I might be very late but encoutered this problem sometime before and saw this link. Thanks . Please check this shall work.

typeof is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.

GetType() is a method you call on individual objects, to get the execution-time type of the object.

Note that unless you only want exactly instances of TextBox (rather than instances of subclasses) you'd usually use:

if (myControl is TextBox)
{
    // Whatever
}

Or

TextBox tb = myControl as TextBox;
if (tb != null)
{
    // Use tb
}

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

int max = 50;
int min = 1;

1. Using Math.random()

double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);

This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double

Why?

random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.

2. Using Random class in Java.

Random rand = new Random(); 
int value = rand.nextInt(50); 

This will give value from 0 to 49.

For 1 to 50: rand.nextInt((max - min) + 1) + min;

Source of some Java Random awesomeness.

just use this,

utf8_encode($string);

you've to replace your $arr with $string.

I think it will work...try this.

As others have noted, it is usually preferable to specify a minimum logging level to log that level and any others more severe than it. It seems like you are just thinking about the logging levels backwards.

However, if you want more fine-grained control over logging individual levels, you can tell log4net to log only one or more specific levels using the following syntax:

<filter type="log4net.Filter.LevelMatchFilter">
  <levelToMatch value="WARN"/>
</filter>

Or to exclude a specific logging level by adding a "deny" node to the filter.

You can stack multiple filters together to specify multiple levels. For instance, if you wanted only WARN and FATAL levels. If the levels you wanted were consecutive, then the LevelRangeFilter is more appropriate.

Reference Doc: log4net.Filter.LevelMatchFilter

If the other answers haven't given you enough information, hopefully this will help you get what you want out of log4net.

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

tl;dr

I contrast them in two ways:

joins - For conditional selection of records.

includes - When using an association on each member of a result set.

Longer version

Joins is meant to filter the result set coming from the database. You use it to do set operations on your table. Think of this as a where clause that performs set theory.

Post.joins(:comments)

is the same as

Post.where('id in (select post_id from comments)')

Except that if there are more than one comment you will get duplicate posts back with the joins. But every post will be a post that has comments. You can correct this with distinct:

Post.joins(:comments).count
=> 10
Post.joins(:comments).distinct.count
=> 2

In contract, the includes method will simply make sure that there are no additional database queries when referencing the relation (so that we don't make n + 1 queries)

Post.includes(:comments).count
=> 4 # includes posts without comments so the count might be higher.

The moral is, use joins when you want to do conditional set operations and use includes when you are going to be using a relation on each member of a collection.

I've found that in JavaScript a simple way to convert a string to a number is to multiply it by 1. It resolves the concatenation problem, because the "+" symbol has multiple uses in JavaScript, while the "*" symbol is purely for mathematical multiplication.

Based on what I've seen here regarding PHP automatically being willing to interpret a digit-containing string as a number (and the comments about adding, since in PHP the "+" is purely for mathematical addition), this multiply trick works just fine for PHP, also.

I have tested it, and it does work... Although depending on how you acquired the string, you might want to apply the trim() function to it, before multiplying by 1.

Actually I cannot reproduce the problem. The script as written in the question works fine, except for the case where $1 is empty.

However, there is a problem in the script related to redirection of stderr. Although the two forms &> and >& exist, in your case you want to use >&. You already redirected stdout, that's why the form &> does not work. You can easily verify it this way:

getent /etc/passwd username >/dev/null 2&>1
ls

You will see a file named 1 in the current directory. You want to use 2>&1 instead, or use this:

getent /etc/passwd username &>/dev/null

This also redirects stdout and stderr to /dev/null.

Warning Redirecting stderr to /dev/null might not be such a good idea. When things go wrong, you will have no clue why.

Before you return your model from the controller, set your ReturnDate property to DateTime.Now()

myModel.ReturnDate = DateTime.Now()

return View(myModel)

Your view is not the right place to set values on properties so the controller is the better place for this.

You could even have it so that the getter on ReturnDate returns the current date/time.

private DateTime _returnDate = DateTime.MinValue;
public DateTime ReturnDate{
   get{
     return (_returnDate == DateTime.MinValue)? DateTime.Now() : _returnDate;
   }
   set{_returnDate = value;}
}

mysql_real_escape_string() or str_replace() function will help you to solve your problem.

WHERE created_date >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) 
  AND created_date <= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 1 MONTH)), INTERVAL 0 DAY) 

This worked for me (Selects all records created from last month, regardless of the day you run the query this month)

You need to split the line first.

import csv

with open('log.txt', 'r') as in_file:
    stripped = (line.strip() for line in in_file)
    lines = (line.split(",") for line in stripped if line)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro'))
        writer.writerows(lines)

To do that you should do:

a =  [5, 7, 11, 4, 5]
for i in range(len(a)-1):
    print [a[i], a[i+1]]

You can start with a google sheet set up with a main page and drop down source page like shown below.

You can set up the first column drop down through the normal Data > Validations menu prompts.

Main Page

Drop Down Source Page

After that, you need to set up a script with the name onEdit. (If you don't use that name, the getActiveRange() will do nothing but return cell A1)

And use the code provided here:

function onEdit() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = SpreadsheetApp.getActiveSheet();
  var myRange = SpreadsheetApp.getActiveRange();
  var dvSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Categories");
  var option = new Array();
  var startCol = 0;

  if(sheet.getName() == "Front Page" && myRange.getColumn() == 1 && myRange.getRow() > 1){
    if(myRange.getValue() == "Category 1"){
      startCol = 1;
    } else if(myRange.getValue() == "Category 2"){
      startCol = 2;
    } else if(myRange.getValue() == "Category 3"){
      startCol = 3;
    } else if(myRange.getValue() == "Category 4"){
      startCol = 4;
    } else {
      startCol = 10
    }

  if(startCol > 0 && startCol < 10){
    option = dvSheet.getSheetValues(3,startCol,10,1);
    var dv = SpreadsheetApp.newDataValidation();
    dv.setAllowInvalid(false);  
    //dv.setHelpText("Some help text here");
    dv.requireValueInList(option, true);
    sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).setDataValidation(dv.build());
   }

  if(startCol == 10){
    sheet.getRange(myRange.getRow(),myRange.getColumn() + 1).clearDataValidations();
  } 
  }
}

After that, set up a trigger in the script editor screen by going to Edit > Current Project Triggers. This will bring up a window to have you select various drop downs to eventually end up at this:

You should be good to go after that!

Here is how removed special characters.

I simply applied regex

Dim strPattern As String: strPattern = "[^a-zA-Z0-9]" 'The regex pattern to find special characters
Dim strReplace As String: strReplace = "" 'The replacement for the special characters
Set regEx = CreateObject("vbscript.regexp") 'Initialize the regex object    
Dim GCID As String: GCID = "Text #N/A" 'The text to be stripped of special characters

' Configure the regex object
With regEx
    .Global = True
    .MultiLine = True
    .IgnoreCase = False
    .Pattern = strPattern
End With

' Perform the regex replacement
GCID = regEx.Replace(GCID, strReplace)

It is very convenient to use train_test_split without performing reindexing after dividing to several sets and not writing some additional code. Best answer above does not mention that by separating two times using train_test_split not changing partition sizes won`t give initially intended partition:

x_train, x_remain = train_test_split(x, test_size=(val_size + test_size))

Then the portion of validation and test sets in the x_remain change and could be counted as

new_test_size = np.around(test_size / (val_size + test_size), 2)
# To preserve (new_test_size + new_val_size) = 1.0 
new_val_size = 1.0 - new_test_size

x_val, x_test = train_test_split(x_remain, test_size=new_test_size)

In this occasion all initial partitions are saved.

There is no way to know unless the particular company reveals the info. The best you can do is find a few companies that are sharing and then extrapolate based on app ranking (which is available publicly). The best you'll get is a ball park estimate.

Extending answers above, when you got joined strings, not added/subtracted position (e.g. "37.12340-0.00069"), convert your original lat/longitude to floats, e.g. using parseFloat(), then add or subtract corrections.

In case anyone else has the same issue as this on

Both git merge --squash and git rebase --interactive can produce a "squashed" commit.
But they serve different purposes.

• git merge --squash abranch

will produce a squashed commit on the destination branch, without marking any merge relationship.
(Note: it does not produce a commit right away: you need an additional git commit -m "squash branch")
This is useful if you want to throw away the source branch completely, going from (schema taken from SO question):

 git checkout stable

      X                   stable
     /                   
a---b---c---d---e---f---g tmp

to:

git merge --squash tmp
git commit -m "squash tmp"

      X-------------------G stable
     /                   
a---b---c---d---e---f---g tmp

and then deleting tmp branch.

