If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc
This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array
import numpy as np
from sklearn.metrics import auc
dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)
print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))
both output the same area: 4607.5
the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect
IMHO you can't compare SOAP and REST where those are two different things.
SOAP is a protocol and REST is a software architectural pattern. There is a lot of misconception in the internet for SOAP vs REST.
SOAP defines XML based message format that web service-enabled applications use to communicate each other over the internet. In order to do that the applications need prior knowledge of the message contract, datatypes, etc..
REST represents the state(as resources) of a server from an URL.It is stateless and clients should not have prior knowledge to interact with server beyond the understanding of hypermedia.

Update: this was fixed in Firefox v35. See the full gist for details.
== how to hide the select arrow in Firefox ==
Just figured out how to do it. The trick is to use a mix of -prefix-appearance
, text-indent
and text-overflow
. It is pure CSS and requires no extra markup.
select {
-moz-appearance: none;
text-indent: 0.01px;
text-overflow: '';
}
Long story short, by pushing it a tiny bit to the right, the overflow gets rid of the arrow. Pretty neat, huh?
More details on this gist I just wrote. Tested on Ubuntu, Mac and Windows, all with recent Firefox versions.

Solutions listed did not exactly work for me. The closest was Chief Wiggum - I wanted to add a comment on his answer but lack the reputation to do so. So I post as separate answer:
=MIN(IF(A1:E1>0;A1:E1))
Then instead of pressing ENTER, press CTRL+SHIFT+ENTER and watch Excel add {
and }
to respectively the beginning and the end of the formula (to activate the formula on array).
The comma "," and "If" statement as proposed by Chief Wiggum did not work on Excel Home and Student 2013. Need a semicolon ";" as well as full cap "IF" did the trick. Small syntax difference but took me 1.5 hour to figure out why I was getting an error and #VALUE.
Please read this docs from the Guido First Class everything Clearly explained how Unbound, Bound methods are born.
Another way to suppress the error: Add this line at the top in C/C++ file:

result.score = 3.14159265358979
print(result.score) // 3.1416
This can be achieved by assigning the header view manually in the UITableViewController's viewDidLoad method instead of using the delegate's viewForHeaderInSection and heightForHeaderInSection. For example in your subclass of UITableViewController, you can do something like this:
- (void)viewDidLoad {
[super viewDidLoad];
UILabel *headerView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 40)];
[headerView setBackgroundColor:[UIColor magentaColor]];
[headerView setTextAlignment:NSTextAlignmentCenter];
[headerView setText:@"Hello World"];
[[self tableView] setTableHeaderView:headerView];
}
The header view will then disappear when the user scrolls. I don't know why this works like this, but it seems to achieve what you're looking to do.
The account that sql server is running under does not have access to the location where you have the backup file or are trying to restore the database to. You can use SQL Server Configuration Manager to find which account is used to run the SQL Server instance, and then make sure that account has full control over the .BAK file and the folder where the MDF will be restored to.
Why not JSON.stringify
and .includes()
?
You can easily check if a JSON object includes a value by turning it into a string and checking the string.
console.log(JSON.stringify(JSONObject).includes("dog"))
--> true
Edit: make sure to check browser compatibility for .includes()

Are you talking about automated unit/integration tests or manual tests?
For the former, my rule of thumb (based on measurements) is 40-50% added to development time i.e. if developing a use case takes 10 days (before an QA and serious bugfixing happens), writing good tests takes another 4 to 5 days - though this should best happen before and during development, not afterwards.
you can use the custom datetime by using...
create table noteTable3
(created_at DATETIME DEFAULT (STRFTIME('%d-%m-%Y %H:%M', 'NOW','localtime')),
title text not null, myNotes text not null);
use 'NOW','localtime' to get the current system date else it will show some past or other time in your Database after insertion time in your db.

If there is no vertical scrolling then you can use position:absolute
and height:100%
declared on html and body elements.
Another option is to use viewport height units, see Make div 100% height of browser window
Absolute position Example:

height:100%;_x000D_
position: absolute;_x000D_
background-color:red;_x000D_
}_x000D_
.button{_x000D_
height:50%;_x000D_
background-color:white;_x000D_
}
_x000D_
<div class="button">BUTTON</div>

In addition to Sophie's answer, I also have found a use in sending in child component types, doing something like this:
var ListView = React.createClass({
render: function() {
var items = this.props.data.map(function(item) {
return this.props.delegate({data:item});
}.bind(this));
return <ul>{items}</ul>;
}
});
var ItemDelegate = React.createClass({
render: function() {
return <li>{this.props.data}</li>
}
});
var Wrapper = React.createClass({
render: function() {
return <ListView delegate={ItemDelegate} data={someListOfData} />
}
});
Using regex, the result is in $matches[1]:
$str = "test.txt ; 131 136 80 89 119 17 60 123 210 121 188 42 136 200 131 198"
$str -match "^(.*?)\s\;"
$matches[1]
test.txt

If you have a function which must be passed a signed byte, what do you expect it to do if you pass an unsigned byte?
Why can't you use any other data type?
Unsually you can use a byte as an unsigned byte with simple or no translations. It all depends on how it is used. You would need to clarify what you indend to do with it.

With .Net Core it is now very easy:
char
means exactly one character. You can't assign zero characters to this type.
That means that there is no char value for which String.replace(char, char)
would return a string with a diffrent length.
No. Class variables(Also applicable to instance variables) don't exhibit overriding feature in Java as class variables are invoked on the basis of the type of calling object. Added one more class(Human) in the hierarchy to make it more clear. So now we have
Son extends Dad extends Human
In the below code, we try to iterate over an array of Human, Dad and Son objects, but it prints Human Class’s values in all cases as the type of calling object was Human.
class Human
{
static String me = "human";
public void printMe()
{
System.out.println(me);
}
}
class Dad extends Human
{
static String me = "dad";
}
class Son extends Dad
{
static String me = "son";
}
public class ClassVariables {
public static void main(String[] abc) {
Human[] humans = new Human[3];
humans[0] = new Human();
humans[1] = new Dad();
humans[2] = new Son();
for(Human human: humans) {
System.out.println(human.me); // prints human for all objects
}
}
}
Will print
So no overriding of Class variables.
If we want to access the class variable of actual object from a reference variable of its parent class, we need to explicitly tell this to compiler by casting parent reference (Human object) to its type.
System.out.println(((Dad)humans[1]).me); // prints dad
System.out.println(((Son)humans[2]).me); // prints son
Will print
On how part of this question:- As already suggested override the printMe() method in Son class, then on calling
Son().printMe();
Dad's Class variable "me" will be hidden because the nearest declaration(from Son class printme() method) of the "me"(in Son class) will get the precedence.
document.documentElement.classList.add('myCssClass');
classList

Taking a stab at this. Kind of hard to measure performance, though.
function palin(word) {
var i = 0,
len = word.length - 1,
max = word.length / 2 | 0;
while (i < max) {
if (word.charCodeAt(i) !== word.charCodeAt(len - i)) {
return false;
}
i += 1;
}
return true;
}
My thinking is to use charCodeAt()
instead charAt()
with the hope that allocating a Number
instead of a String
will have better perf because String
s are variable length and might be more complex to allocate. Also, only iterating halfway through (as noted by sai) because that's all that's required. Also, if the length is odd (ex: 'aba'
), the middle character is always ok.
The correct way to do this is:
typedef void (*callback_function)(void); // type for conciseness
callback_function disconnectFunc; // variable to store function pointer type
void D::setDisconnectFunc(callback_function pFunc)
{
disconnectFunc = pFunc; // store
}
void D::disconnected()
{
disconnectFunc(); // call
connected = false;
}
Java does not have unsigned types. As already mentioned, incure the overhead of BigInteger or use JNI to access native code.
//smalest number in the array//
double small = x[0];
for(t=0;t<x[t];t++)
{
if(x[t]<small)
{
small=x[t];
}
}
printf("\nThe smallest number is %0.2lf \n",small);

NEVER USE VLOOKUP. It's one of the worst performing formulas in excel. Use index match instead. It even works without sorting data, unless you have a -1 or 1 in the end of the match formula (explained more below)
Here is a link with the appropriate formulas.
The Sheet 2 formula would be this: =IF(A2="","",INDEX(Sheet1!B:B,MATCH($A2,Sheet1!$A:$A,0)))
More information on the Index/Match formula
Other fun facts: $ means absolute in a formula. So if you specify $B$1 when filling a formula down or over keeps that same value. If you over $B1, the B remains the same across the formula, but if you fill down, the 1 increases with the row count. Likewise, if you used B$1, filling to the right will increment the B, but keep the reference of row 1.
I also included the use of indirect in the second section. What indirect does is allow you to use the text of another cell in a formula. Since I created a named range sheet1!A:A = ID, sheet1!B:B = Name, and sheet1!C:C=Price, I can use the column name to have the exact same formula, but it uses the column heading to change the search criteria.
Good luck! Hope this helps.

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.
That is neither a good idea in terms of peformance nor in terms of fail-safety.
There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:
In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.
Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.
So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.
So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.
If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).
Conclusion:
using-statement
to dispose and close(in case of Connections) implicitelyThat's true not only for Connections(although most noticable). Every object implementing IDisposable
should be disposed(simplest by using-statement
), all the more in the System.Data.SqlClient
namespace.
All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.
Edit: Here's a possible implementation of your retrievePromotion
-method:
public Promotion retrievePromotion(int promotionID)
{
Promotion promo = null;
var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
using (SqlConnection connection = new SqlConnection(connectionString))
{
var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
using (var da = new SqlDataAdapter(queryString, connection))
{
// you could also use a SqlDataReader instead
// note that a DataTable does not need to be disposed since it does not implement IDisposable
var tblPromotion = new DataTable();
// avoid SQL-Injection
da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
try
{
connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise
da.Fill(tblPromotion);
if (tblPromotion.Rows.Count != 0)
{
var promoRow = tblPromotion.Rows[0];
promo = new Promotion()
{
promotionID = promotionID,
promotionTitle = promoRow.Field<String>("PromotionTitle"),
promotionUrl = promoRow.Field<String>("PromotionURL")
};
}
}
catch (Exception ex)
{
// log this exception or throw it up the StackTrace
// we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
throw;
}
}
}
return promo;
}
You can't run PHP with javascript. JavaScript is a client side technology (runs in the users browser) and PHP is a server side technology (run on the server).

