Use merge, which is inner join by default:

pd.merge(df1, df2, left_index=True, right_index=True)

Or join, which is left join by default:

df1.join(df2)

Or concat, which is outer join by default:

pd.concat([df1, df2], axis=1)

Samples:

df1 = pd.DataFrame({'a':range(6),
                    'b':[5,3,6,9,2,4]}, index=list('abcdef'))

print (df1)
   a  b
a  0  5
b  1  3
c  2  6
d  3  9
e  4  2
f  5  4

df2 = pd.DataFrame({'c':range(4),
                    'd':[10,20,30, 40]}, index=list('abhi'))

print (df2)
   c   d
a  0  10
b  1  20
h  2  30
i  3  40

#default inner join
df3 = pd.merge(df1, df2, left_index=True, right_index=True)
print (df3)
   a  b  c   d
a  0  5  0  10
b  1  3  1  20

#default left join
df4 = df1.join(df2)
print (df4)
   a  b    c     d
a  0  5  0.0  10.0
b  1  3  1.0  20.0
c  2  6  NaN   NaN
d  3  9  NaN   NaN
e  4  2  NaN   NaN
f  5  4  NaN   NaN

#default outer join
df5 = pd.concat([df1, df2], axis=1)
print (df5)
     a    b    c     d
a  0.0  5.0  0.0  10.0
b  1.0  3.0  1.0  20.0
c  2.0  6.0  NaN   NaN
d  3.0  9.0  NaN   NaN
e  4.0  2.0  NaN   NaN
f  5.0  4.0  NaN   NaN
h  NaN  NaN  2.0  30.0
i  NaN  NaN  3.0  40.0

There is no way to create an array of a predefined size without also supplying values for the elements of that array.

The best way to initialize an array like that is array_fill. By far preferable over the various loop-and-insert solutions.

$my_array = array_fill(0, $size_of_the_array, $some_data);

Every position in the $my_array will contain $some_data.

The first zero in array_fill just indicates the index from where the array needs to be filled with the value.

Additionally, if you want the flexibility of choosing the width, you can choose between one of the following two formats (with or without truncation):

int width = 30;
// No truncation uses %-*s
printf( "%-*s %s\n", width, "Starting initialization...", "Ok." );
// Output is "Starting initialization...     Ok."

// Truncated to the specified width uses %-.*s
printf( "%-.*s %s\n", width, "Starting initialization...", "Ok." );
// Output is "Starting initialization... Ok."

If you have something like this:

t.has_key(ew)

change it to below for running on Python 3.X and above:

key = ew
if key not in t

After doing what everyone else said above, i.e.:

navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .default)
navigationController?.navigationBar.shadowImage = UIImage()
navigationController!.navigationBar.isTranslucent = true

... my navigation bar was still white. So I added this line:

navigationController?.navigationBar.backgroundColor = .clear

... et voila! That seemed to do the trick.

Probably you can go with this code to take actions as the checkbox is checked or unchecked.

$('#chk').on('click',function(){
    if(this.checked==true){
      alert('yes');
    }else{
      alert('no');
    }
});

Well, in this case the car variable will be null, so dereferencing it (as you do when you access car.length) will throw a NullPointerException.

In fact, you can't access that variable at all until some value has definitely been assigned to it - otherwise the compiler will complain that "variable car might not have been initialized".

What is it you're trying to do here (it's not clear to me exactly what "solution" you're looking for)?

For the latest jupyter notebook, (version 5) you can go to the 'help' tab in the top of the notebook and then select the option 'edit keyboard shortcuts' and add in your own customized shortcut for the 'run all' function.

pgModeler can generate nice ER diagram from PostgreSQL databases.

• https://pgmodeler.io/
• License: GPLv3

It seems there is no manual, but it is easy enough without manual. It's QT application. AFAIK, Fedora and Ubuntu has package. (pgmodeler)

In the latest version of pgModeler (0.9.1) the trial version allows you to create ERD (the design button is not disabled). To do so:

1. Click Design button to first create an empty 'design model'
2. Then click on Import and connect to the server and database you want (unless you already set that up in Manage, in which case all your databases will be available to select in step 3)
3. Import all objects (it will warn that you are importing to the current model, which is fine since it is empty).
4. Now switch back to the Design tab to see your ERD.

Here's one way:

create table #work
(
  something decimal(8,3) not null 
)

insert #work values ( 0 )
insert #work values ( 12345.6789 )
insert #work values ( 3.1415926 )
insert #work values ( 45 )
insert #work values ( 9876.123456 )
insert #work values ( -12.5678 )

select convert(varchar,convert(decimal(8,2),something))
from #work

if you want it right-aligned, something like this should do you:

select str(something,8,2) from #work

You may use this shell script below. It is able to pull files from app cache as well, not like the adb backup tool:

#!/bin/sh

if [ -z "$1" ]; then 
    echo "Sorry script requires an argument for the file you want to pull."
    exit 1
fi

adb shell "run-as com.corp.appName cat '/data/data/com.corp.appNamepp/$1' > '/sdcard/$1'"
adb pull "/sdcard/$1"
adb shell "rm '/sdcard/$1'"

Then you can use it like this:

./pull.sh files/myFile.txt
./pull.sh cache/someCachedData.txt

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount() in a React class.

For you edit, you may want to try something like this:

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

Run

npm i @types/jquery
npm install -D @types/bootstrap

in the project to add the jquery types in your Angular Project. After that include

import * as $ from "jquery";
import * as bootstrap from "bootstrap";

in your app.module.ts

Add

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

in your index.html just before the body closing tag.

And if you are running Angular 2-7 include "jquery" in the types field of tsconfig.app.json file.

This will remove all error of 'modal' and '$' in your Angular project.

You can do EXISTS in Oracle PL/SQL.

You can do the following:

DECLARE
    n_rowExist NUMBER := 0;
BEGIN
    SELECT CASE WHEN EXISTS (
      SELECT 1
      FROM person
      WHERE ID = 10
    ) THEN 1 ELSE 0 INTO n_rowExist END FROM DUAL;
    
    IF n_rowExist = 1 THEN
       -- do things when it exists
    ELSE
       -- do things when it doesn't exist
    END IF;

END;
/

Explanation:

In the query nested where it starts with SELECT CASE WHEN EXISTS and after the parenthesis (SELECT 1 FROM person WHERE ID = 10) it will return a result if it finds a person of ID of 10. If the there's a result on the query then it will assign the value of 1 otherwise it will assign the value of 0 to n_rowExist variable. Afterwards, the if statement checks if the value returned equals to 1 then is true otherwise it will be 0 = 1 and that is false.

The Substring method provides us a way to extract a particular string from the original string based on a starting position and length. If only one argument is provided, it is taken to be the starting position, and the remainder of the string is outputted.

PS > "test_string".Substring(0,4)
Test
PS > "test_string".Substring(4)
_stringPS >

link text

But this is easier...

 $s = 'Hello World is in here Hello World!'
 $p = 'Hello World'
 $s -match $p

And finally, to recurse through a directory selecting only the .txt files and searching for occurrence of "Hello World":

dir -rec -filter *.txt | Select-String 'Hello World'

Restarting the Management Studio worked for me.

• Black box testing should be the emphasis for testers/QA.
• White box testing should be the emphasis for developers (i.e. unit tests).
• The other folks who answered this question seemed to have interpreted the question as Which is more important, white box testing or black box testing. I, too, believe that they are both important but you might want to check out this IEEE article which claims that white box testing is more important.

Note that this last variable allows you to for example run Android Studio with Java 7 on OSX (which normally picks Java 6 from the version specified in Info.plist):

$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk

$ open /Applications/Android\ Studio.app

Worked for me

For me personally the main attraction of OOP programming is the ability to have self-contained classes with unexposed (private) inner workings.

What confuses me to no end in Javascript is that you can't even use function names, because you run the risk of having that same function name somewhere else in any of the external libraries that you're using.

Even though some very smart people have found workarounds for this, isn't it weird that Javascript in its purest form requires you to create code that is highly unreadable?

The beauty of OOP is that you can spend your time thinking about your app's logic, without having to worry about syntax.

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

Use required|numeric|size:11 Instead of required|min:11|numeric

My solutions in one of my own sites, with a table:

$.getJSON("sections/view_numbers_update.php", function(data) {
 $.each(data, function(index, objNumber) {
  $('#tr_' + objNumber.intID).find("td").eq(3).html(objNumber.datLastCalled);
  $('#tr_' + objNumber.intID).find("td").eq(4).html(objNumber.strStatus);
  $('#tr_' + objNumber.intID).find("td").eq(5).html(objNumber.intDuration);
  $('#tr_' + objNumber.intID).find("td").eq(6).html(objNumber.blnWasHuman);
 });
});

sections/view_numbers_update.php Returns something like:

[{"intID":"19","datLastCalled":"Thu, 10 Jan 13 08:52:20 +0000","strStatus":"Completed","intDuration":"0:04 secs","blnWasHuman":"Yes","datModified":1357807940},
{"intID":"22","datLastCalled":"Thu, 10 Jan 13 08:54:43 +0000","strStatus":"Completed","intDuration":"0:00 secs","blnWasHuman":"Yes","datModified":1357808079}]

HTML table:

<table id="table_numbers">
 <tr>
  <th>[...]</th>
  <th>[...]</th>
  <th>[...]</th>
  <th>Last Call</th>
  <th>Status</th>
  <th>Duration</th>
  <th>Human?</th>
  <th>[...]</th>
 </tr>
 <tr id="tr_123456">
  [...]
 </tr>
</table>

This essentially gives every row a unique id preceding with 'tr_' to allow for other numbered element ids, at server script time. The jQuery script then just gets this TR_[id] element, and fills the correct indexed cell with the json return.

The advantage is you could get the complete array from the DB, and either foreach($array as $record) to create the table html, OR (if there is an update request) you can die(json_encode($array)) before displaying the table, all in the same page, but same display code.

you have to call a function before it can return anything.

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction();
}

var test = mainFunction();
alert(test);

Or:

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction;
}

var test = mainFunction();
alert( test() );

for your actual code. The return should be outside, in the main function. The callback is called somewhere inside the getLocations method and hence its return value is not recieved inside your main function.

function reverseGeocode(latitude,longitude){
    var address = "";
    var country = "";
    var countrycode = "";
    var locality = "";

    var geocoder = new GClientGeocoder();
    var latlng = new GLatLng(latitude, longitude);

    geocoder.getLocations(latlng, function(addresses) {
     address = addresses.Placemark[0].address;
     country = addresses.Placemark[0].AddressDetails.Country.CountryName;
     countrycode = addresses.Placemark[0].AddressDetails.Country.CountryNameCode;
     locality = addresses.Placemark[0].AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName;
    });   
    return country
   }

For a non-commandline approach, you can open the Extensions & Updates window (Tools->Extensions and Updates) and search for the Typescript for Microsoft Visual Studio extension under Installed

    Scanner input = new Scanner(System.in);
        System.out.print("Enter number  :");
        int num = input.nextInt(); 
        System.out.print("Reverse number   :");
        int value;
        while( num > 0){
            value = num % 10;
            num  /=  10;
            System.out.print(value);  //value = Reverse
            
             }

troubleshooting-friendly style

You should not call .get() directly. Optional<>, that Stream::max returns, was designed to benefit from .orElse... inline handling.

