The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

Function Remainder(Dividend As Variant, Divisor As Variant) As Variant
    Remainder = Dividend - Divisor * Int(Dividend / Divisor)
End Function

This function always works and is the exact copy of the Excel function.

Like This:

<?= $form->field($model, 'hidden')->hiddenInput(['class' => 'form-control', 'maxlength' => true,])->label(false) ?>

One bizarre thing is that in Chrome + Firefox, the MOUSE_LEAVE event isn't dispatched for OPAQUE and TRANSPARENT.

With WINDOW it works fine. That one took some time to find out! grr...

(note: jediericb mentioned this bug - which is similar but doesn't mention MOUSE_LEAVE)

Use this:

document.write('<td width="74"><button id="button" type="button" onclick="myfunction('" + name + "')">click</button></td>')

Might be useful:

double a = 5.0/2.0;   
Console.WriteLine (a);      // 2.5

double b = 5/2;   
Console.WriteLine (b);      // 2

int c = 5/2;   
Console.WriteLine (c);      // 2

double d = 5f/2f;   
Console.WriteLine (d);      // 2.5

Let us say you have a data frame you created and named "Data_output", you can simply export it to same directory by using the following syntax.

write.csv(Data_output, "output.csv", row.names = F, quote = F)

Your annotations look fine. Here are the things to check:

• make sure the annotation is javax.persistence.Entity, and not org.hibernate.annotations.Entity. The former makes the entity detectable. The latter is just an addition.

• if you are manually listing your entities (in persistence.xml, in hibernate.cfg.xml, or when configuring your session factory), then make sure you have also listed the ScopeTopic entity

• make sure you don't have multiple ScopeTopic classes in different packages, and you've imported the wrong one.

This sets the variable _iOSDevice to true or false

_iOSDevice = !!navigator.platform.match(/iPhone|iPod|iPad/);

In case anyone is wondering what input value

<input (keydown.enter)="search($event.target.value)" />

You can use pandas. It does take some extra memory so it's not always possible, but it's very fast and easy to use.

import pandas as pd 
pd.DataFrame(np_array).to_csv("path/to/file.csv")

if you don't want a header or index, use to_csv("/path/to/file.csv", header=None, index=None)

You can get the size of your Mysql database by running the following command in Mysql client

SELECT  sum(round(((data_length + index_length) / 1024 / 1024 / 1024), 2))  as "Size in GB"
FROM information_schema.TABLES
WHERE table_schema = "<database_name>"

You can consider using a UI confirmation.

With yesnopopup.bat

@echo off

for /f "tokens=* delims=" %%# in ('yesnopopup.bat') do (
    set "result=%%#"
)

if /i result==no (
    echo user rejected the script
    exit /b 1
) 

echo continue

rem --- other commands --

the user will see the following and depending on the choice the script will continue:

with absolutely the same script you can use also iexpYNbutton.bat which will produce similar popup.

With buttons.bat you can try the following script:

@echo off

for /f "tokens=* delims=" %%# in ('buttons.bat "Yep!" "Nope!" ') do (
    set "result=%%#"
)

if /i result==2 (
    echo user rejected the script
    exit /b 1
) 

echo continue

rem --- other commands --

and the user will see:

No need for jQuery! This simple snippet works fine for me. It uses angular.element() to bind window resize event.

/**
 * Window resize event handling
 */
angular.element($window).on('resize', function () {
    console.log($window.innerWidth);
});    

Unbind event

/**
 * Window resize unbind event      
 */
angular.element($window).off('resize');

If you are running a script, instead of a statement, you can increase this by selecting Tools/Preferences/Worksheet and increasing "Max Rows to print in a script". The default is 5000, you can change it to any size.

I tried the solution suggested by LukeP and found that it doesn't support the Authorize attribute. So, I modified it a bit.

                JavaScriptSerializer serializer = new JavaScriptSerializer();

                string userData = serializer.Serialize(serializeModel);

                FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
                         1,
                         details.Name,
                         DateTime.Now,
                         DateTime.Now.AddMinutes(15),
                         false,
                         userData);

                string encTicket = FormsAuthentication.Encrypt(authTicket);
                HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
                Response.Cookies.Add(faCookie);

                return RedirectToLocal(returnUrl);
            }
        }
        return View(details);
    }

And finally in Global.asax.cs

    protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
    {
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];

        if (authCookie != null)
        {
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            PrincipalExSerializeModel serializeModel = serializer.Deserialize<PrincipalExSerializeModel>(authTicket.UserData);
            PrincipalEx newUser = new PrincipalEx(HttpContext.Current.User, serializeModel.UserExInfo);
            HttpContext.Current.User = newUser;
        }
    }

Now I can access the data in views and controllers simply by calling

User.ExInfo()

To log out I just call

AuthManager.SignOut();

where AuthManager is

HttpContext.GetOwinContext().Authentication

I found a very nice thread on the net that explains the difference in a very straightforward way : http://www.thestudentroom.co.uk/showthread.php?t=232168.

Kruskal's algorithm will grow a solution from the cheapest edge by adding the next cheapest edge, provided that it doesn't create a cycle.

Prim's algorithm will grow a solution from a random vertex by adding the next cheapest vertex, the vertex that is not currently in the solution but connected to it by the cheapest edge.

Here attached is an interesting sheet on that topic.

If you implement both Kruskal and Prim, in their optimal form : with a union find and a finbonacci heap respectively, then you will note how Kruskal is easy to implement compared to Prim.

Prim is harder with a fibonacci heap mainly because you have to maintain a book-keeping table to record the bi-directional link between graph nodes and heap nodes. With a Union Find, it's the opposite, the structure is simple and can even produce directly the mst at almost no additional cost.

1. Use hashes when you only need to go one way. For example, for passwords in a system, you use hashing because you will only ever verify that the value a user entered, after hashing, matches the value in your repository. With encryption, you can go two ways.

2. hashing algorithms and encryption algorithms are just mathematical algorithms. So in that respect they are not different -- its all just mathematical formulas. Semantics wise, though, there is the very big distinction between hashing (one-way) and encryption(two-way). Why are hashes irreversible? Because they are designed to be that way, because sometimes you want a one-way operation.

You have to use GROUP BY so you will have multiple records returned,

SELECT  COUNT(*) TotalCount, 
        b.category_id, 
        b.category_name 
FROM    table1 a
        INNER JOIN table2 b
            ON a.category_id = b.category_id 
WHERE   a.colour <> 'red'
GROUP   BY b.category_id, b.category_name

I listened to that podcast, and it was amusing, but the security argument made no sense to me. If you've compromised server A, and that server can access data on server B, then you instantly have access to the data on server B.

You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.

Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt) such as /mnt/c/Users/yourusername/files within WSL. These files stay synced between WSL and Windows.

For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/

Log4js is one of the most popular logging library for nodejs application.

It supports many cool features:

1. Coloured console logging
2. Replacement of node's console.log functions (optional)
3. File appender, with log rolling based on file size
4. SMTP, GELF, hook.io, Loggly appender
5. Multiprocess appender (useful when you've got worker processes)
6. A logger for connect/express servers
7. Configurable log message layout/patterns
8. Different log levels for different log categories (make some parts of your app log as DEBUG, others only ERRORS, etc.)

Example:

1. Installation: npm install log4js

2. Configuration (./config/log4js.json):

   {"appenders": [
       {
           "type": "console",
           "layout": {
               "type": "pattern",
               "pattern": "%m"
           },
           "category": "app"
       },{
           "category": "test-file-appender",
           "type": "file",
           "filename": "log_file.log",
           "maxLogSize": 10240,
           "backups": 3,
           "layout": {
               "type": "pattern",
               "pattern": "%d{dd/MM hh:mm} %-5p %m"
           }
       }
   ],
   "replaceConsole": true }
   

3. Usage:

   var log4js = require( "log4js" );
   log4js.configure( "./config/log4js.json" );
   var logger = log4js.getLogger( "test-file-appender" );
   // log4js.getLogger("app") will return logger that prints log to the console
   logger.debug("Hello log4js");// store log in file
   

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.

For example if you delete a record using ORM, and your DELETE CASCADE will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.

Nowadays, in Python 2.7 and up, you can use a dict comprehension:

{k: v for k, v in points.iteritems() if v[0] < 5 and v[1] < 5}

And in Python 3:

{k: v for k, v in points.items() if v[0] < 5 and v[1] < 5}

Use it in your routes.rb file:

devise_for :users do
    get '/users/sign_out' => 'devise/sessions#destroy'
end

No, image/jpg is not the same as image/jpeg.

You should use image/jpeg. Only image/jpeg is recognised as the actual mime type for JPEG files.

See https://tools.ietf.org/html/rfc3745, https://www.w3.org/Graphics/JPEG/ .

Serving the incorrect Content-Type of image/jpg to IE can cause issues, see http://www.bennadel.com/blog/2609-internet-explorer-aborts-images-with-the-wrong-mime-type.htm.

master = Tk()

What you did wrong was not put it inside a Define function then you hadn't used the .get function with the textvariable you had set.

I have found an app on the store which can show the name / process of a log. Since Android Studio just puts a (?) on the logs being generated by the other processes, I found it useful to know which process is generating this log. But still this app is missing the filter by the process name. You can find it here.

From MySQL 5.7 onwards, this is possible, but requires first enabling the mdl instrument in the performance_schema.setup_instruments table. You can do this temporarily (until the server is next restarted) by running:

UPDATE performance_schema.setup_instruments
SET enabled = 'YES'
WHERE name = 'wait/lock/metadata/sql/mdl';

Or permanently, by adding the following incantation to the [mysqld] section of your my.cnf file (or whatever config files MySQL reads from on your installation):

[mysqld]
performance_schema_instrument = 'wait/lock/metadata/sql/mdl=ON'

(Naturally, MySQL will need to be restarted to make the config change take effect if you take the latter approach.)