Note: git merge has a --commit option, but it cannot be used with --squash. It was never possible to use --commit and --squash together.
Since Git 2.22.1 (Q3 2019), this incompatibility is made explicit:

See commit 1d14d0c (24 May 2019) by Vishal Verma (reloadbrain).
^{(Merged by Junio C Hamano -- gitster -- in commit 33f2790, 25 Jul 2019)}

merge: refuse --commit with --squash

Previously, when --squash was supplied, 'option_commit' was silently dropped. This could have been surprising to a user who tried to override the no-commit behavior of squash using --commit explicitly.

git/git builtin/merge.c#cmd_merge() now includes:

if (option_commit > 0)
    die(_("You cannot combine --squash with --commit."));

• git rebase --interactive

replays some or all of your commits on a new base, allowing you to squash (or more recently "fix up", see this SO question), going directly to:

git checkout tmp
git rebase -i stable

      stable
      X-------------------G tmp
     /                     
a---b

If you choose to squash all commits of tmp (but, contrary to merge --squash, you can choose to replay some, and squashing others).

So the differences are:

• squash does not touch your source branch (tmp here) and creates a single commit where you want.
• rebase allows you to go on on the same source branch (still tmp) with:
  • a new base
  • a cleaner history

Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:

1. Checkout

   git checkout --orphan latest_branch

2. Add all the files

   git add -A

3. Commit the changes

   git commit -am "commit message"

4. Delete the branch

   git branch -D main

5. Rename the current branch to main

   git branch -m main

6. Finally, force update your repository

   git push -f origin main

PS: this will not keep your old commit history around

document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';

@Service: It tells that particular class is a Service to the client. Service class contains mainly business Logic. If you have more Service classes in a package than provide @Qualifier otherwise it should not require @Qualifier.

Case 1:

@Service("employeeService")
public class EmployeeServiceImpl implements EmployeeService{
}

Case2:

@Service
public class EmployeeServiceImpl implements EmployeeService{
}

both cases are working...

You can close your form after some execution..

//YourForm.ActiveForm.Close();

    LoadingForm.ActiveForm.Close();

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

I picked up the content using JavaScript and created a window that I could print in stead...

I've needed this and after some research I came up with this (jQuery needed):

First, right after the <body> tag add this:

<div id="loading">
  <img id="loading-image" src="images/ajax-loader.gif" alt="Loading..." />
</div>

Then add the style class for the div and image to your CSS:

#loading {
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  position: fixed;
  display: block;
  opacity: 0.7;
  background-color: #fff;
  z-index: 99;
  text-align: center;
}

#loading-image {
  position: absolute;
  top: 100px;
  left: 240px;
  z-index: 100;
}

Then, add this javascript to your page (preferably at the end of your page, before your closing </body> tag, of course):

<script>
  $(window).load(function() {
    $('#loading').hide();
  });
</script>

Finally, adjust the position of the loading image and the background-colour of the loading div with the style class.

This is it, should work just fine. But of course you have to have an ajax-loader.gif somewhere. Freebies here. (Right-click > Save Image As...)

A simple way is to add

.center_div{
    margin: 0 auto;
    width:80% /* value of your choice which suits your alignment */
}

to you class .container.Add width:xx % to it and you get perfectly centered div!

eg :

<div class="container center_div">

but i feel that by default container is centered in BS!

My guess is that here

<context:component-scan base-package="pl.com.radzikowski.webmail" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>

all annotations are first disabled by use-default-filters="false" and then only @Controller annotation enabled. Thus, your @Component annotation is not enabled.

You can use the iterator remove() function to remove the object from underlying collection object. But in this case you can remove the same object and not any other object from the list.

follow these steps. 1:- create your configuration class like below you can see

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.beans.factory.annotation.Value;

@Configuration
public class YourConfiguration{

    // passing the key which you set in application.properties
    @Value("${some.pro}")
    private String somePro;

   // getting the value from that key which you set in application.properties
    @Bean
    public String getsomePro() {
        return somePro;
    }
}

2:- when you have a configuration class then inject in the variable from a configuration where you need.

@Component
public class YourService {

    @Autowired
    private String getsomePro;

    // now you have a value in getsomePro variable automatically.
}

RD stands for REMOVE Directory.

/S : Delete all files and subfolders in addition to the folder itself. Use this to remove an entire folder tree.

/Q : Quiet - do not display YN confirmation

Example :

RD /S /Q C:/folder_path/here

I use this and it works right

@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
    return this.idOdon;
}

Add keyword static to class declaration:

// this is a non-generic static class
public static class LinqHelper
{
}

 <style name="WhiteTextWithShadow" parent="@android:style/TextAppearance">
    <item name="android:shadowDx">1</item>
    <item name="android:shadowDy">1</item>
    <item name="android:shadowRadius">1</item>
    <item name="android:shadowColor">@android:color/black</item>
    <item name="android:textColor">@android:color/white</item>
</style>

then use as

 <TextView
            android:id="@+id/text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="15sp"
            tools:text="Today, May 21"
            style="@style/WhiteTextWithShadow"/>

You want the output to print the given statement if and only if the number falls between 10,000 and 30,000.

Code should be;

if number >= 10000 and number <= 30000:
    print("you have to pay 5% taxes")

As it is already explained in other answers, const in C merely means that a variable is read-only. It is still a run-time value. However, you can use an enum as a real constant in C:

enum { NUM_TYPES = 4 };
static int types[NUM_TYPES] = { 
  1, 2, 3, 4
};

Adding a directory to subversion, and ignoring the directory contents

svn propset svn:ignore '\*.*' .

or

svn propset svn:ignore '*' .

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;

It sounds like probability density estimation problem to me.

from scipy.stats import gaussian_kde
occurences = [0,0,0,0,..,1,1,1,1,...,2,2,2,2,...,47]
values = range(0,48)
kde = gaussian_kde(map(float, occurences))
p = kde(values)
p = p/sum(p)
print "P(x>=1) = %f" % sum(p[1:])

Also see http://jpktd.blogspot.com/2009/03/using-gaussian-kernel-density.html.

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

In Java 8

public String[] concat(String[] arr1, String[] arr2){
    Stream<String> stream1 = Stream.of(arr1);
    Stream<String> stream2 = Stream.of(arr2);
    Stream<String> stream = Stream.concat(stream1, stream2);
    return Arrays.toString(stream.toArray(String[]::new));
}

You can use Arrays.fill(array, -1).

An additional suggestion.

You can leverage nosetests and pdb together, rather injecting pdb.set_trace() in your views manually. The advantage is that you can observe error conditions when they first start, potentially in 3rd party code.

Here's an error for me today.

TypeError at /db/hcm91dmo/catalog/records/

render_option() argument after * must be a sequence, not int

....


Error during template rendering

In template /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/crispy_forms/templates/bootstrap3/field.html, error at line 28

      {% if field|is_checkbox and form_show_labels %}

Now, I know this means that I goofed the constructor for the form, and I even have good idea of which field is a problem. But, can I use pdb to see what crispy forms is complaining about, within a template?

Yes, I can. Using the --pdb option on nosetests:

tests$ nosetests test_urls_catalog.py --pdb

As soon as I hit any exception (including ones handled gracefully), pdb stops where it happens and I can look around.

(Pdb)         

Now, it's clear that my choices argument to the crispy field constructor was as it was a list within a list, rather than a list/tuple of tuples.

 'choices': [[('_', 'any type'), (7, (7, 'type 7', 'RECTYPE_TABLE'))]]

The neat thing is that this pdb is taking place within crispy's code, not mine and I didn't need to insert it manually.

I hope this will help somebody, I solved the problem like this

There was a problem because the database was not open. Command startup opens the database.

This you can solve with command alter database open in some case with alter database open resetlogs

$ sqlplus / sysdba

It does work with me. Make sure that you append ".txt" next to timeLog. I used it in a simple program opened with Netbeans and it writes the program in the main folder (where builder and src folders are).

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.

C++ uses structs primarily for 1) backwards compatibility with C and 2) POD types. C structs do not have methods, inheritance or visibility.

Use a shell script:

#!/bin/bash
# myscript
FOO=bar
somecommand someargs | somecommand2

> ./myscript

double *ptr = malloc(sizeof(double *) * TIME);
/* ... */
for(tcount = 0; tcount <= TIME; tcount++)
                         ^^

• You're overstepping the array. Either change <= to < or alloc SIZE + 1 elements
• Your malloc is wrong, you'll want sizeof(double) instead of sizeof(double *)
• As ouah comments, although not directly linked to your corruption problem, you're using *(ptr+tcount) without initializing it

• Just as a style note, you might want to use ptr[tcount] instead of *(ptr + tcount)
• You don't really need to malloc + free since you already know SIZE

Use the jQueryify booklet:

Instead of copy pasting the code in the other answers, this'll make it a clickable bookmark.

Dates should be used as immutable points in time; Calendars are mutable, and can be passed around and modified if you need to collaborate with other classes to come up with a final date. Consider them analogous to String and StringBuilder and you'll understand how I consider they should be used.