If you are sure your arguments have their size of 2+:

list.stream()
    .map(u -> u.date)
    .max(Date::compareTo)
    .orElseThrow(() -> new IllegalArgumentException("Expected 'list' to be of size: >= 2. Was: 0"));

If you support empty lists, then return some default value, for example:

list.stream()
    .map(u -> u.date)
    .max(Date::compareTo)
    .orElse(new Date(Long.MIN_VALUE));

There is a built in method which would be the fastest method also, calling tolist on the .values np array:

df.values.tolist()

[[0.0, 3.61, 380.0, 3.0],
 [1.0, 3.67, 660.0, 3.0],
 [1.0, 3.19, 640.0, 4.0],
 [0.0, 2.93, 520.0, 4.0]]

I don't think there is way out of the box. There is no such command in DOS and batch files are far to limited to simulate it (without major pain).

Assuming that you want to group the data before you generate the key with the sequence, it sounds like you want something like

INSERT INTO HISTORICAL_CAR_STATS (
    HISTORICAL_CAR_STATS_ID, 
    YEAR,
    MONTH, 
    MAKE,
    MODEL,
    REGION,
    AVG_MSRP,
    CNT) 
SELECT MY_SEQ.nextval,
       year,
       month,
       make,
       model,
       region,
       avg_msrp,
       cnt
  FROM (SELECT '2010' year,
               '12' month,
               'ALL' make,
               'ALL' model,
               REGION,
               sum(AVG_MSRP*COUNT)/sum(COUNT) avg_msrp,
               sum(cnt) cnt
          FROM HISTORICAL_CAR_STATS
         WHERE YEAR = '2010' 
           AND MONTH = '12'
           AND MAKE != 'ALL' 
         GROUP BY REGION)

Use the call_user_func function.

There are two types of measurements you can use for specifying widths, heights, margins etc: relative and fixed.

Relative

An example of a relative measurement is percentages, which you have used. Percentages are relevant to their containing element. If there is no containing element they are relative to the window.

<div style="width:100%"> 
<!-- This div will be the full width of the browser, whatever size it is -->
    <div style="width:300px">
    <!-- this div will be 300px, whatever size the browser is -->
        <p style="width:50%">
            This paragraph's width will be 50% of it's parent (150px).
        </p>
    </div>
</div>

Another relative measurement is ems which are relative to font size.

Fixed

An example of a fixed measurement is pixels but a fixed measurement can also be pt (points), cm (centimetres) etc. Fixed (sometimes called absolute) measurements are always the same size. A pixel is always a pixel, a centimetre is always a centimetre.

If you were to use fixed measurements for your sizes the browser size wouldn't affect the layout.

There is two simples ways to do that :

1-

select("users.birthdate",
            DB::raw("FLOOR(DATEDIFF(CURRENT_DATE, STR_TO_DATE(users.birthdate, '%Y-%m-%d'))/365) AS age_way_one"),

2-

select("users.birthdate",DB::raw("(YEAR(CURDATE())-YEAR(users.birthdate)) AS age_way_two"))

Use a static Random or the numbers tend to repeat in tight/fast loops due to the system clock seeding them.

public static class RandomNumbers
{
    private static Random random = new Random();
    //=-------------------------------------------------------------------
    // double between min and the max number
    public static double RandomDouble(int min, int max) 
    {
        return (random.NextDouble() * (max - min)) + min;
    }
    //=----------------------------------
    // double between 0 and the max number
    public static double RandomDouble(int max) 
    {
        return (random.NextDouble() * max);
    }
    //=-------------------------------------------------------------------
    // int between the min and the max number
    public static int RandomInt(int min, int max) 
    {   
        return random.Next(min, max + 1);
    }
    //=----------------------------------
    // int between 0 and the max number
    public static int RandomInt(int max) 
    {
        return random.Next(max + 1);
    }
    //=-------------------------------------------------------------------
 }

Git can search diffs with the -S option (it's called pickaxe in the docs)

git log -S password

This will find any commit that added or removed the string password. Here a few options:

• -p: will show the diffs. If you provide a file (-p file), it will generate a patch for you.
• -G: looks for differences whose added or removed line matches the given regexp, as opposed to -S, which "looks for differences that introduce or remove an instance of string".
• --all: searches over all branches and tags; alternatively, use --branches[=<pattern>] or --tags[=<pattern>]

memset is generally designed to be very very fast general-purpose setting/zeroing code. It handles all cases with different sizes and alignments, which affect the kinds of instructions you can use to do your work. Depending on what system you're on (and what vendor your stdlib comes from), the underlying implementation might be in assembler specific to that architecture to take advantage of whatever its native properties are. It might also have internal special cases to handle the case of zeroing (versus setting some other value).

That said, if you have very specific, very performance critical memory zeroing to do, it's certainly possible that you could beat a specific memset implementation by doing it yourself. memset and its friends in the standard library are always fun targets for one-upmanship programming. :)

First Method

- (void)didMoveToParentViewController:(UIViewController *)parent
{
    if (![parent isEqual:self.parentViewController]) {
         NSLog(@"Back pressed");
    }
}

Second Method

-(void) viewWillDisappear:(BOOL)animated {
    if ([self.navigationController.viewControllers indexOfObject:self]==NSNotFound) {
       // back button was pressed.  We know this is true because self is no longer
       // in the navigation stack.  
    }
    [super viewWillDisappear:animated];
}

Another method is has_key() (if still using Python 2.X):

>>> a={"1":"one","2":"two"}
>>> a.has_key("1")
True

use array_map():

$yourArray = array_map('strtolower', $yourArray);

In case you need to lowercase nested array (by Yahya Uddin):

$yourArray = array_map('nestedLowercase', $yourArray);

function nestedLowercase($value) {
    if (is_array($value)) {
        return array_map('nestedLowercase', $value);
    }
    return strtolower($value);
}

1. An independent parent is the best practice for sharing configuration and options across otherwise uncoupled components. Apache has a parent pom project to share legal notices and some common packaging options.

2. If your top-level project has real work in it, such as aggregating javadoc or packaging a release, then you will have conflicts between the settings needed to do that work and the settings you want to share out via parent. A parent-only project avoids that.

3. A common pattern (ignoring #1 for the moment) is have the projects-with-code use a parent project as their parent, and have it use the top-level as a parent. This allows core things to be shared by all, but avoids the problem described in #2.

4. The site plugin will get very confused if the parent structure is not the same as the directory structure. If you want to build an aggregate site, you'll need to do some fiddling to get around this.

5. Apache CXF is an example the pattern in #2.

One thing to note that you guys are over-complicating the problem just like a lot of other posts! All you need to do is create drawable selectors with whatever backgrounds you need and set them to actual items. I just spend two hours trying your solutions (all suggested on this page) and none of them worked. Not to mention that there are tons of errors that essentially slow your performance in those try/catch blocks you have.

Anyways here is a menu xml file:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/m1"
          android:icon="@drawable/item1_selector"
          />
    <item android:id="@+id/m2"
          android:icon="@drawable/item2_selector"
          />
</menu>

Now in your item1_selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/item_highlighted" />
    <item android:state_selected="true" android:drawable="@drawable/item_highlighted" />
    <item android:state_focused="true" android:drawable="@drawable/item_nonhighlighted" />
    <item android:drawable="@drawable/item_nonhighlighted" />
</selector>

Next time you decide to go to the supermarket through Canada try google maps!

You can use:

 a.delete(a[0])   
 a.delete_at 0

Both can work

Giving us the whole error message would be much more useful. If it's for make install then you're probably trying to install something to a system directory and you're not root. If you have root access then you can run

sudo make install

or log in as root and do the whole process as root.

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

Spring-boot has a helper for this, just add

@ContextConfiguration(initializers = ConfigFileApplicationContextInitializer.class)

at the top of your test classes or an abstract test superclass.

Edit: I wrote this answer five years ago. It doesn't work with recent versions of Spring Boot. This is what I do now (please translate the Kotlin to Java if necessary):

@TestPropertySource(locations=["classpath:application.yml"])
@ContextConfiguration(
        initializers=[ConfigFileApplicationContextInitializer::class]
)

is added to the top, then

    @Configuration
    open class TestConfig {

        @Bean
        open fun propertiesResolver(): PropertySourcesPlaceholderConfigurer {
            return PropertySourcesPlaceholderConfigurer()
        }
    }

to the context.

What is this warning about?

Modern CPUs provide a lot of low-level instructions, besides the usual arithmetic and logic, known as extensions, e.g. SSE2, SSE4, AVX, etc. From the Wikipedia:

Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008 and first supported by Intel with the Sandy Bridge processor shipping in Q1 2011 and later on by AMD with the Bulldozer processor shipping in Q3 2011. AVX provides new features, new instructions and a new coding scheme.

In particular, AVX introduces fused multiply-accumulate (FMA) operations, which speed up linear algebra computation, namely dot-product, matrix multiply, convolution, etc. Almost every machine-learning training involves a great deal of these operations, hence will be faster on a CPU that supports AVX and FMA (up to 300%). The warning states that your CPU does support AVX (hooray!).

I'd like to stress here: it's all about CPU only.

Why isn't it used then?

Because tensorflow default distribution is built without CPU extensions, such as SSE4.1, SSE4.2, AVX, AVX2, FMA, etc. The default builds (ones from pip install tensorflow) are intended to be compatible with as many CPUs as possible. Another argument is that even with these extensions CPU is a lot slower than a GPU, and it's expected for medium- and large-scale machine-learning training to be performed on a GPU.

What should you do?

If you have a GPU, you shouldn't care about AVX support, because most expensive ops will be dispatched on a GPU device (unless explicitly set not to). In this case, you can simply ignore this warning by

# Just disables the warning, doesn't take advantage of AVX/FMA to run faster
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

... or by setting export TF_CPP_MIN_LOG_LEVEL=2 if you're on Unix. Tensorflow is working fine anyway, but you won't see these annoying warnings.

