As the official docs of redux suggest, better to export the unconnected component as well.

In order to be able to test the App component itself without having to deal with the decorator, we recommend you to also export the undecorated component:

import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
 
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)

Since the default export is still the decorated component, the import statement pictured above will work as before so you won't have to change your application code. However, you can now import the undecorated App components in your test file like this:

// Note the curly braces: grab the named export instead of default export
import { App } from './App'

And if you need both:

import ConnectedApp, { App } from './App'

In the app itself, you would still import it normally:

import App from './App'

You would only use the named export for tests.

You need something like this: https://github.com/axkibe/lsyncd It is a tool which combines rsync and inotify - the former is a tool that mirrors, with the correct options set, a directory to the last bit. The latter tells the kernel to notify a program of changes to a directory ot file. It says:

It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes.

But - according to Digital Ocean at https://www.digitalocean.com/community/tutorials/how-to-mirror-local-and-remote-directories-on-a-vps-with-lsyncd - it ought to be in the Ubuntu repository!

I have similar requirements, and this tool, which I have yet to try, seems suitable for the task.

            if(temp.right != null)
                q.add(temp.right);
        }
    }
}

}

Adjacency Model + Nested Sets Model

I went for it because I could insert new items to the tree easily (you just need a branch's id to insert a new item to it) and also query it quite fast.

• Every time you need all children of any parent you just query the parent column.
• If you needed all descendants of any parent you query for items which have their lft between lft and rgt of parent.
• If you needed all parents of any node up to the root of the tree, you query for items having lft lower than the node's lft and rgt bigger than the node's rgt and sort the by parent.

I needed to make accessing and querying the tree faster than inserts, that's why I chose this

The only problem is to fix the left and right columns when inserting new items. well I created a stored procedure for it and called it every time I inserted a new item which was rare in my case but it is really fast. I got the idea from the Joe Celko's book, and the stored procedure and how I came up with it is explained here in DBA SE https://dba.stackexchange.com/q/89051/41481

I make moving the files and then do

git add -A

which put in the sataging area all deleted/new files. Here git realizes that the file is moved.

git commit -m "my message"
git push

I do not know why but this works for me.

Recently I found a way around this. I wanted to create a method in the array class with an optional parameter, to keep or discard elements in the array.

The way I simulated this was by passing an array as the parameter, and then checking if the value at that index was nil or not.

class Array
  def ascii_to_text(params)
    param_len = params.length
    if param_len > 3 or param_len < 2 then raise "Invalid number of arguments #{param_len} for 2 || 3." end
    bottom  = params[0]
    top     = params[1]
    keep    = params[2]
    if keep.nil? == false
      if keep == 1
        self.map{|x| if x >= bottom and x <= top then x = x.chr else x = x.to_s end}
      else
        raise "Invalid option #{keep} at argument position 3 in #{p params}, must be 1 or nil"
      end
    else
      self.map{|x| if x >= bottom and x <= top then x = x.chr end}.compact
    end
  end
end

Trying out our class method with different parameters:

array = [1, 2, 97, 98, 99]
p array.ascii_to_text([32, 126, 1]) # Convert all ASCII values of 32-126 to their chr value otherwise keep it the same (That's what the optional 1 is for)

output: ["1", "2", "a", "b", "c"]

Okay, cool that works as planned. Now let's check and see what happens if we don't pass in the the third parameter option (1) in the array.

array = [1, 2, 97, 98, 99]
p array.ascii_to_text([32, 126]) # Convert all ASCII values of 32-126 to their chr value else remove it (1 isn't a parameter option)

output: ["a", "b", "c"]

As you can see, the third option in the array has been removed, thus initiating a different section in the method and removing all ASCII values that are not in our range (32-126)

Alternatively, we could had issued the value as nil in the parameters. Which would look similar to the following code block:

def ascii_to_text(top, bottom, keep = nil)
  if keep.nil?
    self.map{|x| if x >= bottom and x <= top then x = x.chr end}.compact
  else
    self.map{|x| if x >= bottom and x <= top then x = x.chr else x = x.to_s end}
end

Here's where it gets confusing, the text states "If the balance factor of R is 1, it means the insertion occurred on the (external) right side of that node and a left rotation is needed". But from m understanding the text said (as I quoted) that if the balance factor was within [-1, 1] then there was no need for balancing?

Okay, epiphany time.

Consider what a rotation does. Let's think about a left rotation.

 P = parent
 O = ourself (the element we're rotating)
 RC = right child
 LC = left child (of the right child, not of ourself)

 P              10
  \               \
   O               15
    \                \
     RC               20
    /                /
   LC               18

          ?
 P              10
   \               \
     RC              20
   /               /
  O              15
   \               \
   LC              18

 basically, what happens is;

 1. our right child moves into our position
 2. we become the left child of our right child
 3. our right child's left child becomes our right

Now, the big thing you have to notice here - this left rotation HAS NOT CHANGED THE DEPTH OF THE TREE. We're no more balanced for having done it.

But - and here's the magic in AVL - if we rotated the right child to the right FIRST, what we'd have is this...

 P
  \
   O
    \
     LC
      \
       RC

And NOW if we rotate O left, what we get is this...

 P
   \
     LC
    /  \
   O   RC

Magic! we've managed to get rid of a level of the tree - we've made the tree balanced.

Balancing the tree means getting rid of excess depth, and packing the upper levels more completely - which is exactly what we've just done.

That whole stuff about single/double rotations is simply that you have to have your subtree looking like this;

 P
  \
   O
    \
     LC
      \
       RC

before you rotate - and you may have to do a right rotate to get into that state. But if you're already in that state, you only need to do the left rotate.

I was experiencing this problem. My query looked something like:

select a, b, c from sometable where date > '20140101'

My stored procedure was defined like:

create procedure my_procedure (@dtFrom date)
as
select a, b, c from sometable where date > @dtFrom

I changed the datatype to datetime and voila! Went from 30 minutes to 1 minute!

create procedure my_procedure (@dtFrom datetime)
as
select a, b, c from sometable where date > @dtFrom

"Resolve" vs "Recursive" merge strategy

Recursive is the current default two-head strategy, but after some searching I finally found some info about the "resolve" merge strategy.

Taken from O'Reilly book Version Control with Git (Amazon) (paraphrased):

Originally, "resolve" was the default strategy for Git merges.

In criss-cross merge situations, where there is more than one possible merge basis, the resolve strategy works like this: pick one of the possible merge bases, and hope for the best. This is actually not as bad as it sounds. It often turns out that the users have been working on different parts of the code. In that case, Git detects that it's remerging some changes that are already in place and skips the duplicate changes, avoiding the conflict. Or, if these are slight changes that do cause conflict, at least the conflict should be easy for the developer to handle..

I have successfully merged trees using "resolve" that failed with the default recursive strategy. I was getting fatal: git write-tree failed to write a tree errors, and thanks to this blog post (mirror) I tried "-s resolve", which worked. I'm still not exactly sure why... but I think it was because I had duplicate changes in both trees, and resolve "skipped" them properly.

Those three things you said are all true.

• Keys are unique
• To the left are keys less than this one
• To the right are keys greater than this one

I suppose you could reverse your tree and put the smaller keys on the right, but really the "left" and "right" concept is just that: a visual concept to help us think about a data structure which doesn't really have a left or right, so it doesn't really matter.

The DateTime::ToString() method has a string formatter that can be used to output datetime in any required format. See DateTime.ToString Method (String) for more information.

• Well, first System.exit(0) is used to terminate the program and having statements below it is not correct, although the compiler does not throw any errors.
• a plain return; is used in a method of void return type to return the control of execution to its parent method.

Here you go, no frameworks, short and simple:

var el = document.getElementById('elId');
var elTop = el.getBoundingClientRect().top - document.body.getBoundingClientRect().top;

window.addEventListener('scroll', function(){
    if (document.documentElement.scrollTop > elTop){
        el.style.position = 'fixed';
        el.style.top = '0px';
    }
    else
    {
        el.style.position = 'static';
        el.style.top = 'auto';
    }
});

Open Terminal Then

 mysql -u root -p

 eg:- mysql -u shabeer -p

After That Create a Database

 mysql> create database "Name";

 eg:- create database INVESTOR;

Then Select That New Database "INVESTOR"

 mysql> USE INVESTOR;

Select the path of sql file from machine

 mysql> source /home/shabeer/Desktop/new_file.sql;

Then press enter and wait for some times if it's all executed then

 mysql> exit

Well, they don't do the same thing, really.

$_SERVER['REQUEST_METHOD'] contains the request method (surprise).

$_POST contains any post data.

It's possible for a POST request to contain no POST data.

I check the request method — I actually never thought about testing the $_POST array. I check the required post fields, though. So an empty post request would give the user a lot of error messages - which makes sense to me.

ajax()

look for param type

Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>

lines = open(filename).read().splitlines()

Here's a solution to your problem using dplyr's filter function.

Although you can pass your data frame as the first argument to any dplyr function, I've used its %>% operator, which pipes your data frame to one or more dplyr functions (just filter in this case).

Once you are somewhat familiar with dplyr, the cheat sheet is very handy.

> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
   sub day
1    1   1
2    1   2
3    1   3
4    1   4
5    2   1
6    2   2
7    2   3
8    2   4
9    3   1
10   3   2
11   3   3
12   3   4
> print(df <- df %>% filter(!((sub==1 & day==2) | (sub==3 & day==4))))
   sub day
1    1   1
2    1   3
3    1   4
4    2   1
5    2   2
6    2   3
7    2   4
8    3   1
9    3   2
10   3   3

Actually more sane sources are provided by http://suckless.org look at their sbase repository:

git clone git://git.suckless.org/sbase

They are clearer, smarter, simpler and suckless, eg ls.c has just 369 LOC

After that it will be easier to understand more complicated GNU code.

Not a direct answer, but may help some people ending up here.

If you are using GatsbyJS there is a plugin that automatically adds target="_blank" to external links in your markdown.

It's called gatsby-remark-external-links and the usage is like so:

yarn add gatsby-remark-external-links

plugins: [      
  {
    resolve: `gatsby-transformer-remark`,
    options: {
      plugins: [{
        resolve: "gatsby-remark-external-links",
        options: {
          target: "_blank",
          rel: "noopener noreferrer"
        }
      }]
    }
  },

It also takes care of the rel="noopener noreferrer".

Reference the docs if you need more options.

$("div.clickable").click( function(event) { window.location = $(this).attr("url"); event.preventDefault(); });

There are two easy methods:

1. Use backslash \ before double quotes.
2. Use two single quotes instead of double quotes like '' instead of "

For example:

System.out.println("\"Hello\"");                       
System.out.println("''Hello''"); 

Open this Link and select follow the instructions google servers blocks any attempts from unknown servers so once you click on captcha check every thing will be fine

If the table is compressed this will work:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES move nocompress;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

alter table EVAPP_FEES compress;

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.

If you're experiencing a different behaviour, it's time to change for another DBMS.

I found a similar answer as teabot to create a MockFactory that provides the mocks. I used the following example to create the mock factory (since the link to narkisr are dead): http://hg.randompage.org/java/src/407e78aa08a0/projects/bookmarking/backend/spring/src/test/java/org/randompage/bookmarking/backend/testUtils/MocksFactory.java

<bean id="someFacade" class="nl.package.test.MockFactory">
    <property name="type" value="nl.package.someFacade"/>
</bean>

This also helps to prevent that Spring wants to resolve the injections from the mocked bean.