(And yes, I know Date isn't actually technically immutable, but the intention is that it should not be mutable, and if nothing calls the deprecated methods then it is so.)

You could simply add a click listener on the map inside the function that creates the InfoWindow

google.maps.event.addListener(marker, 'click', function() {
    var infoWindow = createInfoWindowForMarker(marker);
    infoWindow.open(map, marker);
    google.maps.event.addListener(map, 'click', function() {
        infoWindow.close();
    });
});

The slick-slide has inner wrapping div which you can use to create spacing between slides without breaking the design:

.slick-list {margin: 0 -5px;}
.slick-slide>div {padding: 0 5px;}

SELECT
  student.firstname,
  student.lastname,
  exam.name,
  exam.date,
  grade.grade
FROM grade
 INNER JOIN student
   ON student.studentId = grade.fk_studentId
 INNER JOIN exam
   ON exam.examId = grade.fk_examId
 GROUP BY grade.gradeId
 ORDER BY exam.date

Use the Bootstrap Customizer to generate a version of Bootstrap that has a taller navbar. The value you want to change is @navbar-height in the Navbar section.

Inspect your current implementation to see how tall your navbar is with the 50px brand image, and use that calculated height in the Customizer.

In bash, we use

declare -A name_of_dictonary_variable

so that Bash understands it is a dictionary.

For e.g. you want to create sounds dictionary then,

declare -A sounds

sounds[dog]="Bark"

sounds[wolf]="Howl"

where dog and wolf are "keys", and Bark and Howl are "values".

You can access all values using : echo ${sounds[@]} OR echo ${sounds[*]}

You can access all keys only using: echo ${!sounds[@]}

And if you want any value for a particular key, you can use:

${sounds[dog]}

this will give you value (Bark) for key (Dog).

I know that you can modify a javascript file when using Google Chrome.

1. Open up Chrome Inspector, go to the "Scripts" tab.
2. Press the drop-down menu and select the javascript file that you want to edit.
3. Double click in the text field, type in what ever you want and delete whatever you want.
4. Then all you have to do is press Ctrl + S to save the file.

Warning: If you refresh the page, all changes will go back to original file. I recommend to copy/paste the code somewhere else if you want to use it again.

Hope this helps!

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

Use the S3FileSystem.rm function in s3fs.

You can delete a single file or several at once:

import s3fs
file_system = s3fs.S3FileSystem()

file_system.rm('s3://my-bucket/foo.txt')  # single file

files = ['s3://my-bucket/bar.txt', 's3://my-bucket/baz.txt']
file_system.rm(files)  # several files

I tried various javascript/jQuery-based strategies, but I kept having issues. The latest issue to arise involved accidental submission when the user uses the enter key to select from the browser's built-in auto-complete list. I finally switched to this strategy, which seems to work on all the browsers my company supports:

<div class="hidden-submit"><input type="submit" tabindex="-1"/></div>

.hidden-submit {
    border: 0 none;
    height: 0;
    width: 0;
    padding: 0;
    margin: 0;
    overflow: hidden;
}

This is similar to the currently-accepted answer by Chris Marasti-Georg, but by avoiding display: none, it appears to work correctly on all browsers.

Update

I edited the code above to include a negative tabindex so it doesn't capture the tab key. While this technically won't validate in HTML 4, the HTML5 spec includes language to make it work the way most browsers were already implementing it anyway.

You can implement error-specific logic as follows:

error: function (XMLHttpRequest, textStatus, errorThrown) {
    if (textStatus == 'Unauthorized') {
        alert('custom message. Error: ' + errorThrown);
    } else {
        alert('custom message. Error: ' + errorThrown);
    }
}

grep '^..' my_file

example

THIS

IS

THE

FILE

EOF_MYFILE

it gives as output only lines with at least 2 characters.

THIS
IS
THE
FILE
EOF_MYFILE

See also the results with grep '^' my_file outputs

THIS

IS

THE

FILE

EOF_MYFILE

and also with grep '^.' my_file outputs

THIS
IS
THE
FILE
EOF_MYFILE

You can also try using strpbrk() for the negation (none of the letters have been found):

$find_letters = array('a', 'c', 'd');
$string = 'abcdefg';

if(strpbrk($string, implode($find_letters)) === false)
{
    echo 'None of these letters are found in the string!';
}

I want to propose other one with using $.each:

1. We may to declare ajax function like:

   function ajaxFn(someData) {
       this.someData = someData;
       var that = this;
       return function () {
           var promise = $.Deferred();
           $.ajax({
               method: "POST",
               url: "url",
               data: that.someData,
               success: function(data) {
                   promise.resolve(data);
               },
               error: function(data) {
                   promise.reject(data);
               }
           })
           return promise;
       }
   }
   

2. Part of code where we creating array of functions with ajax to send:

   var arrayOfFn = [];
   for (var i = 0; i < someDataArray.length; i++) {
       var ajaxFnForArray = new ajaxFn(someDataArray[i]);
       arrayOfFn.push(ajaxFnForArray);
   }
   

3. And calling functions with sending ajax:

   $.when(
       $.each(arrayOfFn, function(index, value) {
           value.call()
       })
   ).then(function() {
           alert("Cheer!");
       }
   )
   

compact_blank (Rails 6.1+)

If you are using Rails (or a standalone ActiveSupport), starting from version 6.1, there is a compact_blank method which removes blank values from hashes.

It uses Object#blank? under the hood for determining if an item is blank.

{ a: "", b: 1, c: nil, d: [], e: false, f: true }.compact_blank
# => { b: 1, f: true }

Here is a link to the docs and a link to the relative PR.

A destructive variant is also available. See Hash#compact_blank!.

If you need to remove only nil values,

please, consider using Ruby build-in Hash#compact and Hash#compact! methods.

{ a: 1, b: false, c: nil }.compact
# => { a: 1, b: false }

You convert the hex string to a byte array.

public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
                 .Where(x => x % 2 == 0)
                 .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                 .ToArray();
}

And then use WriteAllBytes to write to the file system.

I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.

I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:

    $('.start').keyup(function() {
        var otherInputs = $(this).parents('td').siblings().find('input');

        for(var i = 0; i < otherInputs.length; i++) {
            alert($(otherInputs[i]).val());
        }
        return false;
    });

If like me you recently moved certain classes to different packages ect. and you use android navigation. Make sure to change the argType to you match you new package address. from:

app:argType="com.example.app.old.Item" 

to:

app:argType="com.example.app.new.Item" 

Well I found the solution. It can be done one by passing a closure function in with() as second index of array like

Post::query()
    ->with(array('user' => function($query) {
        $query->select('id','username');
    }))
    ->get();

It will only select id and username from other table. I hope this will help others.

Remember that the primary key (id in this case) needs to be the first param in the $query->select() to actually retrieve the necessary results.*

All third=party tools mentioned below are 100% free.

I’ve used ApexSQL Search with good success for searching both objects and data in tables. It comes with several other features such as relationship diagrams and such…

I was a bit slow on large (40GB TFS Database) databases though…

Apart from this there is also SSMS Tools pack that offers a lot of other features that are quite useful even though these are not directly related to searching text.

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Besides executeUpdate() on the parentheses, you must also add a variable to use an SQL statement.

For example:

PreparedStatement pst =  connection.prepareStatement(sql);
int numRowsChanged = pst.executeUpdate(sql);

One of the alternative solution is to use a container orchestration solution like Kubernetes. Kubernetes has support for init containers which run to completion before other containers can start. You can find an example here with SQL Server 2017 Linux container where API container uses init container to initialise a database

https://www.handsonarchitect.com/2018/08/understand-kubernetes-object-init.html

Another possible reason for the message:

can't load package: .... : no buildable Go source files

Is when the source files being compiled have:

// +build ignore

In which case the files are ignored and not buildable as requested.This behaviour is documented at https://golang.org/pkg/go/build/

I'm sure Don Box created SOAP as a joke - 'look you can call RPC methods over the web' and today groans when he realises what a bloated nightmare of web standards it has become :-)

REST is good, simple, implemented everywhere (so more a 'standard' than the standards) fast and easy. Use REST.

You really should try to use screen. It is a bit more complicated than just doing nohup long_running &, but understanding screen once you never come back again.

Start your screen session at first:

user@host:~$ screen

Run anything you want:

wget http://mirror.yandex.ru/centos/4.6/isos/i386/CentOS-4.6-i386-binDVD.iso

Press ctrl+A and then d. Done. Your session keeps going on in background.

You can list all sessions by screen -ls, and attach to some by screen -r 20673.pts-0.srv command, where 0673.pts-0.srv is an entry list.

The Problem is the "as string" in your function. Replace it with "as double" or "as long" to make it work. This way it even works if the last row is bigger than the "large number" proposed in the accepted answer.

