I have a large app that was having problems uploading to the AppStore using the archive method you will find in XCode 4. The activity indicator kept spinning for hours whether I was trying to validate or distribute, so I created a support ticket to Apple. During that process, I found out you could right click on the .app in your Products folder inside the Project Navigator of XCode, and compress the app to submit using the Application Loader 2.5.1. (aka the old method). Only the Debug - iphoneos folder is accessible this way (for now) and once Apple responded, this is what they had to say:

I'm glad to hear that Application Loader has provided you a viable workaround. Discussing this situation internally, we're not sure that submitting the Debug build will pose too much of a problem (so long as it was signed with the App Store distribution profile, as you mentioned it was). The app will likely be slower as the debug switches are turned on and optimizations are turned off for the Debug configuration, though it will still run. App Review will ultimately determine whether or not that's ok, as I'm not sure that's something they check for. You could try reaching out directly to App Review to confirm this, if you wish. However, since App Loader is working for you, I do recommend rebuilding the app with your Release configuration and resubmitting to play it safe. To find your Release build in Xcode 4.x, control-click on the Application Archive on the Archives tab in the organizer, and choose "Show in Finder." Then, control-click on the .xcarchive file in Finder and choose "Show Package Contents." The release built .app file should be located within the /Products/Applications folder.

This was very helpful information for developers who are having problems with the archive method, and my app is now uploading successfully without any concern that it won't run to the best of it's ability.

You may find an answer with this example : errorbar_demo_features.py

"""
Demo of errorbar function with different ways of specifying error bars.

Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.

N x 1:
    Error varies for each point, but the error values are symmetric (i.e. the
    lower and upper values are equal).

2 x N:
    Error varies for each point, and the lower and upper limits (in that order)
    are different (asymmetric case)

In addition, this example demonstrates how to use log scale with errorbar.
"""
import numpy as np
import matplotlib.pyplot as plt

# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
# error bar values w/ different -/+ errors
lower_error = 0.4 * error
upper_error = error
asymmetric_error = [lower_error, upper_error]

fig, (ax0, ax1) = plt.subplots(nrows=2, sharex=True)
ax0.errorbar(x, y, yerr=error, fmt='-o')
ax0.set_title('variable, symmetric error')

ax1.errorbar(x, y, xerr=asymmetric_error, fmt='o')
ax1.set_title('variable, asymmetric error')
ax1.set_yscale('log')
plt.show()

Which plots this:

boolean turnedOn;
    if(turnedOn)
    {
    //do stuff when the condition is true - i.e, turnedOn is true
    }
    else
    {
    //do stuff when the condition is false - i.e, turnedOn is false
    }

It is possible to print what Python lines are executed (thanks Geo!). This has any number of applications, for example, you could modify it to check when particular functions are called or add something like ## make it only track particular lines.

code.interact takes you into a interactive console

import code; code.interact(local=locals())

If you want to be able to easily access your console history look at: "Can I have a history mechanism like in the shell?" (will have to look down for it).

Auto-complete can be enabled for the interpreter.

foreach (DataTable table in ds.Tables)
{
    foreach (DataRow dr in table.Rows)
    {
        var ParentId=dr["ParentId"].ToString();
    }
}

You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:

#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);

You can also specify a code page, so if your std::string contains UTF-8 chars you can use:

CA2W pszWide(str.c_str(), CP_UTF8);

Very useful but Windows only.

Size of pointer and int is 2 bytes in Turbo C compiler on windows 32 bit machine.

So size of pointer is compiler specific. But generally most of the compilers are implemented to support 4 byte pointer variable in 32 bit and 8 byte pointer variable in 64 bit machine).

So size of pointer is not same in all machines.

I can only imagine of sending a value from the server to the client which is (unchanged) sent back to maintain a kind of a state.

Precisely. In fact, it's still being used for this purpose today because HTTP as we know it today is still, at least fundamentally, a stateless protocol.

This use case was actually first described in HTML 3.2 (I'm surprised HTML 2.0 didn't include such a description):

type=hidden
These fields should not be rendered and provide a means for servers to store state information with a form. This will be passed back to the server when the form is submitted, using the name/value pair defined by the corresponding attributes. This is a work around for the statelessness of HTTP. Another approach is to use HTTP "Cookies".

<input type=hidden name=customerid value="c2415-345-8563">

While it's worth mentioning that HTML 3.2 became a W3C Recommendation only after JavaScript's initial release, it's safe to assume that hidden fields have pretty much always served the same purpose.

I'm using jQuery 3.3.1 and I received the same error, in my case, the URL was an Object vs a string.

What happened was, that I took URL = window.location - which returned an object. Once I've changed it into window.location.href - it worked w/o the e.indexOf error.

Currently, there's no way to exclude more than one transitive dependency at a time, but there is a feature request for this on the Maven JIRA site:

https://issues.apache.org/jira/browse/MNG-2315

Use a different function, like VLOOKUP:

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", VLOOKUP(A1,B:C,2,FALSE))

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

...
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

If you wanna actually just create remote branch without having the local one, you can do it like this:

git push origin HEAD:refs/heads/foo

It pushes whatever is your HEAD to branch foo that did not exist on the remote.

- FOR EF CORE - with using System.ComponentModel.DataAnnotations;

use [Column(TypeName = "decimal(precision, scale)")]

Precision = Total number of characters used

Scale = Total number after the dot. (easy to get confused)

Example:

public class Blog
{
    public int BlogId { get; set; }
    [Column(TypeName = "varchar(200)")]
    public string Url { get; set; }
    [Column(TypeName = "decimal(5, 2)")]
    public decimal Rating { get; set; }
}

In .NET 4.0, the runtime handles certain exceptions raised as Windows Structured Error Handling (SEH) errors as indicators of Corrupted State. These Corrupted State Exceptions (CSE) are not allowed to be caught by your standard managed code. I won't get into the why's or how's here. Read this article about CSE's in the .NET 4.0 Framework:

http://msdn.microsoft.com/en-us/magazine/dd419661.aspx#id0070035

But there is hope. There are a few ways to get around this:

1. Recompile as a .NET 3.5 assembly and run it in .NET 4.0.

2. Add a line to your application's config file under the configuration/runtime element: <legacyCorruptedStateExceptionsPolicy enabled="true|false"/>

3. Decorate the methods you want to catch these exceptions in with the HandleProcessCorruptedStateExceptions attribute. See http://msdn.microsoft.com/en-us/magazine/dd419661.aspx#id0070035 for details.

EDIT

Previously, I referenced a forum post for additional details. But since Microsoft Connect has been retired, here are the additional details in case you're interested:

From Gaurav Khanna, a developer from the Microsoft CLR Team

This behaviour is by design due to a feature of CLR 4.0 called Corrupted State Exceptions. Simply put, managed code shouldnt make an attempt to catch exceptions that indicate corrupted process state and AV is one of them.

He then goes on to reference the documentation on the HandleProcessCorruptedStateExceptionsAttribute and the above article. Suffice to say, it's definitely worth a read if you're considering catching these types of exceptions.

HashMap is an implementation of Map so it's quite the same but has "clone()" method as i see in reference guide))

I don't think it's bad to use any? at all. I use it a lot. It's clear and concise.

However if you are concerned about all nil values throwing it off, then you are really asking if the array has size > 0. In that case, this dead simple extension (NOT optimized, monkey-style) would get you close.

Object.class_eval do

  def size?
    respond_to?(:size) && size > 0
  end

end

> "foo".size?
 => true
> "".size?
 => false
> " ".size?
 => true
> [].size?
 => false
> [11,22].size?
 => true
> [nil].size?
 => true

This is fairly descriptive, logically asking "does this object have a size?". And it's concise, and it doesn't require ActiveSupport. And it's easy to build on.

Some extras to think about:

1. This is not the same as present? from ActiveSupport.
2. You might want a custom version for String, that ignores whitespace (like present? does).
3. You might want the name length? for String or other types where it might be more descriptive.
4. You might want it custom for Integer and other Numeric types, so that a logical zero returns false.

try getTimezoneOffset() of the Date object:

var curdate = new Date()
var offset = curdate.getTimezoneOffset()

This method returns time zone offset in minutes which is the difference between GMT and local time in minutes.

This has really puzzled me for a while but this is what I found in the end.

When you call, sc.close() in first method, it not only closes your scanner but closes your System.in input stream as well. You can verify it by printing its status at very top of the second method as :

    System.out.println(System.in.available());

So, now when you re-instantiate, Scanner in second method, it doesn't find any open System.in stream and hence the exception.

I doubt if there is any way out to reopen System.in because:

public void close() throws IOException --> Closes this input stream and releases any system resources associated with this stream. The general contract of close is that it closes the input stream. A closed stream cannot perform input operations and **cannot be reopened.**

The only good solution for your problem is to initiate the Scanner in your main method, pass that as argument in your two methods, and close it again in your main method e.g.:

main method related code block:

Scanner scanner = new Scanner(System.in);  

// Ask users for quantities 
PromptCustomerQty(customer, ProductList, scanner );

// Ask user for payment method
PromptCustomerPayment(customer, scanner );

//close the scanner 
scanner.close();

Your Methods:

 public static void PromptCustomerQty(Customer customer, 
                             ArrayList<Product> ProductList, Scanner scanner) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }


 public static void PromptCustomerPayment (Customer customer, Scanner sc) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }

Hope this gives you some insight about the failure and possible resolution.

All the answers so far are incorrect. The Registry normally uses port 1099, but you can change it. But that's not the end of the story. Remote objects also use ports, and not necessarily 1099.

If you don't specify a port when exporting, RMI uses a random port. The solution is therefore to specify a port number when exporting. And this is a port that needs opening in the firewall, if any.

• In the case where your remote object extends UnicastRemoteObject, have its constructor call super(port) with some non-zero port number.

• In the case where it doesn't extend UnicastRemoteObject, provide a non-zero port number to UnicastRemoteObject.exportObject().

There are several wrinkles to this.

• If you aren't using socket factories, and you provide a non-zero port number when exporting your first remote object, RMI will automatically share that port with subsequently exported remote objects without specified port numbers, or specifying zero. That first remote object includes a Registry created with LocateRegistry.createRegistry(). So if you create a Registry on port 1099, all other objects exported from that JVM can share port 1099.

• If you are using socket factories, your RMIServerSocketFactory must have a sensible implementation of equals() for port sharing to work, i.e. one that doesn't just rely on object identity via == or Object.equals().

• If either you don't provide a server socket factory, or you do provide one with a sensible equals() method, but not both, you can use the same non-zero explicit port number for all remote objects, e.g. createRegistry(1099) followed by any number of super(1099) or exportObject(..., 1099) calls.

If you're on SQL Server 2005 or up, you can use this FOR XML PATH & STUFF trick:

DECLARE @CodeNameString varchar(100)

SELECT 
   @CodeNameString = STUFF( (SELECT ',' + CodeName 
                             FROM dbo.AccountCodes 
                             ORDER BY Sort
                             FOR XML PATH('')), 
                            1, 1, '')

The FOR XML PATH('') basically concatenates your strings together into one, long XML result (something like ,code1,code2,code3 etc.) and the STUFF puts a "nothing" character at the first character, e.g. wipes out the "superfluous" first comma, to give you the result you're probably looking for.

UPDATE: OK - I understand the comments - if your text in the database table already contains characters like <, > or &, then my current solution will in fact encode those into <, >, and &.

If you have a problem with that XML encoding - then yes, you must look at the solution proposed by @KM which works for those characters, too. One word of warning from me: this approach is a lot more resource and processing intensive - just so you know.

Or get the number of unique values for each column:

df.nunique()

dID    3
hID    5
mID    3
uID    5
dtype: int64

New in pandas 0.20.0 pd.DataFrame.agg

df.agg(['count', 'size', 'nunique'])

         dID  hID  mID  uID
count      8    8    8    8
size       8    8    8    8
nunique    3    5    3    5

You've always been able to do an agg within a groupby. I used stack at the end because I like the presentation better.

df.groupby('mID').agg(['count', 'size', 'nunique']).stack()


             dID  hID  uID
mID                       
A   count      5    5    5
    size       5    5    5
    nunique    3    5    5
B   count      2    2    2
    size       2    2    2
    nunique    2    2    2
C   count      1    1    1
    size       1    1    1
    nunique    1    1    1

You can do something like this:

public void putOverlay(Bitmap bitmap, Bitmap overlay) {
    Canvas canvas = new Canvas(bitmap);
    Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG);
    canvas.drawBitmap(overlay, 0, 0, paint);
} 

The idea is very simple: Once you associate a bitmap with a canvas, you can call any of the canvas' methods to draw over the bitmap.

