shape is a tuple that gives dimensions of the array..

>>> c = arange(20).reshape(5,4)
>>> c
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11],
       [12, 13, 14, 15],
       [16, 17, 18, 19]])

c.shape[0] 
5

Gives the number of rows

c.shape[1] 
4

Gives number of columns

There is a trick you can do for Outlook 2007 using conditional html comments.
The code below will make sure that Outlook table is 800px wide, its not max-width but it works better than letting the table span across the entire window.

<!--[if gte mso 9]>
<style>
#tableForOutlook {
  width:800px;
}
</style>
<![endif]-->

<table style="width:98%;max-width:800px">
<!--[if gte mso 9]>
  <table id="tableForOutlook"><tr><td>
<![endif]-->
    <tr><td>
    [Your Content Goes Here]
    </td></tr>
<!--[if gte mso 9]>
  </td></tr></table>
<![endif]-->
<table>

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

You're trying to do &(2), &(4) which won't work

#romtest {
  .detailed {
    th {
      &:nth-child(2) {//your styles here}
      &:nth-child(4) {//your styles here}
      &:nth-child(6) {//your styles here}
      }
  }
}

It seems that you are right. No option scales the image better:
http://www.maxrev.de/html/image-scaling.html

I've tested FF14, IE9, OP12 and GC21. Only GC has a better scaling that can be deactivated through image-rendering: -webkit-optimize-contrast. All other browsers have no/poor scaling.

Screenshot of the different output: http://www.maxrev.de/files/2012/08/screenshot_interpolation_jquery_animate.png

Update 2017

Meanwhile some more browsers support smooth scaling:

• ME38 (Microsoft Edge) has good scaling. It can't be disabled and it works for JPEG and PNG, but not for GIF.

• FF51 (Regarding @karthik 's comment since FF21) has good scaling that can be disabled through the following settings:

  image-rendering: optimizeQuality
  image-rendering: optimizeSpeed
  image-rendering: -moz-crisp-edges
  

  Note: Regarding MDN the optimizeQuality setting is a synonym for auto (but auto does not disable smooth scaling):

  The values optimizeQuality and optimizeSpeed present in early draft (and coming from its SVG counterpart) are defined as synonyms for the auto value.

• OP43 behaves like GC (not suprising as it is based on Chromium since 2013) and its still this option that disables smooth scaling:

  image-rendering: -webkit-optimize-contrast
  

No support in IE9-IE11. The -ms-interpolation-mode setting worked only in IE6-IE8, but was removed in IE9.

P.S. Smooth scaling is done by default. This means no image-rendering option is needed!

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

A simple route 4 / 100.0

or

4.0 / 100

Yes, await / async was a great concept, but the implementation is completely broken.

For whatever reason, the await keyword has been implemented such that it can only be used within an async method. This is in fact a bug, though you will not see it referred to as such anywhere but right here. The fix for this bug would be to implement the await keyword such that it can only be used TO CALL an async function, regardless of whether the calling function is itself synchronous or asynchronous.

Due to this bug, if you use await to call a real asynchronous function somewhere in your code, then ALL of your functions must be marked as async and ALL of your function calls must use await.

This essentially means that you must add the overhead of promises to all of the functions in your entire application, most of which are not and never will be asynchronous.

If you actually think about it, using await in a function should require the function containing the await keyword TO NOT BE ASYNC - this is because the await keyword is going to pause processing in the function where the await keyword is found. If processing in that function is paused, then it is definitely NOT asynchronous.

So, to the developers of javascript and ECMAScript - please fix the await/async implementation as follows...

• await can only be used to CALL async functions.
• await can appear in any kind of function, synchronous or asynchronous.
• Change the error message from "await is only valid in async function" to "await can only be used to call async functions".

You can use the sort command:

sort -k2 -n yourfile

-n, --numeric-sort compare according to string numerical value

For example:

$ cat ages.txt 
Bob 12
Jane 48
Mark 3
Tashi 54

$ sort -k2 -n ages.txt 
Mark 3
Bob 12
Jane 48
Tashi 54

use this attribute in style

font-size: 11px !important;//your font size

by !important it override your css

My prefer solution is Microsoft KB 111401 http://support.microsoft.com/kb/111401.

The link refers to 3 examples:

This article describes various methods that you can use to simulate a cursor-like FETCH-NEXT logic in a stored procedure, trigger, or Transact-SQL batch.

/*********** example 1 ***********/ 

declare @au_id char( 11 )

set rowcount 0
select * into #mytemp from authors

set rowcount 1

select @au_id = au_id from #mytemp

while @@rowcount <> 0
begin
    set rowcount 0
    select * from #mytemp where au_id = @au_id
    delete #mytemp where au_id = @au_id

    set rowcount 1
    select @au_id = au_id from #mytemp
end
set rowcount 0



/********** example 2 **********/ 

declare @au_id char( 11 )

select @au_id = min( au_id ) from authors

while @au_id is not null
begin
    select * from authors where au_id = @au_id
    select @au_id = min( au_id ) from authors where au_id > @au_id
end



/********** example 3 **********/ 

set rowcount 0

set rowcount 1
update #mytemp set mykey = 1

while @@rowcount > 0
begin
    set rowcount 0
    select * from #mytemp where mykey = 1
    delete #mytemp where mykey = 1
    set rowcount 1
    update #mytemp set mykey = 1
end
set rowcount 0

Could not get this to work until I put Authorization in single quotes:

axios.get(URL, { headers: { 'Authorization': AuthStr } })

There is a good solution to this issue:

import com.fasterxml.jackson.databind.ObjectMapper;

ObjectMapper objectMapper = new ObjectMapper();

***DTO premierDriverInfoDTO = objectMapper.convertValue(jsonString, ***DTO.class); 

Map<String, String> map = objectMapper.convertValue(jsonString, Map.class);

Why did this issue occur? I guess you didn't specify the specific type when converting a string to the object, which is a class with a generic type, such as, User <T>.

Maybe there is another way to solve it, using Gson instead of ObjectMapper. (or see here Deserializing Generic Types with GSON)

Gson gson = new GsonBuilder().create();

Type type = new TypeToken<BaseResponseDTO<List<PaymentSummaryDTO>>>(){}.getType();

BaseResponseDTO<List<PaymentSummaryDTO>> results = gson.fromJson(jsonString, type);

BigDecimal revenue = results.getResult().get(0).getRevenue();

This is what you want

function isANumber(str){
  return !/\D/.test(str);
}

you can use CASE

SELECT   ...,
         CASE WHEN IDParent < 1 THEN ID ELSE IDPArent END AS ColumnName,
         ...
FROM     tableName

I tried the below solution and it work fine for me.

/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/

Tried below phone format:

• +(123) 456 7899
• (123) 456 7899
• (123).456.7899
• (123)-456-7899
• 123-456-7899
• 123 456 7899
• 1234567899

There is a pseudocolumn called %%physloc%% that shows the physical address of the row.

See Equivalent of Oracle's RowID in SQL Server

It is also possible to load scripts and links into the header. I'll be adding it one of the examples above...

<!--load_essentials.js-->
document.write('<link rel="stylesheet" type="text/css" href="css/style.css" />');
document.write('<link rel="stylesheet" type="text/css" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />');
document.write('<script src="js/jquery.js" type="text/javascript"></script>');

document.getElementById("myHead").innerHTML =
"<span id='headerText'>Title</span>"
+ "<span id='headerSubtext'>Subtitle</span>";
document.getElementById("myNav").innerHTML =
"<ul id='navLinks'>"
+ "<li><a href='index.html'>Home</a></li>"
+ "<li><a href='about.html'>About</a>"
+ "<li><a href='donate.html'>Donate</a></li>"
+ "</ul>";
document.getElementById("myFooter").innerHTML =
"<p id='copyright'>Copyright &copy; " + new Date().getFullYear() + " You. All"
+ " rights reserved.</p>"
+ "<p id='credits'>Layout by You</p>"
+ "<p id='contact'><a href='mailto:[email protected]'>Contact Us</a> / "
+ "<a href='mailto:[email protected]'>Report a problem.</a></p>";

<!--HTML-->
<header id="myHead"></header>

<script src="load_essentials.js"></script>

They do behave differently when the value is null.

• null.toString() throws an error - Cannot call method 'toString' of null
• String(null) returns - "null"
• null + "" also returns - "null"

Very similar behaviour happens if value is undefined (see jbabey's answer).

Other than that, there is a negligible performance difference, which, unless you're using them in huge loops, isn't worth worrying about.

Open Windows PowerShell, and use the below command:

Get-FileHash C:\Users\Deepak\Downloads\ubuntu-20.10-desktop-amd64.iso

As Sagi stated in their answer DataTable.Load is a good solution. If you are trying to load multiple tables from a single reader you do not need to call DataReader.NextResult. The DataTable.Load method also advances the reader to the next result set (if any).

// Read every result set in the data reader.
while (!reader.IsClosed)
{
    DataTable dt = new DataTable();
    // DataTable.Load automatically advances the reader to the next result set
    dt.Load(reader);
    items.Add(dt);
}

For Xamarin.iOS you can use the following code to get contents of the file if file exists.

var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "xyz.json");
if (File.Exists(filename))
{
var text =System.IO.File.ReadAllText(filename);
}

Strange but true: if acceptable (i.e. result is void and you don't mind letting the runloop cycle once), add a delay, even if this is zero:

[_controller performSelector:NSSelectorFromString(@"someMethod")
    withObject:nil
    afterDelay:0];

This removes the warning, presumably because it reassures the compiler that no object can be returned and somehow mismanaged.

