's best to avoid it, since more reliable ways are readily available, with cleaner code too.

So, use this instead

(Adapted from this answer by Louis Wasserman and this one by Sean Owen.)

public static double round(double value, int places) {
    if (places < 0) throw new IllegalArgumentException();

    BigDecimal bd = BigDecimal.valueOf(value);
    bd = bd.setScale(places, RoundingMode.HALF_UP);
    return bd.doubleValue();
}

Note that HALF_UP is the rounding mode "commonly taught at school". Peruse the RoundingMode documentation, if you suspect you need something else such as Bankers’ Rounding.

Of course, if you prefer, you can inline the above into a one-liner:
new BigDecimal(value).setScale(places, RoundingMode.HALF_UP).doubleValue()

And in every case

Always remember that floating point representations using float and double are inexact. For example, consider these expressions:

999199.1231231235 == 999199.1231231236 // true
1.03 - 0.41 // 0.6200000000000001

For exactness, you want to use BigDecimal. And while at it, use the constructor that takes a String, never the one taking double. For instance, try executing this:

System.out.println(new BigDecimal(1.03).subtract(new BigDecimal(0.41)));
System.out.println(new BigDecimal("1.03").subtract(new BigDecimal("0.41")));

Some excellent further reading on the topic:

• Item 48: "Avoid float and double if exact answers are required" in Effective Java (2nd ed) by Joshua Bloch
• What Every Programmer Should Know About Floating-Point Arithmetic

If you wanted String formatting instead of (or in addition to) strictly rounding numbers, see the other answers.

Specifically, note that round(200, 0) returns 200.0. If you want to output "200.00", you should first round and then format the result for output (which is perfectly explained in Jesper's answer).

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

If (when the file doesn't exist) you want to create it as empty, the simplest approach is

with open(thepath, 'a'): pass

(in Python 2.6 or better; in 2.5, this requires an "import from the future" at the top of your module).

If, on the other hand, you want to leave the file alone if it exists, but put specific non-empty contents there otherwise, then more complicated approaches based on if os.path.isfile(thepath):/else statement blocks are probably more suitable.

How about grep:

pwd | grep -o '[^/]*$'

You can use JavaScript, no jQuery required:

var someDate = new Date();
var numberOfDaysToAdd = 6;
someDate.setDate(someDate.getDate() + numberOfDaysToAdd); 
Formatting to dd/mm/yyyy :

var dd = someDate.getDate();
var mm = someDate.getMonth() + 1;
var y = someDate.getFullYear();

var someFormattedDate = dd + '/'+ mm + '/'+ y;

 SELECT name, email 
    FROM users
    WHERE email in
    (SELECT email FROM users
    GROUP BY email 
    HAVING COUNT(*)>1)

For anyone looking for a solution to this with also wanting to cycle the elements, below might work -

from collections import deque  

foo = ['A', 'B', 'C', 'D']

def prev_and_next(input_list):
    CURRENT = input_list
    PREV = deque(input_list)
    PREV.rotate(-1)
    PREV = list(PREV)
    NEXT = deque(input_list)
    NEXT.rotate(1)
    NEXT = list(NEXT)
    return zip(PREV, CURRENT, NEXT)

for previous_, current_, next_ in prev_and_next(foo):
    print(previous_, current_, next)

Yes, it is a non-type parameter. You can have several kinds of template parameters

• Type Parameters.
  • Types
  • Templates (only classes and alias templates, no functions or variable templates)
• Non-type Parameters
  • Pointers
  • References
  • Integral constant expressions

What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:

Template type parameter:

template<typename T>
struct Container {
    T t;
};

// pass type "long" as argument.
Container<long> test;

Template integer parameter:

template<unsigned int S>
struct Vector {
    unsigned char bytes[S];
};

// pass 3 as argument.
Vector<3> test;

Template pointer parameter (passing a pointer to a function)

template<void (*F)()>
struct FunctionWrapper {
    static void call_it() { F(); }
};

// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;

Template reference parameter (passing an integer)

template<int &A>
struct SillyExample {
    static void do_it() { A = 10; }
};

// pass flag as argument
int flag;
SillyExample<flag> test;

Template template parameter.

template<template<typename T> class AllocatePolicy>
struct Pool {
    void allocate(size_t n) {
        int *p = AllocatePolicy<int>::allocate(n);
    }
};

// pass the template "allocator" as argument. 
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;

A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:

template<unsigned int SIZE = 3>
struct Vector {
    unsigned char buffer[SIZE];
};

Vector<> test;

Syntactically, template<> is reserved to mark an explicit template specialization, instead of a template without parameters:

template<>
struct Vector<3> {
    // alternative definition for SIZE == 3
};

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

    View view = inflater.inflate(R.layout.writeqrcode_main, container, false);
    // Inflate the layout for this fragment

    txt_name = (TextView) view.findViewById(R.id.name);
    txt_usranme = (TextView) view.findViewById(R.id.surname);
    txt_number = (TextView) view.findViewById(R.id.number);
    txt_province = (TextView) view.findViewById(R.id.province);
    txt_write = (EditText) view.findViewById(R.id.editText_write);
    txt_show1 = (Button) view.findViewById(R.id.buttonShow1);

    txt_show1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e("Onclick","Onclick");

            txt_show1.setVisibility(View.INVISIBLE);
            txt_name.setVisibility(View.VISIBLE);
            txt_usranme.setVisibility(View.VISIBLE);
            txt_number.setVisibility(View.VISIBLE);
            txt_province.setVisibility(View.VISIBLE);
        }
    });
    return view;
}

You OK !!!!

There are other solutions you can look into http://ngmodules.org/modules/ngUpload as discussed here file uploader integration for angularjs

@AlaxDean's #7 answer, Argonaut is the only one that I was able to get working quickly with sbt and intellij. Actually json4s also took little time but dealing with a raw AST is not what I wanted. I got argonaut to work by putting in a single line into my build.st:

libraryDependencies += "io.argonaut" %% "argonaut" % "6.0.1"

And then a simple test to see if it I could get JSON:

package mytest


import scalaz._, Scalaz._
import argonaut._, Argonaut._

object Mytest extends App {

  val requestJson  =
    """
    {
      "userid": "1"
    }
    """.stripMargin

  val updatedJson: Option[Json] = for {
    parsed <- requestJson.parseOption
  } yield ("name", jString("testuser")) ->: parsed

  val obj = updatedJson.get.obj
  printf("Updated user: %s\n", updatedJson.toString())
  printf("obj : %s\n", obj.toString())
  printf("userid: %s\n", obj.get.toMap("userid"))
}

And then

$ sbt
> run
Updated user: Some({"userid":"1","name":"testuser"})
obj : Some(object[("userid","1"),("name","testuser")])
userid: "1"

Make sure you are familiar with Option which is just a value that can also be null (null safe I guess). Argonaut makes use of Scalaz so if you see something you don't understand like the symbol \/ (an or operation) it's probably Scalaz.

