I know this answer violates the terms of your question, but I think the correct answer to your intent is simply this: use whichever algorithm allows you the longest key length, then make sure you choose a really good key. Minor differences in the performance of most well regarded algorithms (cryptographically and chronologically) are overwhelmed by a few extra bits of a key.

All of these schemes, except AES and Blowfish, have known vulnerabilities and should not be used.
However, Blowfish has been replaced by Twofish.

Simply add height: 100%; onto the #B2 styling. min-height shouldn't be necessary.

My solution. It may be slower on performance:

a = pd.concat(df[df[c] == 1] for c in df.columns if c.startswith('foo'))
a.sort_index()


   bar.baz  foo.aa  foo.bars  foo.fighters  foo.fox foo.manchu nas.foo
0      5.0     1.0         0             0        2         NA      NA
1      5.0     2.1         0             1        4          0       0
2      6.0     NaN         0           NaN        1          0       1
5      6.8     6.8         1             0        5          0       0

Or (more efficiently):

var arr = new Array(3);
arr[0] = "Zero";
arr[1] = "One";
arr[2] = "Two";

document.write(arr); // same as document.write(arr.toString()) in this context

The toString method of an array when called returns exactly what you need - comma-separated list.

Not the best way ,but will still work

There are 2 ways to configure custom error pages for ASP.NET sites:

1. Internet Information Services (IIS) Manager (the GUI)
2. web.config file

This article explains how to do each:

• How To Set Up Custom Error Pages In IIS 7.5 With ASP.NET

The reason your error.aspx page is not displaying might be because you have an error in your web.config. Try this instead:

<configuration>
   <system.web>
      <customErrors defaultRedirect="error.aspx" mode="RemoteOnly">
         <error statusCode="404" redirect="error.aspx"/>
      </customErrors>
   </system.web>
</configuration>

Direct to your ViewController again. in my situation [self.view setNeedsDisplay]; and [self viewDidLoad]; [self viewWillAppear:YES];does not work, but the method below worked.

In objective C

UIStoryboard *MyStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil ];
UIViewController *vc = [MyStoryboard instantiateViewControllerWithIdentifier:@"ViewControllerStoryBoardID"];
[self presentViewController:vc animated:YES completion:nil];

Swift:

let secondViewController = self.storyboard!.instantiateViewControllerWithIdentifier("ViewControllerStoryBoardID")   
self.presentViewController(secondViewController, animated: true, completion: nil)

This is way late to answer but it will work for latest python users:

from bs4 import BeautifulSoup
import requests 


html_page = requests.get('http://www.example.com').text

soup = BeautifulSoup(html_page, "lxml")
for link in soup.findAll('a'):
    print(link.get('href'))

Don't forget to install "requests" and "BeautifulSoup" package and also "lxml". Use .text along with get otherwise it will throw an exception.

"lxml" is used to remove that warning of which parser to be used. You can also use "html.parser" whichever fits your case.

Gustavo Niemeyer's answer is great. But in Windows, runtime proc is mostly in another dir, like this:

"C:\Users\XXX\AppData\Local\Temp"

If you use relative file path, like "/config/api.yaml", this will use your project path where your code exists.

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

this is php code I used, reply is usually like this:

    2 packets transmitted, 2 received, 0% packet loss, time 1089ms

So I used code like this:

  

    $ping_how_many = 2;
    $ping_result = shell_exec('ping -c '.$ping_how_many.' bing.com');
    if( !preg_match('/'.$ping_how_many.' received/',$ping_result) ){
       echo 'Bad ping result'. PHP_EOL;
        // goto next1;
    } 

The best way to solve your problem is to set the UseSystemPasswordChar property to true. Then, the Caps-lock message is shown when the user enters the field and the Caps-Lock is on (at least for Vista and Windows 7).

Another alternative is to set the PasswordChar property to a character value (* for example). This also triggers the automatic Caps-Lock handling.

This is an alternative solution, but one could argue it doesn't add enough value to make it worth it:

import com.google.common.collect.Iterables;
...
Iterator<String> iter = Iterables.cycle(list).iterator();
if(iter.hasNext()) {
    str = iter.next();
}

Calling hasNext() will reset the iterator cursor to the beginning if it's a the end.

You can also try the Regex class.

var regex = new Regex( "camel", RegexOptions.IgnoreCase ); var newSentence = regex.Replace( sentence, "horse" );

The environment variables displayed in Jenkins (Manage Jenkins -> System information) are inherited from the system (i.e. inherited environment variables)

If you run env command in a shell you should see the same environment variables as Jenkins shows.

These variables are either set by the shell/system or by you in ~/.bashrc, ~/.bash_profile.

There are also environment variables set by Jenkins when a job executes, but these are not displayed in the System Information.

The simplest way to do this is by

df["DateColumn"] = (df["DateColumn"]).dt.days

try this

Execute this SQL:

SHOW TABLE STATUS LIKE '<tablename>'

and fetch the value of the field Auto_increment

Depends on your compiler, but on any modern compiler there is generally no difference. It's something you shouldn't worry about. Concentrate on the maintainability of your code.

• npm install installs the depedendencies in your package.json config.
• npm run build runs the script "build" and created a script which runs your application - let's say server.js
• npm start runs the "start" script which will then be "node server.js"

It's difficult to tell exactly what the issue was but basically if you look at your scripts configuration, I would guess that "build" uses some kind of build tool to create your application while "start" assumes the build has been done but then fails if the file is not there.

You are probably using bower or grunt - I seem to remember that a typical grunt application will have defined those scripts as well as a "clean" script to delete the last build.

Build tools tend to create a file in a bin/, dist/, or build/ folder which the start script then calls - e.g. "node build/server.js". When your npm start fails, it is probably because you called npm clean or similar to delete the latest build so your application file is not present causing npm start to fail.

npm build's source code - to touch on the discussion in this question - is in github for you to have a look at if you like. If you run npm build directly and you have a "build" script defined, it will exit with an error asking you to call your build script as npm run-script build so it's not the same as npm run script.

I'm not quite sure what npm build does, but it seems to be related to postinstall and packaging scripts in dependencies. I assume that this might be making sure that any CLI build scripts's or native libraries required by dependencies are built for the specific environment after downloading the package. This will be why link and install call this script.

"error: unmappable character for encoding UTF-8" means, java has found a character which is not representing in UTF-8. Hence open the file in an editor and set the character encoding to UTF-8. You should be able to find a character which is not represented in UTF-8.Take off this character and recompile.

Use style="display:none" in your dropdown list tag and in jquery use the following to display and hide.

$("#yourdropdownid").css('display', 'inline');

OR

$("#yourdropdownid").css('display', 'none');

In Manifest theme sets with style name (AppTheme and myDialog)/ You can set new styles in styles.xml

</application>

styles.xml example

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Black">

In parent you set actualy the theme

For the general case of deeply nested lists with 3 or more levels like the ones obtained from a nested JSON:

{
"2015": {
  "spain": {"population": 43, "GNP": 9},
  "sweden": {"population": 7, "GNP": 6}},
"2016": {
  "spain": {"population": 45, "GNP": 10},
  "sweden": {"population": 9, "GNP": 8}}
}

consider the approach of melt() to convert the nested list to a tall format first:

myjson <- jsonlite:fromJSON(file("test.json"))
tall <- reshape2::melt(myjson)[, c("L1", "L2", "L3", "value")]
    L1     L2         L3 value
1 2015  spain population    43
2 2015  spain        GNP     9
3 2015 sweden population     7
4 2015 sweden        GNP     6
5 2016  spain population    45
6 2016  spain        GNP    10
7 2016 sweden population     9
8 2016 sweden        GNP     8

followed by dcast() then to wide again into a tidy dataset where each variable forms a a column and each observation forms a row:

wide <- reshape2::dcast(tall, L1+L2~L3) 
# left side of the formula defines the rows/observations and the 
# right side defines the variables/measurements
    L1     L2 GNP population
1 2015  spain   9         43
2 2015 sweden   6          7
3 2016  spain  10         45
4 2016 sweden   8          9

I have this hunk in my .gitconfig and it seems to work fine (disabled for both diff and show):

Where T2 is the table to which you're adding the constraint:

SELECT *
FROM T2
WHERE constrained_field NOT
IN (
    SELECT DISTINCT t.constrained_field
    FROM T2 
    INNER JOIN T1 t
    USING ( constrained_field )
)

And delete the results.

I fixed this error by upgrading the app from .Net Framework 4.5 to 4.6.2.

TLS-1.2 was correctly installed on the server, and older versions like TLS-1.1 were disabled. However, .Net 4.5 does not support TLS-1.2.

you can try this.

        // function body
    });
    $('.class').off().on('click', function() {
        // function body
    });

Here is the same problem.

You need to set table-layout:fixed and a suitable width on the table element, as well as overflow:hidden and white-space: nowrap on the table cells.

Examples

Fixed width columns

The width of the table has to be the same (or smaller) than the fixed width cell(s).

With one fixed width column:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 100px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

With multiple fixed width columns:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 200px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

Fixed and fluid width columns

A width for the table must be set, but any extra width is simply taken by the fluid cell(s).

With multiple columns, fixed width and fluid width:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  background: #F00;
  padding: 20px;
  border: solid 1px #000;
}
tr td:first-child {
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

Hi Please find the answer below.this is done by validating the date newly created

var year=2019;
var month=2;
var date=31;
var d = new Date(year, month - 1, date);
if (d.getFullYear() != year
        || d.getMonth() != (month - 1)
        || d.getDate() != date) {
    alert("invalid date");
    return false;
}

my_function = function(hash) { /* use hash.options and hash.content */ };

and then call:

my_function ({ options: options });
my_function ({ options: options, content: content });

Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.

If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.

