I suppose https://get-ytt.io/ would be an acceptable solution to your problem

In the job configuration one can define various build triggers. With periodically build you can schedule the build by defining the date or day of the week and the time to execute the build.

The format is as follows:

MINUTE (0-59), HOUR (0-23), DAY (1-31), MONTH (1-12), DAY OF THE WEEK (0-6)

The letter H, representing the word Hash can be inserted instead of any of the values, it will calculate the parameter based on the hash code of your project name, this is so that if you are building several projects on your build machine at the same time, lets say midnight each day, they do not all start there build execution at the same time, each project starts its execution at a different minute depending on its hash code. You can also specify the value to be between numbers, i.e. H(0,30) will return the hash code of the project where the possible hashes are 0-30

Examples:

start build daily at 08:30 in the morning, Monday - Friday:

• 30 08 * * 1-5

weekday daily build twice a day, at lunchtime 12:00 and midnight 00:00, Sunday to Thursday:

• 00 0,12 * * 0-4

start build daily in the late afternoon between 4:00 p.m. - 4:59 p.m. or 16:00 -16:59 depending on the projects hash:

• H 16 * * 1-5

start build at midnight:

• @midnight

or start build at midnight, every Saturday:

• 59 23 * * 6

every first of every month between 2:00 a.m. - 02:30 a.m. :

• H(0-30) 02 01 * *

The solution of prijin worked perfectly for me. It is just fair to mention that two additional permissions are needed:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

When these are added, enabling and disabling works flawless with the default bluetooth adapter.

If you ever get such an interview question (or notice some equally unexpected behavior in your code) think about what kind of things could possibly cause a behavior that looks impossible at first glance:

1. Encoding: In this case the variable you are looking at is not the one you think it is. This can happen if you intentionally mess around with Unicode using homoglyphs or space characters to make the name of a variable look like another one, but encoding issues can also be introduced accidentally, e.g. when copying & pasting code from the Web that contains unexpected Unicode code points (e.g. because a content management system did some "auto-formatting" such as replacing fl with Unicode 'LATIN SMALL LIGATURE FL' (U+FB02)).

2. Race conditions: A race-condition might occur, i.e. a situation where code is not executing in the sequence expected by the developer. Race conditions often happen in multi-threaded code, but multiple threads are not a requirement for race conditions to be possible – asynchronicity is sufficient (and don't get confused, async does not mean multiple threads are used under the hood).

   Note that therefore JavaScript is also not free from race conditions just because it is single-threaded. See here for a simple single-threaded – but async – example. In the context of an single statement the race condition however would be rather hard to hit in JavaScript.

   JavaScript with web workers is a bit different, as you can have multiple threads. @mehulmpt has shown us a great proof-of-concept using web workers.

3. Side-effects: A side-effect of the equality comparison operation (which doesn't have to be as obvious as in the examples here, often side-effects are very subtle).

These kind of issues can appear in many programming languages, not only JavaScript, so we aren't seeing one of the classical JavaScript WTFs here¹.

Of course, the interview question and the samples here all look very contrived. But they are a good reminder that:

• Side-effects can get really nasty and that a well-designed program should be free from unwanted side-effects.
• Multi-threading and mutable state can be problematic.
• Not doing character encoding and string processing right can lead to nasty bugs.

_{¹ For example, you can find an example in a totally different programming language (C#) exhibiting a side-effect (an obvious one) here.}

In VB code, when trying to submit an INSERT query, you must submit a double query in the same 'executenonquery' like this:

sqlQuery = "SET IDENTITY_INSERT dbo.TheTable ON; INSERT INTO dbo.TheTable (Col1, COl2) VALUES (Val1, Val2); SET IDENTITY_INSERT dbo.TheTable OFF;"

I used a ; separator instead of a GO.

Works for me. Late but efficient!

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
} 

This is the best practice. This way you will get the variables from GET method as well as POST method

    public function index(Request $request) {
            $data=$request->all();
            dd($data);
    }
//OR if you want few of them then
    public function index(Request $request) {
            $data=$request->only('id','name','etc');
            dd($data);
    }
//OR if you want all except few then
    public function index(Request $request) {
            $data=$request->except('__token');
            dd($data);
    }

Angular CLI version 9 (used to create Angular 9 projects) now picks up style from schematics instead of styleext. Use the command like this:
ng config schematics.@schematics/angular:component.style scss
and the resulting angular.json shall look like this

"schematics": {
   "@schematics/angular:component": {
      "style": "scss"
    }
  }

Other possible solutions & explanations:

To create a new project with angular CLI with sass support, try this:

ng new My_New_Project --style=scss 

You can also use --style=sass & if you don't know the difference, read this short & easy article and if you still don't know, just go with scss & keep learning.

If you have an angular 5 project, use this command to update the config for your project.

ng set defaults.styleExt scss

For Latest Versions

For Angular 6 to set new style on existing project with CLI:

ng config schematics.@schematics/angular:component.styleext scss

Or Directly into angular.json:

"schematics": {
      "@schematics/angular:component": {
      "styleext": "scss"
    }
}

With mailx you can do:

mailx -s "My Subject"  -a ./mail_att.csv -S [email protected]  [email protected] < ./mail_body.txt

This worked great on our GNU Linux servers, but unfortunately my dev environment is Mac OsX which only has a crummy old BSD version of mailx. Normally I use Coreutils to get better versions of unix commands than the Mac BSD ones, but mailx is not in Coreutils.

I found a solution from notpeter in an unrelated thread (https://serverfault.com/questions/196001/using-unix-mail-mailx-with-a-modern-mail-server-imap-instead-of-mbox-files) which was to download the Heirloom mailx OSX binary package from http://www.tramm.li/iWiki/HeirloomNotes.html. It has a more featured mailx which can handle the above command syntax.

Here's the complete clean and optimised code in JAVA 8

            if(arr[j] == arr[i])
            {
                ++count;
            }

            if(count > maxCount)
            {
                maxCount = count;
                maxValue = arr[i];
            }
        }
    } 
    System.out.println(maxValue);
   //////////////mode code ends here//////////////////

  }

}

Vanilla JS

document.getElementById("textareaID").value

jQuery

$("#textareaID").val()

Cannot do the other way round (it's always good to know what you're doing)

document.getElementById("textareaID").value() // --> TypeError: Property 'value' of object #<HTMLTextAreaElement> is not a function

jQuery:

$("#textareaID").value // --> undefined

Your example as written works perfectly in Chrome 11 for me. Perhaps your browser just doesn't support the :not() selector?

You may need to use JavaScript or similar to accomplish this cross-browser. jQuery implements :not() in its selector API.

I had referenced this article and many others and did not find a clear cut concise response to help. I am offering my discovery, arrived at with some references from this thread, in the following:

Spring-Boot version: 1.3.5.RELEASE

Spring-Core version: 4.2.6.RELEASE

Dependency Management: Brixton.SR1

The following is the pertinent yaml excerpt:

tools:
  toolList:
    - 
      name: jira
      matchUrl: http://someJiraUrl
    - 
      name: bamboo
      matchUrl: http://someBambooUrl

I created a Tools.class:

@Component
@ConfigurationProperties(prefix = "tools")
public class Tools{
    private List<Tool> toolList = new ArrayList<>();
    public Tools(){
      //empty ctor
    }

    public List<Tool> getToolList(){
        return toolList;
    }

    public void setToolList(List<Tool> tools){
       this.toolList = tools;
    }
}

I created a Tool.class:

@Component
public class Tool{
    private String name;
    private String matchUrl;

    public Tool(){
      //empty ctor
    }

    public String getName(){
        return name;
    }

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

    public void setMatchUrl(String matchUrl){
       this.matchUrl= matchUrl;
    }

    @Override
    public String toString(){
        StringBuffer sb = new StringBuffer();
        String ls = System.lineSeparator();
        sb.append(ls);
        sb.append("name:  " + name);
        sb.append(ls);
        sb.append("matchUrl:  " + matchUrl);
        sb.append(ls);
    }
}

I used this combination in another class through @Autowired

@Component
public class SomeOtherClass{

   private Logger logger = LoggerFactory.getLogger(SomeOtherClass.class);

   @Autowired
   private Tools tools;

   /* excluded non-related code */

   @PostConstruct
   private void init(){
       List<Tool>  toolList = tools.getToolList();
       if(toolList.size() > 0){
           for(Tool t: toolList){
               logger.info(t.toString());
           }
       }else{
           logger.info("*****-----     tool size is zero     -----*****");
       }  
   }

   /* excluded non-related code */

}

And in my logs the name and matching url's were logged. This was developed on another machine and thus I had to retype all of the above so please forgive me in advance if I inadvertently mistyped.

I hope this consolidation comment is helpful to many and I thank the previous contributors to this thread!

Instead of reinventing the wheel go with envsubst Can be used in almost any scenario, for instance building configuration files from environment variables in docker containers.

If on mac make sure you have homebrew then link it from gettext:

brew install gettext
brew link --force gettext

./template.cfg

# We put env variables into placeholders here
this_variable_1 = ${SOME_VARIABLE_1}
this_variable_2 = ${SOME_VARIABLE_2}

./.env:

SOME_VARIABLE_1=value_1
SOME_VARIABLE_2=value_2

./configure.sh

#!/bin/bash
cat template.cfg | envsubst > whatever.cfg

Now just use it:

# make script executable
chmod +x ./configure.sh
# source your variables
. .env
# export your variables
# In practice you may not have to manually export variables 
# if your solution depends on tools that utilise .env file 
# automatically like pipenv etc. 
export SOME_VARIABLE_1 SOME_VARIABLE_2
# Create your config file
./configure.sh

I am going to use a very simple snippet to illustrate the difference:

test = pd.DataFrame({'id':[1,2,3,1,2,3,1,2,3], 'price':[1,2,3,2,3,1,3,1,2]})
grouping = test.groupby('id')['price']

The DataFrame looks like this:

    id  price   
0   1   1   
1   2   2   
2   3   3   
3   1   2   
4   2   3   
5   3   1   
6   1   3   
7   2   1   
8   3   2   

There are 3 customer IDs in this table, each customer made three transactions and paid 1,2,3 dollars each time.

Now, I want to find the minimum payment made by each customer. There are two ways of doing it:

1. Using apply:

   grouping.min()

The return looks like this:

id
1    1
2    1
3    1
Name: price, dtype: int64

pandas.core.series.Series # return type
Int64Index([1, 2, 3], dtype='int64', name='id') #The returned Series' index
# lenght is 3

2. Using transform:

   grouping.transform(min)

The return looks like this:

0    1
1    1
2    1
3    1
4    1
5    1
6    1
7    1
8    1
Name: price, dtype: int64

pandas.core.series.Series # return type
RangeIndex(start=0, stop=9, step=1) # The returned Series' index
# length is 9    

Both methods return a Series object, but the length of the first one is 3 and the length of the second one is 9.

