If I remember correctly, there is a strict standard limit for the memory usage in V8 of around 1.7 GB, if you do not increase it manually.

In one of our products we followed this solution in our deploy script:

 node --max-old-space-size=4096 yourFile.js

There would also be a new space command but as I read here: a-tour-of-v8-garbage-collection the new space only collects the newly created short-term data and the old space contains all referenced data structures which should be in your case the best option.

Google maps requires an API key for new projects since june 2016. For more information take a look at the Google Developers Blog. Also more information in german you'll find at this blog post from the clickstorm Blog.

There are several decisions to make:

1. The first about resource path:

   • Model the image as a resource on its own:

     • Nested in user (/user/:id/image): the relationship between the user and the image is made implicitly

     • In the root path (/image):

       • The client is held responsible for establishing the relationship between the image and the user, or;

       • If a security context is being provided with the POST request used to create an image, the server can implicitly establish a relationship between the authenticated user and the image.

   • Embed the image as part of the user

2. The second decision is about how to represent the image resource:

   • As Base 64 encoded JSON payload
   • As a multipart payload

This would be my decision track:

• I usually favor design over performance unless there is a strong case for it. It makes the system more maintainable and can be more easily understood by integrators.
• So my first thought is to go for a Base64 representation of the image resource because it lets you keep everything JSON. If you chose this option you can model the resource path as you like.
  • If the relationship between user and image is 1 to 1 I'd favor to model the image as an attribute specially if both data sets are updated at the same time. In any other case you can freely choose to model the image either as an attribute, updating the it via PUT or PATCH, or as a separate resource.
• If you choose multipart payload I'd feel compelled to model the image as a resource on is own, so that other resources, in our case, the user resource, is not impacted by the decision of using a binary representation for the image.

Then comes the question: Is there any performance impact about choosing base64 vs multipart?. We could think that exchanging data in multipart format should be more efficient. But this article shows how little do both representations differ in terms of size.

My choice Base64:

• Consistent design decision
• Negligible performance impact
• As browsers understand data URIs (base64 encoded images), there is no need to transform these if the client is a browser
• I won't cast a vote on whether to have it as an attribute or standalone resource, it depends on your problem domain (which I don't know) and your personal preference.

This can occur on android too not just computers. Was browsing using Kiwi when the site I was on began to endlessly redirect so I cut net access to close it out and noticed my phone had DL'd something f.txt in my downloaded files.

Deleted it and didn't open.

Use re.sub

import re

regex = re.compile('[^a-zA-Z]')
#First parameter is the replacement, second parameter is your input string
regex.sub('', 'ab3d*E')
#Out: 'abdE'

Alternatively, if you only want to remove a certain set of characters (as an apostrophe might be okay in your input...)

regex = re.compile('[,\.!?]') #etc.

As far as I know, it's the main entry point to your node package (library) for npm. It's needed if your npm project becomes a node package (library) which can be installed via npm by others.

Let's say you have a library with a build/, dist/, or lib/ folder. In this folder, you got the following compiled file for your library:

-lib/
--bundle.js

Then in your package.json, you tell npm how to access the library (node package):

{
  "name": "my-library-name",
  "main": "lib/bundle.js",
  ...
}

After installing the node package with npm to your JS project, you can import functionalities from your bundled bundle.js file:

import { add, subtract } from 'my-library-name';

This holds also true when using Code Splitting (e.g. Webpack) for your library. For instance, this webpack.config.js makes use of code splitting the project into multiple bundles instead of one.

module.exports = {
  entry: {
    main: './src/index.js',
    add: './src/add.js',
    subtract: './src/subtract.js',
  },
  output: {
    path: `${__dirname}/lib`,
    filename: '[name].js',
    library: 'my-library-name',
    libraryTarget: 'umd',
  },
  ...
}

Still, you would define one main entry point to your library in your package.json:

{
  "name": "my-library-name",
  "main": "lib/main.js",
  ...
}

Then when using the library, you can import your files from your main entry point:

import { add, subtract } from 'my-library-name';

However, you can also bypass the main entry point from the package.json and import the code splitted bundles:

import add from 'my-library-name/lib/add';
import subtract from 'my-library-name/lib/subtract';

After all, the main property in your package.json only points to your main entry point file of your library.

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

I see a lot of examples of the Microsoft Dispose pattern which is really an anti-pattern. As many have pointed out the code in the question does not require IDisposable at all. But if you where going to implement it please don't use the Microsoft pattern. Better answer would be following the suggestions in this article:

https://www.codeproject.com/Articles/29534/IDisposable-What-Your-Mother-Never-Told-You-About

The only other thing that would likely be helpful is suppressing that code analysis warning... https://docs.microsoft.com/en-us/visualstudio/code-quality/in-source-suppression-overview?view=vs-2017

For the disabled buttons you can use the :disabled pseudo-element. It works for all the elements.

For browsers/devices supporting CSS2 only, you can use the [disabled] selector.

As with the image, don't put an image in the button. Use CSS background-image with background-position and background-repeat. That way, the image dragging will not occur.

Selection problem: here is a link to the specific question:

I suggest you to look at this highly rated blog post which manages to give a solution to the problem you're facing :

His code is based on the current Android APIs and should work in your case given that you are using a recent Android API.

Had been wrecking my head on symlinking node .. and nothing seemed to work...but finally what worked is setting the right permissions . This 'sudo chown -R $(whoami) /usr/local' did the work for me.

If you've already pushed things to a remote server (and you have other developers working off the same remote branch) the important thing to bear in mind is that you don't want to rewrite history

Don't use git reset --hard

You need to revert changes, otherwise any checkout that has the removed commits in its history will add them back to the remote repository the next time they push; and any other checkout will pull them in on the next pull thereafter.

If you have not pushed changes to a remote, you can use

git reset --hard <hash>

If you have pushed changes, but are sure nobody has pulled them you can use

git reset --hard
git push -f

If you have pushed changes, and someone has pulled them into their checkout you can still do it but the other team-member/checkout would need to collaborate:

(you) git reset --hard <hash>
(you) git push -f

(them) git fetch
(them) git reset --hard origin/branch

But generally speaking that's turning into a mess. So, reverting:

The commits to remove are the lastest

This is possibly the most common case, you've done something - you've pushed them out and then realized they shouldn't exist.

First you need to identify the commit to which you want to go back to, you can do that with:

git log

just look for the commit before your changes, and note the commit hash. you can limit the log to the most resent commits using the -n flag: git log -n 5

Then reset your branch to the state you want your other developers to see:

git revert  <hash of first borked commit>..HEAD

The final step is to create your own local branch reapplying your reverted changes:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Continue working in my-new-branch until you're done, then merge it in to your main development branch.

The commits to remove are intermingled with other commits

If the commits you want to revert are not all together, it's probably easiest to revert them individually. Again using git log find the commits you want to remove and then:

git revert <hash>
git revert <another hash>
..

Then, again, create your branch for continuing your work:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Then again, hack away and merge in when you're done.

You should end up with a commit history which looks like this on my-new-branch

2012-05-28 10:11 AD7six             o [my-new-branch] Revert "Revert "another mistake""
2012-05-28 10:11 AD7six             o Revert "Revert "committing a mistake""
2012-05-28 10:09 AD7six             o [master] Revert "committing a mistake"
2012-05-28 10:09 AD7six             o Revert "another mistake"
2012-05-28 10:08 AD7six             o another mistake
2012-05-28 10:08 AD7six             o committing a mistake
2012-05-28 10:05 Bob                I XYZ nearly works

Better way®

Especially that now that you're aware of the dangers of several developers working in the same branch, consider using feature branches always for your work. All that means is working in a branch until something is finished, and only then merge it to your main branch. Also consider using tools such as git-flow to automate branch creation in a consistent way.

use this syntax: alter table table_name modify column col_name varchar (10000);

You could try using the with binding that knockout offers: http://knockoutjs.com/documentation/with-binding.html The idea is to use apply bindings once, and whenever your data changes, just update your model.

Lets say you have a top level view model storeViewModel, your cart represented by cartViewModel, and a list of items in that cart - say cartItemsViewModel.

You would bind the top level model - the storeViewModel to the whole page. Then, you could separate the parts of your page that are responsible for cart or cart items.

Lets assume that the cartItemsViewModel has the following structure:

var actualCartItemsModel = { CartItems: [
  { ItemName: "FirstItem", Price: 12 }, 
  { ItemName: "SecondItem", Price: 10 }
] }

The cartItemsViewModel can be empty at the beginning.

The steps would look like this:

1. Define bindings in html. Separate the cartItemsViewModel binding.

     
       <div data-bind="with: cartItemsViewModel">
         <div data-bind="foreach: CartItems">
           <span data-bind="text: ItemName"></span>
           <span data-bind="text: Price"></span>
         </div>
       </div>
     
   

2. The store model comes from your server (or is created in any other way).

   var storeViewModel = ko.mapping.fromJS(modelFromServer)

3. Define empty models on your top level view model. Then a structure of that model can be updated with actual data.

     
       storeViewModel.cartItemsViewModel = ko.observable();
       storeViewModel.cartViewModel = ko.observable();
    
   

4. Bind the top level view model.

   ko.applyBindings(storeViewModel);

5. When the cartItemsViewModel object is available then assign it to the previously defined placeholder.

   storeViewModel.cartItemsViewModel(actualCartItemsModel);

If you would like to clear the cart items: storeViewModel.cartItemsViewModel(null);

Knockout will take care of html - i.e. it will appear when model is not empty and the contents of div (the one with the "with binding") will disappear.

This will search every column of every table in a specific database. Create the stored procedure on the database that you want to search in.

As stated in an article by Slicehost:

User setup

So let's start by adding the main user to the Apache user group:

sudo usermod -a -G www-data demo

That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.

You will need to log out and log back in again to enable the group change.

Check the groups now:

groups
...
# demo www-data

So now I am a member of two groups: My own (demo) and the Apache group (www-data).

Folder setup

Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).

Let's set that up:

sudo chgrp -R www-data /home/demo/public_html

As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.

If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.

Setgid

Good so far, but remember the command we just gave only affects existing folders. What about anything new?

We can set the ownership so anything new is also in the 'www-data' group.

The first command will change the permissions for the public_html directory to include the "setgid" bit:

sudo chmod 2750 /home/demo/public_html

That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.

If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:

sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads

The permissions only need to be set once as new files will automatically be assigned the correct ownership.

On express 3 you can use directly res.json({foo:bar})

res.json({ msgId: msg.fileName })

See the documentation

console.log() just takes whatever you pass to it and writes it to a console's log window. If you pass in an array, you'll be able to inspect the array's contents. Pass in an object, you can examine the object's attributes/methods. pass in a string, it'll log the string. Basically it's "document.write" but can intelligently take apart its arguments and write them out elsewhere.

It's useful to outputting occasional debugging information, but not particularly useful if you have a massive amount of debugging output.

To watch as a script's executing, you'd use a debugger instead, which allows you step through the code line-by-line. console.log's used when you need to display what some variable's contents were for later inspection, but do not want to interrupt execution.

I would combine node-http-proxy and express.

node-http-proxy will support a proxy inside your node.js web server via RoutingProxy (see the example called Proxy requests within another http server).

Inside your custom server logic you can do authentication using express. See the auth sample here for an example.

Combining those two examples should give you what you want.

I had a similar problem. Using size_t was not working. I tried the other one which worked for me. (as below)

for(int i = things.size()-1;i>=0;i--)
{
 //...
}

Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

Yea...having an additional step to update a table in which you can set the value in the inital insert is probably an extra, avoidable process. Do you have access to the original insert statement where you can actually just insert the part_description into the part_description_upper column using UPPER(part_description) value?

After thinking, you probably don't have access as you would have probably done that so should also give some options as well...

