Have you tried removing it from the DOM, then inserting it back again?

I just did, that doesn't work. However, creating a new script tag and copying the contents of the existing script tag, then adding it, works well.

See my example http://jsfiddle.net/mendesjuan/LPFYB/

var scriptTag = document.createElement('script');
scriptTag.innerText = "document.body.innerHTML += 'Here again ---<BR>';";
var head = document.getElementsByTagName('head')[0];
head.appendChild(scriptTag);

setInterval(function() {
    head.removeChild(scriptTag);
    var newScriptTag = document.createElement('script');
    newScriptTag.innerText = scriptTag.innerText;
    head.appendChild(newScriptTag);
    scriptTag = newScriptTag;    
}, 1000);

This won't work if you expect the script to change every time, which I believe is your case. You should follow Kelly's suggestion, just remove the old script tag (just to keep the DOM slim, it won't affect the outcome) and reinsert a new script tag with the same src, plus a cachebuster.

You could try this:

 $(".edgetoedge").children().removeClass("highlight");

James Curran succinctly says: "Switches based on integers can be optimized to very efficent code. Switches based on other data type can only be compiled to a series of if() statements. For that reason C & C++ only allow switches on integer types, since it was pointless with other types."

My opinion, and it's only that, is that as soon as you start switching on non-primitives you need to start thinking about "equals" versus "==". Firstly comparing two strings can be a fairly lengthy procedure, adding to the performance problems that are mentioned above. Secondly if there is switching on strings there will be demand for switching on strings ignoring case, switching on strings considering/ignoring locale,switching on strings based on regex.... I would approve of a decision that saved a lot of time for the language developers at the cost of a small amount of time for programmers.

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

Try this.

<%@page language="java" session="true" %>

Sorry for being that guy but AngularJS offers a simple and elegant solution.

Here is the code I use:

ngApp.controller('ngController', ['$upload',_x000D_
function($upload) {_x000D_
_x000D_
  $scope.Upload = function($files, index) {_x000D_
    for (var i = 0; i < $files.length; i++) {_x000D_
      var file = $files[i];_x000D_
      $scope.upload = $upload.upload({_x000D_
        file: file,_x000D_
        url: '/File/Upload',_x000D_
        data: {_x000D_
          id: 1 //some data you want to send along with the file,_x000D_
          name: 'ABC' //some data you want to send along with the file,_x000D_
        },_x000D_
_x000D_
      }).progress(function(evt) {_x000D_
_x000D_
      }).success(function(data, status, headers, config) {_x000D_
          alert('Upload done');_x000D_
        }_x000D_
      })_x000D_
    .error(function(message) {_x000D_
      alert('Upload failed');_x000D_
    });_x000D_
  }_x000D_
};_x000D_
}]);

.Hidden {_x000D_
  display: none_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_

  <input type="file" ng-file-select="Upload($files, 1)" class="Hidden" />_x000D_

On the server side I have an MVC controller with an action the saves the files uploaded found in the Request.Files collection and returning a JsonResult.

If you use AngularJS try this out, if you don't... sorry mate :-)

Try the following:

NextViewController *nextView = [self.storyboard instantiateViewControllerWithIdentifier:@"nextView"];
[self presentViewController:nextView animated:YES completion:NULL];

Replacing all zeroes to NA:

df[df == 0] <- NA

Explanation

1. It is not NULL what you should want to replace zeroes with. As it says in ?'NULL',

NULL represents the null object in R

which is unique and, I guess, can be seen as the most uninformative and empty object.¹ Then it becomes not so surprising that

data.frame(x = c(1, NULL, 2))
#   x
# 1 1
# 2 2

That is, R does not reserve any space for this null object.² Meanwhile, looking at ?'NA' we see that

NA is a logical constant of length 1 which contains a missing value indicator. NA can be coerced to any other vector type except raw.

Importantly, NA is of length 1 so that R reserves some space for it. E.g.,

data.frame(x = c(1, NA, 2))
#    x
# 1  1
# 2 NA
# 3  2

Also, the data frame structure requires all the columns to have the same number of elements so that there can be no "holes" (i.e., NULL values).

Now you could replace zeroes by NULL in a data frame in the sense of completely removing all the rows containing at least one zero. When using, e.g., var, cov, or cor, that is actually equivalent to first replacing zeroes with NA and setting the value of use as "complete.obs". Typically, however, this is unsatisfactory as it leads to extra information loss.

2. Instead of running some sort of loop, in the solution I use df == 0 vectorization. df == 0 returns (try it) a matrix of the same size as df, with the entries TRUE and FALSE. Further, we are also allowed to pass this matrix to the subsetting [...] (see ?'['). Lastly, while the result of df[df == 0] is perfectly intuitive, it may seem strange that df[df == 0] <- NA gives the desired effect. The assignment operator <- is indeed not always so smart and does not work in this way with some other objects, but it does so with data frames; see ?'<-'.

_{¹ The empty set in the set theory feels somehow related.
² Another similarity with the set theory: the empty set is a subset of every set, but we do not reserve any space for it.}

Only integral values (e.g., static const int ARRAYSIZE) are initialized in header file because they are usually used in class header to define something such as the size of an array. Non-integral values are initialized in implementation file.

When testing an element against :hidden selector in jQuery it should be considered that an absolute positioned element may be recognized as hidden although their child elements are visible.

This seems somewhat counter-intuitive in the first place – though having a closer look at the jQuery documentation gives the relevant information:

Elements can be considered hidden for several reasons: [...] Their width and height are explicitly set to 0. [...]

So this actually makes sense in regards to the box-model and the computed style for the element. Even if width and height are not set explicitly to 0 they may be set implicitly.

Have a look at the following example:

console.log($('.foo').is(':hidden')); // true_x000D_
console.log($('.bar').is(':hidden')); // false

.foo {_x000D_
  position: absolute;_x000D_
  left: 10px;_x000D_
  top: 10px;_x000D_
  background: #ff0000;_x000D_
}_x000D_
_x000D_
.bar {_x000D_
  position: absolute;_x000D_
  left: 10px;_x000D_
  top: 10px;_x000D_
  width: 20px;_x000D_
  height: 20px;_x000D_
  background: #0000ff;_x000D_
}

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

Update for jQuery 3.x:

With jQuery 3 the described behavior will change! Elements will be considered visible if they have any layout boxes, including those of zero width and/or height.

JSFiddle with jQuery 3.0.0-alpha1:

http://jsfiddle.net/pM2q3/7/

The same JavaScript code will then have this output:

console.log($('.foo').is(':hidden')); // false
console.log($('.bar').is(':hidden')); // false

I solved changing

readable_json['firstName']

by

readable_json[0]['firstName']

I experienced this error with Python2.7. It happened to me while trying to run many python programs, but I managed to reproduce it with this simple script:

#!/usr/bin/env python

import subprocess
import sys

result = subprocess.Popen([u'svn', u'info'])
if not callable(getattr(result, "__enter__", None)) and not callable(getattr(result, "__exit__", None)):
    print("foo")
print("bar")

On success, it should print out 'foo' and 'bar', and probably an error message if you're not in a svn folder.

On failure, it should print 'UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 39: ordinal not in range(128)'.

After trying to regenerate my locales and many other solutions posted in this question, I learned the error was happening because I had a special character (l) encoded in my PATH environment variable. After fixing the PATH in '~/.bashrc', and exiting my session and entering again, (apparently sourcing '~/.bashrc' didn't work), the issue was gone.

This is good for shallow cloning. The object spread is a standard part of ECMAScript 2018.

For deep cloning you'll need a different solution.

const clone = {...original} to shallow clone

const newobj = {...original, prop: newOne} to immutably add another prop to the original and store as a new object.

Can you provide an example of what did not work? As you likely know, the Wiring language is based on C/C++, however, not all of C++ is supported.

Whether you are allowed to create classes in the Wiring IDE, I'm not sure (my first Arduino is in the mail right now). I do know that if you wrote a C++ class, compiled it using AVR-GCC, then loaded it on your Arduino using AVRDUDE, it would work.

You must define states not equal to null..

@if (ViewBag.States!= null)
{
    @foreach (KeyValuePair<int, string> de in ViewBag.States)
    {
        value="@de.Key">@de.Value 
    }
}                                

This is a simple reiteration that can delete multiple values in the array.

    // Your array
    $list = array("apple", "orange", "strawberry", "lemon", "banana");

    // Initilize what to delete
    $delete_val = array("orange", "lemon", "banana");

    // Search for the array key and unset   
    foreach($delete_val as $key){
        $keyToDelete = array_search($key, $list);
        unset($list[$keyToDelete]);
    }

psxls gave a great answer but I think my Notepad++ version is slightly different so the $ (dollar sign) capturing did not work.

I have Notepad++ v.5.9.3 and here's how you can accomplish your task:

Search for the pattern: value=\"([0-9]*)\" And replace with: \1 (whatever you want to do around that capturing group)

Ex. Surround with square brackets

[\1] --> will produce value="[4]"

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

    let url = URL(string: urlStr)

    var request: URLRequest = URLRequest(url: url!)

    request.httpMethod = "POST"

    request.httpBody = bodyData

A general answer

select * from [dbo].[SplitString]('1,2',',') -- Will work

If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?

So, you are saying that the following two queries produce correct results:

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))

DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))

I made this generic state machine out of Juliet's code. It's working awesome for me.

