Programs & Examples On #Render to texture

Mathias Lin code working beautifully. However, you might want to consider changing this part inside drawPath method:

 if (lngLat.length >= 2 && gp1.getLatitudeE6() > 0 && gp1.getLongitudeE6() > 0
                    && gp2.getLatitudeE6() > 0 && gp2.getLongitudeE6() > 0) {

GeoPoint can be less than zero as well, I switch mine to:

     if (lngLat.length >= 2 && gp1.getLatitudeE6() != 0 && gp1.getLongitudeE6() != 0
                    && gp2.getLatitudeE6() != 0 && gp2.getLongitudeE6() != 0) {

Thank you :D

With the echo approach, if you are on macOS/BSD like me, lose the -n switch that other people suggest. And I like to define a variable for the text.

So it would be like this:

Header="my complex header that may have difficult chars \"like these quotes\" and line breaks \n\n "

{ echo "$Header"; cat "old.txt"; } > "new.txt"
mv new.txt old.txt

To load your data in WebView. Call loadData() method of WebView

webView.loadData(yourData, "text/html; charset=utf-8", "UTF-8");

You can check this example

Shadow + Border + Corner Radius

    scrollview.backgroundColor = [UIColor whiteColor]; 
    CALayer *ScrlViewLayer = [scrollview layer];
    [ScrlViewLayer setMasksToBounds:NO ];
    [ScrlViewLayer setShadowColor:[[UIColor lightGrayColor] CGColor]];
    [ScrlViewLayer setShadowOpacity:1.0 ];
    [ScrlViewLayer setShadowRadius:6.0 ];
    [ScrlViewLayer setShadowOffset:CGSizeMake( 0 , 0 )];
    [ScrlViewLayer setShouldRasterize:YES];
    [ScrlViewLayer setCornerRadius:5.0];
    [ScrlViewLayer setBorderColor:[UIColor lightGrayColor].CGColor];
    [ScrlViewLayer setBorderWidth:1.0];
    [ScrlViewLayer setShadowPath:[UIBezierPath bezierPathWithRect:scrollview.bounds].CGPath];

Go into options. You most likely have 'Manual Sort" turned on. You need to go and change to radio button to "ascending > date". You can also right click the row/column, "more sorting options". It took me forever to find this solution...

In my case the underlying system account through which the package was running was locked out. Once we got the system account unlocked and reran the package, it executed successfully. The developer said that he got to know of this while debugging wherein he directly tried to connect to the server and check the status of the connection.

According to the docs (http://ca3.php.net/language.oop5.cloning):

$a = clone $b;

It can be done this way as well:

$('input', '#div').each(function () {
    console.log($(this)); //log every element found to console output
});

In my specific case I seemed to have been missing the dependency

 <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->

Never parallelize an infinite stream with a limit. Here is what happens:

    public static void main(String[] args) {
        // let's count to 1 in parallel
        System.out.println(
            IntStream.iterate(0, i -> i + 1)
                .parallel()
                .skip(1)
                .findFirst()
                .getAsInt());
    }

Result

    Exception in thread "main" java.lang.OutOfMemoryError
        at ...
        at java.base/java.util.stream.IntPipeline.findFirst(IntPipeline.java:528)
        at InfiniteTest.main(InfiniteTest.java:24)
    Caused by: java.lang.OutOfMemoryError: Java heap space
        at java.base/java.util.stream.SpinedBuffer$OfInt.newArray(SpinedBuffer.java:750)
        at ...

Same if you use .limit(...)

Explanation here: Java 8, using .parallel in a stream causes OOM error

Similarly, don't use parallel if the stream is ordered and has much more elements than you want to process, e.g.

public static void main(String[] args) {
    // let's count to 1 in parallel
    System.out.println(
            IntStream.range(1, 1000_000_000)
                    .parallel()
                    .skip(100)
                    .findFirst()
                    .getAsInt());
}

This may run much longer because the parallel threads may work on plenty of number ranges instead of the crucial one 0-100, causing this to take very long time.

The package it-self is located under /data/app/com.company.appname-xxx.apk.

/data/app/com.company.appname is only a directory created to store files like native libs, cache, ecc...

You can retrieve the package installation path with the Context.getPackageCodePath() function call.

If this is a submit button, use <input type="image" src="..." ... />.

http://www.htmlcodetutorial.com/forms/_INPUT_TYPE_IMAGE.html

If you want to specify the image with CSS, you'll have to use type="submit".

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

We can create a new CSS class for div.

 .div {
      position: absolute;
      left: 150px;
      width: 200px;
      height: 120px;
    }

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

For those that need Powershell to return additional information like the Http StatusCode, here's an example. Included are the two most likely ways to pass in credentials.

Its a slightly modified version of this SO answer:
How to obtain numeric HTTP status codes in PowerShell

$req = [system.Net.WebRequest]::Create($url)
# method 1 $req.UseDefaultCredentials = $true
# method 2 $req.Credentials = New-Object System.Net.NetworkCredential($username, $pwd, $domain); 
try
{
    $res = $req.GetResponse()
}
catch [System.Net.WebException]
{
    $res = $_.Exception.Response
}

$int = [int]$res.StatusCode
$status = $res.StatusCode
return "$int $status"

I run into this when click on a html , it is fixed by adding type = "button" attribute.

For me these two files I have deleted by mistake, after undo these two files and get added in my changes, I was able to commit my changes to git.

By the way, one other possibility is that you do have a too old version of cordova android platform.

Error: Android SDK not found. Make sure that it is installed. If it is not at the default location, set the ANDROID_HOME environment variable.

Then:

cordova platform update android --save

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

Please, take a look at my library: http://sites.google.com/site/easybashgui

It is intended to handle, with the same commands set, indifferently all four big tools "kdialog", "Xdialog", "cdialog" and "zenity", depending if X is running or not, if D.E. is KDE or Gnome or other. There are 15 different functions ( among them there are two called "progress" and "adjust" )...

This is your safest way to do it:

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

Note that if you comment out the commented lines you get a way to add more filtering to your search.

After this it is recommend to check if there is any data returned like:

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

In this two queries, you are using JOIN to query all employees that have at least one department associated.

But, the difference is: in the first query you are returning only the Employes for the Hibernate. In the second query, you are returning the Employes and all Departments associated.

So, if you use the second query, you will not need to do a new query to hit the database again to see the Departments of each Employee.

You can use the second query when you are sure that you will need the Department of each Employee. If you not need the Department, use the first query.

I recomend read this link if you need to apply some WHERE condition (what you probably will need): How to properly express JPQL "join fetch" with "where" clause as JPA 2 CriteriaQuery?

Update

If you don't use fetch and the Departments continue to be returned, is because your mapping between Employee and Department (a @OneToMany) are setted with FetchType.EAGER. In this case, any HQL (with fetch or not) query with FROM Employee will bring all Departments. Remember that all mapping *ToOne (@ManyToOne and @OneToOne) are EAGER by default.

To access services in two different namespaces you can use url like this:

HTTP://<your-service-name>.<namespace-with-that-service>.svc.cluster.local

To list out all your namespaces you can use:

kubectl get namespace

And for service in that namespace you can simply use:

kubectl get services -n <namespace-name>

this will help you.

it is working perfectly by only using html

<p><a href="#"onclick="window.open('http://google.com');window.open('http://yahoo.com');">Click to open Google and Yahoo</a></p>

ULIMIT configuration:

1. Login by root
   
2. vi security/limits.conf

3. Make Below entry

   Ulimit configuration start for website user

   website   soft   nofile    8192
   website   hard   nofile    8192
   website   soft   nproc    4096
   website   hard   nproc    8192
   website   soft   core    unlimited
   website   hard   core    unlimited
   

4. Make Below entry for ALL USER

   Ulimit configuration for every user

   *   soft   nofile    8192
   *   hard   nofile    8192
   *   soft   nproc    4096
   *   hard   nproc    8192
   *   soft   core    unlimited
   *   hard   core    unlimited
   

5. After modifying the file, user need to logoff and login again to see the new values.

To ans to @Jason 's question, in my bash script, I've dome something like this (for my purpose):

dbPass='xxxxxxxx'
.....
## Connect to the DB
PGPASSWORD=${dbPass} psql -h ${dbHost} -U ${myUsr} -d ${myRdb} -P pager=on --set AUTOCOMMIT=off

The another way of doing it is:

psql --set AUTOCOMMIT=off --set ON_ERROR_STOP=on -P pager=on \
     postgresql://${myUsr}:${dbPass}@${dbHost}/${myRdb}

but you have to be very careful about the password: I couldn't make a password with a ' and/or a : to work in that way. So gave up in the end.

1. If you're in a heavily concurrent environment, then pure functional programming is useful. The lack of mutable state makes concurrency almost trivial. See Erlang.

2. In a multiparadigm language, you may want to model some things functionally if the existence of mutable state is must an implementation detail, and thus FP is a good model for the problem domain. For example, see list comprehensions in Python or std.range in the D programming language. These are inspired by functional programming.

Put the elements of the arraylist in the hashMap to count the frequency.

The best solution is to use

Cells(Rows.Count, 1).End(xlUp).Row

since it counts the number of cells until it finds the last one written.