Locks you take out after the mdl instrument has been enabled can be seen by running a SELECT against the performance_schema.metadata_locks table. As noted in the docs, GET_LOCK locks have an OBJECT_TYPE of 'USER LEVEL LOCK', so we can filter our query down to them with a WHERE clause:

mysql> SELECT GET_LOCK('foobarbaz', -1);
+---------------------------+
| GET_LOCK('foobarbaz', -1) |
+---------------------------+
|                         1 |
+---------------------------+
1 row in set (0.00 sec)

mysql> SELECT * FROM performance_schema.metadata_locks 
    -> WHERE OBJECT_TYPE='USER LEVEL LOCK'
    -> \G
*************************** 1. row ***************************
          OBJECT_TYPE: USER LEVEL LOCK
        OBJECT_SCHEMA: NULL
          OBJECT_NAME: foobarbaz
OBJECT_INSTANCE_BEGIN: 139872119610944
            LOCK_TYPE: EXCLUSIVE
        LOCK_DURATION: EXPLICIT
          LOCK_STATUS: GRANTED
               SOURCE: item_func.cc:5482
      OWNER_THREAD_ID: 35
       OWNER_EVENT_ID: 3
1 row in set (0.00 sec)

mysql> 

The meanings of the columns in this result are mostly adequately documented at https://dev.mysql.com/doc/refman/en/metadata-locks-table.html, but one point of confusion is worth noting: the OWNER_THREAD_ID column does not contain the connection ID (like would be shown in the PROCESSLIST or returned by CONNECTION_ID()) of the thread that holds the lock. Confusingly, the term "thread ID" is sometimes used as a synonym of "connection ID" in the MySQL documentation, but this is not one of those times. If you want to determine the connection ID of the connection that holds a lock (for instance, in order to kill that connection with KILL), you'll need to look up the PROCESSLIST_ID that corresponds to the THREAD_ID in the performance_schema.threads table. For instance, to kill the connection that was holding my lock above...

mysql> SELECT OWNER_THREAD_ID FROM performance_schema.metadata_locks
    -> WHERE OBJECT_TYPE='USER LEVEL LOCK'
    -> AND OBJECT_NAME='foobarbaz';
+-----------------+
| OWNER_THREAD_ID |
+-----------------+
|              35 |
+-----------------+
1 row in set (0.00 sec)

mysql> SELECT PROCESSLIST_ID FROM performance_schema.threads
    -> WHERE THREAD_ID=35;
+----------------+
| PROCESSLIST_ID |
+----------------+
|             10 |
+----------------+
1 row in set (0.00 sec)

mysql> KILL 10;
Query OK, 0 rows affected (0.00 sec)

Do you mean like this?

>>> mystring = "This isn't the right place to have \"'\" (single quotes)"
>>> mystring
'This isn\'t the right place to have "\'" (single quotes)'
>>> newstring = mystring.replace("'", "")
>>> newstring
'This isnt the right place to have "" (single quotes)'

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

I tried with a rest client.

Headers :

• POST /r/gerrit/rpc/ChangeDetailService HTTP/1.1

it works fine. I retrieve 200 OK with a good body.

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.

First, please check you have include eclipse gradle plugin. apply plugin : 'eclipse' Then go to your project directory in Terminal. Type gradle clean and then gradle eclipse. Then go to project in eclipse and refresh the project.

You can use findIndex to find the index in the array of the object and replace it as required:

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

var foundIndex = items.findIndex(x => x.id == item.id);
items[foundIndex] = item;

This assumes unique IDs. If your IDs are duplicated (as in your example), it's probably better if you use forEach:

items.forEach((element, index) => {
    if(element.id === item.id) {
        items[index] = item;
    }
});

The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.

So

if your table structure is as follow (standard table structure)

<table>
  <thead>
      <tr>
          <th> First column </th>
          <th> Second column </th>
          <th> Third column </th>        
      </tr>
  </thead>

   <tbody>
      <tr>
          <td> First column </td>
          <td> Second column </td>
          <td> Third column </td>        
      </tr>
  </tbody>

if you would like to give a width to second column then

<style> 
    table{
        table-layout:fixed;
        width: 100%;
    }

    table tr th:nth-child(2){
       width: 60%;
     }

</style>

Please look that we style the th not the td.

This behaves as expected. The URLEncoder implements the HTML Specifications for how to encode URLs in HTML forms.

From the javadocs:

This class contains static methods for converting a String to the application/x-www-form-urlencoded MIME format.

and from the HTML Specification:

application/x-www-form-urlencoded

Forms submitted with this content type must be encoded as follows:

1. Control names and values are escaped. Space characters are replaced by `+'

You will have to replace it, e.g.:

System.out.println(java.net.URLEncoder.encode("Hello World", "UTF-8").replace("+", "%20"));

I had a similar issue to this. you should be able to get the correct result multiplying by 1.0 instead of 100.See example Image attached

Select Grade, (Count(Grade)* 1.0 / (Select Count(*) From MyTable)) as Score From MyTable Group By Grade

The arguments can never be null. They just wont exist.

In other words, what you need to do is check the length of your arguments.

public static void main(String[] args)
{
    // Check how many arguments were passed in
    if(args.length == 0)
    {
        System.out.println("Proper Usage is: java program filename");
        System.exit(0);
    }
}

Use the built-in serializer in SQLAlchemy:

from sqlalchemy.ext.serializer import loads, dumps
obj = MyAlchemyObject()
# serialize object
serialized_obj = dumps(obj)

# deserialize object
obj = loads(serialized_obj)

If you're transferring the object between sessions, remember to detach the object from the current session using session.expunge(obj). To attach it again, just do session.add(obj).

I'm using version 4.4.2 and none of the other answers worked for me. But adding useMongoClient to the options and putting it into a variable that you call close on seemed to work.

var db = mongoose.connect('mongodb://localhost:27017/somedb', { useMongoClient: true })

//do stuff

db.close()

Integers (int for short) are the numbers you count with 0, 1, 2, 3 ... and their negative counterparts ... -3, -2, -1 the ones without the decimal part.

So once you introduce a decimal point, your not really dealing with integers. You're dealing with rational numbers. The Python float or decimal types are what you want to represent or approximate these numbers.

You may be used to a language that automatically does this for you(Php). Python, though, has an explicit preference for forcing code to be explicit instead implicit.

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

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

Add this android:screenOrientation="landscape" to your <activity> tag in the manifest for the specific activity that you want to be in landscape.

Edit:

To toggle the orientation from the Activity code, call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) other parameters can be found in the Android docs for ActivityInfo.

these 2 are the same:

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

As the others have said, there is no difference in the compiled code (IL) when you use either of the following:

var x1 = new object();
object x2 = new object;

I suppose Resharper warns you because it is [in my opinion] easier to read the first example than the second. Besides, what's the need to repeat the name of the type twice?

Consider the following and you'll get what I mean:

KeyValuePair<string, KeyValuePair<string, int>> y1 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

It's way easier to read this instead:

var y2 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

A little late to the party but I thought I would try to clear up some common misconceptions in jQuery event handlers. As of jQuery 1.7, .on() should be used instead of the deprecated .live(), to delegate event handlers to elements that are dynamically created at any point after the event handler is assigned.

That said, it is not a simple of switching live for on because the syntax is slightly different:

New method (example 1):

$(document).on('click', '#someting', function(){

});

Deprecated method (example 2):

$('#something').live(function(){

});

As shown above, there is a difference. The twist is .on() can actually be called similar to .live(), by passing the selector to the jQuery function itself:

Example 3:

$('#something').on('click', function(){

});

However, without using $(document) as in example 1, example 3 will not work for dynamically created elements. The example 3 is absolutely fine if you don't need the dynamic delegation.

Should $(document).on() be used for everything?

It will work but if you don't need the dynamic delegation, it would be more appropriate to use example 3 because example 1 requires slightly more work from the browser. There won't be any real impact on performance but it makes sense to use the most appropriate method for your use.

Should .on() be used instead of .click() if no dynamic delegation is needed?

Not necessarily. The following is just a shortcut for example 3:

$('#something').click(function(){

});

The above is perfectly valid and so it's really a matter of personal preference as to which method is used when no dynamic delegation is required.

• jQuery docs for .on()
• jQuery docs for .click()
• jQuery docs for .live()

       submit()">
    <option value="">All Category</option>
    <?php 
    foreach( $field['choices'] as $key => $value ){ 
       if($post_key==$key){ ?>
          <option value="<?php echo $key; ?>" selected><?php echo $value; ?></option>
<?php
   }else{?>
  <option value="<?php echo $key; ?>"><?php echo $value; ?></option>

How about

user r = {"",{}};

or

user r = {"",{'\0'}};

or

user r = {"",std::vector<unsigned char>()};

or

As explained here, you can use:

function replaceall(str,replace,with_this)
{
    var str_hasil ="";
    var temp;

    for(var i=0;i<str.length;i++) // not need to be equal. it causes the last change: undefined..
    {
        if (str[i] == replace)
        {
            temp = with_this;
        }
        else
        {
                temp = str[i];
        }

        str_hasil += temp;
    }

    return str_hasil;
}

... which you can then call using:

var str = "50.000.000";
alert(replaceall(str,'.',''));

The function will alert "50000000"

You can groupby on cols 'A' and 'B' and call size and then reset_index and rename the generated column:

In [26]:

df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})
Out[26]:
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

update

A little explanation, by grouping on the 2 columns, this groups rows where A and B values are the same, we call size which returns the number of unique groups:

In[202]:
df1.groupby(['A','B']).size()

Out[202]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

So now to restore the grouped columns, we call reset_index:

In[203]:
df1.groupby(['A','B']).size().reset_index()

Out[203]: 
     A    B  0
0   no   no  1
1   no  yes  2
2  yes   no  4
3  yes  yes  3

This restores the indices but the size aggregation is turned into a generated column 0, so we have to rename this:

In[204]:
df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})

Out[204]: 
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

groupby does accept the arg as_index which we could have set to False so it doesn't make the grouped columns the index, but this generates a series and you'd still have to restore the indices and so on....:

In[205]:
df1.groupby(['A','B'], as_index=False).size()

Out[205]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

It's generally considered a bad idea to ignore exceptions. Usually, if it's appropriate, you want to either notify the user of the issue (if they would care) or at the very least, log the exception, or print the stack trace to the console.

However, if that's truly not necessary (you're the one making the decision) then no, there's no other way to ignore an exception that forces you to catch it. The only revision, in that case, that I would suggest is explicitly listing the the class of the Exceptions you're ignoring, and some comment as to why you're ignoring them, rather than simply ignoring any exception, as you've done in your example.

by going into my browsers console > network > style.css ...clicked on it and it showed "cannot get /path/to/my/CSS", this told me my link was wrong. i changed that to the path of my CSS file.

Original path before change was localhost:3000/Example/public/style.css changing it to localhost:3000/style.css solved it.

if you are serving the file from app.use(express.static(path.join(__dirname, "public"))); or app.use(express.static("public")); your server would pass "that folder" to the browser so adding a "/yourCssName.css" link in your browser solves it

By adding other routes in your browser CSS link, you'd be telling the browser to search for the css in route specified.

in summary... check where your browser CSS link points to.