You are asking a lot of questions that you could answer yourself by reading the documentation, so I'll give you a general advice: read it and experiment in the python shell. You'll see that itemgetter returns a callable:

>>> func = operator.itemgetter(1)
>>> func(a)
['Paul', 22, 'Car Dealer']
>>> func(a[0])
8

To do it in a different way, you can use lambda:

a.sort(key=lambda x: x[1])

And reverse it:

a.sort(key=operator.itemgetter(1), reverse=True)

Sort by more than one column:

a.sort(key=operator.itemgetter(1,2))

See the sorting How To.

These names refers to different ways to encode pixel image data (JPG and JPEG are the same thing, and TIFF may just enclose a jpeg with some additional metadata).

These image formats may use different compression algorithms, different color representations, different capability in carrying additional data other than the image itself, and so on.

For web applications, I'd say jpeg or gif is good enough. Jpeg is used more often due to its higher compression ratio, and gif is typically used for light weight animation where a flash (or something similar) is an over kill, or places where transparent background is desired. PNG can be used too, but I don't have much experience with that. BMP and TIFF probably are not good candidates for web applications.

Another solution (from a script, for example):

 sed -i'' -e "s/password=.*\$/password=$pass/g" ~/.my.cnf
 mysql -h $host -u $user $db_name -e "$sql_cmd"

The -i'' option is here for compatibility with Mac OS X. Standard UNIX OSes can use straight -i

Answering the "usefulness" part of the question:

One rather subtle gotcha of using FileChannel over FileOutputStream is that performing any of its blocking operations (e.g. read() or write()) from a thread that's in interrupted state will cause the channel to close abruptly with java.nio.channels.ClosedByInterruptException.

Now, this could be a good thing if whatever the FileChannel was used for is part of the thread's main function, and design took this into account.

But it could also be pesky if used by some auxiliary feature such as a logging function. For example, you can find your logging output suddenly closed if the logging function happens to be called by a thread that's also interrupted.

It's unfortunate this is so subtle because not accounting for this can lead to bugs that affect write integrity.^[1][2]

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

I know this question has an accepted answer, but I feel that it doesn't work in all cases.

For completeness and since I spent too much time on this, here is what we did: we ended up using a function from php.js (which is a pretty nice library for those more familiar with PHP but also doing a little JavaScript every now and then):

http://phpjs.org/functions/strip_tags:535

It seemed to be the only piece of JavaScript code which successfully dealt with all the different kinds of input I stuffed into my application. That is, without breaking it – see my comments about the <script /> tag above.

Clearly many people have answered upon your query of how to make mongoDb work, I'd answer the second part: Regarding an appropriate GUI for mongoDB

My suggestion is, go for MongoChef (now Studio 3T)

You can easily install and use it.

You might want want to refer to (from 03:10- to 08:50): https://www.youtube.com/watch?v=0ws3oIyqieY&index=2&list=PLS1QulWo1RIZtR6bncmSaH8fB81oRl6MP

In my case it was due to 'lower_case_table_names' parameter.

The error number 39 thrown out when I tried to drop the databases which consists upper case table names with lower_case_table_names parameter is enabled.

This is fixed by reverting back the lower case parameter changes to the previous state.

When you view the http://curl.haxx.se/docs/caextract.html page, you will notice in big letters a section called:

Disabling SSL is a bad idea.

I've found an interesting way to solve this using only jQuery:

or

$("#element1").after($("#element2"));

If a value contains a comma, a newline character or a double quote, then the string must be enclosed in double quotes. E.g: "Newline char in this field \n".

If you need to refer them somewhere in the Java Code, you'd rahter put your files into the "res" directory.

And all files in the res folder will be indexed in the R file, which makes it much faster (and much easier!) to load them.

Although there are many answers already and a link to a very good article on change detection, I wanted to give my two cents here. I think the check is there for a reason so I thought about the architecture of my app and realized that the changes in the view can be dealt with by using BehaviourSubject and the correct lifecycle hook. So here's what I did for a solution.

• I use a third-party component (fullcalendar), but I also use Angular Material, so although I made a new plugin for styling, getting the look and feel was a bit awkward because customization of the calendar header is not possible without forking the repo and rolling your own.

• So I ended up getting the underlying JavaScript class, and need to initialize my own calendar header for the component. That requires the ViewChild to be rendered befor my parent is rendered, which is not the way Angular works. This is why I wrapped the value I need for my template in a BehaviourSubject<View>(null):

  calendarView$ = new BehaviorSubject<View>(null);
  

Next, when I can be sure the view is checked, I update that subject with the value from the @ViewChild:

  ngAfterViewInit(): void {
    // ViewChild is available here, so get the JS API
    this.calendarApi = this.calendar.getApi();
  }

  ngAfterViewChecked(): void {
    // The view has been checked and I know that the View object from
    // fullcalendar is available, so emit it.
    this.calendarView$.next(this.calendarApi.view);
  }

Then, in my template, I just use the async pipe. No hacking with change detection, no errors, works smoothly.

Please don't hesitate to ask if you need more details.

thead {
  position: fixed;
  height: 10px; /* This is whatever height you want */
}
  tbody {
  position: fixed;
  margin-top: 10px; /* This has to match the height of thead */
  height: 300px; /* This is whatever height you want */
}

You can use a fake factory to include many methods instead of using instanceof:

public class Message1 implements YourInterface {
   List<YourObject1> list;
   Message1(List<YourObject1> l) {
       list = l;
   }
}

public class Message2 implements YourInterface {
   List<YourObject2> list;
   Message2(List<YourObject2> l) {
       list = l;
   }
}

public class FactoryMessage {
    public static List<YourInterface> getMessage(List<YourObject1> list) {
        return (List<YourInterface>) new Message1(list);
    }
    public static List<YourInterface> getMessage(List<YourObject2> list) {

With JUnit 5 I was able to solve this using the @RepeatedTest annotation:

@RepeatedTest(10)
public void testMyCode() {
    //your test code goes here
}

Note that @Test annotation shouldn't be used along with @RepeatedTest.

Store it anywhere in an accessible location except of the IDE's project folder aka the server's deploy folder, for reasons mentioned in the answer to Uploaded image only available after refreshing the page:

1. Changes in the IDE's project folder does not immediately get reflected in the server's work folder. There's kind of a background job in the IDE which takes care that the server's work folder get synced with last updates (this is in IDE terms called "publishing"). This is the main cause of the problem you're seeing.

2. In real world code there are circumstances where storing uploaded files in the webapp's deploy folder will not work at all. Some servers do (either by default or by configuration) not expand the deployed WAR file into the local disk file system, but instead fully in the memory. You can't create new files in the memory without basically editing the deployed WAR file and redeploying it.

3. Even when the server expands the deployed WAR file into the local disk file system, all newly created files will get lost on a redeploy or even a simple restart, simply because those new files are not part of the original WAR file.

It really doesn't matter to me or anyone else where exactly on the local disk file system it will be saved, as long as you do not ever use getRealPath() method. Using that method is in any case alarming.

The path to the storage location can in turn be definied in many ways. You have to do it all by yourself. Perhaps this is where your confusion is caused because you somehow expected that the server does that all automagically. Please note that @MultipartConfig(location) does not specify the final upload destination, but the temporary storage location for the case file size exceeds memory storage threshold.

So, the path to the final storage location can be definied in either of the following ways:

• Hardcoded:

    File uploads = new File("/path/to/uploads");
  

• Environment variable via SET UPLOAD_LOCATION=/path/to/uploads:

    File uploads = new File(System.getenv("UPLOAD_LOCATION"));
  

• VM argument during server startup via -Dupload.location="/path/to/uploads":

    File uploads = new File(System.getProperty("upload.location"));
  

• *.properties file entry as upload.location=/path/to/uploads:

    File uploads = new File(properties.getProperty("upload.location"));
  

• web.xml <context-param> with name upload.location and value /path/to/uploads:

    File uploads = new File(getServletContext().getInitParameter("upload.location"));
  

• If any, use the server-provided location, e.g. in JBoss AS/WildFly:

    File uploads = new File(System.getProperty("jboss.server.data.dir"), "uploads");
  

Either way, you can easily reference and save the file as follows:

File file = new File(uploads, "somefilename.ext");

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath());
}

Or, when you want to autogenerate an unique file name to prevent users from overwriting existing files with coincidentally the same name:

File file = File.createTempFile("somefilename-", ".ext", uploads);

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath(), StandardCopyOption.REPLACE_EXISTING);
}

How to obtain part in JSP/Servlet is answered in How to upload files to server using JSP/Servlet? and how to obtain part in JSF is answered in How to upload file using JSF 2.2 <h:inputFile>? Where is the saved File?

Note: do not use Part#write() as it interprets the path relative to the temporary storage location defined in @MultipartConfig(location).

This approach always works for me:

String newLine = System.getProperty("line.separator");
String textInNewLine = "this is my first line " + newLine + "this is my second 
line ";

When you want to edit something in Angular you need to insert an ngModel in your html

try this in your sample:

Warning! There's a numbers of errors on the Sun JPA 2 example and the resulting pasted content in Pascal's answer. Please consult this post.

This post and the Sun Java EE 6 JPA 2 example really held back my comprehension of JPA 2. After plowing through the Hibernate and OpenJPA manuals and thinking that I had a good understanding of JPA 2, I still got confused afterwards when returning to this post.

You can run something like this:

sqlcmd -S MyServer -d myDB -E -Q "select col1, col2, col3 from SomeTable" 
       -o "MyData.csv" -h-1 -s"," -w 700

• -h-1 removes column name headers from the result
  
• -s"," sets the column seperator to ,
  
• -w 700 sets the row width to 700 chars (this will need to be as wide as the longest row or it will wrap to the next line)

For checking Safari I used this:

$.browser.safari = ($.browser.webkit && !(/chrome/.test(navigator.userAgent.toLowerCase())));
if ($.browser.safari) {
    alert('this is safari');
}

It works correctly.

preg_replace shim with eval support

This is very inadvisable. But if you're not a programmer, or really prefer terrible code, you could use a substitute preg_replace function to keep your /e flag working temporarily.

/**
 * Can be used as a stopgap shim for preg_replace() calls with /e flag.
 * Is likely to fail for more complex string munging expressions. And
 * very obviously won't help with local-scope variable expressions.
 *
 * @license: CC-BY-*.*-comment-must-be-retained
 * @security: Provides `eval` support for replacement patterns. Which
 *   poses troubles for user-supplied input when paired with overly
 *   generic placeholders. This variant is only slightly stricter than
 *   the C implementation, but still susceptible to varexpression, quote
 *   breakouts and mundane exploits from unquoted capture placeholders.
 * @url: https://stackoverflow.com/q/15454220
 */
function preg_replace_eval($pattern, $replacement, $subject, $limit=-1) {
    # strip /e flag
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    # warn about most blatant misuses at least
    if (preg_match('/\(\.[+*]/', $pattern)) {
        trigger_error("preg_replace_eval(): regex contains (.*) or (.+) placeholders, which easily causes security issues for unconstrained/user input in the replacement expression. Transform your code to use preg_replace_callback() with a sane replacement callback!");
    }
    # run preg_replace with eval-callback
    return preg_replace_callback(
        $pattern,
        function ($matches) use ($replacement) {
            # substitute $1/$2/… with literals from $matches[]
            $repl = preg_replace_callback(
                '/(?<!\\\\)(?:[$]|\\\\)(\d+)/',
                function ($m) use ($matches) {
                    if (!isset($matches[$m[1]])) { trigger_error("No capture group for '$m[0]' eval placeholder"); }
                    return addcslashes($matches[$m[1]], '\"\'\`\$\\\0'); # additionally escapes '$' and backticks
                },
                $replacement
            );
            # run the replacement expression
            return eval("return $repl;");
        },
        $subject,
        $limit
    );
}

In essence, you just include that function in your codebase, and edit preg_replace to preg_replace_eval wherever the /e flag was used.