If you don't have a GPU and want to utilize CPU as much as possible, you should build tensorflow from the source optimized for your CPU with AVX, AVX2, and FMA enabled if your CPU supports them. It's been discussed in this question and also this GitHub issue. Tensorflow uses an ad-hoc build system called bazel and building it is not that trivial, but is certainly doable. After this, not only will the warning disappear, tensorflow performance should also improve.

Or perhaps you could use this class:

http://developer.android.com/reference/java/net/URLEncoder.html

Which is present in Android since API level 1.

Annoyingly however, it treats spaces specially (replacing them with + instead of %20). To get round this we simply use this fragment:

URLEncoder.encode(value, "UTF-8").replace("+", "%20");

Inspired by writing this answer, I ended up later expanding and writing a blog post going over this in careful detail. I recommend checking that out if you want to develop a deeper understanding of how to think about this problem--I try to explain it piece by piece, and also give a JSperf comparison at the end, going over speed considerations.

That said, The tl;dr is this: To accomplish what you're asking for (filtering and mapping within one function call), you would use Array.reduce().

However, the more readable and (less importantly) usually significantly faster² approach is to just use filter and map chained together:

[1,2,3].filter(num => num > 2).map(num => num * 2)

What follows is a description of how Array.reduce() works, and how it can be used to accomplish filter and map in one iteration. Again, if this is too condensed, I highly recommend seeing the blog post linked above, which is a much more friendly intro with clear examples and progression.

You give reduce an argument that is a (usually anonymous) function.

That anonymous function takes two parameters--one (like the anonymous functions passed in to map/filter/forEach) is the iteratee to be operated on. There is another argument for the anonymous function passed to reduce, however, that those functions do not accept, and that is the value that will be passed along between function calls, often referred to as the memo.

Note that while Array.filter() takes only one argument (a function), Array.reduce() also takes an important (though optional) second argument: an initial value for 'memo' that will be passed into that anonymous function as its first argument, and subsequently can be mutated and passed along between function calls. (If it is not supplied, then 'memo' in the first anonymous function call will by default be the first iteratee, and the 'iteratee' argument will actually be the second value in the array)

In our case, we'll pass in an empty array to start, and then choose whether to inject our iteratee into our array or not based on our function--this is the filtering process.

Finally, we'll return our 'array in progress' on each anonymous function call, and reduce will take that return value and pass it as an argument (called memo) to its next function call.

This allows filter and map to happen in one iteration, cutting down our number of required iterations in half--just doing twice as much work each iteration, though, so nothing is really saved other than function calls, which are not so expensive in javascript.

For a more complete explanation, refer to MDN docs (or to my post referenced at the beginning of this answer).

Basic example of a Reduce call:

let array = [1,2,3];
const initialMemo = [];

array = array.reduce((memo, iteratee) => {
    // if condition is our filter
    if (iteratee > 1) {
        // what happens inside the filter is the map
        memo.push(iteratee * 2); 
    }

    // this return value will be passed in as the 'memo' argument
    // to the next call of this function, and this function will have
    // every element passed into it at some point.
    return memo; 
}, initialMemo)

console.log(array) // [4,6], equivalent to [(2 * 2), (3 * 2)]

more succinct version:

[1,2,3].reduce((memo, value) => value > 1 ? memo.concat(value * 2) : memo, [])

Notice that the first iteratee was not greater than one, and so was filtered. Also note the initialMemo, named just to make its existence clear and draw attention to it. Once again, it is passed in as 'memo' to the first anonymous function call, and then the returned value of the anonymous function is passed in as the 'memo' argument to the next function.

Another example of the classic use case for memo would be returning the smallest or largest number in an array. Example:

[7,4,1,99,57,2,1,100].reduce((memo, val) => memo > val ? memo : val)
// ^this would return the largest number in the list.

An example of how to write your own reduce function (this often helps understanding functions like these, I find):

test_arr = [];

// we accept an anonymous function, and an optional 'initial memo' value.
test_arr.my_reducer = function(reduceFunc, initialMemo) {
    // if we did not pass in a second argument, then our first memo value 
    // will be whatever is in index zero. (Otherwise, it will 
    // be that second argument.)
    const initialMemoIsIndexZero = arguments.length < 2;

    // here we use that logic to set the memo value accordingly.
    let memo = initialMemoIsIndexZero ? this[0] : initialMemo;

    // here we use that same boolean to decide whether the first
    // value we pass in as iteratee is either the first or second
    // element
    const initialIteratee = initialMemoIsIndexZero ? 1 : 0;

    for (var i = initialIteratee; i < this.length; i++) {
        // memo is either the argument passed in above, or the 
        // first item in the list. initialIteratee is either the
        // first item in the list, or the second item in the list.
           memo = reduceFunc(memo, this[i]);
        // or, more technically complete, give access to base array
        // and index to the reducer as well:
        // memo = reduceFunc(memo, this[i], i, this);
    }

    // after we've compressed the array into a single value,
    // we return it.
    return memo;
}

The real implementation allows access to things like the index, for example, but I hope this helps you get an uncomplicated feel for the gist of it.

In order to get rgba integer value instead of float value, we can do

rgba = cmap(0.5,bytes=True)

So to simplify the code based on answer from Ffisegydd, the code would be like this:

#import colormap
from matplotlib import cm

#normalize item number values to colormap
norm = matplotlib.colors.Normalize(vmin=0, vmax=1000)

#colormap possible values = viridis, jet, spectral
rgba_color = cm.jet(norm(400),bytes=True) 

#400 is one of value between 0 and 1000

I tried all the above and nothing worked for me. This solved all my problems:

pip install -U numpy

pip install -U scipy

Note that the -U option to pip install requests that the package be upgraded. Without it, if the package is already installed pip will inform you of this and exit without doing anything.

version 4.6

CKEDITOR.instances.editor.getData()

Thanks to @tgrrr for a simple solution, especially when 3rd party library is not wanted (such as React-Bootstrap). However, this solution has a problem: modal container is embedded inside react component, which leads to modal-under-background issue when outside react component (or its parent element) has position style as fixed/relative/absolute. I met this problem and came up to a new solution:

"use strict";

var React = require('react');
var ReactDOM = require('react-dom');

var SampleModal = React.createClass({
  render: function() {
    return (
      <div className="modal fade" tabindex="-1" role="dialog">
        <div className="modal-dialog">
          <div className="modal-content">
            <div className="modal-header">
              <button type="button" className="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
              <h4 className="modal-title">Title</h4>
            </div>
            <div className="modal-body">
              <p>Modal content</p>
            </div>
            <div className="modal-footer">
              <button type="button" className="btn btn-default" data-dismiss="modal">Cancel</button>
              <button type="button" className="btn btn-primary">OK</button>
            </div>
          </div>
        </div>
      </div>
    );
  }
});

var sampleModalId = 'sample-modal-container';
var SampleApp = React.createClass({
  handleShowSampleModal: function() {
    var modal = React.cloneElement(<SampleModal></SampleModal>);
    var modalContainer = document.createElement('div');
    modalContainer.id = sampleModalId;
    document.body.appendChild(modalContainer);
    ReactDOM.render(modal, modalContainer, function() {
      var modalObj = $('#'+sampleModalId+'>.modal');
      modalObj.modal('show');
      modalObj.on('hidden.bs.modal', this.handleHideSampleModal);
    }.bind(this));
  },
  handleHideSampleModal: function() {
    $('#'+sampleModalId).remove();
  },
  render: function(){    
    return (
      <div>
        <a href="javascript:;" onClick={this.handleShowSampleModal}>show modal</a>
      </div>
    )
  }
});

module.exports = SampleApp;

The main idea is:

1. Clone the modal element (ReactElement object).
2. Create a div element and insert it into document body.
3. Render the cloned modal element in the newly inserted div element.
4. When the render is finished, show modal. Also, attach an event listener, so that when modal is hidden, the newly inserted div element will be removed.

>>> foo = 'BS1 1AB'
>>> foo.replace(" ", "").rstrip()[:-3].upper()
'BS1'

Update:

Django 2.2 version now has a bulk_update.

Old answer:

Refer to the following django documentation section

Updating multiple objects at once

In short you should be able to use:

ModelClass.objects.filter(name='bar').update(name="foo")

You can also use F objects to do things like incrementing rows:

from django.db.models import F
Entry.objects.all().update(n_pingbacks=F('n_pingbacks') + 1)

See the documentation.

However, note that:

• This won't use ModelClass.save method (so if you have some logic inside it won't be triggered).
• No django signals will be emitted.
• You can't perform an .update() on a sliced QuerySet, it must be on an original QuerySet so you'll need to lean on the .filter() and .exclude() methods.

If you are targeting iOS7 and already have the image split into frames you can use animatedImageNamed:duration:.

Let's say you are animating a spinner. Copy all of your frames into the project and name them as follows:

• spinner-1.png
• spinner-2.png
• spinner-3.png
• etc.,

Then create the image via:

[UIImage animatedImageNamed:@"spinner-" duration:1.0f];

From the docs:

This method loads a series of files by appending a series of numbers to the base file name provided in the name parameter. For example, if the name parameter had ‘image’ as its contents, this method would attempt to load images from files with the names ‘image0’, ‘image1’ and so on all the way up to ‘image1024’. All images included in the animated image should share the same size and scale.

The __repr__ method simply tells Python how to print objects of a class

This is how it can be done using CASE:

DECLARE @myParam INT;
SET @myParam = 1;

SELECT * 
  FROM MyTable
 WHERE 'T' = CASE @myParam
             WHEN 1 THEN 
                CASE WHEN MyColumn IS NULL THEN 'T' END
             WHEN 2 THEN
                CASE WHEN MyColumn IS NOT NULL THEN 'T' END
             WHEN 3 THEN 'T' END;

Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.

For example:

Create Table Employee(   
    Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,  
    Emp_SSN Numeric Not Null Unique,  
    Emp_FName varchar(16),   
    Emp_LName varchar(16) 
)

i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.

Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.

Select Distinct Emp_LName
From Employee

You may have many employees with the same last name, but you only want each different last name.

Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.

You could always include it using __DIR__:

include(dirname(__DIR__).'/config.php');

__DIR__ is a 'magical constant' and returns the directory of the current file without the trailing slash. It's actually an absolute path, you just have to concatenate the file name to __DIR__. In this case, as we need to ascend a directory we use PHP's dirname which ascends the file tree, and from here we can access config.php.

You could set the root path in this method too:

define('ROOT_PATH', dirname(__DIR__) . '/');

in test.php would set your root to be at the /root/ level.

include(ROOT_PATH.'config.php');

Should then work to include the config file from where you want.