1) Depends on the need for this part_description_upper column, if just for "viewing" then can just use the returned part_description value and "ToUpper()" it (depending on programming language).

2) If want to avoid "realtime" processing, can just create a sql job to go through your values once a day during low traffic periods and update that column to the UPPER part_description value for any that are currently not set.

3) go with your trigger (and watch for recursion as others have mentioned)...

$( 'input[name="testGroup"]:radio' ).on('change', function(e) {_x000D_
     console.log(e.type);_x000D_
     return false;_x000D_
});

This syntax is a little more flexible to handle events. Not only can you observe "changes", but also other types of events can be controlled here too by using one single event handler. You can do this by passing the list of events as arguments to the first parameter. See jQuery On

Secondly, .change() is a shortcut for .on( "change", handler ). See here. I prefer using .on() rather than .change because I have more control over the events.

Lastly, I'm simply showing an alternative syntax to attach the event to the element.

Assuming SQL Server 2000, the following StackOverflow question should address your problem.

If using SQL Server 2005/2008, you can use the following code (taken from here):

select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable

Navigate to your flavor of .Net and CPU architecture directory using CMD or powershell

Enter this command: aspnet_regiis –r

As with everything that seems scarier at first than it was later, the best way to get over the initial fear is to immerse yourself into the discomfort of the unknown! It is at times like that which we learn the most, after all.

Unfortunately, there are limitations. While you're still learning to use a function, you shouldn't assume the role of a teacher, for example. I often read answers from those who seemingly don't know how to use realloc (i.e. the currently accepted answer!) telling others how to use it incorrectly, occasionally under the guise that they've omitted error handling, even though this is a common pitfall which needs mention. Here's an answer explaining how to use realloc correctly. Take note that the answer is storing the return value into a different variable in order to perform error checking.

Every time you call a function, and every time you use an array, you are using a pointer. The conversions are occurring implicitly, which if anything should be even scarier, as it's the things we don't see which often cause the most problems. For example, memory leaks...

Array operators are pointer operators. array[x] is really a shortcut for *(array + x), which can be broken down into: * and (array + x). It's most likely that the * is what confuses you. We can further eliminate the addition from the problem by assuming x to be 0, thus, array[0] becomes *array because adding 0 won't change the value...

... and thus we can see that *array is equivalent to array[0]. You can use one where you want to use the other, and vice versa. Array operators are pointer operators.

malloc, realloc and friends don't invent the concept of a pointer which you've been using all along; they merely use this to implement some other feature, which is a different form of storage duration, most suitable when you desire drastic, dynamic changes in size.

It is a shame that the currently accepted answer also goes against the grain of some other very well-founded advice on StackOverflow, and at the same time, misses an opportunity to introduce a little-known feature which shines for exactly this usecase: flexible array members! That's actually a pretty broken answer... :(

When you define your struct, declare your array at the end of the structure, without any upper bound. For example:

struct int_list {
    size_t size;
    int value[];
};

This will allow you to unite your array of int into the same allocation as your count, and having them bound like this can be very handy!

sizeof (struct int_list) will act as though value has a size of 0, so it'll tell you the size of the structure with an empty list. You still need to add to the size passed to realloc to specify the size of your list.

Another handy tip is to remember that realloc(NULL, x) is equivalent to malloc(x), and we can use this to simplify our code. For example:

int push_back(struct int_list **fubar, int value) {
    size_t x = *fubar ? fubar[0]->size : 0
         , y = x + 1;

    if ((x & y) == 0) {
        void *temp = realloc(*fubar, sizeof **fubar
                                   + (x + y) * sizeof fubar[0]->value[0]);
        if (!temp) { return 1; }
        *fubar = temp; // or, if you like, `fubar[0] = temp;`
    }

    fubar[0]->value[x] = value;
    fubar[0]->size = y;
    return 0;
}

struct int_list *array = NULL;

The reason I chose to use struct int_list ** as the first argument may not seem immediately obvious, but if you think about the second argument, any changes made to value from within push_back would not be visible to the function we're calling from, right? The same goes for the first argument, and we need to be able to modify our array, not just here but possibly also in any other function/s we pass it to...

array starts off pointing at nothing; it is an empty list. Initialising it is the same as adding to it. For example:

struct int_list *array = NULL;
if (!push_back(&array, 42)) {
    // success!
}

P.S. Remember to free(array); when you're done with it!

For myself, I would assume unsigned int is platform specific. Integer could be 8 bits, 16 bits, 32 bits or even 64 bits.

DWORD in the other hand, specifies its own size, which is Double Word. Word are 16 bits so DWORD will be known as 32 bit across all platform

Generally you can't have constant time look up and log time deletions/insertions, but if you're happy with log time look ups then you can use a SortedList.

Not sure if you'll trust my coding but I recently wrote a SortedList implementation in Java, which you can download from http://www.scottlogic.co.uk/2010/12/sorted_lists_in_java/. This implementation allows you to look up the i-th element of the list in log time.

Normally, you run IE 32 bit.
However, on 64-bit versions of Windows, there is a separate link in the Start Menu to Internet Explorer (64 bit). There's no real reason to use it, though.

In Help, About, the 64-bit version of IE will say 64-bit Edition (just after the full version string).

The 32-bit and 64-bit versions of IE have separate addons lists (because 32-bit addons cannot be loaded in 64-bit IE, and vice-versa), so you should make sure that Java appears on both lists.

In general, you can tell whether a process is 32-bit or 64-bit by right-clicking the application in Task Manager and clicking Go To Process. 32-bit processes will end with *32.

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

I use UUID() to create a unique value.

example:

insert into Companies (CompanyID, CompanyName) Values(UUID(), "TestUUID");

I knew these answers were right , but my services.msc was not showing the services, however this did the trick:

sc stop "MsDepSvc" 
sc config "MsDepSvc" start= disabled 

IoC Containers are also good for loading deeply nested class dependencies. For example if you had the following code using Depedency Injection.

public void GetPresenter()
{
    var presenter = new CustomerPresenter(new CustomerService(new CustomerRepository(new DB())));
}

class CustomerPresenter
{
    private readonly ICustomerService service;
    public CustomerPresenter(ICustomerService service)
    {
        this.service = service;
    }
}

class CustomerService
{
    private readonly IRespository<Customer> repository;
    public CustomerService(IRespository<Customer> repository)
    {
        this.repository = repository;
    }
}

class CustomerRepository : IRespository<Customer>
{
    private readonly DB db;
    public CustomerRepository(DB db)
    {
        this.db = db;
    }
}

class DB { }

If you had all of these dependencies loaded into and IoC container you could Resolve the CustomerService and the all the child dependencies will automatically get resolved.

For example:

public static IoC
{
   private IUnityContainer _container;
   static IoC()
   {
       InitializeIoC();
   }

   static void InitializeIoC()
   {
      _container = new UnityContainer();
      _container.RegisterType<ICustomerService, CustomerService>();
      _container.RegisterType<IRepository<Customer>, CustomerRepository>();
   }

   static T Resolve<T>()
   {
      return _container.Resolve<T>();
   }
}

public void GetPresenter()
{
   var presenter = IoC.Resolve<CustomerPresenter>();
   // presenter is loaded and all of its nested child dependencies 
   // are automatically injected
   // -
   // Also, note that only the Interfaces need to be registered
   // the concrete types like DB and CustomerPresenter will automatically 
   // resolve.
}

i had to use a csv parser about 5 years ago. seems there are at least two csv standards: http://en.wikipedia.org/wiki/Comma-separated_values and what microsoft does in excel.

i found this libaray which eats both: http://ostermiller.org/utils/CSV.html, but afaik, it has no way of inferring what data type the columns were.

I have a varargs-related fear, too:

If the caller passes in an explicit array to the method (as opposed to multiple parameters), you will receive a shared reference to that array.

If you need to store this array internally, you might want to clone it first to avoid the caller being able to change it later.

 Object[] args = new Object[] { 1, 2, 3} ;

 varArgMethod(args);  // not varArgMethod(1,2,3);

 args[2] = "something else";  // this could have unexpected side-effects

While this is not really different from passing in any kind of object whose state might change later, since the array is usually (in case of a call with multiple arguments instead of an array) a fresh one created by the compiler internally that you can safely use, this is certainly unexpected behaviour.

Note that you don't need semicolons in batch files. And the reason why you need to use call is that mvn itself is a batch file and batch files need to call each other with call, otherwise control does not return to the caller.

If you work with developers, often get a sliver of code that is formatted as one long line of code, then sql pretty printer add-on for SQL Server management Studio may helps a lot with more than 60+ formatter options. http://www.dpriver.com/sqlpp/ssmsaddin.html

You can try use simple command line. bcdedit is what you need, just run cmd as administrator and type bcdedit or bcdedit \v, this doesn't work on XP, but hope it is not an issue.

Anyway for XP you can take a look into boot.ini file.

FYI: it looks like you might have an infinite loop in your example...

if cnt > 0 and len(aStr) > 1:
    while cnt > 0:                  
        aStr = aStr[1:]+aStr[0]
        cnt += 1

• a condition of entering the loop is that cnt is greater than 0
• the loop continues to run as long as cnt is greater than 0
• each iteration of the loop increments cnt by 1

The net result is that cnt will always be greater than 0 and the loop will never exit.

There have no differences between Integer.toString(5) and String.valueOf(5);

because String.valueOf returns:

public static String valueOf(int i) {
    return Integer.toString(i);
}
public static String valueOf(float f) {
    return Float.toString(f);
}

etc..

Don't define variables in headers. Put declarations in header and definitions in one of the .c files.

In config.h

extern const char *names[];

In some .c file:

const char *names[] =
    {
        "brian", "stefan", "steve"
    };

If you put a definition of a global variable in a header file, then this definition will go to every .c file that includes this header, and you will get multiple definition error because a varible may be declared multiple times but can be defined only once.

For a Windows machine start the mongod process by specifying the dbpath:

mongod --dbpath \mongodb\data

If (when the file doesn't exist) you want to create it as empty, the simplest approach is

with open(thepath, 'a'): pass

(in Python 2.6 or better; in 2.5, this requires an "import from the future" at the top of your module).

If, on the other hand, you want to leave the file alone if it exists, but put specific non-empty contents there otherwise, then more complicated approaches based on if os.path.isfile(thepath):/else statement blocks are probably more suitable.

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_
</div>

You could try adding a bool so the algorithm would know when the button was activated. When it's clicked, the bool checks true, the new form shows and the last gets closed.

It's important to know that forms consume some ram (at least a little bit), so it's a good idea to close those you're not gonna use, instead of just hiding it. Makes the difference in big projects.

moveBus() is getting called before initialize(). Try putting that line at the end of your initialize() function. Also Lat/Lon 0,0 is off the map (it's coordinates, not pixels), so you can't see it when it moves. Try 54,54. If you want the center of the map to move to the new location, use panTo().

            mapTypeId: google.maps.MapTypeId.ROADMAP
            },
        map = new google.maps.Map( document.getElementById( 'map-canvas' ), myOptions ),
        marker = new google.maps.Marker( {position: myLatLng, map: map} );

    marker.setPosition( new google.maps.LatLng( 0, 0 ) );

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

I don't have enough points to comment on an answer, but I wanted to say that mikec's answer worked for me except that I had to change it to return !isScrollable like so:

mScroller.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
      return !isScrollable;
    }
});

I understand the original poster was looking for a simple solution, but unfortunately there really is no simple solution.

Nevertheless, I've recently created an open-source freeware clipping library (written in Delphi, C++ and C#) which clips all kinds of polygons (including self-intersecting ones). This library is pretty simple to use: http://sourceforge.net/projects/polyclipping/ .