Unlike

Range("A1", sh.Range("A1").End(xlDown)).Rows.Count

what it does is select an "from-to" range and display the row number of the last one busy.
A range implies two minimum values, so ... meanwhile A1 has a value of the range continues to count to the limit (1048576) then it is shown.

Sub test()

Dim sh As Worksheet
Set sh = ThisWorkbook.Sheets(1)
Dim k As Long

    k = Cells(Rows.Count, 1).End(xlUp).Row
    MsgBox k

    k = sh.Range("A1", sh.Range("A1").End(xlDown)).Rows.Count
    MsgBox k

End Sub

Created a directive (ng-repeat with lazy loading) 

which loads data when it reaches to bottom of the page and remove half of the previously loaded data and when it reaches to top of the div again previous data(depending upon on page number) will be loaded removing half of the current data So on DOM at a time only limited data is present which may leads to better performance instead of rendering whole data on load.

Another Solution: If you using UI-grid in the project then  same implementation is there in UI grid with infinite-scroll.

Depending upon height of the division it loads the data and upon scroll new data will be append and previous data will be removed.

Demo with UI grid with infinite-scroll Demo

A similar approach to https://stackoverflow.com/a/15385080/337172 but hopefully more understandable and easy to tweak:

diff \
  --new-line-format="%L" \
  --old-line-format="" \
  --unchanged-line-format="" \
  A1 A2

Whammo blammo (for leading spaces):

SELECT 
    RIGHT(space(60) + cust_name, 60),
    RIGHT(space(60) + cust_address, 60)

OR (for trailing spaces)

SELECT
    LEFT(cust_name + space(60), 60),
    LEFT(cust_address + space(60), 60),

You might need to use a character by character (getc()) loop to ensure you have no buffer overflows and don't truncate the input.

I also had the error message "TypeError: cannot concatenate 'str' and 'int' objects". It turns out that I only just forgot to add str() around a variable when printing it. Here is my code:

def main():_x000D_
 rolling = True; import random_x000D_
 while rolling:_x000D_
  roll = input("ENTER = roll; Q = quit ")_x000D_
  if roll.lower() != 'q':_x000D_
   num = (random.randint(1,6))_x000D_
   print("----------------------"); print("you rolled " + str(num))_x000D_
  else:_x000D_
   rolling = False_x000D_
main()

I know, it was a stupid mistake but for beginners who are very new to python such as myself, it happens.

Make your life easier by using CSS Selectors

I know I have come late to party but I have a nice suggestion for you.

Using BeautifulSoup is already been suggested I would rather prefer using CSS Selectors to scrape data inside HTML

import urllib2
from bs4 import BeautifulSoup

main_url = "http://www.example.com"

main_page_html  = tryAgain(main_url)
main_page_soup = BeautifulSoup(main_page_html)

# Scrape all TDs from TRs inside Table
for tr in main_page_soup.select("table.class_of_table"):
   for td in tr.select("td#id"):
       print(td.text)
       # For acnhors inside TD
       print(td.select("a")[0].text)
       # Value of Href attribute
       print(td.select("a")[0]["href"])

# This is method that scrape URL and if it doesnt get scraped, waits for 20 seconds and then tries again. (I use it because my internet connection sometimes get disconnects)
def tryAgain(passed_url):
    try:
        page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
        return page
    except Exception:
        while 1:
            print("Trying again the URL:")
            print(passed_url)
            try:
                page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
                print("-------------------------------------")
                print("---- URL was successfully scraped ---")
                print("-------------------------------------")
                return page
            except Exception:
                time.sleep(20)
                continue 

$("#grid_GridHeader:first") works as well.

Please try the following code

Uri.fromFile(new File("/sdcard/sample.jpg"))

Not numpy but scipy provides exactly the shift functionality you want,

import numpy as np
from scipy.ndimage.interpolation import shift

xs = np.array([ 0.,  1.,  2.,  3.,  4.,  5.,  6.,  7.,  8.,  9.])

shift(xs, 3, cval=np.NaN)

where default is to bring in a constant value from outside the array with value cval, set here to nan. This gives the desired output,

array([ nan, nan, nan, 0., 1., 2., 3., 4., 5., 6.])

and the negative shift works similarly,

shift(xs, -3, cval=np.NaN)

Provides output

array([  3.,   4.,   5.,   6.,   7.,   8.,   9.,  nan,  nan,  nan])

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

In my case where the last component was non latin characters I did the following in Swift 2.2:

extension String {
 func encodeUTF8() -> String? {
//If I can create an NSURL out of the string nothing is wrong with it
if let _ = NSURL(string: self) {

    return self
}

//Get the last component from the string this will return subSequence
let optionalLastComponent = self.characters.split { $0 == "/" }.last


if let lastComponent = optionalLastComponent {

    //Get the string from the sub sequence by mapping the characters to [String] then reduce the array to String
    let lastComponentAsString = lastComponent.map { String($0) }.reduce("", combine: +)


    //Get the range of the last component
    if let rangeOfLastComponent = self.rangeOfString(lastComponentAsString) {
        //Get the string without its last component
        let stringWithoutLastComponent = self.substringToIndex(rangeOfLastComponent.startIndex)


        //Encode the last component
        if let lastComponentEncoded = lastComponentAsString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet()) {


        //Finally append the original string (without its last component) to the encoded part (encoded last component)
        let encodedString = stringWithoutLastComponent + lastComponentEncoded

            //Return the string (original string/encoded string)
            return encodedString
        }
    }
}

return nil;
}
}

I had this problem with device. My ads worked without problems with UnitID Test Emulator, but when testing on my device it doesn't work with message "failed to load ad: 3"

My solution was to test the app in the internal test environment of Google Play Console creating User Verifiers

Then I downloaded the app on the same device from Google Play internal testing and the ads worked for me, and it worked in production too

Use preventDefault() to stop the event of submit button and in ajax call success submit the form using submit():

$('#btnSave').click(function (e) {
    e.preventDefault(); // <------------------ stop default behaviour of button
    var element = this;    
    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            if (data.status == "Success") {
                alert("Done");
                $(element).closest("form").submit(); //<------------ submit form
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

I am using IntelliJ 2020.3.1 and the File > Other Settings... menu option has disappeared. I went to Settings in the usual way and searched for "jdk". Under Build, Execution, Deployment > Build Tools > Maven > Importing I found the the setting that will solve my specific issue:

JDK for importer.

Another way to do that is StringTokenizer. ex:-

 public static void main(String[] args) {

    String str = "This is a sample string";
    StringTokenizer st = new StringTokenizer(str," ");
    String starr[]=new String[st.countTokens()];
    while (st.hasMoreElements()) {
        starr[i++]=st.nextElement();
    }
}

SQL Server 2016 SP2 CU6 and SQL Server 2017 CU12 introduced trace flag 460 in order to return the details of truncation warnings. You can enable it at the query level or at the server level.

Query level

INSERT INTO dbo.TEST (ColumnTest)
VALUES (‘Test truncation warnings’)
OPTION (QUERYTRACEON 460);
GO

Server Level

DBCC TRACEON(460, -1);
GO

From SQL Server 2019 you can enable it at database level:

ALTER DATABASE SCOPED CONFIGURATION 
SET VERBOSE_TRUNCATION_WARNINGS = ON;

The old output message is:

Msg 8152, Level 16, State 30, Line 13
String or binary data would be truncated.
The statement has been terminated.

The new output message is:

Msg 2628, Level 16, State 1, Line 30
String or binary data would be truncated in table 'DbTest.dbo.TEST', column 'ColumnTest'. Truncated value: ‘Test truncation warnings‘'.

In a future SQL Server 2019 release, message 2628 will replace message 8152 by default.

If you want to make it clear what each of the parameters are, rather than just calling

someFunction(70, 115);

why not do the following

var width = 70, height = 115;
someFunction(width, height);

sure, it's an extra line of code, but it wins on readability.

If it outputs to stderr as well you'll want to silence that. You can do that by redirecting file descriptor 2:

# Send stdout to out.log, stderr to err.log
myprogram > out.log 2> err.log

# Send both stdout and stderr to out.log
myprogram &> out.log      # New bash syntax
myprogram > out.log 2>&1  # Older sh syntax

# Log output, hide errors.
myprogram > out.log 2> /dev/null

As a one liner:

ImageIO.write(Scalr.resize(ImageIO.read(...), 150));

IF you have data you're waiting for the server to return (item.id) and have a construct like this:

ng-style="{'background-image':'url(https://www.myImageplusitsid/{{item.id}})'}"

Make sure you add something like ng-if="item.id"

Otherwise you'll either have two requests or one faulty.

You can change style directly for scene using .root class:

.root {
    -fx-background-image: url("https://www.google.com/images/srpr/logo3w.png");
}

Add this to CSS and load it as "Uluk Biy" described in his answer.

You can use the following to convert string to int:

• CInt(String) for ints
• CDec(String) for decimals

For details refer to Type Conversion Functions (Visual Basic).

