from the command line type:

mvn eclipse:eclipse

this will add all the dependencies you have in your pom.xml into eclipse...

however, if you haven't done any of this before you may need to do one other, one time only step.

Close eclipse, then run the following command from the shell:

mvn -Declipse.workspace=<eclipse workspace> eclipse:add-maven-repo

sample:

mvn -Declipse.workspace=/home/ft/workspaces/wksp1/ eclipse:add-maven-repo

Tested answer:

In the .view-row css, change:

display:table-row;

to:

display:table

and get rid of "float". Everything will work as expected.

As it has been suggested in the comments, there is no need for a wrapping table. CSS allows for omitting levels of the tree structure (in this case rows) that are implicit. The reason your code doesn't work is that "width" can only be interpreted at the table level, not at the table-row level. When you have a "table" and then "table-cell"s directly underneath, they're implicitly interpreted as sitting in a row.

Working example:

<div class="view">
    <div>Type</div>
    <div>Name</div>                
</div>

with css:

.view {
  width:100%;
  display:table;
}

.view > div {
  width:50%;
  display: table-cell;
}

The reason why has to do with the type system. C/C++ doesn't really support strings as a type. It does support the idea of a constant char array but it doesn't really fully understand the notion of a string.

In order to generate the code for a switch statement the compiler must understand what it means for two values to be equal. For items like ints and enums, this is a trivial bit comparison. But how should the compiler compare 2 string values? Case sensitive, insensitive, culture aware, etc ... Without a full awareness of a string this cannot be accurately answered.

Additionally, C/C++ switch statements are typically generated as branch tables. It's not nearly as easy to generate a branch table for a string style switch.

I was trying to figure out if it's possible to browse the code of an earlier commit like you can on GitHub and it brought me here. I used the information I found here, and after fiddling around with the urls, I actually found a way to browse code of old commits as well. Even though the question/answer is about downloading the code of an earlier commit, I thought I'd just add an answer for browsing the code also.

When you're browsing your code the URL is something like:

https://bitbucket.org/user/repo/src/

and by adding a commit hash at the end like this:

https://bitbucket.org/user/repo/src/a0328cb

You can browse the code at the point of that commit. I don't understand why there's no dropdown box for choosing a commit directly, the feature is already there. Strange.

To run usually click and it should run, that is if you have java installed. If not get java from here Sorry thought it was more general open a command prompt and type java -jar jbpm-installer-3.2.7.jar

It's not that above answers are incorrect, but I find this code extremely easy to understand and therefore I am sharing it here with everyone. And there is also the check for WRITE_CONTACTS permission.

Here is the complete code for how to add phone number, email, website etc to an existing contact.

public static void addNumberToContact(Context context, Long contactRawId, String number) throws RemoteException, OperationApplicationException {
    addInfoToAddressBookContact(
            context,
            contactRawId,
            ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Phone.TYPE,
            ContactsContract.CommonDataKinds.Phone.TYPE_OTHER,
            number
    );
}

public static void addEmailToContact(Context context, Long contactRawId, String email) throws RemoteException, OperationApplicationException {
    addInfoToAddressBookContact(
            context,
            contactRawId,
            ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
            ContactsContract.CommonDataKinds.Email.ADDRESS,
            ContactsContract.CommonDataKinds.Email.TYPE,
            ContactsContract.CommonDataKinds.Email.TYPE_OTHER,
            email
    );
}

public static void addURLToContact(Context context, Long contactRawId, String url) throws RemoteException, OperationApplicationException {
    addInfoToAddressBookContact(
            context,
            contactRawId,
            ContactsContract.CommonDataKinds.Website.CONTENT_ITEM_TYPE,
            ContactsContract.CommonDataKinds.Website.URL,
            ContactsContract.CommonDataKinds.Website.TYPE,
            ContactsContract.CommonDataKinds.Website.TYPE_OTHER,
            url
    );
}

private static void addInfoToAddressBookContact(Context context, Long contactRawId, String mimeType, String whatToAdd, String typeKey, int type, String data) throws RemoteException, OperationApplicationException {
    if(ActivityCompat.checkSelfPermission(context, Manifest.permission.WRITE_CONTACTS) == PackageManager.PERMISSION_DENIED) {
        return;
    }
    ArrayList<ContentProviderOperation> ops = new ArrayList<>();
    ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
            .withValue(ContactsContract.Data.RAW_CONTACT_ID, contactRawId)
            .withValue(ContactsContract.Data.MIMETYPE, mimeType)
            .withValue(whatToAdd, data)
            .withValue(typeKey, type)
            .build());
    getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
}

I had a similar problem in revamping a web site in Dreamweaver. The site structure is based on a complex set of tables, and this video was in one of the main layout cells. I created a nested table just for the video and then added an align=center attribute to the new table:

<table align=center><tr><td>
    <video width=420 height=236 controls="controls" autoplay="autoplay">
        <source src="video/video.ogv" type='video/ogg; codecs="theora, vorbis"'/>
        <source src="video/video.webm" type='video/webm' >
        <source src="video/video.mp4" type='video/mp4'>
        <p class="sidebar">If video is not visible, your browser does not support HTML5 video</p>
    </video>
</td></tr></table>

If you have a hash structure like this:

Parameters: {"link"=>{"title"=>"Something", "time_span"=>[{"start"=>"2017-05-06T16:00:00.000Z", "end"=>"2017-05-06T17:00:00.000Z"}]}}

Then this is how I got it to work:

params.require(:link).permit(:title, time_span: [[:start, :end]])

The following CSS rule disables resizing behavior for textarea elements:

textarea {
  resize: none;
}

To disable it for some (but not all) textareas, there are a couple of options.

To disable a specific textarea with the name attribute set to foo (i.e., <textarea name="foo"></textarea>):

textarea[name=foo] {
  resize: none;
}

Or, using an id attribute (i.e., <textarea id="foo"></textarea>):

#foo {
  resize: none;
}

The W3C page lists possible values for resizing restrictions: none, both, horizontal, vertical, and inherit:

textarea {
  resize: vertical; /* user can resize vertically, but width is fixed */
}

Review a decent compatibility page to see what browsers currently support this feature. As Jon Hulka has commented, the dimensions can be further restrained in CSS using max-width, max-height, min-width, and min-height.

Super important to know:

This property does nothing unless the overflow property is something other than visible, which is the default for most elements. So generally to use this, you'll have to set something like overflow: scroll;

Quote by Sara Cope, http://css-tricks.com/almanac/properties/r/resize/

Here are some ways to get total records count while doing MongoDB Aggregation:

• Using $count:

  db.collection.aggregate([
     // Other stages here
     { $count: "Total" }
  ])
  

  For getting 1000 records this takes on average 2 ms and is the fastest way.

• Using .toArray():

  db.collection.aggregate([...]).toArray().length
  

  For getting 1000 records this takes on average 18 ms.

• Using .itcount():

  db.collection.aggregate([...]).itcount()
  

  For getting 1000 records this takes on average 14 ms.

Since React uses JSX code to create an HTML we cannot refer dom using regulation methods like documment.querySelector or getElementById.

Instead we can use React ref system to access and manipulate Dom as shown in below example:

constructor(props){

    super(props);
    this.imageRef = React.createRef(); // create react ref
}

componentDidMount(){

    **console.log(this.imageRef)** // acessing the attributes of img tag when dom loads
}


render = (props) => {

const {urls,description} = this.props.image;
    return (

            <img
             **ref = {this.imageRef} // assign the ref of img tag here**
             src = {urls.regular} 
             alt = {description}
             />

        );

}

}

Yet another example for the A.B.C approach is the Eclipse Bundle Versioning. Eclipse bundles rather have a fourth segment:

In Eclipse, version numbers are composed of four (4) segments: 3 integers and a string respectively named major.minor.service.qualifier. Each segment captures a different intent:

• the major segment indicates breakage in the API
• the minor segment indicates "externally visible" changes
• the service segment indicates bug fixes and the change of development stream
• the qualifier segment indicates a particular build

you can use json_decode function

foreach (json_decode($response) as $area)
{
 print_r($area); // this is your area from json response
}

See this fiddle

Simple solution:

<?php 
exec('wget http://someurl/file.zip');

You could do something like this:

public System.Collections.IEnumerable GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                 join b in db.Breeds on d.BreedId equals b.BreedId
                 select new
                        {
                            Name = d.Name,
                            BreedName = b.BreedName
                        };
    return result.ToList();
}

I fixed it with the following steps:

• Close Visual Studio
• Run netsh http show urlacl and see if your application http address/port is listed.
• Run netsh http delete urlacl url=[ADDRESS] replacing [ADDRESS] with the Reserved URL shown by the previous command. For example http://+:17560/
• Run VS again (as Admin) then go to web project's Properties -> Web then click on Create Virtual Directory button.
• Now you should be able to run the web project.

you must have read about function call . here i give you example of it.

<?php
 funtion pr($n)
{
echo $n;
 }
?>
<form action="<?php $f=$_POST['input'];pr($f);?>" method="POST">
<input name=input type=text></input>
</form>

Try this.

.nav-tabs > li{
    float:none !important;
    display:inline-block !important;
}

.nav-tabs {
    text-align:center !important;
}

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

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

Solution was to chop that off first:

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

I have created a solution which may be of use to some people. Simply include the code on your page, and you can write your own function that will be called when the back button is clicked.

I have tested in IE, FF, Chrome, and Safari, and are all working. The solution I have works based on iframes without the need for constant polling, in IE and FF, however, due to limitations in other browsers, the location hash is used in Safari.

This will give you DD MM YYYY YY HH Min Sec variables and works on any Windows machine from XP Pro and later.

@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause

If you want to open Google Maps in a browser:

http://maps.google.com/?q=<lat>,<lng>

To open the Google Maps app on an iOS mobile device, use the Google Maps URL Scheme:

comgooglemaps://?q=<lat>,<lng>

To open the Google Maps app on Android, use the geo: intent:

geo:<lat>,<lng>?z=<zoom>

Slight adjustment to answers from ARobertson and Kenneth Wilson that worked for me.

Running R 3.6.0, with library(tidyverse) and library(dplyr) in my environment:

library(tidyverse)
library(dplyr)
> df %<>% mutate_if(is.character, as.numeric)
Error in df %<>% mutate_if(is.character, as.numeric) : 
  could not find function "%<>%"

I did some quick research and found this note in Hadley's "The tidyverse style guide".

The magrittr package provides the %<>% operator as a shortcut for modifying an object in place. Avoid this operator.

# Good x <- x %>%
           abs() %>%    
           sort()

# Bad x %<>%   
          abs() %>%
          sort()

Solution

Based on that style guide:

df_clean <- df %>% mutate_if(is.character, as.numeric)

Working example

> df_clean <- df %>% mutate_if(is.character, as.numeric)

http://jsperf.com/caching-array-length/60

The latest revision of test, which I prepared (by reusing older one), shows one thing.

Caching length is not that much important, but it does not harm.