If you are using reflection, you can get the Method object and then:

method.getDeclaringClass().getName()

To get the Method itself, you can probably use:

Class<?> c = Class.forName("class name");
Method  method = c.getDeclaredMethod ("method name", parameterTypes)

Elegant ES6 function to format a date into hh:mm:ss:

const leadingZero = (num) => `0${num}`.slice(-2);

const formatTime = (date) =>
  [date.getHours(), date.getMinutes(), date.getSeconds()]
  .map(leadingZero)
  .join(':');

To check if a specific tab page is the currently selected page of a tab control is easy; just use the SelectedTab property of the tab control:

if (tabControl1.SelectedTab == someTabPage)
{
// Do stuff here...
}

This is more useful if the code is executed based on some event other than the tab page being selected (in which case SelectedIndexChanged would be a better choice).

For example I have an application that uses a timer to regularly poll stuff over TCP/IP connection, but to avoid unnecessary TCP/IP traffic I only poll things that update GUI controls in the currently selected tab page.

I just came across this old post. Nothing listed above actually worked for me. I tested the script below, and it worked fine on my system. Sharing here, for the benefit of others who come here after me.

Use the $expr operator which allows the use of aggregation expressions within the query language. This will give you the power to use the Date Aggregation Operators in your query as follows:

month = 11
db.mydatabase.mycollection.find({ 
    "$expr": { 
        "$eq": [ { "$month": "$date" }, month ] 
    } 
})

or

day = 17
db.mydatabase.mycollection.find({ 
    "$expr": { 
        "$eq": [ { "$dayOfMonth": "$date" }, day ] 
    } 
})

You could also run an aggregate operation with the aggregate() function that takes in a $redact pipeline:

month = 11
db.mydatabase.mycollection.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$eq": [ { "$month": "$date" }, month ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

For the other request

day = 17
db.mydatabase.mycollection.aggregate([
    {
        "$redact": {
            "$cond": [
                { "$eq": [ { "$dayOfMonth": "$date" }, day ] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

Using OR

month = 11
day = 17
db.mydatabase.mycollection.aggregate([
    {
        "$redact": {
            "$cond": [
                { 
                    "$or": [ 
                        { "$eq": [ { "$month": "$date" }, month ] },
                        { "$eq": [ { "$dayOfMonth": "$date" }, day ] }
                    ] 
                },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

Using AND

var month = 11,
    day = 17;
db.collection.aggregate([
    {
        "$redact": {
            "$cond": [
                { 
                    "$and": [ 
                        { "$eq": [ { "$month": "$createdAt" }, month ] },
                        { "$eq": [ { "$dayOfMonth": "$createdAt" }, day ] }
                    ] 
                },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    }
])

The $redact operator incorporates the functionality of $project and $match pipeline and will return all documents match the condition using $$KEEP and discard from the pipeline those that don't match using the $$PRUNE variable.

ps axuwww | grep java | grep -v grep

The above will

• show you all processes with long lines (arg: www)
• filter (grep) only lines what contain the word java, and
• filter out the line "grep java" :)

(btw, this example is not the effective one, but simple to remember) ;)

you can pipe the above to another commands, for example:

ps axuwww | grep java | grep -v grep | sed '.....'  | while read something
do
    something_another $something
done

etc...

Get-Content has bad performance; it tries to read the file into memory all at once.

C# (.NET) file reader reads each line one by one

Best Performace

foreach($line in [System.IO.File]::ReadLines("C:\path\to\file.txt"))
{
       $line
}

Or slightly less performant

[System.IO.File]::ReadLines("C:\path\to\file.txt") | ForEach-Object {
       $_
}

The foreach statement will likely be slightly faster than ForEach-Object (see comments below for more information).

Thanks to Evan's code sample, I was able to modify it more and get it more specific to tables starting with, specific column names AND handle specifics for constraints too. I ran that code and then copied the [CODE] column and executed it without issue.

General way:

with open('csvfile.csv','wb') as file:
    for line in text:
        file.write(line)
        file.write('\n')

OR

Using CSV writer :

with open(<path to output_csv>, "wb") as csv_file:
        writer = csv.writer(csv_file, delimiter=',')
        for line in data:
            writer.writerow(line)

Simplest way:

f = open('csvfile.csv','w')
f.write('hi there\n') #Give your csv text here.
## Python will convert \n to os.linesep
f.close()

MongoDB will find only one matching document which matches the query criteria when you are issuing an update command, whichever document matches first happens to be get updated, even if there are more documents which matches the criteria will get ignored.

so to overcome this we can specify "MULTI" option in your update statement, meaning update all those documnets which matches the query criteria. scan for all the documnets in collection finding those which matches the criteria and update :

db.test.update({"foo":"bar"},{"$set":{"test":"success!"}}, {multi:true} )

By default git revert refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD is in fact a merge commit.

If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.

Often this will be parent number one, for example if you were on master and did git merge unwanted and then decided to revert the merge of unwanted. The first parent would be your pre-merge master branch and the second parent would be the tip of unwanted.

In this case you could do:

git revert -m 1 HEAD

Use the overflow-y: scroll property on the element that contains the elements.

The overflow-y property specifies whether to clip the content, add a scroll bar, or display overflow content of a block-level element, when it overflows at the top and bottom edges.

Sometimes it is interesting to place a height for the element next to the overflow-y property, as in the example below:

<ul class="nav nav-pills nav-stacked" style="height: 250px; overflow-y: scroll;">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#">Disabled</a>
  </li>
</ul>

use the "unlink" command and make sure not to have the / at the end

$ unlink mySymLink

unlink() deletes a name from the file system. If that name was the last link to a file and no processes have the file open the file is deleted and the space it was using is made available for reuse. If the name was the last link to a file but any processes still have the file open the file will remain in existence until the last file descriptor referring to it is closed.

I think this may be problematic if I'm reading it correctly.

If the name referred to a symbolic link the link is removed.

If the name referred to a socket, fifo or device the name for it is removed but processes which have the object open may continue to use it.

https://linux.die.net/man/2/unlink

You can get that error if you have an object with the same name as the schema. For example:

create sequence s2;

begin
  s2.a;
end;
/

ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

When you refer to S2.MY_FUNC2 the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2 there is no confusion, so it works.

The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.

It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.

select owner, object_type, object_name
from all_objects
where object_name = 'S2';

There is no absolute answer to your question, because technology is always bound to be implementation-specific. I am assuming you are communicating in UDP because incoming buffer size does not bring problem to TCP communication.

According to RFC 768, the packet size (header-inclusive) for UDP can range from 8 to 65 515 bytes. So the fail-proof size for incoming buffer is 65 507 bytes (~64KB)

However, not all large packets can be properly routed by network devices, refer to existing discussion for more information:

What is the optimal size of a UDP packet for maximum throughput?
What is the largest Safe UDP Packet Size on the Internet

you can use prepacked function

function unzip_file($file, $destination){
    // create object
    $zip = new ZipArchive() ;
    // open archive
    if ($zip->open($file) !== TRUE) {
        return false;
    }
    // extract contents to destination directory
    $zip->extractTo($destination);
    // close archive
    $zip->close();
        return true;
}

How to use it.

if(unzip_file($file["name"],'uploads/')){
echo 'zip archive extracted successfully';
}else{
  echo 'zip archive extraction failed';
}

The first one is invalid syntax. You cannot have object properties inside a plain array. The second one is right although it is not strict JSON. It's a relaxed form of JSON wherein quotes in string keys are omitted.

This tutorial by Patrick Hunlock, may help to learn about JSON and this site may help to validate JSON.

If you want to set it to LF as default, you can go to File->Preferences->Settings and under user settings you can paste this line in below your other user settings.

"files.eol": "\n"

For example.

"git.confirmSync": false,
"window.zoomLevel": -1,
"workbench.activityBar.visible": true,
"editor.wordWrap": true,
"workbench.iconTheme": "vscode-icons",
"window.menuBarVisibility": "default",
"vsicons.projectDetection.autoReload": true,
"files.eol": "\n"

If you want to pass the Dictionary keys collection into one method argument.

List<string> lstKeys = Dict.Keys;
Methodname(lstKeys);
-------------------
void MethodName(List<String> lstkeys)
{
    `enter code here`
    //Do ur task
}

Looking at the select2 docs you use the below to get/set the value.

$("#select").select2("val"); //get the value
$("#select").select2("val", "CA"); //set the value

@PanPipes has pointed out that this has changed for 4.x (go toss him an upvote below). val is now called directly

$("#select").val("CA");

So within the loadComplete of the jqGrid you can get whatever value you are looking for then set the selectbox value.

Notice from the docs

Notice that in order to use this method you must define the initSelection function in the options so Select2 knows how to transform the id of the object you pass in val() to the full object it needs to render selection. If you are attaching to a select element this function is already provided for you.

parent.children is not an array. It is HTMLCollection and it does not have forEach method. You can convert it to the array first. For example in ES6:

Array.from(parent.children).forEach(child => {
    console.log(child)
});

or using spread operator:

[...parent.children].forEach(function (child) {
    console.log(child)
});

1. Go to [project]/.git directory.
2. Open for edit 'config' file.
3. In '[remote "origin"]' section find 'url' property and replace your old password with new one.
4. Press Ctrl+T in Intellij IDEA to update project.

If you want the content string and this string does not have parameters you can use

    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null){
        System.out.println(line);
    }

If you code C or C++ language. I think we are lucky because we could use a file to input. It is so convenient and clear. I often do that. This is argument to implement it :

{
freopen("inputfile", "r", stdin);
}

Notice that inputfile must locate at same directory with source code file, r is stand for read.

You can try this modal:https://github.com/xue2han/react-dynamic-modal It is stateless and can be rendered only when needed.So it is very easy to use.Just like this:

    class MyModal extends Component{
       render(){
          const { text } = this.props;
          return (
             <Modal
                onRequestClose={this.props.onRequestClose}
                openTimeoutMS={150}
                closeTimeoutMS={150}
                style={customStyle}>
                <h1>What you input : {text}</h1>
                <button onClick={ModalManager.close}>Close Modal</button>
             </Modal>
          );
       }
    }

    class App extends Component{
        openModal(){
           const text = this.refs.input.value;
           ModalManager.open(<MyModal text={text} onRequestClose={() => true}/>);
        }
        render(){
           return (
              <div>
                <div><input type="text" placeholder="input something" ref="input" /></div>
                <div><button type="button" onClick={this.openModal.bind(this)}>Open Modal </button> </div>
              </div>
           );
        }
    }

    ReactDOM.render(<App />,document.getElementById('main'));

I agree with Mark. I set the output to text mode and then sp_HelpText 'sproc'. I have this binded to Crtl-F1 to make it easy.

Matt's answer is the right one for older Pythons and Kevin's the right answer for newer ones.

If you wish not to copy the function for silentremove, this functionality is exposed in path.py as remove_p:

from path import Path
Path(filename).remove_p()

It's probably the file path to your file. If you don't know the exact location of the file you want to use, try to find your file in Finder, then drag the file into Terminal window

mysql> SOURCE dragfilePathHere 

In my system its the \ key. it's used for commands so that you can combine it with other chars.

This is already been answered right but i think i should give my opinion too. Like cozen says this is a border, and for it to work you must specify the classes to format this in the same way that bootstrap specifies it. So, you can do this

.tooltip .tooltip-inner {background-color: #00a8c4; color: black;} 
.tooltip.top .tooltip-arrow {border-top-color: #00a8c4;}

or you can do the next one, just for the tooltip-arrow but you must add the !important, so that it overwrites the bootstrap css

.tooltip-arrow {border-top-color: #00a8c4!important;}

No need for jQuery. And it isn't necessary to open a new window. Protocols which doesn't return HTTP data to the browser (mailto:, irc://, magnet:, ftp:// (<- it depends how it is implemented, normally the browser has an FTP client built in)) can be queried in the same window without losing the current content. In your case:

function redirect()
{
    window.location.href = "mailto:[email protected]";
}
<body onload="javascript: redirect();">

Or just directly

<body onload="javascript: window.location.href='mailto:[email protected]';">

Put the javascript part and the end right before the closing </body> then it should work.

http://jsfiddle.net/Q3Zy3/1/

  <img onclick="exportToForm('1.6','55','10','50','1');" src="China-Flag-256.png"/>
  <button onclick="exportToForm('1.6','55','10','50','1');" style="background-color: #00FFFF">Export</button>

  <script type="text/javascript">
      function exportToForm(a,b,c,d,e) {
      alert(a + b);
      window.external.values(a.value, b.value, c.value, d.value, e.value);
  }
</script>

If using virtualenv, look for the build directory under your environments root.