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

Try something like this

    <div id=foo [href]="url" class (click)="alert('hello')" data-hello=world></div>

and then get all attributes

    const foo = document.getElementById('foo');
    // or if you have a jQuery object
    // const foo = $('#foo')[0];

    function getAttributes(el) {
        const attrObj = {};
        if(!el.hasAttributes()) return attrObj;
        for (const attr of el.attributes)
            attrObj[attr.name] = attr.value;
        return attrObj
    }

    // {"id":"foo","[href]":"url","class":"","(click)":"alert('hello')","data-hello":"world"}
    console.log(getAttributes(foo));

for array of attributes use

    // ["id","[href]","class","(click)","data-hello"]
    Object.keys(getAttributes(foo))

When you test using class inherits unittest.TestCase you can simply use methods like:

• assertTrue
• assertFalse
• assertEqual

and similar (in python documentation you find the rest).

In your example we can simply assert if mock_method.called property is False, which means that method was not called.

import unittest
from unittest import mock

import my_module

class A(unittest.TestCase):
    def setUp(self):
        self.message = "Method should not be called. Called {times} times!"

    @mock.patch("my_module.method_to_mock")
    def test(self, mock_method):
        my_module.method_to_mock()

        self.assertFalse(mock_method.called,
                         self.message.format(times=mock_method.call_count))

I was looking for "javascript prevent select change" on Google and this question comes at first result. At the end my solution was:

const $select = document.querySelector("#your_select_id");
let lastSelectedIndex = $select.selectedIndex;
// We save the last selected index on click
$select.addEventListener("click", function () {
    lastSelectedIndex = $select.selectedIndex;
});

// And then, in the change, we select it if the user does not confirm
$select.addEventListener("change", function (e) {
    if (!confirm("Some question or action")) {
        $select.selectedIndex = lastSelectedIndex;
        return;
    }
    // Here do whatever you want; the user has clicked "Yes" on the confirm
    // ...
});

I hope it helps to someone who is looking for this and does not have jQuery :)

Here is my solution, i have been reading a lot of post and they was really helpfull, finaly i build a code for small files, with cUrl and Php, that i think its really usefull.

public function postFile()
{


        $file_url = "test.txt";  //here is the file route, in this case is on same directory but you can set URL too like "http://examplewebsite.com/test.txt"
        $eol = "\r\n"; //default line-break for mime type
        $BOUNDARY = md5(time()); //random boundaryid, is a separator for each param on my post curl function
        $BODY=""; //init my curl body
        $BODY.= '--'.$BOUNDARY. $eol; //start param header
        $BODY .= 'Content-Disposition: form-data; name="sometext"' . $eol . $eol; // last Content with 2 $eol, in this case is only 1 content.
        $BODY .= "Some Data" . $eol;//param data in this case is a simple post data and 1 $eol for the end of the data
        $BODY.= '--'.$BOUNDARY. $eol; // start 2nd param,
        $BODY.= 'Content-Disposition: form-data; name="somefile"; filename="test.txt"'. $eol ; //first Content data for post file, remember you only put 1 when you are going to add more Contents, and 2 on the last, to close the Content Instance
        $BODY.= 'Content-Type: application/octet-stream' . $eol; //Same before row
        $BODY.= 'Content-Transfer-Encoding: base64' . $eol . $eol; // we put the last Content and 2 $eol,
        $BODY.= chunk_split(base64_encode(file_get_contents($file_url))) . $eol; // we write the Base64 File Content and the $eol to finish the data,
        $BODY.= '--'.$BOUNDARY .'--' . $eol. $eol; // we close the param and the post width "--" and 2 $eol at the end of our boundary header.



        $ch = curl_init(); //init curl
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                         'X_PARAM_TOKEN : 71e2cb8b-42b7-4bf0-b2e8-53fbd2f578f9' //custom header for my api validation you can get it from $_SERVER["HTTP_X_PARAM_TOKEN"] variable
                         ,"Content-Type: multipart/form-data; boundary=".$BOUNDARY) //setting our mime type for make it work on $_FILE variable
                    );
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/1.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0'); //setting our user agent
        curl_setopt($ch, CURLOPT_URL, "api.endpoint.post"); //setting our api post url
        curl_setopt($ch, CURLOPT_COOKIEJAR, $BOUNDARY.'.txt'); //saving cookies just in case we want
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); // call return content
        curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); navigate the endpoint
        curl_setopt($ch, CURLOPT_POST, true); //set as post
        curl_setopt($ch, CURLOPT_POSTFIELDS, $BODY); // set our $BODY 


        $response = curl_exec($ch); // start curl navigation

     print_r($response); //print response

}

With this we shoud be get on the "api.endpoint.post" the following vars posted You can easly test with this script, and you should be recive this debugs on the function postFile() at the last row

print_r($response); //print response

public function getPostFile()
{

    echo "\n\n_SERVER\n";
    echo "<pre>";
    print_r($_SERVER['HTTP_X_PARAM_TOKEN']);
    echo "/<pre>";
    echo "_POST\n";
    echo "<pre>";
    print_r($_POST['sometext']);
    echo "/<pre>";
    echo "_FILES\n";
    echo "<pre>";
    print_r($_FILEST['somefile']);
    echo "/<pre>";
}

Here you are it should be work good, could be better solutions but this works and is really helpfull to understand how the Boundary and multipart/from-data mime works on php and curl library,

My Best Reggards,

my apologies about my english but isnt my native language.

$element is one of four locals that $compileProvider gives to $controllerProvider which then gets given to $injector. The injector injects locals in your controller function only if asked.

The four locals are:

• $scope
• $element
• $attrs
• $transclude

The official documentation: AngularJS $compile Service API Reference - controller

The source code from Github angular.js/compile.js:

 function setupControllers($element, attrs, transcludeFn, controllerDirectives, isolateScope, scope) {
    var elementControllers = createMap();
    for (var controllerKey in controllerDirectives) {
      var directive = controllerDirectives[controllerKey];
      var locals = {
        $scope: directive === newIsolateScopeDirective || directive.$$isolateScope ? isolateScope : scope,
        $element: $element,
        $attrs: attrs,
        $transclude: transcludeFn
      };

      var controller = directive.controller;
      if (controller == '@') {

I have come accross the above issue. I have solved it as below. Its working fine for me.

1. Download the 'org.apache.commons.io.jar' file on navigating to [org.apache.commons.io.FileUtils] [ http://www.java2s.com/Code/Jar/o/Downloadorgapachecommonsiojar.htm ]

2. Extract the downloaded zip file to a specified folder.

3. Update the project properties by using below navigation Right click on project>Select Properties>Select Java Build Path> Click Libraries tab>Click Add External Class Folder button>Select the folder where zip file is extracted for org.apache.commons.io.FileUtils.zip file.

4. Now access the File Utils.

You are missing a parantheses in the denominator of your gaussian() function. As it is right now you divide by 2 and multiply with the variance (sig^2). But that is not true and as you can see of your plots the greater variance the more narrow the gaussian is - which is wrong, it should be opposit.

So just change the gaussian() function to:

def gaussian(x, mu, sig):
    return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))

Here's some advice from someone with an environment where we have folders containing tens of millions of files.

1. A folder stores the index information (links to child files & child folder) in an index file. This file will get very large when you have a lot of children. Note that it doesn't distinguish between a child that's a folder and a child that's a file. The only difference really is the content of that child is either the child's folder index or the child's file data. Note: I am simplifying this somewhat but this gets the point across.
2. The index file will get fragmented. When it gets too fragmented, you will be unable to add files to that folder. This is because there is a limit on the # of fragments that's allowed. It's by design. I've confirmed it with Microsoft in a support incident call. So although the theoretical limit to the number of files that you can have in a folder is several billions, good luck when you start hitting tens of million of files as you will hit the fragmentation limitation first.
3. It's not all bad however. You can use the tool: contig.exe to defragment this index. It will not reduce the size of the index (which can reach up to several Gigs for tens of million of files) but you can reduce the # of fragments. Note: The Disk Defragment tool will NOT defrag the folder's index. It will defrag file data. Only the contig.exe tool will defrag the index. FYI: You can also use that to defrag an individual file's data.
4. If you DO defrag, don't wait until you hit the max # of fragment limit. I have a folder where I cannot defrag because I've waited until it's too late. My next test is to try to move some files out of that folder into another folder to see if I could defrag it then. If this fails, then what I would have to do is 1) create a new folder. 2) move a batch of files to the new folder. 3) defrag the new folder. repeat #2 & #3 until this is done and then 4) remove the old folder and rename the new folder to match the old.

To answer your question more directly: If you're looking at 100K entries, no worries. Go knock yourself out. If you're looking at tens of millions of entries, then either:

a) Make plans to sub-divide them into sub-folders (e.g., lets say you have 100M files. It's better to store them in 1000 folders so that you only have 100,000 files per folder than to store them into 1 big folder. This will create 1000 folder indices instead of a single big one that's more likely to hit the max # of fragments limit or

b) Make plans to run contig.exe on a regular basis to keep your big folder's index defragmented.

Read below only if you're bored.

The actual limit isn't on the # of fragment, but on the number of records of the data segment that stores the pointers to the fragment.

So what you have is a data segment that stores pointers to the fragments of the directory data. The directory data stores information about the sub-directories & sub-files that the directory supposedly stored. Actually, a directory doesn't "store" anything. It's just a tracking and presentation feature that presents the illusion of hierarchy to the user since the storage medium itself is linear.

To initialize to current date, you could do something like:

Date firstDate = new Date();

To get it from String, you could use SimpleDateFormat like:

String dateInString = "10-Jan-2016";
SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
try {
    Date date = formatter.parse(dateInString);
    System.out.println(date);
    System.out.println(formatter.format(date));
} catch (ParseException e) {
    //handle exception if date is not in "dd-MMM-yyyy" format
}

Option A: Keyset Pagination with a Timestamp

In order to avoid the drawbacks of offset pagination you have mentioned, you can use keyset based pagination. Usually, the entities have a timestamp that states their creation or modification time. This timestamp can be used for pagination: Just pass the timestamp of the last element as the query parameter for the next request. The server, in turn, uses the timestamp as a filter criterion (e.g. WHERE modificationDate >= receivedTimestampParameter)

{
    "elements": [
        {"data": "data", "modificationDate": 1512757070}
        {"data": "data", "modificationDate": 1512757071}
        {"data": "data", "modificationDate": 1512757072}
    ],
    "pagination": {
        "lastModificationDate": 1512757072,
        "nextPage": "https://domain.de/api/elements?modifiedSince=1512757072"
    }
}

This way, you won't miss any element. This approach should be good enough for many use cases. However, keep the following in mind:

• You may run into endless loops when all elements of a single page have the same timestamp.
• You may deliver many elements multiple times to the client when elements with the same timestamp are overlapping two pages.