I had the same issue and I needed an algorithm using a config file. In This way you can use multiple fields define by a configuration file (simulate just by a List<String) config)

  public static void test() {  
    // Associate your configName with your Comparator 
    Map<String, Comparator<DocumentDto>> map = new HashMap<>();
    map.put("id", new IdSort());
    map.put("createUser", new DocumentUserSort());
    map.put("documentType", new DocumentTypeSort());
    /**
      In your config.yml file, you'll have something like
      sortlist: 
        - documentType
        - createUser
        - id
    */
    List<String> config = new ArrayList<>();
    config.add("documentType");
    config.add("createUser");
    config.add("id");
    

    List<Comparator<DocumentDto>> sorts = new ArrayList<>();

    for (String comparator : config) {
        sorts.add(map.get(comparator));
    }

    // Begin creation of the list 
    DocumentDto d1 = new DocumentDto();
    d1.setDocumentType(new DocumentTypeDto());
    d1.getDocumentType().setCode("A");
    d1.setId(1);
    d1.setCreateUser("Djory");

    DocumentDto d2 = new DocumentDto();
    d2.setDocumentType(new DocumentTypeDto());
    d2.getDocumentType().setCode("A");
    d2.setId(2);
    d2.setCreateUser("Alex");

    DocumentDto d3 = new DocumentDto();
    d3.setDocumentType(new DocumentTypeDto());
    d3.getDocumentType().setCode("A");
    d3.setId(3);
    d3.setCreateUser("Djory");

    DocumentDto d4 = new DocumentDto();
    d4.setDocumentType(new DocumentTypeDto());
    d4.getDocumentType().setCode("A");
    d4.setId(4);
    d4.setCreateUser("Alex");

    DocumentDto d5 = new DocumentDto();
    d5.setDocumentType(new DocumentTypeDto());
    d5.getDocumentType().setCode("D");
    d5.setId(5);
    d5.setCreateUser("Djory");

    DocumentDto d6 = new DocumentDto();
    d6.setDocumentType(new DocumentTypeDto());
    d6.getDocumentType().setCode("B");
    d6.setId(6);
    d6.setCreateUser("Alex");

    DocumentDto d7 = new DocumentDto();
    d7.setDocumentType(new DocumentTypeDto());
    d7.getDocumentType().setCode("B");
    d7.setId(7);
    d7.setCreateUser("Alex");

    List<DocumentDto> documents = new ArrayList<>();

    documents.add(d1);
    documents.add(d2);
    documents.add(d3);
    documents.add(d4);
    documents.add(d5);
    documents.add(d6);
    documents.add(d7);
    // End creation of the list


    // The Sort 
    Stream<DocumentDto> docStream = documents.stream();

    // we need to reverse this list in order to sort by documentType first because stream are pull-based, last sorted() will have the priority
    Collections.reverse(sorts);

    for(Comparator<DocumentDto> entitySort : sorts){
        docStream = docStream.sorted(entitySort);
    }
    documents = docStream.collect(Collectors.toList());
    // documents has been sorted has you configured
    // in case of equality second sort will be used.

    System.out.println(documents);

  }

Comparator objects are really simple.

public class IdSort implements Comparator<DocumentDto> {

    @Override
    public int compare(DocumentDto o1, DocumentDto o2) {
        return o1.getId().compareTo(o2.getId());
    }
}
public class DocumentUserSort implements Comparator<DocumentDto> {

    @Override
    public int compare(DocumentDto o1, DocumentDto o2) {
        return o1.getCreateUser().compareTo(o2.getCreateUser());
    }
}
public class DocumentTypeSort implements Comparator<DocumentDto> {

    @Override
    public int compare(DocumentDto o1, DocumentDto o2) {
        return o1.getDocumentType().getCode().compareTo(o2.getDocumentType().getCode());
    }
}

Conclusion : this method isn't has efficient but you can create generic sort using a file configuration in this way.

You have to look how this is called:

someObject.equals(someOtherObj); 

This invokes the equals method on the instance of someObject. Now, inside that method:

public boolean equals(Object obj) {   if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj?     return true;//If so, these are the same objects, and return true   } 

You can see that this is referring to the instance of the object that equals is called on. Note that equals() is non-static, and so must be called only on objects that have been instantiated.

Note that == is only checking to see if there is referential equality; that is, the reference of this and obj are pointing to the same place in memory. Such references are naturally equal:

Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place 

Further note that equals() is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:

FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing. 

you can chain more than 2 conditions too :

if [ \( "$1" = '--usage' \) -o \( "$1" = '' \) -o \( "$1" = '--help' \) ]
then
   printf "\033[2J";printf "\033[0;0H"
   cat << EOF_PRINT_USAGE

   $0 - Purpose: upsert qto http json data to postgres db

   USAGE EXAMPLE:

   $0 -a foo -a bar



EOF_PRINT_USAGE
   exit 1
fi

YES - solution is to save workbook in to XML file (eg. 'XML Spreadsheet 2003') and edit this file as text in notepad! use "SEARCH" function of notepad to find query text and change your data to "?".

save and open in excel, try refresh data and excel will be monit about parameters.

This issue comes when trust verification of app fails.

You can trust app from Settings shown in below images.

If this dosen't work then delete app and re-install it.

Using this instead of $scope works.

function AppCtrl($scope){_x000D_
  $scope.searchText = "";_x000D_
  $scope.check = function () {_x000D_
    console.log("You typed '" + this.searchText + "'"); // used 'this' instead of $scope_x000D_
  }_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app>_x000D_
  <div ng-controller="AppCtrl">_x000D_
    <input ng-model="searchText"/>_x000D_
    <button ng-click="check()">Write console log</button>_x000D_
  </div>_x000D_
</div>

Edit: At the time writing this answer, I had much more complicated situation than this. After the comments, I tried to reproduce it to understand why it works, but no luck. I think somehow (don't really know why) a new child scope is generated and this refers to that scope. But if $scope is used, it actually refers to the parent $scope because of javascript's lexical scope feature.

Would be great if someone having this problem tests this way and inform us.

You can try using jQuery with the Attribute Contains Prefix Selector.

$('[id|=q1_]')

Haven't tested it though.

Though I haven't personally tested, I have good reason to believe that the above stated AT COMMAND solution will work for XP, 2000 and Server 2003. Per my and Bryant's testing, we've identified that the same approach does not work with Vista or Windows Server 2008 -- most probably due to added security and the /interactive switch being deprecated.

However, I came across this article which demonstrates the use of PSTools from SysInternals (which was acquired by Microsoft in July, 2006.) I launched the command line via the following and suddenly I was running under the Local Admin Account like magic:

psexec -i -s cmd.exe

PSTools works well. It's a lightweight, well-documented set of tools which provides an appropriate solution to my problem.

Many thanks to those who offered help.

If you are interested in portability between different SQL servers you should use ANSI SQL queries. String escaping in ANSI SQL is done by using double quotes ("). Unfortunately, this escaping method is not portable to MySQL, unless it is set in ANSI compatibility mode.

Personally, I always start my MySQL server with the --sql-mode='ANSI' argument since this allows for both methods for escaping. If you are writing queries that are going to be executed in a MySQL server that was not setup / is controlled by you, here is what you can do:

• Write all you SQL queries in ANSI SQL

• Enclose them in the following MySQL specific queries:

  SET @OLD_SQL_MODE=@@SQL_MODE;
  SET SESSION SQL_MODE='ANSI';
  -- ANSI SQL queries
  SET SESSION SQL_MODE=@OLD_SQL_MODE;
  

This way the only MySQL specific queries are at the beginning and the end of your .sql script. If you what to ship them for a different server just remove these 3 queries and you're all set. Even more conveniently you could create a script named: script_mysql.sql that would contain the above mode setting queries, source a script_ansi.sql script and reset the mode.

I had the same issue and I have tried many answers but nothing worked.

I tried the following and it worked successfully :

<input type=text  data-date-format='yy-mm-dd'  > 

Well I know this answer is not an experienced programmer's approach and of an Old It consultant , but it worked for me .

the answer is "TRY TURNING IT ON AND OFF" . restart codeblocks and it works well reminds me of the 2006 comedy show It Crowd .

Search your installation of PhpMyAdmin for a file called Documentation.txt. This describes how to create a file called config.inc.php and how you can configure the username and password.

I currently also have that requirement of waiting for some services to be up and running before others start. Also read the suggestions here and on some other places. But most of them require that the docker-compose.yml some how has to be changed a bit. So I started working on a solution which I consider to be an orchestration layer around docker-compose itself and I finally came up with a shell script which I called docker-compose-profile. It can wait for tcp connection to a certain container even if the service does not expose any port to the host directy. The trick I am using is to start another docker container inside the stack and from there I can (usually) connect to every service (as long no other network configuration is applied). There is also waiting method to watch out for a certain log message. Services can be grouped together to be started in a single step before another step will be triggered to start. You can also exclude some services without listing all other services to start (like a collection of available services minus some excluded services). This kind of configuration can be bundled to a profile. There is a yaml configuration file called dcp.yml which (for now) has to be placed aside your docker-compose.yml file.

For your question this would look like:

command:
  aliases:
    upd:
      command: "up -d"
      description: |
        Create and start container. Detach afterword.

profiles:
  default:
    description: |
      Wait for rabbitmq before starting worker.
    command: upd
    steps:
      - label: only-rabbitmq
        only: [ rabbitmq ]
        wait:
          - 5@tcp://rabbitmq:5432
      - label: all-others

You could now start your stack by invoking

dcp -p default upd

or even simply by

dcp

as there is only a default profile to run up -d on.

There is a tiny problem. My current version does not (yet) support special waiting condition like the ony You actually need. So there is no test to send a message to rabbit.

I have been already thinking about a further waiting method to run a certain command on host or as a docker container. Than we could extend that tool by something like

...
        wait:
          - service: rabbitmq
            method: container
            timeout: 5
            image: python-test-rabbit
...

having a docker image called python-test-rabbit that does your check.

The benefit then would be that there is no need anymore to bring the waiting part to your worker. It would be isolated and stay inside the orchestration layer.

May be someone finds this helpful to use. Any suggestions are very welcome.

You can find this tool at https://gitlab.com/michapoe/docker-compose-profile

My simple solution. IMHO it's the cleanest.

First create a application.yml

spring.main.allow-bean-definition-overriding: true

security:
  oauth2:
    client:
      clientId: XXX
      clientSecret: XXX
      accessTokenUri: XXX
      tokenName: access_token
      grant-type: client_credentials

Create the main class: Main

@SpringBootApplication
@EnableOAuth2Client
public class Main extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/").permitAll();
    }

    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }

    @Bean
    public OAuth2RestTemplate oauth2RestTemplate(ClientCredentialsResourceDetails details) {
        return new OAuth2RestTemplate(details);
    }

}

Then Create the controller class: Controller

@RestController
class OfferController {

    @Autowired
    private OAuth2RestOperations restOperations;

    @RequestMapping(value = "/<your url>"
            , method = RequestMethod.GET
            , produces = "application/json")
    public String foo() {
        ResponseEntity<String> responseEntity = restOperations.getForEntity(<the url you want to call on the server>, String.class);
        return responseEntity.getBody();
    }
}

I was facing the same problem on Linux, what I did was to select all the content (ctrl-A) and then press ctrl+shift+L, It gives you a cursor on each line and then you can add similar content to each column.

Also you can perform other operations like cut, copy and paste column wise.

PS :- If you want to select a rectangular set of data from text, you can also press shift and hold Right Mouse button and then select data in a rectangular fashion. Then press CTRL+SHIFT+L to get the cursor on each line.

//Do this

int IS_NULL_PTR(char *k){
memset(&k, k, sizeof k);
if(k) { return 71; } ;
return 72;
}
int PRINT_PTR_SAFE(char *KR){
    char *E=KR;;

I think static and volatile have no relation at all. I suggest you read java tutorial to understand Atomic Access, and why use atomic access, understand what is interleaved, you will find answer.

