The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

maybe this will help you out:

if you have null value then in doing mathematical operation you will get this error to resolve it use df[~df['x'].isnull()]df[['x']].astype(int) if you want your dataset to be unchangeable.

Recommend using an npm package such as https://github.com/davetemplin/async-file, as compared to custom functions. For example:

import * as fs from 'async-file';

await fs.rename('/tmp/hello', '/tmp/world');
await fs.appendFile('message.txt', 'data to append');
await fs.access('/etc/passd', fs.constants.R_OK | fs.constants.W_OK);

var stats = await fs.stat('/tmp/hello', '/tmp/world');

TL;DR

Just returning response()->json($promotion) won't solve the issue in this question. $promotion is an Eloquent object, which Laravel will automatically json_encode for the response. The json encoding is failing because of the img property, which is a PHP stream resource, and cannot be encoded.

Details

Whatever you return from your controller, Laravel is going to attempt to convert to a string. When you return an object, the object's __toString() magic method will be invoked to make the conversion.

Therefore, when you just return $promotion from your controller action, Laravel is going to call __toString() on it to convert it to a string to display.

On the Model, __toString() calls toJson(), which returns the result of json_encode. Therefore, json_encode is returning false, meaning it is running into an error.

Your dd shows that your img attribute is a stream resource. json_encode cannot encode a resource, so this is probably causing the failure. You should add your img attribute to the $hidden property to remove it from the json_encode.

class Promotion extends Model
{
    protected $hidden = ['img'];

    // rest of class
}

If you're using typing (introduced in Python 3.5) you can use typing.Optional, where Optional[X] is equivalent to Union[X, None]. It is used to signal that the explicit value of None is allowed . From typing.Optional:

def foo(arg: Optional[int] = None) -> None:
    ...

Deletes all child fields in the database then we use on_delete as so:

class user(models.Model):
 commodities = models.ForeignKey(commodity, on_delete=models.CASCADE)

This worked for me.

   `sudo apt-get install libjpeg-dev`

From the documentation

class typing.Union

Union type; Union[X, Y] means either X or Y.

Hence the proper way to represent more than one return data type is

from typing import Union


def foo(client_id: str) -> Union[list,bool]

But do note that typing is not enforced. Python continues to remain a dynamically-typed language. The annotation syntax has been developed to help during the development of the code prior to being released into production. As PEP 484 states, "no type checking happens at runtime."

>>> def foo(a:str) -> list:
...     return("Works")
... 
>>> foo(1)
'Works'

As you can see I am passing a int value and returning a str. However the __annotations__ will be set to the respective values.

>>> foo.__annotations__ 
{'return': <class 'list'>, 'a': <class 'str'>}

Please Go through PEP 483 for more about Type hints. Also see What are Type hints in Python 3.5?

Kindly note that this is available only for Python 3.5 and upwards. This is mentioned clearly in PEP 484.

I would suggest reading PEP 483 and PEP 484 and watching this presentation by Guido on type hinting.

In a nutshell: Type hinting is literally what the words mean. You hint the type of the object(s) you're using.

Due to the dynamic nature of Python, inferring or checking the type of an object being used is especially hard. This fact makes it hard for developers to understand what exactly is going on in code they haven't written and, most importantly, for type checking tools found in many IDEs (PyCharm and PyDev come to mind) that are limited due to the fact that they don't have any indicator of what type the objects are. As a result they resort to trying to infer the type with (as mentioned in the presentation) around 50% success rate.

To take two important slides from the type hinting presentation:

Why type hints?

1. Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you're passing an object with a type that isn't expected.
2. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors.
3. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren't defined for an object.

Why use static type checkers?

• Find bugs sooner: This is self-evident, I believe.
• The larger your project the more you need it: Again, makes sense. Static languages offer a robustness and control that dynamic languages lack. The bigger and more complex your application becomes the more control and predictability (from a behavioral aspect) you require.
• Large teams are already running static analysis: I'm guessing this verifies the first two points.

As a closing note for this small introduction: This is an optional feature and, from what I understand, it has been introduced in order to reap some of the benefits of static typing.

You generally do not need to worry about it and definitely don't need to use it (especially in cases where you use Python as an auxiliary scripting language). It should be helpful when developing large projects as it offers much needed robustness, control and additional debugging capabilities.

Type hinting with mypy:

In order to make this answer more complete, I think a little demonstration would be suitable. I'll be using mypy, the library which inspired Type Hints as they are presented in the PEP. This is mainly written for anybody bumping into this question and wondering where to begin.

Before I do that let me reiterate the following: PEP 484 doesn't enforce anything; it is simply setting a direction for function annotations and proposing guidelines for how type checking can/should be performed. You can annotate your functions and hint as many things as you want; your scripts will still run regardless of the presence of annotations because Python itself doesn't use them.

Anyways, as noted in the PEP, hinting types should generally take three forms:

• Function annotations (PEP 3107).
• Stub files for built-in/user modules.
• Special # type: type comments that complement the first two forms. (See: What are variable annotations? for a Python 3.6 update for # type: type comments)

Additionally, you'll want to use type hints in conjunction with the new typing module introduced in Py3.5. In it, many (additional) ABCs (abstract base classes) are defined along with helper functions and decorators for use in static checking. Most ABCs in collections.abc are included, but in a generic form in order to allow subscription (by defining a __getitem__() method).

For anyone interested in a more in-depth explanation of these, the mypy documentation is written very nicely and has a lot of code samples demonstrating/describing the functionality of their checker; it is definitely worth a read.

Function annotations and special comments:

First, it's interesting to observe some of the behavior we can get when using special comments. Special # type: type comments can be added during variable assignments to indicate the type of an object if one cannot be directly inferred. Simple assignments are generally easily inferred but others, like lists (with regard to their contents), cannot.

Note: If we want to use any derivative of containers and need to specify the contents for that container we must use the generic types from the typing module. These support indexing.

# Generic List, supports indexing.
from typing import List

# In this case, the type is easily inferred as type: int.
i = 0

# Even though the type can be inferred as of type list
# there is no way to know the contents of this list.
# By using type: List[str] we indicate we want to use a list of strings.
a = []  # type: List[str]

# Appending an int to our list
# is statically not correct.
a.append(i)

# Appending a string is fine.
a.append("i")

print(a)  # [0, 'i']

If we add these commands to a file and execute them with our interpreter, everything works just fine and print(a) just prints the contents of list a. The # type comments have been discarded, treated as plain comments which have no additional semantic meaning.

By running this with mypy, on the other hand, we get the following response:

(Python3)jimmi@jim: mypy typeHintsCode.py
typesInline.py:14: error: Argument 1 to "append" of "list" has incompatible type "int"; expected "str"

Indicating that a list of str objects cannot contain an int, which, statically speaking, is sound. This can be fixed by either abiding to the type of a and only appending str objects or by changing the type of the contents of a to indicate that any value is acceptable (Intuitively performed with List[Any] after Any has been imported from typing).

Function annotations are added in the form param_name : type after each parameter in your function signature and a return type is specified using the -> type notation before the ending function colon; all annotations are stored in the __annotations__ attribute for that function in a handy dictionary form. Using a trivial example (which doesn't require extra types from the typing module):

def annotated(x: int, y: str) -> bool:
    return x < y

The annotated.__annotations__ attribute now has the following values:

{'y': <class 'str'>, 'return': <class 'bool'>, 'x': <class 'int'>}

If we're a complete newbie, or we are familiar with Python 2.7 concepts and are consequently unaware of the TypeError lurking in the comparison of annotated, we can perform another static check, catch the error and save us some trouble:

(Python3)jimmi@jim: mypy typeHintsCode.py
typeFunction.py: note: In function "annotated":
typeFunction.py:2: error: Unsupported operand types for > ("str" and "int")

Among other things, calling the function with invalid arguments will also get caught:

annotated(20, 20)

# mypy complains:
typeHintsCode.py:4: error: Argument 2 to "annotated" has incompatible type "int"; expected "str"

These can be extended to basically any use case and the errors caught extend further than basic calls and operations. The types you can check for are really flexible and I have merely given a small sneak peak of its potential. A look in the typing module, the PEPs or the mypy documentation will give you a more comprehensive idea of the capabilities offered.

Stub files:

Stub files can be used in two different non mutually exclusive cases:

• You need to type check a module for which you do not want to directly alter the function signatures
• You want to write modules and have type-checking but additionally want to separate annotations from content.

What stub files (with an extension of .pyi) are is an annotated interface of the module you are making/want to use. They contain the signatures of the functions you want to type-check with the body of the functions discarded. To get a feel of this, given a set of three random functions in a module named randfunc.py:

def message(s):
    print(s)

def alterContents(myIterable):
    return [i for i in myIterable if i % 2 == 0]

def combine(messageFunc, itFunc):
    messageFunc("Printing the Iterable")
    a = alterContents(range(1, 20))
    return set(a)

We can create a stub file randfunc.pyi, in which we can place some restrictions if we wish to do so. The downside is that somebody viewing the source without the stub won't really get that annotation assistance when trying to understand what is supposed to be passed where.

Anyway, the structure of a stub file is pretty simplistic: Add all function definitions with empty bodies (pass filled) and supply the annotations based on your requirements. Here, let's assume we only want to work with int types for our Containers.

# Stub for randfucn.py
from typing import Iterable, List, Set, Callable

def message(s: str) -> None: pass

def alterContents(myIterable: Iterable[int])-> List[int]: pass

def combine(
    messageFunc: Callable[[str], Any],
    itFunc: Callable[[Iterable[int]], List[int]]
)-> Set[int]: pass

The combine function gives an indication of why you might want to use annotations in a different file, they some times clutter up the code and reduce readability (big no-no for Python). You could of course use type aliases but that sometime confuses more than it helps (so use them wisely).

This should get you familiarized with the basic concepts of type hints in Python. Even though the type checker used has been mypy you should gradually start to see more of them pop-up, some internally in IDEs (PyCharm,) and others as standard Python modules.

I'll try and add additional checkers/related packages in the following list when and if I find them (or if suggested).

Checkers I know of:

• Mypy: as described here.
• PyType: By Google, uses different notation from what I gather, probably worth a look.

Related Packages/Projects:

• typeshed: Official Python repository housing an assortment of stub files for the standard library.

The typeshed project is actually one of the best places you can look to see how type hinting might be used in a project of your own. Let's take as an example the __init__ dunders of the Counter class in the corresponding .pyi file:

class Counter(Dict[_T, int], Generic[_T]):
        @overload
        def __init__(self) -> None: ...
        @overload
        def __init__(self, Mapping: Mapping[_T, int]) -> None: ...
        @overload
        def __init__(self, iterable: Iterable[_T]) -> None: ...

Where _T = TypeVar('_T') is used to define generic classes. For the Counter class we can see that it can either take no arguments in its initializer, get a single Mapping from any type to an int or take an Iterable of any type.

Notice: One thing I forgot to mention was that the typing module has been introduced on a provisional basis. From PEP 411:

A provisional package may have its API modified prior to "graduating" into a "stable" state. On one hand, this state provides the package with the benefits of being formally part of the Python distribution. On the other hand, the core development team explicitly states that no promises are made with regards to the the stability of the package's API, which may change for the next release. While it is considered an unlikely outcome, such packages may even be removed from the standard library without a deprecation period if the concerns regarding their API or maintenance prove well-founded.

So take things here with a pinch of salt; I'm doubtful it will be removed or altered in significant ways, but one can never know.

^** Another topic altogether, but valid in the scope of type-hints: PEP 526: Syntax for Variable Annotations is an effort to replace # type comments by introducing new syntax which allows users to annotate the type of variables in simple varname: type statements.

See What are variable annotations?, as previously mentioned, for a small introduction to these.

You could try as well:

let diceRoll = Int(arc4random_uniform(UInt32(6)))

I had to add "UInt32" to make it work.

Using test

if test ! -z "$(docker images -q <name:tag>)"; then
  echo "Exist"
fi

or in one line

test ! -z "$(docker images -q <name:tag>)" &&  echo exist

I've seen this error when you have a circular dependency.

class A extends B {}
class B extends C {}
class C extends A {}

You can also pipe commands inside Docker container, bash -c "<command1> | <command2>" for example:

docker run img /bin/bash -c "ls -1 | wc -l"

But, without invoking the shell in the remote the output will be redirected to the local terminal.

Use the TextInputLayout provided by the Material Components Library:

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Label">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </com.google.android.material.textfield.TextInputLayout>

For mocking of void methods try out below:

//Kotlin Syntax

 Mockito.`when`(voidMethodCall())
           .then {
                Unit //Do Nothing
            }

Try this:

$NameRegex = "chalmw-dm"  
$NameR = "$($NameRegex)*"
Get-ADComputer -Filter {name -like $NameR -and Enabled -eq $True}

The thread's a little old. But from the title I thought it had promise for my needs. Unfortunately, my structure didn't lend itself easily to the nth-of-type solution. Here's a Thymeleaf solution.

.back-red {
  background-color:red;
}
.back-green {
  background-color:green;
}


<div class="container">
    <div class="row" th:with="employees=${{'emp-01', 'emp-02', 'emp-03', 'emp-04', 'emp-05', 'emp-06', 'emp-07', 'emp-08', 'emp-09', 'emp-10', 'emp-11', 'emp-12'}}">
        <div class="col-md-4 col-sm-6 col-xs-12" th:each="i:${#numbers.sequence(0, #lists.size(employees))}" th:classappend'(${i} % 2) == 0?back-red:back-green"><span th:text="${emplyees[i]}"></span></div>
    </div>
</div>

Simply add the following line in your build.gradle project

dependencies {
    ...
    compile 'com.android.support:cardview-v7:24.0.0'
}

And sync the project with gradle.

A simpler solution that works for me:

=COUNTIFS(A:A;"<>"&"")

It counts both numbers, strings, dates, etc that are not empty

Just to quote Boot Docs:

You can set spring.data.mongodb.uri property to change the url, or alternatively specify a host/port. For example, you might declare the following in your application.properties:

spring.data.mongodb.host=mongoserver
spring.data.mongodb.port=27017

All available options for spring.data.mongodb prefix are fields of MongoProperties:

private String host;

private int port = DBPort.PORT;

private String uri = "mongodb://localhost/test";

private String database;

private String gridFsDatabase;

private String username;

private char[] password;

I had the same problem, the cause was that I forgot to specify the branch

git push myorigin feature/23082018_my-feature_eb

Clean-Rebuild solution worked for me.

It's a bit of a guess but could the quotes around happy be the problem? There have been some problems in the past where Android would either add or not recognize quotes around an SSID. Try setting up the hosted network connection again, but without the quotes that we see in the output for netsh wlan show hostednetwork.

If upload_file is meant to be the file, use:

files = {'upload_file': open('file.txt','rb')}
values = {'DB': 'photcat', 'OUT': 'csv', 'SHORT': 'short'}

r = requests.post(url, files=files, data=values)

and requests will send a multi-part form POST body with the upload_file field set to the contents of the file.txt file.

The filename will be included in the mime header for the specific field:

>>> import requests
>>> open('file.txt', 'wb')  # create an empty demo file
<_io.BufferedWriter name='file.txt'>
>>> files = {'upload_file': open('file.txt', 'rb')}
>>> print(requests.Request('POST', 'http://example.com', files=files).prepare().body.decode('ascii'))
--c226ce13d09842658ffbd31e0563c6bd
Content-Disposition: form-data; name="upload_file"; filename="file.txt"


--c226ce13d09842658ffbd31e0563c6bd--

Note the filename="file.txt" parameter.