This will work for bitmaps that have transparency. A bitmap will have transparency, if it has an alpha channel. Look at Bitmap.Config. You'd probably want to use ARGB_8888.

Important: Look at this Android sample for the different ways you can perform drawing. It will help you a lot.

Performance wise (memory-wise, to be exact), Bitmaps are the best objects to use, since they simply wrap a native bitmap. An ImageView is a subclass of View, and a BitmapDrawable holds a Bitmap inside, but it holds many other things as well. But this is an over-simplification. You can suggest a performance-specific scenario for a precise answer.

Be very careful when cloning ArrayLists. Cloning in java is shallow. This means that it will only clone the Arraylist itself and not its members. So if you have an ArrayList X1 and clone it into X2 any change in X2 will also manifest in X1 and vice-versa. When you clone you will only generate a new ArrayList with pointers to the same elements in the original.

Those 'u' characters being appended to an object signifies that the object is encoded in "unicode".

If you want to remove those 'u' chars from your object you can do this:

import json, ast
jdata = ast.literal_eval(json.dumps(jdata)) # Removing uni-code chars

Let's checkout from python shell

>>> import json, ast
>>> jdata = [{u'i': u'imap.gmail.com', u'p': u'aaaa'}, {u'i': u'333imap.com', u'p': u'bbbb'}]
>>> jdata = ast.literal_eval(json.dumps(jdata))
>>> jdata
[{'i': 'imap.gmail.com', 'p': 'aaaa'}, {'i': '333imap.com', 'p': 'bbbb'}]

Option #1: Use ProvidePlugin

Add the ProvidePlugin to the plugins array in both build/webpack.dev.conf.js and build/webpack.prod.conf.js so that jQuery becomes globally available to all your modules:

plugins: [

  // ...

  new webpack.ProvidePlugin({
    $: 'jquery',
    jquery: 'jquery',
    'window.jQuery': 'jquery',
    jQuery: 'jquery'
  })
]

Option #2: Use Expose Loader module for webpack

As @TremendusApps suggests in his answer, add the Expose Loader package:

npm install expose-loader --save-dev

Use in your entry point main.js like this:

import 'expose?$!expose?jQuery!jquery'

// ...

Building workspace is about incremental build of any evolution detected in one of the opened projects in the currently used workspace.

You can also disable it through the menu "Project / Build automatically".

But I would recommend first to check:

• if a Project Clean all / Build result in the same kind of long wait (after disabling this option)
• if you have (this time with building automatically activated) some validation options you could disable to see if they have an influence on the global compilation time (Preferences / Validations, or Preferences / XML / ... if you have WTP installed)
• if a fresh eclipse installation referencing the same workspace (see this eclipse.ini for more) results in the same issue (with building automatically activated)

Note that bug 329657 (open in 2011, in progress in 2014) is about interrupting a (too lengthy) build, instead of cancelling it:

There is an important difference between build interrupt and cancel.

• When a build is cancelled, it typically handles this by discarding incremental build state and letting the next build be a full rebuild. This can be quite expensive in some projects.
  As a user I think I would rather wait for the 5 second incremental build to finish rather than cancel and result in a 30 second rebuild afterwards.

• The idea with interrupt is that a builder could more efficiently handle interrupt by saving its intermediate state and resuming on the next invocation.
  In practice this is hard to implement so the most common boundary is when we check for interrupt before/after calling each builder in the chain.

another way to do this is by going through the intermediate table. I'd express this within the Django ORM like this:

UserZone = User.zones.through

# for a single zone
users_in_zone = User.objects.filter(
  id__in=UserZone.objects.filter(zone=zone1).values('user'))

# for multiple zones
users_in_zones = User.objects.filter(
  id__in=UserZone.objects.filter(zone__in=[zone1, zone2, zone3]).values('user'))

it would be nice if it didn't need the .values('user') specified, but Django (version 3.0.7) seems to need it.

the above code will end up generating SQL that looks something like:

SELECT * FROM users WHERE id IN (SELECT user_id FROM userzones WHERE zone_id IN (1,2,3))

which is nice because it doesn't have any intermediate joins that could cause duplicate users to be returned

Git doesn't store file permissions other than executable scripts. Consider using something like git-cache-meta to save file ownership and permissions.

Git can only store two types of modes: 755 (executable) and 644 (not executable). If your file was 444 git would store it has 644.

You can do this using groupby to group on the column of interest and then apply list to every group:

In [1]: df = pd.DataFrame( {'a':['A','A','B','B','B','C'], 'b':[1,2,5,5,4,6]})
        df

Out[1]: 
   a  b
0  A  1
1  A  2
2  B  5
3  B  5
4  B  4
5  C  6

In [2]: df.groupby('a')['b'].apply(list)
Out[2]: 
a
A       [1, 2]
B    [5, 5, 4]
C          [6]
Name: b, dtype: object

In [3]: df1 = df.groupby('a')['b'].apply(list).reset_index(name='new')
        df1
Out[3]: 
   a        new
0  A     [1, 2]
1  B  [5, 5, 4]
2  C        [6]

I spent four hours trying various permutations & search suggestions.

At last, found this post that worked but not the best solution to change the original code to test it.

1. Tried changing CLASSPATH, to include class libraries, set classpath=JDKbin;JDKlib;JREbin;JRElib;myClassLib;.
2. Changed the current directory to parent directory(package folder) and tired java <packageName>.<className> also tried the java ..\<packageName>.<className>

Neither worked.

However first response alone worked. Thank you so much Abhi!!!

"I found one another common reason. If you create the java file inside a package using IDE like eclipse, you will find the package name on the top of your java file like "package pkgName". If you try to run this file from command prompt, you will get the NoClassDefFoundError error. Remove the package name from the java file and use the commands in the command prompt. Wasted 3 hours for this. -- Abhi"

Curious if there is any other way to make it work without having to change the original code? Thank you!

Solution - I removed the height and width elements of the img and then the alt text worked.

<img src="smiley.gif" alt="Smiley face" width="32" height="32" />

TO

<img src="smiley.gif" alt="Smiley face" />

Thank you all.

Adding the org.springframework.transaction.annotation.Transactional annotation at the class level for the test class fixed the issue for me.

I solved this by executing C:\mongodb\bin\mongod.exe --repair first. Then when I ran MongoDB again by C:\mongodb\bin\mongod.exe, it successfully started.

There are several ways that you can transform data from multiple rows into columns.

Using PIVOT

In SQL Server you can use the PIVOT function to transform the data from rows to columns:

select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
  select value, columnname
  from yourtable
) d
pivot
(
  max(value)
  for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;

See Demo.

Pivot with unknown number of columnnames

If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName) 
                    from yourtable
                    group by ColumnName, id
                    order by id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = N'SELECT ' + @cols + N' from 
             (
                select value, ColumnName
                from yourtable
            ) x
            pivot 
            (
                max(value)
                for ColumnName in (' + @cols + N')
            ) p '

exec sp_executesql @query;

See Demo.

Using an aggregate function

If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:

select
  max(case when columnname = 'FirstName' then value end) Firstname,
  max(case when columnname = 'Amount' then value end) Amount,
  max(case when columnname = 'PostalCode' then value end) PostalCode,
  max(case when columnname = 'LastName' then value end) LastName,
  max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable

See Demo.

Using multiple joins

This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:

select fn.value as FirstName,
  a.value as Amount,
  pc.value as PostalCode,
  ln.value as LastName,
  an.value as AccountNumber
from yourtable fn
left join yourtable a
  on fn.somecol = a.somecol
  and a.columnname = 'Amount'
left join yourtable pc
  on fn.somecol = pc.somecol
  and pc.columnname = 'PostalCode'
left join yourtable ln
  on fn.somecol = ln.somecol
  and ln.columnname = 'LastName'
left join yourtable an
  on fn.somecol = an.somecol
  and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'

To make Scott Thompson's macro more generic:

// String expander
#define MY_STRX(X) #X
#define MY_STR(X) MY_STRX(X)

#define MYSilenceWarning(FLAG, MACRO) \
_Pragma("clang diagnostic push") \
_Pragma(MY_STR(clang diagnostic ignored MY_STR(FLAG))) \
MACRO \
_Pragma("clang diagnostic pop")

Then use it like this:

MYSilenceWarning(-Warc-performSelector-leaks,
[_target performSelector:_action withObject:self];
                )

I wrapped Jsch with some utility methods to make it a bit friendlier and called it

Jscp

Available here: https://github.com/willwarren/jscp

SCP utility to tar a folder, zip it, and scp it somewhere, then unzip it.

Usage:

// create secure context
SecureContext context = new SecureContext("userName", "localhost");

Jscp.exec(context, 
           "src/dir",

           Arrays.asList("logs/log[0-9]*.txt",
           "backups") 
           );

Also includes useful classes - Scp and Exec, and a TarAndGzip, which work in pretty much the same way.

Small correction, unescape and escape are deprecated, so:

function utf8_to_b64( str ) {
    return window.btoa(decodeURIComponent(encodeURIComponent(str)));
}

function b64_to_utf8( str ) {
     return decodeURIComponent(encodeURIComponent(window.atob(str)));
}


function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(encodeURIComponent(window.atob(str)));
}

I had a similar problem - essentially I was getting a NPE in an async task after the user had destroyed the fragment. After researching the problem on Stack Overflow, I adopted the following solution:

volatile boolean running;

public void onActivityCreated (Bundle savedInstanceState) {

    super.onActivityCreated(savedInstanceState);

    running=true;
    ...
    }


public void onDestroy() {
    super.onDestroy();

    running=false;
    ...
}

Then, I check "if running" periodically in my async code. I have stress tested this and I am now unable to "break" my activity. This works perfectly and has the advantage of being simpler than some of the solutions I have seen on SO.

Yes. With gjson all you have to do now is:

bar := gjson.Get(json, "foo.bar")

bar could be a struct property if you like. Also, no maps.

data.table has a really intuitive way of doing this as well:

library(data.table)

sample_fxn = function(x,y,z){
    return((x+y)*z)
}

df = data.table(A = 1:5,B=seq(2,10,2),C = 6:10)
> df
   A  B  C
1: 1  2  6
2: 2  4  7
3: 3  6  8
4: 4  8  9
5: 5 10 10

The := operator can be called within brackets to add a new column using a function

df[,new_column := sample_fxn(A,B,C)]
> df
   A  B  C new_column
1: 1  2  6         18
2: 2  4  7         42
3: 3  6  8         72
4: 4  8  9        108
5: 5 10 10        150

It's also easy to accept constants as arguments as well using this method:

df[,new_column2 := sample_fxn(A,B,2)]

> df
   A  B  C new_column new_column2
1: 1  2  6         18           6
2: 2  4  7         42          12
3: 3  6  8         72          18
4: 4  8  9        108          24
5: 5 10 10        150          30

The best (and easiest) way to copy data from a workbook to another is to use the object model of Excel.

Option Explicit
Sub test()
    Dim wb As Workbook, wb2 As Workbook
    Dim ws As Worksheet
    Dim vFile As Variant

    'Set source workbook
    Set wb = ActiveWorkbook
    'Open the target workbook
    vFile = Application.GetOpenFilename("Excel-files,*.xls", _
        1, "Select One File To Open", , False)
    'if the user didn't select a file, exit sub
    If TypeName(vFile) = "Boolean" Then Exit Sub
    Workbooks.Open vFile
    'Set targetworkbook
    Set wb2 = ActiveWorkbook

    'For instance, copy data from a range in the first workbook to another range in the other workbook
    wb2.Worksheets("Sheet2").Range("C3:D4").Value = wb.Worksheets("Sheet1").Range("A1:B2").Value
End Sub

This code will extract the content between square brackets and parentheses

(?:(?<=\().+?(?=\))|(?<=\[).+?(?=\]))

(?: non capturing group
(?<=\().+?(?=\)) positive lookbehind and lookahead to extract the text between parentheses
| or
(?<=\[).+?(?=\]) positive lookbehind and lookahead to extract the text between square brackets

[I mentioned this in response to the selected answer, but it was suggested to make it more prominent as an answer of its own]

It should be noted that

ENV PATH="/opt/gtk/bin:${PATH}" 

may not be the same as

ENV PATH="/opt/gtk/bin:$PATH" 

The former, with curly brackets, might provide you with the host's PATH. The documentation doesn't suggest this would be the case, but I have observed that it is. This is simple to check just do RUN echo $PATH and compare it to RUN echo ${PATH}

In my case I had virtual dir. When I accessed main WCF Service in main dir it was working fine but accessing WCF service in virtual dir was throwing an error. I had following code in web.config for both main and virtual dir.

