do this:
$("tr.item").each(function(i, tr) {
var value = $("span.value", tr).text();
var quantity = $("input.quantity", tr).val();
});

Sample table structure is below and will update from Product_BAK to Product table.
CREATE TABLE [dbo].[Product](
[Id] [int] IDENTITY(1, 1) NOT NULL,
[Name] [nvarchar](100) NOT NULL,
[Description] [nvarchar](100) NULL
) ON [PRIMARY]
CREATE TABLE [dbo].[Product_BAK](
[Id] [int] IDENTITY(1, 1) NOT NULL,
[Name] [nvarchar](100) NOT NULL,
[Description] [nvarchar](100) NULL
) ON [PRIMARY]
update P1
set Name = P2.Name
from Product P1
inner join Product_Bak P2 on p1.id = P2.id
where p1.id = 2
; With CTE as
(
select id, name from Product_Bak where id = 2
)
update P
set Name = P2.name
from product P inner join CTE P2 on P.id = P2.id
where P2.id = 2
Merge into product P1
using Product_Bak P2 on P1.id = P2.id
when matched then
update set p1.[description] = p2.[description], p1.name = P2.Name;
In this Merge statement, we can do inset if not finding a matching record in the target, but exist in the source and please find syntax:
Merge into product P1
using Product_Bak P2 on P1.id = P2.id;
when matched then
update set p1.[description] = p2.[description], p1.name = P2.Name;
WHEN NOT MATCHED THEN
insert (name, description)
values(p2.name, P2.description);
Yes you can...

Update:
I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.
We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.
The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:
Under the hood, HMAC authentication would be:
Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:
User-Agent: {agent}
Host: {host}
Timestamp: {timestamp}
Authentication: {username}:{signature}
Example for GET request:
GET /webapi.hmac/api/values
User-Agent: Fiddler
Host: localhost
Timestamp: Thursday, August 02, 2012 3:30:32 PM
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=
The message to hash to get signature:
GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
Example for POST request with query string (signature below is not correct, just an example)
POST /webapi.hmac/api/values?key2=value2
User-Agent: Fiddler
Host: localhost
Content-Type: application/x-www-form-urlencoded
Timestamp: Thursday, August 02, 2012 3:30:32 PM
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=
key1=value1&key3=value3
The message to hash to get signature
GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
key1=value1&key2=value2&key3=value3
Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.
When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.
The secret key is got from the database with the username on the request.
Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.
The code to build signature:
private static string ComputeHash(string hashedPassword, string message)
{
var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
string hashString;
using (var hmac = new HMACSHA256(key))
{
var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
hashString = Convert.ToBase64String(hash);
}
return hashString;
}
So, how to prevent replay attack?
Add constraint for the timestamp, something like:
servertime - X minutes|seconds <= timestamp <= servertime + X minutes|seconds
(servertime: time of request coming to server)
And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.
The demo code is put as here: https://github.com/cuongle/Hmac.WebApi
Use TextSwitcher
(for nice text transition animation) and timer instead.

Doing this with POSIX is tricky:
POSIX Sed does not support \r

, however the -i inplace
option
is not POSIX
d2u and dos2unix are not POSIX utilities, but ex is
POSIX ex does not support \r

Local server machine: Linux
Accessing machine: iPad 13.5.1
I learned that the local server's host IP needs to be set to 0.0.0.0 for other machines to access it. To check, run sudo netstat -anp
and look for your local server port. I found that it was running on 127.0.0.1 or localhost so other machines weren't able to access it. I changed my app configurations to run on host IP 0.0.0.0. I then used the <internetIP>:<port>
to access the local server, and it worked
Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."
That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.
Why the fuss?

Your error on the snippet of data you posted is a little cryptic, in that because there are no common values, the join operation fails because the values don't overlap it requires you to supply a suffix for the left and right hand side:

Out[173]:

You're in that annoying boundary area where regexps almost won't do (as has been pointed out by Bart, escaping the quotes would make life hard) , and yet a full-blown parser seems like overkill.
If you are likely to need greater complexity any time soon I would go looking for a parser library. For example this one
the most important thing is to analyze how roads, cities, blocks and buildings are structured. find out what all eg buildings have in common. look at photos, maps, plans and reality. if you do that you will be one step ahead of people who consider city building as a merely computer-technological matter.
next you should develop solutions on how to create that geometry in tiny, distinct steps. you have to define rules that make up a believable city. if you are into 3d modelling you have to rethink a lot of what you have learned so the computer can follow your instructions in any situation.
in order to not loose track you should set up a lot of operators that are only responsible for little parts of the whole process. that makes debugging, expanding and improving your system much easier. in the next step you should link those operators and check the results by changing parameters.
i have seen too many "city generators" that mainly consist of random-shaped boxes with some window textures on them : (
this is a bit late.. but i have seen this problem occurs when you want to insert or delete one line from/to DB but u put/pull more than one line or more than one value ,
E.g:
you want to delete one line from DB with a specific value such as id of an item but you've queried a list of ids then you will encounter the same exception message.

Not sure if my answer sounds simple and stupid, and perhaps it has already been known to you since long time ago, but since preventing someone from using browser back button to view your historical pages is one of your goals, you can use:
window.location.replace("https://www.example.com/page-not-to-be-viewed-in-browser-history-back-button.html");
Of course, this may not be possible to be implemented across the entire site, but at least for some critical pages, you can do that. Hope this helps.
echo "blahblah"> txt.txt
will erase the txt and put blahblah in it's place
echo "blahblah">> txt.txt
will write blahblah on a new line in the txt
I think that both will create a new txt if none exists (I know that the first one does)
Where "txt.txt
" is written above, a file path can be inserted if wanted. e.g. C:\Users\<username>\desktop
, which will put it on their desktop.
There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.
The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.
Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.
localStorage
is something that is kept on the client side. There is no data transmitted to the server side.
You can only get the data with JavaScript and you can send it to the server side with Ajax.
You need to explicitly ask for the content type.
Add this line:
request.ContentType = "application/json; charset=utf-8";
At the appropriate place
The following will display all 3 buttons on the same line provided there is enough horizontal space to display them:
<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
// Note the lack of unnecessary divs, floats, etc.
The only reason the buttons wouldn't display inline is if they have had display:block applied to them within your css.
I would favor Abstract Factory over Factory Method anytime. From Tom Dalling's example (great explanation btw) above, we can see that Abstract Factory is more composable in that all we need to do is passing a different Factory to the constructor (constructor dependency injection in use here). But Factory Method requires us to introduce a new class (more things to manage) and use subclassing. Always prefer composition over inheritance.
Usually, we define classes for this.
class XClass( object ):
def __init__( self ):
self.myAttr= None
x= XClass()
x.myAttr= 'magic'
x.myAttr
However, you can, to an extent, do this with the setattr
and getattr
built-in functions. However, they don't work on instances of object
directly.
>>> a= object()
>>> setattr( a, 'hi', 'mom' )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'hi'
They do, however, work on all kinds of simple classes.
class YClass( object ):
pass
y= YClass()
setattr( y, 'myAttr', 'magic' )
y.myAttr
You can return an object of a Class in Java.
If you are returning more than 1 value that are related, then it makes sense to encapsulate them into a class and then return an object of that class.
If you want to return unrelated values, then you can use Java's built-in container classes like Map, List, Set etc. Check the java.util package's JavaDoc for more details.
You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this
import numpy
from matplotlib import pyplot
x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])
fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
ax.annotate(str(j),xy=(i,j))
pyplot.show()
If you want the annotations offset a little, you could change the annotate
line to something like
ax.annotate(str(j),xy=(i,j+0.5))
So I did with
sudo usermod -a -G dialout <my-username>
.
You need to log out after you add yourself to a group so those changes are applied. Just log out and log in again and the menu should be available.
If using Postgres, create sequence manually with name 'hibernate_sequence'. It will work.
I have used the following to add a property with a "dynamic" name to an object:
var key = 'top';
$('#myElement').animate(
(function(o) { o[key]=10; return o;})({left: 20, width: 100}),
10
);
key
is the name of the new property.
The object of properties passed to animate
will be {left: 20, width: 100, top: 10}
This is just using the required []
notation as recommended by the other answers, but with fewer lines of code!
On windows it is easy to interact with your webcam with pygame:

You can use query

b = df.query('a > 1 & a < 5')
Maybe you can try the following without XPath
from simplified_scrapy.simplified_doc import SimplifiedDoc
html = '''

domain in literature without prior coordination or asking for permission.</p>
<p><a href="https://www.iana.org/domains/example">More information...</a></p>
</div>
</body>
</html>
'''
# What XPath can do, so can it
doc = SimplifiedDoc(html)
# The result is the same as doc.getElementByTag('body').getElementByTag('div').getElementByTag('h1').text
print (doc.body.div.h1.text)
print (doc.div.h1.text)
print (doc.h1.text) # Shorter paths will be faster
print (doc.div.getChildren())
print (doc.div.getChildren('p'))
I know that you don't need to trust all certificates but in my case I had problems with some debugging environments where we had self-signed certificates and I needed a dirty solution.
All I had to do was to change the initialization of the sslContext
mySSLContext.init(null, trustAllCerts, null);
where trustAllCerts
was created like this:
private final TrustManager[] trustAllCerts= new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[]{};
}
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
} };
Hope that this will come in handy.
The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression
after all.
I finally came across this nice template for seeing how to execute uninstall strings:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path |
Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} |
ForEach-Object -process {$apps.Set_Item(
$_.getvalue('UninstallString'),
$_.getvalue('DisplayName'))
}
foreach ($uninstall_string in $apps.GetEnumerator()) {
$uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
& $uninstall_app $uninstall_arg
}
This works for me, namely because $app
is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.
Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe
, so there's that too.
You can do this in the following way:
<a href="path to PDF file">Open PDF</a>
If the PDF file is inside some folder and that folder doesn't have permission to access files in that folder directly then you have to bypass some file access restrictions using .htaccess
file setting by this way:
<FilesMatch ".*\.(jpe?g|JPE?G|gif|GIF|png|PNG|swf|SWF|pdf|PDF)$" >
Order Allow,Deny
Allow from all
</FilesMatch>
But now allow just certain necessary files.
I have used this code and it worked perfectly.
Try Ctrl+Alt+Shift+? / ?, without mouse, or hold "alt" and click on all the lines you want.

I had a similar problem using Tomcat against Oracle. I DID have the context.xml in the META-INF directory, on the disc. This file was not showing in the eclipse project though. A simple hit on the F5 refresh and the context.xml file appeared and eclipse published it. Everything worked past that. Hope this helps someone.
Try hitting F5 in eclipse
The C++ way would be to use a std::stringstream
object as:
std::stringstream fmt;
fmt << a << " " << b << " > " << c;
The C way would be to use sprintf
.
The C way is difficult to get right since:
Of course, you may want to fall back on the C way if performance is an issue (imagine you are creating fixed-size million little stringstream
objects and then throwing them away).
A lot of people, including me, use sqlfiddle.com to test SQL.

if (property_exists($ob, 'a'))
if (isset($ob->a))
isset() will return false if property is null
Example 1:
$ob->a = null
var_dump(isset($ob->a)); // false
Example 2:
class Foo
{
public $bar = null;
}
$foo = new Foo();
var_dump(property_exists($foo, 'bar')); // true
var_dump(isset($foo->bar)); // false
The else
case is unncecessary, when you create a string
object it is empty by default.
I solve that with putting this at the end of my app module build.gradle:
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '26.0.0'
}
}
}
}
Using Spring's SimpleJdbcTemplate, I got it when I tried to do this:
String sqlString = "select pwy_code from approver where university_id = '123'";
List<Map<String, Object>> rows = getSimpleJdbcTemplate().queryForList(sqlString, uniId);
I had an argument to queryForList that didn't correspond to a question mark in the SQL. The first line should have been:
String sqlString = "select pwy_code from approver where university_id = ?";
Above all, I can't solve it. But I add file to /usr/local/include solve it.

In /usr/local/include, add a my_config.h file.
Then pip install MySQL-Python

Both styles, with a touch of tweaking, would work.
The first method uses a Javascript Constructor, which like most things has pros and cons.
// By convention, constructors start with an upper case letter
function MakePerson(name,age) {
// The magic variable 'this' is set by the Javascript engine and points to a newly created object that is ours.
this.name = name;
this.age = age;
this.occupation = "Hobo";
}
var jeremy = new MakePerson("Jeremy", 800);
On the other hand, your other method is called the 'Revealing Closure Pattern' if I recall correctly.
function makePerson(name2, age2) {
var name = name2;
var age = age2;
return {
name: name,
age: age
};
}
Even if fileno(FILE *)
may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.
To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)
If you are using MySQL 8.0.11 so, you need to remove the ’NO_AUTO_CREATE_USER‘ from sql-mode.
Add following line in file /etc/mysql/my.cnf
and [mysqld] header

sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
Simple and easy way to see database content within Android studio.
You can use a very simple Android Studio's feature Database Inspector. Where you can inspect, query, and modify your app’s databases using the new Database Inspector. For example, you can debug your running app by modifying values in your database and testing those changes on the device in real-time without leaving Android Studio.
To get started, deploy your app to a device running API level 26 or higher and select View > Tool Windows > Database Inspector from the menu bar.
First, install Database Navigator plugin in Android Studio
Second, Restart Android Studio
Third, save the database into the default location like: (C:\Users\User Name\Documents\AndroidStudio\DeviceExplorer\emulator or device\data\data\package name\databases)
Fourth, Connect saved dbname_db file in Database Navigator
Give same DB file path that is used in step Third
i.e (C:\Users\User Name\Documents\AndroidStudio\DeviceExplorer\emulator or device\data\data\package name\databases\package naem\dbname_db)
Finally, just test DB connection and open console and do whatever you want to do.
If you want to refresh DB just repeat step Second and just save it or refresh.

