You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

Use:

$( '#form' ).serializeArray();

Php get array, dont need unserialize ;)

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

I would style a link to look like a button, because that way there is a no-js fallback.

So this is how you could animate the jump using jquery. No-js fallback is a normal jump without animation.

Original example:

jsfiddle

$(document).ready(function() {_x000D_
  $(".jumper").on("click", function( e ) {_x000D_
_x000D_
    e.preventDefault();_x000D_
_x000D_
    $("body, html").animate({ _x000D_
      scrollTop: $( $(this).attr('href') ).offset().top _x000D_
    }, 600);_x000D_
_x000D_
  });_x000D_
});

#long {_x000D_
  height: 500px;_x000D_
  background-color: blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<!-- Links that trigger the jumping -->_x000D_
<a class="jumper" href="#pliip">Pliip</a>_x000D_
<a class="jumper" href="#ploop">Ploop</a>_x000D_
<div id="long">...</div>_x000D_
<!-- Landing elements -->_x000D_
<div id="pliip">pliip</div>_x000D_
<div id="ploop">ploop</div>

New example with actual button styles for the links, just to prove a point.

Everything is essentially the same, except that I changed the class .jumper to .button and I added css styling to make the links look like buttons.

Button styles example

To remove it from all inputs

input {
 outline:none;
}

Actually, if you have a list of n elements, and create a binary tree from that list (like in the divide and conquer algorithm), you will keep dividing by 2 until you reach lists of size 1 (the leaves).

At the first step, you divide by 2. You then have 2 lists (2^1), you divide each by 2, so you have 4 lists (2^2), you divide again, you have 8 lists (2^3)and so on until your list size is 1

That gives you the equation :

n/(2^steps)=1 <=> n=2^steps <=> lg(n)=steps

(you take the lg of each side, lg being the log base 2)

Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string,

using Microsoft.AspNet.Identity;

int userId = User.Identity.GetUserId<int>();

will do the trick

Use @title in your controllers when you want your variable to be available in your views.

The explanation is that @title is an instance variable while title is a local variable. Rails makes instance variables from controllers available to views because the template code (erb, haml, etc) is executed within the scope of the current controller instance.

You could specify the width of all but the last table cells and add a table-layout:fixed and a width to the table.

You could set

table tr ul.actions {margin: 0; white-space:nowrap;}

(or set this for the last TD as Sander suggested instead).

This forces the inline-LIs not to break. Unfortunately this does not lead to a new width calculation in the containing UL (and this parent TD), and therefore does not autosize the last TD.

This means: if an inline element has no given width, a TD's width is always computed automatically first (if not specified). Then its inline content with this calculated width gets rendered and the white-space-property is applied, stretching its content beyond the calculated boundaries.

So I guess it's not possible without having an element within the last TD with a specific width.

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

On macos, configure python 3.8.1 with the command below will solve the problem, i think it would also work on Linux.

./configure --enable-optimizations --with-openssl=/usr/local/opt/[email protected]/

change the dir parameter based on your system.

As a follow-up to the answer of @maciej-bukowski above ^^^, in modern browsers as of now (spring 2017) that support async/await you can load as follows. In this example we load the load html2canvas library:

async function loadScript(url) {_x000D_
  let response = await fetch(url);_x000D_
  let script = await response.text();_x000D_
  eval(script);_x000D_
}_x000D_
_x000D_
let scriptUrl = 'https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js'_x000D_
loadScript(scriptUrl);

If you run the snippet and then open your browser's console you should see the function html2canvas() is now defined.

I had a very similar requirement (importing a base64 encoded image from an external xml import file. After using xml2json-light library to convert to a json object, I was able to leverage insight from cuixiping's answer above to convert the incoming b64 encoded image to a file object.

const imgName = incomingImage['FileName'];
const imgExt = imgName.split('.').pop();
let mimeType = 'image/png';
if (imgExt.toLowerCase() !== 'png') {
    mimeType = 'image/jpeg';
}
const imgB64 = incomingImage['_@ttribute'];
const bstr = atob(imgB64);
let n = bstr.length;
const u8arr = new Uint8Array(n);
while (n--) {
  u8arr[n] = bstr.charCodeAt(n);
}
const file = new File([u8arr], imgName, {type: mimeType});

My incoming json object had two properties after conversion by xml2json-light: FileName and _@ttribute (which was b64 image data contained in the body of the incoming element.) I needed to generate the mime-type based on the incoming FileName extension. Once I had all the pieces extracted/referenced from the json object, it was a simple task (using cuixiping's supplied code reference) to generate the new File object which was completely compatible with my existing classes that expected a file object generated from the browser element.

Hope this helps connects the dots for others.

Here a single example using Duration and TimeUnit to get 'hh:mm:ss' format.

Duration dur = Duration.between(localDateTimeIni, localDateTimeEnd);
long millis = dur.toMillis();

String.format("%02d:%02d:%02d", 
        TimeUnit.MILLISECONDS.toHours(millis),
        TimeUnit.MILLISECONDS.toMinutes(millis) - 
        TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
        TimeUnit.MILLISECONDS.toSeconds(millis) - 
        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

While the answers with List<T>.ForEach are very good.

I found String.Join<T>(string separator, IEnumerable<T> values) method more useful.

Example :

List<string> numbersStrLst = new List<string>
            { "One", "Two", "Three","Four","Five"};

Console.WriteLine(String.Join(", ", numbersStrLst));//Output:"One, Two, Three, Four, Five"

int[] numbersIntAry = new int[] {1, 2, 3, 4, 5};
Console.WriteLine(String.Join("; ", numbersIntAry));//Output:"1; 2; 3; 4; 5"

Remarks :

If separator is null, an empty string (String.Empty) is used instead. If any member of values is null, an empty string is used instead.

Join(String, IEnumerable<String>) is a convenience method that lets you concatenate each element in an IEnumerable(Of String) collection without first converting the elements to a string array. It is particularly useful with Language-Integrated Query (LINQ) query expressions.

This should work just fine for the problem, whereas for others, having array values. Use other overloads of this same method, String.Join Method (String, Object[])

Thought I'd add an answer since your question title looks like it is asking how to create or update, rather than get or create as described in the question body.

If you did want to create or update an object, the .save() method already has this behaviour by default, from the docs:

Django abstracts the need to use INSERT or UPDATE SQL statements. Specifically, when you call save(), Django follows this algorithm:

If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.

It's worth noting that when they say 'if the UPDATE didn't update anything' they are essentially referring to the case where the id you gave the object doesn't already exist in the database.

Here is where the repair button is:

Use the XML Tools plugin for Notepad++ and then you can Auto-Indent the code with Ctrl+Alt+Shift+B .For the more point-and-click inclined, you could also go to Plugins --> XML Tools --> Pretty Print.

I remember my CompSci professor saying never to use floats for currency.

The reason for that is how the IEEE specification defines floats in binary format. Basically, it stores sign, fraction and exponent to represent a Float. It's like a scientific notation for binary (something like +1.43*10^2). Because of that, it is impossible to store fractions and decimals in Float exactly.

That's why there is a Decimal format. If you do this:

irb:001:0> "%.47f" % (1.0/10)
=> "0.10000000000000000555111512312578270211815834045" # not "0.1"!

whereas if you just do

irb:002:0> (1.0/10).to_s
=> "0.1" # the interprer rounds the number for you

So if you are dealing with small fractions, like compounding interests, or maybe even geolocation, I would highly recommend Decimal format, since in decimal format 1.0/10 is exactly 0.1.

However, it should be noted that despite being less accurate, floats are processed faster. Here's a benchmark:

require "benchmark" 
require "bigdecimal" 

d = BigDecimal.new(3) 
f = Float(3)

time_decimal = Benchmark.measure{ (1..10000000).each { |i| d * d } } 
time_float = Benchmark.measure{ (1..10000000).each { |i| f * f } }

puts time_decimal 
#=> 6.770960 seconds 
puts time_float 
#=> 0.988070 seconds

Answer

Use float when you don't care about precision too much. For example, some scientific simulations and calculations only need up to 3 or 4 significant digits. This is useful in trading off accuracy for speed. Since they don't need precision as much as speed, they would use float.

Use decimal if you are dealing with numbers that need to be precise and sum up to correct number (like compounding interests and money-related things). Remember: if you need precision, then you should always use decimal.

All the previous posts bring valid points, but some don't answer the question precisely.

The question is: Why would someone prefer money when we already know it is a less precise data type and can cause errors if used in complex calculations?

You use money when you won't make complex calculations and can trade this precision for other needs.

For example, when you don't have to make those calculations, and need to import data from valid currency text strings. This automatic conversion works only with MONEY data type:

SELECT CONVERT(MONEY, '$1,000.68')

I know you can make your own import routine. But sometimes you don't want to recreate a import routine with worldwide specific locale formats.

Another example, when you don't have to make those calculations (you need just to store a value) and need to save 1 byte (money takes 8 bytes and decimal(19,4) takes 9 bytes). In some applications (fast CPU, big RAM, slow IO), like just reading huge amount of data, this can be faster too.

For :

abc:number|string;

Use the JavaScript operator typeof:

if (typeof abc === "number") {
    // do something
}

TypeScript understands typeof

This is called a typeguard.

For classes you would use instanceof e.g.

class Foo {}
class Bar {} 

// Later
if (fooOrBar instanceof Foo){
  // TypeScript now knows that `fooOrBar` is `Foo`
}

There are also other type guards e.g. in etc https://basarat.gitbooks.io/typescript/content/docs/types/typeGuard.html

I'd suggest doing something similar to:

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = parent.getElementsByClassName('sub');
        if (sub[0].style.display == 'inline'){
            sub[0].style.display = 'none';
        }
        else {
            sub[0].style.display = 'inline';
        }
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this.id);
};????

JS Fiddle demo.

Though the above relies on the use of a class rather than a name attribute equal to sub.

As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:

Uncaught TypeError: Object # has no method 'getElementsByName'.

One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName(), albeit crudely:

function eBCN(elem,classN){
    if (!elem || !classN){
        return false;
    }
    else {
        var children = elem.childNodes;
        for (var i=0,len=children.length;i<len;i++){
            if (children[i].nodeType == 1
                &&
                children[i].className == classN){
                    var sub = children[i];
            }
        }
        return sub;
    }
}

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = eBCN(parent,'sub');
        if (sub.style.display == 'inline'){
            sub.style.display = 'none';
        }
        else {
            sub.style.display = 'inline';
        }
    }
}

var D = document,
    listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
    listElems[i].onclick = function(){
        show_sub(this.id);
    };
}?