If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("#el").offset().top - $(document).scrollTop()

If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

core.autocrlf value does not depend on OS type but on Windows default value is true and for Linux - input. I explored 3 possible values for commit and checkout cases and this is the resulting table:

Bash 3.0+ can use this syntax:

for i in {1..10} ; do ... ; done

..which avoids spawning an external program to expand the sequence (such as seq 1 10).

Of course, this has the same problem as the for(()) solution, being tied to bash and even a particular version (if this matters to you).

You need this instead:

if(s.contains("+"))

contains() method of String class does not take regular expression as a parameter, it takes normal text.

EDIT:

String s = "ddjdjdj+kfkfkf";

if(s.contains("+"))
{
    String parts[] = s.split("\\+");
    System.out.print(parts[0]);
}

OUTPUT:

ddjdjdj

I wanted to provide with a solution inspired by physics.

Imagine a force applied along the line and you are measuring the torque of the force about the point. If the torque is positive (counterclockwise) then the point is to the "left" of the line, but if the torque is negative the point is the "right" of the line.

So if the force vector equals the span of the two points defining the line

fx = x_2 - x_1
fy = y_2 - y_1

you test for the side of a point (px,py) based on the sign of the following test

var torque = fx*(py-y_1)-fy*(px-x_1)
if  torque>0  then
     "point on left side"
else if torque <0 then
     "point on right side"  
else
     "point on line"
end if

The Symfony documentation now explicitly shows how to do this:

$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
    'SELECT p
    FROM AppBundle:Product p
    WHERE p.price > :price
    ORDER BY p.price ASC'
)->setParameter('price', '19.99');    
$products = $query->getResult();

From http://symfony.com/doc/2.8/book/doctrine.html#querying-for-objects-with-dql

How about iTextSharp?

iText is a PDF (among others) generation library that is also ported (and kept in sync) to C#.

.* and .+ are for any chars except for new lines.

Double Escaping

Just in case, you would wanted to include new lines, the following expressions might also work for those languages that double escaping is required such as Java or C++:

[\\s\\S]*
[\\d\\D]*
[\\w\\W]*

for zero or more times, or

[\\s\\S]+
[\\d\\D]+
[\\w\\W]+

for one or more times.

Single Escaping:

Double escaping is not required for some languages such as, C#, PHP, Ruby, PERL, Python, JavaScript:

[\s\S]*
[\d\D]*
[\w\W]*
[\s\S]+
[\d\D]+
[\w\W]+

RegEx Circuit

jex.im visualizes regular expressions:

Here's a C# method to do this. Remember to add your own error handling - this mostly assumes that things work for the sake of brevity. It's 4.0+ framework only, but that's mostly because of the optional worksheetNumber parameter. You can overload the method if you need to support earlier versions.

static void ConvertExcelToCsv(string excelFilePath, string csvOutputFile, int worksheetNumber = 1) {
   if (!File.Exists(excelFilePath)) throw new FileNotFoundException(excelFilePath);
   if (File.Exists(csvOutputFile)) throw new ArgumentException("File exists: " + csvOutputFile);

   // connection string
   var cnnStr = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO\"", excelFilePath);
   var cnn = new OleDbConnection(cnnStr);

   // get schema, then data
   var dt = new DataTable();
   try {
      cnn.Open();
      var schemaTable = cnn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
      if (schemaTable.Rows.Count < worksheetNumber) throw new ArgumentException("The worksheet number provided cannot be found in the spreadsheet");
      string worksheet = schemaTable.Rows[worksheetNumber - 1]["table_name"].ToString().Replace("'", "");
      string sql = String.Format("select * from [{0}]", worksheet);
      var da = new OleDbDataAdapter(sql, cnn);
      da.Fill(dt);
   }
   catch (Exception e) {
      // ???
      throw e;
   }
   finally {
      // free resources
      cnn.Close();
   }

   // write out CSV data
   using (var wtr = new StreamWriter(csvOutputFile)) {
      foreach (DataRow row in dt.Rows) {
         bool firstLine = true;
         foreach (DataColumn col in dt.Columns) {
            if (!firstLine) { wtr.Write(","); } else { firstLine = false; }
            var data = row[col.ColumnName].ToString().Replace("\"", "\"\"");
            wtr.Write(String.Format("\"{0}\"", data));
         }
         wtr.WriteLine();
      }
   }

You will find the application folder at:

/data/data/"your package name"

you can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.

Another option is to simply use the Application log accessible via the Windows Event Viewer. The .Net error will be recorded to the Application log.

You can see these events here:

Event Viewer (Local) > Windows Logs > Application

From MSDN, here's a list of characters that aren't allowed:

Use almost any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255), except for the following:

• The following reserved characters are not allowed: < > : " / \ | ? *
• Characters whose integer representations are in the range from zero through 31 are not allowed.
• Any other character that the target file system does not allow.

But the Dollar sign must stay outside the textbox... every non-numeric or separator charachter will be cropped automatically.

Otherwise you could use a classic textbox, like described here.

You can simply convert your radian result to degree by using

math.degrees and rounding appropriately to the required decimal places

for example

>>> round(math.degrees(math.asin(0.5)),2)
30.0

Also try System.currentTimeMillis()

For me it was Docker...

I usually place node_modules/ and bower_components/ in the project directory within the default static/ folder.

Sometime a vendor/ directory for Git Submodules but usually I place them in the static/ folder.

In my opinion, the best way to do this is by implementing your own Clone() method as shown below.

class Person
{
    public string head;
    public string feet;

    // Downside: It has to be manually implemented for every class
    public Person Clone()
    {
        return new Person() { head = this.head, feet = this.feet };
    }
}

class Program
{
    public static void Main(string[] args)
    {
        Person a = new Person() { head = "bigAF", feet = "smol" };
        Person b = a.Clone();

        b.head = "notEvenThatBigTBH";

        Console.WriteLine($"{a.head}, {a.feet}");
        Console.WriteLine($"{b.head}, {b.feet}");
    }
}

Output:

bigAf, smol

notEvenThatBigTBH, smol

b is totally independent to a, due to it not being a reference, but a clone.

Hope I could help!

Example for Hamcrest:

import org.hamcrest.CoreMatchers
import org.hamcrest.MatcherAssert
import org.junit.jupiter.api.Test

class HamcrestAssertionDemo {

        val subClass = SubClass()
        MatcherAssert.assertThat(subClass, CoreMatchers.instanceOf<Any>(BaseClass::class.java))
    }

}

Example for AssertJ:

import org.junit.jupiter.api.Test

class AssertJDemo {

    @Test

Using AES or implementing AES? To use AES, there is the System.Security.Cryptography.RijndaelManaged class.

I use <br> in a CDATA tag. As an example, my strings.xml file contains an item like this:

<item><![CDATA[<b>My name is John</b><br>Nice to meet you]]></item>

and prints

My name is John
Nice to meet you

The list variable (which I would recommend to rename to something more sensible) is a reference to a list object, which can be changed.

On the line

listoflists.append((list, list[0]))

You actually are only adding a reference to the object reference by the list variable. You've got multiple possibilities to create a copy of the list, so listoflists contains the values as you seem to expect:

Use the copy library

import copy
listoflists.append((copy.copy(list), list[0]))

use the slice notation

listoflists.append((list[:], list[0]))

Basically you do the counts as sub-queries within a standard select.

An example would be the following, this returns 1 row, two columns

SELECT
 (SELECT COUNT(*) FROM MyTable WHERE MyCol = 'MyValue') AS MyTableCount,
 (SELECT COUNT(*) FROM YourTable WHERE MyCol = 'MyValue') AS YourTableCount,

JSF 1.0 / 1.1

Just put the desired logic in the constructor of the request scoped bean associated with the JSF page.

public Bean() {
    // Do your stuff here.
}

JSF 1.2 / 2.x

Use @PostConstruct annotated method on a request or view scoped bean. It will be executed after construction and initialization/setting of all managed properties and injected dependencies.

@PostConstruct
public void init() {
    // Do your stuff here.
}

This is strongly recommended over constructor in case you're using a bean management framework which uses proxies, such as CDI, because the constructor may not be called at the times you'd expect it.

JSF 2.0 / 2.1

Alternatively, use <f:event type="preRenderView"> in case you intend to initialize based on <f:viewParam> too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct is perfectly fine too.

<f:metadata>
    <f:viewParam name="foo" value="#{bean.foo}" />
    <f:event type="preRenderView" listener="#{bean.onload}" />
</f:metadata>

public void onload() { 
    // Do your stuff here.
}

JSF 2.2+

Alternatively, use <f:viewAction> in case you intend to initialize based on <f:viewParam> too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct is perfectly fine too.

<f:metadata>
    <f:viewParam name="foo" value="#{bean.foo}" />
    <f:viewAction action="#{bean.onload}" />
</f:metadata>

public void onload() { 
    // Do your stuff here.
}

Note that this can return a String navigation case if necessary. It will be interpreted as a redirect (so you do not need a ?faces-redirect=true here).

public String onload() { 
    // Do your stuff here.
    // ...
    return "some.xhtml";
}

You actually do not have to wait a full second for each request. I found that if I wait 200 miliseconds between each request I am able to avoid the OVER_QUERY_LIMIT response and the user experience is passable. With this solution you can load 20 items in 4 seconds.

$(items).each(function(i, item){

  setTimeout(function(){

    geoLocate("my address", function(myLatlng){
      ...
    });

  }, 200 * i);

}

    ArrayTest obj=new ArrayTest(1);
    test.add(obj);
    ArrayTest obj1=new ArrayTest(2);
    test.add(obj1);
    ArrayTest obj2=new ArrayTest(3);
    test.add(obj2);

    test.remove(object of ArrayTest);

you can specify how you control each object.