So this should work

Function ultimaFilaBlanco(col As double) As Long        
    Dim lastRow As Long
    With ActiveSheet
        lastRow = ActiveSheet.Cells(ActiveSheet.Rows.Count, col).End(xlUp).row
    End With            
    ultimaFilaBlanco = lastRow          
End Function

This is the easiest way.

I did not need to open a new notebook. Instead, I reopened the tree, and reconnected the kernel. At some point I also restarted the kernel. – user650654 Oct 9 '19 at 0:17

How about this:

my_hash = HashWithIndifferentAccess.new(YAML.load_file('yml'))

# my_hash['key'] => "val"
# my_hash[:key]  => "val"

Go to Run type services.msc. Check whether or not MySQL services are running. If not, start it manually. Once it is started, type MySQL Show to test the service.

I have found a good work-around for continue (love the break sample above). Here I do not want to list "agency". In PHP I'd "continue" but in twig, I came up with alternative:

{% for basename, perms in permsByBasenames %} 
    {% if basename == 'agency' %}
        {# do nothing #}
    {% else %}
        <a class="scrollLink" onclick='scrollToSpot("#{{ basename }}")'>{{ basename }}</a>
    {% endif %}
{% endfor %}

OR I simply skip it if it doesn't meet my criteria:

{% for tr in time_reports %}
    {% if not tr.isApproved %}
        .....
    {% endif %}
{% endfor %}

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

$(function(){
    $('form').sumbit{
        $('this').serialize();
    }
});

In jQuery, the above code would give you the URL string with POST parameters in the URL. It's not impossible to extract the POST parameters.

To use jQuery, you need to include the jQuery library. Use the following for that:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js" type="text/javascript"></script>

This is what fixed it for me:

max-height: 100%;
overflow-y: auto;

EDIT: I now use the same method currently used on Twitter where the modal acts sort of like a separate page on top of the current content and the content behind the modal does not move as you scroll.

In essence it is this:

var scrollBarWidth = window.innerWidth - document.body.offsetWidth;
$('body').css({
  marginRight: scrollBarWidth,
  overflow: 'hidden'
});
$modal.show();

With this CSS on the modal:

position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: auto;

JSFiddle: https://jsfiddle.net/0x0049/koodkcng/
Pure JS version (IE9+): https://jsfiddle.net/0x0049/koodkcng/1/

This works no matter the height or width of the page or modal dialog, allows scrolling no matter where your mouse/finger is, doesn't have the jarring jump some solutions have that disable scroll on the main content, and looks great too.

I use following code, found somewhere in the internet don't remember the source though.

    var allText;
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function () {
        if (rawFile.readyState === 4) {
            if (rawFile.status === 200 || rawFile.status == 0) {
                allText = rawFile.responseText;
            }
        }
    }
    rawFile.send(null);
    return JSON.parse(allText);

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

You just need to click on console at the bottom of the screen in phpMyAdmin and you will get the Executed history:

Yes, a menu gives you the bar but it doesn't give you any items to put in the bar. You need something like (from one of my own projects):

    <Separator />
    <MenuItem Click="MenuItem_Click">
        <MenuItem.Header>
            <DockPanel>
                <TextBlock>Step</TextBlock>

I had this problem. Couldn't install apk via the Downloads app. However opening the apk in a file manager app allowed me to install it fine. Using OI File Manager on stock Nexus 7 4.2.1

$("#name", '#form2').val("Hello World")

I would like to propose a significantly faster (and memory efficient) alternative: strtok rather than preg_split.

$separator = "\r\n";
$line = strtok($subject, $separator);

while ($line !== false) {
    # do something with $line
    $line = strtok( $separator );
}

Testing the performance, I iterated 100 times over a test file with 17 thousand lines: preg_split took 27.7 seconds, whereas strtok took 1.4 seconds.

Note that though the $separator is defined as "\r\n", strtok will separate on either character - and as of PHP4.1.0, skip empty lines/tokens.

See the strtok manual entry: http://php.net/strtok

You can't use $(this) since jQuery doesn't know what it is there. You seem to be overcomplicating things. You can do $('#content h1.aktiv').hide(). There's no reason to test to see if the class exists.

Update 17/07/27: As this is the most-voted answer, I should update this to include current information locally (with links to the references).

From the spec ^[1]:

The aside element represents a section of a page that consists of content that is tangentially related to the content of the parenting sectioning content, and which could be considered separate from that content. Such sections are often represented as sidebars in printed typography.

Great! Exactly what we're looking for. In addition, it is best to check on <section> as well.

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content. Each section should be identified, typically by including a heading (h1-h6 element) as a child of the section element.

...

A general rule is that the section element is appropriate only if the element’s contents would be listed explicitly in the document’s outline.

Excellent. Just what we're looking for. As opposed to <article> ^[2] which is for "self-contained" content, <section> allows for related content that isn't stand-alone, or generic enough for a <div> element.

As such, the spec seems to suggest that using Option 1, <aside> with <section> children is best practice.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

Are you sure you've connected to the db? (I ask because I don't see a port specified)

try:

mongoose.connection.on("open", function(){
  console.log("mongodb is connected!!");
});

Also, you can do a "show collections" in mongo shell to see the collections within your db - maybe try adding a record via mongoose and see where it ends up?

From the look of your connection string, you should see the record in the "test" db.

Hope it helps!

You should make x and y numpy arrays, not lists:

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
              0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
              0.478,0.335,0.365,0.424,0.390,0.585,0.511])

With this change, it produces the expect plot. If they are lists, m * x will not produce the result you expect, but an empty list. Note that m is anumpy.float64 scalar, not a standard Python float.

I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:

In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]

while multiplying a list with a float gives an error (as I think it should):

In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'

The weird thing is that multiplying a Python list with a Numpy scalar apparently works:

In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []

In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]

In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]

So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:

In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123,  2.123,  3.123])

In this moment with the last version of the C# driver (2.3.0) the only way I found to get the database name specified in connection string is this:

var connectionString = @"mongodb://usr:[email protected],srv2.acme.net,srv3.acme.net/dbName?replicaSet=rset";
var mongoUrl = new MongoUrl(connectionString);
var dbname = mongoUrl.DatabaseName;
var db = new MongoClient(mongoUrl).GetDatabase(dbname);
db.GetCollection<MyType>("myCollectionName");

os.path.abspath(os.path.join(os.path.dirname( __file__ ), '..', 'templates'))

As far as where the templates folder should go, I don't know since Django 1.4 just came out and I haven't looked at it yet. You should probably ask another question on SE to solve that issue.

You can also use normpath to clean up the path, rather than abspath. However, in this situation, Django expects an absolute path rather than a relative path.

For cross platform compatability, use os.pardir instead of '..'.

I just want to write an small enhancement for the answer of amirnissim
The script posted doesn't support IE8, because "event.which" seems to be always empty in IE8.
To solve this problem you just need to additionally check for "event.keyCode":

listener = function (event) {
  if (event.which == 13 || event.keyCode == 13) {
    var suggestion_selected = $(".pac-item.pac-selected").length > 0;
    if(!suggestion_selected){
      var simulated_downarrow = $.Event("keydown", {keyCode:40, which:40})
      orig_listener.apply(input, [simulated_downarrow]);
    }
  }
  orig_listener.apply(input, [event]);
};

the domain was setup wrong so all sessions were ignored because the user cookie was never set right hope this will help someone.

To convert time in millis directly to minutes: second format you can use this

String durationText = DateUtils.formatElapsedTime(timeInMillis / 1000));

This will return a string with time in proper formatting. It worked for me.

In the question, there existed a race condition between:

1. The browser's attempt to initialize the drop-down list, ready to have its selected index updated, and
2. Your code to set the selected index

Your code was consistently winning this race and attempting to set drop-down selection before the browser was ready, meaning that the bug would appear.

This race existed because JavaScript has a single thread of execution that is shared with page rendering. In effect, running JavaScript blocks the updating of the DOM.

Your workaround was:

setTimeout(callback, 0)

Invoking setTimeout with a callback, and zero as the second argument will schedule the callback to be run asynchronously, after the shortest possible delay - which will be around 10ms when the tab has focus and the JavaScript thread of execution is not busy.

The OP's solution, therefore was to delay by about 10ms, the setting of the selected index. This gave the browser an opportunity to initialize the DOM, fixing the bug.

Every version of Internet Explorer exhibited quirky behaviors and this kind of workaround was necessary at times. Alternatively it might have been a genuine bug in the OP's codebase.

For boolean logic, use & and |.

np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,3), columns=list('ABC'))

>>> df
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
2  0.950088 -0.151357 -0.103219
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

>>> df.loc[(df.C > 0.25) | (df.C < -0.25)]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

To see what is happening, you get a column of booleans for each comparison, e.g.

df.C > 0.25
0     True
1    False
2    False
3     True
4     True
Name: C, dtype: bool

When you have multiple criteria, you will get multiple columns returned. This is why the join logic is ambiguous. Using and or or treats each column separately, so you first need to reduce that column to a single boolean value. For example, to see if any value or all values in each of the columns is True.

