if you already have that hidden input :

function product(a, b) {
   return a * b;
}
function setInputValue(input_id, val) {
    document.getElementById(input_id).setAttribute('value', val);
}

if not, you can create one, add it to the body and then set it's value :

function addInput(val) {
    var input = document.createElement('input');
    input.setAttribute('type', 'hidden');
    input.setAttribute('value', val);
    document.body.appendChild(input);
}

And then you can use(depending on the case) :

addInput(product(2, 3)); // if you want to create the input
// or
setInputValue('input_id', product(2, 3)); 

You are not allowed to have div tags between tr tags. You have to look for some other strategies like creating a CSS class with display: none and adding it to concerning rows or adding inline style display: none to concerning rows.

.hidden
{
  display:none;
}

<table>
  <tr><td>I am visible</td><tr>
  <tr class="hidden"><td>I am hidden using CSS class</td><tr>
  <tr class="hidden"><td>I am hidden using CSS class</td><tr>
  <tr class="hidden"><td>I am hidden using CSS class</td><tr>
  <tr class="hidden"><td>I am hidden using CSS class</td><tr>
</table>

or

<table>
  <tr><td>I am visible</td><tr>
  <tr style="display:none"><td>I am hidden using inline style</td><tr>
  <tr style="display:none"><td>I am hidden using inline style</td><tr>
  <tr style="display:none"><td>I am hidden using inline style</td><tr>
</table>

This is designed for use when you have a shell script build step. Use only the first two lines to get the file name.

You can get the console log file (using bash magic) for the current build from a shell script this way and check it for some error string, failing the job if found:

logFilename=${JENKINS_HOME}/${JOB_URL:${#JENKINS_URL}}
logFilename=${logFilename//job\//jobs\/}builds/${BUILD_NUMBER}/log

grep "**Failure**" ${logFilename} ; exitCode=$?
[[ $exitCode -ne 1 ]] && exit 1

You have to build the file name by taking the JOB_URL, stripping off the leading host name part, adding in the path to JENKINS_HOME, replacing "/job/" to "/jobs/" to handle all nested folders, adding the current build number and the file name.

The grep returns 0 if the string is found and 2 if there is a file error. So a 1 means it found the error indication string. That makes the build fail.

How about some lovely CSS3?

li { background: green; }
li:nth-child(odd) { background: red; }

This /[^a-z]/g solves the problem.

function pangram(str) {
    let regExp = /[^a-z]/g;
    let letters = str.toLowerCase().replace(regExp, '');
    document.getElementById('letters').innerHTML = letters;
}
pangram('GHV 2@# %hfr efg uor7 489(*&^% knt lhtkjj ngnm!@#$%^&*()_');

<h4 id="letters"></h4>

Object Model is concerned with the following three concepts Data Abstraction Encapsulation Inheritance The relational model used the basic concept of a relation or table. Object-relational mapping (OR mapping) products integrate object programming language capabilities with relational databases.

First, let's make some test data:

create table client (client_id integer not null primary key auto_increment,
                     name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
                        client_id integer references client.id,
                        cash decimal(10,2),
                        stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
                                                       (1, 10.11, 23.22),
                                                       (2, 30.30, 40.40),
                                                       (2, 40.40, 50.50);

If you didn't need the portfolio ID, it would be easy:

select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id

+-----------+----------+--------------------+
| client_id | name     | max(cash + stocks) |
+-----------+----------+--------------------+
|         1 | John Doe |              33.33 | 
|         2 | Jane Doe |              90.90 | 
+-----------+----------+--------------------+

Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:

select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id

+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
|         1 |    33.33 | 
|         2 |    90.90 | 
+-----------+----------+

Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:

 select portfolio_id, cash + stocks from portfolio 
 join (select client_id, max(cash + stocks) as maxtotal 
       from portfolio
       group by client_id) as maxima
 using (client_id)
 where cash + stocks = maxtotal

+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
|            5 |         33.33 | 
|            6 |         33.33 | 
|            8 |         90.90 | 
+--------------+---------------+

Finally, we can join to the client table (as you did) in order to include the name of each client:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         1 | John Doe |            6 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

From man diff, you can use -y to do side-by-side.

-y, --side-by-side
       output in two columns

Hence, say:

diff -y /tmp/test1  /tmp/test2

Test

$ cat a                $ cat b
hello                  hello
my name                my name
is me                  is you

Let's compare them:

$ diff -y a b
hello                                                           hello
my name                                                         my name
is me                                                         | is you

Did you set an appropriate security group for the instance? I.e. one that allows access from your network to port 22 on the instance. (By default all traffic is disallowed.)

Update: Ok, not a security group issue. But does the problem persist if you launch up another instance from the same AMI and try to access that? Maybe this particular EC2 instance just randomly failed somehow – it is only matter of time that something like that happens. (Recommended reading: Architecting for the Cloud: Best Practices (PDF), a paper by Jinesh Varia who is a web services evangelist at Amazon. See especially the section titled "Design for failure and nothing will fail".)

Use Python shell to find out the path of Django:

>>> import django
>>> django
<module 'django' from '/usr/local/lib/python2.7/dist-packages/django/__init__.pyc'>

Then remove it manually:

sudo rm -rf /usr/local/lib/python2.7/dist-packages/django/

You need to create a C API for exposing the functionality of your C++ code. Basically, you will need to write C++ code that is declared extern "C" and that has a pure C API (not using classes, for example) that wraps the C++ library. Then you use the pure C wrapper library that you've created.

Your C API can optionally follow an object-oriented style, even though C is not object-oriented. Ex:

 // *.h file
 // ...
 #ifdef __cplusplus
 #define EXTERNC extern "C"
 #else
 #define EXTERNC
 #endif

 typedef void* mylibrary_mytype_t;

 EXTERNC mylibrary_mytype_t mylibrary_mytype_init();
 EXTERNC void mylibrary_mytype_destroy(mylibrary_mytype_t mytype);
 EXTERNC void mylibrary_mytype_doit(mylibrary_mytype_t self, int param);

 #undef EXTERNC
 // ...


 // *.cpp file
 mylibrary_mytype_t mylibrary_mytype_init() {
   return new MyType;
 }

 void mylibrary_mytype_destroy(mylibrary_mytype_t untyped_ptr) {
    MyType* typed_ptr = static_cast<MyType*>(untyped_ptr);
    delete typed_ptr;
 }

 void mylibrary_mytype_doit(mylibrary_mytype_t untyped_self, int param) {
    MyType* typed_self = static_cast<MyType*>(untyped_self);
    typed_self->doIt(param);
 }

alter table table_name add primary key (col_name1, col_name2);

Experimenting, I found a solution using <div…/> but an obvious solution is to place your own anchor point in the page wherever you like, thus:

<a name="abcde">

before and

</a>

after the line you want to "link" to. Then a markdown link like:

[link text](#abcde)

anywhere in the document takes you there.

The <div…/> solution inserts a "dummy" division just to add the id property, and this is potentially disruptive to the page structure, but the <a name="abcde"/> solution ought to be quite innocuous.

(PS: It might be OK to put the anchor in the line you wish to link to, as follows:

## <a name="head1">Heading One</a>

but this depends on how Markdown treats this. I note, for example, the Stack Overflow answer formatter is happy with this!)

I think that the most elegant way to do it is to implement custom Flash Scope in Spring MVC.

the main idea for the flash scope is to store data from one controller till next redirect in second controller

Please refer to my answer on the custom scope question:

Spring MVC custom scope bean

The only thing that is missing in this code is the following xml configuration:

<bean id="flashScopeInterceptor" class="com.vanilla.springMVC.scope.FlashScopeInterceptor" />
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
  <property name="interceptors">
    <list><ref bean="flashScopeInterceptor"/></list>
  </property>
</bean>

You can use COPY. You need to specify the directory explicitly. It won't be created by itself

COPY go /usr/local/go

Reference: Docker CP reference

Process p = Runtime.getRuntime().exec( 
  new String[]{"cmd", "/C", "orgreg.bat"},
  null, 
  new File("D://TEST//home//libs//"));

tested with jdk1.5 and jdk1.6

This was working fine for me, hope it helps others too. to get this i have struggled more days. :(

You can also use sed's change line to accomplish this:

sed -i "/aaa=/c\aaa=xxx" your_file_here

This will go through and find any lines that pass the aaa= test, which means that the line contains the letters aaa=. Then it replaces the entire line with aaa=xxx. You can add a ^ at the beginning of the test to make sure you only get the lines that start with aaa= but that's up to you.

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

do you have sklearn? if not, do the following:

2019 Update

This updates the answers with the latest Fetch API and doesn't need jQuery.

Disclaimer: doesn't work on IE, Opera Mini and older browsers. See caniuse.

Basic Fetch

It could be as simple as:

  fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
                .then(response => console.log(response.text()))

Fetch with Error Handling

After adding error handling, it could look like:

fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
            .then(response => {
                if (response.ok) return response;
                else throw Error(`Server returned ${response.status}: ${response.statusText}`)
            })
            .then(response => console.log(response.text()))
            .catch(err => {
                alert(err);
            });

PHP Code

This is the server-side code in upload.php.

<?php    
    // gets entire POST body
    $data = file_get_contents('php://input');
    // write the data out to the file
    $fp = fopen("path/to/file", "wb");

    fwrite($fp, $data);
    fclose($fp);
?>

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

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

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

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

If you want to be able to show / hide singular divs and / or groups of divs with less code, just apply several classes to them, to insert them into groups if needed.

Example :

.group1 {}
.group2 {}
.group3 {}

<div class="group3"></div>
<div class="group1 group2"></div>
<div class="group1 group3 group2"></div>

Then you just need to use an identifier to link the action to he target, and with 5,6 lines of jquery code you have everything you need.

After taking a closer look at the Mongoose API with the information provided by Rodolphe, I figured out this solution:

MyModel.find(query, fields, { skip: 10, limit: 5 }, function(err, results) { ... });

Check the local.properties file in your Studio Project. Chances are that the property sdk.dir points to the wrong folder if you had set/configured a previous android sdk from pre-studio era. This was the solution in my case.

If you install PyQt4 on Windows, files wind up here by default:

C:\Python27\Lib\site-packages\PyQt4*.*

but it also leaves a file here:

C:\Python27\Lib\site-packages\sip.pyd

If you copy the both the sip.pyd and PyQt4 folder into your virtualenv things will work fine.

For example:

mkdir c:\code
cd c:\code
virtualenv BACKUP
cd c:\code\BACKUP\scripts
activate

Then with windows explorer copy from C:\Python27\Lib\site-packages the file (sip.pyd) and folder (PyQt4) mentioned above to C:\code\BACKUP\Lib\site-packages\

Then back at CLI:

cd ..                 
(c:\code\BACKUP)
python backup.py

The problem with trying to launch a script which calls PyQt4 from within virtualenv is that the virtualenv does not have PyQt4 installed and it doesn't know how to reference the default installation described above. But follow these steps to copy PyQt4 into your virtualenv and things should work great.

You can use getter function or get accessor to act as watch on angular 2.

See demo here.

import {Component} from 'angular2/core';

@Component({
  // Declare the tag name in index.html to where the component attaches
  selector: 'hello-world',

  // Location of the template for this component
  template: `
  <button (click)="OnPushArray1()">Push 1</button>
  <div>
    I'm array 1 {{ array1 | json }}
  </div>
  <button (click)="OnPushArray2()">Push 2</button>
  <div>
    I'm array 2 {{ array2 | json }}
  </div>
  I'm concatenated {{ concatenatedArray | json }}
  <div>
    I'm length of two arrays {{ arrayLength | json }}
  </div>`
})
export class HelloWorld {
    array1: any[] = [];
    array2: any[] = [];

    get concatenatedArray(): any[] {
      return this.array1.concat(this.array2);
    }

    get arrayLength(): number {
      return this.concatenatedArray.length;
    }

    OnPushArray1() {
        this.array1.push(this.array1.length);
    }

    OnPushArray2() {
        this.array2.push(this.array2.length);
    }
}

I assume your column type is STRING (CHAR, VARCHAR, etc) and sorting procedure is sorting it as a string. What you need to do is to convert value into numeric value. How to do it will depend on SQL system you use.