You can use a tuple for the files mapping value, with between 2 and 4 elements, if you need more control. The first element is the filename, followed by the contents, and an optional content-type header value and an optional mapping of additional headers:

files = {'upload_file': ('foobar.txt', open('file.txt','rb'), 'text/x-spam')}

This sets an alternative filename and content type, leaving out the optional headers.

If you are meaning the whole POST body to be taken from a file (with no other fields specified), then don't use the files parameter, just post the file directly as data. You then may want to set a Content-Type header too, as none will be set otherwise. See Python requests - POST data from a file.

In a code there is a mistake:

void deleteNode ()
{
    for (Node * temp = head; temp! = NULL; temp = temp-> next)
        delete head;
}

It is necessary so:

for (; head != NULL; )
{
    Node *temp = head;
    head = temp->next;

    delete temp;
}

The first thing to check is which location pip is resolving to:

which pip

if you are in a virtualenv you would expect this to give you something like:

/path/to/virtualenv/.name_of_virtualenv/bin/pip

However it may be the case that it's resolving to your system pip for some reason. For example you may see this from within your virtualenv (this is bad):

/usr/local/bin/pip (or anything that isn't in your virtualenv path).

To solve this check your pipconfig in:

~/.pipconf
~/.conf/pip
/etc/pip.conf

and make sure that there is nothing that is coercing your Python path or your pip path (this fixed it for me).

Then try starting a new terminal and rebuild your virtualenv (delete then create it again)

Following short code can help:

df3 = df3.rename(columns={c: c.replace(' ', '') for c in df3.columns})

Remove spaces from columns.

For a project of mine, I needed to create intervals for time-series modeling, and to make the procedure more efficient I created tsmoothie: A python library for time-series smoothing and outlier detection in a vectorized way.

It provides different smoothing algorithms together with the possibility to computes intervals.

Here I use a ConvolutionSmoother but you can also test it others.

import numpy as np
import matplotlib.pyplot as plt
from tsmoothie.smoother import *

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2

# operate smoothing
smoother = ConvolutionSmoother(window_len=5, window_type='ones')
smoother.smooth(y)

# generate intervals
low, up = smoother.get_intervals('sigma_interval', n_sigma=2)

# plot the smoothed timeseries with intervals
plt.figure(figsize=(11,6))
plt.plot(smoother.smooth_data[0], linewidth=3, color='blue')
plt.plot(smoother.data[0], '.k')
plt.fill_between(range(len(smoother.data[0])), low[0], up[0], alpha=0.3)

I point out also that tsmoothie can carry out the smoothing of multiple timeseries in a vectorized way

In Fedora 21 and up, you simply open a terminal and install the Ruby Development files as root.

dnf install ruby-devel

If it is simple application then getSystemResourceAsStream can also be used.

try (InputStream inputStream = ClassLoader.getSystemResourceAsStream("config.properties"))..

There isn't any big deal in your above snippet, but imagine a function with a few more arguments and quite a few more lines of code. Then you decide to rename your data argument as yadda, but miss one of the places it is used in the function's body... Now data refers to the global, and you start having weird behaviour - where you would have a much more obvious NameError if you didn't have a global name data.

Also remember that in Python everything is an object (including modules, classes and functions), so there's no distinct namespaces for functions, modules or classes. Another scenario is that you import function foo at the top of your module, and use it somewhere in your function body. Then you add a new argument to your function and named it - bad luck - foo.

Finally, built-in functions and types also live in the same namespace and can be shadowed the same way.

None of this is much of a problem if you have short functions, good naming and a decent unit test coverage, but well, sometimes you have to maintain less than perfect code and being warned about such possible issues might help.

Not so graceful, but the very much simple in implementation solution - using global variable.

In the "first" file:

window.myApp = angular.module("myApp", [])
....

in the "second" , "third", etc:

myApp.controller('MyController', function($scope) {
    .... 
    }); 

Transforming with XSLT 3.0 is the only proper way to do it, as far as I can tell. It is guaranteed to produce valid XML, and a nice structure at that. https://www.w3.org/TR/xslt/#json

I found I had the same error. I was compiling a code with both lapack and blas. When I switched the order that the two libraries were called the error went away.

"LAPACK_LIB = -llapack -lblas" worked where "LAPACK_LIB = -lblas -llapack" gave the error described above.

Thanks for all your help! @Svetoslav Tsolov had it very close, but I was still getting an error, until I figured out the closing parenthesis was in the wrong place. Here's the final query that works:

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
(CASE WHEN dbo.EU_Admin3.EUID IS NULL THEN dbo.EU_Admin2.EUID ELSE dbo.EU_Admin3.EUID END) AS EUID
FROM dbo.AdminID 

LEFT OUTER JOIN dbo.EU_Admin2
ON dbo.AdminID.DistrictID = dbo.EU_Admin2.DistrictID

LEFT OUTER JOIN dbo.EU_Admin3
ON dbo.AdminID.ADMIN3_ID = dbo.EU_Admin3.ADMIN3_ID

We can mock list properly for foreach loop. Please find below code snippet and explanation.

This is my actual class method where I want to create test case by mocking list. this.nameList is a list object.

public void setOptions(){
    // ....
    for (String str : this.nameList) {
        str = "-"+str;
    }
    // ....
}

The foreach loop internally works on iterator, so here we crated mock of iterator. Mockito framework has facility to return pair of values on particular method call by using Mockito.when().thenReturn(), i.e. on hasNext() we pass 1st true and on second call false, so that our loop will continue only two times. On next() we just return actual return value.

@Test
public void testSetOptions(){
    // ...
    Iterator<SampleFilter> itr = Mockito.mock(Iterator.class);
    Mockito.when(itr.hasNext()).thenReturn(true, false);
    Mockito.when(itr.next()).thenReturn(Mockito.any(String.class);  

    List mockNameList = Mockito.mock(List.class);
    Mockito.when(mockNameList.iterator()).thenReturn(itr);
    // ...
}

In this way we can avoid sending actual list to test by using mock of list.

To activate the installRelease task, you simply need a signingConfig. That is all.

From http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Android-tasks:

Finally, the plugin creates install/uninstall tasks for all build types (debug, release, test), as long as they can be installed (which requires signing).

Here is what you want:

Install tasks
-------------
installDebug - Installs the Debug build
installDebugTest - Installs the Test build for the Debug build
installRelease - Installs the Release build
uninstallAll - Uninstall all applications.
uninstallDebug - Uninstalls the Debug build
uninstallDebugTest - Uninstalls the Test build for the Debug build
uninstallRelease - Uninstalls the Release build   <--- release

Here is how to obtain the installRelease task:

Example build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}

apply plugin: 'com.android.application'

android {
  compileSdkVersion 22
  buildToolsVersion '22.0.1'

  defaultConfig {
    applicationId 'demo'
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName '1.0'
  }

  signingConfigs {
      release {
          storeFile <file>
          storePassword <password>
          keyAlias <alias>
          keyPassword <password>
      }
  }

  buildTypes {
    release {
        signingConfig signingConfigs.release
    }
  }
}

Best way to design table is add one temporary row as auto increment and keep as primary key. So we can avoid such above issues.

I just found a solution for jaxrs-ri-2.16 - simply use

String output = response.readEntity(String.class)

this delivers the content as expected.

cd has a parameter /d, which will change drive and path with one command:

cd /d d:\temp

( see cd /?)

So the solution to the original problem is that you don't need both the "@see" and the "{@link...}" references on the same line. The "@link" tag is self-sufficient and, as noted, you can put it anywhere in the javadoc block. So you can mix the two approaches:

/**
 * some javadoc stuff
 * {@link com.my.package.Class#method()}
 * more stuff
 * @see com.my.package.AnotherClass
 */

The box model is something every web-developer should know about. working with percents for sizes and pixels for padding/margin just doesn't work. There always is a resolution at which it doesn't look good (e.g. giving a width of 90% and a padding/margin of 10px in a div with a width of under 100px).

Check this out (using micro.pravi's code): http://jsbin.com/umeduh/2

<div id="container">
    <div class="left">
        <div class="content">
            left
        </div>
    </div>
    <div class="right">
        <div class="content">
            right
            <textarea>Check me out!</textarea>
        </div>
    </div>
</div>

The <div class="content"> are there so you can use padding and margin without screwing up the floats.

this is the most important part of the CSS:

textarea {
    display: block;
    width: 100%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}

Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.

For your task: use INSERT...SELECT statement which will help you to copy data from one table to another using only one query.

INSERT ... SELECT Syntax.

For me, it was due to the "return type" of the test method. It should be "void"

Now, I just started programing about a week ago, so nothing fancy, but I had this as a problem and came up with this, which may be easier for people who are just getting into programing to understand. It uses Euclid's method like in previous examples.

public class GCD {
  public static void main(String[] args){
    int x = Math.max(Integer.parseInt(args[0]),Integer.parseInt(args[1]));    
    int y = Math.min(Integer.parseInt(args[0]),Integer.parseInt(args[1]));     
    for (int r = x % y; r != 0; r = x % y){
      x = y;
      y = r;
    }
    System.out.println(y);
  }
}

It is not guaranteed that the slicing returns a view or a copy. You can do

df['column'] = df['column'].fillna(value)

I had a same scenario where I would open a new modal on a button click. Once done, I want to completely remove it from my page... I use remove to delete the modal.. On button click I would check if modal exists , and if true I would destroy it and create a new modal ..

$("#wizard").click(function() {
    /* find if wizard is already open */
    if($('.wizard-modal').length) {
        $('.wizard-modal').remove();
    }
});

The Pixastic library does exactly what you want. However, it will only work on browsers that have canvas support. For those older browsers, you'll either need to:

1. supply a server-side fallback, or
2. tell the user that you're very sorry, but he'll need to get a more modern browser.

Of course, option #2 isn't very user-friendly. However, if your intent is to provide a pure client-only tool and/or you can't support a fallback back-end cropper (e.g. maybe you're writing a browser extension or offline Chrome app, or maybe you can't afford a decent hosting provider that provides image manipulation libraries), then it's probably fair to limit your user base to modern browsers.

EDIT: If you don't want to learn Pixastic, I have added a very simple cropper on jsFiddle here. It should be possible to modify and integrate and use the drawCroppedImage function with Jcrop.

The error you posted can happen when you're using a clause in the GROUP BY statement without including it in the select.

Example

This one works!

     SELECT t.device,
            SUM(case when transits.direction = 1 then 1 else 0 end) ,
            SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t 
            where t.device in ('A','B') group by t.device

This one not (omitted t.device from the select)

     SELECT 
            SUM(case when transits.direction = 1 then 1 else 0 end) ,
            SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t 
            where t.device in ('A','B') group by t.device

This will produce your error complaining that I'm grouping for something that is not included in the select

Please, provide all the query to get more support.

My solution to this problem, use route.current in the angular template.

As you have the /tasks route to highlight in your menu, you can add your own property menuItem to the routes declared by your module:

$routeProvider.
  when('/tasks', {
    menuItem: 'TASKS',
    templateUrl: 'my-templates/tasks.html',
    controller: 'TasksController'
  );

Then in your template tasks.htmlyou can use following ng-class directive:

<a href="app.html#/tasks" 
    ng-class="{active : route.current.menuItem === 'TASKS'}">Tasks</a>

In my opinion, this is much cleaner than all proposed solutions.

I have also used following link as others have suggested you for bluetooth communication.

http://developer.android.com/guide/topics/connectivity/bluetooth.html

The thing is all you need is a class BluetoothChatService.java

this class has following threads:

1. Accept
2. Connecting
3. Connected

Now when you call start function of the BluetoothChatService like:

mChatService.start();

It starts accept thread which means it will start looking for connection.

Now when you call

mChatService.connect(<deviceObject>,false/true);

Here first argument is device object that you can get from paired devices list or when you scan for devices you will get all the devices in range you can pass that object to this function and 2nd argument is a boolean to make secure or insecure connection.

connect function will start connecting thread which will look for any device which is running accept thread.

When such a device is found both accept thread and connecting thread will call connected function in BluetoothChatService:

connected(mmSocket, mmDevice, mSocketType);

this method starts connected thread in both the devices: Using this socket object connected thread obtains the input and output stream to the other device. And calls read function on inputstream in a while loop so that it's always trying read from other device so that whenever other device send a message this read function returns that message.

BluetoothChatService also has a write method which takes byte[] as input and calls write method on connected thread.

mChatService.write("your message".getByte());

write method in connected thread just write this byte data to outputsream of the other device.

public void write(byte[] buffer) {
   try {
       mmOutStream.write(buffer);
    // Share the sent message back to the UI Activity
    // mHandler.obtainMessage(
    // BluetoothGameSetupActivity.MESSAGE_WRITE, -1, -1,
    // buffer).sendToTarget();
    } catch (IOException e) {
    Log.e(TAG, "Exception during write", e);
     }
}

Now to communicate between two devices just call write function on mChatService and handle the message that you will receive on the other device.

Both styles, with a touch of tweaking, would work.

The first method uses a Javascript Constructor, which like most things has pros and cons.

 // By convention, constructors start with an upper case letter
function MakePerson(name,age) {
  // The magic variable 'this' is set by the Javascript engine and points to a newly created object that is ours.
  this.name = name;
  this.age = age;
  this.occupation = "Hobo";
}
var jeremy = new MakePerson("Jeremy", 800);

On the other hand, your other method is called the 'Revealing Closure Pattern' if I recall correctly.

function makePerson(name2, age2) {
  var name = name2;
  var age = age2;

  return {
    name: name,
    age: age
  };
}

For my case, this error was triggered because of a huge select query (hundreds of thousands of returned results).

It arose immediately after adding millions of records in my Database to test the scalability of WordPress, so it was the only probable reason for me.

builder.setAutoCancel(true);

Tested on Android 9 also.

I ran into this problem, and my solution was moreso that www-data didn't own the proper folders, and instead I set it for one of the users to own it. (I was trying to do a bit of fancy, but erroneous trickery to get ftp to play nicely.)

