You can use Like

if(condition1 || condition2 || condition3 || ..........)
{       
     enter code here
}

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

Try this code. You get android device name.

public static String getDeviceName() {
    String manufacturer = Build.MANUFACTURER;
    String model = Build.MODEL;
    if (model.startsWith(manufacturer)) {
        return model;
    }
    return manufacturer + " " + model;
}

To insert the Value into the Dictionary

 Dictionary<string, string> dDS1 = new Dictionary<string, string>();//Declaration
 dDS1.Add("VEqpt", "aaaa");//adding key and value into the dictionary
 string Count = dDS1["VEqpt"];//assigning the value of dictionary key to Count variable
 dDS1["VEqpt"] = Count + "bbbb";//assigning the value to key

Since there are limited real answers I'll share this workaround. For really simple cases like your example you do it backwards...

From this

1
2
3
4
5

Replace \r\n with " />\r\n<row id=" and you'll get 90% of the way there

1" />
<row id="2" />
<row id="3" />
<row id="4" />
<row id="5

Or is a similar fashion you can hack about data with excel/spreadsheet. Just split your original data into columns and manipulate values as you require.

|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |

Obvious stuff but it may help someone doing the odd one-off hack job to save a few key strokes.

Stack

• Very fast access
• Don't have to explicitly de-allocate variables
• Space is managed efficiently by CPU, memory will not become fragmented
• Local variables only
• Limit on stack size (OS-dependent)
• Variables cannot be resized

Heap

• Variables can be accessed globally
• No limit on memory size
• (Relatively) slower access
• No guaranteed efficient use of space, memory may become fragmented over time as blocks of memory are allocated, then freed
• You must manage memory (you're in charge of allocating and freeing variables)
• Variables can be resized using realloc()

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

I'm using next approach:

Product

ProductID OrderID,...

ProductInfo

ProductID Title Name LanguageID

Language

LanguageID Name Culture,....

This is slighly more OS independent way:

# do this init somewhere
import pygame
pygame.init()
screen = pygame.display.set_mode((640, 480))
font = pygame.font.Font(pygame.font.get_default_font(), 36)

# now print the text
text_surface = font.render('Hello world', antialias=True, color=(0, 0, 0))
screen.blit(text_surface, dest=(0,0))

We can use data.table to get it quickly. First create df without factors,

df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)), stringsAsFactors=F)

Now you can use

setDT(df)
for (jj in 1:ncol(df)) set(df, i = which(df[[jj]]==""), j = jj, v = NA)

and you can convert it back to a data.frame

setDF(df)

If you only want to use data.frame and keep factors it's more difficult, you need to work with

levels(df$value)[levels(df$value)==""] <- NA

where value is the name of every column. You need to insert it in a loop.

Regardless of your environment (gcloud or not ) , you need to point your kubectl to kubeconfig. By default, kubectl expects the path as $HOME/.kube/config or point your custom path as env variable (for scripting etc ) export KUBECONFIG=/your_kubeconfig_path

Please refer :: https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/

If you don't have a kubeconfig file for your cluster, create one by referring :: https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/

It is required to find cluster's ca.crt , apiserver-kubelet-client key and cert.

Success!

I had similar problems and tried re-installing several times, but no joy. I was looking at installing individual packages from the ISO and all of the fiddling around - not happy at all.

I finally got it to "install" by simply selecting "repair" rather than "uninstall" in control panel / programs. It took quite a while to do the "repair" though. In the end it is installed and working.

This worked for me. It may help others - easier to try than many other options, anyway.

I have solved this problem by importing the following dependency. you must manually import httpclient

<dependency>
    <groupId>commons-httpclient</groupId>
    <artifactId>commons-httpclient</artifactId>
    <version>3.1</version>
    <exclusions>
        <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>*</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Sqlite can not compare on dates. we need to convert into seconds and cast it as integer.

Example

SELECT * FROM Table  
WHERE  
CAST(strftime('%s', date_field)  AS  integer) <=CAST(strftime('%s', '2015-01-01')  AS  integer) ;

The other option is to tell EF to allow the column to be null:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
        modelBuilder.Entity<SomeObject>().Property(m => m.somefield).IsOptional();            
        base.OnModelCreating(modelBuilder);
}

This code should be in the object that inherits from DbContext.

list out the installed packages in the virtualenv

step 1:

workon envname

step 2:

pip freeze

it will display the all installed packages and installed packages and versions

i see here already wrote good answers, but sometime to write the same in other form can be helpful

<div ng-app ng-controller="MyCtrl">
  <select ng-model="referral.organization" ng-options="c for c in organizations"></select>
</div>

<script type='text/javascript'>
  function MyCtrl($scope) {
    $scope.organizations = ['a', 'b', 'c', 'd', 'e'];
    $scope.referral = {
      organization: $scope.organizations[2]
    };
  }
</script>

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch class. The property on (boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.

For those of you who use SnapKit, just like me, the solution is anchoring your constraints to view.safeAreaLayoutGuide like so:

yourView.snp.makeConstraints { (make) in
    if #available(iOS 11.0, *) {
        //Bottom guide
        make.bottom.equalTo(view.safeAreaLayoutGuide.snp.bottomMargin)
        //Top guide
        make.top.equalTo(view.safeAreaLayoutGuide.snp.topMargin)
        //Leading guide
        make.leading.equalTo(view.safeAreaLayoutGuide.snp.leadingMargin)
        //Trailing guide
        make.trailing.equalTo(view.safeAreaLayoutGuide.snp.trailingMargin)

     } else {
        make.edges.equalToSuperview()
     }
}

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

// VARIABLES
$screen-xs:                                         480px;
$screen-sm:                                         768px;
$screen-md:                                         992px;
$screen-lg:                                         1200px;
$screen-xl:                                         1400px;
$screen-xxl:                                        1600px;

// QUERIES
@media screen (max-width: $screen-lg) {
    flex-basis: 25%;
}

@media screen (max-width: $screen-md) {
    flex-basis: 33.33%;
}

I used the logic in the replies by rampion and schnaader. I will summarise how I confirmed the results. I changed the numbers to binary and then used the XOR-operation. Alternatively, you can use the Hexadecimal tables: Click here!

You can try downloading the Windows binaries for pip from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pip.

For using pip to download other modules, see @Ben Burn's answer.

Show all stashes

File names only:

for i in $(git stash list --format="%gd") ; do echo "======$i======"; git stash show $i; done

Full file contents in all stashes:

for i in $(git stash list --format="%gd") ; do echo "======$i======"; git stash show -p $i; done

You will get colorized diff output that you can page with space (forward) and b (backwards), and q to close the pager for the current stash. If you would rather have it in a file then append > stashes.diff to the command.

The compiler should make them all the same in the long run. Pick a standard so that your code will be easy to read, and stick with it.

For the text after the first = and before the next =

cut -d "=" -f2 <<< "$your_str"

or

sed -e 's#.*=\(\)#\1#' <<< "$your_str"

For all text after the first = regardless of if there are multiple =

cut -d "=" -f2- <<< "$your_str"

With Android Architecture Components through the use of LiveData this can be easily implemented with any type of Adapter. You simply have to do the following steps:

1. Setup your data to return from the Room Database as LiveData as in the example below:

@Dao
public interface CustomDAO{

@Query("SELECT * FROM words_table WHERE column LIKE :searchquery")
    public LiveData<List<Word>> searchFor(String searchquery);
}

2. Create a ViewModel object to update your data live through a method that will connect your DAO and your UI

public class CustomViewModel extends AndroidViewModel {

    private final AppDatabase mAppDatabase;

    public WordListViewModel(@NonNull Application application) {
        super(application);
        this.mAppDatabase = AppDatabase.getInstance(application.getApplicationContext());
    }

    public LiveData<List<Word>> searchQuery(String query) {
        return mAppDatabase.mWordDAO().searchFor(query);
    }

}

3. Call your data from the ViewModel on the fly by passing in the query through onQueryTextListener as below:

Inside onCreateOptionsMenu set your listener as follows

searchView.setOnQueryTextListener(onQueryTextListener);

Setup your query listener somewhere in your SearchActivity class as follows

private android.support.v7.widget.SearchView.OnQueryTextListener onQueryTextListener =
            new android.support.v7.widget.SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    getResults(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    getResults(newText);
                    return true;
                }

                private void getResults(String newText) {
                    String queryText = "%" + newText + "%";
                    mCustomViewModel.searchQuery(queryText).observe(
                            SearchResultsActivity.this, new Observer<List<Word>>() {
                                @Override
                                public void onChanged(@Nullable List<Word> words) {
                                    if (words == null) return;
                                    searchAdapter.submitList(words);
                                }
                            });
                }
            };

Note: Steps (1.) and (2.) are standard AAC ViewModel and DAO implementation, the only real "magic" going on here is in the OnQueryTextListener which will update the results of your list dynamically as the query text changes.

If you need more clarification on the matter please don't hesitate to ask. I hope this helped :).

Hi another solution to this problem is to simply add the node nodejs binary folder to your PATH using the following command:

ln -s /usr/bin/nodejs /usr/bin/node

See NPM GitHub for better explanation

Short and elegant

#include <vector>
#include <string>
using namespace std;

vector<string> split(string data, string token)
{
    vector<string> output;
    size_t pos = string::npos; // size_t to avoid improbable overflow
    do
    {
        pos = data.find(token);
        output.push_back(data.substr(0, pos));
        if (string::npos != pos)
            data = data.substr(pos + token.size());
    } while (string::npos != pos);
    return output;
}

can use any string as delimiter, also can be used with binary data (std::string supports binary data, including nulls)

using:

auto a = split("this!!is!!!example!string", "!!");

output:

this
is
!example!string

Just want to share here some helpful extensions for kotlin

fun BigDecimal.isZero() = compareTo(BigDecimal.ZERO) == 0
fun BigDecimal.isOne() = compareTo(BigDecimal.ONE) == 0
fun BigDecimal.isTen() = compareTo(BigDecimal.TEN) == 0

How are you calling the start function?

This should work (new is the key)

var o = new Request(destination, stay_open);
o.start();

If you directly call it like Request.prototype.start(), this will refer to the global context (window in browsers).

Also, if this is undefined, it results in an error. The if expression does not evaluate to false.