Every first run of the test linked above (on freshly opened tab) gives best results for the last 4 snippets (3rd, 5th, 7th and 10th in charts) in Chrome, Opera and Firefox in my Debian Squeeze 64-bit (my desktop hardware). Subsequent runs give quite different result.

Performance-wise conclusions are simple:

• Go with for loop (forward) and test using !== instead of <.
• If you don't have to reuse the array later, then while loop on decremented length and destructive shift()-ing array is also efficient.

tl;dr

Nowadays (2011.10) below pattern looks to be the fastest one.

for (var i = 0, len = arr.length; i !== len; i++) {
    ...
}

Mind that caching arr.length is not crucial here, so you can just test for i !== arr.length and performance won't drop, but you'll get shorter code.

PS: I know that in snippet with shift() its result could be used instead of accessing 0th element, but I somehow overlooked that after reusing previous revision (which had wrong while loops), and later I didn't want to lose already obtained results.

To help others, I create a basic log function to handle the logging in both cases, if you want the output to stdout, then turn debug on, its straight forward to do a switch flag so you can choose your output.

func myLog(msg ...interface{}) {
    defer func() { r := recover(); if r != nil { fmt.Print("Error detected logging:", r) } }()
    if conf.DEBUG {
        fmt.Println(msg)
    } else {
        logfile, err := os.OpenFile(conf.LOGDIR+"/"+conf.AppName+".log", os.O_RDWR | os.O_CREATE | os.O_APPEND,0666)
        if !checkErr(err) {
            log.SetOutput(logfile)
            log.Println(msg)
        }
        defer logfile.Close()
    }
}

To understand this peculiar behavior of hibernate, it is important to understand a few hibernate concepts -

Hibernate Object States

Transient - An object is in transient status if it has been instantiated and is still not associated with a Hibernate session.

Persistent - A persistent instance has a representation in the database and an identifier value. It might just have been saved or loaded, however, it is by definition in the scope of a Session.

Detached - A detached instance is an object that has been persistent, but its Session has been closed.

http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/objectstate.html#objectstate-overview

Transaction Write-Behind

The next thing to understand is 'Transaction Write behind'. When objects attached to a hibernate session are modified they are not immediately propagated to the database. Hibernate does this for at least two different reasons.

• To perform batch inserts and updates.
• To propagate only the last change. If an object is updated more than once, it still fires only one update statement.

http://learningviacode.blogspot.com/2012/02/write-behind-technique-in-hibernate.html

First Level Cache

Hibernate has something called 'First Level Cache'. Whenever you pass an object to save(), update() or saveOrUpdate(), and whenever you retrieve an object using load(), get(), list(), iterate() or scroll(), that object is added to the internal cache of the Session. This is where it tracks changes to various objects.

Hibernate Intercepters and Object Lifecycle Listeners -

The Interceptor interface and listener callbacks from the session to the application, allow the application to inspect and/or manipulate properties of a persistent object before it is saved, updated, deleted or loaded. http://docs.jboss.org/hibernate/orm/4.0/hem/en-US/html/listeners.html#d0e3069

This section Updated

Cascading

Hibernate allows applications to define cascade relationships between associations. For example, 'cascade-delete' from parent to child association will result in deletion of all children when a parent is deleted.

So, why are these important.

To be able to do transaction write-behind, to be able to track multiple changes to objects (object graphs) and to be able to execute lifecycle callbacks hibernate needs to know whether the object is transient/detached and it needs to have the object in it's first level cache before it makes any changes to the underlying object and associated relationships.

That's why hibernate (sometimes) issues a 'SELECT' statement to load the object (if it's not already loaded) in to it's first level cache before it makes changes to it.

Why does hibernate issue the 'SELECT' statement only sometimes?

Hibernate issues a 'SELECT' statement to determine what state the object is in. If the select statement returns an object, the object is in detached state and if it does not return an object, the object is in transient state.

Coming to your scenario -

Delete - The 'Delete' issued a SELECT statement because hibernate needs to know if the object exists in the database or not. If the object exists in the database, hibernate considers it as detached and then re-attches it to the session and processes delete lifecycle.

Update - Since you are explicitly calling 'Update' instead of 'SaveOrUpdate', hibernate blindly assumes that the object is in detached state, re-attaches the given object to the session first level cache and processes the update lifecycle. If it turns out that the object does not exist in the database contrary to hibernate's assumption, an exception is thrown when session flushes.

SaveOrUpdate - If you call 'SaveOrUpdate', hibernate has to determine the state of the object, so it uses a SELECT statement to determine if the object is in Transient/Detached state. If the object is in transient state, it processes the 'insert' lifecycle and if the object is in detached state, it processes the 'Update' lifecycle.

I know I'm answering this question almost two and a half years after it was asked, but I just wanted to provide some hard data from a project I'm working on right now that shows that indeed doing multiple VALUE blocks per insert is MUCH faster than sequential single VALUE block INSERT statements.

The code I wrote for this benchmark in C# uses ODBC to read data into memory from an MSSQL data source (~19,000 rows, all are read before any writing commences), and the MySql .NET connector (Mysql.Data.*) stuff to INSERT the data from memory into a table on a MySQL server via prepared statements. It was written in such a way as to allow me to dynamically adjust the number of VALUE blocks per prepared INSERT (ie, insert n rows at a time, where I could adjust the value of n before a run.) I also ran the test multiple times for each n.

Doing single VALUE blocks (eg, 1 row at a time) took 5.7 - 5.9 seconds to run. The other values are as follows:

2 rows at a time: 3.5 - 3.5 seconds
5 rows at a time: 2.2 - 2.2 seconds
10 rows at a time: 1.7 - 1.7 seconds
50 rows at a time: 1.17 - 1.18 seconds
100 rows at a time: 1.1 - 1.4 seconds
500 rows at a time: 1.1 - 1.2 seconds
1000 rows at a time: 1.17 - 1.17 seconds

So yes, even just bundling 2 or 3 writes together provides a dramatic improvement in speed (runtime cut by a factor of n), until you get to somewhere between n = 5 and n = 10, at which point the improvement drops off markedly, and somewhere in the n = 10 to n = 50 range the improvement becomes negligible.

Hope that helps people decide on (a) whether to use the multiprepare idea, and (b) how many VALUE blocks to create per statement (assuming you want to work with data that may be large enough to push the query past the max query size for MySQL, which I believe is 16MB by default in a lot of places, possibly larger or smaller depending on the value of max_allowed_packet set on the server.)

If you want to know the row and column of a value in a matrix or data.frame, consider using the arr.ind=TRUE argument to which:

> which(mydata_2 == 1578, arr.ind=TRUE)
  row col
7   7   3

So 1578 is in column 3 (which you already know) and row 7.

I came across the same issue. My service is uploading/receiving XMLS and write the errors to the Event Log.

When I went to the Event Log, I tried to filter it. It prompt me that the Event Log was corrupted.

I cleared the Event Log and all OK.

Try this:

1. Download and install a 32-bit JDK.
2. Go to eclipse click on your project (Run As ? Run Configurations...) under Java Application branch.
3. Go to the JRE tab and select Alternate JRE. Click on Installed JRE button, add your 32-bit JRE and select.

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

It depends on which Ruby version you use:

Ruby 2.4 and higher:

It just works, as since Ruby v2.4.0 supports Unicode case mapping:

"?????".capitalize #=> ?????

Ruby 2.3 and lower:

"maria".capitalize #=> "Maria"
"?????".capitalize #=> ?????

The problem is, it just doesn't do what you want it to, it outputs ????? instead of ?????.

If you're using Rails there's an easy workaround:

"?????".mb_chars.capitalize.to_s # requires ActiveSupport::Multibyte

Otherwise, you'll have to install the unicode gem and use it like this:

require 'unicode'

Unicode::capitalize("?????") #=> ?????

Ruby 1.8:

Be sure to use the coding magic comment:

#!/usr/bin/env ruby

puts "?????".capitalize

gives invalid multibyte char (US-ASCII), while:

#!/usr/bin/env ruby
#coding: utf-8

puts "?????".capitalize

works without errors, but also see the "Ruby 2.3 and lower" section for real capitalization.

String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> namesList = Arrays.asList(names);

or

String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> temp = Arrays.asList(names);         

Above Statement adds the wrapper on the input array. So the methods like add & remove will not be applicable on list reference object 'namesList'.

If you try to add an element in the existing array/list then you will get "Exception in thread "main" java.lang.UnsupportedOperationException".

The above operation is readonly or viewonly.
We can not perform add or remove operation in list object. But

String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.ArrayList<String> list1 = new ArrayList<>(Arrays.asList(names));

or

String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> listObject = Arrays.asList(names);
java.util.ArrayList<String> list1 = new ArrayList<>(listObject);

In above statement you have created a concrete instance of an ArrayList class and passed a list as a parameter.

In this case method add & remove will work properly as both methods are from ArrayList class so here we won't get any UnSupportedOperationException.
Changes made in Arraylist object (method add or remove an element in/from an arraylist) will get not reflect in to original java.util.List object.

String names[] = new String[] {
    "Avinash",
    "Amol",
    "John",
    "Peter"
};

java.util.List < String > listObject = Arrays.asList(names);
java.util.ArrayList < String > list1 = new ArrayList < > (listObject);
for (String string: list1) {
    System.out.print("   " + string);
}
list1.add("Alex"); //Added without any exception
list1.remove("Avinash"); //Added without any exception will not make any changes in original list in this case temp object.


for (String string: list1) {
    System.out.print("   " + string);
}
String existingNames[] = new String[] {
    "Avinash",
    "Amol",
    "John",
    "Peter"
};
java.util.List < String > namesList = Arrays.asList(names);
namesList.add("Bob"); // UnsupportedOperationException occur
namesList.remove("Avinash"); //UnsupportedOperationException

This is difficult with worksheet functions because dates in excel are simply formatted numbers - only CELL function lets you investigate the format of a cell (and you can't apply that to a range, so a helper column would be required).......or, if you only have dates and blanks.....or dates and text then it would be sufficient to use COUNT function, i.e.

=COUNT(range)

That counts numbers so it won't be adequate if you want to distinguish dates from numbers. If you do then the number range could be utilised, e.g. if you have numbers in a range and dates but the numbers will all be lower than 10,000 and the dates will all be relatively recent then you could use this version to exclude the numbers

=COUNTIF(range,">10000")

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

I have been struggling with how to add query string parameters to my URL. I couldn't make it work until I realized that I needed to add ? at the end of my URL, otherwise it won't work. This is very important as it will save you hours of debugging, believe me: been there...done that.

Below, is a simple API Endpoint that calls the Open Weather API and passes APPID, lat and lon as query parameters and return weather data as a JSON object. Hope this helps.

