I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

**To avoid XSS security threat in spring application**

solution to the XSS issue is to filter all the textfields in the form at the time of submitting the form.

    It needs XML entry in the web.xml file & two simple classes.

        java code :-
        The code for the  first class named CrossScriptingFilter.java is :

        package com.filter;

        import java.io.IOException;
        import javax.servlet.Filter;
        import javax.servlet.FilterChain;
        import javax.servlet.FilterConfig;
        import javax.servlet.ServletException;
        import javax.servlet.ServletRequest;
        import javax.servlet.ServletResponse;
        import javax.servlet.http.HttpServletRequest;
        import org.apache.log4j.Logger;

        public class CrossScriptingFilter implements Filter {
            private static Logger logger = Logger.getLogger(CrossScriptingFilter.class);
            private FilterConfig filterConfig;

            public void init(FilterConfig filterConfig) throws ServletException {
                this.filterConfig = filterConfig;
            }

            public void destroy() {
                this.filterConfig = null;
            }

            public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
                logger.info("Inlter CrossScriptingFilter  ...............");
                chain.doFilter(new RequestWrapper((HttpServletRequest) request), response);
                logger.info("Outlter CrossScriptingFilter ...............");
            }

        }

The code second class named RequestWrapper.java is :

package com.filter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

import org.apache.log4j.Logger;

public final class RequestWrapper extends HttpServletRequestWrapper {
    private static Logger logger = Logger.getLogger(RequestWrapper.class);
    public RequestWrapper(HttpServletRequest servletRequest) {
        super(servletRequest);
    }

    public String[] getParameterValues(String parameter) {
        logger.info("InarameterValues .. parameter .......");
        String[] values = super.getParameterValues(parameter);
        if (values == null) {
            return null;
        }
        int count = values.length;
        String[] encodedValues = new String[count];
        for (int i = 0; i < count; i++) {
            encodedValues[i] = cleanXSS(values[i]);
        }
        return encodedValues;
    }

    public String getParameter(String parameter) {
        logger.info("Inarameter .. parameter .......");
        String value = super.getParameter(parameter);
        if (value == null) {
            return null;
        }
        logger.info("Inarameter RequestWrapper ........ value .......");
        return cleanXSS(value);
    }

    public String getHeader(String name) {
        logger.info("Ineader .. parameter .......");
        String value = super.getHeader(name);
        if (value == null)
            return null;
        logger.info("Ineader RequestWrapper ........... value ....");
        return cleanXSS(value);
    }

    private String cleanXSS(String value) {
        // You'll need to remove the spaces from the html entities below
        logger.info("InnXSS RequestWrapper ..............." + value);
        //value = value.replaceAll("<", "& lt;").replaceAll(">", "& gt;");
        //value = value.replaceAll("\\(", "& #40;").replaceAll("\\)", "& #41;");
        //value = value.replaceAll("'", "& #39;");
        value = value.replaceAll("eval\\((.*)\\)", "");
        value = value.replaceAll("[\\\"\\\'][\\s]*javascript:(.*)[\\\"\\\']", "\"\"");

        value = value.replaceAll("(?i)<script.*?>.*?<script.*?>", "");
        value = value.replaceAll("(?i)<script.*?>.*?</script.*?>", "");
        value = value.replaceAll("(?i)<.*?javascript:.*?>.*?</.*?>", "");
        value = value.replaceAll("(?i)<.*?\\s+on.*?>.*?</.*?>", "");
        //value = value.replaceAll("<script>", "");
        //value = value.replaceAll("</script>", "");
        logger.info("OutnXSS RequestWrapper ........ value ......." + value);
        return value;
    }

The only thing remained is the XML entry in the web.xml file:

        <filter>
        <filter-name>XSS</filter-name>
        <display-name>XSS</display-name>
        <description></description>
        <filter-class>com.filter.CrossScriptingFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>XSS</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

The /* indicates that for every request made from browser, it will call CrossScriptingFilter class. Which will parse all the components/elements came from the request & will replace all the javascript tags put by hacker with empty string i.e

The correct syntax is mysql> SET @@global.group_concat_max_len = integer;
If you do not have the privileges to do this on the server where your database resides then use a query like:
mySQL="SET @@session.group_concat_max_len = 10000;"or a different value.
Next line:
SET objRS = objConn.Execute(mySQL)  your variables may be different.
then
mySQL="SELECT GROUP_CONCAT(......);" etc
I use the last version since I do not have the privileges to change the default value of 1024 globally (using cPanel).
Hope this helps.

you can use instead of click :

$('#whatever').on('touchstart click', function(){ /* do something... */ });

I found that I needed to wrap my datetime string like this:

"startdate": "\/Date(" + date() + ")\/"

Took me an hour to figure out how to enable the WCF service to give me back the error message which told me that XD

You will need to use strip() because of the extra bits in the strings.

A2 = [float(x.strip('"')) for x in A1]

Is it actually faster to use say (i<<3)+(i<<1) to multiply with 10 than using i*10 directly?

It might or might not be on your machine - if you care, measure in your real-world usage.

A case study - from 486 to core i7

Benchmarking is very difficult to do meaningfully, but we can look at a few facts. From http://www.penguin.cz/~literakl/intel/s.html#SAL and http://www.penguin.cz/~literakl/intel/i.html#IMUL we get an idea of x86 clock cycles needed for arithmetic shift and multiplication. Say we stick to "486" (the newest one listed), 32 bit registers and immediates, IMUL takes 13-42 cycles and IDIV 44. Each SAL takes 2, and adding 1, so even with a few of those together shifting superficially looks like a winner.

These days, with the core i7:

(from http://software.intel.com/en-us/forums/showthread.php?t=61481)

The latency is 1 cycle for an integer addition and 3 cycles for an integer multiplication. You can find the latencies and thoughput in Appendix C of the "Intel® 64 and IA-32 Architectures Optimization Reference Manual", which is located on http://www.intel.com/products/processor/manuals/.

(from some Intel blurb)

Using SSE, the Core i7 can issue simultaneous add and multiply instructions, resulting in a peak rate of 8 floating-point operations (FLOP) per clock cycle

That gives you an idea of how far things have come. The optimisation trivia - like bit shifting versus * - that was been taken seriously even into the 90s is just obsolete now. Bit-shifting is still faster, but for non-power-of-two mul/div by the time you do all your shifts and add the results it's slower again. Then, more instructions means more cache faults, more potential issues in pipelining, more use of temporary registers may mean more saving and restoring of register content from the stack... it quickly gets too complicated to quantify all the impacts definitively but they're predominantly negative.

functionality in source code vs implementation

More generally, your question is tagged C and C++. As 3rd generation languages, they're specifically designed to hide the details of the underlying CPU instruction set. To satisfy their language Standards, they must support multiplication and shifting operations (and many others) even if the underlying hardware doesn't. In such cases, they must synthesize the required result using many other instructions. Similarly, they must provide software support for floating point operations if the CPU lacks it and there's no FPU. Modern CPUs all support * and <<, so this might seem absurdly theoretical and historical, but the significance thing is that the freedom to choose implementation goes both ways: even if the CPU has an instruction that implements the operation requested in the source code in the general case, the compiler's free to choose something else that it prefers because it's better for the specific case the compiler's faced with.

Examples (with a hypothetical assembly language)

source           literal approach         optimised approach
#define N 0
int x;           .word x                xor registerA, registerA
x *= N;          move x -> registerA
                 move x -> registerB
                 A = B * immediate(0)
                 store registerA -> x
  ...............do something more with x...............

Instructions like exclusive or (xor) have no relationship to the source code, but xor-ing anything with itself clears all the bits, so it can be used to set something to 0. Source code that implies memory addresses may not entail any being used.

These kind of hacks have been used for as long as computers have been around. In the early days of 3GLs, to secure developer uptake the compiler output had to satisfy the existing hardcore hand-optimising assembly-language dev. community that the produced code wasn't slower, more verbose or otherwise worse. Compilers quickly adopted lots of great optimisations - they became a better centralised store of it than any individual assembly language programmer could possibly be, though there's always the chance that they miss a specific optimisation that happens to be crucial in a specific case - humans can sometimes nut it out and grope for something better while compilers just do as they've been told until someone feeds that experience back into them.

So, even if shifting and adding is still faster on some particular hardware, then the compiler writer's likely to have worked out exactly when it's both safe and beneficial.

Maintainability

If your hardware changes you can recompile and it'll look at the target CPU and make another best choice, whereas you're unlikely to ever want to revisit your "optimisations" or list which compilation environments should use multiplication and which should shift. Think of all the non-power-of-two bit-shifted "optimisations" written 10+ years ago that are now slowing down the code they're in as it runs on modern processors...!

Thankfully, good compilers like GCC can typically replace a series of bitshifts and arithmetic with a direct multiplication when any optimisation is enabled (i.e. ...main(...) { return (argc << 4) + (argc << 2) + argc; } -> imull $21, 8(%ebp), %eax) so a recompilation may help even without fixing the code, but that's not guaranteed.

Strange bitshifting code implementing multiplication or division is far less expressive of what you were conceptually trying to achieve, so other developers will be confused by that, and a confused programmer's more likely to introduce bugs or remove something essential in an effort to restore seeming sanity. If you only do non-obvious things when they're really tangibly beneficial, and then document them well (but don't document other stuff that's intuitive anyway), everyone will be happier.

General solutions versus partial solutions

If you have some extra knowledge, such as that your int will really only be storing values x, y and z, then you may be able to work out some instructions that work for those values and get you your result more quickly than when the compiler's doesn't have that insight and needs an implementation that works for all int values. For example, consider your question:

Multiplication and division can be achieved using bit operators...

You illustrate multiplication, but how about division?

int x;
x >> 1;   // divide by 2?

According to the C++ Standard 5.8:

-3- The value of E1 >> E2 is E1 right-shifted E2 bit positions. If E1 has an unsigned type or if E1 has a signed type and a nonnegative value, the value of the result is the integral part of the quotient of E1 divided by the quantity 2 raised to the power E2. If E1 has a signed type and a negative value, the resulting value is implementation-defined.

So, your bit shift has an implementation defined result when x is negative: it may not work the same way on different machines. But, / works far more predictably. (It may not be perfectly consistent either, as different machines may have different representations of negative numbers, and hence different ranges even when there are the same number of bits making up the representation.)

You may say "I don't care... that int is storing the age of the employee, it can never be negative". If you have that kind of special insight, then yes - your >> safe optimisation might be passed over by the compiler unless you explicitly do it in your code. But, it's risky and rarely useful as much of the time you won't have this kind of insight, and other programmers working on the same code won't know that you've bet the house on some unusual expectations of the data you'll be handling... what seems a totally safe change to them might backfire because of your "optimisation".

Is there any sort of input that can't be multiplied or divided in this way?

Yes... as mentioned above, negative numbers have implementation defined behaviour when "divided" by bit-shifting.

Here is a pitfall to avoid. In case you need to access your variable $name within a function, you need to say "global $name;" at the beginning of that function. You need to repeat this for each function in the same file.

include('front.inc');
global $name;

function foo() {
  echo $name;
}

function bar() {
  echo $name;
}

foo();
bar();

will only show errors. The correct way to do that would be:

include('front.inc');

function foo() {
  global $name;
  echo $name;
}

function bar() {
  global $name;
  echo $name;
}

foo();
bar();

I had to use the install function instead:

conda install pandas=0.13.1

A type variable, <T>, can be any non-primitive type you specify: any class type, any interface type, any array type, or even another type variable.

