I was running Vagrant with VirtualBox 5.1.X, and had to downgrade to VirtualBox 5.0.40, and install the vbguest plugin to solve this problem.
vagrant up
for my vagrant. It'll fail.vagrant plugin install vagrant-vbguest
while my VM is running, to install the vagrant plugin. This manages syncing VirtualBox Guest versions between host and guest.vagrant reload
to reload my virtual machineI had the same problem, and
neither umount /path -f
,
neither umount.nfs /path -f
,
neither fuser -km /path
,
works
finally I found a simple solution >.<
sudo /etc/init.d/nfs-common restart
, then lets do the simple umount
;-)
Please try the below this is the easiest way and it works perfectly
var newSkill_Text = document.getElementById("newSkill")[document.getElementById("newSkill").selectedIndex];
Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.
My setup was as follows:
I put the following formula in cell A1 of Sheet3:
=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)
Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.
Notes:
In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.
A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.
After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)
and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.
Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.
Cells A2, A3, etc. will get these formulas:
=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)
Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.
The standard option grep -l
(that is a lowercase L) could do this.
From the Unix standard:
-l
(The letter ell.) Write only the names of files containing selected
lines to standard output. Pathnames are written once per file searched.
If the standard input is searched, a pathname of (standard input) will
be written, in the POSIX locale. In other locales, standard input may be
replaced by something more appropriate in those locales.
You also do not need -H
in this case.
If I understand correctly. In order to group your results as requested, your Group By clause needs to have the same expression as your select statement.
GROUP BY MONTH(date) + '.' + YEAR(date)
To display the date as "month-date" format change the '.' to '-' The full syntax would be something like this.
SELECT MONTH(date) + '-' + YEAR(date) AS Mjesec, SUM(marketingExpense) AS
SumaMarketing, SUM(revenue) AS SumaZarada
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY MONTH(date) + '.' + YEAR(date)

}
} catch (ClientProtocolException e) {

@Override
public void customizeWebView(final ServiceCommunicableActivity activity, final WebView webview, final SearchResult mRom) {
mRom.setFileSize(getFileSize(mRom.getURLSuffix()));
webview.getSettings().setJavaScriptEnabled(true);
WebViewClient anchorWebViewClient = new WebViewClient()
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
//Do what you want to with the html
String html = getHTML(url);
if( html!=null && !url.equals(lastLoadedURL)){
lastLoadedURL = url;
webview.loadDataWithBaseURL(url, html, null, "utf-8", url);
}
}
This should roughly do what you want to do. It is adapted from Is it possible to get the HTML code from WebView and shout out to https://stackoverflow.com/users/325081/aymon-fournier for his answer.

command is what you looking for.
If you looking ONLY the case when enter is hit you can abuse the runas
command:
runas /user:# "" >nul 2>&1
the screen will be frozen until enter is hit.What I like more than set/p=
is that if you press other buttons than enter they will be not displayed.
A class is basically a definition, and contains the object's code. An object is an instance of a class
for example if you say
String word = new String();
the class is the String class, which describes the object (instance) word.
When a class is declared, no memory is allocated so class is just a template.
When the object of the class is declared, memory is allocated.
How was your 2D array declared?
If it something like:
int arr[20][30];
You can zero it by doing:
memset(arr, sizeof(int)*20*30);
You should not use jQuery in Angular. While it is possible (see other answers for this question), it is discouraged. Why?
Angular holds an own representation of the DOM in its memory and doesn't use query-selectors (functions like document.getElementById(id)
) like jQuery. Instead all the DOM-manipulation is done by Renderer2 (and Angular-directives like *ngFor and *ngIf accessing that Renderer2 in the background/framework-code). If you manipulate DOM with jQuery yourself you will sooner or later...
If you really want to include jQuery (for duck-taping some prototype that you will 100% definitively throw away), I recommend to at least include it in your package.json with npm install --save jquery
instead of getting it from google's CDN.
TLDR: For learning how to manipulate the DOM in the Angular way please go through the official tour-of heroes tutorial first: https://angular.io/tutorial/toh-pt2 If you need to access elements higher up in the DOM hierarchy (parent or
document body
) or for some other reason directives like*ngIf
,*ngFor
, custom directives, pipes and other angular utilities like[style.background]
,[class.myOwnCustomClass]
don't satisfy your needs, use Renderer2: https://www.concretepage.com/angular-2/angular-4-renderer2-example
I got the same error message on GraphQL mutation input object then I found the problem, Actually in my case mutation expecting an object array as input but I'm trying to insert a single object as input. For example:
First try
const mutationName = await apolloClient.mutate<insert_mutation, insert_mutationVariables>({
mutation: MUTATION,
variables: {
objects: {id: 1, name: "John Doe"},
},
});
Corrected mutation call as an array
const mutationName = await apolloClient.mutate<insert_mutation, insert_mutationVariables>({
mutation: MUTATION,
variables: {
objects: [{id: 1, name: "John Doe"}],
},
});
Sometimes simple mistakes like this can cause the problems. Hope this'll help someone.
You should use profiles.
<profiles>
<profile>
<id>otherOutputDir</id>
<build>
<directory>yourDirectory</directory>
</build>
</profile>
</profiles>
And start maven with your profile
mvn compile -PotherOutputDir
If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :
<properties>
<buildDirectory>${project.basedir}/target</buildDirectory>
</properties>
<build>
<directory>${buildDirectory}</directory>
</build>
And compile like this :
mvn compile -DbuildDirectory=test
That's because you can't change the target directory by using -Dproject.build.directory
It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.
Edit: This is what the forums say:
By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.
To disable:
/system/bin/bugmailer.sh must be deleted/renamed.
There should be a folder on your SD card called "bug reports".

Make

That is, double brackets and no quotes.
The right side of ==

If you need a regular expression, use =~
then.
Open the php.ini

I wrote a simple test for all the above.

puts "#{[a, '.equal?', b]} : #{a.equal?(b)}"

for y in range(2,int(x**0.5)+1) :

isPrime=False
break
if isPrime:
primeList.append(x)
print(primeList)
For tables and columns:
show create table your_table_name
It's perfectly possible to template a class on an integer rather than a type. We can assign the templated value to a variable, or otherwise manipulate it in a way we might with any other integer literal:
unsigned int x = N;
In fact, we can create algorithms which evaluate at compile time (from Wikipedia):
template <int N>
struct Factorial
{
enum { value = N * Factorial<N - 1>::value };
};
template <>
struct Factorial<0>
{
enum { value = 1 };
};
// Factorial<4>::value == 24
// Factorial<0>::value == 1
void foo()
{
int x = Factorial<4>::value; // == 24
int y = Factorial<0>::value; // == 1
}
Well, all answersabove are good but not in all cases.
Basically check the folder /etc/postgresql/
in most cases there will be one subfolder eg. /etc/postgresql/11/
(or /etc/postgresql/12
) which means that you have installed 11 (or 12) version, however in many cases you may have many of such subfolders, so having them all means that all those versions had been ever installed and could be in use ... so be aware of this important trace.
ps using Ubuntu 18.04
Are you sure you correctly applied the styles, or that there isn't another stylesheet interfering with your lists? I tried this:
<ol type="A">
<li><span class="label">Text</span></li>
<li><span class="label">Text</span></li>
<li><span class="label">Text</span></li>
</ol>
Then in the stylesheet:
ol {font-weight: bold;}
ol li span.label {font-weight:normal;}
And it bolded the A
, B
, C
etc and not the text.
(Tested it in Opera 9.6, FF 3, Safari 3.2 and IE 7)
As already written in answers you need to drop constraints (created automatically by sql) related to all columns that you are trying to delete.
Perform followings steps to do the needful.
exec sp_helpconstraint '<your table name>'
alter table <your_table_name>
drop constraint <constraint_name_that_you_copied_in_1>
(It'll be something like this only or similar format)Alter table <YourTableName> Drop column column1, column2
etcYou have to use bracket notation:
var obj = {};
obj[a[i]] = 0;
x.push(obj);
The result will be:
x = [{left: 0}, {top: 0}];
Maybe instead of an array of objects, you just want one object with two properties:
var x = {};
and
x[a[i]] = 0;
This will result in x = {left: 0, top: 0}
.
You cannot use a variable in a create table statement. The best thing I can suggest is to write the entire query as a string and exec that.
Try something like this:
declare @query varchar(max);
set @query = 'create database TEST...';
exec (@query);
int is a primitive type, you can read what does mean a primitive type in java here, and a Map is an interface that has to objects as input:
public interface Map<K extends Object, V extends Object>
object means a class, and it means also that you can create an other class that exends from it, but you can not create a class that exends from int. So you can not use int variable as an object. I have tow solutions for your problem:
Map<String, Integer> map = new HashMap<>();
or
Map<String, int[]> map = new HashMap<>();
int x = 1;
//put x in map
int[] x_ = new int[]{x};
map.put("x", x_);
//get the value of x
int y = map.get("x")[0];
In the shell, you can't execute more than one statement at a time:
>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement
You need to execute them one by one:
>>> x = 5
>>> y = 6
>>>
When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.
Try to use:
mvn clean package install
This command should install your artifacts in you local maven repo.
PS: I see that this is an old question, but it may be helpful for somebody in the future.
That's because there are no spaces in that long string so it has to break out of its container. Add word-break:break-all;
to your .title rules to force a break.