Update: this object is not set based on declaration, but by invocation. What it means is that if you assign the function property to a variable like x = o.start and call x(), this inside start no longer refers to o. This is what happens when you do setTimeout. To make it work, do this instead:

 var o = new Request(...);
 setTimeout(function() { o.start(); }, 1000);

Use .splice to remove item from array. Using delete, indexes of the array will not be altered but the value of specific index will be undefined

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

Syntax: array.splice(start, deleteCount[, item1[, item2[, ...]]])

var people = ["Bob", "Sally", "Jack"]_x000D_
var toRemove = 'Bob';_x000D_
var index = people.indexOf(toRemove);_x000D_
if (index > -1) { //Make sure item is present in the array, without if condition, -n indexes will be considered from the end of the array._x000D_
  people.splice(index, 1);_x000D_
}_x000D_
console.log(people);

Edit:

As pointed out by justin-grant, As a rule of thumb, Never mutate this.state directly, as calling setState() afterward may replace the mutation you made. Treat this.state as if it were immutable.

The alternative is, create copies of the objects in this.state and manipulate the copies, assigning them back using setState(). Array#map, Array#filter etc. could be used.

this.setState({people: this.state.people.filter(item => item !== e.target.value);});

Although this is an old thread its the first in google search, I came up with a different answer than what came before. This will allow you to pass your criteria for what to keep within a string, whatever that criteria might be. You can put it in a function to call over and over again if you want.

declare @String VARCHAR(MAX) = '-123.  a    456-78(90)'
declare @MatchExpression VARCHAR(255) = '%[0-9]%'
declare @return varchar(max)

WHILE PatIndex(@MatchExpression, @String) > 0
    begin
    set @return = CONCAT(@return, SUBSTRING(@string,patindex(@matchexpression, @string),1))
    SET @String = Stuff(@String, PatIndex(@MatchExpression, @String), 1, '')
    end
select (@return)

Here are all the possible problems/solutions I have come across:

1. Download the cookie plugin

$.cookie is not a standard jQuery function and the plugin needs to be downloaded here. Make sure to include the appropriate <script> tag where necessary (see next).

2. Include jQuery before the cookie plugin

When including the cookie script, make sure to include jQuery FIRST, then the cookie plugin.

<script src="~/Scripts/jquery-2.0.3.js" type="text/javascript"></script>
<script src="~/Scripts/jquery_cookie.js" type="text/javascript"></script>

3. Don't include jQuery more than once

This was my problem. Make sure you aren't including jQuery more than once. If you are, it is possible that:

1. jQuery loads correctly.
2. The cookie plugin loads correctly.
3. Your second inclusion of jQuery overwrites the first and destroys the cookie plugin.

For anyone using ASP.Net MVC projects, be careful with the default javascript bundle inclusions. My second inclusion of jQuery was within one of my global layout pages under the line @Scripts.Render("~/bundles/jquery").

4. Rename the plugin file to not include ".cookie"

In some rare cases, renaming the file to something that does NOT include ".cookie" has fixed this error, apparently due to web server issues. By default, the downloaded script is titled "jquery.cookie.js" but try renaming it to something like "jquery_cookie.js" as shown above. More details on this problem are here.

Looks like you're missing the SEPARATOR keyword in the GROUP_CONCAT function.

GROUP_CONCAT(artists.artistname SEPARATOR '----')

The way you've written it, you're concatenating artists.artistname with the '----' string using the default comma separator.

Update 2017:

Use authbind

• CAP_NET_BIND_SERVICE grants trust to the binary but provides no control over per-port access.
  

• Authbind grants trust to the user/group and provides control over per-port access, and supports both IPv4 and IPv6 (IPv6 support has been added as of late).

  1. Install: apt-get install authbind

  2. Configure access to relevant ports, e.g. 80 and 443 for all users and groups:

     sudo touch /etc/authbind/byport/80
     sudo touch /etc/authbind/byport/443
     sudo chmod 777 /etc/authbind/byport/80
     sudo chmod 777 /etc/authbind/byport/443
     

  3. Execute your command via authbind
     (optionally specifying --deep or other arguments, see the man page):

     authbind --deep /path/to/binary command line args
     

     e.g.

     authbind --deep java -jar SomeServer.jar
     

As a follow-up to Joshua's fabulous (=not recommended unless you know what you do) recommendation to hack the kernel:

I've first posted it here.

Simple. With a normal or old kernel, you don't.
As pointed out by others, iptables can forward a port.
As also pointed out by others, CAP_NET_BIND_SERVICE can also do the job.
Of course CAP_NET_BIND_SERVICE will fail if you launch your program from a script, unless you set the cap on the shell interpreter, which is pointless, you could just as well run your service as root...
e.g. for Java, you have to apply it to the JAVA JVM

sudo /sbin/setcap 'cap_net_bind_service=ep' /usr/lib/jvm/java-8-openjdk/jre/bin/java

Obviously, that then means any Java program can bind system ports.
Dito for mono/.NET.

I'm also pretty sure xinetd isn't the best of ideas.
But since both methods are hacks, why not just lift the limit by lifting the restriction ?
Nobody said you have to run a normal kernel, so you can just run your own.

You just download the source for the latest kernel (or the same you currently have). Afterwards, you go to:

/usr/src/linux-<version_number>/include/net/sock.h:

There you look for this line

/* Sockets 0-1023 can't be bound to unless you are superuser */
#define PROT_SOCK       1024

and change it to

#define PROT_SOCK 0

if you don't want to have an insecure ssh situation, you alter it to this: #define PROT_SOCK 24

Generally, I'd use the lowest setting that you need, e.g 79 for http, or 24 when using SMTP on port 25.

That's already all.
Compile the kernel, and install it.
Reboot.
Finished - that stupid limit is GONE, and that also works for scripts.

Here's how you compile a kernel:

https://help.ubuntu.com/community/Kernel/Compile

# You can get the kernel-source via package linux-source, no manual download required
apt-get install linux-source fakeroot

mkdir ~/src
cd ~/src
tar xjvf /usr/src/linux-source-<version>.tar.bz2
cd linux-source-<version>

# Apply the changes to PROT_SOCK define in /include/net/sock.h

# Copy the kernel config file you are currently using
cp -vi /boot/config-`uname -r` .config

# Install ncurses libary, if you want to run menuconfig
apt-get install libncurses5 libncurses5-dev

# Run menuconfig (optional)
make menuconfig

# Define the number of threads you wanna use when compiling (should be <number CPU cores> - 1), e.g. for quad-core
export CONCURRENCY_LEVEL=3
# Now compile the custom kernel
fakeroot make-kpkg --initrd --append-to-version=custom kernel-image kernel-headers

# And wait a long long time

cd ..

In a nutshell, use iptables if you want to stay secure, compile the kernel if you want to be sure this restriction never bothers you again.

The easyest way is to change .attr() function to a javascript function .setAttribute()

$('#stop').click(function() {
    $('next')[0].setAttribute('onclick','stopMoving()');
}

Try any one of the below. These should work:

int a = Character.getNumericValue('3');
int a = Integer.parseInt(String.valueOf('3');

I think the most efficient way to do this is this is using RemoveAt:

rows.RemoveAt(rows.Count - 1)

Replace in your views (blade files) all

{{route('/')}} ----- by ----> {{url('/')}}

EDIT: Use stej's answer below. My own (partially incorrect) one is still reproduced here for reference:

You can use

Get-Variable foo -Scope Global

and trap the error that is raised when the variable doesn't exist.

Just for completeness - in SQL 2008 you would use the plus + operator to perform string concatenation.

Take a look at the MSDN reference with sample code. Starting with SQL 2012, you may wish to use the new CONCAT function.

If using Postgres, create sequence manually with name 'hibernate_sequence'. It will work.

Please check this:

$servername='localhost';
$username='root';
$password='';
$databasename='MyDb';

$connection = mysqli_connect($servername,$username,$password);

if (!$connection) {
die("Connection failed: " . $conn->connect_error);
}

/*mysqli_query($connection, "DROP DATABASE if exists MyDb;");

if(!mysqli_query($connection, "CREATE DATABASE MyDb;")){
echo "Error creating database: " . $connection->error;
}

mysqli_query($connection, "use MyDb;");
mysqli_query($connection, "DROP TABLE if exists employee;");

$table="CREATE TABLE employee (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)"; 
$value="INSERT INTO employee (firstname,lastname,email) VALUES ('john', 'steve', '[email protected]')";
if(!mysqli_query($connection, $table)){echo "Error creating table: " . $connection->error;}
if(!mysqli_query($connection, $value)){echo "Error inserting values: " . $connection->error;}*/

I'm not sure if this is the most pythonic method ... I had a list of tuples that needed sorting 1st by descending integer values and 2nd alphabetically. This required reversing the integer sort but not the alphabetical sort. Here was my solution: (on the fly in an exam btw, I was not even aware you could 'nest' sorted functions)

a = [('Al', 2),('Bill', 1),('Carol', 2), ('Abel', 3), ('Zeke', 2), ('Chris', 1)]  
b = sorted(sorted(a, key = lambda x : x[0]), key = lambda x : x[1], reverse = True)  
print(b)  
[('Abel', 3), ('Al', 2), ('Carol', 2), ('Zeke', 2), ('Bill', 1), ('Chris', 1)]

I've just written a library called jsPDF which generates PDFs using Javascript alone. It's still very young, and I'll be adding features and bug fixes soon. Also got a few ideas for workarounds in browsers that do not support Data URIs. It's licensed under a liberal MIT license.

I came across this question before I started writing it and thought I'd come back and let you know :)

Generate PDFs in Javascript

Example create a "Hello World" PDF file.

// Default export is a4 paper, portrait, using milimeters for units_x000D_
var doc = new jsPDF()_x000D_
_x000D_
doc.text('Hello world!', 10, 10)_x000D_
doc.save('a4.pdf')

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.5/jspdf.debug.js"></script>

this works nicely

width:40%; // the width of the content div
right:0;
margin-right:30%; // 1/2 the remaining space

This resizes nicely with adaptive layouts also..

CSS example would be:

.centered-div {
   position:fixed;
   background-color:#fff;
   text-align:center;
   width:40%;
   right:0;
   margin-right:30%;
}

It is worth noting that git also has a syntax for tracking "from-where-you-came"/"want-to-go-back-now" - for example, HEAD@{1} will reference the place from where you jumped to new commit location.

Basically HEAD@{} variables capture the history of HEAD movement, and you can decide to use a particular head by looking into reflogs of git using the command git reflog.