These are the benefits:

• you can create new state machine in code with two enums TState and TCommand,
• added struct TransitionResult<TState> to have more control over the output results of [Try]GetNext() methods
• exposing nested class StateTransition only through AddTransition(TState, TCommand, TState) making it easier to work with it

Code:

public class StateMachine<TState, TCommand>
    where TState : struct, IConvertible, IComparable
    where TCommand : struct, IConvertible, IComparable
{
    protected class StateTransition<TS, TC>
        where TS : struct, IConvertible, IComparable
        where TC : struct, IConvertible, IComparable
    {
        readonly TS CurrentState;
        readonly TC Command;

        public StateTransition(TS currentState, TC command)
        {
            if (!typeof(TS).IsEnum || !typeof(TC).IsEnum)
            {
                throw new ArgumentException("TS,TC must be an enumerated type");
            }

            CurrentState = currentState;
            Command = command;
        }

        public override int GetHashCode()
        {
            return 17 + 31 * CurrentState.GetHashCode() + 31 * Command.GetHashCode();
        }

        public override bool Equals(object obj)
        {
            StateTransition<TS, TC> other = obj as StateTransition<TS, TC>;
            return other != null
                && this.CurrentState.CompareTo(other.CurrentState) == 0
                && this.Command.CompareTo(other.Command) == 0;
        }
    }

    private Dictionary<StateTransition<TState, TCommand>, TState> transitions;
    public TState CurrentState { get; private set; }

    protected StateMachine(TState initialState)
    {
        if (!typeof(TState).IsEnum || !typeof(TCommand).IsEnum)
        {
            throw new ArgumentException("TState,TCommand must be an enumerated type");
        }

        CurrentState = initialState;
        transitions = new Dictionary<StateTransition<TState, TCommand>, TState>();
    }

    /// <summary>
    /// Defines a new transition inside this state machine
    /// </summary>
    /// <param name="start">source state</param>
    /// <param name="command">transition condition</param>
    /// <param name="end">destination state</param>
    protected void AddTransition(TState start, TCommand command, TState end)
    {
        transitions.Add(new StateTransition<TState, TCommand>(start, command), end);
    }

    public TransitionResult<TState> TryGetNext(TCommand command)
    {
        StateTransition<TState, TCommand> transition = new StateTransition<TState, TCommand>(CurrentState, command);
        TState nextState;
        if (transitions.TryGetValue(transition, out nextState))
            return new TransitionResult<TState>(nextState, true);
        else
            return new TransitionResult<TState>(CurrentState, false);
    }

    public TransitionResult<TState> MoveNext(TCommand command)
    {
        var result = TryGetNext(command);
        if(result.IsValid)
        {
            //changes state
            CurrentState = result.NewState;
        }
        return result;
    }
}

This is the return type of TryGetNext method:

public struct TransitionResult<TState>
{
    public TransitionResult(TState newState, bool isValid)
    {
        NewState = newState;
        IsValid = isValid;
    }
    public TState NewState;
    public bool IsValid;
}

How to use:

This is how you can create a OnlineDiscountStateMachine from the generic class:

Define an enum OnlineDiscountState for its states and an enum OnlineDiscountCommand for its commands.

Define a class OnlineDiscountStateMachine derived from the generic class using those two enums

Derive the constructor from base(OnlineDiscountState.InitialState) so that the initial state is set to OnlineDiscountState.InitialState

Use AddTransition as many times as needed

public class OnlineDiscountStateMachine : StateMachine<OnlineDiscountState, OnlineDiscountCommand>
{
    public OnlineDiscountStateMachine() : base(OnlineDiscountState.Disconnected)
    {
        AddTransition(OnlineDiscountState.Disconnected, OnlineDiscountCommand.Connect, OnlineDiscountState.Connected);
        AddTransition(OnlineDiscountState.Disconnected, OnlineDiscountCommand.Connect, OnlineDiscountState.Error_AuthenticationError);
        AddTransition(OnlineDiscountState.Connected, OnlineDiscountCommand.Submit, OnlineDiscountState.WaitingForResponse);
        AddTransition(OnlineDiscountState.WaitingForResponse, OnlineDiscountCommand.DataReceived, OnlineDiscountState.Disconnected);
    }
}

use the derived state machine

    odsm = new OnlineDiscountStateMachine();
    public void Connect()
    {
        var result = odsm.TryGetNext(OnlineDiscountCommand.Connect);

        //is result valid?
        if (!result.IsValid)
            //if this happens you need to add transitions to the state machine
            //in this case result.NewState is the same as before
            Console.WriteLine("cannot navigate from this state using OnlineDiscountCommand.Connect");

        //the transition was successfull
        //show messages for new states
        else if(result.NewState == OnlineDiscountState.Error_AuthenticationError)
            Console.WriteLine("invalid user/pass");
        else if(result.NewState == OnlineDiscountState.Connected)
            Console.WriteLine("Connected");
        else
            Console.WriteLine("not implemented transition result for " + result.NewState);
    }

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

In short, the only reason to use UTF-16 or UTF-32 is to support non-English and ancient scripts respectively.

I was wondering why anyone would chose to have non-UTF-8 encoding when it is obviously more efficient for web/programming purposes.

A common misconception - the suffixed number is NOT an indication of its capability. They all support the complete Unicode, just that UTF-8 can handle ASCII with a single byte, so is MORE efficient/less corruptible to the CPU and over the internet.

Need Key & Value in Iteration

Use entrySet() to iterate through Map and need to access value and key:

Map<String, Person> hm = new HashMap<String, Person>();

hm.put("A", new Person("p1"));
hm.put("B", new Person("p2"));
hm.put("C", new Person("p3"));
hm.put("D", new Person("p4"));
hm.put("E", new Person("p5"));

Set<Map.Entry<String, Person>> set = hm.entrySet();

for (Map.Entry<String, Person> me : set) {
  System.out.println("Key :"+me.getKey() +" Name : "+ me.getValue().getName()+"Age :"+me.getValue().getAge());

}

Need Key in Iteration

If you want just to iterate over keys of map you can use keySet()

for(String key: map.keySet()) {
     Person value = map.get(key); 
}

Need Value in Iteration

If you just want to iterate over values of map you can use values()

for(Person person: map.values()) {

}

There's also AppGyver Steroids that unites PhoneGap and Native UI nicely.

With Steroids you can add things like native tabs, native navigation bar, native animations and transitions, native modal windows, native drawer/panel (facebooks side menu) etc. to your PhoneGap app.

Here's a demo: http://youtu.be/oXWwDMdoTCk?t=20m17s

Substring is probably what you want, as others pointed out. But just to add another option to the mix...

string result = string.Join(string.Empty, str.Skip(10));

You dont even need to check the length on this! :) If its less than 10 chars, you get an empty string.

Based on this blog post I was able to trigger hovering using the following code with Selenium 2 Webdriver:

String javaScript = "var evObj = document.createEvent('MouseEvents');" +
                    "evObj.initMouseEvent(\"mouseover\",true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);" +
                    "arguments[0].dispatchEvent(evObj);";


((JavascriptExecutor)driver).executeScript(javaScript, webElement);

I think the correct way to do is

brew upgrade mongodb

It will upgrade the mongodb formula. If you want to upgrade all outdated formula, simply

brew upgrade

From plt.imshow() official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 10000, 0, 10], aspect = 1000)

Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.

plt.imshow(data, origin = 'lower',  extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')

To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1] and y_max - y_min = y_res * data.shape[0], where extent = [x_min, x_max, y_min, y_max]. By default, aspect = 1, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower',  extent = [0, 5, 0, 5])

The aspect of color pixel is x_res / y_res. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.

data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.5)

The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.2)

Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

MySql decimal types are a little bit more complicated than just left-of and right-of the decimal point.

The first argument is precision, which is the number of total digits. The second argument is scale which is the maximum number of digits to the right of the decimal point.

Thus, (4,2) can be anything from -99.99 to 99.99.

As for why you're getting 99.99 instead of the desired 3.80, the value you're inserting must be interpreted as larger than 99.99, so the max value is used. Maybe you could post the code that you are using to insert or update the table.

Edit

Corrected a misunderstanding of the usage of scale and precision, per http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html.

I know this is an old question but just for the record this can also be done by passing appropriate connection options as arguments to the _mysql.connect call. For example,

con = _mysql.connect(host='localhost', user='dell-pc', passwd='', db='test',
          connect_timeout=1000)

Notice the use of keyword parameters (host, passwd, etc.). They improve the readability of your code.

For detail about different arguments that you can pass to _mysql.connect, see MySQLdb API documentation

Have you tried using @JsonProperty?

@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}

I have just faced the same problem. First, you need to install the appropriate Oracle client for your OS. In my case, to install it on Ubuntu x64 I have followed this instructions https://help.ubuntu.com/community/Oracle%20Instant%20Client#Install_RPMs

Then, you need to install cx_Oracle, a Python module to connect to the Oracle client. Again, assuming you are running Ubuntu in a 64bit machine, you should type in a shell:

wget -c http://prdownloads.sourceforge.net/cx-oracle/cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
sudo alien -i cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm

This will work for Oracle 11g if you have installed Python 2.7.x, but you can download a different cx_Oracle version in http://cx-oracle.sourceforge.net/ To check which Python version do you have, type in a terminal:

python -V

I hope it helps

Strings in python are immutable, so you cannot treat them as a list and assign to indices.

Use .replace() instead:

line = line.replace(';', ':')

If you need to replace only certain semicolons, you'll need to be more specific. You could use slicing to isolate the section of the string to replace in:

line = line[:10].replace(';', ':') + line[10:]

That'll replace all semi-colons in the first 10 characters of the string.

std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.

error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
 std::unique_ptr<int>]'

The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.

The following works with the new emplace calls.

std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );

See using unique_ptr with standard library containers for further reading.

In a relational database all types of relationships are represented in the same way: as relations. The candidate key(s) of each relation (and possibly other constraints as well) determine what kind of relationship is being represented. 1:n and m:n are two kinds of binary relationship:

C {Employee*,Company}
B {Book*,Author*}

In each case * designates the key attribute(s). {Book,Author} is a compound key.

C is a relation where each employee works for only one company but each company may have many employees (1:n): B is a relation where a book can have many authors and an author may write many books (m:n):

Notice that the key constraints ensure that each employee can only be associated with one company whereas any combination of books and authors is permitted.

Other kinds of relationship are possible as well: n-ary (having more than two components); fixed cardinality (m:n where m and n are fixed constants or ranges); directional; and so on. William Kent in his book "Data and Reality" identifies at least 432 kinds - and that's just for binary relationships. In practice, the binary relationships 1:n and m:n are very common and are usually singled out as specially important in designing and understanding data models.

You could instead, insert newline chars until everything gets scrolled, take a look here.

With that, you achieve portability easily.

This is a warning from distutils, and is a sign that you do not have setuptools installed. Installing it from http://pypi.python.org/pypi/setuptools will remove the warning.

here is a simple javascript for that

call this when you need to scroll the screen to an element which has id="yourSpecificElementId"

window.scroll(0,findPos(document.getElementById("yourSpecificElementId")));

and you need this function for the working:

//Finds y value of given object
function findPos(obj) {
    var curtop = 0;
    if (obj.offsetParent) {
        do {
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
    return [curtop];
    }
}

the screen will be scrolled to your specific element.

Run

service ssh restart

instead of

/etc/init.d/ssh restart

This might work.

// you can use this
List<Value> list = new ArrayList<Value>(map.values());

// or you may use 
List<Value> list = new ArrayList<Value>();
for (Map.Entry<String, String> entry : map.entrySet())
{
list.add(entry.getValue());    
}

We have two problems to cope with.

1. You cannot provide a sensible GetHashCode() if any field in the object can be changed. Also often a object will NEVER be used in a collection that depends on GetHashCode(). So the cost of implementing GetHashCode() is often not worth it, or it is not possible.

2. If someone puts your object in a collection that calls GetHashCode() and you have overrided Equals() without also making GetHashCode() behave in a correct way, that person may spend days tracking down the problem.