The most commonly used type parameter names are:

• E - Element (used extensively by the Java Collections Framework)
• K - Key
  
• N - Number
  
• T - Type
  
• V - Value
  

In Java 7 it is permitted to instantiate like this:

Foo<String, Integer> foo = new Foo<>(); // Java 7
Foo<String, Integer> foo = new Foo<String, Integer>(); // Java 6

This is a solution to make the keyboard go away when hit return in any textfield, by adding code in one place (so don't have to add a handler for each textfield):

consider this scenario:

i have a viewcontroller with two textfields (username and password). and the viewcontroller implements UITextFieldDelegate protocol

i do this in viewDidLoad

- (void)viewDidLoad 
{
    [super viewDidLoad];

    username.delegate = self;
    password.delegate = self;
}

and the viewcontroller implements the optional method as

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

and irrespective of the textfield you are in, as soon as i hit return in the keyboard, it gets dismissed!

In your case, the same would work as long as you set all the textfield's delegate to self and implement textFieldShouldReturn

As a general rule, you can’t just set the color of a horizontal line with CSS like you would anything else. First of all, Internet Explorer needs the color in your CSS to read like this:

“color: #123455”

But Opera and Mozilla needs the color in your CSS to read like this:

“background-color: #123455”

So, you will need to add both options to your CSS.

Next, you will need to give the horizontal line some dimensions or it will default to the standard height, width and color set by your browser. Here is a sample code of what your CSS should look like to get the blue horizontal line.

hr {
border: 0;
width: 100%;
color: #123455;
background-color: #123455;
height: 5px;
}

Or you could just add the style to your HTML page directly when you insert a horizontal line, like this:

<hr style="background:#123455" />

Hope this helps.

If you really need to use sys.path.insert, consider leaving sys.path[0] as it is:

sys.path.insert(1, path_to_dev_pyworkbooks)

This could be important since 3rd party code may rely on sys.path documentation conformance:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter.

in controller:

JSONObject jsonobject=new JSONObject();
jsonobject.put("error","Invalid username");
response.getWriter().write(jsonobject.toString());

in javascript:

f(data!=success){



 var errorMessage=jQuery.parseJson(data);
  alert(errorMessage.error);
}

I tried the previous answer about pinch-to-zoom

document.documentElement.addEventListener('touchstart', function (event) {
    if (event.touches.length > 1) {
        event.preventDefault();
    }
}, false);

however sometime the screen still zoom when the event.touches.length > 1 I found out the best way is using touchmove event, to avoid any finger moving on the screen. The code will be something like this:

document.documentElement.addEventListener('touchmove', function (event) {
    event.preventDefault();      
}, false);

Hope it will help.

Other answers here discuss the various problems with trying to do this. I thought I'd show how you might try this in case you wanted to learn by doing it yourself.

You can connect to an mail server via telnet to ask whether an email address exists. Here's an example of testing an email address for stackoverflow.com:

C:\>nslookup -q=mx stackoverflow.com
Non-authoritative answer:
stackoverflow.com       MX preference = 40, mail exchanger = STACKOVERFLOW.COM.S9B2.PSMTP.com
stackoverflow.com       MX preference = 10, mail exchanger = STACKOVERFLOW.COM.S9A1.PSMTP.com
stackoverflow.com       MX preference = 20, mail exchanger = STACKOVERFLOW.COM.S9A2.PSMTP.com
stackoverflow.com       MX preference = 30, mail exchanger = STACKOVERFLOW.COM.S9B1.PSMTP.com

Lines prefixed with numeric codes are responses from the SMTP server. I added some blank lines to make it more readable.

Many mail servers will not return this information as a means to prevent against email address harvesting by spammers, so you cannot rely on this technique. However you may have some success at cleaning out some obviously bad email addresses by detecting invalid mail servers, or having recipient addresses rejected as above.

Note too that mail servers may blacklist you if you make too many requests of them.

In PHP I believe you can use fsockopen, fwrite and fread to perform the above steps programmatically:

$smtp_server = fsockopen("STACKOVERFLOW.COM.S9A1.PSMTP.com", 25, $errno, $errstr, 30);
fwrite($smtp_server, "helo hi\r\n");
fwrite($smtp_server, "mail from: <[email protected]>\r\n");
fwrite($smtp_server, "rcpt to: <[email protected]>\r\n");

Just adding for who might need.. Don't forget to alter the table!

ALTER TABLE table_name ADD FULLTEXT(column_name);

Have you activated your environment? Also you could try this: vscode select venv

Just include this package:

java.nio.file

And then you can use this code to write the file:

Path file = ...;
byte[] buf = ...;
Files.write(file, buf);

Use a for loop and set each one in turn.

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

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

so

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

you can use rowSums

rowSums(data) should give you what you want.

Good question here. I think you cannot terminate the script execution. Although I have never looked for it, I have been using the chrome debugger for quite a long time at work. I usually set breakpoints in my javascript code and then I debug the portion of code I'm interested in. When I finish debugging that code, I usually just run the rest of the program or refresh the browser.

If you want to prevent the rest of the script from being executed (e.g. due to AJAX calls that are going to be made) the only thing you can do is to remove that code in the console on-the-fly, thus preventing those calls from being executed, then you could execute the remaining code without problems.

I hope this helps!

P.S: I tried to find out an option for terminating the execution in some tutorials / guides like the following ones, but couldn't find it. As I said before, probably there is no such option.

Top answers don't point to an even simpler and more flexible solution.

just place a

@TestPropertySource(properties=
{"spring.autoconfigure.exclude=comma.seperated.ClassNames,com.example.FooAutoConfiguration"})
@SpringBootTest
public class MySpringTest {...}

annotation above your test class. This means other tests aren't affected by the current test's special case. If there is a configuration affecting most of your tests, then consider using the spring profile instead as the current top answer suggests.

Thanks to @skirsch for encouraging me to upgrade this from a comment to an answer.

You clone a repository with git clone [url]. Like so,

$ git clone https://github.com/libgit2/libgit2

Next matches all greater or equal to 11100:

^([1-9][1-9][1-9]\d{2}\d*|[1-9][2-9]\d{3}\d*|[2-9]\d{4}\d*|\d{6}\d*)$

For greater or equal 50:

^([5-9]\d{1}\d*|\d{3}\d*)$

See pattern and modify to any number. Also it would be great to find some recursive forward/backward operators for large numbers.

next() can read the input only till the space. It can't read two words separated by a space. Also, next() places the cursor in the same line after reading the input.

nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.

For reading the entire line you can use nextLine().

You can just pass a list of the two points you want to connect to plt.plot. To make this easily expandable to as many points as you want, you could define a function like so.

import matplotlib.pyplot as plt

x=[-1 ,0.5 ,1,-0.5]
y=[ 0.5,  1, -0.5, -1]

plt.plot(x,y, 'ro')

def connectpoints(x,y,p1,p2):
    x1, x2 = x[p1], x[p2]
    y1, y2 = y[p1], y[p2]
    plt.plot([x1,x2],[y1,y2],'k-')

connectpoints(x,y,0,1)
connectpoints(x,y,2,3)

plt.axis('equal')
plt.show()

Note, that function is a general function that can connect any two points in your list together.

To expand this to 2N points, assuming you always connect point i to point i+1, we can just put it in a for loop:

import numpy as np
for i in np.arange(0,len(x),2):
    connectpoints(x,y,i,i+1)

In that case of always connecting point i to point i+1, you could simply do:

for i in np.arange(0,len(x),2):
    plt.plot(x[i:i+2],y[i:i+2],'k-')

You have a variety of problems. First, why are you using your specific @@FETCH_STATUS values? It should just be @@FETCH_STATUS = 0.

Second, you are not selecting your inner Cursor into anything. And I cannot think of any circumstance where you would select all fields in this way - spell them out!

Here's a sample to go by. Folder has a primary key of "ClientID" that is also a foreign key for Attend. I'm just printing all of the Attend UIDs, broken down by Folder ClientID:

Declare @ClientID int;
Declare @UID int;

DECLARE Cur1 CURSOR FOR
    SELECT ClientID From Folder;

OPEN Cur1
FETCH NEXT FROM Cur1 INTO @ClientID;
WHILE @@FETCH_STATUS = 0
BEGIN
    PRINT 'Processing ClientID: ' + Cast(@ClientID as Varchar);
    DECLARE Cur2 CURSOR FOR
        SELECT UID FROM Attend Where ClientID=@ClientID;
    OPEN Cur2;
    FETCH NEXT FROM Cur2 INTO @UID;
    WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT 'Found UID: ' + Cast(@UID as Varchar);
        FETCH NEXT FROM Cur2 INTO @UID;
    END;
    CLOSE Cur2;
    DEALLOCATE Cur2;
    FETCH NEXT FROM Cur1 INTO @ClientID;
END;
PRINT 'DONE';
CLOSE Cur1;
DEALLOCATE Cur1;

Finally, are you SURE you want to be doing something like this in a stored procedure? It is very easy to abuse stored procedures and often reflects problems in characterizing your problem. The sample I gave, for example, could be far more easily accomplished using standard select calls.

If you use the gson.JsonObject you can have something like that:

import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

String jsonString = "{'test1':'value1','test2':{'id':0,'name':'testName'}}"
JsonObject jsonObject = (JsonObject) jsonParser.parse(jsonString)

My approach was similar to @SoftwareFactor, but different, perhaps because I'm running a different OS, Windows Server 2012. These steps worked for me.

Control Panel > System and Security > Administrative Tools > Services, right-click SQL Server Browser > Properties > General tab, change Startup type to Automatic, click Apply button, then click Start button in Service Status area.

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

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

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

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

AClass[] array = {object1, object2}

actually means

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

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

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

In addition to @Bikesh M Annur's answer, be sure to update your support libraries. Previously I was using 23.1.1 and nothing happened. Updating it to 23.3.0 did the trick.

Just use the function for parsing a CSV file

http://php.net/manual/en/function.fgetcsv.php

$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
  while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    $num = count($data);
    echo "<p> $num fields in line $row: <br /></p>\n";
    $row++;
    for ($c=0; $c < $num; $c++) {
        echo $data[$c] . "<br />\n";
    }
  }
  fclose($handle);
}

var sibling = node.nextSibling;

This will return the sibling immediately after it, or null no more siblings are available. Likewise, you can use previousSibling.

[Edit] On second thought, this will not give the next div tag, but the whitespace after the node. Better seems to be

var sibling = node.nextElementSibling;

There also exists a previousElementSibling.

I had the same problem.

The problem was:

pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error

Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.

Maybe a pip install --ignore-installed would have worked.

Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.

string.find("substring") will help you. This function returns -1 when there is no substring.

There is also an 'E' status

E = File existed before update

This can happen if you have manually created a folder that would have been created by performing an update.

textarea { height: auto; }

<textarea rows="10"></textarea>

This will trigger the browser to set the height of the textarea EXACTLY to the amount of rows plus the paddings around it. Setting the CSS height to an exact amount of pixels leaves arbitrary whitespaces.

I did another attempt to simplify this and achieve it without the necessity of a container.