As an addition to user1471935's suggestion:

To instantiate a generic class by using a constructor with one or more parameters, you can now use the Activator class.

T instance = Activator.CreateInstance(typeof(T), new object[] {...}) 

The list of objects are the parameters you want to supply. According to Microsoft:

CreateInstance [...] creates an instance of the specified type using the constructor that best matches the specified parameters.

There's also a generic version of CreateInstance (CreateInstance<T>()) but that one also does not allow you to supply constructor parameters.

JSON in any HTML tag except <script> tag would be a mere text. Thus it's like you add a story to your HTML page.

However, about formatting, that's another matter. I guess you should change the title of your question.

The other answers mostly use the flags for setSystemUiVisibility() method in View. However, this API is deprecated since Android 11. Check my article about modifying the system UI visibility for more information. The article also explains how to handle the cutouts properly or how to listen to the visibility changes.

Here are code snippets for showing / hiding system bars with the new API as well as the deprecated one for backward compatibility:

I found that the formal way to do this is as follows:

Just install two (or more, using their installers) versions of Python on Windows 7 (for me work with 3.3 and 2.7).

Follow the instuctions below, changing the parameters for your needs.

Create the following environment variable (to default on double click):

Name:  PY_PYTHON
Value: 3

To launch a script in a particular interpreter, add the following shebang (beginning of script):

#! python2

To execute a script using a specific interpreter, use the following prompt command:

> py -2 MyScript.py

To launch a specific interpreter:

> py -2

To launch the default interpreter (defined by the PY_PYTHON variable):

> py

Using DevTools in the latest Chrome (v29) I find these two tips very helpful for debugging events:

1. Listing jQuery events of the last selected DOM element

   • Inspect an element on the page
   • type the following in the console:

     $._data($0, "events") //assuming jQuery 1.7+

   • It will list all jQuery event objects associated with it, expand the interested event, right-click on the function of the "handler" property and choose "Show function definition". It will open the file containing the specified function.

2. Utilizing the monitorEvents() command

What you could do is, a validation of the values, for example:

if the value of the input of fullanme is greater than some value length and if the value of the input of address is greater than some value length then redirect to a new page, otherwise shows an error for the input.

// We access to the inputs by their id's
let fullname = document.getElementById("fullname");
let address = document.getElementById("address");

// Error messages
let errorElement = document.getElementById("name_error");
let errorElementAddress = document.getElementById("address_error");

// Form
let contactForm = document.getElementById("form");

// Event listener
contactForm.addEventListener("submit", function (e) {
  let messageName = [];
  let messageAddress = [];
  
    if (fullname.value === "" || fullname.value === null) {
    messageName.push("* This field is required");
  }

  if (address.value === "" || address.value === null) {
    messageAddress.push("* This field is required");
  }

  // Statement to shows the errors
  if (messageName.length || messageAddress.length > 0) {
    e.preventDefault();
    errorElement.innerText = messageName;
    errorElementAddress.innerText = messageAddress;
  }
  
   // if the values length is filled and it's greater than 2 then redirect to this page
    if (
    (fullname.value.length > 2,
    address.value.length > 2)
  ) {
    e.preventDefault();
    window.location.assign("https://www.google.com");

The ErrorDocument directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot. In your case, this means that the actual path to the ErrorDocument is

ErrorDocument 404 /hellothere/error/404page.html

Check if your PHP installation works.

Check which php.ini file you are running in Apache's configuration and use it to run php.exe...

The best practice is to reference the WSDL and use it like a web service reference. It's easier and works better, but if you don't have the WSDL, the XSD definitions are a good piece of code.

According the W3Schools you might use JavaScript for disabled checkbox.

<!-- Checkbox who determine if the other checkbox must be disabled -->
<input type="checkbox" id="checkboxDetermine">
<!-- The other checkbox conditionned by the first checkbox -->
<input type="checkbox" id="checkboxConditioned">
<!-- JS Script -->
<script type="text/javascript">
    // Get your checkbox who determine the condition
    var determine = document.getElementById("checkboxDetermine");
    // Make a function who disabled or enabled your conditioned checkbox
    var disableCheckboxConditioned = function () {
        if(determine.checked) {
            document.getElementById("checkboxConditioned").disabled = true;
        }
        else {
            document.getElementById("checkboxConditioned").disabled = false;
        }
    }
    // On click active your function
    determine.onclick = disableCheckboxConditioned;
    disableCheckboxConditioned();
</script>

So how about .NET Reflector

To the best of my knowledge, JavaScript's objects are garbage collected periodically when there are no references remaining to the object. It is something that happens automatically, but if you want to see more about how it works, at the C++ level, it makes sense to take a look at the WebKit or V8 source code

Typically you don't need to think about it, however, in older browsers, like IE 5.5 and early versions of IE 6, and perhaps current versions, closures would create circular references that when unchecked would end up eating up memory. In the particular case that I mean about closures, it was when you added a JavaScript reference to a dom object, and an object to a DOM object that referred back to the JavaScript object. Basically it could never be collected, and would eventually cause the OS to become unstable in test apps that looped to create crashes. In practice these leaks are usually small, but to keep your code clean you should delete the JavaScript reference to the DOM object.

Usually it is a good idea to use the delete keyword to immediately de-reference big objects like JSON data that you have received back and done whatever you need to do with it, especially in mobile web development. This causes the next sweep of the GC to remove that object and free its memory.

Although this is a very old question and might not be relevant anymore, please keep in mind that most of the problems that the <button> tag used to have don't exist anymore and therefore is highly advisable to use it.

In case you cannot do so for various reasons, just keep in mind to add the attribute role=”button” in your tag as of accessibility. This article is quite informative: https://www.deque.com/blog/accessible-aria-buttons/

I solved it by updating listener.ora file inside oracle directory oraclexe\app\oracle\product\11.2.0\server\network\ADMIN.

Why did it happen to me was because I changed my system name but inside listener.ora there was old name for HOST.

This might be one of the reasons... for those who still face such issue might think of this possibility as well.

This is an excellent article : http://www.daniweb.com/software-development/computer-science/threads/13488/time-complexity-of-algorithm

The below answer is copied from above (in case the excellent link goes bust)

The most common metric for calculating time complexity is Big O notation. This removes all constant factors so that the running time can be estimated in relation to N as N approaches infinity. In general you can think of it like this:

statement;

Is constant. The running time of the statement will not change in relation to N.

for ( i = 0; i < N; i++ )
     statement;

Is linear. The running time of the loop is directly proportional to N. When N doubles, so does the running time.

for ( i = 0; i < N; i++ ) {
  for ( j = 0; j < N; j++ )
    statement;
}

Is quadratic. The running time of the two loops is proportional to the square of N. When N doubles, the running time increases by N * N.

while ( low <= high ) {
  mid = ( low + high ) / 2;
  if ( target < list[mid] )
    high = mid - 1;
  else if ( target > list[mid] )
    low = mid + 1;
  else break;
}

Is logarithmic. The running time of the algorithm is proportional to the number of times N can be divided by 2. This is because the algorithm divides the working area in half with each iteration.

void quicksort ( int list[], int left, int right )
{
  int pivot = partition ( list, left, right );
  quicksort ( list, left, pivot - 1 );
  quicksort ( list, pivot + 1, right );
}

Is N * log ( N ). The running time consists of N loops (iterative or recursive) that are logarithmic, thus the algorithm is a combination of linear and logarithmic.

In general, doing something with every item in one dimension is linear, doing something with every item in two dimensions is quadratic, and dividing the working area in half is logarithmic. There are other Big O measures such as cubic, exponential, and square root, but they're not nearly as common. Big O notation is described as O ( <type> ) where <type> is the measure. The quicksort algorithm would be described as O ( N * log ( N ) ).

Note that none of this has taken into account best, average, and worst case measures. Each would have its own Big O notation. Also note that this is a VERY simplistic explanation. Big O is the most common, but it's also more complex that I've shown. There are also other notations such as big omega, little o, and big theta. You probably won't encounter them outside of an algorithm analysis course. ;)

tl;dr

LocalDate today = LocalDate.now( ZoneId.of( "America/Montreal" ) ) ;
Boolean isBetween = 
    ( ! today.isBefore( localDate1 ) )  // “not-before” is short for “is-equal-to or later-than”.
    &&
    today.isBefore( localDate3 ) ; 

Or, better, if you add the ThreeTen-Extra library to your project.

LocalDateRange.of(
    LocalDate.of( … ) ,
    LocalDate.of( … )
).contains(
    LocalDate.now()
)

Half-open approach, where beginning is inclusive while ending is exclusive.

Bad Choice of Format

By the way, that is a bad choice of format for a text representation of a date or date-time value. Whenever possible, stick with the standard ISO 8601 formats. ISO 8601 formats are unambiguous, understandable across human cultures, and are easy to parse by machine.

For a date-only value, the standard format is YYYY-MM-DD. Note how this format has the benefit of being chronological when sorted alphabetically.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( z );

DateTimeFormatter

As your input strings are non-standard format, we must define a formatting pattern to match.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MM-uuuu" );

Use that to parse the input strings.

LocalDate start = LocalDate.parse( "22-02-2010" , f );
LocalDate stop = LocalDate.parse( "25-12-2010" , f );

In date-time work, usually best to define a span of time by the Half-Open approach where the beginning is inclusive while the ending is exclusive. So we want to know if today is the same or later than the start and also before the stop. A briefer way of saying “is the same or later than the start” is “not before the start”.

Boolean intervalContainsToday = ( ! today.isBefore( start ) ) && today.isBefore( stop ) ;

See the Answer by gstackoverflow showing the list of comparison methods you can call.

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.

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

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

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. Hibernate 5 & JPA 2.2 support java.time.

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 brought 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 (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. 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.

UPDATE: This “Joda-Time” section below is left intact as history. The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

Joda-Time

Other answers are correct with regard to the bundled java.util.Date and java.util.Calendar classes. But those classes are notoriously troublesome. So here's some example code using the Joda-Time 2.3 library.

If you truly want a date without any time portion and no time zone, then use the LocalDate class in Joda-Time. That class provides methods of comparison including compareTo (used with Java Comparators), isBefore, isAfter, and isEqual.

