Assuming we imported pandas as pd and df is our dataframe

pd.to_datetime(df['date'], unit='s')

works for me.

You wont be able to get python to tell you where the JSON is incorrect. You will need to use a linter online somewhere like this

This will show you error in the JSON you are trying to decode.

Even ng update --all --force doesn't work?

It might be simply when you're performing Angular upgrade from version when .angular-cli.json (for example Angular 4) has been used to one of the newer versions having angular.json. In that case you might need to delete the .angular-cli.json and replace with equivalent metadata angular.json. After that, you'll be able to perform update from one command or step-by-step.

To translate your *nix style command script to windows/command batch style it would go like this:

SET PROJ_HOME=%USERPROFILE%/proj/111
SET PROJECT_BASEDIR=%PROJ_HOME%/exercises/ex1
mkdir "%PROJ_HOME%"

mkdir on windows doens't have a -p parameter : from the MKDIR /? help:

MKDIR creates any intermediate directories in the path, if needed.

which basically is what mkdir -p (or --parents for purists) on *nix does, as taken from the man guide

you can also add inline css for adding image as a background as per below example

<div class="item active" style="background-image: url(../../foo.png);">

The omp_get_num_threads() function returns the number of threads that are currently in the team executing the parallel region from which it is called. You are calling it outside of the parallel region, which is why it returns 1.

There are few typical methods how we control components render in React.

But, I haven't used any of these in here, I just used the ref's to namespace underlying children to the component.

JConsole is an easy way to monitor a running Java application or you can use a Profiler to get more detailed information on your application. I like using the NetBeans Profiler for this.

The simplest solution is to define the row limit and execute. This is done for safety purposes.

format : "DD/MM/YYYY" should resolve your issue. If you need more help regarding available formats, please visit http://momentjs.com/ which is used by this control internally.

I was facing an issue where this "format" thing was working fine on local machine but when I deployed the application on server, the date was not getting populated and the control was empty. when I commented the format code, it started working but then I didn't have the format that I needed. I fixed that issue using globalization entries in web.config.

<system.web>
    <globalization
    requestEncoding="utf-8"
    responseEncoding="utf-8"
    culture="en-GB"
    uiCulture="en-GB" />    
</system.web>

This helped in ensuring that both local & server environments have same culture.

The above answers are all fine, but the essence of the issue is that some headers are set one way, and others are set other ways. See above for 'restricted header' lists. FOr these, you just set them as a property. For others, you actually add the header. See here.

    request.ContentType = "application/x-www-form-urlencoded";

    request.Accept = "application/json";

    request.Headers.Add(HttpRequestHeader.Authorization, "Basic " + info.clientId + ":" + info.clientSecret);

In my case for a wcf rest services project I had to add a runtime section to the web.config where there the requested dll was:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="DotNetOpenAuth.Core" publicKeyToken="2780ccd10d57b246" />
        <bindingRedirect oldVersion="0.0.0.0-4.1.0.0" newVersion="4.1.0.0" />
      </dependentAssembly>
.
.
.
  <runtime>

I found a website with a "simple" tutorial: http://www.winprog.org/tutorial/start.html

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

All the above answers details about Single main threaded Request Handler.

setting:

 server.setExecutor(java.util.concurrent.Executors.newCachedThreadPool());

Allows multiple request serving via multiple threads using executor service.

So the end code will be something like below:

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
public class App {
    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/test", new MyHandler());
        //Thread control is given to executor service.
        server.setExecutor(java.util.concurrent.Executors.newCachedThreadPool());
        server.start();
    }
    static class MyHandler implements HttpHandler {
        @Override
        public void handle(HttpExchange t) throws IOException {
            String response = "This is the response";
            long threadId = Thread.currentThread().getId();
            System.out.println("I am thread " + threadId );
            response = response + "Thread Id = "+threadId;
            t.sendResponseHeaders(200, response.length());
            OutputStream os = t.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }
    }
}

This works for me

I have tested it, and it worked.

NATIVE is Non access modifier.it can be applied only to METHOD. It indicates the PLATFORM-DEPENDENT implementation of method or code.

No, there isn't a syntax for extracting text using regular expressions. You have to use the ordinary string manipulation functions.

Alternatively select the entire value from the database (or the first n characters if you are worried about too much data transfer) and then use a regular expression on the client.

Yes, this is probably a bit late. But one thing to add to everyone else's comments is that, Camel is actually a toolbox rather than a complete set of features. You should bear this in mind when developing and need to do various transformations and protocol conversions.

Camel itself relies on other frameworks and therefore sometimes you need to understand those as well in order to understand which is best suited for your needs. There are for example multiple ways to handle REST. This can get a bit confusing at first, but once you starting using and testing you will feel at ease and your knowledge of the different concepts will increase.

If you are not using annotation based Servlet then please remove annotation @WebServlet("/YourServletName") from the starting of the servlet. This annotation confuses the mapping with web.xml, after removing this annotation Tomcat server will work properly.

public enum Environment
{
    PROD("https://prod.domain.com:1088/"),
    SIT("https://sit.domain.com:2019/"),
    CIT("https://cit.domain.com:8080/"),
    DEV("https://dev.domain.com:21323/");

    private String url;

    Environment(String envUrl) {
        this.url = envUrl;
    }

    public String getUrl() {
        return url;
    }
}

String prodUrl = Environment.PROD.getUrl();

It will print:

https://prod.domain.com:1088/

This design for enum string constants works in most of the cases.

Try surrounding the path in quotes. i.e "C:\Program Files\Appname\config.file"

image_tag("/icons/icon.gif", height: '32', width: '32') I need to set height: '50px', width: '50px' to image tag and this code works from first try note I tried all the above code but no luck so this one works and here is my code from my _nav.html.erb:
<%= image_tag("#{current_user.image}", height: '50px', width: '50px') %>

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

I've been using path.js for my client side routing. I've found it to be quite succinct and lightweight (it's also been published to NPM too), and makes use of hash based navigation.

A POST request can include a query string, however normally it doesn't - a standard HTML form with a POST action will not normally include a query string for example.

Link to Working Examples

Solution 0

This can be accompished using pivot tables.

Solution 1

Use the unique formula to get all the distinct values. Then use countif to get the count of each value. See the working example link at the top to see exactly how this is implemented.

Unique Values        Count
=UNIQUE(A3:A8)       =COUNTIF(A3:A8;B3)
                     =COUNTIF(A3:A8;B4)
                     ...

Solution 2

If you setup your data as such:

City    
----    
London   1
Paris    1
London   1
Berlin   1
Rome     1
Paris    1

Then the following will produce the desired result.

=sort(transpose(query(A3:B8,"Select sum(B) pivot (A)")),2,FALSE)

I'm sure there is a way to get rid of the second column since all values will be 1. Not an ideal solution in my opinion.

Regex to the rescue!

'h*ell*o*w*orld'

function clean($data){
    $data = rawurldecode($data);

You can use the sp_help 'TableName'

I had the same error, but don't know why it appeared. After searching solution I migrated project to AndroidX (Refactor -> Migrate to AndroidX...) and then manually changed whole classes imports etc. and in layout files too (RecyclerViews, ConstraintLayouts, Toolbars etc.). I changed also compileSdkVersion and targetSdkVersion to 28 version and whole project/application works fine.

Use REQUEST. Nobody cares about the speed of such a simple operation, and it's much cleaner code.

ALTER TABLE [TableName] ADD CONSTRAINT  [constraintName] UNIQUE ([columns])

I faced this problem when I tried to pass a serializable model object. Inside that model, another model was a variable but that wasn't serializable. That's why I face this problem. Make sure all the model inside of an model is serializable.