HTML

.box1 {
  background-color: #ff0000;
  width: 200px;
  float: left;
}

.box2 {
  background-color: #00ff00;
  width: 200px;
  float: right;
}

.box3 {
  background-color: #0fffff;
  width: 200px;
  margin: 0 auto;
}

CSS

  .box1 {
  background-color: #ff0000;
  width: 200px;
  float: left;
}

.box2 {
  background-color: #00ff00;
  width: 200px;
  float: right;
}

.box3 {
  background-color: #0fffff;
  width: 200px;
  margin: 0 auto;
}

Source code of CSS/JS we usually minified/compress. Now if we want to debug those minified files then we have to add following line at the end of minified file

/*# sourceMappingURL=bootstrap.min.css.map */

This tells compiler where is source file actually mapped.

In the case of JS its make sense
but in the case of CSS, its actually debugging of SCSS.

To Remove Warning: remove /*# sourceMappingURL=bootstrap.min.css.map */ from the end of minified file, .

Semicolon should be at the end of the class definition rather than after the name:

class WordGame
{
};

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="2dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:paddingTop="2dp"
    android:scaleType="fitXY"
    android:src="?android:attr/listDivider" />

The string class has a constructor that takes a NULL-terminated C-string:

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

// or
str = arr;

I found a solution for myself

var acService = new google.maps.places.AutocompleteService();
var autocompleteItems = [];

acService.getPlacePredictions({
    types: ['(regions)']
}, function(predictions) {
    predictions.forEach(function(prediction) {
        if (prediction.types.some(function(x) {
                return x === "country" || x === "administrative_area1" || x === "locality";
            })) {
            if (prediction.terms.length < 3) {
                autocompleteItems.push(prediction);
            }
        }
    });
});

this solution only show city and country..

I think LayeredPane is your best bet here. You would need a third panel though to contain A and B. This third panel would be the layeredPane and then panel A and B could still have a nice LayoutManagers. All you would have to do is center B over A and there is quite a lot of examples in the Swing trail on how to do this. Tutorial for positioning without a LayoutManager.

public class Main {
    private JFrame frame = new JFrame();
    private JLayeredPane lpane = new JLayeredPane();
    private JPanel panelBlue = new JPanel();
    private JPanel panelGreen = new JPanel();
    public Main()
    {
        frame.setPreferredSize(new Dimension(600, 400));
        frame.setLayout(new BorderLayout());
        frame.add(lpane, BorderLayout.CENTER);
        lpane.setBounds(0, 0, 600, 400);
        panelBlue.setBackground(Color.BLUE);
        panelBlue.setBounds(0, 0, 600, 400);
        panelBlue.setOpaque(true);
        panelGreen.setBackground(Color.GREEN);
        panelGreen.setBounds(200, 100, 100, 100);
        panelGreen.setOpaque(true);
        lpane.add(panelBlue, new Integer(0), 0);
        lpane.add(panelGreen, new Integer(1), 0);
        frame.pack();
        frame.setVisible(true);
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main();
    }

}

You use setBounds to position the panels inside the layered pane and also to set their sizes.

Edit to reflect changes to original post You will need to add component listeners that detect when the parent container is being resized and then dynamically change the bounds of panel A and B.

So I had a project that required downloading assets from firebase storage, so I had to solve this problem myself. Here is How :

1- First, make a model data for example class Choice{}, In that class defines a String variable called image Name so it will be like that

class Choice {
    .....
    String imageName;
}

2- from a database/firebase database, go and hardcode the image names to the objects, so if you have image name called Apple.png, create the object to be

Choice myChoice = new Choice(...,....,"Apple.png");

3- Now, get the link for the assets in your firebase storage which will be something like that

gs://your-project-name.appspot.com/

like this one

4- finally, initialize your firebase storage reference and start getting the files by a loop like that

storageRef = storage.getReferenceFromUrl(firebaseRefURL).child(imagePath);

File localFile = File.createTempFile("images", "png");
storageRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {

@Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
    //Dismiss Progress Dialog\\
}

5- that's it

Same as above, might help some people.

setTimeout(() => {
  if (pushToken!=null && deviceId!=null) {
    console.log("pushToken & OS ");
    this.setState({ pushToken: pushToken});
    this.setState({ deviceId: deviceId });
    console.log("pushToken & OS "+pushToken+"\n"+deviceId);
  }
}, 1000);

Try Boost::Program Options. It allows you to read and parse command lines as well as config files.

Make a batch file "Pc.bat" as, typeperf -sc 1 "\mukit\processor(_Total)\%% Processor Time"

You can use the class MProcess,

/*
 *Md. Mukit Hasan
 *CSE-JU,35
 **/
import java.io.*;

public class MProcessor {
public MProcessor() {
String s;
try {
Process ps = Runtime.getRuntime().exec("Pc.bat");
BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
while((s = br.readLine()) != null) {
System.out.println(s);
}
}
catch( Exception ex ) {
System.out.println(ex.toString());
}
}

}

Then after some string manipulation, you get the CPU use. You can use the same process for other tasks.

--Mukit Hasan

An alternative way is to use MySql Workbench. Go to Administration -> Users and privileges -> and change 'localhost' with '%' in 'Limit to Host Matching' (From host) attribute for users you wont to give remote access Or create new user ( Add account button ) with '%' on this attribute instead localhost.

json_encode is available in php > 5.2.0:

Applying recursion to reorder items in an arraylist

public class ArrayListUtils {
            public static <T> void reArrange(List<T> list,int from, int to){
                if(from != to){
                     if(from > to)
                        reArrange(list,from -1, to);
                      else
                        reArrange(list,from +1, to);

                     Collections.swap(list, from, to);
                }
            }
    }

Here, check out this function:

function seo_friendly_url($string){
    $string = str_replace(array('[\', \']'), '', $string);
    $string = preg_replace('/\[.*\]/U', '', $string);
    $string = preg_replace('/&(amp;)?#?[a-z0-9]+;/i', '-', $string);
    $string = htmlentities($string, ENT_COMPAT, 'utf-8');
    $string = preg_replace('/&([a-z])(acute|uml|circ|grave|ring|cedil|slash|tilde|caron|lig|quot|rsquo);/i', '\\1', $string );
    $string = preg_replace(array('/[^a-z0-9]/i', '/[-]+/') , '-', $string);
    return strtolower(trim($string, '-'));
}

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

You just have to change the second line of your second code-block from

{% if myVar is in_array(array_keys(someOtherArray)) %}

to

{% if myVar in someOtherArray|keys %}

in is the containment-operator and keys a filter that returns an arrays keys.

Auto detect your proxy settings and inject them in all your vagrant VM

install the proxy plugin

vagrant plugin install vagrant-proxyconf

add this conf to you private/user VagrantFile (it will be executed for all your projects) :

vi $HOME/.vagrant.d/Vagrantfile

Vagrant.configure("2") do |config|
  puts "proxyconf..."
  if Vagrant.has_plugin?("vagrant-proxyconf")
    puts "find proxyconf plugin !"
    if ENV["http_proxy"]
      puts "http_proxy: " + ENV["http_proxy"]
      config.proxy.http     = ENV["http_proxy"]
    end
    if ENV["https_proxy"]
      puts "https_proxy: " + ENV["https_proxy"]
      config.proxy.https    = ENV["https_proxy"]
    end
    if ENV["no_proxy"]
      config.proxy.no_proxy = ENV["no_proxy"]
    end
  end
end

now up your VM !

Use Java 8:

map.entrySet().forEach(entry -> System.out.println(entry.getValue()));

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

Another way to push items into array using Mongoose is- $addToSet, if you want only unique items to be pushed into array. $push operator simply adds the object to array whether or not the object is already present, while $addToSet does that only if the object is not present in the array so as not to incorporate duplicacy.

PersonModel.update(
  { _id: person._id }, 
  { $addToSet: { friends: friend } }
);

This will look for the object you are adding to array. If found, does nothing. If not, adds it to the array.

References:

• $addToSet
• MongooseArray.prototype.addToSet()

Java script:

use elementid. selectedIndex() function to get the selected index

In general, no. However, a struct declared as file-scope or static in a function /will/ be initialized to 0 (just like all other variables of those scopes):

int x; // 0
int y = 42; // 42
struct { int a, b; } foo; // 0, 0

void foo() {
  struct { int a, b; } bar; // undefined
  static struct { int c, d; } quux; // 0, 0
}

It's my solution on Java:

public class CombinatorialUtils {

    public static void main(String[] args) {
        List<String> alphabet = new ArrayList<>();
        alphabet.add("1");
        alphabet.add("2");
        alphabet.add("3");
        alphabet.add("4");

        for (List<String> strings : permutations(alphabet)) {
            System.out.println(strings);
        }
        System.out.println("-----------");
        for (List<String> strings : combinations(alphabet)) {
            System.out.println(strings);
        }
    }

    public static List<List<String>> combinations(List<String> alphabet) {
        List<List<String>> permutations = permutations(alphabet);
        List<List<String>> combinations = new ArrayList<>(permutations);

        for (int i = alphabet.size(); i > 0; i--) {
            final int n = i;
            combinations.addAll(permutations.stream().map(strings -> strings.subList(0, n)).distinct().collect(Collectors.toList()));
        }
        return combinations;
    }

    public static <T> List<List<T>> permutations(List<T> alphabet) {
        ArrayList<List<T>> permutations = new ArrayList<>();
        if (alphabet.size() == 1) {
            permutations.add(alphabet);
            return permutations;
        } else {
            List<List<T>> subPerm = permutations(alphabet.subList(1, alphabet.size()));
            T addedElem = alphabet.get(0);
            for (int i = 0; i < alphabet.size(); i++) {
                for (List<T> permutation : subPerm) {
                    int index = i;
                    permutations.add(new ArrayList<T>(permutation) {{
                        add(index, addedElem);
                    }});
                }
            }
        }
        return permutations;
    }
}

Just in case your output need to be fixed length of 3-digit , i.e. for number run up to 1000 or more (reserved fixed length), don't forget to add mod 1000 on it .

yourNumber=1001;
yourString= yourNumber.ToString("D3");        // "1001" 
yourString= (yourNumber%1000).ToString("D3"); // "001" truncated to 3-digit as expected

Callable and Runnable both is similar to each other and can use in implementing thread. In case of implementing Runnable you must implement run() method but in case of callable you must need to implement call() method, both method works in similar ways but callable call() method have more flexibility.There is some differences between them.

Difference between Runnable and callable as below--

1) The run() method of runnable returns void, means if you want your thread return something which you can use further then you have no choice with Runnable run() method. There is a solution 'Callable', If you want to return any thing in form of object then you should use Callable instead of Runnable. Callable interface have method 'call()' which returns Object.

Method signature - Runnable->

public void run(){}

Callable->

public Object call(){}

2) In case of Runnable run() method if any checked exception arises then you must need to handled with try catch block, but in case of Callable call() method you can throw checked exception as below

 public Object call() throws Exception {}

3) Runnable comes from legacy java 1.0 version, but callable came in Java 1.5 version with Executer framework.

If you are familiar with Executers then you should use Callable instead of Runnable.

Hope you understand.

Result has an optional $type parameter which decides what type of result is returned. By default ($type = "object"), it returns an object (result_object()). It can be set to "array", then it will return an array of result, that being equivalent of caling result_array(). The third version accepts a custom class to use as a result object.