You can just convert everything to lowercase for the purposes of sorting:

SELECT * FROM NOTES ORDER BY LOWER(title);

If you want to make sure that the uppercase ones still end up ahead of the lowercase ones, just add that as a secondary sort:

SELECT * FROM NOTES ORDER BY LOWER(title), title;

Another problem is that CSS has to be defined outside component scope, breaking component encapsulation

This is not true. With scss (SASS) you can easily style the component (itself;host) as so:

:host {
    display: block;
    position: absolute;
    width: 100%;
    height: 100%;
    pointer-events: none;
    visibility: hidden;

    &.someClass {
        visibility: visible;
    }
}

This way the encapsulation is "unbroken".

the difference is not between <span> and <div> specifically, but between inline and block elements. <span> defaults to being display:inline; whereas <div> defaults to being display:block;. But these can be overridden in CSS.

The difference in the way text-align:center works between the two is down to the width.

A block element defaults to being the width of its container. It can have its width set using CSS, but either way it is a fixed width.

An inline element takes its width from the size of its content text.

text-align:center tells the text to position itself centrally in the element. But in an inline element, this is clearly not going to have any effect because the element is the same width as the text; aligning it one way or the other is meaningless.

In a block element, because the element's width is independent of the content, the content can be positioned within the element using the text-align style.

Finally, a solution for you:

There is an additional value for the display property which provides a half-way house between block and inline. Conveniently enough, it's called inline-block. If you specify a <span> to be display:inline-block; in the CSS, it will continue to work as an inline element but will take on some of the properties of a block as well, such as the ability to specify a width. Once you specify a width for it, you will be able to center the text within that width using text-align:center;

Hope that helps.

When using the for loop, the value of s is a Map.Entry element, meaning that you can get the key from s.key and the value from s.value

Firstly, check the IP address that your application has bound to. It could only be binding to a local address, for example, which would mean that you'd never see it from a different machine regardless of firewall states.

You could try using a portscanner like nmap to see if the port is open and visible externally... it can tell you if the port is closed (there's nothing listening there), open (you should be able to see it fine) or filtered (by a firewall, for example).

Adding to @Greg Hewgill answer: if you want to be able to match both date-time and only date, you can make the "time" part of the regex optional:

(\d{4})-(\d{2})-(\d{2})( (\d{2}):(\d{2}):(\d{2}))?

this way you will match both 2008-09-01 12:35:42 and 2008-09-01

#!/usr/bin/python

Try This to starting of python file

Two ways to do this:

1) Using a Frame Layout

android:layout_gravity="bottom|right"

2) Using a Relative Layout

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

You need to return to normal mode and save the commit message with either

<Esc>:wq

or

<Esc>:x

or

<Esc>ZZ

The Esc key returns you from insert mode to normal mode. The :wq, :x or ZZ sequence writes the changes and exits the editor.

If you control both the HTML and CSS, I'd suggest switching to using ID's on all the divs needed for the rounded corner.

CSS

#d1 {
    background: #CFFEB6 url('tr.gif') no-repeat top right;
}
#d2 {
    background: url('br.gif') no-repeat bottom right;
}
#d3 {
    background: url('bl.gif') no-repeat bottom left;
}
#d4 {
    padding: 10px;
}

HTML

<div id="d1"><div id="d2"><div id="d3"><div id="d4">
    <div class='button'><a href='#'>Test</a></div>
</div></div></div></div>

If you are only interested in the bit (resp hex pattern) you could use the %a format. This guarantees you:

The default precision suffices for an exact representation of the value if an exact representation in base 2 exists and otherwise is sufficiently large to distinguish values of type double.

I'd have to add that this is only available since C99.

For use key/value pair in json use an object and don't use array

Find name/value in array is hard but in object is easy

Ex:

var exObj = {_x000D_
  "mainData": {_x000D_
    "slide0001.html": "Looking Ahead",_x000D_
    "slide0008.html": "Forecast",_x000D_
    "slide0021.html": "Summary",_x000D_
    // another THOUSANDS KEY VALUE PAIRS_x000D_
    // ..._x000D_
  },_x000D_
  "otherdata" : { "one": "1", "two": "2", "three": "3" }_x000D_
};_x000D_
var mainData = exObj.mainData;_x000D_
// for use:_x000D_
Object.keys(mainData).forEach(function(n,i){_x000D_
  var v = mainData[n];_x000D_
  console.log('name' + i + ': ' + n + ', value' + i + ': ' + v);_x000D_
});_x000D_
_x000D_
// and string length is minimum_x000D_
console.log(JSON.stringify(exObj));_x000D_
console.log(JSON.stringify(exObj).length);

JavaScript works in milliseconds, so you'll first have to convert the UNIX timestamp from seconds to milliseconds.

var date = new Date(UNIX_Timestamp * 1000);
// Manipulate JavaScript Date object here...

1. Go to the log view (to be able to go here go to View -> log view).
2. Double click on the line with the branch label stating that branch. Automatically, it will switch branch. (A prompt will dropdown and say switching branch.)
3. If you have two or more branches on the same line, it will ask you via prompt which branch you want to switch. Choose the specific branch from the dropdown and click ok.

To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.

If you had use strict turned on, you would have found out that $++foo doesn't make any sense.

Here's how to do it:

use strict;
use warnings;

my $file = 'SnPmaster.txt';
open my $info, $file or die "Could not open $file: $!";

while( my $line = <$info>)  {   
    print $line;    
    last if $. == 2;
}

close $info;

This takes advantage of the special variable $. which keeps track of the line number in the current file. (See perlvar)

If you want to use a counter instead, use

my $count = 0;
while( my $line = <$info>)  {   
    print $line;    
    last if ++$count == 2;
}

Looks like the solution as.numeric(levels(f))[f] no longer work with R 4.0.

