The problem that I had with the above is that I wanted to associate a short cut key with a macro in an xlam which has no visible interface. I found that the folllowing worked

To associate a short cut key with a macro

In Excel (not VBA) on the Developer Tab click Macros - no macros will be shown Type the name of the Sub The Options button should then be enabled Click it Ctrl will be the default Hold down Shift and press the letter you want eg Shift and A will associate Ctrl-Shift-A with the Sub

A simple way of using one instance of logging library in multiple modules for me was following solution:

base_logger.py

import logging

logger = logging
logger.basicConfig(format='%(asctime)s - %(message)s', level=logging.INFO)

Other files

from base_logger import logger

if __name__ == '__main__':
    logger.info("This is an info message")

Building on the previous answer, this bash one-liner should give you what you're looking for. It displays the git blame history for a particular line of a particular file, through the last 5 revisions:

LINE=10 FILE=src/options.cpp REVS=5; for commit in $(git rev-list -n $REVS HEAD $FILE); do git blame -n -L$LINE,+1 $commit -- $FILE; done

In the output of this command, you might see the content of the line change, or the line number displayed might even change, for a particular commit.

This often indicates that the line was added for the first time, after that particular commit. It could also indicate the line was moved from another part of the file.

I assigned the javascript in my Controller:

model.linkCode = "window.open('https://www.yahoo.com', '_blank')";

And in my view:

@section Scripts{
    <script @Html.CspScriptNonce()>

    $(function () {

        @if (!String.IsNullOrEmpty(Model.linkCode))
        {
            WriteLiteral(Model.linkCode);
        }
    });

That opened a new tab with the link, and went to it.

Interestingly, run locally it engaged a popup blocker, but seemed to work fine on the servers.

You can also use Scanner :

Scanner s = new Scanner(MyString);
s.nextInt();

You can add multiple li in ol tag that has attribute as class with value "carousel-indicators" and with data-slide-to has sequential values like 0 to 6 or 0 to 9.

than you just need to copy and paste the div which has attribute as class with value "item".

This works for me.

<div data-ride="carousel" class="carousel slide" id="myCarousel">
    <!-- Indicators -->
    <ol class="carousel-indicators">
        <li class="" data-slide-to="0" data-target="#myCarousel"></li>
        <li data-slide-to="1" data-target="#myCarousel" class=""></li>
        <li data-slide-to="2" data-target="#myCarousel" class="active"></li>
        <li data-slide-to="3" data-target="#myCarousel" class=""></li>
        <li data-slide-to="4" data-target="#myCarousel" class=""></li>
        <li data-slide-to="5" data-target="#myCarousel" class=""></li>
        <li data-slide-to="6" data-target="#myCarousel" class=""></li>
    </ol>
    <div role="listbox" class="carousel-inner">
        <div class="item active">
            <img alt="First slide" src="images/carousel/11.jpg"
                class="first-slide">
        </div>
        <div class="item">
            <img alt="Second slide" src="images/carousel/22.jpg"
                class="second-slide">
        </div>
        <div class="item">
            <img alt="Third slide" src="images/carousel/33.jpg"
                class="third-slide">
        </div>
        <div class="item">
            <img alt="Third slide" src="images/carousel/44.jpeg"
                class="fourth-slide">
        </div>
        <div class="item">
            <img alt="Third slide" src="images/carousel/55.jpg"
                class="third-slide">
        </div>
        <div class="item">
            <img alt="Third slide" src="images/carousel/66.jpg"
                class="third-slide">
        </div>
        <div class="item">
            <img alt="Third slide" src="images/carousel/77.jpg"
                class="third-slide">
        </div>
    </div>
    <a data-slide="prev" role="button" href="#myCarousel"
        class="left carousel-control"> <span aria-hidden="true"
        class="glyphicon glyphicon-chevron-left"></span> <span
        class="sr-only">Previous</span>
    </a> <a data-slide="next" role="button" href="#myCarousel"
        class="right carousel-control"> <span aria-hidden="true"
        class="glyphicon glyphicon-chevron-right"></span> <span
        class="sr-only">Next</span>
    </a>
</div>

There are two methods you can use. Both require creating a user and a database.

By default psql connects to the database with the same name as the user. So there is a convention to make that the "user's database". And there is no reason to break that convention if your user only needs one database. We'll be using mydatabase as the example database name.

1. Using createuser and createdb, we can be explicit about the database name,

   $ sudo -u postgres createuser -s $USER
   $ createdb mydatabase
   $ psql -d mydatabase
   

   You should probably be omitting that entirely and letting all the commands default to the user's name instead.

   $ sudo -u postgres createuser -s $USER
   $ createdb
   $ psql
   

2. Using the SQL administration commands, and connecting with a password over TCP

   $ sudo -u postgres psql postgres
   

   And, then in the psql shell

   CREATE ROLE myuser LOGIN PASSWORD 'mypass';
   CREATE DATABASE mydatabase WITH OWNER = myuser;
   

   Then you can login,

   $ psql -h localhost -d mydatabase -U myuser -p <port>
   

   If you don't know the port, you can always get it by running the following, as the postgres user,

   SHOW port;
   

   Or,

   $ grep "port =" /etc/postgresql/*/main/postgresql.conf
   

Sidenote: the postgres user

I suggest NOT modifying the postgres user.

1. It's normally locked from the OS. No one is supposed to "log in" to the operating system as postgres. You're supposed to have root to get to authenticate as postgres.
2. It's normally not password protected and delegates to the host operating system. This is a good thing. This normally means in order to log in as postgres which is the PostgreSQL equivalent of SQL Server's SA, you have to have write-access to the underlying data files. And, that means that you could normally wreck havoc anyway.
3. By keeping this disabled, you remove the risk of a brute force attack through a named super-user. Concealing and obscuring the name of the superuser has advantages.

Try this:

data=pd.read_csv('C:\Users\Desktop\Data Exploration.csv')
data.head(5)
first=data['1st Gift']
last=data['Last Gift']
maxi=data['Largest Gift']
l_1=np.mean(first)-3*np.std(first)
u_1=np.mean(first)+3*np.std(first)


m=np.abs(data['1st Gift']-np.mean(data['1st Gift']))>3*np.std(data['1st Gift'])
pd.value_counts(m)
l=first[m]
data.loc[:,'1st Gift'][m==True]=np.mean(data['1st Gift'])+3*np.std(data['1st Gift'])
data['1st Gift'].head()




m=np.abs(data['Last Gift']-np.mean(data['Last Gift']))>3*np.std(data['Last Gift'])
pd.value_counts(m)
l=last[m]
data.loc[:,'Last Gift'][m==True]=np.mean(data['Last Gift'])+3*np.std(data['Last Gift'])
data['Last Gift'].head()

if you are using background then you must use this tag

android:testCursorDrawable="@null" 

The problem was the cuDNN Library for me - for whatever reason cudnn-8.0-windows10-x64-v6.0 was NOT working - I used cudnn-8.0-windows10-x64-v5.1 - ALL GOOD!

My setup working with Win10 64 and the Nvidia GTX780M:

• Be sure you have the lib MSVCP140.DLL by checking your system/path - if not get it here
• Run the windows installer for python 3.5.3-amd64 from here - DO NOT try newer versions as they probably won't work
• Get the cuDNN v5.1 for CUDA 8.0 from here - put it under your users folder or in another known location (you will need this in your path)
• Get CUDA 8.0 x86_64 from here
• Set PATH vars as expected to point at the cuDNN libs and python (the python path should be added during the python install)
• Make sure that ".DLL" is included in your PATHEXT variable
• If you are using tensorflow 1.3 then you want to use cudnn64_6.dll github.com/tensorflow/tensorflow/issues/7705

If you run Windows 32 be sure to get the 32 bit versions of the files mentioned above.

From a practical point of view (summarizing what has been said in many previous answers and related articles), it seems to me that one of the fundamental "purposes" (or usefulness) of the monad is to leverage the dependencies implicit in recursive method invocations aka function composition (i.e. when f1 calls f2 calls f3, f3 needs to be evaluated before f2 before f1) to represent sequential composition in a natural way, especially in the context of a lazy evaluation model (that is, sequential composition as a plain sequence, e.g. "f3(); f2(); f1();" in C - the trick is especially obvious if you think of a case where f3, f2 and f1 actually return nothing [their chaining as f1(f2(f3)) is artificial, purely intended to create sequence]).

This is especially relevant when side-effects are involved, i.e. when some state is altered (if f1, f2, f3 had no side-effects, it wouldn't matter in what order they're evaluated; which is a great property of pure functional languages, to be able to parallelize those computations for example). The more pure functions, the better.

I think from that narrow point of view, monads could be seen as syntactic sugar for languages that favor lazy evaluation (that evaluate things only when absolutely necessary, following an order that does not rely on the presentation of the code), and that have no other means of representing sequential composition. The net result is that sections of code that are "impure" (i.e. that do have side-effects) can be presented naturally, in an imperative manner, yet are cleanly separated from pure functions (with no side-effects), which can be evaluated lazily.

This is only one aspect though, as warned here.

Append Single Element

//Append to the end
arrName.push('newName1');

//Prepend to the start
arrName.unshift('newName1');

//Insert at index 1
arrName.splice(1, 0,'newName1');
//1: index number, 0: number of element to remove, newName1: new element


// Replace index 3 (of exists), add new element otherwise.
arrName[3] = 'newName1';

Append Multiple Elements

//Insert from index number 1
arrName.splice(1, 0,'newElemenet1', 'newElemenet2', 'newElemenet3');
//1: index number from where insert starts, 
//0: number of element to remove, 
//newElemenet1,2,3: new elements

Append array

//join two or more arrays
arrName.concat(newAry1, newAry2);
//newAry1,newAry2: Two different arrays which are to be combined (concatenated) to an existing array

Looks like im very late but for those of you who need to switch to new screen and clear back button stack here is a very simple solution.

startActivity(new Intent(this,your-new-screen.class));
finishAffinity();

The finishAffinity(); method clears back button stack.

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

One of the most direct ways to use optionals is the following:

Assuming xyz is of optional type, like Int? for example.

if let possXYZ = xyz {
    // do something with possXYZ (the unwrapped value of xyz)
} else {
    // do something now that we know xyz is .None
}

This way you can both test if xyz contains a value and if so, immediately work with that value.