The code from CodeIgniter:

/**
* Query result. Acts as a wrapper function for the following functions.
*
* @param string $type 'object', 'array' or a custom class name
* @return array
*/
public function result($type = 'object')
{
    if ($type === 'array')
    {
        return $this->result_array();
    }
    elseif ($type === 'object')
    {
        return $this->result_object();
    }
    else
    {
        return $this->custom_result_object($type);
    }
}

Arrays are technically faster, but they are not objects. It depends where do you want to use the result. Most of the time, arrays are sufficient.

var datestr = '2012.08.10';
var timestamp = (new Date(datestr.split(".").join("-")).getTime())/1000;

Useful to quickly print entries in a HashMap

System.out.println(Arrays.toString(map.entrySet().toArray()));

The way I think of it is like this: A unit test establishes that the code does what you intended the code to do (e.g. you wanted to add parameter a and b, you in fact add them, and don't subtract them), functional tests test that all of the code works together to get a correct result, so that what you intended the code to do in fact gets the right result in the system.

I think use this is better:

os.path.realpath(__file__).rsplit('/', X)[0]


In [1]: __file__ = "/aParent/templates/blog1/page.html"

In [2]: os.path.realpath(__file__).rsplit('/', 3)[0]
Out[3]: '/aParent'

In [4]: __file__ = "/aParent/templates/blog1/page.html"

In [5]: os.path.realpath(__file__).rsplit('/', 1)[0]
Out[6]: '/aParent/templates/blog1'

In [7]: os.path.realpath(__file__).rsplit('/', 2)[0]
Out[8]: '/aParent/templates'

In [9]: os.path.realpath(__file__).rsplit('/', 3)[0]
Out[10]: '/aParent'

see also "Forking vs. Branching in GitHub", "What is the difference between origin and upstream in GitHub")

Couple tips on pull-requests:

Assuming that you have first forked a repo, here is what you should do in that fork that you own:

• create a branch: isolate your modifications in a branch. Don't create a pull request from master, where you could be tempted to accumulate and mix several modifications at once.
• rebase that branch: even if you already did a pull request from that branch, rebasing it on top of origin/master (making sure your patch is still working) will update the pull request automagically (no need to click on anything)
• update that branch: if your pull request is rejected, you simply can add new commits, and/or redo your history completely: it will activate your existing pull request again.
• "focus" that branch: i.e., make its topic "tight", don't modify thousands of class and the all app, only add or fix a well-defined feature, keeping the changes small.
• delete that branch: once accepted, you can safely delete that branch on your fork (and git remote prune origin). The GitHub GUI will propose for you to delete your branch in your pull-request page.

Note: to write the Pull-Request itself, see "How to write the perfect pull request" (January 2015, GitHub)

March 2016: New PR merge button option: see "Github squash commits from web interface on pull request after review comments?".

The maintainer of the repo can chose to merge --squash those PR commits.

After a Pull Request

Regarding the last point, since April, 10th 2013, "Redesigned merge button", the branch is deleted for you:

Deleting branches after you merge has also been simplified.
Instead of confirming the delete with an extra step, we immediately remove the branch when you delete it and provide a convenient link to restore the branch in the event you need it again.

That confirms the best practice of deleting the branch after merging a pull request.

pull-request vs. request-pull

• pull request isn't an official "git" term.
  Git uses the request-pull(!) command to build a request for merging:
  It "summarizes the changes between two commits to the standard output, and includes the given URL in the generated summary."
  Github launches its own version since day one (February 2008), but redesigned that feature in May 2010, stating that:

  Pull Request = Compare View + Issues + Commit comments
  

e-notes for "reposotory" (sic)

<humour>

That (pull request) isn't even defined properly by GitHub!

Fortunately, a true business news organization would know, and there is an e-note in order to replace pull-replace by 'e-note':

So if your reposotory needs a e-note... ask Fox Business. They are in the know.

</humour>

This will do what you want:

select * 
  from orders_products 
       INNER JOIN orders 
          ON orders_products.orders_id = orders.orders_id
 where products_id in (180, 181);

you can do

followers_df.index = range(20)

The task gives you all the goodness of the task API:

• Adding continuations (Task.ContinueWith)
• Waiting for multiple tasks to complete (either all or any)
• Capturing errors in the task and interrogating them later
• Capturing cancellation (and allowing you to specify cancellation to start with)
• Potentially having a return value
• Using await in C# 5
• Better control over scheduling (if it's going to be long-running, say so when you create the task so the task scheduler can take that into account)

Note that in both cases you can make your code slightly simpler with method group conversions:

DataInThread = new Thread(ThreadProcedure);
// Or...
Task t = Task.Factory.StartNew(ThreadProcedure);

What is gone is gone. The only protection I know of is regular backup.

The awk variant :

awk '1;/CLIENTSCRIPT=/{print "CLIENTSCRIPT2=\"hello\""}' file

SET @cnt=0; 
SELECT s.* 
FROM   (SELECT ( @cnt := @cnt + 1 ) AS rank, 
               a.* 
        FROM   one AS a 
        ORDER  BY a.salary DESC) AS s 
WHERE  s.rank = '3'; 

Why not add "display: none;" to the divs style attribute? Thats all JQuery's .hide() function does.

I solved the issue by using overflow-x:hidden; as follows

@media screen and (max-width: 441px){

#end_screen { (NOte:-the end_screen is the wrapper div for all other div's inside it.)
  overflow-x: hidden;
   }
 }

structure is as follows

1st div end_screen >> inside it >> end_screen_2(div) >> inside it >> end_screen_2.

'end_screen is the wrapper of end_screen_1 and end_screen_2 div's

This command installs npm package username/package from specific git commit:

npm install https://github.com/username/package#3d0a21cc

Here 3d0a21cc is first 8 characters of commit hash.

all(getattr(someTime,x)==getattr(today(),x) for x in ['year','month','day'])

One should compare using .date(), but I leave this method as an example in case one wanted to, for example, compare things by month or by minute, etc.

perl one-liner alert

just for fun... print only one line after match

perl -lne '$next = ($.+1) if /match/; $. == $next && print' data.txt

even more fun... print the next ten lines after match

perl -lne 'push @nexts, (($.+1)..($.+10)) if /match/; $. ~~ @nexts && print' data.txt

kinda cheating though since there's actually two commands

HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.

More details here.

Use the file browser "Total Commander" instead.

1. Enable the "show hidden/system files" setting in Total Commander
2. Browse to "c:\windows\assembly"
3. copy

The information there is I think partially correct:

That's not true. An URL can use spaces. Nothing defines that a space is replaced with a + sign.

As you noted, an URL can NOT use spaces. The HTTP request would get screwed over. I'm not sure where the + is defined, though %20 is standard.

<div>
    <input type="checkbox">
    <img src="/image.png" />
</div>

input[type="checkbox"]
{
    margin-top: -50%;
    vertical-align: middle;
}

CSS itself doesn't have conditional statements, but here's a hack involving custom properties (a.k.a. "css variables").

In this trivial example, you want to apply a padding based on a certain condition—like an "if" statement.

:root   { --is-big: 0; }

.is-big { --is-big: 1; }

.block {
  padding: calc(
    4rem * var(--is-big) +
    1rem * (1 - var(--is-big))
  );
}

So any .block that's an .is-big or that's a descendant of one will have a padding of 4rem, while all other blocks will only have 1rem. Now I call this a "trivial" example because it can be done without the hack.

.block {
  padding: 1rem;
}

.is-big .block,
.block.is-big {
  padding: 4rem;
}

But I will leave its applications to your imagination.

I guess a little more convenient and structured way is to use Html helper. In your view it can be look like:

@{
 var htmlAttr = new Dictionary<string, object>();
 htmlAttr.Add("id", strElementId);
 if (!CSSClass.IsEmpty())
 {
   htmlAttr.Add("class", strCSSClass);
 }
}

@* ... *@

@Html.TextBox("somename", "", htmlAttr)

If this way will be useful for you i recommend to define dictionary htmlAttr in your model so your view doesn't need any @{ } logic blocks (be more clear).

For an uglier version of unshift use splice:

TheArray.splice(0, 0, TheNewObject);

If you have some common methods that can be used by multiple classes go for abstract classes. Else if you want the classes to follow some definite blueprint go for interfaces.

Following examples demonstrate this.

Abstract class in Java:

abstract class Animals
{
    // They all love to eat. So let's implement them for everybody
    void eat()
    {
        System.out.println("Eating...");
    }
    // The make different sounds. They will provide their own implementation.
    abstract void sound();
}
 
class Dog extends Animals
{
    void sound()
    {
        System.out.println("Woof Woof");
    }
}
 
class Cat extends Animals
{
    void sound()
    {
        System.out.println("Meoww");
    }
}

Following is an implementation of interface in Java:

interface Shape
{
    void display();
    double area();
}
 
class Rectangle implements Shape 
{
    int length, width;
    Rectangle(int length, int width)
    {
        this.length = length;
        this.width = width;
    }
    @Override
    public void display() 
    {
        System.out.println("****\n* *\n* *\n****"); 
    }
    @Override
    public double area() 
    {
        return (double)(length*width);
    }
} 
 
class Circle implements Shape 
{
    double pi = 3.14;
    int radius;
    Circle(int radius)
    {
        this.radius = radius;
    }
    @Override
    public void display() 
    {
        System.out.println("O"); // :P
    }
    @Override
    public double area() 
    { 
        return (double)((pi*radius*radius)/2);
    }
}

Some Important Key points in a nutshell:

1. The variables declared in Java interface are by default final. Abstract classes can have non-final variables.

2. The variables declared in Java interface are by default static. Abstract classes can have non-static variables.

3. Members of a Java interface are public by default. A Java abstract class can have the usual flavors of class members like private, protected, etc..

The docs describe the attributes available on the request. In most common cases request.data will be empty because it's used as a fallback:

request.data Contains the incoming request data as string in case it came with a mimetype Flask does not handle.

• request.args: the key/value pairs in the URL query string
• request.form: the key/value pairs in the body, from a HTML post form, or JavaScript request that isn't JSON encoded
• request.files: the files in the body, which Flask keeps separate from form. HTML forms must use enctype=multipart/form-data or files will not be uploaded.
• request.values: combined args and form, preferring args if keys overlap
• request.json: parsed JSON data. The request must have the application/json content type, or use request.get_json(force=True) to ignore the content type.

All of these are MultiDict instances (except for json). You can access values using:

• request.form['name']: use indexing if you know the key exists
• request.form.get('name'): use get if the key might not exist
• request.form.getlist('name'): use getlist if the key is sent multiple times and you want a list of values. get only returns the first value.

In cryptography there are two types of algorithms used:

Symmetric algorithms

A single key is used to encrypt data. When encrypted with the key, the data can be decrypted using the same key. If, for example, Mary encrypts a message using the key "my-secret" and sends it to John, he will be able to decrypt the message correctly with the same key "my-secret".

Asymmetric algorithms

Two keys are used to encrypt and decrypt messages. While one key(public) is used to encrypt the message, the other key(private) can only be used to decrypt it. So, John can generate both public and private keys, then send only the public key to Mary to encrypt her message. The message can only be decrypted using the private key.

HS256 and RS256 Scenario

These algorithms are NOT used to encrypt/decryt data. Rather they are used to verify the origin or the authenticity of the data. When Mary needs to send an open message to Jhon and he needs to verify that the message is surely from Mary, HS256 or RS256 can be used.

HS256 can create a signature for a given sample of data using a single key. When the message is transmitted along with the signature, the receiving party can use the same key to verify that the signature matches the message.

RS256 uses pair of keys to do the same. A signature can only be generated using the private key. And the public key has to be used to verify the signature. In this scenario, even if Jack finds the public key, he cannot create a spoof message with a signature to impersonate Mary.