If you want to answer What is the minimum price paid by each customer, then the apply method is the more suitable one to choose.

If you want to answer What is the difference between the amount paid for each transaction vs the minimum payment, then you want to use transform, because:

test['minimum'] = grouping.transform(min) # ceates an extra column filled with minimum payment
test.price - test.minimum # returns the difference for each row

Apply does not work here simply because it returns a Series of size 3, but the original df's length is 9. You cannot integrate it back to the original df easily.

I had the same issue and I have found a library that does the job : https://github.com/pleerock/class-transformer.

It works like this :

let jsonObject = response.json() as Object;
let fooInstance = plainToClass(Models.Foo, jsonObject);
return fooInstance;

It supports nested childs but you have to decorate your class's member.

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

To keep the scripting in one place rather than using onClick in the HTML tag, add the following code to your script block:

$('#id-of-the-button').click(function() {document.forms[0].submit()});

Which assumes you just have the one form on the page.

This way it worked for me:

var noticias = from n in db.Noticias.Take(6)
                       where n.Atv == 1
                       orderby n.DatHorLan descending
                       select n;

They're equivalent. The access is the same.

The import is just a convention to save you from having to type the fully-resolved class name each time. You can write all your Java without using import, as long as you're a fast touch typer.

But there's no difference in efficiency or class loading.

import sys, os

try:
    raise NotImplementedError("No error")
except Exception as e:
    exc_type, exc_obj, exc_tb = sys.exc_info()
    fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
    print(exc_type, fname, exc_tb.tb_lineno)

The "no frills" options are as follows:

ActiveSheet.Name = "New Name"

and

Sheets("Sheet2").Name = "New Name"

You can also check out recording macros and seeing what code it gives you, it's a great way to start learning some of the more vanilla functions.

with open("Stud.txt", "rt") as fin:
    with open("out.txt", "wt") as fout:
        for line in fin:
            fout.write(line.replace('A', 'Orange'))

There are two types of drop down lists available (I am not sure since which version).

ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.

Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.

Try this (its work in Chrome, Firefox and IE):

... content in page 1 ...
<p style="page-break-after: always;">&nbsp;</p>
<p style="page-break-before: always;">&nbsp;</p>
... content in page 2 ...

I believe that echo outputs a trailing newline. Try using -n as a parameter to echo to skip the newline.

I have a solution which works well but instead an ellipsis it uses a gradient. It works when you have dynamic text so you don't know if it will be long enough to need an ellipse. The advantages are that you don't have to do any JavaScript calculations and it works for variable width containers including table cells and is cross-browser. It uses a couple of extra divs, but it's very easy to implement.

Markup:

<td>
    <div class="fade-container" title="content goes here">
         content goes here
         <div class="fade">
    </div>
</td>

CSS:

.fade-container { /*two lines*/
    overflow: hidden;
    position: relative;
    line-height: 18px; 
    /* height must be a multiple of line-height for how many rows you want to show (height = line-height x rows) */
    height: 36px;
    -ms-hyphens: auto;
    -webkit-hyphens: auto;
    hyphens: auto;
    word-wrap: break-word;
}

.fade {
        position: absolute;
        top: 50%;/* only cover the last line. If this wrapped to 3 lines it would be 33% or the height of one line */
        right: 0;
        bottom: 0;
        width: 26px;
        background: linear-gradient(to right,  rgba(255,255,255,0) 0%,rgba(255,255,255,1) 100%);
}

The problem is that [...] in python has two distinct meanings

1. expr [ index ] means accessing an element of a list
2. [ expr1, expr2, expr3 ] means building a list of three elements from three expressions

In your code you forgot the comma between the expressions for the items in the outer list:

[ [a, b, c] [d, e, f] [g, h, i] ]

therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.

The correct syntax for what you're looking for is

[ [a, b, c], [d, e, f], [g, h, i] ]

Just comment all lines in first Directory. Or you can remove these lines, but better to keep in case later you want to add some restrictions, you will uncomment.

#<Directory /usr/share/phpMyAdmin/>
#   <IfModule mod_authz_core.c>
#     # Apache 2.4
#     <RequireAny>
#       Require ip 127.0.0.1
#       Require ip ::1
#     </RequireAny>
#   </IfModule>
#   <IfModule !mod_authz_core.c>
#     # Apache 2.2
#     Order Deny,Allow
#     Deny from All
#     Allow from 127.0.0.1
#     Allow from ::1
#   </IfModule>
#</Directory>

If you declare a DateTime, then the default value is DateTime.MinValue, and hence you have to check it like this:

DateTime dat = new DateTime();

 if (dat==DateTime.MinValue)
 {
     //unassigned
 }

If the DateTime is nullable, well that's a different story:

 DateTime? dat = null;

 if (!dat.HasValue)
 {
     //unassigned
 }

I faced the same issue. I had missed the forms module import tag in the app.module.ts

import { FormsModule } from '@angular/forms';

@NgModule({
    imports: [BrowserModule,
        FormsModule
    ],

I implement like this:

static createUserWithEmail(String username, String email, String password) async{
    var url = 'http://www.yourbackend.com/'+ "users";
    var body = {
        'user' : {
          'username': username,
          'address': email,
          'password': password
       }
    };

    return http.post(
      url, 
      body: json.encode(body),
      headers: {
        "Content-Type": "application/json"
      },
      encoding: Encoding.getByName("utf-8")
    );
  }

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

If you want to use the version of Javascript called ES 2015 (aka ES6) or later, you can use template strings introduced by ES 2015 and recommended by some guidelines (like Airbnb's style guide):

const after = "test";
const mystr = `This is: ${after}`;

You can access you website using your IP address and your cPanel username with ~ symbols. For Example: http://serverip/~cpusername like as https://xxx.xxx.xx.xx/~mohidul

its happen when you try to delete the same object and then again update the same object use this after delete

session.clear();

This is how I did it and it works:

dictlist = [dict() for x in range(n)]

It gives you a list of n empty dictionaries.

private void Button1_Click(object sender, EventArgs e)
{
    NewForm newForm = new NewForm();    //Create the New Form Object
    this.Hide();    //Hide the Old Form
    newForm.ShowDialog();    //Show the New Form
    this.Close();    //Close the Old Form
}

Like others, the accepted answer also gave me an outdated version.

Here is another way to do it that works very well:

$ curl --silent --location https://rpm.nodesource.com/setup_14.x | bash -
$ yum -y install nodejs

You can also replace the 14.x with another version, such as 12.x, 10.x, etc.

You can see all available versions on the NodeSource Github page, and pull from there as well if desired.

Note: you may need to run using sudo depending on your environment.

Aligning to 6 bytes is not weird, because it is aligning to addresses multiple to 4.

So basically you have 34 bytes in your structure and the next structure should be placed on the address, that is multiple to 4. The closest value after 34 is 36. And this padding area counts into the size of the structure.

I know it's a "very long time" since this question was first asked. Just in case, if it helps someone,

Adding relationships is well supported by MS via SQL Server Compact Tool Box (https://sqlcetoolbox.codeplex.com/). Just install it, then you would get the option to connect to the Compact Database using the Server Explorer Window. Right click on the primary table , select "Table Properties". You should have the following window, which contains "Add Relations" tab allowing you to add relations.

If you use jQuery, u can do it like this:

<form action="example" method="post" id="loginform">
  ...
  <input id="btnin" type="button" value="login"/>
  <input id="btnreg" type="button" value="regist"/>
</form>

And js will be:

$("#btnin").click(function(){
   $("#loginform").attr("action", "user_login");
   $("#loginform").submit();

I can't explain why, but changing url parameter from having localhost to 127.0.0.1 on mongodb.MongoClient.connect() method on Windows 10 solved the issue.

It seems you can provide just the local image name, assuming it is in the same folder...

It suffices like:

background-image: url("img1.png")

To check whether your php.ini file takes effect, open a plain text editor and create a file called phpinfo.php. Insert the following line:

<?php phpinfo(); ?>

Save this file to the root of your Web site and then browse to yourdomain.com/phpinfo.php to test the settings.

Use TextAreaFor

@Html.TextAreaFor(model => model.Description, new { @class = "whatever-class", @cols = 80, @rows = 10 })

or use style for multi-line class.

You could also write EditorTemplate for this.

Apparently --max-depth option is not in Mac OS X's version of the du command. You can use the following instead.

du -h -d 1 | sort -n

You can do it with 2 ways. In template and in Controller. In template you can set your filtered array to another variable, then use it like you want. Here is how to do it:

<ul>
  <li data-ng-repeat="user in usersList = (users | gender:filterGender)" data-ng-bind="user.name"></li>
</ul>
 ....
<span>{{ usersList.length | number }}</span>

If you need examples, see the AngularJs filtered count examples/demos

A mutex is a mutual exclusion object, similar to a semaphore but that only allows one locker at a time and whose ownership restrictions may be more stringent than a semaphore.

It can be thought of as equivalent to a normal counting semaphore (with a count of one) and the requirement that it can only be released by the same thread that locked it^(a).

A semaphore, on the other hand, has an arbitrary count and can be locked by that many lockers concurrently. And it may not have a requirement that it be released by the same thread that claimed it (but, if not, you have to carefully track who currently has responsibility for it, much like allocated memory).

So, if you have a number of instances of a resource (say three tape drives), you could use a semaphore with a count of 3. Note that this doesn't tell you which of those tape drives you have, just that you have a certain number.

Also with semaphores, it's possible for a single locker to lock multiple instances of a resource, such as for a tape-to-tape copy. If you have one resource (say a memory location that you don't want to corrupt), a mutex is more suitable.

Equivalent operations are:

Counting semaphore          Mutual exclusion semaphore
--------------------------  --------------------------
  Claim/decrease (P)                  Lock
  Release/increase (V)                Unlock

Aside: in case you've ever wondered at the bizarre letters used for claiming and releasing semaphores, it's because the inventor was Dutch. Probeer te verlagen means to try and decrease while verhogen means to increase.

^(a) ... or it can be thought of as something totally distinct from a semaphore, which may be safer given their almost-always-different uses.

All non-private instance methods are virtual by default in Java.

In C++, private methods can be virtual. This can be exploited for the non-virtual-interface (NVI) idiom. In Java, you'd need to make the NVI overridable methods protected.

From the Java Language Specification, v3:

8.4.8.1 Overriding (by Instance Methods) An instance method m1 declared in a class C overrides another instance method, m2, declared in class A iff all of the following are true:

1. C is a subclass of A.
2. The signature of m1 is a subsignature (§8.4.2) of the signature of m2.
3. Either * m2 is public, protected or declared with default access in the same package as C, or * m1 overrides a method m3, m3 distinct from m1, m3 distinct from m2, such that m3 overrides m2.

I run into same problem.