After running:

chown -R www-data:www-data /var/www/html

The machine started serving data again. You can see who currently owns the folder by means of

ls -l /var/www/html

These solutions only partially worked for me because I was doing multiple aggregations. Here is a sample output of my grouped by that I wanted to convert to a dataframe:

Because I wanted more than the count provided by reset_index(), I wrote a manual method for converting the image above into a dataframe. I understand this is not the most pythonic/pandas way of doing this as it is quite verbose and explicit, but it was all I needed. Basically, use the reset_index() method explained above to start a "scaffolding" dataframe, then loop through the group pairings in the grouped dataframe, retrieve the indices, perform your calculations against the ungrouped dataframe, and set the value in your new aggregated dataframe.

df_grouped = df[['Salary Basis', 'Job Title', 'Hourly Rate', 'Male Count', 'Female Count']]
df_grouped = df_grouped.groupby(['Salary Basis', 'Job Title'], as_index=False)

# Grouped gives us the indices we want for each grouping
# We cannot convert a groupedby object back to a dataframe, so we need to do it manually
# Create a new dataframe to work against
df_aggregated = df_grouped.size().to_frame('Total Count').reset_index()
df_aggregated['Male Count'] = 0
df_aggregated['Female Count'] = 0
df_aggregated['Job Rate'] = 0

def manualAggregations(indices_array):
    temp_df = df.iloc[indices_array]
    return {
        'Male Count': temp_df['Male Count'].sum(),
        'Female Count': temp_df['Female Count'].sum(),
        'Job Rate': temp_df['Hourly Rate'].max()
    }

for name, group in df_grouped:
    ix = df_grouped.indices[name]
    calcDict = manualAggregations(ix)

    for key in calcDict:
        #Salary Basis, Job Title
        columns = list(name)
        df_aggregated.loc[(df_aggregated['Salary Basis'] == columns[0]) & 
                          (df_aggregated['Job Title'] == columns[1]), key] = calcDict[key]

If a dictionary isn't your thing, the calculations could be applied inline in the for loop:

    df_aggregated['Male Count'].loc[(df_aggregated['Salary Basis'] == columns[0]) & 
                                (df_aggregated['Job Title'] == columns[1])] = df['Male Count'].iloc[ix].sum()

This is my solution in java 8:

 public static Boolean isValidCity(String cityCode) {
        return Arrays.stream(CITY_ENUM.values())
                .map(CITY_ENUM::getCityCode)
                .anyMatch(cityCode::equals);
 }

Q. List the name of each show, and the number of different times it has been held. List the show which has been held most often first.

event_id show_id event_name judge_id
0101    01  Dressage        01
0102    01  Jumping         02
0103    01  Led in          01
0201    02  Led in          02
0301    03  Led in          01
0401    04  Dressage        04
0501    05  Dressage        01
0502    05  Flag and Pole   02

Ans:

select event_name, count(show_id) as held_times from event 
group by event_name 
order by count(show_id) desc

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

test output:

1,2,
1,3,
1,4,
1,5,
2,3,
2,4,
2,5,
3,4,
3,5,
4,5,

I have polished this missing subclass of QLabel. It is awesome and works well.

{
    pix = p;
    QLabel::setPixmap(scaledPixmap());
}

int AspectRatioPixmapLabel::heightForWidth( int width ) const

    return pix.isNull() ? this->height() : ((qreal)pix.height()*width)/pix.width();
}

    int w = this->width();
    return QSize( w, heightForWidth(w) );
}

QPixmap AspectRatioPixmapLabel::scaledPixmap() const

}

void AspectRatioPixmapLabel::resizeEvent(QResizeEvent * e)

Hope that helps! (Updated resizeEvent, per @dmzl's answer)

You can achieve this more universally by applying the following CSS:

html,
body {
  height: 100%;
  width: 100%;
  overflow: auto;
}

This allows your content, whatever it is, to become scrollable within body, but be aware that the scrolling context where scroll event is fired is now document.body, not window.

In the detached window (Tool Options), the name of the view (Paintbrush) is a grab-bar.

Put your cursor over the grab-bar, click and drag it to the dock area in the main window in order to reattach it to the main window.

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

I am using blueJ for java programming. There is a way to clear the screen of it's terminal window. Try this:-

System.out.print ('\f');

this will clear whatever is printed before this line. But this does not work in command prompt.

Other then the obvious problems I had another one that I couldn't fix regardless of including all possible JARs, dependancies and annotations in Spring servlet. Eventually I found that I have wrong file extension by that I mean I had two separate servlet running in same container and I needed to map to different file extensions where one was ".do" and the other as used for subscriptions was randomly named ".sub". All good but SUB is valid file extension normally used for films subtitle files and thus Tomcat was overriding the header and returning something like "text/x-dvd.sub..." so all was fine but the application was expecting JSON but getting Subtitles thus all I had to do is change the mapping in my web.xml file I've added:

<mime-mapping>
    <extension>sub</extension>
    <mime-type>application/json</mime-type>
</mime-mapping>

Just apply the style attribute to the tr tag. In the case of multiple tr tags, you will have to apply the style to each element, or wrap them in a tbody tag:

<table>
  <tr><th>Test Table</th><tr>
  <tbody style="display:none">
    <tr><td>123456789</td><tr>
    <tr><td>123456789</td><tr>
    <tr><td>123456789</td><tr>
  </tbody>
</table>

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

Elaborating on the answer @douwe here is where you would put a timeout on a http request.

// TYPICAL REQUEST
var req = https.get(http_options, function (res) {                                                                                                             
    var data = '';                                                                                                                                             

    res.on('data', function (chunk) { data += chunk; });                                                                                                                                                                
    res.on('end', function () {
        if (res.statusCode === 200) { /* do stuff with your data */}
        else { /* Do other codes */}
    });
});       
req.on('error', function (err) { /* More serious connection problems. */ }); 

// TIMEOUT PART
req.setTimeout(1000, function() {                                                                                                                              
    console.log("Server connection timeout (after 1 second)");                                                                                                                  
    req.abort();

this.abort() is also fine.

I had to add the follow lines to my windows path to fix this. CMAKE should set the correct paths on install otherwise as long as you check the box. This is likely to be a different solution depending on the myriad of versions that are possible to install.

update:

I found the terms of use from Google Map:

Section 10.5

No caching or storage. You will not pre-fetch, cache, index, or store any Content to be used outside the Service, except that you may store limited amounts of Content solely for the purpose of improving the performance of your Maps API Implementation due to network latency (and not for the purpose of preventing Google from accurately tracking usage), and only if such storage: is temporary (and in no event more than 30 calendar days); is secure; does not manipulate or aggregate any part of the Content or Service; and does not modify attribution in any way.

It means we can cache for limited time actually

I have a few tricks and work arounds to interesting 'features' of xtable and Latex that I'll share here.

Trick #1: Removing Duplicates in Columns and Trick #2: Using Booktabs

First, load packages and define my clean function

<<label=first, include=FALSE, echo=FALSE>>= 
    library(xtable)
    library(plyr)

    cleanf <- function(x){     
        oldx <- c(FALSE, x[-1]==x[-length(x)])  
        # is the value equal to the previous?    
        res <- x
        res[oldx] <- NA
        return(res)} 

Now generate some fake data

data<-data.frame(animal=sample(c("elephant", "dog", "cat", "fish", "snake"), 100,replace=TRUE),
            colour=sample(c("red", "blue", "green", "yellow"), 100,replace=TRUE),
            size=rnorm(100,mean=500, sd=150),
            age=rlnorm(100, meanlog=3, sdlog=0.5))

    #generate a table
    datatable<-ddply(data, .(animal, colour), function(df) {
                return(data.frame(size=mean(df$size), age=mean(df$age)))
            })

Now we can generate a table, and use the clean function to remove duplicate entries in the label columns.

cleandata<-datatable
cleandata$animal<-cleanf(cleandata$animal)
cleandata$colour<-cleanf(cleandata$colour)
@ 

this is a normal xtable

<<label=normal, results=tex, echo=FALSE>>=
print(
    xtable(
        datatable
        ),
        tabular.environment='longtable',
        latex.environments=c("center"), 
        floating=FALSE, 
        include.rownames=FALSE
    )
@ 

this is a normal xtable where a custom function has turned duplicates to NA

<<label=cleandata, results=tex, echo=FALSE>>=
print(
    xtable(
        cleandata
        ),
        tabular.environment='longtable',
        latex.environments=c("center"), 
        floating=FALSE, 
        include.rownames=FALSE
    )
@ 

This table uses the booktab package (and needs a \usepackage{booktabs} in the headers)

\begin{table}[!h] 
        \centering
        \caption{table using booktabs.}
        \label{tab:mytable}
<<label=booktabs, echo=F,results=tex>>= 
            mat <- xtable(cleandata,digits=rep(2,ncol(cleandata)+1))
            foo<-0:(length(mat$animal))
            bar<-foo[!is.na(mat$animal)]
            print(mat, 
                  sanitize.text.function = function(x){x},
                  floating=FALSE,
                  include.rownames=FALSE,
                  hline.after=NULL, 
                  add.to.row=list(pos=list(-1,bar,nrow(mat)), 
                  command=c("\\toprule ", "\\midrule ", "\\bottomrule ")))
  #could extend this with \cmidrule to have a partial line over
  #a sub category column and \addlinespace to add space before a total row
@ 

extern std::pair<std::string_view, Base*(*)()> const factories[2];

decltype(factories) factories{
  {"blah", []() -> Base*{return new Blah;}},
  {"foo", []() -> Base*{return new Foo;}}
};

In Linux, run file on the Eclipse executable, like this:

$ file /usr/bin/eclipse
eclipse: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.0, not stripped

It's as simple as is:

WebView webview = (WebView) findViewById(R.id.webview);
webview.loadUrl("file:///android_asset/some.html");

And your some.html needs to contain something like:

<link rel="stylesheet" type="text/css" href="style.css" />

If your modulus is prime (you call it p) then you may simply compute:

y = x**(p-2) mod p  # Pseudocode

Or in Python proper:

y = pow(x, p-2, p)

Here is someone who has implemented some number theory capabilities in Python: http://www.math.umbc.edu/~campbell/Computers/Python/numbthy.html

Here is an example done at the prompt:

m = 1000000007
x = 1234567
y = pow(x,m-2,m)
y
989145189L
x*y
1221166008548163L
x*y % m
1L

Having issues building with ANT? Keep reading

If ant -f core/build.xml says something like:

Unable to locate tools.jar. Expected to find it in
C:\Program Files\Java\jre6\lib\tools.jar

then set your JAVA_HOME environment variable to the proper java folder. I found tools.jar in my (for Windows):

C:\Program Files\Java\jdk1.6.0_21\lib

so I set my JAVA_HOME to:

C:\Progra~1\Java\jdk1.6.0_25

the reason for the shorter syntax I found at some site which says:

"It is strongly advised that you choose an installation directory that does not include spaces in the path name (e.g., do NOT install in C:\Program Files). If Java is installed in such a directory, it is critical to set the JAVA_HOME environment variable to a path that does not include spaces (e.g., C:\Progra~1); failure to do this will result in exceptions thrown by some programs that depend on the value of JAVA_HOME."

I then relaunched cmd (important because DOS shell only reads env vars upon launching, so changing an env var will require you to use a new shell to get the updated value)

and finally the ant -f core/build.xml worked.

Some devices will only let the debugger attach if the application has the android.permission.SET_DEBUG_APP permission set in its manifest file:

<manifest>
  <uses-permission android:name="android.permission.SET_DEBUG_APP"></uses-permission>

@will's method is the best. Just add few lines about the details for the people didn't use ExcelDNA before like me.

Download Excel-DNA IntelliSense from https://github.com/Excel-DNA/IntelliSense/releases

There are two version, one is for 64, check your Excel version. For my case, I'm using 64 version.

Open Excel/Developer/Add-Ins/Browse and select ExcelDna.IntelliSense64.xll.

Insert a new sheet, change name to "IntelliSense", add function description, as https://github.com/Excel-DNA/IntelliSense/wiki/Getting-Started

Then enjoy! :)

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

Use the write()-Method of the Popup's document to put your markup there:

$.post(url, function (data) {
    var w = window.open('about:blank');
    w.document.open();
    w.document.write(data);
    w.document.close();
});

You can add a DLL (or EXE) to a project only if it is a .NET assembly. If it's not you will see this error message.

regsvr32 also makes certain assumptions about the structure and exported function in the DLL. It has been a while since I used it but it has to do with registering COM servers so certain entry points need to be available. If regsvr32 fails the DLL doesn't provide those entry points and the DLL does not contain a COM component.

You only chance for using the DLL is to import it like any other non-.NET binary, e.g. when you use certain Win32 APIs. There is an old MSDN Magazine Article that might be helpful. See the following update for info where to get the article.

Update 12 March 2018: The link to the MSDN Magazine no longer works as it used to in August 2010. The article by Jason Clark is titled ".NET Column: Calling Win32 DLLs in C# with P/Invoke". It was published in the July 2010 issue of MSDN Magazine. The "Wayback Machine" has the article here at the moment (formatting is limited). The entire MSDN Magazine issue July 2010 is available here (HCM format only, instructions for how to use HCM files here).

Simply chain the replace functions like this

strs = "abc&def#ghi"
print strs.replace('&', '\&').replace('#', '\#')
# abc\&def\#ghi

If the replacements are going to be more in number, you can do this in this generic way

strs, replacements = "abc&def#ghi", {"&": "\&", "#": "\#"}
print "".join([replacements.get(c, c) for c in strs])
# abc\&def\#ghi

This solution is very flexible and uses existing Java functions:

• Completely based on generics
• Uses java.util.Collections for finding and inserting list elements
• Option to use a custom Comparator for list sorting

Some notes:

• This sorted list is not synchronized since it inherits from java.util.ArrayList. Use Collections.synchronizedList if you need this (refer to the Java documentation for java.util.ArrayList for details).
• The initial solution was based on java.util.LinkedList. For better performance, specifically for finding the insertion point (Logan's comment) and quicker get operations (https://dzone.com/articles/arraylist-vs-linkedlist-vs), this has been changed to java.util.ArrayList.

For what it's worth, my groovy spike seems to work with both UTF-8 and ISO-8859-1 character encodings. Not sure what will happen when a non zxing decoder tries to decode the UTF-8 encoded image though... probably varies depending on the device.

An alternative also it to use the Aggregate() extension method.

var sum = arr.Aggregate((temp, x) => temp+x);

I was having this problem in Safari and Chrome (Mac) and discovered that .scrollTop would work on $("body") but not $("html, body"), FF and IE however works the other way round. A simple browser detect fixes the issue:

if($.browser.safari)
    bodyelem = $("body")
else
    bodyelem = $("html,body")

bodyelem.scrollTop(100)

The jQuery browser value for Chrome is Safari, so you only need to do a detect on that.

Hope this helps someone.

Use this to close it instead:

$.fn.fancybox.close();

Judging from the fancybox source code, that is how they handle closing it internally.

A slight modification of this to change the \voffset works for me:

\newenvironment{changemargin}[1]{
  \begin{list}{}{
    \setlength{\voffset}{#1}
  }
  \item[]}{\end{list}}

And then put your figures in a \begin{changemargin}{-1cm}...\end{changemargin} environment.

There's no NotifyIcon for WPF.

A colleague of mine used this freely available library to good effect:

• http://www.hardcodet.net/wpf-notifyicon (blog post)

• http://visualstudiogallery.msdn.microsoft.com/aacbc77c-4ef6-456f-80b7-1f157c2909f7/

The default behavior of Eclipse when compiling code with errors in it, is to generate byte code throwing the exception you see, allowing the program to be run. This is possible as Eclipse uses its own built-in compiler, instead of javac from the JDK which Apache Maven uses, and which fails the compilation completely for errors. If you use Eclipse on a Maven project which you are also working with using the command line mvn command, this may happen.

The cure is to fix the errors and recompile, before running again.

The setting is marked with a red box in this screendump:

You can use the Tanuki wrapper to spawn a process with POSIX spawn instead of fork. http://wrapper.tanukisoftware.com/doc/english/child-exec.html

The WrapperManager.exec() function is an alternative to the Java-Runtime.exec() which has the disadvantage to use the fork() method, which can become on some platforms very memory expensive to create a new process.

Regarding de-duping things your string split and match is great first cut. If there are known items about the data that can be leveraged to reduce workload and/or produce better results, it is always good to take advantage of them. Bear in mind that often for de-duping it is impossible to entirely eliminate manual work, although you can make that much easier by catching as much as you can automatically and then generating reports of your "uncertainty cases."