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

An angular solution using $anchorScroll taken from a now archived blog post by Ben Lesh, which is also reproduced in some detail at this SO answer he contributed (including a rewrite of how to do this within a routing):

app.controller('MainCtrl', function($scope, $location, $anchorScroll) {
  var i = 1;
  
  $scope.items = [{ id: 1, name: 'Item 1' }];
  
  $scope.addItem = function (){
    i++;
    //add the item.
    $scope.items.push({ id: i, name: 'Item ' + i});
    //now scroll to it.
    $location.hash('item' + i);
    $anchorScroll();
  };
});

And here is the plunker, from the blog that provided this solution: http://plnkr.co/edit/xi2r8wP6ZhQpmJrBj1jM?p=preview

Important to note that the template at that plunker includes this, which sets up the id that you're using $anchorScroll to scroll to:

<li ng-repeat="item in items" 
    id="item{{item.id}}"
>{{item.name}</li>

And if you care for a pure javascript solution, here is one:

Invoke runScroll in your code with parent container id and target scroll id:

function runScroll(parentDivId,targetID) {
    var longdiv;
    longdiv = document.querySelector("#" + parentDivId);
    var div3pos = document.getElementById(targetID).offsetTop;
    scrollTo(longdiv, div3pos, 600);
}


function scrollTo(element, to, duration) {
    if (duration < 0) return;
    var difference = to - element.scrollTop;
    var perTick = difference / duration * 10;

    setTimeout(function () {
        element.scrollTop = element.scrollTop + perTick;
        if (element.scrollTop == to) return;
        scrollTo(element, to, duration - 10);
    }, 10);
}

Both other answers are correct, but I thought it worth noting that the place where I got stuck was not realizing that you'll need order by the alias and make sure that the alias is the same for both the selects... so

select 'foo'
union
select item as `foo`
from myTable
order by `foo`

notice that I'm using single quotes in the first select but backticks for the others.

That will get you the sorting you need.

Please click on this link it should work ..

http://www.php-guru.in/2013/html-to-pdf-conversion-in-codeigniter/

Or you can see below

There are number of PHP libraries on the web to convert HTML page to PDF file. They are easy to implement and deploy when you are working on any web application in core PHP. But when we try to integrate this libraries with any framework or template, then it becomes very tedious work if the framework which we are using does not have its own library to integrate it with any PDF library. The same situation came in front of me when there was one requirement to convert HTML page to PDF file and the framework I was using was codeigniter.

I searched on web and got number of PHP libraries to convert HTML page to PDF file. After lot of research and googling I decided to go with TCPDF PHP library to convert HTML page to PDF file for my requirement. I found TCPDf PHP library quite easy to integrate with codeigniter and stated working on it. After successfully completing my integration of codeigniter and TCPDF, I thought of sharing this script on web.

Now, let’s start with implimentation of the code.

Download the TCPDF library code, you can download it from TCPDF website http://www.tcpdf.org/.

Now create “tcpdf” folder in “application/helpers/” directory of your web application which is developed in codeigniter. Copy all TCPDF library files and paste it in “application/helpers/tcpdf/” directory. Update the configuration file “tcpdf_config.php” of TCPDF, which is located in “application/helpers/tcpdf/config” directory, do changes according to your applicatoin requirements. We can set logo, font, font size, with, height, header etc in the cofing file. Give read, write permissions to “cache” folder which is there in tcpdf folder. After defining your directory structure, updating configuration file and assigning permissions, here starts your actual coding part.

Create one PHP helper file in “application/helpers/” directory of codeigniter, say “pdf_helper.php”, then copy below given code and paste it in helper file

Helper: application/helpers/pdf_helper.php

function tcpdf()
{
    require_once('tcpdf/config/lang/eng.php');
    require_once('tcpdf/tcpdf.php');
}

Then in controller file call the above helper, suppose our controller file is “createpdf.php” and it has method as pdf(), so the method pdf() will load the “pdf_helper” helper and will also have any other code.

Controller: application/controllers/createpdf.php

function pdf()
{
    $this->load->helper('pdf_helper');
    /*
        ---- ---- ---- ----
        your code here
        ---- ---- ---- ----
    */
    $this->load->view('pdfreport', $data);
}

Now create one view file, say “pdfreport.php” in “application/views/” directory, which is also loaded in pdf() method in controller. So in view file we can directly call the tcpdf() function which we have defined in “pdf_helper” helper, which will load all required TCPDF classes, functions, variable etc. Then we can directly use the TCPDF example codes as it is in our current controller or view. Now in out current view “pdfreport” copy the given code below:

View: application/views/pdfreport.php

tcpdf();
$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = "PDF Report";
$obj_pdf->SetTitle($title);
$obj_pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $title, PDF_HEADER_STRING);
$obj_pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$obj_pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$obj_pdf->SetDefaultMonospacedFont('helvetica');
$obj_pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$obj_pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$obj_pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$obj_pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$obj_pdf->SetFont('helvetica', '', 9);
$obj_pdf->setFontSubsetting(false);
$obj_pdf->AddPage();
ob_start();
    // we can have any view part here like HTML, PHP etc
    $content = ob_get_contents();
ob_end_clean();
$obj_pdf->writeHTML($content, true, false, true, false, '');
$obj_pdf->Output('output.pdf', 'I');

Thus our HTML page will be converted to PDF using TCPDF in CodeIgniter. We can also embed images,css,modifications in PDF file by using TCPDF library.

Inside try block we write codes that can throw an exception. The catch block is where we handle the exception. The finally block is always executed no matter whether exception occurs or not.

Now if we have try-finally block instead of try-catch-finally block then the exception will not be handled and after the try block instead of control going to catch block it will go to finally block. We can use try-finally block when we want to do nothing with the exception.

The one the eclipse run in is the default java installed in the system (unless set specifically in the eclipse.ini file, use the -vm option). You can of course add more Java runtimes and use them for your projects

The string you've written is the right one, but it is specific to your environment. If you want to know the exact update then run the following code:

public class JavaVersion {
  public static void main(String[] args) {
    System.out.println(System.getProperty("java.runtime.version"));
  }
}

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

Font's don't have a color; only when using the font you can set the color of the component. For example, when using a JTextArea:

JTextArea txt = new JTextArea();
Font font = new Font("Verdana", Font.BOLD, 12);
txt.setFont(font);
txt.setForeground(Color.BLUE);

According to this link, the createFont() method creates a new Font object with a point size of 1 and style PLAIN. So, if you want to increase the size of the Font, you need to do this:

 Font font = Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"));
 return font.deriveFont(12f);

For anyone with this situation: I saw this error when I accidentally used my_first_scope::my_second_scope::true in place of simply true, like this:

bool my_var = my_first_scope::my_second_scope::true;

instead of:

bool my_var = true;

This is because I had a macro which caused MY_MACRO(true) to expand into my_first_scope::my_second_scope::true, by mistake, and I was actually calling bool my_var = MY_MACRO(true);.

Here's a quick demo of this type of scoping error:

Program (you can run it online here: https://onlinegdb.com/BkhFBoqUw):

#include <iostream>
#include <cstdio>

namespace my_first_scope 
{
namespace my_second_scope
{
} // namespace my_second_scope
} // namespace my_first_scope

int main()
{
    printf("Hello World\n");
    
    bool my_var = my_first_scope::my_second_scope::true;
    
    std::cout << my_var << std::endl;

    return 0;
}

Output (build error):

main.cpp: In function ‘int main()’:
main.cpp:27:52: error: expected unqualified-id before ‘true’
     bool my_var = my_first_scope::my_second_scope::true;
                                                    ^~~~

Notice the error: error: expected unqualified-id before ‘true’, and where the arrow under the error is pointing. Apparently the "unqualified-id" in my case is the double colon (::) scope operator I have just before true.

When I add in the macro and use it (run this new code here: https://onlinegdb.com/H1eevs58D):

#define MY_MACRO(input) my_first_scope::my_second_scope::input

...

bool my_var = MY_MACRO(true);

I get this new error instead:

main.cpp: In function ‘int main()’:
main.cpp:29:28: error: expected unqualified-id before ‘true’
     bool my_var = MY_MACRO(true);
                            ^
main.cpp:16:58: note: in definition of macro ‘MY_MACRO’
 #define MY_MACRO(input) my_first_scope::my_second_scope::input
                                                          ^~~~~

Note that apart from rows and columns there is a number of channels and type. When it is clear what type is, the channels can act as an extra dimension as in CV_8UC3 so you would address a matrix as

uchar a = M.at<Vec3b>(y, x)[i];

So the size in terms of elements of elementary type is M.rows * M.cols * M.cn

To find the max element one can use

Mat src;
double minVal, maxVal;
minMaxLoc(src, &minVal, &maxVal);

You can try color-sampler. It's an easy way to pick color in a canvas. See demo.

Try this:

new ClassPathXmlApplicationContext("file:src/main/resources/beans.xml");

file: preffix point to file system resources, not classpath.

file path can be relative or system (/home/user/Work/src...)

After doing much R&D on this issue I got the Solution,

In my case I am using Service that will run every 2 second and with the runonUIThread, I was wondering the problem was there but not at all. The next issue that I found is that I am using large Image in may App and thats the problem.

I removed the Images and set new Images.

Conclusion :- Look into your code is there any raw file that you are using is of big size.

A simple answer is to add checked attributes within a checkbox:

$('input[id='+$(this).attr("id")+']').attr("checked", "checked");

If you are using Java 8 you can encode the byte[] by doing

MessageDigest digest = MessageDigest.getInstance("SHA-256");
byte[] hash = digest.digest(text.getBytes(StandardCharsets.UTF_8));
String encoded = Base64.getEncoder().encodeToString(hash);

When dealing with the HTML DOM (ie. this), the array selector [0] must be used to retrieve the jQuery element from the Javascript array.

$(this)[0].getAttribute('src');

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

If you take clue from Hibernate:

Hibernate reads/writes Object's state with its field. Hibernate also maps the Java Bean style properties to DB Schema. Hibernate Access the fields for loading/saving the object. If the mapping is done by property, hibernate uses the getter and setter.

It is the Encapsulation that differentiates means where you have getter/setters for a field and it is called property, withthat and we hide the underlying data structure of that property within setMethod, we can prevent unwanted change inside setters. All what encapsulation stands for...

Fields must be declared and initialized before they are used. Mostly for class internal use.

Properties can be changed by setter and they are exposed by getters. Here field price has getter/setters so it is property.

class Car{
 private double price;
 public double getPrice() {…};
 private void setPrice(double newPrice) {…};
}

<class name="Car" …>
<property name="price" column="PRICE"/>
</class>

Similarly using fields, [In hibernate it is the recommended way to MAP using fields, where private int id; is annotated @Id, but with Property you have more control]

class Car{
  private double price;
}
<class name="Car">
<property name=" price" column="PRICE" access="field"/>
</class>

Java doc says: Field is a data member of a class. A field is non static, non-transient instance variable. Field is generally a private variable on an instance class.

