Try the following code:

//...
By mySelector = By.xpath("/html/body/div[1]/div/section/div/div[2]/form[1]/div/ul/li");
List<WebElement> myElements = driver.findElements(mySelector);
for(WebElement e : myElements) {
  System.out.println(e.getText());
}

It will returns with the whole content of the <li> tags, like:

<a class="extra">Vše</a> (950)</li>

But you can easily get the number now from it, for example by using split() and/or substring().

super is a keyword. It is used inside a sub-class method definition to call a method defined in the superclass. Private methods of the superclass cannot be called. Only public and protected methods can be called by the super keyword. It is also used by class constructors to invoke constructors of its parent class.

Check here for further explanation.

Try...

$("#captureAudio").prop('checked', false); 

Open the "Maven Projects" tab/window and clicking the "Reimport All Maven Projects" in the upper left corner starts to reload all dependencies from their repositories. The status bar informs about the process.

What lets you think that this is not working correctly? Maybe any of the dependencies can't be load from the repository?

Make it serializable

// example error
let err = new Error('I errored')

// one liner converting Error into regular object that can be stringified
err = Object.getOwnPropertyNames(err).reduce((acc, key) => { acc[key] = err[key]; return acc; }, {})

If you want to send this object from child process, worker or though the network there's no need to stringify. It will be automatically stringified and parsed like any other normal object

You can do something that will look like static inheritance.

Here is the trick:

public abstract class StaticBase<TSuccessor>
    where TSuccessor : StaticBase<TSuccessor>, new()
{
    protected static readonly TSuccessor Instance = new TSuccessor();
}

Then you can do this:

public class Base : StaticBase<Base>
{
    public Base()
    {
    }

    public void MethodA()
    {
    }
}

public class Inherited : Base
{
    private Inherited()
    {
    }

    public new static void MethodA()
    {
        Instance.MethodA();
    }
}

The Inherited class is not static itself, but we don't allow to create it. It actually has inherited static constructor which builds Base, and all properties and methods of Base available as static. Now the only thing left to do make static wrappers for each method and property you need to expose to your static context.

There are downsides like the need for manual creation of static wrapper methods and new keyword. But this approach helps support something that is really similar to static inheritance.

P.S. We used this for creating compiled queries, and this actually can be replaced with ConcurrentDictionary, but a static read-only field with its thread safety was good enough.

As I understand it, "request timeout" means the ICMP packet reached from one host to the other host but the reply could not reach the requesting host. There may be more packet loss or some physical issue. "destination host unreachable" means there is no proper route defined between two hosts.

The standalone declaration is a way of telling the parser to ignore any markup declarations in the DTD. The DTD is thereafter used for validation only.

As an example, consider the humble <img> tag. If you look at the XHTML 1.0 DTD, you see a markup declaration telling the parser that <img> tags must be EMPTY and possess src and alt attributes. When a browser is going through an XHTML 1.0 document and finds an <img> tag, it should notice that the DTD requires src and alt attributes and add them if they are not present. It will also self-close the <img> tag since it is supposed to be EMPTY. This is what the XML specification means by "markup declarations can affect the content of the document." You can then use the standalone declaration to tell the parser to ignore these rules.

Whether or not your parser actually does this is another question, but a standards-compliant validating parser (like a browser) should.

Note that if you do not specify a DTD, then the standalone declaration "has no meaning," so there's no reason to use it unless you also specify a DTD.

One of my friends is writing a graphics app using NVIDIA CUDA. Application fits in very nicely with OOP paradigm and the problem can be decomposed into modules neatly. However, to use CUDA you need to use C, which doesn't support inheritance. Therefore, you need to be clever.

a) You devise a clever system which will emulate inheritance to a certain extent. It can be done!

i) You can use a hook system, which expects every child C of parent P to have a certain override for function F. You can make children register their overrides, which will be stored and called when required.

ii) You can use struct memory alignment feature to cast children into parents.

This can be neat but it's not easy to come up with future-proof, reliable solution. You will spend lots of time designing the system and there is no guarantee that you won't run into problems half-way through the project. Implementing multiple inheritance is even harder, if not almost impossible.

b) You can use consistent naming policy and use divide and conquer approach to create a program. It won't have any inheritance but because your functions are small, easy-to-understand and consistently formatted you don't need it. The amount of code you need to write goes up, it's very hard to stay focused and not succumb to easy solutions (hacks). However, this ninja way of coding is the C way of coding. Staying in balance between low-level freedom and writing good code. Good way to achieve this is to write prototypes using a functional language. For example, Haskell is extremely good for prototyping algorithms.

I tend towards approach b. I wrote a possible solution using approach a, and I will be honest, it felt very unnatural using that code.

 declare @date int
 WITH CTE_DatesTable
AS
(
  SELECT CAST('20000101' as date) AS [date]
  UNION ALL
  SELECT   DATEADD(dd, 1, [date])
  FROM CTE_DatesTable
  WHERE DATEADD(dd, 1, [date]) <= '21001231'
)
SELECT [DWDateKey]=[date],[DayDate]=datepart(dd,[date]),[DayOfWeekName]=datename(dw,[date]),[WeekNumber]=DATEPART( WEEK , [date]),[MonthNumber]=DATEPART( MONTH , [date]),[MonthName]=DATENAME( MONTH , [date]),[MonthShortName]=substring(LTRIM( DATENAME(MONTH,[date])),0, 4),[Year]=DATEPART(YY,[date]),[QuarterNumber]=DATENAME(quarter, [date]),[QuarterName]=DATENAME(quarter, [date]) into DimDate   FROM CTE_DatesTable

OPTION (MAXRECURSION 0);

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

Use python Sets when you need to compare hm... sets of data. Strings can be represented as sets of characters quite fast. Here I test if string is allowed phone number. First string is allowed, second not. Works fast and simple.

In [17]: timeit.Timer("allowed = set('0123456789+-() ');p = set('+7(898) 64-901-63 ');p.issubset(allowed)").timeit()

Out[17]: 0.8106249139964348

In [18]: timeit.Timer("allowed = set('0123456789+-() ');p = set('+7(950) 64-901-63 ???');p.issubset(allowed)").timeit()

Out[18]: 0.9240323599951807

Never use regexps if you can avoid them.

Actually, it is as simple as setting major and minor separately:

In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]

In [10]: yscale('log')

In [11]: grid(b=True, which='major', color='b', linestyle='-')

In [12]: grid(b=True, which='minor', color='r', linestyle='--')

The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log'), but it can also be done with plt.minorticks_on().

In entity framework, when object is added to context, its state changes to Added. EF also changes state of each object to added in object tree and hence you are either getting primary key violation error or duplicate records are added in table.

Not sure why an answer with Linux commands would get so many up votes for a Windows related question, but anyway...

If phpinfo() shows Curl as enabled, yet php -m does NOT, it means that you probably have a php-cli.ini too. run php -i and see which ini file loaded. If it's different, diff it and reflect and differences in the CLI ini file. Then you should be good to go.

Btw download and use Git Bash instead of cmd.exe!

The accepted answer is the correct command, I just want to add one additional thing, when extracting the key if you leave the PEM password("Enter PEM pass phrase:") blank then the complete key will not be extracted but only the localKeyID will be extracted. To get the complete key you must specify a PEM password whem running the following command.

Please note that when it comes to Import password, you can specify the actual password for "Enter Import Password:" or can leave this password blank:

openssl pkcs12 -in yourP12File.pfx -nocerts -out privateKey.pem

ECU = EC2 Compute Unit. More from here: http://aws.amazon.com/ec2/faqs/#What_is_an_EC2_Compute_Unit_and_why_did_you_introduce_it

Amazon EC2 uses a variety of measures to provide each instance with a consistent and predictable amount of CPU capacity. In order to make it easy for developers to compare CPU capacity between different instance types, we have defined an Amazon EC2 Compute Unit. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. We use several benchmarks and tests to manage the consistency and predictability of the performance from an EC2 Compute Unit. One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor. This is also the equivalent to an early-2006 1.7 GHz Xeon processor referenced in our original documentation. Over time, we may add or substitute measures that go into the definition of an EC2 Compute Unit, if we find metrics that will give you a clearer picture of compute capacity.

Get a handle to the root ThreadGroup, like this:

ThreadGroup rootGroup = Thread.currentThread().getThreadGroup();
ThreadGroup parentGroup;
while ((parentGroup = rootGroup.getParent()) != null) {
    rootGroup = parentGroup;
}

Now, call the enumerate() function on the root group repeatedly. The second argument lets you get all threads, recursively:

Thread[] threads = new Thread[rootGroup.activeCount()];
while (rootGroup.enumerate(threads, true ) == threads.length) {
    threads = new Thread[threads.length * 2];
}

Note how we call enumerate() repeatedly until the array is large enough to contain all entries.

<input type="text" id="input_id" />    

$('#input_id').keydown(function (event) {
    if (event.keyCode == 13) { 
         // Call your function here or add code here
    }
});

Specify the paths explicitly:

git diff HEAD:full/path/to/foo full/path/to/bar

Check out the --find-renames option in the git-diff docs.

As the other answers have indicated, you need to use an anonymous type.

As far as syntax is concerned, I personally far prefer method chaining. The method chaining equivalent would be:-

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo)
    .Select(x => new { x.EMAIL, x.ID });

AFAIK, the declarative LINQ syntax is converted to a method call chain similar to this when it is compiled.

UPDATE

If you want the entire object, then you just have to omit the call to Select(), i.e.

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo);

I am just wondering why to use some libraries for JWT token decoding and verification at all.