I believe that sorting by the column you want to get the MAX of and then grabbing the first should work. However, if there are multiple objects with the same MAX value, only one will be grabbed:
private void Test()
{
test v1 = new test();
v1.Id = 12;
test v2 = new test();
v2.Id = 12;
test v3 = new test();
v3.Id = 12;
List<test> arr = new List<test>();
arr.Add(v1);

I made another variant with dropdown menu (perhaps for advanced search etc).. Here is how it looks like:
<div class="input-group my-4 col-6 mx-auto">
<input class="form-control py-2 border-right-0 border" type="search" placeholder="Type something..." id="example-search-input">
<span class="input-group-append">
<button type="button" class="btn btn-outline-primary dropdown-toggle dropdown-toggle-split border border-left-0 border-right-0 rounded-0" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<button class="btn btn-outline-primary rounded-right" type="button">
<i class="fas fa-search"></i>
</button>
<div class="dropdown-menu dropdown-menu-right">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div role="separator" class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</span>
</div>
Note: It appears green in the screenshot because my site main theme is green.
The first one. Those file paths are relative from where your .gitignore file is.
I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;
It works and it's cross browser compatible.

setting management.security.enabled=false
in application.properties
resolved the issue for me.
To write a newline use \n
not /n
the latter is just a slash and a n
tick_params is very useful for setting tick properties. Labels can be moved to the top with:
ax.tick_params(labelbottom=False,labeltop=True)
If you use Start-Process <path to exe> -NoNewWindow -Wait
You can also use the -PassThru
option to echo output.
Python 3.6 introduced f-strings for inline interpolation. What's even nicer is it extended the syntax to also allow format specifiers with interpolation. Something I've been working on while I googled this (and came across this old question!):
print(f'{account:40s} ({ratio:3.2f}) -> AUD {splitAmount}')
PEP 498 has the details. And... it sorted my pet peeve with format specifiers in other langs -- allows for specifiers that themselves can be expressions! Yay! See: Format Specifiers.
ALTER TABLE
listing
ADDcount
INT(5), ADDlog
VARCHAR(200), ADDstatus
VARCHAR(20) AFTER stat
It will give good results.
You can use Zend_Debug::Dump($select->assemble());
to get the SQL query.
Or you can enable Zend DB FirePHP profiler which will get you all queries in a neat format in Firebug (even UPDATE statements).
EDIT: Profiling with FirePHP also works also in FF6.0+ (not only in FF3.0 as suggested in link)
As already stated, overloading in the sense that you mean isn't supported by C. A common idiom to solve the problem is making the function accept a tagged union. This is implemented by a struct
parameter, where the struct
itself consists of some sort of type indicator, such as an enum
, and a union
of the different types of values. Example:
#include <stdio.h>
typedef enum {
T_INT,
T_FLOAT,
T_CHAR,
} my_type;
typedef struct {
my_type type;
union {
int a;
float b;
char c;
} my_union;
} my_struct;
void set_overload (my_struct *whatever)
{
switch (whatever->type)
{
case T_INT:
whatever->my_union.a = 1;
break;
case T_FLOAT:
whatever->my_union.b = 2.0;
break;
case T_CHAR:
whatever->my_union.c = '3';
}
}
void printf_overload (my_struct *whatever) {
switch (whatever->type)
{
case T_INT:
printf("%d\n", whatever->my_union.a);
break;
case T_FLOAT:
printf("%f\n", whatever->my_union.b);
break;
case T_CHAR:
printf("%c\n", whatever->my_union.c);
break;
}
}
int main (int argc, char* argv[])
{
my_struct s;
s.type=T_INT;
set_overload(&s);
printf_overload(&s);
s.type=T_FLOAT;
set_overload(&s);
printf_overload(&s);
s.type=T_CHAR;
set_overload(&s);
printf_overload(&s);
}
The /EXCLUDE:
argument expects a file containing a list of excluded files.
So create a file called excludedfileslist.txt
containing:
.cs\
Then a command like this:
xcopy /r /d /i /s /y /exclude:excludedfileslist.txt C:\dev\apan C:\web\apan
Alternatively you could use Robocopy, but would require installing / copying a robocopy.exe
to the machines.
An anonymous comment edit which simply stated "This Solution exclude also css file!"
This is true creating a excludedfileslist.txt
file contain just:
.cs
(note no backslash on the end)
Will also exclude all of the following:
file1.cs
file2.css
dir1.cs\file3.txt
dir2\anyfile.cs.something.txt
Sometimes people don't read or understand the XCOPY command's help, here is an item I would like to highlight:
Using /exclude
- List each string in a separate line in each file. If any of the listed strings match any part of the absolute path of the file to be copied, that file is then excluded from the copying process. For example, if you specify the string "\Obj\", you exclude all files underneath the Obj directory. If you specify the string ".obj", you exclude all files with the .obj extension.
As the example states it excludes "all files with the .obj extension" but it doesn't state that it also excludes files or directories named file1.obj.tmp
or dir.obj.output\example2.txt
.
There is a way around .css
files being excluded also, change the excludedfileslist.txt
file to contain just:
.cs\
(note the backslash on the end).
Here is a complete test sequence for your reference:
C:\test1>ver
Microsoft Windows [Version 6.1.7601]
C:\test1>md src
C:\test1>md dst
C:\test1>md src\dir1
C:\test1>md src\dir2.cs
C:\test1>echo "file contents" > src\file1.cs
C:\test1>echo "file contents" > src\file2.css
C:\test1>echo "file contents" > src\dir1\file3.txt
C:\test1>echo "file contents" > src\dir1\file4.cs.txt
C:\test1>echo "file contents" > src\dir2.cs\file5.txt
C:\test1>xcopy /r /i /s /y .\src .\dst
.\src\file1.cs
.\src\file2.css
.\src\dir1\file3.txt
.\src\dir1\file4.cs.txt
.\src\dir2.cs\file5.txt
5 File(s) copied
C:\test1>echo .cs > excludedfileslist.txt
C:\test1>xcopy /r /i /s /y /exclude:excludedfileslist.txt .\src .\dst
.\src\dir1\file3.txt
1 File(s) copied
C:\test1>echo .cs\ > excludedfileslist.txt
C:\test1>xcopy /r /i /s /y /exclude:excludedfileslist.txt .\src .\dst
.\src\file2.css
.\src\dir1\file3.txt
.\src\dir1\file4.cs.txt
3 File(s) copied
This test was completed on a Windows 7 command line and retested on Windows 10 "10.0.14393".
Note that the last example does exclude .\src\dir2.cs\file5.txt
which may or may not be unexpected for you.
This should work for every default repo:
git pull origin master
If your default branch is different than master
, you will need to specify the branch name:
git pull origin my_default_branch_name
const monthNames = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"];
const dateObj = new Date();
const month = monthNames[dateObj.getMonth()];
const day = String(dateObj.getDate()).padStart(2, '0');
const year = dateObj.getFullYear();
const output = month + '\n'+ day + ',' + year;
document.querySelector('.date').textContent = output;
In order to get the http status code returned from the server, you can add validateStatus: status => true
to axios options:
axios({
method: 'POST',
url: 'http://localhost:3001/users/login',
data: { username, password },
validateStatus: () => true
}).then(res => {
console.log(res.status);
});
This way, every http response resolves the promise returned from axios.
Use SpecialCells to delete only the rows that are visible after autofiltering:
ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
(xlCellTypeVisible).EntireRow.Delete
If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:
ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
(xlCellTypeVisible).EntireRow.Delete
A simple function to perform this calculation:
function getMinutesBetweenDates(startDate, endDate) {
var diff = endDate.getTime() - startDate.getTime();
return (diff / 60000);
}
I too had this issue, however nothing I tried above and in several other posts worked.. except for this.
For me, I changed the bundle identifier since we have a different bundle ID for distribution versus development.
My hardware is allowed on this provision and my team account is valid but it was throwing the above error on some other framework.
Turns out that I needed to completely remove the old version of the app completely from my phone. And not just deleting it the standard way.
Solution :
Evidently on installing the same app under the same team under a different bundle ID, if your not starting completely from scratch, there are some references to frameworks that get muddied.
Hope this helps someone.
My understanding of SQLiteDatabase APIs is that in case you have a multi threaded application, you cannot afford to have more than a 1 SQLiteDatabase object pointing to a single database.
The object definitely can be created but the inserts/updates fail if different threads/processes (too) start using different SQLiteDatabase objects (like how we use in JDBC Connection).
The only solution here is to stick with 1 SQLiteDatabase objects and whenever a startTransaction() is used in more than 1 thread, Android manages the locking across different threads and allows only 1 thread at a time to have exclusive update access.
Also you can do "Reads" from the database and use the same SQLiteDatabase object in a different thread (while another thread writes) and there would never be database corruption i.e "read thread" wouldn't read the data from the database till the "write thread" commits the data although both use the same SQLiteDatabase object.
This is different from how connection object is in JDBC where if you pass around (use the same) the connection object between read and write threads then we would likely be printing uncommitted data too.
In my enterprise application, I try to use conditional checks so that the UI Thread never have to wait, while the BG thread holds the SQLiteDatabase object (exclusively). I try to predict UI Actions and defer BG thread from running for 'x' seconds. Also one can maintain PriorityQueue to manage handing out SQLiteDatabase Connection objects so that the UI Thread gets it first.
Convert Map
to an array using Array.from
, sort array, convert back to Map
, e.g.
new Map(
Array
.from(eventsByDate)
.sort((a, b) => {
// a[0], b[0] is the key of the map
return a[0] - b[0];
})
)
Have a look at jQuery, a cross-browser library that will make your life a lot easier.
var msg = 'abc';
$('#msg').val(msg);
$('#sp_100').attr('checked', 'checked');
// Back to bottom button
$(window).scroll(function () {
var scrollBottom = $(this).scrollTop() + $(this).height();
var scrollTop = $(this).scrollTop();
var pageHeight = $('html, body').height();//Fixed
if ($(this).scrollTop() > pageHeight - 700) {
$('.back-to-bottom').fadeOut('slow');
} else {
if ($(this).scrollTop() < 100) {
$('.back-to-bottom').fadeOut('slow');
}
else {
$('.back-to-bottom').fadeIn('slow');
}
}
});
$('.back-to-bottom').click(function () {
var pageHeight = $('html, body').height();//Fixed
$('html, body').animate({ scrollTop: pageHeight }, 1500, 'easeInOutExpo');
return false;
});
How can I roll back my previous 4 commits locally in a branch?
Which means, you are not creating new branch and going into detached state. New way of doing that is:
git switch --detach revison