A True or False version, based on @DMfll answer:

try:
    # python2
    from urlparse import urlparse
except:
    # python3
    from urllib.parse import urlparse

a = 'http://www.cwi.nl:80/%7Eguido/Python.html'
b = '/data/Python.html'
c = 532
d = u'dkakasdkjdjakdjadjfalskdjfalk'

def uri_validator(x):
    try:
        result = urlparse(x)
        return all([result.scheme, result.netloc, result.path])
    except:
        return False

print(uri_validator(a))
print(uri_validator(b))
print(uri_validator(c))
print(uri_validator(d))

Gives:

True
False
False
False

I have just found ActiveSharp - Automatic INotifyPropertyChanged, I have yet to use it, but it looks good.

To quote from it's web site...

Send property change notifications without specifying property name as a string.

Instead, write properties like this:

public int Foo
{
    get { return _foo; }
    set { SetValue(ref _foo, value); }  // <-- no property name here
}

Note that there is no need to include the name of the property as a string. ActiveSharp reliably and correctly figures that out for itself. It works based on the fact that your property implementation passes the backing field (_foo) by ref. (ActiveSharp uses that "by ref" call to identify which backing field was passed, and from the field it identifies the property).

Since nullptr is never going to be returned, I recommend the reference approach. It more accurately represents how the return value will be used.

Outdated answer. Please use dplyr::sample_frac() or dplyr::sample_n() instead.

In my R package there is a function sample.rows just for this purpose:

install.packages('kimisc')

library(kimisc)
example(sample.rows)

smpl..> set.seed(42)

smpl..> sample.rows(data.frame(a=c(1,2,3), b=c(4,5,6),
                               row.names=c('a', 'b', 'c')), 10, replace=TRUE)
    a b
c   3 6
c.1 3 6
a   1 4
c.2 3 6
b   2 5
b.1 2 5
c.3 3 6
a.1 1 4
b.2 2 5
c.4 3 6

Enhancing sample by making it a generic S3 function was a bad idea, according to comments by Joris Meys to a previous answer.

The current answers are a bit out of date so, for clarity:

The short answer is:

1. Do a bare clone of the public repo.
2. Create a new private one.
3. Do a mirror push to the new private one.

This is documented on GitHub: duplicating-a-repository

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

You have a bad table design. You can't autoincrement a string, that doesn't make any sense. You have basically two options:

1.) change type of ID to int instead of string
2.) not recommended!!! - handle autoincrement by yourself. You first need to get the latest value from the database, parse it to the integer, increment it and attach it to the entity as a string again. VERY BAD idea

First option requires to change every table that has a reference to this table, BUT it's worth it.

As i also faced the same problem and because some people here commented that the solution wasn't working for them, here's the link to the post where a working solution has been found.

https://stackoverflow.com/a/24406721/3751590

Also see the "Update" in the best answer for using Cygwin terminal

isset() is not an effective way to validate text inputs and text boxes from a HTML form

You can rewrite that as "isset() is not a way to validate input." To validate input, use PHP's filter extension. filter_has_var() will tell you whether the variable exists while filter_input() will actually filter and/or sanitize the input.

Note that you don't have to use filter_has_var() prior to filter_input() and if you ask for a variable that is not set, filter_input() will simply return null.

%x is a format specifier that format and output the hex value. If you are providing int or long value, it will convert it to hex value.

%02x means if your provided value is less than two digits then 0 will be prepended.

You provided value 16843009 and it has been converted to 1010101 which a hex value.

A sample - write multiple rows with boolean column (using example above by GaretJax and Eran?).

import csv
RESULT = [['IsBerry','FruitName'],
          [False,'apple'],
          [True, 'cherry'],
          [False,'orange'],
          [False,'pineapple'],
          [True, 'strawberry']]
with open("../datasets/dashdb.csv", 'wb') as resultFile:
    wr = csv.writer(resultFile, dialect='excel')
    wr.writerows(RESULT)

Result:

df_data_4 = pd.read_csv('../datasets/dashdb.csv')
df_data_4.head()

Output:

   IsBerry  FruitName
   0    False   apple
   1    True    cherry
   2    False   orange
   3    False   pineapple
   4    True    strawberry

The most straight forward answer to this question is: You can't.

Youtube doesn't output their video's in the right format, thus they can't be embedded in a
<video/> element.

There are a few solutions posted using javascript, but don't trust on those, they all need a fallback, and won't work cross-browser.

Although similar in general cases ("run and get results for many tasks"), each function has some specific functionality for other cases:

asyncio.gather()

Returns a Future instance, allowing high level grouping of tasks:

import asyncio
from pprint import pprint

import random


async def coro(tag):
    print(">", tag)
    await asyncio.sleep(random.uniform(1, 3))
    print("<", tag)
    return tag


loop = asyncio.get_event_loop()

group1 = asyncio.gather(*[coro("group 1.{}".format(i)) for i in range(1, 6)])
group2 = asyncio.gather(*[coro("group 2.{}".format(i)) for i in range(1, 4)])
group3 = asyncio.gather(*[coro("group 3.{}".format(i)) for i in range(1, 10)])

all_groups = asyncio.gather(group1, group2, group3)

results = loop.run_until_complete(all_groups)

loop.close()

pprint(results)

All tasks in a group can be cancelled by calling group2.cancel() or even all_groups.cancel(). See also .gather(..., return_exceptions=True),

asyncio.wait()

Supports waiting to be stopped after the first task is done, or after a specified timeout, allowing lower level precision of operations:

import asyncio
import random


async def coro(tag):
    print(">", tag)
    await asyncio.sleep(random.uniform(0.5, 5))
    print("<", tag)
    return tag


loop = asyncio.get_event_loop()

tasks = [coro(i) for i in range(1, 11)]

print("Get first result:")
finished, unfinished = loop.run_until_complete(
    asyncio.wait(tasks, return_when=asyncio.FIRST_COMPLETED))

for task in finished:
    print(task.result())
print("unfinished:", len(unfinished))

print("Get more results in 2 seconds:")
finished2, unfinished2 = loop.run_until_complete(
    asyncio.wait(unfinished, timeout=2))

for task in finished2:
    print(task.result())
print("unfinished2:", len(unfinished2))

print("Get all other results:")
finished3, unfinished3 = loop.run_until_complete(asyncio.wait(unfinished2))

for task in finished3:
    print(task.result())

loop.close()

here is another way to do this

if(!Yii::$app->request->getIsPost()) {
    return Yii::$app->getResponse()->redirect(array('/user/index',302));
}

Oddly enough, new Array(size) is almost 2x faster than [] in Chrome, and about the same in FF and IE (measured by creating and filling an array). It only matters if you know the approximate size of the array. If you add more items than the length you've given, the performance boost is lost.

More accurately: Array( is a fast constant time operation that allocates no memory, wheras [] is a linear time operation that sets type and value.

This is pretty simple here is an example

Add your command code here like:

if (cmd === `!dm`) {
 let dUser =
  message.guild.member(message.mentions.users.first()) ||
  message.guild.members.get(args[0]);
 if (!dUser) return message.channel.send("Can't find user!");
 if (!message.member.hasPermission('ADMINISTRATOR'))
  return message.reply("You can't you that command!");
 let dMessage = args.join(' ').slice(22);
 if (dMessage.length < 1) return message.reply('You must supply a message!');

 dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);

 message.author.send(
  `${message.author} You have sent your message to ${dUser}`
 );
}

By default in Eclipse you only have to press Ctrl-space for autocomplete. Then select the desired method and wait 500ms for the javadoc info to pop up. If this doesn't work go to the Eclipse Windows menu -> Preferences -> Java -> Editor -> Content assist and check your settings here

Quick Overview: index and find

Next to the find method there is as well index. find and index both yield the same result: returning the position of the first occurrence, but if nothing is found index will raise a ValueError whereas find returns -1. Speedwise, both have the same benchmark results.

s.find(t)    #returns: -1, or index where t starts in s
s.index(t)   #returns: Same as find, but raises ValueError if t is not in s

Additional knowledge: rfind and rindex:

In general, find and index return the smallest index where the passed-in string starts, and rfind and rindex return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting with r indicate that the search happens from right to left.

So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind or rindex would be faster.

s.rfind(t)   #returns: Same as find, but searched right to left
s.rindex(t)  #returns: Same as index, but searches right to left

tl;dr

In UTC:

Instant.now().minus( 1 , ChronoUnit.HOURS ) 

Or, zoned:

Instant.now()
       .atZone( ZoneId.of ( "America/Montreal" ) )
       .minusHours( 1 )

Using java.time

Java 8 and later has the new java.time framework built-in.

Instant

If you only care about UTC (GMT), then use the Instant class.

Instant instant = Instant.now ();
Instant instantHourEarlier = instant.minus ( 1 , ChronoUnit.HOURS );

Dump to console.

System.out.println ( "instant: " + instant + " | instantHourEarlier: " + instantHourEarlier );

instant: 2015-10-29T00:37:48.921Z | instantHourEarlier: 2015-10-28T23:37:48.921Z

Note how in this instant happened to skip back to yesterday’s date.

ZonedDateTime

If you care about a time zone, use the ZonedDateTime class. You can start with an Instant and the assign a time zone, a ZoneId object. This class handles the necessary adjustments for anomalies such as Daylight Saving Time (DST).

Instant instant = Instant.now ();
ZoneId zoneId = ZoneId.of ( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant ( instant , zoneId );
ZonedDateTime zdtHourEarlier = zdt.minus ( 1 , ChronoUnit.HOURS );

Dump to console.

System.out.println ( "instant: " + instant + "\nzdt: " + zdt + "\nzdtHourEarlier: " + zdtHourEarlier );

instant: 2015-10-29T00:50:30.778Z

zdt: 2015-10-28T20:50:30.778-04:00[America/Montreal]

zdtHourEarlier: 2015-10-28T19:50:30.778-04:00[America/Montreal]

Conversion

The old java.util.Date/.Calendar classes are now outmoded. Avoid them. They are notoriously troublesome and confusing.

