I tried a JMH using the default archetype: I also added an optimized version based on Runemoro's explanation.

@State(Scope.Benchmark)
@Warmup(iterations = 2)
@Fork(1)
@Measurement(iterations = 10)
@OutputTimeUnit(TimeUnit.NANOSECONDS)
//@BenchmarkMode({ Mode.All })
@BenchmarkMode(Mode.AverageTime)
public class MyBenchmark {
  @Param({ "100", "1000", "1000000000" })
  private int size;

  @Benchmark
  public int two_square_i() {
    int n = 0;
    for (int i = 0; i < size; i++) {
      n += 2 * (i * i);
    }
    return n;
  }

  @Benchmark
  public int square_i_two() {
    int n = 0;
    for (int i = 0; i < size; i++) {
      n += i * i;
    }
    return 2*n;
  }

  @Benchmark
  public int two_i_() {
    int n = 0;
    for (int i = 0; i < size; i++) {
      n += 2 * i * i;
    }
    return n;
  }
}

The result are here:

On my PC (Core i7 860 - it is doing nothing much apart from reading on my smartphone):

• n += i*i then n*2 is first
• 2 * (i * i) is second.

The JVM is clearly not optimizing the same way than a human does (based on Runemoro's answer).

Now then, reading bytecode: javap -c -v ./target/classes/org/sample/MyBenchmark.class

• Differences between 2*(i*i) (left) and 2*i*i (right) here: https://www.diffchecker.com/cvSFppWI
• Differences between 2*(i*i) and the optimized version here: https://www.diffchecker.com/I1XFu5dP

I am not expert on bytecode, but we iload_2 before we imul: that's probably where you get the difference: I can suppose that the JVM optimize reading i twice (i is already here, and there is no need to load it again) whilst in the 2*i*i it can't.

There is very little overall difference between GCC 4.8 and clang 3.3 in terms of speed of the resulting binary. In most cases code generated by both compilers performs similarly. Neither of these two compilers dominates the other one.

Benchmarks telling that there is a significant performance gap between GCC and clang are coincidental.

Program performance is affected by the choice of the compiler. If a developer or a group of developers is exclusively using GCC then the program can be expected to run slightly faster with GCC than with clang, and vice versa.

From developer viewpoint, a notable difference between GCC 4.8+ and clang 3.3 is that GCC has the -Og command line option. This option enables optimizations that do not interfere with debugging, so for example it is always possible to get accurate stack traces. The absence of this option in clang makes clang harder to use as an optimizing compiler for some developers.

multiple inserts are faster but it has thredshould. another thrik is disabling constrains checks temprorary make inserts much much faster. It dosn't matter your table has it or not. For example test disabling foreign keys and enjoy the speed:

SET FOREIGN_KEY_CHECKS=0;

offcourse you should turn it back on after inserts by:

SET FOREIGN_KEY_CHECKS=1;

this is common way to inserting huge data. the data integridity may break so you shoud care of that before disabling foreign key checks.

The apache benchmark tool is very basic, and while it will give you a solid idea of some performance, it is a bad idea to only depend on it if you plan to have your site exposed to serious stress in production.

Having said that, here's the most common and simplest parameters:

-c: ("Concurrency"). Indicates how many clients (people/users) will be hitting the site at the same time. While ab runs, there will be -c clients hitting the site. This is what actually decides the amount of stress your site will suffer during the benchmark.

-n: Indicates how many requests are going to be made. This just decides the length of the benchmark. A high -n value with a -c value that your server can support is a good idea to ensure that things don't break under sustained stress: it's not the same to support stress for 5 seconds than for 5 hours.

-k: This does the "KeepAlive" funcionality browsers do by nature. You don't need to pass a value for -k as it it "boolean" (meaning: it indicates that you desire for your test to use the Keep Alive header from HTTP and sustain the connection). Since browsers do this and you're likely to want to simulate the stress and flow that your site will have from browsers, it is recommended you do a benchmark with this.

The final argument is simply the host. By default it will hit http:// protocol if you don't specify it.

ab -k -c 350 -n 20000 example.com/

By issuing the command above, you will be hitting http://example.com/ with 350 simultaneous connections until 20 thousand requests are met. It will be done using the keep alive header.

After the process finishes the 20 thousand requests, you will receive feedback on stats. This will tell you how well the site performed under the stress you put it when using the parameters above.

For finding out how many people the site can handle at the same time, just see if the response times (means, min and max response times, failed requests, etc) are numbers your site can accept (different sites might desire different speeds). You can run the tool with different -c values until you hit the spot where you say "If I increase it, it starts to get failed requests and it breaks".

Depending on your website, you will expect an average number of requests per minute. This varies so much, you won't be able to simulate this with ab. However, think about it this way: If your average user will be hitting 5 requests per minute and the average response time that you find valid is 2 seconds, that means that 10 seconds out of a minute 1 user will be on requests, meaning only 1/6 of the time it will be hitting the site. This also means that if you have 6 users hitting the site with ab simultaneously, you are likely to have 36 users in simulation, even though your concurrency level (-c) is only 6.

This depends on the behavior you expect from your users using the site, but you can get it from "I expect my user to hit X requests per minute and I consider an average response time valid if it is 2 seconds". Then just modify your -c level until you are hitting 2 seconds of average response time (but make sure the max response time and stddev is still valid) and see how big you can make -c.

I hope I explained this clear :) Good luck

#include <iostream>

http://opt.sourceforge.net/ Java Micro Benchmark - control tasks required to determine the comparative performance characteristics of the computer system on different platforms. Can be used to guide optimization decisions and to compare different Java implementations.

It's five oranges faster. Or rather: there can be no (correct) blanket answer. C++ is a statically compiled language (but then, there's profile guided optimization, too), C# runs aided by a JIT compiler. There are so many differences that questions like “how much faster” cannot be answered, not even by giving orders of magnitude.

System.Environment.TickCount and the System.Diagnostics.Stopwatch class are two that work well for finer resolution and straightforward usage.

I have another working example that uses microseconds (UNIX, POSIX, etc).

    #include <sys/time.h>
    typedef unsigned long long timestamp_t;

    static timestamp_t
    get_timestamp ()
    {
      struct timeval now;
      gettimeofday (&now, NULL);
      return  now.tv_usec + (timestamp_t)now.tv_sec * 1000000;
    }

    ...
    timestamp_t t0 = get_timestamp();
    // Process
    timestamp_t t1 = get_timestamp();

    double secs = (t1 - t0) / 1000000.0L;

Here's the file where we coded this:

https://github.com/arhuaco/junkcode/blob/master/emqbit-bench/bench.c

You have to take into account that measuring the time that took a program to execute depends a lot on the load that the machine has in that specific moment.

Knowing that, the way of obtain the current time in C can be achieved in different ways, an easier one is:

#include <time.h>

#define CPU_TIME (getrusage(RUSAGE_SELF,&ruse), ruse.ru_utime.tv_sec + \
  ruse.ru_stime.tv_sec + 1e-6 * \
  (ruse.ru_utime.tv_usec + ruse.ru_stime.tv_usec))

int main(void) {
    time_t start, end;
    double first, second;

    // Save user and CPU start time
    time(&start);
    first = CPU_TIME;

    // Perform operations
    ...

    // Save end time
    time(&end);
    second = CPU_TIME;

    printf("cpu  : %.2f secs\n", second - first); 
    printf("user : %d secs\n", (int)(end - start));
}

Hope it helps.

Regards!

In very simple terms, I like to think about it like this:

• real is the actual amount of time it took to run the command (as if you had timed it with a stopwatch)

• user and sys are how much 'work' the CPU had to do to execute the command. This 'work' is expressed in units of time.

Generally speaking:

• user is how much work the CPU did to run to run the command's code
• sys is how much work the CPU had to do to handle 'system overhead' type tasks (such as allocating memory, file I/O, ect.) in order to support the running command

Since these last two times are counting 'work' done, they don't include time a thread might have spent waiting (such as waiting on another process or for disk I/O to finish).

real, however, is a measure of actual runtime and not 'work', so it does include any time spent waiting.

You can use this in a shell:

wget -r -nH --cut-dirs=7 --reject="index.html*" \
      http://abc.tamu.edu/projects/tzivi/repository/revisions/2/raw/tzivi/

The Parameters are:

-r recursively download

-nH (--no-host-directories) cuts out hostname 

--cut-dirs=X (cuts out X directories)

I know this was asked over 6 years ago now, but just wanted to add my solution, as some of the suggestions above seem horribly complicated, but my solution was actually very simple.

All I had to do was wrap the pool.map() call to a helper function. Passing the class object along with args for the method as a tuple, which looked a bit like this.

def run_in_parallel(args):
    return args[0].method(args[1])

myclass = MyClass()
method_args = [1,2,3,4,5,6]
args_map = [ (myclass, arg) for arg in method_args ]
pool = Pool()
pool.map(run_in_parallel, args_map)

Java 8 now supports BASE64 Encoding and Decoding. You can use the following classes: java.util.Base64, java.util.Base64.Encoder and java.util.Base64.Decoder.

Example usage:

// encode with padding
String encoded = Base64.getEncoder().encodeToString(someByteArray);

// encode without padding
String encoded = Base64.getEncoder().withoutPadding().encodeToString(someByteArray);

// decode a String
byte [] barr = Base64.getDecoder().decode(encoded); 

Try This:

I think that you want something like this.

HTML:

<div id="1">
    My Content 1
</div>

<div id="2" style="display:none;">
    My Dynamic Content

<button id="btnClick">Click me!</button>

jQuery:

$('#btnClick').on('click',function(){
if($('#1').css('display')!='none'){
$('#2').show().siblings('div').hide();
}else if($('#2').css('display')!='none'){
    $('#1').show().siblings('div').hide();
}
});

I am using WebPack, I had same problem Solution=> In your server.js file

const express = require('express');
const app = express();

app.use(express.static(path.resolve(__dirname, '../dist')));
  app.get('*', function (req, res) {
    res.sendFile(path.resolve(__dirname, '../dist/index.html'));
    // res.end();
  });

Why doesn't my application render after refreshing?

You are correct. You did exactly the right thing, checking the query plan rather than trying to second-guess the optimiser. :-)

Try to connect to the repository using command line SVN to see if you get a similar error.

$ svn checkout http://svn.python.org/projects/peps/trunk

If you keep getting the error, it is probably an issue with your proxy server. I have found that I can't check out internet based SVN projects at work because the firewall blocks most HTTP commands. It only allows GET, POST and others necessary for browsing.

Try to check the limits of your SQL database. Maybe you'r exceeding the field limit for this row.

This might be useful for someone who is looking for a different answer. Go to the Gradle Panel and select your module -> Task -> Verification -> Check. This will check the project for errors and will print the log where the error occurs. Most of the time this Kind of error must be a typo present in your XML file of your project

Update March 2017:

URL.searchParams support has officially landed in Chrome 51, but other browsers still require a polyfill.