Sure, a Linked List is a bit confusing for programming n00bs, pretty much the temptation is to look at it as Russian Dolls, because that's what it seems like, a LinkedList Object in a LinkedList Object. But that's a touch difficult to visualize, instead look at it like a computer.
LinkedList = Data + Next Member
Where it's the last member of the list if next is NULL
So a 5 member LinkedList would be:
LinkedList(Data1, LinkedList(Data2, LinkedList(Data3, LinkedList(Data4, LinkedList(Data5, NULL)))))
But you can think of it as simply:
Data1 -> Data2 -> Data3 -> Data4 -> Data5 -> NULL
So, how do we find the end of this? Well, we know that the NULL is the end so:
public void append(LinkedList myNextNode) {
LinkedList current = this; //Make a variable to store a pointer to this LinkedList
while (current.next != NULL) { //While we're not at the last node of the LinkedList
current = current.next; //Go further down the rabbit hole.
}
current.next = myNextNode; //Now we're at the end, so simply replace the NULL with another Linked List!
return; //and we're done!
}
This is very simple code of course, and it will infinitely loop if you feed it a circularly linked list! But that's the basics.
U cant try this
for (WordList i : words) {
words.get(words.indexOf(i));
}
If you would like to not inflate another view just to indicate progress then do the following:
Android will take care the progress bar's visibility.
For example, in activity_main.xml
:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.fcchyd.linkletandroid.MainActivity">
<ListView
android:id="@+id/list_view_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@color/colorDivider"
android:dividerHeight="1dp" />
<ProgressBar
android:id="@+id/loading_progress_xml"
style="?android:attr/progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
</RelativeLayout>
And in MainActivity.java
:
package com.fcchyd.linkletandroid;

This will work as long as the image you want to rotate is already in your Properties resources folder.
In Partial Class:
Bitmap bmp2;
OnLoad:
bmp2 = new Bitmap(Tycoon.Properties.Resources.save2);
pictureBox6.SizeMode = PictureBoxSizeMode.StretchImage;
pictureBox6.Image = bmp2;
Button or Onclick
private void pictureBox6_Click(object sender, EventArgs e)
{
if (bmp2 != null)
{
bmp2.RotateFlip(RotateFlipType.Rotate90FlipNone);
pictureBox6.Image = bmp2;
}
}
I managed to solved this by adding FcgidBusyTimeout . Just in case if anyone have similar issue with me.
Here is my settings on my apache.conf:
<VirtualHost *:80>
.......
<IfModule mod_fcgid.c>
FcgidBusyTimeout 3600
</IfModule>
</VirtualHost>
I got the error when building an R package (using roxygen2)
The cause in my case was that I had saved data/mydata.RData
with saveRDS()
rather than save()
. E.g. save(iris, file="data/iris.RData")
This fixed the issue for me. I found this info here
Also note that with save()
/ load()
the object is loaded in with the same name it is initially saved with (i.e you can't rename it until it's already loaded into the R environment under the name it had when you initially saved it).
I have put this working code snippet for future references. The code sample was written with Apache velocity version 1.7 with embedded Jetty.
Velocity template path is located at the resource folder email_templates subfolder.
Code Snippet in Java (Snippets are worked both running on eclipse and inside a Jar)
templateName = "/email_templates/byoa.tpl.vm"
VelocityEngine ve = new VelocityEngine();
ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
ve.init();
Template t = ve.getTemplate(this.templateName);
VelocityContext velocityContext = new VelocityContext();
velocityContext.put("","") // put your template values here
StringWriter writer = new StringWriter();
t.merge(this.velocityContext, writer);
System.out.println(writer.toString()); // print the updated template as string
For OSGI plugging code snippets.
final String TEMPLATE = "resources/template.vm" // located in the resources folder
Thread current = Thread.currentThread();
ClassLoader oldLoader = current.getContextClassLoader();
try {
current.setContextClassLoader(TemplateHelper.class.getClassLoader()); // TemplateHelper is a class inside your jar file
Properties p = new Properties();
p.setProperty("resource.loader", "class");
p.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
Velocity.init( p );
VelocityEngine ve = new VelocityEngine();
Template template = Velocity.getTemplate( TEMPLATE );
VelocityContext context = new VelocityContext();
context.put("tc", obj);

template.merge( context, writer );
return writer.toString() ;
} catch(Exception e){

If you're simply sharing a counter, consider using an AtomicInteger or another suitable class from the java.util.concurrent.atomic package:
public class Test {
private final static AtomicInteger count = new AtomicInteger(0);
public void foo() {
count.incrementAndGet();
}
}
I found the GeoCoder javascript a little buggy when I included it in my jsp files.
You can also try this:
var lat = "43.7667855" ;
var long = "-79.2157321" ;
var url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="
+lat+","+long+"&sensor=false";
$.get(url).success(function(data) {
var loc1 = data.results[0];
var county, city;
$.each(loc1, function(k1,v1) {
if (k1 == "address_components") {
for (var i = 0; i < v1.length; i++) {
for (k2 in v1[i]) {
if (k2 == "types") {
var types = v1[i][k2];
if (types[0] =="sublocality_level_1") {
county = v1[i].long_name;
//alert ("county: " + county);
}
if (types[0] =="locality") {
city = v1[i].long_name;
//alert ("city: " + city);
}
}
}
}
}
});
$('#city').html(city);
});
Non-python data is best bundled inside your Python modules using the package_data
support in setuptools. One thing I strongly recommend is using namespace packages to create shared namespaces which multiple projects can use -- much like the Java convention of putting packages in com.yourcompany.yourproject
(and being able to have a shared com.yourcompany.utils
namespace).
Re branching and merging, if you use a good enough source control system it will handle merges even through renames; Bazaar is particularly good at this.
Contrary to some other answers here, I'm +1 on having a src
directory top-level (with doc
and test
directories alongside). Specific conventions for documentation directory trees will vary depending on what you're using; Sphinx, for instance, has its own conventions which its quickstart tool supports.
Please, please leverage setuptools and pkg_resources; this makes it much easier for other projects to rely on specific versions of your code (and for multiple versions to be simultaneously installed with different non-code files, if you're using package_data
).
if you don't want to deactivate or activate the already installed venv just ensure you have set the pythonpath set
set pythonpath=C:\software\venv\include;C:\software\venv\lib;C:\software\venv\scripts;C:\software\venv\tcl;C:\software\venv\Lib\site-packages;
and then execute
"%pythonpath%" %venvpath%Scripts\mytestsite\manage.py runserver "%ipaddress%":8000
If you have Java 5, use char c = ...; String s = String.format ("\\u%04x", (int)c);
If your source isn't a Unicode character (char
) but a String, you must use charAt(index)
to get the Unicode character at position index
.
Don't use codePointAt(index)
because that will return 24bit values (full Unicode) which can't be represented with just 4 hex digits (it needs 6). See the docs for an explanation.
[EDIT] To make it clear: This answer doesn't use Unicode but the method which Java uses to represent Unicode characters (i.e. surrogate pairs) since char is 16bit and Unicode is 24bit. The question should be: "How can I convert char
to a 4-digit hex number", since it's not (really) about Unicode.
I had the same problem, finally I decide to kill service process.
for it try below steps:
get process id of service with
sc queryex <service name>
kill process with
taskkill /F /PID <Service PID>
Javascript has an eval()
function for such occasions:
function (varString) {
var myVar = eval(varString);
// .....
}
Edit: Sorry, I think I skimmed the question too quickly. This will only get you the variable, to set it you need
function SetTo5(varString) {
var newValue = 5;
eval(varString + " = " + newValue);
}
or if using a string:
function SetToString(varString) {
var newValue = "string";
eval(varString + " = " + "'" + newValue + "'");
}
But I imagine there is a more appropriate way to accomplish what you're looking for? I don't think eval() is something you really want to use unless there's a great reason for it. eval()
You can write your own generator. The secret key is essentially a byte array. Make sure that the string that you convert to a byte array is base64 encoded.
In Java, you could do something like this.
String key = "random_secret_key";
String base64Key = DatatypeConverter.printBase64Binary(key.getBytes());
byte[] secretBytes = DatatypeConverter.parseBase64Binary(base64Key);
Alternatively, with MTCNN and OpenCV(other dependencies including TensorFlow also required), you can:
1 Perform face detection(Input an image, output all boxes of detected faces):
from mtcnn.mtcnn import MTCNN
import cv2
face_detector = MTCNN()
img = cv2.imread("Anthony_Hopkins_0001.jpg")
detect_boxes = face_detector.detect_faces(img)
print(detect_boxes)
[{'box': [73, 69, 98, 123], 'confidence': 0.9996458292007446, 'keypoints': {'left_eye': (102, 116), 'right_eye': (150, 114), 'nose': (129, 142), 'mouth_left': (112, 168), 'mouth_right': (146, 167)}}]
2 save all detected faces to separate files:
for i in range(len(detect_boxes)):
box = detect_boxes[i]["box"]
face_img = img[box[1]:(box[1] + box[3]), box[0]:(box[0] + box[2])]
cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)
3 or Draw rectangles of all detected faces:
for box in detect_boxes:
box = box["box"]
pt1 = (box[0], box[1]) # top left
pt2 = (box[0] + box[2], box[1] + box[3]) # bottom right
cv2.rectangle(img, pt1, pt2, (0,255,0), 2)
cv2.imwrite("detected-boxes.jpg", img)
There is a library called BoofCV which claims to better than ZBar and other libraries.
Here are the steps to use that (any OS).
Pre-requisites:
pip install pyboof
Class to decode:
import os
import numpy as np
import pyboof as pb
pb.init_memmap() #Optional
class QR_Extractor:
# Src: github.com/lessthanoptimal/PyBoof/blob/master/examples/qrcode_detect.py
def __init__(self):
self.detector = pb.FactoryFiducial(np.uint8).qrcode()
def extract(self, img_path):
if not os.path.isfile(img_path):
print('File not found:', img_path)
return None
image = pb.load_single_band(img_path, np.uint8)
self.detector.detect(image)
qr_codes = []
for qr in self.detector.detections:
qr_codes.append({
'text': qr.message,
'points': qr.bounds.convert_tuple()
})
return qr_codes
Usage:
qr_scanner = QR_Extractor()
output = qr_scanner.extract('Your-Image.jpg')
print(output)

Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:
ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);
Using Node Version Manager (NVM):
Install it:
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
Test your installation:
close your current terminal, open a new terminal, and run:
command -v nvm
Use it to install as many versions as u like:
nvm install 8 # Install nodejs 8
nvm install --lts # Install latest LTS (Long Term Support) version
List installed versions:
nvm ls
Use a specific version:
nvm use 8 # Use this version on this shell
Set defaults:
nvm alias default 8 # Default to nodejs 8 on this shell
nvm alias default node # always use latest available as default nodejs for all shells
If your query has any JOINs, Mysql Workbench will not allow you to alter the table, even if your results are all from a single table.
For example, the following query
SELECT u.* FROM users u JOIN passwords p ON u.id=p.user_id WHERE p.password IS NULL;
will not allow you to edit the results or add rows, even though the results are limited to one table. You must specifically do something like:
SELECT * FROM users WHERE id=1012;
and then you can edit the row and add rows to the table.
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_

.Resizable(x => x.Columns(true))
.Sortable()
.Filterable()
.DataSource(dataSource => dataSource
.Ajax()

The only thing that assisted me was to set margin:0px

This again wasn't the most appealing way to solve the issue, but as it is only in one place I put it inline.
As an fyi the container-fluid and apparent bootstrap fixes only introduced an increased whitespace on either side of the visible page... :( Although I came across my solution by reading through the back and forth on the github issue - so worthwhile reading.
Declare a SecondActivity variable in FirstActivity
Like this
public class FirstActivity extends Activity {
SecondActivity secactivity;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main2);
}
public void method() {
// some code
secactivity.call_method();// 'Method' is Name of the any one method in SecondActivity
}
}
Using this format you can call any method from one activity to another.
We solved our Linux/php hook to SQL Server problem by creating a new login account with SQL Server authentication instead of Windows authentication.
In addition to max, you can also sort:
>>> lis
[(101, 153), (255, 827), (361, 961)]
>>> sorted(lis,key=lambda x: x[1], reverse=True)[0]
(361, 961)
Just adding some extra sorting if needed
=QUERY(A2:A,"select A, count(A) where A is not null group by A order by count(A) DESC label A 'Name', count(A) 'Count'",-1)
For what it's worth, I got inspired by the other answers and wrote a small utility which calls the platform specific APIs to be used universally from either Node.js or a browser:
/**
* Encode a string of text as base64
*
* @param data The string of text.
* @returns The base64 encoded string.
*/
function encodeBase64(data: string) {
if (typeof btoa === "function") {
return btoa(data);
} else if (typeof Buffer === "function") {
return Buffer.from(data, "utf-8").toString("base64");
} else {
throw new Error("Failed to determine the platform specific encoder");
}
}
/**
* Decode a string of base64 as text
*
* @param data The string of base64 encoded text
* @returns The decoded text.
*/
function decodeBase64(data: string) {
if (typeof atob === "function") {
return atob(data);
} else if (typeof Buffer === "function") {
return Buffer.from(data, "base64").toString("utf-8");
} else {
throw new Error("Failed to determine the platform specific decoder");
}
}

I had the same issue and found this question. However from the answers here I was not able to solve my problem. I started debugging the cpython code and thought that I might be discovered a bug. Therefore I opened a issue on the python issue tracker.
My mistake was that I did not understand that Py_SetPath
clears all inferred paths.
So one needs to set all paths when calling this function.
For completion I also copied the most important part of the conversation below.
My original issue text
I compiled the source of CPython 3.7.3 myself on Windows with Visual Studio 2017 together with some packages like e.g numpy. When I start the Python Interpreter I am able to import and use numpy. However when I am running the same script via the C-API I get an ModuleNotFoundError
.
So the first thing I did, was to check if numpy is in my site-packages directory and indeed there is a folder named numpy-1.16.2-py3.7-win-amd64.egg. (Makes sense because the python interpreter can find numpy)
The next thing I did was to get some information about the sys.path variable created when running the script via the C-API.
#### sys.path content ####
C:\Work\build\product\python37.zip
C:\Work\build\product\DLLs
C:\Work\build\product\lib
C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO\2017\PROFESSIONAL\COMMON7\IDE\EXTENSIONS\TESTPLATFORM
C:\Users\rvq\AppData\Roaming\Python\Python37\site-packages
Examining the content of sys.path I noticed two things.
C:\Work\build\product\python37.zip
has the correct path 'C:\Work\build\product\'
. There was just no zip file. All my files and directory were unpacked. So I zipped the files to an archive named python37.zip and this resolved the import error.
C:\Users\rvq\AppData\Roaming\Python\Python37\site-packages
is wrong it should be C:\Work\build\product\Lib\site-packages
but I dont know how this wrong path is created.
The next thing I tried was to use Py_SetPath(L"C:/Work/build/product/Lib/site-packages")
before calling Py_Initialize()
. This led to
Fatal Python Error 'unable to load the file system encoding' ModuleNotFoundError: No module named 'encodings'
I created a minimal c++ project with exact these two calls and started to debug Cpython.
int main()
{
Py_SetPath(L"C:/Work/build/product/Lib/site-packages");
Py_Initialize();
}
I tracked the call of Py_Initialize()
down to the call of
static int
zipimport_zipimporter___init___impl(ZipImporter *self, PyObject *path)
inside of zipimport.c
The comment above this function states the following:
Create a new zipimporter instance. 'archivepath' must be a path-like object to a zipfile, or to a specific path inside a zipfile. For example, it can be '/tmp/myimport.zip', or '/tmp/myimport.zip/mydirectory', if mydirectory is a valid directory inside the archive. 'ZipImportError' is raised if 'archivepath' doesn't point to a valid Zip archive. The 'archive' attribute of the zipimporter object contains the name of the zipfile targeted.
So for me it seems that the C-API expects the path set with Py_SetPath to be a path to a zipfile. Is this expected behaviour or is it a bug? If it is not a bug is there a way to changes this so that it can also detect directories?
PS: The ModuleNotFoundError did not occur for me when using Python 3.5.2+, which was the version I used in my project before. I also checked if I had set any PYTHONHOME or PYTHONPATH environment variables but I did not see one of them on my system.
Answer
This is probably a documentation failure more than anything else. We're in the middle of redesigning initialization though, so it's good timing to contribute this feedback.
The short answer is that you need to make sure Python can find the Lib/encodings
directory, typically by putting the standard library in sys.path
. Py_SetPath
clears all inferred paths, so you need to specify all the places Python should look. (The rules for where Python looks automatically are complicated and vary by platform, which is something I'm keen to fix.)
Paths that don't exist are okay, and that's the zip file. You can choose to put the stdlib into a zip, and it will be found automatically if you name it the default path, but you can also leave it unzipped and reference the directory.
A full walk through on embedding is more than I'm prepared to type on my phone. Hopefully that's enough to get you going for now.

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.
They should be
server {

server_name www.domain1.com;
root /var/www/domain1;
}
server {
listen 80;
server_name www.domain2.com;
root /var/www/domain2;

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.
when you do UNIQUE
as a table level constraint as you have done then what your defining is a bit like a composite primary key see ddl constraints, here is an extract
"This specifies that the *combination* of values in the indicated columns is unique across the whole table, though any one of the columns need not be (and ordinarily isn't) unique."
this means that either field could possibly have a non unique value provided the combination is unique and this does not match your foreign key constraint.
most likely you want the constraint to be at column level. so rather then define them as table level constraints, 'append' UNIQUE
to the end of the column definition like name VARCHAR(60) NOT NULL UNIQUE
or specify indivdual table level constraints for each field.
Note that GCC has an extension to the designated initializer notation which is very useful for the context. It is also allowed by clang
without comment (in part because it tries to be compatible with GCC).
The extension notation allows you to use ...
to designate a range of elements to be initialized with the following value. For example:
#include <stdio.h>
enum { ROW = 5, COLUMN = 10 };
int array[ROW][COLUMN] = { [0 ... ROW-1] = { [0 ... COLUMN-1] = 1 } };
int main(void)
{
for (int i = 0; i < ROW; i++)
{
for (int j = 0; j < COLUMN; j++)
printf("%2d", array[i][j]);
putchar('\n');
}
return 0;
}
The output is, unsurprisingly:
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
Note that Fortran 66 (Fortran IV) had repeat counts for initializers for arrays; it's always struck me as odd that C didn't get them when designated initializers were added to the language. And Pascal uses the 0..9
notation to designate the range from 0 to 9 inclusive, but C doesn't use ..
as a token, so it is not surprising that was not used.
Note that the spaces around the ...
notation are essentially mandatory; if they're attached to numbers, then the number is interpreted as a floating point number. For example, 0...9
would be tokenized as 0.
, .
, .9
, and floating point numbers aren't allowed as array subscripts.
With the named constants, ...ROW-1
would not cause trouble, but it is better to get into the safe habits.
Addenda:
I note in passing that GCC 7.3.0 rejects:
int array[ROW][COLUMN] = { [0 ... ROW-1] = { [0 ... COLUMN-1] = { 1 } } };
where there's an extra set of braces around the scalar initializer 1
(error: braces around scalar initializer [-Werror]
). I'm not sure that's correct given that you can normally specify braces around a scalar in int a = { 1 };
, which is explicitly allowed by the standard. I'm not certain it's incorrect, either.
I also wonder if a better notation would be [0]...[9]
— that is unambiguous, cannot be confused with any other valid syntax, and avoids confusion with floating point numbers.
int array[ROW][COLUMN] = { [0]...[4] = { [0]...[9] = 1 } };
Maybe the standards committee would consider that?