Pros and cons:

• Really just tested with a few samples from Stack Overflow.
• Does only support the easy cases (function calls, not variable lookups).
• Contains a few more restrictions and advisory notices.
• Will yield dislocated and less comprehensible errors for expression failures.
• However is still a usable temporary solution and doesn't complicate a proper transition to preg_replace_callback.
• And the license comment is just meant to deter people from overusing or spreading this too far.

Replacement code generator

Now this is somewhat redundant. But might help those users who are still overwhelmed with manually restructuring their code to preg_replace_callback. While this is effectively more time consuming, a code generator has less trouble to expand the /e replacement string into an expression. It's a very unremarkable conversion, but likely suffices for the most prevalent examples.

To use this function, edit any broken preg_replace call into preg_replace_eval_replacement and run it once. This will print out the according preg_replace_callback block to be used in its place.

/**
 * Use once to generate a crude preg_replace_callback() substitution. Might often
 * require additional changes in the `return …;` expression. You'll also have to
 * refit the variable names for input/output obviously.
 *
 * >>>  preg_replace_eval_replacement("/\w+/", 'strtopupper("$1")', $ignored);
 */
function preg_replace_eval_replacement($pattern, $replacement, $subjectvar="IGNORED") {
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    $replacement = preg_replace_callback('/[\'\"]?(?<!\\\\)(?:[$]|\\\\)(\d+)[\'\"]?/', function ($m) { return "\$m[{$m[1]}]"; }, $replacement);
    $ve = "var_export";
    $bt = debug_backtrace(0, 1)[0];
    print "<pre><code>
    #----------------------------------------------------
    # replace preg_*() call in '$bt[file]' line $bt[line] with:
    #----------------------------------------------------
    \$OUTPUT_VAR = preg_replace_callback(
        {$ve($pattern, TRUE)},
        function (\$m) {
            return {$replacement};
        },
        \$YOUR_INPUT_VARIABLE_GOES_HERE
    )
    #----------------------------------------------------
    </code></pre>\n";
}

Take in mind that mere copy&pasting is not programming. You'll have to adapt the generated code back to your actual input/output variable names, or usage context.

• Specificially the $OUTPUT = assignment would have to go if the previous preg_replace call was used in an if.
• It's best to keep temporary variables or the multiline code block structure though.

And the replacement expression may demand more readability improvements or rework.

• For instance stripslashes() often becomes redundant in literal expressions.
• Variable-scope lookups require a use or global reference for/within the callback.
• Unevenly quote-enclosed "-$1-$2" capture references will end up syntactically broken by the plain transformation into "-$m[1]-$m[2].

The code output is merely a starting point. And yes, this would have been more useful as an online tool. This code rewriting approach (edit, run, edit, edit) is somewhat impractical. Yet could be more approachable to those who are accustomed to task-centric coding (more steps, more uncoveries). So this alternative might curb a few more duplicate questions.

Just for the record (took me quite a while) before Grzegorzs answer worked for me I had to install "android support repository" through the SDK Manager!

Install it and add the following code above apply plugin: 'android-library' in the build.gradle of actionbarsherlock folder!

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.+'
    }
}

Update:

Instagram are now banning accounts and removing the images based on this method. Please use with caution.

It seems that everyone who has answered this question with something along the lines of it can't be done is somewhat correct. Officially, you cannot post a photo to Instagram with their API. However, if you reverse engineer the API, you can.

Just copy and paste the code above in your text editor, change the few variables accordingly and VOILA! I wrote an article about this and I've done it many times. See a demo here.

You can use this code snippet to scroll:

C#

var element = Driver.FindElement(By.Id("element-id"));
Actions actions = new Actions(Driver);
actions.MoveToElement(element).Perform();

There you have it

Why not use relative units?

.cropText {
    max-width: 20em;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

If the open fails, an error of level E_WARNING is generated. You may use @ to suppress this warning.

    <div class="col-md-12">
      <p style="color: #28a745; font-weight: bold; font-size:25px; text-align: right " >Total Productos a pagar= {{ getTotal() }} {{ getResult() | currency }}
      <button class="btn btn-success" type="submit" [disabled]="!getResult()" (click)="onSubmit()">
        Ver Pedido
      </button>
     </p>
    </div>

Starting with HTML5, <input type="date" /> will do just fine.

The correct answer to this has already been given: no, you can't give the name of an enum, only it's value.

Nevertheless, just for fun, this will give you an enum and a lookup-table all in one and give you a means of printing it by name:

main.c:

#include "Enum.h"

CreateEnum(
        EnumerationName,
        ENUMValue1,
        ENUMValue2,
        ENUMValue3);

int main(void)
{
    int i;
    EnumerationName EnumInstance = ENUMValue1;

    /* Prints "ENUMValue1" */
    PrintEnumValue(EnumerationName, EnumInstance);

    /* Prints:
     * ENUMValue1
     * ENUMValue2
     * ENUMValue3
     */
    for (i=0;i<3;i++)
    {
        PrintEnumValue(EnumerationName, i);
    }
    return 0;
}

Enum.h:

#include <stdio.h>
#include <string.h>

#ifdef NDEBUG
#define CreateEnum(name,...) \
    typedef enum \
    { \
        __VA_ARGS__ \
    } name;
#define PrintEnumValue(name,value)
#else
#define CreateEnum(name,...) \
    typedef enum \
    { \
        __VA_ARGS__ \
    } name; \
    const char Lookup##name[] = \
        #__VA_ARGS__;
#define PrintEnumValue(name, value) print_enum_value(Lookup##name, value)
void print_enum_value(const char *lookup, int value);
#endif

Enum.c

#include "Enum.h"

#ifndef NDEBUG
void print_enum_value(const char *lookup, int value)
{
    char *lookup_copy;
    int lookup_length;
    char *pch;

    lookup_length = strlen(lookup);
    lookup_copy = malloc((1+lookup_length)*sizeof(char));
    strcpy(lookup_copy, lookup);

    pch = strtok(lookup_copy," ,");
    while (pch != NULL)
    {
        if (value == 0)
        {
            printf("%s\n",pch);
            break;
        }
        else
        {
            pch = strtok(NULL, " ,.-");
            value--;
        }
    }

    free(lookup_copy);
}
#endif

I would suggest using FileUtils from Apache Commons IO library.It will create the parent folders of the output file,if they don't exist.while Files.write(out,arrayList,Charset.defaultCharset()); will not do this,throwing exception if the parent directories don't exist.

FileUtils.writeLines(new File("output.txt"), encoding, list);

Assuming you don't know anything about the variable in question, you should take this approach:

if(typeof data === 'number') {
    var remainder = (data % 1);
    if(remainder === 0) {
        // yes, it is an integer
    }
    else if(isNaN(remainder)) {
        // no, data is either: NaN, Infinity, or -Infinity
    }
    else {
        // no, it is a float (still a number though)
    }
}
else {
    // no way, it is not even a number
}

To put it simply:

if(typeof data==='number' && (data%1)===0) {
    // data is an integer
}

     SELECT *  FROM sys.dm_exec_sessions es
  INNER JOIN sys.dm_exec_connections ec
      ON es.session_id = ec.session_id
  CROSS APPLY sys.dm_exec_sql_text(ec.most_recent_sql_handle) where es.session_id=65 under see text contain...

There seem to be several separate issues around oldItems.equals(newItems)

The first part of RT-22463: tableView won't update even if calling items.clear()

// refresh table 
table.getItems().clear();
table.setItems(listEqualToOld);    

that's fixed. Clearing out the old items before setting a new list clears out all old state, thus refreshing the table. Any example where this doesn't work might be a regression.

What's still not working is re-setting items without clearing first

// refresh table
table.setItems(listEqualToOld); 

That's a problem if the table is showing properties that are not involved into an item's equal decision (see example in RT-22463 or Aubin's) and covered - hopefully - by RT-39094

UPDATE: RT-39094 the latter is fixed as well, for 8u40! Should bubble up into the ea in a couple of weeks, speculating on u12 or such.

The technical reason seems to be an equality check in cell's implementation: checking for changes of the item before actually calling updateItem(T, boolean) was introduced to fix performance problems. Reasonable, just to hard-code "change" == old.equals(new) poses problems in some contexts.

A work-around that's fine for me (no formal testing!) is a custom TableRow which jumps in if identity check is required:

/**
 * Extended TableRow that updates its item if equal but not same.
 * Needs custom skin to update cells on invalidation of the 
 * item property.<p>
 * 
 * Looks ugly, as we have to let super doing its job and then
 * re-check the state. No way to hook anywhere else into super 
 * because all is private. <p>
 * 
 * Super might support a configuration option to check against
 * identity vs. against equality.<p>
 * 
 * Note that this is _not_ formally tested! Any execution paths calling
 * <code>updateItem(int)</code> other than through 
 * <code>indexedCell.updateIndex(int)</code> are not handled.

It is also worth noting that even without creating your own model binder multiple different formats may be parsable.

For instance in the US all the following strings are equivalent and automatically get bound to the same DateTime value:

/company/press/may%2001%202008

/company/press/2008-05-01

/company/press/05-01-2008

I'd strongly suggest using yyyy-mm-dd because its a lot more portable. You really dont want to deal with handling multiple localized formats. If someone books a flight on 1st May instead of 5th January you're going to have big issues!

NB: I'm not clear exaclty if yyyy-mm-dd is universally parsed in all cultures so maybe someone who knows can add a comment.

If you want to access your page's global variables, you can do so:

@{
    ViewData["Title"] = "Home Page";

    var LoadingButtons = Model.ToDictionary(person => person, person => false);

    string GetLoadingState (string person) => LoadingButtons[person] ? "is-loading" : string.Empty;
}

Via Jquery:

$(location).attr('href','http://example.com/Registration/Success/');

You can use Object.getOwnPropertyNames() to get all properties that belong to an object, whether enumerable or not. For example:

console.log(Object.getOwnPropertyNames(Math));
//-> ["E", "LN10", "LN2", "LOG2E", "LOG10E", "PI", ...etc ]

You can then use filter() to obtain only the methods:

console.log(Object.getOwnPropertyNames(Math).filter(function (p) {
    return typeof Math[p] === 'function';
}));
//-> ["random", "abs", "acos", "asin", "atan", "ceil", "cos", "exp", ...etc ]

In ES3 browsers (IE 8 and lower), the properties of built-in objects aren't enumerable. Objects like window and document aren't built-in, they're defined by the browser and most likely enumerable by design.

From ECMA-262 Edition 3:

Global Object
There is a unique global object (15.1), which is created before control enters any execution context. Initially the global object has the following properties:

• Built-in objects such as Math, String, Date, parseInt, etc. These have attributes { DontEnum }.
• Additional host defined properties. This may include a property whose value is the global object itself; for example, in the HTML document object model the window property of the global object is the global object itself.

As control enters execution contexts, and as ECMAScript code is executed, additional properties may be added to the global object and the initial properties may be changed.

I should point out that this means those objects aren't enumerable properties of the Global object. If you look through the rest of the specification document, you will see most of the built-in properties and methods of these objects have the { DontEnum } attribute set on them.

Update: a fellow SO user, CMS, brought an IE bug regarding { DontEnum } to my attention.

Instead of checking the DontEnum attribute, [Microsoft] JScript will skip over any property in any object where there is a same-named property in the object's prototype chain that has the attribute DontEnum.

In short, beware when naming your object properties. If there is a built-in prototype property or method with the same name then IE will skip over it when using a for...in loop.

Set the items into display: inline and use :after:

.text span { display: inline }
.break-after:after { content: '\A'; white-space:pre; }

and add the class into your html spans:

<span class="medium break-after">We</span>

when I send only one object from the client to server all works well.

when I attempt to send several objects one after another on the same stream I get StreamCorruptedException.