I realize this is late, but there is another way to obtain the URL of the profile image.

To your original url, you can add the parameter redirect=false to obtain the actual URL of the image you'd normally be redirected to.

So, the new request would look like http://graph.facebook.com/517267866/picture?type=large&redirect=false. This will return a JSON object containing the URL of the picture and a boolean is_silhouette (true if the picture is the default Facebook picture).

The picture will be of the size you specified, as well. You can test this additionally by adding dimensions: http://graph.facebook.com/517267866/picture?type=large&redirect=false&width=400&height=400

Configure your webserver to send caching control HTTP headers for the script.

Fake headers in the HTML documents:

1. Aren't as well supported as real HTTP headers
2. Apply to the HTML document, not to resources that it links to

The pertinent section reads:

There's no setting to fetch all records. You wouldn't like SQL Developer to fetch for minutes on big tables anyway. If, for 1 specific table, you want to fetch all records, you can do Control-End in the results pane to go to the last record. You could time the fetching time yourself, but that will vary on the network speed and congestion, the program (SQL*Plus will be quicker than SQL Dev because it's more simple), etc.

There is also a button on the toolbar which is a "Fetch All" button.

FWIW Be careful retrieving all records, for a very large recordset it could cause you to have all sorts of memory issues etc.

As far as I know, SQL Developer uses JDBC behind the scenes to fetch the records and the limit is set by the JDBC setMaxRows() procedure, if you could alter this (it would prob be unsupported) then you might be able to change the SQL Developer behaviour.

It depends whether you are talking about data, or the code contained within a spreadsheet. While I have a strong dislike of Microsoft's Visual Sourcesafe and normally would not recommended it, it does integrate easily with both Access and Excel, and provides source control of modules.

[In fact the integration with Access, includes queries, reports and modules as individual objects that can be versioned]

The MSDN link is here.

I prefer this. This is not the best way, but a fast solution.

//Building the table includes:
StringBuilder query= new StringBuilder();
query.append("CREATE TABLE "+TABLE_NAME+ " (");
query.append(COLUMN_ID+"int primary key autoincrement,");
query.append(COLUMN_CREATION_DATE+" DATE)");

//Inserting the data includes this:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
values.put(COLUMN_CREATION_DATE,dateFormat.format(reactionGame.getCreationDate())); 

// Fetching the data includes this:
try {
   java.util.Date creationDate = dateFormat.parse(cursor.getString(0);
   YourObject.setCreationDate(creationDate));
} catch (Exception e) {
   YourObject.setCreationDate(null);
}

Well it's been almost 9 years since I originally posted this and to be honest, Java has made a couple improvements since then. I'll leave my original answer below, but there's no need for people to do what is in it. 9 years ago, during code review I would have questioned why they did it and maybe approved it, maybe not. With modern lambdas available, it's irresponsible to have such a highly voted answer recommending an antiquated approach (that, in all fairness, was dubious to begin with...) In modern Java, that code review would be immediately rejected, and this would be suggested:

void foo(final String str) {
    Thread t = new Thread(() -> someFunc(str));
    t.start();
}

As before, details like handling that thread in a meaningful way is left as an exercise to the reader. But to put it bluntly, if you're afraid of using lambdas, you should be even more afraid of multi-threaded systems.

Original answer, just because:

You can declare a class right in the method

void Foo(String str) {
    class OneShotTask implements Runnable {
        String str;
        OneShotTask(String s) { str = s; }
        public void run() {
            someFunc(str);
        }
    }
    Thread t = new Thread(new OneShotTask(str));
    t.start();
}

As you can't import a .txt file, I would suggest to read words this way.

list_ = open("world.txt").read().split()

The installation of CuDNN is just copying some files. Hence to check if CuDNN is installed (and which version you have), you only need to check those files.

Install CuDNN

Step 1: Register an nvidia developer account and download cudnn here (about 80 MB). You might need nvcc --version to get your cuda version.

Step 2: Check where your cuda installation is. For most people, it will be /usr/local/cuda/. You can check it with which nvcc.

Step 3: Copy the files:

$ cd folder/extracted/contents
$ sudo cp include/cudnn.h /usr/local/cuda/include
$ sudo cp lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

Check version

You might have to adjust the path. See step 2 of the installation.

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

Notes

When you get an error like

F tensorflow/stream_executor/cuda/cuda_dnn.cc:427] could not set cudnn filter descriptor: CUDNN_STATUS_BAD_PARAM

with TensorFlow, you might consider using CuDNN v4 instead of v5.

Simply define vertical-align property for the icon element:

div .icon {
   vertical-align: middle;
}

I think all you need to display the data on an HTML page is JSON.stringify.

For example, if your JSON is stored like this:

var jsonVar = {
        text: "example",
        number: 1
    };

Then you need only do this to convert it to a string:

var jsonStr = JSON.stringify(jsonVar);

And then you can insert into your HTML directly, for example:

document.body.innerHTML = jsonStr;

Of course you will probably want to replace body with some other element via getElementById.

As for the CSS part of your question, you could use RegExp to manipulate the stringified object before you put it into the DOM. For example, this code (also on JSFiddle for demonstration purposes) should take care of indenting of curly braces.

var jsonVar = {
        text: "example",
        number: 1,
        obj: {
            "more text": "another example"
        },
        obj2: {
             "yet more text": "yet another example"
        }
    }, // THE RAW OBJECT
    jsonStr = JSON.stringify(jsonVar),  // THE OBJECT STRINGIFIED
    regeStr = '', // A EMPTY STRING TO EVENTUALLY HOLD THE FORMATTED STRINGIFIED OBJECT
    f = {
            brace: 0
        }; // AN OBJECT FOR TRACKING INCREMENTS/DECREMENTS,
           // IN PARTICULAR CURLY BRACES (OTHER PROPERTIES COULD BE ADDED)

regeStr = jsonStr.replace(/({|}[,]*|[^{}:]+:[^{}:,]*[,{]*)/g, function (m, p1) {
var rtnFn = function() {
        return '<div style="text-indent: ' + (f['brace'] * 20) + 'px;">' + p1 + '</div>';
    },
    rtnStr = 0;
    if (p1.lastIndexOf('{') === (p1.length - 1)) {
        rtnStr = rtnFn();
        f['brace'] += 1;
    } else if (p1.indexOf('}') === 0) {
         f['brace'] -= 1;
        rtnStr = rtnFn();
    } else {
        rtnStr = rtnFn();
    }
    return rtnStr;
});

document.body.innerHTML += regeStr; // appends the result to the body of the HTML document

This code simply looks for sections of the object within the string and separates them into divs (though you could change the HTML part of that). Every time it encounters a curly brace, however, it increments or decrements the indentation depending on whether it's an opening brace or a closing (behaviour similar to the space argument of 'JSON.stringify'). But you could this as a basis for different types of formatting.

Check whether title has any value or not. If not, then retrive the value using Id.

<form>
Title : <input type="text" id="title" size="40" name="title" value = ''/>
<input type="button" onclick="headingSearch(this.form)" value="Submit"/><br /><br />
</form>
<script type="text/javascript">
function headingSearch(f)
{
    var title=jQuery('#title').val();
    $.ajax({
      type: "POST",
      url: "edit.php",
      data: {title:title} ,
      success: function(data) {
    $('.center').html(data); 
}
});
}
</script>

Try this code.

In php code, use echo instead of return. Only then, javascript data will have its value.

Had to face the same issue. The reason is same as the @merv. Issue was with a calendar component added to the page.The component itself add the modal feature to be used in the calendar popup.

So the reasons to break model popup will be one or more of the following

• Loading more than one bootstrap js versions/files (minified ...)
• Adding an external calendar to the page where bootstrap is used
• Adding custom alert or popup library to the page
• Any other library which adds popup behavior

There is also this free API that you can use to make free barcodes in java.

It's not working because console.log() it's not in a "executable area" of the class "App".

A class is a structure composed by attributes and methods.

The only way to have your code executed is to place it inside a method that is going to be executed. For instance: constructor()

console.log('It works here')_x000D_
_x000D_
@Component({..)_x000D_
export class App {_x000D_
 s: string = "Hello2";_x000D_
            _x000D_
  constructor() {_x000D_
    console.log(this.s)            _x000D_
  }            _x000D_
}

Think of class like a plain javascript object.

Would it make sense to expect this to work?

class:  {_x000D_
  s: string,_x000D_
  console.log(s)_x000D_
 }

If you still unsure, try the typescript playground where you can see your typescript code generated into plain javascript.

https://www.typescriptlang.org/play/index.html

It works more or less like this (example using an image/jpg file):

async public Task<HttpResponseMessage> UploadImage(string url, byte[] ImageData)
{
    var requestContent = new MultipartFormDataContent(); 
    //    here you can specify boundary if you need---^
    var imageContent = new ByteArrayContent(ImageData);
    imageContent.Headers.ContentType = 
        MediaTypeHeaderValue.Parse("image/jpeg");

    requestContent.Add(imageContent, "image", "image.jpg");

    return await client.PostAsync(url, requestContent);
}

(You can requestContent.Add() whatever you want, take a look at the HttpContent descendant to see available types to pass in)

When completed, you'll find the response content inside HttpResponseMessage.Content that you can consume with HttpContent.ReadAs*Async.

I wanted to encrypt and decrypt the string as a readable string.

Here is a very simple quick example in C# Visual Studio 2019 WinForms based on the answer from @Pradip.

Right click project > properties > settings > Create a username and password setting.

Now you can leverage those settings you just created. Here I save the username and password but only encrypt the password in it's respectable value field in the user.config file.

Example of the encrypted string in the user.config file.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <userSettings>
        <secure_password_store.Properties.Settings>
            <setting name="username" serializeAs="String">
                <value>admin</value>
            </setting>
            <setting name="password" serializeAs="String">
                <value>AQAAANCMnd8BFdERjHoAwE/Cl+sBAAAAQpgaPYIUq064U3o6xXkQOQAAAAACAAAAAAAQZgAAAAEAACAAAABlQQ8OcONYBr9qUhH7NeKF8bZB6uCJa5uKhk97NdH93AAAAAAOgAAAAAIAACAAAAC7yQicDYV5DiNp0fHXVEDZ7IhOXOrsRUbcY0ziYYTlKSAAAACVDQ+ICHWooDDaUywJeUOV9sRg5c8q6/vizdq8WtPVbkAAAADciZskoSw3g6N9EpX/8FOv+FeExZFxsm03i8vYdDHUVmJvX33K03rqiYF2qzpYCaldQnRxFH9wH2ZEHeSRPeiG</value>

None of above works for godaddy server centOS 6, apache 2.4, php 5.6

Instead, you should

Install the mbstring PHP Extension with EasyApache

check if you already have it by, putty or ssh

php -m | grep mbstring

[if nothing, means missing mbstring]

Now you need to goto godaddy your account page,

click manager server,

open whm ----- search for apache,

open "easy apache 4"(my case)

Now you need customize currently installed packages,

by

click "customize" button on top line next to "currently installed package..."

search mbstring,

click on/off toggle next to it.

click next, next, .... privision..done.