Example:

0aee51f HEAD@{0}: reset: moving to HEAD@{5}
290e035 HEAD@{1}: reset: moving to HEAD@{7}
0aee51f HEAD@{2}: reset: moving to HEAD@{3}
290e035 HEAD@{3}: reset: moving to HEAD@{3}
9e77426 HEAD@{4}: reset: moving to HEAD@{3}
290e035 HEAD@{5}: reset: moving to HEAD@{3}
0aee51f HEAD@{6}: reset: moving to HEAD@{3}
290e035 HEAD@{7}: reset: moving to HEAD@{3}
9e77426 HEAD@{8}: reset: moving to HEAD@{3}
290e035 HEAD@{9}: reset: moving to HEAD@{1}
0aee51f HEAD@{10}: reset: moving to HEAD@{4}
290e035 HEAD@{11}: reset: moving to HEAD^
9e77426 HEAD@{12}: reset: moving to HEAD^
eb48179 HEAD@{13}: reset: moving to HEAD~
f916d93 HEAD@{14}: reset: moving to HEAD~
0aee51f HEAD@{15}: reset: moving to HEAD@{5}
f19fd9b HEAD@{16}: reset: moving to HEAD~1
290e035 HEAD@{17}: reset: moving to HEAD~2
eb48179 HEAD@{18}: reset: moving to HEAD~2
0aee51f HEAD@{19}: reset: moving to HEAD@{5}
eb48179 HEAD@{20}: reset: moving to HEAD~2
0aee51f HEAD@{21}: reset: moving to HEAD@{1}
f916d93 HEAD@{22}: reset: moving to HEAD@{1}
0aee51f HEAD@{23}: reset: moving to HEAD@{1}
f916d93 HEAD@{24}: reset: moving to HEAD^
0aee51f HEAD@{25}: commit (amend): 3rd commmit
35a7332 HEAD@{26}: checkout: moving from temp2_new_br to temp2_new_br
35a7332 HEAD@{27}: commit (amend): 3rd commmit
72c0be8 HEAD@{28}: commit (amend): 3rd commmit

An example could be that I did local-commits a->b->c->d and then I went back discarding 2 commits to check my code - git reset HEAD~2 - and then after that I want to move my HEAD back to d - git reset HEAD@{1}.

This error

Failure [INSTALL_FAILED_OLDER_SDK]

Means that you're trying to install an app that has a higher minSdkVersion specified in its manifest than the device's API level. Change that number to 8 and it should work. I'm not sure about the other error, but it may be related to this one.

How I do:

# Remove python2
sudo apt purge -y python2.7-minimal

# You already have Python3 but 
# don't care about the version 
sudo ln -s /usr/bin/python3 /usr/bin/python

# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip

# Confirm the new version of Python: 3
python --version

to copy one list into the other list, u can use the method called Collection.copy(myObject myTempObject).now after executing these line of code u can see all the list values in the myObject.

use this

ng-if="area == false"

OR

ng-if="area == true"

this may help someone

What about inv?

e.g.: my_inverse_array = inv(my_array)

This is a late answer. Starting from SQLIte 3.24.0, released on June 4, 2018, there is finally a support for UPSERT clause following PostgreSQL syntax.

INSERT INTO players (user_name, age)
  VALUES('steven', 32) 
  ON CONFLICT(user_name) 
  DO UPDATE SET age=excluded.age;

Note: For those having to use a version of SQLite earlier than 3.24.0, please reference this answer below (posted by me, @MarqueIV).

However if you do have the option to upgrade, you are strongly encouraged to do so as unlike my solution, the one posted here achieves the desired behavior in a single statement. Plus you get all the other features, improvements and bug fixes that usually come with a more recent release.

By using System.exit(0); you would close the entire process. Is that what you wanted or did you intend to close only the GUI window and allow the process to continue running?

The quickest, easiest and most robust way to simply close a JFrame or JPanel with the click of a JButton is to add an actionListener to the JButton which will execute the line of code below when the JButton is clicked:

this.dispose();

If you are using the NetBeans GUI designer, the easiest way to add this actionListener is to enter the GUI editor window and double click the JButton component. Doing this will automatically create an actionListener and actionEvent, which can be modified manually by you.

If you use

<select [ngModel]="object">
    <option *ngFor="let object of objects" [ngValue]="object">{{object.name}}</option>
</select>

You need to set the property object in you components class to the item from objects that you want to have pre-selected.

class MyComponent {
  object;
  objects = [{name: 'a'}, {name: 'b'}, {name: 'c'}];
  constructor() {
    this.object = this.objects[1];
  }
}

java.lang.ClassNotFoundException is indicate that class is not found in class path. it could be the version of log4j is not compatible. check for different log4j version.

I know you asked for Windows but thought I'd add this anyway,in Unix/Linux you could do:

cp `ls -t1 | head -1` /somedir/

Which will list all files in the current directory sorted by modification time and then cp the most recent to /somedir/

In case you are using SVN 1.7+ there is a workaround described here.

Just to recap:

1. Go to the folder with the file causing problems
2. Execute command svn update --set-depth empty (note: this will delete your files, so make a copy first!)
3. Execute command svn update --set-depth infinity

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

Because by default jQuery serializes objects passed as the data parameter to $.ajax. It uses $.param to convert the data to a query string.

From the jQuery docs for $.ajax:

[the data argument] is converted to a query string, if not already a string

If you want to send JSON, you'll have to encode it yourself:

data: JSON.stringify(arr);

Note that JSON.stringify is only present in modern browsers. For legacy support, look into json2.js

TL;DR

if (a) b else c

^ is what you can use instead of the ternary operator expression a ? b : c which Kotlin syntax does not allow.

In Kotlin, many control statements, such as if, when, and even try, can be used as expressions. As a result, these statements can have a result which may be assigned to a variable, be returned from a function, etc.

Syntactically, there's no need for ternary operator

As a result of Kotlin's expressions, the language does not really need the ternary operator.

if (a) b else c

is what you can use instead of the ternary operator expression a ? b : c.

I think the idea is that the former expression is more readable since everybody knows what ifelse does, whereas ? : is rather unclear if you're not familiar with the syntax already.

Nevertheless, I have to admit that I often miss the more convenient ternary operator.

Other Alternatives

when

You might also see when constructs used in Kotlin when conditions are checked. It's also a way to express if-else cascades in an alternative way. The following corresponds to the OTs example.

when(a) {
    true -> b
    false -> c
}

Extensions

As many good examples (Kotlin Ternary Conditional Operator) in the other answers show, extensions can also help with solving your use case.

I'd use the code in the original question, but if you really wanted to use foreach and have an integer index in C#:

foreach (int i in Enumerable.Range(0, myArray.Length).Reverse())
{
    myArray[i] = 42; 
}

There is a well-known function that can handle this:

from sklearn.model_selection import train_test_split
X, _, Y, _ = train_test_split(X,Y, test_size=0.0)

Just setting test_size to 0 will avoid splitting and give you shuffled data. Though it is usually used to split train and test data, it does shuffle them too.
From documentation

Split arrays or matrices into random train and test subsets

Quick utility that wraps input validation and next(ShuffleSplit().split(X, y)) and application to input data into a single call for splitting (and optionally subsampling) data in a oneliner.

I was struggling with this for some time and after some help on a post I was able to come up with this formula =(DATEVALUE(LEFT(XX,10)))+(TIMEVALUE(MID(XX,12,5))) where XX is the cell in reference.

I've come across many other forums with people asking the same thing and this, to me, seems to be the simplest answer. What this will do is return text that is copied in from this format 2014/11/20 11:53 EST and turn it in to a Date/Time format so it can be sorted oldest to newest. It works with short date/long date and if you want the time just format the cell to display time and it will show. Hope this helps anyone who goes searching around like I did.

Swift 4 Solution :

@IBInspectable var backgroundImage: UIImage? {
    didSet {
        UIGraphicsBeginImageContext(self.frame.size)
        backgroundImage?.draw(in: self.bounds)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        if let image = image{
            self.backgroundColor = UIColor(patternImage: image)
        }
    }
}

I can see it's an old question, if you want to put other HTML inside could use the radiobutton with GroupName propery same in all radiobuttons and in the Text property set something like an image or the html you need.

   <asp:RadioButton GroupName="group1" runat="server" ID="paypalrb" Text="<img src='https://www.paypalobjects.com/webstatic/mktg/logo/bdg_secured_by_pp_2line.png' border='0' alt='Secured by PayPal' style='width: 103px; height: 61px; padding:10px;'>" />

There is a technical aspect that should be emphasized, too. Say you need comparison behavior parameterization from a client class, and you are wondering whether to use Comparable or Comparator for a method like this:

class Pokemon {
    int healthPoints;
    int attackDamage;
    public void battle (Comparable<Pokemon> comparable, Pokemon opponent) {
        if (comparable.compareTo(opponent) > 0) { //comparable needs to, but cannot, access this.healthPoints for example
            System.out.println("battle won");
        } else {
            System.out.println("battle lost");
        }
    }
}

comparable would a lambda or an object, and there is no way for comparable to access the fields of this Pokemon. (In a lambda, this refers to the outer class instance in the lambda's scope, as defined in the program text.) So this doesn't fly, and we have to use a Comparator with two arguments.

If you not want include other function like 'ReDimPreserve' could use temporal matrix for resizing. On based to your code:

 Dim n As Integer, m As Integer, i as Long, j as Long
 Dim arrTemporal() as Variant

    n = 1
    m = 0
    Dim arrCity() As String
    ReDim arrCity(n, m)

    n = n + 1
    m = m + 1

    'VBA automatically adapts the size of the receiving matrix.
    arrTemporal = arrCity
    ReDim arrCity(n, m)

    'Loop for assign values to arrCity
    For i = 1 To UBound(arrTemporal , 1)
        For j = 1 To UBound(arrTemporal , 2)
            arrCity(i, j) = arrTemporal (i, j)
        Next
    Next

If you not declare of type VBA assume that is Variant.

Dim n as Integer, m As Integer

In my Windows 7 box I found netbeans.conf in <Drive>:\<Program Files folder>\<NetBeans installation folder>\etc . Thanks all.

