This problem mainly caused by your connected username not have the access to the shell in GCE. So you use the following steps to solve this issue.

gcloud auth list

If you are using the correct login. please follow the below steps. otherwise use

gcloud auth revoke --all
gcloud auth login [your-iam-user]

and you get the token or it automatically detect the token.

gcloud compute --project "{projectid}" ssh --zone "{zone_name}" "{instance_name}" .

if you dont know this above line click to compute engine-> ssh dropdown arrow-> view google command-> copy that code and use it

Now it update your metadata and it is available in your computer's folder Users->username

~/.ssh/google_compute_engine.ppk
~/.ssh/google_compute_engine.pub

Then you create a new ppk file using puttygen and you give the username, which you want like my_work_space. Then save the publickey and privatekey in a folder.

Next step: Copy the public key data from puttygen and create new ssh key in gcloud metadata

cloud console ->compute engine->metadata->ssh key->add new item->paste the key and save it

and now return your shell commandline tool then enter

sudo chown -R my_work_space /home/my_work_space

now you connect this private key using sftp to anywhere. and it opens the files without showing the permission errors

:) happy hours.

While not in your code, another hard-to-spot error is when the % character is missing in an attempt of string formatting:

"foo %s bar %s coffee"("blah","asdf")

but it should be:

"foo %s bar %s coffee"%("blah","asdf")

The missing % would result in the same TypeError: 'str' object is not callable.

The path to the SDK is:

C:\Users\USERNAME\AppData\Local\Android\sdk

This can be used in Eclipse after you replace USERNAME with your Windows user name.

Service Events: Components can subscribe to service events. For example, two sibling components can subscribe to the same service event and respond by modifying their respective models. More on this below.

But make sure to unsubscribe to that on destroy of the parent component.

Solution to the problem

as mentioned by Uberfuzzy [ real cause of problem ]

If you look at the PHP constant [PATH_SEPARATOR][1], you will see it being ":" for you.

If you break apart your string ".:/usr/share/pear:/usr/share/php" using that character, you will get 3 parts

• . (this means the current directory your code is in)
• /usr/share/pear
• /usr/share/ph

Any attempts to include()/require() things, will look in these directories, in this order.

It is showing you that in the error message to let you know where it could NOT find the file you were trying to require()

That was the cause of error.

Now coming to solution

1. Step 1 : Find you php.ini file using command php --ini ( in my case : /etc/php5/cli/php.ini )
2. Step 2 : find include_path in vi using esc then press /include_path then enter
3. Step 3 : uncomment that line if commented and include your server directory, your path should look like this include_path = ".:/usr/share/php:/var/www/<directory>/"
4. Step 4 : Restart apache sudo service apache2 restart

This is it. Hope it helps.

Span is completely non-semantic. It has no meaning, and serves merely as an element for cosmetic effects.

Paragraphs have semantic meaning - they tell a machine (like a browser or a screen reader) that the content they encapsulate is a block of text, and has the same meaning as a paragraph of text in a book.

With the Material Components library you can customize the TextInputLayout the hint text color using:

• In the layout:

  • app:hintTextColor attribute : the color of the label when it is collapsed and the text field is active
  • android:textColorHint attribute: the color of the label in all other text field states (such as resting and disabled)

Something like:

<com.google.android.material.textfield.TextInputLayout
     app:hintTextColor="@color/mycolor"
     android:textColorHint="@color/text_input_hint_selector"
     .../>

On Arch Linux, the following works really great (should work on all systemd-based distros):

Create a systemd user service, by putting the following to ~/.config/systemd/user/ssh-agent.service:

[Unit]
Description=SSH key agent

[Service]
Type=simple
Environment=SSH_AUTH_SOCK=%t/ssh-agent.socket
ExecStart=/usr/bin/ssh-agent -D -a $SSH_AUTH_SOCK

[Install]
WantedBy=default.target

Setup shell to have an environment variable for the socket (.bash_profile, .zshrc, ...):

export SSH_AUTH_SOCK="$XDG_RUNTIME_DIR/ssh-agent.socket"

Enable the service, so it'll be started automatically on login, and start it:

systemctl --user enable ssh-agent
systemctl --user start ssh-agent

Add the following configuration setting to your local ssh config file ~/.ssh/config (this works since SSH 7.2):

AddKeysToAgent  yes

This will instruct the ssh client to always add the key to a running agent, so there's no need to ssh-add it beforehand.

This seems very easy:

>>> hash = "355879ACB6"
>>> hash = hash[:4] + '-' + hash[4:]
>>> print hash
3558-79ACB6

However if you like something like a function do as this:

def insert_dash(string, index):
    return string[:index] + '-' + string[index:]

print insert_dash("355879ACB6", 5)

A solution that works for me :

HTML

<div class="website_title"><span>My Website Title Here</span></div>

CSS

.website_title {
    background-image: url('../images/home.png');
    background-repeat: no-repeat;
    height: 18px;
    width: 16px;
}

.website_title span {
    visibility: hidden;
}

This did the trick for me:

  var domain = '{{ DOMAIN }}'; // www.example.com or dev.example.com
  var domain_index =  window.location.href.indexOf(domain);
  var long_app_name = window.location.href.slice(domain_index+domain.length+1); 
  // this turns http://www.example.com/whatever/whatever to whatever/whatever
  app_name = long_app_name.slice(0, long_app_name.indexOf('/')); 
  //now you are left off with just the first whatever which is usually your app name

then you use jquery(works with angular too) to add class active

$('nav a[href*="' + app_name+'"]').closest('li').addClass('active');

and of course the css:

.active{background:red;}

this works if you have your html like this:

<ul><li><a href="/ee">ee</a></li><li><a href="/dd">dd</a></li></ul>

this will atumatically add class active using the page url and color your background to red if your in www.somesite.com/ee thaen ee is the 'app' and it will be active

If you want one line:

list_of_dict = [{} for i in range(list_len)]

You can also use named arguments which are optional and can be given in any order.

Set namedArguments = WScript.Arguments.Named

Here's a little helper function:

Function GetNamedArgument(ByVal argumentName, ByVal defaultValue)
  If WScript.Arguments.Named.Exists(argumentName) Then
    GetNamedArgument = WScript.Arguments.Named.Item(argumentName) 
  Else  
    GetNamedArgument = defaultValue
  End If
End Function

Example VBS:

'[test.vbs]
testArg = GetNamedArgument("testArg", "-unknown-")
wscript.Echo now &": "& testArg

Example Usage:

test.vbs /testArg:123

When I tried to make ObjectMapper primary in spring boot 2.0.6 I got errors So I modified the one that spring boot created for me

You may also want to read "Why getter and setter methods are evil":

Though getter/setter methods are commonplace in Java, they are not particularly object oriented (OO). In fact, they can damage your code's maintainability. Moreover, the presence of numerous getter and setter methods is a red flag that the program isn't necessarily well designed from an OO perspective.

This article explains why you shouldn't use getters and setters (and when you can use them) and suggests a design methodology that will help you break out of the getter/setter mentality.

You can get something suitable for that purpose with:

id(self)

I also don't under stand what the "-" means after the 200 140 section of the log

That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)

This worked for me:
from xcode, Window -> Devices & Simulators, right click on your phone(s), Unpair.
Then re-connect everything, build, done.

JSON is just a subset of JavaScript. But eval evaluates the full JavaScript language and not just the subset that’s JSON.

You can cast it to an intptr_t type. It's an int type guaranteed to be big enough to contain a pointer. Use #include <cstdint> to define it.

To increase the amount of memory allocated to R you can use memory.limit

memory.limit(size = ...)

Or

memory.size(max = ...)

About the arguments

• size - numeric. If NA report the memory limit, otherwise request a new limit, in Mb. Only values of up to 4095 are allowed on 32-bit R builds, but see ‘Details’.
• max - logical. If TRUE the maximum amount of memory obtained from the OS is reported, if FALSE the amount currently in use, if NA the memory limit.

You can't but what if you set expire time to now + 100 years ?

I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.

Here's an example call, using Quandl-api download in csv

example:

https://www.quandl.com/api/v1/datasets/WIKI/AAPL.csv?column=4&sort_order=asc&collapse=quarterly&trim_start=2012-01-01&trim_end=2013-12-31

They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).

Seeing as I've just voted a recent question as a duplicate and pointed in this direction . . .

A couple more - in SQL*Plus - SET AUTOTRACE ON - will give explain plan and statistics for each statement executed.

TOAD also allows for client side profiling.

The disadvantage of both of these is that they only tell you the execution plan for the statement, but not how the optimiser arrived at that plan - for that you will need lower level server side tracing.

Another important one to understand is Statspack snapshots - they are a good way for looking at the performance of the database as a whole. Explain plan, etc, are good at finding individual SQL statements that are bottlenecks. Statspack is good at identifying the fact your problem is that a simple statement with a good execution plan is being called 1 million times in a minute.

I wrote the code below that lists all objects where a given keyword will be found. Formally speaking it is not a true 'depends on' search but it rather helps locating where a keyword is used in Stored procedures, Views, Triggers and Functions. Useful if you are using dynamic SQL.

select name, type_desc,create_date,modify_date 
from sys.all_objects o
inner join sys.all_sql_modules m on m.object_id = o.object_id
where definition like '%tableName %'

It’s easy; just do the following:

rvm implode

or

rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files:

• ~/.bashrc
• ~/.bash_profile
• ~/.profile

And maybe others depending on whatever shell you’re using.