What I found from documentation, we should use namedspace.

in your case {% url login:login_view %}

Combining map and struct allow unmarshaling nested JSON objects where the key is dynamic. => map[string]

For example: stock.json

{
  "MU": {
    "symbol": "MU",
    "title": "micro semiconductor",
    "share": 400,
    "purchase_price": 60.5,
    "target_price": 70
  },
  "LSCC":{
    "symbol": "LSCC",
    "title": "lattice semiconductor",
    "share": 200,
    "purchase_price": 20,
    "target_price": 30
  }
}

Go application

package main

import (
    "encoding/json"
    "fmt"
    "io/ioutil"
    "log"
    "os"
)

type Stock struct {
    Symbol        string  `json:"symbol"`
    Title         string  `json:"title"`
    Share         int     `json:"share"`
    PurchasePrice float64 `json:"purchase_price"`
    TargetPrice   float64 `json:"target_price"`
}
type Account map[string]Stock

func main() {
    raw, err := ioutil.ReadFile("stock.json")
    if err != nil {
        fmt.Println(err.Error())
        os.Exit(1)
    }
    var account Account
    log.Println(account)
}

The dynamic key in the hash is handle a string, and the nested object is represented by a struct.

use -fno-objc-arc for each file in build phases

(Edited to improve answer)

First define a function get_latest_file

def get_latest_file(path, *paths):
    fullpath = os.path.join(path, paths)
    ...
get_latest_file('example', 'files','randomtext011.*.txt')

You may also use a docstring !

def get_latest_file(path, *paths):
    """Returns the name of the latest (most recent) file 
    of the joined path(s)"""
    fullpath = os.path.join(path, *paths)

If you use Python 3, you can use iglob instead.

Complete code to return the name of latest file:

def get_latest_file(path, *paths):
    """Returns the name of the latest (most recent) file 
    of the joined path(s)"""
    fullpath = os.path.join(path, *paths)
    files = glob.glob(fullpath)  # You may use iglob in Python3
    if not files:                # I prefer using the negation
        return None                      # because it behaves like a shortcut
    latest_file = max(files, key=os.path.getctime)
    _, filename = os.path.split(latest_file)
    return filename

For versions 2.23 and above only,

Instead of these suggestions, you could use git restore --staged <file> in order to unstage the file(s).

typeperf "\processor(_total)\% processor time"

does work on Win7, you just need to extract the percent value yourself from the last quoted string.

You might find the yes command useful.

This can be an issue with Glide. Use this while you are trying to load to many images and some of them are very large:

Glide.load("your image path")
                       .transform(
                               new MultiTransformation<>(
                                       new CenterCrop(),
                                       new RoundedCorners(
                                               holder.imgCompanyLogo.getResources()
                                                       .getDimensionPixelSize(R.dimen._2sdp)
                                       )
                               )
                       )
                       .error(R.drawable.ic_nfs_default)
                       .into(holder.imgCompanyLogo);
           }

As others have said, @Transient is used to mark fields which shouldn't be persisted. Consider this short example:

public enum Gender { MALE, FEMALE, UNKNOWN }

@Entity
public Person {
    private Gender g;
    private long id;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public Gender getGender() { return g; }    
    public void setGender(Gender g) { this.g = g; }

    @Transient
    public boolean isMale() {
        return Gender.MALE.equals(g);
    }

    @Transient
    public boolean isFemale() {
        return Gender.FEMALE.equals(g);
    }
}

When this class is fed to the JPA, it persists the gender and id but doesn't try to persist the helper boolean methods - without @Transient the underlying system would complain that the Entity class Person is missing setMale() and setFemale() methods and thus wouldn't persist Person at all.

Solved!!

Change Scheme to Microsoft Visual Studio

Store

lastFirstVisiblePosition = ((LinearLayoutManager)rv.getLayoutManager()).findFirstCompletelyVisibleItemPosition();

Restore

((LinearLayoutManager) rv.getLayoutManager()).scrollToPosition(lastFirstVisiblePosition);

and if that doesn't work, try

((LinearLayoutManager) rv.getLayoutManager()).scrollToPositionWithOffset(lastFirstVisiblePosition,0)

Put store in onPause() and restore in onResume()

If you already committed the changes than you would have to revert changes.

If you didn't commit yet, just do a clean checkout git checkout .

In general you add all prerequisite steps to setUp and all clean-up steps to tearDown.

You can read more with examples here.

When a setUp() method is defined, the test runner will run that method prior to each test. Likewise, if a tearDown() method is defined, the test runner will invoke that method after each test.

For example you have a test that requires items to exist, or certain state - so you put these actions(creating object instances, initializing db, preparing rules and so on) into the setUp.

Also as you know each test should stop in the place where it was started - this means that we have to restore app state to it's initial state - e.g close files, connections, removing newly created items, calling transactions callback and so on - all these steps are to be included into the tearDown.

So the idea is that test itself should contain only actions that to be performed on the test object to get the result, while setUp and tearDown are the methods to help you to leave your test code clean and flexible.

You can create a setUp and tearDown for a bunch of tests and define them in a parent class - so it would be easy for you to support such tests and update common preparations and clean ups.

If you are looking for an easy example please use the following link with example

You need $event.currentTarget instead of $event.target.

This is how I delete files

if ((System.IO.File.Exists(fileName)))
                {
                    System.IO.File.Delete(fileName);
}

Also make sure that the file name you are passing in your delete, is the accurate path

EDIT

You could use the following event instead as well or just use the code in this snippet and use in your method

void GridView1_SelectedIndexChanged(Object sender, EventArgs e)
  {

    // Get the currently selected row using the SelectedRow property.
    GridViewRow row = CustomersGridView.SelectedRow;

    //Debug this line and see what value is returned if it contains the full path.
    //If it does not contain the full path then add the path to the string.
    string fileName = row.Cells[0].Text 

    if(fileName != null || fileName != string.empty)
    {
       if((System.IO.File.Exists(fileName))
           System.IO.File.Delete(fileName);

     }
  }

Don't have enough reputation to comment yet. Using Ubuntu and a simple:

sudo apt-get install php5-curl
sudo /etc/init.d/apache2 restart

Did NOT work for me.

For some reason curl.so was installed in a location not picked up by default. I checked the extension_dir in my php.ini and copied over the curl.so to my extension_dir

cp /usr/lib/php5/20090626/curl.so  /usr/local/lib/php/extensions/no-debug-non-zts-20090626

Hope this helps someone, adjust your path locations accordingly.

There is an alternative approach, which does not have I18n problems (allowing ',' or '.' but not both): Decimal.TryParse.

Just try converting, ignoring the value.

bool IsDecimalFormat(string input) {
  Decimal dummy;
  return Decimal.TryParse(input, out dummy);
}

This is significantly faster than using a regular expression, see below.

(The overload of Decimal.TryParse can be used for finer control.)

Performance test results: Decimal.TryParse: 0.10277ms, Regex: 0.49143ms

Code (PerformanceHelper.Run is a helper than runs the delegate for passed iteration count and returns the average TimeSpan.):

    };

    static void Main(string[] args) {
        Action parser = () => {
            int n = TestData.Length;
            int count = 0;
            for (int i = 0; i < n; ++i) {
                decimal dummy;
                count += Decimal.TryParse(TestData[i], out dummy) ? 1 : 0;
            }
        };
        Regex decimalRegex = new Regex(@"^[0-9]([\.\,][0-9]{1,3})?$");
        Action regex = () => {
            int n = TestData.Length;
            int count = 0;
            for (int i = 0; i < n; ++i) {
                count += decimalRegex.IsMatch(TestData[i]) ? 1 : 0;
            }
        };

        var paserTotal = 0.0;
        var regexTotal = 0.0;
        var runCount = 10;
        for (int run = 1; run <= runCount; ++run) {
            var parserTime = PerformanceHelper.Run(10000, parser);
            var regexTime = PerformanceHelper.Run(10000, regex);

            Console.WriteLine("Run #{2}: Decimal.TryParse: {0}ms, Regex: {1}ms",
                              parserTime.TotalMilliseconds, 
                              regexTime.TotalMilliseconds,
                              run);
            paserTotal += parserTime.TotalMilliseconds;
            regexTotal += regexTime.TotalMilliseconds;
        }

        Console.WriteLine("Overall averages: Decimal.TryParse: {0}ms, Regex: {1}ms",
                          paserTotal/runCount,

I know this question is old, and already answered, but...

Since SqlDataReader already implements IEnumerable, why is there a need to create a loop over the records?

I've been using the method below without any issues, nor without any performance issues: So far I have tested with IList, List(Of T), IEnumerable, IEnumerable(Of T), IQueryable, and IQueryable(Of T)

I faced the same problem about 2 days ago when I had to convert a 20GB+ MySQL database to SQLite. It was by no means an easy task and I ended up writing this Python package that does the job.

The upside of it being written in Python is that it's cross platform (unlike a shell/bash script) and can all be easily installed using pip install (even on Windows). It uses generators and chunking of the data being processed and is therefore very memory efficient.

I also put in some effort to correctly translate most of the datatypes from MySQL to SQLite.

The tool is also thoroughly tested and works on Python 2.7 and 3.5+.

It is invokable via command line but can also be used as a standard Python class which you can include in some larger Python orchestration.

Here's how you use it:

Usage: mysql2sqlite [OPTIONS]

Options:
  -f, --sqlite-file PATH     SQLite3 database file  [required]
  -d, --mysql-database TEXT  MySQL database name  [required]
  -u, --mysql-user TEXT      MySQL user  [required]
  -p, --mysql-password TEXT  MySQL password
  -h, --mysql-host TEXT      MySQL host. Defaults to localhost.
  -P, --mysql-port INTEGER   MySQL port. Defaults to 3306.
  -c, --chunk INTEGER        Chunk reading/writing SQL records
  -l, --log-file PATH        Log file
  -V, --vacuum               Use the VACUUM command to rebuild the SQLite
                             database file, repacking it into a minimal amount
                             of disk space
  --use-buffered-cursors     Use MySQLCursorBuffered for reading the MySQL
                             database. This can be useful in situations where
                             multiple queries, with small result sets, need to
                             be combined or computed with each other.
  --help                     Show this message and exit.

Python 3.6+:

coordinates = [('a',1,2), ('b',3,4), ('c',5,6)]
for x in coordinates: plt.annotate(x[0], (x[1], x[2]))

summation and your other functions are defined after they're used in main, and so the compiler has made a guess about it's signature; in other words, an implicit declaration has been assumed.

You should declare the function before it's used and get rid of the warning. In the C99 specification, this is an error.

Either move the function bodies before main, or include method signatures before main, e.g.:

#include <stdio.h>

int summation(int *, int *, int *);

int main()
{
    // ...

Seems like you could use date() and the lowercase "L" format character in the following way:

$weekday_name = date("l", $timestamp);

Works well for me, here is the doc: http://php.net/manual/en/function.date.php

My recommendation is to save the data to database with Line breaks instead parsing it with nl2br. You should use nl2br in output not input.