//Load the request module
var request = require('request');

//Load the query String module
var querystring = require('querystring');

// Load OpenWeather Credentials
var OpenWeatherAppId = require('../config/third-party').openWeather;

router.post('/getCurrentWeather', function (req, res) {
    var urlOpenWeatherCurrent = 'http://api.openweathermap.org/data/2.5/weather?'
    var queryObject = {
        APPID: OpenWeatherAppId.appId,
        lat: req.body.lat,
        lon: req.body.lon
    }
    console.log(queryObject)
    request({
        url:urlOpenWeatherCurrent,
        qs: queryObject
    }, function (error, response, body) {
        if (error) {
            console.log('error:', error); // Print the error if one occurred

        } else if(response && body) {
            console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
            res.json({'body': body}); // Print JSON response.
        }
    })
})  

Or if you want to use the querystring module, make the following changes

var queryObject = querystring.stringify({
    APPID: OpenWeatherAppId.appId,
    lat: req.body.lat,
    lon: req.body.lon
});

request({
   url:urlOpenWeatherCurrent + queryObject
}, function (error, response, body) {...})

I prefer feature before layers, but I guess it depends on you project. Consider your forces:

• Dependencies
  Try minimize package dependencies, especially between features. Extract APIs if necessary.
• Team organization
  In some organizations teams work on features and in others on layers. This influence how code is organized, use it to formalize APIs or encourage cooperation.
• Deployment and versioning
  Putting everything into a module make deployment and versioning simpler, but bug fixing harder. Splitting things enable better control, scalability and availability.
• Respond to change
  Well organized code is much simpler to change than a big ball of mud.
• Size (people and lines of code)
  The bigger the more formalized/standardized it needs to be.
• Importance/quality
  Some code is more important than other. APIs should be more stable then the implementation. Therefore it needs to be clearly separated.
• Level of abstraction and entry point
  It should be possible for an outsider to know what the code is about, and where to start reading from looking at the package tree.

Example:

com/company/module
  + feature1/
    - MainClass          // The entry point for exploring
    + api/               // Public interface, used by other features
    + domain/
      - AggregateRoot
      + api/             // Internal API, complements the public, used by web
      + impl/ 
    + persistence/       
    + web/               // presentation layer 
    + services/          // Rest or other remote API 
    + support/            
  + feature2/
  + support/             // Any support or utils used by more than on feature
    + io
    + config
    + persistence
    + web

This is just an example. It is quite formal. For example it defines 2 interfaces for feature1. Normally that is not required, but could be a good idea if used differently by different people. You may let the internal API extend the public.

I do not like the 'impl' or 'support' names, but they help separate the less important stuff from the important (domain and API). When it comes to naming I like to be as concrete as possible. If you have a package called 'utils' with 20 classes, move StringUtils to support/string, HttpUtil to support/http and so on.

I love code examples (as well as fruit), so let me show you

apple = "apple"
print(apple)
>>> apple
apple = None
print(apple)
>>> None

None means nothing, it has no value.

None evaluates to False.

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

Try this:

<td bgcolor="#FFFFFF" style="line-height:10px;" colspan=3>&nbsp;</td>

It's a link that links to nowhere essentially (it just adds "#" onto the URL). It's used for a number of different reasons. For instance, if you're using some sort of JavaScript/jQuery and don't want the actual HTML to link anywhere.

It's also used for page anchors, which is used to redirect to a different part of the page.

The answers so far tell you how to find existing branches:

git branch -r

Or repositories for the same project [see note below]:

git remote -v

There is another case. You might want to know about other project repositories hosted on the same server.

To discover that information, I use SSH or PuTTY to log into to host and ls to find the directories containing the other repositories. For example, if I cloned a repository by typing:

git clone ssh://git.mycompany.com/git/ABCProject

and want to know what else is available, I log into git.mycompany.com via SSH or PuTTY and type:

ls /git

assuming ls says:

 ABCProject DEFProject

I can use the command

 git clone ssh://git.mycompany.com/git/DEFProject

to gain access to the other project.

NOTE: Usually git remote simply tells me about origin -- the repository from which I cloned the project. git remote would be handy if you were collaborating with two or more people working on the same project and accessing each other's repositories directly rather than passing everything through origin.

I think you're confusing the text and HTML methods. Look at this example, if you use an element's inner HTML as text, you'll get decoded HTML tags (second button). But if you use them as HTML, you'll get the HTML formatted view (first button).

<div id="myDiv">
    here is a <b>HTML</b> content.
</div>
<br />
<input value="Write as HTML" type="button" onclick="javascript:$('#resultDiv').html($('#myDiv').html());" />
&nbsp;&nbsp;
<input value="Write as Text" type="button" onclick="javascript:$('#resultDiv').text($('#myDiv').html());" />
<br /><br />
<div id="resultDiv">
    Results here !
</div>

First button writes : here is a HTML content.

Second button writes : here is a <B>HTML</B> content.

By the way, you can see a plug-in that I found in jQuery plugin - HTML decode and encode that encodes and decodes HTML strings.

I can't set "UTF-8 with BOM" in the corner button either, but I can change it from the menu bar.

"File"->"Save with encoding"->"UTF-8 with BOM"

You cannot put primitive types into collections. However, you can declare them using their corresponding object wrappers and still add the primitive values, as long as the boxing allows you.

The show() method only affects the display CSS setting. If you want to set the visibility you need to do it directly. Also, the .load_button element is a button and does not raise a submit event. You would need to change your selector to the form for that to work:

$('#login_form').submit(function() {
    $('#gif').css('visibility', 'visible');
});

Also note that return true; is redundant in your logic, so it can be removed.

I like the build-in pathlib libary because of quick options like directory= Path.cwd() Together with opencv it's quite easy to read pngs to numpy arrays. In this example you can even check the prefix of the image.

from pathlib import Path
import cv2
prefix = "p00"
suffix = ".png"
directory= Path.cwd()
file_names= [subp.name for subp in directory.rglob('*') if  (prefix in subp.name) & (suffix == subp.suffix)]
file_names.sort()
print(file_names)

all_frames= []
for file_name in file_names:
    file_path = str(directory / file_name)
    frame=cv2.imread(file_path)
    all_frames.append(frame)
print(type(all_frames[0]))
print(all_frames[0] [1][1])

Output:

['p000.png', 'p001.png', 'p002.png', 'p003.png', 'p004.png', 'p005.png', 'p006.png', 'p007.png', 'p008.png', 'p009.png']
<class 'numpy.ndarray'>

When we click on an "input" element, it gets "focused" on. Removing the blue highlighter for this "focus" action is as simple as below. To give it gray color, you could define a gray border.

select:focus{
    border-color: gray;
    outline:none;
}

if you're turned off by the extra line, you can use a wrapper function like so:

def with_iter(iterable):
    with iterable as iter:
        for item in iter:
            yield item

for line in with_iter(open('...')):
    ...

in Python 3.3, the yield from statement would make this even shorter:

def with_iter(iterable):
    with iterable as iter:
        yield from iter

I've been having this problem too and I'm not sure why. Some people suggest removing your Google account and re-adding it and/or deleting the Play Store cache. I'm looking for more solutions, but it happens for all apps free, paid, whatever.

EDIT: just found this http://www.droid-life.com/2012/11/14/after-4-2-update-is-your-nexus-7-having-troubles-updating-apps-in-google-play/

It would be just as convenient to simply convert your collection into a list whenever it updates. But if you are initializing, this will suffice:

for(String i : collectionlist){
    arraylist.add(i);
    whateverIntID = arraylist.indexOf(i);
}

Be open-minded.

If you don't mind the binary size, you can use iproute2 as library.

iproute2-as-lib

Pros:

• No need to write the socket layer code.
• More or even more information about network interfaces can be got. Same functionality with the iproute2 tools.
• Simple API interface.

Cons:

• iproute2-as-lib library size is big. ~500kb.

This fixed node.js not running on port 80 under Windows 10 as well, I was getting a listen eacces error. Start > Services, find "World Wide Web Publish Service" and disable it, exactly as paaacman described.

The attributes src and data-src have nothing in common, except that they are both allowed by HTML5 CR and they both contain the letters src. Everything else is different.

The src attribute is defined in HTML specs, and it has a functional meaning.

The data-src attribute is just one of the infinite set of data-* attributes, which have no defined meaning but can be used to include invisible data in an element, for use in scripting (or styling).

Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):

https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf

https://github.com/medo64/render-crlf/

It can be configured like this:

{
    "editor.renderWhitespace": "all",
    "code-eol.newlineCharacter": "¬",
    "code-eol.returnCharacter" : "¤",
    "code-eol.crlfCharacter"   : "¤¬",
}

and looks like this:

This one-liner works for me:

WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials;

CredentialCache.DefaultNetWorkCredentials is the proxy settings set in Internet Explorer.

WebRequest.DefaultWebProxy.Credentials is used for all internet connectivity in the application.

Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.

That's why you can't use something 'not hashable' as a dict key, like a list:

>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable

You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

This works well for me. It uses an array so you aren't looping through each cell. Runs much faster over large worksheet sections.

Sub Trim_Cells_Array_Method()

Dim arrData() As Variant
Dim arrReturnData() As Variant
Dim rng As Excel.Range
Dim lRows As Long
Dim lCols As Long
Dim i As Long, j As Long

  lRows = Selection.Rows.count
  lCols = Selection.Columns.count

  ReDim arrData(1 To lRows, 1 To lCols)
  ReDim arrReturnData(1 To lRows, 1 To lCols)

  Set rng = Selection
  arrData = rng.value

  For j = 1 To lCols
    For i = 1 To lRows
      arrReturnData(i, j) = Trim(arrData(i, j))
    Next i
  Next j

  rng.value = arrReturnData

  Set rng = Nothing
End Sub

If you want to extract the hours, minutes and seconds, try this:

String inputDate = "12:00:00";
String[] split = inputDate.split(":");
int hours = Integer.valueOf(split[0]);
int minutes = Integer.valueOf(split[1]);
int seconds = Integer.valueOf(split[2]);

One reason I love Python is that it is much better standardized than the POSIX tools. I have to double and triple check that each bit is compatible with other operating systems. A program written on a Linux system might not work the same on a BSD system of OSX. With Python, I just have to check that the target system has a sufficiently modern version of Python.

Even better, a program written in standard Python will even run on Windows!

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.feature_wrapper span {
    float: left;
    clear: left;
    display:inline
}

EDIT: now browsers have better support you can make use of the do inline-block.

.feature_wrapper span {
    display:inline-block;
    *display:inline; *zoom:1;
}

Depending on the text-align this will appear as through its inline while also acting like a block element.

Put [] around any field names that had spaces (as Dreden says) and save your query, close it and reopen it.

Using Access 2016, I still had the error message on new queries after I added [] around any field names... until the Query was saved.

Once the Query is saved (and visible in the Objects' List), closed and reopened, the error message disappears. This seems to be a bug from Access.

Give my credit to @chad-m 's answer.

Here is the Swift version:

1. Create a new file MyNavigationController.swift

import UIKit

class MyNavigationController: UINavigationController, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        self.delegate = self
    }

    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        if viewController == self.viewControllers.first {
            self.setNavigationBarHidden(true, animated: animated)
        } else {
            self.setNavigationBarHidden(false, animated: animated)
        }
    }

}

2. Set your UINavigationController's class in StoryBoard to MyNavigationController That's it!

Difference between chad-m's answer and mine:

1. Inherit from UINavigationController, so you won't pollute your rootViewController.

2. use self.viewControllers.first rather than homeViewController, so you won't do this 100 times for your 100 UINavigationControllers in 1 StoryBoard.