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install yarn

This is a question with a simple answer and a long-winded answer.
The simple answer is the heap. Classes and all of the data applying to classes (not instance data) is stored in the Permanent Generation section of the heap.
The long answer is already on stack overflow:
There is a thorough description of memory and garbage collection in the JVM as well as an answer that talks more concisely about it.
You can combine multiple selectors with a comma:
$('#Create .myClass,#Edit .myClass').plugin({options here});
Or if you're going to have a bunch of them, you could add a class to all your form elements and then search within that class. This doesn't get you the supposed speed savings of restricting the search, but I honestly wouldn't worry too much about that if I were you. Browsers do a lot of fancy things to optimize common operations behind your back -- the simple class selector might be faster.
Follow @reVerse answer but in my case, I already had some property in my AppTheme
like
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:textColor">#111</item>
<item name="android:textSize">13sp</item>
</style>
I solved it by
1) Change the import from android.app.AlertDialog
to
android.support.v7.app.AlertDialog
2) I override 2 property in AppTheme
with null value
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#FFC107</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#4CAF50</item>
<item name="android:textColor">@null</item>
<item name="android:textSize">@null</item>
</style>
.
AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.MyAlertDialogStyle);
Hope it help another people
The solution that really works turned out to be setting simple error handler with E_WARNING
parameter, like so:
set_error_handler("warning_handler", E_WARNING);
dns_get_record(...)
restore_error_handler();
function warning_handler($errno, $errstr) {
// do something
}
Use urlparse
to get just the path and then split the path you get from it on /
characters:
from urllib.parse import urlparse
my_url = "http://example.com/some/path/last?somequery=param"
last_path_fragment = urlparse(my_url).path.split('/')[-1] # returns 'last'
Note: if your url ends with a /
character, the above will return ''
(i.e. the empty string). If you want to handle that case differently, you need to strip the trailing /
character before you split the path:
my_url = "http://example.com/last/"
# handle URL ending in `/` by removing it.
last_path_fragment = urlparse(my_url).path.rstrip('/').split('/')[-1] # returns 'last'
Further reading for any of the topics here: The Definitive Guide to Linux System Calls
I verified these using GNU Assembler (gas) on Linux.
x86-32 aka i386 Linux System Call convention:
In x86-32 parameters for Linux system call are passed using registers. %eax
for syscall_number. %ebx, %ecx, %edx, %esi, %edi, %ebp are used for passing 6 parameters to system calls.
The return value is in %eax
. All other registers (including EFLAGS) are preserved across the int $0x80
.
I took following snippet from the Linux Assembly Tutorial but I'm doubtful about this. If any one can show an example, it would be great.
If there are more than six arguments,
%ebx
must contain the memory location where the list of arguments is stored - but don't worry about this because it's unlikely that you'll use a syscall with more than six arguments.
For an example and a little more reading, refer to http://www.int80h.org/bsdasm/#alternate-calling-convention. Another example of a Hello World for i386 Linux using int 0x80
: Hello, world in assembly language with Linux system calls?
There is a faster way to make 32-bit system calls: using sysenter
. The kernel maps a page of memory into every process (the vDSO), with the user-space side of the sysenter
dance, which has to cooperate with the kernel for it to be able to find the return address. Arg to register mapping is the same as for int $0x80
. You should normally call into the vDSO instead of using sysenter
directly. (See The Definitive Guide to Linux System Calls for info on linking and calling into the vDSO, and for more info on sysenter
, and everything else to do with system calls.)
x86-32 [Free|Open|Net|DragonFly]BSD UNIX System Call convention:
Parameters are passed on the stack. Push the parameters (last parameter pushed first) on to the stack. Then push an additional 32-bit of dummy data (Its not actually dummy data. refer to following link for more info) and then give a system call instruction int $0x80
http://www.int80h.org/bsdasm/#default-calling-convention
(Note: x86-64 Mac OS X is similar but different from Linux. TODO: check what *BSD does)
Refer to section: "A.2 AMD64 Linux Kernel Conventions" of System V Application Binary Interface AMD64 Architecture Processor Supplement. The latest versions of the i386 and x86-64 System V psABIs can be found linked from this page in the ABI maintainer's repo. (See also the x86 tag wiki for up-to-date ABI links and lots of other good stuff about x86 asm.)
Here is the snippet from this section:
- User-level applications use as integer registers for passing the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9. The kernel interface uses %rdi, %rsi, %rdx, %r10, %r8 and %r9.
- A system-call is done via the
syscall
instruction. This clobbers %rcx and %r11 as well as the %rax return value, but other registers are preserved.- The number of the syscall has to be passed in register %rax.
- System-calls are limited to six arguments, no argument is passed directly on the stack.
- Returning from the syscall, register %rax contains the result of the system-call. A value in the range between -4095 and -1 indicates an error, it is
-errno
.- Only values of class INTEGER or class MEMORY are passed to the kernel.
Remember this is from the Linux-specific appendix to the ABI, and even for Linux it's informative not normative. (But it is in fact accurate.)
This 32-bit int $0x80
ABI is usable in 64-bit code (but highly not recommended). What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code? It still truncates its inputs to 32-bit, so it's unsuitable for pointers, and it zeros r8-r11.
x86-32 Function Calling convention:
In x86-32 parameters were passed on stack. Last parameter was pushed first on to the stack until all parameters are done and then call
instruction was executed. This is used for calling C library (libc) functions on Linux from assembly.
Modern versions of the i386 System V ABI (used on Linux) require 16-byte alignment of %esp
before a call
, like the x86-64 System V ABI has always required. Callees are allowed to assume that and use SSE 16-byte loads/stores that fault on unaligned. But historically, Linux only required 4-byte stack alignment, so it took extra work to reserve naturally-aligned space even for an 8-byte double
or something.
Some other modern 32-bit systems still don't require more than 4 byte stack alignment.
x86-64 System V passes args in registers, which is more efficient than i386 System V's stack args convention. It avoids the latency and extra instructions of storing args to memory (cache) and then loading them back again in the callee. This works well because there are more registers available, and is better for modern high-performance CPUs where latency and out-of-order execution matter. (The i386 ABI is very old).
In this new mechanism: First the parameters are divided into classes. The class of each parameter determines the manner in which it is passed to the called function.
For complete information refer to : "3.2 Function Calling Sequence" of System V Application Binary Interface AMD64 Architecture Processor Supplement which reads, in part:
Once arguments are classified, the registers get assigned (in left-to-right order) for passing as follows:
- If the class is MEMORY, pass the argument on the stack.
- If the class is INTEGER, the next available register of the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9 is used
So %rdi, %rsi, %rdx, %rcx, %r8 and %r9
are the registers in order used to pass integer/pointer (i.e. INTEGER class) parameters to any libc function from assembly. %rdi is used for the first INTEGER parameter. %rsi for 2nd, %rdx for 3rd and so on. Then call
instruction should be given. The stack (%rsp
) must be 16B-aligned when call
executes.
If there are more than 6 INTEGER parameters, the 7th INTEGER parameter and later are passed on the stack. (Caller pops, same as x86-32.)
The first 8 floating point args are passed in %xmm0-7, later on the stack. There are no call-preserved vector registers. (A function with a mix of FP and integer arguments can have more than 8 total register arguments.)
Variadic functions (like printf
) always need %al
= the number of FP register args.
There are rules for when to pack structs into registers (rdx:rax
on return) vs. in memory. See the ABI for details, and check compiler output to make sure your code agrees with compilers about how something should be passed/returned.
Note that the Windows x64 function calling convention has multiple significant differences from x86-64 System V, like shadow space that must be reserved by the caller (instead of a red-zone), and call-preserved xmm6-xmm15. And very different rules for which arg goes in which register.
Looks like you are out of stack memory. You may want to increase it as Davide stated. To do it in python code, you would need to run your "main()" using threading:
def main():
pass # write your code here
sys.setrecursionlimit(2097152) # adjust numbers
threading.stack_size(134217728) # for your needs
main_thread = threading.Thread(target=main)
main_thread.start()
main_thread.join()

