My way of implementation in Swift...

ConfigurationManager.swift

import Foundation

    let ConfigurationManagerSharedInstance = ConfigurationManager()
 class ConfigurationManager : NSObject {
    var globalDic: NSMutableDictionary = NSMutableDictionary()

class var sharedInstance:ConfigurationManager {
    return ConfigurationManagerSharedInstance

}

init() {

    super.init()

    println ("Config Init been Initiated, this will be called only onece irrespective of many calls")   

}

Access the globalDic from any screen of the application by the below.

Read:

 println(ConfigurationManager.sharedInstance.globalDic)  

Write:

 ConfigurationManager.sharedInstance.globalDic = tmpDic // tmpDict is any value that to be shared among the application

<style>
    .col {display:table-cell;max-width:50px;width:50px;overflow:hidden;white-space: nowrap;}
</style>
<table>
    <tr>
        <td class="col">123456789123456789</td>
    </tr>
</table>

displays 123456

By default, it uses YAFFS - Yet Another Flash File System.

In Laravel 5, there is a .env file,

It looks like

APP_ENV=local
APP_DEBUG=true
APP_KEY=YOUR_API_KEY

DB_HOST=YOUR_HOST
DB_DATABASE=YOUR_DATABASE
DB_USERNAME=YOUR_USERNAME
DB_PASSWORD=YOUR_PASSWORD

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null

Edit that .env There is .env.sample is there , try to create from that if no such .env file found.

You can use a ScheduledExecutorService for this. First you would submit it only once to begin immediately and retain the future that is created. After that you can submit a new task that would cancel the retained future after some period of time.

 ScheduledExecutorService executor = Executors.newScheduledThreadPool(2); 
 final Future handler = executor.submit(new Callable(){ ... });
 executor.schedule(new Runnable(){
     public void run(){
         handler.cancel();
     }      
 }, 10000, TimeUnit.MILLISECONDS);

This will execute your handler (main functionality to be interrupted) for 10 seconds, then will cancel (i.e. interrupt) that specific task.

OK, this error may seem obvious, but one day I was looking for an answer JUST TO FOUND OUT THAT I HAD 2 times COMPONENTS declared. it was driving me nuts as VueJS does not complain at all when you declare it 2 times, obvious I had a lot of code in between, and when I added a new component, I placed the declaration in the top, while I also had one close to the bottom. So next time looks for this first, saves a lot of time

You are building a DataGridView on the fly and set the DataSource for it. That's good, but then do you add the DataGridView to the Controls collection of the hosting form?

this.Controls.Add(dataGridView1);

By the way the code is a bit confused

String connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\Tables.accdb;Persist Security Info=True";
string sql  = "SELECT Clients  FROM Tables";
using(OleDbConnection conn = new OleDbConnection(connection))
{
     conn.Open();
     DataSet ds = new DataSet();
     DataGridView dataGridView1 = new DataGridView();
     using(OleDbDataAdapter adapter = new OleDbDataAdapter(sql,conn))
     {
         adapter.Fill(ds);
         dataGridView1.DataSource = ds;
         // Of course, before addint the datagrid to the hosting form you need to 
         // set position, location and other useful properties. 
         // Why don't you create the DataGrid with the designer and use that instance instead?
         this.Controls.Add(dataGridView1);
     }
}

EDIT After the comments below it is clear that there is a bit of confusion between the file name (TABLES.ACCDB) and the name of the table CLIENTS.
The SELECT statement is defined (in its basic form) as

 SELECT field_names_list FROM _tablename_

so the correct syntax to use for retrieving all the clients data is

 string sql  = "SELECT * FROM Clients";

where the * means -> all the fields present in the table

leDbConnection connection = 
new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet1 DS = new DataSet1();
connection.Open();

OleDbDataAdapter DBAdapter = new OleDbDataAdapter(
@"SELECT tbl_Computer.*,  tbl_Besitzer.*
  FROM tbl_Computer 
  INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
  WHERE (((tbl_Besitzer.Vorname)='ma'));", 
connection);

UTF-8 encodes characters using 1 to 4 bytes per code point. As CMS pointed out in the accepted answer, JavaScript will store each character internally using 16 bits (2 bytes).

If you parse each character in the string via a loop and count the number of bytes used per code point, and then multiply the total count by 2, you should have JavaScript's memory usage in bytes for that UTF-8 encoded string. Perhaps something like this:

      getStringMemorySize = function( _string ) {
        "use strict";

        var codePoint
            , accum = 0
        ;

        for( var stringIndex = 0, endOfString = _string.length; stringIndex < endOfString; stringIndex++ ) {
            codePoint = _string.charCodeAt( stringIndex );

            if( codePoint < 0x100 ) {
                accum += 1;
                continue;
            }

            if( codePoint < 0x10000 ) {
                accum += 2;
                continue;
            }

            if( codePoint < 0x1000000 ) {
                accum += 3;
            } else {
                accum += 4;
            }
        }

        return accum * 2;
    }

Examples:

getStringMemorySize( 'I'    );     //  2
getStringMemorySize( '?'    );     //  4
getStringMemorySize( ''   );     //  8
getStringMemorySize( 'I?' );     // 14

I have used the using Newtonsoft.Json as below. Create an object:

 public class WorklistSortColumn
  {
    [JsonProperty(PropertyName = "field")]
    public string Field { get; set; }

    [JsonProperty(PropertyName = "dir")]
    public string Direction { get; set; }

    [JsonIgnore]
    public string SortOrder { get; set; }
  }

Now Call the below method to serialize to Json object as shown below.

string sortColumn = JsonConvert.SerializeObject(worklistSortColumn);

use padding tags the above float tags didnt worked out, I used

padding left:5px; 



padding left :30px

All you need is the following snippet inside pom.xml's build/plugins:

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

The above will run in the package phase when you run

mvn clean package

And the dependencies will be copied to the outputDirectory specified in the snippet, i.e. lib in this case.

If you only want to do that occasionally, then no changes to pom.xml are required. Simply run the following:

mvn clean package dependency:copy-dependencies

To override the default location, which is ${project.build.directory}/dependencies, add a System property named outputDirectory, i.e.

    -DoutputDirectory=${project.build.directory}/lib

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

As suggested here you can also inject the HttpServletRequest as a method param, e.g.:

public MyResponseObject myApiMethod(HttpServletRequest request, ...) {
    ...
}

If you want to implement a singleton, that is a class that runs in your program with only one instance in memory throughout the execution of the application, then one of the ways to implement a singleton is to nest a private static class inside a public class. Then the inner private class only instantiates itself when its public method to access the private instance is called.

Check out this wiki article,

https://en.wikipedia.org/wiki/Singleton_pattern

The concept takes a while to chew on.

If you know the width of spaces between elements in the row and the amount of elements in a row, this would work:

Example: 3 elements in a row, 10px gap between elements

div:last-child:nth-child(3n+2) {
  flex-grow: 1
  margin-left: 10px
}

A colleague told me about this stored procedure...

USE msdb

EXEC dbo.sp_help_job

Yes, calling System.gc() doesn't guarantee that it will run, it's a request to the JVM that may be ignored. From the docs:

Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects

It's almost always a bad idea to call it because the automatic memory management usually knows better than you when to gc. It will do so when its internal pool of free memory is low, or if the OS requests some memory be handed back.

It might be acceptable to call System.gc() if you know that it helps. By that I mean you've thoroughly tested and measured the behaviour of both scenarios on the deployment platform, and you can show it helps. Be aware though that the gc isn't easily predictable - it may help on one run and hurt on another.

Leonbloy's answer is quite complete. I would only add the special case in which one needs to get the last inserted value from within a PL/pgSQL function where OPTION 3 doesn't fit exactly.

For example, if we have the following tables:

CREATE TABLE person(
   id serial,
   lastname character varying (50),
   firstname character varying (50),
   CONSTRAINT person_pk PRIMARY KEY (id)
);

CREATE TABLE client (
    id integer,
   CONSTRAINT client_pk PRIMARY KEY (id),
   CONSTRAINT fk_client_person FOREIGN KEY (id)
       REFERENCES person (id) MATCH SIMPLE
);

If we need to insert a client record we must refer to a person record. But let's say we want to devise a PL/pgSQL function that inserts a new record into client but also takes care of inserting the new person record. For that, we must use a slight variation of leonbloy's OPTION 3:

INSERT INTO person(lastname, firstname) 
VALUES (lastn, firstn) 
RETURNING id INTO [new_variable];

Note that there are two INTO clauses. Therefore, the PL/pgSQL function would be defined like:

CREATE OR REPLACE FUNCTION new_client(lastn character varying, firstn character varying)
  RETURNS integer AS
$BODY$
DECLARE
   v_id integer;
BEGIN
   -- Inserts the new person record and retrieves the last inserted id
   INSERT INTO person(lastname, firstname)
   VALUES (lastn, firstn)
   RETURNING id INTO v_id;

   -- Inserts the new client and references the inserted person
   INSERT INTO client(id) VALUES (v_id);

   -- Return the new id so we can use it in a select clause or return the new id into the user application
    RETURN v_id;
END;
$BODY$
  LANGUAGE plpgsql VOLATILE;

Now we can insert the new data using:

SELECT new_client('Smith', 'John');

or

SELECT * FROM new_client('Smith', 'John');

And we get the newly created id.

new_client
integer
----------
         1

Test Data

DECLARE @Table1 TABLE(ID INT, Value INT)
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400)

Query

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(Value AS VARCHAR(10)) [text()]
         FROM @Table1 
         WHERE ID = t.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
FROM @Table1 t
GROUP BY ID

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

You declared them, but not initialized.

int a; // declaration, unknown value
a = 0; // initialization
int a = 0; // declaration with initialization

I would also highly recommend Adminer - http://www.adminer.org/

It is much faster than phpMyAdmin, does less funky iframe stuff, and supports both MySQL and PostgreSQL.

x = int(input("Give starting number: "))
y = int(input("Give ending number: "))

P.S. Add function int()

I kept receiving the same message no matter what i did.

