Just use this this decrypter to decrypt your locally cached username & password.

By default, TortoiseSVN stores your cached credentials inside files in the %APPDATA%\Subversion\auth\svn.simple directory. The passwords are encrypted using the Windows Data Protection API, with a key tied to your user account. This tool reads the files and uses the API to decrypt your passwords

Assign fx:id or declare variable to/of any node: anchorpane, button, etc. Then add event handler to it and within that event handler insert the given code below:

Stage stage = (Stage)((Node)((EventObject) eventVariable).getSource()).getScene().getWindow();

Hope, this works for you!!

You can do this:

//first get all the <a> elements
List<WebElement> linkList=driver.findElements(By.tagName("a"));

//now traverse over the list and check
for(int i=0 ; i<linkList.size() ; i++)
{
    if(linkList.get(i).getAttribute("href").contains("long"))
    {
        linkList.get(i).click();
        break;
    }
}

in this what we r doing is first we are finding all the <a> tags and storing them in a list.After that we are iterating the list one by one to find <a> tag whose href attribute contains long string. And then we click on that particular <a> tag and comes out of the loop.

There's a real nice library that does this among other nice pipes. It's called ngx-pipes.

For example, keys pipe returns keys for an object, and values pipe returns values for an object:

keys pipe

<div *ngFor="let key of {foo: 1, bar: 2} | keys">{{key}}</div> 
<!-- Output: 'foo' and 'bar -->

values pipe

<div *ngFor="let value of {foo: 1, bar: 2} | values">{{value}}</div>
<!-- Output: 1 and 2 -->

No need to create your own custom pipe :)

map.at("key") throws exception if missing key

If k does not match the key of any element in the container, the function throws an out_of_range exception.

Generally, EXC_BAD_INSTRUCTION means that there was an assertion failure in your code. A wild guess, your Screen.text is not an integer. Double check its type.

Tried it out. ResponseHeaders do not include status code.

If I'm not mistaken, WebClient is capable of abstracting away multiple distinct requests in a single method call (e.g. correctly handling 100 Continue responses, redirects, and the like). I suspect that without using HttpWebRequest and HttpWebResponse, a distinct status code may not be available.

It occurs to me that, if you are not interested in intermediate status codes, you can safely assume the final status code is in the 2xx (successful) range, otherwise, the call would not be successful.

The status code unfortunately isn't present in the ResponseHeaders dictionary.

You can't, you'll have to do something like

<script type="text/javascript">
   var php_var = "<?php echo $php_var; ?>";
</script>

You can also load it with AJAX

rhino is right, the snippet lacks of a type for the sake of brevity.

Also, note that if $php_var has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

Remove the file: C:/Sites/folder/Pids/Server.pids

Explanation In UNIX land at least we usually track the process id (pid) in a file like server.pid. I think this is doing the same thing here. That file was probably left over from a crash.

A functional programming is identical to procedural programming in which global variables are not being used.

I will add that if your need is just to override a property used by your bean, the id approach works too like skaffman explained :

In your first called XML configuration file :

   <bean id="myBeanId" class="com.blabla">
       <property name="myList" ref="myList"/>
   </bean>

   <util:list id="myList">
       <value>3</value>
       <value>4</value>
   </util:list>

In your second called XML configuration file :

   <util:list id="myList">
       <value>6</value>
   </util:list>

Then your bean "myBeanId" will be instantiated with a "myList" property of one element which is 6.

I know I am late to the party, but I'll quote like they say, "better be late than never". So let us get going, Everybody has their own ways to explain things, let me try to sum it up and simple it up for you in a few steps with an example; Suppose you have a simple form, form.jsp

<form:form action="processForm" modelAttribute="student">
First Name : <form:input path="firstName" /> 
<br><br>
Last Name : <form:input path="lastName" />
<br><br>
<input type="submit" value="submit"/>
</form:form>

path="firstName" path="lastName" These are the fields/properties in the StudentClass when the form is called their getters are called but once submitted their setters are called and their values are set in the bean that was indicated in the modelAttribute="student" in the form tag.

We have StudentController that includes the following methods;

@RequestMapping("/showForm")
public String showForm(Model theModel){ //Model is used to pass data between 
//controllers and views
    theModel.addAttribute("student", new Student()); //attribute name, value
return "form";
}

@RequestMapping("/processForm")
public String processForm(@ModelAttribute("student") Student theStudent){
    System.out.println("theStudent :"+ theStudent.getLastName());
return "form-details";
}

//@ModelAttribute("student") Student theStudent
//Spring automatically populates the object data with form data all behind the 
//scenes 

now finally we have a form-details.jsp

<b>Student Information</b>
${student.firstName}
${student.lastName}

So back to the question What is @ModelAttribute in Spring MVC? A sample definition from the source for you, http://www.baeldung.com/spring-mvc-and-the-modelattribute-annotation The @ModelAttribute is an annotation that binds a method parameter or method return value to a named model attribute and then exposes it to a web view.

What actually happens is it gets all the values of your form those were submitted by it and then holds them for you to bind or assign them to the object. It works same like the @RequestParameter where we only get a parameter and assign the value to some field. Only difference is @ModelAttribute holds all form data rather than a single parameter. It creates a bean for you that holds form submitted data to be used by the developer later on.

To recap the whole thing. Step 1 : A request is sent and our method showForm runs and a model, a temporary bean is set with the name student is forwarded to the form. theModel.addAttribute("student", new Student());

Step 2 : modelAttribute="student" on form submission model changes the student and now it holds all parameters of the form

Step 3 : @ModelAttribute("student") Student theStudent We fetch the values being hold by @ModelAttribute and assign the whole bean/object to Student.

Step 4 : And then we use it as we bid, just like showing it on the page etc like I did

I hope it helps you to understand the concept. Thanks

The best approach in this case is to use extension_loaded() or function_exists() they are equally as fast.

You can see evidence here:

https://github.com/dragoonis/ppi-framework/blob/master/Cache/Memcached.php#L140

Bear in mind that some PHP extensions such as APC have php.ini settings that can disable them even though the extension may be loaded. Here is an example of how to check against that also:

https://github.com/dragoonis/ppi-framework/blob/master/Cache/Apc.php#L79

Hope this helps.

You say you're using:

time.asctime(time.localtime(date_in_seconds_from_bash))

where date_in_seconds_from_bash is presumably the output of date +%s.

The time.localtime function, as the name implies, gives you local time.

If you want UTC, use time.gmtime() rather than time.localtime().

As JamesNoonan33's answer says, the output of date +%s is timezone invariant, so date +%s is exactly equivalent to date -u %s. It prints the number of seconds since the "epoch", which is 1970-01-01 00:00:00 UTC. The output you show in your question is entirely consistent with that:

date -u
Thu Jul 3 07:28:20 UTC 2014

date +%s
1404372514   # 14 seconds after "date -u" command

date -u +%s
1404372515   # 15 seconds after "date -u" command

I have not seen ANY advantages in MVC over ASP.Net. 10 years ago Microsoft came up with UIP (User Interface Process) as the answer to MVC. It was a flop. We did a large project (4 developers, 2 designers, 1 tester) with UIP back then and it was a sheer nightmare.

Don't just jump in to bandwagon for the sake of Hype. All of the advantages listed above are already available in Asp.Net (With more great tweaks [ New features in Asp.Net 4 ] in Asp.Net 4).

If your development team or a single developer families with Asp.Net just stick to it and make beautiful products quickly to satisfy your clients (who pays for your work hours). MVC will eat up your valuable time and produce the same results as Asp.Net :-)

I think you meant something like this: JSON Visualization

Don't know if you might use it, but you might ask the author.

In my case, there is a single table which happens to be a device list from a router. If you wish to read the table using TR/TH/TD (row, header, data) instead of a matrix as mentioned above, you can do something like the following:

    List<TableRow> deviceTable = (from table in document.DocumentNode.SelectNodes(XPathQueries.SELECT_TABLE)
                                       from row in table?.SelectNodes(HtmlBody.TR)
                                       let rows = row.SelectSingleNode(HtmlBody.TR)
                                       where row.FirstChild.OriginalName != null && row.FirstChild.OriginalName.Equals(HtmlBody.T_HEADER)
                                       select new TableRow
                                       {
                                           Header = row.SelectSingleNode(HtmlBody.T_HEADER)?.InnerText,
                                           Data = row.SelectSingleNode(HtmlBody.T_DATA)?.InnerText}).ToList();
                                       }  

TableRow is just a simple object with Header and Data as properties. The approach takes care of null-ness and this case:

<tr>_x000D_
    <td width="28%">&nbsp;</td>_x000D_
</tr>

which is row without a header. The HtmlBody object with the constants hanging off of it are probably readily deduced but I apologize for it even still. I came from the world where if you have " in your code, it should either be constant or localizable.

$no_of_digit = 10;
$number = 123;

$length = strlen((string)$number);
for($i = $length;$i<$no_of_digit;$i++)
{
    $number = '0'.$number;
}

echo $number; ///////  result 0000000123

Think I figured out a way to look inside the GAC without modifying the registry or using the command line, powershell, or any other programs:

Create a new shortcut (to anywhere). Then modify the shortcut to have the target be:

%windir%\assembly\GAC_MSIL\System

Opening this shortcut takes you to the System folder inside the GAC (which everyone should have) and has the wonderful side effect of letting you switch to a higher directory and then browsing into any other folder you want (and see the dll files, etc)

I tested this on windows 7 and windows server 2012.

Note: It will not let you use that target when creating the shortcut but it will let you edit it.

Enjoy!

Here's how to do this in Xamarin.ios.

public class NotificationUtils
{
    public static bool AreNotificationsEnabled ()
    {
        var settings = UIApplication.SharedApplication.CurrentUserNotificationSettings;
        var types = settings.Types;
        return types != UIUserNotificationType.None;
    }
}

If you are supporting iOS 10+ only go with the UNUserNotificationCenter method.