LIKE is used for pattern matching and = is used for equality test (as defined by the COLLATION in use).

= can use indexes while LIKE queries usually require testing every single record in the result set to filter it out (unless you are using full text search) so = has better performance.

Here is the code you can use for every browser:

Here is a comparison of the 3 ways you can watch a scope variable with examples:

$watch() is triggered by:

$scope.myArray = [];
$scope.myArray = null;
$scope.myArray = someOtherArray;

$watchCollection() is triggered by everything above AND:

$scope.myArray.push({}); // add element
$scope.myArray.splice(0, 1); // remove element
$scope.myArray[0] = {}; // assign index to different value

$watch(..., true) is triggered by EVERYTHING above AND:

$scope.myArray[0].someProperty = "someValue";

JUST ONE MORE THING...

$watch() is the only one that triggers when an array is replaced with another array even if that other array has the same exact content.

For example where $watch() would fire and $watchCollection() would not:

$scope.myArray = ["Apples", "Bananas", "Orange" ];

var newArray = [];
newArray.push("Apples");
newArray.push("Bananas");
newArray.push("Orange");

$scope.myArray = newArray;

Below is a link to an example JSFiddle that uses all the different watch combinations and outputs log messages to indicate which "watches" were triggered:

http://jsfiddle.net/luisperezphd/2zj9k872/

Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:

JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);

According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:

 Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
 return font.deriveFont(12f);

SELECT *
  FROM Customer
 WHERE (I.IsClose=@ISClose OR @ISClose is NULL)  
   AND (C.FirstName like '%'+@ClientName+'%' or @ClientName is NULL )    
   AND (isnull(@Value,1) <> 2
        OR I.RecurringCharge = @Total
        OR @Total is NULL )    
   AND (isnull(@Value,2) <> 3
        OR I.RecurringCharge like '%'+cast(@Total as varchar(50))+'%'
        OR @Total is NULL )

Basically, your condition was

if (@Value=2)
   TEST FOR => (I.RecurringCharge=@Total  or @Total is NULL )    

flipped around,

AND (isnull(@Value,1) <> 2                -- A
        OR I.RecurringCharge = @Total    -- B
        OR @Total is NULL )              -- C

When (A) is true, i.e. @Value is not 2, [A or B or C] will become TRUE regardless of B and C results. B and C are in reality only checked when @Value = 2, which is the original intention.

Try this...

<div class="row">
    <div class="col-xs-3">
        Menu
    </div>
    <div class="col-xs-9">
        <div class="row">
          <div class="col-sm-4 col-sm-push-8">
          Right content
          </div>
          <div class="col-sm-8 col-sm-pull-4">
          Content
          </div>
       </div>
    </div>

Try this method to get path of original image captured by camera.

public String getOriginalImagePath() {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = getActivity().managedQuery(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                projection, null, null, null);
        int column_index_data = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToLast();

        return cursor.getString(column_index_data);
    }

This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.

Some times eclipse may confuse with other projects in the same directory.

Just change package name (don't forget to change in Android manifest file also), ensure the package name is not used already in the directory. It may work.

In C++11 you can:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  std::make_tuple(dividend / divisor, dividend % divisor);
}

#include <iostream>

int main() {
    using namespace std;

    int quotient, remainder;

    tie(quotient, remainder) = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

In C++17:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

or with structs:

auto divide(int dividend, int divisor) {
    struct result {int quotient; int remainder;};
    return result {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto result = divide(14, 3);

    cout << result.quotient << ',' << result.remainder << endl;

    // or

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

I personally use a more generic function that works for any property of any array:

function lookup(array, prop, value) {
    for (var i = 0, len = array.length; i < len; i++)
        if (array[i] && array[i][prop] === value) return array[i];
}

You just call it like this:

lookup(purposeObjects, "purpose", "daily");

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

Here's another good one: http://www.saltycrane.com/blog/2009/05/notes-using-pip-and-virtualenv-django/

This one shows how to use pip and a pip requirements file with virtualenv; Scobal's two suggested tutorials are both very helpful but are both easy_install-centric.

Note that none of these tutorials explain how to run a different version of Python within a virtualenv - for this, see this SO question: Use different Python version with virtualenv

The 'sed' solutions mentioned earlier are nice but as mentioned not 100% secure

• You may have INSERT commands with data containing: ... CREATE TABLE...(whatever)...mytable...

• or even the exact string "CREATE TABLE `mytable`;" if you are storing DML commands for instance!

(and if the table is huge you don't want to check that manually)

I would verify the exact syntax of the dump version used, and have a more restrictive pattern search:

Avoid ".*" and use "^" to ensure we start at the begining of the line. And I'd prefer to grab the initial 'DROP'

All in all, this works better for me:

sed -n -e '/^DROP TABLE IF EXISTS \`mytable\`;/,/^UNLOCK TABLES;/p' mysql.dump > mytable.dump

MySQL Workbench

If you want to avoid writing sql, you can also do it in MySQL Workbench by right clicking on the table, choose "Alter Table ..." in the menu.

When the table structure view opens, go to tab "Options" (on the lower bottom of the view), and set "Auto Increment" field to the value of the next autoincrement number.

Don't forget to hit "Apply" when you are done with all changes.

PhpMyAdmin:

If you are using phpMyAdmin, you can click on the table in the lefthand navigation, go to the tab "Operations" and under Table Options change the AUTO_INCREMENT value and click OK.

In addition to probably throwing something derived from std::exception you should throw anonymous temporaries and catch by reference:

void Foo::Bar(){
  if(!QueryPerformanceTimer(&m_baz)){
    throw std::string("it's the end of the world!");
  }
}

void Foo:Caller(){
  try{
    this->Bar();// should throw
  }catch(std::string& caught){ // not quite sure the syntax is ok here...
    std::cout<<"Got "<<caught<<std::endl;
  }
}

• You should throw anonymous temporaries so the compiler deals with the object lifetime of whatever you're throwing - if you throw something new-ed off the heap, someone else needs to free the thing.
• You should catch references to prevent object slicing

.

See Meyer's "Effective C++ - 3rd edition" for details or visit https://www.securecoding.cert.org/.../ERR02-A.+Throw+anonymous+temporaries+and+catch+by+reference

It's better something like this...post the data to the self page and maybe do a check on user input.

   <?php
    require_once ( 'username.php' );

    if(isset($_POST)) {
      echo "form post"; // ex $_POST['textfield']
    }


    echo '
    <form name="form1" method="post" action="' . $_SERVER['PHP_SELF'] . '">
      <p>
        <label>
          <input type="text" name="textfield" id="textfield">
        </label>
      </p>
      <p>
        <label>
          <input type="submit" name="button" id="button" value="Submit">
        </label>
      </p>
    </form>';
    ?>

Another situation which issues the same problem, map.entrySet().iterator().next()

If there is no element in the Map object, then the above code will return NoSuchElementException. Make sure to call hasNext() first.

The better and dynamic solution I have found is to use $watch to trace the variable changes and then update the title.

I tested and the script run ok!

INSERT INTO HISTORICAL_CAR_STATS (HISTORICAL_CAR_STATS_ID, YEAR,MONTH,MAKE,MODEL,REGION,AVG_MSRP,COUNT) 
WITH DATA AS

    SELECT '2010' YEAR,'12' MONTH ,'ALL' MAKE,'ALL' MODEL,REGION,sum(AVG_MSRP*COUNT)/sum(COUNT) AVG_MSRP,sum(Count) COUNT
    FROM HISTORICAL_CAR_STATS
    WHERE YEAR = '2010' AND MONTH = '12'
    AND MAKE != 'ALL' GROUP BY REGION
)
SELECT MY_SEQ.NEXTVAL, YEAR,MONTH,MAKE,MODEL,REGION,AVG_MSRP,COUNT
FROM DATA;

the command posted by Milad and Sandy did not work for me with mstsc. i had to add TERMSRV to the /generic switch. i found this information here: https://gist.github.com/jdforsythe/48a022ee22c8ec912b7e

cmdkey /generic:TERMSRV/<server> /user:<username> /pass:<password>

i could then use mstsc /v:<server> without getting prompted for the login.

Ladislav's answer updated to use DbContext (introduced in EF 4.1):

public void ChangePassword(int userId, string password)
{
    var user = new User() { Id = userId, Password = password };
    using (var db = new MyEfContextName())
    {
        db.Users.Attach(user);
        db.Entry(user).Property(x => x.Password).IsModified = true;
        db.SaveChanges();
    }
}

You need a regular expression for this. Look here. If you are using .net Framework4.5 then you can also use this. As it is built in .net Framework 4.5. Example

[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }

There's the -W option.

python -W ignore foo.py

There is a new discussion about this (https://github.com/angular/angular/issues/4933). So far there is only some hacks that allows to clear the form, like recreating the whole form after submitting: https://embed.plnkr.co/kMPjjJ1TWuYGVNlnQXrU/

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Jsf 2.0

try this code...

<RelativeLayout 
         xmlns:android="http://schemas.android.com/apk/res/android" 
         android:layout_width="fill_parent" 
         android:layout_height="fill_parent" 
         android:background="#ffff00"> 

    <ListView 
            android:id="@+id/android:list" 
            android:layout_marginTop="2px" 
            android:layout_marginLeft="2px" 
            android:layout_marginRight="2px"
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:layout_weight="1" 
            android:background="@drawable/shape_1" 
            android:listSelector="@drawable/shape_3" 
            android:textColor="#ffff00" 
            android:layout_marginBottom="44px" /> 
</RelativeLayout>

Please note, buttons and other elements in API 21 and greater have a high elevation, and therefore ignore the xml order of elements regardless of parent layout. Took me a while to figure that one out.

The mutating method of StringProtocol replacingOccurrences can be implemented as follow:

extension RangeReplaceableCollection where Self: StringProtocol {
    mutating func replaceOccurrences<Target: StringProtocol, Replacement: StringProtocol>(of target: Target, with replacement: Replacement, options: String.CompareOptions = [], range searchRange: Range<String.Index>? = nil) {
        self = .init(replacingOccurrences(of: target, with: replacement, options: options, range: searchRange))
    }
}

var name = "This is my string"
name.replaceOccurrences(of: " ", with: "+")
print(name) // "This+is+my+string\n"

Create procedure [dbo].[a]

@examdate varchar(10) ,
@examdate1 varchar(10)
AS
Select tbl.sno,mark,subject1,
Convert(varchar(10),examdate,103) from tbl
where 
(Convert(datetime,examdate,103)  >= Convert(datetime,@examdate,103) 
and (Convert(datetime,examdate,103) <=  Convert(datetime,@examdate1,103)))

{% if variable is defined %} works to check if something is undefined.