font-size:12px;
word-break:break-all;

frame.getContentPane().add(lblimage, BorderLayout.CENTER);
frame.setSize(image.getWidth(null) + 50, image.getHeight(null) + 50);

In order to reference a user ID created using simple authentication built into ASP.NET MVC 4 in a controller for filtering purposes (which is helpful if you are using database first and Entity Framework 5 to generate code-first bindings and your tables are structured so that a foreign key to the userID is used), you can use

You can use node-uuid (https://github.com/kelektiv/node-uuid)
Simple, fast generation of RFC4122 UUIDS.
Features:
Install Using NPM:
npm install uuid
Or Using uuid via browser:
Download Raw File (uuid v1): https://raw.githubusercontent.com/kelektiv/node-uuid/master/v1.js Download Raw File (uuid v4): https://raw.githubusercontent.com/kelektiv/node-uuid/master/v4.js
Want even smaller? Check this out: https://gist.github.com/jed/982883
Usage:
// Generate a v1 UUID (time-based)
const uuidV1 = require('uuid/v1');
uuidV1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
// Generate a v4 UUID (random)
const uuidV4 = require('uuid/v4');
uuidV4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'
// Generate a v5 UUID (namespace)
const uuidV5 = require('uuid/v5');
// ... using predefined DNS namespace (for domain names)
uuidV5('hello.example.com', v5.DNS)); // -> 'fdda765f-fc57-5604-a269-52a7df8164ec'
// ... using predefined URL namespace (for, well, URLs)
uuidV5('http://example.com/hello', v5.URL); // -> '3bbcee75-cecc-5b56-8031-b6641c1ed1f1'
// ... using a custom namespace
const MY_NAMESPACE = '(previously generated unique uuid string)';
uuidV5('hello', MY_NAMESPACE); // -> '90123e1c-7512-523e-bb28-76fab9f2f73d'
ES6:
import uuid from 'uuid/v4';
const id = uuid();

It's worth adding here as it is such a highly ranking question on zip. zip
is great, idiomatic Python - but it doesn't scale very well at all for large lists.
Instead of:
books = ['AAAAAAA', 'BAAAAAAA', ... , 'ZZZZZZZ']
words = [345, 567, ... , 672]
for book, word in zip(books, words):
print('{}: {}'.format(book, word))
Use izip
. For modern processing, it stores it in L1 Cache memory and is far more performant for larger lists. Use it as simply as adding an i
:
for book, word in izip(books, words):
print('{}: {}'.format(book, word))
what I'm doing wrong here?
Almost everything.
$today = date('Y-m-d'); // no need for strtotime
$sth = $db->prepare("SELECT id_email FROM db WHERE hardcopy = '1' AND hardcopy_date <= :today AND hardcopy_sent = '0' ORDER BY id_email ASC");
$sth->bindParam(':today',$today); // no need for PDO::PARAM_STR
$sth->execute(); // no need for if
$this->id_email = $sth->fetchAll(PDO::FETCH_COLUMN); // no need for while
return count($this->id_email); // no need for the everything else
effectively, you always have your fetched data (in this case in $this->id_email
variable) to tell whether your query returned anything or not. Read more in my article on PDO.

Specifying the height of the video will change the quality accordingly. example for html 5;
<iframe style='width:100%; height:800px;' src='https://www.youtube.com/embed/xxxxxxxx'></iframe>
If you don't want to hardcode the width and height you can add a class to the iframe for css media queries.

If there are no spaces in paths, and you are interested, like I was, in files of specific extension only, you can use

The use of "closed" vs. "open" reflects whether or not we are locked in to using a certain position or data structure (this is an extremely vague description, but hopefully the rest helps).
For instance, the "open" in "open addressing" tells us the index (aka. address) at which an object will be stored in the hash table is not completely determined by its hash code. Instead, the index may vary depending on what's already in the hash table.
The "closed" in "closed hashing" refers to the fact that we never leave the hash table; every object is stored directly at an index in the hash table's internal array. Note that this is only possible by using some sort of open addressing strategy. This explains why "closed hashing" and "open addressing" are synonyms.
Contrast this with open hashing - in this strategy, none of the objects are actually stored in the hash table's array; instead once an object is hashed, it is stored in a list which is separate from the hash table's internal array. "open" refers to the freedom we get by leaving the hash table, and using a separate list. By the way, "separate list" hints at why open hashing is also known as "separate chaining".
In short, "closed" always refers to some sort of strict guarantee, like when we guarantee that objects are always stored directly within the hash table (closed hashing). Then, the opposite of "closed" is "open", so if you don't have such guarantees, the strategy is considered "open".
As the statement executed is not actually DML (eg UPDATE
, INSERT
or EXECUTE
), but a piece of T-SQL which contains DML, I suspect it is not treated as an update-query.
Section 13.1.2.3 of the JDBC 4.1 specification states something (rather hard to interpret btw):
When the method
execute
returns true, the methodgetResultSet
is called to retrieve the ResultSet object. Whenexecute
returns false, the methodgetUpdateCount
returns an int. If this number is greater than or equal to zero, it indicates the update count returned by the statement. If it is -1, it indicates that there are no more results.
Given this information, I guess that executeUpdate()
internally does an execute()
, and then - as execute()
will return false
- it will return the value of getUpdateCount()
, which in this case - in accordance with the JDBC spec - will return -1
.
This is further corroborated by the fact 1) that the Javadoc for Statement.executeUpdate()
says:
Returns: either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing
And 2) that the Javadoc for Statement.getUpdateCount() specifies:
the current result as an update count; -1 if the current result is a ResultSet object or there are no more results
Just to clarify: given the Javadoc for executeUpdate()
the behavior is probably wrong, but it can be explained.
Also as I commented elsewhere, the -1 might just indicate: maybe something was changed, but we simply don't know, or we can't give an accurate number of changes (eg because in this example it is a piece of T-SQL that is executed).
this works with 0 arguments with gcc/llvm. [links are dumb]
/*