I tried dturvene and all the other solutions, but they didn't work. I needed one more step.

Run these commands

1. adb kill-server
2. android update sdk --no-ui
3. adb start-server

To verify that it worked, run 'adb version' before and after the commands and make sure it is the latest. The reason for the adb kill-server command is that it it most likely running, and it can't be updated while it is running, so you have to kill it first.

Alternative solution to the updated question using Java 8:

Bar[] result = foos.stream()
    .map(x -> new Bar(x))
    .toArray(size -> new Bar[size]);

Several ways to achieve this. Examples are as below

a. return "22".toInteger()
b. if("22".isInteger()) return "22".toInteger()
c. return "22" as Integer()
d. return Integer.parseInt("22")

Hope this helps

If you have Git bash installed, you can do something like this:

/c/Program\ Files\ \(x86\)/PostgreSQL/9.3/bin/psql -U <pg_role_name> -d <pg_database_name> < <path_to_your>.sql

From the HTML point of view everything's been said, but to correct the PHP-side approach a little and taking thirtydot's and icktoofay's advice into account:

<?php echo '<input type="text" name="idtest" value="' . htmlspecialchars($idtest) . '">'; ?>

Elaborating on @Jonathan Ray I think this does the trick a bit better

import time
import inspect

def timed(f:callable):
    start = time.time()
    ret = f()
    elapsed = 1000*(time.time() - start)
    source_code=inspect.getsource(f).strip('\n') 
    logger.info(source_code+":  "+str(elapsed)+" seconds")
    return ret

It allows to take a regular line of code, say a = np.sin(np.pi) and transform it rather simply into

a = timed(lambda: np.sin(np.pi))

so that the timing is printed onto the logger and you can keep the same assignment of the result to a variable you might need for further work.

I suppose in Python 3.8 one could use the := but I do not have 3.8 yet

Node manages dependencies ie; third party code using package.json so that 3rd party modules names and versions can be kept stable for all installs of the project. This also helps keep the file be light-weight as only actual program code is present in the code repository. Whenever repository is cloned, for it to work(as 3rd party modules may be used in the code), you would need to install all dependencies. Use npm install on CMD within root of the project structure to complete installing all dependencies. This should resolve all dependencies issues if dependencies get properly installed.

It's working in 2021,

The user who gets the repo access has to navigate to the repo and can make changes to the main branch.

The body of the loop is indented: indentation is Python’s way of grouping statements. At the interactive prompt, you have to type a tab or space(s) for each indented line. In practice you will prepare more complicated input for Python with a text editor; all decent text editors have an auto-indent facility. When a compound statement is entered interactively, it must be followed by a blank line to indicate completion (since the parser cannot guess when you have typed the last line). Note that each line within a basic block must be indented by the same amount.

This can be an issue when using Source Control and automated deployments to a shared development environment. Where I work we have a very large sample DB on our development tier to work with (a subset of our production data).

Recently I did some work to remove one column from a table and then add some extra ones on the end. I then had to undo my column removal so I re-added it on the end which means the table and all references are correct in the environment but the Source Control automated deployment will no longer work because it complains about the table definition changing.

The real problem here is that the table + indexes are ~120GB and the environment only has ~60GB free so I'll need to either:

a) Rename the existing columns which are in the wrong order, add new columns in the right order, update the data then drop the old columns

OR

b) Rename the table, create a new table with the correct order, insert to the new table from the old and delete from the old as I go along

The SSMS/TFS Schema compare option of using a temp table won't work because there isn't enough room on disc to do it.

I'm not trying to say this is the best way to go about things or that column order really matters, just that I have a scenario where it is an issue and I'm sharing the options I've thought of to fix the issue

If you need to write semantically correct mark-up, even in HTML5, you must not use ' to escape single quotes. Although, I can imagine you actually meant apostrophe rather then single quote.

single quotes and apostrophes are not the same, semantically, although they might look the same.

Here's one apostrophe.

Use ' to insert it if you need HTML4 support. (edited)

In British English, single quotes are used like this:

"He told me to 'give it a try'", I said.

Quotes come in pairs. You can use:

<p><q>He told me to <q>give it a try</q></q>, I said.<p>

to have nested quotes in a semantically correct way, deferring the substitution of the actual characters to the rendering engine. This substitution can then be affected by CSS rules, like:

q {
  quotes: '"' '"' '<' '>';
} 

An old but seemingly still relevant article about semantically correct mark-up: The Trouble With EM ’n EN (and Other Shady Characters).

(edited) This used to be:

Use ’ to insert it if you need HTML4 support.

But, as @James_pic pointed out, that is not the straight single quote, but the "Single curved quote, right".

Try

linq many ways to implement single simple query on collections, just we write joins in sql, a filter can be applied first or last depending on the need and necessity.

Here is an example where we can find an element with a id in a collection. To add more on this, methods First, FirstOrDefault, would ideally return same when a collection has at least one record. If, however, a collection is okay to be empty. then First will return an exception but FirstOrDefault will return null or default. For instance, int will return 0. Thus usage of such is although said to be personal preference, but its better to use FirstOrDefault to avoid exception handling.

If you don't want a timeout happening for some purpose:

<session-config>
    <session-timeout>0</session-timeout>
</session-config>

Should result in no timeout at all -> infinite

i am using centos and getting same error when run mvn command with goal, install. After some googling i have found the solution to run following command.

The error is in your string formatting.

The correct way to use traditional string formatting using the '%' operator is to use a printf-style format string (Python documentation for this here: http://docs.python.org/2/library/string.html#format-string-syntax):

"'%s' is longer than '%s'" % (name1, name2)

However, the '%' operator will probably be deprecated in the future. The new PEP 3101 way of doing things is like this:

"'{0}' is longer than '{1}'".format(name1, name2)

Might as well throw up an actual response with my solution, which was inspired by Peter Liljenberg's:

$ mpstat | awk '$12 ~ /[0-9.]+/ { print 100 - $12"%" }'
0.75%

This will use awk to print out 100 minus the 12th field (idle), with a percentage sign after it. awk will only do this for a line where the 12th field has numbers and dots only ($12 ~ /[0-9]+/).

You can also average five samples, one second apart:

$ mpstat 1 5 | awk 'END{print 100-$NF"%"}'

Test it like this:

$ mpstat 1 5 | tee /dev/tty | awk 'END{print 100-$NF"%"}'

In case anyone wants it, you can also make the timer async and await it:

export const delay = (ms) => new Promise((res) => setTimeout(res, ms));

Usage:

// do something
await delay(500); // wait 0.5 seconds
// do something else

Unique key allows max 2 NULL values. Explaination:

create table teppp
(
id int identity(1,1) primary key,
name varchar(10 )unique,
addresss varchar(10)
)

insert into teppp ( name,addresss) values ('','address1')
insert into teppp ( name,addresss) values ('NULL','address2')
insert into teppp ( addresss) values ('address3')

select * from teppp
null string , address1
NULL,address2
NULL,address3

If you try inserting same values as below:

insert into teppp ( name,addresss) values ('','address4')
insert into teppp ( name,addresss) values ('NULL','address5')
insert into teppp ( addresss) values ('address6')

Every time you will get error like:

Violation of UNIQUE KEY constraint 'UQ__teppp__72E12F1B2E1BDC42'. Cannot insert duplicate key in object 'dbo.teppp'.
The statement has been terminated.

Here's a solution I came up with to generate aesthetically pleasing pastel colours based on an input string. It uses the first two chars of the string as a random seed, then generates R/G/B based on that seed.

It could be easily extended so that the seed is the XOR of all chars in the string, rather than just the first two.

Inspired by David Crow's answer here: Algorithm to randomly generate an aesthetically-pleasing color palette

//magic to convert strings to a nice pastel colour based on first two chars
//
// every string with the same first two chars will generate the same pastel colour
function pastel_colour(input_str) {

    //TODO: adjust base colour values below based on theme
    var baseRed = 128;
    var baseGreen = 128;
    var baseBlue = 128;

    //lazy seeded random hack to get values from 0 - 256
    //for seed just take bitwise XOR of first two chars
    var seed = input_str.charCodeAt(0) ^ input_str.charCodeAt(1);
    var rand_1 = Math.abs((Math.sin(seed++) * 10000)) % 256;
    var rand_2 = Math.abs((Math.sin(seed++) * 10000)) % 256;
    var rand_3 = Math.abs((Math.sin(seed++) * 10000)) % 256;

    //build colour
    var red = Math.round((rand_1 + baseRed) / 2);
    var green = Math.round((rand_2 + baseGreen) / 2);
    var blue = Math.round((rand_3 + baseBlue) / 2);

    return { red: red, green: green, blue: blue };
}

When using the for loop, the value of s is a Map.Entry element, meaning that you can get the key from s.key and the value from s.value

If you have already staged files, simply unstage them:

git reset HEAD [file-name-A.ext] [file-name-B.ext]

Then add them bit by bit back in.

I have a simple solution for this problem. You can first type ":retab" and then ":retab!", then everything would be fine

Maybe EXISTS can help.

and exists (select 1 from @DocumentNames where pcd.Name like DocName+'%' or CD.DocumentName like DocName+'%')

Javascript's String.split unfortunately has no way of limiting the actual number of splits. It has a second argument that specifies how many of the actual split items are returned, which isn't useful in your case. The solution would be to split the string, shift the first item off, then rejoin the remaining items::

var element = $(this).attr('class');
var parts = element.split('_');

parts.shift(); // removes the first item from the array
var field = parts.join('_');

• Your formatting pattern fails to match the input string, as noted by other Answers.
• Your input format is terrible.
• You are using troublesome old date-time classes that were supplanted years ago by the java.time classes.

