Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

import os 
zip_file_path = "C:\AA\BB"
file_list = os.listdir(path)
abs_path = []
for a in file_list:
    x = zip_file_path+'\\'+a
    print x
    abs_path.append(x)
for f in abs_path:
    zip=zipfile.ZipFile(f)
    zip.extractall(zip_file_path)

This does not contain validation for the file if its not zip. If the folder contains non .zip file it will fail.

Give this a try :P

I had similar issue when I had to install from github repo, but did not want to install git , etc.

The simple way to do it is using zip archive of the package. Add /zipball/master to the repo URL:

    $ pip install https://github.com/hmarr/django-debug-toolbar-mongo/zipball/master
Downloading/unpacking https://github.com/hmarr/django-debug-toolbar-mongo/zipball/master
  Downloading master
  Running setup.py egg_info for package from https://github.com/hmarr/django-debug-toolbar-mongo/zipball/master
Installing collected packages: django-debug-toolbar-mongo
  Running setup.py install for django-debug-toolbar-mongo
Successfully installed django-debug-toolbar-mongo
Cleaning up...

This way you will make pip work with github source repositories.

You can use a form that includes a submit button. Then use jQuery to prevent the default behavior of a form:

$(document).ready(function($) {_x000D_
  $(document).on('submit', '#submit-form', function(event) {_x000D_
    event.preventDefault();_x000D_
  _x000D_
    alert('page did not reload');_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>_x000D_
<form id='submit-form'>_x000D_
  <button type='submit'>submit</button>_x000D_
</form>

How do I set up the basic authorization?

All you need to do is use -u, --user USER[:PASSWORD]. Behind the scenes curl builds the Authorization header with base64 encoded credentials for you.

Example:

curl -u username:password -i -H 'Accept:application/json' http://example.com

If you aren't a fan of passing in a string, I prefer how @sesperanto has done it, except to make it even more concise, you could drop Float::INFINITY in the date range and instead simply use created_at: p[:date]..

Note.where(
    user_id: current_user.id,
    notetype: p[:note_type],
    created_at: p[:date]..
).order(:date, :created_at)

Take note that this will change the query to be >= instead of >. If that's a concern, you could always add a unit of time to the date by running something like p[:date] + 1.day..

If your using visual studio 2010 this error can occur when you change the configuration deployment type. The 3 types are x86, x64 and Mixed mode. Changing to mixed mode setting for all projects in solution should resolve the issue. Don't forget to delete the bin, Lib files and change the tempdirectory output if your an ASP.NET website.

I believe the Ajax response handler uses the HTTP status code to check if there was an error.

So if you just throw a Java exception on your server side code but then the HTTP response doesn't have a 500 status code jQuery (or in this case probably the XMLHttpRequest object) will just assume that everything was fine.

I'm saying this because I had a similar problem in ASP.NET where I was throwing something like a ArgumentException("Don't know what to do...") but the error handler wasn't firing.

I then set the Response.StatusCode to either 500 or 200 whether I had an error or not.

try:

string fileName = @"test.txt";
    string currentDirectory = Directory.GetCurrentDirectory();
    string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);

it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".

Everyone is saying to use isset() - which will probably work for you.

However, it's important that you understand the difference between

$_POST['x'] = NULL; and $_POST['x'] = '';

isset($_POST['x']) will return false on the first example, but will return true on the second one even though if you tried to print either one, both would return a blank value.

If your $_POST is coming from a user-inputted field/form and is left blank, I BELIEVE (I am not 100% certain on this though) that the value will be "" but NOT NULL.

Even if that assumption is incorrect (someone please correct me if I'm wrong!) the above is still good to know for future use.

For an activity you can use this approach to specify a subtitle, along with the title, in the manifest.

Manifest:

<activity
    android:name=".MyActivity"
    android:label="@string/my_title"
    android:description="@string/my_subtitle">
</activity>

Activity:

try {
    ActivityInfo activityInfo = getPackageManager().getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
    //String title = activityInfo.loadLabel(getPackageManager()).toString();
    int descriptionResId = activityInfo.descriptionRes;
    if (descriptionResId != 0) {
        toolbar.setSubtitle(Utilities.fromHtml(getString(descriptionResId)));
    }
}
catch(Exception e) {
    Log.e(LOG_TAG, "Could not get description/subtitle from manifest", e);
}

This way you only need to specify the title string once, and you get to specify the subtitle right alongside it.

You may also have a look on Runtyper - a tool that performs type checking of operands in === (and other operations).
For your example, if you have strict comparison x === y and x = 123, y = "123", it will automatically check typeof x, typeof y and show warning in console:

Strict compare of different types: 123 (number) === "123" (string)

In my case, Environment.NewLine was working fine while previewing the report in Visual Studio. But when I tried to publish the rdl to Dynamics 365 CE, I received the error "The report server has RDLSandboxing enabled and the Value expression for the text box 'Textbox10' contains a reference to a type, namespace, or member 'Environment' that is not allowed."

So I had to replace Environment.NewLine with vbcrlf.

For an object:

<select ng-model="mySelect" ng-options="key as value for (key, value) in object"></select>

[Update: Although I discovered this trick independently, I’ve since learned that Thierry Koblentz beat me to it. You can find his 2009 article on A List Apart. Credit where credit is due.]

I know this is an old question, but I encountered a similar problem that I did solve only with CSS. Here is my blog post that discusses the solution. Included in the post is a live example. Code is reposted below.

#container {
  display: inline-block;
  position: relative;
  width: 50%;
}

#dummy {
  margin-top: 75%;
  /* 4:3 aspect ratio */
}

#element {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: silver/* show me! */
}

<div id="container">
  <div id="dummy"></div>
  <div id="element">
    some text
  </div>
</div>

All the above answers are correct, but I noticed something very important. Leaving a space between the variable and the equal sign might result in a problem. For example, (?variablename =value)

Hmm..i tried everything to get url to user image.The perfect solution was fql use like this->

    $fql_b = 'SELECT pic from user where uid = ' . $user_id;
    $ret_obj_b = $facebook->api(array(
                               'method' => 'fql.query',
                               'query' => $fql_b,
                             ));


             $dp_url =$ret_obj_b[0]['pic'];

replace pic by big,pic_square to get other desired results. Hope IT HELPED....

If the InputStream you're using supports mark/reset support, you could also attempt to read the first byte of the stream and then reset it to its original position:

input.mark(1);
final int bytesRead = input.read(new byte[1]);
input.reset();
if (bytesRead != -1) {
    //stream not empty
} else {
    //stream empty
} 

If you don't control what kind of InputStream you're using, you can use the markSupported() method to check whether mark/reset will work on the stream, and fall back to the available() method or the java.io.PushbackInputStream method otherwise.

For recent SQL:

select * from v$sql

For history:

select * from dba_hist_sqltext

here's my 2 cents worth:

• resuable function forpromise()
• emulates a classic for loop
• allows for early exit based on internal logic, returning a value
• can collect an array of results passed into resolve/next/collect
• defaults to start=0,increment=1
• exceptions thrown inside loop are caught and passed to .catch()

And if you didn't want to use strict equality, you could use exists:

myFunction(strings.exists { x => customPredicate(x) })

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

Carry Flag is a flag set when:

a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.

b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.

Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)

Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.

You can read more about flags on wikipedia

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

I needed to achieve the same results, but using something more generic (as the type was not known). Thanks to marc's answer I finally figured out what I was trying to achieve:

    public static LambdaExpression CombineOr(Type sourceType, LambdaExpression exp, LambdaExpression newExp) 
    {
        var parameter = Expression.Parameter(sourceType);

        var leftVisitor = new ReplaceExpressionVisitor(exp.Parameters[0], parameter);
        var left = leftVisitor.Visit(exp.Body);

        var rightVisitor = new ReplaceExpressionVisitor(newExp.Parameters[0], parameter);
        var right = rightVisitor.Visit(newExp.Body);

        var delegateType = typeof(Func<,>).MakeGenericType(sourceType, typeof(bool));
        return Expression.Lambda(delegateType, Expression.Or(left, right), parameter);
    }

For me android:focusableInTouchMode="true" is the way to go. android:listSelector="@android:color/transparent" is of no use. Note that I am using a custom listview with a number of objects in each row.

for those of us that love all things pandas, apply, and of course lambda functions:

df['Col3'] = df[['Col1', 'Col2']].apply(lambda x: ''.join(x), axis=1)

From a web page this cannot work since IE restricts the use of that object.

It's best if you judge on your own,

1) Sublime works on Mac & Linux that may be its plus point, with VI mode that makes things easily searchable for the VI lover(UNIX & Linux).

I am not sure of your requirements, nor I am promoter of either of these editors :)

So, judge on basis of your requirements, this should satisfy you query...

Yes we can add that both are evolving and changing fast..

  int month = Convert.ToInt32(ddlMonth.SelectedValue);/*Store month Value From page*/
  int year = Convert.ToInt32(txtYear.Value);/*Store Year Value From page*/
  int days = System.DateTime.DaysInMonth(year, month); /*this will store no. of days for month, year that we store*/

For me it worked very simple:

1. Copy ".gitconfig" from old directory: to %USERPROFILE% (standard in "c:\users\username")
2. Right click on start-icons of GITGUI and GITBASH and change "run in": "%HOMEDRIVE%%HOMEPATH%" to "%USERPROFILE%". Of cource you can use any other directory instead of "%USERPROFILE%".

This is a common problem, so here's a relatively thorough illustration.

For non-unicode strings (i.e. those without u prefix like u'\xc4pple'), one must decode from the native encoding (iso8859-1/latin1, unless modified with the enigmatic sys.setdefaultencoding function) to unicode, then encode to a character set that can display the characters you wish, in this case I'd recommend UTF-8.