Encoded JWT token can be created using following pseudocode

var headers = base64URLencode(myHeaders);
var claims = base64URLencode(myClaims);
var payload = header + "." + claims;

var signature = base64URLencode(HMACSHA256(payload, secret));

var encodedJWT = payload + "." + signature;

It is very easy to do without any specific library. Using following code:

using System;
using System.Text;
using System.Security.Cryptography;

public class Program
{   
    // More info: https://stormpath.com/blog/jwt-the-right-way/
    public static void Main()
    {           
        var header = "{\"typ\":\"JWT\",\"alg\":\"HS256\"}";
        var claims = "{\"sub\":\"1047986\",\"email\":\"[email protected]\",\"given_name\":\"John\",\"family_name\":\"Doe\",\"primarysid\":\"b521a2af99bfdc65e04010ac1d046ff5\",\"iss\":\"http://example.com\",\"aud\":\"myapp\",\"exp\":1460555281,\"nbf\":1457963281}";

        var b64header = Convert.ToBase64String(Encoding.UTF8.GetBytes(header))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");
        var b64claims = Convert.ToBase64String(Encoding.UTF8.GetBytes(claims))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        var payload = b64header + "." + b64claims;
        Console.WriteLine("JWT without sig:    " + payload);

        byte[] key = Convert.FromBase64String("mPorwQB8kMDNQeeYO35KOrMMFn6rFVmbIohBphJPnp4=");
        byte[] message = Encoding.UTF8.GetBytes(payload);

        string sig = Convert.ToBase64String(HashHMAC(key, message))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        Console.WriteLine("JWT with signature: " + payload + "." + sig);        
    }

    private static byte[] HashHMAC(byte[] key, byte[] message)
    {
        var hash = new HMACSHA256(key);
        return hash.ComputeHash(message);
    }
}

The token decoding is reversed version of the code above.To verify the signature you will need to the same and compare signature part with calculated signature.

UPDATE: For those how are struggling how to do base64 urlsafe encoding/decoding please see another SO question, and also wiki and RFCs

I like to use find which is first assigned to variable and IFS switched to new line as follow:

FilesFound=$(find . -name "*.txt")

IFSbkp="$IFS"
IFS=$'\n'
counter=1;
for file in $FilesFound; do
    echo "${counter}: ${file}"
    let counter++;
done
IFS="$IFSbkp"

As commented by @Konrad Rudolph this will not work with "new lines" in file name. I still think it is handy as it covers most of the cases when you need to loop over command output.

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

        {
            charz.add(c);
            //System.out.print(c);
        }
    }

    for(Character c : charz)
    {
        System.out.print(c);

As of ASP.NET MVC 5.1, adding a class to an EditorFor is possible (the original question specified ASP.NET MVC 3, and the accepted answer is still the best with that considered).

@Html.EditorFor(x=> x.MyProperty,
    new { htmlAttributes = new { @class = "MyCssClass" } })

See: What's New in ASP.NET MVC 5.1, Bootstrap support for editor templates

This is equivalent.

l=[..., 1,2,3]
l=[Ellipsis, 1,2,3]

... is a constant defined inside built-in constants.

Ellipsis

The same as the ellipsis literal “...”. Special value used mostly in conjunction with extended slicing syntax for user-defined container data types.

this worked for me.

let content = 'Hello world';

static apicall(content) {
return axios({
  url: `url`,
  method: "put",
  data: content
 });
}

apicall()
.then((response) => {
   console.log("success",response.data)
}
.error( () => console.log('error'));

Chrome 58 has dropped support for certificates without Subject Alternative Names.

Moving forward, this might be another reason for you encountering this error.

Since Python evaluates also the data type NoneType as False during the check, a more precise answer is:

var = False
if var is False:
    print('learnt stuff')

This prevents potentially unwanted behaviour such as:

var = []  # or None
if not var:
    print('learnt stuff') # is printed what may or may not be wanted

But if you want to check all cases where var will be evaluated to False, then doing it by using logical not keyword is the right thing to do.

has_key is a dictionary method, but in will work on any collection, and even when __contains__ is missing, in will use any other method to iterate the collection to find out.

    def reset_parameters(self):
        init.kaiming_uniform_(self.weight, a=math.sqrt(3))
        if self.bias is not None:
            fan_in, _ = init._calculate_fan_in_and_fan_out(self.weight)
            bound = 1 / math.sqrt(fan_in)
            init.uniform_(self.bias, -bound, bound)

But I wanna point out that actually we know some assumptions in the paper of Kaiming He, Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification, are not appropriate, though it looks like the deliberately designed initialization method makes a hit in practice.

E.g., within the subsection of Backward Propagation Case, they assume that $w_l$ and $\delta y_l$ are independent of each other. But as we all known, take the score map $\delta y^L_i$ as an instance, it often is $y_i-softmax(y^L_i)=y_i-softmax(w^L_ix^L_i)$ if we use a typical cross entropy loss function objective.

So I think the true underlying reason why He's Initialization works well remains to unravel. Cuz everyone has witnessed its power on boosting deep learning training.

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings ? Display ? Animation) then the dialogs won't be animated no matter what you do!

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>
</resources>

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;

Try this:

sudo gem install cocoapods --user-install

Worked for me

If you have multiple projects, make sure you are not adding a dependency multiple times, I needed to exclude the other project's dependency like this:

compile(project(':OtherProject-SDK')) {
    compile.exclude module: 'play-services-gcm'
    compile.exclude module: 'play-services-location'
    compile.exclude module: 'support-v4'
    compile.exclude module: 'okhttp'
}

If you want to log errors from web-page, you should use WebChromeClient and override its onConsoleMessage:

webView.settings.apply {
    javaScriptEnabled = true
    javaScriptCanOpenWindowsAutomatically = true
    domStorageEnabled = true
}
webView.webViewClient = WebViewClient()
webView.webChromeClient = MyWebChromeClient()

private class MyWebChromeClient : WebChromeClient() {
    override fun onConsoleMessage(consoleMessage: ConsoleMessage): Boolean {
        Timber.d("${consoleMessage.message()}")
        Timber.d("${consoleMessage.lineNumber()} ${consoleMessage.sourceId()}")
        return super.onConsoleMessage(consoleMessage)
    }
}

You are getting that error because an application with a package name same as your application already exists. If you are sure that you have not installed the same application before, change the package name and try.

Else wise, here is what you can do:

1. Uninstall the application from the device: Go to Settings -> Manage Applications and choose Uninstall OR
2. Uninstall the app using adb command line interface: type adb uninstall After you are done with this step, try installing the application again.

A minor addition to the answers already posted: object files not compiled to be position independent are relocatable; they contain relocation table entries.

These entries allow the loader (that bit of code that loads a program into memory) to rewrite the absolute addresses to adjust for the actual load address in the virtual address space.

An operating system will try to share a single copy of a "shared object library" loaded into memory with all the programs that are linked to that same shared object library.

Since the code address space (unlike sections of the data space) need not be contiguous, and because most programs that link to a specific library have a fairly fixed library dependency tree, this succeeds most of the time. In those rare cases where there is a discrepancy, yes, it may be necessary to have two or more copies of a shared object library in memory.

Obviously, any attempt to randomize the load address of a library between programs and/or program instances (so as to reduce the possibility of creating an exploitable pattern) will make such cases common, not rare, so where a system has enabled this capability, one should make every attempt to compile all shared object libraries to be position independent.

Since calls into these libraries from the body of the main program will also be made relocatable, this makes it much less likely that a shared library will have to be copied.

You can't do that, unless you take the child out of the parent and place it via positioning.

The only way I know and it actually works, is to use a translucid image (.png with transparency) for the parent's background. The only disavantage is that you can't control the opacity via CSS, other than that it works!

Such lookups are implemented in django.views.generic.date_based as follows:

{'date_time_field__range': (datetime.datetime.combine(date, datetime.time.min),
                            datetime.datetime.combine(date, datetime.time.max))} 

Because it is quite verbose there are plans to improve the syntax using __date operator. Check "#9596 Comparing a DateTimeField to a date is too hard" for more details.

Regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. Hence you can see that regular grammar is a subset of context-free grammar.

So for a palindrome for instance, is of the form,

S->ABA
A->something
B->something

You can clearly see that palindromes cannot be expressed in regular grammar since it needs to be either right or left linear and as such cannot have a non-terminal on both side.

Since regular grammars are non-ambiguous, there is only one production rule for a given non-terminal, whereas there can be more than one in the case of a context-free grammar.

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

Since the border is used just for visual appearance, you could put it into the ListBoxItem's ControlTemplate and modify the properties there. In the ItemTemplate, you could place only the StackPanel and the TextBlock. In this way, the code also remains clean, as in the appearance of the control will be controlled via the ControlTemplate and the data to be shown will be controlled via the DataTemplate.

CSS selectors perform far better than Xpath and it is well documented in Selenium community. Here are some reasons,

• Xpath engines are different in each browser, hence make them inconsistent
• IE does not have a native xpath engine, therefore selenium injects its own xpath engine for compatibility of its API. Hence we lose the advantage of using native browser features that WebDriver inherently promotes.
• Xpath tend to become complex and hence make hard to read in my opinion

However there are some situations where, you need to use xpath, for example, searching for a parent element or searching element by its text (I wouldn't recommend the later).

You can read blog from Simon here . He also recommends CSS over Xpath.

If you are testing content then do not use selectors that are dependent on the content of the elements. That will be a maintenance nightmare for every locale. Try talking with developers and use techniques that they used to externalize the text in the application, like dictionaries or resource bundles etc. Here is my blog that explains it in detail.