ISO 8601

Instead a format such as yours, use ISO 8601 standard formats for exchanging date-time values as text.

The java.time classes use the standard ISO 8601 formats by default when parsing/generating strings.

Proper time zone name

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

Your IST could mean Iceland Standard Time, India Standard Time, Ireland Standard Time, or others. The java.time classes are left to merely guessing, as there is no logical solution to this ambiguity.

java.time

The modern approach uses the java.time classes.

Define a formatting pattern to match your input strings.

String input = "Sat Jun 01 12:53:10 IST 2013";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );

zdt.toString(): 2013-06-01T12:53:10Z[Atlantic/Reykjavik]

If your input was not intended for Iceland, you should pre-parse the string to adjust to a proper time zone name. For example, if you are certain the input was intended for India, change IST to Asia/Kolkata.

String input = "Sat Jun 01 12:53:10 IST 2013".replace( "IST" , "Asia/Kolkata" );
DateTimeFormatter f = DateTimeFormatter.ofPattern( "EEE MMM dd HH:mm:ss z uuuu" , Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );

zdt.toString(): 2013-06-01T12:53:10+05:30[Asia/Kolkata]

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Might be a little too late to the party, but hope this helps someone with similar issue.

The reason why your default value doesnt't work is because the migration file sets up the default value in your database (MySQL or PostgreSQL or whatever), and not in your Laravel application.

Let me illustrate with an example.

This line means Laravel is generating a new Book instance, as specified in your model. The new Book object will have properties according to the table associated with the model. Up until this point, nothing is written on the database.

$book = new Book();

Now the following lines are setting up the values of each property of the Book object. Same still, nothing is written on the database yet.

$book->author = 'Test'
$book->title = 'Test'

This line is the one writing to the database. After passing on the object to the database, then the empty fields will be filled by the database (may be default value, may be null, or whatever you specify on your migration file).

$book->save();

And thus, the default value will not pop up before you save it to the database.

But, that is not enough. If you try to access $book->price, it will still be null (or 0, i'm not sure). Saving it is only adding the defaults to the record in the database, and it won't affect the Object you are carrying around.

So, to get the instance with filled-in default values, you have to re-fetch the instance. You may use the

Book::find($book->id);

Or, a more sophisticated way by refreshing the instance

$book->refresh();

And then, the next time you try to access the object, it will be filled with the default values.

Like this:

#include <string>
#include <vector>

struct user
{
    std::string username;
    std::vector<unsigned char> userpassword;
};

int main()
{
    user r;   // r.username is "" and r.userpassword is empty
    // ...
}

$cRepo = $em->getRepository('KaleLocationBundle:Country');

// Leave the first array blank
$countries = $cRepo->findBy(array(), array('name'=>'asc'));

 xslToJson = workbook => {
        //var data = [];
        var sheet_name_list = workbook.SheetNames[0];
        return XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list], {
            raw: false,
            dateNF: "DD-MMM-YYYY",
            header:1,
            defval: ""
        });
    };

    handleFile = (file /*:File*/) => {
        /* Boilerplate to set up FileReader */
        const reader = new FileReader();
        const rABS = !!reader.readAsBinaryString;

        reader.onload = e => {
            /* Parse data */
            const bstr = e.target.result;
            const wb = XLSX.read(bstr, { type: rABS ? "binary" : "array" });
            /* Get first worksheet */
            let arr = this.xslToJson(wb);

            console.log("arr ", arr)
            var dataNueva = []

            arr.forEach(data => {
                console.log("data renaes ", data)
            })
            // this.setState({ DataEESSsend: dataNueva })
            console.log("dataNueva ", dataNueva)

        };


        if (rABS) reader.readAsBinaryString(file);
        else reader.readAsArrayBuffer(file);
    };

    handleChange = e => {
        const files = e.target.files;
        if (files && files[0]) {
            this.handleFile(files[0]);
        }

$ ssh-add -l 

will also work on Mac OS X v10.8 (Mountain Lion) - v10.10 (Yosemite).

It also supports the option -E to specify the fingerprint format so in case MD5 is needed (it's often used, e.g. by GitHub), just add -E md5 to the command.

You could use array_map():

function add_quotes($str) {
    return sprintf("'%s'", $str);
}

$csv =  implode(',', array_map('add_quotes', $array));

DEMO

Also note that there is fputcsv if you want to write to a file.

Did you mean the executable fails to run , if invoked from any other directory? This is rather a bug on the executable. One potential reason could be the executable requires some shared libraires from the installed folder. You may check environment variable LD_LIBRARY_PATH

I faced the problem with display:none

I have several horizontal bars with transition effects but I wanted to show only part of that container and fold the rest while maintaining the effects. I reproduced a small demo here

The obvious was to wrap those hidden animated bars in a div then toggle that element's height and opacity

.hide{
  opacity: 0;
  height: 0;
}
.bars-wrapper.expanded > .hide{
 opacity: 1;
 height: auto;
}

The animation works well but the issue was that these hidden bars were still consuming space on my page and overlapping other elements

so adding display:none to the hidden wrapper .hide solves the margin issue but not the transition, neither applying display:none or height:0;opacity:0 works on the children elements.

So my final workaround was to give those hidden bars a negative and absolute position and it worked well with CSS transitions.

Jsfiddle

The accepted answer didn't work for me on JQuery 2.x .is(":hover") returns false on every call.

I ended up with a pretty simple solution that works:

function isHovered(selector) {

    return $(selector+":hover").length > 0

}

Expanding a bit on the answers from @Guru and @Ronnis, you can hide the sequence and make it look more like an auto-increment using a trigger, and have a procedure that does the insert for you and returns the generated ID as an out parameter.

create table batch(batchid number,
    batchname varchar2(30),
    batchtype char(1),
    source char(1),
    intarea number)
/

create sequence batch_seq start with 1
/

create trigger batch_bi
before insert on batch
for each row
begin
    select batch_seq.nextval into :new.batchid from dual;
end;
/

create procedure insert_batch(v_batchname batch.batchname%TYPE,
    v_batchtype batch.batchtype%TYPE,
    v_source batch.source%TYPE,
    v_intarea batch.intarea%TYPE,
    v_batchid out batch.batchid%TYPE)
as
begin
    insert into batch(batchname, batchtype, source, intarea)
    values(v_batchname, v_batchtype, v_source, v_intarea)
    returning batchid into v_batchid;
end;
/

You can then call the procedure instead of doing a plain insert, e.g. from an anoymous block:

declare
    l_batchid batch.batchid%TYPE;
begin
    insert_batch(v_batchname => 'Batch 1',
        v_batchtype => 'A',
        v_source => 'Z',
        v_intarea => 1,
        v_batchid => l_batchid);
    dbms_output.put_line('Generated id: ' || l_batchid);

    insert_batch(v_batchname => 'Batch 99',
        v_batchtype => 'B',
        v_source => 'Y',
        v_intarea => 9,
        v_batchid => l_batchid);
    dbms_output.put_line('Generated id: ' || l_batchid);
end;
/

Generated id: 1
Generated id: 2

You can make the call without an explicit anonymous block, e.g. from SQL*Plus:

variable l_batchid number;
exec insert_batch('Batch 21', 'C', 'X', 7, :l_batchid);

... and use the bind variable :l_batchid to refer to the generated value afterwards:

print l_batchid;
insert into some_table values(:l_batch_id, ...);

Compare document.activeElement with the element you want to check for focus. If they are the same, the element is focused; otherwise, it isn't.

// dummy element
var dummyEl = document.getElementById('myID');

// check for focus
var isFocused = (document.activeElement === dummyEl);

hasFocus is part of the document; there's no such method for DOM elements.

Also, document.getElementById doesn't use a # at the beginning of myID. Change this:

var dummyEl = document.getElementById('#myID');

to this:

var dummyEl = document.getElementById('myID');

If you'd like to use a CSS query instead you can use querySelector (and querySelectorAll).

The correct syntax is the following:

<div [innerHTML]="theHtmlString"></div>

Documentation Reference

the getText method returns a String, while the setText receives a String, so you can write it like label1.setText(nameField.getText()); in your listener.

GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.

A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.

http://developer.android.com/guide/topics/location/obtaining-user-location.html

To change the EditText background dynamically, you can use ColorStateList.

int[][] states = new int[][] {
    new int[] { android.R.attr.state_enabled}, // enabled
    new int[] {-android.R.attr.state_enabled}, // disabled
    new int[] {-android.R.attr.state_checked}, // unchecked
    new int[] { android.R.attr.state_pressed}  // pressed
};

int[] colors = new int[] {
    Color.BLACK,
    Color.RED,
    Color.GREEN,
    Color.BLUE
};

ColorStateList colorStateList = new ColorStateList(states, colors);

Credits: This SO answer about ColorStateList is awesome.

The term cohesion is indeed a little counter intuitive for what it means in software design.

Cohesion common meaning is that something that sticks together well, is united, which are characterized by strong bond like molecular attraction. However in software design, it means striving for a class that ideally does only one thing, so multiple sub-modules are not even involved.

Perhaps we can think of it this way. A part has the most cohesion when it is the only part (does only one thing and can't be broken down further). This is what is desired in software design. Cohesion simply is another name for "single responsibility" or "separation of concerns".

The term coupling on the hand is quite intuitive which means when a module doesn't depend on too many other modules and those that it connects with can be easily replaced for example obeying liskov substitution principle .

Use AssemblyInfo.cs

Create the file in App_Code: and fill out the following or use Google for other attribute/property possibilities.