To fix this, i removed .gitignore and i am not getting the Github changes not staged for commit message anymore. Before it would allow me to commit once when i ran git add . and then after it would bring up the same message.

Im not sure why the .gitignore file was causing a problem but i added on my local machine and most likely didn't sync it up properly.

I have quite similar problem. And I came up with following solution.

Using notifyDataSetChanged is a bad idea. You should be more specific, then RecyclerView will save scroll state for you.

For example, if you only need to refresh, or in other words, you want each view to be rebinded, just do this:

adapter.notifyItemRangeChanged(0, adapter.getItemCount());

use the "rsh option" . e.g.:

rsync -avz --rsh='ssh -p3382' root@remote_server_name:/opt/backups

refer to: http://www.linuxquestions.org/questions/linux-software-2/rsync-ssh-on-different-port-448112/

This may work for you, try it and see if it works:

<input type="image" src="/library/graphics/cecb2.gif">

var list = [
    { date: '12/1/2011', reading: 3, id: 20055 },
    { date: '13/1/2011', reading: 5, id: 20053 },
    { date: '14/1/2011', reading: 6, id: 45652 }
];

and then access it:

alert(list[1].date);

you don't need to use *ngIf if you use ng-container

<ng-container [ngTemplateOutlet]="myTemplate === 'first' ? first : myTemplate === 
   'second' ? second : third"></ng-container>

  <ng-template #first>first</ng-template>
  <ng-template #second>second</ng-template>
  <ng-template #third>third</ng-template>

I've mostly just seen the builtin ValueError used in this situation.

This somewhat helps:

^[a-zA-Z]'?([a-zA-Z]|\.| |-)+$

Getting the friends like @nfvs describes is a good way. It outputs a multi-dimensional array with all friends with attributes id and name (ordered by id). You can see the friends photos like this:

foreach ($friends as $key=>$value) {
    echo count($value) . ' Friends';
    echo '<hr />';
    echo '<ul id="friends">';
    foreach ($value as $fkey=>$fvalue) {
        echo '<li><img src="https://graph.facebook.com/' . $fvalue->id . '/picture" title="' . $fvalue->name . '"/></li>';
    }
    echo '</ul>';
}

Sure, if this comes up a lot, make a function like this one. You can even configure it to load every time you start IPython: https://ipython.org/ipython-doc/1/config/overview.html

def print_full(x):
    pd.set_option('display.max_rows', len(x))
    print(x)
    pd.reset_option('display.max_rows')

As for coloring, getting too elaborate with colors sounds counterproductive to me, but I agree something like bootstrap's .table-striped would be nice. You could always create an issue to suggest this feature.

You can apply the .toUpperCase() directly on String variables or as an attribute to text fields. Ex: -

String str;
TextView txt;

str.toUpperCase();// will change it to all upper case OR
txt.append(str.toUpperCase());
txt.setText(str.toUpperCase());

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

using fn_my_permissions

EXECUTE AS USER = 'userName';
SELECT * FROM fn_my_permissions(NULL, 'DATABASE') 

In my case I needed a list of prefixes

colsToScale=["production", "test", "development"]
dc[dc.columns[dc.columns.str.startswith(tuple(colsToScale))]]

I had the exact same issue on my branch(lets call it branch B) and I followed three simple steps to get make it work

1. Switched to the master branch (git checkout master)
2. Did a pull on the master (git pull)
3. Created new branch (git branch C) - note here that we are now branching from master
4. Now when you are on branch C, merge with branch B (git merge B)
5. Now do a push (git push origin C) - works :)

Now you can delete branch B and then rename branch C to branch B.

Hope this helps.

Adding a utility jar for simple function is not good option. Instead assemble your own utility classes. following is possible faster implementation.

If this is something you need to do a lot in your application, or you need to chain different calls, you can create an extension method:

public static String TrimEnd(this String str, int count)
{
    return str.Substring(0, str.Length - count);
}

and call it:

string oldString = "...Hello!";
string newString = oldString.Trim(1); //returns "...Hello"

or chained:

string newString = oldString.Substring(3).Trim(1);  //returns "Hello"

jQuery("select#cboDays option[value='Wednesday']").attr("selected", "selected");

1. your understanding is right. For detailed info on {} see bash ref - parameter expansion

2. 'for' and 'while' have different syntax and offer different styles of programmer control for an iteration. Most non-asm languages offer a similar syntax.

With while, you would probably write i=0; while [ $i -lt 10 ]; do echo $i; i=$(( i + 1 )); done in essence manage everything about the iteration yourself

try this once.

$wp_query->set_404();

• Using __dict__ or vars does not work because it misses out __slots__.
• Using __dict__ and __slots__ does not work because it misses out __slots__ from base classes.
• Using dir does not work because it includes class attributes, such as methods or properties, as well as the object attributes.
• Using vars is equivalent to using __dict__.

This is the best I have:

from typing import Dict

def get_attrs( x : object ) -> Dict[str, object]:
    mro      = type( x ).mro()
    attrs    = { }
    has_dict = False
    sentinel = object()

    for klass in mro:
        for slot in getattr( klass, "__slots__", () ):
            v = getattr( x, slot, sentinel )

            if v is sentinel:
                continue

            if slot == "__dict__":
                assert not has_dict, "Multiple __dicts__?"
                attrs.update( v )
                has_dict = True
            else:
                attrs[slot] = v

    if not has_dict:
        attrs.update( getattr( x, "__dict__", { } ) )

    return attrs

Those do both mean non-breaking space, yes.   is another synonym, in hex.

Something like this should do it:

.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }

DEMO

EDIT

To do this with a larger number of columns you could build a very simple grid system. For example, something like this should work for a five column layout:

.column {_x000D_
    float: left;_x000D_
    position: relative;_x000D_
    width: 20%;_x000D_
  _x000D_
    /*for demo purposes only */_x000D_
    background: #f2f2f2;_x000D_
    border: 1px solid #e6e6e6;_x000D_
    box-sizing: border-box;_x000D_
}_x000D_
_x000D_
.column-offset-1 {_x000D_
    left: 20%;_x000D_
}_x000D_
.column-offset-2 {_x000D_
    left: 40%;_x000D_
}_x000D_
.column-offset-3 {_x000D_
    left: 60%;_x000D_
}_x000D_
.column-offset-4 {_x000D_
    left: 80%;_x000D_
}_x000D_
_x000D_
.column-inset-1 {_x000D_
    left: -20%;_x000D_
}_x000D_
.column-inset-2 {_x000D_
    left: -40%;_x000D_
}_x000D_
.column-inset-3 {_x000D_
    left: -60%;_x000D_
}_x000D_
.column-inset-4 {_x000D_
    left: -80%;_x000D_
}

<div class="container">_x000D_
   <div class="column column-one column-offset-2">Column one</div>_x000D_
   <div class="column column-two column-inset-1">Column two</div>_x000D_
   <div class="column column-three column-offset-1">Column three</div>_x000D_
   <div class="column column-four column-inset-2">Column four</div>_x000D_
   <div class="column column-five">Column five</div>_x000D_
</div>

Or, if you are lucky enough to be able to support only modern browsers, you can use flexible boxes:

.container {_x000D_
    display: flex;_x000D_
}_x000D_
_x000D_
.column {_x000D_
    flex: 1;_x000D_
    _x000D_
    /*for demo purposes only */_x000D_
    background: #f2f2f2;_x000D_
    border: 1px solid #e6e6e6;_x000D_
    box-sizing: border-box;_x000D_
}_x000D_
_x000D_
.column-one {_x000D_
    order: 3;_x000D_
}_x000D_
.column-two {_x000D_
    order: 1;_x000D_
}_x000D_
.column-three {_x000D_
    order: 4;_x000D_
}_x000D_
.column-four {_x000D_
    order: 2;_x000D_
}_x000D_
.column-five {_x000D_
    order: 5;_x000D_
}

<div class="container">_x000D_
   <div class="column column-one">Column one</div>_x000D_
   <div class="column column-two">Column two</div>_x000D_
   <div class="column column-three">Column three</div>_x000D_
   <div class="column column-four">Column four</div>_x000D_
   <div class="column column-five">Column five</div>_x000D_

I got this issue on a Web API project. Finally figured out that it was in my "///" method comments. I have these comments set to auto-generate documentation for the API methods. Something in my comments made it go crazy. I deleted all the carriage returns, special characters, etc. Not really sure which thing it didn't like, but it worked.