* the arguments are pushed out in such a way that 'cnt' ends up with

switch(0) {\

C_ASSERT(0 == COUNT_ARGS());
C_ASSERT(1 == COUNT_ARGS(a));
C_ASSERT(2 == COUNT_ARGS(a,b));
C_ASSERT(3 == COUNT_ARGS(a,b,c));
C_ASSERT(4 == COUNT_ARGS(a,b,c,d));
C_ASSERT(5 == COUNT_ARGS(a,b,c,d,e));
C_ASSERT(6 == COUNT_ARGS(a,b,c,d,e,f));
return 0;
}
Visual Studio seems to be ignoring the ## operator used to consume the empty argument. You can probably get around that with something like
#define CNT_ COUNT_ARGS
#define PASTE(x,y) PASTE_(x,y)
#define PASTE_(x,y) x ## y
#define CNT(...) PASTE(ARGVS,PASTE(CNT_(__VA_ARGS__),CNT_(1,##__VA_ARGS__)))
//you know its 0 if its 11 or 01
#define ARGVS11 0
#define ARGVS01 0
#define ARGVS12 1
#define ARGVS23 2
#define ARGVS34 3

As you may have already figured, Asp.Net MVC is a different paradigm than Asp.Net (webforms). Accessing form elements between the server and client take a different approach in Asp.Net MVC.
You can google more reading material on this on the web. For now, I would suggest using Ajax to get or post data to the server. You can still employ input type="hidden"
, but initialize it with a value from the ViewData
or for Razor, ViewBag
.
For example, your controller may look like this:
public ActionResult Index()
{
ViewBag.MyInitialValue = true;
return View();
}
In your view, you can have an input elemet that is initialized by the value in your ViewBag
:
<input type="hidden" name="myHiddenInput" id="myHiddenInput" value="@ViewBag.MyInitialValue" />
Then you can pass data between the client and server via ajax. For example, using jQuery:
$.get('GetMyNewValue?oldValue=' + $('#myHiddenInput').val(), function (e) {
// blah
});
You can alternatively use $.ajax
, $.getJSON
, $.post
depending on your requirement.
This might be optimal
public static string GetPropertyName<TResult>(Expression<Func<TResult>> expr)
{
var memberAccess = expr.Body as MemberExpression;
var propertyInfo = memberAccess?.Member as PropertyInfo;
var propertyName = propertyInfo?.Name;
return propertyName;
}
You can use an object as a map:
var hasName = ({
"true" : "Y",
"false" : "N"
})[name];
This also scales nicely for many options
var hasName = ({
"true" : "Y",
"false" : "N",
"fileNotFound" : "O"
})[name];
(Bonus point for people getting the reference)
Note: you should use actual booleans instead of the string value "true" for your variables indicating truth values.
PHP's strtotime
function will interpret timezone codes, like UTC. If you get the date from the database/client without the timezone code, but know it's UTC, then you can append it.
Assuming you get the date with timestamp code (like "Fri Mar 23 2012 22:23:03 GMT-0700 (PDT)", which is what Javascript code ""+(new Date())
gives):
$time = strtotime($dateWithTimeZone);
$dateInLocal = date("Y-m-d H:i:s", $time);
Or if you don't, which is likely from MySQL, then:
$time = strtotime($dateInUTC.' UTC');
$dateInLocal = date("Y-m-d H:i:s", $time);

Your command line mvn eclipse project generator may not be the same version as that of your eclipse, and eclipse doesn't understand for your command line tool is generating. Just use eclipse's in this case:
rm -rf .settings/ .project .classpath
to delete eclipse project files, also from modules Gabriel Lame's Theorem bounds the number of steps by log(1/sqrt(5)*(a+1/2))-2, where the base of the log is (1+sqrt(5))/2. This is for the the worst case scenerio for the algorithm and it occurs when the inputs are consecutive Fibanocci numbers.
A slightly more liberal bound is: log a, where the base of the log is (sqrt(2)) is implied by Koblitz.
For cryptographic purposes we usually consider the bitwise complexity of the algorithms, taking into account that the bit size is given approximately by k=loga.
Here is a detailed analysis of the bitwise complexity of Euclid Algorith:
Although in most references the bitwise complexity of Euclid Algorithm is given by O(loga)^3 there exists a tighter bound which is O(loga)^2.
Consider; r0=a, r1=b, r0=q1.r1+r2 . . . ,ri-1=qi.ri+ri+1, . . . ,rm-2=qm-1.rm-1+rm rm-1=qm.rm
observe that: a=r0>=b=r1>r2>r3...>rm-1>rm>0 ..........(1)
and rm is the greatest common divisor of a and b.
By a Claim in Koblitz's book( A course in number Theory and Cryptography) is can be proven that: ri+1<(ri-1)/2 .................(2)
Again in Koblitz the number of bit operations required to divide a k-bit positive integer by an l-bit positive integer (assuming k>=l) is given as: (k-l+1).l ...................(3)
By (1) and (2) the number of divisons is O(loga) and so by (3) the total complexity is O(loga)^3.
Now this may be reduced to O(loga)^2 by a remark in Koblitz.
consider ki= logri +1
by (1) and (2) we have: ki+1<=ki for i=0,1,...,m-2,m-1 and ki+2<=(ki)-1 for i=0,1,...,m-2
and by (3) the total cost of the m divisons is bounded by: SUM [(ki-1)-((ki)-1))]*ki for i=0,1,2,..,m
rearranging this: SUM [(ki-1)-((ki)-1))]*ki<=4*k0^2
So the bitwise complexity of Euclid's Algorithm is O(loga)^2.
You can also use scopes like this below and put them in a concern and include in models you may need them:
scope :ci_find, lambda { |column, value| where("lower(#{column}) = ?", value.downcase).first }
Then use like this:
Model.ci_find('column', 'value')
Try this
@echo off
setlocal enableextensions enabledelayedexpansion
set firstLine=1
for /f "delims=" %%i in (yourfilename.txt) do (
if !firstLine!==1 echo %%i
set firstLine=0
)
endlocal
"What is it?" and "What does it do?" has been explained above.
I will give a example of "when it should be used".
For example, we have a class with lots of resource like big array in it.
class ResHeavy{ // ResHeavy means heavy resource
public:
ResHeavy(int len=10):_upInt(new int[len]),_len(len){
cout<<"default ctor"<<endl;
}
ResHeavy(const ResHeavy& rhs):_upInt(new int[rhs._len]),_len(rhs._len){
cout<<"copy ctor"<<endl;
}
ResHeavy& operator=(const ResHeavy& rhs){
_upInt.reset(new int[rhs._len]);
_len = rhs._len;
cout<<"operator= ctor"<<endl;
}
ResHeavy(ResHeavy&& rhs){
_upInt = std::move(rhs._upInt);
_len = rhs._len;
rhs._len = 0;
cout<<"move ctor"<<endl;
}
// check array valid
bool is_up_valid(){
return _upInt != nullptr;
}
private:
std::unique_ptr<int[]> _upInt; // heavy array resource
int _len; // length of int array
};
Test code:
void test_std_move2(){
ResHeavy rh; // only one int[]
// operator rh
// after some operator of rh, it becomes no-use
// transform it to other object
ResHeavy rh2 = std::move(rh); // rh becomes invalid
// show rh, rh2 it valid
if(rh.is_up_valid())
cout<<"rh valid"<<endl;
else
cout<<"rh invalid"<<endl;
if(rh2.is_up_valid())
cout<<"rh2 valid"<<endl;
else
cout<<"rh2 invalid"<<endl;
// new ResHeavy object, created by copy ctor
ResHeavy rh3(rh2); // two copy of int[]
if(rh3.is_up_valid())
cout<<"rh3 valid"<<endl;
else
cout<<"rh3 invalid"<<endl;
}
output as below:
default ctor
move ctor
rh invalid
rh2 valid
copy ctor
rh3 valid
We can see that std::move
with move constructor
makes transform resource easily.
Where else is std::move
useful?
std::move
can also be useful when sorting an array of elements. Many sorting algorithms (such as selection sort and bubble sort) work by swapping pairs of elements. Previously, we’ve had to resort to copy-semantics to do the swapping. Now we can use move semantics, which is more efficient.
It can also be useful if we want to move the contents managed by one smart pointer to another.