You need a Flask view that will receive POST data and an HTML form that will send it.

from flask import request

@app.route('/addRegion', methods=['POST'])
def addRegion():
    ...
    return (request.form['projectFilePath'])

<form action="{{ url_for('addRegion') }}" method="post">
    Project file path: <input type="text" name="projectFilePath"><br>
    <input type="submit" value="Submit">
</form>

I think your second option is the best bet. Generally in floating-point comparison you often only care that one value is within a certain tolerance of another value, controlled by the selection of epsilon.

listOLists = [[1,2,3],[4,5,6],[7,8,9,10]]
for list in itertools.product(*listOLists):
  print list;

I hope you find that as elegant as I did when I first encountered it.

You need to define a new type and define your function to return that type.

CREATE TYPE my_type AS (f1 varchar(10), f2 varchar(10) /* , ... */ );

CREATE OR REPLACE FUNCTION get_object_fields(name text) 
RETURNS my_type 
AS 
$$

DECLARE
  result_record my_type;

BEGIN
  SELECT f1, f2, f3
  INTO result_record.f1, result_record.f2, result_record.f3
  FROM table1
  WHERE pk_col = 42;

  SELECT f3 
  INTO result_record.f3
  FROM table2
  WHERE pk_col = 24;

  RETURN result_record;

END
$$ LANGUAGE plpgsql; 

If you want to return more than one record you need to define the function as returns setof my_type

Update

Another option is to use RETURNS TABLE() instead of creating a TYPE which was introduced in Postgres 8.4

CREATE OR REPLACE FUNCTION get_object_fields(name text) 
  RETURNS TABLE (f1 varchar(10), f2 varchar(10) /* , ... */ )
...

Create a Batch file (.bat) in Windows with the following command in it:

I would suggest looking at the javadoc for Thread class.

You have multiple mechanisms for thread manipulation.

• Your main thread could join() the three threads serially, and would then not proceed until all three are done.

• Poll the thread state of the spawned threads at intervals.

• Put all of the spawned threads into a separate ThreadGroup and poll the activeCount() on the ThreadGroup and wait for it to get to 0.

• Setup a custom callback or listener type of interface for inter-thread communication.

I'm sure there are plenty of other ways I'm still missing.

They are the same concepts, apart from the NULL value returned.

See below:

declare @table1 table( col1 int, col2 int );
insert into @table1 select 1, 11 union all select 2, 22;

declare @table2 table ( col1 int, col2 int );
insert into @table2 select 10, 101 union all select 2, 202;

select
    t1.*,
    t2.*
from @table1 t1
full outer join @table2 t2 on t1.col1 = t2.col1
order by t1.col1, t2.col1;

/* full outer join
col1        col2        col1        col2
----------- ----------- ----------- -----------
NULL        NULL        10          101

2           22          2           202
*/

select
    t1.*,
    t2.*
from @table1 t1
cross join @table2 t2
order by t1.col1, t2.col1;

/* cross join
col1        col2        col1        col2
----------- ----------- ----------- -----------
1           11          2           202
1           11          10          101
2           22          2           202

You could implement a onActivityResult in Class B as well and launch Class C using startActivityForResult. Once you get the result in Class B then set the result there (for Class A) based on the result from Class C. I haven't tried this out but I think this should work.

Another thing to look out for is that Activity A should not be a singleInstance activity. For startActivityForResult to work your Class B needs to be a sub activity to Activity A and that is not possible in a single instance activity, the new Activity (Class B) starts in a new task.

Example:

You have to use the TO_NUMBER function:

select * from exception where exception_value = to_number('105')

This is a twist on 'exans' answer that uses Named Aggregations. It's the same but with argument unpacking which allows you to still pass in a dictionary to the agg function.

The named aggs are a nice feature, but at first glance might seem hard to write programmatically since they use keywords, but it's actually simple with argument/keyword unpacking.

animals = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                         'height': [9.1, 6.0, 9.5, 34.0],
                         'weight': [7.9, 7.5, 9.9, 198.0]})
 
agg_dict = {
    "min_height": pd.NamedAgg(column='height', aggfunc='min'),
    "max_height": pd.NamedAgg(column='height', aggfunc='max'),
    "average_weight": pd.NamedAgg(column='weight', aggfunc=np.mean)
}

animals.groupby("kind").agg(**agg_dict)

The Result

      min_height  max_height  average_weight
kind                                        
cat          9.1         9.5            8.90
dog          6.0        34.0          102.75

PERIOD_DIFF calculates months between two dates.

For example, to calculate the difference between now() and a time column in your_table:

select period_diff(date_format(now(), '%Y%m'), date_format(time, '%Y%m')) as months from your_table;

Snagged from Oracle OTN forums

Use alter table to add column, for example:

alter table tableName add(columnName NUMBER);

Then create a sequence:

CREATE SEQUENCE SEQ_ID
START WITH 1
INCREMENT BY 1
MAXVALUE 99999999
MINVALUE 1
NOCYCLE;

and, the use update to insert values in column like this

UPDATE tableName SET columnName = seq_test_id.NEXTVAL

This is how it worked for me:

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("DELETE");
int responseCode = connection.getResponseCode();

I'll go into differences at the hardware level, on x86. This is mostly irrelevant unless you're writing a compiler or using assembly language. But it's nice to know.

Firstly, x86 has native support for the two's complement representation of signed numbers. You can use other representations but this would require more instructions and generally be a waste of processor time.

What do I mean by "native support"? Basically I mean that there are a set of instructions you use for unsigned numbers and another set that you use for signed numbers. Unsigned numbers can sit in the same registers as signed numbers, and indeed you can mix signed and unsigned instructions without worrying the processor. It's up to the compiler (or assembly programmer) to keep track of whether a number is signed or not, and use the appropriate instructions.

Firstly, two's complement numbers have the property that addition and subtraction is just the same as for unsigned numbers. It makes no difference whether the numbers are positive or negative. (So you just go ahead and ADD and SUB your numbers without a worry.)

The differences start to show when it comes to comparisons. x86 has a simple way of differentiating them: above/below indicates an unsigned comparison and greater/less than indicates a signed comparison. (E.g. JAE means "Jump if above or equal" and is unsigned.)

There are also two sets of multiplication and division instructions to deal with signed and unsigned integers.

Lastly: if you want to check for, say, overflow, you would do it differently for signed and for unsigned numbers.

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

Just a note...

If you add that code to setclasspath.bat or setclasspath.sh, it will actually be used by all of Tomcat's scripts you could run, rather than just Catalina.

The method for setting the variable is as the other's have described.

You can do this without using refs. This approach is preferred, since refs can lead to fragile code. The React docs advise finding other solutions where possible:

If you have not programmed several apps with React, your first inclination is usually going to be to try to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. Placing the state there often eliminates any desire to use refs to "make things happen" – instead, the data flow will usually accomplish your goal.

Instead, we'll use a state variable to focus the second input field.

1. Add a state variable that we'll pass as a prop to the DescriptionInput:

   initialState() {
     return {
       focusDescriptionInput: false,
     };
   }
   

2. Define a handler method that will set this state variable to true:

   handleTitleInputSubmit() {
     this.setState(focusDescriptionInput: true);
   }
   

3. Upon submitting / hitting enter / next on the TitleInput, we'll call handleTitleInputSubmit. This will set focusDescriptionInput to true.

   <TextInput 
      style = {styles.titleInput}
      returnKeyType = {"next"}
      autoFocus = {true}
      placeholder = "Title" 
      onSubmitEditing={this.handleTitleInputSubmit}
   />
   

4. DescriptionInput's focus prop is set to our focusDescriptionInput state variable. So, when focusDescriptionInput changes (in step 3), DescriptionInput will re-render with focus={true}.