Alternative solution:

factor2number <- function(x){
    data.frame(levels(x), 1:length(levels(x)), row.names = 1)[x, 1]
}

factor2number(yourFactor)

I have found that wget does not properly authenticate with some servers, perhaps because it is only HTTP 1.0 compliant. In such cases, curl (which is HTTP 1.1 compliant) usually does the trick:

curl -o <filename-to-save-as> -u <username>:<password> <url>

Here is the C++ implementation of Jon Skeets Answer. It might not be the most optimal way of implementing it, but it does exactly what it's supposed to.

class Stack {
private:
    struct stack_node {
        int val;
        stack_node *next;
    };
    stack_node *top;
    stack_node *min_top;
public:
    Stack() {
        top = nullptr;
        min_top = nullptr;
    }    
    void push(int num) {
        stack_node *new_node = nullptr;
        new_node = new stack_node;
        new_node->val = num;

        if (is_empty()) {
            top = new_node;
            new_node->next = nullptr;

            min_top = new_node;
            new_node->next = nullptr;
        } else {
            new_node->next = top;
            top = new_node;

            if (new_node->val <= min_top->val) {
                new_node->next = min_top;
                min_top = new_node;
            }
        }
    }

    void pop(int &num) {
        stack_node *tmp_node = nullptr;
        stack_node *min_tmp = nullptr;

        if (is_empty()) {
            std::cout << "It's empty\n";
        } else {
            num = top->val;
            if (top->val == min_top->val) {
                min_tmp = min_top->next;
                delete min_top;
                min_top = min_tmp;
            }
            tmp_node = top->next;
            delete top;
            top = tmp_node;
        }
    }

    bool is_empty() const {
        return !top;
    }

    void get_min(int &item) {
        item = min_top->val;
    }
};

And here is the driver for the class

int main() {
    int pop, min_el;
    Stack my_stack;

    my_stack.push(4);
    my_stack.push(6);
    my_stack.push(88);
    my_stack.push(1);
    my_stack.push(234);
    my_stack.push(2);

    my_stack.get_min(min_el);
    cout << "Min: " << min_el << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.get_min(min_el);
    cout << "Min: " << min_el << endl;

    return 0;
}

Output:

Min: 1
Popped stock element: 2
Popped stock element: 234
Popped stock element: 1
Min: 4

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

There is no 'method in a math class' for such thing. Its not like its a square root function or something like that.

You just need to have a variable for the sum and loop through the array adding each value you find to the sum.

Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:

JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);

According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:

 Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
 return font.deriveFont(12f);

Query_string

(Following is the text of the linked section of the Wikipedia entry.)

Structure

A typical URL containing a query string is as follows:

http://server/path/program?query_string

When a server receives a request for such a page, it runs a program (if configured to do so), passing the query_string unchanged to the program. The question mark is used as a separator and is not part of the query string.

A link in a web page may have a URL that contains a query string, however, HTML defines three ways a web browser can generate the query string:

• a web form via the ... element
• a server-side image map via the ?ismap? attribute on the element with a construction
• an indexed search via the now deprecated element

Web forms

The main use of query strings is to contain the content of an HTML form, also known as web form. In particular, when a form containing the fields field1, field2, field3 is submitted, the content of the fields is encoded as a query string as follows:

field1=value1&field2=value2&field3=value3...

• The query string is composed of a series of field-value pairs.
• Within each pair, the field name and value are separated by an equals sign. The equals sign may be omitted if the value is an empty string.
• The series of pairs is separated by the ampersand, '&' (or semicolon, ';' for URLs embedded in HTML and not generated by a ...; see below). While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field:

field1=value1&field1=value2&field1=value3...

For each field of the form, the query string contains a pair field=value. Web forms may include fields that are not visible to the user; these fields are included in the query string when the form is submitted

This convention is a W3C recommendation. W3C recommends that all web servers support semicolon separators in addition to ampersand separators[6] to allow application/x-www-form-urlencoded query strings in URLs within HTML documents without having to entity escape ampersands.

Technically, the form content is only encoded as a query string when the form submission method is GET. The same encoding is used by default when the submission method is POST, but the result is not sent as a query string, that is, is not added to the action URL of the form. Rather, the string is sent as the body of the HTTP request.

Thank you to SLaks and jpm for their help. It was a pretty simple error that I simply did not see.

As SLaks pointed out, br.readLine() was being called twice each loop which made the program only get half of the values. Here is the fixed code:

try{
        InputStream fis=new FileInputStream(targetsFile);
        BufferedReader br=new BufferedReader(new InputStreamReader(fis));
        String words[]=new String[5];
        String line=null;
        while((line=br.readLine())!=null){
            words=line.split(" ");
            int targetX=Integer.parseInt(words[0]);
            int targetY=Integer.parseInt(words[1]);
            int targetW=Integer.parseInt(words[2]);
            int targetH=Integer.parseInt(words[3]);
            int targetHits=Integer.parseInt(words[4]);
            Target a=new Target(targetX, targetY, targetW, targetH, targetHits);
            targets.add(a);
        }
        br.close();
    }
    catch(Exception e){
        System.err.println("Error: Target File Cannot Be Read");
    }

Thanks again! You guys are great!

You need to create a file named org.apache.cxf.Logger (that is: org.apache.cxf file with Logger extension) under /META-INF/cxf/ with the following contents:

org.apache.cxf.common.logging.Log4jLogger

Reference: Using Log4j Instead of java.util.logging.

Also if you replace standard:

<cxf:bus>
  <cxf:features>
    <cxf:logging/>
  </cxf:features>
</cxf:bus>

with much more verbose:

<bean id="abstractLoggingInterceptor" abstract="true">
    <property name="prettyLogging" value="true"/>
</bean>
<bean id="loggingInInterceptor" class="org.apache.cxf.interceptor.LoggingInInterceptor" parent="abstractLoggingInterceptor"/>

Apache CXF will pretty print XML messages formatting them with proper indentation and line breaks. Very useful. More about it here.

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

You are absolutely right, supporting completely stateless interactions with the server does put an additional burden on the client. However, if you consider scaling an application, the computation power of the clients is directly proportional to the number of clients. Therefore scaling to high numbers of clients is much more feasible.

As soon as you put a tiny bit of responsibility on the server to manage some information related to a specific client's interactions, that burden can quickly grow to consume the server.

It's a trade off.

don't give this in file input value="123".

  $(document).ready(function(){  

      var img = $('#uploadPicture').val();

  });

Some applications may detect click source at low OS level. If you really need that kind of hack, you may just run target app in virtual machine's window, and run cliker in host OS, it can help.

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

//paste required image on C disk
JButton button = new JButton(new ImageIcon("C:water.bmp");

See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for "BEGIN RSA PRIVATE KEY") (archive link for posterity, just in case).

BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that the key type is included in the key data itself. From the link:

The unencrypted PKCS#8 encoded data starts and ends with the tags:

-----BEGIN PRIVATE KEY-----
BASE64 ENCODED DATA
-----END PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

PrivateKeyInfo ::= SEQUENCE {
  version         Version,
  algorithm       AlgorithmIdentifier,
  PrivateKey      BIT STRING
}

AlgorithmIdentifier ::= SEQUENCE {
  algorithm       OBJECT IDENTIFIER,
  parameters      ANY DEFINED BY algorithm OPTIONAL
}

So for an RSA private key, the OID is 1.2.840.113549.1.1.1 and there is a RSAPrivateKey as the PrivateKey key data bitstring.

As opposed to BEGIN RSA PRIVATE KEY, which always specifies an RSA key and therefore doesn't include a key type OID. BEGIN RSA PRIVATE KEY is PKCS#1:

RSA Private Key file (PKCS#1)

The RSA private key PEM file is specific for RSA keys.

It starts and ends with the tags:

-----BEGIN RSA PRIVATE KEY-----
BASE64 ENCODED DATA
-----END RSA PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

RSAPrivateKey ::= SEQUENCE {
  version           Version,
  modulus           INTEGER,  -- n
  publicExponent    INTEGER,  -- e
  privateExponent   INTEGER,  -- d
  prime1            INTEGER,  -- p
  prime2            INTEGER,  -- q
  exponent1         INTEGER,  -- d mod (p-1)
  exponent2         INTEGER,  -- d mod (q-1)
  coefficient       INTEGER,  -- (inverse of q) mod p
  otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

The answer depends on what is in your hash. If you have a simple hash a simple

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

pyarrow compatibility across versions

Overall move has been to pyarrow/feather (deprecation warnings from pandas/msgpack). However I have a challenge with pyarrow with transient in specification Data serialized with pyarrow 0.15.1 cannot be deserialized with 0.16.0 ARROW-7961. I'm using serialization to use redis so have to use a binary encoding.

I've retested various options (using jupyter notebook)

import sys, pickle, zlib, warnings, io
class foocls:
    def pyarrow(out): return pa.serialize(out).to_buffer().to_pybytes()
    def msgpack(out): return out.to_msgpack()
    def pickle(out): return pickle.dumps(out)
    def feather(out): return out.to_feather(io.BytesIO())
    def parquet(out): return out.to_parquet(io.BytesIO())

warnings.filterwarnings("ignore")
for c in foocls.__dict__.values():
    sbreak = True
    try:
        c(out)
        print(c.__name__, "before serialization", sys.getsizeof(out))
        print(c.__name__, sys.getsizeof(c(out)))
        %timeit -n 50 c(out)
        print(c.__name__, "zlib", sys.getsizeof(zlib.compress(c(out))))
        %timeit -n 50 zlib.compress(c(out))
    except TypeError as e:
        if "not callable" in str(e): sbreak = False
        else: raise
    except (ValueError) as e: print(c.__name__, "ERROR", e)
    finally: 
        if sbreak: print("=+=" * 30)        
warnings.filterwarnings("default")

feather and parquet do not work for my data frame. I'm going to continue using pyarrow. However I will supplement with pickle (no compression). When writing to cache store pyarrow and pickle serialised forms. When reading from cache fallback to pickle if pyarrow deserialisation fails.

Use case wise the following seem to be easy to use and fast. Just set the page number.

yum update

helped me out. After I had

wget: symbol lookup error: wget: undefined symbol: psl_latest

Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.

public ActionResult ClientIdSearch(int cid)
{
  var action = String.Format("Details/{0}", cid);

  return RedirectToAction(action, "Accounts");
}

I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.

I started working on this problem a long time ago, trying to write my own binary to decimal converter function. I don't actually know how to convert decimal to binary though! I just revisited it today and figured it out and this is what I came up with. I'm not sure if this is what you need, but here it is:

def __degree(number):
    power = 1

    while number % (10**power) != number:
        power += 1

    return power

def __getDigits(number):
    digits = []
    degree = __degree(number)

    for x in range(0, degree):
        digits.append(int(((number % (10**(degree-x))) - (number % (10**(degree-x-1)))) / (10**(degree-x-1))))
    return digits

def binaryToDecimal(number):
    list = __getDigits(number)
    decimalValue = 0
    for x in range(0, len(list)):
        if (list[x] is 1):
            decimalValue += 2**(len(list) - x - 1)
    return decimalValue

Again, I'm still learning Python just on my own, hopefully this helps. The first function determines how many digits there are, the second function actually figures out they are and returns them in a list, and the third function is the only one you actually need to call, and it calculates the decimal value. If your teacher actually wanted you to write your own converter, this works, I haven't tested it with every number, but it seems to work perfectly! I'm sure you'll all find the bugs for me! So anyway, I just called it like:

binaryNum = int(input("Enter a binary number: "))

print(binaryToDecimal(binaryNum))

This prints out the correct result. Cheers!

I use both Charles Proxy and Fiddler for my HTTP/HTTPS level debugging.

Pros of Charles Proxy:

1. Handles HTTPS better (you get a Charles Certificate which you'd put in 'Trusted Authorities' list)
2. Has more features like Load/Save Session (esp. useful when debugging multiple pages), Mirror a website (useful in caching assets and hence faster debugging), etc.
3. As mentioned by jburgess, handles AMF.
4. Displays JSON, XML and other kind of responses in a tree structure, making it easier to read. Displays images in image responses instead of binary data.

Cons of Charles Proxy:

1. Cost :-)

At the risk of being years late and off topic - and notwithstanding @Marc's excellent insight, in Swift it looks like:

let basename = NSURL(string: "path/to/file.ext")?.URLByDeletingPathExtension?.lastPathComponent

System is a class in java.lang package.

out is the static data member in System class and reference variable of PrintStream class.

Println() is a normal (overloaded) method of PrintStream class.

print "%02d"%a is the python 2 variant

python 3 uses a somewhat more verbose formatting system:

"{0:0=2d}".format(a)

The relevant doc link for python2 is: http://docs.python.org/2/library/string.html#format-specification-mini-language

For python3, it's http://docs.python.org/3/library/string.html#string-formatting

This is a refined and better performing variant:

String.prototype.hashCode = function() {
    var hash = 0, i = 0, len = this.length;
    while ( i < len ) {
        hash  = ((hash << 5) - hash + this.charCodeAt(i++)) << 0;
    }
    return hash;
};

This matches Java's implementation of the standard object.hashCode()

Here is also one that returns only positive hashcodes:

String.prototype.hashcode = function() {
    return (this.hashCode() + 2147483647) + 1;
};

And here is a matching one for Java that only returns positive hashcodes:

public static long hashcode(Object obj) {
    return ((long) obj.hashCode()) + Integer.MAX_VALUE + 1l;
}

Enjoy!