An unmodifiable map may still change. It is only a view on a modifiable map, and changes in the backing map will be visible through the unmodifiable map. The unmodifiable map only prevents modifications for those who only have the reference to the unmodifiable view:

Map<String, String> realMap = new HashMap<String, String>();
realMap.put("A", "B");

Map<String, String> unmodifiableMap = Collections.unmodifiableMap(realMap);

// This is not possible: It would throw an 
// UnsupportedOperationException
//unmodifiableMap.put("C", "D");

// This is still possible:
realMap.put("E", "F");

// The change in the "realMap" is now also visible
// in the "unmodifiableMap". So the unmodifiableMap
// has changed after it has been created.
unmodifiableMap.get("E"); // Will return "F". 

In contrast to that, the ImmutableMap of Guava is really immutable: It is a true copy of a given map, and nobody may modify this ImmutableMap in any way.

Update:

As pointed out in a comment, an immutable map can also be created with the standard API using

Map<String, String> immutableMap = 
    Collections.unmodifiableMap(new LinkedHashMap<String, String>(realMap)); 

This will create an unmodifiable view on a true copy of the given map, and thus nicely emulates the characteristics of the ImmutableMap without having to add the dependency to Guava.

Expressions:

• Expressions are formed by combining objects and operators.
• An expression has a value, which has a type.
• Syntax for a simple expression:<object><operator><object>

2.0 + 3 is an expression which evaluates to 5.0 and has a type float associated with it.

Statements

Statements are composed of expression(s). It can span multiple lines.

The following line of code will swap the first two characters in str:

return str.charAt(1) + str.charAt(0) + str.substring(2);

Let's say we need to use the class Classname that is contained in the jar file org.example.jar

And your source is in the file mysource.java Like this:

import org.example.Classname;

public class mysource {
    public static void main(String[] argv) {
    ......
   }
}

First, as you see, in your code you have to import the classes. To do that you need import org.example.Classname;

Second, when you compile the source, you have to reference the jar file.

Please note the difference in using : and ; while compiling

• If you are under a unix like operating system:

  javac -cp '.:org.example.jar' mysource.java
  

• If you are under windows:

  javac -cp .;org.example.jar mysource.java
  

After this, you obtain the bytecode file mysource.class

Now you can run this :

• If you are under a unix like operating system:

  java -cp '.:org.example.jar' mysource
  

• If you are under windows:

  java -cp .;org.example.jar mysource
  

it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

Most of the examples here will match on 999.999.999.999 which is not technically a valid IP address.

The following will match on only valid IP addresses (including network and broadcast addresses).

grep -E -o '(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)' file.txt

Omit the -o if you want to see the entire line that matched.

With a more recent version of docker, this could be done with docker-compose and its extra_hosts directive

Add hostname mappings.
Use the same values as the docker run client --add-host parameter (which should already be available for docker 1.8).

extra_hosts:
 - "somehost:162.242.195.82"
 - "otherhost:50.31.209.229"

In short: modify /etc/hosts of your container when running it, instead of when building it.

With Docker 17.x+, you have a docker build --add-host mentioned below, but, as commented in issue 34078 and in this answer:

The --add-host feature during build is designed to allow overriding a host during build, but not to persist that configuration in the image.

The solutions mentioned do refer the docker-compose I was suggesting above:

• Run an internal DNS; you can set the default DNS server to use in the daemon; that way every container started will automatically use the configured DNS by default

• Use docker compose and provide a docker-compose.yml to your developers.
  The docker compose file allows you to specify all the options that should be used when starting a container, so developers could just docker compose up to start the container with all the options they need to set.

This works for me!

<label for="reason">Reason:</label>
<select name="reason" size="1" id="name" >
    <option value="NG" selected="SELECTED"><?php if (!(strcmp("NG", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>Selection a reason below</option>
    <option value="General"<?php if (!(strcmp("General", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>General Question</option>
    <option value="Account"<?php if (!(strcmp("Account", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Account Question</option>
    <option value="Other"<?php if (!(strcmp("Other", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Other</option>

</select>

We can try this

$scope.$apply(function() {
    $scope.step1 = true;
    //scope.list2.length = 0;
});

EDIT: Realised i should really bring the addition and subtraction out seperately aswell to make it a little bit more BODMAS compliant.

Big thanks to Rajesh Jinaga for his Stack based approach. I found it really useful for my needs. The following code is a slight modification of Rajesh's method, which processes divisions first, then multiplications, then finishes up with addition and subtraction. It will also allow the use of booleans in the expressions, where true is treated as 1 and false 0. allowing the use of boolean logic in expressions.

public static double Evaluate(string expr)
    {
        expr = expr.ToLower();
        expr = expr.Replace(" ", "");
        expr = expr.Replace("true", "1");
        expr = expr.Replace("false", "0");

        Stack<String> stack = new Stack<String>();

        string value = "";
        for (int i = 0; i < expr.Length; i++)
        {
            String s = expr.Substring(i, 1);
            // pick up any doublelogical operators first.
            if (i < expr.Length - 1)
            {
                String op = expr.Substring(i, 2);
                if (op == "<=" || op == ">=" || op == "==")
                {
                    stack.Push(value);
                    value = "";
                    stack.Push(op);
                    i++;
                    continue;
                }
            }

I know there is likely to be a cleaner way of doing it, thought id just share the first look at it in case anyone finds it usefull.

If the above solutions are not working just delete this entire line from XML

android:src="@drawable/image"

& only try

imageView.setBackgroundResource(R.drawable.image);

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

The url template tag will pass the parameter as a string and not as a function reference to reverse(). The simplest way to get this working is adding a name to the view:

url(r'^/logout/' , logout_view, name='logout_view')

To put it simply, you don't use generate inside an always process, you use generate to create a parametrized process or instantiate particular modules, where you can combine if-else or case. So you can move this generate and crea a particular process or an instantiation e.g.,

module #(
parameter XLEN = 64,
parameter USEIP = 0
)
(
 input clk,
input rstn,
input [XLEN-1:0] opA,
input [XLEN-1:0] opB,
input [XLEN-1:0] opR,
input en
);

generate 
case(USEIP)
0:begin
always @(posedge clk or negedge rstn)
begin
if(!rstn)
begin
 opR <= '{default:0};
end
else
begin
if(en)
 opR <= opA+opB;
else
opR <= '{default:0};
end
end
end
1:begin
  superAdder #(.XLEN(XLEN)) _adder(.clk(clk),.rstm(rstn), .opA(opA), .opB(opB), .opR(opR), .en(en));
end
endcase

endmodule

There are lots of solutions:

b = Arrays.copyOf(a, a.length);

Which allocates a new array, copies over the elements of a, and returns the new array.

Or

b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);

Which copies the source array content into a destination array that you allocate yourself.

Or

b = a.clone();

which works very much like Arrays.copyOf(). See this thread.

Or the one you posted, if you reverse the direction of the assignment in the loop:

b[i] = a[i]; // NOT a[i] = b[i];

Found this question searching on Google. This will return the first child of a element with class container, regardless as to what type the child is.

.container > *:first-child
{
}

Use this: For example:

select * from ACCOUNTS_DETAILS
where ACCOUNT_ID=1001
union
select * from ACCOUNTS_DETAILS
where ACCOUNT_ID=1002

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

You also can use graceful restart the apache server with service apache2 reload or apachectl -k graceful. As the apache doc says:

The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately.

def time_to_sec(time):
    sep = ','
    rest = time.split(sep, 1)[0]
    splitted = rest.split(":")
    emel = len(splitted) - 1
    i = 0
    summa = 0
    for numb in splitted:
        szor = 60 ** (emel - i)
        i += 1
        summa += int(numb) * szor
    return summa

In short, always prefer initialization lists when possible. 2 reasons:

• If you do not mention a variable in a class's initialization list, the constructor will default initialize it before entering the body of the constructor you've written. This means that option 2 will lead to each variable being written to twice, once for the default initialization and once for the assignment in the constructor body.

• Also, as mentioned by mwigdahl and avada in other answers, const members and reference members can only be initialized in an initialization list.

Also note that variables are always initialized on the order they are declared in the class declaration, not in the order they are listed in an initialization list (with proper warnings enabled a compiler will warn you if a list is written out of order). Similarly, destructors will call member destructors in the opposite order, last to first in the class declaration, after the code in your class's destructor has executed.

The HumanFriendly project helps with this.

import humanfriendly
humanfriendly.format_size(1024)

The above code will give 1KB as answer.
Examples can be found here.

To obtain all the rows that contains an empty cell in in a particular column.

DF_new_row=DF_raw.loc[DF_raw['columnname']=='']

This will give the subset of DF_raw, which satisfy the checking condition.

Don't forget to inject $location into controller.

If you have Perl installed, you could use ack, available at http://beyondgrep.com/.

See the following project on GitHub: https://github.com/ghuntley/csharp-mssql-connectivity-tester

try
{
    Console.WriteLine("Connecting to: {0}", AppConfig.ConnectionString);
    using (var connection = new SqlConnection(AppConfig.ConnectionString))
    {
        var query = "select 1";
        Console.WriteLine("Executing: {0}", query);

        var command = new SqlCommand(query, connection);

        connection.Open();
        Console.WriteLine("SQL Connection successful.");

        command.ExecuteScalar();
        Console.WriteLine("SQL Query execution successful.");
    }
}
catch (Exception ex)
{
    Console.WriteLine("Failure: {0}", ex.Message);
}

Your code works just fine. It's most likely the window thats not focused. I use a similar function to close iframe boxes etc.