   <TextInput
      style = {styles.descriptionInput}          
      multiline = {true}
      maxLength = {200}
      placeholder = "Description" 
      focus={this.state.focusDescriptionInput}
   />
   

This is a nice way to avoid using refs, since refs can lead to more fragile code :)

EDIT: h/t to @LaneRettig for pointing out that you'll need to wrap the React Native TextInput with some added props & methods to get it to respond to focus:

    // Props:
    static propTypes = { 
        focus: PropTypes.bool,
    } 

    static defaultProps = { 
        focus: false,
    } 

    // Methods:
    focus() {
        this._component.focus(); 
    } 

    componentWillReceiveProps(nextProps) {
        const {focus} = nextProps; 

        focus && this.focus(); 
    }

Use a Scanner and pass in the delimiter and the original string:

result = new Scanner(result).useDelimiter("\n").next();

How about...

console = { log : function(text) { alert(text); } }

In my case setting typescript.disableAutomaticTypeAcquisition in Visual Studio Code to true seemed to help.

storage_path()

The storage_path function returns the fully qualified path to the storage directory:

$path = storage_path();

You may also use the storage_path function to generate a fully qualified path to a given file relative to the storage directory:

$app_path = storage_path('app');
$file_path = storage_path('app/file.txt');

If you are changing the font size, but it is only working for the currently open file, then I suspect that you are changing the wrong preferences.

• On the Eclipse toolbar, select Window ? Preferences
• Set the font size, General ? Appearance ? Colors and Fonts ? Java ? Java Editor Text Font).
• Save the preferences.

Check that you do not have per-project preferences. These will override the top-level preferences.

Eclipse v4.2 (Juno) note

Per comment below, this has moved to the Eclipse Preferences menu (no longer named the Window menu).

Eclipse v4.3 (Kepler) note

The Window menu is live again, that is, menu Window ? Preferences.

Note Be sure to check out the ChandraBhan Singh's answer, it shows the key bindings to change the font size.

First you have to ensure that there is a SMTP server listening on port 25.

To look whether you have the service, you can try using TELNET client, such as:

C:\> telnet localhost 25

(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.

$ telnet localhost 25

If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.

If you don't have the service, you can use these:

• A mock SMTP server that will mimic the behavior of actual SMTP server, as you are using Java, it is natural to suggest Dumbster fake SMTP server. This even can be made to work within JUnit tests (with setup/tear down/validation), or independently run as separate process for integration test.
• If your host is Windows, you can try installing Mercury email server (also comes with WAMPP package from Apache Friends) on your local before running above code.
• If your host is Linux or UNIX, try to enable the mail service such as Postfix,
• Another full blown SMTP server in Java, such as Apache James mail server.

If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.

Apply float:left; to both of your divs should make them stand side by side.

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

A stack has a limited capacity, while a heap is not. The typical stack for a process or thread is around 8K. You cannot change the size once it's allocated.

A stack variable follows the scoping rules, while a heap one doesn't. If your instruction pointer goes beyond a function, all the new variables associated with the function go away.

Most important of all, you can't predict the overall function call chain in advance. So a mere 200 bytes allocation on your part may raise a stack overflow. This is especially important if you're writing a library, not an application.

Depending if you have Underscore or Babel here is a Benchmark of the different way of deep cloning an array.

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

I think you must also remove security auto config from your @SpringBootApplication annotated class:

@EnableAutoConfiguration(exclude = {
    org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
    org.springframework.boot.actuate.autoconfigure.ManagementSecurityAutoConfiguration.class})

I have read several articles discouraging inheritance in projects (as opposed to libraries/frameworks), and encouraging to program agaisnt interfaces, no against implementations.
They also advocate OO by composition: if you need the functions in class a and b, make c having members/fields of this type:

class C
{
    private $a, $b;

    public function __construct($x, $y)
    {
        $this->a = new A(42, $x);
        $this->b = new B($y);
    }

    protected function DoSomething()
    {
        $this->a->Act();
        $this->b->Do();
    }
}

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('my_static_block_name')->toHtml() ?>

There is another difference to keep in mind between the two. With CSS, the :hover state is always deactivated when the mouse moves off an element. However, with JavaScript, the onmouseout event is not fired when the mouse moves off the element onto browser chrome rather than onto the rest of the page.

This happens more often than you might think, especially when you're making a navbar at the top of your page with custom hover states.

It is not htop-like, but you could use atop. However, to display disk activity per process, it needs a kernel patch (available from the site). These kernel patches are now obsoleted, only to show per-process network activity an optional module is provided.

I can confirm that the solution by delphifirst works and is the easiest, simplest solution to the problem of running a python script with elevated privileges.

I created a shortcut to the python executable (python.exe) and then modified the shortcut by adding my script's name after the call to python.exe. Next I checked "run as administrator" on the "compatibility tab" of the shortcut. When the shortcut is executed, you get a prompt asking permission to run the script as an administrator.

My particular python application was an installer program. The program allows installing and uninstalling another python app. In my case I created two shortcuts, one named "appname install" and the other named "appname uninstall". The only difference between the two shortcuts is the argument following the python script name. In the installer version the argument is "install". In the uninstall version the argument is "uninstall". Code in the installer script evaluates the argument supplied and calls the appropriate function (install or uninstall) as needed.

I hope my explanation helps others more quickly figure out how to run a python script with elevated privileges.

When you get a UnicodeEncodeError, it means that somewhere in your code you convert directly a byte string to a unicode one. By default in Python 2 it uses ascii encoding, and utf8 encoding in Python3 (both may fail because not every byte is valid in either encoding)

To avoid that, you must use explicit decoding.

If you may have 2 different encoding in your input file, one of them accepts any byte (say UTF8 and Latin1), you can try to first convert a string with first and use the second one if a UnicodeDecodeError occurs.

def robust_decode(bs):
    '''Takes a byte string as param and convert it into a unicode one.
First tries UTF8, and fallback to Latin1 if it fails'''
    cr = None
    try:
        cr = bs.decode('utf8')
    except UnicodeDecodeError:
        cr = bs.decode('latin1')
    return cr

If you do not know original encoding and do not care for non ascii character, you can set the optional errors parameter of the decode method to replace. Any offending byte will be replaced (from the standard library documentation):

Replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on decoding and ‘?’ on encoding.

bs.decode(errors='replace')

select COUNT(*)
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id

you are looking for PHP’s empty() function

You can use display: table-cell in order to render the div as a table cell and then use vertical-align like you would do in a normal table cell.

#AlertDiv {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

You can try it here: http://jsfiddle.net/KaXY5/424/

Use 3 curly braces if you want to echo

{{{ $usersType or '' }}}

This line of JS code takes the link without params (ie before '?') and then append params to it.

window.location.href = (window.location.href.split('?')[0]) + "?p1=ABC&p2=XYZ";

The above line of code is appending two params p1 and p2 with respective values 'ABC' and 'XYZ' (for better understanding).

Just a small correction to the first answer in this thread.

Even for Stack, you need to create new object with generics if you are using Stack from java util packages.

Right usage:
    Stack<Integer> s = new Stack<Integer>();
    Stack<String> s1 = new Stack<String>();

    s.push(7);
    s.push(50);

    s1.push("string");
    s1.push("stack");

if used otherwise, as mentioned in above post, which is:

    /*
    Stack myStack = new Stack();
    // add any type of elements (String, int, etc..)
    myStack.push("Hello");
    myStack.push(1);
    */

Although this code works fine, has unsafe or unchecked operations which results in error.

Dollar sign is used in ecmascript 2015-2016 as 'template literals'. Example:

var a = 5;
var b = 10;
console.log(`Sum is equal: ${a + b}`); // 'Sum is equlat: 15'

Here working example: https://es6console.com/j3lg8xeo/ Notice this sign " ` ",its not normal quotes.

U can also meet $ while working with library jQuery.

$ sign in Regular Expressions means end of line.

I was having some trouble with this, and the "X:not():not()" method wasn't working for me.

I ended up resorting to this strategy:

INPUT {
    /* styles */
}
INPUT[type="radio"], INPUT[type="checkbox"] {
    /* styles that reset previous styles */
}

It's not nearly as fun, but it worked for me when :not() was being pugnacious. It's not ideal, but it's solid.

With Selenium Webdriver would be something like this:

assertTrue(!isElementPresent(By.linkText("Empresas en Misión")));

With eager evaluation, variables essentially turn into their values any time you look at them (to paraphrase). That said, Python does have built-in namespaces. For example, locals() will return a dictionary mapping a function's variables' names to their values, and globals() does the same for a module. Thus:

for name, value in globals().items():
    if value is unknown_variable:
        ... do something with name

Note that you don't need to import anything to be able to access locals() and globals().