AssemblyInfo.cs

using System.Reflection;

[assembly: AssemblyDescription("Very useful stuff here.")]
[assembly: AssemblyCompany("companyname")]
[assembly: AssemblyCopyright("Copyright © me 2009")]
[assembly: AssemblyProduct("NeatProduct")]
[assembly: AssemblyVersion("1.1.*")]

AssemblyVersion being the part you are really after.

Then if you are working on a website, in any aspx page, or control, you can add in the <Page> tag, the following:

CompilerOptions="<folderpath>\App_Code\AssemblyInfo.cs"

(replacing folderpath with appropriate variable of course).

I don't believe you need to add compiler options in any manner for other classes; all the ones in the App_Code should receive the version information when they are compiled.

Hope that helps.

Putting it another way:

A complete graph is an undirected graph where each distinct pair of vertices has an unique edge connecting them. This is intuitive in the sense that, you are basically choosing 2 vertices from a collection of n vertices.

nC2 = n!/(n-2)!*2! = n(n-1)/2

This is the maximum number of edges an undirected graph can have. Now, for directed graph, each edge converts into two directed edges. So just multiply the previous result with two. That gives you the result: n(n-1)

Here's another form of a solution with normalization of your time object:

def to_unix_time(timestamp):
    epoch = datetime.datetime.utcfromtimestamp(0) # start of epoch time
    my_time = datetime.datetime.strptime(timestamp, "%Y/%m/%d %H:%M:%S.%f") # plugin your time object
    delta = my_time - epoch
    return delta.total_seconds() * 1000.0

Have a look at config.sample.inc.php: you will find examples of the configuration directives that you should copy to your config.inc.php (copy the missing ones). Then, have a look at examples/create_tables.sql which will help you create the missing tables.

The complete documentation for this is available at http://docs.phpmyadmin.net/en/latest/setup.html#phpmyadmin-configuration-storage.

You can use

    ${var == null}

alternatively.

>>>>     n_ = np.sum(arr >= thresh)
>>>>     return sorted_args[:n_]
>>>> get_top_n_plus_ties(np.array([2,9,8,3,0,2,8,3,1,9,5]),3)
array([1, 9, 2, 6])

Here is a method adapted from Jquery 2.1.1 that take a dom element instead of a jquery object (so jquery is not needed). Includes type checks and regex expressions:

function addClass(element, value) {
    // Regex terms
    var rclass = /[\t\r\n\f]/g,
        rnotwhite = (/\S+/g);

    var classes,
        cur,
        curClass,
        finalValue,
        proceed = typeof value === "string" && value;

    if (!proceed) return element;

    classes = (value || "").match(rnotwhite) || [];

    cur = element.nodeType === 1
        && (element.className
                ? (" " + element.className + " ").replace(rclass, " ")
                : " "
        );

    if (!cur) return element;

    var j = 0;

    while ((curClass = classes[j++])) {

        if (cur.indexOf(" " + curClass + " ") < 0) {

            cur += curClass + " ";

        }

    }

    // only assign if different to avoid unneeded rendering.
    finalValue = cur.trim();

    if (element.className !== finalValue) {

        element.className = finalValue;

    }

    return element;
};

You can use .addAll() to add the elements of the second list to the first:

array1.addAll(array2);

Edit: Based on your clarification above ("i want a single String in the new Arraylist which has both name and number."), you would want to loop through the first list and append the item from the second list to it.

Something like this:

int length = array1.size();
if (length != array2.size()) { // Too many names, or too many numbers
    // Fail
}
ArrayList<String> array3 = new ArrayList<String>(length); // Make a new list
for (int i = 0; i < length; i++) { // Loop through every name/phone number combo
    array3.add(array1.get(i) + " " + array2.get(i)); // Concat the two, and add it
}

If you put in:

array1 : ["a", "b", "c"]
array2 : ["1", "2", "3"]

You will get:

array3 : ["a 1", "b 2", "c 3"]

An unwanted single quote was my problem. Checking the connection string from the location of the index mentioned in the error string helped me spot the issue.

If you want to map objects to something (in this case a property). I think Array.prototype.map is what you're looking for if you want to code functionally.

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(function(elem){
    return elem.name;
}).join(",");

In modern JavaScript:

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(e => e.name).join(",");

(fiddle)

If you want to support older browsers, that are not ES5 compliant you can shim it (there is a polyfill on the MDN page above). Another alternative would be to use underscorejs's pluck method:

var users = [
      {name: "Joe", age: 22},
      {name: "Kevin", age: 24},
      {name: "Peter", age: 21}
    ];
var result = _.pluck(users,'name').join(",")

Here is the official documentation of ArrayList.get().

Anyway it is very simple, for example

ArrayList list = new ArrayList();
list.add("1");
list.add("2");
list.add("3");
String str = (String) list.get(0); // here you get "1" in str

Thanks for your feed back got it to work I used the sshpass tool.

sshpass -p 'password' scp [email protected]:sys_config /var/www/dev/

Use ftplib, you can write it like this:

import ftplib
session = ftplib.FTP('server.address.com','USERNAME','PASSWORD')
file = open('kitten.jpg','rb')                  # file to send
session.storbinary('STOR kitten.jpg', file)     # send the file
file.close()                                    # close file and FTP
session.quit()

Use ftplib.FTP_TLS instead if you FTP host requires TLS.

To retrieve it, you can use urllib.retrieve:

import urllib 

urllib.urlretrieve('ftp://server/path/to/file', 'file')

EDIT:

To find out the current directory, use FTP.pwd():

FTP.pwd(): Return the pathname of the current directory on the server.

To change the directory, use FTP.cwd(pathname):

FTP.cwd(pathname): Set the current directory on the server.

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Another solution is described also here in case some of the other scripts does not work in your case.

If you are using android studio then give it a try:

I tried this and it worked for me.

This is a definitive un-answer: eliminating a tempting-but-wrong answer to help others navigate toward correct answers.

It might seem like debugging would highlight the problem. However, the only browser the problem occurs in is IE, and in IE you can only debug code that was part of the original document. For dynamically added code, the debugger just shows the body element as the current instruction, and IE claims the error happened on a huge line number.

Here's a sample web page that will demonstrate this problem in IE:

<html>
<head>
<title>javascript debug test</title>
</head>
<body onload="attachScript();">
<script type="text/javascript">
function attachScript() {
   var s = document.createElement("script");
   s.setAttribute("type", "text/javascript");
   document.body.appendChild(s);
   s.text = "var a = document.getElementById('nonexistent'); alert(a.tagName);"
}
</script>
</body>

This yielded for me the following error:

Line: 54654408
Error: Object required

I saw it's solved, but I still want to share a solution which worked for me.

A Table can have a Composite Primary Key which is a primary key made from two or more columns. For example:

CREATE TABLE userdata (
  userid INT,
  userdataid INT,
  info char(200),
  primary key (userid, userdataid)
);

Update: Here is a link with a more detailed description of composite primary keys.

If you are using Postgres.app on Mac, you may resolve this issue once and for all like this:

First gem uninstall pg, then edit your ~/.bash_profile or ~/.zshrc file or equivalent and add:

Then bundle install and gem install pg should both work as expected.

Go to Task->Generate Scripts...

In Advanced in "Types of data for script" select "Schema and data" and try to run this script in your lower version.

You can do this:

SET @dbName = 'TESTDB';

Declare @SQL nvarchar(max);
select @SQL = 'USE ' + @dbName +'; {can put command(s) here}';
EXEC (@SQL);

{but not here!}

This means you can do a recursive select like the following:

Declare @dbName nvarchar(max);
SET @dbName = 'TESTDB';
Declare @SQL nvarchar(max);

SELECT @SQL = 'USE ' + @dbName + '; ' +(Select ... {query here}

Let's say you have the JavaScript file named myscript.js in your root folder. Add the reference to your javascript source file in your head tag of your html file.

On my AWS beanstalk server, I don't see $_SERVER['HTTPS'] variable. I do see $_SERVER['HTTP_X_FORWARDED_PROTO'] which can be either 'http' or 'https' so if you're hosting on AWS, use this:

if ($_SERVER['HTTP_HOST'] != 'localhost' and $_SERVER['HTTP_X_FORWARDED_PROTO'] != "https") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;
}

You can save the struct into a map by matching the struct Key and Value components to their fictive key and value parts on the map:

mapConfig := map[string]string{}
for _, v := range myconfig {
   mapConfig[v.Key] = v.Value
}

Then using the golang comma ok idiom you can test for the key presence:

if v, ok := mapConfig["key1"]; ok {
    fmt.Printf("%s exists", v)
}

The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter:

The directory '/home/someuser/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

The directory '/home/someuser/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Installation without sudo

curl https://bootstrap.pypa.io/get-pip.py | python3.6 - --user

This may sometimes give a warning such as:

WARNING: The script wheel is installed in '/home/ubuntu/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

Verification

After this, pip, pip3, and pip3.6 can all be expected to point to the same target:

$ (pip -V && pip3 -V && pip3.6 -V) | uniq
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Of course you can alternatively use python3.6 -m pip as well.