width: 145px;
padding-top: 80px;
}?
Your code isn't working, because the hidden attibute is not supported in versions of IE before v11
If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:
*[hidden] { display: none; }
I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.
Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).
You could use the T4 templating mechanism in Visual Studio to generate the required source code from a simple text file :
I wanted to configure version information generation for some .NET projects. It’s been a long time since I investigated available options, so I searched around hoping to find some simple way of doing this. What I’ve found didn’t look very encouraging: people write Visual Studio add-ins and custom MsBuild tasks just to obtain one integer number (okay, maybe two). This felt overkill for a small personal project.
The inspiration came from one of the StackOverflow discussions where somebody suggested that T4 templates could do the job. And of course they can. The solution requires a minimal effort and no Visual Studio or build process customization. Here what should be done:
- Create a file with extension ".tt" and place there T4 template that will generate AssemblyVersion and AssemblyFileVersion attributes:
<#@ template language="C#" #>
//
// This code was generated by a tool. Any changes made manually will be lost
// the next time this code is regenerated.
//
using System.Reflection;
[assembly: AssemblyVersion("1.0.1.<#= this.RevisionNumber #>")]
[assembly: AssemblyFileVersion("1.0.1.<#= this.RevisionNumber #>")]
<#+
int RevisionNumber = (int)(DateTime.UtcNow - new DateTime(2010,1,1)).TotalDays;
#>
You will have to decide about version number generation algorithm. For me it was sufficient to auto-generate a revision number that is set to the number of days since January 1st, 2010. As you can see, the version generation rule is written in plain C#, so you can easily adjust it to your needs.
- The file above should be placed in one of the projects. I created a new project with just this single file to make version management technique clear. When I build this project (actually I don’t even need to build it: saving the file is enough to trigger a Visual Studio action), the following C# is generated:
//
// This code was generated by a tool. Any changes made manually will be lost
// the next time this code is regenerated.
//
using System.Reflection;
[assembly: AssemblyVersion("1.0.1.113")]
[assembly: AssemblyFileVersion("1.0.1.113")]
Yes, today it’s 113 days since January 1st, 2010. Tomorrow the revision number will change.
- Next step is to remove AssemblyVersion and AssemblyFileVersion attributes from AssemblyInfo.cs files in all projects that should share the same auto-generated version information. Instead choose “Add existing item” for each projects, navigate to the folder with T4 template file, select corresponding “.cs” file and add it as a link. That will do!
What I like about this approach is that it is lightweight (no custom MsBuild tasks), and auto-generated version information is not added to source control. And of course using C# for version generation algorithm opens for algorithms of any complexity.
Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0)))
. This simulates the ELSE-IF
operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF
formula is the value to use if the condition evaluates to true
. You can't chain conditions in that manner.
I think this way is easy:
>>> bytes_data = [112, 52, 52]
>>> "".join(map(chr, bytes_data))
'p44'
Depending on where you need that and how to access the object there are different ways to do it.
For example: just typecast it
$object = (object) $yourArray;
However, the most compatible one is using a utility method (not yet part of PHP) that implements standard PHP casting based on a string that specifies the type (or by ignoring it just de-referencing the value):
/**
* dereference a value and optionally setting its type
*
* @param mixed $mixed
* @param null $type (optional)
*
* @return mixed $mixed set as $type
*/
function rettype($mixed, $type = NULL) {
$type === NULL || settype($mixed, $type);
return $mixed;
}
The usage example in your case (Online Demo):
$yourArray = Array('status' => 'Figure A. ...');
echo rettype($yourArray, 'object')->status; // prints "Figure A. ..."
Your response should be something like this to be qualified as Json Array.
{
"songs":[
{"2562862600": {"id":"2562862600", "pos":1}},
{"2562862620": {"id":"2562862620", "pos":1}},
{"2562862604": {"id":"2562862604", "pos":1}},
{"2573433638": {"id":"2573433638", "pos":1}}
]
}
You can parse your response as follows
String resp = ...//String output from your source
JSONObject ob = new JSONObject(resp);
JSONArray arr = ob.getJSONArray("songs");
for(int i=0; i<arr.length(); i++){
JSONObject o = arr.getJSONObject(i);
System.out.println(o);
}
Here's a simple example in C++11.
#include <mutex> // mutex
#include <iostream> // cout
#include <cstdio> // getchar
#include <thread> // this_thread, yield
#include <future> // async
#include <chrono> // seconds
using namespace std;
mutex _m1;
mutex _m2;
// Deadlock will occur because func12 and func21 acquires the two locks in reverse order
void func12()
{
unique_lock<mutex> l1(_m1);
this_thread::yield(); // hint to reschedule
this_thread::sleep_for( chrono::seconds(1) );
unique_lock<mutex> l2(_m2 );
}
void func21()
{
unique_lock<mutex> l2(_m2);
this_thread::yield(); // hint to reschedule
this_thread::sleep_for( chrono::seconds(1) );
unique_lock<mutex> l1(_m1);
}
int main( int argc, char* argv[] )
{
async(func12);
func21();
cout << "All done!"; // this won't be executed because of deadlock
getchar();
}
use this too :
if(e.preventDefault)
e.preventDefault();
else
e.returnValue = false;
Becoz e.preventDefault() is not supported in IE( some versions ). In IE it is e.returnValue = false
First of all, you really should be including the position on absolutely positioned elements or you will come across odd and confusing behavior; you probably want to add top: 0; left: 0
to the CSS for both of your absolutely positioned elements. You'll also want to have position: relative
on .container_row
if you want the absolutely positioned elements to be positioned with respect to their parent rather than the document's body:
If the element has 'position: absolute', the containing block is established by the nearest ancestor with a 'position' of 'absolute', 'relative' or 'fixed' ...
Your problem is that position: absolute
removes elements from the normal flow:
It is removed from the normal flow entirely (it has no impact on later siblings). An absolutely positioned box establishes a new containing block for normal flow children and absolutely (but not fixed) positioned descendants. However, the contents of an absolutely positioned element do not flow around any other boxes.
This means that absolutely positioned elements have no effect whatsoever on their parent element's size and your first <div class="container_row">
will have a height of zero.
So you can't do what you're trying to do with absolutely positioned elements unless you know how tall they're going to be (or, equivalently, you can specify their height). If you can specify the heights then you can put the same heights on the .container_row
and everything will line up; you could also put a margin-top
on the second .container_row
to leave room for the absolutely positioned elements. For example:
I think its worth referencing this similar answer: https://stackoverflow.com/a/5288804/64313
Here is a another quick solution. There are other variations possible on this using the <available>
tag:
# exit with failure if no files are found
<property name="file" value="${some.path}/some.txt" />
<fail message="FILE NOT FOUND: ${file}">
<condition><not>
<available file="${file}" />
</not></condition>
</fail>
Update: Subversion 1.9 will support a new command "svn youngest" that outputs only the latest revision number. The difference to "svnlook youngest" is that "svn youngest" also works remotely.
color
and fill
are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:
d + scale_color_manual(values=c("#CC6666", "#9999CC"))
is what you want.
To extract the real part of a complex-valued expression z
, use the notation as __real__ z
.
Similarly, use __imag__
attribute on the z
to extract the imaginary part.
For example;
__complex__ float z;
float r;
float i;
r = __real__ z;
i = __imag__ z;
r is the real part of the complex number "z" i is the imaginary part of the complex number "z"
Don't forget to add sudo
otherwise you will get postman.tar.gz: Permission denied
error.
And unlink postman if you get error like failed to create symbolic link
/usr/bin/postman
: File exists.
So below is the full code:
sudo wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz
sudo tar -xzf postman.tar.gz -C /opt
sudo rm postman.tar.gz
sudo unlink /usr/bin/postman
sudo ln -s /opt/Postman/Postman /usr/bin/postman
Then just run postman in the terminal.
The Sun page you link to has some key differences between the two:
A nested class is a member of its enclosing class. Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private. Static nested classes do not have access to other members of the enclosing class.
...Note: A static nested class interacts with the instance members of its outer class (and other classes) just like any other top-level class. In effect, a static nested class is behaviorally a top-level class that has been nested in another top-level class for packaging convenience.
There is no need for LinkedList.Entry
to be top-level class as it is only used by LinkedList
(there are some other interfaces that also have static nested classes named Entry
, such as Map.Entry
- same concept). And since it does not need access to LinkedList's members, it makes sense for it to be static - it's a much cleaner approach.
As Jon Skeet points out, I think it is a better idea if you are using a nested class is to start off with it being static, and then decide if it really needs to be non-static based on your usage.
I have debian 9 and to fix this i used the new library as follows:
ln -s /usr/bin/gpgv /usr/bin/gnupg2
You could add
cd /some/directory/somewhere/named/Foo
to your .bashrc
file (or .profile
or whatever you call it) at the other host. That way, no matter what you do or where you ssh
from, whenever you log onto that server, it will cd
to the proper directory for you, and all you have to do is use ssh
like normal.
Of curse, rogeriopvl's solution works too, but it's a tad bit more verbose, and you have to remember to do it every time (unless you make an alias) so it seems a bit less "fun".
From GC Performance Tuning training documents of Oracle:
-Xmn[size]: Size of young generation heap space.
Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.
In short, it sets the NewSize and MaxNewSize values of New generation to the same value.