Actually, your client code is writing one object to the server and reading multiple objects from the server. And there is nothing on the server side that is writing the objects that the client is trying to read.

Check out the link given it has Apache HTTP Server 2.4.2 x86 and x64 Windows Installers http://www.anindya.com/apache-http-server-2-4-2-x86-and-x64-windows-installers/

Nurik's answer was very helpful, but I couldn't get it to work until I found this. In short, if you're using the compatibility library (eg SupportFragmentManager instead of FragmentManager), the syntax of the XML animation files will be different.

A token is a piece of data created by server, and contains information to identify a particular user and token validity. The token will contain the user's information, as well as a special token code that user can pass to the server with every method that supports authentication, instead of passing a username and password directly.

Token-based authentication is a security technique that authenticates the users who attempt to log in to a server, a network, or some other secure system, using a security token provided by the server.

An authentication is successful if a user can prove to a server that he or she is a valid user by passing a security token. The service validates the security token and processes the user request.

After the token is validated by the service, it is used to establish security context for the client, so the service can make authorization decisions or audit activity for successive user requests.

Line number is actually something static, so if you just want it for logging then it could be preprocessed with something like gulp. I've written a small gulp plugin that does exactly that:

var gulp = require('gulp');
var logLine = require('gulp-log-line');
gulp.task('log-line', function() {
    return gulp.src("file.js", {buffer : true})
    //Write here the loggers you use.
        .pipe(logLine(['console.log']))
        .pipe(gulp.dest('./build'))

})

gulp.task('default', ['log-line'])

This will attach the file name and line to all logs from console.log, so console.log(something) will become console.log('filePath:fileNumber', something). The advantage is that now you can concat your files, transpile them... and you will still get the line

This is a old question, and the OP seems to mix C++ and C in his intends/examples. In C, when you pass a array to a function, it's decayed to pointer. So, there is no way to pass the array size except by using a second argument in your function that stores the array size:

void func(int A[]) 
// should be instead: void func(int * A, const size_t elemCountInA)

They are very few cases, where you don't need this, like when you're using multidimensional arrays:

void func(int A[3][whatever here]) // That's almost as if read "int* A[3]"

Using the array notation in a function signature is still useful, for the developer, as it might be an help to tell how many elements your functions expects. For example:

void vec_add(float out[3], float in0[3], float in1[3])

is easier to understand than this one (although, nothing prevent accessing the 4th element in the function in both functions):

void vec_add(float * out, float * in0, float * in1)

If you were to use C++, then you can actually capture the array size and get what you expect:

template <size_t N>
void vec_add(float (&out)[N], float (&in0)[N], float (&in1)[N])
{
    for (size_t i = 0; i < N; i++) 
        out[i] = in0[i] + in1[i];
}

In that case, the compiler will ensure that you're not adding a 4D vector with a 2D vector (which is not possible in C without passing the dimension of each dimension as arguments of the function). There will be as many instance of the vec_add function as the number of dimensions used for your vectors.

This is a side note, but in idiomatic Python, you will often see things like:

if x is None:
    # Some clauses

This is safe, because there is guaranteed to be one instance of the Null Object (i.e., None).

Why not fix a <video> and use z-index:-1 to put it behind all other elements?

html, body { width:100%; height:100%; margin:0; padding:0; }

<div style="position: fixed; top: 0; width: 100%; height: 100%; z-index: -1;">
    <video id="video" style="width:100%; height:100%">
        ....
    </video>
</div>
<div class='content'>
    ....

Demo

If you want it within a container you have to add a container element and a little more CSS

/* HTML */
<div class='vidContain'>
    <div class='vid'>
        <video> ... </video>
    </div>
    <div class='content'> ... The rest of your content ... </div>
</div>

/* CSS */
.vidContain {
    width:300px; height:200px;
    position:relative;
    display:inline-block;
    margin:10px;
}
.vid {
    position: absolute; 
    top: 0; left:0;
    width: 100%; height: 100%; 
    z-index: -1;
}    
.content {
    position:absolute;
    top:0; left:0;
    background: black;
    color:white;
}

This one works fine for me with apis

import requests

data={'Id':id ,'name': name}
r = requests.post( url = 'https://apiurllink', data = data)

To convert a string to a stream you need to decide which encoding the bytes in the stream should have to represent that string - for example you can:

MemoryStream mStrm= new MemoryStream( Encoding.UTF8.GetBytes( contents ) );

For applications/projects: Definitely yes.

The composer documentation states on this (with emphasis):

Commit your application's composer.lock (along with composer.json) into version control.

Like @meza said: You should commit the lock file so you and your collaborators are working on the same set of versions and prevent you from sayings like "But it worked on my computer". ;-)

For libraries: Probably not.

The composer documentation notes on this matter:

Note: For libraries it is not necessarily recommended to commit the lock file (...)

And states here:

For your library you may commit the composer.lock file if you want to. This can help your team to always test against the same dependency versions. However, this lock file will not have any effect on other projects that depend on it. It only has an effect on the main project.

For libraries I agree with @Josh Johnson's answer.

substr(i,j) means that you start from the index i (assuming the first index to be 0) and take next j chars. It does not mean going up to the index j.

Another way to solve this problem (it's not so good practice but looks beauty):

static class Helper
{
    public static object AsSingleParam(this object[] arg)
    {
       return (object)arg;
    }
}

Usage:

f(new object[] { 1, 2, 3 }.AsSingleParam());

Try

for (let row of mytab1.rows) 
{
    for(let cell of row.cells) 
    {
       let val = cell.innerText; // your code below
    }
}

for (let row of mytab1.rows) _x000D_
{_x000D_
    for(let cell of row.cells) _x000D_
    {_x000D_
       console.log(cell.innerText)_x000D_
    }_x000D_
}

<div id="myTabDiv">_x000D_

  </tr>_x000D_
</table>_x000D_
</div>

for ( let [i,row] of [...mytab1.rows].entries() ) _x000D_
{_x000D_
    for( let [j,cell] of [...row.cells].entries() ) _x000D_
    {_x000D_
       console.log(`[${i},${j}] = ${cell.innerText}`)_x000D_
    }_x000D_
}

I found that DataGridViewTextBox values and some JSON objects don't equal Null but instead are "{}" values. Comparing them to Null doesn't work but using these do the trick:

if (cell.Value is System.DBNull)

if (cell.Value == System.DBNull.Value)

A good excerpt I found concerning the difference between Null and DBNull:

Do not confuse the notion of null in an object-oriented programming language with a DBNull object. In an object-oriented programming language, null means the absence of a reference to an object. DBNull represents an uninitialized variant or nonexistent database column.

You can learn more about the DBNull class here.

You are using two WHERE clauses but only one is allowed. Use it like this:

SELECT table1.f_id FROM table1
INNER JOIN table2 ON table2.f_id = table1.f_id
WHERE
  table1.f_com_id = '430'
  AND table1.f_status = 'Submitted'
  AND table2.f_type = 'InProcess'

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

If I invoke clone() method on array of Objects of type A, how will it clone its elements?

The elements of the array will not be cloned.

Will the copy be referencing to the same objects?

Yes.

Or will it call (element of type A).clone() for each of them?

No, it will not call clone() on any of the elements.

I'm using XmlPreprocess tool for config files manipulation. It is using one mapping file for multiple environments(or multiple build targets in your case). You can edit mapping file by Excel. It is very easy to use.

CSS provides only two values for its "list-style-position" - inside and outside. With "inside" second lines are flush with the list points not with the superior line:

In ordered lists, without intervention, if you give "list-style-position" the value "inside", the second line of a long list item will have no indent, but will go back to the left edge of the list (i.e. it will left-align with the number of the item). This is peculiar to ordered lists and doesn't happen in unordered lists.

If you instead give "list-style-position" the value "outside", the second line will have the same indent as the first line.

I had a list with a border and had this problem. With "list-style-position" set to "inside", my list didn't look like I wanted it to. But with "list-style-position" set to "outside", the numbers of the list items fell outside the box.

I solved this by simply setting a wider left margin for the whole list, which pushed the whole list toward the right, back into the position it was in before.

CSS:

ol.classname {margin:0;padding:0;}

ol.classname li {margin:0.5em 0 0 0;padding-left:0;list-style-position:outside;}

HTML:

<ol class="classname" style="margin:0 0 0 1.5em;">

@JaredPar: Yes you can use Shelvesets for reviews but keep in mind that shelvesets can be overwritten by yourself/others and therefore are not long term stable. Therefore for regulatory relevant reviews you should never use a Shelveset as base but rather a checkin (Changeset). For an informal review it is ok but not for a formal (E.g. FTA relevant) review!

Invoking javap to read the bytecode

The javap command takes class-names without the .class extension. Try

javap -c ClassName

Converting .class files back to .java files

javap will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.

To actually decompile (i.e., do the reverse of javac) you will have to use proper decompiler. See for instance the following related question:

• How do I "decompile" Java class files?

Another easy way to do it so that it is referenced in the project folder you want, like "Frameworks", is to:

1. Select "Show the Project navigator"
2. Right-click on the project folder you wish to add the framework to.
3. Select 'Add Files to "YourProjectName"'
4. Browse to the framework - generally under /Developer/SDKs/MacOSXversion.sdk/System/Library/Frameworks
5. Select the one you want.
6. Select "Add"

It will appear in both the project navigator where you want it, as well as in the "Link Binary With Libraries" area of the "Build Phases" pane of your target.

My answer is similar to this one on ServerFault.com.

To Be Conservative

If you want to be more conservative than granting "all privileges", you might want to try something more like these.

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;

The use of public there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.

Access to the Schema

To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.

You will not notice this requirement when first using Postgres. By default every database has a first schema named public. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.

GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;

Excerpt from the Postgres doc:

For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.

For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.

Existing Objects Versus Future

These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

Procedural elements like loops are not part of the SQL language and can only be used inside the body of a procedural language function, procedure (Postgres 11 or later) or a DO statement, where such additional elements are defined by the respective procedural language. The default is PL/pgSQL, but there are others.

Example with plpgsql:

DO
$do$
BEGIN 
   FOR i IN 1..25 LOOP
      INSERT INTO playtime.meta_random_sample
         (col_i, col_id)                       -- declare target columns!
      SELECT  i,     id
      FROM   tbl
      ORDER  BY random()
      LIMIT  15000;
   END LOOP;
END
$do$;

For many tasks that can be solved with a loop, there is a shorter and faster set-based solution around the corner. Pure SQL equivalent for your example:

INSERT INTO playtime.meta_random_sample (col_i, col_id)
SELECT t.*
FROM   generate_series(1,25) i
CROSS  JOIN LATERAL (
   SELECT i, id
   FROM   tbl
   ORDER  BY random()
   LIMIT  15000
   ) t;

A lot of these solutions build on instantiating real Array objects, which can get the job done for a lot of cases but can't support cases like range(Infinity). You could use a simple generator to avoid these problems and support infinite sequences:

function* range( start, end, step = 1 ){
  if( end === undefined ) [end, start] = [start, 0];
  for( let n = start; n < end; n += step ) yield n;
}

Examples:

Array.from(range(10));     // [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
Array.from(range(10, 20)); // [ 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 ]

i = range(10, Infinity);
i.next(); // { value: 10, done: false }
i.next(); // { value: 11, done: false }
i.next(); // { value: 12, done: false }
i.next(); // { value: 13, done: false }
i.next(); // { value: 14, done: false }

I think, from your description, the following would suffice:

DELETE FROM guide_category 
WHERE id_guide NOT IN (SELECT id_guide FROM guide)

I assume, that there are no referential integrity constraints on the tables involved, are there?

This error is related to web.config file. When web.config is not proper or using some features which is not available in IIS, then this issue will come. In my case, I forgot to install URLRewrite module and was referencing it in web.config. It took some time to find the root cause. I started removing sections one by one and checked, only then i was able to find out the actual issue.

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

I took a look at the datejs and stripped out the code necessary to add months to a date handling edge cases (leap year, shorter months, etc):

Date.isLeapYear = function (year) { 
    return (((year % 4 === 0) && (year % 100 !== 0)) || (year % 400 === 0)); 
};

Date.getDaysInMonth = function (year, month) {
    return [31, (Date.isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
};

Date.prototype.isLeapYear = function () { 
    return Date.isLeapYear(this.getFullYear()); 
};

Date.prototype.getDaysInMonth = function () { 
    return Date.getDaysInMonth(this.getFullYear(), this.getMonth());
};

Date.prototype.addMonths = function (value) {
    var n = this.getDate();
    this.setDate(1);
    this.setMonth(this.getMonth() + value);
    this.setDate(Math.min(n, this.getDaysInMonth()));
    return this;
};

This will add "addMonths()" function to any javascript date object that should handle edge cases. Thanks to Coolite Inc!

Use:

var myDate = new Date("01/31/2012");
var result1 = myDate.addMonths(1);

var myDate2 = new Date("01/31/2011");
var result2 = myDate2.addMonths(1);

->> newDate.addMonths -> mydate.addMonths

result1 = "Feb 29 2012"

result2 = "Feb 28 2011"

I meet the same problem, @progrAmmar enlightened me, "took a closer look at the user table in mysql database".

My problem is not ssl_type, instead of the first field:Host. I changed the value by using

update user set Host='localhost' where User='root' and Host='%';

in mysqld_safe --skip-grant-tables model.

Then it works well.

I got the same problem and this is how i solved. :

1. Right click your Spring MVC project, choose Run As -> Maven install. Observe the output console to see the installation progress. After the installation is finished, you can continue to the next step.

2. Right click your Spring MVC project, choose Maven -> Update Project.

3. Choose your project and click OK. Wait until update process is finished.
4. The error still yet, then do Project->Clean and then be sure you have selected our project directory and then do the follow Project->Build.

Check out the language reference:

http://msdn.microsoft.com/en-us/library/aa195811(office.11).aspx

expression.Open(FileName, UpdateLinks, ReadOnly, Format, Password, WriteResPassword, IgnoreReadOnlyRecommended, Origin, Delimiter, Editable, Notify, Converter, AddToMru, Local, CorruptLoad)

You should put this line in your application context:

<context:component-scan base-package="com.cinebot.service" />

Read more about Automatically detecting classes and registering bean definitions in documentation.

Existing solutions did not work for me (details below). What finally worked was to implement readline using read(1) (based on this answer). The latter does not block:

from subprocess import Popen, PIPE
from threading import Thread
def process_output(myprocess): #output-consuming thread
    nextline = None
    buf = ''
    while True:
        #--- extract line using read(1)
        out = myprocess.stdout.read(1)
        if out == '' and myprocess.poll() != None: break
        if out != '':
            buf += out
            if out == '\n':
                nextline = buf
                buf = ''
        if not nextline: continue
        line = nextline
        nextline = None

        #--- do whatever you want with line here
        print 'Line is:', line
    myprocess.stdout.close()

myprocess = Popen('myprogram.exe', stdout=PIPE) #output-producing process
p1 = Thread(target=process_output, args=(dcmpid,)) #output-consuming thread
p1.daemon = True
p1.start()

#--- do whatever here and then kill process and thread if needed
if myprocess.poll() == None: #kill process; will automatically stop thread
    myprocess.kill()
    myprocess.wait()
if p1 and p1.is_alive(): #wait for thread to finish
    p1.join()

Why existing solutions did not work:

1. Solutions that require readline (including the Queue based ones) always block. It is difficult (impossible?) to kill the thread that executes readline. It only gets killed when the process that created it finishes, but not when the output-producing process is killed.
2. Mixing low-level fcntl with high-level readline calls may not work properly as anonnn has pointed out.
3. Using select.poll() is neat, but doesn't work on Windows according to python docs.
4. Using third-party libraries seems overkill for this task and adds additional dependencies.

I had a similar problem I was calling the render method incorrectly

Gave an error:

render = () => {
    ...
}

instead of

correct:

render(){
    ...
}

If you want to disable unreferenced local variable write in some header

template<class T>
void ignore (const T & ) {}

and use

catch(const Except & excpt) {
    ignore(excpt); // No warning
    // ...  
} 

Any unit test you could create by just pressing a button would not be worth anything. How is the tool to know what parameters to pass your method and what to expect back? Unless I'm misunderstanding your expectations.

Close to that is something like FitNesse, where you can set up tests, then separately you set up a wiki page with your test data, and it runs the tests with that data, publishing the results as red/greens.

If you would be happy to make test writing much faster, I would suggest Mockito, a mocking framework that lets you very easily mock the classes around the one you're testing, so there's less setup/teardown, and you know you're really testing that one class instead of a dependent of it.

Would you please try with below code block, which is exactly what you're looking for:

SqlConnection conn = new SqlConnection
{
    ConnectionString = "Data Source=" + System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\Database.sdf"
};

You can also use a filler to fill the remaining space.

<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="filler"></div>
    <div class="c"><a href="#">Contact</a></div>
</div>

.filler{
    flex-grow: 1;
}

I have updated the solution with 3 different versions. This because of the discussion of the validity of using an additional filler element. If you run the code snipped you see that all solutions do different things. For instance setting the filler class on item b will make this item fill the remaining space. This has the benefit that there is no 'dead' space that is not clickable.

<div class="mainfiller">_x000D_
    <div class="a"><a href="#">Home</a></div>_x000D_
    <div class="b"><a href="#">Some title centered</a></div>_x000D_
    <div class="filler"></div>_x000D_
    <div class="c"><a href="#">Contact</a></div>_x000D_
</div>_x000D_
_x000D_
<div class="mainfiller">_x000D_
    <div class="a"><a href="#">Home</a></div>_x000D_
    <div class="filler b"><a href="#">Some title centered</a></div>_x000D_
    <div class="c"><a href="#">Contact</a></div>_x000D_
</div>_x000D_
_x000D_
_x000D_
_x000D_
<div class="main">_x000D_
    <div class="a"><a href="#">Home</a></div>_x000D_
    <div class="b"><a href="#">Some title centered</a></div>_x000D_
    <div class="c"><a href="#">Contact</a></div>_x000D_
</div>_x000D_
_x000D_
<style>_x000D_
.main { display: flex; justify-content: space-between; }_x000D_
.mainfiller{display: flex;}_x000D_
.filler{flex-grow:1; text-align:center}_x000D_
.a, .b, .c { background: yellow; border: 1px solid #999; }_x000D_
</style>

The accepted answer worked for me until deployed on JDK 1.8u91. Then I realized it failed at field.set(null, newValue); line when I had read the value via reflection before calling of setFinalStatic method.

Probably the read caused somehow different setup of Java reflection internals (namely sun.reflect.UnsafeQualifiedStaticObjectFieldAccessorImpl in failing case instead of sun.reflect.UnsafeStaticObjectFieldAccessorImpl in success case) but I didn't elaborate it further.

Since I needed to temporarily set new value based on old value and later set old value back, I changed signature little bit to provide computation function externally and also return old value:

public static <T> T assignFinalField(Object object, Class<?> clazz, String fieldName, UnaryOperator<T> newValueFunction) {
    Field f = null, ff = null;
    try {
        f = clazz.getDeclaredField(fieldName);
        final int oldM = f.getModifiers();
        final int newM = oldM & ~Modifier.FINAL;
        ff = Field.class.getDeclaredField("modifiers");
        ff.setAccessible(true);
        ff.setInt(f,newM);
        f.setAccessible(true);

        T result = (T)f.get(object);
        T newValue = newValueFunction.apply(result);

        f.set(object,newValue);
        ff.setInt(f,oldM);

        return result;
    } ...

However for general case this would not be sufficient.

The <font> tag has been deprecated, at least in XHTML. That means that it's use is officially "frowned upon," and there is no guarantee that future browsers will continue to display the text as you intended.

You have to use CSS. Go with the <span> tag, or a separate style sheet. According to its specification, the <span> tag has no semantic meaning and just allows you to change the style of a particular region.

You use uninstall the app and change the sharedPreferences name then run this application. I think it will resolve the issue.

A sample code to retrieve values from sharedPreferences you can use the following set of code,

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyValue, ""));

Which alignment technique you use depends on your circumstances but the basic one is float: right;:

<input type="button" value="Click Me" style="float: right;">

You'll probably want to clear your floats though but that can be done with overflow:hidden on the parent container or an explicit <div style="clear: both;"></div> at the bottom of the container.

For example: http://jsfiddle.net/ambiguous/8UvVg/

Floated elements are removed from the normal document flow so they can overflow their parent's boundary and mess up the parent's height, the clear:both CSS takes care of that (as does overflow:hidden). Play around with the JSFiddle example I added to see how floating and clearing behave (you'll want to drop the overflow:hidden first though).

Use the following command to get connected to your MySQL database

mysql -u USERNAME -h HOSTNAME -p

None of the existing answers worked for me.

I was using worktrees, so there is no .git folder.

You'll need to go back to your main repo. Inside that, delete .git/worktrees/<name_of_tree>/index

Then run git reset as per other answers.

Maybe this is helpfull to someone after few years. New way, on Androidx, of getting SharedPreferences() inside fragment is to implement into gradle dependencies

implementation "androidx.preference:preference:1.1.1"

and then, inside fragment call

SharedPreferences preferences;
preferences = androidx.preference.PreferenceManager.getDefaultSharedPreferences(getActivity());

My approach with a reducer:

myArray = [_x000D_
  {group: "one", color: "red"},_x000D_
  {group: "two", color: "blue"},_x000D_
  {group: "one", color: "green"},_x000D_
  {group: "one", color: "black"}_x000D_
]_x000D_
_x000D_
console.log(myArray.reduce( (acc, curr) => {_x000D_
  const itemExists = acc.find(item => curr.group === item.group)_x000D_
  if(itemExists){_x000D_
    itemExists.color = [...itemExists.color, curr.color]_x000D_
  }else{_x000D_
    acc.push({group: curr.group, color: [curr.color]})_x000D_
  }_x000D_
  return acc;_x000D_
}, []))

First and foremost, I highly recommend you buy the PDF/E-Book from PHP Architect. It's US$20, but is the only straightforward "Here's how Magento works" resource I've been able to find. I've also started writing Magento tutorials at my own website.

Second, if you have a choice, and aren't an experienced programmer or don't have access to an experienced programmer (ideally in PHP and Java), pick another cart. Magento is well engineered, but it was engineered to be a shopping cart solution that other programmers can build modules on top of. It was not engineered to be easily understood by people who are smart, but aren't programmers.

Third, Magento MVC is very different from the Ruby on Rails, Django, CodeIgniter, CakePHP, etc. MVC model that's popular with PHP developers these days. I think it's based on the Zend model, and the whole thing is very Java OOP-like. There's two controllers you need to be concerned about. The module/frontName controller, and then the MVC controller.

Fourth, the Magento application itself is built using the same module system you'll be using, so poking around the core code is a useful learning tactic. Also, a lot of what you'll be doing with Magento is overriding existing classes. What I'm covering here is creating new functionality, not overriding. Keep this in mind when you're looking at the code samples out there.

I'm going to start with your first question, showing you how to setup a controller/router to respond to a specific URL. This will be a small novel. I might have time later for the model/template related topics, but for now, I don't. I will, however, briefly speak to your SQL question.

Magento uses an EAV database architecture. Whenever possible, try to use the model objects the system provides to get the information you need. I know it's all there in the SQL tables, but it's best not to think of grabbing data using raw SQL queries, or you'll go mad.

Final disclaimer. I've been using Magento for about two or three weeks, so caveat emptor. This is an exercise to get this straight in my head as much as it is to help Stack Overflow.

Create a module

All additions and customizations to Magento are done through modules. So, the first thing you'll need to do is create a new module. Create an XML file in app/modules named as follows

cd /path/to/store/app
touch etc/modules/MyCompanyName_HelloWorld.xml

<?xml version="1.0"?>
<config>
     <modules>
        <MyCompanyName_HelloWorld>
            <active>true</active>
            <codePool>local</codePool>
        </MyCompanyName_HelloWorld>
     </modules>
</config>

MyCompanyName is a unique namespace for your modifications, it doesn't have to be your company's name, but that the recommended convention my magento. HelloWorld is the name of your module.

Clear the application cache

Now that the module file is in place, we'll need to let Magento know about it (and check our work). In the admin application

1. Go to System->Cache Management
2. Select Refresh from the All Cache menu
3. Click Save Cache settings

Now, we make sure that Magento knows about the module

1. Go to System->Configuration
2. Click Advanced
3. In the "Disable modules output" setting box, look for your new module named "MyCompanyName_HelloWorld"

If you can live with the performance slow down, you might want to turn off the application cache while developing/learning. Nothing is more frustrating then forgetting the clear out the cache and wondering why your changes aren't showing up.

Setup the directory structure

Next, we'll need to setup a directory structure for the module. You won't need all these directories, but there's no harm in setting them all up now.

mkdir -p app/code/local/MyCompanyName/HelloWorld/Block
mkdir -p app/code/local/MyCompanyName/HelloWorld/controllers
mkdir -p app/code/local/MyCompanyName/HelloWorld/Model
mkdir -p app/code/local/MyCompanyName/HelloWorld/Helper
mkdir -p app/code/local/MyCompanyName/HelloWorld/etc
mkdir -p app/code/local/MyCompanyName/HelloWorld/sql

And add a configuration file

touch app/code/local/MyCompanyName/HelloWorld/etc/config.xml

and inside the configuration file, add the following, which is essentially a "blank" configuration.

<?xml version="1.0"?>
<config>
    <modules>
        <MyCompanyName_HelloWorld>
            <version>0.1.0</version>
        </MyCompanyName_HelloWorld>
    </modules>
</config>

Oversimplifying things, this configuration file will let you tell Magento what code you want to run.

Setting up the router

Next, we need to setup the module's routers. This will let the system know that we're handling any URLs in the form of

http://example.com/magento/index.php/helloworld

So, in your configuration file, add the following section.

<config>
<!-- ... -->
    <frontend>
        <routers>
            <!-- the <helloworld> tagname appears to be arbitrary, but by
            convention is should match the frontName tag below-->
            <helloworld>
                <use>standard</use>
                <args>
                    <module>MyCompanyName_HelloWorld</module>
                    <frontName>helloworld</frontName>
                </args>
            </helloworld>
        </routers>
    </frontend>
<!-- ... -->
</config>

What you're saying here is "any URL with the frontName of helloworld ...

http://example.com/magento/index.php/helloworld

should use the frontName controller MyCompanyName_HelloWorld".

So, with the above configuration in place, when you load the helloworld page above, you'll get a 404 page. That's because we haven't created a file for our controller. Let's do that now.

touch app/code/local/MyCompanyName/HelloWorld/controllers/IndexController.php

Now try loading the page. Progress! Instead of a 404, you'll get a PHP/Magento exception

Controller file was loaded but class does not exist

So, open the file we just created, and paste in the following code. The name of the class needs to be based on the name you provided in your router.

<?php
class MyCompanyName_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action{
    public function indexAction(){
        echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here";
    }
}

What we've just setup is the module/frontName controller. This is the default controller and the default action of the module. If you want to add controllers or actions, you have to remember that the tree first part of a Magento URL are immutable they will always go this way http://example.com/magento/index.php/frontName/controllerName/actionName

So if you want to match this url

http://example.com/magento/index.php/helloworld/foo

You will have to have a FooController, which you can do this way :

touch app/code/local/MyCompanyName/HelloWorld/controllers/FooController.php

<?php
class MyCompanyName_HelloWorld_FooController extends Mage_Core_Controller_Front_Action{
    public function indexAction(){
        echo 'Foo Index Action';
    }

    public function addAction(){
        echo 'Foo add Action';
    }

    public function deleteAction(){
        echo 'Foo delete Action';
    }
}

Please note that the default controller IndexController and the default action indexAction can by implicit but have to be explicit if something come after it. So http://example.com/magento/index.php/helloworld/foo will match the controller FooController and the action indexAction and NOT the action fooAction of the IndexController. If you want to have a fooAction, in the controller IndexController you then have to call this controller explicitly like this way : http://example.com/magento/index.php/helloworld/index/foo because the second part of the url is and will always be the controllerName. This behaviour is an inheritance of the Zend Framework bundled in Magento.

You should now be able to hit the following URLs and see the results of your echo statements

http://example.com/magento/index.php/helloworld/foo
http://example.com/magento/index.php/helloworld/foo/add
http://example.com/magento/index.php/helloworld/foo/delete

So, that should give you a basic idea on how Magento dispatches to a controller. From here I'd recommended poking at the existing Magento controller classes to see how models and the template/layout system should be used.

If you already have the target object, so you don't want to create it anew (like if updating an array) you must copy the properties.
If have done it this way:

Object.keys(source).forEach((key) => {
    copy[key] = source[key]
})

Praise is due. (look at headline "version 2")

I know that this question is about 6+ years old, but the answer by @Kyle doesn't work.

Using this

setSize(width - (getInsets().left + getInsets().right), height - (getInsets().top + getInsets().bottom));

But this always work in any size:

setSize(width + 14, height + 7);

If you don't want the border to border, and only want the white area, here:

setSize(width + 16, height + 39);

Also this only works on Windows 10, for MacOS users, use @ben's answer.

This is the simple example to use both of them:

import {
  Directive, HostListener, HostBinding
}
from '@angular/core';

@Directive({
  selector: '[Highlight]'
})
export class HighlightDirective {
  @HostListener('mouseenter') mouseover() {
    this.backgroundColor = 'green';
  };

  @HostListener('mouseleave') mouseleave() {
    this.backgroundColor = 'white';
  }

  @HostBinding('style.backgroundColor') get setColor() {
     return this.backgroundColor;
  };

  private backgroundColor = 'white';
  constructor() {}

}

Introduction:

1. HostListener can bind an event to the element.

2. HostBinding can bind a style to the element.

3. this is directive, so we can use it for

   Some Text

4. So according to the debug, we can find that this div has been binded style = "background-color:white"

   Some Text

5. we also can find that EventListener of this div has two event: mouseenter and mouseleave. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.

You must initialize your List seeAlso :

List<String> seeAlso = new Vector<String>();

or

List<String> seeAlso = new ArrayList<String>();

When Command Extensions are enabled (Windows XP and newer, roughly), you can use the syntax %~nF (where F is the variable and ~n is the request for its name) to only get the filename.

FOR /R C:\Directory %F in (*.*) do echo %~nF

should echo only the filenames.

Here's a solution that has worked pretty well for me:

List<String> lines = Arrays.asList(
    new Scanner(new File(file)).useDelimiter("\\Z").next().split("\\r?\\n")
);

If you don't want empty lines, you can also do:

List<String> lines = Arrays.asList(
    new Scanner(new File(file)).useDelimiter("\\Z").next().split("[\\r\\n]+")
);

<p:ajax listener="#{my.handleChange}" update="id of component that need to be rerender after change" process="@this" />



import javax.faces.component.UIOutput;
import javax.faces.event.AjaxBehaviorEvent;

public void handleChange(AjaxBehaviorEvent vce){  
  String name= (String) ((UIOutput) vce.getSource()).getValue();
}

You can do:

flask.jsonify(**data)

or

flask.jsonify(id=str(album.id), title=album.title)

For now, semantically closest one would be a tuple with fixed number of elements.

typealias buffer = (
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,

    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode)

But this is (1) very uncomfortable to use and (2) memory layout is undefined. (at least unknown to me)

I was having same problem and @webtrifusion's answer helped find the solution.

My model was using the Bind(Exclude) attribute on the entity's ID which was causing the value of the entity's ID to be zero on HttpPost.

namespace OrderUp.Models
{
[Bind(Exclude = "OrderID")]
public class Order
{
    [ScaffoldColumn(false)]
    public int OrderID { get; set; }

    [ScaffoldColumn(false)]
    public System.DateTime OrderDate { get; set; }

    [Required(ErrorMessage = "Name is required")]
    public string Username { get; set; }
    }
}   

You can write a pretty simple embedded Jetty Java server.

Embedded Jetty means that the server (Jetty) shipped together with the application as opposed of deploying the application on external Jetty server.

So if in non-embedded approach your webapp built into WAR file which deployed to some external server (Tomcat / Jetty / etc), in embedded Jetty, you write the webapp and instantiate the jetty server in the same code base.

An example for embedded Jetty Java server you can git clone and use: https://github.com/stas-slu/embedded-jetty-java-server-example

Try this!

git log | grep -b3 "Build 0051"

This works regardless of the size of its contents

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

source: https://css-tricks.com/quick-css-trick-how-to-center-an-object-exactly-in-the-center/

Because of your password. You can see password validate configuration metrics using the following query in MySQL client:

SHOW VARIABLES LIKE 'validate_password%';

The output should be something like that :

+--------------------------------------+-------+
| Variable_name                        | Value |
+--------------------------------------+-------+
| validate_password.check_user_name    | ON    |
| validate_password.dictionary_file    |       |
| validate_password.length             | 6     |
| validate_password.mixed_case_count   | 1     |
| validate_password.number_count       | 1     |
| validate_password.policy             | LOW   |
| validate_password.special_char_count | 1     |
+--------------------------------------+-------+

then you can set the password policy level lower, for example:

SET GLOBAL validate_password.length = 6;
SET GLOBAL validate_password.number_count = 0;

Check the MySQL Documentation.

not need to run queries to sidable FKs on sql. If you have a FK from table A to B, you should:

• delete data from table A
• delete data from table B
• insert data on B
• insert data on A

You can also tell the destination not to check constraints

There are some funnies restoring old databases into SQL 2008 via the guy; have you tried doing it via TSQL ?

Use Master
Go
RESTORE DATABASE YourDB
FROM DISK = 'C:\YourBackUpFile.bak'
WITH MOVE 'YourMDFLogicalName' TO 'D:\Data\YourMDFFile.mdf',--check and adjust path
MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf' 

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

with below code you can listen SpaceBar pressing , in middle of your console execution and pause until another key is pressed and also listen for EscapeKey for breaking the main loop

static ConsoleKeyInfo cki = new ConsoleKeyInfo();


while(true) {
      if (WaitOrBreak()) break;
      //your main code
}

 private static bool WaitOrBreak(){
        if (Console.KeyAvailable) cki = Console.ReadKey(true);
        if (cki.Key == ConsoleKey.Spacebar)
        {
            Console.Write("waiting..");
            while (Console.KeyAvailable == false)
            {
                Thread.Sleep(250);Console.Write(".");
            }
            Console.WriteLine();
            Console.ReadKey(true);
            cki = new ConsoleKeyInfo();
        }
        if (cki.Key == ConsoleKey.Escape) return true;
        return false;
    }

You can use dev tools profiler.

console.time('Timer name');
//do critical time stuff
console.timeEnd('Timer name');

"Timer name" must be the same. You can use multiple instances of timer with different names.

Primary Key: Is composed of partition key(s) [and optional clustering keys(or columns)]
Partition Key: The hash value of Partition key is used to determine the specific node in a cluster to store the data
Clustering Key: Is used to sort the data in each of the partitions(or responsible node and it's replicas)

Compound Primary Key: As said above, the clustering keys are optional in a Primary Key. If they aren't mentioned, it's a simple primary key. If clustering keys are mentioned, it's a Compound primary key.

Composite Partition Key: Using just one column as a partition key, might result in wide row issues (depends on use case/data modeling). Hence the partition key is sometimes specified as a combination of more than one column.

Regarding confusion of which one is mandatory, which one can be skipped etc. in a query, trying to imagine Cassandra as a giant HashMap helps. So in a HashMap, you can't retrieve the values without the Key.
Here, the Partition keys play the role of that key. So each query needs to have them specified. Without which Cassandra won't know which node to search for.
The clustering keys (columns, which are optional) help in further narrowing your query search after Cassandra finds out the specific node(and it's replicas) responsible for that specific Partition key.

A few caveats not covered in most answers:

• Check against multiple items (some should be deleted, some should remain)
• Skip the first option (-Select-) on some option lists

A take on these:

const eligibleOptions = ['800000002', '800000001'];
let optionsList = document.querySelector("select#edit-salutation");
for (let i = 1; i<optionsList.length; i++) {
    if(eligibleOptions.indexOf(optionsList.options[i].value) === -1) {
        cbxSal.remove(i);
        i--;
    }
}

If you are making the fetch call to your localhost which I'm guessing is run by node.js in the same directory as your backbone code, than it will most likely be on http://localhost:3000 or something like that. Than this should be your model:

var model = Backbone.Model.extend({
    url: '/item'
});

And in your node.js you now have to accept that call like this:

app.get('/item', function(req, res){
    res.send('some info here');
});

Edit: Don't use this solution with FreeMarker 2.3.25 and up, especially not .get(prop). See other answers.

You use the built-in keys function, e.g. this should work:

<#list user?keys as prop>
    ${prop} = ${user.get(prop)}
</#list>  

No, [^\x20-\x7E] is not ASCII.

This is real ASCII:

 [^\x00-\x7F]

Otherwise, it will trim out newlines and other special characters that are part of the ASCII table!

You could also use the .add() function:

 df.loc[:,'variance'] = df.loc[:,'budget'].add(df.loc[:,'actual'])

It took me a while to figure this out too. url_for in Flask looks for endpoints that you specified in the routes.py script.

So if you have a decorator in your routes.py file like @blah.route('/folder.subfolder') then Flask will recognize the command {{ url_for('folder.subfolder') , filename = "some_image.jpg" }} . The 'folder.subfolder' argument sends it to a Flask endpoint it recognizes.

However let us say that you stored your image file, some_image.jpg, in your subfolder, BUT did not specify this subfolder as a route endpoint in your flask routes.py, your route decorator looks like @blah.routes('/folder'). You then have to ask for your image file this way: {{ url_for('folder'), filename = 'subfolder/some_image.jpg' }}

I.E. you tell Flask to go to the endpoint it knows, "folder", then direct it from there by putting the subdirectory path in the filename argument.

SELECT * FROM TableName WHERE CHARINDEX('''',ColumnName) > 0 

When you have column with large amount of nvarchar data and millions of records, general 'LIKE' kind of search using percentage symbol will degrade the performance of the SQL operation.

While CHARINDEX inbuilt TSQL function is much more faster and there won't be any performance loss.

Reference SO post for comparative view.

There is number of methods to allocate an array of intrinsic type and all of these method are correct, though which one to choose, depends...

Manual initialisation of all elements in loop

int* p = new int[10];
for (int i = 0; i < 10; i++)
    p[i] = 0;

Using std::memset function from <cstring>

int* p = new int[10];
std::memset(p, 0, sizeof *p * 10);

Using std::fill_n algorithm from <algorithm>

int* p = new int[10];
std::fill_n(p, 10, 0);

Using std::vector container

std::vector<int> v(10); // elements zero'ed

If C++11 is available, using initializer list features

int a[] = { 1, 2, 3 }; // 3-element static size array
vector<int> v = { 1, 2, 3 }; // 3-element array but vector is resizeable in runtime

The simpliest way to understand it is that DateTime is a struct. When you initialize a struct it's initialize to it's minimum value : DateTime.Min

Therefore there is no difference between default(DateTime) and new DateTime() and DateTime.Min

For me, my svgs looked different when having them as img and svg. So my solution converts the img to csv, changes styles internally and back to img (although it requires a bit more work), I believe "blob" also has better compatibility than the upvoted answer using "mask".

  let img = yourimgs[0];
  if (img.src.includes(".svg")) {
    var ajax = new XMLHttpRequest();
    ajax.open("GET", img.src, true);
    ajax.send();
    ajax.onload = function (e) {
     
      svg = e.target.responseText;

     
      svgText = "";
      //change your svg-string as youd like, for example
      // replacing the hex color between "{fill:" and ";"
      idx = svg.indexOf("{fill:");
      substr = svg.substr(idx + 6);
      str1 = svg.substr(0, idx + 6);
      str2 = substr.substr(substr.indexOf(";"));
      svgText = str1 + "#ff0000" + str2;
      

      let blob = new Blob([svgText], { type: "image/svg+xml" });
      let url = URL.createObjectURL(blob);
      let image = document.createElement("img");
      image.src = url;
      image.addEventListener("load", () => URL.revokeObjectURL(url), {
        once: true,
      });
      img.replaceWith(image);
    };
  }

If using angular-ui-router, then this is the correct solution: https://github.com/angular-ui/ui-router/wiki#resolve

Basically, you declare a set of dependecies to "resolve" before the controller is instantiated. You may declare dependencies for each of your "states". These dependencies are then passed in the controller's "constructor".

I've released a library to help with this. Pulls all possible input values, actually, but also includes which radio button was checked. You can check it out at https://github.com/mazondo/formalizedata

It'll give you a js object of the answers, so a form like:

<form>
<input type="radio" name"favorite-color" value="blue" checked> Blue
<input type="radio" name="favorite-color" value="red"> Red
</form>

will give you:

$("form").formalizeData()
{
  "favorite-color" : "blue"
}

Below is the code for that (code may not contain all device's string, I'm with other guys are maintaining the same code on GitHub so please take the latest code from there)

Objective-C : GitHub/DeviceUtil

Swift : GitHub/DeviceGuru

#include <sys/types.h>
#include <sys/sysctl.h>

- (NSString*)hardwareDescription {
    NSString *hardware = [self hardwareString];
    if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
    if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
    if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
    if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
    if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
    if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
    if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
    if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
    //there are lots of other strings too, checkout the github repo
    //link is given at the top of this answer

    if ([hardware isEqualToString:@"i386"]) return @"Simulator";
    if ([hardware isEqualToString:@"x86_64"]) return @"Simulator";

    return nil;
}

- (NSString*)hardwareString {
    size_t size = 100;
    char *hw_machine = malloc(size);
    int name[] = {CTL_HW,HW_MACHINE};
    sysctl(name, 2, hw_machine, &size, NULL, 0);
    NSString *hardware = [NSString stringWithUTF8String:hw_machine];
    free(hw_machine);
    return hardware;
}

Today, I would recommend using Task.CompletedTask to accomplish this.

Pre .net 4.6:

Using Task.FromResult(0) or Task.FromResult<object>(null) will incur less overhead than creating a Task with a no-op expression. When creating a Task with a result pre-determined, there is no scheduling overhead involved.

On tables of >1000000 rows I've found that these are both fast, with floor just slightly faster:

df['mydate'] = df.index.floor('d')

or

df['mydate'] = df.index.normalize()

If your index has timezones and you don't want those in the result, do:

df['mydate'] = df.index.tz_localize(None).floor('d')

df.index.date is many times slower; to_datetime() is even worse. Both have the further disadvantage that the results cannot be saved to an hdf store as it does not support type datetime.date.

Note that I've used the index as the date source here; if your source is another column, you would need to add .dt, e.g. df.mycol.dt.floor('d')

chunk2 <- function(x,n) split(x, cut(seq_along(x), n, labels = FALSE)) 

Why not just apply nav-link class?

<a href="#" class="nav-link">

Use below syntax to create schema class from XSD file.

C:\xsd C:\Test\test-Schema.xsd /classes /language:cs /out:C:\Test\

In openCV whenever you try to display an oversized image or image bigger than your display resolution you get the cropped display. It's a default behaviour.
In order to view the image in the window of your choice openCV encourages to use named window. Please refer to namedWindow documentation

The function namedWindow creates a window that can be used as a placeholder for images and trackbars. Created windows are referred to by their names.

cv.namedWindow(name, flags=CV_WINDOW_AUTOSIZE) where each window is related to image container by the name arg, make sure to use same name

eg:

import cv2
frame = cv2.imread('1.jpg')
cv2.namedWindow("Display 1")
cv2.resizeWindow("Display 1", 300, 300)
cv2.imshow("Display 1", frame)

Bit rate is a measure of the number of data bits (that's 0's and 1's) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation 'bps'.

Baud rate by definition means the number of times a signal in a communications channel changes state. For example, a 2400 baud rate means that the channel can change states up to 2400 times per second. When I say 'change state' I mean that it can change from 0 to 1 up to 2400 times per second. If you think about this, it's pretty much similar to the bit rate, which in the above example was 2400 bps.

Whether you can transmit 2400 zeros or ones in one second (bit rate), or change the state of a digital signal up to 2400 times per second (baud rate), it the same thing.

You could do

<body onload="window.print()">
...
</body>

From the SQL Server Management Studio you can right click on your database and select:

Tasks -> Generate Scripts

Then simply proceed through the wizard. Make sure to set 'Script Data' to TRUE when prompted to choose the script options.

SQL Server 2008 R2

Further reading:

• Robert Burke: SQL Server 2005 - Scripting your Database

var idList=new int[]{1, 2, 3, 4};
var friendsToUpdate = await Context.Friends.Where(f => 
    idList.Contains(f.Id).ToListAsync();

foreach(var item in previousEReceipts)
{
  item.msgSentBy = "1234";
}

You can use foreach to update each element that meets your condition.

Here is an example in a more generic way:

var itemsToUpdate = await Context.friends.Where(f => f.Id == <someCondition>).ToListAsync();

foreach(var item in itemsToUpdate)
{
   item.property = updatedValue;
}
Context.SaveChanges()

In general you will most probably use async methods with await for db queries.

Multiple Approch can be applied:

• Class Based Approch: use local state and define existing field with default value:

constructor(props) {
    super(props);
    this.state = {
      value:''
    }
  }
<input type='text'
                  name='firstName'
                  value={this.state.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• Using Hooks React > 16.8 in functional style components:

[value, setValue] = useState('');
<input type='text'
                  name='firstName'
                  value={value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />

• If Using propTypes and providing Default Value for propTypes in case of HOC component in functional style.

 HOC.propTypes = {
    value       : PropTypes.string
  }
  HOC.efaultProps = {
    value: ''
  }

function HOC (){

  return (<input type='text'
                  name='firstName'
                  value={this.props.value}
                  className="col-12"
                  onChange={this.onChange}
                  placeholder='Enter First name' />)

}

Regarding to the originally error message

cannot be resolved to absolute file path because it does not reside in the file system

The following code could be helpful, to find the solution for the path problem:

Paths.get("message.txt").toAbsolutePath().toString();

With this you can determine, where the application expects the missing file. You can execute this in the main method of your application.