With regards to your compiler error, the type UInt8 is not optional (note no '?') and therefore cannot be converted to nil. Make sure the variable you're working with is an optional before you treat it like one.

function resize() {resizeFrame(elemento, margin);};

jQuery.event.add(window, "load", resize);
jQuery.event.add(window, "resize", resize);
function resizeFrame(item, marge) {
  $(item).each(function() {
  var m = marge*2;
  var mw = $(window).width()-m; 
  var mh = $(window).height()-m;
  var w = $('img',this).width();
  var h = $('img',this).height();
  var mr = mh/mw;
  var cr = h/w;
  $('img',this).css({position:'absolute',minWidth:(w-w)+20,minHeight:(h-h)+20,margin:'auto',top:'0',right:'0',bottom:'0',left:'0',padding:marge});
    if(cr < mr){
        var r = mw/w;
        $('img',this).css({width: mw});
        $('img',this).css({height: h*r});
    }else if(cr > mr){
        var r = mh/h;
        $('img',this).css({height: mh});
        $('img',this).css({width: w*r});
    }
  });  
}

The short answer:

Use the click event, which won't fire until after the value has been updated, and fires when you want it to:

<label><input type='checkbox' onclick='handleClick(this);'>Checkbox</label>

function handleClick(cb) {
  display("Clicked, new value = " + cb.checked);
}

Live example | Source

The longer answer:

The change event handler isn't called until the checked state has been updated (live example | source), but because (as Tim Büthe points out in the comments) IE doesn't fire the change event until the checkbox loses focus, you don't get the notification proactively. Worse, with IE if you click a label for the checkbox (rather than the checkbox itself) to update it, you can get the impression that you're getting the old value (try it with IE here by clicking the label: live example | source). This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing.

But you can avoid all of that unpleasantness if you use click instead.

I've used DOM0 handlers (onxyz attributes) because that's what you asked about, but for the record, I would generally recommend hooking up handlers in code (DOM2's addEventListener, or attachEvent in older versions of IE) rather than using onxyz attributes. That lets you attach multiple handlers to the same element and lets you avoid making all of your handlers global functions.

An earlier version of this answer used this code for handleClick:

function handleClick(cb) {
  setTimeout(function() {
    display("Clicked, new value = " + cb.checked);
  }, 0);
}

The goal seemed to be to allow the click to complete before looking at the value. As far as I'm aware, there's no reason to do that, and I have no idea why I did. The value is changed before the click handler is called. In fact, the spec is quite clear about that. The version without setTimeout works perfectly well in every browser I've tried (even IE6). I can only assume I was thinking about some other platform where the change isn't done until after the event. In any case, no reason to do that with HTML checkboxes.

For me I had indicated max-height instead of max-width.

If that is you, go change it !

    @media screen and (max-width: 350px) {    // Not max-height
        .letter{
            font-size:20px;
        }
    }

I want to give a shoutout for using re module for this. Specially in the case of case sensitivity.

We use the option re.IGNORECASE while compiling the regex for use of in production environments with large amounts of data.

>>> import re
>>> m = ['isalnum','isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'ISALNUM', 'ISALPHA', 'ISDIGIT', 'ISLOWER', 'ISSPACE', 'ISTITLE', 'ISUPPER']
>>>
>>>
>>> pattern = re.compile('is')
>>>
>>> [word for word in m if pattern.match(word)]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

However try to always use the in operator for string comparison as detailed in this post

faster-operation-re-match-or-str

Also detailed in the one of the best books to start learning python with

idiomatic-python

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

As of this date, the correct way according to the dynamic routing docs is:

this.$route.params.yourProperty

instead of

this.$route.query.yourProperty

if you wanna ng-model value, if you can write like this in the triggered event: $scope.searchText

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

Code:

num_rows, num_cols = 4, 2
initial_val = 0
matrix = [[initial_val] * num_cols for _ in range(num_rows)]
print(matrix) 
# [[0, 0], [0, 0], [0, 0], [0, 0]]

initial_val must be immutable.

Solution: In order to increase your buffer history on iterm bash terminal you've got two options:

Go to iterm -> Preferences -> Profiles -> Terminal Tab -> Scrollback Buffer (section)

Option 1. select the checkbox Unlimited scrollback

Option 2. type the selected Scrollback lines numbers you'd like your terminal buffer to cache (See image below)

On Jupyter Notebooks on Anaconda, doing this:

%load_ext autoreload
%autoreload 2

produced the message:

The autoreload extension is already loaded. To reload it, use: %reload_ext autoreload

It looks like it's preferable to do:

%reload_ext autoreload
%autoreload 2

It bugged me too to find a solution to mimic interfaces with the lower impacts possible.

One solution could be to make a tool :

/**
@parameter {Array|object} required : method name list or members types by their name
@constructor
*/
let Interface=function(required){
    this.obj=0;
    if(required instanceof Array){
        this.obj={};
        required.forEach(r=>this.obj[r]='function');
    }else if(typeof(required)==='object'){
        this.obj=required;
    }else {
        throw('Interface invalid parameter required = '+required);
    }
};
/** check constructor instance
@parameter {object} scope : instance to check.
@parameter {boolean} [strict] : if true -> throw an error if errors ar found.
@constructor
*/
Interface.prototype.check=function(scope,strict){
    let err=[],type,res={};
    for(let k in this.obj){
        type=typeof(scope[k]);
        if(type!==this.obj[k]){
            err.push({
                key:k,
                type:this.obj[k],
                inputType:type,
                msg:type==='undefined'?'missing element':'bad element type "'+type+'"'
            });
        }
    }
    res.success=!err.length;
    if(err.length){
        res.msg='Class bad structure :';
        res.errors=err;
        if(strict){
            let stk = new Error().stack.split('\n');
            stk.shift();
            throw(['',res.msg,
                res.errors.map(e=>'- {'+e.type+'} '+e.key+' : '+e.msg).join('\n'),
                '','at :\n\t'+stk.join('\n\t')
            ].join('\n'));

        }
    }
    return res;
};

Exemple of use :

// create interface tool
let dataInterface=new Interface(['toData','fromData']);
// abstract constructor
let AbstractData=function(){
    dataInterface.check(this,1);// check extended element
};
// extended constructor
let DataXY=function(){
    AbstractData.apply(this,[]);
    this.xy=[0,0];
};
DataXY.prototype.toData=function(){
    return [this.xy[0],this.xy[1]];
};

// should throw an error because 'fromData' is missing
let dx=new DataXY();

With classes

class AbstractData{
    constructor(){
        dataInterface.check(this,1);
    }
}
class DataXY extends AbstractData{
    constructor(){
        super();
        this.xy=[0,0];
    }
    toData(){
        return [this.xy[0],this.xy[1]];
    }
}

It's still a bit performance consumming and require dependancy to the Interface class, but can be of use for debug or open api.

FirstOrDefault ?

Elem e = enumerable.FirstOrDefault();
//do something with e

I think this would do it...

def validIP(address):
    parts = address.split(".")
    if len(parts) != 4:
        return False
    for item in parts:
        if not 0 <= int(item) <= 255:
            return False
    return True

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)
        .where(predicateResult);

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)
        .getResultList();  

Some notes and some tricks.

The 'official' way to assign result to a variable is with FOR /F though in the other answers is shown how a temporary file can be used also.

For command processing FOR command has two forms depending if the usebackq option is used. In the all examples below the whole output is used without splitting it.

FOR /f "tokens=* delims=" %%A in ('whoami') do @set "I-Am=%%A"
FOR /f "usebackq tokens=* delims=" %%A in (`whoami`) do @set "I-Am=%%A"

and if used directly in the console:

FOR /f "tokens=* delims=" %A in ('whoami') do set "I-Am=%A"
FOR /f "usebackq tokens=* delims=" %A in (`whoami`) do set "I-Am=%A"

%%A is a temporary variable available only on the FOR command context and is called token.The two forms can be useful in case when you are dealing with arguments containing specific quotes. It is especially useful with REPL interfaces of other languages or WMIC. Though in both cases the expression can be put in double quotes and it still be processed.

Here's an example with python (it is possible to transition the expression in the brackets on a separate line which is used for easier reading):

@echo off

for /f "tokens=* delims=" %%a in (
  '"python -c ""print("""Message from python""")"""'
) do (
    echo processed message from python: "%%a"
)

To use an assigned variable in the same FOR block check also the DELAYED EXPANSION

And some tricks

To save yourself from writing all the arguments for the FOR command you can use MACRO for assigning the result to variable:

@echo off

::::: ---- defining the assign macro ---- ::::::::
setlocal DisableDelayedExpansion
(set LF=^
%=EMPTY=%
)
set ^"\n=^^^%LF%%LF%^%LF%%LF%^^"

::set argv=Empty
set assign=for /L %%n in (1 1 2) do ( %\n%
   if %%n==2 (%\n%
      setlocal enableDelayedExpansion%\n%
      for /F "tokens=1,2 delims=," %%A in ("!argv!") do (%\n%
         for /f "tokens=* delims=" %%# in ('%%~A') do endlocal^&set "%%~B=%%#" %\n%
      ) %\n%
   ) %\n%
) ^& set argv=,

::::: -------- ::::::::


:::EXAMPLE
%assign% "WHOAMI /LOGONID",result
echo %result%

the first argument to the macro is the command and the second the name of the variable we want to use and both are separated by , (comma). Though this is suitable only for straight forward scenarios.

If we want a similar macro for the console we can use DOSKEY

doskey assign=for /f "tokens=1,2 delims=," %a in ("$*") do @for /f "tokens=* delims=" %# in ('"%a"') do @set "%b=%#"
rem  -- example --
assign WHOAMI /LOGONID,my-id
echo %my-id%

DOSKEY does accept double quotes as enclosion for arguments so this also is useful for more simple scenarios.

FOR also works well with pipes which can be used for chaining commands (though it is not so good for assigning a variable.

hostname |for /f "tokens=* delims=" %%# in ('more') do @(ping %%#)

Which also can be beautified with macros:

@echo off
:: --- defining chain command macros ---
set "result-as-[arg]:=|for /f "tokens=* delims=" %%# in ('more') do @("
set "[arg]= %%#)"
:::  --------------------------  :::

I needed to switch between two images. With conditional switching between them there was 5sec delay with no image displayed.

I'm using approach from downvoted amos answer. Posting as new answer because it's hard to put code into comment with proper formatting.

Render function:

<View style={styles.logoWrapper}>
  <Image
    style={[styles.logo, loading ? styles.hidden : {}]}
    source={require('./logo.png')} />
  <Image
    style={[styles.logo, loading ? {} : styles.hidden]}
    source={require('./logo_spin.gif')} />
</View>

Styles:

var styles = StyleSheet.create({
  logo: {
    width: 200,
    height: 200,
  },
  hidden: {
    width: 0,
    height: 0,
  },
});

If you didn't want to edit the layer of a UIView, you could always embed the view within another view. The parent view would have its background color set to the border color. It would also be slightly larger, depending upon how wide you want the border to be.

Of course, this only works if your view isn't transparent and you only want a single border color. The OP wanted the border in the view itself, but this may be a viable alternative.

I tried the code provided by Ranadheer Reddy (above) and it worked great. If you’re using a company computer that has a restricted server you may need to change the SMTP port to 25 and leave your username and password blank since they will auto fill by your admin.

Originally, I tried using EASendMail from the nugent package manager, only to realize that it’s a pay for version with 30-day trial. Don’t waist your time with it unless you plan on buying it. I noticed the program ran much faster using EASendMail, but for me, free trumped fast.

Just my 2 cents worth.

Turns out, when the table name is different than the model name, you have to change the annotations to:

@Entity
@Table(name = "table_name")
class WhateverNameYouWant {
    ...