First, here is a handy utility function that'll help illuminate the patterns of Python 2.7 string and unicode:

>>> def tell_me_about(s): return (type(s), s)

A plain string

>>> v = "\xC4pple" # iso-8859-1 aka latin1 encoded string

>>> tell_me_about(v)
(<type 'str'>, '\xc4pple')

>>> v
'\xc4pple'        # representation in memory

>>> print v
?pple             # map the iso-8859-1 in-memory to iso-8859-1 chars
                  # note that '\xc4' has no representation in iso-8859-1, 
                  # so is printed as "?".

Decoding a iso8859-1 string - convert plain string to unicode

>>> uv = v.decode("iso-8859-1")
>>> uv
u'\xc4pple'       # decoding iso-8859-1 becomes unicode, in memory

>>> tell_me_about(uv)
(<type 'unicode'>, u'\xc4pple')

>>> print v.decode("iso-8859-1")
Äpple             # convert unicode to the default character set
                  # (utf-8, based on sys.stdout.encoding)

>>> v.decode('iso-8859-1') == u'\xc4pple'
True              # one could have just used a unicode representation 
                  # from the start

A little more illustration — with “Ä”

>>> u"Ä" == u"\xc4"
True              # the native unicode char and escaped versions are the same

>>> "Ä" == u"\xc4"  
False             # the native unicode char is '\xc3\x84' in latin1

>>> "Ä".decode('utf8') == u"\xc4"
True              # one can decode the string to get unicode

>>> "Ä" == "\xc4"
False             # the native character and the escaped string are
                  # of course not equal ('\xc3\x84' != '\xc4').

Encoding to UTF

>>> u8 = v.decode("iso-8859-1").encode("utf-8")
>>> u8
'\xc3\x84pple'    # convert iso-8859-1 to unicode to utf-8

>>> tell_me_about(u8)
(<type 'str'>, '\xc3\x84pple')

>>> u16 = v.decode('iso-8859-1').encode('utf-16')
>>> tell_me_about(u16)
(<type 'str'>, '\xff\xfe\xc4\x00p\x00p\x00l\x00e\x00')

>>> tell_me_about(u8.decode('utf8'))
(<type 'unicode'>, u'\xc4pple')

>>> tell_me_about(u16.decode('utf16'))
(<type 'unicode'>, u'\xc4pple')

Relationship between unicode and UTF and latin1

>>> print u8
Äpple             # printing utf-8 - because of the encoding we now know
                  # how to print the characters

>>> print u8.decode('utf-8') # printing unicode
Äpple

>>> print u16     # printing 'bytes' of u16
???pple

>>> print u16.decode('utf16')
Äpple             # printing unicode

>>> v == u8
False             # v is a iso8859-1 string; u8 is a utf-8 string

One would get around these by converting from the specific encoding (latin-1, utf8, utf16) to unicode e.g. u8.decode('utf8').encode('latin1').

So perhaps one could draw the following principles and generalizations:

• a type str is a set of bytes, which may have one of a number of encodings such as Latin-1, UTF-8, and UTF-16
• a type unicode is a set of bytes that can be converted to any number of encodings, most commonly UTF-8 and latin-1 (iso8859-1)
• the print command has its own logic for encoding, set to sys.stdout.encoding and defaulting to UTF-8
• One must decode a str to unicode before converting to another encoding.

Of course, all of this changes in Python 3.x.

Hope that is illuminating.

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

also commenting the line --execute format('alter sequence will give the list, not actually resetting the value

Instead of Button use LinearLayout with ImageView and TextView inside. In child items like ImageView and TextView use android:duplicateParentState="true".

You can also use &, | (and/or) for more flexibility:

values between 5 and 10: A[(A>5)&(A<10)]

values greater than 10 or smaller than 5: A[(A<5)|(A>10)]

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

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

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

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

Short answer: you can't. AngularJS won't allow you to inject services into the config because it can't be sure they have been loaded correctly.

See this question and answer: AngularJS dependency injection of value inside of module.config

A module is a collection of configuration and run blocks which get applied to the application during the bootstrap process. In its simplest form the module consist of collection of two kinds of blocks:

Configuration blocks - get executed during the provider registrations and configuration phase. Only providers and constants can be injected into configuration blocks. This is to prevent accidental instantiation of services before they have been fully configured.

Use a couple of functions and a boolean. Here's a pattern, not full code:

 var state = false,
     oddONes = function () {...},
     evenOnes = function() {...};

 $("#time").click(function(){
     if(!state){
        evenOnes();
     } else {
        oddOnes();
     }
     state = !state;
  });

Or

  var cases[] = {
      function evenOnes(){...},  // these could even be anonymous functions
      function oddOnes(){...}    // function(){...}
  };

  var idx = 0; // should always be 0 or 1

  $("#time").click(function(idx){cases[idx = ((idx+1)%2)]()}); // corrected

(Note the second is off the top of my head and I mix languages a lot, so the exact syntax isn't guaranteed. Should be close to real Javascript through.)

Just small reusable class (Swift 4.1)

class View: NSView {

   var backgroundColor: NSColor?

   convenience init() {
      self.init(frame: NSRect())
   }

   override func draw(_ dirtyRect: NSRect) {
      if let backgroundColor = backgroundColor {
         backgroundColor.setFill()
         dirtyRect.fill()
      } else {
         super.draw(dirtyRect)
      }
   }
}

// Usage
let view = View()
view.backgroundColor = .white

There are some cases when such a cast would make sense.
I my case, I was receiving a BASE class over the network, and I needed more features to it. So deriving it to handle it on my side with all the bells and whistles I wanted, and casting the received BASE class into the DERIVED one was simply not an option (Throws InvalidCastException of Course)

One practical think-out-of-the-box SOLUTION was to declare an EXTENSION Helper class that was NOT inheriting BASE class actually, but INCLUDING IT as a member.

public class BaseExtension
{
   Base baseInstance;

   public FakeDerived(Base b)
   {
      baseInstance = b;
   }

   //Helper methods and extensions to Base class added here
}

If you have loose coupling and just need a couple of extra features to base class without REALLY having an absolute need of derivation, that could be a quick and simple workaround.

In many regex dialects, /[\S\s]*<Foobar>/ will do just what you want. Source

Yes! : Android Scripting Environment

An example via Matt Cutts via SL4A -- "here’s a barcode scanner written in six lines of Python code:

import android
droid = android.Android()
code = droid.scanBarcode()
isbn = int(code['result']['SCAN_RESULT'])
url = "http://books.google.com?q=%d" % isbn
droid.startActivity('android.intent.action.VIEW', url)

I wrote a simpler loop that works too (note that all my values are unique):

HashMap<Character, String> myHashMap = new HashMap<Character, String>();
HashMap<String, Character> reversedHashMap = new HashMap<String, Character>();

for (char i : myHashMap.keySet()) {
    reversedHashMap.put(myHashMap.get(i), i);
}

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

This is how I do it:

public static String readFromAssets(Context context, String filename) throws IOException {
    BufferedReader reader = new BufferedReader(new InputStreamReader(context.getAssets().open(filename)));

    // do reading, usually loop until end of file reading  
    StringBuilder sb = new StringBuilder();
    String mLine = reader.readLine();
    while (mLine != null) {
        sb.append(mLine); // process line
        mLine = reader.readLine();
    }
    reader.close();
    return sb.toString();
}

use it as follows:

readFromAssets(context,"test.txt")

You can also use the DeleteAllOnSubmit() method by passing it your results in a generic list rather than in var. This way your foreach reduces to one line of code:

List<Widgets> widgetList = context.Widgets
              .Where(w => w.WidgetId == widgetId).ToList<Widgets>();

context.Widgets.DeleteAllOnSubmit(widgetList);

context.SubmitChanges();

It probably still uses a loop internally though.

char str[]= "Hello\0";

That would be 7 bytes.

In memory it'd be:

48 65 6C 6C 6F 00 00
H  e  l  l  o  \0 \0

Edit:

• What does the \0 symbol mean in a C string?
  It's the "end" of a string. A null character. In memory, it's actually a Zero. Usually functions that handle char arrays look for this character, as this is the end of the message. I'll put an example at the end.

• What is the length of str array? (Answered before the edit part)
  7

• and with how much 0s it is ending?
  You array has two "spaces" with zero; str[5]=str[6]='\0'=0

Extra example:
Let's assume you have a function that prints the content of that text array. You could define it as:

char str[40];

Now, you could change the content of that array (I won't get into details on how to), so that it contains the message: "This is just a printing test" In memory, you should have something like:

54 68 69 73 20 69 73 20 6a 75 73 74 20 61 20 70 72 69 6e 74
69 6e 67 20 74 65 73 74 00 00 00 00 00 00 00 00 00 00 00 00

So you print that char array. And then you want a new message. Let's say just "Hello"

48 65 6c 6c 6f 00 73 20 6a 75 73 74 20 61 20 70 72 69 6e 74
69 6e 67 20 74 65 73 74 00 00 00 00 00 00 00 00 00 00 00 00

Notice the 00 on str[5]. That's how the print function will know how much it actually needs to send, despite the actual longitude of the vector and the whole content.

I do not have factual evidence to prove this but I already ran into this issue. It seems that triggering a click() event on an <a> tag doesn't seem to behave the same way you would expect with say, a input button.

The workaround I employed was to set the location.href property on the window which causes the browser to load the request resource like so:

$(document).ready(function()
{
      var href = $('.cssbuttongo').attr('href');
      window.location.href = href; //causes the browser to refresh and load the requested url
   });
});

Edit:

I would make a js fiddle but the nature of the question intermixed with how jsfiddle uses an iframe to render code makes that a no go.

Use mktime():

<?php
 $monthNum = 5;
 $monthName = date("F", mktime(0, 0, 0, $monthNum, 10));
 echo $monthName; // Output: May
?>

See the PHP manual : http://php.net/mktime

writelines() does not add line separators. You can alter the list of strings by using map() to add a new \n (line break) at the end of each string.

items = ['abc', '123', '!@#']
items = map(lambda x: x + '\n', items)
w.writelines(items)

You can use Janel. This last works as an application launcher or service launcher (available from 4.x).