To enable svn run the TortoiseSVN installation program again, select "Modify" (Allows users to change the way features are installed) and install "command line client tools".

In ES2015 a.k.a ES6 version of JavaScript, a new datatype called Map is introduced.

let map = new Map([["key1", "value1"], ["key2", "value2"]]);
map.get("key1"); // => value1

check this reference for more info.

You can also just do...

x += y

https://github.com/cscott/jsshaper implements a translator from JavaScript 1.8 to ECMAScript 5.1, which would allow you to use 'for each' in code running on webkit or node.

To achieve this we need to add few line of Code in both App

App A: Which you want to open from another App. (Source)

App B: From App B you want to open App A (Destination)

Code for App A

Add few tags into the Plist of App A Open Plist Source of App A and Past below XML

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.TestApp</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>testApp.linking</string>
        </array>
    </dict>
</array>

In App delegate of App A - Get Callback here

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
// You we get the call back here when App B will try to Open 
// sourceApplication will have the bundle ID of the App B
// [url query] will provide you the whole URL 
// [url query] with the help of this you can also pass the value from App B and get that value here 
}

Now coming to App B code -

If you just want to open App A without any input parameter

-(IBAction)openApp_A:(id)sender{

    if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"testApp.linking://?"]]){
         UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"App is not available!" message:nil delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
            [alert show];

        }
}

If you want to pass parameter from App B to App A then use below Code

-(IBAction)openApp_A:(id)sender{
    if(![[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"testApp.linking://?userName=abe&registered=1&Password=123abc"]]){
         UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"App is not available!" message:nil delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
            [alert show];

        }
}

Note: You can also open App with just type testApp.linking://? on safari browser

There are a few things which new does that malloc doesn’t:

1. new constructs the object by calling the constructor of that object
2. new doesn’t require typecasting of allocated memory.
3. It doesn’t require an amount of memory to be allocated, rather it requires a number of objects to be constructed.

So, if you use malloc, then you need to do above things explicitly, which is not always practical. Additionally, new can be overloaded but malloc can’t be.

In a word, if you use C++, try to use new as much as possible.

This happened to me when:

• Even with my servlet having only the method "doPost"

• And the form method="POST"

• I tried to access the action using the URL directly, without using the form submitt. Since the default method for the URL is the doGet method, when you don't use the form submit, you'll see @ your console the http 405 error.

Solution: Use only the form button you mapped to your servlet action.

Here's an alternative solution using javascipt:

document.querySelector('.slick-prev').innerHTML = '<img src="path/to/chevron-left-image.svg">'>;
document.querySelector('.slick-next').innerHTML = '<img src="path/to/chevron-right-image.svg">'>;

Change the img to text or what ever you require.

Another solution is to check for the command's exit code.

git rev-parse 2> /dev/null; [ $? == 0 ] && echo 1

This will print 1 if you're in a git repository folder.

Short solution:

def rot13(text):
    return "".join([x if ord(x) not in range(65, 91)+range(97, 123) else
            chr(((ord(x)-97+13)%26)+97) if x.islower() else
            chr(((ord(x)-65+13)%26)+65) for x in text])

I'd say the switch is the way to go, it is both faster and better practise.

There are various links such as (http://www.blackwasp.co.uk/SpeedTestIfElseSwitch.aspx) that show benchmark tests comparing the two.

Do this if you absolutely need to use the -Format option:

$dateStr = Get-Date $date -Format "yyyMMdd"

However

$dateStr = $date.toString('yyyMMdd')

is probably more efficient.. :)

You can also do what the "Service Reference" generated code does

public class ServiceXClient : ClientBase<IServiceX>, IServiceX
{
    public ServiceXClient() { }

    public ServiceXClient(string endpointConfigurationName) :
        base(endpointConfigurationName) { }

    public ServiceXClient(string endpointConfigurationName, string remoteAddress) :
        base(endpointConfigurationName, remoteAddress) { }

    public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
        base(endpointConfigurationName, remoteAddress) { }

    public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :
        base(binding, remoteAddress) { }

    public bool ServiceXWork(string data, string otherParam)
    {
        return base.Channel.ServiceXWork(data, otherParam);
    }
}

Where IServiceX is your WCF Service Contract

Then your client code:

var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911"));
client.ServiceXWork("data param", "otherParam param");

The zoo package has the function of as.yearmon can help to convert.

require(zoo)

df$ym<-as.yearmon(df$date, "%Y %m")

The node-csv project that you are referencing is completely sufficient for the task of transforming each row of a large portion of CSV data, from the docs at: http://csv.adaltas.com/transform/:

csv()
  .from('82,Preisner,Zbigniew\n94,Gainsbourg,Serge')
  .to(console.log)
  .transform(function(row, index, callback){
    process.nextTick(function(){
      callback(null, row.reverse());
    });
});

From my experience, I can say that it is also a rather fast implementation, I have been working with it on data sets with near 10k records and the processing times were at a reasonable tens-of-milliseconds level for the whole set.

Rearding jurka's stream based solution suggestion: node-csv IS stream based and follows the Node.js' streaming API.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

pip install --upgrade --force-reinstall <package>

When upgrading, reinstall all packages even if they are already up-to-date.

pip install -I <package>
pip install --ignore-installed <package>

Ignore the installed packages (reinstalling instead).

Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -

NSLog(@"%@",documentsDirectory);

and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file

<div id="placeholder" style="position:absolute; top:0; right:0; bottom:0; left:0;"></div>

i had the same issue and niether of the above resoved it. It turns out there was an old sql task that was disabled on the bottom right corner of my ssis that i really had to look for to find. Once i deleted this all was well

If you are using gradle just update ypur gradle plugin!

Change line in build.gradle from:

classpath 'com.android.tools.build:gradle:0.9.+'

to:

classpath 'com.android.tools.build:gradle:0.11.+'

It works for me.

Note that variable buildToolsVersion (for me "20.0.0") must match your version of build-tools.

Good luck :)

In general, an "object" is an instance of a class, which is an "image"/"fingerprint" of a class created in memory (via New keyword).
The variable of object type refers to this memory location, that is, it essentially contains the address in memory.
So a parameter of object type passes a reference/"link" to an object, not a copy of the whole object.

sed does not support "non greedy" operator.

You have to use "[]" operator to exclude "/" from match.

sed 's,\(http://[^/]*\)/.*,\1,'

P.S. there is no need to backslash "/".

As of 2018 , You can make use of Object.getOwnPropertyNames() as described in Developer Mozilla Documentation

const object1 = {
  a: 1,
  b: 2,
  c: 3
};

console.log(Object.getOwnPropertyNames(object1));
// expected output: Array ["a", "b", "c"]

The essential difference between /* and / is that a servlet with mapping /* will be selected before any servlet with an extension mapping (like *.html), while a servlet with mapping / will be selected only after extension mappings are considered (and will be used for any request which doesn't match anything else---it is the "default servlet").

In particular, a /* mapping will always be selected before a / mapping. Having either prevents any requests from reaching the container's own default servlet.

Either will be selected only after servlet mappings which are exact matches (like /foo/bar) and those which are path mappings longer than /* (like /foo/*). Note that the empty string mapping is an exact match for the context root (http://host:port/context/).

See Chapter 12 of the Java Servlet Specification, available in version 3.1 at http://download.oracle.com/otndocs/jcp/servlet-3_1-fr-eval-spec/index.html.

Try using the REPLACE function:

mysql> SELECT REPLACE('www.mysql.com', 'w', 'Ww');
        -> 'WwWwWw.mysql.com'

Note that it is case sensitive.

2^31-1 bytes. So, a little less than 2^31-1 characters for varchar(max) and half that for nvarchar(max).

nchar and nvarchar

The __dict__ property of the object is a dictionary of all its other defined properties. Note that Python classes can override getattr and make things that look like properties but are not in__dict__. There's also the builtin functions vars() and dir() which are different in subtle ways. And __slots__ can replace __dict__ in some unusual classes.

Objects are complicated in Python. __dict__ is the right place to start for reflection-style programming. dir() is the place to start if you're hacking around in an interactive shell.

I have tried a few ways. But this way works perfectly for me

<img src="~/images/btn.png" class="img-responsive" id="hide" style="display: block; margin-left: auto; margin-right: auto;" />

To get all the lines of the file loaded into the variable, Delayed Expansion is needed, so do the following:

SETLOCAL EnableDelayedExpansion

for /f "Tokens=* Delims=" %%x in (version.txt) do set Build=!Build!%%x

There is a problem with some special characters, though especially ;, % and !

You might want to take a look at HERE MAP SERVICE. They have direct traffic data you can use, which is exactly what you need: https://developer.here.com/api-explorer/rest/traffic/traffic-flow-bounding-box

For example, by querying an area of interest, you might get something like this:

{
  "RWS": [
    {
      "RW": [
        {
          "FIS": [
            {
              "FI": [
                {
                  "TMC": {
                    "PC": 32483,
                    "DE": "SOHO",
                    "QD": "+",
                    "LE": 0.71682
                  },
                  "CF": [
                    {
                      "TY": "TR",
                      "SP": 9.1,
                      "SU": 9.1,
                      "FF": 17,
                      "JF": 3.2911,
                      "CN": 0.9
                    }
                  ]
                }
              ]
            }
          ],
....

