In case anyone is strugling to do this in kotlin, this code works like a charm. To avoid inconsistencies I also use .toUpperCase and Trim(). then i cast this function:
fun stripAccents(s: String):String{
if (s == null) {
return "";
}
val chars: CharArray = s.toCharArray()
var sb = StringBuilder(s)
var cont: Int = 0
while (chars.size > cont) {
var c: kotlin.Char
c = chars[cont]
var c2:String = c.toString()
//these are my needs, in case you need to convert other accents just Add new entries aqui
c2 = c2.replace("Ã", "A")
c2 = c2.replace("Õ", "O")
c2 = c2.replace("Ç", "C")
c2 = c2.replace("Á", "A")
c2 = c2.replace("Ó", "O")
c2 = c2.replace("Ê", "E")
c2 = c2.replace("É", "E")
c2 = c2.replace("Ú", "U")
c = c2.single()
sb.setCharAt(cont, c)
cont++
}
return sb.toString()
}
to use these fun cast the code like this:
var str: String
str = editText.text.toString() //get the text from EditText
str = str.toUpperCase().trim()
str = stripAccents(str) //call the function
A much more secure way to check if property exists on the object is to use empty object or object prototype to call hasOwnProperty()
var foo = {
hasOwnProperty: function() {
return false;
},
bar: 'Here be dragons'
};
foo.hasOwnProperty('bar'); // always returns false
// Use another Object's hasOwnProperty and call it with 'this' set to foo
({}).hasOwnProperty.call(foo, 'bar'); // true
// It's also possible to use the hasOwnProperty property from the Object
// prototype for this purpose
Object.prototype.hasOwnProperty.call(foo, 'bar'); // true
Reference from MDN Web Docs - Object.prototype.hasOwnProperty()
text doesn't work with len function.
ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

There are no auto incrementing features in Oracle for a column. You need to create a SEQUENCE object. You can use the sequence like:
insert into table(batch_id, ...) values(my_sequence.nextval, ...)
...to return the next number. To find out the last created sequence nr (in your session), you would use:
my_sequence.currval
This site has several complete examples on how to use sequences.
-XX:PermSize
specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize
.
I was facing the similar type of issue: Code Snippet :
<c:forEach items="${orderList}" var="xx">
${xx.id} <br>
</c:forEach>
There was a space after orderlist like this : "${orderList} " because of which the xx variable was getting coverted into String and was not able to call xx.id.
So make sure about space. They play crucial role sometimes. :p
How about exporting the variable, but only inside the subshell?:
(export FOO=bar && somecommand someargs | somecommand2)
Keith has a point, to unconditionally execute the commands, do this:
(export FOO=bar; somecommand someargs | somecommand2)
The original code you suggest is the best way.
Matlab is extremely good at vectorized operations such as this, at least for large vectors.
The built-in norm function is very fast. Here are some timing results:
V = rand(10000000,1);
% Run once
tic; V1=V/norm(V); toc % result: 0.228273s
tic; V2=V/sqrt(sum(V.*V)); toc % result: 0.325161s
tic; V1=V/norm(V); toc % result: 0.218892s
V1 is calculated a second time here just to make sure there are no important cache penalties on the first call.
Timing information here was produced with R2008a x64 on Windows.
EDIT:
Revised answer based on gnovice's suggestions (see comments). Matrix math (barely) wins:
clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V); end; toc % 6.3 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 9.3 s
tic; for i=1:N, V3 = V/sqrt(V'*V); end; toc % 6.2 s ***
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 9.2 s
tic; for i=1:N, V1=V/norm(V); end; toc % 6.4 s
IMHO, the difference between "norm(V)" and "sqrt(V'*V)" is small enough that for most programs, it's best to go with the one that's more clear. To me, "norm(V)" is clearer and easier to read, but "sqrt(V'*V)" is still idiomatic in Matlab.
I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).

Linux kernel 5.0 source comments
I knew that x86 specifics are under arch/x86
, and that syscall stuff goes under arch/x86/entry
. So a quick git grep rdi
in that directory leads me to arch/x86/entry/entry_64.S:
/*
* 64-bit SYSCALL instruction entry. Up to 6 arguments in registers.
*
* This is the only entry point used for 64-bit system calls. The
* hardware interface is reasonably well designed and the register to
* argument mapping Linux uses fits well with the registers that are
* available when SYSCALL is used.
*
* SYSCALL instructions can be found inlined in libc implementations as
* well as some other programs and libraries. There are also a handful
* of SYSCALL instructions in the vDSO used, for example, as a
* clock_gettimeofday fallback.
*
* 64-bit SYSCALL saves rip to rcx, clears rflags.RF, then saves rflags to r11,
* then loads new ss, cs, and rip from previously programmed MSRs.
* rflags gets masked by a value from another MSR (so CLD and CLAC
* are not needed). SYSCALL does not save anything on the stack
* and does not change rsp.
*
* Registers on entry:
* rax system call number
* rcx return address
* r11 saved rflags (note: r11 is callee-clobbered register in C ABI)
* rdi arg0
* rsi arg1
* rdx arg2
* r10 arg3 (needs to be moved to rcx to conform to C ABI)
* r8 arg4
* r9 arg5
* (note: r12-r15, rbp, rbx are callee-preserved in C ABI)
*
* Only called from user space.
*
* When user can change pt_regs->foo always force IRET. That is because
* it deals with uncanonical addresses better. SYSRET has trouble
* with them due to bugs in both AMD and Intel CPUs.
*/
and for 32-bit at arch/x86/entry/entry_32.S:
/*
* 32-bit SYSENTER entry.
*
* 32-bit system calls through the vDSO's __kernel_vsyscall enter here
* if X86_FEATURE_SEP is available. This is the preferred system call
* entry on 32-bit systems.
*
* The SYSENTER instruction, in principle, should *only* occur in the
* vDSO. In practice, a small number of Android devices were shipped
* with a copy of Bionic that inlined a SYSENTER instruction. This
* never happened in any of Google's Bionic versions -- it only happened
* in a narrow range of Intel-provided versions.
*
* SYSENTER loads SS, ESP, CS, and EIP from previously programmed MSRs.
* IF and VM in RFLAGS are cleared (IOW: interrupts are off).
* SYSENTER does not save anything on the stack,
* and does not save old EIP (!!!), ESP, or EFLAGS.
*
* To avoid losing track of EFLAGS.VM (and thus potentially corrupting
* user and/or vm86 state), we explicitly disable the SYSENTER
* instruction in vm86 mode by reprogramming the MSRs.
*
* Arguments:
* eax system call number
* ebx arg1
* ecx arg2
* edx arg3
* esi arg4
* edi arg5
* ebp user stack
* 0(%ebp) arg6

glibc 2.29 Linux x86_64 system call implementation
Now let's cheat by looking at a major libc implementations and see what they are doing.
What could be better than looking into glibc that I'm using right now as I write this answer? :-)
glibc 2.29 defines x86_64 syscalls at sysdeps/unix/sysv/linux/x86_64/sysdep.h
and that contains some interesting code, e.g.:
/* The Linux/x86-64 kernel expects the system call parameters in
registers according to the following table:
syscall number rax
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 r10
arg 5 r8
arg 6 r9
The Linux kernel uses and destroys internally these registers:
return address from
syscall rcx
eflags from syscall r11
Normal function call, including calls to the system call stub
functions in the libc, get the first six parameters passed in
registers and the seventh parameter and later on the stack. The
register use is as follows:
system call number in the DO_CALL macro
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 rcx
arg 5 r8
arg 6 r9
We have to take care that the stack is aligned to 16 bytes. When
called the stack is not aligned since the return address has just
been pushed.
Syscalls of more than 6 arguments are not supported. */
and:
/* Registers clobbered by syscall. */
# define REGISTERS_CLOBBERED_BY_SYSCALL "cc", "r11", "cx"
#undef internal_syscall6
#define internal_syscall6(number, err, arg1, arg2, arg3, arg4, arg5, arg6) \
({ \
unsigned long int resultvar; \
TYPEFY (arg6, __arg6) = ARGIFY (arg6); \
TYPEFY (arg5, __arg5) = ARGIFY (arg5); \
TYPEFY (arg4, __arg4) = ARGIFY (arg4); \
TYPEFY (arg3, __arg3) = ARGIFY (arg3); \
TYPEFY (arg2, __arg2) = ARGIFY (arg2); \
TYPEFY (arg1, __arg1) = ARGIFY (arg1); \
register TYPEFY (arg6, _a6) asm ("r9") = __arg6; \
register TYPEFY (arg5, _a5) asm ("r8") = __arg5; \
register TYPEFY (arg4, _a4) asm ("r10") = __arg4; \
register TYPEFY (arg3, _a3) asm ("rdx") = __arg3; \
register TYPEFY (arg2, _a2) asm ("rsi") = __arg2; \
register TYPEFY (arg1, _a1) asm ("rdi") = __arg1; \
asm volatile ( \
"syscall\n\t" \
: "=a" (resultvar) \
: "0" (number), "r" (_a1), "r" (_a2), "r" (_a3), "r" (_a4), \
"r" (_a5), "r" (_a6) \
: "memory", REGISTERS_CLOBBERED_BY_SYSCALL); \
(long int) resultvar; \
})
which I feel are pretty self explanatory. Note how this seems to have been designed to exactly match the calling convention of regular System V AMD64 ABI functions: https://en.wikipedia.org/wiki/X86_calling_conventions#List_of_x86_calling_conventions
Quick reminder of the clobbers:
cc
means flag registers. But Peter Cordes comments that this is unnecessary here.memory
means that a pointer may be passed in assembly and used to access memoryFor an explicit minimal runnable example from scratch see this answer: How to invoke a system call via syscall or sysenter in inline assembly?
Make some syscalls in assembly manually
Not very scientific, but fun:
x86_64.S

mov $1, %rdi /* stdout */
mov $msg, %rsi /* buffer */
mov $len, %rdx /* len */
syscall
/* exit */
mov $60, %rax /* syscall number */
mov $0, %rdi /* exit status */
syscall
msg:
.ascii "hello\n"
len = . - msg