I posted my flexbox approach here:
One idea I rejected was to remove the padding from the outer columns with something like this:
div:nth-child(#{$col-number}n+1) { padding-left: 0; }
div:nth-child(#{$col-number}n+#{$col-number}) { padding-left: 0; }
But, like other posters here, I prefer the negative margin trick. My fiddle also has responsiveness for anyone is looking for a Sass-based solution. I basically use this approach in place of a grid.
just a moment ago, i came across with the same issue. and i resolve it in the following manner.
Response.Redirect("../index.aspx?Name="+this.textName.Text+"&LastName="+this.textlName.Text);
with reference to the this
Let us consider table name as tblperson
and column name as city
. I want to retrieve the most repeated city from the city column:
select city,count(*) as nor from tblperson
group by city

Here nor
is an alias name.
You could get the full path as a string then split it into a list using your operating system's separator character. Then you get the program name, folder name etc by accessing the elements from the end of the list using negative indices.
Like this:
import os
strPath = os.path.realpath(__file__)
print( f"Full Path :{strPath}" )
nmFolders = strPath.split( os.path.sep )
print( "List of Folders:", nmFolders )
print( f"Program Name :{nmFolders[-1]}" )
print( f"Folder Name :{nmFolders[-2]}" )
print( f"Folder Parent:{nmFolders[-3]}" )
The output of the above was this:
Full Path :C:\Users\terry\Documents\apps\environments\dev\app_02\app_02.py
List of Folders: ['C:', 'Users', 'terry', 'Documents', 'apps', 'environments', 'dev', 'app_02', 'app_02.py']
Program Name :app_02.py
Folder Name :app_02
Folder Parent:dev

//without servlet
((HttpSession) ctx.getSession(false)).invalidate();
//redirect with JSF context.
ctx.redirect(ctxPath + "absolute/path/index.jsp");
} catch (IOException ex) {
System.out.println(ex.getMessage());
}

hope this may help you:

You can use outline with outline offset
<div class="double-border"></div>
.double-border{
background-color:#ccc;
outline: 1px solid #f00;
outline-offset: 3px;
}
Addendum to @sjngm's answer:
They both also ignore whitespace:
var foo = " 3 "; console.log(parseInt(foo)); // 3 console.log(Number(foo)); // 3
It is not exactly correct. As sjngm wrote parseInt parses string to first number. It is true. But the problem is when you want to parse number separated with whitespace ie. "12 345". In that case parseInt("12 345")
will return 12
instead of 12345
.
So to avoid that situation you must trim whitespaces before parsing to number.
My solution would be:
var number=parseInt("12 345".replace(/\s+/g, ''),10);
Notice one extra thing I used in parseInt() function. parseInt("string",10)
will set the number to decimal format. If you would parse string like "08" you would get 0 because 8 is not a octal number.Explanation is here
Improve RouMao's solution by temporarily disabling GIT/curl ssl verification in Windows cmd:
set GIT_SSL_NO_VERIFY=true

For me the problem happens if I simply create an empty matplotlibrc
file under ~/.matplotlib
on macOS. Adding "backend: macosx" in it fixes the problem.
I think it is a bug: if backend

it should take the default value.

As a hack, you could consider having a special handling on the client side, converting 'Null' string to something that will never occur, for example, XXNULLXX and converting back on the server.
It is not pretty, but it may solve the issue for such a boundary case.
function solve(n){
let DP = [];
DP[0] = DP[1] = DP[2] = 1;
DP[3] = 2;
for (let i = 4; i <= n; i++) {
DP[i] = DP[i-1] + DP[i-3] + DP[i-4];
}
return DP[n]
}

This is a Dynamic Solution for JS to tell how many ways anyone can get the certain sum. This can be the right solution if you think about time and space complexity.
While you can do
value = d.values()[index]
It should be faster to do
value = next( v for i, v in enumerate(d.itervalues()) if i == index )
edit: I just timed it using a dict of len 100,000,000 checking for the index at the very end, and the 1st/values() version took 169 seconds whereas the 2nd/next() version took 32 seconds.
Also, note that this assumes that your index is not negative
late to the party. but if you only want to get rid of leading/trailing white space, R base has a function trimws
For example:
data <- apply(X = data, MARGIN = 2, FUN = trimws) %>% as.data.frame()
Some of the comments mention this as well, but asp net core does all this work for you.
If you have a query string that matches the name it will be available in the controller.

You need to dynamically allocate your matrix. For instance:
int* mat;
int dimx,dimy;
scanf("%d", &dimx);
scanf("%d", &dimy);
mat = malloc(dimx * dimy * sizeof(int));
This creates a linear array which can hold the matrix. At this point you can decide whether you want to access it column or row first. I would suggest making a quick macro which calculates the correct offset in the matrix.
Using file extension and getimagesize
function to detect if uploaded file has right format is just the entry level check and it can simply bypass by uploading a file with true extension and some byte of an image header but wrong content.
for being secure and safe you may make thumbnail/resize (even with original image sizes) the uploaded picture and save this version instead the uploaded one.
Also its possible to get uploaded file content and search it for special character like <?php
to find the file is image or not.
Instead of using width
(which is a suggestion when using flexbox), you could use flex: 0 0 230px;
which means:
0
= don't grow (shorthand for flex-grow
)0
= don't shrink (shorthand for flex-shrink
)230px
= start at 230px
(shorthand for flex-basis
)which means: always be 230px

Just set setStackFromEnd=true
or setReverseLayout=true
so that LLM will layout items from end.
The difference between these two is that setStackFromEnd
will set the view to show the last element, the layout direction will remain the same. (So, in an left-to-right horizontal Recycler View, the last element will be shown and scrolling to the left will show the earlier elements)
Whereas setReverseLayout
will change the order of the elements added by the Adapter. The layout will start from the last element, which will be the left-most in an LTR Recycler View and then, scrolling to the right will show the earlier elements.
Sample:
final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
linearLayoutManager.setReverseLayout(true);
_listView.setLayoutManager(linearLayoutManager);