This example shows a current average speed SU of 9.1, where the free flow speed FF would be 17. The Jam factor JF is 3.3, which is still considered free flow but getting sluggish. The units used (miles/km) can be defined in the API call. To avoid dealing with TMC locations, you can ask for geocoordinates of the road segments by adding responseattributes=sh in the request.

The abbreviations used can be found here Interpreting HERE Maps real-time traffic tags:

• "RWS" - A list of Roadway (RW) items
• "RW" = This is the composite item for flow across an entire roadway. A roadway item will be present for each roadway with traffic flow information available
• "FIS" = A list of Flow Item (FI) elements
• "FI" = A single flow item
• "TMC" = An ordered collection of TMC locations
• "PC" = Point TMC Location Code
• "DE" = Text description of the road
• "QD" = Queuing direction. '+' or '-'. Note this is the opposite of the travel direction in the fully qualified ID, For example for location 107+03021 the QD would be '-'
• "LE" = Length of the stretch of road. The units are defined in the file header
• "CF" = Current Flow. This element contains details about speed and Jam Factor information for the given flow item.
• "CN" = Confidence, an indication of how the speed was determined. -1.0 road closed. 1.0=100% 0.7-100% Historical Usually a value between .7 and 1.0 "FF" = The free flow speed on this
  stretch of road.
• "JF" = The number between 0.0 and 10.0 indicating the expected quality of travel. When there is a road closure, the Jam Factor will be 10. As the number approaches 10.0 the quality of travel is getting worse. -1.0 indicates that a Jam Factor could not be calculated
• "SP" = Speed (based on UNITS) capped by speed limit
• "SU" = Speed (based on UNITS) not capped by speed limit
• "TY" = Type information for the given Location Referencing container. This may be freely defined string

None of the solutions on this page worked for me, I mixed them up and made them working with Windows and Visual Studio 2019, Here's How :

#include <Windows.h>
#include <time.h> 
#include <chrono>

static int gettimeofday(struct timeval* tp, struct timezone* tzp) {
    namespace sc = std::chrono;
    sc::system_clock::duration d = sc::system_clock::now().time_since_epoch();

With Spring Boot + Spring Data it has become quite easy:

@RunWith(SpringRunner.class)
@DataJpaTest
public class MyRepositoryTest {

    @Autowired
    MyRepository subject;

    @Test
    public void myTest() throws Exception {
        subject.save(new MyEntity());
    }
}

The solution by @heez brings up the full context, this only bring up what is needed for JPA+Transaction to work. Note that the solution above will bring up a in memory test database given that one can be found on the classpath.

Try this:

moment.format().split("T")[0]

How do I concatenate two lists in Python?

As of 3.9, these are the most popular stdlib methods for concatenating two (or more) lists in python.

Footnotes

1. This is a slick solution because of its succinctness. But sum performs concatenation in a pairwise fashion, which means this is a quadratic operation as memory has to be allocated for each step. DO NOT USE if your lists are large.

2. See chain and chain.from_iterable from the docs. You will need to import itertools first. Concatenation is linear in memory, so this is the best in terms of performance and version compatibility. chain.from_iterable was introduced in 2.6.

3. This method uses Additional Unpacking Generalizations (PEP 448), but cannot generalize to N lists unless you manually unpack each one yourself.

4. a += b and a.extend(b) are more or less equivalent for all practical purposes. += when called on a list will internally call list.__iadd__, which extends the first list by the second.

Performance

2-List Concatenation¹

There's not much difference between these methods but that makes sense given they all have the same order of complexity (linear). There's no particular reason to prefer one over the other except as a matter of style.

N-List Concatenation

Plots have been generated using the perfplot module. Code, for your reference.

_{1. The iadd (+=) and extend methods operate in-place, so a copy has to be generated each time before testing. To keep things fair, all methods have a pre-copy step for the left-hand list which can be ignored.}

Comments on Other Solutions

• DO NOT USE THE DUNDER METHOD list.__add__ directly in any way, shape or form. In fact, stay clear of dunder methods, and use the operators and operator functions like they were designed for. Python has careful semantics baked into these which are more complicated than just calling the dunder directly. Here is an example. So, to summarise, a.__add__(b) => BAD; a + b => GOOD.

• Some answers here offer reduce(operator.add, [a, b]) for pairwise concatenation -- this is the same as sum([a, b], []) only more wordy.

• Any method that uses set will drop duplicates and lose ordering. Use with caution.

• for i in b: a.append(i) is more wordy, and slower than a.extend(b), which is single function call and more idiomatic. append is slower because of the semantics with which memory is allocated and grown for lists. See here for a similar discussion.

• heapq.merge will work, but its use case is for merging sorted lists in linear time. Using it in any other situation is an anti-pattern.

• yielding list elements from a function is an acceptable method, but chain does this faster and better (it has a code path in C, so it is fast).

• operator.add(a, b) is an acceptable functional equivalent to a + b. It's use cases are mainly for dynamic method dispatch. Otherwise, prefer a + b which is shorter and more readable, in my opinion. YMMV.

Here is code to get information from a Display attribute. It uses a generic method to retrieve the attribute. If the attribute is not found it converts the enum value to a string with pascal/camel case converted to title case (code obtained here)

public static class EnumHelper
{
    // Get the Name value of the Display attribute if the   
    // enum has one, otherwise use the value converted to title case.  
    public static string GetDisplayName<TEnum>(this TEnum value)
        where TEnum : struct, IConvertible
    {
        var attr = value.GetAttributeOfType<TEnum, DisplayAttribute>();
        return attr == null ? value.ToString().ToSpacedTitleCase() : attr.Name;
    }

    // Get the ShortName value of the Display attribute if the   
    // enum has one, otherwise use the value converted to title case.  
    public static string GetDisplayShortName<TEnum>(this TEnum value)
        where TEnum : struct, IConvertible
    {
        var attr = value.GetAttributeOfType<TEnum, DisplayAttribute>();
        return attr == null ? value.ToString().ToSpacedTitleCase() : attr.ShortName;
    }

    /// <summary>
    /// Gets an attribute on an enum field value
    /// </summary>
    /// <typeparam name="TEnum">The enum type</typeparam>
    /// <typeparam name="T">The type of the attribute you want to retrieve</typeparam>
    /// <param name="value">The enum value</param>
    /// <returns>The attribute of type T that exists on the enum value</returns>
    private static T GetAttributeOfType<TEnum, T>(this TEnum value)
        where TEnum : struct, IConvertible
        where T : Attribute
    {

        return value.GetType()
                    .GetMember(value.ToString())
                    .First()
                    .GetCustomAttributes(false)
                    .OfType<T>()
                    .LastOrDefault();
    }
}

And this is the extension method for strings for converting to title case:

    /// <summary>
    /// Converts camel case or pascal case to separate words with title case
    /// </summary>
    /// <param name="s"></param>
    /// <returns></returns>
    public static string ToSpacedTitleCase(this string s)
    {
        //https://stackoverflow.com/a/155486/150342
        CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
        TextInfo textInfo = cultureInfo.TextInfo;
        return textInfo
           .ToTitleCase(Regex.Replace(s, 
                        "([a-z](?=[A-Z0-9])|[A-Z](?=[A-Z][a-z]))", "$1 "));
    }

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

This constructor was deprecated in API level 26.1.0. use NotificationCompat.Builder(Context, String) instead. All posted Notifications must specify a NotificationChannel Id.

A virtual base class is a class that cannot be instantiated : you cannot create direct object out of it.

I think you are confusing two very different things. Virtual inheritance is not the same thing as an abstract class. Virtual inheritance modifies the behaviour of function calls; sometimes it resolves function calls that otherwise would be ambiguous, sometimes it defers function call handling to a class other than that one would expect in a non-virtual inheritance.

1. Read and remember each line

2. Identify the one you want to get rid of

3. Forget that one

4. Write the rest back over the top of the file

you can use this code for showing or print :

<byte_object>.decode("utf-8")

and you can use this for encode or saving :

<str_object>.encode('utf-8')

You have to dot source them:

. .\build_funtions.ps1
. .\build_builddefs.ps1

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. In this example that is written in Java, we have three type of vehicle. We create three different object and try to run their wheels method:

public class PolymorphismExample {

    public static abstract class Vehicle
    {
        public int wheels(){
            return 0;
        }
    }

    public static class Bike extends Vehicle
    {
        @Override
        public int wheels()
        {
            return 2;
        }
    }

    public static class Car extends Vehicle
    {
        @Override
        public int wheels()
        {
            return 4;
        }
    }

    public static class Truck extends Vehicle
    {
        @Override
        public int wheels()
        {
            return 18;
        }
    }

    public static void main(String[] args)
    {
        Vehicle bike = new Bike();
        Vehicle car = new Car();
        Vehicle truck = new Truck();

        System.out.println("Bike has "+bike.wheels()+" wheels");
        System.out.println("Car has "+car.wheels()+" wheels");
        System.out.println("Truck has "+truck.wheels()+" wheels");
    }

}

The result is:

I tried this code, to retrieve shared preferences from an activity, and could not get it to work:

        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
    sharedPreferences.getAll();
    Log.d("AddNewRecord", "getAll: " + sharedPreferences.getAll());
    Log.d("AddNewRecord", "Size: " + sharedPreferences.getAll().size());

Every time I tried, my preferences returned 0, even though I have 14 preferences saved by the preference activity. I finally found the answer. I added this to the preferences in the onCreate section.

getPreferenceManager().setSharedPreferencesName("defaultPreferences");

After I added this statement, my saved preferences returned as expected. I hope that this helps someone else who may experience the same issue that I did.