Maybe you could try out this: http://cometaddin.codeplex.com/

You can do

[n.name for n in tf.get_default_graph().as_graph_def().node]

Also, if you are prototyping in an IPython notebook, you can show the graph directly in notebook, see show_graph function in Alexander's Deep Dream notebook

The type of expression

" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'"

is std::string. However function system has declaration

int system(const char *s);

that is it accepts an argumnet of type const char *

There is no conversion operator that would convert implicitly an object of type std::string to object of type const char *.

Nevertheless class std::string has two functions that do this conversion explicitly. They are c_str() and data() (the last can be used only with compiler that supports C++11)

So you can write

string name = "john";

system( (" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str() );

There is no need to use an intermediate variable for the expression.

Thanks to dee for the answer above with the Scrape() subroutine. The code worked perfectly as written, and I was able to then convert the code to work with the specific website I am trying to scrape.

I do not have enough reputation to upvote or to comment, but I do actually have some minor improvements to add to dee's answer:

1. You will need to add the VBA Reference via "Tools\References" to "Microsoft HTML Object Library in order for the code to compile.

2. I commented out the Browser.Visible line and added the comment as follows

   'if you need to debug the browser page, uncomment this line:
   'Browser.Visible = True
   

3. And I added a line to close the browser before Set Browser = Nothing:

   Browser.Quit
   

Thanks again dee!

ETA: this works on machines with IE9, but not machines with IE8. Anyone have a fix?

Found the fix myself, so came back here to post it. The ClassName function is available in IE9. For this to work in IE8, you use querySelectorAll, with a dot preceding the class name of the object you are looking for:

'Set repList = doc.getElementsByClassName("reportList") 'only works in IE9, not in IE8
Set repList = doc.querySelectorAll(".reportList")       'this works in IE8+

There is a blog post with some C# sample code on how to do it here.

I just get it working by including select2.min.css

Try iy out

My modal html of bootstrap 3 is

<div id="changeTransportUserRequestPopup" class="modal fade" role="dialog">
    <div class="modal-dialog" style="width: 40%!important; ">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h3>Warning</h3>
            </div>
            <div class="modal-body" id="changeTransportUserRequestPopupBody">
                <select id="cbTransport" class="js-example-basic-single" name="cbTransport" style="width:100%!important;"></select>
            </div>
            <div class="modal-footer">
                <button id="noPost" class="btn btn-default" name="postConfirm" value="false" data-dismiss="modal">Cancel</button>
                <button type="submit" id="yesChangeTransportPost" class="btn btn-success" name="yesChangeTransportPost" value="true" data-dismiss="modal">Yes</button>
            </div>
        </div>
    </div>
</div>

Also, in some cases is important to check the target folder permissions. To give write permission for the user might be the solution. That worked for me.

I think it's a version problem, you just have to uninstall the old version of composer, then do a new installation of its new version.

 apt remove composer

and follow the steps:

1. download the composer from its official release site by making use of the following command.

 wget https://getcomposer.org/download/1.6.3/composer.phar

2. Before you proceed with the installation, you should rename before you install and make it an executable file.

  mv composer.phar composer

  chmod +x composer

3. Now install the package by making use the following command.

 ./composer

4. The composer has been successfully installed now, make it access globally using the following command. for Ubuntu 16

 mv composer /usr/bin/

for Ubuntu 18

 mv composer /usr/local/bin/

in my test.

close will send fin packet and destroy fd immediately when socket is not shared with other processes

shutdown SHUT_RD, process can still recv data from the socket, but recv will return 0 if TCP buffer is empty.After peer send more data, recv will return data again.

shutdown SHUT_WR will send fin packet to indicate the Further sends are disallowed. the peer can recv data but it will recv 0 if its TCP buffer is empty

shutdown SHUT_RDWR (equal to use both SHUT_RD and SHUT_WR) will send rst packet if peer send more data.

My requirement is to check if specific software is installed in my system. This solution works as expected. It might help you. I used a windows application in c# with visual studio 2015.

 private void Form1_Load(object sender, EventArgs e)
        {

            object line;
            string softwareinstallpath = string.Empty;
            string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
            using (var baseKey = Microsoft.Win32.RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
            {
                using (var key = baseKey.OpenSubKey(registry_key))
                {
                    foreach (string subkey_name in key.GetSubKeyNames())
                    {
                        using (var subKey = key.OpenSubKey(subkey_name))
                        {
                            line = subKey.GetValue("DisplayName");
                            if (line != null && (line.ToString().ToUpper().Contains("SPARK")))
                            {

                                softwareinstallpath = subKey.GetValue("InstallLocation").ToString();
                                listBox1.Items.Add(subKey.GetValue("InstallLocation"));
                                break;
                            }
                        }
                    }
                }
            }

            if(softwareinstallpath.Equals(string.Empty))
            {
                MessageBox.Show("The Mirth connect software not installed in this system.")
            }



            string targetPath = softwareinstallpath + @"\custom-lib\";
            string[] files = System.IO.Directory.GetFiles(@"D:\BaseFiles");

            // Copy the files and overwrite destination files if they already exist. 
            foreach (var item in files)
            {
                string srcfilepath = item;
                string fileName = System.IO.Path.GetFileName(item);
                System.IO.File.Copy(srcfilepath, targetPath + fileName, true);
            }
            return;

        }

Lookarounds can be nested.

So this regex matches "drupal-6.14/" that is not followed by "sites" that is not followed by "/all" or "/default".

Confusing? Using different words, we can say it matches "drupal-6.14/" that is not followed by "sites" unless that is further followed by "/all" or "/default"

public static boolean stringToBool(String s) {
        s = s.toLowerCase();
        Set<String> trueSet = new HashSet<String>(Arrays.asList("1", "true", "yes"));
        Set<String> falseSet = new HashSet<String>(Arrays.asList("0", "false", "no"));

        if (trueSet.contains(s))
            return true;
        if (falseSet.contains(s))
            return false;

        throw new IllegalArgumentException(s + " is not a boolean.");
    }

My way to convert string to boolean.

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

CSS
select{
  color:red;
 }

HTML
<select id="sel" onclick="document.getElementById('sel').style.color='green';">
 <option>Select Your Option</option>
 <option value="">INDIA</option>
 <option value="">USA</option>
</select>

The above code will change the colour of text on click of the select box.

and if you want every option different colour, give separate class or id to all options.

When this question was asked, Chrome didn't support the Disable Cache feature. But now, you can find the "Disable Cache" feature in Network Tab in Chrome Dev Tools.

Network Tab with Cache Disabled

You can see that all the resources (I have filtered JS resources) have been fetched from network and not loaded from disk/memory cache.

Disable Cache not selected

You can see that when I refreshed the page but didn't select the "Disable Cache" feature, almost all the resources were loaded from Cache.

This works fine for local web development but there are certain limitations that I'd like to highlight. You can stop reading here if the solution discussed so far meets your use case.

Limitations

1. You have to keep the DevTools Open and Disable Cache Selected
2. When you disable the cache, it is disabled for all the resources in that tab. It makes things slow and is inefficient if you want to disable cache for only 1-2 resources

Using Requestly Chrome Extension to disable Cache for particular resources (JS/CSS/Images, etc)

Recently, I stumbled upon https://medium.com/weekly-webtips/how-to-disable-caching-of-particular-js-css-file-84a93d005172 which helped me understand how you can disable cache for specific resources.

The trick here is to add a query parameter to your resource with random value every time the request is made. Using Requestly Query Param Rule, you can add a param like this

URL Contains mywebsite.com/myresource.js
Add param cb rq_rand(4)

rq_rand(4) is replaced by 4 digits random number when a request is made.

Requestly Query Parameter Rule to add random parameter

After adding the rule, JS/CSS files are not cached

Here you can see that "Disable Cache" is not selected and still the resources are not loaded from Cache because of a random parameter (cb - Read it as Cache buster) in the URL.

1. The good thing is you don't need to keep your dev tools open for having this behavior
2. You can keep this permanently ON and your browsing experience won't be affected too.

How to get the Rule

Here is the link using which you can browse & download the rule if you have Requestly installed - https://app.requestly.io/rules/#sharedList/1600501411585-disable-cache-stackoverflow

Disclaimer: I built Requestly but I think this could be helpful to a lot of web developers and hence sharing here.

I have used:

let originY: CGFloat = self.navigationController!.navigationBar.frame.maxY

Working great if you want to get the navigation bar height AND its Y origin.

If fptr is NULL, then you don't have an open file. Therefore, you can't freopen it, you should just fopen it.

FILE *fptr;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
    fptr = fopen("scores.dat", "wb");
}

note: Since the behavior of your program varies depending on whether the file is opened in read or write modes, you most probably also need to keep a variable indicating which is the case.

A complete example

int main()
{
    FILE *fptr;

For the particular case of splitting strings into words I've come across another solution for SQL Server 2008.

with testTable AS
(
SELECT 1 AS Id, N'how now brown cow' AS txt UNION ALL
SELECT 2, N'she sells sea shells upon the sea shore' UNION ALL
SELECT 3, N'red lorry yellow lorry' UNION ALL
SELECT 4, N'the quick brown fox jumped over the lazy dog'
)

SELECT display_term, COUNT(*) As Cnt
 FROM testTable
CROSS APPLY sys.dm_fts_parser('"' + txt + '"', 1033, 0,0)
GROUP BY display_term
HAVING COUNT(*) > 1
ORDER BY Cnt DESC

Returns

display_term                   Cnt
------------------------------ -----------
the                            3
brown                          2
lorry                          2
sea                            2

Something like this:

$(myObj).attr({"data-test-1": num1, "data-test-2": num2});

Five problems:

1. Don't put a space before or after the equal sign.
2. Use "$(...)" to get the output of a command as text.
3. [ is a command. Put a space between it and the arguments.
4. Commands are case-sensitive. You want echo.
5. Use double quotes around variables. rm "$folderToBeMoved"

eta: There's a killer article on this stuff by SO's own @Nick Craver that you should read

While the other responses say this, they don't make it explicit, so I will....