# Any value in either column is True?
(df.C > 0.25).any() or (df.C < -0.25).any()
True

# All values in either column is True?
(df.C > 0.25).all() or (df.C < -0.25).all()
False

One convoluted way to achieve the same thing is to zip all of these columns together, and perform the appropriate logic.

>>> df[[any([a, b]) for a, b in zip(df.C > 0.25, df.C < -0.25)]]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

My two liners... generally Interviewer wanted the below answer.

Hashing is one way . You can not convert your data/ string from a hash code.

Encryption is 2 way - you can decrypt again the encrypted string if you have the key with you.

JSONArray jsonChildArray = (JSONArray) jsonChildArray.get("LanguageLevels");
    JSONObject secObject = (JSONObject) jsonChildArray.get(1);

I think this should work, but i do not have the possibility to test it at the moment..

You could use Object.keys and then forEach over the returned array of keys:

var myObject = { 'a': 1, 'b': 2, 'c': 3 },
    newObject = {};
Object.keys(myObject).forEach(function (key) {
    var value = myObject[key];
    newObject[key] = value * value;
});

Or in a more modular fashion:

function map(obj, callback) {
    var result = {};
    Object.keys(obj).forEach(function (key) {
        result[key] = callback.call(obj, obj[key], key, obj);
    });
    return result;
}

newObject = map(myObject, function(x) { return x * x; });

Note that Object.keys returns an array containing only the object's own enumerable properties, thus it behaves like a for..in loop with a hasOwnProperty check.

Through Boost you can do it >

std::vector<boost::any> vecobj;
    boost::shared_ptr<string> sharedString1(new string("abcdxyz!"));    
    boost::shared_ptr<int> sharedint1(new int(10));
    vecobj.push_back(sharedString1);
    vecobj.push_back(sharedint1);

> for inserting different object type in your vector container. while for accessing you have to use any_cast, which works like dynamic_cast, hopes it will work for your need.

<body onload="window.print()"> or window.onload = function() { window.print(); }

If you don't want 3D border use:

border:#f00 1px solid;

To have a constant date format irrespective of the computer settings, you must use 3 different input elements to capture day, month, and year respectively. However, you need to validate the user input to ensure that you have a valid date as shown bellow

<input id="txtDay" type="text" placeholder="DD" />

<input id="txtMonth" type="text" placeholder="MM" />

<input id="txtYear" type="text" placeholder="YYYY" />
<button id="but" onclick="validateDate()">Validate</button>


  function validateDate() {
    var date = new Date(document.getElementById("txtYear").value, document.getElementById("txtMonth").value, document.getElementById("txtDay").value);

    if (date == "Invalid Date") {
        alert("jnvalid date");

    }
}

Here is the solution in javascript while loop:

> var i = 0, out = '';
>  while( i <= 4)
>     {
>       out = out + '* ';
>       document.write('<br> '+ out);
>       i++;
>     } 
>  
> document.write('<br>');

This is one of those instances where jquery actually makes it more complicated than what the DOM already provides.

let { top, bottom, height, width, //etc } = $('#bottom')[0].getBoundingClientRect();
return top;

I think the problem is here:

[contains(text()='Some text')]

To break this down,

1. The [] are a conditional that operates on each individual node in that node set -- each span node in your case. It matches if any of the individual nodes it operates on match the conditions inside the brackets.
2. text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.
3. contains is a function that operates on a string. If it is passed a node set, the node set is converted into a string by returning the string-value of the node in the node-set that is first in document order.

You should try to change this to

[text()[contains(.,'Some text')]]

1. The outer [] are a conditional that operates on each individual node in that node set text() is a selector that matches all of the text nodes that are children of the context node -- it returns a node set.

2. The inner [] are a conditional that operates on each node in that node set.

3. contains is a function that operates on a string. Here it is passed an individual text node (.).

You have mentioned Wrong id

alert(document.getElementById("name").value);

if you want to use name attribute then

alert(document.getElementsByName("username")[0].value);

Updates:

input type="text" id="name" name="username"  

id is different from name

I was just playing around with this, too. One way you can add extra weight is in the ORDER BY area of the code.

For example, if you were matching 3 different columns and wanted to more heavily weight certain columns:

SELECT search.*,
MATCH (name) AGAINST ('black' IN BOOLEAN MODE) AS name_match,
MATCH (keywords) AGAINST ('black' IN BOOLEAN MODE) AS keyword_match,
MATCH (description) AGAINST ('black' IN BOOLEAN MODE) AS description_match
FROM search
WHERE MATCH (name, keywords, description) AGAINST ('black' IN BOOLEAN MODE)
ORDER BY (name_match * 3  + keyword_match * 2  + description_match) DESC LIMIT 0,100;

For Mac EI caption/Mac Sierra, Chrome extension folders were located at

/Users/$USER/Library/Application\ Support/Google/Chrome/Profile*/Extensions/

I queried Google for the usage of the different methods on GitHub. This is done by running a Google search query for each method and limiting the query to the github.com domain and the .cs file extension by using the query "site:github.com file:cs ..."

It seems that the First* methods are more commonly used than the Single* methods.

| Method               | Results |
|----------------------|---------|
| FirstAsync           |     315 |
| SingleAsync          |     166 |
| FirstOrDefaultAsync  |     357 |
| SingleOrDefaultAsync |     237 |
| FirstOrDefault       |   17400 |
| SingleOrDefault      |    2950 |

Try this:

Swift 4

myButton.addTarget(self,
                   action: #selector(myAction),
                   for: .touchUpInside)

Objective-C

[myButton addTarget:self 
             action:@selector(myAction) 
   forControlEvents:UIControlEventTouchUpInside];

You can find a rich source of information in Apple's Documentation. Have a look at the UIButton's documentation, it will reveal that UIButton is a descendant of UIControl, which implements the method to add targets.

--

You'll need to pay attention to whether add colon or not after myAction in action:@selector(myAction)

Here's the reference.

We simply did:

import io
from pathlib import Path

    def test_my_upload(self, accept_json):
        """Test my uploads endpoint for POST."""
        data = {
            "filePath[]": "/tmp/bin",
            "manifest[]": (io.StringIO(str(Path(__file__).parent /
                                           "path_to_file/npmlist.json")).read(),
                           'npmlist.json'),
        }
        headers = {
            'a': 'A',
            'b': 'B'
        }
        res = self.client.post(api_route_for('/test'),
                               data=data,
                               content_type='multipart/form-data',
                               headers=headers,
                               )
        assert res.status_code == 200

This has to do with contiguous memory.

Here's some info I found online for somebody asking that before, supposedly from a "VM god":

The reason we need a contiguous memory region for the heap is that we have a bunch of side data structures that are indexed by (scaled) offsets from the start of the heap. For example, we track object reference updates with a "card mark array" that has one byte for each 512 bytes of heap. When we store a reference in the heap we have to mark the corresponding byte in the card mark array. We right shift the destination address of the store and use that to index the card mark array. Fun addressing arithmetic games you can't do in Java that you get to (have to :-) play in C++.

Usually we don't have trouble getting modest contiguous regions (up to about 1.5GB on Windohs, up to about 3.8GB on Solaris. YMMV.). On Windohs, the problem is mostly that there are some libraries that get loaded before the JVM starts up that break up the address space. Using the /3GB switch won't rebase those libraries, so they are still a problem for us.

We know how to make chunked heaps, but there would be some overhead to using them. We have more requests for faster storage management than we do for larger heaps in the 32-bit JVM. If you really want large heaps, switch to the 64-bit JVM. We still need contiguous memory, but it's much easier to get in a 64-bit address space.

Be wary, too, of inheriting workspace settings in your projects for Java Compiler/Compliance settings. I had a project that was imported into Eclipse. Eclipse generated the project with a J2SE 1.4 JRE, compiler, and compliance settings.

When I went in and manually updated these settings and un-checked the "Enable project specific settings" box, I was still receiving build errors relating to 1.5 level compliance (even though the workspace settings were clearly 1.6). It wasn't until I re-checked the "Enable project specific settings" box and manually set the compiler/compliance levels to 1.6 did the errors go away.

When dialing a number within the country you are in, you still need to dial the national trunk number before the rest of the number. For example, in Australia one would dial:

   0 - trunk prefix
   2 - Area code for New South Wales
6555 - STD code for a specific telephone exchange
1234 - Telephone Exchange specific extension.

For a mobile phone this becomes

   0 -      trunk prefix
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

Now, when I want to dial via the international trunk, you need to drop the trunk prefix and replace it with the international dialing prefix

   + -      Short hand for the country trunk number
  61 -      Country code for Australia
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

This is why you often find that the first digit of a telephone number is dropped when dialling internationally, even when using international prefixing to dial within the same country.