Without prototype:

function hashCode(str) {
    var hash = 0, i = 0, len = str.length;
    while ( i < len ) {
        hash  = ((hash << 5) - hash + str.charCodeAt(i++)) << 0;
    }
    return hash;
}

To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:

with g as outfile:
  json.dump(hostDict, outfile,indent=2)

Using indent = 2 helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.

Try replacing this

var query = context.Search(id, searchText);

with

var query = context.Search(id, searchText).tolist();

and everything will work well.

The other solution are OK, but there is no need to add separator at the very last if using :after or at the very beginning if using :before.

SO:

case :after

.link:after {
  content: '|';
  padding: 0 1rem;
}

.link:last-child:after {
  content: '';
}

case :before

.link:before {
  content: '|';
  padding: 0 1rem;
}

.link:first-child:before {
  content: '';
}

As others have indicated, something of the form

x ? y : z

is an expression, not a (complete) statement. It is an rvalue which needs to get used someplace - like on the right side of an assignment, or a parameter to a function etc.

Perhaps you could look at this: http://download.oracle.com/javase/tutorial/java/nutsandbolts/expressions.html

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

<input type='file' onchange='getFilename(this)'/>

function getFileName(elm) {
   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {
   var fn = $(elm).val();
   var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
   alert(filename);
}

A colleague told me about this stored procedure...

USE msdb

EXEC dbo.sp_help_job

Here you can simply use:

SendKeys "{ENTER}" at the end of code linked to the Username field.

And so you can skip pressing ENTER Key once (one time).
And as a result, the next button ("Log In" button here) will be activated. And when you press ENTER once (your desired outcome), It will run code which is linked with "Log In" button.

I felt that we were lacking certain kinds of sub string counting, like unsafe byte-by-byte comparisons. I put together the original poster's method and any methods I could think of.

These are the string extensions I made.

}

Results: CSX corresponds with CountSubstrX and CCX corresponds with CountCharX. "chr" searches a string for '_', "and" searches a string for "and", and "mlw" searches a string for "muchlongerword"

CS1 chr: 824.123ms
CS1 and: 586.1893ms
CS1 mlw: 486.5414ms
CS2 chr: 127.8941ms
CS2 and: 806.3918ms
CS2 mlw: 497.318ms
CS3 chr: 201.8896ms
CS3 and: 124.0675ms
CS3 mlw: 212.8341ms
CS4 chr: 81.5183ms
CS4 and: 92.0615ms
CS4 mlw: 116.2197ms
CC1 chr: 66.4078ms
CC2 chr: 64.0161ms
CC3 chr: 65.9013ms
CC4 chr: 65.8206ms

And finally, I had a file with 3.6 million characters. It was "derp adfderdserp dfaerpderp deasderp" repeated 100,000 times. I searched for "derp" inside the file with the above methods 100 times these results.

CS1Derp: 1501.3444ms
CS2Derp: 1585.797ms
CS3Derp: 376.0937ms
CS4Derp: 271.1663ms

So my 4th method is definitely the winner, but, realistically, if a 3.6 million character file 100 times only took 1586ms as the worse case, then all of this is quite negligible.

By the way, I also scanned for the 'd' char in the 3.6 million character file with 100 times CountSubstr and CountChar methods. Results...

CS1  d : 2606.9513ms
CS2  d : 339.7942ms
CS3  d : 960.281ms
CS4  d : 233.3442ms
CC1  d : 302.4122ms
CC2  d : 280.7719ms
CC3  d : 299.1125ms
CC4  d : 292.9365ms

The original posters method is very bad for single character needles in a large haystack according to this.

Note: All values were updated to Release version output. I accidentally forgot to build on Release mode upon the first time I posted this. Some of my statements have been amended.

You are not indicating what to include in the archive.

Go one level outside your folder and try:

sudo tar -cvjSf folder.tar.bz2 folder

Or from the same folder try

sudo tar -cvjSf folder.tar.bz2 *

I could do that following the steps:

1. Create a folder __mocks__/ (as pointed by @Januartha comment)
2. Implement an axios.js mock file
3. Use my implemented module on test

The mock will happen automatically

Example of the mock module:

module.exports = {
    get: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
    }),
    post: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
        if (url === '/something2') {
            return Promise.resolve({
                data: 'data2'
            });
        }
    }),
    create: jest.fn(function () {
        return this;
    })
};

For check of email use email_validator

from email_validator import validate_email, EmailNotValidError

def check_email(email):
    try:
        v = validate_email(email)  # validate and get info
        email = v["email"]  # replace with normalized form
        print("True")
    except EmailNotValidError as e:
        # email is not valid, exception message is human-readable
        print(str(e))

check_email("test@gmailcom")

2>&1 is a POSIX shell construct. Here is a breakdown, token by token:

2: "Standard error" output file descriptor.

>&: Duplicate an Output File Descriptor operator (a variant of Output Redirection operator >). Given [x]>&[y], the file descriptor denoted by x is made to be a copy of the output file descriptor y.

1 "Standard output" output file descriptor.

The expression 2>&1 copies file descriptor 1 to location 2, so any output written to 2 ("standard error") in the execution environment goes to the same file originally described by 1 ("standard output").

Further explanation:

File Descriptor: "A per-process unique, non-negative integer used to identify an open file for the purpose of file access."

Standard output/error: Refer to the following note in the Redirection section of the shell documentation:

Open files are represented by decimal numbers starting with zero. The largest possible value is implementation-defined; however, all implementations shall support at least 0 to 9, inclusive, for use by the application. These numbers are called "file descriptors". The values 0, 1, and 2 have special meaning and conventional uses and are implied by certain redirection operations; they are referred to as standard input, standard output, and standard error, respectively. Programs usually take their input from standard input, and write output on standard output. Error messages are usually written on standard error. The redirection operators can be preceded by one or more digits (with no intervening characters allowed) to designate the file descriptor number.

Bash:

 find -type f -printf "%T@ %p \n" \
     | sort  \
     | tail -n 1  \
     | sed -r "s/^\S+\s//;s/\s*$//" \
     | xargs -iSTR cp STR newestfile

where "newestfile" will become the newestfile

alternatively, you could do newdir/STR or just newdir

Breakdown:

1. list all files in {time} {file} format.
2. sort them by time
3. get the last one
4. cut off the time, and whitespace from the start/end
5. copy resulting value

Important

After running this once, the newest file will be whatever you just copied :p ( assuming they're both in the same search scope that is ). So you may have to adjust which filenumber you copy if you want this to work more than once.