You can make those drawbacks less likely by increasing the page size and using timestamps with millisecond precision.

Option B: Extended Keyset Pagination with a Continuation Token

To handle the mentioned drawbacks of the normal keyset pagination, you can add an offset to the timestamp and use a so-called "Continuation Token" or "Cursor". The offset is the position of the element relative to the first element with the same timestamp. Usually, the token has a format like Timestamp_Offset. It's passed to the client in the response and can be submitted back to the server in order to retrieve the next page.

{
    "elements": [
        {"data": "data", "modificationDate": 1512757070}
        {"data": "data", "modificationDate": 1512757072}
        {"data": "data", "modificationDate": 1512757072}
    ],
    "pagination": {
        "continuationToken": "1512757072_2",
        "nextPage": "https://domain.de/api/elements?continuationToken=1512757072_2"
    }
}

The token "1512757072_2" points to the last element of the page and states "the client already got the second element with the timestamp 1512757072". This way, the server knows where to continue.

Please mind that you have to handle cases where the elements got changed between two requests. This is usually done by adding a checksum to the token. This checksum is calculated over the IDs of all elements with this timestamp. So we end up with a token format like this: Timestamp_Offset_Checksum.

For more information about this approach check out the blog post "Web API Pagination with Continuation Tokens". A drawback of this approach is the tricky implementation as there are many corner cases that have to be taken into account. That's why libraries like continuation-token can be handy (if you are using Java/a JVM language). Disclaimer: I'm the author of the post and a co-author of the library.

Use (V3 version):

(Get-Content c:\temp\test.txt).replace('[MYID]', 'MyValue') | Set-Content c:\temp\test.txt

Or for V2:

(Get-Content c:\temp\test.txt) -replace '\[MYID\]', 'MyValue' | Set-Content c:\temp\test.txt

A general solution requires parsing the URL into a RFC 2396 compliant URI (note that this is an old version of the URI standard, which java.net.URI uses).

I have written a Java URL parsing library that makes this possible: galimatias. With this library, you can achieve your desired behaviour with this code:

String urlString = //...
URLParsingSettings settings = URLParsingSettings.create()
  .withStandard(URLParsingSettings.Standard.RFC_2396);
URL url = URL.parse(settings, urlString);

Note that galimatias is in a very early stage and some features are experimental, but it is already quite solid for this use case.

Docker, basically containers, supports OS virtualization i.e. your application feels that it has a complete instance of an OS whereas VM supports hardware virtualization. You feel like it is a physical machine in which you can boot any OS.

In Docker, the containers running share the host OS kernel, whereas in VMs they have their own OS files. The environment (the OS) in which you develop an application would be same when you deploy it to various serving environments, such as "testing" or "production".

For example, if you develop a web server that runs on port 4000, when you deploy it to your "testing" environment, that port is already used by some other program, so it stops working. In containers there are layers; all the changes you have made to the OS would be saved in one or more layers and those layers would be part of image, so wherever the image goes the dependencies would be present as well.

In the example shown below, the host machine has three VMs. In order to provide the applications in the VMs complete isolation, they each have their own copies of OS files, libraries and application code, along with a full in-memory instance of an OS. Whereas the figure below shows the same scenario with containers. Here, containers simply share the host operating system, including the kernel and libraries, so they don’t need to boot an OS, load libraries or pay a private memory cost for those files. The only incremental space they take is any memory and disk space necessary for the application to run in the container. While the application’s environment feels like a dedicated OS, the application deploys just like it would onto a dedicated host. The containerized application starts in seconds and many more instances of the application can fit onto the machine than in the VM case.

Check Managing Exceptions with the Debugger page, it explains how to set this up.

Essentially, here are the steps (during debugging):

1. On the Debug menu, click Exceptions.

2. In the Exceptions dialog box, select Thrown for an entire category of exceptions, for example, Common Language Runtime Exceptions.

   -or-

   Expand the node for a category of exceptions, for example, Common Language Runtime Exceptions, and select Thrown for a specific exception within that category.

I'm not sure exactly what you want, but it sounds like it should be possible, and it also sounds like you're already on the right track.

When reseting the "Indent" of the list you have to keep in mind that browsers might have different defaults. To make life a lot easier always start off with a "Normalize" file.

The purpose of using these CSS "Normalize" files is to set everything to a know set of values and not relying on what the browser's defaults. Chrome might have a different set of defaults to say FireFox. This way you know that your pages will always display the same no matter what browser you are using, and you know the values to "Reset" your elements.

Now if you are only concerned about lists in particular I would not simply set the padding to 0, this will put your bullets "Outside" of the list not inside like you would expect.

Another thing to keep in mind is not to use the "px" or pixel unit of measurement, you want to use the "em" unit instead. The "em" unit is based on font-size, this way no matter what the font-size is you are guaranteed that the bullet will be on the inside of the list, if you use a pixel offset then on larger font sizes the bullets will be on the outside of the list.

So here is a snippet of the "Normalize" script I use. First set everything to a known value so you know what to set it back to.

ul{
   margin: 0;
   padding: 1em; /* Set the distance from the list edge to 1x the font size */
   list-style-type: disc;
   list-style-position: outside;
   list-style-image: none;
}

In date '?', the '?' is a literal string with value ?, not a parameter placeholder, so your query does not have any parameters. The date is a shorthand cast from (literal) string to date. You need to replace date '?' with ? to actually have a parameter.

Also if you know it is a date, then use setDate(..) and not setString(..) to set the parameter.

I got this error when I installed Laravel 5.5 on my digitalocean cloud server (Ubuntu 18.04 and PHP 7.2) and the following command fixed it.

First of all it's a little bit harder using just counting analysis to tell if your data is unbalanced or not. For example: 1 in 1000 positive observation is just a noise, error or a breakthrough in science? You never know.
So it's always better to use all your available knowledge and choice its status with all wise.

Okay, what if it's really unbalanced?
Once again — look to your data. Sometimes you can find one or two observation multiplied by hundred times. Sometimes it's useful to create this fake one-class-observations.
If all the data is clean next step is to use class weights in prediction model.

So what about multiclass metrics?
In my experience none of your metrics is usually used. There are two main reasons.
First: it's always better to work with probabilities than with solid prediction (because how else could you separate models with 0.9 and 0.6 prediction if they both give you the same class?)
And second: it's much easier to compare your prediction models and build new ones depending on only one good metric.
From my experience I could recommend logloss or MSE (or just mean squared error).

How to fix sklearn warnings?
Just simply (as yangjie noticed) overwrite average parameter with one of these values: 'micro' (calculate metrics globally), 'macro' (calculate metrics for each label) or 'weighted' (same as macro but with auto weights).

f1_score(y_test, prediction, average='weighted')

All your Warnings came after calling metrics functions with default average value 'binary' which is inappropriate for multiclass prediction.
Good luck and have fun with machine learning!

Edit:
I found another answerer recommendation to switch to regression approaches (e.g. SVR) with which I cannot agree. As far as I remember there is no even such a thing as multiclass regression. Yes there is multilabel regression which is far different and yes it's possible in some cases switch between regression and classification (if classes somehow sorted) but it pretty rare.

What I would recommend (in scope of scikit-learn) is to try another very powerful classification tools: gradient boosting, random forest (my favorite), KNeighbors and many more.

After that you can calculate arithmetic or geometric mean between predictions and most of the time you'll get even better result.

final_prediction = (KNNprediction * RFprediction) ** 0.5

Paul Irish has a way to do this that covers most of the common problems. See his bullet-proof @font-face article:

The final variant, which stops unnecessary data from being downloaded by IE, and works in IE8, Firefox, Opera, Safari, and Chrome looks like this:

@font-face {
  font-family: 'Graublau Web';
  src: url('GraublauWeb.eot');
  src: local('Graublau Web Regular'), local('Graublau Web'),
    url("GraublauWeb.woff") format("woff"),
    url("GraublauWeb.otf") format("opentype"),
    url("GraublauWeb.svg#grablau") format("svg");
}

He also links to a generator that will translate the fonts into all the formats you need.

As others have already specified, this will only work in the latest generation of browsers. Your best bet is to use this in conjunction with something like Cufon, and only load Cufon if the browser doesn't support @font-face.

Got a reply from @Vjeux over at the React team:

Normal HTML/CSS:

<div class="something"><span>Something</span></div>
<style>
    .something::after {
    content: '';
    position: absolute;
    -webkit-filter: blur(10px) saturate(2);
}
</style>

React with inline style:

render: function() {
    return (
        <div>
          <span>Something</span>
          <div style={{position: 'absolute', WebkitFilter: 'blur(10px) saturate(2)'}} />
        </div>
    );
},

The trick is that instead of using ::after in CSS in order to create a new element, you should instead create a new element via React. If you don't want to have to add this element everywhere, then make a component that does it for you.

For special attributes like -webkit-filter, the way to encode them is by removing dashes - and capitalizing the next letter. So it turns into WebkitFilter. Note that doing {'-webkit-filter': ...} should also work.

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

Eventhough it is an old question, this may help someone.

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

I think checking keypress events is not completely adequate, as I believe users can copy/paste into input boxes without triggering a keypress.

So onblur is probably somewhat more reliable (but is less immediate).

To truly make sure characters you don't want are not entered into input boxes (or textareas, etc.), I think you will need to

1. check keypress (if you want to give immediate feedback) and
2. also check onblur,
3. as well as validating inputs on the server (which is the only real way to make sure nothing unwanted gets into your data).

The code samples in the other answers will work fine for doing the client-side checks (just don't rely only on checking keypress events), but as was pointed out in the accepted answer, a server-side check is really required.

You add to the back state from the FragmentTransaction and remove from the backstack using FragmentManager pop methods:

FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove(myFrag);
trans.commit();
manager.popBackStack();

You can use below code snippet to read line by line, till end of file:

line = obj.readline()
while(line != ''):
    # Do Something
    line = obj.readline()

I don't know if this exists in Visual Studio 2008 but in Visual Studio 2010+ you can easily do this by:

Don't select anything, then press Ctrl + C And then (without doing anything else) Ctrl + V

    return n + (5 - n) % 5

Don't forget nullability.

ALTER TABLE <schemaName>.<tableName>
ALTER COLUMN <columnName> nvarchar(200) [NULL|NOT NULL]

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

The answer is simpler than people are making it.

There's no technical advantage either way, and "x is not y" is what everybody else uses, which makes it the clear winner. It doesn't matter that it "looks more like English" or not; everyone uses it, which means every user of Python--even Chinese users, whose language Python looks nothing like--will understand it at a glance, where the slightly less common syntax will take a couple extra brain cycles to parse.