When you must use the old classes for operating with old code not yet updated for the java.time types, call the conversion methods. Here is example code going from an Instant or a ZonedDateTime to a java.util.Date.

java.util.Date date = java.util.Date.from( instant );

…or…

java.util.Date date = java.util.Date.from( zdt.toInstant() );

About java.time

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

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

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

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

Where to obtain the java.time classes?

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

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

You can use:

File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO

If you have an enumerable and not an array, you can use:

File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq

Use the following to evaluate an expression (constant 0 evaluates to false).

#if 0
 ...
#endif

This exact question is answered on mySql workbench-faq:

Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.

That means hover over an acronym in the mySql Workbench table editor.

Section 8.1.11.2, “The Columns Tab”

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

Another good GUI designer for Eclipse is Window Builder Pro. Like Jigloo, it's not free for commercial use.

It allows you to design user interfaces for Swing, SWT and even the Google Web Toolkit (GWT).

I was looking for a way to sample a few members of the GroupBy obj - had to address the posted question to get this done.

create groupby object based on some_key column

grouped = df.groupby('some_key')

pick N dataframes and grab their indices

sampled_df_i  = random.sample(grouped.indices, N)

grab the groups

df_list  = map(lambda df_i: grouped.get_group(df_i), sampled_df_i)

optionally - turn it all back into a single dataframe object

sampled_df = pd.concat(df_list, axis=0, join='outer')

It is hard to tell for sure, but here are two "close" things that can help.

$ ps aux

will give you Virtual Size (VSZ)

You can also get detailed statistics from the /proc file-system by going to /proc/$pid/status.

The most important is the VmSize, which should be close to what ps aux gives.

You should loop by rows and then columns with a structure like

for ...row index...
  for ...column index...
    print

but I guess this is homework so just try it out yourself.

Swap the row/column index in the for loops depending on if you need to go across first and then down, vs. down first and then across.

You can use: if(-e $base_path)

For multiple interval types use a nested construction as in:

 UPDATE table SET date = DATE_ADD(DATE_ADD(date, INTERVAL 1 YEAR), INTERVAL 1 DAY)

For updating a given date in the column date to 1 year + 1 day

Assuming the original date is in cell A1:

=DATE(YEAR(A1), MONTH(A1), DAY(A1)-180)

It is very simple. For example : in you JS controller use this:

$scope.inputngmodel.$valid = false;

or

$scope.inputngmodel.$invalid = true;

or

$scope.formname.inputngmodel.$valid = false;

or

$scope.formname.inputngmodel.$invalid = true;

All works for me for different requirement. Hit up if this solve your problem.

I'm looking at a similar problem, and I've found some of the best references come from chemistry (from peaks finding in mass-spec data). For a good thorough review of peaking finding algorithms read this. This is one of the best clearest reviews of peak finding techniques that I've run across. (Wavelets are the best for finding peaks of this sort in noisy data.).

It looks like your peaks are clearly defined and aren't hidden in the noise. That being the case I'd recommend using smooth savtizky-golay derivatives to find the peaks (If you just differentiate the data above you'll have a mess of false positives.). This is a very effective technique and is pretty easy to implemented (you do need a matrix class w/ basic operations). If you simply find the zero crossing of the first S-G derivative I think you'll be happy.

Just uninstall NPCAP and install wpcap. This will fix the issue.

Closing the solution completely and rerunning the project solved my issue.

String extends Object, which means an Object. Object o = a; If you really want to get as Object, you may do like below.

String s = "Hi";

Object a =s;

-p|--parent will be used if you are trying to create a directory with top-down approach. That will create the parent directory then child and so on iff none exists.

-p, --parents no error if existing, make parent directories as needed

About rlidwka it means giving full or administrative access. Found it here https://itservices.stanford.edu/service/afs/intro/permissions/unix.

Because when you do shift() on an array, it changes the length of the array. So the for loop will be messed up. You can loop through from end to front to avoid this problem.

Btw, I assume you try to remove the element at the position i rather than the first element of the array. ($scope.items.shift(); in your code will remove the first element of the array)

for(var i = $scope.items.length - 1; i >= 0; i--){
    if($scope.items[i].name == 'ted'){
        $scope.items.splice(i,1);
    }
}

The custom style sheets that we have are static pages in our local file system. In order for server to serve static files, we have to use,

app.use(express.static("public"));

where,

public is a folder we have to create inside our root directory and it must have other folders like css, images.. etc

The directory structure would look like :

Then in your html file, refer to the style.css as

<link type="text/css" href="css/styles.css" rel="stylesheet">

Another "trick" for generating the column list is simply to drag the "Columns" node from Object Explorer onto a query window.

This answer goes over some of the cases that have not been discussed above.
The return statement allows you to terminate the execution of a function before you reach the end. This causes the flow of execution to immediately return to the caller.

In line number 4:

def ret(n):
    if n > 9:
         temp = "two digits"
         return temp     #Line 4        
    else:
         temp = "one digit"
         return temp     #Line 8
    print("return statement")
ret(10)

After the conditional statement gets executed the ret() function gets terminated due to return temp (line 4). Thus the print("return statement") does not get executed.

Output:

two digits   

This code that appears after the conditional statements, or the place the flow of control cannot reach, is the dead code.

Returning Values
In lines number 4 and 8, the return statement is being used to return the value of a temporary variable after the condition has been executed.

To bring out the difference between print and return:

def ret(n):
    if n > 9:
        print("two digits")
        return "two digits"           
    else :
        print("one digit")
        return "one digit"        
ret(25)

Output:

two digits
'two digits'

In your R script, called test.R:

args <- commandArgs(trailingOnly = F)
myargument <- args[length(args)]
myargument <- sub("-","",myargument)
print(myargument)
q(save="no")

From the command line run:

R CMD BATCH -4 test.R

Your output file, test.Rout, will show that the argument 4 has been successfully passed to R:

cat test.Rout

> args <- commandArgs(trailingOnly = F)
> myargument <- args[length(args)]
> myargument <- sub("-","",myargument)
> print(myargument)
[1] "4"
> q(save="no")
> proc.time()
user  system elapsed 
0.222   0.022   0.236 

Modal Popups in Interface Builder (Storyboards)

Step 1

On the ViewController you want as your modal popup, make the background color of the root UIView clear. Tip: Do not use the root UIView as your popup. Add a new UIView that is smaller to be your popup.

Step 2

Create a Segue to the ViewController that has your popup. Select "Present Modally".

Two Methods To Create Popup From Here

Method One - Using the Segue

Select the Segue and change Presentation to "Over Current Context":

Method Two - Using the View Controller

Select the ViewController Scene that is your popup. In Attributes Inspector, under View Controller section, set Presentation to "Over Current Context":

Either method will work. That should do it!

That's because the function needs to return a value. Imagine what happens if you execute myMethod() and it doesn't go into if(condition) what would your function returns? The compiler needs to know what to return in every possible execution of your function

Checking Java documentation:

Definition: If a method declaration has a return type then there must be a return statement at the end of the method. If the return statement is not there the missing return statement error is thrown.

This error is also thrown if the method does not have a return type and has not been declared using void (i.e., it was mistakenly omitted).

You can do to solve your problem:

public String myMethod()
{
    String result = null;
    if(condition)
    {
       result = x;
    }
    return result;
}

And to consume the hidden ID input back on your Edit action method:

[HttpPost]
public ActionResult Edit(FormCollection collection)
{
    ViewModel.ID = Convert.ToInt32(collection["ID"]);
}

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

Reference: Font Awesome Get Started

Yes.

Or, if your Excel version is old enough,

Dim Sheet as WorkSheet, Pivot as PivotTable

    For Each Pivot in Sheet.PivotTables
        Pivot.RefreshTable
        Pivot.Update

Using EcmaScript 2016 you can simply do it like this.

 var arr = ["a", "a", "b"];
 var uniqueArray = Array.from(new Set(arr)); // Unique Array ['a', 'b'];

Sets are always unique, and using Array.from() you can convert a Set to an array. For reference have a look at the documentations.

It's between the Z and the C on your keyboard.

If you wish (like me) to have results containing mulitple rows of various SELECT queries "labelled" and can't manage this within the constraints of the PRINT statement in concert with the Messages tab you could turn it around and simply add messages to the Results tab per the below:

SELECT 'Results from scenario 1'
SELECT
    *
FROM tblSample

I am not sure whether v13 support library was available when this question was posted, but in case someone is still struggling, I have seen that adding android-support-v13.jar will fix everything. This is how I did it:

1. Right click on the project -> Properties
2. Select Java Build Path from from the left hand side table of content
3. Go to Libraries tab
4. Add External jars button and select <your sdk path>\extras\android\support\v13\android-support-v13.jar

This happened to me as well, and the answers given here already were not satisfying, so I did my own research.

Background: Eclipse access restrictions

Eclipse has a mechanism called access restrictions to prevent you from accidentally using classes which Eclipse thinks are not part of the public API. Usually, Eclipse is right about that, in both senses: We usually do not want to use something which is not part of the public API. And Eclipse is usually right about what is and what isn't part of the public API.

Problem

Now, there can be situations, where you want to use public Non-API, like sun.misc (you shouldn't, unless you know what you're doing). And there can be situations, where Eclipse is not really right (that's what happened to me, I just wanted to use javax.smartcardio). In that case, we get this error in Eclipse.

Solution

The solution is to change the access restrictions.

• Go to the properties of your Java project,
  • i.e. by selecting "Properties" from the context menu of the project in the "Package Explorer".
• Go to "Java Build Path", tab "Libraries".
• Expand the library entry
• select
  • "Access rules",
  • "Edit..." and
  • "Add..." a "Resolution: Accessible" with a corresponding rule pattern. For me that was "javax/smartcardio/**", for you it might instead be "com/apple/eawt/**".