mysqli_error()
As in:
$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);
Trigger error is better than die because you can use it for development AND production, it's the permanent solution.
well, char *
means a pointer point to char, it is different from char array.
char amessage[] = "this is an array"; /* define an array*/
char *pmessage = "this is a pointer"; /* define a pointer*/
And, char **
means a pointer point to a char pointer.
You can look some books about details about pointer and array.
This one-liner tells where the shell script is, does not matter if you ran it or if you sourced it. Also, it resolves any symbolic links involved, if that is the case:
dir=$(dirname $(test -L "$BASH_SOURCE" && readlink -f "$BASH_SOURCE" || echo "$BASH_SOURCE"))
By the way, I suppose you are using /bin/bash.
i had the same problem and was already using the code in the selected answer. this link was the answer for me; maybe for others also.
If you're using Xamarin, I found a guide on their official forum explaining how to do this:
Hereafter, you might also need to update the Google Play Services from the Google Play Store.
Hope this helps for anyone else who has troubles finding the documentation.
You can also use the following syntax for the strongly typed version:
<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(),
FormMethod.Post,
new { enctype = "multipart/form-data" }))
{ %>
Try this;
string.Format(new CultureInfo("en-SG", false), "{0:c0}", 123423.083234);
It will convert 123423.083234 to $1,23,423 format.
Please find the code in jsFiddle. It uses jQuery to modify the href of the link. You can use any other library in its place. It should work.

Having tried $customer = new WC_Customer();
and global $woocommerce; $customer = $woocommerce->customer;
I was still getting empty address data even when I logged in as a non-admin user.
My solution was as follows:
function mwe_get_formatted_shipping_name_and_address($user_id) {
$address = '';
$address .= get_user_meta( $user_id, 'shipping_first_name', true );
$address .= ' ';
$address .= get_user_meta( $user_id, 'shipping_last_name', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_company', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_address_1', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_address_2', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_city', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_state', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_postcode', true );
$address .= "\n";
$address .= get_user_meta( $user_id, 'shipping_country', true );
return $address;
}
...and this code works regardless of whether you are logged in as admin or not.
With TypeScript generics you can do something like this.
class Person {
constructor (public Name : string, public Age: number) {}
}
var list = new Array<Person>();
list.push(new Person("Baby", 1));
list.push(new Person("Toddler", 2));
list.push(new Person("Teen", 14));
list.push(new Person("Adult", 25));
var oldest_person = list.reduce( (a, b) => a.Age > b.Age ? a : b );
alert(oldest_person.Name);
Another use is to split the implementation of different interfaces, e.g:
partial class MyClass : IF3
{
// main implementation of MyClass
}
partial class MyClass : IF1
{
// implementation of IF1
}
partial class MyClass : IF2
{
// implementation of IF2
}
In many situations, a custom attribute attached to a pd.DataFrame
object is not necessary. In addition, note that pandas
-object attributes may not serialize. So pickling will lose this data.
Instead, consider creating a dictionary with appropriately named keys and access the dataframe via dfs['some_label']
.
df = pd.DataFrame()
dfs = {'some_label': df}

The native JSON object includes two key methods.
1. JSON.parse()
2. JSON.stringify()
The JSON.parse()
method parses a JSON string - i.e. reconstructing the original JavaScript object
var jsObject = JSON.parse(jsonString);
JSON.stringify() method accepts a JavaScript object and returns its JSON equivalent.
var jsonString = JSON.stringify(jsObject);
Arithmetic operations involving float
results in float
.
int + float = float
int * float = float
float * int = float
int / float = float
float / int = float
int / int = int
For more detail answer. Look at what the section §5/9 from the C++ Standard says
Many binary operators that expect operands of arithmetic or enumeration type cause conversions and yield result types in a similar way. The purpose is to yield a common type, which is also the type of the result.
This pattern is called the usual arithmetic conversions, which are defined as follows:
— If either operand is of type long double, the other shall be converted to long double.
— Otherwise, if either operand is double, the other shall be converted to double.
— Otherwise, if either operand is float, the other shall be converted to float.
— Otherwise, the integral promotions (4.5) shall be performed on both operands.54)
— Then, if either operand is unsigned long the other shall be converted to unsigned long.
— Otherwise, if one operand is a long int and the other unsigned int, then if a long int can represent all the values of an unsigned int, the unsigned int shall be converted to a long int; otherwise both operands shall be converted to unsigned long int.
— Otherwise, if either operand is long, the other shall be converted to long.
— Otherwise, if either operand is unsigned, the other shall be converted to unsigned.
[Note: otherwise, the only remaining case is that both operands are int ]
With .NET 4.0 You can add the HandleProcessCorruptedStateExceptions
attribute from System.Runtime.ExceptionServices to the method containing the try/catch block. This really worked! Maybe not recommended but works.