Instead of simply using the @Entity annotation.

What was weird for me, is that the class it was trying to convert to didn't exist. This worked for me.

Get highlighted text this way:

window.getSelection().toString()

and of course a special treatment for ie:

document.selection.createRange().htmlText

Thanks to everyone who answered the question, it really helped clarify things for me. In the end Scott Stanchfield's answer got the closest to how I ended up understanding it, but since I didn't understand him when he first wrote it, I am trying to restate the problem so that hopefully someone else will benefit.

I'm going to restate the question in terms of List, since it has only one generic parameter and that will make it easier to understand.

The purpose of the parametrized class (such as List<Date> or Map<K, V> as in the example) is to force a downcast and to have the compiler guarantee that this is safe (no runtime exceptions).

Consider the case of List. The essence of my question is why a method that takes a type T and a List won't accept a List of something further down the chain of inheritance than T. Consider this contrived example:

List<java.util.Date> dateList = new ArrayList<java.util.Date>();
Serializable s = new String();
addGeneric(s, dateList);

....
private <T> void addGeneric(T element, List<T> list) {
    list.add(element);
}

This will not compile, because the list parameter is a list of dates, not a list of strings. Generics would not be very useful if this did compile.

The same thing applies to a Map<String, Class<? extends Serializable>> It is not the same thing as a Map<String, Class<java.util.Date>>. They are not covariant, so if I wanted to take a value from the map containing date classes and put it into the map containing serializable elements, that is fine, but a method signature that says:

private <T> void genericAdd(T value, List<T> list)

Wants to be able to do both:

T x = list.get(0);

and

list.add(value);

In this case, even though the junit method doesn't actually care about these things, the method signature requires the covariance, which it is not getting, therefore it does not compile.

On the second question,

Matcher<? extends T>

Would have the downside of really accepting anything when T is an Object, which is not the APIs intent. The intent is to statically ensure that the matcher matches the actual object, and there is no way to exclude Object from that calculation.

The answer to the third question is that nothing would be lost, in terms of unchecked functionality (there would be no unsafe typecasting within the JUnit API if this method was not genericized), but they are trying to accomplish something else - statically ensure that the two parameters are likely to match.

EDIT (after further contemplation and experience):

One of the big issues with the assertThat method signature is attempts to equate a variable T with a generic parameter of T. That doesn't work, because they are not covariant. So for example you may have a T which is a List<String> but then pass a match that the compiler works out to Matcher<ArrayList<T>>. Now if it wasn't a type parameter, things would be fine, because List and ArrayList are covariant, but since Generics, as far as the compiler is concerned require ArrayList, it can't tolerate a List for reasons that I hope are clear from the above.

function isEqual(a) {
if (arrayData.length > 0) {
    for (var i in arrayData) {
        if (JSON.stringify(arrayData[i]) === JSON.stringify(a)) {
            alert("Ya existe un registro con esta informacion");
            return false;
        }
    }
}
}

Check this example

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy
    rNext.PasteSpecial xlPasteFormulasAndNumberFormats

    Application.CutCopyMode = False

End Sub

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

Python strings are immutable and hence have more complex handling when talking about its operations. Note that a string with spaces is actually an empty string but has a non-zero size. Let’s see two different methods of checking if string is empty or not: Method #1 : Using Len() Using Len() is the most generic method to check for zero-length string. Even though it ignores the fact that a string with just spaces also should be practically considered as an empty string even its non-zero.

Method #2 : Using not

Not operator can also perform the task similar to Len(), and checks for 0 length string, but same as the above, it considers the string with just spaces also to be non-empty, which should not practically be true.

Good Luck!

Try this. It will work just fine:

int week = Convert.ToInt32(currentDateTime.DayOfWeek);

This works for me.

select * from tablename
order by cast(columnname as int) asc

OMG, a XAND gate does exist. My dad is taking a technological class for a job and there IS an XAND gate. People are saying that both OR and AND are complete opposites, so they expand that to the exclusive-gate logic:

XOR: One or another, but not both.

Xand: One and another, but not both.

This is incorrect. If you're going to change from XOR to XAND, you have to flip every instance of 'AND' and 'OR':

XOR: One or another, but not both.

XAND: One and another, but not one.

So, XAND is true when and only when both inputs are equal, either if the inputs are 0/0 or 1/1

The problem is the blank line you are typing before the else or elif. Pay attention to the prompt you're given. If it is >>>, then Python is expecting the start of a new statement. If it is ..., then it's expecting you to continue a previous statement.

Combining answers from above:

history -w vi ~/.bash_history history -r

This command installs npm package username/package from specific git commit:

npm install https://github.com/username/package#3d0a21cc

Here 3d0a21cc is first 8 characters of commit hash.

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

It's another way of Git telling you:

Hey, I see you made some changes, but keep in mind that when you write pages to my history, those changes won't be in these pages.

Changes to files are not staged if you do not explicitly git add them (and this makes sense).

So when you git commit, those changes won't be added since they are not staged. If you want to commit them, you have to stage them first (ie. git add).

You can use verbatim literals:

const string test = @"Test
123
456
";

But the indentation of the 1st line is tricky/ugly.

One way I like to use is:

select ,COUNT()as VAR1 from Table_Name

group by

order by VAR1 desc

limit 1

git clone -o <sha1-of-the-commit> <repository-url> <local-dir-name>

git uses the word origin in stead of popularly known revision

Following is a snippet from the manual $ git help clone

--origin <name>, -o <name>
    Instead of using the remote name origin to keep track of the upstream repository, use <name>.

DateTime dt = DateTime.Parse("01:00 pm"); //Time in string formate

TimeSpan time = new TimeSpan(); 

time = dt.TimeOfDay;

Console.WriteLine(time);

Result : 13:00:00

As described in Cast Functions and Operators:

The type for the result can be one of the following values:

• BINARY[(N)]
• CHAR[(N)]
• DATE
• DATETIME
• DECIMAL[(M[,D])]
• SIGNED [INTEGER]
• TIME
• UNSIGNED [INTEGER]

Therefore, you should use:

SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT

run cmd.exe and do the following:

> cd "long path name"
> command

Then command.com will come up and display only short paths.

Another way is to call the dir() function (see https://docs.python.org/2/library/functions.html#dir).

a = Animal()
dir(a)   
>>>
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__',
 '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', 
 '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 
 '__weakref__', 'age', 'color', 'kids', 'legs', 'name', 'smell']

Note, that dir() tries to reach any attribute that is possible to reach.

Then you can access the attributes e.g. by filtering with double underscores:

attributes = [attr for attr in dir(a) 
              if not attr.startswith('__')]

This is just an example of what is possible to do with dir(), please check the other answers for proper way of doing this.

Just sharing as this was my solution thanks to Canavar's post.

If you have something like this:

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:

"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:

String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:

"http://localhost:1234/"
"https://www.something.com/"

As apps run in the background anyway. I’m assuming what your really asking is how do you make apps do stuff in the background. The solution below will make your app do stuff in the background after opening the app and after the system has rebooted.

Below, I’ve added a link to a fully working example (in the form of an Android Studio Project)

This subject seems to be out of the scope of the Android docs, and there doesn’t seem to be any one comprehensive doc on this. The information is spread across a few docs.

The following docs tell you indirectly how to do this: https://developer.android.com/reference/android/app/Service.html

https://developer.android.com/reference/android/content/BroadcastReceiver.html

https://developer.android.com/guide/components/bound-services.html

In the interests of getting your usage requirements correct, the important part of this above doc to read carefully is: #Binder, #Messenger and the components link below:

https://developer.android.com/guide/components/aidl.html

Here is the link to a fully working example (in Android Studio format): http://developersfound.com/BackgroundServiceDemo.zip

This project will start an Activity which binds to a service; implementing the AIDL.

This project is also useful to re-factor for the purpose of IPC across different apps.

This project is also developed to start automatically when Android restarts (provided the app has been run at least one after installation and app is not installed on SD card)

When this app/project runs after reboot, it dynamically uses a transparent view to make it look like no app has started but the service of the associated app starts cleanly.

This code is written in such a way that it’s very easy to tweak to simulate a scheduled service.

This project is developed in accordance to the above docs and is subsequently a clean solution.

There is however a part of this project which is not clean being: I have not found a way to start a service on reboot without using an Activity. If any of you guys reading this post have a clean way to do this please post a comment.

I am using Windows 10 Home edition.

I tried various combination,

netsh wlan show drivers
netsh wlan show hostednetwork
netsh wlan set hostednetwork mode=allow ssid=happy key=12345678
netsh wlan start hostednetwork

and also,

Control Panel\Network and Internet\Network Connections\Ethernet Properties\Sharing\Internet Connection Sharing\Allow other network users to connect through this computer Internet connection...

But still cannot activate WiFi hotspot.

While I have given up, somehow I click on Network icon on the taskbar, suddenly I see the buttons:

[ Wi-Fi ] [ Airplane Mode ] [ Mobile hotspot ]

Just like how our mobile phone can enable Mobile hotspot, Windows 10 has Mobile hotspot build-in. Just click on [ Mobile hotspot ] button and it works.

The GWT compiler is doing a lot of code analysis so it is going to be difficult to speed it up. This session from Google IO 2008 will give you a good idea of what GWT is doing and why it does take so long.

My recommendation is for development use Hosted Mode as much as possible and then only compile when you want to do your testing. This does sound like the solution you've come to already, but basically that's why Hosted Mode is there (well, that and debugging).

You can speed up the GWT compile but only compiling for some browsers, rather than 5 kinds which GWT does by default. If you want to use Hosted Mode make sure you compile for at least two browsers; if you compile for a single browser then the browser detection code is optimised away and then Hosted Mode doesn't work any more.

An easy way to configure compiling for fewer browsers is to create a second module which inherits from your main module:

<module rename-to="myproject">
  <inherits name="com.mycompany.MyProject"/>
  <!-- Compile for IE and Chrome -->
  <!-- If you compile for only one browser, the browser detection javascript
       is optimised away and then Hosted Mode doesn't work -->
  <set-property name="user.agent" value="ie6,safari"/>
</module>

If the rename-to attribute is set the same then the output files will be same as if you did a full compile

As of Telegram Desktop 1.3 you can format your messages and add links.

[Ctrl+K] = create link (https://my.website)

Other useful hotkeys are:

[Ctrl+B] = bold
[Ctrl+I] = italic
[Ctrl+Shift+M] = monospace
[Ctrl+Shift+N] = clear formatting

Use splatting.

If you drill down through the abstractions of the IdentityDbContext you'll find that it looks just like your derived DbContext. The easiest route is Olav's answer, but if you want more control over what's getting created and a little less dependency on the Identity packages have a look at my question and answer here. There's a code example if you follow the link, but in summary you just add the required DbSets to your own DbContext subclass.