I like simple javascript, and I usually have jQuery around. Here's what I came up with, based off mparkuk's:

function typeInTextarea(el, newText) {
  var start = el.prop("selectionStart")
  var end = el.prop("selectionEnd")
  var text = el.val()
  var before = text.substring(0, start)
  var after  = text.substring(end, text.length)
  el.val(before + newText + after)
  el[0].selectionStart = el[0].selectionEnd = start + newText.length
  el.focus()
}

$("button").on("click", function() {
  typeInTextarea($("textarea"), "some text")
  return false
})

Here's a demo: http://codepen.io/erikpukinskis/pen/EjaaMY?editors=101

The other answers are quite good, but it would also be useful to add LIMIT 1 (or the equivalent, to prevent the checking of unnecessary rows.

Javascript is not object oriented programming(OOP) language therefore the LOOK UP process in javascript work using 'DELEGATION PROCESS' also known as prototype delegation or prototypical inheritance.

If you try to get the value of a property from an object that it doesn't have, the JavaScript engine looks to the object's prototype (and its prototype, 1 step above at a time) it's prototype chain untll the chain ends upto null which is Object.prototype == null (Standard Object Prototype). At this point if property or method is not defined than undefined is returned.

Thus with the new keyword some of the task that were manually done e.g

1. Manual Object Creation e.g newObj.
2. Hidden bond Creation using proto (aka: dunder proto) in JS spec [[prototype]] (i.e. proto)
3. referencing and assign properties to newObj
4. return of newObj object.

All is done manually.

function CreateObj(value1, value2) {
  const newObj = {};
  newObj.property1 = value1;
  newObj.property2 = value2;
  return newObj;
}
var obj = CreateObj(10,20);

obj.__proto__ === Object.prototype;              // true
Object.getPrototypeOf(obj) === Object.prototype // true

Javascript Keyword new helps to automate this process:

1. new object literal is created identified by this:{}
2. referencing and assign properties to this
3. Hidden bond Creation [[prototype]] (i.e. proto) to Function.prototype shared space.
4. implicit return of this object {}

function CreateObj(value1, value2) {
  this.property1 = value1;
  this.property2 = value2;
}

var obj = new CreateObj(10,20);
obj.__proto__ === CreateObj.prototype             // true
Object.getPrototypeOf(obj) == CreateObj.prototype // true

Calling Constructor Function without the new Keyword:

=> this: Window

function CreateObj(value1, value2) {
  var isWindowObj = this === window;
  console.log("Is Pointing to Window Object", isWindowObj);
  this.property1 = value1;
  this.property2 = value2;
}
var obj = new CreateObj(10,20); // Is Pointing to Window Object false
var obj = CreateObj(10,20); // Is Pointing to Window Object true
window.property1; // 10
window.property2; // 20

            @Override
            public void run() {
                adapter.notifyDataSetChanged();

I would recommend you having a look at the basics of conditioning in bash.

The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.

Usage:

elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)]

In short, edit your code segment to:

elif [ "$seconds" -gt 0 ]

You'd be fine with no compilation errors. Your final code segment should look like this:

#!/bin/sh    
if [ "$seconds" -eq 0 ];then
       $timezone_string="Z"
    elif [ "$seconds" -gt 0 ]
    then
       $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60`
    else
       echo "Unknown parameter"
    fi

You can use the strdup function which has the following prototype

char *strdup(const char *s1);

Example of use:

#include <string.h>

char * my_str = strdup("My string literal!");
char * my_other_str = strdup(some_const_str);

or strcpy/strncpy to your buffer

or rewrite your functions to use const char * as parameter instead of char * where possible so you can preserve the const

The Newest MySQL Versions have the new BIT data type in which you can specify the number of bits in the field, for example BIT(1) to use as Boolean type, because it can be only 0 or 1.

It's recommended to use a query parameter when the information is optional.

Route Parameters or Query Parameters?

There is no hard-and-fast rule. In general,

prefer a route parameter when

• the value is required.
• the value is necessary to distinguish one route path from another.

prefer a query parameter when

• the value is optional.
• the value is complex and/or multi-variate.

from https://angular.io/guide/router#optional-route-parameters

You just need to take out the parameter from the route path.

@RouteConfig([
{
    path: '/user/',
    component: User,
    as: 'User'
}])

In the case of an empty string, your code assumes that adding 1 to string::npos gives 0. string::npos is of type string::size_type, which is unsigned. Thus, you are relying on the overflow behaviour of addition.

return only makes sense inside a function. There is no function in your code.

Also, your code is worthy if the Department of Redundancy Department. Assuming you move it to a proper function, this would be better:

User felixhummel got very good solution, but repository with utilite has changed.

If you mean you are only getting a null return when you use NUnit, then you probably need to copy the ConnectionString value the your app.config of your application to the app.config of your test library.

When it is run by the test loader, the test assembly is loaded at runtime and will look in its own app.config (renamed to testAssembly.dll.config at compile time) rather then your applications config file.

To get the location of the assembly you're running, try

System.Reflection.Assembly.GetExecutingAssembly().Location

A quick Update, for the text "Today", the right names are:

todayText: 'Huidige', todayStatus: 'Bekijk de huidige maand',

It would help if you showed the code you are using for the simple test program. Put directly into the interpreter this seems to work.

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1, 2)

As mentioned in have debugger run application as different user (linked above), another extremely simple way to do this which doesn't require any more tools:

• Hold Shift + right-click to open a new instance of Visual Studio.

• Click "Run as different user"

  

• Enter credentials of the other user in the next pop-up window

• Open the same solution you are working with

Now when you debug the solution it will be with the other user's permissions.

Hint: if you are going to run multiple instances of Visual Studio, change the theme of it (like to "dark") so you can keep track of which one is which easily).

You can use include/include_once or require/require_once

require_once('class.php');

Alternatively, use autoloading by adding to page.php

<?php 
function my_autoloader($class) {
    include 'classes/' . $class . '.class.php';
}

spl_autoload_register('my_autoloader');

$vars = new IUarts(); 
print($vars->data);    
?>

It also works adding that __autoload function in a lib that you include on every file like utils.php.

There is also this post that has a nice and different approach.

Efficient PHP auto-loading and naming strategies

You have to call next() before you can start reading values from the first row. beforeFirst puts the cursor before the first row, so there's no data to read.

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

You can manipulate :disabled attribute in vue.js.

It will accept a boolean, if it's true, then the input gets disabled, otherwise it will be enabled...

Something like structured like below in your case for example:

<input type="text" id="name" class="form-control" name="name" v-model="form.name" :disabled="validated ? false : true">

Also read this below:

Conditionally Disabling Input Elements via JavaScript Expression

You can conditionally disable input elements inline with a JavaScript expression. This compact approach provides a quick way to apply simple conditional logic. For example, if you only needed to check the length of the password, you may consider doing something like this.

<h3>Change Your Password</h3>
<div class="form-group">
  <label for="newPassword">Please choose a new password</label>
  <input type="password" class="form-control" id="newPassword" placeholder="Password" v-model="newPassword">
</div>

<div class="form-group">
  <label for="confirmPassword">Please confirm your new password</label>
  <input type="password" class="form-control" id="confirmPassword" placeholder="Password" v-model="confirmPassword" v-bind:disabled="newPassword.length === 0 ? true : false">
</div>

Expanding on Dejw's answer (edit2):

File.open(filename,'w'){ |f|
  uri = URI.parse(url)
  Net::HTTP.start(uri.host,uri.port){ |http| 
    http.request_get(uri.path){ |res| 
      res.read_body{ |seg|
        f << seg
#hack -- adjust to suit:
        sleep 0.005 
      }
    }
  }
}

where filename and url are strings.

The sleep command is a hack that can dramatically reduce CPU usage when the network is the limiting factor. Net::HTTP doesn't wait for the buffer (16kB in v1.9.2) to fill before yielding, so the CPU busies itself moving small chunks around. Sleeping for a moment gives the buffer a chance to fill between writes, and CPU usage is comparable to a curl solution, 4-5x difference in my application. A more robust solution might examine progress of f.pos and adjust the timeout to target, say, 95% of the buffer size -- in fact that's how I got the 0.005 number in my example.

Sorry, but I don't know a more elegant way of having Ruby wait for the buffer to fill.