So as per the trunk prefix for Germany drop the 0 and add the +49 for Germany's international calling code (for example) giving:

<a href="tel:+496170961709" class="Blondie">_x000D_
    Call me, call me any, anytime_x000D_
      <b>Call me (call me) I'll arrive</b>_x000D_
        When you're ready we can share the wine!_x000D_
</a>

Either set the openssl present in Git as your default openssl and include that into your path in environmental variables (quick way)

OR

1. Install the system-specific openssl from this link.
2. set the following variable : set OPENSSL_CONF=LOCATION_OF_SSL_INSTALL\bin\openssl.cfg
3. Update the path : set Path=...Other Values here...;LOCATION_OF_SSL_INSTALL\bin

You can't really do this without some form of scripting to the best of my knowledge.

<form id="my_form">
<!-- Your Form -->    
<a href="javascript:{}" onclick="document.getElementById('my_form').submit(); return false;">submit</a>
</form>

Example from Here.

I believe the best solution will be using head()

Considering your example:

+---+---+
|  A|  B|
+---+---+
|1.0|4.0|
|2.0|5.0|
|3.0|6.0|
+---+---+

Using agg and max method of python we can get the value as following :

from pyspark.sql.functions import max df.agg(max(df.A)).head()[0]

This will return: 3.0

Make sure you have the correct import:
from pyspark.sql.functions import max The max function we use here is the pySPark sql library function, not the default max function of python.

You should use

=COUNTIF(A2:A51, "*iPad*")/COUNTA(A2:A51)

Additionally, if you wanted to count more than one element, like iPads OR Kindles, you would use

=SUM(COUNTIF(A2:A51, {"*iPad*", "*kindle*"}))/COUNTA(A2:A51)

in the numerator.

Found a solution.

1) Go to where your SDK is located that android studio/eclipse is using. If you are using Android studio, go to extras\android\m2repository\com\android\support\. If you are using eclipse, go to \extras\android\support\

2) See what folders you have, for me I had gridlayout-v7, support-v4 and support-v13.

3) click into support-v4 and see what number the following folder is, mine was named 13.0

Since you are using "com.android.support:support-v4:18.0.+", change this to reflect what version you have, for example I have support-v4 so first part v4 stays the same. Since the next path is 13.0, change your 18.0 to:

"com.android.support:support-v4:13.0.+"

This worked for me, hope it helps!

Update:

I noticed I had android studio set up with the wrong SDK which is why originally had difficulty updating! The path should be C:\Users\Username\AppData\Local\Android\android-sdk\extras\

Also note, if your SDK is up to date, the code will be:

"com.android.support:support-v4:19.0.+"

you have to place double-backslash

$str = str_replace('\\', '/', $str);

According to the docs, router.push seems like the preferred method:

To navigate to a different URL, use router.push. This method pushes a new entry into the history stack, so when the user clicks the browser back button they will be taken to the previous URL.

source: https://router.vuejs.org/en/essentials/navigation.html

FYI : Webpack & component setup, single page app (where you import the router through Main.js), I had to call the router functions by saying:

this.$router

Example: if you wanted to redirect to a route called "Home" after a condition is met:

this.$router.push('Home') 

Just adding to the above answer, In a web application @valid is used where the bean to be validated is also annotated with validation annotations e.g. @NotNull, @Email(hibernate annotation) so when while getting input from user the values can be validated and binding result will have the validation results. bindingResult.hasErrors() will tell if any validation failed.

var Browser = new function () {
    var self = this;
    var nav = navigator.userAgent.toLowerCase();
    if (nav.indexOf('msie') != -1) {
        self.ie = {
            version: toFloat(nav.split('msie')[1])
        };
    };
};


if(Browser.ie && Browser.ie.version > 9)
{
    // do something
}

The Groovy way to do this is

def list = []
list << new MyType(...)

which creates a list and uses the overloaded leftShift operator to append an item

See the Groovy docs on Lists for lots of examples.

A similar question is: Mapping a NumPy array in place. If you can find a ufunc for your f(), then you should use the out parameter.

It's possible to see output intended for console by using command line redirection.

For example:

C:\src\bin\Debug\Example.exe > output.txt

will write all the content to output.txt file.

When you make the input, set it to be readonly.

<input type="text" name="datepicker" id="datepicker" readonly="readonly" />

 foreach (string file in System.IO.Directory.GetFiles(path))
 {
    System.IO.File.Delete(file);
 }

 foreach (string subDirectory in System.IO.Directory.GetDirectories(path))
 {
     System.IO.Directory.Delete(subDirectory,true); 
 } 

Unfortunately typescript does not support multiple inheritance. Therefore there is no completely trivial answer, you will probably have to restructure your program

Here are a few suggestions:

• If this additional class contains behaviour that many of your subclasses share, it makes sense to insert it into the class hierarchy, somewhere at the top. Maybe you could derive the common superclass of Sprite, Texture, Layer, ... from this class ? This would be a good choice, if you can find a good spot in the type hirarchy. But I would not recommend to just insert this class at a random point. Inheritance expresses an "Is a - relationship" e.g. a dog is an animal, a texture is an instance of this class. You would have to ask yourself, if this really models the relationship between the objects in your code. A logical inheritance tree is very valuable

• If the additional class does not fit logically into the type hierarchy, you could use aggregation. That means that you add an instance variable of the type of this class to a common superclass of Sprite, Texture, Layer, ... Then you can access the variable with its getter/setter in all subclasses. This models a "Has a - relationship".

• You could also convert your class into an interface. Then you could extend the interface with all your classes but would have to implement the methods correctly in each class. This means some code redundancy but in this case not much.

You have to decide for yourself which approach you like best. Personally I would recommend to convert the class to an interface.

One tip: Typescript offers properties, which are syntactic sugar for getters and setters. You might want to take a look at this: http://blogs.microsoft.co.il/gilf/2013/01/22/creating-properties-in-typescript/

Change

JSONObject objects = getArray.getJSONArray(i);

to

JSONObject objects = getArray.getJSONObject(i);

or to

JSONObject objects = getArray.optJSONObject(i);

depending on which JSON-to/from-Java library you're using. (It looks like getJSONObject will work for you.)

Then, to access the string elements in the "objects" JSONObject, get them out by element name.

String a = objects.get("A");

If you need the names of the elements in the JSONObject, you can use the static utility method JSONObject.getNames(JSONObject) to do so.

String[] elementNames = JSONObject.getNames(objects);

"Get the value for the first element and the value for the last element."

If "element" is referring to the component in the array, note that the first component is at index 0, and the last component is at index getArray.length() - 1.

I want to iterate though the objects in the array and get thier component and thier value. In my example the first object has 3 components, the scond has 5 and the third has 4 components. I want iterate though each of them and get thier component name and value.

The following code does exactly that.

import org.json.JSONArray;
import org.json.JSONObject;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    String jsonInput = "{\"JObjects\":{\"JArray1\":[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\"},{\"A\":\"a1\",\"B\":\"b2\",\"C\":\"c3\",\"D\":\"d4\",\"E\":\"e5\"},{\"A\":\"aa\",\"B\":\"bb\",\"C\":\"cc\",\"D\":\"dd\"}]}}";

    // "I want to iterate though the objects in the array..."
    JSONObject outerObject = new JSONObject(jsonInput);
    JSONObject innerObject = outerObject.getJSONObject("JObjects");
    JSONArray jsonArray = innerObject.getJSONArray("JArray1");
    for (int i = 0, size = jsonArray.length(); i < size; i++)
    {
      JSONObject objectInArray = jsonArray.getJSONObject(i);

      // "...and get thier component and thier value."
      String[] elementNames = JSONObject.getNames(objectInArray);
      System.out.printf("%d ELEMENTS IN CURRENT OBJECT:\n", elementNames.length);
      for (String elementName : elementNames)
      {
        String value = objectInArray.getString(elementName);
        System.out.printf("name=%s, value=%s\n", elementName, value);
      }
      System.out.println();
    }
  }
}
/*
OUTPUT:
3 ELEMENTS IN CURRENT OBJECT:
name=A, value=a
name=B, value=b
name=C, value=c

5 ELEMENTS IN CURRENT OBJECT:
name=D, value=d4
name=E, value=e5
name=A, value=a1
name=B, value=b2
name=C, value=c3

4 ELEMENTS IN CURRENT OBJECT:
name=D, value=dd
name=A, value=aa
name=B, value=bb
name=C, value=cc
*/

try this code to format as used in Brazil:

    DecimalFormat df = new DecimalFormat(
      "#,##0.00", 
      new DecimalFormatSymbols(new Locale("pt", "BR")));

    BigDecimal value = new BigDecimal(123456.00);

    System.out.println(df.format(value.floatValue()));

    // results: "123.456,00"

In my case I need to clear just the view and restart the controller. I could get my intention with this snippet:

$ionicHistory.clearCache([$state.current.name]).then(function() {
  $state.reload();
}

The cache still working and seems that just the view is cleared.

ionic --version says 1.7.5.