$ python3.6 -m pip -V
pip 18.0 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Avoid loops. What you want to do is:

import numpy as np
data=np.loadtxt(fname="data.txt")## to load the above two column
print data
print data.sum(axis=1)

I was facing such a problem, look at the picture below

and here is its HTML

<tr class="li1">
    <td valign="top">1.</td>
    <td colspan="5" valign="top">
        <p>How to build e-book learning environment</p>
    </td>
</tr>

so I fix it by changing valign Attribute in both td tags to baseline

and it worked

here is the result

hope this help you

The following worked for me:

$("[id=attached_docs][value=123]")

for Win10 you should remove this folder and close/open your IDE

C:\Users\User\AppData\Roaming\Subversion\auth

, also in my projects no ".subversion" folders, only ".svn"

This is my trigger example:

/************ ROLE ************/_x000D_
drop table if exists `role`;_x000D_
create table `role` (_x000D_
    `id_role` bigint(20) unsigned not null auto_increment,_x000D_
    `date_created` datetime,_x000D_
    `date_deleted` datetime,_x000D_
    `name` varchar(35) not null,_x000D_
    `description` text,_x000D_
    primary key (`id_role`)_x000D_
) comment='';_x000D_
_x000D_
drop trigger if exists `role_date_created`;_x000D_
create trigger `role_date_created` before insert_x000D_
    on `role`_x000D_
    for each row _x000D_
    set new.`date_created` = now();

To answer the question of going from an existing python datetime to a pandas Timestamp do the following:

    import time, calendar, pandas as pd
    from datetime import datetime
    
    def to_posix_ts(d: datetime, utc:bool=True) -> float:
        tt=d.timetuple()
        return (calendar.timegm(tt) if utc else time.mktime(tt)) + round(d.microsecond/1000000, 0)
    
    def pd_timestamp_from_datetime(d: datetime) -> pd.Timestamp:
        return pd.to_datetime(to_posix_ts(d), unit='s')
    
    dt = pd_timestamp_from_datetime(datetime.now())
    print('({}) {}'.format(type(dt), dt))

Output:

(<class 'pandas._libs.tslibs.timestamps.Timestamp'>) 2020-09-05 23:38:55

I was hoping for a more elegant way to do this but the to_posix_ts is already in my standard tool chain so I'm moving on.

You could use a Scanner

http://download.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

The scanner can also use delimiters other than whitespace. This example reads several items in from a string:

     String input = "1 fish 2 fish red fish blue fish";
     Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
     System.out.println(s.nextInt());
     System.out.println(s.nextInt());
     System.out.println(s.next());
     System.out.println(s.next());
     s.close(); 

prints the following output:

     1
     2
     red
     blue

Read Scott Hanselman's post on the issue: http://www.hanselman.com/blog/AReminderOnThreeMultiTierLayerArchitectureDesignBroughtToYouByMyLateNightFrustrations.aspx

Remember though, that in "Scott World" (which is hopefully your world also :) ) a "Tier" is a unit of deployment, while a "Layer" is a logical separation of responsibility within code. You may say you have a "3-tier" system, but be running it on one laptop. You may say your have a "3-layer" system, but have only ASP.NET pages that talk to a database. There's power in precision, friends.

The ISO is probably pre-pidded. You'll need to delete the key from the setup files. It should then ask you for a key during installation.

If you just need to do it one-off, navigate to chrome://extensions. Enable Developer Mode at upper right. The ID will be shown in the box for each extension.

Or, if you're working on developing a userscript or extension, purposefully throw an error. Look in the javascript console, and the ID will be there, on the right side of the console, in the line describing the error.

Lastly, you can look in your chrome extensions directory; it stores extensions in directories named by the ID. This is the worst choice, as you'd have extension IDs, and have to read each manifest.json to figure out which ID was the right one. But if you just installed something, you can also just sort by creation date, and the newest extension directory will be the ID you want.

Xcode 9.2 Swift 4

extension UITextField{
    @IBInspectable var placeHolderColor: UIColor? {
        get {
            return self.placeHolderColor
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedStringKey.foregroundColor: newValue!])
        }
    }
}

Have the same Setup as OP. One controller with many actions... less "messy" :-)

In my case i forgot the "[HttpGet]" when adding a new action.

[HttpGet]
public IEnumerable<string> TestApiCall()
{
    return new string[] { "aa", "bb" };
}

The ADT plug-in is yet not compatible with 3.6

I have been using Eclipse 3.6 with ADT for the past three months for developing applications on Android. I haven't faced any issues so far. It really good and working fine.

You need to change your project settings so that Eclipse-CDT manages your Makefiles for you.

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Under the Builder Settings tab on the right, select "Generate Makefiles automatically" under the Makefile generation section.
4. Hit OK and build again.

Note to anyone else:

If you have a directory like so, you can add a __main__.py file to tell the interpreter what to execute if you call the module directly.

my_module
  |
  | __init__.py
  | my_cool_file.py # print "Hello  World"
  | __main__.py # import my_cool_file

$ python my_module # Hello World

A simple and nice way is:

$time = (Get-Date).ToString("yyyy:MM:dd")

Refer the scripts inside the angular-cli.json (angular.json when using angular 6+) file.

"scripts": [
    "../path" 
 ];

then add in typings.d.ts (create this file in src if it does not already exist)

declare var variableName:any;

Import it in your file as

import * as variable from 'variableName';

find triggers on table:

select so.name, text
from sysobjects so, syscomments sc
where type = 'TR'
and so.id = sc.id
and text like '%TableName%'

and you can find store procedure which has reference of table:

SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%yourtablename%'

.button{
    background-image:url('/image/btn.png');
    background-repeat:no-repeat;
}

.sort(), in pymongo, takes key and direction as parameters.

So if you want to sort by, let's say, id then you should .sort("_id", 1)

For multiple fields:

.sort([("field1", pymongo.ASCENDING), ("field2", pymongo.DESCENDING)])

specifically I want to overload Boolean.Parse to allow an int argument.

Would an extension for int work?

public static bool ToBoolean(this int source){
    // do it
    // return it
}

Then you can call it like this:

int x = 1;

bool y = x.ToBoolean();

with python3, you can use Implementing Multiple Dispatch with Function Annotations as Python Cookbook wrote:

import time


class Date(metaclass=MultipleMeta):
    def __init__(self, year:int, month:int, day:int):
        self.year = year
        self.month = month
        self.day = day

    def __init__(self):
        t = time.localtime()
        self.__init__(t.tm_year, t.tm_mon, t.tm_mday)

and it works like:

>>> d = Date(2012, 12, 21)
>>> d.year
2012
>>> e = Date()
>>> e.year
2018

Since LocalDateSerializer turns it into "[year,month,day]" (a json array) rather than "year-month-day" (a json string) by default, and since I don't want to require any special ObjectMapper setup (you can make LocalDateSerializer generate strings if you disable SerializationFeature.WRITE_DATES_AS_TIMESTAMPS but that requires additional setup to your ObjectMapper), I use the following:

imports:

import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;

code:

// generates "yyyy-MM-dd" output
@JsonSerialize(using = ToStringSerializer.class)
// handles "yyyy-MM-dd" input just fine (note: "yyyy-M-d" format will not work)
@JsonDeserialize(using = LocalDateDeserializer.class)
private LocalDate localDate;

And now I can just use new ObjectMapper() to read and write my objects without any special setup.

My DataGridView is also bound to a DataSource and myDataGridView.Columns.Clear() worked fine but myDataGridView.Rows.Clear() did NOT. Just an FYI for those who have tried .Rows.

You can't access the http headers, but some of the information provided in them is available in the DOM. For example, if you want to see the http referer (sic), use document.referrer. There may be others like this for other http headers. Try googling the specific thing you want, like "http referer javascript".

I know this should be obvious, but I kept searching for stuff like "http headers javascript" when all I really wanted was the referer, and didn't get any useful results. I don't know how I didn't realize I could make a more specific query.

I was in need of a similar kind of solution, wanted to add data on a wall like facebook, when posted,use prepend() to add the latest post on top, thought might be useful for others..

$("#statusupdate").submit( function () {    
          $.post(
           'ajax.php',
            $(this).serialize(),
            function(data){

                $("#box").prepend($(data).fadeIn('slow'));                  
                $("#status").val('');
            }
          );
           event.preventDefault();   
        });   

the code in ajax.php is

if (isset($_POST))
{

    $feed = $_POST['feed'];
    echo "<p id=\"result\" style=\"width:200px;height:50px;background-color:lightgray;display:none;\">$feed</p>";


}

Here is a way to get a NIO FileChannel from System.in and check for availability of data using a timeout, which is a special case of the problem described in the question. Run it at the console, don't type any input, and wait for the results. It was tested successfully under Java 6 on Windows and Linux.

import java.io.FileInputStream;
import java.io.FilterInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.lang.reflect.Field;
import java.nio.ByteBuffer;
import java.nio.channels.ClosedByInterruptException;

public class Main {

    static final ByteBuffer buf = ByteBuffer.allocate(4096);

    public static void main(String[] args) {

        long timeout = 1000 * 5;

        try {
            InputStream in = extract(System.in);
            if (! (in instanceof FileInputStream))
                throw new RuntimeException(
                        "Could not extract a FileInputStream from STDIN.");

            try {
                int ret = maybeAvailable((FileInputStream)in, timeout);
                System.out.println(
                        Integer.toString(ret) + " bytes were read.");

            } finally {
                in.close();
            }

        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }

    /* unravels all layers of FilterInputStream wrappers to get to the
     * core InputStream
     */
    public static InputStream extract(InputStream in)
            throws NoSuchFieldException, IllegalAccessException {

        Field f = FilterInputStream.class.getDeclaredField("in");
        f.setAccessible(true);

        while( in instanceof FilterInputStream )
            in = (InputStream)f.get((FilterInputStream)in);

        return in;
    }

    /* Returns the number of bytes which could be read from the stream,
     * timing out after the specified number of milliseconds.
     * Returns 0 on timeout (because no bytes could be read)
     * and -1 for end of stream.
     */
    public static int maybeAvailable(final FileInputStream in, long timeout)
            throws IOException, InterruptedException {

        final int[] dataReady = {0};
        final IOException[] maybeException = {null};
        final Thread reader = new Thread() {
            public void run() {                
                try {
                    dataReady[0] = in.getChannel().read(buf);
                } catch (ClosedByInterruptException e) {
                    System.err.println("Reader interrupted.");
                } catch (IOException e) {
                    maybeException[0] = e;
                }
            }
        };

        Thread interruptor = new Thread() {
            public void run() {
                reader.interrupt();
            }
        };

        reader.start();
        for(;;) {

            reader.join(timeout);
            if (!reader.isAlive())
                break;

            interruptor.start();
            interruptor.join(1000);
            reader.join(1000);
            if (!reader.isAlive())
                break;

            System.err.println("We're hung");
            System.exit(1);
        }

        if ( maybeException[0] != null )
            throw maybeException[0];

        return dataReady[0];
    }
}

Interestingly, when running the program inside NetBeans 6.5 rather than at the console, the timeout doesn't work at all, and the call to System.exit() is actually necessary to kill the zombie threads. What happens is that the interruptor thread blocks (!) on the call to reader.interrupt(). Another test program (not shown here) additionally tries to close the channel, but that doesn't work either.