You have to set Connection property of Command object and use parametersized query instead of hardcoded SQL to avoid SQL Injection.

 using(SqlConnection openCon=new SqlConnection("your_connection_String"))
    {
      string saveStaff = "INSERT into tbl_staff (staffName,userID,idDepartment) VALUES (@staffName,@userID,@idDepartment)";

      using(SqlCommand querySaveStaff = new SqlCommand(saveStaff))
       {
         querySaveStaff.Connection=openCon;
         querySaveStaff.Parameters.Add("@staffName",SqlDbType.VarChar,30).Value=name;
         .....
         openCon.Open();

         querySaveStaff.ExecuteNonQuery();
       }
     }

alias testcases="sed -n 's/func.*\(Test.*\)(.*/\1/p' | xargs | sed 's/ /|/g'"

go test -v -run $(cat coordinator_test.go | testcases)

They are not the same thing.

Consider these queries:

SELECT *
FROM Orders
LEFT JOIN OrderLines ON OrderLines.OrderID=Orders.ID
WHERE Orders.ID = 12345

and

SELECT *
FROM Orders
LEFT JOIN OrderLines ON OrderLines.OrderID=Orders.ID 
    AND Orders.ID = 12345

The first will return an order and its lines, if any, for order number 12345. The second will return all orders, but only order 12345 will have any lines associated with it.

With an INNER JOIN, the clauses are effectively equivalent. However, just because they are functionally the same, in that they produce the same results, does not mean the two kinds of clauses have the same semantic meaning.

It seems in general you're just looking for a join:

> dat1 = pd.DataFrame({'dat1': [9,5]})
> dat2 = pd.DataFrame({'dat2': [7,6]})
> dat1.join(dat2)
   dat1  dat2
0     9     7
1     5     6

In my case the route in my router was:

Route::post('/new-order', 'Api\OrderController@initiateOrder')->name('newOrder');

and from the client app I was posting the request to:

https://my-domain/api/new-order/

So, because of the trailing slash I got a 405. Hope it helps someone

another way, this will scan the table only once instead of twice if you use a subquery

only sql server 2005 and up

select Date, User, Status, Notes 
from (
       select m.*, row_number() over (partition by user order by Date desc) as rn
       from [SOMETABLE] m
     ) m2
where m2.rn = 1;

In my case the problem happened after we migrated to AndroidX. For some reason, app was calling MultiDex.install() with reflection:

    final Class<?> clazz = Class.forName("android.support.multidex.MultiDex");
    final Method method = clazz.getDeclaredMethod("install", Context.class);

I changed package from android.support.multidex.MultiDex to androidx.multidex.MultiDex. It worked.

If you got here because you're using the new ASP.NET Identity UserManager, what you're actually looking for is the RoleManager:

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));

roleManager will give you access to see if the role exists, create, etc, plus it is created for the UserManager

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

There are multiple methods of creating date as discussed above. I would not repeat same stuff. Here is small method to convert String to Date in Java Script if that is what you are looking for,

function compareDate(str1){
// str1 format should be dd/mm/yyyy. Separator can be anything e.g. / or -. It wont effect
var dt1   = parseInt(str1.substring(0,2));
var mon1  = parseInt(str1.substring(3,5));
var yr1   = parseInt(str1.substring(6,10));
var date1 = new Date(yr1, mon1-1, dt1);
return date1;
}

You can also use Dir::exist? like so:

Dir.exist?('Directory Name')

Returns true if the 'Directory Name' is a directory, false otherwise.¹

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

In windows users: open task manager and end task the nodejs.exe file, It works fine.

If you have pushed the commits upstream...

Select the commit you would like to roll back to and reverse the changes by clicking Reverse File, Reverse Hunk or Reverse Selected Lines. Do this for all the commits after the commit you would like to roll back to also.

If you have not pushed the commits upstream...

Right click on the commit and click on Reset current branch to this commit.

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

How would I accomplish the nextsibling and is there an easier way of doing this?

You may use:

tr/td[@class='name']/following-sibling::td

but I'd rather use directly:

tr[td[@class='name'] ='Brand']/td[@class='desc']

This assumes that:

1. The context node, against which the XPath expression is evaluated is the parent of all tr elements -- not shown in your question.

2. Each tr element has only one td with class attribute valued 'name' and only one td with class attribute valued 'desc'.

You don't need both hibernate.cfg.xml and persistence.xml in this case. Have you tried removing hibernate.cfg.xml and mapping everything in persistence.xml only?

But as the other answer also pointed out, this is not okay like this:

@Id
@JoinColumn(name = "categoria") 
private String id;

Didn't you want to use @Column instead?

1. open .xcodeproj file in sublime text
2. remove these two lines, if you have clean pods folders, i mean if you got the errors above after you removed pods folder

I don't know if leaving hibernate off the front makes a difference.

The reference suggests it should be hibernate.hbm2ddl.auto

A value of create will create your tables at sessionFactory creation, and leave them intact.

A value of create-drop will create your tables, and then drop them when you close the sessionFactory.

Perhaps you should set the javax.persistence.Table annotation explicitly?

Hope this helps.

The body is not fully stored as part of the response, the reason for this is because the body can contain a very large amount of data, if it was to be stored on the response object, the program's memory would be consumed quite fast.

Instead, Node.js uses a mechanism called Stream. This mechanism allows holding only a small part of the data and allows the programmer to decide if to fully consume it in memory or use each part of the data as its flowing.

There are multiple ways how to fully consume the data into memory, since HTTP Response is a readable stream, all readable methods are available on the res object

1. listening to the "data" event and saving the chunks passed to the callback

   const chunks = []
   
   res.on("data", (chunk) => {
       chunks.push(chunk)
   });
   
   res.on("end", () => {
       const body = Buffer.concat(chunks);
   });
   

When using this approach you do not interfere with the behavior of the stream and you are only gathering the data as it is available to the application.

2. using the "readble" event and calling res.read()

   const chunks = [];
   
   res.on("readable", () => {
      let chunk;
      while(null !== (chunk = res.read())){
          chunks.push(chunk)
      }
   });
   
   res.on("end", () => {
       const body = Buffer.concat(chunks);
   });
   

When going with this approach you are fully in charge of the stream flow and until res.read is called no more data will be passed into the stream.

3. using an async iterator

   const chunks = [];
   
   for await (const chunk of readable) {
       chunks.push(chunk);
   } 
   
   const body = Buffer.concat(chunks);
   

This approach is similar to the "data" event approach. It will just simplify the scoping and allow the entire process to happen in the same scope.

While as described, it is possible to fully consume data from the response it is always important to keep in mind if it is actually necessary to do so. In many cases, it is possible to simply direct the data to its destination without fully saving it into memory.

Node.js read streams, including HTTP response, have a built-in method for doing this, this method is called pipe. The usage is quite simple, readStream.pipe(writeStream);.

for example:

If the final destination of your data is the file system, you can simply open a write stream to the file system and then pipe the data to ts destination.

const { createWriteStream } = require("fs");
const writeStream = createWriteStream("someFile");
res.pipe(writeStream);

Try:

using System.Net;

public static string GetIpAddress()  // Get IP Address
{
    string ip = "";     
    IPHostEntry ipEntry = Dns.GetHostEntry(GetCompCode());
    IPAddress[] addr = ipEntry.AddressList;
    ip = addr[2].ToString();
    return ip;
}
public static string GetCompCode()  // Get Computer Name
{   
    string strHostName = "";
    strHostName = Dns.GetHostName();
    return strHostName;
}

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

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

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

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

proof of concept example is here

For showing result of batch file in text file, you can use

this command

chdir > test.txt

This command will redirect result to test.txt.

When you open test.txt you will found current path of directory in test.txt

To avoid the TOCTOU issue highlighted by Éric Araujo's comment, you can catch an exception to call the correct method:

def remove_file_or_dir(path: str) -> None:
    """ Remove a file or directory """
    try:
        shutil.rmtree(path)
    except NotADirectoryError:
        os.remove(path)

Since shutil.rmtree() will only remove directories and os.remove() or os.unlink() will only remove files.

I hope this would be helpful:

.top_image img{
display: block;
margin: 0 auto;
}

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

You can also concat df1, df2:

x = pd.concat([df1, df2])

and then remove all duplicates:

y = x.drop_duplicates(keep=False, inplace=False)

ping localhost -n (your time) >nul

example

@echo off
title Test
echo hi
ping localhost -n 3 >nul && :: will wait 3 seconds before going next command (it will not display)
echo bye! && :: still wont be any spaces (just below the hi command)
ping localhost -n 2 >nul && :: will wait 2 seconds before going to next command (it will not display)
@exit

Just wanted to share a solution for unsigned long aswell.

unsigned long ToUInt(char* str)
{
    unsigned long mult = 1;
    unsigned long re = 0;
    int len = strlen(str);
    for(int i = len -1 ; i >= 0 ; i--)
    {
        re = re + ((int)str[i] -48)*mult;
        mult = mult*10;
    }
    return re;
}

The same issue exists for a Mediawiki: It does not provide tabs, nor are consecutive spaces allowed.

Although not really a TAB function, the workaround was to add a template named 'Tab', which replaces each call (i.e. {{tab}}) by 4 non-breaking space symbols:

      

Those are not collapsed, and create a 4 space distance anywhere used.
It's not really a tab, because it would not align to fixed tab positions, but I still find many uses for it.

Maybe someone can come up with similar mechanism for a Wiki Template in HTML (CSS class or whatever).

import image from './img/one.jpg';

class Icons extends React.Component{
    render(){
      return(
        <img className='profile-image' alt='icon' src={image}/>
    );
    }
}
export default Icons;

If you have installed Android Studio more than one time, the command prompt or PowerShell assigned on the first one and maybe you are running the second one. So, browse for Android Studio, if you have more than one installation, delete the first one. Then, download the Plugins in Android Studio by following theese steps.