$(document).ready(function(){

    // Set focus
    setTimeout('window.focus()',1000);

});

$(document).keypress(function(e) {

    // Enable esc
    if (e.keyCode == 27) {
      parent.document.getElementById('iframediv').style.display='none';
      parent.document.getElementById('iframe').src='/views/view.empty.black.html';
    }

});

Update array field in multiple documents in mongo db.

Use $pull or $push with update many query to update array elements in mongoDb.

Notification.updateMany(
    { "_id": { $in: req.body.notificationIds } },
    {
        $pull: { "receiversId": req.body.userId }
    }, function (err) {
        if (err) {
            res.status(500).json({ "msg": err });
        } else {
            res.status(200).json({
                "msg": "Notification Deleted Successfully."
            });
        }
    });

moment(timestamp).format('''any format''')

>>> j = '{"action": "print", "method": "onData", "data": "Madan Mohan"}'
>>> import json

By default, Valgrind writes its output to stderr. So you need to do something like:

valgrind a.out > log.txt 2>&1

Alternatively, you can tell Valgrind to write somewhere else; see http://valgrind.org/docs/manual/manual-core.html#manual-core.comment (but I've never tried this).

For Swift 3.0 use the following code:

    UIGraphicsBeginImageContext(self.view.frame.size)
    UIImage(named: "bg.png")?.drawAsPattern(in: self.view.bounds)
    let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    self.view.backgroundColor = UIColor(patternImage: image)

It means you allow every (*) user-agent/crawler to access the root (/) of your site. You're okay.

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

Works 100% without any problem and will not redirect to another page...I tried just copying this and changing your message

// Initialize a string and write Your message it will work
string message = "Helloq World";
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("alert('");
sb.Append(message);
sb.Append("');");
ClientScript.RegisterOnSubmitStatement(this.GetType(), "alert", sb.ToString());

I am using script to get empty space in each file:

Create Table ##temp
(
    DatabaseName sysname,
    Name sysname,
    physical_name nvarchar(500),
    size decimal (18,2),
    FreeSpace decimal (18,2)
)   
Exec sp_msforeachdb '
Use [?];
Insert Into ##temp (DatabaseName, Name, physical_name, Size, FreeSpace)
    Select DB_NAME() AS [DatabaseName], Name,  physical_name,
    Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) as nvarchar) Size,
    Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) -
        Cast(FILEPROPERTY(name, ''SpaceUsed'') * 8.0/1024.0 as decimal(18,2)) as nvarchar) As FreeSpace
    From sys.database_files

Select * From ##temp
drop table ##temp

Size is expressed in KB.

To change into another directory use WORKDIR. All the RUN, CMD and ENTRYPOINT commands after WORKDIR will be executed from that directory.

RUN git clone XYZ 
WORKDIR "/XYZ"
RUN make

You need to break;, throw, goto, or return from each of your case labels. In a loop you may also continue.

        switch (searchType)
        {
            case "SearchBooks":
                Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
                break;

            case "SearchAuthors":
                Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
                break;
        }

The only time this isn't true is when the case labels are stacked like this:

 case "SearchBooks": // no code inbetween case labels.
 case "SearchAuthors":
    // handle both of these cases the same way.
    break;

Try this simple code.

1. Components side code: to get both body and header property. Here there's a token in body and Authorization in the header.

loginUser() {
    this.userService.loginTest(this.loginCred).
    subscribe(res => {
        let output1 = res;
        console.log(output1.body.token);
        console.log(output1.headers.get('Authorization'));
    })
}

2. Service side code: sending login data in the body and observe the response in Observable any which be subscribed in the component side.

loginTest(loginCred: LoginParams): Observable<any> {
    const header1= {'Content-Type':'application/json',};
    const body =  JSON.stringify(loginCred);
    return this.http.post<any>(this.baseURL+'signin',body,{
        headers: header1,
        observe: 'response',
        responseType: 'json'
    });
}

I don't think there's any need of writing this much big codes.

I've just installed angular-print bower package and all is set to go.

Mine is working awesome .

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

I created a little example that shows 3 different and simple ways of dealing with threads. I hope it will help you find the right approach to your problem.

Probably the best solution is to look at the threeparttable/threeparttablex packages.

I have faced same problem with maven dependencies, eg: unfortunetly your maven dependencies deleted from your buildpath,then you people get lot of exceptions,if you follow below process you can easily resolve this issue.

Well, running example:

WARNING! NEVER DO THIS AT HOME/WORK! Only in classroom ;)

Use semaphores, shared variables, etc. to avoid rush conditions.

from threading import Thread
import time

a = 0  # global variable


def thread1(threadname):
    global a
    for k in range(100):
        print("{} {}".format(threadname, a))
        time.sleep(0.1)
        if k == 5:
            a += 100


def thread2(threadname):
    global a
    for k in range(10):
        a += 1
        time.sleep(0.2)


thread1 = Thread(target=thread1, args=("Thread-1",))
thread2 = Thread(target=thread2, args=("Thread-2",))

thread1.start()
thread2.start()

thread1.join()
thread2.join()

and the output:

Thread-1 0
Thread-1 1
Thread-1 2
Thread-1 2
Thread-1 3
Thread-1 3
Thread-1 104
Thread-1 104
Thread-1 105
Thread-1 105
Thread-1 106

Thread-1 110
Thread-1 110
Thread-1 110
Thread-1 110
Thread-1 110
Thread-1 110
Thread-1 110

If the timing were right, the a += 100 operation would be skipped:

Processor executes at T a+100 and gets 104. But it stops, and jumps to next thread Here, At T+1 executes a+1 with old value of a, a == 4. So it computes 5. Jump back (at T+2), thread 1, and write a=104 in memory. Now back at thread 2, time is T+3 and write a=5 in memory. Voila! The next print instruction will print 5 instead of 104.

VERY nasty bug to be reproduced and caught.

Use Timer for this

   private System.Windows.Forms.Timer timer1; 
   private int counter = 60;
   private void btnStart_Click_1(object sender, EventArgs e)
   {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = 1000; // 1 second
        timer1.Start();
        lblCountDown.Text = counter.ToString();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        counter--;
        if (counter == 0)
            timer1.Stop();
        lblCountDown.Text = counter.ToString();
    }

Just in case someone needs to parameterize hive query via cli.

For eg:

hive_query.sql

SELECT * FROM foo WHERE day >= '${hivevar:CURRENT_DATE}'

Now execute above sql file from cli:

hive --hivevar CURRENT_DATE="2012-09-16" -f hive_query.sql

String link = driver.findElement(By.linkText(linkText)).getAttribute("href")

This will give you the link the element is pointing to.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict
>>>

sorted=($(echo ${array[@]} | tr " " "\n" | sort))

In the spirit of bash / linux, I would pipe the best command-line tool for each step. sort does the main job but needs input separated by newline instead of space, so the very simple pipeline above simply does:

Echo array content --> replace space by newline --> sort

$() is to echo the result

($()) is to put the "echoed result" in an array

Note: as @sorontar mentioned in a comment to a different question:

The sorted=($(...)) part is using the "split and glob" operator. You should turn glob off: set -f or set -o noglob or shopt -op noglob or an element of the array like * will be expanded to a list of files.

yes! you should be using pip as your python package manager ( http://pypi.python.org/pypi/pip )

with pip installed packages, you can do a

pip freeze

and it will list all installed packages. You should probably also be using virtualenv and virtualenvwrapper. When you start a new project, you can do

mkvirtualenv my_new_project

and then (inside that virtualenv), do

pip install all_your_stuff

This way, you can workon my_new_project and then pip freeze to see which packages are installed for that virtualenv/project.

for example:

?  ~  mkvirtualenv yo_dude
New python executable in yo_dude/bin/python
Installing setuptools............done.
Installing pip...............done.

virtualenvwrapper.user_scripts creating /Users/aaylward/dev/virtualenvs/yo_dude/bin/postactivate
virtualenvwrapper.user_scripts creating /Users/aaylward/dev/virtualenvs/yo_dude/bin/get_env_details

or if you have a python package with a requirements.pip file,

mkvirtualenv my_awesome_project
pip install -r requirements.pip
pip freeze

will do the trick

Check if you're not incrementing with some variable that its value is an empty string like ''.

Example:

$total = '';
$integers = range(1, 5);

foreach($integers as $integer) {
    $total += $integer;
}

I just found this on the Internet. This should work:

DWORD random = ((min) + rand()/(RAND_MAX + 1.0) * ((max) - (min) + 1));

iOS Simulator > Menu Bar > Debug > Open System Log

Old ways:

iOS Simulator prints its logs directly to stdout, so you can see the logs mixed up with system logs.

Open the Terminal and type: tail -f /var/log/system.log

Then run the simulator.