}
}
class Program
{
[HandleProcessCorruptedStateExceptions]
static void Main(string[] args)
{
Test test = new Test();
try {
//test.StackOverflow();
test.AccessViolation();
//test.CustomException();
}
catch
{
Console.WriteLine("Caught.");
}
Console.WriteLine("End of program");
}
}
}
You can use react-pure-lifecycle to add lifecycle functions to functional components.
Example:
import React, { Component } from 'react';
import lifecycle from 'react-pure-lifecycle';
const methods = {
componentDidMount(props) {
console.log('I mounted! Here are my props: ', props);
}
};
const Channels = props => (
<h1>Hello</h1>
)
export default lifecycle(methods)(Channels);
=CDate(Now).ToString("dd/MM/yyyy")
Although you are hardcoding the date formart to a locale.

POSIX 7 quotes
POSIX 7 specifies both at http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html:
CLOCK_REALTIME
:
This clock represents the clock measuring real time for the system. For this clock, the values returned by clock_gettime() and specified by clock_settime() represent the amount of time (in seconds and nanoseconds) since the Epoch.
CLOCK_MONOTONIC
(optional feature):
For this clock, the value returned by clock_gettime() represents the amount of time (in seconds and nanoseconds) since an unspecified point in the past (for example, system start-up time, or the Epoch). This point does not change after system start-up time. The value of the CLOCK_MONOTONIC clock cannot be set via clock_settime().
clock_settime()
gives an important hint: POSIX systems are able to arbitrarily change CLOCK_REALITME
with it, so don't rely on it flowing neither continuously nor forward. NTP could be implemented using clock_settime()
, and could only affect CLOCK_REALITME
.
The Linux kernel implementation seems to take boot time as the epoch for CLOCK_MONOTONIC
: Starting point for CLOCK_MONOTONIC

Suppose company C offers product P and P involves software in some way. Then C can offer a library/set of libraries to software developers that drive P's software systems.
That library/libraries are an SDK. It is part of the systems of P. It is a kit for software developers to use in order to modify, configure, fix, improve, etc the software piece of P.
If C wants to offer P's functionality to other companies/systems, it does so with an API.
This is an interface to P. A way for external systems to interact with P.
If you think in terms of implementation, they will seem quite similar. Especially now that the internet has become like one large distributed operating system.
In purpose, though, they are actually quite distinct.
You build something with an SDK and you use or consume something with an API.
For enterprise applications it should be noted that you should not be handling https in your code. It should be auto upgraded via IIS or nginx. The app shouldn't know about what protocols are used.

No need for array. Just use something like this:
Sub ARRAYER()

Dim Number_of_Sims As Long
Dim i As Long
Number_of_Sims = 10
Set Rng = Range("C4:G4")
For i = 1 To Number_of_Sims
Rng.Offset(i, 0).Value = Rng.Value

String
is immutable
i.e. strings cannot be altered. When you alter a string (by adding to it for example), you are actually creating a new string.
But StringBuilder
is not immutable (rather, it is mutable)
so if you have to alter a string many times, such as multiple concatenations, then use StringBuilder
.

Just make sure nothing is actually written to the page prior to this code, or it won't work.
EncodeAndSend
is not a static function, which means it can be called on an instance of the class CPMSifDlg
. You cannot write this:
CPMSifDlg::EncodeAndSend(/*...*/); //wrong - EncodeAndSend is not static
It should rather be called as:
CPMSifDlg dlg; //create instance, assuming it has default constructor!
dlg.EncodeAndSend(/*...*/); //correct
You need to set the flags after the project
command in your CMakeLists.txt.
Also, if you're calling include(${QT_USE_FILE})
or add_definitions(${QT_DEFINITIONS})
, you should include these set
commands after the Qt ones since these would append further flags. If that is the case, you maybe just want to append your flags to the Qt ones, so change to e.g.
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O0 -ggdb")
Adding to all the answers here, I thought to mention, a very specific reason/scenario where you might want to prefer to throw the exception from the class's Init
method and not from the Ctor (which off course is the preferred and more common approach).
I will mention in advance that this example (scenario) assumes that you don't use "smart pointers" (i.e.- std::unique_ptr
) for your class'
s pointer(s) data members.
So to the point: In case, you wish that the Dtor of your class will "take action" when you invoke it after (for this case) you catch the exception that your Init()
method threw - you MUST not throw the exception from the Ctor, cause a Dtor invocation for Ctor's are NOT invoked on "half-baked" objects.
See the below example to demonstrate my point:
#include <iostream>
using namespace std;
class A
{
public:
A(int a)
: m_a(a)
{
cout << "A::A - setting m_a to:" << m_a << endl;
}
~A()
{
cout << "A::~A" << endl;
}
int m_a;
};
class B
{
public:
B(int b)
: m_b(b)
{
cout << "B::B - setting m_b to:" << m_b << endl;
}
~B()
{
cout << "B::~B" << endl;
}
int m_b;
};
class C
{
public:
C(int a, int b, const string& str)
: m_a(nullptr)
, m_b(nullptr)
, m_str(str)
{
m_a = new A(a);
cout << "C::C - setting m_a to a newly A object created on the heap (address):" << m_a << endl;
if (b == 0)
{
throw exception("sample exception to simulate situation where m_b was not fully initialized in class C ctor");
}
m_b = new B(b);
cout << "C::C - setting m_b to a newly B object created on the heap (address):" << m_b << endl;
}
~C()
{
delete m_a;
delete m_b;
cout << "C::~C" << endl;
}
A* m_a;
B* m_b;
string m_str;
};
class D
{
public:
D()
: m_a(nullptr)
, m_b(nullptr)
{
cout << "D::D" << endl;
}
void InitD(int a, int b)
{
cout << "D::InitD" << endl;
m_a = new A(a);
throw exception("sample exception to simulate situation where m_b was not fully initialized in class D Init() method");
m_b = new B(b);
}
~D()
{
delete m_a;
delete m_b;
cout << "D::~D" << endl;
}
A* m_a;
B* m_b;
};
void item10Usage()
{
cout << "item10Usage - start" << endl;
// 1) invoke a normal creation of a C object - on the stack
// Due to the fact that C's ctor throws an exception - its dtor
// won't be invoked when we leave this scope
{
try
{
C c(1, 0, "str1");
}
catch (const exception& e)
{
cout << "item10Usage - caught an exception when trying to create a C object on the stack:" << e.what() << endl;
}
}
// 2) same as in 1) for a heap based C object - the explicit call to
// C's dtor (delete pc) won't have any effect
C* pc = 0;
try
{
pc = new C(1, 0, "str2");
}
catch (const exception& e)
{
cout << "item10Usage - caught an exception while trying to create a new C object on the heap:" << e.what() << endl;
delete pc; // 2a)
}
// 3) Here, on the other hand, the call to delete pd will indeed
// invoke D's dtor
D* pd = new D();
try
{
pd->InitD(1,0);
}
catch (const exception& e)
{
cout << "item10Usage - caught an exception while trying to init a D object:" << e.what() << endl;
delete pd;
}
cout << "\n \n item10Usage - end" << endl;
}
int main(int argc, char** argv)
{
cout << "main - start" << endl;
item10Usage();
cout << "\n \n main - end" << endl;
return 0;
}
I will mention again, that it is not the recommended approach, just wanted to share an additional point of view.
Also, as you might have seen from some of the print in the code - it is based on item 10 in the fantastic "More effective C++" by Scott Meyers (1st edition).
Yes , A plugin is available named "combine" for notepad++.Link: .>> Combine Plugin for Notepad++
You can install it via plugin manager. Extra benifit of this plugin is: "You can maintain the sequence of files while merging, it's according to the sequence of opened files are opened (see tabs)".
Retrieve the ID of the current item in the WordPress Loop.
echo get_the_ID();
hence works for the product id too. #tested #woo-commerce
If you want to modify only the first commit, you may try git rebase and amend the commit, which is similar to this post: How to modify a specified commit in git?
And if you want to modify all the commits which contain the raw email, filter-branch is the best choice. There is an example of how to change email address globally on the book Pro Git, and you may find this link useful http://git-scm.com/book/en/Git-Tools-Rewriting-History
From the command line:
psql -f 1.sql
psql -f 2.sql
From the psql
prompt:
\i 1.sql
\i 2.sql
Note that you may need to import the files in a specific order (for example: data definition before data manipulation). If you've got bash
shell (GNU/Linux, Mac OS X, Cygwin) and the files may be imported in the alphabetical order, you may use this command:
for f in *.sql ; do psql -f $f ; done