Inputs…

String string1 = "22-02-2010";
String string2 = "07-04-2010";
String string3 = "25-12-2010";

Define a formatter describing the input strings…

DateTimeFormatter formatter = DateTimeFormat.forPattern( "dd-MM-yyyy" );

Use formatter to parse the strings into LocalDate objects…

LocalDate localDate1 = formatter.parseLocalDate( string1 );
LocalDate localDate2 = formatter.parseLocalDate( string2 );
LocalDate localDate3 = formatter.parseLocalDate( string3 );

boolean is1After2 = localDate1.isAfter( localDate2 );
boolean is2Before3 = localDate2.isBefore( localDate3 );

Dump to console…

System.out.println( "Dates: " + localDate1 + " " + localDate2 + " " + localDate3 );
System.out.println( "is1After2 " + is1After2 );
System.out.println( "is2Before3 " + is2Before3 );

When run…

Dates: 2010-02-22 2010-04-07 2010-12-25
is1After2 false
is2Before3 true

So see if the second is between the other two (exclusively, meaning not equal to either endpoint)…

boolean is2Between1And3 = ( ( localDate2.isAfter( localDate1 ) ) && ( localDate2.isBefore( localDate3 ) ) );

Working With Spans Of Time

If you are working with spans of time, I suggest exploring in Joda-Time the classes: Duration, Interval, and Period. Methods such as overlap and contains make comparisons easy.

For text representations, look at the ISO 8601 standard’s:

• duration
  Format: PnYnMnDTnHnMnS
  Example: P3Y6M4DT12H30M5S
  (Means “three years, six months, four days, twelve hours, thirty minutes, and five seconds”)
• interval
  Format: start/end
  Example: 2007-03-01T13:00:00Z/2008-05-11T15:30:00Z

Joda-Time classes can work with strings in both those formats, both as input (parsing) and output (generating strings).

Joda-Time performs comparisons using the Half-Open approach where the beginning of the span is inclusive while the ending is exclusive. This approach is a wise one for handling spans of time. Search StackOverflow for more info.

Something like bool isPM = GetHour() > 11. But if you want to format a date to a string, you shouldn't need to do this yourself. Use the date formatting functions for that.

You are confusing a Mock with a Spy.

In a mock all methods are stubbed and return "smart return types". This means that calling any method on a mocked class will do nothing unless you specify behaviour.

In a spy the original functionality of the class is still there but you can validate method invocations in a spy and also override method behaviour.

What you want is

MyProcessingAgent mockMyAgent = Mockito.spy(MyProcessingAgent.class);

A quick example:

static class TestClass {

    public String getThing() {
        return "Thing";
    }

    public String getOtherThing() {
        return getThing();
    }
}

public static void main(String[] args) {
    final TestClass testClass = Mockito.spy(new TestClass());
    Mockito.when(testClass.getThing()).thenReturn("Some Other thing");
    System.out.println(testClass.getOtherThing());
}

Output is:

Some Other thing

NB: You should really try to mock the dependencies for the class being tested not the class itself.

I wrote with parameters that are predefined

They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:

Alter Procedure [Test]
    @StartDate AS varchar(6) = NULL, 
    @EndDate AS varchar(6) = NULL
AS
...

NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.

Now you can call it without passing any arguments e.g. exec dbo.TEST

Here's a self-sufficient JS function that solves this (and other) problems for most European/US locales (primarily between US/German/Swedish number chunking and formatting ... as in the OP). I think it's an improvement on (and inspired by) Slawa's solution, and has no dependencies.

function realParseFloat(s)
{
    s = s.replace(/[^\d,.-]/g, ''); // strip everything except numbers, dots, commas and negative sign
    if (navigator.language.substring(0, 2) !== "de" && /^-?(?:\d+|\d{1,3}(?:,\d{3})+)(?:\.\d+)?$/.test(s)) // if not in German locale and matches #,###.######
    {
        s = s.replace(/,/g, ''); // strip out commas
        return parseFloat(s); // convert to number
    }
    else if (/^-?(?:\d+|\d{1,3}(?:\.\d{3})+)(?:,\d+)?$/.test(s)) // either in German locale or not match #,###.###### and now matches #.###,########
    {
        s = s.replace(/\./g, ''); // strip out dots
        s = s.replace(/,/g, '.'); // replace comma with dot
        return parseFloat(s);
    }
    else // try #,###.###### anyway
    {
        s = s.replace(/,/g, ''); // strip out commas
        return parseFloat(s); // convert to number
    }
}

            System.out.print("Enter Num" + (i + 1) + ": ");

My quick (very long) one liner based on FNV's Multiply+Xor method:

Tried and tested approach.

or either way.
add or remove the "s" to match your URL.

Indeed SET TEST_VARIABLE=value works for current process only, so SETX is required. A quick example for permanently storing an environment variable at user level.

1. In cmd, SETX TEST_VARIABLE etc. Not applied yet (echo %TEST_VARIABLE% shows %TEST_VARIABLE%,
2. Quick check: open cmd, echo %TEST_VARIABLE% shows etc.
3. GUI check: System Properties -> Advanced -> Environment variables -> User variables for -> you should see Varible TEST_VARIABLE with value etc.

To have an output more similar to the raw console.log(obj) I usually do use console.log('Status: ' + util.inspect(obj)) (JSON is slightly different).

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

The short answer is that not only is static useful, it is pretty well always going to be desired.

First, note that static and constexpr are completely independent of each other. static defines the object's lifetime during execution; constexpr specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr is no longer relevant.

Every variable declared constexpr is implicitly const but const and static are almost orthogonal (except for the interaction with static const integers.)

The C++ object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if principle provided it can prove that no other such object can be observed.

That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr) array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.

On the other hand, a local static const object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.

So you should definitely use static constexpr in your example.

However, there is one case where you wouldn't want to use static constexpr. Unless a constexpr declared object is either ODR-used or declared static, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static, since static is likely to force the object to exist at runtime.

Sometimes you want to truncate to something calendar-based, like year or month. Here's an extension method that lets you choose any resolution.

public enum DateTimeResolution
{
    Year, Month, Day, Hour, Minute, Second, Millisecond, Tick
}

public static DateTime Truncate(this DateTime self, DateTimeResolution resolution = DateTimeResolution.Second)
{
    switch (resolution)
    {
        case DateTimeResolution.Year:
            return new DateTime(self.Year, 1, 1, 0, 0, 0, 0, self.Kind);
        case DateTimeResolution.Month:
            return new DateTime(self.Year, self.Month, 1, 0, 0, 0, self.Kind);
        case DateTimeResolution.Day:
            return new DateTime(self.Year, self.Month, self.Day, 0, 0, 0, self.Kind);
        case DateTimeResolution.Hour:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerHour));
        case DateTimeResolution.Minute:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerMinute));
        case DateTimeResolution.Second:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerSecond));
        case DateTimeResolution.Millisecond:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerMillisecond));
        case DateTimeResolution.Tick:
            return self.AddTicks(0);
        default:
            throw new ArgumentException("unrecognized resolution", "resolution");
    }
}

Try -o "ProxyCommand=nc --proxy HOST:PORT %h %p" for command in question. It worked on OEL6 but need to modify as mentioned for OEL7.

It's for declaring class member variables in PHP4, and is no longer needed. It will work in PHP5, but will raise an E_STRICT warning in PHP from version 5.0.0 up to version 5.1.2, as of when it was deprecated. Since PHP 5.3, var has been un-deprecated and is a synonym for 'public'.

Example usage:

class foo {
    var $x = 'y'; // or you can use public like...
    public $x = 'y'; //this is also a class member variables.
    function bar() {
    }
}

You could embed the '' default in your regex by adding |$:

>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''

Also works with re.search pointed out by others:

>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''

You can use Joshua's solution but I think you need Elts_int <- as.matrix(tmp_int)

Or for loops:

z <- 1 ## Initialize
counter <- 1 ## Initialize
for(y in 1:48) { ## Assuming 48 columns otherwise, swap 48 and 32
for (x in 1:32) {  
z[counter] <- tmp_int[x,y]
counter <- 1 + counter
}
}

z is a 1d vector.

How do I convert ElementTree.Element to a String?

For Python 3:

xml_str = ElementTree.tostring(xml, encoding='unicode')

For Python 2:

xml_str = ElementTree.tostring(xml, encoding='utf-8')

The following is compatible with both Python 2 & 3, but only works for Latin characters:

xml_str = ElementTree.tostring(xml).decode()

Example usage

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
xml_str = ElementTree.tostring(xml).decode()
print(xml_str)

Output:

<Person Name="John" />

Explanation

Despite what the name implies, ElementTree.tostring() returns a bytestring by default in Python 2 & 3. This is an issue in Python 3, which uses Unicode for strings.

In Python 2 you could use the str type for both text and binary data. Unfortunately this confluence of two different concepts could lead to brittle code which sometimes worked for either kind of data, sometimes not. [...]

To make the distinction between text and binary data clearer and more pronounced, [Python 3] made text and binary data distinct types that cannot blindly be mixed together.

^{Source: Porting Python 2 Code to Python 3}

If we know what version of Python is being used, we can specify the encoding as unicode or utf-8. Otherwise, if we need compatibility with both Python 2 & 3, we can use decode() to convert into the correct type.

For reference, I've included a comparison of .tostring() results between Python 2 and Python 3.

ElementTree.tostring(xml)
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml, encoding='unicode')
# Python 3: <Person Name="John" />
# Python 2: LookupError: unknown encoding: unicode

ElementTree.tostring(xml, encoding='utf-8')
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml).decode()
# Python 3: <Person Name="John" />
# Python 2: <Person Name="John" />

Thanks to Martijn Peters for pointing out that the str datatype changed between Python 2 and 3.

Why not use str()?

In most scenarios, using str() would be the "cannonical" way to convert an object to a string. Unfortunately, using this with Element returns the object's location in memory as a hexstring, rather than a string representation of the object's data.

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
print(str(xml))  # <Element 'Person' at 0x00497A80>

JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object or new Array), is as follows:

var obj = {
    'key': 'value',
    'another key': 'another value',
     anUnquotedKey: 'more value!'
};

For arrays it's:

var arr = [
    'value',
    'another value',
    'even more values'
];

If you need objects within objects, that's fine too:

var obj = {
    'subObject': {
        'key': 'value'
    },
    'another object': {
         'some key': 'some value',
         'another key': 'another value',
         'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
    }
}

This convenient method of being able to instantiate static data is what led to the JSON data format.

JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:

{"foo":"bar", "keyWithIntegerValue":123}

As we also get this error when we use s3 NPM package. So the problem is with graceful-fs package we need to take it updated. It is working fine on 4.2.3.

So just look in what NPM package it is showing in logs trace and update the graceful-fs accordingly to 4.2.3.

Try this one. It centers vertically and horizontally.

Center(
  child: Column(
    mainAxisAlignment: MainAxisAlignment.center,
    children: children,
  ),
)

Sorry for the necro answer, but maybe will need this (as I didn't found a solution for recent ffmpeg releases.

With ffmpeg 3.3.4 I found one can find with the following:

ffprobe -i video.mp4 -show_streams -hide_banner | grep "nb_frames"

At the end it will output frame count. It worked for me on videos with audio. It gives twice a "nb_frames" line, though, but the first line was the actual frame count on the videos I tested.

Please try this,

public void removeNotification(Context context, int notificationId) {      
    NotificationManager nMgr = (NotificationManager) context.getApplicationContext()
            .getSystemService(Context.NOTIFICATION_SERVICE);
    nMgr.cancel(notificationId);
}

Close

When you have finished using a socket, you can simply close its file descriptor with close; If there is still data waiting to be transmitted over the connection, normally close tries to complete this transmission. You can control this behavior using the SO_LINGER socket option to specify a timeout period; see Socket Options.

ShutDown

You can also shut down only reception or transmission on a connection by calling shutdown.

The shutdown function shuts down the connection of socket. Its argument how specifies what action to perform: 0 Stop receiving data for this socket. If further data arrives, reject it. 1 Stop trying to transmit data from this socket. Discard any data waiting to be sent. Stop looking for acknowledgement of data already sent; don’t retransmit it if it is lost. 2 Stop both reception and transmission.

The return value is 0 on success and -1 on failure.

code that works, but output is:

10
20
30
40
50

so:

    List<Integer> myCoords = new ArrayList<Integer>();
    myCoords.add(10);
    myCoords.add(20);
    myCoords.add(30);
    myCoords.add(40);
    myCoords.add(50);
    for (Integer number : myCoords) {
        System.out.println(number);
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

For those with a C++ background, you may be interested in a comparison with the C++ equivalent:

class S
{
private: // this is not quite true, in Ruby you can still access these
  static int    k = 23;
  int           s = 15;

public:
  int get_s() { return s; }
  static int get_k() { return k; }

};

std::cerr << S::k() << "\n";

S instance;
std::cerr << instance.s() << "\n";
std::cerr << instance.k() << "\n";

As we can see, k is a static like variable. This is 100% like a global variable, except that it's owned by the class (scoped to be correct). This makes it easier to avoid clashes between similarly named variables. Like any global variable, there is just one instance of that variable and modifying it is always visible by all.

On the other hand, s is an object specific value. Each object has its own instance of the value. In C++, you must create an instance to have access to that variable. In Ruby, the class definition is itself an instance of the class (in JavaScript, this is called a prototype), therefore you can access s from the class without additional instantiation. The class instance can be modified, but modification of s is going to be specific to each instance (each object of type S). So modifying one will not change the value in another.

Simple its works me:)

The problem occurs in declaring context, while using Glide for ImageView or While using intent in recyclerview for item onClick. I Found this working for me which helps me to Declare context to use in Glide or Intent or Toast.

public class NoteAdapter extends FirestoreRecyclerAdapter<Note,NoteAdapter.NoteHolder> {

Context context;

public NoteAdapter(@NonNull FirestoreRecyclerOptions<Note> options) {
    super(options);
}

@Override
protected void onBindViewHolder(@NonNull NoteHolder holder, int position, @NonNull Note model) {
    holder.r_tv.setText(model.getTitle());
    Glide.with(CategoryActivity.context).load(model.getImage()).into(holder.r_iv);

    context = holder.itemView.getContext();

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(context, SuggestActivity.class);
            context.startActivity(i);
        }
    });

}

@NonNull
@Override
public NoteHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_category,parent,false);

    return new NoteHolder(v);
}

Sometimes AutoGenerateBindingRedirects isn't enough (even with GenerateBindingRedirectsOutputType). Searching for all the There was a conflict entries and fixing them manually one by one can be tedious, so I wrote a small piece of code that parses the log output and generates them for you (dumps to stdout):

// Paste all "there was a conflict" lines from the msbuild diagnostics log to the file below
const string conflictFile = @"C:\AssemblyConflicts.txt";

var sb = new StringBuilder();
var conflictLines = await File.ReadAllLinesAsync(conflictFile);
foreach (var line in conflictLines.Where(l => !String.IsNullOrWhiteSpace(l)))
{
    Console.WriteLine("Processing line: {0}", line);

    var lineComponents = line.Split('"');
    if (lineComponents.Length < 2) 
        throw new FormatException("Unexpected conflict line component count");

    var assemblySegment = lineComponents[1];
    Console.WriteLine("Processing assembly segment: {0}", assemblySegment);
    var assemblyComponents = assemblySegment
                              .Split(",")
                              .Select(kv => kv.Trim())
                              .Select(kv => kv.Split("=")
                              .Last())
                              .ToArray();

    if (assemblyComponents.Length != 4) 
        throw new FormatException("Unexpected conflict segment component count");

    var assembly = assemblyComponents[0];
    var version = assemblyComponents[1];
    var culture = assemblyComponents[2];
    var publicKeyToken = assemblyComponents[3];

    Console.WriteLine("Generating assebmly redirect for Assembly={0}, Version={1}, Culture={2}, PublicKeyToken={3}", assembly, version, culture, publicKeyToken);
    sb.AppendLine($"<dependentAssembly><assemblyIdentity name=\"{assembly}\" publicKeyToken=\"{publicKeyToken}\" culture=\"{culture}\" /><bindingRedirect oldVersion=\"0.0.0.0-{version}\" newVersion=\"{version}\" /></dependentAssembly>");
}

Console.WriteLine("Generated assembly redirects:");
Console.WriteLine(sb);

Tip: use MSBuild Binary and Structured Log Viewer and only generate binding redirects for the conflicts in the project that emits the warning (that is, only past those there was a conflict lines to the input text file for the code above [AssemblyConflicts.txt]).

Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Data.SqlClient;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      var builder = new SqlConnectionStringBuilder();
      builder.DataSource = "localhost";
      builder.IntegratedSecurity = true;
      builder.InitialCatalog = "master";

      var connectionString = builder.ConnectionString;

      using (var connection = new SqlConnection(connectionString))
      {
        connection.Open();

        using (var command = connection.CreateCommand())
        {
          command.CommandText = "WAITFOR DELAY '00:00:02'";
          command.CommandTimeout = 1;

          command.ExecuteNonQuery();
        }
      }
    }
  }
}

Use capital HH to get hour of day format, instead of am/pm hours

I'm a bit late to the answer, but you may want to do this if you want the whole element, not only the values you want to group by:

var query = doc.Elements("whatever")
               .GroupBy(element => new {
                             id = (int) element.Attribute("id"),
                             category = (int) element.Attribute("cat") })
               .Select(e => e.First());

This will give you the first whole element matching your group by selection, much like Jon Skeets second example using DistinctBy, but without implementing IEqualityComparer comparer. DistinctBy will most likely be faster, but the solution above will involve less code if performance is not an issue.

just top -bn 1 | grep java will do the trick for you

Why not go even simpler with either one of these options:

$("#box").html('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');

Or, if you want to append it to existing content:

$("#box").append('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');

Note: I put the id="myid" right into the HTML string rather than using separate code to set it.

Both the .html() and .append() jQuery methods can take a string of HTML so there's no need to use a separate step for creating the objects.

In Python 3.4+, you can use the new pathlib package:

from pathlib import Path
for path in Path('.').iterdir():
    print(path)

Path.iterdir() returns an iterator, which can be easily turned into a list:

contents = list(Path('.').iterdir())

format: "YYYY" 

Should be capital instead of "yyyy"

I want to correct little bit the above code

    public class MainActivity extends ActionBarActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
        DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
            this,  mDrawerLayout, mToolbar,
            R.string.navigation_drawer_open, R.string.navigation_drawer_close
        );
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

and all the other things will remain same...

For those who are having problem Drawerlayout overlaying toolbar

add android:layout_marginTop="?attr/actionBarSize" to root layout of drawer content

 using System.Diagnostics;
 class Program
 {
    static void Test1()
    {
        for (int i = 1; i <= 100; i++)
        {
            Console.WriteLine("Test1 " + i);
        }
    }
  static void Main(string[] args)
    {

        Stopwatch sw = new Stopwatch();
        sw.Start();
        Test1();
        sw.Stop();
        Console.WriteLine("Time Taken-->{0}",sw.ElapsedMilliseconds);
   }
 }

As per the documentation: FROM (Transact-SQL):

<join_type> ::= 
    [ { INNER | { { LEFT | RIGHT | FULL } [ OUTER ] } } [ <join_hint> ] ]
    JOIN

The keyword OUTER is marked as optional (enclosed in square brackets). In this specific case, whether you specify OUTER or not makes no difference. Note that while the other elements of the join clause is also marked as optional, leaving them out will make a difference.

For instance, the entire type-part of the JOIN clause is optional, in which case the default is INNER if you just specify JOIN. In other words, this is legal:

SELECT *
FROM A JOIN B ON A.X = B.Y

Here's a list of equivalent syntaxes:

A LEFT JOIN B            A LEFT OUTER JOIN B
A RIGHT JOIN B           A RIGHT OUTER JOIN B
A FULL JOIN B            A FULL OUTER JOIN B
A INNER JOIN B           A JOIN B

Also take a look at the answer I left on this other SO question: SQL left join vs multiple tables on FROM line?.

Go to http://opengapps.org/ and download the pico version of your platform and android version. Unzip the downloaded folder to get
1. GmsCore.apk
2. GoogleServicesFramework.apk
3. GoogleLoginService.apk
4. Phonesky.apk

Then, locate your emulator.exe. You will probably find it in
C:\Users\<YOUR_USER_NAME>\AppData\Local\Android\sdk\tools

Run the command:
emulator -avd <YOUR_EMULATOR'S_NAME> -netdelay none -netspeed full -no-boot-anim -writable-system

Note: Use -writable-system to start your emulator with writable system image.

