Enable Pytest for you project

1. Open the Settings/Preferences | Tools | Python Integrated Tools settings dialog as described in Choosing Your Testing Framework.
2. In the Default test runner field select pytest.
3. Click OK to save the settings.

in addition to all the answers that other friends have , if somebody who is looking this post is looking for a way to delete a "Folder" not a "file" , should take care that Folders must delete by php rmdir() function and if u want to delete a "Folder" by unlink() , u will encounter with a wrong Warning message that says "permission denied"

however u can make folders & files by mkdir() but the way u delete folders (rmdir()) is different from the way you delete files(unlink())

eventually as a fact:

in many programming languages, any permission related error may not directly means an actual permission issue

for example, if you want to readSync a file that doesn't exist with node fs module you will encounter a wrong EPERM error

Because QuerySets implement the Python __or__ operator (|), or union, it just works. As you'd expect, the | binary operator returns a QuerySet so order_by(), .distinct(), and other queryset filters can be tacked on to the end.

combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')

Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.

Apart from timeit which ThiefMaster mentioned, a simple way to do it is just (after importing time):

t = time.time()
# do stuff
elapsed = time.time() - t

I have a helper class I like to use:

class Timer(object):
    def __init__(self, name=None):
        self.name = name

    def __enter__(self):
        self.tstart = time.time()

    def __exit__(self, type, value, traceback):
        if self.name:
            print('[%s]' % self.name,)
        print('Elapsed: %s' % (time.time() - self.tstart))

It can be used as a context manager:

with Timer('foo_stuff'):
   # do some foo
   # do some stuff

Sometimes I find this technique more convenient than timeit - it all depends on what you want to measure.

Simple answer NO.

However you can achieve something similar by running the following version using bind variables:

SELECT * FROM Employees WHERE EmployeeID = :EmpIDVar 

Once you run the query above in SQL Developer you will be prompted to enter value for the bind variable EmployeeID.

You need allow ip based access for tomcat in server.xml, by default its disabled. Open server.xml search for "

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443" />

Here add a new attribute useIPVHosts="true" so it looks like this,

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443"
           useIPVHosts="true" />

Now restart tomcat, it should work

Complete snippet would look like the following. It expands @mouad's answer to asserting on error's message (or generally str representation of its args), which may be useful.

from unittest import TestCase


class TestNoneTypeError(TestCase):

  def setUp(self): 
    self.testListNone = None

  def testListSlicing(self):
    with self.assertRaises(TypeError) as ctx:
        self.testListNone[:1]
    self.assertEqual("'NoneType' object is not subscriptable", str(ctx.exception))

You are getting Floating point exception because Number % i, when i is 0:

int Is_Prime( int Number ){

  int i ;

  for( i = 0 ; i < Number / 2 ; i++ ){

    if( Number % i != 0 ) return -1 ;

  }

  return Number ;

}

Just start the loop at i = 2. Since i = 1 in Number % i it always be equal to zero, since Number is a int.

You can use Decode as well:

SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
      AND A.ITEM_KEY = b.item_key
      AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
                         and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item

• Use a Thread or AsyncTask for long-running operations (50ms+). Test your app to see where that is. Most operations (probably) don't require a thread, because most operations (probably) only involve a few rows. Use a thread for bulk operations.
• Share one SQLiteDatabase instance for each DB on disk between threads and implement a counting system to keep track of open connections.

Are there any best practices for these scenarios?

Share a static field between all your classes. I used to keep a singleton around for that and other things that need to be shared. A counting scheme (generally using AtomicInteger) also should be used to make sure you never close the database early or leave it open.

My solution:

The old version I wrote is available at https://github.com/Taeluf/dev/tree/main/archived/databasemanager and is not maintained. If you want to understand my solution, look at the code and read my notes. My notes are usually pretty helpful.

1. copy/paste the code into a new file named DatabaseManager. (or download it from github)
2. extend DatabaseManager and implement onCreate and onUpgrade like you normally would. You can create multiple subclasses of the one DatabaseManager class in order to have different databases on disk.
3. Instantiate your subclass and call getDb() to use the SQLiteDatabase class.
4. Call close() for each subclass you instantiated

The code to copy/paste:

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;

import java.util.concurrent.ConcurrentHashMap;

This used to require a dedicated API call per key (file), but has been greatly simplified due to the introduction of Amazon S3 - Multi-Object Delete in December 2011:

Amazon S3's new Multi-Object Delete gives you the ability to delete up to 1000 objects from an S3 bucket with a single request.

See my answer to the related question delete from S3 using api php using wildcard for more on this and respective examples in PHP (the AWS SDK for PHP supports this since version 1.4.8).

Most AWS client libraries have meanwhile introduced dedicated support for this functionality one way or another, e.g.:

Python

You can achieve this with the excellent boto Python interface to AWS roughly as follows (untested, from the top of my head):

import boto
s3 = boto.connect_s3()
bucket = s3.get_bucket("bucketname")
bucketListResultSet = bucket.list(prefix="foo/bar")
result = bucket.delete_keys([key.name for key in bucketListResultSet])

Ruby

This is available since version 1.24 of the AWS SDK for Ruby and the release notes provide an example as well:

bucket = AWS::S3.new.buckets['mybucket']

# delete a list of objects by keys, objects are deleted in batches of 1k per
# request.  Accepts strings, AWS::S3::S3Object, AWS::S3::ObectVersion and 
# hashes with :key and :version_id
bucket.objects.delete('key1', 'key2', 'key3', ...)

# delete all of the objects in a bucket (optionally with a common prefix as shown)
bucket.objects.with_prefix('2009/').delete_all

# conditional delete, loads and deletes objects in batches of 1k, only
# deleting those that return true from the block
bucket.objects.delete_if{|object| object.key =~ /\.pdf$/ }

# empty the bucket and then delete the bucket, objects are deleted in batches of 1k
bucket.delete!

Or:

AWS::S3::Bucket.delete('your_bucket', :force => true)

In my case over time I had saved a bunch of versions of myfile as myfile_bak, myfile_old, myfile_2010, backups/myfile etc. I wanted to put myfile's history in git using their modification dates. So rename the oldest to myfile, git add myfile, then git commit --date=(modification date from ls -l) myfile, rename next oldest to myfile, another git commit with --date, repeat...

To automate this somewhat, you can use shell-foo to get the modification time of the file. I started with ls -l and cut, but stat(1) is more direct

git commit --date="`stat -c %y myfile`" myfile

On my Galaxy S4 having > 441dpi > 1080 x 1920 > Getting Actionbar height with getResources().getDimensionPixelSize I got 144 pixels.

Using formula px = dp x (dpi/160), I was using 441dpi, whereas my device lies
in the category 480dpi. so putting that confirms the result.

Here is sample usage using expect:

#!/usr/bin/expect
set timeout 360
spawn my_command # Replace with your command.
expect "Do you want to continue?" { send "\r" }

Check: man expect for further information.

I think what you're trying to do is:

-(void) score2 {
    [self score];
}

The [object message] syntax is the normal way to call a method in objective-c. I think the @selector syntax is used when the method to be called needs to be determined at run-time, but I don't know objective-c well enough to give you more information on that.

awk

awk '{gsub(/two.*/,"")}1' file

Ruby

ruby -ne 'print $_.gsub(/two.*/,"")' file

You get the smallest and quickest loading production bundle by compiling with the Ahead of Time compiler, and tree-shake/minify with rollup as shown in the angular AOT cookbook here: https://angular.io/docs/ts/latest/cookbook/aot-compiler.html

This is also available with the Angular-CLI as said in previous answers, but if you haven't made your app using the CLI you should follow the cookbook.

I also have a working example with materials and SVG charts (backed by Angular2) that it includes a bundle created with the AOT cookbook. You also find all the config and scripts needed to create the bundle. Check it out here: https://github.com/fintechneo/angular2-templates/

I made a quick video demonstrating the difference between number of files and size of an AoT compiled build vs a development environment. It shows the project from the github repository above. You can see it here: https://youtu.be/ZoZDCgQwnmQ

While the other folks who answered this question are (sadly) correct that this information is hidden from us by the browser, I thought I'd post a workaround I came up with:

I configured my server app to set a custom response header (X-Response-Url) containing the url that was requested. Whenever my ajax code receives a response, it checks if xhr.getResponseHeader("x-response-url") is defined, in which case it compares it to the url that it originally requested via $.ajax(). If the strings differ, I know there was a redirect, and additionally, what url we actually arrived at.

This does have the drawback of requiring some server-side help, and also may break down if the url gets munged (due to quoting/encoding issues etc) during the round trip... but for 99% of cases, this seems to get the job done.

On the server side, my specific case was a python application using the Pyramid web framework, and I used the following snippet:

import pyramid.events

@pyramid.events.subscriber(pyramid.events.NewResponse)
def set_response_header(event):
    request = event.request
    if request.is_xhr:
        event.response.headers['X-Response-URL'] = request.url

java.time

It’s about time someone provides the modern answer. The modern solution uses java.time, the modern Java date and time API. The classes SimpleDateFormat and Date used in the question and in a couple of the other answers are poorly designed and long outdated, the former in particular notoriously troublesome. TimeZone is poorly designed to. I recommend you avoid those.

    ZoneId utc = ZoneId.of("Etc/UTC");
    DateTimeFormatter targetFormatter = DateTimeFormatter.ofPattern(
            "MM/dd/yyyy hh:mm:ss a zzz", Locale.ENGLISH);

    String itsAlarmDttm = "2013-10-22T01:37:56";
    ZonedDateTime utcDateTime = LocalDateTime.parse(itsAlarmDttm)
            .atZone(ZoneId.systemDefault())
            .withZoneSameInstant(utc);
    String formatterUtcDateTime = utcDateTime.format(targetFormatter);
    System.out.println(formatterUtcDateTime);

When running in my time zone, Europe/Copenhagen, the output is:

10/21/2013 11:37:56 PM UTC

I have assumed that the string you got was in the default time zone of your JVM, a fragile assumption since that default setting can be changed at any time from another part of your program or another programming running in the same JVM. If you can, instead specify time zone explicitly, for example ZoneId.of("Europe/Podgorica") or ZoneId.of("Asia/Kolkata").

I am exploiting the fact that you string is in ISO 8601 format, the format the the modern classes parse as their default, that is, without any explicit formatter.

I am using a ZonedDateTime for the result date-time because it allows us to format it with UTC in the formatted string to eliminate any and all doubt. For other purposes one would typically have wanted an OffsetDateTime or an Instant instead.

EDIT: updated the snippets for a more generic approach

Just as an extension to the accepted answer,

For getting the existing styles to preserve the look 'n feel of the targeted component, you can:

1. make a query to pull the <style> and <link> elements from the top-level document

2. inject it into the HTML string.