See part 6. HTTP Authentication
HTTP Authentication
HTTP Authentication is the ability to tell the server your username and password so that it can verify that you're allowed to do the request you're doing. The Basic authentication used in HTTP (which is the type curl uses by default) is plain text based, which means it sends username and password only slightly obfuscated, but still fully readable by anyone that sniffs on the network between you and the remote server.
To tell curl to use a user and password for authentication:
curl --user name:password http://www.example.com
The site might require a different authentication method (check the headers returned by the server), and then --ntlm, --digest, --negotiate or even --anyauth might be options that suit you.
Sometimes your HTTP access is only available through the use of a HTTP proxy. This seems to be especially common at various companies. A HTTP proxy may require its own user and password to allow the client to get through to the Internet. To specify those with curl, run something like:
curl --proxy-user proxyuser:proxypassword curl.haxx.se
If your proxy requires the authentication to be done using the NTLM method, use --proxy-ntlm, if it requires Digest use --proxy-digest.
If you use any one these user+password options but leave out the password part, curl will prompt for the password interactively.
Do note that when a program is run, its parameters might be possible to see when listing the running processes of the system. Thus, other users may be able to watch your passwords if you pass them as plain command line options. There are ways to circumvent this.
It is worth noting that while this is how HTTP Authentication works, very many web sites will not use this concept when they provide logins etc. See the Web Login chapter further below for more details on that.
A single line:
this.Location = new Point((Screen.PrimaryScreen.WorkingArea.Width - this.Width) / 2,
(Screen.PrimaryScreen.WorkingArea.Height - this.Height) / 2);
You can do that:
function formatAMPM(date) { // This is to display 12 hour format like you asked
var hours = date.getHours();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0'+minutes : minutes;
var strTime = hours + ':' + minutes + ' ' + ampm;
return strTime;
}
var myDate = new Date();
var displayDate = myDate.getMonth()+ '/' +myDate.getDate()+ '/' +myDate.getFullYear()+ ' ' +formatAMPM(myDate);
console.log(displayDate);
Paresh Mayani's answer is mostly correct. Simply use a Broadcast Intent to let the system and all the other apps choose in what way the content is going to be shared.
To share text use the following code:
String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));
This XML file does not appear to have any style information associated with it. The document tree is shown below.
You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml
instead of text/html
and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.
In case of JSF/Facelets files which have the default extension of .xhtml
, that can in turn happen if the HTTP request hasn't invoked the FacesServlet
and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml
file extension which is in your Firefox configuration apparently by default interpreted as text/xml
.
You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern>
of the FacesServlet
as registered in webapp's web.xml
, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf
, then you need to open the page by /some.jsf
instead of /some.xhtml
. Alternatively, you can also just change the <url-pattern>
to *.xhtml
. This way you never need to fiddle with virtual URLs.
Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.
Taking DWins example.
What I often do, particularly when I use many, many different plots with the same colours or size information, is I store them in variables I otherwise never use. This helps me keep my code a little cleaner AND I can change it "globally".
E.g.
clab = 1.5
cmain = 2
caxis = 1.2
plot(1, 1 ,xlab="x axis", ylab="y axis", pch=19,
col.lab="red", cex.lab=clab,
col="green", main = "Testing scatterplots", cex.main =cmain, cex.axis=caxis)
You can also write a function, doing something similar. But for a quick shot this is ideal. You can also store that kind of information in an extra script, so you don't have a messy plot script:
which you then call with setwd("") source("plotcolours.r")
in a file say called plotcolours.r you then store all the e.g. colour or size variables
clab = 1.5
cmain = 2
caxis = 1.2
for colours could use
darkred<-rgb(113,28,47,maxColorValue=255)
as your variable 'darkred' now has the colour information stored, you can access it in your actual plotting script.
plot(1,1,col=darkred)
Use the constructor that allows you to specify the year, month, day, hours, minutes, and seconds:
var dateNow = DateTime.Now;
var date = new DateTime(dateNow.Year, dateNow.Month, dateNow.Day, 4, 5, 6);
So this also happened to me too. I checked 50 times and my "Is Initial View Controller" was checked, believe me. It happened out of the blue. So how did I fix it?
You can do (jQuery 1.6 onwards):
$('#idCheckbox').prop('checked', true);
$('#idCheckbox').prop('checked', false);
to remove you can also use:
$('#idCheckbox').removeProp('checked');
with jQuery < 1.6 you must do
$('#idCheckbox').attr('checked', true);
$('#idCheckbox').removeAttr('checked');
I would do something like this:
$.each(temp,function(key, value)
{
$select.append('<option value=' + key + '>' + value + '</option>');
});
JSON structure would be appreciated. At first you can experiment with find('element')
- it depends on JSON.

delete _obj2;
std::cout << " _obj1: " << *_obj1->get() << std::endl;
delete _obj1;
std::cout << " done " << std::endl;
}
This is an example of shared_ptr in action. _obj2 was deleted but pointer is still valid. output is, ./test _obj1: 10 _obj2: 10 _obj2: 10 done
Because the dialog need a position, You need to include the js position
<script src="jquery.ui.position.js"></script>
There's a nice overview over some hash algorithms at Eternally Confuzzled. I'd recommend Bob Jenkins' one-at-a-time hash which quickly reaches avalanche and therefore can be used for efficient hash table lookup.
Considering that the accepted answer is probably inefficient for large arrays, O(nm), I usually prefer this approach, O(2n + 2m):
function mergeArrays(arr1 = [], arr2 = []){
//Creates an object map of id to object in arr1
const arr1Map = arr1.reduce((acc, o) => {
acc[o.id] = o;
return acc;
}, {});
//Updates the object with corresponding id in arr1Map from arr2,
//creates a new object if none exists (upsert)
arr2.forEach(o => {
arr1Map[o.id] = o;
});
//Return the merged values in arr1Map as an array
return Object.values(arr1Map);
}
Unit test:
it('Merges two arrays using id as the key', () => {
var arr1 = [{id:'124',name:'qqq'}, {id:'589',name:'www'}, {id:'45',name:'eee'}, {id:'567',name:'rrr'}];
var arr2 = [{id:'124',name:'ttt'}, {id:'45',name:'yyy'}];
const actual = mergeArrays(arr1, arr2);
const expected = [{id:'124',name:'ttt'}, {id:'589',name:'www'}, {id:'45',name:'yyy'}, {id:'567',name:'rrr'}];
expect(actual.sort((a, b) => (a.id < b.id)? -1: 1)).toEqual(expected.sort((a, b) => (a.id < b.id)? -1: 1));
})
Try This

return false;

I tried using all the above, nothing worked in my case.
I used the SumUp library which was causing this issue.
I fixed it by:
That still didn't fix the issue, I was still seeing errors all over the place hence coming to this thread,... however, after playing around with the settings the following fixed it:
I hope this helps for people using SumUP integration, it took the whole day to find out...

Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code
scGetruntotals.CommandTimeout = 180;
Note : the parameter value is in seconds.
This is how I did it.

There are some classes in the Java platform libraries that do extend an instantiable class and add a value component. For example, java.sql.Timestamp extends java.util.Date and adds a nanoseconds field. The equals implementation for Timestamp does violate symmetry and can cause erratic behavior if Timestamp and Date objects are used in the same collection or are otherwise intermixed. The Timestamp class has a disclaimer cautioning programmers against mixing dates and timestamps. While you won’t get into trouble as long as you keep them separate, there’s nothing to prevent you from mixing them, and the resulting errors can be hard to debug. This behavior of the Timestamp class was a mistake and should not be emulated.

An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view
. An index contains keys built from one or more columns in the table or view. These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently.
Indexes are automatically created when PRIMARY KEY and UNIQUE constraints are defined on table columns. For example, when you create a table with a UNIQUE constraint, Database Engine automatically creates a nonclustered index.
If you configure a PRIMARY KEY, Database Engine automatically creates a clustered index, unless a clustered index already exists. When you try to enforce a PRIMARY KEY constraint on an existing table and a clustered index already exists on that table, SQL Server enforces the primary key using a nonclustered index.
Please refer to this for more information about indexes (clustered and non clustered): https://docs.microsoft.com/en-us/sql/relational-databases/indexes/clustered-and-nonclustered-indexes-described?view=sql-server-ver15
Hope this helps!
Remove :
npm uninstall -g angular-cli
Reinstall (with yarn)
# npm install --global yarn
yarn global add @angular/cli@latest
ng set --global packageManager=yarn # This will help ng-cli to use yarn
Reinstall (with npm)
npm install --global @angular/cli@latest
Another way is to not use global install, and add /node_modules/.bin
folder in the PATH, or use npm scripts. It will be softer to upgrade.