Cast the datetime to a date, then GROUP BY using this syntax:

SELECT SUM(foo), DATE(mydate) FROM a_table GROUP BY DATE(a_table.mydate);

Or you can GROUP BY the alias as @orlandu63 suggested:

SELECT SUM(foo), DATE(mydate) DateOnly FROM a_table GROUP BY DateOnly;

Though I don't think it'll make any difference to performance, it is a little clearer.

Something else to consider when this type of error is encountered:

I was running into this error message and found this post helpful. Turns out in my case I had overridden an __init__() where there was object inheritance.

The inherited example is rather long, so I'll skip to a more simple example that doesn't use inheritance:

class MyBadInitClass:
    def ___init__(self, name):
        self.name = name

    def name_foo(self, arg):
        print(self)
        print(arg)
        print("My name is", self.name)


class MyNewClass:
    def new_foo(self, arg):
        print(self)
        print(arg)


my_new_object = MyNewClass()
my_new_object.new_foo("NewFoo")
my_bad_init_object = MyBadInitClass(name="Test Name")
my_bad_init_object.name_foo("name foo")

Result is:

<__main__.MyNewClass object at 0x033C48D0>
NewFoo
Traceback (most recent call last):
  File "C:/Users/Orange/PycharmProjects/Chapter9/bad_init_example.py", line 41, in <module>
    my_bad_init_object = MyBadInitClass(name="Test Name")
TypeError: object() takes no parameters

PyCharm didn't catch this typo. Nor did Notepad++ (other editors/IDE's might).

Granted, this is a "takes no parameters" TypeError, it isn't much different than "got two" when expecting one, in terms of object initialization in Python.

Addressing the topic: An overloading initializer will be used if syntactically correct, but if not it will be ignored and the built-in used instead. The object won't expect/handle this and the error is thrown.

In the case of the sytax error: The fix is simple, just edit the custom init statement:

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

Plenty of good ideas on this thread. I have a lot of popups in my page for handling user input. What I use, is a combination of disabling the mousewheel and hiding the scrollbar:

this.disableScrollFn= function(e) { 
    e.preventDefault(); e.stopPropagation() 
};
document.body.style.overflow = 'hidden';
$('body').on('mousewheel', this.disableScrollFn);

Advantage of this is we stop the user from scrolling in any possible way, and without having to change css position and top properties. I'm not concerened about touch events, since touch outside would close the popup.

To disable this, upon closing the popup I do the following.

document.body.style.overflow = 'auto';
$('body').off('mousewheel', this.disableScrollFn);

Note, I store a reference to my disableScrollFn on the existing object (in my case a PopupViewModel), for that gets triggered upon closing the popup to have access to disableScrollFn.

You can simplify Joe Kington's code using the axparameter of figure.colorbar() with a list of axes. From the documentation:

ax

None | parent axes object(s) from which space for a new colorbar axes will be stolen. If a list of axes is given they will all be resized to make room for the colorbar axes.

import numpy as np
import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=2, ncols=2)
for ax in axes.flat:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

fig.colorbar(im, ax=axes.ravel().tolist())

plt.show()

skip` didn't work, so my workaround is

$LinesCount = $(get-content $file).Count
get-content $file |
    select -Last $($LinesCount-1) | 
    set-content "$file-temp"
move "$file-temp" $file -Force

C# represents a character in UTF-16 coding rather than ASCII. Therefore converting a integer to character do not make any difference for A-Z and a-z. But I was working with ASCII Codes besides alphabets and number which did not work for me as system uses UTF-16 code. Therefore I browsed UTF-16 code for all UTF-16 character. Here is the module :

void utfchars()
{
 int i, a, b, x;
 ConsoleKeyInfo z;
  do
  {
   a = 0; b = 0; Console.Clear();
    for (i = 1; i <= 10000; i++)
    {
     if (b == 20)
     {
      b = 0;
      a = a + 1;
     }
    Console.SetCursorPosition((a * 15) + 1, b + 1);
    Console.Write("{0} == {1}", i, (char)i);

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.

Steps to resolve:

1. Open the Run window:

   Press windows+R

2. Open registry window:

   Type regedit and enter.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:

6. Create a new subkey of 1.8.

7. For 1.8 create a String Key with name JavaHome with the value of JRE home:

          <td><ul>
            <li><a href="#">Home</a></li>
            <li><a href="#">Projects</a></li>
            <li><a href="#">About</a></li>

While configuring idea plugin in gradle, you should define output directories as follows.

idea{
    module{
        inheritOutputDirs = false
        outputDir = compileJava.destinationDir
        testOutputDir = compileTestJava.destinationDir
    }
}

For compare hashed password with the plain text password string you can use the PHP password_verify

if(password_verify('1234567', $crypt_password_string)) {
    // in case if "$crypt_password_string" actually hides "1234567"
}

A memory heap is a location in memory where memory may be allocated at random access.
Unlike the stack where memory is allocated and released in a very defined order, individual data elements allocated on the heap are typically released in ways which is asynchronous from one another. Any such data element is freed when the program explicitly releases the corresponding pointer, and this may result in a fragmented heap. In opposition only data at the top (or the bottom, depending on the way the stack works) may be released, resulting in data element being freed in the reverse order they were allocated.

Here is a coffeescript version that worked for me.

$(document).on 'hidden.bs.modal', (e) ->
  target = $(e.target)
  target.removeData('bs.modal').find(".modal-content").html('')

Why don't you do:

$("#radio1, #radio2, #radio3, #radio4").checked = false;

The same way how an int can be positive or negative. There is no difference. Actually on many platforms unqualified char is signed.

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

If I am not mistaken, it will be onunload event.

"Occurs when the application is about to be unloaded." - MSDN

By using Reflector, you can see, that Contains is implemented using IndexOf. Here's the implementation.

public bool Contains(string value)
{
   return (this.IndexOf(value, StringComparison.Ordinal) >= 0);
}

So Contains is likely a wee bit slower than calling IndexOf directly, but I doubt that it will have any significance for the actual performance.

You want the zip function.

for (f,b) in zip(foo, bar):
    print "f: ", f ,"; b: ", b

Click on the project name (Right to the Run button). Three options will appear.

1. Edit scheme
2. New scheme
3. Manage scheme

You can click on "New scheme" and then click on "OK" in popup window.

You will have simulators list back.

You can do a column transformation by using apply

Define a clean function to remove the dollar and commas and convert your data to float.

def clean(x):
    x = x.replace("$", "").replace(",", "").replace(" ", "")
    return float(x)

Next, call it on your column like this.

data['Revenue'] = data['Revenue'].apply(clean)

In Perl 6 there is, the say function

You can issue the INFO command, which returns information and statistics about the server. See here for an example output.

For Active Directory users, an alternative way to do this would be -- assuming all your groups are stored in OU=Groups,DC=CorpDir,DC=QA,DC=CorpName -- to use the query (&(objectCategory=group)(CN=GroupCN)). This will work well for all groups with less than 1500 members. If you want to list all members of a large AD group, the same query will work, but you'll have to use ranged retrieval to fetch all the members, 1500 records at a time.

The key to performing ranged retrievals is to specify the range in the attributes using this syntax: attribute;range=low-high. So to fetch all members of an AD Group with 3000 members, first run the above query asking for the member;range=0-1499 attribute to be returned, then for the member;range=1500-2999 attribute.

There may be a little problem with code from Vishnu's answer. If there is no digits in the string it will return ValueError. Here is my suggestion avoid this:

>>> digit = lambda x: int(filter(str.isdigit, x) or 0)
>>> digit('3158 reviews')
3158
>>> digit('reviews')
0

As DigitalRoss pointed out, the trailing backslash is not necessary when the line woud end in |. And you can put comments on a line following a |:

I would like to expand on the Windows solution. Using IDLE with Python 2.7.5, When I run this code from file Expts.py:

import subprocess
r = subprocess.check_output('cmd.exe dir',shell=False) 
print r

...in the Python Shell, I ONLY get the output corresponding to "cmd.exe"; the "dir" part is ignored. HOWEVER, when I add a switch such as /K or /C ...

import subprocess
r = subprocess.check_output('cmd.exe /K dir',shell=False) 
print r

...then in the Python Shell, I get all that I expect including the directory listing. Woohoo !

Now, if I try any of those same things in DOS Python command window, without the switch, or with the /K switch, it appears to make the window hang because it is running a subprocess cmd.exe and it awaiting further input - type 'exit' then hit [enter] to release. But with the /K switch it works perfectly and returns you to the python prompt. Allrightee then.

Went a step further...I thought this was cool...When I instead do this in Expts.py:

import subprocess
r = subprocess.call("cmd.exe dir",shell=False) 
print r

...a new DOS window pops open and remains there displaying only the results of "cmd.exe" not of "dir". When I add the /C switch, the DOS window opens and closes very fast before I can see anything (as expected, because /C terminates when done). When I instead add the /K switch, the DOS window pops open and remain, AND I get all the output I expect including the directory listing.

If I try the same thing (subprocess.call instead of subprocess.check_output) from a DOS Python command window; all output is within the same window, there are no popup windows. Without the switch, again the "dir" part is ignored, AND the prompt changes from the python prompt to the DOS prompt (since a cmd.exe subprocess is running in python; again type 'exit' and you will revert to the python prompt). Adding the /K switch prints out the directory listing and changes the prompt from python to DOS since /K does not terminate the subprocess. Changing the switch to /C gives us all the output expected AND returns to the python prompt since the subprocess terminates in accordance with /C.

Sorry for the long-winded response, but I am frustrated on this board with the many terse 'answers' which at best don't work (seems because they are not tested - like Eduard F's response above mine which is missing the switch) or worse, are so terse that they don't help much at all (e.g., 'try subprocess instead of os.system' ... yeah, OK, now what ??). In contrast, I have provided solutions which I tested, and showed how there are subtle differences between them. Took a lot of time but... Hope this helps.

Solution (not the best, but still working for some cases) for non-dinamic text with fixed width.Usefull for situations when there are a little space to "stretch" text to the end of the penultimate line. Make some symbols in the end of the paragraph (experiment with their length) and hide it; apply to the paragraph absolute position or just correct free space with padding/marging.

Good compabitity/crossbrowser way for center-justifying text.

Example (paragraph before):

.paragraph {_x000D_
    width:455px;_x000D_
    text-align:justify;_x000D_
}_x000D_
_x000D_
.center{_x000D_
  display:block;_x000D_
  text-align:center;_x000D_
  margin-top:-17px;_x000D_
}

<div class="paragraph">Cras justo odio, dapibus ac facilisis in, egestas eget quam. Nullam id dolor id nibh ultricies vehicula ut id elit. Etiam porta sem malesuada magna mollis euismod. Nullam id dolor id nibh ultricies vehicula ut id elit. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla vitae elit libero, a pharetra augue. Praesent commodo cursus magna,<br><center>vel scelerisque nisl consectetur et.</center></div>

And after the fix:

.paragraph {_x000D_
    width:455px;_x000D_
    text-align:justify;_x000D_
    position:relative;_x000D_
}_x000D_
.center{_x000D_
  display:block;_x000D_
  text-align:center;_x000D_
  margin-top:-17px;_x000D_
}_x000D_
.paragraph b{_x000D_
  opacity:0;_x000D_
_x000D_
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";_x000D_
filter: alpha(opacity=0);_x000D_
-moz-opacity: 0;_x000D_
-khtml-opacity: 0;_x000D_
}

<div class="paragraph">Cras justo odio, dapibus ac facilisis in, egestas eget quam. Nullam id dolor id nibh ultricies vehicula ut id elit. Etiam porta sem malesuada magna mollis euismod. Nullam id dolor id nibh ultricies vehicula ut id elit. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla vitae elit libero, a pharetra augue.