I like the top-voted answer by Dan McNevin. I ended up doing the sequence of git commands too many times and decided to make a script. So here it is:

#!/bin/bash

# Usage
usage() {
    echo "Usage: ${0} -m [ master-branch-directory ] -r [ remote-branch-directory ] [ project-name ]"
    exit 1
}

# Defaults
defaults() {
    masterdir="${HOME}/Dropbox/git"
    remotedir="${PWD}"
    gitignorefile="# OS generated files #\n\n.DS_Store\n.DS_Store?\n.Spotlight-V100\n.Trashes\nehthumbs.db\nThumbs.db"
}

# Check if no arguments
if [ ${#} -eq 0 ] ; then
    echo "Error: No arguments specified"
    usage
fi

#Set defaults
defaults

# Parse arguments
while [ ${#} -ge 1 ]; do
    case "${1}" in
        '-h' | '--help' ) usage ;;
        '-m' )
            shift
            masterdir="${1}"
            ;;
        '-r' )
            shift
            remotedir="${1}"
            ;;
        * )
            projectname="${1##*/}"
            projectname="${projectname%.git}.git"
            ;;
    esac
    shift
done

# check if specified directories and project name exists
if [ -z "${projectname}" ]; then
    echo "Error: Project name not specified"
    usage
fi

if [ ! -d "${remotedir}" ]; then
    echo "Error: Remote directory ${remotedir} does not exist"
    usage
fi

if [ ! -d "${masterdir}" ]; then
    echo "Error: Master directory ${masterdir} does not exist"
    usage
fi

#absolute paths
remotedir="`( cd \"${remotedir}\" && pwd )`"
masterdir="`( cd \"${masterdir}\" && pwd )`"

#Make master git repository
cd "${masterdir}"
git init --bare "${projectname}"

#make local repository and push to master
cd "${remotedir}"
echo -e "${gitignorefile}" > .gitignore # default .gitignore file
git init
git add .
git commit -m "first commit"
git remote add origin "${masterdir}/${projectname}"
git push -u origin master

#done
echo "----- Locations -----"
echo "Remote branch location: ${remotedir}"
echo "Master branch location: ${masterdir}"
echo "Project Name: ${projectname}"

The script only requires a project name. It will generate a git repository in ~/Dropbox/git/ under the specified name and will push the entire contents of the current directory to the newly created origin master branch. If more than one project name is given, the right-most project name argument will be used.

Optionally, the -r command argument specifies the remote branch that will push to the origin master. The location of the project origin master can also be specified with the -m argument. A default .gitignore file is also placed in the remote branch directory. The directory and .gitignore file defaults are specified in the script.

This can be done in a much simpler manner now.

$tmpName = $_FILES['csv']['tmp_name'];
$csvAsArray = array_map('str_getcsv', file($tmpName));

This will return you a parsed array of your CSV data. Then you can just loop through it using a foreach statement.

alter table User 
    add constraint userProperties
    foreign key (properties)
    references Properties(ID)

Using the "Add Service Reference" tool in Visual Studio, you can insert the address as:

file:///path/to/wsdl/file.wsdl

And it will load properly.

In Xcode 8 beta 4 does not work...

Use:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
    print("Are we there yet?")
}

for async two ways:

DispatchQueue.main.async {
    print("Async1")
}

DispatchQueue.main.async( execute: {
    print("Async2")
})

I am using CentOS and had same problem.

I changed /usr/local/bin/composer to /usr/bin/composer and it worked.

Run below command :

curl -sS https://getcomposer.org/installer | php sudo mv composer.phar /usr/bin/composer

Verify Composer is installed or not

composer --version

Solution to this is:

1. use dataType: json
2. add &callback=? to your url

this worked on calling Facebook API and with Firefox. Firebug is using GET instead of OPTIONS with the above conditions (both of them).

1. You can change your the Build Target for your project at any time:

   Right-click the project in the Package Explorer, select Properties, select Android and then check the desired Project Target.

2. Edit the following elements in the AndroidManifest.xml file (it is in your project root directory)

   In this case, that will be:

   <uses-sdk android:minSdkVersion="3" />
   <uses-sdk android:targetSdkVersion="8" />
   

   Save it

3. Rebuild your project.

   Click the Project on the menu bar, select Clean...

4. Now, run the project again.

   Right Click Project name, move on Run as, and select Android Application

By the way, reviewing Managing Projects from Eclipse with ADT will be helpful. Especially the part called Creating an Android Project.

My implementation:

import math
n = 100
marked = {}
for i in range(2, int(math.sqrt(n))):
    if not marked.get(i):
        for x in range(i * i, n, i):
            marked[x] = True

for i in range(2, n):
    if not marked.get(i):
        print i

You have two ways to enable it.

First, you can set the absolute path of the php module file in your httpd.conf file like this:

LoadModule php5_module /path/to/mods-available/libphp5.so

Second, you can link the module file to the mods-enabled directory:

ln -s /path/to/mods-available/libphp5.so /path/to/mods-enabled/libphp5.so

As an additional info to Joey's answer, which isn't described in the help of set /? nor for /?.

%~0 expands to the name of the own batch, exactly as it was typed.
So if you start your batch it will be expanded as

%~0   - mYbAtCh
%~n0  - mybatch
%~nx0 - mybatch.bat

But there is one exception, expanding in a subroutine could fail

echo main- %~0
call :myFunction
exit /b

:myFunction
echo func - %~0
echo func - %~n0
exit /b

This results to

main - myBatch
Func - :myFunction
func - mybatch

In a function %~0 expands always to the name of the function, not of the batch file.
But if you use at least one modifier it will show the filename again!

If you already have test classes you may:

1) Put a cursor on a class declaration and press Alt + Enter. In the dialogue choose JUnit and press Fix. This is a standard way to create test classes in IntelliJ.

2) Alternatively you may add JUnit jars manually (download from site or take from IntelliJ files).

I'm starting to learn how to code with Swift and was trying to solve this too, this is what I came up with on Swift's playground:

// Code
var x = 1
var y = 2
var lowX = 1
var lowY = 1
var highX = 3
var highY = 3


if (x, y) >= (lowX, lowY) && (x, y) <= (highX, highY ) {
    print("inside")
} else {
    print("not inside")
}

It prints inside

    System.out.println(s.substring(startIndex + 1, endIndex));

Forward Proxy vs. Reverse Proxy (2012) explains the difference between forward and reverse proxies very clearly.

qyb2zm302's answer nicely details applications of proxies, but it slips up on the fundamental concept between forward and reverse proxies. For the reverse proxy, X → Y → Z, X knows about Y and not Z, rather than vice versa.

A proxy is simply a middleman for communication (requests + responses). Client <-> Proxy <-> Server

• Client proxy: ( client <-> proxy ) <-> server

The proxy acts on behalf of the client. The client knows about all three machines involved in the chain. The server doesn't.

• Server proxy: client <-> ( proxy <-> server )

The proxy acts on behalf of the server. The client only knows about the proxy. The server knows the whole chain.

It seems to me that forward and reverse are simply confusing, perspective-dependent names for client and server proxy. I suggest abandoning the former for the latter, for explicit communication.

Of course, to further complicate the matter, not every machine is exclusively a client or a server. If there is an ambiguity in context, it's best to explicitly specify where the proxy lies, and the communications that it tunnels.

For the record, this is documented in How do I add resources to my JAR? (illustrated for unit tests but the same applies for a "regular" resource):

To add resources to the classpath for your unit tests, you follow the same pattern as you do for adding resources to the JAR except the directory you place resources in is ${basedir}/src/test/resources. At this point you would have a project directory structure that would look like the following:

my-app
|-- pom.xml
`-- src
    |-- main
    |   |-- java
    |   |   `-- com
    |   |       `-- mycompany
    |   |           `-- app
    |   |               `-- App.java
    |   `-- resources
    |       `-- META-INF
    |           |-- application.properties
    `-- test
        |-- java
        |   `-- com
        |       `-- mycompany
        |           `-- app
        |               `-- AppTest.java
        `-- resources
            `-- test.properties

In a unit test you could use a simple snippet of code like the following to access the resource required for testing:

...

// Retrieve resource
InputStream is = getClass().getResourceAsStream("/test.properties" );

// Do something with the resource

...

Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).

Here's the code relevant for your GUESTS Table.

1. Create AUDIT Table.

    IF NOT EXISTS
          (SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[Audit]') 
                   AND OBJECTPROPERTY(id, N'IsUserTable') = 1)
           CREATE TABLE Audit 
                   (Type CHAR(1), 
                   TableName VARCHAR(128), 
                   PK VARCHAR(1000), 
                   FieldName VARCHAR(128), 
                   OldValue VARCHAR(1000), 
                   NewValue VARCHAR(1000), 
                   UpdateDate datetime, 
                   UserName VARCHAR(128))
    GO

2. CREATE an UPDATE Trigger on the GUESTS Table as follows.

    CREATE TRIGGER TR_GUESTS_AUDIT ON GUESTS FOR UPDATE
    AS
    
    DECLARE @bit INT ,
           @field INT ,
           @maxfield INT ,
           @char INT ,
           @fieldname VARCHAR(128) ,
           @TableName VARCHAR(128) ,
           @PKCols VARCHAR(1000) ,
           @sql VARCHAR(2000), 
           @UpdateDate VARCHAR(21) ,
           @UserName VARCHAR(128) ,
           @Type CHAR(1) ,
           @PKSelect VARCHAR(1000)
           
    
    --You will need to change @TableName to match the table to be audited. 
    -- Here we made GUESTS for your example.
    SELECT @TableName = 'GUESTS'
    
    -- date and user
    SELECT         @UserName = SYSTEM_USER ,
           @UpdateDate = CONVERT (NVARCHAR(30),GETDATE(),126)
    
    -- Action
    IF EXISTS (SELECT * FROM inserted)
           IF EXISTS (SELECT * FROM deleted)
                   SELECT @Type = 'U'
           ELSE
                   SELECT @Type = 'I'
    ELSE
           SELECT @Type = 'D'
    
    -- get list of columns
    SELECT * INTO #ins FROM inserted
    SELECT * INTO #del FROM deleted
    
    -- Get primary key columns for full outer join
    SELECT @PKCols = COALESCE(@PKCols + ' and', ' on') 
                   + ' i.' + c.COLUMN_NAME + ' = d.' + c.COLUMN_NAME
           FROM    INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk ,
    
                  INFORMATION_SCHEMA.KEY_COLUMN_USAGE c
           WHERE   pk.TABLE_NAME = @TableName
           AND     CONSTRAINT_TYPE = 'PRIMARY KEY'
           AND     c.TABLE_NAME = pk.TABLE_NAME
           AND     c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME
    
    -- Get primary key select for insert
    SELECT @PKSelect = COALESCE(@PKSelect+'+','') 
           + '''<' + COLUMN_NAME 
           + '=''+convert(varchar(100),
    coalesce(i.' + COLUMN_NAME +',d.' + COLUMN_NAME + '))+''>''' 
           FROM    INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk ,
                   INFORMATION_SCHEMA.KEY_COLUMN_USAGE c
           WHERE   pk.TABLE_NAME = @TableName
           AND     CONSTRAINT_TYPE = 'PRIMARY KEY'
           AND     c.TABLE_NAME = pk.TABLE_NAME
           AND     c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME
    
    IF @PKCols IS NULL
    BEGIN
           RAISERROR('no PK on table %s', 16, -1, @TableName)
           RETURN
    END
    
    SELECT         @field = 0,

           SELECT @char = ((@field - 1) / 8) + 1
           IF SUBSTRING(COLUMNS_UPDATED(),@char, 1) & @bit > 0

Try setting host=127.0.0.1 on your db settings file, it worked for me! :)

Hope it helps!