For xml formatted with attributes...

data.xml:

<building_data>
<building address="some address" lat="28.902914" lng="-71.007235" />
<building address="some address" lat="48.892342" lng="-75.0423423" />
<building address="some address" lat="58.929753" lng="-79.1236987" />
</building_data>

php code:

$reader = new XMLReader();

if (!$reader->open("data.xml")) {
    die("Failed to open 'data.xml'");
}

while($reader->read()) {
  if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == 'building') {
    $address = $reader->getAttribute('address');
    $latitude = $reader->getAttribute('lat');
    $longitude = $reader->getAttribute('lng');
}

$reader->close();

Never saw such simple way at official docs or at stack overflow, but i was amazed when found this:

# jinja2.__version__ == 2.8
from jinja2 import Template

def calcName(n, i):
    return ' '.join([n] * i)

template = Template("Hello {{ calcName('Gandalf', 2) }}")

template.render(calcName=calcName)
# or
template.render({'calcName': calcName})

In a Object Relational Mapping context, every object needs to have a unique identifier. You use the @Id annotation to specify the primary key of an entity.

The @GeneratedValue annotation is used to specify how the primary key should be generated. In your example you are using an Identity strategy which

Indicates that the persistence provider must assign primary keys for the entity using a database identity column.

There are other strategies, you can see more here.

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

You can create an autofield. Here is the documentation for the same

Please remember Django won't allow to have more than one AutoField in a model, In your model you already have one for your primary key (which is default). So you'll have to override model's save method and will probably fetch the last inserted record from the table and accordingly increment the counter and add the new record.

Please make that code thread safe because in case of multiple requests you might end up trying to insert same value for different new records.

Yes this is happening because you are accessing mi variable from within your anonymous inner class, what happens deep inside is that another copy of your variable is created and will be use inside the anonymous inner class, so for data consistency the compiler will try restrict you from changing the value of mi so that's why its telling you to set it to final.

The cross-platform way:

import time
import sys
for i in range(1,6):
    sys.stdout.write('\r\a{i}'.format(i=i))
    sys.stdout.flush()
    time.sleep(1)
sys.stdout.write('\n')

By default, Homebrew installs packages to your /usr/local. Macport commands require sudo to install and upgrade (similar to apt-get in Ubuntu).

For more detail:

This site suggests using Hombrew: http://deephill.com/macports-vs-homebrew/

whereas this site lists the advantages of using Macports: http://arstechnica.com/civis/viewtopic.php?f=19&t=1207907

I also switched from Ubuntu recently, and I enjoy using homebrew (it's simple and easy to use!), but if you feel attached to using sudo, Macports might be the better way to go!

Both functions use the os.path.split(path) function to split the pathname path into a pair; (head, tail).

The os.path.dirname(path) function returns the head of the path.

E.g.: The dirname of '/foo/bar/item' is '/foo/bar'.

The os.path.basename(path) function returns the tail of the path.

E.g.: The basename of '/foo/bar/item' returns 'item'

From: http://docs.python.org/2/library/os.path.html#os.path.basename

I had this error when I used a launch configuration that had an invalid classpath. In my case, I had a project that initially used Maven and thus a launch configuration had a Maven classpath element in it. I had later changed the project to use Gradle and removed the Maven classpath from the project's classpath, but the launch configuration still used it. I got this error trying to run it. Cleaning and rebuilding the project did not resolve this error. Instead, edit the launch configuration, remove the project classpath element, then add the project back to the User Entries in the classpath.

I never figured out the root of the problem however I was able to fix this problem. I deleted the Google Chrome app cache folder which solved the problem.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

VS2015: Updated the NuGet and worked.

Try using ReadSettings:

from readsettings import ReadSettings
data = ReadSettings("settings.json") # Load or create any json, yml, yaml or toml file
data["name"] = "value" # Set "name" to "value"
data["name"] # Returns: "value"

In xml file, put imeOptions="actionSearch" and inputType="text", maxLines="1":

<EditText
    android:id="@+id/search_box"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:maxLines="1" />

You can do this using the Class.cast() method, which dynamically casts the supplied parameter to the type of the class instance you have. To get the class instance of a particular field, you use the getType() method on the field in question. I've given an example below, but note that it omits all error handling and shouldn't be used unmodified.

public class Test {

    public String var1;
    public Integer var2;
}

public class Main {

    public static void main(String[] args) throws Exception {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("var1", "test");
        map.put("var2", 1);

        Test t = new Test();

        for (Map.Entry<String, Object> entry : map.entrySet()) {
            Field f = Test.class.getField(entry.getKey());

            f.set(t, f.getType().cast(entry.getValue()));
        }

        System.out.println(t.var1);
        System.out.println(t.var2);
    }
}

In Eclipse, right click on your project, go to Maven> Update projetc. Wait and the error will disappear. This is already configured correctly the version of Java for this project.

sed (and its ilk) are contained within several packages of Unix commands.

• Cygwin works but is gigantic.
• UnxUtils is much slimmer.
• GnuWin32 is another port that works.
• Another alternative is AT&T Research's UWIN system.
• MSYS from MinGw is yet another option.
• Windows Subsystem for Linux is a most "native" option, but it's not installed on Windows by default; it has sed, grep etc. out of the box, though.
• https://github.com/mbuilov/sed-windows offers recent 4.3 and 4.4 versions, which support -z option unlike listed upper ports

If you don't want to install anything and your system ain't a Windows Server one, then you could use a scripting language (VBScript e.g.) for that. Below is a gross, off-the-cuff stab at it. Your command line would look like

cscript //NoLogo sed.vbs s/(oldpat)/(newpat)/ < inpfile.txt > outfile.txt

where oldpat and newpat are Microsoft vbscript regex patterns. Obviously I've only implemented the substitute command and assumed some things, but you could flesh it out to be smarter and understand more of the sed command-line.

Dim pat, patparts, rxp, inp
pat = WScript.Arguments(0)
patparts = Split(pat,"/")
Set rxp = new RegExp
rxp.Global = True
rxp.Multiline = False
rxp.Pattern = patparts(1)
Do While Not WScript.StdIn.AtEndOfStream
  inp = WScript.StdIn.ReadLine()
  WScript.Echo rxp.Replace(inp, patparts(2))
Loop

For me, only catching the mouseenter event was a bit buggy, and the tooltip was not showing/hiding properly. I had to write this, and it is now working perfectly:

$(document).on('mouseenter','[rel=tooltip]', function(){
    $(this).tooltip('show');
});

$(document).on('mouseleave','[rel=tooltip]', function(){

TextView comes with 4 compound drawables, one for each of left, top, right and bottom.

In your case, you do not need the LinearLayout and ImageView at all. Just add android:drawableLeft="@drawable/up_count_big" to your TextView.

See TextView#setCompoundDrawablesWithIntrinsicBounds for more info.

After enabling "SQL Server and Windows Authentication mode"(check above answers on how to), navigate to the following.

1. Computer Mangement(in Start Menu)
2. Services And Applications
3. SQL Server Configuration Manager
4. SQL Server Network Configuration
5. Protocols for MSSQLSERVER
6. Right click on TCP/IP and Enable it.

Finally restart the SQL Server.

I've tried a select statement now with a PreparedStatement, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.

Anyway, the reason for my sql SELECTs being so slow was another one. In the WHERE clause I always used the operator LIKE, when all I wanted to do was finding an exact match. As I've found out LIKE searches for a pattern and therefore is pretty slow.

I'm using the operator = now and it's much faster.

Think of variables (e.g. foo) of reference types (e.g. List<T>) as holding object identifiers of the form "Object #24601". Suppose the statement foo = new List<int> {1,5,7,9}; causes foo to hold "Object #24601" (a list with four items). Then calling foo.Length will ask Object #24601 for its length, and it will respond 4, so foo.Length will equal 4.

If foo is passed to a method without using ref, that method might make changes to Object #24601. As a consequence of such changes, foo.Length might no longer equal 4. The method itself, however, will be unable to change foo, which will continue to hold "Object #24601".

Passing foo as a ref parameter will allow the called method to make changes not just to Object #24601, but also to foo itself. The method might create a new Object #8675309 and store a reference to that in foo. If it does so, foo would no longer hold "Object #24601", but instead "Object #8675309".

In practice, reference-type variables don't hold strings of the form "Object #8675309"; they don't even hold anything that can meaningfully converted into a number. Even though each reference-type variable will hold some bit pattern, there is no fixed relationship between the bit patterns stored in such variables and the objects they identify. There is no way code could extract information from an object or a reference to it, and later determine whether another reference identified the same object, unless the code either held or knew of a reference that identified the original object.

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

Alternatively you can use:

this.element=$(id)[0];

This is checked and works in all browsers.

None of this is a creation time. Most Unix filesystems don't support creation timestamps.

You can apply custom date time format using ToString like:

DateTime.Now.Date.ToString("MM/dd/yyyy");

Further reading on DateTime.ToString formats pattern can be found here and here.

Edit: After your question edit, Just like what other suggested you should apply the date format at your view:

model.Returndate = DateTime.Now.Date;

@Html.EditorFor(model => model.Returndate.Date.ToString("MM/dd/yyyy"))

Following width worked well in HTML5: -

    <th style="min-width:60px">Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

All answers copy lists, or create a new list, or use slow functions, or are just painfully slow.

To my understanding, this is the fastest and cheapest method I know (also, backed by a very experienced programmer specialized on real-time physics optimization).