Therefore by default I do.

public class Foo
{
    public int FooId { get; set; }
    public string FooName { get; set; }

    public override bool Equals(object obj)
    {
        Foo fooItem = obj as Foo;

        if (fooItem == null)
        {
           return false;
        }

        return fooItem.FooId == this.FooId;
    }

    public override int GetHashCode()
    {
        // Some comment to explain if there is a real problem with providing GetHashCode() 
        // or if I just don't see a need for it for the given class
        throw new Exception("Sorry I don't know what GetHashCode should do for this class");
    }
}

Instead of 1:nrow(mydata_2) you can simply use the which() function: which(mydata_2[,4] == 1578)

Although as it was pointed out above, the 3rd column contains 1578, not the fourth: which(mydata_2[,3] == 1578)

You have two basic options provided by java.util.Collections:

• <T extends Comparable<? super T>> void sort(List<T> list)
  • Use this if T implements Comparable and you're fine with that natural ordering
• <T> void sort(List<T> list, Comparator<? super T> c)
  • Use this if you want to provide your own Comparator.

Depending on what the Collection is, you can also look at SortedSet or SortedMap.

grep -nr 'yourString*' .

The dot at the end searches the current directory. Meaning for each parameter:

-n            Show relative line number in the file
'yourString*' String for search, followed by a wildcard character
-r            Recursively search subdirectories listed
.             Directory for search (current directory)

grep -nr 'MobileAppSer*' . (Would find MobileAppServlet.java or MobileAppServlet.class or MobileAppServlet.txt; 'MobileAppASer*.*' is another way to do the same thing.)

To check more parameters use man grep command.

I have a very quick and simple workaround here, it does work for me, and no matter the event would be triggered once or twice or more times occasionally, check it out:

private int fireCount = 0;
private void inputFileWatcher_Changed(object sender, FileSystemEventArgs e)
    {
       fireCount++;
       if (fireCount == 1)
        {
            MessageBox.Show("Fired only once!!");
            dowork();
        }
        else
        {
            fireCount = 0;
        }
    }
}

Loading many classes can add some milliseconds to the start. If the startup isn't so critical and you are look at the efficiency of classes after startup there is no difference.

What you're asking for isn't impossible, but it's probably not what you actually want.

Instead of trying to save the screen output to a file, just write the output to a file instead of to the screen.

Like this:

with open('outfile.txt', 'w') as outfile:
    print >>outfile, 'Data collected on:', input['header']['timestamp'].date()

Just add that >>outfile into all your print statements, and make sure everything is indented under that with statement.

More generally, it's better to use string formatting rather than magic print commas, which means you can use the write function instead. For example:

outfile.write('Data collected on: {}'.format(input['header']['timestamp'].date()))

But if print is already doing what you want as far as formatting goes, you can stick with it for now.

What if you've got some Python script someone else wrote (or, worse, a compiled C program that you don't have the source to) and can't make this change? Then the answer is to wrap it in another script that captures its output, with the subprocess module. Again, you probably don't want that, but if you do:

output = subprocess.check_output([sys.executable, './otherscript.py'])
with open('outfile.txt', 'wb') as outfile:
    outfile.write(output)

I suspect you did not know that there are different & escapes in HTML. The W3C you can see the codes. &times means × in HTML code. Use &times instead.

This wikipedia article provides the formulae and an example. The text is in german, but the calculations speak for themselves.

Look at using the beautiful soup html parsing library.

http://www.crummy.com/software/BeautifulSoup/

You will do something like this:

import BeautifulSoup
soup = BeautifulSoup.BeautifulSoup(html)
for link in soup.findAll("a"):
    print link.get("href")

You can simply use this: \This is .*? \sentence

If you include a font file (otf, ttf, etc.) in your package, you can use the font in your application via the method described here:

Oracle Java SE 6: java.awt.Font

There is a tutorial available from Oracle that shows this example:

try {
     GraphicsEnvironment ge = 
         GraphicsEnvironment.getLocalGraphicsEnvironment();
     ge.registerFont(Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf")));
} catch (IOException|FontFormatException e) {
     //Handle exception
}

I would probably wrap this up in some sort of resource loader though as to not reload the file from the package every time you want to use it.

An answer more closely related to your original question would be to install the font as part of your application's installation process. That process will depend on the installation method you choose. If it's not a desktop app you'll have to look into the links provided.

I just had a problem like this. My particular problem was caused by a system crash that corrupted the most recent commit (and hence also the master branch). I hadn't pushed, and wanted to re-make that commit. In my particular case, I was able to deal with it like this:

1. Make a backup of .git/: rsync -a .git/ git-bak/
2. Check .git/logs/HEAD, and find the last line with a valid commit ID. For me, this was the second most recent commit. This was good, because I still had the working directory versions of the file, and so the every version I wanted.
3. Make a branch at that commit: git branch temp <commit-id>
4. re-do the broken commit with the files in the working directory.
5. git reset master temp to move the master branch to the new commit you made in step 2.
6. git checkout master and check that it looks right with git log.
7. git branch -d temp.
8. git fsck --full, and it should now be safe to delete any corrupted objects that fsck finds.
9. If it all looks good, try pushing. If that works,

That worked for for me. I suspect that this is a reasonably common scenario, since the most recent commit is the most likely one to be corrupted, but if you lose one further back, you can probably still use a method like this, with careful use of git cherrypick, and the reflog in .git/logs/HEAD.

This works for me:

ListBox x = new ListBox();
x.Items.Add(new ListItem("Hello", "1"));
x.Items.Add(new ListItem("Bye", "2"));

Console.Write(x.Items[0].Value);

If you're prepared to use a JDialog instead of a JFrame, you can set the ModalityType to APPLICATION_MODAL.

This provides identical behaviour to your typical JOptionPane:

import java.awt.event.ActionEvent;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;

public class MyDialog extends JFrame {

public MyDialog() {
    setBounds(300, 300, 300, 300);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setVisible(true);
    setLayout(new FlowLayout());
    JButton btn = new JButton("TEST");
    add(btn);
    btn.addActionListener(new ActionListener() 
    {

        @Override
        public void actionPerformed(ActionEvent e) {
            showDialog();
        }
    });
}

private void showDialog() 
{

    JDialog dialog = new JDialog(this, Dialog.ModalityType.APPLICATION_MODAL);
    //OR, you can do the following...
    //JDialog dialog = new JDialog();
    //dialog.setModalityType(Dialog.ModalityType.APPLICATION_MODAL);

    dialog.setBounds(350, 350, 200, 200);
    dialog.setVisible(true);
}

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

You could use a pseudo element for this, and have your image on a hover:

.image {_x000D_
  position: relative;_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_
  background: url(http://lorempixel.com/300/300);_x000D_
}_x000D_
.image:before {_x000D_
  content: "";_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_

Or you can use:

ssh -oStrictHostKeyChecking=no host

This will be insecure (man in the middle attacks) but easiest solution.

The better way to do that is to generate correct mappings between host and ip address, so ssh will not complain:

#!/bin/bash

for domain in "github.com" "bitbucket.org"; do
    sed -i "/$domain/d" ~/.ssh/known_hosts
    line=$(ssh-keyscan $domain,`nslookup $domain | awk '/^Address: / { print $2 ; exit }'`)
    echo $line >> ~/.ssh/known_hosts
done

Excerpt from gist.

<context:component-scan base-package="" /> 

tells Spring to scan those packages for Annotations.

<mvc:annotation-driven> 

registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.

This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.

You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.

The environment variables of a process exist at runtime, and are not stored in some file or so. They are stored in the process's own memory (that's where they are found to pass on to children). But there is a virtual file in

/proc/pid/environ

This file shows all the environment variables that were passed when calling the process (unless the process overwrote that part of its memory — most programs don't). The kernel makes them visible through that virtual file. One can list them. For example to view the variables of process 3940, one can do

cat /proc/3940/environ | tr '\0' '\n'

Each variable is delimited by a binary zero from the next one. tr replaces the zero into a newline.

Yes, you can set the screen orientation programatically anytime you want using:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

for landscape and portrait mode respectively. The setRequestedOrientation() method is available for the Activity class, so it can be used inside your Activity.

And this is how you can get the current screen orientation and set it adequatly depending on its current state:

Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
final int orientation = display.getOrientation(); 
 // OR: orientation = getRequestedOrientation(); // inside an Activity

// set the screen orientation on button click
Button btn = (Button) findViewById(R.id.yourbutton);
btn.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {

              switch(orientation) {
                   case Configuration.ORIENTATION_PORTRAIT:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                       break;
                   case Configuration.ORIENTATION_LANDSCAPE:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                       break;                   
               }
          }
   });

EDIT

Also, you can get the screen orientation using the Configuration:

Activity.getResources().getConfiguration().orientation

JPA is the interface, Hibernate is one implementation of that interface.

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

Disclaimer: Rust and Inkscape were chosen because of their size and safety to stay, no advertisement

If someone finds this question like me, here are my performance tests of proposed methods:

Python 2.7.8

In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop

In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop

In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop

As you can see, insert and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert is more common option and I, personally prefer this way to prepend to list.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.

Finally i have found a solution with javascript here is the link bellow :-

scrollable horizontal and vertical grid view with fixed headers

You want sys.exit(). From Python's docs:

>>> import sys
>>> print sys.exit.__doc__
exit([status])

Exit the interpreter by raising SystemExit(status).
If the status is omitted or None, it defaults to zero (i.e., success).
If the status is numeric, it will be used as the system exit status.
If it is another kind of object, it will be printed and the system
exit status will be one (i.e., failure).

So, basically, you'll do something like this:

from sys import exit

# Code!

exit(0) # Successful exit

LINQ is slower now, but it might get faster at some point. The good thing about LINQ is that you don't have to care about how it works. If a new method is thought up that's incredibly fast, the people at Microsoft can implement it without even telling you and your code would be a lot faster.

More importantly though, LINQ is just much easier to read. That should be enough reason.

It was resolved after upgrading pip:

python -m pip install --upgrade pip
pip install "package-name"

With yield you can easily describe the breakpoints between multiple tasks in a single function. That's all, there is nothing special about it.

$closure = function ($injected1, $injected2, ...){
    $returned = array();
    //task1 on $injected1
    $returned[] = $returned1;
//I need a breakpoint here!!!!!!!!!!!!!!!!!!!!!!!!!
    //task2 on $injected2
    $returned[] = $returned2;
    //...
    return $returned;
};
$returned = $closure($injected1, $injected2, ...);

If task1 and task2 are highly related, but you need a breakpoint between them to do something else:

• free memory between processing database rows
• run other tasks which provide dependency to the next task, but which are unrelated by understanding the current code
• doing async calls and wait for the results
• and so on ...

then generators are the best solution, because you don't have to split up your code into many closures or mix it with other code, or use callbacks, etc... You just use yield to add a breakpoint, and you can continue from that breakpoint if you are ready.

Add breakpoint without generators:

$closure1 = function ($injected1){
    //task1 on $injected1
    return $returned1;
};
$closure2 = function ($injected2){
    //task2 on $injected2
    return $returned1;
};
//...
$returned1 = $closure1($injected1);
//breakpoint between task1 and task2
$returned2 = $closure2($injected2);
//...