For your question, you can use php or javascript:

PHP:

str_replace('<br />', "\n", $textarea);

jQuery:

$('#myTextArea').val($('#myTextArea').val().replace(@<br />@, "\N"));

In C++11, there are actually std::to_string and std::to_wstring functions in <string>.

string to_string(int val);
string to_string(long val);
string to_string(long long val);
string to_string(unsigned val);
string to_string(unsigned long val);
string to_string(unsigned long long val);
string to_string(float val);
string to_string(double val);
string to_string (long double val);

If you're not using the less version, here is the line you need to change:

@media (max-width: 767px) { /* Change this to 0 */
  .navbar-nav .open .dropdown-menu {
    position: static;
    float: none;
    width: auto;
    margin-top: 0;
    background-color: transparent;
    border: 0;
    box-shadow: none;
  }
  .navbar-nav .open .dropdown-menu > li > a,
  .navbar-nav .open .dropdown-menu .dropdown-header {
    padding: 5px 15px 5px 25px;
  }
  .navbar-nav .open .dropdown-menu > li > a {
    line-height: 20px;
  }
  .navbar-nav .open .dropdown-menu > li > a:hover,
  .navbar-nav .open .dropdown-menu > li > a:focus {
    background-image: none;
  }
}

I used IBOutlets in my project. So my solution was:

@IBOutlet weak var addBarButton: UIBarButtonItem!

addBarButton.enabled = false
addBarButton.tintColor = UIColor.clearColor()

And when you'll need to show this bar again, just set reversed properties.

In Swift 3 instead enable use isEnable property.

In Bjarne Stroustrup's C++ programming language book, you can read that he's proposing to overload the operator++ for your specific enum. enum are user-defined types and overloading operator exists in the language for these specific situations.

You'll be able to code the following:

#include <iostream>
enum class Colors{red, green, blue};
Colors& operator++(Colors &c, int)
{
     switch(c)
     {
           case Colors::red:
               return c=Colors::green;
           case Colors::green:
               return c=Colors::blue;
           case Colors::blue:
               return c=Colors::red; // managing overflow
           default:
               throw std::exception(); // or do anything else to manage the error...
     }
}

int main()
{
    Colors c = Colors::red;
    // casting in int just for convenience of output. 
    std::cout << (int)c++ << std::endl;
    std::cout << (int)c++ << std::endl;
    std::cout << (int)c++ << std::endl;
    std::cout << (int)c++ << std::endl;
    std::cout << (int)c++ << std::endl;
    return 0;
}

test code: http://cpp.sh/357gb

Mind that I'm using enum class. Code works fine with enum also. But I prefer enum class since they are strong typed and can prevent us to make mistake at compile time.

I kept getting the following error when I tried to start mongodb.

"shutting down with code:100" 

I was using the following command:

./mongod --dbpath=~/mongo-data

The fix for me was that I didn't need the "=" sign and this was causing the error. So I did

./mongod --dbpath ~/mongo-data

Just wanted to throw this out there because the error in no way specifies that this is the problem. I almost removed the contents of the ~/mongo-data directory to see if that helped. Glad I remembered that cli args sometimes do not use the "=" sign.

The read(1) utility along with output redirection of the ls(1) command will do what you want.

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

Oddly enough it was an Intel thing not a Microsoft thing. X86 referred to the Intel CPU series from the 8086 to the 80486. The Pentium series still use the same addressing system. The x64 refers to the I64 addressing system that Intel came out with later for the 64-bit CPUs. So Windows was just following Intel's architecture naming.

concerning Readability:

I typically prefer if/else constructs over switch statements, especially in languages that allows fall-through cases. What I've found, often, is as the projects age, and multiple developers gets involved, you'll start having trouble with the construction of a switch statement.

If they (the statements) become anything more than simple, many programmers become lazy and instead of reading the entire statement to understand it, they'll simply pop in a case to cover whatever case they're adding into the statement.

I've seen many cases where code repeats in a switch statement because a person's test was already covered, a simple fall-though case would have sufficed, but laziness forced them to add the redundant code at the end instead of trying to understand the switch. I've also seen some nightmarish switch statements with many cases that were poorly constructed, and simply trying to follow all the logic, with many fall-through cases dispersed throughout, and many cases which weren't, becomes difficult ... which kind of leads to the first/redundancy problem I talked about.

Theoretically, the same problem could exist with if/else constructs, but in practice this just doesn't seem to happen as often. Maybe (just a guess) programmers are forced to read a bit more carefully because you need to understand the, often, more complex conditions being tested within the if/else construct? If you're writing something simple that you know others are likely to never touch, and you can construct it well, then I guess it's a toss-up. In that case, whatever is more readable and feels best to you is probably the right answer because you're likely to be sustaining that code.

concerning Speed:

Switch statements often perform faster than if-else constructs (but not always). Since the possible values of a switch statement are laid out beforehand, compilers are able to optimize performance by constructing jump tables. Each condition doesn't have to be tested as in an if/else construct (well, until you find the right one, anyway).

However this isn't always the case, though. If you have a simple switch, say, with possible values of 1 to 10, this will be the case. The more values you add requires the jump tables to be larger and the switch becomes less efficient (not than an if/else, but less efficient than the comparatively simple switch statement). Also, if the values are highly variant ( i.e. instead of 1 to 10, you have 10 possible values of, say, 1, 1000, 10000, 100000, and so on to 100000000000), the switch is less efficient than in the simpler case.

Hope this helps.

First, have you compiled the class using the command line javac compiler? Second, it seems that your main method has an incorrect signature - it should be taking in an array of String objects, rather than just one:

public static void main(String[] args){

Once you've changed your code to take in an array of String objects, then you need to make sure that you're printing an element of the array, rather than array itself:

System.out.println(args[0])

If you want to print the whole list of command line arguments, you'd need to use a loop, e.g.

for(int i = 0; i < args.length; i++){
    System.out.print(args[i]);
}
System.out.println();

If you wish to list all tables, you must use:

\dt *.*

to indicate that you want all tables in all schemas. This will include tables in pg_catalog, the system tables, and those in information_schema. There's no built-in way to say "all tables in all user-defined schemas"; you can, however, set your search_path to a list of all schemas of interest before running \dt.

You may want to do this programmatically, in which case psql backslash-commands won't do the job. This is where the INFORMATION_SCHEMA comes to the rescue. To list tables:

SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';

BTW, if you ever want to see what psql is doing in response to a backslash command, run psql with the -E flag. eg:

$ psql -E regress    
regress=# \list
********* QUERY **********
SELECT d.datname as "Name",
       pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
       pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
       d.datcollate as "Collate",
       d.datctype as "Ctype",
       pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;
**************************

so you can see that psql is searching pg_catalog.pg_database when it gets a list of databases. Similarly, for tables within a given database:

SELECT n.nspname as "Schema",
  c.relname as "Name",
  CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i' THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' WHEN 'f' THEN 'foreign table' END as "Type",
  pg_catalog.pg_get_userbyid(c.relowner) as "Owner"
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
      AND n.nspname <> 'pg_catalog'
      AND n.nspname <> 'information_schema'
      AND n.nspname !~ '^pg_toast'
  AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;

It's preferable to use the SQL-standard, portable INFORMATION_SCHEMA instead of the Pg system catalogs where possible, but sometimes you need Pg-specific information. In those cases it's fine to query the system catalogs directly, and psql -E can be a helpful guide for how to do so.

The other answers gave me the right clues, but they didn't completely help.

Here's what worked for me:

$ git checkout email
$ git tag old-email-branch # This is optional
$ git reset --hard staging
$
$ # Using a custom commit message for the merge below
$ git merge -m 'Merge -s our where _ours_ is the branch staging' -s ours origin/email
$ git push origin email

Without the fourth step of merging with the ours strategy, the push is considered a non-fast-forward update and will be rejected (by GitHub).

Below is the easiest way to SSh in java. Download any of the file in the below link and extract, then add the jar file from the extracted file and add to your build path of the project http://www.ganymed.ethz.ch/ssh2/ and use the below method

public void SSHClient(String serverIp,String command, String usernameString,String password) throws IOException{
        System.out.println("inside the ssh function");
        try
        {
            Connection conn = new Connection(serverIp);
            conn.connect();
            boolean isAuthenticated = conn.authenticateWithPassword(usernameString, password);
            if (isAuthenticated == false)
                throw new IOException("Authentication failed.");        
            ch.ethz.ssh2.Session sess = conn.openSession();
            sess.execCommand(command);  
            InputStream stdout = new StreamGobbler(sess.getStdout());
            BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
            System.out.println("the output of the command is");
            while (true)
            {
                String line = br.readLine();
                if (line == null)
                    break;
                System.out.println(line);
            }
            System.out.println("ExitCode: " + sess.getExitStatus());
            sess.close();
            conn.close();
        }
        catch (IOException e)
        {
            e.printStackTrace(System.err);

        }
    }

I've never come across point 2? Can you explain why you think this affects deployment in any way. If anything maven allows you to structure your projects in a modularised way that actually allows hot fixes for bugs in a particular tier, and allows independent development of an API from the remainder of the project for example.

It is possible that you are trying to cram everything into a single module, in which case the problem isn't really maven at all, but the way you are using it.

This is a bit of an old post, but there is actually a way to do an onclick operator that calls a function instead of going anywhere in ASP.NET

helper.ActionLink("Choose", null, null, null, 
    new {@onclick = "Locations.Choose(" + location.Id + ")", @href="#"})

If you specify empty quotes or the like in the controller/action, it'll likely add a link to what you listed. You can do that, and do a return false in the onclick. You can read more about that at:

What's the effect of adding 'return false' to a click event listener?

If you're doing this onclick in an cshtml file, it'd be a bit cleaner to just specify the link yourself (a href...) instead of having the ActionLink handle it. If you're doing an HtmlHelper, like my example above is coming from, then I'd argue that calling ActionLink is an okay solution, or potentially better, is to use tagbuilder instead.

Use the Activity Monitor. It's the last toolbar in the top bar. It will show you a list of "Recent Expensive Queries". You can double-click them to see the execution plan, etc.

BATCH LOAD - OK, so after having my previous reply deleted for just using links I have updated with the code I managed to get working. Appreciate anyone to simplify / correct / refine / put in function etc as I'm still learning this stuff, but I got batch member list add working :)

You can easily create your own serializer

var car = new Car() { Name = "Ford", Owner = "John Smith" };
string json = Serialize(car);

string Serialize<T>(T o)
{
    var attr = o.GetType().GetCustomAttribute(typeof(JsonObjectAttribute)) as JsonObjectAttribute;

    var jv = JValue.FromObject(o);

    return new JObject(new JProperty(attr.Title, jv)).ToString();
}

from FOLDER_NAME import FILENAME
from FILENAME import CLASS_NAME FUNCTION_NAME

FILENAME is w/o the suffix

Usually when I want to pass arguments to an alias in Bash, I use a combination of an alias and a function like this, for instance:

function __t2d {                                                                
         if [ "$1x" != 'x' ]; then                                              
            date -d "@$1"                                                       
         fi                                                                     
} 

alias t2d='__t2d'                                                               

After reading Paul's answer, I went on digging for more information on https://dev.mysql.com/doc/refman/5.7/en/query-log.html

I found a really useful code by a person. Here's the summary of the context.