To grab a HTML tag:

private getTagsHtml(tagName: keyof HTMLElementTagNameMap): string
{
    const htmlStr: string[] = [];
    const elements = document.getElementsByTagName(tagName);
    for (let idx = 0; idx < elements.length; idx++)
    {
        htmlStr.push(elements[idx].outerHTML);
    }

    return htmlStr.join('\r\n');
}

Then in the existing snippet:

const printContents = document.getElementById('print-section').innerHTML;
const stylesHtml = this.getTagsHtml('style');
const linksHtml = this.getTagsHtml('link');

const popupWin = window.open('', '_blank', 'top=0,left=0,height=100%,width=auto');
popupWin.document.open();
popupWin.document.write(`
    <html>
        <head>
            <title>Print tab</title>
            ${linksHtml}
            ${stylesHtml}
            ^^^^^^^^^^^^^ add them as usual to the head
        </head>
        <body onload="window.print(); window.close()">
            ${printContents}
        </body>
    </html>
    `
);
popupWin.document.close();

Now using existing styles (Angular components create a minted style for itself), as well as existing style frameworks (e.g. Bootstrap, MaterialDesign, Bulma) it should look like a snippet of the existing screen

Had the same error with PHP 7 on XAMPP and OSX.

The above mentioned answer in https://stackoverflow.com/ is good, but it did not completely solve the problem for me. I had to provide the complete certificate chain to make file_get_contents() work again. That's how I did it:

Get root / intermediate certificate

First of all I had to figure out what's the root and the intermediate certificate.

The most convenient way is maybe an online cert-tool like the ssl-shopper

There I found three certificates, one server-certificate and two chain-certificates (one is the root, the other one apparantly the intermediate).

All I need to do is just search the internet for both of them. In my case, this is the root:

thawte DV SSL SHA256 CA

And it leads to his url thawte.com. So I just put this cert into a textfile and did the same for the intermediate. Done.

Get the host certificate

Next thing I had to to is to download my server cert. On Linux or OS X it can be done with openssl:

openssl s_client -showcerts -connect whatsyoururl.de:443 </dev/null 2>/dev/null|openssl x509 -outform PEM > /tmp/whatsyoururl.de.cert

Now bring them all together

Now just merge all of them into one file. (Maybe it's good to just put them into one folder, I just merged them into one file). You can do it like this:

cat /tmp/thawteRoot.crt > /tmp/chain.crt
cat /tmp/thawteIntermediate.crt >> /tmp/chain.crt
cat /tmp/tmp/whatsyoururl.de.cert >> /tmp/chain.crt

tell PHP where to find the chain

There is this handy function openssl_get_cert_locations() that'll tell you, where PHP is looking for cert files. And there is this parameter, that will tell file_get_contents() where to look for cert files. Maybe both ways will work. I preferred the parameter way. (Compared to the solution mentioned above).

So this is now my PHP-Code

$arrContextOptions=array(
    "ssl"=>array(
        "cafile" => "/Applications/XAMPP/xamppfiles/share/openssl/certs/chain.pem",
        "verify_peer"=> true,
        "verify_peer_name"=> true,
    ),
);

$response = file_get_contents($myHttpsURL, 0, stream_context_create($arrContextOptions));

That's all. file_get_contents() is working again. Without CURL and hopefully without security flaws.

I highly recommend you to use ViewStubs like this

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <ViewStub
        android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout="@layout/empty" />
</FrameLayout>

If you are looking for ad-hoc items rather than something that you would put into SSIS. From within SSMS simply highlight the results grid, copy, then paste into excel, it isn't elegant, but works. Then you can save as native .xls rather than .csv

VS 17 Community Edition is free. You just need to sign-in with your Microsoft account and everything will be fine again.

I ran into a similar error, but refering to Spring Webflow in a newly created Roo project. The solution for me turned out to be (Project) / right-click / Maven / Enable Maven Dependencies (followed by some restarts and republishes to Tomcat).

It appeared that STS or m2Eclipse was failing to push all the spring webflow jars into the web app lib directory. I'm not sure why. But enabling maven dependency handling and then rebuilding seemed to fix the problem; the webflow jars finally get published and thus it can find the schema namespace references.

I investigated this by exploring the tomcat directory that the web app was published to, clicking into WEB-INF/lib/ while it was running and noticing that it was missing webflow jar files.

In my case, I use

$.getJSON(url, function(json) { ... });

to make the request (to Flickr's API), and I got the same MIME error. Like the answer above suggested, adding the following code:

$.ajaxSetup({ dataType: "jsonp" });

Fixed the issue and I no longer see the MIME type error in Chrome's console.

In your statement, you are comparing a string called start_date with the time.
If start_date is a column, it should either be

 
  SELECT * FROM `la_schedule` WHERE start_date >'2012-11-18';
 

(no apostrophe) or

SELECT * FROM `la_schedule` WHERE `start_date` >'2012-11-18';

(with backticks).

Hope this helps.

    } else {_x000D_

The rules for parsing colors on legacy attributes involves additional steps than those mentioned in existing answers. The truncate component to 2 digits part is described as:

1. Discard all characters except the last 8
2. Discard leading zeros one by one as long as all components have a leading zero
3. Discard all characters except the first 2

Some examples:

oooFoooFoooF
000F 000F 000F                <- replace, pad and chunk
0F 0F 0F                      <- leading zeros truncated
0F 0F 0F                      <- truncated to 2 characters from right

oooFooFFoFFF
000F 00FF 0FFF                <- replace, pad and chunk
00F 0FF FFF                   <- leading zeros truncated
00 0F FF                      <- truncated to 2 characters from right

Another solution is to migrate the database to e.g 2012 when you "export" the DB from e.g. Sql Server manager 2014. This is done in menu Tasks-> generate scripts when right-click on DB. Just follow this instruction:

https://www.mssqltips.com/sqlservertip/2810/how-to-migrate-a-sql-server-database-to-a-lower-version/

It generates an scripts with everything and then in your SQL server manager e.g. 2012 run the script as specified in the instruction. I have performed the test with success.

Keeping it simple, I personally like string concatenation:

print("Total score for " + name + " is " + score)

It works with both Python 2.7 an 3.X.

NOTE: If score is an int, then, you should convert it to str:

print("Total score for " + name + " is " + str(score))

You can also execute the following code. It is tested and working.

If you have a maven artifact with 2 snapshots

name => 'com.acme.derp'
version => 0.1.0
repo name => 'foo'

and

undefined index means that somewhere in the $_POST array, there isn't an index (key) for the key username.

You should be setting your posted values into variables for a more clean solution, and it's a good habit to get into.

If I was having a similar error, I'd do something like this:

$username = $_POST['username']; // you should really do some more logic to see if it's set first
echo $username;

If username didn't turn up, that'd mean I was screwing up somewhere. You can also,

var_dump($_POST);

To see what you're posting. var_dump is really useful as far as debugging. Check it out: var_dump

December 2020 :

• We have now Firefox 83.0 and Chrome 87.0
• Internet Explorer is dead, it has been replaced by the new Chromium-based Edge 87.0
• Silverlight is dead
• Windows XP is dead
• WMV is not a standard : https://www.w3schools.com/html/html_media.asp

To answer the question :

• You have to convert your WMV file to another format : MP4, WebM or Ogg video.
• Then embed it in your page with the HTML 5 <video> element.

I think this question should be closed.

Different types of variable:

• local variables (which are not prefixed by @) are strongly typed and scoped to the stored program block in which they are declared. Note that, as documented under DECLARE Syntax:

DECLARE is permitted only inside a BEGIN ... END compound statement and must be at its start, before any other statements.

• User variables (which are prefixed by @) are loosely typed and scoped to the session. Note that they neither need nor can be declared—just use them directly.

Therefore, if you are defining a stored program and actually do want a "local variable", you will need to drop the @ character and ensure that your DECLARE statement is at the start of your program block. Otherwise, to use a "user variable", drop the DECLARE statement.

Furthermore, you will either need to surround your query in parentheses in order to execute it as a subquery:

SET @countTotal = (SELECT COUNT(*) FROM nGrams);

Or else, you could use SELECT ... INTO:

SELECT COUNT(*) INTO @countTotal FROM nGrams;

It's part of Xcode. You'll need to reinstall the developer tools.

Without using reversed or [::-1], here is a simple version based on recursion i would consider to be the most readable:

def reverse(s):

  if len(s)==2:
    return s[-1] + s[0]

  if len(s)==1:
    return s[0]

  return s[-1] + reverse(s[1:len(s)-1]) + s[0]

Here you go, no frameworks, short and simple:

var el = document.getElementById('elId');
var elTop = el.getBoundingClientRect().top - document.body.getBoundingClientRect().top;

window.addEventListener('scroll', function(){
    if (document.documentElement.scrollTop > elTop){
        el.style.position = 'fixed';
        el.style.top = '0px';
    }
    else
    {
        el.style.position = 'static';
        el.style.top = 'auto';
    }
});

Deprecated answer (Spring Data JPA <=1.6.x):

@Modifying annotation to the rescue. You will need to provide your custom SQL behaviour though.

public interface UserRepository extends JpaRepository<User, Long> {
    @Modifying
    @Query("delete from User u where u.firstName = ?1")
    void deleteUsersByFirstName(String firstName);
}

Update:

In modern versions of Spring Data JPA (>=1.7.x) query derivation for delete, remove and count operations is accessible.

public interface UserRepository extends CrudRepository<User, Long> {

    Long countByFirstName(String firstName);

    Long deleteByFirstName(String firstName);

    List<User> removeByFirstName(String firstName);

}

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");

$('.select_continent').click(function () {
    alert($(this).attr('value'));
});

You can use a single group for seconds/minutes. The following expression may suit your needs:

([0-9]+)\s*(seconds|minutes)

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

In windows 10 you can find it here:

C:\Users\[USER]\AppData\Local\conda\conda\envs\[ENVIRONMENT]\python.exe

you can follow the below command to install using the wheel file at your local

pip install /users/arpansaini/Downloads/h5py-3.0.0-cp39-cp39-macosx_10_9_x86_64.whl

String s1="foo";

literal will go in pool and s1 will refer.

String s2="foo";

this time it will check "foo" literal is already available in StringPool or not as now it exist so s2 will refer the same literal.

String s3=new String("foo");

"foo" literal will be created in StringPool first then through string arg constructor String Object will be created i.e "foo" in the heap due to object creation through new operator then s3 will refer it.

String s4=new String("foo");

same as s3

so System.out.println(s1==s2);// **true** due to literal comparison.

and System.out.println(s3==s4);// **false** due to object

comparison(s3 and s4 is created at different places in heap)

I have tried this and it is working fine for me:

You may want to declare the button content outside of the dialog, this works for me.

var closeFunction = function() {
    $(#dialog).dialog( "close" );
};

$('#dialog').dialog({
    modal: true,
    buttons: {
        Ok: closeFunction
    }
});

Checkboxes, by design, are meant to be toggled on or off. They are not dependent on other checkboxes, so you can turn as many on and off as you wish.

Radio buttons, however, are designed to only allow one element of a group to be selected at any time.

Yes,that is called short-circuiting.

Please take a look at this wikipedia page on short-circuiting

Reflection gives you the ability to write more generic code. It allows you to create an object at runtime and call its method at runtime. Hence the program can be made highly parameterized. It also allows introspecting the object and class to detect its variables and method exposed to the outer world.

There are several ways to cut a line, all controlled by the d key in normal mode. If you are using visual mode (the v key) you can just hit the d key once you have highlighted the region you want to cut. Move to the location you would like to paste and hit the p key to paste.

It's also worth mentioning that you can copy/cut/paste from registers. Suppose you aren't sure when or where you want to paste the text. You could save the text to up to 24 registers identified by an alphabetical letter. Just prepend your command with ' (single quote) and the register letter (a thru z). For instance you could use the visual mode (v key) to select some text and then type 'ad to cut the text and store it in register 'a'. Once you navigate to the location where you want to paste the text you would type 'ap to paste the contents of register a.