You can specify the constraints and defaults in a CREATE TABLE AS SELECT, but the syntax is as follows

create table t1 (id number default 1 not null);
insert into t1 (id) values (2);

create table t2 (id default 1 not null)
as select * from t1;

That is, it won't inherit the constraints from the source table/select. Only the data type (length/precision/scale) is determined by the select.

var TableRowItem = React.createClass({
  render: function() {

    var td = function() {
        return this.props.columns.map(function(c, i) {
          return <td key={i}>{this.props.data[c]}</td>;
        }, this);
      }.bind(this);

    return (
      <tr>{ td(this.props.item) }</tr>
    )
  }
});

This will sove the problem.

Depends on what you run in that thread. If that's your code, then you can implement a stop condition (see other answers).

However, if what you want is to run someone else's code, then you should fork and start a process. Like this:

import multiprocessing
proc = multiprocessing.Process(target=your_proc_function, args=())
proc.start()

now, whenever you want to stop that process, send it a SIGTERM like this:

proc.terminate()
proc.join()

And it's not slow: fractions of a second. Enjoy :)

DateTime dt1 = this.dateTimePicker1.Value.Date;
DateTime dt2 = this.dateTimePicker2.Value.Date.AddMinutes(1440);
String query = "SELECT * FROM student WHERE sdate BETWEEN '" + dt1 + "' AND '" + dt2 + "'";

This post is old but may come up via searching.

Now you can use mysql.connector to retrive a dictionary as shown here: https://dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursordict.html

Here is the example on the mysql site:

cnx = mysql.connector.connect(database='world')
cursor = cnx.cursor(dictionary=True)
cursor.execute("SELECT * FROM country WHERE Continent = 'Europe'")

print("Countries in Europe:")
for row in cursor:
    print("* {Name}".format(Name=row['Name']))

You can simply use base64.urlsafe_b64decode(data) if you are trying to decode a web image. It will automatically take care of the padding.

If the program was written in C# you can get the source code in almost its original form using .NET Reflector. You won't be able to see comments and local variable names, but it is very readable.

If it was written C++ it's not so easy... even if you could decompile the code into valid C++ it is unlikely that it will resemble the original source because of inlined functions and optimizations which are hard to reverse.

Please note that by reverse engineering and modifying the source code you might breaking the terms of use of the programs unless you wrote them yourself or have permission from the author.

With plt.scatter, I can only think of one: to use a proxy artist:

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
fig1 = plt.figure(1)
ax1 = fig1.add_subplot(111)
x=ax1.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)

ccm=x.get_cmap()
circles=[Line2D(range(1), range(1), color='w', marker='o', markersize=10, markerfacecolor=item) for item in ccm((array([4,6,8])-4.0)/4)]
leg = plt.legend(circles, ['4','6','8'], loc = "center left", bbox_to_anchor = (1, 0.5), numpoints = 1)

And the result is:

I was running into a similar issue where the whole ../lib/utils directory couldn't be found when I tried executing Mocha via npm test. I tried the mentioned solutions here with no luck. Ultimately I ended up uninstalling and reinstalling the Mocha package that was a dependency in the npm project I was working in and it worked after that. So if anyone's having this issue with an npm package installed as a dependency, try uninstalling and reinstalling the package if you haven't already!

getCurrentItem(), doesn't actually give the right position for the first and the last page I fixed it adding this code:

public void CalcPostion() {    
    current = viewPager.getCurrentItem();

    if ((last == current) && (current != 1) && (current != 0)) {
        current = current + 1;
        viewPager.setCurrentItem(current);
    }
    if ((last == 1) && (current == 1)) {
        last = 0;
        current = 0;
    }
    display();
    last = current;
}

with open('target.txt','w') as out:
    line1 = raw_input("line 1: ")
    line2 = raw_input("line 2: ")
    line3 = raw_input("line 3: ")
    print("I'm going to write these to the file.")
    out.write('{}\n{}\n{}\n'.format(line1,line2,line3))

Try this:

return Redirect("http://www.website.com");

Try with this:

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):

SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X

Not for nothing, but you shouldn't just automatically use the latest library. If they release the newest library tomorrow and it breaks some of your scripts, you are SOL, but if you use the library you used to develop the scripts, you will ensure they will work.

There would be two ways to define constants - const and static final, with the exact same semantics. Furthermore static final describes the behaviour better than const

The answer from dbarnard has the formula to calculate the correct radius, but since you were looking for the templates, all the masks and overlays can be found in this directory:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/PrivateFrameworks/MobileIcons.framework

(path is for recent versions of XCode. For older version it will probably be inside /Developer/).

As others have noted, you should NOT mask them yourself, but you can use these to check how your icons will look once masked.

(credits for this finding goes to Neven Mrgan IIRC)

Make sure you are running the test as a superuser.

sudo nginx -t

Or the test wont have all the permissions needed to complete the test properly.

This is an example without using the onClick event. I simply pass a callback function to the child by props. With that callback the child call also send data back. I was inspired by the examples in the docs.

Small example (this is in a tsx files, so props and states must be declared fully, I deleted some logic out of the components, so it is less code).

*Update: Important is to bind this to the callback, otherwise the callback has the scope of the child and not the parent. Only problem: it is the "old" parent...

SymptomChoser is the parent:

interface SymptomChooserState {
  // true when a symptom was pressed can now add more detail
  isInDetailMode: boolean
  // since when user has this symptoms
  sinceDate: Date,
}

class SymptomChooser extends Component<{}, SymptomChooserState> {

  state = {
    isInDetailMode: false,
    sinceDate: new Date()
  }

  helloParent(symptom: Symptom) {
    console.log("This is parent of: ", symptom.props.name);
    // TODO enable detail mode
  }

  render() {
    return (
      <View>
        <Symptom name='Fieber' callback={this.helloParent.bind(this)} />
      </View>
    );
  }
}

Symptom is the child (in the props of the child I declared the callback function, in the function selectedSymptom the callback is called):

interface SymptomProps {
  // name of the symptom
  name: string,
  // callback to notify SymptomChooser about selected Symptom.
  callback: (symptom: Symptom) => void
}

class Symptom extends Component<SymptomProps, SymptomState>{

  state = {
    isSelected: false,
    severity: 0
  }

  selectedSymptom() {
    this.setState({ isSelected: true });
    this.props.callback(this);
  }

  render() {
    return (
      // symptom is not selected
      <Button
        style={[AppStyle.button]}
        onPress={this.selectedSymptom.bind(this)}>
        <Text style={[AppStyle.textButton]}>{this.props.name}</Text>
      </Button>
    );
  }
}

As per my understanding sys.stdout.flush() pushes out all the data that has been buffered to that point to a file object. While using stdout, data is stored in buffer memory (for some time or until the memory gets filled) before it gets written to terminal. Using flush() forces to empty the buffer and write to terminal even before buffer has empty space.

What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).

This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id on a OneToOne or ManyToOne. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn and also define a Basic Id mapping for the foreign key column.

Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?

You can obtain a similar result but using an Id on OneToOne or ManyToOne is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:

11.1.40 PrimaryKeyJoinColumn Annotation

The PrimaryKeyJoinColumn annotation specifies a primary key column that is used as a foreign key to join to another table.

The PrimaryKeyJoinColumn annotation is used to join the primary table of an entity subclass in the JOINED mapping strategy to the primary table of its superclass; it is used within a SecondaryTable annotation to join a secondary table to a primary table; and it may be used in a OneToOne mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity^[108].

...

If no PrimaryKeyJoinColumn annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass.

...

Example: Customer and ValuedCustomer subclass

@Entity
@Table(name="CUST")
@Inheritance(strategy=JOINED)
@DiscriminatorValue("CUST")
public class Customer { ... }

@Entity
@Table(name="VCUST")
@DiscriminatorValue("VCUST")
@PrimaryKeyJoinColumn(name="CUST_ID")
public class ValuedCustomer extends Customer { ... }

_{[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over PrimaryKeyJoinColumn for the OneToOne mapping case.}

This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?

The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.

For the record, support of Id on OneToOne and ManyToOne has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.

Just use substring: "apple".substring(3); will return le

yourbox{
   position:absolute;
   right:<x>px;
   top  :<x>px;
}

positions it in the right corner. Note, that the position is dependent of the first ancestor-element which is not static positioned!

EDIT:

I updated your fiddle.

You can try this

func getTime() -> (hour:Int, min:Int, sec:Int) {
        let currentDateTime = NSDate()
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components([.Hour,.Minute,.Second], fromDate: currentDateTime)
        let hour = components.hour
        let min = components.minute
        let sec = components.second
        return (hour,min,sec)
    }

Now call that method and receive the date with hour,min and second

    let currentTime = self.getTime()
    print("Hour: \(currentTime.hour) Min: \(currentTime.min) Sec: \(currentTime.sec))")

Use the string's constructor

basic_string(const charT* s,size_type n, const Allocator& a = Allocator());

EDIT:

OK, then if the C string length is not given explicitly, use the ctor:

basic_string(const charT* s, const Allocator& a = Allocator());

public class ListOfLists<T> : List<List<T>>
{
}


var myList = new ListOfLists<string>();

You should chain the replace() together instead of assigning the result and replacing again.

var strMessage1 = document.getElementById("element1") ;
strMessage1.innerHTML = strMessage1.innerHTML
                        .replace(/aaaaaa./g,'<a href=\"http://www.google.com/')
                        .replace(/.bbbbbb/g,'/world\">Helloworld</a>');

See DEMO.

I think it's quite dangerous to rely on the order of the values in a enum and to assume that the first is always the default. This would be good practice if you are concerned about protecting the default value.

enum E
{
    Foo = 0, Bar, Baz, Quux
}

Otherwise, all it takes is a careless refactor of the order and you've got a completely different default.

Just replace -H with -h. Check man grep for more details on options

find . -name '*.bar' -exec grep -hn FOO {} \;

Use a Bundle. Here's an example:

Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);

Bundle has put methods for lots of data types. See this

Then in your Fragment, retrieve the data (e.g. in onCreate() method) with:

Bundle bundle = this.getArguments();
if (bundle != null) {
        int myInt = bundle.getInt(key, defaultValue);
}

There is also W3Techs, which shows you much of that information.

Here are some Tips:

DELETE

• 200 (if you want send some additional data in the Response) or 204 (recommended).

• 202 Operation deleted has not been committed yet.

• If there's nothing to delete, use 204 or 404 (DELETE operation is idempotent, delete an already deleted item is operation successful, so you can return 204, but it's true that idempotent doesn't necessarily imply the same response)

Other errors:

• 400 Bad Request (Malformed syntax or a bad query is strange but possible).
• 401 Unauthorized Authentication failure
• 403 Forbidden: Authorization failure or invalid Application ID.
• 405 Not Allowed. Sure.
• 409 Resource Conflict can be possible in complex systems.
• And 501, 502 in case of errors.

PUT

If you're updating an element of a collection

• 200/204 with the same reasons as DELETE above.
• 202 if the operation has not been commited yet.

The referenced element doesn't exists:

• PUT can be 201 (if you created the element because that is your behaviour)

• 404 If you don't want to create elements via PUT.

• 400 Bad Request (Malformed syntax or a bad query more common than in case of DELETE).

• 401 Unauthorized

• 403 Forbidden: Authentication failure or invalid Application ID.

• 405 Not Allowed. Sure.

• 409 Resource Conflict can be possible in complex systems, as in DELETE.

• 422 Unprocessable entity It helps to distinguish between a "Bad request" (e.g. malformed XML/JSON) and invalid field values

• And 501, 502 in case of errors.

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

Apache POI 3.5 have added support to all the OOXML (docx, xlsx, etc.)