You can get away with using {% if not var1 %} if you default your variables to False eg

class MainHandler(BaseHandler):
    def get(self):
        var1 = self.request.get('var1', False)

Try using float: left (or right) instead of display: inline. Inline display replaces list-item display, which is what adds the bullet points.

You can use awk, sort & uniq to do this, for example to list all the unique values in the first column

awk < test.txt '{print $1}' | sort | uniq

As posted elsewhere, if you want to count the number of instances of something you can pipe the unique list into wc -l

It is useful to think of MIME in the context of the client-server model. Clients and servers communicate over what is known as the HTTP protocol. In a http request or response, we can have a body. The Content-type or MIME type specifies what is the type of the body, like text/javascript or something else like audio, video, etc.

However, MIME types are not limited just to HTTP.

As the name suggests, MIME stands for Multipurpose Internet Mail Extensions. Originally, SMTP only supported ascii-encodings. However, there as a need for more. We could use MIME to slap a label on the content being transmitted or received.

This somewhat helps:

How many thousands of users?

I've run some TCP/IP client/server connection tests in the past on Windows 2003 Server and managed more than 70,000 connections on a reasonably low spec VM. (see here for details: http://www.lenholgate.com/blog/2005/10/the-64000-connection-question.html). I would be extremely surprised if Windows 2008 Server is limited to less than 2003 Server and, IMHO, the posting that Cloud links to is too vague to be much use. This kind of question comes up a lot, I blogged about why I don't really think that it's something that you should actually worry about here: http://www.serverframework.com/asynchronousevents/2010/12/one-million-tcp-connections.html.

Personally I'd test it and see. Even if there is no inherent limit in the Windows 2008 Server version that you intend to use there will still be practical limits based on memory, processor speed and server design.

If you want to run some 'generic' tests you can use my multi-client connection test and the associated echo server. Detailed here: http://www.lenholgate.com/blog/2005/11/windows-tcpip-server-performance.html and here: http://www.lenholgate.com/blog/2005/11/simple-echo-servers.html. These are what I used to run my own tests for my server framework and these are what allowed me to create 70,000 active connections on a Windows 2003 Server VM with 760MB of memory.

Edited to add details from the comment below...

If you're already thinking of multiple servers I'd take the following approach.

1. Use the free tools that I link to and prove to yourself that you can create a reasonable number of connections onto your target OS (beware of the Windows limits on dynamic ports which may cause your client connections to fail, search for MAX_USER_PORT).

2. during development regularly test your actual server with test clients that can create connections and actually 'do something' on the server. This will help to prevent you building the server in ways that restrict its scalability. See here: http://www.serverframework.com/asynchronousevents/2010/10/how-to-support-10000-or-more-concurrent-tcp-connections-part-2-perf-tests-from-day-0.html

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

If you use R Studio http://rstudio.org/ there is a special menu to save you plot as any format you like and at any resolution you choose

Basically there's three things you can do

1. Ensure that your user account has administrator privilege.
2. Disable User Account Control (UAC).
3. Install in C://xampp.

I've just writen an answer to a very similar answer here where I explain how you can disable UAC since Windows 8.

Direct access

If you use ID then you have direct access to input in JS global scope

myInput.value = 'default_value'

<input id="myInput">

#include <iostream>
#include <string>
#include <sstream>
int main(){
    std::string myText("some-text-to-tokenize");
    std::istringstream iss(myText);
    std::string token;
    while (std::getline(iss, token, '-'))
    {
        std::cout << token << std::endl;
    }
    return 0;
}

Or, as mentioned, use boost for more flexibility.

Try a case statement

WHERE
CASE WHEN @zipCode IS NULL THEN 1
ELSE @zipCode
END

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

I am copy pasting from the Jupyter/IPython Notebook Quick Start Guide Documentation, released on Feb 13, 2018. http://jupyter-notebook-beginner-guide.readthedocs.io/en/latest/execute.html

1.3.3 Close a notebook: kernel shut down When a notebook is opened, its “computational engine” (called the kernel) is automatically started. Closing the notebook browser tab, will not shut down the kernel, instead the kernel will keep running until is explicitly shut down. To shut down a kernel, go to the associated notebook and click on menu File -> Close and Halt. Alternatively, the Notebook Dashboard has a tab named Running that shows all the running notebooks (i.e. kernels) and allows shutting them down (by clicking on a Shutdown button).

Summary: First close and halt the notebooks running.

1.3.2 Shut down the Jupyter Notebook App Closing the browser (or the tab) will not close the Jupyter Notebook App. To completely shut it down you need to close the associated terminal. In more detail, the Jupyter Notebook App is a server that appears in your browser at a default address (http://localhost:8888). Closing the browser will not shut down the server. You can reopen the previous address and the Jupyter Notebook App will be redisplayed. You can run many copies of the Jupyter Notebook App and they will show up at a similar address (only the number after “:”, which is the port, will increment for each new copy). Since with a single Jupyter Notebook App you can already open many notebooks, we do not recommend running multiple copies of Jupyter Notebook App.

Summary: Second, quit the terminal from which you fired Jupyter.

On each loop of the result set, you're appending a new root element to the document, creating an XML document like this:

<?xml version="1.0"?>
<mycatch>...</mycatch>
<mycatch>...</mycatch>
...

An XML document can only have one root element, which is why the error is stating there is "extra content". Create a single root element and add all the mycatch elements to that:

$root = $dom->createElement("root");
$dom->appendChild($root);
// ...
while ($row = @mysql_fetch_assoc($result)){
  $node = $dom->createElement("mycatch");
  $root->appendChild($node);

Below are scripts for emptying and deleting a Kafka topic assuming localhost as the zookeeper server and Kafka_Home is set to the install directory:

The script below will empty a topic by setting its retention time to 1 second and then removing the configuration:

#!/bin/bash
echo "Enter name of topic to empty:"
read topicName
/$Kafka_Home/bin/kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name $topicName --add-config retention.ms=1000
sleep 5
/$Kafka_Home/bin/kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name $topicName --delete-config retention.ms

To fully delete topics you must stop any applicable kafka broker(s) and remove it's directory(s) from the kafka log dir (default: /tmp/kafka-logs) and then run this script to remove the topic from zookeeper. To verify it's been deleted from zookeeper the output of ls /brokers/topics should no longer include the topic:

#!/bin/bash
echo "Enter name of topic to delete from zookeeper:"
read topicName
/$Kafka_Home/bin/zookeeper-shell localhost:2181 <<EOF
rmr /brokers/topics/$topicName
ls /brokers/topics
quit
EOF

You want to use the live() function. See the docs.

For example:

$("#anchor1").live("click", function() {
    $("#anchor1").append('<a class="myclass" href="#">test4</a>');
});

mapStateToProps() is a utility which helps your component get updated state(which is updated by some other components),
mapDispatchToProps() is a utility which will help your component to fire an action event (dispatching action which may cause change of application state)

Just after your Page_Load add this:

public override void VerifyRenderingInServerForm(Control control)
{
    //base.VerifyRenderingInServerForm(control);
}

Note that I don't do anything in the function.

EDIT: Tim answered the same thing. :) You can also find the answer Here

str.matches(regex) behaves like Pattern.matches(regex, str) which attempts to match the entire input sequence against the pattern and returns

true if, and only if, the entire input sequence matches this matcher's pattern

Whereas matcher.find() attempts to find the next subsequence of the input sequence that matches the pattern and returns

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

Thus the problem is with the regex. Try the following.

String test = "User Comments: This is \t a\ta \ntest\n\n message \n";

String pattern1 = "User Comments: [\\s\\S]*^test$[\\s\\S]*";
Pattern p = Pattern.compile(pattern1, Pattern.MULTILINE);
System.out.println(p.matcher(test).find());  //true

String pattern2 = "(?m)User Comments: [\\s\\S]*^test$[\\s\\S]*";
System.out.println(test.matches(pattern2));  //true

Thus in short, the (\\W)*(\\S)* portion in your first regex matches an empty string as * means zero or more occurrences and the real matched string is User Comments: and not the whole string as you'd expect. The second one fails as it tries to match the whole string but it can't as \\W matches a non word character, ie [^a-zA-Z0-9_] and the first character is T, a word character.

Use putty. Put install directory path in environment values (PATH), and restart your PC if required.

Open cmd (command prompt) and type

C:/> pscp "C:\Users/gsjha/Desktop/example.txt" user@host:/home/

It'll be copied to the system.

These commands worked for me:

npm uninstall -g cordova
npm uninstall -g ionic

Using text/csv is the most appropriate type.

You should also consider adding a Content-Disposition header to the response. Often a text/csv will be loaded by a Internet Explorer directly into a hosted instance of Excel. This may or may not be a desirable result.

Response.AddHeader("Content-Disposition", "attachment;filename=myfilename.csv");

The above will cause a file "Save as" dialog to appear which may be what you intend.

copied from: https://android.stackexchange.com/questions/12962/flush-clear-dns-cache

Addresses are cached for 600 seconds (10 minutes) by default. Failed lookups are cached for 10 seconds. From everything I've seen, there's nothing built in to flush the cache. This is apparently a reported bug http://code.google.com/p/android/issues/detail?id=7904 in Android because of the way it stores DNS cache. Clearing the browser cache doesn't touch the DNS, the "hard reset" clears it.

Another use of BST over Heap; because of an important difference :

• finding successor and predecessor in a BST will take O(h) time. ( O(logn) in balanced BST)
• while in Heap, would take O(n) time to find successor or predecessor of some element.

Use of BST over a Heap: Now, Lets say we use a data structure to store landing time of flights. We cannot schedule a flight to land if difference in landing times is less than 'd'. And assume many flights have been scheduled to land in a data structure(BST or Heap).

Now, we want to schedule another Flight which will land at t. Hence, we need to calculate difference of t with its successor and predecessor (should be >d). Thus, we will need a BST for this, which does it fast i.e. in O(logn) if balanced.

EDITed:

Sorting BST takes O(n) time to print elements in sorted order (Inorder traversal), while Heap can do it in O(n logn) time. Heap extracts min element and re-heapifies the array, which makes it do the sorting in O(n logn) time.

In your current code, you save the GState of the current context, configure it to draw a shadow .. and the restore it to what it was before you configured it to draw a shadow. Then, finally, you invoke the superclass's implementation of drawRect: .

Any drawing that should be affected by the shadow setting needs to happen after

CGContextSetShadow(currentContext, CGSizeMake(-15, 20), 5);

but before

CGContextRestoreGState(currentContext);

So if you want the superclass's drawRect: to be 'wrapped' in a shadow, then how about if you rearrange your code like this?

- (void)drawRect:(CGRect)rect {
    CGContextRef currentContext = UIGraphicsGetCurrentContext();
    CGContextSaveGState(currentContext);
    CGContextSetShadow(currentContext, CGSizeMake(-15, 20), 5);
    [super drawRect: rect];
    CGContextRestoreGState(currentContext);
}

You can try using AppDomain.UnhandledException and see if that lets you catch it.

**EDIT*

Here is some more information that might be useful (it's a long read).