Edit:

This is a version that automatically adjusts itself to keep the buffer just at or below capacity. It's an inelegant solution, but it seems to be just as fast, and to use as little CPU time, as it's calling out to curl.

It works in three stages. A brief learning period with a deliberately long sleep time establishes the size of a full buffer. The drop period reduces the sleep time quickly with each iteration, by multiplying it by a larger factor, until it finds an under-filled buffer. Then, during the normal period, it adjusts up and down by a smaller factor.

My Ruby's a little rusty, so I'm sure this can be improved upon. First of all, there's no error handling. Also, maybe it could be separated into an object, away from the downloading itself, so that you'd just call autosleep.sleep(f.pos) in your loop? Even better, Net::HTTP could be changed to wait for a full buffer before yielding :-)

def http_to_file(filename,url,opt={})
  opt = {
    :init_pause => 0.1,    #start by waiting this long each time
                           # it's deliberately long so we can see 
                           # what a full buffer looks like
    :learn_period => 0.3,  #keep the initial pause for at least this many seconds
    :drop => 1.5,          #fast reducing factor to find roughly optimized pause time
    :adjust => 1.05        #during the normal period, adjust up or down by this factor
  }.merge(opt)
  pause = opt[:init_pause]
  learn = 1 + (opt[:learn_period]/pause).to_i
  drop_period = true
  delta = 0
  max_delta = 0
  last_pos = 0
  File.open(filename,'w'){ |f|
    uri = URI.parse(url)
    Net::HTTP.start(uri.host,uri.port){ |http|
      http.request_get(uri.path){ |res|
        res.read_body{ |seg|
          f << seg
          delta = f.pos - last_pos
          last_pos += delta
          if delta > max_delta then max_delta = delta end
          if learn <= 0 then
            learn -= 1
          elsif delta == max_delta then
            if drop_period then
              pause /= opt[:drop_factor]
            else
              pause /= opt[:adjust]
            end
          elsif delta < max_delta then
            drop_period = false
            pause *= opt[:adjust]
          end
          sleep(pause)
        }
      }
    }
  }
end

The permanent fix if one wants to create a new branch on the remote to mirror and track your local branch(or, vice-versa) is:

git config --global push.default current

I always configure my local git with this command after I do git clone. Although it can be applied anytime when the local-remote branch "Git fatal: The current branch has no upstream branch" error occurs.

Hope this helps. Much peace. :)

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

• what is none scope bean and when to use it?
• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

• CDI missing @ViewScoped and @FlashScoped

Short answer:

const base64Canvas = canvas.toDataURL("image/jpeg").split(';base64,')[1];

If you are deliberately displaying it for the end user, wrap the JSON text in <PRE> and <CODE> tags, e.g.:

<html>
<body>
<pre>
<code>
[
    {
        color: "red",
        value: "#f00"
    },
    {
        color: "green",
        value: "#0f0"
    },
    {
        color: "blue",
        value: "#00f"
    },
    {
        color: "cyan",
        value: "#0ff"
    },
    {
        color: "magenta",
        value: "#f0f"
    },
    {
        color: "yellow",
        value: "#ff0"
    },
    {
        color: "black",
        value: "#000"
    }
]

</code>
</pre>
</body>
</html>

Otherwise I would use JSON Viewer.

One also has this format, which is both concise and the underlying library is beautifully written (see the source code):

import scalax.io.Codec
import scalax.io.JavaConverters._

implicit val codec = Codec.UTF8

new java.io.File("hi-file.txt").asOutput.write("I'm a hi file! ... Really!")

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

What does your "data variable" look like? If it's like this:

$mydate = "2010-05-12 13:57:01";

You can simply do:

$month = date("m",strtotime($mydate));

For more information, take a look at date and strtotime.

EDIT:

To compare with an int, just do a date_format($date,"n"); which will give you the month without leading zero.

Alternatively, try one of these:

if((int)$month == 1)...
if(abs($month) == 1)...

Or something weird using ltrim, round, floor... but date_format() with "n" would be the best.

Option 1

You could also solve it by adding a transparent border to the row (tr), like this

HTML

<table>
    <tr> 
         <td>1</td>
    </tr>
    <tr> 
         <td>2</td>
    </tr>
</table>

CSS

tr {
    border-top: 12px solid transparent;
    border-bottom: 12px solid transparent;
}

Works like a charm, although if you need regular borders, then this method will sadly not work.

Option 2

Since rows act as a way to group cells, the correct way to do this, would be to use

table {
    border-collapse: inherit;
    border-spacing: 0 10px;
}

To get this in excel or csv format- right click the folder and select "copy response"- paste to excel and use text to columns.

<?php
$a=array("1"=>"302","2"=>"302","3"=>"276","4"=>"301","5"=>"302");
print_r(array_values(array_unique($a)));
?>//`output -> Array ( [0] => 302 [1] => 276 [2] => 301 )`

You could use p2pkit, or the free solution it was based on: https://github.com/GitGarage. Doesn't work very well, and its a fixer-upper for sure, but its, well, free. Works for small amounts of data transfer right now.

What other guys done , in other post is a game of content, what i did is a game of linkedlist, it reverse the LinkedList's member not reverse of a Value of members.

Public LinkedList reverse(LinkedList List)
{
       if(List == null)
               return null;
       if(List.next() == null)
              return List;
       LinkedList temp = this.reverse( List.next() );
       return temp.setNext( List );
}

Mostly if you need a concurrent list it is inside a model object (as you should not use abstract data types like a list to represent a node in a application model graph) or it is part of a particular service, you can synchronize the access yourself.

class MyClass {
  List<MyType> myConcurrentList = new ArrayList<>();
  void myMethod() {
    synchronzied(myConcurrentList) {
      doSomethingWithList;
    }
  }
}

Often this is enough to get you going. If you need to iterate, iterate over a copy of the list not the list itself and only synchronize the part where you copy the list not while you are iterating over it.

Also when concurrently working on a list you usually do something more than just adding or removing or copying, meaning that the operation becomes meaningful enough to warrent its own method and the list becomes member of a special class representing just this particular list with thread safe behavior.

Even if I agree that a concurrent list implementation is needed and Vector / Collections.sychronizeList(list) do not do the trick as for sure you need something like compareAndAdd or compareAndRemove or get(..., ifAbsentDo), even if you have a ConcurrentList implementation developers often introduce bugs by not considering what is the true transaction when working with a concurrent lists (and maps).

These scenarios where the transactions are too small for what the intended purpose of the interaction with a concurrent ADT (abstract data type) always lead to me hide the list in a special class and synchronizing access to this class objects method using the synchronized on the method level. Its the only way to be sure that the transactions are correct.

I have seen too many bugs to do it any other way - at least if the code is important and handles something like money or security or guarantees some quality of service measures (e.g sending message at least once and only once).

Not as clean as bool(c) but it was an excuse to use ternary.

def myfunc(a,b):
    return True if a.intersection(b) else False

Also using a bit of the same logic there is no need to assign to c unless you are using it for something else.

def myfunc(a,b):
    return bool(a.intersection(b))

Finally, I would assume you want a True / False value because you are going to perform some sort of boolean test with it. I would recommend skipping the overhead of a function call and definition by simply testing where you need it.

Instead of:

if (myfunc(a,b)):
    # Do something

Maybe this:

if a.intersection(b):
    # Do something

I had a slightly different situation, when both JDK and JRE 1.8.0_112 were present on my system.

I imported the new CA certificates into [JDK_FOLDER]\jre\lib\security\cacerts using the already known command:

keytool -import -trustcacerts -keystore cacerts -alias <new_ca_alias> -file <path_to_ca_cert_file>

Still, I kept getting the same PKIX path building failed error.

I added debug information to the java CLI, by using java -Djavax.net.debug=all ... > debug.log. In the debug.log file, the line that begins with trustStore is: actually pointed to the cacerts store found in [JRE_FOLDER]\lib\security\cacerts.

In my case the solution was to copy the cacerts file used by JDK (which had the new CAs added) over the one used by the JRE and that fixed the issue.

well you can always create your textviews etc dynamically and set your onclicklisteners like you would do with an adapter

Assuming that you want to insert/update single row, most optimal approach is to use SQL Server's REPEATABLE READ transaction isolation level:

SET TRANSACTION ISOLATION LEVEL REPEATABLE READ;
BEGIN TRANSACTION

    IF (EXISTS (SELECT * FROM myTable WHERE key=@key)
        UPDATE myTable SET ...
        WHERE key=@key
    ELSE
        INSERT INTO myTable (key, ...)
        VALUES (@key, ...)

COMMIT TRANSACTION

This isolation level will prevent/block subsequent repeatable read transactions from accessing same row (WHERE key=@key) while currently running transaction is open. On the other hand, operations on another row won't be blocked (WHERE key=@key2).