Regarding name matching: SOUNDEX is horrible for quality of matching and especially bad for the type of work you are trying to do as it will match things that are too far from the target. It's better to use a combination of double metaphone results and the Levenshtein distance to perform name matching. With appropriate biasing this works really well and could probably be used for a second pass after doing a cleanup on your knowns.

You may also want to consider using an SSIS package and looking into Fuzzy Lookup and Grouping transformations (http://msdn.microsoft.com/en-us/library/ms345128(SQL.90).aspx).

Using SQL Full-Text Search (http://msdn.microsoft.com/en-us/library/cc879300.aspx) is a possibility as well, but is likely not appropriate to your specific problem domain.

Here are the steps I followed to recover from a corrupt blob object.

1) Identify corrupt blob

git fsck --full
  error: inflate: data stream error (incorrect data check)
  error: sha1 mismatch 241091723c324aed77b2d35f97a05e856b319efd
  error: 241091723c324aed77b2d35f97a05e856b319efd: object corrupt or missing
  ...

Corrupt blob is 241091723c324aed77b2d35f97a05e856b319efd

2) Move corrupt blob to a safe place (just in case)

mv .git/objects/24/1091723c324aed77b2d35f97a05e856b319efd ../24/

3) Get parent of corrupt blob

git fsck --full
  Checking object directories: 100% (256/256), done.
  Checking objects: 100% (70321/70321), done.
  broken link from    tree 0716831e1a6c8d3e6b2b541d21c4748cc0ce7180
              to    blob 241091723c324aed77b2d35f97a05e856b319efd

Parent hash is 0716831e1a6c8d3e6b2b541d21c4748cc0ce7180.

4) Get file name corresponding to corrupt blob

git ls-tree 0716831e1a6c8d3e6b2b541d21c4748cc0ce7180
  ...
  100644 blob 241091723c324aed77b2d35f97a05e856b319efd    dump.tar.gz
  ...

Find this particular file in a backup or in the upstream git repository (in my case it is dump.tar.gz). Then copy it somewhere inside your local repository.

5) Add previously corrupted file in the git object database

git hash-object -w dump.tar.gz

6) Celebrate!

git gc
  Counting objects: 75197, done.
  Compressing objects: 100% (21805/21805), done.
  Writing objects: 100% (75197/75197), done.
  Total 75197 (delta 52999), reused 69857 (delta 49296)

In trying to simulate a 'click' in unit tests with the jQuery UI spinner I could not get any of the previous answers to work. In particular, I was trying to simulate the 'spin' of selecting the down arrow. I looked at the jQuery UI spinner unit tests and they use the following method, which worked for me:

element.spinner( "widget" ).find( ".ui-spinner-up" ).mousedown().mouseup();

I think you're confused because you're running from the REPL, which automatically prints out the value returned when you call a function. In that case, you do get identical output whether you have a function that creates a value, prints it, and throws it away, or you have a function that creates a value and returns it, letting the REPL print it.

However, these are very much not the same thing, as you will realize when you call autoparts with another function that wants to do something with the value that autoparts creates.

On Windows add following lines to _vimrc

" store backup, undo, and swap files in temp directory
set directory=$HOME/temp//
set backupdir=$HOME/temp//
set undodir=$HOME/temp//

This worked for me

[ImageViewName setImage:[UIImage imageNamed: @"ImageName.png"]];

Make sure that the ImageView is declared properly in the .h file and is linked with the IB element.

I would do it by creating a variable that points to the nodes that have the proper value in Value1 then referring to t

<xsl:variable name="myVarANode" select="root//DataSet/Data[@Value1='2']" />
<xsl:value-of select="$myVarANode/@Value2"/>

Everyone else's answers are right too - more right in fact since I didn't notice the extra slash in your XPATH that would mess things up. Still, this will also work , and might work for different things, so keep this method in your toolbox.

Here is my take using Scala:

trait MergeSort {
  def mergeSort(ls: List[Int]): List[Int] = {
    def merge(ls1: List[Int], ls2: List[Int]): List[Int] =
      (ls1, ls2) match {
        case (_, Nil) => ls1
        case (Nil, _) => ls2
        case (lowsHead :: lowsTail, highsHead :: highsTail) =>
          if (lowsHead <= highsHead) lowsHead :: merge(lowsTail, ls2)
          else highsHead :: merge(ls1, highsTail)
      }

    ls match {
      case Nil => Nil
      case head :: Nil => ls
      case _ =>
        val (lows, highs) = ls.splitAt(ls.size / 2)
        merge(mergeSort(lows), mergeSort(highs))
    }
  }
}

object InversionCounterApp extends App with MergeSort {
  @annotation.tailrec
  def calculate(list: List[Int], sortedListZippedWithIndex: List[(Int, Int)], counter: Int = 0): Int =
    list match {
      case Nil => counter
      case head :: tail => calculate(tail, sortedListZippedWithIndex.filterNot(_._1 == 1), counter + sortedListZippedWithIndex.find(_._1 == head).map(_._2).getOrElse(0))
    }

  val list: List[Int] = List(6, 9, 1, 14, 8, 12, 3, 2)
  val sortedListZippedWithIndex: List[(Int, Int)] = mergeSort(list).zipWithIndex
  println("inversion counter = " + calculate(list, sortedListZippedWithIndex))
  // prints: inversion counter = 28 
}

So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.

Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

Happy coding.. :)

Thanks, Ayan

I would not use an explicit cursor to do this. Steve F. no longer advises people to use explicit cursors when an implicit cursor could be used.

The method with count(*) is unsafe. If another session deletes the row that met the condition after the line with the count(*), and before the line with the select ... into, the code will throw an exception that will not get handled.

The second version from the original post does not have this problem, and it is generally preferred.

That said, there is a minor overhead using the exception, and if you are 100% sure the data will not change, you can use the count(*), but I recommend against it.

I ran these benchmarks on Oracle 10.2.0.1 on 32 bit Windows. I am only looking at elapsed time. There are other test harnesses that can give more details (such as latch counts and memory used).

if you want to use the each function, it should look like this:

$('#formId').children().each( 
  function(){
    //access to form element via $(this)
  }
);

Just switch out the closing curly bracket for a close paren. Thanks for pointing it out, jobscry, you saved me some time.

How can I check if I have listed all the dependencies correctly?

The pbuilder is an excellent tool for checking both build dependencies and dependencies by setting up a clean base system within a chroot environment. By compiling the package within pbuilder, you can easily check the build dependencies, and by testing it within a pbuilder environment, you can check the dependencies.

Along with Bootstrap 3 I used this code. The second set of rules just undo what bootstrap does for focus/active buttons:

button::-moz-focus-inner {
  border: 0;    /*removes dotted lines around buttons*/
}

.btn.active.focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn:active:focus, .btn:focus{
  outline:0;
}

NOTE that your custom css file should come after Bootstrap css file in your html code to override it.

No need for third party tools when Android Studio can generate icons for us.

• File -> New -> Image Asset

• Then choose Launcher Icons as the Asset Type:

• Choose a High-res image for the Image file:

• Next -> Finish to generate icons

Finally update android:icon name field in AndroidManifest.xml if required.

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

This is a complete working Console solution based on the example provided in here:

class Program
{
    static string[] words1 = new string[] { "brown", "jumped", "the", "fox", "quick" };

    static void Main()
    {
        var result = Shuffle(words1);
        foreach (var i in result)
        {
            Console.Write(i + " ");
        }
        Console.ReadKey();
    }

   static string[] Shuffle(string[] wordArray) {
        Random random = new Random();
        for (int i = wordArray.Length - 1; i > 0; i--)
        {
            int swapIndex = random.Next(i + 1);
            string temp = wordArray[i];
            wordArray[i] = wordArray[swapIndex];
            wordArray[swapIndex] = temp;
        }
        return wordArray;
    }         
}

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

Return values (from a wrapping-function)

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

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

Exit codes as indicators

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

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

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

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

Stdout as your relay

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

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

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

Files as conveyors

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

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

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

Sockets as conveyors

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

Another thing to check - make sure you have the correct entities selected in both

Targets -> Your Target -> Build Settings -> Signing

and

Project -> Your Project -> Build Settings -> Code Signing Entity

I got this message when I had a full dev profile selected in one and a different (non-developer) Apple ID selected in the other, even with no entitlements requested in the app.

On my install, FontProperties only changes the text size, but it's still too large and spaced out. I found a parameter in pyplot.rcParams: legend.labelspacing, which I'm guessing is set to a fraction of the font size. I've changed it with

pyplot.rcParams.update({'legend.labelspacing':0.25})

I'm not sure how to specify it to the pyplot.legend function - passing

prop={'labelspacing':0.25}

or

prop={'legend.labelspacing':0.25}

comes back with an error.

You can use Pillow (Website, Documentation, GitHub, PyPI). Pillow has the same interface as PIL, but works with Python 3.

Installation

$ pip install Pillow

If you don't have administrator rights (sudo on Debian), you can use

$ pip install --user Pillow

Other notes regarding the installation are here.

Code

from PIL import Image
with Image.open(filepath) as img:
    width, height = img.size

Speed

This needed 3.21 seconds for 30336 images (JPGs from 31x21 to 424x428, training data from National Data Science Bowl on Kaggle)

This is probably the most important reason to use Pillow instead of something self-written. And you should use Pillow instead of PIL (python-imaging), because it works with Python 3.

Alternative #1: Numpy (deprecated)

I keep scipy.ndimage.imread as the information is still out there, but keep in mind:

imread is deprecated! imread is deprecated in SciPy 1.0.0, and [was] removed in 1.2.0.

import scipy.ndimage
height, width, channels = scipy.ndimage.imread(filepath).shape

Alternative #2: Pygame

import pygame
img = pygame.image.load(filepath)
width = img.get_width()
height = img.get_height()

If you are interested in processing Javascript on the server, there is a new open source library called Jint that allows you to execute server side Javascript. Basically it is a Javascript interpreter written in C#. I have been testing it and so far it looks quite promising.

Here's the description from the site:

Differences with other script engines:

Jint is different as it doesn't use CodeDomProvider technique which is using compilation under the hood and thus leads to memory leaks as the compiled assemblies can't be unloaded. Moreover, using this technique prevents using dynamically types variables the way JavaScript does, allowing more flexibility in your scripts. On the opposite, Jint embeds it's own parsing logic, and really interprets the scripts. Jint uses the famous ANTLR (http://www.antlr.org) library for this purpose. As it uses Javascript as its language you don't have to learn a new language, it has proven to be very powerful for scripting purposes, and you can use several text editors for syntax checking.

In response to the original question, you are using for/in incorrectly. In your code, key is the index. So, to get the value from the pseudo-array, you'd have to do list[key] and to get the id, you'd do list[key].id. But, you should not be doing this with for/in in the first place.

Summary (added in Dec 2018)

Do not ever use for/in to iterate a nodeList or an HTMLCollection. The reasons to avoid it are described below.

All recent versions of modern browsers (Safari, Firefox, Chrome, Edge) all support for/of iteration on DOM lists such nodeList or HTMLCollection.

Here's an example:

var list = document.getElementsByClassName("events");
for (let item of list) {
    console.log(item.id);
}

To include older browsers (including things like IE), this will work everywhere:

var list= document.getElementsByClassName("events");
for (var i = 0; i < list.length; i++) {
    console.log(list[i].id); //second console output
}

Explanation For Why You Should Not Use for/in

for/in is meant for iterating the properties of an object. That means it will return all iterable properties of an object. While it may appear to work for an array (returning array elements or pseudo-array elements), it can also return other properties of the object that are not what you are expecting from the array-like elements. And, guess what, an HTMLCollection or nodeList object can both have other properties that will be returned with a for/in iteration. I just tried this in Chrome and iterating it the way you were iterating it will retrieve the items in the list (indexes 0, 1, 2, etc...), but also will retrieve the length and item properties. The for/in iteration simply won't work for an HTMLCollection.

See http://jsfiddle.net/jfriend00/FzZ2H/ for why you can't iterate an HTMLCollection with for/in.

In Firefox, your for/in iteration would return these items (all the iterable properties of the object):

0
1
2
item
namedItem
@@iterator
length

Hopefully, now you can see why you want to use for (var i = 0; i < list.length; i++) instead so you just get 0, 1 and 2 in your iteration.

Following below is an evolution of how browsers have evolved through the time period 2015-2018 giving you additional ways to iterate. None of these are now needed in modern browsers since you can use the options described above.

Update for ES6 in 2015

Added to ES6 is Array.from() that will convert an array-like structure to an actual array. That allows one to enumerate a list directly like this:

"use strict";

Array.from(document.getElementsByClassName("events")).forEach(function(item) {
   console.log(item.id);
});

Working demo (in Firefox, Chrome, and Edge as of April 2016): https://jsfiddle.net/jfriend00/8ar4xn2s/

Update for ES6 in 2016

You can now use the ES6 for/of construct with a NodeList and an HTMLCollection by just adding this to your code:

NodeList.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator];
HTMLCollection.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator];

Then, you can do:

var list = document.getElementsByClassName("events");
for (var item of list) {
    console.log(item.id);
}

This works in the current version of Chrome, Firefox, and Edge. This works because it attaches the Array iterator to both the NodeList and HTMLCollection prototypes so that when for/of iterates them, it uses the Array iterator to iterate them.

Working demo: http://jsfiddle.net/jfriend00/joy06u4e/.

Second Update for ES6 in Dec 2016

As of Dec 2016, Symbol.iterator support has been built-in to Chrome v54 and Firefox v50 so the code below works by itself. It is not yet built-in for Edge.

var list = document.getElementsByClassName("events");
for (let item of list) {
    console.log(item.id);
}

Working demo (in Chrome and Firefox): http://jsfiddle.net/jfriend00/3ddpz8sp/

Third Update for ES6 in Dec 2017

As of Dec. 2017, this capability works in Edge 41.16299.15.0 for a nodeList as in document.querySelectorAll(), but not an HTMLCollection as in document.getElementsByClassName() so you have to manually assign the iterator to use it in Edge for an HTMLCollection. It is a total mystery why they'd fix one collection type, but not the other. But, you can at least use the result of document.querySelectorAll() with ES6 for/of syntax in current versions of Edge now.

I've also updated the above jsFiddle so it tests both HTMLCollection and nodeList separately and captures the output in the jsFiddle itself.

Fourth Update for ES6 in Mar 2018

Per mesqueeeb, Symbol.iterator support has been built-in to Safari too, so you can use for (let item of list) for either document.getElementsByClassName() or document.querySelectorAll().

Fifth Update for ES6 in Apr 2018

Apparently, support for iterating an HTMLCollection with for/of will be coming to Edge 18 in Fall 2018.

Sixth Update for ES6 in Nov 2018

I can confirm that with Microsoft Edge v18 (that is included in the Fall 2018 Windows Update), you can now iterate both an HTMLCollection and a NodeList with for/of in Edge.

So, now all modern browsers contain native support for for/of iteration of both the HTMLCollection and NodeList objects.

For simplicity, If you need to default to some value if nil you can use:

@something.nil? = "No" || "Yes"

If you're working from PowerShell, try the following as a single command.

PS MyRepo> git filter-branch --force --index-filter
>> "git rm --cached --ignore-unmatch -r .\\\path\\\to\\\directory"
>> --prune-empty --tag-name-filter cat -- --all

Then, git push --force --all.