On VS2013.2, to actually trigger the emission of the cited information, you need to not read the message, which says:

C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets(1697,5): warning MSB3277: Found conflicts between different versions of the same dependent assembly that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed.

This is incorrect (or at least it was for some versions of Visual Studio - it seems to be OK on an up to date VS2015 Update 3 or later). Instead turn it to Diagnostic (from Tools->Options->Project and Solutions->Build and Run, set MSBuild project build output verbosity), whereupon you'll see messages such as:

There was a conflict between "Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" and "Newtonsoft.Json, Version=6.0.5.17707, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed".

• "Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" was chosen because it was primary and "Newtonsoft.Json, Version=6.0.5.17707, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" was not.

Then

• Ctrl-Alt-O to go to Build output window
• search for "was chosen" to find the drilldown.

...And yes, for those looking at the detail of the [diagnostic] message, it was news to this ignoramus that there's a convention in town whereby all 6.x versions are, internally Assembly Version 6.0.0.0, i.e. only the SemVer Major component goes into the Assembly Version :)

This issue occurs whenever you call a context which is unavailable or null when you call it. This can be a situation when you are calling main activity thread's context on a background thread or background thread's context on main activity thread.

For instance , I updated my shared preference string like following.

editor.putString("penname",penNameEditeText.getText().toString());
editor.commit();
finish();

And called finish() right after it. Now what it does is that as commit runs on main thread and stops any other Async commits if coming until it finishes. So its context is alive until the write is completed. Hence previous context is live , causing the error to occur.

So make sure to have your code rechecked if there is some code having this context issue.

I know Edwin answered it above but his only prints one document. I use this code to print all files from a given directory.

public void PrintAllFiles()
{
    System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo();
    info.Verb = "print";
    System.Diagnostics.Process p = new System.Diagnostics.Process();
    //Load Files in Selected Folder
    string[] allFiles = System.IO.Directory.GetFiles(Directory);
    foreach (string file in allFiles)
    {
        info.FileName = @file;
        info.CreateNoWindow = true;
        info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
         p.StartInfo = info;
        p.Start();
    }
    //p.Kill(); Can Create A Kill Statement Here... but I found I don't need one
    MessageBox.Show("Print Complete");
}

It essentually cycles through each file in the given directory variable Directory - > for me it was @"C:\Users\Owner\Documents\SalesVaultTesting\" and prints off those files to your default printer.

dict1 = {'m': 2, 'n': 4}
dict2 = {'n': 3, 'm': 1}

Making sure that the keys are in the same order:

dict2_sorted = {i:dict2[i] for i in dict1.keys()}

keys = dict1.keys()
values = zip(dict1.values(), dict2_sorted.values())
dictionary = dict(zip(keys, values))

gives:

{'m': (2, 1), 'n': (4, 3)}

If you are using zsh do the following.

1. Open .zshrc file nano $HOME/.zshrc

2. You will see the commented $PATH variable here

   # If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/...

3. Remove the comment symbol(#) and append your new path using a separator(:) like this.

export PATH=$HOME/bin:/usr/local/bin:/Users/ebin/Documents/Softwares/mongoDB/bin:$PATH

4. Activate the change source $HOME/.zshrc

You're done !!!

Capslock + Tab to indent multiple lines at once. Highlight the text first.

Here's a dead simple usage of multiprocessing.Queue and multiprocessing.Process that allows callers to send an "event" plus arguments to a separate process that dispatches the event to a "do_" method on the process. (Python 3.4+)

import multiprocessing as mp
import collections

Msg = collections.namedtuple('Msg', ['event', 'args'])

class BaseProcess(mp.Process):
    """A process backed by an internal queue for simple one-way message passing.
    """
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.queue = mp.Queue()

    def send(self, event, *args):
        """Puts the event and args as a `Msg` on the queue
        """
       msg = Msg(event, args)
       self.queue.put(msg)

    def dispatch(self, msg):
        event, args = msg

        handler = getattr(self, "do_%s" % event, None)
        if not handler:
            raise NotImplementedError("Process has no handler for [%s]" % event)

        handler(*args)

    def run(self):
        while True:
            msg = self.queue.get()
            self.dispatch(msg)

Usage:

class MyProcess(BaseProcess):
    def do_helloworld(self, arg1, arg2):
        print(arg1, arg2)

if __name__ == "__main__":
    process = MyProcess()
    process.start()
    process.send('helloworld', 'hello', 'world')

The send happens in the parent process, the do_* happens in the child process.

I left out any exception handling that would obviously interrupt the run loop and exit the child process. You can also customize it by overriding run to control blocking or whatever else.

This is really only useful in situations where you have a single worker process, but I think it's a relevant answer to this question to demonstrate a common scenario with a little more object-orientation.

Followed Mark's advise and did this to set the default number formatting to text in the whole workbook:

$objPHPExcel = new PHPExcel(); 
$objPHPExcel->getDefaultStyle()
    ->getNumberFormat()
    ->setFormatCode(
        PHPExcel_Style_NumberFormat::FORMAT_TEXT
    );

And it works flawlessly. Thank you, Mark Baker.

You could use HTML entities:

• ' for '
• " for "
• ...

For more, you can take a look at Character entity references in HTML.

    public class Example1 extends FragmentActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
          DemoFragment fragmentDemo = (DemoFragment) 
          getSupportFragmentManager().findFragmentById(R.id.frame_container);
          //above part is to determine which fragment is in your frame_container
          setFragment(fragmentDemo);
                       (OR)
          setFragment(new TestFragment1());
        }

        // This could be moved into an abstract BaseActivity 
        // class for being re-used by several instances
        protected void setFragment(Fragment fragment) {
            FragmentManager fragmentManager = getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = 
                fragmentManager.beginTransaction();
            fragmentTransaction.replace(android.R.id.content, fragment);
            fragmentTransaction.commit();
        }
    }

To add a fragment into a Activity or FramentActivity it requires a Container. That container should be a "Framelayout", which can be included in xml or else you can use the default container for that like "android.R.id.content" to remove or replace a fragment in Activity.

main.xml

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
 <!-- Framelayout to display Fragments -->
   <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ImageView
        android:id="@+id/imagenext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_margin="16dp"
        android:src="@drawable/next" />
</RelativeLayout>

If the script you want to load is in the same directory than the one you run, maybe "import" will do the job ?

If you need to dynamically import code the built-in function __ import__ and the module imp are worth looking at.

>>> import sys
>>> sys.path = ['/path/to/script'] + sys.path
>>> __import__('test')
<module 'test' from '/path/to/script/test.pyc'>
>>> __import__('test').run()
'Hello world!'

test.py:

def run():
        return "Hello world!"

If you're using Python 3.1 or later, you should also take a look at importlib.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

If you can live with 01 for January instead of 1, then try...

d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

You can check the docs for other formatting directives.

Just to build upon solving the namespace issues, in my case I've been running into documents with multiple namespaces and needed to handle namespaces properly. I wrote the function below to get a namespace manager to deal with any namespace in the document:

private XmlNamespaceManager GetNameSpaceManager(XmlDocument xDoc)
    {
        XmlNamespaceManager nsm = new XmlNamespaceManager(xDoc.NameTable);
        XPathNavigator RootNode = xDoc.CreateNavigator();
        RootNode.MoveToFollowing(XPathNodeType.Element);
        IDictionary<string, string> NameSpaces = RootNode.GetNamespacesInScope(XmlNamespaceScope.All);

        foreach (KeyValuePair<string, string> kvp in NameSpaces)
        {
            nsm.AddNamespace(kvp.Key, kvp.Value);
        }

        return nsm;
    }

The only thing I see is that it's supposed to be since Midnight Jan 1, 1970 UTC

TimeSpan span= DateTime.Now.Subtract(new DateTime(1970,1,1,0,0,0, DateTimeKind.Utc));
return span.TotalSeconds;

Here is a great explaination on this!

Also implements loading delays and timeouts!

If by "empty" you mean undefined, it is the way ng-expressions are interpreted. Then, you could use :

<a ng-if="!item.photo" href="#/details/{{item.id}}"><img src="/img.jpg" class="img-responsive"></a>

If you'd like to do it for all dialogs throughout the site try the following code...

$.extend( $.ui.dialog.prototype.options, { 
    open: function() {
        var dialog = this;
        $('.ui-widget-overlay').bind('click', function() {
            $(dialog).dialog('close');
        });
    }   

});

I suggest forgoing the 1990's modal dialogs and instead implementing a control as an overlay (canvas+absolute positioning) with visibility tied to a boolean back in the VM. Closer to an ajax type control.

This is very useful:

<BooleanToVisibilityConverter x:Key="booltoVis" />

as in:

<my:ErrorControl Visibility="{Binding Path=ThereWasAnError, Mode=TwoWay, Converter={StaticResource booltoVis}, UpdateSourceTrigger=PropertyChanged}"/>

Here's how I have one implemented as a user control. Clicking on the 'x' closes the control in a line of code in the usercontrol's code behind. (Since I have my Views in an .exe and ViewModels in a dll, I don't feel bad about code that manipulates UI.)

Here is the full program

import java.util.concurrent.TimeUnit;

public class Milliseconds {

public static void main(String[] args) {
    long milliseconds = 1000000;

    // long minutes = (milliseconds / 1000) / 60;
    long minutes = TimeUnit.MILLISECONDS.toMinutes(milliseconds);

    // long seconds = (milliseconds / 1000);
    long seconds = TimeUnit.MILLISECONDS.toSeconds(milliseconds);

    System.out.format("%d Milliseconds = %d minutes\n", milliseconds, minutes );
    System.out.println("Or");
    System.out.format("%d Milliseconds = %d seconds", milliseconds, seconds );

}
}

I found this program here "Link" there it is explained in detail.

Also, if you don't have the gradlew file in your current directory:

You can install gradle with homebrew with the following command:

$ brew install gradle

As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

$ gradle test 

TimezoneDb provides a free API: http://timezonedb.com/api

GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.