In Android O it's a must to use a channel with your Notification Builder

below is a sample code :

// Sets an ID for the notification, so it can be updated.
int notifyID = 1; 
String CHANNEL_ID = "my_channel_01";// The id of the channel. 
CharSequence name = getString(R.string.channel_name);// The user-visible name of the channel.
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
// Create a notification and set the notification channel.
Notification notification = new Notification.Builder(MainActivity.this)
            .setContentTitle("New Message")
            .setContentText("You've received new messages.")
            .setSmallIcon(R.drawable.ic_notify_status)
            .setChannelId(CHANNEL_ID)
            .build();

Or with Handling compatibility by:

NotificationCompat notification =
        new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("My notification")
        .setContentText("Hello World!")
        .setChannelId(CHANNEL_ID).build();

Now make it notify

NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 mNotificationManager.createNotificationChannel(mChannel);

// Issue the notification.
mNotificationManager.notify(notifyID , notification);

or if you want a simple fix then use the following code:

NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
       mNotificationManager.createNotificationChannel(mChannel);
    }

Updates: NotificationCompat.Builder reference

NotificationCompat.Builder(Context context)

This constructor was deprecated in API level 26.0.0 so you should use

Builder(Context context, String channelId)

so no need to setChannelId with the new constructor.

And you should use the latest of AppCompat library currently 26.0.2

compile "com.android.support:appcompat-v7:26.0.+"

Excel 2013 can do Count distinct in pivots. If no access to 2013, and it's a smaller amount of data, I make two copies of the raw data, and in copy b, select both columns and remove duplicates. Then make the pivot and count your column b.

I simplify the code a little bit.

try to change the jre you use.Set the jre in the folder of JDK instead.

You can use jQuery to handle this:

$(function() {
    /**
     * Read the size of the window and reposition the footer at the bottom.
     */
    var stickyFooter = function(){
        var pageHeight = $('html').height();
        var windowHeight = $(window).height();
        var footerHeight = $('footer').outerHeight();

        // A footer with 'fixed-bottom' has the CSS attribute "position: absolute",
        // and thus is outside of its container and counted in $('html').height().
        var totalHeight = $('footer').hasClass('fixed-bottom') ?
            pageHeight + footerHeight : pageHeight;

        // If the window is larger than the content, fix the footer at the bottom.
        if (windowHeight >= totalHeight) {
            return $('footer').addClass('fixed-bottom');
        } else {
            // If the page content is larger than the window, the footer must move.
            return $('footer').removeClass('fixed-bottom');
        }
    };

    // Call when this script is first loaded.
    window.onload = stickyFooter;

    // Call again when the window is resized.
    $(window).resize(function() {
        stickyFooter();
    });
});

SELECT * FROM `DUAL` WHERE id>0 AND id<101

The above query is written in SQL in the database.

Just an update, Feb 1, 2019: cmd+shift+n on Mac now opens a new window where you can drag over tabs. I didn't find that out until I when through KyleMit's response and saw his key mapping suggestion was already mapped to the correct action.

In my case (OS X) it was because I have set GOPATH to /home/username/go (as per the book) instead of /Users/username/go

We should also take in consideration how the compiler threats the generic classes: in "instantiates" a different type whenever we fill the generic arguments.

Thus we have ListOfAnimal, ListOfDog, ListOfCat, etc, which are distinct classes that end up being "created" by the compiler when we specify the generic arguments. And this is a flat hierarchy (actually regarding to List is not a hierarchy at all).

Another argument why covariance doesn't make sense in case of generic classes is the fact that at base all classes are the same - are List instances. Specialising a List by filling the generic argument doesn't extend the class, it just makes it work for that particular generic argument.

Here is an Example to set a Click Listener.

Adapter extends  RecyclerView.Adapter<MessageAdapter.MessageViewHolder> {  ...  }

 public static class MessageViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView     tv_msg;
        public TextView     tv_date;
        public TextView     tv_sendTime;
        public ImageView    sharedFile;
        public ProgressBar sendingProgressBar;

        public MessageViewHolder(View v) {
            super(v);
            tv_msg =  (TextView) v.findViewById(R.id.tv_msg);
            tv_date = (TextView)  v.findViewById(R.id.tv_date);
            tv_sendTime = (TextView)  v.findViewById(R.id.tv_sendTime);
            sendingProgressBar = (ProgressBar) v.findViewById(R.id.sendingProgressBar);
            sharedFile = (ImageView) v.findViewById(R.id.sharedFile);

            sharedFile.setOnClickListener(this);

        }

        @Override
        public void onClick(View view) {
        int position  =   getAdapterPosition();


            switch (view.getId()){
                case R.id.sharedFile:


                    Log.w("", "Selected"+position);


                    break;
            }
        }

    }

In my case nothing above has worked. After banging my head against the wall for a while I've found out, that I've destroyed the /etc/passwd entries by running a custom-made-linux-server-setup-bash-script which worked well previously, but this time the regex within the "sed" command erased all the existing entries :D After copy pasting the default entries from another working linux server I could finally restart sshd.

So don't forget to backup the original /etc/passwd file before applying any regex replacements on it :)

set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);

Using = causes the variable to be assigned a value. If the variable already had a value, it is replaced. This value will be expanded when it is used. For example:

HELLO = world
HELLO_WORLD = $(HELLO) world!

# This echoes "world world!"
echo $(HELLO_WORLD)

HELLO = hello

# This echoes "hello world!"
echo $(HELLO_WORLD)

Using := is similar to using =. However, instead of the value being expanded when it is used, it is expanded during the assignment. For example:

HELLO = world
HELLO_WORLD := $(HELLO) world!

# This echoes "world world!"
echo $(HELLO_WORLD)

HELLO = hello

# Still echoes "world world!"
echo $(HELLO_WORLD)

HELLO_WORLD := $(HELLO) world!

# This echoes "hello world!"
echo $(HELLO_WORLD)

Using ?= assigns the variable a value iff the variable was not previously assigned. If the variable was previously assigned a blank value (VAR=), it is still considered set I think. Otherwise, functions exactly like =.

Using += is like using =, but instead of replacing the value, the value is appended to the current one, with a space in between. If the variable was previously set with :=, it is expanded I think. The resulting value is expanded when it is used I think. For example:

HELLO_WORLD = hello
HELLO_WORLD += world!

# This echoes "hello world!"
echo $(HELLO_WORLD)

If something like HELLO_WORLD = $(HELLO_WORLD) world! were used, recursion would result, which would most likely end the execution of your Makefile. If A := $(A) $(B) were used, the result would not be the exact same as using += because B is expanded with := whereas += would not cause B to be expanded.

        for (int i = 0; i < 1000000; i++)
        {
            DigitsOnlyRegex(phone);
        }
        sw2.Stop();
        Console.WriteLine("Time: " + sw2.ElapsedMilliseconds);

        Console.ReadLine();
    }

    public static string DigitsOnly(string phone, string replace = null)
    {
        if (replace == null) replace = "";
        if (phone == null) return null;
        var result = new StringBuilder(phone.Length);
        foreach (char c in phone)
            if (c >= '0' && c <= '9')
                result.Append(c);
            else

    }

    public static string DigitsOnlyRegex(string phone)
    {
        return digitsOnly.Replace(phone, "");
    }
}

The result in my computer is:

There's also JCommander (disclaimer: I created it):

object Main {
  object Args {
    @Parameter(
      names = Array("-f", "--file"),
      description = "File to load. Can be specified multiple times.")
    var file: java.util.List[String] = null
  }

  def main(args: Array[String]): Unit = {
    new JCommander(Args, args.toArray: _*)
    for (filename <- Args.file) {
      val f = new File(filename)
      printf("file: %s\n", f.getName)
    }
  }
}

Array.indexOf was introduced in JavaScript 1.6, but it is not supported in older browsers. Thankfully the chaps over at Mozilla have done all the hard work for you, and provided you with this for compatibility:

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(elt /*, from*/)
  {
    var len = this.length >>> 0;

    var from = Number(arguments[1]) || 0;
    from = (from < 0)
         ? Math.ceil(from)
         : Math.floor(from);
    if (from < 0)
      from += len;

    for (; from < len; from++)
    {
      if (from in this &&
          this[from] === elt)
        return from;
    }
    return -1;
  };
}

There are even some handy usage snippets for your scripting pleasure.

Distinct and Group By generally do the same kind of thing, for different purposes... They both create a 'working" table in memory based on the columns being Grouped on, (or selected in the Select Distinct clause) - and then populate that working table as the query reads data, adding a new "row" only when the values indicate the need to do so...

The only difference is that in the Group By there are additional "columns" in the working table for any calculated aggregate fields, like Sum(), Count(), Avg(), etc. that need to updated for each original row read. Distinct doesn't have to do this... In the special case where you Group By only to get distinct values, (And there are no aggregate columns in output), then it is probably exactly the same query plan.... It would be interesting to review the query execution plan for the two options and see what it did...