This should do it:

ALTER TABLE test MODIFY locationExpert VARCHAR(120) 

If you are going to use the android icons, as described above ..

android:button="@android:drawable/..."

.. it's a nice option, but for this to work - I found you need to add toggle logic to show/hide the check mark, like this:

    checkBoxShowPwd.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        // checkbox status is changed from uncheck to checked.
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            int btnDrawable = android.R.drawable.checkbox_off_background;

            if (isChecked)
            {
                btnDrawable = android.R.drawable.checkbox_on_background;
            }

            checkBoxShowPwd.setButtonDrawable(btnDrawable);

        }
    });

To have a good follow-up about all this, Twitter - one of the pioneers of hashbang URL's and single-page-interface - admitted that the hashbang system was slow in the long run and that they have actually started reversing the decision and returning to old-school links.

Article about this is here.

Unfortunately, no. Not with HTML and CSS. You need an a element to make a link, and you can't wrap an entire table row in one.

The closest you can get is linking every table cell. Personally I'd just link one cell and use JavaScript to make the rest clickable. It's good to have at least one cell that really looks like a link, underlined and all, for clarity anyways.

Here's a simple jQuery snippet to make all table rows with links clickable (it looks for the first link and "clicks" it)

$("table").on("click", "tr", function(e) {
    if ($(e.target).is("a,input")) // anything else you don't want to trigger the click
        return;

    location.href = $(this).find("a").attr("href");
});

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

Demo

See the github repo, works with Django 3

A minimal Django file upload example

1. Create a django project

Run startproject::

$ django-admin.py startproject sample

now a folder(sample) is created.

2. create an app

Create an app::

$ cd sample
$ python manage.py startapp uploader

Now a folder(uploader) with these files are created::

uploader/
  __init__.py
  admin.py
  app.py
  models.py
  tests.py
  views.py
  migrations/
    __init__.py

3. Update settings.py

On sample/settings.py add 'uploader' to INSTALLED_APPS and add MEDIA_ROOT and MEDIA_URL, ie::

INSTALLED_APPS = [
    'uploader',
    ...<other apps>...      
]

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

4. Update urls.py

in sample/urls.py add::

...<other imports>...
from django.conf import settings
from django.conf.urls.static import static
from uploader import views as uploader_views

urlpatterns = [
    ...<other url patterns>...
    path('', uploader_views.UploadView.as_view(), name='fileupload'),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

5. Update models.py

update uploader/models.py::

from django.db import models
class Upload(models.Model):
    upload_file = models.FileField()    
    upload_date = models.DateTimeField(auto_now_add =True)

6. Update views.py

update uploader/views.py::

from django.views.generic.edit import CreateView
from django.urls import reverse_lazy
from .models import Upload
class UploadView(CreateView):
    model = Upload
    fields = ['upload_file', ]
    success_url = reverse_lazy('fileupload')
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['documents'] = Upload.objects.all()
        return context

7. create templates

Create a folder sample/uploader/templates/uploader

Create a file upload_form.html ie sample/uploader/templates/uploader/upload_form.html::

<div style="padding:40px;margin:40px;border:1px solid #ccc">
    <h1>Django File Upload</h1>
    <form method="post" enctype="multipart/form-data">
      {% csrf_token %}
      {{ form.as_p }}
      <button type="submit">Submit</button>
    </form><hr>
    <ul>
    {% for document in documents %}
        <li>
            <a href="{{ document.upload_file.url }}">{{ document.upload_file.name }}</a>
            <small>({{ document.upload_file.size|filesizeformat }}) - {{document.upload_date}}</small>
        </li>
    {% endfor %}
    </ul>
</div>

8. Syncronize database

Syncronize database and runserver::

$ python manage.py makemigrations
$ python manage.py migrate
$ python manage.py runserver

visit http://localhost:8000/

I don't see anything in here to suggest that this is a web-app but I have experienced this issue myself - I've got two xcopy commands on a post-build event and only one of them was failing. Something had a lock on the file, and it wasn't Visual Studio (as I tried restarting it.)

The only other thing that would have used the dll I built was IIS. And lo and behold,

A simple iisreset did the trick for me.

I recommand the following article : Hit Region Detection For HTML5 Canvas And How To Listen To Click Events On Canvas Shapes which goes through various situations.

However, it does not cover the addHitRegion API, which must be the best way (using math functions and/or comparisons is quite error prone). This approach is detailed on developer.mozilla

On load of My Windows Form the comboBox will display the ClassName column of my DataTable as it's the DisplayMember also has its ValueMember (not visible to user) with it.

private void Form1_Load(object sender, EventArgs e)
            {
                this.comboBoxSubjectCName.DataSource = this.Student.TableClass;
                this.comboBoxSubjectCName.DisplayMember = TableColumn.ClassName;//Column name that will be the DisplayMember
                this.comboBoxSubjectCName.ValueMember = TableColumn.ClassID;//Column name that will be the ValueMember
            }

You can also check your site's properties in IIS. (In IIS, right-click the site and choose Properties.) Make sure the Physical Path setting is pointing to the correct path for your application not some other application. (That fixed this error for me.)

I like to write a small plugin to make things cleaner:

$.fn.setClass = function(classes) {
    this.attr('class', classes);
    return this;
};

That way you can simply do

$('button').setClass('btn btn-primary');

In a new Php 5.6, you can use ... operator instead of using func_get_args().

So, using this, you can get all the parameters you pass:

function manyVars(...$params) {
   var_dump($params);
}

If youtube-dl is a terminal program, you can use the subprocess module to access the data you want.

Check out this link for more details: Calling an external command in Python

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

If for some reason you don't like interactive editors, you can use git rebase --onto.

Say you want to modify Commit1. First, branch from before Commit1:

git checkout -b amending [commit before Commit1]

Second, grab Commit1 with cherry-pick:

git cherry-pick Commit1

Now, amend your changes, creating Commit1':

git add ...
git commit --amend -m "new message for Commit1"

And finally, after having stashed any other changes, transplant the rest of your commits up to master on top of your new commit:

git rebase --onto amending Commit1 master

Read: "rebase, onto the branch amending, all commits between Commit1 (non-inclusive) and master (inclusive)". That is, Commit2 and Commit3, cutting the old Commit1 out entirely. You could just cherry-pick them, but this way is easier.

Remember to clean up your branches!

git branch -d amending

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.

In the Controller, you can use the javax.json to convert and manipulate this.

Download and add the .jar to the project libs and import the JsonObject.

To create an json object, you can use

JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();

To read it from String, you can use

JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();

Use single quotation marks ('):

var val = '@ViewBag.ForSection';
alert(val);

For me this was the default installation directory on Windows 7. Found it via Rusy's answer

I've had my drivers installed and the Arduino connected through an unpowered usb hub. Moving it to an USB port of my computer made it work.

Maybe I am answering very late. But I was also having a problem configuring host network in docker compose. Then I read the documentation thoroughly and made the changes and it worked. Please note this configuration is for docker-compose version "3.7". Here einwohner_net and elk_net_net are my user-defined networks required for my application. I am using host net to get some system metrics.

You can use the BIT field

To create new table:

CREATE TABLE Tb_Table1
(
ID              INT,
BitColumn       BIT DEFAULT 1
)

Adding Column in existing Table:

ALTER TABLE Tb_Table1 ADD BitColumn  BIT DEFAULT 1

To Insert record:

INSERT Tb_Table1 VALUES(11,0)

Normal assignment (=) is not possible inside a lambda expression, although it is possible to perform various tricks with setattr and friends.

Solving your problem, however, is actually quite simple:

input = [Object(name=""), Object(name="fake_name"), Object(name="")]
output = filter(
    lambda o, _seen=set():
        not (not o and o in _seen or _seen.add(o)),
    input
    )

which will give you

[Object(Object(name=''), name='fake_name')]

As you can see, it's keeping the first blank instance instead of the last. If you need the last instead, reverse the list going in to filter, and reverse the list coming out of filter:

output = filter(
    lambda o, _seen=set():
        not (not o and o in _seen or _seen.add(o)),
    input[::-1]
    )[::-1]

which will give you

[Object(name='fake_name'), Object(name='')]

One thing to be aware of: in order for this to work with arbitrary objects, those objects must properly implement __eq__ and __hash__ as explained here.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

You can do this with the code below, and the code in your question was actually very close to what you needed, all you have to do is call the cmap object you have.

import matplotlib

cmap = matplotlib.cm.get_cmap('Spectral')

rgba = cmap(0.5)
print(rgba) # (0.99807766255210428, 0.99923106502084169, 0.74602077638401709, 1.0)

For values outside of the range [0.0, 1.0] it will return the under and over colour (respectively). This, by default, is the minimum and maximum colour within the range (so 0.0 and 1.0). This default can be changed with cmap.set_under() and cmap.set_over().

For "special" numbers such as np.nan and np.inf the default is to use the 0.0 value, this can be changed using cmap.set_bad() similarly to under and over as above.

Finally it may be necessary for you to normalize your data such that it conforms to the range [0.0, 1.0]. This can be done using matplotlib.colors.Normalize simply as shown in the small example below where the arguments vmin and vmax describe what numbers should be mapped to 0.0 and 1.0 respectively.

import matplotlib

norm = matplotlib.colors.Normalize(vmin=10.0, vmax=20.0)

print(norm(15.0)) # 0.5

A logarithmic normaliser (matplotlib.colors.LogNorm) is also available for data ranges with a large range of values.

(Thanks to both Joe Kington and tcaswell for suggestions on how to improve the answer.)

For <input type=number>, by the HTML5 CR, the size attribute is not allowed. However, in Obsolete features it says: “Authors should not, but may despite requirements to the contrary elsewhere in this specification, specify the maxlength and size attributes on input elements whose type attributes are in the Number state. One valid reason for using these attributes regardless is to help legacy user agents that do not support input elements with type="number" to still render the text field with a useful width.”

Thus, the size attribute can be used, but it only affects older browsers that do not support type=number, so that the element falls back to a simple text control, <input type=text>.

The rationale behind this is that the browser is expected to provide a user interface that takes the other attributes into account, for good usability. As the implementations may vary, any size imposed by an author might mess things up. (This also applies to setting the width of the control in CSS.)

The conclusion is that you should use <input type=number> in a more or less fluid setup that does not make any assumptions about the dimensions of the element.

I had this error today and discovered it was an incorrectly-formatted year...

select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')

Notice the year has only three 'y's. It should have 4.

Double-check your format.

As explained by Scott Meyers in Effective Modern C++,

Calls to std::type_info::name are not guaranteed to return anythong sensible.

The best solution is to let the compiler generate an error message during the type deduction, for example,

template<typename T>
class TD;

int main(){
    const int theAnswer = 32;
    auto x = theAnswer;
    auto y = &theAnswer;
    TD<decltype(x)> xType;
    TD<decltype(y)> yType;
    return 0;
}

The result will be something like this, depending on the compilers,

test4.cpp:10:21: error: aggregate ‘TD<int> xType’ has incomplete type and cannot be defined TD<decltype(x)> xType;

test4.cpp:11:21: error: aggregate ‘TD<const int *> yType’ has incomplete type and cannot be defined TD<decltype(y)> yType;

Hence, we get to know that x's type is int, y's type is const int*

You can float the elements (the map wrapper, and the paragraph), or use inline-block on both of them.

You can do:

struct employee_s {
  int id;
  char* name;
} employee_default = {0, "none"};

typedef struct employee_s employee;

And then you just have to remember to do the default initialization when you declare a new employee variable:

employee foo = employee_default;

Alternatively, you can just always build your employee struct via a factory function.

For anyone else who runs into this...

Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.

Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:

<div class="input-group" data-datepicker="true">
    <input name="date" type="text" class="form-control" />
    <span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>

It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).

$('*[data-datepicker="true"] input[type="text"]').datepicker({
    todayBtn: true,
    orientation: "top left",
    autoclose: true,
    todayHighlight: true
});

Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).

$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
    $('input[type="text"]', $(this).parent()).focus();
});

NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

To build upon Unknown's example, the Python equivalent of the function normdist() implemented in a lot of libraries would be:

def normcdf(x, mu, sigma):
    t = x-mu;
    y = 0.5*erfcc(-t/(sigma*sqrt(2.0)));
    if y>1.0:
        y = 1.0;
    return y

def normpdf(x, mu, sigma):
    u = (x-mu)/abs(sigma)
    y = (1/(sqrt(2*pi)*abs(sigma)))*exp(-u*u/2)
    return y

def normdist(x, mu, sigma, f):
    if f:
        y = normcdf(x,mu,sigma)
    else:
        y = normpdf(x,mu,sigma)
    return y

To anyone else who tried most of the solutions and still having problems.

My solution is different from the others, which is located at the bottom of this post, but before you try it make sure you have exhausted the following lists. To be sure, I have tried all of them but to no avail.

1. Recompile and redeploy from scratch, don't update the existing app. SO Answer

2. Grant IIS_IUSRS full access to the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files"

   Keep in mind the framework version you are using. If your app is using impersonation, use that identity instead of IIS_IUSRS

3. Delete all contents of the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files".

   Keep in mind the framework version you are using

4. Change the identity of the AppPool that your app is using, from ApplicatonPoolIdentity to NetworkService.

   IIS > Application Pools > Select current app pool > Advance Settings > Identity.

   SO Answer (please restore to default if it doesn't work)

5. Verify IIS Version and AppPool .NET version compatibility with your app. Highly applicable to first time deployments. SO Answer

6. Verify impersonation configuration if applicable. SO Answer

My Solution:

I found out that certain anti-virus softwares are actively blocking compilations of DLLs within the directory "Temporary ASP.NET Files", mine was McAfee, the IT people failed to notify me of the installation.

As per advice by both McAfee experts and Microsoft, you need to exclude the directory "Temporary ASP.NET Files" in the real time scanning.

Sources:

• McAfee Support Forum
• Microsoft Support
• Asp.Net Forum

Don't disable the Anti-Virus because it is only doing its job. Don't manually copy missing DLL files in the directory \Temporary ASP.NET Files{project name} because thats duct taping.

This was my own attempt, but I'll use the answer by annakata as it seems much cleaner:

function AddUrlParameter(sourceUrl, parameterName, parameterValue, replaceDuplicates)
{
    if ((sourceUrl == null) || (sourceUrl.length == 0)) sourceUrl = document.location.href;
    var urlParts = sourceUrl.split("?");
    var newQueryString = "";
    if (urlParts.length > 1)
    {
        var parameters = urlParts[1].split("&");
        for (var i=0; (i < parameters.length); i++)
        {
            var parameterParts = parameters[i].split("=");
            if (!(replaceDuplicates && parameterParts[0] == parameterName))
            {
                if (newQueryString == "")
                    newQueryString = "?";
                else
                    newQueryString += "&";
                newQueryString += parameterParts[0] + "=" + parameterParts[1];
            }
        }
    }
    if (newQueryString == "")
        newQueryString = "?";
    else
        newQueryString += "&";
    newQueryString += parameterName + "=" + parameterValue;

    return urlParts[0] + newQueryString;
}

Also, I found this jQuery plugin from another post on stackoverflow, and if you need more flexibility you could use that: http://plugins.jquery.com/project/query-object

I would think the code would be (haven't tested):

return $.query.parse(sourceUrl).set(parameterName, parameterValue).toString();

Use COUNT in a SELECT query.