EDIT:

This stopped working on Mavericks/Xcode 5. Now you can access the simulator logs in its own folder: ~/Library/Logs/iOS Simulator/<sim-version>/system.log

You can either use the Console.app to see this, or just do a tail (iOS 7.0.3 64 bits for example):

tail -f ~/Library/Logs/iOS\ Simulator/7.0.3-64/system.log

EDIT 2:

They are now located in ~/Library/Logs/CoreSimulator/<simulator-hash>/system.log

tail -f ~/Library/Logs/CoreSimulator/<simulator-hash>/system.log

Maybe this helps someone:

git tag 0.0.1                    # creates tag locally     
git push origin 0.0.1            # pushes tag to remote

git tag --delete 0.0.1           # deletes tag locally    
git push --delete origin 0.0.1   # deletes remote tag

Why not use order by asc limit 1 and the reverse, order by desc limit 1?

You can do it with regular JavaScript this way:

document.getElementById('h1_id').innerHTML = 'h1 content here';

Here is the doc for getElementById and the innerHTML property.

The innerHTML property description:

A DOMString containing the HTML serialization of the element's descendants. Setting the value of innerHTML removes all of the element's descendants and replaces them with nodes constructed by parsing the HTML given in the string htmlString.

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

Cheers!

Not really, no.

Java doesn't have pointers. If you really wanted you could try to emulate them by building around something like reflection, but it would have all of the complexity of pointers with none of the benefits.

Java doesn't have pointers because it doesn't need them. What kind of answers were you hoping for from this question, i.e. deep down did you hope you could use them for something or was this just curiousity?

Quite simply the number is the precision of the timestamp, the fraction of a second held in the column:

SQL> create table t23
  2  (ts0 timestamp(0)
  3   , ts3 timestamp(3)
  4  , ts6 timestamp(6)
  5  )
  6  /

Table created.

SQL> insert into t23 values (systimestamp, systimestamp, systimestamp)
  2  /

1 row created.

SQL> select * from t23

If we don't specify a precision then the timestamp defaults to six places.

SQL> alter table t23 add ts_def timestamp;

Table altered.

SQL> update t23

Note that I'm running on Linux so my TIMESTAMP column actually gives me precision to six places i.e. microseconds. This would also be the case on most (all?) flavours of Unix. On Windows the limit is three places i.e. milliseconds. (Is this still true of the most modern flavours of Windows - citation needed).

As might be expected, the documentation covers this. Find out more.

"when you create timestamp(9) this gives you nanos right"

Only if the OS supports it. As you can see, my OEL appliance does not:

Table altered.

SQL> update t23 set ts_nano = systimestamp(9)

I needed to copy all .md files from one directory into another, so here is what I did.

for i in **/*.md;do mkdir -p ../docs/"$i" && rm -r ../docs/"$i" && cp "$i" "../docs/$i" && echo "$i -> ../docs/$i"; done

Which is pretty hard to read, so lets break it down.

first cd into the directory with your files,

for i in **/*.md; for each file in your pattern

mkdir -p ../docs/"$i"make that directory in a docs folder outside of folder containing your files. Which creates an extra folder with the same name as that file.

rm -r ../docs/"$i" remove the extra folder that is created as a result of mkdir -p

cp "$i" "../docs/$i" Copy the actual file

echo "$i -> ../docs/$i" Echo what you did

; done Live happily ever after

ES6 approach...

Imagine you have this object below:

const developers = {
  1: {
   id: 1,
   name: "Brendan", 
   family: "Eich"
  },
  2: {
   id: 2,
   name: "John", 
   family: "Resig"
  },  
  3: {
   id: 3,
   name: "Alireza", 
   family: "Dezfoolian"
 }
};

Create a function:

const filterObject = (obj, filter, filterValue) => 
   Object.keys(obj).reduce((acc, val) => 
   (obj[val][filter] === filterValue ? acc : {
       ...acc,
       [val]: obj[val]
   }                                        
), {});

And call it:

filterObject(developers, "name", "Alireza");

and will return:

{
  1: {
  id: 1,
  name: "Brendan", 
  family: "Eich"
  },
  2: {
   id: 2,
   name: "John", 
   family: "Resig"
  }
}

I wanted to be able to specify which tab was shown by class rather than index as I thought it made for a robust solution that was less dependant on how you wire up IB. I didn't find either Disco's or Joped's solutions to work so i created this method:

-(void)setTab:(Class)class{
    int i = 0;
    for (UINavigationController *controller in self.tabBarContontroller.viewControllers){
        if ([controller isKindOfClass:class]){
            break;
        }
        i++;
    }
    self.tabBarContontroller.selectedIndex = i;
}

you call it like this:

[self setTab:[YourClass class]];

Hope this is helpful to someone

One alternative is to represent your 2D array as a 1D array. This can make element-wise operations more efficient. You should probably wrap it in a class that would also contain width and height.

Another alternative is to represent a 2D array as an std::vector<std::vector<int> >. This will let you use STL's algorithms for array arithmetic, and the vector will also take care of memory management for you.

For Python 2 give execfile a try. (See other answers for Python 3)

execfile('file.py')

Example usage:
Let's use "copy con" to quickly create a small script file...

C:\junk>copy con execfile_example.py
a = [9, 42, 888]
b = len(a)
^Z
        1 file(s) copied.

...and then let's load this script like so:

C:\junk>\python27\python
Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> execfile('execfile_example.py')
>>> a
[9, 42, 888]
>>> b
3
>>>

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

You can easily do with first you can make the div flex and apply justify content right or left and your problem is solved.

<div style="display: flex;padding-bottom: 8px;justify-content: flex-end;">_x000D_
     <button style="font-weight: bold;outline: none;background-color: #2764ff;border-radius: 3px;margin-left: 12px;border: none;padding: 3px 6px;color: white;text-align: center;font-family: 'Open Sans', sans-serif;text-decoration: none;margin-right: 14px;">Sense</button>_x000D_
    </div>

Python's implementation follows the IEEE-754 standard pretty well, which you can use as a guidance, but it relies on the underlying system it was compiled on, so platform differences may occur. Recently¹, a fix has been applied that allows "infinity" as well as "inf", but that's of minor importance here.

The following sections equally well apply to any language that implements IEEE floating point arithmetic correctly, it is not specific to just Python.

Comparison for inequality

When dealing with infinity and greater-than > or less-than < operators, the following counts:

• any number including +inf is higher than -inf
• any number including -inf is lower than +inf
• +inf is neither higher nor lower than +inf
• -inf is neither higher nor lower than -inf
• any comparison involving NaN is false (inf is neither higher, nor lower than NaN)

Comparison for equality

When compared for equality, +inf and +inf are equal, as are -inf and -inf. This is a much debated issue and may sound controversial to you, but it's in the IEEE standard and Python behaves just like that.

Of course, +inf is unequal to -inf and everything, including NaN itself, is unequal to NaN.

Calculations with infinity

Most calculations with infinity will yield infinity, unless both operands are infinity, when the operation division or modulo, or with multiplication with zero, there are some special rules to keep in mind:

• when multiplied by zero, for which the result is undefined, it yields NaN
• when dividing any number (except infinity itself) by infinity, which yields 0.0 or -0.0².
• when dividing (including modulo) positive or negative infinity by positive or negative infinity, the result is undefined, so NaN.
• when subtracting, the results may be surprising, but follow common math sense:
  • when doing inf - inf, the result is undefined: NaN;
  • when doing inf - -inf, the result is inf;
  • when doing -inf - inf, the result is -inf;
  • when doing -inf - -inf, the result is undefined: NaN.
• when adding, it can be similarly surprising too:
  • when doing inf + inf, the result is inf;
  • when doing inf + -inf, the result is undefined: NaN;
  • when doing -inf + inf, the result is undefined: NaN;
  • when doing -inf + -inf, the result is -inf.
• using math.pow, pow or ** is tricky, as it doesn't behave as it should. It throws an overflow exception when the result with two real numbers is too high to fit a double precision float (it should return infinity), but when the input is inf or -inf, it behaves correctly and returns either inf or 0.0. When the second argument is NaN, it returns NaN, unless the first argument is 1.0. There are more issues, not all covered in the docs.

• math.exp suffers the same issues as math.pow. A solution to fix this for overflow is to use code similar to this:

  try:
      res = math.exp(420000)
  except OverflowError:
      res = float('inf')
  

Notes

Note 1: as an additional caveat, that as defined by the IEEE standard, if your calculation result under-or overflows, the result will not be an under- or overflow error, but positive or negative infinity: 1e308 * 10.0 yields inf.

Note 2: because any calculation with NaN returns NaN and any comparison to NaN, including NaN itself is false, you should use the math.isnan function to determine if a number is indeed NaN.

Note 3: though Python supports writing float('-NaN'), the sign is ignored, because there exists no sign on NaN internally. If you divide -inf / +inf, the result is NaN, not -NaN (there is no such thing).

Note 4: be careful to rely on any of the above, as Python relies on the C or Java library it was compiled for and not all underlying systems implement all this behavior correctly. If you want to be sure, test for infinity prior to doing your calculations.

¹) Recently means since version 3.2.
²) Floating points support positive and negative zero, so: x / float('inf') keeps its sign and -1 / float('inf') yields -0.0, 1 / float(-inf) yields -0.0, 1 / float('inf') yields 0.0 and -1/ float(-inf) yields 0.0. In addition, 0.0 == -0.0 is true, you have to manually check the sign if you don't want it to be true.

\n must be in double quotes!

echo "hello\nworld";

Output

hello
world

A nice way around this is to use PHP as a more of a templating language

<p>
    Hello <span><?php echo $world ?></span>
</p>

Output

<p>
    Hello <span>Planet Earth</span>
</p>

Notice, all newlines are kept in tact!