I tried many different ways and this way is the only one worked for me

//check all images on the page
$('img').each(function(){
    var img = new Image();
    img.onload = function() {
        console.log($(this).attr('src') + ' - done!');
    }
    img.src = $(this).attr('src');
});

You could also add a callback function triggered once all images are loaded in the DOM and ready. This applies for dynamically added images too. http://jsfiddle.net/kalmarsh80/nrAPk/

If the numbers are seprated by whitespace in the string then you can use sscanf(). Since, it's not the case with your example, you have to do it yourself:

char tmp[256];

for(i=0;str[i];i++)
{
  j=0;
  while(str[i]>='0' && str[i]<='9')
  {
     tmp[j]=str[i];
     i++;
     j++;
  }
  tmp[j]=0;
  printf("%ld", strtol(tmp, &tmp, 10));
  // Or store in an integer array

}

They are the same thing. .hide() calls a jQuery function and allows you to add a callback function to it. So, with .hide() you can add an animation for instance.

.css("display","none") changes the attribute of the element to display:none. It is the same as if you do the following in JavaScript:

document.getElementById('elementId').style.display = 'none';

The .hide() function obviously takes more time to run as it checks for callback functions, speed, etc...

Angular syntax is to use the : operator to perform the equivalent of an if modifier

<div ng-class="{ 'clearfix' : (row % 2) == 0 }">

Add clearfix class to even rows. Nonetheless, expression could be anything we can have in normal if condition and it should evaluate to either true or false.

That is not possible with a normal query since the in clause needs separate values and not a single value containing a comma separated list. One solution would be a dynamic query

declare @myList varchar(100)
set @myList = '(1,2,5,7,10)'
exec('select * from DBTable where id IN ' + @myList)

For infinite Fade In and Out

AlphaAnimation fadeIn=new AlphaAnimation(0,1);

AlphaAnimation fadeOut=new AlphaAnimation(1,0);


final AnimationSet set = new AnimationSet(false);

set.addAnimation(fadeIn);
set.addAnimation(fadeOut);
fadeOut.setStartOffset(2000);
set.setDuration(2000);
imageView.startAnimation(set);

set.setAnimationListener(new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) { }
    @Override
    public void onAnimationRepeat(Animation animation) { }
    @Override
    public void onAnimationEnd(Animation animation) {
        imageView.startAnimation(set);
    }
});

Well, you should think about one more thing.

If you have a really big dataset, like 1,000,000 examples, split 80/10/10 may be unnecessary, because 10% = 100,000 examples may be just too much for just saying that model works fine.

Maybe 99/0.5/0.5 is enough because 5,000 examples can represent most of the variance in your data and you can easily tell that model works good based on these 5,000 examples in test and dev.

Don't use 80/20 just because you've heard it's ok. Think about the purpose of the test set.

If you've got many database it import and the dumps is big (I often work with multigigabyte Gzipped dumps).

There here a way to do it inside mysql.

$ mkdir databases
$ cd databases
$ scp user@orgin:*.sql.gz .  # Here you would just use putty to copy into this dir.
$ mkfifo src
$ mysql -u root -p
Enter password:

.

The only advantage this has over

zcat db1.sql.gz | mysql -u root -p 

is that you can easily do multiple without enter the password lots of times.

At this time, I would answer "no" or "with difficulty", but that could change over time as the android NFC API evolves.

There are three modes of NFC interaction:

1. Reader-Writer: The phone reads tags and writes to them. It's not emulating a card instead an NFC reader/writer device. Hence, you can't emulate a tag in this mode.

2. Peer-to-peer: the phone can read and pass back ndef messages. If the tag reader supports peer-to-peer mode, then the phone could possibly act as a tag. However, I'm not sure if android uses its own protocol on top of the LLCP protocol (NFC logical link protocol), which would then prevent most readers from treating the phone as an nfc tag.

3. Card-emulation mode: the phone uses a secure element to emulate a smart card or other contactless device. I am not sure if this is launched yet, but could provide promising. However, using the secure element might require the hardware vendor or some other person to verify your app / give it permissions to access the secure element. It's not as simple as creating a regular NFC android app.

More details here: http://www.mail-archive.com/[email protected]/msg152222.html

A real question would be: why are you trying to emulate a simple old nfc tag? Is there some application I'm not thinking of? Usually, you'd want to emulate something like a transit card, access key, or credit card which would require a secure element (I think, but not sure).

Just add another way , in normal mode , type ctrl+v then G, select the rest, then D, I don't think it is effective , you should do like @Ed Guiness, head -n 20 > filename in linux.

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

The toString method of array types in Java isn't particularly meaningful, other than telling you what that is an array of.

You can use java.util.Arrays.toString for that.

Or if your lines only contain numbers, and you want a line as 1,2,3,4... instead of [1, 2, 3, ...], you can use:

java.util.Arrays.toString(someArray).replaceAll("\\]| |\\[","")

In the case of a past rebase that you did not properly aborted, you now (Git 2.12, Q1 2017) have git rebase --quit

See commit 9512177 (12 Nov 2016) by Nguy?n Thái Ng?c Duy (pclouds). ^{(Merged by Junio C Hamano -- gitster -- in commit 06cd5a1, 19 Dec 2016)}

rebase: add --quit to cleanup rebase, leave everything else untouched

There are occasions when you decide to abort an in-progress rebase and move on to do something else but you forget to do "git rebase --abort" first. Or the rebase has been in progress for so long you forgot about it. By the time you realize that (e.g. by starting another rebase) it's already too late to retrace your steps. The solution is normally

rm -r .git/<some rebase dir>

and continue with your life.
But there could be two different directories for <some rebase dir> (and it obviously requires some knowledge of how rebase works), and the ".git" part could be much longer if you are not at top-dir, or in a linked worktree. And "rm -r" is very dangerous to do in .git, a mistake in there could destroy object database or other important data.

Provide "git rebase --quit" for this use case, mimicking a precedent that is "git cherry-pick --quit".

Before Git 2.27 (Q2 2020), The stash entry created by "git merge --autostash" to keep the initial dirty state were discarded by mistake upon "git rebase --quit", which has been corrected.

See commit 9b2df3e (28 Apr 2020) by Denton Liu (Denton-L).
^{(Merged by Junio C Hamano -- gitster -- in commit 3afdeef, 29 Apr 2020)}

rebase: save autostash entry into stash reflog on --quit

^{Signed-off-by: Denton Liu}

In a03b55530a ("merge: teach --autostash option", 2020-04-07, Git v2.27.0 -- merge listed in batch #5), the --autostash option was introduced for git merge.

(See "Can “git pull” automatically stash and pop pending changes?")

Notably, when git merge --quit is run with an autostash entry present, it is saved into the stash reflog.

This is contrasted with the current behaviour of git rebase --quit where the autostash entry is simply just dropped out of existence.

Adopt the behaviour of git merge --quit in git rebase --quit and save the autostash entry into the stash reflog instead of just deleting it.

I tried working with the string form rather than the number and this seemed to work. I have only tested this on Chrome but it should be universal:

function removeExponent(s) {
    var ie = s.indexOf('e');
    if (ie != -1) {
        if (s.charAt(ie + 1) == '-') {
            // negative exponent, prepend with .0s
            var n = s.substr(ie + 2).match(/[0-9]+/);
            s = s.substr(2, ie - 2); // remove the leading '0.' and exponent chars
            for (var i = 0; i < n; i++) {
                s = '0' + s;
            }
            s = '.' + s;
        } else {
            // positive exponent, postpend with 0s
            var n = s.substr(ie + 1).match(/[0-9]+/);
            s = s.substr(0, ie); // strip off exponent chars            
            for (var i = 0; i < n; i++) {
                s += '0';
            }       
        }
    }
    return s;
}

You can view your certificate or any other website's by changing the site name in this link

Please do not forget that it is only valid for 90 days

When your certificate expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. There is no ‘Renew’ button that allows you to renew your certificate. You can revoke a certificate and generate a new one before it expires. Or you can wait for it to expire and disappear, then generate a new certificate. In Apple's App Distribution Guide:

Replacing Expired Certificates

When your development or distribution certificate expires, remove it and request a new certificate in Xcode.

When your certificate expires or is revoked, any provisioning profile that made use of the expired/revoked certificate will be reflected as ‘Invalid’. You cannot build and sign any app using these invalid provisioning profiles. As you can imagine, I'd rather revoke and regenerate a certificate before it expires.

Q: If I do that then will all my live apps be taken down?

Apps that are already on the App Store continue to function fine. Again, in Apple's App Distribution Guide:

Important: Re-creating your development or distribution certificates doesn’t affect apps that you’ve submitted to the store nor does it affect your ability to update them.

So…

Q: How to I properly renew it?

As mentioned above, there is no renewing of certificates. Follow the steps below to revoke and regenerate a new certificate, along with the affected provisioning profiles. The instructions have been updated for Xcode 8.3 and Xcode 9.

Step 1: Revoke the expiring certificate

Login to Member Center > Certificates, Identifiers & Profiles, select the expiring certificate. Take note of the expiry date of the certificate, and click the ‘Revoke’ button.

Step 2: (Optional) Remove the revoked certificate from your Keychain

Optionally, if you don't want to have the revoked certificate lying around in your system, you can delete them from your system. Unfortunately, the ‘Delete Certificate’ function in Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates… seems to be always disabled, so we have to delete them manually using Keychain Access.app (/Applications/Utilities/Keychain Access.app).

Filter by ‘login’ Keychains and ‘Certificates’ Category. Locate the certificate that you've just revoked in Step 1.

Depending on the certificate that you've just revoked, search for either ‘Mac’ or ‘iPhone’. Mac App Store distribution certificates begin with “3rd Party Mac Developer”, and iOS App Store distribution certificates begin with “iPhone Distribution”.

You can locate the revoked certificate based on the team name, the type of certificate (Mac or iOS) and the expiry date of the certificate you've noted down in Step 1.

Step 3: Request a new certificate using Xcode

Under Xcode > Preferences > Accounts > [Apple ID] > Manage Certificates…, click on the ‘+’ button on the lower left, and select the same type of certificate that you've just revoked to let Xcode request a new one for you.

Step 4: Update your provisioning profiles to use the new certificate

After which, head back to Member Center > Certificates, Identifiers & Profiles > Provisioning Profiles > All. You'll notice that any provisioning profile that made use of the revoked certificate is now reflected as ‘Invalid’.

Click on any profile that are now ‘Invalid’, click ‘Edit’, then choose the newly created certificate, then click on ‘Generate’. Repeat this until all provisioning profiles are regenerated with the new certificate.

Step 5: Use Xcode to download the new provisioning profiles

Tip: Before you download the new profiles using Xcode, you may want to clear any existing and possibly invalid provisioning profiles from your Mac. You can do so by removing all the profiles from ~/Library/MobileDevice/Provisioning Profiles

Back in Xcode > Preferences > Accounts > [Apple ID], click on the ‘Download All Profiles’ button to ask Xcode to download all the provisioning profiles from your developer account.

As @letitbee said, its best practice to assign primary keys to tables and properly define the relationships to allow for proper ORM querying. That being said...