Also, if there are multiple aliases for a value, iterating through a namespace only finds the first one.

One easy solution is to use HTML entities instead of actual characters. For example, the "[email protected]" will be converted into :

<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#109;&#101;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;">email me</A>

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

Whenever I have a class that contains a nested class that is of any significant size/complexity, I mark the class as partial and put the nested class in a separate file. I name the file containing the nested class using the rule: [class name].[nested class name].cs.

The following MSDN blog explains using partial classes with nested classes for maintainability: http://blogs.msdn.com/b/marcelolr/archive/2009/04/13/using-partial-classes-with-nested-classes-for-maintainability.aspx

If you get the server response as a String, without using a third party library you can do

JSONObject json = new JSONObject(response);
JSONObject jsonResponse = json.getJSONObject("response");
String team = jsonResponse.getString("Team");

Here is the documentation

Otherwise to parse json you can use Gson or Jackson

EDIT without libraries (not tested)

Why setContentView() in Android Had Been So Popular Till Now?

setContentView(int layoutid) - method of activity class. It shows layout on screen.

R.layout.main - is an integer number implemented in nested layout class of R.java class file.

At the run time device will pick up their layout based on the id given in setcontentview() method.

http://www.kernel.org/pub/software/scm/git/docs/git-revert.html

using git revert <commit> will create a new commit that reverts the one you dont want to have.

You can specify a list of commits to revert.

An alternative: http://git-scm.com/docs/git-reset

git reset will reset your copy to the commit you want.

function closeWin()   // Tested Code
{
var someIframe = window.parent.document.getElementById('iframe_callback');
someIframe.parentNode.removeChild(window.parent.document.getElementById('iframe_callback'));
}


<input class="question" name="Close" type="button" value="Close" onClick="closeWin()" tabindex="10" /> 

You may have imported,

project/controllers/base

inside the

project/controllers/routes

You have already imported before. That's not supported.

Set a tempHeight as a static variable(initially 0).

static void findHeight(Node node, int count) {

    if (node == null) {
        return;
    }
    if ((node.right == null) && (node.left == null)) {
        if (tempHeight < count) {
            tempHeight = count;

        }

    }

    findHeight(node.left, ++count);
    count--; //reduce the height while traversing to a different branch
    findHeight(node.right, ++count);

}

If you just want to load image (Asynchronously!) - just add this small extension to your swift code:

extension UIImageView {
    public func imageFromUrl(urlString: String) {
        if let url = NSURL(string: urlString) {
            let request = NSURLRequest(URL: url)
            NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {
                (response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in
                if let imageData = data as NSData? {
                    self.image = UIImage(data: imageData)
                }
            }
        }
    }
}

And use it this way:

myImageView.imageFromUrl("https://robohash.org/123.png")

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

I solved this by setting the HR background-color to black like so:

<hr style="width: 100%; color: black; height: 1px; background-color:black;" />

<form onsubmit="return false;">
   ...
</form>

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

System.Data.SQLite has a dependency on System.Data.SQLite.interop make sure both packages are the same version and are both x86.

This is an old question, but I tried all the above. I was working on a strictly x86 project, so there was not two folders /x86, /x64. But for some reason, the System.Data.SQLite was a different version to System.Data.SQLite.interop, once I pulled down matching dlls the problem was fixed.

on OSX assure you have launched the Docker application before issuing

docker ps

or docker build ... etc ... yes it seems strange and somewhat misleading that issuing

docker --version

gives version even though the docker daemon is not running ... ditto for those other version cmds ... I just encountered exactly the same symptoms ... this behavior on OSX is different from on linux

As mentioned in the React documentation, there is no guarantee of setState being fired synchronously, so your console.log may return the state prior to it updating.

Michael Parker mentions passing a callback within the setState. Another way to handle the logic after state change is via the componentDidUpdate lifecycle method, which is the method recommended in React docs.

Generally we recommend using componentDidUpdate() for such logic instead.

This is particularly useful when there may be successive setStates fired, and you would like to fire the same function after every state change. Rather than adding a callback to each setState, you could place the function inside of the componentDidUpdate, with specific logic inside if necessary.

// example
componentDidUpdate(prevProps, prevState) {
  if (this.state.value > prevState.value) {
    this.foo();  
  }
}

if( strtotime($database_date) > strtotime('now') ) {

xcopy "%userprofile%\Desktop\?????????" "D:\Backup\" /s/h/e/k/f/c

should work, assuming that your language setting allows Cyrillic (or you use Unicode fonts in the console).

For reference about the arguments: http://ss64.com/nt/xcopy.html

You can use different types of redirect method in laravel -

return redirect()->intended('http://heera.it');

OR

return redirect()->to('http://heera.it');

OR

use Illuminate\Support\Facades\Redirect;

return Redirect::to('/')->with(['type' => 'error','message' => 'Your message'])->withInput(Input::except('password'));

OR

return redirect('/')->with(Auth::logout());

OR

return redirect()->route('user.profile', ['step' => $step, 'id' => $id]);

In an ASP.NET application, I think it goes to the Output or Console window which is visible during debugging.

In my side, it is because POSTMAN setting issue, but I don't know why, maybe I copy a query from other. I simply create a new request in POSTMAN and run it, it works.

When a subscriber unsubscribes you are changing contents of the collection of Subscribers during enumeration.

There are several ways to fix this, one being changing the for loop to use an explicit .ToList():

public void NotifySubscribers(DataRecord sr)  
{
    foreach(Subscriber s in subscribers.Values.ToList())
    {
                                              ^^^^^^^^^  
        ...

That part is now located under Schemes. If you edit your schemes you will see that you can set the debug/release/adhoc/distribution build config for each scheme.

The compiler can't figure out what type to make the Dictionary, because it's not homogenous. You have values of different types. The only way to get around this is to make it a [String: Any], which will make everything clunky as all hell.

return [
    "title": title,
    "is_draft": isDraft,
    "difficulty": difficulty,
    "duration": duration,
    "cost": cost,
    "user_id": userId,
    "description": description,
    "to_sell": toSell,
    "images": [imageParameters, imageToDeleteParameters].flatMap { $0 }
] as [String: Any]

This is a job for a struct. It'll vastly simplify working with this data structure.

Here's a tutorial that shows you how to setup a custom font like @peter described: http://responsiveandroid.com/2012/03/15/custom-fonts-in-android-widgets.html

it also has consideration for potential memory leaks ala http://code.google.com/p/android/issues/detail?id=9904 . Also in the tutorial is an example for setting a custom font on a button.

Others have answered re: time.time() vs. time.clock().

However, if you're timing the execution of a block of code for benchmarking/profiling purposes, you should take a look at the timeit module.

Perform a click on the link to the tab anchor whenever the page is ready i.e.

$('a[href="' + window.location.hash + '"]').trigger('click');

Or in vanilla JavaScript

document.querySelector('a[href="' + window.location.hash + '"]').click();

All of the (text-) files into one

find . | xargs cat > outfile

xargs makes the output-lines of find . the arguments of cat.

find has many options, like -name '*.txt' or -type.

you should check them out if you want to use it in your pipeline

EDIT 2017-05-09: Shorter method added

I developed a shorter method to get the same result, so I couldn't resist to post it here. The two for commands used to separate time parts and the three if commands used to insert leading zeros in the result are replaced by two long arithmetic expressions, that could even be combined into a single longer line.

The method consists in directly convert a variable with a time in "HH:MM:SS.CC" format into the formula needed to convert the time to centiseconds, accordingly to the mapping scheme given below:

       HH        :      MM        :      SS        .       CC

(((10  HH  %%100)*60+1  MM  %%100)*60+1  SS  %%100)*100+1  CC  %%100

That is, insert (((10 at beginning, replace the colons by %%100)*60+1, replace the point by %%100)*100+1 and insert %%100 at end; finally, evaluate the resulting string as an arithmetic expression. In the time variable there are two different substrings that needs to be replaced, so the conversion must be completed in two lines. To get an elapsed time, use (endTime)-(startTime) expression and replace both time strings in the same line.