You can avoid blocking execution by writing the plot to an array, then displaying the array in a different thread. Here is an example of generating and displaying plots simultaneously using pf.screen from pyformulas 0.2.8:

import pyformulas as pf
import matplotlib.pyplot as plt
import numpy as np
import time

fig = plt.figure()

canvas = np.zeros((480,640))
screen = pf.screen(canvas, 'Sinusoid')

start = time.time()
while True:
    now = time.time() - start

    x = np.linspace(now-2, now, 100)
    y = np.sin(2*np.pi*x) + np.sin(3*np.pi*x)
    plt.xlim(now-2,now+1)
    plt.ylim(-3,3)
    plt.plot(x, y, c='black')

    # If we haven't already shown or saved the plot, then we need to draw the figure first...
    fig.canvas.draw()

    image = np.fromstring(fig.canvas.tostring_rgb(), dtype=np.uint8, sep='')
    image = image.reshape(fig.canvas.get_width_height()[::-1] + (3,))

    screen.update(image)

#screen.close()

Result:

If you have a list of column names in data.table, you want to change the class of do:

convert_to_character <- c("Quarter", "value")

dt[, convert_to_character] <- dt[, lapply(.SD, as.character), .SDcols = convert_to_character]

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

A more modern approach using Promise and async/await :

toDataURL(url) {
    return fetch(url).then((response) => {
            return response.blob();
        }).then(blob => {
            return URL.createObjectURL(blob);
        });
}

then

async download() {
        const a = document.createElement("a");
        a.href = await toDataURL("https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png");
        a.download = "myImage.png";
        document.body.appendChild(a);
        a.click();
        document.body.removeChild(a);
}

This works better, as you can show validationMessage for a specified key:

Migration files must match the pattern *_*.php, or else they won't be found. Since users.php does not match this pattern (it has no underscore), this file will not be found by the migrator.

Ideally, you should be creating your migration files using artisan:

php artisan make:migration create_users_table

This will create the file with the appropriate name, which you can then edit to flesh out your migration. The name will also include the timestamp, to help the migrator determine the order of migrations.

You can also use the --create or --table switches to add a little bit more boilerplate to help get you started:

php artisan make:migration create_users_table --create=users

The documentation on migrations can be found here.

You can't make a JPEG image transparent. You should use a format that allows transparency, like GIF or PNG.

Paint will open these files, but AFAIK it'll erase transparency if you edit the file. Use some other application like Paint.NET (it's free).

Edit: since other people have mentioned it: you can convert JPEG images into PNG, in any editor that's capable of working with both types.

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

When using an iframe, you will first have to switch to the iframe, before selecting the elements of that iframe

You can do it using:

driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();

In case if your frameId is dynamic, and you only have one iframe, you can use something like:

driver.switchTo().frame(driver.findElement(By.tagName("iframe")));

If you want to pull many thousands of records then... a few people gave the right answer of using 'scroll' (Note: Some people also suggested using "search_type=scan". This was deprecated, and in v5.0 removed. You don't need it)

Start with a 'search' query, but specifying a 'scroll' parameter (here I'm using a 1 minute timeout):

curl -XGET 'http://ip1:9200/myindex/_search?scroll=1m' -d '
{
    "query": {
            "match_all" : {}
    }
}
'

That includes your first 'batch' of hits. But we are not done here. The output of the above curl command would be something like this:

{"_scroll_id":"c2Nhbjs1OzUyNjE6NU4tU3BrWi1UWkNIWVNBZW43bXV3Zzs1Mzc3OkhUQ0g3VGllU2FhemJVNlM5d2t0alE7NTI2Mjo1Ti1TcGtaLVRaQ0hZU0FlbjdtdXdnOzUzNzg6SFRDSDdUaWVTYWF6YlU2Uzl3a3RqUTs1MjYzOjVOLVNwa1otVFpDSFlTQWVuN211d2c7MTt0b3RhbF9oaXRzOjIyNjAxMzU3Ow==","took":109,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":22601357,"max_score":0.0,"hits":[]}}

It's important to have _scroll_id handy as next you should run the following command:

    curl -XGET  'localhost:9200/_search/scroll'  -d'
    {
        "scroll" : "1m", 
        "scroll_id" : "c2Nhbjs2OzM0NDg1ODpzRlBLc0FXNlNyNm5JWUc1" 
    }
    '

However, passing the scroll_id around is not something designed to be done manually. Your best bet is to write code to do it. e.g. in java:

    private TransportClient client = null;
    private Settings settings = ImmutableSettings.settingsBuilder()
                  .put(CLUSTER_NAME,"cluster-test").build();
    private SearchResponse scrollResp  = null;

    this.client = new TransportClient(settings);
    this.client.addTransportAddress(new InetSocketTransportAddress("ip", port));

    QueryBuilder queryBuilder = QueryBuilders.matchAllQuery();
    scrollResp = client.prepareSearch(index).setSearchType(SearchType.SCAN)
                 .setScroll(new TimeValue(60000))                            
                 .setQuery(queryBuilder)
                 .setSize(100).execute().actionGet();

    scrollResp = client.prepareSearchScroll(scrollResp.getScrollId())
                .setScroll(new TimeValue(timeVal))
                .execute()
                .actionGet();

Now LOOP on the last command use SearchResponse to extract the data.

Clyde's solution works, but it is a broadcast, which I am pretty sure will be less efficient than calling a method directly. I could be mistaken, but I think the broadcasts are meant more for inter-application communication.

I'm assuming you already know how to bind a service with an Activity. I do something sort of like the code below to handle this kind of problem:

class MyService extends Service {
    MyFragment mMyFragment = null;
    MyFragment mMyOtherFragment = null;

    private void networkLoop() {
        ...

        //received new data for list.
        if(myFragment != null)
            myFragment.updateList();
        }

        ...

        //received new data for textView
        if(myFragment !=null)
            myFragment.updateText();

        ...

        //received new data for textView
        if(myOtherFragment !=null)
            myOtherFragment.updateSomething();

        ...
    }
}


class MyFragment extends Fragment {

    public void onResume() {
        super.onResume()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyFragment=this;
    }

    public void onPause() {
        super.onPause()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyFragment=null;
    }

    public void updateList() {
        runOnUiThread(new Runnable() {
            public void run() {
                //Update the list.
            }
        });
    }

    public void updateText() {
       //as above
    }
}

class MyOtherFragment extends Fragment {
             public void onResume() {
        super.onResume()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyOtherFragment=this;
    }

    public void onPause() {
        super.onPause()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyOtherFragment=null;
    }

    public void updateSomething() {//etc... }
}

I left out bits for thread safety, which is essential. Make sure to use locks or something like that when checking and using or changing the fragment references on the service.

ISO 8601 allows a compact representation with no separators except for the T, so I like to use this one-liner to get a quick timestamp string:

>>> datetime.datetime.utcnow().strftime("%Y%m%dT%H%M%S.%fZ")
'20180905T140903.591680Z'

If you don't need the microseconds, just leave out the .%f part:

>>> datetime.datetime.utcnow().strftime("%Y%m%dT%H%M%SZ")
'20180905T140903Z'

For local time:

>>> datetime.datetime.now().strftime("%Y%m%dT%H%M%S")
'20180905T140903'

Edit:

After reading up on this some more, I recommend you leave the punctuation in. RFC 3339 recommends that style because if everyone uses punctuation, there isn't a risk of things like multiple ISO 8601 strings being sorted in groups on their punctuation. So the one liner for a compliant string would be:

>>> datetime.datetime.now().strftime("%Y-%m-%dT%H:%M:%SZ")

First you need to "uncompress" userdata.img with simg2img, then you can mount it via the loop device.

A Build Lifecycle is Made Up of Phases

Each of these build lifecycles is defined by a different list of build phases, wherein a build phase represents a stage in the lifecycle.

For example, the default lifecycle comprises of the following phases (for a complete list of the lifecycle phases, refer to the Lifecycle Reference):

• validate - validate the project is correct and all necessary information is available
• compile - compile the source code of the project
• test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
• package - take the compiled code and package it in its distributable format, such as a JAR. verify - run any checks on results of integration tests to ensure quality criteria are met
• install - install the package into the local repository, for use as a dependency in other projects locally
• deploy - done in the build environment, copies the final package to the remote repository for sharing with other developers and projects.

These lifecycle phases (plus the other lifecycle phases not shown here) are executed sequentially to complete the default lifecycle. Given the lifecycle phases above, this means that when the default lifecycle is used, Maven will first validate the project, then will try to compile the sources, run those against the tests, package the binaries (e.g. jar), run integration tests against that package, verify the integration tests, install the verified package to the local repository, then deploy the installed package to a remote repository.

SQL Server 2017 does introduce a new aggregate function

STRING_AGG ( expression, separator).

Concatenates the values of string expressions and places separator values between them. The separator is not added at the end of string.

The concatenated elements can be ordered by appending WITHIN GROUP (ORDER BY some_expression)

For versions 2005-2016 I typically use the XML method in the accepted answer.

This can fail in some circumstances however. e.g. if the data to be concatenated contains CHAR(29) you see

FOR XML could not serialize the data ... because it contains a character (0x001D) which is not allowed in XML.

A more robust method that can deal with all characters would be to use a CLR aggregate. However applying an ordering to the concatenated elements is more difficult with this approach.

The method of assigning to a variable is not guaranteed and should be avoided in production code.

For in loops on Arrays is not compatible with Prototype. If you think you might need to use that library in the future, it would make sense to stick to for loops.

http://www.prototypejs.org/api/array

in my case i had a custom class-level constraint that was not being called.

@CustomValidation // not called
public class MyClass {
    @Lob
    @Column(nullable = false)
    private String name;
}

as soon as i added a field-level constraint to my class, either custom or standard, the class-level constraint started working.

@CustomValidation // now it works. super.
public class MyClass {
    @Lob
    @Column(nullable = false)
    @NotBlank // adding this made @CustomValidation start working
    private String name;
}

seems like buggy behavior to me but easy enough to work around i guess

I am not sure about your DBMS. So, I created a temporary table in Redshift and from my experience, I think this query should return what you are looking for:

select min(Id), distinct MailId, EmailAddress, Name
    from yourTableName
    group by MailId, EmailAddress, Name

I see that I am using a GROUP BY clause but you still won't have two rows against any particular MailId.

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

I would use:

val, idx = min((val, idx) for (idx, val) in enumerate(my_list))

Then val will be the minimum value and idx will be its index.

In MacOS Catalina 10.15.5 the .npmrc file path can be found at

/Users/<user-name>/.npmrc

Open in it in (for first time users, create a new file) any editor and copy-paste your token. Save it.

You are ready to go.