You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C

The following article explains more about using Mac OS's Color Picker.

It means you should use logging framework like logback or log4j and instead of printing exceptions directly:

e.printStackTrace();

you should log them using this frameworks' API:

log.error("Ops!", e);

Logging frameworks give you a lot of flexibility, e.g. you can choose whether you want to log to console or file - or maybe skip some messages if you find them no longer relevant in some environment.

Try this:

List< Object> myList = x.getName;
myList.sort(Comparator.comparing(Object::getName));

I am a little late but I used this:

dir /B *.* > dir_file.txt

then you can make a simple FOR loop to extract the file name and use them. e.g:

for /f "tokens=* delims= " %%a in (dir_file.txt) do (
gawk -f awk_script_file.awk %%a
)

or store them into Vars (!N1!, !N2!..!Nn!) for later use. e.g:

set /a N=0
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
set /a N+=1
set v[!N!]=%%a
)

I had the same issue recently and ended up creating a NuGet package for this.

This implements a standard heap-based priority queue. It also has all the usual niceties of the BCL collections: ICollection<T> and IReadOnlyCollection<T> implementation, custom IComparer<T> support, ability to specify an initial capacity, and a DebuggerTypeProxy to make the collection easier to work with in the debugger.

There is also an Inline version of the package which just installs a single .cs file into your project (useful if you want to avoid taking externally-visible dependencies).

More information is available on the github page.

I've been looking through stack overflow to find a good answer and when i couldn't find one i went looking through the docs.

no one seems to have stumbled on this simple answer yet:

ViewCompat.setTranslationZ(view, translationZ);

default translation z is 0.0

You can also use numpy.subtract

It has the advantage over the difference operator, -, that you do not have to transform the sequences (list or tuples) into a numpy arrays — you save the two commands:

array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])

Example: (Python 3.5)

import numpy as np
result = np.subtract([1.1, 2.2, 3.3], [1, 2, 3])
print ('the difference =', result)

which gives you

the difference = [ 0.1  0.2  0.3]

Remember, however, that if you try to subtract sequences (lists or tuples) with the - operator you will get an error. In this case, you need the above commands to transform the sequences in numpy arrays

Wrong Code:

print([1.1, 2.2, 3.3] - [1, 2, 3])

If your environment doesn't allow overwriting with >, use pipe | and tee instead as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt'

Note this will also print to the stdout. In case this is unwanted, you can redirect the output to /dev/null as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt' > /dev/null

You can simply get the reference of your buttons using jQuery, and prevent its propagation like below:

 $(document).ready(function () {
    $('#BUTTON_ID').click(function(e) {

            e.preventDefault();
            e.stopPropagation();
            e.stopImmediatePropagation();

            return false;
    });});

For 12 hour clock with suffix "AM" or "PM" :-

DateFormat df = new SimpleDateFormat("KK:mm:ss a, dd/MM/yyyy",Locale.getDefault());
        String currentDateAndTime = df.format(new Date());

For 24 hour clock with suffix "AM" or "PM":-

 DateFormat df = new SimpleDateFormat("HH:mm:ss a, dd/MM/yyyy",Locale.getDefault());
            String currentDateAndTime = df.format(new Date());

to remove the suffix just remove "a" written with time format

I agree with Honest Abe that the match(...) in the given examples are different. They are not a one-to-one comparisons and thus, outcomes are vary. To simplify my reply, I use A, B, C, D for those functions in question. Oh yes, we are dealing with 4 functions in re.py instead of 3.

Running this piece of code:

h = re.compile('hello')                   # (A)
h.match('hello world')                    # (B)

is same as running this code:

re.match('hello', 'hello world')          # (C)

Because, when looked into the source re.py, (A + B) means:

h = re._compile('hello')                  # (D)
h.match('hello world')

and (C) is actually:

re._compile('hello').match('hello world')

So, (C) is not the same as (B). In fact, (C) calls (B) after calling (D) which is also called by (A). In other words, (C) = (A) + (B). Therefore, comparing (A + B) inside a loop has same result as (C) inside a loop.

George's regexTest.py proved this for us.

noncompiled took 4.555 seconds.           # (C) in a loop
compiledInLoop took 4.620 seconds.        # (A + B) in a loop
compiled took 2.323 seconds.              # (A) once + (B) in a loop

Everyone's interest is, how to get the result of 2.323 seconds. In order to make sure compile(...) only get called once, we need to store the compiled regex object in memory. If we are using a class, we could store the object and reuse when every time our function get called.

class Foo:
    regex = re.compile('hello')
    def my_function(text)
        return regex.match(text)

If we are not using class (which is my request today), then I have no comment. I'm still learning to use global variable in Python, and I know global variable is a bad thing.

One more point, I believe that using (A) + (B) approach has an upper hand. Here are some facts as I observed (please correct me if I'm wrong):

1. Calls A once, it will do one search in the _cache followed by one sre_compile.compile() to create a regex object. Calls A twice, it will do two searches and one compile (because the regex object is cached).

2. If the _cache get flushed in between, then the regex object is released from memory and Python need to compile again. (someone suggest that Python won't recompile.)

3. If we keep the regex object by using (A), the regex object will still get into _cache and get flushed somehow. But our code keep a reference on it and the regex object will not be released from memory. Those, Python need not to compile again.

4. The 2 seconds differences in George's test compiledInLoop vs compiled is mainly the time required to build the key and search the _cache. It doesn't mean the compile time of regex.

5. George's reallycompile test show what happen if it really re-do the compile every time: it will be 100x slower (he reduced the loop from 1,000,000 to 10,000).

Here are the only cases that (A + B) is better than (C):

1. If we can cache a reference of the regex object inside a class.
2. If we need to calls (B) repeatedly (inside a loop or multiple times), we must cache the reference to regex object outside the loop.

Case that (C) is good enough:

1. We cannot cache a reference.
2. We only use it once in a while.
3. In overall, we don't have too many regex (assume the compiled one never get flushed)

Just a recap, here are the A B C:

h = re.compile('hello')                   # (A)
h.match('hello world')                    # (B)
re.match('hello', 'hello world')          # (C)

Thanks for reading.

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

Your '/0' should be '\0' .. you got the slash reversed/leaning the wrong way. Your while should look like:

while (*(forward++)!='\0') 

though the != '\0' part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).

