Update your connection string as shown below (without port variable as well):

MysqlConn.ConnectionString = "Server=127.0.0.1;Database=patholabs;Uid=pankaj;Pwd=master;"

Hope this helps...

What is the target platform of your application? I think you should set the platform to x86, do not set it to Any CPU.

If the problem is 100% here

EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);

There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.

EDIT after several hours

There were some problems:

• MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.

• several event handlers weren't wired up to control events

Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.

I had the same issue - a .dll working all the time, then my computer crashed and afterwards I had this problem of 'could not load file or assembly ....dll'

Two possible solutions: when the computer crashed there may be some inconsistent files in

C:\Users\<yourUserName>\AppData\Local\Temp\Temporary ASP.NET Files

Deleting that folder, recompiling and the error was gone.

Once I had also to delete my packages folder (I had read that somewhere else). Allow Visual Studio / nuget to install missing packages (or manually reinstall) and afterwards everything was fine again.

I got this error when trying to log to an NLog target that no longer existed.

Microsoft also released a hotfix (July 2nd, 2007) to prevent the error "Attempted to read or write protected memory" that has been plaguing the .NET 2.0 platform for some time now. Look at http://support.microsoft.com/kb/923028 - not sure if it applies to you, but thought you might like to check it out.

Definitely too many handles(memory leak issue):

IT Jungles: System.ComponentModel.Win32Exception: Error creating window handle

Also, in .NET 4 this is even easier if you use the dynamic keyword:

dynamic document = this.browser.Document;
dynamic head = document.GetElementsByTagName("head")[0];
dynamic scriptEl = document.CreateElement("script");
scriptEl.text = ...;
head.AppendChild(scriptEl);

I had the same problem and solved it using a boolean flag that gets set when the form is closing (the System.Timers.Timer does not have an IsDisposed property). Everywhere on the form I was starting the timer, I had it check this flag. If it was set, then don't start the timer. Here's the reason:

The Reason:

I was stopping and disposing of the timer in the form closing event. I was starting the timer in the Timer_Elapsed() event. If I were to close the form in the middle of the Timer_Elapsed() event, the timer would immediately get disposed by the Form_Closing() event. This would happen before the Timer_Elapsed() event would finish and more importantly, before it got to this line of code:

_timer.Start()

As soon as that line was executed an ObjectDisposedException() would get thrown with the error you mentioned.

The Solution:

Private Sub myForm_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
    ' set the form closing flag so the timer doesn't fire even after the form is closed.
    _formIsClosing = True
    _timer.Stop()
    _timer.Dispose()
End Sub

Here's the timer elapsed event:

Private Sub Timer_Elapsed(ByVal sender As System.Object, ByVal e As System.Timers.ElapsedEventArgs) Handles _timer.Elapsed
    ' Don't want the timer stepping on itself (ie. the time interval elapses before the first call is done processing)
    _timer.Stop()

    ' do work here

    ' Only start the timer if the form is open. Without this check, the timer will run even if the form is closed.
    If Not _formIsClosing Then
        _timer.Interval = _refreshInterval
        _timer.Start() ' ObjectDisposedException() is thrown here unless you check the _formIsClosing flag.
    End If
End Sub

The interesting thing to know, even though it would throw the ObjectDisposedException when attempting to start the timer, the timer would still get started causing it to run even when the form was closed (the thread would only stop when the application was closed).

The requests.Session() solution assisted with logging into a form with CSRF Protection (as used in Flask-WTF forms). Check if a csrf_token is required as a hidden field and add it to the payload with the username and password:

import requests
from bs4 import BeautifulSoup

payload = {
    'email': '[email protected]',
    'password': 'passw0rd'
}     

with requests.Session() as sess:
    res = sess.get(server_name + '/signin')
    signin = BeautifulSoup(res._content, 'html.parser')
    payload['csrf_token'] = signin.find('input', id='csrf_token')['value']
    res = sess.post(server_name + '/auth/login', data=payload)

In Python 2 use the tkFileDialog module.

import tkFileDialog

tkFileDialog.askopenfilename()

In Python 3 use the tkinter.filedialog module.

import tkinter.filedialog

tkinter.filedialog.askopenfilename()

You can do this by providing in class numbers:

• A method that returns the ArrayList object itself.
• A method that returns a non-modifiable wrapper of the ArrayList. This prevents modification to the list without the knowledge of the class numbers.
• Methods that provide the set of operations you want to support from class numbers. This allows class numbers to control the set of operations supported.

By the way, there is a strong convention that Java class names are uppercased.

Case 1 (simple getter):

public class Numbers {
      private List<Integer> list;
      public List<Integer> getList() { return list; }
      ...
}

Case 2 (non-modifiable wrapper):

public class Numbers {
      private List<Integer> list;
      public List<Integer> getList() { return Collections.unmodifiableList( list ); }
      ...
}

Case 3 (specific methods):

public class Numbers {
      private List<Integer> list;
      public void addToList( int i ) { list.add(i); }
      public int getValueAtIndex( int index ) { return list.get( index ); }
      ...
}

From git reset

"pull" or "merge" always leaves the original tip of the current branch in ORIG_HEAD.

git reset --hard ORIG_HEAD

Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.

git reset --merge ORIG_HEAD

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "git reset --hard ORIG_HEAD" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge" keeps your local changes.

Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).

In addition, merge always sets '.git/ORIG_HEAD' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD'.

Note: from here

HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.

So HEAD is NOT a synonym for "current branch" everywhere already.

HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).

But it almost always means the "current commit".
It is the commit "git commit" builds on top of, and "git diff --cached" and "git status" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).

Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".

HEAD@{5.minutes.ago} could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".

git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

See commit cdfd948

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.

function xml2array ( $xmlObject, $out = array () )
{
    foreach ( (array) $xmlObject as $index => $node )
        $out[$index] = ( is_object ( $node ) ) ? xml2array ( $node ) : $node;

    return $out;
}

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

You could try something like this if you want to use cut:

echo "1:2:3:4:5" | cut -d ":" -f5

You can also use grep try like this :

echo " 1:2:3:4:5" | grep -o '[^:]*$'

You have two options:

Either use:

sb.setLength(0);  // It will just discard the previous data, which will be garbage collected later.  

Or use:

sb.delete(0, sb.length());  // A bit slower as it is used to delete sub sequence.  

NOTE

Avoid declaring StringBuffer or StringBuilder objects within the loop else it will create new objects with each iteration. Creating of objects requires system resources, space and also takes time. So for long run, avoid declaring them within a loop if possible.

Step 1 - Getting the URL Right

Many of the answers here were valid until recently. For now, the ONLY supported param is url, and the new share link is as follows...

https://www.linkedin.com/sharing/share-offsite/?url={url}

Make sure url is encoded, using something like fixedEncodeURIComponent().

Source: Official Microsoft.com Linkedin Share Plugin Documentation. All LinkedIn.com links for developer documentation appear to be blank pages now -- perhaps related to the acquisition of LinkedIn by Microsoft.

Step 2 - Setting Custom Parameters (Title, Image, Summary, etc.)

Once upon a time, you could use these params: title, summary, source. But if you look closely at all of the documentation, there is actually still a way to still set summary, title, etc.! Put these in the <head> block of the page you want to share...

• <meta property='og:title' content='Title of the article"/>
• <meta property='og:image' content='//media.example.com/ 1234567.jpg"/>
• <meta property='og:description' content='Description that will show in the preview"/>
• <meta property='og:url' content='//www.example.com/URL of the article" />

Then LinkedIn will use these! Source: LinkedIn Developer Docs: Making Your Website Shareable on LinkedIn.

Step 3 - Verifying LinkedIn Share Results

Not sure you did everything right? Take the URL of the page you are sharing (i.e., example.com, not linkedin.com/share?url=example.com), and input that URL into the following: LinkedIn Post Inspector. This will tell you everything about how your URL is being shared!

This also pulls/invalidates the current cache of your page, and then refreshes it (in case you have a stuck, cached version of your page in LinkedIn's database). Because it pulls the cache, then refreshes it, sometimes it's best to use the LinkedIn Post Inspector twice, and use the second result as the expected output.

Still not sure? Here's an online demo I built with 20+ social share services. Inspect the source code and find out for yourself how exactly the LinkedIn sharing is working.

Want More Social Sharing Services?

I have been maintaining a Github Repo that's been tracking social-share URL formats since 2012, check it out: Github: Social Share URLs.

Why not join in on all the social share url's?

Since you want to check whether textboxes contains any value or not your code should do the job. You should be more specific about the error you are having. You can also do:

if(textBox1.Text == string.Empty || textBox2.Text == string.Empty)
   {
    MessageBox.Show("You must enter a value into both boxes");
   }

EDIT 2: based on @JonSkeet comments:

Usage of string.Compare is not required as per OP's original unedited post. String.Equals should do the job if one wants to compare strings, and StringComparison may be used to ignore case for the comparison. string.Compare should be used for order comparison. Originally the question contain this comparison,

string testString = "This is a test";
string testString2 = "This is not a test";

if (testString == testString2)
{
    //do some stuff;
}

the if statement can be replaced with

if(testString.Equals(testString2))

or following to ignore case.

if(testString.Equals(testString2,StringComparison.InvariantCultureIgnoreCase)) 

In SQL you can not have a variable array.
However, the best alternative solution is to use a temporary table.

It's the Substring method of String, with the first argument set to 0.

 myString.Substring(0,1);

drand48(3) is the POSIX standard way. GLibC also provides a reentrant version, drand48_r(3).

The function was declared obsolete in SVID 3 but no adequate alternative was provided so IEEE Std 1003.1-2013 still includes it and has no notes that it's going anywhere anytime soon.

In Windows, the standard way is CryptGenRandom().

Also, you can create your own outerHeight for HTML elements. I don't know if it works in IE, but it works in Chrome. Perhaps, you can enhance the code below using currentStyle, suggested in the answer above.

Object.defineProperty(Element.prototype, 'outerHeight', {
    'get': function(){
        var height = this.clientHeight;
        var computedStyle = window.getComputedStyle(this); 
        height += parseInt(computedStyle.marginTop, 10);
        height += parseInt(computedStyle.marginBottom, 10);
        height += parseInt(computedStyle.borderTopWidth, 10);
        height += parseInt(computedStyle.borderBottomWidth, 10);
        return height;
    }
});

This piece of code allow you to do something like this:

document.getElementById('foo').outerHeight

According to caniuse.com, getComputedStyle is supported by main browsers (IE, Chrome, Firefox).

I remember it this way:

1. IEnumerable has one method GetEnumerator() which allows one to read through the values in a collection but not write to it. Most of the complexity of using the enumerator is taken care of for us by the for each statement in C#. IEnumerable has one property: Current, which returns the current element.

2. ICollection implements IEnumerable and adds few additional properties the most use of which is Count. The generic version of ICollection implements the Add() and Remove() methods.

3. IList implements both IEnumerable and ICollection, and add the integer indexing access to items (which is not usually required, as ordering is done in database).

d = <dict>
values = d.values()

You can access your array keys like so:

foreach ($array as $key => $value)

Not sure whether it would help you or not but it works to me:

l = ["a", "b", "c", "d", "e"]
outRes = dict((l[i], l[i+1]) if i+1 < len(l) else (l[i], '') for i in xrange(len(l)))

Using deferreds like Futures.

var sequence = Futures.sequence();

sequence
  .then(function(next) {
     http.get({}, next);
  })
  .then(function(next, res) {
     res.on("data", next);
  })
  .then(function(next, d) {
     http.get({}, next);
  })
  .then(function(next, res) {
    ...
  })

If you need to pass scope along then just do something like this

  .then(function(next, d) {
    http.get({}, function(res) {
      next(res, d);
    });
  })
  .then(function(next, res, d) { })
    ...
  })

If you give each of these instances a class you can use

$('.yourClass').upload()

.Net provides the TimeSpan class to do the math for you.

var time1 = new Date(YYYY, MM, DD, 0, 0, 0, 0)
var time2 = new Date(ZZZZ, NN, EE, 0, 0, 0, 0)

Dim ts As TimeSpan = time2.Subtract(time1)

ts.TotalSeconds

Another option is to right click on your jar file which would be under (Your Project)->Referenced Libraries->(your jar) and click on properties. Then click on Java Source Attachment. And then in location path put in the location for your source jar file.