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

Use regex in data annotation

L = ['L','O','L']
makeitastring = ''.join(map(str, L))

Given the declarations

char *s0 = "hello world";
char s1[] = "hello world";

assume the following hypothetical memory map:

                    0x01  0x02  0x03  0x04
        0x00008000: 'h'   'e'   'l'   'l'
        0x00008004: 'o'   ' '   'w'   'o'
        0x00008008: 'r'   'l'   'd'   0x00
        ...
s0:     0x00010000: 0x00  0x00  0x80  0x00
s1:     0x00010004: 'h'   'e'   'l'   'l'
        0x00010008: 'o'   ' '   'w'   'o'
        0x0001000C: 'r'   'l'   'd'   0x00

The string literal "hello world" is a 12-element array of char (const char in C++) with static storage duration, meaning that the memory for it is allocated when the program starts up and remains allocated until the program terminates. Attempting to modify the contents of a string literal invokes undefined behavior.

The line

char *s0 = "hello world";

defines s0 as a pointer to char with auto storage duration (meaning the variable s0 only exists for the scope in which it is declared) and copies the address of the string literal (0x00008000 in this example) to it. Note that since s0 points to a string literal, it should not be used as an argument to any function that would try to modify it (e.g., strtok(), strcat(), strcpy(), etc.).

The line

char s1[] = "hello world";

defines s1 as a 12-element array of char (length is taken from the string literal) with auto storage duration and copies the contents of the literal to the array. As you can see from the memory map, we have two copies of the string "hello world"; the difference is that you can modify the string contained in s1.

s0 and s1 are interchangeable in most contexts; here are the exceptions:

sizeof s0 == sizeof (char*)
sizeof s1 == 12

type of &s0 == char **
type of &s1 == char (*)[12] // pointer to a 12-element array of char

You can reassign the variable s0 to point to a different string literal or to another variable. You cannot reassign the variable s1 to point to a different array.

Setting the dialog cancelable to be false is enough, and either you touch outside of the alert dialog or click the back button will make the alert dialog disappear. So use this one:

setCancelable(false)

And the other function is not necessary anymore: dialog.setCanceledOnTouchOutside(false);

If you are creating a temporary dialog and wondering there to put this line of code, here is an example:

new AlertDialog.Builder(this)
                        .setTitle("Trial Version")
                        .setCancelable(false)
                        .setMessage("You are using trial version!")
                        .setIcon(R.drawable.time_left)
                        .setPositiveButton(android.R.string.yes, null).show();

If n is 2, it's prime.

If n is 1, it's not prime.

If n is even, it's not prime.

If n is odd, bigger than 2, we must check all odd numbers 3..sqrt(n)+1, if any of this numbers can divide n, n is not prime, else, n is prime.

For better performance i recommend sieve of eratosthenes.

Here is the code sample:

bool is_prime(int n)
{
  if (n == 2) return true;
  if (n == 1 || n % 2 == 0) return false;

  for (int i = 3; i*i < n+1; i += 2) {
      if (n % i == 0) return false;
  }

  return true;
}

There are two pair of modal events, one is "show" and "shown", the other is "hide" and "hidden". As you can see from the name, hide event fires when modal is about the be close, such as clicking on the cross on the top-right corner or close button or so on. While hidden is fired after the modal is actually close. You can test these events your self. For exampel:

$( '#modal' )
   .on('hide', function() {
       console.log('hide');
   })
   .on('hidden', function(){
       console.log('hidden');
   })
   .on('show', function() {
       console.log('show');
   })
   .on('shown', function(){
      console.log('shown' )
   });

And, as for your question, I think you should listen to the 'hide' event of your modal.

The current user's username can be gotten in pure Bash with the ${parameter@operator} parameter expansion (introduced in Bash 4.4):

$ : \\u
$ printf '%s\n' "${_@P}"

The : built-in (synonym of true) is used instead of a temporary variable by setting the last argument, which is stored in $_. We then expand it (\u) as if it were a prompt string with the P operator.

This is better than using $USER, as $USER is just a regular environmental variable; it can be modified, unset, etc. Even if it isn't intentionally tampered with, a common case where it's still incorrect is when the user is switched without starting a login shell (su's default).

For anyone still looking for a simpler method to transfer repos from Gitlab to Github while preserving all history.

Step 1. Login to Github, create a private repo with the exact same name as the repo you would like to transfer.

Step 2. Under "push an existing repository from the command" copy the link of the new repo, it will look something like this:

[email protected]:your-name/name-of-repo.git

Step 3. Open up your local project and look for the folder .git typically this will be a hidden folder. Inside the .git folder open up config.

The config file will contain something like:

[remote "origin"]
url = [email protected]:your-name/name-of-repo.git
fetch = +refs/heads/:refs/remotes/origin/

Under [remote "origin"], change the URL to the one that you copied on Github.

Step 4. Open your project folder in the terminal and run: git push --all. This will push your code to Github as well as all the commit history.

Step 5. To make sure everything is working as expected, make changes, commit, push and new commits should appear on the newly created Github repo.

Step 6. As a last step, you can now archive your Gitlab repo or set it to read only.

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 ;)

By postfixing the URL with ?WSDL

If the URL is for example:

http://webservice.example:1234/foo

You use:

http://webservice.example:1234/foo?WSDL

And the wsdl will be delivered.

Alternatively you could read you csv with header=None and then add it with df.columns:

Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]

Generally to get the current week number (starts from Sunday):

from datetime import *
today = datetime.today()
print today.strftime("%U")

I just want to add that if you don't inheritently know the name of a domain controller, you can get the closest one, pass it's hostname to the -Server argument.

$dc = Get-ADDomainController -DomainName example.com -Discover -NextClosestSite

Get-ADUser -Server $dc.HostName[0] `
    -Filter { EmailAddress -Like "*Smith_Karla*" } `
    -Properties EmailAddress

Be sure to declare HttpHeaders without null values.

    this.http.get('url', {headers: new HttpHeaders({'a': a || '', 'b': b || ''}))

Otherwise, if you try to add a null value to HttpHeaders it will give you an error.

Chrome now supports loading HAR files. Open Chrome, Press F12, Click on the Network Tab. Drag and drop the .har file DONE !

If you want this in order to be able to return the List in a getter it would be better to do:

ImmutableList.copyOf(list);

Add spring.profiles.active=tests in your application.properties file, you can add multiple properties file in your spring boot application like application-stage.properties, application-prod.properties, etc. And you can specify in your application.properties file while file to refer by adding spring.profiles.active=stage or spring.profiles.active=prod

you can also pass the profile at the time running the spring boot application by providing the command:

java -jar-Dspring.profiles.active=localbuild/libs/turtle-rnr-0.0.1-SNAPSHOT.jar

According to the profile name the properties file is picked up, in the above case passing profile local consider the application-local.properties file

Direct answer:

• Use a = operator

We can use the public member function std::vector::operator= of the container std::vector for assigning values from a vector to another.

• Use a constructor function

Besides, a constructor function also makes sense. A constructor function with another vector as parameter(e.g. x) constructs a container with a copy of each of the elements in x , in the same order.

Caution:

• Do not use std::vector::swap

std::vector::swap is not copying a vector to another, it is actually swapping elements of two vectors, just as its name suggests. In other words, the source vector to copy from is modified after std::vector::swap is called, which is probably not what you are expected.

• Deep or shallow copy?

If the elements in the source vector are pointers to other data, then a deep copy is wanted sometimes.

According to wikipedia:

A deep copy, meaning that fields are dereferenced: rather than references to objects being copied, new copy objects are created for any referenced objects, and references to these placed in B.

Actually, there is no currently a built-in way in C++ to do a deep copy. All of the ways mentioned above are shallow. If a deep copy is necessary, you can traverse a vector and make copy of the references manually. Alternatively, an iterator can be considered for traversing. Discussion on iterator is beyond this question.

Using the power of datetime:

from datetime import datetime
date_format = "%m/%d/%Y"
a = datetime.strptime('8/18/2008', date_format)
b = datetime.strptime('9/26/2008', date_format)
delta = b - a
print delta.days # that's it

The required file can be accessed as below from resource folder in scala

val file = scala.io.Source.fromFile(s"src/main/resources/app.config").getLines().mkString

To match the title of this question, the value of the id attribute is:

var myId = $(this).attr('id');
alert( myId );

BUT, of course, the element must already have the id element defined, as:

<option id="opt7" class='select_continent' value='7'>Antarctica</option>

In the OP post, this was not the case.

IMPORTANT:

Note that plain js is faster (in this case):

var myId = this.id
alert(  myId  );

That is, if you are just storing the returned text into a variable as in the above example. No need for jQuery's wonderfulness here.

To answer the question literally (since GitHub is not in the question title), also be aware of this post over on superuser. EDIT: Answer copied here in relevant part, slightly modified for clarity in square brackets:

You're getting rejected because you're trying to delete the branch that your origin has currently "checked out".

If you have direct access to the repo, you can just open up a shell [in the bare repo] directory and use good old git branch to see what branch origin is currently on. To change it to another branch, you have to use git symbolic-ref HEAD refs/heads/another-branch.

In many cases an element must be positioned for z-index to work.

Indeed, applying position: relative to the elements in the question would likely solve the problem (but there's not enough code provided to know for sure).

Actually, position: fixed, position: absolute and position: sticky will also enable z-index, but those values also change the layout. With position: relative the layout isn't disturbed.

Essentially, as long as the element isn't position: static (the default setting) it is considered positioned and z-index will work.

Many answers to "Why isn't z-index working?" questions assert that z-index only works on positioned elements. As of CSS3, this is no longer true.

Elements that are flex items or grid items can use z-index even when position is static.

From the specs:

4.3. Flex Item Z-Ordering

Flex items paint exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

5.4. Z-axis Ordering: the z-index property

The painting order of grid items is exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

Here's a demonstration of z-index working on non-positioned flex items: https://jsfiddle.net/m0wddwxs/

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

With Protractor, you can use the following approach

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain newPageName
browser.wait(EC.urlContains('newPageName'), 10000);

So your code will look something like,

emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');

btnLoginEl.click();

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain efg
ptor.wait(EC.urlContains('efg'), 10000);

expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');

Note: This may not mean that new page has finished loading and DOM is ready. The subsequent 'expect()' statement will ensure Protractor waits for DOM to be available for test.

Reference: Protractor ExpectedConditions

If you don't know exactly how to organize data in Redis, I did some performance tests, including the results parsing. The dictonary I used (d) had 437.084 keys (md5 format), and the values of this form:

{"path": "G:\tests\2687.3575.json",
 "info": {"f": "foo", "b": "bar"},
 "score": 2.5}

First Test (inserting data into a redis key-value mapping):

conn.hmset('my_dict', d)  # 437.084 keys added in 8.98s

conn.info()['used_memory_human']  # 166.94 Mb

for key in d:
    json.loads(conn.hget('my_dict', key).decode('utf-8').replace("'", '"'))
    #  41.1 s

import ast
for key in d:
    ast.literal_eval(conn.hget('my_dict', key).decode('utf-8'))
    #  1min 3s

conn.delete('my_dict')  # 526 ms

Second Test (inserting data directly into Redis keys):

for key in d:
    conn.hmset(key, d[key])  # 437.084 keys added in 1min 20s

conn.info()['used_memory_human']  # 326.22 Mb

for key in d:
    json.loads(conn.hgetall(key)[b'info'].decode('utf-8').replace("'", '"'))
    #  1min 11s

for key in d:
    conn.delete(key)
    #  37.3s

As you can see, in the second test, only 'info' values have to be parsed, because the hgetall(key) already returns a dict, but not a nested one.