Then,
adb root
adb remount
adb push <PATH_TO GmsCore.apk> /system/priv-app
adb push <PATH_TO GoogleServicesFramework.apk> /system/priv-app
adb push <PATH_TO GoogleLoginService.apk> /system/priv-app
adb push <PATH_TO Phonesky.apk> /system/priv-app

Then, reboot the emulator
adb shell stop
adb shell start

To verify run,
adb shell pm list packages and you will find com.google.android.gms package for google

According to this website, it's a reference to this, mostly in loops.

$_ (dollar underscore) 'THIS' token. Typically refers to the item inside a foreach loop. Task: Print all items in a collection. Solution. ... | foreach { Write-Host $_ }

public byte UserType
public string SelectUserType

You need to get one and set different one. Selected value can not be the same item that you are about to set.

@Html.DropDownListFor(p => p.SelectUserType, new SelectList(~~UserTypeNames, "Key", "Value",UserType))

I use Enum dictionary for my list, that's why there is "key", "value" pair.

When the text is a number with leading zeros, then do: (Cuando el texto es un número que empieza por ceros, hacer)

$objPHPExcel->getActiveSheet()->setCellValueExplicit('A1', $val,PHPExcel_Cell_DataType::TYPE_STRING);

The spelling?

Seriously though - they're both BS job title fluffing. "Programmer" not good enough for you? Become an "Architect"!

Really... What is the world coming to?!

Edit: I clearly hurt some "architects'" feelings!

Edit 2: Though I agree with the sentiments that the phrasing can be interpreted to mean some people deal with the whole problem domain (eg hardware, software, deployment, maintaining), most people who want to satisfy a client (and make more money) will provide a full service, if required, regardless of their title.

In real life, it's just marketing fluff.

On apache page: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html

You have something like this:

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
    .setParameter("q", "httpclient")
    .setParameter("btnG", "Google Search")
    .setParameter("aq", "f")
    .setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());

First create a temp table :

Step 1:

create table #tblOm_Temp (

    Name varchar(100),
    Age Int ,
    RollNumber bigint
)

**Step 2: ** Insert Some value in Temp table .

insert into #tblom_temp values('Om Pandey',102,1347)

Step 3: Declare a table Variable to hold temp table data.

declare   @tblOm_Variable table(

    Name Varchar(100),
    Age int,
    RollNumber bigint
)

Step 4: select value from temp table and insert into table variable.

insert into @tblOm_Variable select * from #tblom_temp

Finally value is inserted from a temp table to Table variable

Step 5: Can Check inserted value in table variable.

select * from @tblOm_Variable

In Swift 3 use:

yourTextField.frame.size.height = 30

I'm surprised no one had mentioned a simple function that takes a string and a list.

function in_list(needle, hay)
{
    var i, len;

    for (i = 0, len = hay.length; i < len; i++)
    {
        if (hay[i] == needle) { return true; }
    }

    return false;
}

var alist = ["test"];

console.log(in_list("test", alist));

Also, if you set your build target device, the problem will go away when you testing and debugging. The code signed is only need when you trying to deploy your app to an actually physical device

I changed mine from "myIphone" to simulator iPhone 6 Plus, and it solves the problem while I'm developing the app.

Here is an option with only a single comparison.

// return true if in range, otherwise false
function inRange(x, min, max) {
    return ((x-min)*(x-max) <= 0);
}

console.log(inRange(5, 1, 10));     // true
console.log(inRange(-5, 1, 10));    // false
console.log(inRange(20, 1, 10));    // false

you can add security provider by editing java.security by adding security.provider.=org.bouncycastle.jce.provider.BouncyCastleProvider

or add a line in your top of your class

Security.addProvider(new BouncyCastleProvider());

you can use below line to specify provider while specifying algorithms

Cipher cipher = Cipher.getInstance("AES", "SunJCE");

if you are using other provider like Bouncy Castle then

Cipher cipher =  Cipher.getInstance("AES", "BC");

I just saw this as a result of a network error / time-out on a flaky network. I could see the progress bar increasing after I got the bright idea of just retrying. Also saw HTTP Range requests on the download server with ever increasing offsets of a few megabytes (the entire app was about 44MB).

You can use:

<head>
  <meta name="viewport" content="target-densitydpi=device-dpi, initial-scale=1.0, user-scalable=no" />
  ...
</head>

But please note that with Android 4.4 the property target-densitydpi is no longer supported. So for Android 4.4 and later the following is suggested as best practice:

<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no" />

Choice one! But the first is very simple. The last maybe util for file manipulation:

//Method 1 (I like this)
File.AppendAllLines(
    "FileAppendAllLines.txt", 
    new string[] { "line1", "line2", "line3" });

//Method 2
File.AppendAllText(
    "FileAppendAllText.txt",
    "line1" + Environment.NewLine +
    "line2" + Environment.NewLine +
    "line3" + Environment.NewLine);

//Method 3
using (StreamWriter stream = File.AppendText("FileAppendText.txt"))
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

//Method 4
using (StreamWriter stream = new StreamWriter("StreamWriter.txt", true))
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

//Method 5
using (StreamWriter stream = new FileInfo("FileInfo.txt").AppendText())
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

It seems that k8s expects us to provide a different image tag for every deployment. My default strategy would be to make the CI system generate and push the docker images, tagging them with the build number: xpmatteo/foobar:456.

For local development it can be convenient to use a script or a makefile, like this:

# create a unique tag    
VERSION:=$(shell date +%Y%m%d%H%M%S)
TAG=xpmatteo/foobar:$(VERSION)

deploy:
    npm run-script build
    docker build -t $(TAG) . 
    docker push $(TAG)
    sed s%IMAGE_TAG_PLACEHOLDER%$(TAG)% foobar-deployment.yaml | kubectl apply -f - --record

The sed command replaces a placeholder in the deployment document with the actual generated image tag.

This was a bug fixed in version 4.3.11 https://hibernate.atlassian.net/browse/HHH-2851

EDIT: Best way to execute a native query is still to use NamedParameterJdbcTemplate It allows you need to retrieve a result that is not a managed entity ; you can use a RowMapper and even a Map of named parameters!

private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

@Autowired
public void setDataSource(DataSource dataSource) {
    this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}

final List<Long> resultList = namedParameterJdbcTemplate.query(query, 
            mapOfNamedParamters, 
            new RowMapper<Long>() {
        @Override
        public Long mapRow(ResultSet rs, int rowNum) throws SQLException {
            return rs.getLong(1);
        }
    });

This answer does not address the Bash part of the question, but because I tried to use the answers in this question to implement this functionality in Emacs I'll throw it out there.

Emacs actually has a function for this out of the box:

ELISP> (file-relative-name "/a/b/c" "/a/b/c")
"."
ELISP> (file-relative-name "/a/b/c" "/a/b")
"c"
ELISP> (file-relative-name "/a/b/c" "/c/b")
"../../a/b/c"

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

Use the function GetSize from the module cv with your image as parameter. It returns width, height as a tuple with 2 elements:

width, height = cv.GetSize(src)

When the button has a background from the drawable, we can add ripple effect to the foreground parameter.. Check below code its working for my button with a different background

    <Button
    android:layout_width="wrap_content"
    android:layout_height="40dp"
    android:gravity="center"
    android:layout_centerHorizontal="true"                                                             
    android:background="@drawable/shape_login_button"
    android:foreground="?attr/selectableItemBackgroundBorderless"
    android:clickable="true"
    android:text="@string/action_button_login"
     />

Add below parameter for the ripple effect

   android:foreground="?attr/selectableItemBackgroundBorderless"
   android:clickable="true"

For reference refer below link https://jascode.wordpress.com/2017/11/11/how-to-add-ripple-effect-to-an-android-app/

In my case I'm calling an API hosted by AWS (API Gateway). The error happened when I tried to call the API from a domain other than the API own domain. Since I'm the API owner I enabled CORS for the test environment, as described in the Amazon Documentation.

In production this error will not happen, since the request and the api will be in the same domain.

I hope it helps!

One step (IMHO) better

$result .= $personCount . ' people';

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

String str = new String("SOME")

always create a new object on the heap

String str="SOME" 

uses the String pool

Try this small example:

        String s1 = new String("hello");
        String s2 = "hello";
        String s3 = "hello";

        System.err.println(s1 == s2);
        System.err.println(s2 == s3);

To avoid creating unnecesary objects on the heap use the second form.

Inserting 'test' to name will lead to inserting NULL values to other columns of the base table which wont be correct as Id is a PRIMARY KEY and it cannot have NULL value.

No such thing, probably just a macro for int

The following query produces a(nother) query that will get the value of count(*) for every table, from every schema, listed in information_schema.tables. The entire result of the query shown here - all rows taken together - comprise a valid SQL statement ending in a semicolon - no dangling 'union'. The dangling union is avoided by use of a union in the query below.

select concat('select "', table_schema, '.', table_name, '" as `schema.table`,
                          count(*)
                 from ', table_schema, '.', table_name, ' union ') as 'Query Row'
  from information_schema.tables
 union
 select '(select null, null limit 0);';

You don't need to use **arr, you can either use:

void do_something(int el, std::vector<int> *arr){
    arr->push_back(el);
}

or:

 void do_something(int el, std::vector<int> &arr){
    arr.push_back(el);
}

**arr makes no sense but if you insist using it, do it this way:

void do_something(int el, std::vector<int> **arr){
    (*arr)->push_back(el);
}

but again there is no reason to do so...

It took far too long to find this out, but JWebUnit comes bundled with the Logback logging component, so it won't even use log4j.properties or commons-logging.properties.

Instead, create a file called logback.xml and place it in your source code folder (in my case, src):

<configuration debug="false">
  <!-- definition of appender STDOUT -->
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern>
    </encoder>
  </appender>

  <root level="ERROR">
    <!-- appender referenced after it is defined -->
    <appender-ref ref="STDOUT"/>
  </root> 
</configuration>

Logback looks to still be under development and the API seems to still be changing, so this code sample may fail in the future. See also this StackOverflow question.