An even easy way to do it is:

1. Create an animation style into your styles.xml file

<style name="WindowAnimationTransition">
    <item name="android:windowEnterAnimation">@android:anim/fade_in</item>
    <item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>

2. Add this style to your app theme

<style name="AppBaseTheme" parent="Theme.Material.Light.DarkActionBar">
      <item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>
</style>

That's it :)

Thank you for all answers! I found it! It calls "Column selection (for Sublime)" and "Column Mode Editing (for Notepad++)" https://www.sublimetext.com/docs/3/column_selection.html

You can use

git reset

to undo the recently added local files

 git reset file_name

to undo the changes for a specific file

The below code should apply different CSS classes based on your Model's CanEdit Property value .

<div class="@(Model.CanEdit?"visible-item":"hidden-item")">Some links</div>

But if it is something important like Edit/Delete links, you shouldn't be simply hiding,because people can update the css class/HTML markup in their browser and get access to your important link. Instead you should be simply not Rendering the important stuff to the browser.

@if(Model.CanEdit)
{
  <div>Edit/Delete link goes here</div>
}

Apache Commons validator can be used as mentioned in the other answers.

pom.xml:

<dependency>
    <groupId>commons-validator</groupId>
    <artifactId>commons-validator</artifactId>
    <version>1.4.1</version>
</dependency>

build.gradle:

compile 'commons-validator:commons-validator:1.4.1'

The import:

import org.apache.commons.validator.routines.EmailValidator;

The code:

String email = "[email protected]";
boolean valid = EmailValidator.getInstance().isValid(email);

and to allow local addresses

boolean allowLocal = true;
boolean valid = EmailValidator.getInstance(allowLocal).isValid(email);

I found the solution after a few tries, I hope this can help you. Add the following to your <ReactTable> component:

getTrProps={(state, rowInfo) => {
  if (rowInfo && rowInfo.row) {
    return {
      onClick: (e) => {
        this.setState({
          selected: rowInfo.index
        })
      },
      style: {
        background: rowInfo.index === this.state.selected ? '#00afec' : 'white',
        color: rowInfo.index === this.state.selected ? 'white' : 'black'
      }
    }
  }else{
    return {}
  }
}

In your state don't forget to add a null selected value, like:

state = { selected: null }

 "angularCompilerOptions": {
     "fullTemplateTypeCheck": true,
     "strictInjectionParameters": true,
     **"enableIvy": false**
 }

Use ipcs -a: it gives detailed information of all resources [semaphore, shared-memory etc]

I've only found two situations where getBean() was required:

Others have mentioned using getBean() in main() to fetch the "main" bean for a standalone program.

Another use I have made of getBean() are in situations where an interactive user configuration determines the bean makeup for a particular situation. So that, for instance, part of the boot system loops through a database table using getBean() with a scope='prototype' bean definition and then setting additional properties. Presumably, there is a UI that adjusts the database table that would be friendlier than attempting to (re)write the application context XML.

If all your target directories match a path expression — like they're all subdirectories of path/to — then just use find in combination with cp like this:

find ./path/to/* -type d -exec cp [file name] {} \;

That's it.

The simplest way would be to convert your hexadecimal string to a byte array and use the File.WriteAllBytes method.

Using the StringToByteArray() method from this question, you'd do something like this:

string hexString = "0CFE9E69271557822FE715A8B3E564BE";

File.WriteAllBytes("output.dat", StringToByteArray(hexString));

The StringToByteArray method is included below:

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

If multiple characters are bound inside a single integer/long, as was my issue:

s = '0123456789'
nchars = len(s)
# string to int or long. Type depends on nchars
x = sum(ord(s[byte])<<8*(nchars-byte-1) for byte in range(nchars))
# int or long to string
''.join(chr((x>>8*(nchars-byte-1))&0xFF) for byte in range(nchars))

Yields '0123456789' and x = 227581098929683594426425L

$ git remote update
$ git pull --all

This assumes all branches are tracked.

If they aren't you can fire this in Bash:

for remote in `git branch -r `; do git branch --track $remote; done

Then run the command.

I found the same issue with Node 12.19.0 and yarn 1.22.5 on Windows 10. I fixed the problem by installing latest stable python 64-bit with adding the path to Environment Variables during python installation. After python installation, I restarted my machine for env vars.

You need a special type of function known as a table valued function. Below is a somewhat long-winded example that builds a date dimension for a data warehouse. Note the returns clause that defines a table structure. You can insert anything into the table variable (@DateHierarchy in this case) that you want, including building a temporary table and copying the contents into it.

if object_id ('ods.uf_DateHierarchy') is not null
    drop function ods.uf_DateHierarchy
go

create function ods.uf_DateHierarchy (
       @DateFrom datetime
      ,@DateTo   datetime
) returns @DateHierarchy table (

I had the same issue, just opening another terminal with a bash on it worked for me :

create container:

docker run -d mcr.microsoft.com/mssql/server:2019-CTP3.0-ubuntu

start container:

docker start 52bbc9b30557

start bash to keep container running:

docker exec -it 52bbc9b30557 bash

start process you need:

The question is tagged SQL Server 2000 but for the benefit of people developing on the latest version I'll address that first.

SQL Server 2014

In addition to the methods of adding constraint based indexes discussed below SQL Server 2014 also allows non unique indexes to be specified directly with inline syntax on table variable declarations.

Example syntax for that is below.

/*SQL Server 2014+ compatible inline index syntax*/
DECLARE @T TABLE (
C1 INT INDEX IX1 CLUSTERED, /*Single column indexes can be declared next to the column*/
C2 INT INDEX IX2 NONCLUSTERED,
       INDEX IX3 NONCLUSTERED(C1,C2) /*Example composite index*/
);

Filtered indexes and indexes with included columns can not currently be declared with this syntax however SQL Server 2016 relaxes this a bit further. From CTP 3.1 it is now possible to declare filtered indexes for table variables. By RTM it may be the case that included columns are also allowed but the current position is that they "will likely not make it into SQL16 due to resource constraints"

/*SQL Server 2016 allows filtered indexes*/
DECLARE @T TABLE
(
c1 INT NULL INDEX ix UNIQUE WHERE c1 IS NOT NULL /*Unique ignoring nulls*/
)

SQL Server 2000 - 2012

Can I create a index on Name?

Short answer: Yes.

DECLARE @TEMPTABLE TABLE (
  [ID]   [INT] NOT NULL PRIMARY KEY,
  [Name] [NVARCHAR] (255) COLLATE DATABASE_DEFAULT NULL,
  UNIQUE NONCLUSTERED ([Name], [ID]) 
  ) 

A more detailed answer is below.

Traditional tables in SQL Server can either have a clustered index or are structured as heaps.

Clustered indexes can either be declared as unique to disallow duplicate key values or default to non unique. If not unique then SQL Server silently adds a uniqueifier to any duplicate keys to make them unique.

Non clustered indexes can also be explicitly declared as unique. Otherwise for the non unique case SQL Server adds the row locator (clustered index key or RID for a heap) to all index keys (not just duplicates) this again ensures they are unique.

In SQL Server 2000 - 2012 indexes on table variables can only be created implicitly by creating a UNIQUE or PRIMARY KEY constraint. The difference between these constraint types are that the primary key must be on non nullable column(s). The columns participating in a unique constraint may be nullable. (though SQL Server's implementation of unique constraints in the presence of NULLs is not per that specified in the SQL Standard). Also a table can only have one primary key but multiple unique constraints.