I ran into the exact same issue. After compiling without the -fexceptions build flag, the file compiled with no issue

You can run your file in http-server.

1> Have Node.js installed in your system.

2> In CMD, run the command npm install http-server -g

3> Navigate to the specific path of your file folder in CMD and run the command http-server

4> Go to your browser and type localhost:8080. Your Application should run there.

Thanks:)

If you use the library underscore you can write like this

var unionArr = _.union([34,35,45,48,49], [48,55]);_x000D_
console.log(unionArr);

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.9.1/underscore-min.js"></script>

Ref: http://underscorejs.org/#union

Here you go: http://mochajs.org/#test-level

it('accesses the network', function(done){
  this.timeout(500);
  [Put network code here, with done() in the callback]
})

For arrow function use as follows:

it('accesses the network', (done) => {
  [Put network code here, with done() in the callback]
}).timeout(500);

Read this doc which will explain to you what to do.

Setting a buildpack on an application

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

$ heroku buildpacks:set heroku/php

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

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

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

You may also specify a buildpack during app creation:

$ heroku create myapp --buildpack heroku/python

$ sudo npm i -g increase-memory-limit

Run from the root location of your project:

$ increase-memory-limit

This tool will append --max-old-space-size=4096 in all node calls inside your node_modules/.bin/* files.

Node.js version >= 8 - DEPRECATION NOTICE

Since NodeJs V8.0.0, it is possible to use the option --max-old-space-size. NODE_OPTIONS=options...

$ export NODE_OPTIONS=--max_old_space_size=4096

I've coded up a parser for the ISO 8601 standard and put it on GitHub: https://github.com/boxed/iso8601. This implementation supports everything in the specification except for durations, intervals, periodic intervals, and dates outside the supported date range of Python's datetime module.

Tests are included! :P

You have to check unique identifier column and you have to give a diff value to that particular field if you give the same value it will not work. It enforces uniqueness of the key.

One of the problems of PHP as a programming language is the fact that you can only have single inheritance. This means a class can only inherit from one other class.

However, a lot of the time it would be beneficial to inherit from multiple classes. For example, it might be desirable to inherit methods from a couple of different classes in order to prevent code duplication.

This problem can lead to class that has a long family history of inheritance which often does not make sense.

In PHP 5.4 a new feature of the language was added known as Traits. A Trait is kind of like a Mixin in that it allows you to mix Trait classes into an existing class. This means you can reduce code duplication and get the benefits whilst avoiding the problems of multiple inheritance.

Traits

Yes, it is visible in the same package. Anything outside that package will not be allowed to access it.

Have a look at this jsfiddle.

The idea is to filter rows with function which will loop through words.

jo.filter(function (i, v) {
    var $t = $(this);
    for (var d = 0; d < data.length; ++d) {
        if ($t.is(":contains('" + data[d] + "')")) {
            return true;
        }
    }
    return false;
})
//show the rows that match.
.show();

EDIT: Note that case insensitive filtering cannot be achieved using :contains() selector but luckily there's text() function so filter string should be uppercased and condition changed to if ($t.text().toUpperCase().indexOf(data[d]) > -1). Look at this jsfiddle.

This one was your solution.

$x = 0;
while($row = mysqli_fetch_array($result)) {             
    $posts[$x]['post_id'] = $row['post_id'];
    $posts[$x]['post_title'] = $row['post_title'];
    $posts[$x]['type'] = $row['type'];
    $posts[$x]['author'] = $row['author'];
    $x++;
}

Try a \<Space> before 12, like so:

:set guifont=Monospace\ 12

This answer was originally written for ASP.NET Core RC1. In RC2 ASP.NET Core moved from generic httpPlafrom handler to aspnetCore specific one. Note that step 3 depends on what version of ASP.NET Core you are using.

Turns out environment variables for ASP.NET Core projects can be set without having to set environment variables for user or having to create multiple commands entries.

1. Go to your application in IIS and choose Configuration Editor.
2. Select Configuration Editor
3. Choose system.webServer/aspNetCore (RC2 and RTM) or system.webServer/httpPlatform (RC1) in Section combobox
4. Choose Applicationhost.config ... in From combobox.
5. Right click on enviromentVariables element, select 'environmentVariables' element, then Edit Items.
6. Set your environment variables.
7. Close the window and click Apply.
8. Done

This way you do not have to create special users for your pool or create extra commands entries in project.json. Also, adding special commands for each environment breaks "build once, deploy many times" as you will have to call dnu publish separately for each environment, instead of publish once and deploying resulting artifact many times.

Updated for RC2 and RTM, thanks to Mark G and tredder.

I already did post this answer somewhere, i will do it here again. This version doesn't use any major inbuilt method. You got the char array, convert it into a String. Hope it helps!

import java.util.Scanner;

public class SentenceToWord 
{
    public static int getNumberOfWords(String sentence)
    {
        int counter=0;
        for(int i=0;i<sentence.length();i++)
        {
            if(sentence.charAt(i)==' ')
            counter++;
        }
        return counter+1;
    }

    public static char[] getSubString(String sentence,int start,int end) //method to give substring, replacement of String.substring() 
    {
        int counter=0;
        char charArrayToReturn[]=new char[end-start];
        for(int i=start;i<end;i++)
        {
            charArrayToReturn[counter++]=sentence.charAt(i);
        }
        return charArrayToReturn;
    }

    public static char[][] getWordsFromString(String sentence)
    {
        int wordsCounter=0;
        int spaceIndex=0;
        int length=sentence.length();
        char wordsArray[][]=new char[getNumberOfWords(sentence)][]; 
        for(int i=0;i<length;i++)
        {
            if(sentence.charAt(i)==' ' || i+1==length)
            {
            wordsArray[wordsCounter++]=getSubString(sentence, spaceIndex,i+1); //get each word as substring
            spaceIndex=i+1; //increment space index
            }
        }
        return  wordsArray; //return the 2 dimensional char array
    }


    public static void main(String[] args) 
    {
    System.out.println("Please enter the String");
    Scanner input=new Scanner(System.in);
    String userInput=input.nextLine().trim();
    int numOfWords=getNumberOfWords(userInput);
    char words[][]=new char[numOfWords+1][];
    words=getWordsFromString(userInput);
    System.out.println("Total number of words found in the String is "+(numOfWords));
    for(int i=0;i<numOfWords;i++)
    {
        System.out.println(" ");
        for(int j=0;j<words[i].length;j++)
        {
        System.out.print(words[i][j]);//print out each char one by one
        }
    }
    }

great code; little hint: if you sometimes have to bypass more data and not only the viewmodel ..

 if (model is ViewDataDictionary)

     controller.ViewData = model as ViewDataDictionary;
 } else {

Granted, this isn't going to provide you anything truly meaningful unless the objects have properly overriden ToString() (or you're not really working with a generic list of objects and can bind to specific fields):

List<object> objList = new List<object>();

// Fill the list

someListBox.DataSource = objList;

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

I got the error because of a clumsy typo:

This errors:

Error: attempt to apply non-function

After correcting the typo, it works:

knitr::opts_chunk$set(echo = FALSE)

There is an option in WinSCP that does exactly what you are looking for:

Exception class has two constructors

• public Exception() -- This constructs an Exception without any additional information.Nature of the exception is typically inferred from the class name.
• public Exception(String s) -- Constructs an exception with specified error message.A detail message is a String that describes the error condition for this particular exception.

Why not just use atoi? For example:

char myarray[4] = {'-','1','2','3'};

int i = atoi(myarray);

printf("%d\n", i);

Gives me, as expected:

-123

Update: why not - the character array is not null terminated. Doh!

You can skip the complex Canvas manipulation and do this entirely with Drawables, using LayerDrawable. You have one of two choices: You can either define it in XML then simply set the image, or you can configure a LayerDrawable dynamically in code.

Solution #1 (via XML):

Create a new Drawable XML file, let's call it layer.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/t" />
    <item android:drawable="@drawable/tt" />
</layer-list>

Now set the image using that Drawable:

testimage.setImageDrawable(getResources().getDrawable(R.layout.layer));

Solution #2 (dynamic):

Resources r = getResources();
Drawable[] layers = new Drawable[2];
layers[0] = r.getDrawable(R.drawable.t);
layers[1] = r.getDrawable(R.drawable.tt);
LayerDrawable layerDrawable = new LayerDrawable(layers);
testimage.setImageDrawable(layerDrawable);

(I haven't tested this code so there may be a mistake, but this general outline should work.)

The Best Order I've seen :

// SearchList is your List  
// TEXT is your Search Text
// SubList is your result

                    ArrayList<String> TempList = new ArrayList<String>(
                            (SearchList));
                    int temp = 0;
                    int num = 0;
                    ArrayList<String> SubList = new ArrayList<String>();
                    while (temp > -1) {
                        temp = TempList.indexOf(new Object() {
                            @Override
                            public boolean equals(Object obj) {
                                return obj.toString().startsWith(TEXT);
                            }
                        });
                        if (temp > -1) {
                         SubList.add(SearchList.get(temp + num++));
                         TempList.remove(temp);
                        }
                    }

Input the following to your Apache configuration:

Hope this useful for you.

});

For your first array example use,

a = numpy.arange(5)

To initialize big_array, use

big_array = numpy.zeros((10,4))

This assumes you want to initialize with zeros, which is pretty typical, but there are many other ways to initialize an array in numpy.

Edit: If you don't know the size of big_array in advance, it's generally best to first build a Python list using append, and when you have everything collected in the list, convert this list to a numpy array using numpy.array(mylist). The reason for this is that lists are meant to grow very efficiently and quickly, whereas numpy.concatenate would be very inefficient since numpy arrays don't change size easily. But once everything is collected in a list, and you know the final array size, a numpy array can be efficiently constructed.

Suppose your data looks like this:

import pandas as pd
import numpy as np

np.random.seed(2015)
df = pd.DataFrame([])
for i in range(5):
    data = dict(zip(np.random.choice(10, replace=False, size=5),
                    np.random.randint(10, size=5)))
    data = pd.DataFrame(data.items())
    data = data.transpose()
    data.columns = data.iloc[0]
    data = data.drop(data.index[[0]])
    df = df.append(data)
print('{}\n'.format(df))
# 0   0   1   2   3   4   5   6   7   8   9
# 1   6 NaN NaN   8   5 NaN NaN   7   0 NaN
# 1 NaN   9   6 NaN   2 NaN   1 NaN NaN   2
# 1 NaN   2   2   1   2 NaN   1 NaN NaN NaN
# 1   6 NaN   6 NaN   4   4   0 NaN NaN NaN
# 1 NaN   9 NaN   9 NaN   7   1   9 NaN NaN

Then it could be replaced with

np.random.seed(2015)
data = []
for i in range(5):
    data.append(dict(zip(np.random.choice(10, replace=False, size=5),
                         np.random.randint(10, size=5))))
df = pd.DataFrame(data)
print(df)

In other words, do not form a new DataFrame for each row. Instead, collect all the data in a list of dicts, and then call df = pd.DataFrame(data) once at the end, outside the loop.