Step 1:Studio --> File --> Settings --> Plugins --> Browse Repositories

Step 2: Search for Flutter and download it

Step 3: When you're done restart Android Studio.

The following selects all descendant elements and disables them:

$("#dcacl").find("*").prop("disabled", true);

But it only really makes sense to disable certain element types: inputs, buttons, etc., so you want a more specific selector:

$("#dcac1").find(":input").prop("disabled",true);
// noting that ":input" gives you the equivalent of
$("#dcac1").find("input,select,textarea,button").prop("disabled",true);

To re-enable you just set "disabled" to false.

I want to Disable them at loading the page and then by a click i can enable them

OK, so put the above code in a document ready handler, and setup an appropriate click handler:

$(document).ready(function() {
    var $dcac1kids = $("#dcac1").find(":input");
    $dcac1kids.prop("disabled",true);

    // not sure what you want to click on to re-enable
    $("selector for whatever you want to click").one("click",function() {
       $dcac1kids.prop("disabled",false);
    }
}

I've cached the results of the selector on the assumption that you're not adding more elements to the div between the page load and the click. And I've attached the click handler with .one() since you haven't specified a requirement to re-disable the elements so presumably the event only needs to be handled once. Of course you can change the .one() to .click() if appropriate.

You can also use

Encoding.ASCII.GetString(ms.ToArray());

I don't think this is less efficient, but I couldn't swear to it. It also lets you choose a different encoding, whereas using a StreamReader you'd have to specify that as a parameter.

The other plus of using RecycleView is animation, it can be done in two lines of code

RecyclerView.ItemAnimator itemAnimator = new DefaultItemAnimator();
        recyclerView.setItemAnimator(itemAnimator);

But the widget is still raw, e.g you can't create header and footer.

[TL;DR? You can skip to the end for a code example.]

I actually prefer to use a different idiom, which is a little involved for using as a one off, but is nice if you have a more complex use case.

A bit of background first.

Properties are useful in that they allow us to handle both setting and getting values in a programmatic way but still allow attributes to be accessed as attributes. We can turn 'gets' into 'computations' (essentially) and we can turn 'sets' into 'events'. So let's say we have the following class, which I've coded with Java-like getters and setters.

class Example(object):
    def __init__(self, x=None, y=None):
        self.x = x
        self.y = y

    def getX(self):
        return self.x or self.defaultX()

    def getY(self):
        return self.y or self.defaultY()

    def setX(self, x):
        self.x = x

    def setY(self, y):
        self.y = y

    def defaultX(self):
        return someDefaultComputationForX()

    def defaultY(self):
        return someDefaultComputationForY()

You may be wondering why I didn't call defaultX and defaultY in the object's __init__ method. The reason is that for our case I want to assume that the someDefaultComputation methods return values that vary over time, say a timestamp, and whenever x (or y) is not set (where, for the purpose of this example, "not set" means "set to None") I want the value of x's (or y's) default computation.

So this is lame for a number of reasons describe above. I'll rewrite it using properties:

class Example(object):
    def __init__(self, x=None, y=None):
        self._x = x
        self._y = y

    @property
    def x(self):
        return self.x or self.defaultX()

    @x.setter
    def x(self, value):
        self._x = value

    @property
    def y(self):
        return self.y or self.defaultY()

    @y.setter
    def y(self, value):
        self._y = value

    # default{XY} as before.

What have we gained? We've gained the ability to refer to these attributes as attributes even though, behind the scenes, we end up running methods.

Of course the real power of properties is that we generally want these methods to do something in addition to just getting and setting values (otherwise there is no point in using properties). I did this in my getter example. We are basically running a function body to pick up a default whenever the value isn't set. This is a very common pattern.

But what are we losing, and what can't we do?

The main annoyance, in my view, is that if you define a getter (as we do here) you also have to define a setter.[1] That's extra noise that clutters the code.

Another annoyance is that we still have to initialize the x and y values in __init__. (Well, of course we could add them using setattr() but that is more extra code.)

Third, unlike in the Java-like example, getters cannot accept other parameters. Now I can hear you saying already, well, if it's taking parameters it's not a getter! In an official sense, that is true. But in a practical sense there is no reason we shouldn't be able to parameterize an named attribute -- like x -- and set its value for some specific parameters.

It'd be nice if we could do something like:

e.x[a,b,c] = 10
e.x[d,e,f] = 20

for example. The closest we can get is to override the assignment to imply some special semantics:

e.x = [a,b,c,10]
e.x = [d,e,f,30]

and of course ensure that our setter knows how to extract the first three values as a key to a dictionary and set its value to a number or something.

But even if we did that we still couldn't support it with properties because there is no way to get the value because we can't pass parameters at all to the getter. So we've had to return everything, introducing an asymmetry.

The Java-style getter/setter does let us handle this, but we're back to needing getter/setters.

In my mind what we really want is something that capture the following requirements:

• Users define just one method for a given attribute and can indicate there whether the attribute is read-only or read-write. Properties fail this test if the attribute writable.

• There is no need for the user to define an extra variable underlying the function, so we don't need the __init__ or setattr in the code. The variable just exists by the fact we've created this new-style attribute.

• Any default code for the attribute executes in the method body itself.

• We can set the attribute as an attribute and reference it as an attribute.

• We can parameterize the attribute.

In terms of code, we want a way to write:

def x(self, *args):
    return defaultX()

and be able to then do:

print e.x     -> The default at time T0
e.x = 1
print e.x     -> 1
e.x = None
print e.x     -> The default at time T1

and so forth.

We also want a way to do this for the special case of a parameterizable attribute, but still allow the default assign case to work. You'll see how I tackled this below.

Now to the point (yay! the point!). The solution I came up for for this is as follows.

We create a new object to replace the notion of a property. The object is intended to store the value of a variable set to it, but also maintains a handle on code that knows how to calculate a default. Its job is to store the set value or to run the method if that value is not set.

Let's call it an UberProperty.

class UberProperty(object):

    def __init__(self, method):
        self.method = method
        self.value = None
        self.isSet = False

    def setValue(self, value):
        self.value = value
        self.isSet = True

    def clearValue(self):
        self.value = None
        self.isSet = False

I assume method here is a class method, value is the value of the UberProperty, and I have added isSet because None may be a real value and this allows us a clean way to declare there really is "no value". Another way is a sentinel of some sort.

This basically gives us an object that can do what we want, but how do we actually put it on our class? Well, properties use decorators; why can't we? Let's see how it might look (from here on I'm going to stick to using just a single 'attribute', x).

class Example(object):

    @uberProperty
    def x(self):
        return defaultX()

This doesn't actually work yet, of course. We have to implement uberProperty and make sure it handles both gets and sets.

Let's start with gets.

My first attempt was to simply create a new UberProperty object and return it:

def uberProperty(f):
    return UberProperty(f)

I quickly discovered, of course, that this doens't work: Python never binds the callable to the object and I need the object in order to call the function. Even creating the decorator in the class doesn't work, as although now we have the class, we still don't have an object to work with.

So we're going to need to be able to do more here. We do know that a method need only be represented the one time, so let's go ahead and keep our decorator, but modify UberProperty to only store the method reference:

class UberProperty(object):

    def __init__(self, method):
        self.method = method

It is also not callable, so at the moment nothing is working.

How do we complete the picture? Well, what do we end up with when we create the example class using our new decorator:

class Example(object):

    @uberProperty
    def x(self):
        return defaultX()

print Example.x     <__main__.UberProperty object at 0x10e1fb8d0>
print Example().x   <__main__.UberProperty object at 0x10e1fb8d0>

in both cases we get back the UberProperty which of course is not a callable, so this isn't of much use.

What we need is some way to dynamically bind the UberProperty instance created by the decorator after the class has been created to an object of the class before that object has been returned to that user for use. Um, yeah, that's an __init__ call, dude.

Let's write up what we want our find result to be first. We're binding an UberProperty to an instance, so an obvious thing to return would be a BoundUberProperty. This is where we'll actually maintain state for the x attribute.

class BoundUberProperty(object):
    def __init__(self, obj, uberProperty):
        self.obj = obj
        self.uberProperty = uberProperty
        self.isSet = False

    def setValue(self, value):
        self.value = value
        self.isSet = True

    def getValue(self):
        return self.value if self.isSet else self.uberProperty.method(self.obj)

    def clearValue(self):
        del self.value
        self.isSet = False

Now we the representation; how do get these on to an object? There are a few approaches, but the easiest one to explain just uses the __init__ method to do that mapping. By the time __init__ is called our decorators have run, so just need to look through the object's __dict__ and update any attributes where the value of the attribute is of type UberProperty.

Now, uber-properties are cool and we'll probably want to use them a lot, so it makes sense to just create a base class that does this for all subclasses. I think you know what the base class is going to be called.

class UberObject(object):
    def __init__(self):
        for k in dir(self):
            v = getattr(self, k)
            if isinstance(v, UberProperty):
                v = BoundUberProperty(self, v)
                setattr(self, k, v)

We add this, change our example to inherit from UberObject, and ...

e = Example()
print e.x               -> <__main__.BoundUberProperty object at 0x104604c90>

After modifying x to be:

@uberProperty
def x(self):
    return *datetime.datetime.now()*

We can run a simple test:

print e.x.getValue()
print e.x.getValue()
e.x.setValue(datetime.date(2013, 5, 31))
print e.x.getValue()
e.x.clearValue()
print e.x.getValue()

And we get the output we wanted:

2013-05-31 00:05:13.985813
2013-05-31 00:05:13.986290
2013-05-31
2013-05-31 00:05:13.986310

(Gee, I'm working late.)