I'd start by not calling it list
, since that's the name of the constructor for Python's built in list
type.
But once you've renamed it to cities
or something, you'd do:
print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])
With a Spring Boot one can do the following:

@Component
@ConfigurationProperties
public class Configuration {
List<String> values = new ArrayList<>();
public List<String> getValues() {
return values;

}
This is needed, without this class or without the values
in class it is not working.

So many ways to skin this cat. You can do this in a closure. This code will give you a read-only , namespaced way to have constants. Just declare them in the Public area.
//Namespaced Constants
var MyAppName;
//MyAppName Namespace
(function (MyAppName) {
//MyAppName.Constants Namespace
(function (Constants) {
//Private
function createConstant(name, val) {
Object.defineProperty(MyAppName.Constants, name, {
value: val,
writable: false
});
}
//Public
Constants.FOO = createConstant("FOO", 1);
Constants.FOO2 = createConstant("FOO2", 1);
MyAppName.Constants = Constants;
})(MyAppName.Constants || (MyAppName.Constants = {}));
})(MyAppName || (MyAppName = {}));
Usage:
console.log(MyAppName.Constants.FOO); //prints 1
MyAppName.Constants.FOO = 2;
console.log(MyAppName.Constants.FOO); //does not change - still prints 1
<h1><span>This is</span> a Headline</h1>
h1 { font-weight: normal; text-transform: uppercase; }
h1 span { font-weight: bold; }
I'm not sure if it was just for the sake of showing us, but as a side note, you should always set uppercase text with CSS :)

replace:true
is DeprecatedFrom the Docs:
replace

false
.
true
- the template will replace the directive's element.false
- the template will replace the contents of the directive's element.
-- AngularJS Comprehensive Directive API
From GitHub:
Caitp-- It's deprecated because there are known, very silly problems with
replace: true
, a number of which can't really be fixed in a reasonable fashion. If you're careful and avoid these problems, then more power to you, but for the benefit of new users, it's easier to just tell them "this will give you a headache, don't do it".
Note:
replace: true
is deprecated and not recommended to use, mainly due to the issues listed here. It has been completely removed in the new Angular.

If you set CURLOPT_RETURNTRANSFER
to true
or 1
then the return value from curl_exec
will be the actual result from the successful operation. In other words it will not return TRUE
on success. Although it will return FALSE
on failure.
As described in the Return Values section of curl-exec
PHP manual page: http://php.net/manual/function.curl-exec.php
You should enable the CURLOPT_FOLLOWLOCATION
option for redirects but this would be a problem if your server is in safe_mode
and/or open_basedir
is in effect which can cause issues with curl as well.

If, running an Oracle HotSpot JDK 1.7.x, on a Linux platform where your locale suggests UTF-8 (e.g. LANG=en_US.utf8
), if you don't set it on the command-line with -Dfile.encoding
, the JDK will default file.encoding
and the default Charset
like this:
System.out.println(String.format("file.encoding: %s", System.getProperty("file.encoding")));
System.out.println(String.format("defaultCharset: %s", Charset.defaultCharset().name()));
... yields:
file.encoding: UTF-8
defaultCharset: UTF-8
... suggesting the default is UTF-8
on such a platform.
Additionally, if java.nio.charset.Charset.defaultCharset()
finds file.encoding
not-set, it looks for java.nio.charset.Charset.forName("UTF-8")
, suggesting it prefers that string, although it is well-aliased, so "UTF8" will also work fine.
If you run the same program on the same platform with java -Dfile.encoding=UTF8
, without the hypen, it yields:
file.encoding: UTF8
defaultCharset: UTF-8
... noting that the default charset has been canonicalized from UTF8
to UTF-8
.
SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.

Here is a handy function you can use to help with identifying your opencv matrices at runtime. I find it useful for debugging, at least.
string type2str(int type) {
string r;
uchar depth = type & CV_MAT_DEPTH_MASK;
uchar chans = 1 + (type >> CV_CN_SHIFT);
switch ( depth ) {
case CV_8U: r = "8U"; break;
case CV_8S: r = "8S"; break;
case CV_16U: r = "16U"; break;
case CV_16S: r = "16S"; break;
case CV_32S: r = "32S"; break;
case CV_32F: r = "32F"; break;
case CV_64F: r = "64F"; break;
default: r = "User"; break;
}
r += "C";
r += (chans+'0');
return r;
}
If M
is a var of type Mat
you can call it like so:
string ty = type2str( M.type() );
printf("Matrix: %s %dx%d \n", ty.c_str(), M.cols, M.rows );
Will output data such as:
Matrix: 8UC3 640x480
Matrix: 64FC1 3x2
Its worth noting that there are also Matrix methods Mat::depth()
and Mat::channels()
. This function is just a handy way of getting a human readable interpretation from the combination of those two values whose bits are all stored in the same value.

From the article Override equals and hashCode in Java:
Default implementation of equals() class provided by java.lang.Object compares memory location and only return true if two reference variable are pointing to same memory location i.e. essentially they are same object.
Java recommends to override equals and hashCode method if equality is going to be defined by logical way or via some business logic: example:
many classes in Java standard library does override it e.g. String overrides equals, whose implementation of equals() method return true if content of two String objects are exactly same
Integer wrapper class overrides equals to perform numerical comparison etc.

Beside rowid, you can define your own auto increment field but it is not recommended. It is always be better solution when we use rowid that is automatically increased.
The
AUTOINCREMENT
keyword imposes extra CPU, memory, disk space, and disk I/O overhead and should be avoided if not strictly needed. It is usually not needed.