And of course, the best example of using Redis as python's dicts, is the First Test

Input the following to your Apache configuration:

php_value memory_limit 2048M

To display the current date function:

Calendar c = Calendar.getInstance();

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String date = df.format(c.getTime());
Date.setText(date);

You must want to import

import java.text.SimpleDateFormat; import java.util.Calendar;

You must want to use

TextView Date;
Date = (TextView) findViewById(R.id.Date);

your nested for loop

 for(int j = 0; j < array2.size(); i++){

is infinite as j will always equal to zero, on the other hand, i will be increased at will in this loop. You get OutOfBoundaryException when i is larger than plusArray.size()

Yes you can use .is(':visible') in jquery. But while the code is running under the safari browser .is(':visible') is won't work.

So please use the below code

if( $(".example").offset().top > 0 )

The above line will work both IE as well as safari also.

Type switches can also be used with reflection stuff:

var str = "hello!"
var obj = reflect.ValueOf(&str)

switch obj.Elem().Interface().(type) {
case string:
    log.Println("obj contains a pointer to a string")
default:
    log.Println("obj contains something else")
}

This does not quite answer the original question, which was for a 70/30 split, but in the special case of a 50/50 split between the components there is a way: place an invisible strut at the center and use it to position the two components of interest.

<RelativeLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <View android:id="@+id/strut"
        android:layout_width="0dp"
        android:layout_height="0dp" 
        android:layout_centerHorizontal="true"/>
    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignRight="@id/strut"
        android:layout_alignParentLeft="true"
        android:text="Left"/> 
    <Button 
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@id/strut"
        android:layout_alignParentRight="true"
        android:text="Right"/>
</RelativeLayout>

As this is a pretty common case, this solution is more than a curiosity. It is a bit of a hack but an efficient one because the empty, zero-sized strut should cost very little.

In general, though, it's best not to expect too much from the stock Android layouts...

No one else has answered the question of what is going on in the example you posted.

import java.lang.reflect.Array;

class Stack<T> {
    public Stack(Class<T> clazz, int capacity) {
        array = (T[])Array.newInstance(clazz, capacity);
    }

    private final T[] array;
}

As others have said generics are "erased" during compilation. So at runtime an instance of a generic doesn't know what its component type is. The reason for this is historical, Sun wanted to add generics without breaking the existing interface (both source and binary).

Arrays on the other hand do know their component type at runtime.

This example works around the problem by having the code that calls the constructor (which does know the type) pass a parameter telling the class the required type.

So the application would construct the class with something like

Stack<foo> = new Stack<foo>(foo.class,50)

and the constructor now knows (at runtime) what the component type is and can use that information to construct the array through the reflection API.

Array.newInstance(clazz, capacity);

Finally we have a type cast because the compiler has no way of knowing that the array returned by Array#newInstance() is the correct type (even though we know).

This style is a bit ugly but it can sometimes be the least bad solution to creating generic types that do need to know their component type at runtime for whatever reason (creating arrays, or creating instances of their component type, etc.).

In order to ensure that the link is opened in the same tab, you should use window.location.replace()

See the example below:

window.location.replace("http://www.w3schools.com");

Source: http://www.w3schools.com/jsref/met_loc_replace.asp

You can test it by using this snipped code:

private static void Main(string[] args)
{
   int threadCount = 0;
   try
   {
      for (int i = 0; i < int.MaxValue; i ++)
      {
         new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
         threadCount ++;
      }
   }
   catch
   {
      Console.WriteLine(threadCount);
      Console.ReadKey(true);
   }
}

Beware of 32-bit and 64-bit mode of application.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

Given input in seconds you can transform to format hh:mm:ss like this :

int hours;
int minutes;
int seconds;
int formatHelper;

int input;


//formatHelper maximum value is 24 hours represented in seconds

formatHelper = input % (24*60*60);

//for example let's say format helper is 7500 seconds

hours = formatHelper/60*60;
minutes = formatHelper/60%60;
seconds = formatHelper%60;

//now operations above will give you result = 2hours : 5 minutes : 0 seconds;

I have used formatHelper since the input can be more then 86 400 seconds, which is 24 hours.

If you want total time of your input represented by hh:mm:ss, you can just avoid formatHelper.

I hope it helps.

I had the same problem and this worked:

sudo modprobe ip_tables
sudo echo 'ip_tables' >> /etc/modules

Nicest solution that I was able to figure out was with bluebird promises. You can just do Promise.resolve(files).each(fs.readFileAsync); which guarantees that promises are resolved sequentially in order.

What git-revert does is create a commit which undoes changes made in a given commit, creating a commit which is reverse (well, reciprocal) of a given commit. Therefore

git revert <SHA-1>

should and does work.

If you want to rewind back to a specified commit, and you can do this because this part of history was not yet published, you need to use git-reset, not git-revert:

git reset --hard <SHA-1>

(Note that --hard would make you lose any non-committed changes in the working directory).

Additional Notes

By the way, perhaps it is not obvious, but everywhere where documentation says <commit> or <commit-ish> (or <object>), you can put an SHA-1 identifier (full or shortened) of commit.

Thanks to this post, I finally found the solution. Here is the code:

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
import android.annotation.TargetApi;

public class Main extends Activity {

    private WebView mWebview ;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        mWebview  = new WebView(this);

        mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript

        final Activity activity = this;

        mWebview.setWebViewClient(new WebViewClient() {
            @SuppressWarnings("deprecation")
            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
            }
            @TargetApi(android.os.Build.VERSION_CODES.M)
            @Override
            public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
                // Redirect to deprecated method, so you can use it in all SDK versions
                onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
            }
        });

        mWebview .loadUrl("http://www.google.com");
        setContentView(mWebview );

    }

}

If you can't change the member variable, then the other way around this is to use powerMockit and call

Second second = mock(Second.class)
when(second.doSecond()).thenReturn("Stubbed Second");
whenNew(Second.class).withAnyArguments.thenReturn(second);

Now the problem is that ANY call to new Second will return the same mocked instance. But in your simple case this will work.

First, install the URL Rewrite from a download or from the Web Platform Installer. Second, restart IIS. And, finally, close IIS and open again. The last step worked for me.

For any javadoc (not just the ones available for download) you can use the DownThemAll addon for Firefox with a suitable renaming mask, for example:

*subdirs*/*name*.*ext*

https://addons.mozilla.org/en-us/firefox/addon/downthemall/

https://www.downthemall.org/main/install-it/downthemall-3-0-7/

Edit: It's possible to use some older versions of the DownThemAll add-on with Pale Moon browser.

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

In the server in .NET 4.0 in web.config you also need to change in the default binding. Set the follwowing 3 parms:

    - Enable transfer of large strings with maxBufferSize, maxReceivedMessageSize and maxStringContentLength
    -->  
   < binding **maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"**>  
      < readerQuotas **maxStringContentLength="2147483647"**/>            
   < /binding>

I fell into this this with using the JQLayout plugin, especially when using nested layouts and modals with Bootstrap 4.

An overriding css needs to be added to correct the behaviour,

I just experienced this same problem with the Laravel 4 php framework which uses the guzzlehttp/guzzle composer package. For some reason, the SSL certificate for mailgun stopped validating suddenly and I got that same "error 60" message.

If, like me, you are on a shared hosting without access to php.ini, the other solutions are not possible. In any case, Guzzle has this client initializing code that would most likely nullify the php.ini effects:

// vendor/guzzlehttp/guzzle/src/Client.php
    $settings = [
        'allow_redirects' => true,
        'exceptions'      => true,
        'decode_content'  => true,
        'verify'          => __DIR__ . '/cacert.pem'
    ];

Here Guzzle forces usage of its own internal cacert.pem file, which is probably now out of date, instead of using the one provided by cURL's environment. Changing this line (on Linux at least) configures Guzzle to use cURL's default SSL verification logic and fixed my problem:

        'verify'          => true

You can also set this to false if you don't care about the security of your SSL connection, but that's not a good solution.

Since the files in vendor are not meant to be tampered with, a better solution would be to configure the Guzzle client on usage, but this was just too difficult to do in Laravel 4.

Hope this saves someone else a couple hours of debugging...

You are not passing your 2D array correctly. This should work for you

int rotateArr(int *arr[])

or

int rotateArr(int **arr) 

or

int rotateArr(int arr[][N]) 

Rather than returning the array pass the target array as argument. See John Bode's answer.

This will update all the rows in that columns if safe mode is not enabled.

UPDATE table SET columnB = columnA;

If safe mode is enabled then you will need to use a where clause. I use primary key as greater than 0 basically all will be updated

UPDATE table SET columnB = columnA where table.column>0;

Judging by your other post: How to Get the inner text of a span in PHP. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).

As for the correct approach to grabbing the span text from the client I recommend Johns answer.

These are a good place to get started.

JavaScript: https://stackoverflow.com/questions/11246/best-resources-to-learn-javascript

PHP: https://stackoverflow.com/questions/772349/what-is-a-good-online-tutorial-for-php

Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/

For a simple java String Array you should try

String arr_str [] = { "value1`", "value2", "value3" };

JSONArray arr_strJson = new JSONArray(Arrays.asList(arr_str));
System.out.println(arr_strJson.toString());

If you have an Generic ArrayList of type String like ArrayList<String>. then you should try

 ArrayList<String> obj_list = new ArrayList<>();
    obj_list.add("value1");
    obj_list.add("value2");
    obj_list.add("value3");
  JSONArray arr_strJson = new JSONArray(obj_list));
  System.out.println(arr_strJson.toString());

The solution in my situation was similar answer to Charles Burns; and the problem was related to SQL code comments.

I was building (or updating, rather) an already-functioning SSRS report with Oracle datasource. I added some more parameters to the report, tested it in Visual Studio, it works great, so I deployed it to the report server, and then when the report is executed the report on the server I got the error message:

"ORA-01008: not all variables bound"

I tried quite a few different things (TNSNames.ora file installed on the server, Removed single line comments, Validate dataset query mapping). What it came down to was I had to remove a comment block directly after the WHERE keyword. The error message was resolved after moving the comment block after the WHERE CLAUSE conditions. I have other comments in the code also. It was just the one after the WHERE keyword causing the error.

SQL with error: "ORA-01008: not all variables bound"...

Here is what the dataset parameter mapping screen looks like.