All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t', or newline '\n', and the same for null '\0' so it's easy to remember.

since HashMap implements Serializable interface, you can simply use ObjectOutputStream class to write whole Map to file, and read it again using ObjectInputStream class

below simple code that explain usage of ObjectOutStream and ObjectInputStream

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A() {
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method1(hm);

    }

public void method1(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileOne=new File("fileone");
        FileOutputStream fos=new FileOutputStream(fileOne);
        ObjectOutputStream oos=new ObjectOutputStream(fos);

        oos.writeObject(map);
        oos.flush();
        oos.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("fileone");
        FileInputStream fis=new FileInputStream(toRead);
        ObjectInputStream ois=new ObjectInputStream(fis);

        HashMap<String,String> mapInFile=(HashMap<String,String>)ois.readObject();

        ois.close();
        fis.close();
        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()){
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    } catch(Exception e) {}
  }

public static void main(String args[]) {
        new A();
}

}

or if you want to write data as text to file you can simply iterate through Map and write key and value line by line, and read it again line by line and add to HashMap

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A(){
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method2(hm);

    }

public void method2(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileTwo=new File("filetwo.txt");
        FileOutputStream fos=new FileOutputStream(fileTwo);
        PrintWriter pw=new PrintWriter(fos);

        for(Map.Entry<String,String> m :map.entrySet()){
            pw.println(m.getKey()+"="+m.getValue());
        }

        pw.flush();
        pw.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("filetwo.txt");
        FileInputStream fis=new FileInputStream(toRead);

        Scanner sc=new Scanner(fis);

        HashMap<String,String> mapInFile=new HashMap<String,String>();

        //read data from file line by line:
        String currentLine;
        while(sc.hasNextLine()) {
            currentLine=sc.nextLine();
            //now tokenize the currentLine:
            StringTokenizer st=new StringTokenizer(currentLine,"=",false);
            //put tokens ot currentLine in map
            mapInFile.put(st.nextToken(),st.nextToken());
        }
        fis.close();

        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()) {
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    }catch(Exception e) {}
  }

public static void main(String args[]) {
        new A();
}

}

NOTE: above code may not be the fastest way to doing this task, but i want to show some application of classes

See ObjectOutputStream , ObjectInputStream, HashMap, Serializable, StringTokenizer

How about this?

SET ROWCOUNT 10 

SELECT TOP 20 *
FROM sys.databases
ORDER BY database_id DESC

It gives you the last 10 rows of the first 20 rows. One drawback is that the order is reversed, but, at least it's easy to remember.

Plain Java 8 solutions using a Stream.

Constant number

Assuming private Collection<T> c, c2, c3.

One solution:

public Stream<T> stream() {
    return Stream.concat(Stream.concat(c.stream(), c2.stream()), c3.stream());
}

Another solution:

public Stream<T> stream() {
    return Stream.of(c, c2, c3).flatMap(Collection::stream);
}

Variable number

Assuming private Collection<Collection<T>> cs:

public Stream<T> stream() {
    return cs.stream().flatMap(Collection::stream);
}

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

Or you may try this:

According to the documentation:

BigInteger(String val)

Translates the decimal String representation of a BigInteger into a BigInteger.

It means that you can use a String to initialize a BigInteger object, as shown in the following snippet:

sum = sum.add(new BigInteger(newNumber));

I have a similar scenario, and had no problem connecting after setting the JNLP port as you describe, and adding a single firewall rule allowing a connection on the server using that port. Granted it is a randomly selected client port going to a known server port (a host:ANY -> server:1 rule is needed).

From my reading of the source code, I don't see a way to set the local port to use when making the request from the slave. It's unfortunate, it would be a nice feature to have.

Alternatives:

Use a simple proxy on your client that listens on port N and then does forward all data to the actual Jenkins server on the remote host using a constant local port. Connect your slave to this local proxy instead of the real Jenkins server.

Create a custom Jenkins slave build that allows an option to specify the local port to use.

Remember also if you are using HTTPS via a self-signed certificate, you must alter the configuration jenkins-slave.xml file on the slave to specify the -noCertificateCheck option on the command line.

$(window).load is an event that fires when the DOM and all the content (everything) on the page is fully loaded like CSS, images and frames. One best example is if we want to get the actual image size or to get the details of anything we use it.

$(document).ready() indicates that code in it need to be executed once the DOM got loaded and ready to be manipulated by script. It won't wait for the images to load for executing the jQuery script.

<script type = "text/javascript">
    //$(window).load was deprecated in 1.8, and removed in jquery 3.0
    // $(window).load(function() {
    //     alert("$(window).load fired");
    // });

    $(document).ready(function() {
        alert("$(document).ready fired");
    });
</script>

$(window).load fired after the $(document).ready().

$(document).ready(function(){

}) 
//and 
$(function(){

}); 
//and
jQuery(document).ready(function(){

});

Above 3 are same, $ is the alias name of jQuery, you may face conflict if any other JavaScript Frameworks uses the same dollar symbol $. If u face conflict jQuery team provide a solution no-conflict read more.

$(window).load was deprecated in 1.8, and removed in jquery 3.0

A SELECT INTO statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found exception. If it returns more than 1 row, you'll get a too_many_rows exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO statement here.

Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID column in both tables)

BEGIN
  FOR rec IN (SELECT EMPLOYEE.EMPID, 
                     EMPLOYEE.ENAME, 
                     EMPLOYEE.DESIGNATION, 
                     EMPLOYEE.SALARY,  
                     DEPARTMENT.DEPT_NAME 
                FROM EMPLOYEE, 
                     DEPARTMENT 
               WHERE employee.departmentID = department.departmentID
                 AND EMPLOYEE.SALARY > 3000)
  LOOP
    DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
  END LOOP;
END;

I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output like this and would not depend on anyone seeing data that you write to the dbms_output buffer.

public class KeyNote
{
    public long KeyNoteId { get; set; }
    public long CourseId { get; set; }
    public string CourseName { get; set; }
    public string Note { get; set; }
    public DateTime CreatedDate { get; set; }
}

public List<KeyNote> KeyNotes { get; set; }
public List<RefCourse> GetCourses { get; set; }    

List<RefCourse> courses = KeyNotes.Select(x => new RefCourse { CourseId = x.CourseId, Name = x.CourseName }).Distinct().ToList();

By using the above logic, we can get the unique Courses.