This is just another approach to attaching your source file.

My R use 1970-01-01:

>as.Date(15103, origin="1970-01-01")
[1] "2011-05-09"

and this matches the calculation from

>as.numeric(as.Date(15103, origin="1970-01-01"))

It is best to use two DateTimePickers for the Job One will be the default for the date section and the second DateTimePicker is for the time portion. Format the second DateTimePicker as follows.

      timePortionDateTimePicker.Format = DateTimePickerFormat.Time;
      timePortionDateTimePicker.ShowUpDown = true;

The Two should look like this after you capture them

To get the DateTime from both these controls use the following code

DateTime myDate = datePortionDateTimePicker.Value.Date + 
                    timePortionDateTimePicker.Value.TimeOfDay; 

To assign the DateTime to both these controls use the following code

datePortionDateTimePicker.Value  = myDate.Date;  
timePortionDateTimePicker.Value  = myDate.TimeOfDay; 

You can Use both disabled or readonly attribute of input . Using disable attribute will omit that value at form submit, so if you want that values at submit event make them readonly instead of disable.

<input type="text" readonly> 

or

 <input type="text" disabled>

By code:

btn_edit.IsEnabled = true;

By XAML:

<Button Content="Edit data" Grid.Column="1" Name="btn_edit" Grid.Row="1" IsEnabled="False" />

Found a really helpful link for that. Using SQLCMD for this is really easier than solving this with a stored procedure

How do you plan to save last saved position with RecyclerView.State?

You can always rely on ol' good save state. Extend RecyclerView and override onSaveInstanceState() and onRestoreInstanceState():

    @Override
    protected Parcelable onSaveInstanceState() {
        Parcelable superState = super.onSaveInstanceState();
        LayoutManager layoutManager = getLayoutManager();
        if(layoutManager != null && layoutManager instanceof LinearLayoutManager){
            mScrollPosition = ((LinearLayoutManager) layoutManager).findFirstVisibleItemPosition();
        }
        SavedState newState = new SavedState(superState);
        newState.mScrollPosition = mScrollPosition;
        return newState;
    }

    @Override
    protected void onRestoreInstanceState(Parcelable state) {
        super.onRestoreInstanceState(state);
        if(state != null && state instanceof SavedState){
            mScrollPosition = ((SavedState) state).mScrollPosition;
            LayoutManager layoutManager = getLayoutManager();
            if(layoutManager != null){
              int count = layoutManager.getItemCount();
              if(mScrollPosition != RecyclerView.NO_POSITION && mScrollPosition < count){
                  layoutManager.scrollToPosition(mScrollPosition);
              }
            }
        }
    }

    static class SavedState extends android.view.View.BaseSavedState {
        public int mScrollPosition;
        SavedState(Parcel in) {
            super(in);
            mScrollPosition = in.readInt();
        }
        SavedState(Parcelable superState) {
            super(superState);
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            super.writeToParcel(dest, flags);
            dest.writeInt(mScrollPosition);
        }
        public static final Parcelable.Creator<SavedState> CREATOR
                = new Parcelable.Creator<SavedState>() {
            @Override
            public SavedState createFromParcel(Parcel in) {
                return new SavedState(in);
            }

            @Override
            public SavedState[] newArray(int size) {
                return new SavedState[size];
            }
        };
    }

Query objects in Mongo by default AND expressions together. Mongo currently does not include an OR operator for such queries, however there are ways to express such queries.

Use "in" or "where".

Its gonna be something like this:

db.mycollection.find( { $where : function() { 
return ( this.startTime < Now() && this.expireTime > Now() || this.expireTime == null ); } } );

Ok. I found a program buried deep in other files from the beginning of the year that does what I want. I can't really comment on the suggestions offered because I'm not an experienced spim or low level programmer.Here it is:

         .text
         .globl __start
    __start:
         la $a0,str1 #Load and print string asking for string
         li $v0,4
         syscall

         li $v0,8 #take in input
         la $a0, buffer #load byte space into address
         li $a1, 20 # allot the byte space for string
         move $t0,$a0 #save string to t0
         syscall

         la $a0,str2 #load and print "you wrote" string
         li $v0,4
         syscall

         la $a0, buffer #reload byte space to primary address
         move $a0,$t0 # primary address = t0 address (load pointer)
         li $v0,4 # print string
         syscall

         li $v0,10 #end program
         syscall


               .data
             buffer: .space 20
             str1:  .asciiz "Enter string(max 20 chars): "
             str2:  .asciiz "You wrote:\n"
             ###############################
             #Output:
             #Enter string(max 20 chars): qwerty 123
             #You wrote:
             #qwerty 123
             #Enter string(max 20 chars):   new world oreddeYou wrote:
             #  new world oredde //lol special character
             ###############################

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

In modern browsers, you can accomplish this with string.matchAll().

The benefit to this approach vs RegExp.exec() is that it does not rely on the regex being stateful, as in @Gumbo's answer.

let regexp = /bar/g;
let str = 'foobarfoobar';

let matches = [...str.matchAll(regexp)];
matches.forEach((match) => {
    console.log("match found at " + match.index);
});

If you have access to numpy,

a_transposed = a.T
# Get first row
print(a_transposed[0])

The benefit of this method is that if you want the "second" element in a 2d list, all you have to do now is a_transposed[1]. The a_transposed object is already computed, so you do not need to recalculate.

Description

Finding the first element in a 2-D list can be rephrased as find the first column in the 2d list. Because your data structure is a list of rows, an easy way of sampling the value at the first index in every row is just by transposing the matrix and sampling the first list.

>= PHP 7.3

setcookie('key', 'value', ['samesite' => 'None', 'secure' => true]);

< PHP 7.3

exploit the path
setcookie('key', 'value', time()+(7*24*3600), "/; SameSite=None; Secure");

Emitting javascript

echo "<script>document.cookie('key=value; SameSite=None; Secure');</script>";

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

In addition to the answer of @Charles-Duffy, you can use winpty directly without installing/downloading anything extra. Just run winpty c:/Python27/python.exe. The utility winpty.exe can be found at Git\usr\bin. I'm using Git for Windows v2.7.1

The prebuilt binaries from @Charles-Duffy is version 0.1.1(according to the file name), while the included one is 0.2.2

Once you clear the interval using clearInterval you could setInterval once again. And to avoid repeating the callback externalize it as a separate function:

var ticker = function() {
    console.log('idle');
};

then:

var myTimer = window.setInterval(ticker, 4000);

then when you decide to restart:

window.clearInterval(myTimer);
myTimer = window.setInterval(ticker, 4000);

After searching stackoverflow and the web a lot, I've got to conclution that the best way of doing it is like this:

- (BOOL)isEndDateIsSmallerThanCurrent:(NSDate *)checkEndDate
{
    NSDate* enddate = checkEndDate;
    NSDate* currentdate = [NSDate date];
    NSTimeInterval distanceBetweenDates = [enddate timeIntervalSinceDate:currentdate];
    double secondsInMinute = 60;
    NSInteger secondsBetweenDates = distanceBetweenDates / secondsInMinute;

    if (secondsBetweenDates == 0)
        return YES;
    else if (secondsBetweenDates < 0)
        return YES;
    else
        return NO;
}

You can change it to difference between hours also.

Enjoy!

Edit 1

If you want to compare date with format of dd/MM/yyyy only, you need to add below lines between NSDate* currentdate = [NSDate date]; && NSTimeInterval distance

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]
                          autorelease]];

NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];

currentdate = [dateFormatter dateFromString:stringDate];

try

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    [CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [smalldatetime] NOT NULL

)

PS I think a smalldatetime is good enough. You may decide differently.

Can you not do this at the "moment of impact" ?

In Sql Server, this is common:

Update dbo.MyTable 
Set 

ColA = @SomeValue , 
UpdateDS = CURRENT_TIMESTAMP
Where...........

Sql Server has a "timestamp" datatype.

But it may not be what you think.

Here is a reference:

http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx

Here is a little RowVersion (synonym for timestamp) example:

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)


INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Maybe a complete working example:

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS

BEGIN

Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where 
triggerInsertedTable.Name = myAlias.Name

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Matching on the "Name" value is probably not wise.

Try this more mainstream example with a SurrogateKey

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    SurrogateKey int not null Primary Key Identity (1001,1),
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS

BEGIN

   UPDATE dbo.Names
    SET UpdateTS = CURRENT_TIMESTAMP
    From  dbo.Names myAlias
    WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

I found this post as I was having the same issue, this was the solution that worked for me. As opposed to replacing the input's value just remove it and absolutely position a span behind it that is the same size, the span can have a :before pseudo class applied to it with the icon font of your choice.

<style type="text/css">

form {position: relative; }
.mystyle:before {content:url(smiley.gif); width: 30px; height: 30px; position: absolute; }
.mystyle {color:red; width: 30px; height: 30px; z-index: 1; position: absolute; }
</style>

<form>
<input class="mystyle" type="text" value=""><span class="mystyle"></span>
</form>

For a laugh, thought I'd try and get a single LINQ statement by using the new C# 6 null-conditional operator. Looks pretty crazy and probably horribly inefficient, but it works.

private string GetLocalIPv4(NetworkInterfaceType type = NetworkInterfaceType.Ethernet)
{
    // Bastardized from: http://stackoverflow.com/a/28621250/2685650.

    return NetworkInterface
        .GetAllNetworkInterfaces()
        .FirstOrDefault(ni =>
            ni.NetworkInterfaceType == type
            && ni.OperationalStatus == OperationalStatus.Up
            && ni.GetIPProperties().GatewayAddresses.FirstOrDefault() != null
            && ni.GetIPProperties().UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork) != null
        )
        ?.GetIPProperties()
        .UnicastAddresses
        .FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork)
        ?.Address
        ?.ToString()

There isn't currently a built-in PowerShell method for doing the SFTP part. You'll have to use something like psftp.exe or a PowerShell module like Posh-SSH.

Here is an example using Posh-SSH:

# Set the credentials
$Password = ConvertTo-SecureString 'Password1' -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ('root', $Password)

# Set local file path, SFTP path, and the backup location path which I assume is an SMB path
$FilePath = "C:\FileDump\test.txt"
$SftpPath = '/Outbox'
$SmbPath = '\\filer01\Backup'

# Set the IP of the SFTP server
$SftpIp = '10.209.26.105'

# Load the Posh-SSH module
Import-Module C:\Temp\Posh-SSH

# Establish the SFTP connection
$ThisSession = New-SFTPSession -ComputerName $SftpIp -Credential $Credential

# Upload the file to the SFTP path
Set-SFTPFile -SessionId ($ThisSession).SessionId -LocalFile $FilePath -RemotePath $SftpPath

#Disconnect all SFTP Sessions
Get-SFTPSession | % { Remove-SFTPSession -SessionId ($_.SessionId) }

# Copy the file to the SMB location
Copy-Item -Path $FilePath -Destination $SmbPath

Some additional notes:

• You'll have to download the Posh-SSH module which you can install to your user module directory (e.g. C:\Users\jon_dechiro\Documents\WindowsPowerShell\Modules) and just load using the name or put it anywhere and load it like I have in the code above.
• If having the credentials in the script is not acceptable you'll have to use a credential file. If you need help with that I can update with some details or point you to some links.
• Change the paths, IPs, etc. as needed.

That should give you a decent starting point.

So, I'm used to use

var nameOfList = new List("objectName", "objectName", "objectName")

This is how it works for me but might be different for you, I recommend to watch some Unity Tutorials on the Scripting API.