    <security>
        <requestFiltering>
            <denyQueryStringSequences>
                <add sequence=".." />
            </denyQueryStringSequences>
        </requestFiltering>
    </security>

by removing from web.config in virtual dir it fixed it.

I see you would want to do this if you wanted to make, say, the whole box of a menu item clickable. I used to insert an 'li' tag in 'a' tags to do this but this seems more valid.

I think depending on which Android Studio version you have, it's important you update your android studio as well, i was becoming frustrated too following everyone's advice but no luck, until i had to upgrade my android version from 1.3 to 1.5, the errors disappeared like magic.

If I understand your question correctly, is it the fact that the required attribute appears to have default behaviour in Safari that's confusing you? If so, see: http://w3c.github.io/html/sec-forms.html#the-required-attribute

required is not a custom attribute in HTML 5. It's defined in the spec, and is used in precisely the way you're presently using it.

EDIT: Well, not precisely. As ms2ger has pointed out, the required attribute is a boolean attribute, and here's what the HTML 5 spec has to say about those:

Note: The values "true" and "false" are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether.

See: http://w3c.github.io/html/infrastructure.html#sec-boolean-attributes

The problem is that System. currentTimeMillis(); returns the number of milliseconds from 1970-01-01T00:00:00Z, but new Date() gives the current local time. Adding the ZONE_OFFSET and DST_OFFSET from the Calendar class gives you the time in UTC.

Calendar rightNow = Calendar.getInstance();

// offset to add since we're not UTC

long offset = rightNow.get(Calendar.ZONE_OFFSET) +
    rightNow.get(Calendar.DST_OFFSET);

long sinceMidnight = (rightNow.getTimeInMillis() + offset) %
    (24 * 60 * 60 * 1000);

System.out.println(sinceMidnight + " milliseconds since midnight");

Found this works in Safari. SVG only colors in with background-color where an element's bounding box covers. So, give it a border (stroke) with a zero pixel boundary. It fills in the whole thing for you with your background-color.

<svg style='stroke-width: 0px; background-color: blue;'> </svg>

$arrDuplicate = array ("","",1,3,"",5);
 foreach(array_unique($arrDuplicate) as $v){
  if($v != "" ){$arrRemoved = $v;  }}
print_r($arrRemoved);

In 2019 using ES6:

const ids = [1, 4, 5],_x000D_
  data = {_x000D_
    records: [{_x000D_
      "empid": 1,_x000D_
      "fname": "X",_x000D_
      "lname": "Y"_x000D_
    }, {_x000D_
      "empid": 2,_x000D_
      "fname": "A",_x000D_
      "lname": "Y"_x000D_
    }, {_x000D_
      "empid": 3,_x000D_
      "fname": "B",_x000D_
      "lname": "Y"_x000D_
    }, {_x000D_
      "empid": 4,_x000D_
      "fname": "C",_x000D_
      "lname": "Y"_x000D_
    }, {_x000D_
      "empid": 5,_x000D_
      "fname": "C",_x000D_
      "lname": "Y"_x000D_
    }]_x000D_
  };_x000D_
_x000D_
_x000D_
data.records = data.records.filter( i => ids.includes( i.empid ) );_x000D_
_x000D_
console.info( data );

you can go:

var cp = require('child_process');

and then:

cp.exec('./myScript.sh', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a command in your $SHELL.
Or go

cp.spawn('./myScript.sh', [args], function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a file WITHOUT a shell.
Or go

cp.execFile();

which is the same as cp.exec() but doesn't look in the $PATH.

You can also go

cp.fork('myJS.js', function(err, stdout, stderr) {
  // handle err, stdout, stderr
});

to run a javascript file with node.js, but in a child process (for big programs).

EDIT

You might also have to access stdin and stdout with event listeners. e.g.:

var child = cp.spawn('./myScript.sh', [args]);
child.stdout.on('data', function(data) {
  // handle stdout as `data`
});

I've combined some of the advice on this page into something that works for me on iOS 5.

First, you have to add the custom font to your project. Then, you need to follow the advice of @iPhoneDev and add the font to your info.plist file.

After you do that, this works:

UIFont *yourCustomFont = [UIFont fontWithName:@"YOUR-CUSTOM-FONT-POSTSCRIPT-NAME" size:14.0];
[yourUILabel setFont:yourCustomFont];

However, you need to know the Postscript name of your font. Just follow @Daniel Wood's advice and press command-i while you're in FontBook.

Then, enjoy your custom font.

If you want your own custom Error Logging you can easily write your own code. I'll give you a snippet from one of my projects.

public void SaveLogFile(object method, Exception exception)
{
    string location = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"\FolderName\";
    try
    {
        //Opens a new file stream which allows asynchronous reading and writing
        using (StreamWriter sw = new StreamWriter(new FileStream(location + @"log.txt", FileMode.Append, FileAccess.Write, FileShare.ReadWrite)))
        {
            //Writes the method name with the exception and writes the exception underneath
            sw.WriteLine(String.Format("{0} ({1}) - Method: {2}", DateTime.Now.ToShortDateString(), DateTime.Now.ToShortTimeString(), method.ToString()));
            sw.WriteLine(exception.ToString()); sw.WriteLine("");
        }
    }
    catch (IOException)
    {
        if (!File.Exists(location + @"log.txt"))
        {
            File.Create(location + @"log.txt");
        }
    }
}

Then to actually write to the error log just write (q being the caught exception)

SaveLogFile(MethodBase.GetCurrentMethod(), `q`);

The MySQL logs are determined by the global variables such as:

• log_error for the error message log;
• general_log_file for the general query log file (if enabled by general_log);
• slow_query_log_file for the slow query log file (if enabled by slow_query_log);

To see the settings and their location, run this shell command:

mysql -se "SHOW VARIABLES" | grep -e log_error -e general_log -e slow_query_log

To print the value of error log, run this command in the terminal:

mysql -e "SELECT @@GLOBAL.log_error"

To read content of the error log file in real time, run:

sudo tail -f $(mysql -Nse "SELECT @@GLOBAL.log_error")

^{Note: Hit Control-C when finish}

When general log is enabled, try:

sudo tail -f $(mysql -Nse "SELECT CONCAT(@@datadir, @@general_log_file)")

To use mysql with the password access, add -p or -pMYPASS parameter. To to keep it remembered, you can configure it in your ~/.my.cnf, e.g.

[client]
user=root
password=root

So it'll be remembered for the next time.

Go to File -> Settings -> Editor -> Auto Import -> Java and make the below things:

Select Insert imports on paste value to All

Do tick mark on Add unambigious imports on the fly option and "Optimize imports on the fly*

Little improvement to reduce approach to make it work with list. Also using data path as string divided by dots instead of array.

def deep_get(dictionary, path):
    keys = path.split('.')
    return reduce(lambda d, key: d[int(key)] if isinstance(d, list) else d.get(key) if d else None, keys, dictionary)

The problem many times occurs with the milliseconds and final microseconds that many times are in 4 or 8 finals. To convert the DATE to ISO 8601 "date(DATE_ISO8601)" these are one of the solutions that works for me:

// In this form it leaves the date as it is without taking the current date as a reference
$dt = new DateTime();
echo $dt->format('Y-m-d\TH:i:s.').substr($dt->format('u'),0,3).'Z';
// return-> 2020-05-14T13:35:55.191Z

// In this form it takes the reference of the current date
echo date('Y-m-d\TH:i:s'.substr((string)microtime(), 1, 4).'\Z');
return-> 2020-05-14T13:35:55.191Z

// Various examples:
$date_in = '2020-05-25 22:12 03.056';
$dt = new DateTime($date_in);
echo $dt->format('Y-m-d\TH:i:s.').substr($dt->format('u'),0,3).'Z';
// return-> 2020-05-25T22:12:03.056Z

//In this form it takes the reference of the current date
echo date('Y-m-d\TH:i:s'.substr((string)microtime(), 1, 4).'\Z',strtotime($date_in));
// return-> 2020-05-25T14:22:05.188Z

Alright, this doesn't apply to the OP's exact situation, but for anyone like myself who comes here facing a similar issue, figure I should throw this out there-- maybe save a headache or two.

If you're using an non-standard "button" to ensure the submit event isn't called:

<form>
  <input type="hidden" name="hide" value="1">
  <a href="#" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

Then, when you try to access this.form in the script, it's going to come up undefined. As I discovered, apparently anchor elements don't have same access to a parent form element the way your standard form elements do.

In such cases, (again, assuming you are intentionally avoiding the submit event for the time-being), you can use a button with type="button"

<form>
  <input type="hidden" name="hide" value="1">
  <button type="button" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

(Addendum 2020: All these years later, I think the more important lesson to take away from this is to check your input. If my function had bothered to check that the argument it received was actually a form element, the problem would have been much easier to catch.)

The best way in my opinion is using google gson library:

        @Override
public String toString() {
    return new GsonBuilder().setPrettyPrinting().create().toJson(this);
}

or apache commons lang reflection way

In case you don't know in advance how many elements you will have to handle it might be a better solution to use collections instead (https://en.wikipedia.org/wiki/Java_collections_framework). It would be possible also to create a new bigger 2-dimensional array, copy the old data over and insert the new items there, but the collection framework handles this for you automatically.

In this case you could use a Map of Strings to Lists of Strings:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class MyClass {
    public static void main(String args[]) {
        Map<String, List<String>> shades = new HashMap<>();

        ArrayList<String> shadesOfGrey = new ArrayList<>();
        shadesOfGrey.add("lightgrey");
        shadesOfGrey.add("dimgray");
        shadesOfGrey.add("sgi gray 92");

        ArrayList<String> shadesOfBlue = new ArrayList<>();
        shadesOfBlue.add("dodgerblue 2");
        shadesOfBlue.add("steelblue 2");
        shadesOfBlue.add("powderblue");

        ArrayList<String> shadesOfYellow = new ArrayList<>();
        shadesOfYellow.add("yellow 1");
        shadesOfYellow.add("gold 1");
        shadesOfYellow.add("darkgoldenrod 1");

        ArrayList<String> shadesOfRed = new ArrayList<>();
        shadesOfRed.add("indianred 1");
        shadesOfRed.add("firebrick 1");
        shadesOfRed.add("maroon 1");

        shades.put("greys", shadesOfGrey);
        shades.put("blues", shadesOfBlue);
        shades.put("yellows", shadesOfYellow);
        shades.put("reds", shadesOfRed);

        System.out.println(shades.get("greys").get(0)); // prints "lightgrey"
    }
}

You may need to do AndroidStudio - Build - Clean

If you updated manifest through the filesystem or Git it won't pick up the changes.

When you declare

public static <T> void foo(List<T>... bar) the compiler converts it to

public static <T> void foo(List<T>[] bar) then to

public static void foo(List[] bar)

The danger then arises that you'll mistakenly assign incorrect values into the list and the compiler will not trigger any error. For example, if T is a String then the following code will compile without error but will fail at runtime:

// First, strip away the array type (arrays allow this kind of upcasting)
Object[] objectArray = bar;

// Next, insert an element with an incorrect type into the array
objectArray[0] = Arrays.asList(new Integer(42));

// Finally, try accessing the original array. A runtime error will occur
// (ClassCastException due to a casting from Integer to String)
T firstElement = bar[0].get(0);

If you reviewed the method to ensure that it doesn't contain such vulnerabilities then you can annotate it with @SafeVarargs to suppress the warning. For interfaces, use @SuppressWarnings("unchecked").

If you get this error message:

Varargs method could cause heap pollution from non-reifiable varargs parameter

and you are sure that your usage is safe then you should use @SuppressWarnings("varargs") instead. See Is @SafeVarargs an appropriate annotation for this method? and https://stackoverflow.com/a/14252221/14731 for a nice explanation of this second kind of error.