Turning PAE/NX on/off didn't work for me. I just needed to turn on virtualization on my computer. I was working on a HP Compaq 8200 and followed the steps below to turn on virtualization. If you are working on a different computer, you probably just need to look up how to turn on virtualization on your pc. The steps below for HP Compaq 8200 (or similar) is copied verbatim from the comment posted by the user qqdmax5 on Hp discussion board here.

To run Oracle VM Virtual Box / VMware machines on 64-bit host there is a need to enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).

Usually these setting are disabled on the level of BIOS.

To enable VTx and VTd you have to change corresponding settings in the BIOS.

Here is an example how to do it for HP Compaq 8200 or similar PC:

1. Start the machine.
2. Press F10 to enter BIOS.
3. Security-> System Security
4. Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd).
5. Save and restart the machine.

There is also some discussion on this on askubuntu.

Transition is more like an animation.

div.sicon a {
    background:-moz-radial-gradient(left, #ffffff 24%, #cba334 88%);
    transition: background 0.5s linear;
    -moz-transition: background 0.5s linear; /* Firefox 4 */
    -webkit-transition: background 0.5s linear; /* Safari and Chrome */
    -o-transition: background 0.5s linear; /* Opera */
    -ms-transition: background 0.5s linear; /* Explorer 10 */
}

So you need to invoke that animation with an action.

div.sicon a:hover {
    background:-moz-radial-gradient(left, #cba334 24%, #ffffff 88%);
}

Also check for browser support and if you still have some problem with whatever you're trying to do! Check css-overrides in your stylesheet and also check out for behavior: ***.htc css hacks.. there may be something overriding your transition!

You should check this out: http://www.w3schools.com/css/css3_transitions.asp

Just have your view controller register for the UIApplicationWillEnterForegroundNotification notification and react accordingly.

Your method can be called and the arraylist can be stored like this

YourClassName class = new YourClassName();
Arraylist<Integer> numbers = class.numbers(); 

This also allows the arraylist to be manipulated further in this class

To do this for oracle sql, the syntax would be:

,SUBSTR(col,INSTR(col,'-',1,2)+1) AS new_field

for this example, I look for the second '-' and take the substring to the end

I was getting this problem and it turned out I had included my controller both in ui.router and in the html template as in

.config(['$stateProvider',
  function($stateProvider) {
    $stateProvider.state('dashboard', {
      url: '/dashboard',
      templateUrl: 'dashboard/views/index.html',
      controller: 'DashboardController'
    });
  }
]);

and

<section data-ng-controller="DashboardController">

You can get the first of the month, by calculating the last_day of the month before and add one day. It is awkward, but I think it is better than formatting a date as string and use that for calculation.

select 
  *
from
  yourtable t
where
  /* Greater or equal to the start of last month */
  t.date >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) and
  /* Smaller or equal than one month ago */
  t.date <= DATE_SUB(NOW(), INTERVAL 1 MONTH)

In my case the issue was that my default kit's Qt version was None.

Go to Tools -> Options... -> Build & Run -> Kits tab, click on the kit you want to make as default and you'll see a list of fields beneath, one of which is Qt version. If it's None, change it to one of the versions available to you in the Qt versions tab which is just next to the Kits tab.

In my case first i connected my pc and mobile on the same network, you can ping your mobile from pc to test the connection.

I running my project with GGTS(Groovy/Grails Tool Suite) locally then accessing website from mobile using PC IP address and it's work very well.

PS. running from local it would give url like (http://localhost:8080/projectname) you should replace localhost with PC IP address if you are trying to access your local website from mobile

iframe is the tag which you can use for call other html pages into your web page

If you're currently on the branch you want to rename:

git branch -m new_name 

Or else:

git branch -m old_name new_name 

You can check with:

git branch -a

As you can see, only the local name changed Now, to change the name also in the remote you must do:

git push origin :old_name

This removes the branch, then upload it with the new name:

git push origin new_name

You might be importing Application instead of Module. Well you can change it in module's gradle also.

Change

apply plugin: 'com.android.application'

to

apply plugin: 'com.android.library'

You also need to remove applicationId from the gradle.

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

Actually, you should use several tools to get a bulletproof approach:

DIR_PATH=`readlink -f "${the_stuff_you_test}"` # Get rid of symlinks and get abs path
if [[ -d "${DIR_PATH}" ]] ; Then # Now you're testing
    echo "It's a dir";
fi

There isn't any need to worry about spaces and special characters as long as you use "${}".

Note that [[]] is not as portable as [], but since most people work with modern versions of Bash (since after all, most people don't even work with command line :-p), the benefit is greater than the trouble.

How about this?

CASE WHEN ProductAlternateKey is NOT NULL THEN
CONVERT(NVARCHAR(25), LTRIM(RTRIM(ProductAlternateKey))) 
FROM DimProducts
where ProductAlternateKey  like '46783815%'

If you're iterating over an object instead of an array, you'll need to access the properties using:

$id = $blog->id;
$title = $blog->title;
$content = $blog->content;

That, or change your object to an array.

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance application

H264 is now enshrined in MPEG4 as part 10 also known as AVC

Refer to: http://www.velleman.eu/downloads/3/h264_vs_mpeg4_en.pdf

Hope this helps.

If you are looking for all entries in the 1d array a smaller than their neighbors, you can try

numpy.r_[True, a[1:] < a[:-1]] & numpy.r_[a[:-1] < a[1:], True]

You could also smooth your array before this step using numpy.convolve().

I don't think there is a dedicated function for this.

Go to %ORACLE_HOME%\inventory\ContentsXML folder and open comps.xml file

Look for <DEP_LIST> on ~second screen.

Where did it come from scrollBottom this is not a valid property it should be scrollTop and this can be positive(+) or negative(-) values to scroll down(+) and up(-), so you can change:

scrollBottom 

to this scrollTop:

$("#upClick").on("click", function () {
    scrolled = scrolled - 300;

    $(".cover").animate({
        scrollTop: scrolled
    });//^^^^^^^^------------------------------this one
});

A workaround you can do is not use static classes but hide the constructor so the classes static members are the only thing accessible outside the class. The result is an inheritable "static" class essentially:

public class TestClass<T>
{
    protected TestClass()
    { }

    public static T Add(T x, T y)
    {
        return (dynamic)x + (dynamic)y;
    }
}

public class TestClass : TestClass<double>
{
    // Inherited classes will also need to have protected constructors to prevent people from creating instances of them.
    protected TestClass()
    { }
}

TestClass.Add(3.0, 4.0)
TestClass<int>.Add(3, 4)

// Creating a class instance is not allowed because the constructors are inaccessible.
// new TestClass();
// new TestClass<int>();

Unfortunately because of the "by-design" language limitation we can't do:

public static class TestClass<T>
{
    public static T Add(T x, T y)
    {
        return (dynamic)x + (dynamic)y;
    }
}

public static class TestClass : TestClass<double>
{
}

If you facing this issue at the workplace. This might be the solution for you.

pip install -U <package_name> --user --proxy=<your proxy>

You are getting an authentication error because the username and password in your config file is setup wrong.

Change this:

'username' => env('[email protected]'),
'password' => env('MyPassword'),

To this:

'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),

The env method checks your .env file. In your .env file you call these MAIL_USERNAME, so that's what you need to pass to the env method.

One troubleshooting tip: add dd(Config::get('mail')); so that you can see the actual generated config. This will help you spot issues like this, and know exactly what information Laravel is going to try and use. So you may want to stop that in your test route temporarily to examine what you have:

Route::get('test', function()
{
    dd(Config::get('mail'));
});

To install an apk on one of your emulators:

First get the list of devices:

-> adb devices
List of devices attached
25sdfsfb3801745eg        device
emulator-0954   device

Then install the apk on your emulator with the -s flag:

-> adb -s "25sdfsfb3801745eg" install "C:\Users\joel.joel\Downloads\release.apk"
Performing Streamed Install
Success

Ps.: the order here matters, so -s <id> has to come before install command, otherwise it won't work.

Hope this helps someone!

This is an old question, but here's another way to do it.

You can modify the R code itself instead of the chunk options, by wrapping the source call in suppressPackageStartupMessages(), suppressMessages(), and/or suppressWarnings(). E.g:

```{r echo=FALSE}
suppressWarnings(suppressMessages(suppressPackageStartupMessages({
source("C:/Rscripts/source.R")
})
```

You can also put those functions around your library() calls inside the "source.R" script.

you should use go modules now, if you are not following How to write go code

With go module you don't have to put the code in the $GOPATH/src. it can live in any other location as well.

You can move the code to different directory like /employee, To make it work Just under employee directory initialise the go module

go mod init example.com/employee

The new, modern way to do this is to calculate the vertical height by subtracting the height of both the header and the footer from the vertical-height of the viewport.

//CSS
header { 
  height: 50px;
}
footer { 
  height: 50px;
}
#content { 
  height: calc(100vh - 50px - 50px);
}

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

List can be instantiated by any class implementing the interface.By this way,Java provides us polymorphic behaviour.See the example below:

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

Instead of instantiating an ArrayList directly,I am using a List to refer to ArrayList object so that we are using only the List interface methods and do not care about its actual implementation.

Examples of classes implementing List are ArrayList,LinkedList,Vector.You probably want to create a List depending upon your requirements.

Example:- a LinkedList is more useful when you hve to do a number of inertion or deletions .Arraylist is more performance intensive as it is backed by a fixed size array and array contents have to be changed by moving or regrowing the array.

Again,using a List we can simply change our object instantiation without changing any code further in your programs.

Suppose we are using ArrayList<String> value = new ArrayList<String>();

we may use a specific method of ArrrayList and out code will not be robust

By using List<String> value = new ArrayList<String>();

we are making sure we are using only List interface methods..and if we want to change it to a LinkedList we simply have to change the code :

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

------ your code uses List interface methods.....

value = new LinkedList<String>(); 

-----your code still uses List interface methods and we do not have to change anything---- and we dont have to change anything in our code further

By the way a LinkedList also works a Deque which obviously also you cannot instantiate as it is also an interface

php -r 'parse_str($argv[2],$_GET);include $argv[1];' index.php 'a=1&b=2'

You could make the first part as an alias:

alias php-get='php -r '\''parse_str($argv[2],$_GET);include $argv[1];'\'

then simply use:

php-get some_script.php 'a=1&b=2&c=3'

This can be solved 100% entirely with HTML alone. Just set the href attribute to "data:(mimetypeheader),(url)". For instance...

<a
    href="data:video/mp4,http://www.example.com/video.mp4"
    target="_blank"
    download="video.mp4"
>Download Video</a>

Working example: JSFiddle Demo.

Because we use a Data URL, we are allowed to set the mimetype which indicates the type of data to download. Documentation:

Data URLs are composed of four parts: a prefix (data:), a MIME type indicating the type of data, an optional base64 token if non-textual, and the data itself. (Source: MDN Web Docs: Data URLs.)