If you're interested in writing a query along the lines of:

SELECT
    user.email,
    user.name,
    document.name,
    documents_permissions.readAllowed,
    documents_permissions.writeAllowed
FROM
    user, document, documents_permissions
WHERE
    user.email = "[email protected]";

Then you should go for something like:

session.query(
    User, 
    Document, 
    DocumentsPermissions
).filter(
    User.email == Document.author
).filter(
    Document.name == DocumentsPermissions.document
).filter(
    User.email == "[email protected]"
).all()

If instead, you want to do something like:

SELECT 'all the columns'
FROM user
JOIN document ON document.author_id = user.id AND document.author == User.email
JOIN document_permissions ON document_permissions.document_id = document.id AND document_permissions.document = document.name

Then you should do something along the lines of:

session.query(
    User
).join(
    Document
).join(
    DocumentsPermissions
).filter(
    User.email == "[email protected]"
).all()

One note about that...

query.join(Address, User.id==Address.user_id) # explicit condition
query.join(User.addresses)                    # specify relationship from left to right
query.join(Address, User.addresses)           # same, with explicit target
query.join('addresses')                       # same, using a string

Update (using renderer):

Note that the original Renderer service has now been deprecated in favor of Renderer2

as on Renderer2 official doc.

Furthermore, as pointed out by @GünterZöchbauer:

Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.

You can achieve this by using elementRef as well as by ViewChild. however it's not recommendable to use elementRef due to:

• security issue
• tight coupling

as pointed out by official ng2 documentation.

1. Using elementRef (Direct Access):

export class MyComponent {    
constructor (private _elementRef : ElementRef) {
 this._elementRef.nativeElement.querySelector('textarea').focus();
 }
}

2. Using ViewChild (better approach):

<textarea  #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}" 
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var


export class MyComponent implements AfterViewInit {
  @ViewChild('tasknote') input: ElementRef;

   ngAfterViewInit() {
    this.input.nativeElement.focus();

  }
}

3. Using renderer:

export class MyComponent implements AfterViewInit {
      @ViewChild('tasknote') input: ElementRef;
         constructor(private renderer: Renderer2){           
          }

       ngAfterViewInit() {
       //using selectRootElement instead of depreaced invokeElementMethod
       this.renderer.selectRootElement(this.input["nativeElement"]).focus();
      }

    }

The short answer, or TL;DR

Basically, eval is used to evaluate a single dynamically generated Python expression, and exec is used to execute dynamically generated Python code only for its side effects.

eval and exec have these two differences:

1. eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.

   An expression in Python is whatever you can have as the value in a variable assignment:

   a_variable = (anything you can put within these parentheses is an expression)
   

2. eval returns the value of the given expression, whereas exec ignores the return value from its code, and always returns None (in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).

In versions 1.0 - 2.7, exec was a statement, because CPython needed to produce a different kind of code object for functions that used exec for its side effects inside the function.

In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used.

Thus basically:

>>> a = 5
>>> eval('37 + a')   # it is an expression
42
>>> exec('37 + a')   # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47')   # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47')  # you cannot evaluate a statement
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    a = 47
      ^
SyntaxError: invalid syntax

The compile in 'exec' mode compiles any number of statements into a bytecode that implicitly always returns None, whereas in 'eval' mode it compiles a single expression into bytecode that returns the value of that expression.

>>> eval(compile('42', '<string>', 'exec'))  # code returns None
>>> eval(compile('42', '<string>', 'eval'))  # code returns 42
42
>>> exec(compile('42', '<string>', 'eval'))  # code returns 42,
>>>                                          # but ignored by exec

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval') This is where the difference really comes from.

If a code object (which contains Python bytecode) is passed to exec or eval, they behave identically, excepting for the fact that exec ignores the return value, still returning None always. So it is possible use eval to execute something that has statements, if you just compiled it into bytecode before instead of passing it as a string:

>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>

works without problems, even though the compiled code contains statements. It still returns None, because that is the return value of the code object returned from compile.

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

The longer answer, a.k.a the gory details

exec and eval

The exec function (which was a statement in Python 2) is used for executing a dynamically created statement or program:

>>> program = '''
for i in range(3):
    print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>> 

The eval function does the same for a single expression, and returns the value of the expression:

>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84

exec and eval both accept the program/expression to be run either as a str, unicode or bytes object containing source code, or as a code object which contains Python bytecode.

If a str/unicode/bytes containing source code was passed to exec, it behaves equivalently to:

exec(compile(source, '<string>', 'exec'))

and eval similarly behaves equivalent to:

eval(compile(source, '<string>', 'eval'))

Since all expressions can be used as statements in Python (these are called the Expr nodes in the Python abstract grammar; the opposite is not true), you can always use exec if you do not need the return value. That is to say, you can use either eval('my_func(42)') or exec('my_func(42)'), the difference being that eval returns the value returned by my_func, and exec discards it:

>>> def my_func(arg):
...     print("Called with %d" % arg)
...     return arg * 2
... 
>>> exec('my_func(42)')
Called with 42
>>> eval('my_func(42)')
Called with 42
84
>>> 

Of the 2, only exec accepts source code that contains statements, like def, for, while, import, or class, the assignment statement (a.k.a a = 42), or entire programs:

>>> exec('for i in range(3): print(i)')
0
1
2
>>> eval('for i in range(3): print(i)')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Both exec and eval accept 2 additional positional arguments - globals and locals - which are the global and local variable scopes that the code sees. These default to the globals() and locals() within the scope that called exec or eval, but any dictionary can be used for globals and any mapping for locals (including dict of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the executed code creates:

>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}

(If you display the value of the entire g, it would be much longer, because exec and eval add the built-ins module as __builtins__ to the globals automatically if it is missing).

In Python 2, the official syntax for the exec statement is actually exec code in globals, locals, as in

>>> exec 'global a; a, b = 123, 42' in g, l

However the alternate syntax exec(code, globals, locals) has always been accepted too (see below).

compile

The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1) built-in can be used to speed up repeated invocations of the same code with exec or eval by compiling the source into a code object beforehand. The mode parameter controls the kind of code fragment the compile function accepts and the kind of bytecode it produces. The choices are 'eval', 'exec' and 'single':

• 'eval' mode expects a single expression, and will produce bytecode that when run will return the value of that expression:

  >>> dis.dis(compile('a + b', '<string>', 'eval'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 RETURN_VALUE
  

• 'exec' accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None:

  >>> dis.dis(compile('a + b', '<string>', 'exec'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 POP_TOP                             <- discard result
                8 LOAD_CONST               0 (None)   <- load None on stack
               11 RETURN_VALUE                        <- return top of stack
  

• 'single' is a limited form of 'exec' which accepts a source code containing a single statement (or multiple statements separated by ;) if the last statement is an expression statement, the resulting bytecode also prints the repr of the value of that expression to the standard output(!).

  An if-elif-else chain, a loop with else, and try with its except, else and finally blocks is considered a single statement.

  A source fragment containing 2 top-level statements is an error for the 'single', except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:

  In Python 2.7.8:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  >>> a
  5
  

  And in Python 3.4.2:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 1
      a = 5
          ^
  SyntaxError: multiple statements found while compiling a single statement
  

  This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval the resulting code.

Thus greatest distinction of exec and eval actually comes from the compile function and its modes.

In addition to compiling source code to bytecode, compile supports compiling abstract syntax trees (parse trees of Python code) into code objects; and source code into abstract syntax trees (the ast.parse is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.

While eval only allows you to evaluate a string that contains a single expression, you can eval a whole statement, or even a whole module that has been compiled into bytecode; that is, with Python 2, print is a statement, and cannot be evalled directly:

>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print("Python is cool")
      ^
SyntaxError: invalid syntax

compile it with 'exec' mode into a code object and you can eval it; the eval function will return None.

>>> code = compile('for i in range(3): print("Python is cool")',
                   'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool

If one looks into eval and exec source code in CPython 3, this is very evident; they both call PyEval_EvalCode with same arguments, the only difference being that exec explicitly returns None.

Syntax differences of exec between Python 2 and Python 3

One of the major differences in Python 2 is that exec is a statement and eval is a built-in function (both are built-in functions in Python 3). It is a well-known fact that the official syntax of exec in Python 2 is exec code [in globals[, locals]].

Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec statement in CPython 2 can be also used with syntax that looks exactly like the exec function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals) built-in function! And that built-in function was replaced with exec statement somewhere before Python 1.0 release.

Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code was a tuple of length 2 or 3, and globals and locals were not passed into the exec statement otherwise, the code would be interpreted as if the 2nd and 3rd element of the tuple were the globals and locals respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:

The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals. The tuple form of exec provides compatibility with Python 3, where exec is a function rather than a statement.

Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.

Thus while exec is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,

>>> exec("print(a)", globals(), {'a': 42})
42

has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).

What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec into a variable:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
  File "<stdin>", line 1
    a = exec('print(42)')
           ^
SyntaxError: invalid syntax

(which wouldn't be useful in Python 3 either, as exec always returns None), or pass a reference to exec:

>>> call_later(exec, 'print(42)', delay=1000)
  File "<stdin>", line 1
    call_later(exec, 'print(42)', delay=1000)
                  ^
SyntaxError: invalid syntax

Which a pattern that someone might actually have used, though unlikely;

Or use it in a list comprehension:

>>> [exec(i) for i in ['print(42)', 'print(foo)']
  File "<stdin>", line 1
    [exec(i) for i in ['print(42)', 'print(foo)']
        ^
SyntaxError: invalid syntax

which is abuse of list comprehensions (use a for loop instead!).

It has ability to convert HTML file in to pdf.

Required namespace for conversions are:

using iTextSharp.text;
using iTextSharp.text.pdf;

and for conversion and download file :

// Create a byte array that will eventually hold our final PDF
Byte[] bytes;

// Boilerplate iTextSharp setup here

// Create a stream that we can write to, in this case a MemoryStream
using (var ms = new MemoryStream())
{
    // Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF
    using (var doc = new Document())
    {
        // Create a writer that's bound to our PDF abstraction and our stream
        using (var writer = PdfWriter.GetInstance(doc, ms))
        {
            // Open the document for writing
            doc.Open();

            string finalHtml = string.Empty;

            // Read your html by database or file here and store it into finalHtml e.g. a string
            // XMLWorker also reads from a TextReader and not directly from a string
            using (var srHtml = new StringReader(finalHtml))
            {
                // Parse the HTML
                iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
            }

            doc.Close();
        }
    }

    // After all of the PDF "stuff" above is done and closed but **before** we
    // close the MemoryStream, grab all of the active bytes from the stream
    bytes = ms.ToArray();
}

// Clear the response
Response.Clear();
MemoryStream mstream = new MemoryStream(bytes);

// Define response content type
Response.ContentType = "application/pdf";

// Give the name of file of pdf and add in to header
Response.AddHeader("content-disposition", "attachment;filename=invoice.pdf");
Response.Buffer = true;
mstream.WriteTo(Response.OutputStream);
Response.End();

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

You can try this in Swift 5.2:

func playSound() {
        let soundURL = Bundle.main.url(forResource: selectedSoundFileName, withExtension: "wav")
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: soundURL!)
        }
        catch {
            print(error)
        }
        audioPlayer.play()
    }

babel module in python has feature to apply commas depending on the locale provided.