I'm aware this is an old question, but I stumbled across it while trying to find an answer myself.

The answer that mentions the online json-pojo generator (jsongen) is good, but I needed something I could run on the command line and tweak more.

So I wrote a very hacky ruby script to take a sample JSON file and generate POJOs from it. It has a number of limitations (for example, it doesn't deal with fields that match java reserved keywords) but it does enough for many cases.

The code generated, by default, annotates for use with Jackson, but this can be turned off with a switch.

You can find the code on github: https://github.com/wotifgroup/json2pojo

use the built in float() function in a list comprehension.

A2 = [float(v.replace('"','').strip()) for v in A1]

You need to create a new Jpanel object in the Board constructor. for example

public Board(){
    JPanel pane = new JPanel();
    pane.setBackground(Color.ORANGE);// sets the background to orange
} 

In my case it was the ErrorLog directive in httpd.conf. Just accidently noticed it already after I gave up. Decided to share the discovery ) Now I know where to find the 500-errors.

The 2 main reason why you might want to prefer Mongo are

• Flexibility in schema design (JSON type document store).
• Scalability - Just add up nodes and it can scale horizontally quite well.

It is suitable for big data applications. RDBMS is not good for big data.

removing temp files, and did you restart the computer or stop the MySQL service? That's the error message you get when there isn't a MySQL server running.

This is the correct answer. It worked!!

You may do a session and place it:

// Start session
session_start();

// Check do the person logged in
if($_SESSION['username']==NULL){
    // Haven't log in
    echo "You haven't log in";
}else{
    // Logged in
    echo "Successfully logged in!";
}

Note: you must make a form which contain $_SESSION['username'] = $login_input_username;

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

Try using below code:

<button title="button title" class="action primary tocart" onclick=" window.open('http://www.google.com', '_blank'); return false;">Google</button>

Here, the window.open with _blank as second argument of window.open function will open the link in new tab.

And by the use of return false we can remove/cancel the default behavior of the button like submit.

I found solution how to use $location.search() to get parameter from URL

first in URL u need put syntax " # " before parameter like this example

"http://www.example.com/page#?key=value"

and then in your controller u put $location in function and use $location.search() to get URL parameter for

.controller('yourController', ['$scope', function($scope, $location) {

     var param1 = $location.search().param1; //Get parameter from URL

}]);

The terminal uses environment variables to determine which character set to use, therefore you can determine it by looking at those variables:

echo $LC_CTYPE

or

echo $LANG

Actually, curl has an option explicitly for this: --resolve

Instead of curl -H 'Host: yada.com' http://127.0.0.1/something

use curl --resolve 'yada.com:80:127.0.0.1' http://yada.com/something

What's the difference, you ask?

Among others, this works with HTTPS. Assuming your local server has a certificate for yada.com, the first example above will fail because the yada.com certificate doesn't match the 127.0.0.1 hostname in the URL.

The second example works correctly with HTTPS.

In essence, passing a "Host" header via -H does hack your Host into the header set, but bypasses all of curl's host-specific intelligence. Using --resolve leverages all of the normal logic that applies, but simply pretends the DNS lookup returned the data in your command-line option. It works just like /etc/hosts should.

Note --resolve takes a port number, so for HTTPS you would use

curl --resolve 'yada.com:443:127.0.0.1' https://yada.com/something

Just in case, you are using the GMaps.js library, which makes it a bit simpler to do things like Geocoding and custom pins, here's how you solve this issue using the techniques learned from the previous answers.

var Gmap = new GMaps({
  div: '#main-map', // FYI, this setting property used to be 'el'. It didn't need the '#' in older versions
  lat: 51.044308,
  lng: -114.0630914,
  zoom: 15
});

// To access the Native Google Maps object use the .map property
if(Gmap.map) {
  // Disabling mouse wheel scroll zooming
  Gmap.map.setOptions({ scrollwheel: false });
}

While possible, it's potentially very risky - if you attempt to commit changes to the repository from 2 different locations simultaneously, you'll get a giant mess due to the file conflicts. Get a free private SVN host somewhere, or set up a repository on a server you have access to.

Edit based on a recent experience: If you have files open that are managed by Dropbox and your computer crashes, your files may be truncated to 0 bytes. If this happens to the files which manage your repository, your repository will be corrupted. If you discover this soon enough, you can use Dropbox's "recover old version" feature but you're still taking a risk.

@Francisco Goldenstein, just a minor correction. The COMMIT must be used after you set the variable, otherwise the WHILE will be executed just once:

DECLARE @Deleted_Rows INT;
SET @Deleted_Rows = 1;

WHILE (@Deleted_Rows > 0)
BEGIN
    BEGIN TRANSACTION

    -- Delete some small number of rows at a time
    DELETE TOP (10000)  LargeTable 
    WHERE readTime < dateadd(MONTH,-7,GETDATE())

    SET @Deleted_Rows = @@ROWCOUNT;

    COMMIT TRANSACTION
    CHECKPOINT -- for simple recovery model

END

First off, your code is a bit off. aes() is an argument in ggplot(), you don't use ggplot(...) + aes(...) + layers

Second, from the help file ?geom_bar:

By default, geom_bar uses stat="count" which makes the height of the bar proportion to the number of cases in each group (or if the weight aethetic is supplied, the sum of the weights). If you want the heights of the bars to represent values in the data, use stat="identity" and map a variable to the y aesthetic.

You want the second case, where the height of the bar is equal to the conversion_rate So what you want is...

data_country <- data.frame(country = c("China", "Germany", "UK", "US"), 
            conversion_rate = c(0.001331558,0.062428188, 0.052612025, 0.037800687))
ggplot(data_country, aes(x=country,y = conversion_rate)) +geom_bar(stat = "identity")

Result:

OpenID is (mainly) for identification/authentication, so that stackoverflow.com knows that I own chris.boyle.name (or wherever) and therefore that I am probably the same person who owned chris.boyle.name yesterday and earned some reputation points.

OAuth is designed for authorization to take actions on your behalf, so that stackoverflow.com (or wherever) can ask permission to, say, Tweet on your behalf automatically, without knowing your Twitter password.

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

If you are using C#3 a good tip is to create an extension method to make this even simpler. Just create a static method (preferably in a static class) like so:

public static class Extensions
{
    public static string HtmlEncode(this string s)
    {
        return HttpUtility.HtmlEncode(s);
    }
}

You can then do neat stuff like this:

string encoded = "<div>I need encoding</div>".HtmlEncode();

If You want to check only when scroll ended, in Vanilla JS, You can come up with a solution like this:

Super Super compact

var t
window.onresize = () => { clearTimeout(t) t = setTimeout(() => { resEnded() }, 500) }
function resEnded() { console.log('ended') }

All 3 possible combinations together (ES6)

var t
window.onresize = () => {
    resizing(this, this.innerWidth, this.innerHeight) //1
    if (typeof t == 'undefined') resStarted() //2
    clearTimeout(t); t = setTimeout(() => { t = undefined; resEnded() }, 500) //3
}

function resizing(target, w, h) {
    console.log(`Youre resizing: width ${w} height ${h}`)
}    
function resStarted() { 
    console.log('Resize Started') 
}
function resEnded() { 
    console.log('Resize Ended') 
}

UPDATE:

Time has changed, you can now remove (expire) TestFlight Builds as in this answer but you still cannot delete the build.

OLD:

I asked apple and here is their answer:

I understand you would like to remove a build from iTunes Connect as shown in your screenshot.

Please be advised this is expected behavior as you can remove a build from being the current build but you cannot delete it from iTunes Connect. For more information, please refer to the iTunes Connect Developer Guide: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/

So i just can't.

Or without the year:

DateTime.Now.ToString("M/dd")

@echo off

echo Type your text here.

:top

set /p boompanes=

pause

echo %boompanes%> practice.txt

hope this helps. you should change the string names(IDK what its called) and the file name

I'm afraid there's not enough information in your question to be certain about what's going on, since you haven't replied to my follow-up question, but this may be of help in any case.

That error means that projectfolder is already staged ("already exists in the index"). To find out what's going on here, try to list everything in the index under that folder with:

git ls-files --stage projectfolder

The first column of that output will tell you what type of object is in the index at projectfolder. (These look like Unix filemodes, but have special meanings in git.)

I suspect that you will see something like:

160000 d00cf29f23627fc54eb992dde6a79112677cd86c 0   projectfolder

(i.e. a line beginning with 160000), in which case the repository in projectfolder has already been added as a "gitlink". If it doesn't appear in the output of git submodule, and you want to re-add it as a submodule, you can do:

git rm --cached projectfolder

... to unstage it, and then:

git submodule add url_to_repo projectfolder

... to add the repository as a submodule.

However, it's also possible that you will see many blobs listed (with file modes 100644 and 100755), which would suggest to me that you didn't properly unstage the files in projectfolder before copying the new repository into place. If that's the case, you can do the following to unstage all of those files:

git rm -r --cached projectfolder

... and then add the submodule with:

git submodule add url_to_repo projectfolder

Yes numpy has a size function, and shape and size are not quite the same.