Add breakpoint with generators

$closure = function (){
    $injected1 = yield;
    //task1 on $injected1
    $injected2 = (yield($returned1));
    //task2 on $injected2
    $injected3 = (yield($returned2));
    //...
    yield($returnedN);
};
$generator = $closure();
$returned1 = $generator->send($injected1);
//breakpoint between task1 and task2
$returned2 = $generator->send($injected2);
//...
$returnedN = $generator->send($injectedN);

note: It is easy to make mistake with generators, so always write unit tests before you implement them! note2: Using generators in an infinite loop is like writing a closure which has infinite length...

I have also seen:

if(length(obj)) {
  # do this if object has length
  # NULL has no length
}

I don't think it's great though. Because some vectors can be of length 0. character(0), logical(0), integer(0) and that might be treated as a NULL instead of an error.

Add maven { url "https://maven.google.com" } to your root level build.gradle file

repositories {
    maven { url "https://maven.google.com" }
    flatDir {
        dirs 'libs'
    }
}

Adding to the top answer:

after the 2nd method did not initially seem to work I did some additional tinkering and have found the solution.

TLDR; the top answer's 2nd solution almost works, but for some versions of xCode ctrl+dragging to "Top Layout Guide" and selecting Vertical Spacing does nothing. However, by first adjusting the size of the Table View and then selecting "Top Space to Top Layout Guide" works

1. Drag a blank ViewController onto the storyboard.

2. Drag a UITableView object into the View. (Not UITableViewController). Position it in the very center using the blue layout guides.

3. Drag a UITableViewCell into the TableView. This will be your prototype reuse cell, so don't forget to set it's Reuse Identifier under the Attributes tab or you'll get a crash.

4. Create your custom subclass of UIViewController, and add the <UITableViewDataSource, UITableViewDelegate> protocols. Don't forget to set your storyboard's ViewController to this class in the Identity Inspector.

5. Create an outlet for your TableView in your implementation file, and name it "tableView"

6. Right click the TableView and drag both the dataSource and the delegate to your ViewController.

Now for the part of not clipping into the status bar.

7. Grab the top edge of your Table View and move it down to one of the dashed blue auto-layout guides that are near the top

8. Now, you can control drag from the Table View to the top and select Top Space to Top Layout Guide

9. It will give you an error about ambiguous layout of TableView, just Add Missing Constraints and your done.

Now you can set up your table view like normal, and it won't clip the status bar!

In IPython, I first use

In [2]: %hist

to view my past code. I select the chunk I want to save and then paste it into file my_file.py using the %%file magic (short for %%writefile)

In [3]: %%file my_file.py
   ...: # paste code here 
   ...:  
   ...:  

hitting return two times in the end.

To append to file use the option -a: %%file -a my_file.py.

If needed, I can list, edit, etc. the file in the underlying command line using the exclamation mark

In [5]: !ls -l my_file.py
In [6]: !vi my_file.py

var index,
    input = [1,2,3],
    indexToRemove = 1;
    integers = [];

for (index in input) {
    if (input.hasOwnProperty(index)) {
        if (index !== indexToRemove) {
            integers.push(result); 
        }
    }
}
input = integers;

This solution will take an array of input and will search through the input for the value to remove. This will loop through the entire input array and the result will be a second array integers that has had the specific index removed. The integers array is then copied back into the input array.

As now $this->getRequest() method is deprecated you need to inject Request object into your controller action like this:

public function someAction(Request $request)

after that you can use one of the following.

If you want to fetch POST data from request use following:

$request->request->get('var_name');

but if you want to fetch GET data from request use this:

$request->query->get('var_name');

One trick for this, for webkit browsers, is to create an invisible scrollbar, and then make it appear on hover. This method does not affect the scrolling area width as the space needed for the scrollbar is already there.

Something like this:

body {_x000D_
  height: 500px;_x000D_
  &::-webkit-scrollbar {_x000D_
    background-color: transparent;_x000D_
    width: 10px;_x000D_
  }_x000D_
  &::-webkit-scrollbar-thumb {_x000D_
    background-color: transparent;_x000D_
  }_x000D_
}_x000D_
_x000D_
body:hover {_x000D_
  &::-webkit-scrollbar-thumb {_x000D_
    background-color: black;_x000D_
  }_x000D_
}_x000D_
_x000D_
.full-width {_x000D_
  width: 100%;_x000D_
  background: blue;_x000D_
  padding: 30px;_x000D_
  color: white;_x000D_
}

some content here_x000D_
_x000D_
<div class="full-width">does not change</div>

If your project is Maven-based you can run all test-methods from test-class CustomTest which belongs to module 'my-module' using next command:

mvn clean test -pl :my-module -Dtest=CustomTest

Or run only 1 test-method myMethod from test-class CustomTest using next command:

mvn clean test -pl :my-module -Dtest=CustomTest#myMethod

For this ability you need Maven Surefire Plugin v.2.7.3+ and Junit 4. More details is here: http://maven.apache.org/surefire/maven-surefire-plugin/examples/single-test.html

EUROPE (ENGLISH/SPANISH) FORMAT
I you need to get the current day too, you can use this one.

function getFormattedDate(today) 
{
    var week = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');
    var day  = week[today.getDay()];
    var dd   = today.getDate();
    var mm   = today.getMonth()+1; //January is 0!
    var yyyy = today.getFullYear();
    var hour = today.getHours();
    var minu = today.getMinutes();

    if(dd<10)  { dd='0'+dd } 
    if(mm<10)  { mm='0'+mm } 
    if(minu<10){ minu='0'+minu } 

    return day+' - '+dd+'/'+mm+'/'+yyyy+' '+hour+':'+minu;
}

var date = new Date();
var text = getFormattedDate(date);

*For Spanish format, just translate the WEEK variable.

var week = new Array('Domingo', 'Lunes', 'Martes', 'Miércoles', 'Jueves', 'Viernes', 'Sábado');

Output: Monday - 16/11/2015 14:24

There is a comment on the top answer by @RyanMann that suggests:

Store your connection strings in one config file, then reference them in other projects by <connectionString configSource="../ProjectDir/SharedConnections.config" />

This is a fantastic suggestion!

It also works to share connection strings between App.config and Web.config files!

Anyone wanting to follow this suggestion, should head on over to this SO answer. It has a really great step-by-step guide on sharing connection strings among multiple projects in a solution.

The only caveat is that configSource must exist in the same directory or a sub-directory. The link above explains how to use "Add as Link" to get around this.

I usually fix this errore following this msdn blog post Using LocalDB with Full IIS

This requires editing applicationHost.config file which is usually located in C:\Windows\System32\inetsrv\config. Following the instructions from KB 2547655 we should enable both flags for Application Pool ASP.NET v4.0, like this:

<add name="ASP.NET v4.0" autoStart="true" managedRuntimeVersion="v4.0"     managedPipelineMode="Integrated">
    <processModel identityType="ApplicationPoolIdentity" loadUserProfile="true" setProfileEnvironment="true" />
</add>

You can do this in 2 ways. First is just to import the specific function you want from file.py. To do this use

from file import function

Another way is to import the entire file

import file as fl

Then you can call any function inside file.py using

fl.function(a,b)

Here goes:

DECLARE @var nvarchar(max) = 'Man''s best friend';

You will note that the ' is escaped by doubling it to ''.

Since the string delimiter is ' and not ", there is no need to escape ":

DECLARE @var nvarchar(max) = '"My Name is Luca" is a great song';

The second example in the MSDN page on DECLARE shows the correct syntax.

use box-shadow with no horizontal offset.

http://www.css3.info/preview/box-shadow/

eg.

div {_x000D_
  -webkit-box-shadow: 0 10px 5px #888888;_x000D_
  -moz-box-shadow: 0 10px 5px #888888;_x000D_
  box-shadow: 0 10px 5px #888888;_x000D_
}

<div>wefwefwef</div>

There will be a slight shadow on the sides with a large blur radius (5px in above example)

for i in count: means for i in 7:, which won't work. The bit after the in should be of an iterable type, not a number. Try this:

for i in range(count):

I have almost the same problems like this, the problems is come inside the pipeline when running my selenium test that need chromedriver package to running the e2e test.

My error build pipeline

The problems is just because in the pipeline (in my case) is having the chrome version 73, and my chromedriver package is installed on version 74.

Finally there are two simple solutions:

1. Downgrade your chrome

2. Downgrade your chromedriver package version. in my case, cause i running inside the pipeline i need to install chromedriver before running the selenium test like displayed below.

   - script: npm install [email protected] --chromedriver-force-download displayName: 'Install Chrome'

I like the error as return-value way. If you're designing the api and you want to make use of your library as painless as possible think about these additions:

• store all possible error-states in one typedef'ed enum and use it in your lib. Don't just return ints or even worse, mix ints or different enumerations with return-codes.

• provide a function that converts errors into something human readable. Can be simple. Just error-enum in, const char* out.

• I know this idea makes multithreaded use a bit difficult, but it would be nice if application programmer can set an global error-callback. That way they will be able to put a breakpoint into the callback during bug-hunt sessions.

Hope it helps.

While a good answer has been given (using Process.Start), it is safer to encapsulate it in a function that checks that the passed string is indeed a URI, to avoid accidentally starting random processes on the machine.

public static bool IsValidUri(string uri)
{
    if (!Uri.IsWellFormedUriString(uri, UriKind.Absolute))
        return false;
    Uri tmp;
    if (!Uri.TryCreate(uri, UriKind.Absolute, out tmp))
        return false;
    return tmp.Scheme == Uri.UriSchemeHttp || tmp.Scheme == Uri.UriSchemeHttps;
}

public static bool OpenUri(string uri) 
{
    if (!IsValidUri(uri))
        return false;
     System.Diagnostics.Process.Start(uri);
     return true;
}

You can use pigz instead of gzip, which does gzip compression on multiple cores. Instead of using the -z option, you would pipe it through pigz:

tar cf - paths-to-archive | pigz > archive.tar.gz

By default, pigz uses the number of available cores, or eight if it could not query that. You can ask for more with -p n, e.g. -p 32. pigz has the same options as gzip, so you can request better compression with -9. E.g.

tar cf - paths-to-archive | pigz -9 -p 32 > archive.tar.gz

$aa = fopen('a.txt','r');
echo fread($aa,filesize('a.txt'));

$a = fopen('a.txt','r');
while(!feof($a)){echo fgets($a)."<br>";}
fclose($a);

Possible solution to resolve your problem .

   public static string FirstToUpper(this string lowerWord)
   {
       if (string.IsNullOrWhiteSpace(lowerWord) || string.IsNullOrEmpty(lowerWord))
            return lowerWord;
       return new StringBuilder(lowerWord.Substring(0, 1).ToUpper())
                 .Append(lowerWord.Substring(1))
                 .ToString();
   }

It's best practice to hash passwords so they are not decryptable. This makes things slightly more difficult for attackers that may have gained access to your database or files.