To install babel run the below command.

pip install babel

usage

format_currency(1234567.89, 'USD', locale='en_US')
# Output: $1,234,567.89
format_currency(1234567.89, 'USD', locale='es_CO')
# Output: US$ 1.234.567,89 (raw output US$\xa01.234.567,89)
format_currency(1234567.89, 'INR', locale='en_IN')
# Output: ?12,34,567.89

Although I've used the accepted answer in the past, it seems with the current Build Tools it is possible to do:

   <dimen name="listAvatarWidthPercent">0.19</dimen>

I'm using Build Tools major version 29.

DistCp (distributed copy) is a tool used for copying data between clusters. It uses MapReduce to effect its distribution, error handling and recovery, and reporting. It expands a list of files and directories into input to map tasks, each of which will copy a partition of the files specified in the source list.

Usage: $ hadoop distcp <src> <dst>

example: $ hadoop distcp hdfs://nn1:8020/file1 hdfs://nn2:8020/file2

file1 from nn1 is copied to nn2 with filename file2

Distcp is the best tool as of now. Sqoop is used to copy data from relational database to HDFS and vice versa, but not between HDFS to HDFS.

More info:

• http://hadoop.apache.org/docs/r1.2.1/distcp.html
• http://hadoop.apache.org/docs/r1.2.1/distcp2.html

There are two versions available - runtime performance in distcp2 is more compared to distcp

I think that Andrei Coscodan answer is the best when you can't make many assumptions. But sometimes having a one-liner is nice if you can make some some assumptions. This solution assumes that 'date \t' will return one of two formats. On WindowsXP 'date /t 'returns "11/23/2011", but on Windows7 it returns "Wed 11/23/2011".

FOR /f "tokens=1-4 delims=/ " %%a in ('date /t') do (set mm=%%a&set dd=%%b&set yyyy=%%c& (if "%%a:~0,1" gtr "9" set mm=%%b&setdd=%%c&set yyyy=%%d))
:: Test results
echo day in 'DD' format is '%dd%'; month in 'MM' format is '%mm%'; year in 'YYYY' format is '%yyyy%'

Thanks to Andrei Consodan answer to help me with this one-line solution.

I faced the same issue and I solved it by removing a jar which was added twice in two different dependencies on my pom.xml. Removing one of the dependency solved the issue.

With Termsql you can do it in one line:

termsql -i mycsvfile.CSV -d ',' -c 'a,b' -t 'foo' -o mynewdatabase.db

1. A ViewGroup is a special view that can contain other views (called children.) The view group is the base class for layouts and views containers. This class also defines the ViewGroup.LayoutParams class which serves as the base class for layouts parameters.

   View class represents the basic building block for user interface components. A View occupies a rectangular area on the screen and is responsible for drawing and event handling. View is the base class for widgets, which are used to create interactive UI components (buttons, text fields, etc.).

2. Example : ViewGroup (LinearLayout), View (TextView)

Reference

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

Answer from: Removing duplicated rows from R data frame

Anyone looking for this functionality past 2018: it's much cleaner to do this with just CSS using position: sticky.

position: sticky doesn't work with some table elements (thead/tr) in Chrome. You can move sticky to tds/ths of tr you need to be sticky. Like this:

thead tr:nth-child(1) th {
  background: white;
  position: sticky;
  top: 0;
  z-index: 10;
}

Try this:

SELECT * 
  FROM  (
        SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast 
        FROM users 
    ) a
WHERE firstlast = "Bob Michael Jones"

nvarchar is going to have significant overhead in memory, storage, working set and indexing, so if the specs dictate that it really will never be necessary, don't bother.

I would not have a hard and fast "always nvarchar" rule because it can be a complete waste in many situations - particularly ETL from ASCII/EBCDIC or identifiers and code columns which are often keys and foreign keys.

On the other hand, there are plenty of cases of columns, where I would be sure to ask this question early and if I didn't get a hard and fast answer immediately, I would make the column nvarchar.

I usually loop over the array and attach a comma after every entry in the string. After the loop I delete the last comma again.

Maybe not the best way, but less expensive than checking every time if it's the last object in the loop I guess.

That's called onload. DOM ready was actually created for the exact reason that onload waited on images. ( Answer taken from Matchu on a simmilar question a while ago. )

window.onload = function () { alert("It's loaded!") }

onload waits for all resources that are part of the document.

in my case, the tortoise icon not showing at all, I tried this and solved my problem :

1. open registry
2. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers
3. delete all folder OneDrive
4. delete all folder SkyDrive

(the point is to place all tortoise folder at top)

5. open TaskManager and kill Explorer
6. re run Explorer through TaskManager

Without more information about the question, the terms 'program' and 'application' are nearly synonymous.

As Saif has indicated, 'application' tends to be used more for non-system related programs. That being said, I don't think it's wrong to describe the operating system as an special application that provides an environment in which to run other applications.

According to the docs, it means the total number throughout history:

In C++11 you can:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  std::make_tuple(dividend / divisor, dividend % divisor);
}

#include <iostream>

int main() {
    using namespace std;

    int quotient, remainder;

    tie(quotient, remainder) = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

In C++17:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

or with structs:

auto divide(int dividend, int divisor) {
    struct result {int quotient; int remainder;};
    return result {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto result = divide(14, 3);

    cout << result.quotient << ',' << result.remainder << endl;

    // or

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

If you set:

hibernate.temp.use_jdbc_metadata_defaults: false

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

A warning about the Jquery Caret plugin.

It will conflict with the Masked Input plugin (or vice versa). Fortunately the Masked Input plugin includes a caret() function of its own, which you can use very similarly to the Caret plugin for your basic needs - $(element).caret().begin or .end

There are two pair of modal events, one is "show" and "shown", the other is "hide" and "hidden". As you can see from the name, hide event fires when modal is about the be close, such as clicking on the cross on the top-right corner or close button or so on. While hidden is fired after the modal is actually close. You can test these events your self. For exampel:

$( '#modal' )
   .on('hide', function() {
       console.log('hide');
   })
   .on('hidden', function(){
       console.log('hidden');
   })
   .on('show', function() {
       console.log('show');
   })
   .on('shown', function(){
      console.log('shown' )
   });

And, as for your question, I think you should listen to the 'hide' event of your modal.

I tried TARGETDIR, INSTALLLOCATION and INSTALLDIR args and still it installed in the default directory. So I viewed the log and there is this arg where it sets the Application Directory and it is being set to default.

MSI (s) (50:94) [09:03:13:374]: Running product '{BDAFD18D-0395-4E72-B295-1EA66A7B80CF}' with elevated privileges: Product is assigned.
MSI (s) (50:94) [09:03:13:374]: PROPERTY CHANGE: Adding APPDIR property. Its value is 'E:\RMP2'.
MSI (s) (50:94) [09:03:13:374]: PROPERTY CHANGE: Adding CURRENTDIRECTORY property. Its value is 'C:\Users\Administrator'.

So I changed the command to have APPDIR instead of the args mentioned above. It worked like a charm.

msiexec /i "path_to_msi" APPDIR="path_to_installation_dir" /q

Add /lv if you want to copy the installation progress to a logfile.

dksnap (https://github.com/kelda/dksnap) automates the process of running pg_dumpall and loading the dump via /docker-entrypoint-initdb.d.

It shows you a list of running containers, and you pick which one you want to backup. The resulting artifact is a regular Docker image, so you can then docker run it, or share it by pushing it to a Docker registry.

(disclaimer: I'm a maintainer on the project)

You can use DataColumn.Ordinal to get the index of the column in the DataTable. So if you need the next column as mentioned use Column.Ordinal + 1:

row[row.Table.Columns["ColumnName"].Ordinal + 1] = someOtherValue;

you are trying to set the 10th element of the array to the array try

data = new int[] {10,20,30,40,50,60,71,80,90,91};

UPDATE: By version 41 of Google Chrome, initMouseEvent seemed to have a changed behavior.

this can be done by simulating ctrl + click (or any other key/event combinations that open a background tab) on a dynamically generated a element with its href attribute set to the desired url

In action: fiddle

function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = "http://www.google.com/";
    var evt = document.createEvent("MouseEvents");
    //the tenth parameter of initMouseEvent sets ctrl key
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
                                true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

tested only on chrome

I had this concern when working on a Rails application with Docker.

My most preferred approach is to generally not use quotes. This includes not using quotes for:

• variables like ${RAILS_ENV}
• values separated by a colon (:) like postgres-log:/var/log/postgresql
• other strings values

I, however, use double-quotes for integer values that need to be converted to strings like:

• docker-compose version like version: "3.8"
• port numbers like "8080:8080"

However, for special cases like booleans, floats, integers, and other cases, where using double-quotes for the entry values could be interpreted as strings, please do not use double-quotes.

Here's a sample docker-compose.yml file to explain this concept:

version: "3"

services:
  traefik:
    image: traefik:v2.2.1
    command:
      - --api.insecure=true # Don't do that in production
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

That's all.

I hope this helps

Neither of the suggestions here were helpful for me. So I had to debug primefaces and found the reason of the problem was:

java.lang.IllegalStateException: No multipart config for servlet fileUpload

Then I have added section into my faces servlet in the web.xml. So that has fixed the problem:

<servlet>
    <servlet-name>main</servlet-name>

        <servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <multipart-config>
            <location>/tmp</location>
            <max-file-size>20848820</max-file-size>
            <max-request-size>418018841</max-request-size>
            <file-size-threshold>1048576</file-size-threshold>
        </multipart-config>
    </servlet>

you could simply type :

background: linear-gradient(_x000D_
    to bottom,_x000D_
    rgba(0,0,0, 0),_x000D_
    rgba(0,0,0, 100)_x000D_
  ),url(../images/image.jpg);

I think this will helpful to you...

    DECLARE @ConstraintName nvarchar(200)
SELECT 
    @ConstraintName = KCU.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS AS RC 
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KCU
    ON KCU.CONSTRAINT_CATALOG = RC.CONSTRAINT_CATALOG  
    AND KCU.CONSTRAINT_SCHEMA = RC.CONSTRAINT_SCHEMA 
    AND KCU.CONSTRAINT_NAME = RC.CONSTRAINT_NAME
WHERE
    KCU.TABLE_NAME = 'TABLE_NAME' AND
    KCU.COLUMN_NAME = 'TABLE_COLUMN_NAME'
IF @ConstraintName IS NOT NULL EXEC('alter table TABLE_NAME drop  CONSTRAINT ' + @ConstraintName)

It will delete foreign Key Constraint based on specific table and column.

It might be easier with vlookup. Try this:

=IFERROR(VLOOKUP(D2,G:H,2,0),"")

The IFERROR() is for no matches, so that it throws "" in such cases.

VLOOKUP's first parameter is the value to 'look for' in the reference table, which is column G and H.

VLOOKUP will thus look for D2 in column G and return the value in the column index 2 (column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.

The last parameter is 0 (or equivalently FALSE) to mean an exact match. That's what you need as opposed to approximate match.