Both of these logical constraints are physically implemented with a unique index. If not explicitly specified otherwise the PRIMARY KEY will become the clustered index and unique constraints non clustered but this behavior can be overridden by specifying CLUSTERED or NONCLUSTERED explicitly with the constraint declaration (Example syntax)

DECLARE @T TABLE
(
A INT NULL UNIQUE CLUSTERED,
B INT NOT NULL PRIMARY KEY NONCLUSTERED
)

As a result of the above the following indexes can be implicitly created on table variables in SQL Server 2000 - 2012.

+-------------------------------------+-------------------------------------+
|             Index Type              | Can be created on a table variable? |
+-------------------------------------+-------------------------------------+
| Unique Clustered Index              | Yes                                 |
| Nonunique Clustered Index           |                                     |
| Unique NCI on a heap                | Yes                                 |
| Non Unique NCI on a heap            |                                     |
| Unique NCI on a clustered index     | Yes                                 |
| Non Unique NCI on a clustered index | Yes                                 |
+-------------------------------------+-------------------------------------+

The last one requires a bit of explanation. In the table variable definition at the beginning of this answer the non unique non clustered index on Name is simulated by a unique index on Name,Id (recall that SQL Server would silently add the clustered index key to the non unique NCI key anyway).

A non unique clustered index can also be achieved by manually adding an IDENTITY column to act as a uniqueifier.

DECLARE @T TABLE
(
A INT NULL,
B INT NULL,
C INT NULL,
Uniqueifier INT NOT NULL IDENTITY(1,1),
UNIQUE CLUSTERED (A,Uniqueifier)
)

But this is not an accurate simulation of how a non unique clustered index would normally actually be implemented in SQL Server as this adds the "Uniqueifier" to all rows. Not just those that require it.

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root
    ports:
     - "3306:3306"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5

  apigw-tomcat:
    container_name: apigw-tomcat
    build: tomcat/.
    ports:
     - "8080:8080"
     - "8009:8009"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.6
    depends_on:
     - mysql

networks:
  vpcbr:
    driver: bridge
    ipam:
     config:
       - subnet: 10.5.0.0/16
         gateway: 10.5.0.1

string Index = i;
            string FileName = "Mutton" + Index + ".xml";
            XmlDocument xmlDoc = new XmlDocument();

            var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
            xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);

this is the best Solution to get the path what is exactly need for now

Jackson appears to support some amount of JSON parsing straight from an InputStream. My understanding is that it runs on Android and is fairly quick. On the other hand, it is an extra JAR to include with your app, increasing download and on-flash size.

The class pull-right is still there in Bootstrap 3 See the 'helper classes' here

pull-right is defined by

.pull-right {
  float: right !important;
}

without more info on styles and content, it's difficult to say.

It definitely pulls right in this JSBIN when the page is wider than 990px - which is when the col-md styling kicks in, Bootstrap 3 being mobile first and all.

Bootstrap 4

Note that for Bootstrap 4 .pull-right has been replaced with .float-right https://www.geeksforgeeks.org/pull-left-and-pull-right-classes-in-bootstrap-4/#:~:text=pull%2Dright%20classes%20have%20been,based%20on%20the%20Bootstrap%20Grid.

import re
word = 'fubar'
regexp = re.compile(r'ba[rzd]')
if regexp.search(word):
  print 'matched'

Since Bootstrap v4.1 you can add table-borderless to your table, see official documentation:

<table class='table table-borderless'>

Parallel.ForEach will optimize(may not even start new threads) and block until the loop is finished, and Task.Factory will explicitly create a new task instance for each item, and return before they are finished (asynchronous tasks). Parallel.Foreach is much more efficient.

start -> CMD -> (Write comand) SQLCMD -L first line is Server name if Server name is (local) Server name is : YourPcName\SQLEXPRESS

Consider time and space complexity both. For Merge sort : Time complexity : O(nlogn) , Space complexity : O(nlogn)

For Quick sort : Time complexity : O(n^2) , Space complexity : O(n)

Now, they both win in one scenerio each. But, using a random pivot you can almost always reduce Time complexity of Quick sort to O(nlogn).

Thus, Quick sort is preferred in many applications instead of Merge sort.

playSound is a static method meaning it exists when the program is loaded. audioSounds and minTime are SoundManager instance variable, meaning they will exist within an instance of SoundManager. You have not created an instance of SoundManager so audioSounds doesn't exist (or it does but you do not have a reference to a SoundManager object to see that).

To solve your problem you can either make audioSounds static:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

so they will be created and may be referenced in the same way that PlaySound will be. Alternatively you can create an instance of SoundManager from within your method:

SoundManager soundManager = new SoundManager();
foreach (AudioSource sound in soundManager.audioSounds) // Loop through List with foreach
{
    if (sourceSound.name != sound.name && sound.time <= soundManager.minTime)
    {
        playsound = true;
    }
}

You can import the lib org.apache.commons.lang.ArrayUtils

There is a static method where you can pass in an int array and a value to check for.

contains(int[] array, int valueToFind) Checks if the value is in the given array.

ArrayUtils.contains(intArray, valueToFind);

<div  id="my_id" class="my_class"></div>

if that is the first div then address it like so:

document.write("div CSS class: " + document.getElementsByTagName('div')[0].className);

alternatively do this:

document.write("alternative way: " + document.getElementById('my_id').className);

It yields the following results:

div CSS class: my_class
alternative way: my_class

The method I prefer assigns an array of data to the combobox. Click on the body of your userform and change the "Click" event to "Initialize". Now the combobox will fill upon the initializing of the userform. I hope this helps.

Sub UserForm_Initialize()
  ComboBox1.List = Array("1001", "1002", "1003", "1004", "1005", "1006", "1007", "1008", "1009", "1010")
End Sub

I just used :first as CSS selector successfully.

Here's a way to get dimensions of a png file without needing a third-party module. From http://coreygoldberg.blogspot.com/2013/01/python-verify-png-file-and-get-image.html

import struct

def get_image_info(data):
    if is_png(data):
        w, h = struct.unpack('>LL', data[16:24])
        width = int(w)
        height = int(h)
    else:
        raise Exception('not a png image')
    return width, height

def is_png(data):
    return (data[:8] == '\211PNG\r\n\032\n'and (data[12:16] == 'IHDR'))

if __name__ == '__main__':
    with open('foo.png', 'rb') as f:
        data = f.read()

    print is_png(data)
    print get_image_info(data)

When you run this, it will return:

True
(x, y)

Sub ReverseOrderLegends()

mChartName = "Chart 1"
Dim sSeriesCollection As SeriesCollection
Dim mSeries As Series
With ActiveSheet
    .ChartObjects(mChartName).Chart.SetElement (msoElementLegendNone)
    .ChartObjects(mChartName).Chart.SetElement (msoElementLegendRight)
    Set sSeriesCollection = .ChartObjects(mChartName).Chart.SeriesCollection
    For Each mSeries In sSeriesCollection
        If mSeries.Values(1) = 0.000000123 Or mSeries.Values(1) = Empty Then
            mSeries.Delete
        End If
    Next mSeries

    LegendCount = .ChartObjects(mChartName).Chart.SeriesCollection.Count
    For mLegend = 1 To LegendCount
        .ChartObjects(mChartName).Chart.SeriesCollection.NewSeries
        .ChartObjects(mChartName).Chart.SeriesCollection(LegendCount + mLegend).Name = .ChartObjects(mChartName).Chart.SeriesCollection(LegendCount - mLegend + 1).Name
        .ChartObjects(mChartName).Chart.SeriesCollection(LegendCount + mLegend).Values = "={0.000000123}"
        .ChartObjects(mChartName).Chart.SeriesCollection(LegendCount + mLegend).Format.Fill.ForeColor.RGB = .ChartObjects(mChartName).Chart.SeriesCollection(LegendCount - mLegend + 1).Format.Fill.ForeColor.RGB
    Next mLegend

    For mLegend = 1 To LegendCount
        .ChartObjects(mChartName).Chart.Legend.LegendEntries(1).Delete
    Next mLegend
End With
End Sub

If you also get the key, you can delete that item like this:

foreach ($display_related_tags as $key => $tag_name) {
    if($tag_name == $found_tag['name']) {
        unset($display_related_tags[$key]);
    }
}

I'll throw this in as an alternative just for the heck of it, even though it's pretty much useless when compared to " ".join(my_list) for strings. For non-strings (such as an array of ints) this may be better:

" ".join(str(item) for item in my_list)

you need to return when the readystate==4 e.g.