Input

import numpy as np
data = [[1, 2, 3, 4], [5, 6, 7, 8]]
arrData = np.array(data)

print(data)
print(arrData.size)
print(arrData.shape)

Output

[[1, 2, 3, 4], [5, 6, 7, 8]]

8 # size

(2, 4) # shape

list multiplication works.

>>> [0] * 10
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

<%= render file: 'public/404', status: 404, formats: [:html] %>

just add this to the page you want to render to the 404 error page and you are done.

The drop-down is platform-level element, you can't apply CSS to it.

You can overlay an image on top of it using CSS, and call the click event in the element beneath.

I discovered a solution to this that I haven't yet seen elsewhere. You can use a custom application object that knows if you have background tasks going, instead of trying to do this in the activity that gets destroyed and recreated on orientation change. I blogged about this in here.

I have created some sample code which creates new variables using a variety of ways that I can think of. It looks like the first 3 ways create values, and the last two create references.

package main

import "fmt"

type Config struct {
    host string
    port float64
}

func main() {
    //value
    var c1 Config
    c2 := Config{}
    c3 := *new(Config)

    //reference
    c4 := &Config{}
    c5 := new(Config)

    fmt.Println(&c1 == nil)
    fmt.Println(&c2 == nil)
    fmt.Println(&c3 == nil)
    fmt.Println(c4 == nil)
    fmt.Println(c5 == nil)

    fmt.Println(c1, c2, c3, c4, c5)
}

which outputs:

false
false
false
false
false
{ 0} { 0} { 0} &{ 0} &{ 0}

First, there are errors in your code, ie. you are missing a semicolon and a closing parenthesis in the for loop.

Then, if you are trying to append values to the view, you should use textview.appendText(), instead of .setText().

There's a similar question here: how to change text in Android TextView

var res = from s in Splitting 
          join c in Customer on s.CustomerId equals c.Id
         where c.Id == customrId
            && c.CompanyId == companyId
        select s;

Using Extension methods:

var res = Splitting.Join(Customer,
                 s => s.CustomerId,
                 c => c.Id,
                 (s, c) => new { s, c })
           .Where(sc => sc.c.Id == userId && sc.c.CompanyId == companId)
           .Select(sc => sc.s);

If you assign value 0 to item.selectedVariant it should be selected automatically. Check out sample on http://docs.angularjs.org/api/ng.directive:select which selects red color by default by simply assigning $scope.color='red'.

__func__ is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:

The identifier __func__ is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration

static const char __func__[] = "function-name";

appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function.

Note that it is not a macro and it has no special meaning during preprocessing.

__func__ was added to C++ in C++11, where it is specified as containing "an implementation-de?ned string" (C++11 §8.4.1[dcl.fct.def.general]/8), which is not quite as useful as the specification in C. (The original proposal to add __func__ to C++ was N1642).

__FUNCTION__ is a pre-standard extension that some C compilers support (including gcc and Visual C++); in general, you should use __func__ where it is supported and only use __FUNCTION__ if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__).

__PRETTY_FUNCTION__ is a gcc extension that is mostly the same as __FUNCTION__, except that for C++ functions it contains the "pretty" name of the function including the signature of the function. Visual C++ has a similar (but not quite identical) extension, __FUNCSIG__.

For the nonstandard macros, you will want to consult your compiler's documentation. The Visual C++ extensions are included in the MSDN documentation of the C++ compiler's "Predefined Macros". The gcc documentation extensions are described in the gcc documentation page "Function Names as Strings."

Simply use hr tag in HTML file and add below code in CSS file .

    hr {
       display: block;
       position: relative;
       padding: 0;
       margin: 8px auto;
       height: 0;
       width: 100%;
       max-height: 0;
       font-size: 1px;
       line-height: 0;
       clear: both;
       border: none;
       border-top: 1px solid #aaaaaa;
       border-bottom: 1px solid #ffffff;
    }

it works perfectly .

quirksmode has a good description of the 'text-overflow' property, but you may need to apply some additional properties like 'white-space: nowrap'

Whilst I'm not 100% how this will behave in a select object, it could be worth trying this first:

ALTERNATE WAY:

Click Developer Tools to inspect element. You may also use keyboard shortcuts, such as CtrlL+Shift+I, F12 (or Fn+F12), etc.

You can use the "export" solution just like what other guys have suggested. I'd like to provide you with another solution for permanent convenience: you can use any path as GOPATH when running Go commands.

Firstly, you need to download a small tool named gost : https://github.com/byte16/gost/releases . If you use ubuntu, you can download the linux version(https://github.com/byte16/gost/releases/download/v0.1.0/gost_linux_amd64.tar.gz).

Then you need to run the commands below to unpack it :

$ cd /path/to/your/download/directory 
$ tar -xvf gost_linux_amd64.tar.gz

You would get an executable gost. You can move it to /usr/local/bin for convenient use:

$ sudo mv gost /usr/local/bin

Run the command below to add the path you want to use as GOPATH into the pathspace gost maintains. It is required to give the path a name which you would use later.

$ gost add foo /home/foobar/bar     # 'foo' is the name and '/home/foobar/bar' is the path

Run any Go command you want in the format:

gost goCommand [-p {pathName}] -- [goFlags...] [goArgs...]

For example, you want to run go get github.com/go-sql-driver/mysql with /home/foobar/bar as the GOPATH, just do it as below:

$ gost get -p foo -- github.com/go-sql-driver/mysql  # 'foo' is the name you give to the path above.

It would help you to set the GOPATH and run the command. But remember that you have added the path into gost's pathspace. If you are under any level of subdirectories of /home/foobar/bar, you can even just run the command below which would do the same thing for short :

$ gost get -- github.com/go-sql-driver/mysql

gost is a Simple Tool of Go which can help you to manage GOPATHs and run Go commands. For more details about how to use it to run other Go commands, you can just run gost help goCmdName. For example you want to know more about install, just type words below in:

$ gost help install

You can also find more details in the README of the project: https://github.com/byte16/gost/blob/master/README.md

My solution to this one, which I like because it is nicely general, is as follows:

/// <summary>
/// Automagically convert known interfaces to (specific) concrete classes on deserialisation
/// </summary>
public class WithMocksJsonConverter : JsonConverter
{
    /// <summary>
    /// The interfaces I know how to instantiate mapped to the classes with which I shall instantiate them, as a Dictionary.
    /// </summary>
    private readonly Dictionary<Type,Type> conversions = new Dictionary<Type,Type>() { 
        { typeof(IOne), typeof(MockOne) },
        { typeof(ITwo), typeof(MockTwo) },
        { typeof(IThree), typeof(MockThree) },
        { typeof(IFour), typeof(MockFour) }
    };

    /// <summary>
    /// Can I convert an object of this type?
    /// </summary>
    /// <param name="objectType">The type under consideration</param>
    /// <returns>True if I can convert the type under consideration, else false.</returns>
    public override bool CanConvert(Type objectType)
    {
        return conversions.Keys.Contains(objectType);
    }

    /// <summary>
    /// Attempt to read an object of the specified type from this reader.
    /// </summary>
    /// <param name="reader">The reader from which I read.</param>
    /// <param name="objectType">The type of object I'm trying to read, anticipated to be one I can convert.</param>
    /// <param name="existingValue">The existing value of the object being read.</param>
    /// <param name="serializer">The serializer invoking this request.</param>
    /// <returns>An object of the type into which I convert the specified objectType.</returns>
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        try
        {
            return serializer.Deserialize(reader, this.conversions[objectType]);
        }
        catch (Exception)
        {
            throw new NotSupportedException(string.Format("Type {0} unexpected.", objectType));
        }
    }

    /// <summary>
    /// Not yet implemented.
    /// </summary>
    /// <param name="writer">The writer to which I would write.</param>
    /// <param name="value">The value I am attempting to write.</param>
    /// <param name="serializer">the serializer invoking this request.</param>
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

}

You could obviously and trivially convert it into an even more general converter by adding a constructor which took an argument of type Dictionary<Type,Type> with which to instantiate the conversions instance variable.

When EDMX create this time if you select stored procedured in table select option then just call store procedured using procedured name...

var num1 = 1; 
var num2 = 2; 

var result = context.proc_name(num1,num2).tolist();// list or single you get here.. using same thing you can call insert,update or delete procedured.

Use This Code

@echo off
:: Get the current directory

for /f "tokens=* delims=/" %%A in ('cd') do set CURRENT_DIR=%%A

echo CURRENT_DIR%%A 

(echo this To confirm this code works fine)

I create a uniqueId generator module (Typescript):

const uniqueId = ((): ((prefix: string) => string) => {
  let counter = 0;
  return (prefix: string): string => `${prefix}${++counter}`;
})();

export default uniqueId;

And use top module to generate unique ids:

import React, { FC, ReactElement } from 'react'
import uniqueId from '../../modules/uniqueId';

const Component: FC = (): ReactElement => {
  const [inputId] = useState(uniqueId('input-'));
  return (
    <label htmlFor={inputId}>
      <span>text</span>
      <input id={inputId} type="text" />
    </label>
  );
};     

Need some adjusts but should work for Express v4. Including those routes added with .use().

function listRoutes(routes, stack, parent){

  parent = parent || '';
  if(stack){
    stack.forEach(function(r){
      if (r.route && r.route.path){
        var method = '';

        for(method in r.route.methods){
          if(r.route.methods[method]){
            routes.push({method: method.toUpperCase(), path: parent + r.route.path});
          }
        }       

      } else if (r.handle && r.handle.name == 'router') {
        const routerName = r.regexp.source.replace("^\\","").replace("\\/?(?=\\/|$)","");
        return listRoutes(routes, r.handle.stack, parent + routerName);
      }
    });
    return routes;
  } else {
    return listRoutes([], app._router.stack);
  }
}

//Usage on app.js
const routes = listRoutes(); //array: ["method: path", "..."]

edit: code improvements

Image workaround with transparent pixels on the right to serve as right margin.