// Duplicates will be noticed after a sort O(nLogn)
list.Sort();

// Store the current and last items. Current item declaration is not really needed, and probably optimized by the compiler, but in case it's not...
int lastItem = -1;
int currItem = -1;

int size = list.Count;

// Store the index pointing to the last item we want to keep in the list
int last = size - 1;

// Travel the items from last to first O(n)
for (int i = last; i >= 0; --i)
{
    currItem = list[i];

    // If this item was the same as the previous one, we don't want it
    if (currItem == lastItem)
    {
        // Overwrite last in current place. It is a swap but we don't need the last
       list[i] = list[last];

        // Reduce the last index, we don't want that one anymore
        last--;
    }

    // A new item, we store it and continue
    else
        lastItem = currItem;
}

// We now have an unsorted list with the duplicates at the end.

// Remove the last items just once
list.RemoveRange(last + 1, size - last - 1);

// Sort again O(n logn)
list.Sort();

Final cost is:

nlogn + n + nlogn = n + 2nlogn = O(nlogn) which is pretty nice.

Note about RemoveRange: Since we cannot set the count of the list and avoid using the Remove funcions, I don't know exactly the speed of this operation but I guess it is the fastest way.

This might help

If you are looking for a JavaScript solution, here's my gist:

https://gist.github.com/sillicon/4abcd9079a7d29cbb53ebee547b55fba

The basic idea is the same, take the screen shot first, then crop it. However, my solution will not require other libraries, just pure WebDriver API code. However, the side effect is that it may increase the load of your testing browser.

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.

Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.

You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.

You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

fmod(x, y) is the function you use.

Hiberante supports the feature of lazy initialization for both entities and collections. Hibernate engine loads only those objects that we are querying for does not other entites or collections.

lazy="false" by default loading initialization mention for the only child is lazy.in case of true that is parent is loading does not support child

Probably, the simplest solution on the ES6 age.

Adding following one liner directive makes HTML 'autofocus' attribute effective on Angular.js.

.directive('autofocus', ($timeout) => ({link: (_, e) => $timeout(() => e[0].focus())}))

Now, you can just use HTML5 autofocus syntax like:

<input type="text" autofocus>

The only solution I can think of is to install VMWare or any other VT then install OSX on a VM.

It works pretty good for testing.

JS ist browser-based, PHP is server-based. You have to generate some browser-based request/signal to get the data from the JS into the PHP. Take a look into Ajax.

One way is to leave a raw_input() at the end so the script waits for you to press enter before it terminates.

The advantage of using raw_input() instead of msvcrt.* stuff is that the former is a part of standard Python (i.e. absolutely cross-platform). This also means that the script window will be alive after double-clicking on the script file icon, without the need to do

cmd /K python <script>

Here is what I did.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

You can install packages listed in a text file called requirements file. For example, if you have a file called req.txt containing the following text:

Django==1.4
South==0.7.3

and you issue at the command line:

pip install -r req.txt

pip will install packages listed in the file at the specific revisions.

.  = This location
.. = Up a directory

So, ./foo.html is just foo.html. And it is optional, but may have relevance if a script generated the path (relevance to the script that is, not how the reference works).

This can also be done in the GUI:

1. Under the table "Person", right click Indexes
2. Click/hover New Index
3. Click Non-Clustered Index...

4. A default Index name will be given but you may want to change it.
5. Check Unique checkbox
6. Click Add... button

7. Check the columns you want included

8. Click OK in each window.

http sends/receives data as strings... this is just the way things are. You are looking to parse the string as json.

You have a line break <br> in-between the second and third images in your markup. Get rid of that, and it'll show inline.

I am not sure what caused this but it went all well once I changed the path name from Lib into lib and I was finally able to make it work.

Euler path is a graph using every edge(NOTE) of the graph exactly once. Euler circuit is a euler path that returns to it starting point after covering all edges.

While hamilton path is a graph that covers all vertex(NOTE) exactly once. When this path returns to its starting point than this path is called hamilton circuit.

You're getting into looping most likely due to these rules:

RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

Just comment it out and try again in a new browser.

Perhaps you were looking at the space complexity? That is O(n). The other complexities are as expected on the hash table entry. The search complexity approaches O(1) as the number of buckets increases. If at the worst case you have only one bucket in the hash table, then the search complexity is O(n).

Edit in response to comment I don't think it is correct to say O(1) is the average case. It really is (as the wikipedia page says) O(1+n/k) where K is the hash table size. If K is large enough, then the result is effectively O(1). But suppose K is 10 and N is 100. In that case each bucket will have on average 10 entries, so the search time is definitely not O(1); it is a linear search through up to 10 entries.

For future purposes, this may help too:

It's ok to use setState in useEffect you just need to have attention as described already to not create a loop.

But it's not the only problem that may occur. See below:

Imagine that you have a component Comp that receives props from parent and according to a props change you want to set Comp's state. For some reason, you need to change for each prop in a different useEffect:

DO NOT DO THIS

useEffect(() => {
  setState({ ...state, a: props.a });
}, [props.a]);

useEffect(() => {
  setState({ ...state, b: props.b });
}, [props.b]);

It may never change the state of a as you can see in this example: https://codesandbox.io/s/confident-lederberg-dtx7w

The reason why this happen in this example it's because both useEffects run in the same react cycle when you change both prop.a and prop.b so the value of {...state} when you do setState are exactly the same in both useEffect because they are in the same context. When you run the second setState it will replace the first setState.

DO THIS INSTEAD

The solution for this problem is basically call setState like this:

useEffect(() => {
  setState(state => ({ ...state, a: props.a }));
}, [props.a]);

useEffect(() => {
  setState(state => ({ ...state, b: props.b }));
}, [props.b]);

Check the solution here: https://codesandbox.io/s/mutable-surf-nynlx

Now, you always receive the most updated and correct value of the state when you proceed with the setState.

I hope this helps someone!

If you are using Fish shell, you can leverage the string functions:

git branch -d (git branch -l "<your pattern>" | string trim)

This is not much different from the Powershell options in some of the other answers.

If you run SHOW VARIABLES from a mysql console you can look for basedir.

When I run the following:

mysql> SHOW VARIABLES WHERE `Variable_name` = 'basedir';

on my system I get /usr/local/mysql as the Value returned. (I am not using MAMP - I installed MySQL with homebrew.

mysqldon my machine is in /usr/local/mysql/bin so the basedir is where most everything will be installed to.

Also util:

mysql> SHOW VARIABLES WHERE `Variable_name` = 'datadir'; 

To find where the DBs are stored.

An updated answer for C++11:

Use the sleep_for and sleep_until functions:

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread; // sleep_for, sleep_until
    using namespace std::chrono; // nanoseconds, system_clock, seconds

    sleep_for(nanoseconds(10));
    sleep_until(system_clock::now() + seconds(1));
}

With these functions there's no longer a need to continually add new functions for better resolution: sleep, usleep, nanosleep, etc. sleep_for and sleep_until are template functions that can accept values of any resolution via chrono types; hours, seconds, femtoseconds, etc.

In C++14 you can further simplify the code with the literal suffixes for nanoseconds and seconds:

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread;     // sleep_for, sleep_until
    using namespace std::chrono_literals; // ns, us, ms, s, h, etc.
    using std::chrono::system_clock;

    sleep_for(10ns);
    sleep_until(system_clock::now() + 1s);
}

Note that the actual duration of a sleep depends on the implementation: You can ask to sleep for 10 nanoseconds, but an implementation might end up sleeping for a millisecond instead, if that's the shortest it can do.

Looks like you haven't upgraded PHP modules, they are not compatible.

Check extension_dir directive in your php.ini. It should point to folder with 5.2 modules.

Create and open a phpinfo file and search for extension_dir to find the path.

Since you did upgrade, there is a chance that you are using old php.ini that is pointing to 5.1 modules

Just use a UIButton, its already built in. Turn off all the extra button features and you have a label that you can set edge instets on.

let button = UIButton()
button.contentEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
button.setTitle("title", for: .normal)
button.tintColor = .white // this will be the textColor
button.isUserInteractionEnabled = false

The answer by mpen is incredibly thorough, but, unfortunately, the provided benchmark has a very important and detrimental oversight.

Because every byte in needles and haystacks is completely random, the probability that a needle-haystack pair will differ on the very first byte is 99.609375%, which means that, on average, about 99609 of the 100000 pairs will differ on the very first byte. In other words, the benchmark is heavily biased towards startswith implementations which check the first byte explicitly, as strncmp_startswith2 does.

If the test-generating loop is instead implemented as follows:

echo 'generating tests';
for($i = 0; $i < 100000; ++$i) {
    if($i % 2500 === 0) echo '.';

    $haystack_length = random_int(1, 7000);
    $haystack = random_bytes($haystack_length);

    $needle_length = random_int(1, 3000);
    $overlap_length = min(random_int(0, $needle_length), $haystack_length);
    $needle = ($needle_length > $overlap_length) ?
        substr($haystack, 0, $overlap_length) . random_bytes($needle_length - $overlap_length) :
        substr($haystack, 0, $needle_length);

    $test_cases[] = [$haystack, $needle];
}
echo " done!<br />";

the benchmark results tell a slightly different story:

strncmp_startswith: 223.0 ms
substr_startswith: 228.0 ms
substr_compare_startswith: 238.0 ms
strncmp_startswith2: 253.0 ms
strpos_startswith: 349.0 ms
preg_match_startswith: 20,828.7 ms

Of course, this benchmark may still not be perfectly unbiased, but it tests the efficiency of the algorithms when given partially matching needles as well.