I think the easiest from a logical and efficiency point of view is using the queryset's exists() function, documented here:

https://docs.djangoproject.com/en/stable/ref/models/querysets/#django.db.models.query.QuerySet.exists

So in your example above I would simply write:

if User.objects.filter(email = cleaned_info['username']).exists():
    # at least one object satisfying query exists
else:
    # no object satisfying query exists

To get the content of a directory you can use

$files = Get-ChildItem "C:\Users\gerhardl\Documents\My Received Files\"

Then you can loop over this variable as well:

for ($i=0; $i -lt $files.Count; $i++) {
    $outfile = $files[$i].FullName + "out" 
    Get-Content $files[$i].FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

An even easier way to put this is the foreach loop (thanks to @Soapy and @MarkSchultheiss):

foreach ($f in $files){
    $outfile = $f.FullName + "out" 
    Get-Content $f.FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

I needed to commit my existing Git repository to an empty SVN repository.

This is how I managed to do this:

$ git checkout master
$ git branch svn
$ git svn init -s --prefix=svn/ --username <user> https://path.to.repo.com/svn/project/
$ git checkout svn
$ git svn fetch
$ git reset --hard remotes/svn/trunk
$ git merge master
$ git svn dcommit

It worked without problems. I hope this helps someone.

Since I had to authorize myself with a different username to the SVN repository (my origin uses private/public key authentication), I had to use the --username property.

Try /public_html/stats/* ?

But since the files in git status reported as to be commited that means you've already added them manually. In which case, of course, it's a bit too late to ignore. You can git rm --cache them (IIRC).

Many has been said already but keep in mind that there are a times where u don't want to output all the records from the database into your select input field ..... Key example I have been working on this school management site where I have to output all the noticeboard categories in a select statement. From my controller this is the code I wrote

Noticeboard:: groupBy()->pluck('category')->get();

This way u get distinct record as they have been grouped so no repetition of records

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

This is my working example:

You can apply apply to a subset of the original data.

 dat <- data.frame(x=c(1,2), y=c(3,4), z=c(5,6))
 apply(dat[,c('x','z')], 1, function(x) sum(x) )

or if your function is just sum use the vectorized version:

rowSums(dat[,c('x','z')])
[1] 6 8

If you want to use testFunc

 testFunc <- function(a, b) a + b
 apply(dat[,c('x','z')], 1, function(x) testFunc(x[1],x[2]))

EDIT To access columns by name and not index you can do something like this:

 testFunc <- function(a, b) a + b
 apply(dat[,c('x','z')], 1, function(y) testFunc(y['z'],y['x']))

Now that most people use Kotlin instead of Java, here is the code in Kotlin for converting a bitmap into a base64 string.

import java.io.ByteArrayOutputStream

private fun encodeImage(bm: Bitmap): String? {
        val baos = ByteArrayOutputStream()
        bm.compress(Bitmap.CompressFormat.JPEG, 100, baos)
        val b = baos.toByteArray()
        return Base64.encodeToString(b, Base64.DEFAULT)
    }

A very simple way to get around this is to open the path where pip is installed in File Explorer, and click on the path, then type cmd, this sets the path, allowing you to install way easier.

I ran into the same issue a couple days ago and all the other methods didn't work for me.

Unexpected 'continue' (T_CONTINUE)

continue is a statement (like for, or if) and must appear standalone. It cannot be used as part of an expression. Partly because continue doesn't return a value, but in an expression every sub-expression must result in some value so the overall expression results in a value. That's the difference between a statement and an expression.

That means continue cannot be used in a ternary statement or any statement that requires a return value.

Unexpected 'break' (T_BREAK)

Same goes for break; of course. It's also not usable in expression context, but a strict statement (on the same level as foreach or an if block).

Unexpected 'return' (T_RETURN)

Now this might be more surprising for return, but that's also just a block-level statement. It does return a value (or NULL) to the higher scope/function, but it does not evaluate as expression itself. ? That is: there's no point in doing return(return(false);;

I think that understanding why you can't change the referer header might help people reading this question.

From this page: https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name

From that link:

A forbidden header name is the name of any HTTP header that cannot be modified programmatically...

Modifying such headers is forbidden because the user agent retains full control over them.

Forbidden header names ... are one of the following names:

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

I know this post is old but I just wanted to add my answer!

You said to log a user out WITHOUT directing... this method DOES redirect but it returns the user to the page they were on! here's my implementation:

// every page with logout button
<?php
        // get the full url of current page
        $page = $_SERVER['PHP_SELF'];
        // find position of the last '/'
        $file_name_begin_pos = strripos($page, "/");
        // get substring from position to end 
        $file_name = substr($page, ++$fileNamePos);
    }
?>

// the logout link in your html
<a href="logout.php?redirect_to=<?=$file_name?>">Log Out</a>

// logout.php page
<?php
    session_start();
    $_SESSION = array();
    session_destroy();
    $page = "index.php";
    if(isset($_GET["redirect_to"])){
        $file = $_GET["redirect_to"];
        if ($file == "user.php"){
            // if redirect to is a restricted page, redirect to index
            $file = "index.php";
        }
    }
    header("Location: $file");
?>

and there we go!

the code that gets the file name from the full url isn't bug proof. for example if query strings are involved with un-escaped '/' in them, it will fail.

However there are many scripts out there to get the filename from url!

Happy Coding!

In my case what happened was that the user I was using had no ownership over the directory. I simply had to change ownership of the directory to that user. For example if user is ubuntu:

chown ubuntu:ubuntu -R directory-in-question

cd directory-in-question/

git clone <git repo comes here >

I came across this thread because I was looking for something similar. I like the responses and they gave me some ideas so I tested the .to_hash method and worked really well for the use case too. soo:

object.to_hash

I've recently found how to trigger mouse click event via jQuery.

    <script type="text/javascript">
    var a = $('.path > .to > .element > a')[0];
    var e = document.createEvent('MouseEvents');
    e.initEvent( 'click', true, true );
    a.dispatchEvent(e);
    </script>

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

For Intellij users, my issue was that the directory where I had my fxml files (src/main/resources), was not marked as a "Resources" directory.

Open up the module/project settings go to the sources tab and ensure that Intellij knows that the directory contains project resource files.

Go to Menu Tool -> SQL Output, Run the PL/SQL statement, the output will show on SQL Output panel.

EXPECT is a great program to use.

On Ubuntu install it with:

sudo apt-get install expect

On a CentOS Machine install it with:

yum install expect

Lets say you want to make a connection to a sftp server and then upload a local file from your local machine to the remote sftp server

#!/usr/bin/expect

spawn sftp [email protected]
expect "password:"
send "yourpasswordhere\n"
expect "sftp>"
send "cd logdirectory\n"
expect "sftp>"
send "put /var/log/file.log\n"
expect "sftp>"
send "exit\n"
interact

This opens a sftp connection with your password to the server.

Then it goes to the directory where you want to upload your file, in this case "logdirectory"

This uploads a log file from the local directory found at /var/log/ with the files name being file.log to the "logdirectory" on the remote server

I have used a different USB cable and it started working. This is weird because the USB cable (which was not detected in android studio) was charging the phone. This made me feel like there was a problem on my Mac.

However changing the cable worked for me. Just check this option as well if you got stuck with this problem.

Anyone who is interested in returning anything with any statuscode with returning ResponseMessage:

//CreateResponse(HttpStatusCode, T value)
return ResponseMessage(Request.CreateResponse(HttpStatusCode.XX, object));

To say that something "is null" means that it is a reference to the null value. Primitives (int, double, float, etc) are by definition not reference types, so they cannot have null values. You will need to find out what your database wrapper will do in this case.

I had a similar problem.

As it turned out, I ran mvn clean package install.

Correct way is mvn clean install

On Linux it's Monospace 10 pt. (the exact monospace font used may vary on different Linux distributions or versions), on Windows it's Consolas 10 pt., and on OS X it's Menlo Regular 12 pt.

^{(The color scheme is Neon, the syntax highlighting is from PackageDev, and the font is Liberation Mono}

This information is found in the Packages/Default directory (where Packages is the directory opened by the Preferences ? Browse Packages... menu option), in the Preferences (OS).sublime-settings file where OS is one of Windows, Linux, or OSX.

You should only customize the font (or any other setting) in Packages/User/Preferences.sublime-settings, opened by Preferences ? Settings—User, as Settings—Default is over-written on upgrade, and also serves as a backup in case you really screw something up in your user settings. This is the case for both the main Sublime settings as well as those for extra packages/plugins.

These default fonts are the same in Sublime Text 2, Sublime Text 3, and the new version currently in development.

You should be able to adjust the width using the .modal-dialog class selector (in conjunction with media queries or whatever strategy you're using for responsive design):

.modal-dialog {
    width: 400px;
}

The database I did most of my work on used 'Y' / 'N' as booleans. With that implementation, you can pull off some tricks like:

1. Count rows that are true:
   SELECT SUM(CASE WHEN BOOLEAN_FLAG = 'Y' THEN 1 ELSE 0) FROM X

2. When grouping rows, enforce "If one row is true, then all are true" logic:
   SELECT MAX(BOOLEAN_FLAG) FROM Y
   Conversely, use MIN to force the grouping false if one row is false.

C itself doesn't support exceptions but you can simulate them to a degree with setjmp and longjmp calls.

static jmp_buf s_jumpBuffer;

void Example() { 
  if (setjmp(s_jumpBuffer)) {
    // The longjmp was executed and returned control here
    printf("Exception happened here\n");
  } else {
    // Normal code execution starts here
    Test();
  }
}

void Test() {
  // Rough equivalent of `throw`
  longjmp(s_jumpBuffer, 42);
}

This website has a nice tutorial on how to simulate exceptions with setjmp and longjmp

From your description, it looks like that you want to "reserve" the allocated storage space of vector t_Names.