Thanks to @parishodak, here is the link which provides the numbers proving that CSS performance is better

Python 3

Just write below lines that are easy to remember before writing your code:

import warnings

warnings.filterwarnings("ignore")

See Redirecting Output from a Running Process.

Firstly I run the command cat > foo1 in one session and test that data from stdin is copied to the file. Then in another session I redirect the output.

Firstly find the PID of the process:

$ ps aux | grep cat
rjc 6760 0.0 0.0 1580 376 pts/5 S+ 15:31 0:00 cat

Now check the file handles it has open:

$ ls -l /proc/6760/fd
total 3
lrwx—— 1 rjc rjc 64 Feb 27 15:32 0 -> /dev/pts/5
l-wx—— 1 rjc rjc 64 Feb 27 15:32 1 -> /tmp/foo1
lrwx—— 1 rjc rjc 64 Feb 27 15:32 2 -> /dev/pts/5

Now run GDB:

$ gdb -p 6760 /bin/cat
GNU gdb 6.4.90-debian

[license stuff snipped]

Attaching to program: /bin/cat, process 6760

[snip other stuff that's not interesting now]

(gdb) p close(1)
$1 = 0
(gdb) p creat("/tmp/foo3", 0600)
$2 = 1
(gdb) q
The program is running. Quit anyway (and detach it)? (y or n) y
Detaching from program: /bin/cat, process 6760

The p command in GDB will print the value of an expression, an expression can be a function to call, it can be a system call… So I execute a close() system call and pass file handle 1, then I execute a creat() system call to open a new file. The result of the creat() was 1 which means that it replaced the previous file handle. If I wanted to use the same file for stdout and stderr or if I wanted to replace a file handle with some other number then I would need to call the dup2() system call to achieve that result.

For this example I chose to use creat() instead of open() because there are fewer parameter. The C macros for the flags are not usable from GDB (it doesn’t use C headers) so I would have to read header files to discover this – it’s not that hard to do so but would take more time. Note that 0600 is the octal permission for the owner having read/write access and the group and others having no access. It would also work to use 0 for that parameter and run chmod on the file later on.

After that I verify the result:

ls -l /proc/6760/fd/
total 3
lrwx—— 1 rjc rjc 64 2008-02-27 15:32 0 -> /dev/pts/5
l-wx—— 1 rjc rjc 64 2008-02-27 15:32 1 -> /tmp/foo3 <====
lrwx—— 1 rjc rjc 64 2008-02-27 15:32 2 -> /dev/pts/5

Typing more data in to cat results in the file /tmp/foo3 being appended to.

If you want to close the original session you need to close all file handles for it, open a new device that can be the controlling tty, and then call setsid().

I was having the same problem with the AND() breaking the conditional formatting. I just happened to try treating the AND as multiplication, and it works! Remove the AND() function and just multiply your arguments. Excel will treat the booleans as 1 for true and 0 for false. I just tested this formula and it seems to work.

=(INDIRECT(ADDRESS(4,COLUMN()))>=INDIRECT(ADDRESS(ROW(),4)))*(INDIRECT(ADDRESS(4,COLUMN()))<=INDIRECT(ADDRESS(ROW(),5)))

It looks that you had done all setup properly but there might be one area where it might be causing problem

Check the value of your "CLASSPATH" variable and make sure at the end you kept ;.

Note: ; is for end separator . is for including existing path at the end

MyButton.setGravity(Gravity.RIGHT);

For layout_gravity use the answer stated by "karthi". This method sets gravity to place the children inside the view.

I realize the following suggestion doesn't answer your question, but the simplest method I have found to capture a rapidly-changing DirectX view, is to plug a video camera into the S-video port of the video card, and record the images as a movie. Then transfer the video from the camera back to an MPG, WMV, AVI etc. file on the computer.

For similar tasks, you can use sessionStorage to store data locally until the browser tab is closed.

The sessionStorage object stores data for only one session (the data is deleted when the browser tab is closed).(W3Schools)

This is my pen.

<div id="Notice">
    <span title="remove this until browser tab is closed"><u>dismiss</u>.</span>
</div>
<script>
    $("#Notice").click(function() {
     //set sessionStorage on click
        sessionStorage.setItem("dismissNotice", "Hello");
        $("#Notice").remove();
    });
    if (sessionStorage.getItem("dismissNotice"))
    //When sessionStorage is set Do stuff...
        $("#Notice").remove();
</script>

SERIOUS DISCLAIMER

This solution has a serious security flaw. Please use at your own risk.
Have a look at the comments on this post, and look at all the answers to this question.

OK, I had to go to the customer premises and found a solution. I:

• Exported the keystore that holds the signing keys in PKCS #12 format
• Opened control panel Java -> Security tab
• Clicked Manage certificates
• Imported this new keystore as a secure site CA

Then I opened the JAWS application without any warning. This is a little bit cumbersome, but much cheaper than buying a signed certificate!

I have tried other techniques, but none of them worked, also no error produced, but when I have used the code below, it worked for me.

((JavascriptExecutor)driver).executeScript("window.open()");
ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles());
driver.switchTo().window(tabs.get(1));
driver.get("http://google.com");

I need the collection length to decide whether I should render table <thead></thead>

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

As a side note, you can include the separators while splitting the string in Go. To do so, use strings.SplitAfter as in the example below.

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Printf("%q\n", strings.SplitAfter("z,o,r,r,o", ","))
}

SELECT2 < V4

Step #1: HTML

<input name="mySelect2" type="hidden" id="mySelect2">

Step #2: Create an instance of Select2

$("#mySelect2").select2({
      placeholder: "My Select 2",
      multiple: false,
      minimumInputLength: 1,
      ajax: {
          url: "/elements/all",
          dataType: 'json',
          quietMillis: 250,
          data: function(term, page) {
              return {
                  q: term,
              };
          },
          results: function(data, page) {
              return {results: data};
          },
          cache: true
      },
      formatResult: function(element){
          return element.text + ' (' + element.id + ')';
      },
      formatSelection: function(element){
          return element.text + ' (' + element.id + ')';
      },
      escapeMarkup: function(m) {
          return m;
      }
});

Step #3: Set your desired value

$("#mySelect2").select2('data', { id:"elementID", text: "Hello!"});

If you use select2 without AJAX you can do as follow:

<select name="mySelect2" id="mySelect2">
  <option value="0">One</option>
  <option value="1">Two</option>
  <option value="2">Three</option>
</select>

/* "One" will be the selected option */
$('[name=mySelect2]').val("0");

You can also do so:

$("#mySelect2").select2("val", "0");

SELECT2 V4

For select2 v4 you can append directly an option/s as follow:

<select id="myMultipleSelect2" multiple="" name="myMultipleSelect2[]">
    <option value="TheID" selected="selected">The text</option>                                                                   
</select>

Or with JQuery:

var $newOption = $("<option selected='selected'></option>").val("TheID").text("The text")
 
$("#myMultipleSelect2").append($newOption).trigger('change');

other example

$("#myMultipleSelect2").val(5).trigger('change');

I think this is the simplest way:

<select onchange="if (this.value) window.location.href=this.value">
    <option value="">Pick one:</option>
    <option value="/foo">Foo</option>
    <option value="/bar">Bar</option>
</select>

I would use this in HTML 5... Just sayin

#footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 60px;
  background-color: #f5f5f5;
}

This should help :

https://www.w3schools.com/tags/att_select_required.asp

 <form>_x000D_
 <select required>_x000D_
  <option value="">None</option>_x000D_
  <option value="volvo">Volvo</option>_x000D_

  <option value="mercedes">Mercedes</option>_x000D_

Great question, and it's odd that the Swing toolkit doesn't include this functionality natively for JTextFields. But, here's a great answer from my Udemy.com course "Learn Java Like a Kid":

txtGuess = new JTextField();
txtGuess.addKeyListener(new KeyAdapter() {
    public void keyTyped(KeyEvent e) { 
        if (txtGuess.getText().length() >= 3 ) // limit textfield to 3 characters
            e.consume(); 
    }  
});

This limits the number of characters in a guessing game text field to 3 characters, by overriding the keyTyped event and checking to see if the textfield already has 3 characters - if so, you're "consuming" the key event (e) so that it doesn't get processed like normal.

In order to get the values of each variable, you need to treat the function as you would an array:

function data() {
    $a = "abc";
    $b = "def";
    $c = "ghi";
    return array($a, $b, $c);
}

// Assign a variable to the array; 
// I selected $dataArray (could be any name).

$dataArray = data();
list($a, $b, $c) = $dataArray;
echo $a . " ". $b . " " . $c;

//if you just need 1 variable out of 3;
list(, $b, ) = $dataArray;
echo $b;

How about this?

>>> tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]
>>> [x for x, y in enumerate(tuple_list) if y[1] == 7]
[1]
>>> [x for x, y in enumerate(tuple_list) if y[0] == 'kumquat']
[2]

As pointed out in the comments, this would get all matches. To just get the first one, you can do:

>>> [y[0] for y in tuple_list].index('kumquat')
2

There is a good discussion in the comments as to the speed difference between all the solutions posted. I may be a little biased but I would personally stick to a one-liner as the speed we're talking about is pretty insignificant versus creating functions and importing modules for this problem, but if you are planning on doing this to a very large amount of elements you might want to look at the other answers provided, as they are faster than what I provided.