Components:

• <a ...> : The link tag.
• href="data:video/mp4,http://www.example.com/video.mp4" : Here we are setting the link to the a data: with a header preconfigured to video/mp4. This is followed by the header mimetype. I.E., for a .txt file, it would would be text/plain. And then a comma separates it from the link we want to download.
• target="_blank" : This indicates a new tab should be opened, it's not essential, but it helps guide the browser to the desired behavior.
• download: This is the name of the file you're downloading.

Your problem is with casting the float to an int, losing precision. You should also multiply with the factor and not divide.

Do this:

int dp = (int)(pixel*getResources().getDisplayMetrics().density);

If your implementation provides a 64-bit integer type, you may get a different (incorrect) answer by using fmin or fmax. Your 64-bit integers will be converted to doubles, which will (at least usually) have a significand that's smaller than 64-bits. When you convert such a number to a double, some of the least significant bits can/will be lost completely.

This means that two numbers that were really different could end up equal when converted to double -- and the result will be that incorrect number, that's not necessarily equal to either of the original inputs.

The limitation relates to the simplified CommonJS syntax vs. the normal callback syntax:

• http://requirejs.org/docs/whyamd.html#commonjscompat
• https://github.com/jrburke/requirejs/wiki/Differences-between-the-simplified-CommonJS-wrapper-and-standard-AMD-define

Loading a module is inherently an asynchronous process due to the unknown timing of downloading it. However, RequireJS in emulation of the server-side CommonJS spec tries to give you a simplified syntax. When you do something like this:

var foomodule = require('foo');
// do something with fooModule

What's happening behind the scenes is that RequireJS is looking at the body of your function code and parsing out that you need 'foo' and loading it prior to your function execution. However, when a variable or anything other than a simple string, such as your example...

var module = require(path); // Call RequireJS require

...then Require is unable to parse this out and automatically convert it. The solution is to convert to the callback syntax;

var moduleName = 'foo';
require([moduleName], function(fooModule){
    // do something with fooModule
})

Given the above, here is one possible rewrite of your 2nd example to use the standard syntax:

define(['dyn_modules'], function (dynModules) {
    require(dynModules, function(){
        // use arguments since you don't know how many modules you're getting in the callback
        for (var i = 0; i < arguments.length; i++){
            var mymodule = arguments[i];
            // do something with mymodule...
        }
    });

});

EDIT: From your own answer, I see you're using underscore/lodash, so using _.values and _.object can simplify the looping through arguments array as above.

Simply use a class literal, i.e. NameOfClass.class

body{
  margin:0;
  padding:0 0 0 0;
}
div#header{
  position:absolute;
  top:0;
  left:0;
  width:100%;
  height:25;
}
@media screen{
 body>div#header{
   position: fixed;
 }
}
* html body{
  overflow:hidden;
} 
* html div#content{
  height:100%;
  overflow:auto;
}

bash:

LD_LIBRARY_PATH=my_path
sqsub -np $1 /path/to/executable

Similar, in Python:

import os
import subprocess
import sys

os.environ['LD_LIBRARY_PATH'] = "my_path" # visible in this process + all children
subprocess.check_call(['sqsub', '-np', sys.argv[1], '/path/to/executable'],
                      env=dict(os.environ, SQSUB_VAR="visible in this subprocess"))

When serialising an XML document to a .NET string, the encoding must be set to UTF-16. Strings are stored as UTF-16 internally, so this is the only encoding that makes sense. If you want to store data in a different encoding, you use a byte array instead.

SQL Server works on a similar principle; any string passed into an xml column must be encoded as UTF-16. SQL Server will reject any string where the XML declaration does not specify UTF-16. If the XML declaration is not present, then the XML standard requires that it default to UTF-8, so SQL Server will reject that as well.

Bearing this in mind, here are some utility methods for doing the conversion.

public static string Serialize<T>(T value) {

    if(value == null) {
        return null;
    }

    XmlSerializer serializer = new XmlSerializer(typeof(T));

    XmlWriterSettings settings = new XmlWriterSettings()
    {
        Encoding = new UnicodeEncoding(false, false), // no BOM in a .NET string
        Indent = false,
        OmitXmlDeclaration = false
    };

    using(StringWriter textWriter = new StringWriter()) {
        using(XmlWriter xmlWriter = XmlWriter.Create(textWriter, settings)) {
            serializer.Serialize(xmlWriter, value);
        }
        return textWriter.ToString();
    }
}

public static T Deserialize<T>(string xml) {

    if(string.IsNullOrEmpty(xml)) {
        return default(T);
    }

    XmlSerializer serializer = new XmlSerializer(typeof(T));

    XmlReaderSettings settings = new XmlReaderSettings();
    // No settings need modifying here

    using(StringReader textReader = new StringReader(xml)) {
        using(XmlReader xmlReader = XmlReader.Create(textReader, settings)) {
            return (T) serializer.Deserialize(xmlReader);
        }
    }
}

Pure Virtual Functions are mostly used to define:

a) abstract classes

These are base classes where you have to derive from them and then implement the pure virtual functions.

b) interfaces

These are 'empty' classes where all functions are pure virtual and hence you have to derive and then implement all of the functions.

Pure virtual functions are actually functions which have no implementation in base class and have to be implemented in derived class.

You should have a look at moment which is a python port of the excellent js lib momentjs.

One advantage of it is the support of ISO 8601 strings formats, as well as a generic "% format" :

import moment
time_string='2012-10-09T19:00:55Z'

m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday

Result:

2012-10-09 19:10

You have to use a Class instance because of the generic type erasure during compilation.

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
    try {
        return clazz.cast(o);
    } catch(ClassCastException e) {
        return null;
    }
}

The declaration of that method is:

public T cast(Object o)

This can also be used for array types. It would look like this:

final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);

Note that when someObject is passed to convertToInstanceOfObject it has the compile time type Object.

You can get it with .outerHeight().

Sometimes, it will return 0. For the best results, you can call it in your div's ready event.

To be safe, you should not set the height of the div to x. You can keep its height auto to get content populated properly with the correct height.

$('#x').ready( function(){
// alerts the height in pixels
alert($('#x').outerHeight());
})

You can find a detailed post here.

found a solution but not sure the performance if the map has large size, useful for normal case.

   /**
     * sort HashMap<String, CustomData> by value
     * CustomData needs to provide compareTo() for comparing CustomData
     * @param map
     */

    public void sortHashMapByValue(final HashMap<String, CustomData> map) {
        ArrayList<String> keys = new ArrayList<String>();
        keys.addAll(map.keySet());
        Collections.sort(keys, new Comparator<String>() {
            @Override
            public int compare(String lhs, String rhs) {
                CustomData val1 = map.get(lhs);
                CustomData val2 = map.get(rhs);
                if (val1 == null) {
                    return (val2 != null) ? 1 : 0;
                } else if (val1 != null) && (val2 != null)) {
                    return = val1.compareTo(val2);
                }
                else {
                    return 0;
                }
            }
        });

        for (String key : keys) {
            CustomData c = map.get(key);
            if (c != null) {
                Log.e("key:"+key+", CustomData:"+c.toString());
            } 
        }
    }

In order to avoid duplicate code, I recommend you to define the color once, for both states:

a, a:visited{
     color: /* some color */;
}

This, indeeed, will mantain your <a> color (whatever this color is) even when the link has been visited.

Notice that, if the color of the element inside of the <a> is being inherited (e.g. the color is set in the body), you could do the following trick:

a, a:visited {
    color: inherit;
}

Using file extension and getimagesize function to detect if uploaded file has right format is just the entry level check and it can simply bypass by uploading a file with true extension and some byte of an image header but wrong content.

for being secure and safe you may make thumbnail/resize (even with original image sizes) the uploaded picture and save this version instead the uploaded one. Also its possible to get uploaded file content and search it for special character like <?php to find the file is image or not.

Remove below code

s.send("Hello server!")

because your sending s.send("Hello server!") to server, so your output file is somewhat more in size.

I know I'm late but I hope this is useful. Logic is for taking one line at a time if the user wants to enter many lines

int main() 
{ 
int t;                    // no of lines user wants to enter
cin>>t;
string str;
cin.ignore();            // for clearing newline in cin
while(t--)
{
    getline(cin,str);    // accepting one line, getline is teminated when newline is found 
    cout<<str<<endl; 
}
return 0; 
}

You can try creating a css for your font with font-face (like explained here)

Step #1

Create a css file with font face and place it somewhere, like in assets/fonts

customfont.css

@font-face {
    font-family: YourFontFamily;
    src: url("/assets/font/yourFont.otf") format("truetype");
}

Step #2

Add the css to your .angular-cli.json in the styles config

"styles":[
 //...your other styles
 "assets/fonts/customFonts.css"
 ]

Do not forget to restart ng serve after doing this

Step #3

Use the font in your code

component.css

span {font-family: YourFontFamily; }

This seems like a very simple solution:

import numpy as np
def shuffle_in_unison(a,b):

    assert len(a)==len(b)
    c = np.arange(len(a))
    np.random.shuffle(c)

    return a[c],b[c]

a =  np.asarray([[1, 1], [2, 2], [3, 3]])
b =  np.asarray([11, 22, 33])

shuffle_in_unison(a,b)
Out[94]: 
(array([[3, 3],
        [2, 2],
        [1, 1]]),
 array([33, 22, 11]))

I have replaced FlatList with SectionList and it is updates properly on state change.

<SectionList
  keyExtractor={(item) => item.entry.entryId} 
  sections={section}
  renderItem={this.renderEntries.bind(this)}
  renderSectionHeader={() => null}
/>

The only thing need to keep in mind is that section have diff structure:

const section = [{
  id: 0,
  data: this.state.data,
}]

In my case, I was doing: curl <blabla> | jq | grep <blibli>

With jq . it worked: curl <blabla> | jq . | grep <blibli>

A little jQuery fix:

$(function(){
    var chbxs = $(':checkbox[required]');
    var namedChbxs = {};
    chbxs.each(function(){
        var name = $(this).attr('name');
        namedChbxs[name] = (namedChbxs[name] || $()).add(this);
    });
    chbxs.change(function(){
        var name = $(this).attr('name');
        var cbx = namedChbxs[name];
        if(cbx.filter(':checked').length>0){
            cbx.removeAttr('required');
        }else{
            cbx.attr('required','required');
        }
    });
});

You can try creating DBMS_XMLPARSER.parser object from the CLOB XML and get a DBMS_XMLDOM.DOMDocument object from it. Then use DBMS_XMLDOM package methods to get the value of any node.

   xml_            CLOB := 'X';
   p               DBMS_XMLPARSER.parser;
   doc_            DBMS_XMLDOM.DOMDocument;

      -- Convert the CLOB into a XML-document
      P := DBMS_XMLPARSER.newparser();
      -- Parse the clob and get the XML-document
      DBMS_XMLPARSER.parseclob(p, xml_);
      doc_ := DBMS_XMLPARSER.getDocument(p);

Then use the below methods to extract node value

DBMS_XMLDOM.getElementsByTagName(doc_, 'NodeName'); DBMS_XMLDOM.GetNodeValue(node_obj_);

Refer more about DBMS_XMLDOM methods here.

In Postgres, you can make almost any single value query return a value or null by wrapping it:

SELECT (SELECT <query>) AS value

and hence avoid complexity in the caller.

You can use git for exactly this purpose. Basically, you create a git repository in folder A (the repo is in A/.git), then copy A/.git to B/.git, then change to B folder and compare simply by running git diff. And the --exclude functionality can be achieved with .gitignore.

So, sticking to your example (but using bash shell on Linux):

# Create a Git repo in current_vss
pushd current_vss
printf ".svn\n*.vspscc\n*.scc" >> .gitignore
git init && git add . && git commit -m 'initial'
popd

# Copy the repo to current_svn and compare
cp -r current_vss/.git* current_svn/
pushd current_svn
git diff

Personally I would suggest this is an error as opposed to a setting that needs adjusting. In my code it was because I had a class that had the same name as a library within one of my controllers and it seemed to trip it up.