Just add this one-line class in your CSS, and use the bootstrap label
component.
.label-as-badge {
border-radius: 1em;
}
Compare this label
and badge
side by side:
<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>
They appear the same. But in the CSS, label
uses em
so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:
<span class="label label-success label-as-badge">Yay! Rah!</span>
Or where things are bigger:
<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
<span class="label label-success label-as-badge">Yay! Rah!</span>
</div>
11/16/2015: Looking at how we'll do this in Bootstrap 4
Looks like .badge
classes are completely gone. But there's a built-in .label-pill
class (here) that looks like what we want.
.label-pill {
padding-right: .6em;
padding-left: .6em;
border-radius: 10rem;
}
In use it looks like this:
<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>
11/04/2014: Here's an update on why cross-pollinating alert classes with .badge
is not so great. I think this picture sums it up:
Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.
The .label-as-badge
solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge
class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.
Yep, it is easier to just hack away and drop in those .alert-xxxxx
classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.
Hope here is the exact what we are looking for.

Params contains the following three groups of parameters:
match '/user/:id'

and params[:action]
is always available and contains the current controller and actionJust pass the array to the Set constructor. The Set constructor accepts an iterable
parameter. The Array object implements the iterable
protocol, so its a valid parameter.

Tackling this task, I'd first find the number of decimal places in x
, then round y
accordingly. I'd use:
y.toFixed(x.toString().split(".")[1].length);
It should convert x
to a string, split it over the decimal point, find the length of the right part, and then y.toFixed(length)
should round y
based on that length.
Overwrite the dataframe with something like that
import pandas as pd
df = pd.DataFrame(None)
or if you want to keep columns in place
df = pd.DataFrame(columns=df.columns)
You are modifying the list book_shop.values()[i]
, which is not getting updated in the dictionary. Whenever you call the values()
method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.
I would suggest you to either use <table>
or CSS.
CSS is preferred for being more flexible. An example would be:
<!-- of course, you should move the inline CSS style to your stylesheet -->
<!-- main container, width = 70% of page, centered -->
<div id="contentBox" style="margin:0px auto; width:70%">
<!-- columns divs, float left, no margin so there is no space between column, width=1/3 -->
<div id="column1" style="float:left; margin:0; width:33%;">
CONTENT
</div>
<div id="column2" style="float:left; margin:0;width:33%;">
CONTENT
</div>
<div id="column3" style="float:left; margin:0;width:33%">
CONTENT
</div>
</div>
jsFiddle: http://jsfiddle.net/ndhqM/
Using float:left would make 3 columns stick to each other, coming in from left inside the centered div "content box".
Using Stack
, here are the steps to follow: Push the first vertex on the stack then,
Here's the Java program following the above steps:
public void searchDepthFirst() {
// begin at vertex 0
vertexList[0].wasVisited = true;
displayVertex(0);
stack.push(0);
while (!stack.isEmpty()) {
int adjacentVertex = getAdjacentUnvisitedVertex(stack.peek());
// if no such vertex
if (adjacentVertex == -1) {
stack.pop();
} else {
vertexList[adjacentVertex].wasVisited = true;
// Do something
stack.push(adjacentVertex);
}
}
// stack is empty, so we're done, reset flags
for (int j = 0; j < nVerts; j++)
vertexList[j].wasVisited = false;
}
You can easily pick image from asset without UIImage(named: "green-square-Retina")
.
Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.
See this Stackoverflow answer for reference.
I typically bind this data using the RowDatabound event with the GridView:
protected void FormatGridView(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((Button)e.Row.Cells(0).FindControl("btnSpecial")).CommandArgument = e.Row.RowIndex.ToString();
}
}
You can create a custom directive that is somehow similar to ng-disabled and disable a specific set of elements by:
my-disabled
.HTML
<a my-disabled="disableCreate" href="#" ng-click="disableEdit = true">CREATE</a><br/>
<a my-disabled="disableEdit" href="#" ng-click="disableCreate = true">EDIT</a><br/>
<a my-disabled="disableCreate || disableEdit" href="#">DELETE</a><br/>
<a href="#" ng-click="disableEdit = false; disableCreate = false;">RESET</a>
JAVASCRIPT
directive('myDisabled', function() {
return {
link: function(scope, elem, attr) {
var color = elem.css('color'),
textDecoration = elem.css('text-decoration'),
cursor = elem.css('cursor'),
// double negation for non-boolean attributes e.g. undefined
currentValue = !!scope.$eval(attr.myDisabled),
current = elem[0],
next = elem[0].cloneNode(true);
var nextElem = angular.element(next);
nextElem.on('click', function(e) {
e.preventDefault();
e.stopPropagation();
});
nextElem.css('color', 'gray');
nextElem.css('text-decoration', 'line-through');
nextElem.css('cursor', 'not-allowed');
nextElem.attr('tabindex', -1);
scope.$watch(attr.myDisabled, function(value) {
// double negation for non-boolean attributes e.g. undefined
value = !!value;
if(currentValue != value) {
currentValue = value;
current.parentNode.replaceChild(next, current);
var temp = current;
current = next;
next = temp;
}
})
}
}
});
I use ALT-left and ALT-right to pop/push from/to the tag stack.
" Alt-right/left to navigate forward/backward in the tags stack
map <M-Left> <C-T>
map <M-Right> <C-]>
If you use hjkl
for movement you can map <M-h>
and <M-l>
instead.
The use of -X [WHATEVER]
merely changes the request's method string used in the HTTP request. This is easier to understand with two examples — one with -X [WHATEVER]
and one without — and the associated HTTP request headers for each:
# curl -XPANTS -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.224.86.126) port 80 (#0)
> PANTS / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*
# curl -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.33.50.167) port 80 (#0)
> GET / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*
If you already have the string, you can use this function:
bool isNumber( const string& s )
{
bool hitDecimal=0;
for( char c : s )
{
if( c=='.' && !hitDecimal ) // 2 '.' in string mean invalid
hitDecimal=1; // first hit here, we forgive and skip
else if( !isdigit( c ) )
return 0 ; // not ., not
}
return 1 ;
}
Have you looked into easy_install at all? It won't synchronize your macports or anything like that, but it will automatically download the latest package and all necessary dependencies, i.e.
easy_install nose
for the nose unit testing package, or
easy_install trac
for the trac
bug tracker.
There's a bit more information on their EasyInstall page too.
This works:
sc.exe config "[servicename]" obj= "[.\username]" password= "[password]"
Where each of the [bracketed] items are replaced with the true arguments. (Keep the quotes, but don't keep the brackets.)
Just keep in mind that:
obj= "foo"
is correct; obj="foo"
is not.col_Names=["Sequence", "Start", "End", "Coverage"]
my_CSV_File= pd.read_csv("yourCSVFile.csv",names=col_Names)
having done this, just check it with[well obviously I know, u know that. But still...

If the mouse over for all over the component is your option, you can directly is @hostListener
to handle the events to perform the mouse over al below.
import {HostListener} from '@angular/core';
@HostListener('mouseenter') onMouseEnter() {
this.hover = true;
this.elementRef.nativeElement.addClass = 'edit';
}
@HostListener('mouseleave') onMouseLeave() {
this.hover = false;
this.elementRef.nativeElement.addClass = 'un-edit';
}
Its available in @angular/core
. I tested it in angular 4.x.x
How can I display these open transactions and commit or cancel them?
There is no open transaction, MySQL will rollback the transaction upon disconnect.
You cannot commit the transaction (IFAIK).
You display threads using
SHOW FULL PROCESSLIST
See: http://dev.mysql.com/doc/refman/5.1/en/thread-information.html
It will not help you, because you cannot commit a transaction from a broken connection.
What happens when a connection breaks
From the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/mysql-tips.html
4.5.1.6.3. Disabling mysql Auto-Reconnect
If the mysql client loses its connection to the server while sending a statement, it immediately and automatically tries to reconnect once to the server and send the statement again. However, even if mysql succeeds in reconnecting, your first connection has ended and all your previous session objects and settings are lost: temporary tables, the autocommit mode, and user-defined and session variables. Also, any current transaction rolls back.
This behavior may be dangerous for you, as in the following example where the server was shut down and restarted between the first and second statements without you knowing it:
Also see: http://dev.mysql.com/doc/refman/5.0/en/auto-reconnect.html
How to diagnose and fix this
To check for auto-reconnection:
If an automatic reconnection does occur (for example, as a result of calling mysql_ping()), there is no explicit indication of it. To check for reconnection, call
mysql_thread_id()
to get the original connection identifier before callingmysql_ping()
, then callmysql_thread_id()
again to see whether the identifier has changed.
Make sure you keep your last query (transaction) in the client so that you can resubmit it if need be.
And disable auto-reconnect mode, because that is dangerous, implement your own reconnect instead, so that you know when a drop occurs and you can resubmit that query.
'nunique' is an option for .agg() since pandas 0.20.0, so:
df.groupby('date').agg({'duration': 'sum', 'user_id': 'nunique'})
calling getImageData every time will slow the process ... to speed up things i recommend store image data and then you can get pix value easily and quickly, so do something like this for better performance
// keep it global
let imgData = false; // initially no image data we have
// create some function block
if(imgData === false){
// fetch once canvas data
var ctx = canvas.getContext("2d");
imgData = ctx.getImageData(0, 0, canvas.width, canvas.height);
}
// Prepare your X Y coordinates which you will be fetching from your mouse loc
let x = 100; //
let y = 100;
// locate index of current pixel
let index = (y * imgData.width + x) * 4;
let red = imgData.data[index];
let green = imgData.data[index+1];
let blue = imgData.data[index+2];
let alpha = imgData.data[index+3];
// Output
console.log('pix x ' + x +' y '+y+ ' index '+index +' COLOR '+red+','+green+','+blue+','+alpha);
you need to do something like this,
SELECT * FROM buckets WHERE bucketname RLIKE 'Stylus.*2100';
or
SELECT * FROM buckets WHERE bucketname RLIKE '(Stylus)+.*(2100)+';
Percent calculation that worked for me:
(new_num - old_num) / old_num * 100.0
This file give you some more hints, for example, keydown.up doesn't work you need keydown.arrowup:
\p{L}
matches a single code point in the category "letter".
\p{N}
matches any kind of numeric character in any script.