I have found that this works:

$(document).ready(function(){
    $('textarea').bind('input propertychange', function() {
        //do your update here
    }

})

The best solution I've found in this is to create a lookup table with the possible values as a primary key, and create a foreign key to the lookup table.

here i sent jsonobject as parameter //jsonobject={"name":"lucifer","pass":"abc"}//serverUrl = "http://192.168.100.12/testing" //host=192.168.100.12

    StringBuilder sb = new StringBuilder();

    String http = serverUrl;

    HttpURLConnection urlConnection = null;
    try {
        URL url = new URL(http);
        urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.setDoOutput(true);
        urlConnection.setRequestMethod("POST");
        urlConnection.setUseCaches(false);
        urlConnection.setConnectTimeout(50000);
        urlConnection.setReadTimeout(50000);
        urlConnection.setRequestProperty("Content-Type", "application/json");
        urlConnection.setRequestProperty("Host", host);
        urlConnection.connect();
        //You Can also Create JSONObject here 
        OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream());
        out.write(jsonobject);// here i sent the parameter
        out.close();
        int HttpResult = urlConnection.getResponseCode();
        if (HttpResult == HttpURLConnection.HTTP_OK) {
            BufferedReader br = new BufferedReader(new InputStreamReader(
                    urlConnection.getInputStream(), "utf-8"));
            String line = null;
            while ((line = br.readLine()) != null) {
                sb.append(line + "\n");
            }
            br.close();
            Log.e("new Test", "" + sb.toString());
            return sb.toString();
        } else {
            Log.e(" ", "" + urlConnection.getResponseMessage());
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();

In addition to Roman's answer, something like this might be even simpler. Note that I haven't tested it because I do not have access to R right now.

# Note that I use a global variable here
# normally not advisable, but I liked the
# use here to make the code shorter
index <<- 0
new_column = sapply(df$h_no, function(x) {
  if(x == 1) index = index + 1
  return(index)
})

The function iterates over the values in n_ho and always returns the categorie that the current value belongs to. If a value of 1 is detected, we increase the global variable index and continue.

Θ-notation (theta notation) is called tight-bound because it's more precise than O-notation and Ω-notation (omega notation).

If I were lazy, I could say that binary search on a sorted array is O(n²), O(n³), and O(2ⁿ), and I would be technically correct in every case. That's because O-notation only specifies an upper bound, and binary search is bounded on the high side by all of those functions, just not very closely. These lazy estimates would be useless.

Θ-notation solves this problem by combining O-notation and Ω-notation. If I say that binary search is Θ(log n), that gives you more precise information. It tells you that the algorithm is bounded on both sides by the given function, so it will never be significantly faster or slower than stated.

To check a service's state, use sc query <SERVICE_NAME>. For if blocks in batch files, check the documentation.

The following code will check the status of the service MyServiceName and start it if it is not running (the if block will be executed if the service is not running):

for /F "tokens=3 delims=: " %%H in ('sc query "MyServiceName" ^| findstr "        STATE"') do (
  if /I "%%H" NEQ "RUNNING" (
   REM Put your code you want to execute here
   REM For example, the following line
   net start "MyServiceName"
  )
)

Explanation of what it does:

1. Queries the properties of the service.
2. Looks for the line containing the text "STATE"
3. Tokenizes that line, and pulls out the 3rd token, which is the one containing the state of the service.
4. Tests the resulting state against the string "RUNNING"

As for your second question, the argument you will want to pass to net start is the service name, not the display name.

What you are currently doing is checking whether neither the start_date nor the end_date fall within the range of the dates given.

I guess what you are really looking for is a record which does not fit in the date range given. If so, use the query below.

SELECT * 
    FROM `test_table` 
    WHERE  CAST('2009-12-15' AS DATE) > start_date  AND  CAST('2010-01-02' AS DATE) < end_date

You have to install a Selenium Server (a Hub) and register your remote WebDriver to it. Then, your client will talk to the Hub which will find a matching WebDriver to execute your test.

You can have a look at here for more information.

In RStudio, to increase:

file.edit(file.path("~", ".Rprofile"))

then in .Rprofile type this and save

invisible(utils::memory.limit(size = 60000))

To decrease: open .Rprofile

invisible(utils::memory.limit(size = 30000))

save and restart RStudio.

Graphically, the cron syntax for Quarz is (source):

+-------------------- second (0 - 59)
|  +----------------- minute (0 - 59)
|  |  +-------------- hour (0 - 23)
|  |  |  +----------- day of month (1 - 31)
|  |  |  |  +-------- month (1 - 12)
|  |  |  |  |  +----- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |  |  +-- year [optional]
|  |  |  |  |  |  |
*  *  *  *  *  *  * command to be executed 

So if you want to run a command every 30 minutes you can say either of these:

0 0/30 * * * * ?
0 0,30 * * * * ?

You can check crontab expressions using either of these:

• crontab.guru — (disclaimer: I am not related to that page at all, only that I find it very useful). This page uses UNIX style of cron that does not have seconds in it, while Spring does as the first field.
• Cron Expression Generator & Explainer - Quartz — cron formatter, allowing seconds also.

I can't tell from the context you supply, but if it's something you just need to do at app startup, you can still use Server.MapPath in WebApiHttpApplication; e.g. in Application_Start().

I'm just answering your direct question; the already-mentioned HostingEnvironment.MapPath() is probably the preferred solution.

If you've done a user installation, you'll need to add the right folder to your PATH variable.

PYTHON_BIN_PATH="$(python3 -m site --user-base)/bin"
PATH="$PATH:$PYTHON_BIN_PATH"

See pipenv's installation instructions

You can comput hashes using MessageDigest, but this is wrong in terms of security. Hashes are not to be used for storing passwords, as they are easily breakable.

You should use another algorithm like bcrypt, PBKDF2 and scrypt to store you passwords. See here.

This gets parent if it is a div. Then it gets class.

var div = $(this).parent("div");
var _class = div.attr("class");

Is it as optional functionality.

If you won't provide it when user will try to purchase non-consumable product AppStore will restore old transaction. But your app will think that this is new transaction.

If you will provide restore mechanism then your purchase manager will see restored transaction.

If app should distinguish this options then you should provide functionality for restoring previously purchased products.

References are not pointers.

8.3.2/1:

A reference shall be initialized to refer to a valid object or function. [Note: in particular, a null reference cannot exist in a well-defined program, because the only way to create such a reference would be to bind it to the “object” obtained by dereferencing a null pointer, which causes undefined behavior. As described in 9.6, a reference cannot be bound directly to a bit-field. ]

1.9/4:

Certain other operations are described in this International Standard as undefined (for example, the effect of dereferencing the null pointer)

As Johannes says in a deleted answer, there's some doubt whether "dereferencing a null pointer" should be categorically stated to be undefined behavior. But this isn't one of the cases that raise doubts, since a null pointer certainly does not point to a "valid object or function", and there is no desire within the standards committee to introduce null references.

If you're not using Homebrew, this is what I just did on MAC OS X Lion (10.7.5):

1. Get the latest version of the ZSH sourcecode

2. Untar the download into its own directory then install: ./configure && make && make test && sudo make install

3. This installs the the zsh binary at /usr/local/bin/zsh.

4. You can now use the shell by loading up a new terminal and executing the binary directly, but you'll want to make it your default shell...

5. To make it your default shell you must first edit /etc/shells and add the new path. Then you can either run chsh -s /usr/local/bin/zsh or go to System Preferences > Users & Groups > right click your user > Advanced Options... > and then change "Login shell".

6. Load up a terminal and check you're now in the correct version with echo $ZSH_VERSION. (I wasn't at first, and it took me a while to figure out I'd configured iTerm to use a specific shell instead of the system default).

You should also consider the OPTIMIZE FOR n ROWS clause. More details on all of this in the DB2 LUW documentation in the Guidelines for restricting SELECT statements topic:

• The OPTIMIZE FOR clause declares the intent to retrieve only a subset of the result or to give priority to retrieving only the first few rows. The optimizer can then choose access plans that minimize the response time for retrieving the first few rows.

Another simple way that's supported by all browsers would be:

HTML:

<form class="disabled">
  <input type="text" name="name" />
  <input type="radio" name="gender" value="male">
  <input type="radio" name="gender" value="female">
  <input type="checkbox" name="vegetarian">
</form>

CSS:

.disabled {
  pointer-events: none;
  opacity: .4;
}

But be aware, that the tabbing still works with this approach and the elements with focus can still be manipulated by the user.

err = diffsnorm(data, U, s[:pca_components], Va.T)
print('pca by doug time: %.3fms, error: %E' % (time*1000/repeat, err))

pca_mark is the pca in Mark's answer.

pca_doug is the pca in doug's answer.

Here is an example output (but the result depends very much on the data size and pca_components, so I'd recommend to run your own test with your own data. Also, facebook's pca is optimized for normalized data, so it will be faster and more accurate in that case):

svd time: 3212.228ms, error: 1.907320E-10
matplotlib PCA time: 879.210ms, error: 2.478853E+05
facebook pca time: 485.483ms, error: 1.260335E+04
sklearn PCA time: 169.832ms, error: 7.469847E+07
pca by Mark time: 293.758ms, error: 1.713129E+02
pca by doug time: 300.326ms, error: 1.707492E+02

EDIT:

The diffsnorm function from fbpca calculates the spectral-norm error of a Schur decomposition.

Here are some useful delete operations for mongodb using mongo shell

To delete particular document in collections: db.mycollection.remove( {name:"stack"} )

To delete all documents in collections: db.mycollection.remove()

To delete any particular collection : db.mycollection.drop()

to delete database : first go to that database by use mydb command and then

db.dropDatabase()

If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.

You can download c4droid and then install the GCC plugin and install to your SD. From the shell I just traverse to the directory where the GCC binary is and then call it to make an on board executable.

find / -name gcc

/mnt/sdcard/Android/data/com.n0n3m4.droidc/files/gcc/bin/arm-linux-androideabi-gcc

cat > test.c

#include<stdio.h>
int main(){ 
 printf("hello arm!\n");
return 0;
}

./arm-linux-androideabi-gcc test.c -o test

./test

hello arm!

No one has mentioned using negative inset values for legend. Here is an example, where the legend is to the right of the plot, aligned to the top (using keyword "topright").

# Random data to plot:
A <- data.frame(x=rnorm(100, 20, 2), y=rnorm(100, 20, 2))
B <- data.frame(x=rnorm(100, 21, 1), y=rnorm(100, 21, 1))

# Add extra space to right of plot area; change clipping to figure
par(mar=c(5.1, 4.1, 4.1, 8.1), xpd=TRUE)

# Plot both groups
plot(y ~ x, A, ylim=range(c(A$y, B$y)), xlim=range(c(A$x, B$x)), pch=1,
               main="Scatter plot of two groups")
points(y ~ x, B, pch=3)

# Add legend to top right, outside plot region
legend("topright", inset=c(-0.2,0), legend=c("A","B"), pch=c(1,3), title="Group")

The first value of inset=c(-0.2,0) might need adjusting based on the width of the legend.

Not a big deal, but most regex engines support the POSIX character classes, and there's [:xdigit:] for matching hex characters, which is simpler than the common 0-9a-fA-F stuff.

So, the regex as requested (ie. with optional 0x) is: /(0x)?[[:xdigit:]]+/

You need a SQL profiler, which actually runs outside SQL Management Studio. If you have a paid version of SQL Server (like the developer edition), it should be included in that as another utility.

If you're using a free edition (SQL Express), they have freeware profiles that you can download. I've used AnjLab's profiler (available at http://sites.google.com/site/sqlprofiler), and it seemed to work well.