You can use Greenwich, UK if you'd like GMT.

There are actually two places where you need to change to row height, first the cell (you already did change that) and now select the Table View and check the Size Inspector

or you can't create function in loop

• such as

  for($i=1; $i<5; $i++) { function foo() { echo 'something'; } }

foo();
//It will show error regarding redeclaration

To get current fragment - get position in ViewPager at public void onPageSelected(final int position), and then

public PlaceholderFragment getFragmentByPosition(Integer pos){
    for(Fragment f:getChildFragmentManager().getFragments()){
        if(f.getId()==R.viewpager && f.getArguments().getInt("SECTNUM") - 1 == pos) {
            return (PlaceholderFragment) f;
        }
    }
    return null;
}

SECTNUM - position argument assigned in public static PlaceholderFragment newInstance(int sectionNumber); of Fragment

getChildFragmentManager() or getFragmentManager() - depends on how created SectionsPagerAdapter

use

$(this).cssUnit('marginBottom');

which return an array. first index returns margin bottom's value(example 20 for 20px) and second index returns margin bottom's unit(example px for 20px)

Yes, according to HTML5 drafts you can use the pattern attribute to specify the allowed input using a regular expression. For some types of data, you can use special input fields like <input type=email>. But these features still widely lack support or have qualitatively poor support.

Update: The site below is no longer running because, as they say on the site:

As of January 1, 2016, no publicly trusted CA is allowed to issue a SHA-1 certificate. In addition, SHA-1 support was removed by most modern browsers and operating systems in early 2017. Any new certificate you get should automatically use a SHA-2 algorithm for its signature.

Legacy clients will continue to accept SHA-1 certificates, and it is possible to have requested a certificate on December 31, 2015 that is valid for 39 months. So, it is possible to see SHA-1 certificates in the wild that expire in early 2019.

        draw(context, rect)
        
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image!
    }
}

Or you can use the command line below from version 4.4.x.

conda config --set proxy_servers.http http://id:pw@address:port
conda config --set proxy_servers.https https://id:pw@address:port

I also recommend using Joda as mentioned before.

Solving your problem using standard Java Date objects only can be done as follows:

    // **** YOUR CODE **** BEGIN ****
    long ts = System.currentTimeMillis();
    Date localTime = new Date(ts);
    String format = "yyyy/MM/dd HH:mm:ss";
    SimpleDateFormat sdf = new SimpleDateFormat(format);

    // Convert Local Time to UTC (Works Fine)
    sdf.setTimeZone(TimeZone.getTimeZone("UTC"));

Set "VM options" like: "-cp $Classpath$;your_classpath"

Basically you are positioning the cursor before the first row and then requesting data. You need to move the cursor to the first row.

 result.next();
 String foundType = result.getString(1);

It is common to do this in an if statement or loop.

if(result.next()){
   foundType = result.getString(1);
}

I had the same error when multiline string included new line (\n) characters. Merging all lines into one (thus removing all new line characters) and sending it to a browser used to solve. But was very inconvenient to code.

Often could not understand why this was an issue in Chrome until I came across to a statement which said that the current version of JavaScript engine in Chrome doesn't support multiline strings which are wrapped in single quotes and have new line (\n) characters in them. To make it work, multiline string need to be wrapped in double quotes. Changing my code to this, resolved this issue.

I will try to find a reference to a standard or Chrome doc which proves this. Until then, try this solution and see if works for you as well.

Code for any Browser:

function focusCampo(id){
    var inputField = document.getElementById(id);
    if (inputField != null && inputField.value.length != 0){
        if (inputField.createTextRange){
            var FieldRange = inputField.createTextRange();
            FieldRange.moveStart('character',inputField.value.length);
            FieldRange.collapse();
            FieldRange.select();
        }else if (inputField.selectionStart || inputField.selectionStart == '0') {
            var elemLen = inputField.value.length;
            inputField.selectionStart = elemLen;
            inputField.selectionEnd = elemLen;
            inputField.focus();
        }
    }else{
        inputField.focus();
    }
}

read does not export the variable (which is a good thing most of the time). Here's an alternative which can be exported in one command, can preserve or discard linefeeds, and allows mixing of quoting-styles as needed. Works for bash and zsh.

oneLine=$(printf %s \
    a   \
    " b "   \
    $'\tc\t'    \
    'd '    \
)
multiLine=$(printf '%s\n' \
    a   \
    " b "   \
    $'\tc\t'    \
    'd '    \
)

I admit the need for quoting makes this ugly for SQL, but it answers the (more generally expressed) question in the title.

I use it like this

export LS_COLORS=$(printf %s    \
    ':*rc=36:*.ini=36:*.inf=36:*.cfg=36:*~=33:*.bak=33:*$=33'   \
    ...
    ':bd=40;33;1:cd=40;33;1:or=1;31:mi=31:ex=00')

in a file sourced from both my .bashrc and .zshrc.

Use par(las=1).

See ?par:

las
numeric in {0,1,2,3}; the style of axis labels.
0: always parallel to the axis [default],
1: always horizontal,
2: always perpendicular to the axis,
3: always vertical.

you have to add fulltext index on specific fields you want to search.

ALTER TABLE news ADD FULLTEXT(headline, story);

where "news" is your table and "headline, story" fields you wont to enable for fulltext search

The best way would be to use the unslick setting or function(depending on your version of slick) as stated in the other answers but that did not work for me. I'm getting some errors from slick that seem to be related to this.

What did work for now, however, is removing the slick-initialized and slick-slider classes from the container before reinitializing slick, like so:

function slickCarousel() {
    $('.skills_section').removeClass("slick-initialized slick-slider");
    $('.skills_section').slick({
        infinite: true,
        slidesToShow: 3,
        slidesToScroll: 1
    });
}

Removing the classes doesn't seem to initiate the destroy event(not tested but makes sense) but does cause the later slick() call to behave properly so as long as you don't have any triggers on destroy, you should be good.

"One last remark: you should avoid using Task.Result and Task.Wait as much as possible as they always encapsulate the inner exception in an AggregateException and replace the message by a generic one (One or more errors occurred), which makes debugging harder. Even if the synchronous version shouldn't be used that often, you should strongly consider using Task.GetAwaiter().GetResult() instead."

MySQL implicitly closed the database connection because the connection has been inactive for too long (34,247,052 milliseconds ˜ 9.5 hours). If your program then fetches a bad connection from the connection-pool that causes the MySQLNonTransientConnectionException: No operations allowed after connection closed.

MySQL suggests:

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property autoReconnect=true to avoid this problem.

If you are producing the entire output yourself, you can use sprintf(), e.g.

> sprintf("%.10f",0.25)
[1] "0.2500000000"

specifies that you want to format a floating point number with ten decimal points (in %.10f the f is for float and the .10 specifies ten decimal points).

I don't know of any way of forcing R's higher level functions to print an exact number of digits.

Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.

Cut first two characters from string:

$ string="1234567890"; echo "${string:2}"
34567890

You can use Singleton when implementing the State pattern (in the manner shown in the GoF book). This is because the concrete State classes have no state of their own, and perform their actions in terms of a context class.

You can also make Abstract Factory a singleton.

Starting with Python 2.6, there is now ast.literal_eval:

>>> import ast
>>> help(ast.literal_eval)
Help on function literal_eval in module ast:

literal_eval(node_or_string)

    expression.  The string or node provided may only consist of the following

Which seems to work, as long as you're sure your strings are going to be either "True" or "False":

>>> ast.literal_eval("True")

I wouldn't normally recommend this, but it is completely built-in and could be the right thing depending on your requirements.

You need to set the password for root@localhost to be blank. There are two ways:

1. The MySQL SET PASSWORD command:

   SET PASSWORD FOR root@localhost=PASSWORD('');
   

2. Using the command-line mysqladmin tool:

   mysqladmin -u root -pType_in_your_current_password_here password ''
   

In UIKit, there are additions to the NSString class to get from a given NSString object the size it'll take up when rendered in a certain font.

Docs was here. Now it's here under Deprecated.

In short, if you go:

CGSize stringsize = [myString sizeWithFont:[UIFont systemFontOfSize:14]]; 
//or whatever font you're using
[button setFrame:CGRectMake(10,0,stringsize.width, stringsize.height)];

...you'll have set the button's frame to the height and width of the string you're rendering.

You'll probably want to experiment with some buffer space around that CGSize, but you'll be starting in the right place.

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

In addition other guys answer, its Easy to get property value of any object by use Extension method like:

public static class Helper
    {
        public static object GetPropertyValue(this object T, string PropName)
        {
            return T.GetType().GetProperty(PropName) == null ? null : T.GetType().GetProperty(PropName).GetValue(T, null);
        }

    }

Usage is:

Car foo = new Car();
var balbal = foo.GetPropertyValue("Make");

• From the Team Explorer menu click "add" under the Git repository section (you'll need to add the solution directory to the Local Git Repository)
• Open the solution from Team Explorer (right click on the added solution - open)
• Click on the commit button and look for the link "push"

Visual Studio should now ask your GitHub credentials and then proceed to upload your solution.

Since I have my Windows account connected to Visual Studio to work with Team Foundation I don't know if it works without an account, Visual Studio will keep track of who commits so if you are not logged in it will probably ask you to first.

What does return; mean?

return; really means it returns nothing void. That's it.

why return; or other codes can write below the statement of System.exit(0);

It is allowed since compiler doesn't know calling System.exit(0) will terminate the JVM. The compiler will just give a warning - unnecessary return statement

Why do you need to do this in one monster-regex? You can use actual code to implement some of these rules, and doing so would be much easier to modify if those requirements change later.

For example:

if(/^[A-Z0-9\s]*$/)
    # sentence is all uppercase, so just fail out
    return 0;

# Carry on with matching uppercase terms

Actually, it is worth noticing that git merge --abort is only equivalent to git reset --merge given that MERGE_HEAD is present. This can be read in the git help for merge command.

git merge --abort # is equivalent to git reset --merge when MERGE_HEAD is present.