well, for me it was different. I was missing assembly of my console application project with MVC project. So, adding reference was not enough.
well this might help someone else. go to root web.config file system.web
-> compilation
-> add your project reference like this.
<assemblies>
<add assembly="Your.Namespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>

Simplest answer:
function isSafari() {
if (navigator.vendor.match(/[Aa]+pple/g).length > 0 )
return true;
return false;
}
good way:
if(typeof neverDeclared == "undefined") //no errors
But the best looking way is to check via :
if(typeof neverDeclared === typeof undefined) //also no errors and no strings
I resolved that situation in this way. I created a util method that return a object extracted from request body, using the readValue method of ObjectMapper that is capable of receiving a Reader.
public static <T> T getBody(ResourceRequest request, Class<T> class) {
T objectFromBody = null;
try {
ObjectMapper objectMapper = new ObjectMapper();
HttpServletRequest httpServletRequest = PortalUtil.getHttpServletRequest(request);
objectFromBody = objectMapper.readValue(httpServletRequest.getReader(), class);
} catch (IOException ex) {
log.error("Error message", ex);
}
return objectFromBody;
}
You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:
<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>
If you use php:
print_r($_POST['comment'])
you will get this:
Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )

The above answer is great, but there may be some problems when we using pip to install MySQL-python in Windows
for example,It needs some files that are associated with Visual Stdio .One solution is installing VS2008 or 2010……Obviously,it cost too much.
Another way is the answer of @bob90937 . I am here to do something to add.
with http://www.lfd.uci.edu/~gohlke/pythonlibs, u can download many Windows binaries of many scientific open-source extension packages for the official CPython distribution of the Python programming language.
Back to topic,we can choose the MySQL-python(py2) or Mysqlclient(py3) and use pip install to install. it gives us Great convenience!
Iterate through the array, and splice
out the ones you don't want. For easier use, iterate backwards so you don't have to take into account the live nature of the array:
for (var i = myArray.length - 1; i >= 0; --i) {
if (myArray[i].field == "money") {
myArray.splice(i,1);
}
}
Another option if you want to preserve translucency and you don't want to subclass every UINavigationController
in your app:
#import <objc/runtime.h>
@implementation UINavigationController (NoShadow)
+ (void)load {
Method original = class_getInstanceMethod(self, @selector(viewWillAppear:));
Method swizzled = class_getInstanceMethod(self, @selector(swizzled_viewWillAppear:));
method_exchangeImplementations(original, swizzled);
}
+ (UIImageView *)findHairlineImageViewUnder:(UIView *)view {
if ([view isKindOfClass:UIImageView.class] && view.bounds.size.height <= 1.0) {
return (UIImageView *)view;
}
for (UIView *subview in view.subviews) {
UIImageView *imageView = [self findHairlineImageViewUnder:subview];
if (imageView) {
return imageView;
}
}
return nil;
}
- (void)swizzled_viewWillAppear:(BOOL)animated {
UIImageView *shadow = [UINavigationController findHairlineImageViewUnder:self.navigationBar];
shadow.hidden = YES;
[self swizzled_viewWillAppear:animated];
}
@end
Yes, make the shortcut's path
%comspec% /k <command>
where
%comspec%
is the environment variable for cmd.exe's full path, equivalent to C:\Windows\System32\cmd.exe
on most (if not all) Windows installs/k
keeps the window open after the command has run, this may be replaced with /c
if you want the window to close once the command is finished running<command>
is the command you wish to runThere is a method object_of_ViewPager.getCurrentItem()
which returns the position of currently Viewed page of view pager
Chain selectors are not limited just to classes, you can do it for both classes and ids.
Classes
.classA.classB {
/*style here*/
}
Class & Id
.classA#idB {
/*style here*/
}
Id & Id
#idA#idB {
/*style here*/
}
All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".
For your case
li.left.ui-class-selector {
/*style here*/
}
or
.left.ui-class-selector {
/*style here*/
}
<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>
That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em'
as the measurement, you may want to use other units, like 'px'
.
EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:
In your HTML page, containing the <p>
tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:
<head>
<style type="text/css">
p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>
So above, all <p>
elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:
<head>
<style type="text/css">
.container p { margin-left:5em; /* Or another measurement unit, like px */ }
</style>
</head>
<body>
<div class="container">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</div>
<p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>
In the example above, only the <p>
element inside the div, whose class name is 'container', will have the styles applied - and not the <p>
element outside the container.
In addition to the above, you can collect your styles together and remove the style element from the <head>
tag, replacing it with a <link>
tag, which points to an external CSS file. This external file is where you'd now put your <p>
tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.
You can change the labels' text by adorning the property with the DisplayName
attribute.
[DisplayName("Someking Status")]
public string SomekingStatus { get; set; }
Or, you could write the raw HTML explicitly:
<label for="SomekingStatus" class="control-label">Someking Status</label>
An easy way to execute .jar files is to create a batch file.
Let's say you placed your jar file on your Desktop;
@echo OFF
java -jar C:\Users\YourName\Desktop\myjar.jar
Copy this code to a .txt file, modify "YourName" and save as "myjar.bat". Then whenever you double click, the jar file will be executed. Hope this helps.
Without knowing what your data looks like, i.e. the complexity, size, etc...XML is easy to maintain and easily accessible. I would NOT use an Access database, and flat files are more difficult to maintain over the long haul, particularly if you are dealing with more than one data field/element in your file.
I deal with large flat-file data feeds in good quantities daily, and even though an extreme example, flat-file data is much more difficult to maintain than the XML data feeds I process.
A simple example of loading XML data into a dataset using C#:
DataSet reportData = new DataSet();
reportData.ReadXml(fi.FullName);
You can also check out LINQ to XML as an option for querying the XML data...
HTH...
switch (name) {
case text1, text4 -> // do something ;
case text2, text3, text 5 -> // do something else ;
default -> // default case ;
}
You can also assign a value through the switch case expression :
String text = switch (name) {
case text1, text4 -> "hello" ;
case text2, text3, text5 -> "world" ;
default -> "goodbye";
};
It allows you to return a value by the switch case expression
String text = switch (name) {
case text1, text4 ->
yield "hello";
case text2, text3, text5 ->
yield "world";
default ->
yield "goodbye";
};
lint is a tool that is used to mark the source code with some suspicious and non-structural (may cause bug). It is a static code analysis tool in C at the beginning.Now it became the generic term used to describe the software analysis tool that mark the suspicious code.
I'm kinda late to the party, but you can use this module: crypto:
const crypto = require('crypto');
const SALT = '$ome$alt';
function generateHash(pass) {
return crypto.createHmac('sha256', SALT)
.update(pass)
.digest('hex');
}
The result of this function is always is 64
characters string; something like this: "aa54e7563b1964037849528e7ba068eb7767b1fab74a8d80fe300828b996714a"
You didn't bind all your bindings here
$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate FROM comments WHERE articleid = :art
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";
$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );
You've declared a binding called :numRows but you never actually bind anything to it.
UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion
Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.
In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)
The CPPFLAGS
macro is the one to use to specify #include
directories.
Both CPPFLAGS
and CFLAGS
work in your case because the make
(1) rule combines both preprocessing and compiling in one command (so both macros are used in the command).
You don't need to specify .
as an include-directory if you use the form #include "..."
. You also don't need to specify the standard compiler include directory. You do need to specify all other include-directories.
You can also use the "Spring Boot App" run configuration. For that you'll need to install the Spring Tool Suite plug-in for Eclipse (STS).
Just my 2 cents regarding the divs option.
Famous/Infamous and SamsaraJS (and possibly others) use absolutely positioned non-nested divs (with non-trivial HTML/CSS content), combined with matrix2d/matrix3d for positioning and 2D/3D transformations, and achieve a stable 60FPS on moderate mobile hardware, so I'd argue against divs being a slow option.
There are plenty of screen recordings on Youtube and elsewhere, of high-performance 2D/3D stuff running in the browser with everything being an DOM element which you can Inspect Element on, at 60FPS (mixed with WebGL for certain effects, but not for the main part of the rendering).
It does not work because your foobar.go
source file is not in a directory called foobar
. go build
and go install
try to match directories, not source files.
$GOPATH
to a valid directory, e.g. export GOPATH="$HOME/go"
foobar.go
to $GOPATH/src/foobar/foobar.go
and building should work just fine.Additional recommended steps:
$GOPATH/bin
to your $PATH
by: PATH="$GOPATH/bin:$PATH"
main.go
to a subfolder of $GOPATH/src
, e.g. $GOPATH/src/test
go install test
should now create an executable in $GOPATH/bin
that can be called by typing test
into your terminal.format
The following is excerpt from the documentation:
Given
format % values
,%
conversion specifications informat
are replaced with zero or more elements ofvalues
. The effect is similar to the usingsprintf()
in the C language.If
format
requires a single argument, values may be a single non-tuple object. Otherwise, values must be a tuple with exactly the number of items specified by theformat
string, or a single mapping object (for example, a dictionary).
str.format
instead of %
A newer alternative to %
operator is to use str.format
. Here's an excerpt from the documentation:
str.format(*args, **kwargs)
Perform a string formatting operation. The string on which this method is called can contain literal text or replacement fields delimited by braces
{}
. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of the string where each replacement field is replaced with the string value of the corresponding argument.This method is the new standard in Python 3.0, and should be preferred to
%
formatting.
Here are some usage examples:
>>> '%s for %s' % ("tit", "tat")
tit for tat
>>> '{} and {}'.format("chicken", "waffles")
chicken and waffles
>>> '%(last)s, %(first)s %(last)s' % {'first': "James", 'last': "Bond"}
Bond, James Bond
>>> '{last}, {first} {last}'.format(first="James", last="Bond")
Bond, James Bond
If you just want to get the information of current directory, you can type:
pwd
and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.
The singular form dtype
is used to check the data type for a single column. And the plural form dtypes
is for data frame which returns data types for all columns. Essentially:
For a single column:
dataframe.column.dtype
For all columns:
dataframe.dtypes
Example:
import pandas as pd
df = pd.DataFrame({'A': [1,2,3], 'B': [True, False, False], 'C': ['a', 'b', 'c']})
df.A.dtype
# dtype('int64')
df.B.dtype
# dtype('bool')
df.C.dtype
# dtype('O')
df.dtypes
#A int64
#B bool
#C object
#dtype: object
The easiest and the most correct (and legal) way is to use graph api.
Just perform the request: http://graph.facebook.com/4
which returns
{
"id": "4",
"name": "Mark Zuckerberg",
"first_name": "Mark",
"last_name": "Zuckerberg",
"link": "http://www.facebook.com/zuck",
"username": "zuck",
"gender": "male",
"locale": "en_US"
}
and take the link
key.
You can also reduce the traffic by using fields
parameter: http://graph.facebook.com/4?fields=link to get only what you need:
{
"link": "http://www.facebook.com/zuck",
"id": "4"
}
int64_t
is guaranteed by the C99 standard to be exactly 64 bits wide on platforms that implement it, there's no such guarantee for a long
which is at least 32 bits so it could be more.
§7.18.1.3 Exact-width integer types 1 The typedef name intN_t designates a signed integer type with width N , no padding bits, and a two’s complement representation. Thus, int8_t denotes a signed integer type with a width of exactly 8 bits.