First check if mingw32-make is installed on your system. Use mingw32-make.exe command in windows terminal or cmd to check, else install the package mingw32-make-bin.

then go to bin directory default ( C:\MinGW\bin) create new file make.bat

@echo off
"%~dp0mingw32-make.exe" %*

add the above content and save it

set the env variable in powershell

$Env:CC="gcc"

then compile the file

make hello

where hello.c is the name of source code

You aren't specifying the "height" of your html. When you're assigning a percentage in an element (i.e. divs) the css compiler needs to know the size of the parent element. If you don't assign that, you should see divs without height.

The most common solution is to set the following property in css:

html{
    height: 100%;
    margin: 0;
    padding: 0;
}

You are saying to the html tag (html is the parent of all the html elements) "Take all the height in the HTML document"

I hope I helped you. Cheers

I know some people will hate me, but I've found display:table-cell to help in this cases.

It is really cleaner.

The following code will negate the enter key from being used to submit a form, but will still allow you to use the enter key in a textarea. You can edit it further depending on your needs.

<script type="text/javascript">
        function stopRKey(evt) {
          var evt = (evt) ? evt : ((event) ? event : null);
          var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
          if ((evt.keyCode == 13) && ((node.type=="text") || (node.type=="radio") || (node.type=="checkbox")) )  {return false;}
        }

        document.onkeypress = stopRKey;
</script> 

You will need to use the slugify function.

>>> from django.template.defaultfilters import slugify
>>> slugify("b b b b")
u'b-b-b-b'
>>>

You can call slugify automatically by overriding the save method:

class Test(models.Model):
    q = models.CharField(max_length=30)
    s = models.SlugField()
    
    def save(self, *args, **kwargs):
        self.s = slugify(self.q)
        super(Test, self).save(*args, **kwargs)

Be aware that the above will cause your URL to change when the q field is edited, which can cause broken links. It may be preferable to generate the slug only once when you create a new object:

class Test(models.Model):
    q = models.CharField(max_length=30)
    s = models.SlugField()
    
    def save(self, *args, **kwargs):
        if not self.id:
            # Newly created object, so set slug
            self.s = slugify(self.q)

        super(Test, self).save(*args, **kwargs)

You can use Batch update but queries must be action(i.e. insert,update and delete) queries

Statement s = c.createStatement();
String s1 = "update emp set name='abc' where salary=984";
String s2 = "insert into emp values ('Osama',1420)";  
s.addBatch(s1);
s.addBatch(s2);     
s.executeBatch();

First, attempt to pull from the same refspec that you are trying to push to.

If this does not work, you can force a git push by using git push -f <repo> <refspec>, but use caution: this method can cause references to be deleted on the remote repository.

 >>> sorted(['Some', 'words', 'sort', 'differently'], key=lambda word: word.lower())

Actually, above codes can be:

>>> sorted(['Some','words','sort','differently'],key=str.lower)

According to https://docs.python.org/2/library/functions.html?highlight=sorted#sorted, key specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly).

If you want a HTML only solution, we can just use the pre tag. It defines "preformatted text" which means that it does not format word-wrapping. Here is a quick example to explain:

div {
    width: 200px;
    height: 200px;
    padding: 20px;
    background: #adf;
}
pre {
    width: 200px;
    height: 200px;
    padding: 20px;
    font: inherit;
    background: #fda;
}

<div>Look at this, this text is very neat, isn't it? But it's not quite what we want, though, is it? This text shouldn't be here! It should be all the way over there! What can we do?</div>
<pre>The pre tag has come to the rescue! Yay! However, we apologise in advance for any horizontal scrollbars that may be caused. If you need support, please raise a support ticket.</pre>

JavaScript has Maps, that provide O(1) insertion and lookup time. Therefore this can be solved in O(n) (and not O(n²) as all the other answers do). For that, it is necessary to generate a unique primitive (string / number) key for each object. One could JSON.stringify, but that's quite error prone as the order of elements could influence equality:

 JSON.stringify({ a: 1, b: 2 }) !== JSON.stringify({ b: 2, a: 1 })

Therefore, I'd take a delimiter that does not appear in any of the values and compose a string manually:

const toHash = value => value.value + "@" + value.display;

Then a Map gets created. When an element exists already in the Map, it gets removed, otherwise it gets added. Therefore only the elements that are included odd times (meaning only once) remain. This will only work if the elements are unique in each array:

const entries = new Map();

for(const el of [...firstArray, ...secondArray]) {
  const key = toHash(el);
  if(entries.has(key)) {
    entries.delete(key);
  } else {
    entries.set(key, el);
  }
}

const result = [...entries.values()];

const firstArray = [_x000D_

I ended up doing the following and it works:

return DatabaseContext.Applications
     .Include("Children.ChildRelationshipType");

use

range(count)

int and float are not iterable

DISCLAIMER: The below solution does not preserve trailing tabs.

If you know the exact number of lines in the text file, try the following method:

@ECHO OFF
SET origfile=original file
SET tempfile=temporary file
SET insertbefore=4
SET totallines=200
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /P L=
  IF %%i==%insertbefore% ECHO(
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%
COPY /Y %tempfile% %origfile% >NUL
DEL %tempfile%

The loop reads lines from the original file one by one and outputs them. The output is redirected to a temporary file. When a certain line is reached, an empty line is output before it.

After finishing, the original file is deleted and the temporary one gets assigned the original name.

UPDATE

If the number of lines is unknown beforehand, you can use the following method to obtain it:

FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C

(This line simply replaces the SET totallines=200 line in the above script.)

The method has one tiny flaw: if the file ends with an empty line, the result will be the actual number of lines minus one. If you need a workaround (or just want to play safe), you can use the method described in this answer.

If you manage the flow of adding to back stack every transaction, then you can do something like this in order to show the previous fragment when the user presses back button (you could map the home button too).

@Override
public void onBackPressed() {
    if (getFragmentManager().getBackStackEntryCount() > 0)
        getFragmentManager().popBackStack();
    else
        super.onBackPressed();
}

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

In case anyone's interested, here's my solution to the problem. It works completely independently of the Draggable objects, by using events on the Droppable object instead. It works quite well:

$(function() {
    $(".draggable").draggable({
        opacity: .4,
        create: function(){$(this).data('position',$(this).position())},
        cursor:'move',
        start:function(){$(this).stop(true,true)}
    });

    $('.active').droppable({
        over: function(event, ui) {
            $(ui.helper).unbind("mouseup");
        },
        drop:function(event, ui){
            snapToMiddle(ui.draggable,$(this));
        },
        out:function(event, ui){
            $(ui.helper).mouseup(function() {
                snapToStart(ui.draggable,$(this)); 
            });
        }
    });
}); 

function snapToMiddle(dragger, target){
    var topMove = target.position().top - dragger.data('position').top + (target.outerHeight(true) - dragger.outerHeight(true)) / 2;
    var leftMove= target.position().left - dragger.data('position').left + (target.outerWidth(true) - dragger.outerWidth(true)) / 2;
    dragger.animate({top:topMove,left:leftMove},{duration:600,easing:'easeOutBack'});
}
function snapToStart(dragger, target){
    dragger.animate({top:0,left:0},{duration:600,easing:'easeOutBack'});
}

Yes there is a difference in the performance of both: jQuery('#id').show() is slower than jQuery('#id').css("display","block") as in former case extra work is to be done for retrieving the initial state from the jquery cache as display is not a binary attribute it can be inline,block,none,table, etc. similar is the case with hide() method.

See: http://jsperf.com/show-vs-addclass

Whilst the solutions proposed appear to work for simple examples, doing this in general is a bad idea. A number might not be exactly an integer but when you try to format it, it's close enough to an integer that you get 1.000000. This can happen if you do a calculation that in theory should give exactly 1, but in practice gives a number very close to but not exactly equal to one due to rounding errors.

Instead, format it first and if your string ends in a period followed by zeros then strip them. There are also some formats that you can use that strip trailing zeros automatically. This might be good enough for your purpose.

double d = 1.0002;
Console.WriteLine(d.ToString("0.##"));
d = 1.02;
Console.WriteLine(d.ToString("0.##"));

Output:

1
1.02

Recently I've been in a trouble with Visual Studio 2012 with same error description: "The process cannot access the file because it is being used by another process..."

To fix this first of all you need to understand the application which still use it. I've shutdown all processes like "MSBuild" and "MSBuild host". But this is not enough. If you have installed "Code Contracts" and turned on then it sometimes takes your DLLs for checking and hanging up on this operation.

So, you need to stop all processes of "CCCheck.exe" and that's all.

Finally, to understand that process is using your DLL you always may try to just Delete "obj" folder in your File Manager and this operation will fail, you may see the "Message Window" with description of the hanging operation. Also, as a variant, you can try to use "Sys Internals Suite" application.