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

Packages are just .xar archives with a different extension and a specified file hierarchy. Unfortunately, part of that file hierarchy is a cpio.gz archive of the actual installables, and usually that's what you want to edit. And there's also a Bom file that includes information on the files inside that cpio archive, and a PackageInfo file that includes summary information.

If you really do just need to edit one of the info files, that's simple:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
# edit stuff
xar -cf ../Foo-new.pkg *

But if you need to edit the installable files:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
cd foo.pkg
cat Payload | gunzip -dc |cpio -i
# edit Foo.app/*
rm Payload
find ./Foo.app | cpio -o | gzip -c > Payload
mkbom Foo.app Bom # or edit Bom
# edit PackageInfo
rm -rf Foo.app
cd ..
xar -cf ../Foo-new.pkg

I believe you can get mkbom (and lsbom) for most linux distros. (If you can get ditto, that makes things even easier, but I'm not sure if that's nearly as ubiquitously available.)

I think it makes clear with the namespace, as we can create our own attributes and if the user specified attribute is the same as the Android one it avoid the conflict of the namespace.

Try making

NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"MyFile"];

as

NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"MyFile.txt"];

Here is a bare bones main method that accepts a command line argument, you may need to append your own error checking or mold it to how you see fit.

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;

public class DeleteFiles {

/**
 * @param intitial arguments take in a source to read from and a 
 * destination to read to
 */
    public static void main(String[] args)
                     throws FileNotFoundException,IOException {
        File src = new File(args[0]);
        if (!src.exists() ) {
            System.out.println("FAILURE!");
        }else{
            // Gathers files in directory
            File[] a = src.listFiles();
            for (int i = 0; i < a.length; i++) {
                //Sends files to recursive deletion method
                fileDelete(a[i]);
            }
            // Deletes original source folder
            src.delete();
            System.out.println("Success!");
        }
    }

    /**
     * @param srcFile Source file to examine
     * @throws FileNotFoundException if File not found
     * @throws IOException if File not found
     */
    private static void fileDelete(File srcFile)
                     throws FileNotFoundException, IOException {
        // Checks if file is a directory
        if (srcFile.isDirectory()) {
            //Gathers files in directory
            File[] b = srcFile.listFiles();
            for (int i = 0; i < b.length; i++) {
                //Recursively deletes all files and sub-directories
                fileDelete(b[i]);
            }
            // Deletes original sub-directory file
            srcFile.delete();
        } else {
            srcFile.delete();
        }
    }
}

I hope that helps!

An idea could be to use the optgroup. In my case found it better than the disabled approach. It's less confusing for the user than seeing the disabled option I think.

<select id="q1" v-model="selected" v-on:change="setCPost1(selected)">
  <option value="0"></option>
  <template
    v-for="(child, idx) in getLevel1"
    v-bind:value="child.id"      
  >

  <optgroup v-bind:value="child.id" :key="idx"
  :label="child.label"
  v-if="child.label_line_two"
  >
  </optgroup>

  <option v-bind:value="child.id" :key="idx"  v-if="!child.label_line_two"
  >
  {{ child.label }}  
  </option>

  <option v-bind:value="child.id" :key="idx" v-if="child.label_line_two"
  style="font-style:italic">
  {{ child.label_line_two }}
  </option>


  </template>
</select>

An external component sounds cool like Vue Select, but I wanted to stick with the native html select at the moment.

With this chunk of code, you will get something like this

extension UIButton {
    func alignTextUnderImage() {
        guard let imageView = imageView else {
                return
        }
        self.contentVerticalAlignment = .Top
        self.contentHorizontalAlignment = .Center
        let imageLeftOffset = (CGRectGetWidth(self.bounds) - CGRectGetWidth(imageView.bounds)) / 2//put image in center
        let titleTopOffset = CGRectGetHeight(imageView.bounds) + 5
        self.imageEdgeInsets = UIEdgeInsetsMake(0, imageLeftOffset, 0, 0)
        self.titleEdgeInsets = UIEdgeInsetsMake(titleTopOffset, -CGRectGetWidth(imageView.bounds), 0, 0)
    }
}

Type IF /? to get help about if, it clearly explains how to use IF EXIST.

To delete a complete tree except some folders, see the answer of this question: Windows batch script to delete everything in a folder except one

Finally copying just means calling COPY and calling another bat file can be done like this:

MYOTHERBATFILE.BAT sync.bat myprogram.ini

you could have both of them use a "corpo_button" class, or something like that, and then in $(".corpo_button").click(...) just call $(this).toggleClass("corpo_buttons_asia corpo_buttons_global");

From the official Swift programming guide:

Global variables are variables that are defined outside of any function, method, closure, or type context. Global constants and variables are always computed lazily.

You can define it in any file and can access it in current module anywhere. So you can define it somewhere in the file outside of any scope. There is no need for static and all global variables are computed lazily.

 var yourVariable = "someString"

You can access this from anywhere in the current module.

However you should avoid this as Global variables are not good for application state and mainly reason of bugs.

As shown in this answer, in Swift you can encapsulate them in struct and can access anywhere. You can define static variables or constant in Swift also. Encapsulate in struct

struct MyVariables {
    static var yourVariable = "someString"
}

You can use this variable in any class or anywhere

let string = MyVariables.yourVariable
println("Global variable:\(string)")

//Changing value of it
MyVariables.yourVariable = "anotherString"

here is a version that handles multiple requests, also checks for cancelled status in callback to suppress errors in error block. (in Typescript)

controller level:

    requests = new Map<string, ng.IDeferred<{}>>();

in my http get:

    getSomething(): void {
        let url = '/api/someaction';
        this.cancel(url); // cancel if this url is in progress

        var req = this.$q.defer();
        this.requests.set(url, req);
        let config: ng.IRequestShortcutConfig = {
            params: { id: someId}
            , timeout: req.promise   // <--- promise to trigger cancellation
        };

        this.$http.post(url, this.getPayload(), config).then(
            promiseValue => this.updateEditor(promiseValue.data as IEditor),
            reason => {
                // if legitimate exception, show error in UI
                if (!this.isCancelled(req)) {
                    this.showError(url, reason)
                }
            },
        ).finally(() => { });
    }

helper methods

    cancel(url: string) {
        this.requests.forEach((req,key) => {
            if (key == url)
                req.resolve('cancelled');
        });
        this.requests.delete(url);
    }

    isCancelled(req: ng.IDeferred<{}>) {
        var p = req.promise as any; // as any because typings are missing $$state
        return p.$$state && p.$$state.value == 'cancelled';
    }

now looking at the network tab, i see that it works beatuifully. i called the method 4 times and only the last one went through.

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

I used JSONObject as shown below in Servlet.

    JSONObject jsonReturn = new JSONObject();

    NhAdminTree = AdminTasks.GetNeighborhoodTreeForNhAdministrator( connection, bwcon, userName);

    map = new HashMap<String, String>();
    map.put("Status", "Success");
    map.put("FailureReason", "None");
    map.put("DataElements", "2");

    jsonReturn = new JSONObject();
    jsonReturn.accumulate("Header", map);

    List<String> list = new ArrayList<String>();
    list.add(NhAdminTree);
    list.add(userName);

    jsonReturn.accumulate("Elements", list);

The Servlet returns this JSON object as shown below:

    response.setContentType("application/json");
    response.getWriter().write(jsonReturn.toString());

This Servlet is called from Browser using AngularJs as below

$scope.GetNeighborhoodTreeUsingPost = function(){
    alert("Clicked GetNeighborhoodTreeUsingPost : " + $scope.userName );

    $http({

        method: 'POST',
        url : 'http://localhost:8080/EPortal/xlEPortalService',
        headers: {
           'Content-Type': 'application/json'
         },
        data : {
            'action': 64,
            'userName' : $scope.userName
        }
    }).success(function(data, status, headers, config){
        alert("DATA.header.status : " + data.Header.Status);
        alert("DATA.header.FailureReason : " + data.Header.FailureReason);
        alert("DATA.header.DataElements : " + data.Header.DataElements);
        alert("DATA.elements : " + data.Elements);

    }).error(function(data, status, headers, config) {
        alert(data + " : " + status + " : " + headers + " : " + config);
    });

};

This code worked and it is showing correct data in alert dialog box:

Data.header.status : Success

Data.header.FailureReason : None

Data.header.DetailElements : 2

Data.Elements : Coma seperated string values i.e. NhAdminTree, userName

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

I was missing the MSVCR110.dll. Which I corrected. I could run php from the command line but not the web server. Then I clicked on php-cgi.exe and it gave me the answer. The php5.dll was missing (I downloaded the wrong copy). So for my 2012 IIS box I re-installed using php's x86 non thread safe zip.

Assuming such a query would return a single row, you could use either

select @EmpId = Id from dbo.Employee

Or

set @EmpId = (select Id from dbo.Employee)

Abstraction

We use many abstractions in our day-to-day lives.Consider a car.Most of us have an abstract view of how a car works.We know how to interact with it to get it to do what we want it to do: we put in gas, turn a key, press some pedals, and so on. But we don't necessarily understand what is going on inside the car to make it move and we don't need to. Millions of us use cars everyday without understanding the details of how they work.Abstraction helps us get to school or work!

A program can be designed as a set of interacting abstractions. In Java, these abstractions are captured in classes. The creator of a class obviusly has to know its interface, just as the driver of a car can use the vehicle without knowing how the engine works.

Encapsulation

Consider a Banking system.Banking system have properties like account no,account type,balance ..etc. If someone is trying to change the balance of the account,attempt can be successful if there is no encapsulation. Therefore encapsulation allows class to have complete control over their properties.

if (n === Object(n)) {

In iOS 9.2 they renamed the 'Profiles' to 'Device Management'

This is how you should do it now:

1. Settings -> General -> Device Management
2. Verify the app

try to use this pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({ name: 'values',  pure: false })
export class ValuesPipe implements PipeTransform {

    return Object.keys(value).map(key => value[key]);
  }
}

<div *ngFor="#value of object | values"> </div>

As of Chrome 52, the UI has changed. When the Developer Tools dialog is open, you select the vertical ellipsis and can then choose the docking position:

Select the icon on the left to open the Chrome Developer Tools in a new window:

Previously

Click and hold the button next to the close button of the Developer Tool in order to reveal the "Undock into separate window" option.

Note: A "press" is not enough in that state.

If you already know beforehand how many columns your new DataTable would have, you can do something like this:

DataTable matrix = ... // get matrix values from db

DataTable newDataTable = new DataTable();
newDataTable.Columns.Add("c_to", typeof(string));
newDataTable.Columns.Add("p_to", typeof(string));

var query = from r in matrix.AsEnumerable()
            where r.Field<string>("c_to") == "foo" &&
                    r.Field<string>("p_to") == "bar"
            let objectArray = new object[]
            {
                r.Field<string>("c_to"), r.Field<string>("p_to")
            }
            select objectArray;

foreach (var array in query)
{
    newDataTable.Rows.Add(array);
}

There are three options for copying it if this is a one off:

1. Use a db_link (I think it is still in contrib)
2. Have the application do the work.
3. Export/import

If this is an ongoing need, the answers are:

1. Change to schemas in the same DB

Using the Windows FTP client you would want to use the -s:filename option to specify a script for the FTP client to run. The documentation specifically points out that you should not try to pipe input into the FTP client with a < character.

Execution of the script will start immediately, so it does work for username/password.

However, the security of this setup is questionable since you now have a username and password for the FTP server visible to anyone who decides to look at your batch file.