Note that I have used getValue, setValue, and clearValue here. This is because I haven't yet linked in the means to have these automatically returned.

But I think this is a good place to stop for now, because I'm getting tired. You can also see that the core functionality we wanted is in place; the rest is window dressing. Important usability window dressing, but that can wait until I have a change to update the post.

I'll finish up the example in the next posting by addressing these things:

• We need to make sure UberObject's __init__ is always called by subclasses.

  • So we either force it be called somewhere or we prevent it from being implemented.
  • We'll see how to do this with a metaclass.

• We need to make sure we handle the common case where someone 'aliases' a function to something else, such as:

    class Example(object):
        @uberProperty
        def x(self):
            ...
  
        y = x
  

• We need e.x to return e.x.getValue() by default.

  • What we'll actually see is this is one area where the model fails.
  • It turns out we'll always need to use a function call to get the value.
  • But we can make it look like a regular function call and avoid having to use e.x.getValue(). (Doing this one is obvious, if you haven't already fixed it out.)

• We need to support setting e.x directly, as in e.x = <newvalue>. We can do this in the parent class too, but we'll need to update our __init__ code to handle it.

• Finally, we'll add parameterized attributes. It should be pretty obvious how we'll do this, too.

Here's the code as it exists up to now:

import datetime

class UberObject(object):
    def uberSetter(self, value):
        print 'setting'

    def uberGetter(self):
        return self

    def __init__(self):
        for k in dir(self):
            v = getattr(self, k)
            if isinstance(v, UberProperty):
                v = BoundUberProperty(self, v)
                setattr(self, k, v)


class UberProperty(object):
    def __init__(self, method):
        self.method = method

class BoundUberProperty(object):
    def __init__(self, obj, uberProperty):
        self.obj = obj
        self.uberProperty = uberProperty
        self.isSet = False

    def setValue(self, value):
        self.value = value
        self.isSet = True

    def getValue(self):
        return self.value if self.isSet else self.uberProperty.method(self.obj)

[1] I may be behind on whether this is still the case.

Note for zsh users: replace all references to ~/.bash_profile with ~/.zshrc.

Option 1 - Using Homebrew

This is the easiest way and will provide automatic updates.

1. Install the homebrew package manager

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
   

2. Install adb

    brew install android-platform-tools
   

3. Start using adb

    adb devices
   

Option 2 - Manually (just the platform tools)

This is the easiest way to get a manual installation of ADB and Fastboot.

1. Delete your old installation (optional)

    rm -rf ~/.android-sdk-macosx/
   

2. Navigate to https://developer.android.com/studio/releases/platform-tools.html and click on the SDK Platform-Tools for Mac link.

3. Go to your Downloads folder

    cd ~/Downloads/
   

4. Unzip the tools you downloaded

    unzip platform-tools-latest*.zip 
   

5. Move them somewhere you won't accidentally delete them

    mkdir ~/.android-sdk-macosx
    mv platform-tools/ ~/.android-sdk-macosx/platform-tools
   

6. Add platform-tools to your path

    echo 'export PATH=$PATH:~/.android-sdk-macosx/platform-tools/' >> ~/.bash_profile
   

7. Refresh your bash profile (or restart your terminal app)

    source ~/.bash_profile
   

8. Start using adb

    adb devices
   

Option 3 - Manually (with SDK Manager)

1. Delete your old installation (optional)

    rm -rf ~/.android-sdk-macosx/
   

2. Download the Mac SDK Tools from the Android developer site under "Get just the command line tools". Make sure you save them to your Downloads folder.

3. Go to your Downloads folder

    cd ~/Downloads/
   

4. Unzip the tools you downloaded

    unzip tools_r*-macosx.zip 
   

5. Move them somewhere you won't accidentally delete them

    mkdir ~/.android-sdk-macosx
    mv tools/ ~/.android-sdk-macosx/tools
   

6. Run the SDK Manager

    sh ~/.android-sdk-macosx/tools/android
   

7. Uncheck everything but Android SDK Platform-tools (optional)

8. Click Install Packages, accept licenses, click Install. Close the SDK Manager window.

9. Add platform-tools to your path

    echo 'export PATH=$PATH:~/.android-sdk-macosx/platform-tools/' >> ~/.bash_profile
   

10. Refresh your bash profile (or restart your terminal app)

    source ~/.bash_profile
    

11. Start using adb

    adb devices
    

you can use the following code

         Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                pic = new File(Environment.getExternalStorageDirectory(),
                        mApp.getPreference().getString(Common.u_id, "") + ".jpg");

                picUri = Uri.fromFile(pic);

                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, picUri);

                cameraIntent.putExtra("return-data", true);
                startActivityForResult(cameraIntent, PHOTO);

I had a similar problem recently. I had a form and PHP function that to be run once the form is submitted. However, I needed to run a javascript first.

        // This variable is used in order to determine if we already did our js fun
        var window.alreadyClicked = "NO"
        $("form:not('#press')").bind("submit", function(e){
            // Check if we already run js part
            if(window.alreadyClicked == "NO"){
                // Prevent page refresh
                e.preventDefault();
                // Change variable value so next time we submit the form the js wont run
                window.alreadyClicked = "YES"
                // Here is your actual js you need to run before doing the php part
                xxxxxxxxxx

                // Submit the form again but since we changed the value of our variable js wont be run and page can reload (and php can do whatever you told it to)
                $("form:not('#press')").submit()
            } 
        });

I recently answered a similar question here. Applying the same approach to your problem would yield following solution:

list.sort(
  p2Ord(stringOrd, stringOrd).comap(new F<String, P2<String, String>>() {
    public P2<String, String> f(String s) {
      return p(s.toLowerCase(), s);
    }
  })
);

I use following code for get different result from condition That worked for me.

Select A.column, B.column
FROM TABLE1 A
INNER JOIN
TABLE2 B
ON A.Id = (case when (your condition) then b.Id else (something) END)

You could use list comprehension:

with open("names", "r") as f:
    names_list = [line.strip() for line in f if line.strip()]

Updated: Removed unnecessary readlines().

To avoid calling line.strip() twice, you can use a generator:

names_list = [l for l in (line.strip() for line in f) if l]

std::stoi from string could also be used.

    #include <string>

    using namespace std;

    int main (int argc, char** argv)
    {
         if (argc >= 2)
         {
             int val = stoi(argv[1]);
             // ...    
         }
         return 0;
    }

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

If you have more numbers or if you intend to add new test numbers for CASE then you can use a more flexible approach:

DECLARE @Numbers TABLE
(
    Number VARCHAR(50) PRIMARY KEY
    ,Class TINYINT NOT NULL
);
INSERT @Numbers
VALUES ('1121231',1);
INSERT @Numbers
VALUES ('31242323',1);
INSERT @Numbers
VALUES ('234523',2);
INSERT @Numbers
VALUES ('2342423',2);

SELECT c.*, n.Class
FROM   tblClient c  
LEFT OUTER JOIN   @Numbers n ON c.Number = n.Number;

Also, instead of table variable you can use a regular table.

Bar is guaranteed not to change the object it is being invoked on. See the section about const correctness in the C++ FAQ, for example.

$.get("file.html", function(data){
    $("#div").html(data);
});

You can increase the limit from php.ini file. If you are using windows, you will the get php.ini file from C:\xampp\php directory.

Now changes the following lines & set your limit

post_max_size = 128M
upload_max_filesize = 128M 
max_execution_time = 2000
max_input_time = 3000
memory_limit = 256M

First off, run

npm init

...will ask you a few questions (read this first) about your project/package and then generate a package.json file for you.

Then, once you have a package.json file, use

npm install <pkg> --save

or

npm install <pkg> --save-dev

...to install a dependency and automatically append it to your package.json's dependencies list.

(Note: You may need to manually tweak the version ranges for your dependencies.)

Small edit to @seengee answer: In order to work, you need curly braces around the variable, otherwise you'll get an error.

header("Content-type: {$imginfo['mime']}");

If your path environment variable contains Python (eg. C:\Python27\) you can run your py file simply from Windows command line (cmd). Howto here.

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

Interestingly putting <httpCookies httpOnlyCookies="false"/> doesn't seem to disable httpOnlyCookies in ASP.NET 2.0. Check this article about SessionID and Login Problems With ASP .NET 2.0.

Looks like Microsoft took the decision to not allow you to disable it from the web.config. Check this post on forums.asp.net

sum([1 for elem in <yourlist> if elem==<your_value>])

This will return the amount of occurences of your_value

$objPost = new Post;
$objPost->title = 'Title';
$objPost->description = 'Description';   
$objPost->save();
$recId = $objPost->id; // If Id in table column name if other then id then user the other column name

return Response::json(['success' => true,'id' => $recId], 200);

For me the issue were the multithreaded tests that were doing stubbing/verification on a shared mocks. It leaded to randomly throwing WrongTypeOfReturnValue exception.

This is not properly written test using Mockito. Mocks should not be accessed from multiple threads.

The solution was to make mocks local to each test.

The above solution is good if all the data is of same dtype. Numpy arrays are homogeneous containers. When you do df.values the output is an numpy array. So if the data has int and float in it then output will either have int or float and the columns will loose their original dtype. Consider df

a  b 
0  1  4
1  2  5 
2  3  6 

a    float64
b    int64 

So if you want to keep original dtype, you can do something like

row_list = df.to_csv(None, header=False, index=False).split('\n')

this will return each row as a string.