Transaction is an indivisible unit of data processing -All transactions must have the ACID properties:

ie:Atomicity,Consistency,Isolation and Durable Transaction is all or nothing but not intermidiate (it means if you transfer your money from one account to another account,one account have to lose that much and other one have to gain that amount,but if you transfer money from one account and another account is still empty that will be not a transaction)

A PendingIntent is a token that you give to another application (e.g. Notification Manager, Alarm Manager or other 3rd party applications), which allows this other application to use the permissions of your application to execute a predefined piece of code. To perform a broadcast via a pending intent so get a PendingIntent via PendingIntent.getBroadcast(). To perform an activity via an pending intent you receive the activity via PendingIntent.getActivity().

Some code I've worked with in the past used global variables just to avoid passing too many parameters around.

Please don't do that!

(Usually.)

Just FYI, if you are using Java 11+, there is an exception to this rule: if you run your java file directly (without compilation). In this mode, there is no restriction on a single public class per file. However, the class with the main method must be the first one in the file.

I find it easier to push or append arrays and then flatten them in place, like so:

somearray = ["some", "thing"]
anotherarray = ["another", "thing"]
somearray.push anotherarray # => ["some", "thing", ["another", "thing"]]
#or
somearray << anotherarray # => ["some", "thing", ["another", "thing"]]
somearray.flatten!  # => ["some", "thing", "another", "thing"]
somearray # => ["some", "thing", "another", "thing"]

Hash functions for algorithmic use have usually 2 goals, first they have to be fast, second they have to evenly distibute the values across the possible numbers. The hash function also required to give the all same number for the same input value.

if your values are strings, here are some examples for bad hash functions:

1. string[0] - the ASCII characters a-Z are way more often then others
2. string.lengh() - the most probable value is 1

Good hash functions tries to use every bit of the input while keeping the calculation time minimal. If you only need some hash code, try to multiply the bytes with prime numbers, and sum them.

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

Try this:

var jIsHasKids = $('#chkIsHasKids').attr('checked');
jIsHasKids = jIsHasKids.toString().toLowerCase();
//OR
jIsHasKids = jIsHasKids.val().toLowerCase();

I was getting this error because of the new Google Universal Analytics code, particularly caused by using the Remarketing lists on Analytics.

Here's how I fixed it.
1) Log into Google Analytics
2) Click "Admin" in top menu
3) In "Property" column, click "Property Settings"
4) Make sure "Enable Display Advertiser Features" is "On"
5) Click "Save" at bottom
6) Click ".js Tracking Info" in left menu
7) Click "Tracking Code"
8) Update your website's tracking code


When you run the debugger again, hopefully it will be taken care of.

for your example:

{'profiles': [{'name':'john', 'age': 44}, {'name':'Alex','age':11}]}

you will have to do something of this effect:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

this returns the array object.

Then iterating will be as follows:

    int size = the_json_array.length();
    ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
    for (int i = 0; i < size; i++) {
        JSONObject another_json_object = the_json_array.getJSONObject(i);
            //Blah blah blah...
            arrays.add(another_json_object);
    }

//Finally
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

//The end...

You will have to determine if the data is an array (simply checking that charAt(0) starts with [ character).

Hope this helps.

Here goes what O'reilly Enterprise JavaBeans, 3.0 says

JDBC has special types for these very large objects. The java.sql.Blob type represents binary data, and java.sql.Clob represents character data.

Here goes PostgreSQLDialect source code

public PostgreSQLDialect() {
    super();
    ...
    registerColumnType(Types.VARBINARY, "bytea");
    /**
      * Notice it maps java.sql.Types.BLOB as oid
      */
    registerColumnType(Types.BLOB, "oid");
}

So what you can do

Override PostgreSQLDialect as follows

public class CustomPostgreSQLDialect extends PostgreSQLDialect {

    public CustomPostgreSQLDialect() {
        super();

        registerColumnType(Types.BLOB, "bytea");
    }
}

Now just define your custom dialect

<property name="hibernate.dialect" value="br.com.ar.dialect.CustomPostgreSQLDialect"/>

And use your portable JPA @Lob annotation

@Lob
public byte[] getValueBuffer() {

UPDATE

Here has been extracted here

I have an application running in hibernate 3.3.2 and the applications works fine, with all blob fields using oid (byte[] in java)

...

Migrating to hibernate 3.5 all blob fields not work anymore, and the server log shows: ERROR org.hibernate.util.JDBCExceptionReporter - ERROR: column is of type oid but expression is of type bytea

which can be explained here

This generaly is not bug in PG JDBC, but change of default implementation of Hibernate in 3.5 version. In my situation setting compatible property on connection did not helped.

...

Much more this what I saw in 3.5 - beta 2, and i do not know if this was fixed is Hibernate - without @Type annotation - will auto-create column of type oid, but will try to read this as bytea

Interesting is because when he maps Types.BOLB as bytea (See CustomPostgreSQLDialect) He get

Could not execute JDBC batch update

when inserting or updating

There are two useful tools which will generate Java code (rough but good enough) from an unknown APK file.

1. Download dex2jar tool from dex2jar.

2. Use the tool to convert the APK file to JAR:

   $ d2j-dex2jar.bat demo.apk
   dex2jar demo.apk -> ./demo-dex2jar.jar
   

3. Once the JAR file is generated, use JD-GUI to open the JAR file. You will see the Java files.

The output will be similar to:

MM/DD/YYYY format

If you have the MM/DD/YYYY format which is default for JavaScript, you can simply pass your string to Date(string) constructor. It will parse it for you.

var dateString = "10/23/2015"; // Oct 23_x000D_
_x000D_
var dateObject = new Date(dateString);_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

DD/MM/YYYY format - manually

If you work with this format, then you can split the date in order to get day, month and year separately and then use it in another constructor - Date(year, month, day):

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateParts = dateString.split("/");_x000D_
_x000D_
// month is 0-based, that's why we need dataParts[1] - 1_x000D_
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]); _x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

For more information, you can read article about Date at Mozilla Developer Network.

DD/MM/YYYY - using moment.js library

Alternatively, you can use moment.js library, which is probably the most popular library to parse and operate with date and time in JavaScript:

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateMomentObject = moment(dateString, "DD/MM/YYYY"); // 1st argument - string, 2nd argument - format_x000D_
var dateObject = dateMomentObject.toDate(); // convert moment.js object to Date object_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

<script src="https://momentjs.com/downloads/moment.min.js"></script>

In all three examples dateObject variable contains an object of type Date, which represents a moment in time and can be further converted to any string format.

<script type="text/javascript">
  function f1(mHref)
  {
    document.getElementById("abc").href=mHref; 
  }
</script>

<a href="" id="abc">jhg</a>
<button onclick="f1("dynamicHref")">Change HREF</button>

Just give the dynamic HREF in Paramters

Visual Studio Code is integrated with a command prompt / terminal, hence it will be handy when there is switching between IDE and terminal / command prompt required, for example: connecting to Linux.

The dev console will log errors thrown by the app script, so you can just throw an error to get it logged as a normal console.log. It will stop execution, but it might still be useful for step by step debugging.

throw Error('hello world!');

will show up in the console similarly to console.log('hello world')

You can run the cd and the executable in a subshell by enclosing the command line in a pair of parentheses:

(cd SOME_PATH && exec_some_command)

Demo:

$ pwd
/home/abhijit
$ (cd /tmp && pwd)  # directory changed in the subshell
/tmp 
$ pwd               # parent shell's pwd is still the same
/home/abhijit

I encountered this problem too. If you want the activity that handles permissions not in the history/recents, then you will be tempted to change your AndroidManifest.xml entry.

If you set the activity that you call requestPermissions or AppCompatActivity.requestPermissions with

android:noHistory="true"
android:excludeFromRecents="true"

in your AndroidManifest.xml then onRequestPermissionsResult() will not be called. This is true if your Activity is derived from Activity or AppCompatActivity.

This can be fixed by removing both flags from 'AndroidManifest.xml' and finishing your activity with finishAndRemoveTask() instead.

There are online tools that simplify this process of sharing, for example https://abbashare.com or https://diawi.com Create an ipa file from xcode with adhoc or inhouse profile, and upload this file on these site. I prefer abbashare because save file on your dropbox and you can delete it whenever you want

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

Angular-Paging

is a wonderful choice

A directive to aid in paging large datasets while requiring the bare minimum of actual paging information. We are very dependant on the server for "filtering" results in this paging scheme. The central idea being we only want to hold the active "page" of items - rather than holding the entire list of items in memory and paging on the client-side.

None of these answers worked for me, I had to do the following:

1. Start Menu > type 'Internet Options'.
2. Select Local intranet zone on the Security tab then click the Sites button
3. Click Advanced button
4. Enter file://[computer name]
5. Make sure 'Require server verification...' is unticked

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings

Update: this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

If you're using Weebly, start by viewing the published site and right-clicking the image to Copy Image Address. Then in Weebly, go to Edit Site, Pages, click the page you wish to use, SEO Settings, under Header Code enter the code from Shef's answer:

<meta property="og:image" content="/uploads/..." />

just replacing /uploads/... with the copied image address. Click Publish to apply the change.

You can skip the part of Shef's answer about namespace, because that's already set by default in Weebly.

I believe the browser is looking for those assets FROM the root of the webserver. This is difficult because it is easy to start developing on your machine WITHOUT actually using a webserver ( just by loading local files through your browser)

You could start by packaging your html and css/js together?

a directory structure something like:

-yourapp
  - index.html
  - assets
    - css
    - js
      - myPage.js

Then your script tag (from index.html) could look like

<script src="assets/js/myPage.js"></script>

An added benifit of packaging your html and assets in one directory is that you can copy the directory and give it to someone else or put it on another machine and it will work great.

In Laravel 6.0 make:auth no longer exists. Read more here

A- Shorthand:

Update Nov 18th: Taylor just released Laravel Installer 2.3.0 added a new "--auth" flag to create a new project with the authentication scaffolding installed!

To update laravel installer read here

It means we can do:

laravel new project --auth

cd project

php artisan migrate

npm install
npm run dev

Which is a shorthand of commands in the Section B. Also read more here

B - Details:

Follow these three steps

Step 1 - First do this:

laravel new project

cd project

composer require laravel/ui --dev

Note: Laravel UI Composer package is a new first-party package that extracts the UI portion of a Laravel project ( frontend scaffolding typically provided with previous releases of Laravel ) into a separate laravel/ui package. The separate package enables the Laravel team to update, develop and version UI scaffolding package separately from the primary framework and the main Laravel codebase.

Step 2 - Then do this:

php artisan ui bootstrap --auth
php artisan migrate

or

php artisan ui vue --auth
php artisan migrate

instead of

php artisan make:auth  ( which works for Laravel 5.8 and older versions )

More Options here

php artisan ui:auth

The above command will generate only the auth routes, a HomeController, auth views, and a app.blade.php layout file.

You can also generate the views only with:

php artisan ui:auth --views

The console command will prompt you to confirm overwriting auth files if you've already run the command before.