Related answer - Below is for React.js website:

1. Install the npm module:

   npm install --save typeface-roboto-mono

2. import in .js file you want to use
   one of the below:

   import "typeface-roboto-mono"; // if import is supported
   require('typeface-roboto-mono') // if import is not supported

3. For the element you can use
   one of the below:

   fontFamily: "Roboto Mono, Menlo, Monaco, Courier, monospace", // material-ui
font-family: Roboto Mono, Menlo, Monaco, Courier, monospace; /* css */
style="font-family:Roboto Mono, Menlo, Monaco, Courier, monospace;font-weight:300;" /*inline css*/

SELECT DateAdded, COUNT(1) AS NUMBERADDBYDAY
FROM Responses
WHERE DateAdded >= dateadd(day,datediff(day,0,GetDate())- 7,0)
GROUP BY DateAdded

The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.

So, you need an alternative approach.

1). Take you current query and join the base data back on it

SELECT
  cpe.*
FROM
  Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
  (yourQuery) AS lookup
    ON  lookup.MaxData           = cpe.createdOn
    AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid

2). Use a CTE to do it all in one go...

WITH
  sequenced_data AS
(
  SELECT
    *,
    ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
  FROM
    Filteredfmgcms_claimpaymentestimate
  WHERE
    createdon < 'reportstartdate'
)
SELECT
  *
FROM
  sequenced_data
WHERE
  sequence_id = 1

NOTE: Using ROW_NUMBER() will ensure just one record per fmgcms_cpeclaimid. Even if multiple records are tied with the exact same createdon value. If you can have ties, and want all records with the same createdon value, use RANK() instead.

I just noticed that with C++20, we will have

bool std::map::contains( const Key& key ) const;

That will return true if map holds an element with key key.

You can use assign_attributes or attributes= (they're the same)

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

git reset <hash>  # you need to know the last good hash, so you can remove all your local commits

git fetch upstream
git checkout master
git merge upstream/master

voila, now your fork is back to same as upstream.

@Jk1's answer is fine, but Mockito also allows for more succinct injection using annotations:

@InjectMocks MyClass myClass; //@InjectMocks automatically instantiates too
@Mock MyInterface myInterface

But regardless of which method you use, the annotations are not being processed (not even your @Mock) unless you somehow call the static MockitoAnnotation.initMocks() or annotate the class with @RunWith(MockitoJUnitRunner.class).

I don't know if this was pointed out here. The settings for .container width have to be set on the Bootstrap website. I personally did not have to edit or touch anything within CSS files to tune my .container size which is 1600px. Under Customize tab, there are three sections responsible for media and the responsiveness of the web:

• Media queries breakpoints
• Grid system
• Container sizes

Besides Media queries breakpoints, which I believe most people refer to, I've also changed @container-desktop to (1130px + @grid-gutter-width) and @container-large-desktop to (1530px + @grid-gutter-width). Now, the .container changes its width if my browser is scaled up to ~1600px and ~1200px. Hope it can help.

//Create modal appending on body
myModalBackup = null;
$('#myModal').on('hidden.bs.modal', function(){
       $('body').append(myModalBackup.clone());
    myModalBackup = null;
});

//Destroy, clone and show modal
myModalBackup = $('#myModal').clone();
myModalBackup.find('.modal-backdrop').remove();
$('#myModal').modal('hide').remove();
myModalBackup.find('.info1').html('customize element <b>1</b>...');
myModalBackup.find('.info2').html('customize element <b>2</b>...');                             
myModalBackup.modal('show');

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

If you are dealing with a lower level time object (I often just use integers), and don't want to write a custom filter for whatever reason, an approach I use is to pass the strftime function into the template as a variable, where it can be called where you need it.

For example:

import time
context={
    'now':int(time.time()),
    'strftime':time.strftime }  # Note there are no brackets () after strftime
                                # This means we are passing in a function, 
                                # not the result of a function.

self.response.write(jinja2.render_template('sometemplate.html', **context))

Which can then be used within sometemplate.html:

<html>
    <body>
        <p>The time is {{ strftime('%H:%M%:%S',now) }}, and 5 seconds ago it was {{ strftime('%H:%M%:%S',now-5) }}.
    </body>
</html>

The mouseenter event differs from mouseover in the way it handles event bubbling. The mouseenter event, only triggers its handler when the mouse enters the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseenter/

The mouseleave event differs from mouseout in the way it handles event bubbling. The mouseleave event, only triggers its handler when the mouse leaves the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseleave/

This will work if you do not have too many expressions.

Example: ng-show="form.type === 'Limited Company' || form.type === 'Limited Partnership'"

For any more expressions than this use a controller.

In Angular 8 you can simply use "selectionChange" like this:

 <mat-select  [(value)]="selectedData" (selectionChange)="onChange()" >
  <mat-option *ngFor="let i of data" [value]="i.ItemID">
  {{i.ItemName}}
  </mat-option>
 </mat-select>

There are already a lot of good suggestions, but here's one more. You can use @JsonDeserialize to perform an arbitrary "sanitizer" which Jackson will invoke post-deserialization:

@JsonDeserialize(converter=Message1._Sanitizer.class)  
public class Message1 extends MessageBase
{
    public String string1 = "";
    public int integer1;

    public static class _Sanitizer extends StdConverter<Message1,Message1> {
        @Override
        public Message1 convert(Message1 message) {
            if (message.string1 == null) message.string1 = "";
            return message;
        }
    }
}

For almost all cases the normal list is the right choice. The arrays module is more like a thin wrapper over C arrays, which give you kind of strongly typed containers (see docs), with access to more C-like types such as signed/unsigned short or double, which are not part of the built-in types. I'd say use the arrays module only if you really need it, in all other cases stick with lists.

Using MVC5 you could use:

public enum UserPromotion
{
   None = 0x0,

   [Display(Name = "Send Job Offers By Mail")]
   SendJobOffersByMail = 0x1,

   [Display(Name = "Send Job Offers By Sms")]
   SendJobOffersBySms = 0x2,

   [Display(Name = "Send Other Stuff By Sms")]
   SendPromotionalBySms = 0x4,

   [Display(Name = "Send Other Stuff By Mail")]
   SendPromotionalByMail = 0x8
}

then if you want to create a dropdown selector you can use:

@Html.EnumDropdownListFor(expression: model => model.PromotionSelector, optionLabel: "Select") 

You have also a very good testing frameworks to create such a stub. One of my preferrable is Mockito There is also EasyMock and others... But Mockito is great you should read it - very elegant and powerfull package

I am aware this question is a bit dated, but I would like to share the method I normally use to find .c and .h files:

tree -if | grep \\.[ch]\\b | xargs -n 1 grep -H "#include"

or if you need the line number as well:

tree -if | grep \\.[ch]\\b | xargs -n 1 grep -nH "#include"