Add a Console.ReadKey
call to your program to force it to wait for you to press a key before exiting.
To answer your first question: yes, if the file is not there Python will create it.
Secondly, the user (yourself) running the python script doesn't have write privileges to create a file in the directory.
Note that Internet Explorer from version 5 up to 8 will throw an error when trying to download a file served via https and the server sending Cache-Control: no-cache
or Pragma: no-cache
headers.
See http://support.microsoft.com/kb/812935/en-us
The use of Cache-Control: no-store
and Pragma: private
seems to be the closest thing which still works.
What for? You need to clarify: Do you need a pointer to the first element of an array, or an array?
If you're calling an API function that expects the former, you can do do_something(&v[0], v.size())
, where v
is a vector of double
s. The elements of a vector are contiguous.
Otherwise, you just have to copy each element:
double arr[100];
std::copy(v.begin(), v.end(), arr);
Ensure not only thar arr
is big enough, but that arr
gets filled up, or you have uninitialized values.
Ternary operator should do nicely here: condition ? first_expression : second_expression;
strLevel = !Convert.IsDBNull(rsData["usr.ursrdaystime"]) ? Convert.ToString(rsData["usr.ursrdaystime"]) : null
Once you set your Global Jenkins credentials, you can apply this step:
stage('Update GIT') {
steps {
script {
catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE') {
withCredentials([usernamePassword(credentialsId: 'example-secure', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
def encodedPassword = URLEncoder.encode("$GIT_PASSWORD",'UTF-8')
sh "git config user.email [email protected]"
sh "git config user.name example"
sh "git add ."
sh "git commit -m 'Triggered Build: ${env.BUILD_NUMBER}'"
sh "git push https://${GIT_USERNAME}:${encodedPassword}@github.com/${GIT_USERNAME}/example.git"
}
}
}
}
}
By using the the unpacking operator:
>>> def tostr(**kwargs):
return kwargs
>>> var = {}
>>> something_else = 3
>>> tostr(var = var,something_else=something_else)
{'var' = {},'something_else'=3}
You can use the below code to submit the form using JavaScript:
document.getElementById('FormID').submit();
You can use fork() to detach your script from the tty and have it continue to run, like so:
import os, sys
fpid = os.fork()
if fpid!=0:
# Running as daemon now. PID is fpid
sys.exit(0)
Of course you also need to implement an endless loop, like
while 1:
do_your_check()
sleep(5)
Hope this get's you started.
Check out Quartz.NET. You can use it within a Windows service. It allows you to run a job based on a configured schedule, and it even supports a simple "cron job" syntax. I've had a lot of success with it.
Here's a quick example of its usage:
// Instantiate the Quartz.NET scheduler
var schedulerFactory = new StdSchedulerFactory();
var scheduler = schedulerFactory.GetScheduler();
// Instantiate the JobDetail object passing in the type of your
// custom job class. Your class merely needs to implement a simple
// interface with a single method called "Execute".
var job = new JobDetail("job1", "group1", typeof(MyJobClass));
// Instantiate a trigger using the basic cron syntax.
// This tells it to run at 1AM every Monday - Friday.
var trigger = new CronTrigger(
"trigger1", "group1", "job1", "group1", "0 0 1 ? * MON-FRI");
// Add the job to the scheduler
scheduler.AddJob(job, true);
scheduler.ScheduleJob(trigger);
Here's a plain JavaScript version:
function scroll(e) {
var delta = (e.type === "mousewheel") ? e.wheelDelta : e.detail * -40;
if (delta < 0 && (this.scrollHeight - this.offsetHeight - this.scrollTop) <= 0) {
this.scrollTop = this.scrollHeight;
e.preventDefault();
} else if (delta > 0 && delta > this.scrollTop) {
this.scrollTop = 0;
e.preventDefault();
}
}
document.querySelectorAll(".scroller").addEventListener("mousewheel", scroll);
document.querySelectorAll(".scroller").addEventListener("DOMMouseScroll", scroll);
Rom, you're doing it wrong. You don't want to write files to disk so that IIS can serve them up. That adds security implications as well as increases complexity. All you really need to do is save the CSV directly to the response stream.
Here's the scenario: User wishes to download csv. User submits a form with details about the csv they want. You prepare the csv, then provide the user a URL to an aspx page which can be used to construct the csv file and write it to the response stream. The user clicks the link. The aspx page is blank; in the page codebehind you simply write the csv to the response stream and end it.
You can add the following to the (I believe this is correct) Load event:
string attachment = "attachment; filename=MyCsvLol.csv";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "text/csv";
HttpContext.Current.Response.AddHeader("Pragma", "public");
var sb = new StringBuilder();
foreach(var line in DataToExportToCSV)
sb.AppendLine(TransformDataLineIntoCsv(line));
HttpContext.Current.Response.Write(sb.ToString());
writing to the response stream code ganked from here.
You are searching for a multimap, and indeed both commons-collections and Guava have several implementations for that. Multimaps allow for multiple keys by maintaining a collection of values per key, i.e. you can put a single object into the map, but you retrieve a collection.
If you can use Java 5, I would prefer Guava's Multimap
as it is generics-aware.
As @Psyonity mentioned, you can use the conditionalWeakTable to add properties to existing objects. Combined with the dynamic ExpandoObject, you could implement dynamic extension properties in a few lines:
using System.Dynamic;
using System.Runtime.CompilerServices;
namespace ExtensionProperties
{
/// <summary>
/// Dynamically associates properies to a random object instance
/// </summary>
/// <example>
/// var jan = new Person("Jan");
///
/// jan.Age = 24; // regular property of the person object;
/// jan.DynamicProperties().NumberOfDrinkingBuddies = 27; // not originally scoped to the person object;
///
/// if (jan.Age < jan.DynamicProperties().NumberOfDrinkingBuddies)
/// Console.WriteLine("Jan drinks too much");
/// </example>
/// <remarks>
/// If you get 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create' you should reference Microsoft.CSharp
/// </remarks>
public static class ObjectExtensions
{
///<summary>Stores extended data for objects</summary>
private static ConditionalWeakTable<object, object> extendedData = new ConditionalWeakTable<object, object>();
/// <summary>
/// Gets a dynamic collection of properties associated with an object instance,
/// with a lifetime scoped to the lifetime of the object
/// </summary>
/// <param name="obj">The object the properties are associated with</param>
/// <returns>A dynamic collection of properties associated with an object instance.</returns>
public static dynamic DynamicProperties(this object obj) => extendedData.GetValue(obj, _ => new ExpandoObject());
}
}
A usage example is in the xml comments:
var jan = new Person("Jan");
jan.Age = 24; // regular property of the person object;
jan.DynamicProperties().NumberOfDrinkingBuddies = 27; // not originally scoped to the person object;
if (jan.Age < jan.DynamicProperties().NumberOfDrinkingBuddies)
{
Console.WriteLine("Jan drinks too much");
}
jan = null; // NumberOfDrinkingBuddies will also be erased during garbage collection
I dont know why you havent marked on of these gr8 answers... here is another option which would enable you and anyone else visiting to control transition speed and pause time
JAVASCRIPT
$(function () {
/* SET PARAMETERS */
var change_img_time = 5000;
var transition_speed = 100;
var simple_slideshow = $("#exampleSlider"),

listLen = listItems.length,
i = 0,
changeList = function () {
listItems.eq(i).fadeOut(transition_speed, function () {
i += 1;
if (i === listLen) {
i = 0;
}
listItems.eq(i).fadeIn(transition_speed);
});
};
listItems.not(':first').hide();
setInterval(changeList, change_img_time);
});
.

In the picture you can see. In the set script options, choose the last option: Types of data to script you click at the right side and you choose what you want. This is the option you should choose to export a schema and data
You can use
string wanted_path = Path.GetDirectoryName(Path.GetDirectoryName(System.IO.Directory.GetCurrentDirectory()));
Another solution is:

Probably an archaic answer, but functional.
Way later but still worth mentioning is that you can also use variables to output values in the SET clause of an UPDATE or in the fields of a SELECT;
DECLARE @val1 int;
DECLARE @val2 int;
UPDATE [dbo].[PortalCounters_TEST]
SET @val1 = NextNum, @val2 = NextNum = NextNum + 1
WHERE [Condition] = 'unique value'
SELECT @val1, @val2
In the example above @val1 has the before value and @val2 has the after value although I suspect any changes from a trigger would not be in val2 so you'd have to go with the output table in that case. For anything but the simplest case, I think the output table will be more readable in your code as well.
One place this is very helpful is if you want to turn a column into a comma-separated list;
DECLARE @list varchar(max) = '';
DECLARE @comma varchar(2) = '';
SELECT @list = @list + @comma + County, @comma = ', ' FROM County
print @list
Images can be placed in place of radio buttons by using label and span elements.
<div class="customize-radio">
<label>Favourite Smiley</label><br>
<label for="hahaha">
<input type="radio" name="smiley" id="hahaha">
<span class="haha-img"></span>
HAHAHA
</label>
<label for="kiss">
<input type="radio" name="smiley" id="kiss">
<span class="kiss-img"></span>
Kiss
</label>
<label for="tongueOut">
<input type="radio" name="smiley" id="tongueOut">
<span class="tongueout-img"></span>
TongueOut
</label>
</div>
Radio button should be hidden,
.customize-radio label > input[type = 'radio'] {
visibility: hidden;
position: absolute;
}
Image can be given in the span tag,
.customize-radio label > input[type = 'radio'] ~ span{
cursor: pointer;
width: 27px;
height: 24px;
display: inline-block;
background-size: 27px 24px;
background-repeat: no-repeat;
}
.haha-img {
background-image: url('hahabefore.png');
}
.kiss-img{
background-image: url('kissbefore.png');
}
.tongueout-img{
background-image: url('tongueoutbefore.png');
}
To change the image on click of radio button, add checked state to the input tag,
.customize-radio label > input[type = 'radio']:checked ~ span.haha-img{
background-image: url('haha.png');
}
.customize-radio label > input[type = 'radio']:checked ~ span.kiss-img{
background-image: url('kiss.png');
}
.customize-radio label > input[type = 'radio']:checked ~ span.tongueout-img{
background-image: url('tongueout.png');
}
If you have any queries, Refer to the following link, As I have taken solution from the below blog, http://frontendsupport.blogspot.com/2018/06/cool-radio-buttons-with-images.html
Environment variables must be strings, so use
os.environ["DEBUSSY"] = "1"
to set the variable DEBUSSY
to the string 1
.
To access this variable later, simply use:
print(os.environ["DEBUSSY"])
Child processes automatically inherit the environment variables of the parent process -- no special action on your part is required.
Your CSS is actually setting the rest of the document to not show overflow therefore the document itself isn't scrolling. The easiest fix for this is bind the event to the thing that is scrolling, which in your case is div#page
.
So its easy as changing:
$(document).scroll(function() { // OR $(window).scroll(function() {
didScroll = true;
});
to
$('div#page').scroll(function() {
didScroll = true;
});
Because it's the size of an instance of the type - presumably enum values are stored as (32-bit / 4-byte) ints here.
This is my take at it. Combined from the answers and MSDN
public static TEnum ParseToEnum<TEnum>(this string text) where TEnum : struct, IConvertible, IComparable, IFormattable
{
if (string.IsNullOrEmpty(text) || !typeof(TEnum).IsEnum)
throw new ArgumentException("TEnum must be an Enum type");
try
{
var enumValue = (TEnum)Enum.Parse(typeof(TEnum), text.Trim(), true);
return enumValue;
}
catch (Exception)
{
throw new ArgumentException(string.Format("{0} is not a member of the {1} enumeration.", text, typeof(TEnum).Name));
}
}
You can do it with plain JavaScript:
alert('123-4-'.substr(0, 4)); // outputs "123-"
This returns the first four characters of your string (adjust 4
to suit your needs).
Select the folder containing the package tree of these classes, right-click and choose "Mark Directory as -> Source Root"