I use approach with appending "singleton" link for element you want to show in fancybox. This is code, what I use with some minor edits:

function showElementInPopUp(elementId) {
    var fancyboxAnchorElementId = "fancyboxTriggerFor_" + elementId;
    if ($("#"+fancyboxAnchorElementId).length == 0) {
        $("body").append("<a id='" + fancyboxAnchorElementId + "' href='#" + elementId+ "' style='display:none;'></a>");
        $("#"+fancyboxAnchorElementId).fancybox();
    }

    $("#" + fancyboxAnchorElementId).click();
}

Additional explanation: If you show fancybox with "content" option, it will duplicate DOM, which is inside elements. Sometimes this is not OK. In my case I needed to have the same elements, because they were used in form.

If you are on both sides of the communication you can use repr() and eval() functions along with json.

import datetime, json

dt = datetime.datetime.now()
print("This is now: {}".format(dt))

dt1 = json.dumps(repr(dt))
print("This is serialised: {}".format(dt1))

dt2 = json.loads(dt1)
print("This is loaded back from json: {}".format(dt2))

dt3 = eval(dt2)
print("This is the same object as we started: {}".format(dt3))

print("Check if they are equal: {}".format(dt == dt3))

You shouldn't import datetime as

from datetime import datetime

since eval will complain. Or you can pass datetime as a parameter to eval. In any case this should work.

Java 8

well doing this in java 8 is so much fun and easier

Collections.sort(variants,(a,b)->a.compareTo(b));
Collections.reverse(variants);

Lambda expressions rock here!!!

in case you needed a more than one line logic for comparing a and b you could write it like this

Collections.sort(variants,(a,b)->{
    int result = a.compareTo(b);
    return result;
});

As per the javadoc for get(), it is the synonym for Navigate.to()

View javadoc screenshot below:

Javadoc for get() says it all -

Load a new web page in the current browser window. This is done using an HTTP GET operation, and the method will block until the load is complete. This will follow redirects issued either by the server or as a meta-redirect from within the returned HTML. Should a meta-redirect "rest" for any duration of time, it is best to wait until this timeout is over, since should the underlying page change whilst your test is executing the results of future calls against this interface will be against the freshly loaded page. Synonym for org.openqa.selenium.WebDriver.Navigation.to(String).

You need to put the arguments to pass ("/select etc") in the second parameter of the Start method.

Make sure you aren't trying to use the same User object more than once while changing the ID. In other words, if you were doing something in a batch type operation:

User user = new User();  // Using the same one over and over, won't work
List<Customer> customers = fetchCustomersFromSomeService();
for(Customer customer : customers) {
 // User user = new User(); <-- This would work, you get a new one each time
 user.setId(customer.getId());
 user.setName(customer.getName());
 saveUserToDB(user);
}

I prefer to use something like this:

window.callbackClass['newFunctionName'] = function(data) { console.log(data) };
...
window.callbackClass['newFunctionName'](data);

Although @yanick-rochon answer is correct, the simplest way to achieve your goal (if it's to serve a dynamically generated html) is:

var http = require('http');
http.createServer(function (req, res) {
  res.write('<html><head></head><body>');
  res.write('<p>Write your HTML content here</p>');

Yes, it is possible to assign inside if conditional check. But, your variable should have already been declared to assign something.

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

System.currentTimeMillis() does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date instance to a string before using it. You can use DateFormats to convert Dates to Strings in any timezone:

DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());

Also see this related question.

this.$router.go() does exactly this; if no arguments are specified, the router navigates to current location, refreshing the page.

_{note: current implementation of router and its history components don't mark the param as optional, but IMVHO it's either a bug or an omission on Evan You's part, since the spec explicitly allows it. I've filed an issue report about it. If you're really concerned with current TS annotations, just use the equivalent this.$router.go(0)}

As to 'why is it so': go internally passes its arguments to window.history.go, so its equal to windows.history.go() - which, in turn, reloads the page, as per MDN doc.

_{note: since this executes a "soft" reload on regular desktop (non-portable) Firefox, a bunch of strange quirks may appear if you use it but in fact you require a true reload; using the window.location.reload(true); (https://developer.mozilla.org/en-US/docs/Web/API/Location/reload) mentioned by OP instead may help - it certainly did solve my problems on FF.}

If no calculations are necessary after every row, it's much quicker to add rows in python, then convert to numpy. Here are timing tests using python 3.6 vs. numpy 1.14, adding 100 rows, one at a time:

import numpy as np 
from time import perf_counter, sleep

def time_it():
    # Compare performance of two methods for adding rows to numpy array
    py_array = [[0, 1, 2], [0, 2, 0]]
    py_row = [4, 5, 6]
    numpy_array = np.array(py_array)
    numpy_row = np.array([4,5,6])
    n_loops = 100

    start_clock = perf_counter()
    for count in range(0, n_loops):
       numpy_array = np.vstack([numpy_array, numpy_row]) # 5.8 micros
    duration = perf_counter() - start_clock
    print('numpy 1.14 takes {:.3f} micros per row'.format(duration * 1e6 / n_loops))

    start_clock = perf_counter()
    for count in range(0, n_loops):
        py_array.append(py_row) # .15 micros
    numpy_array = np.array(py_array) # 43.9 micros       
    duration = perf_counter() - start_clock
    print('python 3.6 takes {:.3f} micros per row'.format(duration * 1e6 / n_loops))
    sleep(15)

#time_it() prints:

numpy 1.14 takes 5.971 micros per row
python 3.6 takes 0.694 micros per row

So, the simple solution to the original question, from seven years ago, is to use vstack() to add a new row after converting the row to a numpy array. But a more realistic solution should consider vstack's poor performance under those circumstances. If you don't need to run data analysis on the array after every addition, it is better to buffer the new rows to a python list of rows (a list of lists, really), and add them as a group to the numpy array using vstack() before doing any data analysis.

This code strip all event listeners

var old_element=document.getElementsByClassName(".update-cart");    
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);  

Adding;

display: inline-block;

to the child elements will prevent them being split between columns.

I have a similar problem, but now I know the reason.

After we use git init, we should add a remote repository using

git remote add name url

Pay attention to the word name, if we change it to origin, then this problem will not happen.

Of course, if we change it to py, then using git pull py branch and git push py branch every time you pull and push something will also be OK.

During runtime your application is unable to find the jar.

Taken from this answer by Jared:

It is important to keep two different exceptions straight in our head in this case:

1. java.lang.ClassNotFoundException This an Exception, it indicates that the class was not found on the classpath. This indicates that we were trying to load the class definition, and the class did not exist on the classpath.

2. java.lang.NoClassDefFoundError This is Error, it indicates that the JVM looked in its internal class definition data structure for the definition of a class and did not find it. This is different than saying that it could not be loaded from the classpath. Usually this indicates that we previously attempted to load a class from the classpath, but it failed for some reason - now we're trying again, but we're not even going to try to load it, because we failed loading it earlier. The earlier failure could be a ClassNotFoundException or an ExceptionInInitializerError (indicating a failure in the static initialization block) or any number of other problems. The point is, a NoClassDefFoundError is not necessarily a classpath problem.

for similarities and differences

If I properly understood your question, supposing your running script is

/relative/path/to/script/index.php

This would give you the parent directory of your running script relative to the document www:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_NAME'])) . '/';
//$parent_dir will be '/relative/path/to/'

If you want the parent directory of your running script relative to server root:

$parent_dir = dirname(dirname($_SERVER['SCRIPT_FILENAME'])) . '/';
//$parent_dir will be '/root/some/path/relative/path/to/'

Maybe the simplest way is:

gmdate('H:i:s', $your_time_in_seconds);

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

    step ([
        $class: 'CopyArtifact',
        projectName: projectName,

This solves the problem.

Try this:

 $(function () {
     $('#row_dim').hide(); // this line you can avoid by adding #row_dim{display:none;} in your CSS
     $('#type').change(function () {
         $('#row_dim').hide();
         if (this.options[this.selectedIndex].value == 'parcel') {
             $('#row_dim').show();
         }
     });
 });

I figured out why the portrait view wasn't totally filling the viewport. At least in my case, it was because the scrollbar was always showing. In addition to the viewport code above, try adding this:

    browser.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    browser.setScrollbarFadingEnabled(false);

This causes the scrollbar to not take up layout space, and allows the webpage to fill the viewport.

Hope this helps

Before applying WORKDIR. Here the WORKDIR is at the wrong place and is not used wisely.

FROM microsoft/aspnetcore:2
COPY --from=build-env /publish /publish
WORKDIR /publish
ENTRYPOINT ["dotnet", "/publish/api.dll"]

We corrected the above code to put WORKDIR at the right location and optimised the following statements by removing /Publish

FROM microsoft/aspnetcore:2
WORKDIR /publish
COPY --from=build-env /publish .
ENTRYPOINT ["dotnet", "api.dll"]

So it acts like a cd and sets the tone for the upcoming statements.

There's another layout manager that may be of interest here: Overlay Layout Here's a simple tutorial: OverlayLayout: for layout management of components that lie on top of one another. Overlay Layout allows you to position panels on top of one another, and set a layout inside each panel. You are also able to set size and position of each panel separately.

(The reason I'm answering this question from years ago is because I have stumbled upon the same problem, and I have seen very few mentions of the Overlay Layout on StackOverflow, while it seems to be pretty well documented. Hopefully this may help someone else who keeps searching for it.)

Fixed-length arrays are not yet supported. What does that actually mean? Not that you can't create an array of n many things — obviously you can just do let a = [ 1, 2, 3 ] to get an array of three Ints. It means simply that array size is not something that you can declare as type information.