Either way, you can generate the script file on the fly from the batch file and then pass it to the FTP client like so:

@echo off

REM Generate the script. Will overwrite any existing temp.txt
echo open servername> temp.txt
echo username>> temp.txt
echo password>> temp.txt
echo get %1>> temp.txt
echo quit>> temp.txt

REM Launch FTP and pass it the script
ftp -s:temp.txt

REM Clean up.
del temp.txt

Replace servername, username, and password with your details and the batch file will generate the script as temp.txt launch ftp with the script and then delete the script.

If you are always getting the same file you can replace the %1 with the file name. If not you just launch the batchfile and provide the name of the file to get as an argument.

Here's some future-proof code for browsers that may lack escape/unescape(). Note that IE 9 and older don't support atob/btoa(), so you'd need to use custom base64 functions for them.

// Polyfill for escape/unescape
if( !window.unescape ){
    window.unescape = function( s ){
        return s.replace( /%([0-9A-F]{2})/g, function( m, p ) {
            return String.fromCharCode( '0x' + p );
        } );
    };
}
if( !window.escape ){
    window.escape = function( s ){
        var chr, hex, i = 0, l = s.length, out = '';
        for( ; i < l; i ++ ){
            chr = s.charAt( i );
            if( chr.search( /[A-Za-z0-9\@\*\_\+\-\.\/]/ ) > -1 ){
                out += chr; continue; }
            hex = s.charCodeAt( i ).toString( 16 );
            out += '%' + ( hex.length % 2 != 0 ? '0' : '' ) + hex;
        }
        return out;
    };
}

// Base64 encoding of UTF-8 strings
var utf8ToB64 = function( s ){
    return btoa( unescape( encodeURIComponent( s ) ) );
};
var b64ToUtf8 = function( s ){
    return decodeURIComponent( escape( atob( s ) ) );
};

A more comprehensive example for UTF-8 encoding and decoding can be found here: http://jsfiddle.net/47zwb41o/

To remove this error, in your html form you should do the following in enctype:

<form  enctype="multipart/form-data">

The following down is the cause of that error i.e if you start with form-data in enctype, so you should start with multipart:

<form enctype="form-data/multipart">

Following Nick Craver's solution, setting the element's visibility allows it to get accurate dimensions. I've used this solution very very often. However, having to reset the styles manually, I've come to find this cumbersome, given that modifying the element's initial positioning/display in my css through development, I often forget to update the related javascript code. The following code doesn't reset the styles per say, but removes the inline styles added by javascript:

$("#myDiv")
.css({
    position:   'absolute',
    visibility: 'hidden',
    display:    'block'
});

optionHeight = $("#myDiv").height();
optionWidth = $("#myDiv").width();

$("#myDiv").attr('style', '');

The only assumption here is that there can't be other inline styles or else they will be removed aswell. The benefit here, however, is that the element's styles are returned to what they were in the css stylesheet. As a consequence, you can write this up as a function where an element is passed through, and a height or width is returned.

Another issue I've found of setting the styles inline via js is that when dealing with transitions through css3, you become forced to adapt your style rules' weights to be stronger than an inline style, which can be frustrating sometimes.

Clear() set the Text property to nothing. So txtbox1.Text = Nothing does the same thing as clear. An empty string (also available through String.Empty) is not a null reference, but has no value of course.

To use C# (C# Script was initialized at 2015) on ASPX page you can make use the following syntax.

Start Tag:- <% End tag:- %> Please make sure that all the C# code must reside inside this <%%> .

Syntax Example:-

• <%@ Import Namespace="System.Web.UI.WebControls" %> (For importing Namespace) Reference to some basic namespaces for working with ASPX page.

  <%@ Import Namespace="System.Web.UI.WebControls" %> <%@ Import Namespace="System.Diagnostics" %> <%@ Import Namespace="System" %> <%@ Import Namespace="System.Web" %> <%@ Import Namespace="System.Web.UI" %> <%@ Import Namespace="System.IO" %>

C# Code:-

`<%
if (Session["New"] != null)
{
    Page.Title = ActionController.GetName(Session["New"].ToString());
}
%>`

Features of C# Script:

• No need of compilation. Run time execution is occurred like Java Script.

Before using C# script make sure the following things:-

• You are on WebForm. Not on WebForm with master page.
• If you are in WebForm with master page make sure that you have written your C# script at Master page file.

• C# script can be inserted anywhere in the aspx page but after the page meta declaration like

  <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Profile.master.cs" Inherits="OOSDDemo.Profile" %>

  <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication3.WebForm1" %> (For WebForm)

\d means a digit in most languages. You can also use [0-9] in all languages. For the "period or comma" use [\.,]. Depending on your language you may need more backslashes based on how you quote the expression. Ultimately, the regular expression engine needs to see a single backslash.

* means "zero-or-more", so \d* and [0-9]* mean "zero or more numbers". ? means "zero-or-one". Neither of those qualifiers means exactly one. Most languages also let you use {m,n} to mean "between m and n" (ie: {1,2} means "between 1 and 2")

Since the dot or comma and additional numbers are optional, you can put them in a group and use the ? quantifier to mean "zero-or-one" of that group.

Putting that all together you can use:

\d{1,2}([\.,][\d{1,2}])?

Meaning, one or two digits \d{1,2}, followed by zero-or-one of a group (...)? consisting of a dot or comma followed by one or two digits [\.,]\d{1,2}

I know this is an old post but I would like to add my answer for future reference. I use jQuery and css to style my tooltips: easiest-tooltip-and-image-preview-using-jquery (for a demo: http://cssglobe.com/lab/tooltip/02/) On my static websites this just worked great. However, during migrating to Wordpress it stopped. My solution was to change tags like <br> and <span> into this: <br> and <span> This works for me.

Be careful, the solution proposed with $a = array_combine($a, $a); will not work for numeric values.

I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384) to be the keys as well as the values however PHP manual states:

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.

So I solved it like this:

foreach($array as $key => $val) {
    $new_array[$val]=$val;
}

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

PHP does not do styling. You need to use html or css. Take a look at http://www.w3schools.com/tags/tag_hr.asp

In HTML 4.01, the

In HTML 4.01, the <hr> tag represents a horizontal rule.

You can use a for loop:

for (i in 1:nrow(df)) {
   df$col3[i] <- df$col1[i] + df$col2[i]
}

The following is my understanding var reading answer above and google.

Where is it pushed on?

esp - 4. More precisely:

• esp gets subtracted by 4
• the value is pushed to esp

pop reverses this.

The System V ABI tells Linux to make rsp point to a sensible stack location when the program starts running: What is default register state when program launches (asm, linux)? which is what you should usually use.

How can you push a register?

Minimal GNU GAS example:

.data
    /* .long takes 4 bytes each. */
    val1:
        /* Store bytes 0x 01 00 00 00 here. */
        .long 1
    val2:
        /* 0x 02 00 00 00 */
        .long 2
.text
    /* Make esp point to the address of val2.
     * Unusual, but totally possible. */
    mov $val2, %esp

    /* eax = 3 */
    mov $3, %ea 

    push %eax
    /*
    Outcome:
    - esp == val1
    - val1 == 3
    esp was changed to point to val1,
    and then val1 was modified.
    */

    pop %ebx
    /*
    Outcome:
    - esp == &val2
    - ebx == 3
    Inverses push: ebx gets the value of val1 (first)
    and then esp is increased back to point to val2.
    */

The above on GitHub with runnable assertions.

Why is this needed?

It is true that those instructions could be easily implemented via mov, add and sub.

They reason they exist, is that those combinations of instructions are so frequent, that Intel decided to provide them for us.

The reason why those combinations are so frequent, is that they make it easy to save and restore the values of registers to memory temporarily so they don't get overwritten.

To understand the problem, try compiling some C code by hand.

A major difficulty, is to decide where each variable will be stored.

Ideally, all variables would fit into registers, which is the fastest memory to access (currently about 100x faster than RAM).

But of course, we can easily have more variables than registers, specially for the arguments of nested functions, so the only solution is to write to memory.

We could write to any memory address, but since the local variables and arguments of function calls and returns fit into a nice stack pattern, which prevents memory fragmentation, that is the best way to deal with it. Compare that with the insanity of writing a heap allocator.

Then we let compilers optimize the register allocation for us, since that is NP complete, and one of the hardest parts of writing a compiler. This problem is called register allocation, and it is isomorphic to graph coloring.

When the compiler's allocator is forced to store things in memory instead of just registers, that is known as a spill.

Does this boil down to a single processor instruction or is it more complex?

All we know for sure is that Intel documents a push and a pop instruction, so they are one instruction in that sense.

Internally, it could be expanded to multiple microcodes, one to modify esp and one to do the memory IO, and take multiple cycles.

But it is also possible that a single push is faster than an equivalent combination of other instructions, since it is more specific.

This is mostly un(der)documented:

• Peter Cordes mentions that techniques described at http://agner.org/optimize/microarchitecture.pdf suggest that push and pop take one single micro operation.
• Johan mentions that since the Pentium M Intel uses a "stack engine", which stores precomputed esp+regsize and esp-regsize values, allowing push and pop to execute in a single uop. Also mentioned at: https://en.wikipedia.org/wiki/Stack_register
• What is Intel microcode?
• https://security.stackexchange.com/questions/29730/processor-microcode-manipulation-to-change-opcodes
• How many CPU cycles are needed for each assembly instruction?

Perhaps you need a selected range in addition to cursor position. Here is a simple function, you don't even need jQuery:

function caretPosition(input) {
    var start = input[0].selectionStart,
        end = input[0].selectionEnd,
        diff = end - start;

    if (start >= 0 && start == end) {
        // do cursor position actions, example:
        console.log('Cursor Position: ' + start);
    } else if (start >= 0) {
        // do ranged select actions, example:
        console.log('Cursor Position: ' + start + ' to ' + end + ' (' + diff + ' selected chars)');
    }
}

Let's say you wanna call it on an input whenever it changes or mouse moves cursor position (in this case we are using jQuery .on()). For performance reasons, it may be a good idea to add setTimeout() or something like Underscores _debounce() if events are pouring in:

$('input[type="text"]').on('keyup mouseup mouseleave', function() {
    caretPosition($(this));
});

Here is a fiddle if you wanna try it out: https://jsfiddle.net/Dhaupin/91189tq7/

instead you could easily do it this way :

  $myVar = "hello";
?>
   document.write("<?php echo $myVar ?>");
</script>
</body>

def fig2img ( fig ): """ @brief Convert a Matplotlib figure to a PIL Image in RGBA format and return it @param fig a matplotlib figure @return a Python Imaging Library ( PIL ) image """ # put the figure pixmap into a numpy array buf = fig2data ( fig ) w, h, d = buf.shape return Image.frombytes( "RGBA", ( w ,h ), buf.tostring( ) )

def fig2data ( fig ): """ @brief Convert a Matplotlib figure to a 4D numpy array with RGBA channels and return it @param fig a matplotlib figure @return a numpy 3D array of RGBA values """ # draw the renderer fig.canvas.draw ( )

# Get the RGBA buffer from the figure
w,h = fig.canvas.get_width_height()
buf = np.fromstring ( fig.canvas.tostring_argb(), dtype=np.uint8 )
buf.shape = ( w, h, 4 )

# canvas.tostring_argb give pixmap in ARGB mode. Roll the ALPHA channel to have it in RGBA mode
buf = np.roll ( buf, 3, axis = 2 )
return buf

def rgba2rgb(img, c=(0, 0, 0), path='foo.jpg', is_already_saved=False, if_load=True): if not is_already_saved: background = Image.new("RGB", img.size, c) background.paste(img, mask=img.split()[3]) # 3 is the alpha channel

    background.save(path, 'JPEG', quality=100)   
    is_already_saved = True
if if_load:
    if is_already_saved:
        im = Image.open(path)
        return np.array(im)
    else:
        raise ValueError('No image to load.')