(Note: The following code is not mine)

This script is an example to keep the table clean which will help you to reduce your table size. As after a day, there will be about 180k queries of log. ( in a file, it would be 30MB per day)

You need to add an additional column (event_unix) and then you can use this script to keep the log clean... it will update the timestamp into a Unix-timestamp, delete the logs older than 1 day and then update the event_time into Timestamp from event_unix... sounds a bit confusing, but it's working great.

Commands for the new column:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
ALTER TABLE `general_log_temp`
ADD COLUMN `event_unix` int(10) NOT NULL AFTER `event_time`;
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Cleanup script:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
UPDATE general_log_temp SET event_unix = UNIX_TIMESTAMP(event_time);
DELETE FROM `general_log_temp` WHERE `event_unix` < UNIX_TIMESTAMP(NOW()) - 86400;
UPDATE general_log_temp SET event_time = FROM_UNIXTIME(event_unix);
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Credit goes to Sebastian Kaiser (Original writer of the code).

Hope someone will find it useful as I did.

Here is an async helper function written in typescript that seems to do the trick for me. I guess this will not work for long-lived processes but still might be handy for someone?

import * as child_process from "child_process";

private async spawn(command: string, args: string[]): Promise<{code: number | null, result: string}> {
    return new Promise((resolve, reject) => {
        const spawn = child_process.spawn(command, args)
        let result: string

import os
os.path.abspath(os.path.expanduser(os.path.expandvars(PathNameString)))

Note that expanduser is necessary (on Unix) in case the given expression for the file (or directory) name and location may contain a leading ~/(the tilde refers to the user's home directory), and expandvars takes care of any other environment variables (like $HOME).

Downcasting is allowed when there is a possibility that it succeeds at run time:

Object o = getSomeObject(),
String s = (String) o; // this is allowed because o could reference a String

In some cases this will not succeed:

Object o = new Object();
String s = (String) o; // this will fail at runtime, because o doesn't reference a String

When a cast (such as this last one) fails at runtime a ClassCastException will be thrown.

In other cases it will work:

Object o = "a String";
String s = (String) o; // this will work, since o references a String

Note that some casts will be disallowed at compile time, because they will never succeed at all:

Integer i = getSomeInteger();
String s = (String) i; // the compiler will not allow this, since i can never reference a String.

This should work

if(!Directory.Exists(@"C:\MP_Upload")) {
    Directory.CreateDirectory(@"C:\MP_Upload");
}

I wrote a javascript url parsing library, URL.js, you can use it for this.

Example:

url.parse("http://mysite.com/form_image_edit.php?img_id=33").get.img_id === "33"

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

In file included from ../../shogun/features/SubsetStack.h:14:0, 
                 from ../../shogun/features/Features.h:21,

You can use \r to go to next line while filling up the UILabel using NSString.

UILabel * label;


label.text = [NSString stringWithFormat:@"%@ \r %@",@"first line",@"seconcd line"];

Old thread but I had the same problem now. If anyone encounters this he'll probably find this answer:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
yourImageView.setLayoutParams(layoutParams);

This will work only if you add the ImageView as a subView to a LinearLayout. If you add it to a RelativeLayout you will need to call:

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(30, 30);
yourImageView.setLayoutParams(layoutParams);

I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.

In short: if you are inputting a string array of length t, then Scanner#nextLine() expects t lines, each entry in the string array is differentiated from the other by enter key.And Scanner#next() will keep taking inputs till you press enter but stores string(word) inside the array, which is separated by whitespace.

Lets have a look at following snippet of code

    Scanner in = new Scanner(System.in);
    int t = in.nextInt();
    String[] s = new String[t];

    for (int i = 0; i < t; i++) {
        s[i] = in.next();
    }

when I run above snippet of code in my IDE (lets say for string length 2),it does not matter whether I enter my string as

Input as :- abcd abcd or

Input as :-

abcd

abcd

Output will be like abcd

abcd

But if in same code we replace next() method by nextLine()

    Scanner in = new Scanner(System.in);
    int t = in.nextInt();
    String[] s = new String[t];

    for (int i = 0; i < t; i++) {
        s[i] = in.nextLine();
    }

Then if you enter input on prompt as - abcd abcd

Output is :-

abcd abcd

and if you enter the input on prompt as abcd (and if you press enter to enter next abcd in another line, the input prompt will just exit and you will get the output)

Output is:-

abcd

Just do the following change

echo off
cls

echo Would you like to do a backup?

pause

copy "\\My_Servers_IP\Shared Drive\FolderName\*" C:\TEST_BACKUP_FOLDER

pause

As of May 2018, it seems that a workspace in Visual Studio Code allows you to have quick access to different but related projects. All without having to open a different folder.

And you can have multiple workspaces too. See references here and you will get the full picture of it:

Reference 1
Reference 2

document.forms[ 'forms1' ].onsubmit = function() {
    return [].some.call( this.elements, function( el ) {
        return el.type === 'radio' ? el.checked : false
    } )
}

Just something out of my head. Not sure the code is working.

Try:

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

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

You can see Logic functions for more details.

In the html file:

<input type="text" placeholder="placeholder" class="redPlaceHolder">

In the css file:

.redPlaceHolder{
   color: #ff0000;
}

abs function is definitely not what you need as it is not calculating the distance. Try abs (-25+15) to see that it's not working. A distance between the numbers is 40 but the output will be 10. Because it's doing the math and then removing "minus" in front. I am using this custom function:

def distance(a, b):
    if (a < 0) and (b < 0) or (a > 0) and (b > 0):
        return abs( abs(a) - abs(b) )
    if (a < 0) and (b > 0) or (a > 0) and (b < 0):
        return abs( abs(a) + abs(b) )

print distance(-25, -15)
print distance(25, -15)
print distance(-25, 15)
print distance(25, 15)

Extending Rosário Pereira Fernandes' answer, for a JavaScript solution:

1. Install firebase on your machine

npm install -g firebase-tools

2. On firebase init set JavaScript as default language
3. On the root folder of created project execute npm installs

   npm install --save firebase
   npm install @google-cloud/storage
   npm install @google-cloud/firestore
   ... <any other dependency needed>

4. Add non-default dependencies on your project like

    "firebase": "^6.3.3",
    "@google-cloud/storage": "^3.0.3"

functions/package.json

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "10"
  },
  "dependencies": {
    "@google-cloud/storage": "^3.0.3",
    "firebase": "^6.3.3",
    "firebase-admin": "^8.0.0",
    "firebase-functions": "^3.1.0"
  },
  "devDependencies": {
    "eslint": "^5.12.0",
    "eslint-plugin-promise": "^4.0.1",
    "firebase-functions-test": "^0.1.6"
  },
  "private": true
}

5. Create sort of a listAll function

index.js

var serviceAccount = require("./key.json");
const functions = require('firebase-functions');

const images = require('./images.js');

var admin = require("firebase-admin");

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://<my_project>.firebaseio.com"
});

const bucket = admin.storage().bucket('<my_bucket>.appspot.com')

exports.getImages = functions.https.onRequest((request, response) => {
    images.getImages(bucket)
        .then(urls => response.status(200).send({ data: { urls } }))
        .catch(err => console.error(err));
})

images.js

module.exports = {
    getImages
}

const query = {
    directory: 'images'
};

function getImages(bucket) {
    return bucket.getFiles(query)
        .then(response => getUrls(response))
        .catch(err => console.error(err));
}

function getUrls(response) {
    const promises = []
    response.forEach( files => {
        files.forEach (file => {
            promises.push(getSignedUrl(file));
        });
    });
    return Promise.all(promises).then(result => getParsedUrls(result));
}

function getSignedUrl(file) {
    return file.getSignedUrl({
        action: 'read',
        expires: '09-01-2019'
    })
}

function getParsedUrls(result) {
    return JSON.stringify(result.map(mediaLink => createMedia(mediaLink)));
}

function createMedia(mediaLink) {
    const reference = {};
    reference.mediaLink = mediaLink[0];
    return reference;
}

6. Execute firebase deploy to upload your cloud function
7. Call your custom function from your app

build.gradle

dependencies {
...
  implementation 'com.google.firebase:firebase-functions:18.1.0'
...
}

kotlin class

  private val functions = FirebaseFunctions.getInstance()
  val cloudFunction = functions.getHttpsCallable("getImages")
  cloudFunction.call().addOnSuccessListener {...}

Regarding the further development of this feature, I ran into some problems that might found here.

The expires and add_header directives have no impact on NGINX caching the files, those are purely about what the browser sees.

What you likely want instead is:

location stuffyoudontwanttocache {
    # don't cache it
    proxy_no_cache 1;
    # even if cached, don't try to use it
    proxy_cache_bypass 1; 
}

Though usually .js etc is the thing you would cache, so perhaps you should just disable caching entirely?

you must put at least a capture () in the pattern to match, and correct pattern like this:

String[] words = {"{apf","hum_","dkoe","12f"};
for(String s:words)
{
    if(s.matches("(^[a-z]+$)"))
    {
        System.out.println(s);
    }
}

In Java, once you have the reference of the button:

Button button = (Button) findviewById(R.id.button);

To enable/disable the button, you can use either:

button.setEnabled(false);
button.setEnabled(true);

Or:

button.setClickable(false);
button.setClickable(true);

Since you want to disable the button from the beginning, you can use button.setEnabled(false); in the onCreate method. Otherwise, from XML, you can directly use:

android:clickable = "false"

So:

<Button
        android:id="@+id/button"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="@string/button_text"
        android:clickable = "false" />

This one works for me. The --no-color part is, or can be, important if you want a plain string back.

git branch --no-color | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'

Well you could directly substract from the value by just referencing the key. Which in my opinion is simpler.

>>> books = {}
>>> books['book'] = 3       
>>> books['book'] -= 1   
>>> books   
{'book': 2}   

In your case:

book_shop[ch1] -= 1

Since Python 3.5 you can unpack unlimited amount of lists.

PEP 448 - Additional Unpacking Generalizations

So this will work:

a = ['1', '2', '3', '4']
b = ['5', '6']
function_that_needs_strings(*a, *b)

On iOS, it currently does not matter if you use int or NSInteger. It will matter more if/when iOS moves to 64-bits.

Simply put, NSIntegers are ints in 32-bit code (and thus 32-bit long) and longs on 64-bit code (longs in 64-bit code are 64-bit wide, but 32-bit in 32-bit code). The most likely reason for using NSInteger instead of long is to not break existing 32-bit code (which uses ints).

CGFloat has the same issue: on 32-bit (at least on OS X), it's float; on 64-bit, it's double.