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            return xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET", theUrl, false );
    xmlhttp.send();    
}

Here is another way I figured it out:

const x = this.dealer;
switch (true) {
    case (x < 5):
        alert("less than five");
        break;
    case (x < 9):
        alert("between 5 and 8");
        break;
    case (x < 12):
        alert("between 9 and 11");
        break;
    default:
        alert("none");
        break;
}

info = data[:min(len(data), 75)

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }
}

The following might be helpful for RecyclerView with Single Choice.

Three steps to do that, 1) Declare a global integer variable,

private int mSelectedItem = -1;

2) in onBindViewHolder

 mRadio.setChecked(position == mSelectedItem);

3) in onClickListener

mSelectedItem = getAdapterPosition();
notifyItemRangeChanged(0, mSingleCheckList.size());
mAdapter.onItemHolderClick(SingleCheckViewHolder.this);

in your view, instead of:

@Html.EditorFor(model => model.Comments[0].Comment)

just use:

@Html.TextAreaFor(model => model.Comments[0].Comment, 5, 1, null)

The System.Math.Round method uses the Double structure, which, as others have pointed out, is prone to floating point precision errors. The simple solution I found to this problem when I encountered it was to use the System.Decimal.Round method, which doesn't suffer from the same problem and doesn't require redifining your variables as decimals:

Decimal.Round(0.575, 2, MidpointRounding.AwayFromZero)

Result: 0.58

strip removes the whitespace from the beginning and end of the string. If you want the whitespace, don't call strip.

change the focused border to none

TextField(
      decoration: new InputDecoration(
          border: InputBorder.none,
          focusedBorder: InputBorder.none,
          contentPadding: EdgeInsets.only(left: 15, bottom: 11, top: 11, right: 15),
          hintText: 'Subject'
      ),
    ),

Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...

LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.

I just learned this trick from a friend. Put your code inside these 2 statements and it will be commented out.

#if false

#endif

If Install before Mongodb Just Start with this code :

brew services start mongodb-community
next => mongod

If Not Install before this Way

1.brew tap mongodb/brew
2.brew install mongodb-community
3.brew services start mongodb-community
4.mongod

Both answers are in the ballpark but neither is a complete answer.

MyClass.class.isInstance(obj) is for checking an instance. It returns true when the parameter obj is non-null and can be cast to MyClass without raising a ClassCastException. In other words, obj is an instance of MyClass or its subclasses.

MyClass.class.isAssignableFrom(Other.class) will return true if MyClass is the same as, or a superclass or superinterface of, Other. Other can be a class or an interface. It answers true if Other can be converted to a MyClass.

A little code to demonstrate:

public class NewMain
{
    public static void main(String[] args)
    {
        NewMain nm = new NewMain();
        nm.doit();
    }

    class A { }

    class B extends A { }

    public void doit()
    {
        A myA = new A();
        B myB = new B();
        A[] aArr = new A[0];
        B[] bArr = new B[0];

        System.out.println("b instanceof a: " + (myB instanceof A)); // true
        System.out.println("b isInstance a: " + A.class.isInstance(myB)); //true
        System.out.println("a isInstance b: " + B.class.isInstance(myA)); //false
        System.out.println("b isAssignableFrom a: " + A.class.isAssignableFrom(B.class)); //true
        System.out.println("a isAssignableFrom b: " + B.class.isAssignableFrom(A.class)); //false
        System.out.println("bArr isInstance A: " + A.class.isInstance(bArr)); //false
        System.out.println("bArr isInstance aArr: " + aArr.getClass().isInstance(bArr)); //true
        System.out.println("bArr isAssignableFrom aArr: " + aArr.getClass().isAssignableFrom(bArr.getClass())); //true
    }
}

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

I believe this would be somewhere close.

INSERT INTO Files
(FileId, FileData)
SELECT 1, * FROM OPENROWSET(BULK N'C:\Image.jpg', SINGLE_BLOB) rs

Something to note, the above runs in SQL Server 2005 and SQL Server 2008 with the data type as varbinary(max). It was not tested with image as data type.

I got it!...hehe

protected DataTable RetrieveEmployeeSubInfo(string employeeNo)
        {
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            DataTable dt = new DataTable();
            try
            {
                cmd = new SqlCommand("RETRIEVE_EMPLOYEE", pl.ConnOpen());
                cmd.Parameters.Add(new SqlParameter("@EMPLOYEENO", employeeNo));
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(dt);
                dataGridView1.DataSource = dt;
            }
            catch (Exception x)
            {
                MessageBox.Show(x.GetBaseException().ToString(), "Error",
                        MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
                cmd.Dispose();
                pl.MySQLConn.Close();
            }
            return dt;
        }

I ran into the same issue today, try running ur container with this command.

docker run --name mariadbtest -p 3306:3306 -e MYSQL_ROOT_PASSWORD=mypass -d mariadb/server:10.3

As a kind of simple solution you can use temp TreeMap if you need just a final result:

TreeMap<String, Integer> sortedMap = new TreeMap<String, Integer>();
for (Map.Entry entry : map.entrySet()) {
    sortedMap.put((String) entry.getValue(), (Integer)entry.getKey());
}

This will get you strings sorted as keys of sortedMap.

You have to style the image like this

#container img{width:100%;}

and the container with hidden overflow:

#container{width:250px; height:250px; overflow:hidden; border:1px solid #000;} 

If you are trying to decode a web image you can simply use this :

import base64

with open("imageToSave.png", "wb") as fh:
  fh.write(base64.urlsafe_b64decode('data'))

data => is the encoded string

It will take care of the padding errors

Do a query:

SELECT * FROM v$session s;

Find your user and do the next query (with appropriate parameters):

ALTER SYSTEM KILL SESSION '<SID>, <SERIAL>';

Many answers here are good and pretty easy. But if your array of object is having a fixed set of value then you can use below trick:

Map all the name in a object.

vendors = [
    {
      Name: 'Magenic',
      ID: 'ABC'
     },
    {
      Name: 'Microsoft',
      ID: 'DEF'
    }
];

var dirtyObj = {}
for(var count=0;count<vendors.length;count++){
   dirtyObj[vendors[count].Name] = true //or assign which gives you true.
}

Now this dirtyObj you can use again and again without any loop.

if(dirtyObj[vendor.Name]){
  console.log("Hey! I am available.");
}

.eq() -An integer indicating the 0-based position of the element.

Ex:

Consider a page with a simple list on it:

<ul>
<li>list item 1</li>
<li>list item 2</li>
<li>list item 3</li>
<li>list item 4</li>
</ul>

We can apply this method to the set of list items:

$( "li" ).eq( 2 ).css( "background-color", "red" );

For more information : .eq()

The difference is that recv()/send() work only on socket descriptors and let you specify certain options for the actual operation. Those functions are slightly more specialized (for instance, you can set a flag to ignore SIGPIPE, or to send out-of-band messages...).

Functions read()/write() are the universal file descriptor functions working on all descriptors.

This is a change made with Java 1.5. What you list first is the old way, the second is the new way.

By using HashMap you can do things like:

HashMap<String, Doohickey> ourMap = new HashMap<String, Doohickey>();

....

Doohickey result = ourMap.get("bob");

If you didn't have the types on the map, you'd have to do this:

Doohickey result = (Doohickey) ourMap.get("bob");

It's really very useful. It helps you catch bugs and avoid writing all sorts of extra casts. It was one of my favorite features of 1.5 (and newer).

You can still put multiple things in the map, just specify it as Map, then you can put any object in (a String, another Map, and Integer, and three MyObjects if you are so inclined).

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'database_name';

This was the first i tried

skilla:~# uniq -u all.sorted  

76679787
76679787 
76794979
76794979 
76869286
76869286 
......