If you must encrypt your data and have it decryptable, a guide to secure encryption/decryption is available at https://paragonie.com/white-paper/2015-secure-php-data-encryption. To summarize that link:

• Use Libsodium - A PHP extension
• If you can't use Libsodium, use defuse/php-encryption - Straight PHP code
• If you can't use Libsodium or defuse/php-encryption, use OpenSSL - A lot of servers will already have this installed. If not, it can be compiled with --with-openssl[=DIR]

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

check Robocopy:

ROBOCOPY \\server-source\c$\VMExports\ C:\VMExports\ /E /COPY:DAT

make sure you check what robocopy parameter you want. this is just an example. type robocopy /? in a comandline/powershell on your windows system.

You can use tojson to convert each record to JSON in a MongoDB shell script.

Run this script in RoboMongo:

var cursor = db.getCollection('foo').find({}, {});
while(cursor.hasNext()) {
    print(tojson(cursor.next()))
}

This prints all results as a JSON-like array.

The result is not really JSON! Some types, such as dates and object IDs, are printed as JavaScript function calls, e.g., ISODate("2016-03-03T12:15:49.996Z").

Might not be very efficient for large result sets, but you can limit the query. Alternatively, you can use mongoexport.

First make sure the required number is a valid index for the string from beginning or end , then you can simply use array subscript notation. use len(s) to get string length

>>> s = "python"
>>> s[3]
'h'
>>> s[6]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: string index out of range
>>> s[0]
'p'
>>> s[-1]
'n'
>>> s[-6]
'p'
>>> s[-7]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: string index out of range

In Identity inspector change class name with the corresponding identifier and also In Attributes inspector modify Indentifier then it should work as expected.

Take a look at this thread: http://code.google.com/p/chromium/issues/detail?id=4158

The problem is caused by javascript method "window.open(URL, windowName[, windowFeatures])". If the 3rd parameter windowFeatures is specified, then alert box doesn't work in the popup constrained window in Chrome, here is a simplified reduction:

http://go/reductions/4158/test-home-constrained.html

If the 3rd parameter windowFeatures is ignored, then alert box works in the popup in Chrome(the popup is actually opened as a new tab in Chrome), like this:

http://go/reductions/4158/test-home-newtab.html

it doesn't happen in IE7, Firefox3 or Safari3, it's a chrome specific issue.

Setting a buildpack on an application

You can change the buildpack used by an application by setting the buildpack value.
When the application is next pushed, the new buildpack will be used.

$ heroku buildpacks:set heroku/php

Buildpack set. Next release on random-app-1234 will use heroku/php.
Run git push heroku master to create a new release using this buildpack.

This is whay its not working for you since you did not set it up.

... When the application is next pushed, the new buildpack will be used.

You may also specify a buildpack during app creation:

$ heroku create myapp --buildpack heroku/python

When you are in the context of a trigger you have access to the logical table INSERTED which contains all the rows that have just been inserted to the table. You can build your insert to the other table based on a select from Inserted.

This is an direct excerpt from the excellent book 'Thinking in Java' by Bruce Eckel.

[..] Should you use an interface or an abstract class?

Well, an interface gives you the benefits of an abstract class and the benefits of an interface, so if it’s possible to create your base class without any method definitions or member variables you should always prefer interfaces to abstract classes.

In fact, if you know something is going to be a base class, your first choice should be to make it an interface, and only if you’re forced to have method definitions or member variables should you change to an abstract class.

In android-N, this feature is included in it. check Number-blocking update for android N

Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

advantage of are:

1. Numbers blocked on calls are also blocked on texts
2. Blocked numbers can persist across resets and devices through the Backup & Restore feature
3. Multiple apps can use the same blocked numbers list

For more information, see android.provider.BlockedNumberContract

Update an existing project.

To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).

Open the build.gradle file for your module and update the values as follows:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0 rc1
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

select regexp_replace(field, E'[\\n\\r\\u2028]+', ' ', 'g' )

I had the same problem in my postgres d/b, but the newline in question wasn't the traditional ascii CRLF, it was a unicode line separator, character U2028. The above code snippet will capture that unicode variation as well.

Update... although I've only ever encountered the aforementioned characters "in the wild", to follow lmichelbacher's advice to translate even more unicode newline-like characters, use this:

select regexp_replace(field, E'[\\n\\r\\f\\u000B\\u0085\\u2028\\u2029]+', ' ', 'g' )

If you do not want to use other library, here is a simple function to convert InputStream to OutputStream.

public static void copyStream(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while ((read = in.read(buffer)) != -1) {
        out.write(buffer, 0, read);
    }
}

Now you can easily write an Inputstream into file by using FileOutputStream-

FileOutputStream out = new FileOutputStream(outFile);
copyStream (inputStream, out);
out.close();

Ambu,

I was having the same issue as you, and this is the code I used to figure it out. Although, I don't use the footer row section for my purposes, I did include it in this code.

    DataTable dt = new DataTable();

    // add the columns to the datatable            
    if (GridView1.HeaderRow != null)
    {

        for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
        {
            dt.Columns.Add(GridView1.HeaderRow.Cells[i].Text);
        }
    }

    //  add each of the data rows to the table
    foreach (GridViewRow row in GridView1.Rows)
    {
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < row.Cells.Count; i++)
        {
            dr[i] = row.Cells[i].Text.Replace("&nbsp;","");
        }
        dt.Rows.Add(dr);
    }

    //  add the footer row to the table
    if (GridView1.FooterRow != null)
    {
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < GridView1.FooterRow.Cells.Count; i++)
        {
            dr[i] = GridView1.FooterRow.Cells[i].Text.Replace("&nbsp;","");
        }
        dt.Rows.Add(dr);
    }

While this is not a GUI tool, my quick tests indicated that diffxml has some promise. The author appears to have thought about the complexities of representing diffs for nested elements in a standardized way (his DUL - Delta Update Language specification).

Installing and running his tools, I can say that the raw text output is quite clear and concise. It doesn't offer the same degree of immediate apprehension as a GUI tool, but given that the output is standardized as DUL, perhaps you would be able to take that and build a tool to generate a visual representation. I'd certainly love to see one.

The author's "links" section does reference a few other XML differencing tools, but as you mentioned in your post, they're all proprietary.

Use newDirName = os.path.abspath(dir) to create a full directory path name for the subdirectory and then list its contents as you have done with the parent (i.e. newDirList = os.listDir(newDirName))

You can create a separate method of your code snippet and call it recursively through the subdirectory structure. The first parameter is the directory pathname. This will change for each subdirectory.

This answer is based on the 3.1.1 version documentation of the Python Library. There is a good model example of this in action on page 228 of the Python 3.1.1 Library Reference (Chapter 10 - File and Directory Access). Good Luck!

We can use,

$ rails d migration table_name  

Which will delete the migration.

add persist security info=True; in connection string.

You may simple get it with s3cmd command:

s3cmd get --recursive --continue s3://test-bucket local-directory/

You can use simple trick which is import flask app variable from main inside another file, like:

test-routes.py

from __main__ import app

@app.route('/test', methods=['GET'])
def test():
    return 'it works!'

and in your main files, where you declared flask app, import test-routes, like:

app.py

from flask import Flask, request, abort

app = Flask(__name__)

# import declared routes
import test-routes

It works from my side.

You could also do a set diff, for example:

list(set(nltk.regexp_tokenize(sentence, pattern, gaps=True)) - set(nltk.corpus.stopwords.words('english')))

Without any further information, which Database etc the best we can do is something like

Sql Server

SELECT TOP 1 * FROM Table ORDER BY ID DESC

MySql

SELECT * FROM Table ORDER BY ID DESC LIMIT 1

Assuming employee numbers are in the first column and their names are in the second:

=VLOOKUP(A1, Sheet2!A:B, 2,false)

For those unable to configure the mysql environment (e.g. due to lack of SUPER access) to use human-friendly timezone names like "America/Denver" or "GMT" you can also use the function with numeric offsets like this:

CONVERT_TZ(date,'+00:00','-07:00')

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).

Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?

Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -

// Error.h
class Error {
public:
  static Error& NOT_FOUND;
  static Error& UNKNOWN;
  static Error& NONE; // singleton object that represents null

public:
  static vector<shared_ptr<Error>> _instances;
  static Error& NewInstance(const string& name, bool isNull = false);

private:
  bool _isNull;
  Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
  Error() {};
  Error(const Error& src) {};
  Error& operator=(const Error& src) {};

public:
  operator Error*() { return _isNull ? nullptr : this; }
};

// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
  shared_ptr<Error> pNewInst(new Error(name, isNull)).
  Error::_instances.push_back(pNewInst);
  return *pNewInst.get();
}

Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");

// Main.cpp
#include "Error.h"

Error& getError() {
  return Error::UNKNOWN;
}

// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
  return Error::NONE;
}

int main(void) {
  if(getError() != Error::NONE) {
    return EXIT_FAILURE;
  }

  // Edit: To see the overload of "Error*()" in Error.h actually working
  if(getErrorNone() != nullptr) {
    return EXIT_FAILURE;
  }
}

Ajax is the way to go. The easiest (and probably the best) approach is jQuery ajax()

You'll end up writing something like this:

$.ajax({
  url: "test.html",
  context: document.body,
  success: function(){
    // do something when done
  }
});

See the following snippet, is this what you want?

body {
    background: silver;
    padding: 0 10px;
}

#content:after {
    height: 10px;
    display: block;
    width: 100px;
    background: #808080;
    border-right: 1px white;
    content: '';
}

#footer:before {
    display: block;
    content: '';
    background: silver;
    height: 10px;
    margin-top: -20px;
    margin-left: 101px;
}

#content {
    background: white;
}


#footer {
    padding-top: 10px;
    background: #404040;
}

p {
    padding: 100px;
    text-align: center;
}

#footer p {
    color: white;
}

<body>
    <div id="content"><p>#content</p></div>
    <div id="footer"><p>#footer</p></div>
</body>

JSFiddle

The auto_increment property only works for numeric columns (integer and floating point), not char columns:

CREATE TABLE discussion_topics (
    topic_id INT NOT NULL AUTO_INCREMENT,
    project_id char(36) NOT NULL,
    topic_subject VARCHAR(255) NOT NULL,
    topic_content TEXT default NULL,
    date_created DATETIME NOT NULL,
    date_last_post DATETIME NOT NULL,
    created_by_user_id char(36) NOT NULL,
    last_post_user_id char(36) NOT NULL,
    posts_count char(36) default NULL,
    PRIMARY KEY (topic_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

Use the sed delete command with a range address. For example:

sed 1,100d file.txt # Print file.txt omitting lines 1-100.

Alternatively, if you want to only print a known range, use the print command with the -n flag:

sed -n 201,300p file.txt # Print lines 201-300 from file.txt

This solution should work reliably on all Unix systems, regardless of the presence of GNU utilities.