Update: With the introduction of the iPhone 5s, iPad Air, iPad Mini with Retina, and iOS 7, you can now build 64-bit code on iOS.

Update 2: Also, using NSIntegers helps with Swift code interoperability.

In the case you copy your public key with clipboard and paste it, it may happen the public key string can be broken which contains new-line.

Make sure your public key string formed as one line.

Given a parent class named Parent and a child class named Child, you can do something like this:

class Parent {
public:
    virtual void print(int x);
};

class Child : public Parent {
    void print(int x) override;
};

void Parent::print(int x) {
    // some default behavior
}

void Child::print(int x) {
    // use Parent's print method; implicitly passes 'this' to Parent::print
    Parent::print(x);
}

Note that Parent is the class's actual name and not a keyword.

The answers above are correct, but I thought I would expand another answer by offering a way to do the same if you require to pass parameters into the query.

The SqlDataAdapter is quick and simple, but only works if you're filling a table with a static request ie: a simple SELECT without parameters.

Here is my way to do the same, but using a parameter to control the data I require in my table. And I use it to populate a DropDownList.

//populate the Programs dropdownlist according to the student's study year / preference
DropDownList ddlPrograms = (DropDownList)DetailsView1.FindControl("ddlPrograms");
if (ddlPrograms != null)
{
    using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ATCNTV1ConnectionString"].ConnectionString))
    {
        try
        {
            con.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = con;
            cmd.CommandText = "SELECT ProgramID, ProgramName FROM tblPrograms WHERE ProgramCatID > 0 AND ProgramStatusID = (CASE WHEN @StudyYearID = 'VPR' THEN 10 ELSE 7 END) AND ProgramID NOT IN (23,112,113) ORDER BY ProgramName";
            cmd.Parameters.Add("@StudyYearID", SqlDbType.Char).Value = "11";
            DataTable wsPrograms = new DataTable();
            wsPrograms.Load(cmd.ExecuteReader());

            //populate the Programs ddl list
            ddlPrograms.DataSource = wsPrograms;
            ddlPrograms.DataTextField = "ProgramName";
            ddlPrograms.DataValueField = "ProgramID";
            ddlPrograms.DataBind();
            ddlPrograms.Items.Insert(0, new ListItem("<Select Program>", "0"));
        }
        catch (Exception ex)
        {
            // Handle the error
        }
    }
}

Enjoy

If you want to original values to be appear in ticks use

plt.xticks(ticks=plt.xticks()[0], labels=plt.xticks()[0])

This will prevent abbreviations like from 3000000 to 1.3 e5 etc. and will show 3000000 (the exact value) in ticks.

as_json

You should use as_json method which converts ActiveRecord objects to Ruby Hashes despite its name

tasks_records = TaskStoreStatus.all
tasks_records = tasks_records.as_json

# You can now add new records and return the result as json by calling `to_json`

tasks_records << TaskStoreStatus.last.as_json
tasks_records << { :task_id => 10, :store_name => "Koramanagala", :store_region => "India" }
tasks_records.to_json

serializable_hash

You can also convert any ActiveRecord objects to a Hash with serializable_hash and you can convert any ActiveRecord results to an Array with to_a, so for your example :

tasks_records = TaskStoreStatus.all
tasks_records.to_a.map(&:serializable_hash)

And if you want an ugly solution for Rails prior to v2.3

JSON.parse(tasks_records.to_json) # please don't do it

I found this question by the title. If anyone else is looking for the answer on how to just get the domain name, use the following environment variable.

System.Environment.UserDomainName

I'm aware that the author to the question mentions this, but I missed it at the first glance and thought someone else might do the same.

What the description of the question then ask for is the fully qualified domain name (FQDN).

The AHK script is a great idea. Just for those interested I needed to change it a little bit to work for me:

SetTitleMatchMode,2         ;;; allows for a partial search 
#IfWinActive, .py           ;;; scope limiter to only python files
:b*:print ::print(){Left}   ;;; I forget what b* does
#IfWinActive                ;;; remove the scope limitation

I would just do

var list = new List<string> { "hello" };

Maybe that's a bit shorter and easier to understand:

import re
text = '... someline abc... someother line... name my_user_name is valid.. some more lines'
>>> re.search('name (.*) is valid', text).group(1)
'my_user_name'

Try using varchar2 instead of varchar and use this :

INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');

It really does not make sense to shift both into the positive, if you want a growth value that is comparable with the normal growth as result of both positive numbers. If I want to see the growth of 2 positive numbers, I don't want the shifting.

It makes however sense to invert the growth for 2 negative numbers. -1 to -2 is mathematically a growth of 100%, but that feels as something positive, and in fact, the result is a decline.

So, I have following function, allowing to invert the growth for 2 negative numbers:

setGrowth(Quantity q1, Quantity q2, boolean fromPositiveBase) {
if (q1.getValue().equals(q2.getValue()))
    setValue(0.0F);
else if (q1.getValue() <= 0 ^ q2.getValue() <= 0) // growth makes no sense
    setNaN();
else if (q1.getValue() < 0 && q2.getValue() < 0) // both negative, option to invert
    setValue((q2.getValue() - q1.getValue()) / ((fromPositiveBase? -1: 1) * q1.getValue()));
else // both positive
    setValue((q2.getValue() - q1.getValue()) / q1.getValue());
}

The best way to remember this is that the order of for loop inside the list comprehension is based on the order in which they appear in traditional loop approach. Outer most loop comes first, and then the inner loops subsequently.

So, the equivalent list comprehension would be:

[entry for tag in tags for entry in entries if tag in entry]

In general, if-else statement comes before the first for loop, and if you have just an if statement, it will come at the end. For e.g, if you would like to add an empty list, if tag is not in entry, you would do it like this:

[entry if tag in entry else [] for tag in tags for entry in entries]

What about 1.1E10, +1, -0, etc? Parsing all possible numbers is trickier than many people think. If you want to include as many numbers are possible you should use the to_number function in a PL/SQL function. From http://www.oracle-developer.net/content/utilities/is_number.sql:

CREATE OR REPLACE FUNCTION is_number (str_in IN VARCHAR2) RETURN NUMBER IS
   n NUMBER;
BEGIN
   n := TO_NUMBER(str_in);
   RETURN 1;
EXCEPTION
   WHEN VALUE_ERROR THEN
      RETURN 0;
END;

You could use TimeZoneInfo class

The TimeZone class recognizes local time zone, and can convert times between Coordinated Universal Time (UTC) and local time. A TimeZoneInfo object can represent any time zone, and methods of the TimeZoneInfo class can be used to convert the time in one time zone to the corresponding time in any other time zone. The members of the TimeZoneInfo class support the following operations:

1. Retrieving a time zone that is already defined by the operating system.

2. Enumerating the time zones that are available on a system.

3. Converting times between different time zones.

4. Creating a new time zone that is not already defined by the operating system.

   Serializing a time zone for later retrieval.

like some say boost::replace_all

here a dummy example:

    #include <boost/algorithm/string/replace.hpp>

    std::string path("file.gz");
    boost::replace_all(path, ".gz", ".zip");

You can use the < !-- [if IE] > hack to set a global js variable that then gets tested in your normal js code. A bit ugly but has worked well for me.

To update the content of existing rows use the UPDATE statement:

UPDATE table_name SET table_column = 'test';

without using the System.arraycopy method you can delete an element from an array with the following

    int i = 0;
    int x = 0;
    while(i < oldArray.length){
        if(oldArray[i] == 3)i++;

        intArray[x] = oldArray[i];
        i++;
        x++;
    }

where 3 is the value you want to remove.

The below css code always keep the button at the bottom of the page

position:absolute;
bottom:0;

Since you want to do it in relative positioning, you should go for margin-top:100%

position:relative;
margin-top:100%;

EDIT1: JSFiddle1

EDIT2: To place button at center of the screen,

position:relative;
left: 50%;
margin-top:50%;

JSFiddle2

In Linux I resolve this problem by going to the root command prompt type:

# mysqladmin -u root password 'Secret Phrase Here'

Then go back and login. Works every time!

CSS Only:

Thinking about it on my way to the supermarket, you could of course also skip the entire image map idea, and make use of :hover on the elements on top of the image (changed the divs to a-blocks). Which makes things hell of a lot simpler, no jQuery needed...

Short explanation:

• Image is in the bottom
• 2 x a with display:block and absolute positioning + opacity:0
• Set opacity to 0.2 on hover

Example:

.area {_x000D_
    background:#fff;_x000D_
    display:block;_x000D_
    height:475px;_x000D_
    opacity:0;_x000D_
    position:absolute;_x000D_
    width:320px;_x000D_
}_x000D_
#area2 {_x000D_
    left:320px;_x000D_
}_x000D_
#area1:hover, #area2:hover {_x000D_
    opacity:0.2;_x000D_
}

Original Answer using jQuery

I just created something similar with jQuery, I don't think it can be done with CSS only.

Short explanation:

• Image is in the bottom
• Divs with rollover (image or color) with absolute positioning + display:none
• Transparent gif with the actual #map is on top (absolute position) (to prevent call to mouseout when the rollovers appear)
• jQuery is used to show/hide the divs

    $(document).ready(function() {_x000D_
        if($('#location-map')) {_x000D_

By default, *.sh files are opened in a text editor (Xcode or TextEdit). To create a shell script that will execute in Terminal when you open it, name it with the “command” extension, e.g., file.command. By default, these are sent to Terminal, which will execute the file as a shell script.

You will also need to ensure the file is executable, e.g.:

chmod +x file.command

Without this, Terminal will refuse to execute it.

Note that the script does not have to begin with a #! prefix in this specific scenario, because Terminal specifically arranges to execute it with your default shell. (Of course, you can add a #! line if you want to customize which shell is used or if you want to ensure that you can execute it from the command line while using a different shell.)

Also note that Terminal executes the shell script without changing the working directory. You’ll need to begin your script with a cd command if you actually need it to run with a particular working directory.

If anyone else that finds this question and needs a dynamic solution for this where you have an undefined number of columns to transpose to and not exactly 3, you can find a nice solution here: https://github.com/jumpstarter-io/colpivot

or an alternative is the following (using document object)

parent.document.location.href = "http://example.com";

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

sudo apt-get install openjfx

yourValue.ToString("0.00") will work.

There are 2 ways to obfuscate python scripts

• Obfuscate byte code of each code object
• Obfuscate whole code object of python module

Obfuscate Python Scripts

• Compile python source file to code object

  char * filename = "xxx.py";
  char * source = read_file( filename );
  PyObject *co = Py_CompileString( source, filename, Py_file_input );
  

• Iterate code object, wrap bytecode of each code object as the following format

  0   JUMP_ABSOLUTE            n = 3 + len(bytecode)    
  3
  ...
  ... Here it's obfuscated bytecode
  ...
  
  n   LOAD_GLOBAL              ? (__armor__)
  n+3 CALL_FUNCTION            0
  n+6 POP_TOP
  n+7 JUMP_ABSOLUTE            0
  

• Serialize code object and obfuscate it

  char *original_code = marshal.dumps( co );
  char *obfuscated_code = obfuscate_algorithm( original_code  );
  

• Create wrapper script "xxx.py", ${obfuscated_code} stands for string constant generated in previous step.