Hope this helps:

- (void)textViewDidChange:(UITextView *)textView {
  CGSize textSize = textview.contentSize;
  if (textSize != textView.frame.size)
      textView.frame.size = textSize;
}

Here's a complete Java 7 program:

class GETHTTPResource {
  public static void main(String[] args) throws Exception {
    try (java.util.Scanner s = new java.util.Scanner(new java.net.URL("http://tools.ietf.org/rfc/rfc768.txt").openStream())) {
      System.out.println(s.useDelimiter("\\A").next());
    }
  }
}

The new try-with-resources will auto-close the Scanner, which will auto-close the InputStream.

You can use multiprocessing.Process to do exactly that.

Code

import multiprocessing
import time

# bar
def bar():
    for i in range(100):
        print "Tick"
        time.sleep(1)

if __name__ == '__main__':
    # Start bar as a process
    p = multiprocessing.Process(target=bar)
    p.start()

    # Wait for 10 seconds or until process finishes
    p.join(10)

    # If thread is still active
    if p.is_alive():
        print "running... let's kill it..."

        # Terminate - may not work if process is stuck for good
        p.terminate()
        # OR Kill - will work for sure, no chance for process to finish nicely however
        # p.kill()

        p.join()

Laravel >= 5.2:

User::inRandomOrder()->get();

or to get the specific number of records

// 5 indicates the number of records
User::inRandomOrder()->limit(5)->get();
// get one random record
User::inRandomOrder()->first();

or using the random method for collections:

User::all()->random();
User::all()->random(10); // The amount of items you wish to receive

Laravel 4.2.7 - 5.1:

User::orderByRaw("RAND()")->get();

Laravel 4.0 - 4.2.6:

User::orderBy(DB::raw('RAND()'))->get();

Laravel 3:

User::order_by(DB::raw('RAND()'))->get();

Check this article on MySQL random rows. Laravel 5.2 supports this, for older version, there is no better solution then using RAW Queries.

edit 1: As mentioned by Double Gras, orderBy() doesn't allow anything else then ASC or DESC since this change. I updated my answer accordingly.

edit 2: Laravel 5.2 finally implements a wrapper function for this. It's called inRandomOrder().

Okay so little bit of digging and I found these gems from Bill Philips article on RecycleView

RecyclerView can do more than ListView, but the RecyclerView class itself has fewer responsibilities than ListView. Out of the box, RecyclerView does not:

• Position items on the screen
• Animate views
• Handle any touch events apart from scrolling

All of this stuff was baked in to ListView, but RecyclerView uses collaborator classes to do these jobs instead.

The ViewHolders you create are beefier, too. They subclass RecyclerView.ViewHolder, which has a bunch of methods RecyclerView uses. ViewHolders know which position they are currently bound to, as well as which item ids (if you have those). In the process, ViewHolder has been knighted. It used to be ListView’s job to hold on to the whole item view, and ViewHolder only held on to little pieces of it.

Now, ViewHolder holds on to all of it in the ViewHolder.itemView field, which is assigned in ViewHolder’s constructor for you.

In case you were looking for an older version of .NET then use:

Module Module1

    Sub Main()
        Dim arr() As String = {"ravi", "Kumar", "Ravi", "Ramesh"}
        Dim result As New List(Of Integer)
        For i As Integer = 0 To arr.Length
            If arr(i).Contains("ra") Then result.Add(i)
        Next
    End Sub

End Module

The reason "sign" is not included is that if we included every useful one-liner in the list of built-in functions, Python wouldn't be easy and practical to work with anymore. If you use this function so often then why don't you do factor it out yourself? It's not like it's remotely hard or even tedious to do so.

go get will install the package in the first directory listed at GOPATH (an environment variable which might contain a colon separated list of directories). You can use go get -u to update existing packages.

You can also use go get -u all to update all packages in your GOPATH

For larger projects, it might be reasonable to create different GOPATHs for each project, so that updating a library in project A wont cause issues in project B.

Type go help gopath to find out more about the GOPATH environment variable.

You can't have two simultaneous queries because mysqli uses unbuffered queries by default (for prepared statements; it's the opposite for vanilla mysql_query). You can either fetch the first one into an array and loop through that, or tell mysqli to buffer the queries (using $stmt->store_result()).

See here for details.

Try CSS:

<h2 style="color:#069">Process Report</h2>

If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:

<style type="text/css">
h2 {
    color:#069;
}
</style>

Building on top of totiG's awesome answer, I have created an IBDesignable class that makes it extremely easy to customize a UILabel's vertical alignment right from the StoryBoard. Just make sure that you set your UILabel's class to 'VerticalAlignLabel' from the StoryBoard identity inspector. If the vertical alignment doesn't take effect, go to Editor->Refresh All Views which should do the trick.

How it works: Once you set your UILabel's class correctly, the storyboard should show you an input field that takes an integer (alignment code).

Update: I've added support for centered labels ~Sev

Enter 0 for Top Alignment

Enter 1 for Middle Alignment

Enter 2 for Bottom Alignment

Assuming you have referenced and correctly integrated your font to your site (presumably using an @font-face kit) it should be alright to just reference yours the way you do. Presumably it is like this so they have fall backs incase some browsers do not render the fonts correctly

Sorry EMS, but I actually just got another response from the matplotlib mailling list (Thanks goes out to Benjamin Root).

The code I am looking for is adjusting the savefig call to:

fig.savefig('samplefigure', bbox_extra_artists=(lgd,), bbox_inches='tight')
#Note that the bbox_extra_artists must be an iterable

This is apparently similar to calling tight_layout, but instead you allow savefig to consider extra artists in the calculation. This did in fact resize the figure box as desired.

import matplotlib.pyplot as plt
import numpy as np

plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_legend_handles_labels()
lgd = ax.legend(handles, labels, loc='upper center', bbox_to_anchor=(0.5,-0.1))
text = ax.text(-0.2,1.05, "Aribitrary text", transform=ax.transAxes)
ax.set_title("Trigonometry")
ax.grid('on')
fig.savefig('samplefigure', bbox_extra_artists=(lgd,text), bbox_inches='tight')

This produces:

[edit] The intent of this question was to completely avoid the use of arbitrary coordinate placements of arbitrary text as was the traditional solution to these problems. Despite this, numerous edits recently have insisted on putting these in, often in ways that led to the code raising an error. I have now fixed the issues and tidied the arbitrary text to show how these are also considered within the bbox_extra_artists algorithm.

JavaScript:

function submitForm() {
    var data1 = new FormData($('input[name^="file"]'));
    $.each($('input[name^="file"]')[0].files, function(i, file) {
        data1.append(i, file);
    });

    $.ajax({
        url: "<?php echo base_url() ?>employee/dashboard2/test2",
        type: "POST",
        data: data1,
        enctype: 'multipart/form-data',
        processData: false, // tell jQuery not to process the data
        contentType: false // tell jQuery not to set contentType
    }).done(function(data) {
        console.log("PHP Output:");
        console.log(data);
    });
    return false;
}

PHP:

public function upload_file() {
    foreach($_FILES as $key) {
        $name = time().$key['name'];
        $path = 'upload/'.$name;
        @move_uploaded_file($key['tmp_name'], $path);
    }
}

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

FWIW, I had what I think is a related problem and came up with a workaround: I wrote a Chrome Extension that did an document.execCommand('paste') into a textarea with focus on window unload in order to populate the element with the system clipboard contents. This worked 100% of the time manually, but the execCommand returned false almost all the time when run under Selenium.

I added a driver.refresh() after the initial driver.get( myChromeExtensionURL ), and now it works 100% of the time. This was with Selenium driver version 2.16.333243 and Chrome version 43 on Mac OS 10.9.

When I was researching the problem, I didn't see any mentions of this workaround, so I thought I'd document my discovery for those following in my Selenium/focus/execCommand('paste') footsteps.

Webkit is the html/css rendering engine used in Apple's Safari browser, and in Google's Chrome. css values prefixes with -webkit- are webkit-specific, they're usually CSS3 or other non-standardised features.

to answer update 2 w3c is the body that tries to standardize these things, they write the rules, then programmers write their rendering engine to interpret those rules. So basically w3c says DIVs should work "This way" the engine-writer then uses that rule to write their code, any bugs or mis-interpretations of the rules cause the compatibility issues.

Your original code uses FileInputStream, which is for accessing file system hosted files.

The constructor you used will attempt to locate a file named a.txt in the www.somewebsite.com subfolder of the current working directory (the value of system property user.dir). The name you provide is resolved to a file using the File class.

URL objects are the generic way to solve this. You can use URLs to access local files but also network hosted resources. The URL class supports the file:// protocol besides http:// or https:// so you're good to go.

By using following code you can copy any class object to another class object for same name and same type of properties.

public class CopyClass
{
    /// <summary>
    /// Copy an object to destination object, only matching fields will be copied
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="sourceObject">An object with matching fields of the destination object</param>
    /// <param name="destObject">Destination object, must already be created</param>
    public static void CopyObject<T>(object sourceObject, ref T destObject)
    {
        //  If either the source, or destination is null, return
        if (sourceObject == null || destObject == null)
            return;

        //  Get the type of each object
        Type sourceType = sourceObject.GetType();
        Type targetType = destObject.GetType();

        //  Loop through the source properties
        foreach (PropertyInfo p in sourceType.GetProperties())
        {
            //  Get the matching property in the destination object
            PropertyInfo targetObj = targetType.GetProperty(p.Name);
            //  If there is none, skip
            if (targetObj == null)
                continue;

            //  Set the value in the destination
            targetObj.SetValue(destObject, p.GetValue(sourceObject, null), null);
        }
    }
}

Call Method Like,

ClassA objA = new ClassA();
ClassB objB = new ClassB();

CopyClass.CopyObject(objOfferMast, ref objB);

It will copy objA into objB.

Taking a column is easy with the map function.

// a two-dimensional array
var two_d = [[1,2,3],[4,5,6],[7,8,9]];

// take the third column
var col3 = two_d.map(function(value,index) { return value[2]; });

Why bother with the slice at all? Just filter the matrix to find the rows of interest.

var interesting = two_d.filter(function(value,index) {return value[1]==5;});
// interesting is now [[4,5,6]]

Sadly, filter and map are not natively available on IE9 and lower. The MDN documentation provides implementations for browsers without native support.

Its a trick not a proper method.

For those wanting a simple solution without jQuery, here's a way.

textarea and message container to put in your form:

<textarea onKeyUp="count_it()" id="text" name="text"></textarea>
Length <span id="counter"></span>

JavaScript:

<script>
function count_it() {
    document.getElementById('counter').innerHTML = document.getElementById('text').value.length;
}
count_it();
</script>

The script counts the characters initially and then for every keystroke and puts the number in the counter span.

Some browsers support Array.indexOf().

If not, you could augment the Array object via its prototype like so...