print(base64String)
Once you've dropped all the tables (and the indexes will disappear when the table goes) then there's nothing left in a SQLite database as far as I know, although the file doesn't seem to shrink (from a quick test I just did).
So deleting the file would seem to be fastest - it should just be recreated when your app tries to access the db file.
From 5.2.2/2 (character display semantics) :
\b
(backspace) Moves the active position to the previous position on the current line. If the active position is at the initial position of a line, the behavior of the display device is unspecified.
\n
(new line) Moves the active position to the initial position of the next line.
\r
(carriage return) Moves the active position to the initial position of the current line.
Here, your code produces :
<new_line>ab
\b
: back one charactersi
: overrides the b
with s
(producing asi
on the second line)\r
: back at the beginning of the current lineha
: overrides the first two characters (producing hai
on the second line)In the end, the output is :
\nhai
Make your action
empty. You don't need to set the onclick
attribute, that's only javascript. When you click your submit button, it will reload your page with input from the form. So write your PHP code at the top of the form.
<?php
if( isset($_GET['submit']) )
{
//be sure to validate and clean your variables
$val1 = htmlentities($_GET['val1']);
$val2 = htmlentities($_GET['val2']);
//then you can use them in a PHP function.
$result = myFunction($val1, $val2);
}
?>
<?php if( isset($result) ) echo $result; //print the result above the form ?>
<form action="" method="get">
Inserisci number1:
<input type="text" name="val1" id="val1"></input>
<?php echo "ciaoooo"; ?>
<br></br>
Inserisci number2:
<input type="text" name="val2" id="val2"></input>
<br></br>
<input type="submit" name="submit" value="send"></input>
</form>

I would recommend using DialogFragment
.
Sure, creating a "Yes/No" dialog with it is pretty complex considering that it should be rather simple task, but creating a similar dialog box with Dialog
is surprisingly complicated as well.
(Activity lifecycle makes it complicated - you must let Activity
manage the lifecycle of the dialog box - and there is no way to pass custom parameters e.g. the custom message to Activity.showDialog
if using API levels under 8)
The nice thing is that you can usually build your own abstraction on top of DialogFragment
pretty easily.
The last couple of answers are almost correct - I have tons of apps that generate messages that need to end up with different consumers so the process is very simple.
If you want multiple consumers to the same message, do the following procedure.
Create multiple queues, one for each app that is to receive the message, in each queue properties, "bind" a routing tag with the amq.direct exchange. Change you publishing app to send to amq.direct and use the routing-tag (not a queue). AMQP will then copy the message into each queue with the same binding. Works like a charm :)
Example: Lets say I have a JSON string I generate, I publish it to the "amq.direct" exchange using the routing tag "new-sales-order", I have a queue for my order_printer app that prints order, I have a queue for my billing system that will send a copy of the order and invoice the client and I have a web archive system where I archive orders for historic/compliance reasons and I have a client web interface where orders are tracked as other info comes in about an order.
So my queues are: order_printer, order_billing, order_archive and order_tracking All have the binding tag "new-sales-order" bound to them, all 4 will get the JSON data.
This is an ideal way to send data without the publishing app knowing or caring about the receiving apps.

What's worked for me recently is to remove all height=""
and width=""
attributes from the <svg>
tag and all child tags. Then you can use scaling using a percentage of the parent container's height or width.
Before:
<svg width="3212" height="3212" viewBox="0 0 3212 3212" fill="none" xmlns="http://www.w3.org/2000/svg">
circle cx="1606" cy="1606" r="1387" stroke="black" stroke-width="438"/>
</svg>
After:
<svg viewBox="0 0 3212 3212" fill="none" xmlns="http://www.w3.org/2000/svg">
circle cx="1606" cy="1606" r="1387" stroke="black" stroke-width="438"/>

This is new item in the language which I think we are going to be struggling with for years to come. The 'auto' of the start presents not only readability problem , from now on when you encounter it you will have to spend considerable time trying to figure out wtf it is(just like the time that intern named all variables xyz :)), but you also will spend considerable time cleaning after easily excitable programmers , like the once who replied before me. Example from above , I can bet $1000 , will be written "for (auto it : s)", not "for (auto& it : s)", as a result invoking move semantics where you list expecting it, modifying your collection underneath .
Another example of the problem is your question itself. You clearly don't know much about stl iterators and you trying to overcome that gap through usage of the magic of 'auto', as a result you create the code that might be problematic later on

All other answers don't quite solve the issue. They print the date formatted as mm/dd/yyyy but the question was regarding MM/dd/yyyy. Notice the subtle difference? MM indicates that a leading zero must pad the month if the month is a single digit, thus having it always be a double digit number.
i.e. whereas mm/dd would be 3/31, MM/dd would be 03/31.
I've created a simple function to achieve this. Notice that the same padding is applied not only to the month but also to the day of the month, which in fact makes this MM/DD/yyyy:
function getFormattedDate(date) {_x000D_
var year = date.getFullYear();_x000D_
_x000D_
var month = (1 + date.getMonth()).toString();_x000D_
month = month.length > 1 ? month : '0' + month;_x000D_
_x000D_
var day = date.getDate().toString();_x000D_
day = day.length > 1 ? day : '0' + day;_x000D_
_x000D_
return month + '/' + day + '/' + year;_x000D_
}
_x000D_
Update for ES2017 using String.padStart(), supported by all major browsers except IE.
function getFormattedDate(date) {_x000D_
let year = date.getFullYear();_x000D_
let month = (1 + date.getMonth()).toString().padStart(2, '0');_x000D_
let day = date.getDate().toString().padStart(2, '0');_x000D_
_x000D_
return month + '/' + day + '/' + year;_x000D_

I am using Idea based Android Studio (some people are talking about eclipse one here)
When I launch the app in the emulator (using the Run App button of Android Studio) AVD shows up but the app does not launch or run.
However when I connect my mobile and launch the app on my mobile the App works (this itself took some time, enabling developer options on mobile and doing the right configuration)
1 - I installed the app manually by dragging the APK file on AVD. (APK file is app\build\outputs\apk\debug folder)
2 - Then my AVD was not showing the installed APP list. 3 - I searched my APP using Google bar on AVD and dragged the APP icon on the home screen of AVD.
4 - I can now launch the APP using my APP icon on the home screen of AVD.
That's how I am working around my problem. I will try to debug more on why it does not get installed and launched directly.
I have verified that Run App Icon does install the Application. Installation, not launching, appears to be the problem for me.

You can use the xmp
element, see What was the <XMP> tag used for?. It has been in HTML since the beginning and is supported by all browsers. Specifications frown upon it, but HTML5 CR still describes it and requires browsers to support it (though it also tells authors not to use it, but it cannot really prevent you).
Everything inside xmp
is taken as such, no markup (tags or character references) is recognized there, except, for apparent reason, the end tag of the element itself, </xmp>
.
Otherwise xmp
is rendered like pre
.
When using “real XHTML”, i.e. XHTML served with an XML media type (which is rare), the special parsing rules do not apply, so xmp
is treated like pre
. But in “real XHTML”, you can use a CDATA section, which implies similar parsing rules. It has no special formatting, so you would probably want to wrap it inside a pre
element:
<pre><![CDATA[
This is a demo, tags like <p> will
appear literally.
]]></pre>
I don’t see how you could combine xmp
and CDATA section to achieve so-called polyglot markup
auto
was a keyword that C++ "inherited" from C that had been there nearly forever, but virtually never used because there were only two possible conditions: either it wasn't allowed, or else it was assumed by default.
The use of auto
to mean a deduced type was new with C++11.
At the same time, auto x = initializer
deduces the type of x
from the type of initializer
the same way as template type deduction works for function templates. Consider a function template like this:
template<class T>
int whatever(T t) {
// point A
};
At point A, a type has been assigned to T
based on the value passed for the parameter to whatever
. When you do auto x = initializer;
, the same type deduction is used to determine the type for x
from the type of initializer
that's used to initialize it.
This means that most of the type deduction mechanics a compiler needs to implement auto
were already present and used for templates on any compiler that even sort of attempted to implement C++98/03. As such, adding support for auto
was apparently fairly easy for essentially all the compiler teams--it was added quite quickly, and there seem to have been few bugs related to it either.
When this answer was originally written (in 2011, before the ink was dry on the C++ 11 standard) auto
was already quite portable. Nowadays, it's thoroughly portable among all the mainstream compilers. The only obvious reasons to avoid it would be if you need to write code that's compatible with a C compiler, or you have a specific need to target some niche compiler that you know doesn't support it (e.g., a few people still write code for MS-DOS using compilers from Borland, Watcom, etc., that haven't seen significant upgrades in decades). If you're using a reasonably current version of any of the mainstream compilers, there's no reason to avoid it at all though.
You can do this:
create type number_tab is table of number;
select * from table (number_tab(1,2,3,4,5,6));
The column is given the name COLUMN_VALUE by Oracle, so this works too:
select column_value from table (number_tab(1,2,3,4,5,6));
Sometimes explicitly stating your table column names (especially in an insert query) may help. For example, the query:
INSERT INTO tableName(param1, param2, param3) VALUES(?, ?, ?)
may work better as opposed to:
INSERT INTO tableName VALUES(?, ?, ?)
That's called SQL INJECTION. The '
tries to open/close a string in your mysql query. You should always escape any string that gets into your queries.
for example,
instead of this:
"VALUES ('$sender_id') "
do this:
"VALUES ('". mysql_real_escape_string($sender_id) ."') "
(or equivalent, of course)
However, it's better to automate this, using PDO, named parameters, prepared statements or many other ways. Research about this and SQL Injection (here you have some techniques).
Hope it helps. Cheers
git log --full-history -- your_file
will show you all commits in your repo's history, including merge commits, that touched your_file
. The last (top) one is the one that deleted the file.
The --full-history
flag here is important. Without it, Git performs "history simplification" when you ask it for the log of a file. The docs are light on details about exactly how this works and I lack the grit and courage required to try to figure it out from the source code, but the git-log docs have this much to say:
Default mode
Simplifies the history to the simplest history explaining the final state of the tree. Simplest because it prunes some side branches if the end result is the same (i.e. merging branches with the same content)
This is obviously concerning when the file whose history we want is deleted, since the simplest history explaining the final state of a deleted file is no history. Is there a risk that git log
without --full-history
will simply claim that the file was never created? Unfortunately, yes. Here's a demonstration:
mark@lunchbox:~/example$ git init