Now you should have mbstring

by check again at putty(ssh)

php -m | grep mbstring [should see mbstring]

or you can find mbstring at phpinfo() page

One classic difference between Synchronized block and Synchronized method is that Synchronized method locks the entire object. Synchronized block just locks the code within the block.

Synchronized method: Basically these 2 sync methods disable multithreading. So one thread completes the method1() and the another thread waits for the Thread1 completion.

class SyncExerciseWithSyncMethod {

public synchronized void method1() {
    try {
        System.out.println("In Method 1");
        Thread.sleep(5000);
    } catch (Exception e) {
        System.out.println("Catch of method 1");
    } finally {
        System.out.println("Finally of method 1");
    }

}

public synchronized void method2() {
    try {
        for (int i = 1; i < 10; i++) {
            System.out.println("Method 2 " + i);
            Thread.sleep(1000);
        }
    } catch (Exception e) {
        System.out.println("Catch of method 2");
    } finally {
        System.out.println("Finally of method 2");
    }
}

}

Output

Synchronized block: Enables multiple threads to access the same object at same time [Enables multi-threading].

class SyncExerciseWithSyncBlock {

public Object lock1 = new Object();
public Object lock2 = new Object();

public void method1() {
    synchronized (lock1) {
        try {
            System.out.println("In Method 1");
            Thread.sleep(5000);
        } catch (Exception e) {
            System.out.println("Catch of method 1");
        } finally {
            System.out.println("Finally of method 1");
        }
    }

}

public void method2() {

    synchronized (lock2) {
        try {
            for (int i = 1; i < 10; i++) {
                System.out.println("Method 2 " + i);
                Thread.sleep(1000);
            }
        } catch (Exception e) {
            System.out.println("Catch of method 2");
        } finally {
            System.out.println("Finally of method 2");
        }
    }
}

}

I realise that this article may be outdated but still I would like to ask smithsv to correct his source code, it contains many mistakes, I managed to correct most of them but still don't know what kind of object x509 could be.Here is the source code as I think is should be:

You could google on "tuple unpacking". This can be used in various places in Python. The simplest is in assignment

>>> x = (1,2)
>>> a, b = x
>>> a
1
>>> b
2

In a for loop it works similarly. If each element of the iterable is a tuple, then you can specify two variables and each element in the loop will be unpacked to the two.

>>> x = [(1,2), (3,4), (5,6)]
>>> for item in x:
...     print "A tuple", item
A tuple (1, 2)
A tuple (3, 4)
A tuple (5, 6)
>>> for a, b in x:
...     print "First", a, "then", b
First 1 then 2
First 3 then 4
First 5 then 6

The enumerate function creates an iterable of tuples, so it can be used this way.

Judging by the desktop folder location you are using Windows. The command in Windows would be:

adb pull /sdcard/log.txt %USERPROFILE%\Desktop\

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

Starting in version 0.7.9 you can use the filter operator .isnot instead of comparing constraints, like this:

query.filter(User.name.isnot(None))

This method is only necessary if pep8 is a concern.

Actually, both INSTALLPATH/TARGETDIR are correct. It depends on how MSI processes this.

I create a MSG using wixToolSet. In WXS file, there is "Directory" Node, which root dir maybe like the following:

<Directory Id="**TARGETDIR**" Name="SourceDir">;

As you can see: Id is which you should use.

If you have to choose between __repr__ or __str__ go for the first one, as by default implementation __str__ calls __repr__ when it wasn't defined.

Custom Vector3 example:

class Vector3(object):
    def __init__(self, args):
        self.x = args[0]
        self.y = args[1]
        self.z = args[2]

    def __repr__(self):
        return "Vector3([{0},{1},{2}])".format(self.x, self.y, self.z)

    def __str__(self):
        return "x: {0}, y: {1}, z: {2}".format(self.x, self.y, self.z)

In this example, repr returns again a string that can be directly consumed/executed, whereas str is more useful as a debug output.

v = Vector3([1,2,3])
print repr(v)    #Vector3([1,2,3])
print str(v)     #x:1, y:2, z:3

Use the below code in android.support.v4

FragmentTransaction ft1 = getFragmentManager().beginTransaction();
WebViewFragment w1 = new WebViewFragment();
w1.init(linkData.getLink());
ft1.addToBackStack(linkData.getName());
ft1.replace(R.id.listFragment, w1);
ft1.commit();

The problem with the above approaches, is that you have to repeat the several cases every time you call the function which has the switch. A more robust solution is to have a map or a dictionary.

Here is an example:

// The Map, divided by concepts
var dictionary = {
  timePeriod: {
    'month': [1, 'monthly', 'mensal', 'mês'],
    'twoMonths': [2, 'two months', '2 months', 'bimestral', 'bimestre'],
    'trimester': [3, 'trimesterly', 'quarterly', 'trimestral'],
    'semester': [4, 'semesterly', 'semestral', 'halfyearly'],
    'year': [5, 'yearly', 'annual', 'ano']
  },
  distance: {
    'km': [1, 'kms', 'kilometre', 'kilometers', 'kilometres'],
    'mile': [2, 'mi', 'miles'],
    'nordicMile': [3, 'Nordic mile', 'mil (10 km)', 'Scandinavian mile']
  },
  fuelAmount: {
    'ltr': [1, 'l', 'litre', 'Litre', 'liter', 'Liter'],
    'gal (imp)': [2, 'imp gallon', 'imperial gal', 'gal (UK)'],
    'gal (US)': [3, 'US gallon', 'US gal'],
    'kWh': [4, 'KWH']
  }
};

// This function maps every input to a certain defined value
function mapUnit (concept, value) {
  for (var key in dictionary[concept]) {
    if (key === value ||
      dictionary[concept][key].indexOf(value) !== -1) {
      return key
    }
  }
  throw Error('Uknown "'+value+'" for "'+concept+'"')
}

// You would use it simply like this
mapUnit("fuelAmount", "ltr") // => ltr
mapUnit("fuelAmount", "US gal") // => gal (US)
mapUnit("fuelAmount", 3) // => gal (US)
mapUnit("distance", "kilometre") // => km

// Now you can use the switch statement safely without the need
// to repeat the combinations every time you call the switch
var foo = 'monthly'
switch (mapUnit ('timePeriod', foo)) {
  case 'month':
    console.log('month')
    break
  case 'twoMonths':
    console.log('twoMonths')
    break
  case 'trimester':
    console.log('trimester')
    break
  case 'semester':
    console.log('semester')
    break
  case 'year':
    console.log('year')
    break
  default:
    throw Error('error')
}

Here's another method that's unorthodox, but works*.

I recently found myself in a situation where I'd checked in breaking code, knowing that I couldn't update our production code to it until all the integration work had taken place (in retrospect this was a bad decision, but we didn't expect to get stalled out, but other projects took precedence). That was several months ago, and the integration has been stalled for that entire time. Along comes a requirement to change the base code and get it into production last week without the breaking change.

Here's what we did:

After verifying that the new requirement doesn't break anything when using the revision before my check in, I made a copy of the working directory containing the new code. Then I deleted everything in the working directory and checked out the revision I wanted to it. Then I deleted all the files I'd just checked out, and copied in the files from the working copy. Then I committed that change, effectively wiping out the breaking change from the repository and getting the production code in place as the head revision. We still have the breaking change available, but it's no longer in the head revision so we can move forward to production.

*I don't recommend this method, but if you find yourself in a similar situation, it's a way out that's not too painful.

UPDATE t
SET cumulative_sum = (
 SELECT SUM(x.count)
 FROM t x
 WHERE x.id <= t.id
)

To set transparent you can set opaque of panel to false like

   JPanel panel = new JPanel();
   panel.setOpaque(false);

But to make it transculent use alpha property of color attribute like

   JPanel panel = new JPanel();
   panel.setBackground(new Color(0,0,0,125));

where last parameter of Color is for alpha and alpha value ranges between 0 and 255 where 0 is full transparent and 255 is fully opaque

Use padding to fake it since vertical-align doesn't work on text inputs.

This script helps you to switch over from a Parent window to a Child window and back cntrl to Parent window

String parentWindow = driver.getWindowHandle();
Set<String> handles =  driver.getWindowHandles();
   for(String windowHandle  : handles)
       {
       if(!windowHandle.equals(parentWindow))
          {
          driver.switchTo().window(windowHandle);
         <!--Perform your operation here for new window-->
         driver.close(); //closing child window
         driver.switchTo().window(parentWindow); //cntrl to parent window
          }
       }

Hope this is useful for someone.

I was unable to get the jQuery('#myInputElement').trigger('input') event to be picked up my angular app.

I was however, able to get angular.element(jQuery('#myInputElement')).triggerHandler('input') to be picked up.

make sure you are not running sudo git clone [email protected]:project/somethiing.git, otherwise ssh will look in /root/.ssh instead of the key you uploaded ~/.ssh/id_rsa

In my instance the solution was moving the jQuery include just before the </head> tag. With the Slick include at the bottom before the </body> and just before my script include that initiates the slider.

Er, it's not really a test if you don't add something to your path:

bill@bill-desktop:~$ ls -l /opt/pkg/bin
total 12
-rwxr-xr-x 1 root root   28 2009-01-22 18:58 foo
bill@bill-desktop:~$ which foo
/opt/pkg/bin/foo
bill@bill-desktop:~$ sudo su
root@bill-desktop:/home/bill# which foo
root@bill-desktop:/home/bill# 

Follow this method. Using this way you can simply update the UI from a background thread. runOnUiThread work on the main(UI) thread . I think this code snippet is less complex and easy, especially for beginners.