$("body").stop().animate({
        scrollTop: 0
    }, 500, 'swing', function () {
        console.log(confirm('Like This'))
    }
);

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

this should do:

//Main Class
public class SomeClass {

    //Sub-Class
    public static class AnotherClass {
        public enum MyEnum {
            VALUE_A, VALUE_B
        }    
        public MyEnum myEnum;
    }

    public void someMethod() { 
        AnotherClass.MyEnum enumExample = AnotherClass.MyEnum.VALUE_A; //...

        switch (enumExample) {
            case VALUE_A: { //<-- error on this line
            //..
            break;
            }
        }
    }
}

Try to add the following settings to web.config file.

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

git log -n 1 [branch_name]

branch_name (may be remote or local branch) is optional. Without branch_name, it will show the latest commit on the current branch.

For example:

git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch

git log -n 1 --pretty=format:"%H"  #To get only hash value of commit

One alternative is to represent your 2D array as a 1D array. This can make element-wise operations more efficient. You should probably wrap it in a class that would also contain width and height.

Another alternative is to represent a 2D array as an std::vector<std::vector<int> >. This will let you use STL's algorithms for array arithmetic, and the vector will also take care of memory management for you.

I was facing the same issue.
Commonly This kind of error occurs due to client has closed its connection and server still trying to write on that client.
So make sure that your client has its connection open until server done with its outputstream.
And one more thing, Don`t forgot to close input and output stream.

Hope this helps.
And if still facing issue than brief your problem here in details.

You can functionalize this however you like.

Simply check it by calling post method on your layout or view

 view.post( new Runnable() {
     @Override
     public void run() {
        // your layout is now drawn completely , use it here.
      }
});

Long l = 100;
int i = Math.round(l);

I wrote a Collector which, unlike the default java one, does not crash when you have null values:

public static <T, K, U>
        Collector<T, ?, Map<K, U>> toMap(Function<? super T, ? extends K> keyMapper,
                Function<? super T, ? extends U> valueMapper) {
    return Collectors.collectingAndThen(
            Collectors.toList(),
            list -> {
                Map<K, U> result = new HashMap<>();
                for (T item : list) {
                    K key = keyMapper.apply(item);
                    if (result.putIfAbsent(key, valueMapper.apply(item)) != null) {
                        throw new IllegalStateException(String.format("Duplicate key %s", key));
                    }
                }
                return result;
            });
}

Just replace your Collectors.toMap() call to a call to this function and it'll fix the problem.

On Windows you can use the following command.

start javaw -jar JarFile.jar

By doing so, the Command Prompt Window doesn't stay open.

Rails has an except/except! method that returns the hash with those keys removed. If you're already using Rails, there's no sense in creating your own version of this.

class Hash
  # Returns a hash that includes everything but the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false, c: nil}
  #
  # This is useful for limiting a set of parameters to everything but a few known toggles:
  #   @person.update(params[:person].except(:admin))
  def except(*keys)
    dup.except!(*keys)
  end

  # Replaces the hash without the given keys.
  #   hash = { a: true, b: false, c: nil}
  #   hash.except!(:c) # => { a: true, b: false}
  #   hash # => { a: true, b: false }
  def except!(*keys)
    keys.each { |key| delete(key) }
    self
  end
end

Assuming the thread code is out of your control:

From the Java documentation mentioned above:

What if a thread doesn't respond to Thread.interrupt?

In some cases, you can use application specific tricks. For example, if a thread is waiting on a known socket, you can close the socket to cause the thread to return immediately. Unfortunately, there really isn't any technique that works in general. It should be noted that in all situations where a waiting thread doesn't respond to Thread.interrupt, it wouldn't respond to Thread.stop either. Such cases include deliberate denial-of-service attacks, and I/O operations for which thread.stop and thread.interrupt do not work properly.

Bottom Line:

Make sure all threads can be interrupted, or else you need specific knowledge of the thread - like having a flag to set. Maybe you can require that the task be given to you along with the code needed to stop it - define an interface with a stop() method. You can also warn when you failed to stop a task.

If you are testing for file existence you want -e not -L. -L tests for a symlink.

If you like to keep things simple, then here is my solution.

It works for any number of integers taken from standard input. It also works for negative integers. Enter end when you are done.

#include <iostream>

int main()
{
int max,min,input;
std::cout<<"Enter the number: ";
std::cin>>input;
min=max=input;

while(std::cin>>input){
    if(input>max) max=input;
    if(input<min) min=input;
    std::cout<<"Enter the number: ";
}
std::cout<<"\nMax: "<<max<<"\nMin: "<<min;
}

For regular Windows users who are not skilled with computers, it is practically not possible to install and use extensions from outside the Chrome Web Store.

Users of other operating systems (Linux, Mac, Chrome OS) can easily install unpacked extensions (in developer mode).
Windows users can also load an unpacked extension, but they will always see an information bubble with "Disable developer mode extensions" when they start Chrome or open a new incognito window, which is really annoying. The only way for Windows users to use unpacked extensions without such dialogs is to switch to Chrome on the developer channel, by installing https://www.google.com/chrome/browser/index.html?extra=devchannel#eula.

Extensions can be loaded in unpacked mode by following the following steps:

1. Visit chrome://extensions (via omnibox or menu -> Tools -> Extensions).
2. Enable Developer mode by ticking the checkbox in the upper-right corner.
3. Click on the "Load unpacked extension..." button.
4. Select the directory containing your unpacked extension.

If you have a crx file, then it needs to be extracted first. CRX files are zip files with a different header. Any capable zip program should be able to open it. If you don't have such a program, I recommend 7-zip.

These steps will work for almost every extension, except extensions that rely on their extension ID. If you use the previous method, you will get an extension with a random extension ID. If it is important to preserve the extension ID, then you need to know the public key of your CRX file and insert this in your manifest.json. I have previously given a detailed explanation on how to get and use this key at https://stackoverflow.com/a/21500707.

The last argument of CONVERT seems to determine the format used for parsing. Consult MSDN docs for CONVERT.

111 - the one you are using is Japan yy/mm/dd.

I guess the one you are looking for is 103, that is dd/mm/yyyy.

So you should try:

 SELECT convert(datetime, '23/07/2009', 103)

I had the same problem. I'm using this solution I found: React Native display SVG from a file

It's not perfect, and i'm revisiting today, because it performs a lot worse on Android.

IN completion to above answers, you can also customize your fallbacks for each async call you do, so that each call to the generic ASYNC method will populate different data, depending on the onTaskDone stuff you put there.

  Main.FragmentCallback FC= new  Main.FragmentCallback(){
            @Override
            public void onTaskDone(String results) {

                localText.setText(results); //example TextView
            }
        };

new API_CALL(this.getApplicationContext(), "GET",FC).execute("&Books=" + Main.Books + "&args=" + profile_id);

Remind: I used interface on the main activity thats where "Main" comes, like this:

public interface FragmentCallback {
    public void onTaskDone(String results);


}

My API post execute looks like this:

  @Override
    protected void onPostExecute(String results) {

        Log.i("TASK Result", results);
        mFragmentCallback.onTaskDone(results);

    }

The API constructor looks like this:

 class  API_CALL extends AsyncTask<String,Void,String>  {

    private Main.FragmentCallback mFragmentCallback;
    private Context act;
    private String method;


    public API_CALL(Context ctx, String api_method,Main.FragmentCallback fragmentCallback) {
        act=ctx;
        method=api_method;
        mFragmentCallback = fragmentCallback;


    }

You can access the index attribute of a df using df.index[i]

Sounds like you might want a light box,and since you didnt tag your question with jQuery included is a pure JS example of how to make one.

JS

var opener = document.getElementById("opener");

opener.onclick = function(){

    var lightbox = document.getElementById("lightbox"),
        dimmer = document.createElement("div");

    dimmer.style.width =  window.innerWidth + 'px';
    dimmer.style.height = window.innerHeight + 'px';
    dimmer.className = 'dimmer';

    dimmer.onclick = function(){
        document.body.removeChild(this);   
        lightbox.style.visibility = 'hidden';
    }

    document.body.appendChild(dimmer);

    lightbox.style.visibility = 'visible';
    lightbox.style.top = window.innerHeight/2 - 50 + 'px';
    lightbox.style.left = window.innerWidth/2 - 100 + 'px';
    return false;
}

Markup

<div id="lightbox">Testing out the lightbox</div>
<a href="#" id="opener">Click me</a>

CSS

#lightbox{
    visibility:hidden;
    position:absolute;
    background:red;
    border:2px solid #3c3c3c;
    color:white;
    z-index:100;
    width: 200px;
    height:100px;
    padding:20px;
}

.dimmer{
    background: #000;
    position: absolute;
    opacity: .5;
    top: 0;
    z-index:99;
}

I just do a remake of RobG solution

var daysInMonth = [31,28,31,30,31,30,31,31,30,31,30,31];
var isLeap = new Date(theYear,1,29).getDate() == 29;

if (isLeap) {
  daysInMonth[1] = 29;
}
return theDay <= daysInMonth[--theMonth]

I ran into this because I made a copy-and-paste of ngBoilerplate into my project on a Mac without Finder showing hidden files. So .bower was not copied with the rest of ngBoilerplate. Thus bower moved resources to bower_components (defult) instead of vendor (as configured) and my app didn't get angular. Probably a corner case, but it might help someone here.