The official way to work with query parameters is just to add them onto the URL. From the spec, this is an example:

var url = new URL("https://geo.example.org/api"),
    params = {lat:35.696233, long:139.570431}
Object.keys(params).forEach(key => url.searchParams.append(key, params[key]))
fetch(url).then(/* … */)

However, I'm not sure Chrome supports the searchParams property of a URL (at the time of writing) so you might want to either use a third party library or roll-your-own solution.

Update April 2018:

With the use of URLSearchParams constructor you could assign a 2D array or a object and just assign that to the url.search instead of looping over all keys and append them

var url = new URL('https://sl.se')

var params = {lat:35.696233, long:139.570431} // or:
var params = [['lat', '35.696233'], ['long', '139.570431']]

url.search = new URLSearchParams(params).toString();

fetch(url)

Sidenote: URLSearchParams is also available in NodeJS

const { URL, URLSearchParams } = require('url');

I found the original answer of updating the .edmx file work best in my situation. I just wasn't too happy about altering the model every time it was updated from the database. That's why I wrote an additional Text Template file, that is automaticaly invoked when after the model has changed - just like the entities are newly generated. I post it here in this comment. To make it work, make sure you name it like {model name}.something.tt, and store it in the same folder as your .edmx folder. I named it {model name}.NonPkTables.tt. It does not generate a file on its own due to the invalid file extension definition in the second line. Feel free to use.

Use these 4 simple commands

Step 1 : git checkout <branch_name>

This is obvious to go into that branch.

Step 2 : git pull -s recursive -X theirs

Take remote branch changes and replace with their changes if conflict arise. Here if you do git status you will get something like this your branch is ahead of 'origin/master' by 3 commits.

Step 3 : git reset --hard origin/<branch_name>

Step 4 : git fetch

Hard reset your branch.

Enjoy.

MySQL 5.5 on Ubuntu 14.04 required slightly different commands as recommended here. In a nutshell:

sudo /etc/init.d/mysql stop
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
mysql -u root

And then from the MySQL prompt

FLUSH PRIVILEGES;
SET PASSWORD FOR root@'localhost' = PASSWORD('password');
UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';
FLUSH PRIVILEGES;

And the cited source offers an alternate method as well.

I actually prefer to use the display name for the placeholder text majority of the time. Here is an example of using the DisplayName:

  @Html.TextBoxFor(x => x.FirstName, true, null, new { @class = "form-control", placeholder = Html.DisplayNameFor(x => x.FirstName) })

In general you can use pandas rename function here. Given your dataframe you could change to a new name like this. If you had more columns you could also rename those in the dictionary. The 0 is the current name of your column

import pandas as pd    
import numpy as np   
e = np.random.normal(size=100)  
e_dataframe = pd.DataFrame(e)      

e_dataframe.rename(index=str, columns={0:'new_column_name'})

You might just be better of using while loops rather than for loops for this. I translated your code directly from the java code.

str1 = "ababa"
str2 = "aba"
i = 0

while i < len(str1):
  j = 0
  while j < len(str2):
    if not str1[i+j] == str1[j]:
      break
    if j == (len(str2) -1):
      i += len(str2)
    j+=1  
  i+=1

If you are making use of GUIDs this should be nice and easy, if you are looking for an integer ID, you will have to wait for another answer.

SELECT newId() AS ColId, Col1, Col2, Col3 FROM table1

The newId() will generate a new GUID for you that you can use as your automatically generated id column.

ken's answer above did the trick for me. The problem with the accepted answer is that it only works if you have a single modal on the page. If you have multiple modals, you'll need to do it inline in the "open" param while initializing the dialog, not after the fact.

open: function(type,data) { $(this).parent().appendTo("form"); }

If you do what the first accepted answer tells you with multiple modals, you'll only get the last modal on the page working firing postbacks properly, not all of them.

Try this, it worked for me on Google Chrome:

<style media="print" type="text/css">
    .page {
        background-color: white !important;
    }
</style>

In order to not have the Cannot recover key exception, I had to apply the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files to the installation of Java that was running my application. Version 8 of those files can be found here or the latest version should be listed on this page. The download includes a file that explains how to apply the policy files.

Since JDK 8u151 it isn't necessary to add policy files. Instead the JCE jurisdiction policy files are controlled by a Security property called crypto.policy. Setting that to unlimited with allow unlimited cryptography to be used by the JDK. As the release notes linked to above state, it can be set by Security.setProperty() or via the java.security file. The java.security file could also be appended to by adding -Djava.security.properties=my_security.properties to the command to start the program as detailed here.

Since JDK 8u161 unlimited cryptography is enabled by default.

SELECT   col,
         COUNT(dupe_col) AS dupe_cnt
FROM     TABLE
GROUP BY col
HAVING   COUNT(dupe_col) > 1

It's called the null coalescing (??) operator:

myNewValue = myValue ?? new MyValue();

This checks if an element is at least partially in view (vertical dimension):

function inView(element) {
    var box = element.getBoundingClientRect();
    return inViewBox(box);
}

function inViewBox(box) {
    return ((box.bottom < 0) || (box.top > getWindowSize().h)) ? false : true;
}


function getWindowSize() {
    return { w: document.body.offsetWidth || document.documentElement.offsetWidth || window.innerWidth, h: document.body.offsetHeight || document.documentElement.offsetHeight || window.innerHeight}
}

I just wrote a new Join that I like, so I thought I'd re-answer, with it:

public static string Join<T>(this IEnumerable<T> source, string separator)
{
    return string.Join(separator, source.Select(e => e.ToString()).ToArray());
}

One of the cool things about this is that it work with collections that aren't strings, by calling ToString() on the elements. Usage is still the same:

//...

string s = "     1  2    4 5".Split (
    " ".ToCharArray(), 
    StringSplitOptions.RemoveEmptyEntries
    ).Join (" ");

Both approaches aim to register target type in Spring container.

The difference is that @Bean is applicable to methods, whereas @Component is applicable to types.

Therefore when you use @Bean annotation you control instance creation logic in method's body (see example above). With @Component annotation you cannot.

Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3

Basically need to execute:

git checkout master

before modifying any files

then

git commit -am "Updated version number"

after modified files

and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.

Try :

Simple Image upload in codeigniter

Find below code for easy image upload

public function doupload()
     {
        $upload_path="https://localhost/project/profile"  
        $uid='10'; //creare seperate folder for each user 
        $upPath=upload_path."/".$uid;
        if(!file_exists($upPath)) 
        {
                   mkdir($upPath, 0777, true);
        }
        $config = array(
        'upload_path' => $upPath,
        'allowed_types' => "gif|jpg|png|jpeg",
        'overwrite' => TRUE,
        'max_size' => "2048000",

        { 
            $data['imageError'] =  $this->upload->display_errors();

        }
        else
        {
            $imageDetailArray = $this->upload->data();
            $image =  $imageDetailArray['file_name'];
        }

     }

Hope this helps you to upload image

Maybe you could take a look at JFileChooser, which allow you to use native dialogs in one line of code.

item's border color in swift 4.2:

let cell = tableView.dequeueReusableCell(withIdentifier: "Cell_lastOrderId") as! Cell_lastOrder
cell.layer.borderWidth = 1
cell.layer.borderColor = UIColor.white.cgColor
cell.layer.cornerRadius = 10

Had this issue with ES6 and TypeORM while trying to pass .where("order.id IN (:orders)", { orders }), where orders was a comma separated string of numbers. When I converted to a template literal, the problem was resolved.

.where(`order.id IN (${orders})`);

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

I tested as below. Hope it helps.

Integer[] integers1 = new Integer[10];
        System.out.println(integers1.length); //it has length 10 but it is empty. It is not null array
        for (Integer integer : integers1) {
            System.out.println(integer); //prints all 0s
        }

//But if I manually add 0 to any index, now even though array has all 0s elements
//still it is not empty
//        integers1[2] = 0;
        for (Integer integer : integers1) {
            System.out.println(integer); //Still it prints all 0s but it is not empty
            //but that manually added 0 is different
        }

//Even we manually add 0, still we need to treat it as null. This is semantic logic.

        Integer[] integers2 = new Integer[20];
        integers2 = null; //array is nullified
//        integers2[3] = null; //If I had int[] -- because it is priitive -- then I can't write this line. 
        if (integers2 == null) {
            System.out.println("null Array");
        }   

Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).

>>> import datetime
>>> dtnow = datetime.datetime.now();dtutcnow = datetime.datetime.utcnow()
>>> dtnow
datetime.datetime(2010, 8, 4, 9, 33, 9, 890000)
>>> dtutcnow
datetime.datetime(2010, 8, 3, 23, 33, 9, 890000)
>>> delta = dtnow - dtutcnow
>>> delta
datetime.timedelta(0, 36000)
>>> hh,mm = divmod((delta.days * 24*60*60 + delta.seconds + 30) // 60, 60)
>>> hh,mm
(10, 0)
>>> "%s%+02d:%02d" % (dtnow.isoformat(), hh, mm)
'2010-08-04T09:33:09.890000+10:00'
>>>

I would go with Ryan's answer if you really want to do this.

In general on a *nix environment, you always want to err on giving away as little permissions as possible.

9 times out of 10, 755 is the ideal permission for this - as the only user with the ability to modify the files will be the webserver. Change this to 775 with your ftp user in a group if you REALLY need to change this.

Since you're new to php by your own admission, here's a helpful link for improving the security of your upload service: move_uploaded_file

I just had the same issue. Use the flex align to center your elements. You need to use align-items: center instead of align-content: center. This will maintain the aspect ratio, while align-content will not keep the aspect ratio.

You have used some type errors. If you want to set 08/16/2011 to following pattern. It is wrong because,

mm stands for minutes, use MM as it is for Months

DD is wrong, it should be dd which represents Days

Try this to achieve the output you want to get ( Tue Aug 16 "Whatever Time" IST 2011 ),

    String date = "08/16/2011"; //input date as String

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy"); // date pattern

    Date myDate = simpleDateFormat.parse(date); // returns date object 

    System.out.println(myDate); //outputs: Tue Aug 16 00:00:00 IST 2011

Yes, main method can be overloaded. Overloaded main method has to be called from inside the "public static void main(String args[])" as this is the entry point when the class is launched by the JVM. Also overloaded main method can have any qualifier as a normal method have.

While this is not yet valid for Java 7 and below, I believe that we should look to the future and at least recognize the changes to come in new versions such as Java 8.

Namely, this new version brings lambdas and method references to Java (along with new APIs, which are another valid solution to this problem. While they still require an interface no new objects are created, and extra classfiles need not pollute output directories due to different handling by the JVM.

Both flavors(lambda and method reference) require an interface available with a single method whose signature is used:

public interface NewVersionTest{
    String returnAString(Object oIn, String str);
}

Names of methods will not matter from here on. Where a lambda is accepted, a method reference is as well. For example, to use our signature here:

public static void printOutput(NewVersionTest t, Object o, String s){
    System.out.println(t.returnAString(o, s));
}

This is just a simple interface invocation, up until the lambda¹ gets passed:

public static void main(String[] args){
    printOutput( (Object oIn, String sIn) -> {
        System.out.println("Lambda reached!");
        return "lambda return";
    }
    );
}

This will output:

Lambda reached!
lambda return

Method references are similar. Given:

public class HelperClass{
    public static String testOtherSig(Object o, String s){
        return "real static method";
    }
}

and main:

public static void main(String[] args){
    printOutput(HelperClass::testOtherSig);
}

the output would be real static method. Method references can be static, instance, non-static with arbitrary instances, and even constructors. For the constructor something akin to ClassName::new would be used.

¹ This is not considered a lambda by some, as it has side effects. It does illustrate, however, the use of one in a more straightforward-to-visualize fashion.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Your best bet is probably waitForCondition and writing a javascript function that returns true when the map is loaded.

It looks like the files npm uses to edit its config files are not created on a clean install, as npm has a default option for each one. This is why you can still get options with npm config get <option>: having those files only overrides the defaults, it doesn't create the options from scratch.

I had never touched my npm config stuff before today, even though I had had it for months now. None of the files were there yet, such as ~/.npmrc (on a Windows 8.1 machine with Git Bash), yet I could run npm config get <something> and, if it was a correct npm option, it returned a value. When I ran npm config set <option> <value>, the file ~/.npmrc seemed to be created automatically, with the option & its value as the only non-commented-out line.

As for deleting options, it looks like this just sets the value back to the default value, or does nothing if that option was never set or was unset & never reset. Additionally, if that option is the only explicitly set option, it looks like ~/.npmrc is deleted, too, and recreated if you set anything else later.

In your case (assuming it is still the same over a year later), it looks like you never set the proxy option in npm. Therefore, as npm's config help page says, it is set to whatever your http_proxy (case-insensitive) environment variable is. This means there is nothing to delete, unless you want to "delete" your HTTP proxy, although you could set the option or environment variable to something else and hope neither breaks your set-up somehow.

Somewhat similar to your original attempt, but more Pythonic, is to use Python's standard negative-indexing convention to count backwards from the end:

df[df.columns[-1]]

Streams

Prior to Java 8

for (Direction dir : Direction.values()) {
            System.out.println(dir);
}

Java 8

We can also make use of lambda and streams (Tutorial):

Stream.of(Direction.values()).forEachOrdered(System.out::println);

Why forEachOrdered and not forEach with streams ?

The behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept.

Also when working with streams (especially parallel ones) keep in mind the nature of streams. As per the doc:

Stream pipeline results may be nondeterministic or incorrect if the behavioral parameters to the stream operations are stateful. A stateful lambda is one whose result depends on any state which might change during the execution of the stream pipeline.

Set<Integer> seen = Collections.synchronizedSet(new HashSet<>());
stream.parallel().map(e -> { if (seen.add(e)) return 0; else return e; })...

Here, if the mapping operation is performed in parallel, the results for the same input could vary from run to run, due to thread scheduling differences, whereas, with a stateless lambda expression the results would always be the same.

Side-effects in behavioral parameters to stream operations are, in general, discouraged, as they can often lead to unwitting violations of the statelessness requirement, as well as other thread-safety hazards.

Streams may or may not have a defined encounter order. Whether or not a stream has an encounter order depends on the source and the intermediate operations.

This code uses vanilla JavaScript. It creates a new <style> element. It sets the text content of that element to be a string containing the new CSS. And it appends that element directly to the iframe document's head.

Keep in mind, however, that accessing elements of a document loaded from another origin is not permitted (for security reasons) -- contentDocument of the iframe element will evaluate to null when attempted from the browsing context of the page embedding the frame.

var iframe = document.getElementById('the-iframe');
var style = document.createElement('style');
style.textContent =
  'body {' +
  '  background-color: some-color;' +
  '  background-image: some-image;' +
  '}' 
;
iframe.contentDocument.head.appendChild(style);

What about a little trickery like NgModel does with NgForm? You have to register your parent as a provider, then load your parent in the constructor of the child.

That way, you don't have to put [sharedList] on all your children.

// Parent.ts
export var parentProvider = {
    provide: Parent,
    useExisting: forwardRef(function () { return Parent; })
};

@Component({
    moduleId: module.id,
    selector: 'parent',
    template: '<div><ng-content></ng-content></div>',
    providers: [parentProvider]
})
export class Parent {
    @Input()
    public sharedList = [];
}

// Child.ts
@Component({
    moduleId: module.id,
    selector: 'child',
    template: '<div>child</div>'
})
export class Child {
    constructor(private parent: Parent) {
        parent.sharedList.push('Me.');
    }
}

Then your HTML

<parent [sharedList]="myArray">
    <child></child>
    <child></child>
</parent>

You can find more information on the subject in the Angular documentation: https://angular.io/guide/dependency-injection-in-action#find-a-parent-component-by-injection

Set your JAVA_HOME environment variable with the required java version (in your case java 1.5), then in build.xml use executable="${JAVA_HOME}/bin/javac" inside <javac></javac> tag .

example:

<target name="java compiler" description="Compiles the java code">
    <javac executable="${JAVA_HOME}/bin/javac" srcdir="./src" 
        destdir="${build.dir}/classes"> 
    </javac> 
</target>

W3C make it clear, on the specification about Button element

Button may be seen as a generic class for all kind of Buttons with no default behavior.

W3C

<div>—the generic flow container we all know and love. It’s a block-level element with no additional semantic meaning (W3C:Markup, WhatWG)

<section>—a generic document or application section. A normally has a heading (title) and maybe a footer too. It’s a chunk of related content, like a subsection of a long article, a major part of the page (eg the news section on the homepage), or a page in a webapp’s tabbed interface. (W3C:Markup, WhatWG)

My suggestion: div: used lower version( i think 4.01 to still) html element(lot of designers handled that). section: recently comming (html5) html element.

You are doing two mistakes here.
1. calling getMaxValue(),getMinValue() methods before array initialization completes.
2.Not storing return value returned by the getMaxValue(),getMinValue() methods.
So try this code

   for (int i = 0 ; i < array.length; i++ ) 
  {
       int next = input.nextInt();
       // sentineil that will stop loop when 999 is entered
       if (next == 999)
       break;
       array[i] = next;
  }
  // get biggest number
  int maxValue = getMaxValue(array);
  System.out.println(maxValue );

  // get smallest number
  int minValue = getMinValue(array);
  System.out.println(minValue);

Vendor independent version, solely relies on ADO.NET interfaces; 2 ways:

public DataTable Read1<T>(string query) where T : IDbConnection, new()
{
    using (var conn = new T())
    {
        using (var cmd = conn.CreateCommand())
        {
            cmd.CommandText = query;
            cmd.Connection.ConnectionString = _connectionString;
            cmd.Connection.Open();
            var table = new DataTable();
            table.Load(cmd.ExecuteReader());
            return table;
        }
    }
}

public DataTable Read2<S, T>(string query) where S : IDbConnection, new() 
                                           where T : IDbDataAdapter, IDisposable, new()
{
    using (var conn = new S())
    {
        using (var da = new T())
        {
            using (da.SelectCommand = conn.CreateCommand())
            {
                da.SelectCommand.CommandText = query;
                da.SelectCommand.Connection.ConnectionString = _connectionString;
                DataSet ds = new DataSet(); //conn is opened by dataadapter
                da.Fill(ds);
                return ds.Tables[0];
            }
        }
    }
}

I did some performance testing, and the second approach always outperformed the first.

Stopwatch sw = Stopwatch.StartNew();
DataTable dt = null;
for (int i = 0; i < 100; i++)
{
    dt = Read1<MySqlConnection>(query); // ~9800ms
    dt = Read2<MySqlConnection, MySqlDataAdapter>(query); // ~2300ms

    dt = Read1<SQLiteConnection>(query); // ~4000ms
    dt = Read2<SQLiteConnection, SQLiteDataAdapter>(query); // ~2000ms

    dt = Read1<SqlCeConnection>(query); // ~5700ms
    dt = Read2<SqlCeConnection, SqlCeDataAdapter>(query); // ~5700ms

    dt = Read1<SqlConnection>(query); // ~850ms
    dt = Read2<SqlConnection, SqlDataAdapter>(query); // ~600ms

    dt = Read1<VistaDBConnection>(query); // ~3900ms
    dt = Read2<VistaDBConnection, VistaDBDataAdapter>(query); // ~3700ms
}
sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());

Read1 looks better on eyes, but data adapter performs better (not to confuse that one db outperformed the other, the queries were all different). The difference between the two depended on query though. The reason could be that Load requires various constraints to be checked row by row from the documentation when adding rows (its a method on DataTable) while Fill is on DataAdapters which were designed just for that - fast creation of DataTables.

The following method converts all the letters into upper/lower case, depending on their position near a space or other special chars.

public static String capitalizeString(String string) {
  char[] chars = string.toLowerCase().toCharArray();
  boolean found = false;
  for (int i = 0; i < chars.length; i++) {
    if (!found && Character.isLetter(chars[i])) {
      chars[i] = Character.toUpperCase(chars[i]);
      found = true;
    } else if (Character.isWhitespace(chars[i]) || chars[i]=='.' || chars[i]=='\'') { // You can add other chars here
      found = false;
    }
  }
  return String.valueOf(chars);
}

But how do I run this? I tried typing: sudo chkconfig.install which doesn't work.

I'm not sure where you got this package or what it contains; A url of download would be helpful. Without being able to look at the contents of chkconfig.install; I'm surprised to find a unix tool like chkconfig to be bundled in a zip archive, maybe it is still yet to be uncompressed, a tar.gz? but maybe it is a shell script?

I should suggest editing it and seeing what you are executing.

sh chkconfig.install or ./chkconfig.install ; which might work....but my suggestion would be to learn to use update-rc.d as the other answers have suggested but do not speak directly to the question...which is pretty hard to answer without being able to look at the data yourself.

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

input type Button

<input type="button" Id="update" value="Update">

I've successfully posted a form with AJAX in perl. After posting the form, controller returns a JSON response as below

            },
            success: function(res) {
                $('#ProductList').empty('');
                console.log(res);

                for (var i in json) {

                    row.append($('<td id=' + json[i].Id + '>').html(json[i].Id));
                    row.append($('<td id=' + json[i].Name + '>').html(json[i].Name));
                    $('</tr>');
                    $('#ProductList').append(row);
                }
            },
            error: function() {
                alert("did not work");
                location.reload(true);
            }
        });
    });
});

Shortest solution to be assign the window to a typescript variable then call the print method on that, like below

in template file

<button ... (click)="window.print()" ...>Submit</button>

and, in typescript file

window: any;
constructor() {
  this.window = window;
}

According to apple doc:

File-Sharing Support
File-sharing support lets apps make user data files available in iTunes 9.1 and later. An app that declares its support for file sharing makes the contents of its /Documents directory available to the user. The user can then move files in and out of this directory as needed from iTunes. This feature does not allow your app to share files with other apps on the same device; that behavior requires the pasteboard or a document interaction controller object.

To enable file sharing for your app, do the following:

1. Add the UIFileSharingEnabled key to your app’s Info.plist file, and set the value of the key to YES. (The actual key name is "Application supports iTunes file sharing")

2. Put whatever files you want to share in your app’s Documents directory.
   

3. When the device is plugged into the user’s computer, iTunes displays a File Sharing section in the Apps tab of the selected device.
   

4. The user can add files to this directory or move files to the desktop.
   

Apps that support file sharing should be able to recognize when files have been added to the Documents directory and respond appropriately. For example, your app might make the contents of any new files available from its interface. You should never present the user with the list of files in this directory and ask them to decide what to do with those files.

For additional information about the UIFileSharingEnabled key, see Information Property List Key Reference.

Apart from having a Path variable, the directory C:\data\db is mandatory.

Create this and the error shall be solved.

to take output in MySQL you can use if statement SYNTAX:

if(condition,if_true,if_false)

the if_true and if_false can be used to verify and to show output as there is no print statement in the MySQL

throw "I'm Evil"

throw will terminate the further execution & expose message string on catch the error.

try {
  throw "I'm Evil"
  console.log("You'll never reach to me", 123465)
} catch (e) {
  console.log(e); // I'm Evil
}

Console after throw will never be reached cause of termination.

throw new Error("I'm Evil")

throw new Error exposes an error event with two params name & message. It also terminate further execution

try {
  throw new Error("I'm Evil")
  console.log("You'll never reach to me", 123465)
} catch (e) {
  console.log(e.name, e.message); // Error I'm Evil
}

throw Error("I'm Evil")

And just for completeness, this works also, though is not technically the correct way to do it -

try {
  throw Error("I'm Evil")
  console.log("You'll never reach to me", 123465)
} catch (e) {
  console.log(e.name, e.message); // Error I'm Evil
}

console.log(typeof(new Error("hello"))) // object
console.log(typeof(Error)) // function

Best way is,

SELECT to_number(replace(:Str,',','')/100) --into num2 
FROM dual;

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

The simplest way is to use slice. If x is your string variable then x[:-1] will return the string variable without the last character. (BTW, x[-1] is the last character in the string variable) You are looking for

my_file_path = '/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/' my_file_path = my_file_path[:-1]

For more detailed explanations - great documentation at that link. For example: It's easy, you only need to set up two loggers.

import sys
import logging

logger = logging.getLogger('')
logger.setLevel(logging.DEBUG)
fh = logging.FileHandler('my_log_info.log')
sh = logging.StreamHandler(sys.stdout)
formatter = logging.Formatter('[%(asctime)s] %(levelname)s [%(filename)s.%(funcName)s:%(lineno)d] %(message)s', datefmt='%a, %d %b %Y %H:%M:%S')
fh.setFormatter(formatter)
sh.setFormatter(formatter)
logger.addHandler(fh)
logger.addHandler(sh)

def hello_logger():
    logger.info("Hello info")
    logger.critical("Hello critical")
    logger.warning("Hello warning")
    logger.debug("Hello debug")

if __name__ == "__main__":
    print(hello_logger())

Output - terminal:

if __name__ == "__main__":
    hello_logger()

output:

Recommendation:

Complete logger configuration from INI file, which also includes setup for stdout and debug.log:

• handler_file
  • level=WARNING
• handler_screen
  • level=DEBUG

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

For error proofing your commands:

execute [INVOKING-FUNCTION] [COMMAND]

execute () {
    function="${1}"
    command="${2}"
    error=$(eval "${command}" 2>&1 >"/dev/null")

    if [ ${?} -ne 0 ]; then
        echo "${function}: ${error}"
        exit 1
    fi
}

Inspired in Lean manufacturing:

• Make errors impossible by design
• Make steps the smallest
• Finish items one by one
• Make it obvious to anyone

Using sorted(d.items()) isn't enough to get us a stable repr. Some of the values in d could be dictionaries too, and their keys will still come out in an arbitrary order. As long as all the keys are strings, I prefer to use:

json.dumps(d, sort_keys=True)

That said, if the hashes need to be stable across different machines or Python versions, I'm not certain that this is bulletproof. You might want to add the separators and ensure_ascii arguments to protect yourself from any changes to the defaults there. I'd appreciate comments.

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

I just solved this problem :

• Class-based Projections doesn't work with query native(@Query(value = "SELECT ...", nativeQuery = true)) so I recommend to define custom DTO using interface .
• Before using DTO should verify the query syntatically correct or not

This will hide the div after 1 second (1000 milliseconds).

setTimeout(function() {_x000D_
    $('#mydiv').fadeOut('fast');_x000D_
}, 1000); // <-- time in milliseconds

#mydiv{_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background: #000;_x000D_
    color: #fff;_x000D_
    text-align: center;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="mydiv">myDiv</div>

If you just want to hide without fading, use hide().

You won't be able to check if char appears at all in some string without atleast going over the string once using loop / recursion ( the built-in methods like indexOf also use a loop )

If the no. of times you look up if a char is in string x is more way more than the length of the string than I would recommend using a Set data structure as that would be more efficient than simply using indexOf

String s = "abc";

// Build a set so we can check if character exists in constant time O(1)
Set<Character> set = new HashSet<>();
int len = s.length();
for(int i = 0; i < len; i++) set.add(s.charAt(i));

// Now we can check without the need of a loop
// contains method of set doesn't use a loop unlike string's contains method
set.contains('a') // true
set.contains('z') // false

Using set you will be able to check if character exists in a string in constant time O(1) but you will also use additional memory ( Space complexity will be O(n) ).

It is already said in other answers . I did it like placing Spinner inside a CardView and changed the cardBackgroundColor . You could use some other views also and set its background either drawable or color . Thus it doesn't affect Spinner drop down arrow. As the spinner dropdown arrow disappears if we set background to Spinner.

 <androidx.cardview.widget.CardView
        android:id="@+id/cardView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:cardCornerRadius="6dp"
        app:cardBackgroundColor="@color/white">
        
        <Spinner
            android:id="@+id/spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"/>

    </androidx.cardview.widget.CardView>

If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:

public  function scopeLike($query, $field, $value){
        return $query->where($field, 'LIKE', "%$value%");
}

So then you can use this method in such way:

User::like('name', 'Tomas')->get();

Have you tried using the WebClient class?

you should be able to use

string result = "";
using (var client = new WebClient())
{
    client.Headers[HttpRequestHeader.ContentType] = "application/json"; 
    result = client.UploadString(url, "POST", json);
}
Console.WriteLine(result);

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

"datetime" expects the date to be formated like this: YYYY-MM-DD HH:MM:SS

so format your date like that when you are inserting.

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

It happens when you compile your projects on higher version of java(say jdk 1.8) and then run it on a lower version (say jdk 1.7).

If you have JRE-1.7 library in your project path then ,

1.Right click on project

2.Go to Properties

3.Select Project Facets

4.Find Java in rows and then choose version (say 1.7) if using JRE-1.7

5.Click Apply and run your project.

try this:

//a[contains(@prop,'foo')]

that should work for any "a" tags in the document

Use

window.location.hash

Answer for 1.:

You should be able to manually build an expression tree that can be passed into OrderBy using the name as a string. Or you could use reflection as suggested in another answer, which might be less work.

Edit: Here is a working example of building an expression tree manually. (Sorting on X.Value, when only knowing the name "Value" of the property). You could (should) build a generic method for doing it.

using System;
using System.Linq;
using System.Linq.Expressions;

class Program
{
    private static readonly Random rand = new Random();
    static void Main(string[] args)
    {
        var randX = from n in Enumerable.Range(0, 100)
                    select new X { Value = rand.Next(1000) };

        ParameterExpression pe = Expression.Parameter(typeof(X), "value");
        var expression = Expression.Property(pe, "Value");
        var exp = Expression.Lambda<Func<X, int>>(expression, pe).Compile();

        foreach (var n in randX.OrderBy(exp))
            Console.WriteLine(n.Value);
    }

    public class X
    {
        public int Value { get; set; }
    }
}

Building an expression tree requires you to know the particpating types, however. That might or might not be a problem in your usage scenario. If you don't know what type you should be sorting on, it will propably be easier using reflection.

Answer for 2.:

Yes, since Comparer<T>.Default will be used for the comparison, if you do not explicitly define the comparer.

You can get the multiple element by id by identifying what element it is. For example

<div id='id'></div>
<div id='id'></div>
<div id='id'></div>

I assume if you are using jQuery you can select all them all by

$("div#id")

. This will get you array of elements you loop them based on your logic.

rename_column :table, :old_column, :new_column

You'll probably want to create a separate migration to do this. (Rename FixColumnName as you will.):

script/generate migration FixColumnName
# creates  db/migrate/xxxxxxxxxx_fix_column_name.rb

Then edit the migration to do your will:

# db/migrate/xxxxxxxxxx_fix_column_name.rb
class FixColumnName < ActiveRecord::Migration
  def self.up
    rename_column :table_name, :old_column, :new_column
  end

  def self.down
    # rename back if you need or do something else or do nothing
  end
end

For Rails 3.1 use:

While, the up and down methods still apply, Rails 3.1 receives a change method that "knows how to migrate your database and reverse it when the migration is rolled back without the need to write a separate down method".

See "Active Record Migrations" for more information.

rails g migration FixColumnName

class FixColumnName < ActiveRecord::Migration
  def change
    rename_column :table_name, :old_column, :new_column
  end
end

If you happen to have a whole bunch of columns to rename, or something that would have required repeating the table name over and over again:

rename_column :table_name, :old_column1, :new_column1
rename_column :table_name, :old_column2, :new_column2
...

You could use change_table to keep things a little neater:

class FixColumnNames < ActiveRecord::Migration
  def change
    change_table :table_name do |t|
      t.rename :old_column1, :new_column1
      t.rename :old_column2, :new_column2
      ...
    end
  end
end

Then just db:migrate as usual or however you go about your business.

For Rails 4:

While creating a Migration for renaming a column, Rails 4 generates a change method instead of up and down as mentioned in the above section. The generated change method is:

$ > rails g migration ChangeColumnName

which will create a migration file similar to:

class ChangeColumnName < ActiveRecord::Migration
  def change
    rename_column :table_name, :old_column, :new_column
  end
end

You need to install some packages such as Unlocker, GuestOSx, etc.

A slight variation...

new File('/path/to/file').eachLine { line ->
  println line
}

Use

driver.findElement(By.linkText("App Configuration")).click()

Other Approaches will be

JavascriptLibrary jsLib = new JavascriptLibrary(); 
jsLib.callEmbeddedSelenium(selenium, "triggerMouseEventAt", elementToClick,"click", "0,0");

or

((JavascriptExecutor) driver).executeScript("arguments[0].click();", elementToClick);

There is also another way for removing the "debug" banner from the flutter app. Now after new release there is no "debugShowCheckedModeBanner: false," code line in main .dart file. So I think these methods are effective:

1. If you are using VS Code, then install "Dart DevTools" from extensions. After installation, you can easily find "Dart DevTools" text icon at the bottom of the VS Code. When you click on that text icon, a link will be open in google chrome. From that link page, you can easily remove the banner by just tapping on the banner icon as shown in this screenshot.

NOTE:-- Dart DevTools is a dart language debugger extension in VS Code

2. If Dart DevTools is already installed in your VS Code, then you can directly open the google chrome and open this URL = "127.0.0.1: ZZZZZ/?hide=debugger&port=XXXXX"

NOTE:-- In this link replace "XXXXX" by 5 digit port-id (on which your flutter app is running) which will vary whenever you use "flutter run" command and replace "ZZZZZ" by your global(unchangeable) 5 digit debugger-id

NOTE:-- these dart dev tools are only for "Google Chrome Browser"

There is a Hidden helper alongside HiddenFor which lets you set the value.

@Html.Hidden("RequiredProperty", "default")

EDIT Based on the edit you've made to the question, you could do this, but I believe you're moving into territory where it will be cheaper and more effective, in the long run, to fight for making the code change. As has been said, even by yourself, the controller or view model should be setting the default.

This code:

<ul>
@{
        var stacks = new System.Diagnostics.StackTrace().GetFrames();
        foreach (var frame in stacks)
        {
            <li>@frame.GetMethod().Name - @frame.GetMethod().DeclaringType</li>
        }
}
</ul>

Will give output like this:

Execute - ASP._Page_Views_ViewDirectoryX__SubView_cshtml
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
ExecutePageHierarchy - System.Web.Mvc.WebViewPage
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
RenderView - System.Web.Mvc.RazorView
Render - System.Web.Mvc.BuildManagerCompiledView
RenderPartialInternal - System.Web.Mvc.HtmlHelper
RenderPartial - System.Web.Mvc.Html.RenderPartialExtensions
Execute - ASP._Page_Views_ViewDirectoryY__MainView_cshtml

So assuming the MVC framework will always go through the same stack, you can grab var frame = stacks[8]; and use the declaring type to determine who your parent view is, and then use that determination to set (or not) the default value. You could also walk the stack instead of directly grabbing [8] which would be safer but even less efficient.

This is how I solved clickable and Visible links in a TextView (by code)

private void setAsLink(TextView view, String url){
        Pattern pattern = Pattern.compile(url);
        Linkify.addLinks(view, pattern, "http://");
        view.setText(Html.fromHtml("<a href='http://"+url+"'>http://"+url+"</a>"));
    }

Apply lambda function

df['original_category'] = df['original_category'].apply(lambda x:x.lower())

I was not even concentrating, here is how to do it

$DOCDIR = [Environment]::GetFolderPath("MyDocuments")
$TARGETDIR = '$DOCDIR\MatchedLog'
if(!(Test-Path -Path $TARGETDIR )){
    New-Item -ItemType directory -Path $TARGETDIR
}

From http://developer.android.com/reference/android/app/Activity.html

public final void showDialog (int id) Added in API level 1

This method was deprecated in API level 13. Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

Simple version of showDialog(int, Bundle) that does not take any arguments. Simply calls showDialog(int, Bundle) with null arguments.

Why

• A fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.
• Here is a nice discussion Android DialogFragment vs Dialog
• Another nice discussion DialogFragment advantages over AlertDialog

On wildfly 8 and later, go to /bin/standalone.conf and put your JAVA_OPTS there, with all you need.

Just use var = var1 var2 and it will automatically concatenate the vars var1 and var2:

awk '{new_var=$1$2; print new_var}' file

You can put an space in between with:

awk '{new_var=$1" "$2; print new_var}' file

Which in fact is the same as using FS, because it defaults to the space:

awk '{new_var=$1 FS $2; print new_var}' file

Test

$ cat file
hello how are you
i am fine
$ awk '{new_var=$1$2; print new_var}' file
hellohow
iam
$ awk '{new_var=$1 FS $2; print new_var}' file
hello how
i am

This worked form me.. PHP Code on page.php

 $query_de="sql statements here";
 $sql_de = sqlsrv_query($conn,$query_de);
      if ($sql_de)
      {
        echo "SQLSuccess";
       }
         exit();

and then AJAX Code has bellow

jQuery.ajax({
                    url  : "page.php",
                    type : "POST",
                    data : {
                            buttonsave   : 1,
                            var1         : val1,
                            var2         : val2,
                              },
                  success:function(data)
                           {
                     if(jQuery.trim(data) === "SQLSuccess")
                                   {
                           alert("Se agrego correctamente");
                          // alert(data);
                                      } else { alert(data);}
                              },
                   error: function(error)
                           {
                    alert("Error AJAX not working: "+ error );
                              } 
               }); 

NOTE: the word 'SQLSuccess' must be received from PHP

You can use EXCEPT in mssql or MINUS in oracle, they are identical according to :

http://blog.sqlauthority.com/2008/08/07/sql-server-except-clause-in-sql-server-is-similar-to-minus-clause-in-oracle/

CSV Export does not escape your data. Watch out for strings which end in \ because the resulting \" will look like an escaped " and not a \. Then you have the wrong number of " and your entire row is broken.

Here is my example with bash script inside .gitconfig alias section

[alias]
        pushall = "!f(){ for i in `git remote`; do git push $i; done; };f"

I don't have Oracle to test it, but the most efficient solution is to use analytic queries. It should look something like this:

SELECT DISTINCT
    UserId
  , MaxValue
FROM (
    SELECT UserId
      , FIRST (Value) Over (
          PARTITION BY UserId
          ORDER BY Date DESC
        ) MaxValue
    FROM SomeTable
  )

I suspect that you can get rid of the outer query and put distinct on the inner, but I'm not sure. In the meantime I know this one works.

If you want to learn about analytic queries, I'd suggest reading http://www.orafaq.com/node/55 and http://www.akadia.com/services/ora_analytic_functions.html. Here is the short summary.

Under the hood analytic queries sort the whole dataset, then process it sequentially. As you process it you partition the dataset according to certain criteria, and then for each row looks at some window (defaults to the first value in the partition to the current row - that default is also the most efficient) and can compute values using a number of analytic functions (the list of which is very similar to the aggregate functions).

In this case here is what the inner query does. The whole dataset is sorted by UserId then Date DESC. Then it processes it in one pass. For each row you return the UserId and the first Date seen for that UserId (since dates are sorted DESC, that's the max date). This gives you your answer with duplicated rows. Then the outer DISTINCT squashes duplicates.

This is not a particularly spectacular example of analytic queries. For a much bigger win consider taking a table of financial receipts and calculating for each user and receipt, a running total of what they paid. Analytic queries solve that efficiently. Other solutions are less efficient. Which is why they are part of the 2003 SQL standard. (Unfortunately Postgres doesn't have them yet. Grrr...)

You should use the flex or flex-basis property rather than width. Read more on MDN.

.flexbox .red {
  flex: 0 0 25em;
}

The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. It contains:

flex-grow: 0;     /* do not grow   - initial value: 0 */
flex-shrink: 0;   /* do not shrink - initial value: 1 */
flex-basis: 25em; /* width/height  - initial value: auto */

A simple demo shows how to set the first column to 50px fixed width.

.flexbox {_x000D_
  display: flex;_x000D_
}_x000D_
.red {_x000D_
  background: red;_x000D_
  flex: 0 0 50px;_x000D_
}_x000D_
.green {_x000D_
  background: green;_x000D_
  flex: 1;_x000D_
}_x000D_
.blue {_x000D_
  background: blue;_x000D_
  flex: 1;_x000D_
}

<div class="flexbox">_x000D_
  <div class="red">1</div>_x000D_
  <div class="green">2</div>_x000D_
  <div class="blue">3</div>_x000D_
</div>

Mmhh I know you've already discarded URLEncoder, but despite of what the docs say, I decided to give it a try.

You said:

For example, given an input:

http://google.com/resource?key=value

I expect the output:

http%3a%2f%2fgoogle.com%2fresource%3fkey%3dvalue

So:

C:\oreyes\samples\java\URL>type URLEncodeSample.java
import java.net.*;

public class URLEncodeSample {
    public static void main( String [] args ) throws Throwable {
        System.out.println( URLEncoder.encode( args[0], "UTF-8" ));
    }
}

C:\oreyes\samples\java\URL>javac URLEncodeSample.java

C:\oreyes\samples\java\URL>java URLEncodeSample "http://google.com/resource?key=value"
http%3A%2F%2Fgoogle.com%2Fresource%3Fkey%3Dvalue

As expected.

What would be the problem with this?

A cleaner way to handle file open/close and avoid memory leaks:

Prep:

import numpy as np
import h5py

data_to_write = np.random.random(size=(100,20)) # or some such

Write:

with h5py.File('name-of-file.h5', 'w') as hf:
    hf.create_dataset("name-of-dataset",  data=data_to_write)

Read:

with h5py.File('name-of-file.h5', 'r') as hf:
    data = hf['name-of-dataset'][:]

The most common complaint/question I've seen wrt PyInstaller is "my code can't find a data file which I definitely included in the bundle, where is it?", and it isn't easy to see what/where your code is searching because the extracted code is in a temp location and is removed when it exits. Add this bit of code to see what's included in your onefile and where it is, using @Jonathon Reinhart's resource_path()

for root, dirs, files in os.walk(resource_path("")):
    print(root)
    for file in files:
        print( "  ",file)

You can use array_slice function, but do you will use another values? or only the first 5? because if you will use only the first 5 you can use the LIMIT on SQL.

Also this is an example of how to print List of List using advanced for loop:

public static void main(String[] args){
        int[] a={1,3, 7, 8, 3, 9, 2, 4, 10};
        List<List<Integer>> triplets;
        triplets=sumOfThreeNaive(a, 13);
        for (List<Integer> list : triplets){
            for (int triplet: list){
                System.out.print(triplet+" ");
            }
            System.out.println();
        }
    }

Great blog post on the subject

Extracting the Key Hash from .p12 key

1. Open Terminal or Command line and navigate to where your .p12 key is.
2. Type in: “keytool -v -list -keystore mycert.p12 -storetype pkcs12" where mycert.p12 is the filename of your .p12 key.
3. Enter keystore password (the one you used when exported .p12 key). 4 . Copy sha1 fingerprint signature bytes text.
4. The bytes at sha1 fingerprint signature are needed to write the “sha1.bin” file. You can use a hexadecimal editor to paste the bytes you copied. Afterwards, save the file as “sha1.bin”.
5. Open terminal again and type in: “openssl base64 -in sha1.bin -out base64.txt”.
6. The resulting “base64.txt” will contain the Key Hash that is needed for Facebook.

I had the same problem using regex with bash scripting. I used a 2-step solution using pipes with grep -o applying

 '\[(.*?)\]'  

first, then

'\b.*\b'

Obviously not as efficient at the other answers, but an alternative.

There should be a line in your postgresql.conf file that says:

port = 1486

Change that.

The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/

On Windows it is C:\Program Files\PostgreSQL\9.3\data

Don't forget to sudo service postgresql restart for changes to take effect.

I have done something like this to keep it simple:

edit_text.filters = arrayOf(object : InputFilter {
    override fun filter(
        source: CharSequence?,
        start: Int,
        end: Int,
        dest: Spanned?,
        dstart: Int,
        dend: Int
    ): CharSequence? {
        return source?.subSequence(start, end)
            ?.replace(Regex("[^A-Za-z0-9 ]"), "")
    }
})

This way we are replacing all the unwanted characters in the new part of the source string with an empty string.

The edit_text variable is the EditText object we are referring to.

The code is written in kotlin.

• On the server side, just rename the repository with the mv command as usual:

  mv oldName.git newName.git
  

• Then on the client side, change the value of the [remote "origin"] URL into the new one:

  url=example.com/newName.git
  

It worked for me.

Swift 3

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    self.view.endEditing(true)
}

Here is how I solved it for myself. Below is an Entity example with default value for MySQL. However, this also requires the setup of a constructor in your entity, and for you to set the default value there.

Entity\Example:
  type: entity
  table: example
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    label:
      type: string
      columnDefinition: varchar(255) NOT NULL DEFAULT 'default_value' COMMENT 'This is column comment'

The solutions above are completely changed and deprecated. If you want to use CSS modules (assuming you imported css-loaders) and I have been trying to find an answer for this for such a long time and finally did. The default webpack loader is quite different in the new version.

In your webpack, you need to find a part starting with cssRegex and replace it with this;

{
  test: cssRegex,
  exclude: cssModuleRegex,
  use: getStyleLoaders({
      importLoaders: 1,
      modules: true,
      localIdentName: '[name]__[local]__[hash:base64:5]'
  }),
}

The reason to use it is because strcmp

returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal.

=== only returns true or false, it doesn't tell you which is the "greater" string.

ianhanniballake is right. You can get all the functionality of Activity from FragmentActivity. In fact, FragmentActivity has more functionality.

Using FragmentActivity you can easily build tab and swap format. For each tab you can use different Fragment (Fragments are reusable). So for any FragmentActivity you can reuse the same Fragment.

Still you can use Activity for single pages like list down something and edit element of the list in next page.

Also remember to use Activity if you are using android.app.Fragment; use FragmentActivity if you are using android.support.v4.app.Fragment. Never attach a android.support.v4.app.Fragment to an android.app.Activity, as this will cause an exception to be thrown.

I am sure that you have found a solution somewhere over the past 2 years but the following is a solution that works for your requested site

Another nice way of checking, if you have control the SQL, is to add a default value in the query itself for your int column. Then just check for that value.

e.g for an Oracle database, use NVL

SELECT NVL(ID_PARENT, -999) FROM TABLE_NAME;

then check

if (rs.getInt('ID_PARENT') != -999)
{
}

Of course this also is under the assumption that there is a value that wouldn't normally be found in the column.

You can use both YEAR(timestamp) and WEEK(timestamp), and use both of the these expressions in the SELECT and the GROUP BY clause.

Not overly elegant, but functional...

And of course you can combine these two date parts in a single expression as well, i.e. something like

SELECT CONCAT(YEAR(timestamp), '/', WEEK(timestamp)), etc...
FROM ...
WHERE ..
GROUP BY CONCAT(YEAR(timestamp), '/', WEEK(timestamp))

Edit: As Martin points out you can also use the YEARWEEK(mysqldatefield) function, although its output is not as eye friendly as the longer formula above.

Edit 2 [3 1/2 years later!]:
YEARWEEK(mysqldatefield) with the optional second argument (mode) set to either 0 or 2 is probably the best way to aggregate by complete weeks (i.e. including for weeks which straddle over January 1st), if that is what is desired. The YEAR() / WEEK() approach initially proposed in this answer has the effect of splitting the aggregated data for such "straddling" weeks in two: one with the former year, one with the new year.
A clean-cut every year, at the cost of having up to two partial weeks, one at either end, is often desired in accounting etc. and for that the YEAR() / WEEK() approach is better.

Use file_put_contents()

file_put_contents('file.txt', 'bar');
echo file_get_contents('file.txt'); // bar
file_put_contents('file.txt', 'foo');
echo file_get_contents('file.txt'); // foo

Alternatively, if you're stuck with fopen() you can use the w or w+ modes:

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

The accepted answer is a bad idea in general because the manually created make.exe will stick around and can potentially cause unexpected problems. It actually breaks RubyInstaller: https://github.com/oneclick/rubyinstaller2/issues/105

An alternative is installing make via Chocolatey (as pointed out by @Vasantha Ganesh K)

Another alternative is installing MSYS2 from Chocolatey and using make from C:\tools\msys64\usr\bin. If make isn't installed automatically with MSYS2 you need to install it manually via pacman -S make (as pointed out by @Thad Guidry and @Luke).

It's very simple. Git doesn't care about what's the name of its directory. It only cares what's inside. So you can simply do:

# copy the directory into newrepo dir that exists already (else create it)
$ cp -r gitrepo1 newrepo

# remove .git from old repo to delete all history and anything git from it
$ rm -rf gitrepo1/.git

Note that the copy is quite expensive if the repository is large and with a long history. You can avoid it easily too:

# move the directory instead
$ mv gitrepo1 newrepo

# make a copy of the latest version
# Either:
$ mkdir gitrepo1; cp -r newrepo/* gitrepo1/  # doesn't copy .gitignore (and other hidden files)

# Or:
$ git clone --depth 1 newrepo gitrepo1; rm -rf gitrepo1/.git

# Or (look further here: http://stackoverflow.com/q/1209999/912144)
$ git archive --format=tar --remote=<repository URL> HEAD | tar xf -

Once you create newrepo, the destination to put gitrepo1 could be anywhere, even inside newrepo if you want it. It doesn't change the procedure, just the path you are writing gitrepo1 back.

I just do this and call it a day

Model.Id > -1 ? Html.EnumDropDownListFor(m => m.Property, new { disabled = "disabled" }) : Html.EnumDropDownListFor(m => m.Property)

There are two 'must have' plugins for this:

1. sensible - Ctrl-l for nohlsearch and redraw screen.
2. unimpared - [oh, ]oh and coh to control hlsearch.

I did the following to solve the mentioned problem. I got the mentioned problem when I was trying to run the built exe, even I successfully built the exe using pyinstaller. I did this on Windows 10.

1. go to https://pypi.org/project/six/#files
2. download "six-1.14.0.tar.gz (33.9 kB)"
3. unzip it, copy and paste "six.py" into your source directory.
4. import "six" module into your source code (import six)
5. run source script.

Use DateTime.Now.ToString("yyyy-MM-dd h:mm tt");. See this.

Supported in latest chrome, opera and safari, you can do this:

-webkit-clip-path: inset(0 0 0 0 round 100px);
clip-path: inset(0 0 0 0 round 100px);

You should definitely check out the tool http://bennettfeely.com/clippy/!

one can print values using the format method in python. This small example will help take input of two numbers a and b. Print a+b in first line and a-b in second line

print('{:d}\n{:d}'.format(a+b,a-b))

Similarly in the answer we can do

print ("{0}. {1} appears {2} times.".format(22, 'c', 9999))

The python method format() for string is used to specify a string format. So {0},{1},{2} are like array indexes called as positional parameters. Therefore {0} is assigned first value written in format (a+b), {1} is assigned the second value (a-b) and so on. We can also use keyword instead of positional parameter like for example

print("Hi! my name is {name}".format(name="rashi"))

Therefore name here is the keyword and its value is Rashi Hope it helps :)

Try the following:

grep -v -e '^$'

You can use Type.GetType(string), but you'll need to know the full class name including namespace, and if it's not in the current assembly or mscorlib you'll need the assembly name instead. (Ideally, use Assembly.GetType(typeName) instead - I find that easier in terms of getting the assembly reference right!)

For instance:

// "I know String is in the same assembly as Int32..."
Type stringType = typeof(int).Assembly.GetType("System.String");

// "It's in the current assembly"
Type myType = Type.GetType("MyNamespace.MyType");

// "It's in System.Windows.Forms.dll..."
Type formType = Type.GetType ("System.Windows.Forms.Form, " + 
    "System.Windows.Forms, Version=2.0.0.0, Culture=neutral, " + 
    "PublicKeyToken=b77a5c561934e089");

Unfortunately, there's no exit two levels of for statement, but there are a few workarounds to do what you want:

• Goto. In general, using goto is considered to be bad practice (and rightfully so), but using goto solely for a forward jump out of structured control statements is usually considered to be OK, especially if the alternative is to have more complicated code.

  For Each item In itemList
      For Each item1 In itemList1
          If item1.Text = "bla bla bla" Then
              Goto end_of_for
          End If
      Next
  Next
  
  end_of_for:
  

• Dummy outer block

  Do
      For Each item In itemList
          For Each item1 In itemList1
              If item1.Text = "bla bla bla" Then
                  Exit Do
              End If
          Next
      Next
  Loop While False
  

  or

  Try
      For Each item In itemlist
          For Each item1 In itemlist1
              If item1 = "bla bla bla" Then
                  Exit Try
              End If
          Next
      Next
  Finally
  End Try
  

• Separate function: Put the loops inside a separate function, which can be exited with return. This might require you to pass a lot of parameters, though, depending on how many local variables you use inside the loop. An alternative would be to put the block into a multi-line lambda, since this will create a closure over the local variables.

• Boolean variable: This might make your code a bit less readable, depending on how many layers of nested loops you have:

  Dim done = False
  
  For Each item In itemList
      For Each item1 In itemList1
          If item1.Text = "bla bla bla" Then
              done = True
              Exit For
          End If
      Next
      If done Then Exit For
  Next
  

Just catch the submit event and prevent that, then do ajax

$(document).ready(function () {
    $('#myform').on('submit', function(e) {
        e.preventDefault();
        $.ajax({
            url : $(this).attr('action') || window.location.pathname,
            type: "GET",
            data: $(this).serialize(),
            success: function (data) {
                $("#form_output").html(data);
            },
            error: function (jXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });
});

I just got this same error, "cannot open git-upload-pack", in Eclipse with a BitBucket repo trying to do a pull or a push. I resolved it by switching local branches (Team/Switch To) to the master branch and doing a pull, and then switching back to the branch I was working on and pulling again.

It seems when even using a "valid" custom window name (not _blank, etc.) using window.open to launch a new window, there is still issues. It works fine the first time you click the link, but if you click it again (with the first launched window still up) you receive an "Error: No such interface supported" script debug.

For where field not empty this worked for me:

->where('table_name.field_name', '<>', '')

if (dr[dc.ColumnName].GetType().ToString() == "System.DateTime")

I just want to add that if you want to somehow store the encrypted byte array as String and then retrieve it and decrypt it (often for obfuscation of database values) you can use this approach:

import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
public class StrongAES 
{
    public void run() 
    {
        try 
        {
            String text = "Hello World";
            String key = "Bar12345Bar12345"; // 128 bit key
            // Create key and cipher
            Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
            Cipher cipher = Cipher.getInstance("AES");
            // encrypt the text
            cipher.init(Cipher.ENCRYPT_MODE, aesKey);
            byte[] encrypted = cipher.doFinal(text.getBytes());

            StringBuilder sb = new StringBuilder();
            for (byte b: encrypted) {
                sb.append((char)b);
            }

            // the encrypted String
            String enc = sb.toString();
            System.out.println("encrypted:" + enc);

            // now convert the string to byte array
            // for decryption
            byte[] bb = new byte[enc.length()];
            for (int i=0; i<enc.length(); i++) {
                bb[i] = (byte) enc.charAt(i);
            }

            // decrypt the text
            cipher.init(Cipher.DECRYPT_MODE, aesKey);
            String decrypted = new String(cipher.doFinal(bb));
            System.err.println("decrypted:" + decrypted);

        }
        catch(Exception e) 
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) 
    {
        StrongAES app = new StrongAES();
        app.run();
    }
}

This did it for me. in a custom/reusable class. helps alot with the space in b/w the actual text and left view icon/image

func currencyLeftVeiw(image litery: UIImage) {
        self.leftView = UIView(frame: CGRect(x: 10, y: 0, width: 40, height: 40))
        self.leftViewMode = .always
        let leftViewItSelf = UIImageView(frame: CGRect(x: 10, y: 10, width: 20, height: 20))
        leftViewItSelf.image = litery
        leftView?.addSubview(leftViewItSelf)
    }

You need to use val rather than value.

$("#fileinput").val();

update:

I found the terms of use from Google Map:

Section 10.5

No caching or storage. You will not pre-fetch, cache, index, or store any Content to be used outside the Service, except that you may store limited amounts of Content solely for the purpose of improving the performance of your Maps API Implementation due to network latency (and not for the purpose of preventing Google from accurately tracking usage), and only if such storage: is temporary (and in no event more than 30 calendar days); is secure; does not manipulate or aggregate any part of the Content or Service; and does not modify attribution in any way.

It means we can cache for limited time actually

If it's only a tuple of tuples, something like rows=[map(int, row) for row in rows] will do the trick. (There's a list comprehension and a call to map(f, lst), which is equal to [f(a) for a in lst], in there.)

Eval is not what you want to do, in case there's something like __import__("os").unlink("importantsystemfile") in your database for some reason. Always validate your input (if with nothing else, the exception int() will raise if you have bad input).

INNER JOIN: Returns all rows when there is at least one match in BOTH tables

LEFT JOIN: Return all rows from the left table, and the matched rows from the right table

RIGHT JOIN: Return all rows from the right table, and the matched rows from the left table

FULL JOIN: Return all rows when there is a match in ONE of the tables

If you transferred these files through disk or other means, it is likely they were not saved properly.

This approach I use on my site, maybe you will find it helpful. In my opinion, it's the simpliest solution.

AdBlocker blocks specific classes and html elements, by inspecting these selectors of any blocked ads in developer console (they are all listed) you can see which elements will be always blocked.

E.g. just inspect this question page on stackoverflow and you will see bunch of blocked ads.

For example, any element with bottom-ad class is automatically blocked.

1. I created a non-empty div element with bottom-ad class: <div class="bottom-ad" style="width: 1px; height: 1px;">HI</div>
2. After page loads just check if this element is hidden. I used jQuery, but feel free to use javascript: $('.bottom-ad').css('display') == "none" or even better by using $('.bottom-ad').is(':visible')

If value is true, then AdBlocker is active.

Try this: B = A ( : ), or try the reshape function.

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/reshape.html

It appears the problem is that a user created via the method described in the mongo docs does not have permission to connect to the default database (test), even if that user was created with the "userAdminAnyDatabase" and "dbAdminAnyDatabase" roles.

Your selector is missing a . and though you say you want to change the border-color - you're adding and removing a class that sets the background-color

Basic qustion if you are using generics in your base control. If yes:

lets say we have control:

public class MyComboDropDown : ComboDropDownComon<MyType>
{
    public MyComboDropDown() { }
}

MyComboDropDown will not allow to open designer on it and will be not shown in Toolbox. Why? Because base control is not already compiled - when MyComboDropDown is complied. You can modify to this:

public class MyComboDropDown : MyComboDropDownBase
{
    public MyComboDropDown() { }
}

public class MyComboDropDownBase : ComboDropDownComon<MyType>
{

}

Than after rebuild, and reset toolbox it should be able to see MyComboDropDown in designer and also in Toolbox

This error is definite mismatch between the data that is advertised in the HTTP Headers and the data transferred over the wire.

It could come from the following:

1. Server: If a server has a bug with certain modules that changes the content but don't update the content-length in the header or just doesn't work properly. It was the case for the Node HTTP Proxy at some point (see here)

2. Proxy: Any proxy between you and your server could be modifying the request and not update the content-length header.

As far as I know, I haven't see those problem in IIS but mostly with custom written code.

Let me know if that helps.

Given $arrService = Get-Service -Name $ServiceName, $arrService.Status is a static property, corresponding to the value at the time of the call. Use $arrService.Refresh() when needed to renew the properties to current values.

MSDN ~ ServiceController.Refresh()

Refreshes property values by resetting the properties to their current values.

surprise to see that no have given this syntax.

.each syntax with data or collection

jQuery.each(collection, callback(indexInArray, valueOfElement));

OR

jQuery.each( jQuery('#list option'), function(indexInArray, valueOfElement){
//your code here
}); 

<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;

?>

The answer from skaffman is definitely the correct answer. All logger methods such as error(), warn(), info(), debug() take Throwable as a second parameter:

try {
...
 } catch (Exception e) {
logger.error("error: ", e);
}

However, you can extract stacktrace as a String as well. Sometimes it could be useful if you wish to take advantage of formatting feature using "{}" placeholder - see method void info(String var1, Object... var2); In this case say you have a stacktrace as String, then you can actually do something like this:

try {
...
 } catch (Exception e) {
String stacktrace = TextUtils.getStacktrace(e);
logger.error("error occurred for usename {} and group {}, details: {}",username, group, stacktrace);
}

This will print parametrized message and the stacktrace at the end the same way it does for method: logger.error("error: ", e);

I actually wrote an open source library that has a Utility for extraction of a stacktrace as a String with an option to smartly filter out some noise out of stacktrace. I.e. if you specify the package prefix that you are interested in your extracted stacktrace would be filtered out of some irrelevant parts and leave you with very consized info. Here is the link to the article that explains what utilities the library has and where to get it (both as maven artifacts and git sources) and how to use it as well. Open Source Java library with stack trace filtering, Silent String parsing Unicode converter and Version comparison See the paragraph "Stacktrace noise filter"

for those who have a logic to be implemented inside the RecyclerView adapter you can still use @ernesto approach combined with an on scrollListener to get what you want as the RecyclerView is consulted. Inside the adapter you will have something like this:

@Override
    public void onAttachedToRecyclerView(@NonNull RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);
        RecyclerView.LayoutManager manager = recyclerView.getLayoutManager();
        if(manager instanceof LinearLayoutManager && getItemCount() > 0) {
            LinearLayoutManager llm = (LinearLayoutManager) manager;
            recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                    super.onScrollStateChanged(recyclerView, newState);
                }

                @Override
                public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                    super.onScrolled(recyclerView, dx, dy);
                        int visiblePosition = llm.findFirstCompletelyVisibleItemPosition();
                        if(visiblePosition > -1) {
                            View v = llm.findViewByPosition(visiblePosition);
                            //do something
                            v.setBackgroundColor(Color.parseColor("#777777"));
                        }
                }
            });
        }
    }

This can also be done through the SSMS GUI.

1. Put your table in design view (Right click on table in object explorer->Design)
2. Add a column to the table (or click on the column you want to update if it already exists)
3. In Column Properties, enter (getdate()) in Default Value or Binding field as pictured below

You can use Async - Await:

async function axiosTest() {
  const response = await axios.get(url);
  const data = await response.json();  
}

You can redirect the output of a cmd prompt to a file using > or >> to append to a file.

i.e.

echo Hello World >C:\output.txt
echo Hello again! >>C:\output.txt

or

mybatchfile.bat >C:\output.txt

Note that using > will automatically overwrite the file if it already exists.

You also have the option of redirecting stdin, stdout and stderr.

See here for a complete list of options.

In addition to Dee Jee solution, After trying out his solution, My error never went.

I noticed(after two days of head scratch) that the browser has cached the files improperly.

• My browser wasn't able to load the preview of the cached files and status code from express was 301.
• In the networks tab of the browser dev tools, I get that those files are server from disk cache.

Solution

Remove the cached files. By clearing the browser history in a span of 1 hour, so that all the cached files get deleted.

I really like StartExplorer but it is a contextual launcher rather than in - IDE shell so not sure if that is what you want

if self.table:
    print 'It is not empty'

Is fine too

You can combine multiple conditions to avoid the situation:

CASE WHEN condition1 = true AND condition2 = true THEN calculation1 
     WHEN condition1 = true AND condition2 = false 
     ELSE 'what so ever' END,

Yes. See Named and Optional Arguments. Note that the default value needs to be a constant, so this is OK:

public string Foo(string myParam = "default value") // constant, OK
{
}

but this is not:

public void Bar(string myParam = Foo()) // not a constant, not OK
{
}

pandas dataframe plot will return the ax for you, And then you can start to manipulate the axes whatever you want.

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.randn(100,5))

# you get ax from here
ax = df.plot()
type(ax)  # matplotlib.axes._subplots.AxesSubplot

# manipulate
vals = ax.get_yticks()
ax.set_yticklabels(['{:,.2%}'.format(x) for x in vals])

You'll need to tell your vnc client to export the correct $DISPLAY once you have logged in. How you do that will probably depend on your vnc client.

In Xcode 6+ and iOS8+ you can do the simple steps below

1. Paste .app file on desktop.

2. Open terminal and paste the commands below:

   cd desktop

   xcrun simctl install booted xyz.app

3. Open iPhone simulator and click on app and use

For versions below iOS 8, do the following simple steps.

Note: You'll want to make sure that your app is built for all architectures, the Simulator is x386 in the Build Settings and Build Active Architecture Only set to No.

1. Path: Library->Application Support->iPhone Simulator->7.1 (or another version if you need it)->Applications
2. Create a new folder with the name of the app
3. Go inside the folder and place the .app file here.

Use the strpos function: http://php.net/manual/en/function.strpos.php

$haystack = "foo bar baz";
$needle   = "bar";

if( strpos( $haystack, $needle ) !== false) {
    echo "\"bar\" exists in the haystack variable";
}

In your case:

if( strpos( $a, 'some text' ) !== false ) echo 'text';

Note that my use of the !== operator (instead of != false or == true or even just if( strpos( ... ) ) {) is because of the "truthy"/"falsy" nature of PHP's handling of the return value of strpos.

As of PHP 8.0.0 you can now use str_contains

<?php
    if (str_contains('abc', '')) {
        echo "Checking the existence of the empty string will always 
        return true";
    }

Using ! on the IPython console within spyder allows you to use pip. So, in the example, you could do:

[1] !pip install pymorph

Note, this is also available (though perhaps unreliably) on the Python console for Spyder versions before ~2.3.3. Thanks to @CarlosCordoba for this clarification.

When your program is waiting for I/O (ie. a disk read/write or network read/write etc), the CPU is free to do other tasks even if your program is stopped. The speed of your program will mostly depend on how fast that IO can happen, and if you want to speed it up you will need to speed up the I/O.

If your program is running lots of program instructions and not waiting for I/O, then it is said to be CPU bound. Speeding up the CPU will make the program run faster.

In either case, the key to speeding up the program might not be to speed up the hardware, but to optimize the program to reduce the amount of IO or CPU it needs, or to have it do I/O while it also does CPU intensive stuff.

Create a view and return it as a partial view:

public class AssetsController : Controller
{
    protected void SetMIME(string mimeType)
    {
        this.Response.AddHeader("Content-Type", mimeType);
        this.Response.ContentType = mimeType;
    }

    // this will render a view as a Javascript file
    public ActionResult GlobalJS()
    {
        this.SetMIME("text/javascript");
        return PartialView();
    }
}

Then in the GlobalJS view add the javascript code like (adding the // will make visual studio intellisense read it as java-script)

//<script>

    $(document).ready(function () {
       alert('@ViewBag.PropertyName');
    }); 

//</script>

Then in your final view you can add a reference to the javascript just like this.

<script src="@Url.Action("GlobalJS", "Assets")"></script> 

Then in your final view controller you can create/pass your ViewBags and it will be rendered in your javascript.

public class MyFinalViewController : Controller
{
    public ActionResult Index()
    {
        ViewBag.PropertyName = "My ViewBag value!";
        return View();
    }
}

Hope it helps.

You could simply execute event.stopPropagation on click event of the links themselves. Something like this.

    $(".dropdown-menu a").click((event) => {
         event.stopPropagation()
         let url = event.target.href
         //Do something with the url or any other logic you wish
    })

Edit: If someone saw this answer and is using react, it will not work. React handle the javascript events differently and by the time your react event handler is being called, the event has already been fired and propagated. To overcome that you should attach the event manually like that

handleMenuClick(event) {
   event.stopPropagation()
   let menu_item = event.target
   //implement your logic here.
}
componentDidMount() {
    document.getElementsByClassName("dropdown-menu")[0].addEventListener(
        "click", this.handleMenuClick.bind(this), false)
   }
}

And if someone think it could help. Here is @Daniel Vérité's function, with another param that accept names of columns that can be used in search. This way it decrease the time of processing. At least in my test it reduced a lot.

CREATE OR REPLACE FUNCTION search_columns(
    needle text,
    haystack_columns name[] default '{}',
    haystack_tables name[] default '{}',
    haystack_schema name[] default '{public}'
)
RETURNS table(schemaname text, tablename text, columnname text, rowctid text)
AS $$
begin
  FOR schemaname,tablename,columnname IN
      SELECT c.table_schema,c.table_name,c.column_name
      FROM information_schema.columns c
      JOIN information_schema.tables t ON
        (t.table_name=c.table_name AND t.table_schema=c.table_schema)
      WHERE (c.table_name=ANY(haystack_tables) OR haystack_tables='{}')
        AND c.table_schema=ANY(haystack_schema)
        AND (c.column_name=ANY(haystack_columns) OR haystack_columns='{}')
        AND t.table_type='BASE TABLE'
  LOOP
    EXECUTE format('SELECT ctid FROM %I.%I WHERE cast(%I as text)=%L',
       schemaname,
       tablename,
       columnname,
       needle
    ) INTO rowctid;
    IF rowctid is not null THEN
      RETURN NEXT;
    END IF;
 END LOOP;
END;
$$ language plpgsql;

Bellow is an example of usage of the search_function created above.

SELECT * FROM search_columns('86192700'
    , array(SELECT DISTINCT a.column_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public'
    )

    , array(SELECT b.table_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public')
);

I had same problem. There are two ways to solve this issue.

Preserve subscription

You can manually clear each FormArray element by calling the removeAt(i) function in a loop.

clearFormArray = (formArray: FormArray) => {
  while (formArray.length !== 0) {
    formArray.removeAt(0)
  }
}

The advantage to this approach is that any subscriptions on your formArray, such as that registered with formArray.valueChanges, will not be lost.

See the FormArray documentation for more information.

Cleaner method (but breaks subscription references)

You can replace whole FormArray with a new one.

clearFormArray = (formArray: FormArray) => {
  formArray = this.formBuilder.array([]);
}

This approach causes an issue if you're subscribed to the formArray.valueChanges observable! If you replace the FromArray with a new array, you will lose the reference to the observable that you're subscribed to.

you can configure IIS in IIS Mgr to use EVERY port between 1 and 65535 as long it is not used by any other application

Worksheets("Sheet1").Delete
Worksheets("Sheet2").Delete

Exporting each variable from your variables file. Then importing them with * as in your other file and exporting the as a constant from that file will give you a dynamic object with the named exports from the first file being attributes on the object exported from the second.

Variables.js

export const var1 = 'first';
export const var2 = 'second':
...
export const varN = 'nth';

Other.js

import * as vars from './Variables';

export const Variables = vars;

Third.js

import { Variables } from './Other';

Variables.var2 === 'second'

I only put this in for completeness. I've learned plenty from marius and mdml. Here are the edge weights. Sorry about the arrows. Looks like I'm not the only one saying it can't be helped. I couldn't render this with ipython notebook I had to go straight from python which was the problem with getting my edge weights in sooner.

import networkx as nx
import numpy as np
import matplotlib.pyplot as plt
import pylab

G = nx.DiGraph()

G.add_edges_from([('A', 'B'),('C','D'),('G','D')], weight=1)
G.add_edges_from([('D','A'),('D','E'),('B','D'),('D','E')], weight=2)
G.add_edges_from([('B','C'),('E','F')], weight=3)
G.add_edges_from([('C','F')], weight=4)


val_map = {'A': 1.0,
                   'D': 0.5714285714285714,
                              'H': 0.0}

values = [val_map.get(node, 0.45) for node in G.nodes()]
edge_labels=dict([((u,v,),d['weight'])
                 for u,v,d in G.edges(data=True)])
red_edges = [('C','D'),('D','A')]
edge_colors = ['black' if not edge in red_edges else 'red' for edge in G.edges()]

pos=nx.spring_layout(G)
nx.draw_networkx_edge_labels(G,pos,edge_labels=edge_labels)
nx.draw(G,pos, node_color = values, node_size=1500,edge_color=edge_colors,edge_cmap=plt.cm.Reds)
pylab.show()

I think you should casting variable or use Integer class by call out method doubleValue().

Middleware is a general term for software that serves to "glue together" separate, often complex and already existing, programs. Some software components that are frequently connected with middleware include enterprise applications and Web services.

The best way to help memory to be freed is to nullify large objects:

Sub Whatever()
    Dim someLargeObject as SomeObject

    'expensive computation

    Set someLargeObject = Nothing
End Sub

Also note that global variables remain allocated from one call to another, so if you don't need persistence you should either not use global variables or nullify them when you don't need them any longer.

However this won't help if:

• you need the object after the procedure (obviously)
• your object does not fit in memory

Another possibility is to switch to a 64 bit version of Excel which should be able to use more RAM before crashing (32 bits versions are typically limited at around 1.3GB).

This solution worked for me

1) Click the "Export" tab for the database

2) Click the "Custom" radio button

3) Go the section titled "Format-specific options" and change the dropdown for "Database system or older MySQL server to maximize output compatibility with:" from NONE to MYSQL40.

4) Scroll to the bottom and click "GO".

I resolved the problem trimming the file name to 204 characters (extension included).

The best form is this

$('#example option').length

I wrote a method for this sometime back. It deletes the specified directory and returns true if the directory deletion was successful.

/**
 * Delets a dir recursively deleting anything inside it.
 * @param dir The dir to delete
 * @return true if the dir was successfully deleted
 */
public static boolean deleteDirectory(File dir) {
    if(! dir.exists() || !dir.isDirectory())    {
        return false;
    }

    String[] files = dir.list();
    for(int i = 0, len = files.length; i < len; i++)    {
        File f = new File(dir, files[i]);
        if(f.isDirectory()) {
            deleteDirectory(f);
        }else   {
            f.delete();
        }
    }
    return dir.delete();
}

I solved this issue by setting the global variables as a static properties on the classes to which they are most relevant. In ES5 it looks like this:

var Foo = function(){...};
Foo.globalVar = {};

There is this trick which was shared with me (don't ask for details - won't be able to provide them, but it works for me):

switch (variable_1)
{
    case var value when value == variable_2: // that's the trick
        DoSomething();
        break;
    default:
        DoSomethingElse();
        break;
}

Make the area with your data and formulas a Table:

Then adding new information in the next line will copy all formulas in that table for the new line. Data validation will also be applied for the new row as it was for the whole column. This is indeed Excel being smarter with your data.

NO VBA required...

In Java, there are no multi-dimension arrays. There are arrays of arrays. So:

int[][] array = new int[2][3];

It actually consists of two arrays, each has three elements.

If your byte array may contain runs of ASCII characters that you'd like to be able to see, you might prefer BAIS (Byte Array In String) format instead of Base64. The nice thing about BAIS is that if all the bytes happen to be ASCII, they are converted 1-to-1 to a string (e.g. byte array {65,66,67} becomes simply "ABC") Also, BAIS often gives you a smaller file size than Base64 (this isn't guaranteed).

After converting the byte array to a BAIS string, write it to JSON like you would any other string.

Here is a Java class (ported from the original C#) that converts byte arrays to string and back.

import java.io.*;
import java.lang.*;
import java.util.*;

On MSDN, the documentation for Task.Run Method (Action) provides this example which shows how to run a method asynchronously from main:

using System;
using System.Threading;
using System.Threading.Tasks;

public class Example
{
    public static void Main()
    {
        ShowThreadInfo("Application");

        var t = Task.Run(() => ShowThreadInfo("Task") );
        t.Wait();
    }

    static void ShowThreadInfo(String s)
    {
        Console.WriteLine("{0} Thread ID: {1}",
                          s, Thread.CurrentThread.ManagedThreadId);
    }
}
// The example displays the following output:
//       Application thread ID: 1
//       Task thread ID: 3

Note this statement that follows the example:

The examples show that the asynchronous task executes on a different thread than the main application thread.

So, if instead you want the task to run on the main application thread, see the answer by @StephenCleary.

And regarding the thread on which the task runs, also note Stephen's comment on his answer:

You can use a simple Wait or Result, and there's nothing wrong with that. But be aware that there are two important differences: 1) all async continuations run on the thread pool rather than the main thread, and 2) any exceptions are wrapped in an AggregateException.

(See Exception Handling (Task Parallel Library) for how to incorporate exception handling to deal with an AggregateException.)

Finally, on MSDN from the documentation for Task.Delay Method (TimeSpan), this example shows how to run an asynchronous task that returns a value:

using System;
using System.Threading.Tasks;

public class Example
{
    public static void Main()
    {
        var t = Task.Run(async delegate
                {
                    await Task.Delay(TimeSpan.FromSeconds(1.5));
                    return 42;
                });
        t.Wait();
        Console.WriteLine("Task t Status: {0}, Result: {1}",
                          t.Status, t.Result);
    }
}
// The example displays the following output:
//        Task t Status: RanToCompletion, Result: 42

Note that instead of passing a delegate to Task.Run, you can instead pass a lambda function like this:

var t = Task.Run(async () =>
        {
            await Task.Delay(TimeSpan.FromSeconds(1.5));
            return 42;
        });