Take note that resize initialize the newly allocated vector where reserve just allocates but does not construct. Hence, 'reserve' is much faster than 'resize'

You can refer to the documentation regarding the difference of resize and reserve

Short Code

public class DB {

    public static Connection c;

    public static Connection getConnection() throws Exception {
        if (c == null) {
            Class.forName("com.mysql.jdbc.Driver");
            c =DriverManager.getConnection("jdbc:mysql://localhost:3306/DATABASE", "USERNAME", "Password");
        }
        return c;
    }

    // Send data TO Database
    public static void setData(String sql) throws Exception {
        DB.getConnection().createStatement().executeUpdate(sql);
    }

    // Get Data From Database
    public static ResultSet getData(String sql) throws Exception {
        ResultSet rs = DB.getConnection().createStatement().executeQuery(sql);
        return rs;
    }
}

Put double exclamation mark i.e !! before the function name that you want to check. If it exists, it will return true.

function abc(){
}
!!window.abc; // return true
!!window.abcd; // return false

Two ways to read file into list in python (note these are not either or) -

1. use of with - supported from python 2.5 and above
2. use of list comprehensions

1. use of with

This is the pythonic way of opening and reading files.

#Sample 1 - elucidating each step but not memory efficient
lines = []
with open("C:\name\MyDocuments\numbers") as file:
    for line in file: 
        line = line.strip() #or some other preprocessing
        lines.append(line) #storing everything in memory!

#Sample 2 - a more pythonic and idiomatic way but still not memory efficient
with open("C:\name\MyDocuments\numbers") as file:
    lines = [line.strip() for line in file]

#Sample 3 - a more pythonic way with efficient memory usage. Proper usage of with and file iterators. 
with open("C:\name\MyDocuments\numbers") as file:
    for line in file:
        line = line.strip() #preprocess line
        doSomethingWithThisLine(line) #take action on line instead of storing in a list. more memory efficient at the cost of execution speed.

the .strip() is used for each line of the file to remove \n newline character that each line might have. When the with ends, the file will be closed automatically for you. This is true even if an exception is raised inside of it.

2. use of list comprehension

This could be considered inefficient as the file descriptor might not be closed immediately. Could be a potential issue when this is called inside a function opening thousands of files.

data = [line.strip() for line in open("C:/name/MyDocuments/numbers", 'r')]

Note that file closing is implementation dependent. Normally unused variables are garbage collected by python interpreter. In cPython (the regular interpreter version from python.org), it will happen immediately, since its garbage collector works by reference counting. In another interpreter, like Jython or Iron Python, there may be a delay.

IF...ELSE... is pretty much what we've got in T-SQL. There is nothing like structured programming's CASE statement. If you have an extended set of ...ELSE IF...s to deal with, be sure to include BEGIN...END for each block to keep things clear, and always remember, consistent indentation is your friend!

Even Rest Template can be an option :

String payload = "<?xml version=\"1.0\" encoding=\"UTF-8\"?<RequestDAO>....";
    RestTemplate rest = new RestTemplate();

    HttpHeaders headers = new HttpHeaders();
    headers.add("Content-Type", "application/xml");
    headers.add("Accept", "*/*");
    HttpEntity<String> requestEntity = new HttpEntity<String>(payload, headers);
    ResponseEntity<String> responseEntity =
            rest.exchange(url, HttpMethod.PUT, requestEntity, String.class);

     responseEntity.getBody().toString();

If you really want to read through all of the back and forth on this age-old debate, do a search for "natural key" on Stack Overflow. You should get back pages of results.

EmEditor works quite well for me. It's shareware IIRC but doesn't stop working after the license expires..

Don't know if it will shrink it, but after I run git clean, I often do git repack -ad as well, which reduces the number of pack files.

I did not have the upstream branch on my local git. I had created a local branch from master, git checkout -b mybranch . I created a branch with bitbucket GUI on the upstream git and pushed my local branch (mybranch) to that upstream branch. Once I did a git fetch on my local git to retrieve the upstream branch, I could do a git branch -d mybranch.

Similar to 'Pattern.compile' there is 'RECompiler.compile' [from com.sun.org.apache.regexp.internal] where:
1. compiled code for pattern [a-z] has 'az' in it
2. compiled code for pattern [0-9] has '09' in it
3. compiled code for pattern [abc] has 'aabbcc' in it.

Thus compiled code is a great way to generalize multiple cases. Thus instead of having different code handling situation 1,2 and 3 . The problem reduces to comparing with the ascii of present and next element in the compiled code, hence the pairs. Thus
a. anything with ascii between a and z is between a and z
b. anything with ascii between 'a and a is definitely 'a'

The main disadvantage of the #define method is that the string is duplicated each time it is used, so you can end up with lots of copies of it in the executable, making it bigger.

Given that the only logical difference between the handlers is the value of the button clicked, you can use the this keyword to refer to the element which raised the event and get the val() from that. Try this:

$("button").click(function(e) {
    e.preventDefault();
    $.ajax({
        type: "POST",
        url: "/pages/test/",
        data: { 
            id: $(this).val(), // < note use of 'this' here
            access_token: $("#access_token").val() 
        },
        success: function(result) {
            alert('ok');
        },
        error: function(result) {
            alert('error');
        }
    });
});

There is a nice gem especially for uploading files : carrierwave. If the wiki does not help , there is a nice RailsCast about the best way to use it . Summarizing , there is a field type file in Rails forms , which invokes the file upload dialog. You can use it , but the 'magic' is done by carrierwave gem .

I don't know what do you mean with "how to write to a file" , but I hope this is a nice start.

The solution that worked for me in win and linux is the folling

// GET api/values
        [HttpGet("cifrado/{xml}")]
        public ActionResult<IEnumerable<string>> Cifrado(String xml)
        {
            String nombreXML = DateTime.Now.ToString("ddMMyyyyhhmmss").ToString();
            String archivo = "/app/files/"+nombreXML + ".XML";
            String comando = " --armor --recipient [email protected]  --encrypt " + archivo;
            try{
                System.IO.File.WriteAllText(archivo, xml);                
                //String comando = "C:\\GnuPG\\bin\\gpg.exe --recipient [email protected] --armor --encrypt C:\\Users\\Administrador\\Documents\\pruebas\\nuevo.xml ";
                ProcessStartInfo startInfo = new ProcessStartInfo() {FileName = "/usr/bin/gpg",  Arguments = comando }; 
                Process proc = new Process() { StartInfo = startInfo, };
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.RedirectStandardError = true;
                proc.Start();
                proc.WaitForExit();
                Console.WriteLine(proc.StandardOutput.ReadToEnd());
                return new string[] { "Archivo encriptado", archivo + " - "+ comando};
            }catch (Exception exception){
                return new string[] { archivo, "exception: "+exception.ToString() + " - "+ comando };
            }
        }

Using conditional criteria in a join is definitely different than the Where clause. The cardinality between the tables can create differences between Joins and Where clauses.

For example, using a Like condition in an Outer Join will keep all records in the first table listed in the join. Using the same condition in the Where clause will implicitly change the join to an Inner join. The record has to generally be present in both tables to accomplish the conditional comparison in the Where clause.

I generally use the style given in one of the prior answers.

tbl_A as ta
    LEFT OUTER JOIN tbl_B AS tb
            ON ta.[Desc] LIKE '%' + tb.[Desc] + '%'

This way I can control the join type.

@[Denys Séguret] has posted correct. But In my case I need new seed everytime hence below code;

Incase you need quick functions. I use like this.

func RandInt(min, max int) int {
    r := rand.New(rand.NewSource(time.Now().UnixNano()))
    return r.Intn(max-min) + min
}

func RandFloat(min, max float64) float64 {
    r := rand.New(rand.NewSource(time.Now().UnixNano()))
    return min + r.Float64()*(max-min)
}

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

For a Comparison Between Hadoop Vs Cassandra/HBase read this post.

Basically HBase enables really fast read and writes with scalability. How fast and scalable? Facebook uses it to manage its user statuses, photos, chat messages etc. HBase is so fast sometimes stacks have been developed by Facebook to use HBase as the data store for Hive itself.

Where As Hive is more like a Data Warehousing solution. You can use a syntax similar to SQL to query Hive contents which results in a Map Reduce job. Not ideal for fast, transactional systems.

in A you have used a definition of B which is not given until then , that's why the compiler is giving error .

It looks it's essential to call decode() function to make use of actual string data even after calling base64.b64decode over base64 encoded string. Because never forget it always return bytes literals.

import base64
conv_bytes = bytes('your string', 'utf-8')
print(conv_bytes)                                 # b'your string'
encoded_str = base64.b64encode(conv_bytes)
print(encoded_str)                                # b'eW91ciBzdHJpbmc='
print(base64.b64decode(encoded_str))              # b'your string'
print(base64.b64decode(encoded_str).decode())     # your string