$result = mysql_query('SELECT COUNT(1) FROM table');
$num_rows = mysql_result($result, 0, 0);

I needed an inline vertical line, so I tricked a button into becoming a line.

<button type="button" class="v_line">l</button>

.v_line {
         width: 0px;
         padding: .5em .5px;
         background-color: black;
         margin: 0px; 4px;
        }

from Jackson 2.7.x+ there is a way to annotate the member variable itself:

 @JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY)
 private List<String> newsletters;

More info here: Jackson @JsonFormat

You can try this:

mean(as.matrix(cluster1))

There's a better way to handle it using Native MongoDB code in Mongoose.

exports.getUsers = function(req, res, next) {

    var usersProjection = { 
        __v: false,
        _id: false
    };

    User.find({}, usersProjection, function (err, users) {
        if (err) return next(err);
        res.json(users);
    });    
}

http://docs.mongodb.org/manual/reference/method/db.collection.find/

Note:

var usersProjection

The list of objects listed here will not be returned / printed.

encoding this line fixed it for me.

m.update(line.encode('utf-8'))

For the Mac terminal:

script -a -t 0 out.txt screen /dev/ttyUSB0 115200

Details

• script: A built-in application to "make a typescript of terminal session"
• -a: Append to output file
• -t 0: Time between writing to output file is 0 seconds, so out.txt is updated for every new character
• out.txt: Is just the output file name
• screen /dev/ttyUSB0 115200: Command from question for connecting to an external device

You can then use tail to see that the file is updating.

tail -100 out.txt

One more idea for anyone else getting this...

I had some gzipped svg, but it had a php error in the output, which caused this error message. (Because there was text in the middle of gzip binary.) Fixing the php error solved it.

You use List#get(int index) to get an object with the index index in the list. You use it like that:

List<ExampleClass> list = new ArrayList<ExampleClass>();
list.add(new ExampleClass());
list.add(new ExampleClass());
list.add(new ExampleClass());
ExampleClass exampleObj = list.get(2); // will get the 3rd element in the list (index 2);

try

private View myFragmentView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{
myFragmentView = inflater.inflate(R.layout.myLayoutId, container, false);
myView = myFragmentView.findViewById(R.id.myIdTag)
return myFragmentView;
}

Select's default value should be one of its value in the list. In order to load the select with default value you can use ng-options. A scope variable need to be set in the controller and that variable is assigned as ng-model in HTML's select tag.

The question has already been marked as answered, But I guess the question states that the person wants to remove multiple columns from a DataTable.

So for that, here is what I did, when I came across the same problem.

string[] ColumnsToBeDeleted = { "col1", "col2", "col3", "col4" };

foreach (string ColName in ColumnsToBeDeleted)
{
    if (dt.Columns.Contains(ColName))
        dt.Columns.Remove(ColName);
}

My way to do it

$('#table_1').DataTable({
    processing: true,
    serverSide: true,
    ajax: 'customer/data',
    columns: [
        { data: 'id', name: 'id' , width: '50px', class: 'text-right' },
        { data: 'name', name: 'name' width: '50px', class: 'text-right' }
    ]
});

In my case it helped to remove node_modules and package-lock.json.

After that just reinstall everything with npm install.

Use this way so that result will not be displayed while running stored procedure.

The query:

SELECT a.strUserID FROM tblUsers a WHERE a.lngUserID = lngUserID LIMIT 1 INTO @strUserID;

There are some cases where you can use the e.message or e.messages.. But it does not work in all cases. Anyway the more safe is to use the str(e)

try:
  ...
except Exception as e:
  print(e.message)

^ outside of the character class ("[a-zA-Z]") notes that it is the "begins with" operator.
^ inside of the character negates the specified class.

So, "^[a-zA-Z]" translates to "begins with character from a-z or A-Z", and "[^a-zA-Z]" translates to "is not either a-z or A-Z"

Here's a quick reference: http://www.regular-expressions.info/reference.html

You want to enclose it with a scrollView.

This can happen if you forget to return a value from a function: it then returns None. Look at all places where you are assigning to that variable, and see if one of them is a function call where the function lacks a return statement.

Use Array's sort() method, eg

myArray.sort(function(a, b) {
    return a.distance - b.distance;
});

Use LIKE ANY(ARRAY['AAA%', 'BBB%', 'CCC%']) as per this cool trick @maniek showed earlier today.

Google has added a new feature since the last answer was posted here. You can now add the controlList attribute as shown here:

<video width="512" height="380" controls controlsList="nodownload">
    <source data-src="mov_bbb.ogg" type="video/mp4">
</video>

You can find all options of the controllist attribute here:

As stated in this answer not all browsers support the standard way. It is not a good idea to use for robust user experience. And if you use it, you cannot ask too much.

Instead use time-picker libraries. For example: TimePicker.js is a zero dependency and lightweight library. Use it like:

var timepicker = new TimePicker('time', {_x000D_
  lang: 'en',_x000D_
  theme: 'dark'_x000D_
});_x000D_
timepicker.on('change', function(evt) {_x000D_
  _x000D_
  var value = (evt.hour || '00') + ':' + (evt.minute || '00');_x000D_
  evt.element.value = value;_x000D_
_x000D_
});

<script src="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.js"></script>_x000D_
<link href="https://cdn.jsdelivr.net/timepicker.js/latest/timepicker.min.css" rel="stylesheet"/>_x000D_
_x000D_
<div>_x000D_
  <input type="text" id="time" placeholder="Time">_x000D_
</div>

Your code is very vague and not understandable, but I can provide you with an alternative.

First of all, if you want temp to go through the whole string, you can do something like this:

char *temp;
for (temp = your_string; *temp; ++temp)
    /* do something with *temp */

The term *temp as the for condition simply checks whether you have reached the end of the string or not. If you have, *temp will be '\0' (NUL) and the for ends.

Now, inside the for, you want to find the bits that compose *temp. Let's say we print the bits:

for (as above)
{
    int bit_index;
    for (bit_index = 7; bit_index >= 0; --bit_index)
    {
        int bit = *temp >> bit_index & 1;
        printf("%d", bit);
    }
    printf("\n");
}

To make it a bit more generic, that is to convert any type to bits, you can change the bit_index = 7 to bit_index = sizeof(*temp)*8-1

SortedSet and Comparator. Comparator should honour the id field.

Thank you guys for the help,

When I asked at first I didn't think it's even possible, but after your answers I googled and found this amazing tutorial:

http://blog.thomaslebrun.net/2011/11/html-5-how-to-customize-the-error-message-for-a-required-field/#.UsNN1BYrh2M

for multiple databases:

mysqldump -u user -p --ignore-table=db1.tbl1 --ignore-table=db2.tbl1 --databases db1 db2 ..

The use of fork and exec exemplifies the spirit of UNIX in that it provides a very simple way to start new processes.

The fork call basically makes a duplicate of the current process, identical in almost every way. Not everything is copied over (for example, resource limits in some implementations) but the idea is to create as close a copy as possible.

The new process (child) gets a different process ID (PID) and has the PID of the old process (parent) as its parent PID (PPID). Because the two processes are now running exactly the same code, they can tell which is which by the return code of fork - the child gets 0, the parent gets the PID of the child. This is all, of course, assuming the fork call works - if not, no child is created and the parent gets an error code.

The exec call is a way to basically replace the entire current process with a new program. It loads the program into the current process space and runs it from the entry point.

So, fork and exec are often used in sequence to get a new program running as a child of a current process. Shells typically do this whenever you try to run a program like find - the shell forks, then the child loads the find program into memory, setting up all command line arguments, standard I/O and so forth.

But they're not required to be used together. It's perfectly acceptable for a program to fork itself without execing if, for example, the program contains both parent and child code (you need to be careful what you do, each implementation may have restrictions). This was used quite a lot (and still is) for daemons which simply listen on a TCP port and fork a copy of themselves to process a specific request while the parent goes back to listening.

Similarly, programs that know they're finished and just want to run another program don't need to fork, exec and then wait for the child. They can just load the child directly into their process space.

Some UNIX implementations have an optimized fork which uses what they call copy-on-write. This is a trick to delay the copying of the process space in fork until the program attempts to change something in that space. This is useful for those programs using only fork and not exec in that they don't have to copy an entire process space.

If the exec is called following fork (and this is what happens mostly), that causes a write to the process space and it is then copied for the child process.

Note that there is a whole family of exec calls (execl, execle, execve and so on) but exec in context here means any of them.

The following diagram illustrates the typical fork/exec operation where the bash shell is used to list a directory with the ls command:

+--------+
| pid=7  |
| ppid=4 |
| bash   |
+--------+
    |
    | calls fork
    V
+--------+             +--------+
| pid=7  |    forks    | pid=22 |
| ppid=4 | ----------> | ppid=7 |
| bash   |             | bash   |
+--------+             +--------+
    |                      |
    | waits for pid 22     | calls exec to run ls
    |                      V
    |                  +--------+
    |                  | pid=22 |
    |                  | ppid=7 |
    |                  | ls     |
    V                  +--------+
+--------+                 |
| pid=7  |                 | exits
| ppid=4 | <---------------+
| bash   |
+--------+
    |
    | continues

The steps I needed to perform were:

1. Add reference to System.Web.Http.WebHost.
2. Add App_Start\WebApiConfig.cs (see code snippet below).
3. Import namespace System.Web.Http in Global.asax.cs.
4. Call WebApiConfig.Register(GlobalConfiguration.Configuration) in MvcApplication.Application_Start() (in file Global.asax.cs), before registering the default Web Application route as that would otherwise take precedence.
5. Add a controller deriving from System.Web.Http.ApiController.

I could then learn enough from the tutorial (Your First ASP.NET Web API) to define my API controller.

App_Start\WebApiConfig.cs:

using System.Web.Http;

class WebApiConfig
{
    public static void Register(HttpConfiguration configuration)
    {
        configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
            new { id = RouteParameter.Optional });
    }
}

Global.asax.cs:

using System.Web.Http;

...

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterGlobalFilters(GlobalFilters.Filters);
    WebApiConfig.Register(GlobalConfiguration.Configuration);
    RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Update 10.16.2015:

Word has it, the NuGet package Microsoft.AspNet.WebApi must be installed for the above to work.

Assuming the items override ToString appropriately:

public void WriteToConsole(IEnumerable items)
{
    foreach (object o in items)
    {
        Console.WriteLine(o);
    }
}

(There'd be no advantage in using generics in this loop - we'd end up calling Console.WriteLine(object) anyway, so it would still box just as it does in the foreach part in this case.)

EDIT: The answers using List<T>.ForEach are very good.

My loop above is more flexible in the case where you have an arbitrary sequence (e.g. as the result of a LINQ expression), but if you definitely have a List<T> I'd say that List<T>.ForEach is a better option.

One advantage of List<T>.ForEach is that if you have a concrete list type, it will use the most appropriate overload. For example:

List<int> integers = new List<int> { 1, 2, 3 };
List<string> strings = new List<string> { "a", "b", "c" };

integers.ForEach(Console.WriteLine);
strings.ForEach(Console.WriteLine);

When writing out the integers, this will use Console.WriteLine(int), whereas when writing out the strings it will use Console.WriteLine(string). If no specific overload is available (or if you're just using a generic List<T> and the compiler doesn't know what T is) it will use Console.WriteLine(object).

Note the use of Console.WriteLine as a method group, by the way. This is more concise than using a lambda expression, and actually slightly more efficient (as the delegate will just be a call to Console.WriteLine, rather than a call to a method which in turn just calls Console.WriteLine).

In my case I added dependency via Nuget:

Microsoft.EntityFrameworkCore.Tools

And then run via Package Manager Console:

add-migration Initial -Context "ContextName" -StartupProject "EntryProject.Name" -Project "MigrationProject.Name"

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

Specific Solution to the example problem:-

Try [A-Z]*123$ will match 123, AAA123, ASDFRRF123. In case you need at least a character before 123 use [A-Z]+123$.

General Solution to the question (How to match "any character" in the regular expression):

1. If you are looking for anything including whitespace you can try [\w|\W]{min_char_to_match,}.
2. If you are trying to match anything except whitespace you can try [\S]{min_char_to_match,}.

I should be able to accomplish this through standard java string manipulation, nothing Android or TextView specific.

Something like:

String upperString = myString.substring(0, 1).toUpperCase() + myString.substring(1).toLowerCase();

Although there are probably a million ways to accomplish this. See String documentation.

EDITED I added the .toLowerCase()

i received this message for an application on iis 7.5 with a classic app pool assigned to .net 2.0. i needed to go to Handler Mappings and add two script maps, both were the same with except for the name. one name was svc-ISAPI-2.0-64, the other was svc-ISAPI-2.0. The request path was .svc. And the Executable was %SystemRoot%\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll. i restarted iis and all was happy

The only thing that worked for me was the accepted answer of

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML('<?xml encoding="utf-8" ?>' . $profile);
echo $dom->saveHTML();

HOWEVER

This brought about new issues, of having <?xml encoding="utf-8" ?> in the output of the document.

The solution for me was then to do

foreach ($doc->childNodes as $xx) {
    if ($xx instanceof \DOMProcessingInstruction) {
        $xx->parentNode->removeChild($xx);
    }
}

Some solutions told me that to remove the xml header, that I had to perform

$dom->saveXML($dom->documentElement);

This didn't work for me as for a partial document (e.g. a doc with two <p> tags), only one of the <p> tags where being returned.

According to the php manual you can do this in two ways. It depends what you need to check.

If you want to check if the given key or index exists in the array use array_key_exists

<?php
$search_array = array('first' => 1, 'second' => 4);
if (array_key_exists('first', $search_array)) {
echo "The 'first' element is in the array";
 }
?>

If you want to check if a value exists in an array use in_array

 <?php
 $os = array("Mac", "NT", "Irix", "Linux");
if (in_array("Irix", $os)) {
echo "Got Irix";
}
?>

#hero { width:100%;height:100%;background:url('{$img_ps_dir}cms/how-it-works/hero.jpg') no-repeat top center; }
.videoWrapper { position:relative;padding-bottom:56.25%;padding-top:25px;max-width:100%; }

<div id="hero">
    <div class="container">
        <div class="row-fluid">
            <script src="https://www.youtube.com/iframe_api"></script>
            <center>
            <div class="videoWrapper">
                 <div id="player"></div>
            </div>
            </center>
            <script>
            function onYouTubeIframeAPIReady() { 
                player = new YT.Player('player', {
                   videoId:'xxxxxxxxxxx',playerVars: {  controls:0,autoplay:0,disablekb:1,enablejsapi:1,iv_load_policy:3,modestbranding:1,showinfo:0,rel:0,theme:'light' }
                } );
                resizeHeroVideo();
             }
             </script>
        </div>
    </div>
</div>

var player = null;
$( document ).ready(function() {
    resizeHeroVideo();
} );

$(window).resize(function() {
    resizeHeroVideo();
});

function resizeHeroVideo() {
    var content = $('#hero');
    var contentH = viewportSize.getHeight();
    contentH -= 158;
    content.css('height',contentH);

    if(player != null) {
        var iframe = $('.videoWrapper iframe');
        var iframeH = contentH - 150;
        if (isMobile) {
            iframeH = 163; 
        }
        iframe.css('height',iframeH);
        var iframeW = iframeH/9 * 16;
        iframe.css('width',iframeW);
    }
}

resizeHeroVideo is called only after the Youtube player has fully loaded (on page load does not work), and whenever the browser window is resized. When it runs, it calculates the height and width of the iframe and assigns the appropriate values maintaining the correct aspect ratio. This works whether the window is resized horizontally or vertically.