Note: As mentioned by @oligofren, the command npm config ls -l will npm configurations. You will get the .npmrc file from config parameter userconfig

Try this:

List<string> names = new List<string>("Tom,Scott,Bob".Split(','));
names.Reverse();

I got the same error when trying to compile a Go package on Debian 9.8:

# pkg-config --cflags  -- libssl libcrypto
Package libssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libssl.pc'

The thing is that pkg-config searches for package meta-information in .pc files. Such files come from the dev package. So, even though I had libssl installed, I still got the error. It was resolved by running:

sudo apt-get install libssl-dev

Java passes primitive types by value and class types by reference

Now, people like to bicker endlessly about whether "pass by reference" is the correct way to describe what Java et al. actually do. The point is this:

1. Passing an object does not copy the object.
2. An object passed to a function can have its members modified by the function.
3. A primitive value passed to a function cannot be modified by the function. A copy is made.

In my book that's called passing by reference.

— Brian Bi - Which programming languages are pass by reference?

The accepted answer lists only the filenames, but to get the top 5 files one can also use:

ls -lht | head -6

where:

-l outputs in a list format

-h makes output human readable (i.e. file sizes appear in kb, mb, etc.)

-t sorts output by placing most recently modified file first

head -6 will show 5 files because ls prints the block size in the first line of output.

I think this is a slightly more elegant and possibly more useful approach.

Example output:

total 26960312 -rw-r--r--@ 1 user staff 1.2K 11 Jan 11:22 phone2.7.py -rw-r--r--@ 1 user staff 2.7M 10 Jan 15:26 03-cookies-1.pdf -rw-r--r--@ 1 user staff 9.2M 9 Jan 16:21 Wk1_sem.pdf -rw-r--r--@ 1 user staff 502K 8 Jan 10:20 lab-01.pdf -rw-rw-rw-@ 1 user staff 2.0M 5 Jan 22:06 0410-1.wmv

For me it was having a file called ~/.editorconfig that was overriding my tab settings. I removed that (surely that will bite me again someday) but it fixed my pycharm issue

Sometime some C# approach makes the life easier in Java world..:

class XLINK {
static final short PAYLOAD = 102, ACK = 103, PAYLOAD_AND_ACK = 104;
}
//Now is trivial to use it like a C# enum:
int rcv = XLINK.ACK;

I realize this has been answered, but I used a different approach and thought it might be worth sharing. Also, I feel like my approach might produce unwanted overhead. However, I'm not able to observer or calculate anything happening that is that bad under the loads we observe. I was looking for any useful feedback on this approach.

The problem with working with dynamics is that you can't attach any functions to the dynamic object directly. You have to use something that can figure out the assignments that you don't want to figure out every time.

When planning this simple solution, I looked at what the valid intermediaries are when attempting to retype similar objects. I found that a binary array, string (xml, json) or hard coding a conversion (IConvertable) were the usual approaches. I don't want to get into binary conversions due to a code maintainability factor and laziness.

My theory was that Newtonsoft could do this by using a string intermediary.

As a downside, I am fairly certain that when converting the string to an object, that it would use reflection by searching the current assembly for an object with matching properties, create the type, then instantiate the properties, which would require more reflection. If true, all of this can be considered avoidable overhead.

C#:

//This lives in a helper class
public static ConvertDynamic<T>(dynamic data)
{
     return Newtonsoft.Json.JsonConvert.DeserializeObject<T>(Newtonsoft.Json.JsonConvert.SerializeObject(data));
}

//Same helper, but in an extension class (public static class),
//but could be in a base class also.
public static ToModelList<T>(this List<dynamic> list)
{
    List<T> retList = new List<T>();
    foreach(dynamic d in list)
    {
        retList.Add(ConvertDynamic<T>(d));
    }
}

With that said, this fits another utility I've put together that lets me make any object into a dynamic. I know I had to use reflection to do that correctly:

public static dynamic ToDynamic(this object value)
{
    IDictionary<string, object> expando = new ExpandoObject();

    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(value.GetType()))
        expando.Add(property.Name, property.GetValue(value));

    return expando as ExpandoObject;
}

I had to offer that function. An arbitrary object assigned to a dynamic typed variable cannot be converted to an IDictionary, and will break the ConvertDynamic function. For this function chain to be used it has to be provided a dynamic of System.Dynamic.ExpandoObject, or IDictionary<string, object>.

To elaborate on Paul's answer, this is the controller logic that coincides with the template code.

// HTML
<div class="row" ng-repeat="thing in things">
  <div class="well" ng-class="isLast($last)">
      <p>Data-driven {{thing.name}}</p>
  </div>
</div>

// CSS
.last { /* Desired Styles */}

// Controller
$scope.isLast = function(check) {
    var cssClass = check ? 'last' : null;
    return cssClass;
};

Its also worth noting that you really should avoid this solution if possible. By nature CSS can handle this, making a JS-based solution is unnecessary and non-performant. Unfortunately if you need to support IE8> this solution won't work for you (see MDN support docs).

CSS-Only Solution

// Using the above example syntax
.row:last-of-type { /* Desired Style */ }

In addition to this answer, note that in Node.js if you access JSON with the array syntax [] all nested JSON keys should follow that syntax

This is the wrong way

json.first.second.third['comment']

and will will give you the 'undefined' error.

This is the correct way

json['first']['second']['third']['comment'] 

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

 " Every object (including functions) has this internal property called [[prototype]]" 

Every function has a proto- type object that’s automatically set as the prototype of the objects created with that function.

you guys can check easily:

const a = { name: "something" };
console.log(a.prototype); // undefined because it is not directly accessible

const b = function () {
  console.log("somethign");};

console.log(b.prototype); // returns b {}

But every function and objects has __proto__ property which points to the prototype of that object or function. __proto__ and prototype are 2 different terms. I think we can make this comment: "Every object is linked to a prototype via the proto " But __proto__ does not exist in javascript. this property is added by browser just to help for debugging.

console.log(a.__proto__); // returns {}
console.log(b.__proto__); // returns [Function]

You guys can check this on the terminal easily. So what is constructor function.

function CreateObject(name,age){
    this.name=name;
    this.age =age
}

5 things that pay attention first:

1- When constructor function is invoked with new, the function’s internal [[Construct]] method is called to create a new instance object and allocate memory.

2- We are not using return keyword. new will handle it.

3- Name of the function is capitalized so when developers see your code they can understand that they have to use new keyword.

4- We do not use arrow function. Because the value of the this parameter is picked up at the moment that the arrow function is created which is "window". arrow functions are lexically scoped, not dynamically. Lexically here means locally. arrow function carries its local "this" value.

5- Unlike regular functions, arrow functions can never be called with the new keyword because they do not have the [[Construct]] method. The prototype property also does not exist for arrow functions.

const me=new CreateObject("yilmaz","21")

new invokes the function and then creates an empty object {} and then adds "name" key with the value of "name", and "age" key with the value of argument "age".

When we invoke a function, a new execution context is created with "this" and "arguments", that is why "new" has access to these arguments.

By default this inside the constructor function will point to the "window" object, but new changes it. "this" points to the empty object {} that is created and then properties are added to newly created object. If you had any variable that defined without "this" property will no be added to the object.

function CreateObject(name,age){
    this.name=name;
    this.age =age;
    const myJob="developer"
}

myJob property will not added to the object because there is nothing referencing to the newly created object.

   const me= {name:"yilmaz",age:21} // there is no myJob key

in the beginning I said every function has "prototype" property including constructor functions. We can add methods to the prototype of the constructor, so every object that created from that function will have access to it.

 CreateObject.prototype.myActions=function(){ //define something}

Now "me" object can use "myActions" method.

javascript has built-in constructor functions: Function,Boolean,Number,String..

if I create

const a = new Number(5);
console.log(a);  // [Number: 5]
console.log(typeof a); // object

Anything that created by using new has type of object. now "a" has access all of the methods that are stored inside Number.prototype. If I defined

const b = 5;
console.log(a === b);//false

a and b are 5 but a is object and b is primitive. even though b is primitive type, when it is created, javascript automatically wraps it with Number(), so b has access to all of the methods that inside Number.prototype.

Constructor function is useful when you want to create multiple similar objects with the same properties and methods. That way you will not be allocating extra memory so your code will run more efficiently.

try it ! also can calculate NA's data!

df <- data.frame(a1=1:10, a2=11:20)

df %>% summarise_each(funs( mean( .,na.rm = TRUE)))


# a1   a2
# 5.5 15.5

I don't know how it works, but you can also use it to tab your values !

Example :

Console.WriteLine($"I can tab like {"this !", 5}.");

Of course, you can replace "this !" with any variable or anything meaningful, just as you can also change the tab.

I want to give a different view of MONEY vs. NUMERICAL, largely based my own expertise and experience... My point of view here is MONEY, because I have worked with it for a considerable long time and never really used NUMERICAL much...

MONEY Pro:

• Native Data Type. It uses a native data type (integer) as the same as a CPU register (32 or 64 bit), so the calculation doesn't need unnecessary overhead so it's smaller and faster... MONEY needs 8 bytes and NUMERICAL(19, 4) needs 9 bytes (12.5% bigger)...

  MONEY is faster as long as it is used for it was meant to be (as money). How fast? My simple SUM test on 1 million data shows that MONEY is 275 ms and NUMERIC 517 ms... That is almost twice as fast... Why SUM test? See next Pro point

• Best for Money. MONEY is best for storing money and do operations, for example, in accounting. A single report can run millions of additions (SUM) and a few multiplications after the SUM operation is done. For very big accounting applications it is almost twice as fast, and it is extremely significant...
• Low Precision of Money. Money in real life doesn't need to be very precise. I mean, many people may care about 1 cent USD, but how about 0.01 cent USD? In fact, in my country, banks no longer care about cents (digit after decimal comma); I don't know about US bank or other country...

MONEY Con:

• Limited Precision. MONEY only has four digits (after the comma) precision, so it has to be converted before doing operations such as division... But then again money doesn't need to be so precise and is meant to be used as money, not just a number...

But... Big, but here is even your application involved real-money, but do not use it in lots of SUM operations, like in accounting. If you use lots of divisions and multiplications instead then you should not use MONEY...