// Generate basic scaffolding...
php artisan ui vue
php artisan ui react

and also:

// Generate login / registration scaffolding...
php artisan ui vue --auth
php artisan ui react --auth

To see differences read this article

Step 3 - Then you need to do:

npm install
npm run dev

I think the $() syntax is easier to read...

variable=$(ps -ef | grep "port 10 -" | grep -v "grep port 10 -"| awk '{printf "%s", $12}')

But the real issue is probably that $12 should not be qouted with ""

Edited since the question was changed, This returns valid data, but it is not clear what the expected output of ps -ef is and what is expected in variable.

To view open ports, use the following command.

firewall-cmd --list-ports

We use the following to see services whose ports are open.

firewall-cmd --list-services

We use the following to see services whose ports are open and see open ports

firewall-cmd --list-all

To add a service to the firewall, we use the following command, in which case the service will use any port to open in the firewall.

firewall-cmd --add-services=ntp 

For this service to be permanently open we use the following command.

firewall-cmd —add-service=ntp --permanent 

To add a port, use the following command

firewall-cmd --add-port=132/tcp  --permanent

To run the firewall must be reloaded using the following command.

firewall-cmd --reload

I've got the same problem in Docker.

In Docker I keep trained LightGBM model + Flask serving requests. As HTTP server I used gunicorn 19.9.0. When I run my code locally on my Mac laptop everything worked just perfect, but when I ran the app in Docker my POST JSON requests were freezing for some time, then gunicorn worker had been failing with [CRITICAL] WORKER TIMEOUT exception.

I tried tons of different approaches, but the only one solved my issue was adding worker_class=gthread.

Here is my complete config:

import multiprocessing

workers = multiprocessing.cpu_count() * 2 + 1
accesslog = "-" # STDOUT
access_log_format = '%(h)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(q)s" "%(D)s"'
bind = "0.0.0.0:5000"
keepalive = 120
timeout = 120
worker_class = "gthread"
threads = 3

Pooja Mane's answer worked for me, but I had to put the client_max_body_size variable inside of http section.

Unwind is essentially correct that there are many different ways to implement a trie; and for a large, scalable trie, nested dictionaries might become cumbersome -- or at least space inefficient. But since you're just getting started, I think that's the easiest approach; you could code up a simple trie in just a few lines. First, a function to construct the trie:

>>> _end = '_end_'
>>> 
>>> def make_trie(*words):
...     root = dict()
...     for word in words:
...         current_dict = root
...         for letter in word:
...             current_dict = current_dict.setdefault(letter, {})
...         current_dict[_end] = _end
...     return root
... 
>>> make_trie('foo', 'bar', 'baz', 'barz')
{'b': {'a': {'r': {'_end_': '_end_', 'z': {'_end_': '_end_'}}, 
             'z': {'_end_': '_end_'}}}, 
 'f': {'o': {'o': {'_end_': '_end_'}}}}

If you're not familiar with setdefault, it simply looks up a key in the dictionary (here, letter or _end). If the key is present, it returns the associated value; if not, it assigns a default value to that key and returns the value ({} or _end). (It's like a version of get that also updates the dictionary.)

Next, a function to test whether the word is in the trie:

>>> def in_trie(trie, word):
...     current_dict = trie
...     for letter in word:
...         if letter not in current_dict:
...             return False
...         current_dict = current_dict[letter]
...     return _end in current_dict
... 
>>> in_trie(make_trie('foo', 'bar', 'baz', 'barz'), 'baz')
True
>>> in_trie(make_trie('foo', 'bar', 'baz', 'barz'), 'barz')
True
>>> in_trie(make_trie('foo', 'bar', 'baz', 'barz'), 'barzz')
False
>>> in_trie(make_trie('foo', 'bar', 'baz', 'barz'), 'bart')
False
>>> in_trie(make_trie('foo', 'bar', 'baz', 'barz'), 'ba')
False

I'll leave insertion and removal to you as an exercise.

Of course, Unwind's suggestion wouldn't be much harder. There might be a slight speed disadvantage in that finding the correct sub-node would require a linear search. But the search would be limited to the number of possible characters -- 27 if we include _end. Also, there's nothing to be gained by creating a massive list of nodes and accessing them by index as he suggests; you might as well just nest the lists.

Finally, I'll add that creating a directed acyclic word graph (DAWG) would be a bit more complex, because you have to detect situations in which your current word shares a suffix with another word in the structure. In fact, this can get rather complex, depending on how you want to structure the DAWG! You may have to learn some stuff about Levenshtein distance to get it right.

As I understand the new iTunesConnect philosophy :

• you can upload some multiple "eligible" builds to iTunesConnect int the "pre release" tab
• let some other testers test a specific build, via TestFlight (and declared as iTunesConnect users)
• when you come to a stable version, select the correct build version, from the "Versions" tab to submit to the AppStore, the usual way.

To me, you can have like 150 build for a pre release, it doesn't matter.

Personally, I use Emacs with hexl-mod.

Emacs is able to work with really huge files. You can use search/replace value easily. Finally, you can use 'ediff' to do some diffs.

I haven't found any solution using Google's Closure library. So just to complete the list for future vistors, here's how you load a JSON from local file with Closure library:

goog.net.XhrIo.send('../appData.json', function(evt) {
  var xhr = evt.target;
  var obj = xhr.getResponseJson(); //JSON parsed as Javascript object
  console.log(obj);
});

I know that this is too late but here is my approach:

<GridViewColumn x:Name="GridHeaderLocalSize"  Width="100">      
<GridViewColumn.Header>
    <GridViewColumnHeader HorizontalContentAlignment="Right">
        <Grid Width="Auto" HorizontalAlignment="Right">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="100"/>
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Column="0" Text="Local size" TextAlignment="Right" Padding="0,0,5,0"/>
        </Grid>
    </GridViewColumnHeader>
</GridViewColumn.Header>
<GridViewColumn.CellTemplate>
    <DataTemplate>
        <TextBlock Width="{Binding ElementName=GridHeaderLocalSize, Path=Width, FallbackValue=100}"  HorizontalAlignment="Right" TextAlignment="Right" Padding="0,0,5,0" Text="Text" >
        </TextBlock>
    </DataTemplate>
</GridViewColumn.CellTemplate>

The main idea is to bind the width of the cellTemplete element to the width of the ViewGridColumn. Width=100 is default width used until first resize. There isn't any code behind. Everything is in xaml.

No application written in 2017 (or thereafter) that intends to incorporate serious cryptography should use RSA any more. There are better options for PHP public-key cryptography.

There are two big mistakes that people make when they decide to encrypt with RSA:

1. Developers choose the wrong padding mode.
2. Since RSA cannot, by itself, encrypt very long strings, developers will often break a string into small chunks and encrypt each chunk independently. Sort of like ECB mode.

The Best Alternative: sodium_crypto_box_seal() (libsodium)

$keypair = sodium_crypto_box_keypair();
$publicKey = sodium_crypto_box_publickey($keypair);
// ...
$encrypted = sodium_crypto_box_seal(
    $plaintextMessage,
    $publicKey
);
// ...
$decrypted = sodium_crypto_box_seal_open(
    $encrypted,
    $keypair
);

Simple and secure. Libsodium will be available in PHP 7.2, or through PECL for earlier versions of PHP. If you need a pure-PHP polyfill, get paragonie/sodium_compat.

Begrudgingly: Using RSA Properly

The only reason to use RSA in 2017 is, "I'm forbidden to install PECL extensions and therefore cannot use libsodium, and for some reason cannot use paragonie/sodium_compat either."

Your protocol should look something like this:

1. Generate a random AES key.
2. Encrypt your plaintext message with the AES key, using an AEAD encryption mode or, failing that, CBC then HMAC-SHA256.
3. Encrypt your AES key (step 1) with your RSA public key, using RSAES-OAEP + MGF1-SHA256
4. Concatenate your RSA-encrypted AES key (step 3) and AES-encrypted message (step 2).

Instead of implementing this yourself, check out EasyRSA.

I too have struggled with this new pagespeed metric.

Although I have found no practical way to get my score back up to %100 there are a few things I have found helpful.

Combining all css into one file helped a lot. All my sites are back up to %95 - %98.

The only other thing I could think of was to inline all the necessary css (which appears to be most of it - at least for my pages) on the first page to get the sweet high score. Although it may help your speed score this will probably make your page load slower though.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

This has happened to me because the repository was disabled (a repository can be disabled by the owner or Github may disable all private repositories of an account if the account does not pay it's bill).

So you should contact the repository owner and inform him that the repository is disabled.

Using Kotlin:

var timer = object: CountDownTimer(30000, 1000) {
        override fun onTick(millisUntilFinished: Long) {
            tvTimer.setText("seconds remaining: " + millisUntilFinished / 1000)
        }

        override fun onFinish() {
            tvTimer.setText("done!")
        }
    }
timer.start()

I noticed that I was getting this error, because my HTML code did not have <body> tag.

Without a <body>, when document.body.appendChild(form); statement did not have a body object to append.

assylias and Head of Catering have already given your the reason why the error is occurring.

Now regarding what you are doing, from what I understand, you don't need to use Select at all

I guess you are doing this from VBA PowerPoint? If yes, then your code be rewritten as

Dim sourceXL As Object, sourceBook As Object
Dim sourceSheet As Object, sourceSheetSum As Object
Dim lRow As Long
Dim measName As Variant, partName As Variant
Dim filepath As String

filepath = CStr(FileDialog)

'~~> Establish an EXCEL application object
On Error Resume Next
Set sourceXL = GetObject(, "Excel.Application")

'~~> If not found then create new instance
If Err.Number <> 0 Then
    Set sourceXL = CreateObject("Excel.Application")
End If
Err.Clear
On Error GoTo 0

Set sourceBook = sourceXL.Workbooks.Open(filepath)
Set sourceSheet = sourceBook.Sheets("Measurements")
Set sourceSheetSum = sourceBook.Sheets("Analysis Summary")

lRow = sourceSheetSum.Range("C" & sourceSheetSum.Rows.Count).End(xlUp).Row
measName = sourceSheetSum.Range("C3:C" & lRow)

lRow = sourceSheetSum.Range("D" & sourceSheetSum.Rows.Count).End(xlUp).Row
partName = sourceSheetSum.Range("D3:D" & lRow)

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes,
• MINOR version when you add functionality in a backwards-compatible manner, and
• PATCH version when you make backwards-compatible bug fixes.

Version Code & Version Name

As you may know, on android you have to define two version fields for an app: the version code (android:versionCode) and the version name (android:versionName). The version code is an incremental integer value that represents the version of the application code. The version name is a string value that represents the “friendly” version name displayed to the users.

I would suggest:

def foo(element):
    do something
    if not check: return
    do more (because check was succesful)
    do much much more...

From the structure of your source Object, I would try:

containerObject= new JSONObject(container);
 if(containerObject.has("LabelData")){
  JSONObject innerObject = containerObject.getJSONObject("LabelData");
     if(innerObject.has("video")){
        //Do with video
    }
}

Without make validation patterns, You can easily trim begin and end spaces using these modules.Try this.

Thank you.

You can use ViewChild

<child-tag #varName></child-tag>

@ViewChild('varName') someElement;

ngAfterViewInit() {
  someElement...
}

where varName is a template variable added to the element. Alternatively, you can query by component or directive type.

There are alternatives like ViewChildren, ContentChild, ContentChildren.

@ViewChildren can also be used in the constructor.

constructor(@ViewChildren('var1,var2,var3') childQuery:QueryList)

The advantage is that the result is available earlier.