Presenting the Cadillac of Diffs as an SP. See within for the basic template that was based on answer by @erikkallen. It supports

• Duplicate row sensing (most other answers here do not)
• Sort results by argument
• Limit to specific columns
• Ignore columns (e.g. ModifiedUtc)
• Cross database tables names
• Temp tables (use as workaround to diff views)

Usage:

exec Common.usp_DiffTableRows '#t1', '#t2';

exec Common.usp_DiffTableRows 
    @pTable0          = 'ydb.ysh.table1',
    @pTable1          = 'xdb.xsh.table2',
    @pOrderByCsvOpt   = null,  -- Order the results
    @pOnlyCsvOpt      = null,  -- Only compare these columns
    @pIgnoreCsvOpt    = null;  -- Ignore these columns (ignored if @pOnlyCsvOpt is specified)

Code:

alter proc [Common].[usp_DiffTableRows]    
    @pTable0          varchar(300),
    @pTable1          varchar(300),
    @pOrderByCsvOpt   nvarchar(1000) = null,  -- Order the Results
    @pOnlyCsvOpt      nvarchar(4000) = null,  -- Only compare these columns
    @pIgnoreCsvOpt    nvarchar(4000) = null,  -- Ignore these columns (ignored if @pOnlyCsvOpt is specified)

Underscore's _.isEqual(object, other) function seems to work well for arrays. The order of items in the array matter when it checks for equality. See http://underscorejs.org/#isEqual.

I had the same problem, when I saw that my Node.js installation is outdated.

These few lines will handle everything (for Ubuntu):

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

After this node -v will return you the latest available version.

Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.

And the verification can be easily made with the following script contained in the blog post before:

DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)

ytd2 is a fully functional YouTube video downloader. Check out its source code if you want to see how it's done.

Alternatively, you can also call an external process like youtube-dl to do the job. This is probably the easiest solution but it isn't in "pure" Java.

Use import scala.collection.mutable.MutableList or similar if you really need mutation.

import scala.collection.mutable.MutableList
val x = MutableList(1, 2, 3, 4, 5)
x += 6 // MutableList(1, 2, 3, 4, 5, 6)
x ++= MutableList(7, 8, 9) // MutableList(1, 2, 3, 4, 5, 6, 7, 8, 9)

Use Dialog for simple yes or no dialogs.

When you need more complex views in which you need get hold of the lifecycle such as oncreate, request permissions, any life cycle override I would use a dialog fragment. Thus you separate the permissions and any other code the dialog needs to operate without having to communicate with the calling activity.

I just had the same problem: You have to unserialize the data on the php side.

Add to the beginning of your php file (Attention this short version would replace all other post variables):

parse_str($_POST["data"], $_POST);

.jar file will be automatically generate when u compile/run your application.

You can find your class.jar file from root_folder/app/build/intermediates/bundles/debug

Even after you delete the file(s) and then commit, you will still have those files in history. To delete those, consider using BFG Repo-Cleaner. It is an alternative to git-filter-branch.

With the unobtrusive way:

• You don't have to call the validate() method.
• You specify requirements using data attributes (data-val, data-val-required, etc.)

Jquery Validate Example:

<input type="text" name="email" class="required">
<script>
        $(function () {
            $("form").validate();
        });
</script>

Jquery Validate Unobtrusive Example:

<input type="text" name="email" data-val="true" 
data-val-required="This field is required.">  

<div class="validation-summary-valid" data-valmsg-summary="true">
    <ul><li style="display:none"></li></ul>
</div>

The strings that contain \xF0 are simply characters encoded as multiple bytes using UTF-8.

Although your collation is set to utf8_general_ci, I suspect that the character encoding of the database, table or even column may be different. They are independent settings. Try:

ALTER TABLE database.table MODIFY COLUMN col VARCHAR(255)  
    CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

Substitute whatever your actual data type is for VARCHAR(255)

The excellent book "Algorithm Design Manual" by Skienna contains a huge repository of Algorithms and Data structure.

For tons of problems, data structures and algorithm are described, compared, and discusses the practical usage. The author also provides references to implementations and the original research papers.

The book is great to have it on your desk if you search the best data structure for your problem to solve. It is also very helpful for interview preparation.

Another great resource is the NIST Dictionary of Data structures and algorithms.

Quite simple, with a * wildcard.

cp -r Folder1/* Folder2/

But according to your example recursion is not needed so the following will suffice:

cp Folder1/* Folder2/

EDIT:

Or skip the mkdir Folder2 part and just run:

cp -r Folder1 Folder2

As of PHP 5.6 @$filePath will not work in CURLOPT_POSTFIELDS without CURLOPT_SAFE_UPLOAD being set and it is completely removed in PHP 7. You will need to use a CurlFile object, RFC here.

$fields = [
    'name' => new \CurlFile($filePath, 'image/png', 'filename.png')
];
curl_setopt($resource, CURLOPT_POSTFIELDS, $fields);

You could also use innerhtml to get the value within the tag....

Additionally there is a possibility to set a list of properties that will get transitioned by setting the property transition-property: width, height;, more details here

just adding this snipped in the build.gradle also works fine

android {
   compileSdkVersion 22
   buildToolsVersion "23.0.0"

     defaultConfig {
         minSdkVersion 14 //lower than 14 doesn't support multidex
         targetSdkVersion 22

         **// Enabling multidex support.
         **multiDexEnabled true****
     }
}

Wrap the label and input in another div with a defined height. This may not work in IE versions lower than 8.

position:absolute; 
top:0; bottom:0; left:0; right:0;
margin:auto;

You can also add new json objects into your json, using the extend function,

var newJson = $.extend({}, {my:"json"}, {other:"json"});
// result -> {my: "json", other: "json"}

A very good option for the extend function is the recursive merge. Just add the true value as the first parameter (read the documentation for more options). Example,

var newJson = $.extend(true, {}, {
    my:"json",
    nestedJson: {a1:1, a2:2}
}, {
    other:"json",
    nestedJson: {b1:1, b2:2}
});
// result -> {my: "json", other: "json", nestedJson: {a1:1, a2:2, b1:1, b2:2}}

SELECT COLUMN_NAME, IS_NULLABLE, DATA_TYPE, CHARACTER_MAXIMUM_LENGTH FROM information_schema.columns WHERE table_name = '<name_of_table_or_view>'

Run SELECT * in the above statement to see what information_schema.columns returns.

For any wanderer that comes across this in the future. If your application and database are on different machines and you are getting the above error especially when using TransactionScope, enable Network DTC access. Steps to do this are:

1. Add firewall rules to allow your machines to talk to each other.
2. Ensure the distributed transaction coordinator service is running
3. Enable network dtc access. Run dcomcnfg. Go to Component sevices > My Computer > Distributed Transaction Coordinator > Local DTC. Right click properties.
4. Enable network dtc access as shown.

Important: Do not edit/change the user account and password in the DTC Logon account field, leave it as is, you will end up re-installing windows if you do.

function htmlEntities(str) {
    return String(str).replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/"/g, '&quot;');
}

So then with var unsafestring = "<oohlook&atme>"; you would use htmlEntities(unsafestring);

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

There are several parts of hibernate logging you can control based on the logger hierarchy of the hibernate package (more on logger hierarchy here).

    <!-- Log everything in hibernate -->
    <Logger name="org.hibernate" level="info" additivity="false">
      <AppenderRef ref="Console" />
    </Logger>

    <!-- Log SQL statements -->
    <Logger name="org.hibernate.SQL" level="debug" additivity="false">
      <AppenderRef ref="Console" />
      <AppenderRef ref="File" />
    </Logger>

    <!-- Log JDBC bind parameters -->
    <Logger name="org.hibernate.type.descriptor.sql" level="trace" additivity="false">
      <AppenderRef ref="Console" />
      <AppenderRef ref="File" />
    </Logger>

The above was taken from here.

Additionally you could have the property show-sql:true in your configuration file since that supersedes the logging framework settings. More on that here.

This depends a lot on what you mean by "revert".

Temporarily switch to a different commit

If you want to temporarily go back to it, fool around, then come back to where you are, all you have to do is check out the desired commit:

# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32

Or if you want to make commits while you're there, go ahead and make a new branch while you're at it:

git checkout -b old-state 0d1d7fc32

To go back to where you were, just check out the branch you were on again. (If you've made changes, as always when switching branches, you'll have to deal with them as appropriate. You could reset to throw them away; you could stash, checkout, stash pop to take them with you; you could commit them to a branch there if you want a branch there.)

Hard delete unpublished commits

If, on the other hand, you want to really get rid of everything you've done since then, there are two possibilities. One, if you haven't published any of these commits, simply reset:

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts, if you've modified things which were
# changed since the commit you reset to.

If you mess up, you've already thrown away your local changes, but you can at least get back to where you were before by resetting again.

Undo published commits with new commits

On the other hand, if you've published the work, you probably don't want to reset the branch, since that's effectively rewriting history. In that case, you could indeed revert the commits. With Git, revert has a very specific meaning: create a commit with the reverse patch to cancel it out. This way you don't rewrite any history.