I am using PostgreSQL with closure tables for my hierarchies. I have one universal stored procedure for the whole database:

CREATE FUNCTION nomen_tree() RETURNS trigger
    LANGUAGE plpgsql
    AS $_$
DECLARE
  old_parent INTEGER;
  new_parent INTEGER;
  id_nom INTEGER;
  txt_name TEXT;
BEGIN
-- TG_ARGV[0] = name of table with entities with PARENT-CHILD relationships (TBL_ORIG)
-- TG_ARGV[1] = name of helper table with ANCESTOR, CHILD, DEPTH information (TBL_TREE)
-- TG_ARGV[2] = name of the field in TBL_ORIG which is used for the PARENT-CHILD relationship (FLD_PARENT)
    IF TG_OP = 'INSERT' THEN
    EXECUTE 'INSERT INTO ' || TG_ARGV[1] || ' (child_id,ancestor_id,depth) 
        SELECT $1.id,$1.id,0 UNION ALL
      SELECT $1.id,ancestor_id,depth+1 FROM ' || TG_ARGV[1] || ' WHERE child_id=$1.' || TG_ARGV[2] USING NEW;
    ELSE                                                           
    -- EXECUTE does not support conditional statements inside
    EXECUTE 'SELECT $1.' || TG_ARGV[2] || ',$2.' || TG_ARGV[2] INTO old_parent,new_parent USING OLD,NEW;
    IF COALESCE(old_parent,0) <> COALESCE(new_parent,0) THEN
      EXECUTE '
      -- prevent cycles in the tree
      UPDATE ' || TG_ARGV[0] || ' SET ' || TG_ARGV[2] || ' = $1.' || TG_ARGV[2]
        || ' WHERE id=$2.' || TG_ARGV[2] || ' AND EXISTS(SELECT 1 FROM '
        || TG_ARGV[1] || ' WHERE child_id=$2.' || TG_ARGV[2] || ' AND ancestor_id=$2.id);
      -- first remove edges between all old parents of node and its descendants
      DELETE FROM ' || TG_ARGV[1] || ' WHERE child_id IN
        (SELECT child_id FROM ' || TG_ARGV[1] || ' WHERE ancestor_id = $1.id)
        AND ancestor_id IN
        (SELECT ancestor_id FROM ' || TG_ARGV[1] || ' WHERE child_id = $1.id AND ancestor_id <> $1.id);
      -- then add edges for all new parents ...
      INSERT INTO ' || TG_ARGV[1] || ' (child_id,ancestor_id,depth) 
        SELECT child_id,ancestor_id,d_c+d_a FROM
        (SELECT child_id,depth AS d_c FROM ' || TG_ARGV[1] || ' WHERE ancestor_id=$2.id) AS child
        CROSS JOIN
        (SELECT ancestor_id,depth+1 AS d_a FROM ' || TG_ARGV[1] || ' WHERE child_id=$2.' 
        || TG_ARGV[2] || ') AS parent;' USING OLD, NEW;
    END IF;
  END IF;
  RETURN NULL;
END;
$_$;

Then for each table where I have a hierarchy, I create a trigger

CREATE TRIGGER nomenclature_tree_tr AFTER INSERT OR UPDATE ON nomenclature FOR EACH ROW EXECUTE PROCEDURE nomen_tree('my_db.nomenclature', 'my_db.nom_helper', 'parent_id');

For populating a closure table from existing hierarchy I use this stored procedure:

CREATE FUNCTION rebuild_tree(tbl_base text, tbl_closure text, fld_parent text) RETURNS void
    LANGUAGE plpgsql
    AS $$
BEGIN
    EXECUTE 'TRUNCATE ' || tbl_closure || ';
    INSERT INTO ' || tbl_closure || ' (child_id,ancestor_id,depth) 
        WITH RECURSIVE tree AS
      (
        SELECT id AS child_id,id AS ancestor_id,0 AS depth FROM ' || tbl_base || '
        UNION ALL 
        SELECT t.id,ancestor_id,depth+1 FROM ' || tbl_base || ' AS t
        JOIN tree ON child_id = ' || fld_parent || '
      )
      SELECT * FROM tree;';
END;
$$;

Closure tables are defined with 3 columns - ANCESTOR_ID, DESCENDANT_ID, DEPTH. It is possible (and I even advice) to store records with same value for ANCESTOR and DESCENDANT, and a value of zero for DEPTH. This will simplify the queries for retrieval of the hierarchy. And they are very simple indeed:

-- get all descendants
SELECT tbl_orig.*,depth FROM tbl_closure LEFT JOIN tbl_orig ON descendant_id = tbl_orig.id WHERE ancestor_id = XXX AND depth <> 0;
-- get only direct descendants
SELECT tbl_orig.* FROM tbl_closure LEFT JOIN tbl_orig ON descendant_id = tbl_orig.id WHERE ancestor_id = XXX AND depth = 1;
-- get all ancestors
SELECT tbl_orig.* FROM tbl_closure LEFT JOIN tbl_orig ON ancestor_id = tbl_orig.id WHERE descendant_id = XXX AND depth <> 0;
-- find the deepest level of children
SELECT MAX(depth) FROM tbl_closure WHERE ancestor_id = XXX;

document.forms will contain an array of forms on your page. You can loop through these forms to find the specific form you desire.

var form = false;
var length = document.forms.length;
for(var i = 0; i < length; i++) {
    if(form.id == "wanted_id") {
        form = document.forms[i];
    }
}

Each form has an elements array which you can then loop through to find the data that you want. You should also be able to access them by name

var wanted_value = form.someFieldName.value;
jsFunction(wanted_value);

Yes the problem is here. It's related to your syntax.

Try using this

return this.http.post(this.BASE_URL, params, options)
  .map(data => this.handleData(data))
  .catch(this.handleError);

instead of

return this.http.post(this.BASE_URL, params, options)
  .map(this.handleData)
  .catch(this.handleError);

Also, the second parameter is supposed to be the body, not the url params.

From the Bootstrap documentation:

Set an element to display: block and center via margin. Available as a mixin and class.

<div class="center-block">...</div>

I solved using a "manual" deserialization. I'll explain in code

public ActionResult MyMethod([System.Web.Http.FromBody] MyModel model)
{
 if (module.Fields == null && !string.IsNullOrEmpty(Request.Form["fields"]))
 {
   model.Fields = JsonConvert.DeserializeObject<MyFieldModel[]>(Request.Form["fields"]);
 }
 //... more code
}

I don't know of a global setting nither but you can try this:

1. Save all Visual Studio templates in UTF-8
2. Write a Visual Studio Macro/Addin that will listen to the DocumentSaved event and will save the file in UTF-8 format (if not already).
3. Put a proxy on your source control that will make sure that new files are always UTF-8.

To print both key and value, use the following:

for (Object objectName : example.keySet()) {
   System.out.println(objectName);
   System.out.println(example.get(objectName));
 }

A more complete answer would be it is not possible with ftp(at least the ftp program installed on centos 6).

Since you wanted an un-attended process, "pts"'s answer will work fine.

Do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

%40 doesn't appear to work.

[~]# ftp domain.com
ftp: connect: Connection refused
ftp> quit
[~]# ftp some_user%[email protected]
ftp: some_user%[email protected]: Name or service not known
ftp> quit

All I've got is to open the ftp program and use the domain and enter the user when asked. Usually, a password is required anyway, so the interactive nature probably isn't problematic.

DWORD is not a C++ type, it's defined in <windows.h>.

The reason is that DWORD has a specific range and format Windows functions rely on, so if you require that specific range use that type. (Or as they say "When in Rome, do as the Romans do.") For you, that happens to correspond to unsigned int, but that might not always be the case. To be safe, use DWORD when a DWORD is expected, regardless of what it may actually be.

For example, if they ever changed the range or format of unsigned int they could use a different type to underly DWORD to keep the same requirements, and all code using DWORD would be none-the-wiser. (Likewise, they could decide DWORD needs to be unsigned long long, change it, and all code using DWORD would be none-the-wiser.)

Also note unsigned int does not necessary have the range 0 to 4,294,967,295. See here.

You can fake a UITextField using UITextView. The problem you'll have is that you lose the place holder functionality.

If you choose to use a UITextView and need the placeholder, do this:

In your viewDidLoad set the color and text to placeholders:

myTxtView.textColor = .lightGray
myTxtView.text = "Type your thoughts here..."

Then make the placeholder disappear when your UITextView is selected:

func textViewDidBeginEditing (textView: UITextView) {
    if myTxtView.textColor.textColor == ph_TextColor && myTxtView.isFirstResponder() {
        myTxtView.text = nil
        myTxtView.textColor = .white
    }
}

When the user finishes editing, ensure there's a value. If there isn't, add the placeholder again:

func textViewDidEndEditing (textView: UITextView) {
    if myTxtView.text.isEmpty || myTxtView.text == "" {
        myTxtView.textColor = .lightGray
        myTxtView.text = "Type your thoughts here..."
    }
}

Other features you might need to fake:

UITextField's often capitalize every letter, you can add that feature to UITableView:

myTxtView.autocapitalizationType = .words

UITextField's don't usually scroll:

myTxtView.scrollEnabled = false

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

try to implement with javascript this:

<div id="mydiv" onclick="myhref('http://web.com');" >some stuff </div>
<script type="text/javascript">
    function myhref(web){
      window.location.href = web;}
</script>

Yes, it's generally bad to call virtual method in the constructor.

At this point, the objet may not be fully constructed yet, and the invariants expected by methods may not hold yet.

It is actually possible only using CSS, however, the image you use to replace must be the same size as the original facebook log in button. Fortunately Facebook delivers the button in different sizes.

From facebook:

size - Different sized buttons: small, medium, large, xlarge - the default is medium. https://developers.facebook.com/docs/reference/plugins/login/

Set the login iframe opacity to 0 and show a background image in the parent div

.fb_iframe_widget iframe {
    opacity: 0;
}

.fb_iframe_widget {
  background-image: url(another-button.png);
  background-repeat: no-repeat;

If you use an image that is bigger than the original facebook button, the part of the image that is outside the width and height of the original button will not be clickable.

To add a file/folder to the project, a good way is:

First of all add your files to /path/to/your/project/my/added/files, and then run following commands:

svn cleanup  /path/to/your/project

svn add --force /path/to/your/project/*

svn cleanup  /path/to/your/project

svn commit /path/to/your/project  -m 'Adding a file'

I used cleanup to prevent any segmentation fault (core dumped), and now the SVN project is updated.

A somewhat cleaner version of one of the other answers is:

val s = Seq("apple", "oranges", "apple", "banana", "apple", "oranges", "oranges")

s.groupBy(identity).mapValues(_.size)

giving a Map with a count for each item in the original sequence:

Map(banana -> 1, oranges -> 3, apple -> 3)

The question asks how to find the count of a specific item. With this approach, the solution would require mapping the desired element to its count value as follows:

s.groupBy(identity).mapValues(_.size)("apple")

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

if you are using maven:

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
</dependency>

And if you don't want to construct an array ...

var str = "how,are you doing, today?";
var res = str.replace(/(.*)([, ])([^, ]*$)/,"$3");

The breakdown in english is:

/(anything)(any separator once)(anything that isn't a separator 0 or more times)/

The replace just says replace the entire string with the stuff after the last separator.