  __pyarmor__(__name__, b'${obfuscated_code}')
  

Run or Import Obfuscated Python Scripts

When import or run this wrapper script, the first statement is to call a CFunction:

int __pyarmor__(char *name, unsigned char *obfuscated_code) 
{
  char *original_code = resotre_obfuscated_code( obfuscated_code );
  PyObject *co = marshal.loads( original_code );
  PyObject *mod = PyImport_ExecCodeModule( name, co );
}

This function accepts 2 parameters: module name and obfuscated code, then

• Restore obfuscated code
• Create a code object by original code
• Import original module (this will result in a duplicated frame in Traceback)

Run or Import Obfuscated Bytecode

After module imported, when any code object in this module is called first time, from the wrapped bytecode descripted in above section, we know

• First op JUMP_ABSOLUTE jumps to offset n

• At offset n, the instruction is to call a PyCFunction. This function will restore those obfuscated bytecode between offset 3 and n, and place the original bytecode at offset 0

• After function call, the last instruction jumps back to offset 0. The real bytecode is now executed

Refer to Pyarmor

I had the same problem on Windows 7 64-bit Pro. I adjusted network adapters binding using Control panel but nothing changed. Also metrics where showing that Win should use Ethernet adapter as primary, but it didn't.

Then a tried to uninstall Ethernet adapter driver and then install it again (without restart) and then I checked metrics for sure.

After this, Windows started prioritize Ethernet adapter.

If you get the "Failed to find DDMS files..." do this:

1. Open eclipse
2. Open install new software
3. Click "Add..." -> type in (e.g.) "Android_over_HTTP" and in address put "http://dl-ssl.google.com/android/eclipse/".

Don't be alarmed that its not https, this helps to fetch stuff over http. This trick helped me to resolve the issue on MAC, I believe that this also should work on Windows / Linux

Hope this helps !

What about this:

from operator import itemgetter
itemgetter(0,2,3)(myList)
('foo', 'baz', 'quux')

Per the Express (Version 4+) docs, you can use:

res.status(400);
res.send('None shall pass');

http://expressjs.com/4x/api.html#res.status

<=3.8

res.statusCode = 401;
res.send('None shall pass');

Doing

sudo sh -c "echo >> somefile"

should work. The problem is that > and >> are handled by your shell, not by the "sudoed" command, so the permissions are your ones, not the ones of the user you are "sudoing" into.

Try this:

var res = list.ToDictionary(x => x, x => x);

The first lambda lets you pick the key, the second one picks the value.

You can play with it and make values differ from the keys, like this:

var res = list.ToDictionary(x => x, x => string.Format("Val: {0}", x));

If your list contains duplicates, add Distinct() like this:

var res = list.Distinct().ToDictionary(x => x, x => x);

EDIT To comment on the valid reason, I think the only reason that could be valid for conversions like this is that at some point the keys and the values in the resultant dictionary are going to diverge. For example, you would do an initial conversion, and then replace some of the values with something else. If the keys and the values are always going to be the same, HashSet<String> would provide a much better fit for your situation:

var res = new HashSet<string>(list);
if (res.Contains("string1")) ...

If the project is Maven, you can try this way :

1. right click the "Maven Dependencies"-->"Build Path"-->"Remove from the build path";
2. right click the project ,navigate to "Maven"--->"Update project....";

Then the import issue should be solved .

I'm using jquery datepicker to select date. My directive read date and convert it to json date format (in milliseconds) store in ng-model data while display formatted date.and reverse if ng-model have json date (in millisecond) my formatter display in my format as jquery datepicker.

Html Code:

<input type="text" jqdatepicker  ng-model="course.launchDate" required readonly />

Angular Directive:

myModule.directive('jqdatepicker', function ($filter) {
    return {
        restrict: 'A',
        require: 'ngModel',
         link: function (scope, element, attrs, ngModelCtrl) {
            element.datepicker({
                dateFormat: 'dd/mm/yy',
                onSelect: function (date) {   
                    var ar=date.split("/");
                    date=new Date(ar[2]+"-"+ar[1]+"-"+ar[0]);
                    ngModelCtrl.$setViewValue(date.getTime());            
                    scope.$apply();
                }
            });
            ngModelCtrl.$formatters.unshift(function(v) {
            return $filter('date')(v,'dd/MM/yyyy'); 
            });

        }
    };
});

Creating Custom ProgressBar like hotstar.

1. Add Progress bar on layout file and set the indeterminateDrawable with drawable file.

activity_main.xml

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:id="@+id/player_progressbar"
    android:indeterminateDrawable="@drawable/custom_progress_bar"
    />

2. Create new xml file in res\drawable

custom_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
    <rotate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="2000"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="1080" >

    <shape
        android:innerRadius="35dp"
        android:shape="ring"
        android:thickness="3dp"
        android:useLevel="false" >
       <size
           android:height="80dp"
           android:width="80dp" />

       <gradient
            android:centerColor="#80b7b4b2"
            android:centerY="0.5"
            android:endColor="#f4eef0"
            android:startColor="#00938c87"
            android:type="sweep"
            android:useLevel="false" />
    </shape>

</rotate>

2854 megabytes is used. Next I open an R session and create a large matrix of random numbers:

Ofcourse you use Windows, but you could repeat this excercise in Windows and report how the available memory develops before and after you create this large dataset in R.

JAVA HOME is used for setting up the environment variable for JAVA. It means that you are providing a path for compiling a JAVA program and also running the same. So, if you do not set the JAVA HOME( PATH ) and try to run a java or any dependent program in the command prompt.

You will deal with an error as javac : not recognized as internal or external command. Now to set this, Just open your Java jdk then open bin folder then copy the PATH of that bin folder.

Now, go to My computer right click on it----> select properties-----> select Advanced system settings----->Click on Environment Variables------>select New----->give a name in the text box Variable Name and then paste the path in Value.

That's All!!

null: absence of value for a variable; undefined: absence of variable itself;

..where variable is a symbolic name associated with a value.

JS could be kind enough to implicitly init newly declared variables with null, but it does not.

In your Page_Load you will want to clear out the normal output and write your own, for example:

string json = "{\"name\":\"Joe\"}";
Response.Clear();
Response.ContentType = "application/json; charset=utf-8";
Response.Write(json);
Response.End();

To convert a C# object to JSON you can use a library such as Json.NET.

Instead of getting your .aspx page to output JSON though, consider using a Web Service (asmx) or WCF, both of which can output JSON.

If you're array structure will always be multi-dimensional in that exact fashion, then we can iterate through the elements like such:

$fh = fopen('somefile.csv', 'w') or die('Cannot open the file');

for( $i=0; $i<count($arr); $i++ ){
    $str = implode( ',', $arr[$i] );
    fwrite( $fh, $str );
    fwrite( $fh, "\n" );
}
fclose($fh);

That's one way to do it ... you could do it manually but this way is quicker and easier to understand and read.

Then you would manage your headers something what complex857 is doing to spit out the file. You could then delete the file using unlink() if you no longer needed it, or you could leave it on the server if you wished.

HTML page

<div id="overlay">
<img src="<?php echo base_url()?>assest/website/images/loading1.gif" alt="Loading" />
 Loading...
</div>

Script

$(window).load(function(){ 
 //PAGE IS FULLY LOADED 
 //FADE OUT YOUR OVERLAYING DIV
 $('#overlay').fadeOut();
});

They are the same, Bool is just System.Boolean shortened. Use Boolean when you are with a VB.net programmer, since it works with both C# and Vb

$("#theDiv").append("<img id='theImg' src='theImg.png'/>");

You need to read the documentation here.

Well, you can achieve that with Jackson, too. (and it seems to be more comfortable since you were considering using jackson).

Use ObjectMapper's convertValue method:

final ObjectMapper mapper = new ObjectMapper(); // jackson's objectmapper
final MyPojo pojo = mapper.convertValue(map, MyPojo.class);

No need to convert into JSON string or something else; direct conversion does much faster.

Use a regular expression.

WHERE name REGEXP '^[aeiou].*[aeiou]$'

^ and $ anchor the match to the beginning and end of the value.

In my test, this won't use an index on the name column, so it will need to perform a full scan, as would

WHERE name LIKE 'a%a' OR name LIKE 'a%e' ...

I think to make it use an index you'd need to use a union of queries that each test the first letter.

SELECT * FROM table
WHERE name LIKE 'a%' AND name REGEXP '[aeiou]$'
UNION
SELECT * FROM table
WHERE name LIKE 'e%' AND name REGEXP '[aeiou]$'
UNION
SELECT * FROM table
WHERE name LIKE 'i%' AND name REGEXP '[aeiou]$'
UNION
SELECT * FROM table

Try the to_date function.

This function returns all user defined routines in current database.

SELECT pg_get_functiondef(p.oid) FROM pg_proc p
INNER JOIN pg_namespace ns ON p.pronamespace = ns.oid
WHERE ns.nspname = 'public';

print [x for x in range(2,100) if not [t for t in range(2,x) if not x%t]]

To kill a process by name I use the following

ps aux | grep "search-term" | grep -v grep | tr -s " " | cut -d " " -f 2 | xargs kill -9

The tr -s " " | cut -d " " -f 2 is same as awk '{print $2}'. tr supressess the tab spaces into single space and cut is provided with <SPACE> as the delimiter and the second column is requested. The second column in the ps aux output is the process id.

I'm assuming you're using DB2 for z/OS, which unfortunately (for whatever reason, I never really understood why) doesn't support using a values-list where a full-select would be appropriate.

You can use a select like below. It's a little unwieldy, but it works:

INSERT INTO tableName (col1, col2, col3, col4, col5) 
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT val1, val2, val3, val4, val5 FROM SYSIBM.SYSDUMMY1

Your statement would work on DB2 for Linux/Unix/Windows (LUW), at least when I tested it on my LUW 9.7.