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(searchElement /*, fromIndex */)
  {
    "use strict";

    if (this === void 0 || this === null)
      throw new TypeError();

    var t = Object(this);
    var len = t.length >>> 0;
    if (len === 0)
      return -1;

    var n = 0;
    if (arguments.length > 0)
    {
      n = Number(arguments[1]);
      if (n !== n) // shortcut for verifying if it's NaN
        n = 0;
      else if (n !== 0 && n !== (1 / 0) && n !== -(1 / 0))
        n = (n > 0 || -1) * Math.floor(Math.abs(n));
    }

    if (n >= len)
      return -1;

    var k = n >= 0
          ? n
          : Math.max(len - Math.abs(n), 0);

    for (; k < len; k++)
    {
      if (k in t && t[k] === searchElement)
        return k;
    }
    return -1;
  };
}

Besides being easier to read (for many people), list comprehensions win the speed race, too:

$ python2.6 -m timeit '[x.lower() for x in ["A","B","C"]]'
1000000 loops, best of 3: 1.03 usec per loop
$ python2.6 -m timeit '[x.upper() for x in ["a","b","c"]]'
1000000 loops, best of 3: 1.04 usec per loop

$ python2.6 -m timeit 'map(str.lower,["A","B","C"])'
1000000 loops, best of 3: 1.44 usec per loop
$ python2.6 -m timeit 'map(str.upper,["a","b","c"])'
1000000 loops, best of 3: 1.44 usec per loop

$ python2.6 -m timeit 'map(lambda x:x.lower(),["A","B","C"])'
1000000 loops, best of 3: 1.87 usec per loop
$ python2.6 -m timeit 'map(lambda x:x.upper(),["a","b","c"])'
1000000 loops, best of 3: 1.87 usec per loop

Regarding the suggestion So I would suggest that you use WebClient and investigate the causes of the 30 second delay.

From the answers for the question System.Net.WebClient unreasonably slow

Try setting Proxy = null;

WebClient wc = new WebClient(); wc.Proxy = null;

Quick Fix- This worked in Eclipse - Right Click on project -> Properties -> Java Build Path (Tab) -> Add External JARs -> locate the servlet api jar implementation (if Tomcat - its named servlet-api.jar) -> click OK. That's it !!

Using below code

-Djavax.net.ssl.keyStoreType=pkcs12

or

System.setProperty("javax.net.ssl.keyStore", pathToKeyStore);

is not at all required. Also there is no need to create your own custom SSL factory.

I also encountered the same issue, in my case there was a issue that complete certificate chain was not imported into truststores. Import certificates using keytool utility right fom root certificate, also you can open cacerts file in notepad and see if the complete certificate chain is imported or not. Check against the alias name you have provided while importing certificates, open the certificates and see how many does it contains, same number of certificates should be there in cacerts file.

Also cacerts file should be configured in the server you are running your application, the two servers will authenticate each other with public/private keys.

I am running on FreeBSD 11.1, the freebsd jail virtualization concept makes the operating system optimal. The current version of Git I am using is 2.15.1, I also prefer to run everything on shell scripts. With that in mind I modified the suggestions above as followed:

git push: .git/hooks/pre-commit

#! /bin/sh -
#
# A hook script called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if it wants
# to stop the commit.

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

# Clear the permissions database file
> $DATABASE;

printf "Backing-up file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
for FILE in $(git ls-files);
do
   # Save the permissions of all the files in the index
    printf "%s;%s\n" $FILE $(stat -f "%Lp;%u;%g" $FILE) >> $DATABASE;
done
IFS=$OLDIFS;

# Add the permissions database file to the index
git add $DATABASE;

printf "OK\n";

git pull: .git/hooks/post-merge

#! /bin/sh -

SELF_DIR=$(git rev-parse --show-toplevel);
DATABASE=$SELF_DIR/.permissions;

printf "Restoring file permissions...\n";

OLDIFS=$IFS;
IFS=$'\n';
while read -r LINE || [ -n "$LINE" ];
do
   FILE=$(printf "%s" $LINE | cut -d ";" -f 1);
   PERMISSIONS=$(printf "%s" $LINE | cut -d ";" -f 2);
   USER=$(printf "%s" $LINE | cut -d ";" -f 3);
   GROUP=$(printf "%s" $LINE | cut -d ";" -f 4);

   # Set the file permissions
   chmod $PERMISSIONS $FILE;

   # Set the file owner and groups
   chown $USER:$GROUP $FILE;

done < $DATABASE
IFS=$OLDIFS

pritnf "OK\n";

exit 0;

If for some reason you need to recreate the script the .permissions file output should have the following format:

.gitignore;644;0;0

For a .gitignore file with 644 permissions given to root:wheel

Notice I had to make a few changes to the stat options.

Enjoy,

I followed the solution by poke with a minor adjustment in the end. My steps follow
- git fetch --prune;
- git branch -a printing the following
    master
    branch
    remotes/origin/HEAD -> origin/master
    remotes/origin/master
    remotes/origin/branch (remote branch to remove)
- git push origin --delete branch.
Here, the branch to remove is not named as remotes/origin/branch but simply branch. And the branch is removed.

In order to unit test code that relies on your database you need to setup a database or mock for each and every test.

1. Having a database (real or mocked) with a single state for all your tests will bite you quickly; you cannot test all records are valid and some aren't from the same data.
2. Setting up an in-memory database in a OneTimeSetup will have issues where the old database is not cleared down before the next test starts up. This will show as tests working when you run them individually, but failing when you run them all.
3. A Unit test should ideally only set what affects the test

I am working in an application that has a lot of tables with a lot of connections and some massive Linq blocks. These need testing. A simple grouping missed, or a join that results in more than 1 row will affect results.

To deal with this I have setup a heavy Unit Test Helper that is a lot of work to setup, but enables us to reliably mock the database in any state, and running 48 tests against 55 interconnected tables, with the entire database setup 48 times takes 4.7 seconds.

Here's how:

1. In the Db context class ensure each table class is set to virtual

   public virtual DbSet<Branch> Branches { get; set; }
   public virtual DbSet<Warehouse> Warehouses { get; set; }
   

2. In a UnitTestHelper class create a method to setup your database. Each table class is an optional parameter. If not supplied, it will be created through a Make method

   internal static Db Bootstrap(bool onlyMockPassedTables = false, List<Branch> branches = null, List<Products> products = null, List<Warehouses> warehouses = null)
   {
       if (onlyMockPassedTables == false) {
           branches ??= new List<Branch> { MakeBranch() };
           warehouses ??= new List<Warehouse>{ MakeWarehouse() };
       }
   

3. For each table class, each object in it is mapped to the other lists

       branches?.ForEach(b => {
           b.Warehouse = warehouses.FirstOrDefault(w => w.ID == b.WarehouseID);
       });
   
       warehouses?.ForEach(w => {
           w.Branches = branches.Where(b => b.WarehouseID == w.ID);
       });
   

4. And add it to the DbContext

        var context = new Db(new DbContextOptionsBuilder<Db>().UseInMemoryDatabase(Guid.NewGuid().ToString()).Options);
        context.Branches.AddRange(branches);
        context.Warehouses.AddRange(warehouses);
        context.SaveChanges();
        return context;
    }
   

5. Define a list of IDs to make is easier to reuse them and make sure joins are valid

    internal const int BranchID = 1;
    internal const int WarehouseID = 2;
   

6. Create a Make for each table to setup the most basic, but connected version it can be

    internal static Branch MakeBranch(int id = BranchID, string code = "The branch", int warehouseId = WarehouseID) => new Branch { ID = id, Code = code, WarehouseID = warehouseId };
    internal static Warehouse MakeWarehouse(int id = WarehouseID, string code = "B", string name = "My Big Warehouse") => new Warehouse { ID = id, Code = code, Name = name };
   

It's a lot of work, but it only needs doing once, and then your tests can be very focused because the rest of the database will be setup for it.

[Test]
[TestCase(new string [] {"ABC", "DEF"}, "ABC", ExpectedResult = 1)]
[TestCase(new string [] {"ABC", "BCD"}, "BC", ExpectedResult = 2)]
[TestCase(new string [] {"ABC"}, "EF", ExpectedResult = 0)]
[TestCase(new string[] { "ABC", "DEF" }, "abc", ExpectedResult = 1)]
public int Given_SearchingForBranchByName_Then_ReturnCount(string[] codesInDatabase, string searchString)
{
    // Arrange
    var branches = codesInDatabase.Select(x => UnitTestHelpers.MakeBranch(code: $"qqqq{x}qqq")).ToList();
    var db = UnitTestHelpers.Bootstrap(branches: branches);
    var service = new BranchService(db);

    // Act
    var result = service.SearchByName(searchString);

    // Assert
    return result.Count();
}

            return objcity;

Assuming you're using jQuery..

var input = '19 51 2.108997\n20 47 2.1089';
var lines = input.split('\n');
var output = '';
$.each(lines, function(key, line) {
    var parts = line.split(' ');
    output += '<span>' + parts[0] + ' ' + parts[1] + '</span><span>' + parts[2] + '</span>\n';
});
$(output).appendTo('body');

Most likely you have some formatting extension installed, e.g. JS-CSS-HTML Formatter.

If it is the case, then just open Command Palette, type "Formatter" and select Formatter Config. Then edit the value of "indent_size" as you like.

P.S. Don't forget to restart Visual Studio Code after editing :)

For whatever reason, I could not get any of the above solutions to work. (Still can't.)

What I did instead was to include the jar in my project (blech) and then create a "system" dependency for it that indicates the path to the jar. It's probably not the RIGHT way to do it, but it does work. And it eliminates the need for the other developers on the team (or the guy setting up the build server) to put the jar in their local repositories.

UPDATE: This solution works for me when I run Hibernate Tools. It does NOT appear to work for building the WAR file, however. It doesn't include the ojdbc6.jar file in the target WAR file.

1) Create a directory called "lib" in the root of your project.

2) Copy the ojdbc6.jar file there (whatever the jar is called.)

3) Create a dependency that looks something like this:

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc</artifactId>
    <version>14</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/ojdbc6.jar</systemPath> <!-- must match file name -->
</dependency>

Ugly, but works for me.

To include the files in the war file add the following to your pom

<build>
    <finalName>MyAppName</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>

                        <targetPath>WEB-INF/classes</targetPath>
                        <includes>
                            <include>**/*.properties</include>

                        </includes>
                    </resource>
                    <resource>

                            <include>**/*.jar</include>
                        </includes>
                    </resource>
                </webResources>

In java-8, they introduced the method removeIf which takes a Predicate as parameter.

So it will be easy as:

List<String> list = new ArrayList<>(Arrays.asList("How are you",
                                                  "How you doing",
                                                  "Joe",
                                                  "Mike"));
list.removeIf(s -> !s.contains("How"));

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Even without connection-sharing, you can still use the psftp or pscp from Windows command line.

See How to use PSCP to copy file from Unix machine to Windows machine ...?

Note that the scp is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).

If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop (what typically resolves to a path like C:\Users\username\Desktop).

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.

(I'm the author of WinSCP)

Try to update your compiler, I'm using GCC 4.7 on Windows 7 Starter x86 with MinGW and it compiles fine with the same options both in C99 and C11.

Try:

import numpy as np
dist = np.array([1,2,3,4,5])
r = 2
dr = 3
np.where(np.logical_and(dist> r, dist<=r+dr))

Output: (array([2, 3]),)

You can see Logic functions for more details.