By this way we can send data with http post method and get result

If you have date as a datetime.datetime (or a datetime.date) instance and want to combine it via a time from a datetime.time instance, then you can use the classmethod datetime.datetime.combine:

import datetime
dt = datetime.datetime(2020, 7, 1)
t = datetime.time(12, 34)
combined = datetime.datetime.combine(dt.date(), t)

Instead of saying:

if [ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]; then

say:

if [[ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]]; then

You might also want to refer to Conditional Constructs.

Try this:

paramstr.Remove((paramstr.Length-1),1);

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

When upgrading angular to 1.3 and above I found an issue using Jacek Ciolek's great answer:

• Add data to the reference field
• Add the same data to the field with the directive on it (this field is now valid)
• Go back to the reference field and change the data (directive field remains valid)

I tested rdukeshier's answer (updating var modelToMatch = element.attr('sameAs') to var modelToMatch = attrs.sameAs to retrieve the reference model correctly) but the same issue occurred.

To fix this (tested in angular 1.3 and 1.4) I adapted rdukeshier's code and added a watcher on the reference field to run all validations when the reference field is changed. The directive now looks like this:

angular.module('app', [])
  .directive('sameAs', function () {
    return {
      require: 'ngModel',
      link: function(scope, element, attrs, ctrl) {
        var modelToMatch = attrs.sameAs;      

        scope.$watch(attrs.sameAs, function() {
          ctrl.$validate();          
        })

        ctrl.$validators.match = function(modelValue, viewValue) {
          return viewValue === scope.$eval(modelToMatch);
        };
      }
   };
});

Updated codepen

If you need just logical value (as it almost always is), the following one-liner will help you:

boolean ifIntsEqual = !((Math.max(a,b) - Math.min(a, b)) > 0);

And it works even in Java 1.5+, maybe even in 1.1 (i don't have one). Please tell us, if you can test it in 1.5-.

This one will do too:

boolean ifIntsEqual = !((Math.abs(a-b)) > 0);

Have You tried BeautifulSoup ?

from bs4 import BeautifulSoup
soup = BeautifulSoup('<div id="remository">20</div>')
tag=soup.div
print(tag.string)

This gives You 20 on output.

Suppose you have below String.

Our Deluxe cabins are warm, cozy & comfortable

var str = $("p").text(); // get the text from <p> tag
$('p').html(str).text();  // Now,decode html entities in your variable i.e 

str and assign back to

tag.

that's it.

ASP.NET Core 2.0 with Angular

https://fullstackmark.com/post/13/jwt-authentication-with-aspnet-core-2-web-api-angular-5-net-core-identity-and-facebook-login

Make sure to use type of authentication filter

[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]

the simplest way is

$("body").html(data);

Hello Try this code below

public class RemoveCharacter {

    public static void main(String[] args){
        String str = "MXy nameX iXs farXazX";
        char x = 'X';
        System.out.println(removeChr(str,x));
    }

    public static String removeChr(String str, char x){
        StringBuilder strBuilder = new StringBuilder();
        char[] rmString = str.toCharArray();
        for(int i=0; i<rmString.length; i++){
            if(rmString[i] == x){

            } else {
                strBuilder.append(rmString[i]);
            }
        }
        return strBuilder.toString();
    }
}

You should use raw_input to take a string input. then use islower method of str object.

s = raw_input('Type a word')
l = []
for c in s.strip():
    if c.islower():
        print c
        l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)

Just do -

dir(s)

and you will find islower and other attributes of str

Here is a more concise way to achieve the "less insecure" method proposed by CoolAJ86

request({
  url: url,
  agentOptions: {
    rejectUnauthorized: false
  }
}, function (err, resp, body) {
  // ...
});

tag_story.splice(tag_story.indexOf(id_tag), 1);

1. set the classpath and compile

   javac -classpath "C:\Program Files\Java\jdk1.6.0_updateVersion\tools.jar" yourApp.java

2. create manifest.txt

   Main-Class: yourApp newline

3. create yourApp.jar

   jar cvf0m yourApp.jar manifest.txt yourApp.class

4. run yourApp.jar

   java -jar yourApp.jar

=if([Logical Test 1],[Action 1],if([Logical Test 2],[Action 1],if([Logical Test 3],[Action 3],[Value if all logical tests return false])))

Replace the components in the square brackets as necessary.

Along the same lines as previous answers, but a very short addition that Allows to use all Control properties without having cross thread invokation exception.

Helper Method

    /// <summary>
    /// Helper method to determin if invoke required, if so will rerun method on correct thread.
    /// if not do nothing.
    /// </summary>
    /// <param name="c">Control that might require invoking</param>
    /// <param name="a">action to preform on control thread if so.</param>
    /// <returns>true if invoke required</returns>
    public bool ControlInvokeRequired(Control c,Action a)
    {
        if (c.InvokeRequired) c.Invoke(new MethodInvoker(delegate { a(); }));
        else return false;

        return true;
    }

Sample Usage

    // usage on textbox
    public void UpdateTextBox1(String text)
    {
        //Check if invoke requied if so return - as i will be recalled in correct thread
        if (ControlInvokeRequired(textBox1, () => UpdateTextBox1(text))) return;
        textBox1.Text = ellapsed;
    }

    //Or any control
    public void UpdateControl(Color c,String s)
    {
        //Check if invoke requied if so return - as i will be recalled in correct thread
        if (ControlInvokeRequired(myControl, () => UpdateControl(c,s))) return;
        myControl.Text = s;
        myControl.BackColor = c;
    }

        DBStats = False  
End Function

So "myBase" is a Database Object, I have made a class to access to database (class with insert, update etc...) and on the module the class is use declare in an object (obviously) and I can test the connection with "[the Object].DBStats":

Dim BaseAccess As New myClass
BaseAccess.DBOpen 'I open connection
Debug.Print BaseAccess.DBStats ' I test and that tell me true
BaseAccess.DBClose ' I close the connection
Debug.Print BaseAccess.DBStats ' I test and tell me false

Edit : In DBOpen I use "OpenDatabase" and in DBClose I use ".Close" and "set myBase = nothing" Edit 2: In the function, if you are not connect, .version give you an error so if aren't connect, the errorHandler give you false

New Updates for iOS Device Support file. Don't need to update Xcode.

You just need to add support file to Xcode's DeviceSupport folder.

iOS 11.3 Developer Disk Image

Extract the zip and then copy folder.

Paste this folder in this path

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

Quit the Xcode and restart, it will work.

You want to use DATEADD, using a negative duration. e.g.

DATEADD(minute, -15, '2000-01-01 08:30:00') 

Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. From the keyboard, it would be CTRL-K.

I don't believe anyone would have a reason to use it any more. Most forms are generated in a printer control language like postscript.

@Talvi Wilson noted it used in python '\v'.

print("hello\vworld")

Output:

hello
     world

The above output appears to result in the default vertical size being one line. I have tested with perl "\013" and the same output occurs. This could be used to do line feed without a carriage return on devices with convert linefeed to carriage-return + linefeed.

This might be too late for your work, but here is how I did it. I want something run everyday at 1AM - I believe this is similar to what you are doing. Here is how I did it:

CREATE EVENT event_name
  ON SCHEDULE
    EVERY 1 DAY
    STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL 1 HOUR)
  DO
    # Your awesome query

Django has support for this, check get_or_create

person, created = Person.objects.get_or_create(name='abc')
if created:
    # A new person object created
else:
    # person object already exists

I also faced the same problem.I resolved by doing the build by following steps as.

-->Right click on the project select RunAs ->Run configurations

Select your project as BaseDirectory. In place of goals give eclipse:eclipse install

-->In the second tab give -Xmx1024m as VM arguments.

TryParse and the Exception Tax

Parse throws an exception if the conversion from a string to the specified datatype fails, whereas TryParse explicitly avoids throwing an exception.

One nice feature of the Immediate Window in Visual Studio is its ability to evaluate the return value of a method particularly if it is called by your client code but it is not part of a variable assignment. In Debug mode, as mentioned, you can interact with variables and execute expressions in memory which plays an important role in being able to do this.

For example, if you had a static method that returns the sum of two numbers such as:

private static int GetSum(int a, int b)
{
    return a + b;
}

Then in the Immediate Window you can type the following:

? GetSum(2, 4)
6

As you can seen, this works really well for static methods. However, if the method is non-static then you need to interact with a reference to the object the method belongs to.

For example, let’s say this is what your class looks like:

private class Foo
{
    public string GetMessage()
    {
        return "hello";
    }
}

If the object already exists in memory and it’s in scope, then you can call it in the Immediate Window as long as it has been instantiated before your current breakpoint (or, at least, before wherever the code is paused in debug mode):

? foo.GetMessage(); // object ‘foo’ already exists
"hello"

In addition, if you want to interact and test the method directly without relying on an existing instance in memory, then you can instantiate your own instance in the Immediate Window:

? Foo foo = new Foo(); // new instance of ‘Foo’
{temp.Program.Foo}
? foo.GetMessage()
"hello"

You can take it a step further and temporarily assign the method's results to variables if you want to do further evaluations, calculations, etc.:

? string msg = foo.GetMessage();
"hello"
? msg + " there!"
"hello there!"

Furthermore, if you don’t even want to declare a variable name for a new object and just want to run one of its methods/functions then do this:

? new Foo().GetMessage()
"hello" 

A very common way to see the value of a method is to select the method name of a class and do a ‘Add Watch’ so that you can see its current value in the Watch window. However, once again, the object needs to be instantiated and in scope for a valid value to be displayed. This is much less powerful and more restrictive than using the Immediate Window.

Along with inspecting methods, you can do simple math equations:

? 5 * 6
30

or compare values:

? 5==6
false
? 6==6
true

The question mark ('?') is unnecessary if you are in directly in the Immediate Window but it is included here for clarity (to distinguish between the typed in expressions versus the results.) However, if you are in the Command Window and need to do some quick stuff in the Immediate Window then precede your statements with '?' and off you go.

Intellisense works in the Immediate Window, but it sometimes can be a bit inconsistent. In my experience, it seems to be only available in Debug mode, but not in design, non-debug mode.

Unfortunately, another drawback of the Immediate Window is that it does not support loops.

    this.toolStrip1 = new System.Windows.Forms.ToolStrip();
    this.toolStrip1.Location = new System.Drawing.Point(0, 0);
    this.toolStrip1.Name = "toolStrip1";
    this.toolStrip1.Size = new System.Drawing.Size(444, 25);
    this.toolStrip1.TabIndex = 0;
    this.toolStrip1.Text = "toolStrip1";
    object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

    ToolStripButton btn = new ToolStripButton("m1");
    btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
    btn.Image = (Image)O;
    this.toolStrip1.Items.Add(btn);

    this.Controls.Add(this.toolStrip1);

You can check this way too

<c:if test="${theBooleanVariable ne true}">It's false!</c:if>

wxLua has three sleep functions:

local wx = require 'wx'
wx.wxSleep(12)   -- sleeps for 12 seconds
wx.wxMilliSleep(1200)   -- sleeps for 1200 milliseconds
wx.wxMicroSleep(1200)   -- sleeps for 1200 microseconds (if the system supports such resolution)

You can use Internet Explorer to browse folders and files together in tree. It is a file explorer in Favorites Window. You just need replace "favorites folder" to folder which you want see as a root folder

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

You may as well use for x in values rather than for x in values[:]; the latter makes an unnecessary copy. Also, of course that code checks for a length of 2 rather than of 3...

The code only prints one item per value of x - and x is iterating over the elements of values, which are the sublists. So it will only print each sublist once.

ensure_ascii=False really only defers the issue to the decoding stage:

>>> dict2 = {'LeafTemps': '\xff\xff\xff\xff',}
>>> json1 = json.dumps(dict2, ensure_ascii=False)
>>> print(json1)
{"LeafTemps": "????"}
>>> json.loads(json1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 328, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 381, in raw_decode
    obj, end = self.scan_once(s, idx)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte

Ultimately you can't store raw bytes in a JSON document, so you'll want to use some means of unambiguously encoding a sequence of arbitrary bytes as an ASCII string - such as base64.

>>> import json
>>> from base64 import b64encode, b64decode
>>> my_dict = {'LeafTemps': '\xff\xff\xff\xff',} 
>>> my_dict['LeafTemps'] = b64encode(my_dict['LeafTemps'])
>>> json.dumps(my_dict)
'{"LeafTemps": "/////w=="}'
>>> json.loads(json.dumps(my_dict))
{u'LeafTemps': u'/////w=='}
>>> new_dict = json.loads(json.dumps(my_dict))
>>> new_dict['LeafTemps'] = b64decode(new_dict['LeafTemps'])
>>> print new_dict
{u'LeafTemps': '\xff\xff\xff\xff'}

I came across this question when I was trying similar things.

It's a good idea to apply a recursive definition, as in Vadim Smolyakov's answer, combined with a DP (dynamic programming), but for the latter you may apply the lru_cache decorator from module functools:

import functools

@functools.lru_cache(maxsize = None)
def binom(n,k):
    if k == 0: return 1
    if n == k: return 1
    return binom(n-1,k-1)+binom(n-1,k)

By default, the classes in the csv module use Windows-style line terminators (\r\n) rather than Unix-style (\n). Could this be what’s causing the apparent double line breaks?

If so, you can override it in the DictWriter constructor:

output = csv.DictWriter(open('file3.csv','w'), delimiter=',', lineterminator='\n', fieldnames=headers)

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

A linear search works by looking at each element in a list of data until it either finds the target or reaches the end. This results in O(n) performance on a given list. A binary search comes with the prerequisite that the data must be sorted. We can leverage this information to decrease the number of items we need to look at to find our target. We know that if we look at a random item in the data (let's say the middle item) and that item is greater than our target, then all items to the right of that item will also be greater than our target. This means that we only need to look at the left part of the data. Basically, each time we search for the target and miss, we can eliminate half of the remaining items. This gives us a nice O(log n) time complexity.

Just remember that sorting data, even with the most efficient algorithm, will always be slower than a linear search (the fastest sorting algorithms are O(n * log n)). So you should never sort data just to perform a single binary search later on. But if you will be performing many searches (say at least O(log n) searches), it may be worthwhile to sort the data so that you can perform binary searches. You might also consider other data structures such as a hash table in such situations.

Are you committed to using the Inner join syntax?

If not you could use this alternative syntax:

SELECT * 
FROM Y,X
WHERE (X.QID=Y.QID) or (X.QUID is null and Y.QUID is null)

If you don't want to change to numeric you can try this.

> as.vector(t(df)[,1])
[1] 1.0 2.0 2.6

$('#txtConfirmPassword').keyup(function(){


if($(this).val() != $('#txtNewPassword').val().substr(0,$(this).val().length))
{
 alert('confirm password not match');
}



});

in the folder where the build.xml resides run command only -

ant

and not the command - `

ant build.xml

`

. if you are using the ant file as build xml then the below steps helps you Steps : open cmd Prompt >> switch to the project location >>type ant and click enter key

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

check this out :)

var traingIds = "[1,2]";  // ${triningIdArray} this value getting from server 
alert(traingIds);  // alerts [1,2]
var type = typeof(traingIds);
alert(type);   // // alerts String

//remove square brackets
traingIds = traingIds.replace('[','');
traingIds = traingIds.replace(']','');
alert(traingIds);  // alerts 1,2        
var trainindIdArray = traingIds.split(',');

?for(i = 0; i< trainindIdArray.length; i++){
    alert(trainindIdArray[i]); //outputs individual numbers in array
    }? 