AsyncTask.execute(new Runnable() {
            @Override
            public void run() {

            //code you want to run on the background
            someCode();

           //the code you want to run on main thread
 MainActivity.this.runOnUiThread(new Runnable() {

                    public void run() {

/*the code you want to run after the background operation otherwise they will executed earlier and give you an error*/
                        executeAfterOperation();

                   }
                });
            }
        });

in the case of a service

create a handler in the oncreate

 handler = new Handler();

then use it like this

 private void runOnUiThread(Runnable runnable) {
        handler.post(runnable);
    }

You can see value inside [object Object] like this

Alert.alert(  JSON.stringify(userDate)  );

Try like this

    realm.write(() => {
       const userFormData = realm.create('User',{
       user_email: value.username,
       user_password: value.password,
      });
     });

      const userDate = realm.objects('User').filtered('user_email == $0', value.username.toString(), );
      Alert.alert(  JSON.stringify(userDate)  );

Hi if you are using react-router v-6.0.0-beta or V6 in This version Redirect Changes to Navigate like this

import { Navigate } from 'react-router-dom'; // like this CORRECT in v6 import { Redirect } from 'react-router-dom'; // like this CORRECT in v5

import { Redirect } from 'react-router-dom'; // like this WRONG in v6 // This will give you error in V6 of react-router and react-router dom

please make sure use both same version in package.json { "react-router": "^6.0.0-beta.0", //Like this "react-router-dom": "^6.0.0-beta.0", // like this }

this above things only works well in react Router Version 6

This is actually possible since Facebook was able to do it. Well, not the actual web developer tools but the execution of Javascript in console.

See this: How does Facebook disable the browser's integrated Developer Tools?

This really wont do much though since there are other ways to bypass this type of client-side security.

When you say it is client-side, it happens outside the control of the server, so there is not much you can do about it. If you are asking why Facebook still does this, this is not really for security but to protect normal users that do not know javascript from running code (that they don't know how to read) into the console. This is common for sites that promise auto-liker service or other Facebook functionality bots after you do what they ask you to do, where in most cases, they give you a snip of javascript to run in console.

If you don't have as much users as Facebook, then I don't think there's any need to do what Facebook is doing.

Even if you disable Javascript in console, running javascript via address bar is still possible.

and if the browser disables javascript at address bar, (When you paste code to the address bar in Google Chrome, it deletes the phrase 'javascript:') pasting javascript into one of the links via inspect element is still possible.

Inspect the anchor:

Paste code in href:

Bottom line is server-side validation and security should be first, then do client-side after.

If you just want to run a function for testing purposes, you can use the Immediate Window in Access.

Press Ctrl + G in the VBA editor to open it.

Then you can run your functions like this:

• ?YourFunction("parameter")
  (for functions with a return value - the return value is displayed in the Immediate Window)
• YourSub "parameter"
  (for subs without a return value, or for functions when you don't care about the return value)
• ?variable
  (to display the value of a variable)

JAD doesn't work for me (Ubuntu 11.10 issue) so I've moved forward and sopped on JODO. At least it has Open Java source code and been able to decompile my .class properly.

I recommend to check out 'branches/generic' branch first. The trunks is not stable.

I faced same problem in emulator, but I solved it like this:

Create new emulator with x86_64 system image(ABI)

select device

select x86_64

That's it.

This error indicates the system(Device) not capable for run the application.

I hope this is helpful to someone.

Eli, it is important to remember that in css specificity goes a long way. If your inline css is using the !important and isn't overriding the imported stylesheet rules then closely observe the code using a tool such as 'firebug' for firefox. It will show you the css being applied to your element. If there is a syntax error firebug will show you in the warning panel that it has thrown out the declaration.

Also remember that in general an id is more specific than a class is more specific than an element.

Hope that helps.

You can use a LENGTH(that_string) minus the number of characters you want to remove in the SUBSTRING() select perhaps or use the TRIM() function.

Not exactly related, but as this is the first post I found in my search for a similar solution I think it's worth posting here.

I was running into permission issues on Windows 10 trying to delete my node_modules folder after a failed attempt at installing electron-redux. It seems electron-redux added @types to my node_modules, which had incorrect permissions set up.

rimraf did not work as it still ran into permission issues.

I ended up renaming node_modules then a simple delete worked.

If the response is in json you could do something like (python3):

import json
import requests as reqs

# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')

# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)

for i in response_dict:
    print("key: ", i, "val: ", response_dict[i])

To see everything in the response you can use .__dict__:

print(response.__dict__)

Try this:

Request request = chain.request();
Buffer buffer = new Buffer();
request.body().writeTo(buffer);
String body = buffer.readUtf8();

After this, in the body there is the JSON you are interested in.

For the string data

 output = []

     def uniq(input):
         if input not in output:
            output.append(input)
 print output     

Help -> check for updates upon Eclipse update solved the issue

even there is no right or wrong answer for this question , but I personally prefer 960px width . since all modern monitors support at least 1024 × 768 pixel resolution. 960 is divisible by 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320 and 480. This makes it a highly flexible base number to work with.

as a workaround you can use the stdin device in /dev directory

....| for item in `cat /dev/stdin` ; do echo $item ;done

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

Finally I found the solution, that works for me:

jQuery.ajax ({
    url: myurl,
    type: "POST",
    data: JSON.stringify({data:"test"}),
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function(){
        //
    }
});

If you just want a unique-ish number, then

var timestamp = new Date().getUTCMilliseconds();

would get you a simple number. But if you need the readable version, you're in for a bit of processing:

var now = new Date();

timestamp = now.getFullYear().toString(); // 2011
timestamp += (now.getMonth < 9 ? '0' : '') + now.getMonth().toString(); // JS months are 0-based, so +1 and pad with 0's
timestamp += ((now.getDate < 10) ? '0' : '') + now.getDate().toString(); // pad with a 0
... etc... with .getHours(), getMinutes(), getSeconds(), getMilliseconds()

If you are pulling from git from local to server, you will need to clear cache sometimes because of the view files it gets uploaded with it / or other cached files .

php artisan cache:clear

Sometimes it might just to the trick if your application was working before the git pull

JsonArray jsonArray;
Iterator<JsonElement> it = jsonArray.iterator();
while(it.hasNext()){
    System.out.println(it.next());
}

Here's a way to do it: make your "topmost" window subscribe to your other windows GotFocus and LostFocus events and use the following as the event handlers:

class TopMostWindow
{
    void OtherWindow_LostFocus(object sender, EventArgs e)
    {
        this.Topmost = false;
    }

    void OtherWindow_GotFocus(object sender, EventArgs e)
    {
        this.Topmost = true;
    }
}

This is how I did it. In config.php

$config['HTML_TITLE'] = "SO TITLE test";

In applications/view/header.php (assuming html code)

<title><?=$this->config->item("HTML_TITLE");?> </title>

Of course you can use floats or doubles for "critical" things ... Many applications do nothing but crunch numbers using these datatypes.

You might have misunderstood some of the various caveats regarding floating-point numbers, such as the recommendation to never compare for exact equality, and so on.

Just my two sends here

I was facing this issue with datetimes so what I did is this:

const moment = require('moment-timezone')

const date = moment.tz('America/Bogota').format()

Then save date to db to be able to compare it from some query.

To install moment-timezone

npm i moment-timezone

OK, there are few ways to do that, but let's start with the simplest one and latest approach to do this, this function is called find().

Just be careful when you using find to as even IE11 dosn't support it, so it needs to be transpiled...

so you have this object as you said:

var jsObjects = [
   {a: 1, b: 2}, 
   {a: 3, b: 4}, 
   {a: 5, b: 6}, 
   {a: 7, b: 8}
];

and you can write a function and get it like this:

function filterValue(obj, key, value) {
  return obj.find(function(v){ return v[key] === value});
}

and use the function like this:

filterValue(jsObjects, "b", 6); //{a: 5, b: 6}

Also in ES6 for even shortened version:

const filterValue = (obj, key, value)=> obj.find(v => v[key] === value);

This method only return the first value which match..., for better result and browser support, you can use filter:

const filterValue = (obj, key, value)=> obj.filter(v => v[key] === value);

and we will return [{a: 5, b: 6}]...

This method will return an array instead...

You simpley use for loop as well, create a function like this:

function filteredArray(arr, key, value) {
  const newArray = [];
  for(i=0, l=arr.length; i<l; i++) {
    if(arr[i][key] === value) {
      newArray.push(arr[i]);
    }
  }
 return newArray;
}

and call it like this:

filteredArray(jsObjects, "b", 6); //[{a: 5, b: 6}]

i have solve this problem several times using the same steps :

1- Close Eclipse.

2- Restart your phone.

3- End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.

4- Issue kill and start command in \platform-tools\

C:\sdk\platform-tools>adb kill-server

C:\sdk\platform-tools>adb start-server

5- If it says something like 'started successfully', you are good.

but now it's doesn't work cause i have an anti-virus called "Baidu", this program have run "Baidu ADB server", finally i turn this process off and retry above steps it's work properly.

Adding to @zzzzzzz answer, I ran the command:python3 -c "import sys; print(sys.path)" and it provided me with different paths comparing to the same command with python. The paths that were displayed with python3 were "python3 oriented".

See the output of the two different commands:

python -c "import sys; print(sys.path)"

['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages/setuptools-39.1.0-py2.7.egg', '/usr/lib/python2.7/dist-packages']

python3 -c "import sys; print(sys.path)"

['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

Both commands were executed on my Ubuntu 18.04 machine.

A DBMS is used for storage of data in files. In DBMS relationships can be established between two files. Data is stored in flat files with metadata whereas RDBMS stores the data in tabular form with additional condition of data that enforces relationships among the tables. Unlike RDBMS, DBMS does not support client server architecture. RDBMS imposes integrity constraints and also follows normalization which is not supported in DBMS.

I have just tested this and works fine.

string test = "Testing 1-2-3";

// convert string to stream
byte[] byteArray = Encoding.ASCII.GetBytes(test);
MemoryStream stream = new MemoryStream(byteArray);

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

If stream has already been written to, you might want to seek to the beginning before first before reading out the text: stream.Seek(0, SeekOrigin.Begin);

Check out javapassion, they have a number of courses that encompass web programming, and were free (until circumstances conspired to make the website need to support itself).

Even with the nominal fee, you get a lot for an entire year. It's a bargain compared to the amount of time you'll be investing.

The other options are to look to Oracle's online tutorials, they lack the glitz of Codeacademy, but are surprisingly good. I haven't read the one on web programming, that might be embedded in the Java EE tutorial(s), which is not tuned for a new beginner to Java.

You can use getTime() method to convert the Date to the number of milliseconds since January 1, 1970. Then you can easy do any arithmetic operations with the dates. Of course you can convert the number back to the Date with setTime(). See here an example.

I would have to say a sleep is a better implementation with a state machine behind it. This would still keep you in control of the application at all times, but allowing any response needed at any specific time. This also will handle timer callbacks that are shorter than the "Processing execution time in the loop"

For example..

<!-- language: c# -->
public enum State
{
    Idle = 0,
    Processing = 1,
    Stop = 100,
}
public void Run()
{
    State state = State.Idle;   // could be a member variable, so a service could stop this too

    double intervalInSeconds = 60;
    System.DateTime nextExecution = System.DateTime.Now.AddSeconds(intervalInSeconds);
    while (state != State.Stop)
    {
        switch (state)
        {
            case State.Idle:

Javascript won't execute within a value attribute. You could do something like this, though:

<input id="date" name="date">

<script type="text/javascript">
  document.getElementById('date').value = Date();
</script>

You'd probably want to format the date as you prefer, because the default output of Date() looks something like: Tue Jun 16 2009 10:47:10 GMT-0400 (Eastern Daylight Time). See this SO question for info about formatting a date.