After a failed merge, when there is no MERGE_HEAD, the failed merge can be undone with git reset --merge but not necessarily with git merge --abort, so they are not only old and new syntax for the same thing.

Personally I find git reset --merge much more useful in everyday work.

The second method, Task.Run, has been introduced in a later version of the .NET framework (in .NET 4.5).

However, the first method, Task.Factory.StartNew, gives you the opportunity to define a lot of useful things about the thread you want to create, while Task.Run doesn't provide this.

For instance, lets say that you want to create a long running task thread. If a thread of the thread pool is going to be used for this task, then this could be considered an abuse of the thread pool.

One thing you could do in order to avoid this would be to run the task in a separate thread. A newly created thread that would be dedicated to this task and would be destroyed once your task would have been completed. You cannot achieve this with the Task.Run, while you can do so with the Task.Factory.StartNew, like below:

Task.Factory.StartNew(..., TaskCreationOptions.LongRunning);

As it is stated here:

So, in the .NET Framework 4.5 Developer Preview, we’ve introduced the new Task.Run method. This in no way obsoletes Task.Factory.StartNew, but rather should simply be thought of as a quick way to use Task.Factory.StartNew without needing to specify a bunch of parameters. It’s a shortcut. In fact, Task.Run is actually implemented in terms of the same logic used for Task.Factory.StartNew, just passing in some default parameters. When you pass an Action to Task.Run:

Task.Run(someAction);

that’s exactly equivalent to:

Task.Factory.StartNew(someAction, 
    CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);

This happend due to default port 80 is blocked for Apache. You need to change the port or make the port accesible.

Go to your Apache configuration (httpd.conf) file in the Apache installation.

Find these lines:

#

Listen 192.168.1.2:80

Listen 80

#

Here 192.168.1.2 is my private IP address. Change it according to yours.

Change as below

Listen 192.168.1.2:8081

Listen 8081

Now when you access localhost you have to add the port explicitily as http://localhost:8081/...

• Go to the Build Path settings in the project properties. Windows -> Preferences -> Java Compiler
• Remove the JRE System Library
• Add another JRE with a "perfect match"
• clean and build your project again. It worked for me.

There are two ways to escaping the single quote in JavaScript.

1- Use double-quote or backticks to enclose the string.

Example: "fsdsd'4565sd" or `fsdsd'4565sd`.

2- Use backslash before any special character, In our case is the single quote

Example:strInputString = strInputString.replace(/ ' /g, " \\' ");

Note: use a double backslash.

Both methods work for me.

move does not make sense for a hashmap since its a dictionary with a hashcode for bucketing based on key and then a linked list for colliding hashcodes resolved via equals. Use a TreeMap for sorted maps and then pass in a custom comparator.

I am using lambda with Zappa; I am sending data with POST in json format:

My code for basic_lambda_pure.py is:

    print("Received event: " + json.dumps(event, indent=2))

    print("Request ID:", context.aws_request_id)
    print("Mem. limits(MB):", context.memory_limit_in_mb)
    # Code will execute quickly, so we add a 1 second intentional delay so you can see that in time remaining value.
    print("Time remaining (MS):", context.get_remaining_time_in_millis())

    if event["httpMethod"] == "GET":
        hub_mode = event["queryStringParameters"]["hub.mode"]

Drupal 8

Drupal 8 does not include JS-libraries to pages automaticly. So most probably if you meet this error you need to attach 'core/jquery.form' library to your page (or form). Add something like this to your render array:

$form['#attached']['library'][] = 'core/jquery.form';

When trying to distribute an npm package you should avoid using dependencies. Instead you need to consider adding it into peerDependencies or remove it from dependencies.

I dump my output to a text file. I then open it in notepad ++ then click the show all characters button. Not very elegant but it works.

Would you be happy to make "my file.xls" active if it didn't affect the screen? Turning off screen updating is the way to achieve this, it also has performance improvements (significant if you are doing looping while switching around worksheets / workbooks).

The command to do this is:

    Application.ScreenUpdating = False

Don't forget to turn it back to True when your macros is finished.

Yet another way to do this:

(Get-Date).AddDays(-1).Date.AddHours(22)

I usually do something along the lines of:

<View style={this.jewelStyle()} />

...

jewelStyle = function(options) {
   return {
     borderRadius: 12,
     background: randomColor(),
   }
 }

Every time View is rendered, a new style object will be instantiated with a random color associated with it. Of course, this means that the colors will change every time the component is re-rendered, which is perhaps not what you want. Instead, you could do something like this:

var myColor = randomColor()
<View style={jewelStyle(myColor)} />

...

jewelStyle = function(myColor) {
   return {
     borderRadius: 10,
     background: myColor,
   }
 }

Ideally, a hashtable is O(1). The problem is if two keys are not equal, however they result in the same hash.

For example, imagine the strings "it was the best of times it was the worst of times" and "Green Eggs and Ham" both resulted in a hash value of 123.

When the first string is inserted, it's put in bucket 123. When the second string is inserted, it would see that a value already exists for bucket 123. It would then compare the new value to the existing value, and see they are not equal. In this case, an array or linked list is created for that key. At this point, retrieving this value becomes O(n) as the hashtable needs to iterate through each value in that bucket to find the desired one.

For this reason, when using a hash table, it's important to use a key with a really good hash function that's both fast and doesn't often result in duplicate values for different objects.

Make sense?

Parent: Car
Child: Figo
Car c1 = new Figo();

=====
Upcasting:-
Method: Object c1 will refer to Methods of Class (Figo - Method must be overridden) because class "Figo" is specified with "new".
Instance Variable: Object c1 will refer to instance variable of Declaration Class ("Car").

When Declaration class is parent and object is created of child then implicit casting happens which is "Upcasting".

======
Downcasting:-
Figo f1 = (Figo) c1; //
Method: Object f1 will refer to Method of Class (figo) as initial object c1 is created with class "Figo". but once down casting is done, methods which are only present in class "Figo" can also be referred by variable f1.
Instance Variable: Object f1 will not refer to instance variable of Declaration class of object c1 (declaration class for c1 is CAR) but with down casting it will refer to instance variables of class Figo.

======
Use: When Object is of Child Class and declaration class is Parent and Child class wants to access Instance variable of it's own class and not of parent class then it can be done with "Downcasting".

I used a variation of Dunni solution above, but that particular code didn't work for me. In particular, when trying to use the Paint object set to have the traits of the view's Paint object, and then calling measureText(), it doesn't return the same value as directly calling the view's Paint object. Perhaps there are some differences in the way my views are set up that make the behavior different.

My solution was to directly use the view's Paint, even though there might be some performance penalties in changing the font size for the view multiple times.

From Xcode you can do it easily. Follow the steps from xcode. Drage visual effect view on your uiview or imageview.

Happy Coding :)

While the final version of HttpContent and the entire System.Net.Http namespace will come with .NET 4.5, you can use a .NET 4 version by adding the Microsoft.Net.Http package from NuGet

The Flexible does the trick

new Container(
       child: Row(
         children: <Widget>[
            Flexible(
               child: new Text("A looooooooooooooooooong text"))
                ],
        ));

This is the official doc https://flutter.dev/docs/development/ui/layout#lay-out-multiple-widgets-vertically-and-horizontally on how to arrange widgets.

Remember that Flexible and also Expanded, should only be used within a Column, Row or Flex, because of the Incorrect use of ParentDataWidget.

The solution is not the mere Flexible

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

I ran into this same problem last weekend when I needed to use cx_Oracle. After spending a lot of time trying to modify the LD_LIBRARY_PATH variable to include the $ORACLE_HOME/lib directoy, where libclntsh.so resides, I ended up solving the problem by creating symbolic links from all the Oracle xlibx.so libraries into /lib/xlibx.so. This certainly isn't the "cleanest" solution, but it has a good chance of working without causing too much trouble:

 cd $ORACLE_HOME/lib
 for f in `ls ./*.so*`; do;
   sudo ln -s $ORACLE_HOME/lib/$f /lib/$f 
 done

After I did that, cx_Oracle worked like a charm.

Remote scenario. But if you're trying to run tests in a rails app, and you get something like

"ActiveRecord::StatementInvalid: PG::ObjectInUse: ERROR: database "myapp_test" is being accessed by other users DETAIL: There is 1 other session using the database."

Make sure you close pgAdmin or any other postgres GUI tools before running tests.

@robertklep's answer to check socket.connected is correct except for reconnect event, https://socket.io/docs/client-api/#event-reconnect As the document said it is "Fired upon a successful reconnection." but when you check socket.connected then it is false.

Not sure it is a bug or intentional.

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.

The simplest method is probably functional inheritance but there are pros and cons.

You can use sets for this too

>>> a = {'x': 1, 'y': 2}
>>> b = {'y': 2, 'x': 1}
>>> set(a.iteritems())-set(b.iteritems())
set([])
>>> a['y']=3
>>> set(a.iteritems())-set(b.iteritems())
set([('y', 3)])
>>> set(b.iteritems())-set(a.iteritems())
set([('y', 2)])
>>> set(b.iteritems())^set(a.iteritems())
set([('y', 3), ('y', 2)])

You can reduce what they said in a few lines of code:

var nowPlusOneDay = moment().add('days', 1);
var nowPlusOneDayStr = nowPlusOneDay.format('YYYY-MM-DD');

alert('nowPlusOneDay Without Format(Unix Date):'+nowPlusOneDay);
alert('nowPlusOneDay Formatted(String):'+nowPlusOneDayStr);

I know this is an old post and has been answered many times. I too was wondering if JavaScript had a function that would do this. I was doing some math programming and needed to concatenate two numbers.

So the what if I needed to combine two numbers 17 and 29. Sure I can turn them into strings and concatenate them then turn the new string back into a number. That seems to work pretty well and I can go on with my code, but lets take a look here and try to figure out what is really happening here.