Try this::
sb_trim = Regex.Replace(stw, @"(\D+)\s+\$([\d,]+)\.\d+\s+(.)",
m => string.Format(
"{0},{1},{2}",
m.Groups[1].Value,
m.Groups[2].Value.Replace(",", string.Empty),
m.Groups[3].Value));
This is about as clean an answer as you'll get, at least with regexes.
(\D+)
: First capture group. One or more non-digit characters.\s+\$
: One or more spacing characters, then a literal dollar sign ($).([\d,]+)
: Second capture group. One or more digits and/or commas.\.\d+
: Decimal point, then at least one digit.\s+
: One or more spacing characters.(.)
: Third capture group. Any non-line-breaking character.The second capture group additionally needs to have its commas stripped. You could do this with another regex, but it's really unnecessary and bad for performance. This is why we need to use a lambda expression and string format to piece together the replacement. If it weren't for that, we could just use this as the replacement, in place of the lambda expression:
"$1,$2,$3"
^
matches position just before the first character of the string$
matches position just after the last character of the string.
matches a single character. Does not matter what character it is, except newline*
matches preceding match zero or more timesSo, ^.*$
means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.
Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones
and Matthew's last name is Jones
. The pattern ^Matt.*Jones$
will match Matthew's last name is Jones
. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.
Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.

I might be a little late to the game here, but using coalesce(1)
or repartition(1)
may work for small data-sets, but large data-sets would all be thrown into one partition on one node. This is likely to throw OOM errors, or at best, to process slowly.
I would highly suggest that you use the FileUtil.copyMerge()
function from the Hadoop API. This will merge the outputs into a single file.
EDIT - This effectively brings the data to the driver rather than an executor node. Coalesce()
would be fine if a single executor has more RAM for use than the driver.
EDIT 2: copyMerge()
is being removed in Hadoop 3.0. See the following stack overflow article for more information on how to work with the newest version: How to do CopyMerge in Hadoop 3.0?

Just check your php.ini file, In this file Semicolon(;) used for comment if you see then remove semicolon ;.
;extension=mysql.dll
Now your extension is enable but you need to restart appache
extension=mysql.dll
It is possible the other branch you try to pull from is out of synch; so before adding and removing remote try to (if you are trying to pull from master)
git pull origin master
for me that simple call solved those error messages:
If you're using jQuery 2.1.4 or above, try this:
$("#" + this.d);
Or, you can define var before using it. It makes your code simpler.
var d = this.d
$("#" + d);
enum A { foo, bar } a;
a = foo;
printf( "%d", a ); // see comments below
This question seems to be the most popular one for disabling textarea
wrap. However, as of April 2017 I find that IE 11 (11.0.9600) will not disable word wrap with any of the above solutions.
The only solution which does work for IE 11 is wrap="off"
. wrap="soft"
and/or the various CSS attributes like white-space: pre
alter where IE 11 chooses to wrap but it still wraps somewhere. Note that I have tested this with or without Compatibility View. IE 11 is pretty HTML 5 compatible, but not in this case.
Thus, to achieve lines which retain their whitespace and go off the right-hand side I am using:
<textarea style="white-space: pre; overflow: scroll;" wrap="off">
Fortuitously this does seem to work in Chrome & Firefox too. I am not defending the use of pre-HTML 5 wrap="off"
, just saying that it seems to be required for IE 11.
I found a pretty simple way to do this. Use a button to open it using an on click
listener to start the function openc()
, like this:
String fileloc;
private void openc()
{
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = null;
try
{
f = File.createTempFile("temppic",".jpg",getApplicationContext().getCacheDir());
if (takePictureIntent.resolveActivity(getPackageManager()) != null)
{
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,FileProvider.getUriForFile(profile.this, BuildConfig.APPLICATION_ID+".provider",f));
fileloc = Uri.fromFile(f)+"";
Log.d("texts", "openc: "+fileloc);
startActivityForResult(takePictureIntent, 3);
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 3 && resultCode == RESULT_OK) {
Log.d("texts", "onActivityResult: "+fileloc);
// fileloc is the uri of the file so do whatever with it
}
}
You can do whatever you want with the uri
location string. For instance, I send it to an image cropper to crop the image.
This is the complex (curly) syntax for string interpolation. From the manual:
Complex (curly) syntax
This isn't called complex because the syntax is complex, but because it allows for the use of complex expressions.
Any scalar variable, array element or object property with a string representation can be included via this syntax. Simply write the expression the same way as it would appear outside the string, and then wrap it in
{
and}
. Since{
can not be escaped, this syntax will only be recognised when the$
immediately follows the{
. Use{\$
to get a literal{$
. Some examples to make it clear:<?php // Show all errors error_reporting(E_ALL); $great = 'fantastic'; // Won't work, outputs: This is { fantastic} echo "This is { $great}"; // Works, outputs: This is fantastic echo "This is {$great}"; echo "This is ${great}"; // Works echo "This square is {$square->width}00 centimeters broad."; // Works, quoted keys only work using the curly brace syntax echo "This works: {$arr['key']}"; // Works echo "This works: {$arr[4][3]}"; // This is wrong for the same reason as $foo[bar] is wrong outside a string. // In other words, it will still work, but only because PHP first looks for a // constant named foo; an error of level E_NOTICE (undefined constant) will be // thrown. echo "This is wrong: {$arr[foo][3]}"; // Works. When using multi-dimensional arrays, always use braces around arrays // when inside of strings echo "This works: {$arr['foo'][3]}"; // Works. echo "This works: " . $arr['foo'][3]; echo "This works too: {$obj->values[3]->name}"; echo "This is the value of the var named $name: {${$name}}"; echo "This is the value of the var named by the return value of getName(): {${getName()}}"; echo "This is the value of the var named by the return value of \$object->getName(): {${$object->getName()}}"; // Won't work, outputs: This is the return value of getName(): {getName()} echo "This is the return value of getName(): {getName()}"; ?>
Often, this syntax is unnecessary. For example, this:
$a = 'abcd';
$out = "$a $a"; // "abcd abcd";
behaves exactly the same as this:
$out = "{$a} {$a}"; // same
So the curly braces are unnecessary. But this:
$out = "$aefgh";
will, depending on your error level, either not work or produce an error because there's no variable named $aefgh
, so you need to do:
$out = "${a}efgh"; // or
$out = "{$a}efgh";
this may work for you :
document.addEventListener('DOMContentLoaded', function() {
// your code here
}, false);
or if your comfort with jquery,
$(document).ready(function(){
// your code
});
$(document).ready()
fires on DOMContentLoaded, but this event is not being fired consistently among browsers. This is why jQuery will most probably implement some heavy workarounds to support all the browsers. And this will make it very difficult to "exactly" simulate the behavior using plain Javascript (but not impossible of course).
as Jeffrey Sweeney and J Torres suggested, i think its better to have a setTimeout
function, before firing the function like below :
setTimeout(function(){
//your code here
}, 3000);
1.CURSOR: When PLSQL issues sql statements it creates private work area to parse & execute the sql statement is called cursor.
2.IMPLICIT: When any PL/SQLexecutable block issues sql statement. PL/SQL creates implicit cursor and manages automatically means implcit open & close takes place. It used when sql statement return only one row.It has 4 attributes SQL%ROWCOUNT, SQL%FOUND, SQL%NOTFOUND, SQL%ISOPEN.
3.EXPLICIT: It is created & managed by the programmer. It needs every time explicit open,fetch & close. It is used when sql statement returns more than one row. It has also 4 attributes CUR_NAME%ROWCOUNT, CUR_NAME%FOUND, CUR_NAME%NOTFOUND, CUR_NAME%ISOPEN. It process several rows by using loop. The programmer can pass the parameter too to explicit cursor.
declare
cursor emp_cursor
is
select id,name,salary,dept_id
from employees;
v_id employees.id%type;
v_name employees.name%type;
v_salary employees.salary%type;
v_dept_id employees.dept_id%type;
begin
open emp_cursor;
loop
fetch emp_cursor into v_id,v_name,v_salary,v_dept_id;
exit when emp_cursor%notfound;
dbms_output.put_line(v_id||', '||v_name||', '||v_salary||','||v_dept_id);
end loop;
close emp_cursor;
end;
There are several methods of std::string for searching, but find is probably what you're looking for. If you mean a C-style string, then the equivalent is strchr. However, in either case, you can also use a for loop and check each character—the loop is essentially what these two wrap up.
Once you know how to find the next character given a starting position, you continually advance your search (i.e. use a loop), counting as you go.
While working in a big project which has complex build system and where it is hard to get (or modify) the gcc/g++ command directly there is another way to see the result of macro expansion. Simply redefine the macro, and you will get output similiar to following:
file.h: note: this is the location of the previous definition
#define MACRO current_value
New-style classes inherit from object
, or from another new style class:
class SomeObject(object):
pass
class SubObject(SomeObject):
pass
Old-style classes don't:
class SomeObject:
pass
This only applies to Python 2 - in Python 3 all the above will create new-style classes.
See 9. Classes (Python tutorial), NewClassVsClassicClass and What is the difference between old style and new style classes in Python? for details.
While I was creating a reactive form, I had to assign 2 types of class on the button. This is how I did it:
<button type="submit" class="btn" [ngClass]="(formGroup.valid)?'btn-info':''"
[disabled]="!formGroup.valid">Sign in</button>
When the form is valid, button has btn and btn-class (from bootstrap), otherwise just btn class.