Try Following

DECLARE @formatted_datetime char(23)
SET @formatted_datetime = CONVERT(char(23), GETDATE(), 121)
print @formatted_datetime

You are plotting all your images on one axis. What you want ist to get a handle for each axis individually and plot your images there. Like so:

fig = plt.figure()
ax1 = fig.add_subplot(2,2,1)
ax1.imshow(...)
ax2 = fig.add_subplot(2,2,2)
ax2.imshow(...)
ax3 = fig.add_subplot(2,2,3)
ax3.imshow(...)
ax4 = fig.add_subplot(2,2,4)
ax4.imshow(...)

For more info have a look here: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

For complex layouts, you should consider using gridspec: http://matplotlib.org/users/gridspec.html

import os

destdir = '/var/tmp/testdir'

files = [ f for f in os.listdir(destdir) if os.path.isfile(os.path.join(destdir,f)) ]

Edit your .bowerrc file ( should be next to your bower.json file ) and add the wanted proxy configuration

"proxy":"http://<host>:<port>",
"https-proxy":"http://<host>:<port>"

running brew update and then brew install postgresql worked for me, I was able to run the pg gem file no problem after that.

If you are working on a windows forms project you can try the following:

Add items to the ListBox as KeyValuePair objects:

listBox.Items.Add(new KeyValuePair(key, value);

Then you will be able to retrieve them the following way:

KeyValuePair keyValuePair = listBox.Items[index];
var value = keyValuePair.Value;

The problem is that you used the select option, this is where you went wrong. Select signifies that a textbox or textArea has a focus. What you need to do is use change. "Fires when a new choice is made in a select element", also used like blur when moving away from a textbox or textArea.

function start(){
      document.getElementById("activitySelector").addEventListener("change", addActivityItem, false);
      }

function addActivityItem(){
      //option is selected
      alert("yeah");
}

window.addEventListener("load", start, false);

Apart from the DATEDIFF you can also use the TIMEDIFF function or the TIMESTAMPDIFF.

EXAMPLE

SET @date1 = '2010-10-11 12:15:35', @date2 = '2010-10-10 00:00:00';

SELECT 
TIMEDIFF(@date1, @date2) AS 'TIMEDIFF',
TIMESTAMPDIFF(hour, @date1, @date2) AS 'Hours',
TIMESTAMPDIFF(minute, @date1, @date2) AS 'Minutes',
TIMESTAMPDIFF(second, @date1, @date2) AS 'Seconds';

RESULTS

TIMEDIFF : 36:15:35
Hours : -36
Minutes : -2175
Seconds : -130535

actually, your answer is not complete as the values also depend on the wrapping container. In case of relative or linear layouts, the values behave like this:

• EXACTLY match_parent is EXACTLY + size of the parent
• AT_MOST wrap_content results in an AT_MOST MeasureSpec
• UNSPECIFIED never triggered

In case of an horizontal scroll view, your code will work.

Cloud: is simply an aggregate of computing power. You can think of the entire "cloud" as single server, for your purposes. It's conceptually much like an old school mainframe where you could submit your jobs to and have it return the result, except that nowadays the concept is applied more widely. (I.e. not just raw computing, also entire services, or storage ...)

Grid: a grid is simply many computers which together might solve a given problem/crunch data. The fundamental difference between a grid and a cluster is that in a grid each node is relatively independent of others; problems are solved in a divide and conquer fashion.

Cluster: conceptually it is essentially smashing up many machines to make a really big & powerful one. This is a much more difficult architecture than cloud or grid to get right because you have to orchestrate all nodes to work together, and provide consistency of things such as cache, memory, and not to mention clocks. Of course clouds have much the same problem, but unlike clusters clouds are not conceptually one big machine, so the entire architecture doesn't have to treat it as such. You can for instance not allocate the full capacity of your data center to a single request, whereas that is kind of the point of a cluster: to be able to throw 100% of the oomph at a single problem.

class Hello(Gtk.Window):

    def __init__(self):
        super(Hello, self).__init__()
        clipboard = Gtk.Clipboard.get(Gdk.SELECTION_CLIPBOARD)
        clipboard.set_text("hello world", -1)
        Gtk.main_quit()

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

Here is how you should do it:

review.forEach(function(p,index,object){
   if(review[index] === '\u2022 \u2022 \u2022'){
      console.log('YippeeeE!!!!!!!!!!!!!!!!')
      review.splice(index, 1);
   }
});

Try this (i use background and background-color in this example):

var ClickEventType = ((document.ontouchstart !== null) ? 'click' : 'touchstart');

if (ClickEventType == 'touchstart') {
            $('a').each(function() { // save original..
                var back_color = $(this).css('background-color');
                var background = $(this).css('background');
                $(this).attr('data-back_color', back_color);
                $(this).attr('data-background', background);
            });

            $('a').on('touchend', function(e) { // overwrite with original style..
                var background = $(this).attr('data-background');
                var back_color = $(this).attr('data-back_color');
                if (back_color != undefined) {
                    $(this).css({'background-color': back_color});
                }
                if (background != undefined) {
                    $(this).css({'background': background});
                }
            }).on('touchstart', function(e) { // clear added stlye="" elements..
                $(this).css({'background': '', 'background-color': ''});
            });
}

css:

a {
    -webkit-touch-callout: none;
    -webkit-tap-highlight-color: transparent;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

With below converter

public class CustomDateTimeConverter : IsoDateTimeConverter
    {
        public CustomDateTimeConverter()
        {
            DateTimeFormat = "yyyy-MM-dd";
        }

        public CustomDateTimeConverter(string format)
        {
            DateTimeFormat = format;
        }
    }

Can use it with a default custom format

class ReturnObjectA 
{
    [JsonConverter(typeof(DateFormatConverter))]
    public DateTime ReturnDate { get;set;}
}

Or any specified format for a property

class ReturnObjectB 
{
    [JsonConverter(typeof(DateFormatConverter), "dd MMM yy")]
    public DateTime ReturnDate { get;set;}
}

If you're working within a complex page with existing mouse event handlers, I'd recommend handling the event on capture (instead of bubble). To do this, just set the 3rd parameter of addEventListener to true.

Additionally, you may want to check for event.which to ensure you're handling actual user interaction and not mouse events, e.g. elem.dispatchEvent(new Event('mousedown')).

var isMouseDown = false;

document.addEventListener('mousedown', function(event) { 
    if ( event.which ) isMouseDown = true;
}, true);

document.addEventListener('mouseup', function(event) { 
    if ( event.which ) isMouseDown = false;
}, true);

Add the handler to document (or window) instead of document.body is important b/c it ensures that mouseup events outside of the window are still recorded.

Sounds like you need to add the formatting to the WHERE:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE_FORMAT(users.signup_date, '%Y-%m-%d') = CURDATE()

See SQL Fiddle with Demo

It looks like you can simply do:

SELECT * FROM your_table WHERE some_column IS NULL OR some_column = '';

Test case:

CREATE TABLE your_table (id int, some_column varchar(10));

INSERT INTO your_table VALUES (1, NULL);
INSERT INTO your_table VALUES (2, '');
INSERT INTO your_table VALUES (3, 'test');
INSERT INTO your_table VALUES (4, 'another test');
INSERT INTO your_table VALUES (5, NULL);

Result:

SELECT id FROM your_table WHERE some_column IS NULL OR some_column = '';

id        
----------
1         
2         
5    

length is a property, not a method. You can't call it, hence you don't need parenthesis ():

function getlength(number) {
    return number.toString().length;
}

UPDATE: As discussed in the comments, the above example won't work for float numbers. To make it working we can either get rid of a period with String(number).replace('.', '').length, or count the digits with regular expression: String(number).match(/\d/g).length.

In terms of speed potentially the fastest way to get number of digits in the given number is to do it mathematically. For positive integers there is a wonderful algorithm with log10:

var length = Math.log(number) * Math.LOG10E + 1 | 0;  // for positive integers

For all types of integers (including negatives) there is a brilliant optimised solution from @Mwr247, but be careful with using Math.log10, as it is not supported by many legacy browsers. So replacing Math.log10(x) with Math.log(x) * Math.LOG10E will solve the compatibility problem.

Creating fast mathematical solutions for decimal numbers won't be easy due to well known behaviour of floating point math, so cast-to-string approach will be more easy and fool proof. As mentioned by @streetlogics fast casting can be done with simple number to string concatenation, leading the replace solution to be transformed to:

var length = (number + '').replace('.', '').length;  // for floats

Same as what @NullUserException said, this is how I write it:

removedWhitespce = re.sub(r'^\s*$', '', line)

@Override
    public boolean onTouch(View v, MotionEvent event) {
       float x = event.getX();
       float y = event.getY();
       return true;
    }

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

Ctrl+H.

Also,

• Open any file quickly without browsing for it in the Package Explorer: Ctrl + Shift + R.

• Open a type (e.g.: a class, an interface) without clicking through interminable list of packages: Ctrl + Shift + T.

• Go directly to a member (method, variable) of a huge class file, especially when a lot of methods are named similarly: Ctrl + O

• Go to line number N in the source file: Ctrl + L, enter line number.

Using task scheduler, schedule a run of CMDKEY running under SYSTEM with the appropriate arguments of /add: /user: and /pass:

No need to install anything.

• Check that your users.gender column is an INTEGER.
• Try: alter table users convert to character set latin1 collate latin1_swedish_ci;

In the __init__ method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called.

self, as a name, is just a convention, call it as you want ! but when using it, for example to delete the object, you have to use the same name: __del__(var), where var was used in the __init__(var,[...])

You should take a look at cls too, to have the bigger picture. This post could be helpful.

Example: fileA and fileB - start in fileA at line 25, copy 50 lines, and paste to fileB

fileA

Goto 25th line

copy 50 lines into buffer v

Goto fileB

:e fileB

Goto line 10

Yes, it means unsigned int. It used to be that if you didn't specify a data type in C there were many places where it just assumed int. This was try, for example, of function return types.

This wart has mostly been eradicated, but you are encountering its last vestiges here. IMHO, the code should be fixed to say unsigned int to avoid just the sort of confusion you are experiencing.

https://support.procore.com/faq/what-is-the-difference-between-sp-and-idp-initiated-sso

There is much more to this but this is a high level overview on which is which.

Procore supports both SP- and IdP-initiated SSO:

Identity Provider Initiated (IdP-initiated) SSO. With this option, your end users must log into your Identity Provider's SSO page (e.g., Okta, OneLogin, or Microsoft Azure AD) and then click an icon to log into and open the Procore web application. To configure this solution, see Configure IdP-Initiated SSO for Microsoft Azure AD, Configure Procore for IdP-Initated Okta SSO, or Configure IdP-Initiated SSO for OneLogin. OR Service Provider Initiated (SP-initiated) SSO. Referred to as Procore-initiated SSO, this option gives your end users the ability to sign into the Procore Login page and then sends an authorization request to the Identify Provider (e.g., Okta, OneLogin, or Microsoft Azure AD). Once the IdP authenticates the user's identify, the user is logged into Procore. To configure this solution, see Configure Procore-Initiated SSO for Microsoft Azure Active Directory, Configure Procore-Initiated SSO for Okta, or Configure Procore-Initiated SSO for OneLogin.

This answer covers a lot of ground, so it’s divided into three parts:

• How to use a CORS proxy to get around “No Access-Control-Allow-Origin header” problems
• How to avoid the CORS preflight
• How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

How to use a CORS proxy to avoid “No Access-Control-Allow-Origin header” problems

If you don’t control the server your frontend code is sending a request to, and the problem with the response from that server is just the lack of the necessary Access-Control-Allow-Origin header, you can still get things to work—by making the request through a CORS proxy.

You can easily run your own proxy using code from https://github.com/Rob--W/cors-anywhere/.
You can also easily deploy your own proxy to Heroku in just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master

After running those commands, you’ll end up with your own CORS Anywhere server running at, e.g., https://cryptic-headland-94862.herokuapp.com/.