What are we doing to these two numbers, how do we take 17 and 29 and turn it into one thousand seven hundred and twenty-nine? Well we can multiply 17 by 100 then add 29. And how about 172 and 293 to get one hundred seventy-two thousand two hundred and ninety-three? Multiply 172 by 1000 and add 293. But what about only 2 and 9? Multiply 2 by 10 then add 9 to get 29.

So hopefully by now a pattern should be apparent to you. We can devise a math formula to do this calculation for us rather than just using strings. To concatenate any two numbers, a and b, we need to take the product of a and 10 to the power of length b then add b.

So how do we get the length of number b? Well, we could turn b into a string and get the length property of it.

    a * Math.pow(10, new String(b).length) + b;

But there has to be a better way to do this without strings, right? Yes there is.

For any two numbers, a and b, with any base B. We are going to multiply a by base B to the power of length b (using log base of b then flooring it to get the nearest whole number then adding 1 to it) then adding b.

So now our code looks like this:

    a * Math.pow(10, Math.floor(Math.log10(b)) + 1) + b;

But wait, what if I wanted to do this in base 2 or base 8? How can I do that? We can't use our formula that we just created with any other base but base 10. The JavaScript Math object already has built-in functions for base 10 and 2 (just Math.log), but how do we get log functions for any other base? We divide the log of b by the log of base. Math.log(b) / Math.log(base).

So now we have our fully functioning math based code for concatenating two numbers:

    function concatenate(a, b, base) {
        return a * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    }
    var a = 17, var b = 29;
    var concatenatedNumber = concatenate(a, b, 10);
    // concatenatedNumber = 1729

If you knew you were only going to be doing base 10 math, you could add a check for base is undefined then set base = 10:

    function concatenate(a, b, base) {
        if(typeof base == 'undefined') {
            base = 10;
        }
        return a * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    }

    var a = 17, b = 29;
    var newNumber = concatenate(a, b); // notice I did not use the base argument
    // newNumber = 1729

To make it easier for me, I used the prototype to add the function to the Number object:

    Number.prototype.concatenate = function(b, base) {
        if(typeof base == 'undefined') {
                base = 10;
        }
        return this * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    };
    var a = 17;
    var newNumber = a.concatenate(29);
    // newNumber = 1729

Tie::File is what you need:

Synopsis

# This file documents Tie::File version 0.98
use Tie::File;

tie @array, 'Tie::File', 'filename' or die ...;

$array[13] = 'blah';     # line 13 of the file is now 'blah'
print $array[42];        # display line 42 of the file

$n_recs = @array;        # how many records are in the file?
$#array -= 2;            # chop two records off the end


for (@array) {
  s/PERL/Perl/g;         # Replace PERL with Perl everywhere in the file
}

# These are just like regular push, pop, unshift, shift, and splice
# Except that they modify the file in the way you would expect

push @array, new recs...;
my $r1 = pop @array;
unshift @array, new recs...;
my $r2 = shift @array;
@old_recs = splice @array, 3, 7, new recs...;

untie @array;            # all finished

This will split it differently to what you have, but is still quite a nice list structure I think:

chunk.2 <- function(x, n, force.number.of.groups = TRUE, len = length(x), groups = trunc(len/n), overflow = len%%n) { 
  if(force.number.of.groups) {
    f1 <- as.character(sort(rep(1:n, groups)))
    f <- as.character(c(f1, rep(n, overflow)))
  } else {
    f1 <- as.character(sort(rep(1:groups, n)))
    f <- as.character(c(f1, rep("overflow", overflow)))
  }
  
  g <- split(x, f)
  
  if(force.number.of.groups) {
    g.names <- names(g)
    g.names.ordered <- as.character(sort(as.numeric(g.names)))
  } else {
    g.names <- names(g[-length(g)])
    g.names.ordered <- as.character(sort(as.numeric(g.names)))
    g.names.ordered <- c(g.names.ordered, "overflow")
  }
  
  return(g[g.names.ordered])
}

Which will give you the following, depending on how you want it formatted:

> x <- 1:10; n <- 3
> chunk.2(x, n, force.number.of.groups = FALSE)
$`1`
[1] 1 2 3

$`2`
[1] 4 5 6

$`3`
[1] 7 8 9

$overflow
[1] 10

> chunk.2(x, n, force.number.of.groups = TRUE)
$`1`
[1] 1 2 3

$`2`
[1] 4 5 6

$`3`
[1]  7  8  9 10

Running a couple of timings using these settings:

set.seed(42)
x <- rnorm(1:1e7)
n <- 3

Then we have the following results:

> system.time(chunk(x, n)) # your function 
   user  system elapsed 
 29.500   0.620  30.125 

> system.time(chunk.2(x, n, force.number.of.groups = TRUE))
   user  system elapsed 
  5.360   0.300   5.663 

Note: Changing as.factor() to as.character() made my function twice as fast.

Related to Eugen's answer, you can solve this particular case by creating a wrapper POJO object that contains a Collection<COrder> as its member variable. This will properly guide Jackson to place the actual Collection data inside the POJO's member variable and produce the JSON you are looking for in the API request.

Example:

public class ApiRequest {

   @JsonProperty("collection")
   private Collection<COrder> collection;

   // getters
}

Then set the parameter type of COrderRestService.postOrder() to be your new ApiRequest wrapper POJO instead of Collection<COrder>.

This will work:

if 'A' in df:

But for clarity, I'd probably write it as:

if 'A' in df.columns:

DataTable's Select method only supports simple filtering expressions like {field} = {value}. It does not support complex expressions, let alone SQL/Linq statements.

You can, however, use Linq extension methods to extract a collection of DataRows then create a new DataTable.

dt = dt.AsEnumerable()
       .GroupBy(r => new {Col1 = r["Col1"], Col2 = r["Col2"]})
       .Select(g => g.OrderBy(r => r["PK"]).First())
       .CopyToDataTable();

Regex

   $words = preg_replace('#[0-9 ]*#', '', $words);

From this paper: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2049.pdf

for( type-speci?er-seq simple-declarator : expression ) statement

is syntactically equivalent to

{
    typedef decltype(expression) C;
    auto&& rng(expression);
    for (auto begin(std::For<C>::begin(rng)), end(std::For<C>::end(rng)); begin != end; ++ begin) {
        type-speci?er-seq simple-declarator(*begin);
        statement
    }
}

So you can clearly see that what is abc in your case will be std::pair<key_type, value_type >. So for printing you can do access each element by abc.first and abc.second

It seems you're actually talking about an MVC (Model-View-Controller) pattern, where logic is separated into various "tiers". Django, as a framework, follows MVC (loosely). You have models that contain your business logic and relate directly to tables in your database, views which in effect act like the controller, handling requests and returning responses, and finally, templates which handle presentation.

Django isn't just one of these, it is a complete framework for application development and provides all the tools you need for that purpose.

Frontend vs Backend is all semantics. You could potentially build a Django app that is entirely "backend", using its built-in admin contrib package to manage the data for an entirely separate application. Or, you could use it solely for "frontend", just using its views and templates but using something else entirely to manage the data. Most usually, it's used for both. The built-in admin (the "backend"), provides an easy way to manage your data and you build apps within Django to present that data in various ways. However, if you were so inclined, you could also create your own "backend" in Django. You're not forced to use the default admin.

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761

jQuery

$(function() {
    $("td[colspan=3]").find("div").hide();
    $("tr").click(function(event) {
        var $target = $(event.target);
        $target.closest("tr").next().find("div").slideToggle();                
    });
});

HTML

<table>
    <thead>
        <tr>
            <th>one</th><th>two</th><th>three</th>
        </tr>
    </thead>
    <tbody>

        <tr>
            <td><p>data<p></td><td>data</td><td>data</td>
        </tr>
        <tr>
            <td colspan="3">
                <div>
                    <table>
                            <tr>
                                <td>data</td><td>data</td>
                            </tr>
                    </table>
                </div>
            </td>
        </tr>
    </tbody>
</table>

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable

To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.

I also made some minor changes to HTML and corresponding jQuery.

NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

First, you use include_directories() to tell CMake to add the directory as -I to the compilation command line. Second, you list the headers in your add_executable() or add_library() call.

As an example, if your project's sources are in src, and you need headers from include, you could do it like this:

include_directories(include)

add_executable(MyExec
  src/main.c
  src/other_source.c
  include/header1.h
  include/header2.h
)

From version 4.x, only Android SDK 24+ is supported by default, and androidx is required.

Add the following to your build.gradle file:

repositories {
    jcenter()
}

dependencies {
    implementation 'com.journeyapps:zxing-android-embedded:4.1.0'
    implementation 'androidx.appcompat:appcompat:1.0.2'
}

android {
    buildToolsVersion '28.0.3' // Older versions may give compile errors
}

Older SDK versions

For Android SDK versions < 24, you can downgrade zxing:core to 3.3.0 or earlier for Android 14+ support:

repositories {
    jcenter()
}

dependencies {
    implementation('com.journeyapps:zxing-android-embedded:4.1.0') { transitive = false }
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.zxing:core:3.3.0'
}

android {
    buildToolsVersion '28.0.3'
}

You'll also need this in your Android manifest:

<uses-sdk tools:overrideLibrary="com.google.zxing.client.android" />

I'm Using Xampp and Laravel 5.8 in Windows 10, and i've been like this before. When i got this problem, My XAMPP is no have Password Then I tried to delete some codes in config>database.php

'password' => env('DB_PASSWORD', ''),

And in .env

DB_PASSWORD=SECRET

the Problem is solved

I thought it would be beneficial to include what I consider to be a more simple method using numpy's linspace coupled with matplotlib's cm-type object. It's possible that the above solution is for an older version. I am using the python 3.4.3, matplotlib 1.4.3, and numpy 1.9.3., and my solution is as follows.

import matplotlib.pyplot as plt

from matplotlib import cm
from numpy import linspace

start = 0.0
stop = 1.0
number_of_lines= 1000
cm_subsection = linspace(start, stop, number_of_lines) 

colors = [ cm.jet(x) for x in cm_subsection ]

for i, color in enumerate(colors):
    plt.axhline(i, color=color)

plt.ylabel('Line Number')
plt.show()

This results in 1000 uniquely-colored lines that span the entire cm.jet colormap as pictured below. If you run this script you'll find that you can zoom in on the individual lines.