I have a a blank solution BuildRebuildClean
and three class library Models
,Repository
,Notification
.
I use Models
and Repository
in Notification
class library.
Then:
Models
library project, then BUILD solution.
In the below screen shot, refer to the time stamp of DLL, EXE is updated in Models
and Notification
library.BuildRebuildClean
. What it does is deletes all the assemblies,
EXEs and referred files to compile again.I believe however if you combine all of your statements and run it in Java 8.1 you will get a different answer, at least that's what my experience says.
The code will work like this:
int a=5,i;
i=++a + ++a + a++; /*a = 5;
i=++a + ++a + a++; =>
i=6 + 7 + 7; (a=8); i=20;*/
i=a++ + ++a + ++a; /*a = 5;
i=a++ + ++a + ++a; =>
i=8 + 10 + 11; (a=11); i=29;*/
a=++a + ++a + a++; /*a=5;
a=++a + ++a + a++; =>
a=12 + 13 + 13; a=38;*/
System.out.println(a); //output: 38
System.out.println(i); //output: 29
Opening SSMS as Administrator and running as SQL Auth vs Windows Auth did not work.
What worked was to just change my filename to the same location where the LDF and MDF files are located.
alter database MyDB
add file ( name = N'FileStreamName',
filename = N'D:\SQL Databases\FileStreamSpace' )
to filegroup DocumentFiles;
What about defining an empty array as fallback if get_value()
is empty?
I can't think of a shortest way.
$values = get_values() ?: [];
foreach ($values as $value){
...
}
I would create an object like this:
var options = {
size: ["S", "M", "L", "XL", "XXL"],
color: ["Red", "Blue", "Green", "White", "Black"]
};
alert(Object.keys(options));
To access the keys individualy:
for (var key in options) {
alert(key);
}
P.S.: when you create a new array object do not use new Array
use []
instead.
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
Java 8 takes more than 1/64th of your physical memory for your Xmssize (Minimum HeapSize) and less than 1/4th of your physical memory for your -Xmxsize (Maximum HeapSize).
You can check the default Java heap size by:
In Windows:
java -XX:+PrintFlagsFinal -version | findstr /i "HeapSize PermSize ThreadStackSize"
In Linux:
java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'
What system configuration settings influence the default value?
The machine's physical memory & Java version.
You can try RESS (RESponsive design + Server side components), see this tutorial:
myString = myString.Remove(myString.Length - 3, 3);
But you could make an own link for every from url.
Example: http://example.com?auth=holasite
In this example your site is: example.com
If somebody open that link it's give you the holasite value for the auth variable.
Then just $_GET['auth'] and you have the variable. But you should have a database to store it, and to authorize.
Like: $holasite = http://holasite.com (You could use mysql too..)
And just match it, and you have the url.
This method is a little bit more complicated, but it works. This method is good for a referral system authentication. But where is the site name, you should write an id, and works with that id.
Actualy you don't need an internet connection to use ip address. Each computer in LAN has an internal IP address you can discover by runing
ipconfig /all
in cmd.
You can use the ip address of the server (probabily something like 192.168.0.x or 10.0.0.x) to access the website remotely.
If you found the ip and still cannot access the website, it means WAMP is not configured to respond to that name ( what did you call me? 192.168.0.3? That's not my name. I'm Localhost ) and you have to modify ....../apache/config/httpd.conf
Listen *:80
Try using this
this.getClass().getCanonicalName()
or this.getClass().getSimpleName()
. If it's an anonymous class, use this.getClass().getSuperclass().getName()

Well there's no difference between the first two - they're just using different names for the type parameter (E
or T
).
The third isn't a valid declaration - ?
is used as a wildcard which is used when providing a type argument, e.g. List<?> foo = ...
means that foo
refers to a list of some type, but we don't know what.
All of this is generics, which is a pretty huge topic. You may wish to learn about it through the following resources, although there are more available of course:
You need to put that code into the constructor of your class:
private Reminders reminder = new Reminders();
private dynamic defaultReminder;
public YourClass()
{
defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}
The reason is that you can't use one instance variable to initialize another one using a field initializer.

Neat and pure:
[[0, 1], [2, 3], [4, 5]].reduce((prev, next) => next.map((item, i) =>
(prev[i] || []).concat(next[i])
), []); // [[0, 2, 4], [1, 3, 5]]
Previous solutions may lead to failure in case an empty array is provided.
Here it is as a function:
function transpose(array) {
return array.reduce((prev, next) => next.map((item, i) =>
(prev[i] || []).concat(next[i])
), []);
}
console.log(transpose([[0, 1], [2, 3], [4, 5]]));
Update. It can be written even better with spread operator:
const transpose = matrix => matrix.reduce(
($, row) => row.map((_, i) => [...($[i] || []), row[i]]),
[]
)
Answer in short: (search your situation)
Although fractional pixels may appear to round up on individual elements (as @SkillDrick demonstrates very well) it's important to know that the fractional pixels are actually respected in the actual box model.
This can best be seen when elements are stacked next to (or on top of) each other; in other words, if I were to place 400 0.5 pixel divs side by side, they would have the same width as a single 200 pixel div. If they all actually rounded up to 1px (as looking at individual elements would imply) we'd expect the 200px div to be half as long.
This can be seen in this runnable code snippet:

I think this is just a simple select statement. I hope it works, because I couldn't test it at home, because I don't have a Oracle database here ;-)
select to_date('201118', 'YYYYWW'), to_date('201118', 'YYYYWW')+7 from dual;
You have to be carefully because there is a difference between WW and IW. Here is an article which explains the difference: http://rwijk.blogspot.com/2008/01/date-format-element-ww.html
One caveat! If you want to compose this via OR or AND you cannot use it in this form:
-myfield:*
but you must use
(*:* NOT myfield:*)
This form is perfectly composable. Apparently SOLR will expand the first form to the second, but only when it is a top node. Hope this saves you some time!
Make sure your two build.gradle and settings.gradle files are in the correct directories as stated in https://developer.android.com/studio/build/index.html
Then open "as existing project" in Visual Studio
Gradle is very finicky about this.
Look at the START command, you can do this:
START rest-of-your-program-name
For instance, this batch-file will wait until notepad exits:
@echo off
notepad c:\test.txt
However, this won't:
@echo off
start notepad c:\test.txt
Personally, I use Charles for that kind of stuff.
When enabled, it will monitor every network request, displaying extended request details, including support for SSL and various request/reponse format, like JSON, etc...
You can also configure it to sniff only requests to specific servers, not the whole traffic.
It's commercial software, but there is a trial, and IMHO it's definitively a great tool.
Came across the question myself today. I think the reason that your code returns 'None' (exactly what I got by using the same method) is that
a.sort()
is calling the sort function to mutate the list a. In my understanding, this is a modification command. To see the result you have to use print(a).
My solution, as I tried to keep everything in pandas:
pd.Series(df['A'].unique()).sort_values()
$( "#dialogueForm" ).dialog({
autoOpen: false,
height: "auto",
width: "auto",
modal: true,
my: "center",
at: "center",
of: window,
close : function(){
// functionality goes here
}
});
"close" property of dialog gives the close event for the same.
The best solution is to just do webView.loadUrl( "javascript:window.location.reload( true )" );
. This should work on all versions and doesn't introduce new history entries.
I always seem to use svn copy as a server operation so not sure if it works with two working paths.
Here is an example of restoring a deleted file into a local working copy of the project:
svn copy https://repos/project/modules/module.js@3502 modules/module.js
While being inside the project directory. This works as well for restoring entire directories.
I had to do this in a VB.Net 2.0 Web Service. I ended up specifying the parameters as strings, then converting them to whatever I needed. An optional parameter was specified with an empty string. Not the cleanest solution, but it worked. Just be careful that you catch all the exceptions that can occur.
You cannot directly create a table stored as a sequence file and insert text into it. You must do this:
Example:
CREATE TABLE test_txt(field1 int, field2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';
LOAD DATA INPATH '/path/to/file.tsv' INTO TABLE test_txt;
CREATE TABLE test STORED AS SEQUENCEFILE
AS SELECT * FROM test_txt;
DROP TABLE test_txt;