See also http://www.bennadel.com/blog/3041-constructor-vs-property-querylist-injection-in-angular-2-beta-8.htm for some advantages/disadvantages of using the constructor or a field.

Note: @Query() is the deprecated predecessor of @ContentChildren()

As in Flutter everything is a widget, I decided to wrap the SystemChannels.textInput.invokeMethod('TextInput.hide'); and the FocusScope.of(context).requestFocus(FocusNode()); approach in a short utility module with a widget and a mixin in it.

With the widget, you can wrap any widget (very convenient when using a good IDE support) with the KeyboardHider widget:

class SimpleWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return KeyboardHider(
      /* Here comes a widget tree that eventually opens the keyboard,
       * but the widget that opened the keyboard doesn't necessarily
       * takes care of hiding it, so we wrap everything in a
       * KeyboardHider widget */
      child: Container(),
    );
  }
}

With the mixin, you can trigger hiding the keyboard from any state or widget upon any interaction:

class SimpleWidget extends StatefulWidget {
  @override
  _SimpleWidgetState createState() => _SimpleWidgetState();
}

class _SimpleWidgetState extends State<SimpleWidget> with KeyboardHiderMixin {
  @override
  Widget build(BuildContext context) {
    return RaisedButton(
      onPressed: () {
        // Hide the keyboard:
        hideKeyboard();
        // Do other stuff, for example:
        // Update the state, make an HTTP request, ...
      },
    );
  }
}

Just create a keyboard_hider.dart file and the widget and mixin are ready to use:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

/// Mixin that enables hiding the keyboard easily upon any interaction or logic
/// from any class.
abstract class KeyboardHiderMixin {
  void hideKeyboard({
    BuildContext context,
    bool hideTextInput = true,
    bool requestFocusNode = true,
  }) {
    if (hideTextInput) {
      SystemChannels.textInput.invokeMethod('TextInput.hide');
    }
    if (context != null && requestFocusNode) {
      FocusScope.of(context).requestFocus(FocusNode());
    }
  }
}

/// A widget that can be used to hide the text input that are opened by text
/// fields automatically on tap.
///
/// Delegates to [KeyboardHiderMixin] for hiding the keyboard on tap.
class KeyboardHider extends StatelessWidget with KeyboardHiderMixin {
  final Widget child;

  /// Decide whether to use
  /// `SystemChannels.textInput.invokeMethod('TextInput.hide');`
  /// to hide the keyboard
  final bool hideTextInput;
  final bool requestFocusNode;

  /// One of hideTextInput or requestFocusNode must be true, otherwise using the
  /// widget is pointless as it will not even try to hide the keyboard.
  const KeyboardHider({
    Key key,
    @required this.child,
    this.hideTextInput = true,
    this.requestFocusNode = true,
  })  : assert(child != null),
        assert(hideTextInput || requestFocusNode),
        super(key: key);

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      behavior: HitTestBehavior.opaque,
      onTap: () {
        hideKeyboard(
          context: context,
          hideTextInput: hideTextInput,
          requestFocusNode: requestFocusNode,
        );
      },
      child: child,
    );
  }
}

by typing yes it wont charge taxes, by typing no it will charge taxes.

Tip #2

Can't you use the classical 2> redirection operator.

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) 2> $NULL
if(!$?){
   'foo'
}

I don't like errors so I avoid them at all costs.

For me this worked:

INSERT INTO [MyTable]
           ([ValidFrom]
           ,[ValidTo])
       VALUES
           ('2020-01-27 14:54:11.000'
           ,'2023-01-27 14:52:50.000')

Here is a working version using v3 of docker-compose.yml. The key is the volumes directive:

mysql:
  image: mysql:5.6
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: root
    MYSQL_USER: theusername
    MYSQL_PASSWORD: thepw
    MYSQL_DATABASE: mydb
  volumes:
    - ./data:/docker-entrypoint-initdb.d

In the directory that I have my docker-compose.yml I have a data dir that contains .sql dump files. This is nice because you can have a .sql dump file per table.

I simply run docker-compose up and I'm good to go. Data automatically persists between stops. If you want remove the data and "suck in" new .sql files run docker-compose down then docker-compose up.

If anyone knows how to get the mysql docker to re-process files in /docker-entrypoint-initdb.d without removing the volume, please leave a comment and I will update this answer.

If each file only has one sequence of aminoacids, I wouldn't use regular expressions at all. Just something like this:

def read_amino_acid_sequence(path):
    with open(path) as sequence_file:
        title = sequence_file.readline() # read 1st line
        aminoacid_sequence = sequence_file.read() # read the rest

    # some cleanup, if necessary
    title = title.strip() # remove trailing white spaces and newline
    aminoacid_sequence = aminoacid_sequence.replace(" ","").replace("\n","")
    return title, aminoacid_sequence

I was trying something like this using the $(...).val() function, but the function did not exist. It turns out that you can manually set the value the same way you do it for an <input>:

// Set value to Indonesia ("ID"):
$('#country').value = 'ID'

...and it get's automatically updated in the select. Works on Firefox at least; you might want to try it out in the others.

You need to give the array a size:

public static void main(String args[])
{
    int array[] = new int[4];
    int number = 5, i = 0,j = 0;
    while (i<4){
        array[i]=number;
        i=i+1;
    }
    while (j<4){
        System.out.println(array[j]);
        j++;
    }
}

I'm on Windows 7 x64 and Visual Studio 2017. I get this error trying to compile a cython script. That's how I solved: I copied and pasted rc.exe and rcdll.dll from:

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

to

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\x86_amd64

My solution is:

#include <iostream>


    int fib(int number);

    void call_fib(void);

    int main()
    {
    call_fib();
    return 0;
    }

    void call_fib(void)
    {
      int input;
      std::cout<<"enter a number\t";
      std::cin>> input;
      if (input <0)
      {
        input=0;
        std::cout<<"that is not a valid input\n"   ;
        call_fib();
     }
     else 
     {
         std::cout<<"the "<<input <<"th fibonacci number is "<<fib(input);
     }

    }





    int fib(int x)
    {
     if (x==0){return 0;}
     else if (x==2 || x==1)
    {
         return 1;   
    }

    else if (x>0)
   {
        return fib(x-1)+fib(x-2);
    }
    else 
     return -1;
    }

it returns fib(0)=0 and error if negitive

I've created an extension method for this which makes use of SemaphoreSlim and also allows to set maximum degree of parallelism

    /// Concurrently Executes async actions for each item of <see cref="IEnumerable<typeparamref name="T"/>
    /// </summary>
    /// <typeparam name="T">Type of IEnumerable</typeparam>
    /// <param name="enumerable">instance of <see cref="IEnumerable<typeparamref name="T"/>"/></param>
    /// <param name="action">an async <see cref="Action" /> to execute</param>
    /// <param name="maxDegreeOfParallelism">Optional, An integer that represents the maximum degree of parallelism,
    /// Must be grater than 0</param>
    /// <returns>A Task representing an async operation</returns>
    /// <exception cref="ArgumentOutOfRangeException">If the maxActionsToRunInParallel is less than 1</exception>
    public static async Task ForEachAsyncConcurrent<T>(
        this IEnumerable<T> enumerable,
        Func<T, Task> action,
        int? maxDegreeOfParallelism = null)
    {
        if (maxDegreeOfParallelism.HasValue)
        {
            using (var semaphoreSlim = new SemaphoreSlim(
                maxDegreeOfParallelism.Value, maxDegreeOfParallelism.Value))
            {
                var tasksWithThrottler = new List<Task>();

                foreach (var item in enumerable)
                {
                    // Increment the number of currently running tasks and wait if they are more than limit.
                    await semaphoreSlim.WaitAsync();

                    tasksWithThrottler.Add(Task.Run(async () =>
                    {
                        await action(item).ContinueWith(res =>
                        {
                            // action is completed, so decrement the number of currently running tasks
                            semaphoreSlim.Release();
                        });
                    }));
                }

                // Wait for all tasks to complete.
                await Task.WhenAll(tasksWithThrottler.ToArray());
            }
        }
        else
        {
            await Task.WhenAll(enumerable.Select(item => action(item)));
        }
    }

Sample Usage:

await enumerable.ForEachAsyncConcurrent(
    async item =>
    {
        await SomeAsyncMethod(item);
    },
    5);

This helped me at the end:

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

In Swift 3.0

images.sort(by: { (first: imageFile, second: imageFile) -> Bool in
    first. fileID < second. fileID
})

Here are my steps for the task:

1. Create PNG image file of size 512x512 pixels
2. In Android Studio, in project view, highlight a mipmap directory
3. In menu, go to File>New>Image Asset
4. Click Image Button in Asset type button row
5. Click on 3 Dot Box at right of Path Box.
6. Drag image to source asset box
7. Click Next (Note: Existing launcher files will be overwritten)
8. Click Finish

I understand the original post is for Oracle 10 but this is for reference by anyone else who finds it via Google.

Under Oracle 12c, I found that that my registry$history is empty. This works instead:

select * from registry$sqlpatch;

Use this code. It worked for me. I considered for 3 columns. Change the loop value for your code.

TableColumn column = null;
for (int i = 0; i < 3; i++) {
    column = table.getColumnModel().getColumn(i);
    if (i == 0) 
        column.setMaxWidth(10);
    if (i == 2)
        column.setMaxWidth(50);
}

A pure virtual function is usually not (but can be) implemented in a base class and must be implemented in a leaf subclass.

You denote that fact by appending the "= 0" to the declaration, like this:

class AbstractBase
{
    virtual void PureVirtualFunction() = 0;
}

Then you cannot declare and instantiate a subclass without it implementing the pure virtual function:

class Derived : public AbstractBase
{
    virtual void PureVirtualFunction() override { }
}

By adding the override keyword, the compiler will ensure that there is a base class virtual function with the same signature.

No, and they're being phased out by PHP 6 so if you appreciate code longevity, simply don't use them or the <% ... %> tags.

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.

It's actually best practice to provide the os with a path link.

With windows 10

1. open up file explorer
2. right click on "this pc" and select "properties"
3. Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
4. At the bottom of the next window, click on the "Environment Variables" button.
5. On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
6. Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
7. Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.

<div id="video_box">
  <div id="video_overlays"></div>
  <div>
    <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" type="video/webm" onclick="this.play();">Your browser does not support this streaming content.</video>
  </div>
</div>

for this you need to just add css like this:

#video_overlays {
  position: absolute;
  background-color: rgba(0, 0, 0, 0.46);
  z-index: 2;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}
#video_box{position: relative;}

If you want a separate .js file to better organize your routes, just create a variable in the app.js file pointing to its location in the filesystem:

var wf = require(./routes/wf);

then,

app.get('/wf', wf.foo );

where .foo is some function declared in your wf.js file. e.g

// wf.js file 
exports.foo = function(req,res){

          console.log(` request object is ${req}, response object is ${res} `);

}

Most of the time, the problem is due to some error on the human side. In my case, I was using some classes whose names are similar. I have added the empty() method under one class; however, my code was calling the empty() method from another class. At that moment, the mind was stuck. I was running make clean, and remake thinking that it was some older version of the header got used. After walking away for a moment, I found that problem right away. We programmers tends to blame others first. Maybe we should insist on ourselves to be wrong first.

Sometimes, I forget to write the latest update to disk and looking at the correct version of the code, but the compiler is seeing the wrong version of the code. This situation may be less a issue on IDE (I use vi to do coding).

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

I don't know if Boost has more specific functions, but you can do it with the standard library.