This actually sums it up pretty nicely.

API Levels generally mean that as a programmer, you can communicate with the devices' built in functions and functionality. As the API level increases, functionality adds up (although some of it can get deprecated).

Choosing an API level for an application development should take at least two thing into account:

1. Current distribution - How many devices can actually support my application, if it was developed for API level 9, it cannot run on API level 8 and below, then "only" around 60% of devices can run it (true to the date this post was made).
2. Choosing a lower API level may support more devices but gain less functionality for your app. you may also work harder to achieve features you could've easily gained if you chose higher API level.

Android API levels can be divided to five main groups (not scientific, but what the heck):

1. Android 1.5 - 2.3 (Cupcake to Gingerbread) - (API levels 3-10) - Android made specifically for smartphones.
2. Android 3.0 - 3.2 (Honeycomb) (API levels 11-13) - Android made for tablets.
3. Android 4.0 - 4.4 (KitKat) - (API levels 14-19) - A big merge with tons of additional functionality, totally revamped Android version, for both phone and tablets.
4. Android 5.0 - 5.1 (Lollipop) - (API levels 21-22) - Material Design introduced.
5. Android 6.0 - 6.… (Marshmallow) - (API levels 23-…) - Runtime Permissions,Apache HTTP Client Removed

Floating-point numbers, also known as real numbers, are used when evaluating expressions that require fractional precision. For example, calculations such as square root, or transcendentals such as sine and cosine, result in a value whose precision requires a floating-point type. Java implements the standard (IEEE–754) set of floatingpoint types and operators. There are two kinds of floating-point types, float and double, which represent single- and double-precision numbers, respectively. Their width and ranges are shown here:

   Name     Width in Bits   Range 
    double  64              1 .7e–308 to 1.7e+308
    float   32              3 .4e–038 to 3.4e+038

float

The type float specifies a single-precision value that uses 32 bits of storage. Single precision is faster on some processors and takes half as much space as double precision, but will become imprecise when the values are either very large or very small. Variables of type float are useful when you need a fractional component, but don't require a large degree of precision.

Here are some example float variable declarations:

float hightemp, lowtemp;

double

Double precision, as denoted by the double keyword, uses 64 bits to store a value. Double precision is actually faster than single precision on some modern processors that have been optimized for high-speed mathematical calculations. All transcendental math functions, such as sin( ), cos( ), and sqrt( ), return double values. When you need to maintain accuracy over many iterative calculations, or are manipulating large-valued numbers, double is the best choice.

Just updating screenshots to help others as I am using a newer v18, circa 2019.

Here you can select certain tables or go with the default of all. For my own needs I'm indicating just the one table.

Next, there's the "Scripting Options" where you can choose output file, etc. As in multiple answers above (again, I'm just dusting off old answers for newer, v18.4 SQL Server Management Studio) what we're really wanting is under the "Advanced" button. For my own purposes, I need just the data.

Finally, there's a review summary before execution. After executing a report of operations' status is shown.

First of all you need to make the field Nullable, then after that so simple - instead of putting a value put this code CURRENT_TIMESTAMP.

You need to specify workseet. Change line

If Worksheet.Cells(i, 1).Value = "X" Then

to

If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then

UPD:

Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):

Sub LastRowInOneColumn()
   Dim LastRow As Long
   Dim i As Long, j As Long

   'Find the last used row in a Column: column A in this example
   With Worksheets("Sheet2")
      LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
   End With

   MsgBox (LastRow)
   'first row number where you need to paste values in Sheet1'
   With Worksheets("Sheet1")
      j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
   End With 

   For i = 1 To LastRow
       With Worksheets("Sheet2")
           If .Cells(i, 1).Value = "X" Then
               .Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
               j = j + 1
           End If
       End With
   Next i
End Sub

This does work for a specific delimiter for a specific amount of characters between the delimiter. I had many issues attempting to use this in a for each loop where the position changed but the delimiter was the same. For example I was using the backslash as the delimiter and wanted to only use everything to the right of the backslash. The issue was that once the position was defined (71 characters from the beginning) it would use $pos as 71 every time regardless of where the delimiter actually was in the script. I found another method of using a delimiter and .split to break things up then used the split variable to call the sections For instance the first section was $variable[0] and the second section was $variable[1].

For those who use AngularJs, it's $http.get:

$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

There wasn't any luck here with the other answers, but I managed to work it out with this nice one-liner:

((GuidAttribute)(AppDomain.CurrentDomain.DomainManager.EntryAssembly).GetCustomAttributes(typeof(GuidAttribute), true)[0]).Value

• X-XSS-Protection: 1 : Force XSS protection (useful if XSS protection was disabled by the user)

• X-XSS-Protection: 0 : Disable XSS protection

• The token mode=block will prevent browser (IE8+ and Webkit browsers) to render pages (instead of sanitizing) if a potential XSS reflection (= non-persistent) attack is detected.

/!\ Warning, mode=block creates a vulnerability in IE8 (more info).

This is best done in the MenuItemDataBound.

protected void NavigationMenu_MenuItemDataBound(object sender, MenuEventArgs e)
{
    if (!Page.User.IsInRole("Admin"))
    {
        if (e.Item.NavigateUrl.Equals("/admin"))
        {
            if (e.Item.Parent != null)
            {
                MenuItem menu = e.Item.Parent;

                menu.ChildItems.Remove(e.Item);
            }
            else
            {
                Menu menu = (Menu)sender;

                menu.Items.Remove(e.Item);
            }               
        }
    }
}

Because the example used the NavigateUrl it is not language specific and works on sites with localized site maps.

use this format....

//get current date in javascript

  var currentDate = new Date();


// for getting a date from a textbox as string format

   var newDate=document.getElementById("<%=textBox1.ClientID%>").value;

// convert this date to date time

   var MyDate = new Date(newDate);

If the constructor with width, height and weight is not working, try using the constructor with width and height. And then manually set the weight.

And if you want the width to be set according to the weight, set width as 0 in the constructor. Same applies for height. Below code works for me.

LinearLayout.LayoutParams childParam1 = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.MATCH_PARENT);
childParam1.weight = 0.3f;
child1.setLayoutParams(childParam1);

LinearLayout.LayoutParams childParam2 = new LinearLayout.LayoutParams(0,LinearLayout.LayoutParams.MATCH_PARENT);
childParam2.weight = 0.7f;
child2.setLayoutParams(childParam2);

parent.setWeightSum(1f);
parent.addView(child1);
parent.addView(child2);

You have 2 options, and I am not sure if I am a fan of either of them, but that is my opinion. You may feel differently:

Option 1: Force the function to run.

A function in a cell does not run unless it references a cell that has changed. Changing a sheet name does not trigger any functions in the spreadsheet. But we can force the function to run by passing a range to it and whenever an item in that range changes, the function will trigger.

You can use the below script to create a custom function which will retrieve the name:

function mySheetName() {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  return key;
}

and in the cell place the following:

=mySheetName(A1:Z)

Now if any value in a cell in that passed range changes the script will run. This takes a second to run the script and sets a message in the cell each time any value is changed so this could become annoying very quickly. As already mentioned, it also requires a change in the range to cause it to trigger, so not really helpful on a fairly static file.

Option 2: Use the OnChange Event

While the run time feels better than the above option, and this does not depend on a value changing in the spreadsheet's cells, I do not like this because it forces where the name goes. You could use a Utilities sheet to define this location in various sheets if you wish. Below is the basic idea and may get you started if you like this option.

The OnChange event is triggered when the sheet name is changed. You can make the code below more sophisticated to check for errors, check the sheet ID to only work on a given sheet, etc. The basic code, however, is:

function setSheetName(e) {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange('K1').setValue(key);
}

Once you have saved the code, in the script editor set the Current Project's On Change Trigger to this function. It will write the sheet name to cell K1 on any change event. To set the trigger, select Current project's triggers under the Edit menu.

I think my answer to my own question here is the simplest solution to what you are trying to do:

1. Select the cell where the first line of text from the file should be.

2. Use the Data/Get External Data/From File dialog to select the text file to import.

3. Format the imported text as required.

4. In the Import Data dialog that opens, click on Properties...

5. Uncheck the Prompt for file name on refresh box.

6. Whenever the external file changes, click the Data/Get External Data/Refresh All button.

Note: in your case, you should probably want to skip step #5.

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

You could wrap your return value in the Boolean function

Boolean([return value])

That'll ensure all falsey values are false and truthy statements are true.

The cleaner way to do this would be to inherit RouteAware and implement the onNavigationEnd() method.

It's part of a library called @bespunky/angular-zen.

1. npm install @bespunky/angular-zen

2. Make your AppComponent extend RouteAware and add an onNavigationEnd() method.

import { Component     } from '@angular/core';
import { NavigationEnd } from '@angular/router';
import { RouteAware    } from '@bespunky/angular-zen/router-x';

@Component({
    selector   : 'app-root',
    templateUrl: './app.component.html',
    styleUrls  : ['./app.component.css']
})
export class AppComponent extends RouteAware
{    
    protected onNavigationEnd(event: NavigationEnd): void
    {
        // Handle authentication...
    }
}

RouteAware has other benefits such as:
? Any router event can have a handler method (Angular's supported router events).
? Use this.router to access the router
? Use this.route to access the activated route
? Use this.componentBus to access the RouterOutletComponentBus service

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.

Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)

Alternatively you could:

In your CMD

PATH=%PATH%;C:\\path\to\node_module

EDIT

The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.