After doing a cat -e all.sorted

skilla:~# cat -e all.sorted 
$
76679787$
76679787 $
76701427$
76701427$
76794979$
76794979 $
76869286$
76869286 $

Every second line has a trailing space :( After removing all trailing spaces it worked!

thank you

Here is an example:

>>> u = u'€€€'
>>> s = u.encode('utf8')
>>> s
'\xe2\x82\xac\xe2\x82\xac\xe2\x82\xac'

The C++ way of solving conversions (not the classical C) is illustrated with the program below. Note that the intent is to be able to use the same formatting facilities offered by iostream like precision, fill character, padding, hex, and the manipulators, etcetera.

Compile and run this program, then study it. It is simple

#include "iostream"
#include "iomanip"
#include "sstream"
using namespace std;

int main()
{
    // Converting the content of a char array or a string to a double variable
    double d;
    string S;
    S = "4.5";
    istringstream(S) >> d;    
    cout << "\nThe value of the double variable d is " << d << endl;
    istringstream("9.87654") >> d;  
    cout << "\nNow the value of the double variable d is " << d << endl;



    // Converting a double to string with formatting restrictions
    double D=3.771234567;

    ostringstream Q;
    Q.fill('#');
    Q << "<<<" << setprecision(6) << setw(20) << D << ">>>";
    S = Q.str(); // formatted converted double is now in string 

    cout << "\nThe value of the string variable S is " << S << endl;
    return 0;
}

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

No need for external plugins. In the Export JAR dialog, make sure you select all the necessary resources you want to export. By default, there should be no problem exporting other resource files as well (pictures, configuration files, etc...), see screenshot below.

These are the changes since python 2:

    try:
        1 / 0
    except Exception as e: # (as opposed to except Exception, e:)
                           # ^ that will just look for two classes, Exception and e
        # for the repr
        print(repr(e))
        # for just the message, or str(e), since print calls str under the hood
        print(e)
        # the arguments that the exception has been called with. 
        # the first one is usually the message. (OSError is different, though)
        print(e.args)

You can look into the standard library module traceback for fancier stuff.

A Bash function can't return a string directly like you want it to. You can do three things:

1. Echo a string
2. Return an exit status, which is a number, not a string
3. Share a variable

This is also true for some other shells.

Here's how to do each of those options:

1. Echo strings

lockdir="somedir"
testlock(){
    retval=""
    if mkdir "$lockdir"
    then # Directory did not exist, but it was created successfully
         echo >&2 "successfully acquired lock: $lockdir"
         retval="true"
    else
         echo >&2 "cannot acquire lock, giving up on $lockdir"
         retval="false"
    fi
    echo "$retval"
}

retval=$( testlock )
if [ "$retval" == "true" ]
then
     echo "directory not created"
else
     echo "directory already created"
fi

2. Return exit status

lockdir="somedir"
testlock(){
    if mkdir "$lockdir"
    then # Directory did not exist, but was created successfully
         echo >&2 "successfully acquired lock: $lockdir"
         retval=0
    else
         echo >&2 "cannot acquire lock, giving up on $lockdir"
         retval=1
    fi
    return "$retval"
}

testlock
retval=$?
if [ "$retval" == 0 ]
then
     echo "directory not created"
else
     echo "directory already created"
fi

3. Share variable

lockdir="somedir"
retval=-1
testlock(){
    if mkdir "$lockdir"
    then # Directory did not exist, but it was created successfully
         echo >&2 "successfully acquired lock: $lockdir"
         retval=0
    else
         echo >&2 "cannot acquire lock, giving up on $lockdir"
         retval=1
    fi
}

testlock
if [ "$retval" == 0 ]
then
     echo "directory not created"
else
     echo "directory already created"
fi

Don't use UTF-8 encoding. Standard FPDF fonts use ISO-8859-1 or Windows-1252. It is possible to perform a conversion to ISO-8859-1 with utf8_decode(): $str = utf8_decode($str); But some characters such as Euro won't be translated correctly. If the iconv extension is available, the right way to do it is the following: $str = iconv('UTF-8', 'windows-1252', $str);

I have a 645GB text file, and none of the earlier exact solutions (e.g. wc -l) returned an answer within 5 minutes.

Instead, here is Python script that computes the approximate number of lines in a huge file. (My text file apparently has about 5.5 billion lines.) The Python script does the following:

A. Counts the number of bytes in the file.

B. Reads the first N lines in the file (as a sample) and computes the average line length.

C. Computes A/B as the approximate number of lines.

It follows along the line of Nico's answer, but instead of taking the length of one line, it computes the average length of the first N lines.

Note: I'm assuming an ASCII text file, so I expect the Python len() function to return the number of chars as the number of bytes.

Put this code into a file line_length.py:

#!/usr/bin/env python

# Usage:
# python line_length.py <filename> <N> 

import os
import sys
import numpy as np

if __name__ == '__main__':

    file_name = sys.argv[1]
    N = int(sys.argv[2]) # Number of first lines to use as sample.
    file_length_in_bytes = os.path.getsize(file_name)
    lengths = [] # Accumulate line lengths.
    num_lines = 0

    with open(file_name) as f:
        for line in f:
            num_lines += 1
            if num_lines > N:
                break
            lengths.append(len(line))

    arr = np.array(lengths)
    lines_count = len(arr)
    line_length_mean = np.mean(arr)
    line_length_std = np.std(arr)

    line_count_mean = file_length_in_bytes / line_length_mean

    print('File has %d bytes.' % (file_length_in_bytes))
    print('%.2f mean bytes per line (%.2f std)' % (line_length_mean, line_length_std))
    print('Approximately %d lines' % (line_count_mean))

Invoke it like this with N=5000.

% python line_length.py big_file.txt 5000

File has 645620992933 bytes.
116.34 mean bytes per line (42.11 std)
Approximately 5549547119 lines

So there are about 5.5 billion lines in the file.

Instead of Str(RequestID), try convert(varchar(38), RequestID)

pygame is not distributed via pip. See this link which provides windows binaries ready for installation.

1. Install python
2. Make sure you have python on your PATH
3. Download the appropriate wheel from this link
4. Install pip using this tutorial

5. Finally, use these commands to install pygame wheel with pip

   • Python 2 (usually called pip)

     • pip install file.whl

   • Python 3 (usually called pip3)

     • pip3 install file.whl

Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit

Looks like the invisible character -

ALT+255

Try this

select REPLACE(ProductAlternateKey, ' ', '@')
--type ALT+255 instead of space for the second expression in REPLACE 
from DimProducts
where ProductAlternateKey  like '46783815%'

Edit: Based on ASCII() results, try ALT+10 - use numeric keypad

There is no exists for a SCALAR in Perl, anyway. The Perl way is

defined( $x ) 

and the equivalent Java is

anInteger != null

Those are the equivalents.

exists $hash{key}

Is like the Java

map.containsKey( "key" )

From your example, I think you're looking for

if ( startIn != null ) { ...

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

The password_hash() function in PHP is an inbuilt function , used to create a new password hash with different algorithms and options. the function uses a strong hashing algorithm.

the function take 2 mandetory parametres ($password and $algorithm,) and 1 optional parameter ($options).

$strongPassword = password_hash( $password, $algorithm, $options )

Algoristrong textthms allowed right now for password_hash() are :

• PASSWORD_DEFAULT

• PASSWORD_BCRYPT

• ASSWORD_ARGON2I

• PASSWORD_ARGON2ID

example : echo password_hash("abcDEF", PASSWORD_DEFAULT);

answer :$2y$10$SNly5bFzB/R6OVbBMq1bj.yiOZdsk6Mwgqi4BLR2sqdCvMyv/AyL2

to use the BCRYPT as password, use option cost =12 in an array , also change 1st parameter $password to some strong password like "wgt167yuWBGY@#1987__"

Example: echo password_hash("wgt167yuWBGY@#1987__", PASSWORD_BCRYPT ,['cost' => 12]);