Now if you paste above code. you will see following result on your device.
Interestingly enough I tried both of these in LinqPad and the variant using group from Dmitry Gribkov by appears to be quicker. (also the final distinct is not required as the result is already distinct.
My (somewhat simple) code was:
public class Pair
{
public int id {get;set;}
public string Arb {get;set;}
}
void Main()
{
var theList = new List<Pair>();
var randomiser = new Random();
for (int count = 1; count < 10000; count++)
{
theList.Add(new Pair
{
id = randomiser.Next(1, 50),
Arb = "not used"
});
}
var timer = new Stopwatch();
timer.Start();
var distinct = theList.GroupBy(c => c.id).Select(p => p.First().id);
timer.Stop();
Debug.WriteLine(timer.Elapsed);
timer.Start();
var otherDistinct = theList.Select(p => p.id).Distinct();
timer.Stop();
Debug.WriteLine(timer.Elapsed);
}
If you want to send emails simultaneously to all the admins, you can do something like this:
In your .env file add all the emails as comma separated values:
[email protected],[email protected],[email protected]
so when you going to send the email just do this (yes! the 'to' method of message builder instance accepts an array):
So,
$to = explode(',', env('ADMIN_EMAILS'));
and...
$message->to($to);
will now send the mail to all the admins.
Though I'm usually against it (though in this case it seems that you have a genuine reason), have you tried providing any query hints on the SP version of the query? If SQL Server is preparing a different execution plan in those two instances, can you use a hint to tell it what index to use, so that the plan matches the first one?
For some examples, you can go here.
EDIT: If you can post your query plan here, perhaps we can identify some difference between the plans that's telling.
SECOND: Updated the link to be SQL-2000 specific. You'll have to scroll down a ways, but there's a second titled "Table Hints" that's what you're looking for.
THIRD: The "Bad" query seems to be ignoring the [IX_Openers_SessionGUID] on the "Openers" table - any chance adding an INDEX hint to force it to use that index will change things?
"not equal"
So in this case, $RESULT
is tested to not be equal to zero.
However, the test is done numerically, not alphabetically:
n1 -ne n2 True if the integers n1 and n2 are not algebraically equal.
compared to:
s1 != s2 True if the strings s1 and s2 are not identical.
You can use the values 'TRUE'
and 'FALSE'
.
From https://docs.microsoft.com/en-us/sql/t-sql/data-types/bit-transact-sql:
The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.
In my case it was a property that gave me the error, the correct writing and still gave me the error in the console. I searched so much and nothing worked for me, until I gave him Ctrl + F5 and Voilá! error was removed. :'v
you can use visual studio for java http://visualstudiogallery.msdn.microsoft.com/bc561769-36ff-4a40-9504-e266e8706f93
If you are running the .sh from a ssh connection with a tool like MobaXTerm, and if said tool has an autosave utility to edit remote file from local machine, that will lock the file.
Closing and reopening the SSH session solves it.
pathlib
module (python's object-oriented filesystem paths)Just for kicks, this is perhaps the latest pythonic version of the solution.
from pathlib import Path
path = Path(f'{player}.txt')
path.touch() # default exists_ok=True
with path.open('a') as highscore:
highscore.write(f'Username:{player}')
For me, the solution given on the page maven is not able to download anything from central because ssl don't work worked, when running Mint 19 in a VM:
sudo apt install ca-certificates-java
sudo update-ca-certificates -f
It's pretty easy. First of all send to the view decoded variable (see Laravel Views):
view('your-view')->with('leads', json_decode($leads, true));
Then just use common blade constructions (see Laravel Templating):
@foreach($leads['member'] as $member)
Member ID: {{ $member['id'] }}
Firstname: {{ $member['firstName'] }}
Lastname: {{ $member['lastName'] }}
Phone: {{ $member['phoneNumber'] }}
Owner ID: {{ $member['owner']['id'] }}
Firstname: {{ $member['owner']['firstName'] }}
Lastname: {{ $member['owner']['lastName'] }}
@endforeach
I've heard from a reliable source that, if you're doing HTML parsing in .Net, you should look at the HTML agility pack again..

Some sample on SO..
Actually go to the main folder (deployment package)that you want to zip,
Inside that folder select all files and then create the zip and upload that zip
In short, a||=b
means: If a
is undefined, nil or false
, assign b
to a
. Otherwise, keep a
intact.
By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init
. I've used the below script to first create the plot, then I determined a good elevation, or elev
, from which to view my plot. I then adjusted the azimuth angle, or azim
, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.
from mpl_toolkits.mplot3d import Axes3D
ax = Axes3D(fig)
ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
for ii in xrange(0,360,1):
ax.view_init(elev=10., azim=ii)
savefig("movie%d.png" % ii)
<a class="menu_links" onclick="displayData(11,1,0,'A')" onmouseover="" style="cursor: pointer;"> A </a>
It's css.
Or in a style sheet:
a.menu_links { cursor: pointer; }
In PHP 7 you can write it even shorter:
$age = $_GET['age'] ?? 27;
This means that the $age
variable will be set to the age
parameter if it is provided in the URL, or it will default to 27.
See all new features of PHP 7.

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.
If you don't want word wrap, assign the CSS style white-space: nowrap
to the cells.
The question is how to call a C function from Python, if I understood correctly. Then the best bet are Ctypes (BTW portable across all variants of Python).
>>> from ctypes import *
>>> libc = cdll.msvcrt
>>> print libc.time(None)
1438069008
>>> printf = libc.printf
>>> printf("Hello, %s\n", "World!")
Hello, World!