Now, prefix your request URL with the URL for your proxy:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

How to avoid the CORS preflight

The code in the question triggers a CORS preflight—since it sends an Authorization header.

https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Preflighted_requests

Even without that, the Content-Type: application/json header would also trigger a preflight.

What “preflight” means: before the browser tries the POST in the code in the question, it’ll first send an OPTIONS request to the server — to determine if the server is opting-in to receiving a cross-origin POST that has Authorization and Content-Type: application/json headers.

It works pretty well with a small curl script - I get my data.

To properly test with curl, you must emulate the preflight OPTIONS request the browser sends:

curl -i -X OPTIONS -H "Origin: http://127.0.0.1:3000" \
    -H 'Access-Control-Request-Method: POST' \
    -H 'Access-Control-Request-Headers: Content-Type, Authorization' \
    "https://the.sign_in.url"

…with https://the.sign_in.url replaced by whatever your actual sign_in URL is.

The response the browser needs to see from that OPTIONS request must have headers like this:

Access-Control-Allow-Origin:  http://127.0.0.1:3000
Access-Control-Allow-Methods: POST
Access-Control-Allow-Headers: Content-Type, Authorization

If the OPTIONS response doesn’t include those headers, then the browser will stop right there and never even attempt to send the POST request. Also, the HTTP status code for the response must be a 2xx—typically 200 or 204. If it’s any other status code, the browser will stop right there.

The server in the question is responding to the OPTIONS request with a 501 status code, which apparently means it’s trying to indicate it doesn’t implement support for OPTIONS requests. Other servers typically respond with a 405 “Method not allowed” status code in this case.

So you’re never going to be able to make POST requests directly to that server from your frontend JavaScript code if the server responds to that OPTIONS request with a 405 or 501 or anything other than a 200 or 204 or if doesn’t respond with those necessary response headers.

The way to avoid triggering a preflight for the case in the question would be:

• if the server didn’t require an Authorization request header but instead, e.g., relied on authentication data embedded in the body of the POST request or as a query param
• if the server didn’t require the POST body to have a Content-Type: application/json media type but instead accepted the POST body as application/x-www-form-urlencoded with a parameter named json (or whatever) whose value is the JSON data

How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

I am getting another error message:

The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://127.0.0.1:3000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

For a request that includes credentials, browsers won’t let your frontend JavaScript code access the response if the value of the Access-Control-Allow-Origin response header is *. Instead the value in that case must exactly match your frontend code’s origin, http://127.0.0.1:3000.

See Credentialed requests and wildcards in the MDN HTTP access control (CORS) article.

If you control the server you’re sending the request to, then a common way to deal with this case is to configure the server to take the value of the Origin request header, and echo/reflect that back into the value of the Access-Control-Allow-Origin response header; e.g., with nginx:

add_header Access-Control-Allow-Origin $http_origin

But that’s just an example; other (web) server systems provide similar ways to echo origin values.

I am using Chrome. I also tried using that Chrome CORS Plugin

That Chrome CORS plugin apparently just simplemindedly injects an Access-Control-Allow-Origin: * header into the response the browser sees. If the plugin were smarter, what it would be doing is setting the value of that fake Access-Control-Allow-Origin response header to the actual origin of your frontend JavaScript code, http://127.0.0.1:3000.

So avoid using that plugin, even for testing. It’s just a distraction. To test what responses you get from the server with no browser filtering them, you’re better off using curl -H as above.

As far as the frontend JavaScript code for the fetch(…) request in the question:

headers.append('Access-Control-Allow-Origin', 'http://localhost:3000');
headers.append('Access-Control-Allow-Credentials', 'true');

Remove those lines. The Access-Control-Allow-* headers are response headers. You never want to send them in a request. The only effect that’ll have is to trigger a browser to do a preflight.

The usual way is to use zip():

for x, y in zip(a, b):
    # x is from a, y is from b

This will stop when the shorter of the two iterables a and b is exhausted. Also worth noting: itertools.izip() (Python 2 only) and itertools.izip_longest() (itertools.zip_longest() in Python 3).

First you have to get the localVisible rectangle of the view

For eg:

Rect rectf = new Rect();

//For coordinates location relative to the parent
anyView.getLocalVisibleRect(rectf);

//For coordinates location relative to the screen/display
anyView.getGlobalVisibleRect(rectf);

Log.d("WIDTH        :", String.valueOf(rectf.width()));
Log.d("HEIGHT       :", String.valueOf(rectf.height()));
Log.d("left         :", String.valueOf(rectf.left));
Log.d("right        :", String.valueOf(rectf.right));
Log.d("top          :", String.valueOf(rectf.top));
Log.d("bottom       :", String.valueOf(rectf.bottom));

Hope this will help

EDIT:

To Be Clear: If the order of your #includes matters and it is not part of your design pattern (read: you don't know why), then you need to rethink your design. Most likely, this just means you need to add the #include to the header file causing problems.

At this point, I have little interest in discussing/defending the merits of the example but will leave it up as it illustrates some nuances in the compilation process and why they result in errors.

END EDIT

You need to #include the stdint.h BEFORE you #include any other library interfaces that need it.

Example:

My LCD library uses uint8_t types. I wrote my library with an interface (Display.h) and an implementation (Display.c)

In display.c, I have the following includes.

#include <stdint.h>
#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>

And this works.

However, if I re-arrange them like so:

#include <string.h>
#include <avr/io.h>
#include <Display.h>
#include <GlobalTime.h>
#include <stdint.h>

I get the error you describe. This is because Display.h needs things from stdint.h but can't access it because that information is compiled AFTER Display.h is compiled.

So move stdint.h above any library that need it and you shouldn't get the error anymore.

Try to use rbindlist approach over rbind as it's very, very fast.

Example:

library(data.table)

##### example 1: slow processing ######

table.1 <- data.frame(x = NA, y = NA)
time.taken <- 0
for( i in 1:100) {
  start.time = Sys.time()
  x <- rnorm(100)
  y <- x/2 +x/3
  z <- cbind.data.frame(x = x, y = y)

  table.1 <- rbind(table.1, z)
  end.time <- Sys.time()
  time.taken  <- (end.time - start.time) + time.taken

}
print(time.taken)
> Time difference of 0.1637917 secs

####example 2: faster processing #####

table.2 <- list()
t0 <- 0
for( i in 1:100) {
  s0 = Sys.time()
  x <- rnorm(100)
  y <- x/2 + x/3

  z <- cbind.data.frame(x = x, y = y)

  table.2[[i]] <- z

  e0 <- Sys.time()
  t0  <- (e0 - s0) + t0

}
s1 = Sys.time()
table.3 <- rbindlist(table.2)
e1 = Sys.time()

t1  <- (e1-s1) + t0
t1
> Time difference of 0.03064394 secs

You should add next permission:

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

And then here is usages in code:

val externalFilesDir = context.getExternalFilesDir(DIRECTORY_DOWNLOADS)

The ODP.Net provider from oracle uses bind by position as default. To change the behavior to bind by name. Set property BindByName to true. Than you can dismiss the double definition of parameters.

using(OracleCommand cmd = con.CreateCommand()) {
    ...
    cmd.BindByName = true;
    ...
}

You can either: Write a server-side script page like PHP, JSP, ASP.net etc to generate this HTML dynamically

or

Setup the web-server that you are using (e.g. Apache) to do exactly that automatically for directories that doesn't contain welcome-page (e.g. index.html)

Specifically in apache read more here: Edit the httpd.conf: http://justlinux.com/forum/showthread.php?s=&postid=502789#post502789 (updated link: https://forums.justlinux.com/showthread.php?94230-Make-apache-list-directory-contents&highlight=502789)

or add the autoindex mod: http://httpd.apache.org/docs/current/mod/mod_autoindex.html

why kill -9 : the number 9 in the list of signals has been chosen to be SIGKILL in reference to "kill the 9 lives of a cat".

If you already use Angular, then you could profit $filter('date').

For example:

var myDate = new Date();
var myWeek = $filter('date')(myDate, 'ww');

I've heard good things about Eigen and NT2, but haven't personally used either. There's also Boost.UBLAS, which I believe is getting a bit long in the tooth. The developers of NT2 are building the next version with the intention of getting it into Boost, so that might count for somthing.

My lin. alg. needs don't exteed beyond the 4x4 matrix case, so I can't comment on advanced functionality; I'm just pointing out some options.

Did you try -v (or --verbose) option for git commit? It adds the diff of the commit in the message editor.

Just recently I wrote something like this in Node called markdown-include that allows you to include markdown files with C style syntax, like so:

#include "my-file.md"

I believe this aligns nicely with the question you're asking. I know this an old one, but I wanted to update it at least.

You can include this in any markdown file you wish. That file can also have more includes and markdown-include will make an internal link and do all of the work for you.

You can download it via npm

npm install -g markdown-include

This would do it.

     public static void main(String[] args) {
        double d = 12.349678;
        int r = (int) Math.round(d*100);
        double f = r / 100.0;
       System.out.println(f);
     }

You can short this method, it's easy to understand that's why I have written like this.

Five ways, 4 for bash and 1 addition for zsh:

• type foobar &> /dev/null
• hash foobar &> /dev/null
• command -v foobar &> /dev/null
• which foobar &> /dev/null
• (( $+commands[foobar] )) (zsh only)

You can put any of them to your if clause. According to my tests (https://www.topbug.net/blog/2016/10/11/speed-test-check-the-existence-of-a-command-in-bash-and-zsh/), the 1st and 3rd method are recommended in bash and the 5th method is recommended in zsh in terms of speed.

The easiest option to do that is running a VM with a OSX copy.

Jon Perryman,

Yes JS can read local files (see FileReader()) but not automatically: the user has to pass the file or a list of files to the script with an html <input type="file">.

Then with JS it is possible to process (example view) the file or the list of files, some of their properties and the file or files content.

What JS cannot do for security reasons is to access automatically (without the user input) to the filesystem of his computer.

To allow JS to access to the local fs automatically is needed to create not an html file with JS inside it but an hta document.

An hta file can contain JS or VBS inside it.

But the hta executable will work on windows systems only.

This is standard browser behavior.

Also Google Chrome worked at the fs API, more info here: http://www.html5rocks.com/en/tutorials/file/filesystem/

Give A Try Like this

    result = spark.createDataFrame([('SpeciesId','int'), ('SpeciesName','string')],["col_name", "data_type"]); 
    for f in result.collect(): 
        print (f.col_name)

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

One of the advantages of the static factory methods with private constructor(object creation must have been restricted for external classes to ensure instances are not created externally) is that you can create instance-controlled classes. And instance-controlled classes guarantee that no two equal distinct instances exist(a.equals(b) if and only if a==b) during your program is running that means you can check equality of objects with == operator instead of equals method, according to Effective java.

The ability of static factory methods to return the same object from repeated invocations allows classes to maintain strict control over what instances exist at any time. Classes that do this are said to be instance-controlled. There are several reasons to write instance-controlled classes. Instance control allows a class to guarantee that it is a singleton (Item 3) or noninstantiable (Item 4). Also, it allows an immutable class (Item 15) to make the guarantee that no two equal instances exist: a.equals(b) if and only if a==b. If a class makes this guarantee, then its clients can use the == operator instead of the equals(Object) method, which may result in improved performance. Enum types (Item 30) provide this guarantee.

From Effective Java, Joshua Bloch(Item 1,page 6)

I personally decided to use the ng-class attribute rather than the ng-show. I've had a lot more success going this route especially for pop-up windows that are always not shown by default.

What used to be <div class="options-modal" ng-show="showOptions"></div>

is now: <div class="options-modal" ng-class="{'show': isPrintModalShown}">

with the CSS for the options-modal class being display: none by default. The show class contains the display:block CSS.