Certainly Distinct is the way to go for readability if that is what you are doing (When your purpose is to eliminate duplicate rows, and you are not calculating any aggregate columns)

>>> import numpy
>>> print numpy.power.__doc__

power(x1, x2[, out])

First array elements raised to powers from second array, element-wise.

Raise each base in `x1` to the positionally-corresponding power in
`x2`.  `x1` and `x2` must be broadcastable to the same shape.

Parameters
----------
x1 : array_like
    The bases.
x2 : array_like
    The exponents.

Returns
-------
y : ndarray
    The bases in `x1` raised to the exponents in `x2`.

Examples
--------
Cube each element in a list.

>>> x1 = range(6)
>>> x1
[0, 1, 2, 3, 4, 5]
>>> np.power(x1, 3)
array([  0,   1,   8,  27,  64, 125])

Raise the bases to different exponents.

>>> x2 = [1.0, 2.0, 3.0, 3.0, 2.0, 1.0]
>>> np.power(x1, x2)
array([  0.,   1.,   8.,  27.,  16.,   5.])

The effect of broadcasting.

>>> x2 = np.array([[1, 2, 3, 3, 2, 1], [1, 2, 3, 3, 2, 1]])
>>> x2
array([[1, 2, 3, 3, 2, 1],
       [1, 2, 3, 3, 2, 1]])
>>> np.power(x1, x2)
array([[ 0,  1,  8, 27, 16,  5],
       [ 0,  1,  8, 27, 16,  5]])

Precision

As per the discussed observation on numerical precision as per @GarethRees objection in comments:

>>> a = numpy.ones( (3,3), dtype = numpy.float96 ) # yields exact output
>>> a[0,0] = 0.46002700024131926
>>> a
array([[ 0.460027,  1.0,  1.0],
       [ 1.0,  1.0,  1.0],
       [ 1.0,  1.0,  1.0]], dtype=float96)
>>> b = numpy.power( a, 2 )
>>> b
array([[ 0.21162484,  1.0,  1.0],
       [ 1.0,  1.0,  1.0],
       [ 1.0,  1.0,  1.0]], dtype=float96)

>>> a.dtype
dtype('float96')
>>> a[0,0]
0.46002700024131926
>>> b[0,0]

Performance

>>> c    = numpy.random.random( ( 1000, 1000 ) ).astype( numpy.float96 )

>>> import zmq
>>> aClk = zmq.Stopwatch()

>>> aClk.start(), c**2, aClk.stop()
(None, array([[ ...]], dtype=float96), 5663L)                #   5 663 [usec]

>>> aClk.start(), c*c, aClk.stop()
(None, array([[ ...]], dtype=float96), 6395L)                #   6 395 [usec]

Or you can use what JQuery alreay made for you:

http://jqueryui.com/datepicker/#icon-trigger

It's what you are trying to achieve isn't it?

This is what I would use:

a. Make sure to use double quotes, for example:

$row['message'] = "This is   a Text \n and so on \t     Text text.";

b. To remove extra whitespace, use:

$ro = preg_replace('/\s+/', ' ', $row['message']); 
echo $ro;

It may not be the fastest solution, but I think it will require the least code, and it should work. I've never used mysql, though, so I may be wrong.

• Update the Android SDK to latest version

• Update app/build.gradle with latest components:

  compileSdkVersion 25  
  buildToolsVersion "25.0.2"  
  minSdkVersion 17  
  targetSdkVersion 25
  

Hope this solves your problem

This is the approach to do this: -

1. Check whether the table or column exists or not.
2. If yes, then alter the column. e.g:-

IF EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE 
            TABLE_CATALOG = 'DBName' AND 
            TABLE_SCHEMA = 'SchemaName' AND
            TABLE_NAME = 'TableName' AND
            COLUMN_NAME = 'ColumnName')
BEGIN
    ALTER TABLE DBName.SchemaName.TableName ALTER COLUMN ColumnName [data type] NULL
END  

If you don't have any schema then delete the schema line because you don't need to give the default schema.

I had this problem resolved. Aparently that message is used in multiple error types. My problem was that i had reached my maximum of 500 sent mails.

log into the account and manually try to send a mail. If the limit has been reached it will inform you

Try python-request or python-grab

<a href="<?php echo $_SERVER['DOCUMENT_ROOT'].'/hello.html'; ?>">go with php</a>
    <br />
<a href="/hello.html">go to with html</a>

Try this yourself and find that they are not exactly the same.

$_SERVER['DOCUMENT_ROOT'] renders an actual file path (on my computer running as it's own server, C:/wamp/www/

HTML's / renders the root of the server url, in my case, localhost/

But C:/wamp/www/hello.html and localhost/hello.html are in fact the same file

Just u can use with using System.Linq;

List<string> stringList = line.Split(',')     // this is array
 .ToList();     // this is a list which you can loop in all split string

line2 = "hello 12 hi 89"
temp1 = re.findall(r'\d+', line2) # through regular expression
res2 = list(map(int, temp1))
print(res2)

Hi ,

you can search all the integers in the string through digit by using findall expression .

In the second step create a list res2 and add the digits found in string to this list

hope this helps

Java commons-io has a FileAlterationObserver. it does polling in combination with a FileAlterationMonitor. Similar to commons VFS. The advantag is that it has much less dependencies.

edit: Less dependencies is not true, they are optional for VFS. But it uses java File instead of the VFS abstraction layer.

Select all text afected by this issue:

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

WHERE L.OBJECT_ID = O.OBJECT_ID 
AND L.SESSION_ID = S.SID AND S.PADDR = P.ADDR 
AND S.SQL_ADDRESS = SQ.ADDRESS;

The importance of the double quotes is worth emphasizing. Suppose an argument contains whitespace.

Code:

#!/bin/bash
printf 'arguments:%s\n' "$@"
declare -a arrayGOOD=( "$@" )
declare -a arrayBAAD=(  $@  )

printf '\n%s:\n' arrayGOOD
declare -p arrayGOOD
arrayGOODlength=${#arrayGOOD[@]}
for (( i=1; i<${arrayGOODlength}+1; i++ ));
do
   echo "${arrayGOOD[$i-1]}"

printf '\n%s:\n' arrayBAAD
declare -p arrayBAAD
arrayBAADlength=${#arrayBAAD[@]}
for (( i=1; i<${arrayBAADlength}+1; i++ ));
do
   echo "${arrayBAAD[$i-1]}"
done

Output:

For HTML 4, the answer is technically:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

HTML 5 is even more permissive, saying only that an id must contain at least one character and may not contain any space characters.

The id attribute is case sensitive in XHTML.

As a purely practical matter, you may want to avoid certain characters. Periods, colons and '#' have special meaning in CSS selectors, so you will have to escape those characters using a backslash in CSS or a double backslash in a selector string passed to jQuery. Think about how often you will have to escape a character in your stylesheets or code before you go crazy with periods and colons in ids.

For example, the HTML declaration <div id="first.name"></div> is valid. You can select that element in CSS as #first\.name and in jQuery like so: $('#first\\.name'). But if you forget the backslash, $('#first.name'), you will have a perfectly valid selector looking for an element with id first and also having class name. This is a bug that is easy to overlook. You might be happier in the long run choosing the id first-name (a hyphen rather than a period), instead.

You can simplify your development tasks by strictly sticking to a naming convention. For example, if you limit yourself entirely to lower-case characters and always separate words with either hyphens or underscores (but not both, pick one and never use the other), then you have an easy-to-remember pattern. You will never wonder "was it firstName or FirstName?" because you will always know that you should type first_name. Prefer camel case? Then limit yourself to that, no hyphens or underscores, and always, consistently use either upper-case or lower-case for the first character, don't mix them.

A now very obscure problem was that at least one browser, Netscape 6, incorrectly treated id attribute values as case-sensitive. That meant that if you had typed id="firstName" in your HTML (lower-case 'f') and #FirstName { color: red } in your CSS (upper-case 'F'), that buggy browser would have failed to set the element's color to red. At the time of this edit, April 2015, I hope you aren't being asked to support Netscape 6. Consider this a historical footnote.

Alternatively you could just use a document.write:

<script type="text\javascript">
var loc = "http://";
document.write('<a href="' + loc + '">Link text</a>');
</script>

All these work:

#include <iostream>
using namespace std;

//Good, because manual memory management isn't needed and this uses
//less heap memory (or no heap memory) so this is safer if
//used in a low memory situation
void f() { throw string("foo"); }

//Valid, but avoid manual memory management if there's no reason to use it
void g() { throw new string("foo"); }

//Best.  Just a pointer to a string literal, so no allocation is needed,
//saving on cleanup, and removing a chance for an allocation to fail.
void h() { throw "foo"; }

int main() {
  try { f(); } catch (string s) { cout << s << endl; }
  try { g(); } catch (string* s) { cout << *s << endl; delete s; }
  try { h(); } catch (const char* s) { cout << s << endl; }
  return 0;
}

You should prefer h to f to g. Note that in the least preferable option you need to free the memory explicitly.

Here is a simple instruction:

1) Install:

nvm install 8.10.0

2) Use once per terminal

nvm use 8.10.0

3) Set up as default for all terminals

nvm alias default 8.10.0

You may need to use root permissions to perform those actions.

And don't forget to check nvm documentation for more info.

Also note that you may need to specify node version for your IDE:

I would recommend using jQuery with this function:

$(document).ready(function(){
 $('#about').addClass('expand');
});

This will add the expand class to an element with id of about when the dom is ready on page load.

You should not pass the call function hi() to the loop() function, This will give the result.

def hi():     
  print('hi')

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)            # Do not use hi() function inside loop() function

tl;dr

Use only modern java.time classes. Never use the terrible legacy classes such as SimpleDateFormat, Date, or java.sql.Timestamp.