Notice how git log -- bar
in the terminal dump above resulted in literally no output; Git is "simplifying" history down into a fiction where bar
never existed. git log --full-history -- bar
, on the other hand, gives us the commit that created bar
and the commit that deleted it.
To be clear: this issue isn't merely theoretical. I only looked into the docs and discovered the --full-history
flag because git log -- some_file
was failing for me in a real repository where I was trying to track a deleted file down. History simplification might sometimes be helpful when you're trying to understand how a currently-existing file came to be in its current state, but when trying to track down a file deletion it's more likely to screw you over by hiding the commit you care about. Always use the --full-history
flag for this use case.
You can use this code line in view(form)
<?= $form->field($model, 'hidden1')->hiddenInput(['value'=>'your_value'])->label(false) ?>
Please refere this as example
If your need to pass currant date and time as hidden input : Model attribute is 'created_on' and its value is retrieve from date('Y-m-d H:i:s') , just like:"2020-03-10 09:00:00"
<?= $form->field($model, 'created_on')->hiddenInput(['value'=>date('Y-m-d H:i:s')])->label(false) ?>
To complete @thecatontheflat answer I would recommend to also wrap your action inside of a try … catch
block. This will prevent your JSON endpoint from breaking on exceptions. Here's the skeleton I use:
public function someAction()
{
try {
// Your logic here...
return new JsonResponse([
'success' => true,
'data' => [] // Your data here
]);
} catch (\Exception $exception) {
return new JsonResponse([
'success' => false,
'code' => $exception->getCode(),
'message' => $exception->getMessage(),
]);
}
}
This way your endpoint will behave consistently even in case of errors and you will be able to treat them right on a client side.
You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.
var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);
_x000D_
<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>
_x000D_
This should work, I just tested it out and it worked as expected: no expansion, substitution, or what-have-you took place.
cat <<< '
#!/bin/bash
curr=`cat /sys/class/backlight/intel_backlight/actual_brightness`
if [ $curr -lt 4477 ]; then
curr=$((curr+406));
echo $curr > /sys/class/backlight/intel_backlight/brightness;
fi' > file # use overwrite mode so that you don't keep on appending the same script to that file over and over again, unless that's what you want.
Using the following also works.
cat <<< ' > file
... code ...'
Also, it's worth noting that when using heredocs, such as << EOF
, substitution and variable expansion and the like takes place. So doing something like this:
cat << EOF > file
cd "$HOME"
echo "$PWD" # echo the current path
EOF
will always result in the expansion of the variables $HOME
and $PWD
. So if your home directory is /home/foobar
and the current path is /home/foobar/bin
, file
will look like this:
cd "/home/foobar"
echo "/home/foobar/bin"
instead of the expected:
cd "$HOME"
echo "$PWD"
protected: the variable or method will be available only to child classes (in any assembly)
protected internal: available to child classes in any assembly and to all the classes within the same assembly
Yes it should be possible, even if the site is from another domain.
For example, in an HTML page on my site I have an iFrame whose contents are sourced from another website. The iFrame content is a single select field.
I need to be able to read the selected value on my site. In other words, I need to use the select list from another domain inside my own application. I do not have control over any server settings.
Initially therefore we might be tempted to do something like this (simplified):
HTML in my site:
<iframe name='select_frame' src='http://www.othersite.com/select.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>
HTML contents of iFrame (loaded from select.php
on another domain):
<select id='select_name'>
<option value='john'>John</option>
<option value='jim' selected>Jim</option>
</select>
jQuery:
$('input:button[name=save]').click(function() {
var name = $('iframe[name=select_frame]').contents().find('#select_name').val();
});
However, I receive this javascript error when I attempt to read the value:
Blocked a frame with origin "http://www.myownsite.com" from accessing a frame with origin "http://www.othersite.com". Protocols, domains, and ports must match.
To get around this problem, it seems that you can indirectly source the iFrame from a script in your own site, and have that script read the contents from the other site using a method like file_get_contents()
or curl
etc.
So, create a script (for example: select_local.php
in the current directory) on your own site with contents similar to this:
PHP content of select_local.php:
<?php
$url = "http://www.othersite.com/select.php?" . $_SERVER['QUERY_STRING'];
$html_select = file_get_contents($url);
echo $html_select;
?>
Also modify the HTML to call this local (instead of the remote) script:
<iframe name='select_frame' src='select_local.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>
Now your browser should think that it is loading the iFrame content from the same domain.
In your particular case the issue seem to be with accessing the site from non-canonical url (www.site.com vs. site.com).
Instead of fixing CORS issue (which may require writing proxy to server fonts with proper CORS headers depending on service provider) you can normalize your Urls to always server content on canonical Url and simply redirect if one requests page without "www.".
Alternatively you can upload fonts to different server/CDN that is known to have CORS headers configured or you can easily do so.
Use the indent
argument of the dumps
function in the json module.
From the docs:
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
I just recently needed to do this for two separate repositories that share a common history. I started with:
Org/repository1 master
Org/repository2 master
I wanted all the changes from repository2 master
to be applied to repository1 master
, accepting all changes that repository2 would make. In git's terms, this should be a strategy called -s theirs
BUT it does not exist. Be careful because -X theirs
is named like it would be what you want, but it is NOT the same (it even says so in the man page).
The way I solved this was to go to repository2
and make a new branch repo1-merge
. In that branch, I ran git pull [email protected]:Org/repository1 -s ours
and it merges fine with no issues. I then push it to the remote.
Then I go back to repository1
and make a new branch repo2-merge
. In that branch, I run git pull [email protected]:Org/repository2 repo1-merge
which will complete with issues.
Finally, you would either need to issue a merge request in repository1
to make it the new master, or just keep it as a branch.
try:
SELECT * FROM service s WHERE s.service_id = ?;
IF @@ROWCOUNT=0
BEGIN
PRINT 'no rows!'
END
Give them a trivial pom with these jars listed as dependencies and instructions to run:
mvn dependency:go-offline
This will pull the dependencies to the local repo.
A more direct solution is dependency:get, but it's a lot of arguments to type:
mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version
I myself have a header dedicated to declaring constant NSStrings used for preferences like so:
extern NSString * const PPRememberMusicList;
extern NSString * const PPLoadMusicAtListLoad;
extern NSString * const PPAfterPlayingMusic;
extern NSString * const PPGotoStartupAfterPlaying;
Then declaring them in the accompanying .m file:
NSString * const PPRememberMusicList = @"Remember Music List";
NSString * const PPLoadMusicAtListLoad = @"Load music when loading list";
NSString * const PPAfterPlayingMusic = @"After playing music";
NSString * const PPGotoStartupAfterPlaying = @"Go to startup pos. after playing";
This approach has served me well.
Edit: Note that this works best if the strings are used in multiple files. If only one file uses it, you can just do #define kNSStringConstant @"Constant NSString"
in the .m file that uses the string.
Serial sends data 8 bits at a time, that translates to 1 byte and 1 byte means 1 character.
You need to implement your own method that can read characters into a buffer until some sentinel is reached. The convention is to send a message like 12431\n
indicating one line.
So what you need to do is to implement a buffer that will store X number of characters and as soon as you reach that \n
, perform your operation on the line and proceed to read the next line into the buffer.
Note you will have to take care of buffer overflow cases i.e. when a line is received that is longer than your buffer etc...
EDIT
import serial
ser = serial.Serial(
port='COM5',\
baudrate=9600,\
parity=serial.PARITY_NONE,\
stopbits=serial.STOPBITS_ONE,\
bytesize=serial.EIGHTBITS,\
timeout=0)
print("connected to: " + ser.portstr)
#this will store the line
line = []
while True:
for c in ser.read():
line.append(c)
if c == '\n':
print("Line: " + ''.join(line))
line = []
break
ser.close()
I've used these shortcuts in the past (note: separate key strokes i.e. tap z, let go, tap the subsequent key):
z enter --> moves current line to top of screen
z . --> moves current line to center of screen
z - --> moves current line to bottom
If it's not obvious:
enter means the Return or Enter key.
. means the DOT or "full stop" key (.
).
- means the HYPHEN key (-
)
For what it's worth, z. avoids the danger of saving and closing Vi by accidentally typing ZZ if the caps-lock is on.
Your query will work in MYSQL
if you set to disable ONLY_FULL_GROUP_BY
server mode (and by default It is). But in this case, you are using different RDBMS. So to make your query work, add all non-aggregated columns to your GROUP BY
clause, eg
SELECT col1, col2, SUM(col3) totalSUM
FROM tableName
GROUP BY col1, col2
Non-Aggregated columns means the column is not pass into aggregated functions like SUM
, MAX
, COUNT
, etc..
'To return the position of an element within any-dimension array

posInArray = -1
If IsArray(aArray) Then
If not IsEmpty(aArray) Then

For Each item In aArray
If itemSearched = item Then
posInArray = pos
Exit Function
End If
pos = pos + 1

Adding the keyword 'LOCAL' to my query worked for me:
LOAD DATA LOCAL INFILE 'file_name' INTO TABLE table_name
A detailed description of the keyword can be found here.
There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.
SQLDataReaders are forward-only. You're essentially doing this:
count++; // initially 1
.DataBind(); //consuming all the records
//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1
You could do this instead:
if (reader.HasRows)
{
rep.DataSource = reader;
rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.
Try this