Since you're using SQL 2008:

UPDATE
    table_Name

SET
    column_A  
     = CASE
        WHEN @flag = '1' THEN @new_value
        ELSE 0
    END + column_A,

    column_B  
     = CASE
        WHEN @flag = '0' THEN @new_value
        ELSE 0
    END + column_B 
WHERE
    ID = @ID

If you were using SQL 2012:

UPDATE
    table_Name
SET
    column_A  = column_A + IIF(@flag = '1', @new_value, 0),
    column_B  = column_B + IIF(@flag = '0', @new_value, 0)
WHERE
    ID = @ID

You could use a Comparator with Java's built-in methods for sorting and binary search. Suppose you have a class like this, where a and b are the fields you want to use for sorting:

class Thing { String a, b, c, d; }

You would define your Comparator:

Comparator<Thing> comparator = new Comparator<Thing>() {
  public int compare(Thing o1, Thing o2) {
    if (o1.a.equals(o2.a)) {
      return o1.b.compareTo(o2.b);
    }
    return o1.a.compareTo(o2.a);
  }
};

Then sort your list:

Collections.sort(list, comparator);

And finally do the binary search:

int i = Collections.binarySearch(list, thingToFind, comparator);

I've created go project for string formatting from template (it allow to format strings in C# or Python style, just first version for very simple cases), you could find it here https://github.com/Wissance/stringFormatter

it works in following manner:

func TestStrFormat(t *testing.T) {
    strFormatResult, err := Format("Hello i am {0}, my age is {1} and i am waiting for {2}, because i am {0}!",
                              "Michael Ushakov (Evillord666)", "34", "\"Great Success\"")
    assert.Nil(t, err)
    assert.Equal(t, "Hello i am Michael Ushakov (Evillord666), my age is 34 and i am waiting for \"Great Success\", because i am Michael Ushakov (Evillord666)!", strFormatResult)

    strFormatResult, err = Format("We are wondering if these values would be replaced : {5}, {4}, {0}", "one", "two", "three")
    assert.Nil(t, err)
    assert.Equal(t, "We are wondering if these values would be replaced : {5}, {4}, one", strFormatResult)

    strFormatResult, err = Format("No args ... : {0}, {1}, {2}")
    assert.Nil(t, err)
    assert.Equal(t, "No args ... : {0}, {1}, {2}", strFormatResult)
}

func TestStrFormatComplex(t *testing.T) {
    strFormatResult, err := FormatComplex("Hello {user} what are you doing here {app} ?", map[string]string{"user":"vpupkin", "app":"mn_console"})
    assert.Nil(t, err)
    assert.Equal(t, "Hello vpupkin what are you doing here mn_console ?", strFormatResult)
}

1. If you really mean small caps, then no, that is not possible – just as it isn’t possible to convert text to bold or italic in any text editor (as opposed to word processor). If you want to convert text to lowercase, create a visual block and press u (or U to convert to uppercase). Tilde (~) in command mode reverses case of the character under the cursor.

2. If you want to see all text in Vim in small caps, you might want to look at the guifont option, or type :set guifont=* if your Vim flavour supports GUI font chooser.

you can use OnClick="document.getElementById('formID_NOT_NAME').SUBMIT()"

There is a much simpler way to receive a result from a DialogFragment.

First, in your Activity, Fragment, or FragmentActivity you need to add in the following information:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Stuff to do, dependent on requestCode and resultCode
    if(requestCode == 1) { // 1 is an arbitrary number, can be any int
         // This is the return result of your DialogFragment
         if(resultCode == 1) { // 1 is an arbitrary number, can be any int
              // Now do what you need to do after the dialog dismisses.
         }
     }
}

The requestCode is basically your int label for the DialogFragment you called, I'll show how this works in a second. The resultCode is the code that you send back from the DialogFragment telling your current waiting Activity, Fragment, or FragmentActivity what happened.

The next piece of code to go in is the call to the DialogFragment. An example is here:

DialogFragment dialogFrag = new MyDialogFragment();
// This is the requestCode that you are sending.
dialogFrag.setTargetFragment(this, 1);     
// This is the tag, "dialog" being sent.
dialogFrag.show(getFragmentManager(), "dialog");

With these three lines you are declaring your DialogFragment, setting a requestCode (which will call the onActivityResult(...) once the Dialog is dismissed, and you are then showing the dialog. It's that simple.

Now, in your DialogFragment you need to just add one line directly before the dismiss() so that you send a resultCode back to the onActivityResult().

getTargetFragment().onActivityResult(getTargetRequestCode(), resultCode, getActivity().getIntent());
dismiss();

That's it. Note, the resultCode is defined as int resultCode which I've set to resultCode = 1; in this case.

That's it, you can now send the result of your DialogFragment back to your calling Activity, Fragment, or FragmentActivity.

Also, it looks like this information was posted previously, but there wasn't a sufficient example given so I thought I'd provide more detail.

EDIT 06.24.2016 I apologize for the misleading code above. But you most certainly cannot receive the result back to the activity seeing as the line:

dialogFrag.setTargetFragment(this, 1);

sets a target Fragment and not Activity. So in order to do this you need to use implement an InterfaceCommunicator.

In your DialogFragment set a global variable

public InterfaceCommunicator interfaceCommunicator;

Create a public function to handle it

public interface InterfaceCommunicator {
    void sendRequestCode(int code);
}

Then when you're ready to send the code back to the Activity when the DialogFragment is done running, you simply add the line before you dismiss(); your DialogFragment:

interfaceCommunicator.sendRequestCode(1); // the parameter is any int code you choose.

In your activity now you have to do two things, the first is to remove that one line of code that is no longer applicable:

dialogFrag.setTargetFragment(this, 1);  

Then implement the interface and you're all done. You can do that by adding the following line to the implements clause at the very top of your class:

public class MyClass Activity implements MyDialogFragment.InterfaceCommunicator

And then @Override the function in the activity,

@Override
public void sendRequestCode(int code) {
    // your code here
}

You use this interface method just like you would the onActivityResult() method. Except the interface method is for DialogFragments and the other is for Fragments.

The primary difference between the two is the following

• typeof is a compile time construct and returns the type as defined at compile time
• typeid is a runtime construct and hence gives information about the runtime type of the value.

typeof Reference: http://www.delorie.com/gnu/docs/gcc/gcc_36.html

typeid Reference: https://en.wikipedia.org/wiki/Typeid

I use:

Imports System.IO
Dim strPath as String=Directory.GetCurrentDirectory

it works for me with a jar target:

<jar jarfile="${server.jar}" basedir="${classes.dir}" excludes="**/client/">
  <manifest>
    <attribute name="Main-Class" value="${mainServer.class}" />
  </manifest>
</jar>

this code include all files in "classes.dir" but exclude the directory "client" from the jar.

Simple as Pie. Just make sure you fetch array size before actually performing the loop.

for(int i = 0, arraySize= mySparseArray.size(); i < arraySize; i++) {
   Object obj = mySparseArray.get(/* int key = */ mySparseArray.keyAt(i));
}

Hope this helps.

Please stop writing faulty CSV parsers!

I've seen hundreds of CSV parsers and so called tutorials for them online.

Nearly every one of them gets it wrong!

This wouldn't be such a bad thing as it doesn't affect me but people who try to write CSV readers and get it wrong tend to write CSV writers, too. And get them wrong as well. And these ones I have to write parsers for.

Please keep in mind that CSV (in order of increasing not so obviousness):

1. can have quoting characters around values
2. can have other quoting characters than "
3. can even have other quoting characters than " and '
4. can have no quoting characters at all
5. can even have quoting characters on some values and none on others
6. can have other separators than , and ;
7. can have whitespace between seperators and (quoted) values
8. can have other charsets than ascii
9. should have the same number of values in each row, but doesn't always
10. can contain empty fields, either quoted: "foo","","bar" or not: "foo",,"bar"
11. can contain newlines in values
12. can not contain newlines in values if they are not delimited
13. can not contain newlines between values
14. can have the delimiting character within the value if properly escaped
15. does not use backslash to escape delimiters but...
16. uses the quoting character itself to escape it, e.g. Frodo's Ring will be 'Frodo''s Ring'
17. can have the quoting character at beginning or end of value, or even as only character ("foo""", """bar", """")
18. can even have the quoted character within the not quoted value; this one is not escaped

If you think this is obvious not a problem, then think again. I've seen every single one of these items implemented wrongly. Even in major software packages. (e.g. Office-Suites, CRM Systems)

There are good and correctly working out-of-the-box CSV readers and writers out there:

• opencsv
• Ostermiller Java Utilities
• Apache Commons CSV

If you insist on writing your own at least read the (very short) RFC for CSV.

I suggest making site.com redirect to www.site.com for both consistency and for avoiding issues like this.

Also, consider using a cross-browser solution like PersistJS that can use each browser native storage.

Building upon the type-hints answer (https://stackoverflow.com/a/9195565/2418922), which provides a better structured way to document types of parameters, there exist also a structured manner to document both type and descriptions of parameters:

def copy_net(
    infile: (str, 'The name of the file to send'),
    host: (str, 'The host to send the file to'),
    port: (int, 'The port to connect to')):

    pass

DisplayFor is also useful for templating. You could write a template for your Model, and do something like this:

@Html.DisplayFor(m => m)

Similar to @Html.EditorFor(m => m). It's useful for the DRY principal so that you don't have to write the same display logic over and over for the same Model.

Take a look at this blog on MVC2 templates. It's still very applicable to MVC3:

http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/

It's also useful if your Model has a Data annotation. For instance, if the property on the model is decorated with the EmailAddress data annotation, DisplayFor will render it as a mailto: link.

Splits the string in text on any consecutive runs of whitespace.

words = text.split()      

Split the string in text on delimiter: ",".

words = text.split(",")   

The words variable will be a list and contain the words from text split on the delimiter.

Small Note for Windows 8 user, Intel HAX will not work if Hyper-V feature is enable. Hyper-V (like most of the virtualization tech) will exclusively lock the VT extension witch will prevent HAX to work properly. A workaround if you “need” Hyper-V too might be to stop manually the Hyper-V services when you need HAX (haven’t tested it yet through).

DECLARE @search VARCHAR(10);
SET @search = 'Cat';

WITH T(C)
AS
(
SELECT 'Cat, Dog, Sparrow, Trout, Cow, Seahorse'
)
SELECT *
FROM T 
WHERE ', ' + C + ',' LIKE '%, ' + @search + ',%'

This will of course require a full table scan for every search.

You could convert it to a string instead of printing the list directly:

print(", ".join(LIST))

If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so:

LIST = [1, "foo", 3.5, { "hello": "bye" }]
print( ", ".join( repr(e) for e in LIST ) )

Which gives the output:

1, 'foo', 3.5, {'hello': 'bye'}

You need to use the Graphics class in order to write on the bitmap.

Specifically, one of the DrawString methods.

Bitmap a = new Bitmap(@"path\picture.bmp");

using(Graphics g = Graphics.FromImage(a))
{
  g.DrawString(....); // requires font, brush etc
}

pictuteBox1.Image = a;

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

You could use DATE_ADD : (or ADDDATE with INTERVAL)

UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR) 

@Html.DropDownListFor(m => m.Departments.id, (SelectList)ViewBag.Department, "Select", htmlAttributes: new { @class = "form-control" })

In your Dockerfile, run this first:

apt-get update && apt-get install -y gnupg2

Have you tried using @JsonProperty?

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

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

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

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

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

In search of this same solution, I found what I needed under a different question in stackoverflow: Powershell-log-off-remote-session. The below one line will return a list of logged on users.

Have you seen the wiki pages on the zxing website? It seems you might find GettingStarted, DeveloperNotes and ScanningViaIntent helpful.

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.