You can also use the Properties class

Here's the constants file called

# this will hold all of the constants
frameWidth = 1600
frameHeight = 900

Here is the code that uses the constants

public class SimpleGuiAnimation {

    int frameWidth;
    int frameHeight;


    public SimpleGuiAnimation() {
        Properties properties = new Properties();

        try {
            File file = new File("src/main/resources/dataDirectory/gui_constants.properties");
            FileInputStream fileInputStream = new FileInputStream(file);
            properties.load(fileInputStream);
        }
        catch (FileNotFoundException fileNotFoundException) {
            System.out.println("Could not find the properties file" + fileNotFoundException);
        }
        catch (Exception exception) {
            System.out.println("Could not load properties file" + exception.toString());
        }


        this.frameWidth = Integer.parseInt(properties.getProperty("frameWidth"));
        this.frameHeight = Integer.parseInt(properties.getProperty("frameHeight"));
    }

Use:

(summary(fit))$coefficients[***num***,4]

where num is a number which denotes the row of the coefficients matrix. It will depend on how many features you have in your model and which one you want to pull out the p-value for. For example, if you have only one variable there will be one p-value for the intercept which will be [1,4] and the next one for your actual variable which will be [2,4]. So your num will be 2.

This answer is for creating AVD in Android Studio.

1. First click on AVD button on your Android Studio top bar.

2. In this window click on Create Virtual Device

3. Now you will choose hardware profile for AVD and click Next.

4. Choose Android Api Version you want in your AVD. Download if no api exist. Click next.

5. This is now window for customizing some AVD feature like camera, network, memory and ram size etc. Just keep default and click Finish.

6. You AVD is ready, now click on AVD button in Android Studio (same like 1st step). Then you will able to see created AVD in list. Click on Play button on your AVD.

7. Your AVD will start soon.

divs shouldn't be used for tabular data. That is just as wrong as using tables for layout.
Use a <table>. Its easy, semantically correct, and you'll be done in 5 minutes.

To expand on Keith's already amazing answer:

Custom warning messages

To allow custom warning messages, you can wrap it in a function like this:

function preventNavigation(message) {
    var confirmOnPageExit = function (e) {
        // If we haven't been passed the event get the window.event
        e = e || window.event;

        // For IE6-8 and Firefox prior to version 4
        if (e)
        {
            e.returnValue = message;
        }

        // For Chrome, Safari, IE8+ and Opera 12+
        return message;
    };
    window.onbeforeunload = confirmOnPageExit;
}

Then just call that function with your custom message:

preventNavigation("Baby, please don't go!!!");

Enabling navigation again

To re-enable navigation, all you need to do is set window.onbeforeunload to null. Here it is, wrapped in a neat little function that can be called anywhere:

function enableNavigation() {
    window.onbeforeunload = null;
}

Using jQuery to bind this to form elements

If using jQuery, this can easily be bound to all of the elements of a form like this:

$("#yourForm :input").change(function() {
    preventNavigation("You have not saved the form. Any \
        changes will be lost if you leave this page.");
});

Then to allow the form to be submitted:

$("#yourForm").on("submit", function(event) {
    enableNavigation();
});

Dynamically-modified forms:

preventNavigation() and enableNavigation() can be bound to any other functions as needed, such as dynamically modifying a form, or clicking on a button that sends an AJAX request. I did this by adding a hidden input element to the form:

<input id="dummy_input" type="hidden" />

Then any time I want to prevent the user from navigating away, I trigger the change on that input to make sure that preventNavigation() gets executed:

function somethingThatModifiesAFormDynamically() {

    // Do something that modifies a form

    // ...
    $("#dummy_input").trigger("change");
    // ...
}

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

A cleaner example using MutationObserver:

new MutationObserver( mutation => {
    if (!mutation.addedNodes) return
    mutation.addedNodes.forEach( node => {
        // do stuff with node
    })
})

Use the SQLite keyword default

db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" 
    + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
    + KEY_NAME + " TEXT NOT NULL, "
    + KEY_WORKED + " INTEGER, "
    + KEY_NOTE + " INTEGER DEFAULT 0);");

This link is useful: http://www.sqlite.org/lang_createtable.html

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

I had the same error in my case was when I needed to update jdk 7 to jdk 8, and my bad was just I installed jdk8 and I never installed jre8, only that, the error was solved immediately when I installed jre8.

I would add the following code to the accepted answer

public static class Retry<TException> where TException : Exception //ability to pass the exception type
    {
        //same code as the accepted answer ....

        public static T Do<T>(Func<T> action, TimeSpan retryInterval, int retryCount = 3)
        {
            var exceptions = new List<Exception>();

            for (int retry = 0; retry < retryCount; retry++)
            {
                try
                {
                    return action();
                }
                catch (TException ex) //Usage of the exception type
                {
                    exceptions.Add(ex);
                    Thread.Sleep(retryInterval);
                }
            }

            throw new AggregateException(String.Format("Failed to excecute after {0} attempt(s)", retryCount), exceptions);
        }
    }

Basically the above code is making the Retry class generic so you can pass the type of the exception you want to catch for retry.

Now use it almost in the same way but specifying the exception type

Retry<EndpointNotFoundException>.Do(() => SomeFunctionThatCanFail(), TimeSpan.FromSeconds(1));

According to : https://stackoverflow.com/a/24403519/365229

This should work, with plain Javascript:

var myVideo = document.getElementById('myVideoTag');

myVideo.play();
if (typeof(myVideo.webkitEnterFullscreen) != "undefined") {
    // This is for Android Stock.
    myVideo.webkitEnterFullscreen();
} else if (typeof(myVideo.webkitRequestFullscreen)  != "undefined") {
    // This is for Chrome.
    myVideo.webkitRequestFullscreen();
} else if (typeof(myVideo.mozRequestFullScreen)  != "undefined") {
    myVideo.mozRequestFullScreen();
}

You have to trigger play() before the fullscreen instruction, otherwise in Android Browser it will just go fullscreen but it will not start playing. Tested with the latest version of Android Browser, Chrome, Safari.

I've tested it on Android 2.3.3 & 4.4 browser.

This answer will do what you need, although usually you don't add specific usernames to sudoers. Instead, you have a group of sudoers and just add your user to that group when needed. This way you don't need to use visudo more than once when giving sudo permission to users.

If you're on Ubuntu, the group is most probably already set up and called admin:

$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#

...

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

On other distributions, like Arch and some others, it's usually called wheel and you may need to set it up: Arch Wiki

To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line: %wheel ALL=(ALL) ALL

Also note that on most systems visudo will read the EDITOR environment variable or default to using vi. So you can try to do EDITOR=vim visudo to use vim as the editor.

To add a user to the group you should run (as root):

# usermod -a -G groupname username

where groupname is your group (say, admin or wheel) and username is the username (say, john).

Here is a simpler solution to list all files in a directory and to download it.

In your index.php file

<?php
$dir = "./";

$allFiles = scandir($dir);
$files = array_diff($allFiles, array('.', '..')); // To remove . and .. 

foreach($files as $file){
     echo "<a href='download.php?file=".$file."'>".$file."</a><br>";
}

The scandir() function list all files and directories inside the specified path. It works with both PHP 5 and PHP 7.

Now in the download.php

<?php
$filename = basename($_GET['file']);
// Specify file path.
$path = ''; // '/uplods/'
$download_file =  $path.$filename;

if(!empty($filename)){
    // Check file is exists on given path.
    if(file_exists($download_file))
    {
      header('Content-Disposition: attachment; filename=' . $filename);  
      readfile($download_file); 
      exit;
    }
    else
    {
      echo 'File does not exists on given path';
    }
 }

Alternatively you can create a new scope and pass through params via the scope option

var scope = $rootScope.$new();
 scope.params = {editId: $scope.editId};
    $modal.open({
        scope: scope,
        templateUrl: 'template.html',
        controller: 'Controller',
    });

In your modal controller pass in $scope, you then do not need to pass in and itemsProvider or what ever resolve you named it

modalController = function($scope) {
    console.log($scope.params)
}

You can get detail error by using responseText property.

$.ajaxSetup({
error: function(xhr, status, error) {
alert("An AJAX error occured: " + status + "\nError: " + error + "\nError detail: " + xhr.responseText);
     } 
    });

It's valid to omit them in HTML4:

7.3 The HTML element
start tag: optional, End tag: optional

7.4.1 The HEAD element
start tag: optional, End tag: optional

http://www.w3.org/TR/html401/struct/global.html

In HTML5, there are no "required" or "optional" elements exactly, as HTML5 syntax is more loosely defined. For example, title:

The title element is a required child in most situations, but when a higher-level protocol provides title information, e.g. in the Subject line of an e-mail when HTML is used as an e-mail authoring format, the title element can be omitted.

http://www.w3.org/TR/html5/semantics.html#the-title-element-0

It's not valid to omit them in true XHTML5, though that is almost never used (versus XHTML-acting-like-HTML5).

However, from a practical standpoint you often want browsers to run in "standards mode," for predictability in rendering HTML and CSS. Providing a DOCTYPE and a more structured HTML tree will guarantee more predictable cross-browser results.

It is bad practice to catch Exception -- it's just too broad, and you may miss something like a NullPointerException in your own code.

For most file operations, IOException is the root exception. Better to catch that, instead.

Places is a list and not a dictionary. This line below should therefore not work:

print data['places']['latitude']

You need to select one of the items in places and then you can list the place's properties. So to get the first post code you'd do:

print data['places'][0]['post code']

Possible solutions is put your dependencies in src/main/resources then in your pom :

<dependency>
groupId ...
artifactId ...
version ...
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/yourJar.jar</systemPath>
</dependency>

Note: system dependencies are not copied into resulted jar/war
(see How to include system dependencies in war built using maven)

Actually, all this is clearly described in Java docs (but I realized this only after reading the answers).

http://docs.oracle.com/javase/8/docs/api/index.html :

wait() - The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until another thread notifies threads waiting on this object's monitor to wake up either through a call to the notify method or the notifyAll method. The thread then waits until it can re-obtain ownership of the monitor and resumes execution.

sleep() - Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds, subject to the precision and accuracy of system timers and schedulers. The thread does not lose ownership of any monitors.

if the system you use is CentOS/RedHat, and rpm is the way you install MySQL, there is no my.cnf in /etc/ folder, you could use: #whereis mysql #cd /usr/share/mysql/ cp -f /usr/share/mysql/my-medium.cnf /etc/my.cnf

If you don't prefer LINQ, it is better to use foreach loop to avoid out of index.

int[] arr = new int[] { 1, 2, 3 };
int sum = 0;
foreach (var item in arr)
{
   sum += item;
}

In SQLite you should do this:

SELECT * 
FROM leftTable lt 
LEFT JOIN rightTable rt ON lt.id = rt.lrid 
UNION
SELECT lt.*, rl.*  -- To match column set
FROM rightTable rt 
LEFT JOIN  leftTable lt ON lt.id = rt.lrid

Try using dynamic SQL:

create procedure sp_First @columnname varchar 
AS 
begin 
    declare @sql nvarchar(4000);
    set @sql='select ['+@columnname+'] from Table_1';
    exec sp_executesql @sql
end 
go

exec sp_First 'sname'
go

Here you can find a tool that can validate a JSON file, or you could just deserialize your JSON file with any JSON library and if the operation is successful then it should be valid (google-json for example that will throw an exception if the input it is parsing is not valid JSON).

First of all, you tried to replace the entire 12.00 with '', which isn't going to give your desired results.

Second you are trying to do replace directly on a decimal. Replace must be performed on a string, so you have to CAST.

There are many ways to get your desired results, but this replace would have worked (assuming your column name is "height":

REPLACE(CAST(height as varchar(31)),'.00','')

EDIT:

This script works:

DECLARE @Height decimal(6,2);
SET @Height = 12.00;
SELECT @Height, REPLACE(CAST(@Height AS varchar(31)),'.00','');

If you are on Xamarin and you get this error (probably because of Firebase.Crashlytics):

INSTALL_FAILED_CONFLICTING_PROVIDER
Package couldn't be installed in [...]
Can't install because provider name dollar_openBracket_applicationId_closeBracket (in package [...]]) is already used by [...]