Each call to df.append requires allocating space for a new DataFrame with one extra row, copying all the data from the original DataFrame into the new DataFrame, and then copying data into the new row. All that allocation and copying makes calling df.append in a loop very inefficient. The time cost of copying grows quadratically with the number of rows. Not only is the call-DataFrame-once code easier to write, it's performance will be much better -- the time cost of copying grows linearly with the number of rows.

I had the same problem with JWebUnit. Please notice that if you use binary distribution then Logback is a default logger. To use log4j with JWebUnit I performed following steps:

• removed Logback jars
• add lod4j bridge library for sfl4j - slf4j-log4j12-1.6.4.jar
• add log4j.properties

Probably you don't have to remove Logback jars but you will need some additional step to force slf4j to use log4j

In your JSON format, it do not have starting JSON object

Like :

{
    "info" :       <!-- this is starting JSON object -->
        {
        "caller":"getPoiById",
        "results":
        {
            "indexForPhone":0,
            "indexForEmail":"NULL",
            .
            .
         }
    }
}

Above Json starts with info as JSON object. So while executing :

JSONObject json = new JSONObject(result);    // create JSON obj from string
JSONObject json2 = json.getJSONObject("info");    // this will return correct

Now, we can access result field :

JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"

I think this was missing and so the problem was solved while we use JSONTokener like answer of yours.

Your answer is very fine. Just i think i add this information so i answered

Thank you

If you want to avoid the memory expense of converting to a series of tuples or another similar data structure, you can exploit numpy's structured arrays.

The trick is to view your original array as a structured array where each item corresponds to a row of the original array. This doesn't make a copy, and is quite efficient.

As a quick example:

import numpy as np

data = np.array([[1, 1, 1, 0, 0, 0],
                 [0, 1, 1, 1, 0, 0],
                 [0, 1, 1, 1, 0, 0],
                 [1, 1, 1, 0, 0, 0],
                 [1, 1, 1, 1, 1, 0]])

ncols = data.shape[1]
dtype = data.dtype.descr * ncols
struct = data.view(dtype)

uniq = np.unique(struct)
uniq = uniq.view(data.dtype).reshape(-1, ncols)
print uniq

To understand what's going on, have a look at the intermediary results.

Once we view things as a structured array, each element in the array is a row in your original array. (Basically, it's a similar data structure to a list of tuples.)

In [71]: struct
Out[71]:
array([[(1, 1, 1, 0, 0, 0)],
       [(0, 1, 1, 1, 0, 0)],
       [(0, 1, 1, 1, 0, 0)],
       [(1, 1, 1, 0, 0, 0)],
       [(1, 1, 1, 1, 1, 0)]],
      dtype=[('f0', '<i8'), ('f1', '<i8'), ('f2', '<i8'), ('f3', '<i8'), ('f4', '<i8'), ('f5', '<i8')])

In [72]: struct[0]
Out[72]:
array([(1, 1, 1, 0, 0, 0)],
      dtype=[('f0', '<i8'), ('f1', '<i8'), ('f2', '<i8'), ('f3', '<i8'), ('f4', '<i8'), ('f5', '<i8')])

Once we run numpy.unique, we'll get a structured array back:

In [73]: np.unique(struct)
Out[73]:
array([(0, 1, 1, 1, 0, 0), (1, 1, 1, 0, 0, 0), (1, 1, 1, 1, 1, 0)],
      dtype=[('f0', '<i8'), ('f1', '<i8'), ('f2', '<i8'), ('f3', '<i8'), ('f4', '<i8'), ('f5', '<i8')])

That we then need to view as a "normal" array (_ stores the result of the last calculation in ipython, which is why you're seeing _.view...):

In [74]: _.view(data.dtype)
Out[74]: array([0, 1, 1, 1, 0, 0, 1, 1, 1, 0, 0, 0, 1, 1, 1, 1, 1, 0])

And then reshape back into a 2D array (-1 is a placeholder that tells numpy to calculate the correct number of rows, give the number of columns):

In [75]: _.reshape(-1, ncols)
Out[75]:
array([[0, 1, 1, 1, 0, 0],
       [1, 1, 1, 0, 0, 0],
       [1, 1, 1, 1, 1, 0]])

Obviously, if you wanted to be more concise, you could write it as:

import numpy as np

def unique_rows(data):
    uniq = np.unique(data.view(data.dtype.descr * data.shape[1]))
    return uniq.view(data.dtype).reshape(-1, data.shape[1])

data = np.array([[1, 1, 1, 0, 0, 0],
                 [0, 1, 1, 1, 0, 0],
                 [0, 1, 1, 1, 0, 0],
                 [1, 1, 1, 0, 0, 0],
                 [1, 1, 1, 1, 1, 0]])
print unique_rows(data)

Which results in:

[[0 1 1 1 0 0]
 [1 1 1 0 0 0]
 [1 1 1 1 1 0]]

I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).

MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.

// Merge object2 into object1, recursively

.a files are created with the ar utility, and they are libraries. To use it with gcc, collect all .a files in a lib/ folder and then link with -L lib/ and -l<name of specific library>.

Collection of all .a files into lib/ is optional. Doing so makes for better looking directories with nice separation of code and libraries, IMHO.

Actually you can do this.

$state.go("state-name", {param-name: param-value}, {location: false, inherit: false});

This is the official documentation about options in state.go

Everything is described there and as you can see this is the way to be done.

I've published a Python [3] tree implementation on my site: http://www.quesucede.com/page/show/id/python_3_tree_implementation.

Hope it is of use,

Ok, here's the code:

import uuid

def sanitize_id(id):
    return id.strip().replace(" ", "")

(_ADD, _DELETE, _INSERT) = range(3)
(_ROOT, _DEPTH, _WIDTH) = range(3)

class Node:

    def __init__(self, name, identifier=None, expanded=True):
        self.__identifier = (str(uuid.uuid1()) if identifier is None else
                sanitize_id(str(identifier)))
        self.name = name
        self.expanded = expanded
        self.__bpointer = None

If you add a $scope.$apply(); right after $scope.pluginsDisplayed.splice(index,1); then it works.

I am not sure why this is happening, but basically when AngularJS doesn't know that the $scope has changed, it requires to call $apply manually. I am also new to AngularJS so cannot explain this better. I need too look more into it.

I found this awesome article that explains it quite properly. Note: I think it might be better to use ng-click (docs) rather than binding to "mousedown". I wrote a simple app here (http://avinash.me/losh, source http://github.com/hardfire/losh) based on AngularJS. It is not very clean, but it might be of help.

I use this code ...

 function rmDirectory($dir) {
        foreach(glob($dir . '/*') as $file) {
            if(is_dir($file))
                rrmdir($file);
            else
                unlink($file);
        }
        rmdir($dir);
    }

or this one...

<?php 
public static function delTree($dir) { 
   $files = array_diff(scandir($dir), array('.','..')); 
    foreach ($files as $file) { 
      (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
    } 
    return rmdir($dir); 
  } 
?>

I resolved this issue by using the code below. Please do not use other parameters in these functions.

mWorkBook = xlApp.Workbooks.Open(FilePath)

mWorkBook.Save();

RESOLVED

You can use jQuery to achieve this using simple $.get method. .html work like innerHtml and replace the content of your div.

$.get("/YourUrl", {},
      function (returnedHtml) {
      $("#here").html(returnedHtml);
});

And call this using javascript setInterval method.

Not really. See File input 'accept' attribute - is it useful? .

This happens when you update from Chrome 55 to Chrome 56 (56.0.2924.87).
This is an increase in security enforcement.
It doesn't go away by restarting the browser, and it's not a bug.

Mountain View says it's hoping you don't ever encounter the message, because Certificate Authorities are required to stop issuing SHA-1 certificates in 2016. Just in case, Google plans to continue issuing warnings until Chrome completely stops supporting SHA-1 on January 1st, 2017. When that day comes, a website that still uses the function will trigger a fatal network error. (Source: Engadget.com)

If this happens, the most-likely cause is that your (or the website's) SSL-certificate uses SHA1.
SHA1 is broken, and SSL certificates using SHA1 are not secure anymore (it's now been a long time that Chrome showed this to you - now it blocks NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM).

Another likely cause is that your SSL-certificate expired
Also, you should disable backwards-compatiblity with SSL2 & SSL3 (Poodle Attack).
You should only be using TLS (SSL 3.1+).

To test your domain's SSL-certificate, you can use SSL labs SSL test.

To find out what exactly the issue is: Open the chrome developer console (CTRL + SHIFT + J OR F12) And change to the security tab

For more information:
https://support.google.com/chrome/answer/95617?visit_id=1-636221396724527190-3454695657&p=ui_security_indicator&rd=1

FYI:

SHA-1 has been growing weaker and more insecure everyday for a decade now, which is dangerous considering we tend to trust websites with "https://" in their URLs. Other browsers like Mozilla Firefox and Microsoft Edge also plan to stop supporting it in an effort to encourage website owners to switch to more secure SHA-2 certificates as soon as possible.

If you urgently need to get around it (you need to close all running instances of Chrome first - otherwise it won't work):

chrome --args --ignore-certificate-errors

Please note: don't go online-banking or gmail'ing with those command-line settings active in your Chrome instance.

In case your app needs to work on files (what you would normally expect to pass as: ./myApp *.jpg), you would do it like this:

open *.jpg -a myApp

You don't specify a type. The method will only fail (at runtime) if it tries to access attributes that are not defined on the parameters that are passed in.

So this simple function:

def no_op(param1, param2):
    pass

... will not fail no matter what two args are passed in.

However, this function:

def call_quack(param1, param2):
    param1.quack()
    param2.quack()

... will fail at runtime if param1 and param2 do not both have callable attributes named quack.

String Interpolation

is a concept that languages like Perl have had for quite a while, and now we’ll get this ability in C# as well. In String Interpolation, we simply prefix the string with a $ (much like we use the @ for verbatim strings). Then, we simply surround the expressions we want to interpolate with curly braces (i.e. { and }):

It looks a lot like the String.Format() placeholders, but instead of an index, it is the expression itself inside the curly braces. In fact, it shouldn’t be a surprise that it looks like String.Format() because that’s really all it is – syntactical sugar that the compiler treats like String.Format() behind the scenes.

A great part is, the compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

C# string interpolation is a method of concatenating,formatting and manipulating strings. This feature was introduced in C# 6.0. Using string interpolation, we can use objects and expressions as a part of the string interpolation operation.

Syntax of string interpolation starts with a ‘$’ symbol and expressions are defined within a bracket {} using the following syntax.

{<interpolatedExpression>[,<alignment>][:<formatString>]}  

Where:

• interpolatedExpression - The expression that produces a result to be formatted
• alignment - The constant expression whose value defines the minimum number of characters in the string representation of the result of the interpolated expression. If positive, the string representation is right-aligned; if negative, it's left-aligned.
• formatString - A format string that is supported by the type of the expression result.