My answer is quite easy:
Use Entity Framework for communication between C# and your SQL database. That will make parameterized SQL strings that isn't vulnerable to SQL injection.
As a bonus, it's very easy to work with as well.

In distributable software, I dont want my customers mucking about in the database by themselves. The program reads and writes it all by itself. The only reason for a user to touch the DB file is to take a backup copy. Therefore I have named it whatever_records.db
The simple .db extension tells the user that it is a binary data file and that's all they have to know. Calling it .sqlite invites the interested user to open it up and mess something up!
Totally depends on your usage scenario I suppose.
With curl
and jq
:
curl -s <jenkins_url>/pluginManager/api/json?depth=1 \
| jq -r '.plugins[] | "\(.shortName):\(.version)"' \
| sort
This command gives output in a format used by special Jenkins plugins.txt
file which enables you to pre-install dependencies (e.g. in a docker image):
ace-editor:1.1
ant:1.8
apache-httpcomponents-client-4-api:4.5.5-3.0
Example of a plugins.txt
: https://github.com/hoto/jenkinsfile-examples/blob/master/source/jenkins/usr/share/jenkins/plugins.txt

@Override
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.custom_actionbar, menu);
menu.setGroupVisible(...);

Excel only shows 255 characters but in fact if more than 255 characters are saved, to see the complete string, consult it in the immediate window
Press Crl + G and type ?RunWhat
in the immediate window and press Enter
<input type="text" required="true" value="" readonly="true">
This will make a text box in readonly mode, might be helpful in generating passwords and datepickers.
//Note for Linq Users/Coders
This should give you the exact comparison for checking if a date falls within range when working with input from a user - date picker for example:
((DateTime)ri.RequestX.DateSatisfied).Date >= startdate.Date &&
((DateTime)ri.RequestX.DateSatisfied).Date <= enddate.Date
where startdate and enddate are values from a date picker.
Use an ArrayList or juggle to arrays to auto increment the array size.
One of the ways that you can run your spring-boot application from command line is as follows :
1) First go to your project directory in command line [where is your project located ?]
2) Then in the next step you have to create jar file for that, this can be done as
mvnw package
[for WINDOWS OS ] or ./mvnw package
[for MAC OS] , this will
create jar file for our application.
3) jar file is created in the target sub-directory
4)Now go to target sub directory as jar was created inside of it , i.e cd target
5) Now run the jar file in there.
Use command java -jar name.jar
[ name is the name of your created jar file.]
and there you go , you are done . Now you can run project in browser,
http://localhost:port_number
You can use also
select * from tablename where column1 ='a' and column2!='b';
My suggestion for google maps api v3 would be(don't think it can be done more effeciently):
gmap : {
fitBounds: function(bounds, mapId)
{
//incoming: bounds - bounds object/array; mapid - map id if it was initialized in global variable before "var maps = [];"
if (bounds==null) return false;
maps[mapId].fitBounds(bounds);
}
}
In the result u will fit all points in bounds in your map window.
Example works perfectly and u freely can check it here www.zemelapis.lt
I believe java gleans this from the environment variables in which it was launched, so you'll need to make sure your LANG and LC_* environment variables are set appropriately.
The locale manpage has full info on said environment variables.
in widget use 'value' attr. Example:
username = forms.CharField(
required=False,
widget=forms.TextInput(attrs={'readonly': True, 'value': 'CONSTANT_VALUE'}),
)
All you need to give the name attribute to the each button. And you need to address each button press from the PHP script. But be careful to give each button a unique name. Because the PHP script only take care of the name most of the time
<input type="submit" name="Submit_this" id="This" />
No need to type in the password, just use any one of these commands (self explanatory):
mysqlcheck --all-databases -a #analyze
mysqlcheck --all-databases -r #repair
mysqlcheck --all-databases -o #optimize
For ICS I´ve implemented your code and made a class that extends AsyncTask
. I hope you appreciate it! Thanks for your code and solution.
public class UpdateApp extends AsyncTask<String,Void,Void>{
private Context context;
public void setContext(Context contextf){
context = contextf;
}
@Override
protected Void doInBackground(String... arg0) {
try {
URL url = new URL(arg0[0]);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = "/mnt/sdcard/Download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "update.apk");
if(outputFile.exists()){
outputFile.delete();
}
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
context.startActivity(intent);
} catch (Exception e) {
Log.e("UpdateAPP", "Update error! " + e.getMessage());
}
return null;
}
}
To use it, in your main activity call by this way:
atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");
Summarizing the Answers
I can see many different answers and ways to do this but there is the rub in this and that is the objective
.
Yes, the objective. If you want to only know
the column names you can use
SELECT * FROM my_table WHERE 1=0
or
SELECT TOP 0 * FROM my_table
But if you want to use
those columns somewhere or simply say manipulate
them then the quick queries above are not going to be of any use. You need to use
SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = N'Customers'
one more way to know some specific columns where we are in need of some similar columns
SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME like N'%[ColumnName]%' and TABLE_NAME = N'[TableName]'
You can also change the position of the body/html to fixed:
body,
html {
position: fixed;
}