Given std::vector<double> v, this is the naive way:

#include <numeric>

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

double sq_sum = std::inner_product(v.begin(), v.end(), v.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size() - mean * mean);

This is susceptible to overflow or underflow for huge or tiny values. A slightly better way to calculate the standard deviation is:

double sum = std::accumulate(v.begin(), v.end(), 0.0);
double mean = sum / v.size();

std::vector<double> diff(v.size());
std::transform(v.begin(), v.end(), diff.begin(),
               std::bind2nd(std::minus<double>(), mean));
double sq_sum = std::inner_product(diff.begin(), diff.end(), diff.begin(), 0.0);
double stdev = std::sqrt(sq_sum / v.size());

UPDATE for C++11:

The call to std::transform can be written using a lambda function instead of std::minus and std::bind2nd(now deprecated):

std::transform(v.begin(), v.end(), diff.begin(), [mean](double x) { return x - mean; });

For a JavaScript object stored in a Django field as text, which needs to again become a JavaScript object dynamically inserted into on-page script, you need to use both escapejs and JSON.parse():

var CropOpts = JSON.parse("{{ profile.last_crop_coords|escapejs }}");

Django's escapejs handles the quoting properly, and JSON.parse() converts the string back into a JS object.

You need to call CLASS in button

<button class="tim" id="rock" onClick="choose(1)">Rock</button>



<style>
.tim{
font-size: 18px;
border: 2px solid #AD235E;
border-radius: 100px;
width: 150px;
height: 150px; background-image: url(images/Sun.jpg);
}
</style>

Give your textbox a name and then use TextBoxName.Text = String.Empty;

It's best if you judge on your own,

1) Sublime works on Mac & Linux that may be its plus point, with VI mode that makes things easily searchable for the VI lover(UNIX & Linux).

http://text-editors.findthebest.com/compare/9-45/Notepad-vs-Sublime-Text

This Link is no more working so please watch this video for similar details Video

Initial observation revealed that everything else should work fine and almost similar;(with help of available plugins in notepad++)

Some Variation: Some user find plugins useful for PHP coders on that

http://codelikeapoem.com/2013/01/goodbye-notepad-hellooooo-sublime-text.html

although, there are many plugins for Notepad Plus Plus ..

I am not sure of your requirements, nor I am promoter of either of these editors :)

So, judge on basis of your requirements, this should satisfy you query...

Yes we can add that both are evolving and changing fast..

This works for 4.0.

<nav class="navbar navbar-expand-sm fixed-top navbar-light">
or
<nav class="navbar navbar-expand-lg fixed-top navbar-dark">

key item is fixed-top, otherwise, white or default page background is displayed even if there is a image top. navbar-light gives dark letters, navbar-dark shows light text.

You could either do:

x = raw_input("enter your name")
print "your name is %s " % x

or:

x = str(input("enter your name"))
print "your name is %s" % x

I've just made a small jQuery plugin for that.

It follows your syntax:

var myDiv = $.create("div");

DOM node ID can be specified as second parameter:

var secondItem = $.create("div","item2");

Is it serious? No. But this syntax is better than $("<div></div>"), and it's a very good value for that money.

(Answer partially copied from: jQuery document.createElement equivalent?)

Shadowbox is your best choice. Check it out.

On the side note, here is how the various plyr functions correspond to the base *apply functions (from the intro to plyr document from the plyr webpage http://had.co.nz/plyr/)

Base function   Input   Output   plyr function 
---------------------------------------
aggregate        d       d       ddply + colwise 
apply            a       a/l     aaply / alply 
by               d       l       dlply 
lapply           l       l       llply  
mapply           a       a/l     maply / mlply 
replicate        r       a/l     raply / rlply 
sapply           l       a       laply 

One of the goals of plyr is to provide consistent naming conventions for each of the functions, encoding the input and output data types in the function name. It also provides consistency in output, in that output from dlply() is easily passable to ldply() to produce useful output, etc.

Conceptually, learning plyr is no more difficult than understanding the base *apply functions.

plyr and reshape functions have replaced almost all of these functions in my every day use. But, also from the Intro to Plyr document:

Related functions tapply and sweep have no corresponding function in plyr, and remain useful. merge is useful for combining summaries with the original data.

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

The Void class is an uninstantiable placeholder class to hold a reference to the Class object representing the Java keyword void.

So any of the following would suffice:

• parameterizing with Object and returning new Object() or null
• parameterizing with Void and returning null
• parameterizing with a NullObject of yours

You can't make this method void, and anything else returns something. Since that something is ignored, you can return anything.

Old style using Resultset

@Transactional(readOnly=true)
public void accessUser() {
    EntityManager em = this.getEntityManager();
    org.hibernate.Session session = em.unwrap(org.hibernate.Session.class);
    session.doWork(new Work() {
        @Override
        public void execute(Connection con) throws SQLException {
            try (PreparedStatement stmt = con.prepareStatement(
                    "SELECT u.username, u.name, u.email, 'blabla' as passe, login_type as loginType FROM users u")) {
                ResultSet rs = stmt.executeQuery();
                ResultSetMetaData rsmd = rs.getMetaData();
                for (int i = 1; i <= rsmd.getColumnCount(); i++) {
                    System.out.print(rsmd.getColumnName(i) + " (" + rsmd.getColumnTypeName(i) + ") / ");
                }
                System.out.println("");
                while (rs.next()) {
                    System.out.println("Found username " + rs.getString("USERNAME") + " name " + rs.getString("NAME") + " email " + rs.getString("EMAIL") + " passe " + rs.getString("PASSE") + " email " + rs.getInt("LOGIN_TYPE"));
                }
            }
        }
    });
}

You can add .vim files to be executed whenever vim switches to a particular filetype.

For example, I have a file ~/.vim/after/ftplugin/html.vim with this contents:

setlocal shiftwidth=2
setlocal tabstop=2

Which causes vim to use tabs with a width of 2 characters for indenting (the noexpandtab option is set globally elsewhere in my configuration).

This is described here: http://vimdoc.sourceforge.net/htmldoc/usr_05.html#05.4, scroll down to the section on filetype plugins.

I use div instead of tables and am able to target classes within the main class, as below:

CSS

.main {
    .width: 800px;
    .margin: 0 auto;
    .text-align: center;
}
.main .table {
    width: 80%;
}
.main .row {
   / ***something ***/
}
.main .column {
    font-size: 14px;
    display: inline-block;
}
.main .left {
    width: 140px;
    margin-right: 5px;
    font-size: 12px;
}
.main .right {
    width: auto;
    margin-right: 20px;
    color: #fff;
    font-size: 13px;
    font-weight: normal;
}

HTML

<div class="main">
    <div class="table">
        <div class="row">
            <div class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

If you want to style a particular "cell" exclusively you can use another sub-class or the id of the div e.g:

.main #red { color: red; }

<div class="main">
    <div class="table">
        <div class="row">
            <div id="red" class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

I discovered a neat workaround for mingw32 (i.e. for those of you using the version of bash which is installed by git-scm.com on windows):

code () { VSCODE_CWD="$PWD" cmd //c code $* ;}

This is a complete program you can compile and run it.

import java.util.Scanner;

class Strlen{

    public static void main(String...args){
        Scanner sc = new Scanner(System.in);
        System.out.print("\nEnter Your Name =>" +"  ");
        String ab = sc.nextLine();
        System.out.println("\nName Length is:" +len(ab));
    }

    public static int len(String ab){
        char[] ac = ab.toCharArray();
        int i = 0, k = 0;

        try{
            for(i=0,k=0;ac[i]!='\0';i++)
                k++;
        }
        catch(Exception e){
        }
        return k;
    }

}

d <- 5
for(i in 1:10) { 
 nam <- paste("A", i, sep = "")
 assign(nam, rnorm(3)+d)
}

The closest equivalent to your VB would be (see this):

Convert.IsDBNull()

But there are a number of ways to do this, and most are linked from here

You can do the following while read loop, that will be fed by the result of the grep command using the so called process substitution:

while IFS= read -r result
do
    #whatever with value $result
done < <(grep "xyz" abc.txt)

This way, you don't have to store the result in a variable, but directly "inject" its output to the loop.

Note the usage of IFS= and read -r according to the recommendations in BashFAQ/001: How can I read a file (data stream, variable) line-by-line (and/or field-by-field)?:

The -r option to read prevents backslash interpretation (usually used as a backslash newline pair, to continue over multiple lines or to escape the delimiters). Without this option, any unescaped backslashes in the input will be discarded. You should almost always use the -r option with read.

In the scenario above IFS= prevents trimming of leading and trailing whitespace. Remove it if you want this effect.

Regarding the process substitution, it is explained in the bash hackers page:

Process substitution is a form of redirection where the input or output of a process (some sequence of commands) appear as a temporary file.

Could always do:

db.foo.find().forEach(function(f){print(tojson(f, '', true));});

To get that compact view.

Also, I find it very useful to limit the fields returned by the find so:

db.foo.find({},{name:1}).forEach(function(f){print(tojson(f, '', true));});

which would return only the _id and name field from foo.

Did some tests both on linux and windows. I use a test file containing lines ending in LF and also lines ending in CRLF.
File is committed , removed and then checked out. The value of core.autocrlf is set before commit and also before checkout. The result is below.

commit core.autocrlf false, remove, checkout core.autocrlf false: LF=>LF   CRLF=>CRLF  
commit core.autocrlf false, remove, checkout core.autocrlf input: LF=>LF   CRLF=>CRLF  
commit core.autocrlf false, remove, checkout core.autocrlf true : LF=>LF   CRLF=>CRLF  
commit core.autocrlf input, remove, checkout core.autocrlf false: LF=>LF   CRLF=>LF  
commit core.autocrlf input, remove, checkout core.autocrlf input: LF=>LF   CRLF=>LF  
commit core.autocrlf input, remove, checkout core.autocrlf true : LF=>CRLF CRLF=>CRLF  
commit core.autocrlf true, remove, checkout core.autocrlf false: LF=>LF   CRLF=>LF  
commit core.autocrlf true, remove, checkout core.autocrlf input: LF=>LF   CRLF=>LF  
commit core.autocrlf true,  remove, checkout core.autocrlf true : LF=>CRLF CRLF=>CRLF  

Just want to throw something in to help people still having this problem. (for me at least) the css is showing that it puts default classes of level1, level2, and level3 on each piece of the menu(level 1 being the menu, level2 being the first dropdown, level3 being the third popout). Setting the padding in css

.level2
{
padding: 2px 2px 2px 2px;
}

does work for adding the padding to each li in the first dropdown.

Update your node.js installation.The following commands should do it (from here):

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Edit: okay, if you really have a good reason to run an ancient version of the software, npm set ca null will fix the issue. It happened, because built-in npm certificate has expired over the years.

Keep the labels from your original file like this:

df = read.table('data.txt', header = T)

If you have columns named x and y, you can address them like this:

df$x
df$y

If you'd like to actually delete the first row from a data.frame, you can use negative indices like this:

df = df[-1,]

If you'd like to delete a column from a data.frame, you can assign NULL to it:

df$x = NULL

Here are some simple examples of how to create and manipulate a data.frame in R:

# create a data.frame with 10 rows
> x = rnorm(10)
> y = runif(10)
> df = data.frame( x, y )

# write it to a file
> write.table( df, 'test.txt', row.names = F, quote = F )

# read a data.frame from a file: 
> read.table( df, 'test.txt', header = T )

For the sake of completeness, here's a simple one-liner I ended up with (I had no need checking for non-Foo-properties):

var Foo = function(){ this.bar = 1; };

// angular version
var foo = angular.extend(new Foo(), angular.fromJson('{ "bar" : 2 }'));

// jquery version
var foo = jQuery.extend(new Foo(), jQuery.parseJSON('{ "bar" : 3 }'));

Add this annotation to your method

@RequestMapping(value = "/getString", method = RequestMethod.GET, produces = "application/json")

If you are using Visual Studio, then you can use "Start Without Debugging" in the Debug menu.