So you can see how this can be applied generally. Note the original string is not modified.

select column1 || ' ' || column2 as whole_name FROM tablename;

Here || is the concat operator used for concatenating them to single column and ('') inside || used for space between two columns.

You can use the Gmail service for the mail.

Steps to use Gmail as an email service (Free) in Django:

1: Create a dummy Google account for your contact. 2: Add the following code in settings.py at the bottom.

 EMAIL_HOST = "smtp.gmail.com"
    EMAIL_PORT = 587
    EMAIL_USE_TLS = True
    EMAIL_HOST_USER = "[email protected]"
    EMAIL_HOST_PASSWORD = "dummypassword"
    
    EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

3: Now in views.py add:

  from django.core.mail import EmailMessage
    # now in your function add this code
    
    messageContent = yourcontent
    msg = EmailMessage(heading, messageContent, settings.EMAIL_HOST_USER,[list of senders email])
    msg.send()

4: Enable these things first for the dummy Gmail account:

a: Go to https://myaccount.google.com/lesssecureapps and enable it. NOTE: First check that you enable this with sign in as your dummy account. b: Now go to https://accounts.google.com/DisplayUnlockCaptcha and click continue.

5: You are ready to use Gmail email services for your contact page.

Bonus:

If you want to send a mail with an HTML template in Django then use this code in views.py.

from django.template.loader import get_template
from django.core.mail import EmailMessage

# add this code in function:
ctx = {
    'subject': subjectin,
    'userMsg': messagein,
   }

heading = Your heading

messageContent = get_template('yourTemplate.html').render(ctx) #sending value on HTML page through context
msg = EmailMessage(heading, messageContent, settings.EMAIL_HOST_USER,
                   [list of emails ])
msg.content_subtype = 'html'
msg.send()

You should never use TortoiseProc.exe as a command-line Subversion client! TortoiseProc should be utilized only for automating TortoiseSVN's GUI. See the note in TortoiseSVN's Manual:

Remember that TortoiseSVN is a GUI client, and this automation guide shows you how to make the TortoiseSVN dialogs appear to collect user input. If you want to write a script which requires no input, you should use the official Subversion command line client instead.

Use the Subversion command-line svn.exe client. With the command-line client, you can

• checkout a working copy in REV revision:

  1. svn checkout --revision REV https://svn.example.com/svn/MyRepo/trunk/

  2. svn checkout https://svn.example.com/svn/MyRepo/trunk/@REV

• update your local working copy to REV revision:

  svn update --revision REV

• export (i.e. download) a file or a development branch in REV revision:

  1. svn export --revision REV https://svn.example.com/svn/MyRepo/trunk/

  2. svn export https://svn.example.com/MyRepo/trunk/@REV

You may notice that with svn checkout and svn export you can enter REV number as --revision REV argument and as trailing @REV after URL. The first one is called operative revision, and the second one is called peg revision. Read SVNBook for more information about peg and operative revisions concept.

You could try:

SELECT name FROM sqlite_master WHERE name='table_name'

An updated version of answer by @Noby Fujioka:

function showPdfInNewTab(base64Data, fileName) {  
  let pdfWindow = window.open("");
  pdfWindow.document.write("<html<head><title>"+fileName+"</title><style>body{margin: 0px;}iframe{border-width: 0px;}</style></head>");
  pdfWindow.document.write("<body><embed width='100%' height='100%' src='data:application/pdf;base64, " + encodeURI(base64Data)+"#toolbar=0&navpanes=0&scrollbar=0'></embed></body></html>");
}

For linux, I wrote a script called find_port.py which you can find here: https://github.com/dhylands/usb-ser-mon/blob/master/usb_ser_mon/find_port.py

It uses pyudev to enumerate all tty devices, and can match on various attributes.

Use the --list option to show all of the know USB serial ports and their attributes. You can filter by VID, PID, serial number, or vendor name. Use --help to see the filtering options.

find_port.py prints the /dev/ttyXXX name rather than the /dev/usb/... name.

if you have an object you can define it as @property so you can get results without a call, e.g.

class Item:
    @property
    def results(self):
        return something

then in the template:

<% for result in item.results %>
...
<% endfor %>

Use Number from the numbers module to test isinstance(n, Number) (available since 2.6).

isinstance(n, numbers.Number)

Here it is in action with various kinds of numbers and one non-number:

>>> from numbers import Number
... from decimal import Decimal
... from fractions import Fraction
... for n in [2, 2.0, Decimal('2.0'), complex(2,0), Fraction(2,1), '2']:
...     print '%15s %s' % (n.__repr__(), isinstance(n, Number))
              2 True
            2.0 True
 Decimal('2.0') True
         (2+0j) True
 Fraction(2, 1) True
            '2' False

This is, of course, contrary to duck typing. If you are more concerned about how an object acts rather than what it is, perform your operations as if you have a number and use exceptions to tell you otherwise.

Try this:

DEMO

<div class="container-fluid"> <!-- If Needed Left and Right Padding in 'md' and 'lg' screen means use container class -->
            <div class="row">
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <a href="#">About</a>
                </div>
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <img src="image.png" />
                </div>
                <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">
                    <a href="#myModal1" data-toggle="modal">SHARE</a>
                </div>
            </div>
        </div>

This code also works:

this.formGroup.controls.nameOfcontrol.value

Here's an utility function that I wrote to wrap the retry until success into a neater package. It uses the same basic structure, but prevents repetition. It could be modified to catch and rethrow the exception on the final try relatively easily.

def try_until(func, max_tries, sleep_time):
    for _ in range(0,max_tries):
        try:
            return func()
        except:
            sleep(sleep_time)
    raise WellNamedException()
    #could be 'return sensibleDefaultValue'

Can then be called like this

result = try_until(my_function, 100, 1000)

If you need to pass arguments to my_function, you can either do this by having try_until forward the arguments, or by wrapping it in a no argument lambda:

result = try_until(lambda : my_function(x,y,z), 100, 1000)

If I've understood your problem correctly, there are two possible problems here:

• resultset is null - I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.
• The second problem is that resultset.getString(i++) will get columns 1,2,3 and so on from each subsequent row.

I think that the second point is probably your problem here.

Lets say you only had 1 row returned, as follows:

Col 1, Col 2, Col 3 
A    ,     B,     C

Your code as it stands would only get A - it wouldn't get the rest of the columns.

I suggest you change your code as follows:

ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>(); 
while (resultset.next()) {                      
    int i = 1;
    while(i <= numberOfColumns) {
        arrayList.add(resultset.getString(i++));
    }
    System.out.println(resultset.getString("Col 1"));
    System.out.println(resultset.getString("Col 2"));
    System.out.println(resultset.getString("Col 3"));                    
    System.out.println(resultset.getString("Col n"));
}

Edit:

To get the number of columns:

ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();

for those looking for a way to mock POST HttpServletRequest with Json payload, the below is in Kotlin, but the key take away here is the DelegatingServetInputStream when you want to mock the request.getInputStream from the HttpServletRequest

@Mock
private lateinit var request: HttpServletRequest

@Mock
private lateinit var response: HttpServletResponse

@Mock
private lateinit var chain: FilterChain

@InjectMocks
private lateinit var filter: ValidationFilter


@Test
fun `continue filter chain with valid json payload`() {
    val payload = """{
      "firstName":"aB",
      "middleName":"asdadsa",
      "lastName":"asdsada",
      "dob":null,
      "gender":"male"
    }""".trimMargin()

    whenever(request.requestURL).
        thenReturn(StringBuffer("/profile/personal-details"))
    whenever(request.method).
        thenReturn("PUT")
    whenever(request.inputStream).
        thenReturn(DelegatingServletInputStream(ByteArrayInputStream(payload.toByteArray())))

    filter.doFilter(request, response, chain)

    verify(chain).doFilter(request, response)
}

You just need to replace all image network paths to byte strings in HTML string. For this first you required HtmlAgilityPack to convert Html string to Html document. https://www.nuget.org/packages/HtmlAgilityPack

Find Below code to convert each image src network path(or local path) to byte sting. It will definitely display all images with network path(or local path) in IE,chrome and firefox.

string encodedHtmlString = Emailmodel.DtEmailFields.Rows[0]["Body"].ToString();

        // Decode the encoded string.
        StringWriter myWriter = new StringWriter();
        HttpUtility.HtmlDecode(encodedHtmlString, myWriter);
        string DecodedHtmlString = myWriter.ToString();

        //find and replace each img src with byte string
         HtmlDocument document = new HtmlDocument();
         document.LoadHtml(DecodedHtmlString);
         document.DocumentNode.Descendants("img")
          .Where(e =>
        {
            string src = e.GetAttributeValue("src", null) ?? "";
            return !string.IsNullOrEmpty(src);//&& src.StartsWith("data:image");
        })
        .ToList()
                    .ForEach(x =>
                    {
                        string currentSrcValue = x.GetAttributeValue("src", null);                                
                        string filePath = Path.GetDirectoryName(currentSrcValue) + "\\";
                        string filename = Path.GetFileName(currentSrcValue);
                        string contenttype = "image/" + Path.GetExtension(filename).Replace(".", "");
                        FileStream fs = new FileStream(filePath + filename, FileMode.Open, FileAccess.Read);
                        BinaryReader br = new BinaryReader(fs);
                        Byte[] bytes = br.ReadBytes((Int32)fs.Length);
                        br.Close();
                        fs.Close();
                        x.SetAttributeValue("src", "data:" + contenttype + ";base64," + Convert.ToBase64String(bytes));                                
                    });

        string result = document.DocumentNode.OuterHtml;
        //Encode HTML string
        string myEncodedString = HttpUtility.HtmlEncode(result);

        Emailmodel.DtEmailFields.Rows[0]["Body"] = myEncodedString;

CONVERT(DATA_TYPE , Your_Column) is the syntax for CONVERT method in SQL. From this convert function we can convert the data of the Column which is on the right side of the comma (,) to the data type in the left side of the comma (,) Please see below example.

SELECT CONVERT (VARCHAR(10), ColumnName) FROM TableName

add an ALIAS on the subquery,

SELECT  COUNT(made_only_recharge) AS made_only_recharge
FROM    
    (
        SELECT DISTINCT (identifiant) AS made_only_recharge
        FROM cdr_data
        WHERE CALLEDNUMBER = '0130'
        EXCEPT
        SELECT DISTINCT (identifiant) AS made_only_recharge
        FROM cdr_data
        WHERE CALLEDNUMBER != '0130'
    ) AS derivedTable                           -- <<== HERE

Maximum is 2097151, If you try set more error occurred.