>>> printf("%d bottles of beer\n", 42)
42 bottles of beer

A pure Swift approach with protocol inheritance:
//Required methods
protocol MyProtocol {
func foo()
}
//Optional methods
protocol MyExtendedProtocol: MyProtocol {
func bar()
}
class MyClass {
var delegate: MyProtocol
func myMethod() {
(delegate as? MyExtendedProtocol).bar()
}
}
server {
server_name example.com;
root /path/to/root;
location / {
# bla bla
}
location /demo {
alias /path/to/root/production/folder/here;
}
}
If you need to use try_files
inside /demo
you'll need to replace alias
with a root
and do a rewrite because of the bug explained here
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
In the case you want to pass a dynamic sized 2-d array to a function, using some pointers could work for you.
void func1(int *arr, int n, int m){
...
int i_j_the_element = arr[i * m + j]; // use the idiom of i * m + j for arr[i][j]
...
}
void func2(){
...
int arr[n][m];
...
func1(&(arr[0][0]), n, m);
}
Consider this line of code:
Math.abs(firstDouble - secondDouble) < Double.MIN_NORMAL
It returns whether firstDouble is equal to secondDouble. I'm unsure as to whether or not this would work in your exact case (as Kevin pointed out, performing any math on floating points can lead to imprecise results) however I was having difficulties with comparing two double which were, indeed, equal, and yet using the 'compareTo' method didn't return 0.
I'm just leaving this there in case anyone needs to compare to check if they are indeed equal, and not just similar.
LinkedHashMap
current implementation (Java 8) keeps track of its tail. If performance is a concern and/or the map is large in size, you could access that field via reflection.
Because the implementation may change it is probably a good idea to have a fallback strategy too. You may want to log something if an exception is thrown so you know that the implementation has changed.
It could look like:
public static <K, V> Entry<K, V> getFirst(Map<K, V> map) {
if (map.isEmpty()) return null;
return map.entrySet().iterator().next();
}
public static <K, V> Entry<K, V> getLast(Map<K, V> map) {
try {
if (map instanceof LinkedHashMap) return getLastViaReflection(map);
} catch (Exception ignore) { }
return getLastByIterating(map);
}
private static <K, V> Entry<K, V> getLastByIterating(Map<K, V> map) {
Entry<K, V> last = null;
for (Entry<K, V> e : map.entrySet()) last = e;
return last;
}
private static <K, V> Entry<K, V> getLastViaReflection(Map<K, V> map) throws NoSuchFieldException, IllegalAccessException {
Field tail = map.getClass().getDeclaredField("tail");
tail.setAccessible(true);
return (Entry<K, V>) tail.get(map);
}
Go to: C:\Users\ [youruserdirectory] \bash_profile
In your bash_profile file type - alias desk='cd " [DIRECTORY LOCATION] "'
Refresh your User directory where the bash_profile file exists then reopen your CMD or Git Bash window
Type in desk to see if you get to the Desktop location or the location you want in the "DIRECTORY LOCATION" area above
Note: [ desk ] can be what ever name that you choose and should get you to the location you want to get to when typed in the CMD window.
I would like to share a useful example of overloaded-like approach.
function Clear(control)
{
var o = typeof control !== "undefined" ? control : document.body;
var children = o.childNodes;
while (o.childNodes.length > 0)
o.removeChild(o.firstChild);
}
Usage: Clear(); // Clears all the document
Clear(myDiv); // Clears panel referenced by myDiv
In my case I simply remove
implementation "com.google.android.gms:play-services-ads:16.0.0
and add firebase ads dependencies
implementation 'com.google.firebase:firebase-ads:17.1.2'
Their names can be a bit confusing :). Here's a summary:
The SelectedItem property returns the entire object that your list is bound to. So say you've bound a list to a collection of Category
objects (with each Category object having Name and ID properties). eg. ObservableCollection<Category>
. The SelectedItem
property will return you the currently selected Category
object. For binding purposes however, this is not always what you want, as this only enables you to bind an entire Category object to the property that the list is bound to, not the value of a single property on that Category object (such as its ID
property).
Therefore we have the SelectedValuePath property and the SelectedValue property as an alternative means of binding (you use them in conjunction with one another). Let's say you have a Product
object, that your view is bound to (with properties for things like ProductName, Weight, etc). Let's also say you have a CategoryID
property on that Product object, and you want the user to be able to select a category for the product from a list of categories. You need the ID property of the Category object to be assigned to the CategoryID
property on the Product object. This is where the SelectedValuePath
and the SelectedValue
properties come in. You specify that the ID property on the Category object should be assigned to the property on the Product object that the list is bound to using SelectedValuePath='ID'
, and then bind the SelectedValue
property to the property on the DataContext (ie. the Product).
The example below demonstrates this. We have a ComboBox bound to a list of Categories (via ItemsSource). We're binding the CategoryID property on the Product as the selected value (using the SelectedValue property). We're relating this to the Category's ID property via the SelectedValuePath property. And we're saying only display the Name property in the ComboBox, with the DisplayMemberPath property).
<ComboBox ItemsSource="{Binding Categories}"
SelectedValue="{Binding CategoryID, Mode=TwoWay}"
SelectedValuePath="ID"
DisplayMemberPath="Name" />
public class Category
{
public int ID { get; set; }
public string Name { get; set; }
}
public class Product
{
public int CategoryID { get; set; }
}
It's a little confusing initially, but hopefully this makes it a bit clearer... :)

You can use this ShellScript to install (most) of it's dependencies, clone, build, compile and get all the necessary files into ../src/includes
folder:
https://github.com/node-tensorflow/node-tensorflow/blob/master/tools/install.sh
I'll echo what Dmitriy said, but adding on a point.
I worked on a batch billing system that needed to insert large sets of rows on 30+ tables. We weren't allowed to do a data pump (Oracle) so we had to do bulk inserts. Those tables had foreign keys on them, but we had already ensured that they were not breaking any relationships.
Before insert, we disable the foreign key constraints so that Oracle doesn't take forever doing the inserts. After the insert is successful, we re-enable the constraints.
PS: In a large database with many foreign keys and child row data for a single record, sometimes foreign keys can be bad, and you may want to disallow cascading deletes. For us in the billing system, it would take too long and be too taxing on the database if we did cascading deletes, so we just mark the record as bad with a field on the main driver (parent) table.
I realize this is quite belated, but for the record, you can also use CSS selectors to do this (eliminating the need for inline styles.) This CSS applies padding to the first column of every row:
table > tr > td:first-child { padding-right:10px }
And this would be your HTML, sans CSS!:
<table><tr><td>data</td><td>more data</td></tr></table>
This allows for much more elegant markup, especially in cases where you need to do lots of specific formatting with CSS.
You could try:
import pyodbc
# Using a DSN
cnxn = pyodbc.connect('DSN=odbc_datasource_name;UID=db_user_id;PWD=db_password')
Note: You will need to know the "odbc_datasource_name". In Windows you can search for ODBC Data Sources. The name will look something like this:
String string="this is a text";
editText.setText(string)
I have found String to be a useful Indirect Subclass of CharSequence
http://developer.android.com/reference/android/widget/TextView.html find setText(CharSequence text)
http://developer.android.com/reference/java/lang/CharSequence.html
You can do it like this, and no need to dedicate variable:
Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");
Or a little simplified:
MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");
It works only - after the menu created.
Here is solution for legacy datatable 1.9.4
var myData = [
{
"id": 1,
"first_name": "Andy",
"last_name": "Anderson"
}
];
var myData2 = [
{
"id": 2,
"first_name": "Bob",
"last_name": "Benson"
}
];
$('#table').dataTable({
// data: myData,
aoColumns: [
{ mData: 'id' },
{ mData: 'first_name' },
{ mData: 'last_name' }
]
});
$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);
HTML:
First, we will need to add a class to your text container so that we can access and style it accordingly.
<div class="col-xs-5 textContainer">
<h3 class="text-left">Link up with other gamers all over the world who share the same tastes in games.</h3>
</div>
CSS:
Next, we will apply the following styles to align it vertically, according to the size of the image div next to it.
.textContainer {
height: 345px;
line-height: 340px;
}
.textContainer h3 {
vertical-align: middle;
display: inline-block;
}
All Done! Adjust the line-height and height on the styles above if you believe that it is still slightly out of align.
I experienced this issue and couldn't figure out a fix for a few hours, until I realised I had incorrectly prevented
native events from occurring with:
<input type="checkbox" @click.prevent="toggleConfirmedStatus(render.uuid)"
:checked="confirmed.indexOf(render.uuid) > -1"
:value="render.uuid"
/>
removing the .prevent
from the @click
handler fixed my issue.
If you need direct access:
WScript.Arguments.Item(0)
WScript.Arguments.Item(1)
...
if "ABCD" in "xxxxABCDyyyy":
# whatever