In plain English:

1. They are all source control as we all know.
2. In an analogy, if Git is a standalone computer, then GitHub is a network of computers connected by web with bells and whistlers.
3. So unless you open a GitHub acct and specifically tell VSC or any editor to use GitHub, you'll see your source code up-there otherwise they are only down here, - your local machine.

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

You can do joins as well using Hadley Wickham's awesome dplyr package.

library(dplyr)

#make sure that CustomerId cols are both type numeric
#they ARE not using the provided code in question and dplyr will complain
df1$CustomerId <- as.numeric(df1$CustomerId)
df2$CustomerId <- as.numeric(df2$CustomerId)

Mutating joins: add columns to df1 using matches in df2

#inner
inner_join(df1, df2)

#left outer
left_join(df1, df2)

#right outer
right_join(df1, df2)

#alternate right outer
left_join(df2, df1)

#full join
full_join(df1, df2)

Filtering joins: filter out rows in df1, don't modify columns

semi_join(df1, df2) #keep only observations in df1 that match in df2.
anti_join(df1, df2) #drops all observations in df1 that match in df2.

You can use jstat, like :

 jstat -gc pid

I've found this answer in the site https://plainjs.com/javascript/styles/set-and-get-css-styles-of-elements-53/.

In this code we add multiple styles in an element:

let_x000D_
    element = document.querySelector('span')_x000D_
  , cssStyle = (el, styles) => {_x000D_
      for (var property in styles) {_x000D_
          el.style[property] = styles[property];_x000D_
      }_x000D_
  }_x000D_
;_x000D_
_x000D_
cssStyle(element, { background:'tomato', color: 'white', padding: '0.5rem 1rem'});

<meta name="language" content="Spanish">

This isn't defined in any specification (including the HTML5 draft)

<meta http-equiv="content-language" content="es">

This is a poor man's version of a real HTTP header and should really be expressed in the headers. For example:

Content-language: es
Content-type: text/html;charset=UTF-8

It says that the document is intended for Spanish language speakers (it doesn't, however mean the document is written in Spanish; it could, for example, be written in English as part of a language course for Spanish speakers).

From the spec:

The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. Note that this might not be equivalent to all the languages used within the entity-body.

If you want to state that a document is written in Spanish then use:

<html lang="es">

Convert the string to an integer base 16 then to hexadecimal.

print hex(int(string, base=16))

These are built-in functions.

http://docs.python.org/2/library/functions.html#int

Example

>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa
>>> 

not sure whether its "fast" or not, but normally, one can do this

dicta = {"a":1,"b":2,"c":3,"d":4}
dictb = {"a":1,"d":2}
for key in dicta.keys():
    if not key in dictb:
        print key

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.

I was using the HTTP_ACCEPT_LANGUAGE header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.

Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).

Try the following code:

moment(startDate).startOf('months')
moment(startDate).endOf('months')

To add a prefix to all files and folders in the current directory using util-linux's rename (as opposed to prename, the perl variant from Debian and certain other systems), you can do:

rename '' <prefix> *

This finds the first occurrence of the empty string (which is found immediately) and then replaces that occurrence with your prefix, then glues on the rest of the file name to the end of that. Done.

For suffixes, you need to use the perl version or use find.

Use  

It is the entity used to represent a non-breaking space. It is essentially a standard space, the primary difference being that a browser should not break (or wrap) a line of text at the point that this   occupies.

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something'

Non-breaking Space

A common character entity used in HTML is the non-breaking space ( ).

Remember that browsers will always truncate spaces in HTML pages. If you write 10 spaces in your text, the browser will remove 9 of them. To add real spaces to your text, you can use the   character entity.

http://www.w3schools.com/html/html_entities.asp

Demo

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something';_x000D_
_x000D_
document.body.innerHTML = a;

Please check this jQuery plugin,

blockUI

with this you can overlay all the page or elements, works great for me,

Examples: Block a div: $('div.test').block({ message: null });

Block the page: $.blockUI({ message: '<h1><img src="busy.gif" /> Just a moment...</h1>' }); Hope that help someone

tl;dr It is restarting with a status code of 127, meaning there is a missing file/library in your container. Starting a fresh container just might fix it.

Explanation:

As far as my understanding of Docker goes, this is what is happening:

1. Container tries to start up. In the process, it tries to access a file/library which does not exist.
2. It exits with a status code of 127, which is explained in this answer.
3. Normally, this is where the container should have completely exited, but it restarts.
4. It restarts because the restart policy must have been set to something other than no (the default), (using either the command line flag --restart or the docker-compose.yml key restart) while starting the container.

Solution: Something might have corrupted your container. Starting a fresh container should ideally do the job.

You need to do this:

    exec procName 
    @parameter_1_Name = 'parameter_1_Value', 
    @parameter_2_name = 'parameter_2_value',
    @parameter_z_name = 'parameter_z_value'

This simplistic version also works.

public void UploadMultipart(byte[] file, string filename, string contentType, string url)
{
    var webClient = new WebClient();
    string boundary = "------------------------" + DateTime.Now.Ticks.ToString("x");
    webClient.Headers.Add("Content-Type", "multipart/form-data; boundary=" + boundary);
    var fileData = webClient.Encoding.GetString(file);
    var package = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"file\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n{3}\r\n--{0}--\r\n", boundary, filename, contentType, fileData);

    var nfile = webClient.Encoding.GetBytes(package);

    byte[] resp = webClient.UploadData(url, "POST", nfile);
}

Add any extra required headers if needed.

Try this:

BufferedReader br = new BufferedReader(new FileReader("java_module_name/src/file_name.txt"));

Here's a method, not a library, which seems to work for me.

The goals here are to be terse, each argument parsed by a single line, the args line up for readability, the code is simple and doesn't depend on any special modules (only os + sys), warns about missing or unknown arguments gracefully, use a simple for/range() loop, and works across python 2.x and 3.x

Shown are two toggle flags (-d, -v), and two values controlled by arguments (-i xxx and -o xxx).

import os,sys

def HelpAndExit():
    print("<<your help output goes here>>")
    sys.exit(1)

def Fatal(msg):
    sys.stderr.write("%s: %s\n" % (os.path.basename(sys.argv[0]), msg))
    sys.exit(1)

def NextArg(i):
    '''Return the next command line argument (if there is one)'''
    if ((i+1) >= len(sys.argv)):
        Fatal("'%s' expected an argument" % sys.argv[i])
    return(1, sys.argv[i+1])

### MAIN
if __name__=='__main__':

    verbose = 0
    debug   = 0
    infile  = "infile"
    outfile = "outfile"

    # Parse command line
    skip = 0
    for i in range(1, len(sys.argv)):
        if not skip:
            if   sys.argv[i][:2] == "-d": debug ^= 1
            elif sys.argv[i][:2] == "-v": verbose ^= 1
            elif sys.argv[i][:2] == "-i": (skip,infile)  = NextArg(i)
            elif sys.argv[i][:2] == "-o": (skip,outfile) = NextArg(i)
            elif sys.argv[i][:2] == "-h": HelpAndExit()
            elif sys.argv[i][:1] == "-":  Fatal("'%s' unknown argument" % sys.argv[i])
            else:                         Fatal("'%s' unexpected" % sys.argv[i])
        else: skip = 0

    print("%d,%d,%s,%s" % (debug,verbose,infile,outfile))

The goal of NextArg() is to return the next argument while checking for missing data, and 'skip' skips the loop when NextArg() is used, keeping the flag parsing down to one liners.

For a somewhat narrow use case, docker issue 8838 mentions this sort-of-hack:

You just stop docker daemon and change container config in /var/lib/docker/containers/[container-id]/config.json (sic)

This solution updates the environment variables without the need to delete and re-run the container, having to migrate volumes and remembering parameters to run.

However, this requires a restart of the docker daemon. And, until issue issue 2658 is addressed, this includes a restart of all containers.

$dateValue = '2012-01-05';
$yeararray = explode("-", $dateValue);

echo "Year : ". $yeararray[0];
echo "Month : ". date( 'F', mktime(0, 0, 0, $yeararray[1]));

Usiong explode() this can be done.

And with Prototype:

$('yourDivId').setStyle({top: '100px', left:'80px'});

I would suggest the following for Java8+.

/**

    final Path path = Paths.get(target);

    if(Files.notExists(path)){
        LOG.info("Target file \"" + target + "\" will be created.");
        return Files.createFile(Files.createDirectories(path)).toFile();
    }
    LOG.info("Target file \"" + target + "\" will be retrieved.");
    return path.toFile();
}

/**
 * Deletes the target if it exists then creates a new empty file.
 */
private File createOrReplaceFileAndDirectories(final String target) throws IOException{

    final Path path = Paths.get(target);
    // Create only if it does not exist already
    Files.walk(path)
        .filter(p -> Files.exists(p))
        .sorted(Comparator.reverseOrder())
        .peek(p -> LOG.info("Deleted existing file or directory \"" + p + "\"."))
        .forEach(p -> {
            try{
                Files.createFile(Files.createDirectories(p));
            }
            catch(IOException e){
                throw new IllegalStateException(e);
            }
        });

    LOG.info("Target file \"" + target + "\" will be created.");

    return Files.createFile(
        Files.createDirectories(path)
    ).toFile();
}

Dim strSQL As String
Dim rs As DAO.Recordset

strSQL = "tblTeachers"
'For the purposes of this post, we are simply going to make 
'strSQL equal to tblTeachers.
'You could use a full SELECT statement such as:
'SELECT * FROM tblTeachers (this would produce the same result in fact).
'You could also add a Where clause to filter which records are returned:
'SELECT * FROM tblTeachers Where ZIPPostal = '98052'

Recordsets have two important properties when looping through data, EOF (End-Of-File) and BOF (Beginning-Of-File). Recordsets are like tables and when you loop through one, you are literally moving from record to record in sequence. As you move through the records the EOF property is set to false but after you try and go past the last record, the EOF property becomes true. This works the same in reverse for the BOF property.

These properties let us know when we have reached the limits of a recordset.

Reinstall node, then update npm.

No need to get too complicated. If all you need is ² then use the unicode representation.

You can accomplish that now with display: grid:

Although the grid itself is not flexbox, it behaves very similar to a flexbox container, and the items inside the grid can be flex.

The grid layout is also very handy in the case you want responsive grids. That is, if you want the grid to have a different number of columns per row you can then just change grid-template-columns:

grid-template-columns: repeat(1, 1fr); // 1 column
grid-template-columns: repeat(2, 1fr); // 2 columns
grid-template-columns: repeat(3, 1fr); // 3 columns

and so on...

You can mix it with media queries and change according to the size of the page.

Sadly there is still no support for container queries / element queries in the browsers (out of the box) to make it work well with changing the number of columns according to the container size, not to the page size (this would be great to use with reusable webcomponents).

How to create CascadeClassifier :

1. Open this link : https://github.com/opencv/opencv/tree/master/data/haarcascades
2. Right click on where you find "haarcascade_frontalface_default.xml"
3. Click on "Save link as"
4. Save it into the same folder in which your file is.
5. Include this line in your file face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

With FluidXML you can generate and store an XML document very easily.

$doc = fluidxml();

$doc->add('Album', true)
        ->add('Track', 'Track Title');

$doc->save('album.xml');

Loading a document from a file is equally simple.

$doc = fluidify('album.xml');

$doc->query('//Track')
        ->attr('id', 123);

If all that you want is to see the disassembly with the INTC call, use objdump -d as someone mentioned but use the -static option when compiling. Otherwise the fopen function is not compiled into the elf and is linked at runtime.

string[] fileEntries = Directory.GetFiles(directoryPath);

foreach (var file_name in fileEntries){
    string fileName = file_name.Substring(directoryPath.Length + 1);
    Console.WriteLine(fileName);
}

Adding another simple alternative that is quite elegant in my opinion.

Your plot:

plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

Legend:

legend("bottomright", c("group A", "group B"), pch=c(1,2), lty=c(1,2),
       inset=c(0,1), xpd=TRUE, horiz=TRUE, bty="n"
       )

Result:

Here only the second line of the legend was added to your example. In turn:

• inset=c(0,1) - moves the legend by fraction of plot region in (x,y) directions. In this case the legend is at "bottomright" position. It is moved by 0 plotting regions in x direction (so stays at "right") and by 1 plotting region in y direction (from bottom to top). And it so happens that it appears right above the plot.
• xpd=TRUE - let's the legend appear outside of plotting region.
• horiz=TRUE - instructs to produce a horizontal legend.
• bty="n" - a style detail to get rid of legend bounding box.

Same applies when adding legend to the side:

par(mar=c(5,4,2,6))
plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2))
lines(1:3, rnorm(3), pch = 2, lty = 2, type="o")

legend("topleft", c("group A", "group B"), pch=c(1,2), lty=c(1,2),
       inset=c(1,0), xpd=TRUE, bty="n"
       )

Here we simply adjusted legend positions and added additional margin space to the right side of the plot. Result:

Through trial and error, it seems if the user was originally created "without login" then this query

select * from sys.database_principals

will show authentication_type = 0 (NONE).

Apparently these users cannot be re-linked to any login (pre-existing or new, SQL or Windows) since this command:

alter user [TempUser] with login [TempLogin]

responds with the Remap Error "Msg 33016" shown in the question.

Also these users do not show up in classic (deprecating) SP report:

If anyone knows a way around this or how to change authentication_type, please comment.

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

I had this problem just now and solved it by removing the --recursive option (which I had set) and using the same structure suggested above:

mochify "test/unit/**/*.js"

This ran all tests in all directories under /test/unit/ for me while ignoring the other directories within /test/

Your byte array is too small. Each pixel takes up 4 bytes, not just 1, so multiply your size * 4 so that the array is big enough.

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

Another way of declaring multi-dimentional arrays:

Array.fill(4,3)("")

res3: Array[Array[String]] = Array(Array("", "", ""), Array("", "", ""),Array("", "", ""), Array("", "", ""))

Just for your information,after add the "PATH",for my win7 i need to reboot it to get it work.

The number variables are the matches from the last successful match or substitution operator you applied:

my $string = 'abcdefghi';

if ($string =~ /(abc)def(ghi)/) {
    print "I found $1 and $2\n";
}

Always test that the match or substitution was successful before using $1 and so on. Otherwise, you might pick up the leftovers from another operation.

Perl regular expressions are documented in perlre.

This is another option to write a pandas dataframe directly into a matplotlib table:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

# hide axes
fig.patch.set_visible(False)
ax.axis('off')
ax.axis('tight')

df = pd.DataFrame(np.random.randn(10, 4), columns=list('ABCD'))

ax.table(cellText=df.values, colLabels=df.columns, loc='center')

fig.tight_layout()

plt.show()

Check with your host to see if they have any hourly limits to emails being sent.

Here is a good example for table scrolling across x and y way. Horizontal and vertical scrolling is the best thing for responsive table.

table, th, tr, td {
  border: 1px solid lightgrey;
  border-collapse: collapse;
  
}
tbody {
  max-height: 200px;
max-width: 200px;
  overflow: auto;
  display: block;
  table-layout: fixed;
}

tr {
  display: table;
}