The C compiler can glue adjacent string literals into one, like

printf("foo: %s "
       "bar: %d", foo, bar);

The preprocessor can use a backslash as a last character of the line, not counting CR (or CR/LF, if you are from Windowsland):

printf("foo %s \
bar: %d", foo, bar);

SELECT  *
FROM    mytable
ORDER BY
        column1 DESC, column2 ASC

Here is how I do custom CSS for Internet Explorer:

In my JavaScript file:

function isIE () {
      var myNav = navigator.userAgent.toLowerCase();
      return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

jQuery(document).ready(function(){
    if(var_isIE){
            if(var_isIE == 10){
                jQuery("html").addClass("ie10");
            }
            if(var_isIE == 8){
                jQuery("html").addClass("ie8");
                // you can also call here some function to disable things that 
                //are not supported in IE, or override browser default styles.
            }
        }
    });

And then in my CSS file, y define each different style:

.ie10 .some-class span{
    .......
}
.ie8 .some-class span{
    .......
}

Lessons to learn from this:

1) Guid is a value type, not a reference type.

2) Calling the default constructor new S() on any value type always gives you back the all-zero form of that value type, whatever it is. It is logically the same as default(S).

The docs for Google Test 1.7 suggest:

"If you have a broken test that you cannot fix right away, you can add the DISABLED_ prefix to its name. This will exclude it from execution."

Examples:

// Tests that Foo does Abc.
TEST(FooTest, DISABLED_DoesAbc) { ... }

class DISABLED_BarTest : public ::testing::Test { ... };

// Tests that Bar does Xyz.
TEST_F(DISABLED_BarTest, DoesXyz) { ... }

I assume that motifWidth contains an integer.

In Python, lists do not change size unless you tell them to. Hence, Python throws an exception when you try to change an element that isn't there. I believe you want:

weightMatrix = []
for k in range(motifWidth):
    weightMatrix.append({'A':0,'C':0,'G':0,'T':0})

For what it's worth, when asking questions in the future, it would help if you included the stack trace showing the error that you're getting rather than just saying "it isn't working". That would help us directly figure out the cause of the problem, rather than trying to puzzle it out from your code.

Hope that helps!

Every time you use html syntax you have to start the next razor statement with a @. So it should be @if ....

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

In your code sample you are trying to divide an integer with another integer. This is the cause of all your trouble. Here is an article that might find interesting on that subject.

With the notion of integer division you can see right away that this is not what you want in your formula. Instead, you need to use some floating point literals.

I am a rather confused by the title of this thread and your code sample. Do you want to convert Celsius degrees to Fahrenheit or do the opposite?

I will base my code sample on your own code sample until you give more details on what you want.

Here is an example of what you can do :

#include <iostream>
//no need to use the whole std namespace... use what you need :)                        
using std::cout;
using std::cin;
using std::endl;                      

int main() 
{   
    //Variables                           
    float celsius,    //represents the temperature in Celsius degrees
          fahrenheit; //represents the converted temperature in Fahrenheit degrees

    //Ask for the temperature in Celsius degrees
    cout << "Enter Celsius temperature: "; 
    cin >> celsius;

    //Formula to convert degrees in Celsius to Fahrenheit degrees
    //Important note: floating point literals need to have the '.0'!
    fahrenheit = celsius * 9.0/5.0 + 32.0;

    //Print the converted temperature to the console
    cout << "Fahrenheit = " << fahrenheit << endl;                            
}

I know this question is really old but I would just like to add my take on partial classes.

One reason that I personally use partial classes is when I'm creating bindings for a program, especially state machines.

For example, OpenGL is a state machine, there are heaps of methods that can all be changed globally, however, in my experience binding something similar to OpenGL where there are so many methods, the class can easily exceed 10k LOC.

Partial classes will break this down for me and help me with finding methods quickly.

if your intention is copy/paste comments for git commits, try set the enviromental variable EDITOR as your favorite plain-text editor (notepad, notepad++ ...) and when you will commit, don't give him the -m option and Git will open your favorite editor for copy/paste you comment

It's very easy. Try the below code

$(document).ready(function(){
  var hashValue = location.hash.replace(/^#/, '');  
  //do something with the value here  
});

Another code swift3

let myLabel = UILabel()
    myLabel.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
    myLabel.center = CGPoint(x: 0, y: 0)
    myLabel.textAlignment = .center
    myLabel.text = "myLabel!!!!!"
    self.view.addSubview(myLabel)

Kotlin Answer

for ((key, value) in map.entries) {
    // do something with `key`
    // so something with `value`
}

You may find other solutions that include filterValues. Just keep in mind that retrieving a Key value using filterValues will include braces [].

val key = map.filterValues {it = position}.keys

The helper methods from the accepted answer are not needed. Streams can be used with lambdas or usually shortened using Method References. Streams enable functional operations. map() converts the elements and collect(...) or toArray() wrap the stream back up into an array or collection.

Venkat Subramaniam's talk (video) explains it better than me.

1 Convert List<String> to List<Integer>

List<String> l1 = Arrays.asList("1", "2", "3");
List<Integer> r1 = l1.stream().map(Integer::parseInt).collect(Collectors.toList());

// the longer full lambda version:
List<Integer> r1 = l1.stream().map(s -> Integer.parseInt(s)).collect(Collectors.toList());

2 Convert List<String> to int[]

int[] r2 = l1.stream().mapToInt(Integer::parseInt).toArray();

3 Convert String[] to List<Integer>

String[] a1 = {"4", "5", "6"};
List<Integer> r3 = Stream.of(a1).map(Integer::parseInt).collect(Collectors.toList());

4 Convert String[] to int[]

int[] r4 = Stream.of(a1).mapToInt(Integer::parseInt).toArray();

5 Convert String[] to List<Double>

List<Double> r5 = Stream.of(a1).map(Double::parseDouble).collect(Collectors.toList());

6 (bonus) Convert int[] to String[]

int[] a2 = {7, 8, 9};
String[] r6 = Arrays.stream(a2).mapToObj(Integer::toString).toArray(String[]::new);

Lots more variations are possible of course.

Also see Ideone version of these examples. Can click fork and then run to run in the browser.

For me this work for example here what happen is the main menu will be disabled when you open the registration form.

 frmUserRegistration frmMainMenu = new frmUserRegistration();
    frmMainMenu.ShowDialog(this);

Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.

DataGridView1.Columns[0].Width=100;// The id column 
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining 
//space

You can use the unicode of a non breaking space :

p:before { content: "\00a0 "; }

You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking

In [17]: df = DataFrame(randn(20,4),columns=list('ABCD'))

In [18]: df[(df['A']>0) & (df['B']>0) & (df['C']>0)]
Out[18]:

In PowerShell, the "sc" command is an alias for the Set-Content cmdlet. You can workaround this using the following syntax:

sc.exe config Service obj= user password= pass

Specyfying the .exe extension, PowerShell bypasses the alias lookup.

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

Note: Use CSS counters to create nested numbering in a modern browser. See the accepted answer. The following is for historical interest only.

If the browser supports content and counter,

.foo {_x000D_
  counter-reset: foo;_x000D_
}_x000D_
.foo li {_x000D_
  list-style-type: none;_x000D_
}_x000D_
.foo li::before {_x000D_
  counter-increment: foo;_x000D_
  content: "1." counter(foo) " ";_x000D_
}

<ol class="foo">_x000D_
  <li>uno</li>_x000D_
  <li>dos</li>_x000D_
  <li>tres</li>_x000D_
  <li>cuatro</li>_x000D_
</ol>

You can put this somewhere global in your code:

$.prototype.enable = function () {
    $.each(this, function (index, el) {
        $(el).removeAttr('disabled');
    });
}

$.prototype.disable = function () {
    $.each(this, function (index, el) {
        $(el).attr('disabled', 'disabled');
    });
}

And then you can write stuff like:

$(".myInputs").enable();
$("#otherInput").disable();

options = webdriver.ChromeOptions()
options.add_argument('--disable-logging')

# Update your desired_capabilities dict withe extra options.
desired_capabilities.update(options.to_capabilities())
driver = webdriver.Remote(desired_capabilities=options.to_capabilities())

Both the desired_capabilities and options.to_capabilities() are dictionaries. You can use the dict.update() method to add the options to the main set.

Using dis to look at the bytecode generated for the two versions:

not ==

  4           0 LOAD_FAST                0 (foo)
              3 LOAD_FAST                1 (bar)
              6 COMPARE_OP               2 (==)
              9 UNARY_NOT           
             10 RETURN_VALUE   

!=

  4           0 LOAD_FAST                0 (foo)
              3 LOAD_FAST                1 (bar)
              6 COMPARE_OP               3 (!=)
              9 RETURN_VALUE   

The latter has fewer operations, and is therefore likely to be slightly more efficient.

It was pointed out in the commments (thanks, @Quincunx) that where you have if foo != bar vs. if not foo == bar the number of operations is exactly the same, it's just that the COMPARE_OP changes and POP_JUMP_IF_TRUE switches to POP_JUMP_IF_FALSE:

not ==:

  2           0 LOAD_FAST                0 (foo)
              3 LOAD_FAST                1 (bar)
              6 COMPARE_OP               2 (==)
              9 POP_JUMP_IF_TRUE        16

!=

  2           0 LOAD_FAST                0 (foo)
              3 LOAD_FAST                1 (bar)
              6 COMPARE_OP               3 (!=)
              9 POP_JUMP_IF_FALSE       16

In this case, unless there was a difference in the amount of work required for each comparison, it's unlikely you'd see any performance difference at all.

However, note that the two versions won't always be logically identical, as it will depend on the implementations of __eq__ and __ne__ for the objects in question. Per the data model documentation:

There are no implied relationships among the comparison operators. The truth of x==y does not imply that x!=y is false.

For example:

>>> class Dummy(object):
    def __eq__(self, other):
        return True
    def __ne__(self, other):
        return True


>>> not Dummy() == Dummy()
False
>>> Dummy() != Dummy()
True

Finally, and perhaps most importantly: in general, where the two are logically identical, x != y is much more readable than not x == y.

INSERT INTO preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,
uploader_id,is_deleted,last_updated) 

SELECT '4827499',pre_image_status,file_extension,reviewer_id,
uploader_id,'0',last_updated FROM preliminary_image WHERE style_id=4827488

Analysis

We can use above query if we want to copy data from one table to another table in mysql

1. Here source and destination table are same, we can use different tables also.
2. Few columns we are not copying like style_id and is_deleted so we selected them hard coded from another table
3. Table we used in source also contains auto increment field so we left that column and it get inserted automatically with execution of query.

Execution results

1 queries executed, 1 success, 0 errors, 0 warnings

Query: insert into preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,uploader_id,is_deleted,last_updated) select ...

5 row(s) affected

setSelectedItem("banana"). You could have found it yourself by just reading the javadoc.

Edit: since you changed the question, I'll change my answer.

If you want to select the item having the "banana" label, then you have two solutions:

1. Iterate through the items to find the one (or the index of the one) which has the given label, and then call setSelectedItem(theFoundItem) (or setSelectedIndex(theFoundIndex))
2. Override equals and hashCode in ComboItem so that two ComboItem instances having the same name are equal, and simply use setSelectedItem(new ComboItem(anyNumber, "banana"));

Note need root than:

• adb root
• adb pull /data/data/com.google.android.apps.nexuslauncher/databases/launcher.db launcher.db

Using sshpass works best. To just include your password in scp use the ' ':

scp user1:'password'@xxx.xxx.x.5:sys_config /var/www/dev/

Highlight "B1" and press F4. This will lock the cell.

Now you can drag it around and it will not change. The principle is simple. It adds a dollar sign before both coordinates. A dollar sign in front of a coordinate will lock it when you copy the formula around. You can have partially locked coordinates and fully locked coordinates.

You could use Regex to determine if there's a whitespace character. \s.

As Kristian Glass Said, there is no comparison between IaaS(AWS) and PaaS(Heroku, EngineYard).

PaaS basically helps developers to speed the development of app,thereby saving money and most importantly innovating their applications and business instead of setting up configurations and managing things like servers and databases. Other features buying to use PaaS is the application deployment process such as agility, High Availability, Monitoring, Scale / Descale, limited need for expertise, easy deployment, and reduced cost and development time.

But still there is a dark side to PaaS which lead barrier to PaaS adoption :

• Less Control over Server and databases
• Costs will be very high if not governed properly
• Premature and dubious in current day and age

Apart from above you should have enough skill set to mange you IaaS:

• Hardware acquisition
• Operating System
• Server Software
• Server Side Scripting Environment
• Web server
• Database Management System(Mysql, Redis etc)
• Configure production server
• Tool for testing and deployment
• Monitoring App
• High Availability
• Load Blancing/ Http Routing
• Service Backup Policies
• Team Collaboration
• Rebuild Production

If you have small scale business, PaaS will be best option for you:

• Pay as you Go
• Low start up cost
• Leave the plumbing to expert
• PaaS handles auto scaling/descaling, Load balancing, disaster recovery
• PaaS manages all security requirements
• PaaS manages reliability, High Availability
• Paas manages many third party add-ons for you

It will be totally individual choice based on requirement. You can have details on my PPT Hosting Rails Apps.

The command you are looking for is git clean

This is not a precise answer for the question but may help in finding a workaround for it.

I had an image I was hiding on page load and displaying when waiting on an AJAX call then hiding again however...

I found the only way to display my image when loading the page then make it disappear and be able to click things where the image was located before hiding it was to put the image into a DIV, make the size of the DIV 10x10 pixels or small enough to prevent it causing an issue then hiding the containing div. This allowed the image to overflow the div while visible and when the div was hidden, only the divs area was affected by inability to click objects beneath and not the whole size of the image the DIV contained and was displaying.

I tried all the methods to hide the image including CSS display=none/block, opacity=0, hiding the image with hidden=true. All of them resulted in my image being hidden but the area where it was displayed to act like there was a cover over the stuff underneath so clicks and so on wouldn't act on the underlying objects. Once the image was inside a tiny DIV and I hid the tiny DIV, the entire area occupied by the image was clear and only the tiny area under the DIV I hid was affected but as I made it small enough (10x10 pixels), the issue was fixed (sort of).

I found this to be a dirty workaround for what should be a simple issue but I was not able to find any way to hide the object in its native format without a container. My object was in the form of etc. If anyone has a better way, please let me know.

I needed a slightly different result.

I wanted the first word, and what ever came after it - even if it was blank.

str.substr(0, text.indexOf(' ') == -1 ? text.length : text.indexOf(' '));
str.substr(text.indexOf(' ') == -1 ? text.length : text.indexOf(' ') + 1);

so if the input is oneword you get oneword and ''.

If the input is one word and some more you get one and word and some more.

You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.

To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)

egrep '(vmx|svm)' /proc/cpuinfo

To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

The issue with

List<String> list = new LinkedList();

is that on the left hand side, you are using the generic type List<String> where on the right side you are using the raw type LinkedList. Raw types in Java effectively only exist for compatibility with pre-generics code and should never be used in new code unless you absolutely have to.

Now, if Java had generics from the beginning and didn't have types, such as LinkedList, that were originally created before it had generics, it probably could have made it so that the constructor for a generic type automatically infers its type parameters from the left-hand side of the assignment if possible. But it didn't, and it must treat raw types and generic types differently for backwards compatibility. That leaves them needing to make a slightly different, but equally convenient, way of declaring a new instance of a generic object without having to repeat its type parameters... the diamond operator.

As far as your original example of List<String> list = new LinkedList(), the compiler generates a warning for that assignment because it must. Consider this:

List<String> strings = ... // some list that contains some strings

// Totally legal since you used the raw type and lost all type checking!
List<Integer> integers = new LinkedList(strings);

Generics exist to provide compile-time protection against doing the wrong thing. In the above example, using the raw type means you don't get this protection and will get an error at runtime. This is why you should not use raw types.

// Not legal since the right side is actually generic!
List<Integer> integers = new LinkedList<>(strings);

The diamond operator, however, allows the right hand side of the assignment to be defined as a true generic instance with the same type parameters as the left side... without having to type those parameters again. It allows you to keep the safety of generics with almost the same effort as using the raw type.

I think the key thing to understand is that raw types (with no <>) cannot be treated the same as generic types. When you declare a raw type, you get none of the benefits and type checking of generics. You also have to keep in mind that generics are a general purpose part of the Java language... they don't just apply to the no-arg constructors of Collections!

4. Import into java class

That should be (see the docs):

In the Html

<div id="AssignUniqueId" runat="server">.....BLAH......<div/>

In the code

public void Page_Load(object source, Event Args e)
{

   if(Session["Something"] == "ShowDiv")
      AssignUniqueId.Visible = true;
    else
      AssignUniqueID.Visible = false;
}

If expression returns a boolean, you can just return the result of it.

Example

 return (a > b)

Another working example in VB.NET:

Public Function base64Encode(ByVal myDataToEncode As String) As String
    Try
        Dim myEncodeData_byte As Byte() = New Byte(myDataToEncode.Length - 1) {}
        myEncodeData_byte = System.Text.Encoding.UTF8.GetBytes(myDataToEncode)
        Dim myEncodedData As String = Convert.ToBase64String(myEncodeData_byte)
        Return myEncodedData
    Catch ex As Exception
        Throw (New Exception("Error in base64Encode" & ex.Message))
    End Try
    '
End Function

If you have a text as

var sampleText ="ä_öü_ßÄ_ TESTED Ö_Ü!@#$%^&())(&&++===.XYZ"

To replace all special character (!@#$%^&())(&&++= ==.) without replacing the characters(including umlaut)

Use below regex

sampleText = sampleText.replace(/[`~!@#$%^&*()|+-=?;:'",.<>{}[]\/\s]/gi,'');

OUTPUT : sampleText = "ä_öü_ßÄ____TESTED_Ö_Ü_____________________XYZ"

This would replace all with an underscore which is provided as second argument to the replace function.You can add whatever you want as per your requirement

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

You can do it in a shorthand as:

_.uniq(foo, 'a')

I agree with the other answers. You cannot rely on the ordering of JSON elements.

However if we need to have an ordered JSON, one solution might be to prepare a LinkedHashMap object with elements and convert it to JSONObject.

@Test
def void testOrdered() {
    Map obj = new LinkedHashMap()
    obj.put("a", "foo1")
    obj.put("b", new Integer(100))
    obj.put("c", new Double(1000.21))
    obj.put("d", new Boolean(true))
    obj.put("e", "foo2")
    obj.put("f", "foo3")
    obj.put("g", "foo4")
    obj.put("h", "foo5")
    obj.put("x", null)

    JSONObject json = (JSONObject) obj
    logger.info("Ordered Json : %s", json.toString())

    String expectedJsonString = """{"a":"foo1","b":100,"c":1000.21,"d":true,"e":"foo2","f":"foo3","g":"foo4","h":"foo5"}"""
    assertEquals(expectedJsonString, json.toString())
    JSONAssert.assertEquals(JSONSerializer.toJSON(expectedJsonString), json)
}

Normally the order is not preserved as below.

@Test
def void testUnordered() {
    Map obj = new HashMap()
    obj.put("a", "foo1")
    obj.put("b", new Integer(100))
    obj.put("c", new Double(1000.21))
    obj.put("d", new Boolean(true))
    obj.put("e", "foo2")
    obj.put("f", "foo3")
    obj.put("g", "foo4")
    obj.put("h", "foo5")
    obj.put("x", null)

    JSONObject json = (JSONObject) obj
    logger.info("Unordered Json : %s", json.toString(3, 3))

    String unexpectedJsonString = """{"a":"foo1","b":100,"c":1000.21,"d":true,"e":"foo2","f":"foo3","g":"foo4","h":"foo5"}"""

    // string representation of json objects are different
    assertFalse(unexpectedJsonString.equals(json.toString()))
    // json objects are equal
    JSONAssert.assertEquals(JSONSerializer.toJSON(unexpectedJsonString), json)
}

You may check my post too: http://www.flyingtomoon.com/2011/04/preserving-order-in-json.html

WebClient to fetch the contents from the remote url and JavaScriptSerializer or Json.NET to deserialize the JSON into a .NET object. For example you define a model class which will reflect the JSON structure and then:

using (var client = new WebClient())
{
    var json = client.DownloadString("http://example.com/json");
    var serializer = new JavaScriptSerializer();
    SomeModel model = serializer.Deserialize<SomeModel>(json);
    // TODO: do something with the model
}

There are also some REST client frameworks you may checkout such as RestSharp.

The difference method in Underscore (or its drop-in replacement, Lo-Dash) can do this too:

(R)eturns the values from array that are not present in the other arrays

_.difference([1, 2, 3, 4, 5], [5, 2, 10]);
=> [1, 3, 4]

As with any Underscore function, you could also use it in a more object-oriented style:

_([1, 2, 3, 4, 5]).difference([5, 2, 10]);

DISCLAMER: I'm the author...

I wrote a package that does exactly this, business dates calculations. You can use custom week specification and holidays.

I had this exact problem while working with financial data and didn't find any of the available solutions particularly easy, so I wrote one.

Hope this is useful for other people.