As mentioned here, you need to update Xamarin.Build.Download:

1. Update the Xamarin.Build.Download Nuget Package to 0.4.12-preview3
   • On Mac, you may need to check Show pre-release packages in the Add Packages window
2. Close Visual Studio
3. Delete all cached locations of NuGet Packages:
   • On Windows, open Visual Studio but not the solution:
     • Tools -> Option -> Nuget Package Manager -> General -> Clear All Nuget Cache(s)
   • On Mac, wipe the following folders:
     • ~/.local/share/NuGet
     • ~/.nuget/packages
     • packages folder in solution
4. Delete bin/obj folders in solution
5. Load the Solution
6. Restore Nuget Packages for the Solution (should run automatically)
7. Rebuild

Try PHP's "get_headers" function.

Something along the lines of:

<?php
    $url = 'http://www.example.com';
    print_r(get_headers($url));
    print_r(get_headers($url, 1));
?>

if(strcmp(aString, bString) == 0){
    //strings are the same
}

Here is an actual *nix equivalent, i.e. it gives *nix-style output.

Get-Command <your command> | Select-Object -ExpandProperty Definition

Just replace with whatever you're looking for.

PS C:\> Get-Command notepad.exe | Select-Object -ExpandProperty Definition
C:\Windows\system32\notepad.exe

When you add it to your profile, you will want to use a function rather than an alias because you can't use aliases with pipes:

function which($name)
{
    Get-Command $name | Select-Object -ExpandProperty Definition
}

Now, when you reload your profile you can do this:

PS C:\> which notepad
C:\Windows\system32\notepad.exe

• npm install installs the depedendencies in your package.json config.
• npm run build runs the script "build" and created a script which runs your application - let's say server.js
• npm start runs the "start" script which will then be "node server.js"

It's difficult to tell exactly what the issue was but basically if you look at your scripts configuration, I would guess that "build" uses some kind of build tool to create your application while "start" assumes the build has been done but then fails if the file is not there.

You are probably using bower or grunt - I seem to remember that a typical grunt application will have defined those scripts as well as a "clean" script to delete the last build.

Build tools tend to create a file in a bin/, dist/, or build/ folder which the start script then calls - e.g. "node build/server.js". When your npm start fails, it is probably because you called npm clean or similar to delete the latest build so your application file is not present causing npm start to fail.

npm build's source code - to touch on the discussion in this question - is in github for you to have a look at if you like. If you run npm build directly and you have a "build" script defined, it will exit with an error asking you to call your build script as npm run-script build so it's not the same as npm run script.

I'm not quite sure what npm build does, but it seems to be related to postinstall and packaging scripts in dependencies. I assume that this might be making sure that any CLI build scripts's or native libraries required by dependencies are built for the specific environment after downloading the package. This will be why link and install call this script.

When I did sudo /etc/init.d/php-fpm start I got the following error:

Starting php-fpm: [28-Mar-2013 16:18:16] ERROR: [pool www] cannot get uid for user 'apache'

I guess /etc/php-fpm.d/www.conf needs to know the user that the webserver is running as and assumes it's apache when, for nginx, it's actually nginx, and needs to be changed.

The role you have created is not allowed to log in. You have to give the role permission to log in.

One way to do this is to log in as the postgres user and update the role:

psql -U postgres

Once you are logged in, type:

ALTER ROLE "asunotest" WITH LOGIN;

An elaboration on Mundi's answer.

i.e. embedding a label in a UIView and enforcing padding through Auto Layout. Example:

Overview:

1) Create a UIView ("panel"), and set its appearance.

2) Create a UILabel and add it to the panel.

3) Add constraints to enforce padding.

4) Add the panel to your view hierarchy, then position the panel.

Details:

1) Create the panel view.

let panel = UIView()
panel.backgroundColor = .green
panel.layer.cornerRadius = 12

2) Create the label, add it to the panel as a subview.

let label = UILabel()
panel.addSubview(label)

3) Add constraints between the edges of the label and the panel. This forces the panel to keep a distance from the label. i.e. "padding"

Editorial: doing all this by hand is super-tedious, verbose and error-prone. I suggest you pick an Auto Layout wrapper from github or write one yourself

label.panel.translatesAutoresizingMaskIntoConstraints = false
label.topAnchor.constraint(equalTo: panel.topAnchor,
    constant: vPadding).isActive = true
label.bottomAnchor.constraint(equalTo: panel.bottomAnchor,
    constant: -vPadding).isActive = true
label.leadingAnchor.constraint(equalTo: panel.leadingAnchor,
    constant: hPadding).isActive = true
label.trailingAnchor.constraint(equalTo: panel.trailingAnchor,
    constant: -hPadding).isActive = true

label.textAlignment = .center

4) Add the panel to your view hierarchy and then add positioning constraints. e.g. hug the right-hand side of a tableViewCell, as in the example image.

Note: you only need to add positional constraints, not dimensional constraints: Auto Layout will solve the layout based on both the intrinsicContentSize of the label and the constraints added earlier.

hostView.addSubview(panel)
panel.translatesAutoresizingMaskIntoConstraints = false
panel.trailingAnchor.constraint(equalTo: hostView.trailingAnchor,
    constant: -16).isActive = true
panel.centerYAnchor.constraint(equalTo: hostView.centerYAnchor).isActive = true

In RSA crypto, when you generate a key pair, it's completely arbitrary which one you choose to be the public key, and which is the private key. If you encrypt with one, you can decrypt with the other - it works in both directions.

So, it's fairly simple to see how you can encrypt a message with the receiver's public key, so that the receiver can decrypt it with their private key.

A signature is proof that the signer has the private key that matches some public key. To do this, it would be enough to encrypt the message with that sender's private key, and include the encrypted version alongside the plaintext version. To verify the sender, decrypt the encrypted version, and check that it is the same as the plaintext.

Of course, this means that your message is not secret. Anyone can decrypt it, because the public key is well known. But when they do so, they have proved that the creator of the ciphertext has the corresponding private key.

However, this means doubling the size of your transmission - plaintext and ciphertext together (assuming you want people who aren't interested in verifying the signature, to read the message). So instead, typically a signature is created by creating a hash of the plaintext. It's important that fake hashes can't be created, so cryptographic hash algorithms such as SHA-2 are used.

So:

• To generate a signature, make a hash from the plaintext, encrypt it with your private key, include it alongside the plaintext.
• To verify a signature, make a hash from the plaintext, decrypt the signature with the sender's public key, check that both hashes are the same.

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

You can just add the overflow:auto option:

#second
{
   width:300px;
   height:100%;
   overflow: auto;
   background-color:#9ACD32;
}

Depending on what program you use for ssh, the way to get the proper key could vary. Putty (popular with Windows) uses their own format for ssh keys. With most variants of Linux and BSD that I've seen, you just have to look in ~/.ssh/known_hosts. I usually ssh from a Linux machine and then copy this file to a Windows machine. Then I use something similar to

jsch.setKnownHosts("C:\\Users\\cabbott\\known_hosts");

Assuming I have placed the file in C:\Users\cabbott on my Windows machine. If you don't have access to a Linux machine, try http://www.cygwin.com/

Maybe someone else can suggest another Windows alternative. I find putty's way of handling SSH keys by storing them in the registry in a non-standard format bothersome to extract.

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

Alternative solution if all above solutions are not working for you

By default, Volley set timeout equally for both setConnectionTimeout() and setReadTimeout() with the value from RetryPolicy. In my case, Volley throws timeout exception for large data chunk see:

com.android.volley.toolbox.HurlStack.openConnection(). 

My solution is create a class which extends HttpStack with my own setReadTimeout() policy. Then use it when creates RequestQueue as follow:

Volley.newRequestQueue(mContext.getApplicationContext(), new MyHurlStack())

There is a lib called jnotify that wraps inotify on linux and has also support for windows. Never used it and I don't know how good it is, but it's worth a try I'd say.

As mentioned in other answers, test.only merely filters out other tests in the same file. So tests in other files would still run.

So to run a single test, there are two approaches:

• Option 1: If your test name is unique, you can enter t while in watch mode and enter the name of the test you'd like to run.

• Option 2:

  1. Hit p while in watch mode to enter a regex for the filename you'd like to run. (Relevant commands like this are displayed when you run Jest in watch mode).
  2. Change it to it.only on the test you'd like to run.

With either of the approaches above, Jest will only run the single test in the file you've specified.

Here is how I've always done it:

    public static string Serialize(object obj) {
        using(MemoryStream memoryStream = new MemoryStream())
        using(StreamReader reader = new StreamReader(memoryStream)) {
            DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
            serializer.WriteObject(memoryStream, obj);
            memoryStream.Position = 0;
            return reader.ReadToEnd();
        }
    }

    public static object Deserialize(string xml, Type toType) {
        using(Stream stream = new MemoryStream()) {
            byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
            stream.Write(data, 0, data.Length);
            stream.Position = 0;
            DataContractSerializer deserializer = new DataContractSerializer(toType);
            return deserializer.ReadObject(stream);
        }
    }

I had an onpremises HA installation, a master and a worker stopped working returning a NOTReady status. Checking the kubelet logs on the nodes I found out this problem:

failed to run Kubelet: Running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false

Disabling swap on nodes with

swapoff -a

and restarting the kubelet

systemctl restart kubelet

did the work.

                                            Console.WriteLine("\t{0}: {1}", dataAttr.Key, dataAttr.Value);

                                        throw new Exception("Cannot recognize the message type");
                                    }

                        }
                    }
                }
            }
        }
    }
}

I think the reason that this is happening could be because TextBox1 is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".

EDIT

It looks like you may be able to use the GetObject function to pull the textbox from the workbook.

You can set max connections using:

set global max_connections = '1 < your number > 100000';

This will set your number of mysql connection unti (Requires SUPER privileges).

Use substring method like this::

str.substring(str.length()-2);

First add action command on JButton or JTextField by:

JButton.setActionCommand("name of command");
JTextField.setActionCommand("name of command");

Then add ActionListener to both JTextField and JButton.

JButton.addActionListener(listener);
JTextField.addActionListener(listener);

After that, On you ActionListener implementation write

@Override
public void actionPerformed(ActionEvent e)
{
    String actionCommand = e.getActionCommand();

    if(actionCommand.equals("Your actionCommand for JButton") || actionCommand.equals("Your   actionCommand for press Enter"))
    {
        //Do something
    }
}

With Angular CLI 6 you need to use builders as ng eject is deprecated and will soon be removed in 8.0. That's what it says when I try to do an ng eject

You can use angular-builders package (https://github.com/meltedspark/angular-builders) to provide your custom webpack config.

I have tried to summarize all in a single blog post on my blog - How to customize build configuration with custom webpack config in Angular CLI 6

but essentially you add following dependencies -

  "devDependencies": {
    "@angular-builders/custom-webpack": "^7.0.0",
    "@angular-builders/dev-server": "^7.0.0",
    "@angular-devkit/build-angular": "~0.11.0",

In angular.json make following changes -

  "architect": {
    "build": {
      "builder": "@angular-builders/custom-webpack:browser",
      "options": {
        "customWebpackConfig": {"path": "./custom-webpack.config.js"},

Notice change in builder and new option customWebpackConfig. Also change

    "serve": {
      "builder": "@angular-builders/dev-server:generic",

Notice the change in builder again for serve target. Post these changes you can create a file called custom-webpack.config.js in your same root directory and add your webpack config there.

However, unlike ng eject configuration provided here will be merged with default config so just add stuff you want to edit/add.