Brad Wilson has a couple great articles on unobtrusive validation and unobtrusive ajax.
It is also shown very nicely in this Pluralsight video in the section on " AJAX and JavaScript".

Basically, it is simply Javascript validation that doesn't pollute your source code with its own validation code. This is done by making use of data- attributes in HTML.

I think this is the smartest and pithonic.

{'key1','key2'} <= my_dict.keys()

print("Hello, World!")

You are probably using Python 3.0, where print is now a function (hence the parenthesis) instead of a statement.

You could use a Common Table Expression to get the top 10 distinct ID's and then join those to the rest of your data:

;WITH TopTenIDs AS
( 
   SELECT DISTINCT TOP 10 id
   FROM dm.labs 
   ORDER BY ......
)
SELECT 
    tti.id, pl.nm, pl.val, pl.txt_val
FROM
    TopTenIDs tti
INNER JOIN
    dm.labs pl ON pl.id = tti.id
INNER JOIN 
    mas_data.patients p ON pl.id = p.id
WHERE
    pl.nm like '%LDL%'
    AND val IS NOT NULL

That should work. Mind you: if you have a "TOP x" clause, you typically also need an ORDER BY clause - if you want the TOP 10, you need to tell the system in what order that "TOP" is.

PS: why do you even join the "patients" table, if you never select any fields from it??

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

You can use this function in the route like this

app.get('/one/two', function (req, res) {
    const url = getFullUrl(req);
}

/**
 * Gets the self full URL from the request
 * 
 * @param {object} req Request
 * @returns {string} URL
 */
const getFullUrl = (req) => `${req.protocol}://${req.headers.host}${req.originalUrl}`;

req.protocol will give you http or https, req.headers.host will give you the full host name like www.google.com, req.originalUrl will give the rest pathName(in your case /one/two)

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.

Hey i figured it out shortly after. For some reason I was just having a brain fart.

image.frame = CGRectMake(0 , 0, self.view.frame.width, self.view.frame.height * 0.2)

crontab does not work for me on CentOS x86 6.5. @reboot seems to be not working.

Finally I got this solution:

Edit: /etc/rc.local

sudo vi /etc/rc.local

Add this line to the end of the file. Change USER_NAME and PATH_TO_PROJECT to your own. NODE_ENV=production means the app runs in production mode. You can add more lines if you need to run more than one node.js app.

su - USER_NAME -c "NODE_ENV=production /usr/local/bin/forever start /PATH_TO_PROJECT/app.js"

Don't set NODE_ENV in a separate line, your app will still run in development mode, because forever does not get NODE_ENV.

# WRONG!
su - USER_NAME -c "export NODE_ENV=production"

Save and quit vi (press ESC : w q return). You can try rebooting your server. After your server reboots, your node.js app should run automatically, even if you don't log into any account remotely via ssh.

You'd better set NODE_ENV environment in your shell. NODE_ENV will be set automatically when your account USER_NAME logs in.

echo export NODE_ENV=production >> ~/.bash_profile

So you can run commands like forever stop/start /PATH_TO_PROJECT/app.js via ssh without setting NODE_ENV again.

I've created a pared-down demo project for you.

• Source: https://github.com/bigfont/webapi-cors
• Api Link: https://cors-webapi.azurewebsites.net/api/values

You can try the above API Link from your local Fiddler to see the headers. Here is an explanation.

Global.ascx

All this does is call the WebApiConfig. It's nothing but code organization.

public class WebApiApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        WebApiConfig.Register(GlobalConfiguration.Configuration);
    }
}

WebApiConfig.cs

The key method for your here is the EnableCrossSiteRequests method. This is all that you need to do. The EnableCorsAttribute is a globally scoped CORS attribute.

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        EnableCrossSiteRequests(config);
        AddRoutes(config);
    }

    private static void AddRoutes(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "Default",
            routeTemplate: "api/{controller}/"
        );
    }

    private static void EnableCrossSiteRequests(HttpConfiguration config)
    {
        var cors = new EnableCorsAttribute(
            origins: "*", 
            headers: "*", 
            methods: "*");
        config.EnableCors(cors);
    }
}

Values Controller

The Get method receives the EnableCors attribute that we applied globally. The Another method overrides the global EnableCors.

public class ValuesController : ApiController
{
    // GET api/values
    public IEnumerable<string> Get()
    {
        return new string[] { 
            "This is a CORS response.", 
            "It works from any origin." 
        };
    }

    // GET api/values/another
    [HttpGet]
    [EnableCors(origins:"http://www.bigfont.ca", headers:"*", methods: "*")]
    public IEnumerable<string> Another()
    {
        return new string[] { 
            "This is a CORS response. ", 
            "It works only from two origins: ",
            "1. www.bigfont.ca ",
            "2. the same origin." 
        };
    }
}

Web.config

You do not need to add anything special into web.config. In fact, this is what the demo's web.config looks like - it's empty.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
</configuration>

var url = "https://cors-webapi.azurewebsites.net/api/values"_x000D_
_x000D_
$.get(url, function(data) {_x000D_
  console.log("We expect this to succeed.");_x000D_
  console.log(data);_x000D_

In my case I just needed to remove Homebrew's executable using:

sudo rm -f `which brew`

Then reinstall Homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

It may not work for you if you use localhost/info.php.

You may be able to found the clue from the error. Find the port number in the error message. To me it was 80. I changed address as http://localhost:80/info.php, and then it worked to me.

To answer the question more generaly how to redirect standard output to a variable ?

do the following :

from io import StringIO
import sys

result = StringIO()
sys.stdout = result
result_string = result.getvalue()

If you need to do that only in some function do the following :

old_stdout = sys.stdout  

# your function containing the previous lines
my_function()

sys.stdout = old_stdout

You can try using the LayoutParams for this

public void zoom(boolean flag){
    if(flag){
        int width=40;
        int height=40;
    }
    else{
        int width=20;
        int height=20;
    }
    RelativeLayout.LayoutParams param=new RelativeLayout.LayoutParams(width,height); //use the parent layout of the ImageView;
    imageView.setLayoutParams(param); //imageView is the view which needs zooming.
}

ZoomIn = zoom(true); ZoomOut = zoom(false);

I am not very sure whether it will make any difference in performance of my API.

Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async" considerations in my article on async ASP.NET.

I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.

As far as the code goes, this is not asynchronous:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
  var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
  return Task.FromResult(response);
}

You'd need a truly asynchronous implementation to get the scalability benefits of async:

public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Or (if your logic in this method really is just a pass-through):

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
  return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}

Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync). Then let the async trickle up, making your controller actions asynchronous as the last step.

And under no circumstances should you use Task.Run in this scenario.

Get the router from the container.

$router = $this->get('router');

Then use the router to generate the Url

$uri = $router->generate('blog_show', array('slug' => 'my-blog-post'));

If you are not limited to using ftplib you can also give wget module a try. Here, is the snippet

import wget
file_loc = 'http://www.website.com/foo.zip'
wget.download(file_loc)

Given a quadratic equation: x² − 4.0000000 x + 3.9999999 = 0, the exact roots to 10 significant digits are, r₁ = 2.000316228 and r₂ = 1.999683772.

Using float and double, we can write a test program:

#include <stdio.h>
#include <math.h>

void dbl_solve(double a, double b, double c)
{
    double d = b*b - 4.0*a*c;
    double sd = sqrt(d);
    double r1 = (-b + sd) / (2.0*a);
    double r2 = (-b - sd) / (2.0*a);
    printf("%.5f\t%.5f\n", r1, r2);
}

void flt_solve(float a, float b, float c)
{
    float d = b*b - 4.0f*a*c;
    float sd = sqrtf(d);
    float r1 = (-b + sd) / (2.0f*a);
    float r2 = (-b - sd) / (2.0f*a);
    printf("%.5f\t%.5f\n", r1, r2);
}   

int main(void)
{
    float fa = 1.0f;
    float fb = -4.0000000f;
    float fc = 3.9999999f;
    double da = 1.0;
    double db = -4.0000000;
    double dc = 3.9999999;
    flt_solve(fa, fb, fc);
    dbl_solve(da, db, dc);
    return 0;
}  

Running the program gives me:

2.00000 2.00000
2.00032 1.99968

Note that the numbers aren't large, but still you get cancellation effects using float.

(In fact, the above is not the best way of solving quadratic equations using either single- or double-precision floating-point numbers, but the answer remains unchanged even if one uses a more stable method.)

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

This solution worked for me using PyQt5 version 5.15.0

import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtCore import QUrl
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    loader = QtWebEngineWidgets.QWebEngineView()
    loader.setZoomFactor(1)
    layout = QPageLayout()
    layout.setPageSize(QPageSize(QPageSize.A4Extra))
    layout.setOrientation(QPageLayout.Portrait)
    loader.load(QUrl('https://stackoverflow.com/questions/23359083/how-to-convert-webpage-into-pdf-by-using-python'))
    loader.page().pdfPrintingFinished.connect(lambda *args: QApplication.exit())

    def emit_pdf(finished):
        loader.page().printToPdf("test.pdf", pageLayout=layout)

    loader.loadFinished.connect(emit_pdf)
    sys.exit(app.exec_())

I came across this question as a duplicate of a newer question which asked what the non-deprecated way to get a Date at a specific year, month, and day was.

The answers here so far say to use the Calendar class, and that was true until Java 8 came out. But as of Java 8, the standard way to do this is:

LocalDate localDate = LocalDate.of(1985, 1, 1);

And then if you really really need a java.util.Date, you can use the suggestions in this question.

For more info, check out the API or the tutorials for Java 8.

Use this

@Cacheable(value="bookCache", key="#isbn + '_' + #checkWarehouse + '_' + #includeUsed")

The function name does not reflect the semantic of the function. In fact you do not append a character. You create a new character array that contains the original array plus the given character. So if you indeed need a function that appends a character to a character array I would write it the following way

bool AppendCharToCharArray( char *array, size_t n, char c )
{
    size_t sz = std::strlen( array );

    if ( sz + 1 < n ) 
    {
        array[sz] = c;
        array[sz + 1] = '\0';
    }       

    return ( sz + 1 < n );
} 

If you need a function that will contain a copy of the original array plus the given character then it could look the following way

char * CharArrayPlusChar( const char *array, char c )
{
    size_t sz = std::strlen( array );
    char *s = new char[sz + 2];

    std::strcpy( s, array );
    s[sz] = c;
    s[sz + 1] = '\0';

    return ( s );
} 

Try font-weight:normal;

h1 {
    font-weight: normal;
}

I changed the Specific Version Property of the Refrences to false and that helped.

You can connect with MSSMS to LocalDB. Type only in SERVER NAME: (localdb)\v11.0 and leave it by Windows Authentication and it connects to your LocalDB server and shows you the databases in it.