Here is a way to write data from a dataframe into an excel file by different IDs and into different tabs (sheets) by another ID associated to the first level id. Imagine you have a dataframe that has email_address as one column for a number of different users, but each email has a number of 'sub-ids' that have all the data.

data <- tibble(id = c(1,2,3,4,5,6,7,8,9), email_address = c(rep('[email protected]',3), rep('[email protected]', 3), rep('[email protected]', 3)))

So ids 1,2,3 would be associated with [email protected]. The following code splits the data by email and then puts 1,2,3 into different tabs. The important thing is to set append = True when writing the .xlsx file.

temp_dir <- tempdir()

for(i in unique(data$email_address)){
    
  data %>% 
    filter(email_address == i) %>% 
    arrange(id) -> subset_data
  
  for(j in unique(subset_data$id)){
    write.xlsx(subset_data %>% filter(id == j), 
      file = str_c(temp_dir,"/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0- 
       9._%+-]+"),'_', Sys.Date(), '.xlsx'), 
      sheetName = as.character(j), 
      append = TRUE)}
 
  }

The regex gets the name from the email address and puts it into the file-name.

Hope somebody finds this useful. I'm sure there's more elegant ways of doing this but it works.

Btw, here is a way to then send these individual files to the various email addresses in the data.frame. Code goes into second loop [j]

  send.mail(from = "[email protected]",
            to = i,
          subject = paste("Your report for", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"), 'on', Sys.Date()),
          body = "Your email body",
          authenticate = TRUE,
          smtp = list(host.name = "XXX", port = XXX,
                      user.name = Sys.getenv("XXX"), passwd = Sys.getenv("XXX")),
          attach.files = str_c(temp_dir, "/your_filename_", str_extract(i, pattern = "\\b[A-Za-z0-9._%+-]+"),'_', Sys.Date(), '.xlsx'))

You need to add your ssh key to your git account,if it throws error then delete previous ssh key and create a new ssh key then add.

Regarding which python version to use, Mac OS usually ships an old version of python. It's a good idea to upgrade to a newer version. You can download a .dmg from http://www.python.org/download/ . If you do that, remember to update the path. You can find the exact commands here http://farmdev.com/thoughts/66/python-3-0-on-mac-os-x-alongside-2-6-2-5-etc-/

Also, spark is a nice little bar graph in your shell.

Well, the simple regex is this:

/^dbo\..*_fn$/

It would be better, however, to use the string manipulation functionality of whatever programming language you're using to slice off the first four and the last three characters of the string and check whether they're what you want.

I've tried many times.

And at last I just put autoindex on; in http but outside of server, and it's OK.

There may be two approaches depending on your server side logic.

Approach 1: When server is not smart enough to handle object states.

You could send all cached record unique id’s to server, for example ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"] and a boolean parameter to know whether you are requesting new records(pull to refresh) or old records(load more).

Your sever should responsible to return new records(load more records or new records via pull to refresh) as well as id’s of deleted records from ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"].

Example:- If you are requesting load more then your request should look something like this:-

{
        "isRefresh" : false,
        "cached" : ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10"]
}

Now suppose you are requesting old records(load more) and suppose "id2" record is updated by someone and "id5" and "id8" records is deleted from server then your server response should look something like this:-

{
        "records" : [
{"id" :"id2","more_key":"updated_value"},
{"id" :"id11","more_key":"more_value"},
{"id" :"id12","more_key":"more_value"},
{"id" :"id13","more_key":"more_value"},
{"id" :"id14","more_key":"more_value"},
{"id" :"id15","more_key":"more_value"},
{"id" :"id16","more_key":"more_value"},
{"id" :"id17","more_key":"more_value"},
{"id" :"id18","more_key":"more_value"},
{"id" :"id19","more_key":"more_value"},
{"id" :"id20","more_key":"more_value"}],
        "deleted" : ["id5","id8"]
}

But in this case if you’ve a lot of local cached records suppose 500, then your request string will be too long like this:-

{
        "isRefresh" : false,
        "cached" : ["id1","id2","id3","id4","id5","id6","id7","id8","id9","id10",………,"id500"]//Too long request
}

Approach 2: When server is smart enough to handle object states according to date.

You could send the id of first record and the last record and previous request epoch time. In this way your request is always small even if you’ve a big amount of cached records

Example:- If you are requesting load more then your request should look something like this:-

{
        "isRefresh" : false,
        "firstId" : "id1",
        "lastId" : "id10",
        "last_request_time" : 1421748005
}

Your server is responsible to return the id’s of deleted records which is deleted after the last_request_time as well as return the updated record after last_request_time between "id1" and "id10" .

{
        "records" : [
{"id" :"id2","more_key":"updated_value"},
{"id" :"id11","more_key":"more_value"},
{"id" :"id12","more_key":"more_value"},
{"id" :"id13","more_key":"more_value"},
{"id" :"id14","more_key":"more_value"},
{"id" :"id15","more_key":"more_value"},
{"id" :"id16","more_key":"more_value"},
{"id" :"id17","more_key":"more_value"},
{"id" :"id18","more_key":"more_value"},
{"id" :"id19","more_key":"more_value"},
{"id" :"id20","more_key":"more_value"}],
        "deleted" : ["id5","id8"]
}

Pull To Refresh:-

Load More

You don't need a function at all. You can work on a whole column directly.

Example data:

>>> df = pd.DataFrame({'a': [100, 1000], 'b': [200, 2000], 'c': [300, 3000]})
>>> df

      a     b     c
0   100   200   300
1  1000  2000  3000

Half all the values in column a:

>>> df.a = df.a / 2
>>> df

     a     b     c
0   50   200   300
1  500  2000  3000

If this isn't a good solution for any reason, please let me know. It worked fine for me.

What I did is to hide the Sidebar and then make appear the navbar with breakpoints

@media screen and (max-width: 771px) {
    #fixed-sidebar {
        display: none;
    }
    #navbar-superior {
        display: block !important;
    }
}

I have installed XAMPP version 7.3.11, After starting the Apache and other services, go to volumes tab on XAMPP, and click on mount button,

And then Click on explore button,

You will get Finder open up with this,

you should be searching about how to add favicon.ico . You can try adding favicon.ico directly in your html pages like this

<link rel="shortcut icon" href="/favicon.png" type="image/png">
<link rel="shortcut icon" type="image/png" href="http://www.example.com/favicon.png" />

Or you can update that in your webserver. It is advised to add in your webserver as you don't need to add this in each of your html pages (assuming no includes).

To add in your apache place the favicon.ico in your root website director and add this in httpd.conf

AddType image/x-icon .ico

Just like any other click event, you can use jQuery to register an element, set an id to the element and listen to events like so:

$('#myButton').on('click', function(event) {
  event.preventDefault(); // To prevent following the link (optional)
  ...
});

You can also use inline javascript in the onclick attribute:

<a ... onclick="myFunc();">..</a>

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

I tried using IFTTT and many other services but all were doing things or post from Instagram to another platform not to Instagram. I read more to found Instagram does not provide any such API as of now.

Using blue stack is again involving heavy installation and doing things manually only.

However, you can use your Google Chrome on the desktop version to make a post on Instagram. It needs a bit tweak.

1. Open your chrome and browse Instagram.com
2. Go to inspect element by right clicking on chrome.
3. From top right corener menu drop down on developer tools, select more tool.
4. Further select network conditions.
5. In the network selection section, see the second section there named user agent.
6. Uncheck select automatically, and select chrome for Android from the list of given user agent.
7. Refresh your Instagram.com page.

You will notice a change in UI and the option to make a post on Instagram. Your life is now easy. Let me know an easier way if you can find any.

I wrote on https://www.inteligentcomp.com/2018/11/how-to-upload-to-instagram-from-pc-mac.html about it.

That should do it hope I helped!

I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing } character. What's the length of result1 versus result2? I'll note that result2 as you've quoted it has 169 characters.

GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t, \n, \r, and space count as whitespace. In particular, note that trailing NUL (\0) characters do not count as whitespace and will cause this error.

If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);

The 'keyof' solution mentioned above works. But if the variable is used only once e.g looping through an object etc, you can also typecast it.

for (const key in someObject) {
    sampleObject[key] = someObject[key as keyof ISomeObject];
}

After a lot of searching ,i found the problem was in my project dll file .i cleaned and rebuild my project when there were compilation errors ... simple solution is to remove all compilation errors in all pages either by removing contents or commenting lines ,then clean and rebuild your project ... this will sort out your problem ..

Another flavor for same "proxy for nuget": alternatively you can set your nuget proxing settings to connect through fiddler. Below cmd will save proxy settings in in default nuget config file for user at %APPDATA%\NuGet\NuGet.Config

nuget config -Set HTTP_PROXY=http://127.0.0.1:8888

Whenever you need nuget to reach out the internet, just open Fiddler, asumming you have fiddler listening on default port 8888.

This configuration is not sensitive to passwork changes because fiddler will resolve any authentication with up stream proxy for you.

USE:

 >>> a[[0,1,3]][:,[0,2]]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

OR:

>>> a[[0,1,3],::2]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

Follow the following steps if you are using proxy server:

1. Open Eclipse
2. Window >> Android SDK Manager >> Option
3. Input your proxy server and port.

Hope this helps.

It is indeed much less simple than it seems :-) Nick's suggestion is a good one.

To get started, keep in mind that any worthwhile comparison method will essentially work by converting the images into a different form -- a form which makes it easier to pick similar features out. Usually, this stuff doesn't make for very light reading ...


One of the simplest examples I can think of is simply using the color space of each image. If two images have highly similar color distributions, then you can be reasonably sure that they show the same thing. At least, you can have enough certainty to flag it, or do more testing. Comparing images in color space will also resist things such as rotation, scaling, and some cropping. It won't, of course, resist heavy modification of the image or heavy recoloring (and even a simple hue shift will be somewhat tricky).

http://en.wikipedia.org/wiki/RGB_color_space
http://upvector.com/index.php?section=tutorials&subsection=tutorials/colorspace

Another example involves something called the Hough Transform. This transform essentially decomposes an image into a set of lines. You can then take some of the 'strongest' lines in each image and see if they line up. You can do some extra work to try and compensate for rotation and scaling too -- and in this case, since comparing a few lines is MUCH less computational work than doing the same to entire images -- it won't be so bad.

http://homepages.inf.ed.ac.uk/amos/hough.html
http://rkb.home.cern.ch/rkb/AN16pp/node122.html
http://en.wikipedia.org/wiki/Hough_transform

Check for "projtemp" and then check if the previous one is a number entry (like 19,18..etc..) if that is so then get the row no of that proj temp ....

and if that is not so ..then re-check that the previous entry is projtemp or a number entry ...

Why do I need the descriptor class?

It gives you extra control over how attributes work. If you're used to getters and setters in Java, for example, then it's Python's way of doing that. One advantage is that it looks to users just like an attribute (there's no change in syntax). So you can start with an ordinary attribute and then, when you need to do something fancy, switch to a descriptor.

An attribute is just a mutable value. A descriptor lets you execute arbitrary code when reading or setting (or deleting) a value. So you could imagine using it to map an attribute to a field in a database, for example – a kind of ORM.

Another use might be refusing to accept a new value by throwing an exception in __set__ – effectively making the "attribute" read only.

What is instance and owner here? (in __get__). What is the purpose of these parameters?

This is pretty subtle (and the reason I am writing a new answer here - I found this question while wondering the same thing and didn't find the existing answer that great).

A descriptor is defined on a class, but is typically called from an instance. When it's called from an instance both instance and owner are set (and you can work out owner from instance so it seems kinda pointless). But when called from a class, only owner is set – which is why it's there.