Setting windowLightStatusBar to true not works with Mi phones, some Meizu phones, Blackview phones, WileyFox etc. I've found such hack for Mi and Meizu devices. This is not a comprehensive solution of this perfomance problem, but maybe it would be useful to somebody.

And I think, it would be better to tell your customer that coloring status bar (for example) white - is not a good idea. instead of using different hacks it would be better to define appropriate colorPrimaryDark according to the guidelines

It depends in the context. Another scenario which wasn't yet covered is the following. Let's say you have one file with a class with a specific method in it

class Scraper:
    def __init__(self):
        pass

    def scrape_html(self, html: str):
        pass

and in the bottom of the file you have something like

if __name__ == "__main__":
    # some
    # commands
    # doing
    # stuff

making it the whole file look like this

class Scraper:
    def __init__(self):
        pass

    def scrape_html(self, html: str):
        pass

if __name__ == "__main__":
    # some
    # commands
    # doing
    # stuff

If in scrape_html() you open up, for example, an if/else statement

class Scraper:
    def __init__(self):
        pass

    def scrape_html(self, html: str):
        if condition:
            pass
        else:

if __name__ == "__main__":
    parser = argparse.ArgumentParser()

You'll need to add pass or whatever you want to to that else statement or else you'll get

Expected indented block

Unindent not expected

Expected expression

and in the first row

Unexpected indentation

Adding that pass would fix all of these four problems.

Could this be a typo? (two Ps in ppasscode, intended?)

$_POST['ppasscode'];

I would make sure and do:

print_r($_POST);

and make sure the data is accurate there, and then echo out what it should look like:

echo hash('sha256', $_POST['ppasscode']);

Compare this output to what you have in the database (manually). By doing this you're exploring your possible points of failure:

1. Getting password from form
2. hashing the password
3. stored password
4. comparison of the two.

this might help someone who had similar issue like me , i followed all naming and interface standards., But i was still facing issue.

My param name was -->  update_datetime 

I wanted to fetch my entities based on the update_datetime in the descending order, and i was getting the error

org.springframework.data.mapping.PropertyReferenceException: No property update found for type Release!

Somehow it was not reading the Underscore character --> ( _ )

so for workaround i changed the property name as  --> updateDatetime 

and then used the same for using JpaRepository methods.

It Worked !

The Differences in as easy as much possible: After having a basic understanding, the other comments posted above will be easier to catch.

Shell - "Shell" is a program, which facilitates the interaction between the user and the operating system (kernel). There are many shell implementation available, like sh, bash, csh, zsh...etc.

Using any of the Shell programs, we will be able to execute commands that are supported by that shell program.

Bash - It derived from Bourne-again Shell. Using this program, we will be able to execute all the commands specified by Shell. Also, we will be able to execute some commands that are specifically added to this program. Bash has backward compatibility with sh.

Sh - It derived from Bourne Shell. "sh" supports all the commands specified in the shell. Means, Using this program, we will be able to execute all the commands specified by Shell.

You can use this function to convert comma-delimited single character strings to list-

def stringtolist(x):
    mylist=[]
    for i in range(0,len(x),2):
        mylist.append(x[i])
    return mylist

On Windows, Chrome might be installed in your AppData folder:

"C:\Users\\AppData\Local\Google\Chrome\Application"

Before you execute the command, make sure all of your Chrome windows are closed and not otherwise running. Or, the command line param would not be effective.

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

The Java Native Access library is typically used for calling native shared libraries from Java. Within this library there exist methods for determining the size of Java objects:

The getNativeSize(Class cls) method and its overloads will provide the size for most classes.

Alternatively, if your classes inherit from JNA's Structure class the calculateSize(boolean force) method will be available.

For instance you can use

update tablename set datetimefield='19980223 14:23:05'
update tablename set datetimefield='02/23/1998 14:23:05'
update tablename set datetimefield='1998-12-23 14:23:05'
update tablename set datetimefield='23 February 1998 14:23:05'
update tablename set datetimefield='1998-02-23T14:23:05'

You need to be careful of day/month order since this will be language dependent when the year is not specified first. If you specify the year first then there is no problem; date order will always be year-month-day.

I've managed to bind a custom model to an element at runtime. The code is here: http://jsfiddle.net/ZiglioNZ/tzD4T/457/

The interesting bit is that I apply the data-bind attribute to an element I didn't define:

    var handle = slider.slider().find(".ui-slider-handle").first();
    $(handle).attr("data-bind", "tooltip: viewModel.value");
    ko.applyBindings(viewModel.value, $(handle)[0]);

I think fontsize: command in YAML only works for LaTeX / pdf. Apart, in standard latex classes (article, book, and report) only three font sizes are accepted (10pt, 11pt, and 12pt).

Regarding appearance (different font types and colors), you can specify a theme:. See Appearance and Style.

I guess, what you are looking for is your own css. Make a file called style.css, save it in the same folder as your .Rmd and include it in the YAML header:

---
output:
  html_document:
    css: style.css
---

In the css-file you define your font-type and size:

/* Whole document: */
body{
  font-family: Helvetica;
  font-size: 16pt;
}
/* Headers */
h1,h2,h3,h4,h5,h6{
  font-size: 24pt;
}

Take a look at the library I wrote: https://github.com/tachyons-css/react-native-style-tachyons

It allows you to specify a root-fontSize (rem) upon start, which you can make dependent of your PixelRatio or other device-characteristics.

Then you get styles relative to your rem, not only fontSize, but paddings etc. as well:

<Text style={[s.f5, s.pa2, s.tc]}>
     Something
</Text>

Expanation:

• f5is always your base-fontsize
• pa2 gives you padding relative to your base-fontsize.

And it's maybe also handy to know that BigTable is not a relational database (like MySQL) but a huge (distributed) hash table which has very different characteristics. You can play around with (a limited version) of BigTable yourself on the Google AppEngine platform.

Next to Hadoop mentioned above there are many other implementations that try to solve the same problems as BigTable (scalability, availability). I saw a nice blog post yesterday listing most of them here.

For maximum flexibility, I usually prefer working with SizedBox like this:

Row(
                                children: <Widget>[
                                  SizedBox(
                                      width: 235,
                                      child: Text('Hey, ')),
                                  SizedBox(
                                      width: 110,
                                      child: Text('how are'),
                                  SizedBox(
                                      width: 10,
                                      child: Text('you?'))
                                ],
                              )

I've experienced problems with text alignment when using alignment in the past, whereas sizedbox always does the work.

simplify2array is a base function that is fairly intuitive. However, since R's default is to fill in data by columns first, you will need to transpose the output. (sapply uses simplify2array, as documented in help(sapply).)

> t(simplify2array(a))
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

A dictionary probably isn't what you should be using in this case. A more full featured library would be a better alternative. Probably a real database. The easiest would be sqlite. You can keep the whole thing in memory by passing in the string ':memory:' instead of a filename.

If you do want to continue down this path, you can do it with the extra attributes in the key or the value. However a dictionary can't be the key to a another dictionary, but a tuple can. The docs explain what's allowable. It must be an immutable object, which includes strings, numbers and tuples that contain only strings and numbers (and more tuples containing only those types recursively...).

You could do your first example with d = {('apple', 'red') : 4}, but it'll be very hard to query for what you want. You'd need to do something like this:

#find all apples
apples = [d[key] for key in d.keys() if key[0] == 'apple']

#find all red items
red = [d[key] for key in d.keys() if key[1] == 'red']

#the red apple
redapples = d[('apple', 'red')]

Probably a duplicate of this post: A customized input text box in html/html5

input {_x000D_
  border: 0;_x000D_
  outline: 0;_x000D_
  background: transparent;_x000D_
  border-bottom: 1px solid black;_x000D_
}

Have some logic to check the color or have some flag,

function abc() {
    var currentColor = document.getElementById("test").style.color;

    if(currentColor == 'red'){
    document.getElementById("test").style.color="black";
    }else{
   document.getElementById("test").style.color="red";

    }
}