ZonedDateTime                    // Represent a moment as perceived in the wall-clock time used by the people of a particular region ( a time zone).
.now(                            // Capture the current moment.
    ZoneId.of( "Africa/Tunis" )  // Specify the time zone using proper Continent/Region name. Never use 3-4 character pseudo-zones such as PDT, EST, IST. 
)                                // Returns a `ZonedDateTime` object. 
.format(                         // Generate a `String` object containing text representing the value of our date-time object. 
    DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" )
)                                // Returns a `String`. 

Or use the JVM’s current default time zone.

ZonedDateTime
.now( ZoneId.systemDefault() )
.format( DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" ) )

java.time & JDBC 4.2

The modern approach uses the java.time classes as seen above.

If your JDBC driver complies with JDBC 4.2, you can directly exchange java.time objects with the database. Use PreparedStatement::setObject and ResultSet::getObject.

Use java.sql only for drivers before JDBC 4.2

If your JDBC driver does not yet comply with JDBC 4.2 for support of java.time types, you must fall back to using the java.sql classes.

Storing data.

OffsetDateTime odt = OffsetDateTime.now( ZoneOffset.UTC ) ;  // Capture the current moment in UTC.
myPreparedStatement.setObject( … , odt ) ;

Retrieving data.

OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;

The java.sql types, such as java.sql.Timestamp, should only be used for transfer in and out of the database. Immediately convert to java.time types in Java 8 and later.

java.time.Instant

A java.sql.Timestamp maps to a java.time.Instant, a moment on the timeline in UTC. Notice the new conversion method toInstant added to the old class.

java.sql.Timestamp ts = myResultSet.getTimestamp( … );
Instant instant = ts.toInstant(); 

Time Zone

Apply the desired/expected time zone (ZoneId) to get a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Formatted Strings

Use a DateTimeFormatter to generate your string. The pattern codes are similar to those of java.text.SimpleDateFormat but not exactly, so read the doc carefully.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern( "uuuu.MM.dd.HH.mm.ss" );
String output = zdt.format( formatter );

This particular format is ambiguous as to its exact meaning as it lacks any indication of offset-from-UTC or time zone.

ISO 8601

If you have any say in the matter, I suggest you consider using standard ISO 8601 formats rather than rolling your own. The standard format is quite similar to yours. For example:
2016-02-20T03:26:32+05:30.

The java.time classes use these standard formats by default, so no need to specify a pattern. The ZonedDateTime class extends the standard format by appending the name of the time zone (a wise improvement).

String output = zdt.toString(); // Example: 2007-12-03T10:15:30+01:00[Europe/Paris]

Convert to java.sql

You can convert from java.time back to java.sql.Timestamp. Extract an Instant from the ZonedDateTime.

New methods have been added to the old classes to facilitate converting to/from java.time classes.

java.sql.Timestamp ts = java.sql.Timestamp.from( zdt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
• Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
• Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
• Later versions of Android bundle implementations of the java.time classes.
• For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

I have to pass two parameters like:

/Controller/Action/Param1Value/Param2Value

This way:

@Html.ActionLink(
    linkText,
    actionName,
    controllerName,
    routeValues: new {
        Param1Name= Param1Value, 
        Param2Name = Param2Value 
    },
    htmlAttributes: null
)

will generate this url

/Controller/Action/Param1Value?Param2Name=Param2Value

I used a workaround method by merging parameter two in parameter one and I get what I wanted:

@Html.ActionLink(
    linkText,
    actionName,
    controllerName,
    routeValues: new {
        Param1Name= "Param1Value / Param2Value" ,      
    },
    htmlAttributes: null
)

And I get :

/Controller/Action/Param1Value/Param2Value

Based on the answers and comments given by Klass and Kevin Ballard above, I would go with:

println(_stdlib_getDemangledTypeName(now).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(soon).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(soon?).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(soon!).componentsSeparatedByString(".").last!)

println(_stdlib_getDemangledTypeName(myvar0).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(myvar1).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(myvar2).componentsSeparatedByString(".").last!)
println(_stdlib_getDemangledTypeName(myvar3).componentsSeparatedByString(".").last!)

which will print out:

"NSDate"
"ImplicitlyUnwrappedOptional"
"Optional"
"NSDate"

"NSString"
"PureSwiftClass"
"Int"
"Double"

• Just for another example of Scanner.next() and nextLine() is that like below : nextLine() does not let user type while next() makes Scanner wait and read the input.

   Scanner sc = new Scanner(System.in);
  
   do {
      System.out.println("The values on dice are :");
      for(int i = 0; i < n; i++) {
          System.out.println(ran.nextInt(6) + 1);
      }
      System.out.println("Continue : yes or no");
   } while(sc.next().equals("yes"));
  // while(sc.nextLine().equals("yes"));
  

If you wanted to do it that way...

$line = 0;

while (($buffer = fgets($fh)) !== FALSE) {
   if ($line == 1) {
       // This is the second line.
       break;
   }   
   $line++;
}

Alternatively, open it with file() and subscript the line with [1].

UPDATE -- use this instead:

<script type="text/babel" src="./lander.js"></script>

Add type="text/jsx" as an attribute of the script tag used to include the JavaScript file that must be transformed by JSX Transformer, like that:

<script type="text/jsx" src="./lander.js"></script>

Then you can use MAMP or some other service to host the page on localhost so that all of the inclusions work, as discussed here.

Thanks for all the help everyone!

Use of sort can result in warning message. See github discussion. So you might wanna use sort_values, docs here

Then your code can look like this:

df = df.sort_values(by=['c1','c2'], ascending=[False,True])

Need to add to chosen answer: As of now, npm install in a package directory (containing package.json) will install devDependencies, whereas npm install -g will not install them.

I had the following problem:
I had a Android phone without drivers, and it could not be recognized by the Windows 8.1. Neither as phone, neither as USB storage device.

I searched Device manager.
I opened Device manager, I right click on Android Phone->Android Composite Interface.
I selected "Update Driver Software"
I choose "Browse My Computer for Driver Software"
Then I choose "Let me pick from a list of devices"
I selected "USB Composite Device"

A new USB device is added to the list, and I can connect to my phone using adb and Android SDK.

Also I can use the phone as storage device.
Good luck

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

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

On a Mac, the "most efficient" way to install jq would probably be using homebrew, e.g.

brew install jq

If you want the development version, you could try:

brew install --HEAD jq

but this has various pre-requisites.

Detailed instructions are on the "Installation" page of the jq wiki: https://github.com/stedolan/jq/wiki/Installation

The same page also includes details regarding installation from source, and has notes on installing with MacPorts.

simplest way to center your div element is to use this class with following properties.

.light {
    margin: auto;
    width: 50%;
    border: 3px solid green;
    padding: 10px;
}

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

in your <head>

<meta id="viewport"
      name="viewport"
      content="width=1024, height=768, initial-scale=0, minimum-scale=0.25" />

somewhere in your javascript

document.getElementById("viewport").setAttribute("content",
      "initial-scale=0.5; maximum-scale=1.0; user-scalable=0;");

Riffing on @Mark answer above, added the @updateusage='true' to force the latest size stats (https://msdn.microsoft.com/en-us/library/ms188776.aspx):

        SET NOCOUNT ON
        DECLARE @TableInfo TABLE (tablename varchar(255), rowcounts int, reserved varchar(255), DATA varchar(255), index_size varchar(255), unused varchar(255))
        DECLARE @cmd1 varchar(500)
        SET @cmd1 = 'exec sp_spaceused @objname =''?'', @updateusage =''true'' '

        INSERT INTO @TableInfo (tablename,rowcounts,reserved,DATA,index_size,unused)
        EXEC sp_msforeachtable @command1=@cmd1 
SELECT * FROM @TableInfo ORDER BY Convert(int,Replace(DATA,' KB','')) DESC

In case someone also want to dump response like me. i avoided to dump response body. following code just dump the StatusCode and Headers.

static private String dumpResponse(HttpServletResponse resp){
    StringBuilder sb = new StringBuilder();

    sb.append("Response Status = [" + resp.getStatus() + "], ");
    String headers = resp.getHeaderNames().stream()
                    .map(headerName -> headerName + " : " + resp.getHeaders(headerName) )
                    .collect(Collectors.joining(", "));

    if (headers.isEmpty()) {
        sb.append("Response headers: NONE,");
    } else {
        sb.append("Response headers: "+headers+",");
    }

    return sb.toString();
}

z-index only works on absolute or relatively positioned elements. I would use an outer div set to position relative. Set the div on top to position absolute to remove it from the flow of the document.

_x000D_
.front {_x000D_
  border:3px solid #c00;_x000D_

  width:300px;_x000D_
  position:absolute;_x000D_
  z-index:10;_x000D_
  top:30px;_x000D_
  left:50px;_x000D_
 }_x000D_
  _x000D_
.behind {background-color:#ccc;}

If you don't want to jQuery, here's the vanilla JavaScript:

///Mute
var video = document.getElementById("your-video-id");
video.muted= true;

//Unmute
var video = document.getElementById("your-video-id");
video.muted= false;

It will work for audio too, just put the element's id and it will work (and change the var name if you want, to 'media' or something suited for both audio/video as you like).

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

A. Make sure your other activity is declared in manifest:

<activity
    android:name="MyOtherActivity"
    android:label="@string/app_name">
</activity>

All activities must be declared in manifest, even if they do not have an intent filter assigned to them.

B. In your MainActivity do something like this:

Button btn = (Button)findViewById(R.id.open_activity_button);    

btn.setOnClickListener(new View.OnClickListener() {         
        @Override
        public void onClick(View v) {
            startActivity(new Intent(MainActivity.this, MyOtherActivity.class));
        }
});

This only converts the tabs without changing anything else:
