Pure numpy

numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)

Check out the loadtxt documentation.

You can also use python's csv module:

import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")

You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:

result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")

Added Hint:

You could also use pandas.io.parsers.read_csv and get the associated numpy array which can be faster.

hope this might help someone else out there

  SELECT 
.... FROM XXX XX
WHERE

AND(
       param1 IS NULL
       OR XX.param1 = param1
       )

I have the same issue and solved it by reading this post, while solving it, I hitted a problem: auth failed.

And I finally solved it by using a ssh key way to authorize myself. I found the EGit offical guide very useful and I configured the ssh way successfully by refer to the Eclipse SSH Configuration section in the link provided.

Hope it helps.

I would like to avoid using full python directory path in the Notepad++ macro. I tried other solutions given in this page, they failed.

The one working on my PC is:

In Notepad++, press F5.

Copy/paste this:

cmd /k cd /d $(CURRENT_DIRECTORY) && py -3 -i $(FULL_CURRENT_PATH)

Enter.

^https?://

You might have to escape the forward slashes though, depending on context.

The same with me and Windows 7. I ended up adding two lines to eclipse.ini:

-vm 
C:\Program Files\Java\jdk1.6.0_35\bin

I tried using %JAVA_HOME% there, but it did not work.

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

.user is the user settings, and I think .suo is the solution user options. You don't want these files under source control; they will be re-created for each user.

Try the below complete example for the same

<?php
  $objPHPExcel = new PHPExcel();
  $query1 = "SELECT * FROM employee";
  $exec1 = mysql_query($query1) or die ("Error in Query1".mysql_error());
  $serialnumber=0;
  //Set header with temp array
  $tmparray =array("Sr.Number","Employee Login","Employee Name");
  //take new main array and set header array in it.
  $sheet =array($tmparray);

  while ($res1 = mysql_fetch_array($exec1))
  {
    $tmparray =array();
    $serialnumber = $serialnumber + 1;
    array_push($tmparray,$serialnumber);
    $employeelogin = $res1['employeelogin'];
    array_push($tmparray,$employeelogin);
    $employeename = $res1['employeename'];
    array_push($tmparray,$employeename);   
    array_push($sheet,$tmparray);
  }
   header('Content-type: application/vnd.ms-excel');
   header('Content-Disposition: attachment; filename="name.xlsx"');
  $worksheet = $objPHPExcel->getActiveSheet();
  foreach($sheet as $row => $columns) {
    foreach($columns as $column => $data) {
        $worksheet->setCellValueByColumnAndRow($column, $row + 1, $data);
    }
  }

  //make first row bold
  $objPHPExcel->getActiveSheet()->getStyle("A1:I1")->getFont()->setBold(true);
  $objPHPExcel->setActiveSheetIndex(0);
  $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
  $objWriter->save(str_replace('.php', '.xlsx', __FILE__));
?>

I'm a big fan of using EPPlus to perform these types of actions. EPPlus is a library you can reference in your project and easily create/modify spreadsheets on a server. I use it for any project that requires an export function.

Here's a nice blog entry that shows how to use the library, though the library itself should come with some samples that explain how to use it.

Third party libraries are a lot easier to use than Microsoft COM objects, in my opinion. I would suggest giving it a try.

I make all of the solutions in here with no result, so i look in another place and i found a way to trick the IDE, so you have to put a line in the Mainfest to make the Gradle use a different one, the one that you put on build.gradle the line is:

<uses-sdk tools:node="replace" />

just it, and it work.

I hope it helps.

WIth WAMP:

1) you should click on WAMP icon>Put Online (wait till re-started).

2) Then (if you are WiFi on Iphone on same network), open your IP in iPhone browser

i.e. http://192.168.1.22 OR http://164.92.124.42

To find your local IP's:
a) click Start>Run>cmd and type ipconfig ,then you will see there.
OR
b) click the blue arrow and "lease new ip".

p.s. That's all. now you can access (open) localhost from Android or iPhone

If you want the margin-left to work on a span element you'll need to make it display: inline-block or display:block as well.

You could prototype your array to make it more modular, try something like this

    Array.prototype.hasElement = function(element) {
        var i;
        for (i = 0; i < this.length; i++) {
            if (this[i] === element) {
                return i; //Returns element position, so it exists
            }
        }

        return -1; //The element isn't in your array
    };

And you can use it as:

 yourArray.hasElement(yourArrayElement)

Use &

SCSS

.container {
    background:red;
    color:white;

    &.hello {
        padding-left:50px;
    }
}

https://sass-lang.com/documentation/style-rules/parent-selector

You can use lamba function:

index = df.index[lambda x : for x in df.index() ]
print(index)

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

I'm not sure for JPA 1.0 but you can pass a Collection in JPA 2.0:

String qlString = "select item from Item item where item.name IN :names"; 
Query q = em.createQuery(qlString, Item.class);

List<String> names = Arrays.asList("foo", "bar");

q.setParameter("names", names);
List<Item> actual = q.getResultList();

assertNotNull(actual);
assertEquals(2, actual.size());

Tested with EclipseLInk. With Hibernate 3.5.1, you'll need to surround the parameter with parenthesis:

String qlString = "select item from Item item where item.name IN (:names)";

But this is a bug, the JPQL query in the previous sample is valid JPQL. See HHH-5126.

%M2% and %JAVA_HOME% need to be added to a PATH variable in the USER variables, not the SYSTEM variables.

On Mac OSX you can add your private key to the keychain using the command:

ssh-add -K /path/to/private_key

If your private key is stored at ~/.ssh and is named id_rsa:

ssh-add -K ~/.ssh/id_rsa

You will then be prompted for your password, which will be stored in your keychain.

Edit - Handle restart

In order to not have to fill in your password even after a restart add the following to your ssh configuration file (commonly located at ~/.ssh/config)

Host *
  UseKeychain yes
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_rsa

On a Scientific Linux 6.7 system, the man page on rsync says:

--ignore-times          don't skip files that match size and time

I have two files with identical contents, but with different creation dates:

[root@windstorm ~]# ls -ls /tmp/master/usercron /tmp/new/usercron
4 -rwxrwx--- 1 root root 1595 Feb 15 03:45 /tmp/master/usercron
4 -rwxrwx--- 1 root root 1595 Feb 16 04:52 /tmp/new/usercron

[root@windstorm ~]# diff /tmp/master/usercron /tmp/new/usercron
[root@windstorm ~]# md5sum /tmp/master/usercron /tmp/new/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/master/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/new/usercron

With --size-only, the two files are regarded the same:

[root@windstorm ~]# rsync -v --size-only -n  /tmp/new/usercron /tmp/master/usercron

sent 29 bytes  received 12 bytes  82.00 bytes/sec
total size is 1595  speedup is 38.90 (DRY RUN)

With --ignore-times, the two files are regarded different:

[root@windstorm ~]# rsync -v --ignore-times -n  /tmp/new/usercron /tmp/master/usercron
usercron

sent 32 bytes  received 15 bytes  94.00 bytes/sec
total size is 1595  speedup is 33.94 (DRY RUN)

So it does not looks like --ignore-times has any effect at all.

Byterbit solution is problematic because:

1. having the client control expiration of a server side cookie is a security issue.
2. if expiration timeout set on server side is smaller than the timeout set on client side, the page would not reflect the actual state of the cookie.
3. even if for the sake of comfort in development stage, this is a problem because it won't reflect the right behaviour (in timing) on release stage.

for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.

expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.

making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

https://developer.wordpress.org/reference/functions/wp_hash_password/

function calenderEdit(dob) {
    var date= $('#'+dob).val();
    $("#dob").datepicker({
        changeMonth: true,
        changeYear: true, yearRange: '1950:+10'
    }).datepicker("setDate", date);
}

It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.

I like to do something like this:

String oneLetter = "" + someChar;

this query will alter the multiple column test it.

create table test(a int,B int,C int);

alter table test drop(a,B);

if you have number of columns in your database table more than number of columns in your csv you can proceed like this:

LOAD DATA LOCAL INFILE 'pathOfFile.csv'
INTO TABLE youTable 
CHARACTER SET latin1 FIELDS TERMINATED BY ';' #you can use ',' if you have comma separated
OPTIONALLY ENCLOSED BY '"' 
ESCAPED BY '\\' 
LINES TERMINATED BY '\r\n'
(yourcolumn,yourcolumn2,yourcolumn3,yourcolumn4,...);

Use the C# coalesce operator: ??

// if Value is not null, newValue = Value else if Value is null newValue is YournullValue
var newValue = Value ?? YourNullReplacement;

I'm late to the party, but searching for the correct way to do it I came across this page it was one of the top Google search returns, so I will like to share my view on the problem, which I consider it to be up to date at the time of writing this post (beginning of 2017). From PHP 7.1.0 the mcrypt_decrypt and mcrypt_encrypt is going to be deprecated, so building future proof code should use openssl_encrypt and openssl_decrypt

You can do something like:

$string_to_encrypt="Test";
$password="password";
$encrypted_string=openssl_encrypt($string_to_encrypt,"AES-128-ECB",$password);
$decrypted_string=openssl_decrypt($encrypted_string,"AES-128-ECB",$password);

Important: This uses ECB mode, which isn't secure. If you want a simple solution without taking a crash course in cryptography engineering, don't write it yourself, just use a library.

You can use any other chipper methods as well, depending on your security need. To find out the available chipper methods please see the openssl_get_cipher_methods function.

You need to use -I with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach:

INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)

If you want today's date without the time, just use Date.today

I see a lot of complicated answers, while this is super simple in Bootstrap 3:

Step 1: Use the official example code to create your radio button group, and give the container an id:

<div id="myButtons" class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
  </label>
</div>

Step 2: Use this jQuery handler:

$("#myButtons :input").change(function() {
    console.log(this); // points to the clicked input button
});

Try the fiddle demo

If you are using a SpringBoot application it's as simple as

ScheduledProcess

@Log
@Component
public class ScheduledProcess {

    @Scheduled(fixedRate = 5000)
    public void run() {
        log.info("this runs every 5 seconds..");
    }

}

Application.class

@SpringBootApplication
// ADD THIS ANNOTATION TO YOUR APPLICATION CLASS
@EnableScheduling
public class SchedulingTasksApplication {

    public static void main(String[] args) {
        SpringApplication.run(SchedulingTasksApplication.class);
    }
}

Your folder/file structure seems a little odd to me. I can't quite figure out how you've got this laid out.

Hello I am using CodeIgniter for two applications (a public and an admin app).

This sounds to me like you've got two separate CI installations. If this is the case, I'd recommend against it. Why not just handle all admin stuff in an admin controller? If you do want two separate CI installations, make sure they are definitely distinct entities and that the two aren't conflicting with one another. This line:

$system_folder = "../system";
$application_folder = "../application/admin"; (this line exists of course twice)

And the place you said this exists (/admin/index.php...or did you mean /admin/application/config?) has me scratching my head. You have admin/application/admin and a system folder at the top level?

Another way to accomplish this is with the jq "--arg" flag. Using the original example:

#!/bin/sh

#this works ***
projectID=$(cat file.json | jq -r '.resource[] | 
select(.username=="[email protected]") | .id')
echo "$projectID"

[email protected]

# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[] 
| select(.username=="$EMAILID") | .id')
echo "$projectID"

See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626

//if(data="undefined"){

This is an assignment statement, not a comparison. Also, "undefined" is a string, it's a property. Checking it is like this: if (data === undefined) (no quotes, otherwise it's a string value)

If it's not defined, you may be returning an empty string. You could try checking for a falsy value like if (!data) as well

Just to expand on @T.J. Crowder's answer.

json_encode does well with simple html strings, in my experience however json_encode often becomes confused by, (or it becomes quite difficult to properly escape) longer complex nested html mixed with php. Two options to consider if you are in this position are: encoding/decoding the markup first with something like [base64_encode][1]/ decode (quite a bit of a performance hit), or (and perhaps preferably) be more selective in what you are passing via json, and generate the necessary markup on the client side instead.

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

http://docs.scipy.org/doc/numpy/user/basics.indexing.html#boolean-or-mask-index-arrays

I believe this is much simpler;

dynamic obj = JObject.Parse(jsonString);
string results  = obj.results;
foreach(string result in result.Split('))
{
//Todo
}

The following commands rename the branch locally, delete the old branch on the remote location and push the new branch, setting the local branch to track the new remote:

git branch -m old_branch new_branch
git push origin :old_branch
git push --set-upstream origin new_branch

My issue was copying source code to a new machine without pulling over any of the referenced assemblies.

Nothing that I did fixed the error, so in haste, I deleted the BIN directory altogether. Rebuilt my source code, and it worked from then on out.

I found that in the project it was not referencing the Microsoft.VisualStudio.QualityTools.UnitTestFramework assembly. Instead, it was referencing Microsoft.VisualStudio.TestPlatform.TestFramework and Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions. When I removed those two references and added the reference to the Microsoft.VisualStudio.QualityTools.UnitTestFramework assembly the tests that were previously marked with the blue exclamation point suddenly became active and started working.

Here is another answer (and personally I think it's more appropriate)

var currentDate = new Date(); 
currentDate = JSON.stringify(currentDate);

// Now currentDate is in a different format... oh gosh what do we do...

currentDate = new Date(JSON.parse(currentDate));

// Now currentDate is back to its original form :)

i found this posible solution:

public void logout() {
    ExternalContext ctx = FacesContext.getCurrentInstance().getExternalContext();
    String ctxPath = ((ServletContext) ctx.getContext()).getContextPath();
    try {
        //Use the context of JSF for invalidate the session,
        //without servlet
        ((HttpSession) ctx.getSession(false)).invalidate();
        //redirect with JSF context.
        ctx.redirect(ctxPath + "absolute/path/index.jsp");
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

Add two textfields with Save and Cancel actions and read TextFields text data

func alertWithTF() {
    //Step : 1
    let alert = UIAlertController(title: "Great Title", message: "Please input something", preferredStyle: UIAlertController.Style.alert )
    //Step : 2
    let save = UIAlertAction(title: "Save", style: .default) { (alertAction) in
        let textField = alert.textFields![0] as UITextField
        let textField2 = alert.textFields![1] as UITextField
        if textField.text != "" {
            //Read TextFields text data
            print(textField.text!)
            print("TF 1 : \(textField.text!)")
        } else {
            print("TF 1 is Empty...")
        }

        if textField2.text != "" {
            print(textField2.text!)
            print("TF 2 : \(textField2.text!)")
        } else {
            print("TF 2 is Empty...")
        }
    }

    //Step : 3

I prefer the JOIN to join full tables/Views and then use the WHERE To introduce the predicate of the resulting set.

It feels syntactically cleaner.

To align one flex child to the right set it withmargin-left: auto;

From the flex spec:

One use of auto margins in the main axis is to separate flex items into distinct "groups". The following example shows how to use this to reproduce a common UI pattern - a single bar of actions with some aligned on the left and others aligned on the right.

.wrap div:last-child {
  margin-left: auto;
}

Note:

You could achieve a similar effect by setting flex-grow:1 on the middle flex item (or shorthand flex:1) which would push the last item all the way to the right. (Demo)

The obvious difference however is that the middle item becomes bigger than it may need to be. Add a border to the flex items to see the difference.

This is not accurate ---> "...* pass array. arrays are passed by reference. i.e. if you pass array of integers, modified the array inside the method.

Every parameter type is passed by value in Java. Arrays are object, its object reference is passed by value.

This includes an array of primitives (int, double,..) and objects. The integer value is changed by the methodTwo() but it is still the same arr object reference, the methodTwo() cannot add an array element or delete an array element. methodTwo() cannot also, create a new array then set this new array to arr. If you really can pass an array by reference, you can replace that arr with a brand new array of integers.

Every object passed as parameter in Java is passed by value, no exceptions.

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

One option is to make two plots side by side. ggplot2 provides a nice option for this with facet_wrap():

dat <- data.frame(x = c(rnorm(100), rnorm(100, 10, 2))
  , y = c(rnorm(100), rlnorm(100, 9, 2))
  , index = rep(1:2, each = 100)
  )

require(ggplot2)
ggplot(dat, aes(x,y)) + 
geom_point() + 
facet_wrap(~ index, scales = "free_y")

document.getElementById("myh1id").innerHTML = "my text"

For those of us using non-ISO standard date formats, like civilian vernacular 01/01/2001 (mm/dd/YYYY), including time in a 12hour date format with am/pm marks, the following function will return a valid Date object:

function convertDate(date) {

    // # valid js Date and time object format (YYYY-MM-DDTHH:MM:SS)
    var dateTimeParts = date.split(' ');

    // # this assumes time format has NO SPACE between time and am/pm marks.
    if (dateTimeParts[1].indexOf(' ') == -1 && dateTimeParts[2] === undefined) {

        var theTime = dateTimeParts[1];

        // # strip out all except numbers and colon
        var ampm = theTime.replace(/[0-9:]/g, '');

        // # strip out all except letters (for AM/PM)
        var time = theTime.replace(/[[^a-zA-Z]/g, '');

        if (ampm == 'pm') {

            time = time.split(':');

            // # if time is 12:00, don't add 12
            if (time[0] == 12) {
                time = parseInt(time[0]) + ':' + time[1] + ':00';
            } else {
                time = parseInt(time[0]) + 12 + ':' + time[1] + ':00';
            }

        } else { // if AM

            time = time.split(':');

            // # if AM is less than 10 o'clock, add leading zero
            if (time[0] < 10) {
                time = '0' + time[0] + ':' + time[1] + ':00';
            } else {
                time = time[0] + ':' + time[1] + ':00';
            }
        }
    }
    // # create a new date object from only the date part
    var dateObj = new Date(dateTimeParts[0]);

    // # add leading zero to date of the month if less than 10
    var dayOfMonth = (dateObj.getDate() < 10 ? ("0" + dateObj.getDate()) : dateObj.getDate());

    // # parse each date object part and put all parts together
    var yearMoDay = dateObj.getFullYear() + '-' + (dateObj.getMonth() + 1) + '-' + dayOfMonth;

    // # finally combine re-formatted date and re-formatted time!
    var date = new Date(yearMoDay + 'T' + time);

    return date;
}

Usage:

date = convertDate('11/15/2016 2:00pm');

EXEC gokul_proc(1,'GOKUL', :rc);

I believe you are using Bootstrap 3. If so, please try this code, here is the bootply

The question has already been answered but I thought I would also let you know that rather than using the native PHP $_POST I reccomend you use the CodeIgniter input class so your controller code would be

function post_action()
{   
    if($this->input->post('textbox') == "")
    {
        $message = "You can't send empty text";
    }
    else
    {
        $message = $this->input->post('textbox');
    }
    echo $message;
}

You'll have to strncpy str1 into new_string first then.

I got myself addicted to uplink a few months ago. It's not really coding based, more hacking. It's still fun and super geeky.

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

Configuring Identity to your existing project is not hard thing. You must install some NuGet package and do some small configuration.

First install these NuGet packages with Package Manager Console:

PM> Install-Package Microsoft.AspNet.Identity.Owin 
PM> Install-Package Microsoft.AspNet.Identity.EntityFramework
PM> Install-Package Microsoft.Owin.Host.SystemWeb 

Add a user class and with IdentityUser inheritance:

public class AppUser : IdentityUser
{
    //add your custom properties which have not included in IdentityUser before
    public string MyExtraProperty { get; set; }  
}

Do same thing for role:

public class AppRole : IdentityRole
{
    public AppRole() : base() { }
    public AppRole(string name) : base(name) { }
    // extra properties here 
}

Change your DbContext parent from DbContext to IdentityDbContext<AppUser> like this:

public class MyDbContext : IdentityDbContext<AppUser>
{
    // Other part of codes still same 
    // You don't need to add AppUser and AppRole 
    // since automatically added by inheriting form IdentityDbContext<AppUser>
}

If you use the same connection string and enabled migration, EF will create necessary tables for you.

Optionally, you could extend UserManager to add your desired configuration and customization:

public class AppUserManager : UserManager<AppUser>
{
    public AppUserManager(IUserStore<AppUser> store)
        : base(store)
    {
    }

    // this method is called by Owin therefore this is the best place to configure your User Manager
    public static AppUserManager Create(
        IdentityFactoryOptions<AppUserManager> options, IOwinContext context)
    {
        var manager = new AppUserManager(
            new UserStore<AppUser>(context.Get<MyDbContext>()));

        // optionally configure your manager
        // ...

        return manager;
    }
}

Since Identity is based on OWIN you need to configure OWIN too:

Add a class to App_Start folder (or anywhere else if you want). This class is used by OWIN. This will be your startup class.

namespace MyAppNamespace
{
    public class IdentityConfig
    {
        public void Configuration(IAppBuilder app)
        {
            app.CreatePerOwinContext(() => new MyDbContext());
            app.CreatePerOwinContext<AppUserManager>(AppUserManager.Create);
            app.CreatePerOwinContext<RoleManager<AppRole>>((options, context) =>
                new RoleManager<AppRole>(
                    new RoleStore<AppRole>(context.Get<MyDbContext>())));

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Home/Login"),
            });
        }
    }
}

Almost done just add this line of code to your web.config file so OWIN could find your startup class.

<appSettings>
    <!-- other setting here -->
    <add key="owin:AppStartup" value="MyAppNamespace.IdentityConfig" />
</appSettings>

Now in entire project you could use Identity just like any new project had already installed by VS. Consider login action for example

[HttpPost]
public ActionResult Login(LoginViewModel login)
{
    if (ModelState.IsValid)
    {
        var userManager = HttpContext.GetOwinContext().GetUserManager<AppUserManager>();
        var authManager = HttpContext.GetOwinContext().Authentication;

        AppUser user = userManager.Find(login.UserName, login.Password);
        if (user != null)
        {
            var ident = userManager.CreateIdentity(user, 
                DefaultAuthenticationTypes.ApplicationCookie);
            //use the instance that has been created. 
            authManager.SignIn(
                new AuthenticationProperties { IsPersistent = false }, ident);
            return Redirect(login.ReturnUrl ?? Url.Action("Index", "Home"));
        }
    }
    ModelState.AddModelError("", "Invalid username or password");
    return View(login);
}

You could make roles and add to your users:

public ActionResult CreateRole(string roleName)
{
    var roleManager=HttpContext.GetOwinContext().GetUserManager<RoleManager<AppRole>>();

    if (!roleManager.RoleExists(roleName))
        roleManager.Create(new AppRole(roleName));
    // rest of code
} 

You could also add a role to a user, like this:

UserManager.AddToRole(UserManager.FindByName("username").Id, "roleName");

By using Authorize you could guard your actions or controllers:

[Authorize]
public ActionResult MySecretAction() {}

or

[Authorize(Roles = "Admin")]]
public ActionResult MySecretAction() {}

You can also install additional packages and configure them to meet your requirement like Microsoft.Owin.Security.Facebook or whichever you want.

Note: Don't forget to add relevant namespaces to your files:

using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;

Add the following code to a shape:

<gradient
    android:angle="135"
    android:endColor="#FF444444"
    android:centerColor="#FFAAAAAA"
    android:startColor="#FFFFFFFF"/>

ét voila, you've got a (more or less) indented border, with the light source set to left-top. Fiddle with the size of the bitmap (in relation to the size of the imageview, I used a 200dp x 200dp imageview and a bitmap of 196dp x 196dp in the example, with a radius of 14dp for the corners) and the padding to get the best result. Switch end and startcolor for a bevelled effect.

Here's the full code of the shape you see in the image (save it in res/drawable, e.g. border_shape.xml):

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:angle="135"
        android:endColor="#FF444444"
        android:centerColor="#FFAAAAAA"
        android:startColor="#FFFFFFFF"/>
    <padding
        android:top="2dp"
        android:left="2dp"
        android:right="2dp"
        android:bottom="2dp"/>
    <corners
        android:radius="30dp"/>
</shape>

And call it in your imageview like this:

android:scaleType="center"    
android:background="@drawable/border_shape"
android:cropToPadding="true"
android:adjustViewBounds="true"

And here is the code for the bitmap with rounded corners:

Bitmap getRoundedRectBitmap(Bitmap bitmap, float radius) {
    Paint paint = new Paint();
    PorterDuffXfermode pdmode = new PorterDuffXfermode(PorterDuff.Mode.SRC_IN);
    Bitmap bm = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bm);
    Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
    RectF rectF = new RectF(rect);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(0xff424242);
    canvas.drawRoundRect(rectF, radius, radius, paint);
    paint.setXfermode(pdmode);
    canvas.drawBitmap(bitmap, rect, rect, paint);
    return bm;
}

I know this is an old question, but...

I was just noticing my instance of IISExpress wasn't serving woff files, so I wen't searching (Found this) and then found:

http://www.tomasmcguinness.com/2011/07/06/adding-support-for-svg-to-iis-express/

I suppose my install has support for SVG since I haven't had issue with that. But the instructions are trivially modifiable for woff:

• Open a console application with administrator privilages.
• Navigation to the IIS Express directory. This lives under Program Files or Program Files (x86)

• Run the command:

  appcmd set config /section:staticContent /+[fileExtension='woff',mimeType='application/x-woff']

Solved my problem, and I didn't have to mess with some crummy config (like I had to to add support for the PUT and DELETE verbs). Yay!

The question is correctly answered here Center a column using Twitter Bootstrap 3

For odd rows: i.e., col-md-7 or col-large-9 use this

Add col-centered to the column you want centered.

<div class="col-lg-11 col-centered">    

And add this to your stylesheet:

.col-centered{
float: none;
margin: 0 auto;
}

For even rows: i.e., col-md-6 or col-large-10 use this

Simply use bootstrap 3's offset col class. i.e.,

<div class="col-lg-10 col-lg-offset-1">

On windows, you can use PuttyGen to load the private key file, remove the passphrase and then overwrite the existing private key file.

Another alternative

I have two plots side by side and would like to adjust tick labels separately.

The above solutions were close however they were not working out for me. I found my solution from this matplotlib page.

ax.xaxis.set_tick_params(labelsize=20)

This did the trick and was straight to the point. For my use case, it was the plot on the right that needed to be adjusted. For the plot on the left since I was creating new tick labels I was able to adjust the font in the same process as seting the labels.

ie

ax1.set_xticklabels(ax1_x, fontsize=15)
ax1.set_yticklabels(ax1_y, fontsize=15)

thus I used for the right plot,

ax2.xaxis.set_tick_params(labelsize=24)
ax2.yaxis.set_tick_params(labelsize=24)

A minor subtlety... I know... but I hope this helps someone :)

Bonus points if anyone knows how to adjust the font size of the order of magnitude label.

The varStatus references to LoopTagStatus which has a getIndex() method.

So:

<c:forEach var="tableEntity" items='${requestScope.tables}' varStatus="outer">
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="inner">            
        <c:out value="${(outer.index * fn:length(tableEntity.rows)) + inner.index}" />
    </c:forEach>
</c:forEach>

• Failed validation: 403 Forbidden ("The server understood the request, but is refusing to fulfill it"). Contrary to popular opinion, RFC2616 doesn't say "403 is only intended for failed authentication", but "403: I know what you want, but I won't do that". That condition may or may not be due to authentication.
• Trying to add a duplicate: 409 Conflict ("The request could not be completed due to a conflict with the current state of the resource.")

You should definitely give a more detailed explanation in the response headers and/or body (e.g. with a custom header - X-Status-Reason: Validation failed).

No, and your compiler already gave you a comprehensive explanation.

But you could do this:

constexpr char constString[] = "constString";

At runtime, this can be used to construct a std::string when needed.

I'm using the J.S. to fix a sidebar menu. I've tried a lot of solutions with CSS but it's the simplest way to solve it, just add J.S. adding and removing a native BootStrap class: "position-fixed".

The J.S.:

var lateral = false;
function fixar() {

            var element, name, arr;
            element = document.getElementById("minhasidebar");

            if (lateral) {
                element.className = element.className.replace(
                        /\bposition-fixed\b/g, "");
                lateral = false;
            } else {

                name = "position-fixed";
                arr = element.className.split(" ");
                if (arr.indexOf(name) == -1) {
                    element.className += " " + name;
                }
                lateral = true;
            }

        }

The HTML:

Sidebar:

        <nav class="sidebar ">
             <div id="minhasidebar">
                 <ul class="nav nav-pills">

I researched the same thing several months ago looking at dozens of the most popular Android devices. I found that every Android device had one of the following aspect ratios (from most square to most rectangular):

• 4:3
• 3:2
• 8:5
• 5:3
• 16:9

And if you consider portrait devices separate from landscape devices you'll also find the inverse of those ratios (3:4, 2:3, 5:8, 3:5, and 9:16)

TRY THIS:

Cast your VARCHAR value to DATETIME and add -30 for subtraction. Also, In sql-server the format Fri, 14 Nov 2014 23:03:35 GMT was not converted to DATETIME. Try substring for it:

SELECT DATEADD(dd, -30, 
       CAST(SUBSTRING ('Fri, 14 Nov 2014 23:03:35 GMT', 6, 21) 
       AS DATETIME))

Just go to start > type search box uac press enter > you will see 'Change user account control settings' > down the you will see never notify. Click on OK. And you are done.

Here is a solution I came up with for myself. This is ready to run as a command prompt project. You need to clean some stuff if not. Hope this helps. It accepts several input formats like: 1.234.567,89 1,234,567.89 etc

To use alternate credentials for a single operation, use the --username and --password switches for svn.

To clear previously-saved credentials, delete ~/.subversion/auth. You'll be prompted for credentials the next time they're needed.

These settings are saved in the user's home directory, so if you're using a shared account on "this laptop", be careful - if you allow the client to save your credentials, someone can impersonate you. The first option I provided is the better way to go in this case. At least until you stop using shared accounts on computers, which you shouldn't be doing.

To change credentials you need to do:

• rm -rf ~/.subversion/auth
• svn up ( it'll ask you for new username & password )

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

You may try this one

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                textView.setTextAppearance(R.style.Lato_Bold);
            } else {
                textView.setTextAppearance(getActivity(), R.style.Lato_Bold);
            }

If you are using MySQL or MariaDB, the easiest and performant way dump CSV for single table is -

SELECT customer_id, firstname, surname INTO OUTFILE '/exportdata/customers.txt'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM customers;

Now you can use other techniques to repeat this command for multiple tables. See more details here:

I did what BalusC said but it was not enough for me, I had to clean the Tomcat workdirectory : ( Click right on right on Tomcat in the Servers Tab -> Clean Tomcat Work Directory )

Adding processData: false to the $.ajax options will fix this issue.

Try this:

 public class MyVmBase : INotifyPropertyChanged
{
  private ICommand _clickCommand;
   public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler( MyAction));
        }
    }
    
       public void MyAction(object message)
    {
        if(message == null)
        {
            Notify($"Method {message} not defined");
            return;
        }
        switch (message.ToString())
        {
            case "btnAdd":
                {
                    btnAdd_Click();
                    break;
                }

            case "BtnEdit_Click":
                {
                    BtnEdit_Click();
                    break;
                }

            default:
                throw new Exception($"Method {message} not defined");
                break;
        }
    }
}

  public class CommandHandler : ICommand
{
    private Action<object> _action;
    private Func<object, bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action<object> action, Func<object, bool> canExecute)
    {
        if (action == null) throw new ArgumentNullException(nameof(action));
        _action = action;
        _canExecute = canExecute ?? (x => true);
    }
    public CommandHandler(Action<object> action) : this(action, null)
    {
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _action(parameter);
    }
    public void Refresh()
    {
        CommandManager.InvalidateRequerySuggested();
    }
}

And in xaml:

     <Button
    Command="{Binding ClickCommand}"
    CommandParameter="BtnEdit_Click"/>

People run into this error when the Node.js process is still running and they are attempting to start the server again. Try this:

ps aux | grep node

This will print something along the lines of:

user    7668  4.3  1.0  42060 10708 pts/1    Sl+  20:36   0:00 node server
user    7749  0.0  0.0   4384   832 pts/8    S+   20:37   0:00 grep --color=auto node

In this case, the process will be the one with the pid 7668. To kill it and restart the server, run kill -9 7668.

In case if you don't want to use google geocoding API than you can refer to few other Free APIs for the development purpose. for example i used [mapquest] API in order to get the location name.

you can fetch location name easily by implementing this following function

 const fetchLocationName = async (lat,lng) => {
    await fetch(
      'https://www.mapquestapi.com/geocoding/v1/reverse?key=API-Key&location='+lat+'%2C'+lng+'&outFormat=json&thumbMaps=false',
    )
      .then((response) => response.json())
      .then((responseJson) => {
        console.log(
          'ADDRESS GEOCODE is BACK!! => ' + JSON.stringify(responseJson),
        );
      });
  };

Maybe you can create an array like this:

     var myList = new Array();
     myList.push('Hello');
     myList.push('bye');

     for (var i = 0; i < myList .length; i ++ ){
        window.console.log(myList[i]);
     }

<input name="Email" type="text" id="Email" placeholder="enter your question" />

The placeholder attribute specifies a short hint that describes the expected value of an input field (e.g. a sample value or a short description of the expected format).

The short hint is displayed in the input field before the user enters a value.

Note: The placeholder attribute works with the following input types: text, search, url, tel, email, and password.

I think this will help.

I found this...
http://jsfiddle.net/Mottie/xcqpF/1/light/

function rgb2hex(rgb){
    rgb = rgb.match(/^rgba?[\s+]?\([\s+]?(\d+)[\s+]?,[\s+]?(\d+)[\s+]?,[\s+]?(\d+)[\s+]?/i);
    return (rgb && rgb.length === 4) ? "#" +
        ("0" + parseInt(rgb[1],10).toString(16)).slice(-2) +
        ("0" + parseInt(rgb[2],10).toString(16)).slice(-2) +
        ("0" + parseInt(rgb[3],10).toString(16)).slice(-2) : '';
}

My point is that I just want the raw DATETIME string, so I can parse it myself as is.

That makes me think that your "workaround" is not a workaround, but in fact the only way to get the value from the database into your code:

SELECT CAST(add_date AS CHAR) as add_date

By the way, some more notes from the MySQL documentation:

MySQL Constraints on Invalid Data:

Before MySQL 5.0.2, MySQL is forgiving of illegal or improper data values and coerces them to legal values for data entry. In MySQL 5.0.2 and up, that remains the default behavior, but you can change the server SQL mode to select more traditional treatment of bad values such that the server rejects them and aborts the statement in which they occur.

[..]

If you try to store NULL into a column that doesn't take NULL values, an error occurs for single-row INSERT statements. For multiple-row INSERT statements or for INSERT INTO ... SELECT statements, MySQL Server stores the implicit default value for the column data type.

MySQL 5.x Date and Time Types:

MySQL also allows you to store '0000-00-00' as a “dummy date” (if you are not using the NO_ZERO_DATE SQL mode). This is in some cases more convenient (and uses less data and index space) than using NULL values.

[..]

By default, when MySQL encounters a value for a date or time type that is out of range or otherwise illegal for the type (as described at the beginning of this section), it converts the value to the “zero” value for that type.

• pivot and unpivot
• performance tuning

I was able to get rid of my scroll bar on the body of text by removing my max-height attribute of my class.

I've just had the same problem on a CentOS 7 box.

Seems I'd hit selinux. Putting selinux into permissive mode (setenforce permissive) has worked round the problem for now. I'll try and get back with a proper fix.

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

To escape you could just use this from Java 1.5:

Pattern.quote("$test");

You will match exacty the word $test

To disable the errors windows related with certificates you can start Chrome from console and use this option: --ignore-certificate-errors.

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ignore-certificate-errors

You should use it for testing purposes. A more complete list of options is here: http://peter.sh/experiments/chromium-command-line-switches/

The easiest way to send (simulate) KeyStrokes to any window is to use the SendKeys.Send method of .NET Framework.

Checkout this very intuitive MSDN article http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

Particularly for your case, if your browser window is in focus, sending F5 would just involve the following line of code:

SendKeys.Send("{F5}");

I tried to send/add input tag's values into JavaScript variable which worked well for me, here is the code:

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript">
            function changef()
            {
            var ctext=document.getElementById("c").value;

            document.writeln(ctext);
            }

        </script>
    </head>
    <body>
        <input type="text" id="c" onchange="changef"();>

        <button type="button" onclick="changef()">click</button>
    </body> 
</html>

pip has a --no-dependencies switch. You should use that.

For more information, run pip install -h, where you'll see this line:

--no-deps, --no-dependencies
                        Ignore package dependencies

It won't be caught by the second catch block. Each Exception is caught only when inside a try block. You can nest tries though (not that it's a good idea generally):

try {
    doSomething();
} catch (IOException) {
   try {
       doSomething();
   } catch (IOException e) {
       throw new ApplicationException("Failed twice at doSomething" +
       e.toString());
   }          
} catch (Exception e) {
}

This solution allows you to change the name of the downloaded file:

HTML:

<a id="link"></a>

JAVASCRIPT:

  var link = document.getElementById('link');
  link.setAttribute('download', 'MintyPaper.png');
  link.setAttribute('href', canvas.toDataURL("image/png").replace("image/png", "image/octet-stream"));
  link.click();

1.this is my answer for your problem.

.ModalCarrot::before {
content:'';
background: url('blackCarrot.png'); /*url of image*/
height: 16px; /*height of image*/
width: 33px;  /*width of image*/
position: absolute;
}

I'd go with the default arguments, especially since C++ doesn't let you chain constructors (so you end up having to duplicate the initialiser list, and possibly more, for each overload).

That said, there are some gotchas with default arguments, including the fact that constants may be inlined (and thereby become part of your class' binary interface). Another to watch out for is that adding default arguments can turn an explicit multi-argument constructor into an implicit one-argument constructor:

class Vehicle {
public:
  Vehicle(int wheels, std::string name = "Mini");
};

Vehicle x = 5;  // this compiles just fine... did you really want it to?

DTO classes are used to serialize/deserialize data from different sources. When you want to deserialize a object from a source, does not matter what external source it is: service, file, database etc. you may be only want to use some part of that but you want an easy way to deserialize that data to an object. after that you copy that data to the XModel you want to use. A serializer is a beautiful technology to load DTO objects. Why? you only need one function to load (deserialize) the object.

These are the vendor-prefixed properties offered by the relevant rendering engines (-webkit for Chrome, Safari; -moz for Firefox, -o for Opera, -ms for Internet Explorer). Typically they're used to implement new, or proprietary CSS features, prior to final clarification/definition by the W3.

This allows properties to be set specific to each individual browser/rendering engine in order for inconsistencies between implementations to be safely accounted for. The prefixes will, over time, be removed (at least in theory) as the unprefixed, the final version, of the property is implemented in that browser.

To that end it's usually considered good practice to specify the vendor-prefixed version first and then the non-prefixed version, in order that the non-prefixed property will override the vendor-prefixed property-settings once it's implemented; for example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Specifically, to address the CSS in your question, the lines you quote:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;
-moz-column-count: 3;
-moz-column-gap: 10px;
-moz-column-fill: auto;

Specify the column-count, column-gap and column-fill properties for Webkit browsers and Firefox.

There's a kind of hack-tastic way to do it if you have php enabled on your server. Change this line:

url:   'http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml',

to this line:

url: '/path/to/phpscript.php',

and then in the php script (if you have permission to use the file_get_contents() function):

<?php

header('Content-type: application/xml');
echo file_get_contents("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");

?>

Php doesn't seem to mind if that url is from a different origin. Like I said, this is a hacky answer, and I'm sure there's something wrong with it, but it works for me.

Edit: If you want to cache the result in php, here's the php file you would use:

<?php

$cacheName = 'somefile.xml.cache';
// generate the cache version if it doesn't exist or it's too old!
$ageInSeconds = 3600; // one hour
if(!file_exists($cacheName) || filemtime($cacheName) > time() + $ageInSeconds) {
  $contents = file_get_contents('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml');
  file_put_contents($cacheName, $contents);
}

$xml = simplexml_load_file($cacheName);

header('Content-type: application/xml');
echo $xml;

?>

Caching code take from here.

You can just run:

git stash pop

and it will unstash your changes.

If you want to preserve the state of files (staged vs. working), use

git stash apply --index

I have used below code in my SpringBoot application.

MimeMessage message = sender.createMimeMessage();
message.setContent(message, "text/html");
MimeMessageHelper helper = new MimeMessageHelper(message);

helper.setFrom(fromAddress);
helper.setTo(toAddress);
helper.setSubject(mailSubject);
helper.setText(mailText, true);

sender.send(message);

It's not relative to performance...

You set async to false, when you need that ajax request to be completed before the browser passes to other codes:

<script>
    // ...
    $.ajax(... async: false ...); // Hey browser! first complete this request, 
                                  // then go for other codes

    $.ajax(...); // Executed after the completion of the previous async:false request.
</script>

Use serialize and deserialize methods in SerializationUtils from commons-lang.

All the symptoms you describe suggest that you never tell MySQL what time zone to use so it defaults to system's zone. Think about it: if all it has is '2011-03-13 02:49:10', how can it guess that it's a local Tanzanian date?

As far as I know, MySQL doesn't provide any syntax to specify time zone information in dates. You have to change it a per-connection basis; something like:

SET time_zone = 'EAT';

If this doesn't work (to use named zones you need that the server has been configured to do so and it's often not the case) you can use UTC offsets because Tanzania does not observe daylight saving time at the time of writing but of course it isn't the best option:

SET time_zone = '+03:00';

Or, if you want to avoid the use of a global variable you could use the rarely used .Tag property of the userform:

Private Sub CommandButton1_Click()
    Me.CommandButton1.Enabled = False 'Disabling button so user cannot push it
                                      'multiple times
    Me.CommandButton1.caption = "Wait..." 'Jamie's suggestion
    Me.Tag = "Cancel"
End Sub

Private Sub SomeVBASub
    If LCase(UserForm1.Tag) = "cancel" Then
        GoTo StopProcess
    Else
        'DoStuff
    End If

Exit Sub
StopProcess:
    'Here you can do some steps to be able to cancel process adequately
    'i.e. setting collections to "Nothing" deleting some files...
End Sub

In my Windows case the listener would not start, and 'lsnrctl start' would hang forever. The solution was to kill all processes of extproc. I suspect it had something funny to do with my vpn

To redirect your logs output to a file, you need to use the FileAppender and need to define other file details in your log4j.properties/xml file. Here is a sample properties file for the same:

# Root logger option
log4j.rootLogger=INFO, file

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Follow this tutorial to learn more about log4j usage:

It's a very old post, but if it benefits anyone, we can do something like this:

Long max=((BigInteger) Collections.max(dynamics)).longValue(); 

I know this message is old and was a long time ago - but i also had problem with with the exact same error:

the problem I had was relates to the fact the encrypted text was converted to String and to byte[] when trying to DECRYPT it.

    private Key getAesKey() throws Exception {
    return new SecretKeySpec(Arrays.copyOf(key.getBytes("UTF-8"), 16), "AES");
}

private Cipher getMutual() throws Exception {
    Cipher cipher = Cipher.getInstance("AES");
    return cipher;// cipher.doFinal(pass.getBytes());
}

public byte[] getEncryptedPass(String pass) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.ENCRYPT_MODE, getAesKey());
    byte[] encrypted = cipher.doFinal(pass.getBytes("UTF-8"));
    return encrypted;

}

public String getDecryptedPass(byte[] encrypted) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.DECRYPT_MODE, getAesKey());
    String realPass = new String(cipher.doFinal(encrypted));
    return realPass;
}

None of the answers posted here worked for me. Here is what did work:

java.nio.file.Paths.get(
  getClass().getProtectionDomain().getCodeSource().getLocation().toURI()
);

Edit: The final version in my code:

URL myURL = getClass().getProtectionDomain().getCodeSource().getLocation();
java.net.URI myURI = null;
try {
    myURI = myURL.toURI();
} catch (URISyntaxException e1) 
{}
return java.nio.file.Paths.get(myURI).toFile().toString()

I could use the GetBody from Request package.

Look this comment in source code from request.go in net/http:

GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."

GetBody func() (io.ReadCloser, error)

This way you can get the body request without make it empty.

Sample:

getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
    // Do something return err
}
http.DefaultClient.Do(request)

There isn't, where would it go?

Use CSS to put a border-right on an element if you want something like that.

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.

'ZERO' for unlimited time.

C:\Apache24\htdocs\phpmyadmin\libraries\Config.class.php

/**
 * maximum execution time in seconds (0 for no limit)
 *
 * @global integer $cfg['ExecTimeLimit']
 */
$cfg['ExecTimeLimit'] = 0;

You could also import the large file right from MySQL as query or a PHP query.

500,000 rows just took me 18 seconds to import on local server, using this method.

(create table first) - then:

LOAD DATA LOCAL INFILE 'Path_To_Your_File.csv' 
INTO TABLE Your_Table_Name 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n' 

The two classes are functionally equivalent, except that System.Timers.Timer has an option to invoke all its timer expiration callbacks through ISynchronizeInvoke by setting SynchronizingObject. Otherwise, both timers invoke expiration callbacks on thread pool threads.

When you drag a System.Timers.Timer onto a Windows Forms design surface, Visual Studio sets SynchronizingObject to the form object, which causes all expiration callbacks to be called on the UI thread.

Try this:

<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>  
<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>

JS Code

function search(ele) {
    if(event.key === 'Enter') {
        alert(ele.value);        
    }
}

bind: It binds the function with provided value and context but it does not executes the function. To execute function you need to call the function.

call: It executes the function with provided context and parameter.

apply: It executes the function with provided context and parameter as array.

Twitter now lets you send the URL through a data attribute. This works great for me:

For me the answer was that I was passing two parameters to and execute SQL task, but only using one. I was doing some testing and commented out a section of code using the second parameter. I neglected to remove the parameter mapping.

So ensure you are passing in the correct number of parameters in the parameter mapping if you are using the Execute SQL task.

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Simple PHP mail script

Using a script like that, you'd POST the contents of your web form to the script, using a function like this:

jQuery.post

And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.

Use the Process class. The MSDN documentation has an example how to use it.

This solution seems not working for me.

select {
    border: 0px;
    outline: 0px;
}

But you may set select border to the background color of the container and it will work.

This works too, with the semi-colon.

This comment is for readers who have found this entry but are using mysql instead of oracle! on mysql you can do the following: Today

SELECT  * 
FROM 
WHERE date(tran_date) = CURRENT_DATE()

Yesterday

SELECT  * 
FROM yourtable 
WHERE date(tran_date) = DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)

From your original code it looks like what you want is to check if the list was empty:

var getResult= keyValueList.SingleOrDefault();
if (keyValueList.Count == 0)
{
   /* default */
}
else
{
}

You can simply use pkill -f like this:

pkill -f 'java -jar'

EDIT: To kill a particular java process running your specific jar use this regex based pkill command:

pkill -f 'java.*lnwskInterface'

There is a rails plugin called Annotate models, that will generate your model attributes on the top of your model files here is the link:

https://github.com/ctran/annotate_models

to keep the annotation in sync, you can write a task to re-generate annotate models after each deploy.

private boolean deleteFromExternalStorage(File file) {
                        String fileName = "/Music/";
                        String myPath= Environment.getExternalStorageDirectory().getAbsolutePath() + fileName;

                        file = new File(myPath);
                        System.out.println("fullPath - " + myPath);
                            if (file.exists() && file.canRead()) {
                                System.out.println(" Test - ");
                                file.delete();
                                return false; // File exists
                            }
                            System.out.println(" Test2 - ");
                            return true; // File not exists
                    }

sys.version_info doesn't seem to return a tuple as of 3.7. Rather, it returns a special class, so all of the examples using tuples don't work, for me at least. Here's the output from a python console:

>>> import sys
>>> type(sys.version_info)
<class 'sys.version_info'>

I've found that using a combination of sys.version_info.major and sys.version_info.minor seems to suffice. For example,...

import sys
if sys.version_info.major > 3:
    print('Upgrade to Python 3')
    exit(1)

checks if you're running Python 3. You can even check for more specific versions with...

import sys
ver = sys.version_info
if ver.major > 2:
    if ver.major == 3 and ver.minor <= 4:
        print('Upgrade to Python 3.5')
        exit(1)

can check to see if you're running at least Python 3.5.

Regarding client timeouts and the use of XACT_ABORT to handle them, in my opinion there is at least one very good reason to have timeouts in client APIs like SqlClient, and that is to guard the client application code from deadlocks occurring in SQL server code. In this case the client code has no fault, but has to protect it self from blocking forever waiting for the command to complete on the server. So conversely, if client timeouts have to exist to protect client code, so does XACT_ABORT ON has to protect server code from client aborts, in case the server code takes longer to execute than the client is willing to wait for.

math.log is the natural logarithm:

From the documentation:

math.log(x[, base]) With one argument, return the natural logarithm of x (to base e).

Your equation is therefore:

n = math.log((1 + (FV * r) / p) / math.log(1 + r)))

Note that in your code you convert n to a str twice which is unnecessary

Why not try find /usr/include/X11 -name Xlib.h

If there is a hit, you have Xlib.h

If not install it using sudo apt-get install libx11-dev

An int64_t should be 64 bits wide on any platform (hence the name), whereas a long can have different lengths on different platforms. In particular, sizeof(long) is often 4, ie. 32 bits.

The module jsdom is a great tool. But if you want to evaluate entire pages and do some funky stuff on them server side I suggest running them in their own context:

vm.runInContext

So things like require / CommonJS on site will not blow your Node process itself.

Variable names in PHP start with $ so $entryId is the name of a variable. $this is a special variable in Object Oriented programming in PHP, which is reference to current object. -> is used to access an object member (like properties or methods) in PHP, like the syntax in C++. so your code means this:

Place the value of variable $entryId into the entryId field (or property) of this object.

The & operator in PHP, means pass reference. Here is a example:

$b=2;
$a=$b;
$a=3;
print $a;
print $b;
// output is 32

$b=2;
$a=&$b; // note the & operator
$a=3;
print $a;
print $b;
// output is 33

In the above code, because we used & operator, a reference to where $b is pointing is stored in $a. So $a is actually a reference to $b.

In PHP, arguments are passed by value by default (inspired by C). So when calling a function, when you pass in your values, they are copied by value not by reference. This is the default IN MOST SITUATIONS. However there is a way to have pass by reference behaviour, when defining a function. Example:

function plus_by_reference( &$param ) {
      // what ever you do, will affect the actual parameter outside the function
      $param++;
}

$a=2;
plus_by_reference( $a );
echo $a;
// output is 3

There are many built-in functions that behave like this. Like the sort() function that sorts an array will affect directly on the array and will not return another sorted array.

There is something interesting to note though. Because pass-by-value mode could result in more memory usage, and PHP is an interpreted language (so programs written in PHP are not as fast as compiled programs), to make the code run faster and minimize memory usage, there are some tweaks in the PHP interpreter. One is lazy-copy (I'm not sure about the name). Which means this:

When you are coping a variable into another, PHP will copy a reference to the first variable into the second variable. So your new variable, is actually a reference to the first one until now. The value is not copied yet. But if you try to change any of these variables, PHP will make a copy of the value, and then changes the variable. This way you will have the opportunity to save memory and time, IF YOU DO NOT CHANGE THE VALUE.

So:

$b=3;
$a=$b;
// $a points to $b, equals to $a=&$b
$b=4;
// now PHP will copy 3 into $a, and places 4 into $b

After all this, if you want to place the value of $entryId into 'entryId' property of your object, the above code will do this, and will not copy the value of entryId, until you change any of them, results in less memory usage. If you actually want them both to point to the same value, then use this:

$this->entryId=&$entryId;

If you have a fixed width element and know the width of your background image, you can simply set the background-position to : the element's width - the image's width - the gap you want on the right.

For example : with a 100px-wide element and a 300px-wide image, to get a gap of 10px on the right, you set it to 100-300-10=-210px :

#myElement {
  background:url(my_image.jpg) no-repeat -210px top;
  width:100px;
}

And you get the rightmost 80 pixels of your image on the left of your element, and a gap of 20px on the right.

I know it can sound stupid but sometimes it saves the time... I use that much in a vertical manner (gap at bottom) for navigation links with text below image.

Not sure it applies to your case though.

All above answers compares well, but if you need to use custom function for mapping, and you have numpy.ndarray, and you need to retain the shape of array.

I have compare just two, but it will retain the shape of ndarray. I have used the array with 1 million entries for comparison. Here I use square function, which is also inbuilt in numpy and has great performance boost, since there as was need of something, you can use function of your choice.

import numpy, time
def timeit():
    y = numpy.arange(1000000)
    now = time.time()
    numpy.array([x * x for x in y.reshape(-1)]).reshape(y.shape)        
    print(time.time() - now)
    now = time.time()
    numpy.fromiter((x * x for x in y.reshape(-1)), y.dtype).reshape(y.shape)
    print(time.time() - now)
    now = time.time()
    numpy.square(y)  
    print(time.time() - now)

Output

>>> timeit()
1.162431240081787    # list comprehension and then building numpy array
1.0775556564331055   # from numpy.fromiter
0.002948284149169922 # using inbuilt function

here you can clearly see numpy.fromiter works great considering to simple approach, and if inbuilt function is available please use that.

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.

I had a problem where I needed the default action only after some custom action (enable otherwise disabled input fields on a form) had concluded. I wrapped the default action (submit()) into an own, recursive function (dosubmit()).

var prevdef=true;
var dosubmit=function(){
    if(prevdef==true){
        //here we can do something else first//
        prevdef=false;
        dosubmit();
    }
    else{
        $(this).submit();//which was the default action
    }
};

$('input#somebutton').click(function(){dosubmit()});

Use

serialize( )

var str = $("form").serialize();

Serialize a form to a query string, that could be sent to a server in an Ajax request.

Another option you can go with here:

df.loc["Total", "MyColumn"] = df.MyColumn.sum()

#         X  MyColumn      Y       Z
#0        A     84.0    13.0    69.0
#1        B     76.0    77.0   127.0
#2        C     28.0    69.0    16.0
#3        D     28.0    28.0    31.0
#4        E     19.0    20.0    85.0
#5        F     84.0   193.0    70.0
#Total  NaN    319.0     NaN     NaN

You can also use append() method:

df.append(pd.DataFrame(df.MyColumn.sum(), index = ["Total"], columns=["MyColumn"]))

Update:

In case you need to append sum for all numeric columns, you can do one of the followings:

Use append to do this in a functional manner (doesn't change the original data frame):

# select numeric columns and calculate the sums
sums = df.select_dtypes(pd.np.number).sum().rename('total')

# append sums to the data frame
df.append(sums)
#         X  MyColumn      Y      Z
#0        A      84.0   13.0   69.0

Try setting security to none in /etc/bluetooth/hcid.conf

http://linux.die.net/man/5/hcid.conf

This will probably only work for HCI devices (mouse, keyboard, spaceball, etc.). If you have a different kind of device, there's probably a different but similar setting to change.

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

For anyone who wants to find the build directory from a script but does not want to change it, run the following to get a list of all the build settings that point to a folder in DerivedData:

xcodebuild -showBuildSettings | grep DerivedData

If you run custom targets and schemes, please put them there as well:

xcodebuild -workspace "Foo.xcworkspace" -scheme "Bar" -sdk iphonesimulator -configuration Debug -showBuildSettings | grep DerivedData

Look at the output to locate the setting output that you want and then:

xcodebuild -showBuildSettings | grep SYMROOT | cut -d "=" -f 2 - | sed 's/^ *//'

The last part cuts the string at the equal sign and then trims the whitespace at the beginning.

If an Immutable/Singleton collections refers to the one which having only one object and which is not further gets modified, then the same functionality can be achieved by making a collection "UnmodifiableCollection" having only one object. Since the same functionality can be achieved by Unmodifiable Collection with one object, then what special purpose the Singleton Collection serves for?

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

It works, this is a problem with the tool used: normalized CSS by jsFiddle is causing the problem by hiding you the default of browsers...
See http://jsfiddle.net/XvdX9/5/

EDIT:
normalize.css stylesheet from jsFiddle adds the instruction border-collapse: collapse to all tables and it renders them completely differently in CSS2.1:

• The separated borders model
• The collapsing border model

Differences between the 2 models can be seen in this other fiddle: http://jsfiddle.net/XvdX9/11/ (with some transparencies on cells and an enormous border-radius on the top-left one, in order to see what happens on table vs its cells)

In the same CSS2.1 page about HTML tables, there are also explanations about what browsers should/could do with empty-cells in the separated borders model, the difference between border-style: none and border-style: hidden in the collapsing borders model, how width is calculated and which border should display if both table, row and cell elements define 3 different styles on the same border.

If using mentioned jquery mousewheel plugin, then what about to use the 2nd argument of event handler function - delta:

$('#my-element').on('mousewheel', function(event, delta) {
    if(delta > 0) {
    console.log('scroll up');
    } 
    else {
    console.log('scroll down');
    }
});

Starting from Matlab 2014b Python functions can be called directly. Use prefix py, then module name, and finally function name like so:

result = py.module_name.function_name(parameter1);

Make sure to add the script to the Python search path when calling from Matlab if you are in a different working directory than that of the Python script.

For all of you who believe the myth that temp variables are in memory only

First, the table variable is NOT necessarily memory resident. Under memory pressure, the pages belonging to a table variable can be pushed out to tempdb.

use NestedScrollView with viewport true is working good for me

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="700dp">

In May 2017 Google launched the official Google Maps URLs documentation. The Google Maps URLs introduces universal cross-platform syntax that you can use in your applications.

Have a look at the following document:

https://developers.google.com/maps/documentation/urls/guide

You can use URLs in search, directions, map and street view modes.

For example, to show the marker at specified position you can use the following URL:

https://www.google.com/maps/search/?api=1&query=36.26577,-92.54324

For further details please read aforementioned documentation.

You can also file feature requests for this API in Google issue tracker.

Hope this helps!

Here is another way:

If you use this template:

<% if @thing.errors.any? %>
  <ul>
    <% @thing.errors.full_messages.each do |message| %>
      <li><%= message %></li>
    <% end %>
  </ul>
<% end %>

You can write you own custom message like this:

class Thing < ActiveRecord::Base

  validate :custom_validation_method_with_message

  def custom_validation_method_with_message
    if some_model_attribute.blank?
      errors.add(:_, "My custom message")
    end
  end

This way, because of the underscore, the full message becomes " My custom message", but the extra space in the beginning is unnoticeable. If you really don't want that extra space at the beginning just add the .lstrip method.

<% if @thing.errors.any? %>
  <ul>
    <% @thing.errors.full_messages.each do |message| %>
      <li><%= message.lstrip %></li>
    <% end %>
  </ul>
<% end %>

The String.lstrip method will get rid of the extra space created by ':_' and will leave any other error messages unchanged.

Or even better, use the first word of your custom message as the key:

  def custom_validation_method_with_message
    if some_model_attribute.blank?
      errors.add(:my, "custom message")
    end
  end

Now the full message will be "My custom message" with no extra space.

If you want the full message to start with a word capitalized like "URL can't be blank" it cannot be done. Instead try adding some other word as the key:

  def custom_validation_method_with_message
    if some_model_attribute.blank?
      errors.add(:the, "URL can't be blank")
    end
  end

Now the full message will be "The URL can't be blank"

In case you use MVC to accomplish it - you will have to do something like this

 <form action="/ControllerName/ActionName" method="post">
        <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
        <input type="hidden" name="mess" value=<%=n%>/>
    </form>

I just went through some examples here and did not see the MVC one figured it won't hurt to post it.

Then on your Action in the Controller I would just put <HTTPPost> On the top of it. I believe if you don't have <HTTPGET> on the top of it it would still work but explicitly putting it there feels a bit safer.

Checkbox text may be not aligning to left with

android:button="@null"
android:drawableRight="@android:drawable/btn_radio"

in some device. Can use CheckedTextView as a replacement to avoid the problem,

<CheckedTextView
    ...
    android:checkMark="@android:drawable/btn_radio" />

and this link will be helpful: Align text left, checkbox right

Had the same problem (is not a method) with jQuery when working on autocomplete. It appeared the code was executed before the autocomplete.js was loaded. So make sure the ui.colorpicker.js is loaded before calling colorpicker.

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

If you use the Spring Framework you can do it with StringUtils:

public static String arrayToDelimitedString(Object[] arr)
public static String arrayToDelimitedString(Object[] arr, String delim)
public static String collectionToCommaDelimitedString(Collection coll)
public static String collectionToCommaDelimitedString(Collection coll, String delim)

I had a different issue that brought me to this question, which will probably be more common than the overrelease issue in the accepted answer.

Root cause was our completion block being called twice due to bad if/else fallthrough in the network handler, leading to two calls of dispatch_group_leave for every one call to dispatch_group_enter.

Completion block called multiple times:

dispatch_group_enter(group);
[self badMethodThatCallsMULTIPLECompletions:^(NSString *completion) {

    // this block is called multiple times
    // one `enter` but multiple `leave`

    dispatch_group_leave(group);
}];

Debug via the dispatch_group's count

Upon the EXC_BAD_INSTRUCTION, you should still have access to your dispatch_group in the debugger. DispatchGroup: check how many "entered"

Print out the dispatch_group and you'll see:

<OS_dispatch_group: group[0x60800008bf40] = { xrefcnt = 0x2, refcnt = 0x1, port = 0x0, count = -1, waiters = 0 }>

When you see count = -1 it indicates that you've over-left the dispatch_group. Be sure to dispatch_enter and dispatch_leave the group in matched pairs.

I've found a way to do this with a single line:

runas /user:DOMAIN\USER2 /savecred "powershell -c start-process -FilePath \"'C:\\PATH\\TO\\YOUR\\EXECUTABLE.EXE'\" -verb runAs"

There are a few tricks going on here.

1: We are telling CMD just to run Powershell as DOMAIN\USER2

2: We are passing the "Start-Process" command to Powershell, using the verb "runAs" to elevate DOMAIN\USER2 to Administrator/Elevated privilege mode.

As a general note, the escape characters in the "FilePath" argument must be present (in other words, the "\ & \\ character combinations), and the single quotation (') must surround the EXE path - this way, CMD interprets the FilePath as a single string, then Powershell uses the single quotation to interpret the FilePath as a single argument.

Using the "RunAs" verb to elevate within Powershell: http://ss64.com/ps/syntax-elevate.html

Here is the basic answer made into a reusable function:

function arrayFindReplace(array, findValue, replaceValue){
    while(array.indexOf(findValue) !== -1){
        let index = array.indexOf(findValue);
        array[index] = replaceValue;
    }
}

The string that you pass to the constructor JSONObject has to be escaped with quote():

public static java.lang.String quote(java.lang.String string)

Your code would now be:

JSONObject jsonObj = new JSONObject.quote(jsonString.toString());
System.out.println(jsonString);
System.out.println("---------------------------");
System.out.println(jsonObj);

select to_char(to_date('1/21/2000','mm/dd/yyyy'),'dd-mm-yyyy') from dual

I have got this error because my app was in a folder that have an Arabic name and I solve it with just changing the Arabic folder name to an English one and it works fine.

So make sure that all the path of your app is written in English.

If you have the code to log_out(), rewrite it. Most likely, you can do:

static FILE *logfp = ...;

void log_out(const char *fmt, ...)
{
    va_list args;

    va_start(args, fmt);
    vfprintf(logfp, fmt, args);
    va_end(args);
}

If there is extra logging information needed, that can be printed before or after the message shown. This saves memory allocation and dubious buffer sizes and so on and so forth. You probably need to initialize logfp to zero (null pointer) and check whether it is null and open the log file as appropriate - but the code in the existing log_out() should be dealing with that anyway.

The advantage to this solution is that you can simply call it as if it was a variant of printf(); indeed, it is a minor variant on printf().

If you don't have the code to log_out(), consider whether you can replace it with a variant such as the one outlined above. Whether you can use the same name will depend on your application framework and the ultimate source of the current log_out() function. If it is in the same object file as another indispensable function, you would have to use a new name. If you cannot work out how to replicate it exactly, you will have to use some variant like those given in other answers that allocates an appropriate amount of memory.

void log_out_wrapper(const char *fmt, ...)
{
    va_list args;
    size_t  len;
    char   *space;

    va_start(args, fmt);
    len = vsnprintf(0, 0, fmt, args);
    va_end(args);
    if ((space = malloc(len + 1)) != 0)
    {
         va_start(args, fmt);
         vsnprintf(space, len+1, fmt, args);
         va_end(args);
         log_out(space);
         free(space);
    }
    /* else - what to do if memory allocation fails? */
}

Obviously, you now call the log_out_wrapper() instead of log_out() - but the memory allocation and so on is done once. I reserve the right to be over-allocating space by one unnecessary byte - I've not double-checked whether the length returned by vsnprintf() includes the terminating null or not.

==

The == operator can be used to compare two variables of any kind, and it simply compares the bits.

int a = 3;
byte b = 3;
if (a == b) { // true }

Note : there are more zeroes on the left side of the int but we don't care about that here.

int a (00000011) == byte b (00000011)

Remember == operator cares only about the pattern of the bits in the variable.

Use == If two references (primitives) refers to the same object on the heap.

Rules are same whether the variable is a reference or primitive.

Foo a = new Foo();
Foo b = new Foo();
Foo c = a;

if (a == b) { // false }
if (a == c) { // true }
if (b == c) { // false }

a == c is true a == b is false

the bit pattern are the same for a and c, so they are equal using ==.

Equal():

Use the equals() method to see if two different objects are equal.

Such as two different String objects that both represent the characters in "Jane"

Since both None and "" are false, you can do both. See 6.1. Truth Value Testing.

Edit

To answer the question in your edit: No, you can assign a different type.

>>> a = ""
>>> type(a)
<type 'str'>
>>> a = 1
>>> type(a)
<type 'int'>

Oh okay, makes sense. So I did this:

    char foo[10] = "hello";
    char padded[16];
    strcpy(padded, foo);
    printf("%s", StringPadRight(padded, 15, " "));

Thanks!

You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.

Here are a couple of useful helper functions for you, they show the usage of all parameters.

#include <string>

std::string wstrtostr(const std::wstring &wstr)
{
    // Convert a Unicode string to an ASCII string
    std::string strTo;
    char *szTo = new char[wstr.length() + 1];
    szTo[wstr.size()] = '\0';
    WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
    strTo = szTo;
    delete[] szTo;
    return strTo;
}

std::wstring strtowstr(const std::string &str)
{
    // Convert an ASCII string to a Unicode String
    std::wstring wstrTo;
    wchar_t *wszTo = new wchar_t[str.length() + 1];
    wszTo[str.size()] = L'\0';
    MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
    wstrTo = wszTo;
    delete[] wszTo;
    return wstrTo;
}

--

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.

So you can understand this better:

//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
  *pX = 10;
}

int main(int argc, char ** argv)
{
  int X;
  fillXWith10(&X);
  return 0;
}

Assuming that you would really want your loop to run 24/7 as a background service

For a solution that doesn't involve injecting your code with libraries, you can simply create a service template, since you are using linux:

[Unit]
Description = <Your service description here>
After = network.target # Assuming you want to start after network interfaces are made available
 
[Service]
Type = simple
ExecStart = python <Path of the script you want to run>
User = # User to run the script as
Group = # Group to run the script as
Restart = on-failure # Restart when there are errors
SyslogIdentifier = <Name of logs for the service>
RestartSec = 5
TimeoutStartSec = infinity
 
[Install]
WantedBy = multi-user.target # Make it accessible to other users

Place that file in your daemon service folder (usually /etc/systemd/system/), in a *.service file, and install it using the following systemctl commands (will likely require sudo privileges):

systemctl enable <service file name without .service extension>

systemctl daemon-reload

systemctl start <service file name without .service extension>

You can then check that your service is running by using the command:

systemctl | grep running

On Ubuntu, the recommended way of changing the default library path for a user, is to set the R_LIBS_USER variable in the ~/.Renviron file.

touch ~/.Renviron
echo "R_LIBS_USER=/custom/path/in/absolute/form" >> ~/.Renviron

If you want to use Graph API to get current user ID then just send a request to:

https://graph.facebook.com/me?access_token=...

json_decode() will return an object or array if second value it's true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

The mysql.db table is possibly more important in determining user rights. I think an entry in it is created if you mention a table in the GRANT command. In my case the mysql.users table showed no permissions for a user when it obviously was able to connect and select, etc.

mysql> select * from mysql.db;
mysql> select * from db;
+---------------+-----------------+--------+-------------+-------------+-------------+--------
| Host          | Db              | User   | Select_priv | Insert_priv | Update_priv | Del...

Just to review, REST has certain properties that a developer should follow in order to make it RESTful:

What is REST?

According to wikipedia:

The REST architectural style describes the following six constraints applied to the architecture, while leaving the implementation of the individual components free to design:

• Client–server: Servers are not concerned with the user interface or user state, so that servers can be simpler and more scalable.
• Stateless: The client–server communication is further constrained by no client context being stored on the server between requests.
• Cacheable: Responses must, implicitly or explicitly, define themselves as cacheable, or not, to prevent clients reusing stale or inappropriate data in response to further requests.
• Layered system: A client cannot ordinarily tell whether it is connected directly to the end server, or to an intermediary along the way. Intermediary servers may improve system scalability by enabling load-balancing and by providing shared caches.
• Code on demand (optional): Servers can temporarily extend or customize the functionality of a client by the transfer of executable code.
• Uniform interface: The uniform interface between clients and servers, discussed below, simplifies and decouples the architecture, which enables each part to evolve independently. (i.e. HTTP GET, POST, PUT, PATCH, DELETE)

What the verbs should do

SO user Daniel Vasallo did a good job of laying out the responsibilities of these methods in the question Understanding REST: Verbs, error codes, and authentication:

When dealing with a Collection URI like: http://example.com/resources/

GET: List the members of the collection, complete with their member URIs for further navigation. For example, list all the cars for sale.

PUT: Meaning defined as "replace the entire collection with another collection".

POST: Create a new entry in the collection where the ID is assigned automatically by the collection. The ID created is usually included as part of the data returned by this operation.

DELETE: Meaning defined as "delete the entire collection".

So, to answer your question:

Is it right to say that I can use it with a POST query? ...

Are these two queries the same? Can I use the second variant in any case or the documentation should explicitly say that I can use both GET and POST queries?

If you were writing a plain old RPC API call, they could technically interchangeable as long as the processing server side were no different between both calls. However, in order for the call to be RESTful, calling the endpoint via the GET method should have a distinct functionality (which is to get resource(s)) from the POST method (which is to create new resources).

Side note: there is some debate out there about whether or not POST should also be allowed to be used to update resources... though i'm not commenting on that, I'm just telling you some people have an issue with that point.

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

Every answer I've read indicates the SUBSYSTEM=="usb". However, my (perhaps ancient) udev needed this to be changed to DRIVER=="usb". At last I can run the adb server as a non-root user... yay.

It can be instructive to look at the output of udevmonitor --env, followed by the output of

udevinfo -a -p <DEVICE_PATH_AS_REPORTED_BY-udevmonitor>

Try

location ~ ^/(first/location|second/location)/ {
  ...
}

The ~ means to use a regular expression for the url. The ^ means to check from the first character. This will look for a / followed by either of the locations and then another /.

SQLite has hooks built-in for encryption which are not used in the normal distribution, but here are a few implementations I know of:

• SEE - The official implementation.
• wxSQLite - A wxWidgets style C++ wrapper that also implements SQLite's encryption.
• SQLCipher - Uses openSSL's libcrypto to implement.
• SQLiteCrypt - Custom implementation, modified API.
• botansqlite3 - botansqlite3 is an encryption codec for SQLite3 that can use any algorithms in Botan for encryption.
• sqleet - another encryption implementation, using ChaCha20/Poly1305 primitives. Note that wxSQLite mentioned above can use this as a crypto provider.

The SEE and SQLiteCrypt require the purchase of a license.

Disclosure: I created botansqlite3.