All these answers are wrong!!! If you are trying to put a listview in a scroll view you should re-think your design. You are trying to put a ScrollView in a ScrollView. Interfering with the list will hurt list performance. It was designed to be like this by Android.
If you really want the list to be in the same scroll as the other elements, all you have to do is add the other items into the top of the list using a simple switch statement in your adapter:
class MyAdapter extends ArrayAdapter{
public MyAdapter(Context context, int resource, List objects) {
super(context, resource, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewItem viewType = getItem(position);
switch(viewType.type){
case TEXTVIEW:
convertView = layouteInflater.inflate(R.layout.textView1, parent, false);
break;
case LISTITEM:
convertView = layouteInflater.inflate(R.layout.listItem, parent, false);
break; }
return convertView;
}
}
The list adapter can handle everything since it only renders what is visible.
document.ready (jQuery) document.ready will execute right after the HTML document is loaded property, and the DOM is ready.
DOM: The Document Object Model (DOM) is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML and XML documents.
$(document).ready(function()
{
// executes when HTML-Document is loaded and DOM is ready
alert("(document).ready was called - document is ready!");
});
window.load (Built-in JavaScript) The window.load however will wait for the page to be fully loaded, this includes inner frames, images etc. * window.load is a built-in JavaScript method, it is known to have some quirks in old browsers (IE6, IE8, old FF and Opera versions) but will generally work in all of them.
window.load can be used in the body's onload event like this (but I would strongly suggest you avoid mixing code like this in the HTML, as it is a source for confusion later on):
$(window).load(function()
{
// executes when complete page is fully loaded, including all frames, objects and images
alert("(window).load was called - window is loaded!");
});
NOTE: All algorithms below are in C, but should be portable to your language of choice (just don't look at me when they're not as fast :)

unsigned int v; // reverse 32-bit value, 8 bits at time

You can extend this idea to 64-bit int
s, or trade off memory for speed (assuming your L1 Data Cache is large enough), and reverse 16 bits at a time with a 64K-entry lookup table.
Simple
unsigned int v; // input bits to be reversed
unsigned int r = v & 1; // r will be reversed bits of v; first get LSB of v
int s = sizeof(v) * CHAR_BIT - 1; // extra shift needed at end
for (v >>= 1; v; v >>= 1)
{
r <<= 1;
r |= v & 1;
s--;
}
r <<= s; // shift when v's highest bits are zero
Faster (32-bit processor)
unsigned char b = x;
b = ((b * 0x0802LU & 0x22110LU) | (b * 0x8020LU & 0x88440LU)) * 0x10101LU >> 16;
Faster (64-bit processor)
unsigned char b; // reverse this (8-bit) byte
b = (b * 0x0202020202ULL & 0x010884422010ULL) % 1023;
If you want to do this on a 32-bit int
, just reverse the bits in each byte, and reverse the order of the bytes. That is:
unsigned int toReverse;
unsigned int reversed;
unsigned char inByte0 = (toReverse & 0xFF);
unsigned char inByte1 = (toReverse & 0xFF00) >> 8;
unsigned char inByte2 = (toReverse & 0xFF0000) >> 16;
unsigned char inByte3 = (toReverse & 0xFF000000) >> 24;
reversed = (reverseBits(inByte0) << 24) | (reverseBits(inByte1) << 16) | (reverseBits(inByte2) << 8) | (reverseBits(inByte3);
I benchmarked the two most promising solutions, the lookup table, and bitwise-AND (the first one). The test machine is a laptop w/ 4GB of DDR2-800 and a Core 2 Duo T7500 @ 2.4GHz, 4MB L2 Cache; YMMV. I used gcc 4.3.2 on 64-bit Linux. OpenMP (and the GCC bindings) were used for high-resolution timers.

I tried both approaches at several different optimizations, ran 3 trials at each level, and each trial reversed 100 million random unsigned ints
. For the lookup table option, I tried both schemes (options 1 and 2) given on the bitwise hacks page. Results are shown below.

Use the lookup table, with option 1 (byte addressing is unsurprisingly slow) if you're concerned about performance. If you need to squeeze every last byte of memory out of your system (and you might, if you care about the performance of bit reversal), the optimized versions of the bitwise-AND approach aren't too shabby either.
Yes, I know the benchmark code is a complete hack. Suggestions on how to improve it are more than welcome. Things I know about:
ld

EDIT: I also tried using uint64_t
types on my machine to see if there was any performance boost. Performance was about 10% faster than 32-bit, and was nearly identical whether you were just using 64-bit types to reverse bits on two 32-bit int
types at a time, or whether you were actually reversing bits in half as many 64-bit values. The assembly code is shown below (for the former case, reversing bits for two 32-bit int
types at a time):