It will automatically write "Press any key to continue . . ." to the console for you upon completion of the application and it will leave the console open for you until a key is pressed.

A more robust way, supposing there are multiple PDF's or just one !

import os
from PyPDF2 import PdfFileWriter, PdfFileReader
from io import BytesIO

mydir = # specify path to your directory where PDF or PDF's are

for arch in os.listdir(mydir): 
    buffer = io.BytesIO()
    archpath = os.path.join(mydir, arch)
    with open(archpath) as f:
            pdfFileObj = open(archpath, 'rb')
            pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
            pdfReader.numPages
            pageObj = pdfReader.getPage(0) 
            ley = pageObj.extractText()
            file1 = open("myfile.txt","w")
            file1.writelines(ley)
            file1.close()
            

Navigate to http://get.udid.io/ from Safari on your iOS device. It works like a charm and requires neither iTunes nor any other computer. No app installed either.

EDIT:

Also, have a look at Getting a device UDID from .mobileconfig if you (understandably) would rather have this .mobileconfig certificate hosted on a server of yours.

MAKE YOUR OWN:

Have a copy of the .mobileconfig example hosted on your server and write 2-3 small scripts in your favorite language to handle the following flow:

1. Navigate on Safari to a URL redirecting to enroll.mobileconfig below. This makes iOS open the Settings app and show the profile.
2. Upon accepting the profile, iOS switches back to Safari and posts the DeviceAttributes array to the URL specified enroll.mobileconfig.
3. The POST data will contain a .plist file with the requested attributes (see example below). One of which will be the holy UDID.

Remark: You should probably have some user friendly messages. Specifically, we even have a step 0. where the user is asked to provide their name and e-mail that we store temporarily in the HTTP session and then redirect the request to the mobileconfig profile. We ultimately match this info with the iPhone data and send a friendly confirmation e-mail. HTH.

You will need to define the repository outside of buildscript. The buildscript configuration block only sets up the repositories and dependencies for the classpath of your build script but not your application.

To remove the horizontal scroll bar, use the following code. It 100% works.

html, body {
    overflow-x: hidden;
}

Columns of data frames are already vectors, you just have to pull them out. Note that you place the column you want after the comma, not before it:

> newV <- df[,1]
> newV
[1] 1 2 4 2

If you actually want a row, then do what Ben said and please use words correctly in the future.

I know, I am tooooo late to post an answer, but hoping that it might help someone. Plus, I just solved this issue I had with my tests. This is what I had in my test:

My test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "path-to-context" })
@Transactional
public class MyIntegrationTest 

Context xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
   <property name="driverClassName" value="${jdbc.driverClassName}" />
   <property name="url" value="${jdbc.url}" />
   <property name="username" value="${jdbc.username}" />
   <property name="password" value="${jdbc.password}" />
</bean>

I still had the problem that, the database was not being cleaned up automatically.

Issue was resolved when I added following property to BasicDataSource

<property name="defaultAutoCommit" value="false" />

Hope it helps.

You can additionally use libraries that perform type validation of your json, such as Sparkson. They allow you to define a TypeScript class, to which you'd like to parse your response, in your case it could be:

import { Field } from "sparkson";
class Response {
   constructor(
      @Field("name") public name: string,
      @Field("error") public error: boolean
   ) {}
}

The library will validate if the required fields are present in the JSON payload and if their types are correct. It can also do a bunch of validations and conversions.

Your method is right, all you have to do is add a .0 after both the tens and it will fix your problem!

double example = Math.round((187/35) * 10.0) / 10.0;

The output would be:

5.3

If you are binding a List

List<Student> student = new List<Student>();

dataGridView1.DataSource = student.ToList();
student .Add(new Student());

//Reset the Datasource
dataGridView1.DataSource = null;
dataGridView1.DataSource = student;

If you are binding DataTable

DataTable table = new DataTable();

 DataRow newRow = table.NewRow();

// Add the row to the rows collection.
table.Rows.Add(newRow);

When you run the command git checkout commit_id then HEAD detached from 13ca5593d(say commit-id) and branch will be on longer available.

Move back to previous location run the command step wise -

1. git pull origin branch_name (say master)
2. git checkout branch_name
3. git pull origin branch_name

You will be back to the previous location with an updated commit from the remote repository.

Double check that the DocumentRoot path is correct. That can cause this error.

The second button from the left. The one on the right of the house in the image you posted is your logout button.

For your error message try this link in the documentation: http://wiki.phpmyadmin.net/pma/Configuration_storage

Make certain you have a phpadmin control user account created. This is covered in the second paragraph in on the documentation page in the link.

TL;DR

git show <commit>

Show

To show what a commit did with stats:

git show <commit> --stat

Log

To show commit log with differences introduced for each commit in a range:

git log -p <commit1> <commit2>

What is <commit>?

Each commit has a unique id we reference here as <commit>. The unique id is an SHA-1 hash – a checksum of the content you’re storing plus a header. #TMI

If you don't know your <commit>:

1. git log to view the commit history

2. Find the commit you care about.

$(".hit").click(function(){
   var values = [];
   var table = $(this).closest("table");
   table.find("tr").each(function() {
      values.push($(this).find("td:first").html());
   });

   alert(values);    
});

You should avoid $(".hit") it's really inefficient. Try using event delegation instead.

Easiest way is to open CMD or powershell as administrator and type

set PATH=%PATH%;C:\Python27

It is nice for a Python module to have a docstring, explaining what the module does, what it provides, examples of how to use the classes. This is different from the comments that you often see at the beginning of a file giving the copyright and license information, which IMO should not go in the docstring (some even argue that they should disappear altogether, see e.g. Get Rid of Source Code Templates)

With Pylint 2.4 and above, you can differentiate between the various missing-docstring by using the three following sub-messages:

• C0114 (missing-module-docstring)
• C0115 (missing-class-docstring)
• C0116 (missing-function-docstring)

So the following .pylintrc file should work:

[MASTER]
disable=
    C0114, # missing-module-docstring

For previous versions of Pylint, it does not have a separate code for the various place where docstrings can occur, so all you can do is disable C0111. The problem is that if you disable this at module scope, then it will be disabled everywhere in the module (i.e., you won't get any C line for missing function / class / method docstring. Which arguably is not nice.

So I suggest adding that small missing docstring, saying something like:

"""
high level support for doing this and that.
"""

Soon enough, you'll be finding useful things to put in there, such as providing examples of how to use the various classes / functions of the module which do not necessarily belong to the individual docstrings of the classes / functions (such as how these interact, or something like a quick start guide).

On windows:

Add an environmental variable (in both system and user's variables, I have some weird problem, that it gets the var from various places, so I add them in both of them).

Name it MAVEN_OPTS.

Value will be: -Xms1024m -Xmx3000m -XX:MaxPermSize=1024m -XX:+CMSClassUnloadingEnabled

The numbers can be different, make them relative to your mem size.

I had that problem and this fixed it, nothing else!

Continuing with Mecki's suggestion, this article pthread mutex vs pthread spinlock on Alexander Sandler's blog, Alex on Linux shows how the spinlock & mutexes can be implemented to test the behavior using #ifdef.

However, be sure to take the final call based on your observation, understanding as the example given is an isolated case, your project requirement, environment may be entirely different.

My approach has always been to use StringBuilder when concatenating 4 or more strings OR When I don't know how may concatenations are to take place.

Note: The snippet would only work if the iframe is with the same origin.

Other answers proposed the load event, but it fires after the new page in the iframe is loaded. You might need to be notified immediately after the URL changes, not after the new page is loaded.

Here's a plain JavaScript solution:

function iframeURLChange(iframe, callback) {_x000D_
    var unloadHandler = function () {_x000D_
        // Timeout needed because the URL changes immediately after_x000D_
        // the `unload` event is dispatched._x000D_
        setTimeout(function () {_x000D_
            callback(iframe.contentWindow.location.href);_x000D_
        }, 0);_x000D_
    };_x000D_
_x000D_
    function attachUnload() {_x000D_
        // Remove the unloadHandler in case it was already attached._x000D_
        // Otherwise, the change will be dispatched twice._x000D_
        iframe.contentWindow.removeEventListener("unload", unloadHandler);_x000D_
        iframe.contentWindow.addEventListener("unload", unloadHandler);_x000D_
    }_x000D_
_x000D_
    iframe.addEventListener("load", attachUnload);_x000D_
    attachUnload();_x000D_
}_x000D_
_x000D_
iframeURLChange(document.getElementById("mainframe"), function (newURL) {_x000D_
    console.log("URL changed:", newURL);_x000D_
});

<iframe id="mainframe" src=""></iframe>

This will successfully track the src attribute changes, as well as any URL changes made from within the iframe itself.

Tested in all modern browsers.

I made a gist with this code as well. You can check my other answer too. It goes a bit in-depth into how this works.

adapter.setNotifyDataChanged()

should do the trick.

If you simply want to create a new branch without immediately changing to it, you could do the following:

git branch newbranch v1.0

dir(sys) says no. len(sys.argv) works, but in Python it is better to ask for forgiveness than permission, so

#!/usr/bin/python
import sys
try:
    in_file = open(sys.argv[1], "r")
except:
    sys.exit("ERROR. Can't read supplied filename.")
text = in_file.read()
print(text)
in_file.close()

works fine and is shorter.

If you're going to exit anyway, this would be better:

#!/usr/bin/python
import sys
text = open(sys.argv[1], "r").read()
print(text)

I'm using print() so it works in 2.7 as well as Python 3.

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

I tried the suggested solutions by everyone, but I had to improvise code myself to actually make it work. Following is my improvised code:

import signal
import sys
import time

def signal_handler(signal, frame):
    print('You pressed Ctrl+C!')
    print(signal) # Value is 2 for CTRL + C
    print(frame) # Where your execution of program is at moment - the Line Number
    sys.exit(0)

#Assign Handler Function
signal.signal(signal.SIGINT, signal_handler)

# Simple Time Loop of 5 Seconds
secondsCount = 5
print('Press Ctrl+C in next '+str(secondsCount))
timeLoopRun = True 
while timeLoopRun:  
    time.sleep(1)
    if secondsCount < 1:
        timeLoopRun = False
    print('Closing in '+ str(secondsCount)+ ' seconds')
    secondsCount = secondsCount - 1

Using only native JS, something like this will work:

a = [{ value:"4a55eff3-1e0d-4a81-9105-3ddd7521d642", display:"Jamsheer"}, { value:"644838b3-604d-4899-8b78-09e4799f586f", display:"Muhammed"}, { value:"b6ee537a-375c-45bd-b9d4-4dd84a75041d", display:"Ravi"}, { value:"e97339e1-939d-47ab-974c-1b68c9cfb536", display:"Ajmal"},  { value:"a63a6f77-c637-454e-abf2-dfb9b543af6c", display:"Ryan"}]_x000D_
b = [{ value:"4a55eff3-1e0d-4a81-9105-3ddd7521d642", display:"Jamsheer", $$hashKey:"008"}, { value:"644838b3-604d-4899-8b78-09e4799f586f", display:"Muhammed", $$hashKey:"009"}, { value:"b6ee537a-375c-45bd-b9d4-4dd84a75041d", display:"Ravi", $$hashKey:"00A"}, { value:"e97339e1-939d-47ab-974c-1b68c9cfb536", display:"Ajmal", $$hashKey:"00B"}]_x000D_
_x000D_
function comparer(otherArray){_x000D_
  return function(current){_x000D_
    return otherArray.filter(function(other){_x000D_
      return other.value == current.value && other.display == current.display_x000D_
    }).length == 0;_x000D_
  }_x000D_
}_x000D_
_x000D_
var onlyInA = a.filter(comparer(b));_x000D_
var onlyInB = b.filter(comparer(a));_x000D_
_x000D_
result = onlyInA.concat(onlyInB);_x000D_
_x000D_
console.log(result);

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

original answer moved to this topic .