If you're unlucky enough to be switching back and forth from a network behind a proxy and a network NOT behind a proxy, you may have forgotten that your NPM config is set to expect a proxy.

For me, I had to open up ~/.npmrc and comment out my proxy settings (while at home) and vice versa while at work (behind the proxy).

You can also use this format:

moment().format('ddd, ll'); // Wed, Jan 4, 2017

For reference I was looking at the same problem, I wanted to join the string value of stream elements in the reverse order.

itemList = { last, middle, first } => first,middle,last

I started to use an intermediate collection with collectingAndThen from comonad or the ArrayDeque collector of Stuart Marks, although I wasn't happy with intermediate collection, and streaming again

itemList.stream()
        .map(TheObject::toString)
        .collect(Collectors.collectingAndThen(Collectors.toList(),
                                              strings -> {
                                                      Collections.reverse(strings);
                                                      return strings;
                                              }))
        .stream()
        .collect(Collector.joining());

So I iterated over Stuart Marks answer that was using the Collector.of factory, that has the interesting finisher lambda.

itemList.stream()
        .collect(Collector.of(StringBuilder::new,
                             (sb, o) -> sb.insert(0, o),
                             (r1, r2) -> { r1.insert(0, r2); return r1; },
                             StringBuilder::toString));

Since in this case the stream is not parallel, the combiner is not relevant that much, I'm using insert anyway for the sake of code consistency but it does not matter as it would depend of which stringbuilder is built first.

I looked at the StringJoiner, however it does not have an insert method.

In windows, you can use _getch() in the

<conio.h>

header.

Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:

void swapCase(char *name);

or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.

The following code allows you to benefit from all SSL validation checks (e.g. date validity, CA certificate chain ...) EXCEPT a pluggable verification step e.g. to verify the hostname or do other additional certificate verification steps.

from httplib import HTTPSConnection
import ssl


def create_custom_HTTPSConnection(host):

    def verify_cert(cert, host):
        # Write your code here
        # You can certainly base yourself on ssl.match_hostname
        # Raise ssl.CertificateError if verification fails
        print 'Host:', host
        print 'Peer cert:', cert

    class CustomHTTPSConnection(HTTPSConnection, object):
        def connect(self):
            super(CustomHTTPSConnection, self).connect()
            cert = self.sock.getpeercert()
            verify_cert(cert, host)

    context = ssl.create_default_context()
    context.check_hostname = False
    return CustomHTTPSConnection(host=host, context=context)


if __name__ == '__main__':
    # try expired.badssl.com or self-signed.badssl.com !
    conn = create_custom_HTTPSConnection('badssl.com')
    conn.request('GET', '/')
    conn.getresponse().read()

Tested on both spark-shell version 1.6.3 and spark2-shell version 2.3.0.2.6.5.179-4, you can directly pipe to the shell's stdin like

spark-shell <<< "1+1"

or in your use case,

spark-shell < file.spark

I have recently the same issue in emulator, Nexus 5 (Android O). I have go to Android Virtual Device Manager and Wipe User Data and it solved my Problem.

The best approach to embed a SWF into an HTML page is to use SWFObject.

It is a simple open-source JavaScript library that is easy-to-use and standards-friendly method to embed Flash content.

It also offers Flash player version detection. If the user does not have the version of Flash required or has JavaScript disabled, they will see an alternate content. You can also use this library to trigger a Flash player upgrade. Once the user has upgraded, they will be redirected back to the page.

An example from the documentation:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
  <head>
    <title>SWFObject dynamic embed - step 3</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <script type="text/javascript" src="swfobject.js"></script>

    <script type="text/javascript">
        swfobject.embedSWF("myContent.swf", "myContent", "300", "120", "9.0.0");
    </script>

  </head>
  <body>
    <div id="myContent">
      <p>Alternative content</p>
    </div>
  </body>
</html>

A good tool to use along with this is the SWFObject HTML and JavaScript generator. It basically generates the HTML and JavaScript you need to embed the Flash using SWFObject. Comes with a very simple UI for you to input your parameters.

It Is highly recommended and very simple to use.

I know this is an older thread, but just to add another perspective. I'd assert that using overrides is really a bit of a code smell and will quickly get out of hand on larger projects. Today you're overriding Buttons, tomorrow Modals, the next day it Dropdowns, etc., etc.

I'd advise to try possibly commenting out the include for buttons.less and either define my own, or, find another Buttons library that's more suitable to my project. Shameless plug: here's an example of how easy it is to mix our Buttons library with TB: Using Buttons with Twitter Bootstrap. In practice, again, you'd likely want to remove the buttons.less include altogether to improve performance but this shows how you can make things look a bit less "generic". I haven't done this exercise yet myself but I'd imagine you could start by simply commenting out lines like:

https://github.com/twbs/bootstrap/blob/master/less/bootstrap.less#L17

And then recompiling using `lessc using one of your own buttons modules. That way you get the battle tested core of TB but can still customize things without resorting to major overrides. There's absolutely no reason not to use only parts of a library like Bootstrap. Of course the same applies to the Sass version of TB

If you want to start with a file you can do this

[xml]$cn = Get-Content config.xml
$cn.xml.Section.BEName

You may want to look at Tibbo VSPDL for creating a linux virtual serial port using a Kernel driver -- it seems pretty new, and is available for download right now (beta version). Not sure about the license at this point, or whether they want to make it available commercially only in the future.

There are other commercial alternatives, such as http://www.ttyredirector.com/.

In Open Source, Remserial (GPL) may also do what you want, using Unix PTY's. It transmits the serial data in "raw form" to a network socket; STTY-like setup of terminal parameters must be done when creating the port, changing them later like described in RFC 2217 does not seem to be supported. You should be able to run two remserial instances to create a virtual nullmodem like com0com, except that you'll need to set up port speed etc in advance.

Socat (also GPL) is like an extended variant of Remserial with many many more options, including a "PTY" method for redirecting the PTY to something else, which can be another instance of Socat. For Unit tets, socat is likely nicer than remserial because you can directly cat files into the PTY. See the PTY example on the manpage. A patch exists under "contrib" to provide RFC2217 support for negotiating serial line settings.

Yes there is, since setState works in an asynchronous way. That means after calling setState the this.state variable is not immediately changed. so if you want to perform an action immediately after setting state on a state variable and then return a result, a callback will be useful

Consider the example below

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value });
  this.validateTitle();
},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

The above code may not work as expected since the title variable may not have mutated before validation is performed on it. Now you may wonder that we can perform the validation in the render() function itself but it would be better and a cleaner way if we can handle this in the changeTitle function itself since that would make your code more organised and understandable

In this case callback is useful

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value }, function() {
    this.validateTitle();
  });

},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

Another example will be when you want to dispatch and action when the state changed. you will want to do it in a callback and not the render() as it will be called everytime rerendering occurs and hence many such scenarios are possible where you will need callback.

Another case is a API Call

A case may arise when you need to make an API call based on a particular state change, if you do that in the render method, it will be called on every render onState change or because some Prop passed down to the Child Component changed.

In this case you would want to use a setState callback to pass the updated state value to the API call

....
changeTitle: function (event) {
  this.setState({ title: event.target.value }, () => this.APICallFunction());
},
APICallFunction: function () {
  // Call API with the updated value
}
....

If you want to remove all lines in a file from your current line number, use dG, it will delete all lines (shift g) mean end of file

(Google search brought me to this question even though I did not ask for perl)

I had a problem with running scripts (albeit bash not perl). Apache had a config of ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ however Apache error log showed File does not exist: /var/www/cgi-bin/test.html.

Tried putting the script in both /usr/lib/cgi-bin/ and /var/www/cgi-bin/ but neither were working.

After a prolonged googling session what cracked it for me was sudo a2enmod cgi and everything fell into place using /usr/lib/cgi-bin/.

You can use parents method with specified .class selector and check if any of them matches it:

if ($elem.parents('.left').length != 0) {
    //someone has this class
}

A better solution with ref to avoid findDOMNode that is discouraged.

...
onScroll() {
    let offsetTop  = this.instance.getBoundingClientRect().top;
}
...
render() {
...
<Component ref={(el) => this.instance = el } />
...

For dynamically scaling using XML there is an attribute called "android:layout_weight"

The below example, modified from synic's response on this thread, shows a button that takes up 75% of the screen (weight = .25) and a text view taking up the remaining 25% of the screen (weight = .75).

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight=".25"
        android:text="somebutton">

    <TextView android:layout_width="fill_parent"
        android:layout_height="Wrap_content"
        android:layout_weight=".75">
</LinearLayout>

Ant is already installed on some older versions of Mac OS X, so you should run ant -version to test if it is installed before attempting to install it.

If it is not already installed, then your best bet is to install Homebrew (brew install ant) or MacPorts (sudo port install apache-ant), and use those tools to install Apache Ant.

Alternatively, though I would highly advise using Homebrew or MacPorts instead, you can install Apache Ant manually. To do so, you would need to:

1. Decompress the .tar.gz file.
2. Optionally put it somewhere.
3. Put the "bin" subdirectory in your path.

The commands that you would need, assuming apache-ant-1.8.1-bin.tar.gz (replace 1.8.1 with the actual version) were still in your Downloads directory, would be the following (explanatory comments included):

cd ~/Downloads # Let's get into your downloads folder.
tar -xvzf apache-ant-1.8.1-bin.tar.gz # Extract the folder
sudo mkdir -p /usr/local # Ensure that /usr/local exists
sudo cp -rf apache-ant-1.8.1-bin /usr/local/apache-ant # Copy it into /usr/local
# Add the new version of Ant to current terminal session
export PATH=/usr/local/apache-ant/bin:"$PATH"
# Add the new version of Ant to future terminal sessions
echo 'export PATH=/usr/local/apache-ant/bin:"$PATH"' >> ~/.profile
# Verify new version of ant
ant -version

Time of Sleep Function is in milliseconds (ms)

if you want 3 minutes, thats the way to do it:

WScript.Sleep(1000 * 60 * 3)

The following should work fine:

git diff -z --name-only commit1 commit2 | xargs -0 -IREPLACE rsync -aR REPLACE /home/changes/protected/

To explain further:

• The -z to with git diff --name-only means to output the list of files separated with NUL bytes instead of newlines, just in case your filenames have unusual characters in them.

• The -0 to xargs says to interpret standard input as a NUL-separated list of parameters.

• The -IREPLACE is needed since by default xargs would append the parameters to the end of the rsync command. Instead, that says to put them where the later REPLACE is. (That's a nice tip from this Server Fault answer.)

• The -a parameter to rsync means to preserve permissions, ownership, etc. if possible. The -R means to use the full relative path when creating the files in the destination.

Update: if you have an old version of xargs, you'll need to use the -i option instead of -I. (The former is deprecated in later versions of findutils.)

That 'u' is part of the external representation of the string, meaning it's a Unicode string as opposed to a byte string. It's not in the string, it's part of the type.