If keys are nested:

d1 = { 'key1': { 'nkey1': 'x1' }, 'key2': { 'nkey2': 'y1' } } 
d2 = { 'key1': { 'nkey1': 'x2' }, 'key2': { 'nkey2': 'y2' } }

ds = [d1, d2]
d = {}
for k in d1.keys():
    for k2 in d1[k].keys():
        d.setdefault(k, {})
        d[k].setdefault(k2, [])
        d[k][k2] = tuple(d[k][k2] for d in ds)

yields:

{'key1': {'nkey1': ('x1', 'x2')}, 'key2': {'nkey2': ('y1', 'y2')}}

Member functions of the form

operator TypeName()

are conversion operators. They allow objects of the class type to be used as if they were of type TypeName and when they are, they are converted to TypeName using the conversion function.

In this particular case, operator bool() allows an object of the class type to be used as if it were a bool. For example, if you have an object of the class type named obj, you can use it as

if (obj)

This will call the operator bool(), return the result, and use the result as the condition of the if.

It should be noted that operator bool() is A Very Bad Idea and you should really never use it. For a detailed explanation as to why it is bad and for the solution to the problem, see "The Safe Bool Idiom."

(C++0x, the forthcoming revision of the C++ Standard, adds support for explicit conversion operators. These will allow you to write a safe explicit operator bool() that works correctly without having to jump through the hoops of implementing the Safe Bool Idiom.)

I got rid of the problem by unchecking the option for "Alert before overwriting cells" in Excel options. I'm using Excel 2007

As already mentioned this can't be done with floats, they can't inherit heights, they're unaware of their siblings so for example the side two floats don't know the height of the centre content, so they can't inherit from anything.

Usually inherited height has to come from either an element which has an explicit height or if height: 100%; has been passed down through the display tree to it.. The only thing I'm aware of that passes on height which hasn't come from top of the "tree" is an absolutely positioned element - so you could for example absolutely position all the top right bottom left sides and corners (you know the height and width of the corners anyway) And as you seem to know the widths (of left/right borders) and heights of top/bottom) borders, and the widths of the top/bottom centers, are easy at 100% - the only thing that needs calculating is the height of the right/left sides if the content grows -

This you can do, even without using all four positioning co-ordinates which IE6 /7 doesn't support

I've put up an example based on what you gave, it does rely on a fixed width (your frame), but I think it could work with a flexible width too? the uses of this could be cool for those fancy image borders we can't get support for until multiple background images or image borders become fully available.. who knows, I was playing, so just sticking it out there!

proof of concept example is here

Similar to some of the other solutions above, I created an elevate batch file which runs an elevated PowerShell window, bypassing the execution policy to enable running everything from simple commands to batch files to complex PowerShell scripts. I recommend sticking it in your C:\Windows\System32 folder for ease of use.

The original elevate command executes its task, captures the output, closes the spawned PowerShell window and then returns, writing out the captured output to the original window.

I created two variants, elevatep and elevatex, which respectively pause and keep the PowerShell window open for more work.

https://github.com/jt-github/elevate

And in case my link ever dies, here's the code for the original elevate batch file:

@Echo Off
REM Executes a command in an elevated PowerShell window and captures/displays output
REM Note that any file paths must be fully qualified!

REM Example: elevate myAdminCommand -myArg1 -myArg2 someValue

if "%1"=="" (
    REM If no command is passed, simply open an elevated PowerShell window.
    PowerShell -Command "& {Start-Process PowerShell.exe -Wait -Verb RunAs}"
) ELSE (
    REM Copy command+arguments (passed as a parameter) into a ps1 file
    REM Start PowerShell with Elevated access (prompting UAC confirmation)
    REM     and run the ps1 file
    REM     then close elevated window when finished
    REM Output captured results

    IF EXIST %temp%\trans.txt del %temp%\trans.txt
    Echo %* ^> %temp%\trans.txt *^>^&1 > %temp%\tmp.ps1
    Echo $error[0] ^| Add-Content %temp%\trans.txt -Encoding Default >> %temp%\tmp.ps1
    PowerShell -Command "& {Start-Process PowerShell.exe -Wait -ArgumentList '-ExecutionPolicy Bypass -File ""%temp%\tmp.ps1""' -Verb RunAs}"
    Type %temp%\trans.txt
)

The accepted answer is comprehensive but related to the question i just want to put an simple example here. I had a code that i'd written it a long time ago. i wanted to traverse a tree with in-order way (left-node then root-node then right-node) and whenever i reach to one Node i wanted to be able to call a arbitrary function so that it could do everything.

void inorder_traversal(Node *p, void *out, void (*callback)(Node *in, void *out))
{
    if (p == NULL)
        return;
    inorder_traversal(p->left, out, callback);
    callback(p, out); // call callback function like this.
    inorder_traversal(p->right, out, callback);
}


// Function like bellow can be used in callback of inorder_traversal.
void foo(Node *t, void *out = NULL)
{
    // You can just leave the out variable and working with specific node of tree. like bellow.
    // cout << t->item;
    // Or
    // You can assign value to out variable like below
    // Mention that the type of out is void * so that you must firstly cast it to your proper out.
    *((int *)out) += 1;
}
// This function use inorder_travesal function to count the number of nodes existing in the tree.
void number_nodes(Node *t)
{
    int sum = 0;
    inorder_traversal(t, &sum, foo);
    cout << sum;
}

 int main()
{

    Node *root = NULL;
    // What These functions perform is inserting an integer into a Tree data-structure.
    root = insert_tree(root, 6);
    root = insert_tree(root, 3);
    root = insert_tree(root, 8);
    root = insert_tree(root, 7);
    root = insert_tree(root, 9);
    root = insert_tree(root, 10);
    number_nodes(root);
}

For some, this could be as easy as setting the system path for dynamic libraries. On OS X, this is as simple as setting the DYLD_LIBRARY_PATH environment variable. See:

Is it OK to use DYLD_LIBRARY_PATH on Mac OS X? And, what's the dynamic library search algorithm with it?

Using & is fine for short commands, but that single line can get very long very quick. When that happens, switch to multi-line syntax.

FOR /r %%X IN (*.txt) DO (
    ECHO %%X
    DEL %%X
)

Placement of ( and ) matters. The round brackets after DO must be placed on the same line, otherwise the batch file will be incorrect.

See if /?|find /V "" for details.

//do this on the css
div label input { margin-right:100px; }

A Popen object has a .wait() method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).

If you use this method, you'll prevent that the process zombies are lying around for too long.

(Alternatively, you can use subprocess.call() or subprocess.check_call() for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_)call().)

If you have several subprocesses to wait for, you can do

exit_codes = [p.wait() for p in p1, p2]

which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.

function Vcount() {
var modify = document.getElementById("C_name1").value;
var oTable = document.getElementById('dataTable');
var i;
var rowLength = oTable.rows.length;
for (i = 1; i < rowLength; i++) {
    var oCells = oTable.rows.item(i).cells;
    if (modify == oCells[0].firstChild.data) {
        document.getElementById("Error").innerHTML = "  * duplicate value";
        return false;
        break;
    }

}

Try this:

array.inject(0){|sum,x| sum + x }

See Ruby's Enumerable Documentation

(note: the 0 base case is needed so that 0 will be returned on an empty array instead of nil)

We made the decision to store as varbinary for http://www.freshlogicstudios.com/Products/Folders/ halfway expecting performance issues. I can say that we've been pleasantly surprised at how well it's worked out.

I have tried this with and without the WRITE_INTERNAL_STORAGE permission.

There is no WRITE_INTERNAL_STORAGE permission in Android.

How do I create this file for writing?

You don't, except perhaps on a rooted device, if your app is running with superuser privileges. You are trying to write to the root of internal storage, which apps do not have access to.

Please use the version of the FileOutputStream constructor that takes a File object. Create that File object based off of some location that you can write to, such as:

• getFilesDir() (called on your Activity or other Context)
• getExternalFilesDir() (called on your Activity or other Context)

The latter will require WRITE_EXTERNAL_STORAGE as a permission.

Is there an easier way than writing it to a file then reading from it again?

You can temporarily put it in a static data member.

because many people don't have SD card slots

"SD card slots" are irrelevant, by and large. 99% of Android device users will have external storage -- the exception will be 4+ year old devices where the user removed their SD card. Devices manufactured since mid-2010 have external storage as part of on-board flash, not as removable media.

Sometimes all it takes to get a EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) is a missing return statement.

It certainly was my case.

Use Instant to compute microseconds since Epoch:

val instant = Instant.now();
val currentTimeMicros = instant.getEpochSecond() * 1000_000 + instant.getNano() / 1000;

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".

The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button

There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.

If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.

Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.

@BrenBarn's answer says it all, but if you're like me it might take a while to understand. Here's my case and how @BrenBarn's answer applies to it, perhaps it will help you.

The case

package/
    __init__.py
    subpackage1/
        __init__.py
        moduleX.py
    moduleA.py

Using our familiar example, and add to it that moduleX.py has a relative import to ..moduleA. Given that I tried writing a test script in the subpackage1 directory that imported moduleX, but then got the dreaded error described by the OP.

Solution

Move test script to the same level as package and import package.subpackage1.moduleX

Explanation

As explained, relative imports are made relative to the current name. When my test script imports moduleX from the same directory, then module name inside moduleX is moduleX. When it encounters a relative import the interpreter can't back up the package hierarchy because it's already at the top

When I import moduleX from above, then name inside moduleX is package.subpackage1.moduleX and the relative import can be found

If you have another file in same directory, you can either do:

bash another_script.sh

or

source another_script.sh

or

. another_script.sh

When you use bash instead of source, the script cannot alter environment of the parent script. The . command is POSIX standard while source command is a more readable bash synonym for . (I prefer source over .). If your script resides elsewhere just provide path to that script. Both relative as well as full path should work.

You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.

Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/

The minimum requirements are based on the Express edition you're attempting to install:

Express for Web (Web sites and HTML5 applications) - Windows 7 SP1 (With IE 10)
Express for Windows (Windows 8 Apps) - Windows 8.1
Express for Windows Desktop (Windows Programs) - Windows 7 SP1 (With IE 10)
Express for Windows Phone (Windows Phone Apps) - Windows 8

It sounds like you're trying to install the "Express 2013 for Windows" edition, which is for developing Windows 8 "Modern UI" apps, or the Windows Phone edition.

The similarly named version that is compatible with Windows 7 SP1 is "Express 2013 for Windows Desktop"

Source

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

You can include HTML content. One possibility is encoding it in BASE64 as you have mentioned.