Likely quite simple but best way is to edit manually the file .classpath at the root of your project folder with something like

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
            <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
        </attributes>
    </classpathentry>

when you want to have jar in your WEB-IN/lib folder (case for a web app)

Try this on for size:

String properCase (String inputVal) {
    // Empty strings should be returned as-is.

    if (inputVal.length() == 0) return "";

    // Strings with only one character uppercased.

    if (inputVal.length() == 1) return inputVal.toUpperCase();

    // Otherwise uppercase first letter, lowercase the rest.

    return inputVal.substring(0,1).toUpperCase()
        + inputVal.substring(1).toLowerCase();
}

It basically handles special cases of empty and one-character string first and correctly cases a two-plus-character string otherwise. And, as pointed out in a comment, the one-character special case isn't needed for functionality but I still prefer to be explicit, especially if it results in fewer useless calls, such as substring to get an empty string, lower-casing it, then appending it as well.

As hinted at in one of the above answers, you won't get an XMLRootElement on your root element if in the XSD its type is defined as a named type, since that named type could be used elsewhere in your XSD. Try mking it an anonymous type, i.e. instead of:

<xsd:element name="myRootElement" type="MyRootElementType" />

<xsd:complexType name="MyRootElementType">
...
</xsd:complexType>

you would have:

<xsd:element name="myRootElement">
    <xsd:complexType>
    ...
    <xsd:complexType>
</xsd:element>

I use the requests library. It seems to be more robust.

from PIL import Image
import requests
from StringIO import StringIO

response = requests.get(url)
img = Image.open(StringIO(response.content))

Although this question was more specifically about IP addresses in Subject Alt. Names, the commands are similar (using DNS entries for a host name and IP entries for IP addresses).

To quote myself:

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1

Note that you only need Java 7's keytool to use this command. Once you've prepared your keystore, it should work with previous versions of Java.

(The rest of this answer also mentions how to do this with OpenSSL, but it doesn't seem to be what you're using.)

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

Sample Html code   
 <div id="temp">
        F1 <input type="text" value="111"/><br/>
        F2 <input type="text" value="222"/><br/>
        F3 <input type="text" value="333"/><br/>
        Type <select>
        <option value="A">A</option>
        <option value="B">B</option>
        <option value="C">C</option>
        </select>
        <input type="button" value="Go" onclick="getVal()">
    </div>

Javascript

    function  getVal()
    {
        var test = document.getElementById("temp").getElementsByTagName("input");
        alert("Number of Input Elements "+test.length);
        for(var i=0;i<test.length;i++)
        {
          if(test[i].type=="text")
          {
            alert(test[i].value);
          }
       }
      test = document.getElementById("temp").getElementsByTagName("select");
      alert("Select box  "+test[0].options[test[0].selectedIndex].text);
    }

By providing different tag names we can get all the values from the div.

The answers above will work for changing the values.

If you want to change the number of cells in your list (e.g. I have a list called 'revisions' which has 4 items, I now need 7 items) you will find that you can't simply select your list and amend it on the sheet, So:

go to your 'Formulas' tab

choose "Name Manager"

a pop up box will show what is available for editing. Your list should be in it. Select your list and edit the range.

my problem (git on macOS) was solved by using sudo git instead of just git in all add and commit commands

QT can be as simple as that of Windows. The equivalent code is

if (QMessageBox::Yes == QMessageBox(QMessageBox::Information, "title", "Question", QMessageBox::Yes|QMessageBox::No).exec()) 
{

}

df.info() function will give you result something like as below. If you are using read_csv method of Pandas without sep parameter or sep with ",".

raw_data = pd.read_csv("a1:\aa2/aaa3/data.csv")
raw_data.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 5144 entries, 0 to 5143
Columns: 145 entries, R_fighter to R_age

The approved solution does create unique IDs but on first glance they look identical, only the first few characters differ.

If you want visibly different keys, try this:

update CityPopCountry set id = (select md5(UUID()));

I'm using MySQL Server version: 5.5.40-0+wheezy1 (Debian)

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

I know how to create a custom row + custom array adapter to support a custom row for the entire list view. But how can one listview support many different row styles?

You already know the basics. You just need to get your custom adapter to return a different layout/view based on the row/cursor information being provided.

A ListView can support multiple row styles because it derives from AdapterView:

An AdapterView is a view whose children are determined by an Adapter.

If you look at the Adapter, you'll see methods that account for using row-specific views:

abstract int getViewTypeCount()
// Returns the number of types of Views that will be created ...

abstract int getItemViewType(int position)
// Get the type of View that will be created ...

abstract View getView(int position, View convertView, ViewGroup parent)
// Get a View that displays the data ...

The latter two methods provide the position so you can use that to determine the type of view you should use for that row.

Of course, you generally don't use AdapterView and Adapter directly, but rather use or derive from one of their subclasses. The subclasses of Adapter may add additional functionality that change how to get custom layouts for different rows. Since the view used for a given row is driven by the adapter, the trick is to get the adapter to return the desired view for a given row. How to do this differs depending on the specific adapter.

For example, to use ArrayAdapter,

• override getView() to inflate, populate, and return the desired view for the given position. The getView() method includes an opportunity reuse views via the convertView parameter.

But to use derivatives of CursorAdapter,

• override newView() to inflate, populate, and return the desired view for the current cursor state (i.e. the current "row") [you also need to override bindView so that widget can reuse views]

However, to use SimpleCursorAdapter,

• define a SimpleCursorAdapter.ViewBinder with a setViewValue() method to inflate, populate, and return the desired view for a given row (current cursor state) and data "column". The method can define just the "special" views and defer to SimpleCursorAdapter's standard behavior for the "normal" bindings.

Look up the specific examples/tutorials for the kind of adapter you end up using.

I'm late to the party, but hopefully this is a useful addition to the other answers here...

Answering the Question / tl:dr;

I need to know how I can determine what "too much work" my application may be doing as all my processing is done in AsyncTasks.

The following are all candidates:

• IO or expensive processing on the main thread (loading drawables, inflating layouts, and setting Uri's on ImageView's all constitute IO on the main thread)
• Rendering large/complex/deep View hierarchies
• Invalidating large portions of a View hierarchy
• Expensive onDraw methods in custom View's
• Expensive calculations in animations
• Running "worker" threads at too high a priority to be considered "background" (AsyncTask's are "background" by default, java.lang.Thread is not)
• Generating lots of garbage, causing the garbage collector to "stop the world" - including the main thread - while it cleans up

To actually determine the specific cause you'll need to profile your app.

More Detail

I've been trying to understand Choreographer by experimenting and looking at the code.

The documentation of Choreographer opens with "Coordinates the timing of animations, input and drawing." which is actually a good description, but the rest goes on to over-emphasize animations.

The Choreographer is actually responsible for executing 3 types of callbacks, which run in this order:

1. input-handling callbacks (handling user-input such as touch events)
2. animation callbacks for tweening between frames, supplying a stable frame-start-time to any/all animations that are running. Running these callbacks 2nd means any animation-related calculations (e.g. changing positions of View's) have already been made by the time the third type of callback is invoked...
3. view traversal callbacks for drawing the view hierarchy.

The aim is to match the rate at which invalidated views are re-drawn (and animations tweened) with the screen vsync - typically 60fps.

The warning about skipped frames looks like an afterthought: The message is logged if a single pass through the 3 steps takes more than 30x the expected frame duration, so the smallest number you can expect to see in the log messages is "skipped 30 frames"; If each pass takes 50% longer than it should you will still skip 30 frames (naughty!) but you won't be warned about it.

From the 3 steps involved its clear that it isn't only animations that can trigger the warning: Invalidating a significant portion of a large View hierarchy or a View with a complicated onDraw method might be enough.

For example this will trigger the warning repeatedly:

public class AnnoyTheChoreographerActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.simple_linear_layout);

        ViewGroup root = (ViewGroup) findViewById(R.id.root);

        root.addView(new TextView(this){
            @Override
            protected void onDraw(Canvas canvas) {
                super.onDraw(canvas);
                long sleep = (long)(Math.random() * 1000L);
                setText("" + sleep);
                try {
                    Thread.sleep(sleep);
                } catch (Exception exc) {}
            }
        });
    }
}

... which produces logging like this:

11-06 09:35:15.865  13721-13721/example I/Choreographer? Skipped 42 frames!  The application may be doing too much work on its main thread.
11-06 09:35:17.395  13721-13721/example I/Choreographer? Skipped 59 frames!  The application may be doing too much work on its main thread.
11-06 09:35:18.030  13721-13721/example I/Choreographer? Skipped 37 frames!  The application may be doing too much work on its main thread.

You can see from the stack during onDraw that the choreographer is involved regardless of whether you are animating:

at example.AnnoyTheChoreographerActivity$1.onDraw(AnnoyTheChoreographerActivity.java:25) at android.view.View.draw(View.java:13759)

... quite a bit of repetition ...

at android.view.ViewGroup.drawChild(ViewGroup.java:3169) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3039) at android.view.View.draw(View.java:13762) at android.widget.FrameLayout.draw(FrameLayout.java:467) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:2396) at android.view.View.getDisplayList(View.java:12710) at android.view.View.getDisplayList(View.java:12754) at android.view.HardwareRenderer$GlRenderer.draw(HardwareRenderer.java:1144) at android.view.ViewRootImpl.draw(ViewRootImpl.java:2273) at android.view.ViewRootImpl.performDraw(ViewRootImpl.java:2145) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1956) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1112) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:4472) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:725) at android.view.Choreographer.doCallbacks(Choreographer.java:555) at android.view.Choreographer.doFrame(Choreographer.java:525) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:711) at android.os.Handler.handleCallback(Handler.java:615) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4898)

Finally, if there is contention from other threads that reduce the amount of work the main thread can get done, the chance of skipping frames increases dramatically even though you aren't actually doing the work on the main thread.

In this situation it might be considered misleading to suggest that the app is doing too much on the main thread, but Android really wants worker threads to run at low priority so that they are prevented from starving the main thread. If your worker threads are low priority the only way to trigger the Choreographer warning really is to do too much on the main thread.

Facebook is using LAMP structure. Facebook’s back-end services are written in a variety of different programming languages including C++, Java, Python, and Erlang and they are used according to requirement. With LAMP Facebook uses some technologies ,to support large number of requests, like

1. Memcache - It is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data.

2. Thrift (protocol) - It is a lightweight remote procedure call framework for scalable cross-language services development. Thrift supports C++, PHP, Python, Perl, Java, Ruby, Erlang, and others.

3. Cassandra (database) - It is a database management system designed to handle large amounts of data spread out across many servers.

4. HipHop for PHP - It is a source code transformer for PHP script code and was created to save server resources. HipHop transforms PHP source code into optimized C++. After doing this, it uses g++ to compile it to machine code.

If we go into more detail, then answer to this question go longer. We can understand more from following posts:

2. Data Management, Facebook-style
3. Facebook database design?

The slidingExpiration=true value is basically saying that after every request made, the timer is reset and as long as the user makes a request within the timeout value, he will continue to be authenticated.

This is not correct. The authentication cookie timeout will only be reset if half the time of the timeout has passed.

See for example https://support.microsoft.com/de-ch/kb/910439/en-us or https://itworksonmymachine.wordpress.com/2008/07/17/forms-authentication-timeout-vs-session-timeout/

Since this is a popular question, I would like to add that in Elasticsearch version 2 things changed a bit.

Instead of filtered query, one should use bool query in the top level.

If you don't care about the score of must parts, then put those parts into filter key. No scoring means faster search. Also, Elasticsearch will automatically figure out, whether to cache them, etc. must_not is equally valid for caching.

Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

Also, mind that "gte": "now" cannot be cached, because of millisecond granularity. Use two ranges in a must clause: one with now/1h and another with now so that the first can be cached for a while and the second for precise filtering accelerated on a smaller result set.

You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."

Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.

Update:

The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg

Browse the repository with Firefox and inspect the element with Firebug. Under the NET tab, you can check the Header of the page. It will have something like:

Server: Apache/2.2.14 (Win32) DAV/2 SVN/1.X.X

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

You need to use preventDefault() to make it so the link does not go through when u click on it:

fiddle: http://jsfiddle.net/maniator/Sevdm/

$(function() {
 $('.menulink').click(function(e){
     e.preventDefault();
   $("#bg").attr('src',"img/picture1.jpg");
 });
});

I have this generic utility method. I pass in a list of a given type (Assuming you have a supporting class) and it generates a datatable with the properties as column headers and the list items as data.

Just like in standard MVC, if you dont have DisplayName attribute defined, it will fall back to the property name so you only have to include DisplayName where it is different to the property name.

    public DataTable BuildDataTable<T>(IList<T> data)
    {
        //Get properties
        PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        //.Where(p => !p.GetGetMethod().IsVirtual && !p.GetGetMethod().IsFinal).ToArray(); //Hides virtual properties

        //Get column headers
        bool isDisplayNameAttributeDefined = false;
        string[] headers = new string[Props.Length];
        int colCount = 0;
        foreach (PropertyInfo prop in Props)
        {
            isDisplayNameAttributeDefined = Attribute.IsDefined(prop, typeof(DisplayNameAttribute));

            if (isDisplayNameAttributeDefined)
            {
                DisplayNameAttribute dna = (DisplayNameAttribute)Attribute.GetCustomAttribute(prop, typeof(DisplayNameAttribute));
                if (dna != null)
                    headers[colCount] = dna.DisplayName;
            }
            else
                headers[colCount] = prop.Name;

            colCount++;
            isDisplayNameAttributeDefined = false;
        }

        DataTable dataTable = new DataTable(typeof(T).Name);

        //Add column headers to datatable
        foreach (var header in headers)
            dataTable.Columns.Add(header);

        dataTable.Rows.Add(headers);

        //Add datalist to datatable
        foreach (T item in data)
        {
            object[] values = new object[Props.Length];
            for (int col = 0; col < Props.Length; col++)
                values[col] = Props[col].GetValue(item, null);

            dataTable.Rows.Add(values);
        }

        return dataTable;
    }

If there's a more efficient / safer way of doing this, I'd appreicate any feedback. The commented //Where clause will filter out virtual properties. Useful if you are using model classes directly as EF puts in "Navigation" properties as virtual. However it will also filter out any of your own virtual properties if you choose to extend such classes. For this reason, I prefer to make a ViewModel and decorate it with only the needed properties and display name attributes as required, then make a list of them.

Hope this helps.

Recently had this problem but with unkown number of promises.Solved using jQuery.map().

function methodThatChainsPromises(args) {

    //var args = [
    //    'myArg1',
    //    'myArg2',
    //    'myArg3',
    //];

    var deferred = $q.defer();
    var chain = args.map(methodThatTakeArgAndReturnsPromise);

    $q.all(chain)
    .then(function () {
        $log.debug('All promises have been resolved.');
        deferred.resolve();
    })
    .catch(function () {
        $log.debug('One or more promises failed.');
        deferred.reject();
    });

    return deferred.promise;
}

• python 3.x
• unpacking with **

Use with string formatting

In addition to the answers in this thread, here is another detail that was not mentioned elsewhere. This expands on the answer by Brad Solomon

Unpacking with ** is also useful when using python str.format.

This is somewhat similar to what you can do with python f-strings f-string but with the added overhead of declaring a dict to hold the variables (f-string does not require a dict).

Quick Example

  ## init vars
  ddvars = dict()
  ddcalc = dict()
  pass
  ddvars['fname']     = 'Huomer'
  ddvars['lname']     = 'Huimpson'
  ddvars['motto']     = 'I love donuts!'
  ddvars['age']       = 33
  pass
  ddcalc['ydiff']     = 5
  ddcalc['ycalc']     = ddvars['age'] + ddcalc['ydiff']
  pass
  vdemo = []

  ## ********************
  ## single unpack supported in py 2.7
  vdemo.append('''
  Hello {fname} {lname}!

  Today you are {age} years old!

  We love your motto "{motto}" and we agree with you!
  '''.format(**ddvars)) 
  pass

  ## ********************
  ## multiple unpack supported in py 3.x
  vdemo.append('''
  Hello {fname} {lname}!

  In {ydiff} years you will be {ycalc} years old!
  '''.format(**ddvars,**ddcalc)) 
  pass

  ## ********************
  print(vdemo[-1])

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different

set month you need to date and then set the day to zero ,so month begin in 1 - 31 in date function then get the last day^^

var last = new Date(new Date(new Date().setMonth(7)).setDate(0)).getDate();_x000D_
console.log(last);

To disable (or control disabling), add the following lines to the beginning of /etc/ssh/ssh_config...

Host 192.168.0.*
   StrictHostKeyChecking=no
   UserKnownHostsFile=/dev/null

Options:

• The Host subnet can be * to allow unrestricted access to all IPs.
• Edit /etc/ssh/ssh_config for global configuration or ~/.ssh/config for user-specific configuration.

See http://linuxcommando.blogspot.com/2008/10/how-to-disable-ssh-host-key-checking.html

Similar question on superuser.com - see https://superuser.com/a/628801/55163

You can also use the addClass and removeClass methods to toggle between items such as tabs.

e.g.

if($(element).hasClass("selected"))
   $(element).removeClass("selected");

int val1 = [textBox1.text integerValue];
int val2 = [textBox2.text integerValue];

int resultValue = val1 * val2;

textBox3.text = [NSString stringWithFormat: @"%d", resultValue];

You can approach this a number of ways. If order is important you can do this:

for key in sorted(d.keys()):
  item = d.pop(key)

If order isn't a concern you can do this:

for i in range(4):
  item = d.popitem()

There is also a flag CV_VERSION which will print out the full version of opencv

In your model create the raw SQL statement (example below is an example of a date interval I had to use but substitute your own. If you are doing a SELECT add ->fetchall() to the execute() call.

   $sql = "DELETE FROM tmp 
            WHERE lastedit + INTERVAL '5 minute' < NOW() ";

    $stmt = $this->getServiceLocator()
                 ->get('Doctrine\ORM\EntityManager')
                 ->getConnection()
                 ->prepare($sql);

    $stmt->execute();

Since your task might contain asynchronous code you have to signal gulp when your task has finished executing (= "async completion").

In Gulp 3.x you could get away without doing this. If you didn't explicitly signal async completion gulp would just assume that your task is synchronous and that it is finished as soon as your task function returns. Gulp 4.x is stricter in this regard. You have to explicitly signal task completion.

You can do that in six ways:

1. Return a Stream

This is not really an option if you're only trying to print something, but it's probably the most frequently used async completion mechanism since you're usually working with gulp streams. Here's a (rather contrived) example demonstrating it for your use case:

var print = require('gulp-print');

gulp.task('message', function() {
  return gulp.src('package.json')
    .pipe(print(function() { return 'HTTP Server Started'; }));
});

The important part here is the return statement. If you don't return the stream, gulp can't determine when the stream has finished.

2. Return a Promise

This is a much more fitting mechanism for your use case. Note that most of the time you won't have to create the Promise object yourself, it will usually be provided by a package (e.g. the frequently used del package returns a Promise).

gulp.task('message', function() { 
  return new Promise(function(resolve, reject) {
    console.log("HTTP Server Started");
    resolve();
  });
});

Using async/await syntax this can be simplified even further. All functions marked async implicitly return a Promise so the following works too (if your node.js version supports it):

gulp.task('message', async function() {
  console.log("HTTP Server Started");
});

3. Call the callback function

This is probably the easiest way for your use case: gulp automatically passes a callback function to your task as its first argument. Just call that function when you're done:

gulp.task('message', function(done) {
  console.log("HTTP Server Started");
  done();
});

4. Return a child process

This is mostly useful if you have to invoke a command line tool directly because there's no node.js wrapper available. It works for your use case but obviously I wouldn't recommend it (especially since it's not very portable):

var spawn = require('child_process').spawn;

gulp.task('message', function() {
  return spawn('echo', ['HTTP', 'Server', 'Started'], { stdio: 'inherit' });
});

5. Return a RxJS Observable.

I've never used this mechanism, but if you're using RxJS it might be useful. It's kind of overkill if you just want to print something:

var of = require('rxjs').of;

gulp.task('message', function() {
  var o = of('HTTP Server Started');
  o.subscribe(function(msg) { console.log(msg); });
  return o;
});

6. Return an EventEmitter

Like the previous one I'm including this for completeness sake, but it's not really something you're going to use unless you're already using an EventEmitter for some reason.

gulp.task('message3', function() {
  var e = new EventEmitter();
  e.on('msg', function(msg) { console.log(msg); });
  setTimeout(() => { e.emit('msg', 'HTTP Server Started'); e.emit('finish'); });
  return e;
});

I was Working with Elastic SQL plugin. Query is done with GET method using cURL as below:

curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'

I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.

This code, works fine plus Basic Auth Header:

$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";

function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $host.$uri);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    if ($method == 'POST')
        curl_setopt($ch, CURLOPT_POST, 1);
    if ($auth)
        curl_setopt($ch, CURLOPT_USERPWD, $auth);
    if (strlen($data) > 0)
        curl_setopt($ch, CURLOPT_POSTFIELDS,$data);

    $resp  = curl_exec($ch);
    if(!$resp){
        $resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
    }   
    curl_close($ch);
    return $resp;
}

$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 200, 200)];

view.layer.shadowOffset = CGSizeMake(1, 0);

This is an old post, but I had a similar need and this is the solution I came up with. It is a bit of a hack, but it works and could be refined.

require 'erb'
require 'yaml'

doc = <<-EOF
  theme:
  name: default
  css_path: compiled/themes/<%= data['theme']['name'] %>
  layout_path: themes/<%= data['theme']['name'] %>
  image_path: <%= data['theme']['css_path'] %>/images
  recursive_path: <%= data['theme']['image_path'] %>/plus/one/more
EOF

data = YAML::load("---" + doc)

template = ERB.new(data.to_yaml);
str = template.result(binding)
while /<%=.*%>/.match(str) != nil
  str = ERB.new(str).result(binding)
end

puts str

A big downside is that it builds into the yaml document a variable name (in this case, "data") that may or may not exist. Perhaps a better solution would be to use $ and then substitute it with the variable name in Ruby prior to ERB. Also, just tested using hashes2ostruct which allows data.theme.name type notation which is much easier on the eyes. All that is required is to wrap the YAML::load with this

data = hashes2ostruct(YAML::load("---" + doc))

Then your YAML document can look like this

doc = <<-EOF
  theme:
  name: default
  css_path: compiled/themes/<%= data.theme.name %>
  layout_path: themes/<%= data.theme.name %>
  image_path: <%= data.theme.css_path %>/images
  recursive_path: <%= data.theme.image_path %>/plus/one/more
EOF

For checking a variable content and have a default text, you can use:

<span>{{myVar || 'Text'}}</span>

I found my solution here. Basically use an app called Proximity Screen Off Lite and set it as below:

1. Screen On/Off Modes Check "Cover and hold to turn on Screen" Timeout: 1 second Check "Disable Accidentla Lock" Timeout: 4 seconds

2. All settings Check "Disable in Lanscape" Check "Lock phone on screen ON"

3. [Advanced] Configure Sensore Select sensor: Proximity sensor Value when sensor covered: 0 Value when sensor un-covered: 1

If you need direct access:

WScript.Arguments.Item(0)
WScript.Arguments.Item(1)
...

I think Michal's answer is the best, but we can take it a step further and dynamically load an Android CSS as per the original question:

var isAndroid = /(android)/i.test(navigator.userAgent);
if (isAndroid) {
    var css = document.createElement("link");
    css.setAttribute("rel", "stylesheet");
    css.setAttribute("type", "text/css");
    css.setAttribute("href", "/css/android.css");
    document.body.appendChild(css);
}