Using @yogihosting answer when she used the Microsoft built-in LinkedList and LinkedListNode to answer the question, you can achieve the same results:

using System;
using System.Collections.Generic;
using Codebase;

namespace Cmd
{
    static class Program
    {
        static void Main(string[] args)
        {
            var tune = new LinkedList(); //Using custom code instead of the built-in LinkedList<T>
            tune.AddFirst("do"); // do
            tune.AddLast("so"); // do - so
            tune.AddAfter(tune.First, "re"); // do - re- so
            tune.AddAfter(tune.First.Next, "mi"); // do - re - mi- so
            tune.AddBefore(tune.Last, "fa"); // do - re - mi - fa- so
            tune.RemoveFirst(); // re - mi - fa - so
            tune.RemoveLast(); // re - mi - fa
            Node miNode = tune.Find("mi"); //Using custom code instead of the built in LinkedListNode
            tune.Remove(miNode); // re - fa
            tune.AddFirst(miNode); // mi- re - fa
 }
}

This requires changes to the frontend JS and the headers sent from the backend.

Frontend

Remove "mode":"no-cors" in the fetch options.

fetch(
  "http://example.com/api/docs", 
  {
    // mode: "no-cors",
    method: "GET"
  }
)
  .then(response => response.text())
  .then(data => console.log(data))

Backend

When your server responds to the request, include the CORS headers specifying the origin from where the request is coming. If you don't care about the origin, specify the * wildcard.

The raw response should include a header like this.

Access-Control-Allow-Origin: *

An extremely important consideration in the choice of Expression vs Func is that IQueryable providers like LINQ to Entities can 'digest' what you pass in an Expression, but will ignore what you pass in a Func. I have two blog posts on the subject:

More on Expression vs Func with Entity Framework and Falling in Love with LINQ - Part 7: Expressions and Funcs (the last section)

This works if you want to display in a TextBox:

@Html.TextBoxFor(m => m.Employee.DOB, "{0:dd-MM-yyyy}")

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

Works for me-

function querySt(Key) {

    var url = window.location.href;

    KeysValues = url.split(/[\?&]+/); 

    for (i = 0; i < KeysValues.length; i++) {

            KeyValue= KeysValues[i].split("=");

            if (KeyValue[0] == Key) {

                return KeyValue[1];

        }

    }

}

function GetQString(Key) {     

    if (querySt(Key)) {

         var value = querySt(Key);

         return value;        

    }

 }

puts "string".split('').map(&:ord).to_s

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.feature_wrapper span {
    float: left;
    clear: left;
    display:inline
}

EDIT: now browsers have better support you can make use of the do inline-block.

.feature_wrapper span {
    display:inline-block;
    *display:inline; *zoom:1;
}

Depending on the text-align this will appear as through its inline while also acting like a block element.

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.

You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.

If you make the relationships bidirectional, you should thus have

class User {
    @OneToMany(mappedBy = "user")
    private Set<UserService> userServices = new HashSet<UserService>();
}

class UserService {
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "service_code")
    private Service service;

    @Column(name = "blocked")
    private boolean blocked;
}

class Service {
    @OneToMany(mappedBy = "service")
    private Set<UserService> userServices = new HashSet<UserService>();
}

If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.

User user = new User();
Service service = new Service();
UserService userService = new UserService();

user.addUserService(userService);
userService.setUser(user);

service.addUserService(userService);
userService.setService(service);

session.save(user);
session.save(service);
session.save(userService);

This is what I tried for a right outer join [as per my requirement]:

m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink, 
            by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"), 
            by.y=c("company_permalink"), all.y=TRUE)

This worked.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

You could make a new tokenizer for Russian (and some other languages) using this function:

def russianTokenizer(text):
    result = text
    result = result.replace('.', ' . ')
    result = result.replace(' .  .  . ', ' ... ')
    result = result.replace(',', ' , ')
    result = result.replace(':', ' : ')
    result = result.replace(';', ' ; ')
    result = result.replace('!', ' ! ')
    result = result.replace('?', ' ? ')
    result = result.replace('\"', ' \" ')
    result = result.replace('\'', ' \' ')
    result = result.replace('(', ' ( ')
    result = result.replace(')', ' ) ') 
    result = result.replace('  ', ' ')
    result = result.replace('  ', ' ')
    result = result.replace('  ', ' ')
    result = result.replace('  ', ' ')
    result = result.strip()
    result = result.split(' ')
    return result

and then call it in this way:

text = '?? ?????????? ?????, ????????? Google SSL;'
tokens = russianTokenizer(text)

Installing webpack with -g option installs webpack in a folder in

C:\Users\<.profileusername.>\AppData\Roaming\npm\node_modules

same with webpack-cli and webpack-dev-server

Outside the global node_modules a link is created for webpack to be run from commandline

C:\Users\<.profileusername.>\AppData\Roaming\npm

to make this work locally, I did the following

1. renamed the webpack folder in global node_modules to _old
2. installed webpack locally within project
3. edited the command link webpack.cmd and pointed the webpack.js to look into my local node_modules folder within my application

Problem with this approach is you'd have to maintain links for each project you have. Theres no other way since you are using the command line editor to run webpack command when installing with a -g option.

So if you had proj1, proj2 and proj3 all with their local node_modules and local webpack installed( not using -g when installing), then you'd have to create non-generic link names instead of just webpack.

example here would be to create webpack_proj1.cmd, webpack_proj2.cmd and webpack_proj3.cmd and in each cmd follow point 2 and 3 above

PS: dont forget to update your package.json with these changes or else you'll get errors as it won't find webpack command

This is kind of an old question but I wanted to mentioned here the pathlib library in Python3.

If you write:

from pathlib import Path
path: str = 'C:\\Users\\myUserName\\project\\subfolder'
osDir = Path(path)

or

path: str = "C:\\Users\\myUserName\\project\\subfolder"
osDir = Path(path)

osDir will be the same result.

Also if you write it as:

path: str = "subfolder"
osDir = Path(path)
absolutePath: str = str(Path.absolute(osDir))

you will get back the absolute directory as

'C:\\Users\\myUserName\\project\\subfolder'

You can check more for the pathlib library here.

I'd use absolute positioning:

#play_button {
    position:absolute;
transition: .5s ease;
    left: 202px;
    top: 198px;

}

I had a similar heroku ssh error that I could not resolve.

As a workaround, I used the new heroku http-git feature (http transport for "heroku" remote instead of ssh). Details here: https://devcenter.heroku.com/articles/http-git

(Short version: if you have a project already setup the standard way, run heroku git:remote --http-init to change "heroku" remote to http.)

A good quick work around if you don't have time to fix/troubleshoot an ssh issue.

It's really easy to do with github pages, it's just a bit weird the first time you do it. Sorta like the first time you had to juggle 3 kittens while learning to knit. (OK, it's not all that bad)

You need a gh-pages branch:

Basically github.com looks for a gh-pages branch of the repository. It will serve all HTML pages it finds in here as normal HTML directly to the browser.

How do I get this gh-pages branch?

Easy. Just create a branch of your github repo called gh-pages. Specify --orphan when you create this branch, as you don't actually want to merge this branch back into your github branch, you just want a branch that contains your HTML resources.

$ git checkout --orphan gh-pages

What about all the other gunk in my repo, how does that fit in to it?

Nah, you can just go ahead and delete it. And it's safe to do now, because you've been paying attention and created an orphan branch which can't be merged back into your main branch and remove all your code.

I've created the branch, now what?

You need to push this branch up to github.com, so that their automation can kick in and start hosting these pages for you.

git push -u origin gh-pages

But.. My HTML is still not being served!

It takes a few minutes for github to index these branches and fire up the required infrastructure to serve up the content. Up to 10 minutes according to github.

The steps layed out by github.com

https://help.github.com/articles/creating-project-pages-manually

Technically you can if you use something like OpenCL, but Nvidia's CUDA is much better and OpenCL requires other steps that may or may not work. I would recommend if you have an AMD gpu, use something like Google Colab where they provide a free Nvidia GPU you can use when coding.

These two terms differentiate between two different ways of walking a tree.

It is probably easiest just to exhibit the difference. Consider the tree:

    A
   / \
  B   C
 /   / \
D   E   F

A depth first traversal would visit the nodes in this order

A, B, D, C, E, F

Notice that you go all the way down one leg before moving on.

A breadth first traversal would visit the node in this order

A, B, C, D, E, F

Here we work all the way across each level before going down.

(Note that there is some ambiguity in the traversal orders, and I've cheated to maintain the "reading" order at each level of the tree. In either case I could get to B before or after C, and likewise I could get to E before or after F. This may or may not matter, depends on you application...)

Both kinds of traversal can be achieved with the pseudocode:

Store the root node in Container
While (there are nodes in Container)
   N = Get the "next" node from Container
   Store all the children of N in Container
   Do some work on N

The difference between the two traversal orders lies in the choice of Container.

• For depth first use a stack. (The recursive implementation uses the call-stack...)
• For breadth-first use a queue.

The recursive implementation looks like

ProcessNode(Node)
   Work on the payload Node
   Foreach child of Node
      ProcessNode(child)
   /* Alternate time to work on the payload Node (see below) */

The recursion ends when you reach a node that has no children, so it is guaranteed to end for finite, acyclic graphs.

At this point, I've still cheated a little. With a little cleverness you can also work-on the nodes in this order:

D, B, E, F, C, A

which is a variation of depth-first, where I don't do the work at each node until I'm walking back up the tree. I have however visited the higher nodes on the way down to find their children.

This traversal is fairly natural in the recursive implementation (use the "Alternate time" line above instead of the first "Work" line), and not too hard if you use a explicit stack, but I'll leave it as an exercise.