The image workaround for the same is to create a PNG or GIF image (image file formats that support transparency) which has a transparent portion on the right of the image exactly equal to the number of pixels that you want to give a right margin of (eg: 5px, 10px, etc.)

This works well consistently across fixed widths as well as widths in percentages. Practically a good solution for accordion headers having a plus/minus or up/down arrow image on the header's right!

Downside: Unfortunately, you cannot use JPG unless the background portion of the container and the background color of the CSS background image are of the same flat color (with out a gradient/vignette), mostly white/black etc.

Starting Python 3.8, the standard library comes with the quantiles function as part of the statistics module:

from statistics import quantiles

quantiles([1, 2, 3, 4, 5], n=100)
# [0.06, 0.12, 0.18, 0.24, 0.3, 0.36, 0.42, 0.48, 0.54, 0.6, 0.66, 0.72, 0.78, 0.84, 0.9, 0.96, 1.02, 1.08, 1.14, 1.2, 1.26, 1.32, 1.38, 1.44, 1.5, 1.56, 1.62, 1.68, 1.74, 1.8, 1.86, 1.92, 1.98, 2.04, 2.1, 2.16, 2.22, 2.28, 2.34, 2.4, 2.46, 2.52, 2.58, 2.64, 2.7, 2.76, 2.82, 2.88, 2.94, 3.0, 3.06, 3.12, 3.18, 3.24, 3.3, 3.36, 3.42, 3.48, 3.54, 3.6, 3.66, 3.72, 3.78, 3.84, 3.9, 3.96, 4.02, 4.08, 4.14, 4.2, 4.26, 4.32, 4.38, 4.44, 4.5, 4.56, 4.62, 4.68, 4.74, 4.8, 4.86, 4.92, 4.98, 5.04, 5.1, 5.16, 5.22, 5.28, 5.34, 5.4, 5.46, 5.52, 5.58, 5.64, 5.7, 5.76, 5.82, 5.88, 5.94]
quantiles([1, 2, 3, 4, 5], n=100)[49] # 50th percentile (e.g median)
# 3.0

quantiles returns for a given distribution dist a list of n - 1 cut points separating the n quantile intervals (division of dist into n continuous intervals with equal probability):

statistics.quantiles(dist, *, n=4, method='exclusive')

where n, in our case (percentiles) is 100.

You'd need to register DHTMLED.ocx

If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.

But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.

Or, if none of the above works then you can use following approach as it worked for me.

Imagine this is your button

<button class="btn" onclick="NavigateToPdf(${Id});"></button>

I got the value for ${Id} filled using jquery templates. You can use whatever suits your requirement. In the following function, I am setting window.location.href equal to controller name then action name and then finally parameter. I am able to successfully navigate.

function NavigateToPdf(id) {
    window.location.href = "Link/Pdf/" + id;
}

I hope it helps.

If data frame fits in a driver memory and you want to save to local files system you can convert Spark DataFrame to local Pandas DataFrame using toPandas method and then simply use to_csv:

df.toPandas().to_csv('mycsv.csv')

Otherwise you can use spark-csv:

• Spark 1.3

  df.save('mycsv.csv', 'com.databricks.spark.csv')
  

• Spark 1.4+

  df.write.format('com.databricks.spark.csv').save('mycsv.csv')
  

In Spark 2.0+ you can use csv data source directly:

df.write.csv('mycsv.csv')

The Regular Expression Way

If you need stricter replacement matching, PostgreSQL's regexp_replace function can match using POSIX regular expression patterns. It has the syntax regexp_replace(source, pattern, replacement [, flags ]).

I will use flags i and g for case-insensitive and global matching, respectively. I will also use \m and \M to match the beginning and the end of a word, respectively.

There are usually quite a few gotchas when performing regex replacment. Let's see how easy it is to replace a cat with a dog.

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog');
-->                    Cat bobdog cat cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'i');
-->                    dog bobcat cat cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'g');
-->                    Cat bobdog dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'gi');
-->                    dog bobdog dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat', 'dog', 'gi');
-->                    dog bobcat dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat\M', 'dog', 'gi');
-->                    dog bobdog dog cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat\M', 'dog', 'gi');
-->                    dog bobcat dog cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat(s?)\M', 'dog\1', 'gi');
-->                    dog bobcat dog dogs catfish

Even after all of that, there is at least one unresolved condition. For example, sentences that begin with "Cat" will be replaced with lower-case "dog" which break sentence capitalization.

Check out the current PostgreSQL pattern matching docs for all the details.

Update entire column with replacement text

Given my examples, maybe the safest option would be:

UPDATE table SET field = regexp_replace(field, '\mcat\M', 'dog', 'gi');

You can try this:

//Your class instance
Publication publication = new Publication();

//Get class with full path(with package name)
Class<?> c = Class.forName("com.example.publication.models.Publication");

//Get method
Method  method = c.getDeclaredMethod ("setTitle", String.class);

//set value
method.invoke (publication,  "Value to want to set here...");

I did another thing: delete a sheet only if it's exists - not to get an error if it doesn't:

Excel.DisplayAlerts = False 
Dim WS
For Each WS In Excel.Worksheets
    If WS.name = "Sheet2" Then
        Excel.sheets("Sheet2").Delete
        Exit For
    End If
Next
Excel.DisplayAlerts = True

Use the mod rewrite with R=301 - where you use a incremental version number:

To achieve > css/ver/file.css => css/file.css?v=ver

RewriteRule ^css/([0-9]+)/file.css$ css/file.css?v=$1 [R=301,L,QSA]

so example, css/10/file.css => css/file.css?v=10

Same can be applied to js/ files. Increment ver to force update, 301 forces re-cache

I have tested this across Chrome, Firefox, Opera etc

PS: the ?v=ver is just for readability, this does not cause the refresh

Lock is a questionable idea in JS which is intended to be threadless and not needing concurrency protection. You're looking to combine calls on deferred execution. The pattern I follow for this is the use of callbacks. Something like this:

var functionLock = false;
var functionCallbacks = [];
var lockingFunction = function (callback) {
    if (functionLock) {
        functionCallbacks.push(callback);
    } else {
        $.longRunning(function(response) {
             while(functionCallbacks.length){
                 var thisCallback = functionCallbacks.pop();
                 thisCallback(response);
             }
        });
    }
}

You can also implement this using DOM event listeners or a pubsub solution.

Have a look at the strcat function.

In particular, you could try this:

const char* name = "hello";
const char* extension = ".txt";

char* name_with_extension;
name_with_extension = malloc(strlen(name)+1+4); /* make space for the new string (should check the return value ...) */
strcpy(name_with_extension, name); /* copy name into the new var */
strcat(name_with_extension, extension); /* add the extension */

Adding to Gaby's post, my jdbc getTables() for Oracle 10g requires all caps to work:

"employee" -> "EMPLOYEE"

Otherwise I would get an exception:

java.sql.SqlExcepcion exhausted resultset

(even though "employee" is in the schema)

Control Panel >> Windows Firewall

Advanced settings >> Inbound Rules >> World Wide Web Services - Enable it All or (Domain, Private, Public) as needed.

You can try this. :) simple solution!

=IF(ISNUMBER(MATCH(I1,E:E,0)),"TRUE","")

I would recommend you having a look at the basics of conditioning in bash.

The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.

Usage:

elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)]

In short, edit your code segment to:

elif [ "$seconds" -gt 0 ]

You'd be fine with no compilation errors. Your final code segment should look like this:

#!/bin/sh    
if [ "$seconds" -eq 0 ];then
       $timezone_string="Z"
    elif [ "$seconds" -gt 0 ]
    then
       $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60`
    else
       echo "Unknown parameter"
    fi

Simple

var a=[{a:4}], b=[{b:5}]

angular.merge(a,b) // [{a:4, b:5}]

Tested on angular 1.4.1

For PowerShell users on Windows

The accepted answer did not work for me with npm 6.14. Neither adding no -- nor including it once does work. However, putting -- twice or putting "--" once before the arguments does the trick. Example:

npm run <my_script> -- -- <my arguments like --this>

Suspected reason

Like in bash, -- instructs PowerShell to treat all following arguments as literal strings, and not options (E.g see this answer). The issues seems to be that the command is interpreted one time more than expected, loosing the '--'. For instance, by doing

npm run <my_script> -- --option value

npm will run

<my_script> value

However, doing

npm run <my_script> "--" --option value

results in

<my_script> "--option" "value"

which works fine.