As an example, you can create a new Unicode string literal by using the same synax. For instance:

>>> sandwich = u"smörgås"
>>> sandwich
u'sm\xf6rg\xe5s'

This creates a new Unicode string whose value is the Swedish word for sandwich. You can see that the non-English characters are represented by their Unicode code points, ö is \xf6 and å is \xe5. The 'u' prefix appears just like in your example to signify that this string holds Unicode text.

To get rid of those, you need to encode the Unicode string into some byte-oriented representation, such as UTF-8. You can do that with e.g.:

>>> sandwich.encode("utf-8")
'sm\xc3\xb6rg\xc3\xa5s'

Here, we get a new string without the prefix 'u', since this is a byte string. It contains the bytes representing the characters of the Unicode string, with the Swedish characters resulting in multiple bytes due to the wonders of the UTF-8 encoding.

What you probably want is for...of, a relatively new construct built for the express purpose of enumerating the values of iterable objects:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

... as distinct from for...in, which enumerates property names (presumably¹ numeric indices in the case of arrays). Your loop displayed unexpected results because you didn't use the property names to get the corresponding values via bracket notation... but you could have:

let myArray = ["a","b","c","d"];_x000D_
for (let key in myArray) {_x000D_
  let value =  myArray[key]; // get the value by key_x000D_
  console.log("key: %o, value: %o", key, value);_x000D_
}

_{¹ Unfortunately, someone may have added enumerable properties to the array or its prototype chain which are not numeric indices... or they may have assigned an index leaving unassigned indices in the interim range. The issues are explained pretty well here. The main takeaway is that it's best to loop explicitly from 0 to array.length - 1 rather than using for...in.}

So, this is not (as I'd originally thought) an academic question, i.e.:

Without regard for practicality, is it possible to avoid length when iterating over an array?

According to your comment (emphasis mine):

[...] why do I need to calculate the size of an array whereas the interpreter can know it.

You have a misguided aversion to Array.length. It's not calculated on the fly; it's updated whenever the length of the array changes. You're not going to see performance gains by avoiding it (apart from caching the array length rather than accessing the property):

Now, even if you did get some marginal performance increase, I doubt it would be enough to justify the risk of dealing with the aforementioned issues.

function changeStyle(findSelector, newRules) {
    // Change original css style declaration.   
    for ( s in document.styleSheets ) {
        var CssRulesStyle = document.styleSheets[s].cssRules;
        for ( x in CssRulesStyle ) {
            if ( CssRulesStyle[x].selectorText == findSelector) {
                for ( cssprop in newRules ) {
                    CssRulesStyle[x].style[cssprop] = newRules[cssprop];
                }

                return true;
            }
        }
    }

    return false;
}

changeStyle('#exact .myStyle .declaration', {'width':'200px', 'height':'400px', 'color':'#F00'});

Another one solution can be used for class components - just override default MUI Theme properties with MuiThemeProvider. This will give more flexibility in comparison with other methods - you can use more than one MuiThemeProvider inside your parent component.

simple steps:

1. import MuiThemeProvider to your class component
2. import createMuiTheme to your class component
3. create new theme
4. wrap target MUI component you want to style with MuiThemeProvider and your custom theme

please, check this doc for more details: https://material-ui.com/customization/theming/

import React from 'react';
import PropTypes from 'prop-types';
import Button from '@material-ui/core/Button';

import { MuiThemeProvider } from '@material-ui/core/styles';
import { createMuiTheme } from '@material-ui/core/styles';

const InputTheme = createMuiTheme({
    overrides: {
        root: {
            background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
            border: 0,
            borderRadius: 3,
            boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
            color: 'white',
            height: 48,
            padding: '0 30px',
        },
    }
});

class HigherOrderComponent extends React.Component {

    render(){
        const { classes } = this.props;
        return (
            <MuiThemeProvider theme={InputTheme}>
                <Button className={classes.root}>Higher-order component</Button>
            </MuiThemeProvider>
        );
    }
}

HigherOrderComponent.propTypes = {
    classes: PropTypes.object.isRequired,
};

export default HigherOrderComponent;

Many of the mentioned examples (e.g. git diff 15dc8^!, or git diff 15dc8^..15dc8) don't work if you are using zsh and have extendedglob option set. You can fix it by one of the following three ways:

1. unsetopt extendedglob (and/or remove it from .zshrc)

2. setopt NO_NOMATCH (and/or set it in .zshrc)

3. escape the caret and bang every time with a backslash, e.g. git diff 15dc8\^\!

From the book Working Effectively with Legacy Code:

"If we need to test a private method, we should make it public. If making it public bothers us, in most cases, it means that our class is doing too much and we ought to fix it."

The way to fix it, according to the author, is by creating a new class and adding the method as public.

The author explains further:

"Good design is testable, and design that isn't testable is bad."

So, within these limits, your only real option is to make the method public, either in the current or a new class.

The problem with all of these answers for me was they weren't responsive. I had to have a fixed height for a parent div which i didn't want. I also didn't want to spend a ton of time dinking around with media queries. If you are using angular, you can use bootstraps tabset and it will do all of the hard work for you. You'll be able to scroll the inner content and it will be responsive. When you setup the tab, do it like this: $scope.tab = { title: '', url: '', theclass: '', ative: true }; ... the point is, you don't want a title or image icon. then hide the outline of the tab in cs like this:

.nav-tabs {
   border-bottom:none; 
} 

and also this .nav-tabs > li.active > a, .nav-tabs > li.active > a:hover, .nav-tabs > li.active > a:focus {border:none;} and finally to remove the invisible tab that you can still click on if you don't implement this: .nav > li > a {padding:0px;margin:0px;}

There is also argparse stdlib module (an "impovement" on stdlib's optparse module). Example from the introduction to argparse:

# script.py
import argparse

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument(
        'integers', metavar='int', type=int, choices=range(10),
         nargs='+', help='an integer in the range 0..9')
    parser.add_argument(
        '--sum', dest='accumulate', action='store_const', const=sum,
        default=max, help='sum the integers (default: find the max)')

    args = parser.parse_args()
    print(args.accumulate(args.integers))

Usage:

$ script.py 1 2 3 4
4

$ script.py --sum 1 2 3 4
10

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

Yeah, this appears to be a common standard. Some coders use self, others use me. It's used as a reference back to the "real" object as opposed to the event.

It's something that took me a little while to really get, it does look odd at first.

I usually do this right at the top of my object (excuse my demo code - it's more conceptual than anything else and isn't a lesson on excellent coding technique):

function MyObject(){
  var me = this;

  //Events
  Click = onClick; //Allows user to override onClick event with their own

  //Event Handlers
  onClick = function(args){
    me.MyProperty = args; //Reference me, referencing this refers to onClick
    ...
    //Do other stuff
  }
}

See this post where I have submitted Utils.java example to provide pure-java implementations and works without WifiManager. Some android devices may not have wifi available or are using ethernet wiring.

Utils.getMACAddress("wlan0");
Utils.getMACAddress("eth0");
Utils.getIPAddress(true); // IPv4
Utils.getIPAddress(false); // IPv6 

I would answer this with multiple options actually, the some of which actually render in the body.

• Place library script such as the jQuery library in the head section.
• Place normal script in the head unless it becomes a performance/page load issue.
• Place script associated with includes, within and at the end of that include. One example of this is .ascx user controls in asp.net pages - place the script at the end of that markup.
• Place script that impacts the render of the page at the end of the body (before the body closure).
• do NOT place script in the markup such as <input onclick="myfunction()"/> - better to put it in event handlers in your script body instead.
• If you cannot decide, put it in the head until you have a reason not to such as page blocking issues.

Footnote: "When you need it and not prior" applies to the last item when page blocking (perceptual loading speed). The user's perception is their reality—if it is perceived to load faster, it does load faster (even though stuff might still be occurring in code).

Side note: IF you place script blocks within markup, it may effect layout in certain browsers by taking up space (ie7 and opera 9.2 are known to have this issue) so place them in a hidden div (use a css class like: .hide { display: none; visibility: hidden; } on the div)

Standards: Note that the standards allow placement of the script blocks virtually anywhere if that is in question: http://www.w3.org/TR/1999/REC-html401-19991224/sgml/dtd.html and http://www.w3.org/TR/xhtml11/xhtml11_dtd.html

EDIT2: Note that whenever possible (always?) you should put the actual Javascript in external files and reference those - this does not change the pertinent sequence validity.

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

I know this is old but I found the way to make unload work using Chrome

window.onbeforeunload = function () {
  myFunction();
};

Put something like:

#!/usr/bin/env/python
import sys
if sys.version_info<(2,6,0):
  sys.stderr.write("You need python 2.6 or later to run this script\n")
  exit(1)

at the top of your script.

Note that depending on what else is in your script, older versions of python than the target may not be able to even load the script, so won't get far enough to report this error. As a workaround, you can run the above in a script that imports the script with the more modern code.

Set the html and body tags height to 100% and remove the margin around the body:

html, body {
    height: 100%;
    margin: 0px; /* Remove the margin around the body */
}

Now set the position of your div to fixed:

#dimScreen
{
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);

    position: fixed;
    top: 0px;
    left: 0px;

    z-index: 1000; /* Now the div will be on top */

It's much simpler to do this:

DateTime dt = new DateTime(633896886277130000);

Which gives

dt.ToString() ==> "9/27/2009 10:50:27 PM"

You can format this any way you want by using dt.ToString(MyFormat). Refer to this reference for format strings. "MMMM dd, yyyy" works for what you specified in the question.

Not sure where you get October 1.

Doing a symlink solves the issue:

ln -s /usr/bin/nodejs /usr/bin/node

(My thanks and +1 vote to bodokaiser's answer).

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

Fix for Android N & above: I had similar issue and mange to solve it by following steps described in https://developer.android.com/training/articles/security-config

But the config changes, without any complicated code logic, would only work on Android version 24 & above.

Fix for all version, including version < N: So for android lower then N (version 24) the solution is to via code changes as mentioned above. If you are using OkHttp, then follow the customTrust: https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/CustomTrust.java

$(document).ready(function () {
    $(document).on('change', 'input[Id="chkproperty"]', function (e) {
        alert($(this).val());
    });
});

Command-line SVN

You need to add your files to your working copy, before you commit your changes to the repository:

svn add <file|folder>

Afterwards:

svn commit

See here for detailed information about svn add.

TortoiseSVN

It works with TortoiseSVN, because it adds the file to your working copy automatically (commit dialog):

If you want to include an unversioned file, just check that file to add it to the commit.

See: TortoiseSVN: Committing Your Changes To The Repository

There is no button type cancel https://www.w3schools.com/jsref/prop_pushbutton_type.asp

To achieve cancel functionality I used DOM history

<button type="button" class="btn btn-primary" onclick="window.history.back();">Cancel</button>

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Rows.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Cells.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Count