Now say I want my 1000 line colors to just span the greenish portion between lines 400 to 600. I simply change my start and stop values to 0.4 and 0.6 and this results in using only 20% of the cm.jet color map between 0.4 and 0.6.

So in a one line summary you can create a list of rgba colors from a matplotlib.cm colormap accordingly:

colors = [ cm.jet(x) for x in linspace(start, stop, number_of_lines) ]

In this case I use the commonly invoked map named jet but you can find the complete list of colormaps available in your matplotlib version by invoking:

>>> from matplotlib import cm
>>> dir(cm)

I think you did like this:

<asp:Content ID="Content2" ContentPlaceHolderID="MasterContent" runat="server">
  <form id="form1" runat="server">

 </form>
</asp:Content>

The form tag isn't needed. because you already have the same tag in the master page.

So you just remove that and it should be working.

Regarding [Console]::WriteLine() - you should use it if you are going to use pipelines in CMD (not in powershell). Say you want your ps1 to stream a lot of data to stdout, and some other utility to consume/transform it. If you use Write-Host in the script it will be much slower.

You can use sdp size unit instead of dp size unit. The sdp size unit is relative to the screen size and therefor is often preferred for targeting multiple screen sizes.

Use it carefully! for example, in most cases you still need to design a different layout for tablets.

Change your import in test.py to:

from .hello import hello1

I had to implement a year diff function which works similarly to sybase datediff. In that case the real year difference is counted, not the rounded day difference. So if there are two dates separated by one day, the year difference can be 1 (see select datediff(year, '20141231', '20150101')).

If the year diff has to be counted this way then use:

EXTRACT(YEAR FROM date_to) - EXTRACT(YEAR FROM date_from)

Just for the log the (almost) complete datediff function:

CREATE OR REPLACE FUNCTION datediff (datepart IN VARCHAR2, date_from IN DATE, date_to IN DATE)
RETURN NUMBER
AS
  diff NUMBER;
BEGIN
  diff :=  CASE datepart
    WHEN 'day'   THEN TRUNC(date_to,'DD') - TRUNC(date_from, 'DD')
    WHEN 'week'  THEN (TRUNC(date_to,'DAY') - TRUNC(date_from, 'DAY')) / 7
    WHEN 'month' THEN MONTHS_BETWEEN(TRUNC(date_to, 'MONTH'), TRUNC(date_from, 'MONTH'))
    WHEN 'year'  THEN EXTRACT(YEAR FROM date_to) - EXTRACT(YEAR FROM date_from)
  END;
  RETURN diff;
END;";

$ ip route show default | awk '/default/ {print $5}'

Here's a vectorized approach (assuming the dataframe, data_set to be defined as df instead) that returns a list of tuples as shown:

>>> df.set_index(['data_date'])[['data_1', 'data_2']].to_records().tolist()

produces:

[(datetime.datetime(2012, 2, 17, 0, 0), 24.75, 25.03),
 (datetime.datetime(2012, 2, 16, 0, 0), 25.0, 25.07),
 (datetime.datetime(2012, 2, 15, 0, 0), 24.99, 25.15),
 (datetime.datetime(2012, 2, 14, 0, 0), 24.68, 25.05),
 (datetime.datetime(2012, 2, 13, 0, 0), 24.62, 24.77),
 (datetime.datetime(2012, 2, 10, 0, 0), 24.38, 24.61)]

The idea of setting datetime column as the index axis is to aid in the conversion of the Timestamp value to it's corresponding datetime.datetime format equivalent by making use of the convert_datetime64 argument in DF.to_records which does so for a DateTimeIndex dataframe.

This returns a recarray which could be then made to return a list using .tolist

More generalized solution depending on the use case would be:

df.to_records().tolist()                              # Supply index=False to exclude index

This issue has occurred to me when I had a bad reference in my render/return statement. (point to a non existing class). Also check your return statement code for bad references.

This will do the trick

.gallery-item
{
  opacity:1;
}

.gallery-item:hover
{
  opacity:0;
  transition: opacity .2s ease-out;
  -moz-transition: opacity .2s ease-out;
  -webkit-transition: opacity .2s ease-out;
  -o-transition: opacity .2s ease-out;
}

You're looking for the FromBase64Transform class, used with the CryptoStream class.

If you have a string, you can also call Convert.FromBase64String.

I found applying the network and rebooting both the nodes did the trick for me.

kubectl apply -f [podnetwork].yaml

You could use OrderedDict (requires Python 2.7) or higher.

Also, note that OrderedDict({'a': 1, 'b':2, 'c':3}) won't work since the dict you create with {...} has already forgotten the order of the elements. Instead, you want to use OrderedDict([('a', 1), ('b', 2), ('c', 3)]).

As mentioned in the documentation, for versions lower than Python 2.7, you can use this recipe.

Do not use more than one style attribute. Just seperate styles in the style attribute with ; It is a block of inline CSS, so think of this as you would do CSS in a separate stylesheet.

So in this case its: style="height:100px;width:100px;"

You can use this for any CSS style, so if you wanted to change the colour of the text to white: style="height:100px;width:100px;color:#ffffff" and so on.

However, it is worth using inline CSS sparingly, as it can make code less manageable in future. Using an external stylesheet may be a better option for this. It depends really on your requirements. Inline CSS does make for quicker coding.

html of component:

<input [cdkTrapFocusAutoCapture]="show" [cdkTrapFocus]="show">

controler of component:

showSearch() {
  this.show = !this.show;    
}

..and do not forget about import A11yModule from @angular/cdk/a11y

import { A11yModule } from '@angular/cdk/a11y'

I have that little while earlier and solved it by following the steps provided below:

a. Right-click on the `External Libraries` and select the `Load/ Unload modules` button

b. If you see the modules are already loaded, perform the load/unload again. 

After I have done that, I see the project again in the top of the External Libraries section. I use Linux machine, BTW

Even though the question is quite fuzzy and the HTML snippet is quite limited, I suppose

.feature_desc {
    display: block;
}
.feature_desc:before {
    content: "";
    display: block;
}

might give you want you want to achieve without the <br/> element. Though it would help to see your CSS applied to these elements.

NOTE. The example above doesn't work in IE7 though.

Below is a simple way to convert dataframe column into numpy array.

df = pd.DataFrame(somedict) 
ytrain = df['label']
ytrain_numpy = np.array([x for x in ytrain['label']])

ytrain_numpy is a numpy array.

I tried with to.numpy() but it gave me the below error: TypeError: no supported conversion for types: (dtype('O'),) while doing Binary Relevance classfication using Linear SVC. to.numpy() was converting the dataFrame into numpy array but the inner element's data type was list because of which the above error was observed.

parseInt converts to a integer number, that is, it strips decimals. Number does not convert to integer.

To replace a character at a specified position :

public static String replaceCharAt(String s, int pos, char c) {
   return s.substring(0,pos) + c + s.substring(pos+1);
}

If you are using webjars. You need to add this in your configure method: http.authorizeRequests().antMatchers("/webjars/**").permitAll();

Make sure this is the first statement. For example:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/webjars/**").permitAll();
        http.authorizeRequests().anyRequest().authenticated();
         http.formLogin()

You will also need to have this in order to have webjars enabled:

@Configuration
    public class MvcConfig extends WebMvcConfigurerAdapter {
        ...
        @Override
        public void addResourceHandlers(ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
        ...
    }

You get a unix timestamp in C# by using DateTime.UtcNow and subtracting the epoch time of 1970-01-01.

e.g.

Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

DateTime.UtcNow can be replaced with any DateTime object that you would like to get the unix timestamp for.

There is also a field, DateTime.UnixEpoch, which is very poorly documented by MSFT, but may be a substitute for new DateTime(1970, 1, 1)

date = new DateTime(date.year, date.month, date.day, HH, MM, SS);

If you are Android developer you can use:

<pre class=”prettyprint”>

TODO:your code.

</pre>

To pretty print your code in Javadoc with Java code.

Sadly there are no operation-assignment operators in VBA.

(Addition-assignment += are available in VB.Net)

Pointless workaround;

Sub Inc(ByRef i As Integer)
   i = i + 1  
End Sub
...
Static value As Integer
inc value
inc value

For clarity, I thought that a direct example of grabbing onto a resource can be shown from the following that I think contributes to the response for this question with a quick direct example.

private MenuItem menuItem_;

@Override
public boolean onCreateOptionsMenu(Menu menuF) 
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_layout, menuF);
    menuItem_ = menuF.findItem(R.id.menu_item_identifier);
    return true;
}

In this case you hold onto a MenuItem reference at the beginning and then change the state of it (for icon state changes for example) at a later given point in time.

I managed to render the following SELECT with SQLAlchemy on both layers.

SELECT count(*) AS count_1
FROM "table"

Usage from the SQL Expression layer

from sqlalchemy import select, func, Integer, Table, Column, MetaData

metadata = MetaData()

table = Table("table", metadata,
              Column('primary_key', Integer),
              Column('other_column', Integer)  # just to illustrate
             )   

print select([func.count()]).select_from(table)

Usage from the ORM layer

You just subclass Query (you have probably anyway) and provide a specialized count() method, like this one.

from sqlalchemy.sql.expression import func

class BaseQuery(Query):
    def count_star(self):
        count_query = (self.statement.with_only_columns([func.count()])
                       .order_by(None))
        return self.session.execute(count_query).scalar()

Please note that order_by(None) resets the ordering of the query, which is irrelevant to the counting.

Using this method you can have a count(*) on any ORM Query, that will honor all the filter andjoin conditions already specified.