# This will create three separate revert commits:
git revert a867b4af 25eee4ca 0766c053

# It also takes ranges. This will revert the last two commits:
git revert HEAD~2..HEAD

#Similarly, you can revert a range of commits using commit hashes (non inclusive of first hash):
git revert 0d1d7fc..a867b4a

# Reverting a merge commit
git revert -m 1 <merge_commit_sha>

# To get just one, you could use `rebase -i` to squash them afterwards
# Or, you could do it manually (be sure to do this at top level of the repo)
# get your index and work tree into the desired state, without changing HEAD:
git checkout 0d1d7fc32 .

# Then commit. Be sure and write a good message describing what you just did
git commit

The git-revert manpage actually covers a lot of this in its description. Another useful link is this git-scm.com section discussing git-revert.

If you decide you didn't want to revert after all, you can revert the revert (as described here) or reset back to before the revert (see the previous section).

You may also find this answer helpful in this case:
How can I move HEAD back to a previous location? (Detached head) & Undo commits

Its not that hard to replicate in javascript :-) , though it will only work for width and height the best but you can expand it as per your expectations :-)

function calcShim(element,property,expression){
    var calculated = 0;
    var freed_expression = expression.replace(/ /gi,'').replace("(","").replace(")","");
    // Remove all the ( ) and spaces 
    // Now find the parts 
    var parts = freed_expression.split(/[\*+-\/]/gi);

    var units = {
        'px':function(quantity){
            var part = 0;
            part = parseFloat(quantity,10);
            return part;
        },
        '%':function(quantity){
            var part = 0,
            parentQuantity = parseFloat(element.parent().css(property));
            part = parentQuantity * ((parseFloat(quantity,10))/100);
            return part;
        } // you can always add more units here.
    }

    for( var i = 0; i < parts.length; i++ ){
        for( var unit in units ){
            if( parts[i].indexOf(unit) != -1 ){
               // replace the expression by calculated part.
               expression = expression.replace(parts[i],units[unit](parts[i]));
               break;
            }
        }
    }
    // And now compute it. though eval is evil but in some cases its a good friend.
    // Though i wish there was math. calc
    element.css(property,eval(expression));
}

Here's how I ended up doing this:

        <div id="divform">
            <form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
                <div>Certificate 1: <input type="file" name="cert1"/></div>
                <div>Certificate 2: <input type="file" name="cert2"/></div>

                <div><input type="button" value="Upload" onclick="closeSelf();"/></div>
            </form>
        </div>
        <div  id="closelink" style="display:none">
            <a href="javascript:window.close()">Click Here to Close this Page</a>
        </div>

function closeSelf(){
    document.forms['certform'].submit();
    hide(document.getElementById('divform'));
    unHide(document.getElementById('closelink'));

}

Where hide() and unhide() set the style.display to 'none' and 'block' respectively.

Not exactly what I had in mind, but this will have to do for the time being. Works on IE, Safari, FF and Chrome.

The documentation is misleading.
I have the following code running in production

DECLARE @table TABLE (UserID varchar(100))
DECLARE @sql varchar(1000)
SET @sql = 'spSelUserIDList'
/* Will also work
   SET @sql = 'SELECT UserID FROM UserTable'
*/

INSERT INTO @table
EXEC(@sql)

SELECT * FROM @table

A null pointer is guaranteed to not compare equal to a pointer to any object. It's actual value is system dependent and may vary depending on the type. To get a null int pointer you would do

int* p = 0;

A null pointer will be returned by malloc on failure.

We can test if a pointer is null, i.e. if malloc or some other function failed simply by testing its boolean value:

if (p) {
    /* Pointer is not null */
} else {
    /* Pointer is null */
}

A void pointer can point to any type and it is up to you to handle how much memory the referenced objects consume for the purpose of dereferencing and pointer arithmetic.

Here is a PHP function that will insert a row only if all the specified columns values don't already exist in the table.

• If one of the columns differ, the row will be added.

• If the table is empty, the row will be added.

• If a row exists where all the specified columns have the specified values, the row won't be added.

  function insert_unique($table, $vars)
  {
    if (count($vars)) {
      $table = mysql_real_escape_string($table);
      $vars = array_map('mysql_real_escape_string', $vars);
  
      $req = "INSERT INTO `$table` (`". join('`, `', array_keys($vars)) ."`) ";
      $req .= "SELECT '". join("', '", $vars) ."' FROM DUAL ";
      $req .= "WHERE NOT EXISTS (SELECT 1 FROM `$table` WHERE ";
  
      foreach ($vars AS $col => $val)
        $req .= "`$col`='$val' AND ";
  
      $req = substr($req, 0, -5) . ") LIMIT 1";
  
      $res = mysql_query($req) OR die();
      return mysql_insert_id();
    }
  
    return False;
  }
  

Example usage :

<?php
insert_unique('mytable', array(
  'mycolumn1' => 'myvalue1',
  'mycolumn2' => 'myvalue2',
  'mycolumn3' => 'myvalue3'
  )
);
?>

Combining map and struct allow unmarshaling nested JSON objects where the key is dynamic. => map[string]

For example: stock.json

{
  "MU": {
    "symbol": "MU",
    "title": "micro semiconductor",
    "share": 400,
    "purchase_price": 60.5,
    "target_price": 70
  },
  "LSCC":{
    "symbol": "LSCC",
    "title": "lattice semiconductor",
    "share": 200,
    "purchase_price": 20,
    "target_price": 30
  }
}

Go application

package main

import (
    "encoding/json"
    "fmt"
    "io/ioutil"
    "log"
    "os"
)

type Stock struct {
    Symbol        string  `json:"symbol"`
    Title         string  `json:"title"`
    Share         int     `json:"share"`
    PurchasePrice float64 `json:"purchase_price"`
    TargetPrice   float64 `json:"target_price"`
}
type Account map[string]Stock

func main() {
    raw, err := ioutil.ReadFile("stock.json")
    if err != nil {
        fmt.Println(err.Error())
        os.Exit(1)
    }
    var account Account
    log.Println(account)
}

The dynamic key in the hash is handle a string, and the nested object is represented by a struct.

I had also forgotten to actually install MySQL in the first place. Following this guide helped a lot.

http://www.djangoapp.com/blog/2011/07/24/installation-of-mysql-server-on-mac-os-x-lion/

As well as adding these lines to my .profile:

export PATH="/usr/local/mysql/bin:$PATH"
alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin

I figured it out. The problem was that there were still some pages in the project that hadn't been converted to use "namespaces" as needed in a web application project. I guess I thought that it wouldn't compile if there were still any of those pages around, but if the page didn't reference anything from outside itself it didn't appear to squawk. So when it was saying that it didn't inherit from "System.Web.UI.Page" that was because it couldn't actually find the class "BasePage" at run time because the page itself was not in the WebApplication namespace. I went through all my pages one by one and made sure that they were properly added to the WebApplication namespace and now it not only compiles without issue, it also displays normally. yay!

what a trial converting from website to web application project can be!

Or this beautiful round progress bar with HTML5, CSS3 and JavaScript.

display is not an attribute - it's a CSS property. You need to access the style object for this:

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

Value cannot be null. Parameter name: source

Above error comes in situation when you are querying the collection which is null.

For demonstration below code will result in such an exception.

Console.WriteLine("Hello World");
IEnumerable<int> list = null;
list.Where(d => d ==4).FirstOrDefault();

Here is the output of the above code.

Hello World Run-time exception (line 11): Value cannot be null. Parameter name: source

Stack Trace:

[System.ArgumentNullException: Value cannot be null. Parameter name: source] at Program.Main(): line 11

In your case ListMetadataKor is null. Here is the fiddle if you want to play around.

In my case it was empty assets catalog, when I delete it everything was fine again.

It's nothing complicated. We cannot use getFragmentManager() here. For using Fragments inside a Fragment, we use getChildFragmentManager(). Rest will be the same.

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

You could choose to rank your data and add a ROW_NUMBER and count down to zero while iterate your dataset.

-- Get your dataset and rank your dataset by adding a new row_number
SELECT  TOP 1000 A.*, ROW_NUMBER() OVER(ORDER BY A.ID DESC) AS ROW
INTO #TEMPTABLE 
FROM DBO.TABLE AS A
WHERE STATUSID = 7;

--Find the highest number to start with
DECLARE @COUNTER INT = (SELECT MAX(ROW) FROM #TEMPTABLE);
DECLARE @ROW INT;

-- Loop true your data until you hit 0
WHILE (@COUNTER != 0)
BEGIN

    SELECT @ROW = ROW
    FROM #TEMPTABLE
    WHERE ROW = @COUNTER
    ORDER BY ROW DESC

    --DO SOMTHING COOL  

    -- SET your counter to -1
    SET @COUNTER = @ROW -1
END

DROP TABLE #TEMPTABLE

The problem could come down to which box model you're using. Are you using IE?

When IE is in quirks mode, width is the outer width of your box, which means the padding will be inside. So the total area left inside the box is 100px - 2 * 10px = 80px in which case your 100px wide <hr> will not look right.

If you're in standards mode, width is the inner width of your box, and padding is added outside. So the total width of the box is 100px + 2 * 10px = 120px leaving exactly 100px inside the box for your <hr>.