It's easier and cleaner to do it with CSS.
HTML:
<div ng-repeat="file in files" class="file">
{{ file.name }}
</div>
CSS:
.file:last-of-type {
color: #800;
}
The :last-of-type
selector is currently supported by 98% of browsers
Came across this and thought I would point out that for MVC 5 all you need to do is set the value on the model. For Example:
Model:
public class ExampleModel
{
public PackingListInputModel()
{
RadioButtonField = "One";
}
public string RadioButtonField { get; set; }
}
View :
@model ExampleModel
@using (Html.BeginForm)
{
@Html.RadioButtonFor(m => m.RadioButtonField , "One")
@Html.RadioButtonFor(m => m.RadioButtonField , "Two")
}
The state of the first radio button ("One") will be set as active because the value matches what was set in the model.
The @RequestBody
javadoc states
Annotation indicating a method parameter should be bound to the body of the web request.
It uses registered instances of HttpMessageConverter
to deserialize the request body into an object of the annotated parameter type.
And the @RequestParam
javadoc states
Annotation which indicates that a method parameter should be bound to a web request parameter.
Spring binds the body of the request to the parameter annotated with @RequestBody
.
Spring binds request parameters from the request body (url-encoded parameters) to your method parameter. Spring will use the name of the parameter, ie. name
, to map the parameter.
Parameters are resolved in order. The @RequestBody
is processed first. Spring will consume all the HttpServletRequest
InputStream
. When it then tries to resolve the @RequestParam
, which is by default required
, there is no request parameter in the query string or what remains of the request body, ie. nothing. So it fails with 400 because the request can't be correctly handled by the handler method.
The handler for @RequestParam
acts first, reading what it can of the HttpServletRequest
InputStream
to map the request parameter, ie. the whole query string/url-encoded parameters. It does so and gets the value abc
mapped to the parameter name
. When the handler for @RequestBody
runs, there's nothing left in the request body, so the argument used is the empty string.
The handler for @RequestBody
reads the body and binds it to the parameter. The handler for @RequestParam
can then get the request parameter from the URL query string.
The handler for @RequestParam
reads from both the body and the URL query String. It would usually put them in a Map
, but since the parameter is of type String
, Spring will serialize the Map
as comma separated values. The handler for @RequestBody
then, again, has nothing left to read from the body.
WARNING: Security researches have found several poisoned packages on PyPI, including a package named
urllib
, which will 'phone home' when installed. If you usedpip install urllib
some time after June 2017, remove that package as soon as possible.
You can't, and you don't need to.
urllib2
is the name of the library included in Python 2. You can use the urllib.request
library included with Python 3, instead. The urllib.request
library works the same way urllib2
works in Python 2. Because it is already included you don't need to install it.
If you are following a tutorial that tells you to use urllib2
then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2
comes with that version.
Alternatively, install the requests
library for a higher-level and easier to use API. It'll work on both Python 2 and 3.
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.
Something that worked for me was:
python -m pip install -user {package name}
The command does not require sudo. This was tested on OSX Mojave.
When you put <form>
tag inside you ngApp, AngularJS automatically adds form controller (actually there is a directive, called form
that add nessesary behaviour). The value of the name attribute will be bound in your scope; so something like <form name="yourformname">...</form>
will satisfy:
A form is an instance of FormController. The form instance can optionally be published into the scope using the name attribute.
So to check form validity, you can check value of $scope.yourformname.$valid
property of scope.
More information you can get at Developer's Guide section about forms.
The problem you have is related to TCP streaming nature.
The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.
You need to implement a loop in which you read until the whole message was received.
Let me provide an example with DataInputStream
instead of BufferedinputStream
. Something very simple to give you just an example.
Let's suppose you know beforehand the server is to send 100 Bytes of data.
In client you need to write:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
while(!end)
{
int bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == 100)
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.
The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:
So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.
This is just a suggestion of a possible protocol. You could also get rid of "Type".
So it would be something like:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
int bytesToRead = messageByte[1];
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == bytesToRead )
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.
import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;
class Test
{
public static void main(String[] args)
{
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
Socket clientSocket;
ServerSocket server;
server = new ServerSocket(30501, 100);
clientSocket = server.accept();
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);
int bytesToRead = byteBuffer.getShort();
System.out.println("About to read " + bytesToRead + " octets");
//The following code shows in detail how to read from a TCP socket
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length() == bytesToRead )
{
end = true;
}
}
//All the code in the loop can be replaced by these two lines
//in.readFully(messageByte, 0, bytesToRead);
//dataString = new String(messageByte, 0, bytesToRead);
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
Prefix the call with Module2 (ex. Module2.IDLE
). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.
Here is what I was trying to do and how I did it. I think you wanted to do something similar. I had a table with several rows and on each row I had an input with type image. I wanted to pass an id when the user clicked that image button. As you noticed the value in the tag is ignored. Instead I added a hidden input at the top of my table and using javascript I put the correct id there before I post the form.
<input type="image" onclick="$('#hiddenInput').val(rowId) src="...">
This way the correct id will be submitted with your form.
Thanks a lot guys for your quick comments.
This is what i will be using now. Posting the function here so that somebody may use it.
public function getDayOfWeek($pTimezone)
{
$userDateTimeZone = new DateTimeZone($pTimezone);
$UserDateTime = new DateTime("now", $userDateTimeZone);
$offsetSeconds = $UserDateTime->getOffset();
//echo $offsetSeconds;
return gmdate("l", time() + $offsetSeconds);
}
Report if you find any corrections.
It allows servlets to have multiple servlet mappings:
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/bill</url-pattern>
</servlet-mapping>
It allows filters to be mapped on the particular servlet:
<filter-mapping>
<filter-name>Filter1</filter-name>
<servlet-name>Servlet1</servlet-name>
</filter-mapping>
Your proposal would support neither of them. Note that the web.xml
is read and parsed only once during application's startup, not on every HTTP request as you seem to think.
Since Servlet 3.0, there's the @WebServlet
annotation which minimizes this boilerplate:
@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {
Adding to answer by @Sasxa,
In Injectables
you can use class
normally that is putting initial code in constructor
instead of using ngOnInit()
, it works fine.
As Kintaro already says, person is a method (because of def) and always returns a new Person instance. As you found out it would work if you change the method to a var or val:
val person = new Person("Kumar",12)
Another possibility would be:
def person = new Person("Kumar",12)
val p = person
p.age=20
println(p.age)
However, person.age=20
in your code is allowed, as you get back a Person
instance from the person
method, and on this instance you are allowed to change the value of a var
. The problem is, that after that line you have no more reference to that instance (as every call to person
will produce a new instance).
This is nothing special, you would have exactly the same behavior in Java:
class Person{
public int age;
private String name;
public Person(String name; int age) {
this.name = name;
this.age = age;
}
public String name(){ return name; }
}
public Person person() {
return new Person("Kumar", 12);
}
person().age = 20;
System.out.println(person().age); //--> 12
I would just like to share the recent predicament I encounter with the RecyclerView. I hope that anyone experiencing the same problem will benefit.
My Project Requirement: So I have a RecyclerView that list some clickable items in my Main Activity (Activity-A). When the Item is clicked a new Activity is shown with the Item Details (Activity-B).
I implemented in the Manifest file the that the Activity-A is the parent of Activity-B, that way, I have a back or home button on the ActionBar of the Activity-B
Problem: Every time I pressed the Back or Home button in the Activity-B ActionBar, the Activity-A goes into the full Activity Life Cycle starting from onCreate()
Even though I implemented an onSaveInstanceState() saving the List of the RecyclerView's Adapter, when Activity-A starts it's lifecycle, the saveInstanceState is always null in the onCreate() method.
Further digging in the internet, I came across the same problem but the person noticed that the Back or Home button below the Anroid device (Default Back/Home button), the Activity-A does not goes into the Activity Life-Cycle.
Solution:
I enabled the home or back button on Activity-B
Under onCreate() method add this line supportActionBar?.setDisplayHomeAsUpEnabled(true)
In the overide fun onOptionsItemSelected() method, I checked for the item.ItemId on which item is clicked based on the id. The Id for the back button is
android.R.id.home
Then implement a finish() function call inside the android.R.id.home
This will end the Activity-B and bring Acitivy-A without going through the entire life-cycle.
For my requirement this is the best solution so far.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_show_project)
supportActionBar?.title = projectName
supportActionBar?.setDisplayHomeAsUpEnabled(true)
}
override fun onOptionsItemSelected(item: MenuItem?): Boolean {
when(item?.itemId){
android.R.id.home -> {
finish()
}
}
return super.onOptionsItemSelected(item)
}
Here is an option. This is just for the x coordinates.
var div1Pos = $("#div1").offset();
var div1X = div1Pos.left;
$('#div2').css({left: div1X});
import numpy as np
x = np.array([1,0,2,3,6])
non_zero_arr = np.extract(x>0,x)
min_index = np.amin(non_zero_arr)
min_value = np.argmin(non_zero_arr)
The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:
import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square')
plt.xlabel('x')
plt.ylabel('y')
plt.xticks(xi, x)
plt.title('compare')
plt.legend()
plt.show()
I'm not 100% sure what your sample code is supposed to do, but the following snippet should help you 'call the contacts list function, pick a contact, then return to [your] app with the contact's name'.
There are three steps to this process.
Add a permission to read contacts data to your application manifest.
<uses-permission android:name="android.permission.READ_CONTACTS"/>
Within your Activity, create an Intent that asks the system to find an Activity that can perform a PICK action from the items in the Contacts URI.
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
Call startActivityForResult
, passing in this Intent (and a request code integer, PICK_CONTACT
in this example). This will cause Android to launch an Activity that's registered to support ACTION_PICK
on the People.CONTENT_URI
, then return to this Activity when the selection is made (or canceled).
startActivityForResult(intent, PICK_CONTACT);
Also in your Activity, override the onActivityResult
method to listen for the return from the 'select a contact' Activity you launched in step 2. You should check that the returned request code matches the value you're expecting, and that the result code is RESULT_OK
.
You can get the URI of the selected contact by calling getData()
on the data Intent parameter. To get the name of the selected contact you need to use that URI to create a new query and extract the name from the returned cursor.
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c = getContentResolver().query(contactData, null, null, null, null);
if (c.moveToFirst()) {
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// TODO Whatever you want to do with the selected contact name.
}
}
break;
}
}
Full source code: tutorials-android.blogspot.com (how to call android contacts list).
It's additional information, and isn't an answer.
In C++11 you can write:
for (auto& it : s) {
cout << it << endl;
}
instead of
for (auto it = s.begin(); it != s.end(); it++) { cout << *it << endl; }
It has the same meaning.
Update: See the @Alnitak's comment also.
I suggest merging develop and master with that command
git checkout master
git merge --commit --no-ff --no-edit develop
For more information, check https://git-scm.com/docs/git-merge
There are also these 'ways':
>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}
The excellent NWebsec library can upgrade your requests from HTTP to HTTPS using its upgrade-insecure-requests
tag within the Web.config
:
<nwebsec>
<httpHeaderSecurityModule>