['1.0,4', '2.0,5', '3.0,6', '']

Then split each row to get list of list. Each element after splitting is a unicode. We need to convert it required datatype.

def f(row_str): 
  row_list = row_str.split(',')
  return [float(row_list[0]), int(row_list[1])]

df_list_of_list = map(f, row_list[:-1])

[[1.0, 4], [2.0, 5], [3.0, 6]]

A slightly lighter task that doesn't unnecessarily copy files to a dir:

task downloadDependencies(type: Exec) {
    configurations.testRuntime.files
    commandLine 'echo', 'Downloaded all dependencies'
}

Updated for kotlin & gradle 6.2.0, with buildscript dependency resolution added:

fun Configuration.isDeprecated() = this is DeprecatableConfiguration && resolutionAlternatives != null

fun ConfigurationContainer.resolveAll() = this
  .filter { it.isCanBeResolved && !it.isDeprecated() }
  .forEach { it.resolve() }

tasks.register("downloadDependencies") {
  doLast {
    configurations.resolveAll()
    buildscript.configurations.resolveAll()
  }
}

This is due to a bug in Webkit.

You can work around the Webkit bug using createEvent('Event') rather than createEvent('KeyboardEvent'), and then assigning the keyCode property. See this answer and this example.

For me the issue was that the maven sonar plugin was using proxy servers defined in the maven settings.xml. I was trying to access the sonarque on another (not localhost alias) and so it was trying to use the proxy server to access it. Just added my alias to nonProxyHosts in settings.xml and it is working now. I did not face this issue in maven sonar plugin 3.2, only after i upgraded it.

<proxy>
  <id>proxy_id</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>your-proxy-host/host>
  <port>your-proxy-host</port>
  <nonProxyHosts>localhost|127.0.*|other-non-proxy-hosts</nonProxyHosts>
</proxy>enter code here

Didn't quite see this variation in the answers yet. I had an additional constraint where I needed, given an initial seed, to select the same set of rows each time.

For MS SQL:

Minimum example:

select top 10 percent *
from table_name
order by rand(checksum(*))

Normalized execution time: 1.00

NewId() example:

select top 10 percent *
from table_name
order by newid()

Normalized execution time: 1.02

NewId() is insignificantly slower than rand(checksum(*)), so you may not want to use it against large record sets.

Selection with Initial Seed:

declare @seed int
set @seed = Year(getdate()) * month(getdate()) /* any other initial seed here */

select top 10 percent *
from table_name
order by rand(checksum(*) % seed) /* any other math function here */

If you need to select the same set given a seed, this seems to work.

Yes, you can add as many SQL statements into a single script as you wish. Just one thing to note: the order matters. You can't INSERT into a table until you CREATE it; you can't set a foreign key until the primary key is inserted.

In my case it acts like a <div> or <span> however even <span> messes up with my AngularFlex styling but ng-container doesn't.

TL;DR

Here's a version where you don't need a human to read a value and type it out themselves.

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Another option would be to employ the reusable Function shared at the end of this answer.

A non-interactive solution

Just adding to the other two answers, for those of us who need to have these Sequences created by a non-interactive script, while patching a live-ish DB for instance.

That is, when you don't wanna SELECT the value manually and type it yourself into a subsequent CREATE statement.

In short, you can not do:

CREATE SEQUENCE foo_a_seq
    START WITH ( SELECT max(a) + 1 FROM foo );

... since the START [WITH] clause in CREATE SEQUENCE expects a value, not a subquery.

Note: As a rule of thumb, that applies to all non-CRUD (i.e.: anything other than INSERT, SELECT, UPDATE, DELETE) statements in pgSQL AFAIK.

However, setval() does! Thus, the following is absolutely fine:

SELECT setval('foo_a_seq', max(a)) FROM foo;

If there's no data and you don't (want to) know about it, use coalesce() to set the default value:

SELECT setval('foo_a_seq', coalesce(max(a), 0)) FROM foo;
--                         ^      ^         ^
--                       defaults to:       0

However, having the current sequence value set to 0 is clumsy, if not illegal.
Using the three-parameter form of setval would be more appropriate:

--                                             vvv
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
--                                                  ^   ^
--                                                is_called

Setting the optional third parameter of setval to false will prevent the next nextval from advancing the sequence before returning a value, and thus:

the next nextval will return exactly the specified value, and sequence advancement commences with the following nextval.

— from this entry in the documentation

On an unrelated note, you also can specify the column owning the Sequence directly with CREATE, you don't have to alter it later:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;

In summary:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Using a Function

Alternatively, if you're planning on doing this for multiple columns, you could opt for using an actual Function.

CREATE OR REPLACE FUNCTION make_into_serial(table_name TEXT, column_name TEXT) RETURNS INTEGER AS $$
DECLARE
    start_with INTEGER;
    sequence_name TEXT;
BEGIN
    sequence_name := table_name || '_' || column_name || '_seq';
    EXECUTE 'SELECT coalesce(max(' || column_name || '), 0) + 1 FROM ' || table_name
            INTO start_with;
    EXECUTE 'CREATE SEQUENCE ' || sequence_name ||
            ' START WITH ' || start_with ||
            ' OWNED BY ' || table_name || '.' || column_name;
    EXECUTE 'ALTER TABLE ' || table_name || ' ALTER COLUMN ' || column_name ||
            ' SET DEFAULT nextVal(''' || sequence_name || ''')';
    RETURN start_with;
END;
$$ LANGUAGE plpgsql VOLATILE;

Use it like so:

INSERT INTO foo (data) VALUES ('asdf');
-- ERROR: null value in column "a" violates not-null constraint

SELECT make_into_serial('foo', 'a');
INSERT INTO foo (data) VALUES ('asdf');
-- OK: 1 row(s) affected

For red lines an points

plt.plot(dates, values, '.r-') 

or for x markers and blue lines

plt.plot(dates, values, 'xb-')

MD5 is bad because of collision problems - two different passwords possibly generating the same md-5.

Sha-1 would be plenty secure for this. The reason you store the salted sha-1 version of the password is so that you the swerver do not keep the user's apassword on file, that they may be using with other people's servers. Otherwise, what difference does it make?

If the hacker steals your entire unencrypted database some how, the only thing a hashed salted password does is prevent him from impersonating the user for future signons - the hacker already has the data.

What good does it do the attacker to have the hashed value, if what your user inputs is a plain password?

And even if the hacker with future technology could generate a million sha-1 keys a second for a brute force attack, would your server handle a million logons a second for the hacker to test his keys? That's if you are letting the hacker try to logon with the salted sha-1 instead of a password like a normal logon.

The best bet is to limit bad logon attempts to some reasonable number - 25 for example, and then time the user out for a minute or two. And if the cumulative bady logon attempts hits 250 within 24 hours, shut the account access down and email the owner.

It looks like you can use msdb.dbo.sysjobactivity, checking for a record with a non-null start_execution_date and a null stop_execution_date, meaning the job was started, but has not yet completed.

This would give you currently running jobs:

SELECT sj.name
   , sja.*
FROM msdb.dbo.sysjobactivity AS sja
INNER JOIN msdb.dbo.sysjobs AS sj ON sja.job_id = sj.job_id
WHERE sja.start_execution_date IS NOT NULL
   AND sja.stop_execution_date IS NULL

What about something like this:

['focusout','keydown'].forEach( function(evt) {
        self.slave.addEventListener(evt, function(event) {
            // Here `this` is for the slave, i.e. `self.slave`
            if ((event.type === 'keydown' && event.which === 27) || event.type === 'focusout') {
                this.style.display = 'none';
                this.parentNode.querySelector('.master').style.display = '';
                this.parentNode.querySelector('.master').value = this.value;
                console.log('out');
            }
        }, false);
});

// The above is replacement of:
 /*   self.slave.addEventListener("focusout", function(event) { })
      self.slave.addEventListener("keydown", function(event) {
         if (event.which === 27) {  // Esc
            }
      })
*/

If the columns to be reordered have recently been created and are empty, then the columns can be deleted and re-added in the correct order.

This happened to me, extending a database manually to add new functionality, and I had missed a column out, and when I added it, the sequence was incorrect.

After finding no adequate solution here I simply corrected the table using the following kind of commands.

ALTER TABLE  tablename  DROP COLUMN  columnname; 
ALTER TABLE  tablename  ADD columnname columntype;

Note: only do this if you don't have data in the columns you are dropping.

People have said that column order does not matter. I regularly use SQL Server Management Studio "generate scripts" to create a text version of a database's schema. To effectively version control these scripts (git) and to compare them (WinMerge), it is imperative that the output from compatible databases is the same, and the differences highlighted are genuine database differences.

Column order does matter; but just to some people, not to everyone!

Your code looks fine, but there are a couple of things to be aware of:

Post::find($id); acts upon the primary key, if you have set your primary key in your model to something other than id by doing:

protected  $primaryKey = 'slug';

then find will search by that key instead.

Laravel also expects the id to be an integer, if you are using something other than an integer (such as a string) you need to set the incrementing property on your model to false:

public $incrementing = false;

Use any examples that don't insert each element one at a time, one insertion is most efficient

 $('.element').html( '<span>' + array.join('</span><span>')+'</span>');

Using 64bit version of Git on Windows, just add the self signed CA certificate into these files :

• C:\Program Files\Git\mingw64\ssl\certs\ca-bundle.crt
• C:\Program Files\Git\mingw64\ssl\certs\ca-bundle.trust.crt

If it is just a server self signed certificate add it into

• C:\Program Files\Git\mingw64\ssl\cert.pem

const string strCmdText = "/C command1&command2";
Process.Start("CMD.exe", strCmdText);

I guess the dirtiest solution is this:

list(eval('0, 0, 0, 11, 0, 0, 0, 11'))

I don't expose any endpoints and start (with nohup in background and without out files created through nohup) and stop with shell script(with KILL PID gracefully and force kill if app is still running after 3 mins). I just create executable jar and use PID file writer to write PID file and store Jar and Pid in folder with same name as of application name and shell scripts also have same name with start and stop in the end. I call these stop script and start script via jenkins pipeline also. No issues so far. Perfectly working for 8 applications(Very generic scripts and easy to apply for any app).