Another might be using CDATA tags.

Example using CDATA:

<xml>
    <title>Your HTML title</title>
    <htmlData><![CDATA[<html>
        <head>
            <script/>
        </head>
        <body>
        Your HTML's body
        </body>
        </html>
     ]]>
    </htmlData>
</xml>

Please note:

CDATA's opening character sequence: <![CDATA[

CDATA's closing character sequence: ]]>

You will have to provide a link to your file that is accessible through the browser, that is for instance:

<a href="http://my.domain.com/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

versus

<a href="C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

If you expose your "Projecten" folder directly to the public, then you may only have to provide the link as such:

<a href="/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

But beware, that your files can then be indexed by search engines, can be accessed by anybody having this link, etc.

You can validate group checkbox and radio button without extra js code, see below example.

Your JS should be look like:

$("#formid").validate();

You can play with HTML tag and attributes: eg. group checkbox [minlength=2 and maxlength=4]

<fieldset class="col-md-12">
  <legend>Days</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="1" required="required" data-msg-required="This value is required." minlength="2" maxlength="4" data-msg-maxlength="Max should be 4">Monday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="2">Tuesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="3">Wednesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="4">Thursday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="5">Friday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="6">Saturday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="7">Sunday
        </label>
        <label for="daysgroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

You can see here first or any one input should have required, minlength="2" and maxlength="4" attributes. minlength/maxlength as per your requirement.

eg. group radio button:

<fieldset class="col-md-12">
  <legend>Gender</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="m" required="required" data-msg-required="This value is required.">man
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="w">woman
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="o">other
        </label>
        <label for="gendergroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

You can check working example here.

• jQuery v3.3.x
• jQuery Validation Plugin - v1.17.0

You can use this method:

boolean isAlive()

It returns true if the thread is still alive and false if the Thread is dead. This is not static. You need a reference to the object of the Thread class.

One more tip: If you're checking it's status to make the main thread wait while the new thread is still running, you may use join() method. It is more handy.

Runtime.getRuntime().exec(cls) did NOT work on my XP laptop. This did -

for(int clear = 0; clear < 1000; clear++)
  {
     System.out.println("\b") ;
  }

Hope this is useful

Here an example with 100000 rows (occupations are set here from A to Z):

> a = data.frame(sex=sample(c("M", "F"), 100000, replace=T), occupation=sample(LETTERS, 100000, replace=T))
> sum(a$sex == "M" & a$occupation=="A")
[1] 1882

returns the number of males with occupation "A".

EDIT

As I understand from your comment, you want the counts of all possible combinations of sex and occupation. So first create a dataframe with all combinations:

combns = expand.grid(c("M", "F"), LETTERS)

and loop with apply to sum for your criteria and append the results to combns:

combns = cbind (combns, apply(combns, 1, function(x)sum(a$sex==x[1] & a$occupation==x[2])))
colnames(combns) = c("sex", "occupation", "count")

The first rows of your result look as follows:

  sex occupation count
1   M          A  1882
2   F          A  1869
3   M          B  1866
4   F          B  1904
5   M          C  1979
6   F          C  1910

Does this solve your problem?

OR:

Much easier solution suggested by thelatemai:

table(a$sex, a$occupation)


       A    B    C    D    E    F    G    H    I    J    K    L    M    N    O
  F 1869 1904 1910 1907 1894 1940 1964 1907 1918 1892 1962 1933 1886 1960 1972
  M 1882 1866 1979 1904 1895 1845 1946 1905 1999 1994 1933 1950 1876 1856 1911

       P    Q    R    S    T    U    V    W    X    Y    Z
  F 1908 1907 1883 1888 1943 1922 2016 1962 1885 1898 1889
  M 1928 1938 1916 1927 1972 1965 1946 1903 1965 1974 1906

This can also be caused if you include bootstrap.js before jquery.js.

Others might have the same problem I did.

Include jQuery before bootstrap.

If you run the following in SQL Server, you'll notice that COUNT(1) is evaluated as COUNT(*) anyway. So it appears that there is no difference, and also that COUNT(*) is the expression most native to the query optimizer:

SET SHOWPLAN_TEXT ON
GO

SELECT COUNT(1)
FROM <table>
GO

SET SHOWPLAN_TEXT OFF
GO

To view your iOS device's console in Safari on your Mac (Mac only apparently):

1. On your iOS device, go to Settings > Safari > Advanced and switch on Web Inspector
2. On your iOS device, load your web page in Safari
3. Connect your device directly to your Mac
4. On your Mac, if you've not already got Safari's Developer menu activated, go to Preferences > Advanced, and select "Show Develop menu in menu bar"
5. On your Mac, go to Develop > [your iOS device name] > [your web page]

Safari's Inspector will appear showing a console for your iOS device.

You should use Array.reduce for this.

var options = [_x000D_
  { name: 'One', assigned: true }, _x000D_
  { name: 'Two', assigned: false }, _x000D_
  { name: 'Three', assigned: true }, _x000D_
];_x000D_
_x000D_
var reduced = options.reduce(function(filtered, option) {_x000D_
  if (option.assigned) {_x000D_
     var someNewValue = { name: option.name, newProperty: 'Foo' }_x000D_
     filtered.push(someNewValue);_x000D_
  }_x000D_
  return filtered;_x000D_
}, []);_x000D_
_x000D_
document.getElementById('output').innerHTML = JSON.stringify(reduced);

<h1>Only assigned options</h1>_x000D_
<pre id="output"> </pre>

Alternatively, the reducer can be a pure function, like this

var reduced = options.reduce(function(result, option) {
  if (option.assigned) {
    return result.concat({
      name: option.name,
      newProperty: 'Foo'
    });
  }
  return result;
}, []);

Well, the "text-overflow: ellipsis" worked for me, but just if my limit was based on 'width', I has needed a solution that can be applied on lines ( on the'height' instead the 'width' ) so I did this script:

function listLimit (elm, line){
    var maxHeight = parseInt(elm.css('line-Height'))*line;

    while(elm.height() > maxHeight){
        var text = elm.text();
        elm.text(text.substring(0,text.length-10)).text(elm.text()+'...');
    }
}

And when I must, for example, that my h3 has only 2 lines I do :

$('h3').each(function(){
   listLimit ($(this), 2)
})

I dunno if that was the best practice for performance needs, but worked for me.

Cohesion refers to what the class (or module) can do. Low cohesion would mean that the class does a great variety of actions - it is broad, unfocused on what it should do. High cohesion means that the class is focused on what it should be doing, i.e. only methods relating to the intention of the class.

Example of Low Cohesion:

-------------------
| Staff           |
-------------------
| checkEmail()    |
| sendEmail()     |
| emailValidate() |
| PrintLetter()   |
-------------------

Example of High Cohesion:

----------------------------
| Staff                   |
----------------------------
| -salary                 |
| -emailAddr              |
----------------------------
| setSalary(newSalary)    |
| getSalary()             |
| setEmailAddr(newEmail)  |
| getEmailAddr()          |
----------------------------

As for coupling, it refers to how related or dependent two classes/modules are toward each other. For low coupled classes, changing something major in one class should not affect the other. High coupling would make it difficult to change and maintain your code; since classes are closely knit together, making a change could require an entire system revamp.

Good software design has high cohesion and low coupling.

TextView comes with 4 compound drawables, one for each of left, top, right and bottom.

In your case, you do not need the LinearLayout and ImageView at all. Just add android:drawableLeft="@drawable/up_count_big" to your TextView.

See TextView#setCompoundDrawablesWithIntrinsicBounds for more info.

Interfaces are generally the classes without logic just a signature. Whereas abstract classes are those having logic. Both support contract as interface all method should be implemented in the child class but in abstract only the abstract method should be implemented. When to use interface and when to abstract? Why use Interface?

class Circle {

protected $radius;

public function __construct($radius)

{
    $this->radius = $radius
}

public function area()
{
    return 3.14159 * pow(2,$this->radius); // simply pie.r2 (square);
}

}

//Our area calculator class would look like

class Areacalculator {

$protected $circle;

public function __construct(Circle $circle)
{
    $this->circle = $circle;
}

public function areaCalculate()
{
    return $circle->area(); //returns the circle area now
}

}

We would simply do

$areacalculator = new Areacalculator(new Circle(7)); 

Few days later we would need the area of rectangle, Square, Quadrilateral and so on. If so do we have to change the code every time and check if the instance is of square or circle or rectangle? Now what OCP says is CODE TO AN INTERFACE NOT AN IMPLEMENTATION. Solution would be:

Interface Shape {

public function area(); //Defining contract for the classes

}

Class Square implements Shape {

$protected length;

public function __construct($length) {
    //settter for length like we did on circle class
}

public function area()
{
    //return l square for area of square
}

Class Rectangle implements Shape {

$protected length;
$protected breath;

public function __construct($length,$breath) {
    //settter for length, breath like we did on circle,square class
}

public function area()
{
    //return l*b for area of rectangle
}

}

Now for area calculator

class Areacalculator {

$protected $shape;

public function __construct(Shape $shape)
{
    $this->shape = $shape;
}

public function areaCalculate()
{
    return $shape->area(); //returns the circle area now
}

}

$areacalculator = new Areacalculator(new Square(1));
$areacalculator->areaCalculate();

$areacalculator = new Areacalculator(new Rectangle(1,2));
$areacalculator->;areaCalculate();

Isn't that more flexible? If we would code without interface we would check the instance for each shape redundant code.

Now when to use abstract?

Abstract Animal {

public function breathe(){

//all animals breathe inhaling o2 and exhaling co2

}

public function hungry() {

//every animals do feel hungry 

}

abstract function communicate(); 
// different communication style some bark, some meow, human talks etc

}

Now abstract should be used when one doesn't need instance of that class, having similar logic, having need for the contract.

I had the same issue.

Make sure that In SQL Server configuration --> SQL Server Services --> SQL Server Agent is enable

This solved my problem

Create a list of lists:

with open("/path/to/file") as file:
    lines = []
    for line in file:
        # The rstrip method gets rid of the "\n" at the end of each line
        lines.append(line.rstrip().split(","))

At least in Firefox (v3.5), cache seems to be disabled rather than simply cleared. If there are multiple instances of the same image on a page, it will be transferred multiple times. That is also the case for img tags that are added subsequently via Ajax/JavaScript.