Just to add my answer, it seems that the transitions need to be based on initial values and final values within the css properties to be able to manage the animation.

If you decide to use Underscore.js you better do

_.values(ahash)[0]

to get value, or

_.keys(ahash)[0]

to get key.

From the Intel's manual - Instruction Set Reference, the JE and JZ have the same opcode (74 for rel8 / 0F 84 for rel 16/32) also JNE and JNZ (75 for rel8 / 0F 85 for rel 16/32) share opcodes.

JE and JZ they both check for the ZF (or zero flag), although the manual differs slightly in the descriptions of the first JE rel8 and JZ rel8 ZF usage, but basically they are the same.

Here is an extract from the manual's pages 464, 465 and 467.

 Op Code    | mnemonic  | Description
 -----------|-----------|-----------------------------------------------  
 74 cb      | JE rel8   | Jump short if equal (ZF=1).
 74 cb      | JZ rel8   | Jump short if zero (ZF ? 1).

 0F 84 cw   | JE rel16  | Jump near if equal (ZF=1). Not supported in 64-bit mode.
 0F 84 cw   | JZ rel16  | Jump near if 0 (ZF=1). Not supported in 64-bit mode.

 0F 84 cd   | JE rel32  | Jump near if equal (ZF=1).
 0F 84 cd   | JZ rel32  | Jump near if 0 (ZF=1).

 75 cb      | JNE rel8  | Jump short if not equal (ZF=0).
 75 cb      | JNZ rel8  | Jump short if not zero (ZF=0).

 0F 85 cd   | JNE rel32 | Jump near if not equal (ZF=0).
 0F 85 cd   | JNZ rel32 | Jump near if not zero (ZF=0).

This is the one way to remove the last character in the string:

Scanner in = new Scanner(System.in);
String s = in.nextLine();
char array[] = s.toCharArray();
int l = array.length;
for (int i = 0; i < l-1; i++) {
    System.out.print(array[i]);
}

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

A somewhat clumsy ascii-art to demonstrate the mechanism: The join() is presumably called by the main-thread. It could also be called by another thread, but would needlessly complicate the diagram.

join-calling should be placed in the track of the main-thread, but to express thread-relation and keep it as simple as possible, I choose to place it in the child-thread instead.

'#' optional parent-thread execution after join()-blocked parent-thread could 
    continue
'*' main-thread 'sleeping' in join-method, waiting for child-thread to finish
',' daemonized thread - 'ignores' lifetime of other threads;
    terminates when main-programs exits; is normally meant for 
    join-independent tasks

So the reason you don't see any changes is because your main-thread does nothing after your join. You could say join is (only) relevant for the execution-flow of the main-thread.

If, for example, you want to concurrently download a bunch of pages to concatenate them into a single large page, you may start concurrent downloads using threads, but need to wait until the last page/thread is finished before you start assembling a single page out of many. That's when you use join().

set time limit in __construct method or you can set in your index controller also where you want to have large time limit.

public function __construct()
{
    set_time_limit(8000000);
}

Try this:

    public static void main(String[] args)
    {
        Pattern p = Pattern.compile("^\\d+$");
        Scanner kb = new Scanner(System.in);
        int num1;
        int num2 = 0;
        String temp;
        Matcher numberMatcher;
        System.out.print("Enter number 1: ");
        try
        {
            num1 = kb.nextInt();
        }

        catch (java.util.InputMismatchException e)
        {
            System.out.println("Invalid Input");
            //
            return;
        }
        while(num2<num1)
        {
            System.out.print("Enter number 2: ");
            temp = kb.next();
            numberMatcher = p.matcher(temp);
            if (numberMatcher.matches())
            {
                num2 = Integer.parseInt(temp);
            }

            else
            {
                System.out.println("Invalid Number");
            }
        }
    }

You could try to parse the string into an int as well, but usually people try to avoid throwing exceptions.

What I have done is that I have defined a regular expression that defines a number, \d means a numeric digit. The + sign means that there has to be one or more numeric digits. The extra \ in front of the \d is because in java, the \ is a special character, so it has to be escaped.

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

    // process headers using request interceptor
    final Map<String, String> sendHeaders = new HashMap<String, String>();
    if ((headers != null) && (headers.size() > 0)) {
        sendHeaders.putAll(headers);
    }
    if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
        sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
    }
    // request gzip encoding for response
    sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);

    if (sendHeaders.size() > 0) {
        client.addRequestInterceptor(new HttpRequestInterceptor() {

            public void process(final HttpRequest request, final HttpContext context) throws HttpException,
                IOException {
                for (String key : sendHeaders.keySet()) {
                    if (!request.containsHeader(key)) {
                        request.addHeader(key, sendHeaders.get(key));
                    }
                }
            }
        });
    }

    //.... code omitted ....//

The simplest solution is to use option -B or --databases.Then CREATE database command appears in the output file. For example:

mysqldump -uuser -ppassword -d -B --events --routines --triggers database_example > database_example.sql

The LINQ translator is smart enough to execute:

.Where(r => r.UserName !="XXXX" && r.UsernName !="YYYY")

I've test this in LinqPad ==> YES, Linq translator is smart enough :))

From API version 19 it is possible to call ActivityManager.clearApplicationUserData().

((ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE)).clearApplicationUserData();

Looks like Firebug (Firefox add-on) has the answer:

• open Firebug
• right click the element in HTML tab
• click Log Events
• enable Console tab
• click Persist in Console tab (otherwise Console tab will clear after the page is reloaded)
• select Closed (manually)

• there will be something like this in Console tab:

  ...
  mousemove clientX=1097, clientY=292
  popupshowing
  mousedown clientX=1097, clientY=292
  focus
  mouseup clientX=1097, clientY=292
  click clientX=1097, clientY=292
  mousemove clientX=1096, clientY=293
  ...

This worked for me.

Here I assume my attachment is of a PDF type format.

                    }
                });
        try {
            // Create a default MimeMessage object.
            Message message = new MimeMessage(session);
            // Set From: header field of the header.
            message.setFrom(new InternetAddress(from));
            // Set To: header field of the header.
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(to));
            // Set Subject: header field
            message.setSubject("Attachment");
            // Create the message part
            BodyPart messageBodyPart = new MimeBodyPart();
            // Now set the actual message
            messageBodyPart.setText("Please find the attachment below");
            // Create a multipar message
            Multipart multipart = new MimeMultipart();
            // Set text message part
            multipart.addBodyPart(messageBodyPart);
            // Part two is attachment
            messageBodyPart = new MimeBodyPart();
            String filename = "D:/test.PDF";
            DataSource source = new FileDataSource(filename);
            messageBodyPart.setDataHandler(new DataHandler(source));
            messageBodyPart.setFileName(filename);
            multipart.addBodyPart(messageBodyPart);
            // Send the complete message parts
            message.setContent(multipart);
            // Send message
            Transport.send(message);
            System.out.println("Email Sent Successfully !!");
        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }

} 

A common use case where it can be used 'as is' is to override a class just to create a type (which is otherwise the same as the superclass), e.g.

class Error(Exception):
    pass

So you can raise and catch Error exceptions. What matters here is the type of exception, rather than the content.

Check target framework in the projects.

In my case "You must add a reference to assembly" actually meant, that caller and reference projects didn't have the same target framework. The caller project had .Net 4.5 , but referenced library had target 4.6.1.

I am sure, that MS compiler can be smarter and log more meaningful error message. I've added a suggestion to https://github.com/dotnet/roslyn/issues/14756

You can create the radio buttons dynamically, ListBox can help you do that, without converters, quite simple.

The concrete steps are below:

• create a ListBox and set the ItemsSource for the listbox as the enum MyLovelyEnum and binding the SelectedItem of the ListBox to the VeryLovelyEnum property.
• then the Radio Buttons for each ListBoxItem will be created.

• Step 1: add the enum to static resources for your Window, UserControl or Grid etc.

    <Window.Resources>
        <ObjectDataProvider MethodName="GetValues"
                            ObjectType="{x:Type system:Enum}"
                            x:Key="MyLovelyEnum">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="local:MyLovelyEnum" />
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
    </Window.Resources>

• Step 2: Use the List Box and Control Template to populate each item inside as Radio button

    <ListBox ItemsSource="{Binding Source={StaticResource MyLovelyEnum}}" SelectedItem="{Binding VeryLovelyEnum, Mode=TwoWay}" >
        <ListBox.Resources>
            <Style TargetType="{x:Type ListBoxItem}">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                            <RadioButton
                                Content="{TemplateBinding ContentPresenter.Content}"
                                IsChecked="{Binding Path=IsSelected,
                                RelativeSource={RelativeSource TemplatedParent},
                                Mode=TwoWay}" />
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ListBox.Resources>
    </ListBox>

The advantage is: if someday your enum class changes, you do not need to update the GUI (XAML file).

For me, javax.persistence.Id should be used instead of org.springframework.data.annotation.Id. For anyone who encountered this issue, you can check if you imported the right Id class.

Like you, I was also looking for a solution which does not include newlines. (While they may be safe in SQL, they're not safe in my case and I have a large block of text to deal with)

This is arguably just as ugly, but you can backslash-escape newlines in a heredoc to omit them from the resulting string:

conn.exec <<~END_OF_INPUT
    select attr1, attr2, attr3, attr4, attr5, attr6, attr7 \
    from table1, table2, table3, etc, etc, etc, etc, etc, \
    where etc etc etc etc etc etc etc etc etc etc etc etc etc
  END_OF_INPUT

Note that you cannot due this without interpolation (I.E. <<~'END_OF_INPUT') so be careful. #{expressions} will be evaluated here, whereas they will not in your original code. A. Wilson's answer may be better for that reason.

Starting with Android 11, you can directly bring up the app-specific settings page for the location permission only using code like this: requestPermissions(arrayOf(Manifest.permission.ACCESS_BACKGROUND_LOCATION), PERMISSION_REQUEST_BACKGROUND_LOCATION)

However, the above will only work one time. If the user denies the permission or even accidentally dismisses the screen, the app can never trigger this to come up again.

Other than the above, the answer remains the same as prior to Android 11 -- the best you can do is bring up the app-specific settings page and ask the user to drill down two levels manually to enable the proper permission.

val intent = Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
val uri: Uri = Uri.fromParts("package", packageName, null)
intent.data = uri
// This will take the user to a page where they have to click twice to drill down to grant the permission
startActivity(intent)

See my related question here: Android 11 users can’t grant background location permission?

Go to folder and use the command:

svn co {url}

I've never actually used this, but try view.getClass().getGenericSuperclass()

In some cases you need to be able to do things like that under a user with sudo (e.g. the application running in the container provides a shell to users). Simply add this into you Dockerfile:

RUN apt-get update         # If necessary
RUN apt-get install sudo   # If your base image does not contain sudo.
RUN useradd -m -N -s /bin/bash -u 1000 -p '$1$miTOHCYy$K.c4Yw.edukWJ7z9rbpTZ0' user && \
    usermod -aG sudo user  # Grant sudo to the user
USER user

Now under the default image user user you will be able to sudo with the password set on line 3.

See how to generate password hash for useradd here or here.

<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');

set nu set ai set tabstop=4 set ls=2 set autoindent

Add the above code in your .vimrc file. if .vimrc file is not present please create in your home directory (/home/name of user)

set nu -> This makes Vim display line numbers

set ai -> This makes Vim enable auto-indentation

set ls=2 -> This makes Vim show a status line

set tabstop=4 -> This makes Vim set tab of length 4 spaces (it is 8 by default)

The filename will also be displayed.

Another simple solution referenced by Visual Studio Forum.

Changing configuration: menu Tools ? Options ? Projects and Solutions ? VC++ Project Settings ? Solution Explorer Mode to Show all files.

Then you can see all files in Solution Explorer.

Find the files marked by the yellow icon and remove them from the project.

It's OK.

Here is a sample using pysftp and a private key.

import pysftp

def upload_file(file_path):

    private_key = "~/.ssh/your-key.pem"  # can use password keyword in Connection instead
    srv = pysftp.Connection(host="your-host", username="user-name", private_key=private_key)
    srv.chdir('/var/web/public_files/media/uploads')  # change directory on remote server
    srv.put(file_path)  # To download a file, replace put with get
    srv.close()  # Close connection

pysftp is an easy to use sftp module that utilizes paramiko and pycrypto. It provides a simple interface to sftp.. Other things that you can do with pysftp which are quite useful:

data = srv.listdir()  # Get the directory and file listing in a list
srv.get(file_path)  # Download a file from remote server
srv.execute('pwd') # Execute a command on the server

ASP.NET Core 3.1

This is my implementation of the feature, it works on server side as well as with jquery validation unobtrusive with a custom error message just like any other attribute:

The attribute:

  [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)]
    public class MustBeIntegerAttribute : ValidationAttribute, IClientModelValidator
    {
        public void AddValidation(ClientModelValidationContext context)
        {
            MergeAttribute(context.Attributes, "data-val", "true");
            var errorMsg = FormatErrorMessage(context.ModelMetadata.GetDisplayName());
            MergeAttribute(context.Attributes, "data-val-mustbeinteger", errorMsg);
        }

        public override bool IsValid(object value)
        {
            return int.TryParse(value?.ToString() ?? "", out int newVal);
        }

        private bool MergeAttribute(
              IDictionary<string, string> attributes,
              string key,
              string value)
        {
            if (attributes.ContainsKey(key))
            {
                return false;
            }
            attributes.Add(key, value);
            return true;
        }
    }

Client side logic:

$.validator.addMethod("mustbeinteger",
    function (value, element, parameters) {
        return !isNaN(parseInt(value)) && isFinite(value);
    });

$.validator.unobtrusive.adapters.add("mustbeinteger", [], function (options) {
    options.rules.mustbeinteger = {};
    options.messages["mustbeinteger"] = options.message;
});

And finally the Usage:

 [MustBeInteger(ErrorMessage = "You must provide a valid number")]
 public int SomeNumber { get; set; }

With Swift 5, according to your needs, you may choose one of the four following Playground code examples in order to solve your problem.

#1. Using ClosedRange reversed() method

ClosedRange has a method called reversed(). reversed() method has the following declaration:

func reversed() -> ReversedCollection<ClosedRange<Bound>>

Returns a view presenting the elements of the collection in reverse order.

Usage:

let reversedCollection = (0 ... 5).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use Range reversed() method:

let reversedCollection = (0 ..< 6).reversed()

for index in reversedCollection {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#2. Using sequence(first:next:) function

Swift Standard Library provides a function called sequence(first:next:). sequence(first:next:) has the following declaration:

func sequence<T>(first: T, next: @escaping (T) -> T?) -> UnfoldFirstSequence<T>

Returns a sequence formed from first and repeated lazy applications of next.

Usage:

let unfoldSequence = sequence(first: 5, next: {
    $0 > 0 ? $0 - 1 : nil
})

for index in unfoldSequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#3. Using stride(from:through:by:) function

Swift Standard Library provides a function called stride(from:through:by:). stride(from:through:by:) has the following declaration:

func stride<T>(from start: T, through end: T, by stride: T.Stride) -> StrideThrough<T> where T : Strideable

Returns a sequence from a starting value toward, and possibly including, an end value, stepping by the specified amount.

Usage:

let sequence = stride(from: 5, through: 0, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

As an alternative, you can use stride(from:to:by:):

let sequence = stride(from: 5, to: -1, by: -1)

for index in sequence {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

#4. Using AnyIterator init(_:) initializer

AnyIterator has an initializer called init(_:). init(_:) has the following declaration:

init(_ body: @escaping () -> AnyIterator<Element>.Element?)

Creates an iterator that wraps the given closure in its next() method.

Usage:

var index = 5

guard index >= 0 else { fatalError("index must be positive or equal to zero") }

let iterator = AnyIterator({ () -> Int? in
    defer { index = index - 1 }
    return index >= 0 ? index : nil
})

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

If needed, you can refactor the previous code by creating an extension method for Int and wrapping your iterator in it:

extension Int {

    func iterateDownTo(_ endIndex: Int) -> AnyIterator<Int> {
        var index = self
        guard index >= endIndex else { fatalError("self must be greater than or equal to endIndex") }

        let iterator = AnyIterator { () -> Int? in
            defer { index = index - 1 }
            return index >= endIndex ? index : nil
        }
        return iterator
    }

}

let iterator = 5.iterateDownTo(0)

for index in iterator {
    print(index)
}

/*
Prints:
5
4
3
2
1
0
*/

To define intersection that correctly takes into account the cardinality of the elements use Counter:

from collections import Counter

>>> c1 = [1, 2, 2, 3, 4, 4, 4]
>>> c2 = [1, 2, 4, 4, 4, 4, 5]
>>> list((Counter(c1) & Counter(c2)).elements())
[1, 2, 4, 4, 4]

For logging purposes, I'm afraid there's no nicer way of doing this but to construct the string yourself:

string query = cmd.CommandText;

foreach (SqlParameter p in cmd.Parameters)
{
    query = query.Replace(p.ParameterName, p.Value.ToString());
}

If you don't care about loading the file into memory, as of Go 1.16, you can use the os.ReadFile and bytes.Count functions.

package main

import (
    "log"
    "os"
    "bytes"
)

func main() {
    data, err := os.ReadFile("input.txt")
    if err != nil {
        log.Fatal(err)
    }

    n := bytes.Count(data, []byte{'\n'})

    fmt.Printf("input.txt has %d lines\n", n)
}

@roman-bodnarchuk list comprehensions function def diff(a, b) seems to be faster.

A work around you can try is defining a getInstance() method in your interface so the implementer is aware of what parameters need to be handled. It isn't as solid as an abstract class, but it allows more flexibility as being an interface.

However this workaround does require you to use the getInstance() to instantiate all objects of this interface.

E.g.

public interface Module {
    Module getInstance(Receiver receiver);
}

... or if you want / need to keep your option 'value' as it was, just add a new attribute:

<select id="my_selection">
<option value="x" href="/link/to/somewhere">value 1</option>
<option value="y" href="/link/to/somewhere/else">value 2</option>
</select>

<script>
document.getElementById('my_selection').onchange = function() {
    window.location.href = this.children[this.selectedIndex].getAttribute('href');
}
</script>

try this code:

.absolute {
    position: absolute;
    top: 0; left: 0;
    width: 200px;
    height: 50px;
    background: yellow;

}

Here's my solution in Javascript - very much like JPot's, but shorter (and possibly a tiny bit faster):

value = new Date(parseInt(value.substr(6)));

"value.substr(6)" takes out the "/Date(" part, and the parseInt function ignores the non-number characters that occur at the end.

EDIT: I have intentionally left out the radix (the 2nd argument to parseInt); see my comment below. Also, please note that ISO-8601 dates are preferred over this old format -- so this format generally shouldn't be used for new development. See the excellent Json.NET library for a great alternative that serializes dates using the ISO-8601 format.

For ISO-8601 formatted JSON dates, just pass the string into the Date constructor:

var date = new Date(jsonDate); //no ugly parsing needed; full timezone support

Ok I'll share this option. This is a pretty performant option - it uses an array internally - and reuses entries. It's thread safe - and you can retrieve the contents as a List.

static class FixedSizeCircularReference<T> {
    T[] entries

    FixedSizeCircularReference(int size) {
        this.entries = new Object[size] as T[]
        this.size = size
    }
    int cur = 0
    int size

    synchronized void add(T entry) {
        entries[cur++] = entry
        if (cur >= size) {
            cur = 0
        }
    }

    List<T> asList() {
        int c = cur
        int s = size
        T[] e = entries.collect() as T[]
        List<T> list = new ArrayList<>()
        int oldest = (c == s - 1) ? 0 : c
        for (int i = 0; i < e.length; i++) {
            def entry = e[oldest + i < s ? oldest + i : oldest + i - s]
            if (entry) list.add(entry)
        }
        return list
    }
}

Essentially:

history.pushState('data', '', 'http://your-domain/path');

You can manipulate the history object to make this work.

It only works on the same domain, but since you're satisfied with using the hash tag approach, that shouldn't matter.

Obviously would need to be cross-browser tested, but since that was posted on the Opera forum I'm safe to assume it would work in Opera, and I just tested it in Chrome and it worked fine.

Hmmm. There was an answer with a list comprehension here, but it's disappeared.

Here:

 [i for i,x in enumerate(testlist) if x == 1]

Example:

>>> testlist
[1, 2, 3, 5, 3, 1, 2, 1, 6]
>>> [i for i,x in enumerate(testlist) if x == 1]
[0, 5, 7]

Update:

Okay, you want a generator expression, we'll have a generator expression. Here's the list comprehension again, in a for loop:

>>> for i in [i for i,x in enumerate(testlist) if x == 1]:
...     print i
... 
0
5
7

Now we'll construct a generator...

>>> (i for i,x in enumerate(testlist) if x == 1)
<generator object at 0x6b508>
>>> for i in (i for i,x in enumerate(testlist) if x == 1):
...     print i
... 
0
5
7

and niftily enough, we can assign that to a variable, and use it from there...

>>> gen = (i for i,x in enumerate(testlist) if x == 1)
>>> for i in gen: print i
... 
0
5
7

And to think I used to write FORTRAN.

Another answer could be to use the tar.gz file instead in the Linux case. There seem to be something like that also for the solaris platform. This way all files will already be in the expected format and there won't be any unpacking issues.

I know it's a bit old question but still people try to find efficient solution so instead you should use FULLTEXT index (it's available from MySQL 5.6.4).

Query on table with +35mil records by triple like in where block took ~2.5s but after adding index on these fields and using BOOLEAN MODE inside match ... against ... it took only 0.05s.

$options['inputs']['name'] = $new_input['name'];

I found a real cool Grid which I also use for columns. Check it out Simple Grid. Wich this CSS you can simply use:

<div class="grid">
    <div class="col-1-2">
       <div class="content">
           <p>...insert content left side...</p>
       </div>
    </div>
    <div class="col-1-2">
       <div class="content">
           <p>...insert content right side...</p>
       </div>
    </div>
</div>

I use it for all my projects.

I had the same issue (same error on heroku, working on local machine) and I tried all the solutions listed here including heroku run rails console which ran without error messages. I tried heroku run rake db:migrate and heroku run rake db:migrate:reset a few times. None of this solved the problem. On going through some files that are used in production but not in dev environment, I found some whitespace in the puma.rb file to be the culprit. Hope this helps someone who has the same issue. Changing this made it work

  ActiveRecord::Base.establish_connection
  End

to

  ActiveRecord::Base.establish_connection
end

I wanted to add one more point is, if you are storing a really large number like 902054990011312 then one can easily see the difference of INT(20) and BIGINT(20). It is advisable to store in BIGINT.

You can declare local variables in MySQL triggers, with the DECLARE syntax.

Here's an example:

DROP TABLE IF EXISTS foo;
CREATE TABLE FOO (
  i SERIAL PRIMARY KEY
);

DELIMITER //
DROP TRIGGER IF EXISTS bar //

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = NEW.i;
  SET @a = x; -- set user variable outside trigger
END//

DELIMITER ;

SET @a = 0;

SELECT @a; -- returns 0

INSERT INTO foo () VALUES ();

SELECT @a; -- returns 1, the value it got during the trigger

When you assign a value to a variable, you must ensure that the query returns only a single value, not a set of rows or a set of columns. For instance, if your query returns a single value in practice, it's okay but as soon as it returns more than one row, you get "ERROR 1242: Subquery returns more than 1 row".

You can use LIMIT or MAX() to make sure that the local variable is set to a single value.

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT age FROM users WHERE name = 'Bill'); 
  -- ERROR 1242 if more than one row with 'Bill'
END//

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT MAX(age) FROM users WHERE name = 'Bill');
  -- OK even when more than one row with 'Bill'
END//

Something like this should work (it did for me). The reason for wanting to use -Filter instead of -Include is that include takes a huge performance hit compared to -Filter.

Below just loops each file type and multiple servers/workstations specified in separate files.

##  
##  This script will pull from a list of workstations in a text file and search for the specified string


## Change the file path below to where your list of target workstations reside
## Change the file path below to where your list of filetypes reside

$filetypes = gc 'pathToListOffiletypes.txt'
$servers = gc 'pathToListOfWorkstations.txt'

##Set the scope of the variable so it has visibility
set-variable -Name searchString -Scope 0
$searchString = 'whatYouAreSearchingFor'

foreach ($server in $servers)
    {

    foreach ($filetype in $filetypes)
    {

    ## below creates the search path.  This could be further improved to exclude the windows directory
    $serverString = "\\"+$server+"\c$\Program Files"


    ## Display the server being queried
    write-host “Server:” $server "searching for " $filetype in $serverString

    Get-ChildItem -Path $serverString -Recurse -Filter $filetype |
    #-Include "*.xml","*.ps1","*.cnf","*.odf","*.conf","*.bat","*.cfg","*.ini","*.config","*.info","*.nfo","*.txt" |
    Select-String -pattern $searchstring | group path | select name | out-file f:\DataCentre\String_Results.txt

    $os = gwmi win32_operatingsystem -computer $server
    $sp = $os | % {$_.servicepackmajorversion}
    $a = $os | % {$_.caption}

    ##  Below will list again the server name as well as its OS and SP
    ##  Because the script may not be monitored, this helps confirm the machine has been successfully scanned
        write-host $server “has completed its " $filetype "scan:” “|” “OS:” $a “SP:” “|” $sp


    }

}
#end script

You can do this:

if(in_array($value, range(1, 10)) || in_array($value, range(20, 40))) {
   # enter code here
}

You could simply do this

Camelot seems a fairly powerful solution to extract tables from PDFs in Python.

At first sight it seems to achieve almost as accurate extraction as the tabula-py package suggested by CreekGeek, which is already waaaaay above any other posted solution as of today in terms of reliability, but it is supposedly much more configurable. Furthermore it has its own accuracy indicator (results.parsing_report), and great debugging features.

Both Camelot and Tabula provide the results as Pandas’ DataFrames, so it is easy to adjust tables afterwards.

pip install camelot-py

(Not to be confused with the camelot package.)

import camelot

df_list = []
results = camelot.read_pdf("file.pdf", ...)
for table in results:
    print(table.parsing_report)
    df_list.append(results[0].df)

It can also output results as CSV, JSON, HTML or Excel.

Camelot comes at the expense of a number of dependencies.

NB : Since my input is pretty complex with many different tables I ended up using both Camelot and Tabula, depending on the table, to achieve the best results.

Something that works for me. Enjoy.

In my case, the svn relocate command (as well as svn switch --relocate) failed for some reason (maybe the repo was not moved correctly, or something else). I faced this error:

$ svn relocate NEW_SERVER
svn: E195009: The repository at 'NEW_SERVER' has uuid 'e7500204-160a-403c-b4b6-6bc4f25883ea', but the WC has '3a8c444c-5998-40fb-8cb3-409b74712e46'

I did not want to redownload the whole repository, so I found a workaround. It worked in my case, but generally I can imagine a lot of things can get broken (so either backup your working copy, or be ready to re-checkout the whole repo if something goes wrong).

The repo address and its UUID are saved in the .svn/wc.db SQLite database file in your working copy. Just open the database (e.g. in SQLite Browser), browse table REPOSITORY, and change the root and uuid column values to the new ones. You can find the UUID of the new repo by issuing svn info NEW_SERVER.

Again, treat this as a last resort method.

The magic number comes from UNIX-type systems where the first few bytes of a file held a marker indicating the file type.

Python puts a similar marker into its pyc files when it creates them.

Then the python interpreter makes sure this number is correct when loading it.

Anything that damages this magic number will cause your problem. This includes editing the pyc file or trying to run a pyc from a different version of python (usually later) than your interpreter.

If they are your pyc files, just delete them and let the interpreter re-compile the py files. On UNIX type systems, that could be something as simple as:

rm *.pyc

or:

find . -name '*.pyc' -delete

If they are not yours, you'll have to either get the py files for re-compilation, or an interpreter that can run the pyc files with that particular magic value.

One thing that might be causing the intermittent nature. The pyc that's causing the problem may only be imported under certain conditions. It's highly unlikely it would import sometimes. You should check the actual full stack trace when the import fails?

As an aside, the first word of all my 2.5.1(r251:54863) pyc files is 62131, 2.6.1(r261:67517) is 62161. The list of all magic numbers can be found in Python/import.c, reproduced here for completeness (current as at the time the answer was posted, it may have changed since then):

One form to do this is insert the panel that you want to expand inside a DIV setted as relative: let me show you:

<div style="position:relative">
  <div style="position:absolute; z-index: 1000;">
    your code
  </div>
</div>

You use the first div to position the inner content in a specific area inside your page and the second absolute should be referred to the container (because is relative) The z-index in this case is referred also to container and if it higher that the container should be at top. You can put the style in a CSS class and change the size of the absolute div to expand it on hover or another action that you want to control.

What's wrong with using two regexs (or three)? This makes your intentions more clear and may even improve your performance:

if ($string =~ /^(Clinton|Reagan)/i && $string !~ /Bush/i) { ... }

if (($string =~ /^Clinton/i || $string =~ /^Reagan/i)
        && $string !~ /Bush/i) {
    print "$string\n"
}

You can do this using pure CSS; no JavaScript needed. This utilizes the (somewhat counterintuitive) fact that padding-top percentages are relative to the containing block's width. Here's an example:

  display: inline-block;_x000D_
  position: relative;_x000D_

.wrapper:after {_x000D_

Type: System.String

TrueString if the value of this instance is true, or FalseString if the value of this instance is false.

Remarks

This method returns the constants "True" or "False". Note that XML is case-sensitive, and that the XML specification recognizes "true" and "false" as the valid set of Boolean values. If the String object returned by the ToString() method is to be written to an XML file, its String.ToLower method should be called first to convert it to lowercase.

Here comes the fun fact #1: it doesn't return TrueString or FalseString at all. It uses hardcoded literals "True" and "False". Wouldn't do you any good if it used the fields, because they're marked as readonly, so there's no changing them.

The alternative method, Boolean.ToString(IFormatProvider) is even funnier:

Remarks

The provider parameter is reserved. It does not participate in the execution of this method. This means that the Boolean.ToString(IFormatProvider) method, unlike most methods with a provider parameter, does not reflect culture-specific settings.

What's the solution? Depends on what exactly you're trying to do. Whatever it is, I bet it will require a hack ;)

We recently encountered this error, root cause turned out to be an expired SSL cert on the IIS server. The Load Balancer (infront of our web tier) found the SSL expired, and instead of handling the HTTP traffic over to one of the IIS servers, started showing this error. So basically IIS unable to server requests, for a totally different reason :)

In my case the missing type was referencing an import for java class in a dependent jar. For some reason my project file was missing the javabuilder and therefore couldnt resolve the path to the import.

Why it was missing in the first place I don't know, but adding these lines in fixed the error.

<buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
</buildCommand>

Tested in mysql 5.Dont know about other versions. If you want to keep the row with the lowest id value:

DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id > n2.id AND n1.member_id = n2.member_id and n1.answer_num =n2.answer_num

If you want to keep the row with the highest id value:

DELETE n1 FROM 'yourTableName' n1, 'yourTableName' n2 WHERE n1.id < n2.id AND n1.member_id = n2.member_id and n1.answer_num =n2.answer_num

Sets new value for backgroundPosition on the carousel div when a li in the submenu div is hovered. Removes the backgroundPosition when hovering ends and resets backgroundPosition to old value.

$('#submenu li').hover(function() {
    if ($('#carousel').data('oldbackgroundPosition')==undefined) {
        $('#carousel').data('oldbackgroundPosition', $('#carousel').css('backgroundPosition'));
    }
    $('#carousel').css('backgroundPosition', [enternewvaluehere]);
},
function() {
    var reset = '';
    if ($('#carousel').data('oldbackgroundPosition') != undefined) {
        reset = $('#carousel').data('oldbackgroundPosition');
        $('#carousel').removeData('oldbackgroundPosition');
    }
    $('#carousel').css('backgroundPosition', reset);
});

There is not any safe way to include php file into js.

One thing you can do as define your php file data as javascript global variable in php file. for example i have three variable which i want to use as js.

abc.php

<?php
$abc = "Abc";
$number = 052;
$mydata = array("val1","val2","val3");
?>
<script type="text/javascript">
var abc = '<?php echo $abc?>';
var number = '<?php echo $number ?>';
var mydata = <?php echo json_encode($mydata); ?>;
</script>

After use it directly in your js file wherever you want to use.

abc.js

function test(){
   alert('Print php variable : '+ abc +', '+number); 
}

function printArrVar(){
  alert('print php array variable : '+ JSON.stringify(mydata)); 
}

Beside If you have any critical data which you don't want to show publicly then you can encrypt data with js. and also get original value of it's from js so no one can get it's original value. if they show into publicly.

this is the standard way you can call php script data into js file without including js into php code or php script into js.

Most / all answers caused issues for us when daylight savings time came around. Here's our working solution for all dates, without using JodaTime. It utilizes calendar objects:

public static int daysBetween(Calendar day1, Calendar day2){
    Calendar dayOne = (Calendar) day1.clone(),
            dayTwo = (Calendar) day2.clone();

    if (dayOne.get(Calendar.YEAR) == dayTwo.get(Calendar.YEAR)) {
        return Math.abs(dayOne.get(Calendar.DAY_OF_YEAR) - dayTwo.get(Calendar.DAY_OF_YEAR));
    } else {
        if (dayTwo.get(Calendar.YEAR) > dayOne.get(Calendar.YEAR)) {
            //swap them
            Calendar temp = dayOne;
            dayOne = dayTwo;
            dayTwo = temp;
        }
        int extraDays = 0;

        int dayOneOriginalYearDays = dayOne.get(Calendar.DAY_OF_YEAR);

        while (dayOne.get(Calendar.YEAR) > dayTwo.get(Calendar.YEAR)) {
            dayOne.add(Calendar.YEAR, -1);
            // getActualMaximum() important for leap years
            extraDays += dayOne.getActualMaximum(Calendar.DAY_OF_YEAR);
        }

        return extraDays - dayTwo.get(Calendar.DAY_OF_YEAR) + dayOneOriginalYearDays ;
    }
}

Simply in windows

ctrl + @ (the button 2 in the upper horizontal row of numbers in keyboard)

As pointed out by other answers, in python they return floats probably because of historical reasons to prevent overflow problems. However, they return integers in python 3.

>>> import math
>>> type(math.floor(3.1))
<class 'int'>
>>> type(math.ceil(3.1))
<class 'int'>

You can find more information in PEP 3141.

The second one is fastest. Using strlen will be close if the string is indeed empty, but strlen will always iterate through every character of the string, so if it is not empty, it will do much more work than you need it to.

As James mentioned, the third option wipes the string out before checking, so the check will always succeed but it will be meaningless.

If I understand correctly, what you want to do is divide by the maximum value in each column. You can do this easily using broadcasting.

Starting with your example array:

import numpy as np

x = np.array([[1000,  10,   0.5],
              [ 765,   5,  0.35],
              [ 800,   7,  0.09]])

x_normed = x / x.max(axis=0)

print(x_normed)
# [[ 1.     1.     1.   ]
#  [ 0.765  0.5    0.7  ]
#  [ 0.8    0.7    0.18 ]]

x.max(0) takes the maximum over the 0th dimension (i.e. rows). This gives you a vector of size (ncols,) containing the maximum value in each column. You can then divide x by this vector in order to normalize your values such that the maximum value in each column will be scaled to 1.

If x contains negative values you would need to subtract the minimum first:

x_normed = (x - x.min(0)) / x.ptp(0)

Here, x.ptp(0) returns the "peak-to-peak" (i.e. the range, max - min) along axis 0. This normalization also guarantees that the minimum value in each column will be 0.

step 1. select * from <tablename>;

step 2. just right click on your output(t.e data) then go to last option export it will give u some extension then click on your required extension then apply u will get new file including data.

To make it work I build my directory like this:

Project Public Restrict

So I edited my webconfig for my public folder:

<location path="Project/Public">
    <system.web>
      <authorization>
        <allow users="?"/>
      </authorization>
    </system.web>
  </location>

And for my Restricted folder:

 <location path="Project/Restricted">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorizatio>
    </system.web>
  </location>

See here for the spec of * and ?:

I hope I have helped.

As everyone has pointed out, a team of players is not a list of players. This mistake is made by many people everywhere, perhaps at various levels of expertise. Often the problem is subtle and occasionally very gross, as in this case. Such designs are bad because these violate the Liskov Substitution Principle. The internet has many good articles explaining this concept e.g., http://en.wikipedia.org/wiki/Liskov_substitution_principle

In summary, there are two rules to be preserved in a Parent/Child relationship among classes:

• a Child should require no characteristic less than what completely defines the Parent.
• a Parent should require no characteristic in addition to what completely defines the Child.

In other words, a Parent is a necessary definition of a child, and a child is a sufficient definition of a Parent.

Here is a way to think through ones solution and apply the above principle that should help one avoid such a mistake. One should test ones hypothesis by verifying if all the operations of a parent class are valid for the derived class both structurally and semantically.

• Is a football team a list of football players? ( Do all properties of a list apply to a team in the same meaning)
  • Is a team a collection of homogenous entities? Yes, team is a collection of Players
  • Is the order of inclusion of players descriptive of the state of the team and does the team ensure that the sequence is preserved unless explicitly changed? No, and No
  • Are players expected to be included/dropped based on their sequencial position in the team? No

As you see, only the first characteristic of a list is applicable to a team. Hence a team is not a list. A list would be a implementation detail of how you manage your team, so it should only be used to store the player objects and be manipulated with methods of Team class.

At this point I'd like to remark that a Team class should, in my opinion, not even be implemented using a List; it should be implemented using a Set data structure (HashSet, for example) in most cases.

I wrote about some of the limitations of correlated subqueries in Access/JET SQL a while back, and noted the syntax for joining multiple tables for SQL UPDATEs. Based on that info and some quick testing, I don't believe there's any way to do what you want with Access/JET in a single SQL UPDATE statement. If you could, the statement would read something like this:

UPDATE FUNCTIONS A
INNER JOIN (
  SELECT AA.Func_ID, Min(BB.Tax_Code) AS MinOfTax_Code
  FROM TAX BB, FUNCTIONS AA
  WHERE AA.Func_Pure<=BB.Tax_ToPrice AND AA.Func_Year= BB.Tax_Year
  GROUP BY AA.Func_ID
) B 
ON B.Func_ID = A.Func_ID
SET A.Func_TaxRef = B.MinOfTax_Code

Alternatively, Access/JET will sometimes let you get away with saving a subquery as a separate query and then joining it in the UPDATE statement in a more traditional way. So, for instance, if we saved the SELECT subquery above as a separate query named FUNCTIONS_TAX, then the UPDATE statement would be:

UPDATE FUNCTIONS
INNER JOIN FUNCTIONS_TAX
ON FUNCTIONS.Func_ID = FUNCTIONS_TAX.Func_ID
SET FUNCTIONS.Func_TaxRef = FUNCTIONS_TAX.MinOfTax_Code

However, this still doesn't work.

I believe the only way you will make this work is to move the selection and aggregation of the minimum Tax_Code value out-of-band. You could do this with a VBA function, or more easily using the Access DLookup function. Save the GROUP BY subquery above to a separate query named FUNCTIONS_TAX and rewrite the UPDATE statement as:

UPDATE FUNCTIONS
SET Func_TaxRef = DLookup(
  "MinOfTax_Code", 
  "FUNCTIONS_TAX", 
  "Func_ID = '" & Func_ID & "'"
)

Note that the DLookup function prevents this query from being used outside of Access, for instance via JET OLEDB. Also, the performance of this approach can be pretty terrible depending on how many rows you're targeting, as the subquery is being executed for each FUNCTIONS row (because, of course, it is no longer correlated, which is the whole point in order for it to work).

Good luck!

The 404 page should be set up just before the call to app.listen.Express has support for * in route paths. This is a special character which matches anything. This can be used to create a route handler that matches all requests.

app.get('*', (req, res) => {
  res.render('404', {
    title: '404',
    name: 'test',
    errorMessage: 'Page not found.'
  })
})

This means that you are doing a foreach on something that is not an array.

Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.

Then fix the one where it isn't an array.

How to reproduce this error:

<?php
$skipper = "abcd";
foreach ($skipper as $item){       //the warning happens on this line.
    print "ok";
}
?>

Make sure $skipper is an array.

               /*height*/ 100,
               /*weight*/ 1.0f
                );

In case of Spring Boot and @EnableResourceServer, it is relatively easy and convenient to extend ResourceServerConfigurerAdapter instead of WebSecurityConfigurerAdapter in the Java configuration and register a custom AuthenticationEntryPoint by overriding configure(ResourceServerSecurityConfigurer resources) and using resources.authenticationEntryPoint(customAuthEntryPoint()) inside the method.

Something like this:

@Configuration
@EnableResourceServer
public class CommonSecurityConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.authenticationEntryPoint(customAuthEntryPoint());
    }

    @Bean
    public AuthenticationEntryPoint customAuthEntryPoint(){
        return new AuthFailureHandler();
    }
}

There's also a nice OAuth2AuthenticationEntryPoint that can be extended (since it's not final) and partially re-used while implementing a custom AuthenticationEntryPoint. In particular, it adds "WWW-Authenticate" headers with error-related details.

Hope this will help someone.

Why not use the DialogResult method to close the form?

if(DialogSettingsCancel.ShowDialog() == DialogResult.Yes)
{
     //this will close the form but will keep application open if your 
     //application type is "console" in the properties of the project
     this.Close();
}

For this to work however you will need to do it inside your "WindowSettings" form while you call the DialogSettingsCancel form. Much the same way you would call the OpenFileDialog, or any other Dialog form.

TortoiseGit (Windows)

For anyone using TortoiseGit for Windows, I did this:

(1) Right-click on the folder containing your project. Select TortoiseGit -> Settings.

(2) On the "Git" tab, click the button to "Edit local .git/config".

(3) In the text file that pops up, under the [core] section, add: longpaths = true

Save and close everything, then re-try your commit. For me, this worked.

I hope this minimizes any possible system-wide issues, since we are not editing the global .gitconfig file, but rather just the one for this particular repository.

Just for future reference, this problem happened with me, using Vagrant 1.7.4 and VirtualBox 5.0.10 r104061, when I provisioned a shared folder in / and created a symbolic link to my home folder. Something like this:

/folder
~/folder -> /folder

Apparently, this operation is not allowed by Vagrant due to security purposes and throws the described error.

I solved it by provisioning the desired folder directly to my home directory, such as /home/vagrant/folder.

It’s very simple: Add these lines to server section:

server_tokens off;
more_set_headers 'Server: My Very Own Server';

Without reverting the package name I was using when trying to reinstall, I got this same error. Using the same package name the reinstall was successful.

What does the exclamation mark after the gem name in the 'DEPENDECIES' group mean?

The exclamation mark appears when the gem was installed using a source other than "https://rubygems.org".

SQL Server 2008 databases are version 655. SQL Server 2008 R2 databases are 661. You are trying to attach an 2008 R2 database (v. 661) to an 2008 instance and this is not supported. Once the database has been upgraded to an 2008 R2 version, it cannot be downgraded. You'll have to either upgrade your 2008 SP2 instance to R2, or you have to copy out the data in that database into an 2008 database (eg using the data migration wizard, or something equivalent).

The message is misleading, to say the least, it says 662 because SQL Server 2008 SP2 does support 662 as a database version, this is when 15000 partitions are enabled in the database, see Support for 15000 Partitions.docx. Enabling the support bumps the DB version to 662, disabling it moves it back to 655. But SQL Server 2008 SP2 does not support 661 (the R2 version).

Check that your dependencies were compiled without -f-nortti.

For some projects you have to set it explicitly, like in RocksDB:

USE_RTTI=1 make shared_lib -j4

As doc says also keep in mind the correct value combination:

The setting must be one of the values listed in the following table, or a combination of one "state..." value plus one "adjust..." value. Setting multiple values in either group — multiple "state..." values, for example — has undefined results. Individual values are separated by a vertical bar (|). For example:

<activity android:windowSoftInputMode="stateVisible|adjustResize" . . . >

You need to have your function in the componentDidMount lifecycle since this is the function that is called when the DOM has loaded.

Make use of refs to access the DOM element

<input type="submit" className="nameInput" id="name" value="cp-dev1" onClick={this.writeData} ref = "cpDev1"/>

  componentDidMount: function(){
    var name = React.findDOMNode(this.refs.cpDev1).value;
    this.someOtherFunction(name);
  }

See this answer for more info on How to access the dom element in React

To preselect an option when the form is initialized, the value of the select element must be set to an element attribute of the array you are iterating over and setting the value of option to. Which is the key attribute in this case.

From your example.

<select [id]="question.key" [formControlName]="question.key">
  <option *ngFor="let opt of question.options" [value]="opt.key"</option>
</select>

You are iterating over 'options' to create the select options. So the value of select must be set to the key attribute of an item in options(the one you want to display on initialization). This will display the default of select as the option whose value matches the value you set for select.

You can achieve this by setting the value of the select element in the onInit method like so.

ngOnInit(): void{
    myForm : new FormGroup({
       ...
       question.key : new FormControl(null)
    })
    // Get desired initial value to display on <select>
    desiredValue = question.options.find(opt => opt === initialValue)
    this.myForm.get(question.key).setValue(desiredValue.key)
}

The probelm with your first code block was that you were opening the file as 'r' even though you wanted to write to it using 'w'

with open('/Users/your/path/foo','w') as data:
    data.write(str(dictionary))

If you are working on .NET 4.5 project in VS 2012 (or newer), you can just Special Paste your XML file as classes.

Here are my two cents... Java 8 does contain its own implementation of Base64. However, I found one slightly disturbing difference. To illustrate, I will provide a code example:

My codec wrapper:

public interface MyCodec
{
  static String apacheDecode(String encodedStr)
  {
    return new String(Base64.decodeBase64(encodedStr), Charset.forName("UTF-8"));
  }

  static String apacheEncode(String decodedStr)
  {
    byte[] decodedByteArr = decodedStr.getBytes(Charset.forName("UTF-8"));
    return Base64.encodeBase64String(decodedByteArr);
  }

  static String javaDecode(String encodedStr)
  {
    return new String(java.util.Base64.getDecoder().decode(encodedStr), Charset.forName("UTF-8"));
  }

  static String javaEncode(String decodedStr)
  {
    byte[] decodedByteArr = decodedStr.getBytes(Charset.forName("UTF-8"));
    return java.util.Base64.getEncoder().encodeToString(decodedByteArr);
  }
}

Test Class:

public class CodecDemo
{
  public static void main(String[] args)
  {
    String decodedText = "Hello World!";

    String encodedApacheText = MyCodec.apacheEncode(decodedText);
    String encodedJavaText = MyCodec.javaEncode(decodedText);

    System.out.println("Apache encoded text: " + MyCodec.apacheEncode(encodedApacheText));
    System.out.println("Java encoded text: " + MyCodec.javaEncode(encodedJavaText));

    System.out.println("Encoded results equal: " + encodedApacheText.equals(encodedJavaText));

    System.out.println("Apache decode Java: " + MyCodec.apacheDecode(encodedJavaText));
    System.out.println("Java decode Java: " + MyCodec.javaDecode(encodedJavaText));

    System.out.println("Apache decode Apache: " + MyCodec.apacheDecode(encodedApacheText));
    System.out.println("Java decode Apache: " + MyCodec.javaDecode(encodedApacheText));
  }
}

OUTPUT:

Apache encoded text: U0dWc2JHOGdWMjl5YkdRaA0K

Java encoded text: U0dWc2JHOGdWMjl5YkdRaA==
Encoded results equal: false
Apache decode Java: Hello World!
Java decode Java: Hello World!
Apache decode Apache: Hello World!
Exception in thread "main" java.lang.IllegalArgumentException: Illegal base64 character d
    at java.util.Base64$Decoder.decode0(Base64.java:714)
    at java.util.Base64$Decoder.decode(Base64.java:526)
    at java.util.Base64$Decoder.decode(Base64.java:549)

Notice that the Apache encoded text contain additional line breaks (white spaces) at the end. Therefore, in order for my codec to yield the same result regardless of Base64 implementation, I had to call trim() on the Apache encoded text. In my case, I simply added the aforementioned method call to the my codec's apacheDecode() as follows:

return Base64.encodeBase64String(decodedByteArr).trim();

Once this change was made, the results are what I expected to begin with:

Apache encoded text: U0dWc2JHOGdWMjl5YkdRaA==
Java encoded text: U0dWc2JHOGdWMjl5YkdRaA==
Encoded results equal: true
Apache decode Java: Hello World!
Java decode Java: Hello World!
Apache decode Apache: Hello World!
Java decode Apache: Hello World!

CONCLUSION: If you want to switch from Apache Base64 to Java, you must:

1. Decode encoded text with your Apache decoder.
2. Encode resulting (plain) text with Java.

If you switch without following these steps, most likely you will run into problems. That is how I made this discovery.

in swift it quite simple

Write this code in ViewDidLoad() function

let tap = UITapGestureRecognizer(target: self, action: #selector(tapHandler(gesture:)))
    tap.numberOfTapsRequired = 2
    tapView.addGestureRecognizer(tap)

The Handler Part this could be in viewDidLoad or outside the viewDidLoad, batter is put in extension

@objc func tapHandler(gesture: UITapGestureRecognizer) {
    currentGestureStates.text = "Double Tap"
} 

here i'm just testing the code by printing the output if you want to make an action you can do whatever you want or more practise and read

Honestly though, whether there is a way for it to evaluate to true or not (and as others have shown, there are multiple ways), the answer I'd be looking for, speaking as someone who has conducted hundreds of interviews, would be something along the lines of:

"Well, maybe yes under some weird set of circumstances that aren't immediately obvious to me... but if I encountered this in real code then I would use common debugging techniques to figure out how and why it was doing what it was doing and then immediately refactor the code to avoid that situation... but more importantly: I would absolutely NEVER write that code in the first place because that is the very definition of convoluted code, and I strive to never write convoluted code".

I guess some interviewers would take offense to having what is obviously meant to be a very tricky question called out, but I don't mind developers who have an opinion, especially when they can back it up with reasoned thought and can dovetail my question into a meaningful statement about themselves.

With this method you can set font size, font style and Header background also. there are have 2 method for this

First Method

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section{
        UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
        header.backgroundView.backgroundColor = [UIColor darkGrayColor];
        header.textLabel.font=[UIFont fontWithName:@"Open Sans-Regular" size:12];
        [header.textLabel setTextColor:[UIColor whiteColor]];
    }

Second Method

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
    UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 30)];
//    myLabel.frame = CGRectMake(20, 8, 320, 20);
    myLabel.font = [UIFont fontWithName:@"Open Sans-Regular" size:12];
    myLabel.text = [NSString stringWithFormat:@"   %@",[self tableView:FilterSearchTable titleForHeaderInSection:section]];

    myLabel.backgroundColor=[UIColor blueColor];
    myLabel.textColor=[UIColor whiteColor];
    UIView *headerView = [[UIView alloc] init];
    [headerView addSubview:myLabel];
    return headerView;
}

BASED ON LARAVEL 5.7 & ABOVE

To get all segments of current URL:

$current_uri = request()->segments();

To get segment posts from http://example.com/users/posts/latest/

NOTE: Segments are an array that starts at index 0. The first element of array starts after the TLD part of the url. So in the above url, segment(0) will be users and segment(1) will be posts.

//get segment 0
$segment_users = request()->segment(0); //returns 'users'
//get segment 1
$segment_posts = request()->segment(1); //returns 'posts'

You may have noted that the segment method only works with the current URL ( url()->current() ). So I designed a method to work with previous URL too by cloning the segment() method:

public function index()
{
    $prev_uri_segments = $this->prev_segments(url()->previous());
}

 /**
 * Get all of the segments for the previous uri.
 *
 * @return array
 */
public function prev_segments($uri)
{
    $segments = explode('/', str_replace(''.url('').'', '', $uri));

    return array_values(array_filter($segments, function ($value) {
        return $value !== '';
    }));
}

I found String.localizedStringWithFormat to work quite well:

Example:

let value: Float = 0.33333
let unit: String = "mph"

yourUILabel.text = String.localizedStringWithFormat("%.2f %@", value, unit)

It can help you to convert any input data to user desired enum. Suppose you have an enum like below which by default int. Please add a Default value at first of your enum. Which is used at helpers medthod when there is no match found with input value.

public enum FriendType  
{
    Default,
    Audio,
    Video,
    Image
}

public static class EnumHelper<T>
{
    public static T ConvertToEnum(dynamic value)
    {
        var result = default(T);
        var tempType = 0;

        //see Note below
        if (value != null &&
            int.TryParse(value.ToString(), out  tempType) && 
            Enum.IsDefined(typeof(T), tempType))
        {
            result = (T)Enum.ToObject(typeof(T), tempType); 
        }
        return result;
    }
}

N.B: Here I try to parse value into int, because enum is by default int If you define enum like this which is byte type.

public enum MediaType : byte
{
    Default,
    Audio,
    Video,
    Image
} 

You need to change parsing at helper method from

int.TryParse(value.ToString(), out  tempType)

to

byte.TryParse(value.ToString(), out tempType)

I check my method for following inputs

EnumHelper<FriendType>.ConvertToEnum(null);
EnumHelper<FriendType>.ConvertToEnum("");
EnumHelper<FriendType>.ConvertToEnum("-1");
EnumHelper<FriendType>.ConvertToEnum("6");
EnumHelper<FriendType>.ConvertToEnum("");
EnumHelper<FriendType>.ConvertToEnum("2");
EnumHelper<FriendType>.ConvertToEnum(-1);
EnumHelper<FriendType>.ConvertToEnum(0);
EnumHelper<FriendType>.ConvertToEnum(1);
EnumHelper<FriendType>.ConvertToEnum(9);

sorry for my english

I think this could help - CASE the columns value to NULL if it's duplicate - then it's not appended to LISTAGG string:

with test_data as 
(
      select 1 as col1, 2 as col2, 'Smith' as created_by from dual
union select 1, 2, 'John' from dual
union select 1, 3, 'Ajay' from dual
union select 1, 4, 'Ram' from dual
union select 1, 5, 'Jack' from dual
union select 2, 5, 'Smith' from dual
union select 2, 6, 'John' from dual
union select 2, 6, 'Ajay' from dual
union select 2, 6, 'Ram' from dual
union select 2, 7, 'Jack' from dual
)
SELECT col1  ,
      listagg(col2 , ',') within group (order by col2 ASC) AS orig_value,
      listagg(CASE WHEN rwn=1 THEN col2 END , ',') within group (order by col2 ASC) AS distinct_value
from 
    (
    select row_number() over (partition by col1,col2 order by 1) as rwn, 
           a.*
    from test_data a
    ) a
GROUP BY col1   

Results in:

COL1  ORIG         DISTINCT
1   2,2,3,4,5   2,3,4,5
2   5,6,6,6,7   5,6,7

if (Data_Array["XML_File"] != "") String xmlfile = Data_Array["XML_File"];

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

You could make a helper method. Something like:

public bool IsNumeric(string input) {
    int test;
    return int.TryParse(input, out test);
}

Even though an answer has already been accepted, I would like to present what might even be the simplest option:

$ mysqladmin -u bob -p -i 1 processlist

This will print the current queries on your screen every second.

• -u The mysql user you want to execute the command as
• -p Prompt for your password (so you don't have to save it in a file or have the command appear in your command history)
• i The interval in seconds.
• Use the --verbose flag to show the full process list, displaying the entire query for each process. (Thanks, nmat)

There is a possible downside: fast queries might not show up if they run between the interval that you set up. IE: My interval is set at one second and if there is a query that takes .02 seconds to run and is ran between intervals, you won't see it.

Use this option preferably when you quickly want to check on running queries without having to set up a listener or anything else.

white spaces matter. when block is finished, that's when the function definition is finished.

when function runs, it keeps going until it finishes, or until return or yield statement is encountered. If function finishes without encountering return or yield statements None is returned implicitly.

there is plenty more information in the tutorial.

I believe the simplest solution would be to use find. I do not like to have multiple .gitignore hanging around in sub-directories and I prefer to manage a unique, top-level .gitignore. To do so you could simply append the found files to your .gitignore. Supposing that /public/static/ is your project/git home I would use something like:

find . -type f -name *.js | cut -c 3- >> .gitignore

I found that cutting out the ./ at the beginning is often necessary for git to understand which files to avoid. Therefore the cut -c 3-.

I had the same problem, two list boxes and two buttons.

The data in the list boxes was being loaded from a database and you could move items between boxes by clicking the buttons.

I was getting an invalid postback.

turns out that it was the data had carriage return line feeds in it which you cannot see when displayed in the list box.

worked fine in every browser except IE 10 and IE 11.

Remove the carriage return line feeds and all works fine.

try to run the code below

- (void)viewDidLoad {
    [super viewDidLoad];
    UIWindow *w = [[UIApplication sharedApplication] keyWindow];
    UIView *v = [w.subviews objectAtIndex:0];

    NSLog(@"%@", NSStringFromCGRect(v.frame));
    NSLog(@"%@", NSStringFromCGRect(v.bounds));
}

the output of this code is:

case device orientation is Portrait

{{0, 0}, {768, 1024}}
{{0, 0}, {768, 1024}}

case device orientation is Landscape

{{0, 0}, {768, 1024}}
{{0, 0}, {1024, 768}}

obviously, you can see the difference between frame and bounds

Using Windows Command Prompt:

rmdir /s /q folder

Using Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

You just need a loop that iterates the number of times given by n and prints a space each time. This would do:

while (n--) {
  std::cout << ' ';
}

Here's a slightly more functional version of the answer m93a provided.

const toFixedNumber = (toFixTo = 2, base = 10) => num => {
  const pow = Math.pow(base, toFixTo)
  return +(Math.round(num * pow) / pow)
}

const oneNumber = 10.12323223

const result1 = toFixedNumber(2)(oneNumber) // 10.12
const result2 = toFixedNumber(3)(oneNumber) // 10.123

// or using pipeline-operator
const result3 = oneNumber |> toFixedNumber(2) // 10.12

Firstly there is an extra } after every array object.

Secondly "geodata" is a JSONArray. So instead of JSONObject geoObject = jObject.getJSONObject("geodata"); you have to get it as JSONArray geoObject = jObject.getJSONArray("geodata");

Once you have the JSONArray you can fetch each entry in the JSONArray using geoObject.get(<index>).

I am using org.codehaus.jettison.json.

You can also define a variable without the EnvInject Plugin within your Groovy System Script:

import hudson.model.*
def build = Thread.currentThread().executable
def pa = new ParametersAction([
  new StringParameterValue("FOO", "BAR")
])
build.addAction(pa)

Then you can access this variable in the next build step which (for example) is an windows batch command:

@echo off
Setlocal EnableDelayedExpansion
echo FOO=!FOO!

This echo will show you "FOO=BAR".

Regards

just sudo pip install packagename

First:

chmod 777 ./MigrateNshell.sh

Then:

./MigrateNshell.sh

Or, add your program to a directory recognized in your $PATH variable. Example: Path Variable Example Which will then allow you to call your program without ./

you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.

You can truncate all information after the month using date_trunc(text, timestamp):

select date_trunc('month',created_at)::date as date 
from orders 
order by date DESC;

created_at = '2019-12-16 18:28:13'

Output 1:

date_trunc('day',created_at)
// 2019-12-16 00:00:00

Output 2:

date_trunc('day',created_at)::date 
// 2019-12-16

Output 3:

date_trunc('month',created_at)::date 
// 2019-12-01

Output 4:

date_trunc('year',created_at)::date 
// 2019-01-01

The memset function is designed to be flexible and simple, even at the expense of speed. In many implementations, it is a simple while loop that copies the specified value one byte at a time over the given number of bytes. If you are wanting a faster memset (or memcpy, memmove, etc), it is almost always possible to code one up yourself.

The simplest customization would be to do single-byte "set" operations until the destination address is 32- or 64-bit aligned (whatever matches your chip's architecture) and then start copying a full CPU register at a time. You may have to do a couple of single-byte "set" operations at the end if your range doesn't end on an aligned address.

Depending on your particular CPU, you might also have some streaming SIMD instructions that can help you out. These will typically work better on aligned addresses, so the above technique for using aligned addresses can be useful here as well.

For zeroing out large sections of memory, you may also see a speed boost by splitting the range into sections and processing each section in parallel (where number of sections is the same as your number or cores/hardware threads).

Most importantly, there's no way to tell if any of this will help unless you try it. At a minimum, take a look at what your compiler emits for each case. See what other compilers emit for their standard 'memset' as well (their implementation might be more efficient than your compiler's).