If you want an array of nils, you'll first need an array of an optional type — [SKSpriteNode?], not [SKSpriteNode] — if you declare a variable of non-optional type, whether it's an array or a single value, it cannot be nil. (Also note that [SKSpriteNode?] is different from [SKSpriteNode]?... you want an array of optionals, not an optional array.)

Swift is very explicit by design about requiring that variables be initialized, because assumptions about the content of uninitialized references are one of the ways that programs in C (and some other languages) can become buggy. So, you need to explicitly ask for an [SKSpriteNode?] array that contains 64 nils:

var sprites = [SKSpriteNode?](repeating: nil, count: 64)

This actually returns a [SKSpriteNode?]?, though: an optional array of optional sprites. (A bit odd, since init(count:,repeatedValue:) shouldn't be able to return nil.) To work with the array, you'll need to unwrap it. There's a few ways to do that, but in this case I'd favor optional binding syntax:

if var sprites = [SKSpriteNode?](repeating: nil, count: 64){
    sprites[0] = pawnSprite
}

Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.

If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.

If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("#el").offset().top - $(document).scrollTop()

If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

public class MapLocationActivity extends AppCompatActivity
        implements OnMapReadyCallback,
        GoogleApiClient.ConnectionCallbacks,

Result:

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

Unfortunately I found out that

var mydate = new Date('2014-04-03');_x000D_
console.log(mydate.toDateString());

returns "Wed Apr 02 2014". I know it sounds crazy, but it happens for some users.

The bulletproof solution is the following:

var parts ='2014-04-03'.split('-');_x000D_
// Please pay attention to the month (parts[1]); JavaScript counts months from 0:_x000D_
// January - 0, February - 1, etc._x000D_
var mydate = new Date(parts[0], parts[1] - 1, parts[2]); _x000D_
console.log(mydate.toDateString());

HTML

<div id="myparent">
  <div id="mychild">Test Content here</div>
</div>

CSS

#myparent {
  display: table;
}
#mychild {
  display: table-cell;
  vertical-align: middle;
}

We set the parent div to display as a table and the child div to display as a table-cell. We can then use vertical-align on the child div and set its value to middle. Anything inside this child div will be vertically centered.

You can first find the position of the string in this case ":"

'position = InStr(StringToSearch, StringToFind)
position = InStr(StringToSearch, ":")

Then use Left(StringToCut, NumberOfCharacterToCut)

Result = Left(StringToSearch, position -1)

I'll try to answer the why question: The Java array is very simple and rudimentary compared to classes like ArrayList, that are more dynamic. Java wants to know at declaration time how much memory should be allocated for the array. An ArrayList is much more dynamic and the size of it can vary over time.

If you initialize your array with the length of two, and later on it turns out you need a length of three, you have to throw away what you've got, and create a whole new array. Therefore the 'new' keyword.

In your first two examples, you tell at declaration time how much memory to allocate. In your third example, the array name becomes a pointer to nothing at all, and therefore, when it's initialized, you have to explicitly create a new array to allocate the right amount of memory.

I would say that (and if someone knows better, please correct me) the first example

AClass[] array = {object1, object2}

actually means

AClass[] array = new AClass[]{object1, object2};

but what the Java designers did, was to make quicker way to write it if you create the array at declaration time.

The suggested workarounds are good. If the time or memory usage is critical at runtime, use arrays. If it's not critical, and you want code that is easier to understand and to work with, use ArrayList.

You can simply detect the current local format and can get the date in your format, for example:

::for 30.10.2016 dd.MM.yyyy
if %date:~2,1%==. set d=%date:~-4%%date:~3,2%%date:~,2%
::for 10/30/2016 MM/dd/yyyy
if %date:~2,1%==/ set d=%date:~-4%%date:~,2%%date:~3,2%
::for 2016-10-30 yyyy-MM-dd
if %date:~4,1%==- set d=%date:~,4%%date:~5,2%%date:~-2%
::variable %d% have now value: 2016103 (yyyyMMdd)
set t=%time::=%
set t=%t:,=%
::variable %t% have now time without delimiters
cp source.log %d%_%t%.log

If you do not care about the data in management database; i.e. users, vhosts, messages etc., and neither about other queues, then you can reset via commandline by running the following commands in order:

WARNING: In addition to the queues, this will also remove any users and vhosts, you have configured on your RabbitMQ server; and will delete any persistent messages

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

The rabbitmq documentation says that the reset command:

Returns a RabbitMQ node to its virgin state.

Removes the node from any cluster it belongs to, removes all data from the management database, such as configured users and vhosts, and deletes all persistent messages.

So, be careful using it.

just write in your Custom ArrayAdaper this code:

public void swapItems(ArrayList<Item> arrayList) {
    this.clear();
    this.addAll(arrayList);
}

Not Obvious, But Fast

f, u = pd.factorize(df.name.values)
counts = np.bincount(f)
u[counts == counts.max()]

array(['alex', 'helen'], dtype=object)

With jquery you could do to sth. like this, which will simply switch classes.

$('.showhide').click(function() {
    $(this).removeClass('myclass');
    $(this).addClass('showhidenew');
});

If you want to switch classes back and forth on each click, you can use toggleClass, like so:

$('.showhide').click(function() {
    $(this).toggleClass('myclass');
    $(this).toggleClass('showhidenew');
});

Maintain a set and remove a randomly picked-up element (with choice) until the list is empty:

s = set(range(1, 6))
import random

while len(s) > 0:
  s.remove(random.choice(list(s)))
  print(s)

Three runs give three different answers:

>>>
set([1, 3, 4, 5])
set([3, 4, 5])
set([3, 4])
set([4])
set([])
>>>
set([1, 2, 3, 5])
set([2, 3, 5])
set([2, 3])
set([2])
set([])

>>>
set([1, 2, 3, 5])
set([1, 2, 3])
set([1, 2])
set([1])
set([])

You can also try

  Calendar calendar = Calendar.getInstance();
  System.out.println(calendar.getTimeInMillis());

getTimeInMillis() - the current time as UTC milliseconds from the epoch

Long time no Perl

while(<STDIN>) {
    next unless /:\s*(\S+)\s+\(([^\)]+)\)\s*(\*?)/;
    print "|$1|$2|$3|\n";
}

If you're using the PageFactory pattern or already have a reference to your WebElement, then you probably want to set the attribute, using your existing reference to the WebElement. (Rather than doing a document.getElementById(...) in your javascript)

The following sample allows you to set the attribute, using your existing WebElement reference.

Code Snippet

import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.FindBy;

public class QuickTest {

    RemoteWebDriver driver;

    @FindBy(id = "foo")
    private WebElement username;

    public void exampleUsage(RemoteWebDriver driver) {
        setAttribute(username, "attr", "10");
        setAttribute(username, "value", "bar");
    }

    public void setAttribute(WebElement element, String attName, String attValue) {
        driver.executeScript("arguments[0].setAttribute(arguments[1], arguments[2]);", 
                element, attName, attValue);
    }
}

This problem usually occurs when some process such as loading huge data to memory stream and your system memory is not capable of storing so much of data. Try clearing temp folder by giving the command

start -> run -> %temp%

Add the following Sub:

Sub SyncShell(ByVal Cmd As String, ByVal WindowStyle As VbAppWinStyle)
VBA.CreateObject("WScript.Shell").Run Cmd, WindowStyle, True
End Sub

If you add a reference to C:\Windows\system32\wshom.ocx you can also use:

Sub SyncShell(ByVal Cmd As String, ByVal WindowStyle As VbAppWinStyle)
Static wsh As New WshShell
wsh.Run Cmd, WindowStyle, True
End Sub

This version should be more efficient.

@Imran answer works for textboxes

for applying the datepicker to a div use this:

$('#div_id').attr("data-date", '1 January 2017');
$('#div_id').datepicker("update");

comma-delim multiple dates:

$('#div_id').attr("data-date", '1 January 2017,2 January 2017,3 January 2017');

Full thanks must go to Felix Kling for his excellent answer which I have gratefully used in my code. I offer a small enhancement of a boolean return value to report success or failure:

function recurse_copy($src, $dst) {

  $dir = opendir($src);
  $result = ($dir === false ? false : true);

  if ($result !== false) {
    $result = @mkdir($dst);

    if ($result === true) {
      while(false !== ( $file = readdir($dir)) ) { 
        if (( $file != '.' ) && ( $file != '..' ) && $result) { 
          if ( is_dir($src . '/' . $file) ) { 
            $result = recurse_copy($src . '/' . $file,$dst . '/' . $file); 
          }     else { 
            $result = copy($src . '/' . $file,$dst . '/' . $file); 
          } 
        } 
      } 
      closedir($dir);
    }
  }

  return $result;
}

Do the following thing if you want to use json as a http request and response. So we need to make changes in [context].xml

<!-- Configure to plugin JSON as request and response in method handler -->
<beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <beans:property name="messageConverters">
        <beans:list>
            <beans:ref bean="jsonMessageConverter"/>
        </beans:list>
    </beans:property>
</beans:bean>
<!-- Configure bean to convert JSON to POJO and vice versa -->
<beans:bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</beans:bean>   

MappingJackson2HttpMessageConverter to the RequestMappingHandlerAdapter messageConverters so that Jackson API kicks in and converts JSON to Java Beans and vice versa. By having this configuration, we will be using JSON in request body and we will receive JSON data in the response.

I am also providing small code snippet for controller part:

    @RequestMapping(value = EmpRestURIConstants.DUMMY_EMP, method = RequestMethod.GET)

    public @ResponseBody Employee getDummyEmployee() {
    logger.info("Start getDummyEmployee");
    Employee emp = new Employee();
    emp.setId(9999);
    emp.setName("Dummy");
    emp.setCreatedDate(new Date());
    empData.put(9999, emp);
    return emp;
}

So in above code emp object will directly convert into json as a response. same will happen for post also.