Don't be different just for the sake of being different, at least in this field.

I just installed MySQL Server 5.7 on Windows 10 and my.ini file is located here c:\ProgramData\MySQL\MySQL Server 5.7\my.ini.

The Data folder (where your dbs are created) is here C:/ProgramData/MySQL/MySQL Server 5.7\Data.

To expand on the top-voted answer, for reference, if the you want to add more complex items to the array:

@:myArray.push(ClassMember1: "@d.ClassMember1", ClassMember2: "@d.ClassMember2");

etc.

Furthermore, if you want to pass the array as a parameter to your controller, you can stringify it first:

myArray = JSON.stringify({ 'myArray': myArray });

you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">

$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');

You can use :

const intersection = array1.filter(element => array2.includes(element));

No method can be invoked on a object which is assigned a NULL value. It will give a nullPointerException. Hence, s2.length() is giving an exception.

Please careful with $.inArray if you want to use it. I just found out that the $.inArray is only works with "Array", not with String. That's why this function will not working in IE8!

The jQuery API make confusion

The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0

--> They shouldn't say it "Similar". Since indexOf support "String" also!

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

Try something like:

import pylab as p
p.plot(x,y)
p.axis('equal')
p.show()

Note that your initial query is probably not returning what you want:

SELECT availables.bookdate AS Date, DATEDIFF(now(),availables.updated_at) as Age 
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id 
WHERE availables.bookdate BETWEEN  '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094 GROUP BY availables.bookdate

You are grouping by book date, but you are not using any grouping function on the second column of your query.

The query you are probably looking for is:

SELECT availables.bookdate AS Date, count(*) as subtotal, sum(DATEDIFF(now(),availables.updated_at) as Age)
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id
WHERE availables.bookdate BETWEEN '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094
GROUP BY availables.bookdate

Add the following to your build.gradle

apply plugin: 'eclipse'

and browse to the project directory

gradle eclipse

Once done, you could import the project from eclipse as simple Java Project.

How about this:

    string test = "01-12-12";
    try{
         DateTime dateTime = DateTime.Parse(test);
         test = dateTime.ToString("dd/yyyy");
    }
    catch (FormatException exc)
    {
        MessageBox.Show(exc.Message);
    }

Where test will be equal to "12/2012"

Hope it helps!

I was having the same problem with the AND() breaking the conditional formatting. I just happened to try treating the AND as multiplication, and it works! Remove the AND() function and just multiply your arguments. Excel will treat the booleans as 1 for true and 0 for false. I just tested this formula and it seems to work.

=(INDIRECT(ADDRESS(4,COLUMN()))>=INDIRECT(ADDRESS(ROW(),4)))*(INDIRECT(ADDRESS(4,COLUMN()))<=INDIRECT(ADDRESS(ROW(),5)))

A couple ways this can be done:

This will make it a square

ul
{
  list-style-type: square;
}

This will make it green

li
{
  color: #0F0;
}

This will prevent the text from being green

li p
{
  color: #000;
}

However that will require that all text within lists be in paragraphs so that the color is not overridden.

A better way is to make an image of a green square and use:

ul
{
  list-style: url(green-square.png);
}

Arrays.asList("Ryan", "Julie", "Bob");

Depending in who the client is, a simple protection mechanism, combined with a sensible license agreement will be far more effective than any complex licensing/encryption/obfuscation system.

The best solution would be selling the code as a service, say by hosting the service, or offering support - although that isn't always practical.

Shipping the code as .pyc files will prevent your protection being foiled by a few #s, but it's hardly effective anti-piracy protection (as if there is such a technology), and at the end of the day, it shouldn't achieve anything that a decent license agreement with the company will.

Concentrate on making your code as nice to use as possible - having happy customers will make your company far more money than preventing some theoretical piracy..

I think if you have MyEclipse, it adds a label to the Project Properties page which contains the total number of source code lines. Might not help you as MyEclipse is not free though.

Unfortunately, that wasn't enough in my case so I wrote a source analyzer to gather statistics not gathered by other solutions (for example the metrics mentioned by AlbertoPL).

I like the explanation From EdX (Microsoft: DEV210x Introduction to C++) for a similar problem:

"The enum represents the literal values of days as integers. Referring to the numeric types table, you see that an int takes 4 bytes of memory. 7 days x 4 bytes each would require 28 bytes of memory if the entire enum were stored but the compiler only uses a single element of the enum, therefore the size in memory is actually 4 bytes."

Regarding seek() there's not too much to worry about.

First of all, it is useful when operating over an open file.

It's important to note that its syntax is as follows:

fp.seek(offset, from_what)

where fp is the file pointer you're working with; offset means how many positions you will move; from_what defines your point of reference:

• 0: means your reference point is the beginning of the file
• 1: means your reference point is the current file position
• 2: means your reference point is the end of the file

if omitted, from_what defaults to 0.

Never forget that when managing files, there'll always be a position inside that file where you are currently working on. When just open, that position is the beginning of the file, but as you work with it, you may advance.
seek will be useful to you when you need to walk along that open file, just as a path you are traveling into.

You could also use INDEX MATCH, which is more "powerful" than vlookup. This would give you exactly what you are looking for:

You can leverage Apache Commons StringUtils.isEmpty(str), which checks for empty strings and handles null gracefully.

Example:

System.out.println(StringUtils.isEmpty("")); // true
System.out.println(StringUtils.isEmpty(null)); // true

Google Guava also provides a similar, probably easier-to-read method: Strings.isNullOrEmpty(str).

Example:

System.out.println(Strings.isNullOrEmpty("")); // true
System.out.println(Strings.isNullOrEmpty(null)); // true

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

You can define a Range, the size of your array and use it's value property:

Sub PrintArray(Data, SheetName As String, intStartRow As Integer, intStartCol As Integer)

    Dim oWorksheet As Worksheet
    Dim rngCopyTo As Range
    Set oWorksheet = ActiveWorkbook.Worksheets(SheetName)

    ' size of array
    Dim intEndRow As Integer
    Dim intEndCol As Integer
    intEndRow = UBound(Data, 1)
    intEndCol = UBound(Data, 2)

    Set rngCopyTo = oWorksheet.Range(oWorksheet.Cells(intStartRow, intStartCol), oWorksheet.Cells(intEndRow, intEndCol))
    rngCopyTo.Value = Data

End Sub

This question was asked before Java 7 release but now, there is another possible way using Java 7 (and above) API:

double random = ThreadLocalRandom.current().nextDouble(min, max);

nextDouble will return a pseudorandom double value between the minimum (inclusive) and the maximum (exclusive). The bounds are not necessarily int, and can be double.

I updated my requirements.txt to have psycopg2==2.7.4 --no-binary=psycopg2 So that it build binaries on source

On Windows7 I had this problem over a Samba network connection for a Java8 Jar File >80 MBytes big. Copying the file to a local drive fixed the issue.

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

I've received the same error when working in a Spring Boot Application because when running as Spring Boot, it's easy to do localhost:8080/hello/World but when you've built the artifact and deployed to Tomcat, then you need to switch to using localhost:8080/<artifactName>/hello/World

  <div class="inter">
      <p>Liste des Produits</p>
      <ul>
          <li><a href="#1">P1</a></li>

          <li><a href="#3">P3</a></li>

        $(document).ready(function(){

                alert($(this).children("a").text());
            });
        });

You just have to replace the break with a return statement.

Think of the code inside the Foreach-Object as an anonymous function. If you have loops inside the function, just use the control keywords applying to the construction (continue, break, ...).

You may be looking for the special HTML character, 
 .

You can use this to get a line break, and it can be inserted immediately following the last character in the current line. One place this is especially useful is if you want to include multiple lines in a list within a title or alt label.

Well, using the static Drawable.createFromPath(String pathName) seems a bit more straightforward to me than decoding it yourself... :-)

If your mImg is a simple ImageView, you don't even need it, use mImg.setImageUri(Uri uri) directly.

You can invoke private method with reflection. Modifying the last bit of the posted code:

Method method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);

There are a couple of caveats. First, getDeclaredMethod will only find method declared in the current Class, not inherited from supertypes. So, traverse up the concrete class hierarchy if necessary. Second, a SecurityManager can prevent use of the setAccessible method. So, it may need to run as a PrivilegedAction (using AccessController or Subject).

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

Swift 3, iOS10 solution:

open class UIInsetLabel: UILabel {

    open var insets : UIEdgeInsets = UIEdgeInsets() {
        didSet {
            super.invalidateIntrinsicContentSize()
        }
    }

    open override var intrinsicContentSize: CGSize {
        var size = super.intrinsicContentSize
        size.width += insets.left + insets.right
        size.height += insets.top + insets.bottom
        return size
    }

    override open func drawText(in rect: CGRect) {
        return super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
    }
}

You can access component one's method from component two..

componentOne

  ngOnInit() {}

  public testCall(){
    alert("I am here..");    
  }

componentTwo

import { oneComponent } from '../one.component';


@Component({
  providers:[oneComponent ],
  selector: 'app-two',
  templateUrl: ...
}


constructor(private comp: oneComponent ) { }

public callMe(): void {
    this.comp.testCall();
  }

componentTwo html file

<button (click)="callMe()">click</button>

You can use moment() and format() functions in AngularJS.

Controller:

var app = angular.module('demoApp', []);   
app.controller( 'demoCtrl', ['$scope', '$moment' function($scope , $moment) {
$scope.date = $moment().format('MM/DD/YYYY');
}]);

View:

<div ng-app="demoApp">
  <div ng-controller="demoCtrl">
    {{date}}
  </div>
</div>

From MSDN
$0 - "Substitutes the last substring matched by group number number (decimal)."

In .NET Regular expressions group 0 is always the entire match. For a literal $ you need to

string value = Regex.Replace("%PolicyAmount%", "%PolicyAmount%", @"$$0", RegexOptions.IgnoreCase);

Better to use keyword continue safe construction like this

int i=-1;
foreach (Object o in collection)
{
    ++i;
    //...
    continue; //<--- safe to call, index will be increased
    //...
}

With coffee & Jquery

  $(document).on 'keydown', (e) ->
    switch e.which
      when 37 then console.log('left key')
      when 38 then console.log('up key')
      when 39 then console.log('right key')
      when 40 then console.log('down key')
    e.preventDefault()

Dim myRow() As Data.DataRow
myRow = dt.Select("MyColumnName = 'SomeColumnTitle'")
myRow(0)("SomeOtherColumnTitle") = strValue

Code above instantiates a DataRow. Where "dt" is a DataTable, you get a row by selecting any column (I know, sounds backwards). Then you can then set the value of whatever row you want (I chose the first row, or "myRow(0)"), for whatever column you want.