It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:
When location matches the last part of the directive’s value: it is better to use the root directive instead:
which would yield:
server {
listen 8080;
server_name www.mysite.com mysite.com;
error_log /home/www-data/logs/nginx_www.error.log;
error_page 404 /404.html;
location /public/doc/ {
autoindex on;
root /home/www-data/mysite;
}
location = /404.html {
root /home/www-data/mysite/static/html;
}
}
There is jq
for parsing json on the command line:
jq '.Body'
Visit this for jq: https://stedolan.github.io/jq/
When I'm just testing a string to see if it is a GUID, I don't really want to create a Guid object that I don't need. So...
public static class GuidEx
{
public static bool IsGuid(string value)
{
Guid x;
return Guid.TryParse(value, out x);
}
}
And here's how you use it:
string testMe = "not a guid";
if (GuidEx.IsGuid(testMe))
{
...
}
You might have to move the mouse to any particular location after context click() like this -
Actions action = new Actions(driver);
actions.contextClick(link).moveByOffset(x,y).click().build().perform();
To understand how moveByOffset(x,y) works look here;
I hope this works. You will have to calculate the offset values for x and y;
best way would be to find the size of each option button after right clicking and then if you click on the 2nd option .
x = width of option button/2
y = 2*(size of each option button)
It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.
Try this. The following considers checkbox and label as a unique element:
<style>
.item {white-space: nowrap;display:inline }
</style>
<fieldset>
<div class="item">
<input type="checkbox" id="a">
<label for="a">aaaaaaaaaaaa aaaa a a a a a a aaaaaaaaaaaaa</label>
</div>
<div class="item">
<input type="checkbox" id="b">
<!-- depending on width, a linebreak NEVER occurs here. -->
<label for="b">bbbbbbbbbbbb bbbbbbbbbbbbbbbbb b b b b bb</label>
</div>
<div class="item">
<input type="checkbox" id="c">
<label for="c">ccccc c c c c ccccccccccccccc cccc</label>
</div>
</fieldset>
Add item to list in the begining
$("#ddlList").prepend('<option selected="selected" value="0"> Select </option>');
Add item to list in the end
$('<option value="6">Java Script</option>').appendTo("#ddlList");
Common Dropdown operation (Get, Set, Add, Remove) using jQuery
Below is the method using RouteData to style menuBar items depending of the current route:
RouteConfig includes data with tab (current route):
@RouteConfig([
{
path: '/home', name: 'Home', component: HomeComponent,
data: {activeTab: 'home'}, useAsDefault: true
}, {
path: '/jobs', name: 'Jobs', data: {activeTab: 'jobs'},
component: JobsComponent
}
])
A piece of layout:
<li role="presentation" [ngClass]="{active: isActive('home')}">
<a [routerLink]="['Home']">Home</a>
</li>
<li role="presentation" [ngClass]="{active: isActive('jobs')}">
<a [routerLink]="['Jobs']">Jobs</a>
</li>
Class:
export class MainMenuComponent {
router: Router;
constructor(data: Router) {
this.router = data;
}
isActive(tab): boolean {
if (this.router.currentInstruction && this.router.currentInstruction.component.routeData) {
return tab == this.router.currentInstruction.component.routeData.data['activeTab'];
}
return false;
}
}
Sometimes, Clover is configured to provide code coverage reports for all non-test code. If you wish to override these preferences, you may use configuration elements to exclude and include source files from being instrumented:
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-clover2-plugin</artifactId>
<version>${clover-version}</version>
<configuration>
<excludes>
<exclude>**/*Dull.java</exclude>
</excludes>
</configuration>
</plugin>
Also, you can include the following Sonar configuration:
<properties>
<sonar.exclusions>
**/domain/*.java,
**/transfer/*.java
</sonar.exclusions>
</properties>
sys.argv
to get the command-line parametersopen()
, read()
to manipulate fileYou might be looking for IgnoreDataMemberAttribute
.
<p><b> BOLD TEXT </b> not in bold </p>;
Include the text you want to be in bold between <b>...</b>
As a one-liner into vim:
:set tabstop=4 shiftwidth=4
For permanent setup, add these lines to ~/.vimrc:
set tabstop=4
set shiftwidth=4
NOTE: Add set expandtab
if you prefer 4-spaces indentation, instead of a tab indentation.
This is very simple, you just need to add a background image to the select element and position it where you need to, but don't forget to add:
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
According to http://shouldiprefix.com/#appearance
Microsoft Edge and IE mobile support this property with the -webkit- prefix rather than -ms- for interop reasons.
I just made this fiddle http://jsfiddle.net/drjorgepolanco/uxxvayqe/
You can used two way.
First Way:
Set android:inputType="textCapSentences"
on your EditText.
Second Way:
When user enter the number you have to used text watcher and change small to capital letter.
edittext.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable et) {
String s=et.toString();
if(!s.equals(s.toUpperCase()))
{
s=s.toUpperCase();
edittext.setText(s);
edittext.setSelection(edittext.length()); //fix reverse texting
}
}
});
I use the following function. It is not the most memory efficient but it is very simple to understand, supports multiple compare methods, is only 4 lines, is fast, mostly works in VBA too, will find not just individual characters but any search string (I often search for VbCrLf (s)).
Only thing missing is the ability to start search from a different "Start"
Function inStC(myInput As String, Search As String, Optional myCompareMethod As Long = CompareMethod.Text) As Long
If InStr(1, myInput, Search, myCompareMethod) = 0 Then Return 0
Return UBound(Split(myInput, Search,, myCompareMethod))
End Function
One thing I like is that it is compact to use example.
str="the little red hen"
count=inStC(str,"e") 'count should equal 4
count=inStC(str,"t") 'count should equal 3
While I am here, I would like to shill my inStB function, which, instead of returning a count of a string, it will simply return a boolean if the search string is present. I need this function often and this makes my code cleaner.
Function inStB(myInput As String, Search As String, Optional Start As Long = 1, Optional myCompareMethod As Long = CompareMethod.Text) As Boolean
If InStr(Start, myInput, Search, myCompareMethod) > 0 Then Return True
Return False
End Function
had the problem with using the JDBC driver, so one just has to add the database (maybe redundantly depending on the tool you may use) after the host name in the URL, e.g.
jdbc:postgres://<host(:port)>/<db-name>
further details are documented here: http://www.postgresql.org/docs/7.4/static/jdbc-use.html#JDBC-CONNECT
You don't need to parse the string, it's defined as a string already.
Just do:
private static String getStringInput (String prompt) {
String input = EZJ.getUserInput(prompt);
return input;
}
Thanks to @Rob M. for his help. This is what the final block of code looked like:
function swapper() {
toggleClass(document.getElementById('overlay'), 'open');
}
var el = document.getElementById('overlayBtn');
if (el){
el.addEventListener('click', swapper, false);
var text = document.getElementById('overlayBtn');
text.onclick = function(){
this.innerHTML = (this.innerHTML === "Menu") ? "Close" : "Menu";
return false;
};
}
You would use the replace
method:
text = text.replace('old', 'new');
The first argument is what you're looking for, obviously. It can also accept regular expressions.
Just remember that it does not change the original string. It only returns the new value.
The difference between a string (or to be precise, std::string
) and a character literal is that for the latter there is no +
operator defined. This is why the second example fails.
In the first case, the compiler can find a suitable operator+
with the first argument being a string
and the second a character literal (const char*
) so it used that. The result of that operation is again a string
, so it repeats the same trick when adding "!"
to it.
To expand on the above answercopied by Shakti, I have actually been able to measure a performance difference between the two functions.
I was testing performance of variations of the solution to this question and found that the standard deviation and maximum runtimes were larger when using CAST
.
*Times in milliseconds, rounded to nearest 1/300th of a second as per the precision of the DateTime
type
Following this guide I had the same issue. To expand on Eric Moore's ridiculously vague answer,
Right click > TortoiseGit > Settings > Network
Down the bottom in the "SSH" section, hit Browse and find your TortoiseGit\bin\TortoisePlink.exe
file. In my case the path was under Programs
as opposed to Program Files
You can use regular expressions. Use Matcher and Pattern methods to get the desired output
Try writing all the errors to a file.
error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
Something like that.
char *
and const unsigned char *
are considered unrelated types. So you want to use reinterpret_cast
.
But if you were going from const unsigned char*
to a non const
type you'd need to use const_cast
first. reinterpret_cast
cannot cast away a const
or volatile
qualification.
It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:
If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.
So I think in your example, the server should return a 416 since it's not a valid byte range for that file.
Isn't just Python doing round half to even, as prescribed by IEEE 754?
Be careful redefining, or using "non-standard" rounding…

The python shutil.copytree method its a mess. I've done one that works correctly:
def copydirectorykut(src, dst):
os.chdir(dst)
list=os.listdir(src)
nom= src+'.txt'
fitx= open(nom, 'w')
for item in list:
fitx.write("%s\n" % item)
fitx.close()
f = open(nom,'r')
for line in f.readlines():
if "." in line:
shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
else:
if not os.path.exists(dst+'/'+line[:-1]):
os.makedirs(dst+'/'+line[:-1])
copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
f.close()
os.remove(nom)
os.chdir('..')
I always use Ctrl+Shift+F5 out of habit, it should force a full-refresh including by-passing any http proxies you may be going through.
Here you go: ES5
var test = 'Hello World';
if( test.indexOf('World') >= 0){
// Found world
}
With ES6 best way would be to use includes
function to test if the string contains the looking work.
const test = 'Hello World';
if (test.includes('World')) {
// Found world
}
use extent with custom function to handle multiple inheritance with es6

I prefer

over
<label for="firstname">Firstname</label>
<input name="firstname" id="firstname" />
<label for="lastname">Lastname</label>
<input name="lastname" id="lastname" />
Mainly because it makes the HTML more readable. And I actually think my first example is easier to style with CSS, as CSS works very well with nested elements.
But it's a matter of taste I suppose.
If you need more styling options, add a span tag.
<label>
<span>Firstname</span>
<input name="firstname" />
</label>
<label>
<span>Lastname</span>
<input name="lastname" />

Code still looks better in my opinion.

Is a completely different (but still free) application an option? I use HxD, and it serves me better than the Notepad++ plugin. It can calculate hashes, open memory of a process, it is fast at opening files of any size, and it works exceptionally well with the clipboard.
I used to use the Notepad++ plugin, but not anymore.
In Visual Studio 2012, the same can be done using the "Sync With Active Document" option in Solution Explorer

1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.Here is an end to end solution I implemented for streaming Android microphone audio to a server for playback: Android AudioRecord to Server over UDP Playback Issues
Use:
https://www.googleapis.com/youtube/v3/videoCategories?part=snippet,id&maxResults=100®ionCode=us&key=**Your YouTube ID**
Above is the link. Using that, you can find the YouTube characteristics of videos. After finding characteristics, you can get videos of the selected category. After then you can find selected video images using Asaph's answer.
Try the above approach and you can parse everything from the YouTube API.
Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.
First, click Slide Show > Set Up Show.
Put a checkmark to Loop continuously until 'Esc'.
Click Ok. Now, Click Slide Show > Custom Shows. Click New.
Select the slide you are looping, click Add. Click Ok and Close.
Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.
Right click on the thumbnail of the current slide, select Hide Slide.
Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"
This has worked for me.
Haven't seen this solution yet so here's how I did it without using read_csv:
df.rename(columns={'A':'','B':''})
If you rename all your column names to empty strings your table will return without a header.
And if you have a lot of columns in your table you can just create a dictionary first instead of renaming manually:
df_dict = dict.fromkeys(df.columns, '')
df.rename(columns = df_dict)