R has gotten to the point where the OS cannot allocate it another 75.1Mb chunk of RAM. That is the size of memory chunk required to do the next sub-operation. It is not a statement about the amount of contiguous RAM required to complete the entire process. By this point, all your available RAM is exhausted but you need more memory to continue and the OS is unable to make more RAM available to R.

Potential solutions to this are manifold. The obvious one is get hold of a 64-bit machine with more RAM. I forget the details but IIRC on 32-bit Windows, any single process can only use a limited amount of RAM (2GB?) and regardless Windows will retain a chunk of memory for itself, so the RAM available to R will be somewhat less than the 3.4Gb you have. On 64-bit Windows R will be able to use more RAM and the maximum amount of RAM you can fit/install will be increased.

If that is not possible, then consider an alternative approach; perhaps do your simulations in batches with the n per batch much smaller than N. That way you can draw a much smaller number of simulations, do whatever you wanted, collect results, then repeat this process until you have done sufficient simulations. You don't show what N is, but I suspect it is big, so try smaller N a number of times to give you N over-all.

from functools import reduce #python 3

>>> l = [[1,2,3],[4,5,6], [7], [8,9]]
>>> reduce(lambda x,y: x+y,l)
[1, 2, 3, 4, 5, 6, 7, 8, 9]

The extend() method in your example modifies x instead of returning a useful value (which reduce() expects).

A faster way to do the reduce version would be

>>> import operator
>>> l = [[1,2,3],[4,5,6], [7], [8,9]]

I'm not a mod_rewrite expert, I often struggle with it, but I have done this on one of my sites, it might need other flags etc depending on your circumstances. I'm using this:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteCond %{REQUEST_URI} !^/subdomains/subdomain
RewriteRule ^(.*)$ /subdomains/subdomain/$1 [L] 

Any other rewrite rules for the rest of the site must go afterwards to prevent them from interfering with your subdomain rewrites.

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

var otherInput = $(this).closest('.row').find('.inputQty');

That goes up to a row level, then back down to .inputQty.

Thank you so much to @Code in another answer. I can read any JSON file thanks to your code. Now, I'm trying to organize all the elements by levels, for could use them!

I was working with Android reading a JSON from an URL and the only I had to change was the lines

Set<Object> set = jsonObject.keySet(); Iterator<Object> iterator = set.iterator();

for

Iterator<?> iterator = jsonObject.keys();

I share my implementation, to help someone:

public void parseJson(JSONObject jsonObject) throws ParseException, JSONException {

    Iterator<?> iterator = jsonObject.keys();
    while (iterator.hasNext()) {
        String obj = iterator.next().toString();

        if (jsonObject.get(obj) instanceof JSONArray) {
            //Toast.makeText(MainActivity.this, "Objeto: JSONArray", Toast.LENGTH_SHORT).show();
            //System.out.println(obj.toString());
            TextView txtView = new TextView(this);
            txtView.setText(obj.toString());
            layoutIzq.addView(txtView);
            getArray(jsonObject.get(obj));
        } else {
            if (jsonObject.get(obj) instanceof JSONObject) {
                //Toast.makeText(MainActivity.this, "Objeto: JSONObject", Toast.LENGTH_SHORT).show();
                parseJson((JSONObject) jsonObject.get(obj));
            } else {
                //Toast.makeText(MainActivity.this, "Objeto: Value", Toast.LENGTH_SHORT).show();
                //System.out.println(obj.toString() + "\t"+ jsonObject.get(obj));
                TextView txtView = new TextView(this);
                txtView.setText(obj.toString() + "\t"+ jsonObject.get(obj));
                layoutIzq.addView(txtView);
            }
        }
    }
}

This error can also occur if the environment variable PGDATABASE is set to the name of a database that does not exist.

On OSX, I saw the following error while trying to launch psql from the Postgress.app menu:

psql: FATAL: database "otherdb" does not exist

The solution to the error was to remove export PGDATABASE=otherdb from ~/.bash_profile:

Further, if PGUSER is set to something other than your username, the following error will occur:

psql: FATAL: role "note" does not exist

The solution is to remove export PGUSER=notme from ~/.bash_profile.

awk '/inet addr:/{gsub(/^.{5}/,"",$2); print $2}' file
192.168.1.103

You will need a little JavaScript for that:

var list = document.getElementsByClassName('thumb');

for (var i = 0; i < list.length; i++) {
  var src = list[i].getAttribute('data-image-src');
  list[i].style.backgroundImage="url('" + src + "')";
}

Wrap that in <script> tags at the bottom just before the </body> tag or wrap in a function that you call once the page loaded.

1. Create an external table
2. Insert data into the table
3. Optional drop the table later, which wont delete that file since it is an external table

Example:

Creating external table to store the query results at '/user/myName/projectA_additionaData/'

CREATE EXTERNAL TABLE additionaData
(
     ID INT,
     latitude STRING,
     longitude STRING
)
COMMENT 'Additional Data gathered by joining of the identified cities with latitude and longitude data' 
ROW FORMAT DELIMITED FIELDS
TERMINATED BY ',' STORED AS TEXTFILE location '/user/myName/projectA_additionaData/';

Feeding the query results into the temp table

 insert into additionaData 
     Select T.ID, C.latitude, C.longitude 
     from TWITER  
     join CITY C on (T.location_name = C.location);

Dropping the temp table

drop table additionaData

I think you meant print test.sorted_word_list instead of print test.sort_word_list.

In addition list.sort() sorts a list in place and returns None, so you probably want to change sort_word_list() to do the following:

self.sorted_word_list = sorted(self.word_list)

You should also consider either renaming your num_words() function, or changing the attribute that the function assigns to, because currently you overwrite the function with an integer on the first call.

where returns ActiveRecord::Relation

Now take a look at find_by implementation:

def find_by
  where(*args).take
end

As you can see find_by is the same as where but it returns only one record. This method should be used for getting 1 record and where should be used for getting all records with some conditions.

You can set the default search_path at the database level:

ALTER DATABASE <database_name> SET search_path TO schema1,schema2;

Or at the user or role level:

ALTER ROLE <role_name> SET search_path TO schema1,schema2;

Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.

When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name> to create your databases.

Update Angular CLI for a workspace (Local)

npm install --save -dev @angular/cli@latest

Note: Make sure to install the global version using the command with ‘-g’ is if it installed properly.

npm install -g @angular/cli@latest

Run Update command to get a list of all dependencies required to be upgraded

ng update

Next Run update command as below for each individual Angular core package

ng update @angular/cli @angular/core

However, I had to add ‘–force’ and ‘–allow-dirty’ flags command additionally to fix all other pending issues.

ng update @angular/cli @angular/core --allow-dirty --force

One CSRF token is assigned to every session ( i.e. every time you log in). So before you wish to get some data entered by user and send that as ajax call to some function which is protected by csrf_protect decorator, try to find the functions that are being called before you are getting this data from user. E.g. some template must be being rendered on which your user is entering data. That template is being rendered by some function. In this function you can get csrf token as follows: csrf = request.COOKIES['csrftoken'] Now pass this csrf value in context dictionary against which template in question is being rendered. Now in that template write this line: Now in your javascript function, before making ajax request, write this: var csrf = $('#csrf').val() this will pick value of token passed to template and store it in variable csrf. Now while making ajax call, in your post data, pass this value as well : "csrfmiddlewaretoken": csrf

This will work even if you are not implementing django forms.

In fact, logic over here is : You need token which you can get from request. So you just need to figure out the function being called immediately after log in. Once you have this token, either make another ajax call to get it or pass it to some template which is accessible by your ajax.

File.Create(string) returns an instance of the FileStream class. You can call the Stream.Close() method on this object in order to close it and release resources that it's using:

var myFile = File.Create(myPath);
myFile.Close();

However, since FileStream implements IDisposable, you can take advantage of the using statement (generally the preferred way of handling a situation like this). This will ensure that the stream is closed and disposed of properly when you're done with it:

using (var myFile = File.Create(myPath))
{
   // interact with myFile here, it will be disposed automatically
}

Here:

df = df.reset_index()
df.columns[0] = 'New_ID'
df['New_ID'] = df.index + 880

It is just:

float f = (float)6;

Fatal errors or recoverable fatal errors now throw instances of Error in PHP 7 or higher versions. Like any other exceptions, Error objects can be caught using a try/catch block.

Example:

<?php
$variable = 'not an object';

try {
    $variable->method(); // Throws an Error object in PHP 7 or higger.
} catch (Error $e) {
    // Handle error
    echo $e->getMessage(); // Call to a member function method() on string
}

https://3v4l.org/67vbk

Or you can use Throwable interface to catch all exceptions.

Example:

<?php
    try {
        undefinedFunctionCall();
    } catch (Throwable $e) {
        // Handle error
        echo $e->getMessage(); // Call to undefined function undefinedFunctionCall()
    }

git branch --set-upstream <remote-branch>

sets the default remote branch for the current local branch.

Any future git pull command (with the current local branch checked-out),
will attempt to bring in commits from the <remote-branch> into the current local branch.

One way to avoid having to explicitly type --set-upstream is to use its shorthand flag -u as follows:

git push -u origin local-branch

This sets the upstream association for any future push/pull attempts automatically.
For more details, checkout this detailed explanation about upstream branches and tracking.