Putting my two cents here. I wanted to do the same without hardcoding the URL for my specific request. So i came up with this solution.

To append 'api' to my baseURL, I have my default baseURL set as,

axios.defaults.baseURL = '/api/';

Then in my specific request, after explicitly setting the method and url, i set the baseURL to '/'

axios({
    method:'post',
    url:'logout',
    baseURL: '/',
   })
   .then(response => {
      window.location.reload();
   })
   .catch(error => {
       console.log(error);
   });

Hans Passant was correct, I added a handler for AppDomain.CurrentDomain.UnhandledException as described here http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception(v=vs.71).aspx I was able to find the exception that was occurring and corrected it.

My 2 cents here (even when there are a lot of cool/working responses)

I created this alias in my .gitconfig

[alias]
 ...
 conflicts = !git diff --name-only --diff-filter=U | grep -oE '[^/ ]+$'

which is going to show me just the names of the files with conflicts... not their whole path :)

Since Fedora 22 yum has been deprecated so the commands given in other answers will actually fire up 'Dandified yum' i.e. dnf. So the new command to install g++ in recent distributions is

su -c "dnf install gcc-c++"

As of Nov 2015 this installs the 5.1.1 version.
Also note that in Fedora 23 when I gave the command g++ -v, Fedora automatically asked me if I want to install gcc-c++ package. I think thats nice.(After the install it also ran the command g++ -v for me)
Only nit pick that I can do about it is that instead of a progress indicator you just get * Downloading packages... message which you may not like if you are on a slow internet connection.

Setup 1: compile your own glibc without dedicated GCC and use it

Since it seems impossible to do just with symbol versioning hacks, let's go one step further and compile glibc ourselves.

This setup might work and is quick as it does not recompile the whole GCC toolchain, just glibc.

But it is not reliable as it uses host C runtime objects such as crt1.o, crti.o, and crtn.o provided by glibc. This is mentioned at: https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location Those objects do early setup that glibc relies on, so I wouldn't be surprised if things crashed in wonderful and awesomely subtle ways.

For a more reliable setup, see Setup 2 below.

Build glibc and install locally:

export glibc_install="$(pwd)/glibc/build/install"

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28
mkdir build
cd build
../configure --prefix "$glibc_install"
make -j `nproc`
make install -j `nproc`

Setup 1: verify the build

test_glibc.c

#define _GNU_SOURCE
#include <assert.h>
#include <gnu/libc-version.h>
#include <stdatomic.h>
#include <stdio.h>
#include <threads.h>

atomic_int acnt;
int cnt;

int f(void* thr_data) {
    for(int n = 0; n < 1000; ++n) {
        ++cnt;
        ++acnt;
    }
    return 0;
}

int main(int argc, char **argv) {
    /* Basic library version check. */
    printf("gnu_get_libc_version() = %s\n", gnu_get_libc_version());

    /* Exercise thrd_create from -pthread,
     * which is not present in glibc 2.27 in Ubuntu 18.04.
     * https://stackoverflow.com/questions/56810/how-do-i-start-threads-in-plain-c/52453291#52453291 */
    thrd_t thr[10];
    for(int n = 0; n < 10; ++n)
        thrd_create(&thr[n], f, NULL);
    for(int n = 0; n < 10; ++n)
        thrd_join(thr[n], NULL);
    printf("The atomic counter is %u\n", acnt);
    printf("The non-atomic counter is %u\n", cnt);
}

Compile and run with test_glibc.sh:

#!/usr/bin/env bash
set -eux
gcc \
  -L "${glibc_install}/lib" \
  -I "${glibc_install}/include" \
  -Wl,--rpath="${glibc_install}/lib" \
  -Wl,--dynamic-linker="${glibc_install}/lib/ld-linux-x86-64.so.2" \
  -std=c11 \
  -o test_glibc.out \
  -v \
  test_glibc.c \
  -pthread \
;
ldd ./test_glibc.out
./test_glibc.out

The program outputs the expected:

gnu_get_libc_version() = 2.28
The atomic counter is 10000
The non-atomic counter is 8674

Command adapted from https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location but --sysroot made it fail with:

cannot find /home/ciro/glibc/build/install/lib/libc.so.6 inside /home/ciro/glibc/build/install

so I removed it.

ldd output confirms that the ldd and libraries that we've just built are actually being used as expected:

+ ldd test_glibc.out
        linux-vdso.so.1 (0x00007ffe4bfd3000)

The gcc compilation debug output shows that my host runtime objects were used, which is bad as mentioned previously, but I don't know how to work around it, e.g. it contains:

COLLECT_GCC_OPTIONS=/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/crt1.o

Setup 1: modify glibc

Now let's modify glibc with:

diff --git a/nptl/thrd_create.c b/nptl/thrd_create.c
index 113ba0d93e..b00f088abb 100644

+#include <stdio.h>
+
 #include "thrd_priv.h"

 int
 thrd_create (thrd_t *thr, thrd_start_t func, void *arg)
 {
+  puts("hacked");
   _Static_assert (sizeof (thr) == sizeof (pthread_t),
                   "sizeof (thr) != sizeof (pthread_t)");

Then recompile and re-install glibc, and recompile and re-run our program:

cd glibc/build
make -j `nproc`
make -j `nproc` install
./test_glibc.sh

and we see hacked printed a few times as expected.

This further confirms that we actually used the glibc that we compiled and not the host one.

Tested on Ubuntu 18.04.

Setup 2: crosstool-NG pristine setup

This is an alternative to setup 1, and it is the most correct setup I've achieved far: everything is correct as far as I can observe, including the C runtime objects such as crt1.o, crti.o, and crtn.o.

In this setup, we will compile a full dedicated GCC toolchain that uses the glibc that we want.

The only downside to this method is that the build will take longer. But I wouldn't risk a production setup with anything less.

crosstool-NG is a set of scripts that downloads and compiles everything from source for us, including GCC, glibc and binutils.

Yes the GCC build system is so bad that we need a separate project for that.

This setup is only not perfect because crosstool-NG does not support building the executables without extra -Wl flags, which feels weird since we've built GCC itself. But everything seems to work, so this is only an inconvenience.

Get crosstool-NG and configure it:

git clone https://github.com/crosstool-ng/crosstool-ng
cd crosstool-ng
git checkout a6580b8e8b55345a5a342b5bd96e42c83e640ac5
export CT_PREFIX="$(pwd)/.build/install"
export PATH="/usr/lib/ccache:${PATH}"
./bootstrap
./configure --enable-local
make -j `nproc`
./ct-ng x86_64-unknown-linux-gnu
./ct-ng menuconfig

The only mandatory option that I can see, is making it match your host kernel version to use the correct kernel headers. Find your host kernel version with:

uname -a

which shows me:

4.15.0-34-generic

so in menuconfig I do:

• Operating System
  • Version of linux

so I select:

4.14.71

which is the first equal or older version. It has to be older since the kernel is backwards compatible.

Now you can build with:

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

and now wait for about thirty minutes to two hours for compilation.

Setup 2: optional configurations

The .config that we generated with ./ct-ng x86_64-unknown-linux-gnu has:

CT_GLIBC_V_2_27=y

To change that, in menuconfig do:

• C-library
• Version of glibc

save the .config, and continue with the build.

Or, if you want to use your own glibc source, e.g. to use glibc from the latest git, proceed like this:

• Paths and misc options
  • Try features marked as EXPERIMENTAL: set to true
• C-library
  • Source of glibc
    • Custom location: say yes
    • Custom location
      • Custom source location: point to a directory containing your glibc source

where glibc was cloned as:

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28

Setup 2: test it out

Once you have built he toolchain that you want, test it out with:

#!/usr/bin/env bash
set -eux
install_dir="${CT_PREFIX}/x86_64-unknown-linux-gnu"
PATH="${PATH}:${install_dir}/bin" \
  x86_64-unknown-linux-gnu-gcc \
  -Wl,--dynamic-linker="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib/ld-linux-x86-64.so.2" \
  -Wl,--rpath="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib" \
  -v \
  -o test_glibc.out \
  test_glibc.c \
  -pthread \
;
ldd test_glibc.out
./test_glibc.out

Everything seems to work as in Setup 1, except that now the correct runtime objects were used:

COLLECT_GCC_OPTIONS=/home/ciro/crosstool-ng/.build/install/x86_64-unknown-linux-gnu/bin/../x86_64-unknown-linux-gnu/sysroot/usr/lib/../lib64/crt1.o

Setup 2: failed efficient glibc recompilation attempt

It does not seem possible with crosstool-NG, as explained below.

If you just re-build;

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

then your changes to the custom glibc source location are taken into account, but it builds everything from scratch, making it unusable for iterative development.

If we do:

./ct-ng list-steps

it gives a nice overview of the build steps:

Available build steps, in order:
  - companion_tools_for_build
  - companion_libs_for_build
  - binutils_for_build
  - companion_tools_for_host
  - companion_libs_for_host
  - binutils_for_host
  - cc_core_pass_1
  - kernel_headers
  - libc_start_files
  - cc_core_pass_2
  - libc
  - cc_for_build
  - cc_for_host
  - libc_post_cc
  - companion_libs_for_target
  - binutils_for_target
  - debug
  - test_suite
  - finish
Use "<step>" as action to execute only that step.
Use "+<step>" as action to execute up to that step.
Use "<step>+" as action to execute from that step onward.

therefore, we see that there are glibc steps intertwined with several GCC steps, most notably libc_start_files comes before cc_core_pass_2, which is likely the most expensive step together with cc_core_pass_1.

In order to build just one step, you must first set the "Save intermediate steps" in .config option for the intial build:

• Paths and misc options
  • Debug crosstool-NG
    • Save intermediate steps

and then you can try:

env -u LD_LIBRARY_PATH time ./ct-ng libc+ -j`nproc`

but unfortunately, the + required as mentioned at: https://github.com/crosstool-ng/crosstool-ng/issues/1033#issuecomment-424877536

Note however that restarting at an intermediate step resets the installation directory to the state it had during that step. I.e., you will have a rebuilt libc - but no final compiler built with this libc (and hence, no compiler libraries like libstdc++ either).

and basically still makes the rebuild too slow to be feasible for development, and I don't see how to overcome this without patching crosstool-NG.

Furthermore, starting from the libc step didn't seem to copy over the source again from Custom source location, further making this method unusable.

Bonus: stdlibc++

A bonus if you're also interested in the C++ standard library: How to edit and re-build the GCC libstdc++ C++ standard library source?

Try with:

select TO_CHAR(dates,'dd/MM/yyy hh24:mi') from (  SELECT min  (TO_DATE(a.PAYM_DATE)) as dates from user_payment a )

"12345".each_char.map(&:to_i)

each_char does basically the same as split(''): It splits a string into an array of its characters.

hmmm, I just realize now that in the original question the string contains commas, so my answer is not really helpful ;-(..

Use

• ps u `pidof $TASKS_LIST` or ps u -C $TASK
• ps xu --sort %mem
• ps h -o pmem -C $TASK

Example:

ps-of()
{
 ps u `pidof "$@"`
}

$ ps-of firefox

Try this way. In your css file change font-family: FontAwesome into font-family: "FontAwesome"; or font-family: 'FontAwesome';. I've solved the same problem using this method.