To solve it, either adjust your CSS values for IE. (Check in Firefox to see if it looks okay there). Or even better, set a document type to kick the browser into strict mode - where also IE follows the standard box model.

Edit: Warning! This answer worked on my XAMPP OsX environment, but when I deployed it to AWS EC2 it did NOT prevent the upload attempt.

I was tempted to delete this answer as it is WRONG But instead I will explain what tripped me up

My file upload field is named 'upload' so I was getting "The upload failed to upload.". This message comes from this line in validation.php:

in resources/lang/en/validaton.php:

'uploaded' => 'The :attribute failed to upload.',

And this is the message displayed when the file is larger than the limit set by PHP.

I want to over-ride this message, which you normally can do by passing a third parameter $messages array to Validator::make() method.

However I can't do that as I am calling the POST from a React Component, which renders the form containing the csrf field and the upload field.

So instead, as a super-dodgy-hack, I chose to get into my view that displays the messages and replace that specific message with my friendly 'file too large' message.

Here is what works if the file to smaller than the PHP file size limit:

In case anyone else is using Laravel FormRequest class, here is what worked for me on Laravel 5.7:

This is how I set a custom error message and maximum file size:

I have an input field <input type="file" name="upload">. Note the CSRF token is required also in the form (google laravel csrf_field for what this means).

<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class Upload extends FormRequest
{
  ...
  ...
  public function rules() {
    return [
      'upload' => 'required|file|max:8192',
    ];
  }
  public function messages()
  {
    return [            
      'upload.required' => "You must use the 'Choose file' button to select which file you wish to upload",
      'upload.max' => "Maximum file size to upload is 8MB (8192 KB). If you are uploading a photo, try to reduce its resolution to make it under 8MB"
    ];
  }
}

In addition to other answers here, if the value is an integral constant, a public enum in a class or struct will work. A variable - constant or otherwise - at the root of a namespace is another option, or a static public member of a class or struct is a third option.

MyClass::eSomeConst (enum)
MyNamespace::nSomeValue 
MyStruct::nSomeValue (static) 

You can check out using branch names, for one thing.

I know there are several ways to move the HEAD around, but I'll leave it to a git expert to enumerate them.

I just wanted to suggest gitk --all -- I found it enormously helpful when starting with git.

You are probably looking for System.Guid.NewGuid().

Yes basically this is what virtualenv do , and this is what the activate command is for, from the doc here:

activate script

In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.

This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.

The activate script will also modify your shell prompt to indicate which environment is currently active.

so you should just use activate command which will do all that for you:

> \path\to\env\bin\activate.bat

Because the confusion it can generate with XML declarations. Many people agree with you, though.

An additional concern is the pain it'd generate to code everything with short tags only to find out at the end that the final hosting server has them turned off...

While I agree it's not good style to catch a raw Exception, there are ways of handling exceptions which provide for superior logging, and the ability to handle the unexpected. Since you are in an exceptional state, you are probably more interested in getting good information than in response time, so instanceof performance shouldn't be a big hit.

try{
    // IO code
} catch (Exception e){
    if(e instanceof IOException){
        // handle this exception type
    } else if (e instanceof AnotherExceptionType){
        //handle this one
    } else {
        // We didn't expect this one. What could it be? Let's log it, and let it bubble up the hierarchy.
        throw e;
    }
}

However, this doesn't take into consideration the fact that IO can also throw Errors. Errors are not Exceptions. Errors are a under a different inheritance hierarchy than Exceptions, though both share the base class Throwable. Since IO can throw Errors, you may want to go so far as to catch Throwable

try{
    // IO code
} catch (Throwable t){
    if(t instanceof Exception){
        if(t instanceof IOException){
            // handle this exception type
        } else if (t instanceof AnotherExceptionType){
            //handle this one
        } else {
            // We didn't expect this Exception. What could it be? Let's log it, and let it bubble up the hierarchy.
        }
    } else if (t instanceof Error){
        if(t instanceof IOError){
            // handle this Error
        } else if (t instanceof AnotherError){
            //handle different Error
        } else {
            // We didn't expect this Error. What could it be? Let's log it, and let it bubble up the hierarchy.
        }
    } else {
        // This should never be reached, unless you have subclassed Throwable for your own purposes.
        throw t;
    }
}

It seems that calling sudo update-alternatives --config java effects keytool. Depending on which version of Java is chosen it changes whether or not keytool is on the path. I had to chose the open JDK instead of Oracle's JDK to not get bash: /usr/bin/keytool: No such file or directory.

To show action items (action buttons) in the ActionBar of fragments where they are only needed, do this:

Lets say you want the save button to only show in the fragment where you accept input for items and not in the Fragment where you view a list of items, add this to the OnCreateOptionsMenu method of the Fragment where you view the items:

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    if (menu != null) {

        menu.findItem(R.id.action_save_item).setVisible(false);
    }
}

NOTE: For this to work, you need the onCreate() method in your Fragment (where you want to hide item button, the item view fragment in our example) and add setHasOptionsMenu(true) like this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

Might not be the best option, but it works and it's simple.

Console console = System.console();
String username = console.readLine("Username: ");
char[] password = console.readPassword("Password: ");

The second time you're referring to div2, you're not using the # id selector.

There's no element named div2.

I prefer this solution:

col = df.pop("Mid")
df.insert(0, col.name, col)

It's simpler to read and faster than other suggested answers.

def move_column_inplace(df, col, pos):
    col = df.pop(col)
    df.insert(pos, col.name, col)

Performance assessment:

For this test, the currently last column is moved to the front in each repetition. In-place methods generally perform better. While citynorman's solution can be made in-place, Ed Chum's method based on .loc and sachinnm's method based on reindex cannot.

While other methods are generic, citynorman's solution is limited to pos=0. I didn't observe any performance difference between df.loc[cols] and df[cols], which is why I didn't include some other suggestions.

I tested with python 3.6.8 and pandas 0.24.2 on a MacBook Pro (Mid 2015).

    return df

def move_to_front_chum(df, col):
    cols = list(df)
    cols.insert(0, cols.pop(cols.index(col)))
    return df.loc[:, cols]

def move_to_front_chum_inplace(df, col):
    col = df[col]
    df.drop(col.name, axis=1, inplace=True)
    df.insert(0, col.name, col)
    return df

def move_to_front_elpastor(df, col):
    cols = [col] + [ c for c in df.columns if c!=col ]
    return df[cols] # or df.loc[cols]

def move_to_front_sachinmm(df, col):
    cols = df.columns.tolist()
    cols.insert(0, cols.pop(cols.index(col)))
    df = df.reindex(columns=cols, copy=False)
    return df

def move_to_front_citynorman_inplace(df, col):
    # This approach exploits that reset_index() moves the index

file_name = open("data.json", "w")
json.dump(test_response, file_name)
file_name.close()

or use context manager, which is better:

with open("data.json", "w") as file_name:
    json.dump(test_response, file_name)

I have written a small module to do just that, called timexe:

• Its simple,small reliable code and has no dependencies
• Resolution is in milliseconds and has high precision over time
• Cron like, but not compatible (reversed order and other Improvements)
• I works in the browser too

Install:

npm install timexe

use:

var timexe = require('timexe');
//Every 30 sec
var res1=timexe(”* * * * * /30”, function() console.log(“Its time again”)});

//Every minute
var res2=timexe(”* * * * *”,function() console.log(“a minute has passed”)});

//Every 7 days
var res3=timexe(”* y/7”,function() console.log(“its the 7th day”)});

//Every Wednesdays 
var res3=timexe(”* * w3”,function() console.log(“its Wednesdays”)});

// Stop "every 30 sec. timer"
timexe.remove(res1.id);

you can achieve start/stop functionality by removing/re-adding the entry directly in the timexe job array. But its not an express function.

The above options works for Google big query file also. I exported a table data to goodle cloud storage and downloaded from there. While loading the same to sql server was facing this issue and could successfully load the file after specifying the row delimiter as

ROWTERMINATOR = '0x0a' 

Pay attention to header record as well and specify

FIRSTROW = 2

My final block for data file export from google bigquery looks like this.

BULK INSERT TABLENAME
        FROM 'C:\ETL\Data\BigQuery\In\FILENAME.csv'
        WITH
        (
         FIRSTROW = 2,
         FIELDTERMINATOR = ',',  --CSV field delimiter
         ROWTERMINATOR = '0x0a',--Files are generated with this row terminator in Google Bigquery
         TABLOCK
        )

You cannot trust g++ 4.6.3 here with 64 bit integers on a 32 bit intel platform. a/b is computed by a call to divdi3 and a%b is computed by a call to moddi3. I can even come up with an example that computes a/b and a-b*(a/b) with these calls. So I use c=a/b and a-b*c.

The div method gives a call to a function which computes the div structure, but a function call seems inefficient on platforms which have hardware support for the integral type (i.e. 64 bit integers on 64 bit intel/amd platforms).

or:

usleep(NUMBER_OF_MICRO_SECONDS);

You can use the DirectoryIterator. Example from php Manual:

<?php
$dir = new DirectoryIterator(dirname(__FILE__));
foreach ($dir as $fileinfo) {
    if (!$fileinfo->isDot()) {
        var_dump($fileinfo->getFilename());
    }
}
?>