So in case you're wondering why the browser keeps downloading the same little icon a few hundred times on your auto-refresh Ajax site, it's because you initially loaded the page using CTRL-F5.

The real issue is that with vanilla Android Studio v 0.8 beta, it only installs/recognize SDK 20 which is android L. In order to target another complieSDK you need to install it via the SDK manager. Once it is set, you can then change the compileSDK to a lower version and it should work.

you may also want to restrict the compatibility library, it needs to be restricted from using the latest version of the library so change the dependecy to something like :

compile('com.android.support:appcompat-v7:19.1.0') {
    // really use 19.1.0 even if something else resolves higher
    force = true
}

First, there is no such thing as a JSON object. JSON is a string format that can be used as a representation of a Javascript object literal.

Since JSON is a string, Javascript will treat it like a string, and not like an object (or array or whatever you are trying to use it as.)

Here is a good JSON reference to clarify this difference:

http://benalman.com/news/2010/03/theres-no-such-thing-as-a-json/

So if you need accomplish the task mentioned in your question, you must convert the JSON string to an object or deal with it as a string, and not as a JSON array. There are several libraries to accomplish this. Look at http://www.json.org/js.html for a reference.

I use this code. It makes sure that file gets created if it doesn't exist and also adds bit of error checks.

static void appendLineToFile(string filepath, string line)
{
    std::ofstream file;
    //can't enable exception now because of gcc bug that raises ios_base::failure with useless message
    //file.exceptions(file.exceptions() | std::ios::failbit);
    file.open(filepath, std::ios::out | std::ios::app);
    if (file.fail())
        throw std::ios_base::failure(std::strerror(errno));

    //make sure write fails with exception if something is wrong
    file.exceptions(file.exceptions() | std::ios::failbit | std::ifstream::badbit);

    file << line << std::endl;
}

You can get the names from the schema by doing

spark_df.schema.names

Printing the schema can be useful to visualize it as well

spark_df.printSchema()

simple in python 3.6

o = open('outfile','w')

print('hello world', file=o)

o.close()

I was looking for something like I did in Perl

my $printname = "outfile"

open($ph, '>', $printname)
    or die "Could not open file '$printname' $!";

print $ph "hello world\n";

One common way is to add the image to a QLabel widget using QLabel::setPixmap(), and then display the QLabel as you would any other widget. Example:

#include <QtGui>

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  QPixmap pm("your-image.jpg");
  QLabel lbl;
  lbl.setPixmap(pm);
  lbl.show();
  return app.exec();
}

You can use ScrimInsetFrameLayout

https://github.com/google/iosched/blob/master/android/src/main/java/com/google/samples/apps/iosched/ui/widget/ScrimInsetsFrameLayout.java

android:fitsSystemWindows="true" should set on scrim layout!

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

Cleaning up Isaac's answer:

});

EDIT

ES6 helper function:

function addMultipleEventListener(element, events, handler) {
  events.forEach(e => element.addEventListener(e, handler))
}

Testing for name pointing to None and name existing are two semantically different operations.

To check if val is None:

if val is None:
    pass  # val exists and is None

To check if name exists:

try:
    val
except NameError:
    pass  # val does not exist at all

Whatever is assigned to the files variable is incorrect. Use the following code.

import glob
import os

list_of_files = glob.glob('/path/to/folder/*') # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getctime)
print(latest_file)

To get the current path from within the JSP file you can simply do one of the following:

<%= request.getContextPath() %>
<%= request.getRequestURI() %>
<%= request.getRequestURL() %>

Popen.communicate() documentation:

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Replacing os.popen*

    pipe = os.popen(cmd, 'w', bufsize)
    # ==>
    pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin

Warning Use communicate() rather than stdin.write(), stdout.read() or stderr.read() to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

So your example could be written as follows:

from subprocess import Popen, PIPE, STDOUT

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=STDOUT)    
grep_stdout = p.communicate(input=b'one\ntwo\nthree\nfour\nfive\nsix\n')[0]
print(grep_stdout.decode())
# -> four
# -> five
# ->

On Python 3.5+ (3.6+ for encoding), you could use subprocess.run, to pass input as a string to an external command and get its exit status, and its output as a string back in one call:

#!/usr/bin/env python3
from subprocess import run, PIPE

p = run(['grep', 'f'], stdout=PIPE,
        input='one\ntwo\nthree\nfour\nfive\nsix\n', encoding='ascii')
print(p.returncode)
# -> 0
print(p.stdout)
# -> four
# -> five
# -> 

It is now possible to create a pandas column containing NaNs as dtype int, since it is now officially added on pandas 0.24.0

pandas 0.24.x release notes Quote: "Pandas has gained the ability to hold integer dtypes with missing values

I think the answers are below

List<string> aa = (from char c in source
                    select c.ToString() ).ToList();

List<string> aa2 = (from char c1 in source
                    from char c2 in source
                    select string.Concat(c1, ".", c2)).ToList();

SGML parsers (or XML parsers in the case of XHTML) can handle — without having to process the DTD (which doesn't matter to browsers as they just slurp tag soup), while — is easier for humans to read and write in the source code.

Personally, I would stick to a literal em-dash and ensure that my character encoding settings were consistent.

On my system: CentOS 5

I can use \s outside of collections but have to use [:space:] inside of collections. In fact I can use [:space:] only inside collections. So to match a single space using this I have to use [[:space:]] Which is really strange.

echo a b cX | sed -r "s/(a\sb[[:space:]]c[^[:space:]])/Result: \1/"

Result: a b cX

• first space I match with \s
• second space I match alternatively with [[:space:]]
• the X I match with "all but no space" [^[:space:]]

These two will not work:

a[:space:]b  instead use a\sb or a[[:space:]]b

a[^\s]b      instead use a[^[:space:]]b

Yes, it is possible. All you have to do is change your query to something like SELECT i.foo, i.bar FROM ObjectName i WHERE i.id = 10. The result of the query will be a List of array of Object. The first element in each array is the value of i.foo and the second element is the value i.bar. See the relevant section of JPQL reference.

You can use inline styling to limit the height:

<img src="" class="img-responsive" alt="" style="max-height: 400px;">

Here is a Swift version of the accepted answer:

Swift 3:

let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
                                        for: .normal)

Swift 2.2:

let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font], 
    forState: UIControlState.Normal)

1. Install Java 7u21 from: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u21-oth-JPR

2. Set these variables:

   export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home
   export PATH=$JAVA_HOME/bin:$PATH
   

3. Run your app and have fun :)

For swift 2.0:

let cacheSizeMemory = 4*1024*1024; // 4MB
let cacheSizeDisk = 32*1024*1024; // 32MB
let sharedCache = NSURLCache(memoryCapacity: cacheSizeMemory, diskCapacity: cacheSizeDisk, diskPath: "nsurlcache")
NSURLCache.setSharedURLCache(sharedCache)

I surprise no one had mentioned this possible easy approach in visual studio code.

Install VS Code and Apache maven ( just as mentioned by @Steve Chambers)

After installing this extension vscode:extension/vscjava.vscode-java-pack

In the java overview page , there is a an option which reads 'Create Maven Project' which further takes to a simple wizard to generate maven project.

Its pretty quick which is intutitive enough, even newbies can very well start with a Maven project.

or you can use

$('#myDiv').toggle("slide:right");

Yet another way

git status -b --porcelain

This will give you

## BRANCH(...REMOTE)
modified and untracked files

You can use the following line:

head -n 10 /path/to/file | grep [...]

In addition to all the other correct answers, since Rails.root is a Pathname object, this won't work:

Rails.root + '/app/assets/...'

You could use something like join

Rails.root.join('app', 'assets')

If you want a string use this:

Rails.root.join('app', 'assets').to_s

Dicts can't be sorted, but you can build a sorted list from them.

A sorted list of dict values:

sorted(d.values())

A list of (key, value) pairs, sorted by value:

from operator import itemgetter
sorted(d.items(), key=itemgetter(1))

Just @OneToMany(cascade = CascadeType.ALL, mappedBy = "xxx", fetch = FetchType.LAZY, orphanRemoval = true).

Remove targetEntity = MyClass.class, it works great.

I was able to call stored procedure in a view (SQL Server 2005).

CREATE FUNCTION [dbo].[dimMeasure] 
   RETURNS  TABLE  AS

    (
     SELECT * FROM OPENROWSET('SQLNCLI', 'Server=localhost; Trusted_Connection=yes;', 'exec ceaw.dbo.sp_dimMeasure2')
    )
RETURN
GO

Inside stored procedure we need to set:

set nocount on
SET FMTONLY OFF

CREATE VIEW [dbo].[dimMeasure]
AS

SELECT * FROM OPENROWSET('SQLNCLI', 'Server=localhost;Trusted_Connection=yes;', 'exec ceaw.dbo.sp_dimMeasure2')

GO

Your code works fine.

def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]

for (objKey in tmpHM.keySet()) {   
    HashMap objHM = (HashMap) list.get(objKey);
    print("objHM: ${objHM}  , ")
}

prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

Then click "edit in console", "execute script"

I have a similar problem (at least I think it is similar). In one of the replies here the solution is as follows:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

That WHERE clause I would like to be:

WHERE B.tag = A.<col_name>

or, in my specific case:

WHERE B.val BETWEEN A.val1 AND A.val2

More detailed:

Table A carries status information of a fleet of equipment. Each status record carries with it a start and stop time of that status. Table B carries regularly recorded, timestamped data about the equipment, which I want to extract for the duration of the period indicated in table A.

Add a method to the enum like:

public String getString() {
    return this.name();
}

For example

public enum MyEnum {
    VALUE_1,
    VALUE_2;
    public String getString() {
        return this.name();
    }
}

Then you can use:

<c:if test="${myObject.myEnumProperty.string eq 'VALUE_2'}">...</c:if>

If you know it's going to be just two fields, you can skip the extra subprocesses like this:

var1=${STR%-*}
var2=${STR#*-}

What does this do? ${STR%-*} deletes the shortest substring of $STR that matches the pattern -* starting from the end of the string. ${STR#*-} does the same, but with the *- pattern and starting from the beginning of the string. They each have counterparts %% and ## which find the longest anchored pattern match. If anyone has a helpful mnemonic to remember which does which, let me know! I always have to try both to remember.

See itertools.combinations or itertools.permutations.