To avoid confusion, recent versions of git deprecate this somewhat ambiguous --set-upstream option in favour of a more verbose --set-upstream-to option with identical syntax and behaviour

git branch --set-upstream-to <origin/remote-branch>

In my case with tomcat projects I have checked project here: Window - Preferences - Tomcat - Source Path - Add java projects to source path

ag (the silver searcher) has pretty simple syntax for this

       -G --file-search-regex PATTERN
          Only search files whose names match PATTERN.

so

ag -G *.h -G *.cpp CP_Image <path>

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

I would also recommend using the Perl debugger.

However, since you asked about something like shell's -x have a look at the Devel::Trace module which does something similar.

Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.

Sub unhidesheet()

Dim ws As Worksheet
Dim pw As String

pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then

   Exit Sub
ElseIf pw = NullString Then
   Exit Sub
ElseIf pw = 123456 Then
    For Each ws In ThisWorkbook.Worksheets
        ws.Visible = xlSheetVisible
    Next
End If
End Sub

You mean you don't know the sizes of the arrays at compile-time? At run-time they could be found by the value of lastone.length and lastwo.length .

For your code to compile you need to cast the result to an int.

int abc = (int) (Math.random() * 100);

However, if you instead use the java.util.Random class it has built in method for you

Random random = new Random();
int abc = random.nextInt(100);

check all the variables names in both of the combined files. Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors. I was facing the same problem as well, and after making all names same in both the file, rbind works accurately.

Thanks

When TypeScript thinks that property "x" does not exist on "y", then you can always cast "y" into "any", which will allow you to call anything (like "x") on "y".

Theory

(<any>y).x;

Real World Example

I was getting the error "TS2339: Property 'name' does not exist on type 'Function'" for this code:

let name: string = this.constructor.name;

So I fixed it with:

let name: string = (<any>this).constructor.name;

Here's a really nice one-liner to print all the Gems along with their version, homepage, and description:

Gem::Specification.sort{|a,b| a.name <=> b.name}.map {|a| puts "#{a.name} (#{a.version})"; puts "-" * 50; puts a.homepage; puts a.description; puts "\n\n"};nil

For me above solutions didn't work then I tried

map.setCenter(new google.maps.LatLng(lat, lng));

and it worked as expected.

Like other have said, span is an in-line element.

See here: http://www.w3.org/TR/CSS2/visuren.html

Additionally, you can make a span behave like a div by applying a

style="display: block; margin: 0px auto; text-align: center;"

In recent updates of JavaFX, you have to set new text in Platform.runLater method just like this:

    private void set_normal_number(TextField textField, String oldValue, String newValue) {
    try {
        int p = textField.getCaretPosition();
        if (!newValue.matches("\\d*")) {
            Platform.runLater(() -> {
                textField.setText(newValue.replaceAll("[^\\d]", ""));
                textField.positionCaret(p);
            });
        }
    } catch (Exception e) {
    }
}

It's a good idea to set caret position too.

string connString = "<your connection string>";
string sql = "name of your sp";

using(SqlConnection conn = new SqlConnection(connString)) 
{
    try 
    {
        using(SqlDataAdapter da = new SqlDataAdapter()) 
        {
            da.SelectCommand = new SqlCommand(sql, conn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;

            DataSet ds = new DataSet();   
            da.Fill(ds, "result_name");

            DataTable dt = ds.Tables["result_name"];

            foreach (DataRow row in dt.Rows) {
                //manipulate your data
            }
        }    
    } 
    catch(SQLException ex) 
    {
        Console.WriteLine("SQL Error: " + ex.Message);
    }
    catch(Exception e) 
    {
        Console.WriteLine("Error: " + e.Message);
    }
}

I got exactely the same error when I have stopped mysql service, and here how to solve it: by (re)starting mysql using these commands:

sudo systemctl start mysql

or

sudo systemctl restart mysql

It looks like your TimeStamp is being set to the timezone of the originating system.

This is deprecated, but it should work:

cal.setTimeInMillis(ts_.getTime() - ts_.getTimezoneOffset());

The non-deprecated way is to use

Calendar.get(Calendar.ZONE_OFFSET) + Calendar.get(Calendar.DST_OFFSET)) / (60 * 1000)

but that would need to be done on the client side, since that system knows what timezone it is in.

Since the suggestion of a loop implies the request for a procedure type solution. Here is mine.

Any query which works on any single record taken from a table can be wrapped in a procedure to make it run through each row of a table like so:

First delete any existing procedure with the same name, and change the delimiter so your SQL doesn't try to run each line as you're trying to write the procedure.

DROP PROCEDURE IF EXISTS ROWPERROW;
DELIMITER ;;

Then here's the procedure as per your example (table_A and table_B used for clarity)

CREATE PROCEDURE ROWPERROW()
BEGIN
DECLARE n INT DEFAULT 0;
DECLARE i INT DEFAULT 0;
SELECT COUNT(*) FROM table_A INTO n;
SET i=0;
WHILE i<n DO 
  INSERT INTO table_B(ID, VAL) SELECT (ID, VAL) FROM table_A LIMIT i,1;
  SET i = i + 1;
END WHILE;
End;
;;

Then dont forget to reset the delimiter

DELIMITER ;

And run the new procedure

CALL ROWPERROW();

You can do whatever you like at the "INSERT INTO" line which I simply copied from your example request.

Note CAREFULLY that the "INSERT INTO" line used here mirrors the line in the question. As per the comments to this answer you need to ensure that your query is syntactically correct for which ever version of SQL you are running.

In the simple case where your ID field is incremented and starts at 1 the line in the example could become:

INSERT INTO table_B(ID, VAL) VALUES(ID, VAL) FROM table_A WHERE ID=i;

Replacing the "SELECT COUNT" line with

SET n=10;

Will let you test your query on the first 10 record in table_A only.

One last thing. This process is also very easy to nest across different tables and was the only way I could carry out a process on one table which dynamically inserted different numbers of records into a new table from each row of a parent table.

If you need it to run faster then sure try to make it set based, if not then this is fine. You could also rewrite the above in cursor form but it may not improve performance. eg:

DROP PROCEDURE IF EXISTS cursor_ROWPERROW;
DELIMITER ;;

CREATE PROCEDURE cursor_ROWPERROW()
BEGIN
  DECLARE cursor_ID INT;
  DECLARE cursor_VAL VARCHAR;
  DECLARE done INT DEFAULT FALSE;
  DECLARE cursor_i CURSOR FOR SELECT ID,VAL FROM table_A;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
  OPEN cursor_i;
  read_loop: LOOP
    FETCH cursor_i INTO cursor_ID, cursor_VAL;
    IF done THEN
      LEAVE read_loop;
    END IF;
    INSERT INTO table_B(ID, VAL) VALUES(cursor_ID, cursor_VAL);
  END LOOP;
  CLOSE cursor_i;
END;
;;

Remember to declare the variables you will use as the same type as those from the queried tables.

My advise is to go with setbased queries when you can, and only use simple loops or cursors if you have to.

Bdizzle,

I would recommend that you read this link

You will see that Newsletters can have different widths, There seems to be no major standard, What is recommended is that the width will be about 95% of the page width, as different browsers use the extra margins differently. You will also find that email readers have problems when reading css so applying the guide lines in this tutorial might help you save some time and trouble-shooting down the road.

Be happy, Julian

Very simple ! Here is my suggestion :

If you want to select dataframes in your workspace, try this :

Filter(function(x) is.data.frame(get(x)) , ls())

or

ls()[sapply(ls(), function(x) is.data.frame(get(x)))]

all these will give the same result.

You can change is.data.frame to check other types of variables like is.function

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html

Maybe it's a coincidence that the column order you want happens to have column names in descending alphabetical order. Since that's the case you could just do:

df<-df[,order(colnames(df),decreasing=TRUE)]

That's what I use when I have large files with many columns.

<input ... checked />
<input ... checked="checked" />

Those are equally valid. And in JavaScript:

input.checked = true;
input.setAttribute("checked");
input.setAttribute("checked","checked");

This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.

First, use ReactiveFormsModule instead of or in addition to the normal FormsModule. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.

The end result will look a little like this, conceptually:

• You have one base FormGroup with whatever FormControl instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.

• Inside that FormGroup instance there will be one or more FormArray instances. A FormArray is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup instances in your array and use those as essentially "mini-forms" nested within your larger form.

• By nesting multiple FormGroup and/or FormControl instances within a dynamic FormArray, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.

• As a FormArray is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.

In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:

Base Component code:

import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'my-form-component',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
    @Input() inputArray: ArrayType[];
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        let newForm = this.fb.group({
            appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
            formArray: this.fb.array([])
        });

        const arrayControl = <FormArray>newForm.controls['formArray'];
        this.inputArray.forEach(item => {
            let newGroup = this.fb.group({
                itemPropertyOne: ['InitialValue', [Validators.required]],
                itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
            });
            arrayControl.push(newGroup);
        });

        this.myForm = newForm;
    }
    addInput(): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        let newGroup = this.fb.group({

            /* Fill this in identically to the one in ngOnInit */

        });
        arrayControl.push(newGroup);
    }
    delInput(index: number): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        arrayControl.removeAt(index);
    }
    onSubmit(): void {
        console.log(this.myForm.value);
        // Your form value is outputted as a JavaScript object.
        // Parse it as JSON or take the values necessary to use as you like
    }
}

Sub-Component Code: (one for each new input field, to keep things clean)

import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';

@Component({
    selector: 'my-form-sub-component',
    templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
    @Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}

Base Component HTML

<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <label>Appears Once:</label>
    <input type="text" formControlName="appearsOnce" />

    <div formArrayName="formArray">
        <div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
            <button type="button" (click)="delInput(i)">Delete</button>
            <my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
        </div>
    </div>
    <button type="button" (click)="addInput()">Add</button>
    <button type="submit" [disabled]="!myForm.valid">Save</button>

Sub-Component HTML

<div [formGroup]="form">
    <label>Property One: </label>
    <input type="text" formControlName="propertyOne"/>

    <label >Property Two: </label>
    <input type="number" formControlName="propertyTwo"/>
</div>

In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup instance within the FormArray situated inside the base FormGroup. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.

Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.

If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.

Go to Settings->Basic, on top you will find a Switch button which will say App is in development mode.

Click on in development switch button, it will ask you to make app live, and after providing all necessary things, it will become live.

I might be a bit late, BUT... I believe it is the best solution. Set it up in your application.yml (or analogical config file):

spring:
    data:
        rest:
            basePath: /api

As I can remember that's it - all of your repositories will be exposed beneath this URI.

You could use the window’s name window.name to store the information. This is known as JavaScript session. But it only works as long as the same window/tab is used.

You could use an immutable struct

public struct Data
{
    public Data(int intValue, string strValue)
    {
        IntegerData = intValue;
        StringData = strValue;
    }

    public int IntegerData { get; private set; }
    public string StringData { get; private set; }
}

var list = new List<Data>();

Or a KeyValuePair<int, string>

using Data = System.Collections.Generic.KeyValuePair<int, string>
...
var list = new List<Data>();
list.Add(new Data(12345, "56789"));

I extended @Ben Lesh's answer with an ability to specify whether the validation is case sensitive or not (default)

use:

<input type="text" name="fruitName" ng-model="data.fruitName" blacklist="Coconuts,Bananas,Pears" caseSensitive="true" required/>

code:

angular.module('crm.directives', []).
directive('blacklist', [
    function () {
        return {
            restrict: 'A',
            require: 'ngModel',
            scope: {
                'blacklist': '=',
            },
            link: function ($scope, $elem, $attrs, modelCtrl) {

                var check = function (value) {
                    if (!$attrs.casesensitive) {
                        value = (value && value.toUpperCase) ? value.toUpperCase() : value;

                        $scope.blacklist = _.map($scope.blacklist, function (item) {
                            return (item.toUpperCase) ? item.toUpperCase() : item
                        })
                    }

                    return !_.isArray($scope.blacklist) || $scope.blacklist.indexOf(value) === -1;
                }

                //For DOM -> model validation
                modelCtrl.$parsers.unshift(function (value) {
                    var valid = check(value);
                    modelCtrl.$setValidity('blacklist', valid);

                    return value;
                });
                //For model -> DOM validation
                modelCtrl.$formatters.unshift(function (value) {
                    modelCtrl.$setValidity('blacklist', check(value));
                    return value;
                });
            }
        };
    }
]);

.outside {
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Needs to be

.outside {
    position: relative;
    width: 200px;
    height: 200px;
    background-color: #EEE; /*to make it visible*/
}

Absolute positioning looks for the nearest relatively positioned parent within the DOM, if one isn't defined it will use the body.

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

1. Right Click on project
2. BuildPath
3. Add External Archives
4. select the .jar file

You can parse according to tag/parent/child very comfortably

For your current structure, you could also try the following:

select cash.Country, cash.Value, cheque.Value, cash.Value + cheque.Value as [Total]
from Cash
join Cheque
on cash.Country = cheque.Country

I think I prefer a union between the two tables, and a group by on the country name as mentioned above.

But I would also recommend normalising your tables. Ideally you'd have a country table, with Id and Name, and a payments table with: CountryId (FK to countries), Total, Type (cash/cheque)

Try this

#movie_item {
    display: block;
    margin-top: 10px;
    height: 175px;
}

.movie_item_poster {
    float: left;
    height: 150px;
    width: 100px;
    background: red;
}

#movie_item_content {
    float: left;
    background: gold;
}

.movie_item_content_title {
    display: block;
}

.movie_item_content_year {
    float: right;
}

.movie_item_content_plot {
    display: block;

}

.movie_item_toolbar {
    clear: both;
    vertical-align: bottom;
    width: 100%;
    height: 25px;
}

In Html

<div id="movie_item">
    <div class="movie_item_poster">
        <img src="..." style="max-width: 100%; max-height: 100%;">
    </div>

     <div id="movie_item_content">
            <div class="movie_item_content_year">(1890-)</div>
        <div class="movie_item_content_title">title my film is a long word</div>
        <div class="movie_item_content_plot">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Officia, ratione, aliquam, earum, quibusdam libero rerum iusto exercitationem reiciendis illo corporis nulla ducimus suscipit nisi dolore explicabo. Accusantium porro reprehenderit ad!</div>
    </div>

    <div class="movie_item_toolbar">
        Lorem Ipsum...
    </div>
</div>

I change position div year.

Escape it. The pipe symbol is one that has been handled differently over time and between browsers. For instance, Chrome and Firefox convert a URL with pipe differently when copy/paste them. However, the most compatible, and necessary with Tomcat 8.5 it seems, is to escape it:

http://localhost:8080/app/handleResponse?msg=name%7Cid%7C

Recently I had to deal with FF which underlines were too thick and too far from the text in FF, and found a better way to deal with it using a pair of box-shadows:

.custom-underline{
    box-shadow: inset 0 0px 0 white, inset 0 -1px 0 black
}

First shadow is put on top of the second one and that's how you can control the second one by varying the 'px' value of both.

Plus: various colors, thickness and underline position

Minus: can not use on non-solid backgrounds

Here I made couple of examples: http://jsfiddle.net/xsL6rktx/

the simplest solution is.....open your website in vs2013 and go to Debug->WebsiteProperties (last option) a new window will open..

in this window go to "Build" option and change .net framework version from 4.5 to 4.0.....then select ok. [note: this step will only work if your project does not have dependencies with vs2013...]

Now open your website in vs2010

You need to make sure the standalone ChromeDriver binary (which is different than the Chrome browser binary) is either in your path or available in the webdriver.chrome.driver environment variable.

see http://code.google.com/p/selenium/wiki/ChromeDriver for full information on how wire things up.

Edit:

Right, seems to be a bug in the Python bindings wrt reading the chromedriver binary from the path or the environment variable. Seems if chromedriver is not in your path you have to pass it in as an argument to the constructor.

import os
from selenium import webdriver

chromedriver = "/Users/adam/Downloads/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)
driver.get("http://stackoverflow.com")
driver.quit()

My problem was unrelated to processData. It was because I sent a function that cannot be called later with apply because it did not have enough arguments. Specifically I shouldn't have used alert as the error callback.

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    processData: false,
    error: alert
});

See this answer for more information on why that can be a problem: Why are certain function calls termed "illegal invocations" in JavaScript?

The way I was able to discover this was by adding a console.log(list[ firingIndex ]) to jQuery so I could track what it was firing.

This was the fix:

function myError(jqx, textStatus, errStr) {
    alert(errStr);
}

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    error: myError // Note that passing `alert` instead can cause a "jquery.js:3189 Uncaught TypeError: Illegal invocation" sometimes
});

You can easily do it after use array_values() and array_filter() function together to remove empty array elements and reindex from an array in PHP.

array_filter() function The PHP array_filter() function remove empty array elements or values from an array in PHP. This will also remove blank, null, false, 0 (zero) values.

array_values() function The PHP array_values() function returns an array containing all the values of an array. The returned array will have numeric keys, starting at 0 and increase by 1.

Remove Empty Array Elements and Reindex

First let’s see the $stack array output :

<?php
  $stack = array("PHP", "HTML", "CSS", "", "JavaScript", null, 0);
  print_r($stack);
?>

Output:

Array
(
    [0] => PHP
    [1] => HTML
    [2] => CSS
    [3] => 
    [4] => JavaScript
    [5] => 
    [6] => 0
)

In above output we want to remove blank, null, 0 (zero) values and then reindex array elements. Now we will use array_values() and array_filter() function together like in below example:

<?php
  $stack = array("PHP", "HTML", "CSS", "", "JavaScript", null, 0);
  print_r(array_values(array_filter($stack)));
?>

Output:

Array
(
    [0] => PHP
    [1] => HTML
    [2] => CSS
    [3] => JavaScript
)

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

  <script >
window.onload = setInterval(clock,1000);
function clock()
{
    var d = new Date();
    var date = d.getDate();
    var year = d.getFullYear();
    var month = d.getMonth();
    var monthArr = ["January", "February","March", "April", "May", "June", "July", "August", "September", "October", "November","December"];
    month = monthArr[month];
    document.getElementById("date").innerHTML=date+" "+month+", "+year;
}

CharField has max_length of 255 characters while TextField can hold more than 255 characters. Use TextField when you have a large string as input. It is good to know that when the max_length parameter is passed into a TextField it passes the length validation to the TextArea widget.

As the others already mentioned: the division operator is / rather than **. If you wanna print the ** character within a string you have to escape it:

print("foo \\")
# will print: foo \

I think to print the string you wanted I think you gonna need this code:

print("Length between sides: " + str((length*length)*2.6) + " \\ 1.5 = " + str(((length*length)*2.6)/1.5) + " Units")

And this one is a more readable version of the above (using the format method):

message = "Length between sides: {0} \\ 1.5 = {1} Units"
val1 = (length * length) * 2.6
val2 = ((length * length) * 2.6) / 1.5
print(message.format(val1, val2))

Try this:

var date = new Date();
console.log(date instanceof Date && !isNaN(date.valueOf()));

This should return true.