If you're using a UINavigationController, you can use an extension like this:

extension UINavigationController {
    private struct AssociatedKeys {
        static var navigationBarBackgroundViewName = "NavigationBarBackground"
    }

    var navigationBarBackgroundView: UIView? {
        get {
            return objc_getAssociatedObject(self,
                                        &AssociatedKeys.navigationBarBackgroundViewName) as? UIView
        }
        set(newValue) {
             objc_setAssociatedObject(self,
                                 &AssociatedKeys.navigationBarBackgroundViewName,
                                 newValue,
                                 .OBJC_ASSOCIATION_RETAIN)
        }
    }

    func setNavigationBar(hidden isHidden: Bool, animated: Bool = false) {
       if animated {
           UIView.animate(withDuration: 0.3) {
               self.navigationBarBackgroundView?.isHidden = isHidden
           }
       } else {
           navigationBarBackgroundView?.isHidden = isHidden
       }
    }

    func setNavigationBarBackground(color: UIColor, includingStatusBar: Bool = true, animated: Bool = false) {
        navigationBarBackgroundView?.backgroundColor = UIColor.clear
        navigationBar.backgroundColor = UIColor.clear
        navigationBar.barTintColor = UIColor.clear

        let setupOperation = {
            if includingStatusBar {
                self.navigationBarBackgroundView?.isHidden = false
                if self.navigationBarBackgroundView == nil {
                    self.setupBackgroundView()
                }
                self.navigationBarBackgroundView?.backgroundColor = color
            } else {
                self.navigationBarBackgroundView?.isHidden = true
                self.navigationBar.backgroundColor = color
            }
        }

        if animated {
            UIView.animate(withDuration: 0.3) {
                setupOperation()
            }
        } else {
            setupOperation()
        }
    }

    private func setupBackgroundView() {
        var frame = navigationBar.frame
        frame.origin.y = 0
        frame.size.height = 64

        navigationBarBackgroundView = UIView(frame: frame)
        navigationBarBackgroundView?.translatesAutoresizingMaskIntoConstraints = true
        navigationBarBackgroundView?.autoresizingMask = [.flexibleWidth, .flexibleBottomMargin]

        navigationBarBackgroundView?.isUserInteractionEnabled = false

        view.insertSubview(navigationBarBackgroundView!, aboveSubview: navigationBar)
    }
}

It basically makes the navigation bar background transparent and uses another UIView as the background. You can call the setNavigationBarBackground method of your navigation controller to set the navigation bar background color together with the status bar.

Keep in mind that you have to then use the setNavigationBar(hidden: Bool, animated: Bool) method in the extension when you want to hide the navigation bar otherwise the view that was used as the background will still be visible.

One way to do this is with a delegate

List<cTag> week = new List<cTag>();
// add some stuff to the list
// now sort
week.Sort(delegate(cTag c1, cTag c2) { return c1.date.CompareTo(c2.date); });

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

To reduce the required packages to install you just need

apt-get install -y \
    libfreetype6-dev \
    libxft-dev && \
    pip install matplotlib

and you will get the following packages locally installed

Lambda expressions, even captured ones, can be handled as a function pointer (pointer to member function).

It is tricky because an lambda expression is not a simple function. It is actually an object with an operator().

When you are creative, you can use this! Think of an "function" class in style of std::function. If you save the object you also can use the function pointer.

To use the function pointer, you can use the following:

int first = 5;
auto lambda = [=](int x, int z) {
    return x + z + first;
};
int(decltype(lambda)::*ptr)(int, int)const = &decltype(lambda)::operator();
std::cout << "test = " << (lambda.*ptr)(2, 3) << std::endl;

To build a class that can start working like a "std::function", first you need a class/struct than can store object and function pointer. Also you need an operator() to execute it:

// OT => Object Type
// RT => Return Type
// A ... => Arguments
template<typename OT, typename RT, typename ... A>
struct lambda_expression {
    OT _object;
    RT(OT::*_function)(A...)const;

    lambda_expression(const OT & object)
        : _object(object), _function(&decltype(_object)::operator()) {}

    RT operator() (A ... args) const {
        return (_object.*_function)(args...);
    }
};

With this you can now run captured, non-captured lambdas, just like you are using the original:

auto capture_lambda() {
    int first = 5;
    auto lambda = [=](int x, int z) {
        return x + z + first;
    };
    return lambda_expression<decltype(lambda), int, int, int>(lambda);
}

auto noncapture_lambda() {
    auto lambda = [](int x, int z) {
        return x + z;
    };
    return lambda_expression<decltype(lambda), int, int, int>(lambda);

If you want to alter order for columns in Sql server, There is no direct way to do this in SQL Server currently.

Have a look at http://blog.sqlauthority.com/2008/04/08/sql-server-change-order-of-column-in-database-tables/

You can change order while edit design for table.

Use suppressWarnings():

suppressWarnings(as.numeric(c("1", "2", "X")))
[1]  1  2 NA

This suppresses warnings.

In general, the cause of the problem could be the following:

You started a new project with the new virtual environment. So probably you install numpy from the terminal, but it is not in your venv. So

• either install it from PyCahrm Interface: Settings -> Project Interpreter -> Add the package

• or activate your venv and -> pip install numPy

Try simply to reset last commit using --soft flag

git reset --soft HEAD~1

Note :

For Windows, wrap the HEAD parts in quotes like git reset --soft "HEAD~1"

As Dave already pointed out, you could run your Service with foreground priority. But this practice should only be used when it's absolutely necessary, i.e. when it would cause a bad user experience if the Service got killed by Android. This is what the "foreground" really means: Your app is somehow in the foreground and the user would notice it immediately if it's killed (e.g. because it played a song or a video).

In most cases, requesting foreground priority for your Service is contraproductive!

Why is that? When Android decides to kill a Service, it does so because it's short of resources (usually RAM). Based on the different priority classes, Android decides which running processes, and this included services, to terminate in order to free resources. This is a healthy process that you want to happen so that the user has a smooth experience. If you request foreground priority, without a good reason, just to keep your service from being killed, it will most likely cause a bad user experience. Or can you guarantee that your service stays within a minimal resource consumption and has no memory leaks?¹

Android provides sticky services to mark services that should be restarted after some grace period if they got killed. This restart usually happens within a few seconds.

Image you want to write an XMPP client for Android. Should you request foreground priority for the Service which contains your XMPP connection? Definitely no, there is absolutely no reason to do so. But you want to use START_STICKY as return flag for your service's onStartCommand method. So that your service is stopped when there is resource pressure and restarted once the situation is back to normal.

¹: I am pretty sure that many Android apps have memory leaks. It something the casual (desktop) programmer doesn't care that much about.

The following also seems to work :

for (vector<int>::iterator it = res.begin(); it != res.end(); it++)
{
  res.erase(it--);
}

Not sure if there's any flaw in this ?

for more exactly positioning:

      background-position: bottom 5px right 7px;

declare @ids nvarchar(1000)

set @ids = '100,2,3,4,5' --Parameter passed

set @ids = ',' + @ids + ','

select   *
from     TableName 
where    charindex(',' + CAST(Id as nvarchar(50)) + ',', @ids) > 0

While I agree with the results given, they didn't work for me. If your Table has a name this will work:

Public Sub GetCountOfResults(WorkSheetName As String, TableName As String)
    Dim rnData As Range
    Dim rngArea As Range
    Dim lCount As Long
        Set rnData = ThisWorkbook.Worksheets(WorkSheetName).ListObjects(TableName).Range
    With rnData
        For Each rngArea In .SpecialCells(xlCellTypeVisible).Areas
            lCount = lCount + rngArea.Rows.Count
        Next
        MsgBox "Autofilter " & lCount - 1 & " records"
    End With
    Set rnData = Nothing
    lCount = Empty      
End Sub

This is modified to work with ListObjects from an original version I found here:

Even after applying everything I have mentioned, I've still had dramas with the images. In the end, i've just used Gimp to create a 'flipped vertical' version of all my images. Now I don't need to use any Transforms. Hopefully this won't cause further problems down the track.

Does anyone know why CGContextDrawImage would be drawing my image upside down? I am loading an image in from my application:

Quartz2d uses a different co-ordinate system, where the origin is in the lower left corner. So when Quartz draws pixel x[5], y[10] of a 100 * 100 image, that pixel is being drawn in the lower left corner instead of the upper left. Thus causing the 'flipped' image.

The x co-ordinate system matches, so you will need to flip the y co-ordinates.

CGContextTranslateCTM(context, 0, image.size.height);

This means we have translated the image by 0 units on the x axis and by the images height on the y axis. However, this alone will mean our image is still upside down, just being drawn "image.size.height" below where we wish it to be drawn.

The Quartz2D programming guide recommends using ScaleCTM and passing negative values to flip the image. You can use the following code to do this -

CGContextScaleCTM(context, 1.0, -1.0);

Combine the two just before your CGContextDrawImage call and you should have the image drawn correctly.

UIImage *image = [UIImage imageNamed:@"testImage.png"];    
CGRect imageRect = CGRectMake(0, 0, image.size.width, image.size.height);       

CGContextTranslateCTM(context, 0, image.size.height);
CGContextScaleCTM(context, 1.0, -1.0);

CGContextDrawImage(context, imageRect, image.CGImage);

Just be careful if your imageRect co-ordinates do not match those of your image, as you can get unintended results.

To convert back the coordinates:

CGContextScaleCTM(context, 1.0, -1.0);
CGContextTranslateCTM(context, 0, -imageRect.size.height);

When using the superglobals like $_GET or $_REQUEST you should be aware that they could be an empty string. In this specal case this example

$username = $_GET['user'] ?? 'nobody';

will fail because the value of $username now is an empty string.

So when using $_GET or even $_REQUEST you should use the ternary operator instead like this:

$username = (!empty($_GET['user'])?$_GET['user']:'nobody';

Now the value of $username is 'nobody' as expected.

You can make the code run faster by shorting the selenium timeout before your try catch statement.

I use the following code to check if an element is present.

protected boolean isElementPresent(By selector) {
    selenium.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
    logger.debug("Is element present"+selector);
    boolean returnVal = true;
    try{
        selenium.findElement(selector);
    } catch (NoSuchElementException e){
        returnVal = false;
    } finally {
        selenium.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
    }
    return returnVal;
}

running make clean and then ./configure should solve your problem.

I just ran into this problem this morning and seemed very strange since my application was working fine up until today. I was getting the exact same "The Google Play services resources were not found..." message.

I tried opening the regular Google Maps application to see if I could get my location, but it wouldn't find it. Even after waiting 5 minutes, which is more than enough time to normally get a location from even the service provider via cell tower. So I checked Location Services.

Anyway, the problem turned out to be that on my S3 under Location Services -> Google Location Services. It was not checked. The other two location options were checked (VZW Location Services and Standalone GPS Services), but the last one, Google Location Services was not. After turning that on, the regular Google Maps could find my location and my application could find my location and the problem went away.

The error message pops up due to:

mMap.setMyLocationEnabled(true);

when Google Location Services is not enabled.