First add Dimension component:

import { AppRegistry, Text, View,Dimensions } from 'react-native';

Second define Variables:

var height = Dimensions.get('window').height;
var width = Dimensions.get('window').width;

Third put it in your stylesheet:

textOutputView: {
    flexDirection:'row',
    paddingTop:20,
    borderWidth:1,
    borderColor:'red',
    height:height*0.25,
    backgroundColor:'darkgrey',
    justifyContent:'flex-end'
}

Actually in this example I wanted to make responsive view and wanted to view only 0.25 of the screen view so I multiplied it with 0.25, if you wanted 100% of the screen don't multiply it with any thing like this:

textOutputView: {
    flexDirection:'row',
    paddingTop:20,
    borderWidth:1,
    borderColor:'red',
    height:height,
    backgroundColor:'darkgrey',
    justifyContent:'flex-end'
}

If you want to include render prop components:

  children: PropTypes.oneOfType([
    PropTypes.arrayOf(PropTypes.node),
    PropTypes.node,
    PropTypes.func
  ])

var appBanners = document.getElementsByClassName('appBanner');

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

JSFiddle.

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

You can use the ps command to take a look at the running containers:

docker ps -a

Let's say you have added a file "xyz.js" under assets/js folder in some Angular project in Visual-Studio, then the easiest way to include that file is to add it to .angular-cli.json

You should be able to use this JS file's functionality in your component or .ts files.

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

Add a method to your page class like this:

public string YesNo(bool active) 
{
  return active ? "Yes" : "No";
}

And then in your TemplateField you Bind using this method:

<%# YesNo(Active) %>

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

$ gdb a.exe                       // gdb a.out in linux
  (gdb) disass main               // note here main is a function
                                  // similary it can be done for other functions

As DOC says, you can pass data to the handler as next:

// say your selector and click handler looks something like this...
$("some selector").on('click',{param1: "Hello", param2: "World"}, cool_function);

// in your function, just grab the event object and go crazy...
function cool_function(event){
    alert(event.data.param1);
    alert(event.data.param2);

    // access element's id where click occur
    alert( event.target.id ); 
}

^{(ansible 2.9.6 ansible-lint 4.2.0)}

See ansible-lint default rules. The condition below causes E602 Don’t compare to empty string

    when: test_myscript.stderr != ""

Correct syntax and also "Ansible Galaxy Warning-Free" option is

    when: test_myscript.stderr | length > 0

Quoting from source code

"Use when: var|length > 0 rather than when: var != "" (or ' 'conversely when: var|length == 0 rather than when: var == "")"

Notes

1. Test empty bare variable e.g.

    - debug:
        msg: "Empty string '{{ var }}' evaluates to False"
      when: not var
      vars:
        var: ''

    - debug:
        msg: "Empty list {{ var }} evaluates to False"
      when: not var
      vars:
        var: []

give

    "msg": "Empty string '' evaluates to False"
    "msg": "Empty list [] evaluates to False"

2. But, testing non-empty bare variable string depends on CONDITIONAL_BARE_VARS. Setting ANSIBLE_CONDITIONAL_BARE_VARS=false the condition works fine but setting ANSIBLE_CONDITIONAL_BARE_VARS=true the condition will fail

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var
      vars:
        var: 'abc'

gives

fatal: [localhost]: FAILED! => 
  msg: |-
    The conditional check 'var' failed. The error was: error while 
    evaluating conditional (var): 'abc' is undefined

Explicit cast to Boolean prevents the error but evaluates to False i.e. will be always skipped (unless var='True'). When the filter bool is used the options ANSIBLE_CONDITIONAL_BARE_VARS=true and ANSIBLE_CONDITIONAL_BARE_VARS=false have no effect

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var|bool
      vars:
        var: 'abc'

gives

skipping: [localhost]

3. Quoting from Porting guide 2.8 Bare variables in conditionals

  - include_tasks: teardown.yml
    when: teardown

  - include_tasks: provision.yml
    when: not teardown

" based on a variable you define as a string (with quotation marks around it):"

• In Ansible 2.7 and earlier, the two conditions above evaluated as True and False respectively if teardown: 'true'

• In Ansible 2.7 and earlier, both conditions evaluated as False if teardown: 'false'

• In Ansible 2.8 and later, you have the option of disabling conditional bare variables, so when: teardown always evaluates as True and when: not teardown always evaluates as False when teardown is a non-empty string (including 'true' or 'false')

4. Quoting from CONDITIONAL_BARE_VARS

"Expect that this setting eventually will be deprecated after 2.12"

iOS 9.2.1, Xcode 7.2.1, ARC enabled

You can always append the '%' by itself without any other format specifiers in the string you are appending, like so...

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [stringTest stringByAppendingString:@"%"];
NSLog(@"%@", stringTest);

For iOS7.0+

To expand the answer to other characters that might cause you conflict you may choose to use:

- (NSString *)stringByAddingPercentEncodingWithAllowedCharacters:(NSCharacterSet *)allowedCharacters

Written out step by step it looks like this:

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [[stringTest stringByAppendingString:@"%"] 
             stringByAddingPercentEncodingWithAllowedCharacters:
             [NSCharacterSet alphanumericCharacterSet]];
stringTest = [stringTest stringByRemovingPercentEncoding];

NSLog(@"percent value of test: %@", stringTest);

Or short hand:

NSLog(@"percent value of test: %@", [[[[NSString stringWithFormat:@"%d", test] 
stringByAppendingString:@"%"] stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]] stringByRemovingPercentEncoding]);

Okay this is an example for the new embed code for youtube videos.

<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM" frameborder="0" allowFullScreen></iframe>

if you want to autoplay it, at the src="http://www.youtube.com/embed/8v_4O44sfjM" add the ?autoplay=1 parameter

So the code will look like this:

<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM?autoplay=1" frameborder="0" allowFullScreen></iframe>

i tried this on my blog and it works ! Hope this help (:

If $AccountNumber or $Balance is a node-set, then this behavior could easily happen. It's not because and is being treated as or.

For example, if $AccountNumber referred to nodes with the values 12345 and 66 and $Balance referred to nodes with the values 55 and 0, then $AccountNumber != '12345' would be true (because 66 is not equal to 12345) and $Balance != '0' would be true (because 55 is not equal to 0).

I'd suggest trying this instead:

<xsl:when test="not($AccountNumber = '12345' or $Balance = '0')">

$AccountNumber = '12345' or $Balance = '0' will be true any time there is an $AccountNumber with the value 12345 or there is a $Balance with the value 0, and if you apply not() to that, you will get a false result.

Working with VS 2013.
Try the following Tools -> Options -> Debugging -> Output Window -> Module Load Messages -> Off

It will disable the display of modules loaded.

You may need to explain your question a little more.

When you say "redirect", to most people that suggest changing the location of the HTML page:

window.location = url;

When you say "redirect to function" - it doesn't really make sense. You can call a function or you can redirect to another page.
You can even redirect and have a function called when the new page loads.

string json = w.JSON;

var serializer = new JavaScriptSerializer();
serializer.RegisterConverters(new[] { new DynamicJsonConverter() });

DynamicJsonConverter.DynamicJsonObject obj = 
      (DynamicJsonConverter.DynamicJsonObject)serializer.Deserialize(json, typeof(object));

Now obj._Dictionary contains a dictionary. Perfect!

This code must be used in conjunction with Deserialize JSON into C# dynamic object? + make the _dictionary variable from "private readonly" to public in the code there

JSTL 1.2 variation leveraged from BalusC answer

<c:set var="baseURL" value="${pageContext.request.requestURL.substring(0, pageContext.request.requestURL.length() - pageContext.request.requestURI.length())}${pageContext.request.contextPath}/" />

<head>
  <base href="${baseURL}" />

The accepted answer didn't work for me as my page jumped slightly on click, messing up my scroll animation.

I decided to update the entire URL using window.history.replaceState rather than using the window.location.hash method. Thus circumventing the hashChange event fired by the browser.

// Only fire when URL has anchor
$('a[href*="#"]:not([href="#"])').on('click', function(event) {

    // Prevent default anchor handling (which causes the page-jumping)
    event.preventDefault();

    if ( location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname ) {
        var target = $(this.hash);
        target = target.length ? target : $('[name=' + this.hash.slice(1) +']');

        if ( target.length ) {    
            // Smooth scrolling to anchor
            $('html, body').animate({
                scrollTop: target.offset().top
            }, 1000);

            // Update URL
            window.history.replaceState("", document.title, window.location.href.replace(location.hash, "") + this.hash);
        }
    }
});

This will only work for int-digits 0-9, but your question seems to suggest that might be enough.

It works by adding the ASCII value of char '0' to the integer digit.

int i=6;
char c = '0'+i;  // now c is '6'

For example:

'0'+0 = '0'
'0'+1 = '1'
'0'+2 = '2'
'0'+3 = '3'

Edit

It is unclear what you mean, "work for alphabets"? If you want the 5th letter of the alphabet:

int i=5;
char c = 'A'-1 + i; // c is now 'E', the 5th letter.

Note that because in C/Ascii, A is considered the 0th letter of the alphabet, I do a minus-1 to compensate for the normally understood meaning of 5th letter.

Adjust as appropriate for your specific situation.
(and test-test-test! any code you write)

Jokab's answer helped me a lot but in my case I could not push to github until I logged in my github account to my git bash so i ran the following commands

git config credential.helper store

then

git push http://github.com/[user name]/[repo name].git

After the second command a GUI window appeared, I provided my login credentials and it worked for me.

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Whenever I run into this issue with newer browsers, I just use AppRobotic Personal edition to click specific screen coordinates, or tab through the buttons and click.

Basically it's just using its macro functionality, but won't work on headless setups though.

If you know the elements that need mouse events, and if your overlay is transparent, you can just set the z-index of them to something higher than the overlay. All events should of course work in that case on all browsers.

Inspired by jpmottin in this question, here's the one line code:

var dateStr = '2019-01-01';_x000D_
var days = 1;_x000D_
_x000D_
var result = new Date(new Date(dateStr).setDate(new Date(dateStr).getDate() + days));_x000D_
_x000D_
document.write('Date: ', result); // Wed Jan 02 2019 09:00:00 GMT+0900 (Japan Standard Time)_x000D_
document.write('<br />');_x000D_
document.write('Trimmed Date: ', result.toISOString().substr(0, 10)); // 2019-01-02

Hope this helps

Have you had a look at getcwd()?

#include <unistd.h>
char *getcwd(char *buf, size_t size);

Simple example:

#include <unistd.h>
#include <stdio.h>
#include <limits.h>

int main() {
   char cwd[PATH_MAX];
   if (getcwd(cwd, sizeof(cwd)) != NULL) {
       printf("Current working dir: %s\n", cwd);
   } else {
       perror("getcwd() error");
       return 1;
   }
   return 0;
}

If all you need is to ensure uniqueness of elements, then HashSet is what you need.

What do you mean when you say "just a set implementation"? A set is (by definition) a collection of unique elements that doesn't save element order.