Output errors and see where this is being triggered.

I ran into this same issue and none of what I was seeing here was working. If you are listing your Component in the app-routing.module issue you may have run into the same problem I was having.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';
import { NavbarComponent } from './navbar/navbar.component';
import { TopbarComponent } from './topbar/topbar.component';
import { FooterbarComponent } from './footerbar/footerbar.component';
import { MRDBGlobalConstants } from './shared/mrdb.global.constants';
import {AppRoutingModule} from './app.routing';
import {HomeModule} from './Home/home.module';
// import HomeComponent here

@NgModule({
  declarations: [
    AppComponent,
    FooterbarComponent,
    TopbarComponent,
    NavbarComponent,
    // add HomeComponent here
  ],
  imports: [
    BrowserModule,
    HttpModule,
    AppRoutingModule,
    HomeModule  // remove this

  ],
  providers: [MRDBGlobalConstants],
  bootstrap: [AppComponent]
})
export class AppModule { }

home/index.ts

export * from './';

app-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './components';

const routes: Routes = [
    { path: 'app/home', component: HomeComponent },
    { path: '', redirectTo: 'app/home', pathMatch: 'full' },
    { path: '**', redirectTo: 'app/home' }
];

@NgModule({
    imports: [RouterModule.forRoot(routes)],
    exports: [RouterModule]
})
export class AppRoutingModule { }

home/home.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
// import { HomeComponent } from './home.component'; This would cause app to break
import { HomeComponent } from './';
@NgModule({
  imports: [
    CommonModule
  ],
  exports: [HomeComponent],
  declarations: [HomeComponent]
})
export class HomeModule { }

I won't claim to understand exactly why this is the case, but when using indexing to export components (and I would assume the same for services, etc.), when referencing the same component in separate modules you need to import them from the same file, in this case the index, in order to avoid this issue.

If you have even the relative pathname (in this case it appears to be ./) you can open files relative to your script file(s). I use Perl, but the same general solution can apply: I split the directory into an array of folders, then pop off the last element (the script), then push (or for you, append) on whatever I want, and then join them together again, and BAM! I have a working pathname that points to exactly where I expect it to point, relative or absolute.

Of course, there are better solutions, as posted. I just kind of like mine.

Here is a recursive way on how to do it using ternary operators both for the recursion and decision whether you came across a min number or not.

const findMin = (arr, min, i) => arr.length === i ? min :
  findMin(arr, min = arr[i] < min ? arr[i] : min, ++i)

Code snippet:

const findMin = (arr, min, i) => arr.length === i ? min :_x000D_
  findMin(arr, min = arr[i] < min ? arr[i] : min, ++i)_x000D_
  _x000D_
const arr = [5, 34, 2, 1, 6, 7, 9, 3];_x000D_
const min = findMin(arr, arr[0], 0)_x000D_
console.log(min);

This probably works for a lot of things but it's not enough for Maven and certainly not for the maven compiler plugin.

Check Mike's answer to his own question here: stackoverflow question 24705877

This solved the issue for me both command line AND within eclipse.

Also, @LinGao answer to stackoverflow question 2503658 and the use of the $JAVACMD variable might help but I haven't tested it myself.

What type of granularity are you looking for? You can typically get by with:

$http.get(url).then(
  //success function
  function(results) {
    //do something w/results.data
  },
  //error function
  function(err) {
    //handle error
  }
);

I've found that "finally" and "catch" are better off when chaining multiple promises.

The below command can set the icon on an executable file.

Remember the ".ico" file should present in the place of the path given in "Path_of_.ico_file".

pyinstaller.exe --onefile --windowed --icon="Path_of_.ico_file" app.py

For example:

If the app.py file is present in the current directory and app.ico is present inside the Images folder within the current directory.

Then the command should be as below. The final executable file will be generated inside the dist folder

pyinstaller.exe --onefile --windowed --icon=Images\app.ico app.py

    <html>
<script type="text/javascript">
var myJSONObject = {"bindings": 11};
alert(myJSONObject);

var stringJson =JSON.stringify(myJSONObject);
alert(stringJson);
</script>
</html>

I would like to add that in case in you create local variables within the loop, they need to be expanded using the bang(!) notation as well. Extending the example at https://stackoverflow.com/a/2919699 above, if we want to create counter-based output filenames

set TEXT_T="myfile.txt"

set /a c=1

setlocal ENABLEDELAYEDEXPANSION

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
    set /a c=c+1
    set OUTPUT_FILE_NAME=output_!c!.txt
    echo Output file is !OUTPUT_FILE_NAME!
    echo %%i, !c!
)

endlocal

I had this problem with last version of numpy 1.16.x

Problem resolved with

python3 -m pip uninstall numpy

python3 -m pip install numpy==1.14.0

I have a naive solution but useful. Here is the code:

<Grid Name="TVGrid" Background="#7F000000">  <ScrollBar Background="Black" Orientation="Vertical" Height="35" HorizontalAlignment="Left" Margin="215,254,0,0" Minimum="0" Maximum="10" LargeChange="10" Value="{Binding ElementName=channeltext2, Path=Text}" x:Name="scroll" VerticalAlignment="Top" Width="12" RenderTransformOrigin="0.5,0.5" ValueChanged="scroll_ValueChanged" >  
        <ScrollBar.RenderTransform>  
            <TransformGroup>  
                <ScaleTransform/>  
                <SkewTransform/>  
                <RotateTransform Angle="-180"/>  
                <TranslateTransform/>  
            </TransformGroup>  
        </ScrollBar.RenderTransform>  
    </ScrollBar>  
    <TextBox Name="channeltext" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  
    <TextBox Name="channeltext2" Visibility="Hidden" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  </Grid>  

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

I think Apple are covering their backs a little here for a potentially kludgy piece of API.

  [self dismissViewControllerAnimated:NO completion:nil]

Is actually a bit of a fiddle. Although you can - legitimately - call this on the presented view controller, all it does is forward the message on to the presenting view controller. If you want to do anything over and above just dismissing the VC, you will need to know this, and you need to treat it much the same way as a delegate method - as that's pretty much what it is, a baked-in somewhat inflexible delegate method.

Perhaps they've come across loads of bad code by people not really understanding how this is put together, hence their caution.

But of course, if all you need to do is dismiss the thing, go ahead.

My own approach is a compromise, at least it reminds me what is going on:

  [[self presentingViewController] dismissViewControllerAnimated:NO completion:nil]

[Swift]

  self.presentingViewController?.dismiss(animated: false, completion:nil)

An addition to previous answers, to use Request.Params["__EVENTTARGET"] you have to set the option:

buttonName.UseSubmitBehavior = false;

When programmatically creating server, you can add message body writers for json/xml by setting Providers.

JAXRSServerFactoryBean bean = new JAXRSServerFactoryBean();
bean.setAddress("http://localhost:9000/");

List<Object> providers = new ArrayList<Object>();
providers.add(new JacksonJaxbJsonProvider());
providers.add(new JacksonJaxbXMLProvider());
bean.setProviders(providers);

List<Class< ? >> resourceClasses = new ArrayList<Class< ? >>();
resourceClasses.add(YourRestServiceImpl.class);
bean.setResourceClasses(resourceClasses);

bean.setResourceProvider(YourRestServiceImpl.class, new SingletonResourceProvider(new YourRestServiceImpl()));

BindingFactoryManager manager = bean.getBus().getExtension(BindingFactoryManager.class);
JAXRSBindingFactory restFactory = new JAXRSBindingFactory();
restFactory.setBus(bean.getBus());
manager.registerBindingFactory(JAXRSBindingFactory.JAXRS_BINDING_ID, restFactory);

bean.create();

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

wmode=opaque or transparent at the beginning of my query string didnt solve anything. This issue for me only occurs on Chrome, and not across even all computers. Just one cpu. It occurs in vimeo embeds as well, and possibly others.

My solution to to attach to the 'shown' and 'hidden' event of the bootstrap modals I am using, add a class which sets the iframe to 1x1 pixels, and remove the class when the modal closes. Seems like it works and is simple to implement.

SETUSER could work, having a user, even an orphaned user in the DB with the default schema needed. But SETUSER is on the legacy not supported for ever list. So a similar alternative would be to setup an application role with the needed default schema, as long as no cross DB access is needed, this should work like a treat.

You could use ng-init in an outer div:

<div ng-init="param='value';">
    <div ng-controller="BasketController" >
        <label>param: {{value}}</label>
    </div>
</div>  

The parameter will then be available in your controller's scope:

function BasketController($scope) {
        console.log($scope.param);
}

$(document).ready(function() {
    $('#abc_frame').attr('src',url);
})

I like to use the recursive pattern for this scenario. For example, something like this:

// If config is an array of queries
var config = JSON.parse(queries.querrryArray);   

// Array of results
var results;

processQueries(config);

function processQueries(queries) {
    var searchQuery;

    if (queries.length == 0) {
        // All queries complete
        res.writeHead(200, {'content-type': 'application/json'});
        res.end(JSON.stringify({results: results}));
        return;
    }

    searchQuery = queries.pop();

    search(searchQuery, function(result) {
        results.push(JSON.stringify({result: result}); 
        processQueries();            
    });

}

processQueries is a recursive function that will pull a query element out of an array of queries to process. Then the callback function calls processQueries again when the query is complete. The processQueries knows to end when there are no queries left.

It is easiest to do this using arrays, but it could be modified to work with object key/values I imagine.

I encounted this error and found that it was because the "strict" parameter was set to true in the tsconfig.json file. Just set it "false" (obviously). In my case I had generated the tsconfig file from the cmd prompt and simply missed the "strict" parameter, which was located further down in the file.

BeautifulSoup(text, features="html.parser").text 

For the people who were seeking deep info in my answer, sorry.

I'll explain it.

Beautifulsoup is a widely use python package that helps the user (developer) to interact with HTML within python.

The above like just take all the HTML text (text) and cast it to Beautifulsoup object - that means behind the sense its parses everything up (Every HTML tag within the given text)

Once done so, we just request all the text from within the HTML object.

Try with this HTML5 tips

  WebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);

Add an extra apostrophe ' to the MessageFormat pattern String to ensure the ' character is displayed

String text = 
     java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
                                         ^

An apostrophe (aka single quote) in a MessageFormat pattern starts a quoted string and is not interpreted on its own. From the javadoc

A single quote itself must be represented by doubled single quotes '' throughout a String.

The String You\\'re is equivalent to adding a backslash character to the String so the only difference will be that You\re will be produced rather than Youre. (before double quote solution '' applied)

$BASH_SOURCE gives the correct answer when sourcing the script.

This however includes the path so to get the scripts filename only, use:

$(basename $BASH_SOURCE) 

I would answer this with multiple options actually, the some of which actually render in the body.

• Place library script such as the jQuery library in the head section.
• Place normal script in the head unless it becomes a performance/page load issue.
• Place script associated with includes, within and at the end of that include. One example of this is .ascx user controls in asp.net pages - place the script at the end of that markup.
• Place script that impacts the render of the page at the end of the body (before the body closure).
• do NOT place script in the markup such as <input onclick="myfunction()"/> - better to put it in event handlers in your script body instead.
• If you cannot decide, put it in the head until you have a reason not to such as page blocking issues.

Footnote: "When you need it and not prior" applies to the last item when page blocking (perceptual loading speed). The user's perception is their reality—if it is perceived to load faster, it does load faster (even though stuff might still be occurring in code).

Side note: IF you place script blocks within markup, it may effect layout in certain browsers by taking up space (ie7 and opera 9.2 are known to have this issue) so place them in a hidden div (use a css class like: .hide { display: none; visibility: hidden; } on the div)

Standards: Note that the standards allow placement of the script blocks virtually anywhere if that is in question: http://www.w3.org/TR/1999/REC-html401-19991224/sgml/dtd.html and http://www.w3.org/TR/xhtml11/xhtml11_dtd.html

EDIT2: Note that whenever possible (always?) you should put the actual Javascript in external files and reference those - this does not change the pertinent sequence validity.

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

@aymeric answer wont print the numbers in their natural order, but this code will. Explanation at the end.

public class Driver {

                            e.printStackTrace();
                        }
                    }
                }
            }
        });
        Thread t2 = new Thread(new Runnable() {
            public void run() {

                for (int itr = 2; itr < 51; itr = itr + 2) {

In order to achieve so, the run methods of the two threads above have to be called one after the other, i.e. they need to be synchronized and I am achieving that using locks.

The code works like this: t1.run prints the odd number and notifies any waiting thread that it is going to release the lock, then goes into a wait state.

At this point t2.run is invoked, it prints the next even number, notifies other threads that it is about to release the lock it holds and then goes into wait state.

This continues till the itr in t2.run() reaches 50, at this point our goal has been achieved and we need to kill these two threads.

By breaking, I avoid calling lock.wait() in t2.run and t2 thread is thus shutdown, the control will now go to t1.run since it was waiting to acquire the lock; but here itr value will be > 51 and we will come out of its run(), thus shutting down the thread.

If break is not used in t2.run(), though we will see numbers 1 to 50 on the screen but the two threads will get into a deadlock situation and continue to be in wait state.

A small update for the new Skype options window. Please follow this:

Go to Tools ? Options ? Advanced ? Connection and uncheck the box use port 80 and 443 as alternatives for incoming connections.

It worked for me:

File file = new File(getApplicationContext().getFilesDir(),"whatever.txt");
    if(file.exists()){
       //Do something
    }
    else{
       //Nothing
     }

As per my knowledge Inline sytle comes first so css class should not work.

Use Jquery as

$(document).ready(function(){

   $("#demoFour li").css("display","inline");
  });

You can also try 

#demoFour li { display:inline !important;}

Try to get your archive using wget, I had the same issue when I was downloading archive through browser. Than I just copy archive link and in terminal use the command:

wget http://PATH_TO_ARCHIVE

I currently am working on a codebase where two of the people working on it blindly subscribe to the "single point of exit" theory and I can tell you that from experience, it's a horrible horrible practice. It makes code extremely difficult to maintain and I'll show you why.

With the "single point of exit" theory, you inevitably wind up with code that looks like this:

function()
{
    HRESULT error = S_OK;

    if(SUCCEEDED(Operation1()))
    {
        if(SUCCEEDED(Operation2()))
        {
            if(SUCCEEDED(Operation3()))
            {
                if(SUCCEEDED(Operation4()))
                {
                }
                else
                {
                    error = OPERATION4FAILED;
                }
            }
            else
            {
                error = OPERATION3FAILED;
            }
        }
        else
        {
            error = OPERATION2FAILED;
        }
    }
    else
    {
        error = OPERATION1FAILED;
    }

    return error;
}

Not only does this make the code very hard to follow, but now say later on you need to go back and add an operation in between 1 and 2. You have to indent just about the entire freaking function, and good luck making sure all of your if/else conditions and braces are matched up properly.

This method makes code maintenance extremely difficult and error prone.

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

This is probably the most elegant way to do it.
Right in the PDO constructor call, but avoiding the buggy charset option (as mentioned above):

$connect = new PDO(
  "mysql:host=$host;dbname=$db", 
  $user, 
  $pass, 
  array(
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
    PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
  )
);

Works great for me.

I'll give my input because it helps me understand what im doing.

To make an auto scrolling slide show that has a 3 second wait I did the following:

var isPlaying = true;

function autoPlay(playing){
   var delayTime = 3000;
   var timeIncrement = 3000;

   if(playing){
        for(var i=0; i<6; i++){//I have 6 images
            setTimeout(nextImage, delayTime);
            delayTime += timeIncrement;
        }
        isPlaying = false;

   }else{
       alert("auto play off");
   }
}

autoPlay(isPlaying);

Remember that when executing setTimeout() like this; it will execute all time out functions as if they where executed at the same time assuming that in setTimeout(nextImage, delayTime);delay time is a static 3000 milliseconds.

What I did to account for this was add an extra 3000 milli/s after each for loop incrementation via delayTime += timeIncrement;.

For those who care here is what my nextImage() looks like:

function nextImage(){
    if(currentImg === 1){//change to img 2
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[1].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[1];
        imgDescription.innerHTML = imgDescText[1];

        currentImg = 2;
    }
    else if(currentImg === 2){//change to img 3
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[2].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[2];
        imgDescription.innerHTML = imgDescText[2];

        currentImg = 3;
    }
    else if(currentImg === 3){//change to img 4
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[3].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[3];
        imgDescription.innerHTML = imgDescText[3];

        currentImg = 4;
    }
    else if(currentImg === 4){//change to img 5
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[4].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[4];
        imgDescription.innerHTML = imgDescText[4];

        currentImg = 5;
    }
    else if(currentImg === 5){//change to img 6
    for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[5].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[5];
        imgDescription.innerHTML = imgDescText[5];

        currentImg = 6;
    }
    else if(currentImg === 6){//change to img 1
        for(var i=0; i<6; i++){
            images[i].style.zIndex = "0";
        }
        images[0].style.zIndex = "1";
        imgNumber.innerHTML = imageNumber_Text[0];
        imgDescription.innerHTML = imgDescText[0];

        currentImg = 1;
    }
}

You can use the readline module to read from stdin line by line:

var readline = require('readline');
var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  terminal: false
});

rl.on('line', function(line){
    console.log(line);
})

This is something I use:

$cryptoStrong = true; // can be false
$length = 16; // Any length you want
$bytes = openssl_random_pseudo_bytes($length, $cryptoStrong);
$randomString = bin2hex($bytes);

You can see the Docs for openssl_random_pseudo_bytes here, and the Docs for bin2hex here

use os.path.isdir(path)

General rule is the following:

• If select contains single expression and it's an entity, then result is that entity
• If select contains single expression and it's a primitive, then result is that primitive
• If select contains multiple expressions, then result is Object[] containing the corresponding primitives/entities

So, in your case list is a List<Object[]>.

With slight modification, the answer above works with arrays of arbitrary dimension (1d, 2d, 3d, ...):

def find_nearest(a, a0):
    "Element in nd array `a` closest to the scalar value `a0`"
    idx = np.abs(a - a0).argmin()
    return a.flat[idx]

Or, written as a single line:

a.flat[np.abs(a - a0).argmin()]

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

You need to install Microsoft Visual C++ 14.0 to install pycrypto:

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

In the comments you ask which link to use. Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.

In the comments you ask about methods of installing pycrypto that do not require installing a compiler. The binaries in the links appear to be for earlier versions of Python than you are using. One link is to a binary in a DropBox account.

I do not recommend downloading binary versions of cryptography libraries provided by third parties. The only way to guarantee that you are getting a version of pycrypto that is compatible with your version of Python and has not been built with any backdoors is to build it from the source.

After you have installed Visual C++, just re-run the original command:

pip install -U steem

To find out what the various install options mean, run this command:

pip help install

The help for the -U option says

-U, --upgrade        Upgrade all specified packages to the newest available
                     version. The handling of dependencies depends on the
                     upgrade-strategy used.

If you do not already have the steem library installed, you can run the command without the -U option.

It gets a little bit more complicated if you want to add the background to a specific modal. One way of solving that is to add and call something like this function instead of showing the modal directly:

function showModal(selector) {
    $(selector).modal('show');
    $('.modal-backdrop').addClass('background-backdrop');
}

Any css can then be applied to the background-backdrop class.

GoDaddy is currently (Feb '13) supporting modification of FastCGI for some accounts using PHP 5.2.x or earlier. See GoDaddy article "Disabling FastCGI in Your Hosting Account".
(In my case, this is apparently necessary to help get the current version of LimeSurvey (2.0) towards a running state.)

 textBoxX1.Focus();
 this.ActiveControl = textBoxX1;
 textBoxX1.SelectAll();

In my first answer the logic is shown for those who want to go with the logic only.

I think I was not able to make clear to @chalukya3545, that's why I am adding the whole code to let him know the exact flow of the code.

Add this permissions to your AndroidManifest.xml file:

 <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
 <uses-permission android:name="android.permission.BLUETOOTH" />  
 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

The output for this code will look like this.

If you use it extensively (a lot of written lines), you can subclass 'file':

class cfile(file):
    #subclass file to have a more convienient use of writeline
    def __init__(self, name, mode = 'r'):
        self = file.__init__(self, name, mode)

    def wl(self, string):
        self.writelines(string + '\n')

Now it offers an additional function wl that does what you want:

fid = cfile('filename.txt', 'w')
fid.wl('appends newline charachter')
fid.wl('is written on a new line')
fid.close()

Maybe I am missing something like different newline characters (\n, \r, ...) or that the last line is also terminated with a newline, but it works for me.

UDP does have less overhead and is good for doing things like streaming real time data like audio or video, or in any case where it is ok if data is lost.

What do you think about this approach?

with open(filename) as data:
    datalines = (line.rstrip('\r\n') for line in data)
    for line in datalines:
        ...do something awesome...

Generator expression avoids loading whole file into memory and with ensures closing the file

The accepted answer previously contained new Buffer(), which is considered a security issue in node versions greater than 6 (although it seems likely for this usecase that the input can always be coerced to a string).

The Buffer constructor is deprecated according to the documentation.

Here is an example of a vulnerability that can result from using it in the ws library.

The code snippets should read:

console.log(Buffer.from("Hello World").toString('base64'));
console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'));

The answer by Jared Forsyth is horribly wrong and outdated. It follows a whole set of antipatterns such as usage of stopPropagation, initializing state from props, usage of jQuery, nested objects in state and has some odd dragging state field. If being rewritten, the solution will be the following, but it still forces virtual DOM reconciliation on every mouse move tick and is not very performant.

UPD. My answer was horribly wrong and outdated. Now the code alleviates issues of slow React component lifecycle by using native event handlers and style updates, uses transform as it doesn't lead to reflows, and throttles DOM changes through requestAnimationFrame. Now it's consistently 60 FPS for me in every browser I tried.

const throttle = (f) => {
    let token = null, lastArgs = null;
    const invoke = () => {
        f(...lastArgs);
        token = null;
    };
    const result = (...args) => {
        lastArgs = args;
        if (!token) {
            token = requestAnimationFrame(invoke);
        }
    };
    result.cancel = () => token && cancelAnimationFrame(token);
    return result;
};

Here are the difference between POST, PUT and PATCH methods of a HTTP protocol.

POST

A HTTP.POST method always creates a new resource on the server. Its a non-idempotent request i.e. if user hits same requests 2 times it would create another new resource if there is no constraint.

http post method is like a INSERT query in SQL which always creates a new record in database.

Example: Use POST method to save new user, order etc where backend server decides the resource id for new resource.

PUT

In HTTP.PUT method the resource is first identified from the URL and if it exists then it is updated otherwise a new resource is created. When the target resource exists it overwrites that resource with a complete new body. That is HTTP.PUT method is used to CREATE or UPDATE a resource.

http put method is like a MERGE query in SQL which inserts or updates a record depending upon whether the given record exists.

PUT request is idempotent i.e. hitting the same requests twice would update the existing recording (No new record created). In PUT method the resource id is decided by the client and provided in the request url.

Example: Use PUT method to update existing user or order.

PATCH

A HTTP.PATCH method is used for partial modifications to a resource i.e. delta updates.

http patch method is like a UPDATE query in SQL which sets or updates selected columns only and not the whole row.

Example: You could use PATCH method to update order status.

PATCH /api/users/40450236/order/10234557

Request Body: {status: 'Delivered'}

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

The call to InitializeComponent() (which is usually called in the default constructor of at least Window and UserControl) is actually a method call to the partial class of the control (rather than a call up the object hierarchy as I first expected).

This method locates a URI to the XAML for the Window/UserControl that is loading, and passes it to the System.Windows.Application.LoadComponent() static method. LoadComponent() loads the XAML file that is located at the passed in URI, and converts it to an instance of the object that is specified by the root element of the XAML file.

In more detail, LoadComponent creates an instance of the XamlParser, and builds a tree of the XAML. Each node is parsed by the XamlParser.ProcessXamlNode(). This gets passed to the BamlRecordWriter class. Some time after this I get a bit lost in how the BAML is converted to objects, but this may be enough to help you on the path to enlightenment.

Note: Interestingly, the InitializeComponent is a method on the System.Windows.Markup.IComponentConnector interface, of which Window/UserControl implement in the partial generated class.

Hope this helps!

This works for me:

for each series, use a random rgb colour generator

c = color[np.random.random_sample(), np.random.random_sample(), np.random.random_sample()]

with jQuery :

$("#foo").find("*").remove();

By default, Homebrew installs packages to your /usr/local. Macport commands require sudo to install and upgrade (similar to apt-get in Ubuntu).

For more detail:

This site suggests using Hombrew: http://deephill.com/macports-vs-homebrew/

whereas this site lists the advantages of using Macports: http://arstechnica.com/civis/viewtopic.php?f=19&t=1207907

I also switched from Ubuntu recently, and I enjoy using homebrew (it's simple and easy to use!), but if you feel attached to using sudo, Macports might be the better way to go!

*Make sure you update your linux box first

yum update

In case someone still has this problem, this is a valid solution:

centos-release : rpm -q centos-release

Centos 6.*

wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm

Centos 5.*

wget http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
rpm -Uvh remi-release-5*.rpm

Then just do this to update:

yum --enablerepo=remi upgrade php-mbstring

Or this to install:

yum --enablerepo=remi install php-mbstring

here is simple solution i hope it will help you. here's a simple example to improve answer.

$('[type="radio"]').click(function () {

            if ($(this).attr('checked')) {

                $(this).removeAttr('checked');
                $(this).prop('checked',false);

            } else {

                $(this).attr('checked', 'checked');

            }
        });

t.start();
//
//
t.start();

output:

Runtime Excpetion: IllegalThreadStateException

We cant start the Thread again, it will throw IllegalStateException.

TL;DR

The difference between the commands is that one provides you with a tag message while the other doesn't. An annotated tag has a message that can be displayed with git-show(1), while a tag without annotations is just a named pointer to a commit.

More About Lightweight Tags

According to the documentation: "To create a lightweight tag, don’t supply any of the -a, -s, or -m options, just provide a tag name". There are also some different options to write a message on annotated tags:

• When you use git tag <tagname>, Git will create a tag at the current revision but will not prompt you for an annotation. It will be tagged without a message (this is a lightweight tag).
• When you use git tag -a <tagname>, Git will prompt you for an annotation unless you have also used the -m flag to provide a message.
• When you use git tag -a -m <msg> <tagname>, Git will tag the commit and annotate it with the provided message.
• When you use git tag -m <msg> <tagname>, Git will behave as if you passed the -a flag for annotation and use the provided message.

Basically, it just amounts to whether you want the tag to have an annotation and some other information associated with it or not.

Pardon my ignorance, but why are you using $('.salesperson') instead of $('#salesperson') when dealing with an ID?

I realise that this is a rather old post and you have probably moved on.

But I had the same problem as you so I decided to write my own program.

The problem with the "xml -> xsd -> classes" route for me was that it just generated a lump of code that was completely unmaintainable and I ended up turfing it.

It is in no way elegant but it did the job for me.

I actually tried to implement connection pooling on the django end using:

https://github.com/gmcguire/django-db-pool

but I still received this error, despite lowering the number of connections available to below the standard development DB quota of 20 open connections.

There is an article here about how to move your postgresql database to the free/cheap tier of Amazon RDS. This would allow you to set max_connections higher. This will also allow you to pool connections at the database level using PGBouncer.

https://www.lewagon.com/blog/how-to-migrate-heroku-postgres-database-to-amazon-rds

UPDATE:

Heroku responded to my open ticket and stated that my database was improperly load balanced in their network. They said that improvements to their system should prevent similar problems in the future. Nonetheless, support manually relocated my database and performance is noticeably improved.

You can map the list of stations to ReactElements.

With React >= 16, it is possible to return multiple elements from the same component without needing an extra html element wrapper. Since 16.2, there is a new syntax <> to create fragments. If this does not work or is not supported by your IDE, you can use <React.Fragment> instead. Between 16.0 and 16.2, you can use a very simple polyfill for fragments.

Try the following

// Modern syntax >= React 16.2.0
const Test = ({stations}) => (
  <>
    {stations.map(station => (
      <div className="station" key={station.call}>{station.call}</div>
    ))}
  </>
); 

// Modern syntax < React 16.2.0
// You need to wrap in an extra element like div here

const Test = ({stations}) => (
  <div>
    {stations.map(station => (
      <div className="station" key={station.call}>{station.call}</div>
    ))}
  </div>
); 

// old syntax
var Test = React.createClass({
    render: function() {
        var stationComponents = this.props.stations.map(function(station) {
            return <div className="station" key={station.call}>{station.call}</div>;
        });
        return <div>{stationComponents}</div>;
    }
});

var stations = [
  {call:'station one',frequency:'000'},
  {call:'station two',frequency:'001'}
]; 

ReactDOM.render(
  <div>
    <Test stations={stations} />
  </div>,
  document.getElementById('container')
);

Don't forget the key attribute!

System.out.println(A.compareTo(B)>0?"Yes":"No")

if the value of A>B it will return "Yes" or "No".

You can't. Javascript runs client side, C# runs server side.

In fact, your server will run all the C# code, generating Javascript. The Javascript then, is run in the browser. As said in the comments, the compiler doesn't know Javascript.

To call the functionality on your server, you'll have to use techniques such as AJAX, as said in the other answers.

You could try nex approach css

 .map {
            height: 300px;
            width: 100%;
        }

HTML

@foreach(var map in maps)
{
  <div id="[email protected]" lat="@map.Latitude" lng="@map.Longitude" class="map">
  </div>
}

JavaScript

 <script>
    var maps = [];
    var markers = [];
    function initMap() {
        var $maps = $('.map');
        $.each($maps, function (i, value) {
            var uluru = { lat: parseFloat($(value).attr('lat')), lng: parseFloat($(value).attr('lng')) };

            var mapDivId = $(value).attr('id');

            maps[mapDivId] = new google.maps.Map(document.getElementById(mapDivId), {
                zoom: 17,
                center: uluru
            });

            markers[mapDivId] = new google.maps.Marker({
                position: uluru,
                map: maps[mapDivId]
            });
        })
    }
</script>

<script async defer

In my case it was gcc 6 the one missing

This is possible by defining a custom Builder in eclipse (see the link in Peter's answer). However, unless your project is very small, it may slow down your workspace unacceptably. Autobuild for class files happens incrementally, i.e. only those classes affected by a change are recompiled, but the JAR file will have to be rebuilt and copied completely, every time you save a change.

You only have to get the view of activity that carry this fragment and this could only happen when your fragment is already created

override the onViewCreated() method inside your fragment and enjoy its magic :) ..

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Button button = (Button) view.findViewById(R.id.YOURBUTTONID);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
         //place your action here
         }
    });

You can get the total number of rows containing a specific name using:

SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'

Given the count, you can now get the nth row using:

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1

Where 1 <= n <= COUNT(*) from the first query.

Example:

getting the 3rd row

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1

Swift 3.0

With Swift 3, the name of NSJSONSerialization and its methods have changed, according to the Swift API Design Guidelines.

let dic = ["2": "B", "1": "A", "3": "C"]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: dic, options: .prettyPrinted)
    // here "jsonData" is the dictionary encoded in JSON data

    let decoded = try JSONSerialization.jsonObject(with: jsonData, options: [])
    // here "decoded" is of type `Any`, decoded from JSON data

    // you can now cast it with the right type        
    if let dictFromJSON = decoded as? [String:String] {
        // use dictFromJSON
    }
} catch {
    print(error.localizedDescription)
}

Swift 2.x

do {
    let jsonData = try NSJSONSerialization.dataWithJSONObject(dic, options: NSJSONWritingOptions.PrettyPrinted)
    // here "jsonData" is the dictionary encoded in JSON data

    let decoded = try NSJSONSerialization.JSONObjectWithData(jsonData, options: [])
    // here "decoded" is of type `AnyObject`, decoded from JSON data

    // you can now cast it with the right type 
    if let dictFromJSON = decoded as? [String:String] {
        // use dictFromJSON
    }
} catch let error as NSError {
    print(error)
}

Swift 1

var error: NSError?
if let jsonData = NSJSONSerialization.dataWithJSONObject(dic, options: NSJSONWritingOptions.PrettyPrinted, error: &error) {
    if error != nil {
        println(error)
    } else {
        // here "jsonData" is the dictionary encoded in JSON data
    }
}

if let decoded = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error) as? [String:String] {
    if error != nil {
        println(error)
    } else {
        // here "decoded" is the dictionary decoded from JSON data
    }
}

Yes.

The new socket option allows multiple sockets on the same host to bind to the same port

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

// The following method would return you timestamp after converting to milliseconds. [RETURNS STRING]

- (NSString *) timeInMiliSeconds
{
    NSDate *date = [NSDate date];
    NSString * timeInMS = [NSString stringWithFormat:@"%lld", [@(floor([date timeIntervalSince1970] * 1000)) longLongValue]];
    return timeInMS;
}

$('#id option').remove();

This will clear the Drop Down list. if you want to clear to select value then $("#id option:selected").remove();

ALTER DATABASE name OWNER TO new_owner;

See the Postgresql manual's entry on this for more details.

If none the above work, then try this : Modify the LISTENER.ora (mine is found in : oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora) ==> add a custom listener that points to your database(SID), example my SID is XZ0301, so :

## Base XZ03001

SID_LIST_LISTENER_XZ03001=(SID_LIST=(SID_DESC=(ORACLE_HOME =
E:\oracle\product\11.2.0\dbhome_1)(SID_NAME= XZ03001)))

LISTENER_XZ03001=(DESCRIPTION_LIST=(ADDRESS=(PROTOCOL =
TCP)(HOST=MyComputerName)(PORT= 1521)))

DIAG_ADR_ENABLED_LISTENER_XZ03001=ON

ADR_BASE_LISTENER_XZ03001=E:\oracle

Restart your machine

For Windows 7, use the following to modify the LISTENER.ora: - Go to Start > All Programs > Accessories - Right click Notepad and then click Run as Administrator . - File>open and navigate to the tnsnames.ora file. - Make the changes then it should allow you to save

simply do this..

@Override
public void onBackPressed() {
    //super.onBackPressed();
}

commenting out the //super.onBackPressed(); will do the trick

So if i understood well, i would say that <pluginManagement> just like <dependencyManagement> are both used to share only the configuration between a parent and it's sub-modules.

For that we define the dependencie's and plugin's common configurations in the parent project and then we only have to declare the dependency/plugin in the sub-modules to use it, without having to define a configuration for it (i.e version or execution, goals, etc). Though this does not prevent us from overriding the configuration in the submodule.

In contrast <dependencies> and <plugins> are inherited along with their configurations and should not be redeclared in the sub-modules, otherwise a conflict would occur.

is that right ?

If the rest of your system is OK with DateTimeOffset instead of DateTime, there's a really convenient feature:

long unixSeconds = DateTimeOffset.Now.ToUnixTimeSeconds();