If you have a form action and an input type="submit" inside form tags, it's going to submit the old fashioned way and basically refresh the page. When doing AJAX type transactions this isn't the desired effect you are after.

Remove the action. Or remove the form altogether, though in cases it does come in handy to serialize to cut your workload. If the form tags remain, move the button outside the form tags, or alternatively make it a link with an onclick or click handler as opposed to an input button. Jquery UI Buttons works great in this case because you can mimic an input button with an a tag element.

It's been mentioned that the difference is largely semantic: people expect a tuple and list to represent different information. But this goes further than a guideline; some libraries actually behave differently based on what they are passed. Take NumPy for example (copied from another post where I ask for more examples):

>>> import numpy as np
>>> a = np.arange(9).reshape(3,3)
>>> a
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])
>>> idx = (1,1)
>>> a[idx]
4
>>> idx = [1,1]
>>> a[idx]
array([[3, 4, 5],
       [3, 4, 5]])

The point is, while NumPy may not be part of the standard library, it's a major Python library, and within NumPy lists and tuples are completely different things.

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

I had a couple of issues with the answers here, such as when you added in the padding, the width of the content was overflowing the box and that I wanted some corner radius. I solved this using the following subclass of UILabel:

#import "MyLabel.h"

#define PADDING 8.0
#define CORNER_RADIUS 4.0

@implementation MyLabel

- (void)drawRect:(CGRect)rect {
 self.layer.masksToBounds = YES;
 self.layer.cornerRadius = CORNER_RADIUS;
 UIEdgeInsets insets = {0, PADDING, 0, PADDING};
 return [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}
- (CGSize) intrinsicContentSize {
 CGSize intrinsicSuperViewContentSize = [super intrinsicContentSize] ;
 intrinsicSuperViewContentSize.width += PADDING * 2 ;
 return intrinsicSuperViewContentSize ;
}

@end

Hope that's helpful to someone! Note that if you wanted padding on the top and bottom, you would need to change this lines:

UIEdgeInsets insets = {0, PADDING, 0, PADDING};

To this:

UIEdgeInsets insets = {PADDING, PADDING, PADDING, PADDING};

And add this line underneath the similar one for width:

intrinsicSuperViewContentSize.height += PADDING * 2 ;

They Differ in Data Type Precedence

Decimal and Numeric are the same functionally but there is still data type precedence, which can be crucial in some cases.

SELECT SQL_VARIANT_PROPERTY(CAST(1 AS NUMERIC) + CAST(1 AS DECIMAL),'basetype')

The resulting data type is numeric because it takes data type precedence.

Exhaustive list of data types by precedence:

Reference link

The first argument is the file you wish to execute, and the second argument is an array of null-terminated strings that represent the appropriate arguments to the file as specified in the man page.

For example:

char *cmd = "ls";
char *argv[3];
argv[0] = "ls";
argv[1] = "-la";
argv[2] = NULL;

execvp(cmd, argv); //This will run "ls -la" as if it were a command

I can't imagine everyone uses all 20 different keypresses to navigate text, 10 or so keys to start adding text, and 18 ways to visually select an inner block. Or do you!?

I do.

In theory, once I have that and start becoming as proficient in VIM as I am in Textmate, then I can start learning the thousands of other VIM commands that will make me more efficient.

That's the right way to do it. Start with basic commands and then pick up ones that improve your productivity. I like following this blog for tips on how to improve my productivity with vim.

Underscore-java library has static method U.formatXml(xmlstring). I am the maintainer of the project. Live example

import com.github.underscore.lodash.U;
import com.github.underscore.lodash.Xml;

public class MyClass {
    public static void main(String[] args) {
        System.out.println(U.formatXml("<a>\n  <b></b>\n  <b></b>\n</a>",
        Xml.XmlStringBuilder.Step.COMPACT));
    }
}

// output: <a><b></b><b></b></a>

The MySQLdb library will actually do this for you, if you use their implementations to build an SQL query string instead of trying to build your own.

Don't do:

sql = "INSERT INTO TABLE_A (COL_A,COL_B) VALUES (%s, %s)" % (val1, val2)
cursor.execute(sql)

Do:

sql = "INSERT INTO TABLE_A (COL_A,COL_B) VALUES (%s, %s)"
cursor.execute(sql, (val1, val2))

The best way to always render a link properly is with the css as follows:

a {cursor: pointer !important}

One should avoid to follow un-necessary things like mentioned in the thread.

Install C++ SDK:

Help > Install New Software > Work with: path for your eclipse version > search for C++ and install C++ sdk development tools.

Example for a path: Mars - http://download.eclipse.org/releases/mars

You don't need to convert it at all:

% perl -e 'print "5.45" + 0.1;'
5.55

Just to add the information I was looking for: pragma mark is Xcode specific, so if you deal with a C++ project that you open in different IDEs, it does not have any effect there. In Qt Creator, for example, it does not add categories for methods, nor generate any warnings/errors.

EDIT

#pragma is a preprocessor directive which comes from C programming language. Its purpose is to specify implementation-dependent information to the compiler - that is, each compiler might choose to interpret this directive as it wants. That said, it is rather considered an extension which does not change/influence the code itself. So compilers might as well ignore it.

Xcode is an IDE which takes advantage of #pragma and uses it in its own specific way. The point is, #pragma is not Xcode and even Objective-C specific.

To change the project name;

1. Select your project in the Project navigator.

2.In the Identity and Type section of the File inspector, enter a new name into the Name field.

3.Press Return.

A dialog is displayed, listing the items in your project that can be renamed. The dialog includes a preview of how the items will appear after the change.

4. To selectively rename items, disable the checkboxes for any items you don’t want to rename. To rename only your app, leave the app selected and deselect all other items.

5. Press "Rename"

Keeping it simple, if you want the request to use the same browsing context as the page you are already looking at then in the Chrome console just do:

window.location="https://www.example.com";

The pass command is what you are looking for. Use pass for any construct that you want to "ignore". Your example uses a conditional expression but you can do the same for almost anything.

For your specific use case, perhaps you'd want to test the opposite condition and only perform an action if the condition is false:

if num2 != num5:
    make_some_changes()

This will be the same as this:

if num2 == num5:
    pass
else:
    make_some_changes()

That way you won't even have to use pass and you'll also be closer to adhering to the "Flatter is better than nested" convention in PEP20.

You can read more about the pass statement in the documentation:

The pass statement does nothing. It can be used when a statement is required syntactically but the program requires no action.

if condition:
    pass

try:
    make_some_changes()
except Exception:
    pass # do nothing

class Foo():
    pass # an empty class definition

def bar():
    pass # an empty function definition

You may check *spell en-GB dictionary used by Mozilla, OpenOffice, plenty of other software.

If no other process is using the port 8080, Eventhough eclipse shows the port 8080 is used while starting the server in eclipse, first you have to stop the server by hitting the stop button in "Configure Tomcat"(which you can find in your start menu under tomcat folder), then try to start the server in eclipse then it will be started.

If any other process is using the port 8080 and as well as you no need to disturb it. then you can change the port.

Unless you've messed with your server, yes it's cached. All the browsers are supposed to handle it the same. Some people (like me) might have their browsers configured so that it doesn't cache any files though. Closing the browser doesn't invalidate the file in the cache. Changing the file on the server should cause a refresh of the file however.

Joda-Time

Alternatively, with the Joda-Time DateTime class.

//convert date to datetime
DateTime datetime = new DateTime(date);
int month = Integer.parseInt(datetime.toString("MM"))

…or…

int month = dateTime.getMonthOfYear();

If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 then rename the ComponentModelCache folder.

The return value (aka exit code) is a value in the range 0 to 255 inclusive. It's used to indicate success or failure, not to return information. Any value outside this range will be wrapped.

To return information, like your number, use

echo "$value"

To print additional information that you don't want captured, use

echo "my irrelevant info" >&2 

Finally, to capture it, use what you did:

 result=$(password_formula)

In other words:

echo "enter: "
        read input

password_formula()
{
        length=${#input}
        last_two=${input:length-2:length}
        first=`echo $last_two| sed -e 's/\(.\)/\1 /g'|awk '{print $2}'`
        second=`echo $last_two| sed -e 's/\(.\)/\1 /g'|awk '{print $1}'`
        let sum=$first+$second
        sum_len=${#sum}
        echo $second >&2
        echo $sum >&2

        if [ $sum -gt 9 ]
        then
               sum=${sum:1}
        fi

        value=$second$sum$first
        echo $value
}
result=$(password_formula)
echo "The value is $result"

In my previous implementation I stored a list of child Fragments to be able to access them later, but this turned out to be a wrong implementation causing huge memory leaks.

I end up using instantiateItem(...) method to get current Fragment:

val currentFragment = adapter?.instantiateItem(viewPager, viewPager.currentItem)

Or to get any other Fragment on position:

val position = 0
val myFirstFragment: MyFragment? = (adapter?.instantiateItem(viewPager, position) as? MyFragment)

From documentation:

Create the page for the given position. The adapter is responsible for adding the view to the container given here, although it only must ensure this is done by the time it returns from finishUpdate(ViewGroup).

select * from table order by random() limit 1000;

If you know how many rows you want, check out tsm_system_rows.

tsm_system_rows

module provides the table sampling method SYSTEM_ROWS, which can be used in the TABLESAMPLE clause of a SELECT command.

This table sampling method accepts a single integer argument that is the maximum number of rows to read. The resulting sample will always contain exactly that many rows, unless the table does not contain enough rows, in which case the whole table is selected. Like the built-in SYSTEM sampling method, SYSTEM_ROWS performs block-level sampling, so that the sample is not completely random but may be subject to clustering effects, especially if only a small number of rows are requested.

First install the extension

CREATE EXTENSION tsm_system_rows;

Then your query,

SELECT *
FROM table
TABLESAMPLE SYSTEM_ROWS(1000);

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

Here's a quick two-liner that I use to quickly create a file if it doesn't exists.

if not os.path.exists(filename):
    open(filename, 'w').close()

IEnumerable<string> result = from myRow in dataTableResult.AsEnumerable()
                             select myRow["server"].ToString() ;

Assuming maven project: Properties file should be in src/main/resources/database folder

jdbc.properties file

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true

ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.

Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.

public interface ServiceMarker {

}

Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker

public interface RepositoryMarker {

}

a.b.c.entities.Student

//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {

    private LocalDateTime fromDate;
    private LocalDateTime toDate;

    //getters setters

}

a.b.c.converters

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {

        if (dateTime == null) {
            return null;
        }
        return Timestamp.valueOf(dateTime);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {

        if (timestamp == null) {
            return null;
        }    
        return timestamp.toLocalDateTime();
    }
}

Hope it helps. Thanks

Those are the basic decision orders that you have in most of the programming language; it helps you to decide the flow of actions that your program is gonna do. The if is telling the compiler that you have a question, and the question is the condition between parenthesis

if (condition) {
    thingsToDo()..
}

the else part is an addition to this structure to tell the compiler what to do if the condition is false

if (condition) {
    thingsToDo()..
} else {
    thingsToDoInOtherCase()..
}

you can combine those to form a else if which is when the first condition is false but you want to do another question before to decide what to do.

if (condition) {
    thingsToDo()..
} else if (condition2) {
    thingsToDoInTheSecondCase()..
}else {
    thingsToDoInOtherCase()..
}

You can use std::find to get an iterator to a value:

#include <algorithm>
std::vector<int>::iterator position = std::find(myVector.begin(), myVector.end(), 8);
if (position != myVector.end()) // == myVector.end() means the element was not found
    myVector.erase(position);

You should use a datastore and proxy in ExtJs. There are plenty of examples of this, and the JSON reader automatically parses the JSON message into the model you specified.

There is no need to use basic Javascript when using ExtJs, everything is different, you should use the ExtJs ways to get everything right. Read there documentation carefully, it's good.

By the way, these examples also hold for Sencha Touch (especially v2), which is based on the same core functions as ExtJs.

Will work fine.

You used the egg files install procedure. This procedure supports installing over git, git+http, git+https, git+ssh, git+git and git+file. Some of these are mentioned.

It's good you can use branches, tags, or hashes to install.

@Steve_K noted it can be slow to install with "git+" and proposed installing via zip file:

pip install https://github.com/user/repository/archive/branch.zip

Alternatively, I suggest you may install using the .whl file if this exists.

pip install https://github.com/user/repository/archive/branch.whl

It's pretty new format, newer than egg files. It requires wheel and setuptools>=0.8 packages. You can find more in here.

Just update of @bfncs answer

I think around Chrome 43 the behavior was changed a little. You still need to enable Preserve log to see, but now redirect shown under Other tab, when loaded document is shown under Doc.

This always confuse me, because I have a lot of networks requests and filter it by type XHR, Doc, JS etc. But in case of redirect the Doc tab is empty, so I have to guess.

In answer to your second question: What does this code do?...

This is fairly standard error-checking code for a Python script that accepts command-line arguments.

So the first if statement translates to: if you haven't passed me an argument, I'm going to tell you how you should pass me an argument in the future, e.g. you'll see this on-screen:

Usage: myscript.py database-name

The next if statement checks to see if the 'database-name' you passed to the script actually exists on the filesystem. If not, you'll get a message like this:

ERROR: Database database-name was not found!

From the documentation:

argv[0] is the script name (it is operating system dependent whether this is a full pathname or not). If the command was executed using the -c command line option to the interpreter, argv[0] is set to the string '-c'. If no script name was passed to the Python interpreter, argv[0] is the empty string.

In the specific case where all the files have the same extension but with different suffix (say number of log file) you use the following:

scp [email protected]:/some/log/folder/some_log_file.* ./

This will copy all files named some_log_file from the given folder within the remote, i.e.- some_log_file.1 , some_log_file.2, some_log_file.3 ....

It looks like jsbeautifier open sourced their tools and packaged them as Python and JS libs, and as CLI tools. It doesn't look like they call out to a web service, but I didn't check too closely. See the github repo with install instructions.

From their docs for Python CLI and library usage:

To beautify using python:

$ pip install jsbeautifier
$ js-beautify file.js

Beautified output goes to stdout.

To use jsbeautifier as a library is simple:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

...or, to specify some options:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

If you want to pass a string instead of a filename, and you are using bash, then you can use process substitution like so:

$ js-beautify <(echo '{"some": "json"}')

Here's the simple way to do It !

string fullPath =openFileDialog1.FileName;
string directory;
directory = fullPath.Substring(0, fullPath.LastIndexOf('\\'));

For those of you who got here looking for the server-side OnClick handler it is OnCheckedChanged

Try marking the field with [NonSerialized()] attribute. This will tell the serializer to ignore the field.

What worked for me on an Amazon EC2 server was:

sudo service mysqld restart

The <prev> tag doesn't exist, but it's probably the <pre> HTML tag to put around debug output, to improve readability. It's not a secret PHP hack. :)

I would go like this (regex explained in comments):

import re

# If you need to use the regex more than once it is suggested to compile it.
pattern = re.compile(r"</{0,}\[\d+>")

# <\/{0,}\[\d+>
# 
# Match the character “<” literally «<»
# Match the character “/” literally «\/{0,}»
#    Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «{0,}»
# Match the character “[” literally «\[»
# Match a single digit 0..9 «\d+»
#    Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
# Match the character “>” literally «>»

subject = """this is a paragraph with<[1> in between</[1> and then there are cases ... where the<[99> number ranges from 1-100</[99>. 
and there are many other lines in the txt files
with<[3> such tags </[3>"""

result = pattern.sub("", subject)

print(result)

If you want to learn more about regex I recomend to read Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan.

This works for me:

string dateTimeString = "21?-?10?-?2014? ?15?:?40?:?30";
dateTimeString = Regex.Replace(dateTimeString, @"[^\u0000-\u007F]", string.Empty);

string inputFormat = "dd-MM-yyyy HH:mm:ss";
string outputFormat = "yyyy-MM-dd HH:mm:ss";
var dateTime = DateTime.ParseExact(dateTimeString, inputFormat, CultureInfo.InvariantCulture);
string output = dateTime.ToString(outputFormat);

Console.WriteLine(output);

I think that ignoring the warning might be legitimate if you want to give the child class the ability to set or override a property that the parent constructor will use right away:

internal class Parent
{
    public Parent()
    {
        Console.WriteLine("Parent ctor");
        Console.WriteLine(Something);
    }

    protected virtual string Something { get; } = "Parent";
}

internal class Child : Parent
{
    public Child()
    {
        Console.WriteLine("Child ctor");
        Console.WriteLine(Something);
    }

    protected override string Something { get; } = "Child";
}

The risk here would be for the child class to set the property from its constructor in which case the change in the value would occur after the base class constructor has been called.

My use case is that I want the child class to provide a specific value or a utility class such as a converter and I don't want to have to call an initialization method on the base.

The output of the above when instantiating the child class is:

Parent ctor
Child
Child ctor
Child

You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ---- to -----BEGIN RSA PUBLIC KEY----- and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).

This article has a good explanation about both formats.

What you get in an RSA PUBLIC KEY is closer to the content of a PUBLIC KEY, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse and -strparse 19, as described in this answer.

EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER:

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim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
  265:d=1  hl=2 l=   3 prim: INTEGER           :010001

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:

   The "ssh-rsa" key format has the following specific encoding:

      string    "ssh-rsa"
      mpint     e
      mpint     n

For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61. The first four bytes (00 00 00 07) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61=ssh-rsa, followed by the exponent of length 1 (00 00 00 01 25) and the modulus of length 256 (00 00 01 00 7f ...).

I was searching how to do something similar in WPF and I got this solution:

<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Vertical" />
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
    <DataTemplate>
        <RadioButton 
            Content="{Binding}" 
            Command="{Binding Path=DataContext.CustomCommand, 
                        RelativeSource={RelativeSource Mode=FindAncestor,      
                        AncestorType={x:Type ItemsControl}} }"
            CommandParameter="{Binding}" />
    </DataTemplate>
</ItemsControl.ItemTemplate>

I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems -which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate is using a DataTemplate, the DataContext of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl type.

If you have not too much data, you can definitely do pagination by just storing all the data in the browser and filtering what's visible at a certain time.

Here's a simple pagination example: http://jsfiddle.net/2ZzZB/56/

That example was on the list of fiddles on the angular.js github wiki, which should be helpful: https://github.com/angular/angular.js/wiki/JsFiddle-Examples

EDIT: http://jsfiddle.net/2ZzZB/16/ to http://jsfiddle.net/2ZzZB/56/ (won't show "1/4.5" if there is 45 results)

I would recommend you to make use of the $.post or $.get syntax of jQuery for simple cases:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
});

If you need to catch the fail cases, just do this:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
}).fail(function(){
      console.log("error");
});

Additionally, if you always send a JSON string, you can use $.getJSON or $.post with one more parameter at the very end.

$.post('superman', { field1: "hello", field2 : "hello2"}, 
     function(returnedData){
        console.log(returnedData);
}, 'json');

For PowerShell 3.0 and later, there is one built in :)

foreach ($item in $array) {
    $array.IndexOf($item)
}

The WPF Toolkit is available. It is free from CodePlex.

It can be downloaded here. There is some commentary here.

You typically set the port at the server using the rmiregistry command. You can set the port on the command line, or it will default to 1099

I have Created for multiline uilabel with underline :

For Font size 8 to 13 set int lineHeight = self.font.pointSize+3;

For font size 14 to 20 set int lineHeight = self.font.pointSize+4;

- (void)drawRect:(CGRect)rect 

{

CGContextRef ctx = UIGraphicsGetCurrentContext();

const CGFloat* colors = CGColorGetComponents(self.textColor.CGColor);

CGContextSetRGBStrokeColor(ctx, colors[0], colors[1], colors[2], 1.0); // RGBA

CGContextSetLineWidth(ctx, 1.0f);
CGSize tmpSize = [self.text sizeWithFont:self.font constrainedToSize:CGSizeMake(self.frame.size.width, 9999)];

int height = tmpSize.height;

int lineHeight = self.font.pointSize+4;    

int maxCount = height/lineHeight;

float totalWidth = [self.text sizeWithFont:self.font constrainedToSize:CGSizeMake(1000, 9999)].width;

for(int i=1;i<=maxCount;i++)

{

    float width=0.0;
    if((i*self.frame.size.width-totalWidth)<=0)
        width = self.frame.size.width;
    else
        width = self.frame.size.width - (i* self.frame.size.width - totalWidth);
    CGContextMoveToPoint(ctx, 0, lineHeight*i-1);
    CGContextAddLineToPoint(ctx, width, lineHeight*i-1);
}

CGContextStrokePath(ctx);

[super drawRect:rect]; 
}

If you don't wish to use 3rd party classes then the following is how you set the post body...

NSURL *aUrl = [NSURL URLWithString:@"http://www.apple.com/"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
                                         cachePolicy:NSURLRequestUseProtocolCachePolicy
                                     timeoutInterval:60.0];

[request setHTTPMethod:@"POST"];
NSString *postString = @"company=Locassa&quality=AWESOME!";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request 
                                                             delegate:self];

Simply append your key/value pair to the post string