I have run into this error a couple of times as well and for me the above solutions did not work. What does seem to work is going to the Project Properties, and under Compiling toggling Compile on Save.

suppose you're posting a html form with this:

<input type="text" name="username">

If using raw cgi:

import cgi
form = cgi.FieldStorage()
print form["username"]

If using Django, Pylons, Flask or Pyramid:

print request.GET['username'] # for GET form method
print request.POST['username'] # for POST form method

Using Turbogears, Cherrypy:

from cherrypy import request
print request.params['username']

Web.py:

form = web.input()
print form.username

Werkzeug:

print request.form['username']

If using Cherrypy or Turbogears, you can also define your handler function taking a parameter directly:

def index(self, username):
    print username

Google App Engine:

class SomeHandler(webapp2.RequestHandler):
    def post(self):
        name = self.request.get('username') # this will get the value from the field named username
        self.response.write(name) # this will write on the document

So you really will have to choose one of those frameworks.

I sorted this problem as verifying the json from JSONLint.com and then, correcting it. And this is code for the same.

String jsonStr = "[{\r\n" + "\"name\":\"New York\",\r\n" + "\"number\": \"732921\",\r\n"+ "\"center\": {\r\n" + "\"latitude\": 38.895111,\r\n"  + " \"longitude\": -77.036667\r\n" + "}\r\n" + "},\r\n" + " {\r\n"+ "\"name\": \"San Francisco\",\r\n" +\"number\":\"298732\",\r\n"+ "\"center\": {\r\n" + "    \"latitude\": 37.783333,\r\n"+ "\"longitude\": -122.416667\r\n" + "}\r\n" + "}\r\n" + "]";

ObjectMapper mapper = new ObjectMapper();
MyPojo[] jsonObj = mapper.readValue(jsonStr, MyPojo[].class);

for (MyPojo itr : jsonObj) {
    System.out.println("Val of name is: " + itr.getName());
    System.out.println("Val of number is: " + itr.getNumber());
    System.out.println("Val of latitude is: " + 
        itr.getCenter().getLatitude());
    System.out.println("Val of longitude is: " + 
        itr.getCenter().getLongitude() + "\n");
}

Note: MyPojo[].class is the class having getter and setter of json properties.

Result:

Val of name is: New York
Val of number is: 732921
Val of latitude is: 38.895111
Val of longitude is: -77.036667
Val of name is: San Francisco
Val of number is: 298732
Val of latitude is: 37.783333
Val of longitude is: -122.416667

It is pretty obvious that array[10] is faster than array.get(10), as the later internally does the same call, but adds the overhead for the function call plus additional checks.

Modern JITs however will optimize this to a degree, that you rarely have to worry about this, unless you have a very performance critical application and this has been measured to be your bottleneck.

[If you use Symfony 4.1.2 try this][1]

  $validDate = explode("-",$request->get('date'));
        if (checkdate(filter_var($validDate[1],FILTER_SANITIZE_NUMBER_INT),filter_var($validDate[0],FILTER_SANITIZE_NUMBER_INT),filter_var($validDate[2],FILTER_SANITIZE_NUMBER_INT))){
            $date = date_create(filter_var($request->get('date'),FILTER_SANITIZE_SPECIAL_CHARS));
        }else{
            return $this->redirectToRoute('YOUR_ROUTE');
        }

Here is another way of doing it, similar to Dan Allan's answer but without the lambda function:

>>> pd.options.display.float_format = '{:.2f}'.format
>>> Series(np.random.randn(3))
0    0.41
1    0.99
2    0.10

or

>>> pd.set_option('display.float_format', '{:.2f}'.format)

The command git config --list will list the settings. There you should also find user.name and user.email.

Your code should work as you have it see this fiddle.

You'll have to make sure your v.Dt is a proper Date object for it to work though.

{{dt | date:'yyyy-MM-dd HH:mm:ss Z'}}

or if dateFormat is defined in scope as dateFormat = 'yyyy-MM-dd HH:mm:ss Z':

{{dt | date:dateFormat }}

You can use a for-loop to address a field with $i:

ls -l | awk '{for(i=3 ; i<8 ; i++) {printf("%s\t", $i)} print ""}'

A subclass in java, is a class that inherits from another class.

Inheritance is a way for classes to add specialized behavior ontop of generalized behavior. This is often represented by the phrase "is a" relationship.

For example, a Triangle is a Shape, so it might make sense to implement a Shape class, and have the Triangle class inherit from it. In this example, Shape is the superclass of Triangle and Triangle is the subclass of Shape

Had to do it in a project without Boost. So, ended up writing my own. I will just put it on GitHub: https://github.com/corporateshark/LUrlParser

clParseURL URL = clParseURL::ParseURL( "https://name:[email protected]:80/path/res" );

if ( URL.IsValid() )
{
    cout << "Scheme    : " << URL.m_Scheme << endl;
    cout << "Host      : " << URL.m_Host << endl;
    cout << "Port      : " << URL.m_Port << endl;
    cout << "Path      : " << URL.m_Path << endl;
    cout << "Query     : " << URL.m_Query << endl;
    cout << "Fragment  : " << URL.m_Fragment << endl;
    cout << "User name : " << URL.m_UserName << endl;
    cout << "Password  : " << URL.m_Password << endl;
}

You can use method bellow

app.do_teardown_appcontext()

if(data){}

it's mean !data

• null
• undefined
• false
• ....

Stop abusing private fields!!!

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

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

There are two cases you want to extend a class:

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

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

Consider a simple library that models cars:

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

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

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

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

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

I very much support Nick's answer.

I wrote a set of scripts that provides a uniform interface for both BSD and GNU version of date.

Follow command will output the Epoch seconds for the date 2010-10-02, and it works with both BSD and GNU version of date.

$ xsh /date/convert "2010-10-02" "+%s"
1286020263

It's an equivalent of the command with GNU version of date:

date -d "2010-10-02" "+%s"

and also the command with BSD version of date:

date -j -f "%F" 2010-10-02 "+%s"

The scripts can be found at:

• https://github.com/xsh-lib/core/tree/master/functions/date

It's a part of a library called xsh-lib/core. To use them you need both repos xsh and xsh-lib/core, I list them below:

• https://github.com/alexzhangs/xsh
• https://github.com/xsh-lib/core

From Oracle 11gR2, the LISTAGG clause should do the trick:

SELECT question_id,
       LISTAGG(element_id, ',') WITHIN GROUP (ORDER BY element_id)
FROM YOUR_TABLE
GROUP BY question_id;

Beware if the resulting string is too big (more than 4000 chars for a VARCHAR2, for instance): from version 12cR2, we can use ON OVERFLOW TRUNCATE/ERROR to deal with this issue.

Scenario A: If your large files were only added to a branch, you don't need to run git filter-branch. You just need to delete the branch and run garbage collection:

git branch -D mybranch
git reflog expire --expire-unreachable=all --all
git gc --prune=all

Scenario B: However, it looks like based on your bash history, that you did merge the changes into master. If you haven't shared the changes with anyone (no git push yet). The easiest thing would be to reset master back to before the merge with the branch that had the big files. This will eliminate all commits from your branch and all commits made to master after the merge. So you might lose changes -- in addition to the big files -- that you may have actually wanted:

git checkout master
git log # Find the commit hash just before the merge
git reset --hard <commit hash>

Then run the steps from the scenario A.

Scenario C: If there were other changes from the branch or changes on master after the merge that you want to keep, it would be best to rebase master and selectively include commits that you want:

git checkout master
git log # Find the commit hash just before the merge
git rebase -i <commit hash>

In your editor, remove lines that correspond to the commits that added the large files, but leave everything else as is. Save and quit. Your master branch should only contain what you want, and no large files. Note that git rebase without -p will eliminate merge commits, so you'll be left with a linear history for master after <commit hash>. This is probably okay for you, but if not, you could try with -p, but git help rebase says combining -p with the -i option explicitly is generally not a good idea unless you know what you are doing.

Then run the commands from scenario A.

I know this question is about C#. However, you can write inline functions in .NET with F#. see: Use of `inline` in F#

concat also works nicely with a list comprehension pulled using the "loc" command against an existing dataframe

df = pd.read_csv('./data.csv') # ie; Dataframe pulled from csv file with a "userID" column

review_ids = ['1','2','3'] # ie; ID values to grab from DataFrame

# Gets rows in df where IDs match in the userID column and combines them 

dfa = pd.concat([df.loc[df['userID'] == x] for x in review_ids])

Below is python solution:

    x = []
    dic = {}
    def f(n,r):
        [a,b,c,d] = r
        if not dic.has_key((n,a,b,c,d)): dic[(n,a,b,c,d)] = 1
        if n>=25:
            if not dic.has_key((n-25,a+1,b,c,d)):f(n-25,[a+1,b,c,d])
            if not dic.has_key((n-10,a,b+1,c,d)):f(n-10,[a,b+1,c,d])
            if not dic.has_key((n-5,a,b,c+1,d)):f(n-5,[a,b,c+1,d])
            if not dic.has_key((n-1,a,b,c,d+1)):f(n-1,[a,b,c,d+1])
        elif n>=10:
            if not dic.has_key((n-10,a,b+1,c,d)):f(n-10,[a,b+1,c,d])
            if not dic.has_key((n-5,a,b,c+1,d)):f(n-5,[a,b,c+1,d])
            if not dic.has_key((n-1,a,b,c,d+1)):f(n-1,[a,b,c,d+1])
        elif n>=5:
            if not dic.has_key((n-5,a,b,c+1,d)):f(n-5,[a,b,c+1,d])
            if not dic.has_key((n-1,a,b,c,d+1)):f(n-1,[a,b,c,d+1])
        elif n>=1:
            if not dic.has_key((n-1,a,b,c,d+1)):f(n-1,[a,b,c,d+1])
        else:
            if r not in x:
                x.extend([r])

    f(100, [0,0,0,0])
    print x

I added PM2_HOME environment variable on a system level and now it works alright.