This is only needed for __get__ because it's the only one that can be called on a class. If you set the class value you set the descriptor itself. Similarly for deletion. Which is why the owner isn't needed there.

How would I call/use this example?

Well, here's a cool trick using similar classes:

class Celsius:

    def __get__(self, instance, owner):
        return 5 * (instance.fahrenheit - 32) / 9

    def __set__(self, instance, value):
        instance.fahrenheit = 32 + 9 * value / 5


class Temperature:

    celsius = Celsius()

    def __init__(self, initial_f):
        self.fahrenheit = initial_f


t = Temperature(212)
print(t.celsius)
t.celsius = 0
print(t.fahrenheit)

(I'm using Python 3; for python 2 you need to make sure those divisions are / 5.0 and / 9.0). That gives:

100.0
32.0

Now there are other, arguably better ways to achieve the same effect in python (e.g. if celsius were a property, which is the same basic mechanism but places all the source inside the Temperature class), but that shows what can be done...

css:

header.sticky {
  font-size: 24px;
  line-height: 48px;
  height: 48px;
  background: #efc47D;
  text-align: left;
  padding-left: 20px;
}

JS:

$(window).scroll(function() {
 if ($(this).scrollTop() > 100){  
    $('header').addClass("sticky");
  }
  else{
    $('header').removeClass("sticky");
  }
});

Create a batch file with the following lines:

start foo.exe
start bar.exe
start baz.exe 

The start command runs your command in a new window, so all 3 commands would run asynchronously.

if you use ubuntu 16.04 (maybe and above) just do this

 sudo phpenmod mysqli
 sudo service php7.0-fpm restart

In my case, there were rules for IIS URL Rewrite module but I didn't have that module installed. You should check your web.config if there are any modules included but not installed.

I found that android:textColor="@android:color/secondary_text_dark" provides a closer result to the default TextView color than android:textColor="@android:color/tab_indicator_text". I suppose you have to switch between secondary_text_dark/light depending on the Theme you are using

When to use LIBXML_NOCDATA ?

I add the issue when transforming XML to JSON.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo json_encode($xml, true); 
/* prints
   {
     "content": {}
   }
 */

When accessing the SimpleXMLElement object, It gets the CDATA :

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo $xml->content; 
/* prints
   Hello, world!
*/

I makes sense to use LIBXML_NOCDATA because json_encode don't access the SimpleXMLElement to trigger the string casting feature, I'm guessing a __toString() equivalent.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>", null, LIBXML_NOCDATA);
echo json_encode($xml);
/*
 {
   "content": "Hello, world!"
 }
*/

Use try-catch to avoid it:

var result = null;
try {
  // if jQuery
  result = $.parseJSON(JSONstring);
  // if plain js
  result = JSON.parse(JSONstring);
}
catch(e) {
  // forget about it :)
}

Having tried various approaches to move a file or folder from one Git repository to another, the only one which seems to work reliably is outlined below.

It involves cloning the repository you want to move the file or folder from, moving that file or folder to the root, rewriting Git history, cloning the target repository and pulling the file or folder with history directly into this target repository.

Stage One

1. Make a copy of repository A as the following steps make major changes to this copy which you should not push!

   git clone --branch <branch> --origin origin --progress \
     -v <git repository A url>
   # eg. git clone --branch master --origin origin --progress \
   #   -v https://username@giturl/scm/projects/myprojects.git
   # (assuming myprojects is the repository you want to copy from)
   

2. cd into it

   cd <git repository A directory>
   #  eg. cd /c/Working/GIT/myprojects
   

3. Delete the link to the original repository to avoid accidentally making any remote changes (eg. by pushing)

   git remote rm origin
   

4. Go through your history and files, removing anything that is not in directory 1. The result is the contents of directory 1 spewed out into to the base of repository A.

   git filter-branch --subdirectory-filter <directory> -- --all
   # eg. git filter-branch --subdirectory-filter subfolder1/subfolder2/FOLDER_TO_KEEP -- --all
   

5. For single file move only: go through what's left and remove everything except the desired file. (You may need to delete files you don't want with the same name and commit.)

   git filter-branch -f --index-filter \
   'git ls-files -s | grep $'\t'FILE_TO_KEEP$ |
   GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
   git update-index --index-info && \
   mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE || echo "Nothing to do"' --prune-empty -- --all
   # eg. FILE_TO_KEEP = pom.xml to keep only the pom.xml file from FOLDER_TO_KEEP
   

Stage Two

1. Cleanup step

   git reset --hard
   

2. Cleanup step

   git gc --aggressive
   

3. Cleanup step

   git prune
   

You may want to import these files into repository B within a directory not the root:

1. Make that directory

   mkdir <base directory>             eg. mkdir FOLDER_TO_KEEP
   

2. Move files into that directory

   git mv * <base directory>          eg. git mv * FOLDER_TO_KEEP
   

3. Add files to that directory

   git add .
   

4. Commit your changes and we’re ready to merge these files into the new repository

   git commit
   

Stage Three

1. Make a copy of repository B if you don’t have one already

   git clone <git repository B url>
   # eg. git clone https://username@giturl/scm/projects/FOLDER_TO_KEEP.git
   

   (assuming FOLDER_TO_KEEP is the name of the new repository you are copying to)

2. cd into it

   cd <git repository B directory>
   #  eg. cd /c/Working/GIT/FOLDER_TO_KEEP
   

3. Create a remote connection to repository A as a branch in repository B

   git remote add repo-A-branch <git repository A directory>
   # (repo-A-branch can be anything - it's just an arbitrary name)
   
   # eg. git remote add repo-A-branch /c/Working/GIT/myprojects
   

4. Pull from this branch (containing only the directory you want to move) into repository B.

   git pull repo-A-branch master --allow-unrelated-histories
   

   The pull copies both files and history. Note: You can use a merge instead of a pull, but pull works better.

5. Finally, you probably want to clean up a bit by removing the remote connection to repository A

   git remote rm repo-A-branch
   

6. Push and you’re all set.

   git push
   

You can also use the following code:

<?php
$filename = $_GET["nama"];
$contenttype = "application/force-download";
header("Content-Type: " . $contenttype);
header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";");
readfile("your file uploaded path".$filename);
exit();
?>

I encountered a similar problem. And I found the solution to be totally unrelated to the error. The trick was renaming the assembly name. Solution: VS 2013 -> Project properties -> Application tab -> AssemblyName property changed to new name < 25 chars

Did something like that once:

CREATE TABLE exclusions(excl VARCHAR(250));
INSERT INTO exclusions(excl)
VALUES
       ('%timeline%'),
       ('%Placeholders%'),
       ('%Stages%'),
       ('%master_stage_1205x465%'),
       ('%Accessories%'),
       ('%chosen-sprite.png'),
('%WebResource.axd');
GO
CREATE VIEW ToBeDeleted AS 
SELECT * FROM chunks
       WHERE chunks.file_id IN
       (
       SELECT DISTINCT
             lf.file_id
       FROM LargeFiles lf
       WHERE lf.file_id NOT IN
             (
             SELECT DISTINCT
                    lf.file_id
             FROM LargeFiles lf
                LEFT JOIN exclusions e ON(lf.URL LIKE e.excl)
                WHERE e.excl IS NULL
             )
       );
GO
CHECKPOINT
GO
SET NOCOUNT ON;
DECLARE @r INT;
SET @r = 1;
WHILE @r>0

BEGIN
    DELETE TOP (10000) FROM ToBeDeleted;
    SET @r = @@ROWCOUNT  
END
GO

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

Expanding Rentering.com's answer, in scenarios where a whole graph of many types is to be taken care of, and you're looking for a strongly typed solution, this class can help, see usage (fluent) below. It operates as either a black-list or white-list per type. A type cannot be both (Gist - also contains global ignore list).

public class PropertyFilterResolver : DefaultContractResolver
{
  const string _Err = "A type can be either in the include list or the ignore list.";
  Dictionary<Type, IEnumerable<string>> _IgnorePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  Dictionary<Type, IEnumerable<string>> _IncludePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  public PropertyFilterResolver SetIgnoredProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null) return this;

    if (_IncludePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IgnorePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  public PropertyFilterResolver SetIncludedProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null)
      return this;

    if (_IgnorePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IncludePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
  {
    var properties = base.CreateProperties(type, memberSerialization);

    var isIgnoreList = _IgnorePropertiesMap.TryGetValue(type, out IEnumerable<string> map);
    if (!isIgnoreList && !_IncludePropertiesMap.TryGetValue(type, out map))
      return properties;

    Func<JsonProperty, bool> predicate = jp => map.Contains(jp.PropertyName) == !isIgnoreList;
    return properties.Where(predicate).ToArray();
  }

  string GetPropertyName<TSource, TProperty>(
  Expression<Func<TSource, TProperty>> propertyLambda)
  {
    if (!(propertyLambda.Body is MemberExpression member))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a method, not a property.");

    if (!(member.Member is PropertyInfo propInfo))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a field, not a property.");

    var type = typeof(TSource);
    if (!type.GetTypeInfo().IsAssignableFrom(propInfo.DeclaringType.GetTypeInfo()))
      throw new ArgumentException($"Expresion '{propertyLambda}' refers to a property that is not from type '{type}'.");

    return propInfo.Name;
  }
}

Usage:

var resolver = new PropertyFilterResolver()
  .SetIncludedProperties<User>(
    u => u.Id, 
    u => u.UnitId)
  .SetIgnoredProperties<Person>(
    r => r.Responders)
  .SetIncludedProperties<Blog>(
    b => b.Id)
  .Ignore(nameof(IChangeTracking.IsChanged)); //see gist

I have used POI.

If you use that, keep on eye those cell formatters: create one and use it several times instead of creating each time for cell, it isa huge memory consumption difference or large data.

uint16_t is guaranteed to be a unsigned integer that is 16 bits large

unsigned short int is guaranteed to be a unsigned short integer, where short integer is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer is 16 bits large.

Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler

Minimum Type Limits

Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Type Minimum Range

signed char     -127 to +127
unsigned char      0 to 255
short int     -32767 to +32767
unsigned short int 0 to 65535

If you don't wan't to use ng-model there is ng-value you can try.

Here's the fiddle for this: http://jsfiddle.net/Rg9sG/1/

Would a dataframe of NAs work? something like:

data.frame(matrix(NA, nrow = 2, ncol = 3))

if you need to be more specific about the data type then may prefer: NA_integer_, NA_real_, NA_complex_, or NA_character_ instead of just NA which is logical

Something else that may be more specific that the NAs is:

data.frame(matrix(vector(mode = 'numeric',length = 6), nrow = 2, ncol = 3))

where the mode can be of any type. See ?vector

Neither. You set the isolation level to READ UNCOMMITTED which is always better than giving individual lock hints. Or, better still, if you care about details like consistency, use snapshot isolation.

There is also one thing to mention. If you need a non global constant, you should use static keyword.

Example

// In your *.m file
static NSString * const kNSStringConst = @"const value";

Because of the static keyword, this const is not visible outside of the file.

Minor correction by @QuinnTaylor: static variables are visible within a compilation unit. Usually, this is a single .m file (as in this example), but it can bite you if you declare it in a header which is included elsewhere, since you'll get linker errors after compilation