After doing some more testing it looks like if the current location is null (cannot be determined from all sources) then you will get this error when trying to turn on setMyLocationEnabled.

        response.add("Saved person: " + person.toString());
    }
    return response;
}

We can use Array as shown above.

Another mode is: If your editor HAS NO BLOCK comment option,

1. Open a second instance of the editor (for example File=>New File...)
2. From THE PREVIOUS file you are working on, select ONLY THE PART YOU WANT COMMENT
3. Copy and paste it in the window of the new temporary file...
4. Open the Edit menu, select REPLACE and input as string to be replaced '\n'
5. input as replace string: '\n#'
6. press the button 'replace ALL'

DONE

it WORKS with ANY editor

And if you simply want to cut part of a file - say from line 26 to 142 - and input it to a newfile : cat file-to-cut.txt | sed -n '26,142p' >> new-file.txt

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

\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}

The answer is on the example link you provided:

i.e.

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal('show');

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.

public List<Object> GetProjectForCombo()
{
   using (MyDataContext db = new MyDataContext (DBHelper.GetConnectionString()))
   {
     var query = db.Project
     .Select<IEnumerable<something>,ProjectInfo>(p=>
                 return new ProjectInfo{Name=p.ProjectName, Id=p.ProjectId);       

     return query.ToList<Object>();
   }

}

A key compatibility issue is support for persistent connections. I recently worked on a server that "supported" HTTP/1.1, yet failed to close the connection when a client sent an HTTP/1.0 request. When writing a server that supports HTTP/1.1, be sure it also works well with HTTP/1.0-only clients.

give input through your keyboard

a=float(input("enter the 1st number : "))
b=float(input("enter the 2nd number : "))
c=float(input("enter the 3rd number : "))

calculate the discriminant

d = (b**2) - (4*a*c)

possible solution are

sol_1 = (-b-(0.5**d))/(2*a)
sol_2 = (-b+(0.5**d))/(2*a)

print the result

print('The solution are  %0.f,%0.f'%(sol_1,sol_2))

String.prototype.replaceAll = function(a, b) {
    return this.replace(new RegExp(a.replace(/([.?*+^$[\]\\(){}|-])/ig, "\\$1"), 'ig'), b)
}

Test it like:

var whatever = 'Some [b]random[/b] text in a [b]sentence.[/b]'

console.log(whatever.replaceAll("[", "<").replaceAll("]", ">"))

personally, I like both analysis done every time....requests/second and average time/request and love seeing the max request time as well on top of that. it is easy to flip if you have 61 requests/second, you can then just flip it to 1000ms / 61 requests.

To answer your question, we have been doing a huge load test ourselves and find it ranges on various amazon hardware we use(best value was the 32 bit medium cpu when it came down to $$ / event / second) and our requests / seconds ranged from 29 requests / second / node up to 150 requests/second/node.

Giving better hardware of course gives better results but not the best ROI. Anyways, this post was great as I was looking for some parallels to see if my numbers where in the ballpark and shared mine as well in case someone else is looking. Mine is purely loaded as high as I can go.

NOTE: thanks to requests/second analysis(not ms/request) we found a major linux issue that we are trying to resolve where linux(we tested a server in C and java) freezes all the calls into socket libraries when under too much load which seems very odd. The full post can be found here actually.... http://ubuntuforums.org/showthread.php?p=11202389

We are still trying to resolve that as it gives us a huge performance boost in that our test goes from 2 minutes 42 seconds to 1 minute 35 seconds when this is fixed so we see a 33% performancce improvement....not to mention, the worse the DoS attack is the longer these pauses are so that all cpus drop to zero and stop processing...in my opinion server processing should continue in the face of a DoS but for some reason, it freezes up every once in a while during the Dos sometimes up to 30 seconds!!!

ADDITION: We found out it was actually a jdk race condition bug....hard to isolate on big clusters but when we ran 1 server 1 data node but 10 of those, we could reproduce it every time then and just looked at the server/datanode it occurred on. Switching the jdk to an earlier release fixed the issue. We were on jdk1.6.0_26 I believe.

Use String.Format

Pre C# 6.0

string data = "FlightA, B,C,D";
var str = String.Format("Hi We have these flights for you: {0}. Which one do you want?", data);

C# 6.0 -- String Interpolation

string data = "FlightA, B,C,D";
var str = $"Hi We have these flights for you: {data}. Which one do you want?";

http://www.informit.com/articles/article.aspx?p=2422807

ord and chr

Caveat!

The conversions occur from left to right.

Try this:

int i = 3, j = 2;
double k = 33;
cout << k * j / i << endl; // prints 22
cout << j / i * k << endl; // prints 0

try this in your command prompt: python -m pip intsall pygame

In my opinion the easiest and fastest way to get a Google Drive file ID is from Google Drive on the web. Right-click the file name and select Get shareable link. The last part of the link is the file ID. Then you can cancel the sharing.

I had very similar situation (had a project on another machine and cloned it to my laptop and saw the same issue) and I looked in it.

Error message was coming from Sdk.groovy of Android gradle plugin: https://android.googlesource.com/platform/tools/build/+/master/gradle/src/main/groovy/com/android/build/gradle/internal/Sdk.groovy

By looking at code, its findLocation needs to set androidSdkDir variable and there are only three ways to do it:

• create local.properties file and have either sdk.dir or android.dir line.
• have ANDROID_HOME environment variable defined.
• System.getProperty("android.home") - I'm not sure how it works, but it seems like a Java thing.

While your Android Studio knows that the SDK is at that place, I doubt that Android Studio is passing that information to gradle and thus we're seeing that error.

I created local.properties file at the project root and put the following line and it compiled the code successfully.

sdk.dir = /Applications/Android Studio.app/sdk/

From $http.get docs, the second parameter is a configuration object:

get(url, [config]);

Shortcut method to perform GET request.

You may change your code to:

$http.get('accept.php', {
    params: {
        source: link, 
        category_id: category
    }
});

Or:

$http({
    url: 'accept.php', 
    method: 'GET',
    params: { 
        source: link, 
        category_id: category
    }
});

As a side note, since Angular 1.6: .success should not be used anymore, use .then instead:

$http.get('/url', config).then(successCallback, errorCallback);

Either run in SQL:

ALTER TABLE tableName
  ADD PRIMARY KEY (id)           ---or Drugid, whichever you want it to be PK

or use the PHPMyAdmin interface (Table Structure)

You can do it the following way:

DoCmd.OpenQuery "yourQueryName", acViewNormal, acEdit

OR

CurrentDb.OpenRecordset("yourQueryName")

In the S3 management console, click on the checkmark for the bucket, and click on the empty button from the top right.

You can use Flexible, in this case the person.name could be a long name (Labels and BlankSpace are custom classes that return widgets) :

new Column(
  crossAxisAlignment: CrossAxisAlignment.start,
  children: <Widget>[
   new Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: <Widget>[
        new Flexible(
            child: Labels.getTitle_2(person.name,
            color: StyleColors.COLOR_BLACK)),
        BlankSpace.column(3),
        Labels.getTitle_1(person.likes())
      ]),
    BlankSpace.row(3),
    Labels.getTitle_2(person.shortDescription),
  ],
)

This script will find files having a modification date of two minutes before and after the given date (and you can change the values in the conditions as per your requirement)

PATH_SRC="/home/celvas/Documents/Imp_Task/"
PATH_DST="/home/celvas/Downloads/zeeshan/"

cd $PATH_SRC
TODAY=$(date  -d "$(date +%F)" +%s)
TODAY_TIME=$(date -d "$(date +%T)" +%s)


for f in `ls`;
do
#       echo "File -> $f"
        MOD_DATE=$(stat -c %y "$f")

#       echo MOD_DATE: $MOD_DATE
        MOD_DATE1=$(date -d "$MOD_DATE" +%s)
#       echo MOD_DATE: $MOD_DATE

DIFF_IN_DATE=$[ $MOD_DATE1 - $TODAY ]
DIFF_IN_DATE1=$[ $MOD_DATE1 - $TODAY_TIME ]
#echo DIFF: $DIFF_IN_DATE
#echo DIFF1: $DIFF_IN_DATE1
if [[ ($DIFF_IN_DATE -ge -120) && ($DIFF_IN_DATE1 -le 120) && (DIFF_IN_DATE1 -ge -120) ]]
then
echo File lies in Next Hour = $f
echo MOD_DATE: $MOD_DATE

#mv $PATH_SRC/$f  $PATH_DST/$f

done

For example you want files having modification date before the given date only, you may change 120 to 0 in $DIFF_IN_DATE parameter discarding the conditions of $DIFF_IN_DATE1 parameter.

Similarly if you want files having modification date 1 hour before and after given date, just replace 120 by 3600 in if CONDITION.

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

You can show an alternative text by adding alt:

<img src="my_img.png" alt="alternative text" border="0" /> 

Here is the most inefficient way to get the count in all answers. But you'll get a Dictionary that contains key-value pairs as a bonus.

string test = "key1=value1&key2=value2&key3=value3";

var keyValues = Regex.Matches(test, @"([\w\d]+)=([\w\d]+)[&$]*")
                     .Cast<Match>()
                     .ToDictionary(m => m.Groups[1].Value, m => m.Groups[2].Value);

var count = keyValues.Count - 1;

ngStyle accepts a map:

$scope.myStyle = {
    "width" : "900px",
    "background" : "red"
};

Just put your images in the assets folder refer them in your html pages or ts files with that link.

MongoDB shell version v4.2.6
Node v14.2.0

Assuming you have a Tour Model: tourModel.js

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true,
    trim: true,
  },
  createdAt: {
    type: Date,
    default: Date.now(),
  },
});
const Tour = mongoose.model('Tour', tourSchema);

module.exports = Tour;

Now you want to delete all tours at once from your MongoDB, I also providing connection code to connect with the remote cluster. I used deleteMany(), if you do not pass any args to deleteMany(), then it will delete all the documents in Tour collection.

const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');
const conStr = 'mongodb+srv://lord:<PASSWORD>@cluster0-eeev8.mongodb.net/tour-guide?retryWrites=true&w=majority';
const DB = conStr.replace('<PASSWORD>','ADUSsaZEKESKZX');
mongoose.connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true,
  })
  .then((con) => {
    console.log(`DB connection successful ${con.path}`);
  });

const deleteAllData = async () => {
  try {
    await Tour.deleteMany();
    console.log('All Data successfully deleted');
  } catch (err) {
    console.log(err);
  }
};