Shortest ES6+ one liner:

let exists = Object.values(obj).includes("test1");

Here is my solution:

- (void)viewDidLoad {
    [super viewDidLoad];


    self.textView.text = self.messagePlaceholderText;
    self.textView.layer.backgroundColor = [[UIColor whiteColor] CGColor];
    self.textView.layer.borderColor = [[[UIColor grayColor] colorWithAlphaComponent:0.3] CGColor];
    self.textView.layer.borderWidth = 0.5;
    self.textView.layer.cornerRadius = 5.5f;
    self.textView.layer.masksToBounds = YES;
    self.textView.textColor = [[UIColor grayColor] colorWithAlphaComponent:0.4];
}

- (void)textViewDidBeginEditing:(UITextView *)textView {
    if (textView == self.tvMessage) {
        // Delete placeholder text
        if ([self.textView.text isEqualToString:self.messagePlaceholderText]) {
            self.textView.text = @"";
            self.textView.textColor = [UIColor blackColor];
        }
    }
}

- (void)textViewDidEndEditing:(UITextView *)textView {
    if (textView == self.tvMessage) {
        // Write placeholder text
        if (self.textView.text.length == 0) {
            self.textView.text = self.messagePlaceholderText;

There is no conceivable way that the unused features in Django will give a performance penalty. Might just come in handy if you ever decide to upscale the project.

It probably means that your MySQL server is only listening the localhost interface.

If you have lines like this :

bind-address = 127.0.0.1

In your my.cnf configuration file, you should comment them (add a # at the beginning of the lines), and restart MySQL.

sudo service mysql restart

Of course, to do this, you must be the administrator of the server.

I think this is what you were looking for:

grep -E "string1|string2" filename

I think that answers like this:

grep 'string1.*string2\|string2.*string1' filename

only match the case where both are present, not one or the other or both.

Given that the XML field is named 'xmlField'...

SELECT 
[xmlField].value('(/person//firstName/node())[1]', 'nvarchar(max)') as FirstName,
[xmlField].value('(/person//lastName/node())[1]', 'nvarchar(max)') as LastName
FROM [myTable]

Step 1: open your mysql workbench application select table. choose image cell right click select "Open value in Editor"

Step 2: click on the load button and choose image file

Step 3:then click apply button

Step 4: Then apply the query to save the image .Don't forgot image data type is "BLOB". Step 5: You can can check uploaded image

Add the following:

body{
overflow-y:hidden;
}

Try the following to see if you have the proper repository installed:

# yum search java | grep 'java-'

This is going to return a list of available packages that have java in the title. Specifically we are interested in the java- anything, as the jdk will typically be in 'java-version#' type format... Anyhow, if you have to install a repo look at Dag Wieers repo:

http://dag.wieers.com/rpm/FAQ.php#B

After you've got it installed try yum search again... This time you'll have a bunch of java stuff.

# yum search java | grep 'java-'

This will return the list of the available java packages. You can install one like this:

# yum install java-1.7.0-openjdk.x86_64

I would use expr match instead of =~:

expr match "$date" "[0-9]\{8\}" >/dev/null && echo yes

This is better than the currently accepted answer of using =~ because =~ will also match empty strings, which IMHO it shouldn't. Suppose badvar is not defined, then [[ "1234" =~ "$badvar" ]]; echo $? gives (incorrectly) 0, while expr match "1234" "$badvar" >/dev/null ; echo $? gives correct result 1.

We have to use >/dev/null to hide expr match's output value, which is the number of characters matched or 0 if no match found. Note its output value is different from its exit status. The exit status is 0 if there's a match found, or 1 otherwise.

Generally, the syntax for expr is:

expr match "$string" "$lead"

Or:

expr "$string" : "$lead"

where $lead is a regular expression. Its exit status will be true (0) if lead matches the leading slice of string (Is there a name for this?). For example expr match "abcdefghi" "abc"exits true, but expr match "abcdefghi" "bcd" exits false. (Credit to @Carlo Wood for pointing out this.

2014 iframe embed on how to embed a youtube video with autoplay and no suggested videos at end of clip

rel=0&autoplay 

Example Below: .

<iframe width="640" height="360" src="//www.youtube.com/embed/JWgp7Ny3bOo?rel=0&amp;autoplay=1" frameborder="0" allowfullscreen></iframe>

textView.setTypeface(null, Typeface.BOLD_ITALIC);
textView.setTypeface(null, Typeface.BOLD);
textView.setTypeface(null, Typeface.ITALIC);
textView.setTypeface(null, Typeface.NORMAL);

To keep the previous typeface

textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC)

Make sure that all these libs are in your class path:

compile(group: 'com.sun.jersey', name: 'jersey-core',        version: '1.19.4') 
compile(group: 'com.sun.jersey', name: 'jersey-server',      version: '1.19.4') 
compile(group: 'com.sun.jersey', name: 'jersey-servlet',     version: '1.19.4')
compile(group: 'com.sun.jersey', name: 'jersey-json',        version: '1.19.4')
compile(group: 'com.sun.jersey', name: 'jersey-client',      version: '1.19.4')
compile(group: 'javax.ws.rs', name: 'jsr311-api', version: '1.1.1')
compile(group: 'org.codehaus.jackson', name: 'jackson-core-asl', version: '1.9.2')
compile(group: 'org.codehaus.jackson', name: 'jackson-mapper-asl', version: '1.9.2')
compile(group: 'org.codehaus.jackson', name: 'jackson-core-asl',   version: '1.9.2')
compile(group: 'org.codehaus.jackson', name: 'jackson-jaxrs',      version: '1.9.2')
compile(group: 'org.codehaus.jackson', name: 'jackson-xc',         version: '1.9.2')

Add "Pojo Mapping" and "Jackson Provider" to the jersey client config:

ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
clientConfig.getClasses().add(JacksonJsonProvider.class);

This solve to me!

ClientResponse response = null;

response = webResource
        .type(MediaType.APPLICATION_JSON)
        .accept(MediaType.APPLICATION_JSON)
        .get(ClientResponse.class);


if (response.getStatus() == Response.Status.OK.getStatusCode()) {

    MyClass myclass = response.getEntity(MyClass.class);
    System.out.println(myclass);
}

querySelectorAll returns a NodeList which has its own forEach method:

document.querySelectorAll('input').forEach( input => {
  // ...
});

getElementsByTagName now returns an HTMLCollection instead of a NodeList. So you would first need to convert it to an array to have access to methods like map and forEach:

Array.from(document.getElementsByTagName('input')).forEach( input => {
  // ...
});

Did you maybe use some <tab> instead of spaces?

Try remove all the spaces before the code and readd them using <space> characters, just to be sure it's not a <tab>.

if version < 8.4.0

pg_dump -D -t <table> <database>

Add -a before the -t if you only want the INSERTs, without the CREATE TABLE etc to set up the table in the first place.

version >= 8.4.0

pg_dump --column-inserts --data-only --table=<table> <database>

Use git log to obtain the hash key for specific version and then use git checkout <hashkey>

Note: Do not forget to type the hash before the last one. Last hash points your current position (HEAD) and changes nothing.

from package.A import foo

I think it's clearer than

import sys
sys.path.append("..")

Why don't use expect:

tell application "Terminal"
    activate
    set currentTab to do script ("expect -c 'spawn ssh user@IP; expect \"*?assword:*\"; send \"MySecretPass
\"; interact'")
end tell

Be aware that passing an Object with named properties as Ken suggested adds the cost of allocating and releasing the temporary object to every call. Passing normal arguments by value or reference will generally be the most efficient. For many applications though the performance is not critical but for some it can be.

The normal solution to this is to pass an instance of the context to the class as you create it, or after it is first created but before you need to use the context.

Another solution is to create an Application object with a static method to access the application context although that couples the Droid object fairly tightly into the code.

Edit, examples added

Either modify the Droid class to be something like this

 public Droid(Context context,int x, int y) {
    this.bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.birdpic);
    this.x = x;
    this.y = y;
    }   

Or create an Application something like this:

public class App extends android.app.Application
{
    private static App mApp = null;
    /* (non-Javadoc)
     * @see android.app.Application#onCreate()
     */
    @Override
    public void onCreate()
    {
        super.onCreate();
        mApp = this;
    }
    public static Context context()
    {
        return mApp.getApplicationContext();
    }
}

And call App.context() wherever you need a context - note however that not all functions are available on an application context, some are only available on an activity context but it will certainly do with your need for getResources().

Please note that you'll need to add android:name to your application definition in your manifest, something like this:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:name=".App" >

The solution that worked for me is the following one given by Steve Hansen Smythe. I am just pasting it here. Thanks Steve.

"I found another scenario in which the red exclamation mark might appear. I copied a directory from one project to another. This directory included a hidden .svn directory (the original project had been committed to version control). When I checked my new project into SVN, the copied directory still contained the old SVN information, incorrectly identifying itself as an element in its original project.

I discovered the problem by looking at the Properties for the directory, selecting SVN Info, and reviewing the Resource URL. I fixed the problem by deleting the hidden .svn directory for my copied directory and refreshing my project. The red exclamation mark disappeared, and I was able to check in the directory and its contents correctly."

You better do this syntax

if not (item in mylist):  
    Code inside the if

If you have a list of lists, you only needed to use ...

import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.

I used the code of this link http://dipaksblogonline.blogspot.com/2012/02/html5-placeholder-in-ie7-and-ie8-fixed.html

But in browser detection I used:

if (navigator.userAgent.indexOf('MSIE') > -1) {
 //Your placeholder support code here...
}

An update if one is using Express 4.2 then the timeout middleware has been removed so need to manually add it with

npm install connect-timeout

and in the code it has to be (Edited as per comment, how to include it in the code)

 var timeout = require('connect-timeout');
 app.use(timeout('100s'));

1. You can also achieve this using the backreference technique

   sed -i.bak 's/\(.*\)/\1:80/' foo.txt
   

2. You can also use with awk like this

   awk '{print $0":80"}' foo.txt > tmp && mv tmp foo.txt
   

I found a solution from from Dave Rupert / Chris Coyier. However, I wanted to make the scroll available so I came up with this:

// HTML

<div class="myIframe"> 
   <iframe> </iframe> 
</div>

// CSS

.myIframe {
     position: relative;
     padding-bottom: 65.25%;
     padding-top: 30px;
     height: 0;
     overflow: auto; 
     -webkit-overflow-scrolling:touch; //<<--- THIS IS THE KEY 
     border: solid black 1px;
} 
.myIframe iframe {
     position: absolute;
     top: 0;
     left: 0;
     width: 100%;
     height: 100%;
}

Just to enrich the discussion, if you want to move myBranch branch to your current commit, just omit the second argument after -f

Example:

git branch -f myBranch

I generally do this when I rebase while in a Detached HEAD state :)

You can refer to this site it will give you a explanation which one is better as i know {{}} this is slower than ng-bind.

I wonder why no one is suggesting routerLink and routerLinkActive (Angular 7)

<a [routerLink]="[ '/resources' ]" routerLinkActive="currentUrl!='/resources'">

I removed the href and now using this. When using href, it was going to the base url or reloading the same route again.

First installed sudo apt-get install php5-gd, then sudo apt-get install php5-intl and last one was sudo apt-get install php5-xsl. After that, it's installing as it should.