The following code example concatenates a string where an object, author as a part of the string interpolation.

string author = "Mohit";  
string hello = $"Hello {author} !";  
Console.WriteLine(hello);  // Hello Mohit !

Read more on C#/.NET Little Wonders: String Interpolation in C# 6

As pointed out in answers above

my_string.strip()

will remove all the leading and trailing whitespace characters such as \n, \r, \t, \f, space .

For more flexibility use the following

• Removes only leading whitespace chars: my_string.lstrip()
• Removes only trailing whitespace chars: my_string.rstrip()
• Removes specific whitespace chars: my_string.strip('\n') or my_string.lstrip('\n\r') or my_string.rstrip('\n\t') and so on.

More details are available in the docs.

You can replace the special characters with the desired characters as follows,

import string
specialCharacterText = "H#y #@w @re &*)?"
inCharSet = "!@#$%^&*()[]{};:,./<>?\|`~-=_+\""
outCharSet = "                               " #corresponding characters in inCharSet to be replaced
splCharReplaceList = string.maketrans(inCharSet, outCharSet)
splCharFreeString = specialCharacterText.translate(splCharReplaceList)

import numpy
print numpy.__version__

See my detailed answer to a very similar previous question

@Beau Crawford's is a good way in SQL 2005 and below, though if you're granting rep it should go to the first guy to SO it. The only problem is that for inserts it's still two IO operations.

MS Sql2008 introduces merge from the SQL:2003 standard:

merge tablename with(HOLDLOCK) as target
using (values ('new value', 'different value'))
    as source (field1, field2)
    on target.idfield = 7
when matched then
    update
    set field1 = source.field1,
        field2 = source.field2,
        ...
when not matched then
    insert ( idfield, field1, field2, ... )
    values ( 7,  source.field1, source.field2, ... )

Now it's really just one IO operation, but awful code :-(

As in Swift 3.x for upload image with parameter we can use below alamofire upload method-

static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {

        let imageData = UIImageJPEGRepresentation(imageFile , 0.5)

        Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")

            for key in parameters.keys{
                let name = String(key)
                if let val = parameters[name!] as? String{
                    multipartFormData.append(val.data(using: .utf8)!, withName: name!)
                }
            }
        }, to:inputUrl)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (Progress) in
                })

                upload.responseJSON { response in

                    if let JSON = response.result.value {
                        completion(JSON)
                    }else{
                        completion(nilValue)
                    }
                }

            case .failure(let encodingError):
                completion(nilValue)
            }

        }

    }

Note: Additionally if our parameter is array of key-pairs then we can use

 var arrayOfKeyPairs = [[String:Any]]()
 let json = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
 let jsonPresentation = String(data: json!, encoding: .utf8)

Sometimes, it may help switching off AllowAutoRedirect and setting both login POST and page GET requests the same user agent.

request.UserAgent = userAgent;
request.AllowAutoRedirect = false;

var arr = [
  {
  "id": "1",
  "msg": "hi",
  "tid": "2013-05-05 23:35",
  "fromWho": "[email protected]"
  }, {
  "id": "2",
  "msg": "there",
  "tid": "2013-05-05 23:45",
  "fromWho": "[email protected]"
  }
];

forEach method for easy implementation.

arr.forEach(function(item){
  console.log('ID: ' + item.id);
  console.log('MSG: ' + item.msg);
  console.log('TID: ' + item.tid);
  console.log('FROMWHO: ' + item.fromWho);
});

data1.reset_index(inplace=True)

You can use switch-case fall through by omitting the break; statement.

char c = /* whatever */;

switch(c) {
    case 'a':
    case 'A':
        //get the 'A' image;
        break;
    case 'b':
    case 'B':
        //get the 'B' image;
        break;
    // (...)
    case 'z':
    case 'Z':
        //get the 'Z' image;
        break;
}

...or you could just normalize to lower case or upper case before switching.

char c = Character.toUpperCase(/* whatever */);

switch(c) {
    case 'A':
        //get the 'A' image;
        break;
    case 'B':
        //get the 'B' image;
        break;
    // (...)
    case 'Z':
        //get the 'Z' image;
        break;
}

Talking specifically about textareas in web forms, for all textareas, on all platforms, \r\n will work.

If you use anything else you will cause issues with cut and paste on Windows platforms.

The line breaks will be canonicalised by windows browsers when the form is submitted, but if you send the form down to the browser with \n linebreaks, you will find that the text will not copy and paste correctly between for example notepad and the textarea.

Interestingly, in spite of the Unix line end convention being \n, the standard in most text-based network protocols including HTTP, SMTP, POP3, IMAP, and so on is still \r\n. Yes, it may not make a lot of sense, but that's history and evolving standards for you!

When you write your main function, you typically see one of two definitions:

• int main(void)
• int main(int argc, char **argv)

The second form will allow you to access the command line arguments passed to the program, and the number of arguments specified (arguments are separated by spaces).

The arguments to main are:

• int argc - the number of arguments passed into your program when it was run. It is at least 1.
• char **argv - this is a pointer-to-char *. It can alternatively be this: char *argv[], which means 'array of char *'. This is an array of C-style-string pointers.

Basic Example

For example, you could do this to print out the arguments passed to your C program:

#include <stdio.h>

int main(int argc, char **argv)
{
    for (int i = 0; i < argc; ++i)
    {
        printf("argv[%d]: %s\n", i, argv[i]);
    }
}

I'm using GCC 4.5 to compile a file I called args.c. It'll compile and build a default a.out executable.

[birryree@lilun c_code]$ gcc -std=c99 args.c

Now run it...

[birryree@lilun c_code]$ ./a.out hello there
argv[0]: ./a.out
argv[1]: hello
argv[2]: there

So you can see that in argv, argv[0] is the name of the program you ran (this is not standards-defined behavior, but is common. Your arguments start at argv[1] and beyond.

So basically, if you wanted a single parameter, you could say...

./myprogram integral

A Simple Case for You

And you could check if argv[1] was integral, maybe like strcmp("integral", argv[1]) == 0.

So in your code...

#include <stdio.h>
#include <string.h>

int main(int argc, char **argv)
{
    if (argc < 2) // no arguments were passed
    {
        // do something
    }

    if (strcmp("integral", argv[1]) == 0)
    {
        runIntegral(...); //or something
    }
    else
    {
        // do something else.
    }
}

Better command line parsing

Of course, this was all very rudimentary, and as your program gets more complex, you'll likely want more advanced command line handling. For that, you could use a library like GNU getopt.

on the p element, add 3 styling rules.

.myCenteredPElement{
    margin-left:  auto;
    margin-right: auto;
    text-align: center;
}

i found i had to do something akin to

=(countifs (A1:A196,"yes", j1:j196, "agree") + (countifs (A1:A196,"no", j1:j196, "agree"))

For python 3.8.6/3.9, I had to do some dirty hacks, because perfplot was giving out some errors. Here assume that x[0] is a a and x[1] is b:

The plot is nearly same for large data. For small data,

Taken by perfplot and this is the code, large data == range(8), small data == range(4).

import perfplot

from random import choice
from string import ascii_lowercase as letters

def generate_random(x):
    data = ''.join(choice(letters) for i in range(x))
    sata = ''.join(choice(letters) for i in range(x))
    return [data,sata]

def fstring_func(x):
    return [ord(i) for i in f'{x[0]}{x[1]}']

def format_func(x):
    return [ord(i) for i in "{}{}".format(x[0], x[1])]

def replace_func(x):
    return [ord(i) for i in "|~".replace('|', x[0]).replace('~', x[1])]

def join_func(x):
    return [ord(i) for i in "".join([x[0], x[1]])]

perfplot.show(
    setup=lambda n: generate_random(n),
    kernels=[
        fstring_func,
        format_func,
        replace_func,
        join_func,
    ],
    n_range=[int(k ** 2.5) for k in range(4)],
)

When medium data is there, and 4 strings are there x[0], x[1], x[2], x[3] instead of 2 string:

def generate_random(x):
    a =  ''.join(choice(letters) for i in range(x))
    b =  ''.join(choice(letters) for i in range(x))
    c =  ''.join(choice(letters) for i in range(x))
    d =  ''.join(choice(letters) for i in range(x))
    return [a,b,c,d]

Better to stick with fstrings

From python >= 3.5 onward, you can use **, glob.iglob(path/**, recursive=True) and it seems the most pythonic solution, i.e.:

import glob, os

for filename in glob.iglob('/pardadox-music/**', recursive=True):
    if os.path.isfile(filename): # filter dirs
        print(filename)

Output:

/pardadox-music/modules/her1.mod
/pardadox-music/modules/her2.mod
...

Notes:
1 - glob.iglob

glob.iglob(pathname, recursive=False)

Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

2 - If recursive is True, the pattern '**' will match any files and zero or more directories and subdirectories.

3 - If the directory contains files starting with . they won’t be matched by default. For example, consider a directory containing card.gif and .card.gif:

>>> import glob
>>> glob.glob('*.gif') ['card.gif'] 
>>> glob.glob('.c*')['.card.gif']

4 - You can also use rglob(pattern), which is the same as calling glob() with **/ added in front of the given relative pattern.

I'm not saying that there's anything wrong with your question or the answer given, but maybe you'd like to know about the wonderful tool that is Hoogle to save yourself time in the future: With Hoogle, you can search for standard library functions that match a given signature. So, not knowing anything about !!, in your case you might search for "something that takes an Int and a list of whatevers and returns a single such whatever", namely

Int -> [a] -> a

Lo and behold, with !! as the first result (although the type signature actually has the two arguments in reverse compared to what we searched for). Neat, huh?

Also, if your code relies on indexing (instead of consuming from the front of the list), lists may in fact not be the proper data structure. For O(1) index-based access there are more efficient alternatives, such as arrays or vectors.

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

You need to either use ng-bind-html-unsafe ... or you need to include the ngSanitize module and use ng-bind-html:

with ng-bind-html-unsafe

Use this if you trust the source of the HTML you're rendering it will render the raw output of whatever you put into it.

<div><h4>Categories</h4><span ng-bind-html-unsafe="q.CATEGORY"></span></div>

OR with ng-bind-html

Use this if you DON'T trust the source of the HTML (i.e. it's user input). It will sanitize the html to make sure it doesn't include things like script tags or other sources of potential security risks.

Make sure you include this:

<script src="http://code.angularjs.org/1.0.4/angular-sanitize.min.js"></script>

Then reference it in your application module:

var app = angular.module('myApp', ['ngSanitize']);

THEN use it:

<div><h4>Categories</h4><span ng-bind-html="q.CATEGORY"></span></div>

You have to change the mamp Mysql Database port into 8889.

In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:

<button (click)="navigateToResource()">Navigate</button>

And in my component.ts

navigateToResource(): void {
  this.service.getUrl((result: any) => window.open(result.url));
}

Note:

Routing to a link indirectly like this will likely trigger the browser's popup blocker.

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

I would use this kind of function for speed:

def check_string(string, substring_list):
    for substring in substring_list:
        if substring in string:
            return True
    return False

One of simplest solution is to change colorPrimary from colors.xml file.