I found a shorter and very straightforward solution which works seamlessly, and with authentication as well, using express-http-proxy:

const url = require('url');
const proxy = require('express-http-proxy');

// New hostname+path as specified by question:
const apiProxy = proxy('other_domain.com:3000/BLABLA', {
    proxyReqPathResolver: req => url.parse(req.baseUrl).path
});

And then simply:

app.use('/api/*', apiProxy);

Note: as mentioned by @MaxPRafferty, use req.originalUrl in place of baseUrl to preserve the querystring:

    forwardPath: req => url.parse(req.baseUrl).path

Update: As mentioned by Andrew (thank you!), there's a ready-made solution using the same principle:

npm i --save http-proxy-middleware

And then:

const proxy = require('http-proxy-middleware')
var apiProxy = proxy('/api', {target: 'http://www.example.org/api'});
app.use(apiProxy)

Documentation: http-proxy-middleware on Github

I know I'm late to join this party, but I hope this helps someone.

I had the same problem, some of the users have answered this. Before push you must have your first commit. Now for new users I've created a series of simple steps. Before that you need to install git and run in command line:

• git config user.email "your email"
• git config user.name "name"

The steps for creating a remote repository (I use dropbox as remote repository):

1. create a directory in Dropbox (or on your remote server)
2. go to the Dropbox dir (remote server dir)
3. type git command: git init --bare
4. on your local drive create your local directory
5. go to local directory
6. type git command: git init
7. add initial files, by typing git command:: git add <filename> 
8. type git command: git commit -a -m "initial version" (if you don't commit you can't do the initial push
9. type git command: git remote add name <path to Dropbox/remote server> 
10. git push name brach (for first commit the branch should be master)

I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter

What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.

If so, you can look under Run > Edit Configurations

Consider:

class Bike(object):
    def __init__(self, name, weight, cost):
        self.name = name
        self.weight = weight
        self.cost = cost

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),      # <--
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165),    # <--
    }

# Markup of 20% on all sales
margin = .2
# Revenue minus cost after sale
for bike in bikes.values():
    profit = bike.cost * margin
    print(profit)

Output:

33.0
20.0

The difference is that in your bikes dictionary, you're initializing the values as lists [...]. Instead, it looks like the rest of your code wants Bike instances. So create Bike instances: Bike(...).

As for your error

AttributeError: 'list' object has no attribute 'cost'

this will occur when you try to call .cost on a list object. Pretty straightforward, but we can figure out what happened by looking at where you call .cost -- in this line:

profit = bike.cost * margin

This indicates that at least one bike (that is, a member of bikes.values() is a list). If you look at where you defined bikes you can see that the values were, in fact, lists. So this error makes sense.

But since your class has a cost attribute, it looked like you were trying to use Bike instances as values, so I made that little change:

[...] -> Bike(...)

and you're all set.

Perhaps it's changed now, but I have used a separate stylesheet with this element:

.feedEkList iframe
{
max-width: 435px!important;
width: 435px!important;
height: 320px!important;
}

to successfully style embedded youtube iframes...see the blog posts on this page.

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

Sunderls lead me to the answer. Except filter: scale does not exist, but filter: blur does.

Apply the next declarations to the elements that appear blurred (in my case they were inside a transformed element):

backface-visibility: hidden;    
-webkit-filter: blur(0);

It almost worked perfectly. "Almost" because i'm using a transition and while in transition, elements don't look perfect, but once the transition is done, they do.

As of the comment: You should be able to use Apache Commons ReverseListIterator

Iterable<String> reverse 
    = new IteratorIterable(new ReverseListIterator(stringList));

for(String string: reverse ){
    //...do something
}

As @rogerdpack said, you need to wrap the ReverseListIterator as an Iterable.

For those using the context menu api, the docs are not immediately clear on how to obtain tab information.

  chrome.contextMenus.onClicked.addListener(function(info, tab) {
    console.log(info);
    return console.log(tab);
  });

I had the same problem... a JDK and plug-in version conflict.

I compiled using 1.8 ... the latest one, and that message started to appear. So I've searched for the JRE 7 (http://www.oracle.com/technetwork/java/javase/downloads/server-jre7-downloads-1931105.html)... and installed it... again... Now 1.8 and 1.7 in the same computer.

Using NetBeans, and compiling, and targeting to version 1.7, fixed my problem.

In general, i agree with above answers that recommend to add maven dependency, but i prefer following solution.

Add a dependency with API classes for full JavaEE profile:

<properties>
    <javaee-api.version>7.0</javaee-api.version>
    <hibernate-entitymanager.version>5.1.3.Final</hibernate-entitymanager.version>
</properties>

<depencies>
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>${javaee-api.version}</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

Also add dependency with particular JPA provider like antonycc suggested:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>${hibernate-entitymanager.version}</version>
</dependency>

Note <scope>provided</scope> in API dependency section: this means that corresponding jar will not be exported into artifact's lib/, but will be provided by application server. Make sure your application server implements specified version of JavaEE API.

Assuming your WebSocket server is listening on the same port as from which the page is being requested, I would suggest:

function createWebSocket(path) {
    var protocolPrefix = (window.location.protocol === 'https:') ? 'wss:' : 'ws:';
    return new WebSocket(protocolPrefix + '//' + location.host + path);
}

Then, for your case, call it as follows:

var socket = createWebSocket(location.pathname + '/to/ws');

.SILENT:

Type " .SILENT: " in the beginning of your script without colons.

for classes you can use:

div[class^="jander"]

Similar to @craig, I recently built a shortcut library.

https://github.com/blainekasten/shortcut.js

Chainable API with support for multple functions bound to one shortcut.

This code snippet worked for me. I have an issue with the parsing batch of XML files. I had to encode them to 'iso-8859-5'

import xml.etree.ElementTree as ET

tree = ET.parse(filename, parser = ET.XMLParser(encoding = 'iso-8859-5'))

With Support Library 26.0 (and Android O) fonts can be loaded from resource easily with:

Typeface typeface = ResourcesCompat.getFont(Context context, int fontResourceId) 

Docs for the method.

More info can be found here.

For those who intend to use venv:

If you don't already have pip for Python 3:

sudo apt install python3-pip

Install venv package:

sudo apt install python3.7-venv

Create virtual environment (which will be bootstrapped with pip by default):

python3.7 -m venv /path/to/new/virtual/environment

To activate the virtual environment, source the appropriate script for the current shell, from the bin directory of the virtual environment. The appropriate scripts for the different shells are:

bash/zsh – activate

fish – activate.fish

csh/tcsh – activate.csh

For example, if using bash:

source /path/to/new/virtual/environment/bin/activate

Optionally, to update pip for the virtual environment (while it is activated):

pip install --upgrade pip

When you want to deactivate the virtual environment:

deactivate 

See the MSDN getch docs. Specifically:

The _getch and_getwch functions read a single character from the console without echoing the character. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

The Python function returns a character. you can use ord() to get an integer value you can test, for example keycode = ord(msvcrt.getch()).

So if you read an 0x00 or 0xE0, read it a second time to get the key code for an arrow or function key. From experimentation, 0x00 precedes F1-F10 (0x3B-0x44) and 0xE0 precedes arrow keys and Ins/Del/Home/End/PageUp/PageDown.

For offline Javadoc from zip file rather than extracting it.

Why this approach?

This is already answered which uses extracted zip data but it consumes more memory than simple zip file.

Comparison of zip file and extracted data.

jdk-6u25-fcs-bin-b04-apidocs.zip  --->  ~57 MB
after extracting this zip file  --->  ~264 MB !

So this approach saves my approx. 200 MB.

How to use apidocs.zip?

1.Open Windows -> Preferences

2.Select jre from Installed JREs then Click Edit...

3.Select all .jar files from JRE system libraries then Click Javadoc Location...

4.Browse for apidocs.zip file for Archive path and set Path within archive as shown above. That's it.

5.Put cursor on any class name or method name and hit Shift + F2

I know the OP is asking for a mysql answer but since I found the other answers not working for me,

• Most of them fail with order by
• Or they are simply very inefficient and make your query very slow for a fat table

So to save time for others like me, just index the row after retrieving them from database

example in PHP:

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1;
}

example in PHP using offset and limit for paging:

$limit = 20; //page size
$offset = 3; //page number

$users = UserRepository::loadAllUsersAndSortByScore();

foreach($users as $index=>&$user){
    $user['rank'] = $index+1+($limit*($offset-1));
}

Sounds like you're working in just one table so something like this:

update your_table
set B = A
where B is null

var arrayOne = [1,2,3]
var arrayTwo = [4,5,6]

if you want result as : [1,2,3,[4,5,6]]

arrayOne.append(arrayTwo)

above code will convert arrayOne as a single element and add it to the end of arrayTwo.

if you want result as : [1, 2, 3, 4, 5, 6] then,

arrayOne.append(contentsOf: arrayTwo)

above code will add all the elements of arrayOne at the end of arrayTwo.

Thanks.

Use String split method to remove :00.000

var formatedTime = currentTime.toString().split(':')
Text(formatedTime[0])

======= OR USE BELOW code for YYYY-MM-DD HH:MM:SS format without using library ====

var stringList =  DateTime.now().toIso8601String().split(new RegExp(r"[T\.]"));
var formatedDate = "${stringList[0]} ${stringList[1]}";

You have to read the data too.

Check out : http://www.doughellmann.com/PyMOTW/urllib2/ to understand it.

response = urllib2.urlopen(..)
headers = response.info()
data = response.read()

Of course, what you want is to render it in browser and aaronasterling's answer is what you want.

• Add your script to /etc/init.d/ directory
• Update your rc run-levels: $ update-rc.d myScript.sh defaults NN where NN is the order in which it should be executed. 99 for example will mean it would be run after 98 and before 100.