Just Javascript (as requested)
Add this function somewhere on your page (preferably in the <head>
)
function clearBox(elementID)
{
document.getElementById(elementID).innerHTML = "";
}
Then add the button on click event:
<button onclick="clearBox('cart_item')" />
In JQuery (for reference)
If you prefer JQuery you could do:
$("#cart_item").html("");
You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.

just like Gregory Seront said here:
Actually if you downloaded the icons pack from the android web site, you will see that you have one folder per resolution named drawable-mdpi etc. Copy all folders into the res (not the drawable) folder in Android Studio. This will automatically make all the different resolution of the icon available.
but if your not getting the images from a generator site (maybe your UX team provides them), just make sure your folders are named drawable-hdpi, drawable-mdpi, etc. then in mac select all folders by holding shift and then copy them (DO NOT DRAG). Paste the folders into the res folder. android will take care of the rest and copy all drawables into the correct folder.
See this CodePen https://codepen.io/ella301/pen/vYLNmVg which I created. I used 3 CSS functions min, max and calc to make sure the left and right paddings are fluid between minimum 20px and maximum 120px.
padding: 20px max(min(120px, calc((100% - 1198px) / 2)), 20px);
Hope it helps!
If you are wanting to just copy the whole column, you can simplify the code a lot by doing something like this:
Sub CopyCol()
Sheets("Sheet1").Columns(1).Copy
Sheets("Sheet2").Columns(2).PasteSpecial xlPasteValues
End Sub
Or
Sub CopyCol()
Sheets("Sheet1").Columns("A").Copy
Sheets("Sheet2").Columns("B").PasteSpecial xlPasteValues
End Sub
Or if you want to keep the loop
Public Sub CopyrangeA()
Dim firstrowDB As Long, lastrow As Long
Dim arr1, arr2, i As Integer
firstrowDB = 1
arr1 = Array("BJ", "BK")
arr2 = Array("A", "B")
For i = LBound(arr1) To UBound(arr1)
Sheets("Sheet1").Columns(arr1(i)).Copy
Sheets("Sheet2").Columns(arr2(i)).PasteSpecial xlPasteValues
Next
Application.CutCopyMode = False
End Sub
I just posted a fix here that would also apply in this case - basically, you do a hex find-and-replace in your external library to make it think that it's ARMv7s code. You should be able to use lipo
to break it into 3 static libraries, duplicate / modify the ARMv7 one, then use lipo
again to assemble a new library for all 4 architectures.
I like to do this
input[type="text"]
{
background: rgba(0, 0, 0, 0);
border: none;
outline: none;
}
Setting the outline
property to none
stops the browser from highlighting the box when the cursor enters
You can also use a fadeIn/FadeOut Combo, too....
$('.test').bind('click', function(){
$('.div1').fadeIn(500);
$('.div2').fadeOut(500);
$('.div3').fadeOut(500);
return false;
});
I got this error generating a data frame consisting of timestamps and data:
df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp))
Adding the suggested solution works for me:
df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp), dtype=float))

The answer to this question is simple:
var varname = Request.Unvalidated["parameter_name"];
This would disable validation for the particular request.
<input type="text" disabled="disabled" />
is the valid markup.<input type="text" disabled />
is valid and used by W3C on their samples.Just add one of these two to the src url:
&wmode=Opaque
&wmode=transparent

byte[] buf = new byte[8192];
InputStream is = new FileInputStream(f);
int c = 0;
while ((c = is.read(buf, 0, buf.length)) > 0) {
oos.write(buf, 0, c);
oos.flush();
}
oos.close();
System.out.println("stop");
is.close();

}
The easiest way so far. Hope this helps.
You can also run this:
php artisan migrate:status
It makes a db connection connection to get migrations from migrations table. It'll throw an exception if the connection fails.

json_encode
will always add slashes.
Check some examples on the manual HERE
This is because if there are some characters which needs to escaped then they will create problem.
To use the json please Parse your json to ensure that the slashes are removed
Well whether or not you remove slashesthe json will be parsed without any problem by eval.
<?php
$array = array('url'=>'http://mysite.com/uploads/gallery/7f/3b/f65ab8165d_logo.jpeg','id'=>54);

<script type="text/javascript">
var x = jQuery.parseJSON('<?php echo json_encode($array);?>');
alert(x);
</script>
This is my code and i m able to parse the JSON.
Check your code May be you are missing something while parsing the JSON
Broken pipe simply means that the connection has failed. It is reasonable to assume that this is unrecoverable, and to then perform any required cleanup actions (closing connections, etc). I don't believe that you would ever see this simply due to the connection not yet being complete.
If you are using non-blocking mode then the SocketChannel.connect method will return false, and you will need to use the isConnectionPending and finishConnect methods to insure that the connection is complete. I would generally code based upon the expectation that things will work, and then catch exceptions to detect failure, rather than relying on frequent calls to "isConnected".
In RStudio, ensure the Environment
tab is in Grid
(not List
) mode.
Tick the object(s) you want to remove from the environment.
Click the broom icon.
As per this example:
import numpy as np
import matplotlib.pyplot as plt
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
plt.scatter(x, y)
plt.show()
will produce:
To unpack your data from pairs into lists use zip
:
x, y = zip(*li)
So, the one-liner:
plt.scatter(*zip(*li))
I also had the same problem, I searched for the answers many places. I got many similar answers to change the number of process/service handlers. But I thought, what if I forgot to reset it back?
Then I tried using Thread.sleep()
method after each of my connection.close();
.
I don't know how, but it's working at least for me.
If any one wants to try it out and figure out how it's working then please go ahead. I would also like to know it as I am a beginner in programming world.
You're looking for is called an IDENTITY column:
create table student (
sid integer not null GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1)
,sname varchar(30)
,PRIMARY KEY (sid)
);
A sequence is another option for doing this, but you need to determine which one is proper for your particular situation. Read this for more information comparing sequences to identity columns.
This solution is generic without reflection overhead.
public static Nullable<T> ParseNullable<T>(string s, Func<string, T> parser) where T : struct
{
if (string.IsNullOrEmpty(s) || string.IsNullOrEmpty(s.Trim())) return null;
else return parser(s);
}
static void Main(string[] args)
{
Nullable<int> i = ParseNullable("-1", int.Parse);
Nullable<float> dt = ParseNullable("3.14", float.Parse);
}
A handle is whatever you want it to be.
A handle can be a unsigned integer used in some lookup table.
A handle can be a pointer to, or into, a larger set of data.
It depends on how the code that uses the handle behaves. That determines the handle type.
The reason the term 'handle' is used is what is important. That indicates them as an identification or access type of object. Meaning, to the programmer, they represent a 'key' or access to something.
In addition to the published answers I can say that a metaclass
defines the behaviour for a class. So, you can explicitly set your metaclass. Whenever Python gets a keyword class
then it starts searching for the metaclass
. If it's not found – the default metaclass type is used to create the class's object. Using the __metaclass__
attribute, you can set metaclass
of your class:
class MyClass:
__metaclass__ = type
# write here other method
# write here one more method
print(MyClass.__metaclass__)
It'll produce the output like this:
class 'type'
And, of course, you can create your own metaclass
to define the behaviour of any class that are created using your class.
For doing that, your default metaclass
type class must be inherited as this is the main metaclass
:
class MyMetaClass(type):
__metaclass__ = type
# you can write here any behaviour you want
class MyTestClass:
__metaclass__ = MyMetaClass
Obj = MyTestClass()
print(Obj.__metaclass__)
print(MyMetaClass.__metaclass__)
The output will be:
class '__main__.MyMetaClass'
class 'type'
I have created a function that allows me to obtain this feature:
function redirect_blank(url) {
var a = document.createElement('a');
a.target="_blank";
a.href=url;
a.click();
}
Just follow the steps in this URl: CLICK HERE
This is a more tolerate way to handle this with user input. This regex will match both "100" or "100.1" but doesn't allow for negative numbers.
/^(\d+)(\.\d+)?$/
it defaults to submitting a form, easiest way is to add "return false"
<button type="cancel" onclick="window.location='http://stackoverflow.com';return false;">Cancel</button>

One way can be to circularly store the values in the buffer array. and calculate average this way.
int j = (int) (counter % size);
buffer[j] = mostrecentvalue;
avg = (avg * size - buffer[j - 1 == -1 ? size - 1 : j - 1] + buffer[j]) / size;
counter++;
// buffer[j - 1 == -1 ? size - 1 : j - 1] is the oldest value stored
The whole thing runs in a loop where most recent value is dynamic.
Use FB static method getCurrentProfile() of Profile class to retrieve those info.
Profile profile = Profile.getCurrentProfile();
String firstName = profile.getFirstName());
System.out.println(profile.getProfilePictureUri(20,20));
System.out.println(profile.getLinkUri());
I finally understood what was going on.
When creating an integration test on a statement saving an object, it is recommended to flush the entity manager so as to avoid any false negative, that is, to avoid a test running fine but whose operation would fail when run in production. Indeed, the test may run fine simply because the first level cache is not flushed and no writing hits the database. To avoid this false negative integration test use an explicit flush in the test body. Note that the production code should never need to use any explicit flush as it is the role of the ORM to decide when to flush.
When creating an integration test on an update statement, it may be necessary to clear the entity manager so as to reload the first level cache. Indeed, an update statement completely bypasses the first level cache and writes directly to the database. The first level cache is then out of sync and reflects the old value of the updated object. To avoid this stale state of the object, use an explicit clear in the test body. Note that the production code should never need to use any explicit clear as it is the role of the ORM to decide when to clear.
My test now works just fine.
ALL YOU HAVE TO DO:

<td> CELL 5 </td>
</tr></table>
CSS:
#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/
if you have th
you need to set it too like this:
#my-table th{width:2000px;}
This solution will play the video upon clicking. You'll need to edit your picture to add a button image yourself.
You're going to need the URL of your picture and the YouTube video ID. The YouTube video id is the part of the URL after the v=
parameter, so for https://www.youtube.com/watch?v=DODLEX4zzLQ the ID would be DODLEX4zzLQ
.
<div width="560px" height="315px" style="position: static; clear: both; width: 560px; height: 315px;"> <div style="position: relative"><img id="vidimg" width="560px" height="315px" src="URL_TO_PICTURE" style="position: absolute; top: 0; left: 0; cursor: pointer; pointer-events: none; z-index: 2;" /><iframe id="unlocked-video" style="position: absolute; top: 0; left: 0; z-index: 1;" src="https://www.youtube.com/embed/YOUTUBE_VIDEO_ID" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div></div>
<script type="application/javascript">
// Adapted from https://stackoverflow.com/a/32138108
var monitor = setInterval(function(){
var elem = document.activeElement;
if(elem && elem.id == 'unlocked-video'){
document.getElementById('vidimg').style.display='none';
clearInterval(monitor);
}
}, 100);
</script>
Be sure to replace URL_TO_PICTURE and YOUTUBE_VIDEO_ID in the above snippet.
To clarify what's going on here, this displays the image on top of the video, but allows clicks to pass through the image. The script monitors for clicks in the video iframe, and then hides the image if a click occurs. You may not need the float: clear
.
I haven't compared this to the other answers here, but this is what I have used.
The latter is preferred, because it will handle subclasses properly. In fact, your example can be written even more easily because isinstance()
's second parameter may be a tuple:
if isinstance(b, (str, unicode)):
do_something_else()
or, using the basestring
abstract class:
if isinstance(b, basestring):
do_something_else()
In Addition to @Yifei answer. If you have special character like @, &, $
You have to go with percent-encode | encode the special characters. E.g. instead of this:
http://foo:B@[email protected]:80
you write this:
http://foo:B%[email protected]:80
So @
gets replaced with %40
.
Given this .env
file:
DB_NAME=foo
DB_USER=bar
DB_PASSWORD=baz
And this mongo-init.sh
file:
mongo --eval "db.auth('$MONGO_INITDB_ROOT_USERNAME', '$MONGO_INITDB_ROOT_PASSWORD'); db = db.getSiblingDB('$DB_NAME'); db.createUser({ user: '$DB_USER', pwd: '$DB_PASSWORD', roles: [{ role: 'readWrite', db: '$DB_NAME' }] });"
This docker-compose.yml
will create the admin database and admin user, authenticate as the admin user, then create the real database and add the real user:
version: '3'
services:
# app:
# build: .
# env_file: .env
# environment:
# DB_HOST: 'mongodb://mongodb'
mongodb:
image: mongo:4
environment:

DB_USER: $DB_USER
DB_PASSWORD: $DB_PASSWORD

There's a discussion here that might be useful.
From my own (limited) exposure, I'd say that shoes was the most fun and probably the "easiest" to get into. Be warned, however, that figuring out what was wrong when something breaks can be tricky (at least, it was for me).
For a real-world application that I was planning to deploy to real-world users, I think I'd go with wxruby.
keytool
comes with the Java SDK. You should find it in the directory that contains javac
, etc.
Not a solution to the concrete example above, but there may be many reasons why you get this error message. I got it when I accidentally added a shared module to the module declarations list and not to imports.
In app.module.ts:
import { SharedModule } from './modules/shared/shared.module';
@NgModule({
declarations: [
// Should not have been added here...
],
imports: [
SharedModule
],
$(selector).change()
Longer slower alternative, better for abstraction.
$(selector).trigger("change")
C++11 FAQ mentions below points:
conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer.
enum color
{
Red,
Green,
Yellow
};
enum class NewColor
{
Red_1,
Green_1,
Yellow_1
};
int main()
{
//! Implicit conversion is possible
int i = Red;
//! Need enum class name followed by access specifier. Ex: NewColor::Red_1
int j = Red_1; // error C2065: 'Red_1': undeclared identifier
//! Implicit converison is not possible. Solution Ex: int k = (int)NewColor::Red_1;
int k = NewColor::Red_1; // error C2440: 'initializing': cannot convert from 'NewColor' to 'int'
return 0;
}
conventional enums export their enumerators to the surrounding scope, causing name clashes.
// Header.h
enum vehicle
{
Car,
Bus,
Bike,
Autorickshow
};
enum FourWheeler
{
Car, // error C2365: 'Car': redefinition; previous definition was 'enumerator'
SmallBus
};
enum class Editor
{
vim,
eclipes,
VisualStudio
};
enum class CppEditor
{
eclipes, // No error of redefinitions
VisualStudio, // No error of redefinitions
QtCreator
};
The underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.
// Header1.h
#include <iostream>
using namespace std;
enum class Port : unsigned char; // Forward declare
class MyClass
{
public:
void PrintPort(enum class Port p);
};
void MyClass::PrintPort(enum class Port p)
{
cout << (int)p << endl;
}
.
// Header.h
enum class Port : unsigned char // Declare enum type explicitly
{
PORT_1 = 0x01,
PORT_2 = 0x02,
PORT_3 = 0x04
};
.
// Source.cpp
#include "Header1.h"
#include "Header.h"
using namespace std;
int main()
{
MyClass m;
m.PrintPort(Port::PORT_1);
return 0;
}
i wrote a small function.. but works for me
def conv(strng):
k=strng
k=k.replace('\a','\\a')
k=k.replace('\b','\\b')
k=k.replace('\f','\\f')
k=k.replace('\n','\\n')
k=k.replace('\r','\\r')

You need to set the classpath to find your compiled class:
java -cp C:\Users\Matt\workspace\HelloWorld2\bin HelloWorld2
To remove you tube controls
and title
you can do something like this
<iframe width="560" height="315" src="https://www.youtube.com/embed/zP0Wnb9RI9Q?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen ></iframe>
_x000D_
showinfo=0
is used to remove title and &controls=0
is used for remove controls like volume,play,pause,expend.
In addition to the answers above, you can check the type of object using type(plt.subplots())
which returns a tuple, on the other hand, type(plt.subplot())
returns matplotlib.axes._subplots.AxesSubplot
which you can't unpack.
e.currentTarget
is always the element the event is actually bound do. e.target
is the element the event originated from, so e.target
could be a child of e.currentTarget
, or e.target
could be === e.currentTarget
, depending on how your markup is structured.
This answer is for docker-compose version 2 and it also works on version 3
You can still access the data when you use depends_on.
If you look at docker docs Docker Compose and Django, you still can access the database like this:
version: '2'
services:
db:
image: postgres
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
What is the difference between links and depends_on?
links:
When you create a container for a database, for example:
docker run -d --name=test-mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -P mysql
docker inspect d54cf8a0fb98 |grep HostPort
And you may find
"HostPort": "32777"
This means you can connect the database from your localhost port 32777 (3306 in container) but this port will change every time you restart or remove the container. So you can use links to make sure you will always connect to the database and don't have to know which port it is.
web:
links:
- db
depends_on:
I found a nice blog from Giorgio Ferraris Docker-compose.yml: from V1 to V2
When docker-compose executes V2 files, it will automatically build a network between all of the containers defined in the file, and every container will be immediately able to refer to the others just using the names defined in the docker-compose.yml file.
And
So we don’t need links anymore; links were used to start a network communication between our db container and our web-server container, but this is already done by docker-compose
Express dependency between services, which has two effects:
docker-compose up
will start services in dependency order. In the following example, db and redis will be started before web.docker-compose up SERVICE
will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.Simple example:
version: '2'
services:
web:
build: .
depends_on:
- db
- redis
redis:
image: redis
db:
image: postgres
Note: depends_on will not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.
virtualenv --python=/usr/local/bin/python3 <VIRTUAL ENV NAME>
this will add python3
path for your virtual enviroment.
Try this:
v=spf1 ip4:abc.de.fgh.ij ip4:klm.no.pqr.st ~all
WSDL
(Web Service Description Language
) from a Web Service URL.Is possible from SOAP Web Services:
http://www.w3schools.com/xml/tempconvert.asmx
to get the WSDL we have only to add ?WSDL
, for example:
I also encountered the same problem on Mac OSX 10.6.8 and unfortunately adding #include <stdint.h>
or <cstdint.h>
to the corresponding file did not solve my problem. However, after more search, I found this solution advicing to add #include <sys/types.h>
which worked well for me!
I finally found the way to do what the OP wanted. It's as simple as:
git log --graph [branchname]
The command will display all commits that are reachable from the provided branch in the format of graph. But, you can easily filter all commits on that branch by looking at the commits graph whose *
is the first character in the commit line.
For example, let's look at the excerpt of git log --graph master
on cakephp GitHub repo below:
D:\Web Folder\cakephp>git log --graph master