The framework creates threads to support each window you create, eg, as when you create a Form and .Show() it. When the windows close, the threads are terminated (ie, they exit).

This is normal behavior. However, if the application is creating threads, and there are a lot of thread exit messages corresponding to these threads (one could tell possibly by the thread's names, by giving them distinct names in the app), then perhaps this is indicative of a problem with the app creating threads when it shouldn't, due to a program logic error.

It would be an interesting followup to have the original poster let us know what s/he discovered regarding the problems with the server crashing. I have a feeling it wouldn't have anything to do with this... but it's hard to tell from the information posted.

There is no rule. I find CTEs more readable, and use them unless they exhibit some performance problem, in which case I investigate the actual problem rather than guess that the CTE is the problem and try to re-write it using a different approach. There is usually more to the issue than the way I chose to declaratively state my intentions with the query.

There are certainly cases when you can unravel CTEs or remove subqueries and replace them with a #temp table and reduce duration. This can be due to various things, such as stale stats, the inability to even get accurate stats (e.g. joining to a table-valued function), parallelism, or even the inability to generate an optimal plan because of the complexity of the query (in which case breaking it up may give the optimizer a fighting chance). But there are also cases where the I/O involved with creating a #temp table can outweigh the other performance aspects that may make a particular plan shape using a CTE less attractive.

Quite honestly, there are way too many variables to provide a "correct" answer to your question. There is no predictable way to know when a query may tip in favor of one approach or another - just know that, in theory, the same semantics for a CTE or a single subquery should execute the exact same. I think your question would be more valuable if you present some cases where this is not true - it may be that you have discovered a limitation in the optimizer (or discovered a known one), or it may be that your queries are not semantically equivalent or that one contains an element that thwarts optimization.

So I would suggest writing the query in a way that seems most natural to you, and only deviate when you discover an actual performance problem the optimizer is having. Personally I rank them CTE, then subquery, with #temp table being a last resort.

Simplest of all solutions:

In Python 3.x:

import urllib.request
url = "https://api.github.com/users?since=100"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
data_content = response.read()
print(data_content)

I suggest using JavaScript's Array method filter() to identify an element by value. It filters data by using a "function to test each element of the array. Return true to keep the element, false otherwise.."

The following function filters the data, returning data for which the callback returns true, i.e. where data.code equals the requested country code.

function getCountryByCode(code) {
  return data.filter(
      function(data){ return data.code == code }
  );
}

var found = getCountryByCode('DZ');

See the demonstration below:

var data = [{_x000D_
  "name": "Afghanistan",_x000D_
  "code": "AF"_x000D_
}, {_x000D_
  "name": "Åland Islands",_x000D_
  "code": "AX"_x000D_
}, {_x000D_
  "name": "Albania",_x000D_
  "code": "AL"_x000D_
}, {_x000D_
  "name": "Algeria",_x000D_
  "code": "DZ"_x000D_
}];_x000D_
_x000D_
_x000D_
function getCountryByCode(code) {_x000D_
  return data.filter(_x000D_
    function(data) {_x000D_
      return data.code == code_x000D_
    }_x000D_
  );_x000D_
}_x000D_
_x000D_
var found = getCountryByCode('DZ');_x000D_
_x000D_
document.getElementById('output').innerHTML = found[0].name;

<div id="output"></div>

Here's a JSFiddle.

Swift 3 class:

import UIKit

class CircleView: UIView {

    override func draw(_ rect: CGRect) {
        guard let context = UIGraphicsGetCurrentContext() else {return}
        
        context.addEllipse(in: rect)
        context.setFillColor(UIColor.blue.cgColor)
        context.fillPath()
    }           
}

I found a not-very-intuitive way to do this by using DUMP()

SELECT DUMP(A.NAME), 
       DUMP(A.surname), 
       DUMP(B.ordernum) 
FROM   customer A 
       JOIN orders B 
         ON A.id = B.id

It will return something like:

'Typ=1 Len=2: 0,48' for each column.

Type=1 means VARCHAR2/NVARCHAR2
Type=2 means NUMBER/FLOAT
Type=12 means DATE, etc.

or this for a simple mapping Oracle Type Code Mappings

First I thank you. # 57ar7up and I will add the following code it helps in finding the return phone number.

function index(){
    // $keyword = "0946664869";
    $sql = "SELECT * FROM phone_find LIMIT 10";
    $result =  $this->GlobalMD->query_global($sql);
    $fb = array();
    foreach($result as $value){
        $keyword = $value['phone'];
        $fb[] = $this->facebook_search($keyword);
    }
    var_dump($fb);

}

function facebook_search($query, $type = 'all'){
    $url = 'http://www.facebook.com/search/'.$type.'/?q='.$query;
    $user_agent = $this->loaduserAgent();

    $c = curl_init();
    curl_setopt_array($c, array(
        CURLOPT_URL             => $url,
        CURLOPT_USERAGENT       => $user_agent,
        CURLOPT_RETURNTRANSFER  => TRUE,
        CURLOPT_FOLLOWLOCATION  => TRUE,
        CURLOPT_SSL_VERIFYPEER  => FALSE
    ));
    $data = curl_exec($c);
    preg_match('/\&#123;&quot;id&quot;:(?P<fbUserId>\d+)\,/', $data, $matches);
    if(isset($matches["fbUserId"]) && $matches["fbUserId"] != ""){
        $fbUserId = $matches["fbUserId"];
        $params = array($query,$fbUserId);
    }else{
        $fbUserId = "";
        $params = array($query,$fbUserId);
    }
    return $params;
}

This is strange behavior and although I am unable to say why this is occurring, I can recommend some options.

First, an observation. If you include the image as Content in VS and copy it to the output directory, your code works. If the image is marked as None in VS and you copy it over, it doesn't work.

Solution 1: FileStream

The BitmapImage object accepts a UriSource or StreamSource as a parameter. Let's use StreamSource instead.

        FileStream stream = new FileStream("picture.png", FileMode.Open, FileAccess.Read);
        Image i = new Image();
        BitmapImage src = new BitmapImage();
        src.BeginInit();
        src.StreamSource = stream;
        src.EndInit();
        i.Source = src;
        i.Stretch = Stretch.Uniform;
        panel.Children.Add(i);

The problem: stream stays open. If you close it at the end of this method, the image will not show up. This means that the file stays write-locked on the system.

Solution 2: MemoryStream

This is basically solution 1 but you read the file into a memory stream and pass that memory stream as the argument.

        MemoryStream ms = new MemoryStream();
        FileStream stream = new FileStream("picture.png", FileMode.Open, FileAccess.Read);
        ms.SetLength(stream.Length);
        stream.Read(ms.GetBuffer(), 0, (int)stream.Length);

        ms.Flush();
        stream.Close();

        Image i = new Image();
        BitmapImage src = new BitmapImage();
        src.BeginInit();
        src.StreamSource = ms;
        src.EndInit();
        i.Source = src;
        i.Stretch = Stretch.Uniform;
        panel.Children.Add(i);

Now you are able to modify the file on the system, if that is something you require.

To add ANDROID_HOME value permanently,

gedit ~/.bashrc

and add the following lines

export ANDROID_HOME=/root/Android/Sdk
PATH=$PATH:$ANDROID_HOME/tools

Save the file and you need not update ANDROID_HOME value everytime.

The Groovy script you provided is formatting the first line as a blank line in the resultant script. The shebang, telling the script to run with /bin/bash instead of /bin/sh, needs to be on the first line of the file or it will be ignored.

So instead, you should format your Groovy like this:

stage('Setting the variables values') {
    steps {
         sh '''#!/bin/bash
                 echo "hello world" 
         '''
    }
}

And it will execute with /bin/bash.

My problem was slightly different: I have anchor tags that define an href, and I want to use ng-disabled to prevent the link from going anywhere when clicked. The solution is to un-set the href when the link is disabled, like this:

<a ng-href="{{isDisabled ? '' : '#/foo'}}"
   ng-disabled="isDisabled">Foo</a>

In this case, ng-disabled is only used for styling the element.

If you want to avoid using unofficial attributes, you'll need to style it yourself:

<style>
a.disabled {
    color: #888;
}
</style>
<a ng-href="{{isDisabled ? '' : '#/foo'}}"
   ng-class="{disabled: isDisabled}">Foo</a>

Your else statement should look like this (note the ^):

{{^avatar}}
 ...
{{/avatar}}

In mustache this is called 'Inverted sections'.

Stumbled upon this one but you can get it by using the following as long as you import numpy.

import numpy as np

[y, x] = np.shape(img[:,:,0])

It works because you ignore all but one color and then the image is just 2D so shape tells you how bid it is. Still kinda new to Python but seems like a simple way to do it.

You can create a link , having get variable in href.

<a href="www.site.com/hello?getVar=value" >...</a>

For those looking to control the space between a dynamic number of columns, try:

<div class="row no-gutters">
    <div class="col">
        <div class="inner">
            <!-- content here -->
        </div>
    </div>
    <div class="col">
        <div class="inner">
            <!-- content here -->
        </div>
    </div>
    <!-- etc. -->
</div>

CSS:

.col:not(:last-child) .inner {
  margin: 2px; // Or whatever you want your spacing to be
}

SELECT LAST(row_name) FROM table_name

You can also use Yapdi:

Basic usage:

import yapdi

daemon = yapdi.Daemon()
retcode = daemon.daemonize()

# This would run in daemon mode; output is not visible
if retcode == yapdi.OPERATION_SUCCESSFUL:
print('Hello Daemon')

I had the same error message. In my case, Jackson consisted of multiple JAR files. Sadly, they had different versions of jackson-core and jackson-annotations which resulted in the above exception.

Maybe you don't have the jackson-annotation JAR in your classpath, at least not in the correct version. You can analyze the used library versions with the command mvn dependency:tree.

For php 5.3+ you can use the SplFileInfo() class

$spl = new SplFileInfo($filename); 
print_r($spl->getExtension()); //gives extension 

Also since you are checking extension for file uploads, I highly recommend using the mime type instead..

For php 5.3+ use the finfo class

$finfo = new finfo(FILEINFO_MIME);
print_r($finfo->buffer(file_get_contents($file name)); 

In the DOM, the class of an element is just each class separated by a space. You would just need to implement the parsing logic to insert / remove the classes as necesary.

I wonder though... why wouldn't you want to use jQuery? It makes this kind of problem trivially easy.

You get a SIGABRT error whenever you have a disconnected outlet. Click on your view controller in the storyboard and go to connections in the side panel (the arrow symbol). See if you have an extra outlet there, a duplicate, or an extra one that's not connected. If it's not that then maybe you haven't connected your outlets to your code correctly.

Just remember that SIGABRT happens when you are trying to call an outlet (button, view, textfield, etc) that isn't there.

If you use Yarn, you can add the .spec.js or .test.js file directly after:

yarn test src/lib/myfile.test.js

This is the part from my package.json file with Jest installed as a local package (removed the relevant parts):

{
...
  "scripts": {
    "test": "jest",
    "testw": "jest --watch",
    "testc": "jest --coverage",
...
  },
  "devDependencies": {
    "jest": "^18.1.0",
    ...
  },

}

This is a start may be :

- hosts: all
  gather_facts: no
  tasks:
    - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5
      register: ps

    - local_action: command echo item
      with_items: ps.stdout_lines

NOTE: Docs regarding ps.stdout_lines are covered here: ('Register Variables' chapter).