Instead of looking for ways to decode a5 (Yen ¥) or 96 (en-dash –), tell MySQL that your client is encoded "latin1", but you want "utf8" in the database.

See details in Trouble with UTF-8 characters; what I see is not what I stored

To make reading of this page more valuable (for future search results) I made a list of libraries known to me.. As @CommonsWare mentioned there are super-similar questions/answers.. Anyway some libraries that can be used for making charts are:

Open Source:

• AnyChart (Free for non-commercial, Paid for commercial)
• MPAndroidChart
• Holo Graph Library
• aChartEngine
• ChartView
• aFreeChart
• ChartDroid
• charts4j
• GraphView
• AndroidPlot
• Drawing the 3D piechart Using Google chart Api
• WilliamChart
• HelloCharts
• ChartProgressBar
• Plot.ly

Paid:

• aiCharts
• RChart (pre Honeycomb - Api 11 UI)
• ShinobiControls **
• Steema TeeChart **
• Orson Charts (3D charts for Android)
• Telerik Rad Chart
• SciChart (Realtime Charts for Android)

** - means I didn't try those so I can't really recommend it but other users suggested it..

The problem has to do with the async attribute in the script tag. The Callback Function is trying to call "initMap()" when it doesn't really exists by the time the request finished.

To solve this I placed the Goole Maps Api Script bellow the script where my initMap function was declared.

Hope this helps

According to the CI docs (CodeIgniter Email Library)...

If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called the email.php, add the $config array in that file. Then save the file at config/email.php and it will be used automatically. You will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.

I was able to get this to work by putting all the settings into application/config/email.php.

$config['useragent'] = 'CodeIgniter';
$config['protocol'] = 'smtp';
//$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'YOURPASSWORDHERE';
$config['smtp_port'] = 465; 
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;

Then, in one of the controller methods I have something like:

$this->load->library('email'); // Note: no $config param needed
$this->email->from('[email protected]', '[email protected]');
$this->email->to('[email protected]');
$this->email->subject('Test email from CI and Gmail');
$this->email->message('This is a test.');
$this->email->send();

Also, as Cerebro wrote, I had to uncomment out this line in my php.ini file and restart PHP:

extension=php_openssl.dll

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

Changing this line:

var doc = new jsPDF('L', 'px', [w, h]);
var doc = new jsPDF('L', 'pt', [w, h]);

To fix the dimensions.

Really late reply for me, but I just suffered the pain of this problem as well.

What fixed it for me (after trying the Axis label settings and intervals from those screens, none of which worked!) was select the Horizontal Axis, then when you can see all the properties find Labels, and change LabelInterval to 1.

For some reason when I set this from the pop up properties screens it either never 'stuck' or it changes a slightly different value that didn't fix my issue.

I have to write a whole answer separately since it's hard to add a comment so long to the second answer.

I'm sorry to say this, but the second answer above doesn't work right.

The following three scenarios will show my point:

Scenario 1: Before the following way was deprecated,

  $(window).load(function () {
     alert("Window Loaded.");
  });

if we execute the following two queries:

<script>
   $(window).load(function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

the alert (Dom Loaded.) from the second query will show first, and the one (Window Loaded.) from the first query will show later, which is the way it should be.

Scenario 2: But if we execute the following two queries like the second answer above suggests:

<script>
   $(window).ready(function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

the alert (Window Loaded.) from the first query will show first, and the one (Dom Loaded.) from the second query will show later, which is NOT right.

Scenario 3: On the other hand, if we execute the following two queries, we'll get the correct result:

<script>
   $(window).on("load", function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

that is to say, the alert (Dom Loaded.) from the second query will show first, and the one (Window Loaded.) from the first query will show later, which is the RIGHT result.

In short, the FIRST answer is the CORRECT one:

$(window).on('load', function () {
  alert("Window Loaded.");
});

Use strcmp.

This is in string.h library, and is very popular. strcmp return 0 if the strings are equal. See this for an better explanation of what strcmp returns.

Basically, you have to do:

while (strcmp(check,input) != 0)

or

while (!strcmp(check,input))

or

while (strcmp(check,input))

You can check this, a tutorial on strcmp.

Excellent answers - here's the D3 version for anyone looking:

<select id="sel">
    <option>Cat</option>
    <option>Dog</option>
    <option>Fish</option>
</select>
<script>
    d3.select('#sel').property('value', 'Fish');

I like Clay Eclipse plugin. I've only used it with MySQL, but it claims Firebird support.

For future Googlers who choose NDK approach - i find reliable mentioned stackblur algorithm. I found C++ implementation which does not rely on SSE here - http://www.antigrain.com/__code/include/agg_blur.h.html#stack_blur_rgba32 which contains some optimizations using static tables like:

static unsigned short const stackblur_mul[255] =

I made modification of stackblur algorithm for multi-core systems - it can be found here http://vitiy.info/stackblur-algorithm-multi-threaded-blur-for-cpp/ As more and more devices have 4 cores - optimizations give 4x speed benefit.

Make sure the scp command is available on both sides - both on the client and on the server.

BOTH Server and Client, otherwise you will encounter this kind of (weird)error message on your client: scp: command not found or something similar even though though you have it all configured locally.

Just pass it in, like this:

Game(list_a, list_b, Rule1)

and then your Game function could look something like this (still pseudocode):

def Game(listA, listB, rules=None):
    if rules:
        # do something useful
        # ...
        result = rules(variable) # this is how you can call your rule
    else:
        # do something useful without rules

Most easy way..

//div[@class="Test"]

Assuming you want to find <div class="Test"> as described.

These are known errors from libGL and libstdc++

You can quick fix this by change to use Software for Emulated Performance Graphics option, in the AVD settings.

Or try to use the libstdc++.so.6 (which is available in your system) instead of the one bundled inside Android SDK. There are 2 ways to replace it:

• The emulator has a switch -use-system-libs. You can found it here: ~/Android/Sdk/tools/emulator -avd Nexus_5_API_23 -use-system-libs.

  This option force Linux emulator to load the system libstdc++ (but not Qt libraries), in cases where the bundled ones (from Android SDK) prevent it from loading or working correctly. See this commit

• Alternatively you can set the ANDROID_EMULATOR_USE_SYSTEM_LIBS environment variable to 1 for your user/system.

  This has the benefit of making sure that the emulator will work even if you launched it from within Android Studio.

See: libGL error and libstdc++: Cannot launch AVD in emulator - Issue Tracker

Because copying big objects all over the places wastes time and memory.

Using inline styles:

<input type="text" style="text-align: right"/>

or, put it in a style sheet, like so:

<style>
   .rightJustified {
        text-align: right;
    }
</style>

and reference the class:

<input type="text" class="rightJustified"/>

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

I just tried all of these, and for IE11, the only thing that seems to work is disabled="true". Values of disabled or no value given didnt work. As a matter of fact, the jsp got an error that equal is required for all fields, so I had to specify disabled="true" for this to work.

you can use log4net.Filter.LevelMatchFilter. other options can be found at log4net tutorial - filters

in ur appender section add

<filter type="log4net.Filter.LevelMatchFilter">
    <levelToMatch value="Info" />
    <acceptOnMatch value="true" />
</filter>

the accept on match default is true so u can leave it out but if u set it to false u can filter out log4net filters

SELECT * FROM sample_table WHERE last_visit = DATE_FORMAT('2014-11-24 10:48:09','%Y-%m-%d %H:%i:%s')

this for datetime format in mysql using DATE_FORMAT(date,format).

There used to be a statement in the SQLite documentation that the practical size limit of a database file was a few dozen GB:s. That was mostly due to the need for SQLite to "allocate a bitmap of dirty pages" whenever you started a transaction. Thus 256 byte of RAM were required for each MB in the database. Inserting into a 50 GB DB-file would require a hefty (2^8)*(2^10)=2^18=256 MB of RAM.

But as of recent versions of SQLite, this is no longer needed. Read more here.

I felt the below approach is very easy.

I have declared an interface for callback

public interface AsyncResponse {
    void processFinish(Object output);
}

Then created asynchronous Task for responding all type of parallel requests

 public class MyAsyncTask extends AsyncTask<Object, Object, Object> {

    public AsyncResponse delegate = null;//Call back interface

    public MyAsyncTask(AsyncResponse asyncResponse) {
        delegate = asyncResponse;//Assigning call back interfacethrough constructor
    }

    @Override
    protected Object doInBackground(Object... params) {

    //My Background tasks are written here

      return {resutl Object}

    }

    @Override
    protected void onPostExecute(Object result) {
        delegate.processFinish(result);
    }

}

Then Called the asynchronous task when clicking a button in activity Class.

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        Button mbtnPress = (Button) findViewById(R.id.btnPress);

        mbtnPress.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                MyAsyncTask asyncTask =new MyAsyncTask(new AsyncResponse() {

                    @Override
                    public void processFinish(Object output) {
                        Log.d("Response From Asynchronous task:", (String) output);          
                        mbtnPress.setText((String) output);
                    }
                });
                asyncTask.execute(new Object[] { "Youe request to aynchronous task class is giving here.." });

            }
        });
    }
}

Thanks

In fact, in R, this operation is very easy:

If the matrix 'a' contains some NaN, you just need to use the following code to replace it by 0:

a <- matrix(c(1, NaN, 2, NaN), ncol=2, nrow=2)
a[is.nan(a)] <- 0
a

If the data frame 'b' contains some NaN, you just need to use the following code to replace it by 0:

#for a data.frame: 
b <- data.frame(c1=c(1, NaN, 2), c2=c(NaN, 2, 7))
b[is.na(b)] <- 0
b

Note the difference is.nan when it's a matrix vs. is.na when it's a data frame.

Doing

#...
b[is.nan(b)] <- 0
#...

yields: Error in is.nan(b) : default method not implemented for type 'list' because b is a data frame.

Note: Edited for small but confusing typos

Usually it's because of sdk versions and/or dependencies.

For Cordova developers, put your dependencies settings in "project.properties" file under CORDOVA_PROJECT_ROOT/platforms/android/ folder, like this:

target=android-26
android.library.reference.1=CordovaLib
android.library.reference.2=app
cordova.system.library.1=com.android.support:support-v4:26.1.0
cordova.gradle.include.2=cordova-plugin-googlemaps/app-tbxml-android.gradle
cordova.system.library.3=com.android.support:support-core-utils:26.1.0
cordova.system.library.4=com.google.android.gms:play-services-maps:15.0.0
cordova.system.library.5=com.google.android.gms:play-services-location:15.0.0

So if you use CLI "cordova build", it will overwrite the dependencies section:

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START 
   /* section being overwritten by cordova, referencing project.properties */
...
    // SUB-PROJECT DEPENDENCIES END
}

If you are using proper libraries and its versions in project.properties, you should be fine.

I stopped MySQL sudo service mysql stop and then started xammp sudo /opt/lampp/lampp start and it worked!

According to RFC 4329 the correct MIME type for JavaScript should be application/javascript. Howerver, older IE versions choke on this since they expect text/javascript.
